Individual differences of action orientation for risktaking in sports

The goal of this article is to explain empirical risk-taking behavior in sports from an individual cognitive modeling perspective. A basketball task was used in which participants viewed four video options that varied in the degree of associated risk. The participants were independently classified by scores on the Questionnaire for Assessing Prospective Action Orientation and State Orientation in Success, Failure, and Planning Situations as action-oriented or state-oriented decision makers. The results of the experiment show that action-oriented players shoot faster and more often to the basket and that state-oriented players prefer to pass to a playmaker more often. Four versions of a computational model of decision making, Decision Field Theory, were compared to evaluate whether behavioral differences depend on the focus of attention, the initial preferences, threshold values, or an approach-avoidance interpretation of the task. Different starting preferences explained individual choices and decision times most accurately. Risk taking in basketball shooting behavior can be best explained by different preferences for starting values for risky and safe options caused by different levels of action orientation.

A stigma power perspective on digital government service avoidance

The digital-by-default policy for government services implemented in many European countries can pose challenges to marginalized citizens, such as people with disabilities. Prior research on electronic inclusion and the digital divide has mainly considered technology-related concerns, such as Internet anxiety, preventing people with disabilities from using digital government services. Yet, these concerns may insufficiently account for the fact that people with disabilities may suspect that governments provide new services only to reduce costs and forgo the need for more meaningful social change. Therefore, we draw from stigma power theory to understand how perceptions of stereotyping and discrimination contribute to the avoidance of digital government services among people with disabilities. Our results indicate that overcoming underutilization of digital government services among people with disabilities requires a holistic approach by addressing technology-related as well as stigma-related concerns.     

Two Worlds of Academic Publishing: Chemistry and German Sociology in Comparison

The communication infrastructure of modern science is provided by profit-oriented business firms: the publishing houses which print and distribute academic books and journals. Surprisingly, beyond some rather superficial impressions, in science studies little is known about how academic publishers work—in particular, how markets for books and journals look like, how publication decisions are taken, and how the interplay with the scientific community is arranged. We address these questions with a focus on the relation between economic considerations of publishers, on the one hand, and the requirements of scientific communication, on the other. Our contrasting case studies are a very large worldwide operating publisher with regard to chemistry publications and a national publishing house of German sociology. At first, we show how the rather different business approaches of the two types of academic publishing houses look like. Both approaches could reach stability for some time which means not only that publishers earned money according to their profit aspirations but also that the communication requirements of science were sufficiently met. Afterwards, we point out the instabilities that have begun to arise in both fields and may sooner or later erode the former fit of profit-making and scientific communication.     

Allowing learners to choose: self-controlled practice schedules for learning multiple movement patterns

For this study, we investigated the effects of self-controlled practice on learning multiple motor skills. Thirty participants were randomly assigned to self-control or yoked conditions. Participants learned a three-keystroke pattern with three different relative time structures. Those in the self-control group chose one of three relative time structures before each of 90 practice trials; yoked participants were not allowed to choose but were yoked to a self-control participant and followed that individual's sequence of practice trials. Results of the 24-hr serial transfer test revealed the self-control group exhibited significantly lower relative timing error, absolute error, and total error than the yoked group. Findings further support the efficacy of self-controlled learning     

When to blink and when to think: preference for intuitive decisions results in faster and better tactical choices

Intuition is often considered an effective manner of decision making in sports. In this study we investigated whether a preference for intuition over deliberation results in faster and better lab-based choices in team handball attack situations with 54 male and female handball players of different expertise levels. We assumed that intuitive choices-due to their affective nature--are faster when multiple options are to be considered. The results show that athletes who had a preference for intuitive decisions made faster and better choices than athletes classified as deliberative decision makers. It is important that experts were more intuitive than near-expert and nonexpert players. The results support a take-the-first heuristic defining how options are searched for, how option generation is stopped, and how an option is chosen. Implications for the training of intuitive decision making are presented.     

Strategy development based on intangibles in SMEs – an integrated approach

The approach in this paper is based on the principles of action research and rapid prototyping. The paper shows the current status of a ‘bottom-up’ research process dedicated to continuously developing and improving management instruments that suit the requirements of small and medium-sized enterprises (SMEs): pragmatic, easy-to-use and generating direct practical benefit. As a result, this paper links the concept of intangibles to the practical strategy development process in SMEs. The integration shown concerns several challenges: (1)?Integrate the internal and external perspective on intangibles, and, by that, link the concept of intellectual capital (IC) as a resource-based view with the concept of customer value as a market-based view. (2)?Integrate the theoretical concept of IC with a methodology for comprehensive strategy development. (3)?Integrate the formulation and implementation of business strategies taking into account the actual practice in SMEs.     

Physical attractiveness and monetary success in German Bundesliga

That attractive people are more successful has been proved for many areas of life in the past. However, the effects of the attractiveness of professional athletes have not been examined yet. This is surprising as it is comparatively simple to measure the actual performance of this group of people and to control their performance in statistical models. In the study, 438 professional football players were examined who played in the 18 teams of the German Bundesliga in 2007 and 2008. It was analyzed how their facial and bodily attractiveness influence their market value. Bodily attractiveness was operationalized using the Body Mass Index, facial attractiveness was measured using the Truth of Consensus Method. Statistical analysis shows that both facial and bodily attractiveness have considerable effects on a player’s market value even if his actual performance is controlled.
