Durable Research,Portable Findings: Rhetorical Methods in Case Study Research

ABSTRACT

Case studies have been a central methodology employed by scholars working in the rhetoric of science and technical communication. However, concerns have been raised about how cases are constructed and collected, and what they convey. The authors reflect on how rhetoricians of science and technical communication researchers can – and do – construct a variety of case-based mixed-methods studies in ways that may make our research more portable and durable without undercutting the important and central role of case-based analysis.     

Dose-response relationship between weekly resistance training volume and increases in muscle mass: A systematic review and meta-analysis

The purpose of this paper was to systematically review the current literature and elucidate the effects of total weekly resistance training (RT) volume on changes in measures of muscle mass via meta-regression. The final analysis comprised 34 treatment groups from 15 studies. Outcomes for weekly sets as a continuous variable showed a significant effect of volume on changes in muscle size (P = 0.002). Each additional set was associated with an increase in effect size (ES) of 0.023 corresponding to an increase in the percentage gain by 0.37%. Outcomes for weekly sets categorised as lower or higher within each study showed a significant effect of volume on changes in muscle size (P = 0.03); the ES difference between higher and lower volumes was 0.241, which equated to a percentage gain difference of 3.9%. Outcomes for weekly sets as a three-level categorical variable (<5, 5–9 and 10+ per muscle) showed a trend for an effect of weekly sets (P = 0.074). The findings indicate a graded dose-response relationship whereby increases in RT volume produce greater gains in muscle hypertrophy.

网络游戏:未来有多远?

Online games, the latest craze for the rapidly expanding video-game industry, still face a series of growing pains. Despite a growing base of players, a host of questions have given companies pause when it comes to online games, ranging from bandwidth (带宽) issues to the high cost of developing games to determining how much     

Undergraduate Research Mentoring: Obstacles and Opportunities

Researchers and policy-makers in higher education increasingly espouse the view that undergraduate students should have the opportunity to learn about scholarship and research in the context of faculty-mentored research experiences. There is mounting consensus that mentored undergraduate research should be standard pedagogical practice in all undergraduate disciplines. Although high-impact, mentored undergraduate research, scholarship, and creative work (URSCW) requires significant resources, with faculty time and energy foremost among them. This article addresses the current gap between aspiration and effective execution of well-mentored URSCW, including the most prevalent obstacles (e.g. institutional, departmental, individual) to undergraduate mentoring. This article is written for academic leaders and institutional officers. It concludes with several specific recommendations for increasing the frequency of mentored URSCW experiences for undergraduates.
