Conditions for speeding behaviour: A comparison of car drivers and powered two wheeled riders

Against a UK background of decreases in collisions involving car drivers, motorcycle collisions are on the increase. To throw light on this process, this paper explores differences between motorcyclists and car drivers in the conditions for speeding behaviour. Some predictions derived from the model of Task-difficulty Homeostasis (TDH) were tested using self-report data from samples of older (>35 years), male car drivers (n = 269) and motorcyclists (n = 102). As predicted, riders were more likely to speed on rural roads and less likely to speed on urban roads, and, riders were much more likely to speed in daytime than at night.Riding a motorcycle offers opportunities for expressive use of the vehicle and riders are more likely to say they really enjoy riding fast. However amongst older riders this behaviour appears to be largely confined to daytime riding on rural roads. Compared with cars, motorcycles provide more of an opportunity to manoeuvre around obstacles in controlling task demand, rather than using speed as the primary controlling variable. Although this provides more options for the rider, it carries with it vulnerability to loss of control from variation in road surface adhesion and maintaining too high a speed.     

Physical and Relational Aggression in Early Adolescence: Associations with Narcissism,Temperament, and Social Goals

This study examined adolescent narcissism, temperament (frustration and affiliation), and social goals in association with peer‐reported physical and relational aggression (N = 384; 12–14 years). Narcissism was positively associated with dominance goals and negatively with closeness goals for peer interaction. Moreover, narcissism was positively associated with physical aggression via dominance goals for boys, and with relational aggression via dominance goals for both genders. Temperamental frustration and affiliation were both positively associated with relational aggression, but also interacted in their associations with this variable; affiliation was positively associated with relational aggression only at high levels of frustration. Supporting and extending existing research, the present findings suggest that adolescent personality and social goals are meaningfully associated with physical and relational aggression in the peer context.     

The Art of Being Human: A Project for General Philosophy of Science

Throughout the medieval and modern periods, in various sacred and secular guises, the unification of all forms of knowledge under the rubric of ??science?? has been taken as the prerogative of humanity as a species. However, as our sense of species privilege has been called increasingly into question, so too has the very salience of ??humanity?? and ??science?? as general categories, let alone ones that might bear some essential relationship to each other. After showing how the ascendant Stanford School in the philosophy of science has contributed to this joint demystification of ??humanity?? and ??science??, I proceed on a more positive note to a conceptual framework for making sense of science as the art of being human. My understanding of ??science?? is indebted to the red thread that runs from Christian theology through the Scientific Revolution and Enlightenment to the Humboldtian revival of the university as the site for the synthesis of knowledge as the culmination of self-development. Especially salient to this idea is science??s epistemic capacity to manage modality (i.e. to determine the conditions under which possibilities can be actualised) and its political capacity to organize humanity into projects of universal concern. However, the challenge facing such an ideal in the twentyfirst century is that the predicate ??human?? may be projected in three quite distinct ways, governed by what I call ??ecological??, ??biomedical?? and ??cybernetic?? interests. Which one of these future humanities would claim today??s humans as proper ancestors and could these futures co-habit the same world thus become two important questions that general philosophy of science will need to address in the coming years.
