Through our own eyes : a study of healing as elucidated by the narratives of First Nations individuals

Loft, Michael. January 2007 (has links)
For some Aboriginal people, healing is a relatively new word that seems to have emerged and taken on a life of its own only after the 1990 Mohawk Crisis and the ensuing Royal Commission on Aboriginal Peoples (RCAP, 1996). In spite of the massive 4000-page RCAP report, some mainstream authorities (Brasfield, 2001) still believe that the meaning of Aboriginal healing has not been fully explained. In this study, an attempt will be made to widen the meaning of Aboriginal healing by examining ancient Haudenosaunee (People of the Longhouse) philosophy, historical cultural upheaval, and narratives from First Nations survivors of Indian residential schools and a Holocaust survivor. The results have shown a connection between Aboriginal healing and Canadian society. Healing can only occur if the wound is not continuously reopened such as when long-standing land claims remain unsettled, Indigenous language and culture programs are neglected, and a People are ignored.

Optimizing an Off-Grid Electrical System in Brochet, Manitoba, Canada

Bhattarai, Prasid Ram 26 August 2013 (has links)
Brochet is a remote, off-grid community located in Northern Manitoba, Canada. The existing diesel generating system is characterized by high economic and environmental costs. As the existing diesel generators are nearing the end of their operational lifespan, this study uses the HOMER model to determine an optimum electricity system design at Brochet that has high electrical reliability, least cost, and low emissions. Three potential power generation options were considered and evaluated, namely: 1) only diesel, 2) only wind, 3) a mix of both. The wind-diesel hybrid system performed best for all the evaluation criteria. While maintaining high reliability, this hybrid system design resulted in 19 % reduction in electricity cost, and 30 % reduction of CO2 when compared to the existing electricity system at Brochet. Thus, this study concludes that the wind-diesel hybrid system is the optimum electricity system design for Brochet and proposes this system replace the existing system.

Feasibility analysis of wood-biomass energy generation for the off-grid community of Brochet in North-west Manitoba, Canada.

Rahman, Rezaur 25 August 2014 (has links)
The feasibility of wood based energy plants in the off-grid Brochet community in Manitoba were analyzed by survey, interviews and document review in this research. Four areas were explored to assess the suitability of biomass energy generation, namely: the community’s perspective, resource assessment, technology availability, and cost attractiveness. Harvesting sufficient woody biomass from local wild fire burnt areas, in particular, as well as local green forests could be an appropriate and feasible option. A heat only plant is considered to be the best choice for biomass plant establishment in Brochet, followed by combined heat and power plants. A cost analysis showed that a biomass plant at Brochet is more economical than the current planned investment in the diesel power facility. The lack of resolve about who wants to run and pay for the operation and the uncertainty of the reliability of biomass technologies are two large barriers to biomass energy generation in the community. Overall, biomass energy generation options are promising to eliminate or reduce the use of fossil fuel in Brochet.

Bolagsstorlek och pecking order-teorin : Har företagsstorleken någon inverkan på hur väl företaget följer pecking order?

Tiagi, Tanzil Abbas, Hassani, Jawad January 2014 (has links)
Bakgrund: Pecking order-teorin är en av de viktigaste teorierna som används inom kapitalstruktur. Men vilken giltighet teorin har i det praktiska för företaget, är väldigt olika beroende på olika faktorer. En av dessa faktorer är företagets storlek. Tidigare forskning tyder på att pecking order förmågan varierar mellan företag av olika storlek. Vissa studier har kommit fram till att pecking order beteendet är mer giltigt hos små företag. Andra menar att det är större företag som är bättre på att följa pecking order teorin. Syfte: Studiens syfte är att se om företagets storlek har någon inverkan på hur väl ett företag följer pecking order. Teori: Viktiga teorier är kapitalstruktur, pecking order teorin, assymmetrisk information, företagsstorlek, tidigare forskning av Gonzalez och Gonzalez (2012) samt Agca och Mozumdar (2004). Metod: Studien genomförs med hjälp av en kvantitativ metod. Data för 45 företag på fem år har samlats in för åren 2008-2012, för att sedan beräkna och genomföra tolkningar. Slutsats: Företagsstorleken har en inverkan på hur väl svenska företag lever upp till pecking order teorin. Sambandet är positivt, och visar att ju större företaget är, desto bättre följer det pecking order.

Neugierde und Wettkampfsport : die Gründungsmotivation von Professoren

Sass, Enrico January 2013 (has links)
Ausgründungen aus der Wissenschaft (spin-offs) gehören zu den anspruchsvollsten Instrumenten des Wissens- und Technologietransfers. Die Initiatoren erfolgreicher Gründungsvorhaben sind oftmals engagierte Hochschullehrer, die nicht nur Anerkennung in der Scientific Community suchen, sondern ihre Forschungsergebnisse ebenso in anwendungsorientierte Produkte und Dienstleistungen überführen. Was treibt diese Wissenschaftler an? In welchem Zusammenhang steht die Gründungsmotivation mit der ursprünglichen wissenschaftlichen Motivation? Ist das Initiieren einer Ausgründung mehr als das Lösen eines herausfordernden Rätsels? Der vorliegende Artikel gibt eine Antwort auf diese Fragen und gewährt einen Einblick in die Gründungsmotivation von Hochschulprofessoren aus den Naturwissenschaften. Mit Hilfe einer qualitativen Untersuchung werden verschiedene Gründertypen gebildet.

Gate-Turn-Off thyristor commutation of DC machines : the development of a rotating DC machine with static commutation of armature coil current using Gate-Turn-Off thyristor devices

Karim, A. H. M. January 1986 (has links)
The thesis Is concerned with the development of a separately excited DC machine In which gate turn-off thyristor devices with their associated firing and protective circuits are used to provide the static commutation of armature coil current. The developed machine has Its armature winding with 24 tapping points located on the stator and Interconnected In "Lop" configuration. The Initiation of the conduction periods of armature switching devices Is defined by a digital control logic circuit. In conjunction with an Incremental rotary encoder which provides the necessary feedback Information relating to shaft speed and shaft angular position. This Is arranged such that, under normal running conditions of the machine, the axis of the radial field of the armature winding maintains the normal space-quadrature relationship with that of the main field winding, giving the optimal torque angle of 000. Provision Is made, however, within the digital control circuit for controlled departure of the armature switch tapping points from the quadrature axis positions, and the effect of this, In Improving commutation Is Investigated. The effect of Interpoles Is also explored. On the basis of the analysis carried out, a proposal Is made for the future development of the machine employing a reduced number of armature switching devices without the need for Interpole windings.
