The components of the female athlete triad do not identify all physically active females at risk

The purpose of the present study was to assess the effectiveness of the triad components (amenorrhoea, disordered eating, and osteoporosis) in identifying physically active women at risk of long-term health problems. Eighty-two females (mean age 31.1 years, s = 6.7; body mass 58.4 kg, s = 6.6; stature 1.65 m, s = 0.06) completed training, menstrual, and dietary questionnaires. Bone mineral density and size-adjusted bone mineral density were assessed at the femoral neck and lumbar spine using dual energy X-ray absorptiometry. Seventy-eight percent of participants were eumenorrhoeic, 20% were oligomenorrhoeic, and 2% were amenorrhoeic. Thirty-six percent and 55% reported disordered eating practices in the present and past respectively. Eighty-one percent, 17%, and 2% were classified as normal, osteopaenic, and osteoporotic at the femoral neck respectively; 92% were normal, 7% osteopaenic, and 1% osteoporotic at the lumbar spine. No significant differences in femoral neck size-adjusted bone mineral density were observed between eumenorrhoeic and oligo/amenorrhoeic participants (F(2,80) = 0.119, P = 0.73); eumenorrhoeic participants had significantly greater lumbar spine size-adjusted bone mineral density (F(2,80) = 9.79, P = 0.003). Disordered eating participants had significantly lower femoral neck size-adjusted bone mineral density than those reporting no disordered eating (F(2,80) = 13.816, P = 0.000). Twenty-two percent of participants fulfilled triad criteria, while 55% were "at risk" of long-term health problems. An accumulation of conditions resulted in lower lumbar spine size-adjusted bone mineral density (F(1,80) = 6.074, P = 0.004). The current triad components do not identify all women "at risk" and more appropriate criteria such as exercise-related menstrual alterations, disordered eating, and osteopaenia are suggested.     

Continual Improvement of Online and Blended Teaching Using Relative Proximity Theory

This article applies Deming's Plan‐Do‐Study‐Act (PDSA) cycle of continual improvement to a course taught with both blended and online sections. It uses Relative Proximity Theory, an extension of the Theory of Transactional Distance, to measure the quality of online/blended learning as a function of the obstacles to a student's full engagement with a course. These obstacles can arise because of the student's transactions with fellow students, with the instructor, with the course content, or from the instructional technology used in the course. Using stepwise multiple regression, the most significant obstacles can be identified. Once the obstacles are known, strategies to reduce them are planned and implemented. Logistic regression is used to determine if the realized reductions are statistically significant and for setting the stage for further improvements.     

Shifting norms and expectations for medical school leaders: a textual analysis of career advertisements 2000–2004 cf. 2010–2014

Leadership norms and expectations are continually evolving in higher education. Medical education is no exception to that trend, but shifts over time are intangible and difficult to measure. To explore emerging changes, the authors conducted a textual analysis of published career advertisements from 2000–2004 and 2010–2014. While a number of common themes united both time frames, new expectations emerge over a relatively brief period of time. The language of contemporary career advertisements conveys a landscape of leadership that is more collaborative, transparent, community-centred, accountable and team-based. This shift is significant, but perhaps less provocative than the absent discourses and contradictions. Despite the new leadership profile in 2010–2014, there is no mention of the important change management role required to guide organisational changes underway. Another contradiction relates to credentials. The contemporary advertisements fail to convey an updated career pathway and skill preparation aligned with the new leadership demands.     

Peer mentoring in engineering: (un)shared experience of undergraduate peer mentors and mentees

In this qualitative study, we explored the experiences of 26 engineering student mentors and mentees in a peer mentoring program. We found that mentors and mentees exploited the mentoring program’s fluid structure and situated social relationships to enact a specific type of academic/professional goal and identity conducive to their entry to one of two communities of practice, the on-campus engineering program community and the community of professional engineers. The mentoring program functioned as a social space in which identities of these students converged and diverged, creating a subtle tension and self-reflection in relation to the two different communities of practice that they pursued.     

Examining interactive whiteboard-based instruction on the academic self-efficacy,academic press and achievement of college students*

Abstract

The study reported here examined college students’ academic self-efficacy, ‘academic press’ and learning achievement, as well as the association between these three variables within learning contexts using interactive whiteboard-based instruction. A quasi-experimental study was conducted using a sample (n = 103) of first-year college students in China. Participants were taught English by either an interactive whiteboard-based or traditional lecture-based instructional approach for three months. The results showed that the interactive whiteboard-based instructional intervention cultivated higher levels of academic press and academic self-efficacy among students and a significant, positive correlation was identified between these two variables. Students’ learning achievement was not affected by the instructional intervention. These results indicate that interactive whiteboard-based instruction offers some distinct benefits. In future work, additional research is needed to clarify how the instructional model relates to understanding learning achievement.
