Essay on Global Warming Essay Example for Free

Essay on Global Warming Essay Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. The 29th century is experiencing a continued increase of Earth’s mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is global warming is affecting the nature’s balance and has a huge impact on life like continued heat waves, and sudden occurrence of storms and floods. Don’t we see time to time the epidemics that are devastating to human life and the flooding of the farmlands that puts economy in a deep hole? Scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from non -stop burning of fossil fuels and the razing of tropical forests. Since the industrial revolution till this day, there is a constant emission of the carbon into the atmosphere, everything we do we leave carbon footprints. It is a man made cause of the global warming. The global emissions jumped 3 percent in 2011 and are expected to jump another 2.6 percent in 2012, researchers reported. The greenhouse effect is a process by which the greenhouse gases absorb thermal radiation; these are then reradiated in all directions. But when some of these radiations come back to the surface and lower atmosphere, it causes increase in the average surface temperature leading to global warming. Global warming Causes The causes are many of which the main culprit is the increase in the greenhouse gases that is produced by burning fossil fuel and deforestation, thus intensifying the greenhouse effect leading to global warming. The four main contributors of the greenhouse effect are, water vapor, carbon dioxide, methane and ozone. Mining for coal and oil releases methane in the atmosphere. More ever the leakage from natural gas fields and landfills are additional source of methane. Excessive cutting down of the trees is another factor causing global warming. When deforestation happens the efficiency by which carbon dioxide is stored and oxygen released by the green plants are decreased to a huge rate in turn causing increased concentration of carbon dioxide that leads to increased greenhouse effect. The nitrous oxide from fertilizers, gases used for refrigeration and industrial processes are other factors that cannot be forgotten as the cause of Global Warming. Another source of methane is methane clathrate, a compound containing large amounts of methane trapped in the crystal structure of ice. As methane escapes from the Arctic seabed, the rate of global warming will increase significantly. Ice caps and glaciers reflect sunlight, bouncing high temperature sun -rays back into space away from the Earth. When these icecaps are removed the earth gets warmer as the dark oceans absorb much thermal radiation from the sun. Some regions may be wet with rain and some areas will suffer drought due to global warming. The climatic changes happen due to global warming. Seasonal changes are unpredictable unexpected thunderstorms might result as mentioned earlier. The burning of wood (should be reduced to a greater extent) releases oxidizable carbon to the atmosphere whose presence in greater amount causes the elevation of temperature. There is strong evidence that emissions of chlorofluorocarbons (CFCs) were the major cause of the recent abnormal warming. Like carbon CFC do not trap heat but in the presence of UV rays the chlorine gets detached from CFC, drifts up into the stratosphere and these unattached chlorines catalytically convert Ozone molecules into Oxygen molecules depleting the ozone layer.

Video Games: Positive Agents Of Change Essay -- Video Games Essays

Video games have come under fire recently. Many people claim the graphic violence and adult themes in the games have affected younger generations and caused many violent acts. Others claim that video games have contributed to obesity and a lack of communication skills. Both of these claims are most often an older generation's misunderstanding of today's youth and the overreaction of the media. Rarely does the mainstream media portray video games for what they really are, a new way for kids to interact and share meaningful experiences all without being in any danger. Video games have endless possibilities and should be thought of as tools to teach the youth rather than the cancer that ravages them. Although many people see video games as a problem, they are actually a positive force because they have infinite possibilities for good. Video games have become one of the most popular pastimes for kids these days. With the advent of powerful graphics processors and more innovative chip designs, games are becoming incredibly realistic. This realism is what brings many gamers to the industry. Realism, in a sense, is why the gaming industry has taken off and increases profits every year. Video games are not just a fun hobby or pastime, they are way for gamers to escape the world and imagine themselves in an entirely new landscape. Video games are dreams with controllers. While driving through a racetrack in a video game, one doesn't feel as if they are sitting in front of a TV playing a game, they feel as if they are the car. This is a hard phenomenon to explain but video games are such a global activity inside the brain that the user actually feels as if he is in the game living the experience. This, is obviously lim... ...deo games are a great way for kids and even adults to get away from the world for a while. Players are wrapped up in their own virtual world and can express how they are feeling through the game. Video games can also have great positive side effects and could even be the training mechanism of the future for many professions. The people who argue against video games on the grounds of violence and desensitization misunderstand the attitude of children toward video games and imply that humans are no more complicated than â€Å"monkey-see monkey-do.† Video games still have a lot of potential and they can be used for much more than just relaxation and fun. They can be a social medium, an agent of change. A good video game can be like a work of art that inspires people to try new things or change the way they think about something. But above all else, video games sure are fun.

Oppositional Defiant Disorder

Oppositional Defiant Disorder: Case Study and Research Samaritan L. Carlo Suffolk County Community College SYS 213, Exceptional Child Able Keller is an English-speaking and physically healthy four-year-old boy. He lives with his mother and eighteen-year-old sister, and attends preschool during the week. Babel's mother works seven days a week and he is supervised on the weekends by a nanny. His current nanny began working for the family fairly recently; the two nannies prior to her both worked for less than two months before quitting.Babel's parents have been divorced for two years. His mother is his primary care-giver and is father sees him infrequently. Lately, Babel's mother and preschool teacher have been unable to cope with his disruptive and distressing behaviors. Babel's teacher estimates that his disruptive behaviors began at the beginning of the school year, which was approximately eight months ago; his mother says that the behaviors began roughly one year ago and have been i ncreasing in severity and frequency since then.Babel's sister has also voiced concerns regarding her brother's spiteful actions towards her due to the strain his recent behaviors have put on their relationship (PAP, 2013). Babel's mother reports that Able cannot go more than two days without becoming extremely irritated with necessary daily tasks. Once, Babel's mother requested that he go wash his hands before dinner. Able became irrationally frustrated, blatantly refused to wash his hands, and began lashing out in a manner which she describes as â€Å"one of his tantrums. Babel's mother also describes an instance in which their last nanny was on the receiving end of Babel's disruptive behavior. The nanny took away Babel's toy at his refusal to brush his teeth and get ready for bed, and later found her toothbrush in the toilet boil. After further acts of blatant defiance by Able, the nanny resigned and Babel's mother was forced to find a new nanny. Able exhibited a similar behavior towards his sister when she asked him if he could grab her a pencil for her homework. Able was instantly irritated at this request and yelled â€Å"Don't tell me what to do! He then proceeded to rip up her homework and run to his room. According to his mother, destruction of property in such an aggressive manner has been very infrequent in Babel's behavior. However, his spitefulness resulted in the loss of a nanny and his sister's increasing emotional sisters that her â€Å"sweet baby brother† has taken on such a resentful attitude towards her (PAP, 2013). Babel's preschool teacher told his mother that his behavior will no longer be tolerated and recommended that he be assessed. His teacher explains his behaviors in class as â€Å"defiant and disruptive. Almost daily, he actively ignores class rules, such as not talking during reading time, and becomes even more defiant when his violations are addressed by the teacher. His teacher has paused class multiple times to stop hi m from distracting either the whole class or individual students. She ports that the most troublesome aspects of Babel's behavior are the frequency of the disruptions and his responses to being reprimanded. Once, when a classmate went to the teacher after Able ignored her plea that he stop poking her arm, Able became outwardly more motivated to continue poking her relentlessly.When his teacher explained why his behavior is unacceptable, Able accused the classmate that he had been poking of initiating the incident and provoking him by being â€Å"annoying. † Babel's teacher reports that he has yet to accept blame or responsibility for any of his misdoings and that he is often ostracizes by his peers. Classmates have called him â€Å"annoying† and † a tattle-tale. † Teachers discourage this taunting behavior, but the discrimination has led to further emotional distress within Able which has been exhibited by more frequent moods of frustration and irritability at home (PAP, 2013).Babel's behavior has been extremely distressing at home and in school over a duration of at least eight months, but has not presented a problem elsewhere thus far. His teacher has felt stress due to her inability to get him to obey rules, a lack of time to address his disruptions, and phone calls from parents whose children claim to have en harassed in some way by Able. His sister has become distraught over his behavior and his mother has been put under enormous pressure to maintain a trustworthy and reliable nanny.Due to the duration of his irritable, defiant, and occasionally vindictive behaviors, which have occurred at home and at school, have had negative consequences in his academic, social, and emotional functioning, and have caused distress for several people in his life, Able has been diagnosed with Oppositional Defiant Disorder of a moderate severity. Babel's defiant, argumentative, ND vindictive symptoms put him at risk for developing Conduct Disorder, and his increasing emotional distress due to peer issues at school increases his risk of developing an emotional disorder (PAP, 2013).Recent research of oppositional defiant disorder (ODD) is characterized by the emergence of two themes: developmental precursors to the disorder and the dimension of irritability. The study of precursors to ODD are discussed by Tinfoil and Malta (2013) in their research study which examines the relations between interpretative understanding, moral emotional attribution, and sympathy with the ability to predict ODD symptoms.Burke, Babylon, Rowe, Duke, Steep, Hippies, and Walden (2014) discuss varying dimensionality models of ODD, the identification of irritability by certain symptoms, and the implications of the results for further research on ODD. Tinfoil and Malta (2013) suggest that the limited success of current ODD treatments may be attributed to the lack of empirical research on the disorder's developmental antecedents. Their research responds t o this insufficiency by assessing supposed key components in the genesis of antisocial behaviors: social-cognitive development and moral emotions (Tinfoil & Malt', 2013).The study analyzes a sample of 128 four- and eight-year-old children with ODD and investigates the links between the symptoms of ODD and interpretative understanding, or theory of mind skills, in children (Tinfoil & Malt', 2013). The research of Tinfoil and Malta (2013) also analyzes ODD symptoms in relation to sympathy and moral emotion attribution (MEA), and examines the mediating role that each of these may have on each others' development. The participants of the study include 128 English-speaking children and one caregiver each parent assessments (Tinfoil & Malta, 2013).The only exclusion criterion is a hill with autism spectrum disorder, and the ethnicities of the participants vary (Tinfoil & Malt', 2013). Symptoms of ODD in the children are rated by caregivers using ADSM-oriented scales, interpretive understa nding ratings are obtained by professionals using the Landed and Chandler's puppet activity, sympathy is measured by caregiver and child self-reports, and MEA is evaluated using each child's negative or positive responses to the presentation of hypothetical vignettes of varying lapses in morality (Tinfoil & Malt', 2013).The procedure of the research study involved each child and their caregiver attending one session at the research ABA, the parent providing written consent and the child providing oral agreement, and the child being interviewed for a duration of approximately forty-five minutes by psychology undergraduate students (Tinfoil & Malta, 2013). The caregiver for each child filled out the symptom questionnaires outside of the interview room during the process (Tinfoil & Malta, 2013). Tinfoil and Malta (2013) find that interpretive understanding, sympathy, and MEA all influence ODD symptoms.Ratings of child sympathy by the caregivers play a mediating role on the effect of in terpretive understanding on ODD symptoms, and MEA strength significantly influences interpretative understanding in the domain of rule violation (Tinfoil & Malt', 2013). The research of Tinfoil and Malta (2013) indicates the necessity of further research on social-cognitive and affective-moral factors that could potentially precede ODD and help with early prediction, and highlights a possible origin of the rule-violating behavior so prevalent in Babel's case as a deficit in MEA.Recent research on ODD also focuses on the importance of irritability and on reaching a consensus regarding which symptoms best identify irritability (Burke et al. , 2014). Burke et al. (2014) introduces the study by explaining how existing data purports that symptoms of ODD represent a unidirectional assembly and are distinct from those of other disorders. Recently, studies have found conflicting evidence regarding the dimensions ODD symptoms are categorized by, which questions the reliability of assessment using the existing ODD model (Burke et al. 2014). Also, inconsistencies exist concerning which symptoms of ODD comprise which dimensions (Burke et al. , 2014). Burke et al. (2014) suggests that a factor model of the disorder may help solve these conflicts surrounding the concept of diagnostic irritability. The study tests single and multi- dimensional models of ODD including factor and competing models, analyzes various elements of measurement within symptoms, and aims to identify the extent to which specific dimensions relate to each other and general ODD symptoms (Burke et al. 2014). The study also attempts to determine if there is a distinguishing dimension of irritability within ODD, if one model of ODD is superior to all other models, and if there is an additional general dimension of ODD (Burke et al. , 2014). ODD symptom data of five community samples of five- to eighteen-year-old boys and arils is evaluated by Burke et. Al (2014) using assorted measurement scales and care- g iver reports.Methods of assessing symptom presence, frequency, and severity are the Revised Diagnostic Interview Schedule for Children, Parent Version, Child Symptom Inventory-4, Child and Adolescent Psychopathology Scale, Developmental and Well-Being Assessment, and Emory Diagnostic Rating Scale (Burke et al. , 2014). The data is analyzed using five models of ODD dimensionality and two models of irritability, which identify irritability as either touchy, angry, and spiteful, or touchy, angry, and frequent loss of temper (Burke et al. 2014). Burke el al. (2014) concludes that the best model for symptoms of ODD is a general factor model in which irritability and oppositional behavior factors exist alongside a general ODD factor, and in which irritability and oppositional behaviors significantly correlate with each other (Burke et al. , 2014). This model is consistently better across multiple samples and is made up of eight general ODD items, each correlated with either an irritabilit y or an oppositional behavioral dimension (Burke et. Al, 2014).The irritability mission includes temper, touchiness, and anger; the oppositional behavior dimension includes argumentativeness, defiance, annoyance, balefulness, and spitefulness (Burke et. Al, 2014). Burke et. Al (2014) also finds that irritability is most accurately characterized by touchiness, anger, and temper loss. The implications of the results are the emergence of strong evidence for a multidimensionality within ODD, and support for an identification of irritability characterized by loss of temper, touchiness, and anger (Burke et al. , 2014).Although the research is unable to answer attention questions regarding the existence of a third dimension, the initial questions are addressed concerning the underlying structure of symptom dimensions and provide evidence for a superior set of characteristics of irritability (Burke et al. , 2014). Lastly, Burke et al. (2014) addresses that possible limitations in the study were due to the variability of the questionnaires, the variability of the scaling systems, and the different research structure for boys and girls in the samples.

The Sun Also Rises And Hills Like White Elephants

Charles Padial Professor Anderson Literature October 31, 2015 Essay 1 Ernest Hemingway has a very unique style of writing. He captures the readers’ attention with strong imagery, metaphors, and symbolism. In both the Sun Also Rises and Hills Like White Elephants, Hemingway uses a simple writing style that allows the audience to have a clear image of the main argument. The reader must pay very close attention to the dialogue, as different subliminal messages are exposed throughout the story. Also, in both stories the women protagonist is the main source of the argument. In Hills Like White Elephants, Hemingway tells a simple story about a couple who is arguing about an abortion. Through the woman’s dialogue, the readers grasp that she does not want to get the operation done, even though she never states that directly. As the man tries to convince her, she, obviously, becomes more and more frustrated with him. For example the woman says, â€Å"I feel fine. There’s nothing wrong with me. I feel fine†(478). From this dialogue, the reader can acknowledge that the woman by no means is going to give into the man’s persuasion and, ultimately, the final decision will be hers. However, the man does not seem to care that the operation could potentially harm the woman. For example, he describes the abortion, â€Å"It’s really an awfully simple operation, Jig. It’s not really an operation at all†(476). The reader grasps that the man is selfish, does not put himself in the woman’s shoes, andShow MoreRelated Ernest Hemingway s The Sun Also Rises1353 Words   |  6 PagesHemingway creates The Sun Also Rises to do both jobs.
