Through a qualitative analysis of messages posted on the micro-blogging application, Twitter, and qualitative research interviews with people from Egypt and the United States who were active on Twitter during the eighteen day Egyptian Revolution in 2011, this study considers why Dr. Theda Skocpol’s theory of revolution proffered in States and Social Revolutions (1979) does not work in the case of the Egyptian Revolution. Skocpol asserts that a weakening of the state vis-à-vis a dominant class within the state or other states is a necessary precondition for revolution. By examining Twitter as a mechanism through which on-the-ground activists in Egypt were able to circumvent repressive state structures and “jump-scales” to a transnational configuration of resistance, this thesis asserts that emergent technologies complicate Skocpol’s assertion that states must be weakened politically and financially prior to the execution of a successful social revolution. / text

In 2011, Calgary, Alberta based Borealis Geopower bought the geothermal rights to the Canoe Reach arm of Kinbasket Lake, near Valemount, British Columbia. New to Canada, a pilot project of a 2 megawatt geothermal power facility will begin within the next five years. The project is a positive addition to the area, as it is a non-polluting energy source with an effluent of clean hot water. This thesis proposes a maximization of this energy source by combining the power facility with an education center and bathing facility. Included in this bathing experience are ancillary cabins and paths to promote the users’ interaction and enjoyment of the project and landscape. Finally, this thesis develops a material strategy, choreographing the visitors’ experience of the geothermal resource within the site’s mountainous topography.

his thesis is a discussion on the affective politics of images, with attention given to the communities and forms of citizenship they create, both digital and real, and their role in contemporary revolutions in the Middle East/North African Region. Employing Ariella Azoulay's (2008) theoretical framework of a civil contract of photography, this thesis locates and examines how a “citizenship of photography” is mobilized through current trends of citizen photojournalism and communication technology. By exploring the citizenship and community building potential of images, digital and real, an account of the revolutionary possibilities of images is formed. Drawing on recent scholarship and theoretical frameworks in the field of visual studies, media studies, and citizenship, this thesis develops a complex narrative of how images become iconic, connect individuals, and become an integral component in contemporary revolutionary change.

To evaluate the impact of reduced truck tire pressure on strain response of low volume spring-restricted roads, research was conducted on two instrumented pavement sections in Manitoba, Canada. Tire pressure control systems tests were carried out at the sections in spring and fall 2009. Measured maximum tensile strain at the bottom of asphalt layer decreased by 15-20% when tire pressure was reduced by 50%. Measured strain at the bottom of asphalt layer in fall is about 50% less than in spring. The effects of gauge orientation, truck speed, and tire offset from the strain gauge were also analyzed. A finite element model with static load was developed and verified. The bearing capacity is lower in spring than in normal condition for flexible pavements subject to deep frost action. Reduced tire pressure is effective to reduce bottom up failure of the pavement, and is less effective to prevent rutting.

This thesis examines the spillover effects of armed conflicts on trade in neighboring countries. The empirical results, obtained by using a rich dataset on trade and conflict for 168 countries during the 1950-2011 period, and thus including the onset of the Arab Spring, show that conflict disrupts the trade of neighboring countries, even though they are not directly involved in any conflict. These spillovers are strongest one year after the onset of the conflict, thus suggesting that the negative effects of regional war on trade are lagged rather than contemporaneous, while they also increase the more violent the conflict is. When conflict in secondary neighbors, defined as countries that are not directly contiguous yet closer than 250km to any country in the trading-pair, is introduced the results are unclear as a majority of the estimates are insignificant and not robust to different model specifications.

This thesis reports the results obtained, and conclusions made regarding research into the hydrochemistry of a small impounded karst area in southeastern Australia. Water samples were collected from a variety of sites over a period of approximately six years and include samples that are representative of baseflow (drought conditions) and flood (high flow conditions) the two extremes of the flow regime. Four distinct water types were found to be associated with the karst spring and cave water sites sampled. In terms of physical, chemical and computed parameter values these have been classed as TYPE 1 water (median parameter values similar to those noted for the surface stream sites sampled with catchments of non-carbonate material); TYPE 2 water (catchment predominantly of limestone); TYPE 3 water (catchment predominantly of dolomite); TYPE 4 water (high median chemical concentrations). Spatial variation within the study area is considerable and intrinsic factors such as catchment lithology, the residence time of recharge, aspect and vegetation cover are the major natural controls in determining physical and chemical characteristics.
