Early Adolescent Social Isolation, Hope, And Well-Being During A Pandemic, Alicen Hauck
Early Adolescent Social Isolation, Hope, And Well-Being During A Pandemic, Alicen Hauck
Electronic Theses and Dissertations
Social isolation is often divided into two subcategories of objective and subjective. The COVID-19 pandemic has led to an increase in objective social isolation in the form of social distancing and fewer social events. Research delineating the relationship between social isolation and adolescent well-being utilize measures of subjective social isolation. Whereas, measures of objective social isolation are more commonly used with geriatric populations. Therefore, there is a lack of information specific to the impact of objective social isolation on adolescent well-being, particularly during a pandemic. The effects of social isolation due to COVID-19 will not be short lived. Deciphering the …

Technology-Based Culturally Relevant Chemistry Education (Crce), Mercy Adoma Fosu
Electronic Theses and Dissertations
The relevance of chemistry concepts and principles remains a challenge for most students enrolled in college chemistry courses. Part of this problem is the disconnect with what students experience in their every-day lives, and how the material, specifically chemistry content is presented via textbooks, lectures, and laboratory teaching. Moreover, the teaching of general chemistry has traditionally focused on traditional, instructor-centric expository delivery of course materials, that treats students as empty vessels devoid of prior knowledge. Students prior knowledge and experiences are crucial in shaping their understanding of scientific concepts and principles. Even students with relatively low expectations for success in …

Developing Microbial Based Process To Produce High Value Natural Antimicrobial (Glyceollin) In Soybeans And Pullulan From Sucrose, Andrea Zavadil
Electronic Theses and Dissertations
Glyceollin is a secondary metabolite produced under stress conditions by soybean to act as a plant defender to pathogen attack. The antimicrobial nature of glyceollin makes it a promising natural alternative to antibiotics if incorporated into livestock feed. However, production of glyceollin is highly variable, dependent on soybean variety, and fungal elicitor used as inoculum. Our study compares two fungal spore elicitors, Trichoderma reesei and Aspergillus sojae on soybeans of diverse maturity level, and fungal susceptibility to determine highest glyceollin titer. Spore inoculation with T. reesei elicited highest glyceollin titers of 2.42±0.20 mg/g at 120 h, while A. sojae elicited …

Vicarious Methodologies To Assess And Improve The Quality Of The Optical Remote Sensing Images: A Critical Review, Sakib Kabir
Electronic Theses and Dissertations
Over the past decade, number of optical Earth observing satellites performing remote sensing has increased substantially, dramatically increasing the capability to monitor the Earth. The quantity of remote sensing satellite increase is primarily driven by improved technology, miniaturization of components, reduced manufacturing, and launch cost. These satellites often lack on-board calibrators that a large satellite utilizes to ensure high quality (e.g., radiometric, geometric, spatial quality, etc.) scientific measurement. To address this issue, this work presents “best” vicarious image quality assessment and improvement techniques for those kinds of optical satellites which lacks on-board calibration system. In this article, image quality categories …

Examining Instructional Methods In End-Of-Life Nursing Education: Lecture Vs. Simulation, Jonathan M. Benson
Electronic Theses and Dissertations
Undergraduate nursing programs have historically glossed over end-of-life care, if their curricula addressed it at all. This lack of instruction can leave practicing nurses feeling poorly prepared to deliver this specialized care. Feeling incompetent and lacking confidence may lead to poorer attitudes regarding this nursing specialty. Thus, effective continuing education activities are paramount in equipping nurses to provide this care and improve attitudes towards caring for terminally ill patients and their families. The purpose of this study was to examine how registered nurse attitudes towards end-of-life care are impacted using a simulation-based learning experience compared to a traditional face-to-face lecture …

Do These Violent Delights Have Violent Ends? Social Norms, Alcohol, & Sexual Cyberbullying, Anandi C. Ehman
Electronic Theses and Dissertations
Sexually aggressive behavior is well-documented among college students. However, little is known about the role technology may play in facilitating this behavior. Given that social norms have been established as a useful framework for understanding problematic and risky behavior in college students, the current authors sought to determine whether this theory might also provide insight into the use of technology to facilitate sexually aggressive behavior. Thus, this work sought to determine whether sexually aggressive behavior which occurs through the use of technology and social media, henceforth known as sexual cyberbullying, mediated the relationship between perceived social norms of sexually aggressive …
Understanding Social Anxiety Symptoms Through Interpersonal Emotion Regulation Strategies, Megan Perry
Understanding Social Anxiety Symptoms Through Interpersonal Emotion Regulation Strategies, Megan Perry
Electronic Theses and Dissertations
Social anxiety disorder (SAD) is one of the most prevalent and chronic psychological disorders among college students. Previous literature has shown that emotion regulation (ER) difficulties are relevant to the maintenance and aggravation of SAD. Within SAD, ER research has exclusively explored intrapersonal (within person) ER difficulties. However, interpersonal (between two or more people) ER difficulties have not been explored as a potential factor contributing to the intensity of social anxiety symptoms. Therefore, the aim of the current study was to examine the use of interpersonal ER strategies in SAD symptoms among college students. In the current study, students in …

Awareness Of Peace Journalism Among Bangladeshi And Ethiopian Journalists, Sima Rani Bhowmik
Electronic Theses and Dissertations
News is a vital element to keep people informed. Though the orientation of the stories is often debated over whether it is based on facts or lies. In a polarized society, it may not be the event that contributes to violence, but how the event is reported. Here is where the role of peace journalism comes in where reporters or news managers can shed light on structural and cultural causes of violence. It is in this context that this study attempted to investigate the level of awareness of peace journalism among Bangladeshi and Ethiopian journalists. To this end, the researcher …
Holding Space: Learning From A Black Art Organization, Tierney Anne Bamrick
Holding Space: Learning From A Black Art Organization, Tierney Anne Bamrick
Electronic Theses and Dissertations
Minority-led nonprofit organizations are marginalized in the United States arts sector, analyses of which rely heavily on data from dominant, often White-led institutional arts organizations. This study seeks to understand the experience of a minority-led arts organization in that context. I ask, what does artistic practice – both creative and organizational – look like for this organization? And what are the implications of that practice for the arts sector more broadly? Drawing on over a year of ethnographic work with The Network, a Black-led arts organization in a southern U.S. city, I argue that their asset-focused treatment of place, their …

Application Of Nanofiltration To Delactosed Permeate To Produce Food Grade Retentate And Permeate Streams, Lee Alexander
Electronic Theses and Dissertations
Delactosed permeate (DLP), commonly referred to as mother liquor, is a plentiful byproduct in the dairy industry. It is a direct byproduct of edible lactose manufacture produced in cheese and dairy ingredient facilities. Despite being rich in lactose and minerals, DLP is most commonly relegated to an animal feed product due to its high ash content, it inhibits and disallows crystallization of any remaining lactose. Delactosed permeate showed many inconsistencies from supplier to supplier and within lots from the same supplier in the eight DLP samples obtained from four separate mozzarella and cheddar manufacturing facilities. Nanofiltration (NF) opens potential food …

Analysis Of Coevolving Residues Of Xcdxcdx-Phd, A Distinct Type Of Phd-Finger, Shraddha Basu
Electronic Theses and Dissertations
Plant homeodomain (PHD), a Zinc-finger scaffold, is a conserved protein module in eukaryotes that typically recognizes unstructured histone tails, and thus, PHDs play a crucial role in chromatin signaling. The sequences of Zinc-fingers, in general, diversify during the course of evolution often giving rise to subtypes (e.g., RBR-RING (Dove 2017) or zf-CxxC subtypes (Long 2013) who typically contain specific sequence signatures. We recently discovered that PHD fingers also contain a distinct subtype, namely the xCDxCDx-PHD. xCDxCDx-PHD has a distinct composition of specific amino acids that coevolved (coevolving residues) in the course of evolution, and xCDxCDx-PHD also shows a unique mechanism …
Evaluation Of Processing Variables To Increase The Solids Of Milk Protein Concentrates Prior To Drying, Achyut Mishra
Evaluation Of Processing Variables To Increase The Solids Of Milk Protein Concentrates Prior To Drying, Achyut Mishra
Electronic Theses and Dissertations
It is a common practice in dairy industries to nanofilter milk protein concentrate (MPC) to increase the solids and further drying efficiency. Increasing protein and solids in MPC increases viscosity and resist feed-flow in membrane filtration. Previous research proved that increased temperature and hydrodynamic cavitation (HC) have significantly reduced the viscosity of MPC which can potentially increase the level of solids by reducing concentration polarization during nanofiltration (NF). We utilized plate and frame filtration (PF) as an alternate method to reduce the viscosity of MPC. In first objective, we studied the application of HC or elevated temperature (50˚C) or both …
