And Task

Postural sway has been demonstrated to increase following exposure to different types of motion. However, limited prior studies have investigated the relationship between exposure to normative on-road driving conditions and standing balance following the exposure. The purpose of this on-road study was to quantify the effect of vehicle motion and task performance on passengers’ post-drive standing balance performance. In this study, trunk-based kinematic data were captured while participants performed a series of balance exercises before and after an on-road driving session in real-time traffic. Postural sway for all balance exercises increased following the driving session. Performing a series of ecologically relevant visual-based tasks led to increases in most post-drive balance metrics such as sway position and velocity. However, the post-drive changes following the driving session with a task were not significantly different compared to changes observed following the driving session without a task. The post-drive standing balance performance changes observed in this study may increase vulnerable users’ risk of falling. Wearable sensors offer an opportunity to monitor postural sway following in-vehicle exposures.

And Task

We investigated the mediating effects of positive affect and strengths use in the relationship between perceived organizational support for strengths use (POSSU) and employees' task performance. Data were gathered at 2 time points, separated by a 2-week interval, from 157 employees working in various Chinese enterprises. We applied structural equation modeling and PROCESS macro analysis to the data. The results indicate that POSSU was positively related to task performance and that this relationship was mediated by strengths use. In addition, positive affect and strengths use played a sequential mediating role in the relationship between POSSU and task performance. However, positive affect was not a significant mediator in the POSSU–task performance relationship. Theoretical and managerial implications are discussed in the context of the literature on POSSU and task performance.

Purpose The purpose of this paper is to examine the mediating role of burnout (i.e. exhaustion, cynicism, professional inefficacy) in the relationship between job level and job satisfaction as well as between job level and task performance. Design/methodology/approach The final sample included 342 Korean workers from selected companies. The authors employed the Hayes (2013) PROCESS tool for analyzing the data. Findings The results showed that all three subscales of burnout (i.e. exhaustion, cynicism, professional inefficacy) mediate the relationship between job level and job satisfaction. However, only two mediators (i.e. cynicism, professional inefficacy) indicated the mediating effects on the association between job level and task performance. Originality/value This research presented the role of burnout on the relationships between job level, job satisfaction, and task performance especially in South Korean organizational context. In addition to role of burnout, findings should prove helpful in improving job satisfaction and task performance. The authors provide implications and limitations of the findings.

This study aimed to determine the mediating role of competency (professional competency, technical competency, and core competency) between training and task performance in pharmacists. Questionnaire was the tool of collecting data from a sample of (210) pharmacists. The results of the study indicated that there is a positive effect of training on task performance. Also, there is full effect of the two mediator variables (professional competency; technical competency) and partial effect of the one mediator variable (core competency) on the relationship between independent and dependent variables.

The relationship between trust and task performance in virtual teams is well established. Currently, studies examine key antecedent to trust in groups, the perceived ability of other group members. While it has been shown that perceived ability of teammates contributes to trust, little is known about how the perceptions of ability are formed in virtual teams. In this study, teams performed a decision-making task in a synchronous computer-mediated communication environment. As teams were limited to verbal communication, the authors examined the relationship between participant ability and verbal communication amount, as well as team member perceptions of their partners’ ability based on the amount of participation. The results show that participants who perceive themselves to have higher ability communicate more, whereas those who speak more are rated by their teammates to have lower ability. Based on the results, post hoc analysis explored the relationship between reduced participation and perceived ability.

PurposeDrawing on the dynamic model of ability, motivation, opportunity (AMO) for human resource research, this study aims to examine how organizational system-level (i.e. the high-performance work system (HPWS)) and individual-level AMO affect employees' performance. Specifically, this paper proposes that employee task performance is resultant from the integration of system- and individual-level AMO factors with employee contextual performance.Design/methodology/approachA survey design is employed with data collected from 250 employees working in New Zealand's service sector.FindingsThis study finds both organizational system (HPWS) and individual AMO dimensions have positive associations with employees' performance. At the system level, the supportive role played by contextual performance is highlighted with pro-social behaviors fully mediating the relationship between the HPWS and task performance. At the individual level, contextual performance is found to partially mediate the relationship between ability and task performance and fully mediate the relationship between motivation and task performance. Opportunity, on the other hand, is significantly associated with task but not contextual performance.Originality/valueIn acknowledging there are a plurality of factors that impact performance, this study enriches our understanding of AMO's influence in the context of people management.

Thermal factors not only affect the thermal comfort sensation of occupants, but also affect their arousal level, productivity, and health. Therefore, it is necessary to control thermal factors appropriately. In this study, we aim to design a thermal environment that improves both the arousal level and thermal comfort of the occupants. To this end, we investigated the relationships between the physiological indices, subjective evaluation values, and task performance under several conditions of changes in the indoor ambient temperature. In particular, we asked subjects to perform a mathematical task and subjective evaluation related to their thermal comfort sensation and drowsiness levels. Simultaneously, we measured their physiological parameters, such as skin temperature, respiration rate, electroencephalography, and electrocardiography, continuously. We investigated the relationship between the comfort sensation and drowsiness level of occupants, and the physiological indices. From the results, it was confirmed that changes in the indoor ambient temperature can improve both the thermal comfort and the arousal levels of occupants. Moreover, we proposed the evaluation indices of the thermal comfort and the drowsiness level of occupants using physiological indices.

Abstract Background and Purpose. The Functional Standing Balance (FSB) Scale was designed to obtain measurements of standing balance and to identify the problems typically faced by people with stroke. The purpose of this study was to investigate the validity of measurements obtained with the FSB Scale for use in the acute and chronic phases of stroke by comparing the measurements obtained with the FSB Scale with those obtained for postural sway and lateral symmetry by use of a force platform. Subjects and Methods. Measurements were obtained for 26 people with recent strokes (ie, strokes within 3 weeks of data collection) and for 28 people with long-standing strokes (ie, strokes of 6 months' duration or older). The FSB Scale consists of 3 components: weight distribution, balance without movement, and balance with movement. Measurements of balance performance were compared with measurements of anteroposterior and lateral sway velocity obtained on a force platform. The weight distribution on 2 digital scales was compared with the lateral symmetry measured on the force platform. Results. The highest correlations were found between the FSB Scale balance measurements and the measurements of anteroposterior sway velocity obtained on the force platform with feet apart and eyes open. The correlations (r) were −.68 and −.67 for the group with recent strokes and −.74 and −.91 for the group with long-standing strokes. The correlations (r) between weight distribution measured on the digital scales and lateral symmetry measured on the force platform were .44 for the group with recent strokes and .52 for the group with long-standing strokes. Discussion and Conclusion. The subjects whose results on the FSB Scale were poor had higher sway velocities on the force platform than the subjects whose results on the FSB Scale were good. The results of this study suggest that the FSB Scale provides the same kind of information as that obtained for sway velocity and lateral symmetry as measured with the use of force platforms in both patients with recent strokes and patients with long-standing strokes.
