Interacción y símbolo en autistas

Resumen

El análisis del autismo, desde una perspectiva interaccionista, pone de manifiesto la falta de fundamento de muchas de las posiciones «cognitivistas» y «afectivistas», mantenidas tradicionalmente en la interpretación del sindrome, y la escasa eficacia de muchos procedimientos terapéuticos basados en tales interpretaciones. La comparación del desarrollo interactivo del niño normal con el del niño autista permite una interpretación más adecuada del sindrome y sugiere vías terapéuticas para su tratamiento eficaz.     

An organisational perspective on the cluster paradox: Exploring how members of a cluster manage the tension between continuity and renewal

Clusters face what has been referred to as a ‘cluster paradox’; a situation in which a collective identity breeds cohesion and efficiency in inter-organisational collaboration, yet it hinders the variety needed to adapt to disruptive change and prevent lock-in situations. Accordingly, a recurring theme in the literature on cluster evolution and cluster life-cycles is the need for constant renewal to allow clusters to adapt to a changing environment. However, how individual firms enact a process of cluster renewal and consider possible response options is not well understood. Using a French energy cluster as empirical setting, this paper investigates individual members’ enactment of the renewal in terms of how it could affect their current position, both structurally and relationally, and to what extent members felt that they had agency to steer the process to safeguard their position. The findings show that members’ enactment of the proposed change does not only depend on the perceived impact of cluster renewal on the member itself but also on the impact the renewal might have on other members in the firm’s network. The analysis also suggests that cluster renewal leads to a leadership vacuum where it is not clear who, if anyone, will lead the renewal process.     

The many faces of mobility: Using bibliometric data to measure the movement of scientists

This paper presents a methodological framework for developing scientific mobility indicators based on bibliometric data. We identify nearly 16 million individual authors from publications covered in the Web of Science for the 2008–2015 period. Based on the information provided across individuals’ publication records, we propose a general classification for analyzing scientific mobility using institutional affiliation changes. We distinguish between migrants--authors who have ruptures with their country of origin--and travelers--authors who gain additional affiliations while maintaining affiliation with their country of origin. We find that 3.7% of researchers who have published at least one paper over the period are mobile. Travelers represent 72.7% of all mobile scholars, but migrants have higher scientific impact. We apply this classification at the country level, expanding the classification to incorporate the directionality of scientists’ mobility (i.e., incoming and outgoing). We provide a brief analysis to highlight the utility of the proposed taxonomy to study scholarly mobility and discuss the implications for science policy.     

Comparing journal and paper level classifications of science

The classification of science into disciplines is at the heart of bibliometric analyses. While most classifications systems are implemented at the journal level, their accuracy has been questioned, and paper-level classifications have been considered by many to be more precise. However, few studies investigated the difference between journal and the paper classification systems. This study addresses this gap by comparing the journal- and paper-level classifications for the same set of papers and journals. This isolates the effects of classification precision (i.e., journal- or paper-level) to reveal the extent of paper misclassification. Results show almost half of papers could be misclassified in journal classification systems. Given their importance in the construction and analysis of bibliometric indicators, more attention should be given to the robustness and accuracy of these disciplinary classifications schemes.
