DNA Fingerprinting and Profiling essays

DNA Fingerprinting and Profiling essays DNA Fingerprinting is also referred to as DNA profiling and DNA typing. It was first developed as an identification technique in England in 1985. The original use was to expose the presence of any genetic diseases. About three years later it became used to identify criminals through the analysis of genetic material and to settle paternity disputes. It is still used for those reasons today. The DNA fingerprinting process is called gel electrophoresis. It is a process that can sort pieces of DNA according to its size. The process is done by taking samples of DNA from the crime scene and comparing it with samples from the accused. Samples are taken from biological materials like blood, semen, hair, and saliva. In the testing process, the DNA samples are first entered into the wells in a gel-like substance called Agarose. The gel is placed between two electrodes, one negatively charged and the other positively charged. The wells in the Agarose are inserted on the negative side because DNA has a negative charge. Molecules of DNA then travel in lanes toward the positive side. Small molecules will travel farther than the bigger ones because they have an easier time moving through the gel. So the molecules will then be assorted according to their size. Next, the gel is X-rayed to see the parallel bands (showed by black bars on the film) in each lane. The separated molecules of DNA form a pattern of parallel bands that show the structure of the DNA. The pattern should never change for one person. In a court of law, the results of a DNA fingerprinting examination can be used to convict or acquit an accused person. If the accused's DNA matches the one at the crime scene then that person could be convicted. Critics believe that a DNA fingerprint may not yet be reliable enough to use in the court system. They question how accurate a DNA fingerprint is and the cost of it. They believe that it is not very accurate because only a segment o...

Qualitative Research- Fieldwork Observation Assignment

Qualitative Research- Fieldwork Observation - Assignment Example These issues can be accessed and evaluated through observation. This is true because most of the traits that determine students’ performance are physically portrayed. Most of these characteristics are associated with the environment which students grow in. For example, literatures have found that students brought up in poor backgrounds perform poorer than those brought up in middle class backgrounds (Billie & Bette & Wolfe, 2006). Specifically, physical characteristics like students behavior and the way they conduct themselves have a lot to say about their academic performance. In the effort to determine this concept, I sought to carryout a research through observation from a public school in a poor background setting. The aim of this research was to find out how the students conduct themselves and if their behavior conducts have any relationship with their academic performance. In learning theories, main focus is on behavioral psychology. For children to be able to learn and remember new things, some things are considered to take place in the learning process. According to Billie & Bette & Wolfe, (2006), some of these things are explained by behavioral and constructivism theories which focus their attentions on acquired factors that help the learner acquire knowledge. Burkhardt, (2004) asserted that students’ achievement is influenced by environmental factors such as cultural, ethnic, and socioeconomic factors. These factors are said to shape students behavior, which have adverse, effects on their academic performance. According to Burkhardt, (2004), students who come from poor back grounds have been found to perform poorly in their academic works. In some instances, living conditions are extremely harsh that the students have to attend school with empty stomachs. Field-notes My field-work started early in the morning at 7: am. I purposely decided to start my research at this hour in order to gather information on the arrival of students from the ir homes since this was a day school. Students started arriving some minutes after 7: am. There was only one teacher who had arrived by then. I later came to realize that he was the teacher on duty that day. He mobilized students in cleaning their classrooms and the compound. Most students were seen to be sluggish in responding to the teacher’s instruction. For example, when they were told to clean their classes, most of them hid themselves behind the classes. The teacher was forced to come after them with a cane. When the bell for the assembly was rung, some students were still arriving from their homes. In the effort to capture them for punishment, the teacher had difficult times as the students ran away while others hid themselves. In fact, some of those that were caught and given some punishment to do, they retorted to the teacher. When the lessons started, I visited one of the classes where I observed various occurrences. Some minutes before the teacher entered the class room, most of the students seemed not to be settled. They were discussing the previous night’s happenings. Some were chatting and gossiping. However, a few were seen to be preparing themselves for the lesson before the teacher entered. When the lesson started, some students were lying on their desks while others were busy chatting. In fact, remarkably few students concentrated on what the teacher was teaching. This was evident when the teacher asked questions related to what he taught. The students gave irrelevant answers while other said

Authenticity & Socio-econmic - Essay Example He believes that acquiring such material possessions should make individuals to be interested in the manner in which the users fulfill the necessity for service, inside the extensive culture of society. For instance, the leather couch, or the professional player ought to act as some means of bridging the divide between the indigenous and wider cultures. This is similar argument to Jhally views on consumerism, especially in his belief that advertising stresses a world in which desires in form of new materials, are reflected through the emphasizing of social relationships, rather than material possessions (Jhally, 3). This is because Jungen appropriation and remodeling of universal but industrially manufactured consumer goods, reveals how such goods tend to portray an influential identity of desirable global commodity. The most consistent stories told by the whole range of advertising, is consumerism. Whereby more economic growth implies added consumption, as well as more production. The entire range of advertisements insists on individual power, console, desires, appeals and pleasures. The values stressed by the ads include taking desires and then preconceiving them to tie with the universe of commodities (Phillips, 5). Jhally, Congdon and Blandy’s are right in implying that advertising drives individuals away from important human relationships with others within the society, as it reduces their capability to develop happiness. Jhally asserts that advertising takes away normality from the consumers. However, all of these critics of consumerism and advertising, places more emphasis on the issue between needs and wants. Undeniably, Jhally, just like Jungen tends to extend their criticism of advertising on commercialism, to be a disapproval of egalitarianism and marketing. Thus, such assertions that advertising colonizes or dominates contemporary culture are not entirely spot on,

Medieval Torture Devices Research Paper Example | Topics and Well Written Essays - 1250 words

Medieval Torture Devices - Research Paper Example The medieval age, also known as the Dark Age, was the lowest point of European advancement in terms of knowledge, academics, and technology (Wikianswers). It was in this stage in world history, tainted by dominance of the nobles and the medieval Christian churches, that unimaginable and inhuman torture devices were created and utilized by the ones in power. One such device that is very much known to everyone is Flagellation, more commonly referred to as Whipping. Flagellation was a common practice during the medieval times to administer justice in the form of torture to the convicts (D'Silva). It was fast, effective, and painful. It originated and used extensively during the Roman Empire Period, however, it still has gained considerable popularity to punishers during the medieval times (de la Sierra). Jesus Christ himself suffered from Flagellation before he was crucified on the cross. It was said that Christ was pinned to a column or any fixed object (Dewil), most probably for the p urpose of immobilizing him. The type of flagellant would sometimes differ on the crime committed or on the administering people (D'Silva). Often times, whipping does not lead to death. Should the authorities wish to punish the convict more because of added crimes, other forms of lethal punishments are utilized (de la Sierra). Another example would be the Iron Maiden, sometimes called the Virgin of Nuremberg. This type of torture mechanism is made up of a thick casket of iron shaped like sarcophagus with iron spikes protruding in the hallow insides of the device (Cork-Screw.com). Such device does not actually hit any vital organ; the spikes are strategically placed to prolong the pain and suffering. The casket of the Iron Maiden is so thick that neither a sound nor a single speck of light comes in and out of the device, even amidst the howling and shouting of the person inside the device. The casket stands to more or less 7 feet in height and could accommodate a full-grown man inside (de la Sierra). The person inside the Iron Maiden stays hanged right-side up due to the pierced irons on his body. Whenever the doors of the Iron Maiden are open and consequently closed, the iron spikes would pierce the same exact spot, covering the wound it inflicted and inflicting tremendous and unbearable pain, but not death (Cork-Screw.com). Eventually, the person suffering inside would not have much option but to die a painful and slow death. The iron maiden does not quickly kill the victim due to one reason: interrogation (Medieval Torture: Iron Maiden). The device was used to interrogate the victim for days and days until the victim either spills out the information demanded from him or her, or the victim dies. When the time to interrogate the victim comes, the doors will be opened, and subsequently closed afterwards. Once the doors are shut, the victim could hear nor see anything outside, causing sensory deprivation and psychological turmoil (Medieval Torture: Iron Maiden). Europe was not the only one with a period of stagnation, and definitely not the only one

The American Olympic Association Essay -- Sports, Training, Olympic Ga

The United States Olympic Committee (USOC), initially named the American Olympic Association, was formed in 1896. Members of the committee sought to provide assistance to United States Olympic athletes with training and other needs. As the USOC is not government funded the committee has relied heavily on corporate funding and private donations (â€Å"Team USA,† 2011). However, over the years while the continued appeal of the Olympic Games remained, the increased cost of housing, clothing, and caring for U.S. athletes along with other professional sports vying for corporate sponsorship, made obtaining funding difficult. Thus, the USOC was challenged with persuading corporate benefactors that investing in the Olympic Games was a lucrative and cost effective venture (O’Rourke, 2010). Therefore, the methods used by the USOC to persuade companies to invest as well as motivating factors underlying corporate sponsorship are explored. Case Analysis Persuasion Message The ability to communicate effectively is essential in business (O’Rourke, 2010). In order to provide information, convey a message, and explain an idea, communication tools must be applied daily (N, 2005). The most important communication tool is the persuasive (N, 2005). This is due to the fact that whatever is being conveyed at the workplace requires a degree of persuasion (N, 2005). Hence, persuasion is the ability to move an individual or group into action. Boyer and Stoddard (2011), describe persuasion as â€Å"the act of getting a sentient being other than yourself to adopt a particular belief or pursue a particular action (p. 1). Therefore, in order for persuasion to be effective a level of trust between the parties must exist (O’Rourke, 2010). Thus, the challen... ... their association with the Olympic movement and develop interventions including updated marketing and promotional strategies to correct the problem. Moreover, an exclusivity right for some corporate sponsors has caused corporations without this type of contract to feel second rate which creates the possibility for ambush marketing to surface (Palomba, 2010). Ambush marketing is a company’s attempt to associate itself directly or indirectly with an event, team, or celebrity without being granted proper permission or pay the necessary licensing fees. As a result, official sponsors may not receive the full benefit or commercial value of paying to be legitimate sponsors (Palomba, 2010). Therefore, the USOC needs to protect legitimate sponsors by enacting or enforcing protective legislation to curtail or eradicate ambush marketing tactics (Palomba, 2010).

Self-Awareness Through Dis-Closure, Feedback and Reflection.

Throughout this assignment I shall discuss how I have developed my self-awareness through dis-closure, feedback and reflection. â€Å"Being self-aware enables us to identify our strengths and also those areas that can be developed† (R Ashmore & D Banks 2000 p47), self-awareness is continually being developed through the reflection of our life experiences.Reflection of my life experiences has given me the opportunity to become more aware of my strengths and weaknesses through being honest and the use of disclosure firstly to myself and then to others. The Gibbs Reflective Cycle 1998 is a useful model for reflecting on a life experience to gain further self-awareness through evaluation and analysis to finally having an action plan identifying what would be done differently in the future. The more knowledge we have about ourselves, the easier it becomes to relate to others† (R Ashmore & D Banks 2000 p47), the self-concept (Murphy 1947, Argyle 1969, Burns 1980) enables us to learn more of our self through self-image, self-esteem and the self-ideal, by reflecting on each of these three parts in regard of myself I have determined that I see myself as being confident with a high self-esteem which I find makes me a friendly and approachable person however I have also realised that I have to listen more to receive feedback. When we try to see and feel the world from another person’s perspective, we are trying to be empathic. If we are successful, we will not just be able to understand the persons thoughts but also feel something of what they feel† (G Firth, R Berry, C Irvine 2010 p148) within my past career path of working with people with learning disabilities with an inability to communicate it has enabled me to develop my empathy and consideration for others, which is not to be confused with sympathy but is more of a connection towards somebody else’s feelings.By developing my connection to other people’s feelings who are unabl e to communicate verbally it has enabled me to develop non verbal cues as described in Egan’s model 1998, such as adopting an open posture with a relaxed and unhurried appearance and the importance of eye contact, however within my new career role now working with people of which most can communicate verbally I need to stay aware that the use of non-verbal cues and the tone of the voice used is still of upmost importance. Self-disclosure, a process by which we let ourselves be known to others† (R Ashmore & D Banks 2000 p48) the Johari window can be applied to increase self-awareness and focuses on the theory that being more self-aware is of great assistance in developing as an individual, within the framework of the Johari window the subject of self-disclosure is of great importance.The Johari window is composed of four parts, the open self, blind self, hidden self and the unknown self, through the use of disclosure, by sharing information from your hidden self to other s the open self increases in size and in return for disclosing information feedback is received from others, giving insight into your blind self therefore increasing your self-awareness. Appropriate disclosure avoids the two extremes and means that it is fitting, suitable, the right amount at the right time† (Egan 1990 p45), it is important to ensure the correct amount of disclosure is made so that the relationship is not put at risk. Through disclosing too little information it does not allow for the reduction of uncertainty and also doesn’t allow for the build up of trust in a relationship, yet on the other hand if too much is disclosed to soon it may cause a feeling of pressure to recipertate. Self-disclosure between the nurse and patient occurs as part of the developing therapeutic relationship, where both must determine jointly what, when, where and how if at all they will disclose themselves† (R Ashmore & D Banks 2000 p 49) I have come to realise that no two relationships are the same and progress at different time scales depending on the individual and can also be determined by several variables such as age, status, gender or personality. Ultimately the use of disclosure in a therapeutic relationship is to gain trust and encourage reciprocity. Students may consciously chose to give little personal information to patients whom they perceive as ‘risky’ and likely to abuse the self-disclosure† (R Ashmore & D Banks 2000 p55) within my current workplace it is policy not to disclose personal information to the people we provide care for which can hinder the progression of a therapeutic relationship, however as I am unable to disclose my hidden self in reflection this has made me more aware of that the use of non verbal communication and the tone of my voice towards the people I provide support for helps to build trust, although on the other hand on reflection of feedback I have received it is apparent that if I have not c ommunicated effectively due to personal issues it can affect the way others feel and reduce the trust within the relationship. â€Å"Conveniently others are constantly giving you the very feedback you need to increase self-awareness† (J A Devito 2004 p33) to receive and further develop from the feedback received we have to be active and effective listeners. Related article: Secondary Reflection ExampleListening is a skill that can be thought of as effortless and undemanding however many people fail to listen to each other actively and are often either non or partial listening, whilst doing this we may pick up on partial bits of feedback but are not receiving the entirety. On refection the skill of listening is something I need to further develop as I can often find myself not actively listening to a person I am communicating with which is hindering the development of my self-awareness. In conclusion the growth of self-awareness is continually progressing over time and is never complete â€Å"becoming self-aware is an on going process that is never complete.Therefore, self-evaluation needs to be undertaken at regular intervals† (R Ashmore & D Banks 2000 p 50), evaluation of ourselves through reflection and the feedback we receive from others is a task which should be completed frequently to enable us to recognise both our positive and negative areas and ultimately becoming more self-aware giving us the means to manage the demands of both work and personal lives.

Illegal Immigration Should Not Be Illegal - 1722 Words

Every year there are around the same amount of immigrants entering the United States from Mexico as there are tourists. However, there is a difference; immigrants tend to be illegal unlike tourists and their passports. Ever since the United States offered what was said to be a new life for immigrants, they have been showing up illegally. There has been the same amount of opportunities as there are obstacles to overcome. Immigration at the U.S. and Mexican border has been a hot topic for decades now. Illegal immigration has not completely shown positive or negative effects on the economy, but more of a combination of the two. Illegal immigrants come to the U.S. to seek for better jobs, they tend to accept any job they are offered. For†¦show more content†¦This also includes the fact that aliens work higher than the maximum hours. However, the employer and the illegal immigrant must agree on a contract so the employer does not have to pay for the income or pay taxes. In America, businesses get â€Å"cheap work† benefiting themselves economically speaking, and illegal immigrants need of money makes this happen. Working as a maid, mowing lawns, farming, washing dishes in a restaurant or a hotel are a few examples of what illegal immigrants work as. These jobs are paid below the minimum wage. People don’t worry about having to clean their house because if they are part of the upper class then they can easily hire an illegal immigrant that will do it for about anything in return. According to Victor Davis Hanson from the NationalReview, he said â€Å"[. . .] the member of the blue-state elite envisions himself not as an exploiter of cheap labor, but rather more as a benefactor of the greater social good.† This is basically saying that the â€Å"Blue-state elite member,† (the upper class person) is not admitting that he does not take advantage of illegal immigrants working for little money, instead he is gaining benefits because of it. Upper class men are able to save money on such maids and others. Not only is this good from an individuals economical view, but for everyone socially. This is a way
