=About me = My name is Changning Dong and this is my wiki for the course ADM 2372. I am a first year student, majoring in Finance at the Telfer School of Management. I was born in Nanking, China. I came to Canada December 19, 2008. This is my second semester at the University of Ottawa. I am interested in soccer, so I would like to do my pages about soccer. Although in North America soccer is not as popular as in Europe, if you realize it, you will like it.

 Recovering from his growth deficiency problem, the Argentinean started playing regularly for FC Barcelona's youth squad and in a few years, he was taken to the B squad of Barcelona, where Lionel Messi's goals started placing the spotlight on him once again. Despite his small frame, he managed an impressive 35 goals in 30 matches and in 2004 he made his official debut for the senior squad of the Catalan team, in a local derby against Espanyol Barcelona. He was 17 years and 3 months old on his debut. He didn't play in a lot of other games in that season, but in May 2005, he managed to score his first official goal, against Albacete, becoming the youngest player to ever score a goal for Barcelona in a league game. Getting more and more match experience, he slowly earned a solid place in the first team and his pace, passing and goal scoring ability earned him standing ovations wherever he would play, especially a memorable one in a match against Udinese in the UEFA Champions League on Nou Camp, where Messi single-handedly won the match and made the stadium's capacity rise to their feet in a gesture of respect. From that moment, he was almost indispensable in Barca's first squad and although several thigh injuries kept him away from the pitch, he came back in force in the 2006-2007 season. Probably his most memorable match and the one that truly made him the big star that he is today was the El Clasico duel on March 10th 2007, where Barcelona met arch-rivals Real Madrid on Nou Camp. Messi managed to score a hat-trick, with his last goal being a crucial equalizer scored in the 90th minute. That Lionel Messi goal will live long in the memory of the Barca fans, as everyone talked for weeks about the 19-year-old kid that brought Real Madrid to its knees.

=The technology in soccer=

adidas and Cairos Technologies have unveiled a new Goal Line Technology and the adidas intelligent football at the FIFA Club World Cup in Japan which finishes this weekend. The official match ball of the tournament, adidas Teamgeist II, features a new technology designed to assist the referee’s decision in determining when and if the ball has crossed the goal line, making it the most accurate football ever produced. While it may seem an extravagant use of technology to determine accurately something which rarely comes into question (with one or two goals per team per side, and a net to catch the balls when they have crossed the goal-line, this technology will only make a difference once in every several hundred games), the entire Cairos system which supports this technology is capable of tracking the ball and all player movements in real time. Our money is on the full blown Cairos technology eventually being adopted at the elite level, partly because it would further human understanding of human physiology and the tactics of the complex game of soccer (player movements and condition can be tracked in real time), but mainly because the eye candy information graphics that can be generated from the goldmine of data - the power of television and its quest to add uniqueness to its coverage will spawn the adoption of the entire [|Cairos system]. “The purpose of the adidas intelligent ball and Goal Line Technology is to provide greater transparency during a match and to assist the referee in making quick decisions that can impact the outcome and quality of the game” said Hans-Peter Nuernberg, Senior Development Engineer, adidas Innovation Team. “We expect the system to perform very well during the FIFA Club World Cup™ in Japan and we will continue to refine the system so that it is 100% accurate.” The intelligent technology implemented in the Teamgeist II uses a magnetic field to provide real-time feedback to a central computer, which tracks the location of the ball on the field and sends the data directly to the referee. By using a magnetic field and more stabilized and robust components within the ball, the new system is more precise and is not influenced by in-game factors, adverse weather or nearby technical systems. “With the complexities and precision needed for Goal Line Technology, it is imperative that the system is tested in a variety of competitive in-game situations,” said Christian Holzer, COO of Cairos technologies. “The opportunity to test the new technology during such a competitive tournament will supply us with the valuable feedback needed in order to continue refining the system.” Since 2003, adidas and Cairos in cooperation with FIFA, have developed the Goal Line Technology, which was first publicly tested in 2005 during the U-17 FIFA World Cup™ in Peru. The first system used radio transmissions to correspond with a central computer and a microchip suspended in the ball to determine its location on the field. The new Goal Line Technology and adidas intelligent ball have been redeveloped since 2005 to address the critical situations in which better accuracy is needed. Following the testing during the FIFA Club World Cup™ in Japan, the results will be evaluated and next steps will be determined by Cairos technologies and adidas as to when the system will be ready to test again publicly. The new system currently meets all International Football Association Board (IFAB) requirements and the ball has been approved by FIFA for competitive international play.

=Reflection on wiki use= Wiki is very useful, which allows us to share our knowledge with others. As I only have been in Canada for half a year and my first language is not English, sometimes I could not understand some significant concepts in lecture. Wiki could help me overcome such problems since there are explanations of nearly every concept which are contributed by many people. In general, wiki makes our life and study easier.
