Adrian Peterson and the “Wussification of America”: Football and Myths of Masculinity

Twitter has become a unique site for making sense of public discussions about authority and morality in the United States. This article addresses these discussions by analyzing the elements of conservative discourse that claim the health of the nation is in decline because of a diminished emphasis on masculine leadership. There is a long tradition of conservative politicians in the United States warning against “soft” or “weak” figures of authority. Such conversations take place within a range of contexts, including the sport of football. As a means to engage hegemonic masculine authority from a critical perspective, this article investigates Twitter users’ various reactions to Adrian Peterson’s suspension due to his disciplining his child with a “switch.”     

Insights from industry: a quantitative analysis of engineers' perceptions of empathy and care within their practice

This study focuses on two seldom-investigated skills or dispositions aligned with engineering habits of mind – empathy and care. In order to conduct quantitative research, we designed, explored the underlying structure of, validated, and tested the reliability of the Empathy and Care Questionnaire (ECQ), a new psychometric instrument. In the second part, we used the ECQ to explore the perceptions of empathy and care of alumni/ae of an internationally ranked US institution, along with how perceptions differed by work experience and gender. Results show that participants perceived empathy and care to be important in multiple respects, most notably in relational aspects of engineering practice. Engineers with more engineering experience were more likely to perceive empathy and care as existing in engineering practice and as important to their work. While these phenomena are sometimes depicted as feminine qualities, we found no gender differences among our respondents.     

‘Voodoo maths’, asymmetric dependency and maths blame: why collaboration between school science and mathematics teachers is so rare

Mathematical reasoning and tools are intrinsic to science, yet the close and dependent relationship science has to mathematics is not reflected in either school education or science education research. This paper asks what the barriers are to a mutually beneficial relationship between the two disciplines. A two-phase qualitative interview study was used to explore the relationship between school science and mathematics education through the perspectives of science and mathematics education policy-makers and of teachers in departments which are unusual in collaborating. In total there were 36 participants. Interview data were analysed using thematic analysis. Findings show that there is an asymmetry in the dependency between school science and mathematics: science is dependent on mathematics but the reverse is not true. We discuss three consequences of this asymmetric dependency: there is greater benefit for science from any collaboration; ‘maths blame’ can arise from science teacher frustration; and science educators may believe they should have some ownership of the mathematics curriculum. Asymmetry of dependency, and therefore of benefit, will make it very difficult for mathematics and science to work together in a way which is genuinely mutually beneficial.     

The effect of plot explicit,educational explicit,and implicit inference information and coviewing on children's internal and external cognitive processing

Parental coviewing – the act of being present when a child is watching television – can influence the child’s cognitive processing and emotional reactions. This study investigated the role coviewing has on the child’s cognitive processing – which is evidenced by the phasic psychophysiological orienting response to three types of information: plot explicit, educational explicit, and implicit inference. An experiment was conducted that measured the heart rate of children (N?=?88; mean age?=?9.12 years) while watching messages either with or without a parent present in the room. It was predicted, and found, that coviewing leads to greater resource allocation to encoding the message – as indicated by phasic cardiac deceleration, and that information that required internal processing, such as plot explicit or implicit inferential content, leads to greater resources allocated to internal processing – as indicated by phasic cardiac acceleration. Implications for parental mediation strategies and educational television programming are given.     

A sustainable model for OpenCourseWare development

The purposes of this study were to (a) determine the cost of converting BYU Independent Study’s e-learning courses into OpenCourseWare, (b) assess the impact of opening those courses on paid enrollment in the credit-bearing versions of the courses, and (c) use these data to judge whether or not an OpenCourseWare program could be financially self-sustaining over the long-term without grant monies or other subsidies. The findings strongly suggest that the BYU Independent Study model of publishing OpenCourseWare is financially self-sustaining, allowing the institution to provide a significant public good while generating new revenue and meeting its ongoing financial obligations.     

Pre-exposure enhances recovery of conditioned responding after extinction

Four experiments used a within-subjects design with rats to study the effects of preexposure on the restoration of fear responses (freezing) to an extinguished conditioned stimulus (CS). In each experiment, rats were preexposed to one CS (A), but not to another (B), and then were exposed to pairings of each of these CSs with an aversive unconditioned stimulus (US). In each experiment, there was less freezing to A than to B across extinction, showing a latent inhibitory effect of preexposure. There was no differential recovery to A and B following either a US reexposure (Experiment 1) or a delay interval (Experiment 2). However, when a delay interval included US reexposure, there was greater recovery to the preexposed CS, A, than to the nonpreexposed CS, B (Experiments 1, 3, and 4). These results suggest that the effects of US reexposure and delay combine to affect recovery from the depressive effects of CS-alone exposure. The results are consistent with the view that US reexposure produces better mediated conditioning of CSs that are strongly associated with the context. The results may additionally reflect an effect of preexposure on the learning produced by extinction.

If you cannot block, you better run: Small firms, cooperative innovation, and appropriation strategies

This empirical study examines small firms’ strategies for capturing returns to investments in innovation. We find that small firms’ strategies are qualitatively different from those found in earlier studies of both small and large firms. Most of the small firms examined here find informal means of protection, such as speed to market or secrecy, more important than patenting. Only firms with university cooperation—typically R&D intensive and science-based small firms—were likely to identify patents as the most important method of appropriating innovation returns in their field. Thus, the strategic choice for most small firms is between secrecy and speed to market. Firms that cooperate in innovation with horizontal partners or significantly depend on vertical partners tend to prefer speed, whereas process innovators with modest R&D investments or few cooperative R&D activities display a preference for trade secrets. Indeed, cooperation activities greatly influence the choice of intellectual property strategy for small firms. Earlier research has emphasized patents and trade secrets as key strategies of appropriation, yet these strategies do not appear to be very beneficial for small firms engaged in cooperative innovation. These results raise policy questions regarding the functionality of the existing system of intellectual property rights.
