Jeff and Ham essays

Jeff and Ham essays Jeffersonians and Hamiltonians had differing philosophies on the key issues of the late 18th century. These issues included the political opinions on how to pay off the debt, if the United States should have a bank, how we should deal with the French Revolution, and lastly the question of who should govern the country. There were many different thoughts on how the United States should deal with the issue of the nations debt. Hamiltonians, the wealthy Federalist Party, felt that there were two steps to take in funding the debt. The first step was funding at par, which meant that the federal government would pay off its debts at face value, plus accumulated interest. The second step was assumption; this was when Congress would assume the debts of the states. Hamiltonians believed that assumption was a good idea because it would tie the states closer to the federal government, making them depend on it. The Jeffersonians on the other hand did not exactly feel the same way about these philosophies. They did agree with funding at par, but were hesitant towards the policy of assumption. The Jeffersonians were the common people of the country who supported states rights, and they did not think that it was fair that the national government assume the state debt. They felt that some states had alr eady paid off their war debt, and that it was not righteous to assume them more debt. The two parties also had differing views on economic strategies on paying to run the government and the interest on the huge debt. The Hamiltonians thought that we should pay for them by a whiskey excise tax and a protective tariff. They believed that the Constitution stated that the Congress had the power to lay and collect taxes to pay the debts for the welfare of the United States. The Jeffersonians did not feel the same way about these taxes. They opposed the whiskey tax because they considered whiskey to be a necessity and not a luxur...

New Australian National Nurses Registration Research Paper

New Australian National Nurses Registration - Research Paper Example This new registration system has been enacted through relevant education in each State. This new law oversees the administrative aspects of several health professional groups into one national entity. There are many good reasons to make the change and yet there are also many issues that need to be resolved. Nursing in Australia has been mostly a two tiered structure in which there are level one nurses who have a bachelor degree and level two nurses who have extended their education to receive certificate or diploma. Nurses have been the driving force of the healthcare system in Australia. The system is changing with the needs that have been created with the shortage of nurses and the ageing of the present nursing population. This paper will discuss that change. In 1984, the Commonwealth government made a decision to transfer nursing education to tertiary education with level one nurses prepared at the diploma level. In 1992, it became necessary to have a bachelor's degree (Kenny & Duckett, 2004). The Project 2000 report resulted in the change of second level RN training everywhere but Australia. Australia chose not to do this based on the fact that Australia has stronger unions and different strategies for their professional nurses, such as viewing the second level RN as an associate to the RN. This nurse is called the Enrolled Nurse. These EN's are meant to practice under the direction of the level one nurse or RN (professional nurse). They report to the level one nurse but are still responsible for their own practice (Kenny et.al. 2004). Core competencies for the EN have been difficult to monitor as they have been different according to where one works. In some states they have been able to administer medicines and in some states not. The new law which took place July 1, 2010 creates the National Registration and Accreditation Scheme for health care practitioners, including nurses and midwives. This new law will create many changes in the way that healthcare is delivered in Australia, in particular, in the rural areas (Forsythe, 2009). It also creates standardization in licensing and in competency levels. It assures the understanding of the RN level of nursing which is University level, the EN which is diploma level and the NP or nurse practitioner level. III. Bodyiii.i Scope of Practice There are three essential criteria that are noted for defining scope of practice. Those are education, competency, and authorization to practice. These guidelines are published under the ANMB-codes and guidelines in Australia. These guidelines give the nurse and organized process in determining whether something that needs to be done is within her scope of practice. Failure to understand these guidelines can lead the new RN to

Psychological support for breast cancer women and mastectomy Essay

Psychological support for breast cancer women and mastectomy - Essay Example Addie Gilbert, 51, saw the final straw while trying on her favorite red dress whose front was adorned with stylish criss-cross straps, thinking she might never have to wear it again. Following her mastectomy, the heavy prosthesis underneath was clearly visible. She said, â€Å"I was so depressed that I sat on the floor of my bedroom and cut the dress up into little pieces with scissors† (Boughton, 2000). After her mastectomy, she was not only worried about her inability to wear her favorite clothes in the future, but was also troubled by the trauma brought about by the diagnosis of breast cancer every time she saw her reflection and the scar over her chest in the mirror. Gilbert thus decided to have her breast reconstructed. Her breast was molded by taking skin and tissue from her abdomen. Addition of an areola and nipple three months later with an office procedure made her whole again. Different women respond to the surgery of breast cancer in different ways depending upon th eir psychology, self-perception, age, and whether or not the surgery is accompanied by such adjuvant therapeutic procedures as chemotherapy and radiation. Mastectomy can be hard to come to terms with for women like Gilbert, though it is an acceptable alternative for many other patient of breast cancer. Women undergoing surgery for breast cancer commonly experience major regrets because of severe emotional trauma, complications of surgery, lack of postoperative psychological support, complications of reconstruction, phantom pain, and dissatisfaction with the procedure’s cosmetic outcome. Frost et al. (2000) performed a detailed research to investigate the overall social and psychological well-being and long-term satisfaction in women that have undergone prophylactic mastectomy. The researchers found a 74 per cent reduction in the emotional concern regarding the

Response paper to pride and prejudice by jane austen Essay

Response paper to pride and prejudice by jane austen - Essay Example r breaking up with Jane based on information brought to him by these same society friends because she does not come from their ‘set’ was surprising as was the idea that Jane would take him back anyway. However, I can understand that she would have done anything for him because she really did love him and the times were much different then. During the Victorian period, women were very limited in what they could do as a means of supporting themselves. Basically, if they wanted to have any chance at mingling with ‘polite’ society, they had to be aware of the more rigid rules of manners in high society and they had to try to find a husband early. That was pretty much everything they were born and educated to do. Outside of taking care of the house and the family, there weren’t many acceptable ways that girls could take care of themselves. They were usually considered the responsibility of a male relative, who was given the right to choose their husbands for them and had control over their money and activities. Girls who did not have male relatives to take care of them, like Charlotte Lucas, had to resort to the only field in which women could retain some degree of respectability, which was taking a position in someone’s home as a governess. The idea that even this was relatively horrible is expr essed when Charlotte would rather marry Mr. Collins, who she is not overly fond of, rather than become a governess somewhere. I really hated the idea that women were so limited in what they could do given all that they have accomplished in the past 100 years. Imagine what society would be like today if the whole population, rather than just half of it, was involved in it. Charlotte’s marriage to Mr. Collins is not seen to be the kind of happy love affair that eventually develops between Jane and Charles and Elizabeth and Darcy. Although Mr. Collins continues to call her by endearing names, he does so with such lack of feeling that one gets the

Mainstream Media In Malaysia

Mainstream Media In Malaysia The mainstream media in Malaysia has always been perceived as a key pillar of change for the most of the government policies. Nowadays, media play a role as helping to widespread information content, news coverage, ideas, opinions, and entertainment to gigantic audiences. According to the definition, media is defined as a channel that able to transfer messages to reach broad audiences in term of mass communication. Furthermore an array of media is available such as print media, broadcast media, Internet and etc. Print media is a medium by using printed materials to publish the information which is include newspaper, books, magazine, and broachers. In opposite, broadcast media is using electronic to send message that include devices of televisions, radio, CDs, and the other. Lastly, Internet also considered as one of the effective and latest technology that allows users to access to the web in anytime and anywhere you can. Internet contains emails, webpages, blogs, graphics, video download and social networking that could reach globally and nationally. As such government tends to use the variety of media to spread 1Malaysia concept around the globe and encourage Malaysia citizens to build a peaceful and harmony world. Advertisement is one of the effective ways in promoting, so government chooses to publish through the advertising that exert direct and indirect influence to increase the awareness of Malaysia citizen. Besides, they can also easily expose to the media content which is related to 1Malaysia concept in webpage, blogs, graphics and video as well. Government highlights the important of 1 Malaysia concept by repeating the advertising and audiences tend to remember the messages. The goal of 1 Malaysia concept is aim to achieve unity among different races, religions, beliefs and culture. At the same time, government needs media to approach to citizens and communicate towards the concept of 1 Malaysia. The Malaysia Government has putting much effort in promoting the concept by using mainstream media such as playing patriotic songs and Rukun Negara through television and radio. During Merdeka day, newspapers have also published wide range of topic about political and our multi racial country. Those publish materials not only helps to strengthen our national unity, the audiences also affected by the media after they saw the slogans in advertising. As a conclusion, government use mainstream media as a powerful tool to encourage the acceptance of the concept by the citizens of Malaysia. 1 Malaysia concept can be strengthens and generate desired outcome. Discussion Limited effect theory According to the Paradigm Shift, media were conceptualized as rarely have powerful and has direct influence towards the audiences. Media might have certain effect, but it is indirect influence as audiences always been affected by the people who surrounding them and opinion leaders. They can be influenced by variety factors such as individual interpretation, personal status, environment, education and etc. Besides, Lazarsfeld and Hovland also argued that effect of media towards audiences is limited and they disagree what implied in mass society theory. Lazarsfeld had developed a research study to measure the media influence and proof that media is powerless on shaping public opinion. And this theory is defined as Limited Effect Theory. It shows that there are minority of people were behaving vulnerable and tend to rely on mass media. Lazarsfeld and Hovland try to have better understanding towards media so they developed a media studies. They wish that media could be control well and use it in a proper way. But unfortunately, they realized that media were not as powerful as implied in mass society theory. Lazarsfeld believes in inductive approach which is start from empirical observation and develops a theory. From his research observation argued that if media is powerful, the propaganda is tend to reinforce and influences the voters candidate choice. And the results shows that majority of people are influences from others who surrounding them more than the media content. Thus, the gate keepers act as the opinion leaders that persuade and lead those opinion followers decision. They are the one who interpret the media information carefully and share their own view with the others. This also referred as two step flow. Based on this theory, opinion leaders own a characteristic such as active, aggressive, heavy media user and talkative which is usually tend to shape public opinion. In opposite, opinion followers are those who tend to follow. In conclusion, media is powerless in term on influence viewers opinion. For example, we are educated since we are young, so we are able to interpret the message from media and choose what to believe or not to believe. Media is lack powerful to convert viewers mind and beliefs as they got ability to analyze the media content, but not being vulnerable towards the manipulation of media and propaganda. Moreover, viewers also will base on their own different interpretation and influences to select whether to trust the media. Some of them might receive it differently, some of them might been influenced by their group membership as well. Opinion and views From my personal opinion, I am being neutral for the usage of mainstream media to promote 1 Malaysia concept. Media is able to effect audiences but with limited influences. The influence that occurs is indirectly which is based on individual differences. Government publishes about the important of unity among racial through television, radio, newspaper or Internet, but viewers can choose to receive the information or reject the messages. Promoting 1 Malaysia concept is not only relies on mainstream media to achieve the desired outcome; Malaysia government should have to consider individuals from different background, status, education and etc. Audiences have been educated since young, so they have held strong beliefs and certain mind set. Mass media is not so easily can change their attitude and behaviors in a short period of time. In fact, audiences are not vulnerable or just been force to receive the information from media. They can interpret and analyze, they will also get influenced through the interactive from the others as well. For example, they might receive the message from the 1 Malaysia advertising, but they are influenced by people who are surrounding them. Discussion 2 Diffusion of Innovation In another discussion, I will base on the diffusion of innovation theory which is explained how innovations are introduced and adopted by various communities. This theory was successfully developed by Everett M. Rogers and he extended the two step flow theory. There are 5 stages of info diffusion theory which is including innovators, early adopters, early majority, late majority and laggards. The adoption process usually begins from innovators. They are people who are knowledgeable; well- educated and tends to be aware about certain information from mass media. In this situation, when government use mainstream media to promote about 1 Malaysia concept. Innovators are more aware about the message and interprets based on their own knowledge. They expose to the media content, and understand about the functioning of 1 Malaysia concept. Moreover, they also gained education information towards the advertising such as Rukun Negara or patriotic songs; they will be behave more alert and remember the messages. Next, the innovation process will be adopted by a small group of people which is known as early adopters. They are the individual who are interested and try to seek for more details information after they saw the advertising. Most of the time, people tend to follow when the early adopters adapt to the innovation. In such, early adopters will take some necessary action after they exposed to the 1Malaysia advertising or media content. They will try to increase the unity among different races by giving commitment, organizing open house activity or be more aggressive to participate in patriotic events. Besides that, early majority is located in the third stage of process. At the same time they also referred as an opinion leaders. Early majority usually observe and refer to the innovators decision than only make the last decision. They own a characteristic such as active, aggressive, talkative, credibility and etc, so people tend to follow and believe the decision made by early majority when they share their views and opinions. Additionally, early majority always play a role as encourage and influence people in decision making. Based on the 1 Malaysia concept, early majority tend to persuade the opinion followers to believe and accept the the 1 Malaysia concept t that published by Malaysia government. They have the ability to motivate the others and successfully generate the desired objectivity of 1 Malaysia concept. For example, opinion leaders might encourage people to participate themselves in Malaysia patriotic events, and opinion followers will agree and follow his decision. During the fourth stage of innovation process, those opinion followers are tend to believe on the opinion leaders by giving full commitment. Opinion leaders will share their opinion, views, and past experiences to shape the public opinion. In this case, they are usually popular among the group, or an influential people. For example, opinion leaders convey the 1 Malaysia concept and sharing based on his own opinion. What he speck out is trustworthy and credibility, in such peoples are influenced by the opinion leaders and they will support and believe in his decision making. Lastly the end of the adoption process is the laggards. They also referred as the late majority. They can either be very traditional or more isolated in social system, as they not dare to take the risk and believe the information which is publish in mass media. Compare to the others, they usually take much longer time to adopt innovation and make changes. Based on the usage of mainstream media to promote the 1 Malaysia concepts, they might be the last group of people that try to move on and make changes. For example, they just try to expose and participate themselves in Malaysia patriotic events while the others already joined for many times. http://1malaysia.com.my/my/news_archive/government-to-adopt-moderation-approach-to-promote-global-peace-najib/ http://1malaysia.com.my/my/news_archive/najib-urges-media-to-help-promote-moderation/ http://transfomasimalaysia.blogspot.com/2011/03/1malaysia-concept-cannot-be.html http://www.thefreedictionary.com/print+media http://kifah-arifin.blogspot.com/2011/07/ways-to-strengthen-national-unity-among.html http://www.docstoc.com/docs/2216049/Limited-Effects-Theory-of-Mass-Communication http://www.stanford.edu/class/symbsys205/Diffusion%20of%20Innovations.htm http://www.des.ucdavis.edu/faculty/Richerson/BooksOnline/He19-95.pdf http://www.rogerclarke.com/SOS/InnDiff.html. Media manipulation often involves government or corporate propaganda and spin. Sometimes organizations and governments can feed fake news or politically or ideologically slanted stories to broadcasters which depict them as quality news items and journalism. In this way, the media can truly serve as a catalyst for development, he added. patriotic spiri to more strongly emphasise national unity and efficient governance. It is a principle that intends to guide and build a united and progressive nation. The concept is aimed at inculcating the spirit of togetherness and a sense of belonging among Malaysians, regardless of race, religion and creed.

Rucksack Rendezvous :: Traveling Travel World Vacation Essays

Rucksack Rendezvous Introduction "Deep in the jungle where the mighty tiger lie, Bill and his elephants were taken by surprise." -The Beatles For many people this is the image that is conjured up when one speaks of third world travel and many times it is this way because of lack of knowledge or lack of resources about the country in question. It is also possible that the person may not have had the chance to study the country and therefore does not clearly understand what goes on there. So many people think that a trip south of the boarder will bring them nothing but diarrhea and hassles. This image is simply not what you will find. Another scenario is that of the timid traveler who feels that traveling through such remote areas would prove treacherous or worse. Sometimes people are afraid that unrest may occur and they may be left with nowhere to turn. Once again this is a notion that is not completely realistic. The problem comes from the lack of information about these countries and an increased encouragement by national businesses to keep your travel funds in your own country. Many of the United States’ surrounding countries could benefit from the travel dollars that we as Americans tend to use exclusively in our country. However, the money is not going there. It seems to me that anyone spending there money for the experience of traveling through a third world country would be adequately compensated in life lessons. In this hemisphere alone there are so many travel destinations that it is enough to boggle the mind. It only takes some simple research before you will see that travel to third world countries is not only possible but affordable, safe, and practical. There are many people who have already found the pleasure that is experienced when visiting any one of the many natural wonders or urban settings of the world’s vast geographical locations. National Standards: Whether your traveling with a group or alone there is a valuable lesson to be learned in the area of using maps and other geographical tools to acquire and process information. Traveling also helps you to use mental maps in order to give spatial perspective to the world.
