Destino no ambiente e comportamento agronômico de atrazina em resposta a doses e níveis de palha de espécies de cobertura de solo

The use of cover crops is a fundamental strategy to the weed management in Southern Brazil. In highly infested areas, the herbicides use is increasing, which increases the costs of the crops production as well as the environmental contamination. Oat and velvet bean plants havecontrasting characteristics regarding to residues decomposition speed and the capacity to immobilize Nitrogen in the soil, providing distinct results of weeds suppression throughout the time, and therefore, requiring distinct management strategies before, during, and after the corn crop establishment. The general objective of the experiment was to evaluate the environmental dynamics of the herbicide atrazine, the corn grain yield, and the efficiency of the weed control, considering areas with distinct history regarding the use of mulching, levels of straw and rates of atrazine. For this, the experiment was carried out in two parts: in the first part, two trials with the corn crop were established, one using oat and the other using velvet bean as cover crops. The experimental design used for both field trials was randomized complete blocks arrangement with four replications. The factor A was constituted by four levels of straw (0; 0.75x; 1.5x; 3x) and the factor B was constituted by four rates of the herbicide atrazine (0; 2100; 4200; 8400 g a i. ha-1). Soil samples were collected for greenhouse trialsto determine the persistence. Atrazine leaching evaluation was performed by chromatography using samples collected over the soil profile.In the field, the weed density, the fresh and dry weight and the yield of the corn were evaluated. In the greenhouse trials, the main variables evaluated were plant height and injury caused by the herbicide toxicity. In the second part, soils with distinct covering history were sampled, and the mineralization and sorption studies, both with 14C-atrazine, were conducted in the laboratory. The experimental design was randomized complete blocks arrangement with four replications. The results from the field experiment show that the high levels of straw above ground, isolated, were not efficient to control completely the weeds, and that high levels of velvet bean`s straw decreased the corn potential yield. The greenhouse trials showed that high levels of oat straw prevent the scape of atrazine to soil, this effect of oat straw upon the herbicide availability on soil was detected up to 12 days after spraying. The half-life of atrazine sprayed over oat straw varied from 7 to 14 days after spraying, while the half-life of atrazine sprayed over velvet bean varied from 5 to 14 days after spraying. Increasing oat straw levels presents the capacity to reduce the lixiviation of atrazine in the soil profile, however, this effect was not verified when using velvet bean straw, because the herbicide was not detected in the soil profile, at 21 days after spraying. The chromatographic analysis indicate thatthe atrazine concentrates closer to the soil surface regardless of amount of straw, not being detected deeper than 8 cm in the soil. The accumulated mineralization of 14C-arazine sprayed over V. sativa is superior if compared to soils with S. cereale or non-covered soils. The sorption coefficient of atrazine is superior when sprayed over straw than over the soil.

Programa ciclovida como política de mobilidade urbana sustentável: estudo empírico na Universidade Federal do Paraná

The urban mobility has in the bicycle its symbol of the most environmentally sustainable modal of transportation of the planet, title conferred by the United Nations Organization (ONU). Nevertheless, the cities suffer with the traffic jam caused by the automobile fleet growth, what implies in a larger displacement time, injuries to the environment, to financials and to the quality of life. In order to build in a sustainable way the urban mobility, public policies are necessary to encourage the preferential usage, by the society, of the mass transit or the non-motorized type of transportation. Objecting cooperate with the public power and the civil society, this study intents to, through an analysis about the UFPR Extension Program - CICLOVIDA, propose a sustainable urban mobility public policy development, with emphasis in the bicycle´s usage. eferentially, it is discussed concepts such as Society, State and Government as well as public policies, which go in cycles to the State´s and Government´s responsibilities; and are presented the Sustainable Urban Mobility Public Policies (PPMUS) in Brazil. Also, it is debated about the transport by bicycle as an option to the sustainable mobility. Methodologically, the study is of an empiric-social nature, with the application of both qualitative and observational methods, what characterizes as an exploratory level of research, with the researcher´s involvement in the participant form, due to her acting on the Program. Regarding the research lineation, it was used the bibliographic and documental form as well as case study, by means of the nonparametric sampling by accessibility or convenience. Related to the data collection technique, it was used structured interviews with self-applied questionnaires and natural participant observation. Aligned with the research´s objective and matter, the outcome confirmed that the Extension Program CICLOVIDA of the Federal University of Paraná (UFPR) may effectively contribute in the development of a PPMUS proposal with emphasis in the bicycle usage. Thus, it was built a political proposal with a free form writing, objecting subsidize policies both institutional as public MUS through the bicycle usage and therefore, support the mobility, also contributing to the sustainability and to the public development planning.

Recrear «el verdadero lío de la vida»: programa estético y estrategia editorial detrás del ciclo ramoniano de las novelas de la nebulosa

[es] Teniendo presente que las cuatro obras que Ramón identifica en 1947 como «novelas de la nebulosa» abarcan más de veinticinco años y se definen como ciclo a posteriori, el presente artículo propone una aproximación al ciclo «nebúlico» desde la construcción discursiva metatextual que lo rodeó (en prólogos, ensayos y epistolarios) para demostrar que nació de una voluntad de Ramón de construir para sí mismo cierta imagen social de escritor y así consolidar, desde el exilio, su figura de novelista de vanguardia. [en] Only in 1947 did Ramón define as a series his “Novels of the Nebula”, a literary cycle written over twenty five years. This paper focuses on the metatextual discourse surrounding the whole series (in prologues, essays or letters). By doing so, it aims at showing how the design of the series was born from Ramón’s desire to build a certain social image of himself as an avant-garde writer.

DESAFIOS E REFLEXÕES NA IMPLANTAÇÃO DE UM PROGRAMA DE EDUCAÇÃO ALIMENTAR E NUTRICIONAL (EAN) EM INDIVÍDUOS COM EXCESSO DE PESO

Objetivo: Relatar a experiência das atividades de educação alimentar e nutricional (EAN) desenvolvidas em pacientes com sobrepeso e obesidade. Síntese de dados: Realizaramse sessões de educação alimentar e nutricional (EAN) com pacientes com sobrepeso e obesidade graus I e II atendidos no ambulatório do Hospital Universitário da Universidade Federal de Juiz de Fora (HU/UFJF), integrantes do projeto de extensão “Saúde na Balança”. As sessões ocorreram em grupo, semanalmente no 1º mês, quinzenalmente no 2º e 3º mês e mensalmente até o 6º mês, no período de setembro de 2012 a setembro de 2013. Durante um ano de atividades, foram realizados 4 grupos, com um total de 46 integrantes, que aceitaram participar das sessões. Nestas, foram abordados temas em nutrição que apoiavam o atendimento individual. A equipe identificou que local, horário, periodicidade das sessões, disponibilidade de tempo e falta de recursos financeiros eram fatores que influenciavam a adesão do paciente ao tratamento, sendo alguns deles modificados, já se observando melhora da adesão no último grupo. Entretanto, ainda foram registradas 17 desistências. Com o autorrelato dos pacientes, foi possível perceber mudanças positivas nos hábitos alimentares e na forma de se relacionar com a obesidade e as comorbidades associadas. Conclusão: No decorrer das atividades, criou-se vínculo entre equipe e participantes, permitindo identificação de demandas e de formas efetivas de atuação nos grupos, demonstrando que a EAN auxilia a abordagem individual, na medida em que permite troca de experiências e informações, ampliando o poder de escolha por hábitos de vida saudáveis.

Contribuições da inserção musical para a qualidade de vida no trabalho em ambiente laboral fabril

The present thesis aimed at understanding how the insertion of music in the work environment contributes to achieving Quality of Work Life. - QWL, under the perspective of biopsychosocial and organizational well-being. As to music insertion we considered the theoretical-empirical perception about how music is inserted at work and its functions on such place. The context where the study was taken was the manufacturing area of a major textile company, located in Natal, state of Rio Grande do Norte, Brazil, in which music is used during labor activities. The only study case was the research strategy adopted, with exploratory and descriptive purposes. The primary data were collected through the focus group technique, applied to the collaborator in the manufacturing sector. The semi-structured interview was done as a complementary tool, directed to the supervisor in that sector. Respecting the theoretical saturation criterion, we formed four focus groups, each one composed of eight members randomly selected, among the seventy-six collaborators in the sector. The data were analyzed qualitatively, through the content analysis technique, more specifically the category analysis. We identified twenty-eight QWL attributes. Six of them were found present in the four focus groups and in the interview. Among these ones, the attribute of Interpersonal Relationship at Work, contemplating the Psychological and Organizational dimensions, was the only one anticipated in four out of fifteen theoretical models here listed. The attribute Music at Work Environment could be inserted in the four QWL dimensions, highlighting the power and relevance of this attribute for the research participants. The way music has been inserted in the labor environment contributes to promoting well-being at work, which goes against theoretical conceptions, especially when it comes to musical genre. We identified nine functions of music at work, among which, Improving Work Conditions, Improving Interpersonal Relationship at Work and Favoring Motivation for Work had to be emphasized for being associated to three QWL attributes. In the total, we highlighted seven associations. The most affected QWL dimension through the insertion of music at work was the Psychological one, followed by the Organizational one. We conclude that music insertion provides biological, social and, above all, psychological and organizational well-being to the contributors, thus contributing to obtaining QWL at the labor environment researched. However, we should consider the context and proceed to periodical plans and adjustments in the way of music insertion so as to avoid health and well-being problems to those people at work

Fatores de longevidade do programa Central do Cidadão no Rio Grande do Norte

The public management reform in Brazil, since 1995, provoked new experiences in public administration. Among the new models of public service the one-stop shopping has distinguished and was adopted at Rio Grande do Norte with the Citizens Center Program. The one-stop shopping assembles in the same place many public services with appropriate structure, enabled human resources and citizens focus processes. The goal of this research was understand how citizens focus processes help to explain Citizens Center Program s longevity. It was made a case study and the research tools were applied with Citizen Center Programs workers and citizen-users at South Unit of Citizen Center Program placed at Via Direta Mall, Natal. The major contributions for Citizen Center Program s longevity were imputed to Basic Operation Processes. The most spoken features in Citizen Center Program mentioned were quality, efficiency, celerity e personal appearance, what demonstrate concern and care with citizen-users. Worker s personal appearance, accommodation, celerity, politeness and attending capacity planning were high evaluated by citizen-users revealing the wisely choice of use a large quality concept and citizenship concept in public administration. Citizen-users also pointed the necessity of refine and enlarge the communication ways that form an essential mechanism to public citizen focus administration. Not ignoring the policy aspect citizen focus processes were noticed like especial management actions that make easier citizen s activities and public service access, what generate satisfaction to citizen-users. It s possible to conclude that the high level approving evaluation of Citizen Center Program consolidates it an especial public policy that serves citizen s necessities e create appropriate legitimacy conditions of the public policy making harder the choice of ending the policy even in more fragile moments strongly contributing for its longevity

Os programas de incentivo à cultura e o processo de fomento às organizações culturais no Rio Grande do Norte: o caso da Casa da Ribeira em Natal

Since the emergence of the first demands for actions that were intended to give greater attention to culture in Brazil, came the first discussions which concerned the way the Brazilian government could have a positive influence in encouraging the culture, as is its interaction with the actors interested and involved with the cause. During the military dictatorship, there were programs which relied on the direct participation of the State to ensure that right, from the viewpoint of its support and implementation of public resources in developing the "cultural product" to be brought to society in its various forms of expression - all this, funded by the government. It is an example of "EMBRAFILMES" and "Projeto Seis e Meia", continued until the present day in some regions of the country, though maintained by entities not directly connected with the administration or the government. However, it was from the period of democratization and the end of the dictatorship that the Brazilian government began to look at the different culture, under its guarantee to the society. Came the first incentive laws, led by "Lei Sarney" Nº 7.505/86, which was culture as a segment which could receive foreign assistance in order to assist the government in fulfilling its public duty. After Collor era and the end of the embargo through the encouragement of culture incentive laws, consolidated the incentive model proposed in advance of Culture "Lei Sarney" and the federal laws, state and local regimentares as close to this action. This applies to the Rouanet Law (Lei Rouanet), Câmara Cascudo Law (Lei Câmara Cascudo) and Djalma Maranhão Cultural Incentive Law (Lei de Incentivo à Cultura Djalma Maranhão), existing in Natal and Rio Grande do Norte. Since then, business entities could help groups and cultural organizations to keep their work from the political sponsorship under control and regiment through the Brazilian state in the form of their Cultural Incentive Law. This framework has contributed to the strengthening of NGOs and with the consolidation of these institutions as the linchpin of Republican guaranteeing the right to access to culture, but corporate social responsibility was the one who took off in the segment treated here, through the actions of Responsibility Cultural enterprises arising from the Cultural Organizations. Therefore, in the face of this discourse, this study ascertains the process of encouraging the Culture in Rio Grande do Norte from the Deviant Case Analysis at the Casa da Ribeira, the main Cultural Organization that operates, focused action in Natal in order to assess the relationships established between the same entity and the institutions which are entitled to maintain the process of encouraging treated in this study - Enterprise, from the viewpoint of corporate sponsorship and Cultural Responsibility and State in the form of the Laws Incentive Funds and Public Culture Incentive
