Social housing allocation, choice and neighbourhood ethnic mix in England

Driven by a concern about the negative side effects of ethnic concentration neighbourhoods, many European governments aim to create more ethnically and socio-economically mixed neighbourhoods. At the same time, housing policy aims to give tenants more choice in how and where they live. The objectives of these two policies might conflict as offering people choice has the potential to increase self-segregation, especially across ethnic groups. This paper studies the effect of choice-based letting on (self) segregation in housing association stock in England. We analyse whether households who let their property under choice-based letting end up in neighbourhoods with different levels of ethnic concentrations than households who are matched to a dwelling using the traditional allocation system. We focus on how the effect of choice-based letting differs for ethnic minority households and non-ethnic minority households. Using unique data on all lettings made in the housing association sector in England in 2006/2007 and an ordered logit regression model we show that ethnic minority households are more likely to let a property in an ethnic concentration neighbourhood than non-ethnic minority households. Ethnic minorities letting their property under choice-based letting are the most likely to accept a dwelling in an ethnic concentration neighbourhood.PostprintPeer reviewe

Neighbourhood choice and neighbourhood reproduction

Although we know a lot about why households choose certain dwellings, we know relatively little about the mechanisms behind their choice of neighbourhood. Most studies of neighbourhood choice focus only on one or two dimensions of neighbourhoods: typically poverty and ethnicity. In this paper we argue that neighbourhoods have multiple dimensions and that models of neighbourhood choice should take these dimensions into account. We propose the use of a conditional logit model. From this approach we can gain insight into the interaction between individual and neighbourhood characteristics which lead to the choice of a particular neighbourhood over alternative destinations. We use Swedish register data to model neighbourhood choice for all households which moved in the city of Uppsala between 1997 and 2006. Our results show that neighbourhood sorting is a highly structured process where households are very likely to choose neighbourhoods where the neighbourhood population matches their own characteristics. We find that income is the most important driver of the sorting process, although ethnicity and other demographic and socioeconomic characteristics play important roles as well.PostprintPeer reviewe

Keys and Notes on the Buprestidae (Coleoptera) of Michigan

The distribution and dates of adult activity for Michigan buprestids are discussed. Keys to the genera and species, as well as host information are presented for 116 species and one subspecies. Information on collecting techniques, illustrations of genitalia of 14 species, and scanning electron micrographs of certain structures useful in species identification are presented and discussed. In addition, Pachyschelus confusus, a new species, is described from bush clover

Carbonisation of biomass-derived chars and the thermal reduction of a graphene oxide sample studied using Raman spectroscopy

Chars and carbonised chars were produced from three different oxygen-rich precursors (Pinus radiata wood, Phormium tenax leaf fibres, and sucrose crystals). These non-graphitisable carbons were analysed with Raman spectroscopy in order to study the nanostructural development which occurs with increasingly severe heat treatments up to approximately 1000 °C. The thermal reduction of a graphene oxide sample was similarly studied, as this is considered to involve the development of nanometre-scale graphene-like domains within a different oxygen-rich precursor. Increasing the heat treatment temperatures used in the charring and carbonisation processes, led to significant changes in a number of parameters measured in the Raman spectra. Correlations based on these parameter changes could have future applications in evaluating various char samples and estimating the heat treatment temperatures employed during their manufacture. After production heat treatment temperatures exceeded 700 °C, the Raman spectra of the carbonised chars appeared to be largely precursor independent. The spectra of these carbonised chars were similar to the spectra obtained from thermally-reduced graphene oxides, especially when compared to a wide range of other carbonaceous materials analysed using this particular methodology. Partial reduction of a graphene oxide sample due to reasonably mild laser exposures during Raman analysis was also observed
