The Role of Family Ties in Agency Contracts.

Drawing on data based on the entire population of Spanish newspapers over 27 years (1966-93), this study shows that firm performance and business risk are much stronger predictors of chief executive tenure when a firm's owners and its executive have family ties and that the organizational consequences of CEO dismissal are more favorable when the replaced CEO is a member of the family owning the firm. The study also demonstrates that executives operating under weakly relational (less ambiguous) contracts are held more accountable for firm performance and business risk outcomes, even under nonfamily contracting.

Derechos humanos y fenómeno migratorio: entre el abismo del discurso y los hechos

EN LA ACTUALIDAD EL FENÓMENO MIGRATORIO SE HA CONSTITUIDO EN EL mayor desafío para las sociedades desarrolladas, especialmente de Europa y Estados Unidos, ya que pone a prueba los valores de libertad, igualdad y fraternidad que fundamentan el discurso emancipador de los derechos humanos que dichas regiones promueven desde hace más de 200 años. Paradójicamente, mientras se sigue proclamando la universalidad de tales derechos y la igualdad de las personas, la práctica de lospaíses desarrollados se caracteriza por la implementación de políticas migratorias restrictivas y de criminalización que condenan a la ilegalidad a millones de personas. En este sentido, la intención de este artículo es aportar una prueba más de la esquizofrenia que subyace en la actitud de los países receptores en torno a la migración, pues por un lado proclaman una visión de los derechos humanos de todas las personas sin discriminación alguna, pero por otro lado, tal visión se fractura cuando un migrante llega a sus fronteras, y sus derechos, que deberían ser reconocidos “universalmente”, se esfuman ante la exigencia de un documento quefinalmente determina si tiene o no derechos

Nonequilibrium dynamics of a stochastic model of anomalous heat transport: numerical analysis

We study heat transport in a chain of harmonic oscillators with random elastic collisions between nearest-neighbours. The equations of motion of the covariance matrix are numerically solved for free and fixed boundary conditions. In the thermodynamic limit, the shape of the temperature profile and the value of the stationary heat flux depend on the choice of boundary conditions. For free boundary conditions, they also depend on the coupling strength with the heat baths. Moreover, we find a strong violation of local equilibrium at the chain edges that determine two boundary layers of size $\sqrt{N}$ (where $N$ is the chain length), that are characterized by a different scaling behaviour from the bulk. Finally, we investigate the relaxation towards the stationary state, finding two long time scales: the first corresponds to the relaxation of the hydrodynamic modes; the second is a manifestation of the finiteness of the system.Comment: Submitted to Journal of Physics A, Mathematical and Theoretica

Density dynamics from current auto-correlations at finite time- and length-scales

We consider the increase of the spatial variance of some inhomogeneous, non-equilibrium density (particles, energy, etc.) in a periodic quantum system of condensed matter-type. This is done for a certain class of initial quantum states which is supported by static linear response and typicality arguments. We directly relate the broadening to some current auto-correlation function at finite times. Our result is not limited to diffusive behavior, however, in that case it yields a generalized Einstein relation. These findings facilitate the approximation of diffusion constants/conductivities on the basis of current auto-correlation functions at finite times for finite systems. Pursuing this, we quantitatively confirm the magnetization diffusion constant in a spin chain which was recently found from non-equilibrium bath scenarios.Comment: 4 pages, 1 figure, accepted for publication in Europhys.

The importance of various work aspects and their organiza tional consequences using Hofstede's cultural dimensions

This study examines the importance employees place on various work aspects according to their nation's relative positioning along Hofstede's four cultural dimension: power distance, individualism, uncertainty avoidance, and masculinity/feminity. Based on a cross-national sample of over 5,000 employees representing 20 countries, the results uncover differential patterns of responses by cultural groupings. The data also suggest that importance and satisfaction interactively affect several organizational consequences critería: job satisfaction, company satisfaction, intent to leave the firm, and organizational cornmitment

The linkages between business strategies and compensation policies using miles and snow's framework

This study links a multidimensional measure of compensatíon strategy to Miles and Snow's (1978) business strategies, and examines their interactive impact on firm performance. The results reported here indicate that a more mechanistic compensation strategy makes a greater contribution to firm performance among defenders, while a more organic compensation strategy makes a greater contribution to firm performance among prospector

Management education in Ibero-America : an exploratory analysis and perspective

Considering the importance of management education for society and the pedagogical inadequacies that pose a threat to academic institutions, this article develops an exploratory approach for evaluating and monitoring the quality of management education within an Ibero American context. Latin American countries and Spain tend to think of themselves as an Ibero American region, so the overview of key issues in management education in this article is pertinent to the entire region. The data is important to policymakers who wish to enhance the quality of higher education, since well trained managers contribute to successful business strategies and superior organizational performance. Unfortunately, there is almost no empirical work available on the performance and effectiveness of higher education in Ibero American countries. Our study helps bridge that gap by providing useful data for evaluating and reflecting upon some of the variables associated with management education in a sample of Ibero American universities.Publicad
