Advantages and Disadvantages of the HPV Vaccine in Adolescent Girls: An Ethical Essay

Human papillomaviruses (HPV) are a group of more than 40 types of viruses that infect the genital areas, throats (recurrent respiratory papillomatosis), and mouths of males and females and is the number one most common sexually transmitted disease (Center for Disease Control and Prevention [CDC], 2009). It is spread by genital contact. It is most easily spread by vaginal and anal sex, but also through oral sex and even just genital-to-genital (skin-to-skin). In 90% of people that contract HPV, their own immune system clears it up within two years, most never even developing any symptoms from it (CDC, 2009). Out of the many types of HPV types, most end up causing warts on one of the above-mentioned areas, while a certain few are known to cause cervical cancer. Lockwood-Rayermann & McIntyre (2009) state that â€Å"[t]he most common oncogenic/high-risk virus types worldwide and in the United States are Types 16, 18, 31, 45, and 52; 11% of invasive cervical cancers in the United States are caused by Types 16 and 18 (55% by Type 16 and 22% by type 18). HPV Types 31, 45, and 52 comprise another 8% of all cases.† Cervical cancer is usually not detected until it is quite advanced, which is why women should get screened for cervical cancer regularly. There is also another precaution women can take. The Food and Drug Administration approved the very first vaccine to prevent cervical cancer by the types of HPV that cause it in June of 2006 (Thomas, 2008). This vaccine, being new, and therein little is known about its long term effects, has caused ethical debates about the use of it, particularly in adolescent girls. Thomas (2008) mentions that the CDC recommended, by a unanimous vote, that girls aged 11 to 12 years old receive this new HPV vaccine. This may seem  young, but in order for the vaccine to be effective, it must be administered before a person has been exposed to HPV, which happens during sexual encounters. Since few girls are sexually active at this age, most of whom haven’t gone through puberty yet, this is an ideal age to have them be vaccinated (Thomas, 2008). Thomas (2008) also goes on to say that this vaccine has been administered to 11,000 girls around the world with no serious side effects. Their ages ranged from 9 to 26 years old. This vaccine is given by a series of three shots over the course of six months and it’s important that they get all three to be effective, since little is known about the effectiveness of people who only receive one or two (2008). But is it ethical for a girl as young as nine years old to be receiving such an invasive procedure in order to avoid a sexually transmitted disease? After all, what nine year old is even thinking about sex and STDs? That is why this issue is one that is left for the parents to decide, and opinions are unsurprisingly mixed. One of the main arguments against vaccinating young girls with the HPV vaccine is cost. Thomas (2008) lists the total cost of this vaccine, for all three shots, as around three hundred dollars, relatively inexpensive considering the detrimental consequences of contracting one of the types that are known to cause cancer. There is another issue to take into consideration, though, when accounting for the price of this vaccination; the effects for protection are only estimated to be four or five years (2008). If a young girl were to be vaccinated at nine years old, and again at ages twelve, sixteen, and twenty, you are looking at close to one thousand dollars in total. How are parents with poor health insurance coverage or none at all supposed to protect their daughters for this virus that can cause cervical cancer? A parent can also anticipate losing a day’s pay to take their child to the doctor’s office or the clinic on three different occasions to receive all three shots. Because of the cost, and the limited duration of effectiveness, a lot of women decide not to get vaccinated and not to vaccinate their daughters, hoping that a better, longer lasting, and less expensive alternative will â€Å"arrive on the pharmaceutical market† at some point in the near future (2008). Another popular argument against HPV vaccination is that some parents view it as a green light for their daughters to behave promiscuously (Thomas, 2008). Much like condom distribution at high schools, there are those that view HPV vaccination as another way to promote, and cause a rise in irresponsible sexual behavior (2008). Thomas (2008) goes on to describe a conservative political group called the Traditional Values Coalition and how they have publicly denounced the HPV vaccine and claim that genital warts, cervical cancer, etc. are not a national health concern, and â€Å"that HPV can be prevented through abstinence and marital fidelity.† This group attributes â€Å"monetary gain† by pharmaceutical companies as a motive for the mandate for HPV vaccination. Like most every ethical or moral dilemma going on in this country, this issue rests in the parents’ religious and personal beliefs. Studies have shown that despite abstinence programs, teenagers still engage in sex, proving that something as insignificant as a vaccine is not going to encourage kids to have sex—they are having it anyway. Thomas (2008) cited a study that showed that 90% of teens are using condoms when they engage in sexual intercourse, but condoms alone cannot protect you from HPV, making the vaccine all that more important for young girls to receive. If a parents cannot set aside their religious and personal beliefs long enough to acknowledge that this vaccine has the potential to save their daughter’s life, then they may require a lot more than just education. Each year 6.2 million new cases of HPV come about and currently, 20 million people in this country are infected with HPV. The vaccine that is available has the potential to save 70% of the people it would otherwise infect from cervical cancer in young women (Thomas, 2008). â€Å"In 2008, an estimated 11,070 women in the United States will be diagnosed with cervical cancer, and 3, 870 women will die from the disease† (Lockwood-Raverrmann &McIntyre, 2009). Lockwood-Raverrmann & McIntyre (2009) go on to explain that the prevalence of HPV in peaks in women in their early twenties, and also go on to say that even younger women, i.e. teenagers, are more susceptible to the virus. They describe one possible explanation for this is because in younger women, it â€Å"could be the changing histology of the cervix following the commencement of puberty.† They go to say that â€Å"during this period of time, large populations of cells are undergoing maturation and are more  suscep tible to the development of an HPV infection† (2009). With all of this statistical data, it is confusing to think that some little girl’s parent’s are prepared to deprive her of a vaccine that could potentially save her life should the opportunity arise and she chooses to have sex. Again, said girl wouldn’t even have to have vaginal intercourse to contract Type 16 HPV, which would years later cause cervical cancer in which she could quite realistically die from. It is a frustrating and infuriating thought—that this girl could die because of her parent’s ignorance and/or their undyin

Cinema And Its Impact On Society Film Studies Essay

Cinema has the ability to unite amusement with communicating of thoughts. It has the possible entreaty for its audience. It surely leaves other media far behind in doing such an entreaty. As in literature, film has produced much which touches the innermost beds of the adult male. It mirrors the episodes in such a mode that leaves an impact on the coming coevalss. Cinema presents an image of the society in which it is born and the hopes, aspirations, defeat and contradictions present in any given societal order. In the present epoch, film is acquiring replaced by little screen productions. Televised seriess and programmes are replacing fad. They advertise and earn gross for industry. Thus movies telecast has become a beginning of farther income for the industry and trade. Man has inherent aptitudes, different ideas flow which leave an consequence on the heads. The individual laughs with the movies and cryings with them. Scenes of ‘Shaheed Bhagat Singh ‘ , a movie by Raj Kumar Santoshi and Manoj Goswami makes people national-minded and sentimentally involved in the movie show.

In the same manner, movie ‘Sholey ‘ created an imending consequence on so many. hypertext transfer protocol: //www.preservearticles.com/201106127879/essay-on-the-effect-of-cinema-on-our-society.html Example of Bengali Cinema and how it portrays: Bengali film is closely linked to Modernity and Realism. The most celebrated and celebrated movie shapers of the Bengali film along with the modernist ideas chose the genre of pragmatism to make to a new tallness. Ritwik Ghatak and Satyajit Ray are some of the greatest illustrations, who have played with the subject of pragmatism and modernness in their movies. Modernity is a huge subject and can be defined into many ways. But we will chiefly concentrate on the artistic, societal and political modernisation. Satyajit Ray ‘s movie ‘Pather Pancheli ‘ is one of the ultimate illustrations of movies portraying pragmatism along with several elements of modernness. It was an inspiration to Vittorio De Sicca ‘s Bicycle Thief, 1948 which was based on Italian neo-realism. Ray ‘s work was a shot of mastermind. It reflected the societal advancement and alteration in Bengal and besides had modernized thoughts and constructs. In his movie Pather Panchali, Ray has focused on go forthing the old thoughts behind, traveling on and working on new constructs. He put accent on the fact that, with the transition of clip the conventional ways of life, household thoughts and traditional life style have become out-of-date and needs to be altered consequently. During the flood tide, Apu and his household, leaves their place and subsequently departs from the small town. Their ascendant ‘s place was the exclusive ground why they were non go forthing that small town. They shifted to another topographic point for a better life and life manner. By relocating, they were able to sell off the old house which was of no usage to them, alternatively was the ground for their girl ‘s life. This movie is an development from traditional times to modern manner of life. Ray used many metaphors throughout his movie which were related to a demand for alteration and modernness. I think old aunt was a perfect illustration of metaphorical use. She was exhausted, old adult female who had nil to make than merely rolling around the house. She is often told by everyone to go forth which indicates that she is unwanted and worthless in the house. The household feared famine, survival and poorness. They were unhappy about the traditional manner of life and traditions. The same manner, they were annoyed by the presence of old aunt. Subsequently, we founds out that the old aunt meanders, after several unsuccessful efforts of seeking for a shelter topographic point, she dies. Death of old thoughts is the metaphorical significance of old aunt ‘s decease. Ray wishes for a alteration, something which is ne'er stoping. Through his illustrations, he focused on a demand for alteration so that we can interrupt off from the traditions which are keeping us back and is a signifier of barrier to our advancement. By agencies of aunt decease, he is able to demo how traditions have become outdated. Ray ‘s another great work Charulata ( 1964 ) , besides focuses on conveying a alteration. The narrative sets in an upper in-between category Bengali society. In this context, a only homemaker falls in love with her brother-in-law while they both were hiking each other to compose. He applied two different ideas of traditionality and modernness, place and desire and literature and political relations together. Ray ‘s movies have a humanistic attack. The deepness of his plant is far making. It has captured the human bosom and extracted the emotions from it. Apu throwing the necklace stolen by Durga, Amal go forthing place for the fright of being unfaithful, Durga stealing nutrient from her aunt are illustrations of Ray ‘s humanistic work. Ray is besides inspired by Neo-realism. From my point of position, it is because his narratives are mostly concentrating on the society. He can non do them fictional because so it would irrelevant to the society. His narratives are non meant to be movies, in fact a world which was an image of the society in which he has lived in. It was a complete imitation of Bengali society. The characters were portraiture of existent personalities. For illustration, Durga is Hindu fabulous character. When you look at her, you will non judge her as a good or evil character but will believe of her as a adult female who had existed in the yesteryear and had different properties which mirrored her personality. She was n't a fictional character. Correspondingly, Ritwik Ghatak ‘s movies introduced the modernistic subjects of isolation, disaffection and demand for place that evolves around the Bengali society. In his socially applicable movie Ajantrik, Ghatak brought together the construct of isolation and disaffection to the society. He demonstrates a adult male ‘s love for his auto ; auto is a exanimate object. That adult male had a disturbed societal life where he was non able to bond tighter with people around him. There are scenes like when Bimal is holding a conversation with his auto. He takes attention of his auto like he is a living comrade. At the same clip, did n't give importance to what the society says. This shows the importance of the auto, Jagaddal. Ghatak treat the auto as a life character and non as a prop. He besides showed the auto ‘s point of position. He wants to turn out his point that with the debut of modernisation ; nowadays people are more mercenary orientated. They value belongings more than dealingss. Similarly in Subarnarekha ( 1965 ) , Ghatak has focused more on the subject of place ( alongside the sub-themes such as dealingss and happiness.His work is besides approximately modernness, alteration and its effects and how divider affected Ghatak and the society. Subarnarekha is a after divider narrative of a household relocating to the bank of Subarnarekha River. Throughout the narrative, Sita hunt for felicity. He talks about the new place feeling and that she confesses her secrets, felicity and sufferings to a river. What I learned from Ghatak ‘s movies is he considers that society has transformed from being a community to a combined life of different characters. Individuality is present wholly over his work. Peoples have how people have gone from being lovers of nature and semisynthetic beauty ( like lakes and montains ) to autos and belongings. One may state that in the movies of both, Satyajit Ray and Ritwik Ghatak, you can happen many modernist necessities. Their work ranges from content to subjects like theanthropism, place and modernness ; besides their trade which is the usage of POV shootings, Brechtian elements, different manner of filming and pull stringsing infinite. Decision It is ever good and good groomed to see good topics on film. They have a really positive and durable consequence on the heads whereas inexpensive and moth-eaten films affect the stamp heads of audience really severely. There is general feeling that present twenty-four hours offenses are all due to effects of film. Besides unfastened and demonstrative topics throw tarnished messages. They spoil our civilization, and society. Cinema and TV severely affect the wellness of the childs. They neglect surveies and physical games to pass more clip on this amusement. School-going kids and society kids fail to do usage of good impacts and are influenced by the bad portion of the programmes on the air. The motivation is non to fling film or Television telecast so easy. The desirable act will be to selective and choosey for programmes. Good films should be seen by the pupils. The films of Television shows should be really much restricted and for a fix clip. The film exercises a great influence on the head of the people. It has a great educative value. It can accomplish glorious consequences in the field of enlargement of instruction. There are certain topics, such as scientific discipline and geographics, which can be more effec ­tively taught with the aid of talking pictures. Lessons on route sense, regulations of hygiene and civic sense can be taught to the pupils and the ‘ public every bit good in a really effectual mode with the aid of film images. Many successful experiments have been made in assorted states on the public-service corporation of movies as a agency of instruction. Feature movies have been produced for school and college pupils and pupils are being benefitted by them. Cinema movies have the power to act upon the thought of the people. They have changed the society and societal tendencies. They have introduced new manners in society. They may be described as pace-setters. They can make a direct impact on our societal life. Movies can travel a long manner towards eliciting national consciousness and besides in using the energies of the young person in societal reconstruc ­tion and nation-building by a adept adaptation of good moral, societal and educative subjects, and by debut of popular sentiments, movies can, to a great extent, formulate and guide public sentiment

The Sociological Reactions to the Return of Vietnam Veterans

The Sociological Reactions to the Return of Vietnam Veterans Upon their return from the Vietnam War, many veterans were shocked upon the reaction (or lack thereof) displayed by the citizens of the States who had remained on the home front. When finally landing back on American soil, many veterans expected to be greeted with celebration and maybe even a parade, acknowledging their service and dedication to the Vietnam cause.However, veterans were instead greeted by protestors who did not agree with the United States’ participation in the war (ironically, not all veterans wholly supported the cause itself, but instead went out of respect and devotion to their country). In an article written by Vietnam veteran Bill Hunt, it is clear to see that not only were strangers hostile towards veterans, but even friends and family treated the returning soldiers with annoyance, anger, or at the best, apathy.He states that it felt like family members had not even known he was at war; they re acted to his return much like one would react to someone returning from the grocery store: with just a casual hello, disregarding the danger and the high level of devotion that had been experienced. Hunt’s family barely acknowledged that he had ever even gone to war. The experiences of Vietnam vets were simply viewed as a part of every-day life.The war was not even taken seriously by many people, and veterans (specifically Hunt) were appalled by the flippant and insensitive (though innocent and thoughtless) comments made by others, family included. To the vets, it had been a hellish experience, and many experienced Post-Traumatic Stress Disorder, depression, and many became dependent on drugs and alcohol to get through the psychological after-effects of being involved in such stressful and torturous circumstances.However, appallingly, many were unable to get the help they needed. Medical aid was not made available to them right away, and a shocking percentage of Americans vie wed them as crazy and dangerous to society. Some even thought that the veterans deserved their psychological conditions. Suicide became increasingly common as many veterans experienced completely unfounded hatred and degradation. Part of this is due to the younger generation, which had begun the hippie movement.The ideas of â€Å"peace† and â€Å"love† were emphasized. Because of this, many returning veterans were greeted with shouts of â€Å"baby killer† and other completely untrue and offensive things. They were also given stereotypes of overarching drug use. Additionally, television was available to households for the first time. Because of this, there was no watering-down or censorship of the conditions of the Vietnam War. Many veterans were portrayed incorrectly and much confusion was experienced by the public due to mixed messages.Regardless of the cause, the fact remains that the Vietnam veterans are one of the most unjustly maligned groups of people in A merican history. The war was politically unpopular and many veterans were accused of a lack of dedication and â€Å"not fighting hard enough†. The disrespect that had been shown towards these veterans was and still is disgusting: regardless of whether or not one agrees with the cause, it is inexcusable that these veterans were not commended for their sacrifice. Comparison to The Return of a Private and Currently Returning Veterans The Return of a Private

Product Costing Essay Example | Topics and Well Written Essays - 1000 words

Product Costing - Essay Example But with the concept of management accounting system, John has decided to place in a better and sound managerial accounting system. The proposed solutions seem to be useful for John and Mary Farmers and other agricultural enterprises. Its basic aim is to gather better and vast information for managerial purposes and such information will be used in the long term as well. As, John and Mary Farmers are more keen in knowing the differences in the cost of production between farms and the profit difference between differing commodities produced over the years. To address this issue, the managerial accounting system will have its respected costs and profit centers. This method is more commonly known as â€Å"responsibility accounting†. Each service center is given its support cost centers. Those support cost centers are divided into activities and sites. These costs are further re-allocated to production cost centers. The marketing centers are concerned with the cost of marketing related with the products. Further on, profit centers are introduced, these profit centers account for both costs and revenue, the ke y performance measure of any profit center is therefore profit. This proposed costing system seems like a product costing system or an Activity Based Costing System. The benefit of having such systems is that each allocated center (either profit or cost) is responsible for its negative or positive variances. This system would prove beneficial for almost all agricultural businesses, with agricultural products having shorter life cycles and more complex production processes, this proposed system recognizes the complexity with its multiple cost drivers. Besides this, as the agricultural sector being a more competitive sector, this proposed system facilitates a better understanding of the driver of overhead costs. With all these positive feedbacks

American economics history exam Assignment Example | Topics and Well Written Essays - 750 words

American economics history exam - Assignment Example The action of Federal Reserve to raise interest rates hoping to slow the rapid rise in stock prices depressed interest-sensitive spending in institutions such as automobile purchases and construction. In addition, it resulted to the crash of the stock market, thus reducing the American aggregate demand substantially. The U.S. government has centralized great power and responsibility in one institution, which is the Federal Reserve in making significant decisions in relation to the economy. The significance of having a well-defined and secure property rights as it gives people the exclusive right of using their resources as they see fit (James 16). The fact that individuals are the dominion of their property, they take full account of the entire costs and benefits of employing those resources in a specific manner. The process in which they weigh costs and benefits produces efficient outcomes; therefore, translating into more prominent standards of living. However, in the last decades, during the history of modern economics, economists did not see the importance of property rights. Property rights impact the efficiency of resource allocation whereby the limit expropriation and facilitate market transactions. Moreover, they enhance investment incentives by limiting expropriation risk and reducing motive of diverting private resources in order to protect property. For an instant in U.S., the government has developed policies that protect the individuals’ property r ights in order for these individuals to trade in assets and improve collateralization of those assets. In the American history, between 1870’s to 1930’s, there were battles on business property because the judiciary saw that it was necessary to protect the general welfare (James 17). The problems with the Articles of Confederation were that the Articles were not precisely accurate or exact in an absolute sense. It is in the sense that when the Articles are viewed in a

Huge, bearded men bulging out of their leather vests and pants leered at me. I hid in the corner and tried not to make eye contact with anyone† (129). Although she is an intelligent woman, and many men who hang out in biker bars can carry on very interesting, very intelligent conversations, the physicality of the environment with the reciprocal stereotyping that evidently occurred (Bruckman saw the men as little more than thugs, the ‘thugs’ saw her as little more than meat) prevented any of these conversations from happening and precluded any possibility of future intellectual or cultural encounters. Issues of physical location between strangers are also overcome through online communities as discussed in the article â€Å"7 Things You Should Know About Blogs.† By removing questions of physicality, online communities can facilitate much greater communication among cultures and interest groups a s conversations are held according to true interest levels rather than being based upon or limited by a specific physical image or location. The ability of online communities to form regardless of physical location is emphasized in the article â€Å"7 Things You Should Know About Blogs.† In the traditional classroom, it is usually presumed that students are able to discuss various aspects of their lessons with each other.

On the Morning of Christs Nativity focuses on the Incarnation, Lycidas Essay

On the Morning of Christs Nativity focuses on the Incarnation, Lycidas on the Resurrection, but both treat of redemptive divine power. How does Miltons u - Essay Example Though the first poem, â€Å"On the morning of Christ’s Nativity,† deals primarily with the temporal aspect of Christ in the manger and the spectacle of such an event, Milton breaks through the constraints of time and accesses scenes of new life from diverse eras in order to feed the situation with its due amount of reverence. With the second poem, â€Å"Lycidas,† Milton does something similar, in that he treats the death of the mortal with such an eternal quality that it highlights the new and eternal life that is granted each human by the Christian doctrine to which he subscribed. In the poem that focuses on the birth of Christ, Milton effects a slight deviation of emphasis when he writes of the morning, rather than the night of Christ’s birth. The action has its desired effect, as morning is necessarily brings accompanied by the images of newness and life. The idea of Christ’s bringing redemption â€Å"from above† (1.4) dovetails with the image of the morning, as this new day or new life might be considered a gift from the rising sun, which issues its light from above. However, the comparison of the sun to Christ exists only in incipience here; later it becomes more obvious in the depiction of the sun recoiling in deference to the greater light of One who gives a greater life (VII.79-84). The idea of the Incarnation is present not just in the mention of Christ’s birth but in the treatment of the things surrounding it. Christ is named â€Å"that Light unsufferable† and is depicted as shedding the cover of his glorious environs; but being light, He penetrates and animates â€Å"a darksome house of mortal Clay† (II.14). This is a direct reference to the Incarnation, but it also calls forth the idea of the beginning of time and of all life, where God came down and animated not just the earth’s verdant cover, but the earth itself by blowing his breath into the clay and giving life to man. The image of death vanquished is also utilised as a method of

Accounting Ethics Can Make the Difference Reasons why Morals are Key Research Paper

Accounting Ethics Can Make the Difference Reasons why Morals are Key Components - Research Paper Example They don’t trust the financial statements, they don’t trust the audits, they don’t trust the bond rating agencies.† Indeed, contemporary profession of accountancy has been continuously wrestling with how to improve ethics in the profession. In the wake of prominent accounting scandals such as Enron, WorldCom, Tyco, and Arthur Andersen, the accounting profession in general and accounting ethics in the main has received both public’s and regulator’s glare. In 2002 the U.S. Congress responded to this dilemma with enactment of The Sarbanes-Oxley Act. However, when it seemed the regulatory field for adherence to accounting standards and ethics had been prepared, the world witnessed yet another crisis of accounting ethics triggered by unnoticed 50 billion Ponzi scheme invented and managed by Bernard Madoff for almost twenty years. Because the accounting profession is the gatekeeper of the financial affairs of the business community, it must strive t o cultivate and maintain ethical standards and principles that must not be compromised. Ethical sensitivity is paramount in conducting business honorably and fairly. Business communities around the globe hold accountants in high esteem and expect them to be beyond reproach, ethically. The primary existing paradigm related to accounting ethics is based on the premise that individuals make ethical choices because of individual integrity. This may be partially true; however, ethical or unethical accounting practices usually reflect the values, attitudes, beliefs, and behavior patterns of the organizational culture (True & Pelton, 2005). Early ethical and moral theorists have gone to great lengths to understand human behaviors and to define what behaviors constitute good morals. Some people believe that morality is contingent on environmental and situational circumstances. Dawson (2005) asserted that the character traits defining the ethical nature of the business are embedded in the social values of its culture. Dawson (2005) also believed that businesses with a strong rational and bureaucratic culture, such as financial institutions, have difficulty promoting individual ethical behavior beyond the rules in the absence of a compensating culture of social values such as trust and honesty. Businesses that thrive on the quality of human relationships internally and externally have more opportunity for building such a culture to promote ethical behavior. Those businesses with high employee turnover and a higher percentage of part-time/casual workers with low intrinsic valuation of work have difficulty sustaining a work ethic conductive to ethical behavior. Thus, ethical behavior is as much an organizational issue as it is a personal issue. Further, in some instances, ethical behavior is learned behavior that is based on formal educational instruction and personal experiences/modeling. According to position formed by Duska and Duska (2005), "accountants have a number of ethical responsibilities, to themselves, their families, and their profession as well as to the clients and company for which they work" (p. 30). Practically, most of accounting crises occurred in past primarily due to CEOs not adhering to the rules and regulations of the accounting practices as well as the U.S. Security Exchange Commission requirements. According to Healy-Burress (2010), "a professional code of conduct explicitly states the expectations of behavior and character for the members of the profession" (p.57). Therefore, a professional code of ethics that is followed by participants represents a defining feature of a profession, and the major document which formulates the ethical conduct of accounting

Russian Trade Profile Research Paper Example | Topics and Well Written Essays - 750 words - 2

Russian Trade Profile - Research Paper Example With regards to imports, the nation brings in food, pharmaceuticals, foot wear, textiles and ground transports (Lalayants p 41). The principal trading partners of Russia include China that controls 7% of total exports and 10% of total imports. Germany dominates over 7% of exports and about 8% of the total imports.In 2013, the Russia Federation's merchandise exports reduced by 1.1% despite the fact that the exports increased by 11.2%. This was a poor performance in relation to the Asia-Pacific's collective growth of 2.1% in merchandise exports, but higher than the region's 4.9% rise in service exports. The service imports grew by 18.2% while the merchandise imports rose by 2.2%. This trade surplus remained stable reaching $ 180 billion in 2013 as shown in figures 1 and 2. This resulted in the growth of GDP and GDP per capita ("Asia-Pacific Trade Briefs: Russian Federation").Russia also experiences the largest expansion in FDI inflows in 2013, that increased with 56.7% to $ 79 billion. This growth has been strong since 2011 surpassing the regional total of 6.6% for 2012 whereby the outflows were larger than the inflows. The outflows in 2013 grew by 94% reaching $ 95 billion as shown in figures 1 and 3 ("Asia-Pacific Trade Briefs: Russian Federation").Cyprus was Russia's largest investment accounting for 18% of the FDI inflows. It reflected her repatriation of the earlier investments caused by the Cyprus financial problems. This resulted in the creation of more employment.

Terrorism Response Strategy Essay Example | Topics and Well Written Essays - 1250 words

Terrorism Response Strategy - Essay Example When the preparatory actions are completed, the squad is ready for action. Since the toxins are unknown, the squad must wear the proper protection, i.e. PPE (personal protective equipment) lv.1 or A. This is the maximum level of protection. PPE can be used for site surveys, for emergency rescue, hazardous mitigation, and decontamination and for monitoring or supervising situations. There various levels of PPE depending on the situation. Level A PPE consists of vapor protective suit with pressure demand, full-face mask, inner chemical-resistant gloves and chemical resistant safety boots. This provides the best protection for eyes, skin and lungs from solid, liquid and gaseous material. Since there are bio-toxins involved, one has to add oxygen tanks to the suit, to avoid inhale outer air.Here now begins the scouting in the bomb site. The first objective of the scouting is not to find injured persons or forensic evidence, but to find a secondary exit point. This is very important if th ere is secondary explosion, or another disaster like a building falling, etc. Sampling is a very important step to determine what type of toxins if present. The step is to determine is the air is free from chemicals, by taking preliminary tests. The protocol is fast and easy to perform. A sample is first collected on two chemically treated swabs provided with the kit then each swab is immersed in a solution that produces a color change within five minutes only if the agent being tested for is present....

In the field, triage also sets priorities for evacuation to hospitals. Deceased are left where they fell, covered if necessary; note that in S.T.A.R.T. a person is not triaged "deceased" unless they are not breathing and an effort to reposition their airway has been unsuccessful. Immediate or Priority 1 (red) evacuation by MEDEVAC if available or ambulance as they need advanced medical care at once or within 1 hour. These people are in critical condition and would die without immediate assistance. Delayed or Priority 2 (yellow) can have their medical evacuation delayed until all immediate persons have been transported. These people are in stable condition but require medical assistance. Minor or Priority 3 (green) are not evacuated until all immediate and delayed persons have been evacuated. Continue to re-triage in

Creating a Safe and Healthy Work place Literature review - 1

Creating a Safe and Healthy Work place - Literature review Example The origins of a safe and healthy workplace have come in from the discussions which have centered on the premise of bringing out the best value for the sake of the most prized resources, i.e. the employees themselves. (Cantor, 2008). Ever since there has been debate on the pointer of the safe and healthy workplace domains, the employees have started to realize that they need to be offered the best possible avenues from where their growth and development could be ensured within the professional ranks. The safe and healthy workplace debates are being propagated because these center on the premise of bringing about a positive and the  incremental change – a change that happens for the wellness of the people at large, and in building solid links and relationships with the top management hierarchies. The safe and healthy workplace realms are always appreciated within the global organizations because these have been benchmarked with the passage of time. It is imperative to think o f these understandings in terms of the best practices as such, because this is the need of the hour (Cantor, 2008). What is significant here is to comprehend the fact that its origins get recharged whenever there are irregularities within the relevant systems, and when there is a dire need to get the act straight for the restoration of safe and healthy workplace domains. The safe and healthy workplace realms are staunchly built upon the rationale that the employees must receive the maximum benefits.

Wildlife Conservation in India Essay Example for Free

Wildlife Conservation in India Essay Nature is the major part that gave plenty of chances to flourish mankind. When it comes about doing justice, it’s all what nature do, but not us. We learnt from childhood to save others, to think for others first, and rest all the things. In fact, we are living all because of the nature. And when our turn came to save the nature, we are simply sitting back, relaxing as if nothing has happened. Therefore, the government of India started giving advertisements to save the nature or in easy language ‘Save Wildlife’. Many wildlife organizations are there who try to save and flourish the wildlife. Many natural projects and programmes have been undertaken by the Indian Government like Project Tiger, Nature Camps, and Jungle Lodges. These have been organized to promote the wildlife awareness among the people in every remote areas of India. All of these projects help preserving the natural heritage as well as encourages the eco-tourism. The wild beings are the gift of the nature that helps decorate the natural beauty by their exceptional ways of existence. Today, due to the rising deforestation and negligence, wildlife is receiving a threat that needs special attention from every human being. The green heritage of this world could only be saved by joining hands together. The population of tigers is day-by-day diminishing, and so to preserve and protect them government has taken some initiatives. It is today very important for every individual to know this major issue of wildlife. The education and awareness will at least help people to stop killing more animals or birds. The major example of efforts to save the endangered Rhinoceros is in the Kazirange Sanctuary in Assam. To protect wildlife like Elephants, Periyar in Kerala is also doing exceptionally well, where as, the Dachigam National Park is also joining its hand to save the Hangul or Kashmiri Stag. Gir National Park that is located in Gujarat is the only surviving home for the almost wiped out Asiatic Lions in India. Wildlife Conservation in India covers some 3.29 million square kilometers of area including the floral and faunal species, mammals, reptiles, insects, and birds. Today, the Wildlife Conservation in India has become the most renowned holiday destinations due to its diverseness. In India, you will get total 571 sanctuaries and reserve parks, sheltered by the Indian Government. Some of the significant Wildlife Sanctuaries that could be found in India are: * Bandhavgarh National Park in Madhya Pradesh * Corbett National Park in Uttar Pradesh * Kaziranga National Park in Assam * Sariska Wildlife Sanctuary in Rajasthan * Sunderbans National Park in West Bengal * Manas Tiger Reserve in Assam * Gir National Park Sanctuary in Gujarat * Kanha National Park in Madhya Pradesh * Periyar Wildlife Sanctuary in Kerala * Dachigam National Park in Jammu Kashmir Besides this, there are many other NGOs are also working on the wildlife conservation like Wildlife Society of Orissa, Rhino Foundation for Nature, Friends of Forests, North Eastern Society for Preservation of Nature and Wildlife, Nature’s Beckon, Nature Conservation Society Amravati, The Friends of the Doon and Bali Nature, and Wild Life Conservation Society. Wildlife aids in sustaining the balanced living systems of earth that as a result guarantees survival of life. In fact, by studying about the wildlife further, Scientists achieved lots of precious information about different life processes and discovered significant medical products. Tourists when throng to India to see the major attractions and make some memorable time, they make sure that the nation could offer them good sights of wildlife as well. So be the one to save our environment and wildlife and make India a thriving place for these living beings. Active conservation projects in India Tiger Conservation Programme Geographical location: Asia/Pacific Southern Asia India The project aims at conserving the tiger and the species that cohabit its habitat. Project activities primarily focus on conservation efforts within the protected areas and their adjoining forests. There is also a major effort to work with the local communities; primarily to mobilise support for the cause of tiger conservation, and at the same time bring economic benefits to the communities by means of innovative mutually benefitting activities. Objectives Provide support to protected areas to strengthen their anti-poaching activities. Play a facilitators role to develop, ratify and adopt strategies. Protect high priority landscapes and the biodiversity therein. Restore critical habitats. Solution The project relates to conservation action in the 3 priority tiger landscapes in India, i.e. the Sunderbans, Satpuda Maikal and the Terai Arc. In addition to working in the landscape, WWF will also provide support to protected areas to strengthen their anti-poaching capabilities. The proposed activities in the selected landscapes will involve working closely with the governmental and non-governmental agencies along with the local communities. WWF will play the role of catalytic role in facilitating the agencies to collaborate to develop, ratify and adopt strategies, protect important biodiversity areas, conserve landscapes of high priority and restore critical habitats. Asian Rhino and Elephant Action Strategy (AREAS) Geographical location: Asia/Pacific Asia General Asia/Pacific Southeast Asia Indonesia Asia/Pacific Southeast Asia Malaysia Asia/Pacific Southern Asia India Asia/Pacific Southern Asia Nepal Asia/Pacific Southern Asia Sri Lanka  © WWF Laos Summary WWF’s Asian Rhino and Elephant Action Strategy (AREAS) was set up to focus on the conservation of these iconic flagship species. The programme was developed on the back of priorities defined by WWF Asia/Pacific Regional Strategy. This project is concerned with the next phase of the AREAS programme and priorities will be further developed. Background With a few notable exceptions, populations of the 3 Asian rhino species (Greater One-horned rhinoceros (Rhinoceros unicornis), Javan rhinoceros (Rhinoceros sondaicus) and Sumatran rhinoceros (Dicerorhinus sumatrensis) and the Asian Elephant (Elephas maximus) have experienced major declines over the past few decades as a result of habitat loss, fragmentation, and poaching. Large mammals, like rhinos and elephants, are wide-ranging and require extensive areas to support viable populations. It is possible that rhino and elephant populations in several of Asias relatively small protected areas have reached carrying capacity, and the areas have inadequate ecological resources to support larger populations. The animals are unable to use the surrounding areas as habitat fragmentation of their natural habitat has led to the reserves becoming isolated. In many areas, the only chance to maintain or rebuild viable rhino and elephant populations is to include the larger landscape in conservation planning. Objectives 1. Expand existing reserves and creating new reserves where possible. 2. Link proximal protected areas by corridors. 3. Manage buffer zones so that wildlife conservation activities and other natural resources provide more benefits to the local communities than irreversible extraction of resources. 4. Encourage low-intensity land use throughout the conservation landscape that are compatible with wildlife use and dispersal, yet provide equivalent benefits. 5. Re-establish the traditions of the local people that once allowed a relatively benevolent coexistence with wildlife. 2. Conservation of Red Pandas 3. Geographical location: 4. Asia/Pacific Southern Asia India 5. 6.  © WWF-Canon / Martin HARVEY 7. Summary 8. Scientific information on the status of the red panda in Sikkim is very scant. While large areas are shown as red panda distribution areas, the reality is that only small pockets are available for the species. Authentic information on where exactly these animals are ranging and how exactly these places are connected and or what threatens these linkages is vital for creating strategies for effective conservation interventions. The Khangchendzonga landscape itself is a large area and the number of stakeholders is huge. Among them are government and non government agencies and influential individuals. These also include educational and research institutions that make key inputs into decision making. Bringing all of these together on a platform to make an alliance for conservation is expected to go a long way in achieving larger conservation goals. It is clear that the entire landscape including the Khangchendzonga Biosphere Reserve (Sikkim, India) is facing various threats. But there is no scientifically documented information that actually identifies the threats as well as shows levels of damage each one of them is causing or the potential of the damage that is waiting to happen. While this kind of dataset will appraise us of the level of interventions that are needed, it will also help in generating opinion among decision makers. 9. Background 10. Though the red panda (Ailurus fulgens) is the state animal of Sikkim and reported to be found in six protected areas (PAs) within the state (Choudhury 2001), its status in the wild is thought to be steadily declining (Lachhungpa 1997). Choudhury (2001) also reports that a 1,000 times increase in tourists in Sikkim between 1980 and 1995 and their subsequent requirement for firewood has accelerated habitat loss. In addition to this, he mentioned that construction of roads, over-grazing, etc. have also had their toll on the red panda habitats in Sikkim. The ecology of this species has been studied by Pradhan et al. (1999) in Singhalila National Park, West Bengal, an area that is adjacent to the state of Sikkim and has contiguous patches to this state’s largest PA, i.e. the Kanchenjunga National Park. The state of Sikkim is also likely to hold about 20% of the potential red panda habitat in India (Choudhury 2001). Therefore, in order to propose a conservation action plan for the species, the foremost activity to be carried out is to estimate the current status and distribution of the red panda in Sikkim. This activity will identify the PAs and other areas of red panda habitat that need immediate attention. 11. Objectives 12. 1. Understand the conservation status of the red panda in Sikkim. 2. Strategise for long-term conservation of the red panda. 3. Conduct feasibility for reintroductions of the red panda in order to create populations in identified sites. 13. Solution 14. It is known that the red panda inhabits sub-tropical and temperate forests (Choudhury 2001) wherein they are threatened from habitat loss and habitat fragmentation, competition from domestic livestock, reduction of habitat quality by removal of maternal den trees (Glatstone 1994). Hence, conservation needs for this species in Sikkim is to be determined and addressed. The weaknesses of the red panda habitats within and outside PAs are to be quantified and specific strengthening measures are to be implemented. All these activities will require to build-up a partnership with different government authorities like the Forest Department, the Indian army and NGOs like the Mountain Institute, Resources Himalaya and the International Centre for Integrated Mountain Development (ICIMOD). A broad-based awareness programme will also be initiated at the middle of the first year to make the people of the state aware about the conservation issues for this species. In due course of time, a tie up could be done with the Padmaja Naidu Himalayan Zoological Park, Darjeeling, which has successfully carried out an ex-situ conservation programme of red panda, by breeding this species in captivity and releasing them in the wild. Interestingly, one of the two individuals that were radio-collared and released in the Singhalila National Park, has mated in the wild and given birth to offspring. 15. Terai Arc Landscape securing corridors, curbing poaching and mitigating HWC 16. Geographical location: 17. Asia/Pacific Southern Asia India 18. 19.  © WWF-Canon / Helena Telkanranta 20. Summary 21. The Terai Arc Landscape contains spectacular forests, savannahs and grasslands, providing vital habitat for three endangered large mammals: tiger, elephant and rhinoceros. This project will focus on restoring wildlife corridors, poaching and mitigation of human/wildlife conflict (HWC). These activites will have an overall positive impact on wildlife and will be focused on the states of Uttarakhand and Uttar Pradesh. 22. Background 23. The Terai Arc Landscape (TAL) is spread over approximately 49,500 sq km and stretches from Nepal’s Bagmati river in the east to India’s Yamuna river in the west. TAL in India covers approximately 30,000 sq km across the states of Uttarakhand, Uttar Pradesh and Bihar. This area of India is about 50% forested. Vegetation in TAL-India consists of sal forests, sal mixed forests, riverine forests, mixed forests, grasslands and open scrubs. Some of the charismatic mega-fauna in TAL-India includes tiger (Panthera tigris), Asiatic elephant (Elephas maximus), great Indian one-horned rhinoceros (Rhinoceros unicornis), swamp deer (Cervus duvauceli duvauceli) and the Gangetic dolphin (Platanista gangetica). TAL is also drained by major rivers such as Sharda, Kosi, Ramganga, Gandak, Bagmati, Sonanadi, Rapti, and Saryu. TAL in India has 9 protected areas (PAs) which are Rajaji National Park, Corbett National Park and Tiger Reserve, Sonanadi Wildlife Sanctuary, Kishanpur Wildlife Sanctuary, Dudhwa National Park and Tiger Reserve, Katerniaghat Wildlife Sanctuary, Suhelwa Wildlife Sanctuary, Sohagibarwa Wildlife Sanctuary and Valmiki National Park and Tiger Reserve covering a total area of 4,500 sq km. TAL in India is among the most densely populated rural areas in the country as more than 20 million people reside here (2001 census). During the last two decades the population in TAL has increased by as much as 54.2%, which is 9% above the national average. Most of the poorer communities depend on the forest for their subsistence. Firewood, fodder and grass for thatching and rope making are the most significant resources extracted from the forests. Wild fruits, honey, medicinal plants, and leaves are some non-timber forest products (NTFPs) which are also extracted from the forests and these also contribute to the household economy of rural populations. Natural resource based occupations are predominant across TAL-India. Only 7% of the population uses purchased fuel such as liquefied petroleum gas (LPG), coal and kerosene in the entire TAL-India, the remainder using fuel wood collected from the forests. This landscape faces several threats like loss of wildlife and its habitat at an alarming rate. Habitat degradation and fragmentation due to biotic pressures and developmental activities are causing immense damage to the TAL. Livelihoods of millions of people are also at risk, as the natural resources in the TAL provide a means of income as well as vital ecological services, which are being lost as the landscape is further degraded. There are direct threats to wildlife in terms of poaching and conflicts with humans. There are tribes who have been hunting animals as a tradition and many of these still continue to do so. Meager amounts are offered to the villagers residing near forests by organized poachers to kill animals. On the other hand when the wild animals move out of the forest areas due to shrinking of natural habitat and come in conflict with the local people, most of the time it is the animal which loses out in the fight. Species which are already stripped of their habitats often face retaliatory killing. The main threats to wildlife conservation in the Indian part of TAL include corridor degradation; poaching, illegal extraction of natural resources and wildlife trade; high levels of human wildlife conflict; lack of participation from the local people; inappropriate policies and inadequate infrastructure support for implementing the wildlife conservation measures by the state departments. The root causes of some of these problems include limited capacity within the Forest Department (particularly staff outside the PA system, i.e. in the territorial forest divisions) to undertake effective wildlife conservation measures in the critical wildlife corridors and tackle the illegal wildlife trade. Another underlying cause of habitat degradation is weak community institutions and limited alternative livelihoods which lead to over-extraction of forest resources. 24. Objectives 25. Secure critical wildlife corridors within TAL-India; Curb wildlife poaching and illegal wildlife trade in TAL-India; Mitigate human-wildlife conflict in TAL-India; and Build strong community based institutions. 26. Solution 27. WWF-India proposes to work with the forest department and other government agencies securing critical corridors and curbing poaching and illegal wildlife trade. It will work with the forest department, local administration and with local communities and community based organizations to mitigate human-wildlife conflict. WWF will also work on the building of a community based institution for wildlife conservation. 28. Achievement 29. 1. Moved the Central and State Government to secure Gola wildlife corridor. 2. Working with different stakeholders for reducing wildlife trade. 3. Human wildlife conflict mitigated substantially around the Corbett Tiger Reserve.

Energy Policy For Libya Environmental Sciences Essay

Energy Policy For Libya Environmental Sciences Essay Libya is Africas largest oil producing and exporting country, located in the heart of North Africa, the country is home to 6 million inhabitants distributed over an area covering 1,750,000 Km2. Crude oil is an integral part of the Libyan economy and forms the basis on which the Libyan energy policy is formed, however, with increasing global drive towards more sustainable and renewable energy sources, admits issues of climate change, and global warming, there has been renewed and concerted efforts shown by nations around the world to adopt more sustainable energy sources, this has been highlighted in varied global convections and treaties amongst which are, the 1997 Kyoto Protocol, the 2009 Copenhagen summit to mention but a few. This paper attempts to highlight the place of a developing nation and major oil producer and exporter like Libya in renewed efforts to ensure lower dependence on fossil fuel sources, the countrys current energy policies and the state or extent of renewable en ergy resource in the country admits global CO2 reduction targets of 80% by 2050 to stem human contributions to climate change and global warming from fossil fuels. LIBYAN ENERGY BACKGROUND In Libya, the daily average of solar radiation on a horizontal plane is 7.1 kWh/m2/day within coastal regions, and 8.1 kWh/m2/day in the southern region, with average sun duration of more than 3500 hours per year (Saleh Ibrahim, 1993). The national electric grid consists of high, medium and low voltage networks of about 12,000 km, 12,500 km and 7,000 km power lines respectively with an installed capacity is 5600 MW and a peak Load of 3650 MW (Saleh Ibrahim et al., 1998). However, despite the remarkable energy network for a population of 6 million, energy is mainly concentrated in the major cities as many villages and remote areas are located far away from these networks. The small population and small consumption needs of these areas make their connection to the grid less economically viable. This has led to the use of small diesel generators in these areas contributing albeit minimally to the CO2 emissions. Furthermore the total dependence on fossil fuel sources for the generation o f electricity for the national grid belies the tenets of conventions and treaties on climate change, global warming and sustainable energy development. This however calls for the proper assessment of current energy policies in Libya and the place of renewable energy. Libyan renewable energy resource has the potential to provide clean and reliable energy sources which can be used in many applications in remote areas (electricity, water pumping, etc.) and even contribute to the national grid. Albeit the use of renewable energies has been introduced in a wide range of applications due to its convenience and economic attractiveness, application on a much larger scale in Libya has been hampered by the relative abundance of cheaper crude oil sources. GREEN HOUSE GAS EMISSIONS AND CLIMATE CHANGE Carbon emission has witnessed a meteoric rise since the turn of the Industrial age, Industrial processes have churned up 37 percent of amount of carbon in the atmosphere to date (Boden et al, 2009), Since the advent of industrialization, massive use of fossil fuels for energy generation have been recorded, there has been increase in the amount of gaseous waste produced in homes, and from transportation. These Gases collectively result in forming a layer in the earths atmosphere shielding radiated sunlight from the earths surface, depleting earths ozone layer and causing general warming of the earth. The effect of these gases is known as the green house effect, the process of gradual warming of the earth is Global warming and the gases are referred to as green house gases. The gradual increase in the earths overall temperatures has a telling effect on activities and life contained in it. Scientist predict, that rising green house gas levels would result in greater earth warming and invariably melting of the ice caps, increase in ocean mean water levels (20mm by 2020), increased flooding of coastal lands enhanced drought in arid lands (IPCC, 2007) etc, and these are part of the deleterious effect of climate change, which has led to a global outcry for the reduction in the emission of gases that give rise to this effect and the setting of CO2 reduction target of 80% by the year 2050. The earth is said to have warmed up by 0.740C over the last hundred years and about 0.40C of this occurred in the last decade (DEFRA, 2006). Agreements, declarations and treaties have been made in summits top on the list of which is the Copenhagen Summit of 2009 borne to develop and exploit means for carbon capture and storage, The Rio declaration of 1992 was to outline support for protection of the environment from the deleterious activities of man, while the Kyoto protocol of 1997, outlined the six major green house gases and set targets for governments to cut down on the production of these gases as waste. Human Drivers Greenhouse gases are released into the atmosphere by various mechanisms, chief amongst them is the burning of fossil fuels like coal, oil, and gas. Over the past fifty years, growth of the world economy has been hinged on worldwide energy use this has resulted in increase in global concentrations of carbon dioxide and other greenhouse gases in the air. The Kyoto Protocol highlighted anthropogenic emissions as a major cause and as an addendum listed six greenhouse gases. The KYOTO Protocol In 1997, the United Nations having evaluated the potential threat of global warming and the attendant causes (anthropogenic emission of greenhouse gases) proceeded to outlined the six major greenhouse gases and set targets (of 80% reduction in CO2 emissions by 2050) for national governments to cut down on the generation of these gases as waste or emit them as pollutants. The summit held in Kyoto Japan, entered into force in 2005. The Protocol which shared the ultimate objective of the Convention in Kyoto, Japan was to ensure that nations take steps to stabilize atmospheric concentrations of greenhouse gases ensuring that they do not exceed levels that will enhance dangerous interference with the already delicate climate system. The convention also attempted to build upon with a view to enhancing many of the commitments that were already in place under the Convention (UNFCCC 2007). Albeit the Kyoto Protocol was influenced by political factors, its ratification by most countries may be justified in light of the peculiar features of the global warming debacle, the existence of uncertainties, non-linearities and irreversibilities, possible catastrophes with small probabilities, asymmetric distribution of impacts, and the very long planning horizon (IPCC, 1996). The scientific uncertainties enshrouding the climate change and global warming still remain a rallying point for critics. The Kyoto Protocol tackles emissions of six greenhouse gases: carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); hydrofluorocarbons (HFCs); perfluorocarbons (PFCs); Sulphur hexafluoride (SF6). CURRENT LIBYAN ENERGY CLIME The Libyan economy has been heavily dependent on the hydrocarbon industry since the discovery of crude oil. In 2008, the hydrocarbon industry in Libya accounted for over 95% of the countrys export earnings, 85-90% of fiscal revenues and over 70% of Libyas gross domestic product (GDP) (IMF 2009). Libya holds the largest crude oil deposit in Africa amounting close to 44 billion barrels of oil reserves (OGJ 2010). EIA 2008 data indicate that 2008 total oil production in Libya was approximately 1.88 million barrels per day (bbl/d). Energy is the backbone of the economy availability of cheap energy compared to other Mediterranean countries has helped to the expansion of all sectors, like industry, commerce, construction and services. However, as much gas is found in the crude (associated gas), Libya engages in gas flaring activities (to get rid of associated gas) thus ensuring a steady and direct injection of greenhouse gases to the atmosphere. LIBYAN CONVENTIONAL ENERGY RESOURCES Current energy supply in Libya cannot be considered as sustainable sources of energy, with increasing cost of energy from attendant increase in exploration and refining cost, there is also the case of fuel sources being limited and environmental problems. Fossil fuel is limited or finite and Libya relies on energy from two limited conventional sources. Oil: With total discovered resources estimated to 44 billion bbl. Natural Gas: With total discovered resources estimated to 1300 billion m3. It is estimated that Libyas oil resources will not last more than 50 years with current rate of exploration and production, albeit natural gas is expected to last a little longer (Saleh 2006) It is projected that by the year 2050, prices of crude oil barrel may reach more than $200 while Libya would require about 70 million barrels of oil per year for electricity production requirement costing about 14 billion dollars annually. This would ultimately result in pressure on crude oil sources, its availability and increase in cost of generating electricity therefore underpinning the need for more sustainable forms of energy. By contrast, the abundance of potential sustainable energy in Libya decries the dependence on fossil fuels for example; the solar radiation in Libya is equivalent to a layer of 25 cm of crude oil per year on the land surface. Energy and emissions figures in libya Jacqueline 2000 reports that the amount of greenhouse gases emitted determines the magnitude and rate of future climate change, the sensitivity of climate to these gases and the degree to which the effects are modified by aerosol emissions. Libya, with 2002 estimations, had a 69.2 % energy consumption from oil and 30.8 % from natural gas, the emissions of CO2 attributed mainly to oil (71.7 %) and (28.3 %) natural gas (EIA, 2005), this means invariably that the energy sector which is the main source of greenhouse emissions in Libya depends mainly on fossil fuels (oil and natural gas). CO2 emission in Libya is put at 55.5 million tonnes per annum in 2009 following United Nations reports relating to 9.19 tonnes per capita and 31.5 tonnes per kilometre square (World Bank 2010). Libyan Energy consumption by Sector Current Libyan Energy consumption shows a total dependence on energy from fossil fuel sources. With domestic consumption of 273,000 bbl/d in 2008, shared within the sectors as described below. Residential 34% Industry 27% Commercial 27% Transport 12% Source: Oil and Gas Directory 2010. Figure 1: Current energy consumption in Libya by sector Table 1: Energy Production in Libya Type Production Consumption Export Natural Gas 12 b m3/y 3 b m3/y 9 b m3/y Oil 0.6 b bbl/y 0.1 b bbl/y 0.5 b bbl/y Electicity 20 T Wh/y Source: Saleh 2006 Environmental Impact Carbon Implication/ Future projections Libyan power stations utilize only fuel from fossil sources to generate electricity, and with the high demand of energy, from all the sectors which is estimated to more than double by 2050, there is going to be substantial increase in CO2 emissions by 2050, thus raising atmospheric carbon levels and contributing ever so gravely to the already deteriorating state of the climate. With the varied effect of global warming already being felt steps need to be taken to limit further emissions and manage present situation. Anthropic emissions of CO2 amounted to 26 billion tonnes in 2004. In a reference scenario extrapolating current trends, CO2 emissions are set to double by 2050, to more than 50 billion tonnes of CO2 a year. Continuing this trend would lead to an atmospheric concentration of CO2 exceeding 1,000ppm (parts per million) at the end of the 21st century, a concentration that is totally unacceptable in terms of its climate impact and its socio-economic consequences (IFP 2007). Global Warming Trends/ Future Trends In a bid to predict future climate change conditions, Scientists develop mathematically-based climate models. Adopting different assumptions on how various factors play to predict how atmospheric CO2 levels and temperatures will change in future. The variables in each model include: Population growth rate Economic development Energy use Efficiency of energy use Mix of energy technologies The graph below shows the results from three climate models used by the IPCC, with predictions starting in 1990 and ending in the year 2100. In all three, the global population rate rises during the first half of the century, and then declines. The A1B model assumes rapid economic growth and increased equity-the reduction of regional differences in per-person income. New and more efficient technologies are introduced, without relying heavily on a single energy source. The A1F1 model is the same as A1B, but assumes the continued use of fossil fuel-intensive technologies. In the B1 model, the world moves rapidly from a producer-consumer economy toward a service and information economy. There is a reduction in the use of raw materials, and an emphasis on clean and efficient technologies and improved equity. Other models have been developed, each based upon a different set of assumptions. Figure 2: Adapted from IPCC, Third Assessment Report on Climate Change, 2001. Global temperature increases predicted by three different IPCC climate models. Although differing in degree, these three climate prediction models show similar trends: The projected rate of global warming in the future is much larger than the rate of global warming during the 20th century. Predicted rates of global warming are greater than any seen in the past 10,000 years. (Exploring earth 2009) From the chart above it is clear where we have to take a stand. With the above stated premise and the statistical review, it is imperative to develop a strategy that first curtails present carbon emissions and subsequently reduces the overall generation from various sources described above. MITIGATING CLIMATE CHANGE VIA LIBYAN ENERGY POLICY INCORPORATING RENEWABLE ENERGY Strategies for reducing CO2 emissions by 80% by 2050 and Implementation Techniques Taking into cognisance current emission trends and sectors fingered in CO2 emissions, cutting down of emission cannot be over emphasized. A proactive approach to detailing of strategic plans of action for implementation must take into account past emission log; fully understand the current situation and project reduction measures that proffer solutions through a cost effective and practicable approach. To achieve these, the need to fully understand the scope of the problems at hand is imperative. To this end, I propose a utilitarian based all inclusive approach to reducing 80% emission by 2050. My approach is based on the incorporation of renewable energy in the Libyan energy policy. Libyan Renewable Energy Potential Libyan geographical location positions 88% of its area in the Sahara desert region of Africa, where there is a high propensity of solar energy which can be used to generate electricity via solar energy conversions, of both photovoltaic panels, and or thermally. According to the trans Mediterranean interconnection for concentrating solar power (MED-CSP)highlights Libyas renewable energy potention as depicted in the table below. Table 2: Renewable energy sources for Libya Type Potentiality Solar electricity 140,000 TWh/y Wind electricity 15 TWh/y Biomass 2 TWh/y Total 157,000 TWh/y Source: Saleh 2006 .This shows enough renewable resource potential to meet 3 times electricity demand in Libya by the year 2050 Renewable energy hold advantages over conventional fossil fuel sources for the provision of energy in that they portend convenience and are economically effective and viable in many areas of applications. Libyan renewable energy resource consists of photovoltaic conversion of solar energy, solar thermal applications, wind energy, and Biomass Solar Energy conversion of solar energy in Libya for electricity generations could be in two forms, the utilization of photovoltaics or solar thermal application. Thermal Conversions Solar heaters were introduced in Libya in 1983 with a pilot project that included 10 systems. The effectiveness of these systems has led to installation of about 2000 additional solar heaters. Figures show that water heating consumes about 12% of energy from national electricity production however, fundamental issues limit wider application of thermal converters for water heating in Libya, these issues include; Absence of decentralised national or personal electricity generation industry. Lack of information for the people. Low electric energy tariff. Solar Photovoltaics Operating on the simple principle of direct conversion of solar power into electricity, achieved by the agitation of electrons in P-N junctions by photons which thus creates an electric current which is tapped of by conducting wires. PV resource potential within Libya is enormous; current small scale applications highlight the use of PV in the following areas; PV in Microwave Communication Networks Amongst the 500 repeater station in Libya, 9 have been run by photovoltaic systems up until the end of 1997 producing a total peak power of 10.5 KWp. Of these, four still run after 26 years of work, with minimal maintenance as the batteries which they use are open type batteries and were replaced three times with an average lifetime of eight years. With the technical and economical success of PV systems, all communication networks previously powered by diesel generators were converted to PV systems thus effectively bringing the total number of PV run station to about 80. The total installed photovoltaic peak power by 2005 was around 420 KWp. (Saleh Ibrahim et al., 2003). PV in Cathodic protection Saleh Ibrahim et al., (2004), showed it cost $1.4 to supply one KWh of daily supply load of 15 KWh for a cathodic protection (CP) station located 5 Km from a 11 KV electric grid. Also another study showed that PV systems were more convenient and economical for the production of a daily CP load of 7.5 KWh from a distance of more than 1.2 Km from the 11 KV electric grid. This highlighted the importance and value of PV systems and hence their application. Further Future Applications PV systems in Rural Electrification In Libya rural areas face electrification problems because they are far away from the national grid and it wouldnt be economical to extend electric network to low demand areas, to this end the incorporation of PV systems would be invaluable. Currently, Libya plans to electrify rural areas consist of scattered houses, villages, and water pumping with PV systems, these Villages include; Mrair Gabis village, Swaihat village, Intlat village, Beer al-Merhan village, and Wadi Marsit village (Saleh Ibrahim et al., 2006) The installation of PV systems started in the middle of 2003. The total number of systems installed by General Electric company of Libya (GECOL) is 340 with a total capacity of 220 kWp, while the ones installed by the Center of Solar Energy Studies (CSES) and the Saharan Center are 150 with a total power of 125 KWp. The applications are: 380 systems for isolated houses, 30 systems for police stations, and 100 systems for street illumination. The total peak power is 345 KWp. PV for Water pumping The use of PV systems in Water pumping portends great advantages for rural communities as remote wells which are used to supply water for human and live stock that are located in rural places. Environment: It is worthy to note that the environmental impact of PV is less than that of any other renewable (Boyle 2004), however, concerns have been showed for toxic compounds used in the production of some PV e.g. Cadmium. Economics: From the word go, PV systems have continued to improve in cost effectiveness and if such a trend keeps up, it could become a force for contention with fossil fuels. Integration: With no medium for storing of electricity and the fluctuating nature of PV generation problems accrue over integration of PV electricity to the National grid. Although, the grid is designed to cope with massive fluctuations in demand, and similarly fluctuating supply like PV considered negative loads, analyst suggest that without large amounts of cheap electricity storage PV sources cannot make major contributions (Boyle 2004). Presently the conversion efficiency of PV cells is low (15%-30%) so this may hamper possibilities. Wind Energy Since 1940, wind energy has been utilized for water pumping in many oases. The potential of this renewable energy source has not been fully harnesses in Libya especially for powering rural communities and farms and use in irrigation. 2004 Libyan measurements of the wind speed statistics showed that there is a high potential for wind energy in Libya with the average wind speed at a 40 meter height is between 6- 7.5 m/s. The Libyan government has seen the potential in wind energy generation of electricity and have contracted the the project for use of wind energy for electricity production. This project includes the installation of a 25 MW wind farm as a pilot project. Also, a project to prepare two Atlas that provide fast access to reliable solar and wind data throughout Libya is also been contracted for. The Atlas will allow for accurate analysis of the available wind and solar resources anywhere in Libya, and will be therefore be invaluable to the planning of profitable wind farms a nd solar projects. In other to meet the target of an 80% reduction in CO2 emissions by 2050, it is imperative to tackle from source electricity generation which utilises fossil fuels by the setting up of an energy policy that seeks to ensure that energy from renewable energy sources contributes 10% to Libyas electricity demand by the year 2020. As stated above, photovoltaic has been used for small and medium sized remote applications with proven economic feasibility; however, several constraints and barriers, including costs exist. The experience of rural applications shows that there is a high potential of building large scale PV plants in the south of the Mediterranean. The potential for utilizing, home grid connected photovoltaic systems, large scale grid connected electricity generation using Wind farms, and solar thermal for electricity generation is great, with capacities of several thousands of MW. At the business end, Libya can expand its electricity generation capacities from its eneormous renewable source to meet the demands of Mediterranean countries, taking advantage of its proximity to the European energy market. This can be considered as a future plan. The potential for Solar energy resources to effectively replace oil and gas has to be harnessed. Renewable energy resources portend good opportunities for technology transfer and international cooperation. In the current Libyan energy clime, the decentralised nature of renewable energy technologies make them particularly well suited for rural energy development further enhancing use of the Clean Development Mechanism (CDM) adopted by Kyoto Protocol in renewable energy applications that wou ld reduce CO2 emissions. For Proper development of Libyan Renewable energy potential, the following have to be met: Promotion of private investment in transfer of renewable energy technology and services. Introduce renewable energy in formal education curriculum as well as Increase informal education on all energy aspects. Development of policies that support the introduction of renewables via local, national and international partnerships Courage the international investment to invest in the industry. International cooperation that seeks to aid the development and construction of large scale solar energy applications as a pilot project. Development and support, of technical, financial, and institutional, research mechanisms for sustainable development. Development of national energy policies and regulatory frameworks that would aid in the creation of the necessary economic, social and institutional conditions in the energy sector and improve access to reliable, affordable, economically viable socially acceptable and environmentally sound energy services for sustainable development. CONCLUSION Current Libyan energy policy depicts a system that lacks efficiency in the production and consumption of energy, challenge lies in the development of energy efficiency in the various sectors with several barriers including: lack of access to technology, capacity building, and institutional issues. In other to achieve energy efficiency in both energy consumption and production sides, it is imperative to incorporate renewable energy in all energy end-using sectors, the focus is on improving equipment efficiency of services, such as heating and air conditioning equipment, appliances, lighting and motors. On the supply and production side, energy management should focus on incorporation of renewable energy in energy generation, improved industrial processes, co generation and energy recovery systems. Energy efficiency can help reducing cost, preserving natural resources and protecting the environment.. Furthermore, as Libya is a non annex I country under the UNFCCC, and a signatory to the Kyoto protocol, Libya is currently eligible for the CDM. The main emitters of CO2 in 2003 are fuel combustion in the power generation sector. Libyas energy related CO2 emissions increased by more than 78% in one decade mostly due to increased energy supply and significant reduction could be achieved if improved energy utilization efficiency by the major energy sectors is encouraged. Conclusively, The Legislative Act Number 7 of 1982 concerning the protection of the environment which is Libyas biggest environmental protection act looks into a holistic plan to protect the environment, water, land, wildlife, plants, food etc from the deleterious activities of both man and nature. This piece of legislation which has a total of 11 sections and 75 articles was promulgated by the General Peoples Congress, Libyas highest executive authority. Below are the underlisted sections of this legislation: Section 1 General Provisions Section 2 Protection of the Atmosphere Section 3 Protection of Seas and Marine Resources Section 4 Protection of Water Resources Section 5 Protection of Foodstuffs Section 6 Environmental Health Section 7 Protection from Contagious Diseases Section 8 Soils and Plant Protection Section 9 Protection of Wildlife Section 10 Interim Provisions Section 11 Penalties The import of these legislation, and strict enforcements would help Libya in meeting the 2050 target of 80% reduction in CO2 emission.

Reflective Essay on Developing Care Skills

Reflective Essay on Developing Care Skills Part B Value 1 : Caring One of the values that I had learnt is caring. Caring meant concern about others. Caring for others starts from taking initiative to approach people with sincerity, care for them, to know them and care for their feelings. If everybody in this world does not care about each other, they will become selfish and do not have friends. Therefore, we must care for each other, so that everyone in every corner of the world is able to feel the warmth. As a future nurse, I must be more caring for my patients. I should not only be concerned about the diseases on the patients, but also concerned about psychological reactions of the patients. I believe that one warm word, a gentle attitude, a friendly expression can encourage patients to speak out the truth and this may facilitate the nurses to find out patients’ psychological problems. By this, I believe that I can understand my patients very well. During my Primary 3, I always asked my classmates why they did not want to make friend with me and they told me I was very selfish and arrogant. I knew that they always bad- mouthed about me. I knew the reason, but I did not bother it. I was so stubborn and did not want to change it. For me, I thought that it was not my fault. I blamed them for ignoring my feeling. In childhood, I was this kind of person, a very rebellious person. Time to time, I realized that I was quite lonely. At this time, I was very upset. Consequently, I told my dad about my problem. My dad was listening to my complaint patiently and he even did not scold me. He just smiled and told me I must change my attitude towards people around me. He wanted me to imagine the feeling if I have a friend with a bad attitude like me. He also told me that people will treat us for what we had done for them. He wanted me to be more caring about others’ feelings. I agreed to what he said. From that time, I just realized th at how bad I was. I did not want to continue to be like that anymore. I want to change! I want to be a caring person. I must care about people’s feelings. My dad and my classmates had changed me. After changing the attitude, I gained back my friends. The happiness was beyond description. Till today, I am still very grateful to them. Without them, I think I was still behaving like what I had done before. Value 2 : Responsible Another value that I had learnt is responsible. Responsible meant to complete the duty with a high spirit. Someone who is responsible will not make any excuses. In any case, we will always be faced with several factors beyond our control and irresponsible people tend to blame on these factors, take them as an excuse. To be a responsible people, we should make sure that we do not go the same way. As a future nurse, I must be responsible to my patient. By this, I must fully grasp my patient’s condition, care and treatment. Be a responsible nurse, I must closely observe patient’s symptoms and signs and identify changes in the disease as well as provide an effective intervention for medical diagnosis. I must not only alleviate the suffering of the patient, but also obtain the patients trust, give the patient a sense of security. It was happening during my secondary school time. It was still fresh in my memory. He is the one whom I admired the most. He is just a cleaner, but his spirit cannot get out of my mind. I truly admired his hardworking from my bottom heart. He had given me a deep impression until today I still cannot forget him. The first time I saw him was on the way going home from school. I still remembered it was raining cat and dog that day. People on the street all dressed in a raincoat and hurried home under the umbrella. At this time, I saw a huge rubbish heap next to my house. There was a man standing there. â€Å"Who is in there? It was raining heavily. It should not be a cleaner at there, right? † I mumble. With questions, I walked past. I cannot believe that I saw an uncle with a dusty face, wearing a tattered raincoat. He was very carefully cleaning up the rubbish. I was surprised by his action. I had never seen a cleaner still working in the heavy rain before. â€Å"Uncle, why ar e you still working in the heavy rain? You can do it tomorrow. Why are you working so hard?† I asked him. â€Å"No, I am just unhappy if I do not clean it by today. Then, there will be more bacteria growing and it was smelly as well as affecting our health.† he answered. This time, I was stunned. He was very responsible in his job. Since then, I have never seen him, but his spirit had inspired me to be a responsible person. Part C During my life journey, I had learnt the value of caring. I learnt I should care about my health. Health is the valuable asset. For having a healthy lifestyle, I must care about my eating habits. First of all, I must eat at least two servings of vegetables and one serving of fruits every day. Eating more vegetables and fruits can gain vitamins, strengthen the immune system and even reduce the chance of illness. On the other hand, breakfast is the most important meal, if we do not eat breakfast, we will lack of energy for the day and over time it will be harmful to the body. Moreover, a snack is a big killer. Snack contains much of salts, sugar and chemical components which may cause a lot of problems to our body. I also must exercise at least twice a week in order to achieve the effect of exercise. I also had learnt the value of responsible. Be a responsible person, I do not smoke. Smoking is harmful to our health and it may even causes lung cancer and other diseases. Not only that, I also must have a good mind state to evaluate myself properly and deal with the pressures of my life. I must be an optimistic, cheerful and open-minded attitude to life. On the other hand, I must also set a target to establish good relationships with people around me and also actively participate in social activities. This will help me to maintain my mental balance. Furthermore, I also practice meditation every day. Meditation can promote blood circulation and even relieve the stress. It is a good way to make myself to calm down. Part D During my clinical attachment in Tan Tock Seng Hospital, I met a patient named Mr. Khoo. He is a Chinese and his dialect is Cantonese. He now aged 60. I am also a Cantonese. So, sometimes I spoke Cantonese with him. He was admitted to the hospital because of foot ulcers which was caused by diabetes mellitus. Before he was admitted to the hospital, he stayed in Ren Ci Community Hospital. His left leg was amputated. During our conversation throughout one week time, he had told me his life experience. He had suffered from diabetes for 5 years. He had eaten a lot of hypoglycemic drugs. He told me that he did not take care of his health condition since young. He liked to drink Coke. He basically did not do any exercises. Due to long-term work at the grassroots level and slept late, so he accustomed not to get up early in the morning. Due to sitting in the office for a whole day or business meetings, he basically did not participate in any sports. He also told me he liked to eat meat. Duri ng the past, he had always eaten lamb stew as his supper before going to sleep and he usually did not take his breakfast the next morning. Due to the long-term excessive meat, plus he did not like to eat vegetables, fruits, beans and his daily staple food are meat, so his weight in the past 10 years has severely excessive. He suffered from diabetes because of the previous living conditions. From his life experience, I noticed that healthy lifestyle plays a vital role in our life. (1419 words)

Neanderthal Extinction Essay -- Anthropology Essays Paleontology Paper

Neanderthal Extinction    Neanderthals and modern humans coexisted for well over 100,000 years.   Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens.   Paleontologists and anthropologists have entertained several possibilities to the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of â€Å"survival of the fittest.†Ã‚   What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Scientists thought that interbreeding would be a logical assumption to the Neanderthal conundrum.   Unfortunately, any evidence of DNA from Neanderthals mixed with human DNA is difficult to come by because their fossils are usually tarnished upon finding.   That is until Svante Paabo, and his research team from the Max Planck Institute for Evolutionary Anthropology, came across the remains of twenty-four Neanderthals and forty early humans.*   All of these fossils were nearly 40,000 years old and were from Germany, Russia, and Croatia.   Nine of these fossils (four Neanderthal and five human) contained mitochondrial DNA (mtDNA), completely intact.   Mitochondrial DNA is tougher than the DNA found in cell nuclei; it is also found in the cytoplasm of a fertilized egg and is passed only through maternal lineage.   This makes it much easier for the team to study and makes testing more accurate.      Paabo’s team, from Leipzig, Germany, used a method of amino acid content as a way of measuring extractible DNA from the bones.   The amino acid method was a... ...ut there on what happened to the Neanderthals, such as competition or fighting.   Scientists also are aware of the fact that mtDNA is only carried from the mother.   This means that there may still be evidence of interbreeding out there that is carried from the male.   Our technology is not yet strong enough to rule out both sexes as a carrier of common genes.   Therefore the case of interbreeding still remains to be closed.   However Paabo and his team are confident that their research has proved that Neanderthals could not have died out solely because of interbreeding.   Scientists are still trying to conclude what exactly did the Neanderthals in; this discovery brings them one step closer, but not completely to the edge.   Source All references and resources are taken from the Public Library of Science, Biology March 2004 issue and from Science March 16, 2004

Prozac Causes More Deaths than Any Other Drug Essay -- Expository Caus

Prozac Causes More Deaths than Any Other Drug    Something is wrong with the focus on the "drug war" when 200,000 people die each year from prescription drugs, yet only 20,000 die from illegal drug use. Adverse reactions of prescription drugs are the third leading cause of death in America. In fact, people have a seven times greater chance of dying walking into their doctor's office than they do getting behind the wheel of their car! Every year approximately 200,000 souls die from prescription drug reactions with another 80,000 dying from medical malpractice (The International). Where is the FDA? Why do they continue to allow doctors to prescribe these drugs? How could they let it get to this point? What once was believed to be a panacia for depression has turned into Pandora's box (Tracy). Depression and suicide go hand in hand. In fact, 10 to 15 percent of depressed patients commit suicide (Lieber). This is the foundation of the defense argued by Eli Lilly, maker of Fluoxetine, commonly known as Prozac, and other companies manufacturing similar drugs. Although there are some 200 court cases alleging a link between suicide and Prozac this year, Eli Lilly continues to be cleared of all liability (Prozac and Suicide). One such case was brought up in Honolulu, Hawaii. In 1993, William Forsyth Sr., who was 63 and had been on Prozac for only two weeks, killed his wife, June, and himself. The plaintiffs argued that the side effects of Prozac, which included "nervousness, anxiety, insomnia, inner restlessness, manic behavior, self-mutilation and suicidal thoughts," were responsible for the murder-suicide. However, the Lilly spokesman said that those effects were "based on no scientific information at all." He also cited that the... ...data during trial." Cnn.com.
