Needles In A Haystack: How Pooling Can Control Error Rates In Noisy Tests, Arockia David Roy Kulandai, J. Stella, John Rose, Thomas Schwarz

Computer Science Faculty Research and Publications

Testing many individuals for a reasonably rare condition using imperfect, time consuming, and expensive tests can be facilitated by pooling. Pooling groups samples from different individuals that are then tested for the existence of a pathogen. An individual is diagnosed as a carrier if a threshold of the tests to which the individual contributed samples is positive. Our assumptions dictate a testing strategy that is not adaptive, with the exception of retesting positively diagnosed persons individually. Pooling is a standard proposal to stretch the supply of test kits. We show that it can also be used to control the false …

Divide And Conquer: A Hygienic, Efficient, And Reliable Assembly-Line For Housekeeping, Xiao Alison Chen, Rowan Wang, Jianghua Zhang

Research Collection Lee Kong Chian School Of Business

Problem definition: This work focuses on the hotel housekeeping process. In a field study, a possible channel of disease transmission between consecutive guests in hotel rooms is revealed. In order to prevent the transmission, an innovative assembly-line housekeeping method is developed. Academic/practical relevance: The transmission of infectious diseases during hotel stays (e.g., by touching unclean towels or bed linens) has been reported globally. Under the current COVID-19 pandemic, having contact with saliva or mucus left by an infected person could cause infection. The standard housekeeping process used by the majority of hotels leaves a channel for new towels and bed …

Community Healthcare Clinic - Adaptation System To The Pandemic And Post Pandemic Periods, Nhu Le

Masters Theses

Due to COVID-19, uncertainties and significant changes have been occurring around the world, especially in the U.S. The future is always ambiguous but it will lead to breakthroughs. Emerging issues are the vulnerability of previous conventional design solutions, especially of the healthcare-related architecture and urban planning.

This thesis focuses on helping construct a new healthcare system, which could be used during either a pandemic or post-pandemic era, by designing a local community clinic. In fact, public health clinics are always needed and expected to be more flexibly adjustable and up-gradable. Those new clinics play a very important role since the …

Balance The Conversations, Karen Kuo

Masters Theses

This thesis aims to examine the role environmental factors play in people’s experience of the built environment, with a focus on the ongoing debate between individual freedom and collective responsibility of masks in the COVID-19 era. This thesis will argue that a middle ground that balances the relationship between individual and collective pursuits is necessary and can potentially be enabled through design. The project will articulate these ideas by using the debate around mask-wearing as a starting point to develop a broader manifesto forshaping the built environment.

During this ongoing global pandemic, we can’t deny that human behavior has been …

Timing Of Surgery Following Sars-Cov-2 Infection: An International Prospective Cohort Study, Covidsurg Collaborative, Globalsurg Collaborative

Faculty, Staff and Student Publications

Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 …

The Reset: Connecting Internal Crisis Communication Strategy With Post-Pandemic Remote Worker Populations Through An Employee Engagement Framework, Erin Leigh Black

Doctoral Dissertations and Projects

In the post-pandemic workforce, unprecedented events are the new normal. Although the remote worker revolution has been rumored for decades, in early 2020, the idea became an instant reality when global governments closed their borders, instituted lockdown, and ordered citizens to shelter-in-place (Weideman & Hofmeyr, 2020). Given the global shift in work, organizations have an immediate need to communicate with the crisis-ladened, post-pandemic, remote workforce; however, there is a sizable gap in research between internal crisis communication and the post-pandemic remote worker population. Through a phenomenologically based, interpretive analysis of current strategic and crisis communication research and frameworks, this project …

The Gender Effects Of Covid-19 On Equity Analysts, Frank Weikai Li, Baolian Wang

Research Collection Lee Kong Chian School Of Business

We use the COVID-19 pandemic as a natural experiment to study the effects of childcare and household duties on sell-side analysts. The richness of this setting allows us to compare female and male analysts while requiring them to perform the same tasks. We find that female analysts' forecast accuracy declined more than male analysts, especially when schools were closed and among analysts who were more likely to have young children, inexperienced, were likely busier before the pandemic, and lived in southern states. Female analysts also reduced the timeliness of their forecasts and resorted to more heuristic forecasts. The stock market …

Anti-Intellectualism And American Fears: An Analysis Of Social And Political Factors That Influence Distrust In Scientific Authority, Naomi Hill

Political Science Student Papers and Posters

In the last few decades of our history, strong sentiments of anti-intellectualism and distrust in scientific authority have developed and spread throughout American society. Recently, the outward displays of denial and distrust surrounding the COVID-19 pandemic and climate change have demonstrated just how pervasive these views are becoming. This study looked at public opinion on a variety of anti-intellectual views among the American public. The main question this research was attempting to answer is what are the political and social correlates of anti-intellectualism? The data I used to test this question was the 2021 Chapman University Survey on American Fears. …

Medical Populism And Covid-19 Testing, Kristin Hedges, Gideon Lasco

Peer Reviewed Articles

This paper uses the lens of medical populism to analyze the impact of biocommunicability on COVID-19 testing through a case study approach. The political efficacy of testing is traced through two mini-case studies: the Philippines and the United States. The case studies follow the approach of populism scholars in drawing from various sources that ‘render the populist style visible’ from the tweets and press releases of government officials to media reportage. Using the framework of medical populism, the case studies pay attention to the ways in which coronavirus testing figured in (1) simplification of the pandemic; (2) spectacularization of the …
