Title: Socio-economic inequality in residential exposure to air pollution and noise
Dr Thomas Verbeek (Department of Sociology, University of Warwick)
Together with a growing empirical evidence on the health effects of environmental impacts, the fair distribution of these impacts across society receives increasing attention. However, today only a limited number of empirical studies exists, with varying results and usually focusing on a single environmental impact. This work presents a spatial data analysis in the city of Ghent (Belgium), combining residential exposure to both air pollution and noise with socio-economic variables and housing variables. Results show that more deprived neighbourhoods, with lower incomes, more unemployment, and a higher percentage of foreign origin people, are more exposed to modelled air pollution, but not to modelled traffic noise. We also found that neighbourhoods with more rental houses, more house moves, a shorter length of residence and lower house prices, bear a higher average exposure to air pollution, and to a much lesser degree to noise. Although the residential exposure variables are based on models and multidimensional analyses might lead to further understanding, the results provide a good starting point for discussions about environmental justice and the need to intervene.

Compensating or compounding effects: Can school attended alleviate the effects of family background on academic achievement?
Dr Jenny Chesters (Melbourne Graduate School of Education, University of Melbourne)
Social mobility via education is one of the cornerstones of the Australian democratic state, however, previous research finds evidence of a strong association between parental education and child’s educational achievement and attainment suggesting that social origin plays an integral role in the achievements of successive generations of Australians. Sociologists draw on a range of theoretical perspectives to explain this association including Bourdieu’s cultural and social capital theories. Using data collected by the Longitudinal Survey of Australian Youth 2009 (LSAY09) project, I examine the associations between student SES, school SES and two outcome variables: PISA score and university enrolment. The results indicate that low SES students attending high SES schools perform better on PISA tests than low SES students attending low SES schools. High SES students attending low SES schools perform less well than their high SES peers attending high SES schools. After controlling for PISA score, low SES students were less likely than their high SES peers to enrol at university.
This seminar is organised in collaboration with the Department of Sociology seminar series.

Reproducible science is easy and difficult: Species Distribution Modelling and the ZOON project
Greg McInerny (Centre for Interdisciplinary Methodologies)
Like many activities in quantitative science, the massive growth in Species Distribution Modelling (SDM) has been fuelled by the increasing availability of modelling software and online data. By interpolating species’ distributions in terms of environmental variables these models are used to understand the determinants of biodiversity patterns and predict their futures across a wide range of pure and applied areas of ecological and evolutionary science. In this talk I will present our work on the ‘ZOON’ R package that enables reproducible approaches to SDM, and that could help solve some of the key controversies surrounding this set of methodologies. By composing SDM workflows from modifiable modules, ZOON allows users to approach SDM as an open science that can be validated and make advances more rapidly. Whilst the software is ‘user friendly’ and makes open and reproducible science ‘easy’, it also makes research much more difficult. Progress requires that we disentangle the traditional analytical, theoretical and methodological concerns of science from the cultural, social and technological drivers that determine how we approach science. Understanding these ‘unscientific’ components of science, and using them to re-design science, could lead us to a more scientific (and reproducible) approach to computational science.

The Fifty American States in Space and Time: Applying Conditionally Autoregressive Models
Dr Jamie Monogan (Department of Political Science, University of Georgia)
This paper makes the argument that spatial conditionally autoregressive (CAR) models in a hierarchical Bayesian framework can be informative for understanding American state politics, or any similar population of border-defined observations. Whenever observations are referenced geographically, there is a good possibility that neighbors' error terms correlate. CAR models can account for this, and can easily be included into a wide range of modeling frameworks. This paper shows how to incorporate this kind of error structure into cross-sectional, panel and event history models with applied examples related to public policy liberalism, public opinion on social policy, and the adoption of education lotteries in the 50 American states. With Monte Carlo analyses, we illustrate that as spatial correlation rises, the CAR model offers efficiency gains relative to standard linear models.
