Contemporary trends in Brazilian human resource management studies over the last decade (2001–2010)

In seeking to detail what is new in the lesser-known field of Brazilian Human Resource Management (HRM) research, this study analyzes 136 recent Brazilian HRM articles over the last decade from 2001 until 2010. Findings reveal that contemporary Brazilian HRM research contains: a wide range of HRM topics; the isomorphic use of some Western HRM themes; and case-based, descriptive methodologies using non-probability sampling. While the number of recently published Brazilian HRM studies has increased, such research seems ripe for further empirical and theoretical development. Our contributions to knowledge lie in: surfacing and classifying recent Brazilian HRM research trends and identifying potentially fruitful areas for future research. Implications for practitioners include the need to attract and retain expert staff, to use more localized pay and reward systems, and to assess the usefulness of HR interventions in the public sector

Search for supersymmetry in pp collisions at root s=8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets

Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are identified as b jets. The data sample corresponds to an integrated luminosity of 19.3 fb-1recorded by the CMS experiment at the LHC in 2012. The search is motivated by supersymmetric models that involve strong-production processes and cascade decays of new particles. The resulting final states contain multiple jets as well as missing transverse momentum from weakly interacting particles. The event yields, observed across several kinematic regions, are consistent with the expectations from standard model processes. The results are interpreted in the context of simplified supersymmetric scenarios with pair production of gluinos, where each gluino decays to a top quark-antiquark pair and the lightest neutralino. For the case of decays via virtual top squarks, gluinos with a mass smaller than 1.26 TeV are excluded for low neutralino masses. © 2014 The Authors
