This paper presents an empirical investigation of Jane Jacobs' observations concerning factors generating success within urban neighborhoods. The basic elements of Jacobs' hypotheses of city neighborhood performance are outlined and regression results uti. lizing Denver as the study area, are presented and compared with findings obtained for Chicago. Additional measures of neighborhood success and failure are introduced in a subsequent canonical correlation analysis to test the overall validity of Jacbos' thesis, In general the empirical analyses provide little supportive evidence for the hypothesized relationships.
This paper includes an analysis of the evolution of urban spatial cognition over time among a sample of Chinese students attending Zhongshan University in Guangzhou, China. Changes in the features of sketch maps, based on classifications developed by Lynch, Appleyard, as well as Golledge, are examined. The slow evolution of urban cognition and the tendency to construct maps of the same style and structure over time are noted. Explanations for the absence of changes hypothesized by various investigators are offered.
This study focuses on the competitive processes and locational patterns of a convenience retail activity within two urban areas exhibiting distinct differences in operational characteristics. Impacts of various economic, demographic, and political environmental factors on the distribution of gasoline service stations in urbanized Hong Kong and metropolitan Denver are examined. Measurement of distributional patterns (utilizing nearest-neighbor and spatial association statistics) and socioeconomic/demographic influences (employing regression analysis) reveal remarkable similarities between the two areas. Investigation of several site-related characteristics (zoning and intersection orientation) suggests that they may be significant agglomerative influences accounting both for the consistent location patterns as well as the weak explanatory power of demand variables.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
