Analysis of Building Archetypes for Optimising New Photovoltaic Energy Facilities: A Case Study

Fuel poverty rates are high in southern Europe, particularly in social housing, despite the enormous potential for capturing solar power inherent in the roofs of apartment buildings. The in situ generation, distribution and consumption of photovoltaic energy carry obvious advantages including vastly improved efficiency attendant upon the reduction in distribution-related losses and costs, and the energy empowerment afforded lower income communities. The primary drawback is the imbalance between photovoltaic production patterns and users’ actual needs (peak consumption vs. peak generation). That mismatch is difficult to reconcile without resorting to energy storage or net metering, both of which entail grid involvement and greater management complexity. The present study introduces a methodology for analysing residential archetypes to determine the values of the parameters essential to optimising photovoltaic energy production and use. The aim is to determine where excess generation can be shared with other users in the vicinity and optimally pool residential rooftop facilities to meet community-scale energy demand, ultimately enhancing such disadvantaged neighbourhoods’ self-sufficiency. The case study discussed defines archetypes for just such a neighbourhood in Madrid, Spain. The solar energy production potential of the example is promising for its application in large southern European cities, with self-sufficiency rates obtained ranging from 15% to 25% and self-consumption rates from 61% to 80%.

The changing retail landscape for tobacco: dollar stores and the availability of cheap cigarettes among tobacco-related priority populations

IntroductionDollar stores are rapidly altering the retail landscape for tobacco. Two of the three largest chains sell tobacco products in more than 24 000 stores across the USA. We sought to examine whether dollar stores are more likely to be located in disadvantaged neighbourhoods and whether dollar stores charge less for cigarettes than other tobacco retailers.MethodsData were collected from a statewide random sample of licensed tobacco retailers in California (n=7678) in 2019. Logistic regression modelled odds of a census tract containing at least one dollar store as a function of tract demographics. Linear mixed models compared price of the cheapest cigarette pack by store type, controlling for tract demographics.ResultsCensus tracts with lower median household income, rural status and higher proportions of school-age youth were more likely to contain at least one dollar store. The cheapest cigarette pack cost less in dollar stores compared with all store types examined except tobacco shops. Estimated price differences ranged from $0.32 (95% CI: 0.14 to 0.51) more in liquor stores and $0.39 (95% CI: 0.22 to 0.57) more in convenience stores, to $0.82 (95% CI: 0.64 to 1.01) more in small markets and $1.86 (95% CI: 1.61 to 2.11) more in stores classified as ‘other’.ConclusionsDollar stores may exacerbate smoking-related inequities by contributing to the availability of cheaper cigarettes in neighbourhoods that are lower income, rural and have greater proportions of youth. Pro-equity retail policies, such as minimum price laws and density reduction policies, could mitigate the health consequences of dollar stores’ rapid expansion.

Internal migration industries: Shaping the housing options for refugees at the local level

In this article, we focus on ways in which ‘internal migration industries’ shape the housing location of refugees in cities. Based on empirical studies in Halle, Schwerin, Berlin, Stuttgart and Dresden, we bring two issues together. First, we show how a specific financialised accumulation model of renting out privatised public housing stock to disadvantaged parts of the population has emerged that increasingly targets migrant tenants. With the growing immigration of refugees to Germany since 2015, this model has intensified. Second, we discuss how access to housing is formed by informal agents. While housing is almost inaccessible for households on social welfare, the situation is even worse for refugees. This situation has given rise to a new ‘shadow economy’ for housing that offers services with dubious quality for excessive fees. Bringing these two issues together, we argue that housing provision to refugees has become a new business opportunity. This has given rise to a broad variety of ‘internal migration industries’ that provide the housing infrastructure, but also control access to housing. This not only results in new opportunities for profit extraction, but actively shapes new patterns of segregation and the concentration of refugees in particular types of disadvantaged neighbourhoods.

1461Neighbourhood disadvantage and early childhood mental health inequities across a population of children at school-entry

Background Mental health inequities are shaped by the environments where children develop, including neighbourhoods. Children living in disadvantaged neighbourhoods tend to have poorer development outcomes, yet little evidence has examined positive mental health outcomes, like competence, in young children. Methods We examined associations between neighbourhood disadvantage and young children’s competence, as well as mental health difficulties (internalising and externalising), holding constant demographic characteristics and maternal education using multilevel logistic regression (Markov Chain Monte Carlo estimation). Data were from the 2018 Australian Early Development Census, including over 250,000 children entering their first year of school (age approximately 5 years). Results Children living in Australia’s most disadvantaged neighbourhoods had higher odds of externalising difficulties (AOR: 1.34; 95% credible interval 1.29 to 1.38), internalising difficulties (AOR: 1.29; 95% credible interval 1.24 to 1.33), and lower odds of competence (AOR: 0.72; 95% credible interval 0.69 to 0.74) than children in the least disadvantaged neighbourhoods. Conclusions Across both mental health difficulties and competence, neighbourhood-level inequities were evident. Future research should identify specific neighbourhood features that could address these inequities. Availability of population linked geospatial and child development data in Australia offers opportunities to address these gaps and is prioritised as the next step in this research program. Key messages Children in disadvantaged neighbourhoods face lower likelihood of positive mental health (competence) and higher likelihood of mental health difficulties. Identifying specific neighbourhood features that could address these inequities is a priority.

“Red Vienna” and the rise of the populist right

While research on the spatial variation in populist right voting focuses on the role of “places left behind”, this paper examines the spatial distribution of populist right voting in one of the fastest growing capital cities of Europe, Vienna. Combining detailed electoral data of the 2017 national elections at the statistical ward level and the location of municipal housing units, the paper examines why the populist right “Austrian Freedom Party” (FPOE) performs better in the former bulwarks of socialism, in the municipal housing areas of “Red Vienna”. The paper links the socio-demographic development of Vienna and its municipal housing policy with election results and explores three possible reasons for elevated FPOE shares in municipal housing areas: rising housing costs pushed an increasing number of socially and economically vulnerable into the municipal housing sector and so increased the FPOE voter pool in those areas; European Union accession and changes in regulation allowed foreign citizens to apply to and obtain municipal housing flats triggering a backlash from Austrian municipal housing residents; and municipal housing is located in disadvantaged neighbourhoods further enhancing the FPOE voter pool. The paper demonstrates that higher FPOE vote shares in areas with high municipal housing shares are due primarily to higher shares of formally less educated residents, neighbourhood context and they are marginally elevated in those municipal housing areas experiencing a larger influx of foreign residents.

Report: Covering disadvantaged neighbourhoods

Residents of Toronto's poorest neighbourhoods sometimes accuse the media of only reporting bad news. Is this true? And if it is true, does this matter? A new study in the Canadian Journal of Urban Research analyzes the impact local news coverage has on 13 troubled communities where social services are inadequate and poverty is rising.

‘Notorious Schools’ in ‘Notorious Places’? Exploring the Connectedness of Urban and Educational Segregation

While the statistical link between residential and school segregation is well-demonstrated, in-depth knowledge of the processes or mediating mechanisms which affect the interconnectedness of the two phenomena is still limited. By focusing on well-functioning schools in disadvantaged neighbourhoods, our article seeks to scrutinise whether reputation can be one of the key mediators of the connection between residential and school segregation. Our study combines qualitative ethnographic interviews from four (pre-)primary schools with quantitative segregation measures in four urban neighbourhoods in the Finnish capital city of Helsinki to understand the connections between lived experiences and socio-spatial segregation. The results show that there appears to be a clear link between neighbourhood and school reputation, as schools in disadvantaged neighbourhoods are strongly viewed through the perceptions attached to the place. Despite the case schools’ excellent institutional quality and high overall performance in educational outcomes, there is a consistent pattern of the schools struggling with negative views about the neighbourhoods, which seep into the schools’ reputation. Since school reputation is one of the central drivers of school choices and is also linked to residential choices, the close connection between neighbourhood and school reputation may feed into vicious circles of segregation operating through schools. The results highlight the need for integrated urban policies that are sensitive to issues concerning school reputation and support the confidence and identity of pupils, reaching beyond simply ensuring the institutional quality of schools.

Patterns and Predictors of Sitting among Women from Disad-Vantaged Neighbourhoods over Time: A 5-Year Prospective Cohort Study

Background: Our aim was to describe patterns of sitting over time and determine the sociodemographic predictors of sitting over time among women living in socioeconomically disadvantaged neighbourhoods. Methods: Women age between 18 and 45 years (mean = 34.4 ±8.1, n = 4349) reported their sitting time, sociodemographic (e.g., age), and health (e.g., body mass index) three times over 5 years. Linear mixed modelling was used to determine the predictors of change in sitting over time, adjusting for covariates. Results: Mean baseline sitting time was 40.9 h/week, decreasing to 40.1 h/week over five years. Greater sitting time was reported in participants ≤25 years of age, living with obesity, living in urban areas, self-reported poor/fair health, working full-time, with higher education, never married and with no children. Annually, the average sitting time decreased by 0.4 h/week (95% CI; −0.7 to −0.05) in women working full-time but increased by 0.1 h/week (95% CI; −0.2 to 0.6) who were not working. Similarly, annual sitting time decreased by 0.6 h/week (95% CI; −0.2 to 1.3) in women with no children but increased by 0.4 h/week (95% CI; −0.2 to 0.5) and 0.9 h/week (95% CI; 0.3 to 1.3) among those with two and three/more children, respectively. Conclusion: Among disadvantaged women, those not working and with two or more children may be at particular risk for increased sitting time and warrant further attention.
