The Alliance for Progress and Housing Policy in Rio de Janeiro and Buenos Aires in the 1960s

This article explores the construction of publicly financed low-income housing complexes in Rio de Janeiro, Brazil, and Buenos Aires, Argentina, in the 1960s. These housing developments were possible thanks to the arrival of foreign economic and technical assistance from the Alliance for Progress. Urban scholars, politicians, diplomats and urbanists of the Americas sought to promote middle-class habits, mass consumption and moderate political behaviour, especially among the poor, by expanding access to homeownership and ‘decent’ living conditions for a burgeoning urban population. As a result, the history of low-income housing should be understood within broader transnational discourses and practices about the ‘modernization’ and ‘development’ of the urban poor.

Comparison of excess radiological risk of building materials and industrial by-products according to I-index (EU-BSS) and revised room model (IAEA SSG-32)

To get a better insight into the radiological features of industrial by-products that can be reused in building materials a review of the reported scientific data can be very useful. The current study is based on the continuously growing database of the By-BM (H2020-MSCA-IF-2015) project (By-products for Building Materials). Currently, the By-BM database contains individual data of about 431 by-products and 1095 building and raw materials. It was found that in case of the building materials the natural radionuclide content varied widely (Ra-226: <DL-27851 Bq/kg; Th-232: <DL-906 Bq/kg, K-40: <DL-17922 Bq/kg), more so than for the by-products (Ra-226: 7-3152 Bq/kg; Th-232: <DL-1350 Bq/kg, K-40: <DL-3001 Bq/kg). The average Ra-226, Th-232 and K-40 contents of the reported by-products were respectively 2.52, 2.35 and 0.39 times higher than the building materials. The gamma exposure of bulk building products was calculated according to IAEA Specific Safety Guide No. SSG-32 and the European Commission Radiation Protection 112 based I-index (EU BSS). It was found that in most cases the I-index without density consideration provides a significant overestimation in excess effective dose.

Territoriality and the regulation of public space in Favela Morro da Formiga, Rio de Janeiro

Public space in many communities around the world has been identified as over-regulated and devoid of social vibrancy. This research contributed new knowledge regarding the way local residents territorialise and take ownership of streets and open areas in a favela, or informal settlement, in Rio De Janeiro, Brazil. Findings showed that public spaces were only partly activated by spatial pattern or structure. User agency also played a significant role, despite recent regulatory and policing interventions in the favela. This may have important implications for new communities where design could allow for more flexible usage and thereby enhance social vibrancy.

The VINEYARD Approach: Versatile, Integrated, Accelerator-Based, Heterogeneous Data Centres.

Emerging web applications like cloud computing, Big Data and social networks have created the need for powerful centres hosting hundreds of thousands of servers. Currently, the data centres are based on general purpose processors that provide high flexibility buts lack the energy efficiency of customized accelerators. VINEYARD aims to develop an integrated platform for energy-efficient data centres based on new servers with novel, coarse-grain and fine-grain, programmable hardware accelerators. It will, also, build a high-level programming framework for allowing end-users to seamlessly utilize these accelerators in heterogeneous computing systems by employing typical data-centre programming frameworks (e.g. MapReduce, Storm, Spark, etc.). This programming framework will, further, allow the hardware accelerators to be swapped in and out of the heterogeneous infrastructure so as to offer high flexibility and energy efficiency. VINEYARD will foster the expansion of the soft-IP core industry, currently limited in the embedded systems, to the data-centre market. VINEYARD plans to demonstrate the advantages of its approach in three real use-cases (a) a bio-informatics application for high-accuracy brain modeling, (b) two critical financial applications, and (c) a big-data analysis application.

A novel method to count the red blood cells in thin blood films

This paper describes a novel idea to identify the total number of red blood cells (RBCs) as well as their location in a Giemsa stained thin blood film image. This work is being undertaken as a part of developing an automated malaria parasite detection system by scanning a photograph of thin blood film in order to evaluate the parasitemia of the blood. Not only will this method eliminates the segmentation procedures that are normally used to segment the cells in the microscopic image, but also avoids any image pre-processing to deal with non uniform illumination prior to cell detection. The method utilizes basic knowledge on cell structure and brightness of the components due to Giemsa staining of the sample and detects and locates the RBCs in the image.

Identificação de fácies em perfis de poço com algoritmo inteligente

A identificação de fácies em um poço não testemunhado é um dos problemas clássicos da avaliação de formação. Neste trabalho este problema é tratado em dois passos, no primeiro produz-se a codificação da informação geológica ou da descrição das fácies atravessadas em um poço testemunhado em termos das suas propriedades físicas registradas nos perfis geofísicos e traduzidas pelos parâmetros L e K, que são obtidos a partir dos perfis de porosidade (densidade, sônico e porosidade neutrônica) e pela argilosidade (Vsh) calculada pelo perfil de raio gama natural. Estes três parâmetros são convenientemente representados na forma do Gráfico Vsh-L-K. No segundo passo é realizada a interpretação computacional do Gráfico Vsh-L-K por um algoritmo inteligente construído com base na rede neural competitiva angular generalizada, que é especializada na classificação de padrões angulares ou agrupamento de pontos no espaço n-dimensional que possuem uma envoltória aproximadamente elipsoidal. Os parâmetros operacionais do algoritmo inteligente, como a arquitetura da rede neural e pesos sinápticos são obtidos em um Gráfico Vsh-L-K, construído e interpretado com as informações de um poço testemunhado. Assim, a aplicação deste algoritmo inteligente é capaz de identificar e classificar as camadas presentes em um poço não testemunhado, em termos das fácies identificadas no poço testemunhado ou em termos do mineral principal, quando ausentes no poço testemunhado. Esta metodologia é apresentada com dados sintéticos e com perfis de poços testemunhados do Campo de Namorado, na Bacia de Campos, localizada na plataforma continental do Rio de Janeiro, Brasil.

Social dimensions of macroeconomic policy: report of the Executive Committee on Economic and Social Affairs of the United Nations

Introduction The social agenda is long-term in nature, in the sense that poverty alleviation along with a better distribution of income, wealth and opportunities are long-term goals. A sound macroeconomic policy, on the other hand, has to do largely with the consistent management of short-term policy instruments pursuing a sustainable and predictable pace for aggregate economic variables and major prices (wages, inflation, interest rates and exchange rates). In spite of the different arena and rationale in which they play, there are strong links between the two. First and most obvious, macroeconomic adjustment and structural reform are more likely to be sustainable when they are equitable. Second, social intervention —i.e., policies, programmes and reforms aimed at improving social performance in the long run—, needs stable funding which is not always available in view of macroeconomic constraints. Third, macroeconomic instability —especially episodes of recession or hyperinflation— increases poverty and inequality, while restoring macroeconomic equilibrium does not restore previous social balances. Finally, there is no unique macroeconomic policy mix to tackle a given situation, and the policy options may not be neutral from a social standpoint. Monetary, fiscal and exchange rate policies, together with structural reform, have major consequences for the social wellbeing of societies, not only in terms of protection against shocks and crises but also in terms of equity. Many, if not all, of the necessary social policies are of a domestic nature. This report thus concentrates on domestic strategies aimed at maximizing the linkages between consistent macroeconomic policies and social progress. Pursuing them, however, depends to a considerable extent on the international enabling environment in which the global financial system, the unsettled debt crisis and increasing ODA flows play a significant role. Countries operate in a world economy where market players everywhere immediately scrutinize domestic monetary, financial or fiscal policy decisions and the performance of exchange rate regimes of individual countries. Under these conditions, the room for manoeuvre of policymakers has become considerably constrained. Consequently, it is becoming increasingly complex to incorporate the social dimensions into such policy decisions, to the extent that external analysts consider that authorities are sacrificing sound macroeconomic policies. The main message of the report is that the expediency of short-term economic efficiency as embedded in much of the advice on macroeconomic stability needs to be tempered by long-term development objectives. The report starts with a short historical background which describes the ascendancy of macroeconomic policies over social development policies (chapter I). It continues with an evaluation of the relation between macroeconomic consistency and social effort (chapter II), and the importance of sustainable and stable growth for social progress (chapter III). The report then turns to the need for an equity-enhancing growth strategy (chapter IV) and an analysis of the priorities of social policies in an integrated approach to growth (chapter V). The final chapter adds some final institutional remarks.
