Secant Methods Application

SUBMITTED TO: sir sajid presentation on application of secant method April 16, 2013 MCS 1st sem ————————————————- ROLL # 31 to 40 SECANT METHOD * The  Secant  command numerically approximates the roots of an algebraic function,  f, using a technique similar to Newton's method but without the need to evaluate the derivative of  function. * Given an expression  f  and an initial approximate  a, the  Secant  command computes a sequence,  =, of approximations to a root of  f, where  Ã‚  is the number of iterations taken to reach a stopping criterion. The  Secant  command is a shortcut for calling the  Roots  command with the  method=secant  option Advantages of secant method * It converges at faster than a linear rate, so that it is more rapidly convergent than the bisection method. * It does not require use of the derivative of the function, something that is not available in a number of applications. * It requires only one function evaluation per iteration, as compared with Newton’s method which requires two Disadvantages of secant method * It may not converge. * There is no guaranteed error bound for the computed iterates. * It is likely to have difficulty if f? (? ) = 0.This means the x-axis is tangent to the graph of y = f (x) at x = ?. * Newton’s method generalizes more easily to new methods for solving simultaneous systems of nonlinear equations. APPLICATION OF SECANT METHOD 1.

Behaviour Modification Approaches In Us Public Schools

The growing need for effective procedures in disciplining and correcting undisciplined students in the US public schools has become nascent nowadays. Behaviour modification is essential in modelling young people who’ll become responsible members of the society. Effectiveness of behaviour modification procedures is seen to reduce deviance and problematic characters in a child.The effectiveness of social skills and social inoculation procedures which have blown out sub-procedures are behaviour modification methodologies whose perspective is to use culture and organizations within the social context to enforce proper moral projections in public schools. Procedures to modify behaviour have transformed from aggressive methodologies like caning, but legislation and physiological research has downplayed the effectiveness and pointed out health implications emanating from these methodologies.Expulsions, suspensions and parental advice and parent-teacher collaboration to enforce, advic e and correct indiscipline in students is an approach which is so far a commonplace practice. The need to understand these procedures, the profundity of their impacts and success in correcting and modifying behaviour in students in the US public schools is paramount and integral in the public school systems. US public schools are having problems implementing various behaviour modification procedures due to various legislation laws.There is also the growing need to identify modalities to tackle the increasing implicit character and behaviours which are negatively affecting other students in these schools. Drug abuse, alcoholism, early sex, smoking, unconventional language and outward ness towards teachers, community and other students are problematic characters seen in the students and need to be modified. This paper explores the various strategies and methodologies employed to modify these problematic behaviours and disciplining students in the US public schools. IntroductionSocial skills and social inoculation procedures have been intensively reviewed as collective and effective behavior modification procedures in public schools. These school-based strategies developed first in smoking prevention and later applied to other substances have been practically admissible due to their approach to teacher-parent and society collaboration to impart and correct irresponsible behavior in students. However, cognitive control methodologies have led to more terse approaches to disciplining and modifying behaviour in students.Suspensions and expulsions have successfully instilled discipline and positive virtues in students. A zero tolerance on indiscipline approach has now become the lead methodology applied in US public schools. Zero tolerance approach as been in force as a proactive approach to a perceived rise in gangs, drugs, and violence in United States public schools and community. Typically, zero tolerance policies mandate predetermined consequences or punishments for specified offense. These policies have been subject to debate as to whether they are effective and whether they have unintended consequences that negatively affect students.This approach has become the principle methodology in US public schools. This behavior modification approach is most often characterized by disciplinary action that punishes all students severely regardless of mitigating factors such as severity of infraction, age, or intent.. However, parents and some legislators often criticize the methodology citing consequential health implications. The need for espousing these procedures is important, especially in this wake of a huge populace in the United States. The multi cultural aspect of the community in which the populace is composed of various communities .i. e. Caucasian, blacks and Whites is troublesome due to dissenting interests and attitudes towards education and moral facade of each student from each community. According to statistics, escalation of moral d ecadency and the overt-ness of sexuality in young people is more of an intricate social quagmire and an intrinsic social problem with wide spread implications on the long term and adverse socio-economic-health implications on family and the public domain. This has been manifested in public schools wherein the behaviours and indiscipline are seen.On substance abuse and violence, teachers in school need to identify the time and place where their students engage in alcoholism. This will help in identifying proper means of creating recreational or rehabilitative timetables for these students. Drug abuse and alcoholic sprees usually happen between 3pm and 7pm (www. samhsa. gov) outside the school compound or homestead, or in the most neglected and limitedly visited areas of these two environments. The most common alcoholic substances abused are beer and spirits (www. samhsa. gov).These escalations In moral problems in students and indulgence in sexual behaviors, violence, disrespectful, bullish, and various problematic characters is increasingly affecting the level of education in American public schools. Research indicate so many youths are now unable to finish schooling due to indulgence in bad morals and problematic activities and subsequently being expelled from school while others drop out in pursuit of these vices. The need to correct and modify these behaviours and arrest any escalation of these problems n the public schools is becoming integral in the education system.Methodologies and approaches are being employed and comprehensively used to counter the situations and model students into responsible young people who are admissible in the modern American society. Besides, identifying problems in students and using the proper counselling and behaviour modification strategy is vital. Problems faced by US public school system regarding students with bad behaviour The problems faced by the public schools onset with dropping out school by students due to their i ndulgence and subsequent immersion in problematic lives like being parents or even going to jail.Secondly, students nowadays have developed various behaviours which are deemed dangerous. There is also a growing trend of students practicing and exhibiting immoral projections which do not reflect respect of upright morals and behaviours and are deemed disrespectful. According to research conducted in Baltimore, the following are the problems faced in US public schools (Brecht Donoghue , 2004) †¢ Possession, use or distribution of tobacco on school property †¢ Disruptive behavior †¢ Verbal harassment †¢ Possession of drugs or alcohol †¢ Possession of weapons or firearms †¢ Arson†¢ Vandalizing, damaging, defacing, or destroying school property †¢ Violent behaviors/assaults, vicious fighting †¢ Extortion, coercion, blackmail, and robbery †¢ Trespassing †¢ Damaging property †¢ Insubordination †¢ Dress code violations †¢ Cheating/copying the work of another †¢ Fighting †¢ Possession of electronic devices (e. g. , beepers, cell phones) †¢ Sexual harassment †¢ Sexual misconduct †¢ Verbal abuse, ethnic slurs, vulgar statements or gestures, including the distribution of obscene material †¢ Misbehavior on bus or school transportation †¢ Disorderly conduct †¢ Gambling†¢ Assault on school staff Behavior intervention approaches Frank M. Gresham (2004), argues that Behavioral interventions is conceptualized using four broad theoretical categories: (a) applied behavior analysis, (b) social learning theory, (c) cognitive behavior therapy, and (d) neobehavioristic S-R theory (Powers & Franks, 1988). Applied behavior analysis (ABA) descends directly from Skinner's (1953) operant conditioning work and is based on the three-term contingency that describes the functional relationship between antecedents, behaviors, and consequences (Gresham, 2004).Social cognitive theor y utilizes the concept of vicarious learning and the role of cognitive mediation processes in determining which environmental events are attended to, retained, and subsequently performed when an individual is exposed to modeling stimuli (Gresham, 2004 pp 327). Social learning theory is based on the notion of reciprocal determinism that describes the role an individual's behavior has on changing the environment and vice versa (Bandura, 1986). Much of the work in social skills interventions utilizes modeling as an essential treatment strategy (Elliott & Gresham, 1991; Gresham, 2002).Cognitive behavior therapy (CBT) assumes that an individual's behavior in response to environmental events is mediated by their cognitions or thoughts (327). The goal of CBT is to change maladaptive cognitions that, in turn, lead to changes in behavior. Techniques such as self-instruction, self evaluation, correction of maladaptive self talk, and problem solving are used in CBT to change behavior (Kendall, 1985). CBT interventions are commonly used in the clinical treatment of anxiety and mood (depression, dysthymia) problems (Kazdin, 1990; Laurent & Potter, 1998).Neo-behavioristic S-R models are based on features of classical (respondent) conditioning and avoidance learning in which maladaptive responses are conditioned to stimuli in the environment (Gresham pp 327). Procedures such as systematic desensitization and exposure based treatments (e. g. , flooding, implosion) for treating anxiety disorders and obsessive-compulsive disorders are based on these S-R models of learning. These concepts have been dissected into simplistic approaches by school experts and education stakeholders.They have been incorporated in the public school behavior correction faculties as methodologies whose effectiveness varies with the level of behavior intricacy and extent of effect on the respect and view by the teachers Behaviour modification methodologies used to correct this indiscipline Various moder n approaches to these problems are in place. Teacher intervention techniques as well as school rules modification approaches are also in force. These approaches differ with effectiveness and time frame of implementation. Expulsions, suspensions, caning are commonplace.They compose the zero tolerance methodology which is the common practice used in public schools. Drugs, alcoholism, language and violence are approached as cases which need to be addressed cognitively. Teacher intervention methods revolve around counselling and participating in initiating good behaviour and positive perceptions in the students who have these problematic behaviours. School teacher intervention The creation of a positive social interaction environment in a friendly and unrestrictive atmosphere offers the proper environment for the teacher to address the problem.This kind of environment greatly increases recovery. It’s aimed at improving collective social behavior so as to inspire and correct the s tudents. The school counselor should counsel the students, encourage them to share their problems, initiate recreational activities like playing chess, bridge, and other in-house games (Ken & David 2007). Through a cognitive-control system the teacher manifests self analysis, self recognition, and self help so as to regulate behavior. It involves reading materials wherein the teen reads her problem and follows a set of procedures like, playing with her pet, watching an inspiring video, etc.The procedure is used in the environment created by the school teacher (above). The objective of the method is to create competing system within the brain and make adolescents lessen brain capacity to want physical engagement with substances. A school counselor should address the teen alcohol problem through an educative perspective; He gives complete clinical views on use and abuse of substances and comprehensively emphasizes the importance of the context (David Masci,, 2000). This perspective sc ope is on teenage cases who are supposed to actively attend and play roles in the education and during the classes.The concept is to keep these teens safe from alcohol and to stop substance abuse. The school counselor should give social and drug life education to enable teenagers to make responsible decisions by providing honest information. Secondly, the student should emphatically give a complete clinical and legal overview of implications of both on substance abusers to discourage the teens from excessive or partial indulgence. The counselor is also supposed to advise the students to understand their place in the society and their future as citizens in the educative approach (Flannery, 2007).After-school programs Students tend to have various social networks where they interact. The school counselor should integrate these networks as extracurricular activities by allocating time to be with the students. According to research, drug abuse takes place mostly after school and evening hours as stated above (Bachman, Johnston & O’Malley 1990). A school counselor is involved in participating, and listening to what students express and how they relate with their peers. In a group setting, he encourages the students to speak freely, express their views, thoughts, ideas, and perspectives.He intervenes only while asking them why they feel or think a certain way, then offer his support. Students can have a friend or family member participate in order to improve the advice being offered. The setting is a homely, conducive, and well equipped with internet and all communication tools to help these students research their problem with guidance from the school counselor. This is a very effective method and creates a backbone for the gradual and even instant ceasing of alcohol habits.According to (Rosenbaum, 2003), the after school programs form the basis of a communal approach to the problem. The students are able to understand their problem through guidance. If a st udent’s drug use becomes a problem, the after-school drop-in program enables her to make informal contact with a professional, even if she is not ready for formal treatment. If problems escalate, a referral to the appropriate agency can be made (Rosenbaum 2003). Peer mediation Education experts also suggest providing opportunities for students to become more engaged in school activities.Adopting strategies that include students in the discipline process, including peer mediation and mentoring, may assist violence prevention efforts. In peer mediation, students are encouraged to sit down with a trained student mediator (often accompanied by an adult) and resolve their differences through dialogue. In many cases problems that would otherwise escalate can be resolved through mediation. However, if the problem is not solved, students may be required to meet with an adult or older student mentor once a week for further mediation and mentoring until all parties agree that the issue is resolved.Approaching the student’s problem to foster an understanding that the student is capable of excelling in all aspects of life if he/she desists from substance abuse is helpful. The school counselor should as often as possible make groups which consist of most disciplined students to act as the role models. These role model groups actively integrate with other groups and incorporate the students who have drug problems. This makes these students sociable and gradually makes them feel acceptable in these groups and most important, desists from substance abuse due to the moral aspect of the group personality status.Zero tolerance methodology These policies mandate predetermined consequences or punishments for specified offenses, especially those deemed very criminal in terms of the age and environment they are committed. Sex, drugs, violence, assault on a student, teacher, damaging school property and related cases are approached through the zero tolerance approach. T he methodology is related to substantial drop in school crimes and is common practice (Ronnie Casella, 2000). Zero tolerance is a policy that mandates predetermined consequences or punishments for specified offenses.It is intended to deter student misconduct by weeding out potential troublemakers and setting an example to others who might choose to misbehave, zero tolerance policies are most often characterized by a variety of high-tech detection methods (such as metal detectors and video surveillance) and strict discipline policies that punish all offenses equally severely without consideration of mitigating factors, such as the severity of the infraction or the intent or age of the individual (Russell Skiba, 2000.In most cases, these policies mandate that perpetrators be subject to school exclusion disciplinary actions ranging from suspensions and expulsions to arrest by in-school police (Brecht Donoghue , 2004). Great results have been seen through this methodology, however, its harsh aspects and the suspension of the student affects the educational background of a student (V. K. Costenbacher and S. Markson, 1994). Proponents of zero tolerance argue that these policies are needed to remove disruptive elements from the classroom and keep schools free of violence.Zero tolerance is implemented in cases where the student exhibits behaviors which are deemed too harsh to be contained in the school (C. Bowditch, 1993) . School student communities approach Public school administrations espouse building a sense of community within the school has been effective at preventing violence (Russell Skiba, 2000), because students are held accountable by their peers for harm they cause. Public school administrations adopted a community model in which students rectify their mistakes whenever possible.In schools these communities institute pee juries or teen courts in which students accused of misbehavior must appear before a jury composed of fellow students. The accused stude nt must explain his or her misbehavior to the jury, and then the jury is responsible for communicating to the student how the behavior violated the rules of the school community and develop an appropriate consequence (Brecht Donoghue , 2004). The student’s sentence is not punitive, but rather an attempt to reintegrate the student into the school community.Most often, the student is required to make restitution for his or her action and engage in some type of community service Decision-making and problem-solving This approach emphasizes the development of cognitive and behavioral skills which are flexible and not situation-specific. On a cognitive level, students are taught decision-making and problem-solving techniques which will better prepare them to avoid peer pressure situations without alienating friends. Students are also taught specific self-instruction techniques that are designed to provide them with a framework for guiding themselves through high-risk situations.Fin ally, students are taught basic interpersonal skills designed to enable them to implement specific decisions or act in a way which is consistent with what they want (Catherine S. Bell and Robert J. Battjes, 1984). Other measures used in US public schools Schools’ use of programmatic prevention efforts, such as conflict resolution and behavior management, help prevent student violence and aggression and eliminate the need for harsh disciplinary action (David Masci, 2000).Conflict resolution has a moderate effect on the level of student aggression in schools, and helps students remember and employ alternatives to violence when solving conflict. More support and training in classroom management of behavioral problems helps teachers deescalate potentially violent situations. Expansion of training for principals and teachers in the development and implementation of behavioral management programs to help them learn strategies useful in deescalating potentially violent interactions. This has helped more of the teachers in the public schools to have more efficiency and capacity in Expansion of violence prevention programs in schools accelerates awareness and proficiency in recognition of faulty behaviors. Introduction of school counselors in public schools is becoming a very effective methodology. As seen in the teacher intervention methodology, through a cognitive-control system the teacher manifests self analysis, self recognition, and self help so as to regulate behavior. This will help address the decline on the learned youths which is adversely affecting the social balance.More Hispanic youths, especially males, is on the declines. The effects on the society are more poor families, crime rate increase and joblessness. The long term effect is a social imbalance with Blacks and Hispanics as well as other immigrants joining the lesser society and the poor Americans. A steady decline on stable families and the many unlearned and jobless children is affecting th e national economic stability. Subsequently there will be more children, the poor and the aged in the population that the stable workers (Sandra Yin, 2007).Parents and social involvement in correction of behaviour The role of parents in behavior modification is the most integral in the public school behavior modification approaches. The parents and community members have been involved in contributing as the guardians of proper social behaviors in the community. The counselor involves concepts of capacity building and establishment of more positive youth groups so as to build on youths’ strengths. This is through advising on developing positive mental attitude towards their abilities in education and entrepreneurship.The teacher invites the community to lead in playing a role of advisors while he is the active leader. These community members and the school counselors have the obligation to present appropriate role-models and opportunities for remediation for young people growi ng up in the school community. The message to young adults and their peers must be that they understand the dangers of substance abuse and make appropriate choices when confronted with opportunities of drug use (David Masci, 2000).In expulsions and suspensions, parents are involved in these decisions which are seen more punitive and applicable as ways to correct bad morals projected by students. Effective parenting onsets good behavior and structures long term proper characters in children. This proper behaviors and morals are carried to schools where these children meet children with different characters and up-bringing. Parenting skills have led to development of approaches to train parents in skills seen as necessary for a harmonious parent-child relationship and for the amelioration of a number of childhood problem (Pinsker & Geoffroy, 1981).Parents with skills and knowledge about effective parenting have been able to address and reduce deviant child behaviours. This has also le d to harmonisation of family and school perceptions in these children. School administrators have been approaching parents to attend as often ass possible school based behaviour modification approaches to arm the parents with enough knowledge on how to manage their children and the implications of immoral and indiscipline in school. The approach has been to intensify the knowledge of parents and their capacity on how to be proficient in behaviour modification.Parents have increased their capacity in communication when discussing and reprimanding their children who show immoral characters and problematic behaviours. The public schools administrators and stakeholders have emphasised on parents to learn more effective means of dealing with typical parent-child relationship conflicts and develop a healthier parent-child relationship. Behaviour modification approach contains an emphasis on direct behaviour aims at direct behaviour change. Parent’s capacity to modify inappropriate behaviours is emphasised so as to arrest these problematic problems.Parent’s capacity, based on the training attained and knowledge imparted in the school administrators, is aimed at making the communication approach of the parents to aim at focussing upon maladaptive communication patterns between parent and child that are seen as the cause of inappropriate child behaviour (Pinsker & Geoffroy, 1981). Impact of bad behaviour on good students The impact of the bad behaviour in the well behaved children in schools negatively impacts on those students who have good moral back grounds.The consequence of these impacts are unsafe learning environments, exposure to smoking, drugs and other problems portrayed by the bad students. The students are intimidated and coerced so as to identify with these students. These impacts result to poor academic performance and profound moral decadency in the schools. Safety and correction to reduce harm and to reconstitute behavior and perception in the teens is important. The school counselor can actively and consistently provide extra attention and consideration to the teens with the problem and follow up their recovery.The impacts of bullying and coercion lead to traumas and children seeking to leave these schools due to intimidations by these problematic students.

In 1999 Asda became a subsidiary of the largest retailer in the world, Walmart. Asda operates within the UK grocery market and currently rank second. Asda's main area of business falls into the food sector and boast 500+ stores nationwide. Asda is a variety retailer stretched over numerous sectors, which include, entertainment clothing and footwear. It is considered a multi-channel retailer, with a blend of store locations and growing online presence. Asda's stores are traditionally, large purpose built units located on the outskirts of a town, much like Walmart stores in the USA.Similarities continue throughout the UK operation, with the Walmart culture permeating through stores amongst all 143000 ‘Colleagues'. Furthermore, matching Walmart's low-price operational strategy. My role within this retailer is a part time night replenishment colleague. Economic. The UK unemployment figures are an important aspect of the economy for Asda to watch as fluctuations can hugely effect su pply and demand, impacting future sales. Higher unemployment, means Asda will see a greater demand on lower priced goods.Asda promotes its self as being a ‘low priced' retailer, so, it may also be fair to expect an influx of new customers increasing demand further. Reacting quickly to a change in the economic climate can increase the chance of gaining market share. Utilising their immense buying power, Asda can demand lower cost prices from suppliers, facilitating demand from an expected shift in consumer buying. Considering international manufacturers, where the GBP proves particularly strong may also be one way of achieving higher profit margins.Social and Cultural Management considering a particular location for a new Asda store must measure the concentration of the local market and consider Social and Cultural forces. They can help determine if an area is understored and demand is present. Statistics of particular interest are likely to be, age ranges, population density, income ranges, level of car ownership and local transport links. Use of gravitational models will help determine the ‘pull’ of a store location. Huff’s (1963), is one such model and aims to predict this.The model calculates the probability a shopper is likely to visit our new store against local intertype retailers in its strategic group. Retailers within Asda’s group are likely to be Tesco or Sainsbury’s. In addition, analysing the demographic and cultural make up of the area should provide good indication of products and services best suited for our new store. For example, if our considered area had recently had a high level of Eastern Europeans settle then incorporating a generous ‘world foods’ section within our assortment would make sense.However, if the area had an very low level of ethnic diversity there would be little demand and focus elsewhere would prove more profitable. Technology. The introduction of Smart-phones in recent years has given customers power to access price comparison sites while in-store. Potentially this trend poses a huge threats for Asda â€Å"with these devices, customers have all of the power of the Internet at their fingertips to enable them to shop smarter† (Mobile Commerce Daily,2011) Potentially this trend poses a huge threats for Asda.An increase in store waste, particularly of perishable goods as well as loss of sales to rival retailers. Additional pressures to control costs, namely wages, to ensure the store remains profitable despite loss in sales. Political and Legal. Asda sell a range of tobacco products as part of their supermarket assortment. These products are usually sold from individually manned Kiosks, separate from the main store. In an effort to address the problem of young people taking up smoking, government are forcing retailers to cover tobacco products out of view with metal roller shutters.Other measures include a raise of the legal purchase age of suc h products and further tax increase on tobacco. Operationally, managers will need to establish good procedures which will keep inconvenience to a minimum. Other than the initial cost of installing the shutters, additional expenses relating to employee training costs should be considered. Furthermore, political and legal forces could negatively impact customer flow, which may lead to a dip in impulse buys (confectionery) and commission earners (lottery) sales.Both are often located at the kiosk and are add-on purchases to tobacco. Ecological. Environmentalists are keen to highlight links between waste management in businesses, global climate change and weather. Business' who manufacture, distribute and/or use products have been attributing to global warming, all processes expel greenhouse gasses which have major repercussions on the planet. According to waste legislation business' must establish ‘a system that ensures waste producers or those handling waste follow the waste hie rarchy (i. e. revention, reuse, recycling, recovery, disposal)' ( Surrey County Council, 2012) This forces business' to consider waste management throughout their infrastructure. Managers would have needed to assess the supply chain and identify areas where improvements can be made. There are likely to be initial expenses for man hours, new equipment and facilities. Very recently Asda has seen the effects of global climate change directly impact their business. Extreme weather has lead to mass flooding in areas in the UK. In these areas trade would certainly diminish while neighbourhoods recover from the disaster.Stores may also have experienced damage to buildings and stock. A further example of this force affecting Asda. In order to identify Asda's competitors, firstly I need to establish the number of other retailers and their size also operating in the same sector, food grocery. According to market share statistics, in the 12 weeks to 7 Aug 2011, based on similar sized operation , Asia’s direct competitors were Tesco, Sainsburys and Morrisons. This is highly saturated sector due to the number of large retailers operating within it. 12 wks to 7 Aug 2011 Tesco 30. 5 % Asda 17. % Sainsbury’s 16. 1 % Morrison’s 11. 7 % (guardian. co. uk[-;0], 2011) Further competition may come from retailers entering the sector. A high number of entrants may indicate the market is highly competitive, however, high levels of retailers will also leave if the competition is just too high. Kwik Save is a good example of this, ‘It struggled to make profits in the 21st century as superstore operators such as Tesco[->1] and Sainsbury's[-;2] introduced their own budget brands (wikipedia. org,2012). Kwik Save promoted themselves as a low-priced grocery retailer.Kwik Save are expected to make a return to the market this year and may become another threat to Asda as they previously operated by similar strategies. Establishing which of the competitors offer produ cts most similar to Asda's assortment will be another indicator, as the level of competition will intensify where a competitors assortment proves to be a suitable substitute to Asda's own. All four of the major grocery rivals do offer similar products and services. Asda and Tesco offer financial services and online catalogue shopping via ‘Tesco Direct' and ‘Asda Direct'.Both compete highly on price and have been known to enter into price wars in order to gain market share. They have similar target markets and operational strategies. Although, Tesco has chosen to delve into the UK convenience sector and also dipped their toe into international markets both have proven a great success. In a similar fashion Asda has expanded further into multi-channel retailing opening ‘Asda Living' stores which offer wider ranges of clothing, home ware and childcare goods. These manurers have helped differentiate the businesses.Sainsbury's and Morrison's in turn offer similar product s and also have an online presence, Sainsbury's also offer financial services. Both have partnered with retailers operating in other sectors, Sainsbury's with Homebase a DIY chain and Morrison's with Kiddiecare. com. Although Sainsbury's has introduced a recent price promise to be cheaper on ‘branded' products than their competitors, they differentiate their offering through focusing on quality. Asda has counter-attacked this by introducing lines that have been modified and re-branded as superior in taste and quality, while still low on price.How Asda might need to manage colleagues with the introduction of Climate Change Legislation. Senior Asda managers will need to establish how the legislation affects them, what changes need to be made within the business and how costly it will be. Discussions about the changes with all departments involved. HR will need to address recruitment matters, ensuring suitably skilled people are in place. This may involve recruiting from within t he business and providing the most suitable colleague with specific training.Or looking outside Asda for those who already posses adequate experience in the area of Waste Management. This may be a preferred option if the business has time constraints, although may result in higher extrinsic costs. Once a plan has been put in place, new procedures established, then information needs to be cascaded down through the hierarchy. Delivering this information via training courses which may also save on company time and money. Other benefits of this style is a number of colleagues can receive the same information at the same time, rather than individually.It is important that everyone receives the same information and it is communicated clearly for understanding. Managers can then go on to monitor colleagues periodically through appraisals. Appraisals can help assess colleagues, making sure the new procedure is being incorporated correctly into their day-to-day duties. Monitoring colleagues performance can highlight problems and identify further training requirements.

All Men Are Created Equal Essay Example | Topics and Well Written Essays - 500 words

All Men Are Created Equal - Essay Example The gamut of characters she delves in: from the LAPD Police Chief Daryl Gates to a gang member, from Korean store owners to a white juror, from a Panamanian immigrant mother to a teenaged black gang member, from beaten truck driver Reginald Denny to Congresswoman Maxine Waters along with other black, white, Asian and Latino characters: aptly portrays the myriads and pressures of a fractious age. It is interesting to note how Anna Deavere Smith resonates the theme of equality in her text with the issues of race, racial prejudice, anger, and hatred. Through characters such as Rudy Salas, Sr., the Mexican artist, she elucidates the consuming hatred of the "Other"1 in the Saidian sense of the term. In Sally's hatred against the "gringos," especially the white police officers, he is not only shown like the other inner-city blacks and Latinos who resent the treatment afforded to them by the LAPD but is made a prototype of a race which has borne the brunt of neo-colonization.   'I felt like "oh, my goodness" because it was really like he was in danger there. It was such an oppressive atmosphere (66).' That Anna Deavere Smith is more of a sociologist than a satirist is elucidated in her treatment of the issue of ethnicity in the personage of Paul Parker, the Chairman of the LA Four Plus Defense Committee. Parker's statement: ' they basically feel that if it's black-on-black crime, if it's a nigger killin' a nigger, they don't have any problem with that. But let it be a white victim, they gonna go to any extremes necessary to basically convict some black people (171).'  She points out the fallacies of a system where the abuser-abused relationship is based upon the norms of inequality. In its depiction of the anguished soul of a city and a nation in crisis, the text offers an etymological explanation of the problems of racism as it presents the discourse of race struggle in the perspectives of ethnocentricism and xenophobia.  

Managing patient on antipsychotic medication Essay

Managing patient on antipsychotic medication - Essay Example Since that decade more than twenty of the antipsychotic agents have been introduced in United States. The antipsychotics used during the 1980s are collectively called conventional antipsychotics and the drugs that were introduced in the 1990s are called the atypical antipsychotics. Antipsychotics, unfortunately, have the tendency to be misused if the practitioner has sound knowledge about the psychopharmacological aspects of the drugs. Elderly patients are also at an increased risk of developing drug-induced motor or movement disorders as compared to the younger population (Saltz, Robinson, & Woerner, 2004). It is crucial to understand the pharmacological aspects of the antipsychotic drugs as improper management can lead to adverse drug reactions, drug-drug interactions, drug resistances and poor patient compliance. The second generation antipsychotics (SGA) are different from the first generation antipsychotics (FGA) because they also block the serotonin receptors. SGAs also have lesser extrapyrimidal symptoms as compared to the FGAs, however, SGAs ae associated with an increased risk of obesity, hyperglycemia and hyperlipidemia. According to studies only two SGAs cloazipine and olanzipine has been proved to be more effective than the FGAs. Antipsychotics are approved by the FDA for use in schizophrenia as well as some other psychiatric conditions and non-psychiatric disorders. They are also indicated in the treatment of bipolar disorders, autism, generalized anxiety disrder, major depressive disorder, perioperative nausea, preoperative restlessness, severe behavorial probles, severe nausea and vomiting, and refractory tourette syndrome and for the management of neuropsychiatric symptoms of dementia (Moore, DeJoseph, & Simmons, 2014). Both SGAs and FGAs are associated with risk factors and it is important to carry out a detailed assessment of the patient

Management and Leadership Essay Example | Topics and Well Written Essays - 1250 words - 1

Management and Leadership - Essay Example This essay discusses and analyzes the importance of corporate social responsibility and personal values such as instrumental and terminal values, ten ethical principles of such corporations, corporate philanthropy and others learnt during the management class. These concepts described in th essay are applied and incorporated in the answers to different questions of the case â€Å"The Housewife Who Got up off the Couch†. In the case â€Å"The Housewife who got up the Couch†, the concept of enlightened self-interest becomes evident when Eleanor Josaitis started supporting Martin Luther King and human rights activists. The researcher have concluded in the essay that the terminal values of Eleanor Josaitis are ‘a comfortable life, ‘a sense of accomplishment’, ‘a world at peace’, ‘Equality’, ‘Freedom’, ‘Happiness’ and ‘Social Recognition’. The researcher also describes the work of Focus: Hope organization with more than 500 employees and a large pool of volunteers who value altruism and philanthropy and who are involved in self-sacrifice for the sake of humanity. In addition, it is stated that ethics and moral behavior is, however, essential to reach the pinnacle of success because it always pays in the long run. Whereas, to conclude those who pay more attention to short-term gains through crimes and violation of ethical principles suffer losses like the great Martha Stewart whose indulgence in ‘insider trading scandal’ dilapidated her career and her phenomenal business achievements.

The selection process Essay Example | Topics and Well Written Essays - 1250 words

The selection process - Essay Example This is the list of requirements an employer should have at least in order to qualify for the job. This is an overview of the abilities and characteristics one must possess to adequately perform the job. Similarly, a job description list is also prepared to explain what the job is all about, including the specific duties and responsibilities for that particular position.[2] In this case, a marketing project manager supervises projects based on quality, time-schedule and budget. Please refer to Appendix A and B for a complete list of job descriptions and specifications. To hire employees, organizations have different methods of recruitment or attracting probable employees. This is time and cost-consuming and should be therefore done efficiently and effectively.[1] Job advertisements must be put somewhere where they are noticed and easily accessed. According to the 2009 Recruitment, retention and turnover survey report in United Kingdom, The top three most used methods of attracting ap plicants are through the organization’s own corporate website (78%), recruitment agencies (76%) and local newspaper advertisements. However, other means of reaching the target group include specialist journals/trade press, employee referral scheme, links with schools/colleges/universities, search consultant, commercial job boards, physical posters/billboards/vehicle, radio or TV advertisement, and social networking sites (such as Linkedln). [3] The proposed design of the job advertisement for the position of Marketing Project Manager (Figure 1 and 2) can be placed or uploaded to the company’s own website via the internet. Since the people of today rely most, if not all of their activities in the internet, it will be best to post it there. Also, if the position is not only open to the natives of the country, citizens of other nations can access it readily since internet caters to everyone else around the globe. Every organization is challenged to keep pace through the f ast changing technology and environment of today. These multifaceted features of the internet should be seen as an opportunity for better communication and utilized for the benefit of the organization. Another applicable way is to publish the job advertisement in local newspapers. It is indeed less costly to buy a newspaper than secure an internet connection most especially if an employee comes from low-income groups. There in the classified ads section of the newspaper list hundreds of job ads open for hiring. There’s a big chance that people scan or read through these pages. After the different recruitment methods are employed, decisions on the selection process is next to be made. When it comes to applicant selection, competency-based interviews are the most common selection method (69%). Ranked second and third are the more traditional methods of interviews – following the contents of a CV/application form and structured interviews (panel). Others include tests for specific skills, general ability tests, literacy and/or numeracy tests, telephone interviews, personality/aptitude questionnaires, assessment centres, group exercises (for example role-playing), pre-interview referencing, and online tests selection.[3] Normally, the selection process involves some or all of the above-mentioned activities. For the example given on the Marketing Project Manager position, it is recommended that aspiring employees undergo three stages. First is the filling of the

International Brewing Industry - Case Study Example The recommendations advise that the Danone Group should refrain from significant investments in Brasseries Kronenbourg, and monitor the performance, as to see if there are any improvements in closing the gap on their financial weaknesses and able to move out of debt over a period of time. The following report has demonstrated a knowledge and understanding of the range of techniques and concepts introduced in the Certificate in Management Studies programme. The Integrated Case study is based on the International Brewing Industry, Danone Group and Brasseries Kronenbourg. The structure of a business group is largely dependant on the strategy it follows. (Chandler, 1990) There are business groups with large degrees of autonomy among departments, and there are businesses with strict vertical management. The structure of Danone Group is observed below. Organizational structure of Danone Group allows certain degrees of autonomy to its departments/subsidiaries. The 'Premier Rond' only determines general objectives, which must be achieved, but all the local operating decisions are left to general managers of departments/subsidiaries. These companies are restructured only if their management fails to achieve the objectives determined by the 'Premier Rond'. Restructuring activities as well as monitoring performance of 'Troisieme Rond' are performed by division managers or 'Deuxieme Rond'. In this way Danone Group achieves a certain degree of autonomy at the same time

2pg response to a cultural experience Essay Example | Topics and Well Written Essays - 500 words

2pg response to a cultural experience - Essay Example India and Pakistan share almost similar cultural roots and most of the cultural practices are same and they tend to show the same kind of emotions and sentiments while interacting with people outside their own culture. One of the most striking things about this particular culture experience would be the fact that Pakistanis and Indians tend to share the same level of attitude towards life. They are not so disciplined as most of the people in west tend to be because their life is mostly haphazard in nature without any concrete planning in their life. The most important thing of my cultural experience with them was the fact they tend to view and honor women in more formal way as compared to the western people. Their respect and attitude towards women is entirely different as most of them are shy at disclosing their emotions and sentiments to them. Mostly you would find them shy and uncomfortable while talking to women. Their dresses are mostly comfortable and they prefer to wear cloths which provide more comfort than style. This distinguishes them because sometimes you may find them little bit more informal than usual as compared to Western people. My overall cultural experience has been excellent as it has been a learning experience for me. This is because of the fact that I have been able to learn an entirely different attitude towards life as whole and little things in general. India and Pakistan give you an excellent cultural experience to live and experience a culture which is more hospitable, little bit less tolerant, strict in it core beliefs as well as values and give a lot of attention to more closer bonds between

Feminism in American Cinema Essay Example | Topics and Well Written Essays - 1250 words

Feminism in American Cinema - Essay Example One meaning is "films made by women" and the other meaning is "films made for women" (p. 27). The first pat of her article attempts to explain how each field within these traditional definitions was transformed by feminism over time, using the "woman at the keyhole metaphor" to show how women gained status from being objects of voyeuristic curiosity and into the curious voyeurs themselves. As Mayne argues (p. 28), there is a need to consider "what relationships women have had traditionally and historically, as filmmakers and as film consumers, to the medium" in order to "understand how women make movies". Nothing could be farther from the truth, but this one-sided argument founded on masculine logic hides a basic natural fact: that men and women are different, and thank heavens that they are, and that women and their feminist representation in cinema would be a constantly evolving and a permanently complex and elusive goal. Mayne explains (p. 33-34) that while it is true that having women at the other end of the keyhole is a typical sign of masculine voyeuristic tendencies, it is also true that women love being seen, watched, and admired. They want to feel and look beautiful, not for any reason or motive that is a sign of inferiority, but because that is how they are wired, and nothing is bad about that. It is only "not good" if such a natural human tendency is associated with a (blonde-haired or beautiful-faced) lack of intellectual capacity. This knee-jerk subjective reaction, no matter how one looks at it, and whether it is applied to women or men, is more a reflection of the one who makes rash judgments based on looks and appearances and not based on interior substance. Women are the ultimate dialecticians, Mayne declares, recalling Ruby Rich (p. 40), who declared that "for a woman today, film is a dialectical experience in a way that it never was and never will be for a man under patriarchy". Like Brecht's ultimate dialectician who lives the tension of two different cultures, "women bring into the movie theater a context and a certain coding from life outside the theater". This is perhaps the reason why women love different films in different ways, and why some films made by and for women reach their audiences in unique ways. Feminism in cinema has certainly shaped the way actors act and filmmakers - both men and women - do films, making the human experience richer and more sophisticated. This is good for all, not only for men and the patriarchy to understand women a bit better, but also for women to better understand themselves and how they look at the world. Making, watching and critiquing movies are, indeed, different and complex (p. 41-42), and reflect the innate and natural differences between men and women that provide the artistic cinematic world a dialectic tension that contributes to its magic. Mayne's ambivalent view of women's cinema is carried over to the definition of the feminine aesthetic by de

What is the Origin of Christianity Identification and Discussion of Essay

What is the Origin of Christianity Identification and Discussion of Issues - Essay Example . . the most powerful moral lever that has ever been applied to the affairs of men† (pp. 28–29). There is no denying that Christianity has wide-ranging effects on the history of man. It has been an important force that shaped culture and society. This paper aims to look at the history of Christianity, in order to determine how it changed society and culture at its period of establishment. Through the use of the Bible and historical documents, the researcher hopes to create a picture of society of the period covered by the period covered by the Holy Book, in order to understand the context of Christianity’s introduction. This research hopes to identify why and how Christianity became a source of development in the Western world. Moreover, through the use of biblical and historical text, the researcher can determine why Christianity was instituted in the first place. By gaining an insight as to the purpose of Christianity, this research can pose some recommendations on how the thousands of Christian denominations found in the world today can work together and bring about lasting change. This research aims to rediscover the Christian legacy and help Christian denominations fine their common heritage in order for them to face the challenges of the future.This research also hopes to understand why the Western world is now in the process of abandoning its Judeo-Christian tradition and determine whether such a move is beneficial or harmful for development. Significance of the Study/Significance to Reader As has been mentioned in the previous section, Christianity has been a major force of change in history. While a study of history shows that the effects of Christianity has not always been positive, it is also true that many values such as freedom and equality would not be present today. In R.R. Palmer’s words: It is impossible to exaggerate the importance of the coming of Christianity. It brought with it, for one thing, an altogether new se nse of human life. For the Greeks had shown man his mind; but the Christians showed him his soul. They taught that in the sight of God, all souls were equal, that every human life was sacrosanct and inviolate. Where the Greeks had identified the beautiful and the good, had thought ugliness to be bad, had shrunk from disease and imperfection and from everything misshapen, horrible, and repulsive, the Christian sought out the diseased, the crippled, the mutilated, to give them help. Love, for the ancient Greek, was never quite distinguished from Venus. For the Christians held that God was love, it took on deep overtones of sacrifice and compassion. (as quoted in Williams, 2012) As the world forges its way to modernity, the value of religion and Christianity is slowly being degraded. The West, the very recipient of the change and development brought about by the introduction of Christianity is abandoning its Christian legacy as horrors made in the name of religion (i.e. the Crusades, I nquision, black slavery, etc.) come into light. It is true that the formal church is (as represented by the Papacy) has not always been a positive influence for social change. As more and more people reject the value of God and the divine, it is important for believers to merge what they know about Christianity and the facts of history in order to fortify their belief. It is no longer possible for believers to disregard the crimes made in the name of Christ. The study is important because it provides a scientific understanding of Christianity and its context. It also tries to determine the purpose that Christianity served in human history, provides and insight into the future role of

The Difficult Justice of Melville and Kleist Essay Example for Free

The Difficult Justice of Melville and Kleist Essay According to many scholars, Billy Budd is the archetypal story of good vs. evil, the injustice of an imperfect world, and the impossible decisions good people are forced to make. On a first reading of the story, Captain Vere appears to be a symbol of merciless justice, cold efficiency, and the power of the State; a godlike figure with the power to take life when and where he sees fit. The captain, whose name is loosely translated as Truth, is caught in the middle between the two. He is fond of Billy, because of his friendly open nature. He dislikes Claggart because he instinctively feels that he is evil, â€Å"No sooner did the Commander observe who it was that deferentially stood awaiting his notice, than a peculiar expression came over him. It was not unlike that which uncontrollably will flit across the countenance of one at unawares encountering a person who, though known to him indeed, has hardly been long enough known for thorough knowledge, but something in whose aspect nevertheless now for the first provokes a vaguely repellent distaste†(Chapter 19, Melville). Vere appears to have an intuitive knowledge of what is right and just, which makes it all the more baffling why he chooses to disregard what he knows is right in favor of the expedient. Martin Greenberg, in â€Å"The Difficult Justice of Melville and Kleist,† cites two arguments for Vere’s decision to punish Billy: first, is the loss of free will that follows enlistment in the Navy; second, the fear of mutiny and chaos is extremely compelling to a high ranking official like a captain (4). Greenberg and Melville understand Vere’s predicament as a man of the military. Had he been soft, perhaps more lives would have been lost through mutiny, and the cohesion of the Royal Navy might have been destroyed. The story is set in 1797, following the American Revolt against the Crown. In such tumultuous times, any form of clemency—especially in the armed forces—would be seen as a weakness for the unscrupulous to exploit. The story of false accusations against an innocent has a long history in the literary, Biblical, and historical traditions. Quite often, the person in charge of making such life or death decisions is either unable or unwilling to do the right thing (i. e. Pontius Pilate). Pontius Pilate and Captain Vere have both sent innocent men to their deaths for fear of social unrest, or an end to the status quo. In the realm of ethics, their action would have been unconscionable, but in politics, leaders must abide by the Macchiavellian dictate to When Vere calls upon Billy to answer his accuser, he believed that he would be quickly exonerated because there is nothing in his nature that would give credence to such an outlandish allegation. Until Billy strikes Claggart dead in a fit of incoherent rage, In Martin Greenberg’s analysis of Billy Budd, he remarks on the Biblical imagery immanent in the descriptions of John Claggart and Billy Budd, The two of them are the great forces of light and dark in the miniature universe of the ship, â€Å"And that world provides, like the great world itself, a Satan, harsher than his harsh name of Claggart, as sinisterly handsome as Billy is angelically—modeled on Milton’s Satan, despairing like him, but ignoble†(5). One of the ironies in examining this supposed lack of free will, is that it is an ineffable part of the Christian doctrine; yet those that are obedient to this higher power often feel compelled to perform actions they never would have dreamt of doing. Melville makes frequent allusions to Abraham and Isaac, with respect to Abraham’s near sacrifice of his son on the mountainside. Greenberg remarks upon this likeness at length in his analysis, â€Å"The two are imagined as embracing like father and son, like Jacob and Isaac, in the privacy of the sailor’s confinement, where as if it were a sacred precinct, the storyteller doesn’t venture to enter. Each experiences a sacrificial exaltation: Billy, sacrificing his life at the behest of the father-god of his world, exclaims â€Å"God bless Captain Vere! † just before he drops from the yardarm; the Captain, as the one who condemns to death, makes even the harder sacrifice (according to the narrator at the behest of his father-god the King†(5). With the death of Claggart, Vere argued for Billy’s death in a military court. The officers present knew that he was innocent of mutiny and homicide. He did not have the mental capacity to engineer such a coup, nor was he aware of his own strength. All he wanted to do was stop the lies coming out of Claggart’s mouth, and he reacted physically since he was unable to do so verbally. Would it not be a crime to kill someone that is mentally handicapped and too strong for his own good? Would it not be better to set him ashore in England or the Americas, then restore order to the At the beginning of Chapter 23, when sentence was to be passed upon the approved, the narrator presented a rather sympathetic portrait of Captain Vere, â€Å"The austere devotee of military duty, letting himself melt back into what remains primeval in our formalized humanity, may in the end have caught Billy to his heart even as Abraham may have caught young Isaac on the brink of resolutely offering him up in obedience to the exacting behest† (Melville). Like Christ, Billy had done no wrong, and perhaps this very perfection makes him less sympathetic than Captain Vere to Melville. As fallible human beings, some have more power than they know how to wield, and some decisions come at the price of the soul. It is Greenberg’s contention that the supernatural powers of the one true God, a pantheon of gods, heaven, or angels are no match for earthly injustice. The crucifixion of Jesus, the execution of Billy, and the avenging of Claggart substantiates this cynical world view.

Literature Review Of Load Shedding Methods

Literature Review Of Load Shedding Methods In chapter 1, a brief discussion about active distribution networks was presented. The importance of operation of islanded distribution networks was discussed. This chapter is intended to give the reader a better understanding of the load shedding methods currently applied and proposed over the years. However, it is assumed that the reader is familiar with basic power system engineering. In section 2.2, the area of probability of islanding and the need for load shedding is discussed. To achieve this objective, existing load shedding methods are reviewed to understand their working principle, requirements, advantages and limitations. The main categories identified are the following (i) Manual / SCADA Load Shedding (ii) Load Shedding using thresholds, (iii) Adaptive Load Shedding, (iv) Intelligent Load Shedding and (v) Load Shedding Based on Static Optimisation which are described and discussed in sections 2.2 through 2.7 respectively. Finally a summary is given in section 2.8 from which a new load shedding method for an islanded distribution network able to address the limitations of existing methods will be proposed. probability of islanding There is by now a considerable amount of literature on load shedding. That most of the literature however deals with large interconnected systems. For smaller systems when a loss of mains / grid event occurs the islanded distribution network have different operating characteristics and restrictions that require different load shedding guidelines. These are due to the low inertia of the distributed generators, the limited spinning reserve and limited communication systems [0] [0]. Load shedding is a practice used power system and serves as a function to try to arrest any frequency or voltage drop when a fault isolating part of the distribution network occurs. Faults in power systems are inevitable, for various reasons such as adverse weather conditions, ageing and failure of equipment, accident, and animal contact. In general, faults happen when an abnormal physical contact occurs between lines or on lines to earth that create a short-circuit path. If the system is not well protected, the high fault current due to the short-circuit path can cause damage to the equipment in the system. Faults also affect the reliability and quality of the power supply, leading to power interruption by frequency and voltage collapse and voltage sag events. Regardless of the interruption period, the losses are often enormous both to the customers and power utility companies. There are two types of fault, determined by the physical nature of the short-circuit path: temporary or permanent. Common causes of temporary faults on overhead lines are lightning strike resulting in a flashover of the insulator; bird or animal contact; and momentary contact due to wind or trees. Faults caused by these events exist for a very short period of time. On the other hand, a permanent fault remains in the system until the short-circuit path is removed. Common causes of permanent faults in power system networks are cable insulation failure, objects falling on the overhead lines, dirt on insulators and lines falling to the ground. When faults occur, a protection device operates to isolate the faulty line from the rest of the system (loss of mains / grid). The generators designated to provide voltage and frequency control will respond to control the island voltage and frequency. In order to achieve smooth transition to island operation, the generators must firstly ride through the fault or failure and secondly act to balance the active and reactive power in the islanded network. With a carefully designed load shedding method the operation of the islanded distribution network might be possible. It is important however that the design of the load shedding method is designed on the understanding of the characteristics of the system involved, including system topology and dynamic characteristics of its generation and load. A poorly design method may be ineffective and eventually lead to total customer interruption. Over the years, however, utility experience and extensive studies on a number of systems have resulted in different methods guidelines. In the following section, principles and guidelines for load shedding methods are reviewed. manual / SCada Load Shedding Manual or operator initiated load shedding [0] is not a reliable method to be used to avoid frequency deviation. However it can be used by some utilities to manually shed load or open ties (interconnectors) with adjacent areas at a frequencies below automatic underfrequency thresholds. This type of action might be necessary to prevent any further frequency deviation and to recover the frequency back to the nominal value. This load shedding scheme cannot be used for the islanded distribution network as it will be very slow as the frequency and voltage in the network will collapse within few seconds making it impossible for the operator to decide the correct defence action required for safe operation. automatic Load Shedding using thresholds An automatic load shedding for transmission system using different schemes such as underfrequency, undervoltage and combinations of the two can be employed to avoid frequency or voltage collapse during a significant imbalance between generation and load. These types of load shedding methods are very dependant on off line studies of the systems dynamic performance and only consider the greatest probable imbalance between generation and load. These methods have to be coordinated with the protections of the generating units, shunt capacitors and other automatic actions that occur in the system during frequency and voltage variations. Underfrequency load Shedding The underfrequency load shedding scheme as explained in the following papers [0] [0] uses relays detecting the systems frequency. These are designed to operate on the instantaneous frequency value where they trip when the frequency drops below the set point of the relay. The shedding is accomplished in the systems distribution or transmission stations where major load feeders can be controlled by tripping of the circuit breakers (CB) automatically. Different settings can be applied in these load shedding schemes. Multiple stages can be used in the scheme [0]. The substation loads can prioritised and grouped according to the importance of the load. The relays can be set to control one or more groups of loads and when there is a frequency drop these can be disconnected sequentially where the group with the highest probability being disconnected the last. Each group disconnected should contribute to the system rate of change of frequency decline. If the load to be disconnected is small compared to the overall imbalance then the contribution will be insignificant and would cause further problems to the systems frequency decline. Another setting usual for this type of scheme is the time delay [0]. The time may can be required and used usually to avoid any frequency transient dips that could arise in the system. The time delay also avoids unnecessary load shedding by allowing the load / frequency controls in the system to respond to the frequency deviation. However load shedding performed with long time delays should be set appropriately as it will make the system more vulnerable to system stability if eventually load shedding is required. This method will work adequate in a situation where the system frequency decline is slow. For example, as discussed in [0], in the UK as stated in the NationalGrids GridCode each transmission area has to disconnect a defined percentage of the peak Demand that each Network Operator whose system is connected to the GB Transmission System shall disconnect by low frequency relays at a range of frequencies. The defined frequencies and the amount of loads are given in Table 1 -1. Table 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ1: Load Shedding Scheme employed in the UK Frequency (Hz) % Demand disconnection for each Network Operator in Transmission Area NGET SPT SHETL 48.8 5 48.75 5 48.7 10 48.6 7.5 10 48.5 7.5 10 48.4 7.5 10 10 48.3 48.2 7.5 10 10 48.0 5 10 10 47.8 5 Total % Demand 60 40 40 The percentages in Table 1 -1 are cumulative such that, for example, should the frequency fall to 48.6 Hz in the NGET Transmission Area, 27.5% of the total Demand connected to the GB Transmission System in the NGET Transmission Area shall be disconnected by the action of low frequency relays. A significant drawback of this method is that the systems frequency must be already be low before the relay can operate which can delay the load shedding action and the frequency recovery of the system. Additionally these types of schemes usually shed more than the required amount of load. Undervoltage load Shedding Undrevoltage load shedding method has been successfully deployed in transmission systems to protect them from voltage collapse [0] [0]. System studies are required to determine which systems are potential candidates for suitable the undervoltage load shedding method. This method is most useful in slow decaying systems where the undervoltage load shedding relay time relays can coordinated accordingly and operate to alleviate the system from overload conditions and low voltages. Voltage collapse can be studied using steady state simulations for the identified areas using a power flow analysis. System planning engineers conduct numerous studies using P-V and Q-V as well as other analytical methods to determine the amount of load required to be shed to preserve voltage stability under different disturbances. Dynamic simulations can then determine the speed of the collapse and load shedding settings. An example as discussed in [0] in the US in the Puget Sound area, which is prone to voltage collapse has been studied. The voltage trip thresholds were determined from the results of steady state simulations of worst contingencies. The time delays for the relays were coordinated to address control actions of the automatic capacitor switching, generator limits, on load tap changing transformer using dynamic simulations. Table 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ2: Load Shedding Scheme employed in the US Voltage (pu) Time delay (s) % Demand disconnection for Network Operator in Transmission Area 0.90 3.5 5 0.92 5.0 5 0.92 8.0 5 When the monitored bus voltages fall to 0.90 pu or lower for a minimum of 3.5 s then 5% of the load is disconnected. Additionally another 5% of load disconnection should occur when the voltage falls to 0.92 pu or lower for 5.0 s. There limitation associated with proper application of undervoltage load shedding is the location of its application.to where the relaying may be appropriately applied. If it is placed on a distribution line the effects of auto tap changers mask a system overload condition from the relay, or alternatively a line switching operation or the startup of a large industrial plant on one feeder could fool the relay. The relay would not be appropriate at locations directly adjacent to generation powerful enough to control bus voltages even during severe overloads. The relay is best applied to locations with fairly stiff voltages under all normal conditions, so a low voltage condition will reliably indicate a severe overload condition, as may be assumed to be the case at large substations associated with bulk power transmission lines and therefore this method cannot be effectively applied in islanded distribution networks where DG unit power and load demand varies. combination load Shedding In order to increase the security of the above discussed methods for underfrequency load shedding the relay could be set up to supervise the voltage, the current or the rate of change of frequency. According to their combined settings, the relay could either be blocked or initiate tripping of the CB to avoid any misoperations. One combination load shedding scheme is to use an underfrequency load shedding relay with voltage supervision. Basically the operation procedure of load shedding is blocked from operating unless the voltage is below a given threshold. The underfrequency relay will be able to trip the CB as long as the bus voltage it is monitoring is lower than a set point. Another combination is to use current supervision instead of the voltage. The purpose of the current supervision is to select which feeders to trip. This can achieved by monitoring which feeders are loaded above a certain point and then the relay will initiate the load shedding signal. An alternative is to use the rate of change of frequency for supervision [0] [0]. During a disturbance the supervision of the rate of change of frequency can block the tripping for very fast frequency changes but would allow for typical frequency decay rates. Also instead of measuring the instantaneous rate of change of frequency supervision is to use the frequency change trend. In other words by monitoring the average rate of frequency change will provide a more secure decision for tripping during disturbances. The load shedding decision of the scheme is made by monitoring the frequency change over a specified amount of time usually few hundred milli seconds. Therefore making the operation of the relay slower than the ones employing the rate of change of frequency. automatic ADAPTIve Load Shedding Adaptive control involves updating the amount of load to shed used by the method to cope with the fact that the conditions such as the power imbalance between generation and load of the system are time-varying or uncertain. It is important in these circumstances to minimise consumer disruption through proper design of the load shedding arrangements. An adaptive load shedding, is based on the relays reacting to a disturbance either by being instructed the amount to shed or by having certain defined criteria based on the rate of change of frequency. Anderson and Mirteydar in [0] present an adaptive methodology for setting of underfrequency relays that is based on the initial rate of change of frequency at the relay. The frequency performance of the islanded is represented by a linear system frequency response as shown in Figure 1 -1 and presented in more detail in the literature in [0]. Figure 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ1: Simplified frequency response with disturbance input where: H = inertia constant (s) FH = fraction of total power generated by HP turbine TR = reheat time constant (s) Km = mechanical power gain factor R = droop characteristic (pu) D = damping factor Clearly the only observed quantity that gives any clue as to the size of the disturbance is the initial slope of frequency decline. The use of the initial slope to estimate the magnitude of the disturbance requires that every substation in the island will observe slightly different slopes and will therefore shed load based on different estimates of the disturbance. However on average the system as a whole will shed approximately the correct amount of load. To set the parameters for the relays as explained they are based on a simulation of the frequency response for the system. In the example given (H = 3.5 s, FH = 0.3, TR = 8.0 s, Km = 0.85, R = 0.06 and D = 1) the evaluation of the frequency and its slope against different amounts of disturbances are given in Table 1 -3. Table 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ3: Initial Slope and Maximum Deviation vs Upset (frequency nominal 60 Hz) Pstep df/df ΆÃƒ Ã¢â‚¬ °max fmin pu pu/s Hz/s Hz Hz -0.2 -0.0286 -1.7143 -1.6438 58.356 -0.3648 -0.0521 -3.1260 -3.0000 57.000 -0.4 -0.0571 -3.4286 -3.2876 56.712 -0.6 -0.0857 -5.1429 -4.9313 55.069 -0.8 -0.1143 -6.8571 -6.5751 53.425 -1.0 -0.1429 -8.5714 -8.2189 51.781 The lowest frequency permitted in the system is 57 Hz from the nominal 60 Hz. Therefore when a magnitude greater than -0.0521 pu/s is observed load shedding must be triggered. This method relies on the fact that the amount of load shedding is a function of only the inertia constant and the observed slope. The inertia constant is the rotating kinetic energy of all units in the island divided by the total connected volt ampere rating of the units. This parameter has to be estimated. Therefore, the initial slope is the only unknown. The load shedding amount is computed in per unit, which makes it easy to apply to every load and to every load shedding relay. A positive is that communication is not required between relays and the boundaries of the island are not required to be known. However the drawbacks are that if it is applied for the islanding application of islanded networks this might not be possible as the method needs good estimates of the inertia of the system D, R, TR, Km and FH. This can significantly change with the varying DG units and loads in the distribution network. Another adaptive load shedding method presented by Terzija in [0] uses similarly as the previous method a variation of the typical swing equation. Due to the dynamic responses of turbines, governors, other control actions, spinning reserve, loads are not taken in account in the calculation of the required amount of load to be shed as given in . Where H is the inertia constants and assumed to be known in advance to the disturbance. The adaptive approach is based on real time estimation of fc (frequency of equivalent inertial centre) which is proposed to be calculated centrally by measuring the local frequencies at each generator. The proposed method assumes that the time constants in the power system are large and with modern communication this method would be possible for big power systems. However in distribution networks communication is believed not to change drastically in the near future making this application difficult to implement. This is because the estimation and control information are evaluated after the disturbance occurred. Van Cutsem and Otomega proposed a method in [0] which relies on a set of load shedding controllers distributed over the region susceptible to voltage instability. Each controller monitors the bus voltage and act on a set of loads located at that bus. Each controller acts when its monitored voltage falls below some threshold and trips at different time according the severity of the drop. The action can be repeated until the voltage is above the threshold voltage. The principle of operation of the controller is described as follows. The delay à Ã¢â‚¬Å¾ depends on the time evolution of V as follows. A block of load is shed at a time t0 + à Ã¢â‚¬Å¾ such that: where C is a constant to be adjusted. This control law yields an inverse-time characteristic: the deeper the voltage drops, the less time it takes to reach the value C and, hence, the faster the shedding. The larger C, the more time it takes for the integral to reach this value and hence, the slower the action. Furthermore, the delay is lower bounded: to prevent the controller from reacting on a nearby fault. Indeed, in normal situations time must be left for the protections to clear the fault and the voltage to recover to normal values. Similarly, the amount ΆPsh of power shed at time t0 + à Ã¢â‚¬Å¾ depends on the time evolution of V through where K is another constant to be adjusted, and ΆVav is the average voltage drop over the [t0, t0 + à Ã¢â‚¬Å¾]interval, i.e., Moreover, the whole system will tend to shed first where voltages drop the most. This location changes with the disturbance. Hence, the proposed scheme automatically adjusts the shedding location to the disturbance it faces. Note that the above features are achieved without resorting to a dedicated communication network. The controllers do not exchange information, but are rather informed of their respective actions through the power system itself. The drawback for this method for distribution network is that the tuning which consists of choosing the best values for Vth, C and K. A C and K combination suitable can be identified by minimising the total load shedding over all disturbance scenarios. Clearly this method would shed more loads for some scenarios. An additional concern is that the dynamic performance of the DG units and loads is not taken in account when performing load shedding if applied to the islanded distribution network and by trying to shed in steps the frequency drop in the network might drop significantly. automatic Intelligent Load Shedding Applications of intelligent load shedding in power system engineering (e.g. genetic algorithms, artificial neural networks, MonteCarlo etc.) have been demonstrated in [0] [0]. The characteristics which are inherent to intelligent methods, such as the ability to learn and generalization make it feasible for applications such as load shedding. You et al. in [0] discuss of a method that uses the rate of change of frequency to load shed. The method uses the same approach to calculate the required amount of load as in [0] and at the same time, the conventional load shedding method with undefrequency thresholds is incorporated to form a new two level load shedding method. The conventional load shedding method has longer time delays and lower frequency thresholds which can be used to prevent unnecessary load shedding in response to small disturbances. If the disturbance is large, the second layer will be activated and a block signal to the first layer is enabled. The second layer based on the rate of change of frequency load shedding will shed more load quickly at the early stage of the disturbance. Similarly as to paper [0], this method will have the same limitations when applied to the islanded distribution network. In the paper [0] which follows this study, the explanation of the selection of the settings for the relays is discussed. Agent technology is to try to assure that the method will withstand all possible disturbances. Traditionally after a major disturbance, the system is revisited and settings of devices and control actions are changed so that the system will withstand the same disturbance in the future. This however due to analysis of the system significant time and cost will be required. For the autonomous and adaptive learning capability for the agents, the reinforcement learning technique is used. Reinforcement learning is learning by interaction. The agent tries actions on its environment and then, the tendencies of taking particular actions are reinforced by receiving scalar evaluations of its actions. Thus determining the amount of load to be shed required to avoid collapse. The paper does not discuss whether the technique is applied online or offline through simulation. Clearly for the online this would not be ideal as it will take a lot of number of failures until the agents are properly set for that particular disturbance. For the offline simulation a concern is that for islanded distribution networks the topology, DG unit power and load demand will change thus making the decision of the action of the agents is difficult to train. Another concern is communication between agents. Fast communication would be required for coordinated decisions. Another approach to load shedding is the use of fuzzy expert system and is described in [0]. In this paper Sallam and Khafaga described a method to control the voltage instability by load shedding using fuzzy technique as fuzzy controller. The operation of the method relies on the experts knowledge which is expressed by language containing ambiguous or fuzzy description. The aim of this study is to design and analyse a fuzzy controller for the study to control against load and voltage instability by calculating the optimum load shedding as output. Similarly in [0] the authors propose genetic algorithms for the optimum selection of load shedding. These techniques search and optimise the amount of load shedding using objectives and constrains required for a practical load shedding method. Also in [0] the authors introduce another technique using the artificial neural networks is presented. To prepare the training data set for the artificial neural network, transient stability analysis of the power system is required and to find the minimum load shedding for various scenarios. By selecting the total power generation, total load demand and frequency decay rate as the input neurons for the method, the minimum of load shedding is determined to maintain the stability of the power system. In paper [0] Thalassinakis and Dialynas introduce a computational method using MonteCarlo simulation approach for the calculation of the settings of the underfrequency load shedding relays is discussed. The frequency performance as previously discussed in section 1.5 is used here as well. The strategy for the relay settings will be determined against amount of load to shed, time delay, rate of change of frequency and underfrequency level. A new strategy is developed by changing these settings. The MonteCarlo then computes the system through reliability indices of generating units, the system frequency and load shedding indices. load shedding based on static optimisation The first theory of applying load shedding using an on line dynamic simulation of the power system network was introduced by La Scala et al. [0]. Followed by an improvement of the method combing a control action to ensure angle and voltage stability enhancement in [0]. The first paper that introduced the same concept applied for large power systems to the smaller distribution network is described in [0] by Nelson and Aponte. A more recent study using similar technique is also presented in [0]. The paper presented in [0] describes the philosophy and the implementation of a preventive load shedding control algorithm for the application in dynamic security assessment. The methodology is based on nonlinear programming techniques, for assessing control actions to guarantee the dynamic security of power systems. The basic idea is that the online dynamic preventive control can be seen as a static optimisation problem with minimising function and equality and inequality constrains. The equality constrains consist in the discretisation at each time step of the differential algebraic set of equations representing the power system. The inequality constrains define a domain where the system trajectories should be contained in order to satisfy the requirements for the system performance stability and steady state voltage dips. In [0] the formulation includes corrective actions based on load shedding. The proposed method assumes that the analysis is performed to detect particular disturbances threatening the dynamic security of the system. The analysis is based suing the n-1 rule which is performed in advanced and applying the results immediately after the detected contingency. Each analysis has its associated strategies consisting with the corresponding amount of load to be shed at a fixed number of controlled nodes. The optimisation however is evaluated based on the steady state values of angle, voltage and active power (generator and load). Load shedding based on static optimisation performs load flow to calculate the initial P, V for all the nodes in the system. Then the method performs a transient simulation assessment to ensure the system is stable against angle and voltage. Followed by an approach to the minimisation of a function in presence of equality and inequality constrains consist in incorpora ting the inequalities in the cost function by adopting the penalty factor method and treating the whole problem as a minimisation in presence of the sole equality constrains by the use of Lagrange multipliers. This method has been used for synchronous generators in transmission systems. However in distribution networks because of the diversity of the generators and their ride through capability this approach could result in conditions where optimised solutions do not meet the requirements as shown in Figure 1 -2 [0]. Figure 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ2: Ride through capability of Generating Unit, DC Converter or Power Park Modules. Explanation of graph required. Each Generating Unit, DC Converter or Power Park Module shall remain transiently stable and connected to the system without tripping. However for small generating units connected in the distribution network their transient behaviour could be as shown in Figure 1 -2 b and c where local protection and circuit breaker operation of generators or sensitive equipment will be disconnected after such a response. Similar to the voltage is for the frequency range. Therefore the load flow with corrective control for angle and voltage stability approach for the load shedding optimisation is not appropriate for distribution networks. In [0] and [0] describe of a method implemented in distribution networks where not only the amount of load shedding is optimised but also the time for the disconnection. The current trend is to apply the corrective measures as soon as possible or delayed for the sake of event discrimination. The study and results however show that when the corrective action is applied at the optimal time increased damping and enhanced response are observed. summary The use of load shedding as a tool to keep the network stable has been constantly evolving, and different approaches have been formulated. Relaying schemes like underfrequency and ROCOF [0] [0] are some examples of the mechanisms implemented to trigger a load shedding event. Typical load shedding schemes based on predefined threshold set points is quick, simple and reliable measure against system disturbance. When the frequency of the system reaches a specified threshold value, a time delay is inserted prior to the shedding action in order to avoid overshedding and assist the coordination of the next stage of load shedding action. This technique however when adopted for the islanded operation of small distribution networks would have several disadvantages. Too few frequency levels could lead to overshedding, but on the other hand, time delays between stages could add up and may not allow for enough load to be shed in time to re-establish nominal frequency. The implementation of ROCOF techniques mitigates some of these problems. The ROCOF value calculation is an immediate indicator of the power imbalance; but for the distribution network the variation of the DG units operation would make this measurement unreliable. Also the average ROCOF calculation may take too long and eventually make the load shedding method slow in operation. Even if accurate measure of the islanded distribution network ROCOF valu

Trends in Broadcasting

Trends in Broadcasting Television broadcasting industry in India ia a very huge industry and has thousands of programs in almost all states of India. Almost half of the households in India own a television. In a research conducted in 2010, it was found that a total of 515 channels are available in the country out if which nearly 150 are paid channels. Indian television markets display today many of the attributes of the sector typical to broadcasting across the world, a mix of state-supported and advertising based services; a separate and growing segment offering scrambled services in return for subscription; a variety of distribution means. At the same time, Indian television has a number of unique characteristics that are the result of its size and history, source of funding, regulation and technology choices. In common with other Indian industries, the development of broadcasting has been coloured by Indias comparative isolation due to tariff barriers and other regulatory constraints. These impacted unevenly across television and related sectors, while Bollywood flourished in part because of the scarcity of non Indian content, Indian broadcasting was confined to a single service Doordarshan offered over some of the national territory. Without competition, Doordarshan could focus from the 1960s to the late 1980s on programmi ng that responded to the states development goals and secular messaging but ultimately proved to be unappealing to audiences. CURRENT SCENARIO. In India, the television broadcasting industry going through remarkable changes and it has now become one of the fastest growing sectors of the country. The main reasons for this are rising per capita/ national income, increase in the growth of economy and powerful macro-economic fundamentals, democratic set up, good governance as well as law and order position in the country. The Indian broadcasting industry plays a vital role in creating peoples awareness about state laws and policies and programs by providing education and information, besides creating healthy business environment within the country. Thus, it helps the people to be the active partner in the nation-building venture. At the present stage, in Indian television broadcasting industry there are almos110 million TV users in India, out of which almost 70 million are cable and satellite homes and rest 40 million are served by the public broadcaster. TRENDS IN INDIAN BROADCASTING INDUSTRY. Indian Broadcasters are now under increasing pressure to present superior quality content, as is reflected in some recent trends: Narrowcasting or launch of specialty or niche channels, which achieve faster breakeven (given the lower investment) focus also being brought onto regionalization and content creation for Tier II and Tier III towns. Launch of reality shows, despite the high investments required, to gain viewership; broadcasters are depending on reality shows for channel branding. Near immediate launch of movies on the broadcasting platform following theatrical release, although at high acquisition costs; however revenue potential of such broadcasting remains a challenge for the broadcasters despite the relatively high gross rating points (GRPs) of the programmes. Switchback to the outright exclusive rights model for movies to reduce fragmentation of viewership, albeit at higher costs. Increasing presence in the overseas markets so as to tap non-resident Indians (NRIs) who have been demanding Indian content; this along with dedicated local programming is opening up an additional revenue stream for Indian broadcasters. Overall, competition is expected to keep profitability under strain for most broadcasters, especially those in the GEC space(GEC refers to fiction and non-fiction shows; examples include, among others, Colors, Zee TV, Sony, Star Plus, and Imagine), over the near to medium term. ENVIORNMENTAL ISSUES. The television industry in India continues to undergo solid competition from the digital cable and satellite TV industries. The cable TV industry, in special, represents a bigger threat to future industry growth. A number of elements points to low development in advertising revenue, including forecast low economical growth, the declining total share of the TV audience, and competition from new media. The dim outlook for this industry has already prompted News Corp to expand its satellite TV interests. The onset of digital television may provide a much needed boost for demand. PORTERS FIVE FORCES ANALYSIS OF INDIAN BROADCASTING INDUSTRY. Bargaining power of Buyers. Strength of Force-High The bargaining power of customers determines that how much customer can impose pressure on the margins and volume of a industry. Viewers experience frequently change, providing little faithfulness to any particular network. Advertising buyers dictate television programming choices. The suppliers customers are bitty, so their bargaining power is low. The cost of switching from one supplier to another supplier is very high.. Bargaining Power of Suppliers . Strength of Force Low- Medium Since most suppliers to Broadcasters have either been acquired/ have a tie-up with the broadcasters, the bargaining power of suppliers is low. For ex- Viacom has acquired Paramount. However, Independent content providers pose a major challenge to online revenue model for broadcasters. The suppliers comprise a large number of small operators. The service is undifferentiated and can be replaces by substitutes. The customer has awareness about the production costs of the products. Threat of New Entrants. Strength of Force-Low If the competition with in an is higher then it is easier for other companies to enter this industry. In Indian television broadcast industry, new entrants could change major determinants of the market environment (e.g. price, market share and loyalty) at any time. There is always a hidden pressure for reaction and alteration for existing players in this industry. The threat of new entries will depend on the extent to which there are blockades to entry. These are typically High start-up capital is a big de motivator. It is difficult to access the distribution channels for new entrants. New entrant has a number of problems finding skilled employees, materials, and suppliers. Serviceable used equipment is expensive. Long-lasting economies of learning and scale also de motivate the potential new entrant. Economies of scale (minimum size requirements for profitable operations). Limited important resources, (e.g. qualified expert staff). Raw materials are controlled by existing players. Threat of substitutes. Strength of Force-Medium A threat from substitutes exists whenever there are alternate products with lower prices of better functioning parameters for the same purpose. They could possibly attract an important proportion of market volume and therefore reduce the potential sales volume for existing players. This category also associates to complementary products. Similarly to the threat of new entrants, the substitutes determined by factors like. The relative price for performance of substitutes. Current trends. Customers have to incur switching costs. Also, adequate substitutes are available. Possibly, One Broadcasting medium substitute for the other(movies as a replacement For TV) Pirated content is a decent(and free substitute). Other free time activities could be substitutes (concerts, games, gambling, gardening, sports, restaurants. COMPETITION IN INDIAN BROADCASTING INDUSTRY. As broadcasting is one of the main industry of any country, so like all other industries there is strong competition in Indian broadcasting industry. The entry of newer players in the Indian broadcasting industry has had the positive impact on expanding the overall market. For instance, since the launch of the new channels like GECs 9X, Colors, Imagine and Real, the overall GRPs have increased by around 30 per cent in less than a year, according to industry estimates. This has also helped in expanding the overall advertising volumes by 31% in 2009 over 2008. However, with the number of channels increasing significantly over the past decade (over 460 in 2009 from 120 in 2003), every broadcaster is struggling to retain its share of the advertising pie. Following the fragmentation of the advertising revenues, the viewership ratings and hence the placement of a channel have become even more important for broadcasters. In the highly cluttered GEC genre, the largest in the Indian broadcasting space, it has become critical for broadcasters to invest heavily in content development and acquisition so that they can differentiate themselves from their peers. In addition, GECs in particular, being highly dependent on mass segment viewership to attract advertisers, are being forced to incur large carriage fees for the placement of the channels on the prime band in view of the lower bandwidth availability on the analog distribution network. This high expenditure is slowing down the process of achieving breakeven for channels considerably. To leverage the benefits arising out of foray into regional markets, in general, the basic strategy followed by new entrants in regional markets is to first establish their presence through a GEC, a news channel and a movie channel, and then get into more niche categories. However, as regional markets begin to saturate, a closer evaluation of the regional markets potential would have to be done before launching a new regional channel. MARKET SHARE: Market share in Indian economy the service sector was drastically increased up to 2007 after words it decreased to 5.5% because of IT fall in India. In service sector the portion of media broadcasting was slowly increased in the year 2008 due to the floods and elections the media broadcasting industry was increased. The swift growth and change in the television broadcasting sector is composed of several essential characteristics: the emergence of mega global communication companies as a result of merger and acquisitions; privatization of existing broadcasting companies; the relaxation of foreign ownership restrictions; corporate investment in newer media such as cable and satellite television; and transnationliztion of advertising and its convergence with communication empires to create a demand for and to promote cultural products and other industries such as consumer goods and services GROWTH. The Indian television broadcasting industry consists of television distribution, advertising content and other services has reported a compounded annual growth rate(CAGR) of 13.8% over the period of 2005 to 2009 increasing to Rs 26,550 crores according to industry estimates.the industry continues to remain at an attractive mode of entertainment because of its reach and penetration. SWOT ANALYSIS. Weaknesses. Domination of 4-5 major players is a negative sign thus creating somewhat monopolized industry. Ongoing weakness of U.S. automakers will have an impact on advertising spending. Environmental issues. Full depending on power supply. Remote area can not be accessed Threats. Slowing Real GDP, inflation, and jobs concerns. Unstable outlook of the industry. Oil prices are beginning to rise, which will cause a decrease in available Challenges of Broadcast Industry and Opportunities for IT Solution Providers cash for consumers to spend. This is seen as advertisers insist that rates be based only on live viewing and not time shifted viewing. Threat of consumer shift towards alternatives. Strengths.
