conclusions geographic accessibility of pharmacies at night and on holidays has to be addressed by provincial health policymakers. materials and methods the analysis was based on straight-line distance measurements. we considered 150, 300, 450, 600, and 750 m for pedestrians, and 1, 2, and 3 km for driving accessibility as the acceptable distances. we calculated the number and percentage of hou...

Choropleth maps are commonly used in cancer reports and community discussions about cancer rates. Cancer registries increasingly use geographic information system techniques. The Centers for Disease Control and Prevention's Division of Cancer Prevention and Control convened a Map Work Group to help guide application of geographic information systems mapping techniques and to promote choropleth ...

Although lymphatic filariasis is known to have been endemic in Haiti since at least the mid 1700s, a national filariasis survey has never been conducted. As a first step in the national program to eliminate filariasis, we collected blood in January-April 2001 from 50-250 school children (6-11 years old) in all 133 communes of the country using an adaptation of the lot quality assurance sampling...

Average consanguinity (alpha) of 20 large regional or national samples derived from Roman Catholic Dispensations or state archives shows a strong negative relationship with latitude (r = -0.738; P less than 0.001) which seems best explained by cultural-historical factors. Isolates show no such pattern and are more variable in their inbreeding levels. Two-way analysis of variance shows the sampl...

In order to address classic questions about democratic representation in countries with winner-take-all electoral districts, it is necessary to understand the distribution of political preferences across districts. Recent formal theory literature has contributed new insights into how parties choose platforms in countries with a continuum of heterogeneous districts. Meanwhile, increases in surve...

We used ecologic niche modeling of outbreaks and sporadic cases of filovirus-associated hemorrhagic fever (HF) to provide a large-scale perspective on the geographic and ecologic distributions of Ebola and Marburg viruses. We predicted that filovirus would occur across the Afrotropics: Ebola HF in the humid rain forests of central and western Africa, and Marburg HF in the drier and more open ar...

This thesis presents methods, techniques and tools for developing three-dimensional representations of tactical intelligence assessments. Techniques from GIScience are combined with crime mapping methods. The range of methods applied in this study provides spatiotemporal GIS analysis as well as 3D geovisualisation and GIS programming. The work presents methods to enhance digital three-dimension...

The traditional and age-old system of intelligence and criminal record maintenance has failed to live up to the requirements of the existing crime scenario. Manual processes neither provide accurate, reliable and comprehensive data round the clock nor does it help in trend prediction and decision support. It also results in lower productivity and ineffective utilisation of manpower. The solutio...
