Walter D’Arcy Ryan was born in 1870 in Kentville, Nova Scotia. He became the chief of the department of illumination at the General Electric Company of Schenectady, New York. He was a founder in the field of electrical illumination. He built the electric steam scintillator which had numerous nozzles and valves. The operator would release steam through the valves. The nozzles all had names which included: Niagara, fan, snake, plume, column, pinwheel and sunburst. The steam scintillator was combined with projectors, prismatic reflectors, flashers and filters to produce the desired effects. In 1920 a group of businessmen from Niagara Falls, New York formed a group who called themselves the “generators’. They lobbied the American and Canadian governments to improve the illumination of the Falls. They were able to raise $58, 000 for the purchase and installation of 24 arc lights to illuminate the Falls. On February 24th, 1925 the Niagara Falls Illumination Board was formed. Initially, the board had a budget of $28,000 for management, operation and maintenance of the lights. The power was supplied free by the Ontario Power Company. They had 24 lights installed in a row on the Ontario Power Company surge tank which was next to the Refectory in Victoria Park on the Canadian side. The official opening ceremony took place on June 8th, 1925 and included a light parade in Niagara Falls, New York and an international ceremony held in the middle of the Upper Steel Arch Bridge. Walter D’Arcy Ryan was the illuminating engineer and A.D. Dickerson who was his New York field assistant directed the scintillator. with information from American Technological Sublime by David E.

Youth sport organizations depend on volunteers to coach the teams in the organization. The purpose of this quantitative study was to develop a further understanding of volunteer coach retention in youth sport. The data was collected through a quantitative questionnaire which used close-ended and Likert-scale questions. The questionnaire collected data on the modified Model of Volunteer Retention in Youth Sports, reasons to withdraw from coaching and human resource management. There were 126 surveys collected from members of the three largest youth sport associations in the town of Aylmer, Ontario. The study found that Person-Task fit was the best predictor of volunteer coach retention as it significantly correlated to one’s intention to continue coaching (p< 0.01). Furthermore, additional reasons were found to explain withdrawal from coaching - if one’s child stops playing the sport or if coaching is too time consuming. The retention of volunteer coaches in youth sport organizations requires a multi-dimensional approach in understanding how to best retain volunteer coaches.

The study of peers as an influence on sport participation has received minimal exploration. The purpose of this cross-sectional study was to determine how peer created motivational climates (task-involved and ego-involved) impact positive and negative affective states of intramural sport participants post-participation. Three hundred and fifteen intramural sport participants (N=315) at a Canadian university completed a questionnaire after participating in their intramural sport. Hierarchical regression analyses and MANCOVAs were used to examine the effects of peer motivational climates on positive and negative affect. Results revealed that task-involved peer climates are more conducive of positive affective states post-participation whereas ego-involved climates result in lesser positive affective states and more negative affective states. Teams that promote improvement and effort instead of intra-team competition and conflict will have more positive recreational sport experiences. Future research should explore other psychological outcomes that can result from peer created motivational climates in recreational sport team settings.

A collective decision problem is described by a set of agents, a profile of single-peaked preferences over the real line and a number k of public facilities to be located. We consider public facilities that do not su¤er from congestion and are non-excludable. We provide a characterization of the class of rules satisfying Pareto-efficiency, object-population monotonicity and sovereignty. Each rule in the class is a priority rule that selects locations according to a predetermined priority ordering among interest groups. We characterize each of the subclasses of priority rules that respectively satisfy anonymity, hiding-proofness and strategy-proofness. In particular, we prove that a priority rule is strategy-proof if and only if it partitions the set of agents into a fixed hierarchy. Alternatively, any such rule can be viewed as a collection of fixed-populations generalized peak-selection median rules (Moulin, 1980), that are linked across populations, in a way that we describe.

Questions : Cette thèse visait à répondre à deux questions fondamentales : 1) Est-ce que les athlètes qui présentent un historique de commotions cérébrales du sport en conservent des effets délétères à long terme? ; et 2) Est-ce que les effets néfastes des commotions cérébrales récurrentes sur le fonctionnement tant cognitif que moteur sont cumulatifs? Devis expérimental : À l’aide d’un plan d’investigation double-cohorte réalisé avec un groupe d’athlètes évoluant au niveau universitaire et un autre formé d’anciens athlètes universitaires testés plus de trois décennies plus tard, les quatre études qui composent cette thèse ont employé des méthodes raffinées d’investigation des fonctions cognitives et motrices pour en déceler des atteintes persistantes. Méthodologie : Les potentiels évoqués cognitifs ainsi que les tests neuropsychologiques ont permis de sonder le fonctionnement cognitif de ces athlètes alors que la stimulation magnétique transcrânienne, une plateforme de force permettant de mesurer la stabilité posturale ainsi qu’un système d’enregistrement tridimensionnel des mouvements rapides alternatifs ont servi à l’évaluation de l’intégrité du système moteur. Résultats : Cette thèse a permis de déceler des altérations persistentes et cumulatives des fonctions cognitives et motrices. De plus, ces subtiles atteintes observées chez les jeunes athlètes, affectant essentiellement des marqueurs neurophysiologiques sous-cliniques du fonctionnement cognitif et moteur, s’étaient accentuées chez les anciens athlètes universitaires qui montraient un déclin quantifiable tant des fonctions cognitives que motrices. Discussion : Ces résultats suggèrent d’une part que les commotions cérébrales du sport entraînent des altérations cognitives et motrices chroniques qui s’accentuent en fonction du nombre de commotions cérébrales subies. D’autre part, les effets délétères des commotions cérébrales du sport sur le fonctionnement cognitif et moteur combinés à ceux associés au processus de vieillissement entraînent un déclin cognitif et moteur quantifiable en comparaison aux anciens athlètes n’ayant jamais subi de commotions cérébrales.

Cette thèse lève en partie le voile sur l’histoire des sports féminins au Québec de 1919 à 1961, soit de l’âge d’or des sports féminins au Canada jusqu’à l’adoption de la Loi sur la condition physique et le sport amateur par le gouvernement fédéral. Elle montre comment les rapports de genre ont été re/produits dans les sports féminins en étudiant les discours et les pratiques, tout en portant une attention particulière à l’influence qu’exercent l’appartenance de classe, l’ethnicité et la religion sur les sports féminins. L’analyse se penche d’abord sur les discours des médecins, des professeurs d’éducation physique et des clercs de l’Église catholique pour étudier les prescriptions qu’ils ont formulées à l’égard de la participation sportive des femmes. Les idées de deux Montréalaises, Myrtle Cook et Cécile Grenier, sont ensuite examinées pour montrer comment elles contestent les discours dominants. Enfin, les pratiques sportives des femmes dans deux centres sportifs montréalais, soit la Palestre nationale et le Young Women’s Christian Association, ont été étudiées de manière détaillée afin de mettre en lumière les différences, mais aussi certaines similitudes, entre l’organisation des sports féminins dans les communautés francophones et anglophones de la ville. Cette thèse met en évidence les tensions qui découlent des rapports de genre, de classe, d’ethnicité et de l’appartenance religieuse, et qui sont présentes à la fois dans les discours et les pratiques. Comme ailleurs en Amérique du Nord et même ailleurs en Occident, les discours dominants au Québec ne sont pas univoques, alors que des vues divergentes les contestent et que les pratiques sont plurielles. Tout en s’inscrivant dans le mouvement plus large d’accès des femmes aux sports en Occident, les discours et les pratiques observables à Montréal s’en distinguent, notamment par la forte influence de l’Église catholique et par les tensions ethniques. Le Québec est donc un cas d’espèce tout indiqué pour mettre en lumière la complexité de la re/production des rapports de genre à travers l’analyse des sports féminins, l’étude de ce champ constituant en même temps une avenue de recherche fort stimulante pour mieux saisir l’entrée de la province dans la modernité.
