Residual RFIDs - are these a threat - Essay Example This information has adverse threats on the person that buy the products containing these tags because the information can be used to cause harm to them when it lands in wrong hands (Cazier, Wilson and Medlin 2007). Some of these threats are outlined below. The RFID tags can be used by non-authorized personnel to track and retrieve personal information of people without their knowledge using objects containing these tags. The assessment of their belonging may lead to access to these belongings without the consent of the owner (Spiekermann and Ziekow 2005). The use of mining of data can help acquire information from RFID tags. This information can be used to retrieve and identify the social links that exist between people. This information can be used by security agents to track criminals, but it can also be used by criminal to cause harm to the people (Spiekermann and Ziekow 2005). RFID tags can also cause technology paternalism. This is the fear in people who have objects that contain these tags over the lack of control of machines’ action that cannot be overridden. This can cause punishment to owners of these objects thus intruding on the peoples live. RFID residual tags have their benefits, but the presence of threats on the lives of consumers cannot be overruled. Addressing these threats will ensure that consumers are comfortable buying products containing these tags (Gao, Xiang,Wang, Shen, Huang and Song 2004). Gao, X., Z. Xiang, H. Wang, J. Shen, J.

British Fiction Essay Example | Topics and Well Written Essays - 2250 words

British Fiction - Essay Example Both of them are distinctive, and in many ways ground-breaking plays written by playwrights who are , in their way, regarded as quintessentially 'English' or 'British' in nature: if such as thing as British literature exists, it would be found within their work. First of all is there such a thing as "being British" At the most basic level "being British" would be someone who is born, raised or who hold British nationality. In this case both Pinter and Stoppard meet this crude "British" definition. Being British is also essentially an idea rather than a reality. It can be seen as adherence to a number of supposed national norms that the British display. Eccentricity, independence, an indomitable nature, reserve, politeness, intelligence, genius, empire, arrogance are all characteristics which can be said to be 'British', and thus it can be seen to be a number of often contradictory things. 'Contradiction' is one of the hallmarks of Absurdist Theatre and thus it is apt that The Caretaker is one of the first works of drama to be written within the genre called The Theatre of the Absurd. What can be said to be particularly 'English' about this work. ... mixture of threat, comedy, hopelessness and an ironic commentary upon working class lives that are based often upon endless combative exchanges of words. The characters make fun of their situations in a manner that is both vaguely threatening and funny. For example, Mick gives an exaggerated description of what the hopelessly run-down house could be: MICK: We could turn this place into a penthouse. For instance this room. This room could have been the kitchen. Right size, nice window, sun comes in. I'd have I'd have teal-blue, copper and parchment linoleum squares. I'd have those colours re-echoed in the walls. I'd offset the kitchen units with charcoal-grey worktops. Plenty of room for cupboards for the crockery. We'd have a small wall cupboard, a large wall cupboard, a corner wall cupboard with revolving shelves. You shouldn't be short of cupboards. You could put the dining-room across the landing, see Yes. Venetian blinds on the window, cork floor, cork tiles. You could have an off-white pile linen rug, a table in... in afromosia teak veneer, sideboard with matte black drawers, armchairs in oatmeal tweed, a beech frame settee with a woven sea-grass seat... (sits up) it wouldn't be a flat it'd be a palace. (Pinter, 1998) Mick is making fun of his brother's (as well as the tramp's) ridiculous plans for the house, and goes from the reasonable to the absurd in his descriptions. Take the description of the cupboard, which soon turns into a "large wall cupboard" and then on to the absurdly ambitious "cupboard with revolving shelves" (Pinter, 1998). Pinter is also commenting upon the pretentious of the English middle-class, and those such as his brother and new 'caretaker' who would want to be one of them. The details of this pretension, seething with sarcasm as they

Employee Involvement In Organizational Development Management Essay

Employee Involvement In Organizational Development Management Essay Employee Involvement means creating an atmosphere where people have an impact on the decision making and can affect the job. It is not a term or a goal or a tool which can be practiced in a corporation in fact it can be called a viewpoint describing how one can contribute to the progress and the stable accomplishment in their job association. Because of this involvement employees are able to feel a sense of having rights and obligations through which they are able to retain their top abilities and promote an atmosphere enabling them to be more motivated and participative. How staff can be expected to get involved in decisions includes the planned facet of input and can take in such methods as idea scheme, production cells, work teams, nonstop expansion meetings, Kaizen events, remedial act processes, and intermittent discussions with the administrator. Inbuilt to most employee input processes is teaching them group efficacy, communiquà ©, and problem solving, payment systems and gai n sharing. (Heathfield, 2012) Encouraging employees to become involved: A hundred percent support cannot be projected from any person who was not himself involved in devising a change or an alteration which had an impact on his job. In any transformation, mostly ones that influence a whole group, it is not probable to engage every employee in each decision. On the other hand when change starts working; it means the association goes out of its way to manage worker involvement. Staff involvement for successful change administration creates a plan for involving people connecting everyone who will feel the force of the changes in the knowledge, preparation, decisions, and accomplishment of the change. In change management a small group of employees learn important information about change management. If they do not share that information with the rest of the workers the other employees might have difficulty catching up with them. If a small cluster makes the change management plans then the staff affected by the decisions will not have had needed time to obs erve the latest ideas. If employees are left behind a door gets opened in the change management procedure, for false impression and disagreement. Even if employees cannot affect the decision about change on the whole still they should be involved in the consequential decisions about their work unit and their work. A change process should be built that tells people when they are succeeding or deteriorating and follow up about consequences should be provided in each case. Employees who brightly work with the change should be provided with rewards. After the employees have been allowed to go through the change stages the unconstructive consequences should also be conveyed to them. Those who are resistant cannot be allowed to continue on their negative path; they will in due course have an effect on the morale of the constructive ones. The solution to this is that during the change management process an implementer should know where to say that now it is enough. (Heathfield, 2012) Relating employee involvement with company performance: According to (KAUFFMAN) , by devoting to future leaders organizations are building the foundation for success when it comes to improving worker retention as far as escalating the firms yield is concerned. A basic bottom up personnel association program is used to unite employees in the business. In order to make sure employee involvement is effective they delegate power to employees at all levels of the organization and recognize quite a few calculated initiatives through task forces to enlarge those initiatives. This practice can put plans into effect while at the same time creating an encouraging plan for the firm and can encourage the staff to construct new ideas and. The firms mission is to teach employees to offer the highest quality service to patrons and for that they need people who are motivated enough and excited about their work. They consider the idea of involvement providing mechanical preparation which drives profitability to get them mixed up in the firms dealings as w ell. Some aspects of employee involvement program and tips for starting an employee involvement plan within the firm are. Recognize the agenda scheme Generate a task force Ensure top level support Encourage and promote employee participation Keep tracking progress and keep communicating results If successful celebrate your victory Launch the involvement program Linking performance and culture transformation together? By doing so everyone can be involved in stirring up the association forward and constructing synergy and enthusiasm at all levels. By being able to advance values of input firms can join employees at all levels in the industry thus increasing competence. Capable programs can also supply opportunities for leaders of tomorrow. The dollars that are being used up in teaching employees can in fact be used up trying to engage into performance and culture transformation but how can these two be put together? Performance change initiatives are reasonable linking slow and determined attainment of skills. Culture change initiatives are zealous. They focus on modification in point of view and relationships and on the arrangement of a surrounding of truthfulness and inventiveness. (Mackin, 2005) An Employee-owner corporation chooses its own level and kind of contribution, but it must direct expectations about decisions. Employees might be expecting a definite amount of power. Organizations that can manage decision making wisely can over time strike a greater share of their human potential. Companies that do not intentionally address peoples expectations may find rising pessimism and doubt. (The Ownership Culture Report , 1998) Recognizing and dealing with barriers to change: Those resolute to arrive at brilliance come to recognize the implication of employee ownership and involvement. To be victorious in ensuring engagement, it is imperative to recognize the collective dynamics of contribution and the barriers to a participative culture. Human beings are by nature social creatures. They wish to experience a belonging sense and to be involved in something. They seek to share thoughts. They wish to partake in the common relationships that the world around them frequently promotes. If correctly guided, this combined need could be leveraged to assist organizations. This craving to bond increases with new social networking platform and technical expansion especially for youngsters. People are neurologically programmed and ethnically reinforced to share ideas. If employees do not get involved at work, they will look for other conduits to direct their imagination. Regrettably, employees are not always aware of the sharing opportunities most companies offer. (Galloway, 2010) Worker involvement as a central debate: Worker involvement has become a central debate in trade relations over the last decade. An Employer who is confronted by more and more cutthroat product markets and a greater magnitude for quality assurance and customer satisfaction must started centering concentration on attempts to enlarge and encourage employees, as well as illustrating more upon employee understanding and skill. Within the academics area, this subject has undergone a revival where researchers are inquiring whether this is really new and how it relates to HR management. (Mick Marchington, 1991) Graziers key learning points: People struggle each day with the various very real difficulties of human interaction, communication, disagreement, conviction systems, headship, inspiration and human potential, conflict to change, ingenuity, and so forth. (Grazier) Discusses what he calls the Key Learning Points as under: Everybody has things to contribute and they will if the surrounding is right. This according to (Grazier) is the effect of working with employee involvement concepts. People place limitations on other peoples understanding which is more a subliminal act than a mindful one. They usually feel that their own solutions to problems are the very best. But when they work more closely with them, particularly on front lines, they see knowledge, aptitude, skills, and resourcefulness that surprise them. Sometimes the most implausible people can come up with luminous solutions to problems. Thus they stop putting limitations on others but rather they see themselves as reservoirs of knowledge. Quoting an example a problem was being discussed with an old worker at a food company. He started discussing solutions for swiftly clearing the food material from a crammed hopper which often happened. When asked if he had ever told this idea to his manager he just smiled and said nobody asks for this kind of idea around here. This worker had spent a lifetime in the company and was retiring in a few months. How many such ideas he would be taking with him? (Grazier) The point being that people have a great deal more to present than one can realize. And if a surrounding can be constructed that is sheltered, reassuring, and encourages taking part, more of that talent will be directed toward the prosperity of the organization. When a manager fully understands this then worker participation becomes less of a function that one must perform and more of a viewpoint that one does evidently. (Grazier) The human constituent of performance is more imperative than the technological one. Organizations are a great deal of time wrapped up in the mechanical features of trade i.e. machinery, executive systems, fiscal controls, setting up, research, analysis, equipment, safeguarding, sales, supply and so on. A few are able to concentrate on motivational principals. As we talk about the implications of these questions it becomes apparent to everyone that, even though motivational principles have been taught to nearly every senior manager still whenever performance in a work group or association soars or slumps it can almost always be traced back to issues that have impacted motivation not technical issues. (Grazier) Most decisions can be radically enhanced through group effort. There are only a few reviews that have read (This person can team up well on decisions) or (This employee has a strong team building trait). More than a few supervisors have been approved over for promotion because they present a participative administration style. Victorious Managers today solve a quandary or make a choice by first looking for the opinions of others. True association can take time. But managers who persist should see their decisions improving gradually. (Grazier) Growth in employee skills: As (Green) has investigated the growth of job skill allotment using data derived from various skills Surveys. He determines the degree to which worker participation in the place of work and promotes the use of cognizance and interactive skills. He has found out that literacy, other communication tasks, and planning skills have grown particularly fast. Problem-solving skills have also become more imperative however recurring physical skills have principally remained untouched. He finds that worker partaking privileges the use of superior general skills and chipping in but substitute recurring physical tasks. A study by (Cruz, 2009) a University lecturer shows worker association programs that executives presume to add to efficacy as well as improving their record on diversity. According to investigators females and minorities are more successful and have better occupation opportunities when a self direction team or a cross training program is offered by the company. This means that companies can increase both quality and diversity at the same time with the same programs. Mostly females and minorities are stuck in low end jobs with little opportunity for proving themselves and for advancement. When companies put in place work teams and training programs, these females and minorities abruptly have more opportunities to display their skills. years of information on more than 800+ companies was able to detach the effects of independent work teams and cross preparation programs on female and minority access to management. In Cross function teams project groups from different jobs are able to m eet on regular intervals and take liability for getting the work done that has been assigned to them and thus being able to solve problems. Teams and cross training put gifted females and minority on the screen for managers and others who get to know them better and can counsel them and state their names when there is a new opening. It turns out these same programs also give new opportunities for females and minorities to stand out and get ahead. (Cruz, 2009) Managerial conversion efforts can bring about a variety of outcomes of which a few are projected for managerial survival and output while some involuntary such as susceptible stages of organizational change pessimism among employees. If we examine the role of information distribution and connection in decision making, while both these strategies have the potential to be resourceful, they rest on an imperative guess, that employees will eagerly hold on to any opportunities to become involved. (CREGAN, 2008) Understanding Organizational pessimism: Organizational pessimism is the pessimistic outlook of employees towards organizations. The main idea is that principles like genuineness and impartiality have to forgone to fulfill the interests of leadership thus leading to actions based on a hidden motive or deception (Abraham, 2000) .Recently, (Cole, 2006) defined pessimism as an evaluative verdict that stems from an individual experience. (CREGAN, 2008) This suggests that administrative pessimism can have unhelpful consequences for employees and organizations. As a result, the association that successfully manages pessimism is more likely to obtain benefits from an organizational change program. As (Bommer, 2005) pointed out that the overcoming of uncertainty toward change is mainly important because when workers have pessimism toward a planned change it leads to unsuccessful achievement and the breakdown reinforces the pessimistic beliefs. As a result, succeeding transformation initiatives are even less likely to do well. Employee involvement and equity: (Abraham, 2000) Argues that feelings of injustice differentiate worker cynics from positive employees and that open organizational infrastructure and participation may help produce a wakefulness of fairness. Furthermore, employees understanding of the association will be to a great deal affected and thus help them in getting involved and contributing to the success of the organization.

Evolution Essays - Is There a Conspiracy to Suppress Creation Science?

Is There a Conspiracy to Suppress "Creation Science"? Two Works Cited A frequent claim in creationist literature is that there is a wealth of scientific evidence to support creationism, but that secular, mainstream scientists are suppressing its publication in peer-reviewed journals. They are not giving creation-scientists a fair shake, they claim; they are being censored. The fact is that creation scientists are not even submitting scientific theories on creation for publication. Needless to say, mainstream scientists cannot censor what is not being submitted One can begin to investigate this issue by examining what the creation-scientists are submitting for publication. One of the easiest, freest and most uncensored publishing mediums is the Internet. People can post any message they desire to talk.origins, the newsgroup devoted to spirited debate between evolutionists and creationists. So do creationists submit their scientific evidence there?

Green Tea and Weight Loss in Overweight and Obese Adults

Obesity has become a growing health issue which is associated with increased risk of chronic diseases such as coronary heart disease, hypertension, type 2 diabetes, osteoarthritis, stroke, sleep apnea, and certain cancers (Auvichayapat et al. , 2008; Maki et al. , 2009; Nagao et al. , 2005). In the United States there are an estimated 72 million overweight or obese adults (as cited in Maki et al. , 2009).Currently, the most effective treatment for obesity is a combination of reducing energy intake and increasing energy expenditure, yet the most popular treatment is pharmacotherapy (Auvichayapat et al. , 2008, Diepvens, Kovacs, Nijs, Vogels, & Westerterp-Plantenga, 2005). Recently, researchers have found antiobesity effects in green tea (Maki et al. , 2009). The objective of this term paper is to depict the claim of green tea and its effectiveness on weight loss in overweight and obese adults. Review of the Literature Overweight and Obese and Weight LossThe basic reasoning of overweig ht and obese individuals is an imbalance between energy consumption and energy expenditure (Diepvens et al. , 2005). To achieve weight loss, a negative energy balance must occur and can be achieved by decreased energy consumption or increased energy expenditure (Auvichayapat et al. , 2008; Diepvens et al. , 2005). Genetics may also be linked to obesity in several ways. Genetics may be associated with susceptibility to fat storing and the controllability of food intake (as cited in Shepherd, 2009).It has been inferred that green tea may reduce body weight and increase satiety which will positively effect body composition (Auvichayapat et al. , 2008; Diepvens et al. , 2005; Maki et al, 2008; Nagao et al. , 2005). Components of Green Tea Green tea contains two major active ingredients which may be contributed to combating obesity: catechin and caffeine (Auvichayapat et al. , 2008; Diepvens et al. , 2005). Research has suggested that green tea catechins block the enzyme catechol O-methy ltransferase, thereby stimulating the sympathetic nervous system (Auvichayapat et al. 2008; Belza et al. , 2009). The stimulation of the sympathetic nervous system may be responsible for increased thermogenesis, fat oxidation and satiety (Auvichayapat et al. , 2008; Belza et al. , 2009). Green tea catechins may also contribute to increased antioxidant, antiviral, antiplaque-forming, anticancer activities, and decreased blood pressure and total cholesterol (as cited in Nagao et al. , 2005). Research has suggested that caffeine may promote thermogenesis and fat oxidation that positively affect body composition (Auvichayapat et al. , 2008; Belza et al. 2009; Diepvens et al. , 2005). Caffeine obstructs the degeneration of intracellular cyclic adenosine monophosphate, leading to increased norepinephrine release (Auvichayapat et al. , 2008). The increased norepinephrine may lead to thermogenesis and may enhance satiety (Auvichayapat et al. , 2008). Effects of Catechin and Caffeine Supplem entation on Overweight and Obese Adults Maki et al. (2009) conducted a study to investigate whether green tea catechin intake increased exercise-induced abdominal adiposity loss in overweight and obese adults in the United States.The researchers supported previous claims of green tea catechins’ positive effect on general weight loss, but further investigation was needed to conclude that green tea catechin consumption has a positive effect on body composition and abdominal adiposity. The study was a randomized, double-blind, controlled clinical trial that took place in two clinical research sites – Bloomington, Indiana and St. Petersburg, Florida. The male and female participants were of good general health and sedentary.The participants were between the ages of 21 and 65, had a waist circumference of 87 centimeters or greater (women) or 90 centimeters or greater (men), and a total cholesterol of 5. 2 mmol/L or greater. Participates agreed to consume no more than two ca ffeinated drinks a day and avoid medication or supplements that contained caffeine or catechin. The eligible participants were randomly assigned a beverage of catechins (625 mg) or a control beverage (0 mg) per day. Both the catechin and control beverage contained the same amount of carbohydrates, sodium, as well as caffeine (39 mg).Since this was a double-blind trial the eligible participants and staff were unaware of the assigned beverages. The eligible participants were asked to maintain caloric consumption, and required to increase their activity level by attending three, one-hour supervised exercise sessions a week for a total of 12 weeks. The Maki et al. (2009) study yielded 107 participates that completed the entire trial and met the set requirements. The average age of the participants was 48 years, about one-half were males (catechin, 49. 2%; control, 55. %), and most participants were of non-Hispanic white ethnicity (91%). Maki et al. (2009) found that the catechin group e xperienced (P = 0. 079) a greater loss of body weight than the control group at week 12. This supports results of other trials (Auvichayapat et al. , 2008; Belza et al. , 2009; Nagao et al. , 2005). The results of the Maki et al. (2009) study showed no difference in percentage changes in fat mass (P = 0. 208) or intra-abdominal fat area (P = 0. 125). However, total abdominal adipose area (P = 0. 013) and abdominal subcutaneous adipose area (P = 0. 19) decreased at week 12 (Maki et al. , 2009). Maki et al. (2009) concluded that catechins (625 mg/day) may have positive effects on exercised-induced loss of abdominal adiposity. Auvichayapat et al. (2008) conducted a randomized, controlled, experimental study to investigate green tea and its effectiveness on weight loss in obese Thais. The study included 60 Thai participates who were between the ages of 40 and 60 and had a body mass index of 25 kg/m2 or greater. Forty-two participates were females and 18 were males.The participants were required to have good health history with no current or prior metabolic or systemic diseases and not currently taking prescribed medication. The participants were randomized into two groups, a green tea group and a placebo group. The participants in the green tea group consumed a 250 mg green tea (100 mg catechin) tablet after breakfast, lunch, and dinner. The participants in the placebo group also received a tablet after breakfast, lunch, and dinner containing cellulose which was identical in appearance to the green tea tablets.The participants’ heights were determined by the use of a wall-mounted ruler and body weight was determined by the use of a digital scale. Body mass index was calculated by body weight (kg) divided by height (m) squared. Body fat percentage was measured by the use of a calibrated skinfold calipers. The sum of the triceps, subscapular, and iliac skinfolds were compared based on sex and age from the Jackson study to determine body fat percentage (as cit ed in Auvichayapat et al. , 2008). Resting energy expenditure was measured by the use of the Douglas bag system by indirect calorimetry (as cited in Auvichayapat et al. 2008). The air expired by the participants were analyzed by a computerized data acquisition system from which resting energy expenditure were calculated with the use of Weir’s formula (Auvichayapat et al. , 2008). Body mass index, body fat percentage, and resting energy expenditure were measured at baseline, and during the fourth, eighth and twelfth weeks of the study. In comparison, the green tea treatment group exhibited a significant difference (P < 0. 05) in weight loss during the eighthand twelfth weeks of the study as compared to the placebo treatment group.Auvichayapat et al. (2008) concluded that green tea can increase energy expenditure and therefore increase weight loss in obese Thais. Nagao et al. (2005) conducted a random, double-blind, controlled, experimental 12-week study to examine the effec ts of catechins on body fat loss. The researchers included 25 healthy Japanese men between the ages of 24 and 46 who ranged from normal to overweight according to body mass index (as cited in Nagao et al. , 2005). The 25 participants were randomly placed into two groups, a catechins group (n = 17) and a placebo group (n = 18).The requirements for the individuals were to consume 90% of the calculated energy intake requirement, to withhold from consuming large amounts of catechins, polyphenols, or caffeine, and to maintain their current level of exercise. Anthropometric measurements and computed tomography were administered by trained physicians at baseline and every four weeks thereafter for the 12-week study. Waist circumference was measured at the umbilical level while the participants were standing in accordance with the Japan Society for the Study of Obesity (Nagao et al. , 2005).The participants’ body fat ercentages were measured by the use of a bioimpedance analyzer and skinfold caliper method. Body fat percentage and lean body mass were derived from the ratio of total body weight to body fat. The skinfold caliper method utilized measurements at the lower end of the scapula and the intermediate region on the lateral side of the arm, and the sum of the two values were recorded. The measurement of fat was calculated by computed tomography. Computed tomography imaging was performed for visceral fat measurement by utilizing FAT SCAN software developed on the method developed by Tokunaga et al. as cited in Nagao et al. , 2005). The use of the FAT SCAN software, subcutaneous fat area and visceral fat area were obtained from abdominal computed tomography image. Subcutaneous fat area and visceral fat area were summed together to obtain the total fat area. The results of the Nagao et al. (2005) study showed that the reduction in waist circumference (P < 0. 01), skinfold measurements (P < 0. 05), and total fat area (P < 0. 05) was significantly grea ter in the catechin group (690 mg) than that of the placebo group.In conclusion, catechins (690 mg/day for 12 weeks) decrease total body fat and may be useful in preventing and combating obesity. Belza et al. (2009) conducted a randomized, double-blind, controlled study consisting of 12 healthy and normal weight male participants (age: 23. 7,  ±2. 6 years). Each participant was instructed to maintain their daily dietary and physical activity habits throughout the study. The treatments being analyzed were in the form of tablets containing 500 mg green tea extract (125 mg catechins), 400 mg tyrosine, 50 mg caffeine, or placebo.Each treatment was separated by a minimum of three days. The main focus of Belza et al. (2009) was to examine the compounds tyrosine, green tea extract, and caffeine, and their individual effects on thermogenesis, appetite sensations, and ad libitum energy intake. A ventilated hood that was tested weekly to ensure reliability was used to assess resting metabol ic rates of each participant. Participants were instructed to fast the evening prior to, as well as refrain from medication, alcohol, and strenuous physical activity 24 hours before respiratory assessments.A baseline respiratory measurement was acquired for each participant during the first 25 minutes of each assessment. The assessment then continued with 30-minute intervals in which respiratory measurements were recorded for a total of four hours. Each respiratory assessment for each individual was executed on the same time of day and on an identical schedule. The participants’ appetite sensations were analyzed using the Visual Analogue Scales which included subjective questions about sensations of hunger, satiety, prospective consumption, and fullness (Belza et al. 2009). Each participant completed the Visual Analogue Scales prior to the respiratory assessment to obtain a baseline measurement, and subsequently throughout the respiratory assessment. Another test each partici pant completed was the ad libitum meal. The participants were instructed to consume the ad libitum meal at a constant pace and to terminate consumption when satiety was reached.The amount of ad libitum meal consumed was used as the assessment of ad libitum energy intake. Belza et al. 2009) found that caffeine produced a thermogenic response of 6% above the baseline assessment as compared to the placebo (P < 0. 0001). No significant difference was found for thermogenic response with the tyrosine and green tea extract treatments as compared to the placebo (Belza et al. , 2009). Belza et al. (2009) stated that too small of a sample size was tested to conclude any appetite suppressant value of the treatments administered, and additional investigation with a large sample size is needed. Diepvens et al. 2005) administered a study to investigate the effects of green tea and a low-calorie diet on resting energy expenditure and body weight in overweight females. The researchers hypothesiz ed that green tea would increase resting energy expenditure and decrease body weight. The study was an experimental, double-blind, parallel-design, placebo-controlled trial including 46 overweight females between the ages of 19 and 57 and a body mass index between 25 and 31 kg/m2. All participates were of good health and moderate caffeine-users (200-400 mg of caffeine a day).Two groups were randomly assigned to each treatment: a green tea treatment (n = 23) and a placebo treatment (n = 23). All 46 participants consumed a low-calorie diet consisting of 60% of estimated energy expenditure and consumed three tablets daily (9:00 a. m. , 1:00 p. m. , 6:00 p. m. ) of either placebo or green tea (75 mg caffeine, 375 mg catechins). Diepvens et al. (2005) utilized an open-circuit, ventilated-hood system to assess energy expenditure, as well as fat and carbohydrate oxidation.Anthropometric measurements were assessed using a digital balance (body weight) and a wall-mounted stadiometer (height) . BMI was calculated by dividing body weight in kilograms by height (m) squared. Diepvens et al. (2005) concluded that there was not a significant difference between the green tea and placebo groups in reducing body weight. Diepvens et al. (2005) contributes the low thermogenic effectiveness of green tea to the low-caloric diet because of the reduction of sympathetic activity caused by the low-caloric diet.The reduced sympathetic activity reduces noradrenalin release which is partially responsible for thermogenesis (as cited in Diepvens et al. , 2005; Auvichayapat et al. , 2008). Summary In summary, the effects of green tea on weight loss may be attributed specifically to the catechins and caffeine, the active components of green tea. The researchers found that a positive correlation occurred between the consumption of green tea and energy expenditure, fat oxidation, total fat area loss and satiety which will contribute to the prevention and reduction of obesity.Although several stu dies found that there was not a significant difference in energy expenditure, fat oxidation, total fat area loss and satiety between the green tea and control groups, there was nevertheless a difference. Perhaps with the long term consumption of green tea, the benefit will be exponentially larger. It is beneficial to note that while the consumption of green tea is not a solution by itself, it can be used as part of the process for weight loss and optimizing health for currently overweight or obese adults.References Auvichayapat, P.

Police Power and Effective Policing Essay

Effective policing techniques are playing a major and an increasingly significant role with regards to keeping and maintaining peace in society. From this point of view, it seems that policing techniques are set to grow and develop in the years to come especially as the global society and community searches to develop and practice the principle of rule of law and to reform security establishments in the United States in order to recover from disagreement and conflict. Police are agents who are authorized to implement the law and to enforce social and public order by means of legally using force (http://www. tymonline. com/index. php? term=police). They are generally linked and associated with departments and agencies of the state that are empowered to observe and exercise police power of a particular state within a legal and defined area of responsibility. Police power is officially regarded as an intrinsic supremacy, controlled and limited by exclusions defined in the constitution of a state which makes it the most extensive, expansive and unrestrained certified power applied and implemented by the state (Hunter, 1994). The intent of writing this paper is to attempt to understand the idea of police power and effective policing that is being observed and exercised nowadays, mainly in the United States. Moreover, related literature about such a principle will be reviewed to better understand its concept and its role for maintaining peace and order in the society and community. Conclusions and recommendations will be generated from the existing literature. The idea of police power in English common law (1) dates back at least four centuries ago (http://www. un. org/apps/news/story. sp? NewsID=25538&Cr=UN&Cr1=police) and approximately concurs with the collapse of social order in Europe and the growth and expansion of both rural and urban areas. Police power is generally described as the ability of a state to control or standardize actions and conduct of its citizens and implement rules within its region which then includes aspects of security, safety, morality and public wellbeing. Also this kind of authority is not confined to the suppression of what is disorderly or offensive but encourages what is for the nation or state’s greatest welfare. Because the police power is the least limitable of the exercises of government, such limitations as are applicable are not readily definable. These limitations can be determined only through appropriate consideration to the subject matter of the practice or observance of that power. The police power is subject to limitations of the federal and State constitutions, and especially to the requirement of due process. In many countries, crimial law procedures have been developed to regulate officers’ discretion, so that they do not randomly or unjustly use their powers of â€Å"arrest, search and seizure, and use of force† (Walker, p. 43). Police power has a particular importance for understanding the constitutional division of power. The United States Supreme Court in the Nineteenth Century has confirmed that the national government had specific authority delegated by the constitution. However, all the undefined or specified regulatory powers rested with the states. The idea was extended in the new deal era to provide police power to the federal government under the commerce clause of the constitution, expanding it to the terms of services to promote public welfare. The United States courts are not based on a balance of interest’s principle to agree issues over police power (Walker, p 143). Controversies arise regarding the observance and practice of police power, specifically the utilization of physical means when it disagrees with the rights of individuals and states or social freedom such as the police power of American states or police violence or brutality. Since the 1960s in the United States, concerns over such matter has increased and reflected on law enforcement agencies, courts and legislatures at every level of government (Walker, p 143). Local governments and police agencies that supervise these officers in some aspects have tried and aimed to lessen or diminish some of these issues by means of community policing and community outreach programs (http://www. ncjrs. gov/App/Publications/abstract. aspx? ID=198029). This is to make the police more available to attend to the concerns of local communities by increasing diversity upon hiring, updating the training of these agents in their responsibilities to the community under the law and by improved supervision within the department or agency or by resident commissions (http://www. di. ucl. ac. uk/publications/short_reports/problem_oriented_policing. php). The United States Department of Justice will be bringing civil law suits against local law enforcement agencies which are authorized under the 1994 Violent Crime Control and Law Enforcement Act. This has obliged local agencies to create organizational amendments and changes, enter into consent decree agreements to assume such changes and will be presented to the Department of Justice to be controlled and standardized (http://www. jdi. ucl. ac. uk/publications/short_reports/problem_oriented_policing. php). Today the police power of a state embraces systems that are designed to uphold public security and convenience as well as those to support public safety health and morals. Though police power is said to be the greatest authority a state could ever gain, this type of control also has its limitations. Police powers are restricted by state constitutions. The notion of police power is utilized by federal courts which do not have power to interpret state constitutions: from the federal constitutional law’s point of view, states have universal police powers except where restricted by the federal Constitution. Because congress as a body has restricted authority granted in the Constitution, the Federal government does not have a universal police power, unlike the states. The exclusions are laws concerning Federal property and the military. Police forces also find themselves under criticism for their use of force. In this case, the police departments in the United States have devised programs such as outreach programs and further training for police officers to better review their responsibilities in the community in order to address and eventually mitigate this issue. This illustrates the effectiveness of policing in their nation. Training and further development are being planned to assure their community’s orderliness and wellbeing. However, since police power being granted to officers differs in their region or area or responsibility, it is suggested that their power or authority will be well defined and calibrated to avoid any discrepancies. Moreover, this idea may also help elevate the impression of some people in the society that some police officers are using their authority unjustly. With this is mind, a pleasant environment will be created with the use of an effective way of controlling and manipulating the citizen’s behavior.
