Heterogenous Household Expectations, Consumption Choices And Trust, Justine Guillochon

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters that study household consumption choices over the business cycle, the formation of household expectations and the trust of households in the monetary policy institutions.

Chapter 1: Using scanner data and product-level information, this chapter documents the trend and the cyclicality of the processing level of market-purchased household food consumption over the period 2007 to 2020 in the United States. I unveil a strategy, the processing effort, that households exploit to reduce the price of their basket. This strategy consists in altering their basket composition at business cycle frequencies to purchase less processed foods for …

Loss Of Ovol2 In Triple-Negative Breast Cancer Promotes Fatty Acid Oxidation Fueling Stemness Characteristics, Ruiqi Tong, Ceshi Chen, Zhiming Zhang, Rui Zhang, Huiling Guo, Boan Li

Faculty, Staff and Student Publications

Triple-negative breast cancer (TNBC), the most aggressive subtype of breast cancer, has a poor prognosis and lacks effective treatment strategies. Here, the study discovered that TNBC shows a decreased expression of epithelial transcription factor ovo-like 2 (OVOL2). The loss of OVOL2 promotes fatty acid oxidation (FAO), providing additional energy and NADPH to sustain stemness characteristics, including sphere-forming capacity and tumor initiation. Mechanistically, OVOL2 not only suppressed STAT3 phosphorylation by directly inhibiting JAK transcription but also recruited histone deacetylase 1 (HDAC1) to STAT3, thereby reducing the transcriptional activation of downstream genes carnitine palmitoyltransferase1 (CPT1A and CPT1B). PyVT-Ovol2 knockout mice develop a …

Forecasting Acute Kidney Injury And Resource Utilization In Icu Patients Using Longitudinal, Multimodal Models, Holly Hill, Elmer Bernstam, Ken Chen

Faculty, Staff and Student Publications

Background: Advances in artificial intelligence (AI) have realized the potential of revolutionizing healthcare, such as predicting disease progression via longitudinal inspection of Electronic Health Records (EHRs) and lab tests from patients admitted to Intensive Care Units (ICU). Although substantial literature exists addressing broad subjects, including the prediction of mortality, length-of-stay, and readmission, studies focusing on forecasting Acute Kidney Injury (AKI), specifically dialysis anticipation like Continuous Renal Replacement Therapy (CRRT) are scarce. The technicality of how to implement AI remains elusive.

Objective: This study aims to elucidate the important factors and methods that are required to develop effective predictive models of …

Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response, Jacinth Jia Xin Tan, Chin Hong Tan, Michael W. Kraus

Research Collection School of Social Sciences

Higher resting heart rate variability (HRV)—an index of more flexible response to environmental stressors, including noxious stimuli—has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one’s chronic environments, we propose that chronic exposure to threats captured by one’s subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, …

Weight Misperceptions And Health Management Via Information Nudges, Lanjie Wang, Xuan Zhang, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

Being overweight or obese is a serious public health problem. Misperception of one's own weight status and inertia are major obstacles to weight control. To overcome these two problems, we conduct a randomized controlled trial in which participants are presented with the correct weight category based on their body mass index to remove any weight misperception, and then given six biweekly reminders about healthy diet and physical activity via SMS/email. We find that our intervention reduces individuals’ weight misperception and encourages healthier dietary choices. However, it has little impact on their physical activity. We further show that people who were …

Diabetes Management Of Incarcerated Individuals: Is The Federal Bureau Of Prisons Contributing To Worsening Diabetic Conditions?, Mariam Antony

Journal of the National Association of Administrative Law Judiciary

There are many issues related to noncommunicable disease care in federal prisons, which fall under the management of the U.S. Bureau of Prisons, a federal agency. Although there are many noncommunicable diseases, this comment specifically focuses on diabetes because of its prevalence (how common it is in individuals), especially in incarcerated individuals. Prison and incarceration are not conducive to the management of diabetes because diabetes may not even show symptoms until an individual mismanages the disease for a long time. An individual could first appear normal and then suffer a diabetic emergency, which could lead to consequences like heart attack …

Sensing With Integrity: Responsible Sensor Systems In An Era Of Ai, David Eisenberg

Dissertations

Deep and machine learning now offer immense benefits for consumer choice, decision-making, medicine, mental health and education, smart cities, and intelligent transportation and driver safety. However, as communication and Internet technology further advances, these benefits have the potential to be outweighed by compromises to privacy, personal freedom, consumer trust, and discrimination. While ethical consequences for personal freedom and equity rise from these technological advances, the issue may not be the technology itself but a lack of regulation and policy that allow abuses to occur. A first study examines how emerging sensor-based technologies, limited to only accelerometer and gyroscope data from …

Legally Sanctioned Takings Of Black Children: How Slavery Reverberates In The Modern Child Welfare System, Abigail Mitchell

The Scholar: St. Mary's Law Review on Race and Social Justice

This article explores the link between the taking of Black children from their families perpetrated as part of American slavery and modern takings in the modern family policing system. This article posits that underpinning both systems is a pervasive paternalism that purports to be benevolent but has been weaponized to systematically traumatize Black children and villainize Black parents. This article takes a sweeping historical perspective and connects the same discourse used to justify slavery to that which has permeated the modern family policing system.

Strawberry Nectar Preservation Through Innovative Techniques And Energy Evaluation For High-Pressure Processing, Caterina Scaioli

Theses

Strawberries are universally adored by people of all ages, owing to their richness in vitamins, nutrients, and antioxidants, offering myriad health benefits, including combating free radicals. However, despite their popularity, strawberry juices or nectars are not commonly found in markets due to their delicate structure, which makes them prone to rapid deterioration of their prized qualities and vibrant red color. In the food industry, preventing browning and nutrient deterioration are often the primary challenges faced when processing red juices. Traditional preservation methods, such as pasteurization, are inadequate in maintaining their freshness. The focus of this study is to explore alternative …

Adverse early-life experiences (ELA) affect a majority of the world's children. Whereas the enduring impact of ELA on cognitive and emotional health is established, there are no tools to predict vulnerability to ELA consequences in an individual child. Epigenetic markers including peripheral-cell DNA-methylation profiles may encode ELA and provide predictive outcome markers, yet the interindividual variance of the human genome and rapid changes in DNA methylation in childhood pose significant challenges. Hoping to mitigate these challenges we examined the relation of several ELA dimensions to DNA methylation changes and outcome using a within-subject longitudinal design and a high methylation-change threshold. …

Charting A Path To The Quintuple Aim: Harnessing Ai To Address Social Determinants Of Health, Yash Shah, Zachary Goldberg, Erika Harness, David Nash

College of Population Health Faculty Papers

The Quintuple Aim seeks to improve healthcare by addressing social determinants of health (SDOHs), which are responsible for 70-80% of medical outcomes. SDOH-related concerns have traditionally been addressed through referrals to social workers and community-based organizations (CBOs), but these pathways have had limited success in connecting patients with resources. Given that health inequity is expected to cost the United States nearly USD 300 billion by 2050, new artificial intelligence (AI) technology may aid providers in addressing SDOH. In this commentary, we present our experience with using ChatGPT to obtain SDOH management recommendations for archetypal patients in Philadelphia, PA. ChatGPT identified …
