Effective Communication For Managers â⬠MyAssignmenthelp.com
Question: Discuss about the Effective Communication For Managers. Answer: Introduction In the present day scenario, it is important for the managers to inculcate several important managerial skills within him. It is only after he has started practicing the skill that he can implement it within his employees as well. There are many important qualities that manager must inculcate within himself-they are critical thinking, planning, coordinating, cooperating, following up, determined and also communication. Communication happens to be the most essential and basic managerial skill. Communication is the very key to management. If the communication does not take place freely and from both the ends then the entire process of communication remains incomplete. Effective communication is indeed a very useful tool. Being a manager, it must be his utmost priority to effectively communicate with all his employees. This will make the employees very free within the office environment (Shen Austin 2017). Theoretical concepts The ability of the manager to successfully communicate with their superiors, colleagues and other employees are important irrespective of the industry one works in (Austin et al., 2013). However, communication skills are very important for any manager to ensure their success (Dozier, Grunig Grunig, 2013). Thus, the top 10 communication skills that can help the managers to understand the present job market is as follows- Listening- to be a good communicator it is important to be a good listener first. Managers who are good listeners are always preferred more by others as they will listen to others as well. Thus, active listening skill plays an important role for the managers where they pay close attention to what the other person has to say. Non-verbal communication- body language, eye contact, hand gesture and the voice tone all pay an essential role in what an individual is trying to deliver. Thus, for a manager the tone should be relaxed, friendly and open stance where the other employees must feel that he is approachable and these non-verbal communication elements will influence others to express openly in front of the manager (Burgoon, Guerrero Floyd, 2016). Clarity and concision- a manager who are good communicators never say too little or way too much while communicating rather they just say as much as they need to. The best possible way is to convey messages in little words as possible. Clear and direct messages are important from the manager's side to be it on phone, in person or through emails. Friendliness- managers who have a friendly tone, personal questions or may be simply a smiling face can greatly encourage their coworkers to attract them in open and honest communication with their managers. Confidence- while interacting with the employees, managers must be confident while they are interacting with others. Thus, confidence in the managers makes the co-workers feel that the manager believes and will follow what he believes. Confidence is reflected through the managers eye contact while taking, firm and friendly tone (Davidson Stevens, 2012). Empathy- managers need to understand and respect the point of view of the employer, the co-worker or the followers. Thus, listening to others and respecting their point of view is important on the managers part. Open-mindedness- for a manager it is very important to have a flexible and open mind to be a good communicator. Thus, managers must be open to listening and honest when they are conversing with others. Respect- managers must show respect to other employees as well as to their ideas. To show respect managers should take the name of the worker, make eye contact while conversing and listen actively while conversing. Feedback- managers must have the skill so that they can properly give and take feedback from others. Feedback, however, is an important skill area for the managers. Managers, as well as the supervisors, should repeatedly search for different ways in which they can provide their co-workers with feedbacks that are constructive. Picking the right medium- the most important thing in communication by the managers is to have the knowledge where they can use the correct form of communication in the correct situation. There are few communication theories which can help the managers and the organization determine their culture of the organization. Thus, there are following four theories of communication- Critical theory- according to this theory the communication takes on the role where it can settle conflicts, avert problems between a set of individuals, motivating the employees so that they can do more and lastly, imparting direction that will unite the workforce under one goal (Baynes, 2013). Information theory- this theory mainly deals with the way information proceeds with as little mistake possible. Here communication mainly focuses on the massages so that they can be mended so that it cannot be modified. It, however, confirms the accuracy of the communication. Moreover, one can hold the recipient of the message as more responsible than the sender who is responsible for the final statement of the communication. Post-positive theory- this theory puts attention on messages intended to keep employees obeying the rules and then smoothly working altogether. The post-positive theory basically thinks that order is a natural condition in any company. Groupware theory- as technology advances there are high chances where old lines of the communication may get modified. Thus, staffs can communicate via computers, mobiles, and other technologically advanced devices so that the information's are spread in organizations ahead of the desire of the management. However, there can be situations where information's that are positive can also flow from one department to the other before themanagement can notify the stakeholders of the modifications in any policy or in any initiative (Leonardi, 2014). Implications of communication in effective management practices Communication is the main element to succeed as a human resource management (HRM) or as a manager. In HR communication has an effective part to play because HRM is solely based on the effective communication practices. However, an effective communication is the essential element for human resource leaders. However, communication must be in sync along with the managers; managers with its employees so that it can support the internal as well as the external service to the customers, manage alterations within the company and build the unity of the HR department (Bratton Gold, 2012). Thus, the benefits that the manager can bestow in the organization through practicing effective communication are as follows- Intradepartmental communication- this point says that HR managers must learn themselves to productively communicate with the companys workforce. However, they are also bounded to strengthen the lines of communication among the HR leaderships and HR staffs. When the communication is done through an HR manager effectively with their employees then they together portray as a team with a steady mission that can begin HRs integrity throughout the company (Gondal Shahbaz, 2012). Strategic Direction- the HR managers who are among the high-level ones usually communicate with the topmost managers. In a company that utilizes the HR department leadership as a guide to creating a productive and attentive workforce, the HR managers manifest partnerships with the topmost leaders so that they can develop the organization's strategic direction. However, if there is an inability in the communication with the executives then HR risks them as not becoming a member of the team who will be responsible for defining the company's strategic growth and functional applications of their strategic plan. Functional implementations- the expertise of an HR manager is frequently demonstrated via communicating their knowledge of their job along with their best practices and their professional vision for the department and the company all over. The benefit of effective communication is that the functional application is suitable for the strategic direction of the organization and that the HR employees evidently understand how to proceed forward under the guidance of HR manager. Effective leadership- effective communication benefits the leadership of the HR manager. HR managers those who are competent of empowering the administrators and managers in the areas like the first responders for staffs relations matters, alleviate HR employees to handle many of the routine problems that appear within the department itself. However, HR expands and delivers leadership training as well. Communication benefits risk management- apart from the above-mentioned benefits there are other benefits and they are that HR leaders minimize the organization's liability for inequitable employee practices. Communicating the company's policy on equal staff opportunities and justifying decisions of the employees with appropriate documentation is also another feature or benefit for effective communication within the organization. However, communicating the policies of the company to its various departmental employees so that they understand the organization's commitment towards fair and equal treatment, despite their sex, race, religion, and disability (Hopkin, 2017). However, communication is very much essential in effective management practices in an organization. Communication needs to travel in all directions throughout the organization like from managers to their employees, from the employees back to the managers and also in between the team members. An effective manager is the one who can be an active listener and encourages a surrounding where the employee gets to know each other and believes in one another's strengths, weaknesses and their styles of communication (Block, 2016). However, effective management is a skill, but still, it can be learned if some basic principles are followed. Therefore the following steps can help develop managers:- Selecting the appropriate employee Showing empathy Clear communication with the employees Managers must lead by examples Managers must know how to delegate work to their team members so that their teammates also get the chance to contribute to some important projects. Managers must be positive as well as constructive Managers must thank their employees as well as reward back them for good work Managers must look after the development of their employees; they have the patience to guide them for betterment. Motivating innovations Managers must have a flexible approach so that they can adopt with various types of employees and granting them the freedom to work in their own styles. As mentioned in the first part of the report, communication is one of the most important qualities that a leader must have. As the very name suggests, the manager is someone who has to manage all the affairs of an organization. Hence, communication naturally becomes a very important trait or a skill area of the manager. It is also a very well known fact, that all the employees who come to work in any and every organization, are from different cultural and social backgrounds. Hence, it often becomes very difficult for them to understand the different rules and regulations of the company. However, implementing proper principles of communication will definitely help to make the employees very much comfortable within the office environment (Mazzei , 2014). As a manager, it must be the first and foremost duty to see if his employees are happy and comfortable within the office and also to ensure that the employees clearly understand the exact reasons behind the rules and regulations of the company and why must they abide by them. An essential outcome of having a good communication skill helps in answering the question "why". In other words, the employees often suffer from several unanswered questions like why must they care about the company rules, why must they be hundred percent efficient in their work, why is it important to not take unnecessary leaves, why is it important to keep the important company information confidential etc. It is through this effective communication skills that a manager can solve all these questions. He can talk with all these employees individually and listen to all their concerns. Not only that, it is only through effective communication that he will be able to solve all the doubts and fears that the employees have. Another important outcome of implementing a good communication in the workplace is preventing the process from being a onetime event. Implementing proper communication skill at each and every level of the company will make this process a two-sided one. In other words , effective communication is one that always will have a positive outcome from both ends that is from the sender as well as from the receiver. In other words, if the manager is making any kind of announcement or is circulating any email among his employees, it is the sole duty of the employees to see and revert back to them as well. Getting a proper feedback from all the employees will ensure that the process of effective communication has been successful. Communication type Objective Medium frequency audience Owner Deliverable Inculcate effective speaking within the employees by introducing a project To initiate communication and enable the employees in giving up hesitation Face to face once Project Sponsor Stakeholde-rs Project team Project manager Agenda Meeting minutes Involving all the members in giving the project review To involve all the team mates and make communication a two way process Face to face Conference call As needed Project team Project manager Agenda Meeting minutes Taking report of the project individually from all the team mates To listen to and cater to all the problems of each and every employee Face to face interaction Personal meeting Daily Weekly monthly PMO Project manager Employee feedback Communicating with a friendly body language and gestures for imbibing positivity Helping to reduce the negative vibes from the employees, cheering them up with positivity and helping them to restore their confidence and productivity Face to face presentatio-n daily All the employees Project manager Project status report Another important outcome of implementing effective communication within the organization will also ensure that the employees are getting whatever is being communicated to them by their superiors or their managers. Apart from this, another important outcome of this effective communication will be to get the feedback from the employees (Holmes, Atherton Tweed 2014). If the managers are freely communicating with all their employees, it will make the employees feel very much wanted. It is only as a positive outcome of effective communication that the manager will ask for the active participation of the employees in any and every big or small decisions taking place within the organization. This will help the employees in knowing that they are very much valued within the organization. A sound and effective communication system will help in grooming the trust and confidence of the employees both within themselves and within the organization as well (Belsha et al., 2017). This will in turn help in increasing the productivity of the employees. Achievements Implementing effective communication within the organization will definitely have some positive achievements Building long-term relationship Offices are not only the place where people come for working; they also make friends in one's workplace. Apart from working hard, it is also very much essential for the employees to develop friendly relationships. Having a good trust and a long-standing relationship is very much essential for maintaining a healthy work atmosphere as well (Carr et al., 2016). Breeds trust It has been seen that the employees tend to open up more when they meet face to face than when they communicate through technological means. The groups that meet and talks face facing build up more trust and effective cooperation between themselves. Communication helps in using several friendly gestures and body languages as well ( Hashim 2015). These include a formal hug or a handshake or a pat on the back just in order to show respect and a token of friendliness, faith, respect, and understanding. These help in generating the feeling of positivity within the organization (Raina Roebuck 2016). Often there are several negative opinions and negative comments that the employees get to hear from their co-workers or even their superiors. These negative vibes often take away the positive mood from the employees. This negative vibe may render the entire day bad and ineffective. It is during this time, that a good and comfortable communication helps a lot. It helps in encouraging and motiv ating the employees a great deal. (Fan et al., 2015) Problem-solving skills Both effective communication and the problem-solving skills go hand in hand. It is often seen that some of the employees within an organization are hesitant in many affairs. They naturally look to their leaders or their managers for guidance and help. If the managers fail to talk freely with their employees then he is likely to lose the trust of his employees. He needs to freely engage in a conversation with all his staff and listen to all their doubts patiently (Vihakara 2014). He must also try his level best to make them speak and open up. He must encourage his employees not to stay quiet regarding their issues and problems. Communication is always the best tool to come put from shyness and open up freely in one's work environment. This will enable the manager to know about all the problems that his employees are facing in the workplace. Multigenerational relations It is a proven fact that in any and every work field, there will obviously be several areas of conflict. However, these conflicts can often arise between the employees due to o many reasons. It will be the duty of the manager to see to this and solve this problem. Good communication skills will definitely help the manager to easily manage this problem. It is only through communication that the manager can overcome such complicated situations and encourage his employees to give up the disputes between themselves and work peacefully. Maintaining industrial peace Communication will definitely help in solving all the disputes taking place between the employees. There are also several attitudes that can be used in an organization for getting the positive outcomes of effective communications. Often the employees suffer from some of their personal tensions as well. These personal problems mingled with the work pressure create a very bad impact on their mood and this, in turn, can affect their productive capacities as well. If the manager takes a good initiative and starts communicating with all his employees then it will really be very helpful. Sharing and opening up will definitely make the employees much relieved from their tensions and they will naturally be able to work with a cheered up mood. This, in turn, will enhance the productivity of all the employees and the entire operation of the organization will be running smoothly (Helfat Peteraf 2015). Conclusion Thereby it can be concluded from this paper that effective communication is very much important in each and every aspect of an organization. It is of utmost importance on part of a manager to imbibe this skill of effective communication within him. Among all the good qualities that a manager must contain, communication is one of them. Communication is the building block of a successful and well-functioning working organization. Though effective communication is not a very easy process to be implemented and followed within the first go, gradually kit must be started. A manager can himself start communicating with all his employees one by one. This will not only make him know all the doubts and complaints of his employees but it will also make the employees feel very much wanted. The managers will be able to win over the trust of his employees. This will assure the employees that they are valued within the organization. This will increase the self-confidence of the employees and conseq uently, their overall production will also be increased. References Austin, M. J., Regan, K., Gothard, S., Carnochan, S. (2013).

Ai - Edge Of Excellence Essays - Artificial Intelligence
Ai - Edge Of Excellence Essays - Artificial Intelligence Ai - Edge Of Excellence Running head: The Edge of Excellence The Edge of Excellence Kathleen P. Munn Community College of Philadelphia Recently, the media has spent an increasing amount of broadcast time on new technology. The focus of high-tech media has been aimed at the flurry of advances concerning artificial intelligence (AI). What is artificial intelligence and what is the media talking about? Are these technologies beneficial to our society or mere novelties among business and marketing professionals? Medical facilities, police departments, and manufacturing plants have all been changed by AI but how? These questions and many others are the concern of the general public brought about by the lack of education concerning rapidly advancing computer technology. Artificial intelligence is defined as the ability of a machine to think for itself. Scientists and theorists continue to debate if computers will actually be able to think for themselves at one point (Patterson 7). The generally accepted theory is that computers do and will think more in the future. AI has grown rapidly in the last ten years chiefly because of the advances in computer architecture. The term artificial intelligence was actually coined in 1956 by a group of scientists having their first meeting on the topic (Patterson 6). Early attempts at AI were neural networks modeled after the ones in the human brain. Success was minimal at best because of the lack of computer technology needed to calculate such large equations. AI is achieved using a number of different methods. The more popular implementations comprise neural networks, chaos engineering, fuzzy logic, knowledge based systems, and expert systems. Using any one of the aforementioned design structures requires a specialized computer system. For example, Anderson Consulting applies a knowledge based system to commercial loan officers using multimedia (Hedburg 121). Their system requires a fast IBM desktop computer. Other systems may require even more horsepower using exotic computers or workstations. Even more exotic is the software that is used. Since there are very few applications that are pre-written using AI, each company has to write it's own software for the solution to the problem. An easier way around this obstacle is to design an add-on. Neural networks have entered the spotlight with surprisingly successful results. A neural network is a type of information processing system whose architecture is similar to the structure of biological neural systems (Butler and Caudill 5). The neural network tries to mimic the way a brain and nervous system work by analyzing sensory inputs and calculating an outcome. Before it can be used a neural network must be trained. Some can learn by themselves, some require training by doing, and others learn by trial and error. A computer learns by naturally associating items the computer is taught and grouping them together physically. Additionally, a computer can retrieve stored information from incomplete or partially incorrect clues. Neural networks are able to generalize categories based on specifics of the contents. Lastly, it is highly fault tolerant. This means that the network can sustain a large amount of damage and still function. This type of system is inherently an excellent des ign for any application that requires little human intervention and that must learn on the go. Created by Lotfi Zadeh almost thirty years ago, fuzzy logic is a mathematical system that deals with imprecise descriptions, such as new, nice, or large (Schmuller 14). This concept was also inspired from biological roots. The inherent vagueness in everyday life motivates fuzzy logic systems (Schmuller 8). In contrast to the usual yes and no answers, this type of system can distinguish the shades in-between. This system provides a smart light that can decide whether a traffic light should be changed more often or remain green longer. In order for these smart lights to work the system assigns a value to an input and analyzes all the inputs at once. Those inputs that have the highest value get the highest amount of attention. Another promising arena of AI is chaos engineering. The chaos theory is the cutting-edge mathematical discipline aimed at making sense of the ineffable and finding order among seemingly random events (Weiss 138). The theory came to life in 1963 at the Massachusetts Institute of Technology. Edward Lorenz, who was frustrated with

Factors that influence Major League and Minor League Baseball
Factors that influence Major League and Minor League Baseball Introduction The field of games is a rather demanding area that calls for a fair deal of devotion if one is to succeed in it. Games come in different categories. However, inasmuch as each category wishes to attract fans based on its records of fabulous performance, it is crucial to note that various factors boost and or lower the performance.Advertising We will write a custom research paper sample on Factors that influence Major League and Minor League Baseball specifically for you for only $16.05 $11/page Learn More The paper narrows down to the baseball game. Major league and minor league baseball attendance are affected by a myriad of factors ranging from the motivational factors that attract fans, to ticket pricing. In between these two extremes, scholarly works have shown a number of factors to be significant in influencing the attendance in baseball matches. Meehan, Nelson and Richardson (2007, p.572) sheds light that, ââ¬Å"A host of factors influenc es the demand for sports, including the price of tickets, fan income, the population of the drawing area, team quality, and the age of the stadiums in which teams playâ⬠. Other factors include crowd control, parking, and concession. These factors are what researchersà have referred to as environmental factors. Fans of a given sport differ enormously from fans of another sport and hence the factors that affect their attendance in the matches are widely controlled to a different extent by the same factors. What this means is that one factor may have positive effects in drawing the spectators to cheer up a given match while in a different sport, it may produce the opposite effects. With this in mind, this paper introspect the factors that affect sports attendance with reference to principal and minor baseball league. The complexity and magnitude of promotions and marketing of entertainments products during the matches ardently influence major baseball leagues. Other factors that are given consideration in the paper includes but not limited to team quality, top prospects, ticket pricing, prospects of terrorism, influence of international players and location of base ball facilities. However, these factors widely act in a combination mode and hence they influence attendance compositely. Major and minor baseball league attendance Promotions Various scholarly works have confirmed promotions to increase attendance of baseball contests. Various types of promotions, however, influence attendance differently. As Gitter and Rhoads (2011, p.345) claim, ââ¬Å"While price promotions affected attendance negatively in all clubs, non-price and combinations of promotions were associated with an increase in attendance for all teams.â⬠Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Butler conducted a study of determinants of the minor games attendance in 2006 Carolina baseball league. The analysis of the study predominantly focused on the effect of different promotions conducted during the game day, as opposed to promotions conducted throughout the season. In this regard, Butler (2002, p.328) posits that, ââ¬Å"The operation of Major League Baseball (MLB) teams is a remarkably complex enterprise involving the marketing of a diverse multi-dimensional entertainment commodity. Apart from promotion of concession products: soft drinks, hot dogs and the likes, promotion of home teams tickets increases the attendance for home teams fans. Increased buying power goes hand in hand in the provision of the positive response to promotional campaigns. Arguably, the demand for tickets and hence the attendance during minor baseball leagues is impeccably affected by income per capita. Butler (2002, p.328) reckons that, ââ¬Å"the higher the per capita income in the host county (or host city) for a minor league team, the greater demand for tickets in th at county.â⬠Attendance for minor base ball league, consequently, is a function of factors that affect the demand for the home team tickets and the factors that impede the promotion of the home team entertainment products. Using the data generated form Carolina baseball league attendance in the year 2006. Butler (2002, p.334) found out that ââ¬Å"attendance, expressed in relative terms as a number of persons in attendance as a percent of stadium capacity was directly related to the per capita income of the county or the city of the host teamâ⬠. The attendance was also a function of the other benefits such fare deals of foods and drinks products. Reduction of food and drinks prices sold during the matches and other products for home teams such as caps, T-shirts are promotion endeavors, which have a tremendous capacity to draw a substantial volume of attendance (Gifis, 2006, p.513). Scheduling the games on Saturday and Fridays has also the capacity to increase attendance. C onsequently, given the capacity of the promotions to increase the attendance, combining the two has an ability to raise the attendance even more. Team quality Team quality affects not only major league baseball attendance, but also minor league attendance. According to Gitter and Rhoads (2010) ââ¬Å"there is evidence that minor and MLB are substitutes as increased ticket prices for the nearest MLB team lead to higher minor league attendance if that team is within 100 milesâ⬠(p.620). Most fans interpret quality of the team as reflective of its performance. Maintained satisfactory performance stands a perfect chance of increasing the teamââ¬â¢s attractiveness before the eyes of its supporters.Advertising We will write a custom research paper sample on Factors that influence Major League and Minor League Baseball specifically for you for only $16.05 $11/page Learn More A study conducted by Greenstein and Marcumin 1982 revealed that major baseball att endance was a function of win-loss record in previous matches (Kahane Shmanske, 1997, p.427). In the variance of attendance, 25% of it was accounted for by the teamââ¬â¢s record of performance. Attractiveness or rather the quality of the team plays pivotal roles in making the decision to attend. Arguably, the fans of given Baseball team whether in major or minor leagues attend games to celebrate the winning of their team. In case a team has been recording losses more than wins, most of the fans will tend to shun from attendance since they do not want to be part of loss. This perhaps leads to the appreciation of the significance of considering the teamââ¬â¢s quality in determining the attendance of major and minor Baseball league. As Kahane and Shmanske (1997, p.434) reckon, ââ¬Å"The attractiveness of the visiting team (its quality, the presence of star players, the strength of its rivalry with the home team, etc.) is a second crucial factor in fans decision making about gam e attendanceâ⬠(p.40). Congruent with this view, if a visiting team has recorded a negative record in terms of performance, most likely the home team fans are likely to attend in large numbers even though the visiting team might have not held contests previously with the home team. According to Gitter and Rhoads (2010) ââ¬Å"â⬠¦local or regional MLB teamââ¬â¢s winning percentage only has a positive impact on minor league attendance when they are affiliated clubsâ⬠(p.614). Thus, it is plausible to argue that affiliation of teams coupled with fans perceptions about their teamââ¬â¢s quality has an impeccable influence in determining whether to attend or not to attend a major or minor Baseball league competition. Top prospects The existing enthusiasm among fans to see the future baseball star contributes to increased attendance during the minor leagues. According to Gitter and Rhoads (2010), ââ¬Å"Baseball America, a leading industry publication, ranks 100 top pro spects that have yet to play substantially in the principal leaguesâ⬠(p.614). For a whole year, the one hundred prospects develop within their localities before taking part in major leagues. Fans attend baseball minor leagues driven by enthusiasm to have a glimpse of the likely star to take part in the major leagues. The study conducted by Gitter and Rhoads claims that ââ¬Å"only those prospects ranked in the top five and the highest AAA have an impact on their teamââ¬â¢s attendance and their impact on attendance is smallâ⬠(2010, p.615). From these results, it follows that for those stars rated least in the Baseball America ranks for top 100 prospects have little capacity to draw fans attention and hence attendance during their minor base ball leagues.Advertising Looking for research paper on health medicine?

Get your first paper with 15% OFF Learn More Arguably, this is perhaps because the majority of the fans interpreted the ranking as likely indication of how such prospects would perform during the matches. This argument consequently takes us to the idea that fans would like to be associated with winning teams rather than losing teams. Since motivation is essentials in any game, the best prospects have the ability to produce baseball stars during the major leagues. Fans produce this motivation since their large attendance serves to give the players the belief that they are the best in the ranking as put forward by Baseball America. It is somewhat subtle to argue that, if top prospects can increase minor league attendance, them if these prospects happens to participate in the major league then, there is no doubt that the attendance will also be high. Unfortunately, this argument tend to infer that only those that who are ranked high by Baseball America have the chances of being Baseball stars during major leagues. Even though, th e ranking of baseball prospects by Baseball America may increase the attendance percentage according to various scholarly studies, the increment is minimal. According to Gitter and Rhoads (2010), ââ¬Å"minor league Baseball player ranking by Baseball America as top prospects increases attendance for minor league team by a minimal amount (less than 2%)â⬠(p.621). However, even though this increment is small, its contribution to sporting facilities revenues increment is quite significant. This is particularly pertinent since most of this revenue goes into improvement of sports facilities. In fact, new facilities have indicated their ability to increase attendance of fans both in minor and major baseball leagues (Roy, 2008, 146). Fear of Terrorism Sporting facilities are crucial targets of terrorist activities. Consequently, various sporting managers anticipate all range of consequences in term of fans attendances especially with increased perceptions and fears of terrorism activ ities. Kalist (2010) laments that, ââ¬Å"sports venues may experience falling ticket sales as the public becomes more concerned about the threat of terrorismâ⬠(p.181). Increase of terror alerts results to escalation of reduction of Baseball fans attendance. Kalist reckons that ââ¬Å"during the early days of the nations first-ever increase in the terror-alert level (i.e., rose from yellow to orange) attendance decreased by as much as 12%. A back-of-the-envelope calculation suggests that a team may have lost more than a half million dollars in attendance revenueâ⬠(2010, p.181). However, this suggestion faces incredible opposition since the most recent terror alerts has not been positively reflected into a reduction of fans attendance. The researchers of study conducted it in a time perhaps when people were not used to terror attacks threats by the ministry of state security. This is largely because most of the terror attacks threats hardly success. Terror attacks threats that do not materialize. They make the public to lose confidence for governmentââ¬â¢s announcements of likelihoods of terror attacks. However, sporting facilities remain outstanding targets for terror attacks perhaps due to high anticipations of a large crowd turnout. In fact, ââ¬Å"he Federal Bureau of Investigation (FBI) has made repeated statements about terrorist interest in stadiumsâ⬠(Kalist, 2010, 189). Convenience and security are perhaps two factors that fans establish tradeoffs. Inadequate security has the capacity to annoy the fans to the level that they may choose never to attend again in the future. This is argument is perhaps more significant and applicable to people who have encountered insecurity instances at one or more attendances. Fears of terrorism have additionally resulted in the increment of insurance costs. For economic reasons, the owners of the stadiums have to extend this cost to the fans in terms of increased tickets, prices. Feeling of insecuri ty fueled by fears of terror attacks affects major and minor baseball leagues attendance negatively both in terms of increase in ticket prices and the need to refrain from places that one is likely to be afflicted by aftermaths of the terror attacks. International players The United States does not dispute the incorporation of foreign players into the Baseball teams. It is widely acceptable among sporting scholars that fans initially attended tournaments to celebrate the achievements of people they regarded as ââ¬Ëtheir ownââ¬â¢. Does the incorporation of foreign players in the baseball team affect the attendance of the fans? Tainsky and Winfree (2010) demonstrated ââ¬Å"how traditional studies of consumerââ¬â¢s discrimination can be applied to gauge the impacts of international players in sportsâ⬠(p.126). According to Tainsky and Winfree, the incorporation of a foreign player not only resulted to discrimination amongst the MLB teams players but also affected the tea mââ¬â¢s quality. However, ââ¬Å"the net effect of additional international player has evolved with time from negative to positiveâ⬠(Tainsky and Winfree, 2010, p.126). More and more fans continue to develop the sense of internationalism. Hence, their attendance in response to incorporation of international players in major Baseball leagues also increases lineally. This is, in fact, immensely vital since as Tainsky and Winfree (2010) reckon, ââ¬Å"MLB, have actively tried to become more international by signing international players or scheduling more games outside the United Statesâ⬠(127). Perhaps also with appreciation of the need to incorporate the international players in the MLB teams, MLB deploys incredible endeavors to advertize base ball tournaments in other languages apart from English. As Tainsky and Winfree (2010) argue ââ¬Å"â⬠¦domestic demand is not affected by international playersâ⬠(p.127). Opposed to long gone perceptions, global perceptions have resulted to immense alteration of fans regards about international players in the MLB. Furthermore, Tainsky and Winfree (2010) indicate, ââ¬Å"The largest negative change in revenue from an international player came in 1985 with a loss of $731,875. In 2000 when the effect peaked teams increased their revenue by $595,632 from an international playerâ⬠¦Ã¢â¬ (p.127). Based on peopleââ¬â¢s arguments, increased arise from increased attendance. Location of the major league Location influences the attendance of fans in the Baseball tournaments especially the major leagues. Location is significant since it influences other factors such the capacity of the fans to commute. The influence of location to attendance of major Baseball league concerned Winfree, Mittelhammer and Fort who conducted a ââ¬Å" travel-cost model to analyze the attendance impacts on major league baseball (MLB) of the closest substitute MLB teamâ⬠(2004, p.2117). Majority of the Baseball leagues own ers complains of the probabilities of experiencing uncertainties in terms of finance in future attributable to imbalances of competition problems. As part of the solution to these problems, people have stood an excellent chance ofà making many proposals. One of them is that ââ¬Å"MLB should allow owners to move their teams, especially to larger markets to reduce the imbalanceâ⬠(Winfree, Mittelhammer Fort, 2004, p.2117). One question surface: Does change of location by virtues of relocating a major Baseball facility to a market with more financial capacity help increasing attendance and hence the revenues to the owners of the facilities? Location carries within itself many other factors that might influence attendance such as the existence of other Baseball teams within the area that might acts as substitutes that would have the net effect of reducing the attendance of a certain MLB. Location is significant in the evaluation of factors that influence the attendance since tr avel cost entangles a cost that Baseball fans have to meet. Arguably, if location needs to be significant, then in case there are two facilities within an area that offers equal utilities amongst fans, then it is widely anticipated that the fans would choose to attend the tournament that is closest to them. In this context, it ââ¬Å"implies that attendance lost to a substitute team should be a functions of the distance to that other substituteâ⬠(Tainsky and Winfree, 2004, p.2118). Now, it is essential to ask ourselves how prominent location is in comparison to fans loyalty to their teams. From a different dimension, it is crucial to look at the location and its impacts to the attendance of Baseball leagues as a function of other factors that influence the same. Tainsky and Winfree, (2004) posits that ââ¬Å"The utility of a Baseball fan is a function of the number of visits to baseball stadiums, the quality of the teams, the quality of those stadiums, as well as all other goo ds consumedâ⬠(p.2118). It is thus worth to argue that, the dominant factor among all these factor wins in terms of contributing and controlling the fans decision to attend a given Baseball competition. Tainsky and Winfree finding claim, ââ¬Å"A travel cost model is used to explain attendance for MLB teams, 1963ââ¬â1998. At the sample average variable values, a one-mile increase in distance to a substitute MLB team increases attendance by about 1544 fansâ⬠(2004,p.2123). These results indicate that in case a substitute team emerges within the vicinity of an existing team, the attendance of the first team is likely to reduce. However, when this teams assume their market share of fans, ââ¬Å"ongoing attendance impacts are small, even when a team might be placed fairly close to anotherâ⬠(Tainsky and Winfree, 2004, p.2123). Bearing in mind the economic consequences change of the location can have on the fansââ¬â¢ attendance, change of location should encompass o ne of the things that owners of Baseball facilities needs to consider before attempting shift the location of their facilities. However, this does not disregard out the weight of other factors that may contribute towards pre-bargaining for the need of relocation. This is largely justifiable since a good number of fans can be willing to attend tournaments of Baseball teams to which they have developed incredible loyalty towards no matter the commuting costs. Ticket pricing Sport teams have three principal sources of income. These sources are ââ¬Å"sales, of media rights, concession sales and ticket salesâ⬠(Meehan, Nelson Richardson, 2007, p.572). As a way of ensuring that sport teams have maximized their profits, the teamââ¬â¢s owners need to be in possession of ample knowledge about the relationship, between the attendance and the pricing of the tickets. Pricing tickets at higher prices, from the most general dimension and given that the demand is inflexible, means increa sed revenues and hence profits. On the other hand, increased attendance, even without necessarily increasing ticket prices, means increased revenues. However, is it possible for demand to be inflexible even in the helm of increased ticket prices? As Meehan, Nelson and Richardson (2007, p.572) posit, ââ¬Å"A host of factors influences the demand for sports, including the price of tickets, fan income, the population of the drawing area, team quality, and the age of the stadiums in which teams playâ⬠. Each of these factors has different impacts on the attendance. For instance, Meehan, Nelson and Richardson (2007, p.574) claims that ââ¬Å"the sensitivity of attendance to changes in the price of tickets (the elasticity of demand) and to changes in average incomes (the income elasticity) may vary from team to teamâ⬠. Meehan, Nelson and Richardsonââ¬â¢s study investigated 23 MLB teams in 1970 to 2003. They deployed series data to make them be at a point to pin point on certa in factors that had a direct influence on the attendance of Baseball leagues. To this extent, ECM (error correction model) came in handy. The results of the study indicated that ticket pricing was amongst the factors that affected the attendance in the baseball league. Their results contend with other scholarly studies that ââ¬Å"MLB ticket prices are set in the inelastic range of demandâ⬠(Meehan, Nelson and Richardson 2007, p.577). Setting ticket prices in any elastic range of demand has the effect of reducing demand and hence revenues in case any adjustments are made on the ticket prices. This is perhaps necessary for the purposes of ensuring that ticket pricing does not result to dwindled demand. Reduced demand is a substantial impediment towards ensuring increment of baseball facilities profitability. Conclusion A number of factors affect the attendance of fans in both major and minor baseball leagues. These factors range from incidences of voicing likelihood of terror at tacks, team quality, top prospects, ticket pricing, and influence of international players, promotions and location of Baseball facilities. Before making any policy, the Baseball facilities owners, consequently, need to put all these factors into consideration since they affect the attendance of the fans differently. This goes hand in hand in determining the future financial position of the Baseball clubs. Reference List Butler, M. (2002).

Three advantages of having globalization in Islamic Societies Term Paper
Three advantages of having globalization in Islamic Societies - Term Paper Example Globalization's flourishing of education has numerous advantages to Islamic Societies. First is the benefit of education that will not only make Muslims educated but will also enable them to fulfill their duties of attaining education (IslamiCentre 1). Through globalization, education will also become accessible to everybody and this will include the poor who would hugely benefit from a universal education because it would become affordable (if not free) and accessible to them (YaleInsights 1). Education will suddenly be transformed from being only available to the few and the elite to the general masses of Muslim. Globalization will also become education cheaper and thereby, affordable for almost every Muslim. The Muslims who never saw a classroom or a teacher can now be reached through globalization's global village that the day will come that every Muslim will become educated making Islamic society the center of learning again. Globalizationââ¬â¢s advantage will also help propa gate the proper teachings of Islam. Its scholars would be able to reach more Muslims and this would result to more educated Muslims understanding the Quran and in the process helping them to become better Muslims and better persons. The proper teaching of Islam will also prevent its misuse where evil deeds are committed its name. Through the proper teaching of Islam, the extremists can no longer justify their acts because Muslims will find it unacceptable having understood the Quran well for they are properly educated. In the same manner, the West can no longer blame Islam for its terror because it will understand that Islam is never a religion of conflict and ignorance but a rather religion of peace and learning. A globalized environment will also increase the cooperation and collaboration between Islamic nations and it can lead to economic success in different Islamic countries. This can be done through increased trade, mutual protection and greater cooperation. Thus, poverty in t he Muslim world will cease and Islam can no longer be blamed for poverty. This will strengthen Islamic societies because when they are no longer poor, they will have more time and energy for study and self-development. In the process it will make Muslims closer to one another and in so doing, strengthens the bond between them making them brothers and sisters in Islam. This bond brought by globalization can address the common issue of Islam's fragmentation that Shininy stated in his study that there is lack of unity between various Arab nations. With globalization, there will be more opportunities for Muslims around the world to interact thereby making Muslims united again. In addition, globalization will make the mobility of people faster and this will help Muslims visit each other to foster unity. This unity can also counter the influence of the Western world and preserve the culture and tradition of Islam which had been assailed since (Shibiny X). In addition to the preservation o f Islamic culture and tradition from the influence of the West, globalization's trade can also lead to the strengthening of the ties of different nations in the Islamic world

Conflict as a Team Tool-Terence Essay Example | Topics and Well Written Essays - 1500 words
Conflict as a Team Tool-Terence - Essay Example Task interdependence can be referred to as where actions by one team in an organization or under project influences the outcome of other members. To this extent, all team members must collaborate and work together for the benefit of the organization. Management must decide on the level of acceptance that can be allowed between teams if they are to achieve a better result. The following outlined discussions can be used to illustrate the degree of interdependence between groups in an organization. Task independence in most of the organizations is the link between the team commitments and team performance. In situations where the independence levels are high, teams will work together and contribute interactively to achieving the goals and objectives of the organization. On the contrary, where moderate task independence exists, team members are most likely work discretely for the accomplishment of their target (Fransen, Kirschner & Erkens, 2011). The connection between goal commitment and performance will only occur if the level of interdependence is high. It is because team commitment influences the outcome since the results are due to the collective responsibility of the entire members. The impacts that are then generated on performance are greater on the performance than if the interdependence levels were low. Due to the relationship between team goal commitment and team performance, interdependence between teams should be allowed to a greater extent as both members require one another (Halevy, Chou & Galinsky, 2011). Where the goal commitments do not relate to the performance, team members can concentrate on individual outcomes than a collective responsibility and team independence will be low. Assume two IT firms in apple and dell with both aspiring to be market leaders in technology sectors. The two organizations will become

The Gear Reduction Starter Engineering Essay
The Gear Reduction Starter Engineering Essay A starter motor is a high-torque motor for tuning the gear on the engine flywheel. Starter motor is also known as starting motor or a starter. The function of starter is to reduce the starting current by inititlly high resistance. In RLC series circuit resistance, inductance and capacitance are connected in series. Starter is used to protect the motor from overload. If the starter is 3ph to avoid single phasing and it is used to reduce the strating current. In motor starter both Otto cycle and Diesel cycle internal-combustion engine require the pistons to be moving before the ignition phase of cycle. This means that the engine must be set in motion by an external force before it can power itself. A hard crank was used to start engines, but it was inconvenient, difficult, and dangerous to start an engine. Care had to be taken to retard the spark in order to prevent backfiring with advance spark setting. The engine could kick back, pulling the crank with it, because the overrun safety mechanism works in one direction only. In this case users were advised to cup their fingers under the crank and pull up, it felt neutral for operators to grasp the handle with the fingers on one side, the thumb on the order. Even a simple backfire can break thumb or it is also seen that it could end with a broken wrist. The electric starter ensured that anyone could easily start and run an internal combustion engine car, and this made it the design of choice for the car buyers. ELECTRIC STARTER The electric starter is a permanent-magnet or a series parallel wound direct current electric motor with a solenoid switch mounted on it. Current from the starting battery is applied to the solenoid through a key operated switch which pushes out the drive pinion on the starter drive shaft. The solenoid also closes high current contacts for the starter motor, which begins to turn. Once the engine starts, the key operated switch is opened, a spring in the solenoid assembly pulls the pinion gear away from the ring gear and the starter motor stops. The starterà ¢Ã¢â ¬Ã¢â ¢s pinion is clutched to its drive shift through an overrunning sparg clutch which permits the engine to transmit drive only in one direction. This is why the drive is transmitted through the pinion to the flywheel ring gear , but if the pinion remains engaged, the pinion will spin independently of its driveshift. This prevents the engine driving the starter for such backdrive would cause the starter to spin so fast as to fly apart. That is why a standard starter motor is only designed for intermittent use which would preclude its use as a generator. This system of pinion arrangement was used in early 1960à ¢Ã¢â ¬Ã¢â ¢s after that a new system was introduced and named as Bendix Drive. The Bendix system places the starter drive pinion on a driveshift. When the starter motor starts turning, the inertia of the drive pinion causes it to ride forward and thus engage with the ring gear. When the engine starts, backdrive from the ring drive causes the ring gear to exceed pinion to rotative speed of a starter, at which point the drive pinion is forced back down the helical shaft and thus out of mesh with the ring gear. The drive unit is spun at a releasing the latch and permitting the overdriven drive unit to be spun of engagement. In this matter unwanted starter disengagement is avoided before a successful engine start. GEAR-REDUCTION STARTERS In 1962, Chrysler introduced a starter incorporating a geartrian between the motor and the driveshaft. Rolls Royce had introduced a conceptually similar starter in 1964 but Chrysler was the first to bring volume-production unit in the market. The motor shaft was integrally cut gear teeth forming a drive gear which mesh with a larger adjacent driven gear to provide a gear reduction. This permits the use of higher speed, lower current and lighter motor assembly while increasing cranking torque. The Chrysler starter made a unique, readily identifiable sound when cranking the engine. This starter formed the design basis for the offset gear reduction starters now employed by the vehicles on the road. Light aircraft engines also made extensive use of this kind of starter because of its light weight that offered an advantage to the aircraft companies. Ford also issued a nonstandard starter, a direct drive à ¢Ã¢â ¬Ã moveable pole shoe à ¢Ã¢â ¬Ã design that provided cost reduction rather than electrical benefits. This type of solenoid eliminated the starter. There are some steps that we have to follow while operating the ford starter:- The operator closed the key-operated starting switch. A small electric current flowed through the starter relay cord , closing the contacts and sending a large current to the starter motor assembly. One of the pole shoes hinged in the front, swang into position. This moved a pinion gear to engage the flywheel ring gear. The starter motor cranked the engine until it started. The operator released the key-operated starting switch, cutting power to the starter motor assembly. A spring retracted the pole shoe and with it the pinion gear. This starter was used on ford vehicles from 1973 through 1990, when a gear reduction unit conceptually similar to Chrysler unit replaced it. PNEUMATIC STARTER Some gas turbine engines and Diesel engines ues a pneumatic self starter. The system consists of geared turbines , an air compressor and a pressure tank. Compressed air released from the tank is used to spin the turbine, and through a set of reduction gears, engages the ring gear on the flywheel, much like an electric engine. On larger diesel engines found in large shore installations and especially on ships, a pneumatic starting gear is used. Theair motor is generally powered by compressed air. The air motor is made up of center drum about the size of a soup can with more than four slots cut into it which allows the vanes to placed radically on the drum to form chambers sround the drum. The drum is offset inside a ring casing so that the inlet airfor starting is admitted at the area where the drum and the vanes form a small chamber compared to others. Some small diesel engines such as ones found on tugboat and lifeboat use hydraulic starters in which the air is replaced with a hydraulic motor. The engine should not be shut down while running unless the hydraulic accumulators for the starting motor are recharged. Else there is a manual hand pump to slowly pump up the accumulators. On large diesel engines and almost all diesel generators used the prime movers of the ships will use compressed air acting directly on the cylinder head. This is not ideal for the small diesel engines as it provides too much cooling on starting. The actual compressed air is provided form a large reservoir that feeds into a header located along the engine. As soon as the air starts the valve starts opening and the compressed air is admitted and the engine will being turning as it can be used on 2-cycle or 4-cycle engines and on reversing engines. On large 2-stroke engines less than one revolution of the crank shaft is needed for starting. This is why the heavy trucks use air breaks and the system gives the double duty by supplying compressed air to the break system. Pneumatic starters have the advantage of delivering high torque. ELECTRIC MOTOR The electric motor converts electric energy into mechanical energy. Electric motor operates through interacting magnetic fields and current carrying conductors to generate force. Electric motors are found in applications as diverse as industrial fans, blowers and pumps. They may be powered by electric current or by alternating current from a central electrical distribution grid. The smallest motor is found in electric wrist watches. Medium size motor of highly standardized dimensions and characteristics provide convenient mechanical power for industrial uses. The very largest electric motors are used for propulsion of large ships. The physical principle of production of mechanical force by the interaction of an electric current and a magnetic field was known as early as 1821. Electric motors of increasing efficiency were constructed throughout the 19th century, but commercial exploitation of electric motors on a large scale required efficient electric generators and electrical distribution networks. Device used with AC electric motor to temporarily reduce the load and the torque in the powertrain of the motor during start is known as electric motor. Mechanical stress is also reduced by the electric motor. INDUCTION MOTOR There are different types of asynchronous AC motors and one of them is induction motor. When power is supplied to the rotating device by the means of electromagnetic induction. There are several ways to supply power to the rotor. In a Dc motor this power is supplied to the armature directly from a DC source. Sometimes an induction motor is also called a rotating transformer. This is because the stator is essentially the primarily side of the transformer. TYPES OF STARTER MOTOR Direct on-line starter Star delta starter Automatic star delta starter Auto transformer starter Steps starter Motor soft starter Differences in some of starter motor are as follows 1. Difference between Direct on-line starter and Star delta starter A direct on-line(DOL) starter connects the motor terminal directly to the power supply. Hence, the motor is subjected to the full voltage of power supply. Consequently high starting current flows through the motor. This type of starting is suitable for small motors below 3.75kw. reduced voltage starters are employed with motors above 3.75kw. Although DOL motor starters are available for motors less than kV. Supply reliability and reserve power generation dictates the use of reduced voltage or not. 2. Differences between Star delta starter and Automatic star delta starter To reduce the starting current of an induction motor the voltage across the motor needs to be reduced. This can be done by autotransformer starter, star-delta starter or resistor starter. These days VVVF used extensively for speed control serves this purpose also. Whenever you start a big heavy electric motor, you need to start it slowly to prevent the rotor overheating and drowning an enormous current. Future prospective Methods are changed in building the starter motor. Many new technologies continue to be introduced in new cars and trucks. General improved methods are:- better engine peak efficiency potential losses are reduced at light load from throttling weight, drag and rolling resistance is also reduced Mid-term engine technology is introduced on the market. Most promising development is cam-less valve actuation which offers potential to reduce throttling loss to near zero. New technologies introduced in the market are quite expensive but are very beneficial for the ecological balance.
