Resolutions of the Board of numbers 359 and 360, of December 23, 2003, relating to Nutrition Labelling for Packaged Foods, establish quality standards and provide the education activities for health consumption, since one of the factors that enable the selection of healthier foods are the food labels as an important part in nutrition education. This is a descriptive study with a cross-sectional design. To calculate sample size, it was considered a margin of error of 20%, confidence level of 95% and prevalence of 52.5% for verifying nutritional information in a pilot study conducted in 2007. A total of 145 subjects were interviewed, resulting in 371 consumers in Natal, Rio Grande do Norte, Brazil, in order to determine prevalence of consulting nutritional information contained on food labels as a nutritional guideline for consumers and its association with sociodemographic variables as well as identify the intervention measures suggested by intervieweds so that this information can be better used to select healthy foods. Twenty-five of the 69 supermarkets belonging to the Supermarket Association of Rio Grande do Norte (ASSURN) were randomly selected. Data collection relied on interviews and extensive direct observation, using a semi-structured form composed of eight closed questions, some of which were multiple choice, and ten open questions. The chi-square test was performed for statistical analysis, using Statistical Package for Social Sciences (SPSS) 15.0 software. Label information most consulted was: expiry date (91.6%); product brand (49.4%); nutritional information (47.0%); zero trans fat (32.9%); zero sugar content (12.8%); zero fat content (3.0%); rich in fibers (2.7%); whether light or diet (30.4%); list of ingredients (16.8%); whether the product contained gluten or not (4.1%). When asked about the importance of nutritional information, 96.8% of the subjects responded important or very important ; of these 46.6% and 3.8% reported partially or totally understanding the information presented. It was found that 41.6% of the consumers consulted nutritional information for dietary reasons related to nontransmissible chronic diseases and 35.7% to be able to choose healthier foods. The data show a significant association between motivation to choose healthier foods and higher family income and schooling (p<0.0001). The intervention measures mentioned to make nutritional information better understood and used were: information and orientation about nutritional information, provided by qualified professionals in the supermarkets, the commercial establishment or the product manufacturer (73.9%) and media disclosure about the nature, importance and purpose of nutritional information (42.9%). In despite of communication noises the consumers use the nutrition claim for the nutritional guidance, showing association with some demographic variables. However, they desire the implementation of intervention measures that can be contextualized in the political construction of nutrition education to promote healthy food choices

Brazilian exportations come growing in a constant form in the last years, stimulated for the globalization and public politics directed toward the increase of the internal surplus. In this context the objective of this work was to investigate the perception of the shrimp exporting entrepreneurs of Rio Grande do Norte, with relation to the impact of the Brazilian environmental legislation in the companies competitiveness at the external market. From data collected from the controllers of the companies, it was used a survey methodology, with exploratory and descriptive character. The results found in this study indicate that the companies, in general way, understand that the environmental legal requirements do not confuse nor help in the search and conquest of new international markets. A little more of the half of the researched companies, does not see the legislation rigid as important factor of competitiveness. However a sufficiently significant percentage, already has a more strategical vision on the subject, or at least already it heard to speak on such possibility

The acquisition of machinery used in timber harvesting depends on high financial investment, which implies the need for assessments that allow defining more precisely, what is the machine or the whole more recommended for streamlining the operation. This study aimed to technically and economically evaluating the performance of a harvester in Eucalyptus forest harvest first cut. The technique analysis included a time and movements, productivity, efficiency operational and mechanical availability. The economic analysis included the parameters operational cost, harvesting cost and energy consumption. The results obtained from the technological-economic parameters evidenced that of Diameter at Breast Height directly influenced the productivity of harvester. Consequently the lower costs of forest harvest were obtained for the compartments with wider diameter trees.

This paper is set in a scenario in which higher education institutions suffer from external pressure to increase efficiency. The legislation after the Law of Directives and Bases for Education (LDBE), from 1996, is characterized by the fragmentation in its implementation, raising a concern with flexibility and innovation in several normative devices as well as aspects that must be incorporated to its organizational structure. The policies examined in this thesis are: Distance Education (DE); Law of Innovation and the Program of Support to Restructuring and Expansion of Federal Universities (PSREFU). This thesis aims to observe to what extent the characteristics of innovation and flexibility, which mark the new post- LDBE educational legislation, influence the organizational redesign of the Federal University of Ceará (UFC). For being about implementation policies, using contingency approach in order to collect the internal dynamics permeating the redesign of higher education institutions, the thesis focuses on the impacts caused by flexibility and innovation. This is a qualitative research, with case study methods, archive research and semi-structured interviews with members of the university administration. The results don t allow us to confirm the adoption of a more flexible and innovative configuration in the university but it is possible to identify the presence of those elements in the implementation changes, characterizing the hybrid structure. The changes mainly expose the extension of the management of projects to the administrative and academic components related to the institution. In terms of projection, the study found changes in the elements which characterize the current setting and the tendency of the university for adopting a diverse organizational structure. However, if the decentralization of management persists, the academic units may adopt their own structural solutions, but with no evidence of changes in the professional organization in most units. In this perspective, this thesis states that there are difficulties when incorporating innovation and flexibility to their organizational structure, which lead to improvised solutions, superposing skills through the redundancy of structures created with the same purpose or copying exogenous solutions

A Floresta Ombrófila Mista na região dos Campos Gerais do Paraná é naturalmente fragmentada, ocorrendo em forma de capões ou ao longo dos cursos d'água. Com o objetivo de caracterizar a composição e estrutura destes fragmentos e avaliar as correlações entre a distribuição das espécies e variáveis do solo de tal região, realizou-se um estudo no Parque Estadual do Guartelá, Município de Tibagi (24°39'10S e 50°15'25W). Foram alocadas 50 parcelas de 10x10m, distribuídas em capões de diferentes tamanhos e ao longo da floresta que acompanha o Rio Iapó, amostrando todos os indivíduos com altura > 3m. Foram encontrados um alto número de espécies (140) e uma elevada diversidade (H'=4,10), valores acima daqueles relatados para o domínio da Floresta Ombrófila Mista. As análises da composição e estrutura revelaram uma flora de transição entre a Floresta Ombrófila Mista e a Floresta Estacional Semidecidual, com uma maior similaridade com esta última, possivelmente influenciada pelo clima. Uma análise de correspondência canônica identificou as variáveis textura e acidez como as correlacionadas com a distribuição de abundâncias das espécies, ordenando dois grupos distintos: um formado pelas parcelas distribuídas nos capões, relacionadas fortemente à textura do solo; e outro pelas parcelas alocadas na floresta de galeria, associadas principalmente com a disponibilidade de nutrientes.

O objetivo deste trabalho foi avaliar as perdas de solo e água por erosão hídrica, em parcelas-padrão sob chuva natural, no período pós-plantio, em diferentes sistemas de manejo de florestas de eucalipto. O experimento foi instalado em Latossolo Vermelho-Amarelo, muito argiloso, relevo ondulado. As coletas de dados foram realizadas no período de outubro de 2002 a fevereiro de 2004, em eventos de chuva considerada erosiva. Os sistemas estudados foram: mata nativa; pastagem plantada; eucalipto plantado em nível; eucalipto plantado na direção do declive; eucalipto plantado na direção do declive com queima de restos culturais; e solo descoberto. Entre os sistemas florestais, o eucalipto em nível é o que mais se aproxima da mata nativa, em perdas de solo, indicando assim maior sustentabilidade desse sistema. Os maiores valores de perda de água são encontrados no sistema eucalipto plantado na direção do declive com queima de restos culturais, sugerindo que o fogo aumenta a repelência à água e diminui a taxa de infiltração de água no solo. Todos os sistemas de manejo do eucalipto estudados apresentaram perdas de solo inferiores ao limite de tolerância.

Nos últimos 30 anos não foram levadas em consideração questões metodológicas importantes relativas ao estudo da fenologia de plantas. O uso de vários métodos na amostragem e avaliação dos dados fenológicos tem levado a uma grande dificuldade na interpretação e comparação de resultados. Esse estudo tem por objetivos realizar uma revisão da literatura em fenologia de florestas tropicais, compilando informações sobre os métodos de amostragem e avaliação utilizados, e discutir as proporções em que foram utilizados e as aplicações de cada método. Nos 60 estudos avaliados, os métodos de amostragem encontrados distribuem-se da seguinte forma: trilhas (20%), transecções (18%), parcelas (15%), coletores (10%), sendo que 37% dos estudos não definiram o método de amostragem utilizado. Para avaliação fenológica foram levantados dois métodos: qualitativo, presença e ausência das fenofases (20%) e quantitativo com quantificação da intensidade das fenofases (62%), e a combinação entre métodos qualitativos e quantitativos (17%). Ao longo do tempo cresceu a preocupação com a aplicação de métodos de amostragem e de avaliação quantitativa. Entretanto, a falta de padronização no uso desses métodos, mesmo nos dias atuais, ainda se faz presente, resultando na impossibilidade de comparação adequada dos estudos. É imprescindível, portanto, a realização de estudos comparativos de métodos fenológicos com espécies arbóreas em florestas tropicais.

The creation and implementation of Brazilian labor laws during the 1930s gave rise to important political debates. The various stakeholders - the state, the bourgeoisie, and workers - each with their own social project, had forged mechanisms designed to protect their own interests. Within this framework, this article addresses the arguments regarding the Expulsion of Foreigners Act (1907), the "Dois Tercos"(Two-thirds) Act (1930), and the Unionization Act (1931). These acts provide clear evidence that the growth of state interventionism was accompanied by tensions and changes, and that the labor legislation was not simply the 'gift' of a Corporate State.
