Unforced errors are a significant issue in producing high performance in tennis. Identifying the causes of these errors in important to guide interventions to reduce unforced errors. The purpose of this study was to examine the different causes of unforced errors (UE) of Women’s Collegiate tennis players from the perspectives of coaches and players. Specifically, and based on previous research (Hirata, Sato, Murakami, Sato, & Saijo, in press; Shibahara, Tamaki, Hirata, Sonobe, Morii, & Saijo, 2015), a measure was developed to collect data on UE. The factor structure was examined using data collected from 283 Collegiate women tennis players and 77 coaches of women tennis players. These participants were divided into High-Skilled (HS) and Low- Skilled (LS), where the criteria for such selection was based in the competition level played in different Competitions. In order to access the HS competition, players needed to be winners of the LS competition. Comparing and contrasting both groups are in the basis of the current research study.

Summary: The Big Five factors structure is currently the benchmark for personality dimensions. In the domain of adjectives, various instruments have been developed to measure the Big Five. In this contribution we propose a methodology to find a simple factorial structure and we apply this methodology to the domain of Big Five as measured by adjectives. Using data collected on a sample of 337 subjects, we propose a five-factor benchmark structure derived from the 50 best marker adjectives selected among the adjectives contained in three instruments specifically developed to measure the Big Five (i.e., Goldberg 's 100 adjectives list, IASR-B5, and SACBIF). We use this common factor structure (or benchmark structure) to investigate the differences and the similarities between the three operationalizations of the Big Five, and to investigate the placements of the full set of adjectives contained in the three instruments. The main features of the proposed methodology and the generalizability of the obtained results are discussed.

Conscious appraisals of stress, or stress states, are an important aspect of human performance. This article presents evidence supporting the validity and measurement characteristics of a short multidimensional self-report measure of stress state, the Short Stress State Questionnaire (SSSQ; Helton, 2004 ). The SSSQ measures task engagement, distress, and worry. A confirmatory factor analysis of the SSSQ using data pooled from multiple samples suggests the SSSQ does have a three factor structure and post-task changes are not due to changes in factor structure, but to mean level changes (state changes). In addition, the SSSQ demonstrates sensitivity to task stressors in line with hypotheses. Different task conditions elicited unique patterns of stress state on the three factors of the SSSQ in line with prior predictions. The 24-item SSSQ is a valid measure of stress state which may be useful to researchers interested in conscious appraisals of task-related stress.

There are few studies that have found an adequate means of assessing firms based on their specific needs for a concurrent engineering (CE) approach. Managers interested in introducing CE have little choice but to rely on their past experiences of introducing change. Using data gleaned from a nine month case study, a British-wide survey and a series of in-depth interviews, this paper summarizes the findings of a research study that examines how firms orientate themselves towards change and how they go about introducing CE to their operations. The data show that there are many benefits to introducing CE and that firms differ with respect to their needs for the CE approach. A tentative means to assess CE ‘needs’ is proposed which is based on the level of complexity of goods produced by firms. The method is currently being developed and extended to provide an applications-based framework to assist firms to improve their new product development performance.

Test anxiety and distress occupy pivotal positions in students' lives today, because of over emphasis on academic achievement in the modern educational system. The need for high performance in examinations has defeated the very purpose of education. The SSC examination has come to be an exhaustive exercise that makes the students learn by rote rather than comprehension. There are a few who feel completely trapped in their situation and indulge in self-destructive acts like suicide. The present research study attempted at understanding the likely role of personality correlates namely, academic self-concept, self-efficacy and locus of control in alleviating the different dimensions of stress encountered by students of standard X. It revealed a significant relationship between stress and the mentioned variables and could have important implications in helping students of standard X come to terms with their invaluable self-worth in effectively coping with the evil of the present century -stress.

Adolescent Functioning

The present study attempts to replicate and extend Snyder et al. (2015, JPSP). The original study examined the latent factor structure of the EATQ-R, a commonly used measure of adolescent temperament, and then showed that the resulting latent factors (i.e., Effortful Control, Negative Emotionality, and Positive Emotionality) had theoretically meaningful concurrent associations with various measures of adolescent functioning (depression, anxiety, ADHD, relational aggression, and school performance and behavior). We performed these same analyses using data from a large sample of Mexican-origin youth (N=674), and also examined prospective associations between the three EATQ-R factors and measures of adolescent functioning assessed two years later. We found some evidence supporting the bifactor model fit reported in the original study but poor replication of the correlations among latent factors. Additionally, model comparisons demonstrated that correlated factors models led to more interpretable factors than the bifactor models. In contrast, we replicated most, but not all, of the concurrent correlations (and extended the findings to prospective associations) between the EATQ-R factors and measures of adolescent functioning, supporting the construct validity of the EATQ-R as a measure of adolescent temperament. Thus, these findings raise concerns about the generalizability of the factor structure identified by Snyder et al. (2015), but bolster claims about the generalizability of the concurrent and predictive validity of the EATQ-R. Overall, meaningful differences between the present findings and those of Snyder et al. highlight the importance of ongoing construct validation in youth temperament research, especially with participants from groups traditionally underrepresented in psychological research.

In this article, we carry out a combined econometric and multiobjective analysis using data from a representative sample of Andalusian schools. In particular, four econometric models are estimated in which the students’ academic performance (scores in math and reading, and percentage of students reaching a certain threshold in both subjects, respectively) are regressed against the satisfaction of students with different aspects of the teaching-learning process. From these estimates, four objective functions are defined which have been simultaneously maximized, subject to a set of constraints obtained by analyzing dependencies between explanatory variables. This multiobjective programming model is intended to optimize the students’ academic performance as a function of the students’ satisfaction. To solve this problem we use a decomposition-based evolutionary multiobjective algorithm called Global WASF-GA with different scalarizing functions which allows generating an approximation of the Pareto optimal front. In general, the results show the importance of promoting respect and closer interaction between students and teachers, as a way to increase the average performance of the students and the proportion of high performance students.

Introduction: Rhythmic gymnastics (RG) is a sport that combines art biomechanical gestures of high complexity, which requires a high level of development of physical qualities such as agility, flexibility, strength, impulsion and dexterity. In this modality studies show that injuries are attributed more articulate knees, ankles, and in some cases ends wrist sprains being the most frequently recorded in athletes in competition level. Therefore, proprioception and muscle control play a fundamental role in dynamic joint stability, since after orthopedic injuries sensorimotor some characteristics are altered and should be focused on rehabilitation programs to get a better return so the activities prior to the injury. Objective: The objective of this project is to evaluate the effect of proprioceptive training on postural balance of athletes in rhythmic gymnastics - RG, from the use of a force platform BIOMEC400 (EMG System do Brazil, Ltda SP). Method: We performed a proprioceptive training in thirty days, in two stages, moving the complexity of the exercises each phase proprioceptive training. Results: We observed that there was a significant improvement in results of training, when it was used more complex exercises and agility exercises before. Conclusion: Because it is athletes RG high performance and present a predominance of activities in one foot, protocols proprioception should be more intensively, generating a higher level of disturbance and postural imbalances.
