This thesis is an analysis and evaluation of a case study in deinstitutionalisation of people with intellectual disabilities. The process has been viewed as an example of organisational change and the focus is on the relationship between formal and informal caregivers and the notion of care. Three key groups were included in the study, families of residents, the residents and staff. A qualitative approach was taken. The theoretical perspective that was developed attempted to account for links between social movements, organisations and individual experience in the arena of intellectual disability. This was based on the approach of New Institutionalism in organisational theory. The focus was primarily on the process--of change, and in caregiving. Three models of intellectual disability, which have informed policy and the recent changes to a preference for community care, have been identified and the links between these and the elements of organisations developed for providing care explored. The experience of families and residents within the hospital setting and then the community care setting has been examined in relation to the nature of the organisation. Outcomes for the three groups have been examined in terms of their needs and the extent to which these needs were met by the arrangements over a given time. It is concluded that community care has the potential to better meet the needs of those involved, than has hospital based care. A number of factors in the process of change and in the delivery of care have been identified as impacting on outcomes for those involved. Consideration is given to the practical implications of these findings. / Subscription resource available via Digital Dissertations only.

Master of Public Health / Public Health Interdepartmental Program / Kate KuKanich / The College of Veterinary Medicine (CVM) environment is a place where veterinarians, veterinary staff, and veterinary students may have increased risk of exposure to zoonotic pathogens. This exposure may occur in classrooms or laboratories where pre-clinical veterinary students and non-clinical staff frequent. Exposure may also occur in the veterinary teaching hospital (VTH) and may impact veterinary patients, clinicians, interns, residents, veterinary technicians, veterinary students, animal caretakers, and others. This thesis is divided into 3 chapters. The first chapter describes a current review of the literature involving risk of zoonotic pathogen exposure at VTHs including descriptions of the most commonly documented zoonotic pathogens and their transmission, environmental sources of zoonotic pathogens at VTHs, and ways to prevent zoonotic pathogen exposure at individual and institutional levels. The second chapter describes an original research study of hand hygiene behavior among pre-clinical veterinary students at a CVM. The purpose of this study was to determine if a campaign could improve hand hygiene among veterinary students at extracurricular meetings serving meals. Campaign interventions included a 3.5 minute educational video and a novel motivational poster. The video was presented to all 1st, 2nd, and 3rd year veterinary students. Posters encouraging hand sanitization were displayed on doors and tables alongside sanitizers at each meeting. Observational hand hygiene data were collected immediately after introduction of interventions and again 3 months later. Environmental sampling for presence of bacteria in and around meeting locations was also performed. Observed hand hygiene was lowest during baseline (11.0% +/- 1.7), improved significantly post-intervention (48.8% +/- 3.2), and remained improved at 3-month follow-up (33.5% +/-4.0). Females had higher probability of hand- sanitizing (35.9% ± 2.2) than males (21.4% ± 2.4) (p<0.01). Clostridium perfringens was isolated from 2/42 samples, and Salmonella spp. were isolated from 4/42 samples. This study documented that a short-term public health campaign targeting veterinary students successfully improved hand hygiene before meals. The final chapter discusses future areas of research in the realm of risk of zoonotic pathogen exposure and risk mitigation at CVMs.

Doctor of Philosophy / Food Science Program / Daniel Y.C. Fung / Curtis L. Kastner / This dissertation was designed to evaluate antimicrobial, quality, and shelf life effects of controlled phase carbon dioxide (CPCO2) on beef trimmings destined for ground beef. Critical parameters included pressure, temperature, exposure times, modified atmosphere conditions, and days of simulated retail display. 1500 psi CPCO2 for 15 min achieved 0.83, 0.96, 1.00, and 1.06 log reductions for Total Plate Count (TPC), Generic E. coli (GEC), E. coli O157:H7 (O157), and Salmonella spp. (SS), respectively. Bacterial reductions in ground beef and beef trimmings were similar (P≥0.05). CIE L*, a*, and b* values in raw patties showed no differences (P≥0.05) immediately after CPCO2 application on beef trimmings. Nevertheless, significant (P<0.05) interactions were found in pressure by packaging for L*, in pressure by packaging by days of simulated retail display for a*, and in packaging by days of simulated retail display for b* scores. Nevertheless, after 5 days of simulated retail display, L*, a*, and reflectance (630/580nm) ratios were similar for all treatments (P≥0.05), and b* scores were most acceptable with 1500 CPCO2 (P≥0.05), regardless of the packaging conditions. After 5 days of display, cooked patties showed similar (P≥0.05) values for crude protein (%CP) and crude fat (%CF), the extent of lipid oxidation (TBARS), was higher (P0.05) in aerobic trays than flushed packages with 100% CO2. Ground beef patties manufactured from beef trimmings treated with CPCO2scored higher values for tenderness (P0.05) than other treatments. In addition, no differences (P0.05) for juiciness, beef flavor intensity, or off flavor intensity were found between non-treated and the 1500 psi CPCO2 treated patties. Microbial control of spoilage organisms and foodborne pathogens in ground beef patties with CPCO2 application in beef trimmings was effective (0.6 to 1.2 logs). Lethality levels are comparable to other intervention strategies. Discoloration of beef trimmings after CPCO2 application may not be a concern for grinding purposes. Further packaging with 100% CO2 is viable for controlling spoilage and pathogenic microorganisms after packaging and during refrigerated storage, although discoloration of raw ground beef patties packaged with 100% CO2 may be a concern for product marketing.

Doctor of Philosophy / Department of Human Nutrition / David A. Dzewaltowski / The environment can be broadly defined as all things external to an individual. One of the most important environments for children is the home in which they live, particularly with regard to the role that parents play to provide opportunities for healthful development, including adequate physical activity and healthful eating habits. Parents are the gatekeepers of children's healthful opportunities, and are influential in numerous aspects related to obesity. The present paper consists of four chapters related to impacting the home environment for prevention of obesity in children. Although obesity is a complex issue, its cause is energy imbalance, wherein less energy is expended than is consumed. Consideration of both sides of the equation is essential for obesity prevention. In this dissertation, chapter 1 serves as a literature review for the home food environment. A conceptual model is presented as an attempt to place relevant literature in the greater context of environmental variables related to childhood obesity. Frequent family meals have been shown to be protective for child and adolescent obesity, and to promote fruit and vegetable consumption. However, time pressures and lack of cooking skills are potential barriers to this healthful practice. Decreases in television viewing and sugar-sweetened beverage consumption are other home environmental aspects showing promise in the obesity prevention literature. Chapters two and three address the influence of parents on children's obesity-preventive behaviors and relative weight status. These chapters help to inform the planning of interventions to prevent obesity in children. Parent-child shared physical activity may hold promise as a strategy to decrease the likelihood of children becoming obese, and bonding may be an important consideration in programs aimed at obesity treatment or prevention. Chapter four describes the evaluation of an intervention developed to impact the home environment of young girl scouts. This intervention was implemented by troop leaders altering troop-meeting environments toward more healthful opportunities for physical activity and nutrition, and through the delivery of a scouts-tailored curriculum. Results of the intervention showed marked changes to troop meeting environments, but apparently little impact on parents or the home environment.

Doctor of Philosophy / Department of Entomology / Ludek Zurek / House fly (Musca domestica L.) larvae develop in decaying organic substrates such as animal manure and adult flies likely play an important role in the ecology of fecal bacteria, including potentially virulent strains. House fly larval development strictly depends on an active bacterial community in the habitat. Although the principle of this symbiosis is not well understood, this association plays a fundamental role in transmission of microbes by this insect. In this study, enterococci were chosen as a model organism to assess the role of house flies in dissemination of multi-drug resistant bacteria in the agricultural environment. House flies (FF) and cattle manure (FM) from a cattle feedlot (frequent use of antibiotics) and house flies (BF) and manure of the American bison (BM) from the Konza Prairie Nature Preserve (no antibiotic use) were collected and analyzed. Results showed a significantly higher prevalence of enterococci resistant to tetracycline and erythromycin in FM and FF compared to that of BF and BM. Enterococcal diversity did not indicate the house fly development in manure in the corresponding habitats but the antibiotic resistance data showed very similar profiles among isolates from flies and corresponding locations. Resistance genes (tetM, tetS, tetO, ermB) and the conjugative transposon Tn916 were the most commonly detected determinants from resistant isolates from both environments. The house fly digestive tract was evaluated for the potential for horizontal transfer of antibiotic resistance genes among Enterococcus faecalis. Horizontal transfer of the pCF10 plasmid with the tetracycline resistance gene (tetM) occurred in the fly digestive tract with a transfer rate up to 101 T/D. In addition, eight enterococcal species were selected to evaluate their role and survival during house fly development. Overall, the survival rate (egg to adult) was significantly higher with E. hirae, E. durans and E. avium compared to other strains. These results indicate: a) house flies play an important role in the ecology of antibiotic resistant enterococci; b) the house fly digestive tract provides conditions for horizontal gene transfer among enterococci, and c) enterococci support the house fly development and can colonize the gut of newly emerging adult flies.

Master of Science / Department of Family Studies and Human Services / Anthony Jurich / This study explored the parents’ perspective of having a child with Autism living in the home. Specifically, the researcher was looking to explore the attachment style between the parent and child, as well as the process of the parents’ changing their expectations of their child, from the expectation of raising a normal child to raising a child with Autism. In order to understand the experience of both families interviewed, the researcher, through semi-structured, qualitative interviews, interviewed each parent separately. A multiple case study approach was used in order to allow for comparison within each family. Methods for analyzing the data included coding the data, so that the data could be analyzed from the individual interviews and also analyzed based on family response. For the parents interviewed in the study, four themes emerged that were similar for all parents. These themes included the diagnosis process, the differences in attachment before and after their child was diagnosed, the changing expectations of themselves, each other and their diagnosed child, and the parents’ views on getting professional help, such as therapy. Both families shared the experience of confusion during the diagnostic process, especially confusion surrounding the cause and prognosis of Autism. All parents in the study illustrated the attachment injury after their child’s diagnosis, in addition to when the child began showing the classic signs of Autism. The study also found that each parent’s expectations changed from higher ones of themselves, spouse and diagnosed child to more moderate and low expectations of their spouse and diagnosed child. Last, all parents interviewed expressed that seeking therapy would have helped them deal with the diagnostic process and better cope with having a child with Autism. It is believed by the researcher that these themes have emerged because of the families’ shared experience of raising an Autistic child.
