Mary Shelley: Submissive Women in Writing
In the writing of Mary Shelleyââ¬â¢s Frankenstein or, The Modern Prometheus, she creates four submissive female characters all of who are negatively affected by the hands of Victor Frankenstein. These four submissive female characters are Agatha, Safie, Elizabeth, and Justine.Each of these women is proposed as passive and nonessential. The women, Agatha, Safie, Elizabeth, and Justine, make a pathway for the creation of action for male characters. The actions that happen with/to these women negatively affect them for the purpose of teaching one of the male characters a lesson or inflicting deep emotions to the male characters.Agathaââ¬â¢s purpose to man in this book was teaching the monster. ââ¬Å"The girl [Agatha] was young, and of gentle demeanourâ⬠¦she looked patient, yet sad.â⬠(Shelley 75, 76). Agatha teaches the monster many things mostly by him observing her interactions with her blind father and studying her actions and mannerisms. ââ¬Å"Agatha listened with r espect, her eyes sometimes filled with tears, which she endeavored to wipe away unperceivedâ⬠(Shelley 80). Agatha teaches the monster about respect, sensitivity, and human relationships.Safie, a close friend of the De Laceyââ¬â¢s, comes on horseback to the cottage. Safie is Arabian and doesnââ¬â¢t know or understand english, so the De Laceyââ¬â¢s give her lessons. Safieââ¬â¢s lessons in language and culture become the monsterââ¬â¢s lessons as well. ââ¬Å"My days were spent in close attentionâ⬠¦ I improved more rapidly than the Arabianâ⬠¦I comprehended and could imitate almost every word that was spokenâ⬠¦ I also learned the science of lettersâ⬠(Shelley 85). Safie is another passive female character that caused action by the monster. To the audience it is insignificant weather or not Safie learns english, but it is furthering the monsterââ¬â¢s education. Thus it was for the sake of teaching a male character a lesson and of no real benefit to t he female character.Justine is one of the most passive, submissive female characters and hardly even has a voice in the novel. Justine is ultimately framed for the murder of William Frankenstein, yet she remains collected and serene. Justineà handles herself with poise even with her unfortunate circumstances.ââ¬Å"God knows how entirely I am innocentâ⬠¦ I rest my innocence on a plain and simple explanation of the facts which have been adduced against meâ⬠(Shelley 56). Justineââ¬â¢s purpose becomes clear when she is framed. She becomes static, a victim of her circumstance.Mary Shelley describes Elizabeth as submissive and tender. Elizabeth is the most influential character associated with Victor Frankenstein, causing a roller coaster of emotions. Mary Shelley writes Elizabethââ¬â¢s submissiveness quite obviously when she says, ââ¬Å"she presented Elizabeth to me as her promised gift, I [Victor], with childish seriousness, interpreted her words literally, and looked upon Elizabeth as mineâ⬠¦since till death she was to be mine onlyâ⬠(Shelley 19).This belittles Elizabeth and essentially makes her a victim of the monster because of her relationship with Victor. Even when the monster threatens Elizabeth, Victor doesnââ¬â¢t try to protect her entirely, and puts his frustration with the monster over Elizabeth. Elizabeth is belittled along with the other female characters, making them mere tools to get revenge.There is one more hidden female character, without whom, the novel would not succeed. Margret Saville is the most passive, submissive female character. There is no way to know if she even exists entirely, but her significance is one of great magnitude.Margret Saville is the reason Robert Walton writes the letters explaining what has happened and what Victor has told him, thus creating the whole story. Margret is so submissive that she doesnââ¬â¢t even get a voice in the novel; there is never a response from her.Mary Shelley creat ed many submissive female characters, all of whom were used, objectified, and castaway after greatly impacting manââ¬â¢s life. They are used as tools of revenge and decried for the works of the men who used them.
Bullying and Violence in the Workplace
The problem, the results, and possible prevention strategies ill be presented based on an invited paper by Bowen, Private, and Bowie (201 1), ââ¬Å"Reducing workplace violence by creating healthy workplace environments) and a peer-reviewed Journal article, ââ¬Å"Effectiveness of Bullying and Violence Prevention Programsâ⬠(Stag, S. , Sheridan, D. , 2010). Bullying and workplace violence can be controlled if management takes appropriate steps toward early recognition, education, and preventive practices.Identifying the potential for violent behavior often concentrates on plotting the ââ¬Å"bad appleâ⬠, the employee constantly contradicting authority, complaining, verbally busing others, gossiping. Or alienating staff. According to Bowen (2006) It may be a reaction to bad or unhealthy environment referred to as the ââ¬Å"bad barrelâ⬠. The policies, procedures, and practices of an organization have recently come under scrutiny as a possible cause of workplace violence . If the atmosphere for nurses, other staff members, and even patients is oppressed, violent, or unsafe, then those affected may resort to violent behavior as a response mechanism.Management must be wiling to look at the tone and practices of the organization and evaluate staff perceptions. If the staff sees the organization in a negative light immediate steps must be taken to correct course and alter perception. Employee productivity and retention are tied closely to the staffs feelings toward the values and practices of the institute. Pride, esteem, excellence In service, caring, open-mindedness, team-spoilt, recognition of accomplishments, fairness In decisions, and constant development and improvements all solidify an employee's loyalty and desire to produce excellence in all workplace activities.Bullying and potential violence can come in many forms both covert and overt. Some red flags would include an employee who has a noticeable change in behavior, verbalized threats, intim idation, harassment, and repeated confrontational behaviors. These individuals must be counseled since these changes may be signs of personal or social turmoil in the individual's private life that is affecting workplace attitudes. If counseling, warnings, diffusing violence / anger management classes are not effective, the individual may face termination for the health and safety of him or herself as well as others (Libber, 2011).Many classifications of types of bullying have been used over the last 10 or more ears, One example Is the taxonomy developed by Earner and Hole (1997) which covers most of the commonly listed categories: I) threat to professional status, ii) (Discover, Mac Carjack, & Kashmir, 2005, p 441). Lynn Libber in the Winter 2011 issue of Employment Relations Today offers four simple but concrete guidelines to address and curtail workplace bullying and violence that can be readily implemented by management.The list includes thorough background checks for all perspe ctive employees watching for signs of previous violent behavior and discipline problems. Create a workplace ââ¬Å"Violence Protectionâ⬠logic. Communicate the policy to all employees and be sure to explain the forms of bullying and harassment (including internet / cyber bullying), the consequences of unacceptable behavior, and disciplinary steps leading to possible termination for repeat offenders.Train all new hires immediately during orientation and all other employees annually about ways to prevent (primary prevention), De-escalate (secondary prevention), and personally respond (tertiary prevention) to workplace violence and bullying (Bowen, Private, & Bowie, 2011, p. 188). This would include arioso positive and negative reactions to bullying such as confronting the attacker or reporting to superior versus avoidance or quitting Job (Discover, Mac Carjack, & castrate, 2005, p. 451).Once the implications and functions of violence in the workplace are fully understood by organ izational managers, then an effective policy ad methodology can be created which will effectively address this spiraling problem, provide a safe environment for all, and raise the level of care within the institute. An introspective analysis of the current work climate ad changes that can be implemented to improve am spirit and loyalty will pave the way for better employee relationships, a stable, secure, and focused workforce.

The American Way: Courage, Pride, and Honor
The American Way: Courage, Pride, and Honor ââ¬Å"These are the times that try menââ¬â¢s souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country: but he that stands it now, deserves the love and thanks of man and woman. â⬠These words, uttered by the great Thomas Paine on December 23, 1776, embody the true courage and sacrifice of the many American Patriots during the earliest stages of our country. It is words and ideals such as these that shaped and molded our country into the place we know it as today.As both an American citizen and student of US history, I believe that a manââ¬â¢s true character reveals itself in times of adversity. The leaders emerge and men and women of smaller fortitude weed themselves out, sometimes sooner rather than later. The early stages of our country were marked with great struggle and rebellion against the powers that kept us down. There has been struggle throughout the entire histor y of our country, and still is today, but not many quite like our struggle to gain independence and freedom.Our country made its first true attempt to gain independence from King George the III by declaring ourselves an independent nation free from any bondage to Great Britain. This led to the Revolutionary War, in which over 4,000 men gave their lives and another 6,000 were wounded, in the attempt to gain freedom for all Americans. General George S. Patton later explained what drove these men to go to any length for their country when he said, ââ¬Å"The courageous man is the man who forces himself, in spite of his fear, to carry on.Discipline, pride, self-respect, self-confidence, and the love of glory are attributes which will make a man courageous even when he is afraid. â⬠Thousands of men have died throughout the history of this country so that we may be able to live the life we live today, with nobody ruling us and the freedom to worship as we please, live how we please, and aspire to make the most out of ourselves in every aspect of life. Our country takes pride in the men and women who have given the ultimate sacrifice for their country, and hopefully we shall never be so foolish to forget the sacrifices made.We fly our flags at full height to remember these men, we celebrate independence day, and we celebrate veterans day because we need to remember the violence and adversity in order to appreciate the peaceful and prosperous lives we are able to live today. Iââ¬â¢ve already spoken about the freedom fighters in the beginning of our time as a nation. However, many others have fought for freedom and equality in order to shape our nation into what it is today. The African-Americans had to fight in the 1960ââ¬â¢s for equality.Imagine coming to Lackawanna College and whites and blacks drinking from separate water fountains and eating in different cafeterias. This would truly be a sad representation of the character of the average American man. Even before this the Irish immigrants were hated and discriminated against, but also the Italian and Polish immigrants. So many people have struggled and persevered for the better of our nation. I believe the American experience is one of courage, hardship, perseverance, freedom, and equality for any man who chooses to come here and pursue these ideals.John F. Kennedy described perfectly the importance of these beliefs and standards when he said, ââ¬Å"Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear an burden, meet any hardship, support any friend, oppose any foe, in order to assure the survival and success of libertyâ⬠¦ We dare not tempt them with weakness. For only when our arms are sufficient beyond doubt can we be certain beyond doubt that they will never be employed. ââ¬

Causal Argument video games make children obesity Essay
Causal Argument video games make children obesity - Essay Example All the above causes have been substantively evaluated and proven to have a direct impact on obesity; however, debates have recently ensued, concerning the relationship between video games and obesity. According to a study by WHO, video games are the leading cause of obesity in young children and teenagers; the research further shows that a third of children in different parts of the world are overweight (Ingham). Video games make children fat, given that screen time takes away time for healthy lifestyle habits such as dieting and vigorous games. This paper will examine the premise that video games make children fat, by highlighting a number of facts in the relationship between obesity and video games. One way in which video games cause obesity in children is that video games replace active play and exercise, thus making the children physically unfit. It is advertent knowledge that obesity is high in those people who do not exercise regularly to flush out excess calories in their bod ies (ââ¬Å"Obesityââ¬â¢). This is so because vigorous physical exercises require a lot of energy; the body can only get by burning the excess fats stored in the body as an alternative source of energy. Physical activity also tends to reduce the levels of hunger in obese individuals, besides enhancing their bodiesââ¬â¢ ability to metabolize fats. ... Many studies have recently shown that, on average, children absorb up to 163 more calories when playing video games than they would when not playing (ââ¬Å"Video games make kids fat ââ¬â studyâ⬠). This trend has been linked to the emotional stress that video games have on children, creating the need for a reward; unfortunately, children tend to eat mainly sweet and fatty foods thus further aggravating the risk for obesity. Dietary strategies are not an option for children who are involved in video games because, being highly addictive, the video games make children insensitive to nutrition. The glee of fatty, sugary foods is every childââ¬â¢s ultimate reward for the extreme mental and emotional stress that accompanies playing video games. Coupled with a lack of vigorous physical exercise, excess calories in children are a complete recipe for obesity. Obesity also results from psychological factors such as negative emotions of boredom, anger or sadness (ââ¬Å"Obesityâ⠬ ); all these emotions are common in children during video games. Studies have shown that many overweight people usually have emotional or psychological problems, which affect their eating habits accordingly. When playing video games, children are prone to extreme emotional stress or psychological problems, which emanate from their high involvement in the video games. For instance, a simple act of losing a fight in a video game may provoke feelings of anger or sadness in children, thus causing emotional instability. In the event of such emotional or psychological instability, children often tend to act out in defiance response to the feelings of loss, anger or sadness. In most cases, children will respond to negative feelings of anger and frustration by eating more

Utilizing the Time Value of Money Essay Example | Topics and Well Written Essays - 500 words
Utilizing the Time Value of Money - Essay Example But do to some limitations of these tools other tools such as Profitability Index and Payback Period. The payback period determines the duration of the time it would take to recover the investment made initially. This will give us the number of periods it would take to breakeven for the initial investment made. The profitability index is used as well in investment decisions because it measures the value created per dollar invested. So if the PI shows a greater than 1 value, then it means that the investment is returning a greater amount than invested. These two techniques are used because they resolve the disadvantages of NPV and IRR methods. (Helmkamp, 1990) The first disadvantage of a NPV calculation is its dependency on the interest/discount rates. It is very difficult for the investor to know the correct discount rate since they can change though out the life of that investment making considerable differences on the decision. (Investopedia, 2008) Another issue with the discount rate is the differences in the risk factor of the investment. Since the risk can change, therefore the discount rate, this can make lives very hard in calculating NPV. (Investopedia, 2008) Another disadvantage lies in the facts that NPVs are just mathematics calculations that do not take into account the real options available for investment.

Team Performance report Essay Example | Topics and Well Written Essays - 1500 words
Team Performance report - Essay Example There are different root causes that have led to this poor performance in the team. First and foremost, it can be seen that the team members lack knowledge to undertake the new performance tasks set as a result of the changes implemented by the top management to alter the design of widgets in order to cut operational costs. Knowledge is essential among the team members so that they can meaningfully contribute to the overall performance of the organization as a whole. If the team members lack knowledge about their work, this is likely to result in poor performance. Secondly, it can be seen that the other root cause of this poor performance is that the team members lack mutual understanding among themselves. This means that there is a conflict of interests where the team members are comfortable with the traditional way of doing things in the organization while the management is anticipating something different. This causes misunderstanding among them and this can contribute to poor per formance. When there is lack of understanding among the team members, they are likely to be distracted from their work and this is counterproductive. The other root cause of poor performance in the case of ABC is that the team members lack motivation. ... They do not see any reason for putting more effort in their work since they are just treated as ordinary workers. In order to solve the problems identified above, it is imperative for the organization to promote learning among the team members so that they can exchange ideas which lead to knowledge creation. Learning is a change of relatively permanent kind which may result in new behaviours and actions or new understanding and knowledge gained from a formal or incidental life experiences (Mullins, 2010). The other strategy that can be taken into account by the management of ABC is related to human resources development. This is concerned with developing the team members so that they can keep pace with the changes that can take place in the organization. In terms of lack of understanding among the team members, the management of the ABC group ought to put measures in place that will improve communication among them. Poor communication in the organization is detrimental to its perform ance since the members will not understand each other. Open channels of communication should be put in place so that team members can exchange information when they want. It is also important for the management to put measures in place that are meant to provide feedback to team members so that they know if they are doing the correct thing in their operations. This will also help them to gain knowledge about their work and mutual understanding is likely to be promoted in the organization. In order to solve the problem of lack of motivation, the management at ABC should treat the employees as valuable assets to the organization. This can be done through involving them in the decision making process in the organization. This will help them to develop a sense of belonging to the company. If

Politics Essay Example | Topics and Well Written Essays - 750 words - 11
Politics - Essay Example pecific segment of the poo in the society that need assistance, it is because these class of people never had a chance to do what others did to enrich themselves. William Summer tries to discredit the point that the poor class in the society is really struggling under the emblem of limited resources. According to summer such claims are exaggerated and lie on the precept of poor assumptions made by the humanitarians. He speaks out by stressing the point that hard work is the key to any success. William stresses on this point when he says ââ¬Å"....men who have not done their duty in this world never can be equal to those who have done their duty more or less well. Classes will always exist; no other social distinctions can endure. The class distinctions simply result from the different degrees of success with which men have availed themselves of the chances which were presented to themâ⬠(Mayer, 17). William supports his claims logically by saying that in the society disparity in classes will always exists; the social class will always be in any given society. However, some people in this class just need a little assistance for them to get to a higher class. He supports his claims that ââ¬Å"Instead of endeavoring to redistribute the acquisitions which have been made between the existing classes, our aim should be to increase, multiply, and extend the chances. The greater the chances, the more unequal will be the fortune of these two sets of men. So it ought to be, in all justice and right reason.â⬠This essay is a true illustration of Darwinism that subjects a basis that all men have equal chances of being great, but the truth is that not all of them will attain the same level (Mayer, 45). Francis Fox Piven postulates that power in the society is construed to dominate above the less privileged. The rich oppress the poor either materially or physically depending on the dominance that is directed towards the less privileged. Piven uses the term disruption to connote
Create a proposal Essay Example | Topics and Well Written Essays - 750 words
Create a proposal - Essay Example Problem Statement Diabetes is considered epidemic amongst African American women with the rates amongst women 20 years and above recorded to be approximately 12% and 25% amongst women of 55 years and above (Kirk et al, 2007, pp 135-142). Statistics from the National Womenââ¬â¢s Health Information Center, Department of Health and Human Services (DHHS) 2002, shows that diabetes is more prevalent amongst African-American women compared to white women. Because of the high rates of mortality and morbidity recorded in diabetes-related cases, there is need for preventive measures amongst African American women population. Objectives The main objective is to examine examine diabetes epidemic among African-Americans based on the various range of risk as well as structural factors contributing to the prevalence of the disease especially amongst women. The research proposal will cover three stages which include inspection of the available sources to obtain statistics and information on usage figures. Then there will be qualitative research providing in-depth information on the issue in question. Literature Review Patient-provider perceptions and the correlation between random serum glucose concentration and glycated hemoglobin are some of the differences in diabetic related cases in African Americans and Whites. This research will show the differences between the perceptions of patients and providers on diabetes related perceptions as well as examine its association if any with self-care behaviors and with special comparisons between African-American and White patients. The research will bring to the fore front the part played by ethnic variation in the correlation between random serum glucose concentration and glycated hemoglobin (American Diabetes Association, 2009, pp 13-61). According to Dana et al 2009, the manner in which a person experiences, understands and identifies diabetes is referred to as diabetes perceptions (Dana et al, 2009, p347). Research on patient- provider differences has found congruence with regard to diabetes-related attitudes, beliefs and perceptions. Research also shows that patients and providers generally agree on the core components of effective care of diabetes but have entirely different understandings of diabetes and the priorities for self management (Burns and Grove, 2007). Methodology Qualitative Research The objectives will be answered through the application of detailed qualitative information. The research will focus on exploring and establishing the nature of reactions towards diabetes epidemic among African-Americans based on the various range of risk as well as structural factors. The study will utilize questionnaires and at the same time apply efficient procedures in line with ethical methods for data collection. There will be an eleven item demographic showing participant profile, eight items dealing with health educator profile and questionnaire with thirty-nine items. Variables in the study include; he alth beliefs, knowledge of diabetes, nutrition, physical activity, health education classes, monitoring of glucose, support from social dimensions such as families, and finances involves. Qualitative research provides ways through which the researcher presents his/her point of view on research issues

Safe Sex Communication for Young People in China Essay
Safe Sex Communication for Young People in China - Essay Example Sheeran, Abraham, & Orbell (1999) and a meta- analysis by Noar, Carlyle, & Cole (2006) found communication about condom use, which can be the most effective way for sexually active individuals to protect themselves from STDs including HIV, to be the strongest predictor of condom use. China is suffering one of the fastest growing of HIV epidemics in the world, with an annual 30% increase (Webber, 2007). Among the reported HIV infections, about 81% were young people between the ages of 20-39 (Qi, 2002). One primary factor fueling the spread of HIV is the increase in unsafe sexual behaviors. Hence it is vital to encourage the Chinese young population to engage in communication about safe sex and condom use. In this study, two theories that have been used to explore safe sex communication successfully in the US will be examined from the perspective of the young Chinese population: the Theory of Planned Behavior (TPB) developed by Ajzen (1991), and the Information Motivation Behavioral Skills Model (IMB) developed by Fisher and Fisher (1992). The determination will be made of how they could be used to successfully the young Chinese population to engage in more active safe sex communication and condom use. This paper begins with an overview of the... g this, the Information-Motivation-Behavior Skills Model (IMB), suggesting that information, motivation and behavioral skills are the three essential factors in achieving behavior change, will be examined. Finally, the application of the two theories to the young Chinese population in terms of safer sex communication and condom use will be presented. They will be compared and contrasted, and recommendations regarding the effective use of the two theories in Chinese young population will be offered. An evaluation of 10 million Chinese people will be infected with HIV by 2010 in the absence of effective preventions (UNAIDS, 2004). However, few studies have investigated safer sex behavior among the young Chinese population. Of the limited studies in this area, results indicate that it is largely uncommon to conduct safer sex behaviors, and the use of condom remains consistently low (Wong & Tang, 2001). For instance, among a total of 455 surveyed Chinese college students in Hong Kong, 24% were sexually active while only 38.2% of them using condom regularly during the year (Wong & Tang, 2001). In another study, only 14.4% of the subjects were found using condoms regularly during sex intercourse, while almost 30% (28%) had never or almost never used condoms (Wang, & Zhang, 2002). Cottrell et al. (2005), which investigated Chinese college student's sexual and HIV knowledge, found that less than half of the student (43%) had used a condom the last time they had sex. Condom use, however , was found to be the only reliable method of protection for STD/HIV for those who are sexually active (Bryan, Fisher, & Fisher, 2002). Researchers have found that consistent and correct condom use can reduce the rate of HIV transmission by 87% (Bobrova, Sergeev, Grechukina, & Kapiga,

Critical analisis essay. SPANISH Essay Example | Topics and Well Written Essays - 1250 words
Critical analisis . SPANISH - Essay Example Uno de los elementos claves que ayudan en la puesta en practica de este sistema de control es la existencia de una figura de poder, cuya identidad es de poca importancia, asi como tambien la existencia de una red de personas, cuya identidad tambien es intrascendente, que ayudan en el ejercicio del poder. De hecho en la historia la mancha indeleble el personaje principal solo puede escuchar una voz, dicha voz es incorporea y, segun el personaje principal, no podia relacionarse con un ser de carne y hueso: La voz llenaba todo el salon y resonaba entre las paredesâ⬠¦Yo no podia saber de donde salia. Tenia la impresion de que todo lo que veia estaba hablando a un tiempo: el piso de marmol negro y blanco, la alfombra roja que iba de la escalinata a la gran mesa del recibidor, y la alfombra similar que cruzaba a todo lo largo por el centro; las grandes columnas, las cornisas de cubos dorados, las dos lamparas de cristal de Bohemia (Bosch 1). Este extracto nos hace pensar que ni el gene ro, ni la posicion social, ni la profesion de dicha figura son de consecuencia. Lo que si es fundamental es que la figura no pueda ser vista por los individuos que son vigilados. Asi como tambien que el individuo crea que el sistema disciplinario, cuyo representante en la historia de Bosch es la voz incorporea, tenga un alcance total. Como ya se ha mencionado, esta figura de poder no es la unica persona en todo el sistema. Tambien hay otras personas que ejercen diferentes funciones dentro de este sistema de control. Cada individuo tiene un papel que jugar y es, a su vez, supervisado por alguien de mayor jerarquia. En Pormenores de una servidumbre de Pedro Peix, el Benefactor claramente representa la figura de poder, pero durante todo el relato hay personas, cuya identidad tambien ignoramos, encargadas de realizar los trabajos sucios. Hay personas encargadas de grabar las sesiones amorosas de la esposa del personaje principal con otros hombres, hay personas que encargadas de seducir a la hija del personaje principal, hay personas encargadas de contratar la banda y las prostitutas que se apostaron en frente de la casa del personaje principal. Y, tambien, esta la persona encargada de hacer las llamadas telefonicas que el personaje principal recibia (Cespedes). Esta claro que este sistema es extenso en su practica y que abarca todas las areas de la vida cotidiana del individuo, incluso las areas mas intimas y los detalles mas pequenos no estan fuera del alcance de este regimen. En el relato de Bosch una voz incorporea le pide al personaje principal que remueva su cabeza pues ya no la necesitaria. Y el personaje principal le indica que no puede despojarse de su cabeza tan facilmente: Deme un tiempo para pensarlo. Comprenda que ella esta llena de mis ideas, de mis recuerdos. Es el resumen de mi propia vida. Ademas, si me quedo sin ella, ?con que voy a pensar? (Bosch 2). Sin darle mucha importancia la voz le contesta que ya no la necesitaba pues ellos (los miembros d e este sistema disciplinario) pensarian por el y que sus recuerdos eran innecesarios. Un sistema como este, que no tiene ningun reparo en declarar que las ideas, las emociones y

Guns Germs and Steel Essay Example for Free
Guns Germs and Steel Essay Yali asked the question of ââ¬Å"why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had so little cargo of our own? â⬠(Diamond 14) In other words, he is asking ââ¬Å"what is the factor between our people and ours that causes human development to proceed at different rates? â⬠(Diamond 16) What Yali is really asking though, is, what is this mysterious factor? According to Diamond, the basis for development is the environment around us including the resources and the native people of New Guinea donââ¬â¢t live in an area where a chance is provided for them to take advantage of. The natural resources are just enough for them to get by. This is why the people of New Guinea produce so little ââ¬Å"cargoâ⬠of their own. Pizarroââ¬â¢s capture of Atahuallpa and destruction of the Incas made the Europeans realize what power they head, and what they could do to the rest of the world. They easily wiped out the Incaââ¬â¢s of 80,000 with 168 men. From the Battle of Cajamarca, Pizzaro came back to Charles I saying that Europe had the power to conquer the Americas. There were reasons Pizarro and the Europeans could conquer the Americasâ⬠¦ They had better warfare than the Incas. Pizarroââ¬â¢s men had armor rode horseback and used steel compared to their wooden weapons. Eurasia happened to have an abundance of edible material because of the right environment leading to the domestication of plants and animals led the people to settle down in one place instead of being nomads. When people started to settle down and bring the food to them, they started to have a surplus which led for the people to have extra jobs and it started to also support a higher population while allowing women to have more children contributing to job specialization. These specialists were not devoted to farmers or food producers but varied to priests, blacksmiths etc. Permanent agriculture societies were able to from with the food surpluses leading to empires. Some of the reason that people began to settle down and farm are because at the time many wild foods began to decrease due to hunters and gatherers killing off too many large animals leaving life unsustainable. More wild plants that could be domesticated became available at the time. Technological advances allowe3d people to harvest and store greater amounts of food that they cultivated. Human populations rose itââ¬â¢s not clear how much it caused food production and how much food production caused it but researchers believe thereââ¬â¢s a connection. As populations rose, they needed to have better food supplies and started farming. The farm societies were able to drive out neighboring hunter-gatherers. A continent with long east-west axis like (Eurasia) has an advantage over continents with long north-south axes (like Africa and the Americas). The reasons it does have to do with crops and longitude. In general similar crops can grow at similar longitudes. In other words a cropped that developed in one place can be spread east to west (or west to east) but less likely to spread north and south. Epidemic diseases developed among the societies that had been farming the longest. These were Eurasian societies. Societies in the Americas, Australia, and other places had not been farming as long and lacked epidemic diseases. When Europeans came in contact with Native Americans, for example, European epidemic diseases killed huge percentages of the Native Americans. This helped the Europeans conquer and the conquest made them richer and more powerful. Therefore germs help to answer Yalis question. The societies that did independently invent writing were those with complex hierarchies and sophisticated systems of food production. Writing was needed for politics and was generally learned by bureaucrats who had the comfort of available time and energy. As food was available to them, they had no need to hunt and gather for themselves. Since their basic needs were being met, they could focus on a higher level of existence and communication. There are two conditions in which technology may develop. The first is ââ¬Å"mother necessity ideologyâ⬠which is when a society needs something to make things easier they invent it. Technology differed from place to place because there were more people to invent and better diffusion to spread the invention. The opposite happened in the Americas because there were less people and a slower diffusion rate. Also different cultures had different ideas for change. The only way that society can emerge is through food. Such developments include jobs, such as the chief and the beginnings of government. The institutions of society changed over time based on how organized they were. They evolved based around various factors like war and other societies. They are related by diffusion. Whenever a state is conquered by another state they enforce use of their technology or exploit it. States are going to develop weapons, troops, and religion in order to make the state survive. They develop in response to need of their population size. They use these agents of conquest to become larger and to conquer other societies; and for that they need guns, germs, and steel. What Diamond is saying is that he thinks that people really should not think that history is so much different from the sciences. He is saying that the study of history can be pretty scientific if it is done correctly (and that some sciences are not as precise as things like chemistry). Diamond is trying to argue that historians should use what he calls natural experiments. He thinks that there are many experiments where there are two or more places that are pretty similar in many ways but which then turned out differently (like his experiment in Chapter 2). He argues that historians can use these they can look at what was different and what was similar and how the differences led to the differences in the outcomes. Guns, Germs, and Steel Book Review I think Diamondââ¬â¢s central intent of writing the book is to explain how varying societies become dominate, and how certain others can become dominated. By looking at environmental conditions that caused the disparities that lead to certain societies developing guns, germs, and steel, including other technology, and forming a government necessary for conquest. He introduced the book with Yaliââ¬â¢s question ââ¬Å"Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people has so little cargo of our own? â⬠This question used a scientific/geographic background, and set his intent is to answer the question or inform how to answer the question. He also tries to analyze the causes of the expansion of civilizationsââ¬â¢ in some parts of the world, since all people are physically the same what could cause some to be successful and others to die? He used archaeological and historical case studies and evidence from genetics and linguistics, he argued that technological and gaps in power are not caused by race or culture differences but by environmental differences, He used the idea of the axis as one saying that Eurasia had an east to west (or west to east) therefore having an advantage over Africa or the Americas for instance, because crops could grow at the same longitude but it was more difficult as they went north and south. Also when cultural or genetic differences have favored Eurasians like for example written language or resistance to epidemic diseases he says these advantages occurred because of the influence and geography on societies and cultures and were not inherited as genes from Eurasian ancestors. Diamonds book argues that the differences in progress for different societies around the world do not result from one group being smarter or more resourceful than another. Rather, he focuses on the impact of geography whether food and other key items were plentiful, whether and how disease spread, and how these developments led to different levels of industrialization, and wealth The book ââ¬Å"Guns, Germs, and Steelâ⬠was very well written in the sense that Diamond had a question in which was the foundation of the book, he throughout the book acquired evidence and explanations and ideas of how to answer the question. The book had evidence to back it up by explaining how Eurasia had a better opportunity being west to east meaning they had better crop farming. Which led to a growing civilization and soon conquest. The book wasnââ¬â¢t exactly dull or boring but it wasnââ¬â¢t exciting or entertaining either. It was like any other history book it asked a question, then went on to the point. There was an explanation of the main topic which was Yaliââ¬â¢s question and evidence that dealt with answering the question. From beginning to end, Diamond stresses that he realizes that efforts to compare societies have frequently been used by racists or nationalists to belittle groups or justify mistreatment of them. He argues that his analysis is in fact anti-racism at work because it shows that the white people who enjoy the comforts of modern life are ultimately luckier than, not more deserving than, people in impoverished nations.

Study Of Autocratic Leadership Style Management Essay
Study Of Autocratic Leadership Style Management Essay There are many ways to lead and every leader has his own style. Some of the most common styles include autocratic, bureaucratic, democratic and laissez-faire. Autocratic Leadership Style This is often considered the classical approach. It is one in which the manager retains as much power and decision-making authority as possible. The manager does not consult employees, nor are they allowed to give any input. Employees are expected to obey orders without receiving any explanations.Some studies say that organizations with many autocratic leaders have higher turnover and absenteeism than other organizations. These studies say that autocratic leaders: Rely on threats and punishment to influence employeesà à Do not believe the staffà à Do not allow for employee inputà à Nevertheless, the autocratic leadership is not so bad.Sometimes it is the most effective style to use.à Such situations may include:à à Employees do not respond to any other style of leadershipà à There are high volumes of production needs on a daily basisà à There is limited time for decisionà à Work must be coordinated with another department or organizationà autocratic leadership style should not be used in the following cases:à à Employees become tense, fearful, or resentfulà à Employees are expected to have their opinion heardà à Employees begin depending on their manager to have all their solutionsà à There is low employee morale, high turnover and absenteeism and work stoppages Bureaucratic Leadership Style Bureaucratic leadership where the manager manages by the book. All must be done in accordance with the procedure or policy. If this does not apply to books, the manager refers to the next level above him or her. This manager is really more police officers than the leader. He or sheà apply the rules.à This style can be effective if:à Employees perform routine tasks over and over again.à Employees must understand the specific standards or procedures.à Employees working with hazardous or fragile equipment that requires a set of procedures for the job.à Safety and security training is conducted.à Employees perform tasks that require cash handling.à This style does not be effective if:à Skills of the forms that are difficult to break, especially if they are no longer useful.à Employees are losing interest in their work and their colleagues.à Employees do only what is expected of them and nothing more. Democratic Leadership Style It encourages employees to be part of decision-making process.Democratic manager keeps his or her employees informed about everything that affects their work and shares decision making and problem-solving responsibilities.à Democratic leadership can produce high quality and quantity of work for long periods of time.à Many employees like the trust they receive and respond cooperation, team spirit and high morale.Typically, the democratic leader:à Develops plans to help employees assess their own performanceà Allows employees to set goalsà Encourages employees to grow jobs and encourageà Recognizes and encourages achievement.à Like other styles, the democratic style is not always appropriate.It is most successful when using highly skilled and experienced employees or when implementing operational changes or permits a person or group problems.à The democratic leadership style is most effective if:à The leader wants employees informed about matters that affect them.à The leader wants employees to participate in decision-making and problem-solving responsibilities.à There is a large and complex problem that requires a lot of input to solve.à you want to promote team building and participation.à Democratic leadership should not be used in the following cases:à There is not enough time to get the input of each.à Its easier and more cost effective for the manager to decide.à Business can not afford mistakes.à The manager feels threatened by this type of leadership. Laissez-Faire Leadership Style This kind leadership style is also known as hands-off à ¨ style. This is where the manager gives little direction and gives employees more freedom as possible. All authority or power is given to employees, and they must set goals, make decisions and solve problems independentlyà .à This is an effective style to use when:à Employees are highly skilled, experienced and educated.à Employees have pride in their work and desire to do it successfully yourself.à Reliable and experienced staff.à This style should not be used in the following cases:à It makes employees feel insecure in the absence of the manager.à The manager can not provide regular feedback to employees know how well they are doing.à The manager does not understand their responsibilities and hopes that staff can cover for him or her. P7. Explain the different motivational theories and their application within the workplace Maslows Hierarchy of Needs is the most widespread theory.à He believes that human beings have desires that influence their behavior in particular unmet needs.à needs come in order of importance.à person to the next level is necessary if low-level need is satisfied.à on the need to level the person moves, more personality and mental health reveals.à These requirements, from a lowest to highest are: psychological, health and safety, social, esteem and self-actualization.Examples of physiological needs are food and water.à Security refers to security, freedom from violence, safety, and others.Social is a sense of belonging as family, friends, colleagues and other professionals.à Self-esteem is a need for approval, recognition, status, etc.à And, finally, self-actualization refers to the need for personal growth through education, religion, hobbies, and others.à According to Maslow, it would be difficult to achieve the ultimate goal of self-realization, if the following goals are not met or taken care of first.à Food, water, shelter these are just some of our most pressing needs, which precede all others.à For example, it would be silly to worry about how to become emotionally stable, when you can not even have a decent meal or if you are seriously ill.à Taking care of immediate needs, you can begin to take care of the higher needs. Just as Maslows hierarchy of needs, Herzbergs Two Factor Theory is a need-based theory of motivation.à This theory is considered more powerful than Maslow, because it is easier to understand.à two-factor theory says that certain factors in the workplace leads to job satisfaction.à Others did not affect the satisfaction, but if not can lead to dissatisfactionà These factors of motivation and hygiene factors.à Motivators to ensure job satisfaction.à This includes the recognition, responsibilities and tasks.à Hygiene factors are so called because, like hygiene, their presence will not make people healthier, but their absence can cause decay.à Examples of these include salaries, fringe benefits, job security.à Hygiene factors, therefore, can determine dissatisfaction and motivators determine satisfaction. Both scales are independent and one can score high on both factors. Vrooms Expectancy Theory explains why people choose a certain course of action. Unlike the three aforementioned theories, Vrooms theory is not need-based. There are three variables in this theory: Valence, Expectancy and Instrumentality. Valence refers to the importance of the anticipated outcome of a situation. Expectancy is the belief that the effort exerted and success of the situation are related. Instrumentality means the success is related the expectations Vrooms Expectancy theory could sometimes be associated with work situation just like Herzbergs Two Factor Theory. But, in actuality, this theory is applicable to almost all kinds of situations whether work-related or not. Vrooms expectancy theory simply espoused the idea that the reason people do some things is because they expect a certain outcome. I apply Vrooms expectancy theory to my professional life because I believe in doing things not because I want to attain a certain reward but I want to attain something I truly desire for myself. For instance, I do a good job at the office not because I want a promotion, although it is part of it, but because I expect to feel fulfilled after having done something worthwhile. P8. The relationship between motivation theory and the practice of management: Different motivation theories have different effects. Motivation has to be built into the structure and without the motivational theory without the practice of management. You cannot practice motivation if you do not first have a theory or concept. In order to be a great manager or leader you have to be a good motivator, you should know what motivates your staff and what doesnt. A manager who cannot motivate or doesnt know how to motivate cannot do a good job, his job is to improve the performance of the staff and motivate all of them. P9. Describe the nature of groups and group behavior within organizations: Nature of groups The term group can be defined as, two or more persons interacting and working together to get a job or something done. When people work in groups rather than as individuals, the goals of the organization can be easily achieved. Groups can get a job done fast and usually accurate, group members could gather information and tell each other if they are doing something wrong or not, and they could appoint themselves to do a specific job which they are best in to contribute as much as possible to the group. People form groups for various reasons. Maybe get a job done faster or even to get a job done while not putting as much effort if youre the only one working on something. Various Types of Groups: There are formal and informal groups in organizations. Various groups exist within the organization and they are of varying degrees of formalization. Groups in organizations are of various types based on the number of members they have and the interactions between them. Formal Groups A group formed by the organization to accomplish a specific task is termed as a formal group. The organization sets up a formal group and allocates tasks and responsibilities to different members with the intention of achieving organizational goals. Command groups and task groups are examples of formal groups. A command group is relatively permanent in nature and finds representation in the organization chart. Functional departments of organizations are considered as command groups. Task groups, on the other hand, are formed for a specific task and are temporary in nature. They are dissolved after the task is accomplished. After dissolution of the task group, the members of the task group continue as members of their respective functional departments or command groups with reduced duties. Informal Groups Informal groups are formed by the employees themselves. The reasons for the formation of informal groups could be the need for companionship, common interests, growth, recreation, or support. There are two types of informal groups friendship groups and interest groups. Members of friendship groups have a cordial relationship with each other, common interests and are similar. They like each others company and want to spend time together. Interest groups are formed to organize an activity and are temporary in nature. Informal groups mainly satisfy the social needs of members. à à à à à à à à à à à With regards to nature of groups, I would just like to add that members may have conflicting ideas and having your views challenged should could either reaffirm your own beliefs or transcend them-people should come into groups with an open mind. P10. Investigate the Factors Lead to Effective Teamwork and Influences that Threaten Success: In todays workplace, the group leaders need to solve complicated problems and to take ideas from their first stage through a series of complex processes to a successful completion. This kind of work cannot be done alone. There are just too many demands, task requirements and various sources of information required to do it without the support of others. The most important factor that can lead to efficient teamwork is motivation, it is a team leaders job to delegate tasks and to make sure that each member of their team contributes and is good at what they do. For example, if Picasso was one of the members in your group then you should give him a task that requires creativity, since being creative and artistic is his strength then it seems that natural that hell be good at what hes assigned to do. Leaders should build a relationship with its members by making ideas together and supporting it, and even improving each others ideas. They must be open and approachable P11. Evaluate the impact of technology on team functioning within a given organization:à à à The use of new technologies can improve and in some cases hinder team functioning. As technology changes teams must update and maintain their knowledge in order to function effectively. Technologies which have improved team functions Computers Internet Email Cell Phones Blackberry Groupware PDA Personal computers allow team members to carry out various tasks and communicate more effectively. Laptop computers allow you to do this anywhere. They are now lighter, more powerful and a longer battery life. Personal Digital Assistants (PDA) now have much of the same functionality as laptops, but are smaller, more portable and have a longer battery life. Many PDAs now have wifi as standard and some are also phones (and some phones have many PDA features). Internet has been a huge, worldwide explosion in the use of the Internet. It is already changing the way we work, shop, bank etc. Information technology has had an impact on the way we work for quite some time, but the Internet has now added electronic mail (email), teleworking and video conferencing to the workplace. E-mail allows direct communication which means team members do not need to be in the same place at the the same time in order to communicate effectively. E-mail also has its negative aspects in terms of managing e-mail and the misuse of e-mail. Cell phones have come a long way since the 1980s and there are now more mobile phones in the UK then there are people. Mobile phones allow teams to communicate even when team members are out of the office, on the road or otherwise unavailable. Sometimes having always access to team members can hinder team functioning. Phone technologies such as blackberry and 3G datacards allow team members to work and communicate remotely. Groupware enables teams to plan meetings, collaborate, delegate all within a virtual environment which can often be accessed remotely from anywhere in the world. Technology is found in its various forms in small and large businesses, the service sector, and state institutions, manufacturing companies, educational departments, multi-national organizations and the local shop.
String Definition And Concatenation Of Strings
String Definition And Concatenation Of Strings For this mini group project, me and my partner have been given a project title to be discussed which is string definition, null string and length, concatenation of strings, substring, and also languages and natural languages. This topic is the subtopics from the main chapter 3 which is Sequences and String. From this chapter basically this chapter help student especially in the application of computer programming. In this era of information technology humans have been doing math and physics for a long time until now in such from the geometry and logic of the Greek era of the Mediterranean, the numeracy of the Hindus in India, and also the development of algebra by Islamic scholars in Baghdad, until to the explosion of knowledge and learning in Europe after the invention of movable type. In 1970s, the string theory was born. Three particle theorists have been independently realize that the dual theories developed in 1968 to describe the particle spectrum. The quantum mechanics of oscillating strings also have been described. Thus it marks the official birth of string theory. Moreover, string theory is the leading candidate theory of quantum gravity. In fact, there are several consistent variants and they all have the certain common features. The most obvious are the replacement of point particles by strings and the six extra curled-up space-time dimensions. Thus, due to their extra mathematical origin, these distinct string theories can admit very and various different mathematical descriptions. Besides that, from the research, it says that the string currently know it there is not much indication that string theory is discrete. Strings can be described as the continuous loops in space. But, there has been some interesting work by Susskind and others which does seem to suggest that string theory could be discrete. As for the early conclusion, string theory has produced derivations of mathematical theories like toric geometry and K-theory, and a host of string-motivated conjectures in virtually every field of mathematics. Whatever its the inevitability of string theory as a mathematical theory of the highest order is hard to dispute. In light of this, perhaps we should turn Wigners remark around and marvel instead at the unreasonable effectiveness of string theory in mathematics. INTRODUCTION OF THE RESEARCH All of mathematics, as well as subjects that rely on mathematics, such as computer science and engineering, always make use of functions, sequences and string and also relations. And nowadays, most modern computer programs are represented by finite sequences of characters. String definition From the book, it says that finite sequences of the form a1, a2, à ¢Ã¢â ¬Ã ¦, an are called strings. Strings are normally restricted to sequences composed of symbols drawn from a finite alphabet, and are often indexed from 0 or 1. A string is just a finite sequence where S is a set of characters. Strings denoted by putting the characters together, for the example 12345. Besides that, strings are the fundamental object of computer science. Everything discrete can be described as a string of characters. Decimal numbers: 1010230824879 Binary numbers: 011101010111 String Notation A string notation can be described as a string which is a finite sequence of 0 or more letters in some pre-set alphabet ÃŽà £. For example decimal numbers: ÃŽà £ ={0,1,2,3,4,5,6,7,8,9} and for binary numbers: ÃŽà £ = {0,1}. Null string and length The unique string with no elements is called null string, will represented the lambda symbol l . Its length is zero: |l| = 0. Besides that, null string also be known as empty string which the string with no elements. Either way, the length of a finite string is just its number of terms (or of distinct indices). The length |s| of a finite string s is its number of positions which is the number of index values i. Concatenation of strings, substring The operation which be known as concatenation which is concatenation of two strings and it is formed by joining two end-to-end. We can say that the concatenation of the strings book and case is the string bookcase. In discrete mathematics we often use the concatenation of two strings such as a and b which the operation on strings consisting of writing a and followed by b to produce a new string of ab. Next is the concatenation of two or more numbers is the number formed by concatenating their numerals. For example, the concatenation of 1, 234, and 5678 is 12345678. The value of the result depends on the numeric base, which is typically understood from the context. For substring, given a group G of order g, then let U denote the set of all ordered multi-sets of elements of G. This will let V denote the subset of U consisting of multi-sets with exactly g components, and let A denote the subset of V consisting of multi-sets of exactly g distinct components. Languages and natural languages In information technology (IT), especially in computer programming, we are sometimes required to process a language. So, basically from discrete mathematics we will learn the concept of languages in a systematic way. For example, a compiler is a software that can translate a computer program written in a particular language into another language which is usually into a machine language. While for natural language processing is a study of how to produce the computer software that is capable of understanding natural language. We start with the 26 characters A-Z, and string them to form a word. Thus, the language will consist of a collection of such words. RESULT OF THE RESEARCH STRING DEFINITION A string over X, which X is such a finite set that is a finite of a sequence of element X Let, X = {a, b, c} and then we let: a = ccabbb this is a string over X and than the string will be written notation ccabbb = c2ab3 String is a sequence and the order is taken. The example that can we see is the string given accbbb that is different from the string ccabbb even that has same value but it is still different because of the order. In internet (computer science) Let ÃŽà £ be an alphabet, a non-empty finite. A string over ÃŽà £ is any finite sequence of characters from ÃŽà £. For example; If ÃŽà £ = {0, 1}, then 0101 is a string over ÃŽà £ From both example given, we can see that in computer science also use, that it is same but just difference in using the symbol of X and ÃŽà £. NULL STRING The null string also known as empty set that is the string with no elements .It is denoted by letter l (lambda). It has length zero. We also denote X* is the set of all string over X and also denote X+ is the set of all non-null string over X. Let, X* = {all strings over X including l} Example1: Let X= {3, 4} Some elements in X* are: 44, 33, 43, 4433, 4, 3, 44034343, l Example2: Let X = {b, c} Some of element in X* are: c, b, bcbc, b40c4bc, l For X+ we Let X+ = X* {l}, the set of all non-null strings over X. LENGTH OF STRING The length of a string a is the number of elements of a and that it is denoted by |a|. If a = a2bc3 or aabccc then |a| = 6. If |yet|=3, |another|=7, |usage|=5, |pipe|=4, |symbol|=6. CONCATENATION OF STRING Concatenation of two strings a and b is the operation on strings consisting of writing a followed by b and it produce ab a = bbaccc and b = caaba, Then, ab = bbaccccaaba = b2ac4a2ba Clearly, |ab| = | a| + |b| In computer programming String concatenation is the operation of joining two end to end. Example: The strings beach and ball may be concatenated to give beachball. First example: The following expression use the + symbol as the concatenation operator to join 2 strings: Print hi, + dear; produces the concatenated string hi, dear by joining those 2 strings Second example, (wet+land) is equals to (wetland). It shows that concatenation can be achieved with the + string operator. LANGUAGE AND NATURAL LANGUAGE Let B = {2, 3};- The example is languages over B: L1 = {2, 23, 233, 2333,à ¢Ã¢â ¬Ã ¦} L2 = {2m3m | m > 0} L3 = {2m3n | m > 0, n > 0} Suppose that B is a set of alphabet. That it is define a language L over B is a collection of strings over X.A language L is simply a subset of A. CONCLUSIONS AND RECOMMENDATIONS As for the conclusions, this topic of sequence and string help both of us to think and link what we have learnt in the module of discrete mathematics within computer science and information technology. From this topic we have doing research about string definition, null string and length, concatenation of string, substring, languages and also natural languages. By doing this mini project we have investigated that the applications of this topic in discrete mathematics involve in the areas of computer science and IT. Nowadays, most modern computer program are represented by finite sequences of characters. We therefore need to develop the algebraic way such as string for handling such finite sequences. Moreover, this string topic is important to be learned by the student as it much involve in the application of computer programming. In computer programming, essentially, the string is a sequence of characters which is generally understood as a data type usually storing data values usually bytes. The elements usually stand for characters according to a character encoding, which will differentiates it from the other general array data type. Thus, the terms binary string and byte string are used to suggest strings in which the stored data does not necessarily represent text. While in discrete mathematics we learn string as mathematical structures. As we have doing our research on this topic, we can see that this topic involve much in the application of computer programming. As both of us are from science computer course, we can apply what we have learned in discrete mathematics into our application programming. Finally for the recommendations to improve more this topic which is Sequence and String, both of us have think that while in the lectures student should given more detail and explanation of string involving the subtopics of null string and non null string. Moreover, deep explanation about the function of language and natural languages in string also will help much the student to understand more this topic, apply it in the programming skills, and can do well in our final examination. The benefit of doing this mini project is both of can develop our understanding of the concepts and the applications of discrete mathematics through experiences which enable both us to explore more and model a variety or real-world situations. Special thanks to our lecturer Prof Dr. Haslina which have help both of us in giving the guidelines to do well for this our discrete mathematics mini project.

The Importance of Physical Fitness Essay -- Exploratory Essays Researc
The Importance of Physical Fitness Are you sick of gasping for air just after a quick trip up the stairs or feeling overly fatigued after a ten minute game of catch with your son? Maybe it is time you get busy and get in shape. What does it really mean to be physically fit? This is a question many of us ask ourselves when we set out to look better and feel better about ourselves. I personally don't know one person in this world that longs to be fat and out of shape. When you finally get off the couch, put the snacks back in the cupboard and decide it is time for you to get in shape, you usually head toward the gym first. Eating right and exercising are the two things that usually come to mind first in order to "get fit." There are however more than just a couple of things one must do to get in shape. Physical fitness is to the human body what fine-tuning is to an engine. It enables us to perform at our highest levels. Fitness can be described as a condition that helps us look, feel and do our best. More specifically, it is: "The ability to perform daily tasks vigorously and alertly, with energy left over for enjoying leisure-time activities and meeting emergency demands, and is a major basis for good health and well-being." ("Fitness...") Physical fitness involves the performance of the heart and lungs, and muscles of the body. And, since what we do with our bodies also affects what we can do with our minds, fitness somewhat influences qualities, such as mental alertness and emotional stability. ("Fitness...") As you undertake your fitness program, it's important to remember that fitness is an individual quality that varies from person to person. It is influenced by age, sex, heredity, personal habits, exercise and ... ...sition has never been a great measurement of sports performance. Lean muscle mass seems to be related to the performance in sports where the ability to generate maximal force is required. Good body compostion is essential for health. In order to achieve good body composition one must eat right and exercise to the best of their ability. (Quinn) Hopefully after learning a little bit more about physical fitness and what it takes to accomplish it, you can go play with you son or daughter and maybe have a little fun while doing it. Without all that wheezing to make it up the stairs you can get more done during your day and still have energy left over for yourself. I hope this information can help you get a jump start on your new exercise program. Don't forget to use all five of the components. These will help you with every aspect of your program to become more fit.

Revenue Determination: Pricing and Contracting Essays -- Business Reve
Over the last twenty years health care prices for the general public, because of this continuous rise in prices hospitals and health care facilities have given much attention to improving their communication of prices to the public. Most people of the general public are unaware that hospital costs and hospital prices are two different things. Hospital cost is the dollar amount the hospital pays in order to provide patient care. Hospital price is the dollar amount designated to the specific procedures performed in order to provide said ââ¬Å"patient careâ⬠. This dollar amount is what the hospital bills the insurance company and/or the patient for their care (Cleverly & Cameron 2007). It is important for health care facilities and hospitals alike to provide a sense of reasonableness within their bills so that their patrons do not get the feeling that they are being ââ¬Å"ripped offâ⬠. Many people feel that the reason their health care bills are so high is because hospital s feel they can charge whatever they want for a product people have to have. In general, sick people will not turn down a life saving treatment because it is too expensive, because the health care industry is aware of this, they charge whatever price they can get away with, like charging the patientââ¬â¢s insurance three times the base price (Cleverly & Cameron 2007). What the general public always seems to overlook is the fact that even hospitals need to turn a profit in order to keep their doors open and keep providing genuinely good health care to their patients. There are three generic factors that influence the way any firm, including health care facilities influence their pricing. These three factors are, the desired net income of the firm, the firmââ¬â¢s competitive positio... ...They are held to ââ¬Å"reasonableness of chargesâ⬠and it is important that the public knows the facts before speaking out against their local hospital. Health care costs money, therefore like any business hospitals must charge for their services, plain and simple. Works Cited Devers, K, Casalino, L, Rudell, L, Stoddard, J, Brewster, L, & Lake, T.

Fiber Optics :: essays research papers
Fiber Optics Assignment Many modern medical materials and equipment work on a principle which is beyond the capacity of human transducers. Comment and discuss the working principles of an endoscope, uteroscope or a rectoscope showing the illuminating path, the image path, transmission path and the liquid transfer or operating instrument ducts, showing the position of suitable valves. This will therefore explain how light travels through an optical fibre and show how such fibres are used in medicinal equipment either to transmit light or to bring back images from within a patient. Contents Fibre Optics Fibre-Optic Bundles Coherent and Incoherent Bundles à à à à à Transimission efficiency and resolution à à à à à Types of Fibres: Single mode or Multimode ? à à à à à Fibre Properties Fibre-Optic Endoscopy à à à à à Introduction à à à à à The Fibre-Optic Endoscope à à à à à Some Applications for Fibre-Optic Endoscopy References Fibre Optics A relatively new technology with vast potential importance, fibre optics, is the channelled transmission of light through hair-thin glass fibres. The clear advantages of fibre optics are too often obscured by concerns that may have been valid during the pioneering days of fibre, but that have since been answered by technical advances. Fibre is fragile An optical fibre has greater tensile strength than copper or steel fibres of the same diameter. It is flexible, bends easily, and resists most corrosive elements that attack copper cable. Optical cables can withstand pulling forces of more than 150 pounds. Fibre is hard to work with This myth derives from the early days of fibre optic connectors. Early connectors where difficult to apply; they came with many small parts that could tax even the nimble fingered. They needed epoxy, curing, cleaving and polishing. On top of that, the technologies of epoxy, curing, cleaving and polishing were still evolving. Today, connectors have fewer parts, the procedures for termination are well understood, and the craftsperson is aided by polishing machines and curing ovens to make the job faster and easier. Even better, epoxyless connectors eliminate the need for the messy and time- consuming application of epoxy. Polishing is an increasingly simple, straightforward process. Pre-terminated cable assemblies also speed installation and reduce a once (but no longer) labour-intensive process. Fibre Optic Bundles If light enters the end of a solid glass rod so that the light transmitted into the rod strikes the side of the rod at an angle O, exceeding the critical angle, then total internal reflection occurs. The light continues to be internally reflected back and forth in its passage along the rod, and it emerges from the other end with very little loss of intensity. This is the principle in fibre optics of which long glass fibres of very small cross-sectional area transmit light from end to end, even when bent, without much loss of light through their side walls.

Zurich, May 2007 Hirokazu Sugiyama Abstract In recent years, chemical a core companies have adopted the concept of sustainable development as business value. The basis of various decision-making in their entire business has been extended to cover aspects, especially non-monetary issues, the in addition to economic performance. sustainability This thesis From the viewpoint of chemical engineering, big challenge is to integrate criteria early a in process design for as design objectives. rocess presents framework of chemical design, whi ch incorporates multi objective consideration economic, and environmental, health and safety (EHS) different aspects in decision-making over design stages. With a focus on the early design according phase, to four stages, Process Chemistry as a I/II and Conceptual Design I/II, modeling are defined the available information basis for process and assessment. For each defined to economy, stage, appropriate modeling methods and evaluation indicators with respect lifethe cycle environmental impacts, EHS hazard and technical aspects are selected. Based at on evaluation esults, multi objective decision-making is performed systematically the each stage. A case study on methyl methacrylate (MMA) production study, which processes is applied throughout routes this thesis. This case uniquely offers 17 potential synthesis and various types of chemicals in the reaction network, is applied for demonstrating the framework. Starting with 17 an possible synthesis routes, optimized inferior routes are eliminated step-by-step and at is the last stage flowsheet of the route with the best multi objective case performance produced. observing Another part of the the evaluation study alidates decisions made within the framework over by profile of six routes when different stages. Most routes are correctly selected at earlier routes. cause design stages are compared are to the detailed assessment results of all six Several factors identified that to available in detail only at later stages, and which significant updates the results. Among these are the magnitude of energy consumption, EHS investment cost, the amount of loss of valuable of materials, and the monetary and a implications newly considered substances. For these parameters there is measures need to have better estimates in the form of proxy lready at earlier stages. Two what-if analyses are presented to examine how the assessment results are change when the different process options or evaluation settings considered. One ana lysis investigates l impact of specifying process options at the detailed conceptual design stage, i. e. the rigorous flowsheeting stage, economy and and the effect of choosing different setups in evaluation for the criteria of The MMA case life-cycle environmental impacts. options study quantitatively reveals that, among different types of process and evaluation settings, specifying alternatives in reaction chemistry, e. . synthesis path, has the most significant impact. This result confirms the importance layouts of reliable proxy indicators for for different forecasting unknown aspects, e. g. detailed process synthesis paths, in early design stages. the As the second part of the assessment what-if analysis, Several and impact of method selection can on the EHS results is presented. simple methods that The be applied in the early phases are compared qualitatively on quantitatively. assessment results change significantly depending The overall the hazard evaluation method in the ap plied in each of the EHS aspects. scope, iscrepancy mathematical result stems from the differences in the manner considered mass parameters, formulation, and especially own that process no information is treated. However, each method has its merit of one background and there is unique or method a over the other in any of the EHS aspects. The appropriate simplicity can degree only of detail of method considering early design phases where it be applied is the characteristic that separates the methods. Finally, the developed framework is serves as represented by using a a standardized activity modeling use technique, IDEFO, enables the which of blueprint f the business model.

Stems Cells And Regenerative Dentistry Health And Social Care Essay
With make up kiosk therapy scientists hope to bring around maladys and exchange change wanders and variety meats in the adult male electric organic structure. ascendant kiosk query for the possible finishing of jail cell form therapy in dental consonant consonant euphony has incited a considerable sum of exhilaration. At subject teeths can merely be re sayd with naturalized prosthetic device such as removable or mawed alveolar consonant prosthetic device and implants. Some initial success utilizing dental composition cells in vitro every bit adept as in vivo remedy being a priori accounts promises a sensible hereafter for the therapeutic system of basis cells in regenerative dental medication 1 . In my f either uponings I select explored two types of merciful subside cells in relation to regenerative dental medicinal drug. They ar military man being dental decide cells and bring forth Pluripotent stalk Cells ( iPSCs ) . The intent of my r esearch was to find what patch up cells atomic number 18 and its place in regenerative dental medicine.Keywords Regenerative dental medicine, weave paper technology, gouge cells, dental descent cells, induced pluripotent conciliate cells. hold cellsThere ar soon three types of benignant result cells apply in bio health check research, Human Embryonic Stem Cells ( hESCs ) , bounteous ( material ) Stem Cells and bring forth Pluripotent Stem cells ( iPSCs ) . Stem cells argon un specialized cells constitute in the organic structure that ready rise to specialized cells of a specialised tissue type. They can split and self-re virgin-fangled for indistinct periods throughout the life-time of an being. They atomic number 18 capable of a centrosymmetric division into farther root cells and symmetrical division into committed primogenitor cells. They argon classified harmonizing to their possible to accredit which is totipotent, pluripotent and multipotent. In the ea rly phases of human maturement, the fertilised egg cognise as the Zygote is considered to be totipotent ( Latin totus significance all-inclusive and potens intending origin ) . It has the possible to stop rise to an full being including the extra-embryonic tissue of the placenta and umbilical cord. During the blastodermic vessicle phase of embryogenesis, the cells found in the internal cell mass ar know as Embryonic Stem Cells ( ESC s ) . ESC s are capable of full-grown rise to all three sources beds in the human organic structure and are later responsible for coevals of all tissues and variety meats, excepting extra-embryonic tissues. ESC s are considered pluripotent ( Latin plurimus intending really many an(prenominal), potens intending power ) . Adult ( Somatic ) Stem Cells ( ASCs ) are theoretically hand in every type of tissue, found in a root cell niche 1, 9 . In grownups, root cells serve as an internal fix system to refill and replace damaged cells in tissues an d variety meats. Bodily Stem cells are somewhat more specialized than ESCs as they can largely fare into the cell types of the tissue in which they reside. ASCs are hence considered multipotent. Due to rapid immature finds in Stem Cell Science, scientists comport introduced a third type of human root cells known as generate Pluripotent Stem cells ( iPSCs ) . IPSCs are bodily cells that are genetically manipulated to presume an embryologic root cell like province. They express the pluripotence potency of embryologic root cells. This fortunately circumvents honest issues environing the usage of ESC s, therefore progressing the pertinence of root cells in regenerative medical specialty 4, 5 . estimate 1Diagram project ESCs, which through immunosurgery is derived from a 3-5 two dozen hours preimplantation embryo known as a blastodermic vessicleTissue technology and DentistryTissue technology is the interdisciplinary field of medical pattern that applies the rules of biomedical scientific prepare to reparative medical specialty. In regenerative dental medicine, two types of tissue technology train been described. The first is conventional tissue technology for re- formation of dental tissue utilizing mesenchymal cells in vitro. The 2nd is whole tooth regeneration utilizing mesenchymal cells and dental epithelial tissue in vivo 1 . The footing of whole dentition or single dental tissue regeneration is dependent on the acquirement of suited root cells and suited environmental conditions.Figure 2Diagram picturing the construct of utilizing a tissue technology attack to make new flesh tissue and let for tip of the perpendicular and sidelong root formation in a immature tooth that had mush mortification induced by speck 2 .Stem cells in clinical dental medicineIn order to control the pertinence of root cells in regenerative dental medicine, a dismiss timidity of the procedures of embryogenesis and odontogenesis ( tooth development ) is indispensable. The cells have-to doe with in odontogenesis are of ectomesenchymal beginning. During embryogenesis, the nervous crest cells arising from the exoderm of the nervous tubing and mesenchymal cells arising from paraxial mesoblast move to organize the adorn organ and dental papilla. The enamel organ is the lone organ of epithelial beginning involved in odontogenesis. All other constructions of a tooth are of mesenchymal beginning. During odontogenesis distinction occurs through cell communicating. This is through with(p) via signalling molecules and growing factors. A tooth has two anatomic parts the Crown covered with enamel exposed in the oral endocarp and the root which is embedded in the jaw. about the tooth the periodontic ligament attaches the cementum to the difficult bed sheet of the alveolar bone 1, 2 . hypertext transmit communications protocol //www.jopdentonline.org/na101/home/literatum/publisher/ vizor/journals/ heart/odnt/2006/15592863-31.6/06-000/production/ima ges/large/i1559-2863-31-6-633-f05.jpegFigure 3 2 hypertext transfer protocol //www.jopdentonline.org/na101/home/literatum/publisher/pinnacle/journals/content/odnt/2006/15592863-31.6/06-000/production/images/medium/i1559-2863-31-6-633-f01.jpgDiagram picturing the molecular signaling XT mingled with 2 cells dental Stem cellsThe tissues of a tooth are enamel, dentin, cementum and mush. With the exclusion of the ameloblasts progenitor cells which get together rise to enamel, all root cells involved in odontogenesis are of mesenchymal beginning.Dental root cells are bodily root cells. learning on human embryologic alveolar consonant root cells is non yet in stock(predicate) 1 . Dental mush root cells ( DPSCs ) can be derived from dental mush. Dental mush can be obtained from tertiary grinders or pulpectomised dentitions. In odontogenesis dental follicle plays a major function in the development of cementum, periodontic ligament and alveolar bone. Dental follicle root cells ( DFS Cs ) can be obtained from wedged 3rd grinders. Periodontic Ligament root cells ( pdlSCs ) can be derived from the roots of extracted dentitions. PDL which suspends the tooth in its send out sac contains stem cells that can give rise to cementum and ligament. Stem cells from the top(prenominal) portion of the papilla ( SCAPs ) are precursors of the dental mush. SCAPs are gettable from wedged 3rd grinders. Stem cells from human broadleaf dentitions ( SHEDs ) can liberal be obtained from the coronal mush of exfoliated deciduous dentitions. The easy handiness of mesenchymal dental root cells makes them a suited campaigner for cell based therapies in dental medicine. Their naughty proliferative capacity and potency to distinguish into cementoblasts, odontoblasts, PDL primogenitors, bone-forming cells and assorted other cells implicated in odontogenesis, promises a prospective hereafter for dental root cells in clinical dental medicine. Soon the application of root cells in clinical dental medicine is hindered by many roadblocks such as awry(p) eruption of dentitions, morphology of the generated tooth and most importantly the current impossibleness of renewing human dental enamel 1 .Human Induced Pluripotent Stem Cells ( iPSCs ) and orodental illnesssApart from ethical quandary that have long surrounded the derivation of human ESC s from developing embryos, its immunoincompatability for usage in developing disease-specific iPSC lines in vitro from patients has besides keep its application in regenerative medical specialty. through and through coincident overexpression of certain cistrons, iPSC lines can be produced in vitro utilizing assorted human cells. afterwards derivation, iPSCs undergo word picture techniques and teratoma checks. victorious iPSC lines can be equated to hESC s in proliferative and developmental possible 4, 5, 10, 11 .The new-fangled promotions in IPS engineering have brought its application to the head of biomedical research. P reviously iPSC s were genetically manipulated through the usage of viruses and episomal vectors for genomic integrating. This methodological analysis proved inefficient. Since so new methods have been introduced to deduce iPSC s unacquainted(p) of vector and transgene DNA. With the usage of man-made courier RNA to bring on pluripotency and distinction, scientists are able to accomplish cellular reprogramming by pull stringsing the whole genome system preferably than a little set of passkey cistrons. When biochemically coaxed, iPSC lines are able to distinguish into cell types of assorted diseases. The ability to animate disease specific root cells from givers, whose genome is present, makes disease patterning more dependable. This allows for a improve apprehension of the pathogeneses of diseases and its variableness amongst patients. The ability to carry on drug proving on human disease-models lead besides progress the efficaciousness of perniciousness trials and farther drug d evelopment. Some disease-specific iPSC lines have already provided a deeper apprehension of disease complexness and mechanisms. The possibility of utilizing iPSCs to handle orodental diseases could be a powerful curative apparatus in clinical dental medicine 4, 5 .DecisionThe usage of root cells in regenerative dental medicine is still in its pre-clinical stage as at that place many hurdlings yet to get the better of. The current impossibleness of renewing ameloblasts primogenitor cells to bring forth enamel is amongst the many obstructions impeding whole tooth regeneration. However, the possibility of shake up autologous dental primogenitor cells and tissues in vitro holds a promising hereafter for alveolar consonant cell based therapies. The usage of IPS engineering in dental medicine is a new construct, although its application in making disease specific lines and haply reprogramming familial orodental diseases will surely scratch the hereafter of clinical dental medicine. The successful usage of root cell scientific discipline in regenerative dental medicine will surely guarantee that the twenty-first century tooth doctor plays a sarcastic function in the field of regenerative medical specialty 4 .Methods of researchThe literature used to carry on this research was obtained from medical checkup Journal Publishing websites. This included PubMed and the subject field Institutes of Health. Additional beginnings included correspondence from the theatre director of the International Centre for Genetic engineering science and Biotechnology ( ICGEB ) , every bit good as a Postgraduate disciple in Developmental Biology. For instruction and a deeper apprehension of Cell biological science, DNA, chromosomes and viruses to understand root cell scientific discipline the Khan Academy was used.
