DO STATE BUSINESS CLIMATE INDICATORS EXPLAIN RELATIVE ECONOMIC GROWTH AT STATE BORDERS?

This study submits 11 business climate indexes to tests of their ability to predict relative economic performance on either side of state borders. Our results show that most business climate indexes have no ability to predict relative economic growth regardless of how growth is measured. Some are negatively correlated with relative growth. Many are better at reporting past growth than at predicting the future. In the end, the most predictive business climate index is the Grant Thornton Index which was discontinued in 1989.     

Avoiding Disaster: Diversification and Risk Management among East African Herders

This article addresses processes of livelihood diversification among pastoralists in the rangelands of northern Kenya and southern Ethiopia. The objectives of the article are threefold: (1) to suggest a theoretical framework for addressing income diversification among pastoralists with reference to current literature and databases; (2) to present a case study on pastoral income diversification based on preliminary field research in northern Kenya and southern Ethiopia; and (3) to summarize current understandings of pastoral diversification while pointing to additional empirical research needs. By showing how comparative analyses in the region have been constrained by theoretical and data deficiencies, the article explores ways in which income diversification differs by what are termed conditional, opportunity, and local response variables. Climate, distance to market towns, gender, wealth, and education are attributes covered by these variables and discussed in the article. The conceptualization and case study provide useful bases for conducting comparative research on pastoral diversification in East Africa specifically, and in sub‐Saharan Africa generally.     

Roadside Memorials: Interpreting New Deathscapes in Newcastle,New South Wales

Over recent years, roadside memorials to commemorate people killed in motor vehicle accidents have become increasingly noticeable in parts of the Australian landscape. In Newcastle, New South Wales, roadside memorials are placed for young people. The age/gender group most at risk of road death, and those most memorialised, are young men. This is linked to spatially specific constructions of masculinity which circulate within youth milieux of Newcastle. Like other memorials and monuments these ‘deathscapes’ have multiple meanings, differing between those who build, maintain and interpret them. They function as conservative memorials of youth machismo; of heroic aggression, disregard for safety and egocentrism. Roadside memorials need to be re-read as symbolic of societal flaws; of a wasteful road toll, and a testament to dominant and problematic strains of masculinity.

Approximating the Length of Vehicle Routing Problem Solutions Using Complementary Spatial Information

Accurately estimating the length of Vehicle Routing Problem (VRP) distances can inform transportation planning in a wide variety of delivery and service provision contexts. This study extends the work of previous research where multiple linear regression models were used to estimate the average distance of VRP solutions with various customer demands and capacity constraints. This research expands on that approach in two ways: first, the point patterns used in estimation have a wider range of customer clustering or dispersion values as measured by the Average Nearest Neighbor Index (ANNI) as opposed to just using a Poisson or random point process; second, the tour coefficient adjusted by this complementary spatial information is shown to exhibit statistically more accurate estimations. To generate a full range of ANNI values, point patterns were simulated using a Poisson process, a Matern clustering process, and a simple sequential inhibition process to obtain random, clustered, and dispersed point patterns, respectively. The coefficients of independent variables in the models were used to explain how the spatial distributions of customers influence the VRP distances. These results demonstrate that complementary spatial data can be used to improve operational results, a concept that could be applied more broadly.
