title: Politics on the Web: Using Twitter to Estimate the Ideological Positions of Brazilian Representatives

description: The use of social media has become increasingly widespread among citizens and politicians in Brazil. This means of communication served as a key arena for debate and propaganda during the 2014 legislative and presidential elections, when a very polarized political scenario emerged. New approaches have been developed that use information from the social network structure constructed by political actors on social media platforms, such as Twitter, in order to calculate ideal points. Can data from the decision to 'follow' a profile on Twitter be used to estimate politicians' ideological positions? Can approaches like this show the variance of political positions even within a very fragmented legislative body, such as the Brazilian Chamber of Deputies? This article presents and analyzes the successful application of a Bayesian spatial model developed by Barberá (2015), using data from Brazil. This method allowed to capture differences between parties and political actors similar to those found by means of roll call votes. It also makes possible to calculate ideal points for actors who participate in the public debate, but are not professional politicians.

title: Dynamics of the real estate market in historic centers in times of globalization: the cases of Recife, Belém and São Luís (Brazil)

description: Abstract The slow growth of Brazilian economy since the 1990s and its insertion into the global economy have brought consequences for historic centers. Political-administrative decentralization and competition among cities for private investment have prompted local governments to invest in these centers to attract activities, which has affected their real estate market dynamics. This article compares how these market dynamics have occurred in the Historic Centers of Recife, Belém and São Luís (Northeastern Brazil) and the effects on their spatial organization, showing their regularities and specificities. As a result of these dynamics, pre-existing spaces (degraded areas) are sometimes reproduced or, otherwise, recreated by way of requalification. This reveals the different ways in which these centers are inserted in the global economy.

title: Effect of the Fiber Orientation Relatively to the Plasma Flow Direction in the Ablation Process of a Carbon-Phenolic Composite

description: ABSTRACT: Composite materials are vastly employed in rocket nozzle extensions and as thermal protection shields in aerospace industry. In both cases, ablative and thermal properties play an important role for material choice and equipment sizing. These properties are strongly dependent on the way the pieces are manufactured. For the case of nozzle extensions, wrapping is the most common technique employed, which can be done by diverse ways. In this work, samples of the carbon reinforced carbon fiber (CRCF) were extracted from pre-forms obtained by biased and parallel tape wrapping processes with a resol-type phenolic resin used as polymer matrix, in order to study the influence of the fiber angle in the ablative behavior and thermal conductivity. Experimental results for both manufacturing techniques were obtained through ablation tests carried out in a plasma torch, were compared and had the different behaviors discussed. A computational simulation based in a two-front ablation model was also performed, in order to explain the influence of thermal conductivity on the different behaviors presented for biased fiber samples. Results show that the angle of the fibers relative to the heat flux direction is an important parameter to determine the ablative properties and the thermal performance of composite wrapped structures.

title: Human resources: critical factor for primary health networks

description: This article aims to describe the profile of the orthodontists, nurses and physicians involved in the Family Health Strategy at the municipality of Montes Claros - MG and insert it in context of the Primary Health Networks (PHNs). A high level of professional training is observed, although a weak employment link also applies. It is known that human resources are an overriding element to reach a good performance at the PHNs, once they should be prepared to act as protagonists of governance systems, managing the resources towards community. It is still necessary that health system' managers provide health personnel with all professional guarantees so to reach excellence in primary health.

title: Operationalized definition of older adults with high cognitive performance

description: ABSTRACT Recently, there has been an increasing number of studies on exceptional cognitive aging. Herein, we aim to objectively provide the operationalized characterization of older adults with unusually high memory ability. Some authors have defined them as “SuperAgers”, individuals aged 80 years or older with memory ability similar or superior to middle-aged subjects. On the other hand, the terminology “high-performing older adults” (HPOA) seems to appropriately conceptualize these individuals without exaggeration. A threshold for age is not a reliable criterion, but may be defined as 75 and 80 years of age for developing and developed countries, respectively. We propose that HPOA may exhibit episodic memory test scores equal to or greater than those of individuals aged 50-60 years, according to the validated tables for the respective country. This group must also have global cognition scores within expected average values for age and education. Executive functioning may play a central role in the exceptional memory performance of this group. Further studies are essential to confirm existing findings and may provide important evidence for cognitive aging theory and the neurobiology of dementia.

title: Endemic Pemphigus Foliaceus (Fogo Selvagem) and its association with environmental and occupational factors in Ouro Preto, Minas Gerais, Brazil

description: Abstract Pemphigus comprises a group of autoimmune bullous diseases, which have a tendency of progression, with unlimited and chronic development and with a potentially to fatal disease prognosis. The most common type is the Endemic Pemphigus Foliaceus (EPF), characterized by the presence of skin lesions with blistering located on the face, scalp and interscapular region. Environmental, genetic and immunological factors may trigger the disease. Among the environmental factors, exposure to mercury, mineral dust and Simulium nigrimanum mosquitoes bite should be considered. Sought to, in this article, it is reported the occurrence of PFE among the population of Antonio Pereira, rural district of Ouro Preto, Minas Gerais, and identify their possible association with occupational and environmental local factors. A prevalence of 4.57 cases of EPF/1.000 inhabitants, considered high was found. There was association between the disease and contact with dam tailings mining (p=0.048); and exposure to mercury (p=0.008). The results indicate the need for effective surveillance of the affected communities, as well as adequate health care of patients affected by the disease.

title: Organizational Culture under the Perspective of the Brazilian Regional Culture

description: ABSTRACT This essay has the objective of analyzing the Brazilian cultural context and its influence on the organizations universe from a cultural regional perspective that goes beyond the functionalist paradigm and advances through contemporary concepts, like cultural flows and the local cultural codes. In an international perspective, in studies that consider the perspective of cultural adaptation, it is possible finding a significant volume of research that emphasizes the distinctions between regions or nations. On the other hand, when it these studies deal with this perspective inside each culturally diversified country it seems that there isn’t the same expression in the rural areas. In Brazil there isn’t the same intensity of effort of research. Besides, in our country the cultural diversity is recognized, and the analyses that consider the influences of the culture variable can potentially contribute for the efficiency of the organization’s internal and external relations. It is defended that organizations need to contemplate in their actions what it is called local cultural legitimacy, especially when these organizations work in distinct contexts, respecting the local values and cultural practices. Brazil has different cultural regions where it is possible finding different consumers and employees and distinct cultural codes that indicate the need of different forms of management.

title: Tomato seed image analysis during the maturation

description: Abstract: The seed physiological potential has been directly related to normal formation process under morphological, structural and functional point of view. The objective of this study was to evaluate the internal morphology of ‘BRS Nagai’ tomato hybrid seeds at different stages of development and maturation, through the X-ray image analysis and relate the results with the seed germination and vigor. Seeds were extracted from fruits harvested at 30, 40, 50, 60 and 70 days after pollination (DAP). Subsequently, seeds were x-rayed with their images analyzed visually for the embryo morphology classification; also, the measurement of clearance between the embryo and endosperm was performed with the help of the ImageJ software. These results were compared with the seed physiological quality by germination. The correlations involving the analysis of X-ray showed that the seeds have embryos classified as normal tend to have higher vigor and produce normal seedlings. On the other hand, seeds with higher internal free area tend to have low vigor and higher percentage of abnormal seedlings. The image analysis using X-rays is efficient for the study of physiological maturity of tomato seeds. The analysis of X-rays may predict seed performance by means of the embryo morphology, permitting the selection of high quality seeds. Tomato seeds of fruits with up to 40 days after pollination have low morphophysiological quality when compared to seeds extracted from fully mature fruits, from 60 days after pollination.

title: SÃO SEBASTIÃO DO RIO DE JANEIRO AND JAMESTOWN (VIRGINIA): PRELIMINARY CONSIDERATIONS ABOUT REBELLIONS, CITIES, AND SPACE IN THE AMERICAS (1660-1677)

description: Abstract In Portuguese America, in the late 1660s, a protest erupted in which the local elite overthrow the royal governor and took over the city of Rio de Janeiro for five months. In 1675, in Colony of Virginia, frontier men added to other segments attacked the governor and his allies, sparking a civil war known as Bacon’s Rebellion, in honor of its main leader. This article examines a spatial phenomenon observed from the contrast between these two rebellions. While in Rio de Janeiro, rebel actions converge on the space of the city of São Sebastião in Rio de Janeiro, reinforcing the central role of the capital where negotiations and protests were concentrated, in Virginia, on the contrary, the spatial dispersion is striking, with the emptying of the capital Jamestown that was totally burnt down during the conflicts that spread across the territory.

title: RIO DE JANEIRO AND THE SILVER MINING ECONOMY OF POTOSI: TRANS-IMPERIAL, GLOBAL, AND CONTRACTUAL APPROACHES TO SOUTH ATLANTIC MARKETS (18TH CENTURY)

description: Abstract This paper’s main goal is to advance some considerations on the interrelations between port cities and capital. More specifically, it sheds light on how these interdependencies took place in the eighteenth-century Portuguese and Spanish Atlantic world. This paper thus seeks to draw an urban political economy in transimperial, global, and contractual perspectives. For so doing, particular attention will be put to Rio de Janeiro’s projection far beyond the South Atlantic, and in particular, its interconnections with the Rio de la Plata basin and Potosi markets. Attention will also be paid to the impact of and repercussions that far-flung economic phenomena had for the urban domestic markets.
