...What is interesting about those three aspects is that you have to have all three of them in order to have the others. One cannot learn a truly valuable lesson without a previous fault; therefore you cannot achieve and accomplish goals without the knowledge gained from the lessons learned. Learning lessons and values is the key to understanding who you are, and what you are going to do. Yes, learning is great, but it is what you do with that knowledge that in fact defines the person. The lessons I learned from this event are always with me, they have made an indescribable impact in the person I have to grown to be today. This is the incident that changed my life and gave me the greatest wakeup call I have ever known. BMW manufactured a sport crossover called the X5. The X5 has a powerful engine and has remarkable handling. My father had always driven SUVs’ and wanted to try something new so he acquired a 2008 BMW X5. On this spring night I decided to try out the speed of the car. There is a street called West Parkway, which is approximately three quarters of a mile. This street is long and straight, perfect for speed. My friend and I had made three passes down the street earlier in the evening, reaching speeds of 110mph. We decided to make one more pass, which would be our last. Unfortunately we had not noticed the slight mist that had accumulated on the road. The car is floured, 80, 90, 100, 110, finally 120mph! Ok, time to slow down. As I pressed the brake pedal I noticed that...

...less boxy cars, but also extremely fuel-efficient cars such as the BMW x5, Cadillac has discovered that many people prefer to go with more features that are representative of the 21st century consumers. Many Cadillac buyers are realizing that Cadillac as a brand does not compare to the edgy brands such as BMW and Mercedes, and the brand perception of Cadillac represents elder drivers, which has hurt their bottom line, especially since the tastes and preferences of buyers have changed. To counter this major criticism that Cadillac has received, they have done two things; redesign existing models to make them more visually appeasing, and develop fuel-efficient cars. For example, Cadillac introduced the Cadillac ATS coupe, trends BMW sports car have adopted that represent a sleek, and trendy feel. Cadillac introduced the ATS coupe as a way to compete with not only BMW aesthetically, but change consumers image of Cadillac. Secondly, Cadillac introduced the Cadillac SRX to compete directly with the small SUV market, but also offer a relatively fuel-efficient model that will please many consumers. I would consider all the actions that Cadillac is taking to be both reactive and proactive, as they are reacting to the market effectively to make sure that there is still a market share for Cadillac cars in the future, however they are proactively making sure that there is still a chance for success later. It is not...

Node B: v=+∞ (since B is min) then it traverses to Node E where(α,β)=( -∞ , +∞ ). Node E: v=-∞ (since E is max) then it traverses to leaf Node L where(α,β)=( 7 , +∞ ) (since 7 is better than -∞) leaf Node M where(α,β)=( 7 , +∞ ) (since 7 is better than 6) so at Node E: v=7 In the already explored path at Node B: v=7 where(α,β)=( -∞ , +∞ ) Node F: v=+∞ then it traverses to Leaf Node N where(α,β)=( 8 , +∞ ) (since 8 is better than 7) Here the maximizer compares the value with other alpha values.

...English1 11/23/2015 Sports Are Beneficial Have you ever thought about why people do sports? Many people fail to find good reason. Exercise and physical activity is a very important factor in today’s world. Because of the benefits that are possible from sports involvement society needs to encourage involvement more. Children and young adults that participate in sports like activities tend to develop good habits that they continue to use into adulthood. Many people feel that sports are not beneficial and fail to become engaged. Sports involvement not only helps build healthier lifestyles but also allows people to become socially active and occasionally provide added incentives to educational costs and careers. Despite some people believing that sports participation carries negative effects as well I believe the good outweighs the bad. With more than a third of the adults in the USA being classified ad obese, many overweight it is important for more people to become involve in sports. People that do sports on a regular basis burn more calories than those that don’t. Those people that are involve are less likely to end up overweight. It has been noted that exercise and sports activities help decrease heart disease, strokes, manage high blood pressure, diabetes and a range of other conditions. Many people fail to realize that also that sports involvement allows those that eat healthy extra calorie allowance so they won’t feel guilty. “Sports can help improve mental and...

...While sport activities-and physical activities in general-are beneficial behaviors for physical and mental development, I believe that sport activities should not play a very important role in middle-schools and high schools as they currently do. I agree to those who believe that sport activities within schools should not be valued to the extent to which they are at the moment because the existence of many such activities makes many children and teenagers to have their priorities orientated toward sport performance and not toward academic performance. As it is argued in Amanda Ripley's article “School Should Be About Learning, Not Sports”, since many sport activities from high school receive more media coverage than any academic-oriented activity,...

...Impact of Extracurricular Activity On Students Mitchell Sable University of Detroit Mercy Extracurricular activities are any activities that students participate in outside of the mandatory educational curriculum. Students can participate in extracurricular activities at any age. These activities can be affiliated with the school or be outside of school. Extracurricular activities may include sports teams, special-interest clubs, theater, music, art, work, and volunteering in community service fields. Extracurricular activities are an important topic in today’s society due to colleges and graduate programs looking for ever increasing involvement of students outside of classes. It is important to know how participating in extracurricular activities can increase overall success for individuals. It is also important to discuss if the cost of extracurricular activities are worth the consequences they bring or if the money would be better spent on direct learning. This research paper will focus on students in middle school and high school, and the articles chosen are able to show how extracurricular activities correlate to grades, motivation, and overall success of the student. The article Extracurricular Participation and Academic Outcomes: Testing the Over-Scheduling Hypothesis by Jennifer Fredricks (2011) showed that 10th graders with extracurricular activities exhibited positive effects from them. Students received the greatest improvement in grades from zero to five hours...

Youth sports help kids make good life decisions and can also help with social skills, helping them later in later future events. Britt Hallingberg, a scientist at Cardiff University, claimed, “Many youth people benefit from participating in fun, structured activities out of school.” This claim shows that sports can be healthy for you and your social life in and out of school.

...interests living in a particular area. A community is also a local grouping within which people carry out a full round of life activities. Although families or other groups can sometimes be relatively self-sufficient, most of them do not live in isolation. For many reasons, ranging from economic interdependence to shared cultural values, families and other groups normally join together to form communities. The community, rather than the family, becomes the social setting for most everyday economic, political, religious, educational, recreational and similar activities. As communities become larger and more complex, other types of organizations are often established within the community to perform these various functions. Thus, a community is a type of social organization that is territorially located and provides the setting for dealing with most of the needs and problems of daily living. Communities vary widely in size and complexity. Recreation McLean and Hurd., (2011) defines recreation as a network of public agencies that provide such facilities as parks, playgrounds, aquatic centers, sports fields, and community centers in thousand of cities, towns, and countries. Recreation is also defined as any activity performed during one’s leisure or free time. Recreation is very essential element of human biology and psychology. Recreational activities are often done for enjoyment, amusement or pleasure and are considered to be “fun”. Recreation implies participation to be...
