Effects of 12 weeks of combined training without caloric restriction on inflammatory markers in overweight girls

The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13–17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6–10 repetitions at 60–70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50–80% VO_2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO_2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO_2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls.

Relations of Children's Effortful Control and Teacher-Child Relationship Quality to School Attitudes in a Low-Income Sample

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children.     

Emergent Supervisors: Comparing Counseling Center and Non‐Counseling‐Center Interns' Supervisory Training Experiences

Predoctoral interns' responses to an internship supervision training questionnaire indicated that counseling center interns supervised more trainees, received more supervision in their supervisory roles, reported more supervision training activities, and yielded higher supervisor development scores than did non‐counseling‐center interns. A qualitative analysis of participants' responses showed that non‐counseling‐center interns desired more supervision training and opportunities to provide supervision during their internship year than did counseling center interns.     

Children’s Memory: A Primer for Understanding Behavior

This paper provides the opportunity to understand children’s behavior from a memory viewpoint. For the last three decades, cognitive developmentalists have been asking the question, “what develops in children’s memory?” Four answers to this question are presented, complete with explanations, examples, and possible applications where appropriate. The purpose of the paper is to provide early childhood educators and other practitioners who work with children a different lens through which to view children’s behavior. The memory view is compatible with current best practices in early childhood education, and may provide practitioners an additional viewpoint from which to draw when implementing developmentally appropriate practice.     

Metaphors we’re colonised by? The case of data-driven educational technologies in Brazil

ABSTRACT

This article discusses issues concerning the spread of data-driven educational technologies in Brazil. Here, as elsewhere, educational technology continues to be promoted optimistically as the bearer of a panacea for historically-rooted social problems. Whilst some of these technologies have indeed contributed to important widening-participation programmes in the last two decades, widespread advocacy of technological ‘solutionism’, reflected in gradually stronger policy demands for efficiencies to be improved through ‘innovation’, has supported a relentless marketisation of the country’s educational systems. As transnational corporations position themselves to take control of key areas of these systems, threatening to restructure the whole sector, data-driven educational technologies provide the latest example in a series of ‘new’ ideas offered in an ever-expanding market. Based on the notion of ‘conceptual metaphors’, which encapsulate specific ways of perceiving, thinking and relating with the world, this article examines key metaphors underpinning discourses surrounding data-driven educational technologies in Brazil. In particular, the article analyses ways in which these specific metaphors may be promoting perspectives that ignore difference and obscure broader questions concerning education, thus contributing to the reproduction of previously existing problems and supporting new forms of colonisation.     

伊朗伊拉克关系研究(1979-1991)

在过去40余年中，伊朗和伊拉克两国关系错综复杂，特别是在伊朗1979年革命以后，由于教派分歧、地区领导权争夺、领土纠纷等因素，两伊冲突呈加剧趋势，并且最终导致爆发两伊战争。海湾战争使两伊关系有所改善，但好景不长。随着冷战结束和地区形势变化，两国的国际处境越发困难，国内问题也层出不穷，因此在经历了革命与战争的磨难后，两国关系渐趋解冻并获绳一些发展，但前景仍不容乐观。
