Participation of Married Women in the Labour Market and the 'Added Worker Effect' in Europe

In this paper, we estimate labour participation equations for married women for eleven European countries, using data from the European Community Household Panel corresponding to the years 1994, 1995 and 1996. The main objective of our study is to test whether the 'added worker effect' holds. From our results it can be concluded that the labour market participation of the married woman basically depends on her personal and family characteristics, her non-wage income and her potential earnings. In only a few countries does the participation of married women seem to be related to the work status of the husband. However, the consistently significant and negative effect of the woman's non-wage income (basically the husband's wage) prevents the 'added worker effect' from being completely rejected as a hypothesis. It seems, therefore, that female labour market participation continues to have a 'secondary' role in the family sphere in some European countries.Female participation ; added worker effect

Innovation and jobs: evidence from manufacturing firms

This paper is aimed at structurally assessing the employment effects of the innovative activities of firms. We estimate firm level displacement and compensation effects in a model in which the stock of knowledge capital raises firm relative efficiency through process innovations and firm demand through product innovations. Displacement is estimated from the elasticity of employment with respect to innovation in the (conditional or Hicksian) demand for labour. Compensation effects are estimated from a firm-specific demand relationship. We also assess the enlargement and weakening of these effects due to firm agents’ behaviour aimed at appropriating innovation rents. We find that the potential employment compensation effect of process innovations surpasses the displacement effect, both in the short and long run (when competitors react), and that product innovation doubles the expanding impact by unit of expenditure, but also that agents’ behaviour can seriously reduce these effects. The actual elasticity of employment to knowledge capital is estimated, however, not far from unity, while “passive” productivity growth is suggested to have null or negative employment effects

Unfolding-based Partial Order Reduction

Partial order reduction (POR) and net unfoldings are two alternative methods to tackle state-space explosion caused by concurrency. In this paper, we propose the combination of both approaches in an effort to combine their strengths. We first define, for an abstract execution model, unfolding semantics parameterized over an arbitrary independence relation. Based on it, our main contribution is a novel stateless POR algorithm that explores at most one execution per Mazurkiewicz trace, and in general, can explore exponentially fewer, thus achieving a form of super-optimality. Furthermore, our unfolding-based POR copes with non-terminating executions and incorporates state-caching. Over benchmarks with busy-waits, among others, our experiments show a dramatic reduction in the number of executions when compared to a state-of-the-art DPOR.Comment: Long version of a paper with the same title appeared on the proceedings of CONCUR 201

Linear Assignment Maps for Correlated System-Environment States

An assignment map is a mathematical operator that describes initial system-environment states for open quantum systems. We reexamine the notion of assignments, introduced by Pechukas, and show the conditions assignments can account for correlations between the system and the environment, concluding that assignment maps can be made linear at the expense of positivity or consistency is more reasonable. We study the role of other conditions, such as consistency and positivity of the map, and show the effects of relaxing these. Finally, we establish a connection between the violation of positivity of linear assignments and the no-broadcasting theorem.Comment: 6 pages, 1 tabl

El pragmatismo trascendental y dialógico de Jürgen Habermas

La discusión propuesta se divide en dos mitades. En la primera parte, defendemos una interpretación de la teoría de la pragmática universal en términos de pragmatismo trascendental, muy en la línea de las propuestas firmadas por Karl-Otto Apel. En la segunda parte, nos solidarizamos con la idea de Pere Fabra según la cual el uso comunicativo del lenguaje difícilmente puede sentar las bases de todos los fines ilocutivos en que consisten los actos de habla

Acerca de la geomedicina: una aproximación desde la filosofía

El presente ensayo tiene el objetivo de acercarnos al estudio de la geomedicina. Después de una breve introducción al estado de la cuestión, nos preguntamos por el status científico de la geomedicina. Al efecto, basándonos en un criterio de validez cientíThis paper aims to approach the study of geomedicine. After a brief introduction to the stage of the question, we wonder about the scientific status of geomedicine. To this end, on the basis of a scientific validity criterium that invokes the clinical us
