This paper presents in-depth case study of a successful hybrid political and community organizing campaign to ensure equitable access to health care through the perspective of a grassroots San Francisco community-based organization, the Chinese Progressive Association (CPA), which has been organizing low-income Chinese immigrants for over four decades. First, it outlines the Health Care Security Ordinance (HCSO), which, since its passage in 2006, has established a near-universal health care access program, helping to make health care accessible and affordable to individuals living and working in San Francisco. Then it presents the campaign to save the HCSO, focusing on CPA’s participation in the HCSO coalition. Finally, it discusses health care as it relates to the San Francisco’s affordability crisis and the political economic context in which it is taking place. Despite the limitations inherent in small case studies like this one, it nevertheless provides a valuable opportunity to better understand how one politically progressive city attempted to address the problem of grossly inequitable health care access through the lens of community organizing, advocacy, and coalition building. San Francisco, like many major American cities today, is being confronted with rapid gentrification and growing economic inequality—the backdrop to the HCSO. Through innovative experiments in social responsibility like the HCSO, however, the city has made leaps in health care access. It concludes with lessons learned from local organizing and advocacy to save the HCSO as these may inform other local efforts to promote health care for all. 相似文献

The Message in Daily Exchange Rates: A Conditional-Variance Tale 总被引:1,自引:0,他引:1
Formal testing procedures confirm the presence of a unit root in the autoregressive polynomial of the univariate time series representation of daily exchange-rate data. The first differences of the logarithms of daily spot rates are approximately uncorrelated through time, and a generalized autoregressive conditional heteroscedasticity model with daily dummy variables and conditionally t-distributed errors is found to provide a good representation to the leptokurtosis and time-dependent conditional heteroscedasticity. The parameter estimates and characteristics of the models are found to be very similar for six different currencies. These apparent stylized facts carry over to weekly, fortnightly, and monthly data in which the degree of leptokurtosis and time-dependent heteroscedasticity is reduced as the length of the sampling interval increases. 相似文献

This article is concerned with the simulation of one‐day cricket matches. Given that only a finite number of outcomes can occur on each ball that is bowled, a discrete generator on a finite set is developed where the outcome probabilities are estimated from historical data involving one‐day international cricket matches. The probabilities depend on the batsman, the bowler, the number of wickets lost, the number of balls bowled and the innings. The proposed simulator appears to do a reasonable job at producing realistic results. The simulator allows investigators to address complex questions involving one‐day cricket matches.

Abstract Social scientists have increasingly come to recognize the informal economy as a prominent and permanent structural feature of modern society. Rural sociologists have made a considerable contribution to this literature, demonstrating informal work to factor prominently in the livelihood strategies of rural Americans. Despite this scholarly attention significant gaps persist in our understanding of the informal economy. Drawing on data from a survey of family households in nonmetropolitan Pennsylvania, this paper examines the contours and correlates of informal work. The results make a strong case that participation in informal work is widespread and most often combined with formal work as a household livelihood strategy. While income is not found to be a significant correlate of informal work, it is found to influence the reasons cited for participation. Important correlates of informal work are identified and differences in the factors associated with informal work done to generate income (cash or in‐kind) versus savings are revealed. 相似文献

The genetic algorithm is examined as a method for solving optimization problems in econometric estimation. It does not restrict either the form or regularity of the objective function, allows a reasonably large parameter space, and does not rely on a point-to-point search. The performance is evaluated through two sets of experiments on standard test problems as well as econometric problems from the literature. First, alternative genetic algorithms that vary over mutation and crossover rates, population sizes, and other features are contrasted. Second, the genetic algorithm is compared to Nelder–Mead simplex, simulated annealing, adaptive random search, and MSCORE. 相似文献

Local social services departments in the UK are expected to distribute their cash-limited budgets for community care in ways that achieve an equitable allocation of resources in situations where, with present levels of funding, they cannot meet all the needs with which they are presented. This paper discusses a case study of the introduction of a "needs-based" formula to allocate a local authority's budget for home care services and a follow-up survey to investigate whether services reached the people intended to benefit. The article argues that the "gatekeeping" role of community care assessments is important to safeguard equity without the inflexibility of highly standardized tests of eligibility. However, with the new Labour government seeking to reduce dependency on public expenditure, and a growing lobby for national standards of social care, it will be increasingly important that local authorities justifiy their different practices with evidence about how they relate to local needs. 相似文献

Brass has proposed a relational Gompertz model of female fertility which, in combination with the standard fertility distribution developed by Booth, has proved useful in a range of applications, such as indirect estimation, demographic modelling, and population projections. This paper develops a standard distribution of male fertility for use in conjunction with the relational Gompertz model. The derivation of the standard takes advantage of the similarity between the shape of male and female fertility distributions. It entails ‘stretching’ the female standard, so that it extends to age 80, and then transforming it, using the Gompertz model into a pattern which is more typical of male fertility distributions in the developing world. An assessment of this new standard by fitting the relational Gompertz model based on it to a series of male fertility distributions from diverse populations, suggests that it performs very well. 相似文献

Following Henri Lefebvre, this article investigates the distinct rhythms of walking and the ways that it intersects with diverse temporalities and spaces. Because walking is practised and experienced in innumerable contexts, generalisations are problematic. Nevertheless, this article identifies some of the ways in which walking produces time-space and the experience of place. I subsequently discuss how walking is inevitably conditioned by multiple forms of regulation but possesses peculiar characteristics that always make these orderings of space and body contingent, facilitating immanent, often unexpected experiences. I further examine how walking is surrounded by notions of style that reproduce particular rhythms. Walking is inevitably, therefore, suffused with contending notions about how and where to walk, by ideals and conventions laid down by the powerful and not-so-powerful. However, I pay attention to the multiple phases and moments of walking. Both the conventions of walking and its unfolding, sensual and contingent apprehension are difficult to elucidate in academic prose, and luckily there are several challenging walking artists whose work highlights these issues and the rhythmic dimensions of walking. Accordingly, I draw upon the ‘textworks’ of Richard Long, Francis Alys's series of walks entitled Railings, and Jeremy Deller's 2009 Procession to elicit some of the rhythms of walking. 相似文献
