Plasma ß‐endorphin immunoreactivity: Response to resistance exercise

Previous research investigating the response of plasma ß‐endorphins (ß‐EP) to resistance exercise has resulted in equivocal findings. To further examine the effects of resistance exercise on ß‐endorphin immunoreactivity, six resistance‐trained athletes participated in a three‐set series of eight repetitions of isotonic exercise. All exercises were performed at 80% maximal effort. Blood was sampled from the group by venepuncture, both prior to and following the exercise bout, and ß‐endorphin concentration was determined by radioimmunoassay. The results indicated that mean ( ± S.E.) plasma levels of ß‐endorphins following exercise (18.04 ± 3.4 pg ß‐EP ml^‐1) were not significantly changed from pre‐exercise (control) levels (19.59 ± 2.4 pg ß‐EP ml^‐1), although there was considerable inter‐individual variability. Our results support previous research which has reported no significant changes in ß‐endorphin immunoreactivity following resistance exercise, as well as reported findings of considerable variability in the ß‐endorphin response to exercise.     

A labour of love: mothers,emotional capital and homework

This paper develops a new analysis of homework by building on feminist scholarship which documents the invisible labour done by women in support of their children's education. While numerous studies have examined the relationship between homework and achievement, little attention has been paid to the largely gendered and potentially stressful nature of ‘parental involvement’. The analytic focus in this paper is on the complex emotional and pedagogical dimensions of homework and the ways it is shaped by socio-cultural contexts. Videotaped homework interactions between one working-class and two middle-class mothers and their children are examined using Bourdieu's concepts of habitus and capital. The analysis distinguishes between productive pedagogical relationships and those that promote extensive anxiety and are counterproductive to learning. The paper argues that the reserves of cultural and emotional capital required for homework completion are significant and that class position does not necessarily guarantee the ways in which these capitals are mobilised.     

Students' Knowledge About Environmental Matters and Their Belief in Their Own Action Possibilities–A Danish Study

Abstract

Drawing chiefly from Paul Shepard's (1982) Nature and Madness and David Abram's (1996) The Spell of the Sensuous, this essay draws attention to two underlying foundations of educational thought: the process of human social development and the emergence of language and literacy. A reading of Shepard and Abram implies that the meaning of human social development and the meaning of literacy must be recovered from our shared human heritage in which human beings developed a sense of interconnection with nonhuman others. This perspective suggests many challenges to environmental educators including (a) the need to take a more philosophical (and less instrumental) approach to our work, (b) the need for a working theory of development and literacy in education that takes nonhuman otherness seriously, (c) the need to advocate for more regular and extended experiences in the natural world in order to nurture relationship with otherness, (d) the need to reinvent “accountability” in education, (e) and the need to develop in all learners, including ourselves, a sense of at-homeness.     

Assisting self-explanation prompts are more effective than open prompts when learning with multiple representations

Learning with multiple representations is usually employed in order to foster understanding. However, it also imposes high demands on the learners and often does not lead to the expected results, especially because the learners do not integrate the different representations. Thus, it is necessary to support the learners’ self-explanation activity, which concerns the integration and understanding of multiple representations. In the present experiment, we employed multi-representational worked-out examples and tested the effects of two types of self-explanation prompts as help procedures for integrating and understanding multiple representations. The participants (N = 62) learned about probability theory under three conditions: (a) open self-explanation prompts, (b) self-explanation prompts in an assistance-giving-assistance-withholding procedure (assisting self-explanation prompts), or (c) no prompts (control group). Both types of self-explanation prompts fostered procedural knowledge. This effect was mediated by self-explanations directed to domain principles. Conceptual knowledge was particularly fostered by assisting self-explanation prompts which was mediated by self-explanations on the rationale of a principle. Thus, for enhancing high-quality self-explanations and both procedural knowledge and conceptual understanding, we conclude that assisting self-explanation prompts should be provided. We call this the assisting self-explanation prompt effect which refers to the elicitation of high-quality self-explanations and the acquisition of deep understanding.     

When in Doubt,Go to the Library: The Effect of a Library-Intensive Freshman Research and Writing Seminar on Academic Success

The paper is an extension of a previous study, which examined student perceptions of a unique freshman seminar offered to Criminology and Criminal Justice students at Florida State University. The seminar is characterized by a heavy focus on interactive library sessions in which students learn how to conduct research and write a scholarly paper. The previous article reported on student perceptions of research and writing skills developed in the seminar. This report, using Multivariate Regression and Propensity Score Matching reveals that compared to a carefully constructed comparison group, first time in college students enrolled in the seminar have statistically significantly higher cumulative grade point averages and percentages of graduation within four years. The seminar’s emphasis on the library as a research tool is thought to have contributed to the differences seen on academic outcomes between students who took the seminar and a matched comparison group.     

Prompting undergraduate students’ metacognition of learning: implementing ‘meta-learning’ assessment tasks in the biomedical sciences

To succeed at post-secondary education, it’s essential that students develop an understanding of their own knowledge and learning processes. This metacognition of learning, or ‘meta-learning’, helps students to become more effective learners, as they become more aware of their self-regulatory processes and recognise the effectiveness of their study strategies. To increase biomedical science students’ self-awareness, we have designed and implemented meta-learning assessment tasks across our biomedical science courses. Most students reported that meta-learning tasks had a positive impact on their learning, as they prompted self-regulatory processes of forethought and self-reflection. We found that students were equally likely to change or not change their study strategies across subsequent semesters. Those students that did not change were generally high achievers, believing their study approaches were most effective, but their performance did not improve across semesters. In contrast, students who adapted, mostly by modifying how they appraised and rearranged records or improved planning and time management, performed less well overall but significantly improved their performance across semesters. Meta-learning tasks may prompt students to become more self-reflective and independent learners by affecting their approach to learning, enabling them to reflect on their study strategies, adapt and improve performance, and may enable the development of lifelong learning skills.     

Polymorphisms within the COL5A1 gene and regulators of the extracellular matrix modify the risk of Achilles tendon pathology in a British case-control study

Several genetic loci have been associated with risk of Achilles tendon pathology (ATP) within South African and Australian populations. The aim of this study was, therefore, to evaluate eight previously implicated genetic variants in an independent British population. A total of 130 asymptomatic controls (CON) and 112 participants clinically diagnosed with ATP comprising 87 individuals with chronic Achilles tendinopathy (TEN) and 25 with Achilles tendon ruptures (RUP) were included. All participants were genotyped for variants within the COL5A1, MIR608, IL-1β, IL-6 and CASP8 genes. Primary findings implicated COL5A1 and CASP8. Three inferred allele combinations constructed from COL5A1 rs12722, rs3196378 and rs71746744 were identified as risk modifiers. The T–C–D combination was associated with increased risk of ATP (P = 0.023) and RUP (P < 0.001), the C–A–I combination was associated with increased risk of ATP (P = 0.011), TEN (P = 0.011) and RUP (P = 0.011) and the C–C–D combination was associated with decreased risk of ATP (P = 0.011) and RUP (P = 0.004). The CASP8 rs3834129 DD genotype was associated with decreased risk of TEN (P = 0.020, odds ratio: 0.45, 95% confidence interval: 0.22–0.90) and the CASP8 I–G (rs3834129–rs1045485) inferred allele combination was associated with increased risk of TEN (P = 0.031). This study further highlights the importance of polymorphisms within COL5A1 and CASP8 in the aetiology of ATP.     

A Systematic Review of Life Skill Development Through Sports Programs Serving Socially Vulnerable Youth

Purpose: Despite the strong belief in sports programs as a setting in which socially vulnerable youth can develop life skills, no overview exists of life skill development in sports programs serving this youth group. Therefore, the present systematic review provides an overview of the evidence on life skill development in sports programs serving socially vulnerable youth and, insofar as it was investigated in the included studies, of the conditions conducive to life skill development in these sports programs. Method: Potentially relevant studies published during 1990 to 2014 were identified by a search in 7 electronic databases. The search combined terms relating to (a) sport, (b) youth AND socially vulnerable, and (c) life skills. Eighteen of the 2,076 unique studies met the inclusion criteria. Results: Each included study reported that at least 1 life skill improved in youth who participated in the studied sports program. Improvements in cognitive and social life skills were more frequently reported than were improvements in emotional life skills. Only a few of the included studies investigated the conditions in the studied sports programs that made these programs conducive to life skill development. Conclusions: Sports programs have the potential to make a difference in the life skill development of socially vulnerable youth. This conclusion needs to be treated with some caution, because the studies experienced many challenges in reducing the risk for bias. Several alternative research strategies are suggested for future studies in this field.
