Research Collection School Of Computing and Information Systems

Tactile graphics on a refreshable display have proven effective in enabling visually impaired people to comprehend pictorial content. To further evaluate the effectiveness of refreshable tactile displays in blind education, we designed tactile data comics, a method that combines step-by-step presentation of tactile graphics with verbal narration. We conducted a user study with sixteen visually impaired students to compare tactile data comics against verbal-only and static tactile graphics. Our findings show that tactile data comics significantly improve participants’ comprehension and engagement during the learning experience. These empirical results suggest that the integration of refreshable tactile displays and tactile data comics …

Staff Matters: Maintaining Empathy And Respect When Performance Issues Occur, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

In her monthly column, human resource expert Jodi Schafer provides guidance on managing employee performance issues and terminations with empathy and respect. She highlights that a practice's reputation is influenced by how it treats people, especially during difficult moments. Strategies include early intervention—documenting specific incidents and giving timely feedback instead of waiting until frustration builds. Leaders should foster open dialogue to offer support, such as training refreshers, before resorting to discipline. Difficult conversations should be held in private with honesty and compassion. If termination is necessary, leaders should "exit with grace," clearly explaining final steps and making a neutral announcement …

Volumetric Differences Of Thalamic Nuclei Are Associated With Posttrauma Psychopathology, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Background

Previous investigations of whole thalamus and thalamic nuclei volumes in posttrauma psychopathology have been sparse and limited in scope and have yielded inconsistent results. To address this, volumetric estimates of whole thalamus and thalamic nuclei were obtained from structural brain magnetic resonance imaging scans from 2058 participants across 20 worldwide sites in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Posttraumatic Stress Disorder (PTSD) working group.

Methods

Thalamic volumes were compared in trauma-exposed participants with PTSD (n = 238), major depressive disorder (MDD) (n = 184), and comorbid PTSD+MDD (n = 618) and in trauma-exposed …

Fcad: Feature-Coupled Anisotropic Diffusion For Continuous Graph Learning, Amitoz Azad, Zhiyuan Zhang

Research Collection School Of Computing and Information Systems

In this work, we propose a novel continuous graph neural network called FCAD (Feature-Coupled Anisotropic Diffusion) for the task of node classification on graphs. Our approach is motivated by the success of feature-coupled anisotropic diffusion PDEs in multivalued image restoration. Our method introduces a total variation regularization-inspired anisotropic term to control diffusion between nodes and incorporates a learnable parameterization for feature coupling during the diffusion process. Our model performs competitively against several GNN baselines for both heterophilous and homophilous graphs, demonstrating notable benefits for heterophilous graphs due to the learnable feature coupling.

Diffusionmat: Alpha Matting As Deterministic Sequential Refinement Learning, Yangyang Xu, Shengfeng He, Wenqi Shao, Yong Du, Kwan-Yee K. Wong, Yu Qiao, Jun Yu, Ping Luo

Research Collection School Of Computing and Information Systems

In this paper, we introduce DiffusionMat, a novel image matting framework that employs a diffusion model for the transition from coarse to refined alpha mattes. Diverging from conventional methods that utilize trimaps merely as loose guidance for alpha matte prediction, our approach treats image matting as a deterministic sequential refinement learning process. This process begins with the addition of noise to trimaps and iteratively denoises them using a pre-trained diffusion model, which incrementally guides the prediction towards a clean alpha matte. The key innovation of our framework is a correction module that adjusts the output at each denoising step, ensuring …

Using Some Artificial Intelligence Algorithms To Estimate The Parametric Regression Function For Spatially Dependent Data Of Water Pollution Of The Euphrates River, Ons Edin Musa, Sabah Manfi Redha

Journal of Economics and Administrative Sciences

These models account for the spatial effects resulting from the proximity of events. A compromise exists in the mathematical accuracy of model parameters when spatial correlations are present in the data of the phenomenon. Data reliant on spatial correlations are crucial in statistical modelling, especially in environmental science, economics, epidemiology, and various other disciplines. This study employs and compares three artificial intelligence approaches—the genetic algorithm (GA), the TABU search algorithm (TSA), and the binary firefly algorithm (Binary FFA)—to determine which is the most efficient for estimating the parametric regression function for spatially dependent data.

Everyday Norms Have Become More Permissive Over Time And Vary Across Cultures, K. Eriksson, P. Strimling, I. Vartanova, Andree Hartanto

Research Collection School of Social Sciences

Every social situation that people encounter in their daily lives comes with a set of unwritten rules about what behavior is considered appropriate or inappropriate. These everyday norms can vary across societies: some societies may have more permissive norms in general or for certain behaviors, or for certain behaviors in specific situations. In a preregistered survey of 25,422 participants across 90 societies, we map societal differences in 150 everyday norms and show that they can be explained by how societies prioritize individualizing moral foundations such as care and liberty versus binding moral foundations such as purity. Specifically, societies with more …

False Friends: The Pereiaslav Agreement Of 1654 And Competing Narratives In Russian And Ukrainian Historiographies, Jiansheng Zhang

Armstrong Undergraduate Journal of History

The Pereiaslav Agreement of 1654, concluded between the Cossack Hetmanate and the Grand Duchy of Muscovy at the Pereiaslav Rada, marked the beginning of modern Cossack-Muscovite (in perspective, Ukrainian-Russian) relations. Owing to its central role in shaping both Russian and Ukrainian national narratives, the agreement remains a highly contentious event in Eastern European history. Historians from the Russian and Ukrainian historiographical traditions offer divergent interpretations of how the agreement was conceived and received by the Cossacks and Muscovites. Drawing on a wide range of primary and secondary sources, this essay critically examines these competing narratives and concludes that Ukrainian historiography—emphasizing …

Through His Eyes: The Life Of American Pows In Germany And Ben Phelper’S Diary, Bianca Shah

Armstrong Undergraduate Journal of History

This paper aims to examine the treatment American prisoners of war experienced at the hands of their German captors during World War II. Ben Phelper, a US Airman who was taken captive by the Germans from 1943-1945, wrote a diary detailing his daily life while living in the stalags. This research uses Phelper’s diary to understand what life was like for Americans in German POW camps and compares Phelper’s experience to existing literature on how Germans treated their American POWs. This paper specifically focuses on four aspects of Phelper’s life in relation to the provisions of the Geneva Convention, the …

From Nociception In Aneural Animals To Human Suffering: Toward A Comparative Biology Of Pain, Edgar T Walters

Faculty, Staff and Student Publications

Pain is a core feature of human life, but systematic comparisons of this biological trait across taxa have been rare. A broadly accepted definition based on human experience emphasizes dual features of pain: a sensory (discriminative) component for sensing and monitoring tissue injury, and an affective (emotional) component to motivate avoidance of tissue distress. Conscious pain is coupled to unconscious nociception (detection of incipient or existing injury). This Review considers nociception and pain across phyla within a comparative framework, addressing basic questions about evolutionary origins, mechanisms and functions of pain. The occurrence of adaptive cellular responses to injury in virtually …

2020-Current year OA Pubs

Cerebral glucose metabolism (CMRGlc) systematically decreases with advancing age. We sought to identify correlates of decreased CMRGlc in the spectral properties of fMRI signals imaged in the task-free state. Lifespan resting-state fMRI data acquired in 455 healthy adults (ages 18-87 years) and cerebral metabolic data acquired in a separate cohort of 94 healthy adults (ages 25-45 years, 65-85 years) were analyzed. The spectral properties of the fMRI data were characterized in terms of the relative predominance of slow versus fast activity using the spectral slope (SS) measure. We found that the relative proportion of fast activity increases with advancing age …

Better Digital Contracts With Prosocial Friction-In-Design, Brett Frischmann, Moshe Y. Vardi

Faculty Publications

Contract law is supposed to enable people to reach genuine agreements and cooperate. If this ideal was ever a reality, the rise of mass market contracts and boil­erplate rendered it pure fiction. Modern consumer contracts are incomprehensible to most people. No one reads them anyway.

Digital contracting involves design features that amplify traditional boilerplate harms and create others. For example, digital contracting is too cheap; low marginal costs lead to overexpansion in scale and scope. To make matters worse, the loss of autonomy from repeat engagement with digital contracting systems is pernicious. People become increasingly predictable and programmable as digital …

Succinate Dehydrogenase B (Sdhb) Overexpression With Enzymatic Dysfunction Defines A Distinct Subtype Of Undifferentiated Pleomorphic Sarcoma, Miguel Esperança-Martins, Brian A Van Tine, Alliny C S Bastos, Et Al.

2020-Current year OA Pubs

UNLABELLED: Undifferentiated pleomorphic sarcoma (UPS) remains one of the most clinically aggressive and poorly characterized soft-tissue sarcoma subtypes. To uncover distinctive molecular traits for UPS, a multiomics analysis of UPS compared with leiomyosarcoma (LMS) and liposarcoma (LPS) was performed. Transcriptomic profiling revealed that UPS exhibits overexpression of genes encoding succinate dehydrogenase (SDH) subunits, particularly SDHB, SDHC, and SDHD, distinguishing it from LMS and dedifferentiated LPS. This finding was validated using The Cancer Genome Atlas Sarcoma dataset. High SDHB expression in UPS was significantly associated with shorter overall survival, shorter recurrence-free survival, and shorter overall survival from the date of first …

Hooks For Four-Dimensional Ecology Education (4dee) Teaching With Differing Audiences Of Nonmajors, Sara E. Scanga, Vikki L. Rodgers, Loren B. Byrne, Justin R. St. Juliana, Jon M. Honea, Erica S. Tietjen, George Middendorf

Arts & Sciences Faculty Publications

Nonmajors (i.e., undergraduate students not majoring in the natural sciences) constitute a majority of United States college graduates and are a large potential audience for courses with ecology content. However, nonmajors may be unmotivated to learn about ecology because they perceive it to be uninteresting and irrelevant to their everyday lives or career goals. Although the Four-Dimensional Ecology Education (4DEE) framework can be adapted for nonmajors courses as a starting point to improve student engagement, we suggest that nonmajors ecology instructors also use ecology hooks as effective gateways to 4DEE that will motivate and deepen student learning. Selecting and developing …

Faculty, Staff and Student Publications

Background: Callous-unemotional (CU) traits during adolescence, for example, shallow affect or lack of remorse, have been shown to be a risk marker for antisocial behavior. Only a few studies have investigated structural brain alterations underlying CU traits, and findings are inconclusive. The study examines CU symptomatology and gray matter volume (GMV) associations.

Methods: Structural brain MRI data were collected from a sample of 578 adolescents (60% male) with a mean age of 14.85 years (SD = 2.30; range = 10-19 years). CU traits were indexed via the Inventory for Callous Unemotional Traits (ICU). Region-wise volumetric parameters were obtained following parcellation …

Perioperative Antibiotic Administration Review: An Analysis Of Outpatient Surgeries At Ohiohealth Doctors Hospital., Rayyan Bhutta, Thomas Shneker, Samantha Currier, Alexander Caskey, Vincent Relli-Dempsey, Matthias Franzen, Samir Patel

Surgery Articles

INTRODUCTION: A vital part of preventing surgical site infections (SSIs) is perioperative antibiotic prophylaxis. Antibiotics must be administered within a certain window of time, usually 15 to 60 minutes prior to the surgical incision, for them to be effective. The most frequently utilized medication, cefazolin, can be administered quickly by intravenous push (IVP), but other medications, such as vancomycin and clindamycin, need longer infusion times. Antibiotic efficacy declines, and the risk of SSIs is increased when scheduling requirements are not followed. With special focus on time, dosage, and variation by surgery type, this study evaluates adherence to perioperative antibiotic administration …

Defining strategy at the cabinet level and ensuring its implementation at the operational level, the National Security Advisor must act as an honest broker of the inter-agency process. This article will examine the role of three National Security Advisors from the Nixon, Carter and George W. Bush administrations, and study two examples of operational success and failure, highlighting the importance of the strategic-operational link. The author concludes by recommending a National Security Council (NSC)-led inter-agency framework that drives consensus-based strategic planning and mandates operational coordination through …

Intelligence As An Instrument Of National Power: Lessons Learned From The Tensions Between Serbia And Kosovo, Vadym Chernysh

Journal of Strategic Security

Intelligence activity is unique; it can be a valuable and powerful tool in the hands of state leaders. Leaders should rely not solely on their perception or intuition to leverage the intelligence instrument of national power but rather on understanding this phenomenon and its inherent qualities. Often, political leadership may confuse the functions of intelligence and law-enforcement agencies, leading to the ineffective or inefficient use of national power instruments to achieve strategic goals. Leveraging the intelligence instrument of national power in prolonged conflicts with a larger adversary is a crucial aspect of statecraft. The role of intelligence can be vital …

The Institutional Effect: Democracies, Dictators And Diversionary Foreign Policy, Thomas Reilly

Journal of Strategic Security

The diversionary theory of war remains controversial in International Relations. The extant literature remains dominated by the study of democratic diversions and the use of warfare as the prime diversionary strategy. The sheer amount of work covering democratic diversions has created theoretical biases which are oft transposed to autocratic states, despite being largely unique to democratic processes. This article expands the traditional bounds of diversionary theory to provide a logic of autocratic diversions and diversionary strategies outside of war, presenting a theoretical framework which argues that institutionalization is the primary conduit through which the intended audience, benefit and preferred diversions …
