This study examines critical organisational factors and work scheduling in railway freight operators to understand how job-related factors are related to fatigue, health and social well-being. A 148-item questionnaire was developed and distributed to a sample of 276 locomotive engineers and conductors working for the U.S. Operations of a North American Railway. One hundred and twenty-five questionnaires were returned, which was a response rate of 45.3%. Structural equation modeling was performed to identify the relationships between the examined factors. The analytical results of this study indicate that organisational factors and the scheduling system could not be distinguished as two separate factors. The scheduling system is not just the practice of assigning locomotive crewmen to trains, but it is a function tightly connected with other organisational factors. Social Well-Being is an important mediator between Scheduling and Fatigue. Finally, the study revealed a strong relationship between fatigue and health complaints. 相似文献

Investigated the attitudinal impacts of receiving formal performance appraisal feedback. Based on the suggestion that the feedback that one is "satisfactory" will be disconfirming for many feedback recipients, it was hypothesized that attitudes toward the performance appraisal systems and organizational commitment will decrease and remain lower for those receiving satisfactory ratings, whereas the attitudes of those receiving higher appraisal ratings will remain unchanged. The hypotheses were tested on panels of management and nonmanagement employees (the latter receiving new appraisals 12 mo after their managers) in 2 federal agencies over a 30-mo period using perceived and actual performance ratings. There was a significant and stable drop in the organizational commitment of satisfactory employees after the introduction of formal appraisals, with mixed results for attitudes toward the appraisal system. Findings suggest that potentially negative consequences of implicitly comparative formal performance appraisals can occur for those performing at a satisfactory, but not outstanding, level.

Using an online survey, value management practice by construction professionals in South Africa is investigated. Opinions were sought from architects, engineers, quantity surveyors, and project and construction managers. An objective is to test the UK‐based assertion of Kelly et al. (2004) that VM is an established service with commonly understood tools, techniques and styles. While awareness of VM is reasonably prevalent among the professions, it is far less so among architects. Actual practice of VM is considerably less extensive, with the architects reporting the lowest level of usage. Much higher levels of awareness and practice could have been expected. Knowledge of VM techniques appears dated, and membership of VM associations is rare. Usage of VM is invariably founded on a cost‐minimization driver. Little attempt is made to benchmark VM activities against international standards nor is a standard methodology employed. Value management is not generally used to facilitate the client briefing process. The findings are important given the increasing globalization of construction services, especially the growth of international ties between built environment professionals. It is recommended that the professional associations that promote the activities of the professions in SA should organize suitable refresher skills and training opportunities in VM. 相似文献
