The MNC as a Knowledge Structure The Roles of Knowledge Sources and Organizational Instruments in MNC Knowledge Management

Recent research on the differentiated MNC has concerned knowledge flows between MNC units. While linking up with this literature, we extend in two directions. First, we argue that conceptualizing the MNC as a knowledge structure furthers the understanding of intra-MNC knowledge flows. Thus, we see MNC knowledge elements as being structured along such dimensions as their type and degree of complementarity to other knowledge elements, and their sources, for example, whether they are mainly developed from external or internal knowledge sources. These dimensions matter in terms of knowledge flows, because they influence the costs and benefits of knowledge transfer and, hence, the actual level of knowledge transferred. Second, based on this conceptualization, we argue that MNC management can influence the development, characteristics and transfer of knowledge through choices regarding organizational instruments (control, motivation and context). We test six hypotheses derived from these arguments against a unique dataset on subsidiary knowledge development. The dataset includes information on organizational instruments, sources of subsidiary knowledge, and the extent of knowledge transfer to other MNC units. It covers more than 2,000 subsidiaries located in seven different European countries.Knowledge structure, complementarity, knowledge transfer, the MNC

Happiness in Europe: Cross-Country Differences in the Determinants of Subjective Well-Being

The purpose in the present paper is to use individual panel data in the European Community Household Panel to analyse the impact on self-reported satisfaction from a number of economic and demographic variables. The paper contributes to the ongoing discussion of the relationship between life satisfaction and income. The panel property of the data makes it possible to study also the impact on satisfaction from income changes as well as the impact from acceleration in income and changes in labour market status on changes in satisfaction. A number of demographic variables and individual attitude indicators are also entered into the analysis of both the level of satisfaction and the change in satisfaction from one wave of the survey to the next. We find a strong impact from the level of income in all countries, an impact from change and acceleration in income for a smaller number of countries, a strong impact from most changes in labour market status and finally important effects from a number of demographic variables.satisfaction, income, labour market status, health

McStas and Mantid integration

McStas and Mantid are two well established software frameworks within the neutron scattering community. McStas has been primarily used for simulating the neutron transport of instruments, while Mantid has been primarily used for data reduction. We report here the status of our work done on the interoperability between the instrument simulation software McStas and the data reduction software Mantid. This provides a demonstration of how to successfully link together two software that otherwise have been developed independently, and in particular here show how this has been achieved for an instrument simulation software and a data reduction software. This paper will also provide examples of some of the expected future enhanced analysis that can be achieved from combining accurate instrument and sample simulations with software for correcting raw data. In the case of this work for raw data collected at large scale neutron facilities.Comment: 17 pages, 12 figures, POSTPRINT with proofs of article submitted to Journal of Neutron Researc

On the mass aspect function and positive energy theorems for asymptotically hyperbolic manifolds

We prove positivity of energy for a class of asymptotically locally hyperbolic manifolds in dimensions $4\le n \le 7$. The result is established by first proving deformation-of-mass-aspect theorems in dimensions $n\ge 4$. Our positivity results extend to the case $n = 3$ when more stringent conditions are imposed.Comment: trivial typos correcte

What Are Polymorphically-Typed Ambients?

Abstract: The Ambient Calculus was developed by Cardelli and Gordon as a formal framework to study issues of mobility and migrant code. We consider an Ambient Calculus where ambients transport and exchange programs rather that just inert data. We propose different senses in which such a calculus can be said to be polymorphically typed, and design accordingly a polymorphic type system for it. Our type system assigns types to embedded programs and what we call behaviors to processes; a denotational semantics of behaviors is then proposed, here called trace semantics, underlying much of the remaining analysis. We state and prove a Subject Reduction property for our polymorphically typed calculus. Based on techniques borrowed from finite automata theory, type-checking of fully type-annotated processes is shown to be decidable; the time complexity of our decision procedure is exponential (this is a worst-case in theory, arguably not encountered in practice). Our polymorphically-typed calculus is a conservative extension of the typed Ambient Calculus originally proposed by Cardelli and Gordon

Ultracold Chemistry and its Reaction Kinetics

We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key role in driving an ultracold reaction towards a dynamical equilibrium. In case of multiple concurrent reactions Hamiltonian chaos dominates the phase space dynamics in the mean field approximation.Comment: 15 pages, 5 figure
