Essential Anatomy And Physiology Physical Education Essay

Essential Anatomy And Physiology Physical Education Essay Homeostasis refers to the bodys ability to maintain relatively stable internal conditions even while continually subjected to external changes. Body temperature, blood volume and heart rate are just a few examples of the hundreds of conditions the body regulates to maintain homeostatic balance. This internal equilibrium is so important that virtually every disease or disorder in the body can be traced to a homeostatic imbalance. The maintenance of homeostasis includes: Control of the water balance of the blood Control of blood sugar level Control of body temperature Control of blood urea level Each of the internal factors are maintained by a separate mechanism that is specific for that factor. However, all the mechanisms for homeostasis share common features: A specific sensor is able to detect the value of the factor being monitored Any deviation from the desired value (norm)is corrected so that the norm is more or less maintained The corrective mechanism involves negative feedback. For the body cells to survive and function properly, the composition and temperature of the fluids around the cells (intestinal fluid) must remain much the same. Corrective mechanism Rise above norm Norm Norm Corrective mechanism Fall below norm Various organ systems of the body act to maintain homeostasis through a combination of hormonal and nervous mechanisms. In everyday life, the body must regulate respiratory gases, protect itself against agents of disease (pathogens), maintain fluid and salt balance regulate energy and nutrient supply, and maintain a constant body temperature. All these must be coordinated and appropriate responses made to incoming stimuli. In addition, the body must be able to repair itself when injured and be capable of reproducing (leaving offspring). The human body must maintain homeostasis in order to function properly and aid in growth and development, disruptions to homeostatic functions can have triggered effects on the growth and development. Normal blood temperatureRegulation of body temperature by Homeostasis: Cold receptors in skin Warm receptors in skin Decrease increase Hypothalamus Heat gain Heat loss Vasodilation of superficial arterioles onset of sweating hair lowered as hair erector muscles relax and decreased metabolic rate. Vasoconstriction of superficial arterioles onset of shivering hair raised by contraction of hair erector muscles and increased metabolic rate. Feedback Feedback Negative feedback in the control of body temperature: Skin vasodilation sweating lowering hairs Heat loss centre in the hypothalamus Thermoreceptors in the hypothalamus Rise in blood temp Nerve impulse Nerve Impulse normal blood temp Blood at original temperature turns off corrective mechanisms Positive feedback occurs when the feedback causes the corrective measures to remain turned on, this causes the system to deviate more from the norm. One example is of neurones when a stimulus causes a small influx of sodium ions. Positive feedback occurs when there is a breakdown of control systems. In Certain diseases like typhoid fever, breakdown of temperature regulation resulting in a rise in body temperature leading to hypothermia, and vice versa if the body gets too cold (hypothermia). The human body systems, all play a part in maintaining homeostasis; they all have their own specific roles and parts. The human body systems work together in order to function effectively, no system would be able to work effectively on its own. Organ system Homeostatic function Cardiovascular Transports oxygen, nutrients and hormones secreted by the endocrine glands to tissue cells and transports wastes away from cells; defends against disease; helps control temperature, fluid, and pH balance. digestive Absorbs soluble nutrients after ingesting food and digesting it, eliminates nondigestible remains.   Supplies blood with nutrients and water for tissue cells. respiratory Captures oxygen and exchanges gasses at lungs and tissues, maintains breathing, helps control pH balance.   Supplies blood with oxygen for tissue cells and rids blood of carbon dioxide.   Helps regulate the acid-base balance of the blood. Skeletal Protects the body and provides support for locomotion and movement, stores minerals, produces blood cells. endocrine Coordinates and integrates the activities of other systems by secreting hormones, responding to stress, regulating fluid, pH balance and metabolism.   Works more slowly, with longer-lasting effects than the nervous system. muscular Produces body and internal movement, maintains posture, and produces heat that maintains body temperature.   Protects and supports internal organs. urinary Removes nitrogenous and other metabolic wastes from the bloodstream by excretion, helps control fluid balance, as well as the water-salt, and acid-base balance of the blood. nervous Receives sensory input, integrates and stores input, directs the body, and helps coordinate the activities of all the other organ systems.   It responds quickly to internal and external stimuli. The circulatory system is built up the heart, blood and blood vessels, which services all the cells in the body. Wastes are taken away and exchanged with oxygen and food nutrients. All cells in the body require oxygen and nutrients and they need theyre wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell. Components of the cardiovascular system Heart Blood vessels Blood Heart is a muscular pumping organ located in the medial to the lungs. The top of the heart, known as the hearts base, connects to the great blood vessels of the body; the aorta, vena cava, pulmonary trunk, and pulmonary veins. Blood vessels are the highways that allow blood flow quickly and efficiently from the heart to regions of the body. Three types of blood vessels, arteries and arterioles, capillaries, and veins and venules. Blood as a connective tissue, transports many substances through the body and helps maintain homeostasis of nutrients, wastes, and gases. Blood is made up of red blood cells, white blood cells, platelets, and liquid plasma. All of the organ systems in the body contribute to homeostasis, but the cardiovascular system, the heart and blood vessels is especially important. Without the cardiovascular system none of the other systems can function. The muscular system requires large amounts of oxygen from the cardiovascular system. Muscles cramp and freeze up when they do not get adequate oxygen supply. If in the case the cardiovascular system cannot pump enough oxygen rich blood to the muscles the body is unable to move. The cardiovascular system also helps in maintaining blood volume; it works in conjunction with the kidneys to maintain blood volume and composition. The cardiovascular system provides the blood pressure that the kidneys use to filter waste out of the body. The cardiovascular system and the skin help maintain homeostasis by regulating body temperature. When the body over heats, the blood vessels that serve the skin dilate. The cardiovascular system rushes warm blood to the superficial capillar ies of the skin. Heat from the blood radiates off of the skins surface, cooling the body. When body temperature drops too low, skin capillaries constrict. This prevents warm blood from reaching the surface of the skin. The heart pumps extra blood to the deeper vital organs. Nasal passage Air entering from the nostrils is led to the nasal passages. The nasal cavity that is located behind the nose comprises the nasal passages that form an important part of the respiratory system in human beings. The nasal cavity is responsible for conditioning the air that is received by the nose. The process of conditioning involves warming or cooling the air received by the nose, removing dust particles from it and also moistening it, before it enters the pharynx Pharynx It is located behind the nasal cavity and above the larynx. It is also a part of the digestive system of the human body. Food as well as air passes through the pharynx Larynx Consists of two pairs of membranes. Air causes the vocal cords to vibrate, thus producing sound. The larynx is situated in the neck of mammals and plays a vital role in the protection of the trachea. Trachea Airway through which respiratory air travels bronchi The trachea divided into two main bronchi. The bronchi extend into the lungs spreading in a tree-like manner as bronchial tubes. The bronchial tubes subdivide and with each subdivision, their walls get thinner. This dividing of the bronchi into thin-walled tubes results in the formation of bronchioles. The bronchioles terminate in small air chambers, each of which contains cavities known as alveoli. Alveoli have thin walls, which form the respiratory surface. The exchange of gases between the blood and the air takes place through these walls. lungs Lungs form the most vital component of the human respiratory system. They are located on the two sides of the heart. They are responsible for transporting oxygen from the atmosphere into blood and releasing carbon dioxide from blood to the atmosphere. The respiratory system is made up of the nasal passage, the pharynx, larynx, the trachea, bronchi and lungs. It is responsible for the process of respiration that is vital to the survival of living beings. Respiration is the process of obtaining and using oxygen, while eliminating carbon dioxide. Breathing occurs when air passes into and out of the lungs; its an involuntary process but can be controlled consciously. Breathing involves the movement of air in and out of the lungs in generated by differences in pressure inside and outside the body. The most important muscle used in breathing is the diaphragm, a muscular sheet between the base and the abdominal cavity. The diaphragm is assisted by the internal and external intercostal (which lie between the ribs) and by the neck and abdominal muscles. A person normally breathes in and out about 500ml (1pt) of air 12-17 times a minute. Breathing involves inhalation followed by exhalation, during inhalation the diaphragm and external intercostal muscles contract to expand the chest cavity. During forceful inhalation the neck muscles also contract. However during exhalation the chest cavity decreases, and the diaphragm and external intercostal muscles relax. In order to function, the body cells need oxygen. The respiratory system, w hich consists of air passages, pulmonary vessels, and the lungs, as well as breathing muscles, supplies fresh oxygen to the blood for distribution to the rest of the body tissues. In addition, respiration removes carbon dioxide, a waste product of body processes. Alveoli which are tiny air sacs of the lungs, they are elastic, thin-walled structures that are supplied with air by respiratory bronchioles. Tiny blood capillaries surrounding the alveolar walls allow oxygen to be carried into the bloodstream. In exchange, carbon dioxide diffuses from blood into the alveoli, from where it is exhaled. Gas exchange takes place in the lungs, where carbon dioxide from the blood passes into the alveoli through the respiratory membrane, a thin barrier that has several layers. Oxygen crosses the membrane in the opposite direction, from the alveoli to the blood capillaries. Homeostasis is hence maintained by the respiratory system in two of the following ways: gas exchange and regulation of blood pH. Gas exchange is performed by the lungs by eliminating carbon dioxide, a waste product given off by cellular respiration. As carbon dioxide exits the body, oxygen needed for cellular respiration enters the body through the lungs. ATP, produced by cellular respiration, provides the energy for the body to perform many functions, including nerve conduction and muscle contraction. Lack of oxygen affects brain function, sense of judgment, and a host of other problems. The bodys complex anatomical systems work closely together to support movement, blood circulation, digestion and other basic requirements of life. The muscular system consists of three types of muscle, each with a separate function. The functions of the muscular and skeletal systems are so intricately interconnected that they are often referred to by the single term, the musculoskeletal system. This system consists of bones, joints, tendons, ligaments, skeletal muscles, nerves, cartilage and the voluntary or striated muscles. They work together to protect the brain and internal organs, posture, blood cell formation, and fat storage. Smooth muscles make up important internal organs, like the bladder, arteries and veins. They interact with the digestive system, reproductive system and circulatory system. Smooth muscles control and regulate blood pressure and blood flow. The cardiac muscle is the heart itself, an involuntary muscle that interacts with the circulatory system to supply ox ygen to all the tissues of the body. Skeletal muscles are under voluntary control, meaning we can choose to move them. Movement of smooth muscles and the cardiac muscle is involuntary, under control of the autonomic nervous system. The muscular system also plays an essential role in homeostasis, which is the regulation of internal body temperature. Homeostasis is maintained by the hormones that increase osteoblast activity to build bone, called calcitonin which is released by the thyroid gland, and the release of parathyroid hormone which increases osteoclast activity and is released by the parathyroid glands. As long as both of these function normally, the bone mass stays the same, this is a homeostatic state of bone. If it goes out of balance you will either build too much bone or loose bone mass and develop osteoporosis. The nervous system is the bodys decision and communication centre.  The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of a persons daily life, from breathing and blinking to helping people to memorize facts for a test. Nerves reach from the brain to the face, ears, eyes, nose, and spinal cord, and from the spinal cord to the rest of your body. Sensory nerves gather information from the environment; send that info to the spinal cord, which then speed the message to the brain. The brain then makes sense of that message and fires off a response. Motor neurons deliver the instructions from the brain to the rest of your body. The spinal cord, made of a bundle of nerves running up and down the spine, is similar to a superhighway, speeding messages to and from the brain at every second. The CNS controls homeostasis as well as depends on it. The CNS controls homeostasis by us ing its receptors to sense changes in the bodys internal environment. E.g., certain receptors in the aorta monitor carbon dioxide and  oxygen  concentration in the blood. This information is relayed to the brain (most functions are controlled by the hypothalamus), and again through the CNS, the effector organs are signalled. Eg To increase or decrease the rate of breathing in response to carbon dioxide/oxygen concentration. The CNS comprises of nerve cells that depend on a very stable internal environment, especially in terms of sodium and potassium concentrations, without which it cannot function properly.

Attribution Theory

Discuss the types of attribution someone makes when they appraise a person’s behaviour. How may bias occur in their reasoning particularly if they have a very different background to the person they observe? Attribution theory focuses on ways in which we gather and process information in order to come up with judgements and explanations for people’s behaviours and personalities or as explained by Fiske & Taylor (1991) â€Å"how the social perceiver uses information to arrive at casual explanations for events.It examines what information is gathered and how it’s combined to form casual judgements†. There have been many studies aimed at explaining the main errors people make when making inferences about people’s behaviour and whether culture has an effect on how we make attributions. There are two types of attributions, internal attributions, also known as dispositional attributions, are when we attribute behaviour to person’s disposition (ment al state, personality, emotions, characteristics, etc. ).External attributions (also known as situational attributions) can be explained as attributing behaviour to the situation or the environment in which the behaviour took place. Correspondent inference (Jones & Davis, 1965) can be explained as when the observer infers that the actor’s behaviour corresponds with their motives (an internal attribution). A correspondence bias is when the observer over-attributes the cause of behaviour to dispositional factors at the expense of situational antecedents.This can also be explained as the fundamental attribution error (Lee Ross, 1977). Another believed to be error in attribution is suppressing dispositional inferences during social judgement, which leads to the dispositional rebound (Geeraert & Yzerbyt, 2007), meaning relying on dispositional inferences in subsequent judgements. It is believed that a judgement begins with a dispositional bias and situational information is to cor rect the initial judgement (Quattrone, 1992), this is called situational correction.Geeraert & Yzerbyt state that the observer must suppress dispositional judgements during the correctional stage and deal with the dispositional rebound in subsequent stages. Furthermore, a cause of the FAE (fundamental attribution error) could potentially be the fact that the observer may not see much to gain in making the effort to analyse the situational causes of a certain behaviour and too cognitively demanding (Andrews, 2001).However, due to the fact that they have greater incentives to predict and influence behaviour, people who tend to depend on others are less likely to make erroneous attributions, which explains why people from more interdependent cultures (such as East Asians) tend to avoid the FAE (Choi et al, 1999) in contrast with people from more independent cultures (such as Europeans or Americans).To further elaborate on this point, numerous psychologists believe that culture may have a determining effect on whether the observer is prone to excessively relying on dispositional judgements. This is shown in Choi & Nisbett’s 1998 study, which was in line with Snyder & Jones’ 1974 study, where a group of Korean and American participants were given the task of writing an essay with a designated position.They were then asked to judge a forced writer (a writer which wrote a piece as a forced task, whether or not what they were writing reflected their own beliefs). In contrast with the previous study, the Americans’ judgements were not affected, however, the Koreans no longer displayed correspondence bias when the situational forces were made salient. Kitayama and Miyamoto carries out a similar study, including Japanese and American students and as predicted, the Americans displayed correspondence bias, while the Japanese students did not.Moreover, with the aim of discovering whether the dispositional rebound occurs amongst people of East Asian back ground and using the dispositional rebound as a tool to study the process of attribution, a study was carried out which participants consisting of 105 students from Hogeschool Gent, Belgium and 128 students from Kasestart University in Bangkok, Thailand, were given the task of judging a free or forced writer in the attitude attribution paradigm. The diagnosticity of the essays were manipulated in order to have participants also judge the essays based on whether they were diagnostic or not.Thai students were more sensitive to the manipulation of the diagnosticity of the essays, whilst the Belgian participants showed no sensitivity at all. Both ethnic groups displayed symptoms of the dispositional rebound when judging a diagnostic forced essay, however, Belgian participants were the only ones to display the dispositional rebound when judging a non-diagnostic essay. Subsequently, participants were asked to judge a series of pictorially represented behaviours. Both Belgian and Thai part icipants displayed the dispositional rebound when the situational information was hidden.However, Thai participants no longer displayed the dispositional rebound when the situational information was made salient (also discovered by Choir & Nisbett in their 1998 study and Miyanoto & Kitayama in their 2002 study). A further explanation of the dispositional rebound could be that it is the ironic consequence of suppression and correction of an initial dispositional judgment as a result of cognitive fatigue due to the fact that the judgment of a constrained target demands a larger amount of cognitive effort which due to the reduction of cognitive resources, leaves some observers to rely on less demanding abstract language.Furthermore, several other studies which have directly focused on the universality of the correspondence bias (Choi & Nisbett, 1998; Kashima, Siegal, Tanaka, & Kashima, 1992; Krull et al. , 1999; Van Boven, Kamada, & Gilovich, 1999) have shown that people from interdepe ndent cultures aren’t immune to erroneous attributions .In these studies, both East Asians and Americans were given the task of judging a constrained target in the context of the attitude attribution paradigm (this requires participants to read an essay which either favours or opposes a particular issue under the conditions that participants are told whether or not the writer had a choice in selecting the viewpoint which the essay reflects), the perceiver induced constraint paradigm (this requires participants to ask a target to read out a pre-written attitudinal statement, then comply observe the target and then try to figure out the target’s true attitude) and the quiz paradigm.The results showed that regardless of culture, all participants displayed correspondence bias. These findings may suggest that culture may not determine whether an observer is prone to erroneous attributions. In conclusion, it seems that the most erroneous method in our ways of making social j udgments is our tendency to rely excessively on dispositional information when doing so and ironically suppressing our dispositional inferences which instinct seems to enforce the occurrence of, seems to cause a rebound effect in subsequent social judgments.But, it also seems that being raised in a society where it is the norm to be dependent on one another, tends to make one naturally more sensitive to informational information when it is there to be sensed and therefore more able to make accurate inferences about behaviour and mental states.

Give Me Liberty: Chapter 17 Outline Essay

Populists or people’s party members were part of this era’s greatest political insurgency. It evolved from the Farmers’ Alliance, where farmers across forty-three states banded together to remedy their condition. The people’s party not only attracted farmers but also included all the â€Å"producing classes.† Their lasting legacy comes from the populist platform of 1892 and also from the fact that populism came close to replacing the two already existing parties. Explain how a system of racial segregation was established in the South: Since populism failed in the south, it was open to the induction of a new racial order. As much of Reconstruction was undone as possible by the Redeemers, so called because they believed they saved the region from alleged misgovernment and impending â€Å"black rule.† New laws were created that jailed anyone without a job, and the punishment for petty crimes was increased tenfold. Of course, the black population suffered the greatest after this. Then, convict laboring became popular which basically put blacks right back into slavery. Blacks continued to be denied high paying jobs, but a black middle class began to arise in the urban communities consisting of people with professions such as teachers and professors. Blacks in politics declined also, though not abruptly. They eventually lost their right to vote. In Plessy v. Ferguson it was made legal to segregate public places. Lynching also rose in popular ity again. Describe what ways the boundaries of American freedom grew narrower in this period: At the end of the 19th century, the thought process of Americans changed quite a bit, towards the idea that freedom should not be offered equally, only to the right and supposed deserving people. An Ohio newspaper stated that the influx of immigrants was overrunning cities, and that they â€Å"have no appreciation of the true meaning of liberty.† Most of the immigrants in this period came from Italy, Russia, Austro-Hungarian empires, and other countries in Southern and eastern Europe. Immigrants were looked down upon as horrible excuses for people who are inclined to steal and commit crime from birth. People started to look for a way to limit the rights of these people, and also prevent more from entering. In Boston, the immigration restriction league was formed and proposed that literacy would be required to enter the country. This was adopted by many states. Blacks also continued to see less and less rights in the South, as well as disenfranchisement. Suffrage was becoming more of a privilege in America, instead of a right. Explain how the United States emerged as an imperial power in the 1890’s: America started out slow as government officials and business owners decided the land and resources they had weren’t enough. At first, proposals to annex other countries were vetoed and over-sea focus remained mostly on trade. Then, a group of late nineteenth century thinkers proposed an idea of updated manifest destiny, and that the most beneficial thing to do for the world was to impose the Anglo-Saxon traditions on uncivilized societies and turn them into consumers of American goods. This was outlined in the book Our Country by Josiah Strong. Alfred T. Mahan took advantage of the time at which western expansion ended, as all land was finally claimed by a state. He published a book that urged American expansion to move outward because we could no longer capitalize on our own land. This book influenced James Blaine, secretary of state during the presidency of Harrison. Harrison requested the construction of four new battleships, while Blaine encouraged the president to push for Hawaii, Puerto Rico, and Cuba to be set up as naval bases. The depression further exacerbated these ideas and plunged the country into a period of aggressive nationalism, where newspapers containing sentiments of nationalism views sold like hotcakes. Vocabulary: The Farmer’s Alliance – Farmer’s in the early 1890’s felt disenfranchised, so they banded together to aid each other. Spread across 43 states. The Populist Party – Evolved from the farmer’s alliance, except it included all working classes. Their platform still remains a classic American document. They sought to redefine the idea of freedom in the contemporary government. It attracted many followers, including a large number of women who wanted suffrage, and a small number of blacks. Populist Platform – Consisted of six main items: 1. Direct election of U.S. Senators 2. Government control of currency 3. A graduated income tax 4. Low cost public financing for farmers 5. Legalize unionizing 6. Public ownership of railroads William J. Bryan –Second candidate chosen by populists for president. He was supported by democrats as well and ran as democrat even. He condemned the gold standard, and advocated free silver and unrestricted minting of silver money. He hoped it would help relieve farmer debts. He was also devoutly religious. Coxey’s Army – A band of several hundred unemployed men led by Ohio businessman Jacob Coxey demanding economic relief. They marched to D.C. where they were forced to disperse by soldiers. Pullman Strike – Workers in a company owned town called Pullman called a strike due to low wages. The idea spread and the boycott called by the American Railway Union crippled national rail service, government injunctions were imposed to force laborers to work. Eugene V. Debs – Charismatic leader of the rail-worker’s union and the Pullman strike, was jailed for contempt of court. On his release, 100,000 people greeted him, and he called them lovers of liberty. He said that state and national government was going to take from the weak their birthright of freedom. Free Silver – Unrestricted minting of silver money, Supported by Bryan because he hoped to circulate more money to aid farmers. Election of 1896 – Won by William McKinley, the republican candidate. Bryan who represented the democrats lost by about 6 million votes. Bryan is noted to have driven many republicans to McKinley because of Bryan’s call for inflation and speeches against corporate arrogance. Northeast and Midwest industrial states voted republican, while less populous states voted for Bryan which is why he lost. William McKinley – Former Ohio governor and republican, won the election of 1896. His campaign manager Hanna created a political machine that flooded the states with pamphlets and other propaganda. The Redeemers – Claimed to have redeemed the southern region of misgovernment and black rule. They were able to impose their racial order due to the failure of populism in the south. When they gained power they quickly undid as much as they were able of Reconstruction. New laws incarcerated people for the simplest of crimes, and then convicts were bought and sold and used as a cheap form of labor, much like slavery. The Kansas Exodus – 50,000 blacks migrated to Kansas in the belief they would find political equality, freedom from violence, access to education and economic opportunity. Pap singleton handed out flyers portraying Kansas as a utopia. However, most blacks didn’t have the capital to farm so they ended up getting stuck there with low paying jobs. Decline of Black Politics and voting – Black people gave up their interest in politics after reconstruction, and they sought more fulfilling careers in business, law, or the church. This turned out to be their worst mistake because then their voting was taken away in the south as soon as it was possible. Poll taxes and other voter restrictions were enacted that were aimed at blacks but still lawful. Jim Crow Laws – State and local laws mandating de jure racial segregation in Southern states. Examples: Created the poll taxes, literacy tests, and the grandfather clause. Blacks were denied access to many public and municipal facilities such as parks, theaters, housing, and mass transit. Various economic sanctions were placed on blacks in order to maintain their status. Plessy V. Ferguson – Upheld the constitutionality of state laws requiring racial segregation in public facilities under the doctrine of â€Å"separate but equal.† Lynching – The murder of a person, usually black, and then hanging them on a tree to ridicule them. Authorities seldom involved themselves in the conflicts even though they knew about them. Chinese Exclusion Act – The first major legal restriction on immigration to the U.S.; prohibited further unskilled Chinese immigration in order to reduce competition for jobs. Booker T. Washington – Former slave who promoted economic independence and a slow transition for blacks into free society; founded the Tuskegee Institute. American Federation of Labor – Alliance of skilled workers in craft unions; focus was bread-and butter issues such as higher wages, shorter hours, and better working conditions. It was led by Samuel Gompers. Alfred Mahan – Author who argued in 1890 that the economic future of the United States rested on new overseas markets protected by a larger navy; wrote â€Å"The Influence of Sea Power Upon History.† Josiah Strong – Author of Our Country: Its Possible Future and Its Present Crisis, in which he urged Anglo-Saxons to â€Å"civilize and Christianize† the American West. Annexation of Hawaii – American sugar plantation owners began the annexation by overthrowing the country’s queen successfully, which was followed by American military action. McKinley requested a joint resolution of annexation because it was popular amongst Americans although not among Hawaiians. Spanish – American War – Caused by suspicions of the Maine, support of Cuban independence, economic depression, and Yellow Press Journalism. The effect it had on America was that it pushed it into imperialism, after the war was won by the U.S., they received three new territories. Teller Amendment – Promised that America would not annex Cuba after winning the war. Yellow Journalism – Journalism that exploits, distorts, or exaggerates the news to create sensations and attract readers. Open Door Policy – Allowed free flow of trade with Asia, while still barring Asians to enter the country. The Philippine War – Began after Filipinos incorrectly thought that they would self govern after independence from Spain. McKinley decided he still wanted the islands though, so they revolted and lost. â€Å"White Man’s Burden† – Poem by Rudyard Kipling outlining the contemporary thoughts of the government, which is it is our duty to civilize the lesser races. Anti – Imperialist League – Argued that an empire and democracy cannot coexist.

Case Study Analysis †Chapter 6 Essay Example

Case Study Analysis – Chapter 6 Essay Example Case Study Analysis – Chapter 6 Essay Case Study Analysis – Chapter 6 Essay Case Study Analysis – Chapter 6 Name: Institution: Date: Case Study Analysis – Chapter 6 This chapter deals with the need for healthcare professionals to monitor and police themselves, to ensure that they are following the ethical policies and procedures they have established. The chapter highlights some of the reasons that cause ethical problems within health institutions, and among healthcare professionals. It looks at the role that health institutions and health professionals have in maintaining quality in the provision of healthcare. It deals with the issue of whistle blowers, who often come from among the professionals. The chapter identifies ways that a person can go about solving an ethical problem, before resulting to denouncing the issue publicly. Hospitals should formulate policies that will take care of the health professionals working at the institution by ensuring that they do not have to work under unfavorable and compromising conditions, while at the same time protect the mission of the institution The chapter highlights and discusses some ethical problem s. Healthcare institutions have to make difficult decisions in the course of their operations. They have to ensure that they provide affordable healthcare, remain profitable, compete with others in the market, and at the same time ensure that they provide quality healthcare to the patients. This can present ethical problems, as the professionals strive to create a balance. Another ethical problem is that the board or the hospital administrators have to find the right ways of dealing with professionals who have ethical problems, yet these professionals have a lot of influence to the organization. The other ethical problem presented concerns the issue of staffing. In an aim to reduce costs in the hospital, the administrators may sometimes feel the need of employing unlicensed personnel to the posts of nurses, and they will fire registered nurses. The registered nurses earn more than the unlicensed nurses do. When the administration takes such an action, it will mean that the registere d nurse may have to take on the responsibility of being a supervisor, to people who are not qualified for the position. Mrs. Lewis acted correctly when she reported the matter. She gathered the evidence required to present her case, before making her allegations. This particular case did not require her to follow any chain of command, since she was not dealing with issues related to her hospital directly. She followed the requirements of the state laws, which were to report any such incidences to the Welfare Bureau of Inspection. Had Mrs. Lewis not been able to afford a lawyer, she would have gone through the chain of command, and in this case, she would have talked to the director of nursing and told her about the situation with the administrator. Together, they would have found a solution to their problem. Whistle blowers can protect themselves by being anonymous. Power is an important consideration when dealing with health care ethics. Many health care institutions are concerned with ensuring that they remain reputable within the industry. Because of this, they appoint different boards to deal with emerging problems at the hospitals. They expect a person with a complaint to take it to the relevant people in the hospital, and deal with the problem in-house, ensuring that the institution retains its image. The various boards have the power to deal with these problems before they escalate and cause other problems to the institutions. The motive that the whistle blower has can change the nature of whistle blowing. Some people might decide to denounce an institution or a colleague publicly, without consulting or reporting the matter to the relevant people in the institution. This may be as a way of seeking revenge for something, or as a way of seeking financial compensation. The whistle blower might not even be interested in the patients’ conditions. I do not think that 10% is a fair reward, considering the risks that the whistle blower is taking. By blow ing the whistle, the accuser faces the risk of retaliation, which may come from the accused or his or her colleagues. The colleagues may shun the accusers and scorn them. They may treat the accusers with indifferences since they feel that the accusers have betrayed them. The administration may also retaliate in terms of creating unfavorable conditions for the accuser to work, such as giving the accuser tough working shifts. In addition, the accuser may face countercharges, and he or she ends up using a lot of money in defense. Response to part 3 Many nurses would like to act ethically, and they would want to report incidences of illegal practices. The nurses should be confident in their employers, and they should trust them to make the right decision. They can make their case stronger, if they had the means to gather evidence, which they can then present to the board, their employers, and any other relevant authorities. Many people want to act ethically, and only a few people are involved in unethical practices. The more many people are aware of the illegal practices in the institution, the more the board or the governing body of the institution will be forced to act on the cases. Reference: Garrett, T.

Make Mood Ring Color Change Slime

Make Mood Ring Color Change Slime Combine mood ring science and slime in this fun and easy color change chemistry project. This is thermochromic slime, which means its slime that changes colors according to temperature. Its simple to make. Color Change Slime Ingredients You can add thermochromic pigment to any of the slime recipes, so feel free to experiment. Heres how to make temperature-sensitive slime using the classic recipe: 1/4 cup white school glue (or use the transparent kind for see-through slime)1 tablespoon water3 teaspoons thermochromic pigment (find at Amazon)1/4 cup liquid starch (find at Amazon)food coloring  (optional) Youll notice thermochromic pigment tends to go from one color to a second color (e.g., blue to yellow or red to green), rather than display a whole rainbow of colors like a mood ring. You can expand the color possibilities of the slime by adding food coloring. This will give the slime a base color and will alter the appearance of the color change pigment.   Make Heat Sensitive Slime Stir together the glue and water.Sprinkle the thermochromic pigment over the mixture and stir it in. This is to help avoid clumps.Mix in food coloring, if desired.Add the liquid starch. You can stir it in, but this is the fun part, so feel free to use your hands to make the slime!  Discard any leftover liquid. When youre not playing with it, store the slime in a plastic baggie or sealed container. You can put it in the refrigerator if you plan on keeping it a long time, to discourage mold from forming. Also refrigerating the slime is a good way to get it to change color after youve warmed it with your hands.Clean up slime using warm water. If you use food coloring, remember it can stain hands and surfaces. Tips for Playing with Thermochromic Slime Drape the slime over cold drink containers or hot coffee cups.Heat the slime with a blow dryer. You can add more liquid starch to rehydrate the slime if it starts to dry out.Experiment with the response to hot packs and cold packs.Use a thermometer to see if you can determine what temperature changes the color of the pigment. How Thermochromic Slime Works The slime part of the science project works the same as usual. In the type of slime made using glue and starch or borax, the polyvinyl alcohol from the glue reacts with the borate ion from the borax or starch, forming long chains of molecules that link to each other a polymer. Water fills in the spaces in this network, giving you damp, gooey slime. The heat-sensitive color change relies on leuco dyes. There are  pigment molecules that alter their structure in response to a change in temperature. One conformation reflects/absorbs light one way, while the other conformation reflects/absorbs another way or else appears colorless. Typically these dyes change from one state into another, so you get two colors. Contrast this with liquid crystals found in mood rings, which change color as the space between components of the crystal increases/decreases. Liquid crystals display more colors, but the most common color change liquid crystal composition is inactivated by water, so it wont work with slime.

Factors Influence a Consumer to Select Restaurant in the UK Coursework

Factors Influence a Consumer to Select Restaurant in the UK - Coursework Example Restaurant selection has without any doubt become an established art as of these days. While consumers seemingly exclaim that the quality of prepared food and the type food are the critical variables for restaurant selection or rejection for that question, there might definitely be an overwhelming number of other less significant choice variables.

There is a considerable population in Britain that actually loves to go and eat out in restaurants, cafes, fast food outlets and even bars, taverns, and inns. For some consumers though, it is a leisure activity that usually takes up all of their time and more often than not, their amounts of money too. The specific comportment, in which Britons dine out today, is evermore changing and before we could even start taking into account the ins and outs of modern day restaurant dining, it is important and interesting to u nderstand how the actual practice got underway.
