Appalachian Caregiver Perspectives On Childhood Gun Safety In The Home, Dannell Boatman

Journal of Appalachian Health

Background: Childhood gun injuries pose a critical public health challenge. For children, unintentional gun injury deaths primarily occur in the home where parents or other adult guardians, referred to as caregivers hereafter, are responsible for safety. While the American Academic of Pediatrics recommends not having guns in areas where children live and play, firearms are often viewed as normative and fill an important role in many homes. This is particularly true in more rural areas, such as Appalachia, where there is a high density of gun ownership. Additional research is needed to understand rural caregivers’ current gun safety practices in …

The Effects Of Major Depressive Disorder On Cognition And The Brain, Ashlee Stewart, Lauren L. Harburger

Modern Psychological Studies

Major depressive disorder is commonly known for its prevalence and impairing effects on the brain and behavior. One such effect is a decrease in processing speed, which leads to slower response times and an increased difficulty performing tasks that require careful attention. Impairments in spatial ability have also been reported in depressed subjects, which may be linked to impairments in executive functioning. GABA is a neurotransmitter that has been shown to play a role in the symptoms of depression. This review will examine the effects of depression on cognitive functioning and the brain, and will suggest that future research examine …

Large-Scale Edna Metabarcoding Survey Reveals Marine Biogeographic Break And Transitions Over Tropical North-Western Australia, Katrina M. West, Michael J. Travers, Michael Stat, Euan S. Harvey, Zoe T. Richards, Joseph D. Dibattista, Stephen J. Newman, Alastair V. Harry, Craig L. Skepper, Matthew Heydenrych, Michael Bunce

Fisheries Research Articles

Environmental DNA (eDNA) metabarcoding has demonstrated its applicability as a highly sensitive biomonitoring tool across small spatial and temporal scales in marine ecosystems. However, it has rarely been tested across large spatial scales or biogeographical barriers. Here, we scale up marine eDNA metabarcoding, test its ability to detect a major marine biogeographic break and evaluate its use as a regional biomonitoring tool in Australia.

Controlling Schools: How School Resource Officers’ Roles Map Onto Schools’ Behavior Management Strategies, Ivan Benitez, Benjamin W. Fisher, Taylor Tolles, Emily M. Wright

Criminology and Criminal Justice Faculty Publications

School resource officer (SRO) behavior varies across schools, but little is known about what shapes their behavior. Social ecological theories state that features of communities shapes individual behavior, including police officers. This may similarly apply to SROs. This study uses the 2015 to 2016 School Survey on Crime and Safety to test the extent to which three aspects of a school’s context related to behavior management (i.e., security measures, disciplinary environment, and restorative practices) shape SROs’ involvement in three roles: law enforcement, teacher, and mentor. Using a generalized structural equation model to examine the relationships between school context and SRO …

Assessment Of Heavy Metal Concentration In Soils Around Geita The Gold Mine, Tanzania, Mariam G. Mgendi, Mkabwa L. K Manoko, W.J.S. Mwegoha, C. Southway C. Southway

Journal of Humanities and Social Sciences

Health issues related to gold mining cannot be underestimated. Gold mining produce acid mine drainage (AMD), which in turn releases heavy metals into the nearby environment, hence causing environmental pollution. Heavy metals are naturally very toxic, thus pose a great health concern especially when their concentration exceeds the recommended permissible limits. In this study, concentrations of five heavy metals—including Pb, Ni, Cr, Cu and Zn—were assessed in the soil around Geita Gold Mine (GGM). A total of 17 sampling sites were established from which the soil samples were collected at 0-15cm and 15-30cm soil depth. The concentration of both total …

Cancer is one of the dreaded diseases for which no drugs have been invented so far for its complete cure. While the world is advancing so fast with the advancement of science and technology, at the same time, new dreaded diseases continue to emerge around the world. One such global pandemic disease currently witnessing is COVID-19. No exact medicine has been developed to control and cure this new pandemic which has a serious impact on aged persons; patients of diabetics, asthma, cancer, pneumonia, etc. Some recent and current studies conducted around the world have shown us many facts about this. …

Stability Conditions For Coupled Autonomous Vehicles Formations, Pablo Baldivieso, J. J. P. Veerman

Mathematics and Statistics Faculty Publications and Presentations

In this paper, we give necessary conditions for stability of coupled autonomous vehicles in R. We focus on linear arrays with decentralized vehicles, where each vehicle interacts with only a few of its neighbors. We obtain explicit expressions for necessary conditions for stability in the cases that a system consists of a periodic arrangement of two or three different types of vehicles, i.e. configurations as follows: 2-1-2-1 or 3-2-1-3-2-1. Previous literature indicated that the (necessary) condition for stability in the case of a single vehicle type (1-1-1) held that the first moment of certain coefficients of the interactions between vehicles …

An Autoethnographic Self-Study Navigating The Transition To Becoming A Stem Teacher Educator, Miriam Hamilton Dr

The Qualitative Report

This paper reports on a self-study where I take an autoethnographic stance in narrating my cultural origins, trajectory and identities as a teacher turned teacher educator working in the field of education in Ireland. Using self-study, I explore how my habitus has influenced my experiences of being a biology teacher at second level to teaching STEM education on initial teacher education programmes. Autoethnographic self-study is the hybrid approach used to describe and systematically analyse my experiences and learning as I struggle with a transitioning identity. The integrated use of both self-study and autoethnographic approaches enabled a deepened understanding of my …

Teaching Challenging Texts And Encouraging Inquiry Remotely, Aisha Ratanapool

UNLV Best Teaching Practices Expo

Creating a culture of inquiry in non-research based courses helps students enhance their skills in critical thinking, reading, writing, collaboration, and argumentation. In English 101, some students feel like not having all of the answers about a text after a first read is unacceptable. This practice is designed to help college students understand and confidently discuss complex texts in a remote course.

Click Conjugation Of Boron Dipyrromethene (Bodipy) Fluorophores To Egfr-Targeting Linear And Cyclic Peptides, Tyrslai M. Williams, Nichole E.M. Kaufman, Zehua Zhou, Sitanshu S. Singh, Seetharama D. Jois, Maria Da Graça H. Vicente

Faculty Publications

Through a simple 1,3-cycloaddition reaction, three BODIPY-peptide conjugates that target the extracellular domain of the epidermal growth factor receptor (EGFR) were prepared and their ability for binding to EGFR was investigated. The peptide ligands K(N3)LARLLT and its cyclic analog cyclo(K(N3)larllt, previously shown to have high affinity for binding to the extracellular domain of EGFR, were conjugated to alkynyl-functionalized BODIPY dyes 1 and 2 via a copper-catalyzed click reaction. This reaction produced conjugates 3, 4, and 5 in high yields (70-82%). In vitro studies using human carcinoma HEp2 cells that overexpress EGFR demonstrated high cellular uptake, particularly for the cyclic peptide …

Self-Expanding Metal Stent (Sems) Placement To Treat Bleeding From Late Radiation Esophagitis, Inayat Gill, Bana Antonios, Zaid Imam, Gahad Ghaith

Articles

Radiation esophagitis is a serious complication occurring in patients receiving radiotherapy for head and neck cancers. Current treatment with proton pump inhibitors and mucosal protectants provides symptomatic relief with few studies showing improvement in erosive esophagitis or ulceration. Use of self-expandable metal stents (SEMS) in cases of erosive radiation esophagitis refractory to medical therapy has not been studied. We report a case of a patient presenting with recurrent hematemesis from late (chronic) radiation esophagitis with bleeding esophageal ulceration successfully treated with SEMS placement after failure of conservative medical management, proposing a possible utility for SEMS in this setting.

Parameter Estimation And Optimization For Biological Mathematical Models Using Bayesian Statistics, Renee Dale

LSU Master's Theses

In the field of biology, mathematical models are increasingly used to address biological questions and the large data sets generated in experimental studies. Mathematical models traditionally are simplified and structured to be analytically tractable, but computing power allows for more complex, larger models. Bayesian statistics lends itself naturally to address parameter estimation problems in these large models. Bayesian statistical inference is utilized in this thesis to obtain parameter estimates from a sparse data set on populations in the HIV epidemic. Current estimates of the HIV epidemic indicate a decrease in the incidence of the disease in the undiagnosed subpopulation over …

Predation Of Ananteris Spp. (Scorpiones: Buthidae) By Ants And A Social Wasp (Hymenoptera: Formicidae, Vespidae) In Panama, Central America, Roberto Miranda, Luis F. De Armas, Roberto A. Cambra

Euscorpius

Two events of predation on Ananteris spp. were observed in the Parque Nacional Darién, Darién Province, Panama. The first case involved the social wasp Agelaia centralis (Cameron, 1907) (Vespidae); the second one, a ponerine ant Leptogenys cf. cuneata Lattke, 2011 (Formicidae). This is the first time that predation by a social wasp on a scorpion is observed. They also represent the first recorded predators for Panamanian Ananteris species.

Effects Of A Large-Scale, Natural Sediment Deposition Event On Plant Cover In A Massachusetts Salt Marsh, Gregg E. Moore, David M. Burdick, Mike R. Routhier, A. B. Novak, Andrew R. Payne

Jackson Estuarine Laboratory

In mid-winter 2018, an unprecedented sediment deposition event occurred throughout portions of the Great Marsh in Massachusetts. Evaluation of this event in distinct marsh areas spanning three towns (Essex, Ipswich, and Newbury) revealed deposition covering 29.2 hectares with an average thickness of 30.1±2.1 mm measured shortly after deposition. While sediment deposition helps marshes survive sea level rise by building elevation, effects of such a large-scale deposition on New England marshes are unknown. This natural event provided an opportunity to study effects of large-scale sediment addition on plant cover and soil chemistry, with implications for marsh resilience. Sediment thickness did not …

Differential Expression Of Αvβ3 And Αvβ6 Integrins In Prostate Cancer Progression, Fabio Quaglia, Shiv Ram Krishn, Yanqing Wang, David W Goodrich, Peter Mccue, Andrew Kossenkov, Amy C Mandigo, Karen Knudsen, Paul H Weinreb, Eva Corey, William Kevin Kelly, Lucia R Languino

Department of Cancer Biology Faculty Papers

Neuroendocrine prostate cancer (NEPrCa) arises de novo or after accumulation of genomic alterations in pre-existing adenocarcinoma tumors in response to androgen deprivation therapies. We have provided evidence that small extracellular vesicles released by PrCa cells and containing the αVβ3 integrin promote neuroendocrine differentiation of PrCa in vivo and in vitro. Here, we examined αVβ3 integrin expression in three murine models carrying a deletion of PTEN (SKO), PTEN and RB1 (DKO), or PTEN, RB1 and TRP53 (TKO) genes in the prostatic epithelium; of these three models, the DKO and TKO tumors develop NEPrCa with a gene signature comparable to those of …
