Are Latin American cycling commuters 'at risk'? A comparative study on cycling patterns, behaviors, and crashes with non-commuter cyclists

2020

Abstract Introduction As part of the transformation of urban transportation dynamics, commuter cycling has acquired a high relevance as an alternative mode of transport in different countries, and Latin America seems to be one of the main focus of this worldwide “revolution”. However, the high rates of crashes and injuries suffered by commuters have become a relevant issue in the field of road safety, especially in emerging regions with low cycling tradition, where social and infrastructural gaps may endanger the cyclists’ safety. Objectives This study had two objectives. First, to compare key safe cycling-related variables between cycling commuters and non-commuters; and second, to differe…

Generalization of mental health across life sectors

1975

.— Questionnaire data on mental health in three life areas (work, family, and leisure) were analysed by ANOVA together with estimation of the magnitudes of different effects. The Ss were 60 employed women with varied marital status. About 55% of mental health variation was explained by the generalization model and 4% by the person by life area interaction. It was suggested that analysis of variance components is useful in comparing corresponding effects in different groups of subjects. Some limitations of cross-sectional research strategy were discussed, stressing the need for other strategies in research on the relation between mental health in different life areas.

The influence of organizational factors on road transport safety

2018

Road transport safety is a major concern across Europe due to the human and socio-economic costs associated with work-related traffic accidents. Traditional approaches have adopted regulatory and technical measures to prevent road accidents leaving aside the organizational factors that might contribute to road transport safety. However, contemporary sociotechnical systems theory acknowledges the need to take into account organizational factors. This study adopts a sociotechnical approach and it examines the relationship between a number of organizational factors (organizational learning and training) and road traffic accidents in the organizations under study. Our sample was composed of 107…

The university campus environment as a protective factor for intimate partner violence against women: An exploratory study

2017

Some neighborhood characteristics linked to social disorganization theory have been related to intimate partner violence against women (IPVAW). The study of other neighborhood-level factors that may influence IPVAW risk, however, has received less attention. The aim of this study is to analyze the influence of university campuses on IPVAW risk. To conduct the study, IPVAW cases from 2011 to 2013 in the city of Valencia, Spain, were geocoded (n = 1,623). Census block groups were used as the neighborhood analysis unit. Distance between each census block group and the nearest university campus was measured. A Bayesian spatial model adjusted for census block group-level characteristics was perf…

Prevalencia de la violencia de parejas en España: estudio transversal a través de cuestionario en la atención primaria

2017

Objectives: (1) To analyze the prevalence of Intimate Partner Violence by types. (2) To examine the relationship between sociodemographic characteristics and Intimate Partner Violence. Design: Cross-sectional study using a self-administered questionnaire. Setting: Primary Healthcare centers in Spain. Participants: 10,322 women (18–70 years) attending Primary Healthcare centers. Main measurements: A compound index was calculated based on frequency, types, and duration of Intimate Partner Violence. Multivariable adjusted logistic regression models were used to identify the sociodemographic factors, which were independently associated with each Intimate Partner Violence category. Results: The …

Ski Boots Do Not Impair Standing Balance by Restricting Ankle-Joint Mobility.

2018

Objective: This study was undertaken in order to provide new insight into sensorimotor control of posture when wearing high-shaft (HS) boots as ski boots. Background: Previous studies into the effects of HS boots on postural control have produced controversial results. Some studies reported postural control impairments with ski boots in bipedal postural tasks due to ankle movement restrictions without quantifying the actual restrictive effect of these boots and specifying the adaptations of the postural control system. Method: Eighteen young healthy subjects took part in the experiment. Bilateral postural control was assessed on stable and unstable surfaces, while standing barefoot or weari…

Evaluating human body area factors from digital images: A measurement tool for a better evaluation of the ergonomics of working places

2006

The evaluation of comfort conditions of people in confined environments requires a knowledge of the human body's radiation data. This is essentially represented by the projected area of the body in a given direction. From this factor, other important parameters can be computed, such as projected area factors and angle factors. Presently, these parameters are evaluated using graphs deriving from a pioneering field study carried out by P.O. Fanger for which a piece of apparatus using mirrors and weight operations on film negatives is used. Obviously, these graphs, apart from referring to a limited number of subjects, also involve some reading errors. With the aim of enlarging the number of ex…

Sex differences in genetic and environmental effects on aggression

2003

The aim of the present study was to investigate the genetic and environmental factors influencing teacher and parental rated aggression in boys and girls, asking whether the magnitude of these effects is similar across rater and sex. The study is part of an ongoing nationwide twin-family study of behavioral development and health habits carried out in Finland. The sample consisted of 1651 twin pairs (264 monozygotic male, 300 monozygotic female, 292 dizygotic male, 278 dizygotic female, and 517 dizygotic opposite-sex twin pairs), representing subsets of five 11- to 12-year-old twin cohorts (b. 1983-1987). The data were collected using the teacher and parental rating forms of the Multidimens…

Offensive and defensive aggression in humans: A longitudinal perspective

1987

Offensive and defensive aggression were distinguished on the basis of associated events. Behavior delivering noxious stimuli was defined as defensive when it was a response a threatening situation and as offensive when it was an unprovoked act. The existence of a general aggression factor was implied by the finding that initiators of aggression also readily defend themselves if attacked. The use of a peer nomination and teacher rating variable for offensive aggression, “Attacks without reason, teases others, naughty things”; and another for defensive aggression, “Defends him/herself if teased, but does not tease or attack others without reason,” yielded differential results. Offensive aggre…
