Grand Canyon University Epidemiology and Communicable Diseases MRS.-IV Sandra White July 3, 2014 Epidemiology Hepatitis B We have come far in healthcare and everyday we get closer to solutions and can succeed in the understanding of disease processes unknown and foreign to us. We have been challenged many times by the illnesses that have taken so many lives but never in vain as when this unfortunate event has happened we have been able to get closer to a solution.The many diseases that have been a main factor in causing death are many however; we have come far in the vaccination process and treatments. In this paper we will focus on Hepatitis B. The virus that has been around for many years and was unknown to mankind until it became a global issues, causing scientists from all over the world to assess, evaluate and then research for a vaccination against this virus, in the 1965 by DRP Plumber however, it was licensed in the unites states in 1981 to be used as it showed a 90 or greate r % chance of treatment (â€Å"Hepatitis B foundation,† 2014).Writing about hepatitis B and talking about, people will understand that it is a virus which they should get vaccinated for or have their children vaccinated however, what truly is Hepatitis B and what does it do? Continuing on this important subject this writer will start off by explaining where this virus was discovered and where it could have manifested. We will also discuss the symptoms, treatment and environmental factors contributing to the disease. Including the nurses' role in the system. What can a health care worker contribute and teach the community?Hepatitis B (HUB) affects the liver of the infected person. It in turn causes scaring of he liver, liver diseases, death and liver cancer (CDC, 2014). The way a person can get infected in the first place varies. Many times one could get infected by blood ; open sores, sharing needles, unprotected intercourse and any other way of transferring blood from an exp osed person to an unexposed person. The infection is not such as HIVE, meaning you get infected once and then you raise immunity towards it and will not be exposed or get infected again.This also varies as some, will not get rid of the infection. If this occurs, where someone has been infected for more than six months hey will be considered a carrier and can easily without any sign and symptoms of infection, infect others. The symptoms vary from person to person however the main symptoms and side effects include and are not limited to, fever, Jaundice, abdominal pain, unexplained fatigue and unusual light colored stools, causing extreme gastrointestinal dysfunctions and pain (â€Å"Hepatitis B foundation,† 2014).A damaged liver caused by the HUB can be detrimental. The liver is an organ we can not survive without, it is as it would be an engine, cleaning the system; clearing the load of waste products, drugs, making clotting factors to stop excessive bleeding after cuts and i njuries. It also produces immune factors and will remove bacteria from the blood. Furthermore, it also releases bile to help digest food and absorb many nutrients needed (â€Å"Hepatitis B foundation,† 2014). HUB can cause liver cancer and if not treated immediately, it can be detrimental to the affected person.It is important to have a liver biopsy in this case and move forward with appropriate treatment such as any surgical removal of tumor or targeted liver chemotherapy. Treating and preventing this disease is mainly and most focused on certain age groups. It in this case has a demographic interest approach. Per the Hepatitis B Foundation, they report that the â€Å"risk of developing a chronic hepatitis infection is directly related to the age at which one becomes infected with the virus (â€Å"Hepatitis B foundation,† 2014).Per the Centers for disease control and prevention they report that the highest rated infected populations are infants with infected mothers, health care workers, intercourse between men, population who share needles between hem when using illicit drugs and any contact between infected and uninfected person. They continue to report that there is no acute treatment for an acute infection and that treatment is supportive, as many may also not have clear symptoms at first. Furthermore, per the world health organization, they report â€Å"more than 780 000 people die every year† form HUB in the world (WHO, 2014).The geographical distribution is such that the highest rate presents in the sub Sahara Africa and East Asia. We must understand that these are poor unprivileged areas in the world and cost likely and many times do not have enough access to education, vaccines or treatment. The world organization of health reports that most of these people in these areas are infected as children and 5-10 % of adults become chronically infected with HUB however, in general it is reported by WHO as well that 15-25% of adults who become chronically infected during childhood die from hepatitis B- related liver cancer or cirrhosis. WHO, 2014). Again, the vaccine has been available for everyone since 1982 shortly after it was discovered in 1965. It has shown and proven to decrease the infection by 95% (CDC, 2014). However, funding and availability of transport and financial support is lacking to spread the vaccination to these regions and could, unfortunately take many more lives before a solution can be reached and adding that â€Å"HUB and HCI infections account for the majority of cirrhosis and primary liver cancer throughout most of the world† (Peer,J. F. , Armstrong, G. L, 2006).Further discussing the HUB this writer will contrast it towards the epidemiology triangle, which was founded and created by researchers to better understand and solve health problems including viruses and infections. By researching around the epidemiology triangle for Hepatitis B we can understand that there is an agent, whi ch in this case would be the HUB (virus), which, then will infect the host (a human). Vertex number three is the environmental factor researches pertain to as â€Å"where†, the condition of the host, the outside factors causing the agent to reside on host and infect it.For hepatitis B we have confirmed that all the factors exist. The agent (HUB) will enter the host whom would be the human blood cells, in other words, HUB infection is caused by the virus which will penetrate in to the cell and release its gnome into it. As we will not go into the details of the viral life cycle but including that per the Journal by Lu X and Block Timothy, in their research, † Study of early steps of hepatitis B life cycle† they report that the virus will infect its host by three stages called; attachment, fusion and entry.The research is still ongoing on the specifics of the complete cycle of the HUB (Lu & Block, 2004). The environmental factor includes dried blood on surfaces, whi ch is infected, and if another person will have contact with it. Another environmental situation can be the needles found on streets seed by drug users whom can have been infected as well. When healthcare workers work with blood pathogens and areas where they could easily be exposed it is important for them to be vaccinated before hand as this environmental factor could have a deadly turn out.So what is the role of the community nurse in this case and in regards to hepatitis B? As nurses are to advocate for their community it is also a responsibility for some to step up in their role and collect data and analyze the case findings within the community. In this regard it is important and in many cases also a requirement for a ruse to obtain a baccalaureate degree in nursing and to then establish partnership and collaboration with public health professionals.It is important for the public health nurse to involve the community and their awareness on public safety, vaccination and preven tion of diseases. Some ways a public health nurse can participate is to help clinics control communicable diseases, educate and participate in environmental sanitation, health education including schools as well. To control and manage results, increase or decrease of disease within the community, a nurse could for example collect data by questionnaires.Another way would be to collaborate with laboratories by collecting data and assessing the results Furthermore, nurses should follow up with every patient who might have been infected or could be at risk for infection by doing home calls or call patients back to assess results and contribute further in education. There are many national agencies one can choose to seek further information from or refer a client too; one of them is the center for disease control and prevention. Another major agency is the world health organization, which also covers on an international level.Another online site that can be viewed is Hepatitis B foundati on with tremendous amount of information and the latest updates on research. For the serving and veterans the VA has many resources as well that can be visited. As the information has become vast and with new technology discovered, we are get a little closer to a wider solution and treatment including prevention. There are still many vast majorities of regions that are in need of proper education and preventive care such as vaccines however, with the appropriate funding and health care providers this goal can also be reached.

Oedipus/Antigone Response

Annie February 19, 2013 Oedipus / Antigone Response 1. What factors contributed to Antigone’s downfall, and does the end of the play satisfy the audience’s demands for justice? There are different factors that contribute to the downfall of Antigone. Firstly, the fact that two of her brothers have been fighting to death for the throne has had a negative impact on her life. She has lost both of her brothers at the same time. Secondly, Antigone believed that her decision was following divine justice. For example, she once said to Creon â€Å"Your order was outrageous. And lastly, she has been arrested and put into a cave for following her sense of justice has led to the downfall of Antigone. Despite the fact that Creon has taken back his words and fix what he did, everyone has died and hence, the audience’s demand for justice is not satisfied. 2. Referring to at least three tragic elements, determine whether Creon or Antigone is the more tragic hero(ine). According to â€Å"Once upon a Greek stage†, we can determine that Creon is definitely the more tragic hero than Antigone via some elements: hamartia, hubris and catharsis.First, hamartia is basically when Creon suffered greatly because of his actions. That caused the lost of his family and the support of his country. Next, the tragedy concept of hubris is largely demonstrated through Creon. For instance, as the king of Thebes, the people all looked to him for the answer. This made him believed that he was always right and everything had to go in the way he wanted to: â€Å"I am King of Thebes, Antigone. I have a duty as a monarch. Moreover, he also believed that his decision was right in the punishing of Antigone, despite that fact that she was engaged to Haemon, Creon’s son. â€Å"A broken law is a broken law, and lawbreakers must be punished. Antigone will be no exception. † In this case, his sense of pride was the tragic flaw that led him to his downfall. At the end , Creon finally realized that his pride has brought everything down, and also was the cause of his family’s death. Comparing to Antigone, in the end of the story, she still did not realize her faults and thought everything she did was following divine justice.About Creon, he was able to realize his mistakes at least, and this showed the tragedy of catharsis. The moment when he lost his wife and his son, it responded the sense of pity. Not only that, the sense of divine justice performed when he announced burying Polynices. Eventually, the conflict of the play developed him to be the more tragic hero than Antigone. 3. What universal truth is discussed within the play â€Å"Once upon a Greek stage†, and what implications result from this message? The play â€Å"once upon a Greek stage† contains a couple of universal truths.The fight between two blood brothers for the throne points out that family may not always support each other. Furthermore, Creon, uncle of Anti gone, has acted cruelly to Antigone and Polynices; once again justify the truth above. Both Polynices and Eteocles have done wrong but only Eteocles was buried. It points out the universal truth that life is not always fair. It implies that sometimes, you might not get what you deserved, and that luck plays a vital role in life. In conclusion, â€Å"Drama is a fine way of teaching a universal truth. † – Aristotle.

Analysing Economic Growth In Malaysia

Analysing Economic Growth In Malaysia Malaysia is a growing and relatively open economy. Three years ago, according to the World Bank (2007), the economy of Malaysia was the 29th largest economy in the world by purchasing power parity with gross domestic product estimated to be $357.9 billion for the particular year. By referring to the economy of the country, we can evoke that during the following long and severe period of recession, the Malaysian economy has started to grow through the interference of a relaxed monetary and fiscal policies and a high export demand in the electronics sector in particular. Despite the fact that the world economic slowdown was more accentuated than expected and the unprecedented events of September 11 in the US had affected all economies, Malaysia on the other hand was able to maneuver itself in a particular way from a major economic contraction and GDP growth for the year remained in positive territory. Nonethless, Rani (2007) stated that Malaysia has a coherent economic growth record i n GDP over the period 1970-2005. The author added that the economic growth record in GDP was in average 7 per cent at an annual rate. Such rate is characterized by the externalities which influence from time to time such as the oil crises of the 1970s, the downturn in the electronics industry in the mid 1980s, and definitely the Asian financial crisis of 1997. In addition, though given the openness of its economy, Malaysia was not spared from the negative effects of the United States economic slowdown. These effects were in the form of declining manufacturing production and negative export growth. In order to remedy the situation, the Malaysian government’s initiation of strong monetary and fiscal policies to stimulate economic growth through increasing activities related to domestic economy and decreasing the over-dependence on exports helped the nation to sustain a positive real GDP growth. Despite this, the MMoF (Malaysian Ministry of Finance) (2006) revealed that the stan dards of living of the majority of the population were transformed over the 30-year period with the level of GDP per capita in 2000 being about four times that of 1970. In other words, it can be quoted from the ministry that the boom in the economy went uninterrupted for almost a decade (1988-1996 with respective growths of 7 and 10 percent per annum). The ministry added that the main source of growth was the manufacturing sector whose share of GDP increased to 31.4 percent in 2005. One emmerging point highlighted Barlow (2001) is that Foreign Direct Investment (FDI) has been a key driver underlying the strong growth performance experienced by the Malaysian economy. Overview of the Malaysian Economic Growth and Developemnt Malasyia four almost forty years and through the World Bank’s countryà ¢Ã¢â€š ¬Ã‚ classification system was as a middleà ¢Ã¢â€š ¬Ã‚ income country. From then, the country had carried oenjoying a relative prosperity translated initially as a commodity ex porter of rubber, tin, then palm oil and petroleum which generated a total income of between 6 to 7 percent each year from 1970 until 2000. Athukorala, (2001) portrayed that the number of poor persons known as those consuming less than the purchasing power parity US$1 per day metric has fallen to fewer than a million, or 3.9 percent of the population of 26.2 million people (compared to about half of the population in 1970).

Critical Thinking 2 - Speech or Presentation Example All the sectors are related and affect each other. a) For each unit change of an independent variable, the change in the quantity of Chevys sold or demanded is equivalent to the coefficient of the variable. Therefore; a unitary change in the following independent variables will cause a corresponding change in quantity demanded by; The increase in the price of tickets resulted into increased profits in the short-run. However, in the long-run, profits declined owing to the fact that in the long-run, the customer is not willing to purchase the ticket at an increased price. a) These goods conform to the law of demand. This is because the law of demand states that an increase in the price of a commodity would lead to decrease in its demand as consumers would be less willing to purchase the commodity at a higher price, thus leading to a negative price elasticity of demand. On the other hand, an increase in consumer’s income would lead to an increase in demand of the commodity as consumers are able to consume more of the commodity, thus leading to a positive income elasticity of

MRKT discussion questions week04 Research Paper Example | Topics and Well Written Essays - 750 words

MRKT discussion questions week04 - Research Paper Example In low involvement product, differences in segmentation were not that evident and often ignored. The reason I can surmise why segmentation is more evident in high involvement product than low involvement product was that high involvement product takes so much resources and time from the consumer that segmentation becomes significant. For example, in the respondents whom I asked for their considerations before buying the car, the interviewees really made a careful thought before buying the car. Considerations like fuel consumption, maintenance, up front cost, performance, comparison with other cars, etc. were considered before buying the car if indeed it was a real value for their money. Here, cars that were positioned in the lower to middle segment in the market caught their attention. High end cars with exorbitant price tags were automatically struck off from their list. Therefore, the segmentation of the market in terms of price worked for my respondents even if they belong to uppe r middle class income bracket who could afford more expensive cars. To validate my initial assumption about segmentation, I asked a respondent why he is zeroing in on value cars and not the flashy cars which men typically like. He replied that he used to like but learned how to be frugal after the financial crisis because, as he said, â€Å"you never know, you might lose your job tomorrow.† He said that he has to be practical these days especially in high ticket items that will be purchased because of the uncertainty of the economy. Moreover, the money he saved from buying to value cars instead of the more expensive ones will go to his savings as a â€Å"buffer† during uncertainties. Comparing the car purchase with low involvement product, most of the respondents did not give much thought about the purchase and just put the product in their grocery baskets everytime they shop (the item I asked for low involvment product was shampoo). I asked them why and they replied t hat they are used to their brands already and they will only consider other brands if it is not available. I asked if price or other factors influence their buying behavior and they responded that only if it is very significant. But if it just within the price range of a regular shampoo, they do not mind slight difference. Perhaps this is more applicable to the segmentation of gender because the female respondents (two of them) were emphatic in having their particular brands due to reason that it â€Å"suits them† while the men were not that conscious about their shampoo and just pick up the same brand of shampoo out of familiarity but would not mind using another brand. 2. How would the marketing differ for the different segments you identify? High involvement products are high stake purchase for the consumers and they really take the time before making the purchase. As such, high involvement products are very conscious to position themselves according to the considerations of their target market. For example, in the car industry manufacturers that target the low to middle market astutely emphasize values in their products such as fuel efficiency, mileage, reliability and price. The reason for this positioning is that their market is price sensitive and they have to communicate and package themselves as the best value for their money. In the high end cars, they observably emphasize style, comfort and image to appeal to their market

Novel Response - Essay Example However, somehow despite the hostile environment and state, immediate sense of awe and wonder that is evoked is felt.  The members come to realize that they play a vital role individually and corporately to return the land. P. 72  "Shall we head up further for him, to the crags? Theres an Ogre or two and could introduce a Hag to it, up there." "Certainly not," said Caspian. "I should think not, indeed," said Truffle-hunter. "The same variety needs nothing on the minor." Besides the appropriate requirements. The imagination of the sense of unity and responsibility drives them to stand up for change in something real. P. 187 â€Å"However, the new bout went well. The shield may have certainly been used well by Peter and make use his feet skillfully. He almost played Tig with Miraz; shifting his ground to keep out of range, making the enemy work.† It is all about taking steps driven by the desire for change in order to attain the destroyed glory. (Lewis) The main conflict in the book is leadership tussle between a prince who is fighting for his crown and a false king who has taken the mantle. The prince was dethroned because he was young. Therefore, he was seen as not capable of leading. It narrows down to a battle of only two men who are to determine the fate of the entire world. This conflict is an external conflict that later involves all the members of the land. The conflict is resolved through battle and unity amongst the members of the land ending up in victory. The most favorable part is when Miraz is challenged by Peter to a High King duel. Peter become victorious as Miraz had tripped over a tussock and could never get up. Lord Glozelle whom he had earlier insulted in revenge killed him. The Narnians did the consequent battle with the help of Aslan. Finally Caspian is crowned as King of Narnia by Aslan, and this resulted to the door opening at the edge of the cliff. Telmarines who had gathered were give an option to choose to

Forensic science - fingerprint analysis Essay Example | Topics and Well Written Essays - 1000 words

Forensic science - fingerprint analysis - Essay Example Ninhydrin treatment involves dipping the items in a ninhydrin solution and allowing the prints to develop over 24 to 48 hours (Lennard, 2001). Physical developer is an aqueous solution, which contains a ferrous/ferric redox system along with silver nitrate and citric acid, and stabilised by a surfactant. Placing a document in the reagent, leads to the deposition of silver from the solution onto any latent fingermarks. The reaction is catalysed by water-insoluble components of the deposit (Lennard, 2001). Small particle reagent is a suspension of molybdenum disulfide in a detergent solution. Small particle reagent suspension can be applied with a spray and then rinsed with water to remove the excess powder (Lennard, 2001). Cyanoacrylate treatment is either with cyanoacrylate vapour or cyanoacrylate fuming, which results in the formation of a hard, white polymer on any latent print. The reaction is catalysed by moisture and ionic material present in the deposit. Cyanoacrylate fuming can be done with home-made chambers, expensive commercial units or portable fuming systems (Lennard, 2001). Basic Yellow 40 (BY40; Maxilon Flavine 10 GFF) is a non-toxic, highly fluorescent dye, which stains cyanoacrylate-developed latent prints. The stain has an excitation maximum at 440 nm with a luminescence emission peak at 490 nm. Basic Yellow 40 is very sensitive to ultraviolet light and can be used with a simple long-wavelength ultraviolet lamp (Security & Safety Supply.) When considering chemical treatments, the surface type is a major consideration. Latent fingermark deposits behave differently on different substrate types; therefore, some techniques are effective on some surfaces, but not on others (Lennard, 2001). For porous surfaces, the choice of chemical treatment will depend on whether the item was wet or not. If the item has been wet, the method
