Teaching For Global Ecological Citizenship: A Case Study Of Rural Teachers’ Experiences And Practices, Sarah L. Tennyson

Dissertations

The purpose of this qualitative case study is to examine the experiences and practices of rural educators incorporating global ecological citizenship education into the social studies classroom. The systematic themes of social studies education in the past must evolve with the diversity of the classroom. Traditional themes taught must become more globally relevant, including ecological citizenship, the responsibility of citizens to sustain and participate in global ecological issues. One on one interviews with four rural Georgia educators along with artifacts they provided were examined for themes related to two research questions. How do rural educators adapt their instructional strategies to …

Establishing Procedures For Primary Human Myoblast Cell Culture, Erica Duffy

Biomedical Engineering

Peripheral Artery Disease (PAD) affects an estimated 200 million people worldwide and is the leading cause of amputation in the United States. PAD is characterized by atherosclerotic narrowing of arteries, resulting in ischemia from reduced blood flow to distal tissues. Although surgical and percutaneous interventions can restore perfusion, fewer than 50% of patients experience sustained benefit, highlighting the need for alternative therapeutic strategies. One promising approach is promoting arteriogenesis, the growth and outward remodeling of pre-existing collateral vessels that improve blood flow around the occluded arteries. Arteriogenesis is regulated by regenerative, M2-polarized macrophages, making macrophage polarization a key therapeutic target. …

Thermal Management With Supercritical Carbon Dioxide Under Extreme Applications, Devon Hardy

Doctoral Dissertations and Master's Theses

A unique challenge in thermal system design is minimizing the power required to operate cooling systems while maintaining effective heat removal. Traditional cooling systems utilize single-phase fluids where the heat transfer mechanisms are well understood. To meet a variety of cooling demands, a range of technologies are available, including microchannel forced convection, jet impingement, porous media, nanofluids, pin fin arrays, and film cooling, each offering distinct advantages and limitations. While the performance of single- or two-phase cooling systems are generally predictable, in extreme thermal environments, new cooling solutions are needed to improve overall system efficiency and reliability.

Supercritical fluids, particularly …

Riding Attention Spikes: How Analysts Respond To Advertising, Minjae Koo, Annika Yu Wang, Yin Wang, Liandong Zhang

Research Collection School Of Accountancy

Product market advertising, while containing little new information, triggers spikes in investor attention. Using weekly advertising data, we find that sell-side analysts issue optimistic earnings forecasts in response to heavier advertising in the prior week. This effect is not driven by confounding earnings or product news. It is more pronounced for experienced analysts and analysts affiliated with brokerages relying solely on trading revenues. The optimistic forecast bias intensifies the impact of advertising on investor trades, especially on retail buying, of the underlying stock during the following week. Overall, analysts appear to issue optimistic forecasts to exploit retail investor attention spikes …

Over-Reliance On Aesthetics? The Appearance-Reveals-Character Lay Theory Increases Consumers’ Devaluation Of Unattractive Produce, Shilpa Madan, Krishna Savani, Gita Venkataramani Johar

Research Collection Lee Kong Chian School Of Business

Approximately 40% of all produce is rejected because it appears unattractive, contributing significantly to food waste. Whereas previous research attributes this devaluation to the ugly-is-bad effect, this research identifies an important moderator of consumers’ reliance on this heuristic: the lay theory that a person’s outer appearance reveals their inner character. Specifically, consumers who believe that people’s appearances reveal their character are less willing to accept unattractive (vs. attractive) produce because they generalize their lay theory to produce and are, thus, more likely to infer that unattractive produce is of lower quality. Consumers who do not hold the lay theory do …

Incident-Driven Esg Engagements, Hao Liang, Yongheng Sun, T. Mandy Tham

Research Collection Lee Kong Chian School Of Business

We examine when and why institutional investors engage portfolio firms on ESG issues using proprietary engagement records from a European asset manager. Salient negative incidents emerge as a powerful trigger—second only to firm size—because they heighten reputational accountability for investors and reveal new information about hidden ESG weaknesses, particularly at firms perceived as ESG leaders. Monitoring also extends along the supply chain: incidents at key suppliers prompt investor engagement with focal firms. Finally, engagement is associated with higher firm value, stronger ESG performance, and increased cash flows. Together, the findings illuminate the drivers and mechanisms of ESG engagement and underscore …

Growing Up Under Mao And Deng: On Politician Ideology And Corporate Policies, Hao Liang, Rong Wang, Haikun Zhu

Research Collection Lee Kong Chian School Of Business

We provide firm-level evidence on how politicians’ ideologies shape economic outcomes, using a unique setting of ideological discontinuity in China, transitioning from Maoism to Dengism around 1978. We find that ideological exposure during a politician’s early adulthood has a lasting impact on contemporary firm policies in their city. Firms governed by “Maoist mayors” show greater stakeholder spending, lower pay inequality, and less internationalization compared with those governed by “Dengist mayors.” Further evidence suggests that politicians’ ideologies influence corporate behaviors through nonpolicy channels, and these results cannot be fully explained by selection bias, endogenous matching, or the age of the mayor.

Fungicidal Management Of Spring Dead Spot Using Improved Modeling And Application Strategies, Michael Vincent Battaglia

Graduate Theses and Dissertations

Spring dead spot (SDS) is a destructive disease of bermudagrass (Cynodon Rich. spp.) in parts of the world that experience winter dormancy. Fungicides are often necessary to properly manage SDS, and significant research has been conducted to improve fungicidal effectiveness. Several studies were conducted with the objectives of improving fungicide application timing, method of fungicide application, and long-term fungicidal efficiency. In the fungicide application study, a cooling degree-day (CDD) model based on soil temperatures was developed. The CDD model showed that isofetamid was highly effective against SDS during a wide application window in autumn, while tebuconazole was inconsistently effective and …

Deepening Our Understanding Of Resilience: How Evaluation Can Contribute, Michael Quinn Patton

The Foundation Review

Resilience is the capacity to experience a significant shock and adapt as needed to survive and move forward. The current age is one of constant system shocks economically, environmentally, and politically. Resilience becomes essential for navigating these and other risks.

Individuals, organizations, communities, and ecosystems manifest different degrees and types of resilience requiring appropriately matched evaluation responses. In considering new directions for philanthropic evaluation, this article offers for the first time an overarching framework of four different responses to system shocks and disruptions. This leads to four different evaluation criteria: continuity, adaptation, innovation, and capitulation.

In addition to the long-term …

National Hero And Water Deity: The Worship Of Triệu Việt Vương In The Red River Delta, Vietnam, Huong Thi Nguyen

Graduate Theses and Dissertations

In my dissertation, the theory of collective memory will be deployed to address many questions regarding retaining, recovering, and re-creating the worship of King Triệu Việt Vương. He was a legendary, historical king of Vietnam who supposedly lived in the 6th century. His achievements were connected to the people living in the Red River Delta in their fight against the Liang invasion. The villagers who lived near or in this area also honored him for his spiritual power. They built a small temple/ shrine right by the riverbank to worship this King. The Vietnamese dynasties, Ly (in the 11th century), …

World On Fire: The Hunger Games And The Rhetoric Of Revolution, Rachel Olivares

Electronic Theses and Dissertations

In the decade between 2010 and 2020, more people participated in mass protests than at any other point in human history. From the Arab Spring to Occupy Wall Street and Hong Kong’s “umbrella movement,” street demonstrations exploded on a global scale. This period of global unrest coincided with another explosion: the dystopian young adult series The Hunger Games surged in popularity, quickly becoming a cultural phenomenon. Following the release of the book series and its subsequent film adaptations, The Hunger Games became a global symbol of grassroots resistance as social and political movements adopted the language and symbols of its …

The Influence Of Tert-Butylhydroquinone (Tbhq) On Acod1/Irg1-Driven Inflammatory Pathways, Alyssa M. Whisel

All Dissertations

The demand for processed foods has led to increased use of synthetic phenolic antioxidants (SPAs), notably tert-butylhydroquinone (TBHQ), to inhibit lipid oxidation and prolong shelf life. While TBHQ is deemed safe at regulated levels, concerns arise from studies indicating potential adverse effects such as oxidative stress, genotoxicity, and impaired immune function. To investigate TBHQ's immunomodulatory effects, RAW 264.7 murine macrophages were pre-treated with TBHQ and subsequently stimulated with lipopolysaccharide (LPS) or polyinosinic-polycytidylic acid (poly I:C, PIC) to simulate bacterial or viral challenges. Results demonstrated that TBHQ at high non-cytotoxic doses reduced nitric oxide and IL-10 production while promoting phagocytosis and …

The Ai Contributor: A New Thought Partner In Systems Change, Jewlya Lynn, Rachel Reichenbach

The Foundation Review

Many foundations are making long-term commitments to advancing systemic change, continually adapting and refining their approaches along the way. An emerging and often underutilized tool in their systems change toolkit is generative artificial intelligence (AI).

AI is enhancing practices across philanthropy, often focused on increasing efficiencies and scaling or streamlining human tasks. What if we instead focus on what AI can do that is distinctly different from what a human can offer? In the world of systemic change, we continue to struggle with the complexity and intractability of systems and finding moments when systems can be shifted. AI can be …

Base Building Evaluation: Three Opportunities To Improve Its Use And Relevance, Katie Fox, Margaret A. Post

The Foundation Review

The concept of base building comes from the traditions of electoral and labor organizing, where organizers focus on drawing leadership from a specific constituency or geography. Base building is foundational to organizing efforts. It involves the recruitment, training, and leadership development of people who are often most directly impacted by the issues and causes that organizing focuses on.

In recent years, base building has seen increased interest and investment from the philanthropic sector as funders recognize base building as critical to community-led change. As funders expand their investment in base building, they increasingly seek information and data about base building …

Philanthropy As Risk Capital: Shaping Trust And Learning At The Speed Of Ai, Nina Sabarre, Clara Bennett, Laura Chavez-Varela

The Foundation Review

As artificial intelligence rapidly reshapes society, philanthropy is increasingly called to act as "risk capital" for the public good. But risk alone is not enough. Without rigorous, field-wide learning, philanthropy's bold bets may remain isolated and short-sighted, failing to catalyze the systemic change this moment demands.

This article draws on three sources of learning at Omidyar Network—an evaluation of The Tech We Want initiative, external strategy consultations with 29 stakeholders, and early learnings from a generative AI portfolio—to identify how philanthropy can uniquely "de-risk" AI innovation for collective benefit.

Through trust-based partnerships, ecosystem infrastructure support, and narrative change, these learning …

Purifying Circular Rna Therapeutics, Karen Guillen-Cuevas

All Dissertations

Circular RNA (circRNA) has emerged as a promising therapeutic modality due to its enhanced stability and resistance to exonuclease degradation compared with linear mRNA. However, its stability and functionality depend strongly on achieving high purity, and current methods such as size-exclusion chromatography suffer from peak overlap, low yields, and poor scalability. This dissertation addresses these limitations by developing ultrafiltration-based strategies to purify circRNA directly from in vitro transcription (IVT) and self-splicing (circularization) reactions. First, the feasibility of ultrafiltration was demonstrated using polyethersulfone membranes, where sieving coefficients and critical flux values of circRNA, precursor RNA, and nicked RNA were measured to …
