This research-based article presents the results of a study examining job satisfaction among social workers in public social services in Crete, Greece. It focuses on their overall job satisfaction, as well as on their satisfaction or dissatisfaction with intrinsic, extrinsic and organisational work aspects. The results of this study suggest that while respondents experienced a quite high level of overall satisfaction with their job, other indicators of job satisfaction showed that the level of job satisfaction was not so high. The main sources of respondents’ satisfaction were intrinsic work aspects while the main sources of dissatisfaction were organisational and extrinsic work aspects. Respondents’ job satisfaction was found to be significantly correlated with: the years of unemployment before respondents first worked as social workers, the number of social workers working in the organisation, and their intention to leave or change their present job.
This paper presents a decision support methodology for strategic planning in tramp and industrial shipping. The proposed methodology combines simulation and optimization, where a Monte Carlo simulation framework is built around an optimization-based decision support system for short-term routing and scheduling. The simulation proceeds by considering a series of short-term routing and scheduling problems using a rolling horizon principle where information is revealed as time goes by. The approach is flexible in the sense that it can easily be configured to provide decision support for a wide range of strategic planning problems, such as fleet size and mix problems, analysis of long-term contracts and contract terms. The methodology is tested on a real case for a major Norwegian shipping company. The methodology provided valuable decision support on important strategic planning problems for the shipping company. 相似文献
