George Wyche Essays (194 words) - Art Movements, Visual Arts, Arts

George Wyche Clement Greenberg Modernist Painting The core of this thesis is focusing on the philosopher Kant and how he sort of started the modernist movement. Later in the article the author compares the old masters to modernist painters today. The old masters fought to preserve the integrity of the picture plane in their paintings and images that they to avoid flatness in their paintings and to preserve the three dimensional and lifelikeness of it. Modernist painters today have left the three dimensional aspect of art to the sculptures. Just like the minimalist movement modernists have stripped down everything to the bare bones of shape and illusion. Francesca used abstract style to portray optical illusions and was somewhat recognized as impressionist or a neo impressionist. I know that all modernist paintings are not just colors on canvas with the occasional line but that is what it has turned into today. In my opinion I feel like modernist painting is very sexist at its core and somewhat against white males. I feel like I used to have modernist tendencies in my art work but it was never fully accepted and I chose to find another path to follow.

A Case For Slow Writing

A Case For Slow Writing A Case For Slow Writing A Case For Slow Writing By Guest Author Those of us with Italian backgrounds will know that you don’t make an authentic pasta sauce in an hour. It should be cooked slowly, the ingredients added one by one, at the right time. First the meats must be browned, next the onions, the herbs, spices and tomatoes incorporated. Then the mixture must simmer for two, three, four hours until it is a thick, mouthwatering sugo, the succulent meat falling off the bones. It’s good to cook slowly. But this is a writing blog, right? Yes. And it’s okay to write slowly too, blending words, sentences and paragraphs together, adding them to just the right part, in the proper sequence. Time spent writing can often look like this: You write a few lines, the thoughts are flowing. You’re in the zone. Then life rips you out after what seems like a mere five minutes. You go back to the computer, type another line or two, only to be summoned by the real world again. If this describes you, don’t worry - the story still brews while you attend to reality, the words sub-consciously simmering as you do what you need to. There are only two situations when you really must write fast: 1. When you have a contract or a time limit. Writers quickly learn to write with speed when they have a pressing deadline. Students know the perils of handing in late assignments. 2. When you write for a living. If writing is the only way you earn money, then your income is tied to your output. The rest of us are free to savour our writing if that’s what we want to do. Incidentally, J.K. Rowling and Stephen King are two of many authors who wrote novels at a snail’s pace. And there are lots of valid reasons why writing might take a long time. Maybe you: have a life. are just starting. don’t need the money. are a meticulous researcher. like looking for exactly the right words. need time to gather your thoughts and assemble the most salient. Or maybe you write simply because, fast or slow, it’s good for your soul. Amen. Whether you take a day or three to write a brief article, a month or four to produce a short story, a year or more to draft a novel, I’m here to say, it’s okay to take your time. While ever you are making progress and you haven’t given up, if writing makes you happy, there’s no reason to feel guilty about doing it slowly. Savour each word, each sentence, each paragraph.

Disparities in Pain Management in the Emergency Department Research Paper

Disparities in Pain Management in the Emergency Department - Research Paper Example The authors provide an overview from ancient civilizations to the modern theories. The modern theories include Melzack and Wall's Gate Control Theory of Pain. The knowledge in the article Theories of pain: From specificity to the gate, control can be used to understand the character of pain as well as its symptoms that reflect the significant aspects of the entire bodily suffering of the human body. The article provides more information on the manner in which pain functions including its structure and pathways. Acute Pain Management by Warfield CA and Kahn CH The stated research problem of article Acute Pain Management is that there is lack of professional and public awareness of pain management strategies. In addition, Warfield & Khan state that the significance of the problem is that medical professionals, as well as the public, should acquire knowledge on pain management in order to reduce the extent of postoperative pain. The purpose of the study is to investigate the situation o f acute pain management in the United States hospital. Additionally, the article was aimed at assessing the attitudes of adults in America in relation to postoperative pain control. A certain patient that had undergone through surgery believed that he was supposed to feel pain. This perception was contributed to by lack of adequate information on postoperative pain management. If the patient were aware that there are methods that can be used to reduce pain after surgery, he would have agreed to feel the pain.

Food management system Essay Example | Topics and Well Written Essays - 250 words

Food management system - Essay Example allergens are amino-acids in chemical compositions; they can be present in food in large concentration and yet escape detection during food processing process (Guidance on Allergen Management and Consumer Information, 2010). These allergic reactions are accompanied by extensive release of chemicals in the body that create an auto-immune cascade in the immune system on ingestion. There are certain identified food products that are prone to allergic contamination especially the fish, celery, cereals and other egg and mustard containing food items (Fish Allergy - What You Need to Know, 2014). However, these products need to be labelled according to current allergen labelling legislation in order to protect consumers from unsuitable immune reactions. The allergen management is essential in safe-guarding consumers from adverse reactions of allergy and involves the handling of instruments, utensils, and packaging the food products. This process is vital for identifying food allergens and the consequences of their intake by sensitive individuals. The management takes care of avoiding cross-contamination of food during preparation and processing by major food allergens (Allergen management and Labelling for pre-packed foods, 2014). This food management process is comprise of managing waste, cleaning procedures, and managing people movements to canteen and other visitors. The manufacturing process also requires the system of observing people movements as it can transmit allergens on their clothing or hands. Moreover, the handling activities of raw materials during harvesting and transport can transmit allergens and requires clear specifications of their suppliers. Further, the ingredients of the dish, as in this case is fish, ham and chicken pie with mustard, celery, white wine and cheese, are need to check of potential for allergy as certain proteins in fish and amylase in mustard can trigger immune reactions on intake (Fish Allergy - What You Need to Know, 2014).

Primark supplying consumers with ethically sourced garments Essay

Primark supplying consumers with ethically sourced garments - Essay Example Its main objective is to have a profitable as well as sustainable business (Goworek, 2011). Hence, the company always seeks growth opportunities in order to have a profitable growth within the organization. The company works closely with the suppliers as well as the factories which produces the goods for the company (BBC, 2015b). However, the role played by the Primark buyers is essential to support the ethical business practices. The company goes through a selection process in order to choose the new suppliers and factory in order to enhance their production process. The company while choosing new factories ensures regarding the fire safety measures and hires trained employees and also makes sure regarding the wages and benefits that they are supposed to receive (Goworek, 2011). Thus, the company focuses on the various ethical aspects that are to be followed in order to run a smooth business. The research has been carried out on various aspects of the business set up by Primark in the international markets. It comprises of a detailed analysis of the demand, supply as well as the price mechanism within the economy. A study is carried out on the overall demand of the customers for the products manufactured by the company. It also involves the number of customers purchasing the products of the company (Carrigan and De Pelsmacker, 2009). The research involves collecting secondary data related to the annual sales of the company and the total production of garments by the company. The data is mainly collected from authentic sources such as the newspaper articles from the well known news papers like Financial Times, Economist and also from the BBC news articles. The data on the annual sales of the company are also collected from the annual reports published by the company every year. The secondary data in turn helps to determine a conclusion regarding the overall

Impact of Social Relationships on Health

Impact of Social Relationships on Health There is considerable evidence that social relationships can influence health, but only limited evidence on the health effects of the personality characteristics that are thought to mold peoples social lives. We asked whether sociability predicts resistance to infectious disease and whether this relationship is attributable to the quality and quantity of social interactions and relationships. Three hundred thirty-four volunteers completed questionnaires assessing their sociability, social networks, and social supports, and six evening interviews assessing daily interactions. They were subsequently exposed to a virus that causes a common cold and monitored to see who developed verifiable illness. Increased sociability was associated in a linear fashion with a decreased probability of developing a cold. Although sociability was associated with more and higher-quality social interactions, it predicted disease susceptibility independently of these variables. The association between socia bility and disease was also independent of baseline immunity (virus-specific antibody), demographics, emotional styles, stress hormones, and health practices. Along with human population, the inequality in the distribution of global income has grown in recent decades (7). In 1992, 15% of people in the worlds richest countries enjoyed 79% of the worlds income (8). In every continent, in giant city systems, people increasingly come into direct contact with others who vary in culture, language, religion, values, ethnicity, and socially defined race and who share the same space for social, political, and economic activities (9). The resulting frictions are evident in all parts of the world. Ecologists and population biologists have long used the logistic model of population dynamics as a way to understand the cause and effect relationship between carrying capacity and population size (Wilson Bossert, 1971; Gotelli, 1998). As Malthus (Petersen, 1979) and Darwin (1859) understood, in the absence of limitations on resources, i.e., space and food, populations will grow exponentially. However, if resources are limited, the growth rate begins to decelerate well below the maximum population size that the environmental resources can support. Deceleration continues until a more or less equilibrium level is reached. This equilibrium occurs near the asymptote of environmental limits. When plotted, the resultant growth takes the form of a sigmoidal or S-shaped curve. Typically, in the laboratory and field. The second evolution refers to the industrial revolution, which took place mainly in the 18th century alongside the global agricultural revolution (Cohen, 1995). The third evolution is the advancement of public health and medicine which began in 1945. This led to a stark rise in the population as the development of vaccines and antibiotics increased life expectancy in the countries with access to them (Butler, 2004). The final evolution, per Cohen (1995), is the fertility evolution which began in the 18th century and has still not emerged in some developing countries (Cohen, 1995). Contraception and education for women have contributed to a fall in fertility rates among more developed countries (Butler, 2004). The end of the Second World War marked a fifth turning point in human population growth (Hibbard et al., 2006). No one had ever lived through a doubling of the population until after the Second World War and now, some of us have lived through a tripling of the population (Cohen, 2003). Today, the human population is distributed unevenly around the globe; with 60 percent residing in Asia, 16 percent in Africa, 10 percent in Europe, 9 percent in Latin America and the Caribbean and the remainder living in North America and Oceania (Cohen, 1995). Not only are we unevenly distributed, but so are our resources. In 2015, 795 million people do not have enough to eat (FAO, 2015). Simmons (2000) describes this phenomenon as a logistical distribution problem. We produce plenty of food on Earth, enough to feed everyone, yet millions starve to death every year (Simmons, 2000). Global life expectancy is expected to increase to 83 years by 2095 and by then, the human population will have at least doubled (UNDP, 2015). This will put further stress on our resources. If we struggle to feed everyone today, we will certainly struggle to feed a longer-living, doubled population in the future (UNEP-GEAS, 2012). How has carrying capacity been estimated? Many concepts have been used to try and decipher a limit to the human population. These include optimum population, carrying capacity and limits to growth (Van den Bergh Rietveld, 2004). What these concepts have in common is that they all acknowledge the basic requirements for a human being to survive; water, land, food and other resources from nature (Van den Bergh Rietveld, 2004). These resources have a limit and so it follows that the human population also has a limit (Van den Bergh Rietveld, 2004). Thomas Malthus theory about human population growth provided the basis for the concept of carrying capacity in relation to humans (Seidl Tisdell, 1999). The infamous theory was put forward in 1798. Malthus proposed that it was in built into the population curve for the population to run out of resources, causing a decline in the population by positive checks (e.g. disease, famine, war) or by preventative checks (e.g. marriage restrictions) (Butler, 2004). Malthus theory, though flawed, became so influential partly due to the attitude of Victorian England in the 18th century (Seidl Tisdell, 1999). During this time, disease and poverty was rampant among the lower classes as they moved into cities (Seidl Tisdell, 1999). The concept may have been relevant at Malthus time, but the human population has moved far beyond these limits now (Seidl Tisdell, 1999). Verhulst (1838) epitomized Malthus theory through the omnipresent logistic equation (Figure 2) (Lima Berrymand, 2011).

The Impact of Friends :: personal reflections

Every individual holds the key to their own future. We are told to follow our hearts and all your dreams for success will come true. We believe, you can make your future whatever you want it to be, no matter what you do. The truth is that success takes an enormous amount of determination and dedication. There are key things we need to look out for in order to be able to be successful. From your friends at school to how your carry yourself, it all makes a reputation for yourself. The successful people are the ones that understand how to balance it. This is why successful people are looked up to, and it all started out with the people they associated themselves with everyday from elementary school to now and even in the future. The question is, can friends affect your success? Your friends are constantly present in your life, more than your family. Most people, spend most of their time surrounded by friends instead of family this, is not always a bad thing but, has become normal. This is very true, especially for teenagers, who spent five days a week, 7 hours or more per day at school. Not including all the extra activities like sports, clubs and church that teenagers like myself are involved in. I believe people usually end up acting like the people they hang around with. â€Å"Friends play a big role in determining who you are and how you dress and talk and act†. (Compton 1 of 2 Peer pressure) My grandfather always used to say, â€Å"Show me your friends, and I’ll tell you who you are†. Drs. Davis, Jenkins and, Hunt also say this in their book, The Pact, â€Å"Friends play a big role in determining who you are and how you dress and talk and act†. (Compton 1 of 2 Peer pressure) . Although, it’s helpful to â⠂¬Å"Friends play a big role in determining who you are and how you dress and talk and act†. (Compton 1 of 2 Peer pressure) . When you are constantly surrounded by people with the same goals as you, and are going through the same problems it feels normal to involve yourself in what they are doing, because you feel like you are in the same â€Å"boat†. This can impact your success positively or negatively.

National Plain English Conference Essays

National Plain English Conference Essays National Plain English Conference Essay National Plain English Conference Essay Essay Topic: 9th Grade Dear Fellow Employees, After attending the National Plain English Conference in Washington, D.C. it came to my attention that some of the information obtained with regards to J.C. Penny’s could be highly useful within our own corporation.   There is no doubt that after reviewing J.C. Penny’s consumer information guide that J.C. Penny’s has had tremendous and great success.   The technique of using simpler and more easily read English by J.C. Penny’s has allowed them to reach markets with customers and internet consumers.   The main focus that J.C. Penny’s has had is to identify and answer questions by consumers utilizing some of the following techniques:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   A step-by-step approach that allows employees the benefit and assumption that consumers are not use to making decisions systematically and that they need guidance and attention.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Organizing information to make it easy to find by using illustrations, charts, and paragraphs.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Writing for a target audience of an 8th or 9th grade educational level.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   They realized that booklets can be an effective form of communication.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The booklets can be printed and distributed inexpensively and have shown a great response. The greater question is what they use and put into their booklets that allows them such a high success rate.   In order to generate and keep the interest of the public the following questions are asked in order to ensure the accuracy and usefulness and importance to the consumer:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Are the steps of the decision making process clear and concise throughout the booklet?  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Are they logically organized?  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Do the pages entice and invite the reader by using clear headlines, short paragraphs, charts, and meaningful illustrations?  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Is the plain English being used showing efforts and progress with the customers? I then questioned why they chose booklets.   Other options such as banners and signs that are posted in â€Å"proper† areas could be construed as having the same effectiveness.   So, why choose booklets?  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Consumers are familiar with booklets and pamphlets and will readily accept them.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Booklets are relatively inexpensive to develop and distribute.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Booklets can easily adapt to a wide array of topics and merchandise.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   They can be added in a variety of ways to retail settings and catalogs. The booklets (guides) seem to have high emphasis on the step-by-step approach.   This approach appears to pay off in the long run for the following reasons:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Consumer groups and educators purchase and use the guides in their programs, giving credence to the guide’s objectivity.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There has been overwhelmingly positive input from focus group sessions and consumer comments. In conclusion, I wish you all the best of luck in utilizing the information and techniques from J.C. Penny’s use of simple English.   Please remember your use of it does not have to be in the context of a booklet but can be used in any and all daily business documents and correspondence. Best Wishes, Anjanee S. Balkissoon

Galileo essays

Galileo essays Galileo Galilei was born on February 15, 1564, in Pisa, Italy. Galileo was the first of seven children of Vincenzio Galilei, a trader and Giula Ammannati, an upper-class woman who married below her class. When Galileo was a young boy, his father moved the family moved to Florence. Galileo moved into a nearby monastery with the intentions of becoming a monk, but he left the monastery when he was 15 because his father disapproved of his son becoming a monk. In November of 1581, Vincenzio Galilei had Galileo enrolled in the University of Pisa School of Medicine because he wanted his son to become a doctor to carry on the family fortune. Vincenzio thought that Galileo should be able to provide for the family when he died, and his sister would need a dowry soon. Galileo had other plans, and in early 1583 he began spending his time with the mathematics professors instead of the medical ones. When his father learned of this, he was furious and traveled 60 miles from Florence to Pisa just to confront his son with the knowledge that he had been "neglecting his studies." The grand duke's mathematician intervened and persuaded Vincenzio to allow Galileo to study mathematics on the condition that after one year, all of Galileo's support would be cut off and he was on his own. In the spring of 1585, Galileo skipped his final exams and left the university without a degree. He began finding work as a math tutor. In November of 1589, Galileo found a position as a professor of mathematics at the university of Pisa, the same one he had left without a degree four years before. Galileo was a brilliant teacher, but his radical ways of thinking and open criticism of Aristotle's teachings were not acceptable to the other professors at the university. They felt that he was too radical and that his teachings were not suitable. In 1592, his three-year contract was not renewed. 1n 1592, he landed a job teaching mathematics at the Univer...

Customer Service Essay Example | Topics and Well Written Essays - 750 words

Customer Service - Essay Example It is under the medical services industry and it is both a public and private health center as it houses both private and public wings. Sunrise Health Center has an in-patient bed capacity of sixty beds in four wards, with fifteen beds in each ward. The medical facility has fifteen employees with two in the senior management and two in junior management levels. Four employees are support staff where each is assigned to one ward. The other seven employees are medical staff who attend to patients and provide other medical services. The medical facility has a laboratory and a pharmacy which are manned by staff who are on a rotating work schedule. In-patients services are offered on a twenty four hour basis while the out-patient services are available during the normal working hours of 8.00am to 5.00pm from Monday to Saturdays. The out-patient section of the facility remains closed on Sundays and public holidays. The nearest hospital to Sunrise Health Center is St. Mary Mission Hospital which is twelve and a half miles away to the south. Sunrise Health Center refers all the complicated medical cases to this mission hospital and also relies on the referral hospital for supply of some drugs that are not readily available. St. Mary Mission Hospital also refers some of its patients to the medical facility for check-ups and other regular visits. This mostly happens for patients who live near Sunrise Health Center. Customer service in Sunrise Health Center seriously needs improvements. Some of the customer service issues identified are; lack of customer confidentiality, poor communication skills among the medical staffs, slow response to emergency medical cases, late opening and unavailability of drugs in the pharmacy. There have been two cases in the health center that were related to customer confidentiality. The first case involved a patient who developed breathing problems at work and was rushed to the health center by two of his

Mitochondrial DNA (mtDNA) characteristics and uses Assignment

Mitochondrial DNA (mtDNA) characteristics and uses - Assignment Example DNA sequence determination of the mDNA has been from many organisms including the extinct ones, and the comparison of the sequences outlines the mainstay of phylogenetics. The researchers have therefore been able to elucidate various evolutionary relationships within species. Additionally, the analysis of the relatedness of the populations among organisms has been ascertained and has become vital in the field of anthropology. The human mitochondrion DNA as an example, is commonly present per every cell except in sex cells as elucidated by Brown, George & Wilson, 1979, and is closely related to that of metazoans. The circular double-strand molecule of mDNA has about 15000 to 17000 base pairs and the nucleotide content differentiates the two strands. In animals, the transcribed strand produces molecules of polycistronic RNA. In replication process, the mDNA is replicated by the gamma complex of the enzyme DNA polymerase that is composed of 140 kDa of the catalytic section of the enzyme encoded by the gene POLG and two accessory subunits of 55 kDa encoded by POLG2 gene. During the process of embryogenesis, the mDNA replication is down because it is regulated from the oocyte that is fertilized through the embryo that is pre-implanted. At the stage of blastocyst, Anderson et al, 1981, further exemplifies that onset of the replication of the mDNA is specific to the trophectoderm cells. In contrast, the replication of mDNA is restricted by the inner cell mass cell until they receive signals making them differentiate to specific cell types. In the susceptibility concept, the mDNA does not necessarily accumulate many oxidative base damages than the nuclear DNA. As a result, some other types of the oxidative DNA damage are more efficiently repaired in the mitochondria than in the nucleus. The presence of proteins in the organelle further offers protection just as in the nuclear chromatin. The integrity of
