Can we be satisfied with our football team? Evidence from spanish professional football.
2009
This article assesses the sporting performance of Spanish professional football teams at competition level, namely, League, King’s Cup, and European competitions (Champions League and Union of European Football Associations [UEFA] Cup). Then, the gap between the result obtained by a team at the end of a season and that expected according to its potential is used as a proxy of the degree of satisfaction that fans should feel: the narrower the gap the greater the level of satisfaction. Regarding methodology, Data Envelopment Analysis techniques and directional distance functions are used. Results reveal that most teams perform rather differently across competitions, the lower average performa…
Effect of intra-organisational competition on organisational performance indicators
2021
The objective of the research is to investigate intra-organisational competition (IOC) emerging from the interactions of internal social comparison (ISC) and intra-organisational evolution (IOE) effecting organisational performance (OP). Communication between subordinates, comparing contribution, ability to perform and business management strategies resulting in IOC. The attention is on recognised social dimensions and equal emphasis is on business management practices. The literature attempts’ to recognise ISC and IOE and its effect on OP balances the conceptual paper. For the purpose Google Scholar, Emerald Insight, EBSCO Host and Science Direct database has been used. Literature relies o…
Identifying individuality and variability in team tactics by means of statistical shape analysis and multilayer perceptrons.
2012
Abstract Offensive and defensive systems of play represent important aspects of team sports. They include the players’ positions at certain situations during a match, i.e., when players have to be on specific positions on the court. Patterns of play emerge based on the formations of the players on the court. Recognition of these patterns is important to react adequately and to adjust own strategies to the opponent. Furthermore, the ability to apply variable patterns of play seems to be promising since they make it harder for the opponent to adjust. The purpose of this study is to identify different team tactical patterns in volleyball and to analyze differences in variability. Overall 120 s…
Tactical metrics that discriminate winning, drawing and losing teams in UEFA Euro 2012®
2015
The objectives of this article are twofold: first, an innovative approach to notational analysis in football is outlined. By considering the important theoretical requirements for the analysis of sports games (like the interaction between two parties, the procedural sequence of action or the significance of tactical behaviour) the meaning of the introduced parameters, called tactical metrics, is illustrated. In a second step, the validity of this approach is tested using matches of the Union of European Football Associations (UEFA) Euro 2012® to investigate a connection between these metrics and success. The results show that 11 tactical metrics model tactical behaviour in 4 different dimen…
Tournament structure and nations' success in women's professional tennis
2007
The relationship between domestic professional tournament structure in women's tennis and the subsequent professional ranking success of a nation's female players is examined. The 2003 women's professional tennis tournament calendar provided the distribution of events in 33 countries. Criteria used to classify nations' success in women's professional tennis were as follows: number of players with Women's Tennis Association (WTA) points, number of players with Top 200 rankings, and the combined WTA ranking of a nation's Top 5 female players. Pearson product - moment correlations were performed between the number of tournaments and the three criteria. Considerable variation was observed in th…
Effects of self-myofascial release: A systematic review.
2015
Summary Background Self-myofascial release (SMFR) is a type of myofascial release performed by the individual themselves rather than by a clinician, typically using a tool. Objectives To review the literature regarding studies exploring acute and chronic clinical effects of SMFR. Methods PubMed and Google Scholar databases were searched during February 2015 for studies containing words related to the topic of SMFR. Results Acutely, SMFR seems to increase flexibility and reduce muscle soreness but does not impede athletic performance. It may lead to improved arterial function, improved vascular endothelial function, and increased parasympathetic nervous system activity acutely, which could b…
Comment les stresseurs influencent-ils la performance des comptables ? Equations structurelles méta-analytiques
2019
National audience; Cette recherche vise à combiner les études sur les liens entre les stresseurs et la performance en cabinets comptables et d’audit et à identifier les médiateurs et modérateurs des relations entre stresseurs et performance. En utilisant des méta-analyses et analyses des pistes causales, cette recherche compile 60 études pour investiguer les relations des stresseurs avec la performance des comptables et auditeurs. Comme supposé, les méta-analyses des corrélations bivariées suggère que (1) les stresseurs au travail affectent négativement la performance, (2) l’épuisement professionnel et le stress sont reliés négativement à la performance, mais (3) la motivation est associée …
A grid representation for distributed virtual environments
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environments (DVE) very common nowadays. The architecture and behavior of these systems are very similar to new grid computing applications where concepts such as sharing and high scalability are extremely exploited. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective DVE system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the arbiters (servers) in the system. As an alternative to the ad-hoc heuristic proposed in the l…
Achieving energy efficiency in data centers with a performance-guaranteed power aware routing
2017
Nowadays, data centers are designed to offer the highest performance in case of high traffic load and peak utilisation of the network. However, in a realistic data center environment, the peak capacity of the network is rarely reached and the average utilisation of devices varies between 5% and 25% which results into a huge loss of energy since most of the time links and servers are idle or under-utilized. The high impact of this wasted power on environmental effects, energy needs and electricity costs raised the concerns to seek for an efficient solution to make data centers more power effective while keeping the desired quality of service. In this paper, we propose a power-aware routing a…
Comparison of implementations of the lattice-Boltzmann method
2008
AbstractSimplicity of coding is usually an appealing feature of the lattice-Boltzmann method (LBM). Conventional implementations of LBM are often based on the two-lattice or the two-step algorithm, which however suffer from high memory consumption and poor computational performance, respectively. The aim of this work was to identify implementations of LBM that would achieve high computational performance with low memory consumption. Effects of memory addressing schemes were investigated in particular. Data layouts for velocity distribution values were also considered, and they were found to be related to computational performance. A novel bundle data layout was therefore introduced. Address…
