Um Estudo de Politicas e Práticas do uso do GNV no transporte público urbano do Brasil

The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, considering the PROCONVE rules. Due to the need to diversify the matrix in order to avoid energetic dependence and due to strict pollution control, it has increased in the Brazilian market the number of vehicles converted to the use of NGV. The recent regulation of the PROCONVE, determining that the converted engines with kits should be submitted to emission testing, comes to reinforce the necessity of the proposed development. Therefore, if we can obtain kits with the characteristics already described, we can reach a major trust in the market and obtain an increase acceptance of the vehicle conversion for NGV. The use of natural gas as vehicle fuel presents several advantages in relation to liquid fuels. It is a vehicle fuel with fewer indexes of emissions when compared to diesel; their combustion gases are less harmful, with a major level of safety than liquid fuels and the market price is quite competitive. The preoccupation that emerges, and the motivation of this project, is to know which are the main justifications for such technology, well accepted in other countries, with a low index or emission, with a high level of safety, where its maintenance becomes low, reminding that for this it is necessary that this technology has to be used properly, and once available in the market will not motivate interest in the urban transportation companies in Brazil, in research centers in general. Therefore this project exists to show the society in a general way the current vision of the main governmental factors, of the national research centers and of the private companies concerning the use of natural gas vehicles in urban transport vehicles, in order to give a major reliability to the population as well as to motivate national market competitiveness with a low cost and reliable product and to enrich the national technology

Representações discursivas no discurso político. Não me fiz sigla e legenda por acaso : o discurso de renúncia do senador Antonio Carlos Magalhães (30/05/2001)

O objetivo deste trabalho é investigar como as representações discursivas do locutor e dos alocutários são construídas no discurso de renúncia ao mandato de senador, proferido por Antonio Carlos Magalhães (ACM), na 62ª sessão deliberativa ordinária, em 30/5/2001. A perspectiva teórica que adotamos situa-se no campo da Linguística do Texto, com foco na abordagem da Análise Textual dos Discursos ATD (Adam, 2011). A noção de representação discursiva apresentada pela ATD constitui um dos aspectos da dimensão semântica do texto e baseia-se parcialmente nos trabalhos de Grize sobre a esquematização (1990, 1996). Complementamos as categorias de análise com contribuições que nos permitem detalhar a expressão linguística, textual, e discursiva das representações discursivas (Neves, 2006; Castilho 2010; Rodrigues, Passeggi, Silva Neto, 2010; Rodrigues et al. 2012; Passeggi, 2012). O enfoque metodológico é qualitativo, descritivo e interpretativista (Minayo, 1994; Trivinõs; 1987; Gil, 2002). Os procedimentos de análise utilizam as categorias semânticas de referenciação, predicação, modificação (de referentes e predicações), localização espacial e temporal, conexão e comparação. A representação discursiva do locutor (ACM) é constituída pelo conjunto de representações mais específicas, expressas nas referenciações e nas suas modificações: vítima; político; sigla; baiano, nordestino; presidente do senado; senador confiante; condenado. ACM, como protagonista, assume sempre a sua voz no discurso, manifesta seus pontos de vista e posiciona-se como sujeito ativo, consciente da importância do seu papel político e social, que o torna alvo e vítima das ações dos adversários. Complementando essa referenciação, as predicações e suas modificações se expressam através de verbos de ação, em especial, verbos na 1ª pessoa do singular que marcam o tempo presente, real e conclusivo de ações que constroem um cenário positivo para si mesmo. A localização temporal e espacial, indica as ações realizadas pelos participantes nas diversas etapas temporais selecionadas pelo texto, articuladas a três espaços principais: o Senado Federal, o Brasil e, naturalmente, a Bahia. Por sua vez, conectores adversativos (sobretudo, mas ), explicativos e condicionais acompanham e estruturam o ritmo argumentativo do discurso de renúncia de ACM

Caracterização in situ e diversidade genética de algodoeiros mocós (Gossypium hissutum raça marie galante) da Região Nordeste do Brasil

Brazil is one of the major centers of diversity for polyploid cotton plants; these plants belong to the genus Gossypium, which has three known species: G. hirsutum, G. barbadense and G. mustelinum. The Northeast is the only region where the three species occur, the last group being endemic. Northeast s cotton plants can be important sources of variability for genetic breeding. It is believed that great part of local diversity is being lost, due to economic, political, cultural and agricultural problems. In an attempt to mitigate this loss and delineate conservation strategies it is necessary to know how the species are found where they occur. The objective was to characterize and determine how plants are maintained in situ in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte and Paraíba at the beginning of the XXI century. The in situ characterization of G. hirsutum and G. barbadense was conducted through structured interviews with the cotton plants owners and through the analysis of the environment. The data were collected during expeditions undertaken between the years 2004 to 2005. Twenty-two plants were collected in the state of Paraíba, forty-four in the state of Rio Grande do Norte, one hundred and forty-six in the state of Ceará, forty in the state of Maranhão and ninety-one plants in the state of Piauí. All plants collected in the states of Paraíba and Rio Grande do Norte belonged to moco type. Moco cotton plants also predominated in the other states, representing 92%, 62% and 78% of plants collected in Ceará, Piauí and Maranhão, respectively. The other cotton plants collected belong to the species G. barbadense. The cotton plants were found in situ as dooryard plants, roads side, feral populations, cultivation or local varieties. Great part were dooryard plants (45.2%), being major in Piauí and Maranhão. Cultivation predominated in Ceará; in Rio Grande do Norte feral populations were the most frequent and, in Paraíba, local varieties. The maintenance of moco plants is related, mainly, to the phytotherapic domestic use (20.9%) and to confection of lamp wicks (29.7%). Few inhabitants in Paraíba, Rio Grande do Norte, Piauí and none in Maranhão used harvest the plants, storage the seeds or gin; however, in Ceará, 40.5% of owners affirmed that they harvested and commercialized the fiber. It was found that the maintenance of species is dependent of the fragile cultural habits of local inhabitants, therefore the maintenance in situ is not a suitable way to conservation of genetic resources. The efforts must be directed to the continuity of collections, maintenance and characterization ex situ

Caracterização genética e in situ de Gossypium barbadense na região norte do Brasil

Brazil has been considered one of the diversity centers of Gossypium barbadense species. It is believed that a relatively big erosion genetic process occurs with the species, due to economic, cultural and agricultural problems. A local diagnostic about species situation is the first step for reducing the diversity loss and establishing conservation strategies in situ. This research aimed the identification of the presence of Gossypium populations, characterization, determination of the main risks and collection of the accesses to store in germoplam banks, in Para and Amapa States. Expeditions were conducted in November 2004. An interview was carried out with the plant proprietor for characterizing in situ of G. barbadense species and of the environment where the plants were inserted. On hundred seventy nine plants in 22 municipal districts were collected in Para State and 117 plants in nine municipal districts in Amapa State. The majority of plants belong to G. barbadense species (98% in Amapa and 94% in Para). Plants occur in back yards, beside roads and spontaneously. That ones from back yards were more abundant (97% in Amapa and 95% in Para) and maintained as medicinal plants as the principal reason. Plants in natural environments in both states evaluated were not found, therefore, the creation of reserves and the application of others conventional methods of maintenance in situ are not applicable. The plant proprietors do not use to store or process seeds. Seed storage was reported as a practice by only 1% of the plant proprietors from Para and 11% from Amapa. The most plants collected were from two to three years of age (58% in Amapa and 93% in Para). As conclusions G. barbadense is the species most spread in the two studied states and are found in back yards. In Amapa State the botanical variety barbadense or Quebradinho is predominant, whereas in Para State the predominant variety is brasiliense or Rim-de-boi. Adequate conservation of thestudied species must be carried out in germoplasm collections maintained ex situ

A percepção dos docentes da UFRN sobre o programa de apoio a planos de reestruturação e ampliação das universidades federais - REUNI

In recent decades higher education in Brazil has gone through several changes. The Programa de Reestruturação e Expansão das Universidades Federais REUNI has been the greatest overhaul performed by the government in public universities in the last years. REUNI is presented as the biggest reform in tertiary education in contemporary times, having as the main goal a gradual increase in the average rate of conclusion in live learning graduation courses up to 90%, as well as a rate expansion of graduating students in face to face classes per professor. This research aims at studying the perception of professors from UFRN concerning the REUNI program in execution from 2008 until 2012. The study seeks to understand how professors evaluate the program and what the dimensions that most influence in this evaluation are. The study made use of a research tool (survey) which was sent through the internal system of the university, SIGAdmin, to all professors of superior teaching from UFRN. The answers generated by the survey were processed using SPSS statistical software (Statistical Package for Social Science). Factorial Analysis and Multiple Linear Regression were used as an analysis technique. 180 answers were obtained, reaching all UFRN Centers and some academic units, as well as some campuses in the countryside of the state. Through the research was possible to analyze how professors from UFRN perceive the REUNI program implemented in the institution. The results point to the program approval by the professors. Statistical tests showed that the average values obtained in the Centers and academic units are basically the same. It was demonstrated that the extent that most influenced in the answers is linked to practical outcomes of the program, whereas the knowledge of REUNI goals was the least that impacted on the marks given to the program. Another dimension which influenced the perception of professors relates to the influence of REUNI in their activities. It was observed that professors from UFRN don t see REUNI as an impediment to them

Adolescentes e jovens e suas bases de apoio :relações de amizade como suporte social no enfrentamento à violência

The purpose of this work is to map the family and community social supports for adolescents and young students from Bom Pastor Distric, West Zone of Natal/RN, as well as to describe how such resources are used by these individuaIs in that community. Social support refers not only to formal activities or organizations, but also to spontaneous or informal forms of support - friendship and solidarity nets available in the community, affective relations that are meaningful in the lives of children and young people. Our discussion is based on a research performed with 382 adolescents and young students from Jean Mermoz Public School (students from 5th to 11th grades, aged 13 to 14). We emphasized the situations of violence derived from family or community spheres faced by these students. In relation to this specific aspect, we observed the participants more frequently look for help from the informal social supports, mostly from their friends, which indicates that the formal ones are not considered to be effective instruments for social assistance. The search for informal social supports shows the relations informally established in the streets (for instance when they look for help from friends, rei atives or neighbors) have more effect and play an important role in which there are values and affections exchange. Thinking the strengthening of these social links is of extreme importance and leads to the weakening of the hegemonic logics focused on the production of subjects as private identities, and to the amplification of an ethics committed to the disassembly of a sociability anchored to fear, impotence, intolerance, discrimination, and reduction of spaces for circulating and confronting mechanisms of social exclusion. It is crucial that we concentrate our attention to building friendship as a system of reciprocity and affective exchanges, as a space for political actions and production of forms of lives that are potent against social anesthesia

Entre a hegemonia e a polissemia: a Política de Educação e Desenvolvimento para o SUS no contexto do Brasil contemporâneo

The proposal of the Unified Health System Policy (SUS) has been considered one of the most democratic public policies in Brazil. In spite of this, its implementation in a context of social inequalities has demanded significant efforts. From a socio-constructionist perspective on social psychology, the study focused on the National Policy for Permanent Education in Health for the Unified Health System (SUS), launched by the Brazilian government in 2004, as an additional effort to improve practices and accomplish the effective implementation of the principles and guidelines of the Policy. Considering the process of permanent interdependencies between these propositions and the socio-political and cultural context, the study aimed to identify the discursive constructions articulated in the National Policy for Permanent Education in Health for the Unified Health System (SUS) and how they fit into the existing power relations of ongoing Brazilian socio-political context. Subject positionings and action orientation offered to different social actors by these discursive constructions and the kind of practices allowed were also explored, as well as the implementation of the proposal in Rio Grande do Norte state and how this process was perceived by the people involved. The information produced by documental analyses, participant observation and interviews was analyzed as proposed by Institutional Ethnography. It evidenced the inter-relations between the practices of different social actors, the conditions available for those practices and the interests and power relations involved. Discontinuities on public policies in Brazil and the tendency to prioritize institutional and personal interests, in detriment of collective processes of social transformation, were some of obstacles highlighted by participants. The hegemony of the medical model and the individualistic and curative intervention practices that the model elicits were also emphasized as one of the drawbacks of the ongoing system. Facing these challenges, reflexivity and dialogism appear as strategies for a transformative action, making possible the denaturalization of ongoing practices, as well as the values and tenets supporting them

Instrumentalidade do serviço social na previdência social no Brasil contemporâneo

In the sociability of the capital, the challenges to the consolidation of social security as a public policy become expressive, which has implications for social security services, particularly for Social Works who works for the security and fulfillment of social rights. Therefore, in this context of denial of these rights becomes relevant the work of social worker, as a professional committed to the ethical-political project and the Matrix Theory and Methodology of Social work, which potentiate the action able to establish professional articulated strategies for the strengthening of collective struggles for equality in society. Thus, this study examines the instrumentality of social work in the contemporary world and its contribution to the realization of rights. For this, we conducted a literature review, using authors dealing with the issue, as Behring (2008), Boschetti (2003), Mota (1995), Guerra (2007) among others, as well as documentary research through laws, decrees, instructions Normative, Internal Guidelines, and especially the analysis of the Matrix itself of Social Work in welfare. We use also of paramount importance to our analysis - the field research, using techniques such as semi-structured interview and questionnaire. The research enables the identification of important aspects of the subject studied, as the understanding of professionals about the instrumentality of Social Works in its ethical-political aspects, both theoretical and methodological and technicaloperative. The demands made by the managers for the profession on the sociooccupational have extrapolated the powers and duties of the Law Regulating the Profession and the Matrix of Social Work in welfare. The subjects of this study emphasize the role of social category of the National Institute of Social Security and the Federal Council of Social Service in defense of Social Works. The knowledge of social and institutional framework is critical to building control strategies that strengthen social security and public policy, the guarantor of social rights for workers in Brazil

Serviço Social Audit Saúde no SUS/RN: projeto ético político profissional e de reforma sanitária

Health policies in Brazil, the decentralization of SUS management responsibilities for the three spheres of government has driven the creation and regulation of the audits of health services in the National Audit Office, this is a trend of neoliberal policies imposed by international bodies like the World Bank and IMF to peripheral countries characterized by productive restructuring and reforming the state focuses on the presence of two competing projects in the area of health: Health Sector Reform Project which is based on the democratic rule of law with the assumption of health as social right and duty of the State in defending the extension of the conquest of rights and democratization of access to health care guaranteed through the public financing strategies and the effective decentralization of decisions pervaded by social control and privatized Health Project which is based on the state minimum, with a reduction in social spending or in partnerships and privatization, stronger nonprofit sector, subject to capitalist interests, is made effective through strategies targeting health policy and refilantropização actions. In this context, the present study is an analysis on the work of social audits of public health in infants from a qualitative and quantitative approach, embodied by the critical method of dialectical Marxist social theory that enabled us to unveil the characterization, the demands, challenges and outline the profile of Social Work in teams inserted audits of SUS in RN, but also provided evidence to demonstrate the prospects and possibilities of this area of activity of social workers. It was also found that through the audit work that the state fulfill its role as bureaucratic and regulator of health services with efficiency, effectiveness and economy. Yet, paradoxically, the audits of SUS may provide a vehicle for enforcing rights and ensuring the fundamental principles contained in the project of health reform, because it can be configured in a space of political struggle as representing a new field of knowledge production that needs to be appropriate for a theoretical critic able to redirect the social interests in favor of the user. From this perspective, it is concluded that the work of social audits of public health in infants despite the social relevance that prints, as they constitute an activity study of reality and its transformation proposition requires a transformative political action guided the discussion Marxist theory holds that the ethical project professional politician of Social Work

A organização sindical dos assistentes sociais no Brasil: dilemas e desafios contemporâneos

This paper discusses the dilemmas and challenges of the union of social workers in contemporary Brazil. The study is supported by the theme in a literature search, especially productions that deal with the trade union movement of workers in the brazilian reality, as well as on field research, which consisted of interviews with national trade union leaders of the CUT and CONLUTA as also representatives of national organizations representing the professional category of social workers, notably CFESS, ABEPSS ENESSO and a labor union and the national category, FENAS. The analysis of the object is oriented in the perspective of totality, considering its founding and contradictory aspects of the current socio-historical dynamics. The inflections occurred in the razilian Labor Movement in the early 1990s, during which the offensive of capital, characterized by the fusion of flexible accumulation and the dictates of neoliberal policy is established in the country, caused a profound shock in life and organization of the class working. The major repercussions of this process are evident today in the form of defensive organization of trade union struggles, notably fragile and fragmented. In the case of the category of social workers is symptomatic of the political backlash, experienced the process of reopening their unions and the creation of FENAS. This definition, part of the analysis that considers more strategic perspective of class organization, corporate antiunionism of the mass of the 1980s, built, largely, by category and expressed by the extinction of their union and unification to the broader struggles of workers with transition to unionization by industry. Given this reality, we analyze the performance of the political perspectives of the brazilian labor movement, from the characterization of organizational arrangements for trade union struggles and situate this process, the motion to reopen union of social workers, from the emergence of FENAS. Therefore, we aimed to identify the particular and the ideological and political perspectives that make up the dilemma of the trade union movement from this reopening, as corresponds to a political trend, largely, overcome within the brazilian social work

Entendendo as interações entre povos pesqueiros, manguezal e área protegida: RDS estadual Ponta do Tubarão (RN, Brasil)

The mangrove ecosystem has a great importance to maintaining marine biodiversity, and to the livelihoods of communities living around it. Despite its importance, many mangrove areas have been extensively cleared and converted to other uses. There are few places where communities can retain their traditional uses of mangrove. A good example of conservation of traditional costumes are the fishing communities of the Sustainable Development Reserve (Reserva de Desenvolvimento Sustentável RDS) Ponta do Tubarão. The creation of the reserve came from the own population, and the devastation of a mangrove area, which would be destined for activity shrimp, was one of the reasons that led the population to ask authorities the establishment of a legally protected area. Thus, this study aimed to investigate the environmental perception of the fishing communities of RDS Ponta do Tubarão with respect to the mangroves in a biological, ecological and social perspective as well as evaluate the influence of the reserve in the mangrove conservation and quality of life. To meet objectives of this study was required the appropriation of some method and approaches of ethnosciences and environmental perception. Data were collected through direct observation, and semi-structured interviews. Through content analysis found that the population has a strong dependence on the mangrove ecosystem, as well as provides a good ecological knowledge of ecosystem functions. It was also found that the reservation has a good performance in the conservation of the mangroves; however, need to outline strategies to conciliate both the biological and cultural conservation.

A incorporação de preceitos ambientais no sistema de gestão de resíduos sólidos do município de João Câmara - RN Brasil

The reality points to the global environmental sustainability as the only viable option for addressing the crisis at hand. The move towards sustainability calls for the generation / evaluation systems in their direction, through the incorporation of environmental requirements and in line with the National Policy on Solid Waste. Therefore, the proposed research supports the importance of social and environmental vision, complementing the technical view, the system for management of solid waste from East London, which is a municipality that has a system whose inadequacies are configured in environmental risk and health. Therefore, by observing, applying the model of sustainability indicators and content analysis of interviews, this research proposes to investigate the principles of sustainability and social participation are presented and what is the perception of risk about the inadequacies in the system. The results confirmed the hypotheses of the study and draw a picture of worrying data, such as very unfavorable indicators of sustainability, lack of channels of participation, uncommitted investments with the management system, devaluation of the collector of waste and differing perceptions about the risk by making actors act in isolation. This worrying situation is eased by the appearance of a series of elements are configured as opportunities for the integration of environmental principles in the system. And despite the inability of managers to participate in the research system, yet it behaves as an opportunity to implement public policies in the area of solid waste such as: the preparation of the municipal waste, the institutionalization of selective collection and organization of cooperative with the support of companies present in the city and educational institutions as the Federal Institute. The research is an opportunity for the implementation of policies in the area of solid waste and will collaborate with the building instruments for the quality of life of residents, for the socioeconomic conditions of collectors and the move towards a sustainable society

Comércio internacional e meio ambiente: estímulo à produção sustentável ou mero protecionismo comercial a posição do Brasil em dois casos de litígio

The World Trade Organization (WTO) was established in 1994 as a result of the Uruguay Round, and has as its principal aim advocate for the maintenance of free trade between nations. The preamble of its Constitutive Agreement specifically cites as an institution the goal of achieving sustainable development and the pursuit of protecting and preserving the environment, bringing into the sphere of world trade the idea that concern for the environmental cause is not restricted only the group of environmentalists, but rather has entered the economic landscape in a way not only ideological, but also pragmatic. The General Agreement on Tariffs and Trade (GATT) 1947, part of the GATT 1994, contains a device that allows the adoption of trade restrictive measures, provided that such measures aimed at protecting the environment - Article XX. The Settlement Body (DSB) is part of the WTO and acts in dissolving disputes between the countries motivated by trade. It examines two cases where countries have imposed restrictive trade measures with environmental justification. The first case was closed in 1996, with award of damages given to Brazil, on the breakdown of U.S. environmental legislation imposed on imported gasoline from Brazil - and the second, begun in 2005 and closed in 2007, coming out victorious again Brazil is on the import ban on retreaded tires to Brazil. The objective is to answer the question: how the environment is treated in the midst of trade discussions - which is aimed at its protection or its use with economic objectives in disguise? For the preparation of this work, extensive documentary research was undertaken with the virtual site of the WTO to review the entire production of legal cases and subsequent analysis of the key issue for the work, and literature of authors who have studied the tense relationship between trade international environment. The first case, it could be seen that the political movement performed by the U.S. with the aim of achieving acceptable standards of air quality was an institutional effort to ensure the quality of air, and thus would be inappropriate to say that the regulation of gasoline was merely a disguised trade barrier.However, a careful analysis of the implementation and operation of gasoline regulation may reveal intentions disguised trade and U.S. environmental argument did not hold. The weight of this environment was relegated, since there were clearly outside interests to the environmental cause. The second case, it was realized that, despite clear attempts by the EC to promote ecological dumping, send when brought to Brazil, supposedly a country with weaker environmental structure on surveillance, a residue that, pursuant to internal policies, as could not be sent to their own landfills, the Brazilian discourse remained focused on the environmental cause, and this sort there was the existence of disguised trade barriers, but of importance, at least a priori, the discussion of foreign forces on the environment environment because there is no way to legally justify the reversal of the total understanding of the first judging body, the sight of all the arguments presented by Brazil and the nonsubmission of new facts upon appeal. Still, quite heartening to reflect on the role of trade liberalization on the environment in general, because, while they do not reach a definitive conclusion will reveal positions in both directions, both for and against, the that only adds to the discussions and makes this a very fertile topic for future research
