Evaluation of soccer players under the Moneyball concept

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.     

Computer-aided Hypermedia for Learning and Self Studies

A complete coverage of the course content does not lead the student to explorative curiosity and to a scientific attitude to knowledge and learning. Interactive hypermedia use will lead to an epistemological quality raising since in that way students’ independence in planning, knowledge acquisition and problem solving might be facilitated and since at the same time tutorial supervision and guidance can be included. Hypermedia have possibilities to provide students with large quantities of information. With network interfacing learning can take place independent of time and place and individualized education will be possible. Combined with CMC (computer mediated communication) and educational software the student has a tool for life-long education within the classroom. At the Växjö University text, images and simulations have been integrated within a hypertext system: Hyperbook (for Macintosh). At the Royal Institute of Technology we develop this concept to use it with computer-based self-study material in mechanics, a project which started in autumn 1990 using HyperCard. At the University of Lund a development of hypertext material in the form of computer illustrated text for a thermodynamics textbook has just started. An example of limits of models will be demonstrated by a computer simulation of a linearized and a non-linearized pendulum.     

Active Learning and Teaching through Digital Technology and Live Performance: ‘Choreographic Thinking’ as Art Practice in the Tertiary Sector

This article is an interdisciplinary reflective response to an intensive studio learning and teaching experience involving artists, academics and postgraduate students. The authors of this article teach, research and practise in coding, digital design, dance, and virtual and live performance. As lecturers and students we reflect upon and propose future approaches to art practice in tertiary education informed by live performance, performance capture and studio‐based responses to digital and virtual platforms. We reflect on an innovative contribution to the field of research–teaching nexus as informed by digital and virtual data capture identifying the key element of immediacy in live performance and choreographic improvisation with systems. We reflect on practice‐based inquiry via the Choreographic Coding Lab (CCL) model – a dialogical negotiation between capture technology and interdisciplinary artists in industry and academia. How can we encourage potential studio inquiry as an adapted model in tertiary learning and teaching? Our interdisciplinary voices, presented as authors’ reflections, provide suggestions for future studio‐based, active learning contexts.     

Fostering Authentic Problem Seeking: A Step Toward Social Justice Engagement

Because of these learners’ potential as future leaders, it is imperative that educators develop gifted students’ ability to identify and solve complex social justice problems. Nourishing students’ affective traits, including empathy for others, understanding of themselves, and the ability to connect to others in local and global society, will help students to recognize and seek out authentic problems. This article examines the nuances around the creative problem-solving process and how educators can infuse the curriculum with opportunities to develop and strengthen the skills students need to become engaged, real-world problem seekers, as we call it, and problem solvers. Through the combination of social justice issues and creative problem seeking, students can be motivated to engage with the community and promote positive change in the world.
