The aim of this experimental study was to test Wegner’s (1994) theory of ironic processes in a basketball free throw task under pressure. More specifically, Wegner (1994) predicts that when instructed not to perform in a certain manner performers’ performance will break down where it is least desired way which is the main hypothesis of the current study. More specifically, it was hypothesized that when basketball players were instructed “not to throw the ball’’ into the certain zone on the backboard would decrease their performance in ironic fashion especially under manipulated high-anxiety condition. The sample of the present study comprised 37 male (Mage=22.30, SD=2.89) experienced university basketball players. Participants’ anxiety was measured using MRF-3 (Krane, 1994). In a basketball free-throw task; the numbers of targets, non-target non-ironic balls and ironic error balls were counted and overall performance was also calculated in order to measure participants’ performance. Based on the scoring system, participants gained +5 points for throwing into the target, scored -5 points making an ironic error and 0 points for throwing the ball to anywhere (except the target and non-target ironic error zone) on the backboard. Results revealed that when instructed not to throw in a certain zone, performers’ overall performance changed in ironic fashion across anxiety conditions. Findings suggest that understanding the mechanism of ironic processes of mental control theory may be a useful theoretical framework for examining the relationship between anxiety and performance in sport, physical education and motor control studies.

Purpose The purpose of this paper is to develop an integrated model assessing the frequency and timing between reports on the Association for the Advancement of Sustainability in Higher Education (AASHE) Sustainability Tracking, Assessment and Rating System (STARS) reporting the framework by higher education institutions (HEIs) and the relationship between the STARS score and reputation (enrollment), finances (endowment) and performance (emissions). Design/methodology/approach The development of the theoretical model is based on learning, signaling and legitimacy theories. This study collects data from the AASHE STARS to indicate the rating level of 202 HEIs, control variables, enrollment, endowments and emissions. The hypotheses were tested using generalized linear models. Findings Findings suggest that as HEIs report on their sustainability activity, they learn to report better but that there is also an “un-learning” aspect if the HEI skips reporting in a period. The results support the main hypothesis that there is a relationship between reporting and engagement with the HEIs in the form of enrollment and endowments. Finally, the findings provide evidence that the HEIs’ reporting is associated with a reduction in emissions. Practical implications The findings suggest that HEIs should develop a reporting strategy on a standardized framework such as AASHE STARs and they ought to codify the approach to learn from prior reporting. Students and alumni are increasingly seeking to engage the HEI in the sustainability process and the report is a mechanism for signaling activities. Social implications The findings suggest that AASHE STARS scores may be used by HEIs as a signaling mechanism to stakeholders of their commitment to sustainability. The signal is a mechanism to reduce information asymmetry between the HEI and stakeholders who may want more information on the institution’s attempts toward sustainability but lack access to information. Further, HEI partners have a mechanism to assess the overall level of commitment of the HEI toward sustainability and can, therefore, engage accordingly. Originality/value There has been significant work on signaling theory and sustainability. However, the relationship between STARs reporting as a signal that legitimates the HEI, learning how to report well and HEI performance has received less attention. The current study demonstrates that the STARS framework as a reporting mechanism signals the HEIs’ level of commitment to sustainability thereby legitimating it resulting in improved performance.

PurposeThis study aims to adopt the Altman model in order to predict the performance of industrial companies listed on the Palestinian Stock Exchange during the period of time between 2013 and 2017.Design/methodology/approachThe study sample consisted of 12 industrial companies listed on the Palestine Stock Exchange, and their financial disclosure period extended for 5 years. Multiple linear regression model was used in the analysis to determine the relationship between the independent variables and the dependent variable where the independent variables were (X1, X2, X3). This study is based on one basic assumption, which is that the Altman's model cannot predict the performance of the Palestinian industrial sector.FindingsThe results of the analysis proved the negation of the zero main hypothesis. This means that Altman's model can predict the performance of the Palestinian industrial sector at the level of statistical significance (a = 0.05), as well as the existence of a statistically significant relationship between each of the independent variables (X2, X4, X5) and the dependent variable (Log (Z-score)). Hence, the relationship of X1 and X3 with the dependent variable was not statistically significant.Social implicationsThis paper highlights different challenges that face the adaption of Atman's model and performance prediction in the Palestinian industrial sector. The findings of the analysis have the potential to help future researchers in examining and dealing with new challenges.Originality/valueThis paper presents a vital review of adopting Altman's model in the Palestinian industrial sector. A number of recommendations have been made, the most important of which is that most of the companies are located in the red zone. The Altman's model must be adapted in order to fit the Palestinian environment according to the results of statistical analysis and according to a proposed model, which is Log (Z) = −0.653 + 0.72X2 + 0.18X4 + 0.585X5.

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.

This Study Aimed At Assessing The Effects Employees’ Remunerations On Productivity In The In Nigerian Breweries Plc. This Study Was Guided by three research objectives namely; to identify and discuss various forms of remuneration package in use, to examine the effects of remuneration packages on employees performance and to establish the relationship between improved remuneration and productivity in the Nigeria breweries. The study used descriptive research design. The population of this study consists of all staff working at the Nigerian Breweries PLC Ibadan. Sample of one hundred and twenty respondents were selected. A structured questionnaire was used to collect data from the respondents. The descriptive statistics employed include; frequencies and percentage and the relationship between independent and dependent variables were established using Pearson Product Moment Correlation coefficient with the use of (SPSS). 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.

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.

The aim of this study was to test the predictions of attentional control theory using the quiet eye period as an objective measure of attentional control. Ten basketball players took free throws in two counterbalanced experimental conditions designed to manipulate the anxiety they experienced. Point of gaze was measured using an ASL Mobile Eye tracker and fixations including the quiet eye were determined using frame-by-frame analysis. The manipulation of anxiety resulted in significant reductions in the duration of the quiet eye period and free throw success rate, thus supporting the predictions of attentional control theory. Anxiety impaired goal-directed attentional control (quiet eye period) at the expense of stimulus-driven control (more fixations of shorter duration to various targets). The findings suggest that attentional control theory may be a useful theoretical framework for examining the relationship between anxiety and performance in visuomotor sport skills.

<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>

Research background and hypothesis. While for some authors team sport players should have a high VO 2 max, we hypothesize that there exist a non-linear relationship between VO 2 max and basketball performance. Research aims. Research aims were to study the correlation between basketball performance and VO 2 max in young elite basketball players and the effects of VO 2 max training on performance.Research methods. In the fi rst study, 67 high-level young basketball players performed a shuttle-run test (SRT) to measure their VO 2 max. Competition performance assessed through statistics ratings of 5 matches was determined for all players. The correlation between VO 2 max and performance was calculated. In the second study, the VO 2 max and the competition performance of 34 high-level young male players was assessed as in the fi rst study. The sample was divided into control and experimental groups, which trained their VO 2 max. At the end of the training period all participants repeated the SRT. The results of 4 games played before the fi rst test and 4 games played after the second test (against the same opponents) were compared in both groups.Research results. In the fi rst study we found a correlation of VO 2 max with steals in both groups. In the second study, the experimental group increased their VO 2 max and steals per game, but they decreased free throw per game and free throw percentage. Discussion and conclusions. No correlation was found between VO 2 max and competitive performance in this study, and increased VO 2 max had no effect on most of the studied variables. The data therefore suggest a non-linear relationship between VO 2 max and basketball performance.Keywords: aerobic capacity, basketball performance, non-linear relationship.
