Essay on Juvenile Violence in Public Schools - 1368 Words

The starting point of violence takes place in communities and at home--not at school. Youth take what they hear and see at home and in their communities to school. The environment in some communities and households are positive and the presences of protective factors outweigh the high risk factors. However, there are communities and households where there is a lack of informal social control and high risk factors exist more than protective factors--, which affect youth in a negative manner. A sudden increase of youth violence in public schools in early 1990 has caused many to raise concerns about violent behaviors in schools. In the past, the most common form of violence that took place in schools was bullying, physical fights, or†¦show more content†¦Violence in schools develops for the most part from factors external to schools. However the school environment might aggravate those factors. The portrayal of violence on television is shown in cartoons, comedies, horrors, dramas, and many other genre television shows. Some cartoons as well as other television shows, endlessly display violence--that youth often view as a form of entertainment. However, the actions and behavior conveyed on the television do not make youth commit violent acts. It induces them to believe that violence is just the standard way of living life. On the television, the lawbreaker gets away with the crime and does not face disciplinary actions, and therefore they are not held responsible for the repercussions of their wrongdoings (Menhard 11). The Juvenile Justice: Policies Programs, and Practices, believes that schools that have an unconstructive or a negative environment, as well as an excessive amount of misbehavior and conflict between the faculty and students, and students against other students, are issues that can trigger juvenile violence in schools. In addition, juvenile violence tends to happen more often in high schools and middle schools that are located in poor urban areas (Taylor, Fritsch, and Caeti 58-60).

Propaganda During The 20th Century And The Onset Of World War

Propaganda has always held sway over hearts and minds. Although the United States’ first large-scale wartime experience with propaganda in its semi-modern form of ‘yellow journalism’ took place during the Spanish-American War , primitive forms of it have existed since the days of â€Å"the tattoo-covered Caddo warrior, whose body attests to every victory, accomplishment, or god worshiped† and â€Å"Hannibal’s titanic war elephants advancing across the Italian plain.† Even â€Å"the ‘rebel yells’ of Confederate soldiers proclaiming that a charge was about to ensue† can be considered a sort of propaganda because in its most simple definition, propaganda is â€Å"the manipulation of opinion.† However, the modern propaganda which Americans are most familiar with is well summed up by the Merriam-Webster definition: â€Å"ideas or statements that are often false or exaggerated and that are spread in order to help a caus e, a political leader, a government, etc.† The beginning of the 20th century and the onset of World War I marked the beginning of the true modern propaganda era, and throughout the 20th century, propaganda has grown in scope and influence, as well as been altered in how it is disseminated among and marketed to the people. â€Å"‘There is little exaggeration,’ wrote political scientist Harold Lasswell in 1938, ‘in saying that the World War led to the discovery of propaganda both by the man in the street and the man in the study.’† Indeed, in the period directly after WWI, propaganda, aShow MoreRelatedThe And Collective Anti Semitic Violence1679 Words   |  7 PagesCollective acts of violence during the late nineteenth century and early twentieth century became more prominent and apparent since the Civilizing Process meant that violence was no longer an inherent part of everyday life.

Nursing Reflection Free Essays

Going back through previous experiences and tracing back the footsteps we have made allows us to reminisce about the good things that have happened in our lives. Somehow the undesirable memories would also seep in as they are part and parcel of our existence that we cannot do away with. This process gives us an opportunity to encounter past events that can necessarily aid us in the future. We will write a custom essay sample on Nursing Reflection or any similar topic only for you Order Now In the Nursing practice, reflection is a retrospective approach that evaluates historical processing of experiences that takes place in a structured form and is deemed highly essential (Eliis, Kenworthy and Gates, 2003, 156). In the clinical practice, this retrospective activity facilitates in the promotion of quality care. The art of reflection however in the nursing practice focus on self rather than on the situation as the care provider (Quinn, 2000, 252). The process is a reflective practice that is a cognitive act by which we are allowed to make sense of our thoughts and memories (Taylor, 2000, 43). This method therefore allows a practitioner to generate a complementary or alternative form of knowledge and a set of choices in the evaluation of the best course of action. It is a â€Å"deep learning† experience that reflects on our knowledge and theories and go beyond merely thinking about what we do but involves recalling what had occurred and analyzing the situation by interpreting important information recalled (Taylor, 2000, 4). In Nursing, the reflective process is aimed about our own practice (Taylor, 20000, 3); that nursing education and research cannot do without as a common practice in the learning mechanism in which we all engage in a regular basis (Slevin and Basford, 2000, 483). With a main purpose of enabling the practitioner to learn from experiences and increase clinical effectiveness, reflection is highly essential to the nursing practice. For this process to be effective, Johns has provided a guided reflection which employs different models of self-inquiry to enable a practitioner to realize desirable and effective practice (2002:3). Considering that this involves a cognitive and emotional component that is expressed through analysis, different models would aid us feel comfortable about the activity. John’s model can be used in preparation for or during clinical supervision and applicable to specific incidents rather than more general day to day issues and particularly applicable to those who prefer a structure approach (Ellis, Kenworthy and Gates, 155). Gibbs Model use term description rather than â€Å"a return to the entire experience† as a form of reflection is considered as a simpler method but one where a mentor or facilitator is likely needed(Davies, Bullman and Finlay, 2000, 84). Both models however in supervision practice can be used to facilitate clinical governance through the promotion of quality care where an exchange between two professionals employing this technique seeks to improve their practice (Watkins, Edwards and Gastrell, 2003, 266). To maximize the potential benefits of clinical supervision, nurses have to learn to be comfortable with this retrospective activity with the aid of Gibbs or John’s models depending on where one feels most comfortable working with (Ellis, Kenworthy and Gates, 156). Gibbs Model for reflection As a simple and easily attainable method, Gibbs model uses term description rather than a return to a previous experience (Davies, Bullman and Finlay, 84). In psychology and teaching, reflection facilitates as purposeful change and competencies such as psychological-mindedness and self-regulation (Clutterback and Lane, 2004, 196). Usually this process involves a mentor, teacher or supervisor working with a student at different stage while allowing for individuality. Although less specific than re-evaluating an experience; Gibbs in his cycle or reflection makes the action planning a more overt component of reflection (Davies, Bullman and Finlay, 84). Gibbs provides that in one’s own practice, an essential aspect of working as an autonomous practitioner involves a critical analysis of one’s role and responsibilities from a personal perspective (Gibbs, 1998,13). It is a process that requires others to become involved that encourages feedback and constructive comment to recognize your role and value in a health team (Humphris and Masterson, 2000, 77). John’s Model for reflection John’s model uses the concept of guided reflection to describe a structure supportive approach that helps the practitioner learn from their reflections and experiences (Quinn, 2000, 572). The approach involves the use of a model of structure reflection, one-on-one group supervision and the keeping of a reflective diary (Quinn, 572). The practice would aid the practitioner in learning from a reflection of their experiences. John’s model is more detailed as it provides a checklist of specific points necessary for reflection (Davies, Bullman and Finlay, 85). The only problem cited with John’s model if it imposes on a framework that is external to the practitioner leaving little scope for inclusion as cite by other theories. John’s model can be used in preparation and during clinical supervision consisting of 6 steps that is applicable t specific incidents rather than more generalized day to day issues facing the supervisee (Ellis, Kenworthy and Gates, 155). This model is highly attractive to those who prefer a structured approach but others may find this type more restricting (Ellis, Kenworthy and Gates, 156). Criticisms against the reflective process Reflection involves cognitive and emotional components that are expressed through analysis and to maximize the potential benefits of the clinical supervisor nurses have to learn to feel comfortable with this retrospective activity both during and in preparation for supervision sessions (Ellis, Kenworth and Gates, 157). This could be deemed time–consuming in an institution where time is often an important element in the delivery of care. A time for reflection can be done positively only when a situation or a need arises. This is probably why reflection method is considered a radical approach to nursing education and practice given the ample time training can afford (Slevin and Basford, 483). Yet reflection is valuable if done in partnership with someone else which led Davies et al to believe that the approach is quasi-therapeutic (Davies, Bullman and Finlay, 86). The principles have been transferred directly from client-centered psychotherapy and may trigger more powerful responses such as guilt and anxiety. Practitioners are therefore evaluated before they are given a chance to try this one out according to conservative studies. However with practice, it is assumed that a reflective process may not hold as much negative impact for the learned practitioner in an answer to the demands for a continuous review of a practice in a critical and analytical manner that support the reflective concept. The Value of Reflection for the Student Nurse As an essential component of scholarly practice, reflection, reflection is a method for generating a complementary alternative form of knowledge and theory (Humphris and Masterson, 2000:78).   Regardless of any negative criticism a reflective method may elicit from critics, I consider this to be a valuable tool. For the student, this is a process were one internally examines and explores an issue of concern triggered by an experience that clarifies the meaning of perspectives (Canham and Bennett, 2001, 185). The nursing practice has been surrounded by a world of silence and reflection is a way for nurses to reflect that is enhanced and introduced in the nursing curriculum (Guzzetta, 1998, 102). Often in the professional practice, nurses have encouraged silence among themselves in their health environment and setting while usually developing a shared professional voice with her team. Oftentimes, her relationship with the rest of the health team and other professionals faced difficult efforts because of the autonomy. The process of reflection allows one to air out her sentiments and ideas within her group or to a mentor or a supervisor during moments of reflection that could be produced as a shared voice for the team. Developing a habit of reflection is therefore a must for nursing education in order to uncover dimensions of experiences such as hidden and explicit meanings of behavior that can aid a student nurse in identifying her own perspective of the nursing practice that is highly useful in her entry to the profession (Guzzetta, 1998, 103). For a student in nursing, one must therefore develop a habit of reflection in order to uncover experiences and the meaning of behavior, values and thoughts that could readily prepare one for professional practice. It should be noted that the reflective process can helpfully aid in teamwork where one has the chance to relay sentiments after reflection of her past experience.Nursing education must therefore develop and evaluate innovative strategies to prepare nurses to meet the challenges of the rapidly changing health care system and for lifelong learning (Johns and Freshwater, 1998, 149). Reflection and reflective practice are currently receiving attention as a strategy yet little is known about the process of becoming a reflective thinker, how to teach skills needed for reflection, or the barriers and facilitators to becoming a reflective practitioner (Clutterback and Lane, 2004, 198). However a reflection process is worthy of study and practice that should initially be started and adapted as a core training for everyone wishing to professionally practice nursing as a positive way to analyze the development of reflective practice abilities.

International Business Healthcare

Question: Write an essay on International Business? Answer: 1. Introduction Healthcare sectors operate on the basis of high patient satisfaction rates and positive perceptions of the patients about care quality in heath sectors. According to Bryman (2012), patients satisfaction of the care quality is the major factor that will provoke the patient to avail the services of the healthcare in future. Furthermore, the rate of better health outcomes are also triggered by high satisfaction rates within the healthcare organization. However, the satisfaction level of the patients is hampered when a gap arises between the perception level and the actual service received within the healthcare organization. The researcher in the current report will focus on analyzing the experiences of the patients about the care quality facilities in Mayo Clinic, USA. 2. Research problem Recent surveys show that around 54% of the American citizens are dissatisfied with the quality of care provided by the healthcare organizations of USA (Abcnews.go.com, 2016). Lack of effective care systems within the USA hospitals is making it difficult for the Americans to use prolonged treatment facilities. Thus as per the reports of WHO, the rate of chronic diseases in USA has increased by around 5% (Who.int, 2016). The researcher in this study has focused on observing the experiences of the patients treated by May Clinic in USA. Mayo Clinic is one of the largest and first hospital services that were opened in USA. The clinic employs around 3800 doctors and nurses and caters to the needs of around 60% of the US population (Mayoclinic.org, 2016). However, the hospital was recently facing complaints of errors within the laboratory tests, lack of nurses and doctors in emergency wards, lack of effective care for senior patients, ineffective service during night shifts and unhygienic c onditions within general wards (Donley, 2012). The organization spends around $ 500 million for development of healthcare quality within the hospital (Mayoclinic.org, 2016). However, the reductions in the number of patients are threatening the revenue levels of the hospital. Thus, the researcher focused on the research problem of patients experience of the care quality in the hospital and provides necessary recommendations for the problem. 3. Use of qualitative methodology for research According to Dicks (2012), qualitative research method is generally used in case of research problems where less information is available and no prior research has been conducted. In this researcher the researcher will use the qualitative research method to successfully obtain the experiences of the patients who have undergone treatments in Mayo Clinic. The researcher for the purpose of research will select direct in-depth interview process which will help the researcher to use open-ended questionnaire for face-to-face interviews. The researcher will conduct 30 minutes interview with each patient and also their family members and understand the problems faced by the patients for treatment services in Mayo Clinic. The qualitative method will help the researcher to gain insights into the perception of patients related to care quality in healthcare organizations and identify the gaps of service quality in services offered by Mayo Clinic. 4. Research purpose Gornall (2013) stated that it is important for the patients to be highly comfortable and satisfied with the services of the hospital in order to get quick recovery. The researcher has selected the current research topic in order to help the healthcare sector of USA to improve the facilities. As per the WHO reports, the persisting numbers of chronic diseases within more than 60% of the US population are reducing the quality of human capital in US (Who.int, 2016). The deteriorating condition of the healthcare organizations operating in US are the major reason behind the rise of the rate of chronic diseases. Further, death rate in hospitals of US has increased due to the high rate of hospital negligence. The major purpose behind selection of the topic is to help Mayo Clinic attain its previous position as the most benefiting healthcare organization of USA. 5. Research questions The researcher will conduct the research based on the following research questions: What were your expectations about the quality of care system before availing the services of Mayo Clinic? What are the major problems faced during the treatment process in Mayo Clinic? What are the major recommendations you would like make that would improve the present care quality system of Mayo Clinic? 6. Research design Researcher in this study will focus on using descriptive research design for conducting of the qualitative research process. According to Holmes (2013), usage of descriptive research designs helps researchers to observe the research respondents and describe the responses in an accurate manner with help of pre-existing theories. Descriptive designs help researchers to obtain responses to questions like What, Why and How. In this study the researcher will select 20 respondents using the random sampling method. The respondents will include patients discharged from Mayo Clinic, families of patients being currently treated in Mayo clinic and patients undergoing prolong treatment in May Clinic. 7. Justification for selection of qualitative method The researcher in this study aimed at understanding the perception, problems, opinions and suggestions of the patients and their family members about healthcare services of Mayo clinic. Thus, qualitative research method will help the researcher to make successful analysis of the human behavior. Tolich (2013) argued that quantitative research method is generally used in case if the researcher needs to calculate trends, test relationships and determine cause-effect nature of any research problem. The use of qualitative method in this study will also save the time of the researcher as the researcher can use a small sample of patients to analyze the problems existing within the healthcare sector of USA. Further, the experience of the patients cannot be recorded with close-ended questions hence the researcher has adopted qualitative method which will provide the opportunity of using open-ended questions for the researcher. 8. Conclusion The researcher report shows that the researcher is justified in selecting qualitative researcher method for analyzing the opinions and suggestions of patients related to healthcare services of Mayo clinic. The problems arising within Mayo clinic confirms the fact that there is need for the research. The gaps identified between the patients perception level and the actual care services offered will help to understand the required levels of improvements that should be done by Mayo Clinic to ensure high quality care service in USA. 9.

My scores are ranked in the following manner; the hostile sexism score is 3.45 and the benevolent sexism score is 3.36. They are somehow related to the average scores of men and women who have taken the record of scores from a cross-cultural perception. For instance, in an African country such as Nigeria, when comparing it with my country, benevolent sexism score is 3.6 and hostile sexism is 2.5. In central Asia, hostile sexism score is 3.3 and benevolent score is 3.1. In addition, a European country such as Netherlands has a hostile sexism score of 1.9 and benevolent sexism score of 2.4. Lastly, Latin America such as Spanish has a hostile sexism score of 2.5 and benevolent score of 2.2 (Glick and Fiske, 2001). What does this tell you about your own attitudes toward the roles of men and women? From my outlook basing on the score analysis above, women seem to be dominated by men especially in the workplace. The scores above indicate that some countries whereby cultural gender roles are attached especially the roles of women in the society have high scores on hostile sexism (Muratbekova-Touron, 2008). This means that women in such countries are discriminated in that they cannot perform duties that men can perform. Regardless of male dominance, men are usually dependent on women as wives and romantic collaborates something that fosters benevolent sexism. In addition, male dominance is widespread in all countries with men holding high positions in areas such as businesses, non-governmental and governmental institutions. What does this tell you about the differences in the average male and female attitudes and perceptions among the countries you selected? This tells me that the differences in the average male and female attitudes and perceptions among the countries selected above are brought about sexism. Prejudice creates an imbalance between male and female especially in working environment (Fontaine, 2007). Some countries such as Nigeria that is among the African countries have different gender roles that specifically belong to a certain group of people. This is different in the Latin American and the European country where sexism is not common thus brings about the slight difference when comparing the average score. What insights did you gain through this exercise? This exercise has helped me to gain knowledge especially on what is being required in order to avoid sexisms. It has enabled me to understand the importance of cherishing and protecting other people in the society. For instance, benevolent sexism sometimes seems to be harmless but we should be careful because it has a devastating effect on the society. In what ways do you think the inventory might be improved? The inventory or the above list should be improved through educating people on the importance of creating gender diversification across all sectors in the economy (Hickman, 2011). People should be educated to avoid sexism. In addition, there should be change in leadership restructuring to include all women in various work places as leaders. It should be invented in a way that can eliminate prejudice between male and female. Organizations should embrace uniformity across all sectors to avoid prejudice. In what ways does this relate to human resource management policies and practices? This is related to human resource management policies and practices because sexual differences have been used in various organizations to justify the position of men and women in the work place. Many male human resource managers are mostly given the high position or leadership in an organization unlike female counterparts (Shen, Chanda, Netto and Monga, 2009). The research carried out in the United States indicates that women in most societies do not enjoy the same opportunities as men. In organizations such as business entities, women are discriminated based on sex. The research indicates that the numbers for men outdo that of women in occupations such as the senior financial management or other resources management. References Fontaine, R. (2007).

Non Alcoholic Carbonated Drinks Essays

Non Alcoholic Carbonated Drinks Essays Non Alcoholic Carbonated Drinks Essay Non Alcoholic Carbonated Drinks Essay Essay Topic: Marketing According to AC Nielsen, beverages dominate the list of fastest growing food and beverages categories in the global market place. While water (still and carbonated) was the leading food and beverages product, carbonated beverages experienced 6% of growth rate (2000-2001). Soft drinks consumption worldwide is growing by around 5% a year, according Global Soft drinks 2002. Averagely, the market grew by 5% 6% per year. The zeniths 2002 global soft drinks report indicates that carbonates are the biggest soft drinks sector with 45% of global volume. Besides that, the report also shows that North America is the largest soft drinks market with a 27% volume share in 2001 and the fastest growing countries were Asia, East Europe and the Middle East. Zenith Research Director, Gary Roethenbaugh commented that the highly populous and rapidly emerging markets, such as China and India, consumption in Asia is projected to overtake that of North America in 2006. The overall sustainable growth of soft drinks in the beverages market provides marketer and manufacturer of non alcoholic carbonated soft drinks tremendous opportunity as well as challenges to realize the full potential of the market. To capitalize on the opportunities of the growing market, successful marketers concentrate effort to learn more about their consumers. Most of the time, marketers focus mainly on understanding the consumer decision making process, however, the internal and external influences that affect the overall decision making is also equally important. Consumer Decision Making Process Although consumers of a particular group may be similar in appearance and speaks the same language, that does not always mean they have the same product needs, preference and shopping behaviour. Therefore marketers need to develop a deeper understanding of the psychological, personal, social and culture of the consumers. These are the characteristic that influences the consumers response towards the marketing stimuli which will then affect the consumer decision making process. Most marketing and consumer behaviour books suggest that consumers go through a five-stage decision making process in any purchase. Based on the diagram illustrated in Diagram 1, it is important that marketers consider the whole buying process rather than just the purchase decision as it may be too late for a business to influence the choice made. In most cases, customers pass through all stages in every purchase, however, in more routine purchases, for example toothpaste, household cleaning detergents, customers often skip or reverse some of the stages. For example, a student buying his/her favourite soft drink would recognize the need, in this case thirst and go right to the purchase decision, skipping info search and evaluation. Cultural Factor Country of origins, cultural heritage, language and recent histories, all influences beverage consumption. Successful marketers use these factors to drive decisions about product assortment and marketing in order to appeal to the target market. Culture is the most basic cause of a wants and behaviour. Growing up children learn basic values, perception and wants from the family and other important groups. Marketers of non alcoholic carbonated beverages should always spot cultural shift which might point to a new product that might be wanted by customers or to increase demand. For example, the cultural shift in Malaysia towards greater concern about health and fitness has provided an opportunity to Coca-Cola Light. During the Coca-Cola Light in Kuala Lumpur, Mr Reiner Becker, Country Manger of Coca-Cola Malaysia, said that Coca-Cola Light is intended to be a great-tasting light beverage for consumers currently drink other beverages such as water, tea and juices. (www.prdomain.com/companies/c/coke/news_release.html) Malaysian consumers told us they want to treat themselves, yet they also want to take care of themselves, said Becker. Coca-Cola Light was developed to address this trend. Its got great taste, no calories and imagery that appeals to people who treat themselves as priority. Each culture contains sub cultures, which are groups of people with share values. Sub-cultures can include nationalities, religions, racial groups, or groups of people sharing the same geographical location. Sometimes a sub-culture will create a substantial and distinctive market segment of its own. For example, the youth culture has quite distinct values and buying characteristics from the much older generation. Pepsi uses celebrities like Siti Nurhaliza in Malaysia and F4 in Taiwan for its advertisements to influence the younger generations attitude. Social Factor A consumers buying behaviour is also influenced by social factors, such as the groups to which the customer belongs and social status. Coca-Cola has segmented its consumer into 4 groups which consists of the fashionable brand conscious consumer, average consumers, peer pressure consumers and coke addicts. Based on the 4 segments, the fashionable brand conscious consumer and peer pressure consumers clearly sets the example of group influenced purchased decision. The fashionable brand conscious consumers are generally in their twenties, who are universities students or make up the working class, drive fast cars (or would like to), they socialize with friends, go to parties and dance clubs. They are carefree and are freestyle. When they buy Coca-cola, they buy image, they buy fashionable drink that exudes coolness. On the other hand, the peer pressure consumers tend to be the late majority teenagers who purchase Coca-cola because their friends do it or they do not want to appear daggy purchasing a Sarsi or Sprite. They are less likely to request for Sprite or Sarsi instead of a Coca-Cola when purchasing a value meal at McDonalds for fear of dagginess. (www.coke.com) In a group, several individuals may interact to influence the purchase decision. The typical roles of an individual are initiator, influencer, decider, buyer and user. In the case of carbonated beverages, because it is a low involvement product, most of the time its target consumers could play all the roles at the same time. Motivation Most often, we human mislead ourselves when we attempt to explain our behaviour in our desire to act as retinal human beings. Sometimes we do not want to admit or even realise the real reason for our behaviour because it is, more often that not, irrational. Relating this back to marketing, it is clear that a brand or organisation has both an identity and a personality. When consumers are asked the reason why they buy a brand they will respond rationally and often describe the brands identity, such as the objective or explicit characteristics observed by the conscious thinking brain which are easily verbalised. However, a brand also has a personality, intangible traits that differentiate it from its competitors which we experience but cannot easily verbalise. For example, most consumers initially cite taste as the reason why they consume a certain brand of cola soft drinks. However, during a blind taste test conducted by Pepsi to challenge Coca-Cola drinkers, most loyal consumers could not differentiate their favourite brand. The truth is that these consumers are motivated by a group cohesion, equality and bonding towards the brand. Changes in Asia Pacific The family unit is usually considered to be the most important buying organisation in society. It has been researched extensively. Marketers are particularly interested in the roles and relative influence of the husband, wife and children on the purchase of a large variety of products and services. There is evidence that the traditional husband-wife buying roles are changing. Almost everywhere in the world, the wife is traditionally the main buyer for the family, especially in the areas of food, household products and clothing. However, with increasing numbers of women in full-time work the traditional roles are reversing. Besides, children also play an important role in influencing the buying decision making. In relation to this, and as consumers lifestyles is becoming increasingly demanding, the non alcoholic carbonated industry has become more competitive. Manufacturers are introducing new carbonated drinks such as additional of flavours and attractive packaging to capture market share. For example, Pepsi has introduce the Pepsi Blue, a blueberry flavour drink in addition to its typical cola and diet cola drink, provides consumers additional choices and varieties. The shopping and purchasing habits of consumers are also changing. People are working longer hours than before and as mentioned, many married woman with kids are also working. Todays shoppers want convenience of longer opening and trading hours and Sunday opening which most of the supermarkets and convenience store are doing nowadays. However, the implication for these retailers to work hard in order to maintain customer loyalty made marketers of carbonated drinks to work even harder because more shopping trips means shopper have more opportunity to be disloyal to a brand. Besides, consumers purchasing habits now emphasize on value, convenience and variety. Furthermore, with the advancement in technology, consumers especially the younger generation are buying soft drinks through SMS. Manufacturers who are not adopting this trend are losing opportunity. For example, Coca-Cola drinkers in Singapore are able to order Coca-Cola through sending SMS from their mobile phone and the mechanism work as a vending machine too. With the recent September 11th case, many Muslims countries have conducted boycotts towards American brands. As such, brand like Coca-Cola has been affected in these Muslims countries. As mentioned, cultural shifts towards greater concern in health and fitness may affect the demand for carbonated beverages because the increasing promotion of other health beverages such as cultured milk and traditional drinks creates greater competition. The speed of these changes has created increased pressure on manufacturers and marketers. The challenge for the carbonated drinks marketer is to understand its affect on demand for their products. Everyday, consumers around the world make decision on whether to buy or not to buy a product or brand or opt for that of a competitor. Some are decides when and where to shop. A marketers advertising, direct marketing, merchandising, packaging and point of sale materials affects all these decisions, as are shoppers own motivations and feelings about the shopping occasion and experience. Thus, the promotional mix needs to be changed to attract consumers and maintain their loyalty towards their product. Understanding human needs is critical for effective targeting marketing. However, these needs are not always detectable. The underlying motivations that most of the time marketers are not fully aware of helps maximise the potential of the brand if identified. Conclusion Understanding the changing needs of consumers and effective strategic marketing is critical to stay ahead. It is also important to understand brand relationship by exploring core needs of consumers and how consumers relate to the personality of a brand. For both manufacturers and retailers of carbonated beverages, success and failure is often a result of effective utilisation of market information to meet consumer needs and hence drive sales and profit.

Reflection - Assignment Example This would affect the economical development with the abandonment of some services. Austerity measures applied by the administration because of the increasing aging population would cause diminution in the living standards. Labor supply would get affected negatively by causing skilled employees numbers to drop causing exceptional hike in the cost of labor. Lower savings would negatively affect the actual Gross Domestic Product. The lower saving would be because of reduced savings attributable to the high numbers of retirees, who would not be saving anymore. The Canadian physical capital stock would also extensively reduce because of the reduced savings that would create a diminishing impact on real capital per head. Increased immigration in Canada helps in balancing the effects of the increasing dependency ratio by supplying skilled economic skills to the Canadian economy. However, it is worth to note that increased immigration of skilled workers does not necessarily imply economic growth and development. The effects of immigrant workers are largely neutral on the economic performance. On the flipside, increasing numbers of immigrants cause pressure on the government for provision of basic services such as housing and other administrative services. These pressures may negatively affect the government and spills to the economic performance. Canadas Aging Population May Create $67-Billion Annual Budget Hole: Study. (n.d.).

Reducing Secondhand Smoke on Children Research Paper - 4

Reducing Secondhand Smoke on Children - Research Paper Example So the one sure shot and authentic way of curtailing second hand smoke in the case of children is to convince the adults and guardians to quit smoking. Once the parents and guardians quit smoking it automatically removes the source of secondhand smoke at home and in the family car where the children are most vulnerable of catching on secondhand smoke and fumes (Harutyunyan et al., 2013). If this is not possible than the second best option is to request the family members and people in general not to smoke at home and in the family car (Harutyunyan et al., 2013). Besides the parents need to make it a point to assure that the people who take care of children like babysitters and nannies do not smoke around children. The others possible place where children could get exposed to secondhand smoke are the places, including the public places where smoking is allowed (Gordon, Friel, & McGranachan, 2012). Any child visiting such a place, including say a public space is poised to get exposed to secondhand smoke. So parents and guardians should look to it that they do not visit such places with their children where smoking is allowed. Keeping children away from public places where smoking is allowed is one salient way of cutting the secondhand smoke on children (Stosic, Milutinovic, Lazarevic, Blagojevic, & Tadic, 2012). This includes choosing such restaurants and recreational places which are smoke free or where smoking is not allowed (Stoic et al., 2012). This also tends to include such indoor places where smoking is allowed and where children are more likely to get exposed to secondhand smoking. It is a known fact that secondhand smoke causes greater harm when it is inhaled at such places which are c losed or are not well ventilated. The parents and guardians do need to understand the fact that secondhand smoke is utterly hazardous and could wreck havoc on the health and well being of

The origin, growth and development of Japanese art and culture Term Paper

The origin, growth and development of Japanese art and culture - Term Paper Example Most of the Asian fashion designs might seem to be imitations of the European styles, but this is not the case in actual sense. On the other hand, it would be absurd to ignore the impact that the Western countries have had on the East. In the entire development period which was most vibrant during the twentieth century, aesthetics and other methods where gotten from the European countries and many Asians where proud to recognize the efforts of Western countries. As the poet Tekkan once mentioned, â€Å"We love the poetry of our predecessors, who are both from the West and the East† (Arrowsmith, 2011, p.28). The beginning of the Metropolitan Court Culture By the occurrence of the Heian period, which was between 794-1185, the Japanese governing system was not fully transformed. During this period, power in Japan had been transferred to the emperor and his ministers. The quasi-independent aristocracy was now changed to the metropolitan elite that comprised of the rituals, intrigu es, history and the imperial courts. The most fundamental happening during this revolution was the adoption of the Chinese cultures and civilization. In 618, a dynasty known as Tang was established and it reigned for almost 300 years. During this period, most of the Chinese cultures acquired their flowering and maturity. ... These styles were unique, and an example is the three dimensionality and realism by the use of models in visual arts. In no time, the art designs and models came to be known as Tang International Styles (Mason, 2005, p.41). The Art of Buddhism Buddhism is one of the earliest arts that were established in China. By the mid years of the fifth century, Koguryo and Paekche, which were all Korean kingdoms, had adopted the art of Buddhism. Silla also adopted the art during the same period as the Korean kingdoms. During the Tang, just as the other Chinese dynasties, the Buddhism community played a vital role in the general affairs of the nations that adopted it. With well located monasteries and temples, the Chinese empire was inhabited by the Buddhist community that managed to make the Tang emperor the most supreme authority on the planet. In an artistic view, the Buddhist community can be said to be the richest, as arts lead to wealth and influence. As the Tang International Style is stil l embraced and praised in the four corners of the earth, its originality is reflected on the surviving paintings and sculptures of the Buddhists (Mason, 2005, p.41). The Paekche embassies, including that of 584 and 552, were unable to introduce Buddhism to Japan. However, they managed to attract the attention of Prince Shotoku who was a champion of the Buddhist cause. By 587, Buddhism had gained control in the Japanese Imperial government and was in fact a crucial foothold. In less than a century, the art has spread and was now in Yamato itself, under the regimes of Tenmu the emperor and Jito the empress who was Tenmu’s successor. Jito officially advocated Buddhism as one of the vital instruments in the

The Evolution Of Database Management System

The Evolution Of Database Management System In the ancient times when there was no computer, the data began to be stored in voluminous data repositories, called books. And eventually with the improvement in technology and expansion in knowledge the whole communities of books transferred to the first real database libraries. The main objective of the database is to ensure that data can be stored and retrieved easily and effectively. It is a compilation of data (records) in a structured way. In a database, the information is stored in a tabular form where data may or may not be interlinked. Hence we can say that basically database is a compilation of database files and each database file is further a collection of records. Database models: Flat files (1960s 1980s): Flat file database is a database that stores information in a single file or table. In a text file, every line contains one record where fields either have fixed length or they are separated by commas, whitespaces, tabs or any other character. In a flat file database, there is no structural relationship among the records and they cannot contain multiple tables as well. Advantages: Flat file database is best for small databases. It is easy to understand and implement. Fewer skills are required to handle a flat file database. Less hardware and software skills are required to maintain a flat file database. Disadvantages: A flat file may contain fields which duplicate the data as there is no automation in flat files. If one record is to be deleted from the flat file database, then all the relevant information in different fields has to be deleted manually making the data manipulation inefficient. Flat file database waste the computer space by requiring it to keep the information on items that are logically cannot be available. Information retrieving is very time consuming in a large database. Implementation of a flat file database: Flat file database is implemented in: Berkeley DB SQLite Mimesis TheIntegrationEngineer etc. Hierarchical database (1970s 1990s): As the name indicates, hierarchical database contains data in a hierarchically-arranged data. More perceptively it can be visualized as a family tree where there is a parent and a child relationship. Each parent can have many children but one child can only have one parent i.e.; one-to-many relationship. Its hierarchical structure contains levels or segments which are equivalent to the file systems record type. All attributes of a specific record are listed under the entity type. In hierarchical database, the entity type is the main table, rows of a table represent the records and columns represent the attributes. In the above figure, CUSTOMER is the parent and it has two children (CHCKACCT SAVEACCT). Advantages: In a hierarchical database pace of accessing the information is speedy due to the predefined paths. This increases the performance of a database. The relationships among different entities are easy to understand. Disadvantages: Hierarchical database model lacks flexibility. If a new relationship is to be established between two entities then a new and possibly a redundant database structure has to be build. Maintenance and of data is inefficient in a hierarchical model. Any change in the relationships may require manual reorganization of the data. This model is also inefficient for non-hierarchical accesses. Network database (1970s 1990s): The inventor of network model is Charles Bachmann. Unlike hierarchical database model, network database allows multiple parent and child relationships i.e., it maintains many-to-many relationship. Network database is basically a graph structure. The network database model was created to achieve three main objectives: To represent complex data relationships more effectively. To improve the performance of the database. To implement a database standard. In a network database a relationship is referred to as a set. Each set comprises of two types of records, an owner record which is same as parent type in hierarchical and a member record which is similar to the child type record in hierarchical database model. Advantages: The network database model makes the data access quite easy and proficient as an application can access the owner record and all the member records within a set. This model is conceptually easy to design. This model ensures data integrity because no member can exist without an owner. So the user must make an owner entry and then the member records. The network model also ensures the data independence because the application works independently of the data. Disadvantages: The model lacks structural independence which means that to bring any change in the database structure; the application program must also be modified before accessing the data. A user friendly database management system cannot be established via network model. Implementation of network database: Network database is implemented in: Digital Equipment Corporation DBMS-10 Digital Equipment Corporation DBMS-20 RDM Embedded Turbo IMAGE Univac DMS-1100 etc. Relational database (1980s present): Relational database model was proposed by E.F. Codd. After the hierarchical and network model, the birth of this model was huge step ahead. It allows the entities to be related through a common attribute. So in order to relate two tables (entities), they simply need to have a common attribute. In the tables there are primary keys and alternative keys. Primary keys form a relation with the alternative keys. This property makes this model extremely flexible. Thus using relational database ample information can be stored using small tables. The accessing of data is also very efficient. The user only has to enter a query, and the application provides the user with the asked information. Relational databases are established using a computer language, Structured Query Language (SQL). This language forms the basis of all the database applications available today, from Access to Oracle. Advantages: Relational database supports mathematical set of operations like union, intersection, difference and Cartesian product. It also supports select, project, relational join and division operations. Relational database uses normalization structure which helps to achieve data independence more easily. Security control can also be implemented more effectively by imposing an authorization control on the sensitive attributes present in a table. Relational database uses a language which is easy and human readable. Disadvantages: The response to a query becomes time-consuming and inefficient if the number of tables between which the relationships are established increases. Implementation of Relational Database: Oracle Microsoft IBM My SQL PostgreSQL SQLite Object-oriented database (1990s present): Object oriented database management system is that database system in which the data or information is presented in the form of objects, much like in object-oriented programming language. Furthermore, object oriented DBMS also facilitate the user by offering transaction support, language for various queries, and indexing options. Also, these database systems have the ability to handle data efficiently over multiple servers. Unlike relational database, object-oriented database works in the framework of real programming languages like JAVA or C++. Advantages: If there are complex (many-to-many) relationships between the entities, the object-oriented database handles them much faster than any of the above discussed database models. Navigation through the data is much easier. Objects do not require assembly or disassembly hence saving the coding and execution time. Disadvantages: Lower efficiency level when data or relationships are simple. Data can be accessible via specific language using a particular API which is not the case in relational databases. Object-relational database (1990s present): Defined in simple terms, an object relational database management system displays a modified object-oriented user-display over the already implemented relational database management system. When various software interact with this modified-database management system, they will customarily operate in a manner such that the data is assumed to be saved as objects. The basic working of this database management system is that it translates the useful data into organized tables, distributed in rows and columns, and from then onwards, it manages data the same way as done in a relational database system. Similarly, when the data is to be accessed by the user, it is again translated from processed to complex form. Advantages: Data remains encapsulated in object-relational database. Concept of inheritance and polymorphism can also be implemented in this database. Disadvantages: Object relational database is complex. Proponents of relational approach believe simplicity and purity of relational model are lost. It is costly as well. Web enabled database (1990s present): Web enabled database simply put a database with a web-based interface. This implies that there can be a separation of concerns; namely, the web designer does not need to know the details about the DBs underlying design. Similarly, the DB designer needs to concern himself with the DBs web interface. A web enabled database uses three layers to function: a presentation layer, a middle layer and the database layer. Advantages: A web-enabled database allows users to get the information they need from a central repository on demand. The database is easy and simple to use. The data accessibility is easy via web-enabled database. Disadvantages: Main disadvantage is that it can be hacked easily. Web enabled databases support the full range of DB operations, but in order to make them easy to use, they must be dumped down.

Essay --

Abraham Lincoln's election in 1860 brought a climax the long debate about the powers of the federal and the state governments, bringing about the Civil War. Though the war itself was long and rough, it didn’t match the problems of the reconstruction of the south. Newly freed African Americans had high hopes for full equality with the 13th, 14th and 15th amendments but because of the Southern white resistance and the withdrawal of supervision, it brought about even more racism by creating segregation and putting them back on plantations, increasing the whites hate and violence. War and Reconstruction changed the social, political and economic landscape in America with the creation of the black codes, racial groups such as KKK, and Civil Rights acts. As soon as the former slave had been freed their freedom was taken away by black codes, restricting most of their newfound rights and bringing back the idea of southern slavery. This changed the social structure because instead of creating equality after the war between African Americans and Whites, it brought back what the Civil War tri...

Biological oxygen demand (BOD) of water sample analysis Essay

Qualitative data: – Collected sample was very murky – The first end point colour was of a yellow colour, perhaps not light enough – Addition of starch indicator produced a grey-black solution; perhaps did not add enough indicator, however this did not pose as a problem – There was one occasion where I suspected to have added too much sodium thiosulphate, however the second trial indicated that I did not go past the end point too much Calculations To calculate the dissolved oxygen content (mg/dm ³ or ppm), we must first determine the number of mols of thiosulphate from the mean titrated volume of both samples. In this case, we will use sample A. The Winkler method indicates that the relationship between the amount of oxygen and thiosulphate is a four to one ratio. Therefore, we will divide the number of mols of thiosulphate by four to get the number of mols of oxygen. Then we convert this to milligrams per dm ³ first by multiplying by 20 to arrive with the number of mols present in 1dm ³ (because the pond water sample used was 50cm ³). Then we multiply that number by 32 (molecular mass of oxygen) to attain the number of grams of oxygen. Then finally, the number is multiplied by 1000 to be converted into milligrams. The biological oxygen demand (BOD) would therefore be the difference between the DO of sample A and sample B.

The #1 Left-Handed Scholarship

The #1 Left-Handed Scholarship SAT / ACT Prep Online Guides and Tips You’ve struggled all your life with scissors. You felt distinctly discriminated against during handwriting classes in grade school. And shaking hands feels downright unnatural. In short, you’ve suffered. And everyone knows that for every challenge out there, there’s a college scholarship to reward those who have struggled through it. Read on to hear about scholarships for you long-suffering lefties. Unique Scholarships for Unique People Did you know that one of the top search terms for scholarships is â€Å"left handed scholarships†? There is certainly a lot of demand, and many students have heard rumors of scholarships that will reward them for interesting physical attributes that they were born with. In fact, there are several scholarships out there for tall people, short people, fat people, healthy people, disabled people, and people who are visually impaired. And it’s true – there’s also a scholarship out there for you lefties! Congratulations! But let me emphasize that: there is A scholarship out there for you lefties. As in singular. One. And it’s from a college you’ve probably never heard of. You’re Just Not That Special Just kidding. You are special. Really. â€Å"But why only one?!† I can hear you shouting despairingly. I hate to be the bearer of bad news, but left-handed people are just not that special. The government doesn't consider left-handed people to be handicapped. Left-handed people haven't really suffered in any significant way. And they haven’t been discriminated against apart from in the relatively minor ways mentioned at the beginning of this article. In fact, about 10percent of the population is left-handed. There are approximately 700 million of you in the world. I’ll repeat: You are just not that special. (At least, not because of your dominant hand. Otherwise, you're a snowflake! Promise!) The good news is now that you know this, you can move on and start finding better scholarships. If you're determined to get an unusual scholarship, check out our list. There are alsothousands of scholarships out there and you are most likely qualified for at least some of them already, and others you can work to get qualified for. In short, the sooner you stop looking for left-handed scholarships, the better. The Only Left-Handed Scholarship But in case you're not convinced that you should seek money elsewhere, read on to hear about the only scholarship in the country for left-handed people. The Frederick and Mary F. Beckley Scholarship is awarded to one or two left-handed students each year at Juniata College in Huntingdon, Pennsylvania. Never heard of Juniata? According to a press release on their web site, this is quite common. Many students only learn about the college when they are looking for a left-handed scholarship. In case you would like to learn more, Juniata is a quite strong liberal arts college with about 1,600 students. In addition to offering the country’s only left-handed scholarship, they are unique for having â€Å"Programs of Emphasis† instead of majors, a very eco-friendly campus, and accomplished men’s and women’s Division III volleyball teams. They also host some fun annual events, including a Pig Roast and the Mr. Juniata Pageant. So How Did This Scholarship Come Into Being? Back in 1919, students Frederick Beckley and Mary Francis were paired together in their tennis class because the coach thought that left-handed people couldn’t play tennis as well as the other students. Though they ended up married because of this, Frederick and Mary apparently took the discriminative act to heart and set out to help future generations of Juniata students who might also be unfairly treated because of their unusual dominant hands. The final question on the Juniata’s financial aid questionnaire asks if students are right or left-handed, but students who choose the â€Å"left-handed† option don’t have to prove it. From this, demonstrated financial need, and academic record at the college (the award is only for sophomores and above), a few students are chosen every year for the award. Once students receive the scholarship, they continue to receive the scholarship yearly until they graduate. In case it isn’t obvious, you cannot receive this scholarship unless you attend Juniata College. And seeing as there is no application process, even if you do choose to attend Juniata College to be awarded for your left-handedness, you can’t do much to ensure you get this scholarship except do well academically.

Free Essays on Understanding Islam

This paper is about the book Understanding Islam written by Thomas W. Lippman. The book explains the basics beliefs and practices, Muhammad, the Koran, Law and Government, and Islam today. I chose to discuss three main themes, Zakat, the alms-tax, law and government, and the role of women in Islam. The first theme is Zakat, one of the five pillars of faith, stands for the alms-tax. The alms-tax is a mandatory donation to charity every Muslim must make. In the Islamic religion they strongly believe that the rich should give to the less fortunate. This is stated in the Koran; however the Koran does not specify how much should be given. The most common donation expected of a Muslim is 2.5 percent of the amount of cash and individual holds in savings or investments for a year. I think the Zakat is a good concept to have in one’s religion. It’s good because the money is actually going to the poor not the government or your church. Also 2.5 percent is not an unreasonable amount to ask for. A lot of people don’t give to charity and I think that more people should. If more people gave to charity then maybe the poor would have enough money or clothes to keep warm for the winter. The second theme is the law and government of Islam. One big difference between the United States and Islamic countries is the separation of church and state. This separation does not exist in Islamic countries because they believe their religion is also a way of life and should be the law of the land. Many of the laws come from prophets, such as Muhammad. An example of a law coming from Muhammad is, â€Å"Every Muslim has six obligations toward his fellow Muslim: he greets him whenever they meet; answers his call; wishes him well when he sneezes; visits him when he is ill; follows in his funeral when he dies; and wishes for him what he wishes for himself. These are some of the kinds of laws they have. Also they have rules for theft, murder and adu...

Career dilemma Essay Example | Topics and Well Written Essays - 750 words

Career dilemma - Essay Example Here the focus of discussion will be the ethical dilemma faced by psychologist while pursuing forensics as a career with special emphasis on their dual behavior, multiple relationships, and conflict of interests. Dual roles: A psychologist is a person that reads and understands a human mind. A forensic psychologist, however, has to perform dual functions i.e. as a therapist as well as the evaluator of the issue for legal documentation associated with a particular criminal presented at the court. The ethical dilemma associated with the dual role of a forensic psychologist is to maintain the confidentiality of the data. Acting as a therapist, a psychologist has to make sure that what ever is being told to him by the criminal should not be leaked out anywhere to any other party, and the information should only be used for legal documentation or for proving the criminal’s crime or innocence. According to Cornin (2006) an important ethical dilemma which is not concerned by the psyc hologists is the appropriate filing and use of tests when acting as a therapist. Moreover, psychologists while providing legal services, or acting as an evaluator, do not tend to evaluate the facts objectively as there exists a lack of communication and difficulty in conducting interviews with the third party. Multiple relationships: According to Moore (2011), conflicting relationships is one of the ethical dilemmas faced by forensic psychologists while practicing their job. These conflicting relationships occur in case a therapist develops some emotional feelings with any of his patients and might not be willing to treat patients in some other hospitals. However, this occurs when the therapists prefers to treat patients they know personally, as it requires less counseling as compared to treating the person they don’t know. In addition to this, another type of conflicting relationship occurs between the attorney and a psychologist. He may be forced to provide testimony and de clare the case of a particular person that is coherent with the success of a particular case in the court. This gives rise to the development of adverse and conflicting relationship of psychologists with the parties they deal on daily basis. According to Weinberger and Sreenivasan (1994), sometimes in prison, forensic psychologists are forced to do the tasks that are not related to their area of expertise. In case a prison is less staffed and they need to have a staff for security, it is quite possible that forensic psychologists are asked to perform such duties, which not only lead to the conflicting roles but also to the development of conflicting relationships with the prison staff. Conflict of interests: Forensic psychologist often confront with a conflict of interest. According to a research it is pointed out that forensic psychologists are often reluctant to treat their immediate relatives because their interests do not coincide. They know very well the pros and cons of antici pated therapist-patient relationship, which is why they feel reluctant in treating their professional and personal contacts. Similarly another important thing being pointed out is that while performing dual roles, often they tend to maintain the confidentiality so that the rights of the patients are not violated, leading to the conflicting interests between a therapist (or evaluator) and a patient. Conclusion: To

The major differences between the exoteric and esoteric path of Islam Essay

The major differences between the exoteric and esoteric path of Islam - Essay Example The exoteric path in contemporary Islam is composed of moderates and outnumbers the esoteric path of the radicals but still stands hijacked by nascent Islamic radicalism. Islam is typically perceived as one, whole and uniformly practiced religion but reality belies this simplified disposition. The paths of exoteric and esoteric Islam are well differentiated and this paper seeks to discuss the major differences between both. The largest difference between the exoteric Muslims and the esoteric Muslims is their attitude towards the propagation of religion. The esoteric Muslims see Islam as the ultimate solution for mankind and believe that it their responsibility to enforce Islam around the globe. Such quarters see Islam as the final solution for every problem that mankind faces ranging from emotional problems to population control. Sayyid Qutb, one of the founding fathers of modern radical Islam argues in his text Milestones (Qutb 57): â€Å"... annihilate all those political and mate rial powers which stand between people and Islam ...† In contrast, the original teachings of Islam are far more peaceful and refrains the believer from imposing his version of religion on the other person, whether Muslim or non Muslim. The Prophet of Islam was a staunch believer in religious pluralism including within Islamic realms. The Prophet of Islam, Muhammad, has been quoted as saying (Ernst 1045): â€Å"Difference of opinion is a mercy for my community.† Additionally, religious pluralism has been favored in the sacred text of Islam, the Quran. The Quran’s second chapter, Al Baqra, declares openly that the believers are not allowed to force other people into their religious fold. Islam has historically relied on preaching through peaceful means including open interaction with non Muslims. The earliest traditions from Islam, including the time when early Muslims were being prosecuted in Makkah, show that forced conversions and the imposition of religious doc trine on other religions was not allowed. The same can be said of the times when the Muslims were in power and had taken control of large swaths of the globe. The reign of Umar is mentionable in this regard. In around a decade Umar was able to expand the Islamic frontiers manifold through armed conflict but again Islam was not imposed on the conquered people (Ahmed 34). Instead, Islam was spread in most of the conquered areas through open interaction with the non Muslims. Even with the existence of evidence to the contrary, today’s radical Islamists are bent upon furthering Islam through violent means. A major problem that Islam faces like other major religions is the loss in translation. Islam was originally revealed in the Arabian Peninsula and the medium of communication and instruction remained Arabic. The Prophet Muhammad was Arab and was not instructed in other languages, so his entire set of instructions for Islam has been preserved in Arabic. Similarly, the Quran was revealed and the scribed in Arabic too. There were initially no problems as to the use of Arabic since the early converts and most of the converts in the Prophet’s own lifetime were Arabs. However, as the Islamic empire began to spread under the Rightly Guided Caliphs, the need for taking up other languages became apparent. It was felt that translating massive works of Quran and Hadith into other languages would abrade the meanings of the original texts. In an effort to

Lieutenant Calley Essay Example for Free

Lieutenant Calley Essay There is a big difference between known facts and the reality especially when it comes to military matters. There is a definite chain of command in place and in most cases soldiers do not do their own bidding but have to obey orders from above. The case of Lieutenant William Calley in the My Lai Massacre is one of the cases that expose the kind of leadership that we have in our military which comes at the backdrop of many public outcry against such cowboy actions. To many civilians, this is seen as a frame where someone has to take the fall and this person is usually down in the chain of command. The interesting thing is that in these cases, there is no evidences to prove who actually gives command for execution of orders that are detrimental to human rights. Lieutenant Calley was an average person in education and military service and therefore there was nothing extra ordinary about him. Many of the fellow soldiers in his troop seemed to distance themselves from him since the media had found a perfect example to portray what was happening in Vietnam (Collins Williams, 2000). What he did was ethically and morally wrong but he alleges that a command had come from above and he was simply following orders from above (Allyne 2000). His character here comes out as someone who follows orders and is obedient although we cannot rule out the opposite. The in Vietnam was very unpopular and not many people supported it and looking at issue from sides, the case and evidence was going against the lieutenant. Soldiers are known to be people of high integrity and who regard morality highly and therefore there must have been other compelling external factors that caused him to call for the massacre. Family and friends had a different opinion on his character and mental sanity. They regarded him as an average boy who was incapable of committing the atrocities in Vietnam. Looking at his background, there was a lot that was happening and some of it might be evidence enough to suggest that it clouded and interfered with his actions. Calley’s parents were not doing well health wise with both of them suffering from diseases that are associated with old ages. diagnosed with a terminal form of cancer and his father suffered from health complications due to diabetes. Human psychology is very complex and the way people react to situations differently and the happenings at home might have led to mental instability. The environment in the war front exerts a lot of pressure on soldiers and added pressure from home or other external source is enough to reduce the credence of anyone in a position of leadership. Members of the public with knowledge of the case continue to have a negative a view of Lt. William Calley considering his role in My Lai massacre in Vietnam. The public’s feeling toward Lt. Calley is further influenced by the media coverage of his case since 1970s, especially considering that prosecution of the case was accusing of acting on the influence of senior decision makers in the military. The increase in the amount of information available to the public is aiding in the shift of public perception in favor of Calley. Indeed, the American people are coming to the understanding that yes, Calley was deeply involved in My Lai massacre, but he was not alone; those at their higher levels of the military’s decision making brogans who were never prosecuted. Despite the increase in the information available to the public, Calley is still regarded as a blood stained master minder of the massacre. This perception will only change if Calley himself tells the public of the My Lai story. As for the prosecutor, Lt. Calley was simply guilty. To critics, this form of incriminating stance was adopted by the prosecutor, based on the accounts which were issued to him by the Senior Army Personnel who were in control at the moment. To this effect, that Lt. Calley ordered the massacre in M y Lai is taken as the premise of the case, rather than the need to examine the chain of command under which Lt. Calley was acting and issuing orders. Many of soldiers that were in war at the time in Vietnam concur that the case of the massacre was not an isolated case but may have been one of the many happenings that are alleged to have taken place around that time. The situation on ground in a war zone is usually different from an ideal situation and therefore civilians are the worse people to judge military personnel. The happenings back at home might have interfered with his thinking which supports that he was acting on his own and not orders from above. It is therefore not easy to determine the basis upon which he used to instigate the massacre. References Allyne, W. (2002). A Look at the Vietnam Court Cases New York: McGraw Hill.

Synthesis And Characterization Of Strontium Ferrite Environmental Sciences Essay

Synthesis And Characterization Of Strontium Ferrite Environmental Sciences Essay Strontium ferrite is a ferromagnetic material and reported as having hexagonal magnetoplumbite type (M-type) structure. It is the most widely used permanent magnets throughout the world, which account for about 90wt% of the annual production of permanent magnets. In this study, the strontium ferrite is synthesized using sol-gel methods and the magnetic properties were analyzed. Chapter 1 gave introduction about the structure of M-type hexagonal strontium ferrite. Besides, some general magnetic properties will be discussed. Commercial applications of strontium ferrite would be discussed as well. Chapter 2 is all about the experimental details, including the synthetic techniques used for strontium ferrite, description of instrument used and procedures carried out. Chapter 3 concentrated on the results on magnetic susceptibility of hexagonal strontium ferrite. Comparison between strontium ferrite and cation-substituted strontium ferrite was made. Chapter 4 concluded the whole investigation of this study. Suggestions for future studies were also discussed. Better understanding of the properties and practical applications of strontium ferrite can be achieved through this study. ABSTRACT The properties of magnetoplumbite type (M-type) hexagonal strontium ferrite has been investigated. The attempt of substitution of cobalt(II) oxide and titanium(IV) oxide in order to produce a quaternary system of the type SrO-Fe2O3-XO where X represents the dopant cation was made. The synthesis is based on sol-gel method where ethylene glycol is the gel precursor. This technique was employed because it was found to be able to produce nanoparticles of cation substituted strontium ferrite. Moreover, sol-gel method can produce high yields of strontium ferrite particles. Overall, the magnetic properties were observed to be change after the cation substitution. Co(II)-Ti(IV) substitution in SrFe12O19 with different ratios were made in this study to investigate the effect of cation substitution in magnetic properties of strontium ferrite. Co(II)-Ti(IV) substitution in strontium ferrite with mole ratio of 0.4 showed the best magnetic properties that we desired for. The mass susceptibility where X = 0.4 was found to be increase sharply compared to the unsubstituted one. Except the cobalt titanium substitution with mole ratio of 0.4, other cation substitution ratios showed decrease in mass susceptibility which is not desirable. Therefore the cobalt-titanium substitution for SrCoxTixFe12-2xO19 with X = 0.4 is the best to improve magnetic properties of strontium ferrite for various commercial applications. REVIEW Strontium ferrite has been a subject of continuous interest and intensive study for several decades due to the fact that this compound has been the the most widely used permanent magnets, which account for about 90wt% of the annual production of permanent magnets since shortly after its discovery in the 1950s. Strontium hexaferrite, SrFe12O19, is a ferrimagnet and is also known as ceramic permanent magnet. When compared with alnico-magnets, strontium ferrite has high coercivity, moderate remenance, corrosion resistance and excellent chemical stability [5]. Iron(III) oxide (Fe2O3) is the principal components in SrFe12O19 which gives rise to its magnetic properties. Within the five different crystallographic sites of strontium ferrite, the iron ions are coupled antiferromagnetically. Due to its high magnetocrystalline anisotropy field in its structure, SrFe12O19 exhibits high saturation magnetization and high coercivity [1]. The high magnetic permeability in strontium ferrite enables i t to store strong magnetic fields, which is stronger than iron. Strontium ferrite is often produced as nanoscale size powder, which can be sintered into solid cores. Strontium ferrite has been used for several important industrial applications, such as permanent magnets, microwave devices and high density perpendicular recording media, with proper doping in order to improve properties of strontium ferrite [1]. SrFe12O19 has also been investigated as a medium for magnetic recording and magneto-optical recording and for long (millimetre)-wave devices [2]. Efforts have made to the development of novel synthetic methods which facilitate the production of fine hexagonal ferrite particles and to possible ways of reducing their high intrinsic magnetocrystalline anisotropy. The objective in this study was to attempt the synthesis of cation substituted M-type hexagonal ferrite SrCoxTixFe12-2xO19 using the sol-gel method. The sol-gel method has been used widely to produce fine particles of a variety of oxides. The effect of doping strontium ferrite with cobalt (II) and titanium (IV) oxides to produce quaternary systems of SrO-Fe2O3-XO, where X represents the dopant cation would be tested. The fine particles of cation substituted ferrite produced by using sol-gel technique is desirable because the grain size of the materials used in magnetic recording is the main factor determining the level of background noise at low density. Magnetic properties of strontium ferrite would be focus in this study. Magnetic susceptibility balance would be used to determine the mass susceptibility for both strontium ferrite and cation-substituted strontium ferrite produced using the sol-gel method. The mass susceptibilities of the samples were compared to determine the optimum amount of cation needed to dope to ferrite to give the best magnetic behaviour. CRYSTAL STRUCTURE OF M-TYPE HEXAGONAL SrFe12O19 According to crystalline structure, hexaferrite can be classified into four types, these include M, W, Y and Z types hexaferrites which correspond to (SrO + MeO):Fe2O3 ratios of 1:6, 3:8, 4:6 and 5:12 respectively. SrFe12O19 is classified as M-type hexaferrite. The hexagonal SrFe12O19 was first prepared by Adelsk ¨old in 1938 [2]. He also confirmed that the crystal structure of this compound to be iso-structural with the naturally occurring ferrite mineral magnetoplumbite, and therefore it has the M-type structure. Later structural refinements for strontium hexaferrite have confirmed his determination [2]. Strontium ferrite is classified as hexagonal ferrite. It is denoted as having the space group P63/mmc. According to the research made by Kimura et al, the lattice parameters measured are found to be: a = 0.588 36nm and c = 2.303 76nm at room temperature [2]. As shown for M-type hexaferrite BaFe12O19 in Fig. 1.1, the crystalline structures of different types of hexaferrites are remarkably complex. The unit cell contains ten oxygen layers. A unit cell is sequentially constructed for four blocks, they are S (spinel), R (hexagonal), S* and R*. The S and R blocks have equivalent atomic arrangements and are rotated around the c-axis at 180 ° with respect to S* and R* blocks. R or R* block consists of three O2à ¢Ã‹â€ Ã¢â‚¬â„¢Ã‚  layers while S or S* block contains two O2à ¢Ã‹â€ Ã¢â‚¬â„¢Ã‚  layers; with one oxygen site in the middle layer substituted by a Ba2+  ion [16]. The structure of strontium ferrite is similar to that of barium ferrite, by just substituting the barium ion with strontium ion. Fig.  1.1:  Structure of barium hexaferrite Occasionally, a unit cell is comprises of two formula units. The unit cell consists of 64 ions per hexagonal unit cell, which are 2 strontium ions, 38 oxygen ions and 24 ferric ions. The structure of magnetoplumbite are made of a layer of hexagonal close packed arrangement of oxygen and strontium ions, which is sandwiched between two spinal blocks containing a cubic close-packed arrangement of oxygen atoms with iron atoms. The iron atoms are positioned at five interstitial crystallographically different cation sites of the close-packed layers, namely 4f1 (tetrahedral site, A sites), 12k, 4f2, 2a (octahedral sites, B sites) and 2b (trigonal bipyramidal site) [15]. The tetrahedral iron oxide is FeO4, octahedral iron oxide consists of six oxygen ions, which is FeO6, and the formula for trigonal bipyramidal iron oxide is FeO5. A schematic M-type structural representation and the five Fe3+ sites are shown in Fig. 1.2 by Collomb et al. [15]. Figure 1.2: The crystal structure sketch map of the hexagonal M-type phase and the five Fe sites with their surroundings are displayed. The 2b sites only occur in the same layer with strontium ion. 12k site is the octahedral site of S and R blocks. There are two tetrahedral (4f1) sites and one octahedral (2a) site in centre of S block. The two octahedral (4f2) sites are found in the R block, adjacent to the strontium-containing layer. The M-type structure of strontium ferrite gives rise to its magnetic properties. Cation substitution to strontium ferrite may give chances whereby altering the structure and thus influence the magnetic properties. MAGNETIC PROPERTIES OF M-TYPE HEXAGONAL SrFe12O19 Strontium hexaferrite is a ferrimagnetic material. Since the free electrons in SrFe12O19 are in close proximity and remain aligned even the external magnetic field have been removed, it is able to retain a permanent magnetic field and is recognized as ferrimagnetic material. In 1950s Gorter predicted that the iron ions at the trigonal bipyramidal (2b) and octahedral (2a, 12k) sites have their spin orientation antiparallel to that of the iron ions at the 4f sites [2]. The antiparallel 4f1 and 4f2 and parallel 2a, 12k and 2b sublattices form the ferrimagnetic structure. The magnetic ordering corresponding to the magnetoplumbite structure of hexagonal strontium ferrite is well illustrated in Fig. 1.3. In S block, the majority ÃŽÂ ±-sublattice consists of four octahedral ions and the minority ÃŽÂ ²-sublattice contains two tetrahedral ions whereas R block contributes three octahedral ions and one trigonal ion to the majority sublattice and two octahedral ions to the minority sublattice. Figure 1.3: The schematic structure (left) of the SrFe12O19 with Gorters magnetic ordering (middle) along the c-axis. The large open circles are oxygen ions, the large broken circles are Sr ions; small circles with a cross inside represent Fe ions at 12k, small circles containing a filled circle inside represent Fe ions at 4f2, small unfilled circles represent Fe ions at 4f1, filled small circles represent Fe ions at 2a and small circles with a unfilled circle inside represent Fe ions at 2b. The magnetic structure suggested by Gorter is shown on the right, where the arrows represent the direction of spin polarization. From Fig. 1.3, we can summarizes the sites of Fe(III) ions corresponding to the spin direction, as in Table 1.1. Site Coordination Occupancy Direction of spin polarization 12k Octahedral 12 Up 2a Octahedral 2 Up 2b Trigonal Bypiramidal 2 Up 4f1 Tetrahedral 4 Down 4f2 Octahedral 4 Down Table 1.1: Fe(III) ion sites in M-type hexagonal ferrite Hysteresis Loop The magnetic properties of strontium ferrite can be examined through hysteresis loops. Hysteresis loop can be measured using instruments such as Vibrating Sample Magnetometer (VSM) and SQUID Magnetometry Measurements. When a magnetic material is placed in a magnetic field, the flux density (B) would lags behind the magnetizing force (H) that causes it, and this form hysteresis loop. From a hysteresis loop, we can identify the magnetic properties of the material, they are saturation magnetization, remanence or also known as remnant magnetization, and coercivity. A typical hysteresis loop is well illustrated in Fig. 1.4. Figure 1.4: Typical hysteresis loop (B-H curve) Initially, there is no applied magnetic field and it is known as unmagnetized state. After magnetic field is applied, it causes alignment. Until maximum magnetizing force applied, maximum flux density achieved at the same time and this phenomenon is known as saturation magnetization. At this point, the maximum number of spin has mobilized. Saturation magnetization is defined as the maximum possible magnetisation of a material. It is also a measure of strongest magnetic field a magnet can produce. The unit of saturation magnetization is in amperes per meter. Strontium ferrite is having high saturation magnetization at which it can store high amount of magnetizing force. As the magnetizing force being slowly removed, the alignment stays at the point where H = 0, this is known as remnant magnetization. Remnant magnetization is the magnetization left in a permanent magnet after an external magnetic field is removed. When a magnet is magnetized, it has remanence. It is usually measured in unit Tesla. Strong permanent magnet such as strontium ferrite has high remnant magnetization which means the high amount of magnetic force remains in it even after the magnetizing force is removed. As form Fig. 1.4, negative magnetic field is applied to demagnetize the permanent magnet. When the flux density (B) = 0, there is no magnetizing force remain in the magnet and the negative H needed to demagnetize the magnet is known as coercivity. Negative H is the magnetic field applied in opposite direction. Coercivity is measured in unit amperes per meter. Due to its high uniaxial magnetocrystalline anisotropy with an easy axis of magnetization along the hexagonal c-axis in the structure, SrFe12O19 has high coercivity. Anisotropy is directional or orientational effects in crystal structure of materials which can provide better magnetic performance along certain preferred axis. Therefore, we need to apply high negative magnetizing force to demagnetize strontium ferrite. Attempts have to be made to lower down the coercivity of strontium ferrite for usage. Units in Magnetism The units used in magnetism can be divided mainly into two categories, SI system and c.g.s system. The conversion table shown in Table 1.2 is to clarify the magnetism formulas in both SI and c.g.s systems and the conversion factors between them.

B. Teh et.al [3] on strontium ferrite, strontium ferrite was found to exhibit photoluminescence behavior. When a sample of strontium ferrite is excited at a certain wavelength, highest intensity of photoluminescence emission peaks was obtained. The ability of strontium ferrite to photoluminesce could be due to the oxygen vacancies in their lattice structure. The oxygen vacancies are assumed to cause the particles to exhibit photoluminescence behavior by acting as traps for mobile excitation. The oxygen vacancies have effective +2 charges, making them powerful electron capture centers. Valence electron would gain sufficient energy to jump from the valence band to the conduction band and leaving a gap known as hole during excitation. F-centers, which is the region where contain high amount of electrons would formed when the excited electrons being trapped in oxygen vacancies. These rich electron centers would lead to emission of luminescence when the holes and electrons recombine. 1.5 SYNTHESIS ROUTE OF SrFe12O19 The processing routes used for synthesis of strontium ferrite affect its properties much. Traditionally, this ferrite powder is synthesized by a mixed oxide ceramic method, which involves the solid-state reaction between SrCO3 and Fe2O3 at a high calcination temperature (about 1300 °C). However, uncontrolled particle morphology, larger particle size and agglomerates would be the biggest disadvantages of this technique. Besides, contamination would be introduced to the sample while subsequent milling of the calcined ferrite powder and this would affect the magnetic properties become less desirable. Therefore, the narrowed particle size distribution, refined particle size and minimal particle agglomeration has been the main concern during the synthesis of strontium ferrite. In order to improve the magnetic properties, numerous nonconventional soft synthetic routes have been carried out, including sol-gel synthesis [3], hydrothermal reaction [6], co-precipitation [7], citric acid method [8] and microemulsion processing [10]. In this study, the synthesis of strontium ferrite employed the sol-gel technique. It is a wet chemical route employing ethylene glycol as gel precursor. Sol-gel technique is the technique of using chemical substances which have high solubility in organic solvents to synthesize precursor compounds. The compounds are easily transformed into hydrated oxides on hydrolysis. The metal alkoxides formed can be removed easily using hydrolysis and thermal treatment and therefore results in hydrated oxides which are highly purify. Sol-gel method is used in this study because of its many advantages. Sol-gel technique is able to produce homogeneous nanosized crystallites. This method is tend to give shaped materials directly from a solution without passing through the powder processing and the fact that the annealing temperature is very low compared with other conventional technology. The crystalline size and properties of the ferrite produced are largely affected by calcinations temperature [3]. Sol gel method has the advantage that the crystal growth of particles is easier to control by varying the heat treatment [11]. It was reported that at 500ËÅ ¡C it produced only maghemite, ÃŽÂ ³-Fe2O3. A mixed product of magnetic ÃŽÂ ±-Fe2O3 and M-type SrFe12O19 were obtained at 600ËÅ ¡C. As the calcination temperature increase to 800ËÅ ¡C and above, there are only M-type SrFe12O19 phase was observed. Sol-gel synthesis is able to produce high yields of SrFe12O19 nanoparticles. It is also able to prod uce nanocrystallite of cation substituted SrFe12O19. Nanoparticle size of strontium ferrite is desirable and aimed to synthesize because nanoparticles tend to give better magnetic properties. Nanoparticles give few magnetic domains, probably single domain. Single domain tends to give higher magnetic induction because there are no oppose magnetic domain. Single domain aligns in one direction only. These properties are ideal for the making of permanent magnet. 1.6 CATION SUBSTITUTION IN SrFe12O19 In order to improve the magnetic properties of strontium ferrite, many studies have been carried out. One of them is cation substitution in strontium ferrite. Rare earth and other metal cations are used for substitution for strontium and iron respectively [5]. The pair doping of SrFe12O19 such as a La-Co pair to replace a Sr-Fe pair has been tested [14]. The doping, or known as cation substitution, is aim to improve the magnetic properties of strontium ferrite. Cation substitution results in structural changes in strontium ferrite. As the physical properties of ferrite change, the magnetic properties would be affected due to the fact that magnetic properties are determined by the arrangement of iron ions in crystal structure. In this study, Co-Ti pair will be doped to the strontium ferrite. Cobalt titanium substitution will produce a quaternary system of the type SrO-Fe2O3-AO where A represents the dopant cation.The cobalt titanium substitution gives rise to the new formula, SrCoxTix Fe12-2xO19 where X is the number of mole of cation substituted in. 1.7 Commercial Applications Strontium ferrite is widely used as permanent magnet because it has direction of easy magnetization and the hexagonal c-axis which are perpendicular to the plane of the plate. The properties that are desirable in using as permanent magnet include high saturation magnetization, high remnant magnetization, high coercivity, high Curie temperature and high magnetocrystalline anisotropy. Besides, SrFe12O19 is also commonly used in high-density data storage magnetic recording media. Nanoparticles of SrFe12O19 with single domain and low coercivity are crucial in used for magnetic recording media. M-type strontium ferrite nanoparticles have attracted much attention due to their good frequency characteristic, low noise, high output, in particular, excellent high frequency characteristic and wide dynamic frequency range [4]. There are two types of recording medium, namely particulates and thin films. Tape and floppy is categorized in particulate and hard drive is belongs to thin film. Information is stored by magnetizing material. The recording head can apply magnetic field (H) and align domains to magnetize the medium. It can also detect a change in the magnetization of the medium. Magnetic recording media prefers high saturation magnetization; make it to store as much information. High value of remnant magnetization is required in recording media to make sure that all m aterials stored in the hard disk still remained even the power supply (applied magnetic field) is switched off. Low coercivity is important in magnetic recording media. When the positive magnetic field is applied, this charging manages the medium to store data. On the other hand, negative magnetic field applied to retrieve back the data, this is called discharges. Therefore, less current is needed to retrieve the data in the low coercivity medium. As a result, less heat generated and this saves the electricity. In general, strontium ferrite has high value of uniaxial anisotropy field, high coercive force and high saturation magnetization. The high coercivity of strontium ferrite has to be lowered down and saturation magnetization has to be simultaneously increased if it is to be useful for magnetic recording purposes. It has been reported that the substitution of cations such as Co(II) for the ion Fe(III) in strontium ferrite has lowered the coercive force. Therefore, many studies were carried out to achieve better magnetic properties of strontium ferrite for commercial applications. CHAPTER 2: EXPERIMENTAL Sample Preparation Synthesis of M-type SrFe12O19 Synthesis of Cation Substituted SrFe12O19 Sample Characterization Magnetic Susceptibility Balance MK1 2.1 Sample Preparation 2.1.1 Synthesis of M-type SrFe12O19 The sol-gel technique was used to synthesize M-type SrFe12O19 whereby the ethylene glycol acts as gel precursor. The starting materials, strontium nitrate, Sr(NO3)2 and iron(III) nitrate-9-hydrates, Fe(NO3)3 ·9H2O were used due to their high solubility in ethylene glycol. Calculation below was made to determine the weight of materials needed to be used. Relative Molecular Mass of materials: Strontium nitrate, Sr(NO3)2 = 211.63 g/mol Iron(III) nitrate-9-hydrates, Fe(NO3)3 ·9H2O = 404 g/mol (Note: All answers have to be converted into 3 significant figures.) No. of mol of 1 g Sr(NO3)2 = Mass of Sr(NO3)2 RMM of Sr(NO3)2 = 1g 211.63g/mol = 4.725210-3 mol Sr : Fe = 1 : 12 No. of mol of Fe(NO3)3 ·9H2O needed = 4.725210-3 mol x 12 = 5.670210-2 mol Mass of Fe(NO3)3 ·9H2O needed = No. of mol of Fe(NO3)3 ·9H2O needed x RMM of Fe(NO3)3 ·9H2O = 5.670210-2 mol x 404g/mol = 22.9 g From the calculation, 1g of strontium nitrate and 22.9g of iron(III) nitrate-9-hydrates were needed in the synthesis and were weighted. Strontium nitrate would provided 1 mol of strontium ions and iron(III) nitrate-9-hydrates would provided 12 mol of iron ions in the synthesis of strontium ferrite, which matched the molecular formula of SrFe12O19. The strontium nitrate and iron(III) nitrate-9-hydrates were readily dissolved in ethylene glycol with slight heat applied due to their high solubility in it. The mixture was heated slightly and stirred with a magnetic bar until the mixture was fully dissolved. The resultant solution is in transparent reddish color. The magnetic stirring bar was removed. The mixture was heated to 100 °C and it would slowly transform into a gel form. The gel was dried with continuous heating at 100 °C for 3 hours. The dried gel was then transferred to a crucible to remove traces of organic precursor. A mixture of metal oxides in dispersed nanoclusters form was obtained. The dried gel was then annealed in a furnace at 800 °C for 3 days with extensive ground with a pestle in a mortar after annealed at interval of each day. 2.1.2 Synthesis of Cation Substituted SrFe12O19 Cation substituted strontium ferrite was synthesized by using cobalt(II) ions and titanium(IV) ions to substitute the iron ions in M-type hexagonal strontium ferrite. The substitution of Co(II) and Ti(IV) gives the compound a new molecular formula, which is SrCoxTixFe12-2xO19 where the x denoted different ratios. In the synthesis of cation substituted SrFe12O19, the ratios of cations used, x, is in between 0.2 to 6.0 (0.2 à ¢Ã¢â‚¬ °Ã‚ ¤ x à ¢Ã¢â‚¬ °Ã‚ ¤ 6.0), where x = 0.2, 0.4, 0.6, 0.8, 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0. The same method described in section 2.1.1 was used for the synthesis, by only adding two new starting materials, which are the cobalt(II) nitrate and titanium(IV) ethoxide to give the Co2+ and Ti4+ cations. Calculation as described below was made to calculate the weight of materials needed respectively. Relative Molecular Mass of materials: Strontium nitrate, Sr(NO3)2 = 211.63 g/mol Iron(III) nitrate-9-hydrates, Fe(NO3)3 ·9H2O = 404 g/mol Cobalt(II) nitrate, Co(NO3)2.6H2O = 291.04 g/mol Titanium(IV) ethoxide, Ti(CC2H5)4 = 228.11 g/mol (Note: All answers have to be converted into 3 significant figures.) Example used for the calculation: SrCo0.2Ti0.2Fe11.6O19, x= 0.2 No. of mol of 1 g Ti(CC2H5)4 = Mass of Ti(CC2H5)4 RMM of Ti(CC2H5)4 = 1g 228.11g/mol = 4.383810-3 mol 0.2 mol of Ti needed 1 mol of Sr. 4.383810-3 mol of Ti needed (4.383810-3 mol x 1) mol of Sr. 0.2 Therefore, 0.021919 mol of Sr is needed. Mass of Sr(NO3)2 needed = 0.021919mol x 211.63 g/mol = 4.64 g 0.2 mol of Ti needed 11.6 mol of Fe. 4.383810-3 mol of Ti needed (4.383810-3 mol x 11.6) mol of Sr. 0.2 Therefore, 0.25426 mol of Fe is needed. Mass of Fe(NO3)3 ·9H2O needed = 0.25426mol x 404g/mol = 103 g Mass of Co(NO3)2.6H2O needed = 4.383810-3 mol x 291.04g/mol = 1.28 g The calculation above were used to calculate the weight of starting materials needed for other cation ratios, x for 0.4, 0.6, 0.8, 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 respectively as well. The weight needed for each material was tabulated in Table 2.1. x Weight of materials needed (g) Sr(NO3)2 Fe(NO3)3 ·9H2O Co(NO3)2.6H2O 0.2 4.64 103 1.28 0.4 2.32 51.4 1.28 0.6 1.55 31.9 1.28 0.8 1.11 23.0 1.28 1.0 0.93 17.7 1.28 2.0 0.46 7.08 1.28 3.0 0.31 3.54 1.28 4.0 0.23 1.77 1.28 5.0 0.19 0.71 1.28 6.0 0.15 0.00 1.28 Table 2.1: Weight of materials needed for synthesis of Co(II)-Ti(IV) substituted strontium ferrite For the series of different substitution ratios (x), the corresponding strontium nitrate, iron(III) nitrate-9-hydrates, cobalt(II) nitrate and titanium(IV) ethoxide were weighed and dissolved in 100ml ethylene glycol. The oxides obtained after ignition were then annealed in a furnace at 800 °C for 3 days with extensive ground with a pestle in a mortar after annealed at interval of each day. The preparation for strontium ferrite and cation substituted strontium ferrite is shown in Fig. 2.1 in flow chart array. Figure 2.1: Schematic diagram of the procedure for synthesis of strontium ferrite and cobalt-titanium substituted SrFe12O19. Sample Characterization Magnetic Susceptibility Balance MK1 The magnetic properties of strontium ferrite and cobalt-titanium substituted strontium ferrite produced by the method described above were examined using the Magnetic Susceptibility Balance MARK 1 (MK1) by Sherwood Scientific Ltd, England. The magnetic susceptibility balance apparatus was shown in Fig. 2.2. Figure 2.2: Magnetic Susceptibility Balance MK1 by Sherwood Scientific Ltd, England. The basic design principle of Magnetic Susceptibility Balance MK1 was shown in Figure 2.3. Magnetic Susceptibility Balance determines the magnetic properties by placing two couple of moving magnets with the beam in between where the stationary sample is ready to be measured. Basically, the possible deflection in the beam and the movement being made of a particular sample either solid or liquid could be observed in a balanced system which possesses a magnetic field. Meanwhile, the coil within the instrument is conducted with current required in order to make compensation of the magnetic force produced by the sample. Either paramagnetic or diamagnetic could be resolved in a plus or minus relatively on display with the aid of the direction that the beam swifts. Figure 2.3: Basic design principle of Magnetic Susceptibility Balance MK1 by Sherwood Scientific Ltd, England. Magnetic susceptibility is defined as when the magnetising field is applied to the sample, how much is the ratio of the intensity of magnetism induced by the sample in response to the magnetising field which it is subject. In this experiment, mass susceptibility was the main concern. Mass susceptibility, xg, is defines by the mathematical formula below: à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥g= à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥v/d Where d = density of substance à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥v is the volume susceptibility, calculated by using the formula: à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥v = I/
