Missing links in nanomaterials governance: bringing industrial dynamics and downstream policies into view

In this article we explore some of the analytical and policy implications of widening the focus of nanomaterials governance from risk regulation to the broader issue of the purposeful direction of the innovation process. We focus on the impact of industrial activities on nanotechnology governance, arguing that the specific characteristics of the industrial dynamics of nanomaterials—flexibility in applications and distributed innovation—limit and enable different potential interventions to shape technology. In particular, these characteristics exacerbate the difficulties of attempting to directly influence innovation trajectories. Under these conditions, we argue that policies for nanomaterials governance need to be broadened. The prevailing emphasis in the UK on policy initiatives ‘upstream’ in the R&D process, while commendable, should be complemented with policies aimed further ‘downstream’ at potential users of nanomaterials, such as renewable energy procurement or housing regulations in order to modulate technological development towards socially desirable goals.     

Preliminary Development of the Student Perceptions of School Safety Officers Scale

Research suggests that the safer students feel at school, the more likely they are to feel connected and able to focus on learning. Thus, measuring students’ experiences with a school safety officer (SSO) is essential to understand the connection between officer engagement and students’ safety. This study’s purpose was to evaluate a SSO scale among 1,065 adolescents. Results suggest the SSO scale displayed excellent internal consistency estimates, construct validity via factor analysis, convergent validity with the School Climate Measure, discriminant validity with key demographic variables, and known-groups validity among students who reported fighting at school. Positive perceptions of SSOs also significantly increased with frequency of contact. The SSO scale is a preliminarily valid measure, potentially useful in research, screenings, and/or evaluation efforts to improve student engagement with SSOs.     

A Comparison of Different Age Estimation Methods of the Adult Pelvis

The adult human pelvis is useful to estimate age because it contains three age indicators—the pubic symphysis, auricular surface, and acetabulum. This study tested the accuracy, inaccuracy, and bias of age estimation from the Suchey‐Brooks pubic symphysis, Osborne auricular surface, Rissech and Calce acetabulum aging methods, and a summary age of these indicators. The study sample consisted of 212 White individuals with known age and sex from the William M. Bass Donated Skeletal Collection. The Rissech method performed the best, was the most accurate method with smallest inaccuracy and bias, followed by the Osborne, Suchey‐Brooks, summary age, and then Calce methods. Though the Pearson correlation showed only the Suchey‐Brooks method to correlate significantly with known age, it is likely the Suchey‐Brooks study sample coincidentally reflected the age distribution of this test sample. Results suggested that Bayesian prediction may improve age estimation and should be applied to other age indicators.

Competence-Related Abilities and Psychiatric Symptoms: An Analysis of the Underlying Structure and Correlates of the MacCAT-CA and the BPRS

The current study used confirmatory factor analysis to examine the factor structures of two instruments commonly used in the assessment of competency to stand trial--the MacArthur Competence Assessment Tool--Criminal Adjudication (MacCAT-CA) and the Brief Psychiatric Rating Scale (BPRS). Results revealed support for the three-subscale factor structure of the MacCAT-CA defined by the authors of the instrument; for a slightly altered three-factor structure defined by Zapf, Skeem, and Golding (2005, Psychological Assessment, 17, 433-445); and for the four symptom clusters of the BPRS as defined by Hedlund and Vieweg (1980, Journal of Operational Psychiatry, 11, 48-63). In addition, exploratory factor analysis of all 24 items of the BPRS revealed a five-factor structure. Correlations between psychiatric symptoms, symptom clusters, and competence-related abilities were also examined using the previously identified and the newly identified factor structures of the MacCAT-CA and the BPRS. Significant relations between symptoms and psycholegal abilities are discussed.
