Neoliberalism, capitalist ideas, and the disastrous human-induced state of the environment are evidence of the lack of connection between humans and the earth, calling for a rethinking of the relationships between humans and the planet. As early childhood educators, we wonder about our role in rethinking these relationships and in particular, the relationship between children and planet. In this article, we articulate the actions and positioning of teachers in three different research studies and various contexts (Victoria, AUS; Oregon, USA; California, USA) utilizing Latour’s (2004) ‘matters of concern’ as a framework to rethink engagement and relationality. Each project considers how place can be a provocation that makes visible the entanglement of children, families, teachers, and the more-than-human as a way to rethink pedagogy. The limitations, tensions, and possibilities that occur within and across these entanglements are explored, highlighting how the enacted practices could disrupt dominant early childhood discourses and practices. 相似文献

Based on Nonaka’s knowledge spiral, this paper examines how processes of knowledge creation contribute to success in academia.
It presents the outcomes of an in-depth exploration of the workings of the knowledge spiral in a university research institute.
The research shows the outstanding but undervalued importance of socialization processes. It also shows that, while research
success is typically defined at the interplay of the individual, group and institutional levels, in the institute that was
examined none of the four knowledge creation processes (socialization, externalization, combination and internalization) appears
to run smoothly at the institutional level. 相似文献

The aim was to develop, implement, and evaluate a physical education-based coping training program for vocational students. Two vocational schools participated in the quasi-experimental pilot study (EPHECT I). One school received the intervention (intervention group: n?=?434), while the other school maintained regular physical education classes (control group: n?=?430). Repeated measures ANCOVAs were used to examine the effects on coping and perceived stress. Additionally, effects were compared among students who reported low versus elevated life satisfaction. Finally, the implementation rate was considered as a moderating factor. Overall, no significant time by group effects were found between the intervention group and the control group. However, a reduction in maladaptive coping occurred among students of the intervention group who reported low life satisfaction. The implementation rate did not moderate the findings. Despite a relatively low implementation rate, the intervention program reduced maladaptive coping strategies in adolescents with low life satisfaction. Program monitoring needs to be increased in future research. 相似文献

The purpose of this study was to investigate whether using different focus affects electromyographic (EMG) amplitude and contraction duration during bench press performed at explosive and controlled speeds. Eighteen young male individuals were familiarized with the procedure and performed the one-maximum repetition (1RM) test in the first session. In the second session, participants performed the bench press exercise at 50% of the 1RM with 3 different attentional focuses (regular focus on moving the load vs contracting the pectoralis vs contracting the triceps) at 2 speed conditions (controlled vs maximal speed). During the controlled speed condition, focusing on using either the pectoralis or the triceps muscles increased pectoralis normalized EMG (nEMG) by 6% (95% CI 3–8%; p = 0.0001) and 4% nEMG (95% CI 1–7%; p = 0.0096), respectively, compared with the regular focus condition. Triceps activity was increased by 4% nEMG (95% CI 0–7%; p = 0.0308) at the controlled speed condition during the triceps focus. During the explosive speed condition, the use of different focuses had no effect. The different attentional focus resulted in comparable contraction duration for the measured muscles when the exercise was performed explosively. Using internal focus to increase EMG amplitude seems to function only during conditions of controlled speed. 相似文献

A better understanding of what motivates humans to perform certain actions is relevant for a range of research challenges including generating action sequences that implement goals (planning). A first step in this direction is the task of acquiring knowledge about human goals. In this work, we investigate whether Search Query Logs are a viable source for extracting expressions of human goals. For this purpose, we devise an algorithm that automatically identifies queries containing explicit goals such as find home to rent in Florida. Evaluation results of our algorithm achieve useful precision/recall values. We apply the classification algorithm to two large Search Query Logs, recorded by AOL and Microsoft Research in 2006, and obtain a set of ∼110,000 queries containing explicit goals. To study the nature of human goals in Search Query Logs, we conduct qualitative, quantitative and comparative analyses. Our findings suggest that Search Query Logs (i) represent a viable source for extracting human goals, (ii) contain a great variety of human goals and (iii) contain human goals that can be employed to complement existing commonsense knowledge bases. Finally, we illustrate the potential of goal knowledge for addressing following application scenario: to refine and extend commonsense knowledge with human goals from Search Query Logs. This work is relevant for (i) knowledge engineers interested in acquiring human goals from textual corpora and constructing knowledge bases of human goals (ii) researchers interested in studying characteristics of human goals in Search Query Logs. 相似文献

Background: Although most adolescents successfully manage the transition between childhood and adulthood, the speed and magnitude of these changes may exceed the coping abilities of a significant number of young people. For vocational students, additional responsibilities arise during the vocational school transition and the need to balance academic and job-related requirements. An expanding body of literature suggests that adolescence is a vulnerable period for the development of psychiatric diseases and as such, the need to develop an adequate coping repertoire is receiving increasing attention globally. The growing awareness of long-term consequences of stress has led governments to instill school-based resilience promotion programs. For instance, the new physical education (PE) curriculum of vocational (vocational education and training (VET)) students in Switzerland addresses stress management, because stress-related diseases at the workplace have become commonplace among young professionals.Purpose: Our aim was to develop, implement and evaluate a PE-based coping training (EPHECT) for VET students. Therefore, we adapted components of extant field-tested coping training programs and tailored them to the unique needs of VET students. To facilitate the standardization of the program, each teacher received a teaching manual. Moreover, drawing upon experiential learning theory, we introduced the contents of the coping training in PE class through practical, movement-based exercises in PE. Students also received a workbook for use at home.Participants and research design: In this cluster randomized controlled trial, eight classes from a Swiss vocational school participated (N?=?131, Mage?=?16.22?±?1.12, 35% females). Two trained PE teachers implemented the program with students in the intervention group (IG?=?67) for three months, while students in the other four classes maintained regular PE (CG?=?64) to comprise the control group. To evaluate the coping training, all participants completed several self-report psychological questionnaires (assessing stress, coping and sleep) at baseline and follow-up. IG students completed further questions with regard to intervention fidelity at follow-up.Data analysis: To evaluate possible effects of the coping training on stress, coping and sleep, a 2?×?2 repeated-measures analysis of variance design was executed with time (pre vs. post) and group (IG vs. CG) as within- and between-subject factors.Findings: Over time, IG students significantly increased their adaptive coping compared to CG students, while stress and sleep remained relatively stable for both. Regularly completing one’s homework reinforced this effect because it was significantly associated with students’ reflection and compliance.Conclusion: A complete and accurate implementation of a PE-based coping training can make a positive contribution to the development of adaptive coping skills among adolescents attending vocational schools. This PE-based program allows students to experience their responses to stress directly and offers opportunities to experiment with different coping strategies. Adaptive coping skills are vital for successful stress management and the prevention of stress-related disorders across the work domain and in everyday life. 相似文献

Groin injuries are common in soccer and often cause time-loss from training. While groin injuries have been linked to full effort kicking, the role of inside passing is unclear. Therefore, the purpose of this study was to investigate hip joint kinematics and muscle force, stress and contraction velocity for adductor longus and gracilis during inside passing. 3D kinematics of ten soccer players (23.4 yrs; 77.5 kg; 1.81 m) were captured with a motion capture system inside a Footbonaut. Muscle force and contraction velocity were determined with AnyBody Modelling System. Gracilis muscle forces were 9% lower compared to adductor longus (p = 0.005), but muscle stress was 183% higher in gracilis (p = 0.005). Contraction velocity reveals eccentric contraction of gracilis in the last quarter of the swing phase. Considering the combination of eccentric contraction, high muscle stress and the repetitive nature of inside passing, gracilis accumulates high loads in matches and training. These results indicate that the high incidence of groin injuries in soccer could be linked to isolated pass training. Practitioners need to be aware of the risk and refrain from sudden increases in the amount of pass training. This gives the musculoskeletal system time to adapt and might avoid career threatening injuries. 相似文献
