Resting MAPK expression in chronically trained endurance runners

Purpose: There is a paucity of research investigating the expression of mitogen-activated protein kinases (MAPK) in chronically trained (CT) athletes. Thus, it is unclear how MAPK may contribute to performance and muscle adaptation in CT subjects. The purpose of this study was to determine MAPK total protein, and phosphorylated expression of extracellular signal-regulated kinases 1 and 2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38-MAPK (p38) between untrained, and chronically trained runners. Methods: Tissue samples were analysed from sedentary (SED; n?=?5) controls and chronically trained runners (CT; n?=?5). Resting muscle biopsy samples were analysed for total-MAPK – and ratio of phosphorylated/total (p-MAPK) – ERK1/2, JNK, and p38-MAPK via western blotting. Mann–Whitney U tests and effect sizes were utilized to determine differences in total MAPK protein content and phosphorylation status between SED and CT subjects. Results: There was no difference in total-MAPK expression between SED and CT (p?>?.05). p-p38-MAPK tended to be greater for CT compared to SED (p?=?.07). There were moderate effect sizes of decreased pERK/total-ERK (d?=??0.69) and increased pJNK/total-JNK (d?=?0.54) in CT compared to SED. There was a positive correlation between p-p38-MAPK/total-MAPK and the percentage of type I fibres (r?=?0.73, p?=?.016). Conclusion: Contrary to previous studies, chronic endurance training does not greatly influence total MAPK protein expression in chronically trained runners. However, resting phosphorylation of p38-MAPK may contribute to enhanced oxidative metabolism at chronically trained levels. These alterations are likely involved in the different physiological adaptations that occur following long-term training or at highly competitive levels.     

Psychodrama and sociodrama in primary and secondary education

Students need practice in decision making and problem solving, and sociodrama can provide this practice in a safe, nonthreatening context. It helps them to become aware of the typical ways they solve problems, and it increases both social and personal awareness. It may promote acceptance, cooperation, and cohesiveness in the classroom. Students readily adapt to this kind of activity and find it both enjoyable and stimulating. It is recommended as a useful method in the classroom and guidance and counseling setting for helping students understand their own behavior and the behavior of others.     

Computer support in a rural setting: A comparison of computer-assisted and handwritten evaluation reports

The present blind study compared the quality of psychoeducational reports generated under two conditions. On the average, reports written with computer assistance were rated to be of higher quality than those prepared by hand. Also presented are data validating the large expenditure of staff time on report preparation, along with estimates of the time saving that may be realized with computer assistance. The relevance of computer support to relatively isolated, rural-based clinical staff is discussed.     

Managing Reform: Lessons from Urban High Schools

ABSTRACT

American high schools present an extremely difficult, nearly intractable setting for serious educational reform efforts. Yet such efforts can succeed. This article reports results from a survey of 179 urban comprehensive high schools that were successfully implementing change programs based on effective schools principles.

All schools encountered problems of implementation. Larger‐scale, instructionally‐oriented, and longer‐lasting programs induced more problems. Problems were only moderated, not eliminated, by good‐quality planning.

Given the problem‐richness of change efforts, the major determinant of successful implementation was good problem‐coping. It was made more likely by the presence of consensus (shared vision), support of key stakeholders in and out of the school, planning quality, external assistance, and administrative time spent. Case studies showed that the presence of an empowered change management group aided all these critical factors.

Schools with the most impact (defined as student outcomes, teacher improvement, and organizational improvement) had focused on teacher or organizational changes to begin with, coped with the inevitable problems well, had internal and external constituencies supporting the change effort, and sustained the work for a longer period of time (typically 4‐5 years).

The key variables appear to form a coherent causal network. Implications for change management are drawn.     

Writing for Social Scientists: How to Start and Finish Tour Thesis,Book, or Article.

Underlined by the belief that teachers' critical awareness of their actions is a vital issue in education, this study examines the insights that evolved from a long-term collaboration among seven doctoral students. To prepare for our comprehensive examinations, we collaborated as a study group for one and one-half years. Adopting the dual roles of listener-researcher and narrator-participant, we engaged in dialogue and narrative to convey to each other the meaning of our collaborative experiences. From grounded theory analysis, four elements of collaboration emerged: logistics, social dynamics, empowerment, and change. In order to convey the meaning of our experiences, we create a multiplicity of meanings based on our diverse and lived personal narratives. Finally, our collaborative process challenges academic administrations to examine how well their current policies encourage personal autonomy and cooperative learning approaches for students involved in preparing for their comprehensive examinations.     

Using Cognitive Load to Evaluate Participation and Design of an Asynchronous Course

Abstract

This study examined the effects of cognitive load experienced by e-learners as they negotiated the tasks required for successful participation within an asynchronous course room, specifically examining the relationship between measured cognitive load and the learners' confidence in completing their course. The results indicated that learner confidence, or more specifically self-efficacy, is the single most important factor in determining the success of e-learners. It appears that insufficient time was expended orienting learners to the virtual classrooms and to the technology necessary for participation.
