Studying urban space and literary representations using GIS: Lisbon, Portugal, 1852-2009

This article proposes a methodology to address the urban evolutionary process, demonstrating how it is reflected in literature. It focuses on “literary space,” presented as a territory defined by the period setting or as evoked by the characters, which can be georeferenced and drawn on a map. It identifies the different locations of literary space in relation to urban development and the economic, political, and social context of the city. We suggest a new approach for mapping a relatively comprehensive body of literature by combining literary criticism, urban history, and geographic information systems (GIS). The home-range concept, used in animal ecology, has been adapted to reveal the size and location of literary space. This interdisciplinary methodology is applied in a case study to nineteenth- and twentieth-century novels involving the city of Lisbon. The developing concepts of cumulative literary space and common literary space introduce size calculations in addition to location and structure, previously developed by other researchers. Sequential and overlapping analyses of literary space throughout time have the advantage of presenting comparable and repeatable results for other researchers using a different body of literary works or studying another city. Results show how city changes shaped perceptions of the urban space as it was lived and experienced. A small core area, correspondent to a part of the city center, persists as literary space in all the novels analyzed. Furthermore, the literary space does not match the urban evolution. There is a time lag for embedding new urbanized areas in the imagined literary scenario.

Low frequency of side effects following an incidental 25 times concentrated dose of yellow fever vaccine

In August/1999, a group of 14 adults from the staff of a private hospital in Contagem -- Minas Gerais State, Brazil, received unintentionally a 25 times concentrated dose of the 17-DD yellow fever vaccine (Bio-Manguinhos), due to a mistake at the reconstitution step. All patients were clinically and laboratorially evaluated at days 5, 13 and 35 post vaccination. Frequency of side effects and clinical observations of this group of individuals were not different from the observed in recipients immunized with normal doses of the vaccine. At the second and third evaluation none of the subjects reported symptoms. None of the patients presented abnormalities at the physical examination at none of the time points and in all cases the blood examination was normal, except for a reduced number of platelets that was detected in one subject at the first and second evaluation and reverted to normal at third evaluation. At the first evaluation point, 8 subjects were serum negative and 6 serum positive for yellow fever at the plaque reduction neutralization test. In 5 subjects the observed titre was 10 times higher as the baseline of 2.36 Log10 mUI/ml. The samples collected at second and third evaluation (13th and 35th days) demonstrated that all subjects responded to the vaccination with the exception of one that did not present a positive result in any of the samples collected. This evaluation confirms the safety of the 17-DD yellow fever vaccine.

Pedestrian Priority Zones in the Context of Urban Mobility and Valorization of Public Space

The second half of the XX century was marked by a great increase in the number of people living in cities. Urban agglomerations became poles of attraction for migration flows and these phenomena, coupled with growing car-ownership rates, resulted in the fact that modern transport systems are characterized by large number of users and traffic modes. The necessity to organize these complex systems and to provide space for different traffic modes changed the way cities look. Urban areas had to cope with traffic flows, and as a result nowadays typical street pattern consists of a road for motorized vehicles, a cycle lane (in some cases), pavement for pedestrians, parking and a range of crucial signage to facilitate navigation and make mobility more secure. However, this type of street organization may not be desirable in certain areas, more specifically, in the city centers. Downtown areas have always been places where economic, leisure, social and other types of facilities are concentrated, not surprisingly, they often attract large number of people and this frequently results in traffic jams, air and noise pollution, thus creating unpleasant environment. Besides, excessive traffic signage in central locations can harm the image and perception of a place, this relates in particular to historical centers with architectural heritage.

On an organizational level: How can the emergency department at Rouge Valley Centenary hospital improve their wait times?

The prolonged wait times may arguably put into question the Canadian Health Act of 1984. Statistics show throughput wait times are 5.5 hours and output wait times for admitted patients are 32.4 hours. After probing and analyzing best practices through a qualitative/quantitative Value Stream Mapping and a qualitative SWOT Analysis; Team Triage and an Overcapacity Protocol is suggested to improve non-admitted patients wait times by 1.89 hours and admitted patients wait times by 16 hours by eliminating wasteful steps in the patient process and upon overcapacity, effectively sharing already stabilized and admitted patients with all wards in the hospital.

Structural transformation in the product space: Patterns and implications

Product fundamentals are essential in explaining heterogeneity in the product space. The scope for adapting and transferring capabilities into the production of different goods determines the speed and intensity of the structural transformation process and entails dissimilar development opportunities for nations. Future specialization patterns become then partly determined by the current network of products’ relatedness. Building on previous literature, this paper explicitly compares methodological concepts of product connectivity to conclude in favor of the density measure we propose combined with the Revealed Relatedness Index (RRI) approach presented by Freitas and Salvado (2011). Overall, RRI specifications displayed more consistent behavior when different time horizons are equated.

A Realidade do Tempo – uma análise de Durée et Simultanéité de Henri Bergson

Este trabalho aborda a questão da realidade do tempo na obra Durée et Simultanéité de Henri Bergson. Primeiramente, explicita-se o sentido dos termos necessários para uma compreensão da natureza do tempo: “duração”, “memória”, “virtual”, “real”, “sucessão” e “simultaneidade”. O objectivo desta análise é compreender de que forma se relacionam estes conceitos e em que sentido a consciência do tempo pode tomar-se como raiz da constituição temporal. A abordagem destes conceitos conduz também à problemática da multiplicidade de tempos, que é inicialmente discutida em relação aos termos previamente referidos. Seguidamente, estabelece-se a relação entre o temporal e o intemporal, considerando de que forma surge a ideia de eternidade numa realidade que é essencialmente temporal. Neste ponto, considera-se a visão de duração como privação de eternidade e a questão de se é possível e como é possível uma consciência universal. O último tópico abordado no trabalho diz respeito à unicidade do tempo. O estudo da realidade no tempo partiu da distinção entre o tempo real e o tempo espacializado. Posteriormente, observámos, através da consideração das relações eu-outro, em que sentido se pode falar de um único tempo. Com a pretensão de chegar à hipótese de um único tempo vivido clarificámos o problema da multiplicidade de tempos. Por último, considerámos a possibilidade de um mundo sem consciência.

Pulmonary tuberculosis in São Luis, State of Maranhão, Brazil: space and space-time risk clusters for death (2008-2012)

INTRODUCTION: The objective was to identify space and space-time risk clusters for the occurrence of deaths in a priority city for the control of tuberculosis (TB) in the Brazilian Northeast. METHODS: Ecological research was undertaken in the City of São Luis/Maranhão. Cases were considered that resulted in deaths in the population living in the urban region of the city with pulmonary TB as the basic cause, between 2008 and 2012. To detect space and space-time clusters of deaths due to pulmonary TB in the census sectors, the spatial analysis scan technique was used. RESULTS: In total, 221 deaths by TB occurred, 193 of which were due to pulmonary TB. Approximately 95% of the cases (n=183) were geocoded. Two significant spatial clusters were identified, the first of which showed a mortality rate of 5.8 deaths per 100,000 inhabitants per year and a high relative risk of 3.87. The second spatial cluster showed a mortality rate of 0.4 deaths per 100,000 inhabitants per year and a low relative risk of 0.10. A significant cluster was observed in the space-time analysis between 11/01/2008 and 04/30/2011, with a mortality rate of 8.10 deaths per 100,000 inhabitants per year and a high relative risk (3.0). CONCLUSIONS: The knowledge of priority sites for the occurrence of deaths can support public management to reduce inequities in the access to health services and permit an optimization of the resources and teams in the control of pulmonary TB, providing support for specific strategies focused on the most vulnerable populations.

Fractional state space analysis of economic systems

This paper examines modern economic growth according to the multidimensional scaling (MDS) method and state space portrait (SSP) analysis. Electing GDP per capita as the main indicator for economic growth and prosperity, the long-run perspective from 1870 to 2010 identifies the main similarities among 34 world partners’ modern economic growth and exemplifies the historical waving mechanics of the largest world economy, the USA. MDS reveals two main clusters among the European countries and their old offshore territories, and SSP identifies the Great Depression as a mild challenge to the American global performance, when compared to the Second World War and the 2008 crisis.

Two decades of tuberculosis in a city in Northeastern Brazil: advances and challenges in time and space

Abstract: INTRODUCTION This study presents two decades of epidemiological data on tuberculosis (TB), in order to understanding the disease profile and its spatiotemporal dynamics. METHODS This descriptive study was performed in the City of Olinda/Pernambuco, Brazil, from 1991-2010, and it analyzed new patients with TB living in the city. We used the χ²-test with a p-value <0.05 to identify differences in trends. Incidence and cluster distribution were identified using spatial scan statistics. RESULTS In total, 6202 new cases were recorded during the two decades. The highest incidence occurred in 1995 (110 cases/100,000 inhabitants), and the lowest occurred in 2009 (65 cases/100,000 inhabitants) (β=-1.44; R²=0.43; p=0.0018). The highest mortality occurred in 1998 (16 deaths/100,000 inhabitants), and the lowest occurred in 2008 (5 deaths/100,000 inhabitants) (β=-0.19; R²=0.17; p=0.07). There was a male predominance (65%), and ages ranged from 20-49 years (65%). There was a substantial increase in the number of patients that were cured after treatment (60% to 67%; p<0.001) as well as those tested for HIV (1.9% to 58.5%; p<0.001). During the first decade, clusters with p-values <0.05 included 29% of the total notified cases, and in the second decade, that percentage was 12%. CONCLUSIONS We observed a decreasing trend in incidence, which was significant, and mortality rates, which was not significant. The increased number of laboratory tests performed reflects advances in surveillance, and a reduction in the proportion of cases in primary clusters suggests, among other things, that the disease is spreading across the region.

Entre a plasticidade do corpo e da imagem : contributos para uma viagem interactiva pelos territórios incertos da arte contemporânea

Este trabalho de investigação começou por ser estruturado em torno de quatro grandes capítulos (quatro grandes linhas de orientação temática), todos eles amplamente desenvolvidos no sentido de podermos cartografar alguns dos principais territórios e sintomas da arte contemporânea, sendo certo também, que cada um deles assenta precisamente nos princípios de uma estrutura maleável que, para todos os efeitos, se encontra em processo de construção (work in progress), neste caso, graças à plasticidade do corpo, do espaço, da imagem e do uso criativo das tecnologias digitais, no âmbito das quais, aliás, tudo se parece produzir, transformar e disseminar hoje em dia à nossa volta (quase como se de uma autêntica viagem interactiva se tratasse). Por isso, a partir daqui, todo o esforço que se segue procurará ensaiar uma hipótese de trabalho (desenvolver uma investigação) que, porventura, nos permita desbravar alguns caminhos em direcção aos intermináveis túneis do futuro, sempre na expectativa de podermos dar forma, função e sentido a um desejo irreprimível de liberdade criativa, pois, a arte contemporânea tem essa extraordinária capacidade de nos transportar para muitos outros lugares do mundo, tão reais e imaginários como a nossa própria vida. Assim sendo, há que sumariar algumas das principais etapas a desenvolver ao longo desta investigação. Ora, num primeiro momento, começaremos por reflectir sobre o conceito alargado de «crise» (a crise da modernidade), para logo de seguida podermos abordar a questão da crise das antigas categorias estéticas, questionando assim, para todos os efeitos, quer o conceito de «belo» (Platão) e de «gosto» (Kant), quer ainda o conceito de «forma» (Foccilon), não só no sentido de tentarmos compreender algumas das principais razões que terão estado na origem do chamado «fim da arte» (Hegel), mas também algumas daquelas que terão conduzido à estetização generalizada da experiência contemporânea e à sua respectiva disseminação pelas mais variadas plataformas digitais. Num segundo momento, procuraremos reflectir sobre alguns dos principais problemas da inquietante história das imagens, nomeadamente para tentarmos perceber como é que todas estas transformações técnicas (ligadas ao aparecimento da fotografia, do cinema, do vídeo, do computador e da internet) terão contribuído para o processo de instauração e respectivo alargamento daquilo que todos nós ficaríamos a conhecer como a nova «era da imagem», ou a imagem na «era da sua própria reprodutibilidade técnica» (Benjamin), pois, só assim é que conseguiremos interrogar este imparável processo de movimentação, fragmentação, disseminação, simulação e interacção das mais variadas «formas de vida» (Nietzsche, Agamben). Entretanto, chegados ao terceiro grande momento, interessa-nos percepcionar a arte contemporânea como uma espécie de plataforma interactiva que, por sua vez, nos levará a interpelar alguns dos principais dispositivos metafóricos e experimentais da viagem, neste caso, da viagem enquanto linha facilitadora de acesso à arte, à cultura e à vida contemporânea em geral, ou seja, todo um processo de reflexão que nos incitará a cartografar alguns dos mais atractivos sintomas provenientes da estética do flâneur (na perspectiva de Rimbaud, Baudelaire, Long e Benjamin) e, consequentemente, a convocar algumas das principais sensações decorrentes da experiência altamente sedutora daqueles que vivem mergulhados na órbita interactiva do ciberespaço (na condição de ciberflâneurs), quase como se o mundo inteiro, agora, fosse tão somente um espaço poético «inteiramente navegável» (Manovich). Por fim, no quarto e último momento, procuraremos fazer uma profunda reflexão sobre a inquietante história do corpo, principalmente com o objectivo de reforçar a ideia de que apesar das suas inúmeras fragilidades biológicas (um ser que adoece e morre), o corpo continua a ser uma das «categorias mais persistentes de toda a cultura ocidental» (Ieda Tucherman), não só porque ele resistiu a todas as transformações que lhe foram impostas historicamente, mas também porque ele se soube reinventar e readaptar pacientemente face a todas essas transformações históricas. Sinal evidente de que a sua plasticidade lhe iria conferir, principalmente a partir do século XX («o século do corpo») um estatuto teórico e performativo verdadeiramente especial. Tão especial, aliás, que basta termos uma noção, mesmo que breve, da sua inquietante história para percebermos imediatamente a extraordinária importância dalgumas das suas mais variadas transformações, atracções, ligações e exibições ao longo das últimas décadas, nomeadamente sob o efeito criativo das tecnologias digitais (no âmbito das quais se processam algumas das mais interessantes operações de dinamização cultural e artística do nosso tempo). Em suma, esperamos sinceramente que este trabalho de investigação possa vir a contribuir para o processo de alargamento das fronteiras cada vez mais incertas, dinâmicas e interactivas do conhecimento daquilo que parece constituir, hoje em dia, o jogo fundamental da nossa contemporaneidade.
