Demand-Threshold Estimation for Business Activities in Rural Saskatchewan

Historically, a common technique used to assess a community's ability to support various business activities has been demand-threshold estimation. The concept of a demand threshold has been applied at the community level by estimating a relationship between community population and the number of establishments of a particular kind in the community. The approach taken in this research incorporates a spatial dimension (community urban proximity) in addition to community population to estimate demand thresholds. Using a count data technique, demand thresholds are estimated for 27 different business activities found in 584 rural Saskatchewan communities in 1990. Both population and urban proximity are found to be important explanatory variables.     

Scale, causality, complexity and emergence: rethinking scale's ontological significance

Scale remains a pivotal yet highly contentious concept in geography. I survey the lively discussions engaged in recently by many critical/radical geographers regarding the theoretical status of scale. While these discussions have been intellectually fruitful, I argue that much more needs to be said. Drawing from complex systems theory, I argue that scale should be understood as an ontological category essential to understanding causality. Revalorising Aristotle's four categories of cause – formal, final, material and efficient – from two centuries of positivist thinking facilitates this endeavour. Research on the relationship between university-based poultry scientists and the poultry industry illustrates the explanatory potential of poly-scalar analysis.     

Reimagining the City of Fire and Iron: A landscape archaeology of the Angkor-Period Industrial Complex of Preah Khan of Kompong Svay,Cambodia (ca. 9th to 13th centuries A.D.)

In the archaeological literature regional centers often receive far less attention than capital regions and the medieval Khmer Empire (ca. 9th to 15th centuries a.d.) is a classic case in point. At its height, the Khmer Empire stretched across much of mainland Southeast Asia, and it remains the most extensive dominion in the history of the region. To date, however, relatively little archaeological work has been completed outside of the capital of Angkor, and we have a limited understanding of the broader dynamics of the Empire. In this paper we begin to address this lacuna at the remote monumental complex of Preah Khan of Kompong Svay, the largest of all the Angkor-period regional centers. We describe the use of remote sensing and ground survey methods to produce the first comprehensive archaeological map of the site. The map data are used to evaluate conventional interpretations of the site as a major industrial complex, urban center and military outpost. The findings have implications for our understanding of early urbanism, industrial production and imperial expansion in the region.     

The Diversity We Are Given: Community Economies and the Promise of Bataille

For over 20 years J K Gibson‐Graham and the Community Economies Collective have endeavoured to reveal the diversity of economic practice already operative in our so‐called capitalist world. The aim of this paper is to further this ambition by illuminating an occlusion in Gibson‐Graham's own political vision. It argues that diversity, in Gibson‐Graham's thought, is primarily conceptualised as something produced. Drawing upon the work of George Bataille, this paper conceptualises the economy as a superlative and prodigal system of energy exchange that, by definition, is over‐productive and wasteful. In this framing, diversity is not the result of positive relations but emerges from the prolific nature of the general economy. The idea is developed through a discussion of the Detroit urban farming movement. Specifically it argues that the inefficient, redundant and wasteful nature of urban farming is an appropriation of potentialities resident within the general economy.     

State Taxation, Exploration, and Production in the U.S. Oil Industry

Abstract How do firms in nonrenewable resource industries respond to changes in state taxes? This paper presents simulations of changes in state production (severance) tax policy on the timing of exploration and output in Wyoming. The framework developed allows for interactions between taxes levied by different levels of government. Results suggest that oil production is highly inelastic with respect to changes in production taxes. Policy implications suggest that increases in production taxes on oil risk little loss in future production. The extent to which these results may generalize to other oil producing states is considered. JEL Codes: H71, Q32     

Australian children's independent mobility levels: secondary analyses of cross-sectional data between 1991 and 2012

This study investigated changes in Australian children's independent mobility levels between1991 and 2012. Data from five cross-sectional studies conducted in 1991, 1993, 2010, 2011 and 2012 were analysed. Parent and child surveys were used to assess parental licences for independent mobility and actual independent mobility behaviour in children aged 8–13 years. Findings show declines in the proportion of young children (≤10 years of age) being allowed to travel home from school alone (1991: 68%, 1993: 50%, 2010: 43%, 2011: 45%, 2012: 31%) and travel on buses alone (1991: 31%, 1993: 15%, 2010: 8%, 2011: 6%, 2012: 9%). Furthermore, the proportion of children travelling independently to school decreased (1991: 61%, 1993: 42%, 2010: 31%, 2011: 32%, 2012: 32%). Significantly fewer girls than boys travelled independently to school at each time point (p?≤?.001). Overall, the findings suggest that Australian children's independent mobility levels declined between 1991 and 2012.     

Commuting, Migration, and Rural-Urban Population Dynamics

Over the past 25 years social scientists attempting to explain the dramatic changes in the relative distribution of urban and rural population growth have gravitated toward two competing explanations. The regional restructuring hypothesis holds that changes in the spatial distribution of employment opportunities have been dominant whereas the deconcentration hypothesis attributes these changes to changes in residential preferences of workers and consumers. We develop an empirical test of these two explanations based on whether commuting and migration are positively or negatively related after controlling for other economic factors. Our econometric results support the deconcentration hypothesis.
