Road Salt Alters The Ecological Effects Of Atrazine-Cypermethrin Mixtures In Freshwater Microalgae Mixtures In Freshwater Microalgae, Arif Ahmed, Matthew S Schuler

Department of Biology Faculty Scholarship and Creative Works

Pesticides and road deicing salts are widespread contaminants in freshwater systems and frequently co-occur due to runoff and direct application. Atrazine, a triazine herbicide, and sodium chloride (NaCl), commonly used for road deicing, can independently alter water chemistry and affect aquatic primary producers. Atrazine can affect the freshwater algae, either inhibiting or stimulating their growth. The prolonged persistence of dissolved salts, ranging from decades to centuries, can lead to complex environmental scenarios characterized by multiple interacting stressors. Although many studies have examined each pollutant separately, their interactive effects have only recently gained scientific attention. This study investigated the individual and …

Leveraging Blockchain And Llms For Patient–Clinical Trial Matching, Diana Hawashin, Khaled Salah, Raja Jayaraman, Samer Ellahham, Ibrar Yaqoob

Industrial Engineering: Faculty & Staff Publications

Efficiently matching patients to clinical trials is essential for advancing medical research and ensuring reliable outcomes. However, current matching methods face several challenges. These include data integrity issues from tampered records, privacy risks caused by weak anonymization, and manual processes that delay recruitment. In addition, centralized systems lack transparency, expose sensitive patient data to security vulnerabilities, and suffer from single points of failure that reduce resilience and trust. In this paper, we propose a blockchain and Large Language Models (LLMs)-driven solution for secure, trustworthy, traceable, decentralized, and transparent patient-clinical trial matching. Blockchain ensures data integrity, security, and transparency by eliminating …

Resurrecting Immigration Releases, Lindsay Nash

Articles

The nation’s “mandatory” immigration-detention laws sustain its largest civil-imprisonment system—and just radically expanded in scope and breadth. These laws consign broad swaths of suspected noncitizens to no-bail pretrial detention, denying tens of thousands of people facing civil regulatory charges any chance to prove they need not be detained. These laws turn split-second arrest decisions into jail sentences. They force people to give up meritorious claims. And they confound the historic presumptions—liberty, innocence, prosecutorial discretion, and bail—that undergird other pretrial-detention regimes. Although mandatory immigration detention conflicts with fundamental constraints on analogous detention regimes, the Supreme Court has treated it as exceptional …

(Si16-04) Some Fixed Point Theorems On Chatterjea Type Contractions, Irom Shashikanta Singh, Y. Mahendra Singh

Applications and Applied Mathematics: An International Journal (AAM)

This paper establishes the existence of fixed points related to strict Chatterjee contractive mappings by relaxing the compactness of the underlying spaces and the continuity of the mapping involved, using altering distance functions and comparison functions in the general setting of metric spaces. Several non-trivial and illustrative examples are provided to demonstrate, support, and validate the obtained theoretical results. In addition, a theorem that can characterize the completeness of metric spaces through the existence of fixed points is rigorously proven and discussed. Furthermore, a theorem on strict Chatterjea-type modulus contractive mappings without continuity assumptions and with relaxed compactness conditions is …

(Si16-06) Equations Of Geodesics In Two-Dimensional Finsler Manifold With A Special Cubic (Α, Β)-Metric, Sejal Prajapati, Brijesh Kumar Tripathi, V. K. Chaubey

Applications and Applied Mathematics: An International Journal (AAM)

Geodesics represent the shortest path between two points in curved spacetime and are vital in the study of Finsler manifolds. Matsumoto and Park first derived the geodesic equation as a secondorder differential equation in a two-dimensional Finsler manifold with Randers, Kropina, and Matsumoto metrics. Building on this foundation, our paper presents the geodesic differential equation for a two-dimensional Finsler manifold using a special cubic power metric. In this two-dimensional setting, this work also looks at certain well-known geometric curves and analyzes their variants as solutions to the geodesic differential equation. Additionally, this work examines the geometric applications of the geodesic’s …

(Si16-07) Computing The Kirchhoff Index And The Wiener Index Of Spiro Para Hexagonal Cylinder Chain, Md Selim Reja, Sk. Md. Abu Nayeem

Applications and Applied Mathematics: An International Journal (AAM)

In graph theory, the Kirchhoff index serves as a metric to evaluate the complexity of a graph. It is determined by adding up the resistance distances between every pair of vertices in the graph. In a network created from the given graph by substituting each edge by a unit resistor, the resistance distance between a pair of specified vertices is equivalent to the electrical resistance between them in the constructed network. Basically, it measures the convenience with which data or flow can move between various locations in a network that the graph represents. In terms of graph matrices, the Kirchhoff …

Stemflow Dynamics In The Jamari National Forest (Brazilian Amazon): Ii. Solute Concentrations And Flux Dynamics, Jeferson Alberto De Lima, John T. Van Stan Ii, Karolina Lewińska, Agnieszka Dradrach, Jakub Ceglarek, Kelly Cristina Tonello

Biological, Geological, and Environmental Faculty Publications

Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy-derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over a 12-month period in Jamari National Forest (Brazil), we quantified stemflow volume and solute chemistry for 19 trees grouped by diameter at breast height (D: < 10, 10-20 and > 20 cm), crown area (CA: < 30, 30-60 and > 60 m(2)) and bark texture (smooth, fissured and rough). Small-stemmed, smooth-barked trees produced the greatest stemflow …

The Use Of Video Modeling To Teach Algebraic Equations To Secondary Students With And At-Risk For Disabilities, Maria Mcgrath, Emily Hornung, Shannon Gormley Budin

The Journal of Special Education Apprenticeship

Identifying mathematics interventions that are efficient, effective, and increase independence are vital for students with or at-risk for mathematics disabilities. Interventions used in general education or instructional support settings must also be feasible and allow teachers to meet both individual as well as whole-class needs. Digital technologies such as video modeling can embody several high-leverage instructional practices at once to facilitate the learning of fundamental mathematics concepts, such as algebra. A multiple baseline across participant design with an additional nonconcurrent replication in an applied setting was used to evaluate the effectiveness of video modeling on student ability to solve two-step …

The Journal of Special Education Apprenticeship

This practitioner article examines the use of Naturalistic Developmental Behavioral Interventions (NDBIs) to enhance communication skills through the vignette of a 4-year-old with speech delays. Through brief coaching sessions, the child’s parents learned techniques like imitation and prompting, integrating them into daily routines to improve vocal communication. The intervention highlighted the effectiveness of engaging caregivers as active participants and tailoring strategies to family contexts, leading to positive outcomes for both the child and family. This article outlines the procedures for practitioners to coach parents to implement evidence-based practices that can promote academic and behavioral growth in a naturalistic setting.

The Fourth Amendment's Right To Be Secure, Thomas K. Clancy

William & Mary Bill of Rights Journal

Beginning with a 1998 article and through the editions of my treatise, I have argued that the right to be “secure” must be properly understood. The right to be secure is the powerful ability to exclude the government, and it protects against physical and technological intrusions. As will be discussed, my interpretation has had some influence among courts and scholars. Several academics have taken time to discuss it, and it has been noticed in the Supreme Court. This Essay seeks to dispel some of those characterizations and clarify the meaning of the right to be secure.

The Amendment in its …

Ymca Changes Lives: Social Media Campaign, Savannah Nicole Rivera

Communication Studies

This project examines how the YMCA of San Luis Obispo constructs its organizational identity through digital messaging by applying framing theory (Entman, 1993). Drawing from scholarship on framing, nonprofit organizational identity, dual-identity tensions, and nonprofit storytelling, I conduct an applied framing analysis of the YMCA’s website and Instagram content. Specifically, I analyze how the organization defines community problems, attributes causes to them, assigns moral values to them, and proposes solutions in its messaging. I argue that while the YMCA references its mission, its current digital communication often makes utilitarian identity elements, such as services, memberships, and facilities, more salient than …

Pirated Ai Training Data And The Future Of Recovery For Creatives, Cassie Anderson

The Business, Entrepreneurship & Tax Law Review

The explosive growth of generative AI necessarily relies on near-limitless amounts of creative works, such as books, articles, music, and art for training. Data sourcing and training practices advanced by large technology companies have defaulted to piracy, which presupposes unfettered access to high-quality creative data at minimal cost. In a growing number of markets, generative AI presents an appealing alternative to human-made creative works—an alternative that directly competes with the very human creatives whose works are necessary to power such technology. Facing mass-scale piracy and creative markets diluted by AI content, creative professionals are in an even more precarious position …

A Synthetic Marketplace: Rethinking First Amendment Theory In The Age Of Ai-Generated Video, Jared Schroeder, Heesoo Jang

The Business, Entrepreneurship & Tax Law Review

First Amendment theory is unprepared for the synthetic-media era. AI-generated videos, which fundamentally portray events and actions that never happened, are changing the ways people construct reality in fundamental ways. These believable videos raise substantial concerns about foundational assumptions of First Amendment theory, particularly the marketplace of ideas. Synthetic videos challenge citizens to discern truth from falsity in new ways. These challenges are multiplied by the nature of video, which scholars have noted audiences find uniquely believable. This article examines First Amendment theory, as well as the nature of video, ultimately contending that the rationales the Supreme Court has traditionally …

At The Crossroads: Sports Betting In Missouri And Proposals For Regulations, Jimin Shumate

The Business, Entrepreneurship & Tax Law Review

Sports betting is a rapidly growing industry nationwide, and Missouri became the 39th state to legalize the practice. Although states hope to reap the benefits of a regulated sports gambling market, the activity carries significant mental, physical, and socioeconomic risks due to its inherently addictive nature. The hyper-accessibility of modern platforms, particularly those enabling unlimited micro betting, magnifies longstanding concerns in a new digital context. Compounding these risks, the absence of federal standards for minimum wagering ages and the aggressive marketing strategies employed by sportsbooks draw in young adults. This article proposes a coordinated federal and state regulatory framework that …

Beyond The Prompt: The Social Costs Of Generative Artificial Intelligence, J. Scott Christianson, Josh Rickard

The Business, Entrepreneurship & Tax Law Review

This Article provides a review of these externalities across three domains: environmental, human health, and digital infrastructure. The environmental burden includes massive energy and water consumption alongside ecologically destructive mining for rare earth elements and accelerating electronic waste. The human toll encompasses a documented pattern of AI-induced mental health crises, including suicide and self-harm linked to anthropomorphic chatbot design, raising novel questions of product liability in cases like Garcia v. Character.AI. The digital commons face degradation through industrialized data scraping …

Handling Item-Level Missing Data In Linear Regression: A Tutorial, Guyin Zhang, Lihan Chen, Dexin Shen

Faculty Publications

With advances in methodology and statistical software, modern methods for handling missing data have become more accessible and straightforward to apply. In psychological studies, researchers often use questionnaires or scales composed of multiple items to measure constructs of interest. As a result, missing values frequently occur at the item level, whereas data analyses are typically conducted at the scale (composite) level. However, properly addressing item-level missing data remains a common challenge for many applied psychologists, including researchers who are otherwise well experienced in handling missing data at the scale level. In this tutorial, we introduce six approaches for handling item-level …

All Faculty Scholarship

Objectives: The aim of the study was to evaluate the effect of mindfulness exercises on stress management and resilience among ELMSN students. Methods: The study was a quasi-experimental design that used a paired samples t-test to compare pre-test and post-test of students’ scores on both GAD-7 anxiety screening tool and short version of Grit-scale. Statistical tests were conducted with significance set at p < 0.05 (two-sided). All analyses were performed using IBM SPSS Statistics, version 31.0 to compare pre-/post-test scores, determine differences, and statistical significance of interventions among the cohort. And a priori power analysis was conducted to determine the required sample size for a paired samples t-test. With an alpha level of 0.05 and a medium effect size (Cohen’s d = 0.50), a total sample size of N = 34 was determined to be sufficient to achieve a power of 0.80. Results: A convenience sample of 40 students (35 females and 5 males) participated in the study. Students had more anxiety before mindfulness exercises (M = 7.00, SD = 5.5) compared to after the mindfulness exercises (M = 6.2, SD = 3.4), t(39) = 1.41, p = 0.17. The effect size was small, d = 0.22. However, the difference in the students’ anxiety levels after the mindfulness exercises was not statistically significant, with a p-value of 0.17. On the resilience, students were less resilient before mindfulness exercises (M = 3.58, SD …
