TESTING SIZE-DENSITY RELATIONSHIPS WITHOUT RATIO-VARIABLES,MULTICOLLINEARITY, LOGARITHMIC TRANSFORMATIONS,OR REGRESSION ANALYSIS*

Using data describing the historical distribution of county seats in the United States, we (1) replicate the traditional ratio-variable test of the size-density law, (2) test a new multivariate, nonratio form of the law, and (3) introduce an alternative method of testing, one which avoids three possible problems in traditional analyses: ratio-variables, multicollinearity, and logarithmic transformation.     

Water Mamas among the Makushi in Guyana

Abstract

This article examines folklore concerning water spirits among the Makushi Amerindians in Guyana. Makushi accounts of spirits called ‘water mamas’—twingram or Tuenkaron in Makushi—associate these beings with white people in both past and present. The case is presented here that this folklore reflects Makushi histories and experiences of European contact, colonialism in Dutch and British Guiana, and ongoing relations with Europeans and other outsiders. The themes of abduction, enticement, capricious wealth, and exotic ‘palaces’ found in stories of water mamas relate to these histories and experiences and inscribe them into the present landscape in Guyana. In addition to describing beliefs in water mamas and examining Makushi histories of interaction with Europeans, the article begins to explore the comparative context of this folklore in relation to other beliefs in water spirits across Amazonia and beyond.     

Institutions,informality, and influence: explaining nuclear cooperation in the Australia-US alliance

ABSTRACT

Nuclear cooperation has been a consistent feature of the Australia-US alliance. In the 1950s and 1960s, Canberra explored transferring US nuclear weapons to Australian forces operating in Southeast Asia. Since the 1960s, Australian governments have supported hosting joint facilities that contribute to America’s ability to execute global nuclear operations. And Australia has regularly invoked the nuclear umbrella as part of the alliance. We explain the key sources of nuclear cooperation in the alliance by leveraging realist and institutionalist theories of alliance cooperation. While realism explains limits to US nuclear commitments in the 1950s, institutional explanations are more relevant in pinpointing the sources of nuclear cooperation and in explaining why Australia has often achieved its policy preferences as the junior partner.     

Prospecting for Economic Returns to Research: Adding Informational Value at the Market Fringe

Abstract.  Private markets constantly assess project investment opportunities across a spectrum of such possibilities. The market's perspective on the boundary of viable projects, however, may be more limited than socially optimal due to informational constraints. In the case of economic development projects in particular, this boundary could be extended by public researchers. This paper constructs a method to estimate the private and social value‐added of such research, providing a new means to understand and assess the public/private sector interface. The framework uses agents' evolving subjective perceptions through Bayesian updating to value research information, along with methods to estimate functional forms and relative optima. Two case studies of regional development research on value‐added agriculture in Colorado highlight the utility of the approach.
