The right to an identity: birth registration in Latin America and the Caribbean

A disturbing token of child and adolescent vulnerability in Latin America and the Caribbean is that so many are deprived of any legal identity by failure to report their birth. This bars them from exercising basic citizen rights and can hinder their access to productive employment, social benefits and the justice system and deny them recognition as full citizens and the right to well-being, capacity development and political participation.

Efeitos de atividades distrativas associadas à progressão do atraso sobre o responder autocontrolado de crianças

Estudos sobre autocontrole têm indicado dois procedimentos como eficazes para aumentar a emissão de respostas autocontroladas: a progressão do atraso do reforço e/ou o uso de atividades distrativas durante o atraso. Este estudo avaliou o efeito de dois tipos de atividades distrativas (lúdica e intelectual) associadas à progressão do atraso do reforço sobre o responder autocontrolado de crianças e a possível manutenção de respostas autocontroladas alcançadas nos treinos, em sessões posteriores com atraso para a troca de até 3 dias. Nove participantes de 5 a 7 anos foram expostos a uma situação de escolha entre dois estímulos apresentados na tela de um computador para obter fichas que posteriormente eram trocadas por itens. Escolhas impulsivas produziam 1 ficha (magnitude baixa) e escolhas autocontroladas produziam 3 fichas (magnitude alta). Havia 6 condições experimentais: (a) Linha de Base Magnitude: magnitude alta/0 s e magnitude baixa/0 s; (b) Linha de Base Atraso: magnitude baixa/0 s e magnitude baixa/60 s; (c) Aumento Progressivo: a magnitude baixa foi apresentada junto ao menor atraso e a magnitude alta foi apresentada junto ao maior atraso, que aumentou 10 segundos em 7 fases (0 s a 60 s) – Grupo A; (d) Aumento Progressivo Combinado à Atividade Lúdica: mesmas fases da condição anterior, mas era possível realizar atividade de colorir durante o atraso – Grupo B; (e) Aumento Progressivo Combinado à Atividade Intelectual: mesmas fases, mas era possível realizar atividade de resolver problemas matemáticos durante o atraso – Grupo C; e (f) Atraso na Troca: reforços (fichas) de magnitude alta e baixa foram entregues após a sessão, mas os de magnitude alta só eram trocadas por itens após 1, 2 ou 3 dias. Os resultados não mostraram diferenças consistentes entre os resultados dos treinos (só progressão, progressão com atividade lúdica e progressão com atividade intelectual). Porém, os dados sugerem que treino utilizando atividade intelectual durante o atraso do reforço pode ser menos eficaz para manter as respostas autocontroladas em períodos de atraso de um a 3 dias para a troca das fichas. De um modo geral, a utilização de atrasos maiores parece ter favorecido, mais que atrasos menores, a sensibilidade a variáveis externas não controladas no experimento.

Stability at different temperatures of turmeric oleoresin encapsulated in maltodextrin/gelatin matrices by freeze-drying

Turmeric (Curcuma longa L.), which has been used for long time as a spice, food preservative and coloring agent, is a rich source of beneficial phenolic compounds identified as curcuminoids. These phenolic compounds are known for their antioxidant, anti-inflammatory and antimutagenic properties, among others. On the other hand, they are very susceptible to oxidation, requiring protection against oxygen, light and heat. This protection can be achieved by microencapsulation. In this work, the characteristics and the stability of turmeric oleoresin encapsulated by freeze-drying using mixtures of maltodextrin and gelatin as wall materials were studied. Encapsulated turmeric oleoresin was stored at –20, 25 and 60 °C, in the absence of light, and analyzed over a period of 35 days for curcumin and total phenolic contents and color. Results showed that the samples produced with 26% maltodextrin/0.6% gelatin and 22% maltodextrin/3% gelatin presented good encapsulation efficiencies and solubility. In general, the method of encapsulation employed originated products with satisfactory thermal stability, although the encapsulated materials with a higher proportion of maltodextrin in relation to gelatin had better stabilities, especially at –20 and 25 °C temperatures.

Reflexões sobre o desencaixe na educação brasileira e o eventual impasse entre o docentrismo e o discentrismo

Undocked institutions widely dilate the scope of time-space distancing, since the separation between these elements is crucial for the extreme dynamism of modernity. This separation is the prime condition of the process of disembedding, in which the displacement of social relations of local contexts of interaction and its redesign through indefinite extensions of time and space are favored. Therefore, there are two types of dislocated mechanisms intrinsically involved in the development of social modern institutions: symbolic tokens and expert systems. These mechanisms depend on reliability. Within this context, this present paper sees the professional life cycle of the teacher in the perspective of the expert system. It also sees the work stability of public servants in the symbolic token perspective, more specifically public teachers in Brazil. This paper also attempts to propose some reflections on what a disembedding in Brazilian education would mean and on how an eventual impasse between teachercentrism and studentcentrism would affect this process if necessary or desired, from one would understand by modernity.

An unusual case of severe primary molar infraocclusion

Dentoalveolar ankylosis is described as the direct union between root cementum/dentin and alveolar bone. Its etiology is unknown, and conflicting opinions have been presented to explain it. Late detection of ankylosed primary teeth may cause serious problems to the occlusion and generally demands a more complex treatment approach. The purpose of this report is to present an unusual case of severe infraocclusion of the primary maxillary right second molar associated with a posterior crossbite in a 6-year-old child. The initial treatment option was tooth extraction, but the tooth resumed eruption spontaneously. After correction of the posterior crossbite and a 1-year follow-up, the tooth remained in occlusion and the permanent successor was developing without problems. From this unusual outcome, it may be concluded that further investigation of this anomaly of eruption is needed. (J Dent Child 2013;80(2):88-91)

Artifactual oxidation of cholesterol during the analysis of cholesterol oxidation products: protective effect of antioxidants

To study the influence of the addition of various antioxidants and their combinations on the artifactual oxidation of cholesterol during analysis, 2 factorial experiments were performed in duplicate. In the first experiment, 2 amounts of the following antioxidants were assayed: ethylenediaminetetraacetic acid (EDTA) disodium salt (0 and 1 mg), pyrogallol (0 and 600 microg), and butylated hydroxytoluene (BHT; 0 and 600 microg); in the second, EDTA disodium salt (0 and 1 mg), ascorbyl palmitate (0 and 600 microg), and BHT (0 and 600 microg). Under low oxidative conditions of dim light, evaporation of solvents at low temperatures, and cold saponification in darkness under nitrogen atmosphere, the addition of antioxidants showed no further protective effect. Furthermore, the presence of ascorbyl palmitate significantly increased the formation of cholesterol-5beta,6beta-epoxide, and 7beta-hydroxycholesterol.

Effect of gamma irradiation on caprolactam migration from multilayer polyamide 6 films into food simulants: development and validation of a gas chromatographic method

A GC method to determine caprolactam in water, 15 ethanol, and olive oil food simulants was developed and validated. Linear ranges varied from 0.96 to 642.82 g/mL for water, 0.64 to 800.32 g/mL for 15 ethanol, and 1.06 to 1062.34 g/g for olive oil, with correlation coefficients higher than 0.999. Method precision studies showed RSD values lower than 5.45, while method accuracy studies showed recovery from 72 to 111 for all simulants. The effect of gamma irradiation on caprolactam migration from multilayer polyamide 6 (PA-6) films intended for cheese into water, 15 ethanol, olive oil, and 3 acetic acid simulants was also studied. For migration assay, non-irradiated and irradiated (12 kGy) films were placed in contact with the simulant and exposed at 40C for 10 days. The validated method was used to quantify caprolactam migration from multilayer PA-6 films into the simulants, which ranged from 1.03 to 7.59 mg/kg for non-irradiated films, and from 4.82 to 11.32 mg/kg for irradiated films. Irradiation caused almost no changes in caprolactam levels, with the exception of olive oil, which showed an increase in the caprolactam level. All multilayer PA-6 films were in accordance with the requirements of the legislation for caprolactam migration.
