Relating Voluntary Turnover with Job Characteristics, Satisfaction and Work Exhaustion - An Initial Study with Brazilian Developers

High rates of turnover among software developers remain, involving additional costs of hiring and training. Voluntary turnover may be due to workplace issues or personal career decisions, but it might as well relate to Job Characteristics, or even Job Satisfaction and Work Exhaustion. This paper reports on an initial study which quantitatively measured those constructs among 78 software developers working in Brazil who left their jobs voluntarily. For this, we adapted well-known survey instruments, namely the JDS from Hackman and Oldham's Job Characteristics Model, and Maslach et al.'s Burnout Measurement. In average, developers demonstrated low to moderate autonomy (3.75, on a 1-7 scale) and satisfaction (4.08), in addition to moderate exhaustion (4.2) before leaving their jobs, while experiencing high task significance (5.15). Also, testers reported significantly lower job satisfaction than programmers. These results allow us to raise interesting hypotheses to be addressed by future studies.Comment: 4 pages, no figures, 3 tables. Final version for ICSE CHASE 201

Gerenciamento de energia em ambientes corporativos.

Gerenciamento de energia é uma atividade fundamental a ser implementada em todos os sistemas computacionais na busca pela sustentabilidade na área de TI (TI Verde). Considerando- se o desempenho e o orçamento para o período como restrições a esse gerenciamento é possível alcançar eficiência energética. Neste estudo, é apresentada uma metodologia de gerenciamento de energia,na qual por meio da adaptação dinâmica atrelada à troca de estados de energia dos componentes, proporciona-se um menor consumo de energia,combinando as necessidades dos usuários e as restrições de orçamento.Energy management is a key activity to be implemented in all computer systems in the search for sustainability in IT (green IT). Considering the performance and the power budget for the period as constraints to this management, is possible to achieve energy efficiency. In this study, it is presented a methodology for power management, in which by means of dynamic adaptation tied to the exchange of energy States of components, provides a lower power consumption, combining the needs of users and budget constraints.Cape
