Electronic surveillance in the couple: The role of self-efficacy and commitment
2021
Abstract Researchers have shown a significant effect of using social networking sites (SNSs) on romantic relationships. Surveillance is one of the motives for social network use. Social networking surveillance is related to controlling a romantic partner's online behaviours. The purpose of the study was to search for antecedents of electronic surveillance (Study 1) and to examine their role in behaviours related to electronic surveillance among romantic couples (Study 2). Following the uses and gratification theory and technology acceptance model of using SNSs, antecedents of electronic surveillance in adult Facebook users were examined. In Study 1, the relationship between electronic surve…
Experiences in Digital Video Composition as Sources of Self-Efficacy Toward Technology Use
2018
As teachers’ self-efficacy has been shown to be a crucial factor in technology integration, there is a need to understand the mechanisms that may raise teachers’ self-efficacy toward technology integration. This article seeks to understand what sources of self-efficacy hands-on experiences with technology may provide to pre-service teachers. The participants were 37 students who were taking a course on digital literacies, where they composed a digital video in small groups. The data consists of students’ individually written post-course self-evaluation reports. In the analysis of the reports, the authors identified text fragments that indicated either 1) sources of self-efficacy related to …
Recognizing actions with the associative self-organizing map
2013
When artificial agents interact and cooperate with other agents, either human or artificial, they need to recognize others’ actions and infer their hidden intentions from the sole observation of their surface level movements. Indeed, action and intention understanding in humans is believed to facilitate a number of social interactions and is supported by a complex neural substrate (i.e. the mirror neuron system). Implementation of such mechanisms in artificial agents would pave the route to the development of a vast range of advanced cognitive abilities, such as social interaction, adaptation, and learning by imitation, just to name a few. We present a first step towards a fully-fledged int…
A multiscale approach to automatic and unsupervised retinal vessel segmentation using Self-Organizing Maps
2016
In this paper an automatic unsupervised method for retinal vessel segmentation is described. Self-Organizing Map, modified Fuzzy C-Means, STAPLE algorithms and majority voting strategy were adopted to identify a segmentation of the retinal vessels. The performance of the proposed method was evaluated on the DRIVE database.
Marte Meo as a port of entry to parental sensitivity - a three–case study
2019
Abstract Background Early parent- child relations play an important role in children’s development. Therapeutic intervention towards infants and toddlers at high-risk intends to prevent mental health problems. In this work, the parent-child-dyad is crucial. The video interaction guidance method, Marte Meo, is one among different methods used in attachment-based treatment in an outpatient infant mental health clinic. Parental sensitivity towards infants and toddlers needs is considered significant in developing secure attachment. Secure attachment is further considered decisive for mental health and the extent to which children are at risk of developing mental health problems. Different trea…
First-Principles Calculation of Electroweak Box Diagrams from Lattice QCD.
2020
We present the first realistic lattice QCD calculation of the $\gamma W$-box diagrams relevant for beta decays. The nonperturbative low-momentum integral of the $\gamma W$ loop is calculated using a lattice QCD simulation, complemented by the perturbative QCD result at high momenta. Using the pion semileptonic decay as an example, we demonstrate the feasibility of the method. By using domain wall fermions at the physical pion mass with multiple lattice spacings and volumes, we obtain the axial $\gamma W$-box correction to the semileptonic pion decay, $\Box_{\gamma W}^{VA}\big|_{\pi}=2.830(11)_{\mathrm{stat}}(26)_{\mathrm{sys}}\times10^{-3}$, with the total uncertainty controlled at the leve…
Spin–isospin excitations probed by strong, weak and electro-magnetic interactions
2011
Abstract Gamow–Teller (GT) transitions are the most common weak interaction processes of spin–isospin ( σ τ ) type in atomic nuclei. They are of interest not only in nuclear physics but also in astrophysics; they play an important role in supernovae explosions and nucleosynthesis. The direct study of weak decay processes, however, gives relatively limited information about GT transitions and the states excited via GT transitions (GT states); β decay can only access states at excitation energies lower than the decay Q -value, and neutrino-induced reactions have very small cross-sections. However, one should note that β decay has a direct access to the absolute GT transition strengths B (GT) …
Bayesian Analysis of a Future Beta Decay Experiment's Sensitivity to Neutrino Mass Scale and Ordering
2021
Bayesian modeling techniques enable sensitivity analyses that incorporate detailed expectations regarding future experiments. A model-based approach also allows one to evaluate inferences and predicted outcomes, by calibrating (or measuring) the consequences incurred when certain results are reported. We present procedures for calibrating predictions of an experiment's sensitivity to both continuous and discrete parameters. Using these procedures and a new Bayesian model of the $\beta$-decay spectrum, we assess a high-precision $\beta$-decay experiment's sensitivity to the neutrino mass scale and ordering, for one assumed design scenario. We find that such an experiment could measure the el…
SYMBOLIC INTERACTIONS:TOWARDS A COGNITIVE SCIENTIFIC THEORY OF MEANING IN HUMAN TECHNOLOGY INTERACTION
2015
Information technology has perpetuated the role of symbolism in everyday life practice, through its reliance on sign systems for its creation and operation. Increasingly attention has been placed on applying semiotic techniques to analyze user interface design and usability. Surprisingly, although the move towards symbolic interaction has been one of the most striking components of the digital shift, it has proven difficult to build bridges between semiotics and HTI-design thinking. In this article we argue that the problems in linking semiotic analysis of human technology interaction with modern HTI-design paradigms such as usability or user experience arise from a theoretical gap between …
Penser l'altérité : de l'expérience sensible à la figure sensible de l'étranger
2016
International audience; La figure de l’étranger est une figure qui puise son sens dans une relation d’altérité familiarisée. De Simmel (1908) à Ricœur (1990) ou à Todorov (1989), l’étranger est cet Autre proche, qui renvoie en négatif à un Je ou à un Nous qui se construit dans la différence. Rêvée, recherchée, fantasmée, crainte, fuie ou haïe, la figure de l’étranger peut condenser toutes les aspirations et toutes les peurs. L’ambition de ce chapitre est de mieux comprendre les mécanismes représentationnels associés à cette figure bien particulière. Comment influencent-ils nos interactions sociales avec des « étrangers » ? Comment la figure sensible de l’étranger se déploie-t-elle au quotid…
