RESUMEN Este artículo presenta, en primer lugar, un recorrido por las ideas infantiles sobre el derecho a la intimidad realizado en nuestras investigaciones. En segundo lugar, muestra un rastreo bibliográfico de investigaciones que ponen de relieve el tratamiento institucional que tienen las escuelas sobre los derechos infantiles

Our results demonstrate that many patients with pKCS showed psychological problems and disturbances. We therefore recommend an additional psychological treatment (e.g. autogenic training) for these patients to stabilize their emotional condition, which may even have a positive effect on their dry eye problems.

Objective The aims of this study were to investigate the prevalence of sports injuries in school physical education (PE) and leisure-time sports among 1011 15- to 16-year-old adolescents in relation to physical activity, and to examine goal orientation. Methods A survey was used with additional narrative descriptions. Results There was a higher prevalence of injuries in leisure time (645/993 = 65%) than in PE (519/998 = 52%). Two groups with high PE injury rates were identified: a) highly active (258/998 = 26%) in both school PE and leisure-time sports and b) highly inactive (180/998 = 18%) in both contexts. There were no differences between girls and boys. Task-oriented adolescents were more prone to injury. Conclusions The high prevalence of injuries in PE appears to have two mechanisms: renewed inadequately recovered leisure-time injuries among highly active adolescents, and injuries among fragile inactive adolescents unfamiliar with exercise. PE educators of these two groups with different injury patterns have a considerable didactic challenge. Knowledge of inadequately recovered injuries and consideration of the high volume and intensity of early sport-specific training in children and adolescents are important parameters in the design of lesson plans for PE.

A comparison of Rietveld refinement results for a bauxite-bearing regolith and its clayey cover in the Amazon region was made with stoichiometric calculations from chemical analysis and partly from thermogravimetric results. For this investigation a profile in the bauxite-bearing regolith occurrence in the ALCOA bauxite mine at Juruti, Brazil was studied. The different minerals, their compositions and their low crystallinity in the different horizons were investigated and the contents determined. It is evident that some minerals show several generations and some chemical composition changes that must be included in the Rietveld refinement. Al-rich hematites and goethites are common along the bauxite profile. Amorphous contents were determined with rutile added as an internal standard and shown to have gibbsite- or kaolinite-like composition. The minerals could be quantified in the different horizons and the difficulties were mainly related to variable crystalline aspects of the phases. Rietveld refinement can be a powerful tool in bauxite prospecting, quality control and during mining and beneficiation of ore minerals using the adapted refinement strategies.

Though context has yet to receive an unequivocal definition, it is a concept that frequently appears in research in children's knowledge and its construction. This article examines the scope and meaning of context in genetic psychology and social anthropology in order to better understand the relationship between children's construction of knowledge and the context in which it occurs. Meta-theoretical, theoretical and methodological complexities arise when the concept is analyzed in the two disciplines, and these will also be addressed herein. The fields of anthropology and constructive psychology are both affected by the relationship between the building of knowledge and the social practices surrounding this process. Finally, based on these empirical examinations, the article explores how research methodologies could incorporate the notion of context in research focused on the construction of knowledge.
