Relationship between laboratory-measured variables and heart rate during an ultra-endurance triathlon

The aim of the present study was to examine the relationship between the performance heart rate during an ultra-endurance triathlon and the heart rate corresponding to several demarcation points measured during laboratory-based progressive cycle ergometry and treadmill running. Less than one month before an ultra-endurance triathlon, 21 well-trained ultra-endurance triathletes (mean +/- s: age 35 +/- 6 years, height 1.77 +/- 0.05 m, mass 74.0 +/- 6.9 kg, = 4.75 +/- 0.42 l x min(-1)) performed progressive exercise tests of cycle ergometry and treadmill running for the determination of peak oxygen uptake (VO2peak), heart rate corresponding to the first and second ventilatory thresholds, as well as the heart rate deflection point. Portable telemetry units recorded heart rate at 60 s increments throughout the ultra-endurance triathlon. Heart rate during the cycle and run phases of the ultra-endurance triathlon (148 +/- 9 and 143 +/- 13 beats x min(-1) respectively) were significantly (P < 0.05) less than the second ventilatory thresholds (160 +/- 13 and 165 +/- 14 beats x min(-1) respectively) and heart rate deflection points (170 +/- 13 and 179 +/- 9 beats x min(-1) respectively). However, mean heart rate during the cycle and run phases of the ultra-endurance triathlon were significantly related to (r = 0.76 and 0.66; P < 0.01), and not significantly different from, the first ventilatory thresholds (146 +/- 12 and 148 +/- 15 beats x min(-1) respectively). Furthermore, the difference between heart rate during the cycle phase of the ultra-endurance triathlon and heart rate at the first ventilatory threshold was related to marathon run time (r = 0.61; P < 0.01) and overall ultra-endurance triathlon time (r = 0.45; P < 0.05). The results suggest that triathletes perform the cycle and run phases of the ultra-endurance triathlon at an exercise intensity near their first ventilatory threshold.     

Five critiques of the open educational resources movement

This paper will review existing literature on Open Educational Resources (OER). It is intended to examine and critique the theories which underpin the promotion of OER in higher education, not provide guidance on their implementation. (1) I will introduce the concepts of positive and negative liberty to suggest an under-theorisation of the term ‘open’. (2) OER literature will be shown to endorse a two-tiered system, in which the institution is both maintained and disaggregated. (3) I will highlight a diminishing of the role of pedagogy within the OER vision and the promotion of a learner-centred model for education. (4) This stance will be aligned with humanistic assumptions of unproblematic self-direction and autonomy. (5) I will discuss the extent to which the OER movement aligns itself with economically orientated models of the university. I offer these critiques as a framework for the OER movement to develop as a theoretically rigorous area of scholarship.     

Research and evaluation in sexuality education: an allegorical exploration of complexities and possibilities

Defining ‘success’ in sexuality education solely in terms of quantitative outcome measures is woefully inadequate. All too often, such measures presuppose and perpetuate a narrow and overly instrumental view of sexuality and education. Research and evaluation favouring quantitative measures of effectiveness tend to amplify short‐term results and mediocre ends at the expense of more substantive insight into the complexities and nuances of human action and good practice. The paper begins with a true story involving a teenager and high‐risk behaviours. This story serves as a basis for an allegorical exploration of programme development, goals and vision. The allegory offers a context for thinking about the importance of research and evaluation methods that focus on expressive action, agency and symbolic metaphorical thinking as opposed to measurable behaviours and linear logical thinking.     

A Profile of Giving Patterns and Donor Behavior at a Suburban Community College

Community colleges have become increasingly reliant on diversifying their revenue sources, and turning to private fund raising has become a common strategy for many of them. Although fund raising has been a common practice in higher education since its inception, it has only emerged in the two-year college sector in the past several decades. The current study sought to identify donors at a case study, suburban community college, specifically exploring giving patterns over time and testing the conceptual framework of a pyramid of giving that overlays institutional involvement and commitment with giving levels. Major infrastructure inconsistencies prevented much of the framework testing, but data were capable of creating an initial donor and giving profile for a typical community college. This profile demonstrated that board members and employees were the most loyal and consistent in making contributions, but that these gifts often were stable over time and did not increase to become major gifts. Also, private business and industry gifts were often given at the same level as individual gifts, perhaps illustrating the responsiveness and cooperation between community colleges and the local workforce.     

2008 Community College Futures Assembly Focus: Change Or Die—Keys to Enacting Change in the Community College

The Community College Futures Assembly has served as a national, independent policy thinktank since 1995. Its purpose is to articulate the critical issues facing American community colleges and recognize innovative programs. Convening annually in January in Orlando, Florida, the Assembly offers a learning environment where tough questions are raised, critical issues are discussed, and policy implications are vetted. The focus for the 2008 Community College Futures Assembly was change, a theme taken from the book, Change or Die. This special focus issue of the Community College Journal of Research and Practice highlights the best practices of 30 Bellwether trend-setting institutions.
