The impact of cultural intelligence on communication effectiveness, job satisfaction and anxiety for Chinese host country managers working for foreign multinationals

Cultural intelligence (CQ) is an important construct attracting growing attention in academic literature and describing cross-cultural competencies. To date, researchers have only partially tested the relationship between CQ and its dependent variables, such as performance. In this study, the relationship between CQ and communication effectiveness and job satisfaction is measured in a sample of 225 Chinese managers working for foreign multinational enterprises in China. The results show that CQ plays an important role in reducing anxiety and influencing both communication effectiveness and job satisfaction positively. Another outcome is the unexpected influence of anxiety on job satisfaction but not on communication effectiveness. These findings contribute to the development of theory with regard to the CQ construct

What influences the actual use of competency management by the first-line manager?

Existing research shows that the first-line manager plays an important role in actually using HRM in general and competency management in particular. Existing theory and research in both domains point at a gap in understanding the mechanisms ‘how’ the actual enactment of the line takes place. In order to look into this gap, we present two models in which we adopt insights from competency management literature, HRM literature and social exchange theory. The first model treats the first-line manager’s exchange relationship with the HR function. The central hypothesis is that the quality of this exchange relationship mediates the inducements by the HR function at the one hand and the actual use of competency management at the other hand. In our second model, we treat the first-line manager’s exchange relationship with his senior manager. The central hypothesis here is that the quality of this exchange relationship mediates the inducements by the senior manager at the one hand and the actual use of competency management at the other hand. If these hypotheses are confirmed this will have important implications for practitioners pursuing actual use of competency management by the line

When affective well-being is empowered : the joint role of leader-member exchange and the employment relationship

HRM and the leader are often assumed to play a joint role in affecting employee reactions. In a multilevel, time-lagged study, we examined the joint role of the employment relationship and leader-member exchange. We tested whether this joint role is essential to when leader-member exchange leads to affective well-being via psychological empowerment. We build on HRM literature to expect that the relationship of leader-member exchange with psychological empowerment is stronger when the employment relationship is consistent with leader-member exchange quality. Results indicated that psychological empowerment mediates the relationship between leader-member exchange and affective well-being. This mediation is stronger for employees in a mutual investment employment relationship. The findings point at the importance of consistency of resources from the employment relationship and leader-member exchange. Nevertheless, the findings also suggest that resources from leader-member exchange compensate for employment relationships with low resources. Our findings contribute to scholars’ understanding of the joint role of HRM systems and leader behaviors

Hamiltonian simulation of the Schwinger model at finite temperature

Using Matrix Product Operators (MPO) the Schwinger model is simulated in thermal equilibrium. The variational manifold of gauge invariant MPO is constructed to represent Gibbs states. As a first application the chiral condensate in thermal equilibrium is computed and agreement with earlier studies is found. Furthermore, as a new application the Schwinger model is probed with a fractional charged static quark-antiquark pair separated infinitely far from each other. A critical temperature beyond which the string tension is exponentially suppressed is found, which is in qualitative agreement with analytical studies in the strong coupling limit. Finally, the CT symmetry breaking is investigated and our results strongly suggest that the symmetry is restored at any nonzero temperature.Comment: Updated manuscript matching its published version: more detailed continuum extrapolation of chiral condensate in section II

Tensor networks for gauge field theories

Over the last decade tensor network states (TNS) have emerged as a powerful tool for the study of quantum many body systems. The matrix product states (MPS) are one particular class of TNS and are used for the simulation of (1+1)-dimensional systems. In this proceeding we use MPS to determine the elementary excitations of the Schwinger model in the presence of an electric background field. We obtain an estimate for the value of the background field where the one-particle excitation with the largest energy becomes unstable and decays into two other elementary particles with smaller energy.Comment: Proceeding of talk presented at the 33rd International Symposium on Lattice Field Theory, 14-18 July 2015, Kobe, Japan; Proceeding of talk presented at The European Physical Society Conference on High Energy Physics, 22-29 July 2015, Vienna, Austria (PoS(EPS-HEP2015)375

Matrix product states for Hamiltonian lattice gauge theories

Over the last decade tensor network states (TNS) have emerged as a powerful tool for the study of quantum many body systems. The matrix product states (MPS) are one particular case of TNS and are used for the simulation of 1+1 dimensional systems. In [1] we considered the MPS formalism for the simulation of the Hamiltonian lattice gauge formulation of 1+1 dimensional one flavor quantum electrodynamics, also known as the massive Schwinger model. We deduced the ground state and lowest lying excitations. Furthermore, we performed a full quantum real-time simulation for a quench with a uniform background electric field. In this proceeding we continue our work on the Schwinger model. We demonstrate the advantage of working with gauge invariant MPS by comparing with MPS simulations on the full Hilbert space, that includes numerous non-physical gauge variant states. Furthermore, we compute the chiral condensate and recover the predicted UV-divergent behavior.Comment: presented at the 32nd International Symposium on Lattice Field Theory (Lattice 2014), 23 - 28 June 2014, New York, US
