Group Operations For Concurrent Binary Search Trees, Theodora R. Cooper

Dissertations and Theses

A group operation performs multiple independent instances of the same operation on a data structure. For example, a group operation might look up 10 different keys in a binary search tree, returning 10 results. Chen et al introduced group prefetching, an optimization for group operations on linked data structures that improves throughput by overlapping memory access latencies for independent traversals. Constructing code that maximizes this throughput benefit by fully leveraging the instruction- and memory-level parallelism available on modern hardware is challenging because of overhead, interactions with the cache hierarchy, and other factors.

To address these challenges, we present two new …

The Shrinking Caspian Sea: Eco-Hydrological Responses To Human And Climate Pressures, Jesse Duku, Mohammad J. Tourian, Marzi Azarderakhsh, Rovshan Abbasov, Ali Mehran, Ali Torabi Haghighi, Stefanos Xenarios, Azara Boschee, Salih Babagiray, Mojtaba Sadegh, Nima Shokri, Ali Nazemi, Alireza Farahmand, Samaneh Ashraf, Temur Khujanazarov, Elmira Hassanzadeh, Dalal Najib, Daniel Placht, Shamshagul Mashtayeva, For Full Author List, See Comments Below

Faculty Research, Scholarly, and Creative Activity

The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …

Ambivalence, Foremourning, And Displacement In The German Translation Of Marie Bonaparte's Topsy, Kooper Wilson

University Honors Theses

This paper offers a reading of Sigmund Freud’s German translation of Marie Bonaparte’s book, Topsy: The Golden-Haired Chow, in which the author attempts to both delay the death of her dog and mourn it in advance through what I call foremourning. I argue that the manifest subject matter of Topsy should not be interpreted away as a projection of merely human concerns, but rather that close attention to Freud’s translation introduces themes from his analytic experience which engender an appreciation of Topsy’s atopia (intractability). I draw from recent psychoanalytic theory, literary criticism, and deconstruction, especially Jacques Derrida’s seminars …

Growth In Early Infancy Drives Optimal Brain Functional Connectivity Which Predicts Cognitive Flexibility In Later Childhood, Chiara Bulgarelli, Anna Blasi, Samantha Mccann, Bosiljka Milosavljevic, Giulia Ghillia, Ebrima Mbye, Ebou Touray, Tijan Fadera, Lena Acolatse, Sophie E Moore, Sarah Lloyd-Fox, Clare E Elwell, Adam T Eggebrecht, Bright Study Team

2020-Current year OA Pubs

Functional brain network organisation, measured by functional connectivity (FC), reflects key neurodevelopmental processes for healthy development. Early exposure to adversity, for example undernutrition, affects neurodevelopment, observable via disrupted FC, and leads to poorer outcomes from preschool age onwards. We assessed longitudinally the impact of early growth trajectories on developmental FC in a rural Gambian population from age 5-24 months. To investigate how these early trajectories relate to later childhood outcomes, we assessed cognitive flexibility at 3-5 years. We observed that early physical growth before the fifth month of life drove optimal developmental trajectories of FC that in turn predicted cognitive …

Empirical Analysis And Optimization Of Impingement Cooling-Jet-Geometry For Austempering Hot-Rolled Steel Using Computational Fluid Dynamics, Azubuike Michael Nwankwo, Thomas Okechukwu Onah, Bertrand Nduka Nwankwojike

Engineering and Technology Journal

This investigation evaluates stationary impingement cooling of two bio-based fluids on a rectangular steel plate (230 × 120 × 12 mm) using jet diameters of 10 mm and 40 mm across impingement gaps of 115–155 mm. The study addresses the critical need for sustainable cooling media in metallurgical processes while advancing fundamental understanding of bio-fluid jet impingement heat transfer through integrated experimental-computational methodology. ANSYS-based numerical simulations and parametric optimization assessed how jet diameter and impingement gap influence convective heat transfer coefficients and governing dimensionless parameters. Temperature–time data were analysed using lumped thermal mass methods, generating empirical correlations from Reynolds, Nusselt, …

Managing Ai Bot Access To Open Scholarly Infrastructures, Petr Knoth

FORCE 2026

The rapid rise of generative AI has created unprecedented demand for large, high-quality research corpora. Open access repositories and other open scholarly infrastructures have therefore become primary sources for AI bots, because they host research that is not universally reliable, but remains far more evidence-based than most web content. This is both an opportunity and a strain: repositories are now more valuable than ever, but machine traffic brings sustainability, capacity and policy challenges. Repositories may be able to scale, but who should fund that scaling, and under what conditions?

The core dilemma is how to curb abusive high-load bot activity …

[Birds-Of-A-Feather] Understanding And Handling Software Plagiarism In The Age Of Generative Ai, Daniel S. Katz, Scott C. Edmunds

FORCE 2026

Computing and software have supported research since their inception, and continue to play a significant role in knowledge production. However, the means of communicating research methods and results were developed long before computing existed, and the research community lacks best practices for documenting computational research elements transparently, reproducibly, and reusably.
Publishers are now more accepting of the inclusion of software (typically, source code) associated with submitted manuscripts, and many want to support processes to vouch for the integrity of software just as they do for other content, such as ensuring that ethical and legal concerns such as authorship, plagiarism, copyrights …

Research Integrity Without Borders: How Getftr Extends Trust Across The Scholarly Ecosystem, Joris Van Rossum

FORCE 2026

As research discovery increasingly happens beyond publisher platforms (through aggregators, institutional repositories, AI tools, and citation networks) maintaining trust in the integrity of the scholarly record becomes ever more complex. Visibility is not enough; researchers need confidence that what they find, read, and cite is current, authoritative, and trustworthy.

GetFTR (Get Full Text Research) addresses this challenge by embedding integrity and transparency signals, including retractions, errata, updates, and license information, directly into the researcher’s discovery experience. Through its cross-publisher API and integrations with major discovery tools, GetFTR ensures that researchers are always connected to the version of record and alerted …

The $K$-Total Bondage Number Of A Graph, Jean-Pierre Appel, Gabrielle Fischberg, Kyle Kelley, Nathan B. Shank, Eliel Sosis

Theory & Applications of Graphs

Let \(G=(V,E)\) be a connected, finite undirected graph. A set \(S \subseteq V\) is said to be a total dominating set of \(G\) if every vertex in \(V\) is adjacent to some vertex in \(S\). The total domination number, \(\gamma_{t}(G)\), is the minimum cardinality of a total dominating set in \(G\). We define the \(k\)-total bondage of $G$ to be the minimum number of edges to remove from \(G\) so that the resulting graph has a total domination number at least \(k\) more than \(\gamma_{t}(G)\). In this work we establish general properties of \(k\)-total bondage and find exact values for …

Enhancing Digital Literacy Programmes For Advanced Search Skills Of Adult Public Library Patrons, Santel Smit Ms., Nikiwe G. Momoti Dr

Urban Library Journal

Digital literacy enables individuals to confidently engage with electronic devices and digital resources. While many adults use these tools to search for information, some still lack the essential skills to do so effectively. This pragmatic paper investigates the basic digital literacy skills of adult patrons at Adriaanse Public Library in Cape Town. Framed by SCONUL Seven Pillars of Information Literacy through a Digital Literacy “lens”, we employed a sequential mixed-methods approach, combining quantitative pre- and post-tests with qualitative interviews among 30 purposively selected participants. Quantitative data was analyzed statistically while thematic analysis was used for qualitative data. The findings revealed …

Resource Utilisation And Quality Of Education In Secondary Schools In Lagos State, Nigeria, Jacob A. Adeyanju

International Journal for Research in Education

The need for the education sector to deliver on its goals has always been a major expectation of all stakeholders in the system. For this expectation to be met, the major resources in the school system must be combined in a reasonable proportion. On this premise, this study investigated the relationship between resource utilisation and quality of education in Lagos State. The study was conducted using descriptive survey research design with a population of 664 public secondary schools in Lagos State, Nigeria. These schools had a total population of 23,793 teachers. A self-developed instrument titled “Education Resource Utilisation and Quality …

The Effect Of Practice Test Timing On Students’ Test Anxiety And Exam Performance, Alanood M. Al-Thani, Mutasem M. Akour

International Journal for Research in Education

This quasi-experimental study employed a switched replication design to investigate the effect of practice test timing on test anxiety and exam performance among 154 female undergraduate students. Participant groups received online practice tests either early in the semester (before the midterm) or later (before the final exam). Results indicated a significant effect of practice test timing on test anxiety. While both groups exhibited a significant decrease in test anxiety over time, this reduction was more pronounced for the group that took the practice test early. Furthermore, a significant negative correlation was found between final exam performance and test anxiety. These …

Cogstack: Persistent Ai Cognition And Multi-Vendor Cognitive Stacking, Niels S. Goldstein

Defensive Publications Series

CogStack is a two-layer architecture for autonomous AI agent systems. The first layer, the persistent cognition substrate, externalizes the context produced by interactive AI sessions, compresses it into a durable memory store, and rehydrates it into subsequent stateless API calls, enabling agents to reason continuously across sessions and execution environments. The second layer, multi-vendor cognitive stacking, orchestrates agents drawn from different model providers and families so the composite system exhibits emergent properties that no single constituent produces alone — specifically, decorrelated diversity in which each agent's failure modes do not coincide with the others'. CogStack is designed as the orchestration …

Concise And Informative Article Titled The Influence Of Islamic Modern Life On People's Visits To Places Of Reflexology, Andrea Angeline Hidayat, Boike Janus Anshory, Oktavianus Nangoy

Nusantara Halal Journal

Reflexology is a treatment that attempts to recover a body that is worn out, uncomfortable, or ill. Numerous health issues are emerging due to the modern lifestyle we presently live. The body could get physically and psychologically exhausted from daily activities, workplace physical activity, and other stressful situations. Muscle stiffness may happen from job responsibilities that are unmoved and lack movement. Activities that require a lot of muscle and body movement increase the risk of injuries to the body, including strains and sprains. Accuracy and focus during working or doing routine duties might be affected by mental tiredness. Modern life …

Heavy Metal Contamination In Red Sea Hamour Fish: Bioaccumulation Patterns, Toxicological Impacts, And Microbial Community Disruption, Haifa O. Aljuhani, Osamah A. Ahmad, Ashwaq R. Almohammadi

The Journal of King Abdulaziz University: Science

Red Sea heavy metal pollution lately poses a serious threat to human health and ecological integrity. The present research review examines the several effects of heavy metal contamination on the economically important Hamour fish (Epinephelus spp.), a major bioindicator species because of its benthic feeding habit and great bioaccumulation potential. Where the industrial activities, hydrocarbon exploration, desalination effluent, and coastal urbanization have produced continuous pollution vectors, promoting bioaccumulation via gill absorption, food intake, and dermal absorption in Hamour tissues. Our work demonstrates complicated toxicological effect comprising oxidative stress, hematological malfunction, immunosuppression, neurotoxicity, reproductive impairment, and genotoxic damage. Consequently, heavy …

Individualism And Momentum Revisited: Evidence On The Persistence Of Cultural Drivers In Stock Market Returns, Hayley S. Sciubba

Economics Undergraduate Senior Theses

This paper reexamines the relationship between cultural differences and momentum strategy returns over the period March 2007 through March 2026, building on the Chui, Titman and Wei (2010) finding that higher individualism is associated with greater trading volume, volatility, and momentum profits. Cross-country cultural differences are measured using an individualism index developed by Minkov et al. (2017), which is related to overconfidence and self-attribution bias. Using monthly stock price data, I construct cleaned monthly returns and sort stocks into six-month momentum portfolios. Although many of the 41 countries common to the original and current samples have experienced changes in their …

Selective Contagion: Sovereign Credit Integration And Heterogeneous Shock Transmission In Emerging Equity And Derivative Markets, Fabiana Araujo Rincón

Economics Undergraduate Senior Theses

Contagion in Latin America is real but selective: the direction of spillover depends on whether a country is integrated more strongly into global or regional markets. Using a stacked event study across 90 manually identified shocks from 2001 to 2026, I estimate regional contagion and its determinants across credit, currency, equity, and derivative markets. Contagion travels through sovereign credit, not currency, and through economic, not political, shocks. Political shocks, despite their larger domestic impact, stay locally contained. The direction of spillover turns on shock origin: shocks from large, globally integrated economies depress their peers, while shocks from smaller, regionally focused …

Implied Variance Asymmetry As A Predictor Of Stock Returns Around Quarterly Earnings Dates, Matthew J. Sebastian

Economics Undergraduate Senior Theses

This paper investigates whether option-implied variance asymmetry, defined as the difference between upside and downside risk-neutral semivariances measured shortly before scheduled quarterly earnings announcements pre- dicts the cumulative abnormal return realized over the announcement win- dow. We find implied variance asymmetry positively and significantly pre- dicts announcement-window returns in S&P 500 companies: the high-minus- low quintile sort portfolio earns 45 basis points over a five-day window with a Fama-French four-factor alpha of 60 basis points, both statistically signif- icant. The results suggest a temporary break in market efficiency and are consistent with an informed-trading interpretation in which earnings specific information …

Flip It And Reverse It: Probing Consistency Of Llm World Knowledge Under Logical Transformations, Rhianna Smith

Computer Science Senior Theses

When assessing the extent to which someone truly understands the topics they discuss, you might ask them a series of questions that examine their knowledge from different angles. As Large Language Models (LLMs) are increasingly integrated into real-world tasks, they are often required to reason through ambiguous and uncertain scenarios that rarely have a single correct answer. In these settings, their usefulness is contingent on more than accuracy alone. Rather, it depends on the strength of the reasoning that underlies their responses. This begs the question: how might we extend these types of tests to LLMs? We formalize this informal …

Unheard Voices: Language And Humanity In Memoirs Of Immigration From Latin America To The United States, Aj Setala

Honors Projects

At the time of writing this project, aggressive Immigration and Customs Enforcement (I.C.E.) raids and mass deportations are being carried out across the U.S. The need to recognize the humanity of those targeted grows with every deportation. In this project, I address the question - What does it mean to be human? - by considering how language impacts the ways in which others affirm or deny the humanity of immigrants. To do this, I examine the role language plays in memoirs of undocumented Latin American immigrants. My analysis is grounded in Gloria Anzaldúa’s borderlands theory and César Miguel R. Vega …

Distribution, Abundance And Habitat Utilization Of Sea Turtles In The Northern Gulf Of Mexico, With An Emphasis On Coastal Mississippi, Theresa Rose Madrigal

ETDs from 2020-2029

The Gulf of Mexico represents important habitat for a variety of sea turtle species. This includes habitats for the various life history stages ranging from the oceanic stage of hatchling and post-hatchling turtles, neritic subadults, to the adult foraging and reproduc-tive stages. In contrast to many areas of the Gulf of Mexico, there has been a limited amount of data reported on sea turtle nesting as well as sea turtle foraging and develop-mental habitat in the north central Gulf of Mexico. This thesis includes two studies which investigate the importance of the coastal areas of Mississippi as sea turtle habitat. …

Bad Mothers In Translation: Early Motherhood In Contemporary Turkish Editions, Merve Sevtap Süren

Journal of Feminist Scholarship

This article examines how three recent Anglophone novels of early motherhood, namely, Szilvia Molnar’s The Nursery (as Süt Lekesi), Rachel Yoder’s Nightbitch (as Gece Kancığı), and Claire Kilroy’s Soldier Sailor (as Asker ile Denizci), circulate in Turkish translation in a context shaped by pronatalist moral economies. Pairing peritextual analysis (covers, back-cover copy, blurbs, and bio notes) with close readings of selected key scenes of postpartum crisis, feral transformation, and toddler-year burnout, I show how Turkish editions both render and manage maternal negativity: translation choices modulate voice, affect, and register, while peritexts frame these mothers for local readability …

Fixing Furiosa’S Feminism: Gender And Genre In Feminist Criticism Of Mad Max: Fury Road (2015), Maik Stanitzke

Journal of Feminist Scholarship

This article examines how the figure—or genre—of “woman” is produced and contested within the traditionally masculine action film through the critical reception of Mad Max: Fury Road. While debates over whether the film is feminist appear to center on representation, they reveal a deeper investment in stabilizing “woman” as a coherent political object. Drawing on feminist film theory, I argue that if the film seems nostalgic for a regenerative birth mother at a moment when sexual difference is reconfigured by queer and trans studies, feminist criticism’s investment in what Robyn Wiegman calls “the world-making stakes of identity knowledge” (2012, …
