Health Benefits of Seaweed Essay

Food is an important component of health because the body can receive more nutrients from it such as vegetables, fruits or seafood. In regards to seafood, we cannot forget to mention seaweed. The issue of health benefits of seaweed has grown in importance. In addition, scientist has proven that seaweed has the widest range of minerals. It is not only a good source of nutrients can prevent some diseases but also giving individual and natural beauty. Seaweed has many different types and colors and each type of seaweed has a unique nutrient composition. A study has confirmed that seaweed inherently benefits for health; it has many minerals which are available in the food people eat such as iron, calcium, B-vitamin or magnesium†¦ that can against lots of diseases. For example, seaweed is very high in lignans, which help the body prevent the chemical oestrogens that can cause breast cancer in woman. Additionally, magnesium has been shown that can reduce heart attack for people who has a high blood pressure. Moreover, seaweed is a rich source of fiber molecule align that can prevent constipation from our body. About B-vitamin folic acid, it reduces colon cancer. Or the folic acid, it has a role in protecting others important like prevent certain birth defects; including spina bifida and the chemical Homocysteine – cardiovascular disease and stroke†¦ Not only that, seaweed can cure stressful in humans with magnesium, pantothenic acid and riboflavin. Three of them are necessary for energy production. Seaweed is also a woman’s friend because it’s high in nutrients, low in calories that help them manage their weight in diet. Like McAdams said that seaweed is a food free weight because it’s virtually fat free, it just provide only 5 to 20 calories in a meal (Health benefits), so they don’t have to worry about weight gain and control body fat. In other hand to food supply, seaweed has vitamin which benefits for natural beauty. It improves the viscosity and elasticity of your skin. Besides that, it reacts with protein to form a gel that moisturizes skin and precludes wrinkles. Wrinkles are the enemy of women so they try to find the best solution to have smoother, more youthful skin in just 30 days. For your hair, seaweed has the effect of making your hair smoother, softer and lighter. The black-brown seaweed is called Arame, nourishes the scalp and hair follicles and makes your hair look healthier. So lots of companies have been producing many new products that made from seaweed. Basically, seaweed health benefits are undeniable. Seaweed is easy to make with food and it’s very popular for Asian, specially Japan and Korean. Overall, seaweeds are highly nutritious, like a book â€Å"Seaweed Beauty Guide† said: â€Å"It is a nature’s secret to balancing your metabolism, fighting disease, revitalizing body and mind. † (Cooksley 83) The findings of this research have shown that the benefits of seaweed are countless, that’s a reason why everyone should eat. The numbers of people in Europe, who discover and use seaweed, are recently increasing. Seaweed would be a â€Å"secret key† for a long and healthy life and your family.

State and Poem

Journal: â€Å"Sun in My Skin† Robert Johnson The poem â€Å"Sun in My Skin† is a poem that comprises of a Bahamian man who expresses a love for his Bahamian culture. He portrays what it truly means to be â€Å"Bahamian. Johnson shows love of his culture when he states â€Å"But in my brash vibrating arm the cowbell dances† Also he shows pride in our country considering the state we are in when he states â€Å"And when I go to banquets, the food don’t agree with me†.The main focus of the poem is how the writer exquisitely expresses his way of life and how being Bahamian makes him proud. Johnson feels as though being Bahamian is not all about being rich, but to stand up rightfully as people maintaining a peaceful and tranquil Bahama land. The poem also talks about â€Å"rich and cultivated† which means Johnson feels no matter what state, race or situation our country is in, nothing makes him less of a Bahamian. I feel as though the poem is a commemoration of our culture and way of life.How as people, we must fend for ourselves rightfully as â€Å"Bahamians†. I also feel that Johnson had a sense of excitement towards the poem; expressing himself effectively. Other significances are the sun which reflects on our beautiful Bahama land and the cowbells signify the love for our culture and the excitement it brings to the lives of many. The poem â€Å"Sun in My Skin† is one of the many poems that reflect on what it means to truly be Bahamian.

Organisational Behavior in Hospitality Industry Essay

Organisational Behavior in Hospitality Industry - Essay Example Therefore, it would not be wrong to assert that organisational behavior impacts employee loyalty and vice versa. The scope of this paper is to assess the positive or negative impact of organisational behavior upon employee relations and to what extent employment relations are flexible to adapt to the changing trends of service training and leadership. This paper describes a unique combination of how and why managers despite using supportive leadership vision remains unable to make effective usage of managerial control strategies to change, maintain or build a specific type of 'employee committed' culture and face challenges in the form of high turnover rate. Various factors that affect employee loyalty in the British hospitality workplaces in the context of national and private service sector patterns cannot ignore the fact that employment in service sector is subject to regulation in areas such as minimum wages, lack of pay and reward system, traditional managerial approach, gender issues etc. But beside regulations what matters, is the different economic, social, legal and political factors that create particular cultures and diverse employment systems to understand the context in which employee loyalty can be understood and measured. Despite the efforts to make employment relations in the British service industry from 'vulnerable' to 'secure', there is a difference when national service sector is compared with the private one. On one hand, employment policies and practices are responsible for conforming to the management-driven ungoverned individualism thesis which is based on cost-control, whereas on the other they reflect a more af filiated and liberal managerial approach within a customer-service attribute. It is not necessary to alienate employees, however they may trade off low pay for other compensations demonstrating enfranchised pragmatism. The employment relationship is based upon transactional, relational, and exploited recruitment. What is important in employee management is to realise that front-office or other hotel employees are different and they are subjected to a unique compelling task that trade unions face. Managers need to develop an attitude to measure their attempts in recruiting members and organise workplaces while understanding the nature of the common barriers between managers and employees. This help them to visualise what they do not share as commonly held assumptions of 'good' employment relations. This paper analyses the leadership and management style adopted in circumstances which escorts the managers to face challenges like employee shortage and lack of loyalty. The impact of Leadership on Employee Loyalty There was a time when managers used to deploy strict procedures and peer support while approaching bureaucratic managerial style. Contemporary management has no room for bureaucracy and prefer charismatic leadership, and when it comes to hospitality management, leadership does not require a simple set of traits to function but is more likely to be dependent upon a range of interacting elements that require genetically as well as culturally determined traits like attitudes towards employees, rational expectations, accent and emotions towards

It operates supermarket chains such as K-mart and Target; it also operates the largest Australian hardware chain of stores. It grew big and fast through a strategy of acquisitions with the latest being the Coles Group that was the second-largest retailer in the country after Woolworths Limited. In total, it is engaged in about nine different industries (Wesfarmers.com, n.d.). As a publicly-listed limited corporation, the Wesfarmers adheres strictly to the corporate governance principles and standards prescribed by government regulatory authorities. In addition, to further inspire investor confidence, it has also voluntarily adopted a Board of Directors code of conduct and a separate code of ethics and conduct for all its employees. It has likewise adopted a Whistleblowers policy to pro tect people who report on anomalies within the company. Overall, Wesfarmers has put into place safeguards such as risk management controls and is fully committed to transparency. In general, Wesfarmers is engaged in the retailing business, insurance, energy (its coal and mining operations to include gas and energy interests) and industrial products with minor interests in other industries such as corporate finance and sawmill operations. Wesfarmers is a notable exception in terms of its financial performance when conglomerates are now out of favour because it was able to grow at a 30% compound rate (Walsh, 2002:1) and transformed itself from a former farmers cooperative into a real business giant. Its mining operations is a major contributor to the local economy and provides nearly 50% of the electricity grid in the states south-west region (Richards,

Strategic Management for Smirnoff Assignment Example | Topics and Well Written Essays - 4000 words

Strategic Management for Smirnoff - Assignment Example Smirnoff is a brand of Vodka used in UK and is own and operated by British Company Diageo however, it has its roots in Moscow Russia. Smirnoff is now distributed in well over 130 countries with a network which is expanding and catering to the needs of different customers all over the world. Being an alcoholic drink, the overall external environment for this brand is relatively challenging considering the fact that many countries have banner alcoholic drinking. Issues like the underage selling, drunk driving and other strategic issues are considered as of significant importance. This is because these issues can actually affect the overall demand of the product. This report will look into the target market, value given by the company to its target market, a closer analysis of the internal as well as external environment including analysis of the industry as well as competition. This report will also look into the SWOT analysis of the firm to unearth strategic issues faced by the firm a nd what strategic options could be exercised to correct the situation. Company Background Smirnoff is a brand name managed by a British Company with the name of Diageo. It is however, important to note that Smirnoff as a brand has its historical roots in Russia when during 19th Century, Smirnoff as a vodka brand was started by Pytor Aresenievich Smrinoff. (Diageo Inc) Over the period of time, brand gained recognition and is now considered as the leading vodka brand in the world. What is also important to understand that Smirnoff was the only vodka available outside the communist countries after the Second World War? This therefore has given an edge to the brand to dominate the European and North American market and become the leading selling brand in the world. The company owning and operating this brand is also selling other brands which are also maintained as the strategic brands. These strategic brands therefore serve as the primary source of growth for the firm across all the ma rkets it operates. Some of the leading brands of Diageo include Johnnie Walker, Crown Royal, J&B etc. Smirnoff is also one of the strategic brands for the firm generating the required growth for the firm in the Spirit market.1 It is important to note that Smirnoff exists as a separate strategic business unit for the firm and it is sold through different channels. Delivery of the product through online market of the firm is also one of the ways firm manages sales for this brand. Target Market of the Company Diageo is considered as the premium drink company offering high worth brands to the individuals all over the world. As such the geographical distribution of the company’s target market is across the whole world with concentration in the European and North American market. It is critical to note that the drink market continuously evolve due to the market innovation and changing preferences of the customers. (ASIMOV, 2005). Though Diageo is a well diversified company with man y brands serving different niches in the drink market, however, Smirnoff caters to a different niche of the market. Though Vodka is famous for its uniqueness as a drink however, firm has been able to introduce new flavored drinks in order to cater to the needs of varying degree. The essential market for the drink comprises of those individual customers looking for ready to drink market with variety offered according to the Season of the year. This is because of

Why was Intel initially successful in DRAMs Assignment

Why was Intel initially successful in DRAMs - Assignment Example Dennard claims he went home and formulated the basic idea for DRAM within a few hours, as Mary Bellis explains, â€Å"Dennard and his team were working on early field-effect transistors and integrated circuits, and his attention to memory chips came from seeing another team's research with thin-film magnetic memory. Dennard claims he went home and within a few hours had gotten the basic ideas for the creation of DRAM.† Within two years after its release, Intel would become a world leader in DRAM technologies. Intel created the Memory Systems Operation to assemble the DRAM chips to standards required for sale to OEM’s (Original Equipment Manufacturers), who then put the chips into more sophisticated machines. This operation allowed Intel to distribute their technologies to a wider area. This strategy, in conjunction with offering replacement parts for mainframe computer memories, allowed them to gain more control over the market. Over ninety percent of Intel’s rev enue was brought in by their DRAM, which was the world’s largest selling semi-conductor. Always being the first into new markets, Intel used that strategy and the fact they were the first to release DRAM to heighten sales of the chips and create the success they did ( Lazonick 148-149). Intel’s business strategy was very aggressive and they knew how to play the market to maximize profits.

Need help to write reflection paragraph for my project about the strategy project on ( Cesim Business Management Simulations ) - Assignment Example We learned this during the course of the game. Sometimes, there just concepts that are too abstract for us to understand in a classroom setting and only appreciate it in a business setting. For example, we decided to make our costs and expense low in the last few rounds thinking that it would it increase our net profit by keeping the deductions down. Theoretically, our assumption should be right but it is just too simplistic to assume that net profit will increase if cost will be reduced because there are also other things to consider in making profit. In our case, we reduce our costs and expense to only 740,749 which is one of the lowest in the game. Theoretically, if our deductions were small, then our net profit should be high. We realize that it does not necessarily follow this way. Reducing costs, especially those that are critical in generating revenues is not always healthy for the business. We are also not efficient in using our resources to generate revenue. We may have one of the lowest costs in the game in terms of numbers but if we relate this to the revenue generated, we are in fact one of the costliest business if not the costliest. Now, this would be difficult to realize in a classroom discussion. We have a lot of fixed assets but it did not generate revenue and only incurred us depreciation of 437Â  722 which can be considered as the highest in the game even if it is not the highest in numbers term because it only generated a sales revenue of 1Â  273Â  665. These incorrect assumptions, led us to do poorly in the last few rounds of the game. We were doing great in the first few rounds but wrong assumptions pulled us in the read so to speak, in the last few rounds because we had wrong assumptions. Good thing this was just a game because if this was the real life, our team would have lost our shirt. The game served its purpose of letting us understand how various concepts and components in

Operations & Logistics Management - Essay Example Despite the fact that ISO standards are developed with the government support, certification on ISO 9000 is a completely voluntary matter. Pressure, constraining enterprise to carry out a certification, occur by users, but not legislative organs. Almost the most important fact, which is concerned this standard, is the fact that many companies, especially in Europe, require registration on ISO 9000 from their suppliers of goods and services. To cut the long story short we should say if there is no registration on ISO 9000 there is no concluded contract. In the USA, for example, NASA and Ministry of Defense now require certification on ISO 9000 from its suppliers. Let us consider the example of corporation DuPont, which is an example of enterprise, which corresponds to ISO. The activity of corporation is connected with world sales to the production of chemical industry. DuPont is one of the biggest chemical companies in the world. It was established in 1802 as manufacture for the production of powder. Nowadays DuPont produces a wide range of chemical products and conducts great innovational researches in this area. The company is an inventor of variety unique polymeric and other materials, such as neoprene, nylon, teflon, kevlar and other. The company was also developer and basic producer of the freon, utilized in the production of refrigerator devices. According to version of Fortune 500, the company occupies 66th place among the largest corporations of the USA. At present time DuPont is a multinational corporation that has 18 majo r businesses, operations in 70 countries and more than 60,000 employees. The gain of company in 2005 composed $26,6 billion. After the DuPont's certification in accordance with the requirements of the standards ISO 9000 it has began the stage of its implementation. Standards' implementation have not been so easy, since in comparison with the previous version (1994) serious changes underwent these standards, they now requires the reconsideration of approaches of management of quality and mastery of the new requirements, which are based on TQM philosophy and principles of the quality rewards models. Together with the unconditional progressiveness of the standards ISO 9000, especially new version, there is a potential danger of standards formal implementation. In the process of ISO standards implementation in DuPont there have appeared a range of complex problems, caused by the need of the systematic guarantee of realization of positions and requirements of these renovated standards, training of specialists and experts, and also by the lack of preparation of many certification organs for the work regarding c orrespondence of the systems of quality to new requirements.The main task, which have stood before the management of company was to avoid formal implementation into of ISO 9000 standards, since formal approach to this matter can bring only loss of time and expenses, and disappointment in standards themselves. Actually, under specific conditions ISO 9000 standards can not only prove to be

What is the essence of philosophy Essay Example | Topics and Well Written Essays - 750 words

What is the essence of philosophy - Essay Example n order to define what the essence of philosophy really is, I decided to examine the range of philosophers and philosophies that we have covered in class. In Chinese history there are tales of philosophers who placed an emphasis on finding a way of living a good life, which suggests that philosophy has to do with morality and self-control and this is very similar to some of the moral philosophy as taught by the ancient Greek philosopher Socrates. It is also similar to some of the teachings in the major world religions which see human life as a journey towards enlightenment or a preparation for an afterlife. This contrasts very strongly with some of the medieval European philosophers who emphasized the use of reason, and the power of thinking through issues using logical trains of thought. In the twentieth century there has been a considerable emphasis on language and on existential problems like the meaning of human life. In the twenty first century there is a growing realisation of the fragile nature of the planet earth and the need for human beings to find ways of living that are in harmony with nature, rather than just pursuing mat erialist aims, and disregarding or even destroying the environment around them. The most noticeable feature of philosophy appears to be its diversity. It changes from place to place and from one time period to the next. All of these different approaches can be called philosophy and one way of defining the essence of philosophy is to establish what it is that they all have in common. I think that asking questions is a fundamental part of philosophy, and then weighing up the answers that are found in such a way that new questions are asked and a continuous process of asking, answering, reflecting and asking again then follows. This is not exactly the same as the kind of questions that are asked by scientists, who are mostly interested in how the elements in the world behave and what rules exist in the universe. Philosophy explores

The role of emotion in racial prejudice Essay Example for Free

The role of emotion in racial prejudice Essay Racial prejudice was defined by Allport , one of the first researchers in psychology to investigate the issue, as an aversive or hostile attitude towards a person who belongs to a group, simply because he or she belongs to that group, and is therefore presumed to have the objectionable qualities ascribed to that group. It is an antipathy based on a faulty and inflexible generalization (Allport, 1954). Racial prejudice exists on 3 levels: behavioral, cognitive and affective. The actual discrimination or unequal treatment towards a particular group based on their race is the behavioral component of racial prejudice. The cognitive component is made up of stereotypes. Stereotypes are categories of cognitions concerning the members of a particular group. These cognitions are usually simple, often over generalized, and frequently inaccurate. Stereotypes are not simply abstractions about group categories. They can act as cognitive filters through which we select what information to use, what to ignore, and how to interpret it. Stereotypes do not exist in isolation. They are accompanied by emotions, which are usually expressed in terms that can be distributed along a continuum ranging from the intensely negative to the very positive. (Simpson and Yinger, 1972) The emotional level is a major element of racism, because it serves as the motivation for stereotyping. Stereotypes would not be so powerful without affective links. After the cognitive level has been challenged and undermined, one continues to maintain stereotypes at the emotional or affective level. As the intensity of emotion increases, so does the level of prejudice. This paper will explore the influence of emotions on ones unconscious and conscious inclinations towards stereotyping and racism. Fear, anxiety, disgust and anger are all emotions that exist at the root of racism. According to an evolutionary perspective, fear is one of the most motivational emotions humans have in their bodies to keep them alive. It protects humans from danger, by motivating them to fight back when they are being threatened. This fight manifests itself in many different ways, but in the context of racism it is in the form of discrimination towards an out-group. This explains racism as a means of fighting back when an individuals fear has been aroused due to perceived threat to an ones fundamental needs by the out-group. Fear exists in the reptilian brain, the very basic area of the brain and it can sometimes be aroused unconsciously. Fear can cause neurotransmitters to fill the brain, bringing an individual to such a heightened state of arousal that the cause of fear becomes internalized. (Le Doux, 2002) In the context of racism, if an individual or group is identified with that arousal, an association is made that is not easily removed. This evolutionary logic leads to many thoughts about factors in modern day society leading to the acquisition of new stereotypes and prejudices, as well as the endurance existing stereotypes and prejudices. For example, a recent study conducted by Schaller, Park and Mueller investigated the effect of ambient darkness and thoughts about danger on stereotypes about Blacks. The participants were placed in either a well lit or dark room, then they were presented photographs of black males and asked to rate how much they represented the cultural stereotype. The study also included a separate questionnaire to assess each participants thoughts of living in a dangerous world. The results showed that when the participants were in the well lit room, their level of perceived danger in the world did not have an effect on the intensity of their stereotypes of blacks. However, when the participants were in the dark room, stereotypes of blacks were more intense in association with their level of perceived danger in the world. To people everywhere darkness is a threat, it presents danger due to vulnerability and has evil connotations. This study clearly illustrates the relationship between racism and fear. (Schaller, Park Mueller, 2002). Inter-group anxiety has been proven to be another motivator for racial prejudice. High levels of intergroup anxiety may amplify normative behavioral patterns, cause cognitive and motivational information processing biases, intensify self-awareness, and augment emotional reactions (Stephan Stephan, 1985). Stephan and Stephan proposed that intergroup anxiety stems mainly from the anticipation of negative consequences for oneself during contact. Much of the intergroup anxiety may be caused by minimal previous contact with the outgroup, the existence of large status differentials, and a high ratio of outgroup to ingroup members. Stephan and Stephans own study of Hispanic Americans perceptions of Anglos showed that high voluntary contact was negatively associated, and that high believed dissimilarity and stereotyping were positively associated, with intergroup anxiety. It was predicted that increased contact (under appropriate conditions) would be associated with decreased intergroup anxiety and that, in the context of our field study of minority and majority religious groups, intergroup anxiety would be higher for minority group members. (Stephan Stephan, 1985) The Social-identity theory is widely used as an explanation for prejudice. According to Social-Identity theory, an individual attains self-concept and self-esteem through membership to a particular group. A high need for esteem and belonging are often associated with racism because of the psychological need it fulfill it to feel superior, (which in actuality is a state of inferiority). In order for individuals to feel as though their group is meaningful and has status, it is unconsciously necessary for them to place others below them. In applying emotion to this model of prejudice, it is evident that fear of rejection acts as a motivator for out-group discrimination in order to protect ones own ego. A newer model of prejudice; Intergroup Emotions Theory, combines this social identity perspective with the assumptions of appraisal theories of emotion. Intergroup Emotions Theory claims that emotions are caused by the collective aspect of the self. For example, when an outgroup is appraised as threatening an ingroup, negative intergroup emotions such as fear or anger may result, and become part of a general prejudice against the outgroup that may motivate discriminatory behavior. Thus, Intergroup Emotions Theory holds that emotions experienced by individuals with respect to their group memberships make a unique contribution to prejudice and intergroup relations. In association with the Intergroup Emotion Theory which recognizes the appraisals and attribution process in racial motives. Esses, Haddock and Zanna point out that there is more to prejudice than merely the attribution of stereotypes to groups. Their research suggests that the emotions elicited by a particular group are important in determining ones level of prejudice. When one is in a good mood, he or she is likely to evaluate members of out-groups more favorably than when he or she is in a bad mood. (Esses, Haddock Zanna, 1993) Another example of the role emotion plays in predicting racial prejudice is illustrated in a study by Esses and Dovidio. They found that when white students were shown a videotape of a black man experiencing discrimination in several situations and asked to focus on their feelings about each situation, they felt more positive toward blacks and were more willing to interact with blacks in the future than students who were told to pay attention to their thoughts in this regard. Aversive racism is yet another way in which emotion is seen as a factor in racism. Aversive racism is accompanied by feelings of anxiety, which are caused by intergroup expectancies and by the contribution of ignorance that often coexists with fear. Gaertner and Dovidio state that aversive racism is excluded from conscious awareness and amplifies positive behaviours toward a minority group. Negative feelings follow these overly positive behaviours. Gaertner and Dovidio indicate that there are several possible negative emotions involved such as discomfort, anxiety, uneasiness, disgust and even fear. These emotions occur because of the extreme cognitive exercise necessary to avoid expressing unacceptable racist comments. Once again it is being suggested that negative emotions mediate the relationship between stereotypes, which are unavoidable, and prejudice that includes affect. (Gaertner and Dovidio, 1986) The studies mentioned throughout this paper prove that emotions play a significant role in human tendencies towards racial prejudices. It is also evident that these tendencies can be in many ways unconscious. However, much of this research has also shown that if humans are made more aware of the role that their emotions play in these prejudice thoughts and actions, they can learn to monitor them consciously. Also other research has noted that by increasing intergroup contact racism between groups will decrease. Racial prejudice is a major social problem that must be alleviated and more research in this area will always be beneficial in helping society become more unified.

Multifunctional Porous Organics Synthesis

Multifunctional Porous Organics Synthesis TITLE OF WORK The synthesis and characterisation of functionalized porous organics Abstract Lophine based radicals have been studied for many years due to their photochromic nature, recent literature has seen attempts to connect two radicals to carbon based backbones. In this report we will discuss attaching six lophine molecules to a single backbone which is a phosphazene ring. Cyclophosphazene rings have a unique conformation allowing for supramolecular architectures to be formed by varying the substituents, these architectures range from 0-2D structures. The hexalophine molecule exhibits 1D channels due its unique conformation which leads to the formation of a porous material. Porous organics are of high interest in recent literature due to them being a cheaper, less toxic alternative to MOFs as well as having the ability to be modified and tailored easily due to the simple starting materials. In this report we shall state synthetic pathways from simple molecular building blocks to hexalophine (32%) and two derivatives, compound 4 (46%) and 5 (15%). These two derivatives have the potential to increase pore stability. This report will also include the oxidation of hexalophine to its radical species which were found to display photochromic properties and it is also believed that this material could contain light gated pores which are closed in the dimer form of the product but then open upon irradiation of UV of 365nm. 1. INTRODUCTION 1.0 Properties and potential uses of Lophine This report will feature chemistry based upon the triphenylimidazolyl based radicals (TPIRs) as well as the dimer form hexaarylbiimidazole (HABI). Lophine (2,4,5-triphenyl-1H-imidazole) is a heterocyclic imidazole derivative where three phenyl rings are attached to the imidazole ring (figure 1), these imidazole derivatives are an area of importance due to the many interesting properties it possesses. Lophine has been of interest to researchers for many years with its chemiluminescent properties being first discovered in 1877 by Radziszewski.1 The oxidation of the lophine molecule follows the reaction scheme below, where lophine is oxidised to the TPIR radical state via addion of base and treatment with Fe forming one of six dimers both in solution and the solid state (figure 2). These materials display photochromic, thermochromic and piezochromic properties. The mechanism of photochromism of the lophine dimer is the homolytic cleavage of the 2C-1N bond of the dimer by irradiation wit h light, forming two lophine radicals.2 The fast colour change associated with this dimer opening means there is a potential use in display screens or as the basis for molecular switches, where irradiation with light opens the dimer forming the radical in turn switching the external component On/Off. These possible applications have caused a focus on creating methods to manipulate and control the colour of these materials and as well as to increase the rate of switching.3 The colour of the radical form is dependent upon the substituents on the ring, the more conjugated the system the further toward the red side of the spectrum the colour.4 Lophine displays piezochromic properties in its solid state, upon applying pressure lophine crystals the colour change of yellow to blue/green has been observed, this occurs via the radical dissociation of the 1N-1N dimer bond.5 Other more unusual modes have been of dimerization such as the 2C-2C have now also been isolated, this mode features a u nusually long C-C bond.3 Figure 1 The structure of Lophine (2,4,5-triphenyl-1H-imidazole) Another interesting lophyl radical derivative is the 1,8-TPID-naphthalene radical which consists of 2 lophine radicals connected by a naphthalene ring. 1,8-TPID-naphthalene has been characterised in the solid state by Abe et al; who studied the photoreactivity of the compound. 1,8-TPID-naphthalene allowed the group to fix two radicals onto a backbone meaning that the radicals were in close proximity and could dimerise easily as opposed to two radicals not connected via a backbone which first need to find eachother in order for dimerization to occur (figure 3). They found that the dimer could be cleaved photochemically giving the diradical and then could be thermally converted back to the dimer.6 They also found that the formation of a peroxide bridge was much more common than previous literature had accounted for. This bridging occurred when the 1,8-TPID-naphthalene radical was placed under an O2 atmosphere.7 This peroxide bridge formation is very important as when oxygen quenches th e spin to form the closed shell peroxide it does so irreversibly meaning the material is no longer photochromic. It was then shown that this peroxide degradation pathway can be generalised for the chromic dimers of TPIR materials, with non-tethered TPIRs forming similar peroxide bridges.8 A recent development by the same research group has also shown how a thiophene substituted phenoxyl-imidazole radical complex (PIC) can generate two non-equivalent radical upon irradiation with UV light. The colour change can be fine-tuned from tens of seconds to nanoseconds, however a sensitivity to lower wavelengths of light meant that applications were limited. This problem was rectified by adding a phenyl group to the 5 position of the thiophene ring.9 Figure 2 The six potential dimerization modes of two lophyl radicals.3 Figure 3 Illustrates the reversible conversion of 1,8-TPID-naphthalene between its radical and dimer forms. 1.1 Hexa-substituted Phophazene Rings, Tectons and Crystal Engineering A key component of this project was the exploitation of the Phosphazene ring as soft tecton; a tecton is a molecular building block that interacts with sticky sites, formally known as supramolecular synthons, via spatial arrangements to induce the formation of supramolecular aggregates. The search for new tectons is a hot area of research due to the constantly growing field of crystal engineering where the aim is to produce functional single crystal materials using intermolecular interactions. The arrangement of molecules in solid state structures is largely dependent on striking a fine balance between intramolecular forces and packing interactions, knowledge of these forces is key to the field of crystal engineering.10 In general, hard tectons interact via more robust synthons than soft tectons and therefore usually crystallise with unambiguous geometries. Whereas soft tectons and less robust synthons allow for the formation of supramolecular isomers (figure 4).11 These tectons allo w for many functional materials to be formed in a one pot synthesis, they also have the ability to be carefully adjusted to alter and improve upon their functionality.12 Cyclophosphazenes are extremely soft tectons that interact with soft synthons to give a large variety of supramolecular architectures in the solid state. The conformation of the cyclophosphazenes is also very interesting as three substituents reside above the plane of the ring and three below (figure 5). It was found that small modifications to the substituents attached to the ring gave supramolecular architectures ranging from 0D to 2D structures (figure 6) such as include monomer, dimer, cyclic hexamer, zigzag chain, linear chain, double chain, graphite-type sheet, rectangular grid and hexagonal close-packed sheet. Such variety of structures came from the easy rotation about the exocyclic P-N bonds, which allowed variable directionalities for all of the N-H bonds. 11   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   3a)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   3b) Figure 4a) Shows benzene-1,4-dicarboxylic acid a classic example of a hard tecton. 4b) shows a silanetriol a classic soft tecton.

Figure 6 Schematic representations of aggregation patterns of (RNH)6P3N3 in the solid state.11 1.2 Magnetism and Magnetic Frustration The materials we aim to make during this project once appropriately oxidised should go on to form dimers which when irradiated with UV light form discrete radicals containing unpaired electrons thus giving each radical an associated magnetic moment. Neutral organic radicals tend to be paramagnetic and exhibit Curie- Weiss behaviour, where the spin vectors of the unpaired electrons are randomly aligned above the Curie temperature (Tc), which is the critical temperature below which the long ordered state is established, unless a magnetic field is applied. If spin vectors are parallel to each other below the Curie temperature then the material is ferromagnetic, if the spin vectors are aligned antiparallel to one another the material is antiferromagnetic.13 Due to the geometry of the phosphazene ring (three substituents pointing up above the plane of the ring and three below) there is the possibility of forming a 2D triangular lattice of spins if the substituents are organic radicals.   This could possibly lead to geometric magnetic frustration due to the fact that the two nearest neighbours to a spin are themselves nearest neighbours and therefore antiferromagnetic couplings cannot be satisfied (figure 7).14 This can lead to very interesting magnetic properties. Most solid state examples of this geometric frustration tend to be transition metal oxides, however, studies have been done on organic systems that also distribute geometric frustration.13 One example of this is m-MPYNNP+ which is a spin  ½ organic radical that upon dimerization forms a 2D triangular lattice which demonstrates the aforementioned geometric frustration.14 The issue of spin frustration has been around for a long time as Quantum spin liquids (QSL) were first theoretically proposed by Anderson many years ago which are now a hot topic of research due to the realisation of these QSLs in organic materials such as k-(ET)2-CH2(CN)3, which has a near perfect triangular lattice with angles very close to 120 °.15 A QSL is an exotic ground state where interacting spins continuously fluctuate with no formation of   low range magnetic order even at sufficiently low temperatures.16 Figure 7 Antiferromagnetic coupling cannot be fulfilled causing geometric magnetic frustration. 1.3 Porous Materials Porous materials are as important as ever due to their wide spread use in several fields such as catalysis and gas absorption,17 meaning they can play a critical role in the route to solving our growing energy shortage problems. Porous materials are instantly associated with materials such as zeolites, metal organic framework (MOF) and organic polymers. MOFs are characterised by their tuneable pores and inherent flexibility which more classical carbon or oxide based structures do not possess, this gives a wide range of applications for MOFs such as gas storage, separation, drug delivery or catalysis.18 Porous organics have been discovered in nature but are largely created synthetically and approaches often need to be coupled with knowledge of crystal engineering. These materials are often held together by directional forces which form extended frameworks of noncovalent interactions such as Ï€- Ï€ interactions, hydrogen bonding or coordinate bonding (figure 8).17 Like zeolites a nd MOFs porous organics have the ability to selectively absorb atoms and molecules in the gas phase.19 There are many positives to these porous organics, they are often cheaper to synthesise and less toxic as well as being far less dense than metal containing MOFs. Figure 8 One example of a Porous Organic by Sozzani et al. 1.4 P3N3 Hexalophine The chemistry of P3N3 Hexalophine incorporates much of the chemistry discussed above and has many interesting properties. The P3N3 Hexalophine molecule consists of six lophine substituents attached to the phosphazene ring via a P-O bond (figure 9). Previous work in the Robertson group found that the solid state structure of Hexalophine consisted of a pseudo hexagonal motif giving rise to 1D channels that run parallel to the stacking axis (figure 10). The molecule maintained its D3 symmetry in the solid state. The phenyl rings twist to maximise pi-stacking interaction and the 3 imidazole nitrogen atoms form hydrogen bonds to a central water molecule. There are 4 pi-pi interactions that stabilise this structure, the molecules are in a slipped conformation allowing the phenyl and imidazole to rings overlap. Other non-covalent interactions such as van der Waals interactions also help to stabilise the structure. The high symmetry of the structure which comes from the hexa substituted phos phazene ring (three above the plane of the ring and three below) gives an equal distribution of intermolecular forces giving a high probability of forming a stable porous structure. IGA measurements with CO2 loading at 195K shows a Type I isotherm with absorption reaching 8cm3g-1 at a pressure of 700mmHg confirming the materials microporosity. However only a small fraction of the void space contained CO2. Figure 9 The structure of Hexalophine. Figure 10 The crystal structure of Hexalophine, illustrating the 1D channels. 1.5 Aim of Project The aim of this project is to combine our knowledge of the chemistry of both lophine radical systems and cyclophosphazene rings to find elegant synthetic routes which will improve upon the porous properties of hexalophine. This will be done by varying the ring substituents to increase stability of the pores and to improve its gas absorption properties. Three lophine derivatives have been identified as plausible candidates for thid are where two of the phenyl groups on the lophine will be replaced by two thiophene rings and two pyridine rings respectively, with the position of the nitrogen in the pyridine ring being varied depending upon the synthetic pathway (figure 11). We wish to synthesise and fully characterise these derivatives including growing single crystals for structural studies via X-ray crystallography. Also a stoichiometric controlled oxidation of the hexalophine material to its neutral radical/dimer pair is required in order to further investigate the properties of hexa lophine such as the possibility of creating a photochromic material that has light gated pores that open on irradiation with UV light.

Results and discussion 2.0 Hexa-benzaldehyde Synthesis The first step in this synthetic project involved attaching six benzaldehyde units to the phosphazene ring via a P-O oxygen bond. This was achieved by reacting the phosphonitrillic chloride trimer along with 6 equivalents of 4-hydroxybenzaldehyde, potassium carbonate in dry THF (figure 12). The reaction was monitored with 31P NMR which showed completion when only a singlet was present in the spectra indicating full substitution. This produced the compound 1 which was the precursor for many of the subsequent reactions. The reaction gave the desired product in a fairly low yield (45%). Whilst the yield was slightly low the FT-IR showed all of the characteristic absorptions such as C=O (1697cm-1) and CAr-CAr (1585cm-1). 31P NMR was conducted and showed a sharp singlet at 7.08ppm which indicated full substitution on the phosphazene ring as all of the environments are equivalent. 1H NMR was also conducted and show a singlet at 9.87ppm with an integration of 6Hs which was as expected for t he 6 aldehyde protons, two doublets were found in the aromatic region and integrated to 12Hs each which was correct for the number of protons expected. The CHN analysis was almost perfect with less than 0.2% difference from the calculated values, this indicated that the product was of high purity. Mass spectometry also indicated that the desired product had been synthesized as a [M+Na]+ peak was detected at 884. Figure 12 The reaction scheme for the synthesis of 1. 2.1 Synthesis of Hexalophine and Hexalophine derivatives 2.1.0 Using Diketones The synthesis of hexalophine and hexalophine derivatives is important due to their porous properties which can be of great importance in fields such as gas storage and catalysis. The method for attaching six lophine units to the ring was a ring condensation of 1 on the six benzaldehyde units attached to the phosphazene ring using a synthesis based upon Radziszewskis synthesis.1 The product 2 was achieved by reacting 1 along with six equivalents of benzil, ammonium acetate in excess in glacial acetic acid (figure 13). The yield for 2 was quite poor (32%), the FT-IR showed all of the characteristic peaks such as CAr-H (3055cm-1), C=N (1604cm-1) and CAr=CAr (1538cm-1) indicating the desired product had been formed. This was further confirmed by both the 31P and 1H NMR, the 31P NMR showed a singlet at 8.36ppm which indicates full substitution on the phosphazene ring. The 1H NMR showed a singlet at 12.65ppm which had an integration equal to 6Hs which is representative of the 6 imidazole N -Hs, it also showed multiplets in the aromatic region with an integration of 84Hs which is exactly the number of aromatic hydrogens in the desired product. CHN analysis of the product correlated well with the desired structure, especially when three molecules of water were factored into the calculation. It is unsurprising that this compound also contained water due to its porous nature.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   NH4OAc   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Acetic acid (6eq.) Figure 13 The reaction scheme for the synthesis of 2. Another reaction designed based upon the ring condensation reaction was the synthesis of 4. This synthesis builds upon the diketone functionality as above, however, in this reaction the R groups of the diketone thenil were thiophene rings as opposed to the phenyl rings of benzil. Thenil like benzil was reacted with 1 and ammonium acetate in glacial acetic acid (figure 14). The yield for this compound, whilst better than 2, was still fairly low (46%). FT-IR showed the characteristic peaks such as CAr-H (3071cm-1), CAr=CAr (1643cm-1) and C=N (1607cm-1) indicating the target molecule had been synthesised. The 31P NMR showed a singlet at 8.26ppm again indicating full substitution. The 1H NMR showed a singlet 12.91ppm with an integration of 6Hs representative of the 6 imidazole N-H hydrogens, it also showed multiplets in the aromatic region with an integration of 60 which was again exactly what was required for the number of aromatic hydrogens, indicating the correct product had been synt hesised. The CHN analysis was close to the theorectical values required especially when four water molecules were factored in, again this is unsurprising as this material like 2 is also expected to be porous.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   NH4OAc   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Acetic acid (6eq.) Figure 14 The reaction scheme for the synthesis of 4. Like thenil and benzil, pyridil is also a diketone where the two R groups are heterocycles, in this case the two heterocycles are pyridine rings. Pyridil was used again with the classical Radziszewski based synthesis to synthesise the compound 5 (Figure 15). The yield for this compound was very low (15%) due to a lot of mass lost upon recrystallization and decomposition upon heating. The FT-IR showed the correct absorptions for the key functional groups such as C=N (1600cm-1) and P=N (1158cm-1) indicating that the target compound had been synthesised. However large OH absorption band (3349cm-1) was also present showing that the product contained a considerable amount of water or ethanol. CHN analysis of the compound showed a vast difference in carbon and nitrogen values when compared to the theoretical values indicating some impurities in the sample. The fact that the product contained considerable amounts solvent would also skew the result of the CHN analysis somewhat.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   NH4OAc   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Acetic acid (6eq.) Figure 15 The reaction scheme for the synthesis of 5. 2.1.1 Using Aldehydes for an alternative preparation The idea of using aldehydes such as pyridine carboxyaldehyde and benzaldehyde as opposed to the diketones used above was born when questioning on how we could stabilise the pores in the materials we wished to synthesise as larger groups could be added to these aldehyde starting materials. An alternative synthesis of 2 using twelve equivalents of benzaldehyde is illustrated in figure 16. The reaction was left to reflux for 7 days however the 31P NMR showed a multiplet indicating that full substitution had not occurred or a mix of products was present. Unfortunately, this was a reoccurring theme as the failed synthesis of 3 using twelve equivalents of pyridine carboxyaldehyde (figure 17) also showed a multiplet in the 31P NMR. Benzaldehyde (12 eq.) Figure 16 The reaction scheme for and alternative preparation of 2. Carboxyaldehyde (12 eq.) Figure 17 The reaction scheme for compound 3. 2.2 Oxidation of Hexalophine and its derivatives The oxidation of hexalophine is of great interest due to the potential properties it may possess, such as it possessing photochromic properties which may lead to light gated pores. For this oxidation an excess of potassium hydroxide was used to create the anion before 50 equivalents of the classical oxidising agent potassium ferrocyanide (III) were used to perform a one electron oxidation to the radical species 6, a yellow to orange colour change is associated with the formation of the radical species. This radical species quickly dimerises and an orange to yellow colour change is associated with this. Upon irradiation with UV light (365nm) the dimer opens to form two radicals, the colour change associated with this was yellow to purple displaying the photochromic behaviour of this compound (figure 18). The radical species is stable for a number of hours in the solid state unless gentle heating is applied which induces dimerization again and the colour change of purple to yellow is a ssociated with this. FT-IR showed characteristic absorbances of CAr-H (2955cm-1), C-N (1301cm-1) and P=N (1198cm-1) which are present in the desired product. The thiophene hexalophine derivative 4 was also oxidised using the same classical oxidation conditions as above to form its radical species 7. Upon separation the system formed 3 layers, an organic layer, an aqueous layer and a solid substance formed which was soluble in neither. Both the organic layer and solid substance were irradiated with UV light to test for photochromic properties however neither displayed a colour change and thus further testing of this material via UV/Vis spectroscopy is required to determine its nature. Figure 18 A RBF containing the hexalophine dimer and radical, the purple is the radical species, the yellow is the dimer species. 3. Conclusions and further work The aim of this project was to synthesise and characterise functionalised porous organics based upon hexalophine as well as to perform oxidations to the radical species and study their properties such as photochromism. For the most part the aim of the project has been met as two derivatives of hexalophine (4 and 5) and hexalophine (2) itself have been synthesised from simple molecular building blocks and characterised using a range of spectroscopic techniques such as NMR, FT-IR and CHN analysis. The next step in the characterisation of these materials would be to gain crystal structures via x-ray crystallography to show the packing arrangement of these molecules and to prove the existence of pores with in the molecule created from the unique conformation of the phosphazene ring. Additionally, once crystal structures have been gained gas absorption test should be taken to test both the gas uptake properties and selectivity of certain gases. Yields for these experiments were quite low and the aldehyde reactions did not demonstrate full substitution onto the ring, one possible solution would be to try the reaction in a Parr pressure reactor. The oxidation of hexalophine was carried out with great success as the experiment demonstrated the proposed photochromic nature of the material, also the stability of this material with respect to air was very surprising. If possible crystal structures for this material should be obtained in order to investigate further the possibility of light gated pores which when the molecule is in the dimer form are closed but once in the radical form are open. 4.

Over the years, our accounting system has evolved from the tedious task of manual accounting to the ease of computerized accounting systems and programs. Computerized accounting has brought about a more efficient way of setting up and maintaining a company’s financial records. In previous years accountants would spend copious amounts of time manually recording business transactions through journalizing, posting to ledgers and mathematically checking each journal and ledger for errors. This process was necessary in order to compile data needed to produce financial reports and statements. The number of manual entries were so numerous that the margin of error was significantly increased. Simple mistakes, such as transposing a number or incorrectly recording a transaction in the wrong column could create a ripple effect of errors throughout each journal, ledger, or report issued for that period. The process of tracking one simple sales transaction was incredible compared to today’s accounting software. Manually, the transaction might begin with an invoice or sales receipt which beg...

Two policeman, Sir Thomas Legge and Inspector Maine, discuss the perplexing Indian Island case. They have reconstructed much of what happened on Indian Island from diaries kept by various guests. It is clear to them that the murderer was not Blore, Lombard, or Vera. When they arrived, the police found the chair Vera kicked away to hang herself mysteriously set upright against the wall. We learn that Isaac Morris, who hired Lombard and Blore and bought the island in the name of U. N. Owen, died of an apparent sleeping-pill overdose the night the guests arrived on the island. The police suspect that Morris was murdered. The police know that the people of Sticklehaven were instructed to ignore any distress signals from the island; they were told that everything taking place on the island was part of a game being played by the wealthy owners of the island and their guests. The rest of the epilogue takes the form of a manuscript in a bottle, found by a fisherman and given to the police. It is written by Judge Wargrave, who writes that the manuscript offers the solution to an unsolved crime. He says he was a sadistic child with both a lust for killing and a strong sense of justice. Reading mysteries always satisfied him. He went into law, an appropriate career for him because it allowed him to indulge his zeal for death within the confines of the law. Watching guilty persons squirm become a new pleasure for him. After many years as a judge, he developed the desire to play executioner. He wanted to kill in an extraordinary, theatrical way, while adhering to his own sense of justice. One day, a doctor mentioned to Wargrave the number of murders that must go unpunished, citing a recently deceased woman he felt sure was killed by the married couple who worked as her servants. Because the couple withheld a needed drug in order to kill her, the murder could ne ver be proven. This story inspired Wargrave to plan multiple murders of people who had killed but could not be prosecuted under the law. He thought of the â€Å"Ten Little Indian† rhyme that he loved as a child for its series of inevitable deaths. Wargrave took his time gathering a list of victims, bringing up the topic of unpunished murders in casual conversations and hoping someone would mention a case of which they knew.

Alcohol Misuse Among Minors In The UK :: essays research papers

The law in this country states that it is illegal for anyone under 18 years to consume alcohol or to work in licensed premises; to buy alcohol or to have it bought for them anywhere. Those over 16 may drink a small amount with a meal in a specially allocated area, but beyond that they face arrest and prosecution.In spite of this the law is frequently broken. Following the example of adults, for whom alcohol is the most used drug, several surveys show that children try alcohol. 68% of boys and 54% of girls (in the UK) appear to have tried it by the age of thirteen. The majority may not drink to excess but many have already experimented with the effects of intoxication. The young do not seem to know the dangers and public houses frequently hold discos which attract them in. Stewards find it difficult to assess who is below the age limit. The increase in consumption expected when the price of alcohol falls is bound to include youngsters. the serious implications of this must be faced, not least because drug abuse is closely linked to alcohol abuse.Clearly the law has a role to play. The police must be encouraged to enforce age limits, and, if necessary, licensing hours should be restricted. Unfortunately, this may inconvenience legitimate drinkers and deprive landlords of potential legal business. Having extra police and stewards may be useless since 16 year olds are not easy to pick out anymore. One solution offered by the Portman Group is the identification card system whereby only 18 year old will carry age identification cards. This should help, but even one of the director involved admits it is only a contribution.The alternative lies in education. Adults can help by example and by de-glamorising alcohol. Children can be taught about the risks to health and to performance, about the chances of being involved in violence or serious accidents and the dependency which lands many in hospital wards.

Cyberbullying as a Social Issue Essay

           There are varius social issues that need to be highlighted today, but cyberbullying has in one way or the other impacted on everybody. Bullying is categorized as hostile behavior where a prevailing group abuses its authority by threatening a less central group (Maher, 2008). Bullying is a by-product of the capitalist society that advocates for personal advancement over any other goals. From a tender age, children are encouraged to be the best they can be. Instincts push people to achieve these results at any cost. The overriding instinct in most instances is personal survival and the need to dominate others. If an person does not have the right values, they devise ways to intimidate others out of the competition. In the past incidents of bullying were limited to the relatively few cases of face-to-face bullying. All this has changed in the information age. Proliferation of communication devices combined with the internet provides fertile ground for bullying. One re ason that could explain the rise in Cyberbullying is the anonymity that the internet affords. People know that they do not have to account for their actions online and therefore tend to be more belligerent than usual. In the past the threat of physical confrontation in bullying was always present, however, the internet has largely diminished that threat. Forms of cyber bullying          Previously, I thought that only on field bullying existing. However as we went deeper in the course I realized that there exists different types of bullying. I also came to learn that cyberbullying takes more than one form. Cyberbullying refers to a range of activities done online that are harmful to the well-being of the victim (NoBullying.com). These may take the form of flaming where an argument between two people quickly spreads to include more people each taking one side of the argument and hurling insults to people on the other side. Another form is harassment, where a bully humiliates the victim by sending hurtful images, text messages, or emails about the victim. This type of bullying has grown with the recent trend of making memes. Memes are images containing a message meant to ridicule the victim. Denigration is another form of Cyberbullying; the bully attacks and tarnishes the victims through spreading false information about them.             Impersonation is another form of Cyberbullying. The bully assumes the identity of another person with malicious intent. Closely related to this is outing where someone gains personal information about the victim using dishonest means such as impersonation. The bully then publicizes that information with the aim of humiliating the victim. We also have stalking which involves following the victim online in an unjustified way. As illustrated, Cyberbullying involves a myriad of activities taking place in the online space. These activities involve both passive and active participation by victims and bullies (InDirect) Causes of online bullying               Online bullying may happen for several reasons. First, bullying by popular kids happens because they want to maintain their popularity (Donegan, 2012). Such people use bullying to validate their popularity. Often, this requires the support of backers and henchmen who remain on the sidelines cheering actively and passively as the bully brings down the victim. This kind of bullying is likely to target famous people since attacking them provides the bully with potential for attracting more attention. In addition to popularity, hurting others makes such people feel powerful. The more people they bully the more powerful they become. Taking on famous figures boosts the power of such bullies to even greater heights (NoBullying.com).                The other group of online bullies is people who are less socially successful. This group forms the bulk of cyber bullies. They find solace in bullying as it helps them cope with their low self-esteem. Their objective is to fit in with their peers and bullying provides a chance to help them achieve this goal (InDirect). Cyberbullying requires even less courage than traditional forms of bullying. The internet with its anonymity helps people show their true colours. Cyber bullies might not be bullies in real life but since the internet provides them with anonymity, they take advantage of that to bully others (Donegan 2012).               Effects of CyberbullyingStudies have shown that bullying causes emotional damage to its victims though most of these victims find it difficult to admit it. In a study involving over 3000 students, researchers learnt that out of all bullying victims, 38% felt vengeful, 37% were angry, while 24% felt helpless. Another study conducted by the Cyberbullying Research Centre using a sample size of 468 students drew almost similar conclusions. They found that out of all the female victims 39% felt frustrated, 36% felt angry and 25% felt sad about it, the males figures were 27%, 36% and 17% for each of those respective categories. Females seem to show high susceptibility to bullying than males. However, this is hardly surprising since males tend to admit emotional weakness less readily than their female counterparts do (Hinduja & Patchin, 2009).             Sociologist Robert Agnew developed the Great Strain Theory, which hypothesizes that victims of bullying can develop problematic emotions, which cause deviant behaviour. The victim goes through a vicious cycle and this can result to the victim developing antisocial behaviour as they try to process their emotions and find an outlet for their anger and frustration (Hinduja and Patchin, 2009).               Bullying also takes a toll on the bully. According to the Office of Juvenile Justice and Delinquency Prevention report, over 60% of males with bullying tendencies between grade six and nine were later convicted of at least one crime in their adult life. This is in comparison to 23% of people who did not bully. Forty per cent of these former bullies got at least three conviction by the time they were age 24 years; this is in comparison to 10% of those who were not bullies (Donegan, 2012). When bullies use bullying as a coping mechanism it leads to development of a vicious cycle for both the victim and the bully (Oleus, 2001). Evidently, bullying has a heavy toll on the society, the effects of this habit are long lasting, and some individuals feel the repercussions throughout their life. Solutions             Solutions to Cyberbullying will come from solving the general problem of bullying since Cyberbullying is only a subset of the wider problem of bullying. Wiseman reports a study conducted in Nevada that identified six essential elements in dealing with bullying in schools; availability of a reporting procedure, integration in the curriculum, student-centred approach with students taking the initiative of stopping the practice, prevention rather than punishment, effective punishment to deter the practice, and keeping up with technology. A solution to bullying must incorporate all stakeholders involved in growth of a child starting with parents and teachers (Wiseman, 2011). Conclusion          Capitalism subconsciously fosters bullying by placing pressure on individuals to succeed. However, this is not a reason to tolerate this vice. Competition is only good if it is fair and productive. The rise in bullying should be viewed in the context of moral decay of the society. Advances in information technology and emergence of social media have led to the evolution of bullying with new forms of bullying occurring in this new space. The toll of bullying in society is huge and steps must be taken to address this menace through legal and social means.

Leading Marines Essay

As we know leading Marines is the most important part of the Marine Corp. There are eleven leadership principles, and fourteen leadership traits a great leader demonstrates. These traits &principles help you suppress the leaders that came before us. Everyone has their own style of leadership though. Great leaders must embrace the ethos; Respect and follow the foundations. Accept the challenges he or she will face ahead. A Marine lives by his or her ethos. It’s what makes us a different breed. We are bred to better than the rest. Ethos consists of being a rifleman, carrying on traditions, and does what it takes to get the mission accomplished. Henry Hank Elrod demonstrated prime ethos during the Chosin Reservoir. Elrod lead a platoon in heroic defense for fifteen days. His platoon also demonstrated good ethos for showing the willingness to obey, and determined to follow orders. Also they upheld pride and confidence at all times during the rough times. Leading by these ethos isn’t about the rank you wear, but what’s in your heart. Leaders have to set the example by respecting and following the foundations of the Corp. These foundations are unique. It is putting forth the everyday principles we learned in boot camp, living by a higher standard than everybody else. A good leader is always learning, and uses ethical decision making. Leaders must have respect of their followers, or their words are meaningless. Followship is just as important as the leadership, to have followers as leader a Corporal once said it best,† Strive to create discipline in yourself and your Marines. † Marine leaders go through some of the toughest challenges, whether in combat or garrison. These challenges include: Physical, Mental, and Moral. The biggest type of challenge a leader can face is friction between Marines. Keeping everybody happy is virtually impossible, but as a leader you must try. A physical challenge is keeping combat ready and or not letting body get out of standards. â€Å"Guts and pride cannot replace physical fitness. † Mental challenges as a leader is a huge part in developing to even better leader. Making the right mental decisions can keep your Marines out harm’s way. The moral challenge is the one where a leader has to look within to see the answer. Keeping up with moral is defined by little moments that reflect a leader’s standards. In all being a Marine Corps’ leader is the most sought after, and respected job. A great leader keeps up with his or her ethos, foundations, and is up to the challenges. In the end it’s all about the relationship and the bond which cannot be broken. Leaders teach from history. Just remember the traits and principles that were set fort; â€Å"Marines are not born knowing them, but must learn what they are, and what they represent. †

The Boxer Rebellion and the Christian Response

The Boxer Rebellion was a vicious uprising against non-Chinese in China during the final years of the 19th century, from November 1899 to September 7, 1901. The areas of conflict included the commercial market, political domain, religious concerns and technological advancements. This extremely unique and glaring because in a very short span of time, thousands of Christians, both Chinese and foreign were killed as a result of the revolt and its suppression. Then ironically, the revolt itself was crushed by the very thing it stood against – foreign influence. About 20,000 troops came from outside to thwart this movement forever.â€Å"Thus as 1900 dawned, China was swept by a movement known as ‘Yao rebels’ who believed that they had been made invulnerable by sorcery and incantation. Screaming mobs, determined to kill every Westerner, were egged on by the Yao society whose title, â€Å"The Fist of Righteous Amity† was translated by Americans and English into B oxers† (Guy, 2006). It is not possible to highlight where this anti-western sentiment in China was actually born, but one may refer back to the opium war between Britain and China (1839-1842) for some indication. In 1839, the First Opium War broke out, and China cut a sorry figure in front of Britain.Eyeing the weakness of the Chinese, not only the British, but the Russians and the French as well started to exert their respective pressures upon the country. Due to their lack of power and ability to impose their will, China was forced into a number of treaties that subjugated its interest against others. These include: the Treaty of Nanking (1842), the Treaty of Aigun (1858), the Treaty of Tientsin (1858), the Convention of Peking (1860), the Treaty of Shimonoseki (1895), and the Second Convention of Peking (1898). Obviously, the public voice was against these treaties at large.Their ego was hurt badly, and their pride seemed to falter in front of the might of the foreigners. A s is common in such times, rumors also began to spread away. The foreigners were considered to be responsible for much crime and lawlessness that was prevalent. It was believed that the Church had started exercising more power than the state. It was also felt the Church had started to impose certain Christian practices, and had excluded certain tradition Chinese practices from the society. Thus in the late 19th century, feelings of unrest against the Chinese and the foreigners started to develop at a very rapid pace.Another major event was a row over a temple. The Catholics claimed that it was originally a church that had later been abandoned. The local court ultimately gave the verdict in favor of the Church. The locals could not tolerate this, as it was their place of worship and also a place to practice martial arts. To add to that, the colonization during the following decades did no good to boost up the morale of China. What was more, Asian powerhouses Russia and Japan also joi ned the rat-race for territorial supremacy. China came out as a good target for all those hungry to cut a slide of the earth’s map for their good.After the 1895 war of China with Japan, many European powers stepped forward to occupy Chinese territory. All of this mustered up into an intolerable feeling of hatred within the Chinese against their oppressors. â€Å"The conservatives then gave clandestine backing to the antiforeign and anti-Christian movement of secret societies known as Yihetuan (Society of Righteousness and Harmony). The movement has been better known in the West as the Boxers (from an earlier name–Yihequan, Righteousness and Harmony Boxers). In 1900 Boxer bands spread over the north China countryside, burning missionary facilities and killing Chinese Christians.Finally, in June 1900, the Boxers besieged the foreign concessions in Beijing and Tianjin, an action that provoked an allied relief expedition by the offended nations. The Qing declared war agai nst the invaders, who easily crushed their opposition and occupied north China. Under the Protocol of 1901, the court was made to consent to the execution of ten high officials and the punishment of hundreds of others, expansion of the Legation Quarter, payment of war reparations, stationing of foreign troops in China, and razing of some Chinese fortifications† (Onwar, 2000).While external forces were still contemplating a productive way out of the situation, the Chinese rulers came out with a message to the provinces. Given the circumstances and the options the rulers had, the message was by no means peaceful. It stated that the world was after Chinese resources and land, and that the time had come when the last resort should be adopted. Peace, therefore, was not an option to be considered. Meanwhile, in the northern Shandong province, a distressing drought was pushing people to the edge of starvation.There were not many who were thinking about peace anyways. All this energy had to be vented out somewhere, and hence came the time of catharsis, but in a violent way. Anti-foreign feelings caused the quick outburst of a Chinese secret society that was previously more docile. It was known as the I Ho Ch’uan, meaning the Righteous Harmonious Fists; hence the name ‘Boxers’. Understandably, with their name and mission, the Boxers asked for the expulsion of the external parties, more casually referred to as the ‘foreign devils’, along with their Chinese Christian converts.This was the time when conventional Chinese arts and skills thrived, especially martial arts and the use of traditional Chinese weapons. â€Å"At first, the Boxers wanted to destroy the Ch'ing dynasty (which had ruled China for over 250 years) and wanted to rid China of all foreign influence (which they considered a threat to Chinese culture). When the Empress Dowager backed the Boxers, the Boxers turned solely to ridding China of foreigners. By late 1899, ban ds of Boxers were massacring Christian missionaries and Chinese Christians† (Rosenburg, 2006).The resentment towards foreigners, Christians and Chinese converts started to rise immensely, with a greater tinge of violence. The circumstances forced the external lobbies to join hands, and they lodged strong protests with the government of China. However, the then Empress, Tzu Hsi’s response surprised many, when she declared that the Boxers were actually a part of the Chinese society, and hence should not be condemned as such. The reaction was also unexpected because it actually went against the local Chinese army, which was striving against the rebellion, and directed in favor of the Boxers.This made it inevitable for the external forces to make a show of military might close to China’s borders. â€Å"The empress dowager publicly opposed the Boxers, but her ministers quietly convinced them to join forces in order to drive foreigners from China. In the early months of 1900, thousands of Boxers roamed the countryside, attacking Christians. When an international force of 2,100 soldiers attempted to land in China, the empress dowager ordered her imperial army to stop the foreign troops.Throughout the summer of 1900 the Boxers burned churches and foreign residences and killed Chinese Christians on sight† (Dowling, 2001). Gradually, the Boxers started to gain autonomy over their beliefs and actions. The government was not ready to curb them, and their views were supported by many in the masses. The only effort that were going were in the direction of strengthening forces against the external attack. Finally, when the pressure was too much, the foreign elements inside started vocally seeking help from outside. It was then that the eight-country attack came into operation upon China.There were multiple operations, many of them fierce; gradually the Chinese rebellion started to weaken. Over the next several months, the forces from outside starte d to grow within China. They overtook Beijing (then Peking) and expanded into the country. Ultimately, the Boxers just a local might were no match for the military power of the industrial nations. Ultimately, in early 1901, the Chinese government gave in, and agreed to abolish the Boxer movement completely. Needless to mention, it was not merely an attack on the territory of China, but also on its ego.Succumbing to the demand of the external powers was worse than actually loosing a battle. Subsequently, due to its recent weakening in the region, China could do nothing in the war of Russia and Japan a couple of years later, and stood watching while Japan proclaimed supremacy in the East. In the entire episode, the United States played a very significant role. This is because it had a tactical advantage, having a major portion of its navy already established around the Philippines during the Spanish American War (1898) and the subsequent Philippine insurgent activity.This was actually a reinforcer for those policy makers in the US who were of the opinion that the US should maintain control in the Far East. It was a very unique time in the history of China, repeatedly, it had to face occasions when foreign invaders came in and took control of her land and might. The emperors were just too weak to make any resistance to this offer. An additional reason was that the foreign armies were far better equipped with warfare technologies and tactics than China was at that point in time. It was a time when the Empress began to reconsider her option regarding removal of these elements from her soil.

Management Styles in the Workplace

Title: Management Styles in the Workplace Purpose Statement: My purpose today is to inform you on four different management styles in the workplace. Thesis Statement: It is important for managers to understand their management style when certain situations arise in the work place, by knowing your management style you will become a better leader. Introduction: Have you ever been told, â€Å"Do it this way or don’t do it at all? † if so do you know what type of leadership or management style this.

Main Point 1: Democratic Management Style A. What is it? a. According to Building a Management Style, Democratic management builds commitment among employees in order to generate new ideas. It is one that seeks input from all employees and allows t he staff to use their own work methods, to get the task done in a timely matter. The Democratic Management Style is similar to the participatory leadership style because it produces moderate task efficiency but high satisfaction, according to the textbook.These two types of management style result in a transformational leadership approach according to the publication by Larry Thompson. This approach results in staff empowerment by making the staff or team feel that they are part of the decision making process, which will motivate your team and generate new ideas. B. What are the Advantages and Disadvantages a. Advantages: i. It is people centered ii. Encourages others to share ideas iii. Tolerating alternative views (understanding at there is more than one way of accomplishing the goal) b. Disadvantages: i.The manager could be taken advantage of due to employees not working to their full potential. ii. Moderate task efficiency iii. Slow down decision making process Main Point 2: Aut ocratic Management Style A. What is it? a. According to Building a Management Style autocratic managers do a complete 180 has far as treating his/Her staff. The book states this type of manager is single-minded about getting long-term results, and help from others. b. Autocratic management style is very similar to high directive leadership style studied in the textbook, such as; productivity is high, with little concern for people and their satisfaction level.The autocratic management style only offers one-way communication, and that is through the leader. This type of management style falls into the transactional theory according to the publication by Larry Thompson. B. What are the Advantages and the Disadvantages? a. Advantages: i. Although this type of management style seems pretty forceful there are many advantages. According to Managementstyle. org a few of the advantages are: 1. Instructions are forceful, 2. can make fast decisions, 3. less unexpected side track situations du e to lack of communication. b.Disadvantages: i. With such a Hitler style management approach there will disadvantages to using the autocratic management style, according to Managementstyle. org, such as: 1. The staff may feel useless as they are not consulted 2. Input from the staff is not allowed 3. Staff waiting on instructions (will cause delays) Main Point 3: Paternalistic Management Style A. What is it? a. According to learningmanagement2. com the paternalistic management style is combination of both democratic and autocratic management styles.Paternalistic managers will ask for the staff views and opinions, which allows them to feel involved, but in the end the manager will make the finial decision. b. According to Dr. Daniel Theyagu, who is a corporate trainer and seminar leader, suggest that by using the paternalistic management style approach, the leader will learn to move away from delegation to empowerment. i. Dr. Daniel Theyagu suggests leaders should stay involved with the development of their staff, so that the manager can be aware of his/her staff’s needs. ii.It is important for constant communication, to clear up any uncertainty among the staff and make sure everyone is on the same level for common values and goal of the project or task. iii. Dr. Daniel Theyagu also believes that when people feel involved they are more likely to ‘â€Å"buy in’ the visions and values of the leader. † Main Point 4: Laissez Faire Management Style: A. What is it? a. Laissez Faire Management style is also known as negligent leadership style in the textbook. According to the business dictionary website, laissez-faire management styles is a non-authoritarian approach to management.This type of manager feels that or â€Å"believes that people will excel when they are left alone to respond to their responsibilities and obligations in their own ways. B. What are the advantages and disadvantages? a. Advantages: According to about. com this type of management can be very effect if: i. When leaders are still there for consultation and feedback ii. Members are able to work alone and still be motivated iii. If Members are highly skilled, they do not need to wait on management to tell them how to complete the task. b.Disadvantages: In most cases the disadvantages out way the advantages because i. The lack of guidance may leave the staff feeling neglected. ii. According to the textbook, leader take no part in the decision-making process and offers little advice or direction. Conclusion: We are all managers of your own lives, but one day we will be leaders of others. Democratic management style allows others to take part in the decision-making process. Autocratic management style leaders make decisions without regards to others. Paternalistic allows for others input, but the decision is still up to the leader.Laissez-faire management style is a more hands off approach, and this type of leader style is not recommended for most si tuations. Knowing what the different types of management styles are, and what they mean, this can be an informative advantage to maybe using certain management styles in certain citations.

The main step for business growth IKEA took is to hire non Chinese managers and Chinese co-workers. The cross culture issues in international business Influence of cultural differences between china and Europe on IKEA IKEA is an international company owned by non-governmental organization. IKEA is the abbreviation of Ingvar Kamprad Elmtaryd Agunnaryd. each term in its abbreviation has its own history. Ingvar Kamprad is the Swedish 17 year's old man who founded this company in 1943. this man was grown up in Elmtaryd and his home parish is in Agunnaryd. it is the world's largest retailer that designs and sell knock-down or flat pack furniture, home appliances and accessories. IKEA also launched a family mobile (Aug 8, 2008), a virtual mobile network running on T-mobiles. IKEA is known as one of the best company which does a lot for the third world. It built an image for the low price furniture but for the Chinese customers the case was opposit e when IKEA opened the first store in Shanghai, China (1998). Most of the Chinese likes to visit IKEA store but they mostly of them just wandered there and only few can by the items because of high prices. IKEA tried to low down their price but still their product became luxury for the Chinese customers. In the beginning IKEA had to face many challenges. For success in business it is much necessary to understand the cultural values of the country where you are setting your business. For IKEA, to achieve the strategy goal in china means to understand the culture and socio-economic conditions of china. In terms of culture and business practices, economical and political changes in china IKEA suffered with many ups and downs. The main issue for IKEA is to understand the environment and cultural difference which influence the Chinese customer's behavior. Hofstede's Cultural dimensions Geert Hofstede had done the influential work to demonstrate the cultural differences. He identified fiv e major dimensions along which cultural values vary: high vs. low power distance, individualism vs. collectivism, masculinity vs. femininity, and uncertainty avoidance vs. uncertainty acceptance and short-term vs. long-term orientation. Difference between china and Sweden culture In china culture dominant values in society are masculine. Caring of others and the quality of people and life are not so important but the importance is given to the assertiveness, acquisition of money and things. In china society muscularity, assertiveness and challenges are preferred over co-operation and good working relationship. Another important cultural trait of china is the high power distance. This means that the distance between subordinates and superiors in china is relatively high then west. We can consider it as a shape of narrow triangle in which the mangers placed on the apex while subordinates on the base. The management is not so common or in practice. This high power distance is basically roots from the imperial tradition in china. Until 1911, the emperors were given so high value that extremely they were called the sons of god. This resulted as an unequal relationship in the society. The subordinates are restricted to obey and owe their superiors in exchange for protection and consideration (Sriramesh, vercic, 2003, p 26). The local government institutions in china are powerful and mostly they operate on discretion. This is the main

The Effect of Inflation on the Consumer and Money Markets Research Paper - 2

The Effect of Inflation on the Consumer and Money Markets - Research Paper Example The federal government realizes the impact inflation has on the elderly and in their social security system there is a safeguard protocol that protects the beneficiaries. The payments of social security are adjusted each year to offset the effects of inflation.   Another reason the elderly are affected a lot by inflation is that the elderly spend a lot of money on medical expenses. The inflation rate in the medical field is approximately 10%. The inflation varies by goods and industries. When inflation occurs in food prices the lower class is affected the most because poor people have limited income to pay to its food necessities. The amount of inflation in an economy depends on the country. In the United States, the inflation rate as of February 2011 was 2.1% (Tradingeconomics). Historically the United States has always had a low inflation rate. There are parts countries in this world that have been completely destabilized by the effects of inflation. A phenomenon in economics known as hyperinflation can destroy an economic system. Hyperinflation can be defined as extreme or excessive inflation. A country that is currently going through a hyperinflation crisis in Zimbabwe. Two other countries that have suffered from hyperinflation in the past are Argentina and Russia. In the past, the cost of living was much lower. We have heard stories about how our grandparents used to pay a few pennies for a can of coke or a pound of bread. Through the passage of time, things have gotten much more expensive. Despite lower wages, our ancestors had great wealth because they could buy more goods and services with less money. During those years owning land and homes was more accessible because prices were much lower. When inflation goes up in the United States the Federal Reserve can take measures to control inflation. This is called monetary policies. The current chairman of the FED is Ben Bernanke. Inflation is an economic variable that affects the lives of everyone. When inflation is low people enjoy a better standard of living in the long run because their money is not getting diluted due to inflation. In the United States, inflation is currently low at around 2%.
