Social Bonding In Social Isolation: Social And Religious Support For Substance Use Recovery During Covid-19, Lindsey Chapman

All Theses

The importance of social bonds in supporting those in substance use recovery is illustrious through applications of social bonding theory. However, the effect of COVID-19 restrictions on these essential relationships has not been widely studied. The initial survey instrument studying social support, religious support, and substance use patterns before, during, and after COVID-19 was met with methodological difficulty in reaching the target population through email. This instrument was adapted into a semi-structured interview guide and methodology evolved to include participation either in-person or over Zoom. Through 14 in-depth interviews with people in substance use recovery programs, themes of isolation, peer …

Photonic integrated circuits (PICs) have significant value in today’s world of research. They enable devices to experience large reductions in size, weight, operation power, and cost (SWAPc), making photonic technology more accessible than ever. The functionality of PICs is greatly enhanced due to the realization of both active and passive devices within a single device structure. This is made possible through hybrid integration, which utilizes various coupling methods to transfer light from an active chip to a passive chip. Hybrid integration technology tremendously expands the capabilities of PICs, leading to a plethora of applications. One significant application is that of …

Augmented Human Inspired Phase Variable Using A Canonical Dynamical System, Timothy Driscoll

All Theses

Accurately parameterizing human gait is highly important in the continued development of assistive robotics, including but not limited to lower limb prostheses and exoskeletons. Previous studies introduce the idea of time-invariant real-time gait parameterization via human-inspired phase variables. The phase represents the location or percent of the gait cycle the user has progressed through. This thesis proposes an alternative approach for determining the gait phase leveraging previous methods and a canonical dynamical system.

Human subject experiments demonstrate the ability to accurately produce a phase variable corresponding to the human gait progression for various walking configurations. Configurations include changes in incline …

The survey used in the study was developed using the guidelines for making historic buildings accessible as described in the Americans with Disabilities Act and the Uniform Federal Accessibility Standards. It was distributed by email to representatives of 220 historic sites, of …

Measurement Of Microplastics In A Freshwater Micro-Watershed, Cole Bowman

All Theses

The role of microplastics as an emerging contaminant can be complex to study because of the lack of standardization in the collection and analysis of microplastic particles. The purpose of this manuscript is to detail an iterative process of different collection methods in trying to understand microplastic deposition and transport in a freshwater micro-watershed through lab-based and field-based studies. A flume experiment was conducted to test the trapping efficiency of a sediment trap design at two different velocities (1.12 m/s and 2.24 m/s). Eight types of microplastics varying in morphology and density were introduced to the flume in order to …

Survey And Prevalence Of Palmer Amaranth Herbicide Resistance In South Carolina, Mitchell Williams

All Theses

Palmer amaranth is a troublesome weed for growers to control, not only due to its aggressive growth characteristics that limit row-crop production, but because of its resistance to different herbicide modes of action. The first case of herbicide resistance in Palmer amaranth was detected in 1989 and has since grown to nine different herbicide classes throughout the United States. New herbicide modes of action have not been developed since the 1980s, so proper stewardship of the remaining modes of action is important for effective control of Palmer amaranth. Increased herbicide resistance from states bordering South Carolina have been reported; therefore, …

2020-Current year OA Pubs

Although pathogenic variants in PSEN1 leading to autosomal-dominant Alzheimer disease (ADAD) are highly penetrant, substantial interindividual variability in the rates of cognitive decline and biomarker change are observed in ADAD. We hypothesized that this interindividual variability may be associated with the location of the pathogenic variant within PSEN1. PSEN1 pathogenic variant carriers participating in the Dominantly Inherited Alzheimer Network (DIAN) observational study were grouped based on whether the underlying variant affects a transmembrane (TM) or cytoplasmic (CY) protein domain within PSEN1. CY and TM carriers and variant non-carriers (NC) who completed clinical evaluation, multimodal neuroimaging, and lumbar puncture for collection …

Don't Look Back And Spray! Risk Of Endoscope Adhesion With Hemospray Application In Retroflexion In A Pediatric Patient., Sarah T. Edwards, Diana G. Lerner, Moises Alatorre-Jimenez, Thomas M. Attard

Manuscripts, Articles, Book Chapters and Other Papers

Although the vast majority of recognized pediatric upper gastrointestinal bleeding (GIB) resolves spontaneously, gastrointestinal hemorrhage is the most common indication for urgent or emergent therapeutic endoscopy in pediatric practice. The application of hemostatic powders, including TC-325 (Hemospray, Cook Medical, Winston-Salem, NC, USA), has shown considerable impact on the control of acute bleeding, with the advantage of potentially covering an extensive area and requiring less technical expertise. We report a case of transient adherence of an esophagogastroduodenoscopy following Hemospray application in a 22-month-old with upper GIB. Our experience does not detract from the significant gains in the management of pediatric GIB …

Bankers As Immoral? Some Parallels And Differences Between Aquinas’S Views On Usury And Marxian Views Of Banking And Credit, Thomas E. Lambert

Faculty and Staff Scholarship

Since ancient times the practices and ethics of bankers and banking in general have undergone a great deal of criticism. While lending is motivated by profit, and while households are not explicitly coerced into borrowing money, the justice of a system which exploits workers and at the same time encourages them to borrow money in order to maintain a certain standard of living can be viewed as sometimes unfair and perhaps immoral. The value of goods, according to St. Thomas Aquinas and Karl Marx, should mostly reflect the value of labor embodied in them, and for that reason, labor should …

Is Neo-Fascism Inevitable? Looking At The Economic Surplus, The Baran Ratio, And Long Wave Cycles, Thomas E. Lambert

Faculty and Staff Scholarship

This paper briefly outlines the idea and development of the economic surplus concept at the macroeconomic level as opposed to the one in microeconomics often labeled as a Marshallian surplus. The notion of a residual amount of output or income over and above what is necessary for a society’s consumption (education, housing, food, clothing, health care, transportation, and other necessities of life) that can be used either for further consumption by an elite class, used for reinvestment in productive activities, and/or wasted on unproductive efforts is one that has been and continues to be taught and used in heterodox and …

Strategy-Specific Differentiation In Response To Resources And Drivers Of Spring Migration Phenology In Rocky Mountain Elk, Storm Crews

Theses

Elk (Cervus canadensis) are known to exhibit high movement strategy diversity compared to other ungulate species. Most elk populations are migratory or partially migratory, presenting unique conservation and management challenges. For example, successful maintenance of multiple seasonal ranges and connectivity between them is necessary to conserve populations with migratory behaviors. Further study of the structure and maintenance of movement strategy diversity within partially migratory populations is needed to assist management and refine fundamental ecological theory. Improved understanding of the determinants of elk migratory timing is also important, with the dynamics of significant drivers likely to shift under future climate change …

Comparing Stand Composition And Floristic Quality Of Two Adjacent Upland Oak-Hickory Woodlands In Southern Illinois: Old-Growth And Second-Growth Dynamics, Leah Rose Kleiman

Theses

Illinois has no official parameters for old-growth oak-hickory (Quercus-Carya) forests despite oak-hickory being the historically dominant ecosystem in the forested parts of Illinois (Fralish, 1997; Thompson & Dessecker, 1997). The purpose of this study was to better understand the characteristics of old-growth oak-hickory stands, as well as make management recommendations for preserving the integrity of old-growth forests and shifting second-growth stands to old-growth status. Stand structure analysis was conducted in June and July of 2022 on an old-growth oak-hickory stand (Otey-Grisley Nature Preserve) and nearby second-growth oak-hickory stand (Grisley Woods Land and Water Reserve) near Pittsburg, Illinois using dendrochronology, various …

Differential Movement Response Of Silver Carp To Individual And Environmental Conditions In The Illinois And Wabash Rivers, Taylor Mogavero

Theses

Knowledge about the spatial dynamics of invasive species is essential to predict, restrict, and prevent their spread to new areas. Invasive Silver Carp (Hypophthalmichthys molitrix) populations are expanding on all fronts and are threatening to establish in the Laurentian Great Lakes. Understanding their movement patterns is vital to prevent their populations from spreading further and to improve management efficiency. This study looked at multiple factors to understand which have an influence on the movement of invasive Silver Carp in two different river systems. Chapter 1 examined the relationship between individual and environmental factors—including length, body condition, temperature, and discharge—and movement …

Comparing Various Staff Training Modalities Within Applied Behavior Analysis, Jason Joseph Starr

Theses

Behavioral skills training (BST) has continuously demonstrated to be an effective means of training others in new skills and techniques. A limitation of BST, however, is that it requires extensive time and a professional trainer. Currently, there is a lack of literature comparing BST to alternative and effective training methods that require less resources, such as written directions and video modeling. Therefore, the purpose of this study was to determine which training modality (i.e., behavior skills training, written directions, or video modeling) was most effective at increasing staff members' correct implementation of applied behavior analysis procedures, specifically forward chaining, shaping, …

Educating Health Care Professionals On Implantable Hearing Solutions To Increase Appropriate Referral Rates In Adults, Hailey Lynn Guyette

Doctoral Scholarly Projects & Capstones

Despite being an available hearing treatment option for several decades, there is still an underutilization of cochlear implants within the population of adults with hearing loss that would meet candidacy criteria. Only 8% of people that are cochlear implant candidates utilize cochlear implants. Thus, it is important to examine why underutilization occurs and how to solve the problem. The current doctoral scholarly project aims to educate health care professionals, with targeted audiences of hearing instrument specialists and primary care practitioners, on cochlear implants, outcomes, and candidacy. Narrated PowerPoint presentation videos were created as a way to educate health care professionals …

Double Tense Marking In L1 Spanish Speakers/L2 English Learners, Vianney Zuniga

Open Access Theses & Dissertations

The present study examines the effects of Form Focused Instruction plus corrective feedback on "double-tense marking" (Al-Makatrah et al. ,2017; Cancino et al. 1967) in past tense negative statements and wh-questions among advanced L2 English speakers (Candry, 2013). These are learners who have reached the fourth stage of sentential negation, having acquired the auxiliary "do" and inflecting it in the past tense producing "did". Some advanced L1 Spanish speaking English learners inflect the verbs in structures in which the auxiliary "do" is already inflected for the past tense as in:

1. "I didn't knew about chemistry"

2. "When did he …
