Third-Person Perception As A Mediator Of The Influence Of Social Networking Sites Use And Personal Relevance To Preventive Behavioural Intention, Joseph Edwin, Ummi Salamah

JURNAL KOMUNIKASI INDONESIA

News coverage on Covid-19 is important as it provides people with important updates as well as crucial information for avoiding infection. Previous studies have shown undesirable messages such as Covid-19 news that circulates in social networking sites can trigger ‘third-person perception (TPP)’, which is a phenomenon in which audiences presume a message exerts more influence upon people other than themselves. It is crucial to examine whether audiences experience TPP during consumption of pandemic news – especially when there is a possible negative correlation between TPP and protective behavioural intentions. Previous studies showed empirical evidence when users used Covid-19 news in …

Some review papers have discussed inactivation efficacies of different treatments against B. cereus, but they are narrative without quantitative summaries. This study first aimed to find effective and food industry-applicable treatment candidates against B. cereus spores and biofilms by synthesizing and comparing the efficacy of treatments using systematic review and meta-analysis. After screening, 17 studies were included, but only nine studies were used for meta-analysis …

“Practice Basic Hygiene, And You’Ll Stay Healthy”: How Primary School Reading Textbooks Transmitted Cultural Education In The Soviet Union, Victoria Storozenko

University of South Florida (USF) M3 Publishing

Russia’s Cultural Revolution, beginning after the October Revolution in 1917, produced a broadly defined understanding of culture and cultural education at Russian schools that encompassed even basic hygiene and health. Drawing from postdoctoral research, this paper discusses the Cultural Revolution’s impact and its ideas on cultural education as presented in textbooks for 10-year general education schools in the Soviet Union. Discourse analysis revealed that the schoolbooks acted as an interface between a functional education system and changes in its surrounding environment, especially changes due to the Cultural Revolution. Amid today’s COVID-19 pandemic, the study’s findings raise several questions about what …

Background Flow Influence On Impulsive Jet-Driven Micro Droplet Dispersal, Vaishak Thiruvenkitam

Doctoral Dissertations and Master's Theses

Accurately predicting the airborne spread of infectious diseases is crucial in controlling the COVID­19 pandemic today. Studies have shown the spread of expiratory droplets depends on ambient thermodynamic conditions and flow properties of the jet emitted by the activity. However, the droplet spread in conditions of background flow is not yet comprehensively understood. This study uses the Eulerian­-Lagrangian model with k−ω turbulence modelling to simulate spread of particles and study the factors affecting it in a closed environment with a background flow. Respiratory activities are modeled as a non-­isothermal jet of air with droplets suspended in them in a predetermined …

One Child Town: The Health Care Exceptionalism Case Against Agglomeration Economies, Elizabeth Weeks

Utah Law Review

This Article offers an extended rebuttal to the suggestion to move residents away from dying communities to places with greater economic promise. Rural America, arguably, is one of those dying places. A host of strategies aim to shore up those communities and make them more economically viable. But one might ask, “Why bother?” In a similar vein, David Schleicher’s provocative 2017 Yale Law Journal article, Stuck! The Law and Economics of Residential Stagnation, recommended dismantling a host of state and local government laws that operate as barriers to migration by Americans from failing economies to robust agglomeration economies. But Schleicher …

Characterizing Bacterial Communities Across A Nutrient Gradient Over Winter Months, Emily Jin Searles Stone

Theses, Dissertations and Culminating Projects

When trying to understand how anthropogenic activities affect patterns in community ecology, bacterial communities are frequently neglected. These bacterial communities are essential to the overall health and stability of several different ecosystems. As nutrient pollution increases, some bacterial taxa may increase, causing an imbalance in food web dynamics and disrupting biogeochemical cycles. Next-generation sequencing coupled with water chemistry measurements has allowed for association testing between site water characteristics and bacterial taxa. By examining bacteria along a natural nutrient gradient over winter months in Overpeck Creek in northern New Jersey, this research shows that anthropogenic activities, specifically nutrient pollution, can alter …

"When The Voices Of Children Are Heard": Evaluating The Biological Effects Of Socioeconomic Status On Children In Postmedieval London., Ashley R. Ezzo

Electronic Theses and Dissertations

As the most vulnerable members of society, children (and their treatment) may reveal important sociocultural and socioeconomic praxes throughout human history. During the Postmedieval period, children, especially low socioeconomic status (SES) individuals, participated in the workforce. By examining the demographic distributions and paleopathological profiles of juvenile skeletal remains from high SES (St. Bride’s Crypt and Chelsea Old Church) and low SES (St. Bride’s Lower and Crossbones) Postmedieval (1700-1850 CE) London cemeteries, we can better understand how SES impacted the biological health and mortality of children. While results indicated higher mortality risk associated with low SES circumstances, most differences in pathological …

Development Of 3d-Bioprinted Scaffolds For Oral Probiotic Application., Jhanvi Patel

Electronic Theses and Dissertations

Background: Porphyromonas gingivalis adheres to and invades gingival epithelial cells, resulting in decreased cell viability. Previous studies have indicated that probiotics are effective against dental pathogens; however, few approaches provide sustained-delivery of active agents in the oral cavity. Hypothesis: Probiotics will limit P. gingivalis effects on Telomerase Immortalized Gingival Keratinocyte (TIGK) cells and 3D-printed scaffolds will prolong probiotic release. Methods: Lactobacillus acidophilus, Lactobacillus reuteri, and Bifidobacterium bifidum were assessed with adhesion and antibiotic protection assays to limit P. gingivalis effects on TIGKs. Scaffolds were printed with a select probiotic and evaluated for release kinetics. Results: Free L.a., …

Effect Of Lactoferrin To Increase Drug Permeability Of Primary Pulmonary Mycobacterial Granulomas, Thao Nguyen, Thao Kt Nguyen

Dissertations and Theses (Open Access)

Despite extensive research and worldwide eradication efforts, Mycobacterium tuberculosis (Mtb) remains a major infectious pathogen to the human population with about 10 million cases of infection per year globally. The host-pathogen interaction, pulmonary granuloma formation, and Mtb adaptions result in increased complexity of the disease. Granulomas are formed by active immune responses generated during Mtb infection, and serve to contain and limit bacterial dissemination. The major mycobacterial surface mycolic acid, trehalose 6,6'-dimycolate (TDM), functions in multiple ways to enhance immune cell recruitment of sites of infection, to induce inflammation and granulomatous responses, and to initiate survival strategies for …

Host Cell Responses To Zika Virus Infection, Bikash Ranjan Sahoo

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The re-emergence of Zika virus (ZIKV) in 2015 as a significant human pathogen causing neurological diseases in infants as well as adults is a serious global health concern. A clear understanding of the mechanisms involved in ZIKV replication in infected host cells as well as the host responses to virus infection are keys to the development of therapeutic strategies against ZIKV. Studies conducted in this dissertation demonstrate that ZIKV infection induces the activation of mTOR signaling cascade that promotes viral protein accumulation and infectious progeny production. While both mTORC1 and mTORC2 are essential for ZIKV replication, the observation that depletion …

Nicarbazin As An Oral Contraceptive In Eared Doves, Lourdes Olivera, Silvia Pereyra, Georgget Banchero, Guillermo Tellechea, Jorge Sawchik, Michael L. Avery, Ethel Rodríguez

United States Department of Agriculture Wildlife Services: Staff Publications

Eared doves (Zenaida auriculata) are responsible for substantial losses in cereal and oil crops as well as in dairy and feedlot production in the southern cone of South America. Various strategies have been shown to be effective in reducing damage at the farm scale, but in some scenarios, it is necessary to also incorporate population control methods due to excessive bird population size. An alternative approach to reduce pest bird populations is the use of contraceptive methods, minimizing the impact on the environment and non-target populations. Nicarbazin is registered in the United States as a contraceptive for Branta …

Teacher Stress Sources, Manifestations, And Coping Self-Efficacy During The Covid-19 Pandemic, Amanda S. Locke-Bayer

Education Doctoral

The purpose of this cross-sectional quantitative study was to examine the stress sources, stress manifestations, and coping efficacy of K–12 teachers during COVID-19 with a sample of 220 K–12 teachers in New York State. Chronic exposure to stress can lead teachers to experience poor emotional and physical health, causing them to often exit the field of education. In addition, the effects of teacher stress can create a tremendous financial burden on school districts and negatively influence learning environments for students. The results of this study suggest that K–12 teachers with high levels of time management stress reported decreased confidence in …

Multi-Scale And Multi-Group Modeling Techniques Applied To Cholera And Covid-19, Conrad Ratchford

Masters Theses and Doctoral Dissertations

Cholera is an acute intestinal illness caused by infection with the Vibrio cholerae bacteria. The dynamics of the disease transmission are governed by human-human, environment-human, and within-human sub-dynamics. Specifically, the within-host dynamics incorporate virus and immune cell interaction with the vibrios. One model is presented to incorporate all three of these dynamical components. This model is extended to consider the case of a sub-divided population interacting in a spatially heterogeneous environment. In particular, we find that the between-host reproduction number is shaped by the collection of the disease risk factors from all the individual host groups. These multi-patch techniques are …
