The problem of ecological correlation is now widely recognized but detailed analyses of the effects of aggregation on correlation and regression coefficients are rare. A short review of the aggregation problem is followed by an analysis of the specific effect of proximity aggregation on the slope coefficient of a bivariate linear model using data drawn from the Los Angeles Metropolitan region. The evidence suggests that changes in the slope coefficient are best related to the manner in which the covariation between the independent and dependent variables changes with increased aggregation. 相似文献
The spatial and temporal patterns of prices are analyzed over the 1919–40 period. Arguments are made for the distinctiveness of different economic episodes, including the crash of 1929, in terms of their local price effects. Nevertheless, it is also shown that the variability between cities and between components of their price series declined through the early 1940s. Alternative conceptions of spatial price systems are introduced, and due regard is also given to the structure and interpretation of city CPI data. Implications are drawn regarding the proper design of a theory that would explain the observed patterns of spatial price dispersion. This larger project is left, however, to another time. 相似文献
The paradigm concept as developed in western philosophy of science contexts is reviewed, and the metaphysical paradigms that govern research protocols in mainstream Old and New World prehistoric archaeology are described and compared. It is concluded that post-1970 New World archaeological research receives its intellectual mandate from anthropology, is founded on postpositivist biases, and is governed by a critical-realist ontology, a modified-objectivist epistemology, and an experimental-manipulative methodology. Post-1970 Old World archaeological research is viewed as a kind of history, remains mostly in the strict empiricist tradition, and is governed by a realist ontology, an inductivist epistemology, and by an observational methodology. The claims of various kinds of postprocessual archaeology are also evaluated in terms of the paradigm concept. 相似文献
One of the most important questions at the 1919 Paris Peace Conference was what to do about the newly re‐created state of Poland. The Paris peacemakers realised the importance of the settlement, thanks in part to dire warnings about Poland's future, and the leaders spent much time discussing the territorial settlement. Yet discussions of this important question regularly strayed from debates about policy to incorporate understandings of Polish national character. In particular, the leaders of the so‐called Big Three, Britain, France, and the United States, connected expert opinion and the broader political landscape to stereotyped understandings of national character, among other factors. With reference to scholarship on stereotyping, this article analyses how developing attitudes on Polish national character became integrated into the complex settlement of Poland's borders. The peacemakers' decisions, which were a compromise between different points of view, reflected interconnected understandings of the Polish settlement. 相似文献
In the early twentieth century, local British poor law guardians’ concerns with the maintenance of deserted and neglected families were transformed into imperial, and later transnational, policy promoting justice for abandoned wives and children. Both local court cases concerning maintenance and policy debates at the national and imperial levels reveal the ways in which a breadwinner model of masculinity shaped maintenance policy and practice. Although the maintenance problem was framed differently by local welfare providers and imperial heads of state, concerns about welfare costs and human rights intersected in the figure of the irresponsible male citizen, who challenged the dominant model of British/imperial masculinity by refusing to maintain his wife. 相似文献
