Dr. Dean A. Horn 《The Journal of Technology Transfer》1982,6(2):1-7
A network of 29 Sea Grant Programs now operate in almost all of the 34 eligible coastal and Great Lake states, the Commonwealth of Puerto Rico, and the U.S. Island Territories. Operating in response to current needs and opportunities by applying faculty, research staff and student expertise, Sea Grant Programs have developed many new systems, processes, policy and legal studies, and technologies. These have been effectively transferred to user groups, including major industries, businesses, government agencies, citizen groups and individuals. Many examples of successful technology development and transfer are discussed. Some examples are the hydrodynamic modeling of transport and dispersion of pollutants in large definable water bodies, the demonstration of a prototype machine for skinning the Spiny Dogfish Shark and application of vibration studies to reduce wave response of offshore structures. The examples demonstrate the viability and effectiveness of the Sea Grant concept. 相似文献

Why Don't Housing Choice Voucher Recipients Live Near Better Schools? Insights from Big Data 下载免费PDF全文
Ingrid Gould Ellen Keren Mertens Horn Amy Ellen Schwartz 《Journal of policy analysis and management》2016,35(4):884-905
Housing choice vouchers provide low‐income households with additional income to spend on rental housing in the private market. The assistance vouchers provide is substantial, offering the potential to dramatically expand the neighborhoods—and associated public schools—that low‐income households can reach. However, existing research on the program suggests that housing choice voucher holders live in neighborhoods with schools that are no better than those accessible to other households with similar incomes. Households, in other words, do not seem to spend the additional income provided by the voucher to access better schools. In this analysis we rely on a large‐scale administrative data set to explore why voucher households typically do not live near to better schools, as measured by school‐level proficiency rates. We combine confidential administrative data from the Department of Housing and Urban Development on 1.4 million housing choice voucher holders in 15 states, with school‐level data from 5,841 different school districts, to examine why the average housing voucher holder does not live near to higher‐performing schools than otherwise similar households without vouchers. Specifically, we use the large‐scale administrative data set to test whether voucher holders living in areas with good schools nearby and slack housing markets move toward better schools when schools become salient for them—that is, when their oldest child becomes school eligible. We take advantage of the thick sample of households with young children provided through our administrative data to implement both a household fixed effects and a regression discontinuity design. Together these analyses shed light on whether voucher households are more likely to move toward better schools when schools are most relevant, and how market conditions shape that response. We find that families with vouchers are more likely to move toward a better school in the year before their oldest child meets the eligibility cutoff for kindergarten, suggesting salience matters. Further, the magnitude of the effect is larger in metropolitan areas with a relatively high share of affordable rental units located near high‐performing schools and in neighborhoods in close proximity to higher‐performing schools. Results suggest that, if given the appropriate information and opportunities, more voucher families would move to better schools when their children reach school age. 相似文献

This paper addresses a critical but almost unexamined aspect of the Low Income Housing Tax Credit (LIHTC) program – whether its use (and in particular, the siting of developments in high-poverty/high-minority neighborhoods), is associated with increased racial segregation in the metropolitan area. Using data from the Department of Housing and Urban Development (HUD) and the Census, supplemented with data on the racial composition of LIHTC tenants in three states, we examine three potential channels through which the LIHTC could affect segregation: where LIHTC units are built relative to where other low income households live, who lives in these tax credit developments, and changes in neighborhood racial composition in neighborhoods that receive tax credit projects. The evidence on each of these channels suggests that LIHTC projects do not contribute to increased segregation, even those in high poverty neighborhoods. We find that increases in the use of tax credits are associated with declines in racial segregation at the metropolitan level. 相似文献

This study is concerned with the relationship between witnesses testifying in the Special Court for Sierra Leone and their legal teams. Other research conducted with witnesses in international war crimes tribunals suggests that this relationship has a significant impact on the experience of such witnesses. A structured interview was administered to 171 witnesses who had testified in the Special Court for Sierra Leone. Witnesses generally felt their lawyers' attitude towards them was extremely good. Emotional support and good preparation for testifying seem to be particularly important predictors of witnesses' relationship with their lawyers, as does the level of respect they felt they received from court staff. However, communication between witnesses and their legal teams after the testimony is over did not have a significant impact on witnesses' evaluations of their lawyers' attitude towards them. 相似文献

A 34 years old man shot himself by a selfmade muzzle-loader. He pluged one end of a waterpipe, used a cylindrical lead shot (Cal. 1.2 cm, length 2.15 cm, mass 22.7 g), special black powder (about 4 g, from fire-crackers; powder with an admixture of aluminium) and kindled the weapon in front of his chest by a slowmatch. He died immediately by retained missile of chest. The weapon flew away like a rocket. Unused projectils and powder (found in the flat) and the uninjured pipe allowed to copy the event. Velocity and energy of shot and weapon were determined, also the recoil of the pipe and the highest force of a hand to hold it fast. Experimental investigations and calculations correspondet well to the findings af the case. 相似文献

Ever-scarce affordable housing production resources, in addition to their primary function of providing housing for those in need, are increasingly enlisted for the dual goals of strengthening distressed communities and increasing access to higher opportunity neighborhoods. Information on spillovers can inform investment decisions over time and across communities. We leverage recent, high-quality research on neighborhood effects of Low-Income Housing Tax Credit (LIHTC) production, synthesizing evidence according to neighborhood context. We also summarize the evidence on project features moderating impacts of publicly subsidized, place-based rental housing, in general. We conclude that context matters. Producing LIHTC housing in distressed neighborhoods positively impacts the surrounding neighborhood—in terms of modest property value gains and increased safety. By contrast, higher opportunity neighborhoods experience small property value reductions, and no impacts on crime. Big questions remain, however, about impact heterogeneity—via tenant mix, property design, and ongoing property management, as examples—with the scarcity of systematic data representing one of the field’s largest constraints. 相似文献

The demonstration of congenital heart disease at autopsy necessitates the careful preservation and examination of the heart, the vessels, and their connections. Techniques preserving these connections and using a reproducible and systematic approach are preferred. The Rokitansky method of organ block dissection, in combination with a system of heart examination termed sequential segmental analysis, provides such an approach. This study is based on the examination of heart specimens accessioned into the Frank E. Sherman, M.D., and Cora C. Lenox, M.D., Heart Museum (containing approximately 2400 specimens) of the Pathology Department, Children's Hospital of Pittsburgh. Specimens received in consultation during a 25-year period from hospitals and coroners'/medical examiners' offices were examined, and the corresponding reports were reviewed. Of 46 total heart specimens examined (1975-1999), 29 (63%) were dissected properly or left intact for dissection at Children's Hospital of Pittsburgh, and 17 (37%) were incorrectly dissected for the demonstration of congenital heart disease. Of these 17 cases, 11 (24%) displayed dissection errors, which did not hinder a complete diagnosis, 3 cases (6.5%) had errors that enabled only an incomplete diagnosis, and in 3 cases (6.5%), no diagnosis of congenital heart disease could be made. Dissection mistakes and means of avoiding them are discussed. Review of medical and family history, external and internal examination, and a reproducible and sequential method of examining the heart and its connections enables documentation of even the most complex cardiovascular anomalies. 相似文献
