Uncertainty,environmental policy and social learning

This note puts the research project which led to this Special Issue in the context of developments in and around environmental policy over the past two decades, from the perspective of someone closely involved. It links political and institutional problems over sustainable development to the changing role and authority of science in contemporary society, and to the new kind of emphasis on social learning to be found in the papers that follow.     

Boyer in the Middle: Second Generation Challenges to Emerging Scholarship

This article reports on an examination of the distinctive second-generation challenges and opportunities faced by an early institutional adopter of the Boyer model of scholarship. Following the first cohort of faculty to be reviewed for tenure and promotion based on these criteria, we report the results of a survey designed to determine the perceptions of faculty and administrators of the degree to which emerging forms of scholarship had been integrated into the university culture including factors such as institutional identity, support structures, and faculty participation. This case study sheds light on the process of adaptation at this single institution and provides glimpses of how cultural change might occur across higher education.     

Meztizaje and remembering in Afro-Mexican communities of the Costa Chica: implications for archival education in Mexico

This paper summarizes some of the major themes of a larger study that used Afro-Mexicans of the Costa Chica as a case study to understand archival education in Mexico. This study seeks to provide insight on how absences of Mexicans of African descent from the official record and recordkeeping came into being in Mexico; to examine the role that education of archival professionals might play in addressing or contributing to these absences; and to produce recommendations for remedying this under-documentation—at least in part—through changes to what is currently taught in formal archival education at the university level.     

Teaching Problem-Posing and Inquiry to Teachers Using a Non-Traditional Operation

Teaching teachers to participate in mathematical inquiry has the potential to both transform belief systems about mathematics and to transform teachers from consumers of mathematics to producers of mathematics. The focus of this paper is to describe the use of a problem, based on a non-traditional binary operation, to encourage and teach pre-service and in-service teachers inquiry and problem-posing. We present a brief mathematical solution for the problem and we then discuss problem-posing activities and discussions of connections to the Standards of Mathematical Practice from the Common Core State Standards. We discuss several key aspects of the problem that make it well-suited for the purposes of teaching inquiry and problem-posing.     

Systematic educational change and teacher skill-building in developed and developing countries: the importance of teacher peer learning groups

Many developed and developing countries are seeking to systematically transform their education processes through Information and Communication Technology (ICT). The aim of this paper is to present findings from one aspect of a larger ICT study in a particular location in a developing country, with the specific focus presented here being ICT professional development and impacts. Research methods in the study included teacher and school leader surveys, targeted interviews and also case studies. Findings at a systems level generally indicated insufficient coordination of training and minimal follow-up occurring. In case study situations in which the school leader ensured a schoolwide approach to the professional learning of teachers, ICT was more embedded into student learning processes in classrooms. Considering ICT and other professional learning relevant to education, this paper has relevance for policy developers and school leaders in developed and developing world contexts. The need exists for using coordinated professional development processes, with more centralised ‘one-off’ training supplemented by schools and districts. The establishment of peer learning groups or mentors to support skill-building over time is also needed. Through these ongoing processes, teachers can more effectively make changes in their teaching practices, with potential impacts on student learning.     

The Foodborne Outbreak Challenge—Using Experiential Learning to Foster Interdisciplinary Training Among Students on Foodborne Disease Outbreak Investigations

The Integrated Food Safety Centers of Excellence aim to develop novel learning methods to educate and train the future public health workforce to investigate foodborne outbreaks. The Foodborne Outbreak Challenge (FOC) was a one‐day event hosted by the Colorado Integrated Food Safety Center of Excellence at the Colorado School of Public Health. The FOC incorporated experiential, problem‐based, and interdisciplinary pedagogies from case studies, simulation exercises, and public health case competitions, to deliver a novel learning experience that met the training needs of a multidisciplinary foodborne outbreak response team with diverse skills sets. The event received positive feedback, and participants demonstrated knowledge gain. Event materials are available for other institutions to use.     

Optimization of Maximal Rate of Heart Rate Increase Assessment in Runners

Purpose: Correlations between fatigue-induced changes in exercise performance and maximal rate of heart rate (HR) increase (rHRI) may be affected by exercise intensity during assessment. This study evaluated the sensitivity of rHRI for tracking performance when assessed at varying exercise intensities. Method: Performance (time to complete a 5-km treadmill time-trial [5TTT]) and rHRI were assessed in 15 male runners following 1 week of light training, 2 weeks of heavy training (HT), and a 10-day taper (T). Maximal rate of HR increase (measured in bpm·s^?1) was the first derivative maximum of a sigmoidal curve fit to HR data recorded during 5 min of running at 8 km·h^?1 (rHRI_8km·h^?1), and during subsequent transition to 13 km·h^?1 (rHRI_{8–13km·h^?1}) for a further 5 min. Results: Time to complete a 5-km treadmill time-trial was likely slower following HT (effect size ± 90% confidence interval = 0.16 ± 0.06), and almost certainly faster following T (–0.34 ± 0.08). Maximal rate of HR increase during 5 min of running at 8 km·h^?1 and rHRI_{8–13km·h^?1} were unchanged following HT and likely increased following T (0.77 ± 0.45 and 0.66 ± 0.62, respectively). A moderate within-individual correlation was found between 5TTT and rHRI_8km·h^?1 (r value ± 90% confidence interval = –.35 ± .32). However, in a subgroup of athletes (n = 7) who were almost certainly slower to complete the 5TTT (4.22 ± 0.88), larger correlations were found between the 5TTT and rHRI_8km·h^?1 (r = –.84 ± .22) and rHRI_{8–13km·h^?1} (r = –.52 ± .41). Steady-state HR during rHRI assessment in this group was very likely greater than in the faster subgroup (≥ 1.34 ± 0.86). Conclusion(s): The 5TTT performance was tracked by both rHRI_8km·h^?1 and rHRI_{8–13km·h^?1}. Correlations between rHRI and performance were stronger in a subgroup of athletes who exhibited a slower 5TTT. Individualized workloads during rHRI assessment may be required to account for varying levels of physical conditioning.     

Reducing prolonged sedentary time using a treadmill desk acutely improves cardiometabolic risk markers in male and female adults

This study evaluated the acute effects of interrupting prolonged sitting with an accumulated 2 h of light-intensity walking on postprandial cardiometabolic risk markers. In this randomised crossover trial, 24 participants (twelve males) aged 18–55 years took part in two, 6.5 h conditions: 1) prolonged sitting (SIT) and 2) sitting interrupted hourly with 20 min light-intensity treadmill desk walking at between 1.2–3.5 km/h^?1 (INT-SIT). Standardized meals were provided at 0 h and 3 h. Blood samples and blood pressure measures were taken hourly. Statistical analyses were completed using linear mixed models. Postprandial incremental area under the curve responses (mmol/L?6.5 h) for glucose (4.52 [3.47, 5.56] and 6.66 [5.62, 7.71] for INT-SIT and SIT, respectively) and triglycerides (1.96 [0.96, 2.96] and 2.71 [1.70, 3.71] for INT-SIT and SIT, respectively) were significantly lower in INT-SIT than SIT. Mean systolic and diastolic blood pressure responses were lower by 3% and 4%, respectively, in INT-SIT than SIT (P < 0.05). There was no significant condition x sex interaction effect for any outcomes (P > 0.05). These findings suggest that interrupting sitting with an accumulated 2 h of light-intensity walking acutely improves cardiometabolic risk levels in males and females compared with prolonged sitting.
