Mental Health Provision in Northern Canada: Practitioners’ Views on Negotiations and Opportunities in Remote Practice

The focus of this article is on the final expanded qualitative findings and meta-analysis of a northern Canada study involving a four-phase, 3-year research design. The qualitative findings from interviews with twenty informal and formal mental health practitioners focus on the broader themes found within the meta-analysis in an attempt to answer a recent call for more proactive literature emphasizing opportunities for counselling and mental health support. The results explored included helping professional and paraprofessional development within remote settings, visions for the provision of community supports to assist them in providing services, and components of a conceptual model of mental health practice in the Canadian North.     

Exploring students’ competence,autonomy and relatedness in the flipped classroom pedagogical model

This study aimed at identifying the differences between a flipped classroom and a non-flipped classroom instructional model, based on the Self-Determination Theory (SDT). This study employed a mixed-method research approach, using post-tests, questionnaires and focus group interviews during the data collection process. Sixty-one students were the respondents involved in a non-randomised experiment with a control group design, while 10 representative students participated in a focus-group discussion. The results reported that post-test 1 showed no significant difference between the two groups of flipped and non-flipped classroom instruction (t = 1.68, p = .474), while post-tests 2 and 3 were significantly different (t = 5.54, p = .007 < .05) and (t = 10.17, p = .001 < .05). This finding shows that students in the flipped learning environment were more competent handling online tasks and activities, and were able to control their learning outcomes. The survey results showed that the flip-class setting fostered better peer interaction and autonomous learning skills among the students. The flip-class environment had also a positive influence on students’ intrinsic motivation. The qualitative findings from the students’ interviews revealed that students were motivated by the video-recorded lectures, self-regulated learning environments, engagement in class activities and peer interaction. Conclusions from this study showed that the flip-class setting had successfully established the basic psychological needs of SDT, namely: competency, autonomy and relatedness in a flipped classroom model.     

Can a Domain-General Spatial Intervention Facilitate Children’s Science Learning? A Lesson From Astronomy

Correlational studies link spatial-test scores and science, technology, engineering, and mathematics achievement. Here we asked whether children’s understanding of astronomical phenomena would benefit from a prior intervention targeting a core component of children’s projective spatial concepts—understanding that viewers’ visual experiences are affected by vantage point. Children (8–9 years; N = 66) received outdoor and indoor experiences that did (Experimental) or did not (Control) focus on how scene appearance is affected by viewers' positions and movements. All then received an astronomy lesson about celestial motions (e.g., Sun apparent motion). Experimental-group children scored higher on immediate and 1-week perspective-taking tests and explained celestial phenomena more accurately than did control-group children. Data demonstrate that general spatial training—divorced from specific science content—can aid children’s subsequent learning of scientific phenomena.     

Innovation and knowledge sharing across professional boundaries: Political interplay between boundary objects and brokers

The article examines the process of innovation and knowledge sharing from a perspective that focuses on the influence that local circumstances can have. In particular, it looks at the problems of knowledge sharing between groups of professionals. It presents a comparative analysis of two studies, one involving two groups of IT professionals; the other a network of healthcare professionals. The data was collected in two sets. The first set consisted of the results from two earlier, independent studies; the second was collected specifically for this article. We investigate the role played by boundary objects and brokers. Through an analysis of the interplay between boundary object and broker, we uncover the dynamics of the innovation process and show that the role played by the broker can be political. We identify two strategies that are used by brokers in the selection of a boundary object. The first is directed towards achieving a balance between the actors involved and the second is directed towards controlling their activities. We conclude by suggesting that other researchers should also consider the interplay between broker and boundary object when examining cross-boundary knowledge sharing.     

Effect of antioxidants and exercise on bone metabolism

We examined the effects of antioxidant supplementation in association with progressive aerobic training on the bone metabolism of healthy elderly individuals. For 8 weeks, 13 participants (mean age 74 years) received vitamin C (500 mg) and vitamin E (100 mg) daily and participated in a supervised progressive aerobic training programme. After the 8 weeks, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D concentrations were increased significantly by 42.8% (P < 0.001) and 26.8% (P < 0.01) respectively, while parathyroid hormone concentration was decreased by 17.5% (p < 0.05). Of the bone markers, only bone alkaline phosphatase decreased, by 14.6% (P < 0.05). No variation was observed for ionized calcium, insulin-like growth factor-1 or insulin-like growth factor binding protein-3. Our findings suggest that 8 weeks of combined antioxidant supplementation and aerobic training modified vitamin D metabolism and parathyroid hormone concentration. These adaptations might counterbalance the unfavourable hormonal profile frequently observed in the elderly that predisposes them to accentuated age-related bone loss.     

High-Active Children and Achievement Tests: A two-year follow-up

A two-year follow-up of 52 elementary school children indicated that in fourth grade, as in second grade, language ability, as measured by the WISC-R Vocabulary subtest, was more strongly related to Achievement Test scores among high-actives than among nonhigh-actives. High-active children of low-to-average language ability had significantly lower achievement test scores than nonhigh-actives, with significant decrement in scores in Reading subtest over the two-year period. On the other hand, high-actives of high language ability had scores only slightly lower than nonhigh-actives, with differences that did not reach significance. Discussion centers on implications for further research and for educational interventions for hyperactive children.
