Disease Mapping And Spatial Regression With Count Data, Jon Wakefield

UW Biostatistics Working Paper Series

In this paper we provide critical reviews of methods suggested for the analysis of aggregate count data in the context of disease mapping and spatial regression. We introduce a new method for picking prior distributions, and propose a number of refinements of previously-used models. We also consider ecological bias, mutual standardization, and choice of both spatial model and prior specification. We analyze male lip cancer incidence data collected in Scotland over the period 1975–1980, and outline a number of problems with previous analyses of these data. A number of recommendations are provided. In disease mapping studies, hierarchical models can provide …

Pyemotes Herfsi (Acari: Pyemotidae), A Mite New To North America As The Cause Of Bite Outbreaks, Alberto B. Broce, Ludek Zurek, James A. Kalisch, Robert Brown, David L. Keith, David Gordon, Janis Goedeke, Cal Welbourn, John Moser, Ronald Ochoa, Eduardo Azziz-Baumgartner, Fuyuen Yip, Jacob Weber

Department of Entomology: Faculty Publications

High incidences of red, itching, and painful welts on people in the midwestern United States led to the discovery of a European species of mite, Pyemotes herfsi (Oudemans) (Acari: Pyemotidae), preying on gall-making midge larvae on oak leaves. The mites' great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.

A Coprological View Of Ancestral Pueblo Cannibalism, Karl Reinhard

Karl Reinhard Publications

As the object of my scientific study, I’ve chosen coprolites. It’s not a common choice, but to a paleonutritionist and archaeoparasitologist, a coprolite—a sample of ancient feces preserved by mineralization or simple drying—is a scientific bonanza. Analysis of coprolites can shed light on both the nutrition of and parasites found in prehistoric cultures. Dietary reconstructions from the analysis of coprolites can inform us about, for example, the origins of modern Native American diabetes. With regard to parasitology; coprolites hold information about the ancient emergence and spread of human infectious disease. Most sensational, however, is the recent role of coprolite analysis …

Semiparametric Latent Variable Regression Models For Spatio-Temporal Modeling Of Mobile Source Particles In The Greater Boston Area, Alexandros Gryparis, Brent A. Coull, Joel Schwartz, Helen H. Suh

Harvard University Biostatistics Working Paper Series

Traffic particle concentrations show considerable spatial variability within a metropolitan area. We consider latent variable semiparametric regression models for modeling the spatial and temporal variability of black carbon and elemental carbon concentrations in the greater Boston area. Measurements of these pollutants, which are markers of traffic particles, were obtained from several individual exposure studies conducted at specific household locations as well as 15 ambient monitoring sites in the city. The models allow for both flexible, nonlinear effects of covariates and for unexplained spatial and temporal variability in exposure. In addition, the different individual exposure studies recorded different surrogates of traffic …

Simple Records Matching Method For Diagnostic And Clinical Datasets Of Patient’S Records, Salvo Reina, Vito M. Reina, Eugenio A. Debbia

COBRA Preprint Series

Several statistical packages, either commercials or open-source, provide many methods for multi-factorial and discriminant analysis; such a software is poorly used by physicians. Appropriate models and tests have to be used pending on the kind of experiment scheme, adequate distribution assumption are needed for variables and parameters and proper data validation have to be verified for historical records. These are but a few of many critical aspects for a robust and trustable data interpretation needed in the Evidence Based Medicine era. Clinicians always wish to be able to quickly interpreter diagnostic records to discriminate, or alternatively correlate, coherent groups of …

Sex-Education And Preventative And Contraceptive Services: Educação-Sexual E Serviços Contraceptivos E Preventativos, Elizabeth M. Ortiz

Independent Study Project (ISP) Collection

Maternal morbidity is one of the leading causes of death amongst women in Latina America. Lack of access to Reproductive Health services has incited a continental epidemic amongst adolescent women - and should be considered a public health crisis. Yet, there is little being done by the governing male bodies to secure access and the Right to Reproductive Health services. This is not only a means of re-enforcing gendered inequalities- but also class, and racial disparities. Reproductive Health in Brazil and Northeastern Brazil in particular, serves as an allegory for socio-economic, gender, ethnic, and racial inequality in the region. The …
