A Nation of Immigrants or a Nation of Immigrant Cities? The Urban Context of Australian Multiculturalism, 1947–2011 下载免费PDF全文
The article documents the urban dimension of Australia's immigration experience that, since the 1940s, has seen the country become one of the world's most multicultural societies. The article argues that the greatest impact of immigration has been in the major cities, especially Sydney and Melbourne, which in recent decades have emerged as internationally‐significant immigrant hubs that, like similar immigrant‐receiving destinations across the globe, are increasingly demographically and culturally distinct from their host nation. Drawing on census materials, oral history interviews, local newspapers and other sources, we chart the demographic transformation of urban Australia from the 1940s to the present day and suggest that these changes have implications for how urban Australians — especially those resident in the two biggest cities — will understand and represent themselves and the nation into the future. 相似文献

Social scientists offer competing theories on what explains the policymaking process. These typically include economic rationalism, political competition or power struggles, and policy imitation of the kind that diffuses across spatially proximate neighbors. In this paper, we examine the factors that have influenced a recent local policy trend in California: inclusionary zoning (IZ). IZ programs require developers to make a certain percentage of the units within their market‐rate residential developments affordable to low‐ or moderate‐income households. By 2007, 68 percent of jurisdictions in the San Francisco Bay Area had adopted some type of IZ policy. We test the relative importance of economic, political, and spatial factors in explaining the rapid diffusion of IZ, across 100 cities and towns in the Bay Area. Consistent with an economic efficiency argument, results of hazard models provide some evidence that IZ is adopted in places with less affordable housing. However, political factors, such as partisan affiliation and the strength of affordable housing nonprofits, are even more robust predictors of whether or not a local government adopts IZ. There is no evidence of spatial diffusion in the case of IZ adoption; jurisdictions are not, on average, responding to the behavior of their neighbors. © 2010 by the Association for Public Policy Analysis and Management. 相似文献

Recreational use of the potent synthetic opioid 3,4‐ dichloro‐N‐(2‐(dimethylamino)cyclohexyl)‐N‐methylbenzamide (U‐47700) is rising, accompanied by increasingly frequent cases of serious intoxication. This article reports a case of near‐fatal U‐47700 intoxication. A man was found unconscious (with drug powder residues). After 40 h in hospital (including 12 h of supported ventilation), he recovered and was discharged. Liquid chromatography/high‐resolution mass spectrometry (LC/HRMS) or gas chromatography/mass spectrometry (GC/MS) were used to detect and quantify substances in powders, serum and urine. Powders contained U‐47700 and two synthetic cannabinoids. Serum and urine were positive for U‐47700 (351.0 ng/mL), citalopram (<LOQ), tetrahydrocannabinol (THC: 3.3 ng/mL), midazolam (<LOQ) and a novel benzodiazepine, clonazolam (6.8 ng/mL) and their metabolites but negative for synthetic cannabinoids. If potent synthetic opioids become cheaper and more easily obtainable than their classical counterparts (e.g., heroin), they will inevitably replace them and users may be exposed to elevated risks of addiction and overdose. 相似文献

The analysis of gamma-hydroxybutyric acid (GHB) is problematic because it is hygroscopic, it lacks a good UV chromophore, and it undergoes heat-induced cyclization. This paper presents a new method utilizing ion-exchange chromatography (IC) with conductivity detection. The simple sample preparation, rapid analysis time, and inorganic anion detection capabilities are all advantages over the current methods. The detection of inorganic salts (formed during GHB synthesis) gives insight into the synthetic route utilized and can aid in drug seizure comparison. The developed method has a detection limit for GHB anions of 0.57 mg/L and chloride of 0.22 mg/L. A comparison of this technique with a current gas chromatography-mass spectrometry technique is presented, and a t-test found that the two methods' results are not statistically different at the 99.9% confidence level demonstrating the merits of this fast, simple, and informative IC method as a routine screening tool. 相似文献

How do economic freedom and culture impact economic growth? This paper argues that culture, as measured by the World Values Surveys, and economic institutions associated with economic freedom are both independently important for economic prosperity, but the strength of their impact can be better understood only when both are included in the growth regression. Our results indicate that economic freedom is more important than culture for growth outcomes, suggesting substitutability between the two. We posit that culture is important for growth when economic freedom is absent, diminishing in significance once economic freedom is established. 相似文献

Gender Differences in the Educational Expectations of Urban,Low-Income African American Youth: The Role of Parents and the School 总被引:2,自引:1,他引:1
This study examined how youths’ gender is related to the educational expectations of urban, low-income African American youth,
their parents, and their teachers. As predicted, African American boys (ages 9–16) reported lower expectations for future
educational attainment than did their female counterparts. Parents and teachers also reported lower expectations for African
American boys (ages 6–16) than for girls. These findings held even when controlling for academic achievement. Contrary to
predictions, the magnitude of the difference in expectations for males vs. females did not increase as a function of youths’
age. In keeping with our hypotheses, parental expectations fully mediated the relation between youths’ gender and youths’
expectations. Finally, certain school-based factors (i.e., positive teacher expectations and positive youth perceptions of
the school environment) appeared to protect youths’ expectations from the deleterious impact of low parental expectations.
