Quality of US Healthcare Essays - Healthcare Quality, Primary Care

In a country where the health care system is largely provided by the private sector, only 15% of the population has health insurance coverage. A situation that pushes us from the middle/lower social class to wonder about the quality of care we are receiving. The healthcare system is as much controversial as getting the care we need, and how this one is delivered to us. The President of the United States had signed a comprehensive health reform on March 23rd, 2010, the Patient Protection Affordable Care Act (PPACA) which is expected to bring changes to the system, and this act is supposedly bringing a new momentum to the healthcare industry. The American population is actually wondering whether a deep analysis of the future trends on healthcare should give them a clear understanding of where the United States healthcare would be in the next years to come, including improvement on the safety and reliability of the healthcare system. If we were to describe the U.S. healthcare system with all its components, we would have to say that it is a facet of complex interactions of people, institutions, and technology. For many Americans healthcare may be described as the interaction between a primary care physician and patient to address minor and urgent medical problems such as colds, flu, or back pain. A primary care physician (PCP); usually a general practitioner, a family practitioner, internist, or pediatrician, is the ?forefront? caregiver or even the first health qualified personnel to estimate and treat the patient. In a physician office there are lots of routines physical examinations, anticipation such as immunization and health rerun to detect disease, and treatment of acute and chronic diseases. The healthcare system consists of all the medical personnel tied together in one field. This system may be viewed as a complex made up of three interrelated components: people in need of healthcare services called hea lthcare consumers; those who deliver the service, the professionals and practitioners called healthcare providers; and systematic arrangements for delivering healthcarethe public and private agencies that organize, plan, regulate finance, and coordinate servicescalled the institutions or organizations of the healthcare system. This institutional component includes hospitals, clinics, and home-health agencies; the insurance companies and programs that pay for services like Blue Cross/Blue Shield, managed-care plans such as health maintenance organizations, and preferred providers organizations; an entitlement program like Medicaid. Also included are agencies and associations that research and monitor the quality of health care services; license and accreditation providers and institutions; local, state, and national professional societies; and the companies that produce medical technology, equipment, and pharmaceuticals (a href="http://www.libraryindex.com/pages/1817/Nation-s-Health- Care-System-COMPONENTS-HEALTH-CARE-SYSTEM.html">The Nation's Health Care System - The Components Of The Health Care System/a>) Despite the higher cost of our healthcare system, one would think that the service we are providing would be astonishing; we would actually see the improvement of making the hospitalized patients more comfortable in their skin. While the economy is getting tougher, the high cost of living is climbing up the trees; our healthcare system still falls behind other nations in term of quality, access, affordability. Five affluent international trading partners of the United States spend far less on health care, yet the comparative value of these countries' health systems- measured by cost, workforce health, and quality of care- is often better than that experienced by American workers and employers. And that "value gap" puts the United States at a distinct competitive disadvantage to their global peers, according to the Business Roundtable's Health System Value Comparability Study (Anonymous, 2011). Comparing the value of U.S. health care with that of the health systems of the "G-5" countr ies (Canada, France, Germany, Japan, and the United Kingdom), the study finds that our nation has made progress in improving healthcare value over previous years but still trailed the G-5 by 2,0.8 percentage points in 2007. "At the current rate of gap closure, it would take over 20 years for the U.S. health system to pull even with the value delivered by the health systems of the G-5 and an additional 10 years to establish a meaningful lead," the authors say. When comparing our healthcare system to other nations? healthcare organism, we would say the health insurance of certain countries are costs less than

Free Essays on Perception

Outline one direct theory of visual perception: Gibson’s theory: Gibson’s mainly focuses on the idea that perception is a lot more biological and that we directly perceive using an optic array (Information is assumed to consist of signals and to be transmitted from the receptors to the brain). Instead of using the brain to interpret things we use the environment in which perception takes place and the activities of the perceiver within that environment. We then use the affordances (such terrain, water, vegetation, etc.) which provide the clues necessary for perception. However this would eliminate the possibility for the different interpretation and mistakes of visual illusions Using this purely bottom up approach to perception means that all objects in the world have a behavioural ‘significance’ for humans and animals. For example a chair is for sitting on, however the meaning to you of the chair can change according to your mood, if you need to reach for a book the chair is for standing on. Research that could support this idea is Palmer (1975). He showed his group of participant’s scenes that were easily recognisable (for example a kitchen). He would then briefly show them 3 separate images of objects, and ask the participants to identify them. The participants were more likely to choose the image that they perceived to best fit the picture of the familiar scene. It was also found that the first picture of the familiar kitchen scene seemed to prompt the participants to expect an object that you would find in a kitchen. If this research is to support Gibson the participants would have to afforded that the kitchen objects belonged in th e kitchen or the items are used in the kitchen. Also Marr (1982) agrees that there is constant perception in every day life, this is because the world around us is constantly changing.

Assessing health care and needs of older person

Assessing health care and needs of older person Summary Caring for older people with dementia highlights many special and difficult issues for nurses and carers, such as separation, illness, loneliness, death and how to provide continued care (Morrissey et al, 1997, Livingston, 2010). Monitoring and questioning the way we care for people living with Alzheimer’s disease and other forms of dementia is an important part of delivering the very highest standards of specialist dementia care. Aims and Objectives This study is about the assessment of health needs and the strategies of care delivered for an older person with dementia within the community observed during my recent placement. There will be discussions focusing on normal ageing process, taking into account the relevant biological, sociological and physiological perspectives and the impact this had on this individual’s life experience. Dementia Care Mapping and community profile will be introduced. The relevant epidemiology and aetiology factors will be examined and the social and kinship support networks will be identified, how they work together to provide individual holistic patient care, the impact it had on him in the community and finally the impact of current legislation on the overall care provided will be analysed.. The rationale for this is to demonstrate an understanding of the theoretical and practical links in caring for individuals with this condition in the community. Confidentiality is maintained in conjunction with NMC 2010. Thus a pseudonym (Scot) is adopted where the client’s name is mentioned. Context Scot is a 70 year old man with a long term history of psychosis. Recently he had been diagnosed with Alzheimer’s disease, a type of dementia, which affects the brain cells and brain nerve transmitters, which carry instructions around the brain. Scot is also a non-insulin dependent diabetic and has hypertension, both of which are controlled by oral medication. Aeotiology Dementia as a disorder, is manifested b y multiple cognitive defects, such as impaired memory, aphasia, apraxia and a disturbance in occupational or social functioning, Howcroft (2004).The brain shrinks as gasps develops in the temporal lobe and hippocampus. The ability to think, speak, remember and make decisions is interrupted (ADS, 2011). Disturbances in executive functioning are also seen in the loss of the ability to think abstractly, having difficulty performing tasks and the avoidance of situations, which involves processing information. Due to the decline of his mental state, he has been refusing access to his carer (his wife) and was at risk of self-neglect. Current medication He had been well managed on Quetiapine until he had stopped taking the medication and his psychosis had worsened. Quetiapine is an oral antipsychotic drug used for treating schizophrenia and similar disorders. Like other anti-psychotics, it inhibits communication between nerves of the brain. Frequent adverse effects include headache, agitat ion, dizziness, drowsiness, weight gain and stomach upset (Ballard et al 2005). Medical history Seven (7) years ago, he had a mild stroke. He has fractured both of his wrists and has no sensation of the heat or cold on his hands but can move and use his fingers perfectly fine. Referral Scot was referred to the CMHT on the 03 May 2011 by his General Practitioner (GP). He was seen by the CPN for his mental illness and was decided that Scot would be visited every day because of his past medical history.

Evaluate the proposition that the research findings from the use of Essay

Evaluate the proposition that the research findings from the use of animal models has led to new approaches to reduce the effects of ageing in wound healing - Essay Example This might help to identify the targets for novel and effective drug therapy. Normal wound healing is innate host immune response for tissue regeneration and repair involving coagulation, inflammation, epithelialization, formation of granulation tissue and tissue remodeling (Ashcroft et al. 2002). In response to injury stages of wound healing are depicted in figure 1 (Gosain and DiPietro 2004). The number of polypeptide growth factors and cytokines like epidermal growth factor (EGF), basic fibroblast growth factor (ÃŽ ²-FGF), platelet derived growth factor (PDGF) A & B isoforms, the transforming growth factor (TGF-ÃŽ ²), vascular endothelial growth factor (VEGF) plays an important role in wound healing process. It is demonstrated that delayed wound healing in both elderly animal and human individuals is due to decreased inflammatory and proliferative responses, delayed angiogenesis, delayed remodeling and slower reepithelialization (Strigini and Ryan, 1996). Morphology of skin changes with aging process. It involves flattening of the dermo-epidermal junction, disorganized microcirculation, decrease in number of cells as well as dermal cell constituents like fibroblasts, mast cells, macrophages. Also, the morphology, properties and quantity of dermal extracellular matrix content such as collagen, elastin, glucosaminoglycans changes with aging. These variations lead to delayed cellular proliferation, migration, modified binding of growth factor to matrix, alteration in adhesion molecule synthesis and changes in molecular signaling (Ashcroft et al. 2002). These changes affect functional cell response to all the stimuli. The age-related changes in the individual phases of healing are summarize d in Table 1 (Goain and DiPietro 2004). The animal models which are used to study the impact of aging on wound healing are not suitably characterized. Therefore the reported evidences itself are contradictory (Ashcroft et al., 1995).

Platos Analogy of the Cave Essay Example for Free

Platos Analogy of the Cave Essay Plato was a Greek Philosopher, who was a student of Socrates. The Analogy of the Cave in Plato’s Republic was written as a dialogue between Socrates and Plato’s brother Glaucon. In the Analogy of the Cave, Plato describes the prisoners who lived an isolated life in the confined space of a cave. Plato’s Analogy explains a philosopher’s journey to knowledge and the difficulty that he faces along the way and the prisoners in the cave who have not embarked on the journey to true knowledge and are living their lives, only seeing what is on the surface, and what they want to see. The Analogy relates to Plato’s Theory of Forms, which explains how the forms possess the ultimate reality. The World of Forms is the unseen world in which everything is constantly evolving and changing. The Analogy however, is the attempt to enlighten the prisoners and explain the philosophers place in society. He uses the story to explain the need to question everything like a philosopher does in order to distinguish between the unreal, physical world and the real spiritual world lit by the sun. The sun is the ultimate good and Plato gives the name of good the demiurge. The cave is a symbol of the world; it represents the World of Appearances based on what people see by their senses. It is an illusionary physical world in which people are trapped by ignorance and false truths. It is a world where people ignore the truth and are unenlightened. The prisoners are in this illusionary world where they think that what they are seeing is reality however it is not reality at all. In the cave there are shadows of truth and echoes of reality. It is filled with illusions. It is a world of senses where the prisoners have gained empirical knowledge which is flawed. Plato thinks that the prisoners’ situations are no different from ours, as we do not see the forms clearly, only the physical world. Plato believed that everything exists in its true, perfect form outside of the cave in the world of the forms. The Cave; the physical world imprisons a person by stopping them seeing the forms. The cave represents a world where everything comes to an end and will eventually die, however in the world of forms nothing will die or end. Everything is transcendent and evolving. People who leave the cave gain true vision and see reality. The cave can also represent  the body in which our souls (the prisoners) are trapped. Our souls constantly yearn for the World of Forms in which nothing ever decays. The cave may also represent society and the prisoners cannot see the world for what it really is as they are trapped in the claws of society. The prisoners are humans who have a lack of knowledge and are oblivious to the truth and reality. They are in an illusionary world. The prisoners are mankind or at least human thought and existence. They are chained mentally by culture; trapped in society and physically around their necks and feet, which means they are not able to move around. This means that their minds cannot wander elsewhere and they remain fixed on the shadows/their reality. The chains also represent humanities inability to become enlightened and our consciousness. Their reality is the shadows of truth and the echoes of reality. They have never seen true good, true reality; the sun. They represent human beings like us as they are ignorant and oblivious to the truth and the world of forms. Their minds are full of ignorance and false impressions. They have beards which show that they have been there since childhood, and that the darkness is all they know. The prisoners sit facing the wall and have spent their lives watching the shadow play. For them the appearance seems real, as they have never seen anything else. We have sympathy for the prisoners as they have been misguided and are oblivious to the ultimate good; the demiurge. They are people who accept everything at face value and never question or try to understand. Their lives are empty and meaningless. The people who carried the statues helped to shape the prisoners’ views however they also were thought to share the same views as the prisoners. In the ‘Republic’, Plato criticized philosophers and politicians who lead the people but do not actually know the truth. The people carrying the statues are like the philosophers and politicians; oblivious to the World of Forms. The prisoners also represent our souls, which are yearning to get to a higher place. They are trapped inside the body, which is a physical form. The shadows are made from ‘all sorts of vessels and statues and figures of animals’, a mere shadow show orchestrated by the unseen men. They are the shadows which create the false images of distorted truth. They are the limits of reality. The prisoner’s senses are misguided by the shadows. The shadows are deceitful; they are the false way people see things. The shadows that the prisoners look upon represent the perceived truth; the prisoners did not have the knowledge to look beyond the superficial, and only had the capacity to believe in shadows. We are also told about the fire. It burnt behind and above the prisoners. In front of the fire there was a puppet stage for the men to carry the object behind, this would cast the shadows. The only noises the prisoners would hear were the echoes of reality, and the only things the prisoners would see were the shadows of truth. The puppeteers are ignorant for carrying on teaching the prisoners false knowledge. The fire in the cave represents the power of the sun. The fire has the ability to illuminate the false truths inside the cave; it magnifies what the prisoners can see, which shows them what to believe in. The fire represents false and incomplete knowledge and is also deceitful. It represents the illusions that keep us in the dark from truth. The journey out of the cave is the journey to truth and reality; it demands that you must challenge your pre-conceived ideas. The prisoner’s journey out of the cave, his ascent is faced with hardships and struggles; escaping the chains, past the fire and up the steps. The reason the prisoner is described as being ‘dragged out the cave’ is because the journey is distressing and he is being forced out. Plato said ‘The object of knowledge is what exists and its function to know about reality’. It explains how reality is the world of forms and the job of the philosopher is to get knowledge, this is what the prisoner does when he goes out of the cave. He is the one who breaks away and makes the journey out; he is the philosopher who wants to know what is really going on. He wants to see past the distorted truths. ‘And those who strive for reality and knowledge are philosophers’. The escaped prisoner could represent Socrates (Plato’s tutor). The journey out of the cave symbolizes the journey of an average person into the world of knowledge and wisdom through philosophy. This is achieved by looking into the depths of meaning and searching for answers. The journey is uncomfortable as it requires the prisoner to challenge his beliefs. When the prisoner first breaks free he is in tremendous amounts of pain as his muscles have been unused for so long, and he is able to look directly at the fire rather than  just at the shadows. The path outside the cave is rocky, steep and unstable as the things that the prisoners once knew as reality are all becoming unclear. Once the prisoner is out of the cave, he is faced with the sun. The sun represents complete knowledge, wisdom and enlightenment. It represents the World of Forms, which the soul yearns to reach. It represents the ultimate good, the ideas/forms; the demiurge. It reveals the world to the prisoner, and how things can be if you come out of the shadows. It represents truth, beauty and justice. When the prisoner see’s the sun, he becomes temporarily blind; this represents the enlightenment because he has discovered a world past the shadows. A world which is real. The sun lets him see the true beauty of things, not the shadows that he saw before. Plato suggests that in this world, the sun gives both life to being as without light, we and the plants and animals would not grow and flourish, and provides light by which these things can be seen. The sun is the source of truth and reason; it represents the perfection of realities. Through the sun we will see the truth, real beauty and real justice. He comes to see a deeper reality, a reality marked by reason. Once the prisoner has embraced his new found knowledge, he wants to maintain it and no longer live a life of confinement trapped inside a cave. Once he sees reality, he makes a painful readjustment back into the darkness of the cave. This journey back is also painful as once he has seen reality, he does not wish to reminisce in the deceit of the past. However he is a good man, who gains true knowledge and wishes to enlighten the others. He could represent Socrates going to enlighten Athenian Society. When he gets to the prisoners, he seems mad, as he describes a new strange reality. They laugh at him and mock him, and reject him to the point of threatening to kill him. Their disagree shows how previous philosophers such as Socrates were penalized and laughed at for their beliefs and ultimately killed. Plato’s Analogy of the Cave is a representation of the human condition, under the circumstances of our basic beliefs and behaviors in society. It represents the lack of human knowledge, and the difference between the two  worlds. It shows that in the World of Appearances, everything we see or experience are shadows of The World of Forms, they are impure. They show that we live in a world full of flux and decay and we are just matter. The World of Appearances is a Visible World and a Finite World whereas The World of Forms is an Unseen World, full of phenomenons, forms and ideals. The World of Forms is constantly evolving and changing; ‘You cannot step into the same river twice’. The World of Forms is outside the cave, and it is where everyone aims to go. The soul yearns for a higher place.

My Antonia Essay: Weak Structure and Powerful Drama :: My Antonia Essays

Weak Structure and Powerful Drama in My Antonia Much of the earliest criticism of My Antonia focuses on the apparent failure of the narrative. Many critics take the title of the story and its introduction at face value. When the story says it is to be about à ntonia, it must be about her! Therefore, many critics see the stunningly crafted pieces of "variation from a theme" -- the stories of Peter & Pavel (the Russians and their wolves) and the sections of the novel dealing with the hired girls Lena Lingard and others-- as divergences which weaken the overall structure of the novel. In other words, these stories distract us from the real story, that of à ntonia and her relationship with Jim. Other critics talk mostly about the landscape of Cather's stories, the way the pioneer story and the struggle with nature is a vital piece of her work. This is partly why, I think, Cather has been viewed as a minor writer of "local color" for so long. Because she sketches her landscapes with such simplicity and yet detail, many critics do n ot look past the landscape to see the characters and the true drama that they play out.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  An example of a critique which accepts the critical opinion that the novel is "defective in structure" is James E. Miller's 1958 essay "My à ntonia: A Frontier Drama of Time." I group his essay here because he spends the bulk of the essay arguing that the defect of structure is overcome when we look at the cyclical nature of time in the novel as its unifying theme. This article does seem to be one of the first ones that looks to disprove the "failure" of Cather's narration. Of course, by disproving this argument, Miller is still working within the context of failure/success which I don't think other writers (read male authors) are judged by.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Miller begins his argument by pointing out that many critics "have felt the unified emotional impact of My à ntonia and have grappled with the puzzling problem of the book's actual lack of consistent central action or unbroken character portrayal" (Miller 52). Miller argues that there seems to be no consistent character portrayal, "The action in My à ntonia is episodic, lacks focus and abounds in irrelevancies"(Miller 52). But Miller believes that there is a consistency within the novel, that of the evocation of feelings which the reader has.

Slope of the graph = Ea / 2. 303R Ea / 2. 303R = (1. 462-0. 903)(0. 003472-0. 003145) Ea / 2. 303R = 0. 559/(3. 27Ãâ€"10-4) Ea = 1709. 48 x 2. 303R Ea = 1709. 48 x 2. 303 x 8. 314 Ea = 32731. 65 J/mol Discussion Precautions Among some of the precautions taken were to wear gloves , safety goggles and lab coats to avoid any injury in case of exposure to chemicals.Secondly, there were separate measuring cylinders prepared for each solution as to not mix 2 solutions in a measuring cylinder to avoid any reactions. The persulphate was poured in rapidly as this is an extremely fast step and has to be poured all at once. Finally,when diluting the persulphate solution, it was done as accurately as possible in order to avoid a wrong concentration instead of the one intended. Conclusion Based on the experiment done as well as the analysis of the results and after doing further results, we have learned that the activation energy of the reaction is 32. 73 kJ.Furthermore, we have gained an insight into the kineti cs of a reaction, its rate, the rate constants as well as the rate of reaction.

Economic and Political Changes During the Medieval Ages Essay

Before becoming what it is today Europe went through a lot of changes. After the fall of Rome, Europe was in chaos. This is until Charlemagne helped to restore it, after his death though, Europe was back into chaos. Chaos ended in the High Middle Ages when Europe prospered politically and economically. In the Early Middle Ages, also known as the â€Å"Dark ages† which was after the fall of Rome which was caused because of lack of a centralized government, lack of trade, and lack of formal learning, there was a period of great disorder. Because of Europe’s many natural resources such as their seas which were great for fighting and farming, many Germanic tribes, Viking, and other people tried to attack it. When Charlemagne became Emperor the chaos stopped but after his death it continued again. The High Middle Ages were times of economic and political prosperity for Europe. Europe started using a feudal system, which is a system of government based on control of land. In feudal society everybody had a place. For example, vassals pledged their loyalty to their lords and they helped each other out. Another example is serfs farmed and did other labor work for the lords and kings in exchange for land and food. The feudal system provided Europe with a centralized government. Economically Europe also changed, During the Agricultural Revolution they made new technologies such as the wind mill and iron plow which greatly helped with farming. They also started using the three-field system. Because of their change there was more food and the population grew. Trade routes, trade fairs and towns were also created. Another big change was the Commercial Revolution. Money reappeared and was used to buy and sell goods. Europeans developed new ways of doing business. They created partnerships and an insurance system. This greatly helped business in Europe. In order for Europe to get out of its â€Å"Dark Ages† it had to go through change. By changing politically and economically, it prospered. Even now other civilizations are influenced by this. For example we have an insurance system and use windmills. In order for Europe to prosper it had to go through change.

Rome continuation of Greek civ essays

Rome continuation of Greek civ essays To what extent was Rome simply a continuation of Greek civilization? To what extent did Rome innovate in Mediterranean civilization? The classical civilization of Greece contributed in the rise of the second largest Mediterranean city: Rome. The role of the past Greek civilization influenced Rome greatly, providing a knowingly functional set of essential and core ideas which could be expanded and built on by the Romans. Such essential and core ideas between Greece and Rome remained the same throughout Romes expansion; ideas, simultaneously, stemmed from familiarities, while expanding and focusing on completely different aspects. Art and philosophy of the Greeks serve as and represent its most lasting classical civilization attribute. Later Romans derived much from Greek art and philosophy, while keeping and modifying particular aspects. Greek and Roman religion-with similarity of gods, differing mainly in their names-contributed to artistic disputes within Roman upper-class life concerning Roman values. Authors and sculptors of Rome often times copied Greek work by modifying characters in stories and heroic statues. Science also expanded with few Roman additions, differing greatly from the additions of their architectual advances leading to powerful and detailed structures such as public baths, large stadiums and water aqueducts. Differences in Greek emphasis of science and philosophy and Roman emphasis of engineering and law led to the formation of Romes principles of politics. Laws were generally based on common sense and protection of the family and private property. This law expanded as the Romans did, demanding compliance and citizenship (idea Greeks opposed) among conquered groups allowing them to be preserved(p159), ultimately contributing to the greater preservation of Greco-Roman beliefs. Social structures of Greece influenced Romans. Aristocrats, merchants, peasants, and proper...

European colonialism is often depicted as a force of greed that Essay

European colonialism is often depicted as a force of greed that exploited the African people for financial gain however, one cou - Essay Example Europeans used guns and bombs. This was described as spiritual or religious war, as the Africans hoped for immunity from the bullets, offered to them by their gods. However, the evils of the war have been discussed over and over, with little focus on the benefits the war had on Africans and the Europeans. This paper seeks to find out the benefits of the war to both Africans and Europeans, especially through moral changes. As earlier noted, Africans used bows and arrows, swords and shields to wage their war against the American soldiers. However, during the progressive days of the war, they adopted the Europeans style of fighting, and embraced the use of guns and bullets. Although these arms were not legally acquired as the African militants staged ambush on the American army and stole away their guns and ammunition, they helped improve their fight against the American soldiers significantly. The realization that their forms of fighting could not be comparable to that of the Americans quashed their naivety and they started embracing the importance of modernized forms of fighting. To this modern day, the Africans import guns and ammunition for war and internal security. The African disorganized form of fighting always gave advantage to the Europeans soldiers. They did have any form of training in fighting skills. This made the European army to have an advantage over the Africans. With time, they learnt the art of organized fight which greatly improved in their fighting tactics. At times they surprise that Americans soldiers and won in a number of battles. Most of the African and European gains from colonization were long term. Various changes were experienced by Africans, but also enjoyed by the Europeans. Effects of colonialism are felt in the African continent even to this day, years after the rule ended and the continent became independent. The Europeans gained economically through the raw materials that they acquired from Africa. The Europeans borrowed the sh ield used by the Africans in the war to form a basis for a number of games played by the Europeans. Some of the African games were adopted by the Europeans with minimal changes to suit the European children. Other games played by the European children based their ideas from the African games. Although most of the Africans consider the colonial rule to have been bad, evidence shows that they benefited handsomely from the rule. Some countries that were not been colonized when they lagged behind other countries that had undergone the colonial rule, they attributed this to the lack of the colonial rule in their country. An example is Ethiopia, a country that was not colonized by and foreign power. Emperor Haile Selassie declared that at one time, the county was too poor because it had not experienced the colonial rule like its African counterparts. For example, most of the Africans before the colonial era were culturists. They did not have a formal religion and mostly thought that their gods lived in the forests, in caves or in the mountains. However, with colonization, Europeans brought religion to the Africans. They taught them the values of Christianity and the importance of the bible. The Europeans introduced Christianity to the Africans, and thus changed their way of life and understanding of Christianity. Many at times, the Africans would offer rituals and sacrifices to their gods, but when the Europeans

Keeler v. Superior Court, 2 Cal 3D 619 (1970) Research Paper

Keeler v. Superior Court, 2 Cal 3D 619 (1970) - Research Paper Example He insisted, upon viewing her pregnant form, the he would â€Å"stomp it out of you†, then pushing her against the car and driving his knee sharply into her abdomen (New York State Bar Association, 2010, p.623). After striking his wife in the face several times, she eventually fainted. Upon awaking, Robert Keeler had left the scene of the crime. Her first move was to return to Stockton where she approached the police, who summoned medical assistance. She was discovered to have significant facial injuries and extensive bruises on her abdomen (loislaw.com, 2010). Upon the advice of medical practitioners, a C-section was performed in which the fetus was discovered to have a fractured skull and was delivered stillborn. Under Penal Code  § 187, Robert Keeler was charged with murder as it was determined that the damage caused to the fetus could only have been sustained through external force. The Supreme Court of Amador County ruled that Robert Keeler could not be held on murder charges or convicted of the crime. The judge in the case cited Penal Code 187 that provides â€Å"murder is the unlawful killing of a human being, with malice afterthought† (loislaw.com, 2010, p.2). At this time, in 1970, most of the laws pertaining to murder and identifying what constitutes a human being was related to very old common law from the 1850s. There were no precedents set that clearly indicated fetus rights and such rights in relation to classification as a human being. This common law involved protections for individuals who had been born alive, and Teresa Keeler’s child had been stillborn. The judge had no legal viability by which to uphold murder charges. The judge further ruled that citing other relevant laws other than those spelled out in Penal Code 187 would deny Mr. Keeler due process afforded him by law (loislaw.com). Though Robert Keeler’s domestic assault charges were upheld, there were absolutely no
