Supporting Dining Occupations For Dementia Residents In Skilled Nursing Facilities, Esther Yu, Nooshin Moslehi, Vickie Nguyen, Aileen Quach, Cierra Passey, Julia Lee

Occupational Therapy | MSOT Capstone Projects

Dementia Friendly Dining provides skilled nursing facilities (SNFs) with a practice guideline and training resources for caregivers. The program is informed by existing research on environmental modifications, both physical and social, to enhance the occupations of feeding, eating, and dining for individuals with dementia (IwD) in SNF settings. The physical and social environment has a significant effect in supporting the dining experience for IwD and their caregivers (Keller et al., 2015; Hung et al, 2016; Palese et al., 2018), but many facilities have not integrated physical and social modifications, creating a gap in practice. Therefore, an evidence-based dining program that …

The Effect Of Egcg-P Containing Formulations On Bacillus Spp., Sabrina A. Lopez

Seton Hall University Dissertations and Theses (ETDs)

The Gram-positive Bacillus species is known for their spore-forming abilities. These spores are highly resistant to a multitude of factors such as heat, UV radiation, and chemical solvents, which can be attributed to the location of its DNA, and other components that make up the spore as a whole. Bacillus spp. can be detrimental to the food & beverage industry and the medical field due to their production of enterotoxins, which can manifest as bacterial infections. Antibiotic-resistant bacteria towards current treatments are of major concern, and thus the need for alternative therapeutic agents is urgent. The beneficial health properties of …

Nursing Perceptions And Attitudes Toward Sex Trafficking: Does Victim Gender Matter?, Sarah Rapoza

Dissertations

Sex trafficking (ST) often goes unrecognized; yet, it is a pervasive issue that disproportionately affects marginalized populations. Sex trafficking involves the act of recruiting, transporting, transferring, harboring, or receiving of persons for the purpose of commercial sex acts. As a result of ST, victims suffer adverse health effects and often present to healthcare facilities while still under control of their traffickers. Few healthcare personnel are aware trafficking is happening in their geographical areas and victims are rarely identified or offered assistance. The majority of studies and interventions related to ST focus on female victims despite evidence that males are also …

Women And The Superintendency, Jennifer Carol Perry

Dissertations

The purpose of this study was to determine whether past and present female superintendents in Colorado felt their career paths were gendered. In addition, what strategies they used to navigate their experiences were examined. A qualitative multi-case study design was used to structure this study. A social constructionism philosophy as described by Crotty (2003) guided the study. The multi-case design and epistemology support collecting multiple experiences within a phenomenon (Crotty, 2003). Participants were selected through purposeful snowball sampling. The community of female superintendents in Colorado is small and connected. This study included four retired female superintendents and five who are …

From Self-Sufficiency To Import Dependence In The Republic Of The Marshall Islands: Data Issues And Challenges, Debra L. Claypool

Electronic Theses, Projects, and Dissertations

Although it appears likely that the profoundly asymmetrical political and economic relationship between the United States and the Republic of the Marshall Islands (RMI) has contributed to the abandonment of traditional agriculture, import-dependency, and a decrease in quality of life for the citizens of the RMI, limits in existing quantitative data make it impossible to model exactly how this occurred. Therefore, rather than seek to model this causal relationship, the researcher employed three existing ethnographic studies to establish a quantitative measure of the transformation itself. Using additional government documents to supplement the existing data, a measure of relative percentage of …

Effects Of Neonatal Ethanol Exposure In Normal And Dopamine Deficient Rats, Jessica Luz Razo

Electronic Theses, Projects, and Dissertations

Attention deficit hyperactivity disorder (ADHD) is a common developmental disorder characterized by impulsivity, inattention, and hyperactivity. In rodents, neonatal 6-OHDA lesions is an established model of ADHD because it produces symptoms of hyperactivity and cognitive deficits that improve following psychostimulant treatment. Recently, early alcohol exposure in rodents has also been suggested as a model of ADHD due to the high prevalence of ADHD in children exposed prenatally to alcohol. However, children exposed to prenatal alcohol differ in symptoms from children with idiopathic ADHD, suggesting that ADHD caused by prenatal alcohol exposure may be a special subtype of ADHD or a …

Are School Lunches Contributing To The Obesity Epidemic Among Children?, Luis Chavez

Electronic Theses, Projects, and Dissertations

Background: Childhood obesity is a major public health issue in the United States (U.S.) and recent data have shown that the incidence and prevalence have been increasing over the past 20 years. Poor dietary habits are often attributed to these increasing rates. The National School Lunch Program (NSLP) provides meals and snacks to over 30 million students. Therefore, determining whether an association exists between student participation in the NSLP, and their respective body mass index (BMI) is critical. Few studies have examined a family’s economic stability and the child’s race as potential moderating variables. This study aimed to investigate …

Evaluation Of Α-Pyrrolidindovalerophenone (Α-Pvp) And Its Isomers In Male And Female Sprague-Dawley Rats Trained To Discriminate Mdpv, Kaley Cargile

Masters Theses

Recreational use of synthetic cathinones, 3,4-methylenedioxypyrovalerone (MDPV) and α‐pyrrolidinovalerophenone (α‐PVP), has become increasingly popular, thus prompting characterization of their behavioral and neurochemical effects. MDPV has been studied for several years now, though there is still much unknown about α‐PVP, and its isomers. The primary objective of this study was to characterize the discriminative effects of α‐PVP and its isomers in comparison to MDPV. Male and female Sprague-Dawley rats were trained to discriminate 0.5mg/kg MDPV from saline injections under a fixed ratio 20 (FR 20) schedule of food reinforcement. Substitution tests were conducted with MDPV (0.05-0.5mg/kg), α‐PVP (0.05-0.5mg/kg), (S)-α‐PVP (0.05-1mg/kg) and …
