No confidence–no glory? Coach behavioral bias and team performance
According to behavioral economics, coaches may be unconsciously biased, and this could lead to deviations from rational behavior, which in turn affects team performance. We analyze the influence of a particular behavioral bias of coaches, overconfidence, on the performance of soccer teams. We use a sample of 63 coaches managing all the soccer clubs involved in the Russian Football Premier League during the four seasons between 2010 and 2013/2014. To measure overconfidence, we use a press-based metric that is generally accepted in corporate governance studies and complement it with an additional continuous measure. Coaches' overconfidence positively and significantly influences team average scores, both in the baseline regression and robustness checks. Additional testing allows us to draw conclusions regarding the inverse U-shaped relationship between overconfidence and performance. We cannot conclude that overconfidence has any effect on coaches' risk-taking that can be approximated by goals scored or allowed. We apply the well-studied methodology of overconfidence measurement to the new field of sport economics, thereby generating novel results. Although overconfidence is perceived negatively in corporate governance, we show that in sport, it is beneficial to be overconfident. The findings contribute to sport literature, more specifically to the field of performance in soccer, with results that support the importance of a coach's personal traits.
This article advances the idea of cultural and individual values being connected to each other not directly, but through the consciousness and activity, which presupposes the integral unity of cultural-historic methodological approach and the activity methodological approach in psychological researches. Activity effects mainly on forming of the consciousness and personality: it underlies them. In the cultural-historic approach such basis, in a way, a unit of analysis of consciousness and personality, is a value-oriented experience. The necessity of integration of the activity approach with cultural-historic approach lies in the integral ontology of psyche, behavior, activity, experience, sense, consciousness, personality, culture and its values.
The article discusses the process of formation and evolution of the concept of Free will in the period of late Anquity and Middle Ages and also reasons of the fact that this concept became a foundation of European interpretation of personality and social teaching of the Catholic Church. The analysis was conducted on the basis of official legal documents of the Catholic Church, as well as on the basis of writings of Doctor of the Church. The compilation of theological and legal approaches makes it possible to assess influence of the catholic teaching on the formation of legal doctrine and West European mental model in comparative perspective.
It analyses polysemantic terms the subject, the personality, the selfhood and which form sincrets for example subjectivity of selfhood and etc. It reconstructs interpretation of these terms by G.G. Shpet, S.L. Rubinshtein, B.M. Teplov, A.N. Leontiev, etc. It affirms that the main theme of psychological investigation is the personality. On the ontological plane we have two ways of personality: down - to the subject - to a function or to collection of functions, to subject; and up - to the selfhood - to an ideal, to the limit of self-construction, to spirituality and freedom.
This book constitutes the refereed proceedings of the 23rd Annual Symposium on Combinatorial Pattern Matching, CPM 2012, held in Helsinki, Finalnd, in July 2012. The 33 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 60 submissions. The papers address issues of searching and matching strings and more complicated patterns such as trees, regular expressions, graphs, point sets, and arrays. The goal is to derive non-trivial combinatorial properties of such structures and to exploit these properties in order to either achieve superior performance for the corresponding computational problems or pinpoint conditions under which searches cannot be performed efficiently. The meeting also deals with problems in computational biology, data compression and data mining, coding, information retrieval, natural language processing, and pattern recognition.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.

At present many industries reveal tendency for setting up of vertically integrated companies (VIC) the structure of which unites all technological processes. This tendency proved its efficiency in oil industry where coordination of all successive stages of technological process, namely, oil prospecting and production -oil transportation - oil processing - oil chemistry - oil products and oil chemicals marketing, is necessary. The article considers specific features of introduction of "personnel management" module at enterprises of oil and gas industry.
