Covid-19 And Transition To Distance Learning: Perspectives Of Postsecondary Teachers In Kenya, James Ogechi Kereri, Grace Moraa Kennedy, Dovison Kereri

Faculty Publications

Several countries have transitioned to online and/or virtual learning to minimize the impact of Covid-19 on education. In Kenya, schools were closed for the better part of 2020 and reopened back on relying on an online mode and/or virtual learning. However, very little is known about the impact of such transition on postsecondary educators. Therefore, this research aims to bridge this gap by investigating the impact of online and/or virtual learning transition on postsecondary educators based on age, gender, location, and academic rank. Using a nationally distributed web-based survey, the study utilized data from 117 educators across Kenya who participated …

Tobacco 21 Laws May Reduce Smoking And Tobacco-Related Health Disparities Among Youth In The U.S., David C. Colston, Yanmel Xie, Megan E. Patrick, Jim F. Thrasher Ph.D., Ma, Ms, Andrea R. Titus, Michael R. Elliot, David T. Levy, Nancy L. Fleischer

Faculty Publications

The goal of our study is to understand the impact of Tobacco 21 (T21) laws on youth smoking and health equity. We conducted modified Poisson regression models using 2014–2019 Monitoring the Future data to measure the impact of attending school in a county 100% covered by a T21 law versus counties with <100% T21 coverage on past 30-day smoking participation (n = 262,632), first cigarette smoking initiation (n = 189,698), and daily smoking initiation among 8th, 10th, and 12th graders (n = 214,496), separately. Additive interactions were tested between T21 coverage and sex, race/ethnicity, parental education, and college plans. T21 coverage was associated with a lower likelihood of smoking participation among 12th graders. T21 coverage was most strongly associated with a lower likelihood of smoking participation among: Hispanic and NH (Non-Hispanic) Other/Multiracial individuals; respondents with parents who had less than a college education; and respondents who were not definitely planning on attending college. T21 laws were associated with a lower likelihood of smoking participation among 12th graders. T21 policies were most impactful for individuals disproportionately impacted by tobacco, indicating T21 laws might help reduce tobacco-related health disparities.

Smith's Last Stand? Free Exercise And Foster Care Exceptionalism, James G. Dwyer

Faculty Publications

Part I first situates Fulton [Fulton v. City of Philadelphia] within two broader contexts—the clash between social equality rights for sexual minorities and religious freedom, and a pattern of eliding children from legal contests over their lives. It then explains why the standard constitutional framing of social equality versus religious freedom contests is improper when the state is acting as guardian and proxy for children or other non-autonomous persons. Part II sets out a proper framework for analyzing these conflicts, elucidating the scope and nature of the state’s parens patriae authority—a lacuna in constitutional jurisprudence. Part III applies …

Reducing Administrative Burdens To Protect Taxpayer Rights, Leslie Book, T. Keith Fogg, Nina E. Olson

Faculty Publications

The tax system designed by Congress imposes significant administrative burdens on taxpayers. IRS decisions regarding how it administers tax laws can add to congressionally imposed burdens. The administrative burdens are consequential and hurt some people, especially lower- or moderate- income individual taxpayers, more than others. While the IRS strives to measure and reduce the time and money taxpayers spend to comply with their tax obligations, it does not consider the effect administrative burdens have on taxpayer rights, including the right to be informed, the right to pay no more than the correct amount of tax, and the right to a …

Faculty Publications

Subterranean termites depend nutritionally on their gut microbiota, which includes protozoa as well as taxonomically and functionally diverse bacteria. Our previous metavirome study revealed a high diversity and novel families of bacteriophages in the guts of Coptotermes formosanus workers from New Orleans, Louisiana, United States. Two assembled bacteriophage genomes (Phages TG-crAlp-04 and 06, family Podoviridae) existed in all colonies and showed similarity to a prophage (ProJPt-Bp1) previously sequenced from a bacterial endosymbiont (Candidatus Azobacteroides pseudotrichonymphae, CAP) of protozoa in the gut of a termite species of the genus Prorhinotermes from Taiwan. In this study the genomes of Phage TG-crAlp-04 and …

Semantic Segmentation To Extract Coronary Arteries In Invasive Coronary Angiograms, Chen Zhao, Robert Bober, Haipeng Tang, Jinshan Tang, Minghao Dong, Chaoyang Zhang, Zhuo He, Michele L. Esposito, Zhihiu Xu, Weihua Zhou

Faculty Publications

Accurate semantic segmentation of each coronary artery using invasive coronary angiography (ICA) is important for stenosis assessment and coronary artery disease (CAD) diagnosis. In this paper, we propose a multi-step semantic segmentation algorithm based on analyzing arterial sements extraced from ICAs. The proposed algorithm firstly extracts the entire arterial binary mask (binary vascular tree) using a deep learning-based method. Then we extract the centerline of the binary vascular tree and separate it into different arterial segments. Finally, by extracting the underlyingarterial topology, position, and pixel features, we construct a powerful coronary artery segment classifier based on a support vector machine. …

Soil Salinity Estimation Over Coastal Wetlands Based On Random Forest Algorithm And Hydrological Connectivity Metric, Haochen Sui, Dawei Chen, Jiaguo Yan, Bin Li, Wei Li, Baoshan Cui

Faculty Publications

Owing to climate warming and human activities (irrigation and reservoirs), sea level rise and runoff reduction have been threatening the coastal ecosystem by increasing the soil salinity. However, short-term sparse in situ observations limit the study on the response of coastal soil salinity to external stressors and thus its effect on coastal ecosystem. In this study, based on hydrological connectivity metric and random forest algorithm (RF), we develop a coastal soil salinity inversion model with in situ observations and satellite-based datasets. Using Landsat images and ancillary as input variables, we produce a 30-m monthly grid dataset of surface soil salinity …

Identification Of Micrornas In The Lyme Disease Vector Ixodes Scapularis, Deepak Kumar, Latoyia P. Downs, Monica Embers, Alex Sutton Flynt, Shahid Karim

Faculty Publications

MicroRNAs (miRNAs) are a class of small non-coding RNAs involved in many biological processes, including the immune pathways that control bacterial, parasitic, and viral infections. Pathogens probably modify host miRNAs to facilitate successful infection, so they might be useful targets for vaccination strategies. There are few data on differentially expressed miRNAs in the black-legged tick Ixodes scapularis after infection with Borrelia burgdorferi, the causative agent of Lyme disease in the United States. Small RNA sequencing and qRT-PCR analysis were used to identify and validate differentially expressed I. scapularis salivary miRNAs. Small RNA-seq yielded 133,465,828 (≥18 nucleotides) and 163,852,135 (≥18 …

Nutrition and physical activity are risk factors for many chronic diseases including cancer and cardiovascular disease, the leading causes of death in the United States. Lifestyle management programs to address obesity and potential sequelae such as chronic conditions have shown efficacy, with social support an important factor in interventions. Instruments that assess social support specifically provided by friends are lacking but could be important predictors of program success. The purpose of this study was to examine the reliability and validity of the 10-item Social Support …

Needs Assessment Of Southeastern United States Vector Control Agencies: Capacity Improvement Is Greatly Needed To Prevent The Next Vector-Borne Disease Outbreak, Kyndall C. Dye-Braumuller, Jennifer R. Gordon, Danielle John, Josie Morrissey, Kaci Mccoy, Rhoel R. Dinglasan, Melissa Nolan Ph.D., Mph

Faculty Publications

A national 2017 vector control capacity survey was conducted to assess the United States’ (U.S.’s) ability to prevent emerging vector-borne disease. Since that survey, the southeastern U.S. has experienced continued autochthonous exotic vector-borne disease transmission and establishment of invasive vector species. To understand the current gaps in control programs and establish a baseline to evaluate future vector control efforts for this vulnerable region, a focused needs assessment survey was conducted in early 2020. The southeastern U.S. region was targeted, as this region has a high probability of novel vector-borne disease introduction. Paper copies delivered in handwritten envelopes and electronic copies …

Testing Seefeldt's Proficiency Barrier: A Longitudinal Study, Fernando Garbeloto Dos Santos, Matheus Maia Pacheco, David F. Stodden Ph.D., Go Tani, José António Ribeiro Maia

Faculty Publications

The idea that proficiency in the fundamental movement skills (FMS) is necessary for the development of more complex motor skills (i.e., the proficiency barrier) and to promote health-enhancing physical activity and health-related physical fitness levels is widespread in the literature of motor development. Nonetheless, to the best of our knowledge, there is no study assessing whether children presenting proficiency below a specified proficiency barrier would demonstrate difficulty in improving performance in more complex skills—even when subjected to a period of practice in these complex skills. The present study tested this. Eighty-five normal children (44 boys) aged 7 to 10 years …

Branching Off: New Insight Into Lysosomes As Tubular Organelles, K A. Bohnert, A E. Johnson

Faculty Publications

Lysosomes are acidic, membrane-bound organelles that play essential roles in cellular quality control, metabolism, and signaling. The lysosomes of a cell are commonly depicted as vesicular organelles. Yet, lysosomes in fact show a high degree of ultrastructural heterogeneity. In some biological contexts, lysosome membranes naturally transform into tubular, non-vesicular morphologies. Though the purpose and regulation of tubular lysosomes has been historically understudied, emerging evidence suggests that tubular lysosomes may carry out unique activities, both degradative and non-degradative, that are critical to cell behavior, function, and viability. Here, we discuss recent advances in understanding the biological significance of tubular lysosomes in …

Oxen: Status, Uses And Practices In The U.S.A., Encouraging A Historic Tradition To Thrive, Andrew B. Conroy

Faculty Publications

Oxen in the United States of America have played an important role throughout its history. Unlike other countries,oxen were never completely given up for horses, mules, or tractors. Instead, the culture of keeping oxen has been maintained by a small group of teamsters in the North- eastern states collectively called New England. Their continued presence has been largely due to agricultural fairs and exhibitions where they have been used in competition for the last 200 years. Ox teamsters were sur- veyed in 2021via social media using Qualtrics. The 423 ox teamsters responding owned 1791 oxen in 39 states, with the …

Don't Forget The "G" In Esg: The Sec And Corporate Governance Disclosure, Jennifer O'Hare

Faculty Publications

For years, many shareholders—both institutional and individual investors—have pressured the Securities and Exchange Commission (“SEC”) to require public companies to disclose more information about the environmental, social, and governance (“ESG”) risks facing the company. However, the SEC has generally refused calls to require public corporations to disclose, for example, how they are addressing climate change or workforce diversity challenges. With a new president in the White House and a new administration at the SEC, the SEC will soon propose new ESG disclosure rules, requiring more information about the “E” and the “S” in ESG. But the SEC has forgotten the …

Institutional Betrayals As Sex Discrimination, Emily Suski

Faculty Publications

Title IX jurisprudence has a theoretical and doctrinal inadequacy. Title IX’s purpose is to protect public school students from sex discrimination in all its forms. Yet, courts have only recognized three relatively narrow forms of sex discrimination under it. Title IX jurisprudence, therefore, cannot effectively recognize as sex discrimination the independent injuries, called institutional betrayals, that schools impose on students because they have suffered sexual harassment. Institutional betrayals occur when schools betray students’ trust in or dependency on them by failing to help students in the face of their sexual harassment. These injuries cause harms that can be more severe …
