This study investigates the question of how the combination of different-age listeners and developmentally delayed individuals affects preadolescents' communication. While being videotaped in a lounge-like setting, two 11-year-old females separately interacted with three different same sex listeners: a younger nonhandicapped child (6 years old); a nonhandicapped peer (11 years old); and a retarded peer (also 11 years old). Measures were taken on the number, duration, and content of their initiated interactions. The results demonstrated that the speaker who addressed the less verbally adept retarded peer made more communicative adjustments than the speaker who talked with the more verbally advanced retarded peer, more than when she talked with the two nonhandicapped listeners. Also, both speakers seemed to talk to the younger child much like they spoke with the normal same-age peer. This finding suggests that the age of the listeners had less influence on the speaker's linguistic behavior than the developmental level of the listener.

This is the life history of Rend Percente from Little Farmer's Cay, Exuma, Bahamas. When the University of Arizona-College of the Bahamas research team visited Little Farmer's Cay during the Bahamas Biocomplexity Project, Rend asked the team to record his story. This document reflects this effort.

The population of older adults has grown rapidly in recent years and is expected to continue to grow into the middle of this century. The aging of the population means that nurses need to have specialized gerontological knowledge in order to properly care for older adults. In spite of the current need for specialists in this field, gerontological nursing is not a popular choice and nurses often lack adequate preparation to care for older adults. The complex reasons behind these issues are rooted in the history of the development of this specialty. This study takes a historical look at the development of gerontological nursing in British Columbia through the stories of seven nurse educators who were leaders and innovators in their field. The findings of the study tell a story of the nurses’ work to change unacceptable nursing practice, improve standards of care and professional status of gerontological nursing and advocate for older adults. In doing so, these nurses challenged cultural values about aging and care of older adults and worked toward giving gerontological nurses a voice in policy and decision-making. The findings from this study can be used to guide today’s gerontological nurses as they continue to develop this specialized field of nursing knowledge.

Objectives: This study aimed to assess the oral health status of the Toronto adult homeless population; to learn how they perceive their own oral health; and how they interact with the dental care system. Methods: This cross-sectional descriptive study collected data from 191 homeless adults who were randomly selected using a stratified cluster sample at 18 shelters. A questionnaire and clinical oral examination were conducted with participants. Results: The mean Decayed/Missing/Filled Teeth (DMFT) score of the subjects was 14.4 (SD=8.1). Only 32% of them had visited a dentist during the last year; 75% believed that they had untreated dental conditions; and 40% had their last dental visit for emergency care. The clinical oral examination observed that 88% needed fillings, 70% periodontal, 60% prosthodontic and 40% emergency treatment. Conclusion: Homeless adults in Toronto have poor oral health, significant oral health treatment needs and a lack of access to dental care.

Canadian government archives have primarily shaped scholars’ analysis of the File Hills farm colony on the Peepeekisis Reserve in south eastern Saskatchewan. While these colonial archives are valuable for research, they emphasise particular points in the government’s telling of the colony story. They focus on the construction, management, and intentions of the colony, but neglect the experiences and perspectives of Peepeekisis community members affected by the colony scheme. My thesis makes use of government archives, and is also based on Aboriginal oral histories about the colony and its long-term consequences. My central argument is that a more critical interpretation of archives and oral histories will enrich the historical and geographical record about the colony. I demonstrate how oral histories and archive documents can converge and diverge, but combining the two is particularly important to nuance the colony narrative. A critical viewing of texts and oral histories from the nineteenth and twentieth centuries also reveals that colonialism in the prairie west was highly spatalised and grounded in “betterment” sciences that sought to control and discipline Aboriginal peoples through the manipulation of space, heredity, and environments. Betterment sciences shaped Indian Affairs policy and the farm colony is a remarkable example of how betterment was applied on the ground. Finally, oral histories offer powerful insight into Aboriginal identities that survive in spite of colonial constructs and strategies. Oral histories of Peepeekisis community members are particularly important for highlighting peoples’ everyday geographies and lives only hinted at in colonial archive documents. Part of what makes this thesis original is that it is based on collaborative research. I sought Peepeekisis band permission to conduct this project, and Peepeekisis community members’ oral histories form an important part of this thesis and they have provided guidance on the documenting of their oral histories in this thesis. / Thesis (Ph.D, Geography) -- Queen's University, 2009-10-30 14:31:21.58

The goal of this study was to develop a model of the gastrointestinal tract (GIT) to be used for in vitro testing of oral insulin delivery devices. The method and intensity of mixing and effects of gastrointestinal fluids with and without enzymes were evaluated. Comparisons were made between an actively mixed simulator and a passively mixed simulator, where the actively mixed simulator is a magnetically stirred flask while the passively mixed simulator is a flexible container on a rocking stage. Slower mixing times and larger time constants for mixing were seen for the passively mixed simulator during a pH tracer experiment. Release studies were performed with several oral insulin delivery device models to evaluate the effects of different mixing techniques on insulin release. In all cases, the more intense mixing of the actively mixed simulator resulted in more insulin release. When using a nanoparticle model in intestinal fluid for example, 100% insulin release was observed in the actively mixed simulator while only 53% was released in the passively mixed simulator after 1 hour. Trypsin and pepsin were used to determine the ability of a drug delivery device to protect insulin from enzymatic degradation in which trypsin was added to simulated intestinal fluid and pepsin was added to simulated gastric fluid. Premature insulin release and insulin denaturation at body temperature occurred in the intestinal fluid so the protective effects against trypsin were unable to be effectively evaluated. An increase in insulin loss from 70% to 95% was detected in the presence of pepsin compared to gastric fluid without enzymes in the actively mixed simulator, indicating that acid hydrolysis of insulin as well as protease attack by pepsin will impact the behavior of an insulin delivery device. An improvement in insulin retention was observed in the passively mixed simulator. After 1 hour, insulin retained was increased from 4% in the actively mixed simulator to 10% in the passively mixed simulator, and after 2 hours, this increase was 2% to 7%. Premature insulin release from the delivery device, acid hydrolysis, temperature denaturation, and enzymatic degradation are factors limiting the effectiveness of oral insulin. / Thesis (Master, Chemical Engineering) -- Queen's University, 2011-08-19 19:29:52.804

<p>The aim of the study was to analyze oral health status(dental caries, periodontal conditions, fluorosis and malocclusion) of institutionalised children at Amani and Mkombozi street children homes in Moshi town, Tanzania. 100 street children participated. A cross sectional survey of street children between 12-18 years was carried out based on WHO guidelines. Self administered questionnaires were used to collect information from the caregivers.The findings indicate clear need to improve oral hygiene among these children.</p>
