Systemic Indicators

O artigo traça crítica a indicadores urbanos usuais, baseados na intensidade de presença de características ou propriedades, e aponta a necessidade de indicadores de comportamento definidos pelo conhecimento do impacto da trama de propriedades espaciais sobre as dinâmicas da cidade – indicadores verdadeiramente de desempenho, aptos a avaliara cidade como fenômeno dinâmico e relacional, no qual seus componentes e dimensões têm efeitos uns sobre os outros. Indicadores capazes de capturar, por exemplo, os modos como diferentes padrões de morfologia podem impactar a vida microeconômica, a sociabilidade urbana ou o ambiente em níveis de influência sobre tendências de menor ou maior dependência veicular na movimentação intraurbana. Para tanto, lança os fundamentos teóricos e metodológicos para um novo sistema de indicadores arranjados em dois eixos: metaindicadores de desempenho(equidade, eficiência, qualidade espacial e sustentabilidade) e dimensões urbanas(morfologia, dinâmica socioeconômica, limiares urbanos e relações cidade–ambiente). Palavras-chave: desempenho e comportamento urbano; indicadores sistêmicos; planejamento. Abstract: The present work proposes concepts and indicators intended to grasp features and effects of urban form; in fact, systemic indicators defined to tackle cityscapes as relational processes whose constituents are pervaded by mutual effects. Firstly, it brings a critique of indicators found in the literature, asserting that most indicators are feature indicators rather than performance indicators. Secondly, it advances theoretical and methodological grounds for new indicators geared to assess the impacts of urban structure on aspects of social life, equity in the access to jobs and facilities, the efficiency of locational patterns in economic interactions, and the sustainability of urban reproduction. Thirdly, anew set of indicators is proposed and arranged in two major groups: (i) performance indicators (spatial quality, urban equity, efficiency and sustainability), and (ii) meta-indicators for urban dimensions (general indicators of urban morphology, socioeconomy, criticality, and city environment relations). Finally, the paper discusses possibilities of application and further development, and brings mathematical definitions of the systemic indicators. Keywords: urban performance; systemic indicators; criticality.

Abstract Background: To determine the prevalence and associations of asteroid hyalosis (AH) in a Chinese population-based cohort.Methods: The population-based Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6 ± 9.8 years (range: 50-93 years). AH is a condition in which small yellow-white, spherical particles known as asteroid bodies (ABs) are present within the vitreous body.Results: Fundus photographs were gradable in 3419 subjects. AH was detected in 65 (0.9%, 95% CI: 0.7%, 1.2%) eyes of 53 (1.5%, 95% CI: 1.1%, 1.9%) subjects. AH was bilateral in 18.9%. Mean age of all subjects with AH was 69.2± 9.5 years (median, 71.0 years; range, 51–91 years), mean refractive error was 0.63±1.53D (median, 0.75 D; range, -4.12 to 4.00D). In multivariate analysis, prevalence of AH was associated with elder age (P=0.014, OR 1.057), thicker lens (P=0.034, OR 3.843), higher refractive error (P=0.016, OR 1.401).Conclusions: In adult Chinese in Beijing, the prevalence of AH was 0.9% for eyes or 1.5% for subjects. AH was associated with elder age, thicker lens and higher refractive error. It does not support previous observations of an association of AH with diabetes or other systemic indicators.
