Why The Us Needs The United Nations Essays - United Nations

Why The Us Needs The United Nations Why the US Needs the United Nations When sometimes one is given a question, thought is not required. Rather, history can answer with the loudest voice. The United States has proven time and time again to be the most powerful nation on earth, yet this nation does not abuse its power. It believes in righteousness and peace and only disputes when injustice is spawn. America does not turn away when another nation is in danger. It seeks to set wrongs right. With this position, America carries not a burden but a voluntary responsibility. It chooses to free people and maintain a world safe for democracy. Only when that goal is achieved may war only be experienced through history texts. Too many people of too many countries have suffered due to the tensions of conflicting governments that later catapult into hellish combat. There are only grave loses from war, nothing is gained, except torment and mortality. When will there be peace? The US is humane enough to answer this with a pledge to prevent war. It cannot be accomplished alone. Support is needed from all nations into one common alliance striving for peace. That is the United Nations. It was US President Roosevelt and British Prime Minister Churchill themselves who initiated this world organization. The United Nations not only performs peacekeeping activities and delivers humanitarian aid to distant countries, but it has a direct influence on all of our lives, every person everywhere in the world. The UN protects human rights, promotes protection of the environment, helps the advancement of women and children rights, battles epidemics, hunger, and poverty. Throughout the world the UN helps refugees, helps improve telecommunications, delivers food aid, protects consumers, make loans to developing countries and helps stabilize finanicial markets. The United States particularly feels responsible for all of these duties, whether the UN exists or not. Somewhere along the line, the US has become the police force of the world. If the world is kept secure, then international problems can be solved before the water ripples. But, aggressive situations cannot be pacified with polite words in a conference hall. Military force and financial funds are needed in the process of securing peace. Obviously, the US has its own nation to run, it wont abandon its country to save others. The US cant handle the financial burdens and world supervision to enforce such peace alone. A different perspective is to consider where the US would be if the UN did not exist. It certainly would not have as good overseas relations with troubled countries. Another world war could have easily occurred with the tension that existed between the United States and the Soviet Union. We the people wouldnt feel as secure about many aspects in our daily lives such as food, health, finances, environment, employment, and education. The United Nations touches so many facets of the government and the lives of the American people; its difficult to imagine our nation without it. Now the United States, along with 184 other nations, are united with the same goal to shape the international community. The United Nations is the lifeblood of world peace, we need it to correct inequity and create harmony for all humankind. Government Essays

How to Pronounce Italian American Surnames

How to Pronounce Italian American Surnames Everyone knows how to pronounce their last name, right? Since surnames are obviously a point of pride, its not hard to understand why families would insist on pronouncing them a certain way. But second- and third-generation Italian Americans who have little or no knowledge of Italian are often unaware of how to correctly pronounce their last names, resulting in anglicized versions that bear little aural resemblance to the original, intended form. Thats Not Italian In popular culture, on TV, in movies, and radio, Italian surnames are frequently mispronounced. Endings are truncated, extra syllables are added where none exist, and vowels are barely mouthed. Its no wonder, then, that many Italian Americans cannot pronounce their last names the way their forefathers did. If you cringe when hearing Italian words mispronounced, are interested in how your surname was meant to be pronounced in the original language, or want to recognize your own last name when spoken by a native Italian, there are a few simple rules to follow. When Paul Simon and Art Garfunkel sang, in the 1969 Grammy Awards Record of the Year song Mrs. Robinson, Where have you gone, Joe DiMaggio? they turned the Yankee Hall of Famers last name into four syllables. In fact, the Italian pronunciation should be dee-MAH-joh. In 2005, amidst the blanket media coverage of the Terri Schiavo case (brain-dead and in a coma, her husband went to court to have her taken off life support) the American media persisted in pronouncing her last name as SHY-vo, which to Italian speakers sounded very wrong. The correct pronunciation is skee-AH-voh. There are many other examples in which no attempt is made for even a close approximation of standard Italian pronunciation, which has lead to the spread of careless sounding out of Italian last names. Ironically, in Italy native Italian speakers struggle with the same dilemma of whether to pronounce surnames on the grounds of nationality (i.e., to italicize a last name) or on the basis of the origin of the surname. The Correct Way If many English speakers cannot seem to pronounce Italian last names correctly, how can you avoid common pronunciation mistakes in Italian? Remember that Italian is a phonetic language, which means words are usually pronounced as they are written. Determine how to break down your surname into syllables and learn how to pronounce Italian consonants and vowels. Ask a native Italian or someone fluent in the language how to pronounce your cognome italiano, or post a message on the forums such as: How to pronounce the surname Lucania correctly (hint: its not loo-KA-nia, or loo-CHA-nia, but loo-KAH-nee-ah). At some point, the linguistic clouds will part, and youll be able to pronounce your Italian last name as it was meant to be. Stumbling, Mumbling Pronunciation There are a few letter combinations in Italian that frequently trip up even the most assiduous speaker, and lead to the mangled pronunciation of last names. For example, Albert Ghiorso was the co-discoverer of a number of chemical elements. But pronouncing the surname Ghiorso shouldnt require a Ph.D. in chemistry. The scientists last name is not enunciated gee-OHR-so but rather ghee-OR-soh. Other potential tongue-twisters include double consonants, ch, gh, and the ever-tricky gli. Master these articulation challenges, and youll sound like a native when pronouncing memorable Italian last names such as: Pandimiglio, Schiaparelli, Squarcialupi, and Tagliaferro.

RELIGION - Essay Example As a result, he was able to perform miracles that proved that he was a supernatural being as the miracles work against the natural laws of science and human beliefs. Such include walking on water which violated the law of floatation, calming the storm which confirmed that he had power over nature, healing the sick which proved his abilities beyond those of man and multiplication of two fish and five loaves of bread which proved that matter can indeed be created. At the same time, being man, he felt pain, hunger and rejection from his close associates which makes it easy for Christians to identify closely with him knowing that he understands their afflictions very well since he personally went through them. The identity of Jesus as God makes Christians to be aware that the one whom they are following and believed in, has power over everything and they only need to strengthen their faith in him so as to experience him in their

Tropical rain forest Research Paper Example | Topics and Well Written Essays - 1250 words

Tropical rain forest - Research Paper Example Tropical rain forest Tropical rain forests are categorized into three: the monsoon, equatorial rain forests and the subtropical rainforests. They are characterized by very tall trees of different kinds and produce 40% of Earth’s oxygen. The trees form canopies which provide shelter to the plants and animals from the sun. Tropical rain forests host more than half of the estimated 10 million species of plants, animals and insects (Terashima, 49). The vegetation is ever green. The dominant species in the rain forests are plants, animals and insects. Location According to Newman (The Tropical rainforest), tropical rain forests are found on the earth’s surface between the tropic of cancer in the North and the tropical of cancer in the south around 23.5 degrees north and south of the equator. Areas around the equator receive a constant amount of sunlight and rainfall which favours the growth of rainforest. Tropical rain forests are mainly found in central and South America, South East Asia and is lands near it and in West Africa. The largest tropical rainforest across the globe is the Amazon rainforest. Climate According to Terashima (52), ecosystem is usually very wet with the total rainfall between 1500 and 2500 mm per year. Most of the rains stays on the rain forest, evaporates, cools to form clouds and fall again. The rainforest soils are infertile since the nutrients are washed away by the rains. There are usually no dry seasons and the day temperatures are around 30-35 Degree Celsius (Terborgh, The midday sun is always near the vertical and is overhead twice a year at the equinoxes. This means there is more direct sunlight hitting the ground and the sea and much water evaporates into the air (Newman, 2002). At night the temperatures range between 20-25 degrees Celsius. Little difference exists between the warmest and coolest months. Tropical rainforests have a high humidity and the type of climate is known as the equatorial climate. Tropical rainforest climate is found at latitudes within five degrees North and South of the equator. The high humidity is due to the warm sunlight, rainfall and the tree canopies which help retain the moisture. Major interactions Among the Organisms that live in the Tropical rain forests Competition According to University of Michigan (The Tropical Rainforest) there is a wide diversity of animals in the tropical rain forests. The tropical birds such as Costa Rica, parrots, macaws and hornbills eat fruits, nuts insects, seeds and nectar. Monkeys such as gorilla and the Lar gibbon feed on leaves, fruits, leaves and bark while the orang-utan and spider monkey feed on leaves fruits, nuts, seeds and insects. Also in Whitemore (195), spiders which live on the canopies eat fruits and leaves hence competing with the birds and some mammal for food in the ecosystem. Both the birds, monkeys and spiders compete for the same food in the ecosystem. Predation The bats also prey on frogs which also prey on insects. Jaguar feeds on r odents and frogs the bats and the jaguar are the predators whereas the frogs and other rodents are the prey. Snakes which are also predators feed on other rodents (Terborgh, 121). Predators use poison, camouflage and strength to kill their prey. Man is another predator whose prey is edible animals and plants. Men use the animals and plant

Chapter 5 - Coursework Example y police officers can greatly improve their effectiveness within a specific community by improving their roles as trusted and responsible police officers who are willing to help people. This would encourage citizens to develop trust on the police officers and they would report crimes to them without any fear. Other strategies include citizen contact patrol which is focused on developing sound relations between the citizens and the officers by their door-to-door visits. Also, improving the image of police officers in the minds of the citizens, focusing more on community meetings, disseminating crime control newsletters, establishing storefronts and substations to make people feel protected, organizing neighborhood watch programs to monitor and control the suspicious activities, specialized patrols and hosting community meetings where the citizens can freely discuss their problems and fears to police officers. Citizen contact patrol is a way to develop interaction between the citizens and the police officers which includes door-to-door police visits. During their visits, police officers provide general information on all the possibilities to control crime within the community, give out tips to protect oneself from any possible danger and collects information on who is carrying a gun in the house. In my opinion, citizen contact patrol is an effective way to develop greater interaction with the citizens and at the same time, it helps in lowering the rate of victimization. It improves the image of a police officer, enables them to collect sensitive information from the citizens and last but not the least, it provides awareness to the citizens on how to protect themselves in case of emergency and to report police. Police in schools is another technique to control crimes and to protect the minors who are at greater risk of danger. These police officers are often known as school resource officers (John L. Worrall). The presence of police officers at schools would

Whats Eating Gilbert Grape Film Review Film Studies Essay

Whats Eating Gilbert Grape Film Review Film Studies Essay Societys ideological constructs and attitudes towards minority groups are created and reinforced through media imagery. Although negative associations that maintain inequities with regard to race, gender and homophobia (Conner Bejoian, 2006) have been somewhat relieved, disability is still immersed in harmful connotations that restrict and inhibit the life of people with disabilities in our society. Disability has appeared frequently in recent films (Byrd Elliot, 1988), a reflection of societys interest in the subject. These films often misrepresent disability using stereotypes. These stereotypes reinforce negative and incorrect social perceptions of, and attitudes towards, disabled people (Safran, 2000). By studying these films we can begin to reshape the wrong and negative accepted ideas of disability in society. Film analysis can show students how the medium manipulates images which continue stereotypes and cause stigma (Livingstone, 2004). Film can be used to confront students with their prejudices (Chellew, 2000, p.26), challenging them to accept new ways of thinking realising that disability is a result of the social attitudes and expectations placed on certain people by society (Ellis, 2003; Meekosha, 2003). Whats Eating Gilbert Grape is a film by director Lasse Hallstrà ¶m about a young man looking after his developmentally disabled brother and his dysfunctional family in a small American town. This paper will critically examine this movie using Richard Dyers four senses of representation, as cited in Harnett (2000), as a framework. With a focus on the disabled character Arnie, the analysis will identify and discuss the ways the film reinforces limiting stereotypes about disability. Finally, the implications of the analysis for use in an educational setting to raise awareness of the representations identified will be discussed. Re-presentation, as the first sense of representation, refers to how television or other visual media re-present our society back to us (Dyer cited in Harnett, 2000). Through the use of artistic expression and technical elements neither true reality nor an entirely false account is portrayed. Dyer states that reality is always more extensive and complicated than any system of representation can comprehend (Titchkosky, 2003, p. 134). In societys media, the world is generally simplified or typically presented in a way that is most beneficial for the medium. The presence of disability in a film is often used for storytelling (Raynor and Hayward, 2009). In Whats Eating Gilbert Grape, Arnies disability is constructed as an emphasis of the film. The film relies greatly on the dramatic power of the disability alone (p. 23) to move the narrative forward. The selection and focus of particular aspects of Arnies life and his disability are used to explain his actions and evoke reactions from the audience. For example, when his fear of jumping in the water is overcome, it creates a feel-good factor. Also, the focus on his inability to cope, generates a sense of pity from the audience such as in one particular scene when Gilbert leaves Arnie to get out of the bath by himself, only to discover him still in the bath, cold and shivering, in the morning. Dyers second sense of representation refers to the application of common stereotypes that have been recognised for characters with disabilities in film. These stereotypes create one dimensional characters with limited emotions, where the disability comes first and the person second, justifying differential treatment and segregation (Black, 2004). Some of the negative representations identified by Safran (2000) as stereotypical for disabled characters will now be applied to the character of Arnie. As mentioned above, the portrayal of Arnies character demands a feeling of pity from the audience. This stereotype communicates disability as a problem of social, physical and emotional confinement (Hayes Black, 2003, p.114). In Whats Eating Gilbert Grape, Arnie has no friends and is restricted to the confines of the porch of his family home. Whenever he tries to escape (usually to the water tower), he is ultimately returned back to this position of subordination under the care of others, which is typical of this stereotype (Hayes Black, 2003). A most common stereotype depicted of disabled characters is that of a super-man (Safran, 2000) or supercrip (Harnett, 2000), where a disabled character overcomes massive odds to beat or succeed in defeating their disability to become normal. The character is often seen as a hero to have made such progress. Although Arnie does not reflect a hero status, his character is beating his disability by the very fact that he is still alive. In the opening scenes of the movie, Gilberts narration lets the audience know that doctors said wed be lucky if Arnie lived to be ten, well ten came and went (Matalon, Ohlsson, Teper Hallstrà ¶m, 1993), implying Arnies triumph over tragedy. He defies death that would be otherwise be brought about by his disability. Although not a thematic stereotype reinforced throughout this whole film, it is typical of a disabled character to be represented as a victim or object of violence (Safran, 2000). At the climax of the film, Gilberts overwhelming frustration and anger of his life situation overflows into a violent episode directed at Arnie. On occasions throughout the film, Arnie is portrayed as an innocent a victim or object of violence from his younger sister and, in this rare case mentioned above, from his brother Gilbert. Another stereotype of disability presented, albeit only slightly, however still present, is that of being laughable (Safran, 2000) or the disability creating an atmosphere of curiosity that is aroused by differentness. This stereotype is usually more prevalent in comics, horror movies or science fiction films and related to physical impairments, which often portray disabled characters as freaks and exotic creatures (Smith, 1999). However, in Whats Eating Gilbert Grape, its Arnies unusual actions within the community that attracts attention. When he is perched high up on the water tower ladder, it becomes a fascination to many onlookers, who crowd below the tower to observe the spectacle with curiosity, as Smith (1999) puts it, his abnormal behaviour is exploited as it would a carnival sideshow (p. 42). The most prevalent stereotype of a disabled character represented in Whats Eating Gilbert Grape is the stereotype of a burden. This representation is the major narrative driving force. In the opening scenes, referring to Arnie, Gilbert quotes some days you want him live, some days you dont (Matalon, Ohlsson, Teper Hallstrà ¶m, 1993), reflecting the huge burden that is placed on the Grape family, particularly Gilbert, to care for his disabled brother. The burden of Arnie is also extended to the community, where the local police have to continuously retrieve Arnie from the ladder of the towns water tower. Dyers third sense of representation of refers to the representation of who is speaking for whom (Harnett, 2000). Whats Eating Gilbert Grape is written by an able-bodied writer, directed by an able-bodied director and has a disabled character acted by, Leonardo Di Caprio, an able-bodied actor. On a study into disabled actors, Raynor and Hayward (2007) discuss how disabled actors work is restricted to disabled character roles and suggest their struggle to find work is partly due to able-bodies actors being cast in those roles. Marks (1999) suggests the reason for not employing disabled people is that it is reassuring for the viewer to know that its only pretend' (p. 160). In Whats Eating Gilbert Grape the audience knows Leonardo Di Caprio is not really disabled, he presents as non-threatening and comforting, perhaps allowing the audience to relieve fears or ignore the reality of disability. Dyers fourth sense of representation questions how the represented image is interpreted by the audience (Harnett, 2000). It refers to how the intended meaning by those who produce the film can be lost or skewed when observed from a different point of view. When Peter Hedges, the writer of Whats Eating Gilbert Grape comments on his wishes for the film he states I would hope that people might view their fellow beings with more empathy, more compassion and a desire to understand (Malony, 2002, p.10). Although an encouraging and optimistic aspiration, the perspective of the film from people with disabilities would certainly be different. The discussion above demonstrates that the representations of disability in Whats Eating Gilbert Grape generates themes of incapability and total dependence on others to survive- Arnie cannot live without Gilbert, and Gilbert is stuck caring for Arnie indefinitely. By analysing the representations of disability presented in Whats Eating Gilbert Grape we can clearly see the negative associations put forward. Livingstone (2004) suggests that as educators we can use such inaccuracies and stereotypical images as assets rather than liabilities (p.119). By studying the ways disabilities are represented in films students can develop awareness of specific disability imagery (Safran, 2000, p.46) and learn about what the causes the stigma and lack of inclusion that haunt the disabled community. Safran (2000) insists when using films in education, it must be done with focused, reflective viewing (p.46) which promotes critical engagement, helping students question the cultural ideals created by the prevailing constructions offered in film (Arndt, 2010). An appropriate educational setting for the use of analysing Whats Eating Gilbert Grape would be in high school. Feldman states (cited in Arndt, 2010) that high school students are able to think beyond the concrete, current situation to what might or could be. Specifically, an effective starting point of a critical analysis with students would involve the deconstruction (Safran, 1998) of Arnies character, identifying the stereotypes portrayed and exploring correct representations of developmental disability. The reaction of the community to Arnie and his disability would also be beneficial to examine. Students would explore how the community views Arnie and what attitudes would be more appropriate to promote acceptance and inclusion. Using films to teach are effective because they are a highly motivational (Brown, 2005; Chellew, 2000) due to their entertainment factor. Whats Eating Gilbert Grape is a popular film with popular actors, and would interest high school aged students. Despite its portrayal of recognised negative stereotypes of disability Safran (1998) admits, it can still be useful in the classroom. The acknowledgment of such stereotypes and prejudices against people with disabilities will help students unlearn (Connor Bejoian, 2006, p. 59) the perceptions and attitudes which justify the differential treatment of a minority group. Through looking at our media, particularly film, it is essential for us to reshape pre-existing views (Chellew, 2000, p. 28) by breaking down the robust ideological attitudes of disability that continue to restrict, inhibit and exclude.

Guyana :: essays research papers

Guyana Guyana is a country located on the northern coast of South America. It is bounded on the north by the Atlantic Ocean and on the east by Suriname. On the south side Guyana is bordered by Brazil, and on the west side is Brazil and Venezuela. Guyana achieved its independence on May 26, 1966 when it broke away from Britain. Land and Resources Guyana has three different major geographical regions. These consist of a belt of soil which ranges from five to forty miles, a dense forest area which makes up about four-fifths of the country and a region of savanna. The country also has many rivers that have some spectacular waterfalls and one river has the highest single-drop waterfall in the world. These rivers are navigable from the sea to about one-hundred miles inland, after that they are no longer navigable due to rapids and falls. Natural Resources The lands of Guyana have many valuable natural resources. Within the lands you can find gold, diamonds, kaolin, manganese and bauxite. If you were to travel a little ways off shore, you could also locate some petroleum. These natural resources are very important in helping out the economy of this poor country. The lands have much resource also found in the vegetation and the forests. The plants and trees are documented for their abnormal size and density. Guyana has an excellent lumber industry, they sell some of the finest greenheart as well as mora. Within the forests are a big variety of wildlife which can range from deer to anteater and a few types of monkeys. The birds are very diverse, they consist of for example sugarbirds, cotingas and manakins all which feed on Guyana's vast array of insects. Population , Education and Culture Guyana has an estimated 800,000 people or on an average of 3.8 people per square mile. Georgetown is the capital and it holds a few hundred thousand people. Being the capital, it is the main port city and holds the major educational institution in Guyana. The University of Guyana is the best higher education and there are many schools throughout the country. In the past few years the country has taken education to much higher level. Guyana was settled by East Indians, many still speak Urdu, Hindu and Tamil dialects. The official language is English. The culture is close to the Suriname and French Guiana than to the rest of South America. All of these various cultures have remained fairly distinct and in today's society each group has its own style of life and culture. Economy In 1966, Guyana was in the early stages of developing its resources.

Yeast Population Lab Report Essay Example

Yeast Population Lab Report Essay Example Yeast Population Lab Report Paper Yeast Population Lab Report Paper The biotic factor being tested here is what effect the temperature of he yeasts environment has on its ability or inability to reproduce efficiently. The lab tests the yeast in three separate temperature settings: a cold temperature (ICC), room temperature (ICC), and a hot temperature (ICC). Here, the independent variable is the temperature of the yeast habitat and the dependent variable is the amount (in ml) of CO gas produced by the yeast. The biotic factor in this experiment is what effect the concentration of the yeast has on its ability or inability to reproduce efficiently. The lab tests three different concentrations of the yeast: add 0. 25 ml, 0. 5 ml, or 1 ml of yeast suspension to the test tube. The independent variable is the amount of yeast concentration added and the dependent variable is the amount (in ml) of CO gas produced by the yeast. INTRODUCTION Yeast is a single-cell fungus that produces carbon dioxide (CO) as a byproduct of cellular respiration. Therefore, the more yeast cells in an area, the more CO they will be able to produce. Yeast has many uses as a common ingredient in many foods and drinks, such as alcoholic beverages like beer and wine, and acts as a leavening agent in baking cakes, bread, and other foods by converting the fermentation sugars in the food into CO. This is what makes the dough in many foods rise while baking. This lab closely monitors a yeast population over a period of 72 hours, with various limiting factors being applied to the yeast population. These are factors that have the potential to greatly influence a populations dynamics, sometimes positively and sometimes negatively. They are generally categorized into two groups: biotic and biotic. Biotic factors pertain to life or living things, and some examples in an environment include predators that can kill or injure an animal of a species, competitors that make it more difficult for one animal to access vital sources like food and water, and pathogens or parasites that can quickly kill or weaken a species. In most cases, the existence of predators is a good thing because it helps to keep the population from becoming unbalanced with the coexisting species living around them. However, if the predator population becomes too large, or if an abundance of new predators is introduced to the area, the population of this species will quickly decrease, and possibly be endangered or, after many years, extinct. In addition, having competition in an environment is important to keeping to well-balanced between plants and animals, but can backfire when there is too much competition, and plant life becomes scarce, unable to support the animals. This is true with all limiting factors: they can have a good or bad impact on a population. On the contrary, biotic factors pertain to non-living things, like sunlight, climate, temperature, and varying amounts of rainfall. For example, rainfall is essential in an ecosystem to hydrate both animal and plant life, and it is necessary for survival. However, too much rainfall at one period of time, or flooding, can wash away and kill many forms of plant life, damaging the populations that rely on plants for food, in turn. In addition, temperature can impact a population like yeast (which is tested in this experiment) positively or negatively. For example, if the yeasts environment is very warm, the yeast will be able to thrive in it. This is due to its activation in warmer temperatures. It is able to reproduce faster and more efficiently in a warm environment, thus producing more CO. However, when placed in colder temperatures, it deactivates and, although it does not die or stop producing CO, this drastically slows down the rate of reproduction and production of CO. Therefore, these factors (both biotic and biotic) can potentially, given the circumstances, greatly impact the dynamics of a population. This labs goal is to demonstrate these effects on yeast populations. Yeast is the most efficient model to demonstrate these population dynamics because it can easily be closely watched and it is a simple organism. Testing multicultural organisms in a lab can be more challenging because many of them possess some sort of rational thinking method that can impact the results in a lab. Yeast is a simple, unicellular organism that has only two intentions in its life: arrive and reproduce. This eliminates any impact that yeasts intelligence could have on the experiment. This is one less control that needs to be worried about. Also, yeasts reproduction is rapid. If the lab were to test a multicultural organism, it would take weeks or even months to get a proper result. Using yeast, the lab only took 72 hours. Furthermore, collecting CO from the yeast is a viable method for determining the population growth of yeast because CO is a byproduct of the yeasts cellular respiration process. As more yeast cells are produced, more CO will be produced because there will be more cells to reduce the gas in the enclosed environment as they respire, as measured through the volume displacement method. A carrying capacity in a population is the maximum number of individuals of a given species that an areas resources can sustain indefinitely without significantly depleting or degrading those resources (Population Size). Once the carrying capacity is reached or exceeded, this will take a toll on the environment as a whole. The resources that support this species would quickly diminish, and any other animals that this species preys on would become endangered because there are too many predators killing them.

Evaluation of Theoretic Structure of Research Paper Term

Evaluation of Theoretic Structure of Research - Term Paper Example sideration of outcomes of the experiment conducted, the authors concluded that conducted imaginary interventions contributed significantly to the reduction of patients’ depression, anxiety, and stress, and improved their comfort. To confirm the statement it is enough to consider the quantity of psychiatric inpatients all over the world: according to the report ‘Mental Health Policy and Practice across Europe: The future direction of mental health care’, approximately 450 million of population undergoes various types of mental disorders at any point of time (Knapp, McDaid, Mossialos, and Thornicroft, 2007). It is not a rare situation when people with mood disorders need to repeat their treatment for several times and although hospitalization provides them with some kind of refuge, it also implies certain limitations on patients’ freedom. Moreover, hospitalization could also cause extra discomfort in addition to that, which is invoked by the illness itself. Taking into account that GI interventions might ease patients’ depression, anxiety and stress factors and improve their health, the method influences essentially on the whole success of mental disorders treatment (Shapiro, 2003).

Menken's Dead Gods - Term Paper Example Take for instance, Huitzilopochtli, who was the national god of the Aztec of Tenochtitlan and the most celebrated and feared of all the gods of the ancient Aztec. The Aztec built a great temple on the Pyramid in Tenochtitlan in his honor. At its completion ceremonies, it is reported that more than 20,000 human sacrifices were offered in a four day celebration (Andrews 224). This attests to position Huitzilopochtli occupied among the ancient Aztec. However, apart from a few savage in the Mexican forest, Huitzilopochtli is as dead as dead great men like General Coxey Richmond P. Hobson because he lives only in history. No one worship or pay reverence to him in any form. He is a forgotten character even among the present day Aztec. Huitzilopochtli is not the only god that is a victim of death. Indeed, the numerous Roman gods and goddesses such as Jupiter and Venus, the Egyptian gods and goddesses such as Isis and Osiris (British Broadcasting Corporation), have undergone similar fate. Ju piter is no longer worshiped by present day Romans nor is Osiris of any relevance to the 21st century Egyptian. The same applies to all the gods mentioned by Mencken. These gods live only in history like great man like Abraham Lincoln. Their temples and place of worship are historical monuments just like the home of Abraham Lincoln is a history monument. Thus I absolutely concur with Menken that these are now dead gods.... In fact, the ability to procreate and response to external influences are the determining characteristics of the living. Indeed, the gods mentioned by Mencken exhibits these traits. Huitzilopochtli, for instance, cannot response if he is insulted or when his temple is abused. He cannot influence events happening around him. A dead god has no influence on present day events. He has lost its place. Like the dead man, he lives only in the mind of his lovers and in history. He does not create anything neither does he initiate ideas. Nobody attributes great inventions and ideas to the gods mentioned by Mencken, at least in our time. A living god is a source of inspiration to its followers. A dead god provides no inspiration. As a result of all the lacks of the dead god as mentioned above, he has no worshippers or followers. Indeed, the trademark of a dead god is his lack of followers and worshipper (Mencken 1). This follows from the dead god inability to influence events and to response t o external events. Why are other gods still alive? To be alive means to respond to changes in the environment, to influences events, to initiate ideas, and to procreate. These are characteristics of the living. Gods are acclaimed to be alive if they are held responsible for events happening in the society. As a result, they attract followers, who flock to their temples to worship. Indeed, other gods are alive because they are still considered to be accountable for events happening in the society. At least their followers held them accountable! This attracts thousands, if not millions, of followers to their place of worship. Take for instance Jesus Christ, who the Christian believed to be God. To the Christians, he
