Background: The factors influencing parents’ willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents’ willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. Methods: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of (...) three consent and data-sharing scenarios. Results: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50–59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one’s child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. Conclusions: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. (shrink)

This article addresses the demand for global content knowledge that the process of internationalization has placed on the preparation of social studies teachers. Drawing on scholarship about global perspectives in teacher education, this study examined what one cohort of preservice teachers learned about globalization during participation in a three-week, web-based, international relations simulation. The unit was part of a methods course designed to prepare preservice teachers to teach global issues and internationalize the curriculum. International simulations have long been touted as (...) a means for learning challenging knowledge about global issues yet are rarely studied in teacher education. This qualitative study drew on concept maps and written responses completed before and after the simulation to document the preservice teachers’ learning. The analysis generated two findings: (1) preservice teachers acquired a shared, conceptual vocabulary for globalization that included the events and actors represented in the simulation; and (2) they also demonstrated a more systematic and critical understanding of the ways that power and conflict shaped the events and actors. The study contributes to the question of what teachers need to know to teach with global perspectives and how efforts to internationalize teacher education programs can foster such knowledge.

Motivated by a recent proof of free choices in linking equations to the experiments they describe, I clarify some relations among purely mathematical entities featured in quantum mechanics (probabilities, density operators, partial traces, and operator-valued measures), thereby allowing applications of these entities to the modeling of a wider variety of physical situations. I relate conditional probabilities associated with projection-valued measures to conditional density operators identical, in some cases but not in others, to the usual reduced density operators. While a fatal (...) obstacle precludes associating conditional density operators with general non-projective measures, tensor products of general positive operator-valued measures (POVMs) are associated with conditional density operators. This association together with the free choice of probe particles allows a postulate of state reductions to be replaced by a theorem. An application shows an equivalence between one form of quantum key distribution and another with respect to certain eavesdropping attacks. (shrink)

This article examines Bourdieu’s adoption of Husserl’s concept of ‘doxa’ and argues that Bourdieu’s reading of Husserl overpolarizes doxa and reflexivity. The article argues that there is a need for Bourdieusian sociology to adopt a more complex interpretation of Husserlian phenomenology in order to understand the potential range of states of consciousness between doxa and reflexivity. In contrast to Bourdieu’s reading of Husserl, this article argues that the philosophical underlabouring for an adequate understanding of doxa is now available within recent (...) Husserlian studies which marks a radical development from earlier readings in the ‘sociology of consciousness’. (shrink)
