Pseudo-haptic Controls for Mid-air Finger-based Menu Interaction
2019
Virtual Reality (VR) is more accessible than ever these days. While topics like performance, motion sickness and presence are well investigated, basic topics as VR User Interfaces (UIs) for menu control are lagging far behind. A major issue is the absence of haptic feedback and naturalness, especially when considering mid-air finger-based interaction in VR, when "grabbable" controllers are not available. In this work, we present and compare the following two visual approaches to mid-air finger-based menu control in VR environments: a planar UI similar to common 2D desktop UIs, and a pseudo-haptic UI based on physical metaphors. The results show that the pseudo-haptic UI performs better in t…
The relationship between animal cruelty in children and adolescent and interpersonal violence: A systematic review
2019
Abstract The following study is a systematic review of the relationship between animal cruelty and interpersonal violence. The systematic literature review following PRISMA guidelines and combined with the application of inclusion and exclusion criteria, enabled us to locate 32 studies published between 1995 and July 2017. Overall, the results show that episodes of animal cruelty during childhood and adolescence tend to co-occur alongside other forms of violent and antisocial behaviors. Cruelty to animals was associated with bullying, behavioral problems, experiences of abuse (emotional, physical and sexual), and juvenile delinquency. Furthermore, recurrent animal cruelty during childhood a…

Driving under the influence of alcohol: frequency, reasons, perceived risk and punishment
2015
Background The aim of this study was to gain information useful to improve traffic safety, concerning the following aspects for DUI (Driving Under the Influence): frequency, reasons, perceived risk, drivers' knowledge of the related penalties, perceived likelihood of being punished, drivers’ perception of the harshness of punitive measures and drivers’ perception of the probability of behavioral change after punishment for DUI. Methods A sample of 1100 Spanish drivers, 678 men and 422 women aged from 14 to 65 years old, took part in a telephone survey using a questionnaire to gather sociodemographic and psychosocial information about drivers, as well as information on enforcement, clustered…
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…
Leadership and employees’ perceived safety behaviours in a nuclear power plant: A structural equation model
2011
Leadership is considered an essential element in guaranteeing the safe running of organizations. The purpose of the present study is to find out how leader behaviours influence employees' safety behaviours (perceived safety behaviours) in the nuclear field. In an attempt to answer this question, the authors of this research have considered the way this influence is exercised, taking into consideration some important factors like safety culture and safety climate. To achieve this, the empowerment leadership model, based on a behavioural approach to leadership, was used. The sample was made up of 566 employees from a Spanish nuclear power plant. The results indicated that when safety culture …

The occupation of dental assistants (DAs) involves many health risks of the musculoskeletal system due to static and prolonged work, which can lead to musculoskeletal disorders (MSDs). The aim of the study was to investigate the prevalence of MSDs in DAs in Germany. Methods: For this purpose, an online questionnaire analyzed 406 (401 female participants and 5 male participants, 401w/5m) DAs. It was based on the Nordic Questionnaire (lifetime, 12-month, and seven-day MSDs’ prevalence separated into neck, shoulder, elbow, wrist, upper back, lower back, hip, knee, and ankle), and occupational and sociodemographic questions as well as questions about specific medical conditions. Results: 98.5% …
Profiling Safety Behaviors: Exploration of the Sociocognitive Variables that Best Discriminate Between Different Behavioral Patterns
2012
This study combines contributions from both safety climate literature and prominent social influence theories. It was developed to identify the combination of sociocognitive variables that differentiate between different profiles of safety behaviors. This empirical approach has hardly been explored in the literature on behavioral aspects related to safety. The research setting for this study was a transportation company (N= 356). The results of discriminant analysis showed that different combinations of dispositional and situational influences may lead to diverse profiles of compliance and proactive safety behaviors. Perceived behavioral control was revealed to be the variable that best dif…
Mobbing in Schools and Hospitals in Uruguay: Prevalence and Relation to Loss of Status.
2017
In the present study in secondary schools and hospitals in Uruguay ( N = 187), we examined the relationship between feeling the victim of mobbing and a perceived loss of status. Nearly all forms of mobbing were more prevalent among hospital employees than among school employees. Among hospital employees, 40.4%, and among school employees, 23.9% reported being the victim of mobbing at least once a week. Being the victim of mobbing was, in both hospitals and schools, more prevalent among older employees, and in hospitals, among employees who were more highly educated and who had been employed for a longer time. Men and women did not differ in reporting that one was a victim of mobbing, but m…
When age means safety: Data to assess trends and differences on rule knowledge, risk perception, aberrant and positive road behaviors, and traffic cr…
2019
This data article examines the association between age, knowledge of traffic rules, risk perception, risky and positive behaviors on the road and traffic safety outcomes of cyclists. The data was collected using a structured self-administrable and online-based questionnaire, applied to a full sample of 1064 cyclists. The data contains 4 parts: descriptive statistics; graphical trends for each study variable according to age; Post-Hoc (Tukey-HSD) comparisons between cyclists classified in the different age groups; and, finally, the dataset for further explorations in this regard. For further information, it is convenient to read the full article entitled "Explaining Self-Reported Traffic Cra…
