Natural Selection - Lab Report Example eby the trait of interest has an optimum value, and finally, Disruptive curve in which organisms that have the largest and the smallest values of any given trait boots of highest fitness value and conversely, organism that have intermediate values are disadvantaged. Considering the above stated facts, it is seen that in the long term, Directional selection results to generation of the new type of species from the existing species. This is unlike stabilizing in which the given specie maintains its existing type without any variation over the long period of time. It has been found that stabilizing selection results in the refinement of the existing specie type. On the other hand, disruptive selection facilitates favouritisms of given individuals of a given phenotype (Williams). This experiment’s main objective is the comparison on how the population size varies in different generations depending on different environmental conditions, determination of the effect of different predator types on the population of prey, and the gaining of graphing and interpretation knowledge. In this habitat, the number of Clothespin is increasing linearly while knives and spoons are decreasing as the generation changes. However, number of spoons decreases from first generation to second generation, then it starts increasing. In this habitat, the number of S. pea preys decreases tremendously in all the generation. The number of White and pinto decreases from first generation to second generation and starts increasing from generation 2 to generation 3 The number of Forks and clothespin in this habitat is almost constant. The change in the number of spoons increases tremendously from generation 1 to generation 2 and decreases from generation 2 to generation 3 As the Number of predators increases, the number of preys decreases. This is due to the fact that an increase in the number of predators results into more preys being eaten and as a result, their (prey) number decreases. Also,

The Arab experience in adapting to American society Essay

The Arab experience in adapting to American society - Essay Example I was very happy when I was accepted in the UNC to finish my studies there, I had been hoping very much that would be admitted there because I had heard a lot of good things about the university, I have never met anyone who has been to the school but in the internet people say it is a good place. I hope it will be good for me so I can finish my studies in America before I go back to my country so I can continue with my dream of becoming a great general like my father. I also am glad to be in the university because that means I will be studying with other students who are good in speaking English as their mother tongue so I will be able to learn how to speak it very well from them. Back home, my main hobbies were playing football and taking trips and travelling, I used to spend a lot of time driving my parents car and even went outside our town to explore, sometimes I could use a bike. In since primary school I have played soccer with my friends and I spend a lot of time in the field, I play the position of a defender. Back home, we watch American football on TV and I think it is very good, I hope I can get a chance to play, because of my army training I am sure I can be able to learn the game quickly. To me the chance to study in a great American university is very important because I have always wanted to study here, when I was young we would read textbooks showing big cities and roads in America and I would say that I wanted to go and visit one day and maybe study.Because of that, coming here to me was like a golden chance.... run many kilometers in the hot sun and practice matching for a long time, however since I wanted to be like my father, I persevered and I was able to become successful. However I decided even if I wanted to become a general like my father, I should travel and acquire more knowledge which I could use in life later as well as their skills not limited to military ones. Because of this, I moved to the United States after I got a scholarship and in January 2012 I came here to America and registered in Fort Collins where I studied English so I could improve my communication and reading skills as well as be able to study other subjects in America. This was however very difficult for me since Arabic was my first language which I had spoken all my life and it was very different from English, and writing and learning the alphabet and letters of English was hard and it took me almost on and a half years to finish the course and even if my English is still not very good I practice every day and I talk to a lot of my Americans friends so I can learn it from them. This is because the best method to learn a language is not by going to school but by using it through speaking to people who understand it well. I discovered that in America most people are christens but very many also have other religions and some do not have religion at all. In my home country, this is very different because almost everybody I know is a Muslim, I was taught since I was a child to love god and respect other people and their faith even it is different from mine. This is easy in America because people do not treat me differently because I am a Muslim, in fact everyday even here I go to a mosque every day for prayer, this is enjoyable because apart from prayers I can meet other Muslims and we can talk and

Response Journal 5 - Essay Example According to the CNN article, Transocean, the owner of the rig is blaming BP for its missteps which caused the spill. In the said article, Transocean pointed out that the explosion was the result of "a succession of interrelated well design, construction, and temporary abandonment decisions" that "compounded the likelihood of its failure," (CNN). If the claims of Transocean are true, we can conclude that an engineering decision was partly to blame for the spill. In fact even BP’s investigation revealed a failure in engineering design. As we all know, this spill caused widespread harm to the people, the environment and the wildlife of the region. A major implication of the engineering decisions in this incident is its effect in the environment. Marine life has been largely devastated. The aquatic food chain was disturbed causing the death of a multitude of organisms, several varieties of fish and other sea creatures. The economic implication of the spill is that the people whos e livelihood depends on the ocean now risk losing their means of survival. The social implication can be seen in how the spill affected the health of the workers at the rig and the people within the vicinity. Another important implication of the engineering decisions that led to the oil spill is in the area of politics. Government must have the will to restore the Gulf to its previous healthy condition.

Middle-aged and older people observation Essay Example | Topics and Well Written Essays - 1250 words

Middle-aged and older people observation - Essay Example It is well known that no two persons are alike and I have found the same in almost every body but the most significant and identifiable aspect what I found is that the people within a particular age group tend to behave in almost the same manner. This almost similar behavior might be due to similar socio economic background from which they come from. Some of the middle-aged people coming from somewhat rich background tend to behave in a more dignified manner even though they are older than the people who are from a poor background. With this observation what I really came to know is that older people who lead significantly decent life through ought their life have a deeper understanding towards their life and will try to act accordingly in public. On the other way round poor middle aged and older people do not try to behave accordingly in public and according to the situation. On older people there past life influences their present state of behavior a lot. I have observed six people who are all above fifty-eight years. The first person I have observed is an old man who has retired long back from Military Air force. He has receding hairline and is slender built but very active, red in color, very lively person and pretty intelligent, was very communicative, very popular among the people coming to the library. I was observing this person from almost a week and could gather most of the information related to by simply over hearing the discussion between their old friends in the public library. Since he was worki ng in Air force earlier he is quite informative and communicative too. He has three children and all are working but no one is yet married. Being slender built he is very energetic and his actions are not at all like an old man. He even helps his fellow old men in climbing stairs. He is very popular among women coming to the library. He discusses all issues going in his home and even enquires about others

Parenting Model Metaphor - Assignment Example Parents must be strong, patient and flexible travelers who would adjust to the situation given to them. Later towards the end of the journey, the parents would see in their golden years what kind of travelers they were. There is no course or learning program for people who would be parents one day that is why it is difficult to assume the role. It is a wonderful adventure yet quite fearful since many unexpected things can happen along the way. The important thing is to be prepared that is why married couples planning to have children must be able to settle their individual differences and adjust to each other before having a child. Each parent have different family background and experiences unless they share similar cohort ( classmates, next-door neighbors, childhood sweethearts) whose lives have been fused by their growing up experiences( Chapter 12). Nevertheless, they have their own individuality that would highly influence their decisions as they have witnessed and experienced from their collective efficacy. In short, the traveler’s backpack is already filled with their individuality that would soon come out along the journey of parenting. As they pull-out from their bags their own experiences to deal with situations (i.e. my mother taught me that the best way to cure fever†¦..) their child would absorb from them such ideas and experiences too. A bag filled with bitter, resentful, and painful life experiences would make the journey hard for the parent unless he/ she use them to teach life’s lessons and give hope to their children. The traveler’s also need to bring with them food on the journey to nourish their children with. These food are the family rituals, celebration, traditions and routine which according to Friesen helps † families establish habits that can help them succeed and connect on a regular basis. The familiarity of repeated activities and

Health systems of Canada and Australia Essay Example | Topics and Well Written Essays - 1250 words

Health systems of Canada and Australia - Essay Example Today, every country is expected to devise its own strategies of addressing the three major goals associated with the healthcare system. These include sustaining a healthy population, treating ill people, and safeguarding families from financial ruin that results from medical bills. This paper will compare health care systems of Canada and Australia. The health care system in Canada is comprised of various forms of health insurance policies, which aim at ensuring that every citizen in the country gets access to adequate health care. The system is funded through public means, and administered through either territorial or provincial basis. The federal government is the one that provides the guidelines through which care should be provided (Kliff, 2012). With regard to the health care system in Canada, individuals gain equitable access to medical treatments and preventive care. They can access these services from hospitals, through primary care by physicians, dental surgery, or other medical services. With limited exceptions, all individuals in the country are eligible for health coverage irrespective of their income, medical history, or living standards (Kliff, 2012). The kind of health care system prevalent in Canada is subject to significant political dispute as well as debates throughout the country. A number of critiques question whether the current system is efficient in terms of delivering treatments in a timely manner. These critiques stipulate that the country should implement a private system as in the case of the U.S. On the contrary, the government, policymakers, and individuals in the country worry that a private system would result to inequities in the health care system, as only the wealthy individuals can afford specific types of treatments (Kliff, 2012). The health care system in Australia is multidimensional comprising of both public and private health care providers, participants, settings, as well as supporting

Internet Censorship Essay Example for Free

Internet Censorship Essay WebInternet censorship (Is it possible to keep children safe from potential internet dangers? ) by: Eko Setiyo Utomo The Internet has become a part of modern life style for most people. In developed countries, most people use the internet at home. Children can access the internet for everything, from playing games, to doing schoolwork, to chatting with friends via e-mail, to surfing the web. Most online services provide children with a vast range of resources such as encyclopedias, current events coverage, and access to libraries and other valuable material. However, there can be real risks and dangers for an unsupervised child because most materials on the Internet are not only uncensored but also unedited. Adults can be expected to make their own evaluations of what they find. Children, who lack experience and knowledge, can not do this. Strohm (n. d. ) claims that the essential issue in the internet is internet pornography, which is a topic debated by many experts, but many other issues dangerous to children are of concern too. Children who have access to the internet can easily be lured into something dangerous. As stated by Manista (2002), â€Å"censorship on the internet has become an issue for a number of very specific reasons†. Parents should not assume that their children are safe online from internet dangers; and they should not just rely on soft ware to protect their children. According to Schwartz (2004), using filters to block access to undesirable materials may never prove to be the solution. In addition, governments should have the power to decide what is not acceptable for the minds of children. In contrast, it is argued by some people that supervising access to the internet could limit the creativity of children. n addition, according to Males (2000), statistical evidence does not support to filter the internet. He describes that several kinds of sex offences has declined since period internet (1990s) access in America. This essay will investigate the unsuitable nature of much of the material on the internet for children. It will also examine the devastating and lasting e ffect of pornographic images on children. Thus, parents must play a key role to keep children safe from potential internet dangers. Finally, it will suggest that parents should teach children how to choose suitable materials on the internet. The first section of this essay will explain why internet pornography and some of the various resources unsuitable for children can have a harmful effect on children. The next section will maintain that soft ware is essential to protect children from site danger. Finally, this essay will argue that parents themselves should be aware of the dangers on the internet. It is important to recognize that pornographic images on the internet can have a devastating and lasting effect on children. Children using the internet unsupervised can view free pornography pictures through accidental accessing. Strohm (n. d. ) has claimed that it is a commonly held belief that pornography on the Internet presents a serious danger to children online, and that the effects of pornography are progressive and addictive for many people. He further points out that most pornography sites are very easy to find. These sites always invite children and teens to take part in exposure. Children using internet chat rooms are the main target of sexual predators, often with traumatic results (Nuss 1999). Pornography isnt the only thing parents dont want their children to see on the Internet. Parents are also concerned about anarchist, Neo-Nazi, and all sorts of other propaganda, as well as information on computer hacking and building explosives. There are hundreds of thousands of web sites promoting illicit activities. However, many individuals and organized groups at the same time are attempting to protect children from information on homosexuality, violence, drugs and alcohol, hate speech, and the environment. In addition, according to Males (2000), children can become victims of internet crime, such as pedophile contacts with children and child pornography distribution. It is possible that some children may be visiting internet sites and communicating with potential internet predators without parent know. Otherwise, some pornographers argue, â€Å"In the right hands porn has its place. As anyone in the industry will readily proclaim, millions of men and women enjoy Web erotica harmlessly, and some couples turn to porn to enhance their sex lives† (Jerome et al. 2004). Children may have the opportunity to become informed about adult lifestyle. Pornography materials on the internet or ther media can be a valuable educational tool for children to understand about the concept of sexuality (Reisman Ray 1999). Furthermore, according to Males (2000), the internet access period (1990s) does not seem to have brought about any particularly bad effects. Nonetheless, children have access to computers and the internet not only at home, but in many other places, what they choose to view is very difficult to control. It is a concern of many parents that fre edom of information presented by the internet can pollute their main of children. Many kinds of methods have been implemented to avoid some of these negative effects of the internet. First of all, School on the Web†, for example, is a program has been developed by Microsoft and MCI to assist many schools attending information about education world on the internet. Moreover, Cyber Patrol, a popular soft ware, is a soft ware program that contains a twofold filtering technique. It can block unsuitable sites from a list of restricted web addresses (Reeks 2005).. Others products are Bess/N2H2, CyberSnoop, I-Gear, Internet Filter, Library Channel, NetShepherd. On Guard, Parental Discretion, Rated-PG, SmartFilter, Tattle-Tale, WebSense, and X-Stop. These soft ware are designed to present at one or more many kinds of computers. According to Schrader (1999), these products offer five basic approaches bad word, bad site, bad topic, site content rating systems and bad service to control expressive content on the internet which may be set by the individual user or built into the program. In addition, children using the internet can also be prevented from disclosing their personal details via e-mail or chat room with the application of soft ware, such as Net Nanny. Meanwhile, The Platforms for Internet Content Selection (PICS) provides particular-labeling vocabularies, which work in different way to filter, to block inappropriate materials. According to Resnick and Miller (1996) the parent, as a user, can select every material in the certain label that is provided by software to block unsuitable sites. Nevertheless, it is an impossible task to be able to censor everything on the internet because the internet is an infinite global network. Males (2000) maintains that the internet would be a useless tool for students if it is blocked, or filtered. Filters can easily block student out of websites that they need to access for research simply because they contain words that have been flagged as inappropriate. He also believes that People who worry about the internet have a phobia or anxiety disorder which is not concerned about real problems. However, using appropriate soft ware can help to minimize the negative effects of the internet, even if many weaknesses exist in various software. Parents can play a key role in helping young people to be aware of the dangers and can get practical help on keeping children safe online. Governments especially, which have the power to decide what is not acceptable for the eyes of children, should make many regulations to help parents to keep children safe from potential internet danger. In late 1999, the Australian Government established NetAlert to provide independent advice and education on managing access to and usage of the Internet (NetAlert 2005). First of all, parents need to build trusting relationships with children and set a good example. Most parents teach their children not to give out information to strangers, not to open the door if they are home alone (AACAP 1997). As a result, it is hopped that children never give their name, phone number, e-mail address, password, postal address, school, or picture without their parent permission. Furthermore, parents should also teach children how to search and find many materials that are suitable for young people (in Healey ed. 2002). Parents are strongly encouraged to speak openly with their children about online dangers and monitor their online activities. Moreover, it is important for parents to be aware that they can not assume that their child will be protected by the supervision or regulation provided by the online services. Only parents can judge when a young person is mature enough to access the internet. Nuss (1999) also claims that children will be much safer accessing the internet if parents take the time to learn to use the internet first. However, children often feel that as Internet users, they know how to make a decision about what materials are harmful. Moreover, when students are exploring the Net for different kinds of materials, they are essentially exploring the real world (Singhal 1997). The internet is one of the contexts in which young people can discover themselves, what is normal and abnormal in their behavior (in Healey ed. 002). However, because most children do not understand what materials on the internet are real or just imagined, parents should not trust children to use the internet without supervision. In conclusion, the internet is a valuable tool for assisting in the education of children. However, when children are online, they can easily be lured into something dangerous. Children have access to online information that promotes hate, violence and pornography. These can influence their behavior and even be harmful. Filter soft ware is the most effective way to protect children from inappropriate materials on the internet. Therefore, parents, who play a key role, should talk to their children about what is online and what might happen online. Finally, the government should use its power to control those sites that provide unsuitable material for young people.
