The Obverse-Turing Test: Rethinking Authorship, Trust, And Time In An Accelerated Age, Michael J. Miller, Chatgpt (Ai~Nesbo+) Jan 2026

The Obverse-Turing Test: Rethinking Authorship, Trust, And Time In An Accelerated Age, Michael J. Miller, Chatgpt (Ai~Nesbo+)

Psychology

In this paper, we propose a new test for scientific accountability in the era of artificial intelligence: the Obverse Turing Test for Authorship. While the traditional Turing test focuses on a machine's ability to mimic human intelligence, our test addresses the question: when should a scientific contribution involving artificial intelligence be attributed joint authorship? We argue that more and more authors are using AI in the idea generation and elaboration stages of their work, but rarely acknowledge this use explicitly. To examine this gap, we analyze examples of human–AI interactions across fields and propose a new approach to authorship based …


Handbook On Gender Mainstreaming In The Maritime Sector, Momoko Kitada Jan 2026

Handbook On Gender Mainstreaming In The Maritime Sector, Momoko Kitada

Reports

This handbook aims to serve as an introductory practical guide for maritime organizations that intend to apply gender mainstreaming. It guides them in critically reviewing their policies and practices from a gender and diversity lens. Some organizations may view their maritime operations as having nothing to do with gender and, therefore, not requiring any gender considerations. Such mindsets are good signs that an organization would benefit from gender mainstreaming. Others may view the fact that their organizations have women working in every unit as evidence of gender equality and see no need for further action. Gender mainstreaming can help identify …


Development Of Multimodal Measurements And Analysis For Early Detection Of Alzheimer’S Disease, Fiza Saeed Jan 2026

Development Of Multimodal Measurements And Analysis For Early Detection Of Alzheimer’S Disease, Fiza Saeed

Bioengineering Dissertations

Alzheimer's disease (AD) is the leading cause of dementia, and existing diagnostic methods such as PET scans, cerebrospinal fluid sampling and biomarker quantification, and gene sequencing are all either invasive, costly, or not sensitive enough for early detection. This dissertation introduces three different studies that develop a novel multimodal, non-invasive approach to diagnosing AD at its early stages by combining broad band near infrared spectroscopy (bbNIRS) and electroencephalography (EEG) technologies.

The first study showed cerebrovascular-cerebrospinal fluid coupling (CBV-CSF), which is measured by using 2-channel bbNIRS as an indicator of brain aging and early AD. Linear correlations between total blood (Δ[HbT]) …

Modern Privacy, Outdated Doctrine: A Four-Factor Approach To Fourth Amendment Analysis, Ilinca Slabu Jan 2026

Modern Privacy, Outdated Doctrine: A Four-Factor Approach To Fourth Amendment Analysis, Ilinca Slabu

Washington Law Review Online

The Fourth Amendment, which protects individuals against unwarranted searches and seizures, has been at the center of many questions recently due to advancements in technology. Technology has evolved to a point where it is no longer necessary to enter someone’s physical space to know what is happening inside a home. This has led to many ambiguities between what is private and public, and what technology usage constitutes a search under the Fourth Amendment. We have reached a critical point that requires a clear test to determine this question to protect the privacy of individuals.

This Comment proposes a new framework …


Laser Beam Shaping Using A Neural Network, Azeem A. Hakim Jan 2026

Laser Beam Shaping Using A Neural Network, Azeem A. Hakim

Honors Undergraduate Theses

Multiphoton lithography (MPL) is a method of laser-based 3D-printing for fabricating micron-scale structures point-by-point in a photopolymerizable medium. MPL’s high-resolution capabilities have made it a powerful method for the fabrication of many devices, such as microelectromechanical systems (MEMS) and tissue scaffolds.  The throughput of MPL processes can be increased by using spatially shaped laser beams that expose large areas or volumes simultaneously. A laser beam can be reshaped by passing it through a spatial light modulator (SLM) displaying a pre-designed phase mask. One type of laser beam profile used for this purpose is the Bessel beam, a type of structured …

Alexander Duals Of Symmetric Simplicial Complexes And Stanley-Reisner Ideals, Ayah Almousa, Kaitlin Bruegge, Martina Juhnke-Kubitzke, Uwe Nagel, Alexandra Pevzner

Mathematics Faculty Publications

Given an ascending chain (In)n∈N of Sym-invariant squarefree monomial ideals, we study the corresponding chain of Alexander duals (In∨)n∈N. Using a novel combinatorial tool, which we call avoidance up to symmetry, we provide an explicit description of the minimal generating set up to symmetry in terms of the original generators. Combining this result with methods from discrete geometry, this enables us to show that the number of orbit generators of In∨ is given by a polynomial in n for sufficiently large n. The same is true for …

Human Capital And Development, Philippe Aghion, Ingvild Almås, Costas Meghir Jan 2026

Human Capital And Development, Philippe Aghion, Ingvild Almås, Costas Meghir

Discussion Papers

Human capital is central to efforts to promote growth, convergence, and the elimination of poverty. Drawing on the seminal macroeconomic frameworks by Nelson-Phelps, Lucas and subsequent developments, alongside macro and microeconomic evidence, we examine the role of human capital in driving innovation and growth. We highlight how different types of human capital, characterized by education level, matter in different stages of development. Despite documented increases in years of schooling, the world’s poorest regions still see stagnating outcomes in learning and education quality, potentially creating poverty traps where investments in neither physical nor human capital materialize. We discuss obstacles to human …

Differences In Biologic Clinical Trials For Chronic Rhinosinusitis With Nasal Polyps—Are We Comparing Apples With Oranges?, Marjolein Cornet, Peter W. Hellings, Martin Desrosiers, Martin Wagenmann, Richard Follows, Laura Walrave, Luz Adriana Jimenez, Lee Tombs, Dawn Edwards, Peter Howarth, Joseph K. Han

Department of Otolaryngology (ENT) Faculty Publications

In recent years, several biologics targeting Type 2 inflammation have been developed for treating chronic rhinosinusitis with nasal polyps (CRSwNP). These have been studied in registrational randomized controlled trials (RCTs), which vary in their patient populations, trial design, endpoints, geography, timing, or data-handling processes. While (in)direct treatment comparisons and meta-analyses have been carried out to compare efficacy results from RCTs, often these fail to properly account for these between-study differences. Here, we summarize the key between-study differences that can influence trial outcomes and highlight the resulting challenges faced when comparing outcomes from different Phase III RCTs of biologics in CRSwNP.

Evaluating The Effects Of Autonomous Learning, Goal Orientation And Self-Efficacy On The Academic Performance Of Ethiopian Stem Students’ Through Structural Equation Modeling (Sem), Jerusalem Yizengaw, Asnake Tarekegn Nigussie

Journal of Educational Technology Development and Exchange (JETDE)

The study investigates the relationships among self-efficacy, goal orientation, and autonomous learning and how these factors affect Ethiopian STEM students’ academic performance. A descriptive survey design using mixed-methods research was used. Semi-structured interviews and questionnaires were employed to gather data from eight teachers and 151 STEM students. CFA and EFA attested to the validity and reliability of the questionnaires. Quantitative data were assessed using structural equation modeling (SEM), and qualitative data were analyzed using word descriptions. Self-efficacy was positively correlated with STEM students’ academic performance (β = .12, p < .01), whereas autonomous learning and goal orientation were negatively correlated (β = -.01, p < .01) and (β = -.04, p < .01), respectively. Findings suggest that techniques that help Ethiopian STEM students develop self-efficacy should be prioritized, with implications for curriculum design and instructional approaches. According to the findings, methods that support Ethiopian STEM students in developing self-efficacy should be prioritized, with consequences for instructional strategies and curriculum design. Although self-belief appears crucial for success, further research is required to fully understand the complex interaction of these factors in Ethiopia and other contexts.

Case-Based Learning In Biology Education: A Systematic Literature Review, Elsje Theodora Maasawet, Jullya Christin Kolow

Journal of Educational Technology Development and Exchange (JETDE)

Biology education often relies on content-intensive instructional materials that may encourage rote memorisation rather than conceptual understanding, potentially contributing to misconceptions. Case-Based Learning (CBL) offers an alternative by engaging students in applying biological concepts to authentic, real-life cases and promoting meaningful learning. Despite growing empirical interest in CBL, no systematic literature review has specifically synthesised its application in biology education. This study therefore examined publication trends, learning skills addressed, and conceptualisations of CBL in biology education. Relevant literature was retrieved from Scopus and Web of Science using “Case-Based Learning” as the search term. Following PRISMA-guided screening, 42 articles were included …

Electrical & Computer Engineering Faculty Publications

Accurately forecasting the operating temperature of lithium-ion batteries (LIBs) is essential for preventing thermal runaway, extending service life, and ensuring the safe operation of electric vehicles and stationary energy-storage systems. This work introduces a unified, physics-informed, and data-driven temperature-prediction framework that integrates mathematically governed preprocessing, electrothermal decomposition, and sequential deep learning architectures. The methodology systematically applies the governing relations to convert raw temperature measurements into trend, seasonal, and residual components, thereby isolating long-term thermal accumulation, reversible entropy-driven oscillations, and irreversible resistive heating. These physically interpretable signatures serve as structured inputs to machine learning and deep learning models trained on temporally …


Markov Chain Wave Generative Adversarial Network For Bee Bioacoustic Signal Synthesis, Kumudu Samarappuli, Iman Ardekani, Mahsa Mohaghegh, Abdolhossein Sarrafzadeh Jan 2026

Markov Chain Wave Generative Adversarial Network For Bee Bioacoustic Signal Synthesis, Kumudu Samarappuli, Iman Ardekani, Mahsa Mohaghegh, Abdolhossein Sarrafzadeh

Electrical & Computer Engineering Faculty Publications

This paper presents a framework for synthesizing bee bioacoustic signals associated with hive events. While existing approaches like WaveGAN have shown promise in audio generation, they often fail to preserve the subtle temporal and spectral features of bioacoustic signals critical for event-specific classification. The proposed method, MCWaveGAN, extends WaveGAN with a Markov Chain refinement stage, producing synthetic signals that more closely match the distribution of real bioacoustic data. Experimental results show that this method captures signal characteristics more effectively than WaveGAN alone. Furthermore, when integrated into a classifier, synthesized signals improved hive status prediction accuracy. These results highlight the potential …
