What Is Art Essays - Aesthetics, Art, Emotion, Feeling,

What Is Art? What is Art? What a question! This very same topic has been on the minds of many great people for many years. Just what exactly is art? Art is a form of expression. It is beautiful, ugly, tasteful, distasteful, impressionistic, realistic...you get the point. Art is everywhere. It lives in the soul, mind, and even the heart. Art is an outlet for people to express themselves. Art is a way for the human mind to express itself. Even a loud, outgoing person has feelings that they do not feel comfortable sharing with people. These expressions often come out through their art. What is classified as art? Besides the obviouspaintings, drawings, architecture, etcArt can be dancing, singing, acting, etc. It can be pretty much anything that expresses an idea. Even something as common as speech is art. Everyone speaks with a different voice, and each voice is a piece of art. Art surrounds us. It is encountered so often that often we dont realize art when we see it. All too often we ignore art. We overlook the ideas and thoughts behind it. Anyone can look at a painting and say Wow! Thats beautiful! How many of us can actually stop and say Wow! Now I understand! Art is around to teach us. We can learn so much about ourselves and the world around us. Many times we create art without a conscious reason. We believe that we are just making a pretty picture. Usually we are expressing a subconscious idea. If take the time to actually analyze and critique our artwork we could possibly find out something about ourselves. Often, we use art to express some repressed feelings. Everyone has some feeling or thought that they wish to express but they are afraid. Art is seen as a window of opportunity for these people. They can express what has been on their mind without the worry of embarrassment. Even if a person does confront them about the meaning of the art, they can create a fictional story if they are still afraid. Even people who have feelings that are not repressed use art to express themselves. These people may be using it to sort their thoughts. Some people learn better visually than audibly. For these people, creating art will help their ideas become clearer because they can visually see something. Art is a very important part of modern and historical society. Without art we would not know as much about our history as we do. The surviving architecture, paintings, sculptures, etc. teach us about our past. It is from our past that we decide to change our future. Besides being of historical importance, art also has a modern impact on society. In todays society people are very worried about reputation. Art allows a person to express a less accepted idea without being punished socially. Art relieves a lot of tension in the world. It is a way for people to express their anger and other emotions. It is an outlet for emotions. It is based around an idea. All art has an idea behind it, but not all ideas are put into art. Arts Essays

Lung cancer Research Paper Example | Topics and Well Written Essays - 2000 words

Lung cancer - Research Paper Example In the United States, about 203,536 people are found to suffer from the disease regardless of sex with death of over 157, 000 victims in 2010 (www.cdc.gov/cancer/lung). Other countries have showed the same trend. In Europe, many countries showed high rate of deaths with Hungary in the top list having deaths that reached over a hundred victims a day. In Canada, lung cancer accounts for 30% death with cases of women on the rise. Far East Asia is not spared from the disease. Philippines alone have 43 daily cases of deaths. Taiwan and Japan share the same sentiment regarding the disease. China also has continual increase in numbers who die from the disease (Pastorino, 102). This scenario provides a picture that lung cancer is prevalent worldwide regardless of sex. Limiting the incidences of the lung cancer involves understanding the pathophysiology, causes, signs and symptoms, and diagnosis to be able to treat the disease at an earlier stage and to prevent high prevalence of its occurren ces. Pathophysiology The normal lung cell consist of two layers namely the columnar cells and basal cells. The columnar that contains mucus and covered with cilia makes up the surface layer. Basal cell which is the second layer contains the nuclei and basement membrane which in turn composes the glands, blood, blood vessels and lymphatic vessels. The initial response to a carcinogenic agent occurs in the tracheobronchial epithelium within the basal cells. Number of cells increase as it is triggered with the inhalation of any carcinogenic agents and referred to as carcinomas. This happens because oncogenes which make the body susceptible to cancer are activated. When a carcinogen enters the body, it binds with the DNA of the lung cells causing changes and differentiation of the cell. The structures of the cells are damaged which may cause abnormal growth. As the cell division continues to occur, the damaged DNA is also passed to the daughter cells and undergoes further mutations. Cel l growth becomes unstable and genetic changes accumulate. The pulmoepithelium in turn undergoes malignant transformation from normal epithelium to invasive carcinoma (Day, et al, p 558). Among the lung cancer type, adenocarcinoma is the most prevalent. However, when cancer cells metastasize, the tracheal and broncheal lymph nodes are the earliest to show signs of the spread to distant lymph nodes, organs, kidneys and brain. On the other hand, broncheoalveolar type is usually slow in nature than other types. Pleural effusion results as an effect of direct involvement of the pleura, obstruction of mediastinal lymphatics, throracic duct, pulmonary lymphatics, and atelectasis with pneumonitis and pulmonary embolus. Causes Lung cancer is believed to have many causes. It could be provoked with many carcinogens like tobacco smoke, radiations and viral infections. Although the disease is known to be a familial tendency, the risk depends with the exposure to carcinogenic risk factors. Almost all types of lung cancer are caused by tobacco smoke. About 90% of patients seeking medical help are found to be directly exposed to it. The most affected cells are the small squamous types. Tobacco contains multiple components however, not all of these may cause lung cancer. It is known that there are only a few that may really trigger the cells to undergo changes. Mazzone (p1) in his study identified N-nitrosamines and polycyclic aromatic hydrocarbons to be the two most carcinogens that are

Introduction - Essay Example The esterification equilibrium is displaced towards ester formation by use of an acid or large excess of alcohol. Additionally, the esterification reaction can be displaced by removal of water using a dehydrating agent e.g. sulphuric acid or distilling off the water. Esters can as well be prepared from alcohols with acid anhydrides and acyl halides. The reverse reaction of esterification is called hydrolysis. Esterification cannot be catalyzed by a base but hydrolysis can be catalyzed by OH- ions (Daintith 85). Spectroscopic techniques typically involve the interaction of some form of electromagnetic energy with molecules to generate a spectrum that maybe easily translated to disclose the incidence of distinctive groups and structural features. They are regularly used to authoritatively characterize the chemical, physical and specific structural attributes of an organic molecule. They are mainly efficient when analyzing a unadulterated compounds. They include: Infra-Red (IR) spectroscopy- a technique for observing distinctive bending and stretching frequencies of bonds. The spectra of regular organic functional groups have characteristic Infra-Red light absorption ranges that maybe used to identify functional groups in an unidentified organic compound. Additionally, the fingerprint region of an IR spectrum usually provides a distinctive pattern for an organic molecule. This pattern can be used for identifying an organic compound by comparing it with a known sample (Fox and James 209). Nucl ear Magnetic Resonance-a technique that identifies the nuclear spin flipping provoked in the radio frequency array of a molecule placed in a high magnetic field. Because 1H as well as 13C are magnetically vigorous nuclei. NMR spectroscopy may offer crucial structural information about organic molecules. Information acquired from H-NMR and C-NMR is corresponding. In H-NMR: the chemical shifts,

Managing a health and social cae orgainsation Essay

Managing a health and social cae orgainsation - Essay Example In this context, identifying appropriate management practices for the particular sector can be a challenging task. This paper presents a series of management theories that could be effectively used in the health and care industry. Reference is also made to the ethical and legal issues that tend to appear in the particular sector, at the level that these issues set limits to the freedom of the industry’s employees to take initiatives. It is proved that, like in all sectors, in the health and social care industry the use of appropriate management practices is quite necessary so that the industry’s organizations are able to face market challenges. In any case, before applying any management theory in one of the industry’s organizations it is necessary to take into consideration the ethical implications of the particular initiative. 2. Management and health and social care organizations 2.1 Models and theories of management relevant to a health and social care enviro nment Different views seem to exist in the literature in regard to the involvement of management theories in the health and social care industry. In general, the necessity of these theories for the industry’s organizations is not doubted. Still, oppositions have been developed as to which of existing management theories are most appropriate for the health and social care sector. ... asis is given on hierarchy, as it results to ‘different levels of responsibilities and rights among the members of the organization’ (Harris 2005, p.63). The bureaucratic theory is based on a series of rules, that need to be followed in all organizations that adopt the particular style of management: a) the hiring of an individual to a specific position is depended on his skills; the power of each employee as ‘a member of the organization is related to his position in the organizational hierarchy’ (Harris 2005, p.63); b) following the procedures is of critical importance; no employee has the right to take initiatives, unless they are within the context of the power given to the employee as member of the organization; (Harris 2005, p.63) the activities of individuals, as members of the organization, ‘are predictable’ (Harris 2005, p.63), meaning that there is a routine in regard to the tasks assigned to each individual; this routine cannot be cha nged unless it is ordered by the employer (Harris 2005, p.63). Another management theory that it is widely used in organizations operating in the healthcare sector is the institutional theory. The particular theory is based on the idea that organizations operate in environments that are characterized by ‘a series of myths, such as rules of professional conduct or ethical standards, to which organizations have to conform’ (Shortell and Kaluzny 1997, p.21). At this point, a key difference seems to exist between the common organizational environments, also characterized as ‘technical environments, and the institutional environments’ (Shortell and Kaluzny 1997, p.21). The former tend to press the organizations for continuously increasing their profits (Shortell and Kaluzny 1997, p.21). The latter require that the

Moths as Ecological Indicators

Moths as Ecological Indicators Results Articles from peer-reviewed journals, revolving around the topic of moths as ecological indicators, were collected and reviewed. The articles dealt with various studies conducted in different parts of the world and reveal the relationship between various anthropogenic impacts on ecosystem and change in moth diversity. To begin with, the studies carried out in the Australian rain forest, the moth assemblages were considered to be an effective indicator of the ecosystem. Light trap method was used to study the differences in diversity and richness of moths between the disturbed and undisturbed sites. As a result, a clear decrease was accounted in the number of moths of few of the studied species from less disturbed to more disturbed locations whereas few other species showed the exact opposite response. The reason behind this variation in the response could be the presence of the flora on which that particular species depends for its food. The literature shows that the moths present on the undisturbed site were mainly dependent on those large trees and the moths on the disturbed sites depend on herbaceous plants. Another study was carried out in the Eastern deciduous forests of North America where several moth families were studied as indicators of habitat disturbance. The selection of moth species was done on the basis of ease of sampling and the ease of identification. A comparative study was done in terms of accessing the moth communities of the prevailing forest edge and that of the interior habitat. Forest edges, recovering clear-cut stands, and small forest remnants were considered disturbed habitat types (Brown and Hutchings,1997; Usher and Keiller, 1998; Hamer and Hill, 2000;Summerville and Crist, 2003). There was a considerable decrease in the species richness in the interiors as compared to that of the edge. This shows that the selected species of moths can be considered as indicators of habitat disturbance. The phenomenon of global warming has devastation implications. The next study deals with the effects of climate change on moths in the forest ecosystem. The change in climate leads to an increase in temperature which in turn leads to termination of diapauses. It is a condition during which the development is on a standstill. This is considered to be a good example of indicator of climate change. Another article deals with the study carried out in Carinthian Alps in the years 2002 and 2004 which dealt with the study of population trends of moths as a result of restoration and the conservation and control sites were defined and monitored. It revealed that there was a decrease in the number of moths from 2002 to 2004 but the decline was more in conservation sites that control ones. This decline was attributed to the transformation of dense forest like habitats into open landscapes with the final outcome of semi natural grasslands with are rich in species. Therefore, the transformation from forest to open habitat is considered to be negative for moths. Moths proved to be an effective indicator to define the health of a forest ecosystem. The final article is based on the similar concepts and addresses the impacts of climate change on moth populations. Discussion and conclusions The study involved a literature review of several articles from peer-reviewed journals and was focused on the consideration of moths as ecological indicators. The main factors identified were: the effects of restoration, habitat changes, climate change and other anthropogenic activities on the moth population and the way in which they respond to it. Overall, the review revealed that the influence of the above mentioned factors on moth population has been well studied. However, there were many constrains in the studies. The studies were mainly limited to the local scale and local geographical and environmental conditions which can be considered as a limiting factor. The selected species of moths might be considered as an accurate indicator of ecosystem quality the articles reflected the same. The selection of such an indicator species to monitor the health of an ecosystem can be considered as a powerful tool for the analysis. It can be noted from the articles that climate shifts are the drivers of extinctions and the habitat contractions of moth species. It can also be inferred that the role of the host plant plays a major role, in the response of moths, towards ecological changes. As we saw in one of the articles, few species of moths showed higher richness in the disturbed sites because of the presence of the preferred plant. We can even compare the inferences of this article with the results we obtained at Agumbe Rainforest Research Station, where we studied the moth diversity over three different sites. By taking into consideration the results of the Shannon-Wiener index, the highest diversity was obtained in the forest site which was the least damaged as compared to the other two sites where the damage was comparatively higher. However, we cannot completely rely on the results because the study was too short. An inference can still be made out of it because the disturbance had negative impacts on moth diversity. Therefore, the decline in the moth population has been a matter of concern and these declines point towards the catastrophic loss of biodiversity because of anthropogenic environmental and habitat changes. On a concluding note, I would like to say that a future research based on the impacts of anthropogenic activities and climate change and its relation with moth population is necessary. An understanding has to be developed regarding the decrease in moth population and related conservative steps has to be taken. References S. Netherer, A. Schopf. 2010.

Growing With Style :: Writing Style Styles Essays

Growing With Style Defining writing style is somewhat like describing Big Foot. People study it, and talk about it, they try to enlighten others about it. But when it’s all said and done, you just rely on; â€Å"I’ll know it when I see it.† Style is not unique onto ourselves, but I think that we all, either as audience or as writer, have our own interpretation of style. For example, the University of Miami’s Philosophy and Literature Departments hold a Bad Writing Contest that gives mock prizes to the â€Å"worst published academic writing† that someone can find (Miami.edu). It is all in good fun and it is based solely on the opinions of the judges of the contest. The texts, Style: Toward Clarity and Grace by Williams and Elements of Style by Strunk and White teach about the importance of â€Å"good style.† Both books are quite different in their approach and the style in which it is presented. Strunk and White is short and sweet. Williams is lengthy and often times a tedious read. Both books are biased to their opinions; Williams is more instructional while Strunk and White almost sounds like a reprimand. However, both books offer up a wealth of knowledge and support. Both Williams and Strunk and White discuss the idea of clarity. Clarity is an important element of style because without it, you will have a lost or disinterested audience. Strunk and White state, â€Å"Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts†(23). Keeping this in mind will help a writer to stay on track. Instead of digressing on an unrelated topic, the writer can focus on a point and stick to it. Williams has two principles that help with managing and expressing a flow of ideas in a concise manner: 1. Usually, compress what you mean into the fewest words. 2. Don’t state what your reader can easily infer (115). A writer can achieve meaning compression by eliminating such things as redundant pairs (full and complete, true and accurate) and redundant modifiers (completely finish, past memories) (116). Some of these examples are so common in our speech that we can fail to see them as a problem in our prose.
