A missing link? Network analysis as an empirical approach for critical physical geography

Critical physical geography (CPG) calls for integrative research on material landscapes and the socio-political dynamics of scientific knowledge production. Network analysis, a rich tradition of tools and approaches for analyzing relational information, has seen little use in the CPG literature to date. This represents a fruitful opportunity, as many of CPG's core interests—knowledge politics, histories of scientific concepts, and ecosocial relations—can be effectively analyzed using network techniques. In this article, I argue for adapting network approaches to CPG. First, I provide an overview of various network concepts, approaches, and their origins. I then discuss bibliometric network techniques for “science mapping” including co-word, co-authorship, and citation analyses. Next, I describe discourse network analysis, a recent mixed-method approach from political science. Finally, I discuss overlaps with emerging approaches from qualitative and visual network analysis. In each section, I provide existing and hypothetical examples, as well as software and visualization techniques, that demonstrate how network approaches could add new insights to CPG and related scholarship. Linking CPG with the diverse traditions of network analysis has the potential to produce new empirical understandings and bring the field into conversation with a growing body of research that spans the social sciences, natural sciences, and humanities.     

Contextualizing Welfare's Work Disincentive: The Case of Female-headed Family Poverty

The conventional model of the relationship between welfare incentives and poverty rates holds that welfare payments produce an income-enhancement effect that removes families from poverty until some threshold. Beyond this point increased payments engender a work-disincentive effect resulting in increased rates of poverty. We challenge the model's assumption that poverty levels are a simple and spatially invariant response to welfare incentives, contending instead that local employment conditions may substantially alter the relation. Our reformulation of the conventional modeling approach is based on the expansion method. Specifically, we extend the model to include the effects of local labor-market conditions on the response of poverty levels to welfare incentives. In contesting the invariance assumption, the expansion method allows us to determine where and in what contexts welfare is “work discouraging.” The empirical analysis, which is undertaken at the county level, indicates that welfare payments vary in their influence on poverty rates across different employment contexts. A national map portraying this parameter instability demonstrates that female-family poverty rates are most responsive to welfare assistance in the rural South and least responsive in the metropolitan Northeast. Finally, we examine two sharply contrasting locales to illustrate how poverty is governed by specific employment and welfare characteristics.     

James Buchanan's normative theory of the state

This paper examines James Buchanan's normative theory of the state and in particular his attempt to establish a legitimating linkage between the individual and the state. It begins by outlining Buchanan's consent‐based theory of the state and the distinction he draws between the explanatory and justificatory roles of his theory. It proceeds to examine the role of his conceptual contract as a justificatory argument for existing and proposed political institutions. It finds that while the conceptual contract may provide an account of the contingent rationality of the state, it fails to have normative significance in terms of Buchanan's value individualism and subjectivism. Buchanan has also failed to address some of the problems associated with securing and enforcing contractual agreement. These conclusions point to wider problems with rational choice theories of the emergence of the state.     

A leper in purple: the coronation of Baldwin IV of Jerusalem

Baldwin IV, the leper king of Jerusalem, was one of history's more startling monarchs. His coronation in 1174 has been interpreted as anomalous or, alternatively, as evidence of unique cultural and political trends within the Latin Kingdom of Jerusalem. Inherent in all these evaluations, however, is the unquestioned acceptance that Baldwin was known to be leprous at the time of his coronation. This is an assumption that is supported by neither medical understandings of the disease, nor by a consideration of the evidence that survives from the period. Though clearly suffering from advanced leprosy at the time of his death, there is nothing to suggest that Baldwin's disease could have been diagnosed prior to his taking the throne and so there is no need to consider his coronation as anything other than a conventional one.
