The Elephant in the Machine: Proposing a New Metric of Data Reliability and its Application to a Medical Case to Assess Classification Reliability
2020
In this paper, we present and discuss a novel reliability metric to quantify the extent a ground truth, generated in multi-rater settings, as a reliable basis for the training and validation of machine learning predictive models. To define this metric, three dimensions are taken into account: agreement (that is, how much a group of raters mutually agree on a single case)
Individualizing deep dynamic models for psychological resilience data
2020
ABSTRACTDeep learning approaches can uncover complex patterns in data. In particular, variational autoencoders (VAEs) achieve this by a non-linear mapping of data into a low-dimensional latent space. Motivated by an application to psychological resilience in the Mainz Resilience Project (MARP), which features intermittent longitudinal measurements of stressors and mental health, we propose an approach for individualized, dynamic modeling in this latent space. Specifically, we utilize ordinary differential equations (ODEs) and develop a novel technique for obtaining person-specific ODE parameters even in settings with a rather small number of individuals and observations, incomplete data, an…
Comunicación digital y líneas de fractura en el paradigma de la agenda setting
2006
En: Doxa Comunicación : revista interdisciplinar de estudios de comunicación y ciencias sociales. ISSN 1696-019X n. IV, 2006, pp 37-58 Propone realizar una prospectiva que arroje alguna luz sobre las modificaciones que puede sufrir la teoría de la Agenda Setting, e incluso, eventualmente, su superación, por efecto del desarrollo de los sistemas de comunicación digital. La hipótesis de la que partimos es la de que, si bien la multiplicación y diversificación de medios de comunicación provocada por las tecnologías digitales no tiene por qué haber supuesto, hasta el momento, una diversificación de similar calado en lo que concierne a los temas de interés informativo sancionados por los medios,…
Propiedades psicométricas del Cuestionario de conciencia emocional en población infantil española
2016
La competencia emocional es la capacidad para percibir, expresar, comprender, regular y controlar nuestras emociones y las de los demás. La conciencia emocional es la competencia básica que permite el desarrollo del resto de competencias emocionales durante la infancia y la adolescencia. En este trabajo, se han estudiado las propiedades psicométricas de la versión española del Cuestionario de conciencia emocional, administrado a 1476 niños/as españoles (8-12 años). Se ha replicado la estructura original formada por seis factores. Se han estudiado la fiabilidad de los ítems y del instrumento, la validez de constructo, de contenido y concurrente, los resultados han sido satisfactorios. Se han…
Primary Student-Teachers' Conceptual Understanding of the Greenhouse Effect: A Mixed Method Study
2011
International audience; The greenhouse effect is a reasonably complex scientific phenomenon which can be used as a model to examine students' conceptual understanding in science. Primary student-teachers' understanding of global environmental problems, such as climate change and ozone depletion, indicates that they have many misconceptions. The present mixed methods study examines Finnish primary student-teachers' understanding of the greenhouse effect based on the results obtained via open-ended and closed-form questionnaires. The open-ended questionnaire considers primary student-teachers' spontaneous ideas about the greenhouse effect depicted by concept maps. The present study also uses …
The Good Parent: Southern Italian Mothers’ Conceptualization of Good Parenting and Parent–Child Relationships
2019
Thirty mothers, ranging in age between 30 and 46 years, participated in seven focus groups aimed at analyzing perceptions and ideas of the characteristics of a good parent and parent–child relationship in southern Italy (Sicily). The discussions were transcribed and analyzed using the constant comparative analysis approach. Two major themes, discipline and affection, emerged from the discussions about the idea of a good parent, with seven further subthemes. In defining good parenting beliefs and practices, Sicilian mothers mostly believed that control, discipline, and demandingness were imperative and prioritized over warmth and responsiveness. Despite the importance given to demandingness…
Winning the hearts and minds of followers: The interactive effects of followers' emotional competencies and goal setting types on trust in leadership
2015
La confianza de los seguidores es un elemento esencial de un liderazgo eficaz. Las aproximaciones tempranas a la formación de la confianza hacia los líderes, adoptaron un enfoque basado en evaluaciones basadas en información. Sin embargo, avances recientes en la investigación de la confianza sugiere que estas evaluaciones también contienen un componente afectivo. En este estudio proponemos que las competencias emocionales, como (1) atención, (2) claridad y (3) reparación emocional predecirán la confianza hacia el líder en momentos tempranos de la relación líder-seguidor. A medida que esta relación se desarrolla en el tiempo, las evaluaciones sobre la fiabilidad del líder cambiaran su objeti…
Consumo y medio ambiente en el País Valenciano (1980-2000)
2006
At the end of the 1970s, after more than a decade of intense economic development, some marks of the mass consumption model were engraved in the Valencian society: a commercialisation system increasingly dominated by large corporations which trade in worldwide markets and use massive advertising; an animal-protein based diet, with products imported from far-away countries, with a strong presence of highly processed and packaged food and beverage; mobility based on cars; preference for owned housing, sub-urbanisation tendency, and growing energy use; «use-and-dump» culture defined by short life of products and high production of waste. This consumption model is highly homogenous and indicate…
Viable Systems Approach and Consumer Culture Theory: A Conceptual Framework
2013
The aim of this study is to depict the relational dynamics between the firm/ brand and the individual/consumer or communities of consumers. To this aim we propose a conceptual framework, integrating the viable systems approach (VSA) with consumer culture theory (CCT), which considers the individual as an active co-maker of the product/brand (‘prosumer’). The VSA view of the firm overcomes the limitations of CCT research, which is mainly focused on the individual, giving little consideration to the other actors in the context. Among the different approaches under the umbrella of viable systems we chose the VSA because of its emphasis on the analysis of the systemic external relations with th…
