‘Full‐time is a Given Here’: Part‐time Versus Full‐time Job Quality*

This study explores full‐time workers' understanding of and assumptions about part‐time work against six job quality components identified in recent literature. Forty interviews were conducted with employees in a public sector agency in Australia, a study context where part‐time work is ostensibly ‘good quality’ and is typically long term, voluntary, involving secure contracts (i.e. permanent rather than casual) and having predictable hours distributed evenly over the week and year. Despite strong collective bargaining arrangements as well as substantial legal and industrial obligations, the findings revealed some serious concerns for part‐time job quality. These concerns included reduced responsibilities and lesser access to high status roles and projects, a lack of access to promotion opportunities, increased work intensity and poor workplace support. The highly gendered, part‐time labour market also means that it is women who disproportionately experience this disadvantage. To foster equity, greater attention needs to focus on monitoring and enhancing job quality, regardless of hours worked.     

‘Ethnicity’: The Irish in Scotland‐football,politics and identity

One of the central arguments of this paper is that football in Scotland has acquired characteristics which make it a nationalistic, political and cultural repository. An examination of football allows us to examine characteristics of identity in Scotland otherwise unclear. These identities have their origins in the post‐Reformation period in Scotland, Irish immigration into Scotland and Scotland/Britain's historically contentious relationship with Ireland. This paper examines some of the mainfeatures of these identities.     

Inference for nonconjugate Bayesian Models using the Gibbs sampler

A Bayesian approach to modeling a rich class of nonconjugate problems is presented. An adaptive Monte Carlo integration technique known as the Gibbs sampler is proposed as a mechanism for implementing a conceptually and computationally simple solution in such a framework. The result is a general strategy for obtaining marginal posterior densities under changing specification of the model error densities and related prior densities. We illustrate the approach in a nonlinear regression setting, comparing the merits of three candidate error distributions.     

Monitoring proteins in intact cells

In the past decade, tremendous progress has been made in understanding the molecular mechanisms that underlie many neurodegenerative disorders, and common aspects of the pathological processes that lead to neuronal cell death have emerged. Nearly all of these advances have come from genetic, molecular, and biochemical studies that point to alterations in protein folding or protein-protein interactions as the fundamental mechanism behind these disorders. New microscopy/imaging technologies for detecting protein-protein interactions are now poised to contribute to progress in this field. Here we describe a novel technique based on fluorescence resonance energy transfer, called fluorescence lifetime imaging microscopy (FLIM), which allows monitoring of protein conformation and protein-protein interactions in intact cells. For example, using FLIM, we have studied the interaction of two proteins related to Alzheimer's disease: amyloid precursor protein (APP) and presenilin (PS-1). By measuring the lifetime of a donor fluorophore linked to PS-1, we show, with high subcellular resolution, localization of the PS-1-APP interaction within neurons. This approach may have widespread applicability in studies of neurodegenerative disease mechanisms.     

Differences in university students’ motivation between a required and an elective physical activity education policy

Objective: The aim of this study was to examine differences in students’ physical activity motivation, competence, and weekly exercise metabolic equivalent units (METs) between universities with different physical activity education (PAE) policy arrangements (ie, a required PAE vs. an elective PAE). Participants: Participants (N?=?953) were purposefully recruited from two universities with different PAE policies 1 week before the start of fall term 2015. Methods: Participants completed questionnaires assessing their physical activity motivation, competence, and weekly exercise METs. Results: The results of this study suggest that having a required PAE policy allows for more students with lower self-determined forms of motivation (ie, amotivation) to be reached in comparison to the elective PAE policy. Conclusions: This finding highlights that a primary value of having a required PAE policy is its ability to reach less motivated students.     

Technology‐Based Communication and the Development of Interpersonal Competencies Within Adolescent Romantic Relationships: A Preliminary Investigation

This study investigated longitudinal associations between adolescents’ technology‐based communication and the development of interpersonal competencies within romantic relationships. A school‐based sample of 487 adolescents (58% girls; M_age = 14.1) participated at two time points, one year apart. Participants reported (1) proportions of daily communication with romantic partners via traditional modes (in person, on the phone) versus technological modes (text messaging, social networking sites) and (2) competence in the romantic relationship skill domains of negative assertion and conflict management. Results of cross‐lagged panel models indicated that adolescents who engaged in greater proportions of technology‐based communication with romantic partners reported lower levels of interpersonal competencies one year later, but not vice versa; associations were particularly strong for boys.     

Developmental Differences in Infants' Attention to Social and Nonsocial Threats

Research has demonstrated that humans detect threatening stimuli more rapidly than nonthreatening stimuli. Although the literature presumes that biases for threat should be normative, present early in development, evident across multiple forms of threat, and stable across individuals, developmental work in this area is limited. Here, we examine the developmental differences in infants' (4‐ to 24‐month‐olds) attention to social (angry faces) and nonsocial (snakes) threats using a new age‐appropriate dot‐probe task. In Experiment 1, infants' first fixations were more often to snakes than to frogs, and they were faster to fixate probes that appeared in place of snakes vs. frogs. There were no significant age differences, suggesting that a perceptual bias for snakes is present early in life and stable across infancy. In Experiment 2, infants fixated probes more quickly after viewing any trials that contained an angry face compared to trials that contained a happy face. Further, there were age‐related changes in infants' responses to face stimuli, with a general increase in looking time to faces before the probe and an increase in latency to fixate the probe after seeing angry faces. Together, this work suggests that different developmental mechanisms may be responsible for attentional biases for social vs. nonsocial threats.     

Outcomes of a revised apprentice carpenter fall prevention training curriculum

Falls from heights are a leading cause of morbidity and mortality among construction workers, especially inexperienced workers and those performing residential construction. This research reports changes in fall prevention behaviors following revision of fall prevention training in a union-based carpenters' apprenticeship program. We used a comprehensive needs assessment to identify gaps in apprentice carpenters' preparation to work at heights, used these results to guide a school-based fall prevention curriculum to fill these gaps, and measured the effects of the revised curriculum on knowledge, beliefs, and fall prevention behaviors.     

The Impact of Family Structure on Utilization of Preventive Care Services among Children under National Health Insurance in Taiwan

This study investigates the role of family structure in children’s access to preventive services in the context of a National Health Insurance (NHI) system. We analyzed the 2005 National Health Interview Survey in Taiwan to evaluate the impact of family structure on the utilization of preventive services, including well-child visits and non-free vaccinations. The extended family and single-father family were found to have a significant impact on care use in the unadjusted model even under NHI. However, after controlling for various health, demographic and socio-economic factors, our findings suggest that family structure does not influence the non-free use of vaccines, and financial constraints, instead, play an important role in making parents decide to have non-free vaccines. To further enhance the health and welfare of the children, our findings suggest that the NHI coverage of children’s vaccines might not be adequate and that non-free vaccines should be provided free to those families who cannot afford them.     

Model-robust supersaturated and partially supersaturated designs

Supersaturated designs are an increasingly popular tool for screening factors in the presence of effect sparsity. The advantage of this class of designs over resolution III factorial designs or Plackett–Burman designs is that n, the number of runs, can be substantially smaller than the number of factors, m. A limitation associated with most supersaturated designs produced thus far is that the capability of these designs for estimating g active effects has not been discussed. In addition to exploring this capability, we develop a new class of model-robust supersaturated designs that, for a given n and m, maximizes the number g   of active effects that can be estimated simultaneously. The capabilities of model-robust supersaturated designs for model discrimination are assessed using a model-discrimination criterion, the subspace angle. Finally, we introduce the class of partially supersaturated designs, intended for use when we require a specific subset of _m1$m_1$ core factors to be estimable, and the sparsity of effects principle applies to the remaining (m-_m1$m-m_1$) factors.
