A Standard Livestock Unit (Slu) For Defining Stocking Rate In Grazing Studies, D J. Minson, P C. Whiteman

IGC Proceedings (1977-2023)

The weight of animals and hence their intakes vary between grazing experiments and at different stages of the same study but the results are often presented as though these differences do not affect grazing pressure (Roberts, 1980). Thus we have sheep/ha and cattle/ha, with no indication of the effects that differences in intake and hence grazing pressure might have on the pasture/animal interaction. Pastures are utilized by different classes of stock and there is a need to have a common basis for comparing their productivity. These problems would be over­come by the use of a Standard Livestock Unit (SLU).

Pharmacogenetic-Guided Antiplatelet Therapy For Personalized Medicine In Patients With Stroke And Transient Ischemic Attack Without Cardioembolic Stroke: A Systematic Review Of Economic Evaluations, Nathapol Samprasit, Chamipa Phanudulkitti, Nattanichcha Kulthanachairojana, Jatapat Hemapanpairoa

The Thai Journal of Pharmaceutical Sciences

Background: Stroke is a major global public health burden. Ischemic stroke is the most common type of all stroke cases worldwide. Antiplatelet therapy is a key strategy for secondary prevention in patients with stroke and transient ischemic attacks (TIAs) without cardioembolic stroke. Dual antiplatelet therapy (DAPT) with clopidogrel is recommended in patients with early mild stroke or high-risk TIA, followed by long-term single antiplatelet therapy (SAPT). Clopidogrel is often used as an alternative for patients with aspirin resistance or intolerance. However, clopidogrel is a prodrug metabolized by the CYP2C19 enzyme, leading to variability in its effectiveness.

Objectives: This study aims …

Variable Importance, Knockoff Filters, And Improving False Discovery And False Negative Rates, Nicholas Ehlman

Dissertations

Tree ensemble methods such as Random Forests and Boosted Trees have introduced a range of variable importance statistics, offering powerful tools for feature selection. The advent of knockoff filters marked a significant advancement by combining the use of these variable importance statistics with the ability to control the False Discovery Rate (FDR). However, achieving a low FDR frequently comes at the cost of a high False Negative Rate (FNR), limiting the power of such approaches. In this work, we propose a novel method for leveraging knockoff variables to keep both FDR and FNR low. While this method does not have …

Pinterest Can Help Teachers Cook A Casserole, But What About Lgbtqia+ Affirming Lesson Plans For Students Of Color?, Denise Villarrial Nealon

Deliberately Queer Journal

We have learned to be crafty homemakers, small space decorators, and even teachers through the eye-catching appeal of sites like Pinterest or Teachers Pay Teachers (TPT). The accessibility and ease of searching for a preset lesson saves time, and in a society where teachers are paid far less than what they are worth and asked to work longer hours than they are paid for, this makes sense. Using the theoretical frameworks of CRT, QueerCrit, and CRP, along with the concepts of intersectionality, can build learning tools for new teachers to disrupt previous exclusionary practices that prevent LGBTQIA+ students of Color …

Combining Submicron Spectroscopy Techniques (Afm-Ir And O-Ptir) To Detect And Quantify Nanoplastics In Snow From A Utah Ski Resort, Sara L. Belontz, Janice Brahney, Caroline E. Caplan, Eoghan Dillon, Ting Yan, Gerardo Dominguez

Watershed Sciences Faculty Publications

Atomic force microscopy-based infrared spectroscopy (AFM-IR) and optical photothermal infrared (O-PTIR) spectroscopy are cutting-edge techniques used for precise nanoscale chemical analysis, capable of detecting and characterizing particles smaller than 1 μm. In this study, we applied both techniques to analyze snow subsamples collected from Beaver Mountain, Utah. Quantification by AFM-IR identified a concentration of 1.50 × 10^–1 μg/mL of poly(3-hydroxybutyrate-co-4-hydroxybutyrate), a copolyester known for its biodegradability and biocompatibility and that was the only polymer detected. Notably, 96% of particles had thicknesses below 1 μm, with the smallest particle recorded at 14 nm in height, demonstrating the advantage …

Directivity And Sound Radiation Of Percussion Instruments And Harmonic Analysis Of The Alto Saxophone, Hanna Michelle Pavill

Theses and Dissertations

This thesis investigates how musical instruments radiate sound, with a focus on directional behavior under realistic performance conditions. High-resolution measurements using a rotating microphone array were used to study percussion and woodwind instruments, providing new insight into how design, excitation, and frequency content shape acoustic output. The first set of experiments analyzed the directivity of the bass drum, triangle, and open snare. Each instrument exhibited unique radiation patterns reflecting its structure and playing method. The bass drum showed dipole-like behavior at low frequencies, transitioning to omnidirectional spreading at mid frequencies, and increasingly irregular patterns at higher frequencies. The triangle, due …

Strategies Minority Small Business Owners Use To Obtain Access To Capital, Marchelle Ronique Yearby

Walden Dissertations and Doctoral Studies

Minority small business owners (MSBOs) often experience significant challenges in securing business capital, which is critical for sustaining and growing their businesses. MSBOs are concerned with the lack of business capital because it restricts their ability to expand operations, innovate, and generate employment within their communities. The purpose of this qualitative multiple-case study, which was grounded in the financial inclusion theory, was to identify and explore strategies MSBOs employ to secure access to capital. The participants were nine MSBOs in the Southeastern United States, each of whom had successfully maintained and secured working capital to sustain a profitable business for …

An Exploratory Analysis Of Automated Deception Detection For Mental Health Applications, Sayde Leya King

USF Tampa Graduate Theses and Dissertations

Deception in mental health settings can undermine therapeutic relationships, compromise treatment efficacy, and impact patient outcomes. Yet, research shows that mental health clinicians often perform no better than chance at detecting deceptive behavior in therapy. Automated deception detection, leveraging artificial intelligence (AI) and multimodal behavioral cues—such as eye gaze, body gestures, and facial expressions—offers a promising alternative. However, most existing research focuses on high-stakes legal contexts, limiting its applicability to mental health settings.

This dissertation addresses this gap by pursuing three key research objectives using a mixed-methods approach. First, we investigate mental health clinicians’ perspectives on AI-assisted deception detection through …

Efficient Methods And Algorithms For Analyzing Stochastic Systems, Mohammad Ahmadi

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the challenges of stochastic analysis of safety-critical systems with biological components, where unexpected behavior can lead to catastrophic events. Two fundamental challenges hinder the analysis of such systems: their typically large or infinite state spaces, and the extreme rarity of error states of interest. While Monte Carlo simulation can analyze biochemical systems without storing the state space, accurately estimating rare event probabilities becomes computationally prohibitive. Conversely, probabilistic model checking excels at analyzing extremely low probability events but becomes impractical for systems with large or infinite state spaces due to memory constraints.This work proposes two main contributions to …

The Myth Of The Bayesian Brain, Madhur Mangalam

Journal Articles

The Bayesian brain hypothesis—the idea that neural systems implement or approximate Bayesian inference—has become a dominant framework in cognitive neuroscience over the past two decades. While mathematically elegant and conceptually unifying, this paper argues that the hypothesis occupies an ambiguous territory between useful metaphor and testable, biologically plausible mechanistic explanation. We critically examine the key claims of the Bayesian brain hypothesis, highlighting issues of unfalsifiability, biological implausibility, and inconsistent empirical support. The framework’s remarkable flexibility in accommodating diverse findings raises concerns about its explanatory power, as models can often be adjusted post hoc to fit virtually any data pattern. We …

Non-Discriminatory Personalized Pricing, Philipp Strack, Kai Hao Yang

Cowles Foundation Discussion Papers

A monopolist offers personalized prices to consumers with unit demand. Consumers differ in their values, costs, and \emph{protected characteristics}---such as race or gender. The seller is subject to a non-discrimination constraint: consumers with the same cost, but different protected characteristics must face identical price distributions. Such regulations are present in markets like credit or insurance. We characterize the optimal pricing rule. Under this rule, surplus accrues to both protected groups, but only to those with intermediate values. Strengthening the constraint to cover transaction prices redistributes surplus, harming the low-value group and benefiting the high-value group. Meanwhile, prohibiting the use of …

Grid Fragility, Blackouts, And Control Co-Design Solutions, Mario Garcia-Sanz

Faculty Scholarship

The grid is undergoing a large-scale transformation, including a significant reduction of synchronous generators, a high penetration of inverter-based resources and renewables, substantial demand growth, new extra-large loads, aging infrastructure and a concerning vulnerability to contingencies. Some of the recent massive blackouts in Spain/Portugal, Chile and Texas are exposing the fragility of the grid as we know it today. This paper introduces new solutions to stabilize the grid under undesired dynamic interactions and extreme contingencies, with the goal of avoiding cascading failures and blackouts. Using control co-design methodologies, the paper proposes three interdependent categories to improve the reliability and controllability …
