It represents advancement towards discriminant validity of such linkages that develop between individuals and the organizations they work for. A survey of 307 participants was conducted in an Information Technology company in Brazil. It was found that affective commitment has a strong and positive relationship with perceptions of HRM practices, while entrenchment is also related, but in a very weak fashion. Training and development practices showed better fit with the expected results of such practices in the organization studied, strongly affecting commitment, but not enhancing entrenchment. Even if not generalizable, these results strengthen the research stream that defends that commitment and entrenchment are separate constructs.

Para tanto, utilizou-se a técnica de análise envoltória dos dados em dois estágios. Os resultados da pesquisa permitiram concluir que os benefícios pagos pela previdência social impactaram, positivamente, a eficiência municipal na promoção do desenvolvimento socioeconômico.

However, Eling (2008) compared the Sharpe ratio with some of these performance measures, and found virtually identical rank ordering using mutual fund data. This paper compares 13 performance measures with the traditional Sharpe Ratio using a sample of US Fixed-Income, Equity and Asset Allocation Mutual Funds. Results show that performance measures based on absolute reward-risk ratios have similar rankings, when the numerator (mean excess return) is the same. However, when we move to other types of performances measures, results may be significantly different. This is the case of the Manipulation-Proof Performance Measure (MPPM), Upside Potential Ratio, and Appraisal Ratio. Results are especially different for the MPPM. Robustness checks show that some of the performance measures are very sensitive to parameters' changes. Therefore, the choice of the performance measure is actually important for mutual fund ranking and selection. As a consequence, we argue that the use of several performance measures and rankings have a positive impact on the mutual fund's industry, reducing concentration.

A way to achieve it is by establishing a government interoperability framework (GIF). However, this is a difficult task to be carried out due not only to technological issues but also to other aspects. This research is expected to contribute to the identification of the barriers to the adoption of interoperability standards for electronic government. The article presents the preliminary findings from a case study of the Brazilian Government framework (e-PING), based on the analyses of documents and face-to-face interviews. It points out some aspects that may influence the establishment of these standards, becoming barriers to their adoption. Tipo: Artigo de Periódico 2012-01-01T00:00:00Z
