A Comparison of Spatially Varying Regression Coefficient Estimates Using Geographically Weighted and Spatial‐Filter‐Based Techniques

Geographically weighted regression (GWR) is a technique that explores spatial nonstationarity in data‐generating processes by allowing regression coefficients to vary spatially. It is a widely applied technique across domains because it is intuitive and conforms to the well‐understood framework of regression. An alternative method to GWR that has been suggested is spatial filtering, which it has been argued provides a superior alternative to GWR by producing spatially varying regression coefficients that are not correlated with each other and which display less spatial autocorrelation. It is, therefore, worthwhile to examine these claims by comparing the output from both methods. We do this by using simulated data that represent two sets of spatially varying processes and examining how well both techniques replicate the known local parameter values. The article finds no support that spatial filtering produces local parameter estimates with superior properties. The results indicate that the original spatial filtering specification is prone to overfitting and is generally inferior to GWR, while an alternative specification that minimizes the mean square error (MSE) of coefficient estimates produces results that are similar to GWR. However, since we generally do not know the true coefficients, the MSE minimizing specification is impractical for applied research.     

To understand and be understood: facilitating interdisciplinary learning through the promotion of communicative competence

Whilst interdisciplinarity has become a central concern of research and learning in geography, few from the discipline have considered the practical facilitation of interdisciplinarity in the classroom. Module convenors, I argue, must pay greater attention to how learners engage and negotiate with peers and perspectives from other disciplines. In this paper, I focus on my own efforts in designing and teaching a second year undergraduate course on health, biomedicine, and society, to illuminate the opportunities and challenges facing teaching staff who seek to provide opportunities for interdisciplinary learning in the classroom. Drawing upon theories of communication, I demonstrate the significance of developing “communicative competence” as a pathway to successful interdisciplinary learning. Unless learners from one discipline can understand, and be understood by, peers from other disciplines, the accomplishment of interdisciplinary learning is undermined. Interdisciplinary modules should include learning outcomes that facilitate student development in this area. Approaching interdisciplinary learning through the lens of communicative competence casts critical attention upon the central abilities and cultural sensitivities that are the hallmarks of interdisciplinary collaboration – from negotiating meaning to critical disciplinary awareness – and highlights the lessons that interdisciplinarity poses for disciplines, such as geography, tasked with preparing students for interdisciplinary learning.     

Smells like politics: planning and the inconvenient politics of intensive peri‐urban agriculture

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.     

Gendered Archetypes of Wartime Occupation: ‘New Women’ in Occupied North China, 1937–40

This article examines the creation and use of gendered archetypes by the Provisional Government of the Republic of China (PGROC), the first collaborationist government established in China following the Japanese invasion of 1937. Drawing on a wide range of visual sources, it traces how this regime's messages about where women ‘belonged’ in an occupied China resulted in the creation of unique and complex archetypes which were deployed to convince Chinese women of the advantages of PGROC rule. Chief among these archetypes was the figure of the ‘PGROC new woman’. I show how this figure developed in PGROC poster art and propaganda, and eventually in film, as well as how it evolved out of early wartime and pre‐war precedents. In addition to detailing the uses and meanings of this (and other) archetypes, the article suggests that comparative analyses of gendered archetypes of collaboration developed in cognate regimes during the same period can help shed light on the extent to which the peculiar circumstances of wartime collaboration often resulted in specific ideas by male collaborationist leaders about the roles women were expected to play under occupation.     

Lung cancer, chronic disease epidemiology, and medicine, 1948-1964

Beginning in the early 1950s, a series of epidemiological, biochemical, pathological, and animal studies demonstrated a link between cigarette smoking and lung cancer. A number of reputable scientists challenged these findings, but for a variety of reasons, including the behavior of the tobacco industry, historians have assumed that these objections were insubstantial and disingenuous. Viewing these objections in scientific and medical perspective, however, suggests that there was a legitimate and reasonable scientific controversy over cigarette smoking and lung cancer in the 1950s and early 1960s. That controversy had important consequences. A new chronic disease epidemiology emerged, transforming the role and importance of epidemiology to medical research. This new epidemiology supplemented Koch's postulates, establishing a statistical method that allowed for linking environmental factors to the etiology of chronic diseases. The 1964 report to the surgeon general, Smoking and Health, represented the denouement and codification of these developments. This reexamination of the scientific controversy over smoking in the 1950s and early 1960s provides an important context for understanding the subsequent public relations battles between the tobacco industry and public health after 1964.
