Cherts from the Middle Devonian Onondaga Formation of the Niagara Peninsula in Southern Ontario and Western New York State can now be distinguished from those of the Early Devonian Bois Blanc Formation of the same area based on differences in petrology, acritarchs, spores, and "Preservation Ratio" values. The finely crystalline, carbonate sediments of the Bois Blanc Formation were deposited under shallow, low energy conditions characterised by the acritarchs Leiofusa bacillum and L. minuta and a high relative abundance of the spore, Apiculiretusispora minor. The medio crystalline and bioclastic carbonate sediments of the Onondaga Formation were deposited under shallow, high energy conditions except for the finely crystalline lagoonal sediments of the Clarence Member which is characterised by the acritarchs Leiofusa navicula, L. sp. B, and L. tomaculata . The author has subdivided and correlated the Clarence Member of the Onondaga Formation using the "Preservation Ratio" values derived from the palynomorphs contained in the cherts. Clarence Member cherts were used by the Archaic people of the Niagara Peninsula for chipped-stone tools. The source area for the chert is considered to be the cobble beach deposits along the north shore of Lake Erie from Port Maitland to Nanticoke

Molecular mechanics calculations were done on tetrahedral phosphine oxide zinc complexes in simulated water, benzene and hexane phases using the DREIDING II force field in the BIOGRAF molecular modeling program. The SUN workstation computer (SUN_ 4c, with SPARK station 1 processor) was used for the calculations. Experimental structural information used in the parameterization was obtained from the September 1989 version of the Cambridge Structural Database. 2 Steric and solvation energies were calculated for complexes of the type ZnCl2 (RlO)2' The calculations were done with and without inclusion of electrostatic interactions. More reliable simulation results were obtained without inclusion of charges. In the simulated gas phase, the steric energies increase regularly with number of carbons in the alkyl group, whereas they go through a maximum when solvent shells are included in the calculation. Simulated distribution ratios vary with chain length and type of chain branching and the complexes are found to be more favourable for extraction by benzene than by hexane, in accord with experimental data. Also, in line with what would be expected for a favorable extraction, calculations without electrostatics predict that the complexes are better solvated by the organic solvents than by water.

Some Ecological Factors Affecting the Input and Population Levels of Total and Faecal Coliforms and Salmonella in Twelve Mile Creek, Lake Ontario and Sewage Waters Near St. Catharines, Ontario. Supervisor: Dr. M. Helder. The present study was undertaken to investigate the role of some ecological factors on sewage-Dorne bacteria in waters near St. Catharines, Ontario. Total and faecal coliform levels and the presence of Salmonella were monitored for a period of a year along with determination of temperature, pH, dissolved oxygen, total dissolved solids, nitrate N, total phosphate P and ammonium N. Bacteriological tests for coliform analysis were done according to APHA Standard Methods by the membrane filtration technique. The grab sampling technique was employed for all sampling. Four sample sites were chosen in the Port Dalhousie beach area to determine what bacteriological or physical relationship the sites had to each other. The sample sites chosen were the sewage inflow to and the effluent from the St. Catharines (Port Dalhousie) Pollution Control Plant, Twelve Mile Creek below the sewage outfall and Lake Ontario at the Lakeside Park beach. The sewage outfall was located in Twelve Mile Creek, approximately 80 meters from the creek junction with the beach and piers on Lake Ontario. Twelve Mile Creek normally carried a large volume of water from the WeIland Canal which was diverted through the DeCew Generating Station located on the Niagara Escarpment. An additional sample site, which was thought to be free of industrial wastes, was chosen at Twenty Mile Creek, also in the Niagara Region of Ontarioo 3 There were marked variations in bacterial numbers at each site and between each site, but trends to lower_numbers were noted from the sewage inflow to Lake Ontario. Better correlations were noted between total and faecal coliform population levels and total phosphate P and ammonium N in Twenty Mile Creek. Other correlations were observed for other sample stations, however, these results also appeared to be random in nature. Salmonella isolations occurred more frequently during the winter and spring months when water temperatures were minimal at all sample stations except the sewage inflow. The frequency of Salmonella isolations appeared to be related to increased levels of total and faecal coli forms in the sewage effluent. However, no clear relationships were established in the other sample stations. Due to the presence of Salmonella and high levels of total and faecal coliform indicator organisms, the sanitary quality of Lake Ontario and Twelve Mile Creek at the sample sites seemed to be impaired over the major portion of the study period.

Previous research has found that victims of crime tend to exhibit asynchronous movement (e.g. Grayson & Stein, 1981), and the fact that victims display different body language suggests that they may be sending inadvertent signals to their own vulnerability (e.g. Murzynski & Degelman, 1996). Body language has also be en linked with s e l f identification as a victim (Wheeler et aI., 2009), and self-identification has be en found to act as a proxy for more severe victimization (Baumer, 2002) and greater fear of crime (Greenberg & Beach, 2004). The first prediction in the present study, then, was that self-perceived vulnerability would be correlated with body language, while number of previous victimizations mayor may not show the same relationship. Findings from the present study indicate that self-perceived vulnerability exhibits a positive correlation with the body language cues that approaches significance r (10) = .45,p =.07, one-tailed. Different types of victimization, however, were not significantly correlated with these cues. A second goal of the study was to examine the relationship between psychopathic traits and accuracy in judgments of vulnerability. Seventy male participants rated the vulnerability of 12 female targets filmed walking down a hallway who had provided selfratings of vulnerability. Individuals scoring higher on Factor 2 and total psychopathy were significantly less discrepant from target self-rat~ngs of vulnerability, r (64) = - .39,p < .001; r (64) = - .29,p >.01, respectively. The final purpose of this study was to determine which body language cues were mos t salient to raters when making judgments of vulnerability. Participants rated the apparent vulnerability of a target in 7 video clips portraying each body language cue in isolation and a natural walk. Results of repeated measures analyses indicate that the videos rated as most vulnerable to victimization were those displaying low energy and l a ck of synchrony, followed by wide stride, short stride, and stiffknees, while the video displaying ne ck stiffness did not receive significantly different ratings from the mode l ' s natural walk. Replication with a larger sample size is necessary to increase confidence in findings and implications.

As the complexity of evolutionary design problems grow, so too must the quality of solutions scale to that complexity. In this research, we develop a genetic programming system with individuals encoded as tree-based generative representations to address scalability. This system is capable of multi-objective evaluation using a ranked sum scoring strategy. We examine Hornby's features and measures of modularity, reuse and hierarchy in evolutionary design problems. Experiments are carried out, using the system to generate three-dimensional forms, and analyses of feature characteristics such as modularity, reuse and hierarchy were performed. This work expands on that of Hornby's, by examining a new and more difficult problem domain. The results from these experiments show that individuals encoded with those three features performed best overall. It is also seen, that the measures of complexity conform to the results of Hornby. Moving forward with only this best performing encoding, the system was applied to the generation of three-dimensional external building architecture. One objective considered was passive solar performance, in which the system was challenged with generating forms that optimize exposure to the Sun. The results from these and other experiments satisfied the requirements. The system was shown to scale well to the architectural problems studied.

This thesis describes syntheses and catalytic reactivity of several half-sandwich complexes of ruthenium. The neutral ruthenium trihydride complex, Cp(PPri3)RuH3(1), can efficiently catalyse the H/D exchange reaction between various organic substrates and deuterium sources, such as benzene-d6. Moreover, the H/D exchange reactions of polar substrates were also observed in D2O, which is the most attractive deuterium source due to its low cost and low toxicity. Importantly, the H/D exchange under catalytic conditions was achieved not only in aromatic compounds but also in substituted liphatic compounds. Interestingly, in the case of alkanes and alkyl chains, highly selective deuterium incorporation in the terminal methyl positions was observed. It was discovered that the methylene units are engaged in exchange only if the molecule contains a donating functional group, such as O-and N-donors, C=C double bonds, arenes and CH3. The cationic half-sandwich ruthenium complex [Cp(PPri3)Ru(CH3CN)2]+(2) catalyses the chemoselective mono-addition of HSiMe2Ph to pyridine derivatives to selectively give the 1,4-regiospecific, N-silylated products. An ionic hydrosilylation mechanismis suggested based on the experiments. To support this mechanistic proposal, kinetic studies under catalytic conditions were performed. Also, the 1,4-regioselective mono-hydrosilylation of nitrogen containing compounds such as phenanthroline, quinoline and acridine can be achieved with the related Cp*complex [Cp*(phen)Ru(CH3CN)]+(3) (phen = 1,10-phenanthroline) and HSiMe2Ph under mild conditions. The cationic ruthenium complex 2 can also be used as an efficient catalyst for transfer hydrogenation of various organic substrates including carbonyls, imines, nitriles and esters. Secondary alcohols, amines, N-isopropylidene amines and ether compounds can be obtained in moderate to high yields. In addition, other ruthenium complexes, 1,3 and [Cp*(PPri3)Ru(CH3CN)2]+(4), can catalyse transfer hydrogenation of carbonyls although the reactions were sluggish compared to the ones of 2. The possible intermediate, Cp(PPri3)Ru(CH3CN)(H), was characterized by NMR at low temperature and the kinetic studies for the transfer hydrogenation of acetophenone were performed. Recently, chemoselective reduction of acid chlorides to aldehydes catalysed by the complex 2 was reported. To extend the catalytic reactivity of 2, reduction of iminoyl chlorides, which can be readily obtained from secondary amides, to the corresponding imines and aldehydes was investigated. Various substituted iminoyl chlorides were converted into the imines and aldehydes under mild conditions and several products were isolated with moderate yields.

Cette recherche vise à documenter l’expérience scolaire des élèves québécois d’origine chinoise à l’école secondaire de langue française et à examiner les dynamiques qui influencent la réussite scolaire de ces élèves. Elle s’intéresse plus précisément aux impacts des facteurs relatifs à l’école, à la famille immigrante, et à ceux de la communauté ethnique sur l’intégration de ces jeunes dans un contexte francophone. Les données ont été principalement recueillies à travers des entretiens semi-structurés approfondis auprès d’élèves d’origine chinoise et de différents acteurs du paradigme éducatif (parents, acteurs scolaires et intervenants communautaires). D’autres instruments, tels que l’analyse du contenu de documents et de médias, ont également été utilisés afin de fournir des informations contextuelles et d’enrichir les données d’entrevues. Les données ont été analysées selon un cadre théorique ouvert et inclusif où la réussite scolaire des élèves issus de l’immigration est mesurée en mettant l’accent sur l’influence de la maîtrise de la langue d’enseignement, du capital culturel et social de la famille et de la communauté immigrante, ainsi que des facteurs systémiques au niveau de l’école. Les résultats de cette étude dans trois écoles cibles montrent qu’en général les élèves d’origine chinoise connaissent une expérience positive, surtout en ce qui concerne leur performance scolaire en mathématiques et sciences. Cependant, les nouveaux arrivants ont tendance à éprouver des difficultés dans l’apprentissage du français et pour leur intégration sociale. En effet, le processus d’intégration socioscolaire des jeunes chinois est sous l’influence des différents milieux qu’ils fréquentent. À propos de l’influence des dynamiques scolaires, les résultats de la recherche indiquent qu’une relation maître-élève positive joue un rôle important dans la réussite éducative de ces élèves. Toutefois, l’insuffisance du soutien à l’apprentissage défavorise l’intégration linguistique et sociale des élèves nouvellement arrivés. Les données de cette étude soulignent notamment le rôle de la famille immigrante et de la communauté ethnique dans l’expérience scolaire de ces jeunes. D’une part, sous l’impact des dynamiques familiales, notamment ce qui à trait au projet migratoire, à la culture chinoise et à l’expérience pré- et post-migratoire, les parents immigrants chinois s’impliquent activement dans les études de leurs enfants, malgré des barrières linguistiques et culturelles. D’autre part, afin de surmonter les effets négatifs des faibles liens entretenus avec l’école de langue française, les parents chinois ont largement recours aux ressources au sein de la communauté ethnique, tels que les médias de langue chinoise, les organismes ethnospécifiques de services aux immigrants, l’école du samedi et les institutions religieuses ethniques. Ces institutions sociales ethniques contribuent à soutenir les valeurs culturelles, échanger des informations, établir des modèles pour les jeunes et à fournir des services appropriés en matière culturelle et linguistique.

Ce mémoire de maîtrise porte sur les effets politiques des discours médiatiques sur la gouvernance et la régulation des demandeurs d’asile au Canada. À travers une analyse critique des discours de la presse écrite canadienne au sujet de l’arrivée en août 2010 de 492 requérants du statut de réfugié à bord du bateau MV Sun Sea en Colombie-Britannique, l’auteure identifie les principales interprétations de cet évènement ainsi que leurs relations avec la mise en place subséquente de mesures visant à restreindre les possibilités d’accès non autorisés au Canada, notamment par la création d’une nouvelle catégorisation discriminatoire des demandeurs d’asile. L’analyse révèle l’articulation de ces discours autour de deux thématiques distinctes, mais interreliées. Tandis que les discours sécuritaires associent l’arrivée non autorisée des demandeurs d’asile à une menace à la sécurité de la nation, les discours humanitaires interprètent cet évènement comme une demande d’aide de la part d’un groupe de personnes menacées par leur propre pays. Ce mémoire propose une analyse multidimensionnelle de ces deux cadrages et de leurs effets politiques qui considère leurs dimensions discursives, contextuelles et affectives. L’analyse démontre comment ces deux discours en apparence conflictuels partagent en fait un même sous-texte racial qui fait de ce type de spectacle médiatique un dispositif clé de « gouvernementalité racialisée de l’immigration » (Bilge, 2012, 2013).

This dissertation examines gendered fictional dialogue in popular works by D.H. Lawrence, Ernest Hemingway and E.M. Forster, including Howards End (1910), The Sun Also Rises (1926) and Lady Chatterley’s Lover (1928). I apply Judith Halberstam’s notion of female masculinity to direct speech, to explore how speech traits inform modernist literary aesthetics. My introduction frames this discussion in sociolinguistics, Judith Butler’s theory of performativity, M.M. Bakhtin’s discourse theory, and gender studies. It provides an opportunity to establish experimental dialogue techniques, and the manipulation of gendered talk, in transgressive texts including James Joyce’s Ulysses (1922), Virginia Woolf’s Orlando (1928) and Radcyffe Hall’s The Well of Loneliness (1928). The first chapter discusses taboos and dialect in D.H. Lawrence’s fictional dialogue. The second chapter establishes gender subversion as a crucial element in Ernest Hemingway’s dialogue style. The third chapter contrasts Forster’s latently gendered speech with his techniques of dialect emphasis and dialect suppression. Finally, my conclusion discusses gender identity in the poetry of Dorothy Parker and Baroness Elsa von Freytag Loringhoven, and the temporality of gender in “Time Passes” from Virginia Woolf’s To the Lighthouse (1927). New Woman characters like Lady Brett Ashley typified a crucial moment in women’s liberation. They not only subverted stereotypes of womanhood through their dress or sexual freedom, they also adopted/adapted masculine idiom to shock, to rebel against and challenge male dominance. Different speech acts incited fashionable slang, became a political protest symbol or inspired psychoanalytic theory. The intriguing functions of women’s masculine speech in early twentieth century fiction establishes the need to examine additional connections between gender and talk in literary studies.

In the present thesis the petrographic, geochemical and digenetic variability of the sediments in the islands of Kavaratti and Minicoy has been investigated .The beach profile studies show that in the Kavaratti lagoon beach, the slope is steeper in the southern and south central part than in the northern end’s marginal deposition is taking place in the northern end of the Kavaratti island, whereas a marginal erosion is observed at the southern end. In Minicoy the slope of the lagoon beach is gentle in the south and is slightly steeper at the northern part of the beach. The southern and northern beach sections show a marginal deposition. Based on the mineralogical and geochemical studies it is concluded that the main digenetic changes observed is the transformation of aragonite to LMC.The transformation takes place mainly in the vadose zone and is caused by the abundance of fresh water infiltration.
