The Curvilinear Relationship between Age and Emotional Aperture : The Moderating Role of Agreeableness

The capability to correctly recognize collective emotion expressions (i.e., emotional aperture) is crucial for effective social and work-related interactions. Yet, little remains known about the antecedents of this ability. The present study therefore aims to shed new light onto key aspects that may promote or diminish an individual’s emotional aperture. We examine the role of age for this ability in an online sample of 181 participants (with an age range of 18 to 72 years, located in Germany), and we investigate agreeableness as a key contingency factor. Among individuals with lower agreeableness, on the one hand, our results indicate a curvilinear relationship between age and emotional aperture, such that emotional aperture remains at a relatively high level until these individuals’ middle adulthood (with a slight increase until their late 30s) and declines afterwards. Individuals with higher agreeableness, on the other hand, exhibit relatively high emotional aperture irrespective of their age. Together, these findings offer new insights for the emerging literature on emotional aperture, illustrating that specific demographic and personality characteristics may jointly shape such collective emotion recognition

CP-violation parameters from decay rates of B±→DK±B^\pm \to D K^\pm, D→D\to multibody final states

We describe a method for measuring CP-violation parameters from which the Cabibbo-Kobayashi-Maskawa angle $\gamma$ may be extracted. The method makes use of the total decay rates in $B^\pm \to DK^\pm$ decays, where the neutral $D$ meson decays to multibody final states. We analyze the error of the method using experimental CP-violation analysis variables that enable straightforward sensitivity comparison with other methods for extracting $\gamma$, and discuss the use of $B$-factory and charm-factory data to obtain the relevant charm decay information needed for this measurement. Measurement sensitivities are estimated for the currently available $B$-factory data sample, and $D$ decay modes for which use of this method can make a significant contribution toward reducing the total error on $\gamma$ are identified.Comment: 9 pages, 2 figures, submitted to Phys.

Vertical foreign direct investment, welfare, and employment

This paper shows that vertical foreign direct investemt will reduce prices but the aggregate welfare effect is unambiguaously positive only under free market entry. Using a standard model of imperfect competition, we develop this result by considering two different cases. In the first case, the total number of firms is ficed, and we show that national and multinational firms may coexist. In the second case, we allow for market entry, and we focus on situations in which either only national or only multinational firms are active. Furthermore, we discuss impact effects on labor demand. We show that a decline in foreign wages increases domestic employment.

CP Violating Asymmetry in Stop Decay into Bottom and Chargino

In the MSSM with complex parameters, loop corrections to the decay of a stop into a bottom quark and a chargino can lead to a CP violating decay rate asymmetry. We calculate this asymmetry at full one-loop level and perform a detailed numerical study, analyzing the dependence on the parameters and complex phases involved. In addition, we take the Yukawa couplings of the top and bottom quark running. We account for the constraints on the parameters coming from several experimental limits. Asymmetries of several percent are obtained. We also comment on the feasibility of measuring this asymmetry at the LHC.Comment: Contributed talk given by Sebastian Frank in June 2009 at SUSY09 - 17th International Conference on Supersymmetry and the Unification of Fundamental Interactions, Northeastern University, Boston, USA.
