Can Technology Decrease Sexual Risk Behaviors among Young People? Results of a Pilot Study Examining the Effectiveness of a Mobile Application Intervention

College students represent an important population for studying and understanding factors that influence sexual risk given the populations' high risk of sexually transmitted infections and unintended pregnancies. Using a quasi-experimental design, the efficacy of a brief and theory-driven mobile application intervention designed to decrease sexual risk behaviors among young college students (N = 118) was tested. Ninety-six percent (n = 114) of the participants showed an increase in contraceptive use knowledge from pretest to posttest (p = .013). Participants did not show a statistically significant change in intention to reduce sexual risk behaviors or actual risk reduction. This study supports the use of technology to educate college students about sexual health.     

A Pilot Study Examining Religious Organization Affiliation,Sexual Health Information Sources,and Sexual Behaviors Among College Students

We conducted an online survey to examine religiosity, sexual health knowledge, and behavior and sexual health information sources among undergraduate students affiliated with student religious organizations (n?=?45) and unaffiliated students (n?=?82). Analyses included Fisher’s exact tests, t-tests, and exact regression models. Students reporting religious affiliation considered religious sources to be believable (p?=?.004 for sexual health; p?p?=?.0042). Although religiously affiliated students reported fewer sexual partners in the past year (p?=?.020), their reported condom use was not significantly different from that of unaffiliated students. Future research should explore the focus and content of romantic relationship information provided by student religious organizations. Health practitioners and educators should consider strategies for collaborating with religious organizations to meet the information needs of these students.     

The role of authentic teaching cases and mastery approach goals in online pre-service teachers’ self-regulated learning

Instructional methods in higher education are changing in response to the growing popularity for distance learning courses. Investigating methods of instruction that will assist in the manner that coursework is taught in online courses is therefore a significant enterprise to research. Specifically, examining the relation between theory and practice in programs of teacher education where application is an integral part of the curriculum as well as students’ future career is of utmost importance. Instruction using the case study method enables instructors to involve their students with the realities of teaching using scenarios built around authentic educational dilemmas, where students can problem-solve varying outcomes and generate possible solutions from multiple theoretical viewpoints. Self-regulated learning has been consistently shown to be a fundamental component in the academic success of online learners. Existing research studies on distance learners has specifically shown mastery-approach goals to be predictive of self-regulated learning. This study found significant relationships between the use of authentic case studies in online preservice teaching, self-regulation, and mastery approach goals. Additionally, the results of this study also identified that the relationship between self-regulation and mastery approach goals was strengthened when using case studies that were authentic.

     

Microanalytic case studies of individual participation patterns in an asynchronous online discussion in an undergraduate blended course

This study presents three case studies of students' participation patterns in an online discussion to address the gap in our current understanding of how individuals experience asynchronous learning environments. Cases were constructed via microanalysis of log-file data, post contents, and the evolving discussion structure. The first student was Thorough, reading all the posts in the forum in sequence, revisiting different posts multiple times, and creating posts outside of the discussion tool. The second student was Self-Monitoring, revisiting his own posts multiple times, checking the discussion frequently for replies, and replying to or editing his posts in response. Finally, the third student was Independent, using the forum as a tool for her own individual reflection. The behaviors found for these cases are aligned with a theoretical taxonomy for participation proposed by Knowlton (2005). The value and limitations of the microanalytic case study approach are discussed, and implications for research and practice are suggested.     

Mobility,citizenship, and “American women on the move” in the 1977 International Women’s Year torch relay

This essay examines the 1977 International Women’s Year torch relay from Seneca Falls to Houston to demonstrate the rhetoricity of mobility and theorize running as a mode of public address. The relay used the velocity of running to centralize athleticism and the female athlete as a crucial site for liberal feminist citizenship claims in 1977 in the context of Title IX and the struggle over the Equal Rights Amendment. The runners’ movement through space and place advanced a discursive performance of citizenship as they traversed the South. This analysis reveals mobility as a theoretical framework for rhetorical scholars interested in space, place, citizenship, and social movement.     

Acute ingestion of beetroot juice does not improve short-duration repeated sprint running performance in male team sport athletes

ABSTRACT

The effects of acute ingestion of nitrate on short-duration repeated sprint performance (RSP) are unclear. This study investigated the effect of acute ingestion of beetroot juice on a test of RSP in team sport athletes. Sixteen male team sport athletes undertook four trials using a 40 m maximum shuttle run test (MST), which incorporates 10 × 40 m shuttle sprints with 30 s between the start of each sprint. Two familiarisation trials, followed by nitrate-rich beetroot juice (BR; ~6 mmol nitrate) and nitrate-depleted beetroot juice (PLA; ~0.0034 mmol nitrate) trials were completed in a randomised, double-blind manner. Ingestion of beetroot juice 3 h prior to exercise elevated plasma nitrate concentrations ~6-fold in BR (BR, 413 ± 56 μM; PLA, 69 ± 30 μM; P < 0.001). RSP, assessed by sprint performance decrement (S_dec; %), did not differ (P = 0.337) between BR (5.31 ± 2.49%) and PLA (5.71 ± 2.61%). There was no difference between trials for total sprint time (P = 0.806), fastest sprint (P = 0.341), slowest sprint (P = 0.787), or post-exercise blood lactate concentration (BR, 11.8 ± 2.5 mM; PLA, 12.2 ± 2.3 mM; P = 0.109). Therefore, acute ingestion of beetroot juice did not improve a test of short-duration RSP in team sport athletes.
