The Use of DDT in Malaria Vector Control Article

The Use of DDT in Malaria Vector Control - Article Example As DDT is mainly used in indoors, it eventually generates the risks of deterioration of human health by a certain degree. This can be owing to the reason that direct exposure of this pesticide can damage the health of humans. Also, it can also be identified that there exist no such substitutes of DDT in order to prevent human health from severe diseases such as malaria. The other significant toxicology data which can be taken into concern in order to make the decision concerning the use of DDT in malaria vector control is that DDT is also responsible for causing various severe complexities. These complexities might comprise early pregnancy loss, fertility loss, pancreatic cancer, breast cancer, leukemia, diabetes, pyrethroids and neurodevelopmental deficits among others. By taking into concern the aforesaid toxicology data, it can be ascertained that DDT indeed imposes serious health hazards to the humans which is a major cause of concern. It can be viewed in this regard that due to the seriousness of this issue, countries such as the United States is strongly working upon to develop appropriate alternative pesticide in order to reduce the health hazards and provide health-related benefits to the humans. But relating to the case of Africa which has a record of occurring the disease i.e. malaria, World Health Organization has allowed indoor use of DDT. But the main dilemma concerning this factor is that DDT also acts as a strong deterrent to fight against malaria as well as vector control... It can be viewed in this regard that due to the seriousness of this issue, countries such as the United States is strongly working upon to develop appropriate alternative pesticide in order to reduce the health hazards and provide health related benefits to the humans. But relating to the case of Africa which has a record of occurring the disease i.e. malaria, World Health Organization (WHO) has allowed indoor use of DDT. But the main dilemma concerning this factor is that DDT also acts as a strong deterrent to fight against malaria as well as vector control and at the same time, it poses serious chronic health hazards to the humans (Agency for Toxic Substances and Disease Registry, â€Å"DDT, DDE, AND DDD†). However, a decision of creating an alternative pesticide is needed to be taken which may help in resolving this particular issue by a certain degree (Berg, â€Å"Global Status of DDT and Its Alternatives for Use in Vector Control to Prevent Disease†). 2. USE THE FO UR PHASES OF THE DISPOSITION OF A TOXIC COMPOUND TO ASSESS THE TOXICITY OF DDT The four phases have been described hereunder. Absorption-DDT mainly gets absorbed in the human body when the pesticide is exposed to the skin and lung. Ingestion also happens due to DDT which enters into the human body causing deterioration in the health of human beings at large. Distribution-If DDT is able to enter the human body, then it is circulated/distributed to the entire body parts in a fast way. It also contains high amount of fat which quickly spreads into the body imposing adverse effect upon human’s health. Metabolism-The metabolism phase or process of DDT primarily include certain effective processes that encompass dechlorination, dehydrochlorination, oxidation,

Focusing on the first scene Essay Example for Free

Focusing on the first scene Essay At the beginning of the play, from Alfieris monologue you can tell that there is constant tension between the people in the neighbourhood because of when he says how I often think that behind that suspicious little nod of theirs lie three thousand years of distrust. This shows that this trust hasnt been broken recently, it has been going back generations upon generations. The comment Oh, there were many here who were justly shot by unjust men. Justice is very important here says to the reader that no matter how much violence it may lead to it will be done, and in the hands of the Italian civilians. They dont go to the police and instead fight it out themselves. Things are obviously starting to calm down now though because Alfieri no longer keeps a pistol in his filing cabinet and says that people are now quite civilized, quite American. When we first meet the Carbone family, we see an excited Catherine welcoming Eddie home from a long day of working in the docks. Catherine obviously has been waiting around for his approval of her new dress because she is very excited when she asks him what he thinks, (running her hands over her skirt) I just got it. You like it? and when he also asks about her hair change she wants his immediate approval. Eddie delivers with flattering comments like oh, your mother was alive to see you now and you look like one of them girls that went to college which is a complement in itself because it is saying she looks smart and sophisticated and not like any average person. Eddies comment about how the dress looks a bit short when she sits down and how she walks is what reveals his protectiveness over her and how she may look attractive to other men. Listen, you been giving me the willies the way you walk down the street Im telling you youre walking wavy He doesnt like that she may seem attractive to other guys in the neighbourhood. This upsets Catherine because Eddies approval obviously must mean so much to her. She even almost breaks into tears because he disapproves of how she walks. Eddie has always treated Catherine like a baby, even now when shes 17 years old he says Youre a baby, you dont understand these things. when he talks about her waving to Louis he warns her that I could tell you things about Louis which you wouldnt wave to him no more. Louis is obviously not the nice guy that Catherine thinks he his and seems like he has a dark past. From Catherines comment about how I wish there was one guy you couldnt tell me about means that Eddies has a dark story about every guy in the neighbourhood which is so bad it would actually lead to an end of conversation between them and Catherine. Beatrice and Eddies relationship has an obvious problem which is that he has more feelings for Catherine than he does for Beatrice. Which Beatrice realises but Eddie doesnt. At the beginning Beatrice isnt so open about the fact that she knows Eddies has feelings for his niece, but after some time she starts to argue with Eddie whenever its just them left in the room. But right now at the beginning Beatrice doesnt speak it out. When Eddie tells Catherine that Beatrices cousins have landed, B. is very concerned about how the house looks and that she hasnt bought a new table cloth (astounded and afraid) Im I just I cant believe it! I didnt even buy a new tablecloth; I was gonna wash the walls. Eddie is actually a nice and caring person and not just the guy who brings in the money. He reassures Beatrice that Listen, theyll think its a millionaires house compared to the way they live this calms her down a bit but she is still a little doubtful until Eddie says Youre saving their lives, whatre you worrying about the table cloth? They probably didnt see a tablecloth in their whole life where they come from which begins to calm her down. When Beatrice and Catherine reveal to Eddie that Catherine may start working, it isnt surprising that Eddie is worried because he has feelings for her and obviously doesnt want her to go to work and meet other men. Also Eddie obviously usually has say in the house because as soon as they say Catherine has a job he replies with what job? Shes gonna finish school. When Catherine tries to change his mind he interrupts her and says No no, you gonna finish school. It seems everything has to go through eddies approval before anybody can make any changes to anything. But when the two women manage to get him to half agree he still isnt sure about it. The stage direction showing that hes strangely nervous proves this. It seems like there is no end to his questions because it goes from wheres the job? What company? to Nostrand Avenue and where? to what about all the stuff you wouldnt learn this year though. Eddie is just trying to keep Catherine at school so she will still be living in the house. If she makes her own money sooner or later she will move away. If she has been offered a job and been told she is the best student in the class there is no more for her to learn. Then it turns to That aint what I wanted, though. Which shows that Eddie had a plan set out for Catherine this whole time which would probably keep her in the house for as long as possible and now she wont be following it. He still tries to convince her that she shouldnt go to work by saying Near the Navy Yard plenty can happen in a block and a half. And a plumbing company! Thats one step over the water front. Theyre practically longshoremen. Eddie himself is a longshoreman so this obviously means if she is going to leave he wants her to leave to better people than himself or Louis or the plumbers at her stenography job. Beatrice replies with Yeah, but shell be in the office, Eddie but again its not what Eddie had in mind. He had had good intentions for Catherine because he wanted her to be with different kind of people. I want you to be in a nice office. Maybe a lawyers office in New York in one of them nice buildings. He obviously doesnt want her to go because when Beatrice tells him to think about it (he is silent, staring down at the tablecloth, fingering the pattern). Beatrice tells him that shell get out of the subway and be in the office in two minutes but Eddie is somehow sickened by the idea of her working in that neighbourhood. After some time Eddie actually agrees to let her work, Catherine is excited and says that she will buy new dishes with her first pay and Eddie replies with a sudden and then youll move away Catherine denies this accusation but Eddie still carries on with Why not? Thats life. And youll come visit on Sundays, then once a month, then Christmas and New Years, finally Catherine again denies the accusation but Eddie is hurt that she will be leaving him and the house and this shows he isnt ready to move on yet.

Graduation Speech :: Graduation Speech, Commencement Address

Well, seniors, here we are. It is time for us to "take on the world" as the popular Christian song states. Not only are we going to be responsible for taking on the world in the near future, but we will also be responsible for many, many other things. Just what we need, right? Well, think about it. New college classes, new jobs, new friends, possibly new spouses in the slightly distant future, new rug-rats in the more distant future. I don't know about you, but the idea of the world giving that much responsibility to someone like -- you fill in the blank -- scares me severely. Are we going to make it? If so, how? To help answer these questions, we needn't look any further than one of the greatest of our new obligations: the encouragement of one another. Now before you write me off as a lunatic or a "softy" (or both), think on the word I just used. Encouragement. Webster says that to encourage is "to inspire with courage, spirit, or hope;" but these are just mere words, right? How can a dictionary express the meaning of something that can change a person's life in a moment or lift someone from the abyss of despair to that wonderful feeling of being loved and needed? I can tell you truthfully that without the daily encouragement that I get from those around me, I would not be standing before you this evening. These people include my parents, my friends, my teachers, anyone who is able to say a nice world to me to inspire me to do my best and keep going. All of you must have experienced some form of encouragement in your lives or else you wouldn't be joining me on this football field to celebrate our completion of high school. My point is this: Encouragement is one of the most powerful forces that can be unleashed on this planet. Here's a little list of things that can be accomplished without encouragement ... Fairly short list, isn't it? I do not have a list of the things that are possible with encouragement because the use of that much paper would be environmentally devastating. You get the picture. We need encouragement and we need it as often as possible. Just like the air we breathe, if we lack encouragement in our lives we often feel suffocated. Are you getting enough of it in your life, or are you suffocating?

Social Issues in Colonial Africa

The title of a book may give the reader an idea of the story or it may make more sense after reading the book. The title Heart of Darkness by Joseph Conrad prepares the reader for something unpleasant.The title Things Fall Apart by Chinua Achebe also gives the reader a hint of bad things to come. After reading both it is clear to the reader the titles refer to the terrible social issues caused by the appearance of European colonizers in Africa.The â€Å"darkness† is not just the absence of light typical in an African jungle. It is the mental and emotional dark side of the colonizers, and the dark result of their intrusion on African societies. There are many â€Å"things† that â€Å"fall apart† in Africa when the Europeans arrive. There is an immediate breakdown in communication between the two cultures. Then the domination and brutality of the Europeans causes the African society to â€Å"fall apart†.Both books show the terrible result to the Africans at the hands of the Europeans. Both authors are very effective in bringing the reader â€Å"into† the story. However, each author uses different methods and styles to illustrate the social attitudes, issues and impact arising from colonization.Joseph Conrad uses a narrator, Charlie Marlow, to tell the story of Heart of Darkness. Marlow is a sailor who tells his shipmates the story of how he had worked for a European trading company in Africa.He was employed to take a boat up-river from a company headquarters to bring back Mr. Kurtz, their best ivory trader. Marlow soon witnesses the European attitude and treatment of the Africans. He describes the horrible scene of the Europeans’ slave laborers: â€Å"They were dying slowly—it was very clear.They were not enemies, they were not criminals, they were nothing earthly now—nothing but black shadows of disease and starvation, lying confusedly in the greenish gloom† (Conrad 64). One of the men who worked at the station was a clerk who tells Marlow â€Å"When one has got to make correct entries, one comes to hate those savages—hate them to the death† (Conrad 66).Marlow learns that the behavior of the Europeans at their headquarters is just the beginning. Although Kurtz is the company’s best ivory trader, he is described as much more to Marlow: â€Å"He is a prodigy†¦an emissary of pity, of science, and progress, and devil knows what else† (Conrad 75). Marlow can begin to see the dark side of the company as the clerk relates Marlow is â€Å"of the new gang—the gang of virtue.The same people who sent him specially also recommended you† (Conrad 75). Marlow discovers a report Kurtz had written for the company describing his experience in the jungle with the Africans. Marlow states that in light of all that happened, and would happen, the beginning of the document â€Å"strikes me now as ominous.He began with the argument that we whites, from t he point of development we had arrived at†¦ ‘approach them with the might of a deity’† (Conrad 111).  It is obvious that Kurtz realized that with all of the â€Å"modern† European goods and weapons he would appear to the Africans as some sort of superior being. What would be even more ominous was Kurtz’ â€Å"note at the foot of the last page†: ‘Exterminate all the brutes!’† (Conrad 111).

Guyana Defence Force in National Development

THE GUYANA DEFENCE FORCE IN NATIONAL DEVELOPMENT: CIVILIAN-MILITARY RELATIONS – SOME PERSPECTIVES The case for the Guyana Defence Force to be involved in national development is enshrine in the birth of the Force and it is articulated as the third part of the Force’s tripartite role: 1. â€Å"Defend the  territorial integrity  of Guyana. 2. Assist the civil power in the maintenance of law and order when required to do so. 3. Contribute to the economic development of Guyana. †[1] The question then has to be, how will the Force be most effective in fulfilling this role. This essay contends that good civil-military relations with government and non-government organisations are critical to the successful fulfilment of this role. To demonstrate the relationship between successful national development activities and good civil-military relations, I will examine areas of development the Force can be most effective and show that the level of effectiveness will be driven by the quality civil-military relations in the said area. What then are the areas of development that the Guyana Defence Force can be most effective? The following areas of development were selected because the military role and level of success is easily measureable: 1. Engineering – infrastructural work; road construction, housing projects for low income earners, etc. 2. Health services – medical outreaches; military doctors, dentists providing service in hinterland areas, etc. 3. Education – military personnel both soldiers and civilians are employed as teachers in hinterland areas where there are limited schools, etc. 4. Economic – military personnel being employed on economic projects; such as the establishment of micro-industries, for example, farming. . Administrative – Officers are seconded to administrative positions in government agencies and even the other Services of the Joint Services. 6. Aviation – Augmenting the transportation of people and goods to the hinterland regions. Throughout most of its history the Force has been involved in national development by way of executing engineering projects particularly in the areas of hinterland roads and bridges construction. Also, the construction of low cost housing and airstrip rehabilitation are other areas where the Force participated in engineering works. This commitment to national development by way of executing engineering projects was highlighted in â€Å"Guyana’s Draft Second Development Plan, 1972-1976 which assigned specific responsibilities, to the Engineer Corps, for the construction of hinterland roads and bridges, the upgrading of airstrips and projects such as the rehabilitation of the hydro-electric power station at Tumatumari†[2] The success of the Force involvement in these ventures is commendable, however, the Force was unable to remain committed to such ventures as a single source agency as time progress. This was due to lack of resources; both human and mainly material. Therefore, one can argue that a civil-military relation framework by way of partnership with a government or non-government would have enhanced the Force’s longevity in its commitment to such ventures. This was not lost to the Force administration and is exemplified in the Force’s most recent commitment to engineering projects as detailed in the Stabroek News. â€Å"Five ranks of the Guyana Defence Force (GDF) received keys to new homes at Tuschen Housing Scheme, East Bank Essequibo last week as part of a an ongoing partnership between Habitat for Humanity Guyana; the Ministry of Housing and the army to assist ranks with affordable housing. [3] Noteworthy is the commitment of government or non-government organisations to have such partnerships with the Force in this sector, as detailed in the same article, â€Å"Chairman of the Management Board at Habit for Humanity, Alex Graham remarked that the GDF has the capacity to play an integral role in various aspects of the housing response while pointing out that the army can also help in the building of homes for persons outside the GDF family. †[4] This demonstrates that there is clear recognition by non-government agencies that good civil-military relations are beneficial to both parties. Further the Force will not be required to singlehandedly seek out and forge these partnership. The Force has a rich history of providing medical services to rural and hinterland villages as part of its medical outreaches. The Force has been impressive in its support to national development in this sector by providing free medical and dental care to thousands of Guyanese. This is not surprising since common to most underdeveloped countries is the lack of capacity to provide quality medical services as you move away from the cities and main towns. This is the case in Guyana and its exasperated by our demographics, terrain in hinterland areas and the lack of adequate transportation facilities to hinterland and rural areas. The support by the Force in this sector has continued throughout its existence and remains source of kudos as highlighted in the following excerpt from Stabroek News. â€Å"Close to 200 Upper Berbice River residents benefited from dental and general medical care when a team from the Guyana Defence Force (GDF) Medical Corps hosted an outreach exercise there recently. According to the army, residents said they were grateful for the exercise and expressed the desire for a doctor to visit at least once per year. †[5] The quality and level of success gained in this sector can be improved with better civil-military relations with government and non-government organisation. Similar sentiments in regards to the value of these relations were expressed by the Chief of Staff in his 2011 Command Directive. â€Å"In 2011, I plan to establish statecraft partnerships with the Ministries of Education and Health. †[6] The use of military personnel to augment the efforts of the Ministry of Education to provide education at any level and in any area of the country has not been a feature of the Force for any substantive period. Notwithstanding this, one can argue that the efforts by the Force to educate its ranks directly impacts on national development. Since when members of the Force return to civilian life their level of technical and vocational education will have a direct impact on how they are integrated to the countries labour force. Therefore the Force commitment to educating its ranks underscores its efforts to national development in this sector. However, the efforts of the Force to educate its ranks have had its own challenges. The main challenge was the ability of the Force to establish a system that linked educational development with the evolution of soldier’s careers. â€Å"As part of their promotion standards, soldiers are required to attain specified levels of academic education but these standards had to be waived since no formal means existed for upgrading soldiers’ education. † [7] The importance of good civil-military relations to enhance the Force performance in this sector has been underscored by the recent efforts by the Force in launching of its Academic Education Programme. 8] This coupled with the Career Development Plan[9] and the advent of â€Å"promotion examinations for promotion up to the rank of major†[10], underscores a recognition by the Force that civilian input and to an extent civilian oversight is critical to success in this sector. Also, the aforementioned planned stat ecraft partnership with the Ministry of Education and the fact that Force Education Department is staffed primarily by civilian teachers, establishes the importance of good civil-military relation for the strengthening of the Force’s capacity in this sector. The Force direct involvement in economic activity in support of national development is demonstrated with its involvement in agriculture. The Force Agriculture Corps has the mandate to produce mainly poultry, pork and eggs to augment the Force’s ration requirements. Throughout its history from since the establishment of Agriculture Corps the Force had measured success in this sector. This success is termed measured since in Guyana’s Draft Second Development Plan, 1972-1976, the Force â€Å"was tasked with the development of farms at Onverwagt in Berbice, Butenabu in Mahaicony, Vergenoegen in the Essequibo, and at Garden of Eden in Dememerara. [11] However, presently the Force only has one farm at Garden of Eden in Dememerara. Hence, after existing in excess of three decades the Force Agriculture Corps has not achieved the capacity to provide the Force with its ration requirements of meat, eggs and vegetables. The lack of fulfilment of its potential in this sector can b e attributed to the lack resources; both human and material. The Force performance in this sector can improve via partnerships with government and non-government organisations. The establishment of such civil-military relations will impact positively on the Force performance in this sector. To this end the Force continues to pursue such partnership as demonstrated with the Force involvement in â€Å"the national pig-breeding programme, a joint effort between the Ministry of Agriculture and the Guyana Defence Force†[12]. The Force at various period of its existence seconded mainly officers and in a few cases other ranks to government and non-government organisation. Officers were primarily seconded to administrative positions in government agencies and even the other Services of the Joint Services. This practice helped in National Development by making managerial and administrative skills readily available to beneficiary government agency. The Force involvement in this sector illustrates the value of good civil-military relations both to the Force and the Nation. This is underscore by the fact that military officers have attained high ranking appointments, namely permanent secretary and currently Accountant General at the Ministry of Finance. The Force since its early days of existence played a pivotal in aviation in Guyana. The Force helped in the pioneering efforts in aviation in Guyana. Aviation is arguably the first area where the value of good civil-military relations and the capacity of the Force to positively impact on National Development were demonstrated. [13] However, as the civilian capacity developed in this sector the Force was seen has having a negative impact in the commercial viability of this sector. I am of the view that the deterioration of civil-military relations in this sector helped in fostering this perception of the Force. There remain numerous areas in this sector where the Force, the private sector, and government and non-government organisations can benefit from good relations. No one entity can satisfy the commercial, security and safety requirements for aviation support in Guyana. The wide expanse of hinterland settlements, the limited aircraft and technically trained personnel suggests that there is room for all stake holders to make a positive impact in this sector. The Guyana Defence Force recognises and accepts it has a role to play in National Development. This is exemplified in the many initiatives and projects the Force has been involved throughout its existence primarily in Engineering, Health Services, Education, Economic, Administrative and Aviation Sectors. The question of how the Force will be most effective in fulfilling its role of contributing to National Development has been answered. The Force must embrace partnership with government and non-government agencies in those sectors where we are poised to make an impact on National Development. This pursuit and ultimate realisation of good civil-military relations will enhance the Force capacity to contribute to national development activities. REFERENCES Best G. A. R.

If you want SAT score information for other schools not listed above, simply search for "[School Name] PrepScholar admissions" on Google. The list above won't mean much without a Rosetta Stone of SAT scores. How Do You Interpret These SAT Rankings? Hopefully, you nowhave an idea of the highest expectations schools can have for students' SAT scores. This information isn't that helpful, though, if you don't know how students tend to perform on the exam. The SAT iscurrently scored out of 1600 points: 800 points possible for the Math section, and 800 points possible for the EBRW section. Currently, the average composite SAT score is 1060. In general, a student is considered to have an excellent SAT score if she is in the top 25% of test takers. To fall within this category, you'd needa composite score of around 1200or higher. On the other hand, a student is considered to have a low SAT score if he is in the bottom 25% of test takers, with a composite score around 910 or lower. Read our guide to learn more about how to think about "good" or "bad" SAT scores. Are These Really the Top Schools? The average SAT scores listed for the schools above are much higher than the overall average - in fact, some of them are pretty close to perfect. Butif a school has dizzyingly high average SAT scores, does this mean it's necessarily a top school? In a sense, yes. Schools that attract the strongest applicants tend to do so because they have excellent reputations and offer strong undergraduate programs. When schools have a stronger student body - undergraduateswith very high SAT scores, for example - they tend to build up a positive reputation and get more competitive as a result. It's a positive feedback loop: strong students with strong SAT scores continue to attract strong students with strong SAT scores. Many of the schools on the list above are ranked on well-known "best colleges and universities" lists, like the one that US News World Report publishes each year. These ranking systems aren't perfect, but they do take many quantifiable factors into account (besides just standardized test scores) when evaluating US schools. You’ll notice, for example, that all of the Ivy League schools are on this list.These schools have such high average SAT scores because they are well-reputed enough to attract students with exceptionalscores. A small side note: you might have noticed a trend in the scores that made you pause. Several of the schools listed tend to have higher Math averages than EBRW averages. Quite a few of these schools are heavy in STEM fields (science, technology, engineering, math);these sorts of schools may weight test scores more heavily in the application process than your average liberal arts institution, which could account in part for their high test averages. With thatsaid,it’s important to note that the best school you can attend isthe school that’s the best fit for you. Perhaps you’re interested in schools with strong Romance-language departments, core curriculums, or generous financial aid programs. The reality is, not all of the schools listed above will meet every student’s criteria. What’s most important to your success in college and beyond is that you find an institution that is able to support and foster your interests, passions, and future career path. You wouldn’t list a school renowned for its engineering program as your top choice, for instance, if you wanted to major in comparative literature! Are These Schools Really the Most Competitive? The way you gauge a school's competitivenessis by looking at its acceptance rate.The greater theratio of student applicants to spots in a new freshman class, the lower a school's acceptance rate will be. Schoolsare defined as competitive if many students are vying for a limited number of spots. In terms of acceptance rates, many of the schools above are some of the most competitive in the country. Several have acceptance rates of less than 10%.There are some equally competitive niche institutionsnot included on the list, such as Cooper Union, the US Naval Academy, the US Military Academy, and Alice Lloyd College - all of which have extremely low acceptance rates. In sum, the top schools ranked by SAT scores do tend to be competitive, but they're not the only institutions with very low acceptance rates. Just because you're lagging behind the group doesn't mean you won't have an opportunity to catch up. What If Your SAT Scores Fall Below the Listed Averages? Do You Still Have a Chance of Getting In? So what do you do if you're trying to get into a very competitive school, but your scores don't measure up? In order to be a competitive applicant,you’ll have to make up for that perceived weakness elsewhere in your application. You can do this, for example, by earning an exceptionally high GPA or making an impressive commitment to community service. Admissions officers consider students' applications holistically - meaning that they don't just focus on standardized test scores. The extent to which you have to "make up" for a low test score with other parts of your application depends on how far you fall below the school's average. At an elite school, it's unlikely you'll get in with very low SAT scores, even if the rest of your application is strong. So how do you know whether your scores fall below a dangerous threshold? Because the scores above are averages, you know that about half of all accepted students will have SAT scores lower than the ones listed. You can also access information on the â€Å"middle 50† for each school - i.e., the scores at the 25th and 75th percentiles for admitted students. This will tell you the range of scores that the middle 50% of accepted students have. You’re generally a safer applicant if you fall in this middle 50% than if you’re in the bottom 25% of students. Another factor to consider is that each school will weigh applicants’ SAT scores a bit differently in the application process. Schools like Washington University in St. Louis, for example, are well known for heavily favoring students with excellent scores. Some other schools may forgive below-average test scores if another part of your application impresses the admissions committee (refer to my examples above). There are even schools that don't require test scores at all! If you want to calculate your chances of getting into a particular school, use our admissions pages. You can find these by Googling "[School Name] PrepScholar admissions." These pages will give you more information about the school you're interested in. Finally, if it turns out that your SAT scores just aren't up to par,consider taking the ACT. All four-year US colleges and universities accept ACT scores, and some students strongly feel that they perform better on the ACT than on the SAT. What's Next? If you're considering adding some of these schools to your college application list, you'll want your SAT scores to be the best they can be.

Paronyms and Paranyms

Paronyms and Paranyms Paronyms and Paranyms Paronyms and Paranyms By Maeve Maddox Thanks to a question from an ESL learner, I discovered the word paronym. Paronym The OED offers three definitions of paronym in the context of word types: 1. A word which is derived from another word or from a word with the same root, and having a related or similar meaning, (e.g. childhood and childish); a derivative or cognate word. 2. A word from one language which translates into another with only minor changes in form, or with no change at all; a word formed by adaptation of a foreign word. 3. A word similar in sound or appearance to another; especially, a near homonym. The ESL student was looking for a list of words like these: affect/effect farther/further alternately/alternatively interested/interesting corrupted/corrupt adopt/adapt continuous/contiguous I usually call such words â€Å"words commonly confused† or- in headline-speak- â€Å"Confused Words.† Like other nouns that denote semantic terms, paronym is made up of a Greek element, par- (â€Å"altered†), plus the suffix -onym (â€Å"name† or â€Å"word†). Note: The word-forming element par- can also be rendered alongside, beyond; contrary; irregular, and abnormal. The earliest citation for paronym in the sense of â€Å"a near homonym† is 1867. The other uses also emerge in the second half of the 19th century. In the course of researching the meaning of paronym, I discovered that it has a paronym of its own: paranym. Paranym Lance Hogben (a zoologist who wrote popular books on language) used the word paranym in 1963 in sense of â€Å"a near synonym,† but the OED notes that this use is â€Å"rare† and fails to cite any other examples. A different, more useful definition is this one: paranym: A euphemistic word or phrase whose literal sense is contrary to the reality of what it refers to, used especially to disguise or misrepresent the truth about something. Here’s the earliest OED citation for this use: A newspaper columnist has recently been collecting what he calls ‘paranyms’- words whose meaning is generally the opposite of that intended by the speakerThe writer Brian Aldiss thereupon contributed an example he had found in the New Testament: ‘â€Å"everlasting life†; in other words â€Å"death†Ã¢â‚¬â„¢. The Listener, 1976. Whereas I find words like synonym, antonym, homonym and heteronym extremely useful because they are easily defined and well known, I won’t be using paronym because it has more than one meaning. Paranym, on the other hand, appeals to me. In these times of political correctness, we can use a word that means â€Å"A euphemistic word or phrase whose literal sense is contrary to the reality of what it refers to.† It’s a worthy companion to Stephen Colbert’s truthiness: Act or quality of preferring concepts or facts one wishes to be true, rather than those known to be true.

Heart of Darkness Essay Example | Topics and Well Written Essays - 1000 words

Heart of Darkness - Essay Example In making his comments upon London at the beginning of the book, Marlow illustrates the lesson he learned in the jungle, that the social impression of imperialism as an illuminating force for good brought to the desperate primitive peoples was a lie based on false cultural beliefs. He does this by reflecting out loud about the history of London and how it parallels in many ways the current history of Africa by questioning the difference between civilized and savage. It is obvious to the other men sitting on the deck that the concept of light as it is applied to men refers to the 'enlightened' or advanced culture. The narrator makes this clear as he talks about the rich history of the Thames and the glorious characters of those who have traveled on it. "They had all gone out on that stream, bearing the sword, and often the torch, messengers of the might within the land, bearers of a spark from the sacred fire. What greatness had not floated on the ebb of that river into the mystery of an unknown earth! ... The dreams of men, the seed of commonwealth, the germs of empires" (Conrad, 3). These are all presented as positive elements or a kindness bestowed on those less fortunate. The splendor that was England would be graciously shared with the lazy, unintelligent brutes of the dark places without any consideration as to where that wealth was coming from. It is clear from the way the narrator describes things that he considers England to have always enjoyed such a privileged and recognized status. Only one of these men, Marlow, seems to see things differently, describing London in terms that make it sound very much like their present conceptions of the darkness or uncivilized nature of Africa. It is just as the narrator is winding down about the greatness of the civilization that lives on the banks of this river that Marlow interrupts everyone's thoughts with the sudden and cryptic statement used as epigraph above: "And this also ... has been one of the dark places of the earth" (2). In this passage, Marlow talks about the area of London as it was when the Roman soldiers found it. Although there was already a flourishing society at work on the island, as there were several flourishing societies found in Africa as European explorers pushed deeper and deeper into the forests, the Romans felt themselves engulfed by the same kind of darkness being experienced in Africa. â€Å"Sand-banks, marshes, forests, savages – precious little to eat fit for a civilized man, nothing but Thames water to drink. †¦ Here and there a military camp lost in a wilderness, like a needle in a bundle of hay – cold, fog, tempests, disease, exile, and death – death skulking in the air, in the water, in the bush. They must have been dying like flies here† (Conrad, 4). The darkness he describes for the Romans entails much more than the simple change in geography and weather from their Mediterranean home and sounds very much like how the Europ eans thought of the men they found in Africa at that time - savages who have nothing decent to eat or drink, strange illnesses, difficult or impossible terrains. Marlow's reflection on the Romans also draws parallels between the ancient Romans and the contemporary British as bringers of light to the dark places

What is Epistemology Essay Example | Topics and Well Written Essays - 2000 words

What is Epistemology - Essay Example The link of epistemology into ontology and the way epistemology shape social research in general. According to scientists, there is a significant difference between too expressions: â€Å"I know that† and â€Å"I know how†. For instance, it is well-known that 1+1=2, however, here we could think not only about the result, but about the process itself: how there two numbers should be summed up. When we state that we â€Å"know† something, the question arises why we â€Å"believe† that. When we â€Å"believe’ in something we usually think that this â€Å"something† will not make us disappointed, for example we may believe in our national basketball team and its victory. However, epistemology considers â€Å"belief† from another point of view. For example, when we believe that the grass is green that means that we consider the statement that the grass is green to be correct. Every statement is simply a preposition of someone else and it does not mean that everybody must believe it .At the same time, if something represents a real fac t, it is true. The main controversy in this area is concentrated on study of the nature of knowledge and its connection to related concepts: information, conviction, and rationalization. It is connected with the method of knowledge acquisition and uncertainty about various statements. The different arguments of rationalism and empiricism and the controversy that occurs on the base on this difference is connected to different experience of the people in their attempts to obtain knowledge. According to rationalists, there are significant methods to obtain information autonomously of experience at the same time as empiricists consider experience to be very essential in knowledge acquisition (Fodor 1975). The vision of rationalists is usually built in the following way: they state that sometimes our knowledge obtained through intuition is more reliable, than that obtained from experience. Then,

U.S. History Civil War-Present - Assignment Example On the other hand, social conservatism were those who were staunch supporters of social values. The two types of conservatives have worked towards building the political position of America up o where it is as of now. Different leaders supported conservatism in their own ways. For instance, President J. F. Kennedy, illuminated conservatism by advocating that all rights of the people are protected. During the 80’s president Ronald Regan favored the conservative side by reducing taxes, deregulation, increasing the US military budget, just to mention but a few (Berkin, 1865). This era was dubbed as the ‘’Regan era’’. Initially, conservatism was only associated with the Republican Party. However, things started changing in the 50’s where southerners became conservatives due to segregation. This triggered a coalition that helped to foster domestic legislation. The union of the two conservatives came up with ideologies that were not well received by the Soviet Union. In the end, the Soviet Union could no longer trust the United States hence the beginning of a historical rivalry (Berkin, 1865). The Soviet Union was so engrossed in its bid to expand communism that it started creating alliances with different nations against America. In the end, America is seen as a country whose cultural structure influences how politics are run. And this works best for America as a nation. In as much as the Soviet Union was not impressed by this move, the American culture stood the test of time of the soviet’s opposition. The 1980s American history shaped the nature of difference in cultural and social standings in the state. Reagan’s administration applied various responsive measures to balance these differences. A later influx of other cultures such as Latinos and Asians made these efforts more difficult. In the 1980s the United States embarked on a worldwide mission to spread its democratic ideals. It is the systems and institutions set up during this time that

Introduction There have been on-going debates on the health and safety issues in different organisations and industries, more specifically, in the construction industry. According to Rowlinson and Lingard (2005), it is important to acknowledge that construction industry is facing many ch allenges in the globalisation era because of the health and safety issues. Generally, it is believed that organisational philosophy is one of the issues, which influence the performance of the building industry. The organisational culture is the set of shared values and beliefs that people of organisation follow, and is reflected by their behaviour, attitude, and reaction with each other and with organisation’s stakeholders. ... The study also seeks to explore the impact of culture and safety, on project performance. The study remains based on the building industry located in the Kingdom of Saudi Arabia. The current health and safety policies being adopted by construction industry in Saudi Arabia, the accidental rates in construction sites, and the factors that influence implementation of safety culture in construction companies will also be examined. The research would be helpful in determining the degree to which culture influences safety and performance of the project. 2. Background Organisational culture is simply the collective shared values, attitudes, and behaviours of people working in the organisation. It reflects by every action of an organisation: how an organisation takes decision, treats its employees, and conducts its business. Additionally, it considers various aspects of employee such as how they behave with stakeholders of the company. Organisational cultures influence every part of the busi ness including organisation’s environment, its product and services, safety and health of the environment (Coffey, 2010). The construction industry of Saudi Arabia is one of the largest and fast growing markets; it was valued at $36.5 billion in 2011, and is expected to reach $43.8 billion by 2013 (Zawya, 2012). Therefore, to ensure that the targeted growth in the construction industry is realized, an understanding of the influence of culture on safety and project performance is essential. According to the U.S.-Saudi Arabian Business Council, the construction industry in Saudi Arabia has potential growth in future. More demands in residential and commercial construction

BL21 (DE3) RIL competent cells to express tau protein Article

BL21 (DE3) RIL competent cells to express tau protein - Article Example The BL21-CodonPlus(DE3)-RP cells possess excess of the argU which code identifies the arginine codons AGA, tRNAs which encodes the proline codon CCC and proL genes which code tRNAs which identifies the arginine codons AGG. The BL21-CodonPlus (DE3)-RIPL cells contain extra copies of the argU, ileY, and leuW as well as the positive tRNA genes (Sussman, & Israel 218). This particular strain liberates the appearance of heterologous proteins obtainable from organisms that possess each AT- or GC containing genomes (Sussman, & Israel 220). BL21 (DE3) RIL is important in the expression of the tau protein since it promotes the optimal protein transformation. The Tau proteins are steadies microtubules, they are copious in nerves in the CNS and are least frequent somewhere else (Robbins & Maria 230). BL21 (DE3) RIL is important in the assembly of tubulin assisting in the optimal transformation of cells that induce the expression of tau protein. Tau possesses two N-terminal exons and has all the microtubule attaching repeats in the largest human tau isoform. This promotes the transformation and the expression of the tau protein in the medium (Robbins & Maria

Microsoft Baseline Security Analyzer - Essay Example So my plans are to find out what error is preventing my firewall form being able to be scanned. I will also take protective measures in establishing password expirations for my user accounts. Overall, I’m not surprised at the results of my security assessment due to the fact that I’m the only user of this computer, and I exercise safe practices while using it, and I only use it on an as needed basis. MBSA is multi-threaded and has the capacity to scan a whole domain and extensive address range within a short time frame. One MBSA system can operate a scanning process in a few seconds to several minutes; however, this depends on the number of user machines. A lot of time is usually taken in scanning for weak passwords when utilizing MBSA machines. Such tests involve checking empty passwords together with common password dimensions such as: The name of the machine, user name, and administrator. In order to avoid frequent checking of passwords, it is pertinent to scan a person’s premises more often. When the weak passwords are not tested or checked, the option for testing (Checking) passwords for Windows accounts as well as SQL accounts are disabled (Fahland and Schultze, 2010). Majority of users log on to computers or in to remote computers through utilization of a combined user name and a password keyed into the keyboard. In spite the fact that there exist various alternative technologies meant for authentication ranging from; smartcards, biometrics as well as instant passwords, a good number of organizations to some extent continue to rely on traditional passwords; this is projected to continue for sometime. It is therefore imperative that organizations formulate and implement password policies to guide the use of their computers such as the use stronger passwords. Such passwords possess the required level of complexity characterized by the character facets and the length dimensions. This feature makes it hard to hard such passwords.

Things Fall Apart Essay Example for Free

Things Fall Apart Essay Chinua Achebe’s novel â€Å"Things Fall Apart† tells the story of Okonkwo, an ambitious man from the Igbo village of Umuofia, in modern day Nigeria at the onset of the Colonial era. Okonkwo is a rising member of the society until he inadvertently kills a kinsman and must flee for seven years to his mother’s clan so as not to offend the earth goddess of the village. During this time, British Colonialism reaches the Igbo people and quickly alters their traditional way of life. Through this tale of the Igbo Achebe seeks to illustrate the complexities of African societies and how deeply these African societies were affected by Colonialism. Many Europeans entering Africa during the colonial period viewed African society as â€Å"primitive† and lacking the depth of western society. Achebe’s novel seeks to illustrate that far from being unstructured and chaotic, African society was very complex. Umuofian society was not parceled into different spheres of practice but instead maintained a delicate balance in which all aspects of society, from religion to gender roles, are intertwined in order to keep the society running smoothly. The village was lead by elders or men â€Å"of title† who earned their status mostly through personal achievements rather than inheritance (Achebe, 7). Achievements, wisdom, and age all merited respect. Essentially, this respect was a type of social capital that the man could exchange for political capital in a informal power structure. At times this leadership structure was stronger than others. Sometimes the elders of the village were distinguished in their position of authority, such as the times they perform religious tasks for the community. However, even when the role of the village leaders if defined they feel a responsibility to the community, as the only members of the society qualified to fill such prescribed roles. These social responsibilities did not officially come with their titles. Umuofia seemed to function on a consent basis, meaning that each person had to choose to keep society running smoothly. It was not uncommon for all the men to be called together to make a collective decision. For example, all the men of Umuofia were called to one large corporate meeting to decide a course of action when a neighboring village murdered a woman from their village. At this meeting, the elders of the community had no official political distinction, however, the respect accorded them by their social position helped their voices to be heard. Consent and collectivity were major facets of the Umuofian society that allowed for informal leadership. For example it is said that the â€Å"the village [collectively] imposes† a fine on anyone who lets his cow loose (Achebe, 68). The reason that Igbo society could function with such informal structure was the importance and knowledge of traditions. These traditions were taught to the children and young adults so that they would be able to participate in the script of village life. It is almost as if these formal traditions allowed for the informal leadership structure by tacking the role as the backbone of society. Nearly all aspects of life in the village were run by such formal traditions. For example, upon receiving a visitor, the owner of the house always presented a Kola nut, which they ate together as a sign of hospitality. The meeting of all the men is an additional example of this tradition because it was organized by a system of drums and â€Å"callers† under the expectation that the people would be able to interpret the call (Achebe, 8). There is social power in knowledge of these traditions. Kinship was an additional level of social control in the village of Umuofia and had two social consequences. Kinship was traced through patrilineage, with great respect given to the eldest male members of the family. This familial hierarchy reproduced the traditions that dictated social interactions by instilling these customs in the younger generations. The second consequence was the ties of kinship that connected the nine Igbo villages. While descent and clanship was traced through the father’s line, intermarriage among the villages created ties to the mother’s village and connected multiple clans. In this way, the Igbo society maintained nine autonomous, though interlinked, villages without a direct formal hierarchy of social or political power such, as a head chief or king between them. The greatest of all elders were the ancient ancestors and founders of Umuofia. These ancestors essentially filled the highest political roles in the village. They resided as judges over disputes and gave advice in troubled times. In this way it was not necessary, and would in fact have been an insult to the ancestors, for a man to fill the highest political role in the village because the ancestors had the final power anyway (Achebe, 55-57). It was said that â€Å"the land of the living was not far removed from the domain of the ancestor† and that â€Å"a man’s life from birth to death†¦brought him nearer and nearer to the ancestors† (Achebe, 73). The deep complexity of Umuofian society meant that colonialism’s effects were devastating to the village’s way of life. The British administration which colonized the area did not understand the Umuofian traditions and instead decided to treat them like children who needed to be taught the proper ways of society (Achebe, 109). The beliefs and practices of the Christian missionaries were especially in contradiction to the traditions and beliefs that structured Umuofian society because the missionaries considered the ancestors to be false gods. They preached against them and effectively left the society without leaders. The colonial administration always saw situations from their perspective. As Achebe says â€Å"they had built a court where the district commissioner judged cases in ignorance† (99). For example, the British punished the elders of the clan for destroying the missionaries’ church because they thought they had the responsibility to keep order in the colony, while the clan leaders had thought they too were keeping order in the community by avenging the death of an ancestor and had the right to do so because it was their community. To compare the political structures of these two cultural groups, in Britain one person had ultimate political power, and society enforced this power, while Umuofian society required cooperation of all members and thus, I believe, showed a greater level of social integration than Britain, which relied heavily on its chain of command in order to function. Because of the intricacies of Umuofian society Britain was able to destabilize the whole of Umuofian society simply by affecting certain aspects of the society. Inversely the Umuofians would have had to dispose of the Queen of England to bring down the colonialists.

1984 and Brave New World Essay -- 1984 Brave New World

1984 and Brave New World Undoubtedly, the thought of living in, or forming a utopian society has flashed through nearly every person’s mind. A few people have even tried to make this ideal dream society a reality. Unfortunately, within the pursuit of these societies the leaders become corrupt and begin to become paranoid with the fear of rebellion. Hundreds of people were murdered during the reigns of Adolph Hitler and Joseph Stalin in what they considered measures to maintain peace and stability within their respective â€Å"perfect† society. One must also consider the hardships that the citizens were forced to endure while living under these oppressive governments. This dream of forming and maintaining a utopian society was immortalized in two novels dealing with the same basic ideas, 1984 by George Orwell and Brave New World by Aldous Huxley. Both of these novels deal with the lives of main characters that inadvertently become subversives in a totalitarian government. These two books differ greatly however with the manner in which the government controls the population and the strictness of the measures taken to maintain this stability. This essay with compare and contrast the message and tone of each novel as well as consider whether the utopia is a positive or negative one. In 1984, George Orwell explores the many facets of a negative utopia. Orwell seems to focus on the measures that the government takes to maintain a public of plebeians who have no personality or identity and believe that they are not unique individuals, but instead are part of a greater senseless mob of people who constantly work for a hostile and oppressive government which is involved in incessant wars. These people are taught to love. They then learn to fear their government because they believe all of the propaganda that is constantly instilled into their minds. They willing follow their government without contest for the duration of their meaningless lives. The government controls all forms of the media (thus denying the people the basic right of free speech) and use it to personify the government (known as â€Å"big brother†) .The government therefore seems omnipotent, or all knowing and always correct. Forecasts are changed from one week to the next always proving the g overnment was correct. As was mentioned before, many of the rights that present day Westerners take for gran... ...nly contemplate living as an alpha or beta because we cannot contemplate living without being able to formulate ideas or basically think. No one considers living as one of the lower castes and only working throughout life until death. Thus, it seems that Huxley intended to portray an acceptable society on the surface with undesirable traits hidden deeper. In conclusion, both of these novels portray an attractive life in a utopian society, if one can conform to the rules. When people cannot conform to the societies in which they dwell (as the main characters of both novels cannot) they are branded as subversives and punished as traitors. Life in 1984 would be almost too unbearable to live. Life in Brave New World is only acceptable if one is willing to live a life of the caste one is in, that is to produce (as a lower caste) or consume (as a higher caste). This essay has compared the differences between the societies in these two novels. There is one great similarity however that both make me thankful for having been born into a freethinking society where a person can be truly free. Our present society may not be truly perfect, but as these two novels show, it could be worse.

The Voice

You may adore it, you may despise it well guess what I love: The Voice. Well if you have not heard of it; let me give you some insight into it. It`s a British television talent show based on ‘The Voice Of Holland’ created by the Dutch television producer John De Mol. It began its 11 week run in March 2012. There are four stimulating and appealing judges to judge the voices of the contestants; more over the judges are Danny O’Donoghue who is absolutely good-looking; there’s Jessie J who sings absolutely flawlessly; followed by Sir Tom Jones who is totally a legend; last but not least Will.I. Am who is extremely hilarious! As soon as I saw that they were the judges I literally jumped off my feet and started screaming! As you could see all the judges are singers moreover they aren’t producers or other music executives as an alternative they are famous recording artists who represent a range of musical genres. OMG the presenters are Reggie Yates and Holl y Willoughby. I absolutely admire Reggie Yates and Holly Willoughby well I'm not fond of her that much, yet she’s alright.Well I haven’t even mentioned why I think highly of ‘The Voice’ yet! I admire it because it’s different compared to all the other different talent shows, for instance: X-Factor and Britain’s Got Talent. In addition, The Voice is judged based on their voice and not accordingly to their appearance as the auditions are ‘blind auditions’ meaning that the judges back are turned towards the contestant, so that they can’t see who’s singing, which I think is superior!Thus if the judges liked the voice they would buzz to see who’s behind the voice. If there’s more than one judge that buzzed the contestant gets to chose who they want as their mentor throughout the competition. Which I personally think is the most thrilling part of the auditions to see who they pick and who I think they are go nna pick. Besides, I forgot to say I also Love the songs they sing throughout the competition, mainly because I’ve heard of them before, as a result they are my variety of music! So what are your thoughts?Well, Isabel Mohan says â€Å"The Voice failed because it was so nauseatingly nice† along with Aiden Merrygold says â€Å"I find this show pointless as we already have an X-Factor and Britain’s Got Talent and I think that’s enough! However, I don’t care what others say about this show it’s their opinion and my opinion is I find this show irresistible. Well, so far of the first series on the whole much-loved episode was the semi – finals one, where the contestants sang with their mentors for the very first time! It was exciting as well as intriguing to see what song they would sing and sort of genre they would pick!However, the battle rounds were very electrifying to watch, as all the contestants were incredibly good singers moreover it was sad to see a few of them leave. So, what are the battle rounds? Do you know? Well, let me tell you a bit about it. During the battle rounds the contestants are coached by judges and mentored by an additional recording artist they are known as ‘advisers’. The battle pits two of a judge’s singers against each other they must sing the same song in front of a studio audience. After, the judges have to choose which of their own singers must go home.

Drama coursework †Response Essay

Introduction In our group we came up with lots of similarities in our thought showers. A lot of us described the Witches the same as in the green faces, long noses warts & spots, and there broom sticks. Some differences that our group came up with is that a few of us thought of modern witches, as in a normal human being look but with witch features, instead of black cats a lot of our group wrote different pet names. Our mind has been influenced about the topic by many things e.g. the media’s outlook on a stereotypical witch, children’s stories also portray witches with the green faces big hats etc. which means movies portray it like this. Also from the image created by our ancestors where the apparent witches were being burnt at the stake. Macbeth extract: focusing on the ‘outsider’ This role-play brought about issues such as how society today fears outsiders. How society today is divided into different groups, such as Goths / punks / gangster and take different paths in life. We fear the outsiders of society because we fail to understand the logic behind their culture / background. This also brings about racism / religion clashes. In the olden days most of the fear was based around witches because they were conveyed as the biggest outsiders. The storyline of our role-play was about a gothic boy who was feared & isolated from family & school because of being a Goth. We started the role play with Steven (the gothic boy) being in a school photo where is he is isolated from the rest of the school and then we went into his home life where his parents & siblings make jokes about his appearance and his way of life. We ended the play with a twist, where Steven was with all his gothic friends and his little brother (Aaron Tovee) walks past Steven and his group of gothic friends and is mocked for being what society would call â€Å"normal† and he is then conveyed as the outsider. We showed isolation in this play from the very first scene. In the first scene we had school photos were Steven (the outsider) was separated a foot away from the rest of the school that were huddled together for the photo. We portrayed an even bigger sense of frustration & isolation by this when the photographer asks Steven to step in the photo and the group moves away from him. The photographer blames Steven and again snaps at Steven to move into the photo. We did this to show how normal society blames the outsider, as if it was just easier to do so. We also showed isolation at the dinner table of Stevens’s family-home. We showed this by having all his siblings laugh and snigger at him and make comments like â€Å"drink blood† because of his gothic background. We ended that scene with Stevens father shouting at Steven telling him he’s not welcome in the home for kicking his sibling under the table (for making the comments) and telling him to get out and hang around with ‘his own kind.’ This made the whole idea of isolation seem a lot more effective because even his father, he whom he should be very close with, kicks him out of the house belting abuse at the top of his voice just because he is a Goth. We also ended our role-play with a twist on the sense of isolation where Steven is with a group of his Goth friends when his little brother walks past and his little brother feels isolated and afraid because he is the outsider there. The crucible Some similarities of ideas that we had on the idea of witchcraft from this stimuli went along the lines of how accusations were so quickly thrown around in the courtroom, and how everyone believed someone who was called a witch. Most people also thought that it was a fairly racist time and that’s why if you was black like the maid in the stimuli the blame was easily put on you. Some differences on the stimuli were about how the accused always showed a sense of fear. How society was so gullible and why the lies were started. In our role play we showed the accusation by the same sort of scene as the stimuli. We had it set in a court-room in the olden times whereas the judge’s verdict was the final, and punishment was death / something incorporating pain. We built hysteria in our role-play by levelling up the amount of volume in the courtroom until it was mayhem and chaos with everyone throwing accusations of being a witch to the accused. We marked the moment where the defence is getting shouted at and abused really badly and she gets up and accuses a man from the courtroom audience. We did this by building up the hysteria with everyone standing up shocked, and built up amount of noise slowly to a really loud volume and then when she got up and said â€Å"It’s him!† we silenced the courtroom immediately so it was just a big awkward silence. Studying this stimulus helped us understand the context at the time because it showed how gullible society was at that time period. An example of this is the fact that everyone believed that a person was a witch just by someone else’s word. The stimulus also shows that there was a big thing about racism in that time. An example of this is where the black woman was blamed for being the witch and beat brutally, the accusation was easily accepted by society because of the colour of her skin. Forum Theatre. Our class used forum theatre through studying a news article about a woman sacrificing her two babies to Satan. We then used this as a stimulus and did a whole-class courtroom drama, where we would switch places (defence, prosecution, judge, witnesses etc) This was useful to use because it made you think on the spot about the subject and it also improved your improvisation skills. Using the court-room drama attached with forum theatre was very useful because reading about just the sacrifice gave you a biased opinion about what really happened. But when we used the courtroom drama we had to act as defence as well so you started thinking about both sides of the story, and maybe reasons for why they did it. When playing the witnesses it also opened up that it might not just affect the family it could also affect other people around too. Conclusion My understanding of the topic has developed through studying the different stimuli a lot because you start to realise that witchcraft isn’t all fairytales and children’s books. It can be portrayed through children’s theatre, but also relate to serious events such as when the babies were sacrificed by the mother to Satan and such. Studying the different stimuli in different times and cultures developed our Understanding a lot too because you can see that not along ago was it that people actually were killed for being accused of witches, and everything was done through religion, and people believed in God strongly. You can see that science has developed through the ages and changed the thoughts of people today drastically through things such as the theory of evolution, which puts people in 2 minds about the creation of mankind, and even questions religion. Therefore people aren’t willing to believe things like witchcraft anymore as it has become abnormal for us to comprehend supernatural things.

Definition of X- Internet Essay

Many people think the Internet and the Web are the same thing. They’re not. The Internet is a piece of wire that goes from me to you and from me to 300 million other people in the world. The Web is software that I put on my end of the wire, and you put on your end — allowing us to exchange information. While the Internet (the wire) evolves gradually, the software on the wire can change quickly. Before the Web, other software was clamped onto the Internet. WAIS, Gopher, and Usenet were the dominant systems, and there were companies that were doing commerce using those software models. I call this the â€Å"executable Internet,† or X Internet, for short. X Internet offers several important advantages over the Web: 1) It rides Moore’s Law — the wide availability of cheap, powerful, low real-estate processing; 2) it leverages ever dear bandwidth — once the connection is made, a small number of bits will be exchanged, unlike the Web where lots of pages are shuttled out to the client; and 3) X Internet will be far more peer-to-peer — unlike the server-centric Web. This scenario could be marred by two threats: viruses and lack of standards. Once executables start to move fluidly through the Net, viruses will have perfect conditions to propagate. Standards, or rather the lack thereof, will block the quick arrival of X Internet. I can’t see Microsoft, Sun, IBM, or other traditionalists setting the standards. The Web-killer’s design will emerge from pure research, academe, or open source — as did the Web. What It Means — No. 1: Web-centric companies get stuck holding the bag. They will wake up one day with hundreds of millions of dollars of legacy code on their hands. Yes, their brands will remain intact, but their technology will suddenly be very outmoded. Yahoo!, eBay, and AOL will find themselves competing with a new wave of commerce players that market, deliver, and service using the superior technology of X Internet. One of the upstarts will Amazon Amazon. What It Means — No. 2: Investors get happy. The new wave of startups will race to market with X Internet, blasting old Web infrastructure and commerce companies out of their path. Internet creative destruction, round two. What It Means — No. 3: Peer-to-peer (P2P) networking rockets. The X Internet’s â€Å"smarts everywhere† design will enable an epidemic of Napstering. Courts, legislators, governments, companies, and other rule makers will have to contend with an empowered and ever more  liberated, unruly populace — armed with technology that allows them to bypass economic toll roads and bridges. What It Means — No. 4: If you are a Global 2,500 company, get ready for another round of change. This means: 1) overhauling the skills of your technologists; 2) destroying perfectly good Web sites in favor of the X Internet; 3) dumping Web-centric suppliers; and 4) retooling organizations. Change management will get a new test. As the Internet expands, two new waves of innovation — comprising what Forrester calls the X Internet — are already eclipsing the Web: an executable Net that greatly improves the online experience and an extended Net that connects the real world. An executable Net that supplants today’s Web will move code to user PCs and cause devices to captivate consumers in ways static pages never could. Today’s news, sports, and weather offered on static Web pages is essentially the same content presented on paper, making the online experience more like reading in a dusty library than participating in a new medium. The extended Internet is reshaping technology’s role in business through Internet devices and applications which sense, analyze, and control data, therefore providing more real-time information than ever before about what is going on in the real world. The X Internet will not be a new invention, but rather the evolution of today’s Internet of static Web pages and cumbersome e-commerce mechanisms into a Net that relies on executable software code to deliver more interactive experiences. Executable Internet applications use downloaded code like Java and XML to enhance the user experience with pop-up menus, pick lists, graphics and simple calculations, according to a recent Forrester report entitled â€Å"The X Internet.† An easy way to understand how the X Internet will work is to imagine that a band wants to distribute asong over the Net. Rather than worrying about which audio player people want to use, an executable file will deliver the song and the audio player at the same time. â€Å"With an executable, you can distribute movies the same way you distribute songs,† Forrester research director and report author Carl Howe told NewsFactor Network. â€Å"It just makes the models work better.† Building the X-Net The report also employs an example of a person building a house. With today’s  Internet, a builder would have to find, then try to follow, an article detailing how to frame a window. When it was time to installthe bathroom, the would-be plumber would then have to find an article dealing with that topic. Executable Internet applications would demonstrate to a builder, step-by-step, how to frame a window. When it came time to install the bathroom, the carpenter would simply be replaced by a plumber. â€Å"Instead of reading a book, you have a conversation about the work you’re trying to do,† Howe wrote. Forrester is also predicting the widespread adoption of another X Internet — but this X stands for â€Å"extended.† The extended Internet will include the widespread adoption of real-world appliances, like air conditioners or car tires, that communicate with owners or manufacturers via the Internet. The extended Internet will come with the inclusion of cheap sensors in thousands of everyday products, an era that will begin around 2005, Forrester predicts.

Wireless Networked Digital Devices The proliferation of mobile computing devices including laptops, personal digital assistants (PDAs),and wearable computers has created a demand for wireless personal area networks (PANs).PANs allow proximal devices to share information and resources.The mobile nature of these devices places unique requirements on PANs,such as low power consumption, frequent make-and-break connections, resource discovery and utilization, and international regulations. This paper examines wireless technologies appropriate for PANs and reviews promising research in resource discovery and service utilization. We recognize the need for PDAs to be as manageable as mobile phones and also the restrictive screen area and input area in mobile phone. Thus the need for a new breed of computing devices to fit the bill for a PAN. The above devices become especially relevant for mobile users such as surgeons and jet plane mechanics who need both hands free and thus would need to have â€Å"wearable† computers.This paper first examines the technology used for wireless communication. Putting a radio in a digital device provides physical connectivity;however,to make the device useful in a larger context a networking infrastructure is required. The infrastructure allows devices o share data,applications,and resources such as printers, mass storage, and computation power. Defining a radio standard is a tractable problem as demonstrated by the solutions presented in this paper. Designing a network infrastructure is much more complex. The second half of the paper describes several research projects that try to address components of the networking infrastructure. Finally there are the questions that go beyond the scope of this paper, yet will have he greatest effect on the direction,capabilities,and future of this paradigm. Will these networking strategies be incompatible, like he various cellular phone systems in the United States, or will there be a standard upon which manufacturers and developers agree, like the GSM (global system for mobile  communication)cellular phones in Europe? Communication demands compatibility, which is challenging in a heterogeneous marketplace. Yet by establishing and implementing compatible systems, manufacturers can offer more powerful and useful devices to their customers. Since these are, after all, digital devices living in a programmed digital world, compatibility and interoperation are possible. Introduction to X internet : X internet seminar topic explains about concept of new generation internet applications and its updations in software and hardware technologies. Concept of x internet will help in different aspects of businesses, education and power full ways then present standards that we see in internet. Using this technology users can connect to physical objects by adding intelligent technologies which will increase connectivity between humans and physical objects. In this paper we provide detailed explanation on the extended internet, advanced cooperative wireless technology, context awareness, built in intelligence and more.

Politics Aquinas Essay Example | Topics and Well Written Essays - 1000 words

Politics Aquinas - Essay Example However, despite influences on Aquinas from the political climate of that time, we can perhaps find out the essence of his view on the mentioned problem that still would be relevant for our todays situation. Thomas Aquinas lived at a pivotal period for the Western philosophy when the return of the Aristotelianism combined with scholasticism to reignite debates about the correlation between reason and faith. Aquinas became fully acquainted with this school of philosophy after he joined the Dominican Order and for several years studied with Albertus Magnus (1193-1280), a scholastic philosopher who worked on restating of the Aristotelian heritage. This acquaintance of Aquinas is considered to be the most significant influence on his world view, which turned him into an erudite scholar devoted to the Aristotelian method (McInerny, 1992, p. 16). In general, Scholastics of that time promoted empiricism and voiced support for policies and doctrines of the Roman Catholic Church. They stood in opposition to Christian mysticism as well as to concepts of dualism of mind and of the evil nature of the world promoted earlier by Plato and St. Augustine (McGrade, 2003, pp. 33-34). What interests us in relation to the problem that we have raised is Aquinas' theory of natural law. To better understand this theory, it must be pointed out that Aquinas views philosophy as a general term which relates to a set of sciences. To diverse philosophical fields Aquinas ascribes the following due order for their study: logic, mathematics, natural philosophy, moral philosophy, and metaphysics, which is the apex of philosophical study. Aquinas' theory of natural law concerns moral philosophy, for which the notion of the human good is central. Aquinas sees a difference between acts of a man and human acts, as the former acts can be also seen in non-human agents, while human acts stem from knowledge and will and always aim at a known good. But Aquinas points out that as a certain good is not the same as the goodness itself, then what holds together all the human actions is what he terms as the overarching goodness which is the ultimate end. Therefore, any human action is direct ed towards the ultimate end (Lisska, 1998, pp. 132-133). Now that we have uncovered the basic ground of the morality for Aquinas, we can better understand his views towards what he called the natural law. In fact, what forms the essence of the natural law moral theory is the view that morality stems from the nature of the world and of the human beings. For Aquinas, main morality-generating principle of human nature is its rationality, for instance manifested in human pursuit of a certain good, which underlies any moral law. Therefore, as humans are born rational, it is morally right to behave in correspondence with our rational nature. In this way Aquinas connects moral laws with the human nature and this connection forms the basis of the "natural law", that
