What Do We Assess when We Assess a Big 5 Trait? A Content Analysis of the Affective, Behavioral, and Cognitive Processes Represented in Big 5 Personality Inventories

Abstract: What are personality traits? Are all “broad” traits equally broad in the constructs they encompass and in the pervasiveness of their effects? Or are some traits more or less affective, behavioral, or cognitive in nature? The present study examined these issues as they applied to the Big 5 traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness. Expert and novice raters judged the extent to which items from four popular Big 5 inventories contain behavioral, cognitive, or affective components. Traits and inventories were then compared in terms of their relative assessment of these components. Results indicate convergence among inventories but remarkable differences between traits. These findings have implications for the conceptualization and assessment of traits and suggest directions for future research.

The positive impact and development of hopeful leaders

Abstract: Although hope is commonly used in terms of wishful thinking, as a positive psychological concept consisting of the dimensions of both willpower (agency) and waypower (pathways), it has been found to be positively related to academic, athletic and health outcomes The impact of hopeful leaders, however, has not been empirically analyzed This exploratory study (N = 59) found that high‐ as compared to low‐hope leaders had more profitable work units and had better satisfaction and retention rates among their subordinates The implications of these preliminary findings of the positive impact that hopeful leaders may have in the workplace are discussed

The Role of Relational Knowledge Stores in Interfirm Partnering

Abstract: Drawing on the notions of relational capabilities and absorptive capacity, the authors examine the effects of interactional, functional, and environmental knowledge stores on relationship quality and relationship portfolio effectiveness. The results suggest that the knowledge stores affect the outcome variables differently and that the effects vary by levels of industry turbulence.

Infrared dielectric anisotropy and phonon modes of sapphire

Abstract: Spectroscopic ellipsometry in the infrared spectral range is used for comprehensive analysis of the anisotropic dielectric response of sapphire. We determine the ordinary and extraordinary infrared complex dielectric functions as well as all infrared-active phonon modes of single crystal $\ensuremath{\alpha}\ensuremath{-}{\mathrm{Al}}_{2}{\mathrm{O}}_{3}$ for wavelengths from 3 to 30 \ensuremath{\mu}m. Data were acquired from high-symmetry orientations of a-plane and c-plane surfaces cut from bulk crystals. A simple classification scheme is developed, which allows identification of the total reflection bands for p- and s-polarized light in anisotropic materials with multiple phonon branches. We employ a factorized form of the dielectric function for superior best-fit calculation of the infrared ellipsometry spectra adjusting frequencies and damping parameters of the transverse and longitudinal phonon modes with ${A}_{2u}$ and ${E}_{u}$ symmetry separately. A generalized Lowndes condition for the damping parameters is derived and found satisfied for the ${A}_{2u}$ and ${E}_{u}$ branches. Excellent agreement with phonon mode literature values is obtained, and improper use of selection rules reported previously for calculation of the sapphire dielectric functions is revised [Harman, Ninomiya, and Adachi, J. Appl. Phys. 76, 8032 (1994)]. The dielectric function model will become useful for infrared ellipsometry investigation of multiple-layer structures grown on $\ensuremath{\alpha}\ensuremath{-}{\mathrm{Al}}_{2}{\mathrm{O}}_{3}$ substrates such as group-III nitride heterostructures.

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s=8 Tev

Abstract: A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at sqrt(s)=8 TeV using a data sample corresponding to an integrated luminosity of 19.5 inverse femtobarns collected with the CMS detector at the LHC. The data sample is divided into three jet multiplicity categories (3-5, 6-7, and 8 or more jets), and studied further in bins of two variables: the scalar sum of jet transverse momenta and the missing transverse momentum. The observed numbers of events in various categories are consistent with backgrounds expected from standard model processes. Exclusion limits are presented for several simplified supersymmetric models of squark or gluino pair production.
