Border Brides From Southeast Asia To China : Is The Hidden Trafficking Crime Being Rationalized, Xi Chen
Chulalongkorn University Theses and Dissertations (Chula ETD)
Along the border between China and the Peninsula of Southeast Asia, Myanmar, Laos and Vietnam are the three countries most closely linked to China, not only for geopolitical relations, but also for the similarities between different economies, societies and ethnic cultures. With the wave of globalization comes a huge number of economic opportunities and the mobility of people from other countries and ethnicities to pursue economic benefits first and foremost. There are limited opportunities for legitimate and recognized jobs through official procedures, especially in a country where the demographic dividend is a major advantage, and where human capital is not …

Curatorial Practice Project For Art Exhibition: “Where Are We Landing”, Phiraya Ardwichai
Chulalongkorn University Theses and Dissertations (Chula ETD)
Over the past several decades, exhibitions concerning Southeast Asia have tended to operate within a geopolitical framework that emphasizes historical narratives shaped by colonial processes. Within this curatorial paradigm, the human subject is often positioned at the center of meaning-making and perception, reinforcing the dominance of the nation-state as the primary unit of power. At the same time, such frameworks tend to marginalize ecological concerns, particularly the complex interrelations between humans and more-than-human entities. This research critically examines prevailing curatorial practices within this context, investigates the impact of green imperialism in the region, and proposes an alternative curatorial approach through …

The surveillance of migratory waterbirds (MWs) for avian influenza virus (AIV) is indispensable for the early detection of a potential AIV incursion into poultry. Surveying AIV infections and virus subtypes in understudied MW species could elucidate their role in AIV ecology. Oropharyngeal–cloacal (OPC) swabs were collected from non-mallard MWs between 2006 and 2011. OPC swabs (n = 1,158) that molecularly tested positive for AIV (Cts ≤ 32) but tested negative for H5 and H7 subtypes were selected for virus isolation (VI). The selected samples evenly represented birds from all four North American flyways (Pacific, Central, Mississippi, and Atlantic). Eighty-seven …

Rapid advancements in technology often yield research inquiry into novel applications and drone (i.e., unoccupied aircraft systems or UAS) applications in wildlife management are no exception. We questioned the time lag between drone‐related research and end‐user assessments. We implemented an online, cross‐sectional survey of wildlife professionals to better understand current drone use and benefits or concerns, complemented by a review of contemporary peer‐reviewed and gray literature. We found little disparity between scientific inquiry and end‐user experiences (i.e., similar trends among concerns in published literature and survey results). Exploring new (i.e., advancements in computer vision) and refining original drone applications (i.e., …

Understanding the epidemiology and transmission dynamics of transboundary animal diseases (TADs) among wild pigs (Sus scrofa) will aid in preventing the introduction or containment of TADs among wild populations. Given the challenges associated with studying TADs in free-ranging populations, a surrogate pathogen system may predict how pathogens may circulate and be maintained within wild free-ranging swine populations, how they may spill over into domestic populations, and how management actions may impact transmission. We assessed the suitability of Torque teno sus virus 1 (TTSuV1) to serve as a surrogate pathogen for molecular epidemiological studies in wild pigs by investigating …

Bayesian Integrated Species Distribution Models For Hierarchical Resource Selection By A Soaring Bird, Ryo Ogawa, Guiming Wang, L. Wes Burger, Bronson Strickland, J. Brian Davis, Fred L. Cunningham
United States Department of Agriculture Wildlife Services: Staff Publications
Migratory birds exhibit seasonal geographic range (hereafter, range) dynamics during the annual cycle. Few studies have examined how migratory birds select their habitats for range occupancy at the species level and space use at the individual level simultaneously. We hypothesized that environmental variables directly related to fitness components would affect the range occupancy probabilities of migrants, whereas environment variables related to movements and flights would affect the space use intensities of migrants. We built Bayesian integrated species distribution models (ISDMs) to evaluate the effects of climate conditions, wind conditions, and landcover compositions on the seasonal range dynamics of American white …

Understanding The Dynamics Of Food And Economic Development In The Community Of Kakisa, Northwest Territories, Canada, Laura Rodriguez Reyes
Theses and Dissertations (Comprehensive)
For Indigenous Peoples, the land embodies a source of cultural and spiritual well-being that is linked to their way of life and identities through divine and traditional connections. Unfortunately, colonial powers, the global food system, socioeconomic inequalities and environmental degradation are impacting northern Indigenous lands and food systems, leading to food insecurity. Nevertheless, communities are still thriving in the face of adversity. In the Northwest Territories, on the lands of Ka’a’gee Tu First Nations (KTFN) in the community settlement of Kakisa, people are growing food through vegetable gardens and greenhouses to support their vision of a resilient food system.

Investigating The Mobility Of Arsenic In Subarctic Mining Pollution-Affected Peatlands Near Yellowknife, Northwest Territories, Jeremy Leathers
Theses and Dissertations (Comprehensive)
Arsenic (As) is a pollutant of global concern that is detrimental to human and environmental health. Between 1948 and 2004, mining operations near Yellowknife, NT released over 20,000 tonnes of As trioxide (As2O3) that continues to persist in the surrounding landscape. Although much effort has been put into studying the chemical forms, spatial distribution, ecological impacts, and environmental cycling of As in the area, more work is needed to determine the controls of As mobility between the terrestrial and aquatic components of the landscape. Soils are known reservoirs of legacy As that can release it downslope …

This dissertation argues that visual artists who live and work on the Saugeen (Bruce) Peninsula, in Ontario, Canada, are co-creating artworks with non-humans, which is evidence of more-than-human world-making. Such co-creative experiences are the result of, and catalysts for the kinds of enchantment our human worlds need to form meaningful and holistic connections with non-humans, effectively creating a more inclusive pluriverse. After reviewing interdisciplinary literature in posthuman studies, creative geography, arts-based practices, environmental humanities, Indigenous knowledges, and political ontology, I designed my research to include a combination of qualitative methodologies and methods, including autoethnography and research-creation, to investigate fourteen visual …
Indigenous Wholistic Abolition: Visioning Indigenous Queer, Two-Spirit & Indigiqueer Futures, Giselle Dias
Indigenous Wholistic Abolition: Visioning Indigenous Queer, Two-Spirit & Indigiqueer Futures, Giselle Dias
Theses and Dissertations (Comprehensive)
As a queer Métis, activist and organizer in the field of prisoners’ rights, penal abolition, and transformative justice, I have been interested in learning about how Indigenous peoples’ relationship with Aki (Land) grounds abolition theory and guides the ways that I and other Indigenous abolitionists engage in abolition. As part of this process, I wanted to speak to other Indigenous queer, Two-Spirit, trans, non-binary, and/or Indigiqueer (Q2STNBI) people about their visions of abolition and abolitionist futures through a relational Land-based lens. Therefore, I used a methodology that centres Métis worldviews and community organizing and is grounded in the ethics of …

Understanding Health And Well-Being Outcomes Associated With Protected Coastal Ecosystems: A Fundy National Park Case Study., Mhairi K. Chandler
Theses and Dissertations (Comprehensive)
The COVID-19 pandemic has significantly impacted the mental health and well-being of Canadians, prompting many to turn to nature for consolation and social interaction. However, there is a lack of evidence linking these outcomes specifically to coastal areas. To address this gap, we conducted a self-reported survey at Fundy National Park, New Brunswick, Canada, in summer 2022. Over 400 visitors participated, revealing nature enjoyment, physical health, and mental well-being as primary motivators for park visitation. Notably, mental well-being showed significant differences across gender, sexual identity, and ethnicity, with males, straight individuals, and others exhibiting distinct preferences compared to females, 2SLGBTQIA+ …
Integrating Biodiversity Protection And Climate Mitigation In Nature-Based Climate Solutions: An Indicator Analysis, Tatyana Feiner
Integrating Biodiversity Protection And Climate Mitigation In Nature-Based Climate Solutions: An Indicator Analysis, Tatyana Feiner
Theses and Dissertations (Comprehensive)
Climate change and biodiversity loss have been recognized as complex, interconnected issues that require synergistic and mutually reinforcing policy solutions. Given the ambitious commitments by the Canadian government to abate the two “wicked problems”, this study investigates whether the government has constructed a policy framework that synthesizes climate and biodiversity concerns through policy integration and mainstreaming processes. Through a semi-systematic and comprehensive content analysis approach, this study assesses the degree to which biodiversity protection and climate mitigation have been effectively mainstreamed into federal policies, programs, and instruments. Specifically, the study constructs an evaluative framework based on established “best practices” of …
Assessing Road Dust Impacts On Macroinvertebrates Community Structure In Canadian Arctic Lakes, Hong Yi Gao
Assessing Road Dust Impacts On Macroinvertebrates Community Structure In Canadian Arctic Lakes, Hong Yi Gao
Theses and Dissertations (Comprehensive)
In the Canadian Arctic, unpaved gravel roads are essential for regional accessibility but are also potential sources of road dust runoff. My study investigated the impacts of road dust from the Dempster and Inuvik-Tuktoyaktuk Highways on adjacent freshwater ecosystems, focusing on water quality parameters and macroinvertebrate communities. Using a stratified random sampling design, 18 lakes were studied across two regions (boreal forest and tundra) and three distance categories from the road (0-300 m, 300-600 m, and > 600 m). Contrary to my initial hypotheses, findings revealed no significant differences in water quality or invertebrate communities relative to distance from the road. …
Road Extraction On Remote Sensing Imagery: Historical Mapping Of The Brazilian Amazon, Jonas Paiva Botelho Jr
Road Extraction On Remote Sensing Imagery: Historical Mapping Of The Brazilian Amazon, Jonas Paiva Botelho Jr
Graduate Theses/Dissertations
This work proposes an artificial intelligence model based on U-Net architecture to map road networks in the Brazilian Amazon. Over the years, the Amazon region has been heavily exploited, leading to increased deforestation rates, contributing to CO2 emissions, amplifying global warming, and causing a disturbance in local fauna and flora. The expansion into the forest by illegal miners, loggers, and land grabbers can be tracked down by the construction of roads, which we can refer to as the arteries of deforestation. Previous works on the matter proposed algorithms that use high-resolution imagery to map roads precisely. However, this work approach …
