Abstract This article explores target marketing as a means to identify which middle‐income suburbanites may relocate to central cities. The most targetable populations reside near central cities and lead urban lifestyles. We term such people “suburban urbanites.” Geodemography, a method combining population and location, is used to classify suburban urbanites using data from Claritas Inc., a target marketer. Claritas divides the nation's neighborhoods into lifestyle clusters by linking population density to demographic and consumptive patterns. A case study of metropolitan Washington, DC, illustrates how target marketing works. We find that more than half the region's middle‐class, Claritas‐defined urbanites live outside the District of Columbia. Thus, a large market of potential city dwellers lives in Washington's suburbs. Target marketing enhances the statistical approaches traditionally used in policy making and may help cities understand and develop their comparative advantages. 相似文献

This article explores the selective affinities between the study of West European politics and historical institutionalism. We divide the last 30 years into four phases: the foundational ideas of the late 1970s and early 1980s; the evolution of these ideas from structuralism to institutionalism in the late 1980s and early 1990s; more radical revision under the turbulent 1990s and early 2000s; and the future outlook at the end of the first decade of the 2000s. We emphasise the ways in which the field of West European politics has shaped the direction of historical institutionalism as a distinctive approach to the study of politics, particularly historical institutionalism's focus on explaining actors' interests and behaviour. We also discuss recent debates within historical institutionalism concerning the role of history and path dependence, ideas, and institutional origins and change in the context of developments within West European politics. We conclude by discussing several challenges for both historical institutionalism and the study of West European politics: maintaining and improving analytical rigour as politics in Western Europe become even more fluid; continuing to build middle range theory; and extending our comparative analysis of Western Europe to include regions outside of Western Europe. 相似文献

As part of the federal Permanency Innovations Initiative, this local grantee implemented an evidence-based intervention to improve outcomes for children with serious emotional disturbance. The project approach integrates the tenets of implementation science and program evaluation. Formative evaluation used a small sample (n = 76) to assess implementation integrity and statistical association to recommend whether the intervention was ready for summative evaluation (SE). Results showed that most process expectations were met. Statistical findings suggested that the intervention was associated with higher rates of reunification for treatment families as compared to families receiving services-as-usual. Thus, the intervention was recommended for SE. 相似文献

The dominance of social science research in the debate over the Bush Administration’s Healthy Marriage Initiative may explain why questions regarding the proper role of government in regulating adult intimacy have received little attention. Social science research focuses on outcomes such as well-being and health. In contrast, rights-based legal theory considers whether state action undermines the rights of individuals. In this article, I intend to shift the debate over marriage promotion policy from questions of child well-being to questions of individual rights. I will ask the following questions: Do individuals have a liberty interest in making their own choices about intimate relationships, such as marriage? Do federally-financed (and frequently state-run) marriage programs compromise this liberty interest? Are there any constitutional grounds for objecting to marriage promotion policy? 相似文献

ABSTRACT The Joint Africa–EU Strategy (JAES, 2007), aimed to break with the traditional donor-recipient relationship between the EU and Africa and to develop a true partnership. This paper investigates whether the JAES has succeeded in this aim. Particularly, it focuses on the principle of equality, defined as a situation where the more powerful partner does not impose its will on the less powerful partner. Empirically, it investigates the thematic partnerships on peace and security and democratic governance and human rights. Based on a review of primary and secondary literature and 32 expert interviews, the paper argues that the EU has overall treated its African counterparts as equal partners in these thematic partnerships, namely by respecting ownership and jointly deciding on what to discuss in the partnership. Nonetheless, divergences based on differences in interests and values have in some cases led to the perception from African partners that the EU did not treat them as equals. 相似文献

This article argues that a key step in King's iterative approachto R x C ecological inference problemsthe aggregationof groups into broad conglomerate categoriescan introduceproblems of aggregation bias and multimodality into data, inducingmodel violations. As a result, iterative EI estimates can beconsiderably biased, even when the original data conform tothe assumptions of the model. I demonstrate this problem intuitivelyand through simulations, show the conditions under which itis likely to arise, and illustrate it with the example of Colouredvoting during the 1994 elections in South Africa. I then proposean easy fix to the problem, demonstrating the usefulness ofthe fix both through simulations and in the specific South Africancontext. 相似文献

Application of the BioMek 2000 Laboratory Automation Workstation and the DNA IQ System to the extraction of forensic casework samples 总被引:1,自引:0,他引:1

Robotic systems are commonly utilized for the extraction of database samples. However, the application of robotic extraction to forensic casework samples is a more daunting task. Such a system must be versatile enough to accommodate a wide range of samples that may contain greatly varying amounts of DNA, but it must also pose no more risk of contamination than the manual DNA extraction methods. This study demonstrates that the BioMek 2000 Laboratory Automation Workstation, used in combination with the DNA IQ System, is versatile enough to accommodate the wide range of samples typically encountered by a crime laboratory. The use of a silica coated paramagnetic resin, as with the DNA IQ System, facilitates the adaptation of an open well, hands off, robotic system to the extraction of casework samples since no filtration or centrifugation steps are needed. Moreover, the DNA remains tightly coupled to the silica coated paramagnetic resin for the entire process until the elution step. A short pre-extraction incubation step is necessary prior to loading samples onto the robot and it is at this step that most modifications are made to accommodate the different sample types and substrates commonly encountered with forensic evidentiary samples. Sexual assault (mixed stain) samples, cigarette butts, blood stains, buccal swabs, and various tissue samples were successfully extracted with the BioMek 2000 Laboratory Automation Workstation and the DNA IQ System, with no evidence of contamination throughout the extensive validation studies reported here. 相似文献
