Fetal Alcojhol Syndrome Essays - RTT, Teratogens, Alcohol And Health

Fetal Alcojhol Syndrome Fetal Alcohol Syndrome Fetal Alcohol Syndrome (FAS) refers to a group of physical and mental birth defects resulting from a women's drinking alcohol heavily or at crucial stages during pregnancy. Fetal Alcohol Syndrome was first named and treated in the late 1960's. This condition results from the toxic effect of alcohol and its chemical factors on the developing fetus. FAS is the leading cause of mental retardation occurring in 1 out of every 750 births. The frequency of FAS occurs about 1.9 times out of every 1000 births according to the latest figures, and minor effects can be seen in up to 20% of pregnancies per year. This number changes drastically for women who are clearly alcoholics. As high as 29 children out of every 1000 births will suffer from FAS if the mother is an alcoholic. The overwhelming consistency of this disease is that it is 100% preventable if a mother would drink no alcohol while pregnant. There are three major effects or hallmarks of drinking while pregnant. First, alcohol will cause pre- and postnatal growth retardation for the baby. Second, alcohol can cause central nervous system dysfunction and neurodevelopmental defects for the child. The third consequence of drinking while pregnant causes facial disformaties. Studies comparing children of women who drank continually throughout their pregnancy with women who abstained from drinking that alcohol exposed offspring were smaller in weight, length, and head circumference. The greatest effect of FAS appears to be the overall size of an alcohol-exposed child. Children exposed prenatally to alcohol continue to be smaller than their non-exposed peers. A study has shown that there is a relationship between alcohol exposure during the second and third trimesters and growth at 8 months, 18 months, and 3years of age. Children exposed to an average of one drink per day or more during the second or third trimester were signific antly smaller in weight, length, and head circumference when compared with children who had not been exposed to alcohol. Children that were exposed to less than one drink a day were smaller than the non-exposed children but larger than the more heavily exposed children. The attempt to understand FAS has lead to new areas of research attempting to discover the mechanism that causes defects. As of now the exact mechanism is not known. One theory suggest that alcohol increases placental contractility and thereby decreases oxygen supply to the growing embryo. A lack of necessary oxygen to a growing brain is no doubt the result of alcohol's work but exactly how it happens is still under investigation. In the United States, epidemiological data suggest that the rates of FAS tend to higher in African American and Native Americans than whites of similar socioeconomic status. A survey complied by the centers for disease control and prevention reviewed more than 4.6 million births in approximately 1,200 hospitals and showed considerable differences in occurrence of FAS among racial groups. The reason for variance among these groups remains unclear. Among Native Americans, rates of FAS even varied between the different tribes. This may be attributed to nutrition, fertility, or metabolic differences in the genetic makeup of each tribe. Also Native American family culture can influence drinking patterns often leading to a higher rate of alcohol consumption. Among factors to consider, alcohol consumption is frequently associated with drug abuse, smoking, and malnutrition. All of these factors can cause serious harm to the developing embryo of a child. It is difficult for researchers to decide which effects are caused by alcohol alone. To clearly distinguish a child as having FAS poses a difficult thing for researchers. They soon began to realize that they were encountering children with some, but not all the classical signs of FAS. Because a diagnosis of FAS demands the presence of all three hallmarks, (growth deficiency, central nervous system dysfunction, and physical abnormalities) a term was developed to refer to children with what seemed to suspected fetal alcohol exposure. The name to these occurrences is Fetal Alcohol Effects (FAE). This is not intended to be a diagnosis but rather a bookmark suggesting that the abnormalities seen in children were comparable with FAS. To date, there is no universal accepted evidence that FAE is definable

The byzantine in 1000 AD essays

The byzantine in 1000 AD essays For many years a taboo subject for all but a small number of specialists primarily in the fields of history and political science, and treated as an aberration in discussions of 'Western Culture', fascism has returned with a vengeance. The resurgence of extreme right wing and neo-fascist movements in Europe and throughout the world in the last fifteen years have, of course, played a major and indeed chilling role in this 'return'. So too, have revelations concerning fascist involvements on the part of major intellectual figures and artists whose work has had a profound inßuence in shaping modern and postmodern culture. Fascism, in short, can no longer be considered a short-lived aberration but must be dealt with as an ongoing presence in our cultural and political heritage. Richard GolsanÕs talk will pursue these observations and attempt to assess why fascism remains a scandal, which we are still not able to cope with culturally or politically. The Spectacular State: Fascism and the Modern Imagination is a public forum happening in which brings together artists, activists, and scholars to generate critical discussion about the various characteristics and consequences of fascism in its historical and contemporary contexts. The forum will include film and video screenings, art exhibitions, lectures, panels and roundtable discussions at a number of different venues. There are many reasons why a public forum dedicated to the critical examination of fascism is especially urgent. The most immediate and obvious is the resurgence of neo-nazism and the extreme right, and the subsequent need to understand how these movements operate so that they can be more effectively resisted. Nineteen ninety-five marks the 50th anniversary of the end of the European Holocaust and the beginning of international recognition of its crimes and atrocities. Although this part of hist ...

Violence Research Paper Example | Topics and Well Written Essays - 2250 words

Violence - Research Paper Example Regardless of what argument a person takes, â€Å"Call of Duty† should be an adult game that is only played by people over the age of 18 or young people who have reached the moral stage of development that understands right from wrong. A 1994 survey of young students, between fourth and sixth grades, showed that the longer a person plays a video game the more their personal empathy for others was reduced (Funk, Baldacci, Pasold & Baumgardner, 26). Empathy is the level of personal respect and emotional attachment that a person has to the needs of others in society. This study suggests that if a child were to play â€Å"Call of Duty† for a long period of time, and be exposed to ongoing brutal images, they will be likely to adopt personality traits that make them less caring about others. This theory offers that young people will become desensitized after prolonged periods, making them less teamwork focused and able to support others in the community with positive emotions. In my personal life, I have watched many young children playing violent video games, including â€Å"Call of Duty†. Some of these children were between the ages of eight and 17 years. I have seen children who get very involved with the content of the game, and will explode verbally when they fail to meet content targets or achieve the game’s goal. One young child, a family friend of age 12, actually would slam the computer mouse down on the counter and swear at the computer when playing the game. This was something that was not common with this child when in other social environments. This would add support to the idea that it can change the personality behaviors of children when they play the game over and over again. A normally content and non-explosive child who, when exposed to violent game play, begins to act uncontrollably and angry should be an

Visual Effects - Assignment Example The principles of the visualization illustrate content focus. The visualization concentrates on illustrating how HAI is contracted. Data visualization 02 is studied through the common dash board mistakes of Stephen Few. The data arrangement is poor (Edward 93). This is because four bar graphs and one pie chart are squeezed in one slide page. This minimizes visual clarity. There is also poorly highlighting of the most important information. This is because a lot of information is illustrated in a single page, leading to confusion. Data visualization 03 is analyzed through the excel dashboards. Excel enables effective illustrating of statistical data through graphs, tables and charts (Edward 36). The top hashtags and top mentions are summarized accordingly through the bar graphs. However, illustrating a lot of visual information in one page is not desirable, as it may confuse the audience. The dog images are illustrated through the analytical designs principles.

Cultural diversity in America Essay Example | Topics and Well Written Essays - 1250 words

Cultural diversity in America - Essay Example Culture influences basically in the way of behavior, way of living, and way of speech. It is a habit formation that takes place when one grows in a particular society and the innate quality to learn from his surrounding in order to cope up with his environment is the unique part of character inherent in human being which develops while growing in the community. Culture has substantial influence in groups and individual each human is the product of the culture where he lives that even has an unconscious influence on each human it has become human identification. Most of the society has their own culture and are proud of its culture, and when two or more cultures come in contact together there arises a diversity in that culture. United State is highly enriched with cultural diversities as people from all over the world settled here leading to cultural differences. Most of Americans face cultural differences in their life. Globalization brought the world together and with the development of global economic system and the rise of international cooperation and business community has helped to bring people from all over the world with different cultures into face-to-face contact. It has been a providing shelter for every one, hence people from all over the world are migrating to America, and America is a nation with diverse cultures and has always taken pride in their diversity. Culture has always attracted anthropologists, educators, historians, and sociologists to explore various aspects of culture and its implications in their field. The dive rsity of culture also brought conflicts between various cultural groups and caused various social problems. Cultural diversity in America has been a matter of debate and people from different cultures face problems in schools, colleges, universities, institutions, government and business circle What constitutes race and ethnic character of human is the out ward physical and

Disadvantages Of Arv Treatment Health And Social Care Essay

Disadvantages Of Arv Treatment Health And Social Care Essay Herbs have been used extensively in hopes of improving immune response and reducing symptoms. No known herbal remedy has been shown to cure AIDS or even reduce chances of AIDS-related infections. Still, some herbs can be worth trying if used safely and in consultation with a qualified practitioner who not only understands herbs but also has experience treating AIDS and HIV infection. Immunity-boosting herbs (such as Astragalus, Echinacea, and Ginkgo) may help revive an ailing immune system, and certain herbs (such as Garlic) may help battle bacteria and viruses. Deglycyrrhizinated licorice can soothe the mouth and throat ulcers that often accompany full-blown AIDS. Unfortunately, there is no known scientific explanation yet, for how herbs have these powers in treating AIDS and the only information available about how useful herbal treatments and remedies can be, is based on the knowledge gained from people living with HIV/AIDS. This means that not all herbs and remedies have the same effect on all people. Some communities have their own knowledge of health and nutrition, based on local traditions and culture. This may complicate the administration of herbal remedies from region to region, as the fundamental factor is now depending whether the patient is willing to cross cultures in order to obtain treatment. In some extreme cases, any external medical recommendations that a patient may receive is compared with their cultural practices and the recommendations of their traditional healers. Patients will only take action if the recommendations they receive appear to make sense and provide some benefit. Ironically, some traditional beliefs and food practices may not be useful at all, judging that a herb like Garlic root should work whether the patient is of Chinese or African descent. Patients with HIV/AIDS often become frustrated with management of the disease and are willing to try anything in the hope of staying healthy and living longer. One of the greatest disadvantages is that HIV/AIDS is not a traditional illness and so far, there is no hard evidence to believe that traditional medicines or herbal remedies can treat HIV and cure AIDS. However, certain herbal medicines may help to treat many of the symptoms of opportunistic infections that are part of AIDS. While some of these medicines may be undoubtedly helpful, others may be dangerous as they may do more harm than good. This happens when the patient mixes pharmaceutical drugs and herbs resulting in contra-indications or when they take certain foods that should be otherwise avoided. The notion that herbal medicines are natural and therefore safe is as widespread as it is misleading. Some of these remedies have been associated with severe adverse effects caused by the toxicity of the herbal ingredients. Others may cause problems because of contamination or adulteration [9]. Herbs and spices should be used in moderate amounts. Exceeding these amounts may cause problems and have a toxic effect; moreover, the function of the herbs and spices will not be increased. Herbs do not replace healthy eating and should not be used in place of a healthy and balanced diet but they do retain the bodys natural pH (alkaline) and this in turn, as discussed before, forces the microzymes to stop mutating into bacteria, viruses and funguses that cause opportunistic infections. 2.1.7 Advantages of Herbal Treatment: On general note, Herbal therapies seek to boost patients immune systems, inhibit opportunistic infections, alleviate symptoms, and inhibit HIV itself. Herbal medicines are very cheap in comparison to the conventional form of medication Herbal medicine helps the body to maintain its natural pH, which is alkaline; this in turn starves and inhibits all adverse microzymes from growing or mutating. Herbal medicines can be consumed without the aid of any kind of prescription, although a herbal or medical practitioner has to be consulted prior Herbal medicines are known to be more productive in comparison to other forms of medication in curing certain conditions. Herbal medicines offer long lasting benefits in terms of overall wellness. In certain situations, Herbs are considered a possible means to minimize drug side effects. Unlike with the convectional highly active antiretroviral therapy (HAART), herbs do not need to work in combination in order to get effective results Herbs are readily available and once a patient knows which herb to use, he/she can grow their own. 2.1.8 Disadvantages of Herbal Treatment: Curing period is usually longer in comparison to conventional medication Drug-interactions can be hazardous to a patient ,if they decide to mix herbs and drugs Herbal medicines are known to be ineffective against serious ailments Herbal medicines are taken without prescription which means that in some cases, individual might be undergoing a trial and error process with their medication. Herbal medicines can cause allergic reactions in some cases Herbal medicines will not eliminate the HI virus out of the body Most governments do not approve of any kind of herbal medication. Its usually consumed upon the persons own risk, and when it comes to branded herbal supplements one cant expect any kind of quality assurance 2.2 Expert Systems and their use on the Internet 2.2.0 Expert systems An expert system is a computer program that incorporates concepts derived from experts in a field, uses the available information, heuristics and inference to suggest solutions to problems in that particular discipline or give advice. An expert system should have good decision making, this is strongly dependent on various capabilities that include the effective acquisition, storage, distribution and sophisticated use of the human experts in the field in question. The most widely used way of representing domain knowledge in expert systems is as a set of production rules which is also how humans generally infer decisions. Expert systems were made to provide knowledge and advice to a larger number of users than one user. An Expert system can be viewed as a teaching tool because it is equipped with the unique features which allow the users to ask questions on how, why and what format, expert systems also allow automation of many tasks that could not be effectively handled by human experts. In addition, an Expert system attempts to emulate how a human expert solves a problem, mostly by the manipulation of symbols instead of numbers. As a result because of the low cost per user and automation of numerous tasks ,expert system making has become very attractive and in the long run is much cheaper than getting human expert advice, its development is however relatively costly but its operation is easy and quite cheap. Maintenance is easy as well because once an expert system is developed it is simple to add new information to the knowledge base and new rules can be developed. 2.2.1 Advantages of Expert systems Availability: The expert system is always available 24 hours a day and will on no account tire Can capture scarce expertise, collected from a number of experts and integrate their opinions. Consistency: The computer does not make common futile human mistakes such as forgetting, getting drunk or strike when it is most needed. Data can be kept up-to-date. Efficiency: Expert systems have an increased output and productivity as well as decreased decision making time. Flexibility: Expert systems can operate in hazardous environments. They can also work with incomplete or uncertain information. Scalability: The system can be used at a distance over a network therefore can reach a large population. The computer can store far more information than a human expert. 2.2.2 Disadvantages of Expert systems Expertise can be hard to extract from humans Expert system users have natural cognitive limits (therefore can not perform as perfectly as a human) Experts vocabulary is often limited and highly technical Expert systems may not be able to arrive at valid conclusions and sometimes produce incorrect recommendations Knowledge is not always readily available Lack of trust by end-users Most experts have no independent means to validate their conclusions 2.3 Structure of Expert systems A typical expert system consists of: A knowledge base; this contains the specific domain knowledge that is used by an expert to derive conclusions from facts The inference engine, which is responsible for using the rules and facts to derive conclusions whether it is through forward, backward chaining or a combination of both. An explanation system, which provides information to the user about how the inference engine arrived at its conclusions A fact database, which contains the case-specific data that are to be used in a particular case to derive a conclusion and A User interface, which provides access to the inference engine, the explanation system, and the knowledge-base editor. KnowledgeBase Fact Database Expert System Shell Inference Engine Knowledge Base Editor Explanation System User Interface User Figure2.1 A basic structure of an Expert System. An Expert System can be rule-based, frame based or both. In a rule-based system, the knowledge base is a database of rules. Rule-based systems are computer systems that use rules to provide recommendations or diagnoses, or to determine a course of action in a particular situation or to solve a particular problem. Its line of reasoning or the inference engine technique can be forward chaining, backward chaining, or a combination of both and the Rete algorithm. 2.4 Inference Engine The knowledge in the knowledge base is used for reasoning and inferring conclusions. An inference rule is an abstract structure that contains a set of rules that mathematically delineates a (usually infinite) set of finite length strings over a (usually finite) alphabet. It is a two part structure using First Order Logic for knowledge representation. If then The brain of expert system is the inference engine which is generally a large number of rules and facts. The inference engine matches facts and data, which is in the fact database against the inference rules to infer conclusions which result in actions. The process of matching the new or existing facts against inference rules is called Pattern matching. Pattern matching in the inference engine can use any of the following algorithms: Linear Rete Treat Leaps Most of the rule engines under study implement and extend the Rete algorithm. Leaps is also used widely but is questionable due to poor maintenance. Rete based engines have proprietary enhancements to the Rete algorithm like RetePlus, Rete III and ReteOO. The Rete algorithm is responsible for ensuring that there is a clear distinction between rules and facts in the database. This algorithm takes the form of a network, with nodes and paths. Each path from the root node to a leaf in the tree represents the left-hand side of a rule. Each node stores details of which facts have been matched by the rules at that point in the path. In situations where new data or facts are added, it means the Rete algorithm will propagate and change data stored at the node accordingly. In this way, the system only needs to test each new fact against the rules, and only against those rules to which the new fact is relevant, instead of checking each fact against each rule. 2.4.1 Methods of Inference Engine execution There are two methods of execution for rule based expert systems, forward chaining and backward chaining. And systems that implement both are called hybrid production rule systems. 2.4.2Forward Chaining This is a data driven and thus reactionary method. When applying forward chaining, the first step is to take the facts in the fact database and see if any combination of these matches all the antecedents (conditions) of one of the rules in the rule database. When all the antecedents of a rule are matched by facts in the database, then this rule is triggered. Usually, when a rule is triggered, it is then fired, which means its conclusion is added to the facts database. 2.4.3 Backward Chaining This method is goal driven, meaning that we start with a conclusion which the engine tries to satisfy. An inference engine using backward chaining would search the inference rules until it finds one which has a then clause that matches a desired goal. If the if clause of that inference rule is not known to be true, then it is added to the list of goals. Searches for sub goal conclusions begin, in hopes that, that will help satisfy some part of the current goal. It continues this process until either the initial conclusion is proven or there are no more sub goals. 2.5 Expert system shells Expert systems can be built that contain all the useful methods without any domain specific knowledge. These systems are called skeletal systems, shells or Artificial intelligence tools. The interpreter is separated from the domain-specific knowledge and thus creating a system that could be used to construct new expert systems by adding new knowledge corresponding to the new problem domain. Examples of shells include CLIPS, eGanges, OPS5, ART, JESS, and Eclipse. 2.6 Systems currently in use 2.6.1 Expert System for HIV/AIDS information The above expert system was created under the motivation of a Microsoft sponsored project called IHISM, which aims to contribute to the digital divide by developing an HIV and AIDS public information portal accessible through mobile phones [10]. The Expert system was tailored made with reference to Botswana, according to UNAIDS estimates, HIV/AIDS has affected every segment of Botswana society and one-third of Botswanas sexually-active population between the ages of 15 and 49 (out of a total population of 1.5 million) are infected with the virus, which is the highest rate in the world [11]. The information service portal would allow the public to request for information on topics related to HIV and AIDS such as descriptions, infection, testing, counselling and support, opportunistic diseases and paediatric care etc. The portal represents this information in the form of Frequently Asked Questions (FAQ) service where the user inputs a query on any of the subjects. The system is meant to act as an online expert in HIV and AIDS information such that, some information may have to be derived through inference as opposed to simple data retrieval. The system is to accept as input a FAQ from the user and provide the most relevant answer to the question. Challenges of the system: Users may ask the questions differently in pursuit of the same answer System should be able to systematically analyse the questions and provide an appropriate answer System should be able to determine the various forms in which a typical FAQ question could be mapped to the relevant answer. Participants agreed that the expert system was not only easy to use 2.6.2 A Self-Learning Fuzzy Discrete Event System for HIV/AIDS Treatment Regimen Selection The HI virus mutates often and so a patient has to be frequently changing their medication course. And because of the strict drug adherence guidelines, it therefore becomes desirable to have a treatment- decision support system that is capable of self-learning. Basing on the fuzzy discrete event system (FDES) theory, a self-learning HIV/AIDS regimen selection system for the initial round of combination antiretroviral therapy, which is one of the most complex therapies in medicine, was developed [12]. The system consists of a treatment objectives classifier, fuzzy finite state machine models for treatment regimens, and a genetic-algorithm-based optimizer. System focuses on the four historically popular regimens with 32 associated treatment objectives involving the four most important clinical variables (potency, adherence, adverse effects, and future drug options). Advantages of the A Self-Learning Fuzzy Discrete Event System for HIV/AIDS Treatment Regimen Selection: Higher flexibility and scalability Easier knowledge upgrade for accommodating fast treatment strategy evolution with minimal system modification. Challenges of the A Self-Learning Fuzzy Discrete Event System for HIV/AIDS Treatment Regimen Selection: Patient-specific medical simulation raises several moral, ethical and policy questions that need to be answered before the methodologies can be put to widespread use. 2.6.3 A grid-based HIV expert system This system is for physicians to provide an adaptive interactive advice on treatment applied to drug resistant HI virus. Its knowledge base comprises of distributed data from infectious disease patient databases, literature on in-vitro and in-vivo pharmaceutical data, mutation databases, clinical trials, simulations and medical expert knowledge. The research uses a variety of statistical and numerical methods to identify relationships between HIV genetic sequences and antiviral resistance to investigate consistency of results. Access to and integration of data is done through existing Internet servers and emerging grid-based frameworks like Globus [13]. Advantages of the grid-based HIV expert system: Cellular automata-based simulations are used to predict the drug behaviour overtime Limitations of grid-based HIV expert system: Little data privacy. Sensitive clinical information is often kept on highly secure hospital networks 2.6.4 HIVPCES: a WWW-based HIV patient care expert system Diagnosing HIV-patients and prescribing the correct drug regimen can be a complex task whose outcome is dependent on a large number of variables. The cost of an incorrectly administered drug even for a very short time can be enormous; the HIV virus has specific drugs that can manage its growth at different levels of its life cycle. HIVPCES is a WWW-based HIV patient care expert system. It is an interactive expert system to diagnose HIV patients, and is managed centrally and accessed either as part of an intranet, or as an Internet site.781273 The user interface has been carefully designed to provide a high-level of interaction and therefore improve some of the current limitations of Web applications. The system comprises three modules: (1) A patient self-monitoring personal diary, to create a follow-up patient record; (2) A data analysis and visualisation tool; and (3) A section to allow patients to ask for advising and remote doctor support. abstract Advantages of a WWW-based HIV patient care expert system: Provides health professionals with new means for tele-monitoring and tele-caring patients. Limitations of a WWW-based HIV patient care expert system: Low system security Users anonymity features are required but hard to incorporate in this clinical domain. 2.7 Outline of proposed system In the vast world of medical expert systems there is little attention given to HIV /AIDS and when the topic does get acknowledged, little focus is put into the treatment and much more attention on the common FAQs about the virus. This system aims to center on HIV/AIDS suffering patients and offer advice on supplementary natural treatments such as herbal medicines that these patients can use. Unlike some of the current existing systems, which look at drug adherence plan, i.e. narrowing the users down to only, those on the HAART program, the proposed system can be used by patients whose CD4 count has not yet plummeted therefore allows the patient to have a informed decision on how to maintain a healthy life and have a boosted immune system. Proposed system will offer information on particular herbs, that is, the name, healing effects and the contra-indications and explanations for every herb it advises. Advantages of proposed system: Caters for both physicians and patients Caters for patients not yet on the HAART program, thus serves a wider user range Knowledge base is an integrated pool of various expert views therefore each answer supplied is about 85% System is a web based application, which is easily accessible from any computer or location with Internet access. 2.8 Conclusion The collected information above was used for the design and methodology of the proposed system. This chapter reviewed the domain in study i.e. HIV/AIDS, expert systems and a review of systems currently in existence. The following chapters of the document consist of the integration and modification of the gathered literature.

Free Essays on The “Birth“ (about Frankenstein)

The â€Å"Birth† In researching the life of Mary Shelley, I found that pregnancy and childbirth, as well as death, were a big part of her life. She had four children and a miscarriage that almost killed her. This was all before the age of twenty-five. Only one of her children survived to adulthood and outlived her. Her first child was born prematurely in February of 1815 and died in March. As any mother would be, she was devastated by this and took a long time to recover. Mary Shelley’s second child, William, was born January 24, 1816. That is when she thought of the story. Her first child had died and her second was only 6 months old. About six months later she was pregnant again. Pregnancy was at the front of Shelley's mind at that point in her life. This information gave me a new outlook on the story of Frankenstein. This may be a stretch, but I think that Frankenstein is partially about the fears of a pregnant woman. The story expresses many of the fears of a mother-to-be; What if my baby is deformed? Will I still love it like a normal child? Am I capable of being a good mother? Will I be okay through childbirth? I believe that Mary Shelley was expressing her fears related to the death of her first child, her ability to nurture, and the fact that her mother died having her. This is reflected in Victor’s failure as a parent. Victor Frankenstein labored on his creation for approximately nine months. Finally, he describes the â€Å"birth†: "I saw the dull yellow eye of the creature open; it breathed hard, and a convulsive motion agitated its limbs." (Pg. 51) Instead of reaching out to his child, Victor runs out of the room disgusted by the creature’s ugliness. When the creature follows after him, Victor continues to run away, completely abandoning his creation. While creating his â€Å"child†, Victor never considered whether it would even want to exist. He also did not think about the creature's appearance...

Free Essays on Their Eyes Were Watching God And Invisible Man Essay

Life has never been easy for African-Americans. Since this country's formation, the African-American culture has been scorned, disrespected and degraded. It wasn't until the middle of the 21st century that African-American culture began to be looked upon in a more tolerant light. This shift came about because of the many talented African-American writers, actors, speakers and activists who worked so hard to gain respect for themselves and their culture. Two writers were on the front lines of this movement, Zora Neale Hurston and Ralph Ellison. Their novels, Invisible Man and Their Eyes Were Watching God, probed deeply into the life and culture of the African-American, something that was practically unheard of. But not only did their novels shed light on the African culture, but they also shifted away from the traditional Romantic style of writing. Instead of focusing on religion or society, these novels focused on self-awareness, pride, and finding happiness. The merit of these novels pervades every page, but can especially be found in the themes, diction, and characterization. Both novels shared two similar themes: the pursuit of happiness and self-actualization. These themes had to be dealt with tenderly in an intolerant, white-culture society. Both Hurston and Ellison did this beautifully, in that their stories were not forceful nor preachy, but merely simple, candid tales of the lives of two ordinary African-Americans. Also, both authors refused to make their stories a fairy tale. At the end of each novel, neither Janie nor Invisible Man are as happy as they'd like to be. But, both novels focus not on the bittersweet end, but rather what the characters learned before they reached the end. Janie realized that her strength was in herself and her pride, with or without Tea Cake. And Invisible Man realized that "My problem was that I always tried to go in ...

Earth systems Essay Example | Topics and Well Written Essays - 1000 words

Earth systems - Essay Example posing a problem to the environment is the fact that the concentration of ozone in the ground-level is increasing while ozone in the stratospheric level is diminishing (Wright 774). This is a global environmental predicament because the stratospheric ozone has beneficial use while ground-level ozone produces detrimental effects. The stratospheric ozone layer was discovered sometime in the 1870s when scientists, led by G.M Dobson, observed the diminished amount of UV rays as they reach the earth’s surface, eventually attributing this phenomenon to ozone. By deduction, they concluded that the concentration of ozone in the upper atmosphere is higher than that nearer to the ground. A century later, it was discovered that certain elements could pose threat to this layer. When the US was planning to build supersonic transport planes (SST), studies revealed that the nitrogen oxide they would emit in the stratosphere layer, where they would be expected fly most of the time at a speed three times to that of sound and at an altitude of 12.4 miles, could destroy ozone (Konvicka 272). In the stratosphere, ozone is formed through a process called photolysis, when oxygen in the atmosphere is bombarded by solar UV radiation. This causes the two atoms of oxygen to split apart and merge with the atoms of other oxygen. The ozone gases then bond to form the ozone layer. This layer of ozone forms between 12 and 15 miles above the earth and protects it as well as life on it from dangerous UV solar radiation (Butz 376; Onursal et al 19). Ozone formation and destruction in the atmosphere occurs continuously and cyclically every time the UV rays of the sun act upon them, causing the breakdown of the gas and converting the resulting energy into heat. The heat raises the temperature at higher altitudes blocking the entry of the ultraviolet rays to the lower levels of the atmosphere. The split oxygen atoms then re-bond with the atoms of other oxygen to form new ozone. This continuous

Discussion Board Essay Example | Topics and Well Written Essays - 250 words - 4

Discussion Board - Essay Example A political process precedes any unanimous decisions. It explains why certain decisions have to be taken. This creates mutual understanding among members of a social forum. Successful decisions are discussed and agreed upon before ratification and implementation. The experience taught that concessions must be made while engaging in open deliberations. In future, a family engagement political process can achieve much if the members of the forum are open minded. My vision for future participation in the political process shall be to maximize on what all the members of the forum share in common. The future plan shall demand a strong follow up on the decisions and discussions of successful subsequent family engagement. In the first five years, my vision would be to establish a credible and consistent family engagement and discussion forum. In the next five years, I would build upon the gains of the deliberations from the previous forum. Political processes can be emotive be without a clear sense of purpose, they fail miserably (Constantino, 2008). Therefore, the visions would gradually build on consistent gains. Some of the anticipated gains would be sharing of resources, taking time bound targets and supporting the needy members of the
