Job stress,coping strategies,and burnout among hotel industry supervisors in Taiwan

The complex and changing environment of the hospitality industry presents a never ending array of stimuli, pressures and demands which can become sources of stress for hotel supervisors. A focus on the identification of current and potential stressors in organizations, and the development of strategies which individuals and management may use to manage and reduce stress effectively, is imperative. This study is to investigate the perceived level of stress of hotel supervisors, to establish frequency of the use of various coping strategies, and to determine the burnout rate. This study also empirically examines the relationships among stress, coping strategies, and job burnout. A convenient sample of hotel supervisors of large hotels in Taiwan was selected. The return of 298 questionnaires represented 74.5% of the total supervisors surveyed. The study findings suggest that the major job stress of hotel supervisors originates from task characteristic and workload. Moreover, a direct action coping strategy may allow one to perceive the situations as opportunities and may, in turn, contribute to reduce job stress. Furthermore, hotel supervisors experience a lower level of burnout if they apply more direct action strategies in coping with the pressures of their job. The results of this study can be used as part of guidelines including what should be considered to reduce job stress and burnout in the work environment.     

Linking job insecurity to well-being and organizational attitudes in Belgian workers: the role of security expectations and fairness

The aim of this study was to investigate how perceptions of job insecurity and fairness associate with individual well-being (job satisfaction and general health) and organizational attitudes (organizational commitment and turnover intention), under the condition that the psychological contract as perceived by the employee includes a promise on job security, or not. More specifically, we suggest that (H1) job insecurity is negatively related to individual well-being and organizational commitment and positively related to turnover intentions when job security is expected as part of the psychological contract, (H2) that job insecurity is negatively related to fairness perceptions when job security is expected as part of the psychological contract, (H3) that fairness associates positively with individual well-being and organizational commitment and negatively with turnover intentions and (H4) that the association between job insecurity, individual well-being and organizational outcomes is mediated by fairness under the condition that job security is expected as part of the psychological contract. Thus, we propose a model of mediated moderation. Results based on a sample of Belgian employees (N = 559) supported our hypotheses for organizational outcomes. For individual well-being, the mediation framework was not conditional upon a perceived promise of job security as part of the psychological contract. We conclude that employees' perceptions of job insecurity and fairness are important factors in employees' well-being and their attitudes towards the organization. More importantly, these perceptions can in part be shaped by organizational agents such as managers and supervisors. Additionally, the active utilization of the psychological contract in management strategies seems to have favourable results for the fostering of pro-organizational attitudes among employees.

The impact of coding time on the estimation of school effects

Multilevel growth curve models are becoming invaluable in educational research because they model changes in student outcomes efficiently. The coding of the time variable in these models plays a crucial role as illustrated in this study for the case of a three-level quadratic growth curve model. This paper shows clearly how the choice of a time coding affects school effects estimates and their interpretation. A new definition for school effects for growth curve models with random intercepts and slopes is proposed. This study recommends that the choice of a time coding should not only be based on the ease of interpretation and model convergence but also on its consequences on the student status and growth parameter estimates. The current application illustrates that in general the school effects for student growth in well-being and language achievement in secondary school, are greater for student growth than for student status.     

An empirical assessment of the cross-national measurement validity of graded paired comparisons

The popular use of graded paired comparisons in empirical studies assessing consumers’ preferences, and the potential effect of cross-national differences in (extreme) response styles on the quality of graded paired comparison data, supply ample reasons for an empirical verification of the cross-national validity of such scales. Using data from a cross-national margarine brand study including fourteen different nations (N = 4,560), we found sufficient statistical evidence for cross-national bias due to existing cross-national differences in extreme responses. However, the low values reported for effect size measures (intra-class correlation coefficient, R ² value) indicated that the impact of the cross-national bias is marginal. The findings from our study provided empirical support for the hypothesis that graded paired comparison data can be meaningfully compared across nations.     

Issues in the analysis of co-authorship networks

Scientific collaboration is a complex phenomenon that improves the sharing of competences and the production of new scientific knowledge. Social Network Analysis is often used to describe the scientific collaboration patterns defined by co-authorship relationships. Different phases of the analysis of collaboration are related to: data collection, network boundary setting, relational data matrix definition, data analysis and interpretation of results. The aim of this paper is to point out some issues that arise in these different phases, highlighting: (i) the use of local archives versus international bibliographic databases; (ii) the use of different approaches for setting boundaries in a whole-network; (iii) the definition of a co-authorship data matrix (binary and weighted ties) and (iv) the analysis and the interpretation of network measures for co-authorship data. We discuss the different choices that can be made in these phases within an illustrative example on real data which is referred to scientific collaboration among researchers affiliated to an academic institution. In particular, we compare global and actor-level network measures computed from binary and weighted co-authorship networks in different disciplines.
