Community, Complexity, and Collapse
The city-state of Minanha, located in west central Belize, reached its zenith and most culturally complex stage by the Late Classic period, 675-810 AD. Only a century later, its royal court “collapsed”. The Contreras Valley is a small farming community located in a settlement zone south of Minanha. Decades of research at Minanha and the analysis of artifact frequencies from commoner households allow for a better understanding of the intra- and inter-community social practices occurring at the site of Contreras Valley and within the greater Minanha area. An Archaeology of Communities as well as Resilience Theory frameworks are utilized to explore the integrative social, political, and economic strategies of this commoner population. These theories are used to better understand the developmental history of the royal court from the perspective of the peripheral commoners, who sustained a population while the royal court disintegrated. Furthermore, this thesis focuses on the intersection of resilience and communities, and how the Contreras Valley experienced phases of resilience as well as vulnerability throughout its history. The resilience of this group of individuals will generate an increased cognizance of how a community copes with and continues to thrive in a climate of political chaos and instability.

Childhood diet and feeding practices at Apollonia
This study analyses deciduous dental pathology and stable carbon and nitrogen isotopes to investigate the relationship between dietary composition, feeding practices, and oral health in a subadult skeletal sample from the Greek colonial site of Apollonia Pontica, Bulgaria (5th to 3rd century BC). Stable isotope analysis of 74 bone collagen samples indicates that weaning began between the ages of 6 months and 1 year, and was complete by the age of 4. The stable isotope data are consistent with a diet of primarily terrestrial C3 resources. The deciduous dentitions of 85 individuals aged between 8.5 months and 10.5 years were examined for evidence of a number of pathological conditions. The presence of dental caries, calculus, occlusal tooth wear and an abscess indicate that foods introduced early in life affected the oral health of these individuals. Overall, the deciduous dental data correlate well with the stable isotope data and ancient textual sources regarding infant and childhood dietary composition and feeding practices. Author Keywords: breastfeeding, deciduous dentition, dental pathology, stable carbon and nitrogen isotopes, weaning
Holocene Resource Exploitation
This study uses the zooarchaeological record to examine the range of activities represented in Late Archaic period samples excavated from Jacob's Island -1B, in the Trent-Severn Waterway region in Ontario. Radiocarbon dates from sixteen features were used to establish a chronology of site use and occupation. The faunal remains analyzed in this study were recovered from seven dated mortuary features associated with human remains. The results of the faunal analysis suggest that Canis lupus familiaris was the primary species interred at Jacob's Island-1B. Small rodents, specifically Tamias striatus were also found in high abundance and are possibly the result of natural burrowing disturbances. Red ochre staining and low levels of burning were identified. Comparisons with other contemporaneous sites in the region indicate some variation in species composition. It is suggested that Canis lupus familiaris was associated with ritual and mortuary activities at Jacob's Island-1B.

Commonality of Enemies
Carlism and anarchism were revolutionary social movements that acquired significant popular support during the most intensive period of modernization in Spain (mid 19th to mid 20th centuries). It was noted but not well explored by contemporaries and historians that these enemies were similar in their hostility towards modernization and in their intense idealism. This thesis compares the two movements in order to determine the nature of their commonality and what this suggests about ideological enemies. A range of sources were consulted, including scholarship on modern Spain, biographical information on individuals who converted from Carlism to anarchism and contemporary print media. It was concluded that they were produced by the same destabilizing processes of disentailment and industrialization, which drew the working classes towards proposals that would have otherwise seemed implausibly utopian. The thesis further suggests that they were uniquely idealistic, in that they put moral integrity before the success of their cause. Author Keywords: anarchism, Carlism, enemy other, modernization, Modern Spain, social movements
Supercritical Water Chemistry
Supercritical water (SCW) exhibits unique properties that differentiates it from its low temperature behaviour. Hydrogen bonding is dramatically reduced, there is no phase boundary between liquid and gaseous states, heat capacity increases, and there is a drastic reduction of the dielectric constant. Efforts are underway for researchers to harness these properties in the applications of power generation and hazardous waste destruction. However, the extreme environment created by the high temperatures, pressures and oxidizing capabilities pose unique challenges in terms of corrosion not present in subcritical water systems. Molecular Dynamics (MD) simulations have been used to obtain mass transport, hydration numbers and the influence on water structure of molecular oxygen, chloride, ammonia and iron (II) cations in corrosion crevices in an iron (II) hydroxide passivation layer. Solvation regimes marking the transitions of solvation based versus charge meditated processes were explored by locating the percolation thresholds of both physically and hydrogen bonded water clusters. A SCW flow through reactor was used to study hydrogen evolution rates over metal oxide surfaces, metal release rates and the kinetics for the oxidation of hydrogen gas by oxygen in SCW. Insights into corrosion phenomena are provided from the MD results as well as the experimental determination of flow reactor water and hydrogen chemistry.

Alone in Power
The thesis uses three case studies of President Nixon’s foreign policy in South-east Asia to analyze presidential domestic-making. The theoretical concept of personality politics is used to analyze the Nixon administration and foreign policy. Nixon’s secretive nature combined with his mistrust of the press and bureaucracy to create an office structure that restricted the involvement and notification of others of his foreign policy. This thesis also takes into account the domestic climate that Nixon was operating within, including significant antiwar opposition, an adversarial media, and an ideologically opposed bureaucracy. Nixon’s foreign policy was ultimately the result of a perfect storm of factors. The president’s natural penchant for secrecy, along with his mistrust of the press and bureaucracy, combined with the American political environment that was in many instances ideologically set against him, also helped shape his foreign policy.

Rewiring the State
ABSTRACT Rewiring the State: The Privatization of Information Technology in the Ontario Public Service (1972-2003) David Rapaport Senior managers in the Ontario Public Service (OPS) and neo-liberal public policy advocates rationalize the privatization of Information Technology (IT) as an organizational quest for new efficiencies, specifically efficiencies imported from market economies. The findings of the research for this study indicate that IT privatization frequently results in inefficiencies, dependencies and a loss of core skills. The explanation for widespread IT privatization must be sought elsewhere. This study researches and depicts two related IT developments. The first development is the evolution of IT privatization from the earlier practice of body-shopping, i.e. the hiring on contract of IT consultants to the more complex public private partnership. This evolution is a reflection of the maturation of privatization. Body-shopping informs the alienation of IT skills from the public sector, the shaping of a labour hierarchy based on skills distribution, and the foundation for the public-private partnership. The second development, the evolution of OPS management attitudes towards IT privatization, is a reflection of growing neo-liberal hegemony. Archival research indicates middle management disdain towards excessive IT privatization in the early 1980's; particularly its high costs, loss of skills and growing dependency on external private sources. By the ii late 1990's, parliamentary committee transcripts indicate IT management acceptance of more excessive IT privatization. As neo-liberal practice became more accepted and as governments and central ministries pressured line ministries through budgetary and organizational controls, IT managers accepted their new roles as authors of RFP's and tenders of public sector work. The IT service providing industry gladly bid on contracts and acquired the new skills required for future IT projects, exacerbating the provision/dependency cycle. Furthermore, the new technologies provided an ideological smokescreen of technological necessity to conceal the market forces that promoted and benefitted from IT privatization. "Why do managers in the Ontario Public Service privatize the production of Information Technology systems?" The dissertation has two tasks when answering this central question. First, it must refute the efficiency arguments. Second, it must formulate an answer within the context of neo-liberal state transformation, new investment strategies of IT service providing corporations and a restructured IT labour hierarchy.

Class Struggle and Solidarity in Neo-Liberal Times
The lengthy and raucous 1986 Gainers meatpacking plant strike in Edmonton, Alberta was one of the most important events in recent Alberta labour history. In the midst of the economic crisis of the 1980s and the rise of neo-liberal ideas, the strike marked a backlash by both the labour movement and ordinary citizens against attacks on workers and unions. Characterized by widely covered picket line violence, repressive police and court actions, and government unresponsiveness, the strike generated massive solidarity within and beyond the labour movement. This solidarity originated in a rejection of the neo-liberal new reality of Alberta typified by high unemployment, anti-union laws and practices, and lack of government welfare support, and it generated a provincial change the law campaign, national boycott, and rising class consciousness. The working class mobilization during the Gainers strike was a watershed for the Alberta labour movement.

Effect of Nitrosative Stress on Heme Protein Expression and Localization in Giardia Intestinalis
The parasitic protist Giardia intestinalis has five heme proteins: a flavohemoglobin and several isotypes of cytochrome b5. While the flavohemoglobin has a role in counteracting nitric oxide, the functions of the cytochromes (gCYTb5s) are unknown. In this study, the protein level and cellular localization of three gCYTB5 isotypes (gCYTb5-I, II and III) and flavohemoglobin were examined in Giardia trophozoites exposed to three nitrosative stressors at two different concentrations: nitrite (20 mM, 0.5 mM); GSNO (2 mM, 0.25 mM) and DETA-NONOate (2 mM, 0.05 mM). An increase in protein levels was observed for gCYTb5-II with all stressors at both concentrations. However, the effects of these nitrosative stressors on gCYTb5-I and III were inconclusive due to the variation among the replicates and the poor detection of gCYTb5- III on western blots. The protein level of the flavohemoglobin also increased in response to the three stressors at the low concentrations of stressors that were tested. Only the cellular localization of gCYTb5-I changed in response to nitrosative stress, where it moved from the nucleolus to the nucleus and cytoplasm. This response was extremely sensitive and occurred at the lower doses of the three stressors, suggesting that gCYTb5-I may be involved in a nucleolar- based stress response. Author Keywords:
“A City is Not a Place of Origins”
This thesis explores the work of Black queer authors who write and reproduce cities in their texts. James Baldwin and Dionne Brand create knowable and readable spaces of the cities in which they write. By studying the work of these two authors, this thesis seeks to understand how Black queer people navigate city spaces, and how Black queer authors create a literary imaginary about the cities in which their novels are set. Thus, the cities of New York and Toronto become knowable sites through the novels of Dionne Brand and James Baldwin. Using Black queer theory, Black diaspora theory, and Black literary theory, this thesis engages with the novels, essays, and interviews of James Baldwin and Dionne Brand to determine that urban spaces are both liberatory and traumatic for Black queer people. Author Keywords: Baldwin, Black Queer Studies, Black Women, Brand, Diaspora Studies, Lesbian
Enhancing interpretive trails with technology
Enhancing interpretive trails with smartphone technology may enrich the visitor’s educational experience by stimulating deeper engagement and enjoyment that will improve immediate knowledge and help promote the development of environmental literacy. This connection between technology and environmental education can only be considered successful if enhanced enrichment and educational value is found in the integration. Currently there is a substantial gap in research on the incorporation of technology into an interpretive trail experience. For this study, information on the local fauna and flora was produced and linked to Quick Response Codes (QR codes) installed along an outdoor trail. The QR codes were designed to be read using the participant’s personal smartphone. Immediately after completing the trail participants could volunteer to describe their smartphone-led experience through a self-administered cross-sectional questionnaire offered in hard copy at the study site. A non-experimental quantitative research methodology was employed to evaluate the survey data and determine the educational and enjoyment value of the experience. This research is of potential benefit to educators of science, technology and the environment. The research may also assist parks and recreation facilities wishing to offset the costs of building and maintaining traditional interpretive trails by eliminating the need for the printing of booklets, maps and signage. Author Keywords: education, environment, interpretive trails, science, smartphone technology
Technology of Consent
The 1980s in the United States have come into focus as years of extensive ideological and socioeconomic fracture. A conservative movement arose to counter the progressive gains of previous decades, neoliberalism became the nation’s economic mantra, and détente was jettisoned in favour of military build-up. Such developments materialized out of a multitude of conflicts, a cultural crisis of ideas, perspectives, and words competing to maintain or rework the nation’s core structures. In this dissertation I argue that alongside these conflicts, a crisis over technology and its ramifications played a crucial role as well, with the American public grasping for ways to comprehend a nascent technoculture. Borrowing from Andrew Feenberg, I define three broad categories of popular conceptualization used to comprehend a decade of mass technical and social transformations: the instrumental view, construing technology as a range of efficient tools; the substantive view, insisting technology is an environment that determines its subjects; and a critical approach, which recognizes the capacity for technology to shape subjects, but also its potential to aid new social agendas. Using Feenberg’s categories as interpretive lenses, I foreground these epistemologies in three of the decade’s most popular formations of literary science fiction (sf), and describe the broader discourses they participated in: military sf is connected to military strategy and weapons development (instrumental), cyberpunk to postmodernism and posthumanism (substantive), and feminist sf to feminist theory and politics (critical). These were not just discursive trajectories, I claim, but vital contributors to the material construction of what Antonio Gramsci would call hegemonic and counterhegemonic formations. While the instrumental paradigm was part of the decade’s prevailing hegemonic make-up, substantive and critical discourses offered an alternative to the reality of cowboy militarism and unchecked technological expansion. By engaging with the decade’s texts—from There Will Be War to RoboCop to “A Cyborg Manifesto”—I hope to illuminate what I call the technology of consent, the significance of technological worldviews for modern technocultures, where such views are consented to by subaltern groups, and at the same time the existence of consent itself as a kind of complex social technology in the first place.
