Are muscle activation patterns altered during shod and barefoot running with a forefoot footfall pattern?

This study aimed to investigate the activation of lower limb muscles during barefoot and shod running with forefoot or rearfoot footfall patterns. Nine habitually shod runners were asked to run straight for 20 m at self-selected speed. Ground reaction forces and thigh and shank muscle surface electromyographic (EMG) were recorded. EMG outcomes (EMG intensity [iEMG], latency between muscle activation and ground reaction force, latency between muscle pairs and co-activation index between muscle pairs) were compared across condition (shod and barefoot), running cycle epochs (pre-strike, strike, propulsion) and footfall (rearfoot and forefoot) by ANOVA. Condition affected iEMG at pre-strike epoch. Forefoot and rearfoot strike patterns induced different EMG activation time patterns affecting co-activation index for pairs of thigh and shank muscles. All these timing changes suggest that wearing shoes or not is less important for muscle activation than the way runners strike the foot on the ground. In conclusion, the guidance for changing external forces applied on lower limbs should be pointed to the question of rearfoot or forefoot footfall patterns.     

From the Theories of Social and Cultural Reproduction to the Theory of Resistance

The aim of this article is to articulate the theory of resistance with the theories of social and cultural reproduction, within the boundaries of the new sociology of education. Starting from the concepts of classification and framing developed by Basil Bernstein and of Pierre Bourdieu's social camp, the author defines some concepts which, in his opinion, are basic to establish the theory of resistance with conceptual rigour and analytical capacity. It will thus be possible to constitute a referential theoretical matrix for the development of counter‐hegemonic curricula, teaching materials and pedagogical practices, whose objective is to oppose the schools’ social and cultural reproduction in its different forms (of class, race, ethnic groups and gender), at its two levels—the reproduction of the sexual and social division of labour and of the inculcation of the dominant ideologies.     

Body dissatisfaction in women’s artistic gymnastics: A longitudinal study of psychosocial indicators

Body dissatisfaction is prevalent in women’s artistic gymnastics (WAG). Cross-sectional research points to social and individual risk factors, however it does not account for potential changes in body dissatisfaction during an athletic season. This study aimed to determine how gymnasts’ body dissatisfaction, risk factors for eating disorders, media internalisation, perfectionism and mood state change during pre-competition, competition and post-competition seasons and to identify how these psychosocial indicators impact on body dissatisfaction during the athletic year. The sample consisted of 20 Brazilian elite women’s artistic gymnasts aged 10–16 years. Data were obtained from a 9-month study using: Body Shape Questionnaire (BSQ); Eating Attitude Test-26; Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3); Multidimensional Perfectionism Scale (MPS); Brunel Mood Scale (BRUMS) and triceps and subscapular skinfolds. Body dissatisfaction was higher during the competition season and disordered eating, perfectionism and vigour values were higher in the pre-competition season. Disordered eating has been found as the strongest predictor of body dissatisfaction during all seasons, and mood state partly contributed to body dissatisfaction in the competitive season. Stakeholders should understand that body dissatisfaction and the prevalence of disordered eating may change over time.     

The World Bank’s position on early child education in Brazil: a critical assessment of contributions and shortcomings

In 2010, the World Bank published a policy study on early child education (ECE) developments in Brazil, entitled Early Child Education: Making Programs Work for Brazil’s Most Important Generation. Development. This paper analyses the report’s assessment of ECE policy in Brazil as well as the recommendations it provides. A critical analysis of ECE shows that the report’s insistence that financial constraints necessitate a trade-off between coverage and quality privileges the influence and position of the private sector and urges public–private partnerships as a cost-saving strategy. While it commends the Brazilian Government for its commitment to universal access to preschool, it argues for more targeted investment in quality rather than access. This paper argues that the quality-coverage debate should be set aside and overall investment in ECE should be increased. It also argues that issues excluded from the report such as disability, race and rural access to ECE must be considered in the development of sound social policy.     

Rethinking the Core List of Journals for Libraries that Serve Schools and Colleges of Pharmacy

The Core List of Journals for Libraries that Serve Schools and Colleges of Pharmacy is a guide for developing and maintaining pharmacy-affiliated library collections. A work group was created to update the list and design a process for updating that will streamline future revisions. Work group members searched the National Library of Medicine catalog for an initial list of journals and then applied inclusion criteria to narrow the list. The work group finalized the fifth edition of the list with 225 diverse publications and produced a sustainable set of criteria for journal inclusion, providing a structured, objective process for future updates.     

Gahvora cradling in Tajikistan: Cultural practices and associations with motor development

In Tajikistan, infants are bound supine in a “gahvora” cradle that severely restricts movement. Does cradling affect motor development and body growth? In three studies (2013–2018), we investigated associations between time in the gahvora (within days and across age) and motor skills and flattened head dimensions in 8–24-month-old Tajik infants (N = 269, 133 girls, 136 boys)) and 4.3–5.1-year-old children (N = 91, 53 girls, 38 boys). Infants had later motor onset ages relative to World Health Organization standards and pronounced brachycephaly; cradling predicted walk onset age and the proficiency of sitting, crawling, and walking. By 4–5 years, children's motor skills were comparable with US norms. Cultural differences in early experiences offer a unique lens onto developmental processes and equifinality in development.     

Technology as culture and embodied knowledge

An operational definition for knowledge is presented and, invoking the economic concept of a transformation process, a definition of technology emerges as a static form of knowledge embodied within a functional piece of some material form. The knowledge of a social group, or of the human kind, is then observable, at a certain moment in time, in its technological forms. In this sense, technology is the visible part of its culture. Microeconomic and macroeconomic views, as well as management understanding of what it is and which role technology plays, are also considered and discussed.
