Managing Performance in Turbulent Times Research Paper

Managing Performance in Turbulent Times - Research Paper Example This paper examines how Google competes in the world of the internet and e-commerce. It examines the various points which Google uses to gain an advantage of its competitors and remain at the top of the industry. Barrows & Nechy (2011 p85) identify that the brain behind the success of Google lies in its ability to innovate. As compared to its competitors, Google spends more time and effort to identify new communication systems and methods at different points in time. Although Google started as a search engine company, it spent time and money to research and identify the true needs and desires of customers. In 2005, they launched personal email services which they believed was in demand by the markets. â€Å"They pursue a strategy that aims at increasing the capacity of computers and communication† (Png & Lehman, 2007 p3). This means that research and development are a fundamental part of Google. They put in more effort to find out what consumers need at every point in time and work to provide that specific service according to the highest standards and expectations possible. Google, therefore, sets out to organize the world's information rather than just make a profit for the sake of getting money from the consumers (Carter et al, 2011 p147). They, therefore, try to find ways of satisfying consumer needs at specific times. Google, therefore, has competitors not only in the normal internet companies but also, traditional publishers and other outlets. Google is aware that it operates in one of the most turbulent industries in the world. They, therefore, appreciate the fact that consumer needs change at a regular interval. Google, therefore, changes regularly to meet these demands. On the average, Google makes major changes to its strategy each month (Carter et al, 2011 p148). The internal structures of Google support its vision of leading in innovation. Googles workers are grouped in teams  of 20 – 50 employees under a single manager.

Try to apply keneth waltz's three images to the orgins of the Article

Try to apply keneth waltz's three images to the orgins of the cold war and analyize which image considerations were more important in the development of the cold war - Article Example In the second image, Waltz posits that wars are mainly caused by the domestic ambitions of the states (Waltz 45). He employed the Lenin theory of imperialism to explain that capitalists are driven by their ambitions to create new frontiers in other places to increase their domestic economic power. Separates states structures influence war. This is why Waltz argued that multipolar systems had a higher likelihood of war conflicts that bipolar systems. The third image, one that he put great emphasis, is a fine tuning of the structural realism that he had devised (Waltz 56). The anarchic structure of the international system is a huge influence of the international relations. The structure of the international power is dependent on frequency and size of power fluctuations, offense-defense balance, size of first-move advantages and the amount of resources. Arguably, the cold war was about the balance of power. Kenneth Waltz third image shows more concern to the dynamics of the anarchic nature of the international system (Suganami 384). The standoff between the United States of American and the Soviet Union during the cold war depicts a scenario where the two major powers were exhibiting interests in third parties. On this note, Waltz argues that bipolarity stands to lessen a conflict such as that of the cold war because the countries would go back to relying on their resources instead of competing for those of the third parties to try and bring a balance of power. This third image shows an in-depth focus on the bigger perspective of the cause of war by showcasing the underlying causes rather than only highlighting the superficial causes such as the human nature in the first image and the domestic influence of the second image. This implies that the third image is more refined to show how the players of the cold war envisioned the mann er to influence the balance

Removing Hurdles of Management Case Study Example | Topics and Well Written Essays - 1000 words

Removing Hurdles of Management - Case Study Example The first understanding that must be referenced has to do with the need for effective management techniques that can provide for a culture of success within the new expansion. Whereas the provision of certain products to the consumer is ultimately the means by which the company could hope to become successful, the establishment of an effective culture within the company, and exhibited amongst its employees, will also have a tangential and direct effect on whether or not consumers will be satisfied with the products and will seek to repeat the buying experience in the future (Gorden, 2009). Likewise, management should seek to promote a level of unified and uniform training of its employee base so that they will be capable and knowledgeable with respect to understanding unique nonverbal cues that the consumers might provide them (Mollins, 2008). For instance, Shaun Gallagher would promote interaction theory as a means of developing a level of social and psychological understanding in t erms of the way in which the consumer react and the means by which the salesperson or staff member engages with that. Rather than merely providing employees with a certain set of expected statements or product promotion that they can provide, interactional theory would encourage management to place a specific focus on the level and extent to which money is directed towards training sales numbers in terms of how they should respond from a nonverbal point of view (Marpin, 2013). Â  Likewise, in attempting to craft an effective firm, Burn’s theory of leadership as such, would indicate that stakeholders within management should either practice a transactional form of leadership or a transformational leadership (Oppenheimer, 2013). As such, the transactional form of leadership is one in which the leader focuses on building relationships between the leaders and followers.

Media studies coursework Essay Example for Free

Media studies coursework Essay This is a tabloid newspaper that has been designed for a certain variety of readers. It is a light hearted, easy to read institute that thrives on sex and scandal. Although the paper can be quite serious, for example where there are political issues to be discussed, they are constantly using humour in the paper to get the reader more involved with what they are reading. The chosen institute is the Daily Mirror a rival of many other tabloid papers like the Sun newspaper. The paper is dated Monday March 17 2003 and priced at 25 pence. The main news events are Michael Jacksons interview with Martin Bashir and the fact that there may not only be one Saddam Hussein on this earth. These stories are newsworthy because the war is currently in the public eye; also the public want to know about celebrities as it refers to scandal on the front page. The main focus on this particular front page is the interview that took place between Michael Jackson and Martin Bashir; it draws your attention straight away as there is a very strong coloured image that is bigger than anything else on the page. This story also gets the lead story headline that the reader is drawn to straight away as the font is black on a white background making it stand out. It is also in block capitals making it easy and clear to read. The coloured image of Jackson and Bashir has been given a third of the page but the whole story has been given over half the page. The headline that reads Split of truth works very well with the still image. The image that has been chosen is very strong because it shows that Bashir has been welcomed into Jackson house like a friend and he has gone and betrayed him. To the reader this is scandal, and then even better there is a very well known celebrity involved. There is also a side headline advertising that if you want the full story of what happened during the interview, there are another four pages that have been dedicated to the story. Over the black background, in white it says Bashir betrays Jacko the reader will want to know how exactly Jackson has been betrayed. This is the main point of this news event that Michael Jackson has been betrayed. This particular story is taking Jacksons point of view in consideration, and is taking the opportunity to only express one view. The interview of Michaels former wife has been used on the front page as this makes the report more believable; when the quote from his former wife was used on the front page it was not finished as this will make the reader want to buy the paper in order to read on. The secondary lead is the one concerning that there may be more than one Saddam Hussein. It has been dedicated about a quarter of the page. Lots of coloured images of Saddam Hussein have been used; making it go very well with the headline title Spot the difference this has been written in white in a stencilled army font. Then it has been placed over a dark background making it clear. The secondary headline is relatively small being careful not to take the attention away from the lead story. Below the headline it say Special report! this suggests to the reader that only this institute has the answers you are looking for and it is special because nobody else has it. Coming of the left hand bottom corner is a magnifier with a brief explanation of what the story is about. The main point of the article is that there is more than one Saddam Hussein, and the angle that is being taken is that the truth will be revealed. The small explanation is very short but suggests that lots of research has been done on the matter, making the evidence believable. The language used for the lead story is very informal as this reading material is for a wide variety of people. The headline Split of truth is almost a play of words to go with the split image, giving the story a less serious side. In this particular story, it has taken a biased angle of siding with Michael Jackson, you can detect this from the way in which the side headline says Bashir betrays Jacko although the paper has taken Jacksons point of view they still dont let the seriousness of the event overcome the story completely so they still refer to Jackson as Jacko a name that has been given to him originally from the media. The language used for the secondary lead is also informal, using words to play with there images like Spot the difference something that the naked eye cannot do, so they are trying to convince the reader that they have the evidence to prove what some say to be right, this almost show a biased angle suggesting that what they are saying is the truth. Humour has been used in both stories with the way it refers to Michael as Jacko and the way in which the secondary story has been set out. It has been used as this get the reader more involved with what they are reading, it is also more likely that it will stick in their head and they will tell others what they have read. The sentence length used for the headlines is short and snappy allowing the reader to remember what they have read. The paper is edited to welcome an audience of different race, class, gender, sexuality and religion. You can see this from any of the stories, nothing has been pointed at any of these issues, nor are there any innuendos that have been made to any of these aspects. The editors have to be careful not to offend anybody in this manor as many of there own readers are of different sex, class, religion etc. It is also open to reader of all ages as they include stars like Jackson who are loved by children all across the glob and the language is in a gossipy form making it easy to read and more fun. The audience are free to make any points they wish to, this is one reason why I believe it is good that the stories are bias, so the tabloid are able to make a reaction something which they would not be able to achieve if both sides of the argument were given. When the audience are reading this they are able to read it in an active way as only one side of the story has been expressed. The front page is set out in a very clear way making it easy for the reader to pick up on something if they disagree with it. The use of colour and catchy headline make the paper appear to be very attractive. On this front page Michael Jackson has been represented in a positive way, giving him a chance to tell his story of what happened. The overall view of the front page is that of the good features that are its focus, which dont just concentrate on one particular story but each one has a good point about it whether it be a catchy headline, attractive colour picture like the one of Michael Jackson and Martin Bashir that gives a strong image to the story or the use of humour, not only used in the main story but used in the second lead to. Excellent use of phases like special report definitely imparts the reader towards the news. The only bad point about this front page was for the secondary lead there could have been some use of quotation for the reader to see, although I think that the image that has been used is enough to make a reader pick up this particular tabloid paper. I believe that this front cover is successful in its target audience because there is something for everyone, it just depends on whether the reader would like to read something light hearted or a bit more serious.

Relationship Between Sport Participation And Academic Achievement Psychology Essay

Relationship Between Sport Participation And Academic Achievement Psychology Essay Introduction This research is to identify if there any relationship between sport participation and academic achievement. In additions from thus study also it will show whether sport participation among student may affect their academic or not. The review of literature for this investigation focuses on three primary areas of concern. The research questions are: Is there any difference in academic performance between students who are participate in sport and student who are not participate in sport. Is there any difference in term of academic performance between male and female students athletes. To examine what are the benefits that students athletes get by participating in sport The first area represents the differences of academic performances between student who are participate in sport and student who are not participate in sport, which researcher want to investigate. The second part is to represent is focusing on the differences in academic performance between genders and as well toward on the benefit of participated in sport for academic achievement. Comparison between student that participated in sport and student not participated in sport. As we know, nowadays, a lot of student that involve in sport often make them hard to maintain their result but they can score during the examination (Shuman Michael, 2009). Besides, a lot of student success in their academic are usually active in sport, it will show if there are any differences between student that participated in sport and student that not participated in sport in their academic achievement (Shuman Michael, 2009). One of the first organizations who are concern to the question of the academic performance of student-athletes was the Carnegie Foundation. In its Twenty-Second Annual Report, published in 1927, the commission gave a detailed review of studies that had been complete about the relationship of athletics to scholastic attainment ( Twenty-Second Annual Report, 1927). According to sport participation and academic performance; proof from the National Longitudinal Study of Adolescent Health (2002) gives positive association between sports participation and academic performance. Besides that, based on Eccles, Barber, Stone, Hunt (2003), studies show that participation in athletic activities is to encourage a wide range of social, physical, and intellectual skills, which leading better in classroom performance. In fact there is fair quantity of proof to support this claim. As noted above, high school athletes on average perform better academically than non-athletes Solt, D.F. (1986). Moreover, Hindma has found that in the Colleges of Arts, Engineering, and Agriculture, the quarter grade point averages for athletes were higher. The average grade point average for non-athletes was 2.153 and 2.168 for athletes. In following these same students through the next four years, Hindman found that the degree attainment for athletes was better in every college and in total 37.2 percent of the athletes attained degrees compared to only 21.5 percent of non-athletes. Other than that, Eaton and Smith (1941) used the percentile grade ratings made on the American Council on Education Psychological Examination as an indication of aptitude and compared this with grade point average as an indication of achievement. Athletes were higher than compared with non-athletes. As been stated above, indicated that students who were involved in sport perform better in academic than those who were not. Besides, there are also possibility that those students who are involved in more sport are generally motivated than those who do not participate in sport. Furthermore, the majority of studies from the past, show those students involved in sport excel in the classroom. This also can be agreed by Ballantine (1981) showed that there is a positive connection between academic achievement and sport participation. Study by the U.S Department of Education (1997) revealed that students who participate in sport are three times more probable to have a grade point average or better (Mihoces, 1996). From this research show that student involve in sport are higher in the academic achievement than student that not participate in sport. Moreover, some previous research states that overall, student athletes graduate at higher rates than students in the general population. The most new graduation rates of 60% compared to 58% for the non-athlete population (Division I Athlete Graduation Rates, 2002). Differences in academic performance in athletes gender Refer to the past research carry out by Roger Whitley performed a study of North Carolina high school students stated that female athletes higher score in academic result. The students were divide into two groups, They were categorized as higher participant or low participant of sport according to the following rule. A student whose number of years in high school is better than their number of seasons participating in sport categorized as low participant (Stegman, 2000). A student whose number of seasons participating in sport is identical to or greater than their number of years in high school is categorized as high participants. This having a student who tried a sport or two as a freshman placed into the athlete category (Stegman, 2000). According from the past research state as below: Based on that, Mark Stegman says, I feel confident arguing that athletic participation does not hurt academic performance and it instills desirable qualities such as physical fitness, goal setting, teamwork, and self-discipline that help in all areas of students lives (Stegman 2000). The impact of sport participation on girls academic orientation was the focus of the number of studies. Feltz and Weiss (1984) found that socioeconomic level and extent of activity involvement were reason contributing to most of the differences between group, in which higher SES levels and higher levels of involvement were analytical of higher ACT scores. SES levels and extent of extracurricular involvement were influential other than students participation categories on females academic achievement. In another study, Synder and Spreitzer (1977) analyzed survey data on participation in sports as related to educational expectations among high school girls. The researcher found a positive relationship between both types of extracurricular participation and educational expectations. This study been showed that , sport for these high school girls may appear to a good result of academic achievement. Based on African-American male students, and presented mixed findings. Sport participation seems to have a positive effects on their educational aspirations (Braddock, 1980, 1981, ; Hanks, 1979; Picou Huang, 1982; Wells Picou, 1980), self-esteem (Braddock,1980, 1981 ; Hanks, 1979), college conscription and graduation (Braddock 1981), competitive orientation (Wells Picou, 1980), and adult earnings (Picou, McCarter, Howell, 1985). For this group of students, sport participation had mixed effect on their grades (Braddock, 1981; Wells Picou, 1980). Based on their investigation indicated that sport participation for these student was positively related to their aspirations to register in college preparatory programs in high school. Moreover, Marsh (1993) concluded from his study that sport participation may have an effect on academic achievement in that the participation where increase motivation. Hawkins and Mulkey (2005) suggested that sport participation created aspirations for African- American males to seriously consider attending college and act more suitably in school. For black female high school athletes, the literature presents a different picture. With respect to their participation in sport activities, we see mixed findings on their educational aspirations ( Hanks, 1979; Picou Huang, 1982), on support to attend college from parents, teachers, and peers (Hanks, 1979; Well Picou, 1980). Besides, Reith (1989) were analyzed through a survey of a large sample of these studies. The Hispanic high school female students who participated in sports were found to be more likely to score well on achievement tests, to stay in high schools and continue their education in colleges than their non-athletic peers. Regression result reveal that both male and female student athletes academic success is to some extent contingent upon the specific nature of their interaction with faculty (Fejgin 1994). The finding also showed that male and female student athletes have minimal differences in their various forms of contact with faculty. The implications of these findings are discussed among student athletes, faculty and advisors in order to improve their roles in establishing meaningful relationships with female and male student athletes inside and outside the classroom (Comeaux, 2005). The benefit of participated in sport. There are a lot benefit by participated in sport which indicated that participation in sports increased students overall interest and commitment to schooling as well as their engagement in more student-teacher contact, more positive attitudes about schooling, more parent-school contact (Crain, 1981; Trent Braddock, 1992). Moreover, Slavin and Madden (1979) found that sports could facilitate positive racial or ethnic relations as well as positive inter-group attitudes and behaviors among school. Crain (1981) reported similar findings. Furthermore, benefit of participated in sport could provide extrinsic rewards to students and help them form social bonds and relationships within school, (Crain, 1981; Slavin Madden, 1979); Trend Braddock, (1992), Besides, sport participation could create intrinsic values for students, according to Kavussanu and Mc Auley (1995). Based on this study, if highly student participated in sport they were significantly more optimistic and experienced greater self-efficacy than those non-athletes (Crain, 1981; Slavin Madden, 1979; Trend Braddock, 1992). Moreover, sport may provide a physical benefit to the student athletes and they can also facilitate the development of lifetime skills such as interpersonal and time management skills by working with a team of peers and coachers and also properly balancing between school work and practice. A number of benefits can be reaped from participation sports. Seaton etal (1965), Durojaie (1976), and John and Campbell (2001) note that participation in sports, which enhances physical fitness, contributes to good health. According to Ekperigin and Uti (1982), physical activity leads to good body posture, that is a balanced development of the whole body, the strength and fitness of all muscles. Sports being a physical activity help students to cooperate and work with others under the same rules and regulations towards a common goal while commenting on re-introduction of sports in Afghanistan Ekperigin and Uti (1982).Arnoldy (2005) observes that sports can be used as a vehicle for creating a safe space and an entrance into the public sphere. Besides that, Clarke (1977) contended that sports should gradually lead to a sense of order and self-control which make student able to control their selves in school or in competition. Furthermore, according from previous research, Weinberg and Gould (1995) athletes have better personality than non-athletes. In their research, they found out that those who play team sports as compared to non-athletes exhibit less abstract reasoning, more extroversion, more independent and less ego strength while those who play individual sports as compared to non-athletes display higher levels of objectivity, more dependency, less anxiety and less abstract reasoning. But, still other researcher have noted that athletes are more independent, more objective and less anxious than non-athletes (Cox, 1998). This showed that being an athletes give more benefit than non-athletes. As been stated above, it showed that sport participation are a lot give benefit to the student that involved in sport. Sport makes them healthier, more independent, gives motivation to them during the class and their training by Seaton etal (1965), Durojaie (1976), and John and Campbell (2001). Besides, sport participation are also make the student more discipline, hard working ethics and more focus in class and in their training by Seaton etal (1965), Durojaie (1976), and John and Campbell (2001). Moreover, sport participation give a good personality of the student where the student will increase their self-confidence, develop positive attitude and able to think professionally by Seaton (1965), Durojaie (1976), and John and Campbell (2001).
