Workplace Security Essentials: A Guide for Helping Organizations Create Safe Work Environments Essay

MEMO Introduction                   This is to address the need of workplace surveillance for the benefit of both the employees and the employer. It is an important practice because it helps to prevent and reduces cases of theft, and also to monitor what the employees are engaging in during working hours. This is not any way targeting to infringe the employees’ rights of privacy. Video filming for surveillance will be done at sensitive departments only as allowed by the law and such areas include entrance and exits. Controversies                   The issue of workplace surveillance has raised controversies in the implementation because of the different interests of the employers and employees. Most of the employees are always not in agreement with the surveillance measures taken at their work place (Smith, 2010). These employees argue that surveillance has a negative effect on their productivity as it denies them freedom to work without fear of being watched. However, employers believe that surveillance is important as it keeps employees focused and more productive. It also reduces theft cases, which is beneficial to both the employer and the employees. Legislation                   Employees should enjoy some privacy rights at their workplace despite the presence surveillance by the employer (Stam, 2013). There are some places within the workplaces that employees cannot be monitored. Example of areas where surveillance cannot be done include the toilets and the changing rooms. If this legislation is not respected then the employees should sue the company for privacy rights infringement. Future Direction                   It is both important to have workplace surveillance and also give the employees their privacy rights as stipulated by the law. The company should in future harmonize the employees privacy needs with the need for surveillance in order to create a good working environment that serves both their interests. It is important for the company to monitor business communication to ensure that employees are doing the right thing (Staples, 2011). At the same time employees should enjoy their privacy at social places such as the tea room for their own talks out of the work area. Harmonizing the employer and employee needs, will create a better working environment. This increases the employers trust and makes the employees more productive due to job satisfaction References Smith, E. (2010).

Saving Normal

What is normal? Normal, like the word love, has no true definition and will differ with every person you ask. Defined in the dictionary normal is â€Å"to conform to a particular standard† or â€Å"desired pattern†. I believe most people will say a normal person is one whom is free from defect, handicap and mental illness. Metallization is a social process through which a previously normal human condition whether is be behavioral, physiological or emotional, becomes a medical problem in need of treatment.For example, not long ago being a shy person, â€Å"being reserved or having r showing nervousness or timidity in the company of other people†, was common and something most people experienced at some points in their lives. However, now shyness is out the realm of normal and made it's way into medical books. A shy person may now be one who is suffering from â€Å"avoiding personality disorder† or a number of other anxiety-relation mental disorders that has to be treated with antidepressants. In Saving Normal, Dry.Allen Frances argues that a high percentage of people diagnosed with mental illness are actually normal. This widespread metallization of normality is leading to over-treatment and over-medicating of mental health issues. The biggest health threat that we face may be our health-care system. The Diagnostic and Statistical Manual of Mental Disorders, ADSM, has become the â€Å"bible† for physicists. It was first published in 1953 and since then has been revised several times. The ADSM is the go to guide for doctors, government and health insurers and also used in the law.Being the chair of the ADSM-IV task force, Allen Frances had the inside scoop on how the psychiatric community classified and defined mental disorders and illnesses. He then goes to explain how the newest edition of the ADSM causes people to be diagnosed and prescribed drugs when they actually don't need them. The ADSM-V has expanded criteria for diagno sis of certain mental or psychological conditions and added new conditions that redefine more people as having mental illness. Both of these issues lead to ‘normal' people being labeled as patients in need of pharmaceutical treatment.It is worrying that the decisions about ADSM-V categories are made by experts with financial ties to the industry that benefits most from a widened patient population. Having criteria that is too broad means that people who would do well without medication are being restricted drugs they don't need and may possibly be harmed by. The problems with over-treatment and over-diagnoses as they relate to mental health are alarming. For example, the widespread diagnoses of mental health conditions such as bipolar disorder, autism spectrum disorder and attention deficit hyperactivity disorders, is appalling.ADD used to be only diagnosed to a small percentage of children, but currently all matters of activeness and disruption a child shows in their classroo m is being initialized. Some kids, particularly boys, are by nature more active than other. Childhood has now become an illness, what now passes for ADD is nothing more than normal variation or developmental difference. Two-thirds or more of active kids who have been mislabel ADD suffer unnecessary stigma, reduced expectations and harmful side effects from the drugs they're on.Metallization has increased the profitability of the pharmaceutical industry. Before you sell a drug you have to sell an illness. Therefore pharmaceutical companies now not only market drugs, but also they market illnesses as well. As relating to ADD, the misleading marketing by drugs companies to push their pills plays a big role in kids being assailable and mistreated once parents or educators view these advertisements. The rate of ADD in the United States has tripled to an inflated 11%. While the sales of ADD medications are approaching a profit of $10 billion a year.As Frances believes the biggest person w ho is responsible for diagnostic inflation is Big Pharmacy.. As soon as the drug companies were able to direct to consumer marketing, advertisements now convinced people that they had some type of mental illness. This resulted in them asking their doctors, mostly primary care physicians who have little raining in psychology, about a variety of prescription drugs. The doctors, whom are easily influenced by the young, sales representatives, are given free samples from drug companies which further pushes the prescribing of expensive medications.Primary care doctors prescribe 80% of psychotropic drugs and as mentioned prior have little training and/or little interest in psychiatry; in addition they spend little time actually evaluating symptoms. A majority of these doctors tend to favor pill solutions and some even build their practice on becoming known for passing out restrictions for whatever the patients wants. A consequence of diagnostic inflation leads to an increased cost for unne cessary drugs and psychiatric treatment.Americans are now spending billions of dollars on psychiatric medications but according to Frances â€Å"We are ignoring the people who have severe psychiatric illness; so that, one-third of people with severe depression see a mental health clinician, two- thirds don't. Two-thirds of people with severe depression get no treatment at all. At the same time, we're way over-diagnosing people who have milder problems that would get better on their own. Diagnosis can cause more harm than good when not really needed. We are over-treating those who don't need treatment, while neglecting those who do.The ADSM-5 medicals things that happen in everyday life, which makes the pool of normal a small puddle. In ADSM-5 normal grief become â€Å"Major Depressive Disorder†; forgetfulness due to old age is â€Å"Mild Unrecognized Disorder†; temper tantrums are â€Å"Disruptive Mood Desegregation Disorder†; gluttony is â€Å"Binge eatingâ⠂¬  and the symptoms for adult ADD most adults will qualify for. As many people are told they are sick, fewer people are being told they are well. This causes an epidemic of diagnoses and creates the impression we live in a sick society.Metallization may lead people to mistakenly believe that they should feel normal all the time despite the life stresses, worries or disappointments they may be going through. This may cause them to think that they have some type of mental illness that needs treatment when they are Just experiencing regular events or feelings that may people have. While these â€Å"normal† people are given ample treatment, this leaves those in actual the need of psychiatric help neglected. We have become a pill popping society. The misuse of legal drugs has now become a bigger public health problem than the use of street drugs.Emergency room visits for overdose on prescription drugs is more frequent than for street drugs. Prescription drug mortality rate is 16 ,000 deaths a year which is more than heroine and cocaine death combined. Frances states our country is spending far too much on unnecessary and often tyrannically harmful health care and far too little on education. Referring back to ADD in children, a large sum of money is wasted on the expensive ADD drugs that would be better invested in smaller classroom sizes and more facilities for physical activity that allow hyper-active children to blow off steam and wear their hypnoses out a little.There should be a better way of understanding and handling normal difference in one's activity, we shouldn't be spending so much money on medical treatment and exposing children to stimulants which have serious long-term side effects. Psychiatric treatment can be very efficient and effective when practiced correctly within appropriate boundaries. Failing diagnoses can result in a lawsuit, but however there are no consequences for over-treatment and over-diagnosis. Diagnostic inflation leads to i ndividual harm and high costs, both economically and socially.Because multiple powerful forces are promoting diagnostic inflation, it will most likely be hard to change it but education is key. People should be educated on disease mongering and be more skeptical and not eagerly believe what experts say. We can learn from Hippocrates rules of thirds: 1/3 gets better on their own, 1/3 don't respond to treatment and 1/3 really benefit from it. Medical experts should make it their goal to be able to tell them about and those who can benefit should be the only one's treated.

Fresias Deconstruction of American History Essay

Fresias Deconstruction of American History - Essay Example Fresia's thesis examines the criterion of democracy through the nodes of different 'centres', in his case historical personalities, who produce an ideological discourse. He discovers the manner in which it affects the society and how its "spontaneous" thought processes are absorbed in the cultural set-up of a nation. What is most important to notice in his assumptions is the manner in which he cites historical back-ups to his arguments. He starts off by claiming that the Framers of the American constitution were a conglomeration of people who wanted to create a situation of power for themselves. By citing various quotes, such as Benjamin Rush, who considered the plebs as "scums", Fresia makes it clear that the original motif of these people were to create a situation where by they could carry on the legacy of dominance and pass it off by qualifying it as democracy. In doing so, he points the bloody manner in which the so-called 'sacred' American constitution came to be chartered: "Perhaps even more shocking than the personal opinions of the Framers, is the process by which the Constitution was ratified secrecy, deceit and even violence played key roles in the Constitution's passage. These unsavoury tactics were used by the Framers and their allies because the majority of the people were against the ratification of the Constitution." Fresia connects the historical facts with the contemporary American policy of elite decision-making. He points out that whenever, the interests of elites and the public interest coincide, and even if it does not, the elites tend to call the rosters. Fresia blames the policy of "unchecked corporate power" for this and goes on to elucidate the hypocrisy of these corporate-government elites, who in the name of national interest, formulates laws violating accepted standards of decency. He also explains that these covert and anti-democratic measures are not new developments but have been the method of guaranteeing class rule "ever since the Framers decided that they needed the present political system to protect their power and privilege". Fresia's deconstruction of American history follows Bordieu's pattern of the 'habitus' and describes how the discourse of Americanisation has been aided by the structuring of thought-processes, social engineering and archetypal pattern of understanding in a particular way (like the Christian concept of good and evil). The Descartian sense of logic which are propagated by these power mongers make them institutionalised instruments of Repressive State Apparatus: agents of repression, like the Police, that teach by force and violence, in order to maintain the necessary consensus. Fresia says: "As citizens we are supposed to be like the nation's school children who are given no choice but to stand by their desks and mindlessly recite a pledge of allegiance to a flag, a pledge that was introduced into schools at the turn of the century to counter the influence of ideas that immigrant school children had received from their parents and from distant lands." He goes on to quote Benjamin Rush's famous lines: "I consider it possible to convert men into republican machines. This must be done, if we expect them to perform their parts properly, in the great machine of the government of the state.": and deduce that the motif of

Non-Western CUltures and Decentering - Essay Example This gave them advantage over non-westerners in terms of political, military, and economic power. Compared to the modernity of the west, non-western cultures were not able to match up when it comes to technology and communication. As a result, western influence has dominated other cultures. First, there was colonization; which means that western countries expand their territories by occupying indigenous lands. Because of this, westerners were able to further expand their power, profit, and most importantly, they were able to exert their influence over other non-western nations. As western nations progress, non-western cultures struggle to held on to their ways and tradition. In a way, the people become resistant to change and modification of their own culture. Their ways and values handed down from generation to generation were simply incompatible with what the westerners introduce. However, the struggle against western influence had become futile as it cannot be helped that non-western nations are dominated by the west’s influence. The decentering of culture happens when non-western cultures are unable to preserve their cultural identities as a result of foreign influence. Prior to the arrival of the Europeans, African culture was already established throughout the region. Rich traditions and cultural practices were already observed within the African community. While Africans live differently from Europeans, they were able establish a unique civilization in villages which are inhabited by families and village leaders. African culture is characterized by rich display of music, art, and dance. Sayre (2010) described African dance celebrations as the â€Å"stages of human development, the passing of the seasons or stages of the agricultural year†. This means that African nations were agriculturally developed and they do not need to expand their territories for food. Moreover, Hermitt

Pediatric Nurse Population for ADHD Education Essay

Pediatric Nurse Population for ADHD Education - Essay Example Medications used in children should be of even greater interest due to the inability to monitor the effects of adverse reactions by objective methods. Nurses play a key role in the management of children with ADHD. This disorder may persist even to adult stages. The diagnosis of ADHD requires careful history taking ,use of standardized rating scales ,and close attention to patients behavior and informants reports. Statistics show that in order to fit in the field of nursing and favorably attend the ADHD patients especially the 6-18 age group, a nurse should be compassionate, and committed to help people. Skills, knowledge and competence are a major factor of requirement in the nursing career. Different ADHD patients will react differently to the particular drug regime .This is due to their different individual genetic system which stimulates enzymatic reactions. Nurses ought to understand this aspect in order to attend the affected effectively. Primary care should be an opportune location for close monitoring of individual reactions to drugs. Systematic follow-up is essential to monitor side effects, target outcomes and gather information from parents, teachers and the child. Yearwood, E. (2012).

Form food safety enforcement Essay Example | Topics and Well Written Essays - 1500 words

Form food safety enforcement - Essay Example However, the basic purpose of this paper is to evaluate the successful outcome or otherwise in the cessation of the outbreak, identification of what went wrong and the measures needed to prevent a recurrence. Food poisoning is defined under the Food Safety Act as 'any disease of an infectious or toxic nature caused by or thought to be caused by the consumption of food or water' (HPA) 2004 (Management of outbreak of foodborne illness in England and Wales). Food safety laws in the United Kingdom center on protecting the consumer by ensuring that food is safe for consumption. Many provisions of the law focus on prevention rather than cure. Food business operators (FBOs) must show that they have adopted hygienic practices at their premises. The risks associated with food processing and preparation must be assessed by the FBOs, the food industry and the food laws enforcers. The degrees of protection are achieved through enforcement of specific provisions and through a framework that seeks to minimize the risk of unsafe food being present in the market. Any breach in the provisions of law results in criminal action. The law and its enforcement are governed by European and domestic laws. Actually, the provisions of law comprise broad principles and they are carried forward in more detailed forms by secondary legislation in domestic law. This process may change the fundamental principles upon which national legislation is based (Professor Bridget M. Hutter and Tola Amodu). There are many organizations in the United Kingdom involved in food regulations such as National Health Service, Local Health Boards, Chartered Institute of Environmental Health, and so on based locally, and at the national level. The ministers and central government officials formulate policy and tend not to be specialists in food safety protection. The Food Standards Agency (FSA) is an independent Government department with special knowledge in the domain. The FSA formulates policy whilst overseeing and directing the enforcement activity of local players. The Meat Hygiene Service is an executive agency of the FSA and responsible for statutory inspections of licensed premises including slaughterhouses, cutting plants and cold storages in the United Kingdom producing meat for human consumption (Background to the 2006 food hygiene legislation).

To What Extent Can We Attribute the Conditions of the Late Republic to Essay

To What Extent Can We Attribute the Conditions of the Late Republic to the Actions of Single Individuals - Essay Example Still, one of the most predominant means of scholarly analysis remains the conditions of the late Republic. Varying perspectives have considered the actions during this period in relation to a number of contextual criteria. The main modes of investigative inquiry situate the late Republic as either attributable to the actions of specific individuals, or the actions of these individuals merely attempts at restoring order. Analysis Sallust provides a broad ranging historical account of Rome. Rather than merely recounting historical events, Sallust works to diagnose the city in terms of psychic qualms. He first establishes Rome as a city of great courage and valor that later gives way to avarice and desire for power. He states, â€Å"At first these vices grew slowly, from time to time they were punished; finally, when the disease had spread like a deadly plague, the state was changed and a government second to none in equity and excellence became cruel and intolerable.†1 While Sa llust does not refer to a specific period of the Roman republic where such a situation emerged, there is the general qualitative recognition of Rome as not simply beholden to individuals, but rather, an entire state that had lost its way. To a large extent, the aforementioned psychic criticisms of the state are presented as a crumbling tapestry that gives way to conspiracies against the government. For instance, Sallust articulates Gnaeus Piso’s effort to overthrow the government. While, strictly speaking, this is the effort of an individual, within the epistemological context of the text, it appears to be the result of both general political strife, as well as the reduced values that overtook the late Republic. This, then, is the further recognition as the actions of the late Roman republic as occurring to restore order, rather than to respond to the ill-will of specific individuals. While Sallust articulates a late Roman republic that had experienced a widespread abandonmen t of proper values, he balances this depiction with criticism levied specifically at Lucius Sulla. Sallust states, â€Å"After Lucius Sulla, having gained control of the state by arms, brought everything to a bad end from a good beginning, all men began to rob and pillage. One coveted a house, another lands; the victors showed neither moderation nor restraint, but shamefully and cruelly wronged their fellow citizens.†2 Sallust extends these considerations of Lucius through recourse to specific historical events, as he indicates that Lucius permitted the army great liberties. The army, then, contributed to the sordid state of Roman society. This is the presentation of the late Roman republic as falling into squalor directly through the influence of an individual, Lucius Sulla. Another major area of consideration area issues related to Lucius Catiline. Sallust establishes a late Roman republic that, partly through the influence of Lucius Sulla, had collectively abandoned its va lues and given way to avarice. Sallust portrays Catiline as taking advantage of this social squalor. As Catiline emerges in Sallust text, there are conflicting accounts of his virtue and intentions. At one instant, Sallust portrays him as an opportunist, taking advantage of the youth and ill-social climate to achieve his aims. In another portrayal, Catiline is depicted as rebelling against a corrupt political order in a sort of Robin Hood-like way. In Catiline’

Making Invisible Work Visible by Andrew Parker, Rob Cross- Article Essay

Making Invisible Work Visible by Andrew Parker, Rob Cross- Article Analysis - Essay Example The researchers strive to present the recommendations for the firms through which they can attain better support work occurring in informal network of employees. The recommendations are based upon the research work conducted among a consortium Fortune 500 companies and government agencies. The researchers assessed collaboration and work in almost 40 information networks created within 23 different entities. The provided strategic and operational values are studies to find out their role in allowing the employees to collaborate and integrate their expertise with the organization. The article basically assesses and supports the information network and examines their significance for the organizations. The author believes that the informal social networks allow the employees to deeply understand and reflect the working patterns of the organization in much better way than the employees working in formal structure. The informal special networks however remain invisible and sometimes the m anagers fail to understand the problems developing within the firms. The authors also describe the background of the evaluation of the social networking techniques and inform that the idea sociogram is credited to Dr. J.T. Moreno who has been regarded as the inventor of social networks. He paved the way towards new approach of social structure and presents the concept of role and position. The article also stresses upon the importance of informal social network in the context of management challenges in globalization era. The informal networks are influenced from the information design of the organization whereas physical proximity and nature of the work also determine the structure of informal social networks maintained by the organization. The researchers also identified three specific areas where they believe that social network analysis is uniquely effective. These areas include "promoting effective collaboration within a strategically important group; supporting critical junctu res in networks that cross functional, hierarchical, or geographic boundaries; and ensuring integration within groups following strategic restructuring initiatives† (p28). The researchers found that social network analysis is a powerful and effective managerial tool that perform wide array of functions for the organizations. The patterns of information sharing within and across the networks also became visible through the social network analysis (SNA). Moreover, SNA allows identifying and solving the issues and problems being faced by the group of people within the organization. The specific behaviours of the employees could also be studies better and all this understanding allows taking the appropriate steps for improvement of group efficiency and effectiveness. There is wide variety of benefits of social network analysis identified by the researchers. They explain that information networks also support the employees' job satisfaction and performance that ultimately benefit t he overall productivity of the firms. It is very important for the management to understand the importance of social network because it the highly competitive market place they cannot rely upon the traditional networks and require the support of information social network to foster the process of communication with the employees and to avail wide range of benefits of informal social networks. The authors conclude that the present era is marked with

Starbucks Essay Example | Topics and Well Written Essays - 500 words - 7

Starbucks - Essay Example Productivity: â€Å"Starbucks plans to open significantly fewer new stores in the U.S., over the 2009 to 2011 period, to less than 400 net new stores per year, opening approximately 250 company-operated stores in each of the three years. At the same time, the company plans to continue to accelerate its International unit expansion, targeting net new store openings as follows; approximately 1,050 in 2009, 1,150 in 2010, and 1,300 in 2011† (Business Wire, 2008, 3). Competitive Position: â€Å"Total store count will be approximately 21,500 stores by the end of fiscal 2011, with the companys international presence growing from approximately 30 percent to over 40 percent of the global store portfolio† (Business Wire,2008, 3). Employee Development and Relations: Starbucks envisions to promote cultural diversity in the workforce and to continue providing comprehensive benefits and incentives, including access to numerous partner clubs and programs that assist in the holistic development of personnel, providing a balance between work and family life (Starbucks: Working at Starbucks, 2011, 1). Public Responsibility: Starbucks is committed to be a responsible company by extending corporate responsibility to the community, to protect the environment, to implement ethical sourcing of raw materials and provide wellness by awareness of health components in their products (Starbucks: Responsibility, 2011). This section requires an analysis of the firm’s current long-term objectives, as identified and enumerated under Section 1. In this regard, given the Starbucks had outlined their long term objectives in the light of the seven areas of profitability, productivity, competitive position, employee development, employee relations, technological leadership, and public responsibility, it is validated and supported that Starbucks possess the qualities that strategic

Stricter Penalties on First-Time Drunk Driving Offenders Essay Example for Free

Stricter Penalties on First-Time Drunk Driving Offenders Essay According to a study done by Mothers Against Drunk Driving, one in three Americans will be in an accident involving a drunk driver during their lifetime (Phong). Something needs to be done to address this matter considering the frequency of these accidents, the fatality of many of these accidents, and the accessibility of alcohol in today’s culture. An increase in penalties for first time offenders could significantly lower this statistic by encouraging drivers to not repeat their offense. Understandably, some people make mistakes and can correct them after their first offense. However, a larger number of people repeat this offense and are found driving under the influence or intoxicated after their first offense. Stricter penalties and punishments should be established for first time offenders because most drivers are inclined to repeat their offense, drunk drivers impact other people, and the current laws are ineffective. Stricter penalties need to be established to show drivers the importance of driving sober. First time offenders are incredibly likely to drive drunk again simply because they think they can get away with it. According to various studies, first-time drunk driving offenders are on the road anywhere from 88 to 500 times before they are caught in the act of driving drunk (Mejeur). To drunk drivers, it is worth driving drunk and running the risk of getting caught because they believe the chances of them getting arrested are close to none. This mindset needs to be changed completely. Intoxicated drivers need to understand that it is not worth the risk of driving under the influence. When deciding whether or not to hit the road under the influence, the punishments need to out weigh the benefits of driving intoxicated in the drivers’ mind. Mejeur reveals in another article that â€Å"5% of alcohol related fatal crashes involved drivers with more that 5 previous DWI (driving while intoxicated) arrests† (9). This means their first five arrests for driving under the influence did not deter them. Stricter penalties will encourage drivers to choose not to repeat their actions. Finally, â€Å"39% of the country’s drunk driving cases involved second time offenders, and 11% involved third and fourth time offenders† (Phong). Even after being convicted of a drunk driving charge, 50% of these drivers chose to drive on the roads drunk, endangering thousands of people. Clearly the legal system is not efficient in discouraging drunk driving after a driver’s first offense. This just shows that most first-time drunk driving offenders choose to drive under the influence of alcohol multiple times before getting caught, and even after, they choose to continue this incredibly dangerous behavior. Stricter penalties will deter drivers from getting behind the wheel under the influence. Since the actions of drunk drivers not only affect themselves, but they also affect others, there need to be more severe punishments for drunk drivers. In just 2004, 320 people were killed by drunk drivers every week, which is â€Å"roughly the equivalent of a weekly plane crash killing everyone on board. If that were the case, no one would fly and the public would demand change† (Savage). Many people are killed by drunk drivers, but the public has become so accustomed to hearing about drunk driving accidents, that no ones seeks to change this, because it has become the norm. The truth is that the number of people killed by drunk drivers has increased since then, yet there has been little change. When a drunk driver takes a person’s life, that person’s family must live with that decision the drunk driver made to get behind the wheel, for the rest of their life. When drivers drink and drive, they put thousands and thousands of people in danger. Their actions reach much father than they even realize. Of children ages 14 and under who died in a car accident last year, in 16% of these accidents had alcohol as a factor (Messenger 2). These are innocent children who find themselves either in the car with a drunk driver, or the victim of an accident with another drunk driver. If penalties were stronger for first time offenders, the number of innocent children whose lives are taken would drop. There are so many sad stories of people loosing loved ones to the poor choices of drunk drivers. In a story published by The Washington Post, Michael Pangle was arrested in 2002 for drunk driving and was released to the custody of a friend that same night. His friend drove him to his car where he went to another bar, got behind the wheel, and got into an accident killing himself and another driver; a father of three on his way home (Phong 3). Not only did Pangle lose his life, but he also took the life of a father of three; a husband to their mother. The family will have to live with this loss the rest of their life. The actions of drunk drivers can affect innocent people for the rest of their life. Laws need to be made to try and prevent this irresponsible behavior. The final reason to enforce stricter penalties is that the penalties in place now have little to no affect on the drivers and often fail to do any justice. Pam Louwagie found that ? of drivers pulled over by a police officer decline to take a breath test which results in a suspended license. Failing the test means losing your license, facing a drunk driving conviction, fines, and potentially jail time. Drivers’ auto insurance jumps, jobs can be in jeopardy because they now have a prior offense on their record (3). The choice is clear for a driver pulled over that has been accused of drunk driving. The penalties for refusing the test are a lot less severe than taking the test and failing. According to findings by Joe Mahr, â€Å"When drivers refuse to take a breathalyzer test, the law allows them to appeal the one-year suspension in civil court. But most prosecutors bargain away the suspensions as part of plea deals in criminal DWI cases. The end result: Defendants admit to drunk driving and don’t miss one day of driving† (2). It is evident that drunk drivers have found a way around the legal system. It should not be that easy for drunk drivers to get off a charge and be allowed to continue driving on the roads. Even after putting so many people in danger, including themselves. Stricter penalties are a necessity. Another weakness of the legal system is at the trial and sentencing phase. If offenders do not show up for a trial, a warrant is issued. However, people on warrants are rarely tracked down unless they are involved in another crime (Mahr 2). They can potentially avoid prosecution indefinitely. Many offenders know how to work the system to their advantage. The legal projection and punishments of drunk drivers needs to be reevaluated. Too many drunk drivers get out of being convicted of DWIs or DUIs and can continue to drive drunk, endangering many people. Since most drunk drivers are inclined to repeat their offense, the actions of drunk drivers affect on others, and current laws are ineffective, stricter punishments need to be established. The number of fatalities as a result of drunk driving is only going to increase if no action is taken, causing pain to thousands and thousands of people. This irresponsible act needs to be addressed because drunk drivers continue to get behind the wheel everyday with no regard for the law or those they put in danger. By demanding change and encouraging stricter punishments for first time drunk driving offenders, the number of fatalities will decrease and drunk driving will become less of a problem all across the nation.

Use Of Karyotype Analysis In Genetic Counseling Biology Essay

Use Of Karyotype Analysis In Genetic Counseling Biology Essay Complete set of metaphase chromosome is called karyotype. It is widely used to detect the chromosomal abnormalities that are related to the genetic diseases and various type of cancer. As the biomedical science advances, various kinds of techniques are used to analyze the human karyotype. These karyotype analysis are widely used in genetic counseling to minimize the risk of having unfortunate. By doing so, individual and families are realized to implement the genetic testing. In genetic counseling, knowledge of karyotype analysis is greatly determined the inheritable diseases including cancer. Moreover, Pedigree construction based on Mendelian principles is used in old days to know the pattern of inheritance. In recent year, FISH (fluorescence in situ hybridization), PCR (polymerase chain reaction), CGH (comparative genomic hybridization) and SNP (single nucleotide polymorphism) arrays are developed for the promising future of human genetics. Among them FISH is the most currently diagnostic tool for the various chromosomal aberrations that can be visible in karyotype analysis. The most tested chromosomes are 13, 18, 21, 22, X and Y that account for 85% of chromosomal abnormalities (Rodrigo et al., 2010). But now, genetic scientists have been carried out the approaches towards all chromosome analysis. On the other hand, the high risk society is greatly interested to do pre pregnancy counseling to reduce the inheriting defective gene for the next generation . Therefore, use of karyotype analysis is more and more improved in genetic counseling for the screening and diagnosis as well as the treatment and prevention. Karyotyping Karyotype construction and analysis is the powerful diagnostic method to identify the chromosomal studies in human genetic. Karyotyping is usually done at the metaphase of cell cycle in which the chromosome structure is the most condensed. Therefore, it is also known as complete set of metaphase chromosome (Nie et al., 1998). There are 46 chromosomes in human (22 autosomes and sex chromosomes). Karyotype show the number of chromosomes, the sex chromosome content, the presence or absence of individual chromosomes and the nature and extent of any structural abnormalities. Karyotyping can be accessed under a microscope to examine the number and structural variants which must be size of 3 Mb or more. Only DNA sequencing can be observed smaller alterations (Klein and Tibboel, 2010). Chromosomes in human karyotype are categorized into seven depend on their bands after staining procedure. Each group is arranged into A to G defined by size and centromere position. These banding patterns help to identify specific defect regions on the chromosome. Thus, the any defect in chromosome region can be described as an accurate address. For example; 1q2.4 defines as chromosome number 1, q arm, region 2 and the banding 4 (Trask, 2002). Method For karyotype construction, the specimen can be taken from the white blood cell, skin cells, amniotic fluid cells and the chorionic villus cells. Then the cells are prepared to enter the mitosis and arrested in the stage of metaphase. Moreover, these preparations are treated with trypsin and staining to get the banding pattern. After that, video camera attached microscope directly send the images to the computer to generate the karyotypes (Yang et al., 2000). Generally, it could be used to determine if chromosome of an adult have abnormality or defect that can be passed on to a child. The origin of complex chromosomal defect is identified by using standard G-band procedures, fluorescent staining and fluorescent in situ hybridization (FISH) and comparative genomic hybridization (CGH). FISH is a recent technology to detect the specific chromosome structure by using particular DNA probes. This method is more accurate and enables to see the micro-deletion and exact break point involved in each chromosome (Ligon et al., 2997). Doing the karyotype analysis is benefit in pregnant women at the age of 35 and having the history of previous child with defect. Because of the risk of chromosome abnormalities dramatically increased in advanced maternal age and if the mother is an X-linked carrier, the recurrent risk is 1 to 2%. Therefore, antenatal screening tests including karyotyping are carried out to a defined population who are at risk of having a specific condition. Different tests are done in different stages of pregnancy. Chorionic villus sampling is offered at 11-12 weeks of pregnancy, Amniocentesis is done at 16 weeks and fetal blood sampling is carried out at 18-22 weeks of pregnancy. Although these all procedures are having risk of miscarriage, they are suitable for the chromosomal and DNA analysis (Callen et al., 1988). Especially, for the detecting of trisomies in chromosome 13, 18, 21, X and Y which account for more than 85% of all fetal aneuploidies. As a benefit, if a couple with a known risk to offspring, they can choose options to avoid or plan further pregnancy. If the male partner is affected, the couple has option for artificial insemination of sperm from a donor. If the female is affected with a dominant condition or X-linked carrier, the couple has option for egg donation from another female. Moreover, the relatively new procedure is pre-implantation genetic diagnosis. Initially, this process requires in vitro fertilization. If the fertilization occurred, one cell is removed from the stage of blastocyst and then investigated for the chromosomal disorder. If there is no defect, it will be returned to the uterus (Fukuda et al., 2007). In the molecular genetics, DNA testing is divided into four main categories which are diagnostic testing, carrier detection, pre symptomatic testing for adult onset diseases and prenatal diagnosis. In the genetic counseling, karyotype analysis is widely used in carrier detection incase of balanced translocation carrier, autosomal dominant recessive, X-linked female carrier disorder in order to evaluate the risk of having an affected child. Furthermore, karyotyping can be used as a pre symptomatic or predictive test in some individual who are at risk of an adult onset disorder to determine whether or not they carry the mutated gene for these disorders. This test is value for autosomal dominant condition because of having a chance is 50% if one parent is affected. For example, familial adenomatous polyposis, colon cancer, Huntington disease (Bodmer et al., 1991). Chromosomal aberrations Abnormalities of the chromosomes, these are large enough to be visible under the light microscope are termed chromosomal aberrations. They are usually classified into numerical abnormalities and structural abnormalities. Numerical aberration is the disordered of chromosome due to error in separation of chromosome in cell division. Aneuploidy represents gain or loss of a specific whole chromosome due to failure of paired chromosome in meiosis. The one with extra copy of chromosome is called trisomy and the one with missing copy of that chromosome is called monosomy. These can be seen either autosome or sex chromosome. Autosomal trisomy will result in early miscarriage and monosomy of an autosomal chromosome is not compactable with life. Autosomal trisomy is associated with increased maternal age (Harper et al., 1995). Similarly, polyploidy represents a complete extra set of chromosomes due to fertilization by two sperms (dispermy) or failure in maturation divisions of either the eggs or the sperm. For examples, triploidy and tetraploidy depending on the number of extra sets of chromosomes. Triplody occurs in 2% of all conception but early spontaneous abortion is usual (Munne and Cohen, 1998). The most commonly seen autosomal aneuploidies are trisomy 21-Downs syndrome (47, XX, +21 or 47, XY, +21), trisomy 18-Edwards syndrome (47, XX, +18 or 47, XY, +18), trisomy 13-Pataus syndrome (47, XX, +13 OR 47, XY, +13). Sex chromosomal aneuploidies are Klinefelter syndrome (47, XXY), XYY syndrome (47, XYY), Triple X syndrome (47, XXX) and Turner syndrome (45, X). Autosomal monosomy is mostly lethal and autosomal trisomy is relatively more common (Rodrigo et al., 2010). The commonest autosomal trisomies are Downs syndrome, Patau syndrome and Edwards syndrome. The kayotype of Downs syndrome is 47, +21, an extra copy of chromosome 21. It occurs in 1 in 900 live births and leading cause of childhood mental retardation and heart defect (Wald et al., 1997). Patau syndrome is usually found at the time of doing cytogenetic analysis in malformed children. It also revealed extra chromosome at chromosome number 13 (47, +13) (Rasmussen et al., 2003). Another trisomy is the Edwards syndrome (47, +18). It accounts for a frequency of 1 in 11,000 live births (Massiah et al., 2008). Aneuploidy of the sex chromosome Aneuploidy of the sex chromosomes is more common than the autosomal aneupolidy but have less impact. Unlike the autosome, monosomy for Y chromosome is always lethal whereas monosomy for the X chromosome is a viable condition. The commonest syndromes that have ever seen in clinical setting are Turner syndrome, Klinefelter syndrome, Triple X syndrome and XYY syndrome (Smith et al., 1960). Monosomy of X chromosome results in 45, X karyotype due to non-disjunction in either parent. It is estimated that 1% of all conception from which 95 to 99% of all 45, X embryos die before birth. They have significant defect in height, sexual development and fertility but there is no mental retardation (David et al., 1986). The karyotype of Klinefelter syndrome is 47, XXY. The extra X chromosome of maternal origin is 56% and paternal is 44%. It is usually arise from non-disjunction at either the first or second meiotic division (Lamb et al., 1996). For example, if the father produces XY sperm that is cross over with maternal X ovum to produce XXY. This is the single commonest cause of hypogonadism and infertility in male. Overall the birth incidence of 47, XXY is 1 in 1000 male with an increased risk at maternal age and azoospermatic infertile males (Steinberger et al., 1965). And the karyotype of super female syndrome is 47, XXX which also known as triple X syndrome. It is usually appears as clinically normal but 15- 25% are mildly mentally handicapped. About three quarter of the affected females is fertile of which one- half of their offspring would expect to have this syndrome (Michalak et al., 1983). Furthermore, another karyotype defect associated with personality disorder is 47, XYY syndrome. It is firstly noted in 1965 cytogenetic survey in male for violent and dangerous antisocial behavior and about 4.5% of the males in this survey were shown as XYY karyotype. The frequency of having this characteristic karyotype in general population is 1 in 1000 birth according to the sub sequent studies. The recurrence risk for the offspring would be 2XXY : 2XY : 1XX : 1XYY due to production of YY sperm at the second meiotic division or post-fertilization non-disjunction of the Y (Staessen et al., 2003). Structural aberration is the disordered in the structure and shape of the chromosome resulting from chromosomal breakage and error in rejoin mechanisms. Translocation is the transfer of chromosomal material between non-homologous chromosomes but there is no DNA loss. Three recognizable translocations are reciprocal, centric fusion (Robertsonian) and insertion. The one important thing in translocation is the balanced reciprocal translocation which occurs in two non-homologus chromosomes (Michael and Malcolm, 1997). In normal population, 1 in 500 are known balanced carrier and they are clinically healthy but they can give a problem when they reproduce. It is possible for the balanced translocation carrier to pass on the translocation in unbalanced form that can lead to miscarriage and physical or developmental problem (Munne et al., 2000). Deletion is the loss of a part of chromosome that can cause phenotypic effect because of the loss of gene. For a deletion to be seen in karyotype analysis, the amount of deletion must be large. It may also occur as a result of an unbalanced translocation (Barber, 2005). Although deletion of a small piece of chromosome is not a serious problem, deletion of entire chromosome is lethal. Therefore, only a few viable conditions are found in large deletion. These are the listed below; Adapted from Human Heredity Principles and Issues, seventh edition, 2006 Region of deletion Related disease 5p- Cri du chat syndrome 11q- Wilms tumour 13q- Retionblastoma 15q- (maternal uniparental disomy) Prader- Wills syndrome 15q- (paternal uniparental disomy) Angelman syndrome Cri du chat syndrome is caused by deletion in short arm of chromosome 5 and incidence is 1 in 100,000 births (Cerruti, 2001). A characteristic feature of the affected child is having a sound of cat like cry (Niebuhr, 1978). The phenotype is slightly different depend on their chromosome break point. There are two regions of break point in the short arm of chromosome 5 have been identified in this syndrome. Loss of chromosome segment in 5p15.3 results in abnormal larynx development and deletion in 5p15.2 is associated with mental retardation (Overhauser et al., 1994; Simmons et al., 1995). Prader-Willi syndrome and Angleman syndrome are caused by deletion in region 15q11-13 or by uniparental disomy (Ledbetter, 1981). If both copies of chromosome are inherited from the father, the child will have Angelman and from the mother, the child will have Prader-Willi syndrome (Horsthemke, 1996). The incidence of Prader-Willi is 1 in 10, 000 whereas Angelman is 1 in 20, 000 live birth (Clayton-Smith, 1993; Petersen et al., 1995). Characteristic feature of Prader Willi syndrome is sleepiness and Angelman is bouts of laughter (Zori et al., 1992). These cytogenetic microdeletions in the long arm of chromosome 15 can be visible by using either FISH (fluoresce in situ hybridization) or DNA analysis with probes from the deleted region (Nicholls, 1994). The others structural abnormalities include duplication, inversion and mosiacism and the rare structural variants are fragile site, heteromorphisims, isochromosome and ring chromosome. Cancer genetics Some of the cancer can be detected by karyotype analysis. The connection between chromosome rearrangement and cancer is evident in leukemia. The specific chromosome translocation between chromosome 9 and 22 is called the Philadelphia chromosome. That can be used as well defined diagnostic tool and prognostic factor. Moreover, this specific translocation is associated with other forms of cancer including Burkitts lymphoma and multiple myeloma. Chromosome translocation associated with haematological cancers Translocation site Type of cancer t(9;22) Chronic myeloid leukemia (Rajasekariah et al., 1982) t(8;14), t(8;22), t(2;8) Burkitts lymphoma (Margrath, 1990) t(8;21) acute myeloblastic leukemia (Oshimura et al., 1976) t(4;18) follicular lymphoma (Fleischman and Prigogina, 1977) t(4;18) acute lymphocytic leukemia (Oshimura et al., 1977) The proportion of leukemia with a heritable component has been estimated as 25% in monozygotic twin. Risk to sibs in childhood leukemia is 2- 4 times higher than the population incidence. The risk of a relative developing Hodgkins disease is seven fold higher than other (Kelly, 1992). Genetic counseling Genetic counseling should be offered to both parents and must give adequate time under appropriate setting. Depth of explanation should be matched to education background of the couples, outlining of clinical features, complication, natural history, prognosis and effective management (Frets et al., 1991). Simple Explanation of the genetic basic of the condition with the aids of diagram and recurrent risk calculation should be carried out (Sermon, 2002). Furthermore, genetic counselor can give the suggestion to reduce the risk of having disorder. The options are no further pregnancy, adoption, in vitro fertilization with pre implantation diagnosis, artificial insemination-AID by donor (egg donation), termination pregnancy, OR ignore and accept the risk (Zare et al., 1973). AID is performed for husband with AD trait or both are carrier for a serious AR (Taranissi, 2005). The important thing in genetic counseling must be non- judgemental and non-directive. The aim is to deliver a balanced version of the facts which will permit the consultants to reach their own decision with regard to their reproductive future. In UK, congenital disabilities act of 1976 legal action can be brought against a person whose breach of duty to parents results in a child being born disabled, abnormal or unhealthy. Prenatal diagnosis with selective termination of pregnancy became a reality in UK with the abortion ACT OF 1967 (Macintyre, 1973). AD trait is the risk to each child of an affected person is 1 in 2. Disorder has high penetrance, most dominant trait shows variable expression. AR trait for the carrier parents, the risk recurrence risk is 1 in 4 diseases, 2 in 3 chance of being carrier (Yoshikawa and Mukai, 1970). In X-linked recessive trait, if females are obligate carrier, one half of her sons will be affected and one half of her daughter will be carrier. If affected male reproduce, there will be normal sons and carrier daughters. Nowadays, biochemical tests may be available for carrier detection, but because of X inactivation few of these are absolute and this information needs to be combined with the pedigree risk using Bayes theorem (Markova et al., 1984). Conditions need for genetic counseling and investigation (Watson et al., 1992) 1. Infertility one in ten of all couples are involuntarily infertile, such a couple need chromosomal analysis to exclude a balanced structural rearrangement and Klinefelter syndrome. 2. Recurrence miscarriage one of six pregnancy ends as a spontaneous miscarriage. 3-5% of cases have a balanced structural rearrangement 3. Still birth 4. Perinatal death with multiple malformations Conclusion The benefit of karyotype analysis in high risk population provides the prevention and early management options to minimize the risk. As the genetic science development, researchers and clinician have more advanced diagnostic tool like multiplex PCR, SNP microarray, CGH (comparative genomic hybridization) to identify the far more complex chromosome abnormalities. Although karyotyping by FISH can detect both balanced and unbalanced translocation, uniparental disomy can only be detected by SNP arrays and high output sequencing. Despite the high cost, enormous benefit can be found for the society to evaluate the superior treatment protocols and genomic technologies for the future.

The Future Of Education: On-Line Classes Essays -- School Internet Tec

The Future Of Education: On-Line Classes "The future is outside the traditional campus, outside the traditional classroom. Distance learning is coming on fast," says management philosopher Peter Drucker (qtd. in Ebeling and Gubernick). One form of distance learning, on-line education (courses offered over the Internet), has caught the eye of the public and is forcing educators to reevaluate the present state of the educational system. Because of their convenience, cost, and amount of and access to readily-available information, these on-line classes, specifically those in math and computer science, are becoming more and more prevalent throughout the Internet community. TARGET TECHNOLOGY Description On-line math and computer science classes are educational courses offered over the Internet. They differ from traditionally taught classes in that they offer a wealth of information which can be easily and quickly accessed with the right equipment (i.e. a computer and Internet connection) and knowledge. They also allow the user to log on to and participate in the class at any time of day at his/her convenience. This may prove advantageous to those with strict work schedules, to those with families, or to those who learn best at their own rate or at different times of day. "This format [on-line classes] is really good for older, nontraditional students who work full-time and have families," says Xeturah Woodley-Tillman, an on-line instructor at Metropolitan State College of Denver (qtd. in Brown). History The presence of and participation in on-line math and computer science classes has been rising ever since the Internet became readily available to the public. For example, four years ago Peterson's college guide li... ...lemented and fully utilized. While they alone may not change the current state of the educational system, on-line math and computer science classes should be a welcomed addition and should continue to grow in use far into the future.

Struggle Between Good and Evil in William Goldings Lord of the Flies E

The Struggle Between Good and Evil in William Golding's Lord of the Flies   Ã‚  Ã‚   Evil is not an external force controlled by the devil, but rather the potential for evil resides within each person. Man has the potential to exhibit great kindness or to rape and pillage. In the novel Lord of the Flies, William Golding deals with this evil that exists in the heart of man. With his mastery of such literary tool as structure, syntax, diction, point of view and presentation of character, Golding allows the reader to easily identify with each character and explore the novel's main theme, the constant internal struggle between the forces of good and evil.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Golding's novel has a "remarkably complete and solid structure"(Kinkead-Weekes 15). With the exception of Ralf's dream, Golding' novel follows chronological order. It begins with the boys' arrival on the island. Through the chapters one to four, the tension rises between Jack and Ralf, the two leaders. The crisis is reached in chapter five, "Beast from Water", when Simon comes face to face with the personification of evil, the Lord of the Flies. The tension mounts continually as the story unfolds for "the structure and technique of Lord of the Flies is one of revelation" (Kinkead-Weekes 22). The climax is reached shortly after the shattering of the conch and Piggy's death, when the boys attempt to kill Ralf. After this the story quickly comes to an end with the arrival of the naval officer. Thus the story follows the relatively common path of exposition, rising action, crisis, climax and falling action.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Golding's skilful use of syntax is also quite common. He uses long periodic sentences when describing of the peaceful coral island, shadowed wit... ...at "a clearly focused and coherent body of meaning [is] crystallizing out of every episode" (Kinkead-Weekes and Gregor 15). Lord of the Flies enables the reader to comprehend that the "devil rises, not out of pirates and cannibals and such alien creatures, but out of the darkness of man's heart" (Hynes 16). Works Cited.

Ghengis Khan Essay -- Chinese History Mongol Genghis Essays

Ghengis Khan Genghis Khan, or Ghengis Khan as he is more widely known, was born about the year 1162 to a Mongol chieftain, Yesugei, and his wife. He was born with the name of Temujin, which means ’iron worker’ in his native language. When Temujin was born his fist was clutching a blood clot which was declared an omen that he was destined to become a heroic warrior.Very little is known of Temujin until he was around age 13 when his father declared that his son was to find a fiancà ©e and get married. After several days of travel Temujin and Yesugei came across a tribe of Mongols that were very hospitable and welcoming. Temujin was not there long when he noticed a certain girl, Borte the daughter of the chieftain. She was destined to become his wife. Temujin’s father died when Temà ¼jin was still young, poisoned by a group of Tatars. The Tatars were the chief power on the eastern Mongolia at the time, and long- time rivals of the Mongols. When Temujin heard how his father had died, vowed one day to avenge the death. Temujin left Borte, returned to his tribe, with the intention to declare himself leader. At this time he was 13 years of age. Senior members of the tribe ridiculed his plans; rejected him as chief, and abandoned the youngster and his family to the Mongolian plains. While there were noble lineages among the Mongols, such as Temujin's, they did not enjoy the automatic loyalty of others. Nor did seniority guarantee a position of influence or power. Leadership seems to have often been a more informal institution, open to those with the right to contest for it. As a result of this rejection, Temujin extended his vengeful intentions to his own clan members. Life was very hard for the family. It is related that when Temujin discovered his own brother stealing food from the group had no hesitation in killing him. News that he was a stern leader that would kill his own brother to keep order became widely known. On a hunting trip he was ambushed by an enemy tribe and taken prisoner. While pris oner he killed his guard and escaped. The enemy searched, but excellent survival skills kept him alive until he could meet up with his own tribe. This act of courage spread his name to all parts of the Mongolian plains. Shortly after, another raid by strangers left the family with one horse and very little food. Temujin took chase but could not catch them. During hi... ...y populations were put into action as siege experts, and even the cavalry was a mixture of Mongol and other nomadic groups. The success of the Mongol conquests should also be attributed at least in part to two other factors. One was military intelligence. The Mongols had an extensive network of spies and usually had extensive information of an enemy before they engaged them in battle. The other was their use of psychological warfare. Much is made of the total destruction of cities in Central Asia by the Mongols. What is normally overlooked, however, is that this was more of an exception than a rule. If a city capitulated, Ghengis Khan was usually content to let them be, once their defenses had been pulled down. Only those who resisted faced the sword. This not only wiped out resistance, but more importantly, word quickly spread of the wrath of Ghengis Khan, and many peoples found it easier to submit than to resist. In short, although the Mongol successes may appear astounding, they are explainable by ordinary means. One need not look for some mystical explanation. Indeed, to do so does a disservice to the true talents of Ghengis Khan and the Mongols of the thirteenth century.

Introduction to the Human Body Level 3

Anatomy and Physiology Introduction to the Human body Introduction The human body is such an interesting machine, the way it is structured and how it works is educational. There is so much to learn about the human body and up until today scientists are still under going medical research. There are a lot of questions people would like to know about how their body works. The report will include the following structures: †¢ Deoxyribonucleic Acid (DNA) †¢ An Organelle †¢ The cell membrane It will also evaluate the functions of the following structures: †¢ The cell †¢ Body tissue Body system Findings 1. 1Deoxyribonucleic Acid (DNA) 1. 2An Organelle 1. 3The Cell Membrane 2. 1 The Cell 2. 2 Body Tissue 2. 3 Body System 3. 1 Ultrasound 3. 2 Gastroscopy 3. 3 Similarities, benefits and risks of the two procedures 4. 1 Cloning 1. 1 Deoxyribonucleic Acid (DNA) Deoxyribonucleic Acid is a molecule, which passes down information, required for the growth, development and reproduction of an organism. It is passed from adults to their childre n (offspring). DNA is found inside the nucleus of the cell and due to there being a lot of DNA molecules inside a cell; each molecule must be tightly packed.This then becomes a chromosome. DNA found in the cell nucleus is referred to as nuclear DNA, a human’s complete set of nuclear DNA is called its genome. A genome consists of 23 pairs of chromosomes; these chromosomes together consist of 3. 1 billion bases of DNA sequence. DNA consists of chains called nucleotides. Theses are made up of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order or sequence these bases come in, is due to that specific strand of DNA .Each ladder in the DNA is made of two-linked bases. Only (A) and (T) can link together and (G) and (C) can link together. Adenine and Guanine are purines. Purines are double ringed structures. Cytosine and Thymi ne are singled ringed structures and are known as pyramidines. Each DNA sequence that contains instructions, to make a protein, is known as a gene. DNA is used to make proteins in a two-step process. Enzymes read the information in a DNA molecule and then transcribe it into an intermediary molecule called messenger ribonucleic acid (RNA), or mRNA.Next the information in the molecules is translated into the â€Å"language† of amino acids, which are the building blocks of proteins. (Appendix i) 1. 2 An Organelle An organelle is a discrete structure within a cell, as chloroplast or acentriole. It is characterised by having specialised functions, a usually distinctive chemical composition and an identifying molecule structure: often found in large numbers in aparticular cell. Organelles have specific roles to play in how cells work. Some organelles are separated from the rest of the cell by lipid bi-layers similar in structure to the cell membrane.An example of an organelle is ri bosomes. The function of ribosomes is the assembly of proteins, in a process called translation. Ribosomes do this by catalysing the assembly of individual amino acids into polypeptide chains; this involves binding a messenger RNA and then using this as a template to join together the correct sequence of amino acids. (Appendix ii) 1. 3 The Cell Membrane All cells are surrounded by a cell membrane, and its primary purpose is to keep the contents of the cell all together. Cell membranes are like many other organelles of a cell because they exist for a specific job.This job is to monitor and control everything that enters and leaves the cell. The cell membrane is made up of lipid molecules called phospholipids. These molecules all have one polar head and two hydrocarbon tails according to cellupedia. There are three main classes of lipid molecules, which make up a cell membrane. These classes include phospholipids, glycolipids and cholesterol. The particular amount of these lipids vari es across different membranes. The cell membrane is mobile and moves along â€Å"groves† which are set paths the membrane follow.Membranes are composed phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure. The phospholipids form a thin, flexible sheet, while the proteins float in the phospholipids sheet and the carbohydrates extend out from the proteins. (Appendix iii) 2. 1 The Cell A cell is the smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms, which are the smallest units of matter. There are many different kinds of cells. All cells have a â€Å"skin† called plasma membrane, protecting it from the outside environment.The cell membrane regulates the movement of water, nutrients and wastes into and out of the cell. Inside of the cell membrane are the working parts of the cell. At the centre of the cell is the cell nucleus. The cell nucleus contains the cell’s DN A, the genetic code that coordinates protein synthesis. In addition to the nucleus, there are many organelles inside of the cell, small structures that help carry out the day to day operations of the cell. Organelles are groups of complex molecules that help a cell survive. There are many functions that the cell has to carry out: molecule transport, reproduction, energy conversion and many more.I have chosen to discuss reproduction as one of the cells functions. Reproduction One of the main purposes of human beings and living creatures is to survive. To be able to do this the cells must be able to reproduce. Reproduction allows a species of cells to increase its population and have a higher competitive advantage. Second, sexual reproduction can help introduce genetic variation into specie which can be beneficial in the long run. Example of this might be the difference in looks between individuals. Cells can reproduce in two ways, mitosis and meiosis.In mitosis, the resulting daughte r cell is an identical clone of the original cell. Mitosis is mostly used by somatic cells (cells of the body). Meiosis however, is the form of sexual reproduction and only occurs in gametes (reproductive cells). Mitosis If an organism is to live and grow up it must reproduce. Cell division serves an important role in organisms’ health and growth. Cell division begins with interphase, when the cell replicates all of its genomic and cytoplasmic material and prepares for division. After the cell enters the 4-phased mitosis.To see the similarities between mitosis and meiosis see appendix. (Appendix IV) 2. 2 Body Tissue Body tissue is a layer of cells that perform a function. Different types of tissues have different structures that are specific to that function. Tissues can be held together by a sticky coating called an â€Å"extracellular matrix†. The Latin word for tissue is derived from the verb texere, â€Å"to weave†. The major tissue types in the human body: †¢ Connective †¢ Muscular †¢ Nervous System †¢ Lymphatic The type of tissue that has been selected is muscle tissue. Muscle TissueMuscle tissue contains a number of microfilaments composed of actins’ and myosin, which are contractile proteins. There are three types of tissue: Cardiac muscle, skeletal muscle and visceral (smooth) muscle. Cardiac muscle is found in the heart. The cells are joined to one another by intercalated discs which allow the synchronisation of the heartbeat. Skeletal muscle is attached to the bones by tendons. Skeletal muscle is striated muscle. Unlike cardiac muscle, the cells are not branched. Visceral muscle is found in: the arteries, the bladder, the digestive tract and in many other organs.Visceral muscle contracts slower than skeletal muscle, but the contraction can be sustained over a long period of time. (Appendix v) 2. 3 Body System There are 11 systems in the body they are as follows: The Circulatory system Digestive system Endocrine system Immune system Lymphatic system Muscular system Nervous system Reproductive system Skeletal system. (Appendix VI) The system that has been selected is ‘The Reproductive System’. Reproductive System Females have sex organs of: ovaries, fallopian tubes, uterus and vagina. Whereas the males sex organs are: vas deferens, seminal vesicles, prostate and the penis.In the reproductive system a female needs a male to fertilise her egg. There are two types of sex cells known as gametes, the male gamete is sperm and the females’ gamete is the egg. The females’ vagina has several functions: used for sexual intercourse, the pathway that the baby comes out at childbirth, as the route for the menstrual blood (period) to leave the body from the uterus and for a tampon to be used during the menstrual cycle. The menstrual cycle lasts for around 28 days, during this cycle a egg is released from the females’ ovaries once every month and goes down the fa llopian tubes to be fertilised.If the egg does not get fertilised it dries up and two weeks later leaves the body through the vagina, which causes the female to have her period. A period is forms of blood and tissue from the inner lining of the uterus. A period can last anything up to 5 days or longer. Females will not have a period until they have started puberty; puberty usually starts when females and males are aged around 11-14. If the male and female sex cell are fertilised the egg that is released will not dry up and the female will not have a period. The egg will then make its way to the uterus and grow into a foetus. Appendix vii) 3. 1 1st diagnostic procedure- Ultrasound Ultrasound is a non-invasive technique that may be used during pregnancy for finding out the sex of the foetus and whether there is more than one foetus, ultrasound also identifies the measurements of the foetus. The sonographer, is the person who carries out the procedure, she or he can usually tell you ho w many weeks old your foetus is. The mother usually has an ultrasound twice in nine months, the first at 3 months and the second at 5 months. Usually at the second scan you will be able to find out if the baby is a boy or a girl.Ultrasound can find any complications or problems that the baby might have during the pregnancy. They put a cold gel on the mothers’ bump and press the transducer across the bump to see inside of the belly. Having experienced this procedure confirms that ultrasound is a very accurate method of confirming all of the above. (Appendix viii) 3. 2 2nd diagnostic procedure- Gastroscopy Gastroscopy is used if a person is suffering problems, such as severe heartburn or indigestion. An individual may then be required to have a Gastroscopy. It is a diagnostic procedure that allows doctors to look at the upper part of the digestive system.The doctor uses a tiny camera on the end of a flexible tube which is called an endoscope. It is then fed down your throat and down through the tube that carries your food to your stomach which is called oesophagus. It is then into your stomach. Once in place the camera shows the image onto a screen for the doctor to diagnose any problems. It usually takes between 5-20 minutes to perform the procedure. It is usually performed at an outpatient department, which means you can go home the same day. You should not eat anything for six hours before the procedure as the stomach needs to be empty. (Appendix ix) . 3 Similarities, benefits and risks of the two diagnostic procedures The two diagnostic procedures are only similar in a few ways. When both procedures are performed you get to leave the hospital the same day. Both procedures take no less than 5 minutes and no longer than 20 minutes. There should be no pain in either of the procedures performed. However, Ultrasound does not have any risks whereas Gastroscopy has a few risks. Some of the benefits of having an Ultrasound are: †¢ There are no needles or injections and the procedure is painless †¢ Ultrasound imaging uses no ionizing radiation Causes no health problems †¢ Gives a clear picture of soft tissues, that do not show up in an x-ray †¢ There are no risks Some of the risks for having a Gastroscopy are: †¢ The individual may have a sore throat for a day or two afterwards, this is caused if the endoscope scrapes your throat †¢ Small risk that the endoscope could tear your stomach which is known as perforation †¢ Risk of chest infection or pneumonia is slightly higher than normal †¢ When the endoscope is removed your likely to gag or rench (Appendix x) 4. 1 Cloning This is the topic which has been selected to discuss.There are 4 types of cloning: Recombinant DNA technology or DNA cloning, reproductive cloning and therapeutic cloning. People are most familiar with reproductive cloning when it comes to talk about cloning. Reproductive Cloning Reproductive Cloning is a technology used to generate an animal that has the same DNA as an existing animal or a previous existing animal. Scientists transfer genetic material from the nucleus of a donor adult cell to an egg whose nucleus has been removed. The DNA from the reconstructed egg must be treated with chemicals or electric current in order to stimulate cell division.This process is known as â€Å"somatic cell nuclear transfer†. Once the cloned embryo reaches a suitable stage, it is then placed into the animals’ uterus where it continues to grow until birth. Scientists have bee cloning animals for many years since 1952; hundreds of cloned animals such as sheep and cows exist today. Scientists are hoping to be able to use cloning by generating tissues and organs to use for transplants. To do this the patient waiting for a transplant, would have DNA extracted from their body. This would then be inserted into an enucleated egg.After the DNA starts to divide, embryonic stem cells that can be transformed into a tissu e would then be harvested. The stem cells would then be used to generate an organ or tissue, which is a genetic match to the patient Reproductive cloning is contentious as it seeks to create a duplicate of an existing animal. Until the birth of Dolly the sheep in 1996, there was doubt that this would work in mammals, but now some scientists are trying to clone a human. Many ethical arguments against human cloning are caused by misconceptions.Many people seem to think that clones will have the same sort of characteristics and personalities as the person from which they were cloned. Also some people seem to believe that clone will be both physically and behaviourally the same as the donor. Many people also believe that cloning would lead to the loss of individuality however; cloned people have their own personality that is dissimilar from whom they were cloned according to the House Judiciary Committee.

Past Meets Present: Archaeologists Partnering with Museum Curators, Teachers, and Community Groups Essay

Anthropology Statistics Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In Archeological excavation retrieval of intact artifacts or remains is quite a challenge.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Archeology is the study of remains of human or animal or remains of human culture. It is very important in putting together the events of the past. It has helped to authenticate both written history and unwritten history. In itself, archeology has been central in discovery of history of human culture in the pre-literacy period. Man has been able to discover the hidden information that could not have come to surface were it not for the art of archeology(John Jameson J. E., 2012). Archeologies involve excavation, dating of remains, reassembling of found remains to understand the context of their use in human history. Today several theories have been put forward to explain about the origin of man. All these versions have been depending on the archeological studies to justify itself. The most surprising is that archeology has helped strengthen some beliefs more than others(Insoll, 2007).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   No one has been able to refute biblical stories on the basis of archeological studies. Through archeology remotely written scrolls that prove the historical facts outlined in the bible. It has therefore enhanced the authenticity of the claims. There are numerous features that are put together to be able to get accurate morphology of the body remains found in an archeological site. The main concern of archeologist is the morphological features and changes that take place. All the skeletons and artifacts recovered from an archeological site are recorded in a systematic manner which makes access to them easier(John Jameson, 2007). In recoding this information, the name of the site, the identifier of the skeleton, an access number, and type of bone found, the segments of the skeleton found, completeness score and number of fragments. The level of surface preservation is also vital. The bone can also indicate different pathologies that the pers on suffered while alive. There are different cultural practices when it comes to disposal of dead bodies some bury while others cremate partially before burial while some groups cremate fully. All these practices have an effect on the remains found at an archeological site(Hanne Andersen, 2013).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Human history is quite important in understanding the modern day pattern of genetics and human settlement, ideological evolution and culture. Archeologists have to apply a lot of skills to ensure that they are accurate in their reconstruction, dating and inference. When the word archeology is mention many only thinks of a group of people who are only interested in digging up graves and ruins but it goes beyond the excavation(John Jameson, 2007).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The items that were used in the remote culture do not necessarily resemble the modern day tools and items. It takes a lot of study and brainstorming to find the purpose of a tool found at a site. The erosions and continuous formation of soil has made discovery of an archeological site quite difficult(Hanne Andersen, 2013). In fact most archeological site that has lavished our modern Museums was discovered by accidents. Very few had an intentional discovery. The floods and sedimentation and soil formation over years had been responsible for deeper and deeper burial of artifacts and remains of animals and human ancestry(Nicholas, 2010). This conceals the site completely leaving no clue on the surface(Nicholas, 2010).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As soils, rocks and materials sediments on the remains they act stronger forces on the remains. Other forces of nature that acts on the remains are exposed while at surface area also leaves effects of the remains. Unfortunately, these forces can destroy the artifacts and remain by modifying the structures and the morphology. Though the archeologists have used shapes of the modified skulls excavated from different sites to reconstruct the living morphology of the humans, it may be possible that the shapes discovered are not original and might have beendeformed by the pressure from the overlying soil and rocks(Stottman, 2010). Pieces of artifact of remote settlement are reassembled together to find out how the object looked but accuracy is still questionable. Various archeological objects discovered from various sites are rarely found intact.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The cause of the damage is varied and the cause of the archeological material are also numerous. The forces responsible for the disintegration of these materials include physical forces such as damage by stray wild animals, domestic animals, sunlight, rainfall, wind and cyclones. Long exposure to these environmental forces can further damage the materials hence losing evidence of cultural heritage. Depending on the culture of a particular people, human remain were others were disposed through different methods. Thus somebody remains were buried while others thrown in the remote areas. This exposed the bodies to wild animals that tear apart the body part leaving little clue that may be less helpful in reconstructing the body morphology(Peter Bleed, 2013). The practice of dead body cremation has been practiced for quite a long time. Though the partly charred bones found in such archeological sites helps deduce the cultural practice, it conce als the evidence of what type of people lived in the archeological site. Using carbon dating may also be altered as the burning may reduce o the accuracy of the dating(Insoll, 2007).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Time is also an important factor in the level of preservation of archeological material. Most of the remains of the remote human culture were not made of durable material. Even those that were made of metal were made of unrefined iron. When unrefined iron is exposed to earth for long it degrades and absorbed into the earth. The other material made from organic substances suchas wood, hides and skins easily undergo decay over time. In order to get information of the archeologist at the archeological on such material, a lot of care is required on the part the archeologist. They have to trace the impression by decayed material then infer from the impression what the artifact might have been. In doing an inference from an impression, it is obvious that one cannot be certain of its accuracy.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In consideration to human history, man has used numerous methods to preserve the dead bodies. The civilization of people who once lived in a particular location also play a role in determining the intactness of an artifact or body remains. Burial boxes and built tombs offer some resistance to the force of the earth pressure exerted on the remains hence reduced destruction of the remains. This makes studies easy and also determines the durability of the remains in the Museums where they are kept(John Jameson, 2007). Greater role is expected of the authorities that protect the archeological heritage. They should be guided by principles that that are thoroughly researched and successfully used elsewhere. It should be remembered that degradation continues despite excavation and transfer of the artifacts and remains to the museums(Nicholas, 2010).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the General Conference of United Nations Educational, Scientific and Cultural organization, it was noted that the preservation of the archeological sites, monuments, artifacts and remains depend on the affection that people has for them. The handlers of the artifacts of the sites and remains must develop passion to prevent further disintegration. The wish of the member countries to develop science was found to have great role. The contemplation to do further study in works of the past strengthens the understanding and cooperation between countries to protect archeological heritage. This further strengthens the fulfillment of the social mission(John Jameson J. E., 2012).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   We will explore the data from a website on archeological human remains and consider each of the bone found in the site. The percentage of completeness is likely to nullify or prove the hypothesis on the subject.The data set is for human remains that were recovered from sixteen different archeological sites in Northumberland and Durham. The human remains are kept at the Great North Museum in Newcastle, Wintergardens and Sunderland in Sunderland and Roman fort. The rest of the skeletal material was taken to a laboratory for testing in Newcastle(Nicholas, 2010).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   From the database of this skeletal material an analysis was done to determine the fragmentation and completeness of the material remains.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Below is a graph on the distribution of the remains according to the site where they were collected.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   . The number of skeletal material collected per Acheological site   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The skeletal materials were collected from various archeological sites and each site had a god number of material collected.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   To do an assessment on the surface preservation is quite subjective. The evaluation of the surface is a good determinant of the age of the organism at time of death. It is also important in assessing the pathologies, sex and the age at death. The preservation is partly a subject of age. The ossified bone are well preserved over many years while poorly ossified degrade quite fast with time. The size of the bone is a subject of sex of the person(John Jameson S. B., 2007). The taphonomic processes such as excavation, burial environment, curation has an impact on the condition of the bone and the bulk of skeleton that will be recovered from a site. Excellent preservation means that there is no surface erosion while poor preservation shows poor preservation. The level of preservation along with the completeness has an effect on getting information from the material.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The excavated remains preservation per site of discovery in the graph in fig 2   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Fig. 2 Distribution of preservation levels of the skeletons   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Key to figure 2 0= Exellent, 1= Very Good, 2 = Good, 3 = Fair, 4 = Poor ,5 = Extremely poor ,6 = Burned bone   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Where cremated remains were examined they were described by their appearance L= Longitudinally Split, T= Longitudinal and Transverse Checking C= Cracking, W= Warping (Michelle Gamble, 2012)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The level of completeness of the human skeletal material collected were the compared based on the percentage of the complete whole of the remains and the following were the results. Level f preservation varied from one remains to another and also from one archeological site to another. Not all the bones were fully preserved neither were they all poorly preserved. At least each percentage of preservation were represented (see key for reference). Table. 1 Frequency for completeness of different % complete Frequency Percent Valid Percent Cumulative Percent Valid 22 2.4 2.4 2.4 ? 1 .1 .1 2.5 1 307 32.9 32.9 35.3 2 167 17.9 17.9 53.2 3 346 37.0 37.0 90.3 4 91 9.7 9.7 100.0 Total 934 100.0 100.0 ?= Undefined 1 = 75% 4 = 100%   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   From the table it was noted that only 9.7% of the remains were 100% complete. This meant that more than 90 were fragmented, burned or decayed. This proves how much of the material were deformed hence identification had to be done through inference. The deformation might have been due to the pressure of the underlying soil or from physical forces. This data set also composed of the charged and burned body remains (Peter Bleed, 2013). These might have had an effect on the percentage but this is less significant as not most of the remote cultures cremated the dead bodies.The bar graph comparing the level of completeness is as in fig 3below. Fig 3 Key Y axis ?= Undefined 1 = 75% 4 = 100%(Michelle Gamble, 2012)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The percentage completeness was in different frequency. The collected remains had different level of completeness of the fragments. Each level of completeness was represented showing that the fragmentation is significant in all remains what varies is the degree.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Fragmentation also has greater effect on the artifacts. The fragment increases work in analysis of the archeological remains. The archeologist has to identify part of the fragment from numerous fragments then use then to reassemble the bone or the artifact. This can be quite challenging especially when parts of the same bone to be reassembled have decayed completely and is not traceable any longer(Stottman, 2010). This may be quite difficult the probability of reassembling unlike fragments is high. The connecting of wrong fragment has an effect on the morphology hence losing the right shape of the organism or objects. A wrong conclusion is made hence conceal the culture and body morphology of the organism. The fragments were recorded some in terms of weigh and some in terms of numbers. Fig 4. No and weight Fragments collected at the sites Note   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The figures in the Y axis without units are the number of fragment while hose with units are weight of the fragments. The data set was not recorded in uniform units but is helpful for the comparison(Michelle Gamble, 2012).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The graph portrays the occurrence of a number of fragments and the weight of each fragment and the number collected from the sixteenarcheological sites.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Some of the bones were segmented. Some only part of the segments were found at the site Figure 5. Table of the Bone and the segment recovered   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The table above is a plot of the bones and the corresponding type of segment collected from the archeological site. Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Most of the human skeletons collected from the sixteen sites have proved over 90% of fragmentation and fragmentation. This trend is similar in other skeletal material from archeological site, the same phenomenon happens with the animals remains, material artifacts of remote human culture. Therefore fragmentation is a great setback to the archeologist in getting right information for scientific and historical inference. Most of forces and conditions responsible for this are not preventable but human error during excavation may be avoided. With careful marking and excavation, the relevant information retrievable from material remains can be increased. Marking and protecting of identified archeological site is necessary.

Outline How to Prepare for Winter

Title: Surviving winter Specific purpose: How to prepare for winter I. Introduction A. Attention Materials: Did you know on average Minnesota gets 50 inches of snow a winter. Accroding to Minnesota dept. of Natural resources. â€Å"The twin cities are the coldest major population center in the United States, with an average or zero degrees or below 64 days each winter. B. Tie to the audience: I’m sure all of us have experienced winter. Whether it was extremely light or extremely brutal. Being prepared is important. C. Creditability material: Well I’m from Minneapolis, MN, where winter is extremely brutal.We have heavy snow, temps below zero, and wind chills in the negative. So being prepared for winter is something I know about. D. Preview: I will explain three basic things, How to dress in the winter, how you can prepare your vehicle for winter, and how to winterize your home. II. Body A.
