light traffic behavior under the power of two load balancing strategy the case of heterogeneous servers
Performance Evaluation, 2017Co-Authors: Ane Izagirre, Armand M MakowskiAbstract:Abstract We consider a multi-server queueing system under the power-of-two policy with Poisson Job arrivals, heterogeneous servers and a general Job Requirement distribution; each server operates under the first-come first-serve policy and there are no buffer constraints. We analyze the performance of this system in light traffic by evaluating the first two light traffic derivatives of the average Job response time. These expressions point to several interesting structural features associated with server heterogeneity in light traffic: For unequal capacities, the average Job response time is seen to decrease for small values of the arrival rate, and the more diverse the server capacities, the greater the gain in performance. These theoretical findings are assessed through limited simulations.

individual innovative behavior interplay of reputation Job Requirement and expected positive performance outcomes
Social Science Research Network, 2017Co-Authors: Tehmina Latif, Faisal Qadeer, Saira FarooqiAbstract:This study attempts to find the answer to a broader research question, why do employees engage in innovative behavior at their workplace? We empirically investigate the impact of expected positive performance outcomes (EPPO) on individual innovative behavior, where antecedents namely innovativeness shapes these expectations as a Job Requirement (IJR) and reputation as an innovative person (RIP). The multi-source data (34 managers and 200 employees) from randomly selected work units at the head office of a large bank was collected through structured questionnaires. Various statistical techniques including structural equation modeling (SEM) was carried out to test the theoretically grounded hypotheses. The findings indicate a mediating effect of EPPO in the relationship between: a) IJR and individual innovative behavior and between, b) RIP and individual innovative behavior. The implication for theory and practice are discussed towards the end of the paper.

The Impact of Work Life Balance and Job Satisfaction on Organisational Commitment among Female Employees: A Case of Harare Central Registry.
2016Co-Authors: Pachena, Brenda NAbstract:This study uncovers the family and work dimension, digging deeper into the impact that work-life balance and Job satisfaction has on organisational commitment. It explores the relationship that these three variables have on each other. Factors involved include emotional attachment to the organisation, sense of belonging and Job Requirement satisfaction. Work life is predicted to foster satisfaction and therefore lead to commitment in the long run. Work life was measured using nine (9) statements, Job satisfaction using five statements and organisational commitment using eight (8) statements. A total of fifty (50) questionnaires were distributed out of which thirty-five (35) were returned after filling. No probabilistic method was used to choose the sample. Summary statistics were calculated and explanations were based on these and other qualitative reasons. The need to investigate and deepen the understanding of the implication of lacking balance between work and life can be connected to many factors which are stated in the body of the research. The findings of the research indicated that work life balance, Job satisfaction and organisational commitment have a significant relationship. When controlling for demographic and professional experience, the results also indicated that age, marital status and culture were significant predicators for work life balance. The results also showed that female employees that are married with children have lower Job satisfaction. Mostly, single employees show a degree of satisfaction whereas their married counterparts lacked it. This may be attributed by the ever increasing responsibilities brought about by marriage. Pay and sense of belonging were found to be predicators for Job satisfaction. The results also indicated that the level of commitment was lower for married middle aged employees due to the responsibilities that are mostly expected of them at home. The findings of this study provide valuable insight for managers and policy makers who are interested in factors that contribute to work- life balance, overall Job satisfaction and organisational commitment among females employees,Lupane State Universit
