Rode: Linear Rectified Mixture Of Diverse Experts For Food Large Multi-Modal Models, Pengkun Jiao, Xinlan Wu, Bin Zhu, Jingjing Chen, Chong-Wah Ngo, Yu-Gang

Research Collection School Of Computing and Information Systems

Large Multi-modal Models (LMMs) have significantly advanced a variety of vision-language tasks. The scalability and availability of high-quality training data play a pivotal role in the success of LMMs. In the realm of food, while comprehensive food datasets such as Recipe1M offer an abundance of ingredient and recipe information, they often fall short of providing ample data for nutritional analysis. The Recipe1M+ dataset, despite offering a subset for nutritional evaluation, is limited in the scale and accuracy of nutrition information. To bridge this gap, we introduce Uni-Food, a unified food dataset that comprises over 100,000 images with various food labels, …

Benchmarking Gaslighting Negation Attacks Against Multimodal Large Language Models, Bin Zhu, Yinxuan Gui, Huiyan Qi, Jingjing Chen, Chong-Wah Ngo, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Multimodal Large Language Models (MLLMs) have exhibited remarkable advancements in integrating different modalities, excelling in complex understanding and generation tasks. Despite their success, MLLMs remain vulnerable to conversational adversarial inputs. In this paper, we systematically study gaslighting negation attacks—a phenomenon where models, despite initially providing correct answers, are persuaded by user-provided negations to reverse their outputs, often fabricating justifications. We conduct extensive evaluations of state-of-the-art MLLMs across diverse benchmarks and observe substantial performance drops when negation is introduced. Notably, we introduce the first benchmark GaslightingBench, specifically designed to evaluate the vulnerability of MLLMs to negation arguments. GaslightingBench consists of multiple-choice …

Sam3-Litetext: An Anatomical Study Of The Sam3 Text Encoder For Efficient Vision-Language Segmentation, Chengxi Zeng, Yuxuan Jiang, Ge Gao, Shuai Wang, Duolikun Danier, Bin Zhu, Stevan Rudinac, David Bull, Fan Zhang

Research Collection School Of Computing and Information Systems

Vision-language segmentation models such as SAM3 enable flexible, prompt-driven visual grounding, but inherit large, general-purpose text encoders originally designed for open-ended language understanding. In practice, segmentation prompts are short, structured, and semantically constrained, leading to substantial over-provisioning in text encoder capacity and persistent computational and memory overhead. In this paper, we perform a large-scale anatomical analysis of text prompting in vision–language segmentation, covering 404,796 real prompts across multiple benchmarks. Our analysis reveals severe redundancy: most context windows are underutilized, vocabulary usage is highly sparse, and text embeddings lie on a low-dimensional manifold despite high-dimensional representations. Motivated by these findings, we …

Frozen Lvlms For Micro-Video Recommendation: A Systematic Study Of Feature Extraction And Fusion, Huatuan Sun, Yunshan Ma, Changguang Wu, Yanxin Zhang, Pengfei Wang, Xiaoyu Du

Research Collection School Of Computing and Information Systems

Frozen Large Video Language Models (LVLMs) are increasingly employed in micro-video recommendation (MVR) due to their strong multimodal understanding. However, existing apporches typically deploy LVLMs as fixed black-box feature extractors without systematically comparing alternative representation strategies. To address this gap, we present the first systematic empirical study on various feature extraction paradigms and integration strategies, along with hierarchical representations from frozen LVLMs for MVR. Extensive experiments on representative LVLMs reveal that hidden states from multiple decoder layers provide richer and more effective representations for MVR. Guided by this insight, we propose the Dual Feature Fusion (DFF) Framework, a lightweight approach …

Co-Designing With Autistic Livestreamers: Care, Constraints, And Trade-Offs In Livestreaming, Terrance Mok, Anthony Tang, Lora Oehlberg

Research Collection School Of Computing and Information Systems

Autistic livestreamers use platforms like Twitch for social connection, self-expression, and community, but these spaces also impose ongoing social and emotional demands. Prior work has documented these experiences, but less is known about what autistic creators themselves envision for the tools and platforms they use. We address this gap through a Research through Design (RtD) co-design study with three autistic Twitch streamers, using speculative artefacts as discussion prompts to explore how participants reasoned about potential livestreaming technologies. Across three co-design activities, we identify three overarching tensions shaping autistic streaming practice: Expression versus Misinterpretation and Harm; Public Participation versus Control and …

History To Future: Evolving Agent With Experience And Thought For Zero-Shot Vision-And-Language Navigation, Guangzhao Dai, Shuo Wang, Zihan Wang, Guo-Sen Xie, Yang Yang, Jinshan Pan, Qianru Sun, Xiangbo Shu

Research Collection School Of Computing and Information Systems

Vision-and-Language Navigation in Continuous Environment (VLN-CE) requires an agent to follow language instructions to navigate the target destination. With the advancement of large language models (LLMs), recent efforts have explored adapting them for zero-shot VLN-CE, offering a promising solution in addressing the drawbacks of poor generalization in the training-based paradigm. However, existing LLM-based works primarily perform naive reasoning for decision-making and lack feedback, e.g., reviewing historical errors and predicting future potentials. Consequently, it may suffer from continuous failure for those initial error tasks. In this paper, we rethink LLM-based zero-shot VLN-CE and propose a new paradigm, named EvoNav, to improve …

The Mystical Soundscape And The Functions Of Commentaries On Ibn Al-Fāriḍ’S (D. 632/1235) Naẓm Al-Sulūk, Sherine Mohsen Aboulwafa

Theses and Dissertations

This thesis examines Ibn al-Fāriḍ’s Naẓm al-Sulūk and its earliest commentaries by al-Farghānī (d. 700/1300) and al-Tilimsānī (d. 690/1291) through the analytical framework of the mystical soundscape. Rather than treating the poem and its commentaries as static texts, it argues that meaning in this corpus emerges as an experiential and perceptual event sustained through sound, silence, and reception. The mystical soundscape is conceptualized as comprising two interrelated domains: a silent soundscape, formed through reading, memory, imagination, and conceptual engagement; and an audible soundscape, formed through recitation, pronunciation, rhythm, and communal audition. These domains are linked by the experience of bewilderment …

When Robots Read Westlaw: Linking Inputs And Outputs In Generative Ai Fair Use Analysis, Aaron Lam

Vanderbilt Journal of Entertainment & Technology Law

Generative artificial intelligence has revealed a novel tension in copyright law: a two-stage act (input and output) of copying that traditional fair-use doctrine never squarely anticipated. In the input stage, vast swaths of copyrighted expression are reproduced and ingested to train large language models. In the output stage, those models generate works that may substitute for or dilute the market of the originals. Courts now face both stages. Their rulings diverge when they consider training and outputs together. In Bartz v. Anthropic PBC and Kadrey v. Meta Platforms, Inc., the courts characterized training uses as “highly transformative,” yet reached opposite …

The Impact Of Religious Behaviors, Islamophobia, Gender Roles, Language Proficiency, And Education Levels On Mental Illness Stigma And Help-Seeking Behaviors Among Arab Women In The U.S., Rima Muhsen

Dissertations

The official U.S. census does not provide data on the number of Arab Americans in the United States, which hinders studies that focus on this population group to explore their needs and improve access to mental health services. Arab women in America represent a subgroup that has received insufficient attention from researchers, particularly regarding culturally sensitive topics such as mental health problems and their associated stigma. The influence of cultural, social, and religious factors on self-stigma associated with mental illness has not been adequately studied among this marginalized group. While previous research has suggested a relationship between self-stigma, social stigma …

Linking (Imagined) Communities: World Language Students' Stereotypical Attributions To Native Speakers And Teachers Of German., Lucian Rothe

Faculty and Staff Scholarship

Abstract This study explores language learners' stereotypical descriptions of native speakers (NSs) of German and their relationship with participants' perceptions of teachers of German. It expands motivation research that employs stereotypes to gain insight into university students' views of target language (TL) speakers (Rothe, 2022, 2025). Sixty‐seven learners of German and 43 learners of other world languages (WLs) pro vided responses about NSs and instructors, while also rating the stereotypes' perceived accuracy. Participants held various stereotypical notions about NSs, reflecting broader societal narratives. Learners of German pro vided more detailed stereotypical descriptions. Both groups considered favorable stereotypes as more accurate …

La Espiritualidad: Transmitting Peruvian Culturo-Spiritual Elements Into Occidental Systemic Spaces, Deisy Amorin-Woods

Research outputs 2022 to 2026

This paper is a decolonising, Indigenous qualitative inquiry that integrates elements of critical autoethnography, narrative methods and conceptual analysis to explore how Peruvian Andean cosmology can inform contemporary systems thinking and family therapy practice. Writing as a mestiza, a Peruvian migrant in Australia, the author traces the lived experience of cultural erosion within Western, individualistic contexts and her reconnection with ancestral Andean teachings. These teachings—rooted in reciprocity, ecological attachment, collective responsibility and relational balance—are presented as living epistemologies that offer timely contributions to working therapeutically. The author examines core Andean concepts including ayll (kinship-based community), ayni (sacred reciprocity), Yachay (aprenderes …

The Vanishing Economics Of Trade Secret Value, Gregory M. Dickinson

Missouri Law Review

Trade secret law is built around a simple economic fact. Information can yield supracompetitive returns only when prospective competitors are prevented from using it, such as when it is kept secret from them. A successful trade secret plaintiff must therefore show that the alleged trade secret derives “independent economic value” from not being generally known to others. Yet modern doctrine sometimes treats this value requirement as something else—an inquiry into whether information is “valuable” in the abstract and whether it is independently useful versus dependent on some other information. Part of the reason is simply that proof of trade secret …

Making The Party Presentation Principle Safe For Originalism, Randy E. Barnett, Lawrence B. Solum

Faculty Scholarship

The Supreme Court sometimes adheres to what it calls the “party presentation principle”—terminology that dates back to 2008. Although judicial articulations of the principle have been inconsistent and imprecise, the gist is the familiar notion that courts should resolve cases on the basis of the issues and reasons presented by the parties to the dispute. Conversely, questions not properly raised by the parties should be avoided by the Court. Thus, the Court has on several occasions declined to address arguments outside the scope of the questions raised by the parties in their petition for certiorari.

For originalists, the importance of …

“Hip-Hop Permeates Everything I Do:” The Intersections Of Global Politics, Hip-Hop, And Education, Mecedes Lindsay

Black Educology Mixtape "Journal"

This qualitative study examines how the absence of Critical Hip-Hop Pedagogy (CHHP) within academic institutions shapes students’ sense of belonging, motivation, and engagement by regulating which forms of cultural capital are deemed legitimate. Drawing on semi-structured interviews and focus groups with students, educators, scholars, and members of the hip-hop generation, this research adopts an interpretivist framework to center participants’ lived experiences within educational spaces. Informed by Freirean critical pedagogy and Yosso’s theory of community cultural wealth, the study situates schooling as a site where America’s soft power operates through curriculum design, disciplinary norms, and definitions of deviance. Findings reveal that …

Purposefully Black Interactional Systems: Disrupting Punitive School Discipline Models Through Banter, The Funk, And The Black Aesthetic, S. M. Wilson

Black Educology Mixtape "Journal"

This empirical study seeks to understand the narratives of four Black men teachers and two Black women teachers about how they implement school discipline and classroom management in their K–12 contexts. This track draws on interdisciplinary perspectives from education, linguistic anthropology, and African American studies to understand how banter and ritual insults function as alternatives to traditional discipline. Phenomenology and thematic analysis of six semistructured interviews demonstrated Black teachers’ beliefs that outdated and punitive orientations should be challenged. These teachers enacted discipline through talk—particularly banter, ritual insults, and what I call “purposefully Black interactional systems,” which embed discipline within them, …

Harriet Tubman’S Underground Railroad As Ancestral Technology For Black Futures, Julia Lynch

Black Educology Mixtape "Journal"

This track draws on BlackMothering to frame Harriet Tubman not only as a conductor of freedom but as an architect of ancestral technology, designing strategies of survival that continue to instruct contemporary struggles. Tubman’s praxis—relational, anticipatory, and collective—illuminates the enduring power of Black knowledge systems to chart pathways through systems of violence and oppression. In conversation with Tiffani Marie and Kenjus Watson’s theorization of Apocalyptic Education and what Django Paris and H. Samy Alim describe as culturally sustaining pedagogy, this track explores how Tubman’s Underground Railroad praxis offers a blueprint for Black sustainability using (a) health and survival, (b) spatial …

Embodied Archives: The Body As Technology Of Black Sustainability, Felicia Rutledge

Black Educology Mixtape "Journal"

This track develops the concept of embodied archives as technologies of Black sustainability in apocalyptic times. Building from Diana Taylor’s distinction between the archive and the repertoire, and in conversation with Hortense Spillers, Saidiya Hartman, Christina Sharpe, Sami Schalk, Tiffani Marie and Kenjus Watson, and Ruha Benjamin, I argue that Black bodies function as living repositories of knowledge. Long before schools claimed authority over learning, communities preserved memory in movement, rhythm, oral and signed languages, tactile practices, and everyday rituals of care. Disabled Black bodyminds, through practices such as braille literacy and augmentative and alternative communication, further illustrate how assistive …

Dancing In The Wake | Like Moss Over Modernity, Simple Ant

Black Educology Mixtape "Journal"

This offering is a meditation on existing and thriving in the wake of civilization. For centuries, we have educated one another to believe in, and glorify, the insatiable desires of our modern way of life. I begin with the premise that what we call “civilization” is a system predicated on death, violence, and exploitation, because it requires the endless extraction and consumption of the living Earth. Living in this way guts the Earth to feed our ideas of “progress” and “prosperity.” The effect now is that our civilization, our society, our way of life is rotting—bringing with it decay and …

Claiming Estevanico De Azamor In The Labyrinth Of Oriental/Western Identities, Khalid Chaouch

SOROUD: The journal of Literacy Criticism

This article discusses the multilayered identity of Estevanico, a sixteenth-century Moroccan enslaved from Morocco and one of four survivors of a Spanish expedition to America. His biography disrupts fixed ideas about culture and race, showing how he crossed linguistic, cultural, and geographical boundaries. The paper critiques the multiple claims made over his identity and argues that placing him within Orientalist or Occidentalist frameworks is futile. Estevanico’s life demonstrates the value of intercultural understanding, adaptability, dialogue, and acceptance beyond racial or identity claims.
