The Relationship

Surgery is a challenging domain for motor skill acquisition. A critical contributing factor in this difficulty is that feedback is often delayed from performance and qualitative in nature. Collection of highdensity motion information may offer a solution. Metrics derived from this motion capture, in particular indices of movement smoothness, have been shown to correlate with task outcomes in multiple domains, including endovascular surgery. The open question is whether providing feedback based on these metrics can be used to accelerate learning. In pursuit of that goal, we examined the relationship between a motion metric that is computationally simple to compute—spectral arc length—and performance on a simple but challenging motor task, mirror tracing. We were able to replicate previous results showing that movement smoothness measures are linked to overall performance, and now have performance thresholds to use in subsequent work on using these metrics for training.

And Performance

The role of kinesthetic stimulation in motor learning and performance of a gross motor task was investigated. Forty healthy female adult volunteers, ages 20 to 30 years old, were required to learn a gross motor task involving the kicking of a ball. Subjects were randomly assigned to one of two training groups, a kinesthetic stimulus group or a non-kinesthetic stimulus group. Results indicated that kinesthetic stimulation during practice and retention phases seemed to enhance task acquisition. Kinesthetic stimulation may have provided important feedback information for the learners that might have enabled them to make the necessary adjustments during performance. In addition, it appears that the stimulation affected the motor memory processes and left a more stable representation of the movement pattern. The use of continuous pressure as a means of kinesthetic stimulation for the facilitation of motor skill acquisition is recommended, although further research is required in order to generalize these findings to the clinic.

The findings were presented using tables and figures. From the findings in the Hypothesis, the r= 0.509** was obtained. This is significant as the p-value greater than 0.05. This shows that there was a significant relationship between remuneration packages’ and employee performance. The findings also revealed that quick payment of remuneration has great influence on employees’ productivity. The study concluded that remuneration package such as overtime, constant remuneration payment, promotes morale and increase team cohesion. From this finding, it was recommended that, organization should continue providing security benefits to all employees, as it will positively influence employee productivity and raise overall performance in the all sectors. The study also recommends that the organization should continue providing health protection benefits to its employees since it will help them create a sense of loyalty and encourage their productivity in the economic sector. Organizations, especially Breweries PLC should review the current retirement package since a good retirement package will attract and retain employees in the organization and also improve their productivity.

This study investigated the effects of tension-control training by electromyographic biofeedback on learning and performance of a stabilometer balancing task. 30 young adult males were pretested for stabilometer balancing skill, ranked by performance scores, and divided into identical triplicates to form two experimental groups and a control group. All subjects were reevaluated on the stabilometer test following feedback training of the experimental subjects. Analysis of variance of difference means, scores representing performance and tension, indicated that the biofeedback training significantly reduced tension induced by the novel motor skill and significantly improved performance of the motor skill.

Of growing concern to sport researchers is the practice of youth sport athletes specializing in sport at a young age. Sport specialization is characterized by year-round training in a single sport at the exclusion of other sport or nonsport activities. The purpose of this paper is to discuss the potential benefits of specialized sport at an early age in light of the potential risks associated with specialized participation. Three areas of consideration are discussed, including motor skill acquisition and performance, potential sociological consequences, and psychological concerns related to high-intensity training of young athletes. Finally, recommendations for further research and practical considerations are suggested for deciding the appropriateness of specialized sport in the training and development of youth sport athletes.

The Relationship

The records of 426 games played in the twelve team Western Hockey League provided the data for an investigation of the relationships between crowd size and density, and both player aggression (aggressive penalties) and performance (goals). Crowd size was negatively related to the aggression and performance of visiting teams while crowd density was negatively related to the overall performance of both teams. The present and earlier studies suggest an inverted-U function best describes the relationship between the full range of crowd size and player aggression. The importance of a game was negatively related to home team performance and positively related to that of the visitors. Player aggression increased with the number of times any two teams had previously met during the season while intradivisional rivalries were associated with more aggression than interdivisional games.

<p>This research was influenced by Sirmon & Lane's (2004) model of cultural differences and international alliance performance. Sirmon & Lane's model introduced the concept and importance of partners' professional culture compatibility in international alliances. However, to date, their model lacks empirical testing. This research therefore took the study further by empirically investigating the influence of professional culture compatibility between partners and international alliance performance by using a selected sample of Sino-Foreign joint ventures in China. The findings overall support Sirmon & Lane's (2004) model that (1) Partners from similar national cultures experience lesser differences in their professional cultures as opposed to partners from diverse cultures; and, (2) Professional culture differences between partners negatively influence the overall performance of international joint ventures. However, this research also argues that the relationships shown in Sirmon & Lane's (2004) model are not as straightforward as was previously proposed, and the findings suggest several additional factors that contribute to the relationship between partner professional culture compatibility and international alliance performance.</p>

AbstractFor the past decade, human capital has been recognized as one of the crucial assets of any firm’s overall performance. Previous studies widely advocated a linear link between human capital and innovative firm performance, arguing that there are a variety of factors to examine if the relationship between human capital and innovative firm performance is to be properly understood. The focus of this study was to examine the effect of social capital on the relationship between human capital and innovative firm performance. Specifically, it examined the relationship between human capital and social capital and between human capital and innovative firm performance. It also examined the relationship between social capital and innovative firm performance. A total of 294 questionnaires were obtained from managerial staff in automotive companies in Malaysia and the data was analysed using the Partial Least Squares (PLS) test. The results indicated a direct effect between human capital and innovative performance. It was found that human capital is significantly related to social capital and that there is a significant relationship between social capital and innovative firm performance, indicating the ability of social capital to improve innovative firm performance. Finally, it revealed that innovative firm performance could be achieved by human capital through the role of valuable social capital and that good innovative firm performance leads to more prudent and sustainable organisations. The results provide pertinent implications for academia, policymakers and market players while also contributing to the research fields of strategic management, human capital, social capital and performance.
