Understanding risky behaviours in nuclear facilities: The impact of role stressors
2018
Abstract Risky behaviours have received little attention in the safety literature in recent years, compared to safety behaviours such as safety compliance or safety participation. However, it is important to focus on risky behaviours and their predictors in order to prevent accidents. The aim of this study is to explore the impact of role stressors (role ambiguity and role overload) on risky behaviours, and the mediating role of dissatisfaction (both job and safety dissatisfaction). The sample consists of 566 employees from two nuclear power plants in Spain. Structural equation modelling is used to determine the effects of role ambiguity and role overload on risky behaviours. Role stressors…
A virtual reality system for the treatment of stress-related disorders: A preliminary analysis of efficacy compared to a standard cognitive behaviora…
2011
This paper presents preliminary efficacy data in a controlled study of the use of a virtual reality (VR) system for treating stress-related disorders (Post-Traumatic Stress Disorder, or PTSD; Pathological Grief, or PG; and Adjustment Disorders, or AD). ''EMMA's World'' is a VR application in which patients can explore negative experiences to the degree required for their specific therapeutic needs. To accomplish therapeutic goals, a series of virtual elements is customized to be meaningful to the user; the elements contain the fundamental emotional components that the person must confront. Thirty-nine participants diagnosed with PTSD (N=10), PG (N=16), and AD (N=13) were randomly assigned t…
Relations Between Suicidal Ideation, Depression, and Emotional Autonomy from Parents in Adolescence
2010
We examined the relations between depression, emotional autonomy quality-related constructs of separation and detachment, and suicidal ideation, focusing on the unique and common contribution that depression, separation and detachment made to suicidal ideation. We also examined gender differences. 403 adolescents, 196 boys and 207 girls, completed self-report measures of depression, separation and detachment, and suicidal ideation. The data showed a significant relation between depression and suicidal ideation both for boys and girls, and between detachment and suicidal ideation only for boys. Results for boys supported an additive model such that depression and detachment each contributed …
Male Police Officers’ Law Enforcement Preferences In Cases of Intimate Partner Violence Versus Non-Intimate Interpersonal Violence
2014
This article explores male police officers’ law enforcement preferences across different scenarios of interpersonal violence, involving intimate (partner violence against women) and non-intimate relationships (between- and within-gender). The influence of police officers’ sexist attitudes and empathy on their law enforcement preferences was also analyzed within and across these scenarios. The sample consisted of 308 male police officers. Results showed that police officers prefer a stronger and unconditional law enforcement approach in cases of violence against women, both in intimate and non-intimate relationships. Benevolent sexism was linked to a preference for a more conditional law en…
Ambivalent sexism, empathy and law enforcement attitudes towards partner violence against women among male police officers
2013
Police attitudes towards partner violence against women (PVAW) can play an important role in their evaluation and responses to this type of violence. The present study aims to examine ambivalent sexism and empathy as determinants of male police officers' law enforcement attitudes towards PVAW. The study sample was composed by 404 male police officers. Results suggested that male police officers scoring low in benevolent sexism expressed a general preference for unconditional law enforcement (i.e. regardless of the victim's willingness to press charges against the offender), whereas those scoring high in benevolent sexism expressed a preference for conditional law enforcement (i.e. depending…
Trait driving anger and driving styles among Colombian professional drivers
2019
Abstract This study analyzes the association between trait driving anger and driving styles in a sample of Colombian professional drivers. Additionally, the internal and external validity of the Deffenbacher's Driving Anger Scale (DAS-14) was examined in the study population. The DAS-14 and the Spanish Version of the Multidimensional Driving Style Inventory (S-MDSI) were administered to 492 urban bus and taxi operators. Average trait driving anger scores in the study population were similar to those reported in previous validation studies from Spain, Argentina, China, and Malaysia. After deleting three cross-loaded items, confirmatory factor analyses revealed a three-dimensional latent stru…
"Bad romance": Links between psychological and physical aggression and relationship functioning in adolescent couples
2015
Contains fulltext : 150442.pdf (Publisher’s version ) (Open Access) Assortative mating is an important issue in explaining antisocial, aggressive behavior. It is yet unclear, whether the similarity paradigm fully explains frequent displays of aggression in adolescents' romantic relationships. In a sample of 194 romantic partner dyads, differences between female and male partners' reports of aggression (psychological and physical) and different measures of relationship functioning (e.g., jealousy, conflicts, and the affiliative and romantic quality of the relationship) were assessed. A hierarchical cluster analysis identified five distinct subgroups of dyads based on male and female reports …
Effect of footwear on plantar flexor fine-wire electromyography activity in walking
2019
Compared to barefoot walking, walking in footwear seems to alter plantar flexor electromyography (EMG) activity, vertical and horizontal ground reaction forces (Sacco, Akashi, & Hennig, 2010), ankle kinematics and the time of peak activity (Sacco et al., 2010). However, study results are inconsistent regarding the magnitude and direction of these changes. Magnetic resonance imaging showed high inter-individual variability in muscle metabolic activity during walking, suggesting individual-specific activation patterns (Kolk et al., 2015). Additionally, little is known about the role of toe flexors such as flexor hallucis longus (FHL) in walking.
Replication and extension of framing effects to compliance with health behaviors during pandemics
2021
Outbreaks of infectious diseases represent a significant challenge for health authorities around the world Public cooperation and compliance with health recommendations constitute critical steps to stop the spread of such diseases But how should these recommendations be framed to achieve the most desirable outcomes? Across two experiments, we show that the classic Asian Disease Problem (Tversy and Kahneman, 1981) is replicable, regardless of disease type (real vs hypothetical) Thus, people are less (vs more) willing to take risks when information is positively (negatively) framed, irrespective of disease type, although they are generally more risk-averse in real pandemics Furthermore, peopl…
Alcohol use, aquatic injury, and unintentional drowning: A systematic literature review
2018
Issues: Drowning is a global public health issue, and there is a strong association between alcohol and risk of drowning. No previous systematic review known to date has identified factors associated with alcohol use and engagement in aquatic activities resulting in injury or drowning (fatal and non-fatal). Approach: Literature published from inception until 31 January 2017 was reviewed. Included articles were divided into three categories: (i) prevalence and/or risk factors for alcohol-related fatal and non-fatal drowning and aquatic injury, (ii) understanding alcohol use and aquatic activities, and (iii) prevention strategies. Methodological quality of studies was assessed using National …
