'A Kind of Logic, A Kind of Dominant Logic': Navigating Colonialism, Honoring Black Mobility, and Thinking on Moving Through

My thesis thinks through the ways Newtonian logics require linear mobility in order to produce narratives of progress. I argue that this linear mobility, and the resulting logics, potentially erases the chaotic and non-linear motions that are required to navigate a colonial landscape. I suggest that these non-linear movements produce important critiques of the seeming stasis of colonial constructs and highlight the ways these logics must appear neutral and scientific in an attempt to conceal the constant and complex adjustments these frameworks require. In order to make room for these complex motions, I develop a quantum intervention. Specifically, I use quantum physics as a metaphor to think through the significance of black life, the double-consciousness ofland, and the intricate motions of sound. In order to put forth this intervention, I look at news coverage of Hurricane Katrina, Du Bois’s characterization of land in Souls of Black Folks, and the aural mobilities of blackness articulated in an academic discussion and interview about post- humanism.

Restrictions on Aliens in the United Kingdom, 1914-1919 : a Study of the Origins and Political Background of the Aliens Restrictions Acts of 1914 and 1919.

At first glance the Aliens Restriction Act of 1914, which was introduced and passed on the first day of World War One, seems a hasty and ill-prepared piece of legislation. Actually, when examined in the light of Arthur Marwick's thesis that war is a forcing house for pre-existent social and governmental ideas, it becomes clear that the act was not after all the product of hastily formed notions. In point of fact it followed the precedent of detailed draft clauses produced in 1911 by a sub-committee of the Committee of Imperial Defence established to consider the treatment of aliens in the event of war. Indeed the draft clauses and the restrictions embodied in the 1914 act were strikingly similar to restrictions on aliens legislated in 1793. Hostility to aliens had been growing from 1905 to 1914 and this hostility blossomed into xeno-phobia on the outbreak of war, a crucial precondition for the specifically anti-enemy fears of the time. In 1919 the Aliens Restriction (Amendment) Bill was introduced into parliament to extend temporarily the provisions of the 1914 act thus permitting the Home Secretary to plan permanent, detailed legislation. Two minority groups of MPs with extreme views on the treatment of aliens were prominent in the debates on this bill. The extreme Liberal group which advocated leniency in the treatment of aliens had little effect on the final form of the bill, but the extreme Conservative group, which demanded severe restrictions on aliens, succeeded in persuading the government to include detailed restrictions. Despite its allegedly temporary nature, the Aliens Restriction (Amendment) Act of 1919 was renewed annually until 1971.

The Ontario-Manitoba Boundary Dispute

The powers of the General Government are so much greater than those of the United States in its relations with the Local Governments, that the central power must win. The next quarter century was marked by struggle, or rather a series of struggles, between the Dominion Government and those of the various provinces with as a general rule contrary to Macdonal's expectations, the latter proving successful. Ontario was the most consistent opponent of centralizing tendencies; her most notably victory was scored in what is known as the Ontario-Manitoba Boundary Dispute. It is out intention to deal with this question primarily as a phase of post-Confederation politics.

The Significance of the Disputed Territory in Bechuanaland 1887-1893

British Imperial policy in Southern Africa in the last three decades of the nineteenth century oscillated between two extremes. It began in the early 1870's with Lord Kimberley's attempt to effect confederation as a means of devolving Imperial responsibility and expenditure. It ended in 1899 with Britain's active intervention against the Boers. For most of the remaining years of those decades a middle course was adopted while the British Government struggled to reconcile its diverse political interests. Strategy, supremacy, economy, humanitarianism, and recognition of colonial aspirations were all at one time or another, in varying degrees, motivating forces behind Imperial policy. Many historians have pointed out how incompatible many of these ends were and how the attempt to pursue them all at once almost inevitably ended in at least one of them being sacrificed on the way. This study focusses on a relatively minor problem over a period of about seven years. It attempts to show how the British Government tried to reconcile, in this case, the predominant motives of economy and supremacy. The problem of the Disputed Territory now seems like a small fish in a big ocean because non the great hopes and fears that it raised were ever realized. But the anticlimactic nature of the outcome of events should not be allowed to conceal two important points: first, that the problem loomed large at the time in the eyes of the Imperial Government; and second, that in the case of its policy towards the Disputed Territory, the Government gained a greater degree of success in trying to reconcile seemingly incompatible ends than it did in many other instances.

Recent Armenian Developments

The War has brought us into a close relation with Armenia. The annihilation of her people in 1915 and 1916 aroused universal sympathy. For the most of us Armenia, hitherto, had been relegated to a position of partial obscurity in the Near East. We were acquainted with the fact that they had suffered persecution beore at Turkish hands but an indifference born of unfamiliarity with her history, customs and people still continued with us. However much the gulf separating ourselves and these people has been narrowed by the war it is only by an actual journey into their life past and present that we can ever come into a full appreciation of a people who despite persecution and oppression are potentially fine citizens.

Emerging From the Shadows : the Life of Captain John (Deserontyou), Circa 1742-1811, Founder of the Bay of Quinte Mohawk Village

This thesis is a biographical examination of the life of Mohawk leader Deserontyou (Captain John) and covers the years from the 1730's up to, and briefly following, 1811. The social, economic and political position of the Mohawk people and Deserontyou's position within the Fort Hunter community prior to the Revolution are addressed first. The Revolutionary War years are then covered with emphasis placed on Deserontyou's military role, the unpleasant conditions at Lachine and the painful reality for the Mohawk people in the aftermath of Britain's defeat. The post-war settlement on the Bay of Quinte is then explored, including the difficulties that Deserontyou experienced with the land, with the British Government, and with his own people. The documents upon which this examination are based come from many primary collections including: The Draper Manuscripts, the Haldimand Papers, the Stuart Papers, Ontario Lands & Forest Survey Records, the Society for the Propagation of the Gospel in Foreign Parts, Episcopal Records, the Bell Papers, the File Collection, the Claus Papers and Indian Affairs Papers.

Defences of the Niagara Frontier (1764-1870) : An Historical Survey of Fort George, Fort Erie & Fort Mississauga

The intention of the Niagara Parks Commission to undertake restorations of Fort George, Fort Mississauga and Fort Erie has inspired this survey. The aim has not been to create an historical narrative - so many already exist - but rather to present an accurate description of the original appearance, structure and design of each of the Niagara Forts. This it is hoped may be of some practical assistance to those in charge of the actual work of restoration. In the case of Fort Mississauga which was maintained as a military post until 1857, vary complete information has been available. Fort George and Fort Erie were abandoned for military purposes after the War of 1812 and fewer plans and contemporary accounts have survived. While the work of research, involving the collection of every possible plan of the works and every drawing of their appearance as well as the piecing together of material, has been more difficult in the case of the latter forts, it is felt that the essential information has been secured. The use of a number of military terms in the description of the fortifications has been unavoidable and a glossary of these is included on page 66. The list of plans and illustrations is as complete as possible.

The Financialization of Food: An Inquiry into the 2008-2011 Food Price Spikes

This dissertation investigates the question: has financial speculation contributed to global food price volatility since the mid 2000s? I problematize the mainstream academic literature on the 2008-2011 food price spikes as being dominated by neoclassical economic perspectives and offer new conceptual and empirical insights into the relationship between financial speculation and food. Presented in three journal style manuscripts, manuscript one uses circuits of capital to conceptualize the link between financial speculators in the global north and populations in the global south. Manuscript two argues that what makes commodity index speculation (aka ‘index funds’ or index swaps) novel is that it provides institutional investors with what Clapp (2014) calls “financial distance” from the biopolitical implications of food speculation. Finally, manuscript three combines Gramsci’s concepts of hegemony and ‘the intellectual’ with the concept of performativity to investigate the ideological role that public intellectuals and the rhetorical actor the market play in the proliferation and governance of commodity index speculation. The first two manuscripts take an empirically mixed method approach by combining regression analysis with discourse analysis, while the third relies on interview data and discourse analysis. The findings show that financial speculation by index swap dealers and hedge funds did indeed significantly contribute to the price volatility of food commodities between June 2006 and December 2014. The results from the interview data affirm these findings. The discourse analysis of the interview data shows that public intellectuals and rhetorical characters such as ‘the market’ play powerful roles in shaping how food speculation is promoted, regulated and normalized. The significance of the findings is three-fold. First, the empirical findings show that a link does exist between financial speculation and food price volatility. Second, the findings indicate that the post-2008 CFTC and the Dodd-Frank reforms are unlikely to reduce financial speculation or the price volatility that it causes. Third, the findings suggest that institutional investors (such as pension funds) should think critically about how they use commodity index speculation as a way of generating financial earnings.

Essays in dynamic optimal taxation: working experience, unemployment scarring and poverty

This thesis investigates the design of optimal tax systems in dynamic environments. The first essay characterizes the optimal tax system where wages depend on stochastic shocks and work experience. In addition to redistributive and efficiency motives, the taxation of inexperienced workers depends on a second-best requirement that encourages work experience, a social insurance motive and incentive effects. Calibrations using U.S. data yield higher expected optimal marginal income tax rates for experienced workers for most of the inexperienced workers. They confirm that the average marginal income tax rate increases (decreases) with age when shocks and work experience are substitutes (complements). Finally, more variability in experienced workers' earnings prospects leads to increasing tax rates since income taxation acts as a social insurance mechanism. In the second essay, the properties of an optimal tax system are investigated in a dynamic private information economy where labor market frictions create unemployment that destroys workers' human capital. A two-skill type model is considered where wages and employment are endogenous. I find that the optimal tax system distorts the first-period wages of all workers below their efficient levels which leads to more employment. The standard no-distortion-at-the-top result no longer holds due to the combination of private information and the destruction of human capital. I show this result analytically under the Maximin social welfare function and confirm it numerically for a general social welfare function. I also investigate the use of a training program and job creation subsidies. The final essay analyzes the optimal linear tax system when there is a population of individuals whose perceptions of savings are linked to their disposable income and their family background through family cultural transmission. Aside from the standard equity/efficiency trade-off, taxes account for the endogeneity of perceptions through two channels. First, taxing labor decreases income, which decreases the perception of savings through time. Second, taxation on savings corrects for the misperceptions of workers and thus savings and labor decisions. Numerical simulations confirm that behavioral issues push labor income taxes upward to finance saving subsidies. Government transfers to individuals are also decreased to finance those same subsidies.

The effects of sympatry on patterns of bill morphology between closely related species of birds, worldwide

When closely related species co-occur in sympatry, they face a significant challenge. They must adapt to the same local conditions in their shared environment, which favours the convergent evolution of traits, while simultaneously minimizing the costs of competition for shared resources that typically favours the divergent evolution of traits. Here, we use a comparative sister lineage approach to test how most species have responded to these conflicting selection pressures in sympatry, focusing on a key ecological trait: the bill morphology of birds. If similar bill morphologies incur fitness costs due to species interactions, then we predicted that the bill morphologies of closely related species would differ more in sympatry compared with allopatry. Alternatively, if similar bill morphologies incur fitness benefits due to local adaptation, then we predicted that the bill morphologies would be more similar in sympatry compared with allopatry. We used museum specimens to measure five aspects of bill (maxilla) morphology – depth, length, width, side shape, and bottom shape – in diverse bird species from around the world to test our alternative hypotheses. We found support for both divergent evolution and convergent evolution (or trait retention) in one ecological trait: closely related sympatric species diverged in bill depth, but converged in side shape. These patterns of bill evolution were influenced by the genetic distance between closely related sister taxa and the geographic distance between allopatric lineages. Overall, our results highlight species interactions as an important mechanism for the evolution of some (bill depth), but not all (bill shape), aspects of bill morphology in closely related species in sympatry, and provide strong support for the bill as a key ecological trait that can adapt in different ways to the conflicting challenges of sympatry.

Investigation of Performance Enhancements for a Liquid-Desiccant Solar Air-Conditioner

Thermally driven liquid-desiccant air-conditioners (LDAC) are a proven but still developing technology. LDACs can use a solar thermal system to reduce the operational cost and environmental impact of the system by reducing the amount of fuel (e.g. natural gas, propane, etc.) used to drive the system. LDACs also have a key benefit of being able to store energy in the form of concentrated desiccant storage. TRNSYS simulations were used to evaluate several different methods of improving the thermal and electrical coefficients of performance (COPt and COPe) and the solar fraction (SF) of a LDAC. The study analyzed a typical June to August cooling season in Toronto, Ontario. Utilizing properly sized, high-efficiency pumps increased the COPe to 3.67, an improvement of 55%. A new design, featuring a heat recovery ventilator on the scavenging-airstream and an energy recovery ventilator on the process-airstream, increased the COPt to 0.58, an improvement of 32%. This also improved the SF slightly to 54%, an increase of 8%. A new TRNSYS TYPE was created to model a stratified desiccant storage tank. Different volumes of desiccant were tested with a range of solar array system sizes. The largest storage tank coupled with the largest solar thermal array showed improvements of 64% in SF, increasing the value to 82%. The COPe was also improved by 17% and the COPt by 9%. When combining the heat recovery systems and the desiccant storage systems, the simulation results showed a 78% increase in COPe and 30% increase in COPt. A 77% improvement in SF and a 17% increase in total cooling rate were also predicted by the simulation. The total thermal energy consumed was 10% lower and the electrical consumption was 34% lower. The amount of non-renewable energy needed from the natural gas boiler was 77% lower. Comparisons were also made between LDACs and vapour-compression (VC) systems. Dependent on set-up, LDACs provided higher latent cooling rates and reduced electrical power consumption. Negatively, a thermal input was required for the LDAC systems but not for the VC systems.

Cultural Politics of Resilience in Kingston, Jamaica

Recently, resilience has become a catchall solution for some of the world’s most pressing ecological, economic and social problems. This dissertation analyzes the cultural politics of resilience in Kingston, Jamaica by examining them through their purported universal principles of adaptation and flexibility. On the one hand, mainstream development regimes conceptualize resilience as a necessary and positive attribute of economies, societies and cultures if we are to survive any number of disasters or disturbances. Therefore, in Jamaican cultural and development policy resilience is championed as both a means and an end of development. On the other hand, critics of resilience see the new rollout of resilience projects as deepening neoliberalism, capitalism and new forms of governmentality because resilience projects provide the terrain for new forms of securitization and surveillance practices. These scholars argue that resilience often forecloses the possibilities to resist that which threatens us. However, rather than dismissing resilience as solely a sign of domination and governmentality, this dissertation argues that resilience must be understood as much more ambiguous and complex, rather than within binaries such as subversion vs. neoliberal and resistance vs. resilience. Overly simplistic dualities of this nature have been the dominant approach in the scholarship thus far. This dissertation provides a close analysis of resilience in both multilateral and Jamaican government policy documents, while exploring the historical and contemporary production of resilience in the lives of marginalized populations. Through three sites within Kingston, Jamaica—namely dancehall and street dances, WMW-Jamaica and the activist platform SO((U))L HQ—this dissertation demonstrates that “resilience” is best understood as an ambiguous site of power negotiations, social reproduction and survival in Jamaica today. It is often precisely this ambiguous power of ordinary resilience that is capitalized on and exploited to the detriment of vulnerable groups. At once demonstrating creative negotiation and reproduction of colonial capitalist social relations within the realms of NGO, activist work and cultural production, this dissertation demonstrates the complexity of resilience. Ultimately, this dissertation draws attention to the importance of studying spaces of cultural production in order to understand the power and limits of contemporary policy discourses and political economy. 

#DressCodePM & Re-Framing The Niqab: News Sources, Hashtag Activism, and Media Representation

This thesis originates from my interest in exploring how minorities are using social media to talk back to mainstream media. This study examines whether hashtags that trend on Twitter may impact how news stories related to minorities are covered in Canadian media. The Canadian Prime Minister Stephen Harper stated the niqab was “rooted in a culture that is anti-women” on 10 March 2015. The next day #DressCodePM trended in response to the PM’s niqab remarks. Using network gatekeeping theory, this study examines the types of sources quoted in the media stories published on 10 and 11 March 2015. The study’s goal is to explore whether using tweet quotes leads to the representation of a more diverse range of news sources. The study compares the types of sources quoted in stories that covered Harper’s comments without mentioning #DressCodePM versus stories that mention #DressCodePM. This study also uses Tuen A. van Dijk’s methodology of asking “who is speaking, how often and how prominently?” in order to examine whose voices have been privileged and whose voices have been marginalized in covering the niqab in Canadian media from the 1970s and until the days following the PM’s remarks. Network gatekeeping theory is applied in this study to assess whether the gated gained more power after #DressCodePM trended. The case study’s findings indicates that Caucasian male politicians were predominantly used as news sources in covering stories related to the niqab for the past 38 years in the Globe and Mail. The sourcing pattern of favouring politicians continued in Canadian print and online media on 10 March 2015 following Harper’s niqab comments. However, ordinary Canadian women, including Muslim women, were used more often than politicians as news sources in the stories about #DressCodePM that were published on 11 March 2015. The gated media users were able to gain power and attract Canadian Media’s attention by widely spreading #DressCodePM. This study draws attention to the lack of diversity of sources used in Canadian political news stories, yet this study also shows it is possible for the gated media users to amplify their voices through hashtag activism.

International Capital Flows and Monetary Policy Spillovers

This dissertation examines the drivers and implications of international capital flows. The overarching motivation is the observation that countries not at the centre of global financial markets are subject to considerable spillovers from centre countries, notably from their monetary policy. I present new empirical evidence on the determinants of the observed patterns of international capital flows and monetary policy spillovers, and study their effect on both financial markets and the real economy. In Chapter 2 I provide evidence on the determinants of a puzzling negative correlation observed between productivity growth and net capital inflows to developing and emerging market economies (EMEs) since 1980. By disaggregating net capital inflows into their gross components, I show that this negative correlation is explained by capital outflows related to purchases of very liquid assets from the fastest growing countries. My results suggest a desire for international portfolio diversification in liquid assets by fast growing countries is driving much of the original puzzle. In the reminder of my dissertation I pivot to study the foreign characteristics that drive international capital flows and monetary policy spillovers, with a particular focus on the role of unconventional monetary policy in the United States (U.S.). In Chapter 3 I show that a significant portion of the heterogeneity in EMEs' asset price adjustment following the quantitative easing operations by the Federal Reserve (the Fed) during 2008-2014 can be explained by the degree of bilateral capital market frictions between these countries and the U.S. This is true even after accounting for capital controls, exchange rate regimes, and domestic monetary policies. Chapter 4, co-authored with Michal Ksawery Popiel, studies unconventional monetary policy in a small open economy, looking specifically at the case of Canada since the global financial crisis. We quantify the effect Canadian unconventional monetary policy shocks had on the real economy, while carefully controlling for and quantifying spillovers from U.S. unconventional monetary policy. Our results indicate that the Bank of Canada's unconventional monetary policy increased Canadian output significantly from 2009-2010, but that spillovers from the Fed's policy were even more important for increasing Canadian output after 2008.
