Incentives and cooperation: the joint effects of task and reward interdependence on group performance

We examine the joint effects of task interdependence and reward interdependence on group behavior and performance. We develop a model that predicts that task and reward interdependence will interact to increase performance, and present results of a laboratory experiment that confirms our prediction. We explore the efficacy of group reward systems for different task designs, and the relationship between cooperation and performance. We confirm earlier results on the weakness of the free-rider effect in small face-to-face groups. We also find, surprisingly, that while reward interdependence is important to performance, task interdependence, but not reward interdependence, drives observed cooperative behavior. This last result suggests caution in interpreting the efficacy of changes in the design of work. Such changes, if unaccompanied by changes in the design of the reward system, are likely to appear successful in terms of observed cooperation, but may not enhance performance. © 1997 by John Wiley & Sons, Ltd.     

Distinct effects of intrinsic motivation and extrinsic rewards on radical and incremental creativity: The moderating role of goal orientations

Previous studies have investigated the role of intrinsic motivation and extrinsic rewards in enhancing employee creativity. However, the possibility that these motivational factors affect the creativity of different types remains largely unexplored, particularly in the organizational settings. Moreover, the potential that personality traits may moderate the function of these motivational factors toward creativity is another underresearched area. By drawing on the person–situation interaction perspective, we propose that both intrinsic motivation and extrinsic rewards predict creativity but of different types. Thus, we diverge from the view that creativity is a uniform criterion domain by adopting the distinction between radical and incremental creativity. Our empirical analysis of 220 independent employee–supervisor dyads confirmed that intrinsic motivation and extrinsic rewards predict radical and incremental creativity, respectively. Moreover, the effects of intrinsic motivation on radical and incremental creativity are more positive for employees with higher learning goal orientation. By contrast, the effect of extrinsic rewards on incremental creativity is more positive for employees with higher performance goal orientation. This study offers elaborate and nuanced perspectives and insights into the role of different motivational processes in the development of different types of creativity.     

Differential effects of strain on two forms of work performance: individual employee sales and creativity

In this research, we develop and test a model of the links between psychological strain (subjective experiences of feeling conflict and tension) and work performance. Our model includes two types of strain (work strain and home strain) and two forms of work performance (quantity of individual sales performance and creativity). Thus we acknowledge the importance of work and non‐work sources of strain as well as the multidimensional nature of work performance. We test the proposed relationships with data collected over six months from a field sample of 195 hair salon stylists (personal service workers who interact directly with customers and provide services directly to individuals and not to other firms). Results demonstrate a positive relation between work strain and individual employee sales performance and a negative relation between home strain and employee creativity at work. Leader–member exchange moderated the effects of work strain and home strain on creativity. We discuss findings and implications, emphasizing multiple roles, the importance of differentiating types of strain, and the multidimensionality of work performance. We conclude by suggesting that strain may be particularly relevant to work performance of employees in jobs like those in our sample which are characterized by high social interdependence and low task interdependence.

Multilevel outcomes of creativity in organizations: An integrative review and agenda for future research

Employee creativity is critical for an organization's innovativeness and survival in today's competitive business environment. As such, scholars have devoted significant attention to the predictors of employee creativity, seeking to understand how to best increase employees' creative output. However, employee creativity may not always translate into organizational innovation and performance. In fact, employee creativity may result in various outcomes for creative individuals, their coworkers, teams, and organizations. While there have been several integrative reviews on the antecedents of creativity, an in-depth review of the outcomes of creativity is still needed to gain a holistic understanding of the benefits and costs of employee creativity and identify fruitful areas for future research. Thus, we aim to provide a comprehensive multilevel examination of the theories, methods, and creativity-related constructs used to examine the outcomes of creativity. We also provide several theoretical and empirical opportunities for future research. This review may provide managers with knowledge of the pros and cons of employee creativity, enabling them to make informed decisions on how to better manage employee creativity.     

Why seeking feedback from diverse sources may not be sufficient for stimulating creativity: The role of performance dynamism and creative time pressure

We explore how the impact of seeking feedback from different sources (i.e., feedback source variety) on employee creativity is shaped by perceptions of the work environment. Specifically, we argue that two contextual factors, namely, performance dynamism (Study 1) and creative time pressure (Study 2), moderate the relationship between feedback source variety and creativity such that under conditions of high performance dynamism and low creative time pressure, individuals benefit from diverse feedback information. In Study 1 (N = 1,031), the results showed that under conditions of high performance dynamism, the relationship between feedback source variety and self‐reported creativity was nonlinear, with employee creativity exponentially increasing as a function of feedback source variety. Similarly, in Study 2 (N = 181), we found that under conditions of low creative time pressure, the relationship between feedback source variety and employee creativity was nonlinear, with supervisor‐rated creative performance exponentially increasing at higher levels of feedback source variety. Such results highlight that the relationship between feedback source variety and creative performance is affected by the perceptions of the work environment in which feedback is sought.     

Rewards and employee creative performance: Moderating effects of creative self‐efficacy,reward importance,and locus of control

The effects of extrinsic rewards on creative performance have been controversial, and scholars have called for the examination of the boundary conditions of such effects. Drawing upon expectancy theory, we attend to both reinforcement and self‐determination pathways that reveal the informational and controlling functions of creativity‐related extrinsic rewards. We further identify the individual dispositions that moderate these two pathways. Specifically, we propose that extrinsic rewards for creativity positively predict creative performance only when employees have high creative self‐efficacy and regard such rewards as important. We likewise propose that extrinsic rewards positively affect the intrinsic motivation of employees with an internal locus of control, thus enhancing their creative performance. Results based on a sample of 181 employee–supervisor dyads largely supported these expectations. The current analysis enriches the creativity literature by combining different perspectives in a coherent framework, by demonstrating the positive effects of extrinsic rewards on intrinsic motivation, and by demonstrating that the rewards–creativity relationship varies across employees depending on their individual differences.

Task type as a moderator of positive/negative feedback effects on motivation and performance: A regulatory focus perspective

Applying Higgins' regulatory focus theory, we hypothesized that the effect of positive/negative feedback on motivation and performance is moderated by task type, which is argued to be an antecedent to situational regulatory focus (promotion or prevention). Thus, first we demonstrated that some tasks (e.g., tasks requiring creativity) are perceived as promotion tasks, whereas others (e.g., those requiring vigilance and attention to detail) are perceived as prevention tasks. Second, as expected, our tests in two studies of the moderation hypothesis showed that positive feedback increased self‐reported motivation (meta‐analysis across samples: N = 315, d = 0.43) and actual performance (N = 55, d = 0.67) among people working on promotion tasks, relative to negative feedback. Positive feedback, however, decreased motivation (N = 318, d = ?0.33) and performance (N = 55, d = ?0.37) among individuals working on prevention tasks, relative to negative feedback. These findings suggest that (a) performance of different tasks can affect regulatory focus and (b) variability in positive/negative feedback effects can be partially explained by regulatory focus and task type.

Self-leadership and performance outcomes: the mediating influence of self-efficacy

A key foundation of empowering organizations is employee self-leadership. This study examines the effects of self-leadership skills and self-efficacy perceptions on performance. Structural equations modeling determined whether the influence of self-leadership on performance is mediated by self-efficacy perceptions. Results for the sample of 151 respondents indicated self-leadership strategies had a significant effect on self-efficacy evaluations, and self-efficacy directly affected performance. Further, self-efficacy perceptions were found to fully mediate the self-leadership/performance relationship. Theoretical and practical implications are discussed. © 1998 John Wiley & Sons, Ltd.     

Modeling the effects of production pressure on safety performance in construction projects using system dynamics

Introduction: Construction incidents occur due to system failures, not due to a single factor such as unsafe behavior or condition. Therefore, construction safety should be investigated using a systematic view capable of illustrating the complex nature of incidents. Construction projects are also often behind their planned schedule and suffer from various pressures caused by contractual deadlines or clients. Previous studies demonstrated that such pressures negatively affect safety performance; however, the process of how production pressure influences safety performance is not fully investigated. Method: The present research aimed to understand the feedback mechanism of how production pressure interactively affects safety performance and safety-related managerial components in a construction project. Ground theory method (GTM) is used to create a conceptual causal loop diagram that shows the relationship between incident rate and other variables such as labor hour, actual and planned progress, safety climate, rework, and safety training. Moreover, a power plant construction project was used as a case study to practically investigate the conceptual model; a case study is employed to build a System Dynamics (SD) model. The simulation model was then validated using behavior reproduction and sensitivity analysis. Results: The results of the inequality statistics show that the simulation model can be used to forecast trends in the incident rate.     

Risks of faults intrinsic to software languages: Trade-off between design performance and application safety

A lot of products embed software applications carrying out complex functions (e.g. cars, aircrafts, and medical equipments). More and more authority for control is placed on these applications whose failures may lead to accidental loss. Numerous methods have been developed to prevent these failures. These methods apply either to the programs developed or to the design activities. However, the programming or modelling languages used to operationalise the solutions as software applications are rarely questioned. These languages constitute the technology of realization of the program. On one hand, the language features are selected to increase the development performance and to decrease the software application costs. On the other hand, these features may be at the origin of specific types of faults which constitute the intrinsic risks of these languages. Therefore, the choice of a language or of a subset of a language, leads to a decision-making issue of how to deal making safety and performance trade-offs. The first part of the paper analyzes the evolution of the programming languages. We show that these changes were aimed at the convergence of design performance improvement with designed application safety. The introduction of the object-oriented technologies breaks this commonality. They cut the development expenditures but introduce new types of faults. The decision-makers such as the critical software application producers (e.g. the aircraft manufacturers) and the authorities (e.g. the avionics certification authorities) have to deal with this trade-off. These new technologies cannot be just rejected as they are more and more often used in certain domains (e.g. mobile phones, internet applications). The proposed constraint on using them seem to be too restrictive and are not justified. In particular, the safety levels of software programs developed applying these constraints are not assessed. The second part of the paper addresses these questions. It specifies the problem and it proposes a method to estimate the risk of faults in object-oriented programs. Thus, the decision-makers can elaborate rules for using object-oriented languages establishing a trade-off between the wished-for development performance and the required safety levels.     

Impact of authentic leadership on performance: Role of followers' positive psychological capital and relational processes

Authentic leadership has received considerable attention and research support over the past decade. Now the time has come to refine and better understand how it impacts performance. This study investigates the moderating role followers' positive psychological capital (PsyCap) and the mediating role that leader–member exchange (LMX) may play in influencing the relationship between authentic leadership and followers' performance. Specifically, we tested this mediated moderation model with matched data from 794 followers and their immediate leaders. We found that authentic leadership is positively related to LMX and consequently followers' performance, and to a larger degree, among followers who have low rather than high levels of PsyCap. Our discussion highlights the benefits of understanding the roles of relational processes and followers' positive psychological resources involved in the effectiveness of authentic leadership and how they can be practically implemented.

Numerical investigation for pressure mitigation effects of dike on blast wave

The three-dimensional and two-dimensional axisymmetric fluid dynamics simulations were carried out to clarify the blast pressure mitigating effects of dike’s configuration in hemispherical explosion. The simulated peak overpressure on the ground under the hemispherical explosion was compared with the empirical formula by Kingery, and the simulated data were validated. In the analysis, the simplification techniques for the numerical simulation were employed under the following two assumptions. The pressure distribution behind the wide dike was estimated using the axisymmetric flowfield, and the back step model was applied under the small condition for θ, the angle formed by the ground and the line between the explosion core and the dike front corner. From the simulated results, it is clarified that the large θ provided the great reduction of the blast wave pressure at faraway position. In the small θ condition, the conditions of the dike end position and the dike height were significant parameters determining the magnitude of pressure reduction and mitigated area. The pressure reduction at the dike end and mitigated area were predicted numerically, and related to the dike conditions.     

Emotional exhaustion and job performance: The moderating roles of distributive justice and positive affect

In a field study among 241 shop assistants and their 59 supervisors in fashion chain stores in Mainland China and Hong Kong, we found a negative relationship between emotional exhaustion and four indicators of job performance (overall performance, emotional display, OCB‐O, and OCB‐I) when employees perceived high levels of distributive justice in the exchange relationship with the organization, whereas emotional exhaustion was unrelated to any of these performance types when employees perceived low levels of distributive justice. In addition, this negative two‐way interaction effect of emotional exhaustion by distributive justice on job performance was buffered when employees were high on positive affect and intensified when they were low on positive affect. We used the conservation of resources (COR) theory, the attribution model of justice, and the broaden‐and‐build theory of positive emotions to clarify and discuss the moderating roles of distributive justice and positive affect in the relationship between emotional exhaustion and job performance.

Job and industry fit: the effects of age and gender matches on career progress outcomes

Using a sample of 232 MBA alumni, we tested the impact of respondent age, gender, and their interaction on career progress outcomes (managerial level, number of promotions, and salary) and whether age‐ and gender‐type of contexts moderated these relationships. Women's salaries did not increase much with age, whereas men's salaries showed a marked increase with age. We also found a gender × job gender‐type effect on salary, such that women earned somewhat higher salaries in masculine‐typed jobs, while men earned considerably higher salaries in feminine‐typed jobs. In addition, we observed a three‐way interaction between gender, age, and age‐type of industry indicating that younger men received more promotions in old‐typed industries, while younger women received more promotions in young‐typed ones. Results are discussed in light of cognitive matching approaches and status characteristics theory. Copyright © 2004 John Wiley & Sons, Ltd.     

Self‐monitoring and performance appraisal: rating outcomes in project teams

Two studies examined the relationship between ratee self‐monitoring and performance appraisal in project teams using three appraisal sources: self, peer, and supervisor. Study 1, a laboratory study, found that high self‐monitoring (HSM) subjects produced self‐ratings significantly higher than their low self‐monitoring (LSM) counterparts. Further, higher agreement among sources occurred for LSM than for HSM subjects. HSMs' tendency to portray themselves differently to various audiences resulted in less rating convergence across sources. Study 2, employing project teams in five corporations, replicated the convergence finding. Implications for use of various sources of appraisal and for understanding the role of self‐monitoring in performance appraisal are discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Age and work outcomes: The moderating effects of self-efficacy and tool design effectiveness

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.     

Interactive effects of personality and organizational politics on contextual performance

The authors explored the process of evaluating contextual performance in the context of a politically charged atmosphere. They hypothesized that the negative relationship between perceptions of organizational politics and contextual performance is weaker among workers high in three of the Big Five model of personality dimensions—agreeableness, extraversion, and conscientiousness. Data were collected from a matched sample of 540 supervisors and subordinates employed in the private sector. Results indicated that the interaction of politics and the personality dimension of agreeableness explained a significant incremental amount of variance in the interpersonal facilitation facet of contextual performance. These findings demonstrate the need to consider both the situation and the person as antecedents of contextual performance. Copyright © 2002 John Wiley & Sons, Ltd.     

Emotional intelligence and individual performance: evidence of direct and moderated effects

We examined the direct and moderated effects of an ability‐based measure of emotional intelligence (MSCEIT© V2.0) on individual performance in a sample of business undergraduates. Controlling for general mental ability and personality, emotional intelligence explained unique incremental variance in performance ratings on only one of two measures of interpersonal effectiveness (public speaking effectiveness). However, the interaction of emotional intelligence with conscientiousness explained unique incremental variance both in public speaking and group behavior effectiveness, as well as academic performance (cumulative GPA). We conclude that the effects of emotional intelligence on performance are more indirect than direct in nature. Individuals must not only have emotional intelligence, but also must be motivated to use it. Copyright © 2006 John Wiley & Sons, Ltd.
