Community Impacts Of Coastal Tourism In The Dominican Republic, Yolanda M. Leon

Open Access Dissertations

The present work presents the results of survey research conducted in 23 coastal communities of the Dominican Republic to evaluate the impacts of tourism and also the evaluation of a particular co-management system of a tourism-related activity (whale watching in Samaná Bay). Major findings include that tourism is having a positive impact on rural livelihoods as measured by increased household income, and higher levels of job satisfaction (and in the case of female-headed households, also improved material well-being). We also evidenced strong local support for the tourism industry caused by wide agreement on perceived tourism benefits; however, residents are also …

Ecomorphology Of The Temperate Scleractinian Astrangia Poculata: Coral-Macroalgal Interactions In Narragansett Bay, Sean Patrick Grace

Open Access Dissertations

Corals and macroalgae often co-occur on temperate reefs, where macroalgae provide a majority of the bio-complexity and small scleractinian corals occur in low abundance. Macroalgae typically outcompete adjacent organisms for resources such as space, light, and nutrients, and one mechanism for this competitive success is abrasion. This study explores factors that may influence the interactions between corals and macroalgae, in particular macroalgal abrasion, on a temperate reef in Narragansett Bay, Rhode Island. Chapter One examines how exposure, depth and orientation influence the abundance and morphology of the coral Astrangia poculata, as well as the percent cover of macroalgae and other …

Culture Of Summer Flounder Paralichthys Dentatus: Environmental And Endocrine Synchronization Of Growth And Settlement In Larvae And Identification Of Stressors In Juveniles, Steven Gavlik

Open Access Dissertations

This dissertation addresses the variability in settlement behavior, growth and development during metamorphosis of summer flounder. There were three objectives: (1) Expand basic knowledge of hormonal and environmental factors that regulate timing of metamorphosis, (2) develop hormonal and environmental techniques that promote synchronization of metamorphic growth and settling behavior in order to eventually reduce cannibalism in juveniles, and (3) identify stressful culture practices and evaluate their long-term effects on growth in juvenile flounder. The first and second objectives were accomplished through manipulations of cortisol and thyroxine and of rearing salinity. Endogenous whole-body cortisol concentrations increased through the late larval stages, …

Regulation Of Cra, A Regulatory Gene Of Glycolytic And Gluconeogenic Pathways In Salmonella Enterica Serovar Typhimurium, James H. Allen

Open Access Dissertations

The Cra protein is a global regulator of carbon and energy metabolism for glycolysis and gluconeogenesis. The live oral vaccine candidate, Salmonella typhimurium SR-11 Fad, is unable to utilize gluconeogenic substrates as sole carbon sources and is avirulent and protective in BALB/c mice. Furthemore, the era gene is interrupted in this strain of Salmonella. The cra gene was suspected to be regulated by another global regulator, acetyl phosphate. To further investigate the regulation of the cra gene and to determine if gluconeogenesis is linked to virulence, mutations in the gluconeogenic genes fbp (fructose-1,6-bisphosphatase), maeB (NADP-dependent malic enzyme), and sfcA …

Survival During And After Khmer Rouge, Sara S. Brown

Open Access Master's Theses

My personal life trauma experiences during the Khmer Rouge regime are described in this paper along with applications to Constructivist Self Development Theory (CSDT). This theory provides a basis for understanding the interrelatedness of biological and psychological self adaptation necessary to surviving and maintaining a consistent sense of self and the world. Five areas of self that were described in CSDT and which were applicable to my experiences of trauma are as follows:

1. Frame of reference: one's ability of understanding self and world, including spirituality. Although I was only seven years old at the time, somehow I understood the events …

Development And Validation Of The Proactive Health Lifestyle Measures, Norma Jean Perez

Open Access Dissertations

This research project targets the three leading causes of death in the U.S., cardiovascular disease, cancer, and stroke through the successful development and validation of six culturally sensitive Proactive Healthy Lifestyle measures (Stage of Change, Decisional Balance, Self-Efficacy, Skills, Relapse, and Processes of Change) targeting diet, exercise, and smoking. 574 college students were recruited and completed self-report surveys. Data from 418 non-Hispanics was used to develop (N = 209) and validate (N = 209) each of the measures. Data from 155 Hispanics was used to further successfully validate the measures, and explore differences in this group with the non-Hispanic group. …

A Meta-Analytic Examination Of Decisional Balance Across Stage Transitions: A Cross-Sectional Analysis And Cross-Sequential Cross-Validation, Kara L. Hall

Open Access Dissertations

Interventions to decrease unhealthy behaviors and to increase healthy behaviors are crucial for health promotion and disease prevention. Computerized tailored interventions provide a promising approach for creating positive health behavior change. The Transtheoretical Model (TTM) delineates a way to conceptualize behavior change, provides the foundation for developing assessments of an individual's readiness to change, and is utilized in tailoring interventions for actualizing behavior change. To produce optimally tailored interventions: (1) theory that guides interventions needs to be comprehensively tested; and (2) empirical data that drive the tailored interventions needs to be systematically generated. This program of research tests theoretical assumptions …

Metabolic Routing Of Macronutrients In Migratory Songbirds: Effects Of Diet Quality And Macronutrient Composition Revealed Using Stable Isotopes, David William Podlesak

Open Access Dissertations

Animals metabolically route specific macronutrients from their diet to build and maintain tissue and researchers generally assume that the isotopic composition of an animal's tissues resembles the isotopic composition of their diet. However, animals regularly change diets and they may route dietary macronutrients differently to specific tissues. Thus, I studied metabolic routing of dietary macronutrients into animal tissue because it is fundamentally important for understanding the nutritional ecology of wild vertebrates and because such knowledge is essential for accurate interpretation of stable isotope patterns in consumers and consumed. Songbirds that routinely switch their diets during migration provide a particularly interesting …

Parents' Descriptions Of Ideal Home Nursing Care For Their Technology Dependent Child, Themselves, And Their Families, Michele A. Mendes

Open Access Dissertations

Home care for technology dependent children is one of the fastest growing segments of the U.S. health care industry, but the nursing literature lacks clear directions to guide home care nurses in planning a family-centered practice. The purpose of this study is to address this gap in the literature by eliciting descriptions of ideal home nursing care for technology dependent children from the perspective of their parents, and to compile a comprehensive list of helpful and supportive nursing interventions. A qualitative, descriptive design was used to examine the following research questions: (1) How do parents of technology dependent children describe …

The Factors That Influence Middle-Level Teachers To Incorporate Community Service-Learning Into The Curriculum, Andrea J. Hainey-Turcotte

Open Access Dissertations

This study examined the factors that influence middle level educators to incorporate community service-learning into the curriculum. Eleven participants, each a teacher of middle level students, were interviewed to determine the extent to which they were influenced by intended outcomes for students, the community, and themselves. Findings suggest that participants were influenced to include community service-learning in the curriculum by anticipated benefits to students and community members. Participants hoped that by engaging in community service-learning activities, their students would become better scholars, leaders, citizens, and/or people. It would seem that participants were also driven to the implementation of community service-learning …

The Role Of Glycolytic Substrates In The Initiation And Maintenance Phases Of Colonization Of The Mouse Large Intestine By Escherichia Coli Mg1655 And Escherichia Coli Edl933, Regina L. Miranda

Open Access Dissertations

Escherichia coli is a gram-negative motile rod, and is one of the most common bacterial strains isolated from the human intestinal tract (1,2). E. coli K-12, strain MG1655, is a non-pathogenic laboratory strain of E. coli whose genome has been fully sequenced (1). E. coli O157:H7, strain EDL933, a shigatoxin-producing E. coli (STEC), is a human pathogen, whose genome has also been fully sequenced (34). E. coli EDL933 was first isolated in August of 1982 from patients in the United States suffering from an outbreak of bloody diarrhea, which was traced to contaminated hamburgers (8,9,10,11). E. coli O157:H7 infections are …

Effects Of Food Consumption And Temperature On Growth Rate And Biochemical-Based Indicators Of Growth In Early Juvenile Atlantic Cod Gadus Morhua And Haddock Melanogrammus Aeglefinus, Myron Arms Peck, Lawrence J. Buckley, Elaine M. Caldarone, David A. Bengtson

Fisheries, Animal and Veterinary Sciences Faculty Publications

The relationship between the somatic growth rate (G) and feeding level (unfed, intermediate, and maximum rations) of age-0 juvenile cod Gadus morhua and haddock Melanogrammus aeglefinus was quantified at different temperatures. Laboratory trials were conducted using 2 sizeclasses of cod (3.6 to 5.6 cm standard length [SL], and 8.1 to 12.4 cm SL) at 5, 8, 12, and 15°C, and 1 size-class of haddock (6.0 to 9.6 cm SL) at 8 and 12°C. The shape of the growth-feeding relationship was well described by a 3-parameter asymptotic function for cod and by a linear function for haddock (R² range …

Expression Of Spot In Borrelia Burgdorferi During Serum Starvation, Marc B. Concepcion, David R. Nelson

Cell and Molecular Biology Faculty Publications

Borrelia burgdorferi, the causative agent of Lyme disease, is transmitted by the tick Ixodes scapularis. A 2.9-kb fragment containing a putative spoT gene was isolated from B. burgdorferi genomic DNA by PCR amplification and cloned into a pBAD24 vector. The cloned gene complemented Escherichia coli mutant strain CF1693, which contains deletions of both the relA and spoT genes. The spoT gene in E. coli encodes a bifunctional enzyme capable of synthesizing and degrading (p)ppGpp, which mediates the stringent response during carbon source starvation. B. burgdorferi has been reported to have a stress response to serum starvation. Thin-layer chromatography …

Biological Control Of The Lily Leaf Beetle, Lilioceris Lilii In North America, Marion Secrest Gold

Open Access Dissertations

The lily leaf beetle, Lilioceris lilii (Scopoli), first officially reported in the U.S. in 1992, has become a serious pest of native and cultivated lilies throughout its North American distribution. With no effective North American natural enemies, this exotic insect poses a potential economic threat to horticulturists and an environmental threat to native lilies. This study presents the results of an ongoing classical biological control program initiated against L. lilii in North America. Based on its Eurasian geographic distribution, L. lilii seems capable of spreading throughout much of North America. In Europe, the lily leaf beetle is well known but …

Longitudinal Study Of The Acquisition Of Locomotion, Motor Activity, And Infant Development, Janette Baird

Open Access Dissertations

This study explored the relationship between the age of development of 5 locomotor behaviors, the level of infant activity for the locomotor behaviors, and the performance of the sample of infants on standardized indices of infant development (Fagan Test of Infant Intelligence, FTII; Bayley Scales of Infant Development, BSID-II). A total of 157 infants were assessed at 6, 9, and 12 months for their activity levels on the 5 locomotor behaviors of interest, and the age at which each locomotor behavior occurred was obtained through records maintained by each infants' caregiver. The results of the regression path analysis indicates that …
