Survey of New Zealand truck driver fatigue and fitness for duty

This paper presents recent research into compliance with current driving hours regulations, the effectiveness of using driving hours to predict fatigue, and alternative compliance and enforcement options. The paper describes results of a major survey of truck driver fatigue in New Zealand, a review of international compliance and enforcement procedures, and research focussing on the social forces and influences that affect truck drivers. The survey of truck drivers was based on interviews and performance tests collected from 600 truck drivers at depots, wharves, markets, and other locations throughout the North Island of New Zealand. The interviews included: questions on driver demographic and work/rest patterns, drivers' attitudes towards fatigue, propensity towards daytime sleepiness, and a self-assessment of the driver's momentary level of fatigue. In addition, a simulator-based performance test of driving was undertaken. The performance test included a combination of a standard driving task, a dual-axis sub-critical tracking task (maintaining speed and steering in a controlled but unstable environment, a virtual roadway affected by the appearance of random wind gusts requiring steering correction), and a tertiary or side-task requiring driver monitoring and periodic responses. The initial results from the first 100 drivers have found a sizable number of drivers exceeding the allowable driving hours, high levels of fatigue and sleepiness, and interesting differences between line-haul and local delivery drivers. A related research project into the social processes and relationships that affect truck drivers has resulted in a good understanding of the social conditions that influence cultural change and the actions of truck drivers and fleet managers. In this paper we will have particular regard to these processes in the construction of ideas concerning safety. This includes an understanding of the role of major stakeholders, such as freight forwarders and the enforcement agencies with respect to drivers and their conditions, actions and understanding of the road transport industry. This knowledge coupled with the survey results and an understanding of compliance and enforcement alternatives will be used to explore potential fatigue management options.     

Parents’ perceptions of the Family Climate for Road Safety: Associations with parents’ self-efficacy and attitudes toward accompanied driving,and teens’ driving styles

In order to better understand parental influence on teen driving, a series of three studies were conducted among parents of young drivers to examine the association between their scores on the Family Climate for Road Safety Scale (FCRSS; Taubman – Ben-Ari & Katz – Ben-Ami, 2013) and three relevant factors: parental self-efficacy (Study 1, n = 101); parents’ attitudes toward accompanied driving (Study 2, n = 100); and teen’s driving styles (Study 3, n = 235 parents–young drivers pairs). The findings of Study 1 revealed significant associations between parents’ scores on the positive FCRSS dimensions and their self-reported parental competence. In addition, parents’ lack of commitment to safe driving was related to lower parental self-efficacy. Study 2 indicated significant associations between parents’ scores on the positive FCRSS dimensions and the positive attitude of relatedness during the accompanied driving phase. Negative associations were found between these FCRSS dimensions and negative perceptions of the accompanied driving phase (i.e., tension, disapproval, and avoidance). The findings of Study 3 showed significant associations between parents’ scores on the positive FCRSS dimensions and their offspring’s careful driving style, as well as negative associations between these dimensions and offspring’s endorsement of the reckless, angry, and anxious driving styles. Taken together, the results indicate the importance of the family climate as part of a global understanding of the dynamic surrounding youngsters’ driving. Furthermore, they show that the particular driving-related family climate is associated not only with parents’ self-perceptions and conduct in the early stages of their children’s driving (the accompanied driving phase of a GDL), but also impacts the way teenagers ultimately choose to drive, when they are on their own. Implications for interventions are discussed.     

Safety behaviour does not necessarily interfere with exposure therapy

There has been much recent controversy regarding whether or not the use of safety and other neutralizing behaviour interferes with exposure-based therapy. The aim of this study was to examine the role of safety behaviour in the treatment of specific phobia. Sixty-two snake-fearful participants were randomized to a 45-min exposure session with or without the use of safety gear, such as gloves and goggles. During the treatment, participants in the safety behaviour group were able to achieve a significantly closer initial distance of approach to the snake compared to controls. When tested post-treatment without any safety gear, both groups demonstrated comparable treatment gains involving significant reductions in fearful cognitions and subjective anxiety, as well as significant improvements in distance of approach. Results suggest that reliance on safety behaviour during exposure therapy for anxiety disorders may not interfere with treatment outcome.

Safety,Risk Acceptability,and Morality

The primary aim of this article is to develop and defend a conceptual analysis of safety. The article begins by considering two previous analyses of safety in terms of risk acceptability. It is argued that these analyses fail because the notion of risk acceptability is more subjective than safety, as risk acceptability takes into account potential benefits in a way that safety does not. A distinction is then made between two different kinds of safety-safety qua cause and safety qua recipient-and both are defined in terms of the probability of a loss of value, though the relationship between safety and the probability of loss varies in each case. It is then shown that although this analysis is less subjective than the previously considered analyses, subjectivity can still enter into judgments of safety via the notions of probability and value. In the final section of this article, it is argued that the difference between safety and risk acceptability is important because it corresponds in significant ways to the difference between consequentialist and deontological moral viewpoints.     

Untangling the Debate: The Ethics of Human Enhancement

Human enhancement, in which nanotechnology is expected to play a major role, continues to be a highly contentious ethical debate, with experts on both sides calling it the single most important issue facing science and society in this brave, new century. This paper is a broad introduction to the symposium herein that explores a range of perspectives related to that debate. We will discuss what human enhancement is and its apparent contrast to therapy; and we will begin to tease apart the myriad intertwined issues that arise in the debate: (1) freedom & autonomy, (2) health & safety, (3) fairness & equity, (4) societal disruption, and (5) human dignity.
