Os rostos da pobreza brasileira: análise crítica dos discursos do governo federal, da Veja e da Cufa

Brazilian constitution says that all Brazilians have basic survival rights such as education, sanitation and food, but these basic rights are luxury for some. So, thinking about this, this paper aims to develop a critical analysis about the (re)production of the discourse on poverty, and consequently on the poor, given by the federal government, through the official website of the program Brazil Without Poverty (Brasil Sem Pobreza), the media, represented by Veja magazine, and by those who affirm to be representatives of the poor; like the Single Central Slums (Central Única das Favelas CUFA). Our aim is to present a critical reflection on the discourses about the poverty in the voices of the government, Veja magazine (media representative) and CUFA (poor representative) and their contribution to the development of the meanings of the theme in Brazilian society. In order to do so, we have identified categories based upon Bajoit (2006a) to classify which the author calls faces of poverty . We have used the Sociological and Communicational Discourse Approach (ASCD) as developed by Pedrosa (2012a, 2012b, 2012c), within the Critical Discourse Analysis as theoretical apparatus, and also the studies in which the ASCD is built upon such as Sociology for Social Change (BAJOIT, 2006), the Cultural Studies (HALL, 2005), and the Functional Systemic Linguistic, especially the Evaluating System (MARTHIN & WHITE, 2005, VIAN JR et al, 2011). Thus, the discourse on poverty or on fighting poverty, extracted from news, chronicles and other genres of the mentioned vehicles, are taken as object of study to understand identities that are created and renewed on poverty and on the Brazilian poor, as their dependence on the government and civil society, their exploitation by the economy, and even the media that sometimes features them as delinquent

O Planejamento estratégico sem plano: ícones urbanos e dinâmica imobiliária em Natal

The model of strategic city planning is applied to Latin American and Brazilian cities since the 1990s. Notwithstanding, in many cities, the production of space has not followed the international model stricto sensu, but a variation of the model, here called, strategic city planning without a plan or peripheral (or yet incomplete) urban entrepreneurialism . This seeks to build city attributes in order to qualify cities for the competitive international and/or regional markets. This includes the production of iconic buildings and structures, here called urban icons. They rapidly become symbols in the contemporary city landscape, facilitating the promotions of the city for tourism and business. This also helps produce charismatic leaderships. However, what it does best is to promote real estate development. This dissertation seeks to understand the role of iconic buildings in the promotion of real estate business in Natal, especially how it helps to fuel prices in the market. The research is done by use of interviews with civil servants and private entrepreneurs related to real estate business

Por uma "cidade nova": apropriação e uso do solo urbano no terceiro bairro de Natal (1901-1929)

This research aimed to analyze the forms of ownership and use of urban land in Cidade Nova, third official neighborhood of Natal (Rio Grande do Norte), between 1901 and 1929. During this period, the city and state authorities began an urban renewal, trying to transform the city, represent it as a new, modernized, able to track the progress and the new political condition of the capital of a republican state. It is observed in Cidade Nova construction of a new material and symbolic territory: the area that was once occupied by huts built by refugees of drought and some summer houses, was, from 1901, transformed, scanned through a urban plan. In Natal various municipal resolutions published between 1901-1929, showed the desires of the group leader to build on Cidade Nova neighborhood a delightful, modernized its structures to reflect the new political condition of the capital of a republican state. The analyzes of the edicts of the materials published in the newspapers A Republica and Diário do Natal, and especially the study of letters of aforamento, demonstrated how many laws were not enforced or resignified, highlighting the existing continuities. Thus, throughout the paper aims to examine how this territory was occupied and used by its inhabitants, such as the granting of land in aforamento may exemplify this practice and noncompliance and how the land was used to consolidate relations of influence and power. After all, the values given to a space, turning it into territory, resulting from the social dimension of this space, in other words, the social categories that use it. Cannot be, therefore, analyze the ways of appropriation and use of urban land in the third neighborhood of Natal without studying individuals who appropriated and used this territory. The study of the allocation of extant aforamentos of land located in this neighborhood process demonstrated the formation of a specific type of market that were at stake not only economic exchanges, but also, and above all symbolic exchanges involving political and social capital. The analysis of such personnel developed market with the lands of Cidade Nova may indicate the existing relations of power between state government, Stewardship and tenants, providing a significant example of this modernization Natal early twentieth century process, guided by a more wealthy group and influential and characterized by limited social changes

Análise de células t regulatórias foxp3+no líquen plano oral

T regulatory cells have the function of controlling immune responses and maintaining self-tolerance. The FoxP3 has been considered the most specific marker for Treg cells. The aiming of this paper was to evaluate the immunoexpression of FoxP3 in the inflammatory infiltrate from oral lichen planus (OLP) and to compare it with the infiltrate in fibrous inflammatory hyperplasia (FIH) and then, between reticular and erosive forms of OLP. The samples were composed by 32 cases of OLP (17 reticular and 15 erosive) beyond 10 cases of FIH that were submitted to immunohistochemistry staining for FoxP3. Localization of the staining was classified in underepithelial and intraepithelial and the amount of FoxP3+ cells was evaluated through cells counting in 10 consecutive fields, at 400x power magnification. The values were expressed in mean ± standart deviation, and submitted to statistical tests with 5% of significance level. It was observed a statistical significant difference in the amount of FoxP3+ Treg cells between the two combined forms of OLP (1,6 ± 2,2) and the FIH (0,5 ±0,4) (P<0,05). This maybe could be explained by immunological mechanism of OLP, which involves a permanent antigenic induction likely with consequent perpetuation of lesion, eliciting the proliferation and constant recruitment of Treg cells. Otherwise, FIH presents a different etiopathogenesis, in which there is also generation of a variable inflammatory infiltrate, however qualitatively distinct from that seen in OLP. The erosive form of OLP exhibited a greater number (1,7 ± 2,4) of FoxP3+ Treg cells than reticular form (1,5 ± 2,1). These alterations could have relation with the great disease activity verified in erosive OLP, or also, with abnormalities in the regulatory function of Treg cells that could cause the increase observed. Considering the capacity already well established in the literature, both about Treg cells in modulating immune responses, as in the oral mucosa in showing great potential for regeneration, it is suggested that the possibility of development and implantation of immunotherapeutic strategies that regulate the frequency and function of these cells, may help in future treatment of immune-mediated inflammatory diseases such as OLP

Estudo clínico e níveis de ansiedade em uma série de casos de líquen plano oral

Oral Lichen Planus (OLP) is a relatively common, cronic inflammatory disease. Its etiopathogenesis is no completely understood and several factors have proposed in attempt to explain the appearance, variety of clinical manifestations and periods of exacerbation and remission of the symptons of the lesions. The objective of the present study was to assess the presence of local factors, systemic diseases and levels of anxiety in patients with OLP, investigating their association with the clinical characteristics of the lesions. The sample consisted of 37 patients with histopathologically confirmed OLP that were submitted to a clinical exam to evaluate the presence of smoking habits, consumption of alcoholic beverages, diabetes mellitus, hypertension and hepatitis C virus (HCV) infection. The existence of skin lesions, as well as the time course, clinical form, symptomatology, number and location of the oral lesions were also registered. The trait anxiety was measured by Spielberger s Stai-Trait Anxiety Inventory (STAI), and to associate the variables we used the chi-square or Fisher s exact test. It was observed that females were the most affected (75%) and the mean age of the patients was 53,3 years. Most cases were non-smoker (97,3%) and none was drinker. Diabetes mellitus and hypertension were present in 10,8% e 16,2% of the sample, respectively and only one patient was HCV-seropositive (2,7%). Moderate levels of anxiety were seen in most cases (78,4%) and 21,6% had elevated levels. The oral lesions persisted in 95% of the cases for a period of 6 months to 13 years. The erosive form was the most prevalent (57,1%) and symptons were reported by 45,7% of the patients. Multiple lesions were frequent (60%), affecting mainly the buccal mucosa, followed by gums e tongue. There was no significant association of the presence of diabetes mellitus, hypertension and levels of anxiety with the clinical form or symptomatology of the oral lesions (p>0,005), despite a trend in patients with hypertension to have erosive lesions. It was concluded that, in the sample studied, moderate levels of anxiety were commonly observed, and the HCV infection apparently is not related to the onset of the OLP. In this study, the presence of diabetes mellitus, hypertension and levels of anxiety seem not to be associated with the clinical characteristics of the lesions of OLP

Análise da resposta th17 em líquen plano oral

Th17 cells have been strongly associated with the pathogenesis of several autoimmune and inflammatory diseases. IL-17 and IL-23 are important cytokines associated with this lineage. The aim of this study was to analyze, through immunohistochemical methods, the immunoexpression of IL-17 and IL-23 in the inflammatory infiltrate of oral lichen planus (OLP) lesion compared to that of inflammatory fibrous hyperplasia (IFH) and between clinical forms reticular and erosive of OLP. The sample included 41 cases of OLP, of which 23 were reticular and 18 erosive and 10 cases of IFH. The results were subjected to nonparametric statistical tests with a 5% significance level. In OLP lesions histomorphological analysis, the most common findings were: hyperparakeratinization, specimens with atrophic epithelium in erosive clinical form (p = 0.011), epithelial projections in most of reticular type of lesions, in addition Civatte bodies were identified in most samples of both clinical forms. For immunohistochemistry analysis, five fields with strong immunoreactivity for IL-17 and IL-23 were photomicrographed at 400x magnification, images were transferred to a computer where with ImageJ software®, lymphocytes that exhibited cytoplasmic immunostaining for these cytokines were counted. A mean was established after for each case. There was no statistically significant difference in the number of imunopositive lymphocytes for IL-17 and IL-23 among the group of OLP and IFH group, however a larger amount of lymphocytes imunopositive for IL-17 was found in the LPO group (p = 0.079) and significantly higher amounts of those lymphocytes were found in the erosive OLP when compared to the group of reticular OLP and IFH (p = 0.019). Furthermore, a marker epithelial immunopositivity for IL-17 was observed in OLP group. Although the results of this study do not permit the forceful assertion about the participation of Th17 lineage in OLP lesions, the findings of immunopositive lymphocytes counting for IL-17 and IL-23, which are potent proinflammatory cytokines, together with the the marked epithelial immunopositivity found for IL-17 in this study, suggest a possible role of this lineage in the pathogenesis of this disorder

Avaliação da angiogênese em lesões de líquen plano oral e pênfigo vulgar

Oral lichen planus and pemphigus vulgaris are chronic diseases mucous membrane immune of unknown aetiology that can be observed affecting to the oral mucous. A relevant as regards neoplasies the role angiogenesis in the inflammatory chronic disease pathogenesis as it provides a substancial interest can be considered as being an activity diseases marker; besides being through specialised research of this angiogenic process to improve of understanding pathogenic mechanism. This research proposes to assess angiogenic active through of antibody immunohistochemistry expression antiCD34 antibody in 26 OLP of reticular cases, 14 OLP erosives cases, 18 of PV cases and 15 specimens of normal oral mucosa. The result was submitted non-parametric tests of 5% significance level. It is not statistically significant correlacion was seen regarding between average vessels. However, only be effectively observed the median of OLP cases was larger than pemphigus vulgaris in fact proved average larger than oral normal mucosa (p=0,280). Regarding the microvascular count of CD34 concerning clinic form oral lichen planus (reticular and erosion) increased emphasis is more cross-border average for the form erosion clinic. Despite of the statistic tests could not be more effective (p=0,720). Even though, the results of the research is not sufficient to enable to consider of angiogenic process in the pathogenesis and lesions progression of oral lichen planus and pemphigus vulgaris, we suggest this process is present in both forms lesion, however, more studies must be made in the near future in order to prepare a well-founded proposal

Um estudo algorítmico para otimização do plano de tratamento da radioterapia conformal

This work performs an algorithmic study of optimization of a conformal radiotherapy plan treatment. Initially we show: an overview about cancer, radiotherapy and the physics of interaction of ionizing radiation with matery. A proposal for optimization of a plan of treatment in radiotherapy is developed in a systematic way. We show the paradigm of multicriteria problem, the concept of Pareto optimum and Pareto dominance. A generic optimization model for radioterapic treatment is proposed. We construct the input of the model, estimate the dose given by the radiation using the dose matrix, and show the objective function for the model. The complexity of optimization models in radiotherapy treatment is typically NP which justifyis the use of heuristic methods. We propose three distinct methods: MOGA, MOSA e MOTS. The project of these three metaheuristic procedures is shown. For each procedures follows: a brief motivation, the algorithm itself and the method for tuning its parameters. The three method are applied to a concrete case and we confront their performances. Finally it is analyzed for each method: the quality of the Pareto sets, some solutions and the respective Pareto curves

Desenvolvimento territorial e a política nacional de água em Moçambique: o caso do distrito de Chibuto

The development has been a phenomenon in constant discussion today, whose fundamental importance should be to promote the welfare of humanity. Thus, the development becomes an element that adds political, economic, social and environmental values . In Mozambique the development model adopted by the State prioritizes the economic dimension, in this case favoring the growth of capitalist structure production. Thus , the basic conditions for human survival still leaves much to be desired and the Mozambican population in general and the district of Chibuto , in particular , continue to face several difficulties to have access to such conditions, and the lack of potable water is a that most of the problems afflicting this population . The water was always a factor related to the socio-economic development of the population, where great civilizations and major economic marks were always influenced by water availability, and today this feature is present in all sectors of production. In Mozambique, much effort has been made by the government, national and international organizations to enhance and guarantee the supply of potable and drinking water, and despite all this effort, most of the population does not have access to this precious resource. In this sense, this work presents an analysis of the effects of the National Water Policy in the study area, analyzes the shortage of potable water in the district of Chibuto, discusses the design and development contained in the official discourse of the state and, opposes the idea of human development. For such issues that help to understand the phenomenon under study, such as territory, public policy and criticism of hegemonic conception of development are addressed. To make the desired approach, we performed a characterization of the District of Chibuto, addressing the issue of poverty, with a brief discussion of this concept, from different approaches, and analyze the impact of the PARPA (Action Plan for the Reduction of Absolute Poverty) in fighting poverty in Mozambique, and became a description of the scenario of poverty and vulnerability in Chibuto district with the construction of Territorial Human Development Index. Research also brings up a discussion about territory and technicization which describes the senary of the water supply system in the District and territorial dynamics of Chibuto, from the analysis and description of existing structures and other technical objects that structure the territory under study. Thus, it was found that the development should be summarized in the satisfaction of human needs, and should be the cornerstone of the new type of development that is intended for the purpose of triggering urgently actions to overcome or combat bleak misery suffered by the majority of inhabitants of the District of Chibuto
