The Effects of Short Term and Long Term Stress on Physiological Processes

The Effects of Short Term and Long Term Stress on Physiological processes Stress can have many definitions, the NHS describes it as: stress is the feeling of being under too much mental or emotional pressure (2012) and some may describe it as when our demands outweigh our response. A stressor is anything that is likely to ‘set off’ your stress levels, when a person is feeling overwhelmed or they cannot cope with an event or situation (whether it be physical or psychological). During the 1920’s Walter Cannon began to recognise chain of rapidly occurring reactions in one’s body in response to acute stress.He described this reaction as the fight or flight response which will prepare the body to either fight or flee from a threatening situation (real or imaginary). Cannon discovered that during this response a series of physiological reactions will take place such as heart and respiratory rate will increase to allow for more oxygen to be pumped around the body to prepare the muscles for action. Blood pressure will increase as the blood vessels will constrict to enable to blood to move faster and more smoothly around the body.Pupils will dilate as they allow more light into the eye therefore allowing a boarder view of the situation. Our sympathetic nervous response to stress is our immediate response, this is an uncontrollable reflex to a stressful situation. Our hypothalamus send signals through our nerve cells to our pituitary gland to our adrenal glands, specifically our adrenal medulla. Here, the hormone adrenaline is pumped into the bloodstream causing the many physiological changes in our body. Also, noradrenaline will be release causing the non-essential systems to either shut down or slow down e.g. digestive system and immune system. As the adrenaline is coursing through our body it triggers the release of sugar from our temporary stores supplying energy around the body. Originally founded by Seyle in 1956, general adaptation syndr ome refers to the three stage reaction to stress and our adaptation to dealing and living with it. Stage one is the sympathetic nervous response: an immediate alarm reaction to a stress and our fight/slight response. Stage two is the stage of resistance (adaptation) where a prolong exposure to stress has occurredcausing our body to become adjusted to the stressor and the increased amount of hormones in our body (adrenaline/adrenocorticotropic). As a way of conserving energy and for optimum nutrient absorption a person may feel reduced desire for physical activity. The final stage is the exhaustion stage, as there has been an increased amount of corticosteroids in the body, the immune system will have become much weaker making a person much more susceptible to chronic illness/heart attacks/severe infection as our bodies are much less capable of an immune response.If a person has GAS then there body will be in the process of the parasympathetic nervous response, it differs to the symp athetic response as hypothalamus signals to the pituitary gland to release adrenocorticotropic hormone. This hormone will trigger corticosteroids into the blood from the adrenal cortex which suppresses the immune system and converts glycogen in muscles and the liver into sugar. In 1997, Marmot conducted a study into low job control and the risk of coronary heart disease. It was determined that low job control did increase the risk of heart disease.

Human imperfection Essay

There is a substantial debate among artists, critics and connoisseurs regarding the purpose of art. If views of painters like John Ruskin, writers like Robert Browning and art critic like Walter Pater are taken into account then it could be seen the perspective of the significance of art varies from person to person and school to school. Generally, the human race considers art as something that is pleasing to the eye or invokes certain emotions when viewed. And what many artists consider to be art is something which you can do and enjoy and in the end, produce something that gives a feeling of success. There are many different ways to express one using the concept called art. The most common style of art which most people think of when they think of art is the painting. The painting is usually just some form of paint media, whether oil or watercolor or whichever style it is, and the paint is then placed on some form of canvas. There are, however, literally hundreds of styles of art within the world. They range from the painting, which although never simple, isn’t necessarily the most complex way to express yourself. Art can even be considered in simple writing, usually in the form of poetry. The spoken word can have a more profound effect than physical art. A simple poem can invoke a range of emotions rather quickly. If a poem refers to someone who is close to the author, the author may feel overwhelmed when viewing their own artistic expression. But a painting can just as easily invoke the same feelings as a written piece of art. And a simple sketch has the chance of being just as profound. (Lamb, 243-245) In this context Ruskin’s point of view should be taken into account as he pointed out that the primary purpose of art is to evoke the value of god by showing the detrimental side of the human nature. He advocated this thesis with high degree of indulgence in his text ‘Modern Painters’. On the other hand Browning’s views of art were different from that of Ruskin but was not contrasting as he believed that perfection is what that all mattered in art. According to his views art should cover up the human imperfection and present a faultless, great and ideal image of the human being. His point of view on art was mostly presented through the characters Andrea del Sarto and Fra Lippo Lippi. It could be assumed that according to Browning art resembled whatever that was beautiful and faultless. In sharp contrast the point of view of Walter Pater completely rejects the previous two ideas. According to Walter Pater art should always be sensual and provoking. His idea of art completely ignores the aspects of spiritualities and sentiments along with any relation to emotion and theology. According to him any art that fails to evoke sensual feeling or satisfies the erotic feelings of the audience could well be labeled as failed art. In this context it would be relevant to quote Sir Kenneth Clark from his text ‘The Nude’. He mentioned that â€Å"no nude, however abstract, should fail to arouse in the spectator some vestige of erotic feeling, even though it be only finest shadow-and it if does no do so, it is bad art and false moral†. (Clark, 79) However, it can be stated that Art could be considered something as simple as an action someone has done for a cause or for somebody. If someone holds the door for somebody else, it could be their art to be generous and gentlemanly. Even acts of crime can be considered forms of art. In many thieving circles, the method of breaking and entering or robbing places is merely called the â€Å"Art of Theft†. Thus one can never really limit art to one thing. Rather, it is a wide arrangement of things. And one can never truly crack down and say that something is only artistic if it is of some particular kind of medium, because somebody else will disagree. It can be stated that Art is basically anything that anyone does which has a profound effect on somebody or something else. From a simple act of kindness to a masterpiece painting that took years out of somebody’s life. Some art can be considered more complex, and some art can be considered simpler in contrast. But, the fact of the matter is, in the eye of the beholder, art could be anything. So is it really possible for us to define what art is or can we really set any realistic guidelines as to what’s art and what isn’t art? It is always possible to create guidelines, but it is often considered an art-form in itself to break said guidelines. Similarly, the aesthetics of art could well be beyond the definition set by rigid guideline and logically thus the significance or purpose of art remains a relative concept. But defining what is aesthetic and what isn’t can also be quite an undertaking. Simply put, something that is aesthetically pleasing is something that appeals to the senses. For instance, flowers give a nice aesthetic sense of smell by offering their pleasant odors. A nicely painted picture can give off a nice aesthetic sight for somebody to enjoy. Often it is difficult to create something aesthetically pleasing, as there are many ways to easily offend peoples’ senses. For instance, if you wanted to create a painting to give off an aesthetic feeling of hope, you probably wouldn’t use an over abundance of dark colors. Dark colors are often used to show calmness or even more commonly, something sad and depressing. Also, when painting, if you use wider and more circular strokes with a lighter press on your brush, you’ll give off more depressing tones and colors. So, it would be more advisable to use lighter colors and more agile handling of the brush. Lighter colors often give off a feeling of warmth and happiness, which is something that you would like to be doing if you would like to create something hopeful. (King, 126) However, it can be stated that it doesn’t really matter whether or not we can define the significance of art, because art is just an expression. It is a method for human beings to get out their emotions and share them with the rest of the world. It helps to describe what cannot be spoken. A picture is worth a thousand words, but even those thousand words can yet again produce a thousand additional pictures. And in this method of thought, the significance of art has an infinite number of possibilities and an infinite number of ways to influence the lives of others. Thus the significance or the purpose of art lies in its spirituality, humane approach, sense of beauty and even sensuality all at the same time and there should not be any rigidity in this context.

International Accounting Standards Board - Essay Example The IASC Foundation is managed by 22 Trustees. The Trustees include highly experienced public and private sector professionals who belong to various parts of the world (IASB, n.d.). The IASC was established in 1973. The goal of IASB is "to provide the world's integrating capital markets with a common language for financial reporting" (IASB, 2008). Main objectives of the IASB, as defined by IASC Foundation constitution, include the following (IAS Plus, 2009): As shown above, IASB is appointed by IASC Foundation (which is appointed by and reports to the Monitoring Board). ISAC Foundation also appoints other advisory bodies that advise IASB on various activities. These include Standards Advisory Council, Working Groups for Major Agenda Projects, and International Financial Reporting Interpretations Committee. IASB develops IFRS using a standard 'due process'. IASC can review the process of standards development during any/ all step(s). The main steps of the process are described below (IASC Foundation, 2006. pp. 8-13): 1. Setting the agenda: The agenda is set with a view to address needs of most of the users of financial statements; mainly the investors. Some factors which are considered include the relevance and reliability of information that can be provided to users, availability or pre-existing guidance on the topic and possible convergence, resource constraints and the expected quality of potential standard. 2. 2. Project planning: At this stage, it is decided whether to do the project alone or as a joint project with other standard setting bodies. The project team is identified, assembled and finalized during this stage of the due process. 3. Development and publication of a discussion paper: Although not mandatory, but IASB usually publish a discussion paper to seek public comments and suggestions on the topic, agenda, and the targets. The comments are analyzed to determine if any improvement can be made. A discussion paper is developed after preliminary research on the topic and similar standards. 4. Development and publication of an exposure draft: Exposure draft development and publication is a mandatory step in the process. The exposure draft is developed after extensive research and details the proposal, agenda, and recommendations for the standard. Once developed, it is published to obtain comments. The comments are then analyzed to make required modification in the standard,

European Union Law Coursework - Essay Example The latter had been storing several chemical substances, including some of the chemical substances that had been specified in the Directive. In March 2007 Simon was hospitalized for mercury poisoning after eating vegetables from his garden. Mercury had been specified in the Directive. Investigations revealed that this mercury had leaked into Simon's garden from the adjacent Otis Chemicals' warehouse. Directives are the devices through which the European Council implements laws in the Member States of the European Union. Directives harmonise national laws with the European Union laws. The legal systems of the Member States are influenced significantly by the European Community, which governs the interests and rights of the Member States through its own organisations. There exists a unique and sovereign legal system that binds each Member State. This system was developed by means of the several Treaties, which created the EC legislation. One of the main pillars of the EU is the European Court of Justice or the ECJ. The ECJ had interpreted the nature and effect of Treaties, which is known as the doctrine of direct effect. It is a concept which enables aggrieved individuals to seek redressal in national courts if a Member State fails to implement the provision of a directive. The ECJ developed the notion of direct effect. Under this concept, individuals and organisations can use the provisions of the EC Law in a domestic court without having to wait for the Member State to satisfy an obligation which the Member State failed to execute. According to the ECJ, certain requirements have to be fulfilled for the provision of EC Law to gain Direct Effect. According to the notion of direct effect individuals can invoke community law to fulfil the required ratification for enforcement in their national courts. In other words, it empowers individuals to have a control similar to Article 226 EC, which bestows authority on the Commission to initiate proceedings against Member States for breaches. Direct effect permits each and every citizen of the Union to participate in the activities of the Union and it has brought the community into their lives. The legal aspects of direct effect have been established in Van Gend En Loos. The ECJ had held in this case that any individual of the Union can invoke Article 25 EC in order to restrict Member States that imposed additional customs duty on imports and exports and other charges that have equal effects. The Court also held that Article 25 EC was directly effective and individuals could challenge it in their national courts. The Court further held in its decision that individuals may have these rights conferred upon them directly under the provision of the various EU Treaties (Van Gend en Loos v Nederlandse Administratie der Belastingen). In Pubblico Ministerio v Tullio Ratti, criminal proceedings had been initiated, under the national law, against the applicant for the alleged infringement of Italian legislation, which was very stringent in the matter of packing solvents. Ratti resorted to the community directive's direct effect as his defence and the outcome was that a preliminary reference was made to the European Court of Justice. The ECJ placed an estoppel argument with the objective of directly enforcing the directive (Pubblico Ministero v. Tullio Ratti ). The ECJ held that if a directive had

They include; the act of building and nurturing a responsive relation between children and other people, the implementation of high-quality supportive environments, the use of social and emotional supports in as teaching strategies and lastly planning intense individualized interventions with a motive of promoting and intensifying support to children. When designing and maintaining learning centers a number of factors need consideration. Placement calls for a clear set boundary to let children concentrate on their play and learning without interruption. It is important to consider the numbers by making sure that there are adequate centers to accommodate all the children without congestion. In addition to this, there should be enough materials enabling children carry out their plans in social play. Art material, dramatic play props and toys should be availed in these centers. Lastly, images that include books reflecting the diversity of the community also play a significant role in a learning centre. While striving to support peer interaction, it will be of importance for me to consider making enough centers that would allow children the opportunity of interacting with others socially. Selecting a wide range of materials and activities relevant to the different needs of children will be of importance too. According

Fire Protection Hydraulics and Water Supply - Essay Example o different parts of a building and for local distribution to the miniature network of pipes in the building and they convey water to these respective regions in large quantities. They are more reliable when two or more primary feeder systems are extended by independent means from the supply source to the most important regions of the municipality (Brannigan & Corbett ,2008). Secondary feeders are water distribution systems that are made up of network of pipes that are quite smaller in size to the Primary feeder system. They strengthen the water distribution system and are surrounded by different sections of the primary feeder system. The Secondary feeder system helps in the full concentration of water and control the rate of fire flow that is required at a particular region in a building. It is necessary to give two water delivery directions to any spot; hence the secondary feeder system must be arranged in loops (Brannigan & Corbett ,2008). Distributors are the smallest class of the water distribution system as they consist of much smaller mains when compared to the primary and secondary feeder system. The distributor system is mainly used for specific fire hydrants and individual units of users(Brannigan & Corbett
