Stress-related psychosocial factors at work, fatigue, and risky driving behavior in bus rapid transport (BRT) drivers
2016
Abstract Introduction There is consistent scientific evidence that professional drivers constitute an occupational group that is highly exposed to work related stressors. Furthermore, several recent studies associate work stress and fatigue with unsafe and counterproductive work behaviors. This study examines the association between stress-related work conditions of Bus Rapid Transport (BRT) drivers and risky driving behaviors; and examines whether fatigue is a mechanism that mediates the association between the two. Method A sample of 524 male Bus Rapid Transit (BRT) operators were drawn from four transport companies in Bogota, Colombia. The participants answered a survey which included an…
Expert Drivers' Prospective Thinking-Aloud to Enhance Automated Driving Technologies - Investigating Uncertainty and Anticipation in Traffic.
2020
Abstract Current automated driving technology cannot cope in numerous conditions that are basic daily driving situations for human drivers. Previous studies show that profound understanding of human drivers’ capability to interpret and anticipate traffic situations is required in order to provide similar capacities for automated driving technologies. There is currently not enough a priori understanding of these anticipatory capacities for safe driving applicable to any given driving situation. To enable the development of safer, more economical, and more comfortable automated driving experience, expert drivers’ anticipations and related uncertainties were studied on public roads. First, dri…
The long-term effects of rally driving on spinal pathology
2000
Abstract Objectives. To investigate the consequences of rally driving on lumbar degenerative changes. Background. Vehicular driving is suspected to accelerate disc degeneration through whole-body vibration, leading to back problems. However, in an earlier well-controlled study of lumbar MRI findings in monozygotic twins, significant effects of lifetime driving on disc degeneration were not demonstrated. Another study of machine operators found only long-term exposure to vibration on unsprung seats led to a reduction in disc height. Design. Case-control study comparing rally drivers with population sample. Methods. Eighteen top rally drivers and co-drivers, mean age 43 yrs (SD, 10), voluntee…
Digit ratio (2D:4D) is associated with traffic violations for male frequent car drivers
2009
Digit ratio (2D:4D) is a putative marker of prenatal hormone exposure. A lower digit ratio has been suggested as an index of higher testosterone relative to estrogen exposure during prenatal development. Digit ratio has been associated with a variety of psychological sex-dimorphic variables, including spatial orientation, aggression, or risk-taking behavior. The present study aimed to relate digit ratio to traffic violations for a male sample (N = 77) of frequent car drivers. Digit ratio was assessed via printout scans of the hand, and traffic offense behavior was assessed via self-reported penalty points as registered by the Central Register of Traffic Offenders in Germany. In addition, so…
NEUROMUSCULAR PERFORMANCE CHARACTERISTICS OF OPEN-WHEEL AND RALLY DRIVERS
2005
The purpose of the present study was to investigate neuromuscular performance characteristics in open-wheel and rally drivers using the cross-sectional study design. The subjects (N = 28) consisted of experienced international-level open-wheel drivers (n = 9), experienced international-level rally drivers (n = 9) and a physically active nondriving male control group (n = 10). In 3 separate test sessions, speed, muscle strength, and endurance tests were performed. The rally drivers had higher (p < 0.05) grip, shoulder flexion, and ankle plantar flexion strength, as compared to the control group. The open-wheel drivers showed higher strengths (p < 0.05) than the controls in neck forces, grip,…
Impaired regulation of emotion: Neural correlates of reappraisal and distraction in bipolar disorder and unaffected relatives
2015
Deficient emotion regulation has been proposed as a crucial pathological mechanism in bipolar disorder (BD). We therefore investigated emotion regulation impairments in BD, the related neural underpinnings and their etiological relevance for the disorder. Twenty-two euthymic patients with bipolar-I disorder and 17 unaffected first-degree relatives of BD-I patients, as well as two groups of healthy gender-, age- and education-matched controls (N=22/17, respectively) were included. Participants underwent functional magnetic resonance imaging while applying two different emotion regulation techniques, reappraisal and distraction, when presented with emotional images. BD patients and relatives …
Analysis of translocations that involve theNUP98 gene in patients with 11p15 chromosomal rearrangements
2004
The NUP98 gene has been reported to be fused with at least 15 partner genes in leukemias with 11p15 translocations. We report the results of screening of cases with cytogenetically documented rearrangements of 11p15 and the subsequent identification of involvement of NUP98 and its partner genes. We identified 49 samples from 46 hematology patients with 11p15 (including a few with 11p14) abnormalities, and using fluorescence in situ hybridization (FISH), we found that NUP98 was disrupted in 7 cases. With the use of gene-specific FISH probes, in 6 cases, we identified the partner genes, which were PRRX1 (PMX1; in 2 cases), HOXD13, RAP1GDS1, HOXC13, and TOP1. In the 3 cases for which RNA was a…
Associations between adverse childhood experiences and adversities later in life. Survey data from a high-risk Norwegian sample
2019
Abstract Background A history of childhood abuse and neglect (CAN) is associated with exposure to later negative life events. CAN at an early age, multiple cooccurring exposures (cumulative events), and a high severity and frequency of exposure have potential detrimental long-term effects. Objective The present study examines the relationship between the severity of CAN and the prevalence of school difficulties and hardship at school, adult adversity and mental health. Participants and Settings: Participants were recruited from in- and outpatient mental health or substance abuse treatment facilities, child protective services (CPS), and prisons (N = 809, age range = 13–66, mean age = 27.62,…
Sexual desire and sexual activity of men and women across their lifespans: results from a representative German community survey
2007
OBJECTIVES To present data on sexual desire and sexual activity from a representative survey of men and women covering the total age range of the adult German population, as previous studies have usually been based on samples selected for gender (either men or women) and age (ageing populations). SUBJECTS AND METHODS A representative sample of 2341 men and women aged 18-93 years were surveyed to determine frequency and intensity of sexual desire and sexual activity, and their social, individual and interpersonal characteristics. RESULTS Sexual desire declined with advancing age; overall, men reported more frequent and stronger sexual desire than women. However, there were important interact…
Childhood Victimization by Adults and Peers and Health-Risk Behaviors in Adulthood
2019
AbstractVictimization experienced in childhood has been linked with health-risk behaviors (HRBs) in adulthood. The purpose of this cross-sectional survey was to provide data regarding the HRBs using the ISPCAN Child Abuse Screening Tool Retrospective version (ICAST-R), Spanish version. This aimed to broaden existing knowledge by assessing both being victimized by adults and by peers in a Spanish general population of 348, aged 18–35. Age and timing of the reported victimization were also considered. Victimization: physical, psychological, sexual abuse by adults and/or peers showed a prevalence of 44.54%. Of these, 41.29% reported abuse by both. Children victimized by adults, regardless of t…
