Prenatal exposure to diazepam and alprazolam, but not to zolpidem, affects behavioural stress reactivity in handling-naïve and handling-habituated ad…
2002
A gentle long-lasting handling produces persistent neurochemical and behavioural changes and attenuates the impairment in the behavioural reactivity to novelty induced by the prenatal exposure to diazepam (DZ) in adult male rat progeny. This study investigated the consequences of a late prenatal treatment with three GABA/BDZ R agonists (DZ) alprazolam (ALP) and zolpidem (ZOLP)), on different stress-related behavioural patterns, in non-handled (NH), short-lasting handled (SLH) and long-lasting handled (LLH) adult male rats exposed to forced swim test (FST), acoustic startle reflex (ASR) and Vogel test (VT). The effects on motor activity were evaluated in the open field and in the Skinner box…
Are importing and exporting complements or substitutes in an emerging economy? The case of Colombia
2021
The aim of this paper is to investigate the impact of two trading strategies (exporting and importing) on total factor productivity (TFP) and the potential complementarity/substitutability effects of these strategies. In order to assess these effects, robust estimates of TFP are obtained using a general method of moments approach that explicitly determines the ability of a firm's trading experience to affect productivity. Data from the Annual Manufacturing Survey spanning from 2007 to 2016 is used for Colombian manufacturing firms. Our estimation results suggest that, regardless of the technological intensity of the industry in which the firm operates, active trading strategies (exporting o…
Essays on Digitalization and Firm Performance
2023
Esta tesis doctoral analiza cómo el uso de las tecnologías digitales (TD) afecta las decisiones de las empresas en el comercio internacional y el empleo. La rápida expansión de estas tecnologías ofrece oportunidades para reducir costes asociados a la distancia física, lo que permite a las empresas llegar a más clientes y ampliar sus mercados. Sin embargo, el hecho de que las TD también puedan ser sustitutas de la mano de obra, remplazando a los humanos en sus trabajos y aumentando potencialmente el desempleo, suscita preocupación. Así pues, estos dos temas serán abordados en la tesis. Primer, los Capítulos 1 y 2 se centrarán en el impacto de la digitalización en el comercio internacional. M…

Manufacturing export performance and public capital: an analysis by country technology position
2021
The objective of this paper is to examine the relationship between public capital and manufacturing export performance. It also aims at investigating whether this relationship depends on the proximity of a country's technology frontier. To achieve this, we adopted a methodology that estimates the elasticities of public capital as a non-rival factor in a model that considers factor intensity as a mechanism of industrial development. We use an interaction model with panel data from 1999 to 2014 across 35 advanced and less advanced countries. Our results show that in countries far from the technology frontier, public capital accumulation is an element of industrial development as opposed to co…
'I Show Off, Therefore I Am': The Politics of the Selfie
2016
International audience; Named word of the year by the OED in 2013, the “selfie” is a worldwide phenomenon. Many see these digital self-portraits as markers for the spread of narcissism or signs of the blurring of limits between the public and private spheres. Initially popular with young people, selfies were soon adopted by politicians who, in a mediatized society, are eager to adhere to new vogues and use digital trends to self-promote. Like “digital natives”, they attempt to go viral by turning their cellphones on themselves and tweeting. Contrary to more formal images (official portraits, campaign posters) where politicians are clearly packaged and marketed, self-snapped photos taken on …
Estar al otro lado de la mesa. Profesionales de los servicios públicos de empleo ante los dilemas de la activación laboral
2019
Under the paradigm of activation, the Public Employment Services has been reshaped by two levels of contractualization. On one hand, the collaboration of the administration with a network of agents on the programme scheme that make up the active policies of employment. On the other hand, the unemployed person?s access to a compartmentalized offer of services and individually taking responsibility for finding work. This double contractualization reveals redefinition of lowering public responsibility faced with the problem of unemployment that this activation supposes. This paper analyses how this redesign has an impact on how professionals serve the unemployed population. This lays bare, in …
Communication et médiation par le toucherdans quelques expositions de sciences : Limites et contraintes dans l’expérience des visiteurs
2016
This communication deals with the “general public” of visitors to a number of interactive exhibits that accord a direct or indirect role to the sense of touch in knowledge mediation and interpretation. The role of touch is discussed in terms of its limitations and constraints in communication situations. The social mobilizations of touch are not immediately evident; what are the conditions under which visitors actually use touch in experiencing an exhibit? What connections with other signifiers are the most conducive to reception? This qualitative research relies on observation and interviews. Apprehension of interactive objects appears to be dependent on the surrounding setting of sociabil…
Educación artística : revista de investigación
2014
Resumen basado en el de la publicación Título, resumen y palabras clave también en inglés Se hace una aproximación a una de las últimas obras de Joan Fontcuberta, fotógrafo y artista internacional caracterizado por jugar a menudo con las prácticas documentales, llevando al límite la veracidad de la narración y articulando la representación para ponerla en evidencia. Se basa en la colección de imágenes fotográficas particulares encontradas en Internet y que formaron parte de una muestra itinerante realizada entre 2012 y 2013. Se combina una conversación con el artista y una reflexión que puede ayudar a situar la autoría, la veracidad fotográfica y la identidad entorno la conjetura actual y a…
: in Musées :on rénove !
2003
L'article analyse la manière dont les musées esquivent dans leur exposition le plus souvent les sujets dérangeants, notamment les questions politiques sensibles, telle la question de la mémoire ouvrière le plus souvent au profit d'une mise en valeur des techniques et des savoir-faire.
