Comment on William G. Grigsby and Steven C. Bourassa's “Section 8: The time for fundamental program change?”

Abstract

Grigsby and Bourassa claim that the major problems with the housing voucher program are that most families with affordability problems are not served and that housing assistance is not part of the federal safety net. They propose replacing the program with a housing entitlement for most very low‐income renters, with eligibility linked to receipt of safety‐net benefits. Resources to serve additional families would be generated in part by changes like those found in the Department of Housing and Urban Development's recent block grant proposals.

The Grigsby‐Bourassa proposal lacks a clear assessment of likely costs. Also, there is a risk that the means the authors propose will be heard, but that their call for expansion will not. Finally, their proposal does not intersect with other ideas to modify a basically successful program to better achieve its goals, and questions about rental markets and family and landlord behavior also must be answered.     

Privatizing Urban Services Through Homeowners Associations: The Potential and Practice in Phoenix

Homeowners associations (HOAs) are private nonprofit corporations that regulate, “tax,” and provide urban services to growing numbers of U.S. residents. As such, HOAs may affect cities' public service delivery. Interviews with department heads in Phoenix, Arizona reveal how enclaves of private services influence the city's planning and provision of public services. The findings suggest that HOAs do not substitute private for public services in Phoenix. Instead, qualitative differences in the services themselves (particularly concerning their purpose and scale) and in the legal powers of their providers create a more nuanced pattern of public-private service delivery.     

Stakeholders,natural resource management and Australian rural local governments: A Q methodological study

This paper reports on a Q methodological study of stakeholder perceptions of rural local government management of natural resources. Data analysis of the Q sorts revealed that there are five distinct stakeholder perspectives relating to rural local government and natural resource management. In terms of natural resource management at the local level rural stakeholders perceive local government as an unwilling participant, an inconsequential participant, as a problematic participant, as a potential participant, and, most positively, a participatory partner. The paper describes each of these five stakeholder perspectives in detail before examining the implications of these findings for greater natural resource management at the local level in non-metropolitan Australia.     

Forensic Identification of Indian Snakeroot (Rauvolfia serpentina Benth. ex Kurz) Using DNA Barcoding

Indian snakeroot (Rauvolfia serpentina) is a valuable forest product, root extracts of which are used as an antihypertensive drug. Increasing demand led to overharvesting in the wild. Control of international trade is hampered by the inability to identify root samples to the species level. We therefore evaluated the potential of molecular identification by searching for species‐specific DNA polymorphisms. We found two species‐specific indels in the rps16 intron region for R. serpentina. Our DNA barcoding method was tested for its specificity, reproducibility, sensitivity and stability. We included samples of various tissues and ages, which had been treated differently for preservation. DNA extractions were tested in a range of amplification settings and dilutions. Species‐specific rps16 intron sequences were obtained from 79 herbarium accessions and one confiscated root, encompassing 39 different species. Our results demonstrate that molecular analysis provides new perspectives for forensic identification of Indian snakeroot.     

Forensic Identification of CITES Protected Slimming Cactus (Hoodia) Using DNA Barcoding

Slimming cactus (Hoodia), found only in southwestern Africa, is a well‐known herbal product for losing weight. Consequently, Hoodia extracts are sought‐after worldwide despite a CITES Appendix II status. The failure to eradicate illegal trade is due to problems with detecting and identifying Hoodia using morphological and chemical characters. Our aim was to evaluate the potential of molecular identification of Hoodia based on DNA barcoding. Screening of nrITS1 and psbA‐trnH DNA sequences from 26 accessions of Ceropegieae resulted in successful identification, while conventional chemical profiling using DLI‐MS led to inaccurate detection and identification of Hoodia. The presence of Hoodia in herbal products was also successfully established using DNA sequences. A validation procedure of our DNA barcoding protocol demonstrated its robustness to changes in PCR conditions. We conclude that DNA barcoding is an effective tool for Hoodia detection and identification which can contribute to preventing illegal trade.

Improved detection of semen by use of direct acid phosphatase testing

Acid phosphatase (AP) reagent (Fast Black) is used as a presumptive test for the presence of seminal fluid on exhibits submitted in allegations of sexual assault. Research was carried out to determine whether the direct application of AP reagent to exhibits is a viable alternative to the traditional indirect (blot) testing method used routinely in the laboratory. The relative sensitivity of the indirect and direct testing methods was investigated as was the effect of AP reagent on histological staining of spermatozoa, the incidence of false positives from vaginal material and saliva, and the effect of AP reagent on subsequent DNA testing. Also included are the results of specificity studies from validations of the direct AP testing method. The results of this research show that, provided the incidence of false positives is borne in mind, direct AP testing can be especially useful when screening exhibits which are difficult to indirectly (blot) AP test or when it is problematic to relocate an AP positive stain. Direct application of AP reagent can also be beneficial for locating dilute semen stains. Three case examples are given which illustrate the use of direct AP testing in laboratory casework.     

“I Don’t Know Where it is Safe”: Trans Women’s Experiences of Violence

Scholars are only beginning to take account of how trans people experience violence motivated by their gender identity and expression. Based on a series of focus groups and interviews across Canada, this article aims to further this area of inquiry. The fear of victimization, and thus hyper-vigilance, seems to be particularly acute among trans women. Many of them spoke of the multiple and complex layers through which they defined “safety” and lack thereof. We share their experiences and perceptions of the threat of hate motivated violence, and their subsequent reactions.     

Neighborhood factors related to the likelihood of successful informal social control efforts

Purpose

To expand conceptualizations of informal social control in social disorganization and collective efficacy theories to include responses to informal social control, and to examine neighborhood level predictors of responses to informal social control.

Methods

The study uses surveys of approximately 2300 residents across 66 neighborhoods, supplemented with census data at the block group level.

Results

Neighborhood mobility decreased the odds of positive responses to informal social control, measured as both “giving in” and “talking it out” when you have a disagreement with your neighbor. Disadvantage was found to decrease only the odds of “giving in.” Neighborhood level measures of social cohesion and faith in the police were also found to increase the odds of responding positively to informal social control efforts. In contrast, social ties were not found to significantly affect the likelihood of positive responses to informal social control.

Conclusions

The findings from this study broaden support of collective efficacy theory and concepts related to efficacious neighborhoods. While previous studies have raised questions about the measurement of informal social control, the findings in this paper offer support to earlier studies by providing a different approach to the conceptualization and measurement of informal social control.     

Identification of Crystals Forming on Porcine Articular Cartilage: A New Method for the Estimation of the Postmortem Interval

Articular cartilage was examined to determine its decomposition sequence and its potential for assessing the postmortem interval. Scanning electron microscopy of articular cartilage from buried porcine trotters showed the presence of microcrystals on the synovial surface. These orthorhombic pyramidal or “coffin”‐shaped crystals, appeared at 3 weeks (22 days) after interment and disappeared after 6 weeks. The disappearance of these crystals was linked to decompositional changes to the integrity of the synovial joint. The formation and disappearance of these crystals was associated with a pH change at the cartilage surface. Scanning electron microscopy–energy‐dispersive X‐ray (SEM‐EDX) analysis showed that the five main elements contained within these crystals were carbon, nitrogen, oxygen, magnesium, and phosphorous. Such elemental analysis suggested the crystals may be struvite (MgNH₄PO₄6(H₂O)). Bacteria cultured from the cartilage synovial surface produced struvite crystals when grown in suitable media and were identified by DNA analysis to be Comamonas sp.
