How can the benefits of housing regeneration programs be sustained?
Formal exit strategies from social housing regeneration
programs assist an estate to become a community by
involving local tenants, developing leadership capacity and
establishing community-run successor organisations
Social Capital and Housing Tenure in an Adelaide Neighbourhood
Author version made available in accordance with publisher copyright policy.In this paper we compare and contrast elements of social capital across different housing tenures in an
Adelaide neighbourhood. Using the results of 530 self-completion questionnaires and in-depth
qualitative interviews with 16 people we assess perceptions of conflict across housing tenures and
between socioeconomic groups, feelings of acceptance and belonging in the local neighbourhood, and
levels of involvement in local formal and informal networks. While only a small number of
questionnaire respondents reported negative views of socioeconomic diversity in the area a common
theme emerging in the qualitative data indicated that housing tenure was relevant to some of these
negative perceptions. Respondents from across different tenure types also reported differences in
feelings of acceptance in the neighbourhood, and involvement in formal and informal networks. The
study findings suggest that housing tenure is relevant to the development of neighbourhood-based
social capital, and that this factor needs to be considered by social planners, housing policy makers and
others involved in implementing social mix policies. In addition, the findings indicate the need to
consider the community housing and public housing tenures in their own right, given the different
models of housing provision, rather than collectively under the common banner of social housing as
most research studies do. It is recommended that the full diversity of housing tenure is considered in
any future analysis

Specific interactions between arbuscular mycorrhizal fungi and plant growth-promoting bacteria--as revealed by different combinations
The interactions between two plant growth promoting rhizobacteria (PGPR), Pseudomonas fluorescens SBW25 and Paenibacillus brasilensis PB177, two arbuscular mycorrhizal (AM) fungi (Glomus mosseae and G. intraradices) and one pathogenic fungus (Microdochium nivale) were investigated on winter wheat (Triticum aestivum cultivar Tarso) in a greenhouse trial. PB177, but not SBW25, had strong inhibitory effects on M. nivale in dual culture plate assays. The results from the greenhouse experiment show very specific interactions; e.g. the two AM fungi react differently when interacting with the same bacteria on plants. G. intraradices (single inoculation or together with SBW25) increased plant dry weight on M. nivale infested plants, suggesting that the pathogenic fungus is counteracted by G. intraradices, but PB177 inhibited this positive effect. This is an example of two completely different reactions between the same AM fungus and two species of bacteria, previously known to enhance plant growth and inhibit pathogens. When searching for plant growth promoting microorganisms it is therefore important to test for the most suitable combination of plant, bacteria and fungi in order to get satisfactory plant growth benefits
PathOrganic – Risks and Recommendations Regarding Human Pathogens in Organic Vegetable Production Chains
PathOrganic assesses risks associated with the consumption of fresh and minimally
processed vegetables due to the prevalence of bacterial human pathogens in plant
produce. The project evaluates whether organic production poses a risk on food safety,
taking into consideration sources of pathogen transmission (e.g. animal manure).
The project also explores whether organic versus conventional production practices
may reduce the risk of pathogen manifestation. In Europe, vegetable-linked outbreaks
are not well investigated. A conceptual model together with novel sampling strategies
and specifically adjusted methods provides the basis for large-scale surveys of organically
grown plant produce in five European countries. Critical control points are
determined and evaluated and factors contributing to a food safety problem are analyzed
in greenhouse and field experiments. The project aims at developing a quantitative
risk assessment model and at formulating recommendations for improving food
safety in organic vegetable production
Tertiary-Treated Municipal Wastewater is a Significant Point Source of Antibiotic Resistance Genes Into Duluth-Superior Harbor
In this study, the impact of tertiary-treated municipal wastewater on the quantity of several antibiotic resistance determinants in Duluth-Superior Harbor was investigated by collecting surface water and sediment samples from 13 locations in Duluth-Superior Harbor, the St. Louis River, and Lake Superior. Quantitative PCR (qPCR) was used to target three different genes encoding resistance to tetracycline (tet(A), tet(X), and tet(W)), the gene encoding the integrase of class 1 integrons (intI1), and total bacterial abundance (16S rRNA genes) as well as total and human fecal contamination levels (16S rRNA genes specific to the genus Bacteroides). The quantities of tet(A), tet(X), tet(W), intI1, total Bacteroides, and human-specific Bacteroides were typically 20-fold higher in the tertiary-treated wastewater than in nearby surface water samples. In contrast, the quantities of these genes in the St. Louis River and Lake Superior were typically below detection. Analysis of sequences of tet(W) gene fragments from four different samples collected throughout the study site supported the conclusion that tertiary-treated municipal wastewater is a point source of resistance genes into Duluth-Superior Harbor. This study demonstrates that the discharge of exceptionally treated municipal wastewater can have a statistically significant effect on the quantities of antibiotic resistance genes in otherwise pristine surface waters
Assessing the impact of area-based initiatives in deprived neighborhoods: The example of S. João de Deus in Porto, Portugal
Though there have been many area-based initiatives to regenerate rundown areas in numerous cities around the world, many of them involving the demolition of stigmatized housing estates, far fewer attempts have been made to assess the effects of these initiatives upon the fortunes of displaced households and those who remain in these areas. By presenting the results of an empirical in-depth case study on the effects of an area-based initiative targeted at one of the most deprived neighborhoods in Porto, this article raises several epistemological concerns related to the goals, ideological assumptions, and social and spatial effects of these initiatives. Among other interrelated issues, the article discusses the impact of conflicting ideologies upon processes of radical strategy shift and of social and territorial marginalization and appeals to the need for more pluralistic approaches to evaluation.I gratefully acknowledge the financial support of the Portuguese Fundação para a Ciência e Tecnologia for research grant SFRH/BPD/75863/2011, POPH/FSE
