Spatial productivity spillovers across Spanish municipalities

Whilst a great deal of e¤ort has been dedicated to identification of agglomeration effects on labour productivity, the measurement of spatial productivity spillovers is a question that has been addressed only occasionally along the New Economic Geography literature. We estimate agglomeration effects, nonetheless conditioned to the possible existence of spatial productivity spillovers across Spanish municipalities in year 2001. To this respect, we find that agglomeration effects are in the same order of magnitude than thoseencountered when measured in the standard way. Further, these agglomeration efects coexist with very strong spatial productivity spillovers in a close neighbourhood of 10 km. Finally, these spatial e¤ects are shown to quickly diminish as distance increases.IV estimation, elevation, spatial externalities, productivity, neighbourhood, Spain

Imaging sub-milliarcsecond stellar features with intensity interferometry using air Cherenkov telescope arrays

Recent proposals have been advanced to apply imaging air Cherenkov telescope arrays to stellar intensity interferometry (SII). Of particular interest is the possibility of model-independent image recovery afforded by the good (u, v)-plane coverage of these arrays, as well as recent developments in phase retrieval techniques. The capabilities of these instruments used as SII receivers have already been explored for simple stellar objects, and here the focus is on reconstructing stellar images with non-uniform radiance distributions. We find that hot stars (T > 6000 K) containing hot and/or cool localized regions (T \sim 500 K) as small as \sim 0.1 mas can be imaged at short wavelengths ({\lambda} = 400 nm).Comment: Accepted for publication in MNRAS. 6 pages, 10 figure

El ejercicio del poder en las relaciones femeninas: Los métodos de coerción en el cine de convento.

Desde los orígenes del cine, las temáticas relativas al poder y la aplicación de la autoridad han poblado la cinematografía de cineastas de todas las épocas y regiones del mundo.En este recorrido, sin embargo, se ha producido una clara tendencia a mostrar principalmente la perspectiva masculina del poder y la manera en que el hombre, en particular, se vincula con la autoridad. Este artículo se propone indagar en una perspectiva menos visibilizada, como es la femenina, de modo de conocer cómo funciona el ejercicio del poder específicamente en las relaciones entre mujeres, a través del cine. Para esto, se realizó un análisis-ensayo de la película La Religieuse (2013) de Guillaume Nicloux, la que fue examinada a la luz del texto de Michael Foucault Vigilar y Castigar (1975). Las conclusiones indican que los métodos de coerción y disciplina funcionan de manera relativamente transversal en cualquier tipo de dinámica interpersonal, que la observación jerarquizada y la vigilancia mutua representan un efectivo recurso a la hora de mantener el control de un sistema, pero que además, el ejercicio del poder es también una relación cambiante que forma parte de una maquinaria que excede las posibilidades de cada individuo

The European Map of Job Flows

The European Map of Job Flows (EMJF) is a term used to denote a dataset of meso- and macro-level variables describing different aspect of labour mobility within national labour markets in Europe. In this paper, EMJF is centred on the notion of job “flows”, namely the changes in the level of employment at different breakdowns and levels of aggregation. EMJF is very rich in information content due to the wide variety of possible breakdown of the data and in this sense it is a “map” mostly in the virtual sense, namely, that it is not possible to visualise in the form of geographic maps all the wealth of available information. In terms of its value as a research product and tool, EMJF is mostly an intermediate product in the sense that it is a convenient means to organise the relevant information, which could subsequently be used for different analytical and research purposes. It provides both for cross-sections/snapshots of job flows at different point in time but also it allows their assessment and analysis over longer periods of time. In this sense, EMJF can be widely used for various types of labour-market analysis and research. EMJF’s visual components can also be a convenient tool for policy makers dealing with labour market policies at different level (regional, national or supra-national) in the decision-making process. Here we present a Compilation of a EMJF on the basis of firm-level data In this sense the job flows are built up on the basis of firm-level data for individual countries, following a common methodology. We adopt an approach of establishing such a EMJF on the basis of the AMADEUS dataset developed by the consultancy Bureau van Dijk. The dataset in its most extended version contains balance sheet data and ownership data for almost 14 million firms from 43 different European countries (September 2009 update). For many EU countries the dataset has in principle access to the entire universe of firms which have to report a balance sheet. In terms of countries, the geographic coverage of AMADEUS encompasses information for all the 27 members of the European Union (albeit with different qualities in terms of national coverage) as well as other 16 European countries that complete the geographical and political definition of the continent. Another interesting feature of the database is given by the detailed definition of a firm's location, with data available on the region (NUTS2) and the city in which the firm operates. This project deliverable presents the main results from the final stage of MICRO-DYN work on the EMJF. It discusses the approach to building the EMJF on the basis of AMADEUS data and illustrates the analytical potential of the EMJF as a research tool with a range of Europe-wide analytical exercises. Probably the most important outcome of this research effort is the demonstrated capability to perform meta-analysis at the European level of important labour market characteristics on the basis of firm-level data.job flows, europe, labor market, microdata

La micronarrativa como manifestación de la estética posmoderna y sus alcances para la comunicación publicitaria actual.

El presente artículo aborda el fenómeno de la micronarrativa como exponente perfecto de la estética posmoderna. A partir del análisis de las características esenciales del género, se destacan las virtudes del microrrelato y su capacidad para im- pactar de manera novedosa y atractiva al lector de hoy, especialmente a través del medio digital. Esta facultad de la forma breve resulta de gran valor para la comunicación publicitaria, industria que desde sus orígenes ha debido ajustarse a las restricciones de tiempo y exposición que afectan a sus anuncios, y que ha encontrado en la micronarrativa un aliado fundamental para llegar al público objetivo de for- ma clara y efectiva. A modo de aplicación, se realiza una reseña y un breve análisis a la campaña titula- da; ‘Escribamos juntos esta historia’, de Movistar de Chile, en el 2017, en que aplican los conceptos del microrrelato; hiperbrevedad, fragmentariedad, in- tertextualidad, metarrelato y la autorreferenciali- dad. La discusión inicia con la atención y retención de los mensajes y se concluye en lo que respecta a la publicidad audiovisual, queda la sensación de que la micronarrativa como tal no ha sido explotada en todo su vigor

Cognitive reserve mediates the severity of certain neuropsychological deficits related to cocaine use disorder

Introduction: The concept of cognitive reserve (CR) is being considered in the field of substance use disorder (SUD) by observing that there are individuals whose brain alterations are not related to the cognitive symptomatology they present. Aims: Our aims were to characterise the possible neuropsychological deficits in a sample of subjects with SUD compared to a control group and to determine whether the degree of CR is a mediator in the cognitive functioning of these patients. Methods: To perform these objectives, the study involved a sample of subjects with SUD in outpatient treatment and a control group. A CR questionnaire and a comprehensive neuropsychological assessment were administered, and we also collected data related to drug consumption and psychological well-being. Results: The SUD group showed poorer performance compared to the control group in several cognitive domains (attention, declarative memory, executive functions and emotional perception), as well as in psychological comfort. Interestingly, we observed that the deficits found in attention, declarative memory and executive functions were mediated by the CR level of the participants, an effect that we did not observe in the rest of the variables registered. Conclusion: Our results suggest that long-term drug consumption leads to cognitive deficits and affects the psychological well-being of the subjects. Moreover, the CR should be taken into account during the assessment and rehabilitation of patients with SUD due to its protective role against certain neuropsychological deficits.Universidad de Málaga.
