Testosterone during Pregnancy and Gender Role Behavior of Preschool Children: A Longitudinal, Population Study

Levels of testosterone (T) and sex hormone–binding globulin (SHBG) were measured in blood samples from pregnant women and related to gender role behavior in 342 male and 337 female offspring at the age of 3.5 years. Gender role behavior was assessed using the Pre–School Activities Inventory, a standardized measure on which a parent indicates the child's involvement with sex–typical toys, games, and activities. Levels of T, but not SHBG, related linearly to gender role behavior in preschool girls. Neither hormone related to gender role behavior in boys. Other factors, including the presence of older brothers or sisters in the home, parental adherence to traditional sex roles, the presence of a male partner in the home, and maternal education, did not relate to gender role behavior in this sample and did not account for the relation observed between T and behavior. Although other, unmeasured factors may explain the relation, the results suggest that normal variability in T levels prenatally may contribute to the development of individual differences in the gender role behavior of preschool girls.     

Youth Disciplinary Identification During Participation in Contemporary Project-Based Science Investigations in School

Recent science educational policy reform efforts call for a shift toward practice-focused instruction in kindergarten–Grade 12 science education. We argue that this focus on engaging students in epistemic practices of science opens up new possibilities for the design of learning environments that support the stabilization of learners’ science-linked identities. Learning environments often assume that youth come to them without relevant identity resources to contribute or that the learning environment has no bearing on the disciplinary identification of individuals. We conducted this research while developing a year-long course to teach high school biology by engaging youth in interest-driven projects focused on contemporary topics. We explored how engaging youth in the epistemic practices of science in culturally expansive ways supported their science-linked identification. We propose a model grounded in social practice theory that describes aspects of students’ stabilization of disciplinary identities. We found that (a) deepening participation in scientific practices is linked to whether or not youth have opportunities to coordinate their engagement with their existing identities; and (b) material, relational, and ideational identity resources and qualities of the learning environment mediate how youth stabilize disciplinary identities in interactional moments.     

Increasing the Reliability of Ability-Achievement Difference Scores: An Example Using the Kaufman Assessment Battery for Children

In this study, we focused on increasing the reliability of ability-achievement difference scores using the Kaufman Assessment Battery for Children (KABC) as an example. Ability-achievement difference scores are often used as indicators of learning disabilities, but when they are derived from traditional equally weighted ability and achievement scores, they have suboptimal psychometric properties because of the high correlations between the scores. As an alternative to equally weighted difference scores, we examined an orthogonal reliable component analysis, (RCA) solution and an oblique principal component analysis (PCA) solution for the standardization sample of the KABC (among 5- to 12-year-olds). The components were easily identifiable as the simultaneous processing, sequential processing, and achievement constructs assessed by the KABC. As judged via the score intercorrelations, all three types of scores had adequate convergent validity, while the orthogonal RCA scores had superior discriminant validity, followed by the oblique PCA scores. Differences between the orthogonal RCA scores were more reliable than differences between the oblique PCA scores, which were in turn more reliable than differences between the traditional equally weighted scores. The increased reliability with which the KABC differences are assessed with the orthogonal RCA method has important practical implications, including narrower confidence intervals around difference scores used in individual administrations of the KABC.

Putting mobile application privacy in context: An empirical study of user privacy expectations for mobile devices

Users increasingly use mobile devices to engage in social activity and commerce, enabling new forms of data collection by firms and marketers. User privacy expectations for these new forms of data collection remain unclear. A particularly difficult challenge is meeting expectations for contextual integrity, as user privacy expectations vary depending upon data type collected and context of use. This article illustrates how fine-grained, contextual privacy expectations can be measured. It presents findings from a factorial vignette survey that measured the impact of diverse real-world contexts (e.g., medical, navigation, music), data types, and data uses on user privacy expectations. Results demonstrate that individuals’ general privacy preferences are of limited significance for predicting their privacy judgments in specific scenarios. Instead, the results present a nuanced portrait of the relative importance of particular contextual factors and information uses, and demonstrate how those contextual factors can be found and measured. The results also suggest that current common activities of mobile application companies, such as harvesting and reusing location data, images, and contact lists, do not meet users’ privacy expectations. Understanding how user privacy expectations vary according to context, data types, and data uses highlights areas requiring stricter privacy protections by governments and industry.     

Pharmacist perception and use of UpToDate?

A cross-sectional survey of a convenience sample of 1,199 pharmacists was conducted to describe pharmacists'' use and perception of UpToDate®. Of 472 (39%) respondents, 217 (46%) reported using UpToDate. Most respondents who used or had heard of UpToDate indicated willingness to change a treatment plan based on UpToDate recommendations (77%). Many believed that UpToDate is updated weekly (31%) or monthly (49%) and that all articles undergo external peer review (51%). In conclusion, the majority of respondents reported that they would adjust drug therapy based on UpToDate recommendations; however, many pharmacists may hold misconceptions regarding the updating and peer-review processes.     

Theorizing Communication Orientations of Privilege: How White Discourses (De) Construct Australian Aboriginals

We conducted a discourse analysis of Australians' conversations about race, exploring communication that (re)produces and decenters whiteness. We identified 23 communication practices, organized into four orientations (unity, separation, monologue, and dialogue), describing how those with power talk about those without power and (fail to) balance tensions between similarity and difference. Orientations of unity, monologue, and separation serve antidialogic functions by obstructing transformative thinking, de-legitimizing Aboriginal experiences, and reifying whiteness. Findings suggest it is possible, but rare, for individuals to engage in intercultural dialogue about race. Understanding communication orientations of privilege is a step towards facilitating talk that disrupts whiteness.     

Do zoo visitors come to learn? An internationally comparative,mixed-methods study

Zoo visitors go to see animals, but are they there to learn? This mixed-methods study examines visitor learning from both zoos’ and visitors’ perspectives using qualitative and quantitative data. Five hundred and forty zoo visitor interviews from nine case studies provide insight into visitor intentions, which indicate that the majority of visitors (72%) arrive at zoos with a learning agenda. Over 170 zoos across 48 countries also report, via an online questionnaire, that the majority of their visitors come to learn. In contrast, however, 28 face-to-face zoo education staff interviewed at the nine case study sites suggests a different conclusion. The study also indicates that zoos appear to determine visitors’ intentions through a number of methods, but are most heavily reliant on informal measures with only 15% of zoos using both formal and informal processes. Juxtaposing these findings suggests that zoos’ reliance on informal measures of visitor intentions appears to provide them with a less than accurate picture of their visitors’ learning agendas.     

Disrupting racialization: considering critical leadership in the field of physical education

Background: The field of physical education (PE), overlapping as it does with the field of sport, has been critiqued for marginalizing those positioned as ‘different’. This difference is typically conceptualized in regard to a white, masculine, heterosexual, and able-bodied norm. Students who do not identify as white are not represented in any significant way in physical education discourses, culture, or the demographics of PE teachers in many international contexts.

Purpose: This article explores links between the literature in critical leadership and physical education. Drawing on the theoretical foundations of transformational leadership, critical pedagogy, and critical race theory, we draw links between the field of PE and applied critical leadership.

Design and analyses: Drawing on the theoretical tools of Bourdieu, we argue that physical education can be conceptualized as a field of practice. As such, the field values contain certain practices and norms. We argue that disrupting these norms relies on leadership in the field and may require insights from other fields, in this case applied critical leadership.

Conclusion: We conclude that leaders (both teachers and teacher educators) in the field of PE have a responsibility to take up practices which work against racialization and challenge current norms. This is both a theoretical and pedagogical challenge but can begin in classrooms.
