Hotel Staycationers' Well-Being Perception, Satisfaction, And Loyalty: The Role Of Restorative Qualities And Service Quality, Chanmi Hong

Electronic Theses and Dissertations

During the COVID-19 pandemic, a rising trend for travelers is to stay at a local hotel, known as "hotel staycations," rather than traveling outside of their area. Despite the increasing popularity, empirical studies on customer behavior in the hotel staycation context are limited. Furthermore, existing studies have largely overlooked restorative qualities and service quality of hotel staycations, which can significantly influence customer well-being and satisfaction. To address these gaps, this study aims to examine the impact of restorative qualities and service quality on customers' perception of well-being and satisfaction with the hotel staycation experience by extending Kaplan's (1995) attention restorative …

Abstract: There is a growing body of evidence that inadequate maternal nutrition during gestation can have immediate and lifelong effects on offspring. However, little is known about the effects of maternal nutrition during gestation on male offspring reproduction. Here, using a sheep model of maternal restricted - and over - nutrition (60 or …

Sodium Propionate Or Sodium Butyrate Promotes Fatty Acid Oxidation In Hepg2 Cells Under Oxidative Stress, Kristina J. Cook, Ann Coulter, Michael Keenan, Frank Greenway, Jack N. Losso

Faculty Publications

The beneficial effects of sodium butyrate (NaB) and sodium propionate (NaP) on fatty acid oxidation (FAO) genes and production of proinflammatory cytokines related to nonalcoholic fatty liver disease (NAFLD) were evaluated using HepG2 human liver hepatocellular carcinoma cells exposed to palmitate/oleate or lipopolysaccharides (LPSs) as a model. The results showed that NaP or NaB was able to promote FAO, regulate lipolysis, and reduce reactive oxygen species production by significantly increasing the mRNA expression of peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α), peroxisome proliferator-activated receptor alpha (PPARα), adipose triglyceride lipase (ATGL), carnitine palmitoyltransferase 1 alpha (CPT1α), fibroblast growth factor 21 …

Adolescent Health And Maladaptive Coping: Assessing The Relationship Between Poor Physical Health And Underage Drinking, Shelby Gilbreath

Electronic Theses and Dissertations

Adolescents endure various stressors throughout their lives, making them one of the most vulnerable populations in the United States. Among those life stressors are physical health issues, including physical illness and disabilities. Physical health challenges may serve as a strain that fosters deviant behavior, such as underage drinking. However, prior research has failed to investigate this relationship. The current study uses publicly available data from the National Study of Adolescent to Adult Health (Add Health) to examine the impact of physical health challenges on underage drinking.

"Dug Way To Liberty": Newspapers, Prison, And Jim Crow In Georgia In The Early 1900s, Avery Elise Gross

Electronic Theses and Dissertations

On April 15, 1907, twelve Black and white convicts escaped from the Durham Mines prison camp located on Lookout Mountain, Georgia. Over the next month, newspapers throughout Georgia and in neighboring states reported the escape and discussed the recapture events. Within five days of the prison break, the local white community recaptured all nine Black convicts. None of the white convicts were caught. As this thesis investigates the lives, crimes, and recapture of all twelve prisoners, it connects the convict lease prison system with the newspaper media to understand the impact of white supremacy ideology and the repressive systems that …

Prevalence Of Meeting 24-Hour Movement Guidelines And Sociodemographic Correlates Among U.S. Adults, Samantha Cohen-Winans

Electronic Theses and Dissertations

Much evidence exists for the health benefits associated with individual movement behaviors, which include light-intensity physical activity (LPA), moderate-to-vigorous physical activity, sedentary behavior, and sleep. However, individual movement behaviors are codependent in nature and exist within a finite period of 24-hours, further underlying the importance of examining the integration of movement behaviors. Despite the absence of 24-hour movement guidelines in the U.S., the benefits of adhering to such guidelines outweigh the potential harms, such as with various levels of physical activity intensity. Moreover, many intervention studies focus on one individual movement behavior underscoring the need for studies to examine intervention …

The Relationship Between Alpha-Defensin 1 And Gut Microbiome Composition In A Population Of Bhutanese Refugee Adults With A High Prevalence Of Type 2 Diabetes, Daisha Alana Drake

Honors Theses and Capstones

The New Hampshire Bhutanese refugee population is disproportionately affected by obesity and metabolic disorders such as type 2 diabetes. The gut microbiome is important for overall human health, with high microbial richness and diversity being associated with reduced chronic inflammation and type 2 diabetes risk. Microbial richness and diversity have been shown to decrease in United States (U.S.) immigrant populations, but have not been measured in refugee populations. One of the anti-inflammatory functions of the gut microbiome is related to the production of short-chain fatty acids (SCFAs), which regulate pro-inflammatory cytokine production. Alpha-defensin 1 is an antimicrobial peptide that is …

Dog Weight, Age, And Sex Relationship With Shelter Length-Of-Availability At Pope Memorial Humane Society, Logan Lajoie

Sustainability Practices In Aquaculture: Using Algae Turf Scrubber Biomass To Raise Black Soldier Flies As An Alternative Feed In Blue Tilapia, Oreochromis Aureus, Culture, Michelle C. Lowery

College of Graduate Studies: Theses & Dissertations

Since the 1980s, non-algal aquaculture has grown to encompass 49% of all seafood production in response to a growing human population and increased seafood demand (FAO, 2022). Hurdles exist to aquaculture sustainability, including dependence on wild sourced fishmeal (FM) and the impacts wastewater discharge. It takes 4-5 tons of wild forage fish to produce one ton of dry FM (Miles and Chapman, 2006) and as aquaculture is primarily conducted in earthen ponds and public open water bodies (FAO, 2022), finfish culture can have a high impact on the surrounding environment by discharging excess nutrients. This study used algae turf scrubber …
