    La peculiaridad constitutiva de las investigaciones en didáctica de las ciencias sociales reside en la «operatoriedad» tecnológica del proceso de enseñanza-aprendizaje, que implica una continuidad «substancial» entre las operaciones de los alumnos y los profesores. Investigar tales operaciones exige regresar a un plano «esencial» de explicación, sin eliminarlas ni perderlas de vista, sea porque somos capaces de subsumirlas en estructuras objetivas, sea porque regresamos desde las estructuras objetivas a las operaciones que la constituyen o bien porque somos capaces de analizar los procesos mediante los cuales unas operaciones determinan a otras operaciones del mismo campo didáctico.The constitutive peculiarity of research into the teaching of social sciences can be found in the technological “operative nature” of the teaching-learning process, which implies a «substantial» continuity between pupils’ operations and those of the teachers. To do research into such operations demands that we go back to an «essential» level of explanation, without either suppressing them or not keeping them in sight, be it because we are able to subsume them within objective structures, or be it because we return from objective structures to the operations that make it up, or because we are able to analyse the processes by means of which some operations determine others in the same educational field.La peculiaridad constitutiva de las investigaciones en didáctica de las ciencias sociales reside en la «operatoriedad» tecnológica del proceso de enseñanza-aprendizaje, que implica una continuidad «substancial» entre las operaciones de los alumnos y los profesores.

    A low-power reconfigurable ADC for biomedical sensor interfaces

    Get PDF
    This paper presents a 12-bit low-voltage low-power reconfigurable Analog-to-Digital Converter (ADC). The design employs Switched Capacitor (SC) techniques and implements a Successive Approximation (SA) algorithm. The ADC can be tuned to handle a large variety of biopotential signals, with digitally selectable resolution and input signal amplitude. It achieves 10.4-bit of effective resolution sampling at 56kS/s, with a power consumption below 3μW from a 1V voltage supply.Ministerio de Educación y Ciencia TEC2006-03022Junta de Andalucía TIC-0281

    Optimizing Player and Viewer Amusement in Suspense Video Games

    Get PDF
    Broadcast video games need to provide amusement to both players and audience. To achieve this, one of the most consumed genres is suspense, due to the psychological effects it has on both roles. Suspense is typically achieved in video games by controlling the amount of delivered information about the location of the threat. However, previous research suggests that players need more frequent information to reach similar amusement than viewers, even at the cost of jeopardizing viewers' engagement. In order to obtain models that maximize amusement for both interactive and passive audiences, we conducted an experiment in which a group of subjects played a suspenseful video game while another group watched it remotely. The subjects were asked to report their perceived suspense and amusement, and the data were used to obtain regression models for two common strategies to evoke suspense in video games: by alerting when the threat is approaching and by random circumstantial indications about the location of the threat. The results suggest that the optimal level is reached through randomly providing the minimal amount of information that still allows players to counteract the threat.We reckon that these results can be applied to a broad narrative media, beyond interactive games

    Justice, emotions and satisfaction in complaint behavior in services

    This study proposes a marketing approach to service recovery (SR) models in order to help to explain what factors affect cumulative satisfaction, loyalty and word-of-mouth following complaint behavior. The model has its base on the definition of perceived justice and its influence on satisfaction with service recovery (SSR) and on emotions (positive and negative). Trust acts as a central construct in the model, receiving influence from the affective and cognitive aspect and mediating the relationship between SSR and cumulative satisfaction and between positive/negative emotions and loyalty. The sample for this study consists of 303 Spanish B2C-EC users who made a complaint after an electronic transaction. Results from the analysis show the influence of perceived justice ?mainly interactional justice and procedural justice? on SSR, and the relevance of positive emotions as a key factor in SSR processes, in contrast to the major role which negative emotions have traditionally played in these models. Furthermore, trust mediates the relation between SSR and cumulative satisfaction, and is the factor which has a higher influence on loyalty, whilst cumulative satisfaction becomes the more relevant factor affecting WOM

    Successful loyalty in e-complaints: FsQCA and structural equation modeling analyses

    Get PDF
    An increasing number of consumers shift their buying activities from physical stores to retail websites. The reasons for this change are lower prices, time savings and a wider selection of products and services available on websites (Brunner et al., 2014). At the end of 2014, more than 3 billion people used Internet. In Europe 565 million people already use the Internet (79% of the population), and 47% make online purchases (Ecommerce Europe, 2014). Despite efforts by B2C e-commerce firms to offer high-quality services, providing a failure-free service proves almost impossible. Depending on how firms handle service recovery, results may vary massively: from losing an angry customer to retaining a satisfied who may still be willing to purchase again in the future

    Emotions in services: complaint in B2C e-commerce

    This study proposes a service recovery (SR) model to describe how cumulative satisfaction, loyalty and word-of-mouth are affected by complaints. The model is based on the role of positive and negative emotions in satisfaction with service recovery (SSR) processes. While prior SSR studies usually investigated only negative emotions and satisfaction with a specific transaction, this research considered both positive and negative emotions
