Evolving Location Analytics for Service Coverage Modeling

Among the wide range of geographic analysis methods are service coverage models. These location analytic approaches have been invaluable for better understanding existing (and past) conditions, deriving creative plans, and developing policy for addressing associated societal problems. Increasingly sophisticated spatial information and better knowledge about interrelated mechanisms of process and behavior have made it possible to enhance coverage models, enabling more nuanced formalizations to be devised. This has proven both important and essential in many ways. Mathematical details associated with service coverage models are derived to highlight evolving capabilities. Empirical results are presented in order to illustrate the significance and substantive importance of advanced location analytics capabilities.     

The weight of nineteenth century Mexicans in the Western United States

When traditional methods for measuring economic welfare are scarce or unreliable, heights and BMIs are now well-accepted measurements that represent biological conditions during economic development. Weight, after controlling for height, is an additional measure for current net nutrition. Little is known about how weights varied among Mexicans living in the nineteenth century American West. Between 1870 and 1920, average Mexican weight was low and remained constant. Mexican farmers had the heaviest weights, and unskilled worker weights were low. Weight of Mexican-born individuals were higher than Mexicans born in the United States at low weights but lower at high weights. For combined characteristics, weight varied the most with age, an uncontrollable characteristic, indicating that nineteenth century Mexican current net nutrition varied the most with factors over which they had no control.     

Differing approaches to congressional outreach: comparing Australia and New Zealand

Both Australia and New Zealand, in addition to engaging with the US executive branch, also protect and advance their bilateral relationship by engaging with the US Congress. Since 1987, Australia has pursued congressional outreach, or diplomatic lobbying, to protect and advance its security and trade interests. As a result, Australia has won both security and trade benefits. New Zealand's congressional outreach, on the other hand, has had a more challenging task of improving bilateral relations due, in part, to US objections to New Zealand's anti-nuclear policy. This article extends existing research on Australian and New Zealand congressional outreach, develops a framework for examining embassy-based congressional outreach and, through comparative analysis of Australian and New Zealand congressional outreach, gives greater insight into the nature and character of their efforts on Capitol Hill.     

The Multiple Testing Issue in Geographically Weighted Regression

This article describes the problem of multiple testing within a Geographically Weighted Regression framework and presents a possible solution to the problem which is based on a family‐wise error rate for dependent processes. We compare the solution presented here to other solutions such as the Bonferroni correction and the Byrne, Charlton, and Fotheringham proposal which is based on the Benjamini and Hochberg False Discovery Rate. We conclude that our proposed correction is superior to others and that generally some correction in the conventional t‐test is necessary to avoid false positives in GWR.
