Lord of The Flies Book Report :: Book Review

Character Page Ralph Ralph is a fair boy of about twelve. He is the first character introduced in the story and is a dominant leader throughout most of the book. He finds the conch, a symbol of order and authority. He blows the conch and holds an assembly in which he is voted chief. Ralph stays focused on getting rescued and building shelters while most of the others play and hunt. By the end all the boys have either turned against him or died. Piggy Piggy is a large, timid boy, with asthma and specs (eye glasses). He is Ralph's loyal sidekick from the start. His brilliant mind and logical thinking are trapped inside his unattractive body. He is disrespected and rejected because of his looks, and used for his glasses, which are the only means of starting the fire. Piggy struggles to stay strong and clear through the madness and chaos. Jack Jack is the leader of the choir boys who become the first band of hunters. He is intent on becoming savage and killing pigs for meat. He neglects the fire, their only hope for rescue, and goes hunting instead. Jack rebels against Ralph and forms his own tribe at the other end of the Island. His tribe hunts all day and holds feasts and dances every night. His violent instincts show up in murder and destruction as civilization runs out of him. Simon Simon is mysterious and spiritual. He is a small boy with incredible, silent, courage and strength. He starts out a part of Jack's choir, then becomes loyal to Ralph when he is elected chief. Simon helps Ralph with the shelters and is admired by the littluns. He has a spiritual encounter with the Lord of the Flies, which is a pig's head on a stick. This encounter is one of the most symbolic incidences in the book. The head is the beast that all the littluns fear and represents the inner instincts and evils in man. Samneric In the beginning Sam and Eric are recognized as two separate people, two twin brothers. By the end they are referred to as Samneric, a single being. They were loyal to Ralph in the beginning and throughout most of the book. Towards the end they are captured by Jack's tribe and join in on a hunt for Ralph. They are weak and easily swayed by forceful power. Plot The book opens with the description of a beautiful island with pink rocks, warm pools, and a long, palm lined, beach protected by a coral reef.

Cloning, Triumph or Tragedy? Essay -- Argumentative Persuasive Clone G

Cloning, Triumph or Tragedy? The creation of life through scientific experiments is not a new concept. The idea has been in existence as far back as two hundred years. Mary Shelley was far ahead of her time when she brought the human like creature to life in her writing of "Frankenstein, The Modern Prometheus." The story of "Frankenstein" was written as a myth, yet it continues to leave the world intrigued today. The idea of creating human or animal life is now in the making, except there is a twist to creating this new life. It is known as cloning, bringing an exact replica of cells to life to create an animal or a human that is already in existence. Though human life has not yet been a part of cloning, the cloning of one lamb has recently occurred. The advantages to cloning as well as many ethical dilemmas will be discussed, According to one document, "The technology to clone is simple, though far from perfect." Various views will also be shared from J. Michael Bishop ¹s"Enemies of Promise." Scientists will express their beliefs in the advancement of technology and the use of science in today ¹s world. Many definitions of cloning have been brought to light by groups and organizations. The American Medical Association defines it as "the production of genetically identical organisms via somatic cell nuclear transfer." Cloning is the method of producing a baby gene that has the same gene as its parent. The idea of cloning all began in 1997 with embryologist, Ian Wilmut, from Roslin Institute in Scotland. He and his colleagues were the first to clone a lamb they named "Dolly." Before this experiment was proven successful, cloning was thought to be an impossible endeavor. It is true that the technology to clone does exist, but ... ... it is human failure that causes problems in our society. People need to think harder about the reality and the effects cloning could have on society before cloning itself becomes real. If human cloning ever does become legalized and takes place, I surely hope that science doesn ¹t take the bad  ³rap ² for it, but the failure of humans instead. We saw Victor Frankenstein ¹s failures, we saw other accounts of failures. Maybe we should learn from the various examples, that human life is extremely fragile and to distort it could change the human race forever. Works Cited Bishop, J.

How Important Is It to Maintain Confidentiality in a Childcare Setting? Essay

How important is it to maintain confidentiality in a childcare setting? When in a childcare setting it is vital to maintain confidentiality in different areas not just for the Child’s welfare but the families as well! Confidential information must not be shared outside of the setting E.G family or friends. The following examples are to be kept confidential; enrolment forms, family’s health insurance information, health screenings and records, including immunization records, emergency contact information, contact information for those authorized to pick up child, emergency care consent forms , consent forms (permission slips) for outings or special activities, names of regular medical or dental providers who know the child, nutritional restrictions, progress reports, child observation logs, parent conference logs, medication logs, documentation of medical, behavioural or developmental evaluations, referrals or follow-ups, addressing issues relevant to the child’s participation in the program, documentation of any injury occurring at the program site and the steps taken to address the situation. While the rights and desires of families to keep their personal details private are important, there are also some circumstances under which identifying information should be shared for example; Program staff and the â€Å"need to know (might have a dietary or medical requirements so the cook or nurse will need to know) Outbreaks of reportable illness or Outbreaks of reportable illness as the information might be vital and used to saved the children’s life or keep them healthy. One way to differentiate whether the information is confidential or not would be to think â€Å"Is this common knowledge or do I know it because my position in the setting† as all children, families and young people have a right to confidentiality. So always ask your supervisor if you aren’t sure about what information is appropriate to disclose to different people. In addition all information needs to be store properly- in a secure place. If this isn’t possible make sure you donâ €™t discuss the information apart from those directly responsible for the care of the child. Technology is advancing but this still doesn’t escape the laws. Read more:  Maintaining an Individual’s Confidentiality and Disclosing Concerns There is legislation that defines in what ways personal information can be used; The Data Protection Act 1998 (was created to protect individual’s rights and to prevent breaches or information.) It applies whether or not they are kept on the computer Maintaining confidentiality protects children and their families from gossip but also prevents situations of an abuser mounts a legal defence based on tampering of evidence so it is essential that you don’t talk to anyone other than those directly involved about your concerns or about what a child has told you. As anything you learn about children or their families or other during the course of your practice is likely to be very confidential. When working with other professional it is most likely you will hear comments and remarks that aren’t anticipated to be repeated outside of the meeting/ conversation. You may be given documents that cover sensitive areas- this means that you need to keep the information confiden tial but also in a safe and secure lock up. Photography is an ever increasing technology and can be a brilliant way to have evidence for observations or practical’s but there are some basic rules that you have to follow to maintain confidentially when taking photographs; ALWAYS Have permission from the parents of the child that you a photographing, Only use a school camera as this ensures that the photographs don’t make it out of the school, although the parent says it okay the child might not when you are taking the photo always keep this in mind, If the parent(s) don’t want their child to be in the picture then make sure that they STAY OUT of it or you can cut/ bur them out of the photo. When doing observations you need to maintain confidentiality in the following ways; only using the Childs first names, change the children’s names if they are unusual or could lead to the child be identified in any way, give the type of setting rather than the name of the settings EG â€Å"a primary school† rather than â€Å"The John Warner primary school†. Write the children’s age as years and months rather than the date of birth as they can be easily identified, photographic records should not be used unless permission is gained from the child’s parents and the setting lastly make sure the files have a contacting telephone number so they can be returned safely if lost. Lastly it is vital that as a practitioner that we maintain confidentiality as our main priority is the welfare of child and their development. If you breach confidentiality then you are putting the child at a very high risk, whether this is of kidnapping, sexual, emotional or physical abuse, there are laws and moral rules for a reason as it should be the child’s interest at heart at all times. Secondly you should always maintain confidentiality to keep a good relationship with the parents. You are in charge of the apple of their eye and they are trusting you with the Childs life thus it is vital to maintain a good and healthy relationship with the c hild’s parents. If you don’t this might result with them taking them out of the current school and you losing your job. Overall you should always make sure that the person who is picking the child up has the right of access as this could lead into very bad situations of the child being abducted. It is vital that you don’t break the trust with the family. The child might suffer abuse so you should take the right steps (Talking to your child protection officer) and no one else unless directly involved with the child’s welfare. When passing on information make it is to the correct people as the child might not be telling the truth and putting the child and family in danger for no reason. Don’t repeat anything your team says that you think is confidential. If you hear something that is being talked about them distract them- if it is a parent just talk to them about how well their child is doing but if it is a member of staff take them to one side and talk to them. With any serious or sensitive issues with children ( break ups, deaths etc†¦) then you need to tell your supervisor immediately and instead of asking the child to tell you a good way to get their emotions out is to write it down ( if old enough). Always ensure that children’s names are remained confidential e.g.; in observations etc†¦ If you are going arrange to talk to anyone about a confident matter then always arrange a confidential area so no one will come in and hear/ see what you are discussing. Always obtain permission for photographs/ videos of a child. Make sure there is no mistrial as to many questions could lead a child on and not tell the truth, get a professional in to deal with the matter. Lastly the data protection acts has 8 principles that state all about maintain confidentially with any documentation in any situation, this is the law. Overall it is vital that you as a professional practitioner you always maintain confidentiality of the setting/ children/ families as it can put many people at risk or a endless list of dangers.

Researching a one company and Solving 3 Questions Essay

Researching a one company and Solving 3 Questions - Essay Example McKnight’s management principles were firstly to delegate responsibility and to encourage staff to exercise their initiative and secondly for management to learn to focus on supporting staff who have participated in failed projects move on to something else rather than punishing them (â€Å"McKnight Principles† 5). To reinforce its culture of intrapreneurship 3M has instituted several policies and philosophies. The three that jump out of 3M’s organizational culture are the 15 percent option, tolerance for failure and rewards for success. The 15 percent option give employees authority to 15 percent of their workweek on individual projects of their choice without the need to either disclose or justify it to a manager (Govindarajan and Lang 3). This policy gives 3M staff freedom to be innovative. Tolerance for failure philosophy guarantees employees their jobs and no punishment for a product that fails in the market. On the contrary, 3M has often repeated stories of famous failures that went on to become highly successful products. This policy has the effect of keeping initiative and creativity alive among 3M’s staff. For innovative products that go on to have a breakthrough in the market, 3M acknowledges team member through salary raises, promotions, and recognition. For example the Golden Step award is given to team members if a newly launched product reaches a revenue goal of $2 million in the US or $4 million worldwide (Govindarajan and Lang 3). Better yet the informal recognition given to successful entrepreneurs through stories that convert them from mortals to legends is considered more powerful by 3M staff. The two major benefits that 3M derives from its organizational culture are staff loyalty and product differentiation as the key to commercial success. Staff loyalty is a manifestation of high staff motivation which often leads to increased job performance. Having a highly committed staff 3M’s management find it easy to
