In the current meta-analysis, we examine the relation between age and workplace deviance, and find a small but significant negative correlation (rho = -.092, k = 198). More importantly, we test two complementary mechanisms to help explain this relation. Specifically, based on the neo-socioanalytical model of personality change, we hypothesized that those Big Five personality domains that change with age and trait negative affect would mediate this relation. These hypotheses were supported, as the Big Five traits conscientiousness, agreeableness, and neuroticism, as well as trait negative affect simultaneously mediated the negative relation between age and workplace deviance. These findings highlight two important underlying mechanisms for this relation and suggest several opportunities for organizations to reduce the occurrence of workplace deviance. Further theoretical and practical implications as well as limitations and future research ideas are discussed.

This paper seeks to clarify the impact of time wasting on the weak performance, efficiency and effectiveness of their operations at Abuad cafeteria by applying queuing theory in a real life situation. We obtained the data from the major cafeteria in Abuad. derive the arrival rate, service rate, utilization rate, waiting time in queue. Based on the data Little's Theorem and M/M/1 queuing model was also considered. The arrival rate at at Abuad cafeteria during its busiest period of the day is 2.92 cus per minute (cpm) while the service rate is 2.95 cpm. The average number of customers in the cafeteria is 219 and the utilization period is 0.995. We conclude the paper by given the concluding remark and acknowledge.
