Abstract Beginning with a discussion of Fritz Lang's ‘Metropolis’, this paper considers the rise of the city from a theological perspective. The ideal of the modern city was, it is argued, a secularised version of the City of God: the city was to be a place where all human desires might be met, a city without a church because the moral perfection of each human being has been fulfilled. The advent of the postmodern city of consumerist desire undermines this secular dream, and opens a space for theologians to frame alternative visions of cities of erotic participatory desire. 相似文献

Imputation methods that assign a selection of respondents’ values for missing i tern nonresponses give rise to an addd,tional source of sampling variation, which we term imputation varLance , We examine the effect of imputation variance on the precision of the mean, and propose four procedures for sampling the rEespondents that reduce this additional variance. Two of the procedures employ improved sample designs through selection of respc,ndents by sampling without replacement and by stratified sampl;lng. The other two increase the sample base by the use of multiple imputations. 相似文献

We explore the application of dynamic graphics to the exploratory analysis of spatial data. We introduce a number of new tools and illustrate their use with prototype software, developed at Trinity College, Dublin. These tools are used to examine local variability—anomalies—through plots of the data that display its marginal and multivariate distributions, through interactive smoothers, and through plots motivated by the spatial auto-covariance ideas implicit in the variogram. We regard these as alternative and linked views of the data. We conclude that the most important single view of the data is the Map View: All other views must be cross-referred to this, and the software must encourage this. The view can be enriched by overlaying on other pertinent spatial information. We draw attention to the possibilities of one-many linking, and to the use of line-objects to link pairs of data points. We draw attention to the parallels with work on Geographical Information Systems. 相似文献

Residential building codes intended to promote health and safety may produce unintended countervailing risks by adding to the cost of construction. Higher construction costs increase the price of new homes and may increase health and safety risks through income and stock effects. The income effect arises because households that purchase a new home have less income remaining for spending on other goods that contribute to health and safety. The stock effect arises because suppression of new-home construction leads to slower replacement of less safe housing units. These countervailing risks are not presently considered in code debates. We demonstrate the feasibility of estimating the approximate magnitude of countervailing risks by combining the income effect with three relatively well understood and significant home-health risks. We estimate that a code change that increases the nationwide cost of constructing and maintaining homes by $150 (0.1% of the average cost to build a single-family home) would induce offsetting risks yielding between 2 and 60 premature fatalities or, including morbidity effects, between 20 and 800 lost quality-adjusted life years (both discounted at 3%) each year the code provision remains in effect. To provide a net health benefit, the code change would need to reduce risk by at least this amount. Future research should refine these estimates, incorporate quantitative uncertainty analysis, and apply a full risk-tradeoff approach to real-world case studies of proposed code changes. 相似文献

While school-based adolescent victimization has received a great deal of public attention, there exist relatively few theoretically driven studies aimed at explaining this phenomenon. We address this paucity by providing a test of a criminal-opportunity model of school-based victimization using data on over 3,000 students from 40 different Kentucky middle and high schools. The effects of opportunity-related concepts are estimated for both violent and property victimization, and comparisons are made for each victimization type across middle- and high-school student subsamples. Findings suggest that criminal opportunity theory is relevant to the understanding of school-based victimization. In particular, indicators of exposure to crime and target antagonism appear to be robust predictors. Further, there appears to be substantial generalizability in the effects of opportunity-related variables across violent versus property victimization as well as across middle-school versus high-school contexts. 相似文献

This paper considers the design of a Scheduling Sub-System which could be attached to an existing computerised data processing system in order to enhance its overall operation. It draws heavily on the experience of the authors in designing a system to assist in the scheduling of video tape machines within BBC Television. 相似文献

Recent research in urban sociology posits that the proliferation of female-headed families in American cities is a result of declining economic prospects due to profound changes in the structure of the urban economy. Meanwhile, macro-level theory and research in criminology suggest that an association exists between family structure and rates of lethal violence among juveniles. Given these two streams of sociological thought, there is good reason to expect that increases in juvenile homicide rates since 1970 may be due, in part, to changes in the structure of the economy and the family during the 1970 to 1990 period. However, the nexus between deindustrialization, female-headed families, and juvenile homicide has received little attention in extant research. The objective of the current study is to remedy this gap in the literature by bringing together ideas about deindustrialization and female headship in an attempt to explain city-level changes in Black and White juvenile homicide rates between 1970 and 1990. In particular, the research investigates the hypothesis that a decline in the manufacturing base of cities increased rates of female headship and thereby indirectly raised homicide rates. Race differences in the hypothesized structural relationships also are examined. 相似文献

This short‐term longitudinal study investigated 918 students' school‐related affect across the transition to high school. The study focused specifically on the moderating effect of change in student ethnic congruence from middle to high school. Results indicate that students experiencing more ethnic incongruence from middle to high school, in particular African American and male students, reported declining feelings of school belonging over time. Moreover, students experiencing ethnic incongruence also had increasing worries about their academic success. These results suggest that the changing school demographics from middle school to high school may negatively impact students' school‐related affect, especially if they move to high schools which include fewer students who are ethnically similar to themselves. 相似文献
