Employee Empowerment and Turnover Intention in the U.S. Federal Bureaucracy

Abstract: Reducing employee turnover in the U.S. federal government has been an ongoing goal of policymakers in Washington, D.C. A large literature emerging during the last three decades has identified a range of antecedents of turnover intention and actual turnover, including individual characteristics, employee attitudes, organizational conditions, and managerial practices. Little research has been done, however, on the impact of employee empowerment as a multifaceted managerial approach on turnover options in the public sector. This study proposes a theoretical model of the direct and indirect effects of employee empowerment on turnover intention in the U.S. federal bureaucracy. The model is tested using structural equation modeling (SEM) and data from the U.S. Federal Employee Viewpoint Survey (FEVS). The empirical results support the hypothesized model. Employee empowerment has negative direct and indirect effects on turnover intention. In addition, the negative effect is greater on the likelihood of intention...

The Specificity of Observational Studies in Physical Activity and Sports Sciences: Moving Forward in Mixed Methods Research and Proposals for Achieving Quantitative and Qualitative Symmetry.

Abstract: Mixed methods studies are been increasingly applied to a diversity of fields. In this paper, we discuss the growing use—and enormous potential—of mixed methods research in the field of sport and physical activity. A second aim is to contribute to strengthening the characteristics of mixed methods research by showing how systematic observation offers rigor within a flexible framework that can be applied to a wide range of situations. Observational methodology is characterized by high scientific rigor and flexibility throughout its different stages and allows the objective study of spontaneous behavior in natural settings, with no external influence. Mixed methods researchers need to take bold yet thoughtful decisions regarding both substantive and procedural issues. We present three fundamental and complementary ideas to guide researchers in this respect: we show why studies of sport and physical activity that use a mixed methods research approach should be included in the field of mixed methods research, we highlight the numerous possibilities offered by observational methodology in this field through the transformation of descriptive data into quantifiable code matrices, and we discuss possible solutions for achieving true integration of qualitative and quantitative findings.

Search for strong production of supersymmetric particles in final states with missing transverse momentum and at least three b-jets at √s = 8 TeV proton-proton collisions with the ATLAS detector

Abstract: This paper reports the results of a search for strong production of supersymmetric particles in 20.1 fb(-1) of proton-proton collisions at a centre-of-mass energy of 8 TeV using the ATLAS detector at the LHC. The search is performed separately in events with either zero or at least one high-p (T) lepton (electron or muon), large missing transverse momentum, high jet multiplicity and at least three jets identified as originated from the fragmentation of a b-quark. No excess is observed with respect to the Standard Model predictions. The results are interpreted in the context of several supersymmetric models involving gluinos and scalar top and bottom quarks, as well as a mSUGRA/CMSSM model. Gluino masses up to 1340 GeV are excluded, depending on the model, significantly extending the previous ATLAS limits.
