Fighting Cyber-Crime Term Paper Example | Topics and Well Written Essays - 1250 words

Fighting Cyber-Crime - Term Paper Example This is because: 1. Every country has their own and separate legal, technical and organizational issues. 2. All information is stored in free-text format. 3. Information keeps changing dynamically. Thus, it has become a biggest international challenge. So how are they fighting against cybercrime? This is the topic of discussion in this task. What is Cybercrime? Cybercrime is any illegal activity that is conducted through the use of computers, the internet and computer network. There are many kinds of cybercrimes that exist: internet fraud, computer hacking, spreading of malicious code or viruses, cyber piracy and many more. And new types of cybercrime keep on being introduced. (Yang, 2008, p. 32). There are many reasons why people commit cybercrime; some of which are as follows: 1. Intellectual: when hackers gain illegal access to information on a secured website or crack passwords. 2. Emotional: when hackers take revenge from any employee of a company by giving threats through the u se of emails. 3. Financial: when hackers gain money through internet fraud. 4. Accessibility: when people download pirated software from the internet. Hence, cybercrime is not an accidental approach; it is an intentional act to gain some or the other kind of benefit on the part of the person committing it. (Cross and Shinder, 2008, p. 29). Some Examples of Cybercrimes Bob Smith who was a residence of Oklahoma, observed that his credit card had been used by some criminal who did fraudulent purchases. Two accounts had been opened with his information in two different banks. The criminal further applied for a loan in Dallas to buy a car and he changed the address of Bob to some address in Dallas which was a fake address. This was an example of use of internet fraud which is a cybercrime. (Cross and Shinder, 2008, p. 4). On 8 March, 2008, some data thieves broke into computers of chain of supermarkets Sweetbay and Hannaford Brothers, and stole around 4.2 billion credit card and debit ca rd numbers. A person’s email account password was hacked and his account was misused for sending malicious code to the contacts in the person’s address book. As the people receiving the malicious code think that it is coming from their friend, they open it and execute the attachments which infect their computer with the malicious code. (Nagpal, 2008, p. 133). Fighting Against Cybercrime The police should not be the only one involved in fighting against cybercrime. Legislators should also perform their part by making appropriate laws. Furthermore, the IT community and the society themselves should report the incidents of cybercrimes to the higher authorities as well as they should take measures to prevent themselves from becoming victim to these crimes. To fight against cybercrime, the following steps are being taken: 1. Educating the IT Professionals: As they already understand computer security, IT professionals are further made aware of computer crimes in which they are educated about the law which states what things come under computer crime and what things do not. The IT professionals are also being included in the law making in which they share their expertise. Furthermore, they are being involved with the police in the investigation of any computer crime scene so that they can give technical help and advice through their expertise.

Internet Mental Health Issues Essay Example for Free

Internet Mental Health Issues Essay Mental health services conducted on the Internet have been described as e-therapy, online counseling, e -mail therapy, Internet-based therapy, and similar terminology. Online therapy services may be provided as an adjunct to more traditional forms of mental health treatment, or may be initiated without any offline contact between the therapist and client. Currently, there are a variety of websites providing links and information regarding online therapy. As I was reading about benefits and risks in using internet as a source for mental health services, I realized that there are a lot of factors that make it a controversial issue. There are many pro and con to its benefits. Some Pros are the convenience of a client, Flexibility in scheduling, Anonymous and private, Access to those with physical disabilities; emotionally safe environment on of my biggest issues is making use of the time-delay (email) to work on issues. Appeal to those who are shy, uncomfortable with face-to-face treatment and make them feel more those who are shy more comfortable. Some disadvantages are Privacy, security and privilege cannot be guaranteed, Lack of patient skills to use the Absence of face-to-face therapy relationship, Lack of behavioral cues may lead to problems in treatment and most importantly is Urgent, crises, or suicidal issues may not receive immediate and appropriate attention. I work in a Community clinic where we offer many treatments one of them is therapy also. As I came across this assignment I ask one of our doctors what they believed. One of the doctors sends in miner cases it could be useful as long as is a well program with credentials and the issues are not really serious. At this time we are transitioning from paper charts to computers so most of the time there sitting in front of the computer typing away while the patient is speaking. It made me realized that in a way internet and mental services are becoming more and more essential for each  other. When I was reading the website for American Psychological Association it provided me the ethics they have to fallow when they provide service public advice or comment via print, Internet or other electronic transmission, they take precautions to ensure that statements (1) are based on their professional knowledge, training or experience in accord with appropriate psychological literature and practice; (2) are otherwise consistent with this Ethics Code; and (3) do not indicate that a professional relationship has been established with the recipient. I believe in conclusion we could benefit from these services as long as we are really aware that they are legit and trustworthy. In my case I believe sometimes I could benefit from therapy but simply have no time. One of the reasons I choose online schooling. Definitely I would use these services and give it a try. There are programs offer here in California that can help you as a guide to search for help. The Board of Behavioral Sciences (BBS) would like to make the following recommendations to California consumers who choose to seek therapy or counseling over the Internet. Individuals, who provide psychotherapy or counseling, either in person, by telephone, or over the Internet, are required by law to be licensed. Licensing requirements vary by state. Individuals who provide psychotherapy or counseling to persons in California are required to be licensed in California. Such licensure permits the consumer to pursue recourse against the licensee should the consumer believe that the licensee engaged in unprofessional conduct. References 1.

Hospice Care: Death With Dignity Essay -- Dying with Dignity

The beginning of life is celebrated. Books and resources are shared among friends and family in preparation for becoming a new parent. So, what happens as one approaches the end of life? Unfortunately, the same care and sharing rarely occurs in those circumstances and many face the prospect of dying unprepared. Though most people state they would prefer to die at home, this is often not where death occurs. Many Americans spend their last days attached to medical apparatus that keeps the body alive, but it does not allow for communication with family and often requires heavy sedation. Additionally, this level of treatment comes at a high price. As a society, we must become as comfortable in addressing the end of life process as we are with the beginning of life. One way that this can be done more effectively is through increased knowledge and use of hospice care. Hospice care is a viable option that provides health care cost savings, comfort to the patient, and support to the caregivers, however as hospice systems become more commercialized, care must be taken to avoid the pitfalls that are inherent in larger organizations. Hospice care is a relatively young option in the United States, with the first hospice organization founded in 1971 after gaining acceptance in England in the 1950s (Jensen, 2012). Hospice care is provided to those who are diagnosed with a terminal condition that is expected to culminate in death within six months. Unlike regular health care which focuses on curative procedures, hospice services focus on the comfort of the patient in order to ease the process of dying. These services provide benefits to the patient and the caregivers, as well as showing cost savings. It is no secret that healt... ...NHPCO facts and figures: Hopice care in America. Alexandria, VA.

Increasing Hate Crime Awareness in the US Essay

Though latest report released last October 2006 by the US Department of Justice – FBI’s Uniform Crime Reporting (UCR) Program showed a decrease in total number of reported incidents, 7,163 in 2005 vs. 7,649 in 2004 (Hate Crime Statistics 2005), there has been an inversely growing awareness on this topic among various stakeholders – legislators, law enforcement officials, and the American public – such that term â€Å"hate crime† has become a part of everyday vernacular among Americans. Three factors contributed to this growing awareness. Firstly, the organizational initiatives, normally the offended party group in order to protect their civil rights, are taking active roles, through their advocacy campaigns, support services and education programs. Prominent proponents, among others, are American Civil Liberties Union (ACLU) for all Americans, Anti-Defamation League (ADL) for the Jewish, Parents and Friends of Lesbians and Gays (PFLAG), Massachusetts Office on Disability (MOD), La Alianza Hispana for the Latin-Hispanics and National Association for the Advancement of Colored People (NAACP) for African-American group. Secondly, the Federal Government on its part, through the DA’s Office has a Civil Rights Unit composed of attorneys for education and intervention services, working in cooperation with victim-witness advocates. In addition, Governor’s Task Force on Hate Crime has its ‘Stop the Hate Website’ Campaign promoting awareness of hate crimes and providing resources for responding to and preventing such acts. Thirdly, concerned group initiatives, such as NGOs in the likes of Southern Poverty Law Center (SPLC) that combats hate, intolerance and discrimination through education programs and litigations, play an independent, third-party role in increasing hate crime awareness.

Preliminary Studies of Religion Depth Course: Christianity Essay

Christianity is more than a belief in one God. It isn’t just something a person is baptised into to. Christianity is a source of hope for those who doubt, it is a guide for those who are lost and it provides answers for those who wonder. Christianity is the belief in one true God and from there come various interpretations that religions such as Anglicanism, Christianity and Lutheranism have taken and formed a more specific faith. In this preliminary year we will explore the beliefs, values, ethics, rituals and practices of Christianity. The course will open your mind to enlighten and enrich your knowledge on what is, the worlds most dominated religion. We just have to look over history to see the impact that one man has made on a society. Today characteristics of Christianity stem from the major events of Christ’s life and various interpretations of his predecessors. Jesus was born to Joseph and Mary in Bethlehem in approximately 4 BCE. Up until age 30 we are unaware of the occurrences in Jesus’ life. Christians believe that God sent Jesus to preach God’s word and demonstrate the morals, values and ethics, through which Jesus lived. Christianity evolved around the first century AD, branching off from Judaism, Christianity shared the ethical teachings of Christ. Christians have faith in Jesus as the model of Christianity through the way he lived his life; preaching, healing and humbling the supreme presence of God. Jesus conveyed his unheard of message through parables to the outcasts of society; prostitutes, the disabled etc. were his followers. Faith came from the divine actions of healing, commanding the forces of nature and the forgiving of sins. So what do Christians believe? There are several principle beliefs of Christianity that share a commonness that dominates the foundations of Christianity. First of all they believe in the divinity as well as the humanity of Jesus Christ. This means that Christians take Jesus a legit being but that he is also one with God – divine. This leads on to the core belief of the death, resurrection and ascension of Christ. This belief in itself forms the foundation of all Christian beliefs which this event solidifies the dominance of Christ within Christianity. From this divine event, there is a core belief in the trinity, a belief that God exists as 3 beings Father, Son and Holy Spirit. So another legacy of Jesus Christ is evident in Christian ethics based from the 10 Commandments and the Beatitudes as well. The Ten Commandments are viewed as the Law of God, his divine message conveyed through the way one should live their life. The greatest commandment is found in Matthew 22:36-40 where he is asked what is the greatest commandment? He replies quite simply â€Å"You shall love the Lord your God with all your heart, all your soul and all your mind† Jesus also then goes on to emphasise the importance of the 2nd greatest commandment; â€Å"love your neighbor as yourself†. The Beatitudes laid down by Matthew and Luke are expressed as teachings through the blessings of various virtues of Christians. The Beatitudes and Ten Commandments are focused on Humility, Love and Compassion and are heavily practiced today through the interpretations of Christians. Christian practices refer to the way one practices their religion. In todays society Christian practices vary depending on the interpretations of Christian variants which include rituals and sacraments for example prayer, communion and baptism. Prayer is used as a spiritual connection to God and is highly encouraged throughout the bible. Communion and Baptism are both sacraments that again interpreted accordingly express ones faith and dedication to God. Baptism is the first initial step towards a relationship to God and following his Laws and the teachings of Jesus. Communion on the other hand relates back to the belief in the death and resurrection of Christ, it establishes belief and a relationship between human, Jesus and God. All of these Christian practices are fully implemented in the Churches of today’s Christian societies and have been practiced as a part of this religion for thousands of years. So where to from now? Year 11 is a year of growth and learning. We will look at these aspects in further detail to obtain the fullest knowledge of Christian practices beliefs and ethics and the impact these have through the legacy of Jesus Christ. Since the birth of Christ his legacy whilst yes wasn’t embraced completely throughout his lifetime has had a huge impact on the modern society, over approximately 2.1 billion people world wide follow the faith that was built from one man, one belief and one teaching that went against everything that society knew. The legacy of Jesus Christ is everlasting, a continuous evolution of the interpretation of the core values, teachings and beliefs of Christianity. Good luck for your journey that you will all take for year 11 and thank you for attentively listening to the legacy of Jesus Christ.

How the 1947 Truman Doctrine Contained Communism

How the 1947 Truman Doctrine Contained Communism When President Harry S. Truman issued what came to be known as the Truman Doctrine in March 1947, he was outlining the basic foreign policy that the United States would use against the Soviet Union and Communism for the next 44 years. The doctrine, which had both economic and military elements, pledged support for countries attempting to hold back Soviet-style revolutionary Communism. It symbolized the United States post-World War II global leadership role. Countering Communism in Greece Truman formulated the doctrine in response to the Greek Civil War, which itself was an extension of World War II. German troops had occupied Greece since April 1941, but as the war progressed, Communist insurgents known as the National Liberation Front (or EAM/ELAS) challenged Nazi control. In October 1944, with Germany losing the war on both the western and eastern fronts, Nazi troops abandoned Greece. Soviet General Secretary Josef Stalin supported the EAM/LEAM, but he ordered them to stand down and let British troops take over Greek occupation to avoid irritating his British and American wartime allies. World War II had destroyed Greeces economy and infrastructure and created a political vacuum that Communists sought to fill. By late 1946, EAM/ELAM fighters, now backed by Yugoslav Communist leader Josip Broz Tito (who was no Stalinist puppet), forced war-weary England to commit as many as 40,000 troops to Greece to ensure it did not fall to Communism. Great Britain, however, was also financially strapped from World War II, and on February 21, 1947, it informed the United States that it was no longer able to financially sustain its operations in Greece. If the United States wanted to halt the spread of Communism into Greece, it would have to do so itself. Containment Halting the spread of Communism had, in fact, become the United States basic foreign policy. In 1946, American diplomat George Kennan, who was minister-counselor and chargà © daffaires at the American Embassy in Moscow, suggested that the United States could hold Communism at its 1945 boundaries with what he described as a patient and long-term containment of the Soviet system. While Kennan would later disagree with some elements of American implementation of his theory (such as involvement in Vietnam), containment became the basis of American foreign policy with Communist nations for the next four decades. The Doctrine to Stop Communism On March 12, Truman unveiled the Truman Doctrine in an address to the United States Congress. It must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressure, Truman said. He asked Congress for $400 million in aid for Greek anti-communist forces, as well as for the defense of Turkey, which the Soviet Union was pressuring to allow joint control of the Dardanelles. In April 1948, Congress passed the Economic Cooperation Act, better known as the Marshall Plan. The plan was the economic arm of the Truman Doctrine. Named for Secretary of State George C. Marshall (who had been United States Army chief of staff during the war), the plan offered money to war-torn areas for the rebuilding of cities and their infrastructures. American policy-makers recognized that, without quick rebuilding of war damage, countries across Europe were likely to  turn to Communism.

First Come, First Served

First Come, First Served First Come, First Served First Come, First Served By Maeve Maddox The expression first come, first served began life as a proverb having the same sense as the early bird catches the worm. Both proverbs are admonitions against dawdling.†¨ The proverb was adopted by shopkeepers to convey the idea that customers would be served in the order of their arrival. In case of limited quantities, latecomers would be out of luck. And if the local squire got there after the char lady, hed have to wait his turn. The expression has become so common in modern times that the abbreviation FCFS and even Fcfs is seen in advertising and on ticket-selling sites. Because the expression originated before the 1900s when the idiom changed, modern speakers and writers have trouble with the usage. A common error is to write the phrase as first come, first serve. The confusion arises from thinking that come is the same kind of verb form as serve and that theyre supposed to match. One way to look at it is to think of first come, first served as an elliptical form of the first to come will be the first to be served. Another is to recognize come as a past participle or adjectival verb form. Consider: First seen, first treated. First gone, first missed. In first come, first served, come functions as an adjective. Its not a common usage these days, but I actually found a contemporary example in a song written by Steeleye Span, a British electric folk band. Its from their 2004 album They Called Her Babylon: some said, â€Å"give him the beef, the beef,† some said, â€Å"give him the bone.† and some said, â€Å"give him nothing at all but let the beggar roam.† then up and spake the new-come lord, a saucy word spoke he, â€Å"pass round the cup, let my rival sup, then send him on his way.† Confusion about the expression involves punctuation as well as spelling. No comma Bookings must be made by midnight 22nd June, so hurry, spaces are limited and available on a first come first served basis. Comma Free flights from British Airways for small businesses looking to export. There are 4,000 up for grabs on a first come, first served basis. Hyphens Delta Airlines accepts pets on a first-come, first-serve basis. Quotation marks NEWCASTLE United  is set to be sold on a first-come, first-served basis. I vote for the unhyphenated, unquoted comma version: The new phones will be sold on a first come, first served basis. Of course the problems of verb form and punctuation can be avoided entirely by going with FCFS. Want to improve your English in five minutes a day?

The Role that Alternative Dispute Resolution Plays in the English Essay

The Role that Alternative Dispute Resolution Plays in the English Civil Justice System - Essay Example Cumulatively, the main question is whether or not the aims of civil justice report facilitate greater access to justice for disputants via alternative dispute resolution. This study is therefore divided into two parts. The first part of this study analyses alternative dispute resolution and the second part of the paper analyses the extent to which alternative dispute resolution is facilitated by the English civil justice system. Alternative Dispute Resolution Alternative dispute resolution broadly defined implies the use of non-traditional court adjudication of disputes. Invariably this means the use of mediation, conciliation or arbitration as opposed to formal litigation.6 However, the term alternative dispute resolution received academic attention beginning in the 1980s and was used as a frame of reference to an option for resolving civil disputes in the absence of lawyers or legal input. By the end of the decade of the 1980s alternative dispute resolution institutions began to fo rm and gain currency in the UK. By the 1990s, alternative dispute resolution was perceived as an important solution to the evolving litigious culture which created delays, inordinate costs and created a significant problem for ordinary citizens to gain access to civil litigation.7 According to Stipanowich over the last two or more decades, there has been a consistent effort on the part of lawyers, the judiciary, business entities and governments to cooperate on the formation of strategies and policies calculated to provide for the more efficient and less costly management and resolution of conflicts which invariably includes ADR processes.8 Arbitration is often described as an informal and rather simple version of adjudication via the courts in which the formal requirements relative to procedural laws such as discovery are typically waived and instead adopt a more informal process.9 Arbitration derives its strength from the disputant’s agreement to submit to arbitration and t o abide by any award administered by the arbitrator who is usually a tribunal of three independent decision-makers or a single arbitrator.10 It would therefore appear that arbitration, is poised to forego or at the very least reduce the cost and time involved in litigation by removing the procedural complexities and guidelines established for civil litigation and thereby dispensing with the need for the involvement of lawyers. In this regard, arbitration as an alternative dispute resolution, with its emphasis on party autonomy arguably plays a significant role in the reduction of time and cost involved in resolving civil disputes and therefore contributes to facilitating the drive for broadening access to civil

Analytical essay Example | Topics and Well Written Essays - 750 words - 1

Analytical - Essay Example What remains in her mind is the illusion that her father is still alive and has the control over her. At one event with the townpeople, she even told them that his father is alive and kicking. "Miss Emily met them at the door, dressed as usual and with no grief on her face. She told them that her father was not dead...Just as they were about to resort to law and force, she broke down, and they buried their father quickly." (Brooks and Warren,1959) The death of her father, although it creates a terrible anguish in her heart give her the signal to exercise her freedom. Thirty years later when she met Homer Barron---the love of her life. As the reader is told, Miss Emily was loved by many men of the town. Therefore it is not surprising that a man like Homer would fell in love with Emily. On the other hand, her only desire is to find infinite happiness in life and he found it within this man. In short, the two get married. Her decision to settle down was good enough for she knows no one can control her. The relationship could be somewhat strange but the revelation that she kills her husband is not so surprising. The fact that she suffers from severe trauma and mental insanity , she could commit such criminal act. Her acceptance of illusion and denial of reality only shows that she is out of her mind. Even until her death, anguish and suffering still remains. "After Miss Emily died, the townpeople had to go remove her body. The unsuspecting thing that happened in her house was that she had been sleeping with Homers old decayed body for many years. Even after she kills Homer Barron, she sleeps with his corpse - something that did not bother her at all." (Death As Central Theme In "A Rose for Emily".) Faulkner wants his readers to understand that Emilys life is like a rose. A rose, particularly a red rose can represent many things such as love or hatred. Her relationship with her father and her lover can be compared to a red rose. She loves her father so

MOTO car manufacturer Assignment Example | Topics and Well Written Essays - 8000 words

MOTO car manufacturer - Assignment Example The new type of car to be offered changes the product entry dynamic. The new type of car should be seen as entering a new market. International institutions and home country governments are external forces that can also affect bargaining outcomes Eden, L., & Molot, M. (2002,). Such a phenomenon has a slow growth impact on profits. An over view of the different markets are summarized here. The industrial climate is under review. This is especially so for the mass production activity (Harris, R., & Buzzelli, M. (2005,). The uncertainty makes it necessary for them to protect the local auto manufacturer. MOTO Company is obviously a foreign company. The auto industry here has huge government backing. It is dominated by two top Japanese auto manufactures already. Both of the companies have a major share of the market. In addition they have huge research and development facilities there. The country has very little to say about environmental friendly cars. It seems as thought the country is interested in first saving foreign exchange. This has been achieved by the production of cars by these two major Japanese manufacturers. Their other apparent interest is in earning foreign exchanges. This can be seemed by the commitment of the tow major manufactures to produce not only cars but to also produce parts, both of which are in excess of what is needed for the Australian market. The excess production is expressly for the foreign market. A good example is that the cars produced are both right hand and left hand drive cars. This accommodates the two possible markets of the world. The government has just provided massive infusions of money. There is no stipulation for environmental type products. This is something that might bee considered in about five years. There is not likely hood it would be sooner. By then the USA market experience would have been working. It would be possible to see what if anything can be

Business law assignment - Essay Example e marijuana will still be an illegal drug in other states, businesses are more likely to restrict their operations with Colorado and Washington where it is legal. When it comes to the American legal system, federal law is regarded as a higher authority than state laws as they may not prevail consistently throughout the whole nation, unlike federal law. At many instances, state law comes into conflict with federal law, in which case, a federal preemption is enacted where the state law is invalidated in the light of their inconsistencies (O’Reilly, 72). The legal aspect revolving any business is an important determinant of its activities and operations, as they occur in compliance or in conflict with the state order or law. The legalization of pot opened way for new business and ventures as investments poured into the relatively infant area of legalized business activity. One aspect of marijuana legalization is the end of illegal criminal activity associated with underground marijuana sale. With the new development, businesses are hopeful of generating high profits with new business ideas revolving around marijuana. Apart from its use as a recreational drug, marijuana is also known for its helpful medicinal properties. Due to this purpose, marijuana research centers could be established to carry out further research as to its use for curing diseases and healing some form of cancers. According to the White House, a number of states possess laws regarding medical usage of marijuana with Colorado and Washington completely legalizing its usage (n.pag.). A factor to consider is the dual status which implies that states other than Colorado and Washington still treat marijuana as an illegal drug, whose sale and trade is a criminal act. With its legalization in Colorado and Washington, it is evident that the marijuana related business is thriving. However, the nature of such businesses should be restricted within due to the legalities. This means that any marijuana

Smoking Cigarettes is Good for Your Health - Article Analysis Essay

Smoking Cigarettes is Good for Your Health - Article Analysis - Essay Example From the article, it is evident that the writer believes the only way to realize communication and draw the attention of readers is through taking this risk. Readers like reading stories that are the opposite of expectations. Although writers take the risk to explore a topic not previously done, they eventually bring new and viable ideas into the book. In writing to win a large number of readers, safety in writing is a risk that many writers overlook. Scholars have considered safety as a component with less weight in the art of writing (Tepper). Many people know that smoking is dangerous to one’s health to appoint that the cigarettes contain a warning of being harmful. However, the author brings a different idea to book, where he several advantages of smoking unlike what other writers do. In this case, it is risky for the author to choose such a sensitive topic and argue of benefits of smoking knowing very well that security agents are opposed to the idea. This means that the writer can be questioned by authorities hence risky to him. The idea that cigarettes are beneficial to humankind raises eyebrows and hence can rise the contest on the subject. Partiality in writing is most likely to increase the controversy and hence risks in writing. In whatever subject matter, the writer must argue on both sides. This means that the advantages and disadvantages must be well presented in the article. The author of the article analyses several disadvantages of smoking despite the fact that they are for the idea that smoking is health to one’s life. In an argumentative writing, the author must present both sides and show the strengths of each without been bias on one side., this means that the author should not take a side on whatever argument and should just make suggestions remaining partial at the end of the writing. Although the author tried to make a justification that smoking is healthy, disadvantaged of smoking are keenly presented in the article showin g the impartiality of the author. The difference in the presentation of ideas is from the diverse differences in both written and oral languages. With the growth of technology witnesses in the last past decades, language has moved from verbal to written. Every cultural setting has its norms regarding language and manner of presentations. As such, there is a classification of languages from standard, regional and local languages. Writers majorly concentrate with standard language. In the article, there is a proper use of standard language that is easily understood. Standard language goes hand in hand with the controversial topic (Ferraro). From this, the readers expect more of the article as they would when reading a normal scholarly article. To ensure that the author convinces the readers, facts and opinions are given and required evidence provided.

With the new development, businesses are hopeful of generating high profits with new business ideas revolving around marijuana. Apart from its use as a recreational drug, marijuana is also known for its helpful medicinal properties. Due to this purpose, marijuana research centers could be established to carry out further research as to its use for curing diseases and healing some form of cancers. According to the White House, a number of states possess laws regarding medical usage of marijuana with Colorado and Washington completely legalizing its usage (n.pag.). A factor to consider is the dual status which implies that states other than Colorado and Washington still treat marijuana as an illegal drug, whose sale and trade is a criminal act. With its legalization in Colorado and Washington, it is evident that the marijuana related business is thriving. However, the nature of such businesses should be restricted within due to the legalities. This means that any marijuana

Communication - Essay Example This paper discusses this with certain examples. Let’s suppose a workplace in which a male employee is talking to a female employee. The two are in some sort of an argument over a matter related to work. The male employee finally says, â€Å"You know what? I give up. No man can win an argument from a woman.† The female employee becomes offensive and says, â€Å"So you suggest I am right because I am a woman? Not because what I am saying is actually right?† She snaps at the male employee and walks out of the room. This explains how the use of sexist language can serve as a barrier to communication. Now let’s suppose a scenario in which two colleagues are dining together at the cafeteria. One of them is an Indian and the other is an American. The two are having gossip and a good time together. The American colleague orders a Pizza for himself and asks the Indian colleague what he would like to have. The Indian colleague replies, â€Å"I would like to have chicken curry.† Suddenly, the American colleague says, â€Å"Now I know why you Indians smell like curry.† The Indian colleague replies, â€Å"For the same reason that you Americans are so obese.† Seeds of dislike are planted in the hearts of both for each other.

Romeo and Juliet Annotated Biboliography Essay Example for Free

Romeo and Juliet Annotated Biboliography Essay This Shakespearean classic tells the tale of a young couple who fall deeply in love finding themselves separated from their happily ever after by their family’s century long conflict. Romeo and Juliet meet and immediately fall in love, their relationship progressing rapidly and living under fear of their family’s reactions they make panicky, over-stressed decisions and find themselves digging their grave deeper and deeper. Shakespeare’s inclusion of puns makes the play feel a bit lighter at times adding much needed humor to this tragedy while his use of metaphors makes amplifies the romance and tension of the play. Setting the play in sixteenth-century Verona, Italy added to the drama and exotic nature of the play, showing royalty, foreign laws and customs. This play will keep the reader interested while including characters you grow to love despite their ignorance and often terrible decisions. Although the story is well written and contains a good blend of humor all readers must be warned, it is not a â€Å"light read† but instead stays completely true to its devastating genre. The levels of depth in personality applied to all characters involved gave it the romantic story line modern classics like Stephanie Myer’s Twilight dream of achieving. Although this book is a practically mandatory read, because of the crude and somewhat gore-filled nature of the play I would suggest that it not be read to children under thirteen or so.

Overview of the Primary Health Care System in Hong Kong

Overview of the Primary Health Care System in Hong Kong Student name: MAN Ho Yan Introduction Hong Kong average life expectancy is one the longest city among the world, even longer than some developed countries such as America, Japan (Lee et al., 2016). According to the statistic provided by the Department of Health in 2016, the life expectancy of Hong Kong male and female are 81.2 and 87.3 respectively. The reason why Hong Kong is having this honor can be related to various factors. Generally speaking, more and more people have started to take care of their health. For example, they have a variety of food choice, buying food from many places with a relatively reasonable price. The Hong Kong government also pays lots of effort in health promotion, like encouraging people to do enough exercise per week and eat healthily with less oil, salt, sugar etc. Citizens are able to find this kind of health information easily through television, advertisements, or the Internet. In terms of policy making, Hong Kong government has set up regulations restricting smoking in Hong Kong. Smokin g in restricted area is prohibited, higher regulation in tobacco trading, as well as the advertisements of tobacco, posted or showed to the public. Together with the smoking cessation program provided by the government, the number of people smoke is kept decreasing throughout these years (Hong Kong Council on Smoking and Health, 2016). Nonetheless, another important factor that makes Hong Kong people can have the longest life expectancy in the world is due to Hong Kong has a comprehensive health care delivery system. Including both public and private health services, from out-patient clinic, specialist out-patient clinic, even in hospitalization, Hong Kong health care system has a high quality and high standard of health delivery service. With the advanced medical technology, all the Hong Kong citizens can enjoy the health service, no matter what kind of economic status of oneself. They can use the health service. Everyone will be provided with adequate health care services provided by all health criteria. As a result, Hong Kong citizens can have a higher chance to have a longer life expectancy. In the following paragraph, a brief overview of the current Hong Kong health care system will be discussed, followed by the discussion of one of the major roles of the whole system in Hong Kong, Primary Health Care, by looking at the working principles of the system and the services provided to the public. Last but not least, the health care system in Hong Kong though is comparatively perfect than other countries. There are some rooms of improvement, which will be discussed in the recommendation part. Hong Kong current Health Care System Nowadays the health care system in Hong Kong is running under a dual-track system, they are public and private sectors. These sectors deliver different services from primary, secondary and even tertiary care. Public health care sector is the core of the whole healthcare system, providing health services to all the citizens. In other words, the public healthcare sector is the basic system in maintaining the health of the community. On the other hand, private healthcare provides an alternative choice for citizens to choose (Ko, 2013). These services usually have a higher cost, but will provide a more accessible and relatively higher quality healthcare service than public healthcare service. If clients can afford the cost, they may choose private health care service according to their own desire (Kong, 2015). All public health care services in Hong Kong are regulated by the Food and Health Bureau, HKSAR. The major role of it is setting up policies and distributing resources to public healthcare services to operate and providing service for the community (HKSAR, 2016). Under the regulation of Food and Health Bureau, there are two more departments in providing different kinds of public health care services. The Department of Health is responsible for the management of public health like Chest Clinics, Student Health Services Centre, Maternal and Child Health Centres etc. The Hospital Authority is responsible for the management of public hospitals, for instance, public hospitals, general out-patient clinics, special out-patient clinics (HKSAR, 2016). Private health care service, involve mainly hospital services, such as private hospitals, private practitioners, and private Chinese practitioners. All the private hospitals, private medical clinics are regulated by the Department of Health, and they should obey the Hospitals, Nursing Homes and Maternity Home Registration Ordinance (Cap. 165) and the Medical Clinics Ordinance (Cap. 343) (HKSAR, 2010). 3. Primary Health Care Services Primary health care is an important category in the health care system since it helps to maintain the health of the community, the work should be done effectively and comprehensively. This is because primary health care is the first step of contact between patients with their family members and health professional (WHO, 2008). Generally speaking, primary health care aims to prevent any disease occur in the early stage, as well as improve personal health condition. These kinds of actions can help in lower the opportunity of suffering diseases and thus, reduce the needs of a high level of health care like that more intensive health care. The whole health expenditure can be reduced for both the client oneself and also the whole health care system (HKSAR, 2008). A proper and effective development of primary health care system can benefit the use of resources and their allocation to another part of the system. For example, primary health care for elderly, treatment on long-term disease et c. 3.1 Current Primary Heath Care Service in Hong Kong Being the first contact point of the health care, primary health care does include health promotion, patient-based health care, disease prevention, and medicine care. In Hong Kong, primary health care services are mainly provided by the private family doctors, public health care sectors will integrate with those private health care sectors to provide different dimension of specialist and hospital services. However, patients have to pay for all of the cost to the private health care services. Public health sectors its own will provide general out-patient clinics, for those who cannot afford the cost of private primary health service (HKSAR, 2010). The Department of Health functions various public activities for community care. With the working principle of protecting the health of the whole community and the population, Department of Health will bring along with disease surveillance, communicable diseases control among the community, public health regulation as well as licensing, impl ement different kinds of health measures, such as tobacco control etc. (HKSAR, 2010). In order to provide a comprehensive health care, different discipline or health care professionals should work together, including general practitioners, nurses, Chinese medicine practitioners, and related health care professionals and health care providers among the community. Early in 1990, the Working Party on Primary Health Care established a report, to have a comprehensive examination of the primary health care system in Hong Kong, as well as recommending the strategies in order to strengthen the system. Since then, different primary health care services started to be established. For example, in 1994, the Woman Health Service has been set up. Introduce health service for women who aged 64 or below. In 1995, the Student Health Service has been established, which give general medical checkup, health promotion etc. for primary and secondary students. Elderly Health Service was established in 1998, providing preventive care, giving support on elderly centres and elderly homes (Food and Health Bureau, 2010). Throughout the years, more and more primary health care services have been organised or being reformed. In October 2008, a reform of the Working Group on Primary Care has been established by the Health and Medical Development Advisory Committee and operated by the Secretary of the Food and Health Bureau (Food and Health Bureau, 2010). The working group is mainly on providing advice on critical development for primary care. Several working tasks have been set up by the group including establishing primary health care conceptual models and related framework protocols, constructing the Primary Care Directory, and recommending an effective primary health care service delivery model (HKSAR, 2010). All these working principles are aiming at enhancing primary health care service in Hong Kong. The group is composed of both representatives of public and private sectors, for instance, patients group, health professionals, health administrators, and related stakeholders. Regarding the working principles, the primary health care conceptual model and protocol is targeting on the conceptual models and guidelines on hypertension and Diabetes Mellitus for the use of health care professionals. Primary Care Directory is a program set up by the Primary Care Office, which is under the regulation of the Department of Health, established in 2010. This program aims at supporting and coordinating primary health care service development in Hong Kong, establishing primary health care developing strategies and operation. The Directory is operated by different health professionals, health administrators, and related stakeholders from the Food and Health Bureau. In order to have a better co-operation between various disciplines, and to ensure they have relevant professional knowledge to develop primary health care system (Primary Care Office, 2017). The government will also help in training primary health care providers and collaborate with the Directory and those health professionals. The public can assess to the Primary Care Directory to search for their own primary health care providers according to their health needs. In terms of community health networks, the Government will propose projects based on the conceptual models and consultation with the health care professionals, health care providers, public and private health care sectors, non-governmental organizations, and local universities. Aims at setting up localized health centre, provide a comprehensive and coordinate primary health care service to the community. 3.2 Primary Health Care for Elderly Aging population in Hong Kong is a serious problem, according to the statistic provided by the Census and Statistic Department in 2015, it is estimated that in mid-2024, 22% of the Hong Kong citizens are aged over 65 and over 65. Nonetheless, the number of elderly will keep increasing in the following years. 20 years later in 2044, the population rate for those aged 65 and over will become 31%. More elderly will have an effect on the labor workforce, more workers are needed to support those retired elderly (Tollefson, 2015). The increase of number of elderly also will affect to the health care system. Normally, elderly will have a higher chance of developing chronic disease due to the decrease on the body mechanism. As a result, they will use health services more often. The government has to put more resources in maintaining the health of this population. For example, health promotion, more resources to the hospitals in curing the chronic disease, ensuring all the functional ability etc. (Sin et al., 2015). A comprehensive primary health care framework is therefore needed to be established in order to relieve the pressure of the medical services and also the whole health care system in a long-term, to achieve a sustainable development. Primary health care in elderly is served as a preventive measure, a better control of the chronic disease etc. The services usually provided by the private family doctors. They will give health related information to the elderly, having risk assessment, and follow-up medication (Sin et al., 2015). The supportive measures not only help the elderly, but their family members also gain benefit from it. They can spend less time and money in paying for the health care service. 4. Recommendations 4.1 Allocation of the manpower As mentioned, most of the tasks are performed by the Department of Health, the health professionals, like doctors, nurses, even the Secretary of the Food and Health Bureau is come from a medical background. The workload of the health professionals, especially those who work in hospitals, is very high. In fact, they almost need to perform all the tasks. There is not enough manpower to take care of a huge amount of clients every day. From paper work or even the driver of the ambulance are all health professionals. The government should revise of the job allocation in hospitals or related work field, to lower the workload of the health professionals, and thus, have a better working performance to provide a higher quality of health care to the clients. 4.2 Use of Complementary and Alternative Medicine Nowadays in Hong Kong is mainly use conventional medicine as medical treatment. Although it still has its effectiveness, Complementary and Alternative Medicine (CAM) therapy is an alternative way that can be used in public primary health care service. CAM therapy refers to an approach using together with western medicine, focusing on the treatment of a whole person (Mayo Clinic, 2014). The Hong Kong Baptist Hospital is one of the hospitals that provide Chinese Medicine medication. However, the use of CAM therapy is not quite common in public health care sectors, most of the therapies are provided by the private sector. Therefore it is suggested that the Government can build up or set up clinics that mainly use CAM therapy for primary health care, letting those who cannot afford the high cost of private health care sector. A combination of CAM therapy and traditional medicine lower the use of main hospital resources and as a result, a better resource allocation. 4.3 A Balance between public and private health care sectors As mentioned by Griffiths (2012), private sector is the major provider of primary health care, around 70% of it is provided by family doctor, private clinics etc. Moreover, there are more and more private clinics being established, since the practitioners want to have more economic income. Therefore, the two sectors can cooperate with each other, such as the General Outpatient Clinic Public Private Partnership is one of the ways to solve this problem (Cheung, 2015). Even clients whenever use the private health care service can enjoy a lower cost if they are transferred from the public sector. This can lower the workload and the number of clients in public sectors, and also the clients can have a relatively better quality of primary health care service. The Government shall implements effective and comprehensive strategies between public and private health care sectors. 5. Conclusion Being the longest life expectancy among the world, it is no doubt that Hong Kong has several of advantages owing to this result. As mentioned from the above, the quality and standard of the health care system in Hong Kong is higher than many developed countries. This plays an important role for community health development. Primary health care system is the first step for the medical treatment between clients and medical providers. Therefor an effective and comprehensive primary health care system is essential. This can lower the time spending on medical treatment afterwards. The resources using in the system can be reallocate. However the whole still has some problems, government should cooperate with public and private health care sector in order to implement an effective policy for providing adequate medical service to the community. 6.

Drinking Games :: essays research papers

Drinking Games Drug Dealer Quite a simple game actually, with a low-mid boot factor. This is a game to play while doing other things at a party. To play the game you need one playing card for each participant. You always need one King and one Ace, and a variety of numbered cards some low, some mid, some high, but just one card per player. The cards are dealt face down, take a quick peek. The person who gets the King is the cop, the person who gets the ace is the drug dealer, everyone else are bystanders. It is the drug dealers job to very VERY discreetly wink at another player, this person while enventually say 'the deal has been made.' At this time the cop identifies him/herself and tries to figure out who the dealer is. The cop chooses a player, if wrong the cop drinks the number shown on the card, and then chooses again, if wrong again, he drinks the number on that card. When the cop chooses correctly, the drug dealer drinks the NUMBER OF CARDS remaining NOT the total of the numbers on the cards. After that, the cards are redealt and the game goes on. This is a great game for when people don't feel like playing a game because it's the regular socializing that helps disguise any winks and keep the cop on his/her toes. However, it helps alot if the players do sit in a circle while playing, and not spread around a room. Obviously if you want to increase the boot factor, play with high numbered cards. Fuzzy Duck A good get-to-know-ya kind of game. Simple supplie: people and beer. Low buzz factor. Not too bad of a game after everybody's had a few. Begin the game by saying "fuzzy duck" to the person to your left. That person then says "fuzzy duck" to the person on his/her left. This continues until someone decides to change the direction of play by saying "does he" (duzzy). "Does he" changes the direction and the phrase that is said. Not only does the direction change but the people must say "ducky fuzz." Now the game is going to the right with "ducky fuzz." The direction is then changed back by saying "duzzy." The words to say go back to "fuzzy duck." Any screw-ups ===> drink. After awhile when the mistakes are more frequent, it turns into, "Does he F**ck?" or "F**k he does." Variation: the same player cannot say the same thing consequtively within the same round. ie: if player 1 starts with "Fuzzy Duck," and play comes back around to him, he must say "Does He"

Critical Thinking: Evidence Based Practice (EBP) and “Person-In-Environment” (PIE) Essay

Critical thinking, what has happened to it? Is it apart of our daily lives or is it a part of the past? Can you tell me the definition of critical thinking or would every person’s response be different? Does today’s science have anything to do with critical thinking? How does evidence based practice (EBP) and â€Å"person-in-environment (PIE) relate to critical thinking? In this essay I will answer all of these questions plus give you more information on the subjects. So, by the end of this essay you should have a clear understanding of critical thinking: evidence based practice and â€Å"person-in-environment†. Let’s start with the question of what has really happened to critical thinking? It looks like to me we live in a very complicated fast paced world, where we all have problems and issues and at times they are very hard to comprehend. Yet still decisions have to be made. The interpretation of critical thinking goes as far back as the Socrates but in 1906 William Graham Sumner stated that the concept of critical thinking is: â€Å"the examination and test of propositions of any kind which are offered for acceptance, in order to find out whether they correspond to reality or not†. He goes on to say that â€Å"Men educated in it cannot be stampeded. They are slow to believe. They can hold things as possible or probable in all degrees without certainty and without pain. They can wait for evidence and weigh evidence. They can resist appeals to their dearest prejudices. † Another definition of critical thinking has been defined by Ku, K. (2009) as â€Å"judging information, evaluating alternative evidence and arguing with solid reasons. † (pg. 70) So it may seem too many that this notion of critical thinking (also embraced by educational theorists at the turn of the 20th century) is really declining in popularity in this new millennium. To others critical thinking, if somehow it became generalized in the world, would produce a new and very different world, a world which increasingly is not only in our interest but is necessary to our survival. Now after researching the subject of critical thinking I find out a lot of more information. Such as critical thinking is two things. One is the particular examination of an opinion or conclusion based on that specific examination. Two is when presented with a question, problem, or issue of someone’s opinion or conclusion a creative formulation is formed. I also found out that the practice of reasoning is something critical thinking concentrates on. Practicing self-awareness, tolerating ambiguity when faced with ethical dilemmas, and applying knowledge gained from multiple sources are all key components of critical thinking (Carey & McCardle 2011) Critical thinking is that mode of thinking — about any subject, content, or problem — in which the thinker improves the quality of his or her thinking by skillfully analyzing, assessing, and reconstructing it. Critical thinking is self-directed, self-disciplined, self-monitored, and self-corrective thinking. It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem-solving abilities, as well as a commitment to overcome our native egocentrism and sociocentrism. (The Critical Thinking Community 2011) Overall critical thinking makes you work on your thinking continuously, to make your thinking the object of every thought, to make your behavior the object of your own thinking; to make your beliefs the object of your thinking. The extent to which any of us develops as a thinker is directly determined by the amount of time we dedicate to our development, the quality of the intellectual practice we engage in, and the depth, or lack thereof, of our commitment to becoming more reasonable, rational, successful persons. Now for is critical thinking apart of science? Yes, it surely is. In the development of critical thinking science can be seen as the ultimate extension. Science entails thrusting ideas together and putting them to the test. The PIE system attempts to broaden the perspective, by placing psychiatric problems in a much broader context of social problems and challenges (Karls & Wandrei, 1994). This is a step forward, as there is some attention to strengths in this model. It cannot be said to come from a strengths perspective, however, which would seem to require a greater transformation and shift of focus. More importantly, this dichotomy is based on the illusory idea of therapeutic neutrality or transparency. That is, it assumes the practitioner has little influence on the experience or presentation of the client. No one is a critical thinker through-and-through, but only to such-and-such a degree, with such-and-such insights and blind spots, subject to such-and-such tendencies towards self-delusion. For this reason, the development of critical thinking skills and dispositions is a life-long endeavor. References: Carey, M. & McCardle, M.

Pre Revolutionary War Attitudes

By the 1750’s, Americans began to query their involvement with the British Empire by establishing their own identity and unity as Americans. The colonist began to see a strong display of British oppression. Taxes and the different Acts, such as the Intolerable Acts caused the colonists to believe that it would be better if they were separated from their mother country. Colonists also felt that some of their rights and liberties were being taken away by the British Empire. By the eve of the revolution colonist had a sense of identity of an American.America became the melting pot of the world. Colonist began to think of themselves as a new race of men (Document H). Colonist slowly dismissed their ancient dispositions and demeanor and accommodated new ones (Document H). With a natural barrier (the ocean) between Great Britain and America, colonist started to think of the colonies as a separate nation (Document B). The ocean caused the colonist to believe that they were separated from the mother land for a reason (Document B). They believed that the ocean was there to prevent the colonies from blending with Great Britain (Document B).Since colonists were separated from Great Britain they considered having their own congress (Document D). The colonist would rather have three thousand people who is living near them and who can see the problems they are facing govern them rather than have one person govern them that isn’t there and doesn’t know what’s going on in the area the colonist are located at (Document D). Another act of identity is show in 1774 and 1775 (Document G). During those years Boston wasn’t relying on Great Britain to provide them with donations of goods, such as food, animals, or money (Document G).This illustrates that the colonies don’t need to confide on Great Britain and they can depend on the other colonies alternatively. Throughout these events it is evident that the colonists are displaying a sense of identity. Before the revolution, the colonist displayed many acts of unity. In 1754, a picture of a cut up snake was posted in the Pennsylvania Gazette (Document A). Benjamin Franklin once said, â€Å"If not united to form a whole snake, then the snake cannot survive†. The picture displayed that if the colonies do not come together as one united nation, it is possible that the different colonies could perish (Document A).This picture could have motivated the colonies to act as one nation. In 1774, it was said that a very small corrupted Junto, a self appointed committee in New York acknowledged the idea that all of North America was united (Document C). The Junto also acknowledged that North America was determined to defend their rights and liberties endlessly against Great Britain (Document C). On July 6, 1775, the representatives of the United Colonies of North America met in Congress at Philadelphia to talk about going to war (Document E).Colonists were daring to start reb ellions and resist their authority to preserve their liberties (Document E). The representatives were under the impression that all the colonist had the same state of mind. They thought that they would rather die as freemen rather than like slaves (Document E). Another unifying act of the colonies was when many of the colonies donated food, animals, money, and etc to Boston in 1774 and 1775 (Document G). The colonies donated goods due to the Intolerable Acts, when the British closed the Boston ports.This illustrates that the colonist were willing to come and work together to help other colonies in need. Throughout these events it is evident that the colonists are displaying a sense of unity. Throughout history there has been many acts of Americans developing a sense of identity and unifying as one nation. Americans were very devoted to making sure they were not taken advantage of by Great Britain. Although Americans had to fight for their independence and their liberties they were a ble to push and break free from the British Empire.

Assessment of the Interactive Behavior Style

According to the DISC Platinum Rule Assessment, the â€Å"Interactive† behavior style defines people who are highly focused on other people. They love being around groups and they are fond of being involved in groups. They are generally extroverts and they do not like to be alone. They love working with other people. And they are very sociable. According to the assessment, people who are â€Å"interactive† get their motivation from being around other people. Their ultimate goal is to get other people’s recognition. They want to earn applause, acceptance, and complements.If recognition from other people is not present, they will ultimately lose their interest in whatever they are doing. Their drive to strive for their goals comes from other people. Most of the time, their ultimate goal is to earn to be appreciated. As for their decision making and their lifestyles, people categorized under the â€Å"interactive† behavior are very fast paced. They do not lik e routines. They are very spontaneous. Because of their liveliness, they usually want to do a lot of things all at the same time. Even if they are still involved with one activity, they jump to another task. That is why they often end up so disorganized.Aside from disliking everyday habitual activities, interactive people also don’t like facts. They do not like details. Instead, they generalize information. They base their conclusions on â€Å"guesstimates† than on highly objective and empirical data. That is why they often exaggerate. Interactive people also work well with others. Because they are sociable, they usually tend to attract the attention of others. They also have the ability to motivate others in order to work towards a common goal that they also pursue. They are perfect for those professions and careers that require excellent rapport with other people.They should be in the field of sales, entertainment, public relations, social welfare, and the like. Appl ication of Strengths and Weaknesses Just like what the assessment states, I am optimistic. I see life as an opportunity to do various activities. I am positive and cheerful. Everyday, my greatest accomplishment seems to stem from fulfilling one or two lively activities. Even if there is really nothing to do outside, I make it a point to go out and to look for something that I can occupy myself with. I love being around other people and that is probably why I value my friends so much.I also like going to parties and other social activities. I make it a point to form new friends despite the fact that I already have many acquaintances. Whenever I go to social gatherings, I make it a point to meet a new friend. I am one of those few people that you cannot alienate even if you expose me to groups of people that I do not know. I am also persuasive and very motivating. I can easily talk my friends into doing something I believe is terrific. In addition to that, I am very enthusiastic. I th ink it is a total waste of time to be lying around and doing nothing.I love engaging in various activities, even those which I am not very familiar with. I am passionate about living life to the fullest. However, because I do love engaging in many activities, I often become careless primarily because I am often preoccupied with so many things all at the same time. This is also probably the reason why I often end up being disorganized. My initially planned schedule for the day often gets tangled with the other activities that I usually want to slip in it. Analysis of the behavior assessment The analysis seems to be quite accurate in describing the prime motivators, strengths, and weaknesses of a person.The data yielded is very useful primarily because it was very thorough in describing the assessed person. It includes the possible conflicts associated with his set of strengths and weaknesses, as well as the possible steps that can be taken to solve such conflicts. The data provided i n the assessment can largely contribute to overall self-improvement. Understanding your tendencies and gaining insight on your personality can improve rapport and communication with other people. It can predict job performance and potential leadership skills (Kierstead, 1998). It can also be used in understanding the personalities of other people.In a personal case, it can help one concentrate on his strengths while altering his weaknesses. However, it should be noted that people should not confine their identities to the discussed test results (Carey,2004). Also, I have noticed that some characteristics of a particular behavior type often overlap some of the traits of the other types. Though the delineation between the types is often very obvious in the initial description, the question of exclusivity between the characteristics can be observed in the specific details of the subtypes of the behavior assessment.Also, although the results of the assessments are quite accurate, it sho uld be noted that people should not confine their self concept with the descriptions provided by behavioral evaluation, no matter how elaborate they are. Regardless of how complete and concise the assessment results are, people should realize that the results were based on a personality evaluation taken during a certain period of time at a certain moment in a person’s life. In simple terms, it is relatively an accurate assessment of someone’s here and now.It should be noted that people are rapidly evolving beings that can radically alter their behavior and personality over time, based on the set of experiences and challenges that come their way. A person with an interactive behavior type can transform into one who has a cautious or dominant behavior after having one of those life changing experiences or major life turn points. Basically, a technical generalization of the personalities of men should not be regarded as the sole indicator of how a person should be interpr eted.It should not be sued as a basis of what kind of people should one get along with. Confining your analysis of people into four types or sixteen subtypes can greatly promote stereotyping. As such, these should not be used as the sole basis of interaction with other people. In order to ascertain the adaptability and the efficiency of this behavior evaluation, such forms of assessments should be taken regularly in order to form comprehensive and accurate concepts of one’s self.

Rivington Hospital Laundry Department Essay Example | Topics and Well Written Essays - 1500 words

Rivington Hospital Laundry Department - Essay Example The existing budget is more than enough to demoralize her. This budget may cause some serious changes in the apparent behaviour of the laundry supervisor as she is not happy and satisfied with the way she has been held responsible for every cost of the laundry department. Different kinds of behaviours can be displayed by the laundry supervisor, the details of some of them are provided below: Quality Compromise The biggest change in the behaviour of the laundry supervisor would be shown in terms of the quality that she provides. After this performance report, her aim and objective would be to cut the cost and meet the targets specified in the budgets, and in doing so, if the quality of laundry service is compromised, she would not focus on it too much. After all, the administrators are more concerned with meeting the budgets, in this way the overall quality of the department may likely be hampered by such move of the administrators. Restricting the Activity Level Since the major cause of adverse variances in the existing budget is the increase in the activity level due to which more laundry services were provided and as a result the level of costs also increased in every manner, including the excessive cost of hiring an additional worker, therefore, the laundry supervisor would try to restrict the activity level to the budget level and may not provide the laundry services to the additional activity level so that the budgeted activity level should not be crossed. In this way, the excessive cost can be reduced which occurred as a result on increasing the actual activity level. This move would surely decrease the overall activity level of the hospital but result in meeting the budgeted costs. Falsification and Misrepresentation The laundry supervisor may also use some negative tactics in order to provide a better picture to the administration by reporting the falsified and misrepresented figures of the activities of the laundry department so that budgets can be ful filled accordingly. This step would cause the likelihood of frauds in the hospital. On a concluding note, if the administration is quite keen in getting the budgets fulfilled by the laundry department, it would have to include the laundry supervisor in budget setting activity so that a unanimous budget can be established which would surely be challenging but at the same time achievable to the laundry supervisor. b) Criterion for Variance Investigation The investigation of variance is undoubtedly an important objective of the organization such that the organization is more interested to find out the root cause of such variances. The variances may be either favorable or adverse in nature. The organization should focus on investigating both types of variances because generally the favorable variances are considered as good and they are not investigated but they have serious negative implications behind them. Managers normally try variances to be more favorable because in this way their performance would be marked high and they would be appraised on a better note. But on the other side of the picture, the favorable variances are pulled out deliberately by those managers such as hiring the low-skilled workers or even unskilled workers and purchasing the poor quality raw material etc. In this way, the favorable variances leave negative impacts and harm the overall organizational goals. The overall criteria to examine the variances should be based on the nature and

Emotional and Physical Symptoms of Depression during Pregnancy And Essay

Emotional and Physical Symptoms of Depression during Pregnancy And Different Ways of Treatment 2 - Essay Example In one year, it would be possible to have a favorable sample size. The responsibility of the nurses handling antenatal care is critical in the research, because they would be in charge of patient enrollment and diagnostic procedures. Pregnant women that meet the criterion described in the DSM manual of depression would form the eligible group. Moreover, the research would also consider the treatment strategies used to address the cases, and eventually compare the effectiveness of the strategies. On larger scale, the research would involve the collection of data from different health centers (Kothari, 2005).   After identifying the different treatment strategies used to treat pregnant mothers that suffer depression, a qualitative research on the efficiency of each would follow (p. 56). This would mean that different patients would receive different therapies, and a close monitoring of each would follow. In a bid to determine the most effective strategy, the research would consider the time taken by patients to heal, and aspects of their emotional health after the depression. This research would produce evidence-based results on the most effective treatment. It is important to determine the prevalence of emotional depression during pregnancy. Therefore, the number of patients presenting symptoms in different health centers would be considered for a period of one year. Statistical analysis of the data obtained would help in determining the prevalence of depression in pregnancy. Evidently, the selection of an effective methodology is one of the critical aspects of consideration prior to carrying any research. The selected methodology selected determines the data collected, and hence the findings. As highlighted above, there are different facets of this research, necessitating both quantitative and qualitative researchers. This will help in determining the physical and emotional symptoms of depression in pregnant women. Moreover, the above

Development of English as a Global Language Essay

Development of English as a Global Language - Essay Example "Standard English" is a general term for a form of written and spoken English that is considered the model for educated people. There are no set rules or vocabulary for "standard English" because, unlike languages such as French, English does not have a governing body that establishes official usage. The concept of "standard English" is therefore fluid. ELFE stands for "English as a lingua franca for Europe." It is promoted by some linguistics experts, and aims to standardise the use of the English language in the European Union. RP, as in "British RP," is short for "Received Pronunciation" - received from the Queen or King, as it were. It is sometimes defined as the "educated spoken English of south-eastern England." RP is itself sometimes called the Queen's English, which stands to reason, but the Queen's English is sometimes even defined as "the language of the United Kingdom." RP was sometimes referred to as "BBC English," since this was the traditional pronunciation to be heard on the BBC, but RP is not often called "BBC English" any more-as a result of the multitude of accents heard on the BBC these days. "Oxford English" is simply the dialect of English spoken at Oxford University. Some consider Oxford English the most standardised, and sometimes even as synonymous with "Standard English," whereas others consider it pompous and pretentious. Standard English: http://en.wikipedia.org/wiki/Standard_English RP: www.infowrangler.com/phpwiki/wiki.phtmltitle=Received_Pronounciation BBC English: http://en.wikipedia.org/wiki/Received_pronunciation Oxford English: Wikipedia. The rest of the information is something that I know. Official versus Global Status How does one language achieve such a status First, the using of language is a social act (Cameron, 1995); language is the means of communication. It follows that social change will contribute to a change in status of a language, as Knowles implies in his study of the history of the English language (Knowles, 1997). Next, that medium can become the official language (as distinguished from global) of a country when it is adopted (and adapted) as the mother tongue and used by "such domains as government, the law courts, media, and the educational system [of that country]" (Crystal, 2003, p.4). Finally, language achieves a genuinely global status as it "develops a specific role that is recognised in every country" (Crystal, 2003, p.3). English, however, did not achieve global status by way of one or two variables. Several factors contributed to the process and arrival of English as a global language. These factors are part of a slowly evolving phenomenon that parallel the social changes experienced by numerous cultures over many eras. Social Changes as Influences Political, military, economic, cultural, scientific and technological changes in society propelled the English language towards the historically significant status of "global language," since no other language has ever laid stake to so grand a claim. 1. Emigration and Invasion The Old Saxon language (also called Old Low German) and related dialects influenced Germanic populations. Germanic peoples from the coast of Frisia, Lower Saxony, Jutland and Southern Sweden emigrated to Britain during the Roman occupation of Britain, lasting,

Management of Technology3 Essay Example | Topics and Well Written Essays - 250 words

Management of Technology3 - Essay Example It is worth noting that the two business processes get interlinked by IT. There are several BI systems that an organization can put in place. These include analyzing customers’ behavior, budgeting and financing as well as improving delivery and supply chain effectiveness. These BI systems can help an organization reduce the cost of production, improve performance and identify new markets within the economy. BI systems require an analysis that will best help the organization remain relevant in the market (Laudon & Laudon, 2013). They are, therefore, part of the plan of every organization that aims to excel in its field. An organization may offer an electronic feedback program to its customers as one of their electronic business programs. This program can help the organization identify the area that it ought to improve on in terms of its services (Laudon & Laudon, 2013). The program can also be used to rate the quality of the goods produced by the company. The organization can further use the electronic registration of goods bought by customers for those goods that require registration with the government upon buying. This can be used instead of buying goods and then going to register them somewhere

Rape in the Military II Essay Example | Topics and Well Written Essays - 750 words

Rape in the Military II - Essay Example Investigating and reporting The Sexual Assault Training Oversight and Prevention Act (STOP Act) to be implemented soon proposes to take the responsibility of investigation and reporting of sexual assaults outside the purview of regular chain of command of the military and bring them under the jurisdiction of an autonomous office manned by civil and military experts. The Bill H.R.3435 moved by Congress Woman Speier Jackie is currently under the consideration of the Subcommittee on Military Personnel (Speier, n.d.). Response to victims It has been suggested that women victims should not remain silent about sexual assaults on them and they should approach and report the assault to MPs, JG, JAG, EEO and Civilian authorities and not to stop until someone takes up the cause. Best way is to file complaint with local and military police without delay and ensure that complaint is made to outside the military channels. Military on its part should be compassionate towards the victims. They shou ld consider the cases individually without assuming all women are liars and avoid prejudgment. The victims or witnesses should not be punished for reporting sexual assaults. It should be the policy to separate the victim and offender by sending the offender to a different unit. The transfer of the offender to another unit only transfers the problem to another unit or if the offender is discharged, then the problem is dumped on the society (Nelson, 2002). As such the offender should undergo reformation before he is released to the society or transferred to another unit. Confidential counseling The rape victims should be offered confidential rape counseling but they should not be compelled. Survey results suggest that counseling as the most appropriate way of helping the rape victims. Importantly, the offer of counseling should be made immediately and the counseling should be done by an expert trained and experienced in sexual trauma problems. In case non- availability of counselors o n the campus, prompt referrals should be made to outside experts who would include civilian counselors also. The first responders to the rape reporting such as commanders, hospital staff and the military police should be adequately apprised of the need for prompt and appropriate referrals. Though confidentiality is essential, Privacy Act 1974 exempts officers and employees to have access to the information so that they can decide on the victim’s fitness for military duty. The victims should be encouraged to talk freely to an expert who is not connected to the case. Rape victims may be referred to veteran center or civilian health facility and not to military mental health clinic. The rape victims are comfortable with a female supervisor who will not hesitate to take positive course of action. Every chain of command should have an EEO position since victims complain that male officers do not listen to them at all. The recommendations should include that investigators should â €Å"quit concentrating â€Å"90 % of the victims’ genuineness and 10 % on the offender. Multiple complaints on the same offender should be relied up on as a valid evidence of the assailant’s character. It has been suggested that these crimes should be prosecuted in accordance with the current laws and regulations. The victim should be provided with a legal representative. Written transcripts of all hearings should be supplied to victims. Under no circumstances, should victims be charged with. Intervention between

Explain the process by which democracy was accepted as a valid form of government Essay Example for Free

Explain the process by which democracy was accepted as a valid form of government Essay Democracy denotes to a government by the people. The name comes from the Greek and means â€Å"rule by the people. † Democracy is government by the majority of the people, or majority rule. It differs from monarchy (â€Å"rule by one†), aristocracy (â€Å"rule by the best, or nobles†), and oligarchy (â€Å"rule by a few†). Democracy has three different related meanings: (1) a form of government in which those who control the government are elected by the people and are responsible, or answerable, for their actions to the people; (2) a form of society in which there is no privileged class and in which individuals may rise by ability to positions of power and influence; and (3) an ideal or way of life that stresses equality, liberty, individual rights, tolerance, freedom of discussion, and compromise. Most democracies are republics, in which the people elect the head of the state. A monarchy with a hereditary king or queen may also be democratic. In Great Britain, for example, is a democracy in the form of a limited monarchy. Some countries that call themselves republics are not democracies. A country with a republican constitution may be a dictatorship in which government is under the complete control of one person. On the other hand, republic is a country in which both the head of the state and the members of the legislature are elected directly or indirectly by the people. Most of the nations of the world today, including the United States and the Soviet Union, are republics. The rest, in most instances, are monarchies, in which the head of the state (a king, queen, or prince) comes into office through inheritance. The term republic and government are sometimes confused. Republic means a constitutional form of government under which the head of the state is elected, either by direct popular vote or indirectly through elected representatives. In addition, social contract denotes to human race originally lived in a â€Å"state of nature,† in which people enjoyed complete freedom, with no laws and no government. Without constraints on their activities, however, people were constantly fighting among themselves, and the safety of each individual was endangered. To ensure their survival, people eventually made an agreement called a social contract, to establish a system a law and order. On the other hand, balance of power is relatively equal distribution of economic and military strength among rival countries or groups countries. For 400 years, the countries of Europe devoted much of their diplomatic and military effort to creating or maintaining such a balance. Their object was to prevent any single nation or group of nations from becoming powerful enough to dominate the continent. The idea of maintaining power equilibrium became an important influence in European politics in the 16th century. An outstanding example of balance-of-power politics occurred in the Thirty Years’ War (1618-48). Furthermore, Republican Party is one of the two major political parties in the United States. Since the time of the Taft administration (1909-13) it has generally been regarded as more conservative than the other major party, the Democratic. However, this difference between the two parties has not always been sharp, as the Republican Party initiated or supported progressive legislation. Also, the Republican Party, like the Democratic, has both liberal and conservative factions. Nonetheless, the Republican Party is generally associated with the interests of business, the wealthy and propertied, and those opposed to the ideas of the welfare state and a â€Å"big government. †

A Major Application Area Of Thermodynamics Engineering Essay

A Major Application Area Of Thermodynamics Engineering Essay A major application area of thermodynamics is refrigeration, which is the transfer of heat from lower temperature region to a higher temperature one. The devices that produce refrigeration are called refrigerators, and the cycles on which they operate are called refrigeration cycles. The most frequently used refrigeration cycle is a vapour-compression refrigeration cycle in which the refrigerant is vaporized and compressed alternatively and is compressed in the vapour phase. There are number of refrigerants which can be used in here, but the most commonly used on a commercial scale is a R12 (used in this experiment as well). The thermodynamics of ideal vapour compression cycle can be analyzed on a temperature versus entropy diagram as depicted in Figure 1. At point 1 in the diagram, the circulating refrigerant en- ters the compressor as a saturated vapour. From point 1 to point 2, the vapour is isentropically compressed (i.e., compressed at constant entropy) and exits the compressor as a superheated va- pour. From point 2 to point 3, the superheated vapour travels through part of the condenser which removes the superheat by cooling the vapour. Between point 3 and point 4, the vapour travels through the remainder of the condenser and is condensed into a saturated liquid. The condensation process occurs at essentially constant pressure. Between points 4 and 5, the saturated liquid refrigerant passes through the expansion valve (throttling device) and undergoes an abrupt decrease of pressure. This process results in the adia- batic flash evaporation and auto-refrigeration of a portion of the liquid (typically, less than half of the liquid flashes). The adiabatic flash evaporation process is isenthalpic (i.e., occurs at con- stant enthalpy). Figure 12 Temperature Entropy diagram 1 www. wikipedia.org/wiki/Refrigeration 2 http://upload.wikimedia.org/wikipedia/commons/f/f7/RefrigerationTS.png UMAR DARAZ Page 3 of 22 Thermodynamics Lab 2 Between points 5 and 1, the cold and partially vaporized refrigerant travels through the coil or tubes in the evaporator where it is totally vaporized by the warm air (from the space being refrigerated) that a fan circulates across the coil or tubes in the evaporator. The evaporator operates at essentially constant pressure. The resulting saturated refrigerant vapour returns to the compressor inlet at point 1 to complete the thermodynamic cycle. The area under the process curve on T-s diagram represents the heat transfer for internally reversible processes. The area under the process curve 5-1 represents the heat absorption in the evaporator, the area under the process 2- 4 represents the heat rejection in the condenser. In the ideal vapour compression refrigeration cycle all the heat losses and disruptions are being ignored, but in actual refrigeration cycle, we need to take these losses into consideration as they have been mentioned in this report later. The Hilton refrigeration laboratory unit R714 is capable of following entities;  · Investigation of the variation in refrigerator duty or cooling ability for various condens- ing temperature and the heat delivered to the cooling water with variation in condensing temperature. We can also investigate the variation in refrigeration coefficient of per- formance for the various condensing temperature.  · Investigation of the variation in coefficient of performance based on electrical, shaft and indicated power, determination of the overall heat transfer coefficient for the condenser cooling coil and performance of the thermostatic expansion valve.  · Investigation of the heat delivered to the cooling water with variation in condensing tem- perature, coefficient of performance as a heat pump for various condensing temperature, as well as power input based on electrical, shaft and indicated power. The important aspect of this report is to demonstrate the two laws of thermodynamics i.e. first and second law of thermodynamics. The first law is simply an expression of the conservation of energy principle, and it asserts that energy is thermodynamic property. Qout = Wnet + Qin Equation (1) In this experiment the Qin is provided by input voltage, this input is used to do the net work done on the refrigerant by compressor and motor, and the result of this produces the heat which is being removed by the condenser i.e. Qout. The second law of thermodynamics asserts that energy has quality and quantity, and actual processes occur in the direction of decreasing quality of energy. UMAR DARAZ Page 4 of 22 Thermodynamics Lab 2 Aims and objectives: The Hilton refrigeration laboratory unit R712 has been designed to allow students to fully investigate the performance of a vapour compression cycle under various conditions of evaporator load and condenser pressure. The main objectives of this laboratory are listed below;  · The demonstration of application of the First and second law of thermodynamics.  · The introduction of to refrigeration plant and calculate the various coefficient of perform- ance.  · Investigation of system losses, this includes motor, compressor, evaporator and con- denser losses. These losses (friction, heat losses) occur only in practical/commercial refrigerator, there are no losses in ideal vapour compressor refrigerator. UMAR DARAZ Page 5 of 22 Thermodynamics Lab 2 Apparatus The figure shown below looks like a refrigeration laboratory unit R712 (not exactly it) and it consists of the following components; Figure 23 Refrigeration laboratory unit Panel: High quality glass reinforced plastic on which the following components are mounted. Refrigerant: R12 Digital Thermometer: A device that measures temperature. Wattmeter: Allows measurement of the power input to either evaporator or motor. Voltage Controller: To vary evaporator load. Variable Area Flow meters: Variable area types to indicator R12 and H2O flow rates. Pressure Gauges: To indicate R12 pressure in evaporator and condenser. Spring Balance and Tachometer: These two together allow measurement of power required to drive the compressor. Expansion Valve: Thermostatically controlled type i.e. throttling device. Evaporator: Electrically heated device i.e. heat exchanger Compressor: (Internally mounted) Twin cylinder belt driven unit, along with spring balance force system. Condenser: A device or unit used to condense vapor into liquid. It is also called heat exchanger. Motor: A machine that converts electricity into a mechanical motion. 3 www.p-a-hilton.co.uk/English/Products/ Refrigeration__2_/refrigeration__2_.html UMAR DARAZ Page 6 of 22 Thermodynamics Lab 2 Procedure4 In prior performing an experiment the most important things to do are, to measure the atmos- pheric pressure, which would be added to the gauge pressure to get an absolute pressure for both condenser and evaporator, and to balance the two tips of the spring balance force, being applied on the compressor. In failure to do these things would cause a sufficient amount of error in the final results. In this experiment the condenser pressure is being kept constant i.e. 900KPa. Step-1 Turn on the refrigeration plant using one of the control breakers, and setting the evaporator voltage i.e. 40 100 volts, at the same time balancing the two tips of compressor load and set the condenser pressure to 900KPa, using rota-meter. Step-2 Record the following values; Evaporator Amps (1-2.42A), from wattmeter, compressor speed using tachometer, water and refrigerant flow rate using flow meter. Step-3 Record the spring balance force, reading directly from the scale. The hot water is in the tubes is indicated by red and cold water is indicated by blue sign in the refrigeration plant. Step-4 The flow rate is controlled by a throttling device (valve), the small changes in opening and closing the valve, effect the condenser pressure. Step-5 The temperature values of the refrigerant at different stages in the whole cycle at constant pressure is given by temperature dialler. Now we had all the values we needed, now we changed evaporator Amps value, recorded rest of the values as mentioned earlier and repeated the whole experiment for three to four times. The Refrigeration Laboratory Unit has three controls. Firstly a combined miniature circuit breaker and switch turns on both the compressor motor and the supply to the electrically heated evaporator. A combined variable area water flow meter and valve allow control of the condenser pressure and a panel mounted voltage controller allows control of the evaporator load from zero to full power. Refrigerant R12 vapour is drawn into the compressor from the evaporator mounted on the front of the panel. Work is done on the gas in the compressor and its pressure and temperature are raised. This hot, high pressure gas discharges from the compressor and flows into the panel mounted water cooled condenser, where heat is removed from it. This liquid then flows through a thermostatic expansion valve. Here it passes through a controlled orifice, which allows its pressure to fall from that of the condenser to that of the evaporator. The refrigerant has a satu- rated vapour phase at this point. The voltage across the heater elements may be varied from zero to that of the mains supply voltage by adjustment of a voltage controller situated on the front panel.

Calculations To find absolute pressure, we need an atmospheric and gauge pressure of the component. Now for two individual components,  · Condenser As we know Patm = à Ã‚ gh = 13600 kg/m3 ÃÆ'- 9.81 m/s2 ÃÆ'- 762 ÃÆ'-10-3m = 101.663ÃÆ'-103 Kg / ms2 = 101.663 KN/m2 Hence Pgauge,cond = 900 KN/m2 Pabs,cond = Patm + Pgauge,cond = 101.663 + 900 = 1001.663 KN/m2  · Evaporator As Patm = à Ã‚ gh = 13600 kg/m3 ÃÆ'- 9.81 m/s2 ÃÆ'- 762 ÃÆ'-10-3m = 101.663ÃÆ'-103 Kg / ms2 = 101.663 KN/m2 i. Pgauge,Evap = -20 KN/m2 Pabs,Evap = Patm + Pgauge,Evap Therefore = 101.663 + (-20)= 81.663 KN/m2 ii. Pgauge,Evap = 20 KN/m2 Pabs,Evap = Patm + Pgauge,Evap = 101.663 + (20)= 121.663 KN/m2 iii. Pgauge,Evap = 40 KN/m2 Pabs,Evap = Patm + Pgauge,Evap Therefore = 101.663 + 40 = 141.663 KN/m2 To find Qw (Heat removal from condenser) As we repeated the experiment three times, so water flow rate have three different values, hence we need to find Qw at three points, Qw = Mw ÃÆ'- 4.18 (t6 t5) When Mw = 1.5 gs-1, t6 = 41.2 0C, t5 = 23.8 0C Qw = 1.5 ÃÆ'-4.18 (41.2 23.8) = 109.098 W UMAR DARAZ Page 11 of 22 Thermodynamics Lab 2 As Qw = Mw ÃÆ'- 4.18 (t6 t5) When Mw = 5.0 gs-1, t6 = 39.6 0C, t5 = 21.6 0C So Qw = 5.0 ÃÆ'-4.18 (39.6 21.6) = 376.2 W Qw = Mw ÃÆ'- 4.18 (t6 t5) When Mw = 6.0 gs-1, t6 = 38.5 0C, t5 = 21.4 0C Qw = 6.0 ÃÆ'-4.18 (38.5 21.4) = 428.87 W To find Wc (work done by the compressor or a shaft loss) The work done by the compressor depends on spring balance force and motor speed, hence to get more work done out of the compressor we need to increase any of the above mentioned parameters. Therefore Wc = 0.0172ÃÆ'-FÃÆ'-Nm i. Wc = 0.0172ÃÆ'-5.5ÃÆ'-1512.09 = 143.043 W ii. Wc = 0.0172ÃÆ'-7.5ÃÆ'-1502.58 = 193.832 W iii. Wc = 0.0172ÃÆ'-8.2ÃÆ'-1449.71 = 204.467 W To find Wm (work done by the motor on a shaft to rotate) The work done by the motor is a product of voltage provided, amount of current flowing the motor and power factor of the shaft, which gives us the following values; Wm = Vm ÃÆ'- Im ÃÆ'- pf i. Wm = 235 ÃÆ'- 3.6 ÃÆ'- 0.43 = 363.78 ii. Wm = 232 ÃÆ'- 3.6 ÃÆ'- 0.48 = 400.89 iii. Wm = 232 ÃÆ'- 3.6 ÃÆ'- 0.52 = 434.31 UMAR DARAZ Page 12 of 22 Thermodynamics Lab 2 To find CoPnet (Total coefficient of performance of refrigerant) CoPnet = Qe, Elec / Wm By substituting different values of electric input heat energy (artificial input energy) and the work done by the motor, we get net coefficient of performance of the cycle, i. CoPnet = 40 / 363.78 = 0.109 = 11% ii. CoPnet = 119 / 400.89 = 0.296 = 30% iii. CoPnet = 242 / 434.31 = 0.557 = 56% To find CoP (te-t2) This is the coefficient of performance of ratio of temperature values at point 1-4 and difference of it, to the temperature of the refrigerant after compression, so we get following CoP (te-t2) = t41 / (t2-t41) i. CoP (te-t2) = 13.9 / (69.4 13.9) = 0.250 = 25% ii. CoP (te-t2) = 8.5 / (59.9 8.5) = 0.165 = 16% iii. CoP (te-t2) = 1.0 / (68.5 1.0) = 0.015 = 1.5% To find Qe, R 12(Heat removal from Evaporator) The given equation is à ¢Ã¢â€š ¬Ã‚ ¦ Qe, R 12 = Mr (h1 h4) By substituting different values of enthalpy, which we recorded from a pressure enthalpy diagram, so we get i. Qe, R 12 = 0.7 (340 160) = 126.0 ii. Qe, R 12 = 1.5 (345 170) = 262.5 iii. Qe, R 12 = 1.9 (360 180) = 342.0 UMAR DARAZ Page 13 of 22 Thermodynamics Lab 2 To find Wc (Input work done or compressor work loss) The input work done by the compressor can be calculated by finding flow rate of the refrigerant R12 and the difference of enthalpy of refrigerant before and after the compression. Wc = Mr (h2 h1) Substituting all three values of the above parameters (variables), we get i. Wc = 0.7 (385 340) = 31.5 ii. Wc = 1.5 (400 345) = 82.5 iii. Wc = 1.9 (420 360) = 114 To find Q cond (Heat loss by the condenser) Similarly heat loss by the condenser is a product of refrigerant flow rate to the difference of enthalpy values of it, before entering and leaving the condenser, we get Q cond = Mr (h2 h3) Now, using above stated equationà ¢Ã¢â€š ¬Ã‚ ¦ i. Q cond = 0.7 (385 225) = 112 ii. Q cond = 1.5 (400 240) = 240 iii. Q cond = 1.9 (420 250) = 323 To find CoPR12 (Coefficient of performance of refrigerant) CoP R12 = (h1 h4)/(h2 h1) Coefficient of performance of refrigerant is a ratio of all the enthalpy values in the cycle, here note that for ideal vapour compression refrigeration cycle h3 = h4 Hence we get i. CoP R12 = (340 160) / (385 340) = 4.00 ii. CoP R12 = (345 170) / (400 345) = 3.1818 iii. CoP R12 = (360 180) / (420 360) = 3.00 UMAR DARAZ Page 14 of 22 Thermodynamics Lab 2 Systems losses Motor loss = Wc Wm = 143.043 363.78 = -220.75 = 193.832 400.89 = -207.06 = 204.467 434.31 = -229.84 Compressor loss = Wc-Wc = 31.5 143.043 = -111.54 = 82.5 -193.832 = -110.33 = 114 204.467 = -90.47 System loss = Qcond Qw = 112 109.09 = 2.91 = 240 376.20 = -136.20 = 323 428.87 = -105.87 System loss = Qe, R12 Qe,Elec = 126 40 = 86.00 = 262.5 119 = 143.50 = 342 242 = 100.00 UMAR DARAZ Page 15 of 22 Thermodynamics Lab 2 Discussion of Results The observation table of results has been listed on page 8 9, and it is followed by all the calculations required to complete the table or to get the results. The experiment has been repeated three times, so all the results (values have been listed three times. In the calculation section the system losses and heat energy are shown as negative val- ues, its because the work is done on the system and heat is being removed from that particu- lar system, in this case its condenser. The positive values of system loss and heat energy shows that heat is being add in the system and work is done by the system, and in this case its evaporator. The condenser pressure i.e.900 KPa, was not exactly 900 KPa. As we were set- ting the pressure manually, so in the whole experiment the pressure was 900 KPa  ± 10%, it was because of the fluctuation in the gauge needle, so we assumed the considered pressure. The compressor pressure applied by spring balance force, affected the work done of the com- pressor on the refrigerant R12, because to get an accurate compressor work done, the two tips of the spring balance should be in balance (level), but during an experiment we were getting random values (results), so then I realised that something is wrong, so I looked at all the components of the refrigeration plant, and I found that the two tips of the spring were not bal- ance. Hence to get right results we had to redo the experiment. The throttling device or valve has a huge impact on condenser pressure, because by opening or closing i.e. changing a flow rate make a considerable amount of difference on condenser pressure and evaporator tem- perature. Motor loss refers to the consumption of electrical energy not converted to useful mechanical energy output, but in this case energy loss means less input energy to the compressor, which means a refrigerant would be less compressed by a compressor, so less heat would be re- moved by the condenser, and even after passing through the valve the refrigerant would still have a high temperature and pressure, hence less refrigeration would occur in a vapour com- pression cycle. Therefore we need to take into account power losses in the electric motor. In order to study this process more closely, refrigeration engineers use this pressure en- thalpy diagram shown in Figure 5. This diagram is a way of describing the liquid and gas phase of a substance. Enthalpy can be thought of as the quantity of heat in a given quantity, or mass of substance. The curved line is called the saturation curve and it defines the boundary of pure liquid and pure gas, or vapour. In the region marked vapour, its pure va- pour. In the region its marked liquid, it is a pure liquid. If the pressure rises so that we are considering a region above the top of the curve, there is no distinction between liquid and va- pour. Above this pressure the gas cannot be liquefied. This is called the Critical Pressure. In the region underneath the curve, there is a mixture of liquid and vapour.

So we go straight from that temperature of left side of the doom (saturated liquid) to the right side of the doom (saturated vapour line), and then following the temperature gradient line, we go down and record the enthalpy value at that temperature and pressure. Similarly for the stage 2, we find h2 on x-axis. When the refrigerant leaves the condenser, it obtains a saturated liquid phase (left side of the doom), so taking the reference of condenser pressure line (red line), we take a straight line parallel to the y-axis, and wherever it meets the x-axis gives a value of enthalpy (h3) at stage three. In actual refrigerant plant, enthalpy at stage 3 and stage 4 is not same, but for the sake of calculation we assume that its an ideal condition and enthalpy at these two points is same. Test 1 As Compressor suction = t1 = -23.5 0C and condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h1 = 340 KJ/Kg Compressor delivery = t2 = 59.9 0C and Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h2 = 385 KJ/Kg Here Liquid leaving condenser = t3 = 31.6 0C And Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h3 = 225 KJ/Kg As mentioned earlier that h3 = h4 (Ideal condition) Hence the enthalpy h4 = 225 KJ/Kg But using temperature at evaporator inlet, t4 = -32 0C, we get Actual enthalpy value, h4 = 160 KJ/Kg Test 2 As Compressor suction = t1 = -22.6 0C and condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h1 = 345 KJ/Kg (from above p-h diagram) Compressor delivery = t2 = 68.5 0C and Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence using Figure 4, we get enthalpy h2 = 400 KJ/Kg Here Liquid leaving condenser = t3 = 34.8 0C And Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h3 = 240 KJ/Kg UMAR DARAZ Page 18 of 22 Thermodynamics Lab 2 As mentioned earlier that h3 = h4 (Ideal condition) Hence the enthalpy h4 = 240 KJ/Kg But using temperature at evaporator inlet, t4 = -23.6 0C, we get Actual enthalpy value using figure 4, h4 = 170 KJ/Kg Test 3 As Compressor suction = t1 = -5.2 0C and condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h1 = 360 KJ/Kg Compressor delivery = t2 = 69.4 0C and Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h2 = 420 KJ/Kg Here Liquid leaving condenser = t3 = 33.8 0C And Condenser Pressure (Abs) = Pc = 1001.663 KNm-2, Evaporator Pressure = 40 KPa Hence the enthalpy h3 = 250 KJ/Kg As mentioned earlier that h3 = h4 (Ideal condition) Hence the enthalpy h4 = 250 KJ/Kg But using temperature at evaporator inlet, t4 = -19.1 0C, we get Actual enthalpy value at this stage, h4 = 180 KJ/Kg 6However the expansion of the high pressure liquid, process 5 1 above is non reversible. Notice that Expansion is a constant enthalpy process. It is drawn as a vertical line on the P-h diagram. No heat is absorbed or rejected during this expansion, the liquid just passes through a valve, like water coming out of a tap. The difference is that because the liquid is saturated at the start of expansion by the end of the process it is partly vapour. Point 1 is inside the curve and not on the curve as described in the Evaporation process. At point 4 it starts to condense and this continues until point 5 when all the vapour has turned into liquid. Point 5 is saturated liquid. If more heat is removed, the liquid cools. It is then called sub-cooled liquid. Hence h4 is on a saturated liquid line (left side of the doom), and does not appear in a vapour compression cycle, and this is the case in all three tests. 6 http://www.alephzero.co.uk/ref/vapcom.htm#ph UMAR DARAZ Page 19 of 22 Thermodynamics Lab 2 As there is no moving part in the whole refrigeration plant apart from motor shaft of a compressor, so work done by them is zero, i.e. w = 0 So using steady state energy equation, we get W Q = h2 h1 Equation (2) As W =0, so equation (1) becomes Q = h2 h1 Or Q = h1 h2 Equation (3) The coefficient of performance or COP (sometimes CP), of a heat pump (i.e. refrigerator) is the ratio of the change in heat at the output (the heat reservoir of interest) to the supplied work.To find Cop value of refrigeration plant as well as for the refrigerant is a good practice, because this will illustrate that how much efficient of these two are. 7It takes a lot of heat to evaporate liquid. In other words a small amount of liquid circulating in a refrigerator can perform a large amount of cooling. This is one reason why the vapour compression cycle is widely used. The refrigeration system can be small and compact. Also from a practical point of view heat exchange is much better when using change of state evaporation and condensation. However the expansion of the high pressure liquid, process 5 1 above is non reversible. And so the efficiency of this cycle can never even approach Carnot efficiency. 7 http://www.alephzero.co.uk/ref/practcop.htm UMAR DARAZ Page 20 of 22 Thermodynamics Lab 2 Conclusion 8The vapour-compression cycle is used in most household refrigerators as well as in many large commercial and industrial refrigeration systems but the efficiency of this cycle can never even approach Carnot efficiency, because of its low coefficient of performance. In the refrigeration plant the operating parameters can be varied by adjustment of condenser cooling water flow and electrically heated evaporator supply voltage. Components have a low thermal mass resulting in immediate response to control variations and rapid stabilisation. Instrumentation includes all relevant temperatures, condenser pressure, evaporator pressure, refrigerant and cooling water flow rates, evaporator and motor power, motor torque and com- pressor speed. The most of components of refrigeration plant used in this experiment (R712) are manually calibrated scales (not digital), and based on this poor calibration all the recorded results are being guessed on the base of individual judgment, which is wrong most of the time. Anyway a small amount of liquid circulating in a refrigerator can perform a large amount of cooling. This is one reason why the vapour compression cycle is widely used. The enthalpy values which are being recorded directly from enthalpy pressure diagram (Figure 4), and based on how unclear that diagram is, I would say it is not a great source of information, but still we use this to find enthalpy. The system (refrigeration plant) has some losses, which have described earlier in this report, this includes motor loss, condenser and evaporator loss. In conclusion, I would like to say that by doing this experiment I learnt a great amount of knowledge, about refrigeration plant, and how it works, what kind of cycle more often use for this, how much efficient is this and how to calculate the different losses in this system. I would say by understanding the operation of this small scale refrigeration plant, I think I would be able to operate on an industrial scale refrigeration plant, because the basic principle is same. 8 http://www.alephzero.co.uk/ref/vapcomcyc.htm UMAR DARAZ Page 21 of 22 Thermodynamics Lab 2
