Ultimately, it will find that regardless of academic or social rank or citizenship, all participants in the debate relied on one common idea to support their arguments and criticize their opponents: that of the ‘colonial mentality’, or the notion that Canadians unquestionably accepted their country as subservient to the United States. Ultimately, this paradoxical usage of postcolonial themes represented an underlying ambivalence in regards to what was being debated in the first place. Thus this essay strives to address how a specific dispute within academia could, in Mathews and Steele’s words, evolve into a “struggle for the very existence of Canada as a self-respecting and independent community” [1a]. Moreover, it contributes to a deeper understanding of Canadian-American relations and the recent debate on Canadian universities’ hiring practices, which continues to be an issue nearly forty years later. In doing so it presents a fascinating case study of national identity within postcolonial frameworks.","PeriodicalId":413751,"journal":{"name":"Studies by Undergraduate Researchers at Guelph","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133420512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used a captive deaf Atlantic bottlenose dolphin (Tursiops truncatus) to test the hypothesis that hearing loss would decrease a dolphin’s ability to acquire food by preventing echolocation (using echoes to locate fish). Reaction time (time to acquire dropped fish) and success rate (percentage of successfully acquired fish) were measured for the deaf dolphin and for two dolphins with no known hearing disabilities at Dolphins Plus in Florida in May 2009. The deaf dolphin had a significantly slower mean reaction time and a significantly lower mean success rate than those of the two other dolphins. A hydrophone suggested that the deaf dolphin could not echolocate, and thus relied mainly on vision. The results illustrate that hearing loss can negatively affect a dolphin’s ability to acquire food. Therefore, sources and effects of dolphin hearing loss require further investigation in order to provide targets for anthropogenic noise levels.","PeriodicalId":413751,"journal":{"name":"Studies by Undergraduate Researchers at Guelph","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123961874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes molecular dynamics (MD) approaches to study the properties of biological membranes and proteins using the freely available GROMACS package on the C-terminal α-helical peptide of myelin basic protein (MBP). We simulated a mixed membrane – consisting of 2-dimyristoyl-sn-glycero-3-phosphocholine/1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine (DMPC/DMPE), and a pure DMPC membrane, composed of 188 and 248 lipids, respectively – for 200 ns at 309K. The DMPC membrane was approximately three times more fluid compared to the DMPC/DMPE system, with the diffusion coefficients (D) being 0.0207x10-5 cm2/s and 0.0068x10-5 cm2/s, respectively. In addition, we simulated the 14-residue peptide representing the C-terminal α-helical region of murine MBP, with sequence NH2-A141YDAQGTLSKIFKL154-COOH, in both membrane systems for 200 ns. The negatively-charged N-terminal end of the peptide penetrated further into the DMPC bilayer than into the mixed DMPC/DMPE bilayer. Reduced peptide accessibility to a formal positive charge of the DMPC amine ‘N’ atom surrounded by methyl and methylene groups may be the cause [1]. The peptide lost its α-helical structure in DMPC/DMPE but not in the DMPC bilayer. These findings show that membrane composition affects MBP’s interaction with it, a phenomenon that provides insights into myelin structure – and that may eventually be relevant to understanding the pathogenesis of multiple sclerosis (MS).","PeriodicalId":413751,"journal":{"name":"Studies by Undergraduate Researchers at Guelph","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116821617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smell and taste deficits associated with Late-Onset Alzheimer’s Disease (LOAD) may accentuate the decline in nutritional status of elderly individuals and indirectly enhance progression of cognitive problems in LOAD. The objective of this study was to explore and characterize smell and taste recognition abilities in early stages of LOAD, beyond that of normal healthy aging. A total of 29 healthy-younger subjects aged 18-40 (HY), 13 healthy-elderly (HA) and six elderly adults diagnosed with LOAD (AD) aged 60-85, were recruited from the Guelph community. The Sniffin’ Sticks Screening Test (SSST) and Taste Strips were used to test olfactory and gustatory functions, respectively. Participants also completed the mini-mental state examination (MMSE), clock test and word recall tests to assess cognitive/memory skills. Compared to HA individuals, people with AD had significant odour recognition impairment. Correlation analysis also revealed an age-associated decline in overall taste ability. When specific tastes were examined, impairments in sour and bitter identification were observed with increasing age. However, no significant differences in specific taste abilities were found between HA and AD individuals. In predicting health status (ie. presence or absence of LOAD), an assessment of all variables in this study was conducted using Generalized Linear Model (GLM). Results showed that sweet recognition and clock test scores were the best predictive variables of health status. However, this is a preliminary model that needs refinement through further research using more individuals.","PeriodicalId":413751,"journal":{"name":"Studies by Undergraduate Researchers at Guelph","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127944662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
