Abstract This article reports on a reconnaissance of information systems containing data on the beneficiaries of direct and indirect federal housing expenditures. It covers data in the U.S. Departments of Agriculture, Housing and Urban Development, Veterans Affairs, and the Treasury; the Resolution Trust Corporation; financial regulatory agencies; and secondary mortgage market actors. Data varied widely across agencies in availability, accessibility, and quality. Data are more systematically collected for low‐income beneficiaries of housing programs than for the more affluent beneficiaries of indirect housing expenditures. The systems need improvements in data quality and coverage and database format, though they have improved recently. Many research topics can be explored with new and underused data systems: the characteristics of beneficiaries of rural housing programs, urban rental housing programs, low‐income homeownership programs, and mortgage guarantee and insurance programs. But the lack of information on the systems themselves makes data difficult to locate and access. 相似文献

In response to the dramatic rise in the number of unauthorized immigrants to the United States, every state has passed some form of immigration legislation. These laws appear to be predicated on a belief that unauthorized immigrants impose greater costs than benefits to state and local communities, including the labor market. The purpose of this paper is to examine some evidence on what workers should expect if the immigration legislation is successful in eliminating undocumented workers from states' labor markets. © 2012 by the Association for Public Policy Analysis and Management. 相似文献

The Effects of Environmental Exposure on the Optical,Physical, and Chemical Properties of Manufactured Fibers of Natural Origin 下载免费PDF全文

Manufactured fibers derived from natural origins include viscose rayon, azlon, and polylactic acid (PLA). A 2‐year study was conducted to document any changes these fibers undergo as a result of exposure to various environmental conditions. Fabric swatches representing each fiber type were exposed to freshwater, saltwater, heat, cold, ultraviolet light, or composter conditions. Fibers from the swatches were periodically analyzed using polarized light microscopy and Fourier transform infrared microspectroscopy. Fiber solubility and melting‐point behavior were measured every 6 months. Except for the complete degradation of viscose rayon in the composter, saltwater, and freshwater environs, no changes in the optical properties, infrared spectra, solubility, or melting points of the remaining fibers in any of the environments were observed. However, microscopic morphological changes were observed in fibers from two azlon swatches submerged in freshwater and saltwater, two PLA swatches exposed to ultraviolet light, and two viscose rayon swatches exposed to ultraviolet light. 相似文献

ABSTRACTThe article reviews several of the main modalities of India’s human resources’ involvement with other developing economies, and especially those in Africa. These involve the provision of long-term scholarships and short-term professional training awards. Comparison is made, in the case of international students, between the scholarship and privately funded categories, and also between those from Commonwealth and non-Commonwealth countries. Comparable data on such assisted foreign student flows are also offered in respect of South Africa. Other modalities of India’s HRD engagement with Africa are analysed, including those associated with the India-African Forum Summits (IAFS). India also does capacity building through non-state actors, notably nongovernment organisations and the private sector. Furthermore, it promotes cultural diplomacy through its Indian Cultural Centres and Chairs of Indian Studies, though these are not restricted to developing economies. Although attention is paid to the Commonwealth dimension in these comparisons, it is acknowledged that the classification of students and countries as Commonwealth may not be as widespread or meaningful today as 60 years ago. 相似文献
