Abstract: The effect of including detoxified castor bean meal to substitute soy bean meal was evaluated to sheep finishing diets on intake, digestibility and energy value of the diets. A positive linear effect was verified for ether extract intake and acid detergent fiber with an intake raise of 0.015 g/BW0.75 in ether extract and 0.090 g/BW0.75 in acid detergent fiber per each unit percentage of detoxified castor bean meal added to the diet. There was maximun value in hemicellulose intake when included 39.55% of detoxified castor bean meal to the diet. Negative linear effect was verified for dry matter, organic matter, crude protein, total carbohydrates digestibility, respectively, with 0.0536, 0.0507, 0.0705 and 0.0572% decreases per unit percentage of detoxified castor bean meal added. Positive quadratic effect was verified for neutral detergent fiber and hemicellulose digestibility with 54.93 and 64.53% maximum in levels of the 38.6 and 31.4, respectively. Detoxified castor bean meal inclusion does not influence dry matter and nutrients intake, attending these animal class nutritional requirements. Including detoxified castor bean meal decreases dry mater, organic matter, crude protein, total carbohydrates digestibility, being in this situation recommended the inclusion of to 33% in the diet by allowing high neutral detergent fiber and hemicellulose digestibility. Despite these effects, the energy value of the diets is not influenced by the inclusion of detoxified castor bean meal. Avaliou-se a substitui o do farelo de soja pelo farelo de mamona destoxificado em dietas para ovinos em termina o. O consumo de extrato etéreo e fibra em detergente ácido foi linear positivo, com aumento de 0,015 e 0,090g/UTM por unidade percentual de inclus o de farelo de mamona destoxificado, respectivamente. O consumo máximo de hemicelulose ocorreu para dietas que continham 39,55% de farelo de mamona destoxificado. A digestibilidade da matéria seca, matéria organica, proteína bruta e carboidratos totais decresceu linearmente em 0,0536; 0,0507; 0,0705 e 0,0572%, respectivamente, por unidade percentual de acréscimo de farelo de mamona destoxificado. Os valores máximos para digestibilidade da fibra em detergente neutro e hemicelulose, 54,93 e 64,53%, ocorreram para dietas que continham 38,6 e 31,4% de farelo de mamona destoxificado, respectivamente. A inclus o de farelo de mamona destoxificado n o influencia o consumo de matéria seca e nutrientes e possibilita atendimento às exigências nutricionais de ovinos em termina o.

Abstract: Avaliou-se o efeito da inclus o de 0; 33; 67 e 100% do farelo de mamona destoxificado (FMD) em substitui o ao farelo de soja em dietas para ovinos em termina o sobre o metabolismo dos compostos nitrogenados, em delineamento de blocos ao acaso em parcelas subdivididas (tempos de coleta líquido ruminal e sangue), com cinco animais por tratamento. N o houve efeito (p > 0,05) sobre os parametros de metabolismo de nitrogênio, Ningerido, Nfecal, Nurinário, Nabsorvido e Nretido (g dia-1), rela o Nfecal/Ningerido e Nurinário/Ningerido (%), Nfecal/Nurinário (g g-1) e balan o de nitrogênio (%), com médias 26,70 ± 5,50; 8,73 ± 1,79; 2,17 ± 0,71; 17,96 ± 3,98; 15,78 ± 3,17; 32,90 ± 2,82; 7,89 ± 2,55; 5,08 ± 1,61 e 59,19 ± 4,68, respectivamente. As dietas influenciaram (p < 0,05) os valores de pH e N-NH3 no líquido ruminal (LR) e ureia no soro sanguíneo, com intera o (p < 0,05) dos níveis de inclus o de farelo de mamona nas dietas x tempos de coleta de LR e sangue apenas para os teores de N-NH3 ureia no soro sanguíneo. O farelo de mamona destoxificado pode ser utilizado em substitui o ao farelo de soja em dietas para ovinos em termina o, por n o influenciar o metabolismo donitrogênio, com estabilidade do pH ruminal, da concentra o de N-NH3 no líquido ruminal e de ureia no soro sanguíneo em rela o aos intervalos fisiológicos normais para a espécie ovina. Neste caso, o nível de inclus o deste coproduto na dieta de ovinos deve ser realizado de acordo com a viabilidade econ mica da substitui o. The study evaluated the effect of levels 0, 33, 67 and 100% of detoxified castor bean meal (DCBM) to replace soybean meal on nitrogen metabolism in diets for finishing sheep. The experimental design was randomized blocks in a split plot design (plot = levels of DCBM, and subplot = four collection times of ruminal liquid or blood: 0, 2.5, 5 and 7.5h), with five animals per treatment. No effect (p > 0.05) was verified on nitrogen metabolism parameters: Nintake,Nfaeces, Nurinary, Nabsorbed and Nretained (g day-1), Nfaeces/Nintake, Nurinary/Nintake (%) and Nfecal/Nurinary (g g-1)ratio and nitrogen balance (%), with means 26.70 ± 5.50, 8.73 ± 1.79, 2.17 ± 0.71, 17.96 ± 3.98, 15.78 ± 3.17, 32.90 ± 2.82, 7.89 ± 2.55, 5.08 ± 1.61 and 59.19 ± 4.68, respectively. The diets influenced (p < 0.05) pH and N-NH3 in ruminal fluid (RF) and blood urea concentrations, with interaction (p < 0.05) levels of inclusion of castor bean meal x collection times of RF and blood only for N-NH3 and urea concentrations. Detoxified castor bean meal can be used to replace soybean meal in diets for finis

Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.76085
Abstract:

This study addressed the psychometric properties of the Children’s Social Skills Test (THAS-C). Results were divided into two parts. Initial studies investigated 257 children attending Grades 2 to 4 in public schools of two cities in the countryside of the state of São Paulo. Study 2 assessed 1381 children and adolescents aged 7 to 15 years from public and private schools in cities located in the countryside of the state of São Paulo. Infit and outfit indexes showed adequate fit for both items and people. A progression analysis using Rasch measurement model showed greater people’s ability in function of response categories. On the other hand, the outfit index suggested good fit in all categories. These data show relevance for the structure of three analysis categories. Few items showed DIF. Precision data obtained with these two methods showed satisfactory indexes. These data enable validity evidences based on the internal structure. Such findings may facilitate the assessment process and planning of interventions that are more focused on individual needs.

Abstract: A prevalência de inseguran a alimentar é importante para a avalia o das condi es de vida e para o planejamento de políticas públicas de combate à fome. A pesquisa foi realizada com 177 famílias de S o José dos Ramos-PB, no ano de 2005, por meio de entrevista. A análise dos dados, por regress o logística e ODDS RATIO, utilizou como variável dependente estar ou n o em seguran a alimentar, avalia o resultante da aplica o da EBIA; e, como variável independente dicot mica, o consumo de 15 conjuntos de alimentos. O modelo em regress o logística e o odds ratio mostraram associa o de leite integral, manteiga, biscoito, bolacha e bolo com a seguran a alimentar. Contudo, deve-se levar em considera o o conceito ampliado de Seguran a Alimentar e Nutricional, que enfatiza outros fatores relevantes além do consumo alimentar, como a disponibilidade de alimento, que se incorpora às condi es de renda e padr o de vida. The prevalence of food insecurity is important for the assessment of the conditions of life and planning of public policies for combating hunger. The survey was conducted with 177 families of S o José dos Ramos, in the year 2005, through interview. Data analysis, through logistics regression and ODDS RATIO, used as the dependent variable is in food safety assessment resulting from the application of EBIA, and as a variable dichotomic-independent consumption of 15 sets of food. The regression model Logistics and the odds ration of Association showed whole milk; butter, biscuit, cracker, cake with food safety. However you should take into consideration the expanded concept food and nutritional security that emphasizes other relevant factors beyond the food consumption as food availability, which incorporates income conditions and standard of living.

Abstract: Este artigo pretende apresentar uma aplica o do modelo SERVQUAL à avalia o educacional. Seu emprego ocorreu junto aos discentes de cursos de pós-gradua o lato sensu de uma institui o paranaense, cuja estratégia para capta o de alunos baseia-se na flexibiliza o da grade curricular, do horário das aulas e das formas de pagamento. A relevancia deste trabalho deve-se ao fato de que o aperfei oamento de qualquer sistema educacional depende, necessariamente, de avalia es, e estas carecem de modelos adequados e abrangentes que forne am parametros comparáveis, confiáveis e relevantes para a tomada de decis es gerenciais e pedagógicas. Em seus resultados, o trabalho destaca, de modo geral, que a institui o atende às expectativas dos respondentes. Porém, alguns pontos críticos, passíveis de melhoria, foram notados e serviram de base para a discuss o sobre a qualidade do ensino nas escolas de Administra o. The SERVQUAL model was used for an educational evaluation with students of a post-graduate course lato sensu at an institution in Parana state. There the strategy for attracting students is based on the flexibility of courses offered, class schedules and options for payment. Relevance of this work is related to the fact that improvement of an educational system depends upon evaluations and that these lack adequate and comprehensive models to provide comparable, dependable and relevant parameters for managerial and pedagogical decisions. Results stress that the institution generally meets expectations. However, some critical aspects, subject to improvement, were noted and utilized to discuss the quality of education in business administration schools.

Abstract: the collective management of public policies requires new relationships, both democratic and dialogical, between society and the state. it also requires the construction of institutional structures that are capable of sustaining it and of strengthening non-state public spaces. in municipal boundaries, the management councils are important players in these processes. from these considerations, this essay discusses some assumptions so that they are, in fact, foundations of deliberative democracy - understood as a method for formation of collective decisions by means of dialogue between politically equal individuals. in order to organize the argument, the conditions of effectiveness were divided into three categories. the first concentrates on elements related to the formal organization of councils. the following discusses aspects relating to their deliberative process. issues concerning the connection of councils with social groups and local powers lie within the latter category.

Abstract: it is argued that the connection between the activities of teaching, researching and extension as a guiding principle to the quality of the superior education. although we consider the important links that can be established between only two of those activities, we argue that the articulation of those three activities prevents isolated practices verified in superior education. guided by that principle, as post-graduation students, we accomplished an intervention in a public local school in jo?o pessoa (pb). that intervention is presented in this text as an experience that aimed to link scientific discoveries and the educators' and students' understanding about the articulation of gender relationships, violence and electronic games in school. two central ideas are supported: first, the connection between teaching, research and extension is not still taken into account in practice of many professors in universities, either because in the graduation the emphasis is on teaching, or because in post graduation the emphasis is on research. secondly, post graduation is an excellent occasion to practice the connection between the three academic activities.

Abstract: A desregulamenta o do mercado cafeeiro propiciou uma nova conjuntura institucional. Nesse cenário, buscou-se investir em estratégias de diferencia o e na cria o de associa es orientadas para implementá-las. é pertinente discutir o papel dessas organiza es nesse contexto. O objetivo deste artigo é discutir a expans o do papel das associa es de cafeicultores brasileiros, enfocando o suporte que tais organiza es oferecem para que seus membros possam atuar com produtos diferenciados. Trata-se de um ensaio sobre o papel das associa es de interesse privado sob o prisma da Economia dos Custos de Transa o, das Redes e do Capital Social. Deregulation of the coffee market provided a new institutional scenario where investments in differentiation strategies were sought and private interest associations were formed to carry out these strategies. This situation was discussed together with the growing role of associations of Brazilian coffee producers which were focused on supporting members promoting differentiated products. A description of these associations was presented from the standpoint of transaction cost economics, networks and capital stock.

Abstract: Este trabalho busca evidenciar a rela o entre os conceitos obtidos pelas escolas de Administra o no Exame Nacional de Cursos e seus respectivos perfis de qualifica o e de dedica o docente em 2000, 2001 e 2002. Em seus resultados, descreve a distribui o das institui es de ensino a partir das variáveis "conceitos obtidos", "localiza o geográfica" e "categoria administrativa". Emprega, ainda, o método estatístico de análise de correspondência para ilustrar a associa o entre conceitos "A" e elevados percentuais de professores com doutorado e dedica o exclusiva. Nas considera es finais, o trabalho aponta possíveis fatores impeditivos da melhoria dos índices de dedica o e qualifica o docente (como o tempo demandado para a forma o de doutores, a assimetria entre os sistemas de gradua o e pós-gradua o em Administra o e a sistemática de remunera o por horas-aula) e exp e limita es e oportunidades para novas pesquisas. An evaluation was made of the relations between the ratings obtained by the schools of Administration in the National Evaluation of Courses and the respective profiles of qualification and commitment of teachers in 2000, 2001 and 2002. Results describe the distribution of the educational institutions based upon the variables of rating achieved, geographic location and administrative category. Statistical correspondence analysis disclosed the association between the top rating "A' and the higher percentages related to professors with a doctorate title and full time commitment. The work concludes with factors that may hinder an improvement of teacher ratings for commitment and qualification. They include the time required for a doctorate title, the asymmetry between the systems of graduation and post graduation in Administration and the remuneration system for class hours as well as exposing the limitations and opportunities for research.
