Reading stories with children - Research Paper Example I decided to read two different books in terms of their themes and setting. The first book was a religious book with religious themes while the second book was more of a fun book. The interaction with the kid, who is about five years of age, was rather eye opening. During the reading session, the kid interjected the process severally asking various questions regarding the stories. He constantly asked questions regarding the meaning of words he did not understand. This trait was a bit interesting as it portrayed the kid as an inquisitive person who wanted to know more. Various facial expressions accompanied my reading to the kid so as to further make him understand certain aspects of the stories. He was keen on the kind of expression that he saw on my face as I continued to read the books. Whenever there were frowns on my face he could also frown. This was a sign that the kid personalized the reading through the expressions that I was portraying to him as the reader. After reading the books to the kid I did further analysis on his reactions during the time I read the books. This revealed something interesting as I realized that the child scrutinized details of every picture that was shown to him. The scrutiny of the fin details in the pictures portrayed the kid as an individual who is interested in both the pictorial aspects of the stories as well as the word flow. This was even more interesting when it came to recalling the reading on the side of the child when I asked him questions. Even after reading the two stories to the kid certain aspects of his traits were outstanding. The kid was able to recall the outline of the two stories though note as exact or fair as it should have been. The first story was titled chocolate me which talks about the skin color in different people. It was more religious and encouraged the readers to appreciate

Obesity is a critical health and therapeutic problem in both the developing and developed countries. It has significantly increased during the last two decades (El-Helaly, Kamel, Abd-Elaziz, Elwan & Nabih, 2009; Alsayed, Gad & Azab, 2007). According to Alsayed et al. (2007), obesity subjects individuals to metabolic and endocrine disorders. Such complications can pose significant risks to children’s health and general life performance. Additionally, it can lead to an increase in many complications and illnesses which further results in obstruction of a country’s economic progress and the development of an entire health care system (Parikh, Edelman, Uwaifo, Freedman, Semega-Janneh, Reynolds, & Yanovski, 2004; Wang & Dietz, 2002; Afridi, Khattak, Safdar & Khan, 2003). In conclusion, overweight children are at risk of vitamin D deficiency and secondary hyperthyroidism. It is clear that BMI may be a significant risk factor for vitamin D deficiency obese and non-obese children and adolescents. Considering the above cases, it is recommended that obese children, especially those with high body mass index, take routinely vitamin D supplementary treatment. Additionally, they should go for routine screening with regard to vitamin D

A9 - Assignment Example They further suggest that the purpose of affirmative action is not to create reverse discrimination (Cosson, 2010). Affirmative action is now embraced by businesses in their hiring strategies and models. While it brings with it some disadvantages such as reverse discrimination, it also has a wide range of advantages. These include; diversity in the work place, increased moral commitment by companies and increased opportunities for minority groups. Therefore, the benefits that stream from affirmative action exceed the disadvantages. In the case between the male candidate and the agency, the agency was right in reaching its decision of hiring the female candidate. This is because the agency, in making its decision, embraced the fact that besides from creating increased opportunities for women who are qualified, diversity in the work place was also fostered. Diversity enables organizations to draw more insight from different employees especially in problem solving. In the above case, tw o major issues emerge. Firstly, affirmative action remains controversial and divisive. Secondly, it creates a whole range of merits and demerits. It is controversial and divisive because it tends to favor certain groups of persons such as women, and at the same time appear discriminative against others. Its advantages are increased opportunities for minority groups such as Hispanics, diversity in the work place, and an increased moral obligation to society by businesses (Cosson, 2010). However, on the other hand, affirmative action policies create room for stigmatization and reverse discrimination The main challenge with affirmative action is visibly the issue of discrimination. While affirmative action policies drum support for equality and diversity in the work place, the issue of discrimination remains unresolved. The writer clearly shows that the male candidate was obviously discriminated against in the form of gender, all in the name affirmative action. Discrimination

Student visas problem Essay Example for Free

Student visas problem Essay Abstract American by no means is the world’s superpower. The country is very advanced in many aspects like education, technology, business and Research with prestigious learning institutions like the renowned Harvard University. For these reasons student across the globe strive to come to the US and get their education from here. In most cases the various graduates of the American colleges and Universities always stand a higher chance of getting employment into their careers. Graduates from the American educational system are highly regarded as extremely qualified and can also be integrated by employers anywhere in the world. (http://www. hothousemedia. com) Unfortunately most foreign students who come to the US on student Visas end up not pursuing education but take advantage of the various loopholes to remain in the country illegally. With the increased issue about terrorism, most terrorist have taken advantage of the student visas to gain entry into the American Soil where they pursue their own terrorist activities that endanger the lives of the Americans: for example one of the terrorist involved with the 9/11 attack is said to have been a student on such a Visa. For this particular reason the authorities in American have tightened the rules and regulations that govern the acquisition of these Visas. To acquire a student visa today is extremely difficult than before and many aspiring students are denied the opportunity to study in the US because of these restrictions. However, from the American point of view it is justifiable because the security of the country comes first before anything else. (www. unitedstatesvisas. gov). The students on the other hand are not able to understand these issues, and more or less view it as one of the hindrance of them acquiring the much sought after American Education. To acquire the student visas the American immigration department has comprehensively undertaken the task of educating the â€Å"would-be American students† of the requirements for one to acquire the visas. Unfortunately the students do not sometimes understand the requirements thus fail in acquiring these important items. The students may not also know the laws governing the student visas; the immigration rules in the US are rated as some of the strictest and specific, thereby shutting out many aspiring students. Introduction Millions of foreign students are always fighting to get a place in the American academic institutions. The quality of education in the US is highly regarded across the globe which assures anyone a very promising career development. Prior to the September 11 attack, the acquisition of the American student visa was not as difficult as it is today, which has become a nightmare not only for students but businessmen and women including tourists. (http://www. businessweek. com) Most of the challenges that the students face come from the lack of clear understanding of the rules and regulations surrounding the visas. However, the regulations that govern the visa application are extremely punitive and innocent students are left out. This paper is going to discuss some of the difficulties faced by these students. The application process The first major challenge the students face in acquiring the Visa are the various rules and regulations that one has to understand before applying. Students are required to pay a non-refundable fee of $131, which does not necessarily guarantee one of getting the Visa in the first place. This fee is very prohibitive because not so many students can be able to afford it especially bearing in mind it is never refunded if the visa application is not successful. (http://www. businessweek. com) Part of the Visa application process involves an interview with the US Embassy or consulate where further screening is done on the students to ascertain the authenticity of their application. To secure the interview posses greater challenges, this is because depending on the months that one is applying, one is bound to get appointments that might jeopardize the scheduled dates of joining the university or college. It requires the students to start making the applications very early because the appointments can be as far as one month depending on the applications made. Even after acquiring the appointment the students go through various screening processes that maybe dehumanizing especially to the innocent students. Such screening processes include frisking, and finger printing, besides the interview itself. Many students fail to acquire the visa because they fail on various technicalities that they were not clearly made aware of. Sometimes it is extremely difficult to clearly understand the criteria used to award visas, in fact most of the time one considers him/herself lucky to pass the interview. Thus it is not what one has but the mood of the interviewer that matters. There are many cases where students with almost similar backgrounds have varied outcomes on the application; while one may get the other may miss out. The student is never given the opportunity to lobby for a consideration as the word of the interviewer is regarded as final. Therefore the visa application process is always shrouded in mystery, where there are no clear guidelines on who gets the visa or who doesn’t. Therefore one is not really sure that they will pass or fail. Many students after failing the rigorous tests become very discouraged and they are affected psychologically because of the high expectations they had. (Mashiur Rahaman) One of the best solutions for this problem is to educate the students on the visa application process; thereby the students are fully aware of the various pitfalls that they need to overcome and every single detail that is required for the visa process to be successful. To secure an appointment for an interview in a particular embassy is not necessarily a difficult task because all this can be done on-line. However the embassies get busy in July through August and most students may miss out because of the schedules that are fixed by the embassies. ( http://www. bridgeport. edu ) The students who fail in these interviews end up losing the $131 fee and to secure another interview they require a similar amount. This is a very big challenge and the fee should be refundable or just a part of it so that the students can secure other appointments. Students from poor families end up losing their lively-hoods yet they don’t acquire the much-sought document. The U. S embassies should have clear and specific guidelines on the criteria used which should never be shrouded in any form of mystery where a student can out rightly tell if they are qualified or not. (http://www. cnsnews.com). Another challenge that the students undergo in the visa application process, is the requirement that they should provide proof that they will not go to the U. S for other purposes and that they are capable of supporting themselves when they get there. The students or guidance are required to show proof of there bank accounts which are supposed to hold a certain amount of money for a period of time. Many instances students are able to finance there own education by working part time. In any case this requirement means that only the rich stand the chance of getting the American education. Because of the many restrictions students end up cheating in their documents and providing incorrect information. ( http://www. bridgeport. edu ) Once a student has successfully acquired the visa, another problem sets in; one needs to pay for the visa. The amounts are very prohibitive bearing in mind that one needs to pay for the education, airfare, accommodation, and other important materials. Therefore by the time one settles down in the U. S, if you are lucky enough you are poorer than you came in. (http://www. cnsnews. com) Once in the U.S, to ever get the opportunity to go back home to be with your family is almost next to impossible. This is because the chances of ever being accommodated back are very slim. There are many cases of students being delayed for up to 1 year when they want to come back for what is termed as security screening. Students from the Muslim world have to go through harrowing experiences for them to ever go back to the U. S after their holidays. (http://www. cnsnews. com) It is often advisable to stick in the U. S for as long as you are in college unless you want to waste time and money with the immigration. One should forget for a long while of ever going back home for up to 4 years. Students with tight family ties end up suffering a lot. (http://www. cnsnews. com) Conclusion The terrorism issue has gone a long way in making it harder for innocent students to pursue their dreams in the U. S. It is quite understandable of the strict rules that the visa application processes attract, because any loophole would be greatly exploited by the terrorists who do not discriminate in there harmful activities. Students have to bear the brunt of terrorism. It also important for the students to be fully aware of the visa requirements before starting the process, this will enable them avoid any eventual disappointment.

Tumorigenic effectsYes, in nude mice CommentsCells are weakly positive for keratins Culture Method The base medium for this cell line is formulated RPMI-1640 Medium. 6.2.1 Tryphan Blue dye Exclusion Assay Method75 Table 5: List of instruments Table 6: List of Chemicals Experimental Design The designed study consists of three groups viz: Negitive control, Control, Test. In the Negative control group the cell lines were incubated with the medium for a period of 24 hours. This group was designed to rule out the possibility of any growth inhibitory effect of certain compounds of medium. The control group was designed to rule out the effect of any residual or traces of solvent with which the extract was prepared on the growth inhibition of cell lines. Here the solvent employed was ethanol and hence it is added at the concentration of 0.1% (v/v) in distilled water. In test group different concentrations of test extract i.e, 10, 25, 50, 75 and 100 µg/ml are incubated with colo 320 cell lines for a period of 24 hours. This group was used to study the effect on cell line viability. Table7: Experimental Design to Study the Effect of Ethanolic Extract of Corallocarpus epigaeus L on colo 320 Cell Line Viability by Tryphan Blue Assay Procedure 1. An aliquot of cell suspension being tested for viability was centrifuged for 5 min andsupernatant was discarded. The size of the aliquot depends on the approximate number of cells present. The aliquot is taken such that it contained a convenient number of cells to count in a haemocytometer when suspended in 1 ml PBS and then diluted again by mixing with 0.4% Tryphan blue (e.g., 5 Ãâ€"105 cells/ml). 2. The cell pellet was resuspended in 1 ml PBS or serum free complete medium. Serum proteins stain with Tryphan blue and can produce misleading results. Hence determinations must be made in serum-free solution. 3. Mix 1 part of 0.4% Tryphan blue and 1 part cell suspension (dilution of cells) cells were mixed and allowed to incubate at room temperature for approximately 3 minutes, Cells were counted within 3 to 5 min of mixing with Tryphan blue, as longer incubation periods will lead to cell death and reduced viability counts. Mixing was performed in a well of a microtiter plate or a small plastic tube using 10 to20  µl each of cell suspension and Tryphan blue. 4. A drop of the Tryphan blue/cell mixture was applied on to haemocytometer. The haemocytometer on the stage of a binocular microscope and cells were focused clearly. 5. The no. of unstained (viable) and stained (nonviable) cells were counted separately in the haemocytometer. Seeding of Cells COLO 320 cells were cultured to reach the 80-90% confluency using RPMI 1640 medium. After reaching the desired confluency, culture was collected and centrifuged at 3000 rpm for 10 minutes to get cell pellet. The pellet was resuspended in 1ml of fresh culture media. Cell concentration was determined by Tryphan blue assay was performed by mixing 50  µlitres of culture and 50  µlitres of 0.4% tryphan blue dye. Finally cells seeded in 24 well plates at the concentration 10000 cells/ml and incubated at 5% co2 incubator at 370 c for 24 hours. Drug Treatment Cells were maintained in 24 well plates in triplicate for every concentration, and treated with different concentrations of (10, 25, 50, 75, 100 µgm). Corallocarpus epigaeus L, test compound and control groups were treated with medium and ethanol. The treated cells were incubated for 24 hours in 5% co2 incubator at 370c. Invitro Cytotoxic Assay After 24 hours incubation the cells were collected from each well in eppendroffs and centrifuged at 3000rpm for 10 min to get cell pellet, to the pellet 50 µlit of each medium and tryphan blue was added and mixed well to suspend the pellet. Cytotoxicity was screened by performing tryphan blue assay. Percent of growth inhibition was calculated by using the following formula 6.2.2 Micro Culture Tetrazolium Assay76 Plant Material Used: Whole plant ethanolic extract of Corallocarpus epigaeus L.

Figure 13: Reduction of MTT to a formazan compound by mitochondrial Enzymes Cell Lines Human colorectal adenocarcinoma- colo 320were obtained by sugen Life Sciences Pvt. Ltd., Tirupati from an authenticated supplier. Stock culture of these cell lines were cultured in RPMI -1640 with 10% inactivated newborn bovine serum, Penicillin (100 IU/ml), Streptomycin (100 µg/ml)) under humidified. The cells were dissociated in 0.2% trypsin and 0.02% EDTA in phosphate buffered saline solution. The stock culture was grown in 25cm 2 tissue culture flasks and cytotoxicity experiments were carried out in 96 well microtiter plates. Procedure Cell lines in the exponential growth phase were selected, washed, trypsinized and suspended in complete culture media i.e, RPMI 1640. The microtiter plates and incubated for 24hrs during which a partial monolayer was formed. They were then exposed to various concentrations of the extract (1-100 µg/ml). Control wells received only the maintenance medium. The plates were incubated at 37 °C and 48 hrs and cells were periodically checked for granularity, shrinkage and swelling. After 48 hrs, the sample solution in wells was flicked off and 50 µl of MTT dye was added to each well. The plates were gently shaken and incubated for 4 hrs at 370C in 5%CO2 incubator. The supernatant was removed and 50  µl of DMSO was added. The plates were gently shaken to solubilise the formed formazan. The absorbance was measured at 540nm. The percentage of growth inhibition was calculated using the following formula, Values of absorbance were converted into percentage of residual viability. Usually the Inhibition concentration 50% (IC50) is chosen as the best biological marker of cytotoxicity. The IC50 value represents the concentration of the test extracts that reduced 50% of cell inhibition. Statistical analysis Statistical evaluation of data was done by one-way analysis of variance (ANOVA) followed by Tukey’s multiple comparison test on viability using computer based fitting program (Prism graph pad prism version 6.03) statistical significance was set at p,0.05. IC50 was calculated by linear interpolation method using the formula IC50 = Ãâ€"(D-C)+C Where A = The first point on the curve, expressed in percent inhibition, that is less than 50% B = The first point on the curve, expressed in percent inhibition, that is greater than or equal to 50% C = The concentration of inhibitor that gives A% inhibition D = The concentration of inhibitor that gives B % inhibition

Salaries in Professional Sports Back in 1965 if you were playing professional baseball for the richest team in the league you would be earning approximately 35 000$ a year, being the case you’re a standout type player, a â€Å"franchise player† as there also referred to. Thirty-five years later, if you were to hand 35 000$ to a super star, they would turn and laugh. For in today’s game, 35 000$ would not even come close to covering the signing bonus. Somehow over the last thirty-five years or so professional sports has turned from a loveable pastime into a greedy business. The majority of players play no longer for the love of the game; they play only to fatten their wallets. Players in professional sports have somehow lost what brought them to play the game that they loved so much as little children, passion! Players in today’s modern era have traded their passion for glory. Back in the early day of pro sports players would work hard day in day out just to earn enough to support there family, and even then, many athletes had to work outside of there sport just to earn enough money. So you knew that those man played not for the glory nor for the money but for the love of the game. But today, well sadly you really have to wonder sometimes. Can you really say that a man who would turn down 150 million to play pro ball just because he feels he can make 200 million is playing for the right reasons? So now your really only left with one question, what can we do about it? Well you know what, as bad as it is, the problem could be fixed in the blink of an eye. The reason the problem is so simple to fix is because players, even though they might think they do, have absolutely no control what so ever. All the power lies in the hands of the owners. If the owners would decide enough is enough, you would never ever hear about an athlete signing a contract worth 250 million dollars again. You see what truthfully separates the men from the boys in pro sports teams, is talent, and the team with the most talent will win. And the only way to get talent is by handing over the big dollars to the most talented players. That’s why teams like the New York Yankees, and the Detroit Red Wings, and the Los Angeles Lackers rise above the rest, there owners are willing to hand out more of the big bucks to players in order to assure a winning team.

Donald Davidsons What Metaphors Mean Essay -- Writing Literary Essays

Donald Davidson's What Metaphors Mean Our literal understandings of a word are twins in constant opposition with one another, twins in constant competition to receive the most love from their mother and father. Let us pretend the parents are the literary community that demonstrates love frequently by showing a preference for one of their twins. Donald Davidson's theory expressed in What Metaphors Mean is a tragic, intellectual miscarriage; it is a theory of language that brings forth a stillborn child, a dead metaphor. Do you see the candle there in the window? What does it mean to you, and is your understanding of its "ordinary" essence, its literal meaning, identical to mine? Davidson assumes we both clearly know and agree upon its literal meaning, that it is literally "a cylindrical mass of tallow or wax with a wick through its center, which gives light when burned." Contrarily, however, I believe our understandings of a simple word like candle often file for divorce because they cannot resist the semantic temptation of what I metaphorically call literal-meaning infidelity. Metaphorical meaning is a sex object for literal meaning, and the mind of a creative artist, a lover of humanities and poetry, is incapable of not pursing this with passion unleashed via creative language-libido. This kind of person has a mind fundamentally opposed to the Davidsonesque mind, a mind that is constantly discovering (if he reads a book of prose or poetry) and inventing (if he writes with a pen in his hand) the me taphorical connection with lust filled eyes. The above literal, dictionary definition of candle is not the first definition that enters my mind, I am afraid, and thus how can there only exist a literal "surface" meaning inside... ...rn to a state of mind that only acknowledges objective, literal meanings in words, denying language its natural tendency of allowing meanings to evolve and expand. It is imperative for us, especially all poets and writers of prose that use language to express figurative meaning, to critique this theory because it only decreases creativity and denies that artist say anything beyond the literal with their words and metaphors. Davidson's ideas violently affront to the purpose of our craft. If we become completely dependent upon objective, literal meaning and learn to reject subjective, figurative meaning in words, we will consequently become less human and more detached from the world, from our natural surroundings, from our fellow human beings, and from the spontaneous, creative voices deep in our guts that often speak of truths literal expression cannot capture.

Defects of Human Nature Essay

Human nature can be defined as being the psychological characteristics of humankind which are understood to be shared by all human beings. In the novel â€Å"Lord of the Flies† by William Golding, the flaws of human nature are explored in detail. When critics asked Golding about the theme of the novel, he replied, â€Å"The theme is an attempt to trace the defects of society back to the defects of human nature† (p. 204). He believes that political systems cannot govern society effectively without first taking into consideration the defects of human nature. One of the numerous flaws in human nature which is illustrated in â€Å"Lord of the Flies† is the reluctance of admitting one’s mistakes. The characters in this novel are of young age, the oldest being around 12 or 13 years old. This leaves room for many mistakes to be made, as young children are bound to make mistakes. It is human nature to deny mistakes, and to instead blame mishaps on others. In the beginning of â€Å"Lord of the Flies†, when the first meeting is held, Piggy suggests a head count to keep track of everyone, especially the â€Å"littluns. † Ralph and Jack dismiss this idea by making fun of Piggy instead of taking his comment into consideration. There was a little child that talked about a â€Å"snake-thing† (p. 35). He is only distinguished by a mark on his face. The other boys laugh at the child and write off the idea as a nightmare. Later, when the boys are looking for wood, they come across a snake-pit. It is then when Piggy realizes that the small boy with the mark on his face is gone. â€Å"That little’un that had a mark on his face–where is–he now? I tell you I don’t see him–where is he now? † (p. 46-47) Piggy reprimands the other boys for not listening him and taking a head count. Instead of admitting his mistake, Ralph shamefully mumbles an excuse: â€Å"Perhaps he went back to the, the–† (p. 47). Ralph and Jack also blame the incident on Piggy who was put in charge of the â€Å"names. † However, it is not Piggy’s fault because there was no way that he could accomplish this task without the cooperation of the other boys, which was not available to him. The absence of the little one is ignored and is never spoken of again. This is an example of how people are reluctant to admit their mistakes and would rather blame things on others. When Simon realizes that the beastie is not real, but is rather the dead parachuter, he feels obligated to inform the other boys of his discovery. However, Simon barges in on them during one of their feast celebrations. The boys at the feast are dancing and are caught up in the excitement of the night. Not fully aware of the situation, when Simon made his unannounced entrance, he was mistaken for being the beast. In the excitement of the night, nobody realized the mistake and as a consequence, Simon was brutally murdered. After the incident, nobody believed that they actually committed the murder, and instead they all try to find excuses for their actions: â€Å"‘Don’t you understand, Piggy? The things we did–‘ ‘He may still be–‘ ‘No. ‘ ‘P’raps he was only pretending–‘† (p. 157). â€Å"It was an accident, that’s what it was†¦ coming in the dark. He was batty. He asked for it. It was an accident†¦. It was an accident, and that’s that. † (p. 157). Ralph and Piggy are not comfortable with what they had done when they woke up the next morning. Ralph realizes what happened, but Piggy persistently attempts to find an excuse for their actions, as can be seen in the quotes above. He denies all involvement in the murder and struggles to prove to himself, as well as to Ralph, that they both were not connected to the killing in any way. Sam and Eric [or Samneric] feel the same way about the situation as do Ralph and Piggy. The twins act as if they were not present when the murder took place, even though it is obvious they were. They justify this excuse by pretending that they left the feast early because they were â€Å"tired. † Piggy and Ralph go along with this explanation and actually use it for themselves as well: â€Å"‘We left early,’ said Piggy quickly, ‘because we were tired. ‘ ‘So did we–‘† (p. 158). All four of the boys are pretending that they do not know of what is going on and are shaken by the â€Å"dance they had not attended† (p. 158). Throughout â€Å"The Lord of the Flies†, William Golding identifies many â€Å"defects of human nature. † One of the themes of the novel is an â€Å"attempt to trace the defects of society back to the defects of human nature† (p. 204). The flaws in human nature must be taken into consideration in order to build a successful political structure. In this novel, the young children do now have this knowledge and therefore their society breaks down. It is in human nature for one to be unwilling to admit one’s mistakes, and throughout the Lord of the Flies, Golding has exemplified this flaw in a variety of different ways.

The Importance of Extracurricular Activities Camry

â€Å"The Importance of Extracurricular Activities† Academics are an important part of every student's high school years. This is because academics play a big role in college acceptance. Students are encouraged by teachers and/or parents everyday to study. Every parent want their child to attend college but only want to pay less; that's one reason why they encourage their child to study more. However, there is one more other thing students can do other than academic relations I. E. Extracurricular activities. Extracurricular activities include basketball, baseball, tennis, student government, drama, choir and there things.Besides being fun and socializing with peers, extracurricular activities can enhance their time management skills. Extracurricular activities increase your chances in getting accepted for colleges. When students are involved in activities, they learn how to work in groups. Their communication skills improve. These things cross over to real life. College admis sion committees want to see students doing more than just book work. The privilege to even play on a team comes with certain requirements. Students may have to meet and maintain a minimum grade point average to play any ports or be in any clubs.Some extracurricular activities are made to help at risk teenagers. They begin to have an increased sense of self-worth, and it increases their' health. They develop life-long relationships with their peers and learn how to lead others. These activities help you stand out from the crowd. Getting involved in too many activities can have negative effects. Students involved in too many activities usually end up having academic problems. Students should pick out their favorite activities and make sure they can handle them.They shouldn't try to do it all even though it shows their passion ND commitment to activities, which builds character. These activities that students are involved in reveals a lot more about them. To put it briefly, students wh o participate in extracurricular activities will see an improvement in their academic and life skills. They will be disciplined, gain goal-setting skills, accountability and responsibility. They will also be better prepared for college. Students may even distinguish the lessons they learned outside the classroom. Extracurricular activities will help them survive in the future workplace.

Janissaries and Chinese Eunuchs

Eunuchs and Janissaries In the ancient world, both the east and the west , they had their special system. It depended on the culture of these countries and what they used to. For example, in ancient Chinese, the court was full of maids, princess, concubines and the queen. But there were plenty of works which was too dirty or too hard for maids to do. They needed men. Not only the high-blooded was super Important, but also they might Influence the power if they colluded with each others. The emperor certainly could not stand them. So he made a decision that castrating the eunuchs. Term hundreds of years, there were a good deal of eunuchs that tried to rebel, tried to rob or steal the power. Eventually emperor forbid eunuchs to ask anything about politics. It did work. Janissaries was also the salary group which worked for emperor. However, It recruited the children from 7 to 10 years old by devilries. They must be trained for more than 10 years and then they fight as the strongest and honesties army Instead of doing dirty and heavy work In court. The reason why they are the honesties people was not only the ten-year train but also the agreeable reward.It seems that every officers, provincial governors even the vizier, one of the powerful jobs chose their generation from Janissaries. Such a considerable bonus was great enough to make Janissaries do their best for their lord. However, the ages from 7 to 20 are supposed to be the most wonderful memory for each person. Disclaimers broke them and take back a bloody battleground. I can not stand it. Although eunuchs can not have fun with their dream lover, but that was their choices. They wanted to get a life without poor . Those were what they paid for. Janissaries can choose nothing. It was unfair. It was not humanistic.

12 Angry Men †Critical Thinkers Essay

In Twelve Angry Men, a young man is on trial for stabbing and killing his father. The movie focuses on twelve randomly selected citizens who are assigned the duty of determining the fate of this 19 year old man. The jury is supposed to examine certain facts and determine the truth based solely on the evidence presented to them in court. It is assumed that the jurors will judge fairly and without personal bias. Basically, the jurors need to use critical thinking during this trial to figure out what evidence is factual and what evidence is false. Throughout the film, some jurors were better at critical thinking than others, some had obstacles to overcome before they could use good critical thinking skills, and yet others became critical thinkers at different points during the movie. Critical thinking played a key role in Twelve Angry Men. In order to be able to think outside the box, one must possess the ability to think unbiaslly, not bring personal issues into play, not be scared to put the ideas and doubts on the table, and to be level headed. The juror who possessed these skills the best and applied them better than his eleven other companions was juror number 8, played by Henry Fonda. At the beginning of the movie, juror 8 was the only one to vote not guilty on the first vote. Fonda’s character plainly stated â€Å"It’s not easy for me to raise my hand and send a boy to die without talking about it first†. This shows that he wanted to examine all the evidence and â€Å"facts† before coming to his decision. As the movie went on, juror 8 kept posing questions like â€Å"could it be possible† and â€Å"could he be wrong† to remind others that about reasonable doubt. Then Fonda’s character helped find holes in two key pieces of evidence, one being the knife used in the murder. The switchblade knife was supposed to one of a kind, but juror 8 takes a knife out of his pocket and jams it into the table next to the knife that was used in the murder. The knives were identical and Fo nda’s character explains that he bought it in the same neighborhood. The second piece of evidence juror 8 found reasonable doubt in was the old man’s testimony. The old claims he heard the killer yell ‘I’ m gonna kill you’, a second later he heard the father’s body fall and he saw the boy running out of the house fifteen seconds after. Juror 8 decided to reenact the scene, paying attention to detail my dragging his foot like the old man, as well as, measuring the distance so that it was accurate. Fonda’s character proved the old man’s story was false because it took thirty-one seconds. Juror 8 payed attention to details, analyzed every detail, put aside his biases, and opened the eyes of the other jurors, this is why he was a great critical thinker. Although there were some good critical thinkers in Twelve Angry Men, there were a few jurors who just couldn’t see outside the box until it was almost too late. Juror 10 seemed to be the most close minded of all his peers, resulting in bad critical thinking. There were instances where this character stereotyped the defendant racially by saying â€Å"those people†,†them†, â€Å"they are born liars† and â€Å"they do not value human life†. Juror 10 also referred to calling the boy ignorant and a slob. This juror not only treated the defendant poorly, but his behavior towards his companions was ignorant. Juror 10 was sarcastic, insensitive, lacking morals, holding grudges, and a l oud mouth. For instance, juror 10 sarcastically says â€Å"you’re a smart fellow aren’t you?† to juror 8 in response to a piece of evidence that had been shredded. All of these characteristics are ones that cloud the mind and do not allow common sense or critical thinking to come into play. There were three individuals that held so much grudhe, anger and aggression that it prevented them from thinking critically. One of these peers was juror 3. He claimed that the defendant was certainly guilty and his reasons for thinking this was completely prejudice. He brought thoughts of anger, resentment and revenge into the jury because his own son left him. For this he thinks and blames all young folks. Another jury who was a bad critical thinker is number 2. He tends to follow the crowd and feels like its an open and closed case. He doesn’t want to see the facts as they are nor does he want to listen to what anyone says. The last juror who bad at thinking critically was 6. Though he gave juror 8 a chance, the reason was because he was too narrow headed to figure out the evidence wase. He couldn’t connect any of the dots nor did he speak up very much in the discussion. Twelve Angry Men had good examples of how the average person uses critical thinking, which is while the process of conversion is occurring? For some reason the light bulb dings on after we listen to others explain their th oughts. Jurors 9, 11 and 7 were like most of us. During the trial juror 9 kept voting guilty until Fonda’s character started talking about the old man’s character and the woman’s eyesight. He voted not guilty after he thought about the old man’s character being alone, never had recognition in life for anything, and he wanted some so the old man lied. Juror 9 had to overcome his own perception of himself being old and not really needed for much in order to be a critical thinker and realize his opinions count too. Like juror 9, juror 7 had to overcome his preoccupation of going to a Yankee’s game. Throughout the film, he kept voting guilty and then after he heard jurors 8 and 10 talk about how the woman wore glasses and she didn’t have them on when she saw the murder. When this happened, juror 7 realized that there was reasonable doubt in the case. This only happens after he voted not guilty just to get to the ball game and Fonda’s character asks him why, which then makes 7 pay attention and think. Juror 11 was an immigrant who was scared and easily swayed by his peers. He had the obstacle of trying to stand up for himself, understand his voice counts and that his mind works just like others. Juror 11 conquered this obstacle when juror 8 was talking about the wound, he realized that the someone taller would have had to been the killer. He also explained to the others that a switchblade is use in an upward motion. Once these characters got over their obstacles, their critical thinking skills helped open holes in the case. All in all, Twelve Angry Men was a great learning tool to what critical thinking is and how to apply. This film taught me that you have to approach decisions in a certain manner. I need to keep an open mind, be level-headed, express my opinions and not judge others. Thinking critically implies that brain power of yours and your peers is needed to get a better understanding of everyday life. Respecting others around you is key. In order to use critical thinking, one must know what it entails.

The History of Concrete and Cement

The History of Concrete and Cement Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance known as an aggregate (usually made from different types of sand and gravel), that is bonded together by cement and water. Aggregates can include sand, crushed stone, gravel, slag, ashes, burned shale, and burned clay. Fine aggregate (fine refers to the size of the aggregate particulates) is used in making concrete slabs and smooth surfaces. Coarse aggregate is used for massive structures or sections of cement. Cement has been around a lot longer than the building material we recognize as concrete. Cement in Antiquity Cement is thought to be older than humanity itself, having formed naturally 12 million years ago, when burnt limestone reacted with oil shale. Concrete dates back to at least 6500 BCE when the Nabatea of what we know now as Syria and Jordan used a precursor of modern-day concrete to build structures that survive to this day. The Assyrians and Babylonians used clay as the bonding substance or cement. The Egyptians used lime and gypsum cement. The Nabateau are thought to have invented an early form of hydraulic concrete- which hardens when exposed to water- using lime. The adoption of concrete as a building material transformed architecture throughout the Roman Empire, making possible structures and designs that could not have been built using just the stone that had been a staple of early Roman architecture. Suddenly, arches and aesthetically ambitious architecture became much easier to build. The Romans used concrete to build still-standing landmarks such as the Baths, the Colosseum, and the Pantheon. The arrival of the Dark Ages, however, saw such artistic ambition dwindle alongside scientific progress. In fact, the Dark Ages saw many developed techniques for making and using concrete lost. Concrete would not take its next serious steps forward until long after the Dark Ages had passed. The Age of Enlightenment In 1756, the British engineer John Smeaton made the first modern concrete (hydraulic cement) by adding pebbles as a coarse aggregate and mixing powered brick into the cement. Smeaton developed his new formula for concrete in order to build the third Eddystone Lighthouse, but his innovation drove a huge surge in the use of concrete in modern structures. In 1824, the English inventor Joseph Aspdin invented Portland Cement, which has remained the dominant form of cement used in concrete production. Aspdin created the first true artificial cement by burning ground limestone and clay together. The burning process changed the chemical properties of the materials and allowed Aspdin to create a stronger cement than plain crushed limestone would produce. The Industrial Revolution Concrete took a historic step forward with the inclusion of ​embedded metal (usually steel) to form what’s now called reinforced concrete or ferroconcrete. Reinforced concrete was invented in 1849 by Joseph Monier, who received a patent in 1867. Monier was a Parisian gardener who made garden pots and tubs of concrete reinforced with an iron mesh. Reinforced concrete combines the tensile or bendable strength of metal and the compressional strength of concrete to withstand heavy loads. Monier exhibited his invention at the Paris Exposition of 1867. Besides his pots and tubs, Monier promoted reinforced concrete for use in railway ties, pipes, floors, and arches. Its uses also ended up including the first concrete-reinforced bridge and massive structures such as the Hoover and Grand Coulee dams.

The Role of The Natural World essays

The Role of The Natural World essays A long time ago, one kind of wise creature called human being appeared in the natural world. After many years, in todays world, that creature became the dominator of the world. While they were getting more and more intelligent, an ambition came out. Human beings wanted to conquer the whole natural world. However they havent succeeded yet. The role of the natural world in human society hasnt changed. It is both as a friend and an enemy to human society. As a friend to human society, the natural world gives life to humans and also supplies necessary resources to them. People need food to survive. The natural world offers them vegetables, fruits, and meat to eat. People need clothes to keep warm. The natural world supplies them cotton and feathers to make clothes. People need shelter to live. The natural world provides them stone and wood to build houses. People need conveyances to travel. The natural world gives them animals to take them to where they want to go. With the improvement of technology, natures role in satisfying the basic needs such as food, clothes, shelter and conveyances cant satisfy human beings any more. However, humanitys friend, the natural world, creates lots of entertainment for humans. For those people who like traveling, they can enjoy thousands of amazing views in the natural world. For those people who like swimming, they can find lots of rivers, lakes and seas. For those people who like skiing, they can go to some snow-capped mountains. For those people who like skating, the natural world even freezes lakes for them. The natural world satisfies both human needs and wants; it is an ideal friend. On the other hand, the natural world also brings human disasters; it is a terrible enemy. A common trouble in human society is flood. If there is a heavy rain in some places for a long time, it will cause rivers water level to increase, and to flood the villages or farms...

Evolution of Container Shipping essays

Evolution of Container Shipping essays This report will provide information about containers and the shipment of containers in the past and present. It will tell how the idea of shipping goods in containers came about and how those ideas have progressed into what is now known as the container fleet of today. It will explain what the first containers were like and what the containers of this modern industry are like now. It will also look into the future of shipping with containers. This report shall completely inform and even interest the layman person in the modernization of container shipping. Firstly is to explain exactly what containers are. They are large boxes that actually come in a few sizes, but they all have a similar rectangular shape. The most common sizes of todays containers are 8 feet wide, 8 feet high and either 20 feet or 40 feet long. Others may be 24 feet, 28 feet, 44 feet or 48 feet long and there are, in addition, many other sizes than those. Despite all of their different sizes, one thing they do all have in common is how they are measured. They are all measured in TEUs. TEU stands for Twentyfoot Equivalent Unit. It is a measurement of the containers volume. One very important aspect about these large boxes is that they need to be made strong. This is so they can withstand rough weather at sea aboard a ship while stacked on top of one another. The bottom container in some stacks needs to support up to ten containers while on land as well. They need to be able to last for about 8 to 20 years, so they are generally made out of steel or aluminum. Since th ese containers spend much of their time at sea and are always outdoors, they need to be waterproof. These are a few physical attributes that help explain what containers may look like. There a few different types of containers, but they all meet the dimensions and requirements mentioned in the above paragraph. The first and most common is the metal box container with just a layer of dunn...

A Brief History of the Invention of Plastics

A Brief History of the Invention of Plastics The first man-made plastic was created by Alexander Parkes who publicly demonstrated it at the 1862 Great International Exhibition in London. The material, called Parkesine, was an organic material derived from cellulose that once heated could be molded and retained its shape when cooled. Celluloid Celluloid is derived from cellulose and alcoholized camphor. John Wesley Hyatt invented celluloid as a substitute for the ivory in billiard balls in 1868. He first tried using  a natural substance called collodion  after spilling a bottle of it and discovering that the material dried into a tough and flexible film. However, the material was not strong enough to be used as a billiard ball, not until the addition of camphor, a derivative of the laurel tree. The new celluloid could now be molded with heat and pressure into a durable shape. Besides billiard balls, celluloid became famous as the first flexible photographic film used for still photography and motion pictures. Hyatt created celluloid in a strip format for movie film. By 1900, movie film was an exploding market for celluloid. Formaldehyde Resins - Bakelite After cellulose nitrate, formaldehyde was the next product to advance the technology of plastic. Around 1897, efforts to manufacture white chalkboards led to casein plastics (milk protein mixed with formaldehyde) Galalith and Erinoid are two early tradename examples. In 1899, Arthur Smith received British Patent 16,275, for phenol-formaldehyde resins for use as an ebonite substitute in electrical insulation, the first patent for processing a formaldehyde resin. However, in 1907, Leo Hendrik Baekeland improved phenol-formaldehyde reaction techniques and invented the first fully synthetic resin to become commercially successful with the trade name Bakelite. Here is a brief timeline of the evolution of plastics.

Significance of the Copernican Principle

Significance of the Copernican Principle The Copernican principle (in its classical form) is the principle that the Earth does not rest in a privileged or special physical position in the universe. Specifically, it derives from the claim of Nicolaus Copernicus that the Earth was not stationary, when he proposed the heliocentric model of the solar system. This had such significant implications that Copernicus himself delayed publishing the results until the end of his life, out of fear of the sort of religious backlash suffered by Galileo Galilei. Significance of the Copernican Principle This may not sound like a particularly important principle, but its actually vital to the history of science, because it represents a fundamental philosophical change in how intellectuals dealt with humanitys role in the universe ... at least in scientific terms. What this basically means is that in science, you shouldnt assume that humans have a fundamentally privileged position within the universe. For example, in astronomy this generally means that all large regions of the universe should be pretty much identical to each others. (Obviously, there are some local differences, but these are just statistical variations, not fundamental differences in what the universe is like in those different places.) However, this principle has been expanded over the years into other areas. Biology has adopted a similar viewpoint, now recognizing that the physical processes which control (and formed) humanity must be basically identical to those that are at work in all other known lifeforms. This gradual transformation of the Copernican principle is well presented in this quote from The Grand Design by Stephen Hawking Leonard Mlodinow: Nicolaus Copernicus heliocentric model of the solar system is acknowledged as the first convincing scientific demonstration that we humans are not the focal point of the cosmos.... We now realize that Copernicus result is but one of a series of nested demotions overthrowing long-held assumptions regarding humanitys special status: were not located at the center of the solar system, were not located at the center of the galaxy, were not located at the center of the universe, were not even made of the dark ingredients constituting the vast majority of the universes mass. Such cosmic downgrading [...] exemplifies what scientists now call the Copernican principle: in the grand scheme of things, everything we know points toward human beings not occupying a privileged position. Copernican Principle versus Anthropic Principle In recent years, a new way of thinking has begun to question the central role of the Copernican principle. This approach, known as the anthropic principle, suggests that maybe we shouldnt be so hasty to demote ourselves. According to it, we should take into account the fact that we exist and that the laws of nature in our universe (or our portion of the universe, at least) have to be consistent with our own existence. At its core, this isnt fundamentally at odds with the Copernican principle. The anthropic principle, as generally interpreted, is more about a selection effect based on the fact that we do happen to exist, rather than a statement about our fundamental significance to the universe. (For that, see the participatory anthropic principle, or PAP.) The degree to which the anthropic principle is useful or necessary in physics is a hotly debated topic, particularly as it relates to the notion of a supposed fine-tuning problem within the physical parameters of the universe.

Biography of Sigmund Freud Essay Example | Topics and Well Written Essays - 1250 words

Biography of Sigmund Freud - Essay Example Freud’s father was a merchant and had a textile business in Freiberg. This business had supported Jacob and his wife Amelia till the birth of Sigmund. However, the business started to fall when baby Sigmund was just four years. Prejudice against the Jews had increased in Austria. However, legal restrictions against them had loosened. In other words, the Jewish doctors, academics, businessmen, and lawyers were gaining important positions in the society of Austria. In fact, the failure of Jacob Freud’s business together with the loosened restrictions was the main reasons why the family moved to Leipzig in the year 1859. They then moved to Vienna, Austria in the year 1860 where they lived in Leopold Stadt which was an area of the Jews (Hergenhahn, 2009).Young Freud was already an uncle at the time of birth. This is because his father had two other sons from a different marriage which existed before he met Amalie Freud. The two half-brothers were Emmanuel and Philip. John, one of his half-brother’s son, was young Freud’s favorite playmate when they were living in Freiberg. Amalie gave birth to another son called Julius one and a half years after Sigmund was born. Studies show that Sigmund was very jealous of Julius. This jealousness perhaps prompted Sigmund to develop sibling rivalry theory later in his career.Sigmund and his siblings were brought up with a non-religious background despite the fact that his parents had been raised as followers of the Orthodox Jews.

His marriage to a Christian is clear from his treatise tended to my wife. His appointment as a minister is less sure in spite of the fact that Jerome alluded to him as a center of life and presbyter of the congregation. Tertullian arranged himself as a layperson. Tertullian was the most productive Latin journalist until Augustine and formed works that are contrite, polemical, and moral in nature. After years of guarding universal Christianity, in any case, he turned to Montanism, a Spirit-based development, which Tertullian called the New Prophecy and which underscored prescience, elate articulations and glossolalia, women in service, thorough profound quality, and eschatological desires. As stated by Augustine, Tertullian withdrew from the Montanists to establish his own particular gathering of Tertullianists, making yet an alternate break. The year and way of his demise are obscure, yet Jerome reported that he existed to a progressed age. Late grant has called into address much of what Jerome reported about Tertullian. Timothy David Barnes, specifically, destroyed Jeromes life history of Tertullian and reproduced a short anecdotal representation built exclusively with respect to Tertullians own particular revelations. According to Barnes, Tertullians surviving works secured a concise period from 196 to 212, permitting a conception date as late as 170 (Ward, pp. 137-139). The explanations for Tertullians acknowledgement of Montanism remain a puzzle tohistorians. He offered no subtle elements in his surviving compositions, despite the fact that his lost treatise On Ecstasy potentially held such information. Jerome proposed that Tertullian was determined to Montanism by clash with Roman church. The trickiness of Jeromes confirmation that Tertullian was a

Foundation Law Assignment Example | Topics and Well Written Essays - 1500 words

Foundation Law - Assignment Example The compensation claimed in major cases are a) road accidents b) accidents at work place c) accidents due to ill equipped / ill planned safety and security measures d) gadget deficient to meet accident eventualities e) accidents at home f) accidents during holidays. In order to broaden the base of personal injury, we may include medical and dental injuries under the purview of personal injury. The chronic diseases found in the work force at industrial work places are termed as industrial diseases2. In case of non-responsible attitude of one party towards another party, if proved, is a ripe case to claim monetary compensation from the party at fault through the competent court of law. In western countries claim of compensation that relates to personal injury is a complex issue. Usually the solicitor charge in terms of percentage according to the volume of compensation claim at the end of the case provided it is awarded. Since the compensation under medical malpractices is rampant in t he western countries, therefore it is necessary for a claimant to engage a counsel of repute to plead his or her case in a competent court of law3. In the given scenario, Matthew, who is the warehouse operator is the claimant while the defendant is the pharmaceutical company, which has to follow certain employment rules and regulations under employment law. English employment law is applicable here as it is the employer’s responsibility to handle situations related to the employees at the workplaces. The English law does not provide an indefinite period of time to the claimant of compensation under personal injury. In the English territorial jurisdiction, an individual can claim compensation within a period of three years from the date of its occurrence. Therefore, under the law in vogue, court proceedings should be commenced within the given time limit. Otherwise the claimant might lose the opportunity to seek relief from the court of competent jurisdiction. The only excepti on is that if a person met with an accident under the age of 18 years, he or she may have the opportunity to claim compensation before the maturity of 21 years through court proceedings. The court has the discretion to waive the time limit if convinced. Another remedy available to ignorant person is that if he or she comes to know that he or she may claim compensation of personal injury under the law. In that situation claimant may file compensation within a period of three years which starts from when he or she comes to know that they are entitled for compensation under personal injury4. The key element is determining the veracity of negligence of the coworker that caused compensation to the claimant. No doubt that the claimant has suffered in both ways a) physically and b) economically. Therefore, both losses (disability of Mathew to perform duty / inability to pay off liabilities) are to be taken into consideration while deciding the case of compensation. It was held by the compe tent court of law in the case of Lunney and Oliphant (2008) that law of tort merits restoration of victim to its original physical status prior to the incident. It is the court to decide the amount of compensation keeping in mind the level of damages that occurred due to incident / accident. In the case of Overseas Tankship (UK) Ltd v Morts Dock and Engineering Co Ltd, it was held that the defendant can be liable for foreseeable consequences. Further,

Psychology Laboratory Report Essay Example | Topics and Well Written Essays - 1500 words

Psychology Laboratory Report - Essay Example Perceptions of body image are of research concern for psychopathologies such as anorexia nervosa and bulimia, amongst both women and men (Fallon & Rozin, 2985). Body-image can be defined as a person's self-concept of their physical appearance (Strickland, 2004). Investigation of the sociocultural differences between genders in body image perception is increasing (Fallon & Rozin, 2985). Fallon and Rozin (1985) report that women tend to weigh themselves more often, are more likely to consider themselves as fat, are more likely to be on a diet, and tend to seek medical assistance with weight issues more frequently, as compared to men. These results, state Fallon and Rozin, may be related to women on average being less satisfied with their appearance than men. Further, studies appear to indicate body image perception in general for women and men is focused on issues of weight (Fallon & Rozin, 1985). Fallon and Rozin cite a study by Gray in 1977 that found women were more likely to consid er themselves overweight as compared to objective measurements, whereas men were likely to perceive themselves as underweight. Gray concluded that across the genders participants misperceived their weight when compared to their own gender, and make judgments about their weight based on standards that do not incorporate the health model (Fallon & Rozin, 1985). An example of such a standard is the perceptions of the ideal body image as judged by the opposite gender (Fallon & Rozin, 1985).Later research supports conclusions that many people experience a discrepancy between their perceptions of an ideal body image and their actual body image (Byrne & Hills, 1996). Sociocultural influences on perceptions of body image may be attributed to media portrayals of the ideal body within a western industrial nation (Fallon & Rozin, 1985). Traditionally targeted at the female form, media portrayals of a body ideal now extend to both women and men (Yang, Gray & Pope, 2005). Fallon and Rozin (1985) found that on average men tended to rate their current, ideal and attractive body-image as very similar. Whereas, women's ideal image tended to weigh less, than both current and attractive ratings. Fallon and Rozin highlighted in their results that perceptions of what the opposite sex consider an ideal body-image are usually wrong. They found that women considered men to desire a slimmer female form as compared to what men reported they liked, and men perceived women to be attracted to a heavier male form than what women reported.Studies have investigated methods to quantify the difference between an individual's perception of ideal and actual body image as a measure of body-image disturbance (Byrne & Hill, 1996). Importantly, it is necessary that such instruments be standardized for the populations they are used for, for example females and males, or differences in age or ethnicity (Byrne & hill, 1996). The Stunkard Body Shape Figure Scale (Stunkard et al., 1980 as cited in Strick land, 2004) is one such scale. The patterns of ranking perceived ideal and actual body image have provided insight into how females or males as a group differ amongst themselves, as well as in

Supply chain management Operations management Lean production Essay

Supply chain management Operations management Lean production - Essay Example Thousands of the Model-S were preordered which was more than the company expected. It was also an indication that the market was ready for electric cars (Carlson, 2012). Tesla also makes electric powertrain parts which it then sells to other automakers such as Toyota and Daimler. The company is headed by Elon Musk who envisions it as an independent an independent automaker in the future with the aim of mass-producing fully electric cars of all types at affordable prices for average customers. The company is named after Nikola Tesla, who was an electrical engineer and physicist. In fact, the AC motor fitted in the Tesla Roadster is based on an original design by Tesla in 1882. The Roadster was the first electric vehicle powered by lithium-Ion batteries to have a mileage of greater than 200 miles per charge. And made news for achieving a lot of what other vehicles such as the Toyota Prius could achieve. This gave the company a favorable platform to begin from; one where the attention h as been captured in the market (Carlson, 2012). Definition and Application of Operations Management The operations management at Tesla are streamlined for success, which is particularly attributable to the CEO’s experience in nurturing success. ... There are however a knowledgeable board of directors made up of open thinkers such as Antonio J. Gracias and Steve Jurvetson (Carlson, 2012). In the course of production, different managers lead different departments that undertake individual operations. For instance, the batteries are one of the most important parts of the vehicles made by Tesla and are hence overseen by a manager with expertise in the production of batteries. The board of director made up of the key figures in the organization oversees the general operations of the company while specialized managers take hold of exclusive operations such as painting, body work, interior and so forth. This ensures that operations are well overseen, and hence adhere to the preset goals (Chase, Jacobs, Aquilano, 2007). One aspect to the company that captured the interest of the market is the way its â€Å"much publicized† organization operates. With the release of an electric sports car that actually fit that title, the pubic w as interested to know how it all takes place behind the headlines. The plant where the vehicles are put together is located at Fremont, California. The way operations in the plant are designed has a profound impact on whether its objectives are accomplished, and this is one of the fortes Tesla holds. As illustrated above, different departments operate and are overseen by individual experts. The plant is laid out in a way that the inputs come in from one side and leave as finished vehicles in the other. The basis of this design is most likely to harbor what each and every organization desires; efficiency. The skeletons of the soon to be vehicles follow a sequence that is well

Criminal justice Assignment Example | Topics and Well Written Essays - 500 words

Criminal justice - Assignment Example Of course, there is a general societal consensus that certain things are wrong and should be discouraged or criminalized, but for proponents of the Nanny State, the government should seize control of actions and issues where there is no consensus and unilaterally impose its view of morality on these issues. Why is this happening more and more these days? Many experts believe that in an increasingly complex world people are more willing to turn over power to the government in order to make their own lives easier. There is a sense the world can be and should be completely ordered and that government is the right body to do this. This is an unfortunate state of affairs as it tips the important balance between liberty and order far to the side of order. There are so many examples of this way of thinking that it is hard to know where to begin. One of the most shocking examples from recent years is the following headline: â€Å"Chicago Prohibits Foie Gras.† In 2006, Chicago city council voted to ban the delicious appetizer foie gras from the city’s restaurants. Proponents of the ban said the production of foie gras was inhumane. Opponents had a different view. "Government shouldnt be dictating what we eat," said the chef at one French restaurant. The Mayor too was unhappy. "We have children getting killed by gang leaders and dope dealers," he said. "We have real issues here in this city. And were dealing with foie gras? Lets get some priorities."1 These opponents are right. In an era where people expect to be coddled and protected from everything that could possibly harm, they are allowing things as personal as menu choice to be dictated by the government. If an individual does not like to eat foie gras no one will forc e them to eat it; but the Chicago city council went a step further by eliminating this choice completely and limiting the rights of those who do like foie gras. The Nanny State continues to expand, rolling
