Investigation Of Retention And Dehydration Of Preformed Particle Gel For Conformance Control In Fractured Carbonates, Abdulaziz A. Almakimi, Abdullah O. Almansour, Junchen Liu, Baojun Bai, Ibnelwaleed A. Hussein

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Preformed particle gel (PPG) treatment has proved to be among the most effective methods to reduce excessive water production in fractured reservoirs. The blocking ability of PPGs to fractures or fracture-like features is highly dependent on injected gel properties and volume. Gel dehydration during extrusion through fracture is common and has a considerable effect on gel properties, transport, and plugging efficiency. As the gel particles propagate through the fracture, continuous dehydration is often associated and causes the gel to concentrate and require high-pressure gradients to move. Dehydration might be desirable to a certain limit because it can help to form …

On Sgx’S Voyage To Corporate Sustainability: Exploring Emerging Topics In Multi-Industry Corpora, Xinwen Ni, Min Bin Lin, Simon J.D. Schillebeeckx, Wolfgang Karl Hardle

Research Collection Lee Kong Chian School Of Business

Topic modeling and LDA (Latent Dirichlet Allocation) have proven valuable in various fields as an innovative approach to studying areas of interest and identifying topics in a dynamic content. The underlying assumption is that techniques like LDA can swiftly capture emerging topics in textual documents compared to other categorization tools. These unsupervised approaches have been used to identify new industries and technological domains. However, our study on the nascent topic of “sustainability” within the corpora of SGX-listed companies highlights clear limitations in employing techniques like LDA on sparse data. The dynamic LDA approach, also called DTM (Dynamic Topic Modelling),based on …

Stress Reactivity And Sociocultural Learning: More Stress-Reactive Individuals Are Quicker At Learning Sociocultural Norms From Experiential Feedback, Shilpa Madan, Krishna Savani, Pranjal H. Mehta, Desiree Y. Phua, Ying-Yi Hong, Michael W. Morris

Research Collection Lee Kong Chian School Of Business

When interacting with others in unfamiliar sociocultural settings, people need to learn the norms guiding appropriate behavior. The present research investigates an individual difference that helps this kind of learning: stress reactivity. Interactions in an unfamiliar sociocultural setting are stressful, particularly when the actor fails to follow its rules. Although stress is typically considered a liability, more stress-reactive individuals may be more motivated to improve, and, thus, quicker to learn these rules. Consistent with this idea, a pilot study found that people genetically inclined to stress reactivity, as computed by a genetic profile score across 59 single nucleotide polymorphisms on …

In this study, MPs have been determined in three physiological fluids: urine, sputum and bronchoalveolar fluid (BALF); from 30 adult patients in Iran with respiratory conditions. A total of nine small (20–100 μm) and mainly green and red fibres of polyethylene, polypropylene and polystyrene construction were detected in urine samples of eight participants. By contrast, 358 MPs that were dominated by small, white and transparent fibres, but also included larger (100–500 μm) fibres and fragments and spherules of various sizes, were detected in sputum …

Capacity Investment In The Presence Of Correlated Demand And Production Resource Uncertainties And Its Implications For Financial Hedging, Onur Boyabatli, Guiyun Feng

Research Collection Lee Kong Chian School Of Business

In manufacturing firms, besides demand uncertainty, capacity investment decisions may also be subject to uncertainty in the availability of a production resource (e.g., budget or commodity component) which may become constraining for manufacturing. When the production resource uncertainty is tied to a financial index (e.g., asset or commodity price), the firm can enter into financial hedging contracts at the time of capacity investment to engineer this uncertainty. Our paper characterizes the optimal capacity investment and hedging decisions and examines how production resource uncertainty impacts the firm’s decisions, profitability, and the value of hedging. We identify three key drivers of these …

The Correlation Between Depression And Gendered Racism Among Black Women, Charmagne M. King

Dissertations

Black women face unique challenges related to intersecting racial and gender-based discrimination, often referred to as gendered racism. Previous research has indicated this form of oppression may significantly affect mental health, particularly depression. However, few studies have examined how gendered racism interacts with racial identity and demographic factors (e.g., age, marital status, geographical location) to predict depressive symptoms. Using a sample of 164 self-identified Black women, this study investigated the correlational relationship between gendered racism and depression among Black women and examined how gendered racism, racial identity, and key covariates (age, marital status, and geographical location) predict depressive symptomatology. The …

Effective And Empowering Psychotherapy For Black Women: A Culturally Adapted Proposed Model, Kaylla A. Jackson

Dissertations

Black women in the United States are a minoritized group that has experienced oppression and suffering explicitly targeting their intersectional and minority identities. The intensity and frequency of stressors result in a negative impact on Black women that prompts a need to cope. Rather than relying on professional mental health care, many Black women rely on their religious and spiritual communities and other cultural and historical methods to cope with stressors. As a field and profession, clinical psychology has been overwhelmingly dominated by White individuals. The profession has a rich history of developing and perpetuating oppressive systems that have ignored …

Understanding The Afghan Newcomer Experience From The Perspectives Of Teachers And Students, Elisabeth C. Trost

Dissertations

Newcomer English learners (ELs) often arrive in the United States having fled persecution, economic or political oppression, war, or natural disasters in their country of origin. They are new to the English language, new to the American school system, at times well into their educational journey, and sometimes have missed out on significant amounts of formal schooling. Many also carry trauma from the circumstances that forced them to leave their homes. Most schools are not fully equipped to welcome these students and their families into the learning community, nor are they prepared to address the unique challenges newcomer ELs face. …

The Impact Of Restorative Practices Intervention On School Culture, Lisa Peloquin

Dissertations

The American educational system, historically designed to empower a few while training the majority to be docile workers, is increasingly being called upon to promote greater equity. While some reform efforts promote highly restrictive behavioral policies to boost student achievement, these approaches often serve to recreate the oppressive school systems they seek to reform. Restorative practices, an alternative approach to school reform, emphasizes creating a culture of strong relationships, where children learn the academic and social emotional skills they need to be successful. This paper presents a case study of one urban, public school’s implementation of restorative practices, examining its …

A Phenomenological Qualitative Study Of Sense Of Community In An Inner-City Parochial School: Expanding The Seats At The Table., Mary Andree Darnall

Lower levels of perceived administrative support were significantly correlated with higher burnout and greater intent to leave the profession. Qualitative thematic analysis identified key stressors, including inconsistent administrative communication, escalating student …

Intersecting Inequities: Latinx Access To Mental Health Services, Melissa Thorson

Dissertations

This study examined barriers to mental health service utilization among Latinx populations using data from the 2022 National Survey on Drug Use and Health (NSDUH). Through the theoretical frameworks of Minority Stress Theory and Toxic Stress Theory, the study investigated the relationships between age, language proficiency, socioeconomic status, and mental health service access among different Latinx subgroups. Statistical analyses included chi-square tests, multiple regression, and mediation analyses on a sample of Latinx adults (N = 9,852). Results indicated associations between age and English proficiency (χ² = 145.23, p < .001, Cramer's V = 0.38), with 45% of adults aged 50 and older reporting limited English proficiency. Socioeconomic analysis revealed that 32% of older Latinx adults reported family incomes below $20,000, with insurance status partially mediating the relationship between income and service utilization (indirect effect = 0.15, 95% CI [0.08, 0.23]). differences in utilization rates emerged among Latinx subgroups (F(6, 1243) = 8.76, p < .001, η² = 0.12), with Mexican-origin individuals showing higher utilization (10%) compared to Puerto Rican individuals (2-3%). Age and socioeconomic status demonstrated interaction effects (β = 0.18, p < .01), while language proficiency moderated the relationship between age and service utilization (β = 0.24, p < .001). These findings suggest that barriers to mental health service utilization among Latinx populations are complex and interconnected, requiring multilevel interventions that address linguistic, cultural, and socioeconomic factors simultaneously. Implications for healthcare policy and service delivery are discussed, emphasizing the need for culturally responsive and linguistically appropriate mental health services.

Land Access As Liberation: A Qualitative Study On Faith, Food, And Farming Of Urban And Rural Black Land Stewards In The United States, Dominique Edwards

Dissertations

Since 1920, Black farmers in the United States have held less than 2% of the nation's farmland, a direct result of race-based discriminatory policies embedded within federal, state, local, and county-level institutions (Daniel, 2013). Structural barriers—ranging from exclusionary lending practices by the U.S. Department of Agriculture (USDA) to the systematic dispossession of land through legal loopholes, heirs’ property laws, and violent racial terror—have contributed to this staggering decline in Black land ownership (Gilbert et al., 2002). The erosion of Black agrarian landholdings intensified in the latter half of the 20th century, as government programs, civil rights legislation, and technological advancements, …
