Mediation role of cardiorespiratory fitness on the association between fatness and cardiometabolic risk in European adolescents: The HELENA study

PurposeThis study was aimed to analyze the mediation role of cardiorespiratory fitness (CRF) on the association between fatness and cardiometabolic risk scores (CMRs) in European adolescents.MethodsA cross-sectional study was conducted in adolescents (n = 525; 46% boys; 14.1 ± 1.1 years old, mean ± SD) from 10 European cities involved in the Healthy Lifestyle in Europe by Nutrition in Adolescence study. CRF was measured by means of the shuttle run test, while fatness measures included body mass index (BMI), waist to height ratio, and fat mass index estimated from skinfold thicknesses. A clustered CMRs was computed by summing the standardized values of homeostasis model assessment, systolic blood pressure, triglycerides, total cholesterol/high-density lipoprotein cholesterol ratio, and leptin.ResultsLinear regression models indicated that CRF acted as an important and partial mediator in the association between fatness and CMRs in 12–17-year-old adolescents (for BMI: coefficients of the indirect role β = 0.058 (95% confidence interval (95%CI): 0.023–0.101), Sobel test z = 3.11 (10.0% mediation); for waist to height ratio: β = 4.279 (95%CI: 2.242–7.059), z =3.86 (11.5% mediation); and for fat mass index: β = 0.060 (95%CI: 0.020–0.106), z = 2.85 (9.4% mediation); all p < 0.01).ConclusionIn adolescents, the association between fatness and CMRs could be partially decreased with improvements to fitness levels; therefore, CRF contribution both in the clinical field and public health could be important to consider and promote in adolescents independently of their fatness levels.     

COLLEGE IMPACT ON STUDENT LEARNING: Comparing the Use of Self-Reported Gains,Standardized Test Scores,and College Grades

To examine the impact of college researchershave used a variety of measures of learning and fairlycomparable results have been obtained. This studyundertakes a direct comparison of three learningindicators: college grade-point average, student reportedgrowth (Verbal and Quantitative), and GRE scores(Verbal, Quantitative, and Composite). The same set ofindependent variables was regressed onto each dependent measure using a national sample of 2,289students. Substantive interpretations are presented andcomparisons are made for paired regressions usingalternate indicators. This paper provides evidencesuggesting that (1) student-reported cognitive growthsurvey items have a modest relative validity; (2) theattenuation associated with the use of residual gainscores does not invalidate their use; and (3) comparable results are obtained when using the college GPAand standardized test scores. It is concluded that thealternate measures can be used as proxies for moredirect measures of learning.     

Black women’s bodies,ideology, and the public curriculum of the pro- and anti-choice movements in the US

This paper explores how opposite sides of the abortion debate employ a discourse of endangerment to mobilise political support for their ideologies about black women’s bodies. I examine the role of black women within that rhetorical strategy through various rhetorical artefacts. To analyse these artefacts, I employ the theoretical framework of ideological or ideographic criticism. This framework helps us see how the artefacts used by both pro and anti-choice movements ‘condition’ the audience not merely to adopt a set of ‘beliefs and behavior, but a vocabulary of concepts that function as guides, warrants, reasons, or excuses for behavior and belief’. Though the two sides of the abortion debate differ in their overt political views, they turn out to share an implicit ideology about black women. This ideology prevents the voices of black women from being heard and valued in a debate that is nonetheless focused on black women’s bodies.     

Measuring the continuum of literacy skills among adults: educational testing and the LAMP experience

The field of educational testing has become increasingly important for providing different stakeholders and decision-makers with information. This paper discusses basic standards for methodological approaches used in measuring literacy skills among adults. The authors address the increasing interest in skills measurement, the discourses on how this should be done with scientific integrity and UNESCO??s experience regarding the Literacy Assessment and Monitoring Programme (LAMP). The increase in interest is due to the evolving notion of literacy as a continuum. Its recognition in surveys and data collection is ensured in the first commitment in section?11 of the Bel??m Framework for Action. The discourse on how measurements should be carried out concerns the need to find valid parsimonious approaches, also their relevance in different institutional, cultural and linguistic contexts as well as issues of ownership and sustainability. Finally, UNESCO??s experience with LAMP shows how important addressing these different issues is in order to equip countries with an approach that is fit for purpose.     

Exploring Knowing/Being Through Discordant Professional Practice

Despite an increasing array of ‘quality indicators’ and substantial investments in educating professionals, there continues to be clear evidence of discordant, or even negligent, practice by accredited professionals. We refer to discordant professional practice as being ‘out of tune’ with what is accepted as good practice. In a conceptual/theoretical analysis, we use discordant practice as a backdrop to exploring ways of being professionals. Our analysis is grounded in Heidegger’s notion of being-in-the-world. We explore how being-in-the-world can be uncanny and discordant, while at the same time, dwelling in the world implies familiarity and a sense of being ‘at home’. We also draw upon Merleau-Ponty’s arguments that know-how is performed, settling in the body to become habitual, while also incorporating others and things in the accomplishment of practice. We argue that conceiving know-how as knowing/being provides insights into what is entailed in learning to be professionals.     

Standardisation and diversity in international assessments: barking up the wrong tree?

ABSTRACT

This article organises potential areas of criticism or challenges embedded in the design and administration of standardised assessments of learning levels in order to promote dialogue and research on educational assessments. The article begins by addressing debates around epistemological claims: issues that pertain to testing in general and issues that are particular to standardised testing. Then, it addresses some political attributes of international tests so as to situate the debates beyond feasibility, attributes and scope-related issues. The article claims that the field of education testing has identified a number of issues and challenges stemming from diversity, and has developed methods and procedures to address many of them. From this viewpoint, testing is just like any other domain of scientific enquiry. However, international assessments of learning outcomes are not necessarily, or primarily, scientific endeavours; they are political devices and therefore should be scrutinised considering scientific attributes as well as some political features that, even if intertwined with technicalities, go well beyond them. Thus, critiques of international assessments would be better framed if their political attributes are taken as organising principles of the criticism, alongside those elements that pertain to their technical attributes, since these are not incidental but deeply interlinked.     

Success at Scale: Outcomes of Community-Based Neurodevelopment Intervention (CASITA) for Children Ages 6–20 months With Risk of Delay in Lima,Peru

This study is a randomized controlled trial of a 12-week community-based group parenting intervention (“CASITA”) in Lima, Peru. CASITA improved neurodevelopment in a pilot study of 60 Peruvian children and subsequently scaled to 3,000 households throughout the district. The objective of this study was to assess intervention effectiveness when implemented at scale. A total of 347 children ages 6–20 months (52.7% male, 100% identified as “mestizo”) at risk for developmental difficulties were randomized to immediate or delayed CASITA. At 3 months after enrollment, the immediate arm showed significantly higher overall development, based on the Extended Ages and Stages Questionnaire and Home Observation for Measurement of the Environment scores (Cohen’s ds = .36 and .31, respectively). Programs demonstrably effective at scale could help address children’s development risks worldwide.     

Educating Teachers to Teach Multiplicative Structures in the Middle Grades

The middle-grades mathematics related to multiplicative structures has undergone careful scrutiny over the past decade. Researchers have identified the types of reasonings involved; the difficulties students have with the concepts and why these difficulties might occur; and the interconnections within this content area. On the basis of this research we make four recommendations for the preparation and professional development of teachers. The recommendations deal with different but related forms of reasoning: quantitative reasoning, multiplicative reasoning, proportional reasoning, and reasoning with rational numbers. Problematic issues that follow from the recommendations are discussed. This revised version was published online in July 2006 with corrections to the Cover Date.     

Effects of a nonlinear pedagogy intervention programme on the emergent tactical behaviours of youth footballers

Purpose: This study analysed the effects of a training intervention programme using principles of Non-Linear Pedagogy (NLP) on the decision making (DM) and performance behaviours (P) of youth footballers.

Method: 19 footballers (U12 yrs) participated in 14 training sessions, spread over three phases: Pre-intervention, Intervention, Retention. The intervention was based on Small-Sided and Conditioned Games. We assessed progress during the intervention phase at two different points: intermediate and final. The GPET instrument was used to analyse the DM and P during the completion of 3208 passes in the intervention.

Results: Results shown significant improvements in the DM and P after the intermediate and final points of the acquisition phase. Moreover, significantly higher values were also obtained in both variables in the retention, compared to the pre-intervention phase.

Conclusion: Results indicated that the NLP intervention programme was effective in improving both aspects of team games performance in youth players, with effects consolidated over time.
