Wiki: Plataforma Colaborativa para uma Comunicade de Prática Virtual Lusófona

Com este trabalho procura-se encontrar uma solução através de um modelo para a gestão do conhecimento numa organização internacional com base em tecnologia web 2.0 que sirva de plataforma colaborativa na criação e disseminação de conhecimento para uma comunidade de prática virtual, mas também que sirva de repositório da memória organizacional. Pretende-se, igualmente, demonstrar um novo modelo de organização social e económico, no qual se assume uma orientação para as pessoas enquanto elemento de um sistema social mais amplo, globalizado e disperso, ligado pelas tecnologias de participação e colaboração através do acesso à internet, que encontra na utilização destas ferramentas um interface para participação que vai desde a cidadania, à produção intelectual, criação de conhecimento e ao negócio, neste caso relacionado com uma prática, a gestão de recursos humanos nos países lusófonos. No decurso do projeto, estabeleceram-se contactos e reuniões de trabalho na sede da comunidade interessada, a CRHLP – Confederação de Profissionais de Recursos Humanos de Língua Portuguesa, cujos resultados constam do presente relatório para explicação das várias fases do projeto. O projeto culmina com uma proposta de um site colaborativo com base num Wiki (site Wiki), tecnologia de colaboração online, a Wiki-CRHLP – Plataforma de colaboração para a partilha do conhecimento de uma rede de prática virtual (rede profissional internacional).

Tool for spatial and dynamic representation of artistic performances

This proposal aims to explore the use of available technologies for video representation of sets and performers in order to serve as support for composition processes and artistic performer rehearsals, while focusing in representing the performer’s body and its movements, and its relation with objects belonging to the three-dimensional space of their performances. This project’s main goal is to design and develop a system that can spatially represent the performer and its movements, by means of capturing processes and reconstruction using a camera device, as well as enhance the three-dimensional space where the performance occurs by allowing interaction with virtual objects and by adding a video component, either for documentary purposes, or for live performances effects (for example, using video mapping video techniques in captured video or projection during a performance).

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.

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.
