Forensic Science 4.5 - Essay Example One of the most important pieces of evidence is blood but usually by the time the police and the forensic scientists reach the scene of crime the blood is usually dried up. In this article we will learn the four different methods used to collect dried blood samples from the crime scene. These dried blood stains are attained from objects or various surfaces that do not have the ability of mobility and cannot be collected easily. The four methods are cutting, swabbing, scraping and elution (that is dissolving). Cutting is clearly appropriate only to the items or objects that can simply be cut off. Inspectors should not just simply cut off pieces from objects that can be presented intact for example shirts or clothing items. Sometimes bloodstains might be found on objects that according to the inspectors are too large or too complicated to bring in complete for example bloodstains on sofas or on the seats of a vehicle. In such cases, cutting of a portion big enough to have unstained sections on the edges for later comparisons is a good idea because taking in the whole sofa or vehicle seat is not a wise or suitable act (Gaensslen, Harris & Lee, 2008). Swabbing comprises the transferring of the blood sample from the surface on which it was onto some kind of swab. While working with dried blood it is necessary to humidify or to dampen the swab so that the blood sample can be transferred. The solution that is used in the swab has to be sterile so that it avoids any chances of the contamination of the blood sample from bacteria. Gauze sponges are usually more recommendable as they are already sterile and are more functional as swabs. Swabbing is useless in taking out blood samples from walls or even from tables or chairs (Gaensslen, Harris & Lee, 2008). Scraping comprises of utilizing an instrument with a straight or sharply edged face to scrape off the dried blood samples from a surface and to place it onto a clean laboratory glass plate

No topic - Essay Example He based moral requirements on categorical imperative. Aristotle thought that the human life has a purpose and proper function to do, which provides happiness to the individual. This he termed as the purpose of human beings. It was achieved by using one’s reason and logic. Kant used the example of the honest shopkeeper. The honest shopkeeper was considered a moral person because he was honest out of inclination. The shopkeeper feels that being a moral and ethical person brings him better reputation more business and profits. John Stuart Mill argued that human beings are capable of experiencing ‘higher pleasures’ as well as ‘lower pleasures’. In order to differentiate he stated that the higher pleasures produce better quality and more quantity of pleasure or happiness. While on the other hand, the lower pleasures tend to be more of selfish in nature. According to Locke the life of an individual is governed by reason and ‘the reason’ happens to be the basic driving force behind the state of nature. Locke came out with the thought that reason teaches us not to harm another in his life, liberty, health or possession. He further added that an transgressions will invite punishments. Hobbes and Locke both happened to be renowned social contract theorists, but their views differ on several aspects. For example, while Locke believed that man is by nature a social animal, Hobbes thought it otherwise and suggested that ‘society could not exist except by the power of the state.’ In my opinion Kant’s Ethical Theory stands out as one of the best. While on the one hand this theory talks about the Good will on the one hand, rationality and morality are also described as integral components of the human behavior. Kant advances the argument that the outcome of our actions cannot be accurately predicted, but the intent

Explain the Development and Relevance of System Development Life Cycles(IT) - Essay Example ign, implementation, and maintenance.   The System Development Life Cycle (SDLC) is also known as Information Systems Development or Application Development. Software concept, as the first step, is to identify the need for a new system. It consists of investigative study on whether a business impediment or opportunity exists; carry out a feasibility study to distinguish the cost effectiveness of the solution proposed. The method may employ IT professionals alone or confer with end-users who have the idea to enhance their work. The concept must go along with the organizations strategic plan to ensure compatibility with the overall strategic objectives of the company and must meet management expectations before any budget is allocated for its development. After doing the analysis and requirements fully identified, The IT personnel will perform architectural design and write the applicable specifications for hardware, software, people and data resources. The design must be submitted to the end-users for review to ensure that the design meets their need. The design will act as a blueprint of the new system that would help to identify and rectify flaws before building the final system. Assessed and conforming to the specified requirements, the IT personnel can now start building the final system. If the management decision is to purchase commercial software rather than developing a new customized application, the system development life cycle in most parts remains the same. Evaluation of off-the-shelf software and the process in purchasing the software will replace coding and debugging. Minor coding and debugging maybe required for optional system interface. This will link the existing system to the new system to enable communication between them. Another point to consider in SDLC is the equal importance of the planning stage. A good and precise planning will reduce errors in design stage and save a lot resources. A business and a project plan are formed during the

Research report on student consumerism - Essay Example However, only three questionnaires were returned and, consequently, considered within the research analysis. Thus, the sample is represented by three female full-time students, who live in the university dorm, are of the same age, but study different majors. The questionnaire they filled in included questions that would provide an insight to why they prefer some types of food over other and how their preferences have changed since their coming to the university. Literature Review Basis for the present research was derived from the analysis of available literature and research on consumer behavior in terms of consumers’ habits, preferences, and approaches to eating and food shopping. The major literature that advised present research included researches that had been conducted primarily among university students in Canada (Eichler, 1988) that studied factors influencing person’s food choices, difference in approaches to student diet, etc. Thus, according to Silverman (19 97) there is a â€Å"Weight Gain Attributed to University Life† phenomenon known as the â€Å"freshman 15.† It is a popular belief that university students gain an average of fifteen pounds during their first year of university (Mason, 2002). Although it is partly a myth, studies show evidence that the majority of students entering university do in fact gain a significant amount of body mass during their first year of university attendance, which is associated with the accumulation of body fat (Blaxter, Hughes, Tight, 2006) A research by Hammersley (1993) looks at the factors influencing a person’s food choices, which are numerous and the relationships between those factors are seemingly complex (Wolcott, 1990). There is a high level of variance between the factors identified and described by researchers; the number and specificity of these factors vary, depending on the scope of the study. (Yates, 2004) Researchers of Healthy University of Toronto limited their study of food security on the St. George campus to five main factors: time, location, cost, variety, and nutrition (Wolcott, 1990). In another study, Holliday (2007) described factors as four stimulus properties of foods: Budget-friendly, Energizing, Sensory satisfaction, and Time; this is known as ‘BEST’ (Holliday, 2007). In contrast, a qualitative study conducted by Ribbens and Edwards (1998) to assess adolescents’ perceptions of factors influencing their food choices uncovered numerous situation-specific factors; media, peer influence, body image, mood, food cravings, and vegetarian beliefs are just some examples (Ribbens, Edwards, 1998) Method In this research Interview method has been used to collect data from our target respondents. We used direct interview method to get the answers. Major reason to use this method is the Open ended nature of Questions which have been asked to the Interviewees but at the same time it was not completely an un-structured typ e of interview because we have used the list of questions to get the desired results for our research topic so one can say that this was the semi-structure type of interview. There is certain benefit for using this approach like, In this way respondents can easily express their feelings more easily and Convenient and in result of this approach the non-biased information can be easily collect to some extent.

Mercutio vs Romeo Essay Example for Free

Mercutio vs Romeo Essay Love is a hard thing to define but lust is a burning desire for another person, and it usually doesn’t last a very long time. Love can transform over years and still remain consistent. Lust is superficial when only the appearance is considered but nothing else, which can be called ‘love at first sight’. Lust is only a short-term relationship, whereas love leads to a deeper understanding of the other person and one develops affection and caring for them. Mercutio’s idea of love doesn’t involve commitment, is more realistic than Romeo’s view and Mercutio doesn’t allow love to inflict any pain. Romeo’s idea of love includes commitment, and has a deeper, more passionate love and he allows himself to be vulnerable to his emotions and lets them take over. Mercutio and Romeo’s view on love are both similar in the sense that they involve desire for a girl and they are driven by their emotions. Both are fuelled by madness and this leads to them making rash decisions that result in a big loss and in Mercutio’s case, his life. Mercutio’s anger and feud with Tybalt leads him to go mad and be stabbed to death. Romeo’s anger gets the better of him which results in him stabbing Tybalt, after just having married Juliet. In the end, Romeo’s grief over Juliet’s ‘death’ overcomes his will to listen to reason and this poor decision ends up terminating his life too soon. Another similarity is that both characters are captivated by looks. They both speak of a woman’s outer appearance and have rarely talked about their personalities. When Romeo first sees Juliet, he marvels at her beauty without trying to figure out who see really was. O, she doth teach the torches to burn bright! It seems she hangs upon the cheek of night, Like a rich jewel in an Ethiop’s ear; Beauty too rich for use, for earth too dear† (1. 5. L. 44-47) In Act II, Scene 2, we see Mercutio trying to lure Romeo out by describing Rosaline’s appearance, â€Å"I conjure thee by Rosaline’s bright eyes, By her high forehead and her scarlet lip, By her fine foot, straight leg, and quivering thigh. †(2. 1. L. 17-19) In the start of the play, Romeo and Mercutio think that all ther e is to ‘love’ is having sex. Even the servants, Sampson and Gregory mentioned wanting to sexually harassing the maids of the Montagues. â€Å"That shows thee a weak slave; for the weakest goes to the wall. † â€Å"’Tis true; and therefore women, being the weaker vessels, are ever thrust to the wall: therefore I will push Montague’s men from the wall and thrust his maids to the wall. † (1. 1. L. 12-17) This proves that most men in this time thought of themselves as superiors compared to women. As the play progresses, Romeo’s view on love changes after he meets Juliet. After meeting Juliet, he falls in love with her as a whole instead of just her appearance. While there are minor similarities between Mercutio and Romeo’s view on love, the differences are pronounced and deserve thorough examination because the line between lust and love is very confusing and many people in society mix the two up. On one hand, Mercutio’s view can be described as ‘a chase for something sexual’. He never mentions settling down with a girl and having a committed relationship. Mercutio, unlike Romeo, does not believe in fate deciding his path, instead he lives in the moment. Mercutio doesn’t let love overthrow his conscience and guide his actions. Romeo says â€Å"Is love a tender thing? It is too rough, too rude, too boisterous, and it pricks like a thorn. † (1. 4. L. 25-26), to which Mercutio replies with â€Å"If love be rough with you, be rough with love; Prick love for pricking, and you beat love down. † (1. 4. L. 27-28) In those lines, he talks about how in order to defeat love and to not have it afflict with your actions is to have sex instead of loving someone and go through the pain of them not reciprocating your feelings. On the other hand, Romeo has a romanticized view which is shown by his strong reliance on fate, and the stars. In these lines, Romeo says â€Å"I am too enpierced with his shaft, To soar with his light feathers, and so bound, I cannot bound a pitch above dull woe. Under love’s heavy burden do I sink† (1. 4. L. 19-22) Romeo is being pulled down by the amount of pain from not being able to see Rosaline. At first he’s a victim of being caught up in Rosaline’s looks and mistook it as love. It wasn’t until he met Juliet that he truly discovered the true meaning. Romeo wallows in self-pity and loves by night. â€Å"I have night’s cloak to hide me from their sight; And but thou love me, let them find me here: My life were better ended by their hate, then death prorogued, wanting of thy love† (2. 2. L. 75-78) In contrast, Mercutio appears in the play mostly in the day and shows that he believes he can control his life and is more realistic than Romeo. He serves as the contrasting character to show a ifferent perspective on love from Romeo’s passionate, and emotional view on love. In culmination, Romeo’s idea of love is stimulated, loyal, and susceptible to pain. Romeo shows his vulnerability and readers and viewers of the movie have an easier time relating to his feeling for heartbreak. His loyal and never changing love for Juliet even as she was ‘dead’ made readers fall in love with his character. Although Romeo and Mercutio have different perspectives on love, they also have similarities which make them able to be such good friends.
