Exploring The Relationship Between Gender, Race, And Space, And Toronto Community Housing Policy, Anita Rachel Ewan

Theses and Dissertations (Comprehensive)

This dissertation presents the racial-gendered lived experiences of Black women living in Toronto Community Housing (TCH; subsidized housing). This research found that Black women and their families are disproportionately faced with challenges due to barriers caused by housing policy and procedures that also affect the overall development and wellbeing of their children. It also highlights the ways in which Black women continue to thrive and survive in the face of detrimental and derelict living conditions; accomplished through community development and support initiatives, and fostering strong communities.

This is a qualitative research project that includes an art-based method. Utilizing a feminist …

The Influence Of Landforms And Sampling Approaches On Riparian Buffer Area And Complexity, Houjun Ding

Dissertations, Master's Theses and Master's Reports

A riparian area is a zone of interaction between aquatic and terrestrial ecosystems. Delineating accurate riparian management zones (RMZs), often utilized in Best Management Practices (BMPs) for wetlands and stream protection, is important. The Riparian Buffer Delineation Model (RBDM) has been used extensively for accurate RMZs delineation. Utilizing the validated RBDM generates additional questions about riparian area form and function, which will ideally lead to an improved understanding of the ecological process within these zones. This study aims to determine how geomorphic landforms and their associated landscape characteristics influence riparian areas in terms of shape and complexity, whether sampling methods …

The Impacts Of Accessibility On Vulnerability Of Place In Comfort Castle, Jamaica, Heather Thole

Dissertations, Master's Theses and Master's Reports

Jamaica experiences meteorological, hydrological, and geological natural hazards that can produce island-wide impacts. The island’s exposure to multiple hazard types requires effective and sustainable mitigation and disaster risk management to lessen potential impacts, especially for vulnerable populations and communities. Comfort Castle, a small rural farming community, sits in the upper Rio Grande Valley of Portland parish and experiences earthquakes, landslides, hurricanes, heavy rainfall, and floods. Steep terrain and remoteness due to geographic location affect the community’s geophysical vulnerability. Their social vulnerability results from a lack of employment, health, educational, and livelihood resources within the community. Together, geophysical, and social factors …

Innovative Approaches To 3d Gis Modeling For Volumetric And Geoprocessing Applications In Subsurface Infrastructures In A Virtual Immersive Environment, Pragya Srivastava

Graduate Theses, Dissertations, and Problem Reports (ETD)

As subsurface features remain largely ‘out of sight, out of mind’, this has led to challenges when dealing with underground space and infrastructures and especially so for those working in GIS. Since subsurface infrastructure plays a major role in supporting the needs of modern society, groups such as city planners and utility companies and decision makers are looking for an ‘holistic’ approach where the sustainable use of underground space is as important as above ground space. For such planning and management, it is crucial to examine subsurface data in a form that is amenable to 3D mapping and that can …

Gendered Access To Wetland Gardens (Dimba) In Northern Malawi, Rhoda Nyirenda

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to increasing degradation of upland fields and in the face of erratic rains and increasing occurrence of droughts and floods and increasing food prices, smallholder farmers in many places across sub Saharan Africa engage in wetland cultivation for livelihoods security (Mutambikwa et al., 2000). A cultivatable wetland area is considered prime land, and a desired opportunity that every rural family need for the purpose of food production. Studies have indicated that wetland cultivation significantly contributes to household’s income and food security. Wetland agriculture, however, in Malawi and most of the sub-Saharan African countries is marred with issues of access …

Resilience In The Mountains: Exploring The Labor And Motives Of Food-Caregiver Women Repairing Broken Food Systems In West Virginia Communities, Heidi Lynn Gum

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over the past four years the Food Justice Lab, now housed within the Center for Resilient Communities at West Virginia University, hosted a series of food access planning workshops across the state of West Virginia. Mobilizing more than 200 participants, the Nourishing Networks workshop training program was designed to build grassroots capacity for food system change. Eighty-percent of workshop participants were women and dialogues recorded at these events revealed how women are disproportionately impacted by food insecurity and disproportionately labor to repair a broken food system. Women in West Virginia are not only growing food, feeding their families, selling it …

"We Have Ground To Cover For Each Other": A Case Study Of Mentoring Across Black Sorority Alumni In North Central West Virginia, Elizabeth C. Dever

Graduate Theses, Dissertations, and Problem Reports (ETD)

Black sororities are much more than their stereotypes of stepping and partying. They are service organizations that have a deep impact on their communities and help shape the identities of their members. These organizations can be seen at Historically Black Colleges and Universities (HBCUs) and Predominately White Institutions (PWIs). Black sororities are different than their traditionally white counterparts because the majority of active time in membership occurs after graduation. This thesis utilizes a case study of Black sororities in North Central West Virginia and West Virginia University. In spaces lacking in diversity and inclusion, Black sororities can serve as a …

Dropsonde Observations Of The Ageostrophy Within The Pre-Cold-Frontal Low-Level Jet Associated With Atmospheric Rivers, Rueben Demirdgian, Joel R. Norris, Andrew Martin, F. Martin Ralph

Geography Faculty Publications and Presentations

The pre-cold-frontal low-level jet (LLJ) is an important contributor for water vapor transport within atmospheric rivers, though its dynamics are not completely understood. The present study investigates the LLJ using dropsonde observations from 24 cross-atmospheric river transects taken during the CalWater-2014, 2015 and the AR-Recon 2016, 2018 field campaigns. It is found that the LLJ, located at ;1-km elevation ahead of the cold front, has an average maximum wind speed of 30ms21 and is strongly supergeostrophic with an average ageostrophic component of 6ms21. The alongfront ageostrophy occurs within the atmospheric layer (750–1250 m) known to strongly control orographic precipitation associated …

A Digital Archive Of Human Activity In The Mcmurdo Dry Valleys, Antarctica, Adrian Howkins, Stephen M. Chignell, Poppie Gullett, Andrew G. Fountain, Melissa Carrie Brett, Evelin Preciado

Geography Faculty Publications and Presentations

Over the last half century, the McMurdo Dry Valleys (MDV) of East Antarctica have become a globally important site for scientific research and environmental monitoring. Historical data can make important contributions to current research activities and environmental management in Antarctica but tend to be widely scattered and difficult to access. We address this need in the MDV by compiling over 5000 historical photographs, sketches, maps, oral interviews, publications, and other archival resources into an online digital archive. The data have been digitized and georeferenced using a standardized metadata structure, which enables intuitive searches and data discovery via an online interface. …

Socio-Hydrology: An Interplay Of Design And Self-Organization In A Multilevel World, David J. Yu, Heejun Chang, Taylor T. Davis, Vicken Hillis, Landon T. Marston, Woi Sok Oh, Murugesu Sivapalan, Timothy M. Waring

Geography Faculty Publications and Presentations

The emerging field of socio-hydrology is a special case of social-ecological systems research that focuses on coupled human-water systems, exploring how the hydrologic cycle and human cultural traits coevolve and how such coevolutions lead to phenomena of relevance to water security and sustainability. As such, most problems tackled by socio-hydrology involve some aspects of engineering design, such as large-scale water infrastructure, and self-organization in a broad context, such as cultural change at the population level and the hydrologic shift at the river basin or aquifer level. However, within the field of socio-hydrology, it has been difficult to find general theories …

Coal Mining Sector Contribution To Environmental Conditions And Human Development Index In East Kalimantan Province, Kunny Izza Indah Afkarina, Sindhung Wardana, Poerborini Damayanti

Journal of Environmental Science and Sustainable Development

Coal mining has been one of the issues that led to pros and cons in Indonesia. Research shows that mining activities are one of the factors that affect people’s incomes and local and national economic development. However, mining is a lucrative activity that leads to construction booms that attract population growth and lead to deforestation, thus affecting the environmental conditions of a region. The coal mining industry of Indonesian province of East Kalimantan, on the island of Borneo, provides most of the economic base needed to build the infrastructure and provide energy of the country. Kalimantan Province accounts for approximately …

Recent Disruptions In The Timing And Intensity Of Precipitation In Calakmul, Mexico, Sofia Mardero, Birgit Schmook, Zachary Christman, Sarah E. Metcalfe, Betsabé De La Barreda-Bautista

School of Earth & Environment Departmental Research

This study addresses changes in the timing and intensity of precipitation from 1982 to 2016 from three meteorological stations around Calakmul, Mexico, a landscape balancing biodiversity conservation and smallholder agricultural production. Five methods were used to assess changes in precipitation: the Mann-Kendall test of annual and wet season trends; a fuzzy-logic approach to determine the onset of the rainy season; the Gini Index and Precipitation Concentration Index (PCI) to evaluate the temporal distribution of precipitation; Simple Precipitation Intensity Index (SDII) to evaluate precipitation intensity; and the Rainfall Anomaly Index (RAI) to identify the deficit or surplus of rainfall compared with …

Agronomic Or Contentious Land Change? A Longitudinal Analysis From The Eastern Brazilian Amazon, Stephen Aldrich, Cynthia S. Simmons, Eugenio Arima, Robert T. Walker, Fernando Michelotti, Edna Castro

Department of Earth and Environmental Systems

Since 1984, nearly 1,000 people have been killed in the Brazilian Amazon due to land conflicts stemming from unequal distribution of land, land tenure insecurity, and lawlessness. During this same period, the region experienced almost complete deforestation (< 8% forest cover by 2010). Land conflict exacts a human toll, but it also affects agents’ decisions about land use, the subject of this article. Using a property-level panel dataset covering the period of redemocratization in Brazil (1984) until the privatization of long-term leases in the eastern Amazon (2010), we show that deforestation is affected by land conflict, particularly in cases of expropriation of property for agrarian reform settlement formation. Deforestation on these settlements is much greater when soils are poor for agriculture and when the land has been the object of past conflict. Deforestation and conflict are episodic, and both agronomic drivers and contentious drivers of land change are active in the region. Ultimately, the outcome of these processes of contentious and agronomic land change is substantial deforestation, regardless of who was in possession and control of the land.

There Must Be Something In The Water: Understanding Pfas Contamination Of Groundwater As A National Security Issue, Kylie N. Ford

Student Theses 2015-Present

This report addresses the widespread pollution of domestic groundwater resources with Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) caused by firefighting activities performed at military installations across the United States. Two former military bases in Southeastern Pennsylvania are used as a single case study: the Naval Air Development Center (NADC) in Warminster and the Naval Air Station Joint Reserve Base (NASJRB) in Horsham. Chapter 1 gives a history of domestic military bases from the perspective of the infrastructure buildup and downsizing that occurred over the 20th Century, along with the environmental degradation revealed during brownfield redevelopment. The chapter then gives specifics about …

Direct And Indirect Effects Of Temperature And Prey Abundance On Bald Eagle Reproductive Dynamics, Joshua H. Schmidt, Judy Putera, Tammy L. Wilson

United States National Park Service: Publications

Understanding the mechanisms by which populations are regulated is critical for predicting the effects of large-scale perturbations. While discrete mortality events provide clear evidence of direct impacts, indirect pathways are more difficult to assess but may play important roles in population and ecosystem dynamics. Here, we use multi-state occupancy models to analyze a long-term dataset on nesting bald eagles in south-central Alaska with the goal of identifying both direct and indirect mechanisms influencing reproductive output in this apex predator. We found that the probabilities of both nest occupancy and success were higher in the portion of the study area where …

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

This paper illustrates the issue of food deserts faced by urban areas in three parts. Part one focuses on defining food deserts and what exactly the term denotes as well as who is affected by their present existence socially, physically, and economically. Part two presents research on some of the current policies and programs in place to address the issue of food deserts and discusses a few of the difficulties in implementing them. These approaches are then further analyzed for effectiveness in varying regions. Part three explores a handful of alternative methods to combat this urban issue in order to …

A Feasibility Study On The Application Of Tvdi On Accessing Wildfire Danger In The Korean Peninsula, Kwang Nyun Kim, Seung Hee Kim, Myoung Soo Won, Keun Chang Jang, Won Jun Choi, Yun Gon Lee

Mathematics, Physics, and Computer Science Faculty Articles and Research

Wildfire is a major natural disaster affecting socioeconomics and ecology. Remote sensing data have been widely used to estimate the wildfire danger with an advantage of higher spatial resolution. Among the several wildfire related indices using remote sensing data, Temperature Vegetation Dryness Index (TVDI) assesses wildfire danger based on both Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST). Although TVDI has physical advantages by considering both weather and vegetation condition, previous studies have shown TVDI does not performed well compare to other wildfire related indices over the Korean Peninsula. In this study we have attempted multiple modification to …

Grandes Interrogações Sobre O Futuro Dos Povos Indígenas Isolados, Conselho Indigenista Missionário

Tipití: Journal of the Society for the Anthropology of Lowland South America

O presente artigo, de autoria coletiva da equipe do Conselho Indigenista Missionário (Cimi), pretende traçar um quadro geral da situação de vulnerabilidade dos povos indígenas em isolamento e contato inicial no Brasil, tendo como referência temporal o ano de 2016. É preocupante o avanço da exploração dos recursos naturais em territórios ocupados por esses povos, principalmente com a mineração e a exploração de madeira, seja dentro de terras indígenas destinadas aos povos em isolamento, em terras indígenas partilhadas por outros povos, ou em territórios onde a proteção ou o reconhecimento pelo Estado não se faz presente.
