King Asok Not More Than A Myth Essay - 1530 Words

For a long time, King Asoka was thought to be nothing more than a myth. With several writings concerning him, they all relayed too fantastical an image to be convincing as truthful, keeping him in a legendary status. This all changed in 1837, well over a thousand years after his death, when a scholar James Prinsep managed to translate writings on a stone pillar in Delhi. After several other scholars raced to translate similar writings all over the Indian landscape, it was revealed that this King Piyadasi was the same as King Asoka. Even with his history pieced together, Asoka’s history is still legendary. He started as a lowly person shunned by his own father and grew to be a ruler of a kingdom that had never seen complete unity. But indeed, despite the face of caring compassion he attempted to convey to the Indian people, and despite the reforms he made to various sectors of his kingdom, it is clear Asoka was only using Buddhism as a way to unite the people and, more importa ntly, keep them under his control. It is rumored that Asoka’s grandmother was a Greek princess, with his lineage being traced back to the Seleucus kingship, and that his Asoka’s grandmother would have told him stories of Alexander the Great and other Greek warriors, inspiring Asoka and gearing him towards being the warrior he would become in the Kalinga Wars. Asoka’s mother is supposed to be the daughter of a Brahman, a Hindu priest. She eventually married the King of India, one of the first of theShow MoreRelatedFundamentals of Hrm263904 Words   |  1056 Pageswith the most effective instructor and student resources With WileyPLUS: Students achieve concept mastery in a rich, structured environment that’s available 24/7 Instructors personalize and manage their course more effectively with assessment, assignments, grade tracking, and more manage time better study smarter save money From multiple study paths, to self-assessment, to a wealth of interactive visual and audio resources, WileyPLUS gives you everything you need to personalize the teaching

The Civil Rights Movement - 1204 Words

Victims Frustration In general, historians will have us believe that the fight for Civil Rights was one fought in the South. While this is predominately so, there were still people to the North and West that needed representation during this struggle. The situation in the South mainly revolved around the reluctance of local authorities to follow the national legislature after the Brown v. Board of Education of Topeka decision. Black Power became synonymous with urban riots in Harlem, Detroit, and Watts. Author Brian Behnken argues that putting a geographical face on each sub-movement creates difficulty when trying to understand the movement as a whole. Instead of focusing on the difference in the areas where struggles were occurring, it is important to concentrate on why. What brings nonviolence and Black Power together regardless of location is the mere fact that those participating in each were victims of racism. Some of the more common examples of cruelty during the Civil R ights Movement include the Birmingham Campaign which was met with tear gas, police dogs, and water hoses being used against the protestors and the Selma to Montgomery March which resulted in police-inflicted beatings. In each, the participants were engaging in non-violent protest when officials reacted with force. While these two instances occurred in Southern areas, the injustice in police brutality was witnessed in other areas as well.

Business Research Process Enhancing Risk Research

Question: Discuss about the Business Research Process for Enhancing Risk Research. Answer: Introduction Surveys are the primary sources of any research process. For the purpose to conduct research every research needs an instrument to fulfill its needs and requirements. Instrument is a tool which helps in enhancing research work and its validity. This article talks about a standout amongst the most inconsequential parts of a researcher's day by day assignments, which is to choose among different accessible choices the instruments to perform information gathering that meet the planned destinations and, in the meantime, regard budgetary and temporal confinements and in addition other similarly important issues when directing an exploration. The instrument for information accumulation is a key component of the customary polls, which are utilized to examine different themes of enthusiasm among members of logical studies (Mesa, DA, JL, RR; 2014). It is assumed by the researcher that the validity is available in the instrument that will be reflected when it is going to used in research process (Paulo, 1999).An exploration can be judged both as far as interior Validity when its decisions are right for that specimen of concentrated on people, and additionally outside Validity, when its outcomes can be summed up to different settings and populace domains (Koogan; 2002). Moreover, to be substantial in any measurement this examination ought to have utilized a set up instrument, ready to recognize people who really have this dermatological condition from the individuals who don't have it. In this way, the study's Validity examine relies on upon the Validity of the very instruments that are utilized. An examination instrument is regarded dependable when it can reliably create similar comes about subsequent to being connected over and again to similar gathering of subjects. This idea is regularly utilized as a part of different phases of the examination procedure including, quality control check. Reapplying a few inquiries to similar subjects as of now met or notwithstanding amid the development of another instrument in the test-retest stage in which the Reliability quality and consistency of the given answers are analyzed (ISAAC, 2006). A study or a research will get more strong and validated if more instruments are used in analyzing the things. The intrigued peruser ought to counsel particular productions for further examination of this topic (SAGE, 1979) Continuing our unique question, it must be noticed that the requirement for cautious determination of instruments to be utilized as a part of logical examinations must have a strong hypothetical premise and ought not be considered as a unimportant prevailing fashion. Wrong selections of the instrument can downward the research process. Creating misdirecting comes about, which are in this manner not able to answer the examination address initially figured (university press, 2006). Plus, the decision of an instrument likewise has suggestions in the capacity to sum up the exploration comes about (outside Validity), and to contrast them and those of different studies led broadly or globally on similar subject - specialists utilizing identical instruments can build up a powerful exchange, which empowers a more thorough investigation of the wonder being referred to, including its predecessors and consequences (JW, 2007) Lets take an example of the Job Satisfaction Survey. The instrument is made out of 36 Likert scale things. On account of this specific instrument, you can compute an aggregate score, or you figure nine sub-scale scores. In the event that you need to think about general occupation fulfillment, the aggregate score would be an adequate measure (koogan, 2012). It is essential while selecting a study instrument that it has been observed to be dependable and substantial. Reliability quality alludes to the degree that the instrument yields similar results over different trials. Validity alludes to the degree that the instrument measures what it was intended to quantify. There are a few approaches to evaluate the dependability and Validity of the instrument once information has been gathered be that as it may, these components are essential to know before information accumulation. To figure out whether the instrument has been demonstrated solid and legitimate, it is critical to examine the instrument and discover what past studies learned ("Survey Selection and Administration - Statistics Solutions", 2016). A fast appraisal of past research that utilized the instrument ought to permit you. While selecting an overview instrument, it is critical to know how add up to scores or midpoints are ascertained and what higher or bring down scores demonstrate. Periodically, in study instruments, the device can be included contrarily worded things and additionally emphatically worded things. At the point when scoring these instruments, it is imperative to know which things should be switch scored before computation. It is vital to see how the instrument has been scored in past studies and to copy that scoring strategy for your study. One other element to consider while selecting an instrument is the kind of information you will be acquire. On the off chance that you are wanting to utilize a just illustrative study, the outline of the reaction alternatives can fluctuate from question to address. On the off chance that you plan to utilize inferential measurements, it is useful to have the capacity to make add up to scores. Keeping in mind the end goal to make add up to scores or normal scores, you regularly need all reaction choices that make up a specific scale or sub-scale to have similar range, maybe 1 - 5 where 1 = firmly differ and 5 = emphatically concur. Keep in mind, the two most vital calculates selecting an instrument are that the instrument measures your variable of intrigue and that it is solid and legitimate. That data combined with alternate recommendations will help you in the choice of a fantastic instrument. There are various factors which need to be considered when selecting instrument for survey: Instrument should be well-tested factorial structure, validity reliability Supportive material should be available for further research and for analysis purpose. Normative data should be available in order to analyse, interpret and validating data. Instrument should be applicable to whole selected population. User friendly Availability Financial cost Amount of time required Conduct a pilot survey in order to test the validity rather than being use it at a first shot for whole selected population. After that the instrument should be selected that can meet the objectives of the study, considering budget, moral and time requirements, among others. In an examination setting at whatever point altogether the picked instrument has been made unmistakable from that of research, scan the writing for investigations of diverse adjustment that expected to create a proportionate variant of the instrument, exploration context (MF, CL, 2007). Thus, as contended by Reichenheim and Moares, "the procedure of multifaceted adjustment ought to be a mix between a part of exacting interpretation of words and expressions starting with one dialect then onto the next and a fastidious tuning process, that addresses the social setting and way of life of the objective populace to which the rendition will be applied."10 Check the Validity and Reliability quality of tests and instruments. Do they truly quantify what they claim to gauge? Do they quantify reliably over the long haul, with various research subjects and ethnic gatherings, and after rehashed utilize? Examine articles that utilized the test will frequently incorporate Reliability quality and Validity information. There might be some issues in selecting instruments: There might be some issues while selecting instrument of survey, it is a numerous choice while setting research (Community Tool Box, 2016). There are various options available for the research, the decision is to be taken in the manner that which instrument suits the research purpose (Socialresearchmethods.net, 2016). Population Issues Is the population literate? Can the population be enumerated? Will the population selected for research purpose corporate? Do we need to face language issues? What are the following geographic restrictions? Sampling Issues Is the relevant data available? Will we be able to find respondents? Who will be the respondents? Are response rates likely to be a problem? Question Issues Types of questions which can be asked? Should questions be complex or simple? Open or close ended? Can questions be lengthy?

The Elegant Universe. Superstrings, hidden dimensions and the Quest for the Ultimate Theory Review Paper Essay on The Elegant Universe. Superstrings, hidden dimensions and the Quest for the Ultimate Theory Regarding the advanced science, I note only that the bullet that kills, not whistles and, of course, on the contrary: if the whistles, then already past. Apparently, so is the case with distortion. The thing is that under the action of gravity is curved, apparently not the space itself, and, above all, the trajectories of elementary particles. Speaking of popularization should not forget that under it often mimics a type of huge flow of-the-art intelligent fool , widely represented in the pseudo-scientific environment. Infamous popularizers with claims of another loud coup are available in each of the areas of knowledge. Physics is not an exception.

Designed with this quite certain the aim of science is trying in good faith to answer the questions put to it. The results of these efforts are the most discouraging: the result of long efforts very often it turns out that the answer to these questions can not be given that the issues properly raised that a correct statement of the problem is of enormous difficulties and demands of labor, significantly surpassing the one that seemed at first to be sufficient to fully address the problem. Further brings a new surprise: it turns out that science and not an instrument to answer as soon as one or the other problem is getting a final decision, it falls outside the scope of science in the area postnauchnogo knowledge So, the task of science. the correct formulation of the question. But to determine which of the question is correct and what is not, is impossible without a study of the motion of methods from ignorance to knowledge, without determining whether the issue lead to the answer in principle. Therefore, the whole range of methodological issues everything that is connected with the path from question to answer (but not with the answer) belongs to science. Awareness of science to its specificity and its waiver on those activities for which it has no means, is a huge step on the path of knowledge. However, this step is often disappointing in preverzhentsev .zdravogo sense. in science, which is beginning to seem too distracted occupation. Naive realism comes to science as a pagan with his idol: first, he prays to him, believing that he is able to help him overcome all the difficulties, and then, disappointed, sechot him and thrown into the fire or into the river. Turning away from science, he is trying to enter into a direct bypassing it alliance with the world postnauchnyh productive knowledge with the world answers when we are witnessing a craze popular literature, books that should not acquaint the reader with the progress of science and its methods, and results and s olutions before us typical cases Union pre- and postnauchnyh stages of knowledge against science. However, this alliance has no future: the answers given by science, they can not be separated from it the most. They are not absolute and lose value when nominated their methodology is replaced by a new one. One should not think, however, that a marked contradiction between pre-scientific, scientific and postnauchnym stages of knowledge an irreconcilable antagonism. Each of these points needs to rest. In particular, science not only draws the raw material from the sphere of everyday experience, but also needs a correlation controlling its movement with the world .zdravogo sense.

buy custom My Closest Friends essay

buy custom My Closest Friends essay I have several closest friends, and Mike and Adam are among them. I have known them since my childhood and I think that I am lucky because they are very good friends. I respect both of them and I believe that their traits and beliefs will help them to succeed in their lives. Though Mike and Adam have a number of differences, there are certain similarities that predetermine their friendship. One of the main differences between Mike and Adam is that Mike is an extravert while Adam is an introvert. Mike adores going out and communicating with various people. By contrast, Adam prefers staying at home. Sometimes it is almost improbable to lure him out of his apartment. He says that he is exhausted after a long working day, or that he just would like to relax and watch a movie. Such preference makes Adam not good at socializing. He often has difficulties in communicating with people he meets for the first time in his life, while Mike can find a common topic with everyone. These two individuals have different attitudes towards the Internet. Taking into account Adams love for staying in his room, he spends much time in the Internet. He is interested in playing video games, reading blogs and news. Video games take up a lot of his free time. Adam compensates the lack of communication in the real life with the help of social networks and virtual reality. He spends so much time online that some neighbors think that he has moved out several years ago as they almost do not see him. For Mike, the Internet is a means, but not a solution. He uses it only when he needs to buy or find out something. Although Mike likes video games, too, he does not play often. Another distinction between them is their attitude towards sport. As most of the introverts, Adam is rather passive and, therefore, rather indifferent to any sporting activities. Although Mike does not go in for sports now, he is open to plaing amateur football from time to time. When Mike was a child, he used to practise acrobatics. He was very good at this sport, but then he got hurt during one of the trainings. After the trauma, there were several more incidents. Finally, he gave up this activity. Mike and Adams occupations also differ. Both of them are not afraid of physical labor. Mike works as a shop assistant and Adam is a builder. However, Adams occupation is temporary because he would love to have a white-collar job, while Mike loves his work being good at selling. Adams dream is to become a web designer one day. While staying at home, Adam manages to distract from video games and devote time to practicing web design. Before reaching his main goal, he wants to try working as a program tester. Their levels of intelligence also vary. Luckily, both of the men have copious vocabulary: it is very interesting to communicate with them, and their jokes are rather rich. Nevertheless, Adam is more intelligent than Mike. He is fond or reading. He also spends much time searching for pieces of news concerning everything: technology, innovations, politics, economy, and research. He also loves sharing this news with his mates which makes him very valuable as a friend. Although Mike likes learning new things too, his knowledge is not so profound. Mike knows a little of everything enough not to seem shallow during the conversation. The two friends understand the sense of life differently. Adam considers constant development to be the most significant thing in his life. He cannot live without learning, analyzing, reflecting, and sharing his views about the world. Mike is a more earthling person. He admits that money is the most valuable thing in his life. His purpose is to earn, not to learn. In any case, it would be wrong to judge both views. It is clear that if everyone were a daydreamer, then the state of the global economy would be rather poor. Of course, if these two individuals had nothing in common, it would be weird that they are friends. For example, both of them care for their homes. They love feeling comfortable when they come home. Thus, both of them decorated their apartments the way they liked. They chose and planned everything: furniture, the color of walls, floor, and even the design of all home appliances. This process was rather exciting for both of them. Neither Mike, nor Adam let their girlfriends decide anything concerning remodeling. Both friends are very ambitious and do not lose any opportunity of being their own bosses. For example, Mike used to sell special gloves that were fit for smartphones. He managed to find a relatively new field that did not require much investment. Adam has found a way to earn on reselling jewelry made of silver. He purchases pieces from a silversmith at a low cost and then finds buyers. The two men are very stubborn. They got used to getting what they want. If they decide to reach something, they always succeed in it. It is possible to observe this trait if to discuss their higher education. Mikes parents are rather rich but he left the college after two years of studying. Soon he proved that he was able to provide for himself without any help of his parents. Adams family did not want him to start working so early, but he did it because he wanted to pay for his tuition on his own. Finally, both of them are kind and they are ready to help and protect their close ones. It is impossible for any of them to refuse to give a hand when one of their relatives or friends asked for it. Moreover, sometimes there is no necessity in asking they just help. To conclude, Mike and Adam do not have many things in common. Nevertheless, their similarities are more significant than differences. Different hobbies or attitudes towards something are not as important as readiness to help and striving to live a better life.

Are the Millenium Development Goals achievable Essay

Are the Millenium Development Goals achievable - Essay Example However, as years passed, it was increasingly apparent that these goals would not be realized. Today, the declaration is already halfway through its timetable and this paper will discuss why the MDG will be a failure by the year 2015. One of the main targets of the Millennium Development Goals is the eradication of at least 50% of the world’s poverty. This has been one of the most problematic areas in realizing the objectives due to its financial implications. Adrian Bradbrook (2005), for instance, argued that in order for about 1 billion people to live beyond the $1 dollar a day benchmark, they would need to have access to modern energy services, as this is an important precondition for the eradication of poverty. (224) The magnitude of this dilemma is staggering. Bradbrook stated that a cumulative investment of US$200 to $400 billion dollars ($40 billion per year) for people to access energy services such as electricity, liquid and gaseous fuels, electrical appliances for cooking and so on. This challenge is highlighted by the decline in finances of international agencies and the failure of respective governments to generate funds themselves in order to address basic energy needs due to fiscal difficulti es. This is besides other factors that require large scale funding such as the installation of infrastructures and technologies that will spur development in poor countries. Here, we encounter another dilemma in addressing the issue on international partnership on development. One should remember that overseas development assistance extended by developed countries are generally conditional, and in the realist view, are driven by self-interest. That is why the institutionalization of welfare principles in this front, which is central to the MDG’s success, has been nothing but rhetoric.

Poverty and Pollution - Assignment Example Keywords: pollution, poverty, businesses, third world country, operations, control, regulation, morality, environment, standards, global, enforcement Poverty and Pollution There are many different moral and ethical considerations that must be addressed when looking at the issue of the pollution of third world countries by businesses who have setup shop in those countries, including but not limited to the implications of the companies who are participating in these actions, the reasons for doing what they are doing, the moral right of human beings to a livable environment, as well as who should be responsible for these actions, and what must be done to improve the quality of life of those who are affected by these practices. There are many different reasons a business may conduct operations in a third world country, including political instability, a need for investment capital, low wages are acceptable, as are low benefits, education levels are low, and environmental regulations are few and not seriously enforced (Encyclopedia of Business 2nd Ed, 2013). Political instability in a developing country ensures that both the powers running the country and those who are attempting to run for the company are both concerned with public image; they want to ensure that the people see that they are attempting to better the country, even if the decisions made do not actually benefit the country, and one key aspect of this is good PR. If the ruling power or the power attempting to be the ruling power shows any indication that they are driving away big businesses, businesses who will bring new jobs to the country, which will in turn strengthen the economy, even if that businesses practices ultimately hurt the country itself, they will be seen as working against the country itself, and not for the country, even if baring that particular business from the country will ensure a higher quality of drinking water in the country, for example. The key is to show a form of immediate gratification for the people in terms of a better economy, even if the environmental concerns are far more severe. The need of the country for investment capital also factors into the decision of the third world country to open its doors to big business. Many big businesses will, for example, work to better the country that they choose to setup shop in, as a means of being able to more efficiently conduct their business. In Mongolia, for example, as a result of the search for rare earth mineral deposits, many big companies are working to build access roads, supporting local businesses and patronizing shipping systems setup in place in the country; Germany signed an agreement with Kazakhstan to be able to gain access to their rare earth minerals in exchange for technical assistance in modernizing railroads, building chemical plants, and other forms of development (Caramenico, 2012). It is because of the desire for technological advancements that the big businesses are able to provide that countries are more likely to overlook the negative aspects of big business in favor of the investment capital that they will provide. Businesses like the arrangement because they are able to get cheap employment, both in terms of the wages that they pay out and

Behaviour Management in the Classroom Essay Example for Free

Behaviour Management in the Classroom Essay Knowing how to anticipate and manage problems will ensure that students spend maximum time on task, and those students who are eager to learn are not disadvantaged by a few. I have found there are many different causes of disruptive and inappropriate behavior. These can include factors in and out of a teacher’s control. Factors outside the control of the teacher may include a student’s emotional and psychological factors. A student may have significant distressing issues in their home life such as bereavement or family breakdown for example. Students may also have had negative past experiences at a previous establishment or in the education system in general. Some students may behave inappropriately through boredom or finishing work to quickly, while others misbehave in an attempt to mask undiagnosed learning differences. Conversely, I have experienced students being disruptive in class due to having a special educational need, students with undedicated Attention Deficit Hyperactivity Disorder for example. ‘Some teachers think a well-planned, interesting lesson will by itself prevent disruption. Or that if the teacher is entirely benign and respectful of students, conflict will simply melt away. This isn’t the case. ’ (Petty, 2006, pg3) The teacher themselves can sometimes be a cause of negative behaviour. Some students may act up through boredom as a result of a teacher being unprepared, demotivated or simply not giving enough consideration to lesson design. Bad classroom management can also be a factor, for example, allowing students to play with mobile phones or simply poor seating arrangements, which allow disruptive students to sit together. Review organisational policies relevant to managing behaviour in the learning environment identifying any areas for improvement | Every teaching establishment will have a number of different organizational policies relating to managing behaviour. Appendix A lists the specific policies I have to adhere to in my organisation. The policies are very diverse ranging from a staff code of conduct with pupils, to policies rela ting to effective teaching and learning. The specialist nature of my establishment means there are many policies linked to the welfare and safeguarding of students, including a number of anti-bullying policies (including anti-cyber bullying) to procedures relating to pastoral care. In my opinion, the behavior management policy in my establishment could be improved. There is no consistent approach to managing behavior throughout the organization. It is left to individual teaching staff to use their discretion as to what constitutes disruptive behavior and how to deal with it accordingly. Although the senior managers are usually supportive of teaching staff, It would be beneficial to staff and students for there to be a set procedure we could all follow. |Review ways of encouraging behaviours that contribute to an effective learning environment | |Use strategies for encouraging behaviours that contribute to an effective learning environment | ‘†¦classrooms become much more orderly when rules are stated, or better still negotiated, discussed and fully justified. It seems the little lighters need persuading of the obvious! ’ (Petty, 2006, pg3) There are many strategies to help a teacher limit disruptive behavior during lessons. I find an effective tool for managing behaviour is to set firm ground rules at the beginning of the course. These include clear boundaries, and expectations. If this can be done in consultation with the students it can be extremely effective, as it gives them the responsibility of managing each other’s behavior. It is use ful to note however, that set sanctions must also be clearly defined and followed as a consequence for breaking the rules for this technique to be effective. The use of reward is a good method of encouraging positive behavior, the use of praise, certificates and house points for example. ‘What we can’t do however is ignore disruptive behaviour. If we do, it won’t go away! ’ (LSDA, 2007, pg8) It is important for a teacher to challenge disruptive behaviour immediately and consistently. I feel by trying to make lessons enjoyable and providing work that helps students to achieve minimizes disruptive behaviour. The use of good communication by the teacher can also be a useful tool. This includes the use of the voice, phrasing, eye contact and body language. For example, using an assertive tone when making a request or physically positioning yourself near disruptive students. ‘You should be alert, businesslike, firm and unapologetic. But you must avoid showing anger or frustration even when you feel it. ’ (Petty, 2006, pg19) I feel getting to know students individually and knowing what their interests and expectations are helps. I find by creating a working relationship where students feel valued and respected is key to minimizing inappropriate behavior. In my opinion, the greater amount of respect the pupil has for you, the less likely they will misbehave. I agree with Petty (2006) when he states: ‘prevention the best strategy’ It is also important should a student misbehave that it is dealt with swiftly with the teachers focus being placed on the student’s behaviour, rather than the individual themselves. |Review ways of managing behaviours that disrupt an effective learning environment | No matter how hard you work at perfecting your behaviour management techniques, you will encounter ‘the really challenging-class’ at some point in your career’ (TES,2010) If a situation arises where an individual’s behavior is persistently disruptive, further action may be required to ensure the other students maintain an effective learning environment. The use of graduated sanctions in schools and colleges is a widely recognised, and is a commonly used method of controlling individuals that have not responded to other behavior management strategies. Having the support of heads of departments and senior management teams is crucial for this method to work effectively. I have, on occasion had to follow behaviour management procedures at my organisation that use graduated sanctions. For example, referring disruptive individuals to my head of department. If that student then continues to affect the learning of others they get referred to a member of the senior management team (SMT). The last stage being the Head Master, who has the power to take more serious action if required, such as temporary and permanent exclusions. Summarise own strengths and development needs in relation to managing behaviours that disrupt the learning environment | In general, I feel that managing my student’s behavior is one of my strengths. It is something I have learned, and improved upon through the years in my current teaching position. I have learnt different strategies for minimizing disruptive behaviour through observing other staff in my depar tment, and openly discussing individual cases with other teaching staff. With regards to my personal development, I would like to attend some training to help me manage students with disruptive behavioural disorders, specifically, Oppositional Defiant Disorder. Although I currently teach two individuals diagnosed with this disorder, they can be extremely disruptive in a group environment, and I believe attending training specifically related to managing this type of psychiatric disorder would be extremely beneficial for the future.

our town :: essays research papers

Our Town   Ã‚  Ã‚  Ã‚  Ã‚  Our Town, by Thornton Wilder is a play that takes place in a small fictional town of Grover's Corner, New Hampshire; beginning in 1901 and ending in 1913. The play takes the audience through the cycles of life, with the purpose of getting a message across stating that life shouldn't be taken for granted. Emily Webb, one of the most important characters in the play, is Wilder's character in which he uses to show the audience a message that anyone would understand and relate to.   Ã‚  Ã‚  Ã‚  Ã‚  Emily is a character that is normal enough so that the audience could relate to her; and be different in little ways that makes people love and admire her. These cycles makes her common, thus relatable to the audience. Without going through common events in life, the character would seem distant and likeable to the audience. Similarly, when Emily said that she expects a man to be perfect, it makes her special. Wilder put in that scene because he believed that even though there is a basic image of an average person, to be truly average, the character must have a difference to separate the character from the crowd. If the character doesn't have any differences, then the character would be faceless; impossible for the character to take a major role in the play. Emily is portrayed uniquely in her own way, and yet is still within the boundaries of everyone else.   Ã‚  Ã‚  Ã‚  Ã‚  The character Emily plays a crucial scene in the play, the part where Emily went back to her twelfth birthday. At first, Emily wanted to go back and relive the happiest day of her life, but Mrs. Gibbs stopped her and told her to visit a normal day instead. Mrs. Gibbs knew what would happen to Emily if she had relived a joyful day in her life. If Emily had went back to a special occasion, she would've been overwhelmed by the all the beauty that she didn't pay attention to. Therefore, Emily went to relive her twelfth birthday, but wasn't as happy as she thought she would have been.

The ambiguity in “My Papa’s Waltz”

Theodore Roethk’s â€Å"My Papa’s Waltz† is a poetry of the twentieth century. When discussed, the poem instigates again and again some very interesting and conflicting opinions. Often examination of this brief and seemingly accessible poem inspires animated debates on the possibility of messages of child abuse and alcoholism. â€Å"My Papa’s Waltz†, recounts the treasured childhood memories of the poet. The structure of the poem, the iambic trimetric quatrains has the rhythmic romp of the waltz. The poem should be read within the context of its time frame.This poem was authored in 1948, an era when readers would not have shared the same emotional response about these issues that are displayed by contemporary readers. The meaning of many phrases and words in the poem can be misinterpreted as an indication of child abuse. A close reading and analysis of the poem help us avoid such misconstruction. According to Karl Malkoff, Roethke had a deep almost religious respect for his father, Otto Roethke. He had admiration for his father’s ability and fear for his strength. Otto Roethke owned greenhouses and worked in them as well.Roethke saw his father with his labor helped the flowers grow. His love combined with his awe-inspired dependency that a son has for his father can be clearly seen in the poem. The poem consists of four iambic trimetric quatrains. The rhythmic style and the rime patter of the quatrains (‘breath’, ‘death’ and ‘easy’, ‘dizzy’,) make us feel the rhythm of the waltz. It shows the good time the boy is having with his father. As the readers of the last decade of 20th century, we are very much aware of the issues of child abuse and alcoholism.We are conditioned to think even the slightest hints of abuse and alcoholism as glaring sigs of problems. These subjects were not heard at the time when it was written. Moreover his use of the word ‘papa’ sh ows his affection towards his father. The first line of the first stanza, â€Å"The whisky on your breath†, does not necessary mean that his father is drunk. He may enjoy a drink before going to bed. He hung on to his father like death while dancing because it is a rowdy waltz. The use of the word ‘death’ can mean that he was enjoying the dance and he has a tight grip on his father so that he did not fall.In the next stanza we find that the dancing pair makes a mess of the cans in the kitchen and her mother frown at their behavior. Other than frowning, she does not take any actions to stop her father which can only mean that it is not a case of child abuse but a father spending some time his son before the child goes to bed. In the third stanza he says that his father’s hand was battered on one knuckle. The reason can be the hard labor his father put to maintain the greenhouses.If we imagine a situation in which the boy is standing on his father’s f eet while dancing, each time his father misses a step; his ear will come in contact with the buckle. This is what he means by â€Å"My ear scraped a buckle†. The first line of the last stanza, â€Å"You beat time on my head† may mean the father lovingly putting his hand on the boy’s head with the beat of the waltz. The last line â€Å"Still clinging to your shirt† reveals the boy’s wish to stay with his father and not go to bed. The analysis of the poem asserts that it is a recollection of the happy days of his childhood.The autobiographical elements, the structure, the poem in context of the era in which it was written and a close study of the poem show that is a reminiscence of the loving memories of author’s childhood which had shared with his father. Though the poem seems to be a positive memory, there are lines, ‘The whisky on your breath’ and ‘But I hung on to like death’, which shows the violence and underlin ing danger in such a dance. The activity is exhilarating, as often with children, they are impressed by things that scare and thrill them.

Free Essays on A Lesson Before Dying A Lesson Before Dying, is a complex novel about life’s various lessons. It was written by a Louisiana native, Ernest J. Gaines and published in 1993. The story takes place in the Pre-Civil Rights South in the fictionous rural town of Bayonne, Louisiana. The major focus of story lies between Jefferson and Grant Wiggins. Grant, a schoolteacher chosen to help Jefferson become a man. Jefferson is a young man wrongfully accused of killing a white man and is sentenced to death. Gaines takes the reader through the journey of a man’s quest to help another man to become a man. I will show various ways Gaines help the reader to realize the real â€Å"lesson† to be learned. Gaines begins his novel with Jefferson’s trial, verdict and sentencing, but doesn’t provide specific names of any of those involved. By doing so Gaines is able to focus the reader’s full attention on the narrator’s thoughts and the main character, Jefferson. If Gaines had give n details about the other characters involved the reader would not have been able to focus his full energy on the importance of the things said during the trial and the effects these things had on Jefferson and the other characters. At this point it is important for the reader to take in and digest all the cruel things Jefferson’s attorney says about him. His attorney refers to him as â€Å"a boy†, â€Å"a fool†, â€Å"a cornered animal†, and â€Å" a hog†. Jefferson accepts and internalizes this degrading image of himself. From this the reader will understand why Miss Emma’s insistence that her godson die like a man is such a powerful issue. Gaines presentation of the information helps the reader to better accept the events that are to follow the trial. Gaines narrates the novel through the voice of Grant Wiggins. Grant is a black teacher at the local plantation school. The novel opens with the statement, â€Å"I was not there, yet I was t here.† In this statement the reader enters the mind of Gr... Free Essays on A Lesson Before Dying In the Novel â€Å"A lesson Before Dying† by Earnest Gaines, the characters Grant Wiggins and Jefferson are put abruptly into a position of being male role models inside of their community. Grant is put into this position because of his receiving his education, while Jefferson is put into this position in a sense of martyrdom as he is facing execution. During the passages of this book, there is symbolism which attempts to conclude that Grant and Jefferson are heroes of their community. The song â€Å"You are My Sunshine† in the novel â€Å"A Lesson before Dying† by Earnest Gaines, is symbolic of the hope the community has in Jefferson. During which the song is played in the background on page 224, Grant is attempting to get Jefferson to listen to Reverend Jefferson when Jefferson replies â€Å"Me, Mr. Wiggins. Me. Me to take the cross. Your cross, Nanna’s cross, my own cross. Me, Mr. Wiggins. This old stumbling nigger. Y’all axe a lot, Mr. Wiggins.† This quote illustrates to the almost Jesus like position that Jefferson is in by caring the burden of the community. This quote is connected to the hypothesis because Jefferson is basically the hope of the community by caring the burden of standing up to the whites in their community by dying as a man, instead of the hog that the Defense attorney made him out to be. Jefferson then replies to Grant, on page 224, â€Å"Now y’all want me to be better than ever’body else. H ow, Mr. Wiggins?† This second quote also illustrates how Jefferson is the hope of the community. This quote is connected to the hypothesis because, before Jefferson’s death sentence, he worked in the field and thought he would be no more than that, and now Grant and the rest of the community expects him to be more than what he was. In the passage on page 224 and from the quotes in this paragraph, Jefferson is struggling with the thought of being a martyr for the community and proving that he is a man and is better than ...

columbian exchange essays

columbian exchange essays The Columbian Exchange The Columbian exchange began one of the largest exchanges of many different varieties of food, animals and disease. Many which were different and from different regions of the world that had never been transported before. We take for granted that everything we have is from here and it has always been here. But through The Columbian Exchange for example, the potato that had not been grown outside South America became Irelands main staple by the 1800s. The horse which was an import from Europe changed the Great Plains and the lifestyle of Native Americans, before the horse they had had to stalk bison and run them off cliffs or trap them. Tomatoes which were exchanged became an Italian trademark. Coffee and sugarcane which came from Asia became extensive Latin American crops. Before the exchange there were no oranges in Florida, no bananas in Ecuador, no rubber trees in Africa, no cattle in Texas, no burros in Mexico, no chocolate in Switzerland and even the Dandelion was brought by the Europeans. For almost every purpose the Europeans brought their baggage meat, milk, leather, fiber, power, speed, and even manure, they brought everything! Disease was another dimension of the Columbian Exchange, with catastrophic consequences for Native Americans who for centuries were an isolated population and thus lacked adequate immunities for diseases introduced by Europeans. Eruptive fevers, like smallpox and measles, proved deadly and often wiped out over half of entire tribes. Deadly epidemics, or rapid spreading of diseases, swept over the Caribbean islands. Smallpox wiped out whole villages in a matter of months. . . . In the first century of Spanish rule (1500-1600), Indians in Central and ...

Psychology Essay Example | Topics and Well Written Essays - 3000 words

Psychology - Essay Example They encounter serious kinds of attacks frequently while some overcome them with consummate ease, depending upon the nature of stress one has to go through over a period of time. Workplace stress also entails within it issues of anxiousness at work whereby it is regarded as another kind of mental anomaly, which tears down the mind and the body in a number of different ways. Workplace stress leads to different kinds of depressions within oneself on top. The employees start feeling alienated with the tasks and feel their bodies having all forms of aches every now and so often. These people also comprehend the pressures from their job settings which in reality are of a normal nature and have little bearing on them in the real sense. The pressure-exertion effect makes them feel more stressed at the end of the day, which then again is a very perilous thing. Workplace stress can be reduced when employees know that the task they are putting their best energies at, are worth the shot and in the end, the same will help them to grow exponentially. In fact they must be apprised of their hard work and the rewards that they get. This is indeed a nice gesture which means a lot on the part of the hard working and committed employees and workers (Harmon 2003). The hard working employees should balance their work commitments with their physical and mental needs as 100 percent commitment can only be made possible when there is zest and enthusiasm from within and not when a person is made to do one thing or the other by force or against his wishes. The reason why one should believe this approach will work is because in the initial sense, it will build a strong rapport between the firm and its employees and also it will convey a strong message that the organization does not compromise on the needs of the employees who are working for it day in day out just for having that extra bit of work completed by them (Bergman 2003). It also means that the organization is thorough and profes sional in its approach and is not willing to surrender in a rat race when the talk goes out loud of competing within the relevant industry or even with companies just for the sake of nothing but competition. The intensity within organizations is pretty much understandable but the madness should not be substituted on the part of the employees and getting work done out of them so that the figures could be reached and new records could be broken within the shortest possible time is nothing but insanity to say the least. Other useful workplace stress removing remedies are accounted for in the form of exercising regularly, having an intake of healthy diet, taking proper sleep, developing trustworthy social support regimes and more than anything else enjoying quality family time (Linton 2000). The physical and psychological implications thus have direct and serious effects on the way the employees look after their work tasks and thus the bottom line remains all jammed up for a number of r easons – most of which are related with stress in one way or the other. It is true to state that workplace stress affects employees at all levels which could include the physical, emotional, cognitive and behavioral stages. The physical indications entail the speech difficulties and complexities, headaches, ulcers, infertility issues, fatigue and sudden weight loss and

Motivation of Employees In Ainu Shamsi Hauliers Limited - Essay Example A presentation of the results and findings and its intrinsic analysis follows suit, after which a summative conclusion is afforded, and befitting recommendations geared to abate unbecoming organizational human resource dynamics ultimately propounded.This paper declares that  depending on our level of motivation, it may function to further determine the quantity of effort we infuse into our work, thus out rightly augment the standard of output. Employee motivation indicators capture the propellants of commitment, creativity, and energy levels by workers of a company on their jobs. They describe the psychological forces determining an individual’s effort level, level of persistence and behavior within an organization.  Numerous business managers are contemporarily ill aware of the effects that motivation can engrain in business. It is therefore pertinent that they learn and comprehend factors that function to determine positive motivation within the workforce. The size of th e business not withstanding; whether the intent is to obtain the best output out of thirty of your staff or only one, everybody requires motivation of some for.  Motivation is a paradigm approached through different facets by different businesses. It therefore emerges that the responsibility ascribed to its integration lies with the entire immediate supervisors of staff. It is the mandate of the business owner to initiate motivation as a strategic guideline for the attainment of organizational goals.   I therefore categorically assert that it is exigent to review the key factors or indicators in the motivation of employees, in order to facilitate affirmative work output in the organization. Literature Review Motivation is a function performed by mangers to encourage, impel, and inspire personnel to take action. In order to motivate employees, they must be reached, and reaching them entails a holistic comprehension of their make up’s complexity. Efforts of motivation must be directed at improving the organizational operation. However, for these efforts to be effective, they must also be designed in a way that exhibits benefits to employees. In actual fact, motivation can be accomplished aptly in the event that workers have the capacity to merge personal ambition with the objectives of the organization (Lundin and Christensen 2000). The existent relationship between the employee and the employer should be one characterized by understanding so that the employee is able to identify with his work as well as with his affiliate business. Deficiency in motivation consequently affects productivity. Several symptoms may point to low morale; increased number of grievances, high absenteeism, high number of defective products, and high employee turnover (Bowles and Cooper 2009). A motivated employee is loyal, and being loyal implies the employee’s support of the firm’s actions and objectives. In fact, the job’s appearance as a whole carries a bearing on the willingness in addition to the

The reason they are still considered is because there are less than 5% of ‘good people at detecting lies’ are easily deceived and most out of empathy or emotions may not distinguish truth from lies (Roth, Williams, Phifer, & Twentieth Century Fox Home Entertainment, Inc, 2010). Voice technology through use of lie detectors may be of use in enforcing the law by distinguishing those telling the truth from lies. However, the limitations of trained liars and some honest, people may fail to be recognized leading to injustice. It is not always favorable to use them. In the last few decades, technology/scientific development has taken place in many areas and this affects us on the both a personal level and within our professions. Lie detection, a form of voice technology has been growing widespread and available, especially in law courts to investigate the truth.

Definition aspects of empathy Essay Example for Free

Definition aspects of empathy Essay When empathy is defined cognitively, the construct of sympathy is found to be similar to a traditional measure used for studying the interpersonal sensitivity or perception of a person. This translates to a highly empathic person being skilled at decoding cues related to another’s feelings or behaviour and hence is accurate in predicting another’s feelings or behaviour. This in turn translates to the ability to infer the target individual’s thoughts, feelings and personality characteristics from a variety of verbal and non-verbal cues. Hence this definition and measurement has important applications in areas of processes involving social influences such as teacher-student, physical-patient relationships. Another definition moves beyond the understanding of another person’s emotional state or situation. It emphasises on the vicarious emotional reaction that is occur in the observer as a result of understanding the emotional state of the other individual. Here empathy is a state of emotional arousal that comes from the apprehension or comprehension of another’s affective emotional state. For example, if an individual observes another person who is sad and then feels sad themselves, then the person is experiencing empathy. This can also be translated in case the individual’s emotion is positive and the observer feels similarly positive. Empathy can be experienced over a wide range of emotions. (Randall, et al, 2001) Major Components of Empathy Although there are various definitions for empathy, it is widely accepted that there are three primary components. The components can be listed as follows: (i) an affective response to another person, often involving sharing of the person’s emotional state; (ii) a cognitive capacity to understand and take the perspective of another person; and (iii) regulation of emotion. According to Hoffman, empathy is largely involuntary response to affective emotional cues from the other person. Batson et al (1997) associate empathy with intentional role taking ability which taps into the cognitive resources. These two different aspects of empathy takes into affect depending on how empathy is triggered. Depending on the trigger the behaviour of the observer is automatically mimics the expressions of other, which is the bottom-up processing. Top-down processing happens when the observer uses his or her capacity for imaginative transposing of oneself into the thinking and the feeling of the subject. Both the aspects of empathy are involved differentially depending on the situation. (Decety, et al , 2006) Empathy and Its Use in Health Industry In the recent years, it has been found that empathetic communication enhances the therapeutic effectiveness in a clinician- patient relationship. It also helps in increasing the effectiveness of gathering information in the clinical interviewing process. In medical care, empathy improves the communication and provides several advantages. Some of these advantages are improved health for the patients, better patient compliance, reduction in risk in terms of medical legal aspects, and improved satisfaction among the clinicians. Empathy is the key element that enables better communication. Frederic Platt devised a set of key steps to effective empathy. This includes the following aspects i. Recognising the presence of strong feeling like fear, anger, grief, disappointment and other’s emotions in the clinical settings; ii. Pausing to imagine how the patient might be feeling at a particular point of time; iii. Stating the perception of the feelings of the patient. Examples of such statements are â€Å"I can imagine that must be like.. † or â€Å"It sounds like you are upset about †¦Ã¢â‚¬  iv. Legitimising the feeling of the patient; v. Respecting the patient’s effort to cope with the discomforts and issues; vi. Offering support and partnership for solving the predicaments. This could be expressed in statements such as â€Å"I am committed to work with you to†¦Ã¢â‚¬  or Let’s see how we can solve this together. † For other areas such as psychiatrists or mental health personnel, it is important to be aware of the opportunities for empathy when they arise during the interview with the patients. Here it may not be important for empathetic communication as such. The opportunity of empathy arises from the patient’s emotion. This emotion may be directly expressed or implied by the patient. When this emotion is expressed, it provides and opportunity for the physician to respond empathetically. Wendy Levinson studied the frequency of empathy opportunities with over 116 office visits to primary care and surgical physicians. In more than half of the cases, it was found that the patients presented the clues in subtle ways, not overtly. In just 38 percent of the surgical cases and in 21 percent of the primary care cases, the physicians responded to the clues. In other cases, the physicians missed the opportunity for empathy. It is usually possible to find medical clues in the fabric of the discussions about the medical problems. If the physician is busy attending to the biomedical details of diagnosis, then they are likely to miss the opportunity for empathy. Most of the times, the patients are likely to provide the opportunities again, and in some cases multiple times. Once the empathy opportunity is found by the physician, it is essential for the physician to offer a gesture or statement of empathy. The statements of empathy can be categorized into different groups. The key groups are queries, clarifications and responses. Examples of queries can be similar to the questions such as â€Å"can you tell me more about that? †, â€Å"what has this been like for you†, â€Å"how has all of this made you feel? †. Clarifications can have the following forms: â€Å"Let me see if I have got this right.. † â€Å"Tell me more about †¦Ã¢â‚¬  â€Å"I want to make sure I understood what you have said†. Responses have the following forms: â€Å"Sounds like you are .. † â€Å"I imagine that you must be.. † â€Å"I can understand, that must make you feel †¦Ã¢â‚¬  In most of the cases, the patients express agreement to the statements and confirm the feeling. In case the physician has not understood the patient’s experience exactly, then they can use Hypothesis-Test –Feedback Loop. It allows the patient to clarify their experience and also allows the physician to clarify his or her experience. This allows the physician to reinstate the empathetic statement that was missed in the earlier attempt.

Platos Views on the Technology of Writing Essay -- Expository History

Plato's Views on the Technology of Writing In the book Phaedrus Plato offers a lot of criticism for a writing technology that not many of us would ever think as writing technology, let alone criticize it. This writing technology is none other than writing itself. When people think of writing technology they mostly think of the printing press, the computer, the typewriter and such. Yet no one stops to think of writing. Writing has had such a major impact on society that who would ever think that the one of the greatest minds of all time opposed it. Plato was not just a crazy old man afraid of change; his criticism can still be applied today. For many people, writing has always been around. It’s hard to picture life without writing, books, reading, but at one point all there was was rhetoric. People would entertain themselves not by picking up a book by Jane Austen or Shakespeare. They would go to listen to people give speeches. This is what Plato was used to, and when writing came along he resisted the idea that this new invention, writing, could be good for people. First, Plato thought that writing would be bad for peoples’ memories. He thought writing would encourage forgetfulness and that people would rely too much on writing as a means of recollection. In Phaedrus Socrates points this out to Phaedrus by telling him a story about the Egyptian king Thamus and Theuth an inventor of many arts. â€Å" For this invention of yours will create forgetfulness in the learners’ souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves† (Plato 87-88). Plato used the character of Thamus to express his own concerns a... ...ted to, Phaedrus could change his speech. Authors don’t really have that luxury. Once a book is in print, they can’t change their mind. For example, say a critic says that an author’s introduction was horrible and should be rewritten. The author doesn’t get the chance to rewrite the introduction. Chances are there are already multiple copies of the book in the bookstores or libraries. As it can be seen, even though Plato brought up these critiques along time ago they can still be applied to life today. As it turns out Plato was not crazy after all, but was able to see the flaws in writing that still plague it today. In addition, these critiques he brought up can also be applied to other forms of writing technology. Works Cited: LaRocque, Paula. â€Å"Language and Lost Credibility†. The Quill. Nov. 1999: 38 Plato.

Pumps & Physics Essay

What’s new? When I was thinking about which aspect of physics to investigate for my investigation, I knew it was a good idea to choose something that really interested me. At the time I was becoming more and more fascinated by subatomic particles. I liked the fact that much of it was new and not understood properly, unlike the classical physics that everyone associates the subject with. Unfortunately, high energy physics does not translate into good practical coursework. However, while reading Six Easy Pieces, a book adapted from Richard Feynman’s famous textbook The Feynman Lectures on Physics, I noticed that a very common everyday phenomenon is still not properly understood by physicists. Encouraged by the prospect of discovering something new, I read on. Chaotic ideas Feynman wrote (on page 66) â€Å"There is a physical problem that is common to many fields, that is very old, and that has not been solved†¦It is the analysis of circulating or turbulent fluids†¦No-one can analyse it from first principles† â€Å"Wow – something science can’t explain† I thought. I looked on the internet for further details and I found a poster from World Maths Year 2000 (http://www.newton.cam.ac.uk/wmy2kposters/march/), showing just the type of unpredictable fluid motion that Feynman was writing about. It’s a new and exciting branch of maths called chaos theory and it is just beginning to be understood mathematically. The main idea is that simple systems can show very complicated behaviour that seems to have no repeating pattern. The sums that describe these systems are difficult to get your head round and appear to be way beyond my abilities as an A-Level maths student. Despite this, I felt something chaotic was an excellent phenomenon to look into for this task – it’s a chance to do some experimental work where there isn’t a perfect formula or a flawless explanation in any textbook. I couldn’t rely on distorting my results to fit a simple law, so my experimentation had to be rigorous. Limitations It was important to find a subject that was practical to investigate at school. While I was watching water swirl down the drain as I filled the kettle at home, I wondered how widely-used machines like ship’s propellers cope with the unpredictable world of chaos. Propellers have an unusual and distinctive shape designed to reduce turbulence. I wanted to investigate why this particular shape works so well – and if it can tell us anything about turbulent flow. Conveniently, water and propellers are easy-to-use in school labs (or so I thought!). Best of all, I thought, if I could model the situation but ignore the effect of turbulent water, I could look at the mechanics of the propeller, and then compare the theory with what happens in real life. It seemed like a good mix of fresh ideas and traditional physics problems. I talked about my plans to some of my teachers and one of them mentioned that his son had done a PhD degree in the formation of bubbles by marine propellers – an effect called cavitation. This encouraged me to continue with this project, knowing that it relates to current areas of research and is an important and worthwhile topic. Research It turns out that one of the most interesting applications of pumps is in fire engines. As fire services are public organisations they make available plenty of high-quality, free information online. Engineering sites were also useful. * The Physics Behind Firefighting American high-school physics project http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/Matt_Taylor/Matt1.dwt * How Fire Engines Work General information http://science.howstuffworks.com/fire-engine.htm * Bedfordshire & Luton Fire and Rescue Service My local fire brigade, who I actually went to visit to find out more http://www.bedsfire.gov.uk/index.htm * American Turbine: Pump Calculations Web-based program for working out quantities in pumping http://americanturbine.net/formulacalc/pump.htm * Impeller Design The engineering that goes into pumps http://homepage.mac.com/mrbach/mixdesign.htm * Firefighting.com Useful data on pumps but uses frames so I can’t give a full URL http://www.firefighting.com * How Things Work A simple explanation of propellers and aerofoils Lesley Firth, Kingfisher, 1983 p13 * The Physics of Firefighting Some simple principles explained Physics Teacher, vol 28, p 599 * Firefighting Contains a bit of physics but interesting background information Jack Gottschalk, Dorling Kindersley, 2002, ISBN: 0789489090, p128 * Go with the flow Article about modelling granular and fluid motion New Scientist, 2 August 2003, p38-39 Preliminary Experiments I wanted to find the most efficient propeller design. From research I found out that propellers have different shapes for different tasks, so my first goal was to get a propeller up and working, and then look at what I could change to make it run more efficiently. These are the variables I aimed to evaluate for their effect on power transfer efficiency in preliminary tests: * The speed of rotation * The size of the propeller * Since speed of rotation is less time consuming to collect data for, I’ll look at it first. I intend to plot a graph of speed of rotation vs. output flow rate. Considering the shape of a ship’s propeller, I expected to be looking at these variables later on: * The number of blades on the impeller * The shape of the blades * The orientation of the blades (what angle they are in relation to the axis of rotation) The physics principles that are important here are mechanical ones. The efficiency of the propeller depends on how much of its power goes into pushing water outwards and how much is wasted on heating the water up or causing it to form whirlpools. New Scientist’s article Go with the flow mentioned the Bernoulli Effect, which is observed on aircraft wings and on propeller blades. Lower pressure Higher pressure A blade with a curved plane and a flat plane forces some air or water on a longer route over the curve, and the rest takes the shorter flat route. The longer journey over the curved plane causes a drop in pressure, which translated to lift in planes, and thrust in propellers. According to all the textbooks, the optimum number of blades, the blade angle, the speed of rotation and the size of propeller all contribute to the efficiency. It seems like I’ve got my work cut out for me. I’m going to concentrate on rotation speed and its effect on water flow rate outwards. Let’s see what the preliminary tests show. Water flows in Axle Propeller Watertight casing Water flows out Planning Risk Assessment1,2 Apparatus or procedure Hazard Precautions All apparatus Accident or fire Supervise the experiment at all times and clear away at the end of the session. Store all equipment safely and securely. Boiling water for shaping polypropene propellers Risk of scalding Take care with boiling water, paying attention at all times. Stand well back from the saucepan and do not move it while the water is hot. Use a heat-insulating towel to manipulate the hot polypropene. Electric circuit in general Risk of fire from short circuiting etc. Use insulated wires, keep connections clean and dry, and always supervise the apparatus while current is flowing. Do not leave the set-up unattended without unplugging the mains supply. Use wires of appropriate diameter to prevent overheating resulting in fire. Rapidly rotating propeller Possibility of injury from contact with rotating blades of propeller Leave motor switched off until ready to record data. Take care to keep your distance from the propeller, especially fingers. Heavy equipment (power pack, retort stands) Falling equipment could injure Ensure stands etc. are sturdily placed and avoid placing equipment near the very edge of the work bench. Power pack Output: 13V 5A DC Input: 230V mains AC Risk of electrocution from mains input (risk of injury from output voltage is minimal) Keep power pack away from the wet part of the apparatus (to prevent conduction through water). In my experiment, I will keep all the electrics on a shelf above the level of the water-containing apparatus. Ensure all water-containing equipment is as waterproof as possible, and have towels to hand to soak up spills. Do not leave the set-up unattended without unplugging the mains supply. Preliminary findings In the research and rationale section, I identified variables I wanted to investigate. I conducted preliminary experiments to found out which variables were the most practical to focus on. The basic aim is to narrow my search down to one or possibly two variables and then find the most power-efficient value for each variable. Size of propeller was very difficult to control since I found that the propeller will only stir the water unless it tightly fits the container. Small propellers did not displace any water. Only propellers with a diameter 1 or 2mm less than the diameter of the container were effective in pumping water. As such, I decided not to consider investigating this variable. Angle of propeller blade inclination is possible to vary, but I found the range of angles possible with the materials I had chosen were too limited. I developed a method of cutting out rectangles of polypropene sheeting, boiling them in water and bending them to the right shape, but the blades often snapped and it was tricky to get the blades to remain at the chosen angle as they cooled and hardened. I decided to keep blade inclination constant. 45à ¯Ã‚ ¿Ã‚ ½ might seem to be an appropriate angle of inclination to choose for all the propellers I will compare, but most propellers I found photographs of from my research showed shallower angles of blade inclination. I have decided that all my propellers will be inclined at 30à ¯Ã‚ ¿Ã‚ ½ because it is easier to make the propellers this shape and I assume that this is a more efficient angle than 45à ¯Ã‚ ¿Ã‚ ½ since many propellers are about this angle. Speed of rotation turned out to be very simple to control with the use of the variable voltage power pack. I investigated the effect of power input on rotation speed (or angular velocity of the propeller as I call it from here on in). Using a stroboscope, I determined the linear relationship between the voltage supplying the motor (V) and the angular velocity (?) of the propeller shaft in air. I adjusted the frequency of the strobe light until the propeller appeared not to rotate. At this frequency, the time between flashes of the strobe and the time for one blade of the propeller to reach the former position of the blade before it is equal. If you find the angle in radians (?) between two adjacent blades and multiply it by the frequency (f) of the stroboscope (the time between flashes), you are left with the angular velocity (?) of the propeller, i.e. the rate of rotation. ? = ?f In the table below, V and f were determined experimentally and ? was calculated by multiplying f by ?. Since the frequency is only known to two significant figures, the angular velocity can only be determined to 2 s.f. Angle between blades, ? degrees 72 Angle between blades, ? radians 0.4? V V 0 2.25 4.25 6.25 8.75 10.00 13.00 à ¯Ã‚ ¿Ã‚ ½0.25 f s-1 0 13 26 36 50 57 74 0.5 ? rad s-1 0 16 32 45 63 72 93 0.5 Once the propeller is immersed in water the relationship between ? and V changes. The relationship is non-linear and, unlike the graph above, is different for every propeller. In light of the preliminary experiments I will modify this method to vary the power supplied to the drill that drives the propeller. It will not matter that the speed of rotation varies depending on how much the water resists the motion of the propeller. The only data that are needed to calculate the efficiency of the system are power input and useful power output. Efficiency At this point it is important to mention that I am concentrating on the efficiency of the propeller at displacing water. Percentage efficiency = useful power output / power input à ¯Ã‚ ¿Ã‚ ½ 100%, or rewritten in symbols, ? = Puseful out / Pin. Also, power input is proportional to input voltage since current is constant at 5 A in my equipment. P = VI and I = 5   Power (Watts) = 5 x voltage (Volts). Review of purpose of investigation The focus of this investigation is to determine the optimum number of blades for a propeller to have to maximise energy-efficiency. Experiments will compare propellers with 2, 4 and 6 blades. The energy efficiency of the three propellers when displacing water will be determined and compared. Their efficiency may not be independent of the rate of rotation. This too will be investigated and analysed. The analysed results will show which of the three propellers is most energy efficient in at each rate of rotation investigated. Extract from Eric Weisstein’s World of Physics http://scienceworld.wolfram.com/physics/Screw.html A screw is a simple machine that is actually a version of the inclined plane. The pitch of the screw corresponds to the inclination of the plane: a higher pitch (i.e., more threads per length) means less inclination, and thus easier turning, but also more turning that needs to be done to travel a given length. As with the other simple machines, the required force is reduced, but the amount of work done is the same. Apparatus 13V max. variable voltage power pack Retort stands and clamps 15 cm ruler Silicone polymer window sealant Garden hosepipe Expanded polystyrene for supports Multimeter (0.25V, 0.25A tolerance) Polypropene sheet for making propellers PET lemonade bottles (2 Litre capacity) Plastic funnel for filling Stopwatch Collection bottle with 2 litre mark ( 0.002 L) Cordless electric screwdriver/drill Steel axle Volumetric burette PET pudding basins to contain propeller Water Colour-coded wires and crocodile clips Saucepan, hotplate and tongs for heating and reshaping polypropene into propellers Scissors and craft knife for cutting out propeller shapes from polypropene sheet Apparatus set-up These diagrams show how I designed the equipment. The circuit diagram connected to the drill represents the power pack, and its voltage selector is displayed as a variable resistor. The plastic volute is the container that houses the propeller. To begin with, water fills the water tank and the plastic volute. Activating the power pack supplies an electric current to the drill, which rotates the propeller. Variables to control Variable How I will control it Viscosity of water Constant at constant temperature and pressure Power and speed of rotation of propeller Use a power pack instead of a battery to supply the cordless drill. Use the same power pack, axle and drill throughout the experiment. Rotation speed does not vary linearly with power but carefully designing the experiment can avoid problems. Room temperature and pressure Constant at 20à ¯Ã‚ ¿Ã‚ ½C due to central heating. Atmospheric pressure changes are insignificant to this experiment. Plan for laboratory sessions Session and duration Targets Before lab work begins Build the waterproof sections of the apparatus and seal them with silicone polymer. Buy a cordless drill. First two hours Set up all apparatus, construct the propellers and test the experiment to ensure it works as planned Second two hours Measure the time taken to raise 2 Litres of water through 50cm vertically by each of the three propellers, with 65W power input Third two hours Repeat the previous session’s experiment, but with the power set at 35W. Fourth two hours By considering the results collected before this session, decide which range of power input to investigate in detail Fifth two hours Continue gathering results for chosen range of power inputs Remaining time Investigate turning points and anomalies as necessary In between lab sessions Complete results tables, draws graphs as appropriate and start to analyse findings. Use analysis to modify strategy and to make decisions on how to progress. While I was designing which equipment to use and how to use it, I thought carefully about accuracy and sensitivity. The major difficulty with this experiment is the unpredictable nature of the propellers – unlike many other things physics, it is not easy to find a good estimate of what will happen in textbooks or online. One way of ensuring good results is to measure the variables to a reasonable number of significant figures. The multimeter I chose to use is quick to respond to changes in current or potential difference and has fine graduations on its scale, providing high sensitivity. It also has very tight tolerances as it is designed for use in high performance electronics, which contributes to the accuracy of the results I will gather. The multimeter is significantly more accurate and sensitive some of the digital alternatives at school. It responds to changes much quicker too. I have had to design and build quite a large amount of equipment just to make this project possible. To measure the volume of water pumped out by the system, I will calibrate the water collection bottle with graduations. To make sure they are very sensitive and accurate, I will use the high quality, high accuracy laboratory glassware available at school for use in chemistry and biology. The percentage error on the volume graduations on these pieces of equipment is very small (around 0.0003%). References for planning section 1.

In these experiments, the temperature and pressure have been constant at 293K (20à ¯Ã‚ ¿Ã‚ ½C) and 105 Pa respectively. Under these conditions, water has a density of 998.2 kgm-3 (according to the Nuffield Advanced Science Data Book, Nuffield-Chelsea Curriculum Trust, Longman, 1984). Therefore, the time taken to raise the water and the number of blades on each propeller are the only variables in my experiment.
