“Yes,we can!”: Perceptions of collective efficacy sources in volleyball

Abstract

Collective efficacy can be defined as a group's shared confidence that they will successfully achieve their goal. We examined which behaviours and events are perceived as sources of collective efficacy beliefs in a volleyball context. In Study 1, volleyball coaches from the highest volleyball leagues (n = 33) in Belgium indicated the most important sources of collective efficacy. This list was then adapted based on the literature and on feedback given by an expert focus group, resulting in a 40-item questionnaire. In Study 2, coaches and players from all levels of volleyball in Belgium (n = 2365) rated each of these sources on their predictive value for collective efficacy. A principal component analysis revealed that the 40 sources could be divided into eight internally consistent factors. Positive supportive communication (e.g. enthusiasm after making a point) was identified as the factor most predictive for positive collective efficacy beliefs. The factor referring to the negative emotional reactions of players (e.g. discouraging body language) was the most predictive for negative collective efficacy beliefs. These findings offer a starting point for the design of continuous measurements of collective efficacy through observation.     

Current State of Numerical Simulations and Testing for the Blast and Impact Protection of the Build Civil Engineering Infrastructure

The identification of the critical infrastructure has shown that the build civil engineering infrastructure is almost involved everywhere, even with the IT-infrastructure. Therefore, the passive safety of structures is demanded. Security associations have analysed that most assaults came along with explosion and impact scenarios, which amount in 80% of assaults. Consequently, these are the extraordinary loads the structures have to be planned and designed for. To carry out such an engineering job, the engineer has to be educated in multiple disciplines as physics, material science , continuum mechanics, numerical mechanics, testing, structural engineering and related specific fields as wave propagation etc. In this paper we will concentrate on the subjects of numerical simulation and testing.     

An examination of the relationship between athlete leadership and cohesion using social network analysis

Two studies investigated the structure of different athlete leadership networks and its relationship to cohesion using social network analysis. In Study 1, we examined the relationship between a general leadership quality network and task and social cohesion as measured by the Group Environment Questionnaire (GEQ). In Study 2, we investigated the leadership networks for four different athlete leadership roles (task, motivational, social and external) and their association with task and social cohesion networks. In Study 1, the results demonstrated that the general leadership quality network was positively related to task and social cohesion. The results from Study 2 indicated positive correlations between the four leadership networks and task and social cohesion networks. Further, the motivational leadership network emerged as the strongest predictor of the task cohesion network, while the social leadership network was the strongest predictor of the social cohesion network. The results complement a growing body of research indicating that athlete leadership has a positive association with cohesion.     

Working memory capacity and reading skill moderate the effectiveness of strategy training in learning from hypertext

Cognitive and metacognitive strategies are particularly important for learning with hypertext. The effectiveness of strategy training, however, depends on available working memory resources. Thus, especially learners high on working memory capacity can profit from strategy training, while learners low on working memory capacity might easily be overtaxed. In addition, efficient basic reading comprehension processes are important for strategy training to be successful: When both the newly acquired strategies and poorly routinized basic reading comprehension processes compete for working memory resources, navigation within the hypertext and learning might deteriorate rather than improve. In an experiment, 64 undergraduates learned with a comprehensive expository hypertext after receiving either a cognitive or a metacognitive or no strategy training. In line with the predictions, learners high on working memory capacity or reading skill could profit from learning strategy training in terms of learning outcomes and the quality of their navigational behavior. Learners low on working memory capacity or reading skill, in contrast, performed worse in both training conditions compared to the control condition. The improvement in learning outcomes for skilled learners as well as the impairment in learning outcomes for unskilled learners could be shown to be indirect effects mediated by the quality of navigational behavior.     

Automated scoring in context: Rapid assessment for placed students

This study investigated the use of automated essay scoring (AES) to identify at-risk students enrolled in a first-year university writing course. An application of AES, the Criterion^® Online Writing Evaluation Service was evaluated through a methodology focusing on construct modelling, response processes, disaggregation, extrapolation, generalization, and consequence. Based on the results of our two-year study with students (N = 1,482) at a public technological research university in the United States, we found that Criterion offered a defined writing construct congruent with established models, achieved acceptance among students and instructors, showed no statistically significant differences between ethnicity groups of sufficient sample size, correlated at acceptable levels with other writing measures, performed in a stable fashion, and enabled instructors to identify at-risk students to increase their course success.     

Can giftedness be taught?

This study investigates the relationship between giftedness and strategic flexibility using cognitive training methodology. The two experiments showed that the metacognitive training influenced strategic flexibility and metacognition of students. The results further showed that it is much easier to enhance performance on closed problems than with open problems which call for creativity.

Direct regional economic impact of Germany’s 1. FC Kaiserslautern through participation in the 1. Bundesliga

In discussions about the use of public money for popular sports such as clubs in Germany’s 1. Bundesliga, it is often argued that the funds are well invested due to the cash flows generated by these organizations for their home regions. However, others claim the opposite. They argue that actually no positive impact is generated and, even worse, that money is leaving the region due to the clubs. The study presented here analyses the financial flows generated by the 1. FC Kaiserslautern for its home city (Kaiserslautern) and home state (Rhineland-Palatinate) during the 2010/11 season when the club participated in the 1. Bundesliga. Based on a 3-step model, the economic impact is calculated by considering spectator spending and cash flows generated by the business activities of the club. It turns out that additional cash flows of approximately €16.5 million and €25.8 million were generated for the state and the city, respectively.     

Is syllable segmentation developmentally constrained by consonant sonority within syllable boundaries in silent reading? Evidence in French children

There is agreement that French typically reading children use syllable‐sized units to segment words. Although the statistical properties of the initial syllables or the clusters within syllable boundaries seem to be crucial for syllable segmentation, little is known about the role of consonant sonority in silent reading. In two experiments that used audio‐visual and visual pseudoword recognition tasks with 300 French typically developing children, we showed a progressive increase in the use of syllable segmentation from the first through fifth years of reading instruction. The children were influenced both by an optimal ‘sonorant coda–obstruent onset’ sonority profile and by the individual position‐dependent consonant sonority within syllable boundaries. Orthographic and phonological statistical properties did not clearly modulate the response patterns. We provide innovative data to help further understand the developmental course of the use of syllable segmentation as determined by sonority. We discuss our results in the light of linguistic principles.
