Crustose Coralline Algae Accretion In A Kelp Forest Ecosystem In Southern New England, Usa, Ruimeng Liu

Theses, Dissertations and Culminating Projects

Temperate reef ecosystems are experiencing rapid canopy loss of kelp and the proliferation of algal turf. However, the consequences of these changes for crustose coralline algae (CCA)— a key but often overlooked benthic calcifier—are poorly understood. Here, I study CCA recruitment patterns in southern New England, USA, using standardized settlement tiles at two field sites over 12 months (September 2023 – August 2024). I measure CCA accretion rates and the associated biological and environmental correlates of CCA recruitment. At the two sites, CCA accretion rates ranged from 0.0259 to 1.215 mg CaCO3 cm⁻² yr⁻¹, with an average of 0.441 mg …

Theses, Dissertations and Culminating Projects

This study examines a group of five queer teachers of varied ages and genders who discussed their lived experiences navigating the heteronormativity of public school structures in conjunction with their work using queer pedagogy to support students. It answers the research question: How does the lived personal history of queer educators influence how, when, and in what ways they take up queer pedagogy? Employing a life history interview methodology, along with queer theory as a theoretical framework, this study explores intersections of the participants’ life history and their engagement in queer pedagogy to examine why and how they are driven …

Comparative Expression Of Cgmp-Dependent Protein Kinase G (Pkg) From Plasmodium And Toxoplasma, Tsopmo Asaah

Theses, Dissertations and Culminating Projects

Malaria and Toxoplasmosis are life threatening diseases to humans. The search for a cure and control of these diseases is still one of the major challenges of scientists worldwide. In this research we focused on two Malaria species; Plasmodium bergei² (Pb) and Plasmodium falciparum¹ (Pf) and also on Toxoplasma gondii. Part of the life cycle of these organisms is regulated by the enzyme cyclic GMP-dependent protein kinase G (PKG)⁴. This is our drug target in this research. We believe that inhibiting this enzyme will be a great step in fighting these diseases. In this research, we devised a comparative study …

A Multi-Proxy Approach For Understanding The Chicxulub Asteroid Impact (Cretaceous / Paleogene Boundary) And Its Aftermath, Hermann D. BermúDez

Theses, Dissertations and Culminating Projects

The Chicxulub asteroid impact in what is now the Yucatan Peninsula, Mexican Caribbean, coincides with the Cretaceous/Paleogene boundary (K/Pg boundary ~66Ma) and marked the extinction of three-quarters of the species, including the iconic non-avian dinosaurs. The collision created a massive crater, releasing enormous amounts of energy and expelling millions of tons of molten and vaporized materials into the atmosphere. Chicxulub is an ideal case study for massive impact events since it is the only recognized asteroid impact on Earth's history that preserved a globally traceable ejecta layer representing a precise time-stratigraphic marker. Although numerous studies have examined the consequences of …

Simulation Of Photochemical Effects On Air Quality, Grace Li

Chemical Engineering Undergraduate Honors Theses

Nitrogen dioxide (NO₂) and ozone (O₃) are both EPA criteria air pollutants in the troposphere, largely generated by combustion and therefore present in significant concentrations in urban areas. Sunlight facilitates chemical reactions between pollutants and ambient air. Aerosols modulate the amount of available energy required to drive such photochemical reactions, ultimately impacting air quality. Simulating photolysis rates with FastJX software is a resource-efficient strategy to study how these aerosols can affect air quality.

Investigating The Influence Of Experimental Parameters On The Formation Of Gold Nanoparticles: A Green Synthesis And Design Of Experiments Approach, Isaac Opeyemi Subuloye

Master's Theses

This thesis examines the green synthesis of gold nanoparticles using catechin, a naturally occurring plant-derived compound, as both a reducing and capping agent. The synthesis process was guided by a structured Design of Experiments (DOE) methodology to ensure systematic investigation and optimization. A two-phase experimental approach was adopted. First, a full factorial screening design was used to evaluate the effects of catechin concentration, NaOH concentration, and pre-reaction time. This was followed by an optimization phase using a face-centered composite design to identify conditions that produce nanoparticles with ideal characteristics. The nanoparticles were analyzed using UV-visible spectroscopy and dynamic light scattering …

Examining The Impact Of A Comprehensive School Physical Activity Program On High School Students' Health And Well-Being, Joshua Robinson

Doctorate in Kinesiology

This dissertation examined the impact of a Comprehensive School Physical Activity Program (CSPAP) on high school students’ perceived physical, mental, emotional, and academic wellness. Using a mixed-methods design, data were collected from 701 pre-surveys, 175 post-surveys, 603 post-intervention impact surveys, and two student focus group interviews. The yearlong CSPAP intervention was implemented using the CDC’s seven-step framework at a public charter high school during the 2024–2025 academic year. Quantitative results revealed statistically significant improvements in students’ self-reported physical health, mental wellness, emotional resilience, and academic engagement, with mental health and perceived enjoyment of physical activity showing the strongest gains. Perceived …

Hearing From Working Nurses: Incorporating Real-World Knowledge Practices Into The Framework To Better Instruct Tomorrow's Healthcare Professionals, Anne R. Diekema, Elizabeth (Betsy) S. Hopkins, Britt Fagerheim, Brandon Patterson, Nena Schvaneveldt

Faculty Publications

There is a certain duality to the role of librarians in higher education as the job requires preparing students for their current academic work, such as doing research for writing papers, while at the same time preparing students for their future professional information work. Librarians seeking guidance on teaching information literacy more comprehensively are left to study the professional standards of the targeted professional group, and find or carry out research on these practitioners. Synthesizing and translating these findings into instructional approaches while staying true to existing information literacy standards, however, can be challenging. In this chapter we demonstrate how …

What Values Best Distinguish The World's Cultures? The Machine Learning-Based Cultural Values Inventory, Abhishek Sheetal, Shilpa Madan, Rui Ling Lee, Krishna Savani

Research Collection Lee Kong Chian School Of Business

Scientists studying culture typically focus on a small number of theoretical constructs, such as individualism–collectivism, when seeking to explain cultural differences in psychological tendencies and behaviors. However, existing theories of culture could have missed out on important constructs that are useful for explaining cross-cultural differences. We used an abductive approach combining prediction and explanation to uncover important cultural values. In the prediction phase, based on 594 attitudes, values, and beliefs included in the World Values Survey, a neural network could classify respondents’ nationalities with 90% accuracy in out-of-sample data. In the explanation phase, a feature importance analysis identified the values …

Research outputs 2022 to 2026

This study maps the intellectual landscape of research on poverty in Islam using a structured bibliometric approach with Biblioshiny (Bibliometrix) in RStudio. A Scopus search (TITLE-ABS-KEY “poverty” AND “Islam”) conducted on 1 September 2023 identified 279 English-language journal articles published between 1976 and 2023. The corpus spans 227 sources, 646 authors, and 10,262 cited references, with an annual growth rate of about 5%. Performance and science-mapping analyses reveal two “motor themes”—Islamic finance and healthcare/public health—while spiritually anchored constructs (e.g., maqasid, zakat governance, waqf, spiritual poverty) remain peripheral in co-occurrence and thematic maps. Citation patterns indicate higher field-normalized impact when studies …

Research outputs 2022 to 2026

This study explores the influence of perceived similarity on pro-environmental behavior, focusing on plastic reduction. Participants' daily plastic use and reduction were tracked over 30 days via online chat software, with controlled nudges from an agent. Each group included two examinees and one agent. Behavioral data were analyzed to evaluate predictability from various perspectives and its relationship with behavioral change. Results showed significant differences in predictability based on perceived similarity, particularly during the first 10 days. Furthermore, nudges, consumption levels, and behavioral changes significantly affected predictability within the first 20 days. These findings contribute to understanding how perceived similarity can …

Implementation Of Link Workers In Primary Care: Synopsis Of Findings From A Realist Evaluation, Stephanie Tierney, Geoff Wong, Debra Westlake, Amadea Turk, Steven Markham, Jordan Gorenberg, Joanne Reeve, Caroline Mitchell, Kerryn Husk, Sabi Redwood, Tony Meacock, Catherine Pope, Beccy Baird, Kamal R. Mahtani

Peninsula Medical School

Background: Social prescribing link workers formed part of the Additional Roles Reimbursement Scheme introduced into primary care in England from 2019. Link workers assist patients experiencing issues affecting their health and well-being that are 'non-medical' (e.g. lack of social connections, financial difficulties and housing problems). They give patients space to consider these non-medical issues and, when relevant, connect them to support, often within the voluntary-community-social-enterprise sector. We conducted an earlier realist review on the link worker role in primary care. We then carried out a realist evaluation, described in this report, to address the question: When implementing link workers in …

New Insights Into The Beliefs Of Secondary Pre-Service Teachers About Mathematics, Vesife Hatisaru, Olivia Johnston, Julia Collins, Benjamin Rott

Research outputs 2022 to 2026

Teachers’ beliefs about mathematics can shape how they approach teaching, learning, and assessment in mathematics classrooms. This study examined Australian pre-service teachers’ (PSTs’) epistemological beliefs about mathematics. A total of 18 PSTs enrolled in Bachelor of Education and Master of Teaching (secondary mathematics) programs participated in the study by answering prompt questions in an open-ended questionnaire. The participants’ responses were content analyzed by categorizing the views evident in the responses into four pre-defined mathematical orientations: formalism-related, scheme-related, process-related, and application-related. Findings have shown that the dominant beliefs for the participants reflected process- or application- related orientations to mathematics. These findings …

Skilled Migrants' Experiences Of Othering, Alterity And Language Policing, Uma Jogulu, Maggie Mcalinden, Melissa A. Parris, Juliana Mutum

Research outputs 2022 to 2026

The Australian Permanent Migration Program and related settlement services have been critical to Australia's success as a stable, democratic and culturally diverse nation. However, emerging research has revealed that this success may come with a high price for as many as one in four skilled migrants who find themselves employed beneath their level of education, expertise and experience, which we define as underemployment. We designed a study that sought to understand the settlement experiences of 36 Asia-Pacific-skilled migrants working as managers. Incorporating Spivak's concepts of subalternity, othering and alterity as a theoretical framework, our analysis uncovered how migrant identity intersected …

The Moderating Effect Of Dietary Patterns On The Association Of Depression And Anxiety With Cognitive Function, Hilal Salim Said Al Shamsi, Samantha L. Gardener, Hamid R. Sohrabi, Kevin Taddei, Colin L. Masters, Stephanie R. Rainey-Smith, Ralph N. Martins, W. M.A.D.B. Fernando

Research outputs 2022 to 2026

Background and aims: Investigating modifiable risk factors, such as diet, is crucial in understanding their effects on the relationship between Alzheimer's disease (AD)-related cognitive decline and related conditions. This study assesses whether dietary patterns moderate the relationship between symptoms of depression, anxiety, and cognitive function in older adults. Given that biological and psychosocial differences between sexes may influence dietary behaviours, mental health symptoms, and cognitive outcomes, conducting sex-stratified analyses will allow for identification of differential associations. Method: Cross-sectional data from cognitively unimpaired older adults (n = 1174, age ≥60 years) from the Australian Imaging, Biomarkers and Lifestyle (AIBL) study were …

Research outputs 2022 to 2026

Background: Evidence suggests that plant-based diets (PBDs) may be protective against neurodegenerative diseases such as Alzheimer's disease (AD). Objective: This study examined associations between blood-based AD biomarkers in individuals 30–75 years without current or diagnosed cardiovascular disease following different PBDs versus regular meat-eating diets (RMEs). Methods: This secondary analysis of the Plant-based Diets study measured Aβ1–42/Aβ1–40, p-tau181, NFL, and GFAP in 237 plasma samples using SIMOA from individuals following vegan, pesco-vegetarian (PVs), lacto-ovo vegetarian (LOVs), semi-vegetarian (SVs), or RME diets. Multivariable regression adjusted for age and sex. Results: Following adjustments for age and sex, plasma Aβ1–42/Aβ1–40ratio was significantly higher in …

A Flavonoid-Rich Diet Is Associated With A Lower Risk Of Chronic Kidney Disease: A Prospective Cohort Study, William Bell, Alysha S. Thompson, Nicola P. Bondonno, Amy Jennings, Martina Gaggl, Tilman Kühn, Aedín Cassidy

Research outputs 2022 to 2026

Background and aim: Mechanistic data suggests several flavonoids may improve kidney function, but no large-scale prospective cohort study has been conducted. As such, we performed a prospective population-based study on flavonoid intakes, chronic kidney disease (CKD) risk, and all-cause mortality among participants with CKD. Methods: We examined associations between a Flavodiet score (FDS), individual flavonoid-rich foods and subclasses (based on ≥2 24-h dietary assessments) and a) CKD risk among 109,711 adults, and b) all-cause mortality among 3,287 participants with CKD at baseline, aged 40–69 years using multivariable Cox regression analyses. Additionally, we used mediation analysis to examine potential mechanisms of …

Creating A New Climate Transition Politics? Reflections On A Real Deal For Australia, Amanda Tattersall, Katie Moore, Juliet Bennett, Christine Evans, Louise C. Johnson, Naomi Joy Godden, Dibya Shree Chhetry, Elise Ganley, Sally Fisher, Jaclyn Mccosker, Jade Wright, Liz Bonner, Helen Long, Noreen Nicholson

Research outputs 2022 to 2026

Economic responses to climate change, such as just transitions and the Green New Deal (GND), have helped shift climate policy debate to focus on the economic dimensions of climate change. Yet these approaches have also been limited; they have not always delivered, they have left some groups behind and at times have polarised affected constituencies. This article argues that a key reason for this is that these agendas have primarily involved imposing solutions on communities without activating people's participation in the perpetual cocreation of new social, political and economic solutions. Here, community and academic researchers reflect on the first five …

Endogenous Analgesia, Assessed Via Conditioned Pain Modulation, Is Not Different In People With Hip Osteoarthritis Compared To Controls: A Cross-Sectional Study, Myles C. Murphy, Molly Coventry, Ebonie K. Rio, Paola T. Chivers, Benedict Wand, Gordon Waddington, Andrea B. Mosler

Research outputs 2022 to 2026

Background: In people with knee osteoarthritis, measures of pain sensitivity have been demonstrated to relate to both pain severity and treatment outcomes, dependent on the type of pain sensitivity being tested. Objective: Quantify if differences in the pressure pain thresholds (PPT) or conditioned pain modulation (CPM) effect exist between people with hip osteoarthritis and age-matched controls without hip osteoarthritis. Methods: We performed a cross-sectional study across two geographic locations. PPTs at a local (hip) and remote (elbow) site were collected via a manual algometer. CPM was quantified using PPTs immediately prior to, and during ice water immersion of the hand …

Research outputs 2022 to 2026

This review summarizes recent studies on MXenes and their composites regarding energy storage and nanofluidic devices. MXenes are a new family of two-dimensional transition metal carbides and nitrides that have gained much attention in recent times due to their excellent physicochemical properties, such as its exceptionally high electrical conductivity, even more than that of metals, thermal stability, hydrophilicity, high energy and power densities, tunable structures, and large surface area along with abundant electrocatalytically active sites. These features, along with larger interlayer gaps compared with graphene, point to the emergence of MXenes as energy storage alternatives. Synthesis, properties, and applications of …

Ocular Changes As Potential Biomarkers For Early Diagnosis Of Alzheimer's Disease, Purna Chandra Poudel, Shaun M. Frost, Shaun Eslick, Hamid R. Sohrabi, Kevin Taddei, Eugene Hone, Ralph N. Martins

Research outputs 2022 to 2026

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing, such as cerebrospinal fluid analysis and neuroimaging, have limited the early detection and intervention of the disease. Therefore, researchers have explored cheaper and less invasive options, such as ocular imaging. This review discusses the close relationship between the eye and the central nervous system and ocular changes as a potential non-invasive AD biomarker. Ocular changes …

Successful Treatment Of Aspergilloma With Antifungal Alone: A Case Of Conservative Management, Ad Rian Chong, Khai Lip Ng, Nai Chien Huan, Nur Husna Mohd Aminudin, Raja Nor Adilla Raja Rahaizat, Kasuma Mohamed Nordin

Research outputs 2022 to 2026

Pulmonary aspergilloma can cause life-threatening haemoptysis. Surgical resection and/or bronchial artery embolization (BAE) are established treatment modalities, but both can be risky in frail patients with comorbidities. Spontaneous regression of aspergilloma with antifungal agents alone is rare. We report an elderly gentleman with a background history of treated pulmonary tuberculosis, who presented with haemoptysis due to a large left upper lobe aspergilloma. He declined surgery and BAE due to perceived risks. Oral voriconazole and later isavuconazole were prescribed, which led to clinical improvement and significant reduction in the size of the aspergilloma over 6 months. Antifungal agents might be a …

Would Order-By-Order Auctions Be Competitive?, Thomas Ernst, Chester Spatt, Jian Sun

Research Collection Lee Kong Chian School Of Business

We model two methods of executing segregated retail orders: brokers’ routing,whereby brokers allocate orders using the market maker’s overall performance, andorder-by-order auctions, where market makers bid on individual orders, a recent U.S.Securities and Exchange Commission proposal. Order-by-order auctions improve al-locative efficiency, but face a winner’s curse reducing retail investor welfare, partic-ularly when liquidity is limited. Additional market participants competing for retailorders fail to improve total efficiency and investor welfare when entrants possess in-formation superior to incumbent wholesalers. Our results hold when new entrants are less informed or the information structure differs. We also examine the cross-subsidization of brokers’ routing.

Not All Political Ties Are The Same: Firms' Ties To The Government And Pollution, Wen Helena Li, Ilya R. P. Cuypers, Gokhan Ertug, Hari Bapuji, Wei Liu

Research Collection Lee Kong Chian School Of Business

Complementing research on the implications of political ties for firms’ strategic decisions and financial performance, recent studies are increasingly focusing on the environmental consequences of firms’ political connections. We contribute to this stream of work by integrating insights from the literature on political ties and the multifaceted nature of governments to explore how the level of government influences the pollution implications of firms’ political ties. Specifically, we theorize and demonstrate that, in China, firms' achieved political ties with high levels of the government reduce pollution, while such ties with low levels of the government increase it. Furthermore, we examine how …
