Frequent business travel can be a burden for travelers' work and private life. We tested whether preventive coping (the proactive accumulation of resources in advance of potential stressors) makes such trips beneficial despite their potential to be stressful. In a longitudinal three‐wave study, we investigated whether frequent travel relates to an increase or decrease in work–life balance, emotional exhaustion, work engagement, and relationship satisfaction depending on preventive coping. Findings from a sample of 133 frequent business travelers revealed significant indirect effects for emotional exhaustion, work engagement, and relationship satisfaction through work–life balance. Among employees who engaged less in preventive coping, a higher number of business trips was related to a decrease in work–life balance, which, in turn, was related to more emotional exhaustion, less work engagement, and lower relationship satisfaction. Among those who reported higher preventive coping, we found opposing indirect effects: Frequent travel was related to an increase in work–life balance and, in turn, to less emotional exhaustion, more work engagement, and higher relationship satisfaction. These findings advance our knowledge in the field of business travel, future‐oriented coping, and work–life balance. They highlight that travelers and their organizations should resort to preventive coping to make frequent travel more beneficial.  相似文献

This study explores how autonomy at the individual and the group levels directly affect group cohesiveness, and how they indirectly influence group effectiveness. Hypotheses suggesting that individual and group autonomy will be oppositely related to cohesiveness are supported in data collected from a large sample of work groups in two separate organizations. Also supported are hypotheses suggesting a group cohesiveness/group performance orientation interaction as a mediator of the relationships between autonomy at both levels and group effectiveness. The findings highlight the importance of considering autonomy at both individual and group levels simultaneously when designing work groups that incorporate autonomy.

The current paper investigated the longitudinal effects of mass career customization (MCC) on job attitudes and objective career outcomes of employees in a professional service firm in the Netherlands. On the basis of theory on individualization of career trajectories, it was expected that the possibility for employees to customize their careers would be positively related to their job attitudes and subsequent objective career success, as indicated by their levels of affective commitment, work engagement, and received salary and bonuses. However, these effects were expected to occur primarily under the combination of high manager support for implementation of career customization and, on the basis of lifespan theory, older workers, as customization fulfills their increased heterogeneous career preferences. A three‐wave longitudinal study largely showed support for the study hypotheses; the relation between MCC use and work engagement and subsequent career success was stronger for older workers who received support for MCC, whereas the relation between MCC use and commitment was negative for older workers who received low support. The study shows the benefits of career customization in organizations by showing the conditions under which these benefits will manifest. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

This field study addressed the relationship between age and work outcomes by investigating the effects of two potential moderators of age–work outcome relations: self-efficacy and perceptions of tool design effectiveness, while controlling for job tenure, job demands, and gender. Findings revealed that job-focused self-efficacy beliefs moderated the relationship between age and absenteeism, while tool design moderated the relationship between age and performance. Self-efficacy and tool design both had direct positive main effects on job satisfaction. Implications for research on age and constructive work force management are discussed.  相似文献

Little research to date has focused on understanding employee motivation to share and hide knowledge. Using self‐determination theory, we tested the premise that knowledge sharing and hiding might be differentially motivated and that work design characteristics might influence the motivation to share knowledge with colleagues. In a panel survey of Australian knowledge workers and in a Chinese knowledge‐intensive organization, we asked knowledge workers, using time‐lagged designs, about perceptions of work design, motivation to share knowledge, and self‐reported knowledge sharing and hiding behaviors. Results, largely replicated across both samples, indicated that cognitive job demands and job autonomy were positively related to future reports of knowledge‐sharing frequency and usefulness via autonomous motivation to share knowledge. Unexpectedly, task interdependence was positively related to the three forms of knowledge hiding (evasive and rationalized hiding, and playing dumb) via external regulation to share knowledge. Implications for the design of jobs that motivate knowledge sharing and demotivate knowledge hiding are discussed.  相似文献

This study is an attempt to replicate and extend recent findings concerning the moderating effect of employment commitment on the psychological impact of unemployment. It was carried out in a highly educated population and employed Protestant work ethic endorsement (PWE) and work involvement (WINV) as indicators of commitment to work. Evidence was collected by questionnaires from 432 individuals who had been unemployed and again, six months later, from most of the same individuals. Cross-sectional and longitudinal analysis shows that individuals with high WINV were likely to suffer more from unemployment and to gain more from finding employment than low work-involved individuals. PWE, on the other hand, did not moderate the relationship between employment status and psychological state.  相似文献

This paper examines the key role that individual work reflection plays in facilitating individuals' leadership in teams. Consistent with the functional perspective on leadership, we argue that individual work reflection allows individuals to better understand their team's needs, and therefore enact higher levels of task-, relational-, and change-oriented leadership behaviors and be more effective leaders in their teams. We first conducted a series of measure development studies to validate a measure of individual work reflection comprising four dimensions of reflection at work: goals-, methods-, relationships-, and self-focused reflection. Then, across two independent studies assessing individuals in self-managing teams over time, we found support for our theoretical model linking individual work reflection to peer-rated leadership behaviors (Main Studies 1 and 2) and leadership effectiveness (Main Study 2). In further support of our theorizing, Main Study 2 also indicates that individual work reflection shapes leadership behaviors and effectiveness via understanding the team's needs, beyond a wide range of related constructs (e.g., feedback seeking, mindfulness, and rumination), as well as commonly studied predictors of leadership behaviors (i.e., the Big Five). Our theory and empirical findings help advance insights on the role of individual work reflection in improving leadership outcomes in organizations.  相似文献

Although researchers have often found positive relationships between organizational citizenship behavior (OCB) and performance rating, very few studies have scrutinized the team contexts in which such relationships exist. This study examines how OCB influences job performance ratings within different team cultures, as measured by team collectivism and individualism. On the basis of multilevel data collected from 81 teams working at a multinational bank in Hong Kong, team collectivism and individualism were found to moderate the OCB–performance rating relationship such that OCB targeting individuals improved rated performance in highly collectivistic teams only, whereas only organizational OCB produced a significant improvement in highly individualistic teams. The implications of these findings and directions for future research directions are discussed here. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

In this article, we discuss different types of cultural diversity recomposition that can occur in monoculture work groups. Several direct effect propositions are set forth about the impact of cultural diversity recomposition type on monoculture group effectiveness, as are several moderating effect propositions. We identify potential moderators that have not been explored in prior research and discuss the implications that each has for organizational behavior and practice. We then discuss some implications for future research. We conclude this article with a call for establishing a research agenda that will guide our thinking as we explore this topic in more depth.

We conducted a longitudinal field experiment to examine whether sociometric and ability-based assignment methods have different effects on multiple outcomes. We assigned subjects (N = 258) to sociometric or ability-based conditions, and assembled them into three-person workgroups. Subjects in the sociometric condition chose their own workgroup members; we assigned subjects in the ability-based condition to groups on the basis of ability. The results show that sociometric workgroups report higher levels of communication, coordination, peer ratings, group cohesion, and job satisfaction than workgroups in the ability-based condition. In addition, the results indicate that organizational forces tended to equalize the influence of ability on performance.  相似文献

Recent research suggests that the occurrence of operational problems in advanced manufacturing technology (AMT) places stressful demands on operators. Applying Karasek's demand–control model, we predict that two properties of operational problems, namely technological uncertainty and abstractness, interact with timing and method control to predict operator strain. The results failed to confirm ordinal effects for timing or method control, but showed a dis-ordinal (crossover) interaction for timing control. While these findings provide little support for the demand–control model, they suggest that two new processes, namely ‘traction–distraction’ and ‘passivity–challenge’, are critical to understanding the nature of the relationship between operational problems and operator strain in AMT systems. We describe these processes and examine the implications for future research. © 1997 John Wiley & Sons, Ltd.  相似文献

The present study examines the impact of behavioral control on the experience of work strain under conditions of work overload. Extending experimental laboratory findings that suggest that control can lessen the impact of aversive stimuli on psychological and physiological strain responses, we hypothesized an interaction between control and workload such that the effects of high demands on strain would be less if the worker had behavioral control over the task. This hypothesis is also consistent with Karasek's job demands-job decision latitude model of work strain and health. The hypothesis was tested in a laboratory experiment in which 125 subjects worked on a mail sorting task with either a high or moderate level of workload and either a high or low level of behavioral control. Strain responses were assessed with measures of job satisfaction, anxiety, and physiological arousal. The hypothesis was only partially supported in that high control lessened the impact that work overload had on anxiety. While not fully supportive of the model, the results are seen as conservative given the constraints on the manipulation of work overload inherent in the laboratory environment.  相似文献

Increased job complexity and autonomy have often been associated with improved performance in work groups. This study examines the mediating effect of group cohesiveness. The moderating effects of individualism/collectivism on the relationship between job characteristics (both complexity and autonomy) and cohesiveness are also tested. The sample consists of 381 teams drawn from the Hong Kong and U.S. branches of an international bank. The findings indicate that an increase in job complexity and/or task autonomy will increase group cohesiveness, which subsequently translates to better performance. The positive effects of job complexity and autonomy on group cohesiveness are also found to be more prominent for individualistic rather than collectivistic work groups. The theoretical implications of the results and the limitations of the study are also discussed. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

This paper introduces a theoretical framework to guide research into the psychological effects of advanced manufacturing technology (AMT) on shopfloor operators. The framework has two main aspects. First, based on the emerging literature on the job content implications of AMT, it identifies four key constructs, namely: control, cognitive demand, production responsibility and social interaction. Second, by drawing on the more established job design, stress and related literatures, it predicts how these independent variables differentially affect system performance, job-related strain and job satisfaction. The wider implications and limitations of the theoretical framework are discussed.  相似文献

PURPOSE: The Federal Highway Administration (FHWA) proposed guidelines for highway design to increase the safe driving ability of older drivers; however, little empirical evidence exists to support the effectiveness of these guidelines. The purpose of this study was to investigate the effects of implementing these guidelines (in 4 pairs of intersections) on safe driving performance of older and younger drivers using a high-fidelity driving simulator. DESIGN AND METHODS: We replicated four intersection pairs (improved versus unimproved) in a high-fidelity, virtual reality driving simulator. Simulator scenarios were created from actual road locations, replicating road geometrics and traffic control devices. The simulator's controls were integrated with an actual vehicle to make the driving experience as realistic as possible. Kinematic measures were obtained from the simulator in conjunction with driving errors recorded by trained driving evaluators sitting in the cab of the car. Thirty-nine subjects, 19 younger and 20 older adults, participated in the study. RESULTS: For the kinematic data we found greater lateral control, as indicated by significantly smaller maximum yaw during the turn phase, at all of the improved intersections when compared to the unimproved intersections. We found some significant age differences, but mostly in only one of the intersection-pairs. For the behavioral data, there were significant differences in driving errors between improved and unimproved intersections in two intersection-pairs; however, there were no significant differences in driving errors between the older and younger drivers. IMPLICATIONS: The findings suggest that both young and older drivers may benefit from roadways with safety features recommended by the FHWA guidelines as indicated by the increased lateral control of the vehicle when negotiating these intersections. These findings generate critical information for those involved in the design of roadway systems.  相似文献

OBJECTIVE: To test the effectiveness of the FHWA guidelines for intersection design. METHODS: In an experimental design we used kinematics measures from an instrumented vehicle and behavioral (error) data collected during on-road evaluations to quantify the effects of improved versus unimproved intersections (turn phase) and to determine if these intersections were safer (vehicular stability and driver confidence) for both older (65-85 years) and younger (25 -45) drivers. We analyzed kinematics data with a 2 x 2 repeated measures ANOVA and behavioral data (driving errors yes, no) with Wilcoxon sign rank test (within subject variable: intersection improved vs. unimproved) and Wilcoxon rank sum test (between subject variable: age, younger vs. older driver). RESULTS: Kinematics measures (turn phase), showed three maneuvers had statistically significantly lesser side forces (measured by lateral acceleration and combined acceleration) for the improved conditions, and four maneuvers had statistically significantly greater, yet appropriate, speeds for the improved conditions. Lesser side forces indicated improved lateral stability and increased speed indicated greater confidence. Drivers made fewer errors on two of the improved intersections; but across all maneuvers, older drivers appeared to make fewer errors on the improved intersections. CONCLUSIONS: This study brings empirical intersection design and safety information for engineers and city planners to consider as they plan and develop intersections. Future researchers may want to use the conceptual and analytical framework of this study to determine the effectiveness of other FHWA guidelines. Given that these intersection design guidelines benefit younger and older drivers alike, plausible policy-making opportunities are opened in the design of safe roadway systems, to benefit the broad spectrum of adult drivers.  相似文献

This study is based on three premises: (a) Leadership style affects the level of concern for subordinate safety; (b) Concern for safety, operationalized with supervisory practices, provides the source for safety climate perceptions; and (c) Safety priority as assigned by higher superiors influences supervisory safety practice independently of leadership style. Assigned safety priority was expected to moderate the relationship between leadership style and injury rate in organizational subunits, with safety climate mediating this leadership–injury relationship due to its demonstrable effect on safety behavior. A within‐group split‐sample analysis of 42 work groups, coupled with prospective design, indicated that transformational and constructive leadership predicted injury rate, while corrective leadership provided indirect, conditional prediction. Leadership effects were moderated by assigned safety priorities and mediated by commensurate safety‐climate variables. The results suggest that transformational and transactional leadership provide complementary modes of (mediated and moderated) influence on safety behavior of group members.

This study is anchored in a contractor company providing well services for platform drilling on the Norwegian (NCS) and the UK Continental Shelves (UKCS). The research project has as its point of departure the potential influences of group level characteristics, structural work factors, trust, and safety behaviour on safety performance. Do perceptions and performance differ across Shelves? Are “nomadic” groups or employees that have more unpredictable shift rotations more exposed to accidents than others? Is high trust and sound safety behaviour enhancing good safety performance? The results are based on questionnaire data from two samples of personnel distributed across three installations on the UKCS and nine on the NCS with a response rate of 67%: N = 170 (UKCS) and N = 621 (NCS). In addition, two focus group interviews were held in each country, with 15 participants in each. The results show that our model makes sense. Shelf shows a significant influence on safety performance in all but the final stage in our five-step logistic regression model, indicating that the effect may be mediated by safety compliance and safety participation. Installations and different work teams have different exposure and structural work factors matter significantly. Somewhat counter-intuitively, employees who have a “nomadic” status and who hold the least regular shift rotations appear to have a lower risk of being involved in incidents. High trust in workmates buffers against incident involvement and the same applies for high safety compliance. The results, challenges and implications for research and safety practitioners are discussed.  相似文献

Organizational scholars have recently shifted their attention to examining organizational citizenship behavior (OCB) as a group-level phenomenon. Adopting the input-mediator-outcome model of group performance, we examined antecedents and intermediate processes that predict group-level OCB (GOCB) in small work groups. The results, based on data from 62 work groups representing a variety of industries, revealed that demographic faultlines based on relation-oriented attributes (gender, age, and race) and a task-related attribute (tenure) had differentiated relationships with task and relationship conflict, which mediated the relationships between faultlines and group outcomes (GOCB and group performance). Both task and relationship conflict were negative predictors of group performance. However, task conflict increased GOCB, whereas relationship conflict decreased it. The present study offers evidence of the relationship between demographic faultlines and various group processes and outcome variables in natural work groups.
