Unravelling environment and politics in the Spanish press. From Franco’s dictatorship to democracy
2017
The 1970s and 1980s were key years for the consolidation of environmentalism and environmental communication. In Spain, the special political situation during General Franco’s military dictatorship conditioned the coverage of environmental issues, as did the transition to democracy. The Albufera Natural Park (Valencia, Spain) was a particularly significant case in this context, since it was involved in one of the first environmental protests to protect a natural area covered by Spanish media. In this paper, we study opinion articles published in the Valencian newspapers Las Provincias and Levante, in order to analyze the evolution of the environmental discourse in Spanish society from the d…
Construction of an agglutination tool: recombinant Fab fragments biotinylated in vitro.
2009
The pComb3H vector system is used for constructing and panning recombinant antibody libraries. It allows for expression of monovalent Fab fragments, either on the surface of M13 phage, or in the form of soluble proteins secreted into the periplasmic space of bacteria. We constructed a modified pComb3H vector containing cDNA encoding for a 23-amino acid fragment of the Escherichia coli biotin carboxy carrier protein (BCCP), which is an acceptor sequence for biotinylation. The vector was used to express the Fab fragment recognizing human glycophorin A. The purified Fab fragment containing this biotin acceptor sequence was effectively biotinylated in vitro using biotin ligase (BirA). The speci…
Reactivación participativa del espacio público. Estudios de caso en Valencia y Madrid
2017
[EN] This work aims to understand the phenomenon of what we have propose to call "participatory reactivation of public space", which is characterized by the direct participation of citizens in the creation and management of social and cultural activities in public spaces, as part of a general will to reclaim that space as truly "public", where the citizens have power in the decision-making processes. This movement has been reinforced by the establishment of professional collectives and initiatives from public institutions. Seven case studies of organizations from Valencia and Madridwere conducted, in the form of semi-structured in-depth interviews,in order to define the shared characteristi…
La sociedad y el espacio público
2019
El espacio público y los actos de la propia sociedad, ¿hasta dónde llega el límite de unos para que comience el derecho de los otros? Son muchas las actuaciones que se suceden en la vía pública y que tienen una repercusión, en la mayoría de los casos, negativa para el paisaje urbano. En esta fina línea, entre la preservación del paisaje urbano y los derechos que la ley confiere a los ciudadanos, se enmarcan las ordenanzas de convivencia ciudadana como el mecanismo adecuado que normativice las conductas que inciden en el espacio público. Se juzga imprescindible analizar las normas de convivencia que presiden nuestro país, a fin de dar con soluciones ecuánimes que garanticen la viabilidad de …
Volver al sentido de la ciudad. Reflexiones hermenéuticas y éticas
2020
El propósito de esta contribución es delinear las principales reflexiones sobre la ética de ciudad surgidas en los últimos años. Para ello se abordan, en primer lugar, las conexiones entre racionalidad práctica, urbanismo y espacio público desde la perspectiva del pragmatismo crítico y de la ciencia social fronética. Estas propuestas nos proporcionan el marco hermenéutico para presentar a continuación algunas de las aproximaciones éticas más relevantes que pueden aplicarse a las ciudades actuales: la ética de las virtudes urbanas, el derecho a la ciudad, el movimiento de la ciudad justa, el giro urbano de la ética, la ética del ambiente construido, la ética del diseño y la conducta medioamb…
User acceptance of automated public transport
2020
Abstract Autonomous driving is receiving increasing attention in the automotive industry as well as in public transport. However, it is still unclear whether users are willing to use automated public transportation at all. In order to answer this and other questions, the transport company of the city of Mainz, Germany, tested the autonomous minibus EMMA (Elektro-Mobilitat Mainz Autonom) on a 600-meter-long test track in public space. The study presented here was conducted with the aim of exploring crucial determinants for the use of an autonomous minibus. On the basis of established acceptance models, a questionnaire was developed, which was completed in a field survey by a total of 942 par…
The language of emotion in short blog texts
2008
Emotion is central to human interactions, and automatic detection could enhance our experience with technologies. We investigate the linguistic expression of fine-grained emotion in 50 and 200 word samples of real blog texts previously coded by expert and naive raters. Content analysis (LIWC) reveals angry authors use more affective language and negative affect words, and that joyful authors use more positive affect words. Additionally, a co-occurrence semantic space approach (LSA) was able to identify fear (which naive human emotion raters could not do). We relate our findings to human emotion perception and note potential computational applications.
Computational Limitations of Affine Automata
2019
We present two new results on the computational limitations of affine automata. First, we show that the computation of bounded-error rational-values affine automata is simulated in logarithmic space. Second, we give an impossibility result for algebraic-valued affine automata. As a result, we identify some unary languages (in logarithmic space) that are not recognized by algebraic-valued affine automata with cutpoints.
Effectiveness of Data-Driven Induction of Semantic Spaces and Traditional Classifiers for Sarcasm Detection
2019
Irony and sarcasm are two complex linguistic phenomena that are widely used in everyday language and especially over the social media, but they represent two serious issues for automated text understanding. Many labeled corpora have been extracted from several sources to accomplish this task, and it seems that sarcasm is conveyed in different ways for different domains. Nonetheless, very little work has been done for comparing different methods among the available corpora. Furthermore, usually, each author collects and uses their own datasets to evaluate his own method. In this paper, we show that sarcasm detection can be tackled by applying classical machine learning algorithms to input te…
Facebook’s ad hoc groups: a potential source of communicative power of networked citizens
2017
Ad hoc groups (sporadically formed on social network sites for achieving particular common objectives) have been seen as a public space for citizen participation and debate. This study focuses on Facebook’s ad hoc groups in Finland. The aim is to detect the potential of these groups to enhance networked citizens’ communicative power for raising societally important issues to public agenda and initiate changes in society. We suggest a categorization of the groups according to their missions, and present their members’ specific motivations and objectives through an online survey. Despite the general entertainment-orientation and self-referential nature of social media, the results show that a…
