Preparing For “Disease X”: Lessons From Tax And Non-Tax Policy Responses To The Covid-19 Pandemic In Singapore And Australia, Vincent Ooi

Research Collection Yong Pung How School Of Law

During the Covid-19 pandemic, a lack of pre-pandemic planning resulted in sub-optimal policy outcomes. Crucial lessons can be drawn from the experience of Singapore and Australia in the pandemic in implementing various tax and non-tax economic measures; lessons that can help in preparing for the next pandemic (“Disease X”). This article analyses and critically evaluates three main categories of economic measures: direct payments, tax measures and non-tax “other” measures. It finds that direct payment measures such as jobs support had a very significant impact on preserving jobs and supporting the economy. However, eligibility conditions have to be carefully designed for …

Net Effects Of Correlated Determinants Of Health Among U.S. Older Adults, Haomiao Jia, E I. Lubetkin

Publications and Research

Background

The health effect produced by a contributing factor alone may be different from the effect when other interacting factors are present. The effects of a set of contributors, estimated by regression coefficients, may be invalid or inappropriate if some of the predictors are correlated or the model has interaction and nonlinear terms. The net effect (NE) of a given contributing factor is the effect produced by the factor alone, not by other factors due to their correlations with the factor of interest. This study estimated NE of selected determinants of health for U.S. older adults.

Methods

Participants, aged ≥ …

Wildfire Smoke And Public Health: Comparing 2023 Canadian Wildfire Events With Hospital Admissions In Douglas County, Nebraska, Jeremy Poell

Capstone Experience: Master of Public Health

Wildfires are becoming increasingly common in Canada and the United States. Smoke produced from these fires creates a multitude of air pollution constituents that can cause breathing and other health issues for humans, particularly those with asthma and other respiratory conditions. Of these pollutants, PM2.5 (particulate matter that is 2.5 microns or smaller) is particularly problematic as these particles are inhaled deep into lung tissue, where they create inflammation and oxidative stress. Poor air quality can also trigger asthma and respiratory issues, leading to an increase in emergency department admissions for breathing treatments. The goal of this study is to …
