Parental socialization, vagal regulation, and preschoolers' anxious difficulties: direct mothers and moderated fathers.

Abstract: Parental supportiveness and protective overcontrol and preschoolers' parasympathetic regulation were examined as predictors of temperamental inhibition, social wariness, and internalizing problems. Lower baseline vagal tone and weaker vagal suppression were expected to mark poorer dispositional self-regulatory capacity, leaving children more susceptible to the influence of parental socialization. Less supportive mothers had preschoolers with more internalizing problems. One interaction between baseline vagal tone and maternal protective overcontrol, predicting social wariness, conformed to the moderation hypothesis. Conversely, vagal suppression moderated several links between paternal socialization and children's anxious difficulties in the expected pattern. There were more links between mothers' self-reported parenting and child outcomes than were noted for direct observations of maternal behavior, whereas the opposite tended to be true for fathers.

Assessing the development of automaticity in second language word recognition.

Abstract: This study investigated the development of automaticity in second language word recognition. In an earlier study (Segalowitz & Segalowitz, 1993) we demonstrated that a reduction in the coefficient of variation of lexical decision reaction time (CV RT ) - the standard deviation of reaction time divided by mean reaction time (RT) - reflects a restructuring of underlying cognitive processing mechanisms in the direction of increased automaticity and not a simple speed-up of those mechanisms. In the current study, English speakers studying French performed multiple lexical decision tasks. Differences in CV RT were compared cross-sectionally and longitudinally. As in the earlier study, crosssectional analyses showed that CV RT correlated positively with RT for initially fast, but not initially slow, responders. CV RT also correlated positively with RT in longitudinal analyses. These results confirm that, with extended learning experience, the cognitive components underlying word recognition are restructured (automatized) and not simply speeded-up.

Evaluating the effectiveness of road mitigation measures

Abstract: The last 20 years have seen a dramatic increase in efforts to mitigate the negative effects of roads and traffic on wildlife, including fencing to prevent wildlife-vehicle collisions and wildlife crossing structures to facilitate landscape connectivity. While not necessarily explicitly articulated, the fundamental drivers behind road mitigation are human safety, animal welfare, and/or wildlife conservation. Concomitant with the increased effort to mitigate has been a focus on evaluating road mitigation. So far, research has mainly focussed on assessing the use of wildlife crossing structures, demonstrating that a broad range of species use them. However, this research has done little to address the question of the effectiveness of crossing structures, because use of a wildlife crossing structure does not necessarily equate to its effectiveness. The paucity of studies directly examining the effectiveness of crossing structures is exacerbated by the fact that such studies are often poorly designed, which limits the level of inference that can be made. Without well performed evaluations of the effectiveness of road mitigation measures, we may endanger the viability of wildlife populations and inefficiently use financial resources by installing structures that are not as effective as we think they are. In this paper we outline the essential elements of a good experimental design for such assessments and prioritize the parameters to be measured. The framework we propose will facilitate collaboration between road agencies and scientists to undertake research programs that fully evaluate effectiveness of road mitigation measures. We discuss the added value of road mitigation evaluations for policy makers and transportation agencies and provide recommendations on how to incorporate such evaluations in road planning practices.

A DEMATEL based approach for investigating barriers in green supply chain management in Canadian manufacturing firms

Abstract: Green supply chain management (GSCM) involves consideration of environmental impacts of all the processes involved in a typical supply chain to minimise their negative consequences. In this paper, ...

Cognitive functioning of older people in relation to social and personality variables.

Abstract: Age differences in performance on memory measures and in subjective ratings of memory adequacy were examined in the context of 12 social, personality, adjustment, and lifestyle measures. Participants were 285 men and women, aged 65 to 93, of middle- and working-class backgrounds. A series of multivariate and univariate analyses revealed that a large proportion of the age differences and virtually all of the social-class differences on memory measures could be accounted for by contextual variables, with education, intellectual activity, extroversion, neuroticism, and lie scores (on the Eysenck Personality Inventory) all accounting for more of the variance in memory performance than did age. Self-rated memory adequacy was not correlated with performance, and although the expected finding of lower ratings by older participants was obtained with the working-class group, the opposite was true for the middle-class group. Implications of these results for understanding age differences in memory are discussed.
