Wheat (Triticum aestivum L.) is a vital food crop for majority of the world's population. However, its yield potential is significantly threatened by insect pests, which adversely affect production, quality, and overall food security. The diverse array of insect pests throughout wheat's growth stages necessitates a comprehensive understanding of their interactions with wheat cultivation. This review critically assesses the diversity, biology, ecology, and management strategies of major insect pests in North India, including aphids, termites, pink stem borer, gram pod borer, armyworm, and brown wheat mite. These pests infest wheat at various growth stages, posing significant challenges to sustainable production. …


The Temporal Dynamics Of Attention To Threat And Gad Symptoms: A Study Of Lpp Slopes, Ben Swanson, Matt R. Judah, Grant S. Shields Oct 2025

The Temporal Dynamics Of Attention To Threat And Gad Symptoms: A Study Of Lpp Slopes, Ben Swanson, Matt R. Judah, Grant S. Shields

Psychological Science Faculty Publications and Presentations

Individuals experiencing generalized anxiety disorder (GAD) show heightened attention to threat, as suggested by greater amplitude of the late positive potential (LPP). However, amplitude measurements do not fully capitalize on the high temporal resolution of EEG. Specifically, amplitude does not reflect the rate of change in the LPP over a window of interest, which may be important to understand LPP dynamics in individuals with GAD. Indeed, this rate of change of the LPP (i.e., LPP slope) may reflect attentional orienting. The current study leveraged multilevel models to examine the LPP in relation to GAD symptoms. We hypothesized that more-positive LPP …


Faith Vs. Morality: Do Viewpoints Of Protestant Christians Attending Psu Align With Anti-Transgender Legislation Being Proposed In Oregon?, Asher Schneider Oct 2025

Faith Vs. Morality: Do Viewpoints Of Protestant Christians Attending Psu Align With Anti-Transgender Legislation Being Proposed In Oregon?, Asher Schneider

University Honors Theses

Transgender-identifying individuals living within the US face significantly higher rates of discrimination and harassment compared to the general US population. Recently, there have been thousands of legislative measures introduced with the intent of limiting the rights of Transgender and other LGBTQ identifying individuals. Christian Americans are significantly more likely than irreligious Americans to be against various rights for Transgender people, such as the ability to participate in sports or use restrooms that correlate with their self-identified gender rather than their biological sex. Research indicates that recent anti-transgender legislative measures introduced in several states is in part driven by the large …


Mama, Appa, And Titi: What Makes Words Sound Parental? A Phonological Exploration Of Parental Terms In And Beyond The Gender Binary, Madeleine C. S. Kruckemeye , '26 Oct 2025

Mama, Appa, And Titi: What Makes Words Sound Parental? A Phonological Exploration Of Parental Terms In And Beyond The Gender Binary, Madeleine C. S. Kruckemeye , '26

Senior Theses, Projects, and Awards

This paper addresses the following research question: What phonological components make a word sound ‘parental’ cross-linguistically and (how) do those components relate to the social genders associated with the word? The goal in answering this question is to extend Jakobson (1960) and Murdock’s (1959) work to be inclusive of our current understanding of gender and gender roles, and to create more options for queer parents and other families that are recognizable as parental terms, an important factor as found by Frank et al. (2017). The research consists of a literature review, an analysis of cross-linguistic parental terms, and an online …

Internal Medicine, East Africa

The epidemiology of neuroimmunological disorders in Africa remains poorly understood. Regional variation in diagnostics and provider knowledge has led to challenges in real-world application of diagnostic criteria. We conducted a cross-sectional survey of clinicians practicing in Africa to characterize the current state of clinical diagnostic resources and developed a clinician-driven prioritized action plan. 130 respondents from 24 out of 54 countries in Africa participated (44% national response rate). Most respondents specialized in neurology (n = 86, 66%) and practiced in an urban setting (n = 84, 65%). While all participating countries had access to a neurologist and ophthalmologist, only half …


Lost In Translation: Chomskyan Analysis Of Language Variation In Ai, Post-Critical Learners, And Native Speakers, Hannah Van Rijnswou Oct 2025

Lost In Translation: Chomskyan Analysis Of Language Variation In Ai, Post-Critical Learners, And Native Speakers, Hannah Van Rijnswou

Holster Scholar Projects

Artificial Intelligence (AI) and Large Language Models (LLMs) have revolutionized linguistic theory, raising questions about human language acquisition. Some argue AI's language generation challenges the concept of innate linguistic ability, while others contend it reinforces it. This research examines AI's "Surplus of the Stimulus" learning—relying on vast datasets—against human language acquisition, particularly within Chomskyan frameworks of Universal Grammar and the "Poverty of the Stimulus." By analyzing language production across three groups—Native English Speakers, Post-Critical Period Second Language Learners, and LLMs—this study compares linguistic complexity using the Lexical Opulence Index (LOI). Data is collected through structured prompts across four linguistic registers: …

“Sometimes I Have To Figure Things Out By Talking About Them”: Conceptualizing Think-Aloud Protocols As Spaces For Reflexivity During Open Textbook Construction, Dawn Atkinson, Stacey Corbitt Oct 2025

“Sometimes I Have To Figure Things Out By Talking About Them”: Conceptualizing Think-Aloud Protocols As Spaces For Reflexivity During Open Textbook Construction, Dawn Atkinson, Stacey Corbitt

Writing

Abstract Open textbooks, freely available open educational resources, have an ever-growing presence in learning environments around the world, though detailed studies of their development are rare. The challenges of tracking textbook writing activity in a precise manner over time may account for this sparsity. To highlight how process-tracing research can contribute insight to the textbook development literature, particularly that focused on open textbook writing, this study addresses the roles that think-aloud protocols (TAPs) played during the construction of an open corequisite writing textbook. The volume, which was designed with underprepared university students in mind, stresses the growth of academic and …

Controls without narcolepsy were matched in a 1:4 …


Menopause Factors And Alterations In Gut Microbiota And Insulin Homeostasis: A Cross-Sectional Analysis Of The Microbiome And Insulin Longitudinal Evaluation Study (Miles), Vincent J Maffei, Alain G Bertoni, Alexis C Wood, Jerome I Rotter, Osa Crago, Yii-Der I Chen, Joseph F Petrosino, Kristi L Hoffman, Mark O Goodarzi, Elizabeth T Jensen Oct 2025

Menopause Factors And Alterations In Gut Microbiota And Insulin Homeostasis: A Cross-Sectional Analysis Of The Microbiome And Insulin Longitudinal Evaluation Study (Miles), Vincent J Maffei, Alain G Bertoni, Alexis C Wood, Jerome I Rotter, Osa Crago, Yii-Der I Chen, Joseph F Petrosino, Kristi L Hoffman, Mark O Goodarzi, Elizabeth T Jensen

Children’s Nutrition Research Center Staff Publications

Aim: To assess the risk for impaired insulin homeostasis as a function of menopause-related factors and gut microbiota dysbiosis in non-diabetic, post-menopausal women.

Materials and methods: Baseline data (n = 175 women) from the Microbiome and Insulin Longitudinal Evaluation Study (MILES) were used, including insulin and dysglycaemia indices calculated from a 2-h oral glucose tolerance test, untargeted peripheral metabolomics, targeted peripheral short chain fatty-acid levels and faecal bacterial microbiota surveyed by whole-metagenomic sequencing.

Results: After adjustment for covariates, menopause age < 50 years and use of hormone replacement therapy (HRT) were associated with lower Matsuda et al. insulin sensitivity index levels (β = -0.232, confidence interval (CI) = [-0.450, -0.014] and β = -0.275, CI = [-0.444, -0.107], respectively) but not pre-menopausal gynaecologic surgery. Pre-menopausal gynaecologic surgery was significantly associated with faecal microbiota beta diversity driven by a relative increase in diabetogenic Ruminococcus gnavus and Clostridium species and a decrease in protective Alistipes species and Akkermansia muciniphila relative abundances. A reduction in two glycerophospholipids in the plasmalogen class significantly statistically mediated an inverse association between gynaecologic surgery before menopause and insulin sensitivity.

Conclusions: Menopause age and history of HRT are more strongly associated with insulin resistance than gynaecologic surgery before menopause. However, …


Is Your Data Good, Bad, Or Neutral?: Redefining Concreteness For Data Breach Harms, Jeeyoon Lim Oct 2025

Is Your Data Good, Bad, Or Neutral?: Redefining Concreteness For Data Breach Harms, Jeeyoon Lim

Fordham Law Review

In recent years, the Supreme Court has tightened federal court standing requirements for intangible harms, including statutory harms. In TransUnion LLC v. Ramirez, the Court held that a mere statutory violation, absent a common-law analogue, is not sufficiently concrete to grant standing. The Court did not provide clear guidance as to how stringent the common-law analogue analysis must be, other than that it does not require an “exact duplicate.” Because of the ever-evolving nature of digital data, data breach victims attempting to enforce their statutory right to privacy in federal court have struggled to rely on tradition and history …

Research Collection School of Social Sciences

Mexican-origin families often face economic hardship due to systemic oppression, increasing the likelihood of adolescent marijuana use. While the family stress model provides insight into the mechanism of the association between family economic hardship and adolescent marijuana use, resilience factors are relatively unknown. The present study uses a three-wave longitudinal data set of Mexican immigrant families in the United States (Wave 1—adolescents: Mage = 12.29, SD = 0.93; mothers: Mage = 38.57, SD = 5.71) to investigate the mechanism underlying the association between family income and adolescents’ likelihood of marijuana use, guided by the family stress model. The protective role …


A 3-Item Short Version Of The Fear Of Missing Out (Fomo) Scale For Trait And Time-Intensive Designs: Measurement Invariance And Psychometric Properties, Eva M. Hisham, Andree Hartanto, Nadyanna M. Majeed Oct 2025

A 3-Item Short Version Of The Fear Of Missing Out (Fomo) Scale For Trait And Time-Intensive Designs: Measurement Invariance And Psychometric Properties, Eva M. Hisham, Andree Hartanto, Nadyanna M. Majeed

Research Collection School of Social Sciences

Research on Fear of Missing Out (FoMO) has gained prominence alongside the rise of digital connectivity and social media, which offer individuals continuous access to others’ experiences in real time. Importantly, it has been increasingly recognised as an important psychological construct, closely associated with various problematic digital behaviours. As the fields of media psychology and human-computer interaction increasingly adopt time-intensive methodologies (e.g., daily and weekly studies) to capture dynamic experiences of technology use, there is a growing need for brief yet psychometrically-sound measures of FoMO suitable for such designs. The present work reports the development of a 3-item FoMO scale …

In recent years, applying deep models to automatically learn construction heuristics for vehicle routing problems has achieved remarkable advancements. However, they are less effective in searching solutions due to two primary limitations: relying on deterministic probability distributions and overlooking the strategic advantage of prioritizing nearby unvisited nodes during the route construction process, resulting in suboptimal policies In this paper, we propose a novel lightweight population-based policy optimization (LPPO) framework that learns a diverse population of solution strategies through the utilization of innovative perturbation factors, in order to facilitate search exploration. Moreover, we design a localized attention synthesis (LAS) network to …


Classical Shadows With Improved Median-Of-Means Estimation, Winston Fu, Dax Enshan Koh, Siong Thye Goh, Jian Feng Kong Oct 2025

Classical Shadows With Improved Median-Of-Means Estimation, Winston Fu, Dax Enshan Koh, Siong Thye Goh, Jian Feng Kong

Research Collection School Of Computing and Information Systems

The classical shadows protocol, introduced by Huang et al (2020 Nat. Phys. 16 1050), makes use of the median-of-means (MoM) estimator to efficiently estimate the expectation values of M observables with failure probability δ using only O ( log ⁡ ( M / δ ) ) measurements. In their analysis, Huang et al used loose constants in their asymptotic performance bounds for simplicity. However, the specific values of these constants can significantly affect the number of shots used in practical implementations. To address this, we studied a modified MoM estimator proposed by Minsker (2023 Proc. 36th Conf. on Learning Theory …

Look Before You Decide: Prompting Active Deduction Of Mllms For Assumptive Reasoning, Yian Li, Wentao Tian, Yang Jiao, Jingjing Chen, Tianwen Qian, Bin Zhu, Na Zhao, Yu‑Gang Jiang

Research Collection School Of Computing and Information Systems

Recently, Multimodal Large Language Models (MLLMs) have achieved significant success across multiple disciplines due to their exceptional instruction-following capabilities and extensive world knowledge. However, whether these MLLMs possess human-like compositional reasoning abilities remains an open problem. To unveil their reasoning behaviors, we first curate a Multimodal Assumptive Reasoning Benchmark (MARS-Bench) in this paper. Interestingly, we find that most prevalent MLLMs can be easily fooled by the introduction of a presupposition into the question, whereas such presuppositions appear naive to human reasoning. Besides, we also propose a simple yet effective method, Active Deduction (AD), a novel reinforcement learning paradigm to encourage …

Memory-Efficient 4-Bit Preconditioned Stochastic Optimization, Jingyang Li, Kuangyu Ding, Kim-Chuan Toh, Pan Zhou

Research Collection School Of Computing and Information Systems

Preconditioned stochastic optimization algorithms, exemplified by Shampoo, outperform first-order optimizers by offering theoretical convergence benefits and practical gains in large-scale neural network training. However, they incur substantial memory overhead due to the storage demands of non-diagonal preconditioning matrices. To address this, we introduce 4-bit quantization for Shampoo’s preconditioners. We introduce two key methods: First, we apply Cholesky decomposition followed by quantization of the Cholesky factors, reducing memory usage by leveraging their lower triangular structure while better preserving spectral properties to minimize information loss. To our knowledge, this is the first quantization approach applied to Cholesky factors of preconditioners. Second, we …


Probabilistic Prototype Calibration Of Vision-Language Models For Generalized Few-Shot Semantic Segmentation, Jie Liu, Jiayi Shen, Pan Zhou, Jan-Jakob Sonke, Stratis Gavves Oct 2025

Probabilistic Prototype Calibration Of Vision-Language Models For Generalized Few-Shot Semantic Segmentation, Jie Liu, Jiayi Shen, Pan Zhou, Jan-Jakob Sonke, Stratis Gavves

Research Collection School Of Computing and Information Systems

Generalized Few-Shot Semantic Segmentation (GFSS) aims to extend a segmentation model to novel classes with only a few annotated examples while maintaining performance on base classes. Recently, pretrained vision-language models (VLMs) such as CLIP have been leveraged in GFSS to improve generalization on novel classes through multi-modal prototypes learning. However, existing prototype-based methods are inherently deterministic, limiting the adaptability of learned prototypes to diverse samples, particularly for novel classes with scarce annotations. To address this, we propose FewCLIP, a probabilistic prototype calibration framework over multi-modal prototypes from the pretrained CLIP, thus providing more adaptive prototype learning for GFSS. Specifically, FewCLIP …


From Holistic To Localized: Local Enhanced Adapters For Efficient Visual Instruction Fine-Tuning, Pengkun Jiao, Bin Zhu, Jingjing Chen, Chong-Wah Ngo, Yugang Jiang Oct 2025

From Holistic To Localized: Local Enhanced Adapters For Efficient Visual Instruction Fine-Tuning, Pengkun Jiao, Bin Zhu, Jingjing Chen, Chong-Wah Ngo, Yugang Jiang

Research Collection School Of Computing and Information Systems

Efficient Visual Instruction Fine-Tuning (EVIT) seeks to adapt Multimodal Large Language Models (MLLMs) to downstream tasks with minimal computational overhead. However, as task diversity and complexity increase, EVIT faces significant challenges in resolving data conflicts. To address this limitation, we propose the Dual Low-Rank Adaptation (Dual-LoRA), a holistic-to-local framework that enhances the adapter’s capacity to address data conflict through dual structural optimization. Specifically, we utilize two subspaces: a skill space for stable, holistic knowledge retention, and a rank-rectified task space that locally activates the holistic knowledge. Additionally, we introduce Visual Cue Enhancement (VCE), a multi-level local feature aggregation module designed …
