Autopsy of a Crime Scene Essay Example for Free

Autopsy of a Crime Scene Essay 1.Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory (under resources at the bottom of the window), who is one individual that contributed to modern genetic analysis? What did this person contribute? I would say that analyzing the blood in a lab would be the best technique. Alec Jeffreys is known as the father of genetic profiling. He invented what is now an essential technique, especially in forensic science, called a polymerase chain reaction, or PCR. 2.How are computers used in fingerprint analysis? Experts examine tiny fingerprint details known as minutiae. These may be loops, dots, forks, islands, etc. Several comparison points must be perfectly matched for two fingerprints to be considered identical. 3.Who is a pioneer in fingerprint analysis? Describe a famous case that this person was involved in. Edward Foster studied fingerprint analysis in the US and introduced it to Canada. IN1911, Foster testified as a fingerprint expert in the Jennings case. Fingerprints in the wet paint next to Mr. Hiller, the murder victim, were the only clue. Foster demonstrated to the court that the prints of Thomas Jennings, who had been arrested as he was fleeing the scene, matched those left in the paint, and Jennings was convicted. 4.What is the role of the forensic chemist in crime scene investigation? These experts analyze all chemical, organic, and inorganic aspects of a sample. They separate the components and identify them using a variety of tests and devices. Their findings are used as evidence by the investigator and in court. 5.Who helped pioneer forensic chemistry? Describe one of her famous cases. France McGill became a pathologist and teacher is Saskatchewan. When Dr. McGill examined the stomachs of an elderly couple who had died on Christmas Day, she found a large quantity of strychnine, a powerful poison, along with the bran. The murder weapon was soon identified: the two of the victims had eaten bran muffins baked by their granddaughter. She had actually intended them for her father. She was charged with murder, but later acquitted. 6.In the ballistics laboratory, what is the water tank used for? Describe the analysis. To determine whether a bullet found at the crime scene actually came from the suspects weapon, it must be compared with  another bullet from the same gun. Ballistics experts fire it into a special water tank that slows and stops the bullet so that they can collect it intact. 7.Who helped pioneer ballistics analysis? What did he contribute? Wilfrid Derome was a multitalented Quebec doctor: a medico-legal expert, toxicologist, forensic photographer, medical examiner and scientific communicator. He founded the Laboratoire de recherchà © medico-legales de Montreal, the first laboratory in North America and only the third in the world. His motto: â€Å"Never allege anything you can’t prove.† 8.Why is measuring and diagramming the scene important? A police officer makes a sketch of the scene, measuring distances using measuring tapes and a laser meter. He notes the specific location of objects, Clues, and the body. The photos of this sketch will later be used to draw an accurate plan of the site on the computer. 9.What materials or tools would a crime scene technician use? A crime scene technician would use a camera to photograph the scene, a polilight to find clues that a rent visible to the naked eye, he would make diagrams and take measurements, they would use a magna brush and some type of colored powder to make any fingerprints more visible, and anything to properly take samples with. 10.From the activity and the information it had, what aspect of an investigation do you think you’d most like to work in? For example, would you prefer one of the laboratories? What appeals to you about this particular aspect of the investigation? I think I would like to work in a lab doing ballistics examination because I like to do a lot of puzzles and I believe that in some aspects it is like a big puzzle trying to figure out which gun fired the bullets at the scene.

Melting Pot of America :: essays research papers

Melting Pot of America Migrations As Population grew during the Paleolithic period, people wanted more space to live a roam about. Since they didn’t have a stable place to live, they were always moving and finding better places. Evidence indicates that the first peoples to migrate into America, coming from northeastern Siberia into Alaska (the Bering Straits), were carrying stone tools during Paleolithic period. They lived in groups of about 100. They used skin tents for shelter. They were nomadic, moving camp several times each year to take advantage of seasonal sources of food. Groups gathered a couple times a year to trade and gather valuable information that could be obtained about new sources of food or raw materials. It led families to move into new territory, eventually into Alaska and then farther south into the Americas. Evidence from the study of Native American languages, and materials, suggest that these earliest migrations may have taken place around 30,000 years ago. Bone tools, founded in Canada , have been discovered that have been radiocarbon-dated to 22,000 BC. Early Population It is estimated that at the time of first European contact, North and South America was inhabited by more than 90 million people: about 10 million in America north of present- day Mexico; 30 million in Mexico; 11 million in Central America; 445,000 in the Caribbean islands; 30 million in the South American Andean region; and 9 million in the remainder of South America. These population figures are a rough estimate (some authorities cite much lower figures); exact figures are impossible to ascertain. When colonists began keeping records, the Native American populations had been drastically reduced by war, famine, forced labor, and epidemics of diseases introduced through contact with Europeans. Europeans reactions Early Europeans were welcomed by the Native Americans to America. Native Americans viewed the visitors in amazement because of their clothing, ships, their technology (steel knives and swords, guns, mirrors, kettles) and other items unusual to the way of life of Native Americans. The ultimate goal for the Europeans was God, Gold, Glory, and it is because of this that ruined the good relationship between Europeans and the Natives. In the end the Europeans would overpower the Natives and would ultimately take their gold, have their glory, and make them believe in their god. Religion Most Native Americans believe that in the universe there exists an Almighty.

Hip-Hop Hold

John H. McWhorter's essay How Hip-Hop Hold Blacks Back discusses the popular subculture phenomenon of hip-hop and its effect on society. Recounting from experiences, McWhorther describes hip-hop as a counter-phenomenon which hinders the cultural and intellectual progress of the black community. Basing the development of hip-hop from the early 1960's to the 1970's, it emerged from the realism brought about by the oppression of the African-American community and how several ideologies, especially on activism, influenced the development of this genre.McWhorter argues on the effect of rap music as a means of creating a backward ideology; it does not provide any room for any intellectual development as far as culture is concerned. As such, he mentions in the end that rap music creates nothing. Rap revolution McWhorter states examples of historical implications of rap music. During the 1970's the idealism brought about by racial oppression, the black community raised different ideals towar ds apartheid and oppression, most notable of which were the ideals of African-American icons such as Malcolm X and Leroi Jones.The most famous of movements was the Black Panthers, a social group that inspired ideological activism as well as employing harsh measures in solidifying their claims. This gave rise to the ‘sticking it to the man' attitude, a kind of social behavior where authority does not apply and individuals tend to view themselves above such authority and law. From these ideologies, it also implies an individualistic notion towards the essence of rap music, which concentrates more on the life of a ‘gangsta' in the street, experiences on drugs, sex, and violence.According to McWhorter, rap music may be viewed as a cultural revolution of the society. That is, the message conveyed by these lyrics express a certain degree of the experiences of the past and conveying it as a detached attitude toward the status quo and authority. McWhorter used several words to d escribe rap music, and from such usage, his writing style clearly presents his bias against it, labeling the music as nonsense and profane. He also states rap music and ideology revolves mainly on the person's apathetic stance toward authority.As described by McWhorter, rap music retards black success since the music itself, according to him, only contains nonsense lyrics which celebrate street warfare, drugs, and promiscuity. McWhorter further mentions that ‘violence, misogyny, and lawlessness are nothing to sing about. He also explains the idea of ‘blaxploitation' which celebrates the idea of a black criminal as a revolutionary figure. This blaxploitation led to the development of the ‘gangsta' style, deviating from the early forms of rap as a ‘pop' or bubble gum music.Rap music is then associated with a constant mindset in disobedience and being above the system. From this point on, rap music has become another form of self-expression, concentrating more o n the aforementioned themes. The lyrics found in these rap songs have become edgy and tantamount to literal translation. As McWhorter mentions specific rap songs depicting these themes, he focuses more on the rapper's individual experiences, as described by the life in the ghetto marred with hardships and suffering.The songs then further downplays into more explicit themes such as detailed depictions of violence and problems against authority such as the inclusion of policemen and its association with violence. As such, these songs then represent explicit choice of word use in the lyrics which directly imply the use of guns and violence and their encounters with authority. McWhorter also adds that the ‘gangsta' type of rap are interspersed with mysoginistic views, viewing women as mere objects and prone to obsscene defamation as expressed in the lyrics.In this case, McWhorter states the use of these words adhere to sexual promiscuity and an apparent attack on the image of wome n. This presents another world-view, according to McWhorter, as he sums up the ‘gangsta' hip-hop genre with ‘Life ain't nothin' but bitches and money' (McWhorter, 4). He then points out that his kind of rap music can go old quickly and the rap music that can truly sell are those that are edgy, political, and representing another view with authority and society. Cultural influences From the aforementioned themes, rap music has then developed into an alternative culture, as it reinforces another kind of social behavior.The meaning implied by the lyrics used in rap songs produces another method of thinking, and from these implications, the behavior that the hip-hop world presents can be accepted as societal norms. The article presents a semi-critique of the notion on rap music and society. McWhorter associates the evolution of the music during the oppressive state of the black community during the sixties and seventies. He implies that rap music is a regressed state of musi c. He argues that although the can remain revolutionary in essence, the themes rap music tries to espouse is somehow degrading to the advancement of the black culture.He mentions the gesticulations, speech mannerisms as influenced by rap music can hinder young black men in searching for careers because of this unruly behavior they find in rap music. He also states that even as the media depict the successful African-American people in the industry, rap music, he argues, still depicts black people are uncivilized. The article is a semi-critique, that in a sense, it only presents the cultural implications of rap music and its adverse effect on society. However, it merely acts as a pure critique rather than a practical critique of rap ideologies.In a way, the article only acts as a reminder of this existing subculture and it does not give any practical situations in which the culture of rap can be addressed. However, the problem also lies on rap's history. Because of its uniqueness and the ‘stick it to the man' attitude, it has permeated through the societal mindset and has transformed into another phenomenological event of human concept. The ‘gangsta' mindset is now deeply ingrained through the consciousness of its audience and therefore can be hard for any critique to change. McWhorter's tone and word used clearly portrays his bias against the ‘nonsense' of hip-hop.This ‘nonsense' is viewed both in the linguistic and ideal sense. Rap music's choice of words is often explicit and profane, and it uses such words with constant repetition as though it is a part of the ‘gangsta' vocabulary. There is even an implication from the examples given by McWhorter that profane words in rap is in itself a standard and to be without such words, it cannot be considered hip-hop or rap. The lingual problem is also associated with gesticulations and speech mannerisms, according to McWhorter, that is considered ‘arrogant' and ‘irritating'.A ccording to the author, the theme that rap music revolves around is nonsense, since it only concentrates on the experience of the individual in his/her conditions supported by a formative mindset from the past. Sex, alcohol, violence and drugs are common themes in rap music, and these degrade the possibility of cultural advancement of a real society not hindered by any racial bias or oppression.

Reflection On Human Behavior Experiments - 965 Words

Reflection on Human behavior†¦..when humans let go of humanity First of all, what is humanity? When I recall my lectures correctly human behavior is effected by nature and nurture. The makeup of a human genetics and its environment. From what I have learned from my Sociology classes and so far from the Psychology classed is that the ratio is about 50-50 percent. Although I suspect that the neutering and its environment might tip the scale towards an environmental factor what determines our human behavior and our situational behavior. This therefor could be the base of stressors that trigger how humans behave and interact within a society. It is possible the need in human to, fit in, in any situation that grooms a person’s socialization.

Trait Theory - 4213 Words

Trait theory - Wikipedia, the free encyclopedia Page 1 of 8 Trait theory From Wikipedia, the free encyclopedia Trait theory in psychology, is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of traits, which can be defined as habitual patterns of behavior, thought, and emotion.[1] According to this perspective, traits are relatively stable over time, differ across individuals (e.g. some people are outgoing whereas others are shy), and influence behavior. Gordon Allport was an early pioneer in the study of traits, which he sometimes referred to as dispositions. In his approach, central traits are basic to an individual s personality, whereas secondary traits are more†¦show more content†¦The five factor model in particular has been criticized for losing the orthogonal structure between factors.[8][9] Hans Eysenck has argued that fewer factors are superior to a larger number of partly related ones.[10] Although these two approaches are comparable because of the use of factor analysis to construct hierarchical taxonomies, they di ffer in the organization and number of factors. Whatever the causes, however, psychoticism marks the two approaches apart, as the five factor model contains no such trait. Moreover, psychoticism, unlike any of the other factors in either approach, does not fit a normal distribution curve. Indeed, scores are rarely high, thus skewing a normal distribution.[11] However, when they are high, there is considerable overlap with psychiatric conditions such as antisocial and schizoid personality disorders. Similarly, high scorers on neuroticism are more susceptible to sleep and psychosomatic disorders.[12] Five factor approaches can also predict future mental disorders.[13][14] Lower-order factors There are two higher-order factors that both taxonomies clearly share: extraversion and neuroticism. Both approaches broadly accept that extraversion is associated with sociability and positive affect, whereas neuroticism is associated with emotional instability and negative affect.

IT Infrastructure Architecture

Question: Discuss how you can automate an existing company's method of payment in its IT infrastructure. Identify positive and negative aspects of the selected model in relation to the operational health of an organization. Answer: Enterprise Architecture Enterprise architectures possess a unique feature to assess the alignment of the organization with the operational and managerial levels of the company. It is basically a picture of the future state roadmap in the political, managerial, technological and operational domains. They form the blueprints of systematically defining the current and the desired state of the organization. This architecture forms the one stop solution to many of the IT problems. There are many frameworks and models that are practiced and implemented in the industry each having its own strengths and weaknesses. Some of the major enterprise architecture models are Zachman Framework, Open Group Architectural Framework, Garter Methodology, and Federal Enterprise Architecture (Winter, 2006). There can be use of an independent framework or architecture or blended methodology to adjust with the changes. TOGAF is one of the enterprise architecture that is popularly implemented in the organizations. It has major components as Business Architecture, Application Architecture, Technical Architecture and Data Architecture. All of these elements combine to paint a clear picture of the landscapes of architectures in a way of informed decision making. TOGAF can also be blended with Zachman to over the problems and issues in the field of IT such as complexity, cost, critical information, matching market trends etc. The model is highly beneficial for the development of broad range of IT architectures enabling design and evaluation for the reduction of cost based over the architecture framework. Architecture Development Method is for the process definition of the business needs of the company in a neutral format. This framework also embodies concept of enterprise continuum to reflect range of abstraction in the process of development. It is designed to be flexible so that it may be integrated with the number of other types and models of frameworks of enterprise architecture. The greatest advantage is its easy accessibility and free resource availability (Urbaczewski, 2006). If an organization requires a boundary less information flow then the best model can be TOGAF for implementation of the structures within the enterprises. There can be assurance of the design and implementation procurement specifications as the amount of risk is reduced exponentially. It de-mystifies the architecture developme nt process by adding value and enabling the users to build a genuine system based platform for addressing business needs. It is rich in the technical layers and provides a wealth of reference material in the open framework. There are however, some of the major disadvantages too can be overcome by blending this architecture model and framework with other models. There is a need to strengthen the top three layers of implementation in the TOGAF (Jonkers, 2006) model. Any artifacts used in the model cannot be reused as they are ready made. Also, there are no standard templates provided for the entire domain to implement it in the form of block diagram. Also, it is difficult to learn it in the first go without extensive training. The payment process of the company can be implemented in the IT infrastructure in the form of enterprise resource planning (ERP) system either in the cloud infrastructure or as an independent software solution. It is the cornerstone for back office process management. Automation in the operations of the organization is a much required revolution in the industry. The online payment option is very flexible and feasible which revitalizes the entire organizational process (Pollin, 1999). The electronic payment methods can be utilized in innovation for customers including credit and debit cards, value cards and e banking and innovations enabling online commerce such as smart cards, encrypted credit cards and e checks.
