Assessing the factor structure of the Behaviour of Young Novice Drivers Scale (BYNDS)
2020
Abstract The Behaviour of Young Novice Drivers Scale (BYNDS) is a self-report instrument to assess risky driving behaviours among youth population. Although previous studies have offered evidences of reliability and validity for the BYNDS scores, results are not conclusive as regards its factor structure. The aim of this research was to assess the factor structure of the BYNDS via Confirmatory Factor Analyses (CFA). The BYNDS was administered to a sample of 832 drivers aged from 18 to 25 years (Argentina = 270, Colombia = 350, and Mexico = 212). Six models were examined: three derived from previous literature, one emerged from an exploratory factor analysis, a unidimensional model, and a bi…
Consistency Between the Subjective Perception of Feeling Indisposed, the Decision to Drive and Driving Performance
2016
Drivers' health and fitness are essential issues in order to predict traffic crashes, taking into account that these characteristics are essential to perform this task correctly and safety. The purpose of this research was to analyze the frequency in which drivers who feel physically or emotionally unable to drive decide to perform this task, or not, under states of indisposition, as well as the perception of the effect that this indisposition had on driving. This cross-sectional study used a total sample of n=1200 (666 [56%] men and 534 [44%] women) Spanish drivers, who answered a questionnaire designed to collect data about their psychosocial characteristics, driving habits and perception…
Environmental problems and Geographic education. A case study: Learning about the climate and landscape in Ontinyent (Spain)
2021
AbstractCultural perceptions of the environment bring us back to elements and factors guided by “natural” cause-effect principles. It seems that academic education has had little effect on the manner and results of learning about changes in the local landscape, especially as regards rational explanations. There is considerable difficulty relating academic concepts about the climate to transformations in the environmental landscape. Teaching tasks are mediatized due to the use of rigorous and precise concepts which facilitate functional and satisfactory learning. This is the objective of the research this article aims to undertake, for which we have chosen the case of Ontinyent (Spain). This…
The Role of Perceived Relevance and Attention in Teachers’ Attitude and Intention to Use Educational Video Games
2017
Educational video games (EVGs) are becoming a trending topic in education as a new teaching methodology which can help teachers to increase students’ attention and engagement during the learning process. Nevertheless, despite an increasing academic interest in EVGs little research has been devoted to delve into teacher’s beliefs affecting their attitude towards EVGs and how these beliefs also affect their intention to use EVGs in their courses. Using Keller’s ARCS model as a theoretical framework, the role of perceived relevance and attention in teachers’ attitude and intention to use EVGs is analyzed. To do so a research model is tested using a sample of 312 Higher Education teachers via s…
Modélisation du comportement des agriculteurs face au risque dans un modèle de programmation mathématique positive (PMP) à grande échelle
2017
Agricultural production is characterized for being a risky business due to weather variability, market instability, plant diseases as well as climate change and political economy uncertainty. The modelling of risk at farm level is not new, however, the inclusion of risk in Positive Mathematical Programming (PMP) models is particularly challenging. Most of the few existing PMP-risk approaches have been conducted at farm-type level and for a very limited and specific sample of farms. This implies that the modelling of risk and uncertainty at individual farm level and in a large scale system is still a challenging task. The aim of this paper is to formulate, estimate and test a robust methodol…

Animal Welfare Attitudes (AWA) are defined as human attitudes towards the welfare of animals in different dimensions and settings. Demographic factors, such as age and gender are associated with AWA. The aim of this study was to assess gender differences among university students in a large convenience sample from twenty-two nations in AWA. A total of 7914 people participated in the study (5155 women, 2711 men, 48 diverse). Participants completed a questionnaire that collected demographic data, typical diet and responses to the Composite Respect for Animals Scale Short version (CRAS-S). In addition, we used a measure of gender empowerment from the Human Development Report. The largest varia…
Six Weeks of Confinement: Psychological Effects on a Sample of Children in Early Childhood and Primary Education
2020
Spain has been one of the countries most affected by the health crisis derived from COVID-19. Within this country, the city of Madrid has registered the highest number of infections and deaths. This circumstance led to the adoption of strict confinement measures for a period of 6 weeks. The objective of the present study was to investigate the psychological effects that this confinement has had on the psychological well-being of a sample of children from Madrid. A total of 167 families with children aged between 3 and 11 years participated in this study. The parents evaluated the children through the System of Evaluation of Children and Adolescents (SENA) scale in the month of February and …
Prevalence and Correlates of Physical activity in a sample of UK adults observing social distancing during the COVID-19 pandemic
2020
ObjectiveTo investigate the levels and correlates of physical activity during COVID-19 social distancing in a sample of the UK public.MethodsThis paper presents analyses of data from a cross-sectional study. Levels of physical activity during COVID-19 social distancing were self-reported. Participants also reported on sociodemographic and clinical data. The association between several factors and physical activity was studied using regression models.ResultsNine hundred and eleven adults were included (64.0% were women and 50.4% of the participants were aged 35–64 years). 75.0% of the participants met the physical activity guidelines during social distancing. Meeting these guidelines during …
Chiral Serum Pharmacokinetics of 4-Fluoroamphetamine after Controlled Oral Administration
2021
Abstract Over the last two decades, misuse of 4-fluoroamphetamine (4-FA) became an emerging issue in many European countries. Stimulating effects last for 4–6 hours and can impact psychomotor performance. The metabolism of amphetamine-type stimulants is stereoselective and quantification of (R)- and (S)-enantiomers has been suggested for assessing time of use. To date, no data on enantioselective pharmacokinetics is available for 4-FA in serum samples. An enantioselective liquid chromatography−tandem mass spectrometry (LC–MS-MS) method was developed using a chiral Phenomenex® Lux 3 μm AMP column. Validation of the method showed satisfactory selectivity, sensitivity, linearity (0.5–250 ng/mL…
