ABSTRACT

The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values.  相似文献

Abstract

This article reports a preliminary study of high school students making sense of the behavior displayed by a Lorenzian Water Wheel. The Lorenzian Water Wheel is a rotating disk driven by the flow of water whose motion may be periodic or not, depending on different parameters (e.g., tilt of the wheel, flow rate of the water, and amount of friction). The study aims to contribute toward new basis for the learning of dissipative dynamics through the analysis and experimentation with common phenomena. The study also aims to support the design of learning environments that focus on fundamental aspects of dissipative dynamics‐such as the origins of turbulence, the relationships between periodicity and predictability, or the notion of an attractor—by refining intuitions that emerge from the daily experience with the surrounding world.  相似文献

Bearing in mind students' misconceptions about basic concepts in astronomy, the present study conducted a series of constructivist activities aimed at changing future elementary and junior high school teachers' conceptions about the cause of seasonal changes, and several characteristics of the Sun–Earth–Moon relative movements like Moon phases, Sun and Moon eclipses, and others. The activities and results concerning the cause of seasonal changes are reported. Both the experimental class and the control groups improved their grasp of basic astronomy concepts statistically significantly, although the experimental class made the most impressive progress of all. Regarding subjects relevant to this study (seasonal changes), only the experimental class showed a statistically significant improvement, which justifies the constructivist approach. We conclude that in implementing a reform in the science curriculum, the change has to include the subjects taught and also the way they are taught. © 2006 Wiley Periodicals, Inc.

Conclusion A detailed and exact evaluation of this program of Teacher Formation and of theactivities of academic counsellors is presently underway. We expect to have theresults by the middle of 1982. Nevertheless, partial evaluations of differentteaching and counselling activities show that there has been a change in the conceptionof what education is, development of aptitudes and attitudes and a profoundimprovement in the teaching quality.  相似文献

Conclusion It is necessary to realize the limitations of counselling services in Mexico. In spite of all the efforts taken, the academic preparation of counsellors is not strong enough. As has been mentioned, 50% are psychologists or pedagogues, at best, and the rest, who are not specifically prepared for counselling, are constantly moving away from the helping services. There seems to be little progress. On the other hand, we hope that counselling and the counsellors, once services have been established, might some day be able to resolve those complex problems which the educational system has not been able to resolve or diminish with its own traditional resources, especially problems like school dropout, the correct choice of vocational and academic studies, the distribution of students to the various branches and levels of the educational system in accordance with the actual needs of the country, and a whole series of other tasks, which may fail in an area of myth or may really be related to the possibilities of the discipline. Therefore, it is necessary to set the limits of counsellors' tasks and to define the counsellor's role more clearly in the near future, in order to strengthen the discipline on behalf of our future students.Knowing, understanding and evaluating the relationship that now exists between the counselling tasks of counsellors, the educational Practice and the national and international policy, shall facilitate the future implementation of more solid and feasible programmes. For the time being, having a clear view of what we can do (and not only justifying things we cannot accomplish) should help our students to use our counselling services with higher benefits.  相似文献

Teaching in general and teachingof mathematics in particular are matters ofgreat importance for contemporary society.Over the years, societies have establishedinstitutions in order to incorporatemathematics and science into the culture ofsociety with the clear intention ofencouraging a scientific vision of theworld among the population. This intensesocial process of scientific enlightenment has helped us recognize theneed to implement educational modificationsin the specific field of mathematics basedon designs that are better adapted toschool practices. Mathematics educationdeals with the systematic study of theeffects of such processes; in this paper,we have decided to describe a certainevolution of its research problems. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Diversity has been an important topic of research for some time in higher education, though the purposes underlying this attention have varied across national and regional contexts. In many parts of the world, the term diversity has been emphasized with regard to variety among the programs or services provided by academic institutions, and differences among the types of institutions themselves. It is particularly important to discuss whether different dimensions of diversity may influence the degree of effectiveness of higher education (HE) in fulfilling its contribution and relevance to economic and social development. We are particularly interested in analyzing whether unitary or binary systems present significant differences in different dimensions of diversity that may be relevant to enhance higher education institutions’ (HEIs) contribution to territorial cohesion, notably by enhancing the local stock of human capital and contributing to the social and cultural development of their regions. Therefore, we propose the following research questions: *Are there relevant patterns regarding different dimensions of diversity between unitary and binary HE systems? *In the case of binary systems, is it possible to find relevant differences in different dimensions of diversity between universities and more vocational HEIs? By looking at these questions, we aim at contributing both to the literature on HE institutional diversity and to the study of the role played by HEIs on regional development.  相似文献

The aims of this study were to identify differences between the sexes in extra-curricular participation in sports and to determine its association with body fat and socio-demographic factors in Spanish adolescents. A total of 2165 adolescents (1124 males and 1041 females) aged 13.0-18.5 years from the AVENA Study participated. Participants filled in an ad hoc questionnaire for extra-curricular participation in sports, which was the dependent variable. Independent variables were: age, percent body fat, and father's and mother's educational level and occupation. Chi-square tests and logistic regression were applied. Bivariate analysis showed for male adolescents that age and father's occupation were related to extra-curricular participation in sports. In addition, body fat and mother's education and occupation (all P?相似文献
