Do national levels of individualism and internal locus of control relate to well- being : an ecological level international study

Abstract: There has been increasing interest in cross-national research that attempts to understand differences and similarities among employees from different cultures and nations. One of the basic issues of concern to organizational researchers is the health and well-being of employees, and it has been viewed as both a response to the work environment and as an affect-related antecedent of other employee outcomes such as job performance or turnover. Employee control beliefs and perceptions have been linked to well-being and play an important role (Ganster and Fusilier, 1989; Spector, 1982). Although there is a tremendous amount of research at the individual level relating control and other variables to well-being, most has been done in the USA and a handful of western nations, and most has targeted the individual employee. Our study compared managers from 24 nations/territories at the ecological or sample mean level (Leung and Bond, 1989), as opposed to the individual participant level, in order to draw more definitive conclusions about nation differences.

Search for supersymmetry in hadronic final states using MT2 in pp collisions at √s = 7 TeV

Abstract: A search for supersymmetry or other new physics resulting in similar final states is presented using a data sample of 4.73 inverse femtobarns of pp collisions collected at sqrt(s)=7 TeV with the CMS detector at the LHC. Fully hadronic final states are selected based on the variable MT2, an extension of the transverse mass in events with two invisible particles. Two complementary studies are performed. The first targets the region of parameter space with medium to high squark and gluino masses, in which the signal can be separated from the standard model backgrounds by a tight requirement on MT2. The second is optimized to be sensitive to events with a light gluino and heavy squarks. In this case, the MT2 requirement is relaxed, but a higher jet multiplicity and at least one b-tagged jet are required. No significant excess of events over the standard model expectations is observed. Exclusion limits are derived for the parameter space of the constrained minimal supersymmetric extension of the standard model, as well as on a variety of simplified model spectra.
