Using an integrated simulation environment for the risk based design of advanced driver assistance systems

When designing new Advanced Driver Assistance Systems (ADAS), the existing guidelines like the RESPONSE 3 Code of Practice imply intense testing of the system prior series production. Within the EU-FP7-Project ISi-PADAS a new methodology of risk based design has been established which includes an integrated simulation platform. This integration enables intense testing of new prototypes in an accelerated way and therefore enhances the design process while directly combining the simulation results with a risk matrix.This paper describes the new methodology while focussing on the software framework and the procedure of risk assessment in detail. It shows the general approach as well as the appropriate steps taken for an ADAS prototype developed in the context of ISi-PADAS.     

Association of preterm birth and intrauterine growth restriction with childhood motor development: Brisa cohort,Brazil

The present study investigated the association between preterm birth PT conditions, intrauterine growth restriction IUGR and the combination of both PT-IUGR with infant motor development. A cohort with 1006 children was monitored during prenatal, at birth, and two years of age. Bayley-III screening was used to evaluate of fine and gross motor skills. The data did not indicate an increased risk for motor delays in the PT or IUGR, composed mainly by mild cases. However, the combination of the conditions PT-IUGR increased the risk of delays in motor, which emphasizes the importance of monitoring the motor development of the group.     

Gaining perspectives: A scoping review of research assessing depressive symptoms in athletes

The aim of this review was to 1) describe methodological characteristics of the research that has assessed depressive symptoms in athletes, and 2) to map the variables that have been tested in relation to these symptoms. A review framework proposed by Arksey and O’Malley (2005) was utilized, and of 6983 records screened, 157 studies were included. Most studies were cross-sectional, with samples including current male and female athletes from multiple sports and levels. Non-athlete comparison groups frequently consisted of student samples. Twenty-eight different depression scales were utilized, of which CES-D, BDI, BDI-II, and the PHQ-9 were most common. The most commonly tested variables in relation to depressive symptoms were identified as proximal (micro- and meso-level) sport-specific (e.g. type of sport) (36.4%) and generic (e.g. sex) (31.5%) factors. Within-individual vulnerabilities (e.g. neurocognitive performance) accounted for 17.2%, while comorbid disorders accounted for 9.3%, and macro-level variables (e.g. ethnicity) for 5% of all observations. Longitudinal studies within specific sports are needed to understand the relative influence of sport-specific and generic factors on depressive symptoms in athletes. Few studies explored sociocultural or macro-level factors, and research concerning within-individual vulnerability is fragmented and needs to be further explored to inform individual-level support and prevention initiatives.     

One-year test–retest reliability of the Maryland Resource for the Behavioral Utilization of the Reinforcement of Negative Stimuli (MRBURNS)

The Maryland Resource for the Behavioral Utilization of the Reinforcement of Negative Stimuli (MRBURNS) is a novel behavioral task designed to measure individual differences in negative reinforcement-based risk taking propensity. Performance on the MRBURNS has been linked with alcohol-related problems and negative reinforcement-based drinking motives, as well as symptoms of anxiety and depression; however, it is unclear if performance on the task represents a stable measure of negative reinforcement-based risk taking over time. As such, the current study aimed to examine the test–retest reliability of the MRBURNS over a period of one year. Results indicate that the correlation between year 1 and year 2 risk behavior (average number of pumps) on the MRBURNS was .43 across all trials. With the one year test–retest reliability of the MRBURNS established, the MRBURNS may be a useful approach to measuring the relative contribution of negative reinforcement-based risk taking in the development of risky behaviors over time, and may be used to monitor the effects of novel interventions that aim to reduce negative reinforcement based risk taking in the real world.
