#SELFIES at the 2016 Rio Olympics: Comparing Self-Representations of Male and Female Athletes from the U.S. And China

Social media provides athletes an efficient platform on which to build and maintain their online image. Applying the self-representation theory of Goffman (1959), this study explored the gendered differences between the self-portrayals of U.S. and Chinese athletes. Findings suggest that hegemonic gender norms still had a strong hold on Chinese athletes’ self-disclosure, whereas minimal gender differences emerged between male and female U.S. athletes. Results suggested that cultural background had a substantial impact on self-representation for all participants. Although athletes might claim agency when presenting themselves on social media, the practice of self-portrayal should be examined within specific cultural contexts.     

Moral Economies in Science: From Ideal to Pragmatic

In the following pages we discuss three historical cases of moral economies in science: Drosophila genetics, late twentieth century American astronomy, and collaborations between American drug companies and medical scientists in the interwar years. An examination of the most striking differences and similarities between these examples, and the conflicts internal to them, reveals constitutive features of moral economies, and the ways in which they are formed, negotiated, and altered. We critically evaluate these three examples through the filters of rational choice, utility, and American pragmatism, using the latter to support the conclusion that there is no single vision of moral economies in science and no single theory—moral, political, social—that will explain them. These filters may not be the only means through which to evaluate the moral economies examined, but aspects of each appear prominent in all three cases. In addition, explanations for decisions are often given in the language of these theories, both at the macro (policy) level and at the local level of the moral economies we discuss. In light of such factors, the use of these frameworks seems justified. We begin with an attempt to define the nature of moral economies, then move to a consideration of scientific communities as moral communities operating within material and other constraints which we relate to wider questions of political economy and societal accountabilities.

Fostering Third-Grade Students’ Use of Scientific Models with the Water Cycle: Elementary teachers’ conceptions and practices

Elementary teachers play a crucial role in supporting and scaffolding students’ model-based reasoning about natural phenomena, particularly complex systems such as the water cycle. However, little research exists to inform efforts in supporting elementary teachers’ learning to foster model-centered, science learning environments. To address this need, we conducted an exploratory multiple-case study using qualitative research methods to investigate six 3rd-grade teachers’ pedagogical reasoning and classroom instruction around modeling practices (construct, use, evaluate, and revise) and epistemic considerations of scientific modeling (generality/abstraction, evidence, mechanism, and audience). Study findings show that all teachers emphasized a subset of modeling practices—construction and use—and the epistemic consideration of generality/abstraction. There was observable consistency between teachers’ articulated conceptions of scientific modeling and their classroom practices. Results also show a subset of the teachers more strongly emphasized additional epistemic considerations and, as a result, better supported students to use models as sense-making tools as well as representations. These findings provide important evidence for developing elementary teacher supports to scaffold students’ engagement in scientific modeling.     

Factors associated with minimal changes in countermovement jump performance throughout a competitive division I collegiate basketball season

ABSTRACT

The purpose of the study was to assess factors that contribute to countermovement jump (CMJ) performance in women’s basketball athletes. Thirteen female athletes participated and were tested for maximal oxygen uptake (VO_2max) and heart rate (HR_max). Athletes were monitored, daily for a total of 21 weeks with heart rate-based wearable devices and CMJ performance and body weight were tested weekly after one day of recovery. 3-jump average height (CMJ_avg), maximum height jump (CMJ_max), and CMJ power (Watts) were calculated and recorded. Playing intensities >85% HR_max, HR_avg, HR_max and training load were averaged for three consecutive days prior to the recovery day. After the season, data was grouped as changes in CMJ power from week one: Large (≤ ?4.39% change), Moderate (?4.4% to ?0.62% change), and Minimal (≥ ?0.61% change) changes. Fixed-effects models revealed a main effect of group (p ≤ 0.05) for CMJ_avg, CMJ_max, VO_2max, weekly percent changes in body weight and for 3-day training load, HR_avg, and playing time at >85% HR_max. When athletes experienced minimal changes in CMJ performance, relative to large changes, they produced greater power, jumped higher, avoided negative changes in weekly body weight, had a greater preseason VO_2max and 3-day average workloads appeared to have an impact on CMJ performance     

Providing a clearer view: An examination of transparency on local government websites

This study examines the role of content professionalism and public outreach, along with partisanship in the availability of online local public information. Comparing county and school board websites in Florida, the author suggests that online public records serve as a proxy for the entity's overall level of transparency. A content analysis of 134 local government websites reveals that school boards had a higher level of transparency than counties in Florida, while websites with a more professional look and those located in communities with a high Republican proportion had greater transparency than others. Finally, implications for scholars and government leaders are discussed.     

Reaching Out: Newspaper Credibility Among Young Adult Readers

The researchers examined student perceptions of campus and community newspaper credibility at the University of Florida using a Web survey (n = 1,906) of those enrolled in a general education class. A moderate correlation (r = .28) existed between college newspaper credibility and community newspaper credibility. Using hierarchical linear regression, the researchers found interest in news content to be a statistically significant predictor of credibility for both local newspapers and college newspapers. In addition, students whose parents encouraged them to read a newspaper found both newspapers more credible than did their peers, and exposure to a newspaper was found to be a strong predictor of credibility for that newspaper. Finally, the results of this case study also suggest White respondents find local newspapers more credible than other races. Implications for researchers and practitioners were discussed.
