A flexible mathematical model for the planning and designing of a sporting fixture by considering the assignment of referees

Indexación: Scopus.This paper deals with the problems faced with the designing and planning of a sporting fixture considering correct referee assignments. A non-linear binary program model is proposed to solve the problems, which aims to minimize the sums of the differences that exist between the requirements of each match and the quality of the referee assigned achieving the design of the most adequate referee for each match. The efficiency of the proposed model is proved using some real data obtained from various fixtures for sports such as soccer, volleyball, and basketball. The mathematical model is solved by using CPLEX 12.7.0., which allows the automatic linearization of the problems. The results obtained demonstrate the efficiency of the proposed methodology for tackling problems, as well as its extension to other sporting disciplines, which require a similar type of planning. Similarly, given the robust nature of the proposed model, it is possible to implement other objective functions in accordance with the requirements of each league. © 2019 by the authors; licensee Growing Science, Canada.http://growingscience.com/beta/ijiec/2960-a-flexible-mathematical-model-for-the-planning-and-designing-of-a-sporting-fixture-by-considering-the-assignment-of-referees.htm

Player Productivity and Performance: An Econometric Approach to Team Management in Soccer

The motivation for this thesis concerns worker productivity as estimated from production functions. Identifying worker contributions allows for not just an understanding of economic theory but highlights ways in which business management and strategy can be more efficient. The setting for these analyses is professional soccer, where teams are analogous to businesses and workers are multi-million dollar assets in the form of players. Most of a soccer team’s income is tied to its success on the field and so a careful management of staff and players is necessary to their business potential. Sports are the perfect “laboratory” to study economic theory since workers can be observed on a regular basis and there is a large volume of existing data. With almost every game recorded in the modern age this allows for the opportunity to analyse not just worker productivity but also team processes and strategies. This thesis expands the production function literature using a framework from contest theory literature. Most research in soccer focuses on performance at the aggregate level while this thesis primarily considers performance at the player level. It consists of three papers, each providing a different insight into player productivity. Chapter I presents a brief introduction of the relevant literature and contextualizes the research. Chapter II measures the impact of different workers in a production process depending on their expected productivity, finding support for superstar theories over the O-Ring theory in the English Premier League. Chapter III looks at the effects of fatigue in professional soccer finding that under current scheduling in the English Premier League and European competition there are no statistically significant effects of receiving different days of rest on team performance. Chapter IV applies high dimensional techniques to European soccer data to predict match outcomes. The models perform almost as well and betting firms and can be used to estimate individual player contributions in the form of rankings. Chapter V concludes.PHDSport Management PhDUniversity of Michigan, Horace H. Rackham School of Graduate Studieshttps://deepblue.lib.umich.edu/bitstream/2027.42/147502/1/gbwilkin_1.pd

With God on their Side

'Sport' and 'religion' are cultural institutions with a global reach. Each is characterised by ritualised performance and by the ecstatic devotion of its followers, whether in the sports arena or the cathedral of worship. This fascinating collection is the first to examine, in detail, the relationship between these two cultural institutions from an international, religiously pluralistic perspective. It illuminates the role of sport and religion in the social formation of collective groups, and explores how sport might operate in the service of a religious community. The book offers a series of cutting-edge contemporary historical case-studies, wide-ranging in their social and religious contexts. It presents important new work on the following fascinating topics: * sport and Catholicism in Northern Ireland * Shinto and sumo in Japan * women, sport and the American Jewish identity * religion, race and rugby in South Africa * sport and Islam in France and North Africa * sport and Christian fundamentalism in the US * Muhammad Ali and the Nation of Islam. With God on their Side is vital reading for all students of the history, sociology and culture of sport. It also presents important new research material that will be of interest to religious studies students, historians and anthropologists

Deviant Subjectivities: The Ultra Movement and the Governance of Public Affects

This dissertation examines the global proliferation of the ultra movement, a participatory style of sports fandom that entails collective continual singing, jumping, flag-waving, and the illegal lighting of marine flares on the streets and in stadiums. Having spread across six continents, ultra is seen by scholars (Gabler 2013) and many of its participants as a social movement that champions the continuation of traditional, spectator-based fandoms, which revolve around consistent attendance and crowd participation in contrast to TV viewership. The contrast between ultra and other mass political movements is that its social life is highly critical of the consumptive and individualistic aspects of neoliberal citizenship, but not necessarily married to the debates and issues of institutionalized politics. Based on over two years of cumulative field research in Ireland and Germany with the ultra groups of three clubs (Shamrock Rovers FC, FC Union Berlin, and Eis Hockey Club Dynamo Berlin), I find ultras’ performative style of support in the stadium to be a form of social commentary and protest that is based in part on their friction with the state, the mainstream media, and the commercial priorities of sports’ governing bodies. A look into the ultra movement provides a space in which to examine how broader structures of power attempt to suppress groups that deviate from dominant idealizations of the liberal democratic subject
