Sars-Cov-2 Viral And Serological Testing When College Campuses Reopen: Some Practical Considerations, Isaac Chun-Hai Fung, Chi-Ngai Cheung, Andreas Handel

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

The coronavirus disease 2019 (COVID-19) pandemic prompted universities across the United States to close campuses in Spring 2020. Universities are deliberating whether, when, and how they should resume in-person instruction in Fall 2020. In this essay, we discuss some practical considerations for the use of 2 potentially useful control strategies based on testing: (1) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) testing followed by case-patient isolation and quarantine of close contacts, and (2) serological testing followed by an “immune shield” approach, that is, low social distancing requirements for seropositive persons. The isolation of case-patients and …

Epidemiology Of Cancers In Men Who Have Sex With Men (Msm): A Protocol For Umbrella Review Of Systematic Reviews, Manoj Kumar Honaryar, Yelena Tarasenko, Maribel Almonte, Vitaly Smelov

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

While earlier studies on men having sex with men (MSM) tended to examine infection-related cancers, an increasing number of studies have been focusing on effects of sexual orientation on other cancers and social and cultural causes for cancer disparities. As a type of tertiary research, this umbrella review (UR) aims to synthesize findings from existing review studies on the effects of sexual orientation on cancer. Relevant peer-reviewed systematic reviews (SRs) will be identified without date or language restrictions using MEDLINE, Cochrane Database of Systematic Reviews, and the International Prospective Register for Systematic Reviews, among others. The research team members will …

Laplacian Spectral Properties Of Signed Circular Caterpillars, Maurizio Brunetti

Theory & Applications of Graphs

A circular caterpillar of girth n is a graph such that the removal of all pendant vertices yields a cycle C_n of order n. A signed graph is a pair Γ =(G,σ), where G is a simple graph and σ: E(G) →{+1, -1} is the sign function defined on the set E(G) of edges of G. The signed graph Γ is said to be balanced if the number of negatively signed edges in each cycle is even, and it is said to be unbalanced otherwise. We determine some bounds for the first n Laplacian eigenvalues …

The Effects On Instructional Conversations On English Language Learners, Elizabeth Hendy, Joshua Cuevas Dr.

Georgia Educational Researcher

This research examined the effectiveness that the Instructional Conversations (ICs) teaching method had on elementary-aged English Language Learning (ELLs) students. Specifically, how ICs impact student academic achievement, academic language usage, and student engagement. The study compared two first grade classrooms, 39 participants, consisting of majority ELL students. The experimental group received math instruction through Instructional Conversation activities while the comparison group was taught using traditional math instruction and centers. After controlling for initial ability in math, results indicated that ICs did not lead to an increase of academic achievement or academic language usage when compared to students taught through traditional …

Campus Carry In Georgia: Challenges & Recommendations, Elizabeth Lohrmann, Carlie Cooper, Skyler Hooper, Ashley Washington, Zakia Williams-Sledge

Journal of Higher Education & Student Affairs

Abstract

The 2017 Georgia House Bill 280 states that, with limited exceptions, a properly licensed handgun owner can conceal carry on Georgia’s public college and university campuses. Since its inception and because of the recent history of mass shootings, much controversy surrounds this law. The infancy and controversy behind this law calls for further research into the subject. In this paper, we will offer a discussion of historical and environmental perspective, compliance with the law, risks and challenges, previous case analysis, and recommendations for Georgia Higher Education administrators. To lessen confusion and controversy surrounding the Campus Carry law in Georgia, …

It examines the extent to which students increase their ability to correctly solve word problems. It compares students’ attitudes toward mathematics problem solving before and after schema-based instruction. The study was conducted in a resource class with seven second-grade students on individualized education programs (IEPs). A single-subject research design was used. The schema-based instruction was implemented by the special education teacher in a small group setting. Students showed an increase in attempted and correct strategy use during …

Interpersonal Dynamics Of The Supervisory Triad Of Pre-Service Teacher Education: Lessons Learned From 15 Years Of Research, Anna Hart

Georgia Educational Researcher

Clinical field experience is recognized by many as the most influential and beneficial component of pre-service teacher education. The present article represents part of a larger qualitative meta-synthesis, the purpose of which was to explore the influence of the interpersonal dynamics of the supervisory triad—comprised of the pre-service teacher candidate, the mentor teacher, and the university supervisor—on pre-service candidates’ clinical experiences. Positioning theory was chosen to frame this investigation, as it employs distinct definitions for role and position, the delineation of which is of critical importance in the context of pre-service clinical relationships. Findings of the larger study reveal …

Evaluating The Importation Of Yellow Fever Cases Into China In 2016 And Strategies Used To Prevent And Control The Spread Of The Disease, Chao Li, Dan Li, Shirley Joann Smart, Lei Zhou, Peng Yang, Jianming Ou, Yi He, Ruiqi Ren, Tao Ma, Nijuan Xiang, Haitian Sui, Yali Wang, Jian Zhao, Chaonan Wang, Yeping Wang, Daxin Ni, Isaac Chun-Hai Fung, Dexin Li, Yangmu Huang, Qun Li

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

During the yellow fever epidemic in Angola in 2016, cases of yellow fever were reported in China for the first time. The 11 cases, all Chinese nationals returning from Angola, were identified in March and April 2016, one to two weeks after the peak of the Angolan epidemic. One patient died; the other 10 cases recovered after treatment. This paper reviews the epidemiological characteristics of the 11 yellow fever cases imported into China. It examines case detection and disease control and surveillance, and presents recommendations for further action to prevent additional importation of yellow fever into China.

Driving Reform Through Communities Of Practice In Scientific Fields, Amanda L. Glaze

Middle Grades & Secondary Education: Faculty Publications

Humans learn through social interactions therefore it is not surprising that we create around ourselves social structures that guide and support our learning as well as our practice. Communities of practice are one such social structure that exists within fields of science. Understanding the secondary cultures that are represented in the epistemology, practices, and perceptions of each field can help us better approach reform in fields using communities of practice as a starting point. The intersections of communities, culture, and change represent challenges to reform in education that should be explored and leveraged.

Wrack & Ruin: A Tale Of Tortured Trees, John T. Van Stan Ii, Albertus Tyasseta, Siloy, Graphic Artist

Earth, Environment & Sustainability: Faculty Bookshelf

Here, we visit a community of trees living along the Georgia coast, just above the high tide line, on a little lump of sand called a "hammock." This hammock plant community is battered by a hurricane. The plants that survive soon realize that they have fallen prey to a hydrological torture wrack - one composed of the salty corpses of their neighboring marsh plants (Spartina alterniflora). This sci comic is based on the publication, "Wrack and ruin: Legacy hydrologic effects of hurricane-deposited wrack..." (https://doi.org/10.1088/2515-7620/ab9527).

Wrack And Ruin: Legacy Hydrologic Effects Of Hurricane-Deposited Wrack On Hardwood-Hammock Coastal Islands, John T. Van Stan Ii, Scott T. Allen, Travis Swanson

Earth, Environment & Sustainability: Faculty Publications

Hurricanes can cause immediate catastrophic destruction of marsh vegetation and erosion of soils; however, they also have long-lasting ecological impacts. Those impacts include the deposition of tremendous amounts of saltmarsh litter ('wrack') onto upland ecosystems, the hydrologic effects of which have not previously been investigated. When Hurricane Irma battered the southeastern US coastline, widespread wrack deposition was reported (often exceeding 0.5 m depth), especially in vulnerable coastal hammock ecosystems: locally-elevated forests within the saltmarshes that rely on freshwater inputs from rain. We report the impacts of this deposited wrack, which has persisted for 2 years, on effective precipitation inputs to …

The Burning Number Of Directed Graphs: Bounds And Computational Complexity, Remie Janssen

Theory & Applications of Graphs

The burning number of a graph was recently introduced by Bonato et al. Although they mention that the burning number generalizes naturally to directed graphs, no further research on this has been done. Here, we introduce graph burning for directed graphs, and we study bounds for the corresponding burning number and the hardness of finding this number. We derive sharp bounds from simple algorithms and examples. The hardness question yields more surprising results: finding the burning number of a directed tree with one indegree-0 node is NP-hard, but FPT; however, it is W[2]-complete for DAGs. Finally, we give a fixed-parameter …

Top-level communities were coded into Community Types and were analyzed to surface trends in current practice. This presentation reviews trends in practice that emerged during research, as well as some of the best practices that were identified, including planning, iteration, labeling, limiting jargon, and finding a balance with top-level and nested content. Suggestions for improvement are given …

Radio Graceful Labelling Of Graphs, Laxman Saha, Alamgir Rahaman Basunia

Theory & Applications of Graphs

Radio labelling problem of graphs have their roots in communication problem known as Channel Assignment Problem. For a simple connected graph G=(V(G), E(G)), a radio labeling is a mapping f : V(G) →{0,1,2,…} such that |f(u)-f(v)|≥ diam(G)+1-d(u,v) for each pair of distinct vertices u,v ∈ V(G), where diam(G) is the diameter of G and d(u,v) is the distance between u and v. A radio labeling f of a graph G is a radio graceful labeling of G if f(V(G)) = {0,1,… |V(G)|-1}. A graph for which a radio graceful labeling exists is called radio graceful. …

On May 7, 2020, we identified the websites of the national health authorities of the G20 countries to identify naming of COVID-19 in their respective languages, and the websites of the health authorities in mainland China, Hong Kong, Macau, Taiwan and Singapore and identify their Chinese name for COVID-19. Among the G20 nations, Argentina, China, Italy, Japan, Mexico, Saudi Arabia and Turkey do …

Designing Peptides To Bind Kappa B Dna And Mimic Nf-Kappa B Protein Complexes, Nicholas A. Markowich

Honors College Theses

Transcription factors are important proteins that regulate gene expression and protein synthesis. Transcription factors can either boost the gene’s transcription rate by helping RNA polymerase activate transcription or restrict it by interfering with RNA polymerase, thereby repressing transcription. Nuclear factor-kappa-B (NF-κB) transcription factors are a family of proteins that control the synthesis of proteins involved in many cellular processes such as inflammatory and immune responses, cell growth, and apoptosis. However, the overexpression and activation of these transcription factors is linked to deadly conditions such as cancer and neurodegenerative diseases which currently have few safe cures. The goal of this research …

Domination Number Of Annulus Triangulations, Toshiki Abe, Junki Higa, Shin-Ichi Tokunaga

Theory & Applications of Graphs

An annulus triangulation G is a 2-connected plane graph with two disjoint faces f₁ and f₂ such that every face other than f₁ and f₂ are triangular, and that every vertex of G is contained in the boundary cycle of f₁ or f₂. In this paper, we prove that every annulus triangulation G with t vertices of degree 2 has a dominating set with cardinality at most ⌊ \frac{|V(G)|+t+1}{4} ⌋ if G is not isomorphic to the octahedron. In particular, this bound is best possible.

Replenishing Qualities Of Prayer, Morgan A. Kennon

Honors College Theses

Abstract

This study focused on the cognitive realm of self-control, which includes attention control and problem-solving. We used a challenging cognitive task to induce ego depletion, defined as the loss of self-control subsequent to exercising control. After removing students’ self-control in a laboratory setting, we tested whether prayer could possibly replenish lost self-control. Prior research has indicated that prayer may invoke self-control, and religious individuals report higher levels of self-control overall. Although prayer failed to return lost self-control in the current study, results provided additional support for a positive relationship between self-reported religiosity/spirituality and self-control.

Silicon Quantum Dots Conjunctive With Stable Radicals: Potential Application In Non-Invasive Cancer Diagnostics, Daylan R. Post

Honors College Theses

Quantum Dots, and nanomaterials in general, are one of the most promising areas of current physical study, especially their potential medical uses. In this study we introduced Nitroxide free radicals into a Silicon Quantum Dot (SiQD) solution and conducted experiments on the modified SiQDs in order to characterize their physical properties. We gathered emission, excitation, absorption and electron spin resonance (ESR) spectra of both modified and unmodified SiQDs. Previous studies have shown the possibility of using proteins as markers for cancer detection. Our measurements show the potential of using the interaction between these protein markers and SiQDs as a form …

Elementary & Special Education: Faculty Publications

There continues to be the global demand for a qualified workforce in science, technology, engineering and mathematics (STEM). Yet, for Black females in South Africa this means combating the legacy of Apartheid to overcome challenges due to race and gender. This paper draws data from a qualitative study of four Black South African females in STEM careers. Through their voices they identify ways in which they transgress gender and race to gain access to STEM careers. Further, their families transgress cultural norms in order to offer support for unfamiliar career pathways. Their narratives call for a transformative change in higher …

Some Asymptotic Properties Of Seirs Models Withnonlinear Incidence And Random Delays, Divine Wanduku, Broderick O. Oluyede

Mathematical Sciences: Faculty Publications

This paper presents the dynamics of mosquitoes and humans with general nonlinear incidence rate and multiple distributed delays for the disease. The model is a SEIRS system of delay differential equations. The normalized dimensionless version is derived; analytical techniques are applied to find conditions for deterministic extinction and permanence of disease. The BRN R0* and ESPR E(e–(μvT1+μT2)) are computed. Conditions for deterministic extinction and permanence are expressed in terms of R0* and E(e–(μvT1+μT2)) and applied to a P. vivax malaria scenario. Numerical results are given.
