LAW CASE (sheapard v. united states) Study Example | Topics and Well Written Essays - 500 words

LAW (sheapard v. united states) - Case Study Example In 1933 Major Shepard files a Petition for a Writ of Certiorari. A Writ of Certiorari is a document in which the losing party files with the Supreme Court asking them to review the case from a lower court (Techlaw Journal, 2008). This can be done when the petitioner is dissatisfied with the decisions of the lower courts including the US Court of Appeals. A Writ can be granted at the discretion of the US Supreme Court. The Supreme Court being the highest Court in the Nation has the right to not accept the petition and there has to be some kind of compelling reason for acceptance. In Shepards Case the Writ of Certiorari was granted. US Supreme Court Judge Cardozo reveals to the court that circumstantial evidence was used to prove to the jury the Major Shepard was guilty. According to the judge a conversation with Mrs. Shepards nurse Clara Brown, Mrs. Shepard asked the nurse to find her a bottle of whiskey. She then asked the nurse if there was enough left to prove the existence of poison. The nurse then states that the Mrs. Shepard accuses her husband of poisoning her. The Judge then states "The admission of this declaration, if erroneous, was more than unsubstantial error. As to that the parties are agreed. The voice of the dead wife was heard in accusation of her husband, and the accusation was accepted as evidence of guilt.

Assignment – Week 3 – Esposito-Hilder vs. SFX case Essay 1) What is the most â€Å"jealousy† protected kind of speech, according to the court in this case? (3 points) Answer: According to the court in this case, the most jealousy protected speech is that which advances the free, uninhibited flow of ideas and opinions on matters of public interest and concern. That which is addressed to matters of private concern, or focuses upon persons who are not â€Å"public figures† is less stringently protected. 2) What court decided the case in the assignment? (2 points) Answer: Supreme Court of New York 3) Briefly – state the facts of this case, using the information found in the case in LexisNexis. (5 points) Answer: In this case, radio station and disc jockeys (defendants) challenged the judgment of the Supreme Court of New York, which denied their motion to dismiss the plaintiff private individual complaint for failure to state a cause of action in her action alleging intentional infliction of emotional distress. According to the information provided in this case, the plaintiff private individual bridal photograph was published in a local newspaper along with those of other brides. The same day, during a broadcast, the defendants engaged in a routine known as the â€Å"ugliest bride† contest. During this contest, they made derogatory and disparaging comments about plaintiff’s appearance. The plaintiff alleged that the defendants deviated from the regular routine of the contest by disclosing her full name that she worked as a competing radio station, as well as the identity of, and her relations with, her superiors. The plaintiff alleged that she and her supervisors heard this broadcast and as a result of its offensive content, she experienced extreme emotional distress at the time because she was a newlywed. Additionally, the court affirmed the judgment of trial court, which denied the defendants’ motion to dismiss the plaintiff’s complaint and found that the plaintiff had an actionable claim. 4) According to the case, why was this not defamation, and what tort did the court approve a filing for? (5 points) Answer: According to the case, this was not defamation due to the reason of being an expression of opinion. Due to the unique factual information presented in this case that the plaintiff was a private individual and the matter was not of public interest or concern, the court approved a filing for the plaintiff’s lawsuit of the intentional infliction of emotional distress to proceed. 5) In the decision, why does the court state further proceedings will be required? (5 po ints) Answer: The court states that further proceedings will be required because more investigation needs to be done into the plaintiff’s allegations to determine what extent the allegations of her complaint ultimately satisfies the stringent requirements for the tort and sufficiently states a cause of action for intentional infliction of emotional distress. 6) Do you agree with this decision? Why or why not? (5 points) Answer: This student agrees with this decision because even though there was a contest, there was no reason to disclose the plaintiff’s personal information and details of her job and make disparaging and derogatory comments about her appearance. Her personal information was revealed during the broadcast and therefore one could identify her and due to these facts the plaintiff could experience emotional distress, especially since she was a newlywed.

The Dark Side Of The Nation Cultural Studies Essay

The Dark Side Of The Nation Cultural Studies Essay This paper chooses two articles namely Indian Country: Essays on Contemporary Native Culture by Valaskakis and Himani Bannerjis The Dark Side, of the Nation: Essays on Multiculturalism, Nationalism and Gender, to try and compare and contrast the theoretical approach that the authors of the two articles have used. In the first article Indian Country: Essays on Contemporary Native Culture, by Valaskakis, the author uses a cultural studies approach to present a distinctive view on Native cultural conflict and political struggle both in the United States and Canada. She reflects on traditionalism and treaty rights, Indian princesses, museums, art, powwow, media warriors and nationhood. Writing on Land in Native America by Valaskakis, the author depicts the Indian Country as concurrently evoking collective experience, a sacred space and physical land in which the individual interacts within these dominions. In the second article The Dark Side, of the Nation: Essays on Multiculturalism, Nationalism and Gender, by Himani Bannerji, she presents an anti-racist, feminist, Marxist assessment of multiculturalism as a means for the white Canadian select few to oppress immigrants, whites, non-whites, women, and other minorities. She notes how the selected few use constructions like community and culture to dominate while hiding at the back of the liberal-democratic nuances of multiculturalism. In the Valaskakis essay, The Paradox of Diversity, the author notes how the language of multiculturalism (i.e. women of color, visible minority) restrains nonwhite persons. The difficulty is not that such identifiers be present, but that they indicate a need to manage and control non-white Canadians. The contradiction is that multicultural language serves the objective of Whites to track ethnicity and race rather than the interest of noticeable minorities. The authors of these narratives are trying to defi ne what indigenous thought is by putting forward extensive arguments based on the various societies each has focused on. In this paper, we try to explore on each authors point of view with an aim of getting a clear meaning of indigenous thought. Both authors have critically approached their argument and have presented it in a clear and flowing manner that has assisted in the effective construct of the authors theories as well as their overall thought process in the paper. The most basic idea in both the papers is the presentation of the indigenous thought and the critical race theory. The indigenous thought: So what do I mean when I talk about Indigenous thought? First, let us start with what indigenous thought is not: Indigenous thought is not the self-serving and naive idea that anybody who digs his or her hands in the dirt has indigenous understanding. I am referring to the modern-day knowledge that arises from countless generations of people living in relation to a particular land and seeing it as the foundation of all their relations. By land, I reach further than any simple material idea to the emotional, intellectual and spiritual dimensions thereof. Land includes streams and rivers, wind and air as living beings in our existence. Indigenous thought is founded in a profound understanding that we all exist in relation to land. Whether we are dwellers of the city in deep denial or Aboriginal people drawing on old customs to regenerate new awareness, we exist in relation to land. We bundle up when the snow comes, we protest when spring is delayed, we breathe deeply and refurbish our souls when the sun warms us into a new season. For an effective statement on Indigenous thought, I draw on the writing of Valaskakis, Gail Guthrie in her essay Claiming Land in Native America. She argues that land is hardly ever understood as a discursive place of Indian experience imagined, lived and remembered and an enduring place of Native political possibility. According to Valaskakis, the continuing contests that yarn through the connotation of constructed representations and endorsed ideologies of Native people and other North Americans involve underlying issues and images of land in Canada and the United States: continental territory- privatized, settled, developed, explored, reserved, mapped, idealized, imagined and contested. According to Valaskakis, the Native claim to recognize rights to the land is a lawful move to resolve the wrongs of the past; but to Native people, land claims have at all times represented more than territorial access to resources and expansion. The Natives claim that the land belongs to them, for the Great Spirit gave it to them when he put them there. The Natives believe land to be their ancestral right and this gives them the rightful ownership of the land since their fore fathers found the land and settled in it before anyone else. The Natives say they were free to come and leave and to exist in their own way and they were free to practice whatever it was that they believed in. However or rather unfortunately, the white men who belonged to another land, came upon them, and forced them to live according to their ideas and practices. The political struggle over land is covered in a complex of contradictory representations, different cultural constructions and oppositional discours es. For example, when we look at the Cree dispute over the extension of hydroelectric projects in Northern Quebec, the interwoven discussions that disclose native and nonnative relationships to the land are both essential and complex. It is a struggle that has unraveled a complex braid of conflict between radically different knowledge systems and representations about the land and territory, progress and survivability, rights and justice- the latter two couplets hitched to differing commitments of nationhood and its attendant cultural and political desires(Valaskakis 90). According to Valaskakis, in the combined heritage of struggle and resettlement of reservations, land allotments and resource exploitation, the meaning of land that comes out in the lived understanding of present practice of Native people is interwoven with images of enduring indigence, forced acculturation and painful displacement. Land is essential in the modern-day culture of Native America; and today, its meanin g is discussed in the discursive building of emerging heritage, contingent history and modern practice in the stories Native people tell that convey empowerment linked in expression to Native political struggle and traditional practice with nonnative and with one another. Today, the Native sense of unity is an idiom of collectivity that goes beyond place-centered society to the oneness of pan-Indianism. As new formations of Native community emerge in the academic, professional, social and urban areas of Indian Country, Native identity and culture are recreated in narratives of past practices and places, transformed and experienced today in pan-Indian rhetoric and rituals. These are not the homesick words of cultural tourists or the heartbreaking pleas of homeless migrants who are removed or displaced from their cultural or territorial roots, but the voices of Native North Americans who identify home in the emergent re-territorialized creations of Indian Country. These stories that reclaim place and people, reconfigure land as terrain, terrain that represents not only communal, spiritual experience but also familiar colonial experience. What makes us one people is the common legacy of colonialism and Diaspora. Central to that history is our necessary, political, and in this century, often quite hazardous attempt to reclaim and understand our past- the real one, not the invented one (Valaskakis 98). This reveals a continuing disagreement over the meaning of land in Native and North America. Land is linked to contingent identity and history absorbed in the discussion of territory and spirituality, worked in the power of privilege and politics. The meaning of land appears in the cultural practice and historical specificity of Native North American life worlds. It is endorsed and worked upon every time Native people fish or hunt, visit the graves of ancestors, plant gardens, offer tobacco to spirit rocks or recognize the interrelatedness of these understandings of everyday life. However, the meaning of land is also articulated in the stories people tell about ceremony and heritage, places and people, loss, conflict and travel. The ownership of land and the meaning of land was not only expunged and devalued in the policies that came forward to eradicate or acculturate Indians. Native practices and expressions entail not only space but also time, both of which are essential to the political and spiritual construction of Native culture. The Native perceptive of space emerges as a governing construct that not only establishes time but also builds Native ideology, community and spirituality in relation to land. Both tribal cultures and the Native perceptive of shared relations are situated in space rather than time. Indian religion, ideology and history, come out in interaction with a given land and its life forms, in a lived reality of space that is hard to differentiate in the non-Native analysis. A Native communitys experience or observation of land, environment and place, gives rise to the Indian spiritual stories and myths that create the tribal sense of the past. Land, as noted by the author is the essential issue defining possible ideas of Native America, whether in the past, present or future. An intensely held sense of unity with given geographical en vironments has provided and continues to give the spiritual reinforcement allowing cultural unity across the entire variety of indigenous American societies. Critical Race Theory: Analyzing the critical race theory, we see that it draws upon paradigms of inter-sectionalism. Recognizing that racism and race work with and through ethnicity, sexuality, class and nation as systems of power, contemporary critical race theory often depends upon or looks into these intersections. The opening essay in the Dark Side, of the Nation: Essays on Multiculturalism, Nationalism and Gender The Paradox of Diversity, portrays a critical race theory. Bannerji argues that the label women of color a slogan herself uses is caught up in many of the dynamics that anti-racist feminists are fighting. Reviewing both British and US literature on multiculturalism and race, the author explains how the official policy of multiculturalism of Canada despite its significance, actually worsens the absurdity of this originally American expression. Bannerji argues that the term women of color is a pleasant and vague label that extended throughout option politics in the 1980s and 1990s. It signaled to race as color, created a name for building alliance among all women, and gave a feeling of vividness, brilliance or brightness of a celebration of a difference. However, this dialogue tightens political agency and becomes a piece of thought that removes class and the critical and hard edges of the notion of race. Using Louis Althussers concept of ideological state apparatuses, Bannerji examines how the discourse of diversity allows the Canadian state to cope with real economic, cultural and social tensions while retaining its vital capitalist, liberal individualism and camouflaging its historic colonialism and explicitly racist past. Taking her cue from Antonio Gramsci, the author argues that these dynamics of state supervision need to be evaluated in relation to civil society and everyday values, practices and ideas that include classifications of people. Thus, a phrase like women of color that may hold a remedy to liberal pluralism actually becomes a re-named edition of plurality, so vital to politics and concept of liberalism in which a color-coded self-discernment, an identity declared on the semi logical foundation of ones skin color, was rendered pleasant through this philosophy of diversity. While the central argument of the essay is that the discussion of multiculturalism, with women of color as an indicative example, obscures the daily and political actualities of women facing the racism of white privilege. Bannerji is not reproving or simplistically discarding it. Rather, she is evaluating under what circumstances this discourse has developed, and most notably, revealing how it might limit future struggles and possibilities. Bannerjis discussion of the label women of color demonstrates that the language, descriptions and categories we use are not just ideological expressions of power entrenched in economic disparities. Rather, they construct meanings themselves. They are a realistic activity and serve to either control power relations or offer new possibilities. Bannerji explains in the essay that to imagine a society entails making a project in which difference could be appreciated. She also assumes that the source of this divergence is just cultural difference. However, this hindrance is the outcome of a difference that has its roots in race. It is at this point that multicultural discourse is created. As mentioned by the author in the essay this multicultural discourse is founded on the difference, a difference that is created by contrast and comparison of the possible Canadian subjects: But color was translated into the language of visibility. The latest Canadian subject covering social and political fields was appellated visible minority, accentuates on both the aspects of being non-white and, therefore, visible in a manner whites are not and of being politically minor players (Bannerji 30). Although the vocabulary, of discrimination and exclusion has changed in the Canadian framework, the cause of the problem remains the same, and as a result, continues to have an effect on the everyday lives of immigrant communities in Canada. In addition, the terms of diversity and multiculturalism are exclusively agreed upon by the power that is dominant and, therefore, set up an uneven power imbalance. Based on Bannerjis essay, one could argue that the reputation of Canada as an ideal multicultural civilization is nothing more than a false impression of social and political acceptance and not in actuality a certainty on the ground. In addition, in this false impression of tolerance and acceptance of ethnic minorities, the cultures of immigrants who are white from the preferred class of immigrants, are much more renowned than that of nonwhite immigrants. As argued by the author and others like her, discussion of multiculturalism has resulted in definitional authority over nonwhite im migrants living in Canada with consideration to their socio-political and ideological location in society. Their distribution as visible minorities in Canadian society officially reduces them to a class that is deemed less powerful and, therefore, mediocre to the dominant White class. By bringing both, the critical race theory and indigenous thought together, I intend to outline the central doctrine of an emerging theory that I would call Tribal Critical Race Theory to tackle the issues of Indigenous People in the United States. I have put up this theoretical framework because it allows me to tackle the complicated relationship between the United States federal government and Native Indians. This theory emerges from both indigenous thought and Critical Race Theory and is entrenched in the manifold, historically and geographically located ontology and epistemologies found in aboriginal groups of people. Despite the fact that they diverge depending on space, place, time, individual and tribal nation, there emerge to be familiarities in those epistemologies and ontologisms. This supposition will be entrenched in these familiarities while at the same time recognizing the variation and range that exists between and within individuals and communities. While critical rac e theory serves as a framework in and of itself, it does not deal with the particular requirements of tribal people because it does not address Native Indians liminality as either political and racialized human beings or the experience of colonization. Teaching both methodologies will involve covering various issues such as the United States policies toward Indigenous peoples, which are rooted in imperialism. We will also look at White domination, and a passion for material gain. We will also look at how aboriginal peoples have a desire to attain and build tribal autonomy, tribal sovereignty, self-identification and self-determination. We shall also look at the concepts of knowledge, power and culture and how they take on a new meaning when scrutinized through an Indigenous lens. This theory will look at the educational and governmental policies toward Indigenous people and how these policies are intimately linked around the problematic objective of assimilation. While critical race theory argues that racial discrimination is widespread in society, combining both critical race theory and indigenous thought methodologies emphasizes that colonization is prevalent in society while also recognizing the role that racism played. Much of what Tribal critical theory offers as an investigative lens is a more culturally nuanced and a new way of probing the experiences and lives of tribal peoples since making contact with Europeans over 500 years ago. This is central to the distinctiveness of the place and space American Indians inhabit, both intellectually and physically, as well as to the distinctive, sovereign relationship between the federal government and American Indians. My hope is that Tribal Critical theory can be used to tackle the variation and range of experiences of people who are American Indians. In page 115 Valaskakis quotes Gerald Vizenor and writes, The literature of dominance, narratives of discoveries, translations, cultural studies, and prescribed names of time, place and person are treacherous in any discourse on tribal consciousness (Valaskakis 115). Thus the Tribal Critical Theory provides a theoretical lens for dealing with many of the issues facing Native Indian communities today, including issues of language loss and language shift, management of natural resources, the lack of students graduating from Universities and colleges, the over representation of Native Indians in special education and supremacy struggles between State, tribal and federal tribal governments. Ultimately, Tribal Critical theory holds a descriptive power; it is potentially an improved theoretical lens through which to illustrate the lived experiences of tribal people. Tribal Critical based on a sequence of ideas, traditions, epistemologies, and thoughts that are augmented in ethnic histories thousands of years old. While I draw on ontologisms, traditions, older stories, and epistemologies, the grouping itself is new. As such, I anticipate that this article will instigate a procedure of thinking about how Tribal Critical Race Theory may better serve researchers who are unsatisfied with the methods and theories currently offered from which to study Native Indians specifically in educational institutions, and the larger society more generally. By drawing my attention to the distinction between Native Indian place-based and Western time-oriented understandings of the world, I have to learn not only the rather obvious scrutiny that most Indigenous societies embrace a strong connection to their homelands, but also the position occupied by land as an ontological outline for understanding relationships. Seen in this light, it is a deep misunderstanding to think of place or land as simply some material item of deep importance to Indigenous cultures (although it is important); instead, it should be understood as a ground of relationships of things to each other.  Place is a way of experiencing, relating and knowing the world and these ways of knowing often direct forms of resistance to authority relations that threaten to destroy or erase our senses of place. This, I would argue, is exactly the understanding of place or land that not only fastens many Indigenous peoples critical assessment of colonial relations of command and f orce, but also our visualizations of what a truly post-colonial affiliation of nonviolent coexistence might look like. Summary: By studying Valaskakis essay Land in Native America, I have been able to examine the role that place plays in fundamental Indigenous activism from the perspective of the native Indian community. I have to understand that even though native Indians senses of place have been tattered by centuries of capitalist-colonial displacement, they still serve as a familiarizing framework that guides radical native Indian activism today and presents a way of thinking about relations between and within individuals and the natural world built on values of freedom and reciprocity. I have learnt that one of the most important differences that exist between Western and Indigenous metaphysics rotates around the central significance of land to Indigenous modes of thought, ethics and being. I have come to learn that when ideology is divided according to Western European and Native Indian traditions this essential difference is one of great philosophical significance. Native Indians hold their lands Place s as having the uppermost likely meaning, and all their declarations are made with this reference point in mind. While most Western societies, by distinction, tend to get the meaning from the world in developmental or historical terms, thereby placing time as the description of central significance. Valaskakis essay The Paradox of Diversity, has expanded my understanding on race and racism. Although it has become everyday to converse about the diversity of Canada and other western cultures that have resulted from recent patterns of international migration, this article has drawn my attention to the idea that observing only country of origin or ethnicity offers an incomplete and ultimately deceptive approach to understanding present-day diversity. Conclusion: In conclusion, through the article, I have learnt some of the ways in which the removal of power relations in the creation of multicultural communities from above is mostly felicitous for the states and ruling classes which express their socioeconomic and ideological interests. This article has enabled me to examine what the idea of diversity does politically. I have come to learn that it is an evocative term that indicates heterogeneity without authority relations by abstracting difference from social and history relations. The term contains an unbiased appearance that is attractive for practices of control as the classed, gendered and raced social relations of influence that generate the differences drop out of sight, thus facilitating the blaming of individuals for their own disadvantage. This article has made me understand how the created relations between heterogeneity and homogeneity, or diversity and sameness, rely on the underlying idea of an essentialised edition of a colonial European turned into a Canadian. This Canadian is the agent and subject of Canadian nationalism and has the right to make a decision on the degree to which multicultural others should be accommodated or tolerated.

Power of Men in William Shakespeares The Winters Tale Essay -- Europ

Power of Men in William Shakespeare's The Winter's Tale It has been said that in "The Winter's Tale" Shakespeare dramatises the contemporary struggle between masculine and feminine power. In light of this comment, examine the presentation of the relationships between men and women. Despite their many differences, contemporary society is now only beginning to realise their equal and respective roles in society. Since the beginning of time a contemporary struggle for equality has been present between masculine and feminine powers. The biblical stories of creation have often been used as an excuse to mistreat women. The mythical story of "The Garden of Eden" has been used to display women being easily seduced into wrong doing "The woman saw how beautiful the tree was and how good the fruit would be to eat... so then she took some of the fruit and ate it", how women corrupt men into wrong doing "Then she gave some (the fruit) to her husband, and he also ate it," illustrating women being dependant on men and men as dominant leaders going out to hunt for food "made him cultivate the soil from which he had been formed". Also because the male was created first "God took some soil from the ground and formed man out of it" he is often thought as being the perfection of c reation, where as the female is a helper "he formed woman out of the rob (Adam's.)" Â  Even after the Women's Social and Political Movement (WSPU), the work that the women assured responibility for during the World Wars and the feminist movement of the 1960's for women to be equal to men politically, economically and socially, inequality still exists today.

The Ultimate Diagnosis Of Diseases Health And Social Care Essay

Biomedical information sciences is an emerging field using information engineerings in medical attention. This interdisciplinary field bridges the clinical and genomic research by disputing computing machine solutions ( Mayer, 2012 ) . It is the scientific discipline of utilizing system analytic tools to develop algorithms for direction, procedure control, determination devising and scientific analysis of medical cognition ( Edward Shortliffe H, 2006 ) . It leads to the development of intelligent algorithms that can execute submitted undertakings and do determinations without human intercession. It focuses chiefly on algorithms needed for use and geting cognition from the information which distinguishes it from other medical subjects pulling research workers interested in cognition acquisition for adept systems in the biomedical field.Knowledge Discovery ProcedureThe term Knowledge Discovery in databases ( KDD ) has been adopted for a field of research covering with the automatic fin d of inexplicit information or cognition within databases ( Jiawei, et al. , 2008 ) . With the fast development and acceptance of informations aggregation methods including high throughput sequencing, electronic wellness records, and assorted imaging techniques, the wellness attention industry has accumulated a big sum of informations. KDD are progressively being applied in wellness attention for obtaining huge cognition by placing potentially valuable and apprehensible forms in the database. These forms can be utilized for farther research and rating of studies.Stairss in KDD ProcessThe chief challenge in KDD procedure is to detect, every bit much as possible utile forms from the database. Figure 1.2 shows the stairss in KDD procedure. Fig 1.2 KDD Procedure The overall procedure of happening and construing forms from informations involves the perennial application of the undermentioned stairss. 1. Datas choice 2. Data cleansing and preprocessing 3. Data decrease and projection 4. Datas excavation 5. Interpreting and measuring mined forms 6. Consolidating discovered cognitionData excavationData excavation, a cardinal undertaking in the KDD, plays a cardinal function in pull outing forms. Forms may be â€Å" similarities † or â€Å" regularities † in the information, â€Å" high-ranking information † or â€Å" cognition † implied by the informations ( Stutz J 1996 ) . The forms discovered depend upon the information excavation undertakings applied to the database. Figure 1.2 shows the stages in the information excavation procedure. Figure 1.3 Phases in the information excavation procedure The stages in the information excavation procedure to extort forms include Developing an apprehension of the application sphere Data geographic expedition Data readying Choosing the information excavation algorithms Modeling Mining forms Interpretation of forms Evaluation of consequences1.2.3 Development of informations excavationData excavation has evolved over three subjects viz. statistics, unreal intelligence ( AI ) and machine acquisition ( ML ) ( Becher. J. 2000 ) . Statistics forms the base for most engineerings, on which information excavation is built. The following subject, AI is the art of implementing human thought like treating to statistical jobs. The 3rd one ML can be exposed as the brotherhood of statistics and AI. Data excavation is basically the version of machine larning techniques to analyze informations and happen antecedently concealed tendencies or forms within. Figure 1.4 Development of informations excavation1.2.4 Machine acquisitionML is the construct which makes the computing machine plans learn and analyze the given informations they study, so that the plans themselves can be capable of doing different determinations based on the qualities of the studied informations. They have the capableness to automatically larn cognition from experience and other ways ( T, et al. , 2008 ) . They make usage of statistics for cardinal constructs adding more advanced AI heuristics and algorithms to accomplish its ends. ML has a broad assortment of applications in wellness attention. Clinical determination support systems are one among them.1.3 Clinical determination support systemsA clinical determination support system has been coined as an active cognition systems, which use two or more points of patient informations to bring forth case-specific advice [ ] . Clinical determination support systems ( CDSS ) assist doctors in the determination devising procedure. They give a 2nd sentiment in naming diseases therefore cut downing mistakes in diagnosing. They help the clinicians in early diagnosing, differential diagnosing and choosing proper intervention schemes without human intercession.Necessity of CDSSThe most important issue confronting a household doctor is the perfect diagnosing of the disease. As more intervention options are available it will go progressively of import to name them early. Although human determination devising is frequently optimum, the turning figure of patients together with clip restraints increases the emphasis and work burden for the doctors and decreases the quality attention offered by them to the patients. Having an adept nearby all clip to help in determination devising is non a executable solution. CDSS offers a executable solution by back uping doctors with a fast sentiment of what the diagnosing of the patient could be and ease to better nosologies in complex clinical state of affairss.Approachs for CDSSThere are two types of attacks for edifice CDSS, viz. those utilizing knowledge base and illation engine and those utilizing machine larning algorithms. ML systems are most preferable than regulation based systems. Table 1.1 shows the differences between regulation based and ML based systems. Difference between the two attacks for CDSS Rule based Systems ML based systems Synergistic hence slow Non synergistic hence fast Human resources are needed to do regulations at each measure in determination devising procedure Once the system is trained determination devising is done automatically without human intercession therefore salvaging adept human resources Knowledge base requires inference engine for geting cognition Non cognition base learn and update cognition through experienceML based CDSSML algorithms based systems are fast and effectual for a individual disease. Pattern acknowledgment is indispensable for the diagnosing of new diseases. ML plays a critical function in acknowledging forms in the information excavation procedure. It searches for the forms within the patient database. Searching and acknowledging forms in the biochemical province of morbid people is really relevant to understanding of how diseases manifest or drugs act. This information can be utilized for disease bar, disease direction, drug find therefore bettering wellness attention and wellness care.Requirements of a good CadmiumThe prognostic public presentation and generalisation power of CDSS plays a critical function in categorization of diseases. Typically high sensitiveness and specificity is required to govern out other diseases. This reduces subsequent diagnostic processs which causes extra attempts and costs for di fferential diagnosing of the disease. Additionally high prognostic truth, speedy processing, consequences reading and visual image of the consequences are besides compulsory for good showing systems.Common issues for CDSSIn CDSS systems determination devising can be seen as a procedure in which the algorithm at each measure selects a variable, learns and updates inference based on the variable and uses the new overall information to choose farther variables. Unfortunately finding which sequence carries the most diagnostic information is hard because the figure of possible sequences taking to rectify diagnosing is really big. Choosing good variables for categorization is a ambitious undertaking. Another practical job originating from the CDSS is handiness of necessary sample of patients with a confirmed diagnosing. If there were adequate sample from the population of given disease it would be possible to happen out assorted forms of the properties in the sample. The thesis addresses these two jobs individually.Organization of the thesisThe thesis is divided into 10 chapters Chapter 1: Introduction Chapter 2: Literature reappraisal Chapter 3: Motivation and aims of the work Chapter 4: Knowledge based analysis of supervised larning algorithms in disease sensing Chapter 5: SVM based CSSFFS Feature choice algorithm for observing chest malignant neoplastic disease Chapter 6: A Hybrid Feature Selection Method based on IGSBFS and NaA?ve Bayes for the Diagnosis of Erythemato – Squamous Diseases Chapter 8: A Combined CFS – SBS Approach for Choosing Predictive Genes to Detect Colon Cancer Chapter 9: A Hybrid SPR_Naive Bayes Algorithm to choose marker cistrons for observing malignant neoplastic disease Chapter 10: Hegs algorithm Chapter 11: LNS Semi Supervised Learning Algorithm for Detecting Breast Cancer Chapter 12: Decision and future sweetening.DrumheadChapter 2Literature reappraisalOverview of Machine larningMachine larning systems in wellness attentionAs medical information systems in modern infirmaries and medical establishments became larger and larger it causes greater troubles. The information base is more for disease sensing. Medical analysis utilizing machine larning techniques has been implemented for the last two decennaries. It has been proven that the benefits of presenting machine larning into medical analysis are to increase diagnostic truth, to cut down costs and to cut down human resources. The medical spheres in which ML has been used are diagnosing of acute appendicitis [ 27 ] , diagnosing of dermatological disease [ 28 ] , diagnosing of female urinary incontinency [ 29 ] , diagnosing of thyroid diseases [ 30 ] , happening cistrons in DNA [ 31 ] , outcome anticipation of patients with terrible caput hurt [ 32 ] , outcome patients of patients with terrible caput hu rt [ 33 ] , Xcyt, by Dr. Wolberg to accurately name chest multitudes based entirely on a Fine Needle Aspiration ( FNA ) [ 35 ] , anticipation of metabolic and respiratory acidosis in kids [ 34 ] , every bit good as associating clinical and neurophysiologic appraisal of spasticity [ 35 ] among many others. Mention [ 31 ] [ 103 ] .ML Systems procedureMachine acquisition typesApplications of MLML algorithmsCommon algorithmic issuesSolutions to the algorithmic issuesFeature choiceFeature choice has besides been used in the anticipation of molecular bioactivity in drug design [ 132 ] , and more late, in the analysis of the context of acknowledgment of functional site in DNA sequences [ 142, 72, 69 ] .Advantages of characteristic choiceImproved public presentation of categorization algorithms by taking irrelevant characteristics ( noise ) . Improved generalisation ability of the classifier by avoiding over-fitting ( larning a classifier that is excessively tailored to the preparation samples, but performs ill on other samples ) . By utilizing fewer characteristics, classifiers can be more efficient in clip and infinite. It allows us to better understand the sphere. It is cheaper to roll up and hive away informations based on a decreased characteristic set.Need for characteristic choiceFeature choice methodsPresently three major types of characteristic choice theoretical accounts have been intensively utilised for cistron choice and informations dimension decrease in microarray informations. They are filter theoretical accounts, wrapper theoretical accounts, and embedded theoretical accounts [ 4 ] . Examples of filters are 2-statistic [ 5 ] , t-statistic [ 6 ] , ReliefF [ 7 ] , Information Gain [ 8 ] etc. Classical negligee algorithms include forward choice and backward riddance [ 4 ] . The 3rd group of choice strategy known as embedded attacks uses the inductive algorithm itself as the characteristic picker every bit good as classifier. Feature choice is really a byproduct of the categorization procedure. Examples are categorization trees such as ID3 [ 15 ] and C4.5 [ 16 ] . John, Kohavi and Pfleger [ 7 ] addressed the job of irrelevant characteristics and the subset choice job. Pudil, and Kittler [ 20 ] presented drifting hunt methods in characteristic choice. Blum and Langley [ 1 ] focused on two cardinal issues: the job of choosing relevant characteristics and the job of choosing relevant illustrations. Kohavi and John [ 24 ] introduced negligees for characteristic subset choice. Yang and Pedersen [ 27 ] evaluated document frequence ( DF ) , information addition ( IG ) , common information ( MI ) , a 2-test ( CHI ) and term strength ( TS ) ; and found IG and CHI to be the most effectual. Dash and Liu [ 4 ] gave a study of characteristic choice methods for categorization. Liu and Motoda [ 12 ] wrote their book on characteristic choice which offers an overview of the methods developed since the 1970s and provides a general model in order to analyze these methods and categorise them. Kira and Rendell ( 1992 ) described a statistical characteristic choice algorithm called RELIEF that uses case based larning to delegate a relevancy weight to each characteristic. Koller and Sahami ( 1996 ) examined a method for characteristic subset choice based on Information Theory. Jain and Zongker ( 1997 ) considered assorted characteristic subset choice algorithms and found that the consecutive forward drifting choice algorithm, proposed by Pudil, NovoviE†¡covA?a and Kittler ( 1994 ) , dominated the other algorithms tested. Yang and Honavar ( 1998 ) used a familial algorithm for characteristic subset choice. Weston, et Al. ( 2001 ) introduced a method of characteristic choice for SVMs. Xing, Jordan and Karp ( 2001 ) successfully applied characteristic choice methods ( utilizing a loanblend of filter and wrapper attacks ) to a categorization job in molecular biological science affecting merely 72 informations points in a 7130 dimensional infinite. Miller ( 2002 ) explained subset choice in arrested development. Forman ( 2003 ) presented an em pirical comparing of 12 characteristic choice methods. Guyon and Elisseeff ( 2003 ) gave an debut to variable and feature choice.FS in clinical informationsRessom et.al [ 3 ] gives an overview of statistical and machine learning-based characteristic choice and pattern categorization algorithms and their application in molecular malignant neoplastic disease categorization or phenotype anticipation. Their work does non affect experimental consequences. C.Y.V Watanabe et.al [ 4 ] , have devised a method called SACMiner aimed at chest malignant neoplastic disease sensing utilizing statistical association regulations. The method employs statistical association regulations to construct a categorization theoretical account. Their work classifies medical images and is non applicable to textual medical informations. Siegfried Nijssen et al. , [ 10 ] have presented their work on multi-class co-related form excavation. Their work resulted in the design of a new attack for point set excavation on informations from the UCI depository. Their comparing included merely the new attack designed and the extension of the Apriori algorithm. Their consequences reveal comparison chiefly on the runtime of the excavation attacks. T. Cover and P. Hart [ 11 ] performed categorization undertaking utilizing K- Nearest Neighbor categorization method. Their work shows that K-NN can be really accurate in categorization undertakings under certain specific fortunes. Their consequences reveal that for any figure of classs, the chance of mistake of the Nearest Neighbor regulation is bounded above by twice the Bayes chance of mistake. Aruna et.al [ 6 ] presented a comparing of categorization algorithms on the Wisconsin Breast Cancer and Breast tissue dataset but has non provided characteristic choice as a pre-classification status. Furthermore they have analyzed the categorization consequences of merely five categorization algorithms viz. NaA?ve Bayes, Support Vector Machines ( SVM ) , Radial Bas is Neural Networks ( RB-NN ) , Decision trees J48 and simple CART. Luxmi et. al. , [ 12 ] have performed a comparative survey on the public presentation of binary classifiers. They have used the Wisconsin chest malignant neoplastic disease dataset with 10 properties and non the chest tissue dataset. Furthermore they have non brought out the consequence of characteristic choice in categorization. Their experimental survey was restricted to four categorization algorithms viz. ID3, C4.5, K-NN and SVM. Their consequences did non uncover complete truth for any of the categorization algorithms.FS in genomic informationsFeature choice techniques are critical to the analysis of high dimensional datasets [ 1 ] . This is particularly true in cistron choice of microarrays because such datasets frequently contain a limited figure of preparation samples but big sum of characteristics, under the premise that merely several of which are strongly associated with the categorization undertaking while others are excess and noisy [ 2 ] . Previous research has proven cistron choice to be an effectual step in cut downing dimension to better the computational efficiency, taking irrelevant and noisy cistrons to better categorization and prognostic truth, and heightening interpretability that can assist place and supervise the mark disease or map types [ 3 ] . Gene look analysis is an illustration of a large-scale experiment, where one measures the written text of the familial information contained within the DNA into other merchandises, for illustration, courier RNA ( messenger RNA ) . By analyzing different degrees of messenger RNA activities of a cell, scientists learn how the cell alterations to react both to environmental stimulations and its ain demands. However, cistron look involves supervising the look degrees of 1000s of cistrons at the same time under a peculiar status. Microarray engineering makes this possible. A microarray is a tool for analysing cistron look. It consists of a little membrane or glass slide incorporating samples of many cistrons arranged in a regular form. Microarray analysis allows scientists to observe 1000s of cistrons in a little sample at the same time and to analyse the look of those cistrons. There are two chief types of microarray systems [ 35 ] : the complementary DNA microarrays developed in the Bro wn and Botstein Laboratory at Stanford [ 32 ] and the high-density oligonucleotide french friess from the Affymetrix company [ 73 ] Gene look informations from DNAmicroarrays are characterized by manymeasured variables ( cistrons ) on merely a few observations ( experiments ) , although both the figure of experiments and cistrons per experiment are turning quickly [ 82 ] . in [ 12 ] , cistrons selected by t-statistic were fed to a Bayesian probabilistic model for sample categorization. Olshen et al [ 85 ] suggested uniting t-statistic, Wilcoxon rank sum trial or the X2-statistic with a substitution based theoretical account to carry on cistron choice. Park et al built a marking system in [ 87 ] to delegate each cistron a mark based on preparation samples. Jaeger et al [ 51 ] designed three pre-filtering methods to recover groups of similar cistrons. Two of them are based on bunch and one is on correlativity. Thomas et Al in [ 121 ] , they presented a statistical arrested development patterning attack to detect cistrons that are differentially expressed between two categories of samples. to detect differentially expressed cistrons, Pan [ 86 ] compared t-statistic, the arrested development patterning attack against a mixture theoretical account attack proposed by him. Besides statistical steps, other dimension decrease methods were besides adopted to choose cistrons from look informations. Nguyen et al [ 82 ] proposed an analysis process for cistron look informations categorization, affecting dimension decrease utilizing partial least squares ( PLS ) and categorization utilizing logistic favoritism ( LD ) and quadratic discriminant analysis ( QDA ) . Furey et al [ 39 ] farther tested the efficiency of SVM on several other cistron look informations sets and besides obtained good consequences. Both of them selected prejudiced cistrons via signal-to-noise step. two new Bayesian categorization algorithms were investigated in Li et al [ 68 ] which automatically incor porated a characteristic choice procedure. Weston et al [ 131 ] incorporate characteristic choice into the learning process of SVM. The characteristic choice techniques they used included Pearson correlativity coefficients, Fisher standard mark, Kolmogorov-Smirnov trial and generalisation choice bounds from statistical larning theory. Traveling a measure farther, Guyon et al [ 43 ] presented an algorithm called recursive characteristic riddance ( RFE ) , by which characteristics were in turn eliminated during the preparation of a sequence of SVM classifiers. Gene choice was performed in [ 50 ] by a consecutive hunt engine, measuring the goodness of each cistron subset by a wrapper method. Another illustration of utilizing the negligee method was [ 67 ] , where Li et al combined a familial algorithm ( GA ) and the k-NN method to place a subset of cistrons that could jointly know apart between different categories of samples. Culhane et al [ 31 ] applied Between-Group Analysis ( BGA ) to microarray informations. A few published surveies have shown promising consequences for outcome anticipation utilizing cistron look profiles for certain diseases [ 102, 14, 129, 140, 88, and 60 ] . Cox relative jeopardy arrested development [ 30, 74 ] is a common method to analyze patient results. It has been used by Rosenwald et Al to analyze endurance after chemotherapy for diffuse large-B-cell lymphoma ( DLBCL ) patients [ 102 ] , and by Beer et Al to foretell patient out of lung glandular cancer [ 14 ] .Semi supervised larningWithin the machine larning community, a figure of semi-supervised larning algorithms have been introduced taking to better the public presentation of classifiers by utilizing big sums of unlabelled samples together with the labelled 1s [ 12 ] . The end of semi-supervised acquisition is to utilize bing labeled informations in concurrence with unlabelled informations to bring forth more accurate classifiers than utilizing the labeled information entirely. A good overview of semi-supervised acquisition is provided by [ 7 ] .SSL methodsSemi-supervised larning algorithms can be productive, discriminatory or a combination of both. Some popular semi supervised methods within the productive categorization model include co-training [ 2, 5 ] . and outlook maximization ( EM ) mixture theoretical accounts [ 9, 1 ] . As a generic ensemble larning model [ 20 ] , hiking plants via consecutive building a additive combination of base scholars, which appears unusually successful for supervised acquisition [ 21 ] . Boosting has been extended to SSL with different schemes. Semi-supervised Margin Boost [ 22 ] and ASSEMBLE [ 23 ] were proposed by presenting the â€Å" pseudo category † or the â€Å" pseudo label † constructs to an unlabelled point so that unlabelled points can be treated every bit same as labelled illustrations in the boosting process. Regularization has been employed in semi supervised larning to work unlabelled informat ions [ 8 ] . A figure of regularisation methods have been proposed based on a bunch or smoothness premise, which exploits unlabelled informations to regulate the determination boundary and hence affects the choice of larning hypotheses [ 9 – 14 ] . Working on a bunch or smoothness premise, most of the regularisation methods are of course inductive. On the other manus, the manifold premise has besides been applied for regularisation where the geometric construction behind labelled and unlabelled informations is explored with a graph-based representation. In such a representation, illustrations are expressed as the vertices and the brace wise similarity between illustrations is described as a leaden border. Therefore, graph-based algorithms make good usage of the manifold construction to propagate the known label information over the graph for labeling all nodes [ 15 – 19 ]DrumheadChapter 3Motivation and aims of the workMotivation of the workFrom the literature study it can be seen that the machine-controlled systems for disease sensing, unluckily merely sort types of tumours or used for differential diagnosing of the disease. They do non choose the enlightening characteristic which contains necessary information for disease sensing. Raw information is used for preparation. Categorization utilizing natural informations without any pre processing techniques is a arduous work for the classifiers. The truth of the excavation algorithms is affected by the redundant, irrelevant and noisy properties in the information set. Generalizations of the machine acquisition algorithms are influenced by the dimension of the information set. Preprocessing techniques like characteristic choice and characteristic extraction eliminates excess, irrelevant properties and reduces noise from the information identifies prognostic characteristics therefore cut downing dimension of the informations. Many of the surveies available in the literature uses feature extraction techniques which transforms the properties or combines two or more characteristics therefore bring forthing new characteristic. Some surveies available in the literature utilizing feature choice techniques used either filters or negligees for choosing needed characteristic subset. Typically, filter based algorithms do non optimise the categorization truth of the classifier straight, but effort to choose characteristics with certain sort of rating standard. Filters have good computational complexness. The advantages are that the algorithms are frequently fast and the selected cistrons are better generalized to unobserved informations categorization. Different from filters, the wrapper attack evaluates the selected characteristic subset harmonizing to their power to better sample categorization truth [ 9 ] . The categorization therefore is â€Å" cloaked † in the variable choice procedure. Wrappers yield high truth. Furthermore, extra stairss are needed to pull out the selected characteristics from the embedded algorithms. To harvest the advantages of both methods hybrid algorithms are of recent research involvement. The thesis addresses the job of characteristic choice for machine larning through assorted methods to choose minimum characteristic subset from the job sphere. A good characteristic can lend a batch to the categorization. The classifier ‘s true value depends on the ability to pull out information utile for determination support. Existing CDSS systems are developed utilizing supervised algorithms, they require a batch of labelled samples for constructing the initial theoretical account. Obtaining labelled samples are hard clip devouring and dearly-won. But unlabelled samples are abundant. Semi supervised algorithms are suited for this state of affairs. These systems do non pull out the cognition available in the unlabelled samples. SSL combines both labeled and unlabelled illustrations to bring forth an appropriate map or classifier. When the labeled informations are limited, the usage of cognition from unlabelled informations helps to better the public presentation. SSL algorithms use the cognition from the abundant unlabeled samples for constructing the theoretical account.Aims of the workBetter the quality of medical determination support systems. Bettering the prognostic power of classifiers utilizing characteristic choice algorithms. Elimination of redundant, irrelevant and noisy characteristics without losing the important features of the information sphere. Improve generalisation of classifiers. Reducing the complexness of the algorithms.Benefits of the research workThe developed theoretical accounts in this research shall help the clinicians to better their anticipation theoretical accounts for single patients. More dependable diagnosing. Quality services at low-cost costs can be provided. Poor clinical determinations can be eliminated.

Technology and Genetic Engineering essays

Technology and Genetic Engineering essays For many years, man has been advancing his race through technology. Many things through those were questionable and questionable, but none are close to a certain technology today. And that would be genetic engineering. What exactly is genetic engineering? To put it shortly, it is where scientists splice, alter, and manipulate genes of one thing to how the scientist want it, and even insert that gene into a foreign host. This technological tool is too powerful for us to handle. It is advancing faster than we can expect. Because of this fact, genetic engineering raises many moral and ethical issues while also showing signs of many dangers. This controversially technology could be looked at two ways, one religiously and the other, scientifically and economically. First, let's talk a religious point of view on genetic engineering. With the current knowledge we have today in genetic engineering, life can easily be created and manipulated to one's liking. How can one "Play God" by creating and altering life at one's will and not at all feel guilty? Haven't we learned that trying to be on a level as God is a punishable act? Such examples are ones such as the destruction of Babylon. People at that time tried to build a tower high enough to reach God, but it was destroyed, a punishment by God that warned us of what will happen if we tried to get powerful as him. People say that God gave us the knowledge to discover. If this is so, did God give us the knowledge to make the atom bomb so we could wipe out cities and vast lives in an instant? Did God give us the knowledge to make deadly biological weapons to kill each other with? And did God give us the knowledge to be so advance in warfare today that the world could be destroyed in minutes? God did not give us the knowledge to do these things or for genetic engineering. Man ignorantly chooses his own way and chooses to venture out doing things that are wrong. So who are we to decide what sex a...
