Investigation Of Innovation In Wine Industry Via Meta-Analysis, Ali Dogru, Joseph Peyrefitte

Faculty Publications

This study provides a systematic review of 76 relevant wine business studies published in the last 30 years. Our meta-analysis investigates six commonly used variables to explain wine innovation: absorptive capacity, technology adoption, sustainable practices, export orientation, firm size, and firm age. We also investigate the association between innovation and financial performance, using the reported effect sizes in the literature. Our meta-analysis reveals that absorptive capacity, technology adoption, sustainable practices, export orientation, and firm size positively correlate with innovation efforts, and innovation is positively associated with financial performance. However, we find no correlation between firm age and innovation. In addition …

A Comparison Of Sporadic-E Occurrence Rates Using Gps Radio Occultation And Ionosonde Measurements, Rodney Carmona, Omar A. Nava, Eugene V. Dao, Daniel J. Emmons

Faculty Publications

Sporadic-E (E_s) occurrence rates from Global Position Satellite radio occultation (GPS-RO) measurements have shown to vary by a factor of five between studies, motivating the need for a comparison with ground-based measurements. In an attempt to find accurate GPS-RO techniques for detecting E_s formation, occurrence rates derived using five previously developed GPS-RO techniques are compared to ionosonde measurements over an eight-year period from 2010–2017. GPS-RO measurements within 170 km of a ionosonde site are used to calculate E_s occurrence rates and compared to the ground-truth ionosonde measurements. The techniques are compared individually for each ionosonde site …

Surface Acoustic Wave (Saw) Sensors: Physics, Materials, And Applications, Debdyuti Mandal, Sourav Banerjee

Faculty Publications

Surface acoustic waves (SAWs) are the guided waves that propagate along the top surface of a material with wave vectors orthogonal to the normal direction to the surface. Based on these waves, SAW sensors are conceptualized by employing piezoelectric crystals where the guided elastodynamic waves are generated through an electromechanical coupling. Electromechanical coupling in both active and passive modes is achieved by integrating interdigitated electrode transducers (IDT) with the piezoelectric crystals. Innovative meta-designs of the periodic IDTs define the functionality and application of SAW sensors. This review article presents the physics of guided surface acoustic waves and the piezoelectric materials …

Development Of Advanced Machine Learning Models For Analysis Of Plutonium Surrogate Optical Emission Spectra, Ashwin P. Rao, Phillip R. Jenkins, John D. Auxier Ii, Michael B. Shattan, Anil K. Patnaik

Faculty Publications

This work investigates and applies machine learning paradigms seldom seen in analytical spectroscopy for quantification of gallium in cerium matrices via processing of laser-plasma spectra. Ensemble regressions, support vector machine regressions, Gaussian kernel regressions, and artificial neural network techniques are trained and tested on cerium-gallium pellet spectra. A thorough hyperparameter optimization experiment is conducted initially to determine the best design features for each model. The optimized models are evaluated for sensitivity and precision using the limit of detection (LoD) and root mean-squared error of prediction (RMSEP) metrics, respectively. Gaussian kernel regression yields the superlative predictive model with an RMSEP of …

Ultrafast High-Energy Micro-Supercapacitors Based On Open-Shell Polymer-Graphene Composites, Lulu Yao, Naresh Eedugurala, Paramasivam Mahalingavelar, Daniel J. Adams, Kaiping Wang, Kevin S. Mayer, Jason D. Azoulay, Tse Nga Ng

Faculty Publications

Micro-supercapacitors are poised to serve as on-chip power sources for electronics. However, the challenge to simultaneously increase their power, energy, and lifetime demands new material combinations beyond current carbon-based systems. Here, we demonstrate that electro-deposition of an open-shell conjugated polymer with reduced graphene oxide achieves electrodes with capacitance up to 186 mF cm⁻² (372 F cm⁻³). The extended delocalization within the open-shell polymer stabilizes redox states and facilitates a 3 V wide potential window, while the hierarchical electrode structure promotes ultrafast kinetics. The micro-supercapacitor shows a high power density of 227 mW cm⁻² with an energy …

Search For Continuous Gravitational Waves From 20 Accreting Millisecond X-Ray Pulsars In O3 Ligo Data, Ligo Scientific Collaboration, Virgo Collaboration, Kagra Collaboration, Tiffany Z. Summerscales

Faculty Publications

Results are presented of searches for continuous gravitational waves from 20 accreting millisecond x-ray pulsars with accurately measured spin frequencies and orbital parameters, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors. The search algorithm uses a hidden Markov model, where the transition probabilities allow the frequency to wander according to an unbiased random walk, while the J-statistic maximum-likelihood matched filter tracks the binary orbital phase. Three narrow subbands are searched for each target, centered on harmonics of the measured spin frequency. The search yields 16 candidates, consistent with a false alarm probability of …

Family History Of Fxtas Is Associated With Age-Related Cognitive-Linguistic Decline Among Mothers With The Fmr1 Premutation, Jessica Klusek, Amanda Fairchild, Carly Moser, Marsha R. Mailick, Angela John Thurman, Leonard Abbeduto

Faculty Publications

BACKGROUND: Women who carry a premutation allele of the FMR1 gene are at increased vulnerability to an array of age-related symptoms and disorders, including age-related decline in select cognitive skills. However, the risk factors for age-related decline are poorly understood, including the potential role of family history and genetic factors. In other forms of pathological aging, early decline in syntactic complexity is observed and predicts the later onset of neurodegenerative disease. To shed light on the earliest signs of degeneration, the present study characterized longitudinal changes in the syntactic complexity of women with the FMR1 premutation across midlife, and associations …

Powell, Samantha L. Rogers, Thomas W. Sherry, David P.L. Toews, Andreanna J. Welch, Sabrina S. Taylor, Brady A. Porter

Faculty Publications

Identifying the composition of avian diets is a critical step in characterizing the roles of birds within ecosystems. However, because birds are a diverse taxonomic group with equally diverse dietary habits, gaining an accurate and thorough understanding of avian diet can be difficult. In addition to overcoming the inherent difficulties of studying birds, the field is advancing rapidly, and researchers are challenged with a myriad of methods to study avian diet, a task that has only become more difficult with the introduction of laboratory techniques to dietary studies. Because methodology drives inference, it is important that researchers are aware of …

Instructional Design Framework For Construction Materials Training, Hazem Jadallah, Carol J. Friedland, Isabelina Nahmens, Charles Pecquet, Charles Berryman, Yimin Zhu

Faculty Publications

The construction industry is suffering, in part, from a lack of training programs offered to the construction workforce. Unfortunately, most construction training and education research focuses on university student education. Integrating education science theory into construction workforce training has the potential to improve industry training but there is a dearth of studies that present details of this integration process. To address this gap, a training framework was developed to educate material stakeholders on material properties, selection, and installation. This framework is based on andragogical and Universal Design for Learning (UDL) principles. An assessment method evaluates training agendas to improve upon …

In 1987, Marianne Siegmund interviewed her parents (Elsa and Max Siegmund) about their lives, which included her own life experiences as well. The family members are of Transylvanian Saxon origins, coming from a minority German-speaking group that has lived in Transylvania (within Hungary and Romania) since the early Middle Ages. This family saga extends in time from World War One through the 1950s and beyond. (The interviews do not necessarily follow chronologically, however.) The family history begins in Székelyudvarhely, a town in Transylvania that has been divided and redivided between Hungary and Romania a number of times. Because of both …

Distributed Matrix Tiling Using A Hypergraph Labeling Formulation, Avah Banerjee, Maxwell Reeser, Guoli Ding

Faculty Publications

Partitioning large matrices is an important problem in distributed linear algebra computing, used in ML among others. Briefly, our goal is to perform a sequence of matrix algebra operations in a distributed manner on these large matrices. However, not all partitioning schemes work well with different matrix algebra operations and their implementations (algorithms). This is a type of data tiling problem. In this paper we consider a data tiling problem using hypergraphs. We prove some hardness results and give a theoretical characterization of its complexity on random instances. Additionally we develop a greedy algorithm and experimentally show its efficacy.

Challenges, Inquiry, And Recommendations: Effective Covid-19 Vaccine Management In The Face Of Public Mistrust And Concern, Rosemary M. Caron, M. Girard Dorsey

Faculty Publications

By examining concerns about safety, compliance, and distribution through an interdisciplinary approach of public health and history, we argue that historical and contemporary mistrust of immunizations serves to challenge the successful management of a COVID-19 vaccine program in the U.S. Unique circumstances surrounding the development of a COVID-19 vaccine, including pressure for rapid production, unclear communication from public health officials, and existing resistance to behavioral protective public health policy measures (e.g., mask-wearing) complicate widespread vaccine adoption. Currently, the demand for first and second COVID-19 vaccine doses, as well as the COVID-19 booster, continues to fluctuate in the U.S. population as …

Cognitive Decline And The Workplace, Sharona Hoffman

Faculty Publications

Cognitive decline will increasingly become a workplace concern because of three intersecting trends. First, the American population is aging. In 2019, 16.5 percent of the population, or fifty-four million people, were age 65 and over, and the number is expected to increase to seventy-eight million by 2025. Dementia is not uncommon among older adults, and by the age of eighty-five, between twenty-five and fifty percent of individuals suffer from this condition. Second, individuals are postponing retirement and prolonging their working lives. For example, about a quarter of physicians are over sixty-five, as are fifteen percent of attorneys. The average age …

Professional Speech At Scale, Cassandra Burke Robertson, Sharona Hoffman

Faculty Publications

Regulatory actions affecting professional speech are facing new challenges from all sides. On one side, the Supreme Court has grown increasingly protective of professionals’ free speech rights, and it has subjected regulations affecting that speech to heightened levels of scrutiny that call into question traditional regulatory practices in both law and medicine. On the other side, technological developments, including the growth of massive digital platforms and the introduction of artificial intelligence programs, have created brand new problems of regulatory scale. Professional speech is now able to reach a wide audience faster than ever before, creating risks that misinformation will cause …

Drawing from conflict resolution theory and social justice frameworks, the presentation emphasizes the importance of intentional dialogue, relationship-building, and process-oriented leadership in navigating intergroup conflict and institutional inequities. Rashid offers a model for leaders to engage stakeholders meaningfully and argues that sustainable change emerges through shared ownership, vulnerability, and …

Using Situational Analysis To Reimagine Infrastructure, Mary Le Rouge, Clancy Ratliff, Donnie Johnson Sackey

Faculty Publications

In this article, we ask what it means to think of infrastructure discursively through situational analysis. First, we consider how policymakers have historically used writing and rhetoric to redefine, reframe, and resituate what infrastructure can be in technical documents. Second, we address the impact of policymakers’ discursive practices on the spaces and material realities of communities. We view the infrastructural function of writing “as a conceptual foundation for revealing structures and foundations of organizations that affect people” (Read, 2019, p. 237). We use three texts as the space of our discourse mapping: President Franklin Roosevelt’s “Fireside Chat on the Recovery …
