How Dna Technology Are Used in Solving Crimes? Essay

â€Å"I am strongly optimistic that enhancing the generation and the use of DNA information and analyses will contribute greatly to the field of criminal investigation and in effect, downgrade with expediency the crime rate in the country,† Angara said. What are those for? DNA matching will become an ever more powerful weapon against crime. Law enforcement will increasingly be able to identify suspects from biological evidence at crime scenes, saving investigative time and protecting innocent people from suspicion. When DNA evidence is properly handled and stored, it is well accepted by courts, and used to convict the guilty and free the innocent. There were different ways in solving crimes and identifying the correct suspects. This includes estimating time of death, forensic entomology, DNA profiling, analyzing blood stains and doing some autopsy. (Nicholson, 2012) But, which of this ways is the most accurate and which can give an unbiased result? The past decade has seen great advances in a powerful criminal justice tool: deoxyribonucleic acid, or DNA. DNA can be used to clear suspects and absolve persons mistakenly accused or convicted of crimes. DNA can be used to recognize criminals with incredible accurateness when biological data exists. Therefore, DNA technology is increasingly vital to ensuring accuracy and fairness in the criminal justice system. DNA is generally used to solve crimes in one of two ways. In cases where a suspect is identified, a sample of that person’s DNA can be compared to evidence from the crime scene. The results of this comparison may help establish whether the suspect committed the crime. In cases where a suspect has not yet been identified, biological evidence from the crime scene can be analyzed and compared to offender profiles in DNA databases to help identify the perpetrator. Crime scene evidence can also be linked to other crime scenes through the use of DNA databases. (Osuna, 2011) A certain police process covers up to 14-15 days or too long in terms of solving violent crimes. Arizona Scientist early develop rapid DNA testing machine that could cut DNA sequences in two hours. And so, it is easy to see results. Other ways take a lot of time and potentially damage the specimen. DNA evidence is generally linked to DNA offender profiles through DNA databases. For example, assume that a man was convicted of sexual assault. At the time of his conviction, he was required to provide a sample of his DNA, and the resulting DNA profile was entered into a DNA database. Several years later, another sexual assault was committed. A Sexual Assault Nurse Examiner worked with the victim and was able to obtain biological evidence from the rape. This evidence was analyzed, the resulting profile was run against a DNA database, and a match was made to the man’s DNA profile. He was apprehended, tried, and sentenced for his second crime. In this hypothetical case, he was also prevented from committing other crimes during the period of his incarceration. The development of forensic DNA technology in other countries and its potential to improve the Philippine criminal justice system are briefly discussed. The utility of forensic DNA testing in criminal investigations was highlighted using an actual criminal case wherein DNA evidence played a clear role in the resolution of the case. It aims to eliminate the current backlog of unanalyzed DNA samples and biological evidence for the most serious violent offenses — rapes, murders, and kidnappings—and for convicted offender samples needing testing, protect the innocent, improve crime laboratories’ capacities to analyze DNA samples in a timely fashion, provide access to appropriate post conviction DNA testing of crime scene evidence not tested at the time of trial, ensure that DNA forensic technology is used to its full potential to solve missing persons cases and identify human remains and develop training and provide assistance about the collection and use of DNA evidence to a wide variety of criminal justice professionals. (Ridgeway, 2012) In all, the availability of forensic DNA technology in the Philippines necessitates the amendment of current rules of evidence to incorporate scientific advances which enables the judiciary to better appreciate the value of physical evidence in criminal court s.

Positive functions for society Essay

The family was once described as a social group that shared common residence, consisted of at least two adults of each sex that maintained a socially approved sexual relationship and had one or more children, their own or adopted. This is a nuclear family, described by George Murdoch to be a universal family type. Although it is correct to say that nuclear families reside universally, family types now vary from single-parent families to gay headed families. Despite the variety, they contribute to the society, in ways that can be positive and negative too. Many sociologists differ in their views as to whether the family is positive to the society or not- functionalists believe that the family has positive functions that contribute positively to the society but it has to be said that functionalists tend to ignore negative aspects of the family such as the ‘dark side’, which consists of all that makes the family a negative experience for its members. Nevertheless there are sociologists that focus on only the negative aspects, such as, radical psychiatrists, radical feminists and Marxists. The new right theory has faith that family is a positive function of the society, however new rights only refer to nuclear families, as they believe that any other family type is inferior. Functionalism is a consensus theory which looks at society positively. Functionalists often make an organic analogy, as a human body is maintained by the functions of each part of a body, keeping it alive and healthy, similarly, and society is kept going by its institutions- family being one of the institutions which function to sustain the well-being of society. It is recognised by functionalists that families change themselves over time for the sake of adapting to society, an exemplar would be leading functionalist Emile Durkheim who strongly believed that family was the most important institution of society. Durkheim believed that family positively functioned for both individuals and society. The family, he believed, is the institution that offers its members emotional support, stability and gives them their identity as primary socialisers, and to an extent, teaches them how they should act toward the rest of society. Thus he proves that they perform a positive function to society too, as they provide fundamental social order and stability, which helps to prevent the society from becoming disordered. Talcott Parson’s was a functionalist who analysed the families  from a modern perspective and came to a conclusion that although families have less functions, as they are provided with help from outside agencies, they still perform two important functions which determine the actions within a society. These two functions focus on individuals- the first being the socialisation of children primarily, into the responsible, committed individuals that society can benefit from and the second is the stabilisation of adult personalities, as he stated that it was family who help ease away tensions of the modern world, particularly for male workers. He also believed that these functions were best found in nuclear families, where the clear sexual division in labour enabled wives to partake an expressive role while men held an instrumental role. However, there are functionalists like Fletcher who believe that family has not decreased their functions, he explains how the family do not just perform the apparent obvious functions of primary socialisation, social control and reproduction but they also play a role in providing basic education and support through school life and they still have an economic function because they provide support to their non-working members, whether they are un-fit to work, ill or unemployed and ultimately, family supplies the whole economy with workers. The functionalism theory sheds light on the positive aspects of family life which all contribute to the society positively. Each functionalist has consistently mentioned a vital performance that families partake- the primary socialisation of children. During this stage a child learns about his/her culture and is most likely to be taught the norms and values of their society. Primary socialisation is a vital performance which is done by the family, as a child is expected to have acknowledgement of the norms and values in order to adjust with the society they live in. Although the functionalist theory does not look at the negative aspects of the family there are others that do. It can only be assumed that the functionalist view was patriarchal- the belief that men are dominate. This assumption is only representative of Parson as he introduced the warm bath theory, whereby he suggested that it was men that had a hard day at work and their wives (women) stayed at home and made them feel better when the husbands came home. Radical feminists are those who focus on this discrimination and have firm belief that the world is wrongly dominated by  men. They believe that patriarchal ideology gives women a perception that motherhood is their natural role whereas it actually keeps women subservient to men. They express how women have at least a dual role but most have a ‘triple burden’ which consists of the roles of a paid worker, a mother and a housewife. The Marxist theory characterises the society as being one that exploits and subordinates the working class. They argue that the family only benefits capitalists as they produce the working class, teach their children to accept capitalist values when primarily socialising them, which are to hard work, accepting and respecting authority, and it is the family that makes their members feel that capitalism is the norm. Radical psychiatrists on the other hand, argue that the family as a whole is a deception. Clinical evidence proves that families suffer exploitation, oppression and a negative experience. The modern family is so ‘independent’ that it leads to emotional stress between the members. They disagree with functionalists and say that families actually spend too much time trying to please others by doing what they are expected to do, which prevents them from having autonomy. Thus if someone did something wrong it would lead to shame, guilt and repression. This leads to the’ dark side’ to a family which includes abuse to children and domestic violence to both men and women. Child abuse consists of, physical abuse, emotional abuse, sexual abuse and neglect. A CPS report showed that five to six children died each day in 2001 due to child abuse or neglect. Approximately 84% of the children were abused by their parents and mothers alone were responsible for 47% of the neglect and 32% of the abuse. Domestic violence is also increasing the UK’s crime rate and accounts for a quarter of the murders in the UK. Domestic violence is all the violence that occurs between partners. Not only does it account for physical violence but sexual and emotional abuse too. Although it is considered a crime against women because they are twice as likely to be threatened and injured, men are also violated against- a study conducted at the Leicester Infirmary in 1992 concluded that equal numbers of men and women were being assaulted at home and that men received more serious injuries, losing consciousness more often than women. It may be so that the family as individuals may be affected more if they suffer these negative experiences however, it may also affect the society because one’s participation to society will become effortless regardless of the way they contribute, for examples if they are a student,  they will not work hard, if they are a worker, they will be less. Nevertheless there are 400 refuges around the UK and any help lines to support those that are suffering. There are different views of the family that that highlight how they function in society and towards individuals. Functionalism is the main theory that promotes the positive aspects of a family and reflects the positive contributions a family makes towards society by performing essential functions such as reproduction, primary socialisation and social control. There are also many theories that focus on the negative aspects of the family- the things that make family a bad function of society. However, it has to be said that all the theory’s are correct if read from the perspective that they are written in. Thus, although the family does have a ‘dark side’ and may not comply with all theorists, such as radical psychiatrists and radical feminists, they still manage to uphold the main functions, that is to reproduce, socialise with individuals and support their family members.

What if Toward Excellence in Reasoning by Hintikka & Bachman Thesis Proposal

What if Toward Excellence in Reasoning by Hintikka & Bachman - Thesis Proposal Example The statements have been distinguished under the following headings:  Ã¢â‚¬Å"And you don’t have to be a sociologist to recognize that the prime motivation for virtually everything Americans do is entertainment; remove the entertainment motive, and you make the prospect of learning to read resemble an exercise in stoicism.†Ã‚  The premise is the part of a statement that serves as a support to the conclusive part of the whole statement; on the other hand, the conclusion is the part that expresses the final theme of the statement with the help of premise. The argument analyses of the given passage are as under Statement: â€Å"If you want an explanation for declining literacy rates in the U.S.†Ã‚  Explanations: These lines explain that it is not only entertainment, which is sought out by the masses. Rather, books provide the readers with knowledge, wisdom, and information too. Thus, television may be a source of amusement, but it is not true that books have been re placed by television because of seeking entertainment only.  Statement: â€Å"look no further than the boob tube.† (Intermediate Conclusion)  Explanations: This part of the statement speaks out television as the root-cause of falling literacy rate. The writers have used the slang phrase i.e. boob tube to mention television. As this part is based on conclusive assumption and does not emphatically prove the truth and validity of the real picture, it is, therefore, it can be stated as the intermediate conclusion.  Statement: â€Å"Spend all the money you choose on studies in an attempt to address the problem, but if you want my advice, you’d be better off unplugging the TV set.† (Final Conclusion)  Explanations: These lines disclose the conclusion of the argument, where the writers have refuted the idea that television has led to low literacy rate. Moreover, they do not agree to the notion that unplugging TV might increase trend towards reading.

Army Leadership - the Role of the Non-Commissioned Officer Essay

Army Leadership - the Role of the Non-Commissioned Officer - Essay Example These roles are to be performed by individual NCO corps as well as the NCO leaders. NCO vision The NCO vision requires that an NCO corps should be grounded in tradition, heritage and values that embody the perpetual learning of values and Warrior Ethos. In terms of roles, the vision requires that NCOs should be capable of training, leading and motivating soldiers. In terms of leadership, their chief role within the military organization is being a direct leader to the military officers. After the training of new recruits, NCOs are assigned to be the key direct leader and a trainer for crew, team and individual at the unit level (Chiefs of Staff, US Army, 1997). According to Fitton (1990), the NCOs are required to lead by example. This means they are expected to understand and practice the ethical requirements of soldiers and perform their duties diligently so as to give a practical lead to the other soldiers. Their role modeling is important for the military personnel because they ar e the most visible leaders within the military organization. The NCOs are required to provide inspiration, motivation and purpose for the other military officers because soldiers look to their NCOs for inspiration, solutions and directions/guidance. Due to their training, long-term service or experience in the military, an NCO officer should be capable of training other officers based on experience. They are supposed to help the soldiers to answer or overcome the challenges experienced in the contemporary operating environment by training them to prepare, cope and perform well no matter the prevailing situation. This means that they should be able to give high quality training to the soldiers. This training they give to the soldiers is also suppose to prepare them for their mission ahead and so they always stress on physical hardening and the basics of field craft. They do this because the need for physically and mentally fit soldiers will not be reduced by the tools provided by tec hnology (Bainbridge, 1976). The NCOs are senior to the soldiers they live, train and work with on daily basis and it is therefore their role to take care of the other soldiers. They are required to balance the mission for the military organization and the welfare of the soldiers. Each NCO should develop and demonstrate as a genuine concern about the well-being of the soldiers they are training or leading. Taking care of the soldiers also entails preparing them adequately to face any challenge that lies ahead of them. In order to achieve this, the NCOs ensure that they give the soldiers enough physical training and military practice for example clearing terrorists from urban strongholds or caves, or carrying heavy loads (Bainbridge, 1976). According to FM 7-22.7 (2002), it is the responsibility of the NCOs to set, maintain and enforce high-quality standards and discipline within the military organization because they are the standard bearers. They should ensure that all soldiers comp ly with the expected rules, discipline levels and military operation standard for example, military appearance. They are supposed to correct all military officers who do not wear their uniform properly while teaching them the right standards of military appearance. In connection to this, they are required to inspect for proper and serviceable equipment and clothing for their soldiers. The role to enforce military standard and discipline should be done

Final Exam - Essay Example Rondell Corporation traversed the path of success and growth in innovative engineering design of electrical items and radio broadcasting equipments. However, it failed to revamp its organizational structure and establish links between departments to restore mutual cooperation and consensus. This paper aims to look at the sources of conflicts at Rondell. With reference to Pondy’s model of organizational conflict, recommendations follow to improve the power relations, interdependencies and overall performance of the company. Prime culprit behind burgeoning conflicts at Rondell Corporation is ineffective organizational structure and power distribution. Though seemingly simple, poorly defined structure starts developing the following loopholes which ultimately leads to reduced agreement between departments and key personnel. Parent & Slack (1997, p. 221) opine that if an organizational is undergoing tumultuous phase due to differentiation and ambiguous roles, setting up of formalized rules, policies and norms of work practices and behavior can help solve the issues. High formality results in shaping up doubts, unclear job roles and even reciprocal interdependence. At Rondell, informal organizational structure rules the day-to-day operations. Departments have made subunits that in turn are running their individual politics and tactics to fulfill their personal interests. Lack of formalization has made departmental goals overshadow organizational objectives. Differentiation refers to dividing the tasks into smaller parts and allocating them to subunits of departments for better fulfillment of goals. Rondell has five major units or functions namely sales, engineering services, research and development (R&D), production and control. Though individual subunit orientation is necessary to contribute effectively to organization’s growth, these five departments at Rondell have deviated too far

Racial identity politics Essay Example | Topics and Well Written Essays - 2500 words

Racial identity politics - Essay Example THESIS STATEMENT: Despite the fact that Marable’s vision of resolving the issue of racial identity politics might seem rather radical and somewhat inconsistent with the ideas of other black leaders/scholars (for example, in his approach to the nationalist or integrationist movement), Marable provides a well thought out redirection of U.S. racial politics to a wider scope of activities and produces a new and meaningful understanding of race. Marable’s Interpretation of Race The perspective on dealing with racial issues within the contemporary American politics and economy, as expressed in Beyond Black and White: Transforming African-American Politics, is left, or, better, radically left. Specifically, in his interpretation of race, Marable relies on the primary role of class oppression. He observes the difficulty of disconnecting the national identity from the privilege which opposes the definition of race. This privilege, according to Marable, is determined by the super ior status of the white who comes from the upper class and is stereotypically a male. Yet, unlike the majority of thinkers, Marable does not contemplate the race in terms of White/Black opposition, but he sees race as the concept which lies at the intersections with many other types of subordination. Indeed, racism in the United States concerns not just African Americans, but also Asians, Native Americans, Latinos, Pacific Americans, as well as other people on the ground of ethnicity, color, mannerisms, or culture (Marable 5). Guided by historical materialism and Marxist approach in particular, Marable redefines the concept of race in the context of contemporary changes in economic and political life. According to Marable, rather than focusing on a narrow opposition between African Americans and whites, one should strive to develop a complex vision of the race’s instrumentality. This may well be explained by the changes in the fundamental structure of the United States econom y, for example, a flood of legal as well as illegal workers from the countries of the Third World, who basically redefined the meaning of race. This has led to considerable political consequences for all parts and classes within the American society. The innovative approach to interpretation of race found in Marable’s text takes the reader beyond the limited duality of the racial politics centered on black and white opposition. His vision of race is based on reconsidering the essence of â€Å"blackness† in African-Americans’ consciousness and political identity. Hence, the concept of race – of blackness – needs to be redefined both ideologically and with regard to material terms. This is necessitated by the fact that hundreds of thousands of people of Afro-American, Hispanic, and Caribbean origin move to the United States and get assimilated within numerous cities with other non-whites. Therefore, diversity and complexity are two crucial concepts t hat characterize black family relationship, religious affiliations, cultural traditions, and languages. This means that the

Discuss Quasi-Experimental Designs Coursework Example | Topics and Well Written Essays - 1250 words

Discuss Quasi-Experimental Designs - Coursework Example Multiple-baseline design differs from a reversal design in that the multiple-baseline design measures multiple variables prior to and after a treatment while a reversal design (also known as ABAB design) is a kind of single-case experimental design which can only measure a single case. Additionally, in Multiple-baseline design, treatment is often introduced to a multiple number of people at different intervals. Quasi-experiments have a number of advantages as well as potential weaknesses. Some of the major advantages of quasi-experiments include greater validity (as it involves more real world conditions) and significantly much more feasibility given logistical and time constraints (Trochim and Donnelly, 2008). On the other hand, the weaknesses of quasi experiments include less controlled variables, and lack of randomness. The absence of randomization is a fundamental weakness as it can lead to weaker evidence by making. This weakness does not always matter as long as it is recognized as quasi- experiment offers a powerful research tool especially in areas where true experiments may not be feasible. Yes, when participants are randomly assigned to groups, it is assumed that the groups are equivalent at the beginning of the study. This is particularly attributed to the randomness of the selection. However, the participants eventually became nonequivalent at the end due to the researcher’s lack of control over the selected participants for ach group. This may be solved by using pretests and covariance experimental designs. The particular outcomes of a given study can be used to effectively suggest that a threat is likely to have been present include covariation, temporal precedence as well as the presence of other plausible alternative explanation for the research results may reveal a threat to the validity of the research. a. Non-equivalent control group pretest only: Involves comparing the treatment and comparison
