Scaler Rates From The Pierre Auger Observatory: A New Proxy Of Solar Activity, S. Mancuso, A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte, K. Almeida Cheminant, B. Fick, K. Nguyen, D. Nitz, Et Al.

Michigan Tech Publications

The modulation of low-energy galactic cosmic rays reflects interplanetary magnetic field variations and can provide useful information on solar activity. An array of ground-surface detectors can reveal the secondary particles, which originate from the interaction of cosmic rays with the atmosphere. In this work, we present an investigation of the low-threshold rate (scaler) time series recorded in 16 yr of operation by the Pierre Auger Observatory surface detectors in Malargüe, Argentina. Through an advanced spectral analysis, we detected highly statistically significant variations in the time series with periods ranging from the decadal to the daily scale. We investigate their origin, …

Psychometric Properties Of The Indonesian Version Of The Quality Of Life Index (Qli-I) Among Family Caregivers Of Dependent Older Persons With Type 2 Diabetes Mellitus, Rinco Siregar, Charuwan Kritpracha, Tippamas Chinnawong, Jos M. Latour

School of Nursing and Midwifery

Background: The quality of life (QoL) of family caregivers supporting older persons with functional dependence due to Type 2 Diabetes Mellitus (T2DM) is a growing concern. Accurately assessing caregiver well-being requires culturally appropriate, valid, and reliable instruments. However, such tools remain limited in the Indonesian context. Objective: This study aimed to translate the Quality of Life Index (QLI) into Indonesian and evaluate the psychometric properties of the Indonesian version (QLI-I) among family caregivers of dependent older persons with T2DM. Methods: Brislin’s back-translation method was used to ensure linguistic and conceptual equivalence in the translation process. Content validity was assessed by …

Co-Operative Care: The Case For Worker Co-Operative Elder Care In Ireland, Gerard Doyle

Research Outputs: 2025-Present

Ireland’s population age profile is forecasted to increase over the coming decades which will have implications for the care responsibilities of families and the state. However, there is a paucity of quality elder care in Ireland. Elder care worker co-operatives could contribute to meeting this shortfall in supply. This study examines the impact of co-owned elder care provision in Ireland. A case study approach is employed with the Great Care Co-op (GCC) being the case selected. The findings emphasise that the GCC provides a quality service to its care recipients. The careworker members and family members of care recipients both …

The Methane Clumped Isotope Signatures Of The Acetoclastic And Methylotrophic Methanogenesis Pathways, Mia L. Thompson

Dartmouth College Master’s Theses

Methane is a potent greenhouse gas and critical energy source for the global economy. Atmospheric methane concentrations play a critical role in global warming, while mitigating methane emissions may provide route to short-term reduction of warming effects. In order to track rates and sources of emissions, it is first necessary to understand the sources and sinks of methane; yet, there are challenges in distinguishing abiotic (water/rock), thermogenic, and biogenic methane. Traditional approaches of using the bulk isotopes of carbon (δ¹³C) and hydrogen (δD) of methane have limitations due to overlapping signatures and sensitivity to substrate isotope composition. In …

The Ghannouchi Test: The Compatibility Of Religious Ideas And Secular Democracy, Andrew P. Sheppe

Dartmouth College Master’s Theses

Secular, democratic societies and governments evolved out of religious societies and defined themselves partially in opposition to religious authority. This historical relationship has led to a debate about the compatibility between religious ideas and modern, secular society. Ernst-Wolfgang Böckenförde posited that secular, democratic societies still depend on religious foundations. Jürgen Habermas disagrees, claiming that processes of rational dialogue can provide sufficient support.

Two prominent twentieth century theologians, Reinhold Niebuhr and Abraham Joshua Heschel demonstrate that democratic systems are enriched and protected by theistic ideas, thus supporting Böckenförde’s dictum. However, they both recognize the importance of epistemic humility and a …

Telogen Effluvium And Anesthesia Considerations: A Case Report., Elizabeth Johnson-Gray, Samantha A Currier, Hanen Fernandez, Matt Brown, Matthias Franzen

Ambulatory and Primary Care Articles

Telogen effluvium is a form of non-scarring hair loss characterized by premature shedding of hair. Pathophysiologically, telogen effluvium occurs when a significant number of hair follicles prematurely enter the telogen phase, resulting in excessive shedding. The exact mechanism is unclear, but it is believed to involve alterations in the hair follicle's growth cycle, possibly mediated by illness, infection, major surgery, low protein intake, or hormonal changes. Some medications can also be linked to this disease, such as beta blockers, carbamazepine, and vitamin A. When affected hairs are in the resting phase, noticeable hair shedding occurs. Our patient was a 61-year-old …

A Phenomenological Study On The Enabling Role Of Digital Competencies In Heutagogical Learning Contexts, Jennifer Dean

Masters

This study examines how digital competencies contribute to independent learning within heutagogical contexts in higher education.   The research was conducted to address assumptions that digital competence directly enables learner autonomy, despite limited understanding of this empirical relationship in practice.   A qualitative hermeneutic phenomenological approach was employed, using nine semi-structured interviews to explore learners’ lived experiences in digitally mediated environments.   The findings indicate that self-directed learning is primarily driven by intrinsic motivation and often occurs unconsciously.   Digital competencies were found to act as enabling factors by facilitating access, flexibility and engagement, however, their influence on autonomy was context-dependent rather than deterministic. …

Expanding Equity And Innovation In Pharmaceutical Law And Drug Development: Paying Clinical Trial Participants For Their Data, Steve Calandrillo, Bernadette Tosti, Jefferson Smith, Jamison Koeman

Articles

Bringing a drug to market is exceedingly expensive and exposes pharmaceutical manufacturers to significant legal risk. But when companies are successful, their profits make the PowerBall jackpot look like petty cash. Staggering rewards measure in the billions or millions for the firms, CEOs, pharmacies, drug benefit managers, data brokers, and many more actors in the pharmaceutical-to-patient pipeline. The only individuals who don’t get paid handsomely are the clinical trial participants, whose voluntary participation and data helped make those successes possible. It is long past time that we reform the legal and regulatory roadblocks to paying clinical trial participants in the …

Torus Probabilistic Principal Component Analysis, Anahita Nodehi, Mousa Golalizadeh, Mehdi Maadooliat, Claudio Agostinelli

Mathematical and Statistical Science Faculty Research and Publications

Analyzing data in non-Euclidean spaces, such as bioinformatics, biology, and geology, where variables represent directions or angles, poses unique challenges. This type of data is known as circular data in univariate cases and can be termed spherical or toroidal in multivariate contexts. In this paper, we introduce a novel extension of probabilistic principal component analysis (PPCA) designed for toroidal (or torus) data, termed torus probabilistic PCA (TPPCA). We provide detailed algorithms for implementing TPPCA and demonstrate its applicability to torus data. To assess the efficacy of TPPCA, we perform comparative analyses using a simulation study and three real datasets. Our …

Graph Convolutional Networks Enable Fast Hemorrhagic Stroke Monitoring With Electrical Impedance Tomography, J. Toivanen, V. Kolehmainen, A. Paldanius, A. Hänninen, A. Hauptmann, Sarah J. Hamilton

Mathematical and Statistical Science Faculty Research and Publications

Objective: To develop a fast image reconstruction method for stroke monitoring with electrical impedance tomography with image quality comparable to computationally expensive nonlinear model-based methods. Methods: A post-processing approach with graph convolutional networks is employed. Utilizing the flexibility of the graph setting, a graph U-net is trained on linear difference reconstructions from 2D simulated stroke data and applied to fully 3D images from realistic simulated and experimental data. An additional network, trained on 3D vs. 2D images, is also considered for comparison. Results: Post-processing the linear difference reconstructions through the graph U-net significantly improved the image quality, resulting in images …

Diet, Gut Microbiota, And Histidine Metabolism Toward Imidazole Propionate Production In Relation To Type 2 Diabetes, Yanbo Zhang, Christina Cordero, Bing Yu, Robert D Burk, Robert Kaplan, Qibin Qi

Faculty, Staff and Student Publications

Objective: To examine associations of serum imidazole propionate (ImP), histidine, and their ratio with incident type 2 diabetes (T2D) and related dietary and gut microbial factors in U.S. Hispanic/Latino people.

Research design and methods: In the Hispanic Community Health Study/Study of Latinos, we evaluated serum ImP, histidine, and ImP-to-histidine ratio at baseline (2008-2011) and their cross-sectional associations with dietary intake and prospective associations with incident T2D over ∼12 years (n = 4,632). In a subsample with gut microbiota data during a follow-up visit (2016-2018), we examined gut microbial species associated with serum ImP and their potential interactions with dietary intake. …
