A Human Centered Geovisualization Framework To Facilitate Visual Exploration Of Telehealth Data: A Case Study, Ashish Joshi, Chiehwen Ed Hsu Nov 2012

A Human Centered Geovisualization Framework To Facilitate Visual Exploration Of Telehealth Data: A Case Study, Ashish Joshi, Chiehwen Ed Hsu

Chiehwen Ed Hsu

Background: Public health data is typically organized by geospatial units. Routine geographic monitoring of health data enables an understanding of the spatial patterns of events in terms of causes and controls. GeoVisualization (GeoVis) allows users to see information hidden both visually and explicitly on a map. Despite the applicability of GeoVis in public health, it is still underused for visualizing public health data. Objective: The objective of this study is to conduct user analysis by examining the various kinds of users that are involved with the telehealth program, their expertise and skills and their perception towards the utilization of GeoVis …

Controlling Influenza A (H1n1) In China: Bayesian Or Frequentist Approach, Dejian Lai, Chiehwen Ed Hsu Jul 2009

Controlling Influenza A (H1n1) In China: Bayesian Or Frequentist Approach, Dejian Lai, Chiehwen Ed Hsu

Chiehwen Ed Hsu

In this article we discuss two approaches to controlling the newly identified influenza A (H1N1) via Bayesian and frequentist statistical reasoning. We reviewed the measures implemented in China as an example to illustrate these two approaches. Since May 2009, China has deployed strict controlling mechanisms based on the strong prior Bayesian assumption that the origin of influenza A (H1N1) was from outside China and as such strict border control would keep the virus from entering China. After more than two months of hard work by Chinese health professionals and officials, the number of confirmed influenza A (H1N1) has increased steadily …
