Context–content systems of random variables : The Contextuality-by-Default theory
2016
Abstract This paper provides a systematic yet accessible presentation of the Contextuality-by-Default theory. The consideration is confined to finite systems of categorical random variables, which allows us to focus on the basics of the theory without using full-scale measure-theoretic language. Contextuality-by-Default is a theory of random variables identified by their contents and their contexts, so that two variables have a joint distribution if and only if they share a context. Intuitively, the content of a random variable is the entity the random variable measures or responds to, while the context is formed by the conditions under which these measurements or responses are obtained. A …
Social Collaborative Viewpoint Regression with Explainable Recommendations
2017
A recommendation is called explainable if it not only predicts a numerical rating for an item, but also generates explanations for users' preferences. Most existing methods for explainable recommendation apply topic models to analyze user reviews to provide descriptions along with the recommendations they produce. So far, such methods have neglected user opinions and influences from social relations as a source of information for recommendations, even though these are known to improve the rating prediction. In this paper, we propose a latent variable model, called social collaborative viewpoint regression (sCVR), for predicting item ratings based on user opinions and social relations. To th…
Internet Adoption at the User Level: Empirical Evidence from The Gambia
2014
The unified theory of acceptance and use of technology (UTAUT) are used to investigate technology adoption. However, its application in Sub-Saharan Africa is rare and barely extended to the validation phase. In this paper, we introduce six new moderating factors for UTAUT core determinants and two other direct determinants of Internet adoption. The objective of this approach is to identify relevant elements of Internet adoption at the user level in The Gambia. Moderating factors are interacting terms used when the relationship between independent and dependent variable is weak, inconsistent or non-existent. A case study research design was employed and the data were gathered in Autumn of 20…
Early Oral Language Comprehension, Task Orientation, and Foundational Reading Skills as Predictors of Grade 3 Reading Comprehension
2016
The present five-year longitudinal study from preschool to grade 3 examined the developmental associations among oral language comprehension, task orientation, reading precursors, and reading fluency, as well as their role in predicting grade 3 reading comprehension. Ninety Finnish-speaking students participated in the study. The students’ oral language comprehension (vocabulary knowledge, listening comprehension, and inference making) and task orientation were assessed in preschool, kindergarten, and grade 3. Reading precursors (letter knowledge and phonological awareness) were assessed at the first two timepoints and reading fluency at the third timepoint. Structural equation modeling sho…
Incompiuto, una nuova linea di partenza : progettare la differenza per un futuro sostenibile
2020
Le contemporanee costruzioni incompiute, fattispecie diffusa globalmente dell’ambiente costruito in abbandono, solo di recente sono uscite dal tabù in cui le relega l’ineludibile condizione di epifania di un fallimento. Senza entrare nel merito dei significati teoretici ad esse attribuiti (oscillanti tra i poli sovente mistificatori dell’esaltazione e della demonizzazione) e guardando alle tendenze individuabili in alcune realizzazioni degli ultimi lustri, l’articolo intende contribuire alla definizione di un approccio analitico e progettuale orientato ai multidimensionali obiettivi della sostenibilità, per rispondere in modo concreto a molteplici portatori di interesse e istanze della coll…
Motivos de uso de las redes sociales virtuales: Análisis de perfiles de mujeres rurales
2015
En el presente trabajo, se muestran los resultados de una investigación cuyo objetivo es conocer los motivos de uso de las redes sociales virtuales de las mujeres rurales y determinar perfiles en función de sus respuestas. Para ello, se realiza un estudio de encuesta, cuyo cuestionario se aplica a 478 mujeres de entornos rurales de Andalucía de 18 a 65 años. Los resultados muestran dos perfiles de mujeres en función de sus motivaciones de uso de las redes, encontrando que las que usan las redes con una mayor variedad de motivos, muestran mayores niveles en intensidad, habilidad y autonomía de uso, mientras que las que la usan exclusivamente por motivos relacionales presentan niveles inferio…

Estudio de la relación entre la dificultad quirúrgica en la exodoncia del tercer molar y las variables clínicas y séricas.
2017
Título: ESTUDIO DE LA RELACIÓN ENTRE LA DIFICULTAD QUIRÚRGICA DEL TERCER MOLAR Y LAS VARIABLES CLÍNICAS Y SÉRICAS. La exodoncia del tercer molar es actualmente, uno de los procedimientos más importantes en la clínica diaria odontológica. Debemos de tener en cuenta la dificultad quirúrgica que podamos encontrarnos previa o durante el acto quirúrgico. Por lo que la valoración de la dificultad quirúrgica previa tanto clínica como radiográfica, sea un acto fundamental. Tras la exodoncia de tercer molar, en mayor o menor medida, aparecen complicaciones postoperatorias como es el dolor, inflamación y trismo; generándose tras la exodoncia un cuadro de inflamación aguda, que puede estar influenciad…
E-Sports y brecha de género: la percepción de las profesionales españolas
2019
The present paper aims to identify the causes of under-representation of women in E-sports. According to a genre perspective, interest in videogames at the amateur level is quite similar. However, in its professional level, female participation becomes very limited. The fact that physical effort is irrelevant (a requirement for ?traditional sports?) could be considered a variable that would negatively affect greater to equality in the conditions of access and participation of women in electronic sports. Against any predictions, the data on the presence of women are elocuent: few women, with much lower wages than men to remunerate same skills, and a general complaint by the female profession…
Self-reported reflective functioning mediates the association between attachment insecurity and well-being among psychotherapists.
2020
Objective: Subjective well-being is a crucial variable for mental health practitioners. This study examines the influence of therapists’ attachment dimensions and self-reported reflective functioning on their perceived well-being. Further, it examines if reflective functioning mediates the association between attachment insecurity and well-being. Method: A total of 416 experienced psychotherapists were enrolled in this cross-sectional study, and completed self-report measures of attachment insecurity, reflective functioning, and well-being. We tested the hypothesized mediation model with path analysis that examined indirect effects. Results: Both attachment anxiety and avoidance dimensions …
