    Get PDF
    This Research aim‘s to understand the role of servant leadership and organizational climate against ocb with job satisfaction as a mediator. Subject of study the research is permanent workers X University. Data collection methods using a scale that is the scale of servant leadership, organizational climate, job satisfaction and Organizational Citizenship Behavior. The Analysis data conducted using PLS (partial least square) where the process assisted with software smarPLS 3.0. The results of this study indicate job satisfaction significantly influences OCB. Servant leadership and organizational climate significantly influence job satisfaction. Servant leadership significantly influences OCB, however, organizational climate does not affect OCB. Servant leadership can influence OCB through job satisfaction or directly, while organizational climate can affect OCB indirectly so that it is through job satisfaction first. An employer gives positive contribution to the organization voluntarily, because they learn more the habits of his leader who serves as well as possible, and also personal positive perceptions about the quality of organizational life. The role of the two variables will be better if added with high job satisfaction because overall satisfaction with work will increase positive emotions for them and this is will give the impact for employees to encourage positive contributions such as helping colleagues, developing themselves and even involved to increase the organization voluntarily

    Study of the wind speed, rainfall and storm surges for the Scheldt estuary in Belgium

    The Belgian coast and the Scheldt estuary are important for the Belgian economy. Coastal flood risks tend to increase due to climate change. This study was set out to investigate the wind speed, surges and rainfall in the Scheldt estuary. The study explored the changes in mean and extreme winds according to the recent ENSEMBLES climate models and examined the dependency of extremes between surge with wind speed and surge with rainfall. The dependence analysis between surge and wind speed aimed to investigate whether climatic changes in wind speed can be transferred to changes in surge, while the existence of dependence between surge and rainfall would require climate scenarios for rainfall upstream in the Scheldt basin to be correlated with climate scenarios for the downstream surge boundary. A special dependence measure χ, developed by Buishand (1984) and Coles et al (2000) was followed. Data was extracted and processed using Matlab and CDO. The analysis of wind speeds showed that future wind speeds in the estuary (based on the climate models) will remain stable in comparison with the past wind speeds. Also, wind direction will be mainly from 180°-300°, although slight shifts might appear towards more frequent south western winds. From the study of dependency, there was no significant dependency between sea surge at Oostende coast and rainfall at different stations. The definition of significant dependency is strong or conservative. Above all, the extremes events are more or less dependent. While the study has not found significant changes in wind speed and only slight changes in wind direction, it is important to further investigate the impact of these changes on the Scheldt estuary using hydrodynamic models. The assessment of changes in extreme rainfall and sea surge need to be further studied

    Self-efficacy and employee resilience are factors that can affect job insecurity. This study aims to empirically examine the role of self-efficacy and resilience on job insecurity of contract employees at PT. Mega Andalan Kalasan. The population in this study is contract employees in ten units at PT. Mega Andalan Kalasan, who are still actively working, and have worked at least three months. The sample in this study consist of 56 contract employees in the EOP unit of PT. Mega Andalan Kalasan. The sampling technique used is quota sampling, while the data collection method is the self�efficacy scale, resilience scale, and job insecurity scale. Multiple linear regression analysis shows that self-efficacy and resilience have a very significant effect on the job insecurity of contract employees (R = 0,600, p = 0,000). There is a very significant negative relationship between self-efficacy and job insecurity among contract employees, with a correlation coefficient of rxy = -0,549, p = 0,000 (p <0.01). Similarly, there is also a very significant negative relationship between resilience and job insecurity among contract employees, with a correlation coefficient of rxy = -0,476, p = 0,000 (p <0.01). Self�efficacy and resilience contribute 36% to job insecurity, while the remaining 64% are influenced by other factors outside the scope of this study
