Rastreabilidade da farinha de carne e ossos bovinos em ovos de poedeiras comerciais pela técnica dos isótopos estáveis do carbono e nitrogênio

Objetivou-se com este estudo rastrear a inclusão de farinha de carne e ossos bovinos em dietas para poedeiras comerciais, por meio da análise dos ovos e de suas frações (gema e albúmen), pela técnica dos isótopos estáveis do carbono e nitrogênio e avaliar o índice analítico mínimo detectável. Foram utilizadas 240 galinhas poedeiras da linhagem Shaver White de 73 semanas de idade, distribuídas em delineamento inteiramente casualizado, com cinco tratamentos e seis repetições. Foram avaliados cinco níveis de inclusão (0; 1,5; 3,0; 4,5 e 6,0%) de farinha de carne e ossos bovinos em uma dieta à base de milho e farelo de soja. No 35º dia, foram tomados aleatoriamente 24 ovos por tratamento: 12 serviram para amostragem de gema e albúmen e os outros 12 para amostragem do ovo (gema + albúmen). Os resultados isotópicos foram submetidos à análise multivariada de variância e, a partir das matrizes de erro, com 95% de confiança, foram determinadas elipses para identificar as diferenças entre os resultados obtidos com o fornecimento das dietas experimentais e a dieta controle, sem farinha de carne e ossos bovinos. No ovo e na gema, a partir do par isotópico da dieta com 3,0% de farinha de carne e ossos, houve diferenciação do par do tratamento controle, enquanto, no albúmen, a diferenciação ocorreu a partir do nível de 1,5% de farinha de carne e ossos bovinos na dieta. Pela técnica dos isótopos estáveis, é possível rastrear o uso de farinha de carne e ossos bovinos na alimentação de poedeiras; no albúmen, o nível mínimo de inclusão detectável é de 1,5% e, no ovo e na gema, 3,0%.

Traceability of animal byproducts in quail (Coturnix coturnix japonica) tissues using carbon (13C/12C) and nitrogen (15N/14N) stable isotopes

Consistent information on meat products consumed by the public is essential. The technique of stable isotopes is a powerful tool to recover consumers' confidence, as it allows the detection of animal byproduct residues in poultry meat, particularly in quail meat. This study aimed at checking the presence of poultry byproduct mixtures in quail diets by applying the technique of carbon (13C/12C) and nitrogen (15N/14N) stable isotopes in quail breast muscle, keel, and tibia. Sixty four one-day-old male quails were obtained from a commercial farm. Birds were housed in an experimental house from one to 42 days of age, and were randomly distributed into 8 experimental treatments, and fed diets containing poultry offal meal (POM), bovine meat and bone meal (MBM) or poultry feather meal (PFM), or their mixtures. Four birds per treatment were slaughtered at 42 days of age, and breast (Pectoralis major), keel, and tibia were collected for analyses. The inclusion of animal byproducts in quail diets was detected by 13C e 15N analyses in the tissues of the birds; however, it was not possible to specify which byproducts were used. It was concluded that quail meat can be certified by the technique of stable isotopes.

Um estudo sobre a utilização de sistemas, programas e ferramentas da qualidade em empresas do interior de São Paulo

O desenvolvimento e implantação de sistemas de gestão da qualidade e o uso de programas e ferramentas da qualidade são algumas das opções mais utilizadas pelos gestores para aumentar a competitividade de suas empresas. Nesse contexto, o objetivo deste artigo é apresentar o resultado de uma pesquisa tipo survey em que se verificaram e analisaram as principais características do processo de certificação ISO 9001, seus benefícios, suas dificuldades e quais programas e ferramentas da qualidade são utilizados em 236 empresas do interior do Estado de São Paulo. A pesquisa revelou que a certificação ISO 9001 gera benefícios significativos às organizações, tais como: melhoria dos processos internos e nos seus produtos; aumento da satisfação dos clientes; diminuição do número de não conformidades e de devoluções; aumento da produtividade e do lucro; melhoria no gerenciamento dos recursos e valorização da imagem da empresa no mercado. Ela também ratificou a importância da utilização dos programas e ferramentas da qualidade como forma de as empresas se adequarem melhor aos requisitos da norma ISO 9001. As dificuldades de desenvolvimento e implantação desses sistemas não se confirmaram para a amostra pesquisada. Apenas a resistência à mudança, dentre todas apresentadas, mereceu destaque para os pesquisados.

Educação de educadores: pressuposto psicanalítico ou utopia reichiana?

Bien plus qu'on le pense, les prémices reichiennes semblent être basées sur des propositions freudiennes, surtout celles des premiers temps. Basée sur des justificatifs de différents ordres, desquels le plus usuel est que Reich était lié officiellement à l Association Psychanalytique Internationale, certains auteurs cependant exaltent les approches cliniques de cette « période psychanalytique » propre aux premières élaborations reichiennes, sans mentionner d'autres approches possibles dans la polémique en question. Ce n'est pas pour un autre motif que ce texte vise à racheter certaines des réflexions freudiennes sur l'éducation, mettant en évidence « l'éducation des éducateurs », soit comme un présupposé psychanalytique basé sur des textes éducatifs de Freud, soit comme une utopie typiquement reichienne, misant sur la possibilité d'une prophylaxie des névroses étendue au domaine éducatif ou comme un des points communs entre le discours éducatif de Freud ou de Reich, capable donc de favoriser au second le dédoublement de présupposés manifestés dans l uvre du premier.

Aplicação do earned value em projetos complexos - um estudo de caso na EMBRAER

O gerenciamento do Earned Value vem obtendo aceitação crescente nas empresas e entre profissionais tais como gerentes de projetos e funcionais, devido à sua efetividade no controle dos resultados do projeto. Earned Value é definido como uma ferramenta de controle que permite avaliar simultaneamente de maneira quantitativa como se encontram os custos e prazos em uma data de controle, permitindo também prever a data de término e o valor gasto (VARGAS, 2005). Este artigo avalia a aplicabilidade do earned value como ferramenta de controle de projetos aeronáuticos na EMBRAER. Contribui também para a aplicação do earned value no controle de projetos complexos. Utilizam-se como técnicas de coleta de dados: entrevistas, observações e análise documental. Conclui-se que o earned value é utilizado apenas nos projetos da área de aviação de defesa, por ser uma exigência contratual. O uso do earned value nas áreas de programas executivos e comerciais restringe-se às fases de definição conjunta, projeto detalhado e certificação, pois o escopo do projeto é bem definido, o cronograma é detalhado e os custos são previstos e obtidos com maior acuidade. Nas demais fases de desenvolvimento do produto, o uso do earned value é restrito, devido principalmente às constantes alterações de escopo do produto e do projeto.

International recommendations for training future toxicologic pathologists participating in regulatory-type, nonclinical toxicity studies

The International Federation of Societies of Toxicologic Pathologists (IFSTP) proposes a common global framework for training future toxicologic pathologists who will support regulatory-type - nonclinical toxicology studies. Trainees optimally should undertake a scientific curriculum of at least 5 years at an accredited institution leading to a clinical degree (veterinary medicine or medicine). Trainees should then obtain 4 or more years of intensive pathology practice during a residency and/or on-the-job "apprenticeship," at least 2 years of which must be focused on regulatory-type toxicologic pathology topics. Possession of a recognized pathology qualification (i.e., certification) is highly recommended. A nonclinical pathway (e.g., a graduate degree in medical biology or pathology) may be possible if medically trained pathologists are scarce, but this option is not optimal. Regular, lifelong continuing education (peer review of nonclinical studies, professional meetings, reading, short courses) will be necessary to maintain and enhance one's understanding of current toxicologic pathology knowledge, skills, and tools. This framework should provide a rigorous yet flexible way to reliably train future toxicologic pathologists to generate, interpret, integrate, and communicate data in regulatory-type, nonclinical toxicology studies.

Os quatro núcleos/eixos de produção da poética de Caio Fernando Abreu

This article presents a short study about the literary work of Brazilian writer Caio Fernando Abreu (1946-1996). In order to study his formal and thematic choices, we established criteria based on concepts like motif and plot (dramatic situation), as developed by Tomachevski (1976). A specific articulation between motives and dramatic situations establishes four nuclei of Abreu's literary production, which is characterized by a literary experimentation with these elements and it constructs an organic work that makes itself and/or is made in a dialogic way (Bakhtin, 1981). Firstly, the main characteristics of the four nuclei and the books that embody them will be presented. Then, we will describe how the motives and dramatic situations are re-elaborated from one nucleus to another. Not only does each nucleus features some new elements, but also contains remainders of previous ones. As such, each of Abreu's works can be considered as both the same and unique.

Construction and validation of the brazilian questionário de respostas socialmente habilidosas segundo relato de professores (QRSH-PR)

Behavioral problems in preschool children are one of the most frequent motives for seeking psychological care by parents and caregivers. Instruments are considered necessary, created from a Social Skills Training theoretical-practical perspective, which may systematically assist the identification of social skills and behavioral deficits, helping professionals in the prevention and/or reduction of behavioral problems. The purpose of this study was to test the psychometric validity and reliability of an instrument for evaluation of Socially Skilled Responses, from a teacher's perspective (QRSH-PR For this purpose, 260 preschool children were evaluated, differentiated in subgroups without and without behavioral difficulties, based on the Child Behavior Scale (Escala de Comportamento Infantil/ECI-Professor Studies were conducted for construct, discrimination, concurrent and predictive validity. The Cronbach Alpha was calculated to evaluate internal consistency. The obtained results pointed to positive indicators in reference to construct, discrimination, and predictive validity, and even for good internal consistency, indicating that the items consistently measure the construct of social skills, and differentiated children with and without behavioral problems. The questionnaire is considered to be gauged for evaluation of socially skilled responses from preschool children, and applicable in educational and clinical environments.

O Agronegócio e o problema do trabalho infantil

This article attempts to identify and analyze the motives that led several sectors of agro-business to engage in the struggle for the eradication of child labor in Brazil, as launched by international organizations for the defense of children's and adolescents' rights. It is our hypothesis that economic globalization and the internationalization of children's rights have given visibility to the problem of child labor, thus demanding the mobilization of entrepreneurial sectors linked to agro-business productive chains in Brazil. The article is divided into four inter-related sections. In the first one, we attempt to provide evidence for the interference of social and labor problems within the ambit of the economic activities of the agro-business sector, within the current context of globalization. This is followed by a study of major UN, UNICEF and ILO investments to internalize children's rights and policies to combat child labor, giving salience to their repercussions in Brazil. In the third section, we analyze strategies adopted by firms linked to agro-business with the purpose of avoiding the use of child labor within their productive chains. Finally, we seek to understand the motivations that have led agro-businessmen to take part in the struggle against child labor. We conclude that firms linked to agro-business took up the project of combating child labor in virtue of the internationalization of children and adolescents' rights, the inclusion of social issues in international markets, the intensification of the fiscalization of public power, the growth of action around entrepreneurial social responsibility and increased consumer consciousness.
