BUSCADOR RECOLECTA

D’acord amb les teories Duvergerianes a llarg termini només els partits polítics viables s’haurien de presentar en solitari a les eleccions, mentre que els partits no viables haurien de crear coalicions preelectorals o retirar-se de la competició. Tanmateix, partits no viables d’arreu del món continuen presentant candidatures, posant en qüestió les teories Duvergerianes. Partint de la paradoxa que més partits dels que és esperat presenten candidats, argumento que la superposició d’arenes electorals genera oportunitats per partits viables perquè presentin candidatures en arenes on no són viables. Mitjançant entrevistes en profunditat a líders polítics del Canadà i d’Espanya mostro com la superposició d’arenes electorals ha convertit la decisió de presentar candidatures quan no s’és viable en l’estratègia dominant, mentre que crear coalicions o retirar-se de la competició són alternatives subòptimes. Aquesta situació porta a un excés d’oferta de partits polítics competint en comparació amb el que les teories de Duverger prediuen. Mitjançant una anàlisi comparada amb dades per 46 països analitzo els mecanismes institucionals i sociològics que expliquen variació en el nombre de partits polítics que competeixen quan no són viables

Sample of 3,730 journal articles published by authors from Catalonia's CERCA research centres between 2011 and 2015 and available on Web of Science (out of a total output of 44,423) identifying how many were available in open access, full-text format. The results revealed that 75,8% of the total (2,828 articles) had at least one version available in open access, but just 52% (1,940 articles) had at least one version available in either journals (whether pure or hybrid open access journals or those with embargo periods) or repositories, a finding that highlights the powerful role played by academic social networks in the sharp increase in open access availability. Of the 2,828 articles for which at least one open access version was found, a total of 9,868 copies were located. With respect to versions, the publisher’s final version, i.e. the type formatted for publication by journal publishers, was found in 75,3% of cases. The number of articles published in open access journals (567) was very close to the number of articles published in hybrid journals or journals with embargo periods (624). Only 40,4% of the articles in the sample were located in repositories, being the subject repositories the heaviest used. Fifty percent of the articles (1,881 publications) were posted on academic social networks, the most popular of which were ResearchGate and Academia. According to thematic areas, all six areas (science, life sciences, medical and health sciences, engineering and architecture and humanities) exceeded 70% of articles in open access.
