Critical appraisal of a public health research article - Assignment Example 4). The lifestyle changes involve physical activity, balanced diets and loss of weight or the commonly called obesity. The research concluded that with 12 months follow ups the proposed lifestyle changes had significant positive effects towards control and prevention of type 2 diabetes. The research used the intervention design that was appropriate and served the purpose of addressing the aims of the research (Linda, et al, 2013, p.10). The research brought together a group of people that were assessed individually on the risk of type 2 diabetes. The New Leadership New York that is a competent group in the UK did the assessment. The selected population was required to be assessment weekly while those at high risks were assessment twice every week. The diet, weight and waist size of the population was recorded on each assessment. The NLNY involved the selected population with a half an hour practice session that was followed by a group reflection of the same period. The practice session involved a gym activities and cookery sessions and was very relevant since the research aimed at the two activities in relation to type 2 diabetes (Mokdad and Bowman, 2001, p.1196). The design was viewed as a ââ¬Ëdo and reflectââ¬â¢ model since the trainers demonstrated the act ivities and gave chance to the selected population to rehearse the activities (National Diabetes Data Group, 2013, p.1041). The design was flexible since it gave chance to the selected population to choose the physical activities of their choice The selected population went through a lot of education and on completion of the training, they were also allowed to access gyms for free. After the training, follow up plans by the NLNY were made through texts and emails to remind the trained individuals on the maintenance of lifestyle changes . Interviews were conducted after six months to evaluate on the level of success in terms of fighting diabetes to the trained

Efficient Xml (extensible Markup Language) and AJAX - Essay Example n be used all the way through the organizations, allowing the description, communication, corroboration, and interpretation of data among applications and between organizations. XML has also verified its usefulness for connecting inherited information to the Web, for the reason that the XML tags are utilized to describe data as it is configured in the legacy data lay up, therefore eradicating the necessity to reconfigure it. XML is quickly turning out to be a standard for e-commerce content. While HTML, documents oversee the demonstration of data and information in a Web browser, XML deals with the configuration and handling of the data engaged. Consequently, XML makes it feasible to store data objects that are constantly established all the way through the businesses, and XML is turning out to be the standard for e-commerce data exchange. XML is not substitute for HTML; however it performs its job with HTML to assist the transmission, exchange, and handling of data. Therefore, all c ategories of content can be arranged by means of XML, such as images files and sound files. Data that need to be distributed outside the organization should stick to widely defined XML framework. On the other hand, inside data should be defined particularly in XML (Hoffer, Prescott, & McFadden, 2007) and (Hoffer, Prescott, & McFadden, 2007, pp. 399-400).The trend of using XML as a constant storage arrangement is becoming more and more widespread for the configuration of data and information, as a transitional database layout, as well as for semantic annotation (MSDN, 2007). The procedure of standardization is itself an enormously complicated one. If one planed a standard too soon, the standard does not regard as sufficient information and is consequently not assumed. If the standard is planned excessively late, as well a lot of people will have assumed their own methods, and the standard will be unnoticed. A number of instances of standards that came too soon or too behind include,

Epistemologies; Plato vs. Aristotle Essay Example for Free
Epistemologies; Plato vs. Aristotle Essay Plato, the father of philosophy, was a rationalist. He was the first systematic metaphysician and epistemologist. He believed that we had innate knowledge; a priori. So to him learning was only a matter of remembering. Plato believed that the ââ¬Å"idealâ⬠world existed beyond our own physical earth because according to him realty could not be changing or imperfect. From his point of view what we see are only the particulars, the mimics of the real thing, therefore, we have to pull back from the world of peculiars and search in our own minds. Things like justice or moral virtues do not exist in this world in a proper form. In Crito Meno we can clearly see these ideas. The essential argument in Crito is ââ¬ËThe Many vs. The Oneââ¬â¢. Socrates says ââ¬Å"We shouldââ¬â¢t care all that much about what the populace will say of us, but about what the expert on matters justice and injustice will say, the individual authority, or Truth. â⬠With this phrase he is saying that we should never pay attention to the opinion of the many but always find the one who knows because that is the only person whose opinion is valuable. And later on he goes on to say that if it is never good to do injustice then it is also wrong to do injustice in response to injustice which is why he refuses to escape. In Meno we get more in depth into the idea of inborn knowledge. Meno starts with the question ââ¬ËWhat is Virtue? ââ¬â¢ but Meno always answers the question by giving examples of virtue instead of defining the word and going to the roots of what all those virtues have in common. Down in the world of particulars there are many kinds of virtues for example for the male itââ¬â¢s to run the state, female itââ¬â¢s to run the household but what is important, essential is the traits they both have in common; temperance and justice. Socrates uses the dialectical method in order to get answers out of Meno and also clearly demonstrates this method on a slave of Meno to prove his theory about innate knowledge. Even though it can always be used, using the dialectical method is specifically significant when a person believes that we have innate knowledge, because if what we call learning is just remembering then teaching is just pulling out that knowledge, giving opportunities for that innate knowledge to spring forth. Aristotle on the other hand was an empiricist. He believed that we ââ¬Å"learnedâ⬠through our senses, by gathering knowledge from the world around us; ââ¬Å"a posterioriâ⬠. By reading ââ¬ËOn the soulââ¬â¢ and ââ¬ËMetaphysicsââ¬â¢ we get a clear sense of Aristotleââ¬â¢s epistemology. Aristotle encourages embracing the particular in order to possibly gain a sense of the universal. According to Aristotle forms are the essence and when we combine form and matter we get human. The reading ââ¬ËOn the Soulââ¬â¢ discusses that the body and the soul is not one, that sight allows us to absorb the world in very abstract ways and that memory is learning. In the reading ââ¬ËMetaphysicsââ¬â¢ Aristotle sets forth causes for the explanation of change: Substance (essence), Matter (or substratum), Source of change and the cause opposed to this. Plato and Aristotle both believed in a universal purpose but the ways in which they got to these universal purposes were very different. Plato was an idealist, he despised the physical whereas Aristotle was a scientist, he loved facts and commonsense. Aristotle would argue that we gain knowledge after experience (a posteriori) but Plato would certainly disagree and say that we gain knowledge before experience (a priori). Plato believes that there is a world of ideas where ideas exist perfectly, the objects in our world are just mimics whereas Aristotle says that the ideas we perceive are inside the particular object. By saying that matter and form combined is what makes an individual Aristotle brings Platoââ¬â¢s Forms ââ¬Å"down from the heavens to concrete reality. ââ¬

The Perils of Obedience by Stanley Milgram Essay -- Stanley Milgram T
ââ¬Å"The Perils of Obedienceâ⬠was written by Stanley Milgram in 1974. In the essay he describes his experiments on obedience to authority. I feel as though this is a great psychology essay and will be used in psychology 101 classes for generations to come. The essay describes how people are willing to do almost anything that they are told no matter how immoral the action is or how much pain it may cause. à à à à à This essay even though it was written in 1974 is still used today because of its historical importance. The experiment attempts to figure out why the Naziââ¬â¢s followed Hitler. Even though what he told them to do was morally wrong and they did it anyway. If this essay can help figure out why Hitler was able to do what he was then able to do, then maybe psychologists can figure out how to prevent something like that from happening again. à à à à à ââ¬Å"The Perils of Obedienceâ⬠is about an experiment that was made to test the obedience of ordinary people. There are two people who come and perform in the lab, one is the subject or the teacher and the other is an actor or the learner. The teacher doesnââ¬â¢t know that the learner is an actor. They are there to see how far someone would go on causing someone pain just because they were told to do so the authority figure. The learner is given a list of word pairs and has to memorize them.

Macbeth Soliloquy Analysis Essay
Lady Macbethââ¬â¢s Unsex Me Soliloquy Analysis In 1.5. 36-53 of Shakespeareââ¬â¢s Macbeth, Lady Macbeth delivers a sullen soliloquy which expresses her ambitious yet murderous thoughts, invoking dark spirits to, first, change and destroy her feminine nature, second, to let her feel no fear or guilt upon doing wicked acts such as murder, and then, third, to cover all of her vile and vicious crimes. By doing so, Lady Macbeth vividly reveals to the audience her dark, destructive, and true nature. From lines 36-42, Lady Macbeth expresses her desires to erase her femininity, conjuring dark forces to ââ¬Å"unsex her and fill [her] from the crown to the toe, top-full of direst crueltyâ⬠(40-42). Not wanting to be a female with a heart filled with love, kindness, and pity, Lady Macbeth would rather strip off all of her femininity along with these pure feelings, and acquire a vile and vicious nature which will not allow her to hesitate when carrying out devilish deeds, such as murder. Secondly, upon hearing about the witchesââ¬â¢ prophecy about Macbethââ¬â¢s future, Lady Macbeth already showed intentions of killing the king, and therefore summons evil spirits to ââ¬Å"Make thick [her] bloodâ⬠. By making thick her blood, it will obstruct the passage for fear, guilt, or remorse, and would allow her to perform destructive and evil acts without those natural emotions in mind. Additionally, Lady Macbeth calls to murdââ¬â¢ring ministers (48) to ââ¬Å"Take [her] milk for gallâ⬠, which expresses her thoughts about wanting to take away her kindness and substitute if for bitterness, and too remove all the purity in her, allowing her to become a murderous and evil being. Lastly, Lady Macbeth pleads the spirits and demons to hide her vicious crime she will commit in the future by covering it up with pure darkness: Come, thick night, And pall thee in the dunnest smoke of Hell, That my keen knife see not the wound it makes, Nor Heaven peep through the dark Although Lady Macbeth truly wants to murder the king, she does not want her crimes to be revealed. By covering her evilness with darkness, her knifeà which murders will not see what evil deed it has done, and heaven will not be able to even glance at the crime sheââ¬â¢ll have committed, which will allow Lady Macbeth to murder the King with no fears or worries about being caught. In conclusion, as Lady Macbeth calls to evil spirits to take away her femininity, to feel no remorse or guilt after performing the deeds of evil, and finally to cover her murderous action with darkness, she reveals to the audience her that she is willing to do anything to get what she wants, which let us conclude that Lady Macbeth is an ambitious and fearless character with a mind full of corruption, destruction, and darkness.

Abbreviation with Names and of Titles
Abbreviation with Names and of Titles Abbreviation with Names and of Titles Abbreviation with Names and of Titles By Mark Nichol This post outlines major conventions regarding the use of initials and abbreviations in association with peopleââ¬â¢s names. Periods are used with initials in names (ââ¬Å"W. E. B. Du Boisâ⬠) unless someone is referred to exclusively by his or her initials (ââ¬Å"FDRâ⬠). Note, too, that in formal writing, a space separates each initial used in a full name, as shown in the first example here, though periodicals and other less formal publications generally omit the spaces (ââ¬Å"W.E.B. Du Boisâ⬠). Civil or military titles are often abbreviated before a full name but not before a surname alone (ââ¬Å"Sen. Elizabeth Warren,â⬠but ââ¬Å"Senator Warrenâ⬠), although inclusion of the title with the surname is generally not necessary. (In this case, Warren alone is suitable for subsequent references to the person after the introduction of her by her full name.) In situations in which space is at a premium, as in a chart or table, abbreviation can be applied more liberally, and in that case itââ¬â¢s best to be consistent within the graphic element even if sufficient space is available with some names but not others. Social titles such as Mr. and Ms. are rarely used in published writing anymore, except in quoted material, and are redundant when initials designating an academic degree or professional attainment follow a name. (For example, in the phrase ââ¬Å"Dr. Jane Smith, MD,â⬠Dr. and MD are two ways of expressing the same information.) Note that such references as MD, or CPA (for ââ¬Å"certified public accountantâ⬠), are appended to a name enclosed between commas, but when abbreviations such as Jr. and III follow a name, no intervening punctuation is necessary (as in ââ¬Å"John Smith Jr. was honored at the ceremonyâ⬠). In narrative, spell out titles such as ââ¬Å"the Reverendâ⬠and ââ¬Å"the Honorableâ⬠before a full name (and do use the article), but they can be abbreviated as Rev. or Hon. (without the article) in a list. When referring to a saint, spell out that word unless space is limited; St. is the correct abbreviation. (When the word or abbreviation appears in a personââ¬â¢s name, honor the style that person uses.) Most titles specifying oneââ¬â¢s role in a company or organization are generally not abbreviated, but one exception is often made for the most senior executive, the CEO (ââ¬Å"chief executive officerâ⬠). That title is often abbreviated without a full spelling on first reference, though titles for others, such as ââ¬Å"chief operating officer,â⬠who work in what is known as the C-suite (because the first word of the job titles for these people is chief, abbreviated with a capital c) are usually spelled out. (Specialized publications catering to an audience familiar with such titles often abbreviate them on first reference, however.) Want to improve your English in five minutes a day?

Evolution Labs - Coacervates Lab
Evolution Labs - Coacervates Lab Coacervates are a life-like creation that prove that life may have formed from simple organic substances under the right conditions that eventually led to the formation of prokaryotes. Sometimes called protocells, these coacervates mimic life by creating vacuoles and movement. All it takes to create these coacervates is protein, carbohydrates, and an adjusted pH. This is easily done in the lab and then the coacervates can be studied under a microscope to observe their life-like properties. Materials: goggleslab coats or protective covering for clothescompound light microscopemicroscope slidescoverslipstest tube racksmall culture tubes (one tube per student)rubber stopper or cap that fits the culture tubeone medicine dropper per tube0.1M HCl solutionpH papercoacervate mix Making the coacervate mix: Mix 5 parts of 1% gelatin solution with 3 parts 1% gum acacia solution on the day of the lab (the 1% solutions can be made up ahead of time). Gelatin can be purchased at either the grocery store or a science supply company. Gum acacia is very affordable and can be bought from some science supply companies. Procedure: Put on the goggles and lab coats for safety. There is acid used in this lab, so extra precautions should be taken when working with the chemicals.Use good lab practices when setting up the microscope. Make sure the microscope slide and coverslip are clean and ready for use.Obtain a clean culture tube and a test tube rack to hold it. Fill up the culture tube about half way with the coacervate mix which is a combination of 5 parts gelatin (a protein) to 3 parts gum acacia (a carbohydrate).Use a dropper to put a drop of the mix onto a piece of pH paper and record the initial pH.Add a drop of acid to the tube and then cover the end of the tube with a rubber stopper (or culture tube cap) and invert the entire tube once to mix. If this is done properly, it will turn somewhat cloudy. If the cloudiness disappears, add another drop of acid and invert the tube once again to mix. Continue adding drops of acid until the cloudiness stays. Most likely, this will not take more than 3 drops. If it t akes more than that, check to be sure you have the right concentration of acid. When it stays cloudy, check the pH by putting a drop on pH paper and record the pH. Place a drop of the cloudy coacervate mix on a slide. Cover the mix with a coverslip, and search under low power for your sample. It should look like clear, round bubbles with smaller bubbles inside. If you are having trouble finding your coacervates, try adjusting the light of the microscope.Switch the microscope to high power. Draw a typical coacervate.Add three more drops of acid, one at a time, inverting the tube to mix after each single drop. Take a drop of the new mix and test its pH by putting it on the pH paper.After washing your original coacervates off of your microscope slide (and the coverslip, too), put a drop of the new mix on the slide and cover with the coverslip.Find a new coacervate on low power of your microscope, then switch to high power and draw it on your paper.Be careful with clean up of this lab. Follow all safety procedures for working with acid when cleaning. Critical Thinking Questions: Compare and contrast the materials you used in this lab to create coacervates to the supposed materials available on the ancient Earth.At what pH did the coacervate droplets form? What does this tell you about the acidity of the ancient oceans (if it is assumed this is how life formed)?What happened to the coacervates after you added the extra drops of acid? Hypothesize how you could get the original coacervates to come back into your solution.Is there a way coacervates may be more visible when looking through a microscope? Create a controlled experiment to test your hypothesis. Lab adapted from original procedure by the University of Indiana

Little italy Research Paper Example | Topics and Well Written Essays - 1000 words
Little italy - Research Paper Example However, Italian Harlem is currently composing of more Spanish Americans as compared to those from Italian origin. In this regard, Little Italy in lower Manhattan serves as a perfect representation of Italian populations in modern America. Currently, Little Italy in New York is characterized by numerous restaurants selling Italian cuisine. In addition, streets along this region are laced with several convenience stores selling products preferred by Italian consumers. History of Little Italy Historically, Little Italy in Manhattan was founded in the late 19th Century during immigration of Europeans into the US. Supposedly, Europeans from different countries including Spain, Italy and Britain were moving in mass numbers into the US. During the movement, thousands of Italians entered into the United Stateââ¬â¢s west coast. Since Europeans preferred urban settlements, most Italians moved from the cost and settled in areas around New York metropolitan. In 1910, population of Americans from Italian ancestry living in the region was approximately 10000. This does not mean that the entire population of Little Italy was ten thousand. Other people, especially Chinese immigrants were living with Italians within the city. As of 2011, demographic statistics shows that Little Italy comprised of approximately 1200 Americans from Italian ancestry. Vincenza (2008) says that through the ages, residents in this region continually move from Little Italy to places like Texas and California in search of greener pastures. This is because Little Italy is known for being a residential area with poorest Italian American in United States. Economic Segregation Based on immigration history, Italians were of lower economic and social status compared to their European counterparts like Spanish and Irish immigrants. Italians worked as farmers and laborers while British and Spanish immigrants owned farms and industries. Currently, economic segregation that existed during the immigration per iod is still conspicuous in Little Italy. Businesses owned by Italian Americans within the town are small and medium in sizes compared to those owned by people from other ethnic background. In terms of social status, Italian Americans in Little Italy live in cheap and affordable homesteads similar to those of Indian and Chinese Americans. This means that residents of Italian origin living in Little Italy still demonstrate a humble and economical living style. According to Vincenza (2008), there is a general notion that Italians were aware of their low economic power when compared to other European immigrants. In this case, their main intention of immigrating into the US was to work hard, accumulate wealth and return back to Italy. This explains why Italians in Little Italy does not prefer permanent homes and engage in casual occupation as a means of earning a living. Demographics As acknowledged earlier, Little Italy currently comprise of approximately 1200 Italian Americans. This i s contrary to the townââ¬â¢s population in 1910 when it reached a peak of approximately 10000 people from Italian ancestry. The reason for decline in population can be attributed to the fact that residents shift from one American state to another in search of better economic environments. In this case, Italian Americans who previously lived in Little Italy of lower Manhattan have moved to other places, leaving a
