Public Housing Transformation and Crime: Making the Case for Responsible Relocation
The research in this article examines the effect on crime rates of public housing transformation in Atlanta and Chicago, focusing on the neighborhoods receiving households relocated with housing vouchers. Modeling the complex relationship between voucher holder locations and crime, using quarterly data, our analysis found that crime rates fell substantially in neighborhoods with public housing demolition, whereas destination neighborhoods experienced a much lesser effect than popular accounts imply. Nevertheless, on average, negative effects emerge for some neighborhoods with modest or high densities of relocated households compared with conditions in areas without relocated households. Overall, we estimate small net decreases citywide in violent crime over study periods during which crime declined significantly. These findings suggest a need for thoughtful relocation strategies that support both assisted residents and receiving communities
Young adults and disability: transition to independent living?
The study aims to explore young disabled peoples I concerns about independent living, and how they view the source of that independence.
The transition to adulthood poses particular problems for young physically disabled adults and independent living is a widely shared goal. The independent living movement has spearheaded an increasing awareness amongst disabled people of their rights as human beings and citizens and has brought together ideas on independent living and ways of achieving it. The philosophy of independent living is based on four assumptions: that all human life is of value; that anyone, regardless of their impairment, is capable of exerting choices; that people who are disabled by society's reaction to physical, intellectual and sensory impairment and to emotional distress have a right to have control over their lives, with whatever assistance they need to do so; and that disabled people have the right to participate fully in society. Government policy is consonant with the aims of the independent living movement: to keep individuals in the community and to address their needs more appropriately.
This study, which is based upon data from 42 young physically disabled adults uses qualitative methods which were inspired by the ideals of the Emancipatory Research Paradigm. Interviews were in-depth and informal and focussed on the periods before, during, and after transition. The work was conducted from the standpoint of the seven fundamental needs outlined in the social model of disability.
To what extent had the young people achieved independent living? None of the sample had achieved independent living in its fullest sense in terms of employment, independent housing, financial and personal control of assistance, life style, relationships, educational qualifications or transport. A minority had achieved some of these. The majority had low self-esteem and had received inadequate support from families and the education system and had poor employment prospects. Most were reliant on benefits which were insufficient to meet the extra costs associated with disability and few had received support from social services. Most appeared destined for a life on the margins of society

Stable isotopic composition of fossil mammal teeth and environmental change in southwestern South Africa during the Pliocene and Pleistocene
The past 5 million years mark a global change from the warmer, more stable climate of the Pliocene to the initiation of glacial-interglacial cycles during the Pleistocene. Marine core sediment records located off the coast of southwestern Africa indicate aridification and intensified upwelling in the Benguela Current over the Pliocene and Pleistocene. However, few terrestrial records document environmental change in southwestern Africa over this time interval. Here we synthesize new and published carbon and oxygen isotope data of the teeth from large mammals (>6 kg) at Langebaanweg (~5 million years ago, Ma), Elandsfontein (1.0 – 0.6 Ma), and Hoedjiespunt (0.35 – 0.20 Ma), to evaluate environmental change in southwestern Africa between the Pliocene and Pleistocene. The majority of browsing and grazing herbivores from these sites yield enamel 13 C values within the range expected for animals with a pure C3 diet, however some taxa have enamel 13C values that suggest the presence of small amounts C4 grasses at times during the Pleistocene. Considering that significant amounts of C4 grasses require a warm growing season, these results indicate that the winter rainfall zone, characteristic of the region today, could have been in place for the past 5 million years. The average 18O value of the herbivore teeth increases ~4.4‰ between Langebaanweg and Elandsfontein for all taxa except suids. This increase may solely be a function of a change in hydrology between the fluvial system at Langebaanweg and the spring-fed environments at Elandsfontein, or a combination of factors that include depositional context, regional circulation and global climate. However, an increase in regional aridity or global cooling between the early Pliocene and mid-Pleistocene cannot explain the entire increase in enamel 18O values. Spring-fed environments like those at Elandsfontein may have 75 provided critical resources for mammalian fauna in the mid-Pleistocene within an increasingly arid southwestern Africa ecosystem
Stable isotope ecology of Cape dune mole-rats (Bathyergus suillus) from Elandsfontein, South Africa: implications for C4 vegetation and hominin paleobiology in the Cape Floral Region
The archaeological and paleontological records from the west coast of South Africa have potential to provide insights into ecosystem dynamics in the region during the mid Pleistocene. Although the fossil record suggests an ecosystem quite different than that of the region today, we understand little about the ecological factors that contributed to this disparity. The site of Elandsfontein (EFT) dates to between 1.0 and 0.6 million years ago (Ma), preserves in situ lithic and faunal materials found in direct association with each other, and provides the rare opportunity to examine the relationship between hominin behavioural variability and landscape heterogeneity in a winter rainfall ecosystem. In this study, we examine the stable carbon isotopic composition of a large sample (n = 81) of Cape dune mole-rats (Bathyergus suillus) and contemporaneous large mammals (> 6 kg; n = 194) from EFT. We find that δ13C values of B. suillus are significantly different to those of contemporaneous large mammals from EFT indicating a significant presence of plants utilizing the C4 photosynthetic pathway during the mid-Pleistocene, in contrast to present C3 dominated ecosystems along the west coast of South Africa. Additionally, we find that artifact density at EFT localities is positively correlated with δ13C values in B. suillus enamel suggesting that evidence of more intense hominin occupation may be associated with the presence of more C4 vegetation. Lastly, we hypothesize that this unique distribution of vegetation 1) provided abundant resources for both hominin and non-hominin taxa and 2) may have concentrated hominin and animal behavior in certain places on the ancient landscape
The microphytobenthos of Königshafen — spatial and seasonal distribution on a sandy tidal flat
A microphytobenthic species composition of a tidal flat in the northern Wadden Sea was analysed regarding cell numbers and biomass (in carbon units). The three sampling sites differed in tidal inundation from 15 cm to about 90 cm water depth at high tide. The sediment was sandy at all three stations. A cluster analysis revealed a separation of the benthic diatoms into three areas: aNereis-Corophium-belt, a seagrass-bed and theArenicola-flat. Small epipsammic diatoms were most abundant and dominated the microalgal biomass. A microphytobenthic “spring bloom” even started beneath the ice cover of the flat in January. Lowest values of cell numbers and biomass of benthic microalgae were found in summer. Highest values were measured in the uppermost area (Nereis-Corophium-belt), and only here was an autumnal increase of benthic microalgae found. Further cluster analysis within each of the three areas revealed seasonal differences although the majority of species were present all year round. Many species were most abundant in spring, and some showed a bimodal distribution (spring-autumn) in the year of investigatio
