Global warming - Essay Example Consequently, the carbon dioxide level in the atmosphere increases and thickens the ozone layer which in turn prevents the infrared radiation from escaping the earth’s atmosphere. This in turn results to warmer temperatures around the world. To make his presentation believable, Al Gore used statistical data. For instance, he mentioned about the top ten hottest years ever measured which occurred in the last fourteen years as of 2005 with the hottest of all in the said year. This shows the relentless increase in atmospheric temperature which is affecting the world. Moreover, Gore also compares photographs of glaciers in the past and in more recent times to impress in the minds of the listeners what he is trying to point out. He notes that the glaciers in Kilimanjaro, Glacier National Park, Columbia Glacier in Alaska, the Italian Alps and the Rhone Glacier in Switzerland are evidences of the results of global warming. The once majestic glaciers that attracted many scientists and tourists alike have all been decreased to nothing and more glaciers on the North Pole are at the brink of extinction as well. The effects of the aforementioned consequences of global warming are floods and droughts. This is due to increased precipitation and relocation of precipitation. For instance, in Africa alone, more droughts have worsened because of lack of rain while other places would have strong rains that are actually unusual. Moreover, it is not only sea water that evaporates and cause increased precipitation that in turn cause floods but the heat of the sun also sucks moisture from the soil which leads to droughts. In addition, the melting of the glaciers and Arctic ice caps are predicted to someday cause major floods in low areas and this should cause alarm today. This is explained by the result of studies that show that when the rays of the sun hit the ice caps, they are reflected back to the atmosphere just like in a mirror. On the other hand, when the rays of the sun hit the sea water; they are absorbed and therefore make the water warmer. As a result, the ice near the water melts and increases the volume of sea water. With the data presented by Gore which have obviously been carefully studied and are scientifically based, I strongly agree with all his arguments. The presentation does not just appeal to common sense but it also demands responsibility and accountability from listeners appealing to their moral senses. Indeed, global warming is not just a political issue but it also is an ethical issue which presents itself as the responsibility of every individual regardless of age, gender, political affiliations or beliefs. On another angle, on a more personal perspective, environmentalist Bill McKibben suggests that global warming is caused by people’s desires to have more. Economically, it is a good thing for individuals to want to succeed because it affects the nation’s economic stability. However, the want to have more things a ctually is increasing the carbon dioxide that is polluting the atmosphere. For instance, as more people are able to afford to buy more cars and appliances, more carbon dioxide is emitted from these machines. Moreover, with the fast-paced lifestyles of people wanting to earn more money, they are forced to eat processed foods which encourage more manufacturing processes that contribute to air pollution. Therefore, McKibben suggests people to live simpler

Macroeconomics Essay Example | Topics and Well Written Essays - 500 words - 7

Macroeconomics - Essay Example The demand side basically includes the overall increase in population and the usage of grain in vehicle operated with fuel. Yearly demand has almost doubled due to the increase in population. The increase in demand of the crops used to produce oil has reduced the amount of land which could instead be used to produce wheat. Whereas, on the supply side it is the weather related issues, high land prices and the limited availability of water that are leading to less production of wheat. Moreover, hoarding of wheat is also one of the major threats (issue) that government has to face every year. It is done by flour millers, private sector, government agencies, distributors, traders, retailers, thus almost all the intermediaries involved through procurement of wheat from farmers to it selling by retailers, everyone to their extent is involved in stockpiling. Considering the above mentioned demand and supply situation, government should try to balance the competing interests of the two sides. The supply side should aim at increasing wheat productivity and output and also supporting the farmer incomes whereas the demand side should aim at increasing household food security by ensuring abundant wheat availability at affordable prices. In order increase wheat supply, the bottom line or crux of any policy pertinent to wheat should revolve around one principal that is in case there is wheat shortage in the country; the deficit could be met by the international markets where the prices of importing wheat are comparatively

Computer networking and management - Essay Example The protocol constitutes two layers; one is the TLS Record Protocol and the other is TLS handshake protocol. Netgear (2005) further discusses that TLS Record Protocol is a layered protocol. There are different contents for messages at every layer; messages may contain fields for length or details about the message. Record Protocol performs a series of functions; takes the data/message which is desired to be transmitted to the other end, divides the data into smaller blocks, performs the compression function on the data if needed, applies a MAC and encrypts the message according to it and then finally transmits the result. The data which is received at the target server is decrypted, then verified if it has come from the expected host, decompressed and finally passed onto the target host. TLS Record has two main properties, which are discussed below: Connection between the two communicating entities is private. The technique that is used for data encryption is symmetric cryptography. The connection is secure because the key for this symmetric cryptography is unique for every connection, which is communicated between the two connecting applications by another protocol- TLS Handshake Protocol. If security of the connection can be compromised then it is possible to utilize the Record Protocol without encryption. Another characteristic about the protocol is that it provides a reliable connection; this is possible due to the provision of a message integrity check which works on a keyed MAC. The security of MAC is ensured by computing it with a secure hash functions. TLS Handshake Protocol gives a medium for the client and server to authenticate each other and to decide an encryption algorithm. Cryptographic keys are also negotiated among the two applications before any data is transferred or received by either. The steps for TLS handshake protocol are defined in the figure below; The negotiation process of the encryption algorithm is also secure therefore

Critiquing the Article Psycho-Social Factors Affecting Elders Research Paper

Critiquing the Article Psycho-Social Factors Affecting Elders - Research Paper Example Loiselle, McGrath, Polit, and Beck (2010) stated that a good title must reflect the key variables and the population being studied (p. 359). In this case, the article reflects psycho-social factors and maltreatment as variables under study and the elderly as the study population instead of Israeli elderly. Abstract An abstract should correctly summarize the problem, methods, design, results, conclusion, and implications of the study, must be convenient to the reader, and reflects the worthiness of the article (Taylor & Kermode, 2006, 86). Almost all of the contents of the abstract are correct and concise except for the method section. The abstract stated that a quantitative correlational method was used whereas the methodology section identified a quantitative correlational study which made the methods used conflicting. The author also thinks that the abstract of the article is too brief. Upon analysis of the article, the author noticed the following: the aim of the study is too gene ral and stated that the study will examine and analyze ‘major variables’ affecting maltreatment of elderly when the title specifically stated that psycho-social factors will be studied; theoretical frameworks should not be included in the aim and must be included in a separate subheading; the statistical methods were not stated in the abstract; and the conclusion and recommendations did not summarize or recommends anything as it only stated that it is first study to examine elder maltreatment in the long-term care population of Israel. Introduction Statement of the Problem. In my own words, the research problem should be stated as: â€Å"What are the psycho-social factors affecting Israeli elders’ maltreatment in long-term care facilities? What are the relationships of each psycho-social factor in Israeli elders’ maltreatment in long-term care facilities? What psycho-social factor has the major impact in Israeli elders’ maltreatment in long-term ca re facilities?† These are the research problems which came in my mind upon reading the article as it intends to examine and analyze psycho-social factors especially major factors that affect elders’ maltreatment in long-term care facilities. In addition, I have read in the discussion that relationships were identified for each psycho-social factor so the problem could be stated in a way that would illustrate the relationship between psycho-social factors and elders’ maltreatment. According to Loiselle, McGrath, Polit, and Beck (2010), the statement of the problem must be easy to identify, has clear concepts and study population, has significance for nursing, and matches with the paradigms and methods used (p. 359). The article only implied that elderly maltreatment is common in long-term care settings and include various behaviors but did not establish a problem statement; thus, it was not easy to identify. Concepts and population under study are clear and establ ished a cogent and persuasive argument for the new study as the full prevalence of elderly maltreatment in long-term care facilities is unknown. The problem has significance for nursing as it will address the factors on the side of the nurse that leads to maltreatment, leading to prevention. The article matched with paradigms such as the theoretical model for predicting causes of elder maltreatmen

How sex in advertising has negative effects on societies perception of Term Paper - 1

How sex in advertising has negative effects on societies perception of beauty - Term Paper Example This "How sex in advertising has negative effects on societies perception of beauty" essay outlines the impact of the usage of sex images in advertisement on our society and our standards of beauty. In most of the current advanced societies, children spend more times in front of televisions and computers rather than in play grounds. â€Å"Research has shown that young children—younger than 8 years—are cognitively and psychologically defenseless against advertising. They do not understand the notion of intent to sell and frequently accept advertising claims at face value†. Children during their early developmental stages may not possess the ability to segregate between good and evil. Moreover, children also possess intrinsic thirst for sexual activities even though it may not be visible or identifiable to others. When a sex provoking advertisement is displayed in front of the children, they are getting a new knowledge or a wrong message which they will keep in the ir mind forever. For example, bedroom scenes are common in the advertisements of condoms and beauty products. These advertisements often portray males as the symbol of strength or stamina and females as the symbol of beauty or figure. Children watching these advertisements may develop a feeling that only stronger men and beautiful women are capable of enjoying sexual life. In their 2002 thesis, â€Å"Effects of Sex in the Media,† scholars Richard J. Harris and Christina L. Scott address the effect of visual cultures whose morals are affected by this advertising. They say a worldview that progressively reflects the perception of the media may be refined by repeated contact to a regular set of messages. As an example, they say â€Å"watching numerous sitcoms and movies showing teenagers being sexually active may cultivate acceptance of such a position in the viewer and thus weaken family- taught values against pre-marital sex.† So, the viewing of sexual images in adverti sing also distorts the moral values of teenagers, maybe even to the point of rebellion against the values their family taught them (Robertson, p.2) â€Å"Sex is used in commercials to sell everything from beer to shampoo to cars. New research is showing that teenagers' exposure to sexual content in the media may be responsible for earlier onset of sexual intercourse or other

Otitis media, analyeses and evaluation the care delivered to a patient Essay

Otitis media, analyeses and evaluation the care delivered to a patient with otitis media - Essay Example Currently, decision-making processes have to be approved by the patient due to the consequences that may arise during treatments. As for otitis, the decisions have to be controlled by the doctor due to the various determinants. Additionally, the doctors use the factors to assist the patients on the decisions they can make on their treatment. Notably, previous research has simplified decision-making processes by having connection between symptoms and specific treatment methods that can be applied. Acute otitis media (AOM) – it is caused by blockages in the Eustachian tube due to poor drainage and ventilation of the inner and middle ear cavity (Rosenfeld 102). It does not take long, and its symptoms are short-term. The symptoms include increased temperature, nausea, ear ache and irritability among others. However, they may vary based on age body resistance. Chronic otitis media – it involves the entry of bacteria into the middle ear leading to infections (Bluestone and Jerome 103). The excreted fluid may cause conductive hearing loss and takes place after a period of more than three months. It is also referred to as the glue ear. Chronic suppurative otitis media – it is also referred to as the runny ear due to the presence of an opening in the eardrum. There is consistent discharge of fluids that may affect the inner bones (Bluestone and Jerome 5). This stage may lead to permanent hearing loss if treatment is not administered. Age is a factor affecting the choice of diagnostic approaches (Block and Christopher 56). Otitis media is commonly found in children below the ages of ten (Bluestone and Jerome 4). Moreover, the approach styles in children are different from those in adults. For example, an adult can explain in detailed the symptoms that he/she is undergoing; hence making it easy for the decision-making process. Children will have different diagnosis styles whereby the doctor will have to carry out tests and

An overview of Health Care Reform Research Paper

An overview of Health Care Reform - Research Paper Example The Medicaid expansion is expected to take place before 2014. In 2010, the Medicaid income eligibility level was 64% of the federal poverty level and currently only 11 states provide coverage for adults without dependent children. The expansion of Medicaid will avail services to individuals under 65 years of age who earn less than 133% of poverty, despite their family composition. The expansion makes it possible for children with the cover of children’s health insurance program to access the Medicaid services; the services provide more comprehensive children’s benefits package and lower cost sharing limits. The federal government will provide the finance of the Medicaid service. For enrollment of new members, the government will pay the full cost for the first three years. In 2017, the government will split 5% to be covered by the state. The state’s share of the cost of the expansion will then top out at 10% in 2019 and in future. The expansion of the Medicaid services will change how individual’s income will be calculated to create consistency; this will be in terms of tax credits available, for people who earn between 133 and 400 of federal poverty level. In 2014, states are expected to use modified adjusted gross income to determine the income of a family or an individual. This program covers over 7 million children of low income. The expansion will continue when the health reform provide the federal funding needed and, this will enable more children to be covered by the child insurance program. This should take place through the end of the federal year 2015 under the existing rules of that year. At the beginning of the year 2016, states will receive a 23% increase in coverage of the child health insurance program paid by the federal government. The program will need to be adjusted by the end of 2015 for the expansion to be experienced. By 2014
