Scales of political action and social movements in education: the case of the Brazilian Black Movement and Law 10.639

This paper examines social coordination by the Brazilian Black Movement in the area of Brazilian education. It explains how these developments relate to the construction of race-based public education policies in the country. Focus goes to the process of creation and implementation of law 10.639 in Brazilian Basic education. Using the concept ‘diffuse governance’, the argument is made that at present it are the multiple actions by the Brazilian Black Movement, in diverse arenas of dispute, and interacting with a range of actors, that enable us to understand the social coordination/regulation in the process of constructing and implementing Law 10.639.     

Drug Testing,Sex Verification,and the 1967 Pan-American Games

Abstract

Despite frequent claims that invasive methods of sex verification and early procedures for doping detection were used in 1966 and 1967 at different major international sport competitions, little is known about the origins and rationales for implementing such procedures. This paper focuses on the drug testing and sex verification protocols implemented at the 1967 Pan-American Games held in Winnipeg. Specifically, it explores the conditions that led to these protocols, as well as the details of and the arguments invoked for their implementation. To do so, archival material, media coverage featured in English, French, Portuguese, and Spanish newspapers and magazines across the Americas, and oral histories are analyzed and discussed. The paper demonstrates that neither the sex verification nor the drug testing protocol was mandatory for all athletes and only two very specific groups of athletes were targeted. It also demonstrates that in the case of the former, exceptions were made within the specific group targeted. The paper concludes that the rudimentary protocols applied at the 1967 Pan-American Games likely informed the IOC Medical Commission’s doping and sex-testing policies implemented at the 1968 Mexico City Olympics and Grenoble Winter Olympics.     

American influencies in Brazilian physical education: clues in the specialised periodical press (1932–1950)

This study investigates the American presence and influences in the physical education press to understand the way in which that presence influenced and contributed to the production of a sports culture in the first half of the twentieth century. As historical sources, the study uses periodicals in the field that were published in the period 1932–1950. As a theoretical frame of reference, it uses the repertoire of the New Cultural History in terms of strategy, tactics and devices. It is written in a narrative way, following Ginzburg's style, presenting data and contextualizing them with the historic scene. Clues enabled us to infer that the American presence, which was catalysed by the Brazilian Young Men's Christian Association (YMCA), sought to shape a sports culture from physical education and society. This effort reflected the yearning of Brazilian intellectuals for modernisation and an attempt at cultural colonisation by the government of the USA.

Leucine metabolites do not attenuate training-induced inflammation in young resistance trained men

ABSTRACT

Leucine metabolites may reduce training-induced inflammation; however, there is scant evidence for this assertion. We conducted a double-blind randomized controlled pragmatic trial where 40 male participants were allocated into 4 groups: α-hydroxyisocaproic acid group ([α-HICA], n = 10, Fat-free mass [FFM] = 62.0 ± 7.1 kg), β-hydroxy-β-methylbutyrate free acid group ([HMB-FA], n = 11, FFM = 62.7 ± 10.5 kg), calcium β-hydroxy-β-methylbutyrate group ([HMB-Ca], n = 9, FFM = 65.6 ± 10.1 kg) or placebo group ([PLA]; n = 10, FFM = 64.2 ± 5.7 kg). An 8-week whole-body resistance training routine (3 training sessions per week) was employed to induce gains in skeletal-muscle thickness. Skeletal muscle thickness (MT), one repetition maximum (1RM), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP) and tumour necrosis factor alpha (TNF-α) were assessed at baseline and at the end of weeks 4 and 8. Time-dependent increases were detected from baseline to week 8 for MT (vastus lateralis: p = 0.009; rectus femoris: p = 0.018), 1RM (back squat: α-HICA, 18.5% ± 18.9%; HMB-FA, 23.2% ± 16%; HMB-Ca, 10.5% ± 13.8%; PLA, 19.7% ± 9% and bench press: α-HICA, 13.8% ± 19.1%; HMB-FA, 15.5% ± 9.3%; HMB-Ca, 10% ± 10.4%; PLA, 14.4 ± 11.3%, both p < 0.001), IL-6, hsCRP (both p < 0.001) and TNF-α (p = 0.045). No differences were found between groups at any time point. No leucine metabolite attenuated inflammation during training. Additionally, backwards elimination regressions showed that no circulating inflammatory marker consistently shared variance with the change in any outcome. Using leucine metabolites to modulate inflammation cannot be recommended from the results obtained herein. Furthermore, increases in inflammatory markers, from training, do not correlate with any outcome variable and are likely the result of training adaptations.     

Factor structure of child behavior scale scores in peruvian preschoolers

Behavior rating scales aid in the identification of problem behaviors, as well as the development of interventions to reduce such behavior. Although scores on many behavior rating scales have been validated in the United States, there have been few such studies in other cultural contexts. In this study, the structural validity of scores on a Spanish translation of the six‐factor Child Behavior Scale (CBS) was assessed in a sample of 265 Peruvian preschool children who ranged from 2 to 6 years in age. Exploratory factor analysis yielded a four‐factor structure, and reliability estimates for scores on the four factors were adequate. The authors suggest replicating the study and examining the utility of CBS scores in predicting future problem behaviors in this population. © 2011 Wiley Periodicals, Inc.     

Interoperability and Information Integration in an Early Online Academic Digital Library of Theses and Dissertations: The Case of BTD

Cooperative organization has been proposed as a means to improve the usefulness of virtual libraries. Information interchange among library and other academic applications is often hindered by the lack of application interoperability. This hindrance may be overcome through the development of standards that allow for digital libraries to exchange and share information with other applications. The Graduate Program in Production Engineering (PPGEP) of the Federal University of Santa Catarina (UFSC) launched its Theses and Dissertations Bank (BTD) in 1995. BTD is possibly the first online academic digital library of theses. From a digital document repository, BTD evolved into a system that combines bibliometry and informetry features. BTD is used by students and faculty in their research activities, but also by decision makers from industry and academia. They use it, respectively, to search for specialists and to measure interest and knowledge interchange among PPGEP research areas. This article presents the history, features, and development prospects for the BTD project. The integration of BTD with other academic applications, especially those of the Brazilian national science and technology platform, is emphasized.     

Total Protein of Whole Saliva as a Biomarker of Anaerobic Threshold

Saliva provides a convenient and noninvasive matrix for assessing specific physiological parameters, including some biomarkers of exercise. We investigated whether the total protein concentration of whole saliva (TPWS) would reflect the anaerobic threshold during an incremental exercise test. After a warm-up period, 13 nonsmoking men performed a maximum incremental exercise on a cycle ergometer. Blood and stimulated saliva were collected during the test. The TPWS anaerobic threshold (PAT) was determined using the Dmax method. The PAT was correlated with the blood lactate anaerobic threshold (AT; r = .93, p < .05). No significant difference (p = .16) was observed between PAT and AT. Thus, TPWS provides a convenient and noninvasive matrix for determining the anaerobic threshold during incremental exercise tests.     

Updating a Classic: “The Poisson Distribution and the Supreme Court” Revisited

W.A. Wallis studied vacancies in the US Supreme Court over a 96‐year period (1837–1932) and found that the distribution of the number of vacancies per year could be characterized by a Poisson model. This note updates this classic study.
