The increasing availability of urban social indicators offers the possibility of an overall quality of life measure which can be used to compare cities. Several solutions to the problem of combining the individual indicators into an overall comparative measure are considered in this article. The most promising results were obtained by grouping cities according to the similarity of their profiles on the social indicators. Yet the value of the comparisons remains speculative because of serious limitations in the indicators. While a number of improvements are possible, the resulting indicators will still only be adequate for use in gross comparisons of metropolitan areas.  相似文献

Interest in swimming for women during the second half of the nineteenth century was stimulated by the public appearances of professional female natationists who performed in endurance events, exhibited and raced in swimming baths, and displayed ornamental swimming skills in music hall tanks, as well as teaching swimming in female-only classes. This narrative explores briefly the life course of Agnes Beckwith, the ‘London Naiad’, during the last quarter of the century and concludes that individuals like Agnes, who had a lifetime of involvement in all areas of aquatics, contributed significantly to the increasing popularity of the activity among women.  相似文献

Each year, thousands of units are lost from the assisted rental housing inventory through deterioration and default, subsidy expiration, and market-rate conversion. While a good deal of research and data collection has focused on identifying at-risk developments, less is known about what happens to former assisted developments after they exit income and rent restrictions. This article uses a survey of former assisted properties in Florida to identify their postsubsidy trajectories—that is, as to whether developments continue as rental housing, are converted to condominiums, or leave the housing stock through vacancy and demolition; and for those that continue as rental housing, whether they continue to offer affordable rents. Using logistic regression models, the article examines the property, housing market, and neighborhood characteristics that determine these trajectories. The results show that smaller properties, those that have been out of subsidy programs longer, and those in stronger neighborhood housing markets are more likely to be converted to condominiums. Among developments that continue as rental housing, those that previously had more stringent rent restrictions, those in strong rental submarkets, and those with better transit access tend to become unaffordable compared with previous rent limits.  相似文献
