Preliminary evaluation of an analog procedure to assess acceptability of intimate partner violence against women: The Partner Violence Acceptability …

2015

Acceptability of partner violence against women is a risk factor linked to its perpetration, and to public, professionals’ and victims’ responses to this behavior. Research on the acceptability of violence in intimate partner relationships is, however, limited by reliance solely on self-reports that often provide distorted or socially desirable accounts that may misrepresent respondents’ true attitudes. This study presents data on the development and initial validation of a new analog task assessing respondents’ acceptability of physical violence toward women in intimate relationships: the Partner Violence Acceptability Movie task (PVAM). This new analog task is intended to provide a more i…

Performance analysis in sport: Contributions from a joint analysis of athletes’ experience and biomechanical indicators

2011

The purpose of this study was to test the usefulness of combining two types of analysis to investigate sports performance with the aim of optimizing it. These two types of analysis correspond to two levels of athletes’ activity: (a) their experiences during performance and (b) the biomechanical characteristics of their movements. Rowing served as an illustration, and the activity of one female crew member was studied during a race. Three types of data were collected: (a) audiovisual data recorded during the race; (b) verbalization data obtained in interviews conducted afterward; and (c) biomechanical data. The courses of experience of the two rowers during the race were reconstructed on the…

Supporting Identity Development in Talented Youth Athletes: Insights from Existential and Cultural Psychological Approaches

2020

The purpose of this article is to present existential and cultural psychology approaches to understanding athlete identity, and offer strategies for the development of well-rounded, reflexive and s...

In this review, state-of-the-art evidence on the relationship between cannabis use, traffic crash risks, and driving safety were analyzed. Systematic reviews, meta-analyses, and other relevant papers published within the last decade were systematically searched and synthesized. Findings show that meta-analyses and culpability studies consistently indicate a slightly but significantly increased risk of crashes after acute cannabis use. These risks vary across included study type, crash severity, and method of substance application and measurement. Some studies show a significant correlation between high THC blood concentrations and car crash risk. Most studies do not support this relationshi…

A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness

2018

The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…

Analyzing the metrics of the perceptual space in a new multistage physiological colour vision model

2009

In this work, the metric of a new multistage colour vision model, ATTD05, is assessed and a new colour difference formula is suggested. Firstly, the uniformity of the ATTD05 colour space was compared with that of CIECAM02 for some Munsell samples, because if the model yields a uniform perceptual space, we will be able to implement a colour difference formula as a Euclidian distance between two points. Secondly, we developed a new space based on the perceptual descriptors of the model: brightness, hue, colourfulness, and saturation. After that, we calculated the free parameters of the space that better fit the measured and experimental data of two datasets (small-magnitude and large-magnitud…

Evaluating the user experience of omnidirectional VR walking simulators

2020

Abstract Omnidirectional treadmills (ODTs) have been traditionally proposed as a promising solution for users’ navigation in large-scale virtual environments. These mechanical devices enable users to perform locomotive motion with 360-deg freedom, while keeping their position fixed in the physical world. However, most locomotion approaches based on omnidirectional treadmills have presented either high acquisition or maintenance costs, being the capabilities of the general public, or a limited reliability. In this paper, we present a comparative usability and acceptance study with real users evaluating the two most common approaches for the development of this type of Virtual Reality (VR) wa…

A reflective characterisation of occasional user

2017

This work revisits established user classifications and aims to characterise a historically unspecified user category, the Occasional User (OU). Three user categories, novice, intermediate and expert, have dominated the work of user interface (UI) designers, researchers and educators for decades. These categories were created to conceptualise user's needs, strategies and goals around the 80s. Since then, UI paradigm shifts, such as direct manipulation and touch, along with other advances in technology, gave new access to people with little computer knowledge. This fact produced a diversification of the existing user categories not observed in the literature review of traditional classificat…

A job-exposure matrix for research and surveillance of occupational health and safety in Spanish workers: MatEmESp

2013

BACKGROUND: In this study we describe a general-population job-exposure matrix (MatEmESp) for Spanish workers covering the period 1996-2005. METHODS: The Finnish job-exposure matrix (FINJEM) provided the default value estimates for occupational exposure to chemical, physical and biological agents. These estimates were adapted to Spanish working conditions by local experts. Spanish surveys were used to obtain exposure estimates for ergonomic and psychosocial risk factors. Employment and socio-demographic conditions for Spanish workers were obtained from the Spanish National Statistics Institute. RESULTS: MatEmESp provides a large amount of national and occupation-specific data on the major o…

Gender, Care, and the Normalization of Violence: Similarities between Occupational Violence and Intimate Partner Violence in Finland

2007

According to the statistics, violence against women is quite common in Finland, particularly in partner relationships and in care work. The present article looks at the similarities in the ways in which victims of occupational violence in care work and victims of intimate partner violence understand their experiences of violence. The commonalities among interpersonal relations are highlighted in order to offer new insights to the analysis of gender in research on occupational violence. Drawing on empirical data and research literature on the experiences of violence of Finnish women, this article suggests that minimization, naturalization and legitimization of the encountered violence is typ…
