Abstract Voucher‐based programs have become the most common form of housing assistance for low‐income families in the United States, yet only a slim majority of households that are offered vouchers actually move with them. This article uses data from 2,938 households in the Moving to Opportunity demonstration program to examine whether child characteristics influence the probability that a household will successfully use a housing voucher to lease‐up. Our results suggest that while many child characteristics have little bearing on the use of housing vouchers, child health, behavioral, and educational problems, particularly the presence of multiple problems in a household, do have an influence. Households with two or more child problems are 7 percentage points less likely to move than those who have none of these problems or only one. Results suggest that such families may need additional support to benefit from housing vouchers or alternative types of affordable housing units. 相似文献

The diversion of foreign direct investment ( fdi ) flows into developing Asia, from Southeast Asia to China, has renewed doubts about whether Southeast Asia's traditional reliance on fdi has left the region without the local capabilities required to sustain the region's long-term competitiveness. Southeast Asia's industrialisation has involved deepening integration into international production networks, comprising internal exchanges between multinational corporations ( mnc s) and their subsidiaries, affiliates and subcontractors. While indigenous industry has been secondary to Southeast Asian industrialisation, this paper highlights three elements of local technological accumulation and clustering within foreign-dominated export industries: production deepening, co-location of design, engineering and R&D with off-shore manufacturing, and the spatial clustering of mnc s in particular industry segments. Southeast Asian governments have responded to these trends by broadening investment promotion from manufacturing to business services and regional headquarters operations, by targeting incentives and infrastructure development to foster industrial clusters, and by invigorating technical support programmes for local small and medium-sized enterprises ( sme s) in supporting industries. Taken together, these trends suggest that Southeast Asia will remain an important site within multinationals' international production networks. 相似文献

The distribution of DNA on the filter paper of smoked cigarette butts was quantitatively mapped using real‐time quantitative polymerase chain reaction. The filter papers from smoked cigarette butts collected from indoor and outdoor sources were sliced into equal pieces and the amount of DNA on each slice was determined. This study found that the cigarette butt filter papers sliced parallel to the seam of the cigarette had more uniformly distributed DNA on the slices and in most cases, there was enough DNA on each slice to obtain a complete DNA profile. The perpendicular slices had a less uniform pattern of distribution and some slices did not have enough DNA to obtain an interpretable DNA profile. Cigarette butts found indoors also had more DNA per cigarette on average than cigarette butts found outdoors. 相似文献

Why do some states diversify their supreme courts sooner than others? Using original data on the first black and female state supreme court justices, I contend that political and institutional pressures influence when states diversify their high courts. The results suggest that selection systems, institutions affecting turnover, and the appointment of political minorities to the United States Supreme Court are associated with states seating their first black and female justices. The findings have implications for our understanding of the political and institutional circumstances that promote judicial diversity. 相似文献

The objective of this study was to assess whether targeting new gun buyers with a public safety message aimed at improving
gun law awareness can modify gun purchasers’ behaviors. Between May 2007 and September 2008, 2,120 guns were purchased in
two target neighborhoods of the City of Los Angeles. Starting in August 2007, gun buyers initiating transactions on odd-numbered
days received a letter signed by prominent law enforcement officials, indicating that law enforcement had a record of their
gun purchase and that the gun buyer should properly record future transfers of the gun. The letters arrived during buyers’
10-day waiting periods, before they could legally return to the store to collect their new gun. Subsequent gun records were
extracted to assess the letter’s effect on legal secondary sales, reports of stolen guns, and recovery of the gun in a crime.
An intent-to-treat analysis was also conducted as a sensitivity check to remedy a lapse in the letter program between May
and August 2007. The letter appears to have no effect on the legal transfer rate or on the short-term rate of guns subsequently
turning up in a crime. However, we found that the rate at which guns are reported stolen for those who received the letter
is more than twice the rate for those who did not receive the letter (p value = 0.01). Those receiving the letter reported their gun stolen at a rate of 18 guns per 1,000 gun-years and those not
receiving the letter reported their gun stolen at a rate of 7 guns per 1,000 gun-years. Of those receiving the letter, 1.9%
reported their gun stolen during the study period compared to 1.0% for those who did not receive the letter. The percentage
of guns reported stolen in these neighborhoods is high, indicating a high rate of true gun theft, a regular practice of using
stolen-gun reports to separate the gun buyer from future misuse of the gun, or some blend of both. Simple, targeted gun law
awareness campaigns can modify new gun buyers’ behaviors. Additional follow-up or modifications to this initiative might be
needed to impact the rate at which guns enter the illegal gun market and ultimately are recovered in crimes. 相似文献
