Location efficient mortgage (LEM) programs are an increasingly popular approach to combating urban sprawl. LEMs allow families who want to live in densely populated, transit‐rich communities to obtain a larger mortgage with a smaller down payment than traditional underwriting guidelines allow. LEMs are premised on the proposition that homeowners in such “location‐efficient” areas can safely be allowed to breach underwriting guidelines designed to prevent mortgage default because they have lower than average automobile‐related transportation expenses and more income available for mortgage payments. This paper employs records of more than 8000 FHA‐insured mortgages matched with data on various measures of location efficiency to test this proposition. The results suggest that it does not hold and that LEMs—like other low‐down‐payment mortgage programs—will raise mortgage default rates. This cost must be weighed against any potential anti‐sprawl benefits LEMs may have. © 2001 by the Association for Public Policy Analysis and Management.  相似文献

Prior experimental research has demonstrated that voter turnout rises substantially when people receive mailings that indicate whether they voted in previous elections. This effect suggests that voters are sensitive to whether their compliance with the norm of voting is being monitored. The present study extends this line of research by investigating whether disclosure of past participation has a stronger effect on turnout when it calls attention to a past abstention or a past vote. A sample of 369,211 registered voters who voted in just one of two recent elections were randomly assigned to receive no mail, mail that encouraged them to vote, and mail that both encouraged them to vote and indicated their turnout in one previous election. The latter type of mailing randomly reported either the election in which they voted or the one in which they abstained. Results suggest that mailings disclosing past voting behavior had strong effects on voter turnout and that these effects were significantly enhanced when it disclosed an abstention in a recent election.  相似文献

Mongolia is not a hapless object on which the great powers may act at will. Like other small states existing on the periphery of great powers, Mongolia has—and does exercise—political agency. Its policies and actions affect not only the bilateral relationship it has with each of the greater powers, but—as an outgrowth of those bilateral relations—it also exerts some influence on the relationship that the great powers, in turn, have with each other. “… you know as well as we do that right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must.”1  相似文献

An accurate understanding of the spatial relationships between the deep and superficial structures of the head is essential for anthropological methods concerned with the comparison of faces to skulls (superimposition) or the prediction of faces from them (facial approximation). However, differences of opinion exist concerning: (i) the position of the eyeball in planes other than the anteroposterior plane and (ii) the canthi positions relative to the bony orbital margins. This study attempts to clarify the above relationships by dissection of a small sample of adult human cadavers (N = 4, mean age = 83 years, s = 12 years). The most notable finding was that the eyeballs were not centrally positioned within the orbits as the more recent craniofacial identification literature expounds. Rather, the eyeballs were consistently positioned closer to the orbital roof and lateral orbital wall (by 1-2 mm on average); a finding consistent with the earlier anatomical literature. While these estimation errors are small ipsilaterally, several factors make them meaningful: (i) the orbital region is heavily used for facial recognition; (ii) the width error is doubled because the eyes are bilateral structures; (iii) the eyes are sometimes used to predict/assess other soft tissue facial structures; and (iv) the net error in facial approximation rapidly accumulates with the subsequent prediction of each independent facial feature. While the small sample size of this study limits conclusive generalizations, the new data presented here nonetheless have immediate application to craniofacial identification practice because the results are evidence based. In contrast, metric data have never been published to support the use of the central positioning guideline. Clearly, this study warrants further quantification of the eyeball position in larger samples and preferably of younger individuals.  相似文献

The United States (U.S.) population structure is currently in a state of flux with one of the most profound changes being the increasing number of people referred to as Hispanic. In the U.S., much of the identification criteria for a biological profile are based on American Black and White individuals from anatomical collections. Using metric data from the Forensic Anthropology Data Bank (FDB), this paper will attempt to explore several issues that forensic anthropologists face when confronted with Hispanic remains. These will involve estimation of sex, height, and ancestry, the initial components of a biological profile. Discriminant function analyses indicate that American White criteria provide poor estimations of sex when applied to Hispanics and that ancestry estimation of Hispanic crania is difficult. Additionally, a new linear regression equation is presented that estimates stature for Hispanic individuals, although population specific criteria are still needed for Hispanic individuals from diverse geographical origins.  相似文献

The dissemination of social program innovations that have been demonstrated to be effective through rigorous evaluation is an important issue. The classical dissemination framework emphasizes the position that programs implemented with fidelity to the original model are most likely to produce the positive outcomes demonstrated in the model's evaluation phase. However, critics suggest that local programs that are extensively modified are more likely to meet local goals and, therefore, are more likely to be sustained within the organization. The present research examined the implementation, effectiveness, and routinization of seven innovations replicated in a nationwide sample of organizations. The innovations were diverse in both content and implementing context and were located in a variety of sites, including schools, courts, prisons, police departments, and social service agencies. The results suggest that the innovations were replicated with acceptable levels of fidelity to the disseminated program models, and that higher-fidelity implementations tended to be more effective than those implemented with lower fidelity. The implications of the findings for social program dissemination policy are discussed and the authors propose an expansion of Berman's contingency model of innovation dissemination.  相似文献
