Successful strategies for small music venues
Successful strategies for small music venues This study will analyse what successful marketing strategies for small music venues are. The topic is of special interest due to different factors. According to different surveys among them the Mintel Live Entertainment and Music Concert study, there is a growing interest in live music acts (Music Week, 20.10.2007). People are increasingly interested to catch a band rather than going to a club or watching a comedy acts, so says Keith Ames, member of the Musicians Union (Music Week 17, 25.07.09). On the other hand, one can read more often about the closure of smaller live music venues, venues that can host around 200 people. A number of venues were forced to close down, among them The Point in Cardiff and The Charlotte in Leicester. These venues have hosted big named artists. The venues, especially Leicesters legendary Charlotte, were symbolic for their traditional public house environment. Many promoters are complaining that festivals, stadiums and arenas are dominating the market and drawing the money away from the smaller gigs and tours. That might be in favour for the bands itself but smaller operating venues are not in favour of that concept. The promoter Rupert Dell mentions to Music Week, that it is almost impossible to make money if venues are operating under a capacity below the 300-500 mark, though, there are places that do well, mostly be relying on the bar. It is up to the small live music venues to find a way to successfully compete against the bigger venues. They have to basically think outside the box to attract people on the venues. Many venues around the UK have become very successful in viral marketing, also knows as word-of-mouth, and targeting the right fan base. Social networking became an essential part of the venues marketing approaches. Mintels research also indicates that social networking sites and downloading have promoted, rather than damaged, the live music industry, with the result that regular internet users are more likely to go to gigs. Though, Dell believes that social networking sites can hinder as well as help and says venues have to be prepared to work harder than ever to attract the crowds. Many local venues around the UK still follow their concept that they have been there for ages and doing a good job. There venues include The Ruby Lounge and Night Day in Manchester, Sheffields Leadmill or the Brudenell Social Club in Leeds, on which the focus will rely on in this study. There are many more factors that make it difficult for smaller music venues to compete against the bigger ones. One of them used is the Licensing Act 2003: An Act to make provision about the regulation of the sale and supply of alcohol, the provision of entertainment and the provision of late night refreshment, about offences relating to alcohol and for connected purposes. (Legislation.gov.uk) The license requirements cost too much money for the venues. The benefits for the venues itself are too little. Though, it has put into question of the Licensing Act 2003 really harms or encourages the small live music venues. The Licensing Act 2003 has been changed in favour for the small venues (FAQ Licensing Act 2003). Since small venues were still struggling so much, the Parliamentary Select Committee allows certain premises to operate without an entertainment licence. The so-called Two-in-a-bar rule, allows venues that host a capacity up to 200 people can operate without an entertainment license when only one or even two artists are performing in the venue (The Independent, 16.02.2000). There have been many approached to expand that rule since the venues are still struggling. That is only one factor the venues have to deal with. Therefore it is the venues task to find a way to stay competitive and solvent. In order to do so, the venues have to find a successful marketing strategy. To evaluate that, different study aims and objectives have arise which will be exemplified in the following excerpt. Study aims The aim of this study is to investigate what marketing strategies are adopted by small and private owned live music venues in order to compete against the bigger ones. In order to achieve this aim the following objectives were devised. Study objectives The objectives of this study are as followed: understand how live music entertainment is successfully marketed understand the marketing approaches that are available for implementation and taken by managers of live music venues understand the problems faced by the organisations marketing a service like that investigate how small music venues market themselves using the Leeds area for a study case. 1.4 Choice of topic This paper is an investigation in the marketing approaches of live indoor music venues and which strategies are most appropriate for promoting the venue and the staging event. As mentioned above, there has been an immense increase in the live music during the recent years. But even though that is the case, many live music venues are forced to close down. That effects especially smaller venues. Besides of frequent concert visits, the author is genuinely interested in the marketing action provided by those venues in the events industry. And after reading an article about the struggle of small live music venues, it was of great personal interest to see what can be done to compete against the wide range of live music venues. Chapter 2 2. Music performances in the event context In attempting to explain music performances in the events nature, the author finds that music events are classed as fairs and festivals (Goldblatt, 1997) and art festivals/events (Getz, 1997). These events need a lot of support and technical back up and therefore have the potential bring the spectators and performers together. According to this statement Goldblatt (1997, p7) also quotes: Fairs and festivals provide unlimited opportunities for organisations to celebrate their culture while providing deep meaning for those who participate and attend. Gretz on the other hand describes entertainment events as followed: Art festivals are universal, but with considerable diversity on form and type of art featured Gretz (1997) sees it as essential put art festivals in three different categories: Visual (e.g. handicraft, sculpture, painting) Performing (e.g. music, dance, drama, cinema, poetry; usually involving performers in from of the audience) Participation (no separation of audience and performer) In the context of this study, one can say that live music performances can be categorised under art and festival events, more precisely they can be defined as performing arts. After having music events categorised, the next chapter will deal with the wide field of marketing and marketing of small music venues. Chapter 3: Marketing 3.1 Introduction In order to satisfy the study objectives one and two of this dissertation, the author will explain the terms of the marketing concepts and explains as well as marketing strategies which can also be implemented in businesses such as music venues. 3.2. What is Marketing? Marketing is an essential and indispensable part for all sorts of businesses, including the events industry. The complexity of marketing is also seen in the wide range of literature that exists. Marketing is an always changing topic. Definitions are steadily renewed and expanded. Dibb, Simkin, Pride and Ferrell (2006) are defining marketing as followed: Marketing consists of individual and organisational activities that facilitate and expedite satisfying exchange relationships on a dynamic environment through the creation, distribution, promotion and pricing of good, services and ideas. Kotler (1997) states: Marketing is a social and managerial process by which individuals and groups obtain what they need and want through creating, offering, and exchanging products of value with offers. Blythe (1998) declares: Marketing is the management process which identifies, anticipates and satisfies customer requirements efficiently and profitably. The author finds these definitions mentioned above appealing because it succeeds in addressing the importance of management and profit in relation to marketing, and the modern day of business. As one can tell from the definitions above, the focus of marketing is on satisfying human needs in return of benefits for the business. A business need to satisfy their customers in order to succeed. That is the major concept of marketing. When the customers a kept happy, they will return to the business to provide additional custom. For the business itself, marketing should provide a financial benefit and a greater understanding of the organisation. Therefore it is extremely important for marketers to understand their markets customer, competitors and market trends and also the businesss capabilities. Understanding general market trends is also very relevant for a business. That includes all those that include the market environment: social trends, technological enhancements, economic patterns, changes in the legal and regulatory arena, political influences (Dibb, Simkin, Pride and Ferrell, 2006). The product or service offered must be in line with the customer needs and also the service level must clearly be determined. Furthermore pricing and payment issues must be decided, channels of distribution establishes in order to make the product or service available and the promotional strategies need to be devised and executed to communicate with the targeted customers. Is that the case, marketers can develop their marketing strategies and programmes. According to Dibb et al. (2006) marketing consists of the ASP approach: Analyses first, then Strategy decisions with, finally, the formulation of marketing Programmes. This approach consists of basics like satisfying customers and stakeholders, target the right customer group, facilitating exchange relationships, staying ahead in a dynamic environment, increasing the market share and one of the most important facts enhancing the profitability or income. For marketing live entertainment events, marketers use a slightly different kind of marketing which is classified as service marketing. This will be explained in the following chapter. 3.4 Service Marketing 3.4.1 Introduction Relating to study objective number one which covers the questions how music entertainment is successfully marketed, the author sees it as inevitable to give an understanding of service marketing. Service marketing is the most appropriate kind of marketing in the context of entertainment. The author sees it for necessary to define first what exactly is meant by the word service and characteristics service has. Berry (1990) defines service as followed and at the same time shows the distinction to the word good: In general, good can be defined as objects, devises, or things, whereas service can be defined as deeds, efforts, or performances. Hoffman et al. (2006) lists four main characteristics for services: intangibility, inseparability, heterogeneity and perishability. Due to the importance of these terms, they will be briefly explained in the following sub-chapters. 3.4.2 Intangibility Hoffman et al. (2006) defines intangibility as followed: A distinguishing characteristic of services that makes them unable to be touched or sensed in the same manner as physical goods. An example of intangibility could be a concert to be enjoyed at a music venue. The customer purchases a concert ticket, which entitles the customer to an experience. Since the concert experience is intangible, it is subjectively evaluated; that is, customer of services must rely on the judgements of others who have previously experienced the service for pre-purchase information. The customer will return with the experience of the concert and his memories, the physical ownership that he retains is only the ticket stub. An importing part of a service marketing programme involves to reduce the customers perceived risk by adding physical evidence and the development of strong brands. 3.4.3 Inseparability Hoffman et al. (2006) offers following definition: A distinguishing characteristic of services that reflects the interconnection among the service provider, the customer involved in receiving the service, and other customers sharing the service experience. An example for inseparability could be a musical performance that is created (produced) as it is experienced (consumed) by the audience. The interaction between customer and service provider defines a critical incident. Critical incidents represent the greatest opportunity for both gains and losses in regard to customer satisfaction and retention. 3.4.4. Heterogeneity A distinguishing characteristic of services that reflects the variation on consistency from one service transaction to the next. (Hoffmann et al, 2006) Heterogeneity makes it impossible for a service operation to achieve perfect quality on an ongoing basis. Many errors in service operations are one-time events. Another challenge that heterogeneity defines is that the consistency can vary from firm to firm, it also varies when interacting with the same service provider on a daily basis. 3.4.5 Perishability A distinguishing characteristic of services in that they cannot be saved, their unused capacity cannot be reserved and they cannot be inventoried. (Hoffmann et al, 2006) The customer is usually involved in the production process of a service at the same time as it is produced. Therefore it can be difficult to control and monitor and ensure stable standards. It is not possible with services to pre-deliver an inspection that is open to manufacturers of goods. These explanations provide a brief overview about the characteristics of services which include music performances. Following it will be explained how a service like that can be marketed and brought to the target customer. 3.5 Communication in Service Marketing Introduction With the focus on the second study objective where is was questioned which marketing approached are available, there will be an investigation of the field of service marketing. Marketing within events is based on communication. This can be done by directly informing the customer of a service that is offered, though customer feedback or market research. The main role of a communication strategy is to inform or remind a customer about a service that is offered. The organisation has to create customer awareness and also position an offered service in the customers evoked set of alternatives. Keeping the customer updated with the services is an essential part of the communication service, since people forget quickly and easily (Bateson, 1992). There are two ways in which communication of services may be handled: non-personal sources and personal sources. Non-personal sources are mediums such as television advertising or printed information in newspapers or magazines. Personal sources are on face-to-face basis. It is though all individuals who are in contact with the consumer of purchase, consumption and postpurchase stages. The objectives and strategies of communications can differ, depending on the nature of the target group (Hoffmann et all., 2009). Therefore communication strategies and objectives will be closer described in the following sections. 3.5.1 Communication Strategy in service marketing The development of a service marketing strategy has similarities to the regular marketing strategy which includes the identification of the target market, selection of a positioning strategy and tailoring a communication mix to the targeted audience that reinforces the desired positioning strategy. The three objectives of a communication strategy in general are to inform, to persuade and to remind. It is possible that these objectives can change over the course of the products life circle, depending whether the organisation would like to target current users or nonusers (Hoffman et all., 2009). 3.5.2. Determining a target market In order to meet the general communication objectives, the service organisation must analyse the need of consumers and then categorise consumers with similar needs into market segment (Masterman and Wood, 2006). The segmentation can be applied on a very simple level. A differentiation can simply be implemented by categories such as consumer/organisational markets or male/female segment or local/national/international market. Often segmentation can be a little more sophisticated by using lifestyle, attitudes or opinions and interest. An example of a music event is be a concert production. Of interest here for determining the target group is firstly the music taste of the targeted audience, lifestyle and also reference groups. Age, gender or economic situation are less relevant here (Cottle and Ratneshwar, 2003). Once the target audience has been evaluated, objectives can be developed for each identified target group, as each group may have different communication preferences. 3.5.3. Organisations positioning strategy After having selected the target group, it is necessary to establish a positioning strategy. A positioning strategy is a plan for differentiating the organisation from its competitors in consumers eyes (Hoffman et all, 2009). But there is also the competitive position, which determines the position among the competitive environment. Positioning involves a strategic manipulation of the organisations marketing mix variables: product, price, promotion, place, physical evidence, people and processes. Every single of the components is controllable. When these are effectively combined, the organisation can balance the factors that are uncontrollable and which exist in every organisations environment like technological advances, customer needs, new and existing competitors, government regulations, economic conditions and the effects or seasonability. Kotler (1997) states that companies that fail to alter their positioning strategy to reflect environmental changes in order to differentiate themselves from competitors often falter in the long term. 3.5.4. Competitive position When identifying the current position, the process uses market share trends to determine whether the organisation is a market leader, market challenger, market follower or market nicher. A market leader will have different strategic options to an organisation on a niche market or a smaller player in the field. In relation to the study objectives one and two, the authors finds it relevant to explain the characteristics of a market nicher since small music venues feature characteristics of a market nicher. Often market nicher tend to be very successful with their strategy by avoiding direct conflicts with the larger competitors. In order to achieve this success, the organisation created a kind of specialism in a particular area. This can be the a product itself, the service level or the market that they operate in. The professional competence protects them from attacks and provides enough space for growth of the right target market was selected. Growth in this context does not necessarily mean market expansion but more through market penetration (Hoffman et al, 2009). 3.5.5 Positioning According to Ries and Trout (1992), positioning refers to the position that a product has in the consumers mind in comparison to the competing product. It is important to determined the desired position for each target market. The marketing mix can change according to the target market since the focus has to be changed according the preferences of the target audience. For changing the existing position of a product or brand, marketing communications are often used. By repositioning, the organisation has the chance to gain market share, attract a new market, or recondition an offered product that is coming to the end of their life cycle. Marketing communication helps to change existing approached of a service by using new information, imagery and comparisons. When positioning, it is necessary to have a good understanding of the current position. In order to see how a product is perceived when comparing it with the competitors, it requires a good market research in each target market. Depending on the organisation, there are several criteria on which a product is evaluated. For a concert venue, the ease of access, atmosphere or performance may be of major interest. It is important to identify which is the most relevant criteria for each target group. When having evaluated that, positioning can be made a lot easier, also by using different tool like a positioning map. These maps are very useful for evaluating the competitors offerings and also to advise future strategic actions (Masterman and Wood, 2006). Positioning is an essential aspect of a marketing plan and often leads to a so called positioning statement. These positioning statements shows how an organisation wishes to perceive their products and brand and created consistency, clarity and continuity in how it addresses to target market (Kanzler, 2003; Davidson and Rogers, 2006). 3.6 Communication Mix Introduction In an attempt to satisfy study objective one and two of this dissertation, the author within this chapter explains the concept of the communication mix, also known as promotional mix, and as well explains what tools are available to marketing personnel to marketing a service like live music performances. 3.6.1 What is the communication mix? The communication mix is a set of communication tools which marketers use to communication with their target market. The major tools that are used are media advertising, public relations, sales promotion and the personal selling. This promotion mix has been extended to word-of-mouth, corporate identity, sponsorship and corporate hospitality, e-marketing, exhibitions and events and merchandising (Masterman and Wood, 2006). Wigram (2004) states, when utilising these different methods, the organisation can deliver experiences and information which are relevant to the different target audiences and which collectively deliver the brand vision. When staying in subsequent contact with the customer, it is also important to consider the communication budget (Boone and Kurtz, 1993). Especially for small firm that is very important due to the limited budget that is available. When the budget has been determined, the target audience, objectives and budgets are divided among the different areas of the communication mix. Following there will be different communication tools explained that are relevant and most appropriate for small businesses such as live music venues. Public Relations Due to the complexity of PR, the topic be briefly explained and explained why PR is appropriate for small organisations including music venues. In the following sub-chapter, there will be an explanation of PR as well as how it is relevant to an organisation like a music venue. What is PR? Public relations is a wide field and there a different definitions for this term. Palmer (2008) states that PR is the deliberate, planned and sustained effort to establish and maintain mutual understanding between an organisation and its public. Masterman and Wood (2006) write that PR is used to raise the success of an organisation. It covers a corporate, financial, marketing, community and internal activity. As mentioned before, PR aims to change the opinions of the parties that have a certain influence on the success of an event. PR should also focus on credibility and reputation and therefore with the external perception. Yeshin (1998), Pickton and Broderick (2001) and Fill (2002) agree that PR has a very wide role, not only to support the marketing act. It engages managing communications with every group of the organisation that are considered an important factor in the successful implementation of an event. Uses of public relations Following there are listed a few ways of how to use PR. They are adopted by Masterman and Wood (2006, p88) and can be categorised as follows: Customer retention: using PR activity such as events, launches and media liaison to support marketing push to retain customer, grow sales and market share. Investment: using PR activities such as corporate hospitality to encourage new and further investment via the development of investor relations. Bargaining status: using PR to build brand in order to achieve better relationships with supplier and customers Staff relations: using PR to portray a healthy organisation in order to attract and maintain a desired quality of staff. Business development: initiating and building new business through PR activity such as events, corporate hospitality and business-to-business communication on order to develop business from new or existing customers. The author believes that these categories describe very well, how PR can be engaged in a business and what benefits it can bring for the organisation. Media advertising Introduction Advertising is a very suitable tool for reaching various target groups. Individuals are subjected to at least 600 advertisements a day (Clow and Baack, 2004). Mostsly the crucial factor for the choice of media are the costs. Due to a wide range of tools, even small firms can advertise events very favourable. Advertisements are designed to transfer an event message to the customer, inform, persuade and remind him (Boone and Kurtz, 2002). The advantage of media advertising is that one can reach a mass audience, also on a selective basis (Pickton and Broderick, 2001). Shimp (1997) confirms that advertising is a crucial factor for the successful introduction of a brand or event. Greetz (1997) adds that advertising increases the awareness of an events and that it can demand in sales. Following there will be a brief explanation of a few tools that are very suitable for organisations of all kind. Television Television targets a very wide group of people, often on a national level; very suitable for big events like e.g. World-wide sport events. A disadvantage is the cost of production which can be relatively high and therefore not affordable for small businesses. Newspaper Newspapers have a few advantages. One of them is the credibility and also that it offers a great targeted flexibility, from regional and local editions. Boone and Kurtz (2002) also state that local newspaper have a great impact on the local community, since they can be more easily involved. Furthermore, with newspapers, they have the advantage of being relatively inexpensive, especially local papers. Magazines When advertising in consumer magazines, it has the advantage that they are highly segmented. They offer a sophisticated targeting opportunity. Though, promoters often have to plan a long time ahead. During that time, the event plan could might have changed. Cost-wise, it depends on the magazine, whether it is a small more local magazine or a national one. Radio Radio is a very effective mass medium for creating a one-to-one relationship with the customer. It has a great flexibility in advertising locally, regionally or nationally (Clow and Blaack, 2004). As Masterman and Wood (2006) put it: The beauty of local radio for event organisers is its place in the community. Using local radio, can also be relatively inexpensive and target the local listeners. Outdoor Outdoor includes traditionally posters, billboards, transportation and street furniture. This kind of advertising is very low in costs, has a broad reach and long life. Also fly-posting is a very popular medium and often used for music and club promoters (Masterman and Wood, 2006). E-marketing The internet is another mass medium that is nowadays widely used. This mass advertising and e-mail is a cheap ways for direct marketing. Many venues have their own websites which can add longevity to an events. It is a good opportunity for very creative and innovative event marketing strategy. The websites should be updated regularly with information that are of interest to the various target groups. 3.7. Problems arising with the service communication mix Introduction With the focus on the third study aim which focuses on the problems that are faced by the organisations marketing services like live music performances, there will be an investigation on problems that arise within the communication mix. According to Hoffman et al (2009), inseparability and intangibility offer special challenges that have to be followed when implementing and developing a communication strategy. There are different problems that can appear, e.g. mistargeted communication, the management of the consumers expectation, internal marketing communication and selling/operating conflicts (George and Berry, 1981). These problems will now be further explained. 3.7.1. Mistargeted communication Positioning is very important in marketing. It can improve the organisations marketing efficiency when targeting different marketing activities according to the different target group who behave differently towards the organisation. The consequences of mistargeted communication for certain service organisations are clearly more significant than for traditional goods-producing organisations because of the shared consumption experience. Mistargeted communications are communication methods that affect an inappropriate segment of the market. 3.7.2. Managing Expectations Another problem are the customers expectations. An organisations communications are often interpreted as an explicit service promise that consumers use to base their initial expectations. The organisation has the opportunity to direct control the sources of expectation. Though, the organisation cannot influence past experiences and competitors activities. By having that control, the organisation has to define the objectives for the communication mix. One strategy for an organisation including a music venue, would be to reduce consumer expectations as much as possible. That would result in a higher satisfaction level of the customer. On the other hand, in competitive terms, many organisations build up expectations in order to differentiate themselves in the market place and try to attract people to them and not to the competitors. However, there is a risk, that organisations promise too much and increase the customers expectation to an unrealistic level. It would be most effective to match the expectations of the customer to the performance characteristics of the service delivery system (Bateson, 1992). 3.7.3. Internal marketing communications So far, it marketing communications were only mentioned to the external environment. But also internally, marketing communication is extremely important since it can be highly motivated if empathised by the staff. The staff has to have a clear understanding of the communication methods within the organisation. It might raise the

How Attitude Shapes Our Life Essay
We have very often heard people saying that Attitude is how one shapes his or her life. Now what exactly is Attitude? Attitude is basically how one assesses on factors like people, objects, issues or events. They could either be positive or negative, that depends on how one views the situation. Based on researches, it has been understood that there are several components that makes up a persons attitude. The components could be like for example, an emotional component where based on your emotions is how a situation or person is being valued. Another component is the cognitive component where in it is based n your thoughts and believes of the subject. And the last component is the behavioral component and this is one important component as it influences our behaviour. Attitudes that influence or behaviors could also include the explicit and implicit. Explicit attitude are those that e are constantly aware and influence our thoughts and believes. The Implicit attitude is something that is unconscious, but it could also influence your behavior. Attitudes get formed from experience. They are formed over the years either from observation or from experience. They can be learned in a variety of ways. Even a simple dvertisement could influence you and may even have a change on your thoughts about a particular product. This kind of attitude formation is known as classical conditioning. Another kind of conditioning is the Operant Conditioning where the attitude develops from other peopleââ¬â¢s thinking. Sometimes people around us could make an impact on our behavior and change ourselves. And finally attitudes could be developed by observing people around us. A simple example of this kind of attitude development is, kids trying to be what their parents are. This is just observation and imitation, that develops into an ttitude later. Attitude does influence ones behavior. Studies have shown that people behave according to their attitude under certain conditions. Condition like when expecting a favorable outcome, due to personal experience are some of the examples. Attitudes could be changed. Attitudes do impact our behavior, but they are not imposed on stone within us. They could be changed for betterment. Attitudes could be changed in two ways. Either they get motivated or they get influenced. In both the ways they do think about the messages that they have observed and this could mark a difference in their way of hinking. Scenarios in life could be made good or worse, based on ones attitude to the situation. Even if you are in a very bad situation, and you hold a positive attitude, you may come out, however even if you are in a moderate situation and you hold a negative attitude, you could worsen the situation and create discomfort not only for you, but for people around you. In short, Attitude is like magnet. Possessing good Attitude attracts all positives in your life and Bad Attitude attracts all negatives in your life. It is you who decides what you want and could change accordingly. After all, attitude Matters!

Biopsychosocial Perspective Essay
Psychologists past, present, and future desire the answer to one basic question; ââ¬Å"what factors influence a personââ¬â¢s physical and mental health are they related if a relationship existsâ⬠; thus Health Psychology emerged. In pursuit of the answer several models or perspectives came about. Over time psychologist realized that focusing on one causal factor results in partial information for analysis of health and illness. Thus, the biopsychosocial model became the primary perspective used and is the focus of this paper. ââ¬Å"This perspective recognizes that biological, psychological, and sociocultural forces act together to determine an individualââ¬â¢s health and vulnerability to disease; that is, health and disease must be explained in terms of multiple contextsâ⬠(Straub, 2012, p. 16). Achieving an understanding of biopsychosocial perspective requires a description of the systems and three contexts of this theory, examination of the influence of this theory on the biomedical viewpoint, and examination of how the interaction of biological, psychological, and social factors influence a personââ¬â¢s health. Through a hypothetical scenario an illustration of the ways in which all three factors interacts and influences an individualââ¬â¢s health and well-being will emerge to reaffirm understanding. Three systems and contexts The biopsychosocial model consists of systems and three contexts: immune system, endocrine system, nervous system, and cardiovascular system, as well as biological context, psychological context, and social context. As most humans know the immune system is how people fight off disease and illness. If the immune system is weak then the disease or illness will take over and weaken its host. The endocrine system is the glands within the body and the hormones produced by the glands. The nervous system controls the glandsà through stimulation. The hormones released from the glands interact throughout the body to maintain homeostasis. The nervous system comprises the brain, the sensory organs, the spinal cord, and all the nerves connecting these organs with the rest of the body. The primary job of the nervous system is controlling the body and communication within its parts. The cardiovascular system is the blood, blood vessels, and the heart. The primary job of the cardiovascular system is to carry oxygen, nutrient, cellular waste products, and hormones within the body. All these systems work together to keep the body functioning and healthy. If any system is weak for any reason the body is vulnerable to disease and illness. The systems work together within the human body, but they also interact with the biological context, psychological context, and social context to influence health and well-being (Albery & Munafo, 2008). The biological context examines how genetics influence health. The psychological context examines how psychological influences (coping strategies) affect health and illness. The social context examines how social influences (culture, family, societyâ⬠¦.) affect health and illness. These systems and contexts work together like the gears of a clock to influence an individualââ¬â¢s health and well-being. If a gear gets nicked the clock starts to slowly lose time, but repair the gear and the clock is good as new. This is true of the biopsychosocial model of health and well-being also. The biopsychosocial model was not the first model psychologist used to explain health and well-being it was the biom edical model. Influence on Biomedical Model The biomedical model considers the absence of disease is physical wellness. This model is good practice but it has limitations. The biomedical model focuses on health and well-being as biological issues with biomedical solutions (Sutton, Baum, & Johnston, 2005). On the other hand, the biopsychosocial model takes into account the whole person leading to extensive research in many aspects of wellness. It addresses more than physical well-being as many people now are ill but they have no presence of disease. Socioeconomic status, race, ethnicity and generational differences all play important roles in this model of wellness (Marks, Murray, Evans, & Estacio, 2011). The biopsychosocial model is an expansion of the biomedical model. This new model agrees that biological issues influences health andà well-being, but also believes that psychological and social issues influence health and well-being as well. Three factors influence on health and well-being A 30 year old mother of four children under 10 goes to her physician complaining of extreme fatigue and a loss of energy. Many people would say ââ¬Å"of course you are tired. You have four young childrenâ⬠. She has high blood pressure, but her medication controls it so that is ruled out as the cause of her fatigue. Her doctor runs blood work, sends her for a sleep study, and asks questions about social and psychological issues that could be bothering her. When all the results are in there is no answer for her fatigue so the doctor diagnosis her with Chronic Fatigue Syndrome which means that no one knows why you are tired. Over the next several years she is in and out of her doctorââ¬â¢s office. The fatigue has such a toll on the woman that she gets sick easily and more often. Until she turned 30 this woman only had seasonal allergies and never got the flu or a cold. Now she seems to be sick more than not. Using the biopsychosocial model to examine this womanââ¬â¢s health and well-being will show how the biological, psychological, and social contexts as well as the systems are interacting to influence her health. When the doctor was questioning the woman about her psychological and social well-being he was ruling out depression as the cause. The woman is not fatigued because she is a busy mom rather the cause is a deficiency of a chemical in the brain. Through the numerous visits to her doctor she learns of a vitamin D deficiency, an underactive thyroid, and finally the root cause of her fatigue; Narcolepsy. Narcolepsy is a sleep disorder which affects an individualââ¬â¢s waking hours as a result of insufficient sleep. This disorder leaves the woman needing to take medication to sleep and medication to stay awake, but still feeling fatigued about half the time. The systems involved in this individualââ¬â¢s health issues are the nervous, endocrine, and cardiovascular. Looking back at the clock analogy, three of the gears of her clock have nicks. Since three of her systems are weak this woman is vulnerable to disease and illness. The biological context of her health is the deficiency of t he chemical within the brain. The psychological context of her health is how she copes and over comes the issues surrounding her disorder. The social context of her health is how her family, friends, andà community react to her disorder. On a daily basis she struggles to function adequately. She is now 37 years old and works as a substitute teacher, working on her masters, wife, and mother. Every day she wakes up feeling as though she could go back to sleep and did for the first two years. She could sleep eight to nine hours at night get her kids off to school then sleep all day till her kids get home. With the medication she takes now the day time sleepiness is not as severe, but can still be overwhelming some days. Imagine the social issues that can arise as a substitute teacher if her medication is not working and she falls asleep while with students. Trying to function with narcolepsy when life previous to the disorder consists of outdoor activities, energy, and multi-tasking can cause psychological issues. Having a strong social support system, following medical advice, and a strong will to succeed keep the woman psychologically strong. The woman does struggle in her academic life, but refuses to give up. So tir ed and rundown daily she fights thru any issues that arise from the disorder that now runs her biological, psychological, and social life. Although, her clock may lose time as a result of the nicked gears, she duck-tapes the nicks and reset her clock daily. Narcolepsy is a life altering, mysterious neurological disorder that can pose serious problems for the ones affected by it. à Although, there is no cure for narcolepsy research shows that with medication, education on the disorder, counseling, support from family members and friends, that there can be some relief from the symptoms. Conclusion Over time psychologist realized that focusing on one causal factor results in partial information for analysis of health and illness. Thus, the biopsychosocial model became the primary perspective used and was the focus of this paper. An understanding of the biopsychosocial perspective attained through a description of the systems and three contexts of this theory, examination of the influence of this theory on the biomedical viewpoint, and examination of how the interaction of biological, psychological, and social factors influence a personââ¬â¢s health. The hypothetical scenario looked at a woman with narcolepsy and the issues she faces daily from a biopsychosocial perspective. References: Albery, I. P., & Munafo, M. (2008).

The inter-relationship between fiction and imagination are critical in the defining the Vietnam war in OBriens book. War is real although the soldiers are fictional. The realities of war and its devastating effects are clearly defined from imaginations of the reader as depicted by the imaginary characters. OBrien purportedly asserts a piece of information to be factual and later confesses to it being fictitious is evidence that he is consciously aware of the use of both fact and fiction in writing his book. While advocating that stories can bring dead people back to life the dimensions of imagination and reality are further realized. In context dead people can only be imagined to be alive and live people will factually continue to exist as alive or dead people are actually dead and will factually remain to be dead. OBrien continually reaffirms to the reader about the authenticity of the story of Rat Kiley slowly killing a baby water buffalo and despite the fact that the reader knows pretty well that it is fictional they actually accept it as factual. Donââ¬â¢t waste time! Our writers will create an original "OBriens Lives Of The Dead Book Review" essay for you Create order The existence of social codes and contracts in the platoons become arbitrary. Thieves for example are punished by others to create fear in others in committing the same bad unacceptable acts in society. The relationship between Jensen and Strunk and the social contract they make is much evidence of the increasing social pressure caused by the ravages of war. Most of the social pressure in the book is evident in the quests to prove ones bravery. Another good example of the social pressure is in the intensity of war and honor is revealed when in chapter eight Curt Lemon has a tooth pulled out just to prove he is not afraid of the dentist. In chapter four Tim chooses to go to war to be seen as brave despite his fear and shame. Tim also feels the guilt and shame of killing a young man and sees nothing brave in the act. Most of the men join the army out of a need to fulfil their social obligation to society. Norman Bowker joined the war out of popular cultural pressure and the need to impress his father and the society with medals. He succeeds in getting all the medals except one and the social pressure continues to haunt him even after returning from the war evidenced in the need to be a good citizen and hold down a job and have relationships. The story on the Rainy River shows evidence of social pressure as he receives his draft notice and does not want to fight in a war he does not believe to be just. His peers have a motivating factor in his decision about the war and OBrien has fear of being ashamed before his peers. The decisions that OBrien makes to fight in the war and not to flee into Canada arise from the social influence his family and community have on him and what they would think of him if he does not fight in the war.

Physician Assisted Suicide Ethically Justified - 2126 Words
Physician Assisted Suicide Introduction, Outline and Reference Tracy Pietrzak Philosophy of Ethics Professor John Schmitz February 2, 2015 Introduction Is physician assisted suicide ethically justified? Physician-assisted suicide (PAS) is defined as ending oneââ¬â¢s own life by taking a fatal dosage of a substance with the direct or indirect assistance of a physician (MedicineNET.com, 2015). PAS is a very sensitive and controversial topic that raises many moral and ethical questions. While some feel that a person should be able to die with dignity and under their own terms, others feel that this is not a choice we can ethically make. PAS recently made national headlines when Brittany Maynard, a twenty-nine year old woman diagnosed with stage IV glioblastoma, went public with her plan to end her own life under Oregonââ¬â¢s Death with Dignity Act that was passed in 1997. Maynard legally received a prescription from her physician for a lethal dose of barbiturates and decided to end her life own life instead of suffering the painful death that loomed in her near future. She ended her own life on November, 3, 2014 with her fam ily by her side (Durando, 2014). There are many moral issues that surrounded Maynardââ¬â¢s decision and whether or not PAS is ethical, however it is important to understand both sides of the debate to truly get the entire picture of the complexity of this issue before making the determination if physician-assisted suicide is ethically justified.Show MoreRelated Physician-Assisted Suicide is Morally and Ethically Acceptable1160 Words à |à 5 Pages à à à The long time debate over medically assisted suicide, the presence of a doctor at a patientââ¬â¢s suicide, resurfaced again with the conviction of doctor Jack Kevorkian.à Kevorkian was convicted of second degree murder when he euthanized, or administered the injection himself, Thomas Youk on September 17, 1998.à Dr. Kevorkian, an advocate and practitioner of medically assisted suicides, has many opponents on the issue.

Information security - Information security is way of protecting information from being stolen or revised. All companies have secret information and they should protect them from other people who might take advantage of them. Once the security got hacked, it can lead companies to serious situations and they may face huge loss. Therefore the information security audit (IS audit) are intended to improve the level of information security to maintain a certain level of security in an organization. Information security audit - An information security audit is an audit of the organization s level of information security.(Wikipedia) It can be seen as a part of an information technology audit when centered on the IT aspects of information security.

Over Voltage and Under Voltage Control Using Relay Essay Sample free essay sample
IntroductionThe protection system is one O the of import facet on which major makers is concentrating. The companies like L A ; T. SIMENS etc. The protection system non merely provides lastingness to the equipment but besides avoid jeopardies. The protection system is one of the major Fieldss in the electrical technology. There are different types of protection systems out of that really common and of import 1 is the electromotive force protection system. Normally all the electrical equipments are specified with a specific electromotive force scope for its safe operation. When of all time those equipments are applied with a electromotive force more so the upper specified limit the system may pull extra current which may do to fire the equipment. The equipment is designed to defy a specific electromotive force when of all time the electromotive force goes beyond the bound value so automatically the insularities used in that equipment acquire punctured and do a harm to the equipment. Similarly whenever the equipment is applied with a electromotive force lower so the lower specified electromotive force it draws extra current to keep the efficiency. The out put may non be proper and the equipment may damage. The complete electromotive force and under electromotive force relay in combination protect the device from fluctuation of electromotive force. This type of relay provides the equipment complete protection against unsought electromotive force status. The complete electromotive force and under electromotive force relay is one of the of import protective relays which is used in the practical application at industries to protect motors transformers and other electronic and electrical equipment and power system. DESIGN PRINCIPLE:The complete electromotive force and under electromotive force relay is designed utilizing possible transformers ( PT ) . There is a PT used to try the line electromotive force and converts into DC value. The DC value obtained at the rectifier and filter out put is correspondent to the AC line electromotive force amplitude. The filter is designed with a clip invariable more so five clip period ( 5T ) . The sampling electromotive force obtained at the rectifier filter out put of the PT alterations after 5T merely. In this mode the sampling electromotive force is made immune to the effects of spiks. The sampled electromotive force is feed to two different comparators holding mention electromotive forces correspondent to the under electromotive force and over electromotive force scene. Whenever the sample electromotive force goes beyond the mention electromotive force set for over electromotive force status so comparator end product goes high and a mistake status is det ected. Similarly whenever the sample electromotive force goes bellow the mention electromotive force set for under electromotive force status in the other comparator the end product goes high and a mistake status is detected. The end products of both the comparators are feed to a logic gate to bespeak the mistake status when of all time any of the comparator issues a mistake determination. The out put of the logic gate is feed to the bistable / latch and so relay driver and doorbell driver to protect the equipment from the mistake status and bespeak the mistake happening by blowing the doorbell. CIRCUIT DESCRIPTIONa. Power supply Circuit connexion: ââ¬â In this we are utilizing Transformer ( 0-12 ) v. 1Amp. IC 7812. rectifying tubes In 4007. LED A ; resistances. Here 230V. 50 Hz ac signal is given as input to the primary of the transformer and the secondary of the transformer is given to the span rectification rectifying tube. The o/p of the rectifying tube is given as i/p to the IC regulator ( 7812 ) through capacitance ( 1000mf/35v ) . The o/p of the IC regulator is given to the LED through resistances. Circuit Explanations: ââ¬â When ac signal is given to the primary of the transformer. due to the magnetic consequence of the spiral magnetic flux is induced in the spiral ( primary ) and reassign to the secondary spiral of the transformer due to the transformer action. â⬠Transformer is an electromechanical inactive device which transformer electrical energy from one spiral to another without altering its frequencyâ⬠. Here the rectifying tubes are connected in a span manner. The secondary spiral of the transformer is given to the span circuit for rectification intents. During the +ve rhythm of the ac signal the rectifying tubes D2 A ; D4 behavior due to the forward prejudice of the rectifying tubes and rectifying tubes D1 A ; D3 does non carry on due to the reversed prejudice of the rectifying tubes. Similarly during the ââ¬âve rhythm of the ac signal the rectifying tubes D1 A ; D3 behavior due to the forward prejudice of the rectifying tubes and the rectifying tubes D2 A ; D4 does non carry on due to reversed prejudice of the rectifying tubes. The end product of the span rectifier is non a power District of Columbia along with crinkled Ac is besides present. To get the better of this consequence. a capacitance is connected to the o/p of the rectifying tubes ( D2 A ; D3 ) . Which removes the unwanted ac signal and therefore a pure District of Columbia is obtained. Here we need a fixed electromotive force. thatââ¬â¢s for we are utilizing IC regulators ( 7805 A ; 7812 ) . â⬠Voltage ordinance is a circuit that supplies a changeless e lectromotive force regardless of alterations in burden current. â⬠This ICââ¬â¢s are designed as fixed electromotive force regulators and with equal heat sinking can present end product current in surplus of 1A. The o/p of the span rectifier is given as input to the IC regulator through capacitance with regard to GND and therefore a fixed o/p is obtained. The o/p of the IC regulator ( 7805 A ; 7812 ) is given to the LED for indicant intent through resistance. Due to the forward prejudice of the LED. the LED freshnesss ON province. and the o/p are obtained from the pin no-3. B. Under voltage/over electromotive force sensor In this subdivision our purpose is to observe the line changing electromotive force. The line electromotive force ( 230vac ) coming from the brinies is to be step down that electromotive force with the aid of a measure down transformer. If the line electromotive force varies. the measure down electromotive force besides varies in conformity with the input electromotive force. Due to the common initiation of the transformer. if the primary twist of the transformer electromotive force is more the flux induced is more and the secondary electromotive force is more. Similarly. if the primary twist of the transformer electromotive force is less the flux induced is less and the secondary electromotive force is less. In this manner under/over electromotive force occurs. The above figure shows a half-wave rectifier. in which it will change over Ac to dc electromotive force. We can change the electromotive force with the variable burden opposition ( 10k ) The sample electromotive force can be calibrated by changing the burden opposition RL The of import portion of this design to try the electromotive force accurately as an reproduction of the line electromotive force. The measure down transformer samples the line electromotive force at a decreased signal electromotive force Vac = ( N2/N1 ) *VL The DC electromotive force after the half moving ridge rectifier is about Vm due to the charging of the capacitance. this capacitance electromotive force represents the line electromotive force. The clip invariable of the circuit is defined by C*RL. The clip invariable of the circuit must be more so five times of the clip period of the signal. RC gt ; 5T. If the RC value is less the 5T so the sample electromotive force fluctuates unnecessarily. if the RC value is excessively high the trying response becomes excessively slow. Operation: The end product of the signal sampling electromotive force ( 3v ) goes to the input of both of the comparator. In the first comparator we have set the electromotive force say 3. 5Vto the non-inverting terminus. In this instance non-inverting terminus is greater than the inverting terminus. That means end product of the first comparator is Low. At present under temperature can ( t be done because the room temperature will be ever available If we want ( s to make under temperature. we have to change or alter the set point which is connected to the inverting terminus of that comparator. Similarly. for the 2nd comparator we have set the electromotive force say 4V to the inverting terminus. In this instance inverting terminus is greater than the non-inverting terminus that means end product of the 2nd comparator is HIGH. If the temperature increases. the corresponding electromotive force will increase state 4. 5V. That electromotive force goes to the input of both of the comparator. In the first comparator we have set the electromotive force say 3. 5Vto the non-inverting terminus. In this instance inverting terminus is greater than the non- inverting terminus. That means end product of the first comparator is HIGH this means that over temperature has occurred. Similarly. for the 2nd comparator we have set the electromotive force say 4V to the inverting terminus. In this instance non- inverting terminus is greater than the inverting terminus that means end product of the 2nd comparator is LOW. c. NOR gateOR GateThe OR gate is besides called as ââ¬Å"any or allâ⬠gate. The OR gate is the combinable logic circuit which has merely one end product and may hold any figure of inputs. The end product is when any one or more than one of the input is 1 and the end product is 0 merely when all the input is 0. In the above figure. a rectifying tube OR gate is shown. It is clear from this circuit if at A +5v input is applied. it will send on colored transistor diode-1 and the end product electromotive force at C will be +5v i. e. . if input A is 1. the end product C will besides be 1 irrespective of input B. likewise. if input to B is 1. the end product at C will besides be 1. irrespective of input to A. the end product C will be 0 merely when both the rectifying tubes are nonconductive i. e. both input are 0 i. e. A=0 and B=0 NOT GATE Introduction: The application of the transistors is non limited entirely to the elaboration of the signals. Through proper design transistors can be used as switches for computing machines and control applications. The web of figure-01 ( a ) can be employed as an inverter in computing machine logic circuitry. Note that the end product electromotive force Vc is opposite to the applied to the base or input terminus. In add-on note the absence of dc supply connected to the base circuit. The lone District of Columbia beginning is connected to the aggregator or end product side. and for computing machine applications is typically equal to the magnitude of the ââ¬Å"highâ⬠side of the applied signal ââ¬â in this instance 5V. Operation: Proper design for the inversion procedure requires that the operating points switch from cut-off to impregnation along the burden line depicted in above figure ( B ) . For our proposes we will presume that IC = ICEO = 0mA. when IB = 0à µA ( an first-class estimate in visible radiation of bettering building techniques ) . as shown in above figure ( B ) . In add-on. we will presume that VCE = VCE sat = 0V. When Vi = 5v. the transistor will be ââ¬Å"ONâ⬠and design must see that the web is to a great extent saturated by a degree of IB greater than that associated if the IB curve looking near the impregnation degree. In the above figure ( B ) . this requires that IB gt ; 50à µA. The impregnation degree for the aggregator current for the circuit is defined by. IC = VCC ââ¬â VCE / RC= 5V ââ¬â 0. 2V / 10K= 480à µA The degree of IB in the active part merely before impregnation consequences can be approximated by the undermentioned equation. IB min ? IC sat / ?dc=480à µA / 300=1. 6à µAFor the impregnation degree we must therefore insure that the undermentioned status is satisfied: IB max gt ; IC sat / ?dcFor the web of the above figure ( B ) . when Vi = 5v the ensuing degree of IB is AssumeIB = 100à µA5v ââ¬â RB IB ââ¬â 0. 7v = 0RB ( soap ) = 4. 3 / 100à µA = 43k?RB ( min ) = 4. 3 / IB ( soap ) = 1k? Which is satisfied. Surely any degree of IB greater than 16à µA will go through through a Q- point on the burden line that is really near to the perpendicular axis. d. Bistable / LatchIntroductionThe latch is the electronics device which shops the province even if the input is with drawn. So this ca be started as a individual memory unit. The latch can be designed in many ways by utilizing a discreet constituent or reversal or a IC known as 555 timer. The Latch designed utilizing 555 timer IC is rather stable. Ckt Connection: The threshold electromotive force pin-6 of IC555 is connected to land and the trigger pin-2 a pull-up resistance 10k is connected to VCC usually. Whenever the threshold electromotive force is low. the end product of the comparation-1 hellishly. the end product of the flip-flop goes low. And the input of the comparator ââ¬â 2 internally high than 1/3 Vcc. the end product will stay in ââ¬ËLOWââ¬â¢ sate. Whenever a negative border trigger electromotive force will look at the trigger pin-2. internally the end product of the comparator ââ¬â 2 goes high. the reversal will stay in high province and it will latch that end product. Until we have to reset that IC through reset pin-4 to land. Operation The 555 timer IC contain two comparators at its input. one terminal of the comparator is connected to the 1/3 Vcc and 2/3 Vcc severally. The other two terminus of both the comparator are named as trigger and threshold. The end product of these two comparators are connected to a S-R somersault ââ¬âflop in which end product toggles when the inputs are dissimilar i. e. 1. 0 or 0. 1. The Bistable design gas two inputs. one as trigger input to alter the province and the other is to reset the end product. The input signal is connected to the trigger pin and the threshold is grounded. It means the end product of the comparator to which 2/3 Vcc is connected and threshold ( land ) is kept at fixed end product. When the trigger pin is issued with an input which is less than 1/3 Vcc so automatically the comparators end product toggles and therefore the somersault floating-point operation end product toggles and the end product of the 555 timer IC is set. The end product remains in the provi nce until unless the reset input is pulled down to land. e. Relay driver In this subdivision we have taken electro magnet relay to command the electrical contraptions we have taken a 12v relay whose opposition is 400? which requires 30mA current to drive or to do it ââ¬ËONââ¬â¢ / ââ¬ËOFFââ¬â¢ . The end product of the reversal is given as input to the relay driver ( as we know. the end product of the reversal is a TTL IC which gives a end product current 50à µA. Therefore. we need a driver ckt to drive the relay. The driver is configured as a transistor acts as a switch. Whenever the base electromotive force is high through a base opposition 1. 5 K and the aggregator is connected to the relay spiral. which as a opposition Rc 400? . the transistor comes to saturation status i. e. ââ¬ËONââ¬â¢ province because the emitter current will flux to the aggregator part. which makes the spiral as electro magnet. The relay driver is design by utilizing a BC547 transistor. The relay used here holding the specification as follows ? Coil opposition =400ohm? Coil voltage=12Vdc? Contact capacity=230V. 7AThe above specification indicates that the spiral requires 12V District of Columbia and 200mA current District of Columbia. The TTL canââ¬â¢t supply more so 20à µA current. So driver subdivision is really much required. BC547 has a typical current addition of 200 and maximal current capacity of 1A. So a typical base current of 10 ( A can trip to on the relay. ELECTRO MAGNETIC RELAY These are really much dependable devices and widely used on field. The operating frequence of these devices are minimal 10-20ms. That is 50Hz ââ¬â 100Hz. The relay which is used here can care 25mA currents continuously. The electromagnetic relay operates on the rule magnetic attraction. When the base electromotive force appears at the relay driver subdivision. the driver transistor will be driver transistor will be driven into impregnation and let to flux current in the spiral of the relay. Which in bend create a magnetic field and the magnetic force produced due to that will move against the spring tenseness and shut the contact spiral. Whenever the base electromotive force is withdrawn the transistor goes to cutoff. So no current flow in the spiral of the relay. Hence the magnetic field disappears so the contact point interruptions automatically due to spring tenseness. Those contact points are isolated from the low electromotive force supply. so a high electromotive force shif t is possible by the aid of electromagnetic relays. The electromagnetic relays usually holding 2 contact points. Named as usually closes ( NC ) . usually unfastened ( NO ) . Normally closed points will so a short CKT way when the relay is away. Normally unfastened points will so a short CKT way when the relay is energized. f. Buzzer driver The doorbell driver consists of a doorbell A ; its driving ckt. It works on the rule of transistor action ( Transistor acts as a switch ) . When the base electromotive force is high. the transistor comes to saturation i. e. in ON status. which drives the doorbell because a little emitter current will flux. Similarly. when the base electromotive force is low. the transistor does non come to saturation i. e. OFF status. which does non drives the doorbell. Future ExpansionThis undertaking is designed with restriction to clip and cost. The complete electromotive force and under electromotive force relay that is designed here can be modified to interface multiple parametric quantities such as temperature and current etc. The interface of micro accountant can do the system more various and smarter. Decision The complete electromotive force and under electromotive force relay that is designed here in the research lab and tested in the research lab status. And found to be runing satisfactory the set points are set at the restricting value and the practical tripping of the relay is within the bounds of experimental mistakes.
