Challenges of Global Warming in Modern Society Essay

Challenges of Global Warming in Modern Society - Essay Example As green house gases increases in concentration in the atmosphere, so is more energy retained in the atmosphere and this increases the chances of global warming to increase. Some of the gases which constitutes green house gases include; carbon dioxide, methane, water vapour and fluorine gases. (Kim et al, 2010) These different greenhouse gases have different capabilities in heat-trapping. (environment.nationalgeographic.com, 2011) According to levy, global warming is evaluated by looking at the annual average temperatures as a function of time . The average temperatures are estimated from temperature recordings obtained from both the land and the sea. Land temperatures are obtained from weather stations while sea temperatures are estimated by assessing temperatures of the sea from a ship. The data obtained is first averaged over squares of one degree in latitude by one degree in longitude. Then, the averaged temperatures within the squares are summed to derive at the global average t emperatures. In attempting to compute global average temperatures, both the averaged temperature of the earth surface, sea and the combined temperature and averaged temperatures within lower earth surfaces also known as troposphere are employed. The information about the troposphere is gathered by use of weather balloons or micro wave sounding units mounted on atmosphere navigating satellites that have advantage of providing direct data. (Levy, 1999, p 370) Challenges of Global warming in Modern Society According to wbcsd.org, the changes in the earths climate system has catastrophic effects in the society and corporate world operates . The effects can have either physical, social or social impacts The impact s on the business world and in societies are very much uncertain in frequency and magnitude. The effect of global warming affects the business society in various ways. To begin with, high temperatures will affect the location, design efficiency and operation and marketing of bu siness products and services and its infrastructure.

Literary narrative - Essay Example My teacher was less pleased though; she said that I must try harder to trace the letters as they appeared. After some time, I was able to trace all these letters of the alphabet—I was even able to memorize two or three. The time of the day that was my most favorite was just after lunchtime, when it was time for all of us kids to sit on the mat and listen to our teacher sing the ABC song. I quite liked this song—I was even able to hum the tune in my head after not too long. To help us sing along, our teacher would point to each letter on the whiteboard as we spoke each letter. This was really good because I got to know each letter of the alphabet in order. It was, however, a struggle whenever the teacher covered up the alphabet chart and made us sing the ABC song off by heart. If the teacher displayed a card with only a single letter on it, I could rarely guess which letter it was. It helped whenever another kid whispered the correct answer in my ear, yet I was not able to remember many of the letters by myself. After I had finished with kindergarten, I entered the first grade of a local elementary school. It was here that my reading and writing skills really started to improve. The teacher of my first grade class was really kind to me and helped me whenever I was stuck with writing a particular letter. After a few short months, I was able to distinguish between every single letter of the alphabet. My writing was still a little messy, although it was improving with practice. One of the key things that aided my development was the use of alphabet posters in my bedroom. My parents decided that I could learn the alphabet better by having all the letters of the alphabet plastered on my walls. While I was trying to get to sleep, I was able to see the outline of each letter of the alphabet because of the light that was shining into my room. In my sleep, I was able

Is Adorno being elitist when he criticises the culture industry Essay

Is Adorno being elitist when he criticises the culture industry - Essay Example ts came from educated-in-elite-school-system Germans such as Schopenhauer, Martin Luther, Immanuel Kant, Karl Marx, Friedrich Nietzsche, Bach, Beethoven and Goethe. There was a point in time where the German elite formed the main part of the intelligentsia. â€Å"The Germans are literary people. The country is after all das Land der Dichter und Denker, the land of poets and thinkers.† (Wasser, 2006) To understand whether Theodore Adorno in his criticism of art, music and culture was guided by the moralist, egalitarian, capitalist or totalitarian stance, this paper will focus on Adorno’s biography and his contributions to the development of the culture industry as well as his critical views on music and popular culture. For the purpose of clarity and space, Adorno’s early works (1941-1941) will be used as reference to build the entire paper. In 1903 in Frankfurt, Germany, Theodore Adorno opened his eyes to an affluent and educated family. Both â€Å"his mother and sister were accomplished musicians and it was from them that he received his initial training and encouragement in his life-long love for music† (Jay, 1973). His Jewish roots ultimately became the deciding factor in his philosophical writings and thoughts, especially after Hitler’s totalitarian regime and the Nazi Holocaust swept over Germany with millions of Jews persecuted under it. During this time, Adorno was forced into exile and spent the next 16 years of his life in England and the US before returning to Germany to complete his doctorate in Philosophy from Frankfurt University. Adorno’s position on culture and the music industry has managed to establish key influences in the domain of media studies. His ideas about these industries were critical and in some cases, pessimistic. Adorno analyses the dynamics of the culture industry in the context of ‘standardization’ underlining it as a fundamental characteristic of pop music. He quotes himself: â€Å"A clear judgment concerning the

Fringe benefit plans Essay Example for Free

Fringe benefit plans Essay What, really, are fringe benefits? Fringe benefits are a significant share of a workers total compensation package, which has grown over time (Flynn, 2000). They are of two types: One type of fringe benefit is the spreading of an employee’s pay, which was earned while working, over periods when the employee does not work. The other type of fringe benefit includes all sorts of things which became substituted for money pay, which the employee may spend for things of his or her own choice. Instead of getting one’s entire money wage, the employee may get some of it in the form of specified goods or presumed services. All sorts of things become substituted for money pay. They range all the way from better toilet facilities in the plant to golf courses for members of the families of employees perhaps even help in building a church of some denomination in the community. It may be more company picnics, or a Christmas party, or insurance of one sort or another, or a pension for old age all sorts of things. Retirement pensions, even though all workers may be covered by a basic age-related state pension, the vast majority of firms operate an occupational pension scheme for their employees to which the firm contributes. In spite of the onus for pension provision shifting towards the individual in a number of countries, including the UK, company pension schemes remain a substantial and widespread fringe benefit. Other benefits include redundancy payments and discounts on company products and the use of company cars. Sometimes these fringe benefits are the result of employee pressure, either through the union or without any union. But often they are initiated by management; a company plan is put into effect. However they come about, fringe benefits of this type have one aspect in common. Smith (2003) has asserted that in each instance its cost comes out of the money due the employee as pay. Fringe benefits are not just a demand of last resort by men living in a society which already supplies them with almost everything they need. They satisfy some fundamental human needs which, but for conservatism on both sides of industry, would probably have become matters for the bargaining table long before now. Fringe benefit plans increase the benefits available to employees through provision of such benefits as better pensions, year-end bonuses, paid vacations, sick leave, and holidays and an air-conditioned working place, in addition to the employees’ basic salary. In some instances, profit-sharing agreements are also included, as well as store discount privileges of workers. At this stage, the desire for security and continuity of income may well have become as great, or greater, than the desire to raise income. Thus the social logic of fringe benefits in an advanced society. When it comes to health insurance and pensions, fringe benefits help compensate for myopia in an individuals consumption decisions. High marginal tax rates, for both firms and workers, encourage the use of fringe benefits. As workers have become better off in real terms this has increased their demand for fringe benefits. Fringe benefits conferred tax advantages on both workers and firms. In theory it was possible to determine the optimum combination of wages and fringe benefits in relation to the firms desire for profits. A substantial proportion of the average workers costs to his employer are in the form of fringe benefits. As far as private fringe benefits are concerned, large firms are able to obtain group discounts and larger numbers of employees ensure lower per-worker costs of administration. Often fringe benefits are taxed at relatively low rates, if at all. This creates strong incentives for the firm and its employees to increase the proportion of fringe benefits within total compensation. Further, taxation coverage is rather incomplete at the employee level owing to technical difficulties in taxing individual fringe benefits and because welfare income is relatively small. Fringe benefits also have an advantage to the employers not just because the benefits were tax deductible but also because they reduced turnover and thereby boosted productivity. Also, the use fringe benefits improved the overall morale of the employees. The social equation was working. WORKS CITED Flynn, B. (2000). Fringe Benefits. New Statesman, 129 (4499), 32. Smith, S.

Physics of the Heart

Physics of the Heart Electrocardiography Electrocardiography is the recording of the electrical of the heart by a non-invasive procedure. This is possible because the body is an electrical conductor, the ECG machine acts as a voltmeter and voltage time characteristics are measured by attaching electrodes to the patient`s skin. Electrical impulses created by the conducting tissue of the heart are picked up. The Sino Atrial Node (a small area of heart that triggers muscle contraction, acting as a pacemaker) is located at the top of the right atrium and sends a wave of electrical activity down the right atrium. Another wave of electrical activity is sent by the Atrioventricular node down the Bundle of His once the electrical activity by the SAN is received. There is a small delay before the AVN sends a wave of electrical activity, this is to allow the atria to empty fully before the ventricles contract. The ECG machine detects and amplifies electrical impulses (waves of depolarisation) initiated by the SAN. Each of the heart muscle cells in the body have a negative charge (at rest); this is called the membrane potential. The muscle cells have a negative charge because an active transport mechanism in the cell membrane maintains an excess of cations on the outside, and an excess of anions inside. This means there is a potential difference across the membrane. In the heart it is typically about 70 mV for atrial cells and 90 mV for ventricular cells. Decreasing the negative charge towards zero, via the flooding of cations (Na+ and Ca2+) into the cell, is called ‘depolarisation’ which ultimately causes the cell to contract. A healthy heart will have a distinctive wave of depolarisation that is: initiated by the SAN, spreads out through the atria, reaches the atrioventricular node and spreads all over the ventricles. The potential difference due to the heart`s electrical activity is measured by two electrodes (one positive and one negative). If the electrical impulse travels towards the positive electrode the result is a positive deflection. If the impulse travels way from the positive electrode the result is a negative deflection. Electrodes are typically placed on the arms, left leg and one or more over the heart. This helps to minimise signals from other muscle cells in the body. This can help a cardiologist to understand what is happening in different parts of the heart. The electrical impulses are translated into a waveform. The resulting ECG trace has a distinctive shape with sections that are labelled P, Q, R, S and T. Abnormalities in the shape of the wave are used to identify heart problems such as irregular contractions of the heart. The heart has a zero potential difference across it, the contraction of the atria produces a P wave (The PQ interval represents the delay to allow the ventricles to fill). The contraction of the ventricles then produces the QRS complex. Finally the T wave shows the relaxation of the ventricles. The period (R-R interval) is the time between adjacent peaks in the ECG trace. In a healthy person this varies by up to 10% between each heart beat. Heart rate is determined by averaging over multiple heart beats (Heart rate = 1/average period). The heart rate in beats per minute is equal to the frequency in hertz (Hz) x 60. The Physics of the Artificial Heart In artificial hearts (such as the one made by AbioCor), the electronic kit is implanted in the abdomen of the person receiving the transplant to monitor and regulate the pumping of the artificial electronic heart. Power is supplied from an external battery pack to components inside the patient, without penetrating the skin, using inductive electromagnetic coupling. A principal similar to this is used by transformers in the national grid. The internal battery can provide up to 40 minutes of power when disconnected from the external battery pack, for when the patient may want to have a shower for example. In transformers, an electrical current passes through a wire wound around a core, called the primary coil. Another wire is wound around the same core, this is called the secondary coil. If the two coils have the same number of turns around the core, it allows the primary coil to pass an exact copy of its electrical current to the secondary coil. These types of transformers are normally called ‘isolation transformers’. This allow two circuits to be electrically coupled, without the two circuits actually coming into direct physical contact. The image on the left shows a typical isolation transformer but the one used in this case is considerably smaller in size. The patient is constantly moving so it is quite difficult to keep the two coils aligned. This is important because the correct level of energy needs to be transferred via the wireless energy transfer system so that there is no excess transferred as heat to the surrounding tissue of the patient`s body; this could cause serious damage. Also the components need to be small enough to be carried around without too much discomfort. Furthermore, the artificial heart needs to be able to monitor the flow of blood to maintain its pumping action and make sure the correct amount of blood is being pumped. The rate of the pumping of the blood needs to be altered when the patient requires more or less oxygen, for example more oxygen is required during higher rates of respiration. Blood-flow monitors make use of ultrasound; ultrasound is used because the flow of blood can be monitored without having to be in contact with it. High-frequency sound waves are reflected off red blood cells coming out of the heart. The volume and speed of the blood can be measured using similar principles to those behind radar. The movement of these red blood cells, either towards or away from the transmitted waves, results in a frequency shift (due to the Doppler Effect) that can be measured. This data can help the system to determine the speed and direction of blood flow in the heart.

Critical Analysis on The Scream by Edvard Munch Essay example -- a cri

Critical Analysis on The Scream by Edvard Munch Edvard Munch was born on December 12 1863 in Loten Norway. He moved to Christiana, and spent most of his childhood there. Both his mother and his oldest sister suffered from tuberculosis and died before he reached the age of 14. At 18 he became more serious about his art and started attending art school. Edvard finally found a release for the pain he felt from his sister’s death. In 1886 he painted â€Å"The Sick Child†. The painting was so emotionally charged that it received a lot of criticism from the press and the public. However some of his artist colleagues began to recognize his talent. The same year another tragedy struck. His father died in November. Edvard received some scholarships that allowed him to spend the next few years in Paris. Although he would return to Norway during the summer, his style was that of a French Impressionist. In 1892 Munch submitted a series of paintings into a major Berlin art show. His exhibit was titled â€Å"The Frieze of Life†. This show caused an even larger uproar than his previous work. Edvard became a celebrity overnight and he painted such paintings as â€Å"the sick child† â€Å"the scream† and â€Å"vampire†, which showed his true emotion feelings. Edvard Munch had been through a lot of trauma, hurt and heartbreak in his life and his art work and painting helped him to expressive his feelings. I am going to be analysing and studing the Painting â€Å"The Scream†. Edvard Munch was an Impressionist painter. Expressionism is movement in the arts during the early part of the 20th century that emphasized subjective expression of the artist's inner experiences. This may ... ...e of the loneliest, scariest, and the most amazing place were we can escape to, and were no one else can know what you are thinking. I have seen how to symbolise certain things by colours and shapes and how to give a certain impression and mood. I can see how amazing dreams and nightmares are because they are not in this world, but they are only true portraits our ourselves and our lives so anything is possible and even our darkest and saddest feelings that we bury away inside us can show and come to life in our dreams. I have learnt to make a straightforward piece of art turn into an emotional and deep feeling that every person has different views and feeling about depending on their own lives. I can now see how this piece of artwork is truly individual, remarkable and unique as it shows that emotions of a broken man.
