Honey bee colony losses are a major concern in the USA and across the globe. Long-term data on losses are critical for putting yearly losses in context. US colony loss surveys have been conducted yearly since the winter of 2006–2007. Here, we report the results from the eighth annual survey on winter losses and the second annual survey of summer and annual(More)
Designing usable geovisualization tools is an emerging problem in GIScience software development. We are often satisfied that a new method provides an innovative window on our data, but functionality alone is insufficient assurance that a tool is applicable to a problem in situ. As extensions of the static methods they evolved from, geovisualization tools(More)
CONTEXT Composed of all or a portion of 13 states, Appalachia is a heterogeneous, economically disadvantaged region of the eastern United States. While mortality from cancer in Appalachia has previously been reported to be elevated, rates of cancer incidence in Appalachia remain unreported. PURPOSE To estimate Appalachian cancer incidence by stage and(More)
Geovisualization is both a process for leveraging the data resources to meet scientific and societal needs and a research field that develops visual methods and tools to support a wide array of geospatial data applications. While researchers have made substantial advances in geovisualization over the past decade, many challenges remain. To support(More)
BACKGROUND It is well established that the incidence of nonmelanoma skin carcinoma is increased in renal transplantation recipients. However, existing studies are not in agreement over whether patients who undergo transplantation have an increased risk of melanoma. The objective of this study was to estimate the risk of melanoma among immunosuppressed renal(More)
Giardia lamblia is a common gastrointestinal pathogen but is not generally appreciated as a cause of severe illness. To describe the epidemiology of severe giardiasis, we reviewed data on hospital discharges from the United States and the state of Michigan and compared results for giardiasis with those for shigellosis. From 1979 to 1988, an estimated 4,600(More)
BACKGROUND Kulldorff's spatial scan statistic and its software implementation - SaTScan - are widely used for detecting and evaluating geographic clusters. However, two issues make using the method and interpreting its results non-trivial: (1) the method lacks cartographic support for understanding the clusters in geographic context and (2) results from the(More)
