ObjectivesSocial capital has been studied due to its contextual influence on health. However, no specific assessment tool has been developed and validated for the measurement of social capital among 12-year-old adolescent students. The aim of the present study was to develop and validate a quick, simple assessment tool to measure social capital among adolescent students.MethodsA questionnaire was developed based on a review of relevant literature. For such, searches were made of the Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, The Cochrane Library, ISI Web of Knowledge, International Database for Medical Literature and PubMed Central bibliographical databases from September 2011 to January 2014 for papers addressing assessment tools for the evaluation of social capital. Focus groups were also formed by adolescent students as well as health, educational and social professionals. The final assessment tool was administered to a convenience sample from two public schools (79 students) and one private school (22 students), comprising a final sample of 101 students. Reliability and internal consistency were evaluated using the Kappa coefficient and Cronbach's alpha coefficient, respectively. Content validity was determined by expert consensus as well as exploratory and confirmatory factor analysis.ResultsThe final version of the questionnaire was made up of 12 items. The total scale demonstrated very good internal consistency (Cronbach's alpha: 0.71). Reproducibility was also very good, as the Kappa coefficient was higher than 0.72 for the majority of items (range: 0.63 to 0.97). Factor analysis grouped the 12 items into four subscales: School Social Cohesion, School Friendships, Neighborhood Social Cohesion and Trust (school and neighborhood).ConclusionsThe present findings indicate the validity and reliability of the Social Capital Questionnaire for Adolescent Students.

RESUMO -O entendimento da nutrição das mudas e o uso de substratos de cultivo apropriados são essenciais para definição da recomendação adequada de fertilização. Devido à dificuldade de se fazerem recomendações de fertilização específicas, testou-se o efeito da adubação nitrogenada no crescimento e qualidade das mudas de sete-cascas (Samanea inopinata). Foram estudados nove tratamentos com três repetições cada e parcelas com seis sacolas plásticas, em delineamento de blocos ao acaso. A fonte de nitrogênio utilizada foi o sulfato de amônio aplicado sob diferentes dosagens (0, 0,7; 1,4; 2,1; e 2,8 g/muda) a cada 14 ou 28 dias. O experimento foi acompanhado por 12 meses, sendo, então, colhido. Avaliaram-se a altura (H), diâmetro do coleto (D) e matéria seca da parte aérea (MSPA) e da raiz (MSR), calculando-se a matéria seca total (MST) e os índices de qualidade de mudas: H/D, H/MSPA, MSPA/MSR e o IQD. Procedeu-se à análise estatística por análise fatorial e de regressão. Todos os parâmetros morfológicos avaliados foram afetados significativamente, com exceção dos índices MSPA/MSR e H/D. Devido à importância da altura e do diâmetro, recomenda-se aplicar 0,91 g de sulfato de amônio por muda a cada 14 dias, quando cultivadas em Latossolo Vermelho-Amarelo combinado com composto orgânico.Palavras-chave: Nitrogênio, nutrição de plantas, espécies nativas e produção de mudas.ABSTRACT -Understanding seedling nutrition and the use of appropriate substrata for cultivation are essential to define fertilization recommendations. Due to the difficulty in making specific fertilization recommendations, the effect of nitrogen fertilization was tested on the growth and quality of sete-cascas (Samanea inopinata) seedlings. The experiment consisted of nine treatments with three repetitions each and six plastic bags per parcel, in randomized block design. The nitrogen source was ammonium sulfate applied at different levels every 14 or 28 days. The experiment was monitored for twelve months, and then harvested. The following parameters were evaluated: height (H), root collar diameter (D), dry matter of aerial part (MSPA) and root (MSR), total dry matter (MST) and seedling quality indexes H/D, H/MSPA, MSPA/MSR and IQD were calculated. The data were analyzed using factorial and regression analysis. All the tested morphological parameters were significantly affected by the nitrogen fertilization, except for the MSPA/MSR and H/D indexes. Due to the height and diameter importance, it was recommended 0.91 g of ammonium sulfate per seedling every 14 days when cultivated in Red-Yellow Latosol, combined with organic compost.

Prevalence of traumatic dental injury was high among the children who participated in the study, and it was associated with a high impact on oral health-related quality of life as well as overjet >3 mm.

As respostas à aplicação dos demais nutrientes (Ca, Mg e K), em muitos casos, não ocorreu, evidenciando-se que a espécie tem baixo requerimento por eles. Entretanto, partindo desse estudo, sugerem-se novos estudos com os nutrientes K e Ca, para produção de mudas da referida espécie nesses solos.Palavras-chave: Angico-vermelho, macronutrientes e produção de mudas.

RESUMO -Objetivou-se com o presente estudo avaliar a eficiência da técnica de miniestaquia na propagação vegetativa de progênies de meios-irmãos de angico-vermelho (Anadenanthera macrocarpa (Benth) Brenan) quanto à produção de brotações e sobrevivência das minicepas, enraizamento das miniestacas apicais e intermediárias tratadas com diferentes doses do AIB (0; 2.000; 4.000 e 6.000 mg L -1 ), assim como determinar a velocidade de enraizamento em casa de vegetação. As minicepas foram obtidas a partir de mudas produzidas via sementes de seis progênies de meios-irmãos de angico-vermelho. Com base nos resultados obtidos, as minicepas apresentaram produtividade de 1,2 a 3,7 miniestacas/minicepa/coleta e sobrevivência de 84% a 98% ao longo das seis coletas realizadas. As miniestacas apicais foram superiores em relação às intermediárias, com maior predisposição ao enraizamento, no entanto o AIB não teve efeito significativo sobre o enraizamento das progênies estudadas. Quanto à velocidade de enraizamento, os resultados indicaram variação entre as progênies.Palavras-chave: Produção de mudas, Enraizamento e Silvicultura clonal.
