The dimensionality of self-rated employee performance : an integrated view

This study addresses the debate in the literature regarding the dimensionality of the job performance construct. The sample comprised 647 public servants from a state-based law enforcement organisation. Exploratory and confirmatory factor analyses delineate a four:factor structure, consisting of in-role behaviour, organisational citizenship behaviour directed towards (1) individuals or (2) the organisation, and a distinct latent variable deemed counter-productive work behaviour (CWB). The pattern of correlations among the four performance dimensions and between the performance dimensions and attitudes support the construct and discriminant validity of the four performance dimensions. Further, the .findings propose that CWB is a core, not discretionary, dimension of performance.<br /

Promoting health at work : the relevance of organizational justice

Research focusing on the relationship between organizational justice and health suggests that perceptions of fairness can make significant contributions to employee wellbeing. However studies examining the justice health relationship are only just emerging and there are several areas where further research is required, in particular, the uniqueness of the contributions made by justice and the extent to which the health effects can be explained by linear, non-linear and/or interactional models. The primary aim of the current study was to determine the main, curvilinear and interactive effects of job characteristics and organizational justice perceptions on psychological wellbeing and job satisfaction. Job characteristics were measured using the Demand-Control Support (DCS) model (Karasek &amp; Theorell, 1990), while Colquitt\u27s (2001) four justice dimensions (distributive, procedural, interpersonal and informational) were used to assess organizational justice. Hierarchical regression analyses found that in relation to psychological wellbeing, perceptions of justice did not add to the explanatory power of the DCS model. In contrast, organizational justice did account for unique variance in job satisfaction, the second measure of employee wellbeing. The results supported direct linear relationships between the psychosocial working conditions and the outcome measures. The implications of the results of this study, especially in terms of how working conditions should be managed in order to promote health, are discussed. Notably, the findings from the current study indicate that in addition to traditional job stressors, health promotion strategies should focus on perceptions of organizational justice and their relationships with health.<br /

Frequency and phase locking of laser cavity solitons

Self-localized states or dissipative solitons have the freedom of translation in systems with a homogeneous background. When compared to cavity solitons in coherently driven nonlinear optical systems, laser cavity solitons have the additional freedom of the optical phase. We explore the consequences of this additional Goldstone mode and analyse experimentally and numerically frequency and phase locking of laser cavity solitons in a vertical-cavity surface-emitting laser with frequency-selective feedback. Due to growth-related variations of the cavity resonance, the translational symmetry is usually broken in real devices. Pinning to different defects means that separate laser cavity solitons have different frequencies and are mutually incoherent. If two solitons are close to each other, however, their interaction leads to synchronization due to phase and frequency locking with strong similarities to the Adler-scenario of coupled oscillators

A step toward a common measure of organizational fairness

The paper examines dimensions of organizational justice construct in a public sector context, utilizing an organizational justice measure developed and validated by Colquitt (2001). The present study substantiates the existing claims about the independence of interactional justice and the division of interactional justice into interpersonal and informational justice. The present investigation also contributes to the justice literature by providing evidence of a new factor, which is called procedural voice justice to reflect the possible association with the concept of voice effect. Although voice has been examined extensively in the justice research as an antecedent of procedural justice, little is known about if and how voice might integrate into procedural justice construct. The study proposes that future justice research further investigate dimensionality of organisational justice and aspire to developing a common measure of the justice construct.<br /

Abating the consequences of managerialism on the forgotten employees : the issues of support, control, coping and pay

With the widespread and continuing adoption of managerialism in the public sector, ignoring the impact of change on employees could prevent managerialism from achieving its goals. Subsequently, this study investigates the efficacy of an augmented demand-control-support (D-C-S) model in predicting three of the key employee outcomes in the context of organizational change&mdash;psychological health, job satisfaction, and organizational commitment. Analyses of a survey of 207 employees in the Australian public sector, a sector that has undergone, and continues to undergo, substantial change toward managerialism, found that the augmented D-C-S model explained a significant proportion of the employee outcomes in the public sector context. The most important variables were work-based social support and job control. Coping style and perceptions of work conditions, such as pay, were also significant. The augmented D-C-S model provides a useful, proven tool for managers operating within the contemporary public sector.<br /

Assessing the strain experienced by managers and professional Australian footballers using an augmented job strain model

Generic models of job stress, such as the Job Strain Model (JSM), have recently been criticised for focusing on a small number of general work characteristics while ignoring those that are occupation-specific (Sparks & Cooper, 1999). However this criticism is based on limited research that has not examined the relative influence of all three dimensions of the JSM - job demand, job control and social support - and job-specific stressors. The JSM is the most commonly used model underpinning large-scale occupational stress research (Fox, Dwyer, & Ganster, 1993) and is regarded as the most influential model in the research on the psycho-social work environment, stress and disease in recent times (Kristensen, 1995). This thesis addresses the lack of information on the relative influence of the JSM and job-specific stressors by assessing the capacity of an augmented JSM to predict the strain experienced by managers and professional Australian footballers. The augmented JSM consisted of job-specific stressors in addition to the generic components of the model. Managers and professional Australian footballers represent two very different occupational groups. While the day-today roles of a manager include planning, organising, monitoring and controlling (Carroll & Gillen, 1987), the working life of a professional Australian footballer revolves around preparing for and playing football (Shanahan, 1998). It was expected that the large differences in the work undertaken by managers and professional Australian footballers would maximise the opportunities for identifying job-specific stressors and measuring the extent that these vary from one group to the next. The large disparity between managers and professional footballers was also used to assess the cross-occupational versatility of the JSM when it had been augmented by job-specific stressors. This thesis consisted of three major studies. Study One involved a survey of Australian managers, while studies Two and Three focused on professional Australian footballers. The latter group was under-represented in the literature, and as a result of the lack of information on the stressors commonly experienced by this group, an in-depth qualitative study was undertaken in Study Two. The results from Study Two then informed the survey of professional footballers that was conducted in Study Three. Contrary to previous research examining the relative influence of generic and job-specific stressors, the results only provided moderate support for augmenting the JSM with job-specific stressors. Instead of supporting the versatility of the augmented JSM, the overall findings reinforced the broad relevance of the original JSM. Of the four health outcomes measured in Studies One and Three, there was only one - the psychological health of professional Australian footballers - where the proportion of total variance explained by job-specific stressors exceeded 13%. Despite the generally strong performance of the JSM across the two occupational groups, the importance of demand, control and support diminished when examining the less conventional occupation of professional football. The generic model was too narrow to capture the highly specific work characteristics that are important for this occupational group and, as a result, the job-specific stressors explained significantly more of the strain over and above that already provided by the generic model. These findings indicate that when investigating the stressors experienced by conventional occupational groups such as managers, the large amount resources required to identify job-specific stressors are unlikely to be cost-effective. In contrast, the influence of the more situation specific stressors is significantly greater in unconventional occupations and thus the benefits of identifying these non-generic stressors are more likely to outweigh the costs. Studies One and Three identified strong connections between job-specific stressors and important characteristics of the occupation being studied. These connections were consistent with previous research and suggest that before attempting to identify job-specific stressors, researchers need to first become familiar with the nature and context of the occupation. The final issue addressed in this thesis was the role of work and non-work support. The findings indicate that the support provided by supervisors and colleagues was a significant predictor of wellbeing for both managers and professional footballers. In contrast, the level of explained strain accounted for by non-work support was not significant. These results indicate that when developing strategies to protect and enhance employee well-being, particular attention should be given to monitoring and, where necessary, boosting the effectiveness of work-based support. The findings from this thesis have been fed back to the management and sporting communities via conference presentations and peer-reviewed journals (refer pp 220-221). All three studies have been presented at national and international conferences and, overall, were well received by participants. Similarly, the methods, results and major findings arising from Studies One and Two have been critiqued by anonymous reviewers from two international journals. These papers have been accepted for publication in 2001 and 2002 and feedback from the reviewers indicates that the findings represent a significant and unique contribution to the literature. The results of Study Three are currently under review by a sports psychology journal
