New Approach For Temporal Stability Evaluation Of Pseudo-Invariant Calibration Sites (Pics), Fatima Tuz Zafrin Tuli

Electronic Theses and Dissertations

Pseudo-Invariant Calibration Sites (PICS) are one of the most popular methods for in-flight vicarious radiometric calibration of Earth remote sensing satellites. The fundamental question of PICS temporal stability has not been adequately addressed. However, the main purpose of this work is to evaluate the temporal stability of a few PICS using a new approach. The analysis was performed over six PICS (Libya 1, Libya 4, Niger 1, Niger 2, Egypt 1 and Sudan 1). The concept of a “Virtual Constellation” was developed to provide greater temporal coverage and also to overcome the dependence limitation of any specific characteristic derived from …

Empirical Absolute Calibration Model For Multiple Pseudo-Invariant Calibration Sites, Bipin Raut

Electronic Theses and Dissertations

This work extends an empirical absolute calibration model initially developed for the Libya 4 Pseudo-Invariant Calibration Site (PICS) to five additional Saharan Desert PICS (Egypt 1, Libya 1, Niger 1, Niger 2, and Sudan 1), and demonstrates the efficacy of the resulting models at predicting sensor top-of-atmosphere (TOA) reflectance. It attempts to generate absolute calibration models for these PICS that have an accuracy and precision comparable to or better than the current Libya 4 model, with the intent of providing additional opportunities for sensor calibration. In addition, this work attempts to validate the general applicability of the model to other …

Evaluation Of An Extended Pics (Epics) For Calibration And Stability Monitoring Of Optical Satellite Sensors, Md Nahid Hasan

Electronic Theses and Dissertations

Pseudo Invariant Calibration Sites (PICS) have been increasingly used as an independent data source for on-orbit radiometric calibration and stability monitoring of optical satellite sensors. Generally, this would be a small region of land that is extremely stable in time and space, predominantly found in North Africa. Use of these small regions, referred to as traditional PICS, can be limited by: i) the spatial extent of an individual Region of Interest (ROI) and/or site; ii) and the frequency of how often the site can be acquired, based on orbital patterns and cloud cover at the site, both impacting the time …

Do You Believe In Ghost Apartments?, Michael Lewyn

Scholarly Works

According to the popular press, expensive cities are being overrun by "ghost apartments"- condominiums owned by wealthy foreigners, but used as investments rather than being rented out to local residents. This article points out that such apartments are in fact a very small percentage of housing supply, even in some cities that are supposedly overran with such condos. More importantly, the existence of new “ghost apartments” does not justify exclusionary zoning policies. If a city popular with foreign investors discourages construction of new housing, investors are likely to purchase older housing units, outbidding local residents for those units. In this …

Maroon Colonies And New Orleans Neutral Grounds: From A Protosuburban Past To A Postsuburban Future, Lynnell L. Thomas

American Studies Faculty Publication Series

This essay examines New Orleans maroon colonies as a precursor to the postsuburban constellations that shape the contemporary urban landscape. These communities served as the original neutral grounds where Africans, Afro-Creoles, and Native Americans created spaces beyond the purview of slave owners and government authorities. These protosuburban enclaves anticipated the vibrancy and prolificacy of the “global urban periphery” that Roger Keil describes in his research. They also inform twentieth- and twenty-first-century efforts by black New Orleanians to carve out their own urban neutral grounds: spaces resistant to the hegemonic forces of neoliberalism and neo-Bourbonism, as manifested in the traditions of …

Cliff-Top Dunes In The Lower Chippewa River Valley Of West-Central Wisconsin, Jason Millett

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose of this Master’s thesis is to investigate recently identified cliff-top sand dunes located within the Lower Chippewa River Valley (LCRV), Wisconsin, USA. Research within the LCRV notes the existence of a variety of aeolian deposits, but a comprehensive explanation of their complete spatial distribution, genesis, age, and paleoenvironmental significance does not exist. In particular, stabilized cliff-top dunes with a parabolic form remain poorly understood. This problem is exacerbated by a lack of clarity in the literature regarding the genesis of dunes in a cliff-top position. Therefore, this thesis begins by reviewing the literature concerning sand dunes in cliff-top …

Open Secrets, Congressional Oversight, And The Geopolitics Of The Cia Drone Program, Marita C. Murphy

Theses and Dissertations--Geography

Analyzing four congressional hearings that publicly discuss the CIA’s ‘secret’ drone program, this thesis considers the interaction between publicity and secrecy in facilitating practices of later-modern warfare. Specifically, I examine the content of these drone hearings within the broader context of leaks, Obama administration speeches, and public interest in CIA drones to better understand how open secrecy engages with public oversight. I argue these hearings are deceptively productive. While they largely fail as oversight events, the hearings facilitate numerous unexpected outcomes—including the normalization and entrenchment of the CIA drone program. Paradoxically then, publicity proves essential to the maintenance and acceptance …

Visualizing Barrier Dune Topographic State Space And Inference Of Resilience Properties, Li-Chih Hsu

Theses and Dissertations--Geography

The linkage between barrier island morphologies and dune topographies, vegetation, and biogeomorphic feedbacks, has been examined. The two-fold stability domain (i.e., overwash-resisting and overwash-reinforcing stability domains) model from case studies in a couple of islands along the Georgia Bight and Virginia coast has been proposed to examine the resilience properties in the barrier dune systems. Thus, there is a need to examine geographic variations in the dune topography among and within islands. Meanwhile, previous studies just analyzed and compared dune topographies based on transect-based point elevations or dune crest elevations; therefore, it is necessary to further examine dune topography in …

The Geography Of Crime: Placing Geographers In The Space Of Criminologists, Anthony Wv Piscitelli

Theses and Dissertations (Comprehensive)

The Geography of Crime consists of five articles. The first article, Exploring opportunities for geographers to explain the spatial distribution of crime, serves as a key conceptual link between each of the other four articles. This paper provides a broad introduction to the dissertation showing what gaps in the crime literature exist, especially those ripe for analysis by geographers. Three primary directions emerged as a focus of this dissertation: overarching theoretical contributions, specialized geographic quantitative techniques, and qualitative approaches centred on the concept of place.

The second article, Connecting social disorganization theory to broken windows and routine activities proposes …

Border Disorder: 'Irregular Bangladeshis', Xenophobia And Crimmigration Control In India, Sujata Ramachandran

Theses and Dissertations (Comprehensive)

In India, the crisis of migration tied to the entry, presence and assimilation of the so-called ‘irregular’, ‘illegal Bangladeshi migrants’ is now an undisputed reality, seemingly affecting all geographical areas located within the national territories in multiple adverse ways. A decidedly strident xenophobic rhetoric attaches the presence of such migrants in an indiscriminate fashion to unending anxieties and urgent problems, whilst constantly drawing attention to the inefficacies of immigration enforcement and deficiencies of (interior and exterior) borders controls. This dissertation addresses key moments in the making and deepening of this national crisis and its management by state authorities over the …

Refugees From Syria Caught Between War And Borders: A Journey Towards Protection, Maissaa Almustafa

Theses and Dissertations (Comprehensive)

This dissertation examines the global crisis of protection through the lens of the Syrian refugee crisis and the particular experiences of refugees’ journeys to Sweden.

In doing so, the dissertation challenges the dominant narratives that represent refugees either as victims who deserve aid in their regions, or as threats when they exert their agency and journey towards the global north. In the same vein, the dissertation problematizes the dominant narrative of the “European crisis of migration” and proposes that the “unauthorized” arrivals of refugees in Europe are reflections of a global crisis of protection, a crisis that develops as a …

Policy, Plans And Processes For Developing And Improving The Use Of Hazard Maps In Climate Change Adaptation For Yukon Communities, Stephanie Pike

Theses and Dissertations (Comprehensive)

Climate change has quickly become one of the most commonly discussed topics in northern Canada. Communities located in Canada’s north are facing impacts to every aspect of life. Hazard mapping is one of the tools used to predict risk from climate change impacts and thus assist communities in adaptation planning. The Northern Climate ExChange in Yukon has developed hazard maps for seven communities across Yukon. While hazard maps are a useful tool, in order for them to reach their maximum potential, users need to be well educated and trained to use them. Capacity and communication are arguably the most significant …

The Social Construction Of A Disaster Typology To Enhance Operational Emergency Planning For K-8 Public Schools In Southern Ontario, Patricia Martel

Theses and Dissertations (Comprehensive)

This dissertation outlines the development of a disaster typology that could be used as a tool for developing operational emergency plans for K-8 public schools with the potential to be applied more generally to other facilities that host vulnerable groups. The theoretical framework used to inform this study is the theory of the social construction of disasters. This theory conceptualizes disasters as being the result of the interaction between social factors, such as risk perception and vulnerability, and the hazards.The author of this dissertation is an emergency management practitioner and brought a perspective informed by both theory and practice of …

The Legitimation & Networked Unification Of #Nodapl: Diverse Discourses Of Value Validate A Collective Identity, Jacqueline Marie Ouellette

Theses and Dissertations (Comprehensive)

NoDAPL was, first and foremost, an Indigenous-led resistance against the construction of a pipeline in North Dakota. It was also a movement that built solidarity, bridging networks between international Indigenous peoples, Black Lives Matter activists, veterans, and feminists. This discourse analysis of social media and digital texts addresses the networked publics, collective identities, social capital, and intersectionality in applying Van Leeuwen’s (2007) understanding of legitimation. In doing so, the practice of reproducing and extending the values, themes, and images of various algorithmic imaginaries will be explored, as they relate to network homophily, identity construction, and mobilization. This study will argue …

Does Perceived Ecological Integrity Affect Restorative Health Outcomes? An Examination Of Visitor Experiences In Diverse Environments In An Ontario Protected Area, Catherine E. Reining

Theses and Dissertations (Comprehensive)

The human health and well-being benefits associated with nature contact is well established. Parks and other forms of protected areas contribute significantly to these benefits by providing access to nature. However, limited research has been done on how different environments within protected areas (e.g., forests, coasts, areas being restored) and the perceived quality (i.e., ecological integrity) of these environments affect the health and well-being outcomes of visitors. This study builds on previous work to better understand how visitor experiences provided by diverse natural and built environments in Pinery Provincial Park affect perceived restorative outcomes as one aspect of health and …
