General mental ability as moderator of personality traits as predictors of early career success

In this paper, we examine the effects of general mental ability (GMA) and the personality traits defined in the big five model on extrinsic and intrinsic indicators of career success, in a sample of 130 graduates who were in the early stages of their careers. Results from hierarchical regression analyses indicated that GMA does not predict any of the success indicators. In contrast, the combination of GMA and three of the Big Five Personality traits, conscientiousness, neuroticism, and openness, is significantly associated with greater early career success and has incremental predictive validity.

Migraciones interregionales en España (1960-1989): cambios y barreras

En este trabajo se analizan los cambios en el patrón de las migraciones interiores españolas a lo largo del período 1960-1989. De forma preliminar y de acuerdo con las teorías explicativas de los flujos migratorios, se contrasta econométricamente la consistencia de estos cambios con la existencia de sistemas regionales económicamente desequilibrados versus sistemas regionales con diferencias compensadoras. Como resultado, se encuentra que a pesar de la reciente intensificación de las migraciones interiores y a diferencia de lo sucedido en otras etapas y bajo otras circunstancias, ahora no se debería confiar en que los movimientos migratorios puedan contribuir al acercamiento a la media nacional de las regiones con tasas de desempleo más elevadas. Esta vía podría haberse agotado en la medida en que el peso de las barreras procedentes de los mercados de trabajo y de los mercados inmobiliarios es creciente y, paradójicamente, ha generado flujos inte-rregionales equilibrados y no polarizados. Si, además, la posibilidad de que la emigración cumpla un papel dinamizador del ajuste económico se ve afectada por el componente de desempleo de los trabajadores que se desplazan, entonces las políticas públicas no deberían centrarse en la incentivación de los flujos de forma indiscriminada sino, más bien, en los aspectos microeconómicos referentes a la disponibilidad de información, la orientación y la capacitación de los potenciales trabajadores emigrantes.

La identidad como producto del aprendizaje en la práctica de enseñar matemáticas en profesores de primaria

Esta investigación estudia la identidad como producto del aprendizaje en la práctica situada de enseñar matemáticas de cuatro profesores de primaria en México. Las características de la identidad de “ser profesor de matemáticas” se infieren desde la trayectoria de formación y la práctica de los profesores. Los resultados indican que los profesores construyen y reconstruyen su identidad a partir de su práctica cotidiana lo que supone la negociación de maneras de realizar una práctica en un contexto a partir de tres aspectos: (i) El significado y sentido que los profesores atribuyen a las experiencias que acumulan en su trayectoria de formación, (ii) a la acción mediada con las tareas y los instrumentos que utilizan, y (iii) a la interacción entre el significado y sentido y la acción mediada al gestionar la clase de matemáticas.

μ-MAR: Multiplane 3D Marker based Registration for depth-sensing cameras

Many applications including object reconstruction, robot guidance, and. scene mapping require the registration of multiple views from a scene to generate a complete geometric and appearance model of it. In real situations, transformations between views are unknown and it is necessary to apply expert inference to estimate them. In the last few years, the emergence of low-cost depth-sensing cameras has strengthened the research on this topic, motivating a plethora of new applications. Although they have enough resolution and accuracy for many applications, some situations may not be solved with general state-of-the-art registration methods due to the signal-to-noise ratio (SNR) and the resolution of the data provided. The problem of working with low SNR data, in general terms, may appear in any 3D system, then it is necessary to propose novel solutions in this aspect. In this paper, we propose a method, μ-MAR, able to both coarse and fine register sets of 3D points provided by low-cost depth-sensing cameras, despite it is not restricted to these sensors, into a common coordinate system. The method is able to overcome the noisy data problem by means of using a model-based solution of multiplane registration. Specifically, it iteratively registers 3D markers composed by multiple planes extracted from points of multiple views of the scene. As the markers and the object of interest are static in the scenario, the transformations obtained for the markers are applied to the object in order to reconstruct it. Experiments have been performed using synthetic and real data. The synthetic data allows a qualitative and quantitative evaluation by means of visual inspection and Hausdorff distance respectively. The real data experiments show the performance of the proposal using data acquired by a Primesense Carmine RGB-D sensor. The method has been compared to several state-of-the-art methods. The results show the good performance of the μ-MAR to register objects with high accuracy in presence of noisy data outperforming the existing methods.

El traductor e intérprete emprendedor: análisis de la supervivencia de las empresas y los empresarios autónomos

This study presents an empirical analysis of the determinants of firm and self-employed survival in the Spanish translation sector. In the midst of a global downturn firm and self-employed survival is a key factor for the progress of the economies and for a better and more stable future. The study presents, first of all, a review of the literature on translation, interpreting, career opportunities, and entrepreneurship, and firm survival. The following empirical analysis explores the combination of variables of human capital, contingency and economic investment that potentially drive translation and interpreting firms or self-employed entrepreneurs to survive. The study performs a comparative qualitative analysis with a fs/QCA methodology identifying nine combination of causes that lead to the outcome. The results contribute towards a better understanding of entrepreneur translators’ lifespan as they provide an empirical outlook on the different causal paths that predict the survival of those translation and interpreting firms or self-employed entrepreneurs. The last part concludes with the most relevant findings of this research study. With little literature on the topic of firm survival in the translation and interpreting sector the paper aims to fill this gap and make a valuable contribution to the current literature on translation-firm creation and firm and self-employed survival.
