Domestic Violence and Developmental Psychology Essay
Domestic Violence and Developmental Psychology - Essay Example The Centre for Children & Families in the Justice System of the London Family Court Clinic Inc has published several research studies about domestic violence that take into account the perspectives of developmental psychology as a working framework. Baker, Jaffe, Ashbourne, and Carter published "An Early Childhood Educator's Handbook" with the title of "Children Exponed to Domestic Violence". Cunningham and Baker published a comprehensive study entitled "What About Me Seeking to Understand a Child's View on Violence in the Family". These works are very helpful to deal with the issue of domestic violence from the point of view of developmental psychology since they take a humanistic psychology standpoint. It is important to note that humanistic psychology emerged in the 1950's as the "third force" in Psychology (Association for Humanistic Psychology, 2001; Van Wagner, 2008b). The "first force" was behavioral psychology, and the "second force" was psychoanalysis. Now the "fourth force" seems to be transpersonal psychology or spiritual psychology (Institute of Transpersonal Psychology, 2003). But the research studies by the London Family Court Clinic Inc mentioned above take a humanistic psychology standpoint when they undertake their developmental psychology approach on domestic violence. ... The name Humanistic Psychology was finally chosen to acknowledge indebtedness both to classical humanism of ancient Greece and to the great humanist scholars of the Renaissance. Humanistic psychology rejected the medical sickness model and embraced a growth and emancipation model of healing. These ideas were echoed in the radical psychiatry of R. D. Laing and the anti-psychiatry movements of David Cooper in the U.K., Thomas Szaz in the U.S.A., and Franco Basaglia in Italy." (2005, p. 2). In this sense, the point is to deal with psychology from the point of view of health, not of illness. On the other hand, developmental psychology is described in the following terms by Van Wagner: "Development describes the growth of humans throughout the lifespan, from conception to death. The scientific study of human development seeks to understand and explain how and why people change throughout life. This includes all aspects of human growth, including physical, emotional, intellectual, social, perceptual, and personality development. () The scientific study of development is important not only to psychology, but also to sociology, education, and health care. Development does not just involve the biological and physical aspects of growth, but also the cognitive and social aspects associated with development throughout life." (2008a) (See also Hola.co.uk, 2006). The main issues of developmental psychology are enumerated as follows by Van Wagner: "Nature vs. Nurture () "Early Experience vs. Later Experience () "Continuity vs. Discontinuity () "Abnormal Behavior vs. Individual Differences (2008a). On the issue of domestic violence, the following terms are explained by Baker, Jaffe, Ashbourne, and Carter: "Domestic violence

Policy Suggestions for Reopening Dual Language Essay Example for Free
Policy Suggestions for Reopening Dual Language Essay This empirical research will be presented to the Ministry of Education in Taiwan for the purpose of studying the possibility of reopening Chinese and English dual language kindergarten schools.            In 2004, the Ministry of Education in Taiwan had forbidden the operation and establishment of bilingual and English kindergarten schools. English could only be integrated in songs, plays, and activities but it could not be taught in the Chinese and English bilingual format and use as a medium of instruction. Kindergarten schools are not also allowed to hire any foreign teachers. All kindergarten teachers must be a natural born Taiwanese citizen.            In the same year, the spokesman of the Ministry of Education cited three reasons for implementing this educational policy. First, they feel that at the preschool stage children should master their primary language. Second, they are so concern with the quality of teaching as they found out that most foreign teachers who worked as English teachers in kindergarten schools do not have sufficient knowledge on early childhood education. These teachers are only hired because they are native English speakers. Third, although Taiwanese students officially begin learning English on the third grade, they do not lag behind their counterpart in other Asian countries. However, there is not enough research to prove the positive effect of banning the dual language kindergarten. The research cited by the Ministry of Education to support their policy is discussed in the review of literature. Review of Related Literature Research Supporting the Policy            The research used by the Ministry of Education of Taiwan as a basis in supporting its policy was conducted in 2001 by Dr. Chuang Shiang Chuan and    Dr. Chaing Jen Ru. These professionals were invited to conduct a study on the possibility of integrating English in the kindergarten curriculum and hiring foreign teachers to teach in the kindergarten level. In this research, Dr. Chuang Shiang Chuan pointed out that language learning for children requires the use of both the expressive and thinking abilities. If the medium of instruction is strictly in English alone, the content of communication between the teacher and the students would be very limited. She also indicated that preschool children fail to accurately pronounce and comprehend a foreign language in comparison to the adult learners. Furthermore, she also stated that learning a foreign language could interfere in the learning of the mother tongue. In terms of hiring foreign teachers, Cheung (2001) felt that foreigners who are working as kindergarten English teachers do not have the required skills and knowledge on early childhood education. Their knowledge is only limited to the teaching of the English language. In addition, hiring of foreign teachers would result in the decrease of job opportunities for students who have completed their education degrees from the teacher preparation institutions. However, the findings of       Dr. Cheung may not be objective and conflict of interest is evident as a result of her employment in one of the early childhood teacher preparation institutions. Besides, in the policy statement published by the Ministry of Education to the public on October 10, 2004, it was stated that the research was based on the neuroscience, linguistics and English education findings which indicated that learning English at an early age does not guarantee that children will learn better. The Ministry of Education also argued that teenagers learn a foreign language more efficiently than preschool children due to their more mature cognitive development. It is also stated that imposing the â€Å"No Chinese†kindergarten education would result in communication difficulty, emotional disturbance, conflict of values and problems in culture identity which could affect the development of Chinese language learning. Furthermore, the language barrier would limit the breath and dept of children’s learning.            Lu Chen (2003) who are researchers in Taiwan also supported the previous findings and argued that it is inappropriate for preschool children to learn a foreign language and culture at an early age. They believed that China would be the strongest country in terms of economic stability and the Chinese language would be the next universal language. Hence, parents should not be anxious to have their children learn English at a young age. They further stated that there is no critical period in learning a second language so it is not necessary to start learning at preschool age. The researchers also believed that having a good command of the native language is the foundation for learning a second language. The absence of an American or British accent is not an important matter to consider in learning the English language. Therefore, it is unnecessary to study English at an early age to avoid speaking with a foreign accent.            Besides the two researchers and one government statement above, the book â€Å"My Child Can’t Speak Chinese†(Cheung, 2004) is also frequently cited by people who are against using English as the only medium of instruction in the kindergarten education. In this book, Cheung depicted her daughter who tends to combine the English and Chinese syntaxes when speaking Chinese after attending an English only kindergarten school. In the book, the arguments to ban the English only teaching in kindergarten school is understandable considering that children in Taiwan speak Chinese at home and kindergarten is the first education that they have experienced outside their homes. The use of English as the only medium of instruction in their first school may give the children the wrong impression that English is the formal school language. They may also think that their Chinese language is less important. These thoughts could possibly lead to the confusion of culture identity and negatively affect the learning of the Chinese language.            As an international student who had studied in various classes with native English instructors and have worked as the sole foreign teacher in an American school, I understand the anxiety that a child may feel in an English only environment based on my personal experience.            Armed with a first hand experience in obtaining an education in an English only school under instructors who are native speakers of the English language and with an experience of being a foreign teacher in an international school, I can strongly understand and clearly see the point in the policy made in not allowing the operation of the English only kindergarten schools. However, in as much as I could empathized with the policy makers, I also felt the inadequacy of the study that was conducted before arriving at a recommendation to close and prohibit the existence of dual language kindergarten schools. There are many dual language kindergartens in the United States and I have taught in an English-Chinese dual lingual public school in New York, P.S. 184M, Shuang Wen School. This is the first dual lingual and bicultural public elementary school in the east coast. Children at Shuang Wen have regular English classes as other public school students and start learning Chinese from the kindergarten level and continue studying until the sixth grade.            In the Shuang Wen’s website, there is a report cited that almost 100% of their students exceeded the required grade level standards of the New York State examination for Math and English. With Shuang Wen’s success, one could only ponder as to why American students are allowed to enroll in an English and Chinese bilingual program since kindergarten while the Taiwanese students in Taiwan have to be deprived of this opportunity. I went through literature reviews by searching and reviewing dual language related literatures on databases of ERIC, ProQuest, Education Full Text, Digital Dissertations taken from the Teachers College as well as the TC Catalog (EDUCAT). The summary of my findings are written below. Research on Dual Lingual Education            The dual lingual education literature reviewed is presented here in the following sections: bilingual education has no harm, the benefits of bilingual education, the best bilingual education-dual language program, and the current situation of dual language programs. Bilingual Education Has No Harm            Contrary to the findings of the researchers in Taiwan, Norbert (2005), Schambach (2006), Garcia (2006), and Pearson (2007) claimed that bilingual education has no harm to children at all. All the misconceptions were bias. For instance, Cheung’s (2003) worry concerning her daughter’s combined usage of English and Chinese is actually unnecessary. The combined usage of language was part of a learning process that children want to experiment in order to determine which of these two languages the listener’s â€Å"strongest language†is. This method would also enable the children to communicate effectively with their listener (Garcia, 2007). Moreover, the capability of switching between two languages could increase children’s cognitive flexibility (Steward, 2004). In terms of the concerns about the lost of identity and delay in the development of the children’s first language, it was discovered that bilingual children do not have any identity issues because in the bilingual education, children’s culture are respected and recognized (Farmer, 1998 Schambach, 2006). Some children may develop two identities since they are educated in using two languages and two cultures but this helps children to be more adaptable to the global world and prepare them better to be global citizens. Moreover, Schambach pointed out an example of an identity issue whereby an immigrant child, who emigrated from one country to another, felt totally lost when not being accepted in the new country and treated as a foreigner upon return to the country of origin for a short visit. This situation can happen to Taiwanese children if the government is not open to the education that the parents expect for their children in Taiwan. About 77% of parents in Taiwan hope that the government would allow the integration of English in the kindergarten curriculum (Wu Cheng, 2002). The main reason for the immigration to the United States of Taiwanese families is to provide better education for their children. If Taiwanese government fails to meet parents’ expectations, there is a strong possibility that Taiwanese family immigration would lead to a problem on the identity issue for the next generation. The Benefits of Bilingual Education     After clarifying that bilingual education creates no harm to children, many researchers pointed out that bilingual education can enhance the development of children’s cognitive and social skills (Chan, 2003; Garcia, 2007; Norbert, 2005; Steward, 2004; Thomas, 2003). Chan (2003) compared 31 bilingual preschoolers and 29 monolingual preschoolers’ performance on 3 cognitive tasks and 4 theory-of-mind tasks. The results showed that the advantage of the bilingual learners in the theory-of-mind development hinges mostly in their cognitive development e.g., inhibitory control, reasoning and metalinguistic awareness. Garcia (2007) quoted the research of Peal and Lambert’s work with French and English bilinguals and English monolinguals and suggested that the intellectual experience of acquiring two languages contributed advantageously to mental flexibility, superior concept formation and a generally diversified set of mental abilities. She also cited Padilla’s reasoning that bilinguals are cognitively advanced because they are able to process information provided in one language and produce allied information in another language. Padilla used Keats and Keats’ report of a study as an example which German-English bilinguals, who did not demonstrate the ability to conserve weight in a Piagetian task, were trained to conserve in one of the two languages. Results from English and German post tests indicated that the concept was acquired in both languages. This suggests the possible increased in the flexibility of bilinguals during conceptual acquisition. Steward (2004) cited the finding of Willig who pointed out that students in the bilingual programs scored either the same or higher on the achievement tests in both languages in comparison with children in monolingual education. Steward also agreed with Cummings, Hakuta and Gold’s opinion that the bilingual program has increased children’s cognitive flexibility. Thomas (2003) further stated that the cognitive stimulus from the bilingual program led to enhanced creativity and analytical thinking. He also presented the result taken from Houston in 2002 that native English speakers, who had been in the two way dual-language programs for four years, scored between 63rd and 70th percentiles in total reading scores in the Stanford 9 whereas the scores of students in the monolingual English program hovered around the 50th percentile. This is a remarkable finding that could be used to infer that if Taiwanese children, who are native Chinese speakers, are educated in a bilingual program since preschool their intellectual capability might surpass students in a Chinese only program after four years. After reading all the benefits that bilingual education can bring to students, I continued to research for the definition of bilingual education and its best practice. The Best Bilingual Education Dual Language Education            Barrera (2004) defines bilingual education as using two languages to learn. Schambach (2006) said a bilingual person means he can use two languages freely in any given situation. In terms of the best practice for bilingual education, Garcia (2007) pointed out that in teaching two languages, it would be best to separate them instead of combining them together. For example, at home each parent should speak a different language to the child and at school, different teachers should speak different languages. Children tend to learn the language in order to communicate. Norbert (2005) further strengthened the importance of separating two languages when teaching. Scofield (2007) specifically talked about the importance of a relaxed environment that is enriched with comprehensible language as well as the usage of gestures, mime, and real objects to illustrate speech and to provide input. He also suggested singing songs and rhymes and having group activities to create a conducive environment for the learners. In terms of time allocation for teaching each language, Steward (2004) cited Willig’s research result which showed that students in the alternate immersion program, wherein the day is divided into two halves each entirely in one language, have the best performance in the tests of both languages. This kind of program is also called dual language program. Current Situation of Dual Language Education            According to Barrera (2004), there are more than 270 dual language programs in the U.S. and the interest in these programs keeps growing as fast as the waiting lists. In Barrera’s research, she concluded that the most successful dual language program resulted when students learn one language in the morning and another one in the afternoon. There must also be a continuing non-repetitive lesson in the morning. In the succeeding morning, students must proceed to the next lesson in the other language. The important characteristics of a good dual language program as suggested by Barrera includes: a minimum of six years instruction; a focus on the core academic curriculum; high quality language arts instruction in both languages; integration of the languages into the instructional thematic units; separations of the two languages for instruction with no translation and no repeated lessons in the other language; use of each language in 50 percent of the instructional time; an addictive e.g. adding a new language at no cost to students’ first language; bilingual environment that has the full support of school administrators, teachers and parents; and an active parent-school partnerships.            However, regardless of all the benefits of dual lingual education as shown in the research, some politicians in California still think that English should be the one and only dominated language in United States. Hence, they brought up Proposition 227 to replace the bilingual and dual lingual education to total immersion method to help immigrant children learn English as fast as possible. Nevertheless, many researchers discovered that bilingual education has helped children learn English faster than the total immersion method (Krashen, 2005; Manyak, 2006; Monzo, 2005; Olson, 2007). Bilingual education has likewise helped students build more positive self identity by providing a sheltered learning environment (Monzo). Recommendation            After learning from the studies conducted by some researchers, the Taiwanese government must reexamine their educational policy that resulted in the total ban of bilingual kindergarten education in Taiwan. I recommend that the Taiwanese government conduct an empirical study on the possible effects of dual language kindergarten education in Taiwan and recruit volunteer participants to determine if the Chinese and English bilingual kindergarten education should be reopened as an educational option for Taiwanese children.            I would also like to suggest a research design which includes the preparation of the curriculum, teachers’ preparation, students’ selections and students’ evaluation. Curriculum            Prior to conducting a research, the Education Ministry of Taiwan must initially design a Chinese and English dual lingual curriculum for kindergarten pupils. The easiest and most efficient way is to translate the current kindergarten curriculum into English. In this method, the traditional Taiwanese values are neither changed nor altered and the English language was only used as a medium of instruction. This consistent and continuing curriculum, which is part of the current dual language program, has been proven to be the most beneficial way for students’ learning. Teacher Preparation            Secondly, the government must prepare all the teachers who will be involved in teaching the dual language program. The selection of teachers who would teach the Chinese curriculum is not as difficult as selecting teachers who could teach the English curriculum. For the Chinese curriculum, experienced teachers can be selected among a roster of kindergarten teachers. Since the current law forbids the hiring of non-Taiwanese citizens, it would not be easy to immediately hire English instructors. There may be few Taiwanese people who could teach using the English fluently, have a solid background in early childhood education and fully understand the Taiwanese culture. Since learning the language while keeping the Taiwanese cultural background are two major purposes of the dual language program, I would suggest to the Ministry of Education in Taiwan to hire Taiwanese Americans or Taiwanese people who have studied abroad for a long enough period of time and have attained a good level of English fluency. The qualification to become a kindergarten teacher in Taiwan should not be based on the nationality but on the teacher’s English capability and understanding of Taiwanese culture. With regards to having a solid knowledge on the background of kindergarten education, I believe that teachers can be prepared within few months of extensive workshops as I became a primary teacher at an award winning independent primary school in Connecticut after a week of intensive training and continuing professional development throughout the school year. In my job, I performed well as a foreign teacher. Through experience, I personally felt that it is possible to prepare any teacher for the background knowledge. Further research on this issue could be conducted to be assured that only the most qualified teachers are selected for the program. Students’ Selection and Follow-Up Plan            Participating pupils should be voluntary and the opportunity to be a participant should be well broadcasted to all the parents who have children who are about to be enrolled in kindergarten schools. Students should be chosen from families of a mixed social economic status to represent the common student population in public kindergarten schools. Plans must be undertaken for students who are currently attending kindergarten so a continuing dual lingual elementary education can be achieved until the fifth grade as suggested by Garcia. Garcia discovered that the positive effects of dual language education will be manifested after 6 years of continuous education. The greatest challenge here is that all dual lingual elementary schools in Taiwan are private schools and therefore the tuition fees are not affordable by every family. For this problem, the government could either give vouchers or subsidize the tuition fees of the children who have attended the dual lingual kindergarten so they could study in private dual lingual elementary schools. In addition, the government can also put an effort to open a public dual language elementary school in each grade level to accommodate the education needs of these students. Data Analysis            Students’ cognitive development and academic performance will be assessed through standardized testing and observation from teachers and parents. Data analysis will focus on the findings to determine if advance cognitive development and better academic performance were achieved by students who were given the dual language program in comparison with the dual language students’ performance in the United States and Canada as studied by Barrera (2004) and Chan (2004). To avoid overstressing students, the test will be carefully designed and will be taken semi-annually. Likewise, students’ progress will be recorded for six years. Conclusions            Education is the best investment for the future of a country. With the influx of globalization and stiff economic and business competition, it is time for people of Taiwan to be armed with an education that could be comparable not only to their neighboring Asian countries but also to the western countries as well.            The progress of the country highly depends on its young citizens and the best way for the young citizens to be competitive is by providing them with an educational tool that will enable them to communicate with other people across the globe. English has been considered as the universal language in many parts of the world. There are no negative effects in learning a foreign language as shown in many research studies. Hence, it is time for the government of Taiwan, specifically the Ministry of Education, to study their policies and reconsider the option of reopening bilingual kindergarten schools in Taiwan. If the government intends to be the educational leader in Asia, it is time to open their doors to accept the teaching of English in preschool level. References Barrera, R., et. al. (2004).

The Democratic Symbol Essay -- Politics Government Symbolism Essays
The Democratic Symbol The word â€Å"donkey†has come to have a negative connotation in today’s society. In Webster’s Handy College Dictionary, the definition for a donkey is â€Å"an ass†or â€Å"a stupid or obstinate person†. One would presume that with such a meaning, the Democratic Party, one of the main political parties in the United States, would not be associating itself with such a negative symbol. The first use of the â€Å"donkey†as the Democratic symbol occurred during Andrew Jackson’s run for president in 1828. Because of his populist views and the slogan, â€Å"Let the people rule†, his opponents tried to label him as a â€Å"jackass†, but Jackson used the name-calling and turned it into his advantage by placing the donkey on his campaign posters (The Democratic). Since its first application in 1828 the â€Å"donkey†is a symbol that is now clearly associated with the Democratic Party. This association is present because the attributes that complement this symbol are some of the many attributes that characterize and define the Democratic Party. Although the masses might view the â€Å"donkey†as a representation of something stupid, or silly, the Democratic Party, on the other hand, has come to view the â€Å"donkey†as a symbol that stands for intelligence, courage, and humility (The Democratic). One of many important characteristics that define the Democratic Party is its member’s ability to solve issues that affects the party or the nation in an intelligent manner. This ability came into play on October 29, 1929, at the start of the Great Depression (â€Å"New Deal†). The inherent instability of the market brought about the Great Depression in 1929, and to resolve this instability, government intervention was necessary t... ...eal.†Wikipedia. 22 Nov. 2004. .

Qualifying Saunt’s “Great Transformation†with a Broader Perspective of Indigenous History :: Essays Papers
Qualifying Saunt’s â€Å"Great Transformation†with a Broader Perspective of Indigenous History As the new American nation emerged in 1783, freshly baptized in the blood of war and swollen with patriotic pride, the transformative ideology of materialistic monism slipped soundly into the heart of the Creek Nation in the Deep South and never let go. Saunt tells us this was a novel cultural metamorphosis. Subverted indigenous ethnocide, over 50 years in the making, now found with the advent of the war sweeping economic accommodations in capitalistic competition. Western vehicles of individualistic profit and cultural prestige freely flourished among the southern Indians; the African slave trade boomed among the Creeks, young warriors bartered for rum instead of sustainable grain, and mestizos acquired valuable connections through war efforts and bribes. Yet while this change pervaded Creek society with unprecedented vigor, what evidence exists to prove this shift the most noteworthy in Indian life and memory? While the cultural wounds of these few notable decades are carefully and proudly recorded, and are indeed transformative times, they exist as a mere moment over the course of four centuries in the living testimony of Western cultures transforming and shaping Native American History. However, I contend that Saunt’s â€Å"great transformation†of Creek materialism in Revolutionary America is undeniably significant, especially in his claims linking prestigious mestizos, like Colbert and McGiverlly, to dual forces of ethnocide and environmental destruction in their co-optation with European authorities. Tumultuous and aggressive, colonialism in the late 18 th century promoted a new ideology within the very heart of Deep South. The vital inner structures of clan ties and community tasks were essentially eradicated with the â€Å"great transformation†of Creek culture. Ancient traditions of clan and the martial ties that once â€Å"created a dense network of interrelationships throughout the deep South†were lost in the Revolutionary war politics (Saunt 21). Factionalized and dissident peoples stumbled along in the absence of common compassion. Where trade and marriage were once â€Å"indissoluble†and essential to establishing formidable allies and friends, individualistic pursuits of material gain and power assumed the helm. Even existing agreements with European colonies which previously â€Å"demanded that allies exchange gifts rather than commodities†became secreted, deceptive exchanges of poor quality skins for rum (43). Saunt is correct is assessing the broad ripple effect of this possession plague: European trade monopoly forcibly ripped apart the fabric of Indian society. Rum was more tempting than household goods required by women in caring for their clan, and when young warriors exchanged heaps of ill-prepared skins for an intoxicating drink, they had to resort to plundering necessary clan goods from surrounding communities.

The President’s National Drug Control Strategy
The National Drug Control Strategy was announced by the Bush administration during the first quarter of 2002. It is believed that the strategy was devised because of the perceived loss of â€Å"the national will to fight against substance abuse. †This perception resulted from a dismal situation recently occurring in the country. For instance, the findings of the â€Å"Monitoring the Future Survey†which was conducted by the University of Michigan showed that 26 out of 100 eight grade pupils admitted to trying illegal drugs at one time or another. In addition to this sad reality, it was observed that many drug dependents in the United States do not get the treatment required to help them get rid of their addiction. Faced with such a grim state of affairs, President Bush declared his belief that â€Å"the time has come to re-energize the national movement against illegal drugs †¦[by making up] lost ground in the fight against drugs by applying the lessons of our recent history – emphasizing a balance between supply and demand reduction effort†(U. S. Office of the Press Secretary, 2002). It is clear, therefore, that the President’s intention is not only to reduce the use of illegal drugs in the country by reducing the number of drug dependents, but also to trim down the supply of drugs entering the country. To achieve this twofold objective, the strategy was based on the following principles, namely: â€Å"stopping drug use before it starts; healing America’s drug users; and disrupting the mark et†(U. S. Office of the Press Secretary, 2002). The strategy maintains that in the struggle against illegal substances, every citizen has a vital role to play in â€Å"stopping drug use before it starts. †This could be undertaken through education as well as community-wide efforts. Specifically, the strategy emphasizes that everybody should be an advocate for responsible citizenship. In other words, wherever he or she is, e. g. in the home, in schools, in his or her church, or in the place where he or she works, a standard should be set to reaffirm this value. In this connection, every individual should do everything to convince everybody to reject the idea that the decision to use illegal drugs is an individual freedom. In the home, the parents are expected to instill in the minds of their children that illegal drugs is evil and would destroy them and their future. The educators should also teach the same value in schools while church authorities are counted on to preach the devastating effects of drugs (U. S. Office of the Press Secretary, 2002). To backstop the efforts of schools and the community, the Office of the President granted an additional $10 million to expand the operations of the â€Å"Drug-Free Communities Support Program†of the Office of National Drug Control Policy (ONDCP), aside from creating a â€Å"Parents Drug Corps†with a budget of $5 million (U. S. Office of the Press Secretary, 2002). In addition, increased funding were also provided to other ONDCP projects, namely: $25 million to the drug testing of students for the year 2003 (a whopping increase of $23 million); $145 million to the anti-drug information efforts of the â€Å"National Youth Anti-Drug Media Campaign†for its 2005 expansion which would â€Å"include information for teens and parents to promote early intervention against drug use. †The media campaigns are aimed at changing the beliefs prevailing among American teenagers concerning drugs. Meanwhile, the ONDCP said that the additional $10 million budget for the â€Å"Drug-Free Communities Program†would be able to finance an additional 100 community coalitions who would work for the prevention of drug abuse among young Americans, especially in depressed areas of the country (U. S. Office of National Drug Control Policy, 2004). The strategy also aims to â€Å"heal America’s drug users. †To accomplish this goal, the budget for the â€Å"Substance Abuse and Mental Health Services Administration (SAMHSA)†for the year 2003 was set at $2. 35 billion, increasing it to $2. 49 billion for 2004, and $2. 4 billion for the year 2005. Of particular interest is the increase of more than $100 million in the 2005 budget of the SAMHSAâ€â€Access to Recovery (ATR) program. According to the ONDCP, this will provide financial assistance to drug dependents who wish to avail of â€Å"clinical treatment or recovery services†on a case-to-case basis (U. S. Office of National Drug Control Policy, 2004). Extending additional assistance to drug dependents would be complemented with the creation of â€Å"a new climate of ‘compassionate coercion’†to get drug abusers to enter the government’s treatment programs. Compassionate coercion would be carried out with the help of the criminal justice system and the circle of family and friends of the drug abusers. According to the President’s strategy, it is now time to â€Å"confront drug use – and therefore drug users – honestly and directly†and every effort should be exerted to urge abusers to â€Å"enter and remain in drug treatment†(U. S. Office of the Press Secretary, 2002). The drug courts program of the Office of Justice Programs was likewise granted an increase of $32 million from its 2004 budget, raising its 2005 funding to $70. million. According to the strategy, this funding increase would improve the chances of success of the drug court programs by widening the scope as well as increasing the quality of the services provided by drug courts. The strategy explained that the drug court programs are serving as alternative solutions to imprisonment which utilizes the â€Å"coercive power of the court to force abstinence and alter [the] behavior†of drug dependents (U. S. Office of National Drug Control Policy, 2004). In other words, under the strategy, the criminal justice system is interested more in treating and rehabilitating drug abusers rather than putting them behind bars. To further enhance the capability of the criminal justice system in the task of treating and rehabilitating drug abusers, the President’s National Drug Control Strategy also increased the budget of the National Institute on Drug Abuse (NIDA) from $960. 9 million in 2003 to $990. 8 million for 2004 and more than $1 billion for the year 2005. NIDA is the agency which is tasked with conducting research activities concerning the problem, specifically â€Å"on the nature of addiction, development of science-based behavior interventions, medications development, and the rapid translation of research findings into practice. †This initiative clearly spells out one of the most important roles of law enforcement in the drug policy of the president: that of treating and rehabilitating drug dependents (U. S. Office of National Drug Control Policy, 2004). Another, equally important role being played by law enforcement in the drug strategy of the president is that of â€Å"disrupting the market and attacking the economic basis of the drug trade,†thereby reducing, if not entirely eliminating, the supply of illegal substance available in or entering the country. For this purpose, at least six government agencies were enlisted, namely: the â€Å"Drug Enforcement Administration (DEA); the Organized Crime Drug Enforcement Task Forces (OCDETF); the Immigration and Customs Enforcement; and the Department of State†(U. S. Office of National Drug Control Policy, 2004). â€Å"Disrupting the market†means that law enforcement agencies have both domestic and international missions. In the domestic scene, they are tasked not only with arresting drug suppliers and rounding up drug abusers, but also with intensifying the security of our borders to make the entry of drugs more difficult. In the international level, law enforcers are directed to seek out and destroy the supply of drugs in the countries of origin like Colombia, Venezuela, Bolivia, and other countries (U. S. Office of the Press Secretary, 2002). The strategy considers reducing or eliminating the supply to be of paramount importance because less supply would mean that the substance would become more expensive and thus less available to Americans. For this reason, law enforcement agencies has been focusing not only on the â€Å"agricultural sources†of these illegal substances but also on their organizational set-ups, the transportation systems of suppliers and distributors, their â€Å"financing mechanisms†and their processing methods. Adequate knowledge of these things would enable American law enforcement agencies to destroy the drugs at source and easily intercept those that producers are able to ship out of their bases of operations (U. S. Office of National Drug Control Policy, 2004). The President’s National Drug Control Strategy should be regarded with respect not only because of its awareness of the importance of treating and rehabilitating drug abusers but also because it has correctly pointed out that the complete elimination of the sources of illegal substances is one of the keys to the elimination of the drug problem in the country. The effectiveness of the strategy could be measured in terms of the reduction in the number of drug users and dependents in the country and the reduction or elimination of the supply of illegal substances in the market. Reducing the number of users without eliminating the supply of illegal substances would never be effective since new users and abusers would always crop up.

All but one have been major layout redesigns (eg. , indoor seating, drive thru, play areas, self-service kiosks, etc. ). Adding breakfast foods to the menu (in the 80? s) was the one product change–until now. The front page article in The Wall Street Journal (Dec. 27,2010) details two brand new strategies–the 1st a product decision and the 2nd yet another layout change. Under pressure from market-share competitors of all types–from 7-Eleven and Starbucks to smoothie outlets and gas stations– the 14,000 US McDonald’s have broadened their fare. As of now, there are  fruit smoothies, oatmeal, carmel-mocha drinks, flatbread sandwiches, and â€Å"garden†snack wraps. This new product development strategy (Ch. 5) has created so many choices that the company has been running ads reminding us it still sells Big Macs. Using manufacturing technology, McDonald’s has made many new items from existing items’ ingredients. Chicken wraps use Chicken Selects’ meat and breakfast burrito tortillas. This simplifies preparation and lowers costs. But new layout costs have blunted franchisee enthusiasm. The food assembly line (see Figure 9. 12 in the text) had to be changed to make wraps. And an even bigger modification was the addition of the $100,000 McCafe drink stations– one of the most expensive changes in years. (The corporation picks up $30,000 of that cost). Stores had to be redesigned to make room for space next to the pick-up window to accommodate the 4 pieces of drink equipment. Some franchisees balked at the price tag and low drink sales volumes, claiming â€Å"we are not even paying for the electricity to run the machines†. Discussion questions: 1. Why did McDonald’s make these two strategic changes? 2. Ask your students to rank the importance of the 9 changes, referring to the Global Profile in Ch. 9. 3. How has the average McDonald’s changed in the past decades? Are all of the layout strategies still in place? OM in the News: Product Enhancement and the McDonald’s Happy MealJuly 27, 2011 tags: Ch. 5, Happy Meals, McDonalds, product enhancement y Barry Render Under pressure from 550 health organizations to stop marketing â€Å"junk food† to children and to retire Ronald McDonald (the clown mascot), McDonald’s has chosen the path of product enhancement (Ch. 5) as a preemptive strike. The New York Times (July 27, 2011) reports today that the firm will start to fill its Happy Meal boxes with apple slices and smaller portions of french fries this September. By next April, the new menu will be rolled out to all 14,000 restaurants. The food industry overall has come under increased scrutiny as childhood obesity levels have risen. San Francisco last year banned the inclusion of toys in kids’ meals unless there is a fruit and vegetable included. New York City has a similar rule in the works. Instead of developing all new kids’ products (or including vegetables), McDonald’s is responding with 1/2 the number of fries and a 20% lower calorie count. The new Happy Meal, containing 4 chicken nuggets and a small Coke, weighs in at 410 calories (vs. 520 in the older product), 17 grams of fat (vs. 23 g), and 58 grams of carbs (vs. 69 g). The firm decided against making apples a total replacement for fries when only 11% of customers showed an interest in that option. While some critics praised the changes (Mrs. Obama called them â€Å"positive steps†), one NYU prof called the move a â€Å"sham†, in part because McDonald’s is not limiting sodas. In fact, sugar levels go up with the Coke and apple together. Discussion questions: 1. What are the operations challenges in changing the Happy Meal? 2. Do students believe legislation is an appropriate means to make menus healthier? 3. How are other restaurants responding with children’s menu options. Mc DonaldsOne of the most important strategic decisions made by a company like McDonalds is where to locate their operations. Location options include maintaining current sites while adding another facility elsewhere. (Heizer, 2001)  Their facilities are located all over the world due to their franchising system. In the early 1990s, McDonalds began working with major oil companies to pioneer a new format for developing a restaurant, convenience store and fueling facilities on a single site. By co-developing sites, fueling facility operators and McDonalds could offer the busy consumer the ultimate in convenience ? one stop shopping for great food, branded fuel and convenience store items. According to Operations Management, McDonalds has revolutionized the restaurant industry by inventing the limited-menu fast-food restaurant. Some innovations it has made are the introductions of indoor seating and drive-through windows, which were strategic issues of facility layout. By adding breakfasts to the Is this Essay helpful?

McDonalds continues to improve their operations by innovating a new layout to facilitate a mass customization process. Some of the restaurants now have the Made for You kitchen system, where sandwiches are assembled to order and production levels are controlled by computers. This new layout is intended to both improve the taste of food by ensuring that it is always freshly made, and to facilitate the introduction of new products. Total production process time was shortened and other adjustments were made to save even more time and to work in conjunction with the new layout. This new layout will be more efficient, and save more time and money. It achieves a higher utilization of space, equipment, and people. A process strategy that may apply to McDonalds is a repetitive process. They moved from process focus to repetitive focus.

However, backtracking is to be avoided in whatever pattern is chosen. * Materials handling: It is essential to ensure the facility layout makes possible to handle materials (products, equipment, containers, etc. ).

Usa and Middle East, Heirs to a Millenium of Missteps
Usa and Middle East, Heirs to a Millenium of Missteps The USA and the Middle East experience a relationship today that bears the stamp of a millennium and more of crucial decisions on both sides.Advertising We will write a custom research paper sample on Usa and Middle East, Heirs to a Millenium of Missteps specifically for you for only $16.05 $11/page Learn More From nearly the first years of contact between people of European descent and the peoples of the Middle East, these decisions have reflected more misunderstanding and self-interest than statesmanship or vision. There are several moments over this span of time that stand out as opportunities: periods in history when relations could have been turned towards tolerance and even cooperation, but were not. Three examples of these are: the medieval push to take control of religiously important sites in what is today Israel, the betrayal of the region at the end of World War I, and more recently, the failure of Arab governments to adopt the best practices of m odern governance. While these are by no means exhaustive, they are exemplary. In the 11th century, the hardline, and an altered attitude of the Seljukian Turks towards Christian pilgrims prompted outrage and ill-organized crusades. However, a glance at a map of the area suggests the great potential advantage to the nations north of the Mediterranean of control over the sea lanes in the Mediterranean and eastward. Trade, at the least, would be easier if European powers controlled this region. This may have been the reason for the increasing emphasis on naval campaigns in the later Crusades (Bridges 10). In this instance, a more tolerant attitude by the Seljukian Muslims towards Christian pilgrims who had moved with relative freedom through the region for a long time would have made a great difference. After all, the Muslim faith had already successfully, albeit violently, taken over as much as two thirds of the European continent (Madden, Hillenbrand and Ryan). However, the behavior of the Europeans was regarded as boorish and ignorant by the Saracens, so there was probably fault on both sides (Madden, Hillenbrand and Ryan). This was a chance for mutual understanding that was thrown away. At the end of World War, after taking advantage of the Arab revolt to topple the Ottoman Empire, the Allies secretly agreed to partition the area. The Balfour agreement, also secret, promised the Jewish people a homeland in Palestine. These baldly self-interested betrayals and subterfuges were the reasons that prompted T.E. Lawrence to work for three years to make the Arab revolt as effective as possible (Lawrence).Advertising Looking for research paper on international relations? Let's see if we can help you! Get your first paper with 15% OFF Learn More This double-dealing gave the Middle Eastern countries a very good reason to resent the Allies (Lawrence). It also injected a massive and persistent disruptor into the area in the form of the Zionist hom eland (Zakaria, Why do They Hate Us?) . This dishonesty was probably not necessary and fairer dealings could have laid the groundwork for greater cooperation. Over the decades since then, the sponsorship by the USA of Israel has colored all US-Middle Eastern relations. More recently, the increasing interests of the European countries and the United States in regional oil have distorted matters further (Djerejian) (Atiemo). The Middle Eastern countries have not achieved the development of modern governments and what the West regards as desirable liberties and markets. To some degree, this retarding of governmental evolution was enhanced by the use of several countries as proxies for the former USSR (Djerejian) (Ahmadov). Many of the countries of the Middle East have, additionally, cut themselves off from many of the advantages of the Western world, often, according because of a distaste for the values associated with them (Ozdemir) (Christie, Zwarun and Clark) (Woods). It is possible that if the West had not been more honest and less self-interested, these nations might have turned towards Europe rather than to the USSR or to fundamentalism. Thus, the West and the Middle East may have had chances for rapprochement, which have been discarded. As far back as the Middle Ages, and in both the Twentieth and Twenty-first centuries, approaches have been taken that plunged increasing wedges of distrust and distaste between the two. These turning points should be our guide to avoiding such bad choices in the future. Ahmadov, Ramin. The U.S. Policy toward Middle East in the Post-Cold War Era.

How To Update All Social Networks At Once With CoSchedule
How To Update All Social Networks At Once With Does this sound like your experience with social media management so far? Youve been logging in and out of multiple social media accounts. Youve been posting the same message on all of them (and trying to do it all at the same time). And youve been getting mediocre engagement despite tons of effort. But you know there has to be a better way. Right? After all, that process ^ isnt very sustainable or efficient. Youre looking for: An efficient + effective way to manage all of your social networks in one place because getting organized makes you feel (and look) like a marketing rock star. And that way needs to help you not only update all social networks at once, but help you post well beyond now to build engagement consistently with an easy process (and without the constant hassle youre working through now). So lets explore the best way to find your app that can manage and update all your social networks in one place, shall we? How To Update All Social Networks At Once (+ Organize *Every* Account)1. Pick Your Social Networks + Accounts You may already post to several social networks. Thats great! This step is about building a social media accounts list to help you understand what youre doing well now, while also understanding the social media engagement opportunities youre not currently taking advantage of. Depending on your company, you likely have both business accounts and personal accounts. Heres an overview of the accounts you could manage with an all-in-one-social media app: Consider this a checklist for you to explore: Could any of these options present an opportunity for you to better reach your audience? Business Social Media Accounts: [ ] Instagram account [ ] Facebook page [ ] Facebook groups [ ] LinkedIn company profile [ ] Twitter handles [ ] Pinterest profile [ ] Google+ page Personal Social Media Accounts: [ ] Instagram account [ ] Facebook profile [ ] Facebook group [ ] LinkedIn profile [ ] Twitter handles [ ] Tumblr blog [ ] Pinterest profile The point of looking into your social media accounts list is to strategically choose the networks and accounts you can easily manage in an all-in-one social media app. It turns out, is an app that posts to all social media. As a social media marketing calendar, helps you not only update all social media in one place, it enables you to update all social networks at once (and long after posting just right now). As you use that checklist to decide what networks and accounts youd like to manage, just keep in mind that you can easily organize your posting process for all of them with . :) Easily organize your posting process for every social network with .2. Manage Social Networks In One Place Now that you know what accounts youd like to manage, its time to choose your app to manage multiple social networks in one place. For the sake of example, lets say youve chosen as your social media calendar. You made a good choice! ;) Its time to integrate your social media accounts into the one tool. Dont worry, its a simple process: Log in to the social network + account youd like to manage with . Cruise over to your Settings in and select Social Profiles. Connect your social account as a Public Social Profile (so your team can manage the messages for the account) or Personal Social Profile (so only you see the messages for your account). ^ Its seriously that easy. 3. Write Messages For Each Social Media Account When you update all social networks at once, youre posting to multiple accounts at the same time. This practice can be particularly useful when you share brand new content like blog posts, webinar landing pages, or have a strategic announcement from your brand. In these instances, its a best practice to change up your message for each account. This helps you optimize your messaging for the different networks while keeping the folks who follow you on multiple social networks happy + engaged. This way, you dont come off as blasting one message across all of your social networks (which comes off as a lazy social media engagement play). So whats the best way to do this? Start by writing one message for each specific account, optimizing your message for the specific network: Then, create + optimize a visual (image, graphic, GIF, or video) for each of your messages for the specific networks: You can use the Social Templates + Helpers features to easily organize the message creation and scheduling process in . First, start a new Social Template. A Social Template helps you create a posting schedule for all of your accounts that you can easily reuse over and over again to easily schedule dozens of social media messages in a matter of minutes. From here, you will create Social Helpers, then add those Social Helpers into a posting schedule template. There are Social Helpers for text, images, and videos. Start by naming your Social Helpers after the specific social media accounts they will match up with. Remember, youre building a reusable template at this point, so you can think of this like building form fields you will later fill in with the actual message creative for a specific campaign. Once youve added a text helper and image/video helper for each of your accounts, you can then build those as a posting schedule template. Save that Social Template, and then apply it in a piece of content, blog post, or social campaign on your social media calendar. Now you can fill in the creative for each social media message for your specific accounts once, apply your Social Template, and know your messages will send when you publish your content. You can see in this example that youll update all of your social media accounts at once, complete with unique messages optimized to increase engagement on every network. 4. Schedule All Social Networks In One Place When you update all social networks at once, its still possible that your followers who werent online at that specific time wont see your messages. Thats why its common for marketers to schedule messages and post to all social media long after the initial campaign. When youve written multiple messages to post to all social media, its efficient to reuse your hard work as part of a social media schedule to share your message a week, two weeks, a month, and sometimes even longer well after you post your first messages. ^ There are two great ways to reuse your messages efficiently with . Did you know you can reuse social messages efficiently with @?Way #1: Automate Your Evergreen Social Media Messages After you post your social media messages, will show you the messages that get the most engagement.

Dust storms Research Paper Example | Topics and Well Written Essays - 1250 words
Dust storms - Research Paper Example On the other hand, global warming is also playing a vital role in heating up the world terrain to a high extent through deforestation and discharging of industrial elements, where the climate and the environment has come under a major catastrophe. The environmental hazards and the natural disasters have covered the whole world along with the entire populace, civilizations and ecosystems with its drastic effects, that includes â€Å"dust storms, windstorms, sea storms, tornadoes, earthquakes, flood, volcanic eruption, cyclone, tsunami, and many more†(Webster, pp. 358). Dust storm is a meteorological event that comes under definition as â€Å"A severe windstorm that sweeps clouds of dust across an extensive area, especially in an arid region†(Webster, pp. 358). In other words, a storm that carries clouds, which comes under formation by dust through a very powerful unsettled and destructive wind, travels numerous miles in a region that tends to be dry and infertile. P arched and warm air comes under frequent alliance with the sand storm that is obvious and noticeable by massive pressures. A dust storm varies through their volume and the larger storm may engross and occupy pace of the particles that depend upon the wind haulage. One of the biggest calamities of dust storm that came under the experience by the inhabitants of United States occurred in the decade of 1930s, which brought mammoth corrosion to the soils and farms, and caused material hardships as well that made a big faction of the population to relinquish their homes. The blending and amalgamation of environmental aspects with human activities results in the happenings of dust storms. In general, the storm leave drastic affects on to the people as it breach and create obstruction in the air, road, and rail transportation, which compel the denizens to go in the house in order to get protection from the dangerous dusty air. These storms have such a strong impact that often, people come u nder coercion to depart from their residence and go through the course of sand and grime came with the storm. The strong dust cloud welcomes the natives who are outside due to work or other reasons and they experience the consequences of the storm (Heinrichs, pp. 4-9). The contributions of two factors that include the transfer of coarse that is flat and parallel; bits and pieces of dust sized; and the fluctuation of excellent minute elements that is upright makes up the course of action of the sand release and discharge. The small elements come under emission into the air in the form of nano-elements that erodes from the coarse elements such as the face of water bodies, where it comes under interruption by the hauling of meteorological turmoil that can be for thousands of miles. The impact of the dismissal or ejections of dust particles are significant on the marines and the output or the yield of world as they endow and enrich the environmental supplements and food.

Fiber optic is reliable with networking. I mean” how is it been Essay
Fiber optic is reliable with networking. I mean†how is it been secure†- Essay Example In a relatively short amount of time, a vast number of households and companies shifting from cable wires to this technological option. So just what makes this piece of technology so indispensable today? In a study from the Sans Institute Reading Room site, it says that fiber optic cables "can go an average of 62 miles versus 1.2 miles that copper can go before the signal needs to be regenerated or boosted." (Witcher, â€Å"Option 1†¦Ã¢â‚¬ ) Fiber optic cables also do not conduct electricity, since they are not metallic, which makes them less interfered by radio frequencies, electromagnetic interferences, or even lightning. They are also smaller and lighter than copper wires, and are not affected by atmospheric conditions making them even more "installation-friendly" to areas that copper wires cannot go. With all these, plus the fact that fiber optic cables do not produce electrical radiation, fiber optics has been the choice solution for a better and a more secure means of communication by companies across the globe. However, it is not all good news. Through the years, research has proven that fiber optic cables can be easily tapped. One, which is the easiest, is called splicing. Splicing is done by an inserted apparatus intercepting a signal while it is currently transmitting data to an end party. However, this method is easily detectable by most network security systems. Another method of getting data from fiber optic cables is through splitters and couplers. This method is done by slightly bending, crooking or putting a clamp on an optical fibers length so that light photons will leak into the tappers receiving device. Lastly, there are the non-touch methods. The more advanced of these methods are able to derive the underlying optical signal by understanding the interactions between the fiber plant and the extra light added into it. Without any physical-layer optical signal protection,
Three Gorges Dam- Tourism Venue and Creation and Loss of Jobs Research Paper
Three Gorges Dam- Tourism Venue and Creation and Loss of Jobs - Research Paper Example The business opportunities will provide a platform through which many people can establish some businesses in the area. For example, as tourists come to visit the site, it is apparent that they would require having some hotels and restaurants around and within the location. In this regard, people will venture into the hotel business thus creating jobs to many people. In order to have tourism facilitate effectively, there is need to have tourist operators who will organize and take tourists to the site. This way, many people will have an opportunity to work in these tour companies (Jim Para. 6). However, in the effort to relocate towns and people living around this area, it means that many people will loose their agricultural land and this could lead to lose of livelihood to these people (Yardley Para 50). People who relied on agriculture as their economic activity will loose it. It is apparent that the towns that will be relocated will lead to lose of jobs to many people. In these towns, many businesses will be destabilized and this leads to lose of jobs to both the owners and people employed to work in those businesses. After completion of the three Georges dam project, visitors will be able to see a wonder in the Yangtze River where a calm lake sits among the steep gorges. Many scenic spots which could not have been entered are now reachable. For example, in Fangyang River, the branch of Madu River, a new site of small gorges comes into view (Agencies Para. 3). The white Emperor city, which was originally hidden in the thick forest before, becomes an attractive island standing in the center of the River. This big scenery will attract more visitors to explore three Gorges (Backenheimer Para. 1). Since tourist will require having access to the site, it therefore means that they need to have means of transport to the area. In this regard, the construction of three Georges dam will largely improve the

Definition of the Feel Good Company Essay Example | Topics and Well Written Essays - 2000 words
Definition of the Feel Good Company - Essay Example Feel Good addresses the need for variety and flexibility. The Company has been performing well because it has sold a million bottles of its products every month in the year 2007. This kind of performance is relatively good indicating that the company's market share is on a steady rise. The market for soft drinks is cross generational and surpasses most age groups. However more emphasis is placed on the younger generation because they are the ones who are keen on new products and easily embrace emerging trends. (Jefkins, 1994) The company offers a range of chilled juices and fizzled drinks. The market is segmented into groups of people who take their meals at different times of the day. There are the lunchbox and breakfast markets. The Company's main competitors are the well established names in the fizzled drinks sector. These are companies like Coca Cola and Pepsi. This means that the company has to compete against the strong brand image that Coca Cola has established. This company is also characterised by strong captivating advertisements and promotions. Pepsi is also acclaimed for its reputable brand image. Feel Good Drinks also has to compete against other companies that produce chilled juices. These include Tropicana and Minute companies. Some of the brands which Feel Good has introduced that compete against the latter mentioned companies include Tangerine, Mandarin and Apple; Golden Kiwi and Lime. Key marketing objectives that need to be addressed Establishing a strong brand image for Feel Good Company-the Company is competing against a number of well established companies and needs to impact consumers with a captivating image. (Assmus and Farley, 1984) Making the products offered stand out- Customers need to be able to identify the company with something unique. There are a number of drinks in the market and Feel Good needs to inform customers that it is the best choice using its marketing tools.

Agree or disagree with Hawking's quotation Essay
Agree or disagree with Hawking's quotation - Essay Example While the importance of talking throughout the history of mankind in general and in the contemporary age in particular cannot be overemphasized, the author is too optimistic and unrealistic about the results talking can produce. Talking can or cannot be effective depending upon the context, participants, topic, and means of communication. For example, the governments of Pakistan and India have conducted dialogues with each other several times, but have never been able to end their differences, and the rift between the two neighbor countries continues, to some extent, even to date. Many wars in the history have reached an end as a result of dialogue between the concerned countries. There is yet a long list of world events in which the dialogues among different countries did not produce any meaningful results. Therefore, it cannot be established that no matter what problem is at hand, all that needs to be done is talking for that. If the author’s argument is supposed to be based on reality, then it is obvious that he is not talking about just any kind of talking. It would take a lot of effective talking to reach a point in time when the wildest hopes and thoughts could be materialized into reality. Effective talking can be defined as the kind of talking that occurs at the right place, in the right environment, at the right time, between the right people, and upon the right subject. But this is an ideal situation which requires a range of events to take place many of which are beyond the control of human beings. Talking is not everything. For example, the first hurdle in the way of developing such a technology is reaching a unanimous decision on its creation because such a technology is likely to harm the world in more ways than benefit it. If anybody could do whatever he/she wanted, then this world would be a mess. There are fair chances that if, ever, such a matter is discussed, there would be so many

How does modern technology affect socialization for worse Annotated Bibliography
How does modern technology affect socialization for worse - Annotated Bibliography Example This article is from the center for educational research and innovation looking for the impact that technology has in the society. The aim is to establish the attributes that affect the young learners based on the introduction of technology in schools. It understands that the best way of dealing with such attributes is by understanding that the policies in the educational sector require updating to keep students in the right frame of mind when dealing with schoolwork. This article is crucial in establishing whether the introduction of technology in school impacts kids negatively and how policies could assist in making the society better. The changes are examined while the emerging responses will be weighed to check on the impact this has on the society as a whole. The article approaches the aspect of technology evolution from both a positive and negative direction. The aim is to examine the main attributes that redefine the growing need for an understanding of the impact that technology has in the society. Many people assume that the innovations are all good, yet the demerits warrant some examination to shield the children from missing the benefits of socialization. The article will be a good addition to the topic of discussion because it will open up the need to examine what innovations do to the society and how the increasing need to compile this in the digital dictionaries is affecting the way children converse. It is becoming a common practice to find children using short codes such as lol for laughing out loud, and this can affect their conversations in the future or determine the new way they socialize. The author notes that the inclusion of technology in learning has been a viable and inexpensive solution to many of the developed countries. This means that more schools are adapting these mechanisms in their
Equipment and Books Essay Example for Free
Equipment and Books Essay Use of persons name Specific dedication for person to know why he being recognized Public display of all awards Follow-ups Timely Manner If motivation is properly handled, employees will always be happy and the organization will retain their staff for longer time periods. Educational workplaces require books and equipment such as computers, laboratory equipments, and agricultural equipments for all staff and students. If equipment is not adequate, the staff may be strained and this may cause unnecessary delays in lectures and work. Some workplaces may lack current books because of proper funding and this may pose a major challenge to the staff. Cultural Differences Educational workplaces often are filled with people from different cultures. Cultural beliefs influence human behaviors to a great extent and as cultures differ it often makes it difficult to design an environment that is conducive to performance and satisfaction. An example would be a colleague who believes that women should not expose their faces. This cultural diversity will often make it difficult for women to associate with individuals who may find difficulty in relating to them. Cultural differences influences the following in educational workplaces Mode of dressing Food served; some people eat snakes and frogs while to others don’t Associations in the institution Language used Team work In any workplace, teamwork poses challenges to many people. This is because of attitudes, values beliefs and behavior. Some individuals may have bad attitude which may affect the goal being sought after by the team, thus affecting other group members. Others may exhibit behaviors that one may not wish to associate with. In order to find compatibility, educational workplaces should have working teamwork members who encourage all individuals to associate with others without consideration of their culture. Team work may result in positive consequences for competing teams and these instances may follow: Team members becoming more close and displaying greater loyalty from its members and some members who are close in rank may bury some of their internal differences. Team climate changes from informal, casual, playful and work and task oriented members as well, while concerns for member’s psychological needs decline while concern for task accomplishment is increased. Leadership patterns tend to change from more democratic toward more autocratic while the team becomes more willing to tolerate autocratic leadership Each team becomes more structured and organized Each team demands more loyalty and conformity from its members in order to be able to present a â€Å"solid front†What happens between competing team? Each team begins to see the other teams as the enemy, rather than merely a neutral object. Each team begins to experience distortions of perception and tends to perceive only the best outcomes while denying weakness and allows competing teams to perceive only negative assumptions of the other team members while denying their strengths, as each team is likely to develop a negative stereotype of the other such as saying, â€Å"They don’t play fair like we do. †Hostility toward the other team increases while interaction and communication with the other team decreases, thus it becomes easier to maintain negative stereotypes and more difficult to correct perceptual distortions. If the teams are forced into interaction, for example, or if they are forced to listen to representatives pleading their own and the other’s causes, in reference to some task that each team, they are likely to listen more closely to their own representative and not to listen to the representative of the another’s team member, except to find fault with his presentation, in other words, team members tend to listen only for that which supports their own position and stereotype. What happens to the winner? Winners retains their confidence and may become even more cohesive Winner tends to release more tension and become more casual and playful. Winner lean towards higher intra-groups and display more cooperation and concern for other member’s needs. Winners can become complacent and feel that winning has confirmed a positive stereotype and as the negative stereotypes of the â€Å"enemy†team, there is little basis for reevaluating perceptions or reexamining team operations, in order to learn how to improve them. What happens to the loser? If the situation permits some ambiguity in the decision (if judges have rendered it as a close game), there is a strong tendency for the loser to deny or distort the reality of losing and instead, the loser will find psychological escapes such as (the judges were biased) or (the judges did not really explain the rules of the game, clearly) or possibly they may think (if luck had not been against us at the one key point, we would have won,†and so on. If loss is accepted, the losing team tends to splinter and as unresolved conflicts come to surface, fights may breaks out. A losing team member is more tense and may be ready to work harder and may be desperate to find someone or something to blame their loss on. They may blame the team leader, the judges who decided against them or even the rules or the game. (The â€Å"lean and hungry†state). A losing member may look for inter-group cooperation, have little concern for other team member’s needs or huge concern for recouping, by working harder. A losing team member often learn a lot about themselves while working as a team, because positive and negative stereotypes of the other team are upset by their own loss, forcing a reevaluation of perceptions as a consequence and a losing member is more likely to reorganize their ideas and accept their loss more realistically. J. FUNDS In a workplace, funding a project that is viewed as personal is not easy. For example, funding research by one lecturer may be very difficult, although the outcome may benefit the institution and again, some projects may be very expensive and even the institution may not have the capacity to fund the project, therefore they may need external funding. Workplace funds may also be misused by staff members.

Variable Length Hash Algorithm Using RC6
Variable Length Hash Algorithm Using RC6 Hash_RC6 Variable Length Hash Algorithm using RC6 Kirti Aggarwal Dr. Harsh K. Verma ABSTRACT In this paper, we present a hash algorithm using RC6 that can generate hash value of variable length. Hash algorithms play major part in cryptographic security as these algorithms are used to check the integrity of the received message. It is possible to generate hash algorithm using symmetric block cipher. The main idea behind this is that if the symmetric block algorithm is secure then the generated hash function will also be secure [1]. As RC6 is secure against various linear and differential attacks algorithm presented here will also be secure against these attack. The algorithm presented here can have variable number of rounds to generate hash value. It can also have variable block size. Keywords: Cryptography, Symmetric Encryption, Asymmetric Encryption, Data Integrity, Authentication, Confidentiality, Non-Repudiation, Access Control, Hash, RC6 INTRODUCTION Cryptography is the ability of keeping message secure form others while sending information between participants (Confidentiality). There are many cryptographic algorithms categorized as symmetric encryption algorithm and asymmetric encryption algorithm. Symmetric encryption algorithm is the one that use same shared key from encryption and decryption, while asymmetric algorithm is the one that use different keys from encryption and decryption. With the Confidentiality cryptography also provide other services known as data integrity, authentication, non-repudiation, access control etc. Data Integrity is assuring that data received is same as sent by the sender. Authentication is the ability to assure that communicating party is who that it claims to be. Non-Repudiation is the prevention against the denial by entities involved in the communication. Access Control is the prevention against the unauthorized use of resources [2]. Figure 1. Fundamental of Cryptography Hash Function A cryptographic hash function is any algorithm or subroutine that maps large data sets of variable length to smaller data sets of a fixed length. The values returned by a hash function are called hash values, hash codes, hash sums, checksums or simply hashes. Where h has fixed length. An (accidental or intentional) change to the data will (with very high probability) change the hash value. For a hash function to be considered secure, it must be computationally infeasible to find has a predefined hash value and similarly it must be computationally infeasible to find two messages having same hash value. RC6 RC6 is a symmetric block cipher based on RC5 and designed by Rivest, Sydney, and Yin for RSA security [3]. Like RC5, RC6 is a parameterized algorithm where the block size, the key size, and the number of rounds are variable; again, the upper limit on the key size is 2040 bits [4]. RC6 was designed to meet the requirements of the Advanced Encryption Standard (AES)competition. RC6 proper has ablock sizeof 128 bits and supportskey sizesof 128, 192 and 256 bits, but, like RC5. RC6 can be viewed as interweaving two parallel RC5 encryption processes. It uses an extra multiplication operation not present in RC5 in order to make the rotation dependent on every bit in a word. SHA-256 SHA-256 operates on eight 32-bit words. The message to be hashed is first padded with its length in such a way that the result is a multiple of 512 bits long, and then parsed into 512-bit message blocks M(1);M(2); : : :;M(N). The message blocks are processed one at a time: Beginning with a fixed initial hash value H(0), sequentially compute Where C is the SHA-256 compression function and + means word-wise mod 264 addition. H(N) is the hash of M [5]. SHA-512 SHA-512 is a variant of SHA-256 which operates on eight 64-bit words and block size of 1024 bits. It uses different shift amounts and additive constants, but its structure is otherwise virtually identical, differing only in the number of rounds, which are 80 for SHA-512[15]. HASH FUNCTION A cryptographic hash function is a mathematical transformation that takes a message of arbitrary length and computes a fixed length value also known as hash value, message digest, hash code, hash sum, checksum, etc. Where H is Hash Function, M is variable length message; H is fixed size hash value. Creating hash function is accomplished by iteration. Instead of using a hash function with variable-size input, a function with fixed size input is created and is used a necessary number of times. This fixed size input function is known as compression function. It compresses an n-bit string to create a m-bit string where n is normally greater than m. This scheme is referred to as an iterated cryptographic hash function [6]. These compression function fall into two categories: a function specially designed for the hash function or a symmetric block cipher [2]. Figure 2. Iterated Cryptographic hash Function Characteristics of one way Hash Function: Given M, it is easy to compute h. Given h, it is hard to compute M such that. Given M, it is hard to find another message, M’, such that The whole point of one way hash function is to provide a finger print of M that is unique. In some application one wayness is insufficient; we need an additional requirement called collision-resistance (It is hard to find two random messages, M and M’, such that [1]). Figure 3. Basic Hash Algorithm at sender and receiver Hash Function takes message and an initial value as an input and produces the hash value. The hash value is appended to the message at a time when the message is assumed or known to be correct. The receiver authenticates the message by generating the hash value with the same procedure and compares it with the hash value send by the sender. If both the value matches then the received message is same as it is send by the sender otherwise message has been tampered with. RC6 RC6 [7] is a fully parameterized family of encryption algorithms. A version of RC6 is more accurately specified as RC6-w r bwhere the word size is wbits, encryption consists of a nonnegative number of roundsr, andbdenotes the length of the encryption key in bytes. Since the AES submission is targeted atw= 32 andr= 20, we shall use RC6 as shorthand to refer to such versions. When any other value ofworris intended in the text, the parameter values will be specified as RC6-w r. Of particular relevance to the AES effort will be the versions of RC6 with 16-, 24-, and 32-byte keys [4]. Figure 4. RC6 Encryption For all variants, RC6-w r boperates on units of fourw-bit words using the following six basic operations. integer addition modulo integer subtraction modulo bitwise exclusive-or of w-bit words integer multiplication modulo Rotate to the left by the amount given by the least significant bits of Rotate A to the right, similarly parallel assignment Key Expansion Use two magic constants:- Where:- †¦Ã¢â‚¬ ¦.(base of natural logarithm) †¦Ã¢â‚¬ ¦..() is the odd integer nearest to . INPUT byte key that is preloaded into word array denotes the no of rounds. OUTPUT w-bit round keys . ALGORITHM For do Encryption Four w-bit registers A, B, C, D contain the initial input plain-text as well as the output ciphertext at the end of encryption. The first byte of plaintext is placed in the least significant byte of A; the last byte of plaintext is placed into the most significant byte of D [6]. INPUT Plaintext stored in four w-bit input registers Number r of rounds w-bit round keys OUTPUT Ciphertext stored in ALGORITHM C = C + S[2r + 3] Decryption For decryption of cipher-text load these cipher text into registers A, B, C, D Algorithm uses integer subtraction modulo 2w and right rotation on registers for getting plain text. INPUT Ciphertext stored in four w-bit input registers Number r of rounds w-bit round keys OUTPUT Plaintext stored in ALGORITHM HASH FUNCTION USING RC6 RC6 is a uses 44 words of key material making it more complex to break. RC6 parameterized cipher; the block size can be grown in a straightforward manner to 256 bits and beyond.RC6 has maximum key size of 2040 bits, making the corresponding hash function very fast.20 rounds using RC6 will have all these features which make the hash more efficient and secure. It is possible to use a symmetric block cipher algorithm as a hash function. If the block algorithm is secure, then the one-way hash function will also be secure. One approach is to encrypt the message with the algorithm in CBC mode, a fixed key and an initial vector (IV), the last cipher text block is the hash value. Another more better approach uses the message block as the key, the previous hash value as the output. Here we will use second approach. Algorithm presented here has variable parameters i.e. different parameter value can be taken according to the need. Block size (b), Number of rounds (r), length of hash value (l) are the different variable parameters that are the inputs of the algorithm. The length of hash value (l) should be multiple of 256. First of all padding is done. Message is padded with zeros in a way such that the padded message length is multiple of the block size (b). Then initial vector is needed to generate the hash value. Initial Vector is a piece of data is needed to begin running an algorithm, and is not secret. There are two initial vectors in this algorithm which are used to generate initial hash value. To generate the initial hash value combination of v (size of hash value divided by 256) 256 bits values calculated as follows: After generating initial hash value from initial vectors the message (M) is divided into number of small chunks (n). The size of message chunks should be equal to block size b, after that RC6 key generation is applied on each message block to generate keys that will be used to encrypt the previous hash value to generate next hash value. Initial 256 bits v hash values are encrypted via RC6 using RC6 keys generated from first message block (M1). This is then encrypted again from the keys generated from second message block (M2) and so on until all the message blocks (n) are used. At last all the v final hash values of length 256 bit each are concatenated to generate the final hash value of length l. Number of rounds (r) is divided in to two parts, 3r/4 rounds are used to generate the RC6 keys from the message block and r/4 rounds are used to encrypt the previous hash value to generate next hash value. Figure 5 shows the procedure for hash value of size 512 bits. Figure 5. Hash Value Generation using RC6 PSEUDO CODE INPUT Message M, Number of rounds r, Block size b, Length of hash value l; OUTPUT Final hash value h; ALGORITHM Pad 0s (zeros) at the end of the message so the message length is multiple of b; Divide message into chunks of size b; Repeat step 7 to 21 Load Repeat step 10 to 12 Repeat step 13 to 16 Repeat step 20 Repeat step 22 to 33 Load Repeat step 26 to 30 for do Load Concatenate to get final hash value h PERFORMANCE AND ANALYSIS This algorithm was implemented using java in NetBeans IDE 7.0.1. Following results were obtained on Intel(R) Core(TM) i3 CPU M 370 @ 2.40 GHz 2.39 GHz 32 bit system with 4 GB of RAM running Windows 7 Ultimate. Algorithm presented in this paper is compared with SHA-256 and SHA-512 respectively. Comparison between algorithm presented here and SHA are done on the basis of throughput of the algorithms and time to produce hash value for files of different sizes. To be more accurate the program is executed ten times for each input file and the average of those results are reported here. Results in Figure 6 to Figure 9 and Table 1 for Hash using RC6 are obtained for r=64, b=512, l=256 and these results are compared with SHA-256 which has same value for these parameters. Figure 6. Throughput of RC6_HASH and SHA-256. Figure 7. Bar Graph of Hash value generation time of RC6_HASH and SHA-512 Figure 8. Line Graph of Hash generation time of HASH_RC6 (256) and SHA-256 Figure 9. Execution time saving caused by Hash_RC6 Table 1. Comparison of Hash_RC6 (256) SHA-256 on the basis of Execution Time of different type of Files. Figure 6 shows the throughput of RC6_HASH and SHA-256 the algorithms in KB/sec. Figure 7 shows the Bar Graph hash value generation time (in millisec) of both the algorithms for the file of different sizes (in KB). Figure 8 shows the Line-Graph of execution time according to their file size for each file using algorithms Hash_RC6 (256) and SHA-256. Line graph is more convenient to show that Hash_RC6 (256) performs faster than SHA-256. This Graph also shows that for the file of small size both the algorithms performs approximately same i.e. there is not much of the difference but when the file size increases Hash_RC6 (256) performs much better than the SHA-256. Bar chart in Figure 9 shows the execution time saving caused by Hash_RC6 in percentage in comparison with SHA-256 for different file sizes. It’s greater than 30% for almost all the file sizes and for some of the file sizes its approx 50% that is greater advancement. The average percent execution time saving by Hash_RC6 for hash value of 256 bits over SHA-256 is 40.26. We compare the execution time of each algorithm on different file types like text file, audio file video files, for this purpose we mainly used 10 files and recorded their hash value generation time in milliseconds for these algorithms. List of Input files and their size are given in Table 1. Results in Figure 10 to Figure 13 and Table 2 for Hash using RC6 are obtained for r=80,b=1024,l=512 and these results are compared with SHA-512 which has same value for these parameters. Figure 10.

Figure 10 shows the throughput of RC6_HASH and SHA-512 the algorithms in KB/sec. Figure 11 shows the Bar Graph of hash value generation time (in millisec) of both the algorithms for the file of different sizes (in KB). Figure 12 shows the Line-Graph of execution time according to their file size for each file using algorithms Hash_RC6 (512) and SHA-512. Line graph is more convenient to show that Hash_RC6 (512) performs faster than SHA-512. This Graph also shows that the difference is not so much for file of small size but when it comes to file of larger size Hash_RC6 (512) is much better than the SHA-512. Bar chart in Figure 13 shows the execution time saving caused by Hash_RC6 (512) in percentage in comparison with SHA-512 for different file sizes. It’s greater than 15% for almost all the file sizes and for some of the file sizes its approx 35% that is greater advancement. The average percent execution time saving by Hash_RC6 for hash value of 512 bits over SHA-512 is 24.625. We compare the execution time of each algorithm on different file types like text file, audio file video files, for this purpose we mainly used 10 files and recorded their hash value generation time in milliseconds for these algorithms. List of Input files and their size are given in Table 2. CONCLUSION In this research paper a new algorithm for generating hash value is presented. This algorithm is generated on a symmetric block cipher known as RC6 and can generate hash value of different sizes. The algorithm can also operate on different block size and different number of rounds. The implementation of algorithm is done using JAVA in NetBeans IDE 7.0.1. on Intel(R) Core(TM) i3 CPU M 370 @ 2.40 GHz 2.39 GHz 32 bit system with 4 GB of RAM running Windows 7 Ultimate. Hash value generated using algorithm presented here are secure against many attack because when a hash algorithm is generated using symmetric block cipher it inherit the properties of underlying cipher. The idea behind this is that if the symmetric block algorithm is secure then the generated hash function will also be secure [1]. Then the algorithm is compared with SHA-256 and SHA-512 for same parameter and on the same environment. The results of comparison conclude that the algorithm present here has better throughput
