Mesopotamian Journal of Artificial Intelligence in Healthcare

As healthcare becomes increasingly dependent on the Internet of Medical Things (IoMT) infrastructure, it is essential to establish a secure system that guarantees the confidentiality and privacy of patient data. This system must also facilitate the secure sharing of healthcare information with other parties within the healthcare ecosystem. However, this increased connectivity also introduces cybersecurity attacks and vulnerabilities. This comprehensive review explores the state-of-the-art in the IoMT, security requirements in the IoMT, cryptographic techniques in the IoMT, application of cryptographic techniques in securing the IoMT, security attacks on cryptographic techniques, mitigation strategies, and future research directions. The study adopts a …

Cross-Temporal Hierarchical Forecast Reconciliation Of Natural Gas Demand, Colin O. Quinn, George F. Corliss, Richard J. Povinelli

Electrical and Computer Engineering Faculty Research and Publications

Local natural gas distribution companies (LDCs) require accurate demand forecasts across various time periods, geographic regions, and customer class hierarchies. Achieving coherent forecasts across these hierarchies is challenging but crucial for optimal decision making, resource allocation, and operational efficiency. This work introduces a method that structures the gas distribution system into cross-temporal hierarchies to produce accurate and coherent forecasts. We apply our method to a case study involving three operational regions, forecasting at different geographical levels and analyzing both hourly and daily frequencies. Trained on five years of data and tested on one year, our model achieves a 10% reduction …

The Effectiveness Of Motor-Motor And Motor-Cognitive Dual-Task Training Interventions On Balance In People With Parkinson’S Disease: Rct Design, Feasibility, And Acceptability Testing, Nesibe Cakmak

School of Health Professions Theses

Background: Dual-task training (DTT), utilized in motor-motor (M-DTT) and/or cognitive-motor (C-DTT) forms, has been identified as an effective and safe approach to improve balance in people with Parkinson’s disease (pwPD). Studies which investigate the superiority of the effectiveness of M-DTT and CDTT interventions, however, are lacking. To determine superiority there is a need to design a randomized control trial (RCT). This PhD study, therefore, had two aims. Firstly, to design home-based M-DTT and C-DTT interventions for improving upright balance in people with mild to moderate PD. Secondly to test the feasibility and acceptability of the interventions, outcome measures, and the …

While much of the focusof research is on the use of Generative AI in and for education,AI as a core subject area is still gaining popularity, with much ofthis research focusing on content and tools that effectively support the teaching of AI. However, as we grow as a field, there isa need currently unmet to provide foundations (in the form of ablock model as there exists for programming) to allow researchersto build strong pedagogies and methodologies from, and even abase to design activities and content. Compounding this, …

On Design Load Prediction And Extreme Response Modelling Of Floating Offshore Renewable Energy Structures, Tom Tosdevin

School of Engineering, Computing and Mathematics Theses

FLOATING offshore renewable energy (FORE) is a marginal industry and as such cost reductions are essential in order for it to become competitive with other forms of electricity generation. Design practices for evaluating the extreme responses of FORE devices are still under consideration by standards authorities, thus methods that enable potential speeding up of the design and development phases, particularly physical model testing are needed. Probabilistic design approaches have proved effective in bringing down costs in the aerospace and automobile industries and so provide a potential route to viability by allowing partial safety factors to be reduced. However, the scarcity …

Do Audit Partners Exhibit Hometown Bias?, Yuzhou Chen, Timothy Seidel, Aleksandra "Ally" B. Zimmerman

Faculty Publications

We investigate whether audit partners exhibit greater leniency towards audit clients located in their childhood or pre-professional home state. While prior research has examined the audit quality effects of geographic distance between an auditor and client as well as auditors’ social ties to company management or directors, this study uniquely examines auditors’ psychological affinity to places rather than people. Using hand-collected data on audit partners, company managers, and directors, we find evidence of partners exhibiting hometown bias in the form of greater leniency towards clients’ opportunistic reporting. However, we find no evidence to suggest that these psychological biases affect audit …

Strategic Alignment, Performance, And The Moderating Effect Of Regulatory Fit, Hayden T. Gunnell, Steven D. Smith, Travis W. Steadman

Faculty Publications

We examine how the alignment of performance measurement and strategy affects performance on a multidimensional task. Our experiment varies both the strategy (speed versus accuracy) of the hypothetical firm for which participants work and the individual performance measure that is reported to them, creating two conditions of clear alignment and two of clear misalignment. We find that while workers are responsive to the performance measure regardless of its alignment, they are also sensitive to the strategy such that costly alignment effects are observed. We also predict and find that workers respond asymmetrically to misalignment in accuracy performance but not in …

The Effects Of Strategic Alignment And Strategic Clarity On Multidimensional Task Performance, Steven D. Smith, Tyler F. Thomas

Faculty Publications

The alignment of a firm’s performance measures with its strategic objectives is fundamental to effective management control, at least in part because performance measures and stated strategy represent separate sources of information that workers can rely on to guide their efforts. We experimentally examine the effects of strategic alignment and strategic clarity (i.e., the specificity with which strategic objectives are communicated) on workers’ performance on a multidimensional task. We predict and find that alignment improves performance under a vague strategy statement but impairs performance under a clear strategy statement. These results are consistent with strategic clarity and performance measure alignment …

Structure-Function Relationship Of Oat Flour Fractions When Blended With Wheat Flour: Instrumental And Nutritional Quality Characterization Of Resulting Breads, Mahmoud Said Rashed, Milica Pojić, Ciara Mcdonagh, Eimear Gallagher, Jesus M. Frias, Shivani Pathania

Articles

Abstract: The present work investigated the structure-function relationship of dry fractionated oat flour (DFOF) as a techno-functional ingredient using bread as a model system. Mechanically, DFOF fractions (F), that is, F1: <224 µm, F2: 250–280 µm, F3: 280–500 µm, F4: 500–600 µm, and whole oat flour (F5) were blended with white wheat flour at 10%, 30%, and 50% substitution levels for bread making. The blended flours, doughs, and bread samples were assessed for their techno-functional, nutritional, and structural characteristics. The results of Mixolab and the Rapid Visco Analyzer show that the 50% substituted F3 fraction exhibits the highest water absorption properties (69.53%), whereas the 50% F1 fraction exhibits the highest peak viscosity of the past slurry. Analysis of bread samples revealed a lower particle size of DFOF fractions and higher supplementation levels, increased β-glucan levels (0.13–1.29 g/100 bread (db), reduced fermentable monosaccharides, that is, glucose (1.44–0.33 g/100 g), and fructose (1.06–0.28 g/100 g). The effect of particle size surpassed the substitution level effect on bread volume reduction. The lowest hardness value for F1 is 10%, and the highest value for F2 is 50%. The total number of cells in the bread slice decreased from the control to the F4 fraction (50%). Multi-criteria analysis indicated that DFOF fractions produced breads with similar structure and higher nutritional value developed from white wheat flour. Practical Application: The use of mechanically fractionated oat flours fractions in white wheat flour breads can improve the nutritional profile without affecting the physical properties of the bread product. Based on the oat flour fractions, bakers and food processing companies can tailor the bread formulations for high β-glucan, high fiber, and low reduced sugar claims.

Effects Of Cognitive And Social Demands On Linguistic Production For People With Moderate, Mild, Or No Aphasia, Tyson G. Harmon, Emily Mcdonald, Kyle Steele

Faculty Publications

Background: Most everyday communication occurs in situations where cognitive and social demands are present. These types of situations may compound language deficits for people with aphasia (PWA). An understanding of the language interference that may occur from cognitive and social demands is an important precursor for assessment and intervention that addresses everyday communication situations.

Aims: To determine how cognitively and socially demanding conditions affect micro- and macrolinguistic production for people with moderate, mild, or no aphasia during narrative discourse and to compare effects among groups.

Method: Thirty participants with mild (n = 9), moderate (n = 9), or no (n …

Elevato-Cdr: Speech Enhancement In Large Delay And Reverberant Assisted Living Scenarios, Swarnadeep Bagchi, Ruairí De Fréin

Conference papers

Speech enhancement algorithms are needed for Assisted Living (AL) environments, which are characterized by large inter-microphone spacings, significant phase-wraparound, and high reverberation times (T60). We contribute Elevato- CDR, which addresses the task of enhancing speech given the large relative delays and high levels of reverberation, which are characteristic of AL scenarios. The purpose of this paper is to evaluate Elevato-CDR’s performance and compare it with benchmark reverberation schemes, using speech mixtures which experience reverberation and background noise. Our findings indicate that Elevato-CDR successfully outperforms classical dereverberation algorithms in terms of subjective (MARS, PESQ) and objective (SDR, SRR) performance measures in …

The Impact Of Chief Audit Executive Turnover In Taiwan, Kenneth L. Bills, Hua-Wei Huang, Yi-Hung Lin, David A. Wood

Faculty Publications

This study adds to the emerging body of research showing the importance of internal audit to improve corporate governance and firm performance. Specifically, we test how the market reacts to the announcement of a turnover to the head of internal audit (i.e., the chief audit executive (CAE)). We find negative cumulative abnormal returns in the days surrounding the announcement of a CAE turnover and that the market holds a relatively negative perception of CAE turnover regardless of the reasons for the turnover event. We then study two reasons for why the market would react negatively to the CAE turnover and …

A Demonstration Of How Chatgpt Can Be Used In The Internal Auditing Process, Marc Eulerich, David A. Wood

Faculty Publications

For the past several years, internal audit functions (IAFs) have been significantly increasing their digitization efforts to enhance the efficiency and effectiveness of the IAF. The introduction of ChatGPT has increased the potential for IAFs to have a more significant impact; however, there is little guidance on how ChatGPT can influence the day-to-day work of internal auditors. This paper demonstrates with specific examples how ChatGPT can be used to enhance all aspects of the audit process. While not comprehensive in nature, the detailed, illustrative examples should help internal auditors see actionable steps they can take to be more efficient and …

Reassessing Assurance In An Automated World: Insights From Board Members, Executives, And Internal Auditors, Scott Emett, Marc Eulerich, Jeffrey Pickerd, David A. Wood

Faculty Publications

Technological advances that automate work continue to transform the accounting profession. We examine whether automation impacts resource allocation within the internal audit function (IAF), a unique setting that allows us to compare demand for assurance activities with demand for consulting activities. We conduct an experiment in which experienced board members, executives, and internal auditors make budget recommendations for a company’s IAF that developed automations that improved the efficiency of the IAF. Results show that across all groups, participants respond to these efficiencies by decreasing the IAF’s total budget but retaining the productive capacity of the IAF. The budget cuts are …

Disclosure Benchmarking By Lawyers: Evidence Fromthe Ipo Setting, Michael S. Drake, Jeff Mcmullin, Kenneth Merkley, Chase Potter, John Treu

Faculty Publications

Lawyers play an important advisory role in drafting financial reports, yet empirical evidence documenting the influence of external legal counsel on this process remains sparse. This study focuses on a specific aspect of lawyers’ drafting process: the practice of reviewing disclosures previously filed by other issuers—a practice termed “disclosure benchmarking.” Using initial public offering (IPO) disclosures as the setting, we find that disclosure benchmarking is associated with amore efficient Securities and Exchange Commission (SEC) review process. We further find that it is associated with several measures of disclosure quality, including disclosures that are less likely to be revised in subsequent …

The game utilises the ubiquity of QR codes and NFC in modern mobile devices, enabling users to seamlessly interact with …

Myopia Progression Patterns Among Paediatric Patients In A Clinical Setting, Michael Moore, Gareth Lingham, Daniel Ian Flitcroft, James Loughman

Articles

Purpose

This retrospective analysis of electronic medical record (EMR) data investigated the natural history of myopic progression in children from optometric practices in Ireland.

Methods

The analysis was of myopic patients aged 7–17 with multiple visits and not prescribed myopia control treatment. Sex- and age-specific population centiles for annual myopic progression were derived by fitting a weighted cubic spline to empirical quantiles. These were compared to progression rates derived from control group data obtained from 17 randomised clinical trials (RCTs) for myopia. Linear mixed models (LMMs) were used to allow comparison of myopia progression rates against outputs from a predictive …

Nonlinear Spatial Evolution Of Degenerate Quartets Of Water Waves, Conor Heffernan, Amin Chabchoub, Raphael Stuhlmeier

School of Engineering, Computing and Mathematics

In this manuscript we investigate the Benjamin–Feir (or modulation) instability for the spatial evolution of water waves from the perspective of the discrete, spatial Zakharov equation, which captures cubically nonlinear and resonant wave interactions in deep water without restrictions on spectral bandwidth. Spatial evolution, with measurements at discrete locations, is pertinent for laboratory hydrodynamic experiments, such as in wave flumes, which rely on time-series measurements at fixed gauges installed along the facility. This setting is likewise appropriate for experiments in electromagnetic and plasma waves. Through a reformulation of the problem for a degenerate quartet, we bring to bear techniques of …

Cities should strive to create public spaces that promote walking by designing pedestrian-friendly infrastructure that is accessible, safe, and convenient for all. An essential step in designing pedestrian-friendly infrastructure is understanding pedestrian usage patterns and behaviour in existing public spaces and infrastructure.

Using Content Analysis And Text Mining To Examine The Effects Of Asynchronous Online Tutoring On Revision, Susan Lang, Clinton Morrison Jr, Kathleen Brawley

The Writing Center Journal

What do writers do with the feedback they receive? While the answer will vary depending on the writer’s experience and the rhetorical situation, understanding what writers do can provide important information for course redesign and professional development of tutors and instructors. In this first of two manuscripts, the authors examine how first-semester, first-year writing students use responses provided via asynchronous online tutoring (AOT) in revising their assignments. Our primary research question was: What was happening in—and after—those tutorials? We addressed this question by a process of narrowing and refining of data analysis toward increasingly precise inferences as we progressed from …

“Hopes And Fears”: What Do Writing Center Administrators Think Of Merging With Or Converting Into A Learning Center?, Jenny Goransson

The Writing Center Journal

This article shares findings from a survey study (n = 73) focused on writing center administrator (WCA) perceptions of two phenomena we see on many secondary and postsecondary campuses in recent years: writing centers expanding to become learning centers, and writing centers consolidating or merging with other tutoring services on campus. Through analysis of the qualitative, open-ended survey responses, the study revealed that WCAs’ views of these trends are greatly impacted by local conditions and levels of autonomy, as well as WCAs’ beliefs about expertise. Also, consolidation and expansion are seen by WCAs as shifting writing center identity in …

Improving The Performance Of Hirep Lattice Simulations Software By Exploiting The Cpu Hardware Architecture Details And Algorithm Characteristics, Md Rahman

School of Engineering, Computing and Mathematics Theses

In the scientific exploration of Quantum Chromodynamics (QCD)—the theory governing the strong interaction among quarks and gluons—large-scale numerical simulations are per formed using the framework of lattice gauge theories. Lattice Gauge Theory (LGT) simulations involve the formulation of gauge field theories on a space-time lattice. HiRep is a simulation suite designed for running lattice simulations, leveraging high-performance computing platforms. HiRep is designed to be flexible enough to study a wide range of strongly interacting systems, particularly those pertinent to novel physics investigations at CERN’s Large Hadron Collider (LHC).
