Computer Self-Efficacy As Predictor Of Electronic Information Resources Use By Academic Staff Of Selected Polytechnics In South-West, Nigeria., Temitope Adeleke Osisanwo Dr, Yemisi Tomisin Babalola Prof

Library Philosophy and Practice (e-journal)

Electronic information resources have become a significant portion of library resources available to academic staff for teaching and research purposes. However, studies suggest that their use has not been fully optimized by academic staff at polytechnics located within South-West, Nigeria. This could be attributed to the low level of self-effectiveness of technology among the academic staffs. In light of this, this study aimed to examine the relationship between computer self-efficacy and the usage of electronic information resources among polytechnics academic staff in South-West, Nigeria.

A survey research design was used for this study, while 3,807 academic staff members were selected …

Identification Of Inhibitors Of An N- Monooxygenase From Aspergillus Fumigatus, Kendra B. Bufkin, Pablo Sobrado

Arts, Languages and Philosophy Faculty Research & Creative Works

The flavin-dependent N-monooxygenase SidA from Aspergillus fumigatus catalyzes the conversion of l -ornithine to N⁵-hydroxy- l -ornithine. This product is incorporated into hydroxamate containing siderophores, which are iron chelators required for growth during A. fumigatus infection in mammals. The activity of SidA has been shown to be required for siderophore biosynthesis. Here, we used a colorimetric product formation assay to screen a small-molecule library for the identification of potential inhibitors of SidA. Ebselen, an organoselenium compound, was identified as an inhibitor of SidA. This compound inhibited SidA with an IC50 value of 11 ± 1 μM. Ebselen derivative, …

Children’s Nutrition Research Center Staff Publications

Background and aims: Gambling disorder (GD) has been linked to suicidal ideation and suicide deaths; however, evidence on all-cause and cause-specific mortality-particularly in Asian populations-remains limited. Using a retrospective cohort study based on nationwide matched and sibling cohort, we investigated all-cause and cause-specific mortality risk in patients with GD.

Design, setting and participants: A retrospective cohort study was conducted using 2000-2022 data from Taiwan's National Health Insurance Research Database. A cohort of 961 individuals diagnosed with GD was identified. An age- and sex-matched control cohort (n = 3,844) and an unaffected sibling cohort (n = 675) were constructed. Cumulative survival …

Hyperadhesive Von Willebrand Factor Contributes To Pathogenesis Of Preeclampsia, Yajuan Wang, Chenyu Wang, Katie L Houck, Xiaoli Gao, Yuanyuan Chen, Xin Xu, Xue Zhao, Miguel A Cruz, Shu Zhang, Chester Q Li, Fengxia Xue, Min Li, Swati Shree, Jing-Fei Dong, Cha Han

Children’s Nutrition Research Center Staff Publications

Background: Preeclampsia is the most common complication of pregnancy, significantly affecting maternal and fetal health, and is characterized by placental and systemic endotheliopathy. Patients with preeclampsia have elevated levels of VWF (von Willebrand Factor), which is associated with poor clinical outcomes. However, whether VWF serves as a marker for endotheliopathy or contributes to the pathogenesis of preeclampsia remains poorly understood.

Methods: We investigated the role of hyperadhesive VWF in the development of preeclampsia by studying patients, evaluating mouse models, and performing in vitro experiments.

Results: We show that patients develop VWF- and fibrin-rich thrombosis in the placenta and have significantly …

Socially-Minded Investors And Corporate Behavior, Merritt B. Fox, Menesh S. Patel

Faculty Scholarship

Many equity investors are concerned with the world’s worsening social and environmental problems and are losing faith in the capacity of political institutions to respond. Corporate behavior is often contributing to these problems. Some investors, at least if fully informed as to costs and benefits involved, would favor corrective changes to corporate behavior even where that would lessen their investment returns. Two important questions arise: (1) given existing law, are such willing-to-sacrifice equity investors currently affecting firm behavior; and (2) should there be legal reform that makes firms more sensitive to these willing-to-sacrifice investors’ preferences? This Article seeks to answer …

Genetic Regulation Of Uterine Organogenesis, Diana A. Machado

Dissertations and Theses (Open Access)

In eutherian and marsupial mammals, the site of embryo implantation and gestation is the uterus. The precursor tissue of the uterus, oviducts, cervix, and upper vagina is the Müllerian duct epithelium and its adjacent mesenchyme. Morphological uterine variation between species is established during embryogenesis by species-specific differences in Müllerian duct fusion at the midline, growth, and differentiation. For example, laboratory mice have a bipartite uterus with two uterine horns and a single cervix, whereas humans have a simplex uterus with a single chamber and single cervix. In humans, variations in the fusion process can alter typical uterine morphology, correlating with …

Reduced Lower Extremity Strength, Altered Muscle Activation, And Unchanged Kinetics During Single-Leg Squatting In Males With Patellofemoral Pain Versus Pain-Free Males: A Cross-Sectional Analysis, Lisa T. Hoglund, Amy H. Amabile, Thomas Alexander Hulcher, Victoria K. Polansky, Erin L. Dopke

Department of Physical Therapy Faculty Papers

BACKGROUND: Patellofemoral pain is frequently a cause of reduced quality of life in physically active males. The cause of patellofemoral pain is theorized to include aberrant biomechanics during weight-bearing activities. Altered biomechanics of females with patellofemoral pain have been reported, but there is a dearth of research for males with this condition. This study aimed to compare males with and without patellofemoral pain for hip and knee joint moments and muscle activation during single-leg-squatting and proximal muscle strength.

METHODS: Twenty males with patellofemoral pain and 20 pain-free males aged 20-39 years performed single-leg-squatting while motion, ground reaction force, and proximal …

Kimmel Cancer Center Faculty Papers

BACKGROUND: Many older adults with cancer have at least one comorbidity. Type II diabetes mellitus (T2DM) is a common comorbidity among patients with prostate cancer (PC) and represents an important consideration in this population. Comorbid T2DM can negatively impact cancer-specific outcomes for patients, suggesting the need for better glycemic management, especially for patients on active cancer treatment. The goal of this modified Diabetes Self-Management Education Services (mDSMES) pilot study was to provide patients with the opportunity to learn methods of diabetes self-management, including how to manage their glucose levels, improve their understanding and utilization of medication to promote improvements in …

Paleolimnology And Diatom Taxonomy From Lake Tanganyika, Sristika Adhikari

All-Inclusive List of Electronic Theses and Dissertations

Lake Tanganyika is one of the world's largest freshwater ecosystems, supporting rich aquatic biodiversity and providing several ecosystem services to surrounding communities. Environmental changes such as rising lake surface temperatures, pollution, and land-use alterations threaten the lake’s sustainability. This research examines spatial and temporal variations in nutrient dynamics and primary productivity of Lake Tanganyika using diatom assemblages from multiple locations. Our findings indicate reduced nutrient levels and longer stratification periods in the lake’s central basin during most of the Common Era, as indicated by a remarkable increase in the relative abundance of long, needle-shaped planktonic Nitzschia species. In the southern …

Quraishi, Preston Carey, Arbaz A. Momin, Matthews Lan, Dwight Mitchell Self, Ashmal S. Kabani, Ahilan Sivaganesan

Department of Neurosurgery Faculty Papers

BACKGROUND: Despite wide variation in the outcomes and costs of lumbar fusion, few studies have integrated these domains together within a single metric to assess "value" (outcomes achieved per dollar spent). In this review, we sought to 1) characterize existing metrics of cost-effectiveness for lumbar fusion, 2) evaluate all applications of time-driven activity-based costing (TDABC) in spine surgery, and 3) outline the conceptual foundation for a standardized Operative Value Index (OVI).

METHODS: Two PRISMA-concordant systematic reviews were performed on PubMed and Scopus databases. The first review examined all studies which reported a cost-effectiveness metric for lumbar fusion. The second review …

Staff Education On The Implementation Of An Evidence-Based, Suicide-Risk-Assessment Education Program For Psychiatric Staff, Yemurai Emily Dzikiti

Walden Dissertations and Doctoral Studies

Suicide is a major public health concern, and consistent suicide risk assessment is essential for patient safety in psychiatric settings. This Doctor of Nursing Practice staff education project addressed a knowledge gap in evidence-based suicide risk assessment among psychiatric clinicians in an outpatient mental health setting. The practice-focused question examined whether an evidence-based suicide risk assessment education program would improve clinicians' knowledge from pre- to post-education. The educational intervention consisted of a 60-minute in-person training session on evidence-based suicide risk assessment using the Columbia-Suicide Severity Rating Scale (C-SSRS) and the Suicide Assessment Five-Step Evaluation and Triage (SAFE-T) framework. Ten psychiatric …

Fibrous Protein Biomaterials: Characterization Of Solitary Bee Silk And Cocoons, And Development Of Recombinant Hagfish And Bee Silk Materials, Oran Wasserman

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation explores two complementary aspects of fibrous protein biomaterials: the characterization of understudied naturally occurring solitary bee silk and cocoons; and recombinant expression and biomaterial formation of recombinant hagfish intermediate filaments (rHIF) and a single Osmia lignaria Say (Hymenoptera: Megachilidae) silk protein. Some solitary bee species, which make up about 75% of all bee species, spin silk to construct protective cocoons during development. Despite the importance of silk and cocoons to the solitary bees' life history, their properties remain largely unexplored. This dissertation presents a novel method for isolating and testing individual silk fibers without interfering with the development …

Visualizing The Phase Space Of Two Interacting Spherical Magnets Via Lagrangian Descriptors, Matthew Pontius

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis studies the motion of one spherical magnet sliding on another fixed spherical magnet. Although the setup is simple, the resulting motion can range from regular and predictable to chaotic as the energy increases. To understand this behavior, mathematical tools are used to visualize how all possible motions are organized in phase space. These methods reveal patterns such as stable regions, repeating motions, and chaotic trajectories. The results show how order and chaos coexist in this system and provide insight into how small changes in the initial conditions can lead to very different outcomes.

Comparing Error Correction Strategies In Discrete Trial Training For Children With Autism, Rachael Litchford

All Graduate Theses and Dissertations, Fall 2023 to Present

Children diagnosed with Autism Spectrum Disorder (ASD) often require structured, evidence-based teaching methods to promote skill acquisition. Discrete Trial Training (DTT) is one such approach widely used in Applied Behavior Analysis (ABA) to teach skills through repeated learning opportunities. However, limited research has compared the efficiency of specific error correction procedures within DTT. This study examined the comparative effectiveness of two error correction strategies, Active Student Response (ASR) and Model-Only, when acquiring tacting skills for children ages 2-10 with ASD. An alternating treatments design (ATD) was used to evaluate each strategy’s impact on skill acquisition, as measured by the percentage …

Investigating Recruitment Bottlenecks Of Juvenile Native Fish In The Colorado River Basin, Utah, Anna R. Amidon

All Graduate Theses and Dissertations, Fall 2023 to Present

The first year of life is a vulnerable period for most fish species. Whether young fish survive this early stage determines how many individuals eventually survive and grow into reproductive adults, a process called recruitment. In desert rivers like the Colorado River Basin, native fish evolved alongside extreme natural conditions but now face additional pressure from drought and water storage infrastructure, which alter the shoreline habitats on which young fish depend. Long-lived, migratory native species with complex life cycles are especially vulnerable. We used four decades of monitoring data from the Upper Colorado River Basin to evaluate whether young-of-year (YOY, …

Cultural Humility In Motion: A Graduate Student Hybrid Immersion In Self- And Other Awareness Through Dance, Emily Jeanne Slater

All Graduate Theses and Dissertations, Fall 2023 to Present

Universities bring together people from many different backgrounds, identities, and experiences. Yet university spaces often focus on mind-centered and discussion-based learning and overlook how the body plays a role in education. When education ignores the bodily experience of learning, students lose opportunities to reflect, connect, and make meaningful change in their lives and communities. To address this gap, this dissertation designed and implemented a learning experience for graduate students that creates space from them to examine their own assumptions, engage across differences, and share in inclusive practices. The learning experience draws on and advances cultural humility theory, which understands self-awareness, …

Issue 26: Labour, Poverty, And Health Concerns Of Migrant Women And Girls Working As Kayayei In Ghana's Urban Centres, Comfort Baidoo, Robert Mcleman

International Migration Research Centre

Over the past four decades, growing numbers of women and girls have left northern Ghana for the country's cities, drawn by the promise of work, independence, and a chance to support their families. Many end up as kayayei, head porters who carry goods through Accra's crowded markets for a negotiated fee. Their labour keeps the informal economy moving, yet it comes at a steep personal cost: unpredictable earnings, punishing physical strain, unsafe housing, and a healthcare system that too often leaves them out. This brief draws together the available evidence on the economic and health conditions of kayayei in Greater-Accra. …

Content Mapping: An Experimental Analysis Of Missing Message Content, Jeannette Sutton

Emergency Preparedness, Homeland Security, and Cybersecurity Faculty Scholarship

The Warning-Response Model recommends the inclusion of five key content areas in warning messages to reduce information seeking that can lead to warning response delay: the message source, hazard (including its impact), affected location, recommended guidance, and time. Research has found that complete messages, that is, those that include all of five recommended content areas, help people make decisions about the protective actions they may take.  Unfortunately, a large majority of WEA messages omit information from one or more of the recommended content areas. This study examined the impact of omitting each of the five recommended content areas on message …

Human-Centered Electric Vehicle Adoption Framework For Smart Mobility: Modeling Perceived Range And Charging Anxiety As A Psychological Barrier, Fatemeh Nazari, Abolfazl (Kouros) Mohammadian, Thomas Stephens

Civil Engineering Faculty Publications

Electric vehicles (EVs) offer a transformative pathway toward reducing the environmental, economic, and health-related externalities of internal combustion engine vehicles in urban settings. Despite substantial advances in battery technology, charging infrastructure expansion, and supportive policy incentives, EV penetration remains limited which poses challenges for smart and sustainable mobility planning. A critical yet insufficiently modeled barrier to adoption lies in the psychological perceptions surrounding electric driving range and charging reliability, which is commonly framed as “range anxiety,” but more broadly reflecting perceived range and charging anxiety. To address this gap, this study introduces a latent psychological construct capturing individuals’ perceived range …

A Novel Edge-Based Accuracy Assessment Framework For Target Detection From Remotely Sensed Images, Yingfan Zhang, Weiyi Hou, Lyndon Estes, Rui Lu, Shijie Zhu, Aiyin Zhang, Zhou Shi, Su Ye

Geography

Accuracy assessment is critical for evaluating map quality and improving algorithms for target detection in remotely sensed images. Traditional methods for assessing a target-detection task were often performed by estimating the relative pixels of correct and incorrect identifications (e.g., F1 score). However, this approach only considers the pixel-by-pixel agreement and ignores important aspects of positional errors and target object quality. To provide comprehensive diagnostic information, we propose a novel edge-based accuracy assessment framework. This framework firstly applied a newly proposed assessment tool, Dynamic Epsilon-band Accuracy Function (DEAF), which is a linear fitting function from a series of edge accuracies associated …

Llm-Based Early Rumor Detection With Imitation Agent, Fengzhu Zeng, Qian Shao, Ling Cheng, Wei Gao, Shih-Fen Cheng, Jing Ma, Cheng Niu

Research Collection School Of Computing and Information Systems

Early Rumor Detection (EARD) aims to identify the earliest point at which a claim can be accurately classified based on a sequence of social media posts. This is especially challenging in data-scarce settings. While Large Language Models (LLMs) perform well in few-shot NLP tasks, they are not well-suited for time-series data and are computationally expensive for both training and inference. In this work, we propose a novel EARD framework that combines an autonomous agent and an LLM-based detection model, where the agent acts as a reliable decision-maker for \textit{early time point determination}, while the LLM serves as a powerful \textit{rumor …

A Deep Reinforcement Learning Framework For Dynamic Order And Rack Scheduling In Robotic Mobile Fulfillment Systems, Lingjun Wang, Bayi Cheng, Zhiguang Cao, Aldy Gunawan

Research Collection School Of Computing and Information Systems

Robotic mobile fulfillment systems play a vital role in modern e-commerce, but their efficiencydepends on overcoming a critical challenge: coordinating orders and racks effectively under dynamicorder arrivals, diverse delivery deadlines, and resource sharing among multiple stations. This papertackles the resulting dynamic order and rack scheduling problem and proposes an intelligentscheduling framework centred on deep reinforcement learning. At its core is TriNet-PPO, whichtrains a scheduling policy using TriNet, a tripartite graph neural network encoder tailored to capturethe many-to-many relationships among orders, racks, and items. Furthermore, we introduce IPCSA,an integer programming-based cooperative scheduling algorithm that maps station-level actionpreferences to conflict-free joint decisions …

Bank Competition Amid Digital Disruption: Implications For Financial Inclusion, Erica Xuewei Jiang, Gloria Yang Yu, Jinyuan Zhang

Research Collection Lee Kong Chian School Of Business

We examine how digital disruption affects bank competition using the staggered rollout of 3G mobile networks. 3G expansion increased mobile banking adoption among tech-savvy households, reducing branch networks—especially in younger counties. Banks' strategies diverged: Less branch-reliant banks closed branches and competed on price, while more branch-reliant banks maintained branches but raised spreads. A structural model shows that perceived digital service improvements among younger consumers drove these shifts, reducing welfare for older savers. Counterfactuals demonstrate that subsidizing adoption for older savers can cost-effectively reduce these disparities, facilitating a smoother digital transition.

Optimal Scheduling Of Virtual Power Plants Considering Photothermal Power Stations And Hydrogen Energy Utilization, Yousong Chen, Ruofa Cheng, Yi Liu, Yi Zhang, Zhihao Zuo

Journal of System Simulation

Abstract: To enhance the operational stability and low-carbon performance of virtual power plants (VPPs) with high shares of renewable energy, a coordinated dispatch model integrating concentrated solar power (CSP) plants with power-to-gas (P2G) and carbon capture is developed. An optimal VPP scheduling strategy is proposed, combining a stepped carbon trading mechanism with a compensation coefficient and dynamic hydrogen blending. To address multi-source uncertainties in wind power, CSP power, and loads, an envelope boundary model is used for simulation. Information gap decision theory (IGDT) is applied to provide customized solutions for decision-makers with different risk preferences. A bi-objective optimization model is …

Fault-Tolerant Control Method For All-Type Actuator Faults Of Evtol Aircraft, Juan Wang, Guorui Li, Zhiyong Fan, Huijie Chen

Journal of System Simulation

Abstract: To address all-type actuator faults, especially nonlinear distortion issues, in multi-rotor eVTOL aircraft, a novel fault-tolerant control method was proposed. A fault function was established at the rotor speed level, and a fault-tolerant control algorithm combining dynamic robust nonsingular fast integral terminal sliding mode with a high-order finite-time disturbance observer was designed to achieve fault-tolerant control through rotor redundancy allocation. The nonsingular fast integral terminal sliding mode algorithm was improved, and a dynamic system containing actuator faults and their derivatives was constructed via a dynamic surface to achieve system convergence within finite time, avoiding the singularity and chattering problems …
