Item Art, Archaeology, and the Museum: The Place and Value of Classical Antiquities in the Capitoline Museums, the Royal Ontario Museum, and the Acropolis Museum(2024-12)Through three case studies, this research project examines sample groups of classical antiquities in modern museums: their collection in conjunction with the formation of the museum, their display and valuation as part of an inherent narrative, and their interpretation as artistic or archaeological objects. The case studies evaluate classical antiquities from the collections of the Capitoline Museums of Rome, Italy, the Royal Ontario Museum of Toronto, Canada, and the Acropolis Museums of Athens, Greece. The antiquities provide insight into the development and function of each museum, as well as the role of classical antiquities within the formation of national identities for the three modern museums and countries, which is demonstrated in the way that each object is valued and interpreted by the museum as either art or archaeology.Item Exploring Chefs’ Behaviours and Attitudes Influence Public Awareness of Sustainable Food Practices(2024)The dominant food system is having a major impact on our planet causing extreme environmental change from greenhouse gas emissions to deforestation along with inadequate and unhealthy diets for much of the world’s population. Chefs are important actors in food systems, who have the capacity to influence consumer awareness and food choices, and thus have a role to play in helping to shift towards a more sustainable food system. However, existing research on this topic is limited. Drawing upon environment studies literature and primary research, including interviews with chefs working in restaurants and culinary teaching institutions in the Kingston, Ontario area. This study explores how chefs’ behaviors and attitudes can influence sustainable food practices. This study expands on initial research on this topic by providing a community-based research project focused on Eastern Ontario. My findings demonstrate that chefs have the knowledge and skills to make decisions that can impact consumer's choices and practices. Chefs' emotional and symbolic relationships towards food drive their sustainability motives, as this creates community and meaning behind what they do. Thus, when chefs have access to resources on sustainability (environmental, social, and economic impacts of food) and sustainable food practices and techniques, they can be motivated and inspired to contribute to food system change. However, current policies shaping who produces food, how food is produced, and how food waste is managed limit chefs’ abilities to change processes and practices within the food system.Item Studying the Irradiation Effect on the Thermal Creep Properties of Zircalloy-2 via Indentation Creep Test Method(2024-12-09)This dissertation studied the irradiation effect on the thermal creep properties of reactor-used Zirconium alloy via proton irradiation and indentation creep test method. The general introduction in Chapter 1 discussed the background and motivation as well as the planned works of this dissertation. Chapter 2 presents the literature review related to this study. In Chapter 3, we explored the method to determine the creep parameters based on indentation creep test results, in order to understand the creep deformation mechanisms. An iterative FEM simulation method was performed to get the best fit of the experimental indentation creep test data. A strain hardening creep model is developed to predict the low temperature creep behaviour of Zircaloy-2. The creep mechanism of Zircaloy-2 and irradiation effect is discussed according to the creep parameters including stress exponent (n), activation volume (V*) and activation energy (Q) that calculated based on indentation creep data. To better understand the indentation creep mechanism and irradiation effect, in Chapter 4, TEM through-thickness lift-outs were made using FIB under the indents to characterize the deformation microstructure of the plastic zone. The temperature and irradiation effect on the creep mechanism are then discussed. In Chapter 5, the source mechanism of c+a dislocation was studied by examining the deformation microstructure at the edge of the plastic zone. Chapter 6 is the general conclusion of this dissertation. At temperature below 200 °C, dislocation glide by overcoming Peierls stress could be the predominant creep mechanism. The plastic zone expands gradually by gliding of dislocations into the undeformed area. At temperatures above 200 °C, annihilation of dislocation by pipe diffusion-controlled dislocation climbing could be the dominant creep mechanism. Irradiation induced loops impede the gliding of a-type dislocations and annihilation of dislocations, higher activation energy is required for the creep deformation of irradiated sample. Larger plastic zones are required for deformation of irradiated samples due to the localized deformation behavior. Small loops form at the edge of plastic zone, dislocation nucleation could be the creep mechanism under low stress. dislocations are proved can nucleate inside the grain in the absence of a-type dislocation activity.Item Investigating the Distribution of Peatland Permafrost and Its Sensitivity to Climate and Ecosystem Change in Coastal Labrador, Northeastern Canada(2024-12-09)Northern peatlands cover nearly 4 million km2, and roughly half of these contain periglacial landforms (palsas, peat plateaus). Recent estimates report that palsas and peat plateaus are more abundant in continental than coastal locations in northeastern Canada. However, use of coastal permafrost peatlands by Labrador Inuit and Innu for traditional activities suggests an abundance of palsas and peat plateaus along the Labrador Sea coastline. This thesis investigates the current distribution and thermal state, past sensitivity, and future resilience of peatland permafrost in coastal Labrador using field, remote sensing, and thermal modelling investigations. A permafrost peatland inventory was developed through a multi-mapper consensus-based process, supported by extensive field validations. Permafrost peatlands were found in lowland locations within 22 km of the coastline. While palsas were spread along the coastline, peat plateaus were concentrated between 53 and 55°N, where post-glacial marine invasions had occurred. The thermal state of four palsas in southeastern Labrador was then evaluated using records from shallow boreholes (<5.7 m). These palsas were characterized by low initial ground temperatures but experienced warming and subsidence throughout the study period (2015-2022). The greatest thaw occurred following the exceptionally warm winter of 2020-2021. Long-term changes in peatland permafrost were explored using aerial photography and satellite imagery of seven peatlands (1948-2021). Changes in landform extents were noted, though peat plateaus were found to thaw at lower rates than palsas. Widespread degradation was linked to regional warming and local greening. Finally, thermal modelling simulations calibrated to borehole records from nine peatlands were generated in the Northern Ecosystem Soil Temperature model. Permafrost was projected to disappear at all sites by 2100 under both climate and/or ecosystem change scenarios, and landforms were found to be more sensitive to ecosystem change than to climate warming alone. This thesis significantly advances our knowledge on peatland permafrost in coastal Labrador. Permafrost was more widespread than expected, though much of it is undergoing thaw and subsidence in response to climate warming and ecosystem change. The sensitivity of palsas and peat plateaus to ecosystem change necessitates the development of local ecosystem-based adaptation strategies for peatland permafrost in coastal Labrador.Item Divided We Fall: Cohesion and Fragmentation in Excluded Minority Movements(2024-12-09)Ethnic minorities face a-priori incentives to form cohesive political movements when confronting structurally advantaged majorities in ethnic states. In spite of these incentives, scholarship has consistently shown organizational fragmentation to be the norm. Why? Why are ethnopolitical minority movements organizationally fragmented in some cases, and cohesive in others? What is the impact of ethnic exclusion on minority movements’ cohesiveness? This dissertation argues that ethnic minority leaders’ perceptions of opportunity and threat shape their movements’ internal organizational patterns and strategies. It illustrates a variety of ways in which the attribution of opportunity and threat informs leaders’ strategic choices, facilitates and constrains inter-ethnic coalition-building, and ultimately, shapes the patterns of cohesion and fragmentation within ethnopolitical minority movements. Overall, this project argues that movements are most likely to fragment when their leaders perceive the environment as either extraordinarily open or closed; environments which are perceived as moderately challenging are associated with organizational cohesion. Ideological and strategic differences serve as intermediary variables: political actors face incentives to reconsider their broad strategies in extraordinarily challenging, closed political environments (causing fragmentation), set aside internal strategic and ideological differences in moderately challenging environments (leading to increased unity), and differentiate along ideological lines in exceptionally open political environments (causing fragmentation). Each of this dissertation’s three articles adds a component to this overall theory. The first article traces changes in Palestinian leaders’ perceptions of opportunity and threat within Israel since 2015. The second compares and contrasts the strategic choices of Palestinian and Kurdish leaders within Israel and Turkey (respectively) over longer timespans, since these states’ establishment. The third makes the case that Palestinian and Jewish activists are integrated into a broader, binational, counter-hegemonic movement within Israel, resisting the state’s ethnic-hierarchical order. This project primarily relies on data from 35 semi-structured interviews with 36 Palestinian and Jewish politicians and activists, conducted between 2017-2023, as well as extensive media and archival research. The argument is established through primarily qualitative methods, including process tracing, discursive content analysis, and diachronic comparative analysis in the Israeli case, supplemented by synchronic analysis using additional evidence from Turkey.
