Quantitative Analysis of the DNA Distribution on Cigarette Butt Filter Paper*

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.     

Participation in a residential mobility program from the client's perspective: Findings from Gautreaux Two

Abstract

In 2002, the Gautreaux Two housing mobility program provided low‐income families living in Chicago public housing with the opportunity to move to more affluent, less racially isolated communities. This article presents findings on their complex search and moving process. Only about one‐third of enrolled families actually moved through the program ("leased‐up"). In‐depth interviews with a randomly chosen sample of 71 families and an additional 20 “likely mover” families showed that movers fell into four groups distinguished by personal characteristics that made it easier for them to move or by residence on Chicago's North Side.

Nonmovers faced a variety of obstacles, both external (a tight rental market, discrimination, and bureaucratic delays) and internal (limited experience and program comprehension, large household size, and health problems). Also, some nonmovers were too busy with work or school to engage in what proved to be an onerous process of identifying a suitable unit and moving.     

Child characteristics and successful use of housing vouchers: Estimates from the moving to opportunity demonstration

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.     

South Australia's Judicature Act Reforms of 1853: The First Attempt to Fuse Law and Equity in the British Empire

In South Australia in 1853, 20 years before the judicature system was introduced in England, legislation was passed to fuse the administration of law and equity. This article first describes the South Australian reform and then considers the sources from which it might have emanated and the motives behind its enactment. It shows that, however boldly the reform may have been conceived, the practical impact of the reform on the administration of justice in South Australia was very slight. Reasons suggested for this fact include the predominance of English ideas in nineteenth century Australia and the sudden but at the same time voluntary nature of the change introduced by the legislation.
