Context:An athlete’s ability to recover quickly is important when there is limited time between training and competition. As such, recovery strategies are commonly used to expedite the recovery process.Purpose:To determine the effectiveness of both cold-water immersion (CWI) and contrast water therapy (CWT) compared with control on short-term recovery (<4 h) after a single full-body resistance-training session.Methods:Thirteen men (age 26 ± 5 y, weight 79 ± 7 kg, height 177 ± 5 cm) were assessed for perceptual (fatigue and soreness) and performance measures (maximal voluntary isometric contraction [MVC] of the knee extensors, weighted and unweighted countermovement jumps) before and immediately after the training session. Subjects then completed 1 of three 14-min recovery strategies (CWI, CWT, or passive sitting [CON]), with the perceptual and performance measures reassessed immediately, 2 h, and 4 h postrecovery.Results:Peak torque during MVC and jump performance were significantly decreased (P < .05) after the resistance-training session and remained depressed for at least 4 h postrecovery in all conditions. Neither CWI nor CWT had any effect on perceptual or performance measures over the 4-h recovery period.Conclusions:CWI and CWT did not improve short-term (<4-h) recovery after a conventional resistance-training session.

A large number of family firms employ nonfamily managers. This article analyzes the optimal compensation contracts of nonfamily managers employed by family firms using principal—agent analysis. The model shows that the contracts should have low incentive levels in terms of short-term performance measures. This finding is moderated by nonfamily managers’ responsiveness to incentives, their level of risk aversion, and measurement errors of effort related to short-term performance. The model allows a comparison between the contracts of family and nonfamily managers. This comparison shows that the contracts of family managers should include relatively greater incentives in terms of short-term performance measures. A number of propositions regarding the compensation of nonfamily managers employed by family firms are formulated. The implications of the model for family business research and practice are discussed.

Short Term Forecasting

This study examined the applicability of artificial neural network models in modelling univariate time series ambulance demand for short-term forecasting horizons in Zimbabwe. Bulawayo City Councils’ ambulance services department was used as a case study. Two models, feed-forward neural network (FFNN) and seasonal autoregressive integrated moving average, (SARIMA) were developed using monthly historical data from 2010 to 2017 and compared against observed data for 2018. The mean absolute error (MAE), root mean square error (RMSE), and paired sample t-test were used as performance measures. Calculated performance measures for FFNN were MAE (94.0), RMSE (137.19), and the test statistic value p=0.493(>0.05) whilst corresponding values for SARIMA were 105.71, 125.28, and p=0.005(<0.05), respectively. Findings of this study suggest that the FFNN model is inclined to value estimation whilst the SARIMA model is directional with a linear pattern over time. Based on the performance measures, the parsimonious FFNN model was selected to predict short-term annual ambulance demand. Demand forecasts with FFNN for 2019 reflected the expected general trends in Bulawayo. The forecasts indicate high demand during the months of January, March, September, and December. Key ambulance logistic activities such as vehicle servicing, replenishment of essential equipment and drugs, staff training, leave days scheduling, and mock drills need to be planned for April, June, and July when low demand is anticipated. This deliberate planning strategy would avoid a dire situation whereby ambulances are available but without adequate staff, essential drugs, and equipment to respond to public emergency calls.

Educational Issues

Purpose – This paper seeks to explore how principals use their time when the requirement exceeds the activities are desirable. In the scholarly debate it has been pointed out the heads think that too much time is devoted for the financial and administrative issues, or to solve acute problems. This means that there is not enough time to work with educational issues. The purpose of this paper is to clarify how principals use the time they have devoted for the educational area and what activities they prioritize. It will also increase the knowledge of reasons behind their prioritizing and reflect on some of the consequences. Results relate to the question if introduction of performance measures has increased a short-term perspective on student performance or if it works as a suitable tool for the principals to achieve the schools goals and to create more effective schools in the long run. The question if stakeholders can get required insight by the performance measures as they are designed today and if the principals got the right incentives is raised. Design/methodology/approach – A quantitative approach is used and a mail questionnaire was distributed to the principals in all upper secondary schools in Sweden and a comparative cross-sectional study was conducted. Findings – Principals’ perceptions suggest that, their prioritization when working with educational issues is influenced by a more short-term perspective and that they prioritize teaching, which have a much faster impact on student outcome, over long-term school development which facilitate the conditions for the former. These findings increase the insight into the need, for as well stakeholders as principals, to develop performance measures to stimulate change when needed. Practical implications – These findings have implications on the direction of the development of performance measures. The result points out the lack of transparence for stakeholders and uncovers the need to know when change and long-term development is ongoing or not. The study show how principals need incentives for prioritizing these activities and that this can be done by the stakeholder by designing required measurements for as well teaching as long-term school development when change is needed or to maintain a successful process. Originality/value – This paper fulfills an identified need to study how the performance measures of today can be complemented with measures for stakeholders for increased insight in ongoing activities with development and required change for long-term school success.

Retention Trial

2 groups of adult rhesus monkeys, one learning-set-sophisticated (LS-S) and one learning-set-naive (LS-N), were trained on 360 object-quality discrimination problems. Each set of 6 daily problems was followed by one retention trial on each of the original problems. The order of the presentation of the retention trial was counterbalanced. The LS-S Ss had significantly higher acquisition scores and retained a greater absolute number of items than the LS-N Ss. But when the retention scores were adjusted for level of performance on Trial 6 of acquisition, the LS-N animals showed a significantly higher retention score. No serial or sequential effects were found and the results were interpreted as indicating that the learning-set procedure overloaded the short-term memory mechanism of both naive and sophisticated animals, thus eliminating sequence effects. The rapid forgetting of the characteristics of individual items in a learning-set situation would facilitate learning-set performance.
