Organizational Behavior and HR in Sony Corporation Assignment

Organizational Behavior and HR in Sony Corporation - Assignment Example Kalyanaram and Gurumurthy (2008) offer that businesses that are the first to market in certain industries have a significant competitive advantage over competitors. Theory indicates that when buyers perceive a satisfactory product or achievement of effective customer service, risk averse customers often develop attachments to the pioneering product or brand; therefore they are unwilling to switch to new late movers’ products. Oftentimes, these buyers assess the late entrant against the first mover with adverse assessments in favour of the pioneer (Kalyanaram and Gurumurthy 2008). Sony was not able to launch innovative products (such as the LCD television) before competition, therefore the market had established brands with positive consumer sentiment about the brands that is difficult to undo for a late mover. The presence of competitive product offerings and new innovative products is what served as the first catalyst for change at the firm that required restructuring to meet and adapt to market needs more rapidly. Slocum and Lei (2005) reinforce the dangers of increased globalisation that make change a constant phenomenon, especially for businesses that operate in multiple business divisions and product categories, such as the conglomerate Sony. Industries are defined in theory as â€Å"ecosystems through which businesses compete for customers and are significantly inter-dependent based on changes in local or international markets† (Slocum and Lei 2005, p.35). Globalisation opens new markets for new competitive entrants into a market, breaking down the political barriers or improving supply networks that facilitate more rapid and cost-effective production with competition. Sony was witnessing many new market entrants offering unique products that were gaining attention and recognition from important revenue-building markets, essentially shortening the product life cycle of many of its previously-profitable products such as the PlayStation gaming console and older cathode ray tube television sets. Sony was now facing competition that sustained the resources and talents needed to produce innovative products. This challenge of competitive innovations was built through increased globalisation, thus Sony could no longer sustain the growth of existing Sony products, forcing the business to be more adaptable and flexible in providing similar competitive products. Consumer markets were favouring competitive products which continued to erode market share from Sony, making change driven by competitive product introductions forcing the need for continuous change practices to be developed in order to remain relevant in its technology markets. As market circumstances continue to evolve, contingency theory states that the organisation’s internal structure must adapt in order to remain competitively relevant (Buchanan and Huczynski 2010). It was not until the new CEO Howard Stringer joined Sony that the business became aware that continuous change in the external market was causing a need for rapid internal restructuring in order to adapt properly to market conditions and more prevalent competitive practices in manufacturing and marketing. Sony relied heavily on its electronics division to generate profitability, therefore the business was forced to centralise decision-making so that the electronics division maintained authority over key areas of business. The business could no longer respond quickly enough to meet competitive actions in the market,

Endangered Snow Leopard Research Paper Example | Topics and Well Written Essays - 1500 words

Endangered Snow Leopard - Research Paper Example Global snow leopards’ effective population size is estimated to be about 50 percent of the total population which implies that there are 2,040-3,295 snow leopards in the world (qtd. in Jackson et al.) This paper studies the factors contributing to the threats of snow leopards’ extinction; its impact; and suggested solutions. Snow leopard is found in the high mountains of Central Asia with major regions that include: Altai, Pamir, Hindu Kush, Tian Shan, Kun Lun, Karakorum, and Himalayan ranges (McCarthy et al.).Ecological regions are defined to be Altai-Sayan, Trans-Altai Alashan, Tian Shan, Pamir, Gobi, Hindu-Kush, Himalayas, Karakorum, Tibetan Plateau, and Hengduan Mountains (Williams, 2008 qtd. in Jackson et al.) 2. Causes of being endangered Major factors which contribute to the threats of snow leopards include: decreasing prey base; illegal trade; encounter with local people; lacking conservation activities; inadequate policy and implementation; and lack of awarenes s among people (Jackson et al.).The Snow Leopard Survival Strategy determined major threats to the specie which can be categorized as: habitat and prey; direct killing; policy and awareness; and other issues (McCarthy et al. 31). 2.1 Habitat and Prey Threats   2.1.1.Habitat Fragmentation and Degradation   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Snow leopards utilize several habitat types on marginal basis; however, they have strong association with high alpine tundra which is a very fragile ecosystem itself. Such narrow scale of habitat expose snow leopard to the vulnerability of habitat change in particular. Changes in the habitat over most of snow leopard range do not comply with the common perception of habitat degradation and fragmentation. Construction of roads, large scale natural resource extraction, and urbanization takes place within the snow leopard range; however, its incidence is rare due to remoteness and inaccessibility. Most observed form of habitat alteration is comparatively s ubtle but equally destructive and happens in the form of livestock and their owners’ interference (McCarthy et al. 29).   2.1.2. Natural Prey Reduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Snow leopard’s habitat mountain ungulates are hunted, either illegally or without any regulation. They are hunted by locals either for meat or as a symbol of their victory; meat is also used to serve for honored guest or on special holidays. Moreover, wild meat is greatly appreciated due to its medicinal value. Sometimes, illegal hunting occurs as a result of commercial activity. There is nearly absence of legal hunting by locals which disenfranchises them and makes it hard to comply with the law. Legal harvesting exceeds the allowed area which results in the reduction of snow leopard food resources (McCarthy et al. 30). 2.1.3. Legal Hunting of Natural Prey Sheep and goats trophy hunting is quite prevalent and a lucrative business in most of snow leopard rage-states. It generates wealth fo r private and state hunting reserves. However, they can play a vital role in community base conservation by providing local people with the incentives to protect wild life and its habitat. These hunts are not properly manages and lead to either medium-term social instability or long-term genetic issues. Major conflict in interest is created by the major part of income is generated by trophy hunting. Ungulate stock is reduced limiting the surviving ability of snow leopard and other carnivores. Other declining prey species

The Photoelectric Effect

The Photoelectric Effect Assessment Task Topic: The Photoelectric Effect 1. Introduction The photoelectric effect is the name given to the phenomenon whereby electrons are emitted from a metal when exposed to electromagnetic radiation of the appropriate frequency. It was first discovered by Heinrich Hertz in 1887, but remained a conundrum to many scientists who sought to explain it, as it clearly contradicted the accepted principles of classical physics such as James Clerk Maxwells Theory of Electromagnetic Waves. This phenomenon, unable to be explained by the wave model of light, was finally explained by Albert Einstein in 1905 with the inception of his Quantum Theory, a concept that would completely revolutionise scientific thought. The photoelectric effect has played and continues to play an important role in mankinds scientific development. 2. Discovery of the Photoelectric Effect: Hertz The original observation of the photoelectric effect can be traced back to the German scientist Heinrich Hertz. In 1887, in an attempt to generate and detect electromagnetic radiation, Hertz created a rapidly-oscillating electric field with a high voltage induction coil to cause a spark discharge between two spherical brass electrodes. He observed that when a small length of copper wire with brass spheres attached on either end was bent into a loop, leaving a small gap between the spheres, and held near the sparking induction coil, a spark would jump across the gap at the same time when the brass electrodes in the induction loop sparked. This induced spark occurred despite the copper loop not being connected to any electrical current source. Thus Hertz came to the conclusion that the copper loop was a detector of the electromagnetic waves propagated by the transmitting loop. This successful experiment was followed up by a series of others, through which Hertz demonstrated that these electromagnetic waves could be reflected from a metal mirror, and refracted as they passed through a prism made from pitch, thus proving that these waves behaved similarly to light waves. He also proved these waves were polarised. Through the course of his investigations, he discovered a mysterious phenomenon: I occasionally enclosed the spark B[the detector spark]in a dark case so as to more easily make the observations; and in so doing I observed that the maximum spark-length became decidedly smaller in the case than it was before. On removing in succession the various parts of the case, it was seen that the only portion of it which exercised this prejudicial effect was that which screened the spark B from the spark A[the transmitter spark]. The partition on that side exhibited this effect, not only when it was in the immediate neighbourhood of the spark B, but also when it was interposed at greater distances from B between A and B. A phenomenon so remarkable called for closer investigation. Upon shielding the detecting loop with glass, the intensity of the spark produced was reduced. However, when a quartz shield (a substance that allows UV rays to pass) was applied, there was no drop in the spark intensity. He then used a quartz prism to separate the light from the transmitter spark into its various components, discovering that the wavelength which made the detector spark more powerful was in the ultraviolet range. Unable to explain this phenomenon, Hertz concluded his series of investigations in 1887, declaring that: †¦ I confine myself at present to communicating the results obtained, without attempting any theory respecting the manner in which the observed phenomena are brought about. 3. Further Investigations: Hallwachs, Thomson, von Lenard After learning of Hertzs experiments, another German scientist, Wilhelm Hallwachs, devised a much simpler investigation to demonstrate the photoelectric effect. In his own words: In a recent publication Hertz has described investigations on the dependence of the maximum length of an induction spark on the radiation received by it from another induction spark. He proved that the phenomenon observed is an action of the ultraviolet light. No further light on the nature of the phenomenon could be obtained, because of the complicated conditions of the research in which it appeared. I have endeavored to obtain related phenomena which would occur under simpler conditions, in order to make the explanation of the phenomena easier. Success was obtained by investigating the action of the electric light on electrically charged bodies. By placing a zinc plate atop an insulating stand and wiring it to a negatively-charged gold leaf electroscope, he observed a slow loss of charge from the electroscope. However, when he exposed the zinc plate to ultraviolet light from an arc lamp or from burning magnesium, the discharge occurred much quicker. Conversely, a positively-charged electroscope resulted in no fast leakage of charge. In 1899, British scientist J.J. Thomson finally identified that the light caused the metal surface to emit electrons. He enclosed the metal in an evacuated tube before exposing it to radiation, showing the electrons to be the same particles emitted in cathode ray tubes. Three years later, German physicist Philipp von Lenard, who had worked with Hertz earlier in Bonn, conducted a series of experiments in which he used a bright carbon arc light to examine how the energy of the emitted electrons varied with the lights intensity (see Figure 2). By using a vacuum tube, he showed that when electrons emitted by the metal plate upon exposure to light hit another plate, the collector, a small measurable current was produced. By charging the collector negatively so as to repel the electrons, von Lenard discovered that a minimum voltage existed, Vstop, so that only electrons with a certain energy threshold could reach the collector and thus generate a current. He found that while increasing light intensity caused more electrons to be emitted (as can be gathered from an observed increase in current), it did not affect the amount of energy carried by each electron, as the stopping voltage was constant. On the other hand, increasing the frequency of the light led to an augmentation in the electrons kinetic energy, thus finding that for a particular frequency of light, the kinetic energy of the electrons remained constant. Von Lenard also showed that if the frequency was lowered beyond a certain threshold, no current was produced, regardless of the intensity of the light. However, like the scientists preceding him, he was unable to account for these phenomena. 4. Inadequacy of Classical Physics Explanations The phenomenon observed during the photoelectric effect was in contradiction to classical theory explanations such as Maxwells Theory of Electromagnetic Waves which was then commonly accepted by scientists. According to such rules of classical physics, for an electron to gain enough energy to be liberated from the metal, the metal surface would have to be exposed to the light waves for a period of time. However, as observed in experiments of the photoelectric effect, the electrons were freed instantly. The Wave Theory maintains that increasing the intensity of a beam of light also increases the amplitude of the oscillating electric field vector E, thus the amount of electrons emitted should be proportional to the intensity of the light. However, according to the observations made, the current flow was independent of light intensity, yet varied according to the frequency of the light, and was non-existent when the frequency decreased beyond a certain level, regardless of the intensity. Von Lenards experiment confirmed the existence of a threshold frequency in the photoelectric effect, another phenomenon unable to be explained with a classical physics approach. Thus the belief in light being completely wavelike in nature was incompatible with the experimental observations of the photoelectric effect. 5. Black Body Radiation and Plancks Hypothesis A black body cavity can be defined as a perfect cavity that absorbs all radiation that falls onto it and then perfectly radiates all energy absorbed until it is at equilibrium with its surroundings. The intensity of various wavelengths emitted by the black body changes according to its temperature, forming black body radiation curves (see diagram on right). Experimental data showed that the intensity of radiation emitted increased with decreasing wavelength, until a definite peak is reached, after which lower wavelengths of radiation are emitted at lower intensities. Yet, according to the classical wave theory of light, as the wavelength of the radiation emitted shortened, the intensity should increase, thus as the wavelength tends to zero, intensity would approach infinity. However, this would be a gross violation of the principle of conservation of energy. Hence it remained an inexplicable conundrum for scientists for a long time, who gave this effect the name ultraviolet catastrophe. In 1900, German scientist Max Planck came up with a revolutionary explanation for this phenomenon. He made the assumption that the radiant energy may be treated statistically not as continuous waves but rather as discrete packets of energy, each of which he called a quantum. Based on this radical assumption of light as particles, he formulated a mathematical equation by which this phenomenon could be exemplified. He proposed this relation that calculated the energy of a quantum for radiation of a certain frequency: E= hf,Ebeing the energy in joules, fthe frequency in Hertz, and ha small constant (6.626 x 10-34Js) now known as Plancks constant. Figure 4 is a graph of experimental results that confirms Plancks equation, with the gradient corresponding to h. He proposed that any quanta of a particular frequency (and thus wavelength) would carry the same amount of energy. However, he did not attribute any physical significance to this postulation, merely perceiving it as a mathematical t rick by which the corresponding answer could be obtained. 6. Quantum Theory: Einsteins Explanation Due to the inadequacies of classical physics in explaining the photoelectric effect, in 1905 Albert Einstein further developed upon Plancks hypothesis to come up with a new ground-breaking theory to explain the photoelectric effect. He proposed that light was made up not of continuous waves but rather of discrete bundles of energy which he termed photons. He wrote in the renowned journal Annalen der Physik: It seems to me that the observations on black-body radiation, photoluminescence, the production of cathode rays by ultraviolet light and other phenomena involving the emission or conversion of light can be better understood on the assumption that the energy of light is distributed discontinuously in space. According to the assumption considered here, when a light ray starting from a point is propagated, the energy is not continuously distributed over an ever increasing volume, but it consists of a finite number of energy quanta, localised in space, which move without being divided and which can be absorbed or emitted only as a whole. Einstein used Plancks equation that each photon had an energy E=hf, and proposed that light intensity was proportional to the number of photons. The higher the frequency of the electromagnetic radiation, the greater the energy carried by its photons. Einstein provided a comprehensive explanation for the photoelectric effect. When an electron is liberated from the metal surface, the energy in the light photons must be great enough to overcome the forces that bind the electrons to the surface. This minimum energy required to liberate an electron from a metal surface is known as the work function, represented by the symbol  ¢, and is dependent solely on the material of the metal. The corresponding minimum frequency required for the photons to contain the required energy is called the threshold frequency (f0). If the energy of the photon is greater than the work function of the metal (i.e. E> hf0), than the difference in their energy levels will provide the kinetic energy for the photoelectrons (electrons released from interaction with a photon), allowing them to travel and thus generate an electric current. Einsteins quantum theory explains the existence of a threshold frequency for the light below which no electrons would be emitted from the metal, an experimental observation that had puzzled scientists up to that time. Einstein established that when different metal surfaces are illuminated with monochromatic light, photoelectrons are emitted by the metal surface. The magnitude of the forces by which electrons are held varies with different metals. Thus the work functions of each different metal are also varied. Below is a table of the work functions of various metals. Figure 6:Work Functions for Various Metals Source: Nave, CR. HyperPhysics: Photoelectric Effect According to Einsteins theory a single photon collides with an electron in the metal, transferring all its energy to the electron, thus liberating the (photoelectron from the metal surface. This concept successfully explained the instantaneity of the electron emission upon light exposure, another phenomenon that classical wave theory was unable to account for. In Einsteins own words, According to the idea that the incident light consists of energy quanta†¦ one can picture the production of cathode rays by light as follows. Energy quanta penetrate into a surface layer of the body, and their energy is at least partly transformed into electron kinetic energy. The simplest picture is that a light quantum transfers all of its energy to a single electron; we shall assume that that happens. We must, however, not exclude the possibility that electrons only receive part of the energy from light quanta. An electron obtaining kinetic energy inside the body will have lost part of its kinetic energy when it has reached the surface. Moreover, we must assume that each electron on leaving the body must produce work P, which is characteristic for the body. Electrons which are excited at the surface and at right angles to it will leave the body with the greatest normal velocity. Einstein formulated an equation, known as Einsteins Photoelectric Equation, to provide a quantitative explanation for the photoelectric effect: E= hf=  ¢+ Ek with Ebeing the energy of the photon (thus E= hffrom Plancks hypothesis), ¢the work function of the particular metal ( ¢= hf0), and Ekthe photoelectrons kinetic energy (in Joules or electron volts). Einsteins theory also explains the stopping voltage in the photoelectric effect, which von Lenard had discovered earlier. This voltage is a good measure of the kinetic energy of the photoelectrons. It can be demonstrated (see figure 7) by introducing a variable electric potential difference to make the anode negative, thus generating a repelling force against the photoelectrons emitted from the cathode. As this opposing voltage is increased, it will arrive at a point where there is no current flowing in the external circuit as the photoelectrons kinetic energy is not enough to overcome the voltage. This stopping potential equals the maximum kinetic energy of the electrons at the cathode, as it is just enough to stop any electron from reaching the anode. Thus EK max= -qV0, where EK maxis the maximum kinetic energy of the electron in joules, V0the magnitude of the stopping potential in volts, and q the charge of the electron (-1.60 x 10-19C). As the unit of the joule is too large to be used effectively for atomic systems, the electron volt (eV) is employed instead, with 1 eV = 1.60 x 10-19J. Thus the maximum kinetic energy of a photoelectron can be experimentally obtained from the stopping voltage. Radiation with higher frequencies will result in higher stopping voltages, and vice versa. With his theory of the quantisation of light, Einstein was able to derive Plancks formula and account directly for such hitherto inexplicable phenomena as the photoelectric effect and black-body radiation. His work overturned the previously accepted, but now proven flawed, wave theory of light, heralding a new era with the concept of wave-particle duality, in which light can be seen both as waves and as particles (quanta). It was for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect that Einstein was awarded the Nobel Prize for Physics in 1921. Another notable scientist, the American Robert Millikan, expressed grave doubts about Einsteins quantum theory and set out to experimentally prove him wrong. However, after a decade of thorough scientific investigations, Millikans results confirmed Einsteins theory in every aspect. He was even able to measure Plancks constant to within 0.5% accuracy. These travails earned Millikan the Nobel Prize in 1923 and further validated Einsteins quantum theory in explaining the photoelectric effect. 7. Practical Applications of the Photoelectric Effect The principle of the photoelectric effect is utilised in many domains. One significant application of the photoelectric effect is the solar cell. This is a device that converts electromagnetic radiation from sunlight into electrical energy. It is generally made up of a series of metallic plates facing the sun, emitting photoelectrons when struck by sunlight. These electrons then flow through an external circuit, thus generating electrical power. Another practical application is the photomultiplier tube (PMT). When light is shone onto a photosensitive cathode, electrons are emitted, and subsequently accelerated towards a second cathode. This produces more electrons, and is repeated for a number of cathodes, resulting in the multiplication of the number of electrons initially emitted by a factor of a million, to be detected as a current pulse at the final electrode. Thus PMTs are extremely sensitive light detectors, used in scientific applications that require high levels of accuracy, such as emission spectroscopy experiments. Phototubes also operate on the principle of the photoelectric effect. The electrical characteristics of these devices are dependent on the light that they are exposed to. Thus the current produced from a phototube may be used to operate sensor-based appliances such as automatic doors, sensor taps, alarm systems and light-activated counters. 8. Conclusion The photoelectric effect has undeniably played a significant role in the development of modern physics ever since its discovery. It has revolutionised mankinds understanding of the nature of light, its wave-particle duality. It was in the pursuit of an explanation for this phenomenon that Einstein made what was an important great leap forward in the world of science 3/4his conception of quantum theory. In fact the photoelectric effect and the problem of the ultraviolet catastrophe in black-body radiation formed the two experimental foundations upon which quantum theory was built. Thus the experiments conducted on the photoelectric effect can be considered among the most significant in the history of physics. Three distinguished physicists received the Nobel Prize in part for their work on the photoelectric effect: Max Planck in 1918, Albert Einstein in 1921 and Robert Millikan in 1923. The observations of the photoelectric effect and its subsequent explanations by Einstein can be regarded as directly responsible for the birth of modern physics.

America Must Join the International Community Essay -- Politics Politi

For the past century, Americans have viewed the United States as standing as a symbol of strength, freedom, and prosperity. Recently, however, this symbol of higher society has been directly attacked by those who strongly disagree with the values projected by the United States. This is one of the first times that the stance of America has even been questioned. The answer to this is scattered in many places and divided into two different categories-- where the people of America stand as citizens of a country under attack, and were America as a nation stands in global respects. The people of America have been taught and expect to have the right to trust their government. The Constitution and governing institutions are set to serve the people and their rights. However, in past situations of war, American citizens have been deceived and blatantly lied to. In 1964, President Lyndon B Johnson officially declared war on Vietnam. The action that directly influenced this declaration is known as the Tonkin Gulf Incident. A US destroyer was attacked and sunk in the international waters of the Tonkin Gulf. President Johnson conveniently left out information to Congress and American citizens and called this attack unprovoked and used it as an excuse to launch full-scale mobilization. He eagerly exploited symbolism and patriotism while deceiving the American public as well as Congress. The government continued to hide details of how devastating the progress and causalities were throughout the duration of the war. Most Americans today still wonder what went on during Op eration Desert Storm during the late 1980's and are mostly let in the dark about incidents in Kosovo. It is hard to leave your immediate future in the hands of a government t... ... back us militarily, and now it is America's turn to recognize these nations as economic and cultural equals. The United States has always been the first nation to assist others when times of need. Never before have these favors been asked for reciprocation. This constant requirement to help others in need has also helped Americans to build egos and look upon the country as indestructible. Having to ask other nations for support is a humbling experience for the United States and will be an important agent in assisting the incorporation of America into the global network. As devastating as these past events have been to the confidence of the American people, perhaps the catastrophe can be used in a positive way. This attack was an indirect call on Americans to open their eyes and look toward the rest of the globe and open their arms to the international community.

The story began from two enterprises. The company Royal –biscuit, would like to merge Edeling, a company from Germany. Brighton, CEO of Royal-biscuit, had coordinated with Wallach for many times. When they decide to merge together, they should have known that both of their cultures are quite incompatible which might result in severe conflict. In this case, we can see that most of the difficulties are about cross-culture difference. The culture of Royal-Biscuit emphasizes â€Å"Active†, â€Å"Ambitious†, and â€Å"Fast-training†, and that’s the reason why it changed food industry in UK within 10 years. However, Edeling is a family owned business with 120-year history, and quite popular in Germany. Employee in Royal-Biscuit were afraid that they might make things slowly down if everything are well-prepared and step by step, while employee in Edeling were afraid that they didn’t respect their history at all, just eager to succeed in short term. Such situation not only happened in internal management, but also happened in human resource, like recruitment for talented. Brighton wanted to integrate two companies ASAP, so that they train they staff to own leadership by â€Å"Learning and doing†. They put them in the managerial position directly. On the other hand, Edeling has a successful business model due to their system and operation. They cultivate their leader by sending them to college of commerce and doing work from basic level. Not only culture difference in both company, but also about â€Å"Nation difference†.

Yet I consider myself fortunate to have met such a special person †¦ a person that we care so much about †¦ that it makes saying goodbye to them hard! As we say goodbye, we remind ourselves that farewells are not forever, nor are they the end. They are simply words to say that we will miss you dearly and that we will remember you fondly. I still remember the day when I first met my seniors and to tell the truth I was really terrified by those sweet funny things which they made me and my class fellows do. But later we all realized that it was just to increase our confidence level and to decrease the communication gap among us. And I hope that this is quite an example to demonstrate their well wishes for us. Although we may be separated by time and distance in the interim, nothing will diminish the important role that you have and always will play in our lives. We wish you happy adventures, fantastic new friendships, amazing experiences and the journey of a lifetime. Most of our life is a series of images. They pass us by like towns on the highway. But sometimes, a moment stuns us as it happens. And we know that this instant is more than a fleeting image. We know that this moment†¦ every part of it†¦ we will live on forever. In the end I would like to say that where ever you go you will remain closer to our hearts. And May you conquer new fronts in life. May God bless you with a happy successful life and I..

Life is series of events, both good and bad. No matter how deft your organizational skills, there will always be life influencing factors over which you may have no control. As you embark on this new stage of life, you will be able to rise to the occassion because of the values our school has taught you. On such occassions think of principles our teachers have instilled in you and make us proud. â€Å"Change indeed is painful, yet over needfull†, said Thomas Carlyle. We are going to miss you very much. We pray that God guide you and guard you, as you undertake this new and exciting journey of lifem in 11th science. A very good evening to all the respected dignitaries, teachers, my lovely seniors and friends, I Yashodhar of M. E VI sem am humbled and honored to have the opportunity to bid you farewell from your juniors. On behalf of my class, I want to congratulate every one of you on your successes at Global Institute Of Technology ; Management. It seems like just the other day when we were all talking about our senior’s farewell as they move on. I remember thinking that it would be hard to say goodbye †¦ and I was right – it is hard. Yet I consider myself fortunate to have met such a special person †¦ a person that we care so much about †¦ that it makes saying goodbye to them hard! As we say goodbye, we remind ourselves that farewells are not forever, nor are they the end. They are simply words to say that we will miss you dearly and that we will remember you fondly. I still remember the day when I first met my seniors and to tell the truth I was really terrified by those sweet funny things which they made me and my class fellows do. But later we all realized that it was just to increase our confidence level and to decrease the communication gap among us. And I hope that this is quite an example to demonstrate their well wishes for us. Although we may be separated by time and distance in the interim, nothing will diminish the important role that you have and always will play in our lives. We wish you happy adventures, fantastic new friendships, amazing experiences and the journey of a lifetime. Most of our life is a series of images. They pass us by like towns on the highway. But sometimes, a moment stuns us as it happens. And we know that this instant is more than a fleeting image. We know that this moment†¦ every part of it†¦ we will live on forever. In the end I would like to say that where ever you go you will remain closer to our hearts. And May you conquer new fronts in life. May God bless you with a happy successful life and I..

MR250 Unit 7 Reading Essay MR250 Unit 7 Reading Essay MR250 Unit 7 Reading-Chapter 8 Cardiology and Hematology The cardiovascular or circulatory system consists of the heart and the blood vessels (arteries, capillaries, veins) (see Figures 8-1 and 8-2). The purpose of the system is to provide rapid delivery to the tissues of oxygen from the lungs; nutrients, minerals, vitamins, and water from the digestive system; hormones from glands; and white blood cells from bone marrow and lymphoid tissue, while removing waste products and delivering them to the lungs (carbon dioxide), liver (broken-down red blood cells), and kidney (surplus water, nitrogenous wastes) for excretion. Anatomy in Brief The heart is a pump- actually two synchronized pumps, each handling a different segment of the circulating blood at any given moment. The right atrium(antechamber) and the right ventricle receive venous blood from the systemic circulation and pump it into the lungs for gas exchange. The left atrium andleft ventricle receive freshly oxygenated blood from the lungs and pump it through the arteries into the systemic circulation. The contraction of a heart chamber is called systole; relaxation and refilling is called diastole. Valves in the heart (one for each of the four chambers) prevent back-flow of blood from a chamber during systole. The heart is encased in a protective sac called the pericardium. The names of the coronary arteries and branches are frequently mentioned in angiographic and surgical reports. The major vessels are the left main coronary artery, the left anterior descending (LAD) coronary artery, the right coronary artery (RCA), and the circumflex coronary artery. Names of branches of these take on additional terms, such as the left anterior descending diagonal (LADD). Other vessels to remember are the circumflex marginal, distal branches, and the posterior descendings. The major conduits are the aorta and pulmonary artery. The valves are aortic, mitral, pulmonary, and tricuspid. Terminology Review anemia Deficiency of red blood cells. arrhythmia Irregular rhythm of the heartbeat, with or without an abnormally slow or fast rate. ascites Swelling of the abdomen due to effusion of fluid into the peritoneal cavity. auscultation of the heart The physician notes the quality and loudness of heart sounds heard through a stethoscope at the four valve areas. bradyarrhythmia A pulse that is both irregular and abnormally slow. bradycardia Abnormal slowness of the heartbeat (pulse less than 60/min). bruit A rough vascular sound, synchronous with the heartbeat, heard on auscultation over a narrowing in an artery. cardiomegaly Enlargement of the heart. clubbing Club-shaped deformity of fingertips, seen in chronic pulmonary disease. cor pulmonale Dilatation, hypertrophy, or failure of the right ventricle due to acute or chronic pulmonary disease. crepitant rale A fine crackling rale. dependent edema Edema of the lower extremities, aggravated by the dependent (downward hangi ng) position. diaphoresis Sweating. dyspnea Shortness of breath. edema Swelling due to the presence of fluid in tissue spaces. effusion An abnormal accumulation of fluid in a body cavity, such as the pericardium. ejection fraction (EF) The percentage of the blood contained in a ventricle at the end of diastole that is ejected from the heart during the succeeding systole, normally 65% or higher. embolism Obstruction of a blood vessel by a detached blood clot, air, fat, or injected material. exudate A material deposited in or on tissues as a result of inflammation or degeneration and consisting of protein-rich fluid, inflammatory cells, and tissue debris. fibrillation Rapid, random, ineffectual twitching of cardiac muscle, instead of normal regular systolic contractions, due usually to metabolic or coronary vascular disease. Whereas atrial fibrillation can continue for years without serious impairment of health, ventricular fibrillation is rapidly fatal. gallop rhythm A cardiac rhythm that simulates the sound of a galloping

Rhetorical Criticism of Two Famous Speeches essays

Rhetorical Criticism of Two Famous Speeches essays History is made up of significant events which shape our future, and outstanding leaders who influence our destiny. Martin Luther King Jr. and John F. Kennedy contributed to our history and ultimately, our destiny, in many ways. The events which took place in and around Martin Luther Kings life were earth shattering, for they represented an America which was hostile and quite different from America as we see it today. Black Americans needed a Martin Luther King, but above all, America needed him. On August 28, 1963, on the steps of the Lincoln Memorial, in front of over 250,000 people, Martin Luther King gave an inspirational speech regarding freedom and liberty. His charismatic leadership inspired men and women, young and old, black and white, all over the world to rethink their views of segregation and discrimination. In his speech he says Now is the time to open the doors of opportunity to all Gods children. He states that we as Americans must ...not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred. I think this can not only be compared to the previous segregation of the 1960s, but also now, as not only African Americans, but people of the Muslim religion and others are still being discriminated against. John F. Kennedy also spoke of freedom in his Inaugural Address on January 20, 1961 in Washington D.C. He explains, We observe not a victory of a party, but a celebration of freedom. Kennedy addressed many different topics, but always came back to the idea of liberty. In his address, President Kennedy declared that "a new generation of Americans" had taken over leadership of the country. He said Americans would "... pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty." He told Americans: "Ask not what your country can do for you-ask what...

How to Encourage Your Child on Test Days

How to Encourage Your Child on Test Days As the About.com test prep expert, I often get emails from parents asking for help with things like studying with their children, test prep techniques, easing test anxiety and more. Recently, I received an email from a mom who wanted nothing more than to encourage her daughter on test days. She could perceive - although nothing was said - that something wasnt quite right with her child on days when she had a presentation or test to take. She wanted to support her daughter in the kindest way possible.   Read the email she sent to me and the response I offered her to help her child feel the best she possibly could on test days.   Hi Kelly, How can I be more encouraging to my daughter on test days? She hasnt said that shes worried or anything, but I can just tell that something is up with her when she has a quiz or exam. Is there an activity we could do in the morning on the way to school? Kind regards, ~~~~~~~ Dear ~~~~~~~, If your daughter needs encouragement on test days, perhaps shes experiencing some test-taking anxiety, which can stem from different emotional places. To find out whats bothering her, start a conversation on the way to school since you drive her there every morning. Its a great time to have a conversation since the pressure is low - you have to watch the road and she can look out the window if she doesnt want to make eye contact.    Use a statement like, I can tell youre feeling discouraged about something. Is it the test? Would you like to tell me your feelings about it? This kind of conversation starter gives her some wiggle room if shes not up to chatting, but more than likely, shell open up about her worries if theyre test-related because you may have a solution for her. So probe a bit. Does she have a fear of failure? Is she worried about disappointing you or her teacher? Does she feel like shes not prepared? Once you know the root of the discouragement, you can encourage her by sharing your own experiences and boosting her self-esteem. Start by discussing moments in your life when youve been similarly discouraged. (Fear of failure during a new job? That time you felt unprepared for your finals in grad school?) Talk about the ways you overcame it to go on to complete the task you needed to do. Or, tell her about your failure. Its good for a kid to see that her parent is always perfect. Tell her what you learned from failing.   Then, boost her confidence with heartfelt praise. Describe one of her strengths; maybe shes a great shot in basketball or a creative writer. Show her how she can use those skills on test day. Scoring two points in hoops requires concentration, and since shes already good at that, she can use her powerful focusing skills to zoom in on the right answers. Being a creative writer means she can think outside the box. Confidence in one area can cross into others, especially if you help build the bridge. Most importantly, let her know that her score will never impact your love for her. Youll love her just as much whether she bombs the test or aces it. Even if she knows it already, hearing you say that she has your devotion regardless of her actions may help calm her anxiety if shes been telling herself something different. All my best to you, Kelly

Economics of war Research Paper Example | Topics and Well Written Essays - 2000 words

Economics of war - Research Paper Example The causes of war have been different over the years and so have been their consequences. While come believe that wars are wrong no matter why they are caused and what is gained out of them; others believe that all’s well that ends well. But wars have never ended in good only. When it has resulted in a power fight and one nation seems to have won it, it has also lost the blood of many of its dedicated soldiers and other innocent nationals of its area. These days, almost every nation is equipped with nuclear weaponry making wars more deadly than ever. The first nuclear attack in the world was on Nagasaki and Hiroshima at the time of the end of World War 1. It marked the end of these cities and the civilizations that nurtured there. With the years going by, nuclear weaponry has only improved, thereby, indicating that now if one nation decided to blow up another using its nuclear power, it most likely to destruct a large part of the globe (Poast, 115). Indeed, the loss will be mu ch greater in emotional, financial and earthy sense than anyone can imagine. This is why it is very important for nations to carefully understand the economics of war before indulging themselves in such an activity. We are here not only to conquer places and make money but also to learn to live in harmony with each other. Every nation, color, creed and civilization is different from the other but this is no excuse for a war, we need to understand and accept these differences and in fact cherish them (Walzer, 200). Economics of war The most fundamental concept of Economics is of opportunity cost. Opportunity cost is the cost of what we forgo for what we gain or hope to gain from anything that we consume or purchase or decide about. For example, if a nation wishes to indulge in a war with another nation, it needs to first evaluate what it may gain. It may achieve success, money, land, power, slaves etc. it also needs to evaluate what it may lose in the process. And it may lose all tha t it may gain in addition to the lives of many innocent people. Also, it would waste its time and resources which may have been put to better use otherwise(Arnson, 45). Thus this evaluation of economics of war is essential for all the nations today. Any nation that decides to posing a war without thinking of its consequences will be doing more harm to itself and the world than it can imagine. Wastage of scarce resources The world is full of scarce resources. We need to use them very carefully or we will deprive ourselves and our coming generations of blessings like electricity, locomotives and other machines that make our lives much easier. Wars on the other hand require a lot of resources, a lot more than we can otherwise imagine consuming in the same time frame. Thus, when indulging in warfare, a country needs to be sure what it is at the risk of losing. Weaponry is expensive so is fuel that is used to drive large tanks and nuclear weapons and missiles are very expensive and destr uctive. A country may very well use the economic resources that it plans on warfare to improving its own nation’s industries, roads, parks and other national amenities thereby improving the living standard of its nationals (Egnal, 314). The world is a global village. We all live in a very interrelated surrounding. The ecosystem is balanced because one thing supports the other. It is all like a large heap of books, one on the other. The war may be a blow

Additionally, the water needs to be of lower temperatures, which are some of the ideal conditions for surfing. The 9.0 Japan earthquake of March 11, 2011 was indeed a surprise to many. Scientists, despite having predicted the earthquakes occurrence, never expected its large size. Additionally, the earthquake resulted in the death of approximately 18,000 people, even though warnings were issued especially in people’s cell phones. The earthquake also shifted the earth from its normal axis of rotation through the redistribution of mass. Question 2: Looking at the Ring of Fire, name 8 other countries, besides Japan, that are familiar with frequent earthquakes. Tell me about 1 of them that made headlines in the news within the past year. In the ring of fire, other countries familiar with frequent earthquakes besides Japan include Canada, United States, Costa Rica, Mexico, Bolivia, Chile, Guatemala, and Russia. One of the nations that has made headlines in the past year is Costa Rica, in which a powerful earthquake of a magnitude of up to7.6 shook the nation and a wide swath of Central America early in the morning in mid-2013, making substantive news headlines. Pacific Ring of Fire refers to an area with frequent occurrences of earthquakes and volcanic eruptions, contributed to by tectonic shifts in the earth’s plates. Because of such factors, the pacific ring of fire experiences an increased number of tsunamis considering the frequent movement of the earth’s plates. There exist three major types of tides, semidiurnal tides, mixed tides, and diurnal tides. Semidiurnal tides involve the existence of two high tides of equal heights and two low tides of equal heights. Mixed tides on the other side have two periods of high water and two periods of low water each day; however, the tidal heights are not equal.

Microfinance Essay Example | Topics and Well Written Essays - 250 words - 2

Microfinance - Essay Example The government gains significantly as its efforts to improve the living standards of its citizens are boosted through the efforts of microfinance. Lastly, for microfinance that goes public, stockholders are another major stakeholder and their concern is gaining dividends from their shares. There is no one stakeholder that may be considered more important than the others. Microfinance charges very high-interest rates but paid over a very short period of time. The rates are multiple times higher than even those charged by contemporary commercial banks. Further, the rate of repayment is extremely high despite not being secured tangible. This ensures that through the issuance of loans, microfinance is able to make huge profits which sustain them. To deal with life cycle issues, microfinance offer loans with different interest rates. For those who are extremely poor and unable to pay interests, they are given loans with no interest charged. This helps them to build business stamina, especially during hard economic times. One governance mechanism that microfinance use is social security in loans issuance. Since members are poor and do not have property to offer as security against loans to be acquired, collateral for borrowed money is assured intangible communally. As such loans are acquired only through groups. Each member of a group is liable for a loan borrowed and this alone provides an impetus for a member to persuade each other to pay their share of the loan without defaulting.

Assessment techniques Essay Example | Topics and Well Written Essays - 2000 words

Assessment techniques - Essay Example Critical thinking plays a big role in the whole concept of the consideration of new ideas, the subsequent choosing of the best options and the decision whether or not to modify them further. The Use of Critical Thinking Skills in Teaching Critical thinking skills are a challenge in both face-to-face teaching settings as well as in the provision of online courses because there is a need for students to be completely present in the moment during the lesson. It is much easier for students to merely cram information into their memories without necessarily understanding it and then restate it when they are required to during examinations or tests (Dobrovolny, 2006). Cramming information into memory is the easier way of retaining information without being fully involved in the learning process. It is something that is done in many educational institutions today. However, it is harmful to students in the final analysis because they are left in a situation where they have no skills in fully assessing different subjects or forming their own opinions about them. Reiterating information only calls for a student to sit in the lecture and pretend to understand what is being taught even though his or her mind may be thinking about something else. As long as the student has memorized various meanings, he is content because he can repeat this material to himself later until it is ingrained in his memory. It will then be easy to restate it just as he remembers it in any examinations where it may be required. The use of critical thinking skills, on the other hand, calls for the student to be fully engaged in associative or active learning. Critical thinking entails the use of various skills in the consideration of a given subject. These skills include interpretation, observation, inference, analysis, explanation, and evaluation. The student engaged in critical thinking also takes into account the context in which the material is presented, theoretical constructs for comprehendin g the subject matter, and the techniques used to come to a decision about the final answer. The use of critical thinking skills does not just entail the use of logic, but also the consideration of credibility, relevance, accuracy, significance, and precision. When a teacher wishes to engage her students towards thinking critically about a subject, she encourages them to use their reason to determine the next steps in finding the real answer; even if this might result in disparities in the findings. She will also encourage inquisitiveness among the students, and direct them towards using a systematic approach to finding solutions for different problems. Naturally, it is easier for teachers to encourage students in bricks-and-mortar institutions to adopt these methods of problem solving than it is for them to encourage students in their online classrooms or hybrid environments. Hybrid settings describe a situation where the teacher uses a combination of traditional classroom as well a s online instruction to disseminate lessons to students. In traditional classrooms, teachers are able to monitor students on a personal basis and some can even determine which students are ‘present’ and which are not. This means that they will be able to call the attention of

Cooking Is My Hobby Essay Example for Free

Cooking Is My Hobby Essay I enjoy cooking because it keeps me happy in my life. Whenever I feel sad or upset, cooking ease that for me in a big way. I started cooking when I was 6, but it was as simple as putting ham and cheese between 2 slices of bread and used my favorite condiment of maynaise and let it heat up for about 30 seconds. When I grew older, my knowledge of food grew to new depths when I learned how to cook American food on the grill when I was 13 and my dad was the sole reason why I got better since he explained to me how to use temperature control. The 1st dish I made on my own without any kind of assistance was Alaskan Cod with Lemon Pepper which I enjoyed very much when it was baked in an oven. Now, in my college years, I evolved into making cursine in many cultures such as tacos from Mexico, crepes from France, peking duck from China, and pizza from Italy using my ingredients I purchased from HEB, Fiesta, or Chinatown in my hometown. Cooking is the only thing in which I know how to do best and I usually cook for my family, relatives, friends, or people whom I do not know. Sometimes, I cook multiple of one thing for homeless people and disturbute them across the city. My least favorite thing to cook is vegetables since I do not like them, but if someone requests them on their plate, I will not be unwilling to cook them. Instead, I would embrace their desires and make it for them. I have invested hours of my time per day to be more knowlegable about different cooking methods from various chefs instead of just one in order to be prepared for different styles of cooking and perferences from guests. My signature dish is pork and leek dumplings with either soy sauce or vinegar or my orange chicken with basil and coconut broth so if you are ever in my area, I will be willing to cook for you.

Extreme Weather Events In The Uk Environmental Sciences Essay

Extreme Weather Events In The Uk Environmental Sciences Essay Intro: Global Warming is an undisputable cause of climate change in which the major cause of climate change is mostly induced by humans (anthropogenic), and not simply by the natural course of nature. The severity of its effects to weather conditions is always increasing day by day. Extreme weather conditions may range from floodings, heatwaves, droughts and other severe weather conditions. We are now experiencing each year drier plus burning summer seasons due to the increase in heat waves and global warming, whilst we have warmer plus rainier winters as a result of increased rain, snow and hail precipitation. Even stormy weather is on the increase. [1- 4] Who does it affect?: This issue of random extreme weather conditions affects everyone in every national and local communities across the world (even in the UK), particularly the most vulnerable people.. Disruption to the normal farming conditions due to random climate change will cause an imbalance to the soil quality which will mean that crops will not be able to grow[5], and fewer animals will be fit for consumption due to the increase of food poisoning and water borne diseases, therefore farmers will lose out on potential job earnings. This will make farmers less likely to keep up with their bills and live less comfortably due to the reduced income. At the same time, it will affect us as there will a shortage of good, nutritional food. They may resort to increasing food prices. Since farmers supply food for many different food companies, it could indirectly pose problems to companies regarding the supply of food and marketing of their food products. Drought which is the result of increasing global temperatures can severely affect water supply companies. Water supply companies may increase their water usage prices by at least 5 percent each year[6] due to the drought and the ever increasing demand of water. Climate change and extreme weather can affect our health and make us more susceptible to much more illnesses than now and even cause death. Examples of illness conditions are hay fever, cataracts and skin cancer. It could even cause occurrences of Dengue fever and West Nile virus which are tropical diseases not normally found in the UK.[7] Temperature rises and heatwaves are becoming more frequent than usual. The Met Office conducted an interesting research which showed Englands highest temperature recorded in a day. One of the figures was particularly striking which was found in Kent from the southern part of England. It revealed that Kent had the highest temperature recorded in January 2003 which was 17.6 degrees, and 38.6 degrees in August 2003 showing a shocking 21 degrees increase in just above 6 months.[7] Such extreme temperatures can present health problems to these vulnerable people. When exposed to heat long enough, Heat exhaustion may result to these people and possibly may lead to dehydration and even heatstroke which is a life threatening medical condition. Also, it will increase the amount of harmful UV radiation contacting our skins so increasing our skin cancer risk. Since Britain may experience further increase in temperatures in the near future, this problem needs much attention. Moreover, the heatwaves may induce power cuts and increase water demand which will affect everyone including business people. Technology and water are in ever increasing demand therefore disabling the available technology around us due to power cuts, more droughts and increasing water bills may cause severe problems in our ability to cope without them at work and leisure. Also if business buildings are severely damaged, they may build a new building at another site which may cost more money than minor repair. Not only does it affect us humans, it affects plant and animal life too. More heatwaves and other severe weather conditions will increase the incidence of forest wildfires, contamination of river water and damage to habitats. This will harm the plant and animal wildlife and they may struggle to survive. It will ultimately lead to affecting our lifestyles in the long term.[8] Examples of damaging cases: In the UK (England and Wales), floods that occurred at Autumn in the year 2000 between October to November have resulted in massive damages which have costed at least  £1.3 billion.[1] That autumn was the wettest autumn season ever recorded since 1766, demonstrating more than 500mm of rainfall between September to November, and insurance claims up to  £3.5 billion were called for as a result of at least 10,000 flooded homes.[1, 3] . Another case in the UK that is increasing even today is in the farming industry. Due to climate change, there is now a rapid growth of certain parasitic worms particularly the Helminth family that are affecting cattle and sheep livestock (affects both young and adult livestock). The most common Helminths are the roundworms (gastrointestinal nematodes) and the flatworms (flukes). The roundworms are thought to drastically reproduce far more quickly in higher temperatures and adapt very well to its surroundings due to its biotic potential and genetic diversity.[9-10] This means that they can potentially thrive in all four seasons. Global Warming may increase mean daily temperatures and therefore cause a upsurge in the reproducing rate of roundworms.[9] A specific roundworm species called Teladorsagia grows really fast in the Spring and have been causing heavy damage to young lambs and even death in South East Scotland.[10] There had been an outbreak in 2004 of another specific roundworm called Nematodirus battus, which have adapted to the Scottish weather so that they grow not only in Summer but also Autumn and Winter. They have been seen in young and old lambs.[10] Furthermore, the European heatwave that the UK experienced in August 2003 was the hottest heatwave ever recorded. Altogether in Europe, 20,000 people died because of the heatwave. Out of this, a minimum of 2,000 people from the UK died as a result of excessive heat. One third of the 2,000 deaths in the UK were associated with air pollution. It even affected roads, train services, water and energy suppliers plus farmers. [11] Not only that, home building foundations (subsidence) were being damaged due to the drying of water from the soil and building foundations causing cracks to form and non-level home foundations. The subsidence insurance claims soared up to  £400 million. [12] Vulnerability of certain people types: In the UK, the magnitude of Heatwaves and rising sea levels (which may lead to larger wave heights, more floods and faster coastal erosion) are rising. Heatwave effects may be particularly significant in the South and East parts of the UK. These extreme weather conditions pose certain vulnerable individuals who:[2, 4] have low income support They cannot afford to buy accessories and other essential items that may help against short term and long term extreme weather problems. live in low quality constructed houses (particularly more found in coastal regions)- buildings will trap the heat, making their homes hotter and more susceptible to weaker house foundations. are elderly or quite young -more susceptibility to disease due to weaker immune systems. have poor health due to illness may increase their chances of catching other major or minor diseases, especially in cities. are isolated from social links finding environmental, social and emergency help may be harder live near the coastal regions -particularly in the East part of England as these coast have low lying, soft sediment coasts that erode much more quicker. Who live in cities referred as urban heat islands, which means that urban areas produce more heat than countryside towns. Makes them more susceptible to illnesses and possibly cause city infrastructure problems.[13] Cause of severe climate change and science: Many scientists agree that the major cause of the drastic climate change, global warming and extreme weather conditions are due to pollution mainly by certain human activities (anthropogenic) that emit greenhouse gases (nitrous oxide, water vapour, methane and carbon dioxide (CO2)). Of course there are natural equilibriums such as the carbon cycle, nitrogen cycle and the water cycle that tries to balance the levels of these gases. Also, the ozone layer (O3) helps protect us from the harmful UV radiation from the sun. But these natural equilibriums have been disturbed by human activities. So now temperatures and sea levels are rising (glaciers in the Antarctica are melting as proof). [14-20] A few examples of the human activity that has damaged the natural cycles are:[14-20] the cutting of trees (deforestation) increases the levels of carbon dioxide in the atmosphere due to burning of trees. Trees are important in the absorption of carbon dioxide and water from the environment using the process called photosynthesis to release oxygen (O2) to the environment. driving cars, buses and other transport (especially airplanes) build-up of carbon dioxide and other gases in the atmosphere. Accounts for 21% of the emission of greenhouse gases in the UK. industrial cooling towers- increases the amount of heated water into the atmosphere. use of fertilisers and pesticides for farming the ones that contain nitrogen increase the levels of nitrogen in the biosphere via contamination of water due to heavy rainfall. Therefore it affects humans, fish and animals. Accounts for 8% of the emission of greenhouse gases in the UK. Burning of fossil fuels done to produce energy. The biggest contributor in the UK of releasing greenhouse gases to the atmosphere (65%). aerosols that contain CFCs (chlorofluorocarbons) the CFCs are sent to the atmosphere in which the UV radiation frees the chlorine from the CFC. This chlorine damages the ozone (O3) layer in the atmosphere. Some may argue that natural causes are significant to the climate change effects. It is known that eruption of volcanoes, the output energy of the sun, ocean currents and Earths orbit changes do contribute to this but only play a minor role.[17,20] Who can influence change?: The UK Government can help with the mitigation and adaptation strategies for sustainability development which includes social, environmental and economic improvements. Mitigation is trying to reduce the levels of greenhouse gases in order to reduce the temperature rises. Adaptation involves doing things differently in our lives to reduce the level of greenhouse gases. They must consult with other business leaders and organisations to ensure mitigation and adaptation strategies are implemented for sustainability. It could help the UK unemployment issue whilst helping biodiversity. However, greener solutions may require lots of financial and political help to implement them, which is the challenge. They need to use short and long term strategies for success. What currently is happening and what extras can be done? A study found that London was producing 44.71 million tonnes of carbon dioxide in 2008 from which major culprit the business workplaces contributed by a shocking 19.2 million tonnes of carbon dioxide(43% of total). Also, homes and transport were emitting large amounts of carbon dioxide. The Mayor of Londons mitigation strategy to climate change is to lower London CO2 levels by 60% for 2025. It is currently under public consultation but sounds promising. The mitigation programmes include RE:FIT, RE:CONNECT, RE:NEW, the Green500, Electric Vehicle Rollout and Operation Decentralised Energy. It will involve installing new energy saving technology at businesses and homes, encouraging community to reduce CO2 levels, recycling waste into energy and get 1,000 electric vehicles and more. [21] Advantages are that it explores different ways that can bring a change in CO2 levels so results can be seen relatively quick, it may provide many jobs in a variety of sectors for the unemployed as it is a concerning issue in the UK, the scheme is easy to follow, helps people save more money in the long term. It may have problems with the project being expensive and refuelling electric or hydrogen fuelled vehicles as it may take longer. Overcoming resistance needs more public awareness about the benefits, business and public role models to show public being greener is possible, and easy. The Queen made a speech recently in which she said that policies and legislations of the energy security and green economy Bill are to be introduced and implemented by the Government into homes and business across the UK. This will enable more use of energy efficient technology whilst ensuring management of energy supply to keep up with energy demand, reduce greenhouse gases especially carbon dioxide, encourage people to coincide with the demands set by the Government, and fund more projects that help the economy whilst reducing greenhouse gases via the Green Investment Bank.[22] This sounds like a good idea for mitigation and adaptation towards climate change. In the UK, Business and Government Leaders like David Cameron need to encourage greener jobs for benefit of the environment, economy and society. Unemployment still is a big issue across the world. Many people including graduates are claiming unemployment benefits and are unable to find work due to the credit crunch. Women are especially finding it difficult. In March 2011, the number of men on the benefits are 988,200 whilst number of women are 462,300.[23] Recently, The Green Economy Council have fetched big business leaders (eg. Joe Greenwell, chairman of Ford UK) in its council to provide professional advice to the Government on policies that affect green business infrastructure, investment and regulation. They are setting up policies like Green Deal which may open a thousand new jobs. But policies need to be clearer on low carbon economy. [24-26] They have not considered solar energy which has the potential to thrive. Mazhar Bari of SolarPrint said in 10 years, it could create 10,000 jobs, à ¢Ã¢â‚¬Å¡Ã‚ ¬1 billion of exports and à ¢Ã¢â‚¬Å¡Ã‚ ¬140 million of annual tax revenue.[27] Public Biodiversity awareness needs to be more focused in the UK particularly to the medium/low class people due to low income. Certain celebrities can probably help with this. Solutions need to be easy, practical, involve little effort and cheap. Health adaptation policies look good like the Heatwave Plan, Climate Change Act 2008 and the Annual Public Health Report of the Director of Public Health 2010 have been introduced to help healthcare professionals and public adapt to climate change and help health sector Government bodies and media to raise awareness of solutions. Also, diet and health advice to public is given by healthcare professionals. [28,29] As far as farming is concerned in the UK, the Common Agricultural Policy needs to be reviewed again by DEFRA to convince the Government the benefits of the scheme.[30] Funding cuts to UK flood defence may have serious consequences as those seen in November 2010 at Cornwall where 5 million poor people were at risk from flood damage. I think some property insurance cover and belongings can help in advance of flooding event so that less money is spent in aid. [31] Conclusion: Much effort still needs to be done by everyone, although the Government and others have actively tried to reach sustainable development through mitigation and adaptive approaches. They seem to be in the correct frame of mind but farming and flood aid strategies still needs to be tackled.

Environmental Ethics Essay -- Environment Global Warming Climate Chang

Ethics is the study of what is right and wrong in human conduct. Environmental ethics studies the effects of human’s moral relationships on the environment and everything within it (Stanford Encyclopedia of Philosophy, 2008). The ethical principles that govern those relations determine human duties, obligations, and responsibilities with regard to the Earth’s natural environment and all of the animals and plants that inhabit it (Taylor, 1989). The purpose of this paper is to reveal environmental issues that are threatening the existence of life on Earth, and discus our social obligations to refrain from further damaging our environment, health and life for future generations. I will discus the need for appropriate actions and the ethical application in the decision making process on solving environmental concerns. Environmental Concerns The environment has been under attack since the dawn of man. Without the environment, man could not exist. Herein lies the dilemma, man takes from the earth what he needs to survive, food, water, shelter, and the very air he breathes. However, the ever-rising population of man demands more of these essentials at a rapid rate, therefore, more is being taken than the earth can replenish. The human populous and concentrations of pesticides in food crops, started to be seen as an environmental crisis in the 1960’s, which acted as the stepping-stone for environmental awareness. In 1967, historian Lynn White published an essay on the historical roots of the environmental crisis. Whites essay created many academic debates over the Judeo-Christian mode of thinking, which encouraged the exploitation of nature for human consumption. The ethical dilemma arises from the concern of whether or not it was mor... ...man sources of greenhouse gas emissions are expected to rise due to the growing populous, this growth may be reduced by Bush’s plans to increase efforts to use newer, cleaner technologies and measures. These plans will only be effective if everyone, not just in the United States, but the entire world, participates and becomes aware of the ethical dilemmas challenging our very existence. The environment is a part of us and we of it. We cannot survive without each other. Since the dawn of time, it has nurtured and provided for us. Now it is our turn to nurture and preserve the environment. The future in uncertain, but if the entire human species can adapt a more reasonable lifestyle, there is hope for the environment and every living thing in it. Time is of the essence, therefore, immediate actions and ethical decisions are necessary for survival of the planet.

Police work with juveniles Essay

Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This term paper tackles the issue of police work with juveniles.   For purposes of this paper therefore, juvenile delinquency should be understood to refer to any antisocial or criminal behaviour by children or adolescents (Quint, Andrew Reisig & Mueller, 1996)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   On Friday June 1996, a 9 year old and 11 year old boy were charged with the rape of an 8 year old pregnant. In addition, a pregnant girl was shot by another student in St. Louis Miami almost during that time (emergency net news, 1996).   These are just but cases of Juvenile offences that the police have to deal with.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Juvenile policing has its roots in 1899 in cook county Illinois, where the first court was created as a result of ideological changes in the cultural conception and strategies of social control during the 19the century; an event that culminated into a century long process of differentiating youths from adults offenders( Quint et al. 1996)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   What then is the police role in juvenile policing?   Just like the adult system of criminal justice, the juvenile justice system also has three basic components, the police, courts and corrections (Larry & Welsh, 2004) More often than not, whether or not a juvenile is processed into this system is dependent upon the outcome of an encounter with the police.   It is therefore true to say that, the police serve the role of the gatekeepers to the juvenile justice system.   They thus begin the criminal justice system. Also, upon the arrest of a juvenile offender, the law provides for the police to release the juvenile to his or her parents or take the offender to a court (Quint et al. 1996) A new view has however emerged within the police themselves. Rather than seeing themselves as crime fighters who track down serious criminals or stop armed robberies in progress, many police departments have adopted the concept that their role be maintaining order and being a visible and accessible component of the society(Larry & Welsh, 2004)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Police research and other related studies indicate that these offender of violent juvenile crimes are likely to turn up to world be junior terrorists who can be of rivaled some of the worst terrorist organizations in the world.(Quint et al 1996)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The arrest procedures for juvenile offender differ from place to place but generally, arrest becomes the primary option of securing the juvenile’s attendance to court.   In addition, a written notice can be issued by police for the offender to appear in court (Larry & Welsh, 2004). This is however mostly given to minor offenders.   The investigating officer then notices the parent or guardian about the arrest of the time, date and place where the offender is to appear.   While doing this, the police are supposed to exercise discretion to enhance the child’s rights and divert the child away from the mainstream criminal justice system(Larry & Welsh, 2004)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Search and seizure is another method of police methods of investigation.   The law governing search and seizure is typically the same for both adults and juveniles (Larry & Welsh, 2004). This procedure involves among others photographing, fingerprinting, lineups and record keeping.   Children however, just like adults are also protected against unreasonable search and seizure under the fourth and fourteenth amendments of the constitution (Larry & Welsh, 2004)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There is also custodial interrogation which requires the offenders   to be questioned often within the presence of their parents or attorney.   This is because any incriminating statement arising from such custodial interrogation can be used at trial (Quint et al. 1996)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Because of the informality that has been built into the system in an attempt to individualize justice, much discretion needs to be exercised.   Daily procedures of juvenile personnel are rarely subject to judicial review except when they violate the youth’s constitutional rights (Larry & Welsh, 2004) and as a result, discretion sometimes deteriorates into discrimination and other abuses on the part of the police.    Too little discretion gives insufficient flexibility to treat juvenile offenders as individuals while too much leads to injustice (Larry & Welsh, 2004).   Police for instance are likely to act formally with African American suspects and use their discretion to benefit whites (Larry & Welsh, 2004). Other factors include environmental factors whereby the police have that in born mentality within them that certain places, or if a child comes form a particular place, then he/she is likely to be an offender.   This stereotypy thus falls under the environmental factors.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Police bias can also be as a result of the situation and conditions under which the child is arrested.   If the child brings complications such as putting up a resistance against the arrest and therefore fights the officer, or merely has a bad or negative attitude, then he is likely to be arrested in such a case discretionary justice is likely to take place (Larry & Welsh, 2004). It should be noted also that discretionary decisions are made without guidelines from the police administration. As noted earlier, there are many factors that influence the decisions made by the police about juvenile offenders. among the ones not mentioned include, the seriousness of the offense, the harm inflicted on the victim and the likelihood that the juvenile will break the law again (Larry & Welsh, 2004).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The police have however taken the lead in delinquency prevention by employing a number of strategic measures some of which rely on their different powers. Others have relied on schools, the community and other juvenile justice agencies (Quint et al, 1996).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   One of these strategies of contemporary prevention relies on aggressive patrolling at specific patterns of delinquency.   This is what we refer to as aggressive law enforcement.   The police here target gang areas and arrest members for any violations.   The tactic however has not proved to be effective since in most cases, the results tend to be unsatisfactory (Larry & Welsh, 2004).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In 1996 for example, the Dallas police initiated the strategy, which led to significant reduction in gang activity, targeting truancy and curfew laws but the saturation patrols proved ineffective (Larry & Welsh, 2004).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Police have also worked with schools to improve their safety and prevent delinquency in the community through organizations of various programs (Quint et al. 1996). The problem here however lies in the view that is held by some people over police in schools.   These people assert that this infringement on the personal freedoms of students (Larry & Welsh, 2004)   and that schools   should be left to run sovereignly.   There are also others who call for greater use of police in schools, especially those schools that have experienced violent incidents in the past by students against teachers (Larry & Welsh, 2004).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Community policing may also be employed here.   Community policing models are put in place aimed at improving relationships between the community and the police.   This will be important since many juveniles will then have a high regard for the police. Conclusion The ever-changing nature of juvenile delinquency thus calls for more experimentation and innovation in policing strategies inorder to prevent delinquency (Larry & Welsh, 2004). Among the first steps therefore should be tailoring policing activities to prevailing local conditions and providing for an enlargement in the community and other stakeholders      References Emergency Net News Service, 1996 http://www.emergency.com/juvycrim.htm Larry J.

Write the key features, listed below, into the correct life stage of development and most significantly affected age range. In your own words, provide an explanation of the term and how it affects the developmental stage. An example is provided for reference. For the purposes of this assignment, field marked N/A do not need to be completed. Teratogens Attachment ADHD Temperament Preoperational Thought PeriodIn-Vitro Fertilization ConservationSelf-Concept Refined motor skillsZygote Positive Reinforcement Sensorimotor Period Mobility Biological DevelopmentPsychological or Cognitive DevelopmentSocial DevelopmentConception and Pre-birthExample Teratogens are substances, including drugs, that cause malformations in the fetus (Zastrow Kirst-Ashman, 2010, p.54). For example, the text states that teratogens are Certain drugs affect biological development by causing malformations of body parts and organs. Newborn children of drug addicts, for example, experience a number of potential developm ental problems such as low birth weight, muscle tremors, and physical birth defects (Zastrow Kirst-Ashman, 2010, p.54). A zygote is a single cell formed by the combination of the genetic material in a womans egg and sperm. In-Vitro Fertilization is a process in which eggs are removed from a womans body, fertilized with sperm in a laboratory dish, and then implanted in the womans uterus (Zastrow Kirst-Ashman, 2010, p.90). N/A N/AInfancy The central theme of attachment theory is that primary caregivers who are available and responsive to an infants needs allow the child to develop a sense of security. Bowlby believed that the earliest bonds formed by children with their caregivers have a tremendous impact that continues throughout life. He suggested attachment also serves to keep the infant close to the mother, thus improving the childs chances of survival.Temperament is each individuals distinguishing mental and emotional nature that results in a characteristic pattern of responses to people and situations (Zastrow Kirst-Ashman, 2010, p.125). There are three broad categories of infant temperament that are often used as guidelines for determining normal infant behavior. The three categories of infant temperament are easy, slow-to-warm-up, and difficult. N/AChildhood ADHD, a psychiatric diagnosis, is a syndrome of learning and behavioral problems beginning in childhood (Zastrow Kirst-Ashman, 2010, p.146). Children often fail to give close attention to details and make  careless mistakes in their schoolwork or in other activities. Also, they have difficulties organizing their tasks and activities. They are easily distracted by extraneous stimuli and they tend to be forgetful in their daily activities Piagets second stage of cognitive development, the preoperational thought period, extends from approximately ages 2 to 7 (Zastrow Kirst-Ashman, 2010, p.116). Increased use of verbal representation but speech is egocentric. The beginnings of symbolic rather than simple motor play. Can think about something without the object be ing present by use of language. Conservation is the idea that a substance can be changed in one way while remaining the same in another (Zastrow Kirst-Ashman, 2010, p.115). This means that the child understands that although the appearance of something changes, the thing itself does not. Fine motor skills are necessary to engage in smaller, more precise movements, normally using the hands and fingers. Fine motor skills are different than gross motor skills, which require less precision to perform. The sensorimotor period identifies a child as they progress from simple thoughtless reflex reactions to a basic understanding of the environment (Zastrow Kirst-Ashman, 2010, p.116). Behaviors are limited to simple motor responses caused by sensory stimuli. Children utilize skills and abilities they were born with (such as looking, sucking, grasping, and listening) to learn more about the environment. Baumeister provides the following self-concept definition the individuals belief about himself or herself, including the persons attributes and who and what the self is (Baumeister, 1999). The self-concept is how we think about and evaluate ourselves. To be aware of oneself is to have a concept of oneself.Positive reinforcement refers to positive events or consequences that follow a behavior and strengthen it (Zastrow Kirst-Ashman, 2010, p.169). Successful positive reinforcement results in a behavior occurring more frequently in the future. It can make learning fun, increase participation and cooperation, and help children learn valuable skills. Because of their mobility, children need constant supervision. Their interest in exploration, falling down, and getting into dangerous situations are all constant possibilities (Zastrow Kirst-Ashman, 2010, p.67). Baumeister provides the following self-concept definition the individuals belief about himself or herself, including the persons attributes and who and what the self is (Baumeister, 1999). Its psychological development due  to self-evaluation, but its also social development due to the benchmark we judge others by. References Baumeister, R. F. (Ed.) (1999).
