Readiness for Change in the Relationship between Abusive Supervision and Innovative Self-efficiency of Employees of Shiraz University of Medical Sciences

Background: The negative behaviors and abuse of supervisory tasks have negative consequences for employees and organizations. One of these consequences is reduction of readiness for change and innovation capability in organizations. Therefore, the aim of this study was to investigate the role of readiness for change in the relationship between abusive supervision and innovative self-efficiency of employees of Shiraz University of Medical Sciences in 2015. Methods: This is a cross-sectional study using path analysis. In this study, 216 employees of Shiraz University of Medical Sciences were selected using random sampling. The research questionnaires included abusive supervision, readiness for change, and innovative self-efficiency of employees that their reliability and validity were approved. Data were analyzed using SPSS 22, Lisrel 8.50, Pearson’s correlation coefficient, and simple and multiple regressions. Results: The results showed that abusive supervision had a significant negative effect on different aspects of readiness for change (P<0.0001). Emotional readiness for change had a significant positive effect on employees’ innovative self-efficiency (P<0.0001) and played a mediation role in the relationship between abusive supervision and employees’ innovative self-efficiency. Conclusion: Since innovation leads to changes in the organization; therefore, employees should be prepared for these changes in advance. This preparation can be increased or decreased by the supervision methods used by the managers and their supervisory behaviors

Aggregated effect of demand response on performance of future grid scenarios

Session 32 - Future power system infrastructure: no. 459750Conference Theme: Towards Future Power Systems and Emerging TechnologiesThe existing future grid (FG) feasibility studies have mostly considered simple balancing, but largely neglected network related issues and the effect of demand response (DR) for modelling nett future demand. This paper studies the effect of DR on performance of the Australian National Electricity Market in 2020 with the increased penetration of renewable energy sources (RESs). The demand model integrates the aggregated effect of DR in a simplified representation of the effect of market/dispatch processes aiming at minimising the overall cost of supplying electrical energy. The conventional demand model in the optimisation formulation is augmented by including the aggregated effect of numerous price anticipating users equipped with rooftop photovoltaic (PV)-storage systems. Simulation results show that increasing penetration of DR improves loadability and damping of the system with the increased penetration of RESs.postprin

The Relationship between Antecedents and Processes of Unlearning and Organizational Innovation among Hamedan Teaching Hospitals

Introduction: Hospitals should provide necessary conditions for the renewal of knowledge, skill and attitude through unlearning. Thus, the present study aimed to determine the relationship between antecedents and processes of unlearning and organizational innovation among the teaching hospitals of Hamedan. Methods: This is a descriptive correlational study. The statistical population of the study included 1352 health personnel in four teaching hospitals of Hamedan. To select the administrative personnel, we used the total population; also, for physicians, and for the health personnel we used purposeful voluntary sampling and stratified random sampling, respectively. Based on the methods, 431 were selected as the subjects. Research instruments were unlearning researcher-made questionnaire and innovation scale. Data were analyzed through multivariate regression analysis and structural equation model using SPSS19 and LISREL 8.54 software. Results: The results indicated that organizational support and training, frequency of changes, and predictability of changes were the positive and significant predictors of the product, process and administrative dimensions. The group crisis was the negative and significant predictor of the product and administrative dimensions. Organizational memory was the positive and significant predictor of the administrative dimension. Individual processes, group processes, and organizational processes were the positive and significant predictors of organizational innovation. Conclusion: Based on the effective role of organizational support and training, organizational memory and frequency of changes and predictability of changes on innovation in teaching hospitals, it is suggested that the administrators and authorities of the hospitals should accept new opinions of their personnel

Modelling and Stability Assessment of Future Grid Scenarios

With the increased penetration of intermittent renewable energy sources (RESs) in future grids (FGs), balancing between supply and demand will become more dependent on demand response (DR) and energy storage. So far, FG feasibility studies, especially those claiming a long-term view, typically do not model the electrical network and/or the effect of DR. Thus, in this thesis, we first present a simulation platform for performance and stability assessment of FG scenarios. The platform considers market simulation, load flow calculation and stability assessment together. Using the platform, we illustrate how displacing conventional generators with RESs, especially inverter-based and intermittent RESs, could have significant impacts on performance and stability of FGs, confirming the importance of stability assessment for FG feasibility studies. Second, to carry out accurate stability analysis of FG scenarios, we need a representation of the aggregate demand including the effect of emerging demand-side technologies (distributed generation (DG), DR and storage). In this research, we propose generic demand models including the aggregated impact of price-responsive users equipped with emerging demand-side technologies (prosumers). The proposed models capture essential behaviour of the prosumers without giving lots of detail which is costly in repeated use for applications such as scenario comparisons. So, such models demand some simplifications, just as conventional generic load modelling did. The proposed frameworks are based on the unit commitment (UC) problem aiming to minimise the system cost. The conventional demand model in the associated optimisation formulations are augmented by including the aggregated influences of prosumers equipped with rooftop photovoltaics (PV)-battery systems. It is noted that as the frameworks are generic, they are capable of easy integration of other demand-side technologies as well. The developed frameworks are intended specifically for modelling net demand by including the impact of prosumers in FG scenario studies. Nevertheless, they do not assume any particular market structure. As such, they are not suitable for modelling of existing electricity markets, but rather their aim are to capture the behaviour of future electricity markets provided a suitable market structure is adopted. Finally, the impact of prosumers on performance and voltage stability of the Australian National Electricity Market (NEM) is studied with the increased penetration of RESs in the grid. We have considered different penetrations of RESs, and assessed the influence of different penetrations of prosumers on the balancing, loadability and voltage stability of the NEM
