Domestic Violence In Culturally And Linguistically Diverse (Cald) Communities: Perceptions, Therapeutic Approaches And Responses Of Frontline Workers In New South Wales (Nsw), Oluwatoyin A. Dedeigbo

Theses

Domestic violence is a universal public health concern (VicHealth, 2011; World Health Organisation [WHO], 2013). Domestic violence cuts across all countries, regardless of economic, social, cultural or religious differences (Ali et al., 2020; VicHealth, 2011; WHO 2013). Men are often responsible for perpetrating domestic violence against women (Australian Bureau of Statistics [ABS], 2019; Australia Institute of Health and Welfare [AIHW], 2018).

The effects of domestic violence on victims can be serious and long-term; affecting their physical and mental wellbeing, and lingering even after the exposure to violence has ended (Mitchell, 2011). That is, the effect on victims’ mental health is …

Enhanced Intensity Analysis To Quantify Categorical Change And To Identify Suspicious Land Transitions: A Case Study Of Nanchang, China, Zheyu Xie, Robert Gilmore Pontius, Jinliang Huang, Vilas Nitivattananon

Geography

Conventional methods to analyze a transition matrix do not offer in-depth signals concerning land changes. The land change community needs an effective approach to visualize both the size and intensity of land transitions while considering possible map errors. We propose a framework that integrates error analysis, intensity analysis, and difference components, and then uses the framework to analyze land change in Nanchang, the capital city of Jiangxi province, China. We used remotely sensed data for six categories at four time points: 1989, 2000, 2008, and 2016. We had a confusion matrix for only 2016, which estimated that the map of …

A Green Transition In South Africa? Sociotechnical Experimentation In The Atlantis Special Economic Zone, Richard Grant, Pádraig Carmody, James T. Murphy

Geography

South Africa faces interconnected challenges of developing and diversifying its economy and adapting to and mitigating the impacts of climate change. A green policy tilt is ascendant in the country, manifest in a cascading array of policies and special initiatives. Utilising concepts from the multi-level perspective on socio-technical transitions, we assess Africa's first designated Green Special Economic Zone (SEZ), Atlantis SEZ (ASEZ) in the Western Cape, a niche innovation aimed at transforming the Province's industrial base. This initiative is very ambitious in four respects: (1) it links green SEZ development in a deprived metropolitan area to the broader regional economy; …

Framing The Search For A Theory Of Land Use, B. L. Turner, Patrick Meyfroidt, Tobias Kuemmerle, Daniel Müller, Rinku Roy Chowdhury

Geography

Land system science and affiliated research linked to sustainability require improved understanding and theorization of land and its change as a social-ecological system (SES). The absence of a general land-use theory, anchored in the social subsystem but with explicit links to the environmental subsystem, hampers this effort. Drawing on land-use explanations, meta-analyses, and associated frameworks, we advance a broad framework structure of eight elements–aggregations of explanatory variables–with links to the biophysical subsystem, for systematic comparisons of extant explanations. Tests and models can be employed to identify which set of variables and their configurations provide robust explanations of across land uses, …

Accounting For Training Data Error In Machine Learning Applied To Earth Observations, Arthur Elmes, Hamed Alemohammad, Ryan Avery, Kelly Caylor, J. Ronald Eastman, Lewis Fishgold, Mark A. Friedl, Meha Jain, Divyani Kohli, Juan Carlos Laso Bayas, Dalton Lunga, Jessica L. Mccarty, Robert Gilmore Pontius, Andrew B. Reinmann, John Rogan, Lei Song, Hristiana Stoynova, Su Ye, Zhuang Fang Yi, Lyndon Estes

Geography

Remote sensing, or Earth Observation (EO), is increasingly used to understand Earth system dynamics and create continuous and categorical maps of biophysical properties and land cover, especially based on recent advances in machine learning (ML). ML models typically require large, spatially explicit training datasets to make accurate predictions. Training data (TD) are typically generated by digitizing polygons on high spatial-resolution imagery, by collecting in situ data, or by using pre-existing datasets. TD are often assumed to accurately represent the truth, but in practice almost always have error, stemming from (1) sample design, and (2) sample collection errors. The latter is …

Hotspot Analysis Of Unregistered Voters In Columbus, Georgia, Jordan Brasher

Columbus Community Geography Center

Dr. Jordan Brasher created this map in partnership with the New Georgia Project (NGP) during the November 2020 election cycle. NGP is a nonprofit, nonpartisan voter education, registration, and advocacy organization. Dr. Brasher used address data provided by NGP to map hotspots of densely clustered address points representing households with one or more suspected unregistered voters. Red hotspots on the map represent statistically significant spatial clusters of suspected unregistered voters; blue coldspots represent places where the address data are more spread out (i.e., a lack of spatial clustering). Notable hotspots include downtown Columbus and several areas south and east of …

Burning With Potential: Understanding The Relationship Between Biochar And Agriculture Of The Northern Glaciated Plains Ecoregion, Kaitlyn Abrahamson

Electronic Theses and Dissertations

Achieving global sustainable agriculture is one of the most incredible challenges of this century, yet many continue to try to solve this problem through the development of precision technologies. Biotechnologies, such as biochar, can perform like a precision technology while protecting agricultural land from soil erosion and fertility loss. The Northern Glaciated Plains ecoregion of the United States is little researched in the benefits from the use of biochar through improved soil nutrient capture and water retention, crop health improvements, and yield increases. The study plot has four sections of corn stover biochar and eight sections of control sections. This …

Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana

Electronic Theses and Dissertations

Human actions such as overgrazing, the development of cities at the expense of forests, high intensity and poor agricultural management, and so forth, reduce the resources available for future generations. Because Earth has limited resources, it is important to judiciously use and manage natural resources. Human actions towards nature are the focus of my research in Africa. Increased demands for grazing, agriculture, and ecosystem services led some farmers in developing countries to use unsustainable practices, which may lead to low incomes and poor food nutrition for households. Farmer managed natural regeneration (FMNR) may be a solution to these issues. FMNR …

Comparing Fence Modeling And Mapping Approaches To Support Wildlife Management And Research In Southwest Montana, Simon Albert Buzzard

Graduate Student Theses, Dissertations, & Professional Papers

Fences pose significant challenges to wildlife movement, but their effects are difficult to quantify because fence location and fence type data are lacking on a global scale. We developed a fence location and density model in southwest Montana, USA to provide data to researchers and managers, and test whether previous models could be applied to a new region and retain suitable levels of statistical accuracy. Our model used local expert opinion to inform how road, land cover, and ownership spatial layers interacted to predict fence locations. We validated the model against fence data collected on random 3.2 km road transects …

Environmental Discriminators For Significant Tornadoes And Hail In The U.S. Using Proximity Soundings, Cody Michael Converse

Graduate Research Theses & Dissertations

Over the last 50 years, the United States has experienced an increase in severe storm events that produced $1 billion in damages or greater. Much of this loss is attributed to significant tornadoes and hail associated with deep, moist convection. Improving forecasts for these significant events assist in mitigating the impacts of these events. Previous work has identified statistically significant environmental parameters associated with severe thunderstorms, but more research is needed in identifying statistically significant ingredients associated with environments that produce significant tornadoes and hail.

This thesis aims to answer the following question: “Can diagnostics commonly used to forecast for …

Situating Asian American Environmental (In)Justices Through Radical History Walking Tours, Yuxin Zhou

Pomona Senior Theses

By analyzing two radical history walking tours in Seattle, WA, and Berkeley, CA, this thesis aims to examine how Asian American communities can find their places in the U.S. environmental movement. I argue that these walking tours provide generative pedagogical tools to engage the general public to unpack the complex Asian American history embedded within urban spaces. I also articulate how these walking tours have the capacity to situate environmental struggles and activism within urban spaces, illustrating that various Asian American social and political activism has always been addressing environmental concerns. Furthermore, I argue that these walking tours of Asian …

Understanding And Measuring Net Positive Business Strategies, Luke Ruffner Robinson

Graduate Student Theses, Dissertations, & Professional Papers

Despite their attempts to mitigate ecological impacts through sustainability initiatives, businesses are a major cause of the world's ecological problems. Some progressive businesses are attempting to move beyond “net zero” in terms of achieving neutral environmental impacts and instead are now pursuing a goal of net positive. Net positive refers to the idea that business activities could contribute value-added benefits to earth’s ecological systems, for example, by using technologies that sequester and store carbon. However, except for a handful of high-profile corporate case studies, little is known about how companies are developing their strategies to become net positive and …

Cal Poly Humboldt theses and projects

This study contributes to the existing, yet small, cadre of research using photo elicitation to investigate the place meanings of people living in a natural-amenity-rich area. Ten current and former residents of Del Norte County, California took pictures of and discussed in an interview the people, places, and attributes they found valuable or meaningful about that place. The primary focus of the photos and interviews was how these natural amenities, in particular Jedediah Smith Redwoods State Park, impacted or influenced residents’ place meanings. Three major themes of place meaning were identified from the interviews: Environment-Landscape, Human-Social, and Recreation-Exploration. Each contained …

Addressing The Skills Gap Of Geospatial Professionals In The Fourth Industrial Revolution, Shannon Marie Doyle

Walden Dissertations and Doctoral Studies

Leaders of geospatial organizations are ill-prepared to manage rapid technological change critical to environmental and economic development due to an outdated list of technical competencies. However, there is a lack of consensus in the geospatial industry concerning the desired technical competencies of organizations and a gap in the literature regarding future trends when defining additional geospatial technical competencies. Therefore, the purpose of this qualitative modified Delphi study was to determine how a nationwide panel of experts in the geospatial industry viewed the desirability and practicability of forward-looking technical competencies of geospatial professionals. The research questions for this study were grounded …

Alaska National Parks And Indigenous Peoples: Collaboration For A Protected Future, Siobhan Mctiernan

Dissertations and Theses @ UNI

This research examines the relationships between National Parks and Indigenous communities across the state of Alaska. National Parks as a government agency can be perceived in a negative way; but in Alaska, while there are issues and limitations, parks are going beyond policy guidelines to work with communities and help build a resilient future for both the parks and the local people. This work dives into the National Parks policies and practices, projects resulting from engagement of community stakeholders, perceptions of engagement, community capitals, and sustainable development. In particular, the study investigates how these policies, practices, and interactions ultimately contribute …

Predictive Geohazard Mapping Using Lidar And Satellite Imagery In Missouri And Oklahoma, Usa, Olufeyisayo B. Ososami

Doctoral Dissertations

”Light Detection and Ranging (LiDAR) and satellite imagery have become the most utilized remote sensing technologies for compiling inventories of surficial geologic conditions. Point cloud data obtained from multi-spectral remote sensing methods provide a detailed characterization of the surface features, in particular, the detailed surface manifestations of underlying geologic structures. When combined, point clouds eliminate bias from visual inconsistencies and/or statistical values. This research explores the competence of point clouds derived from LiDAR and Unmanned Aerial Systems (UAS) as a predictive tool in evaluating various geohazards. It combines these data sets with other remote sensing techniques to evaluate the sensitivity …

Flooding And Industrial Swine Farming In North Carolina: Implications Of Natech Hazards On The Assessment Of Environmental Justice, Jacob Ramthun

Theses and Dissertations

“Natech” events, in which natural hazards trigger anthropogenic hazards, are becoming increasingly common. Methodologies for measuring the impact of natech events on environmental justice assessments are lacking, particularly in rural scenarios. This study used additive, multiplicative, and z-score threshold methods of combining the density of industrial swine farms in eastern North Carolina and the presence of flood risk to determine whether or not natech risk exhibits emergent socioeconomic indicators and whether areas of high natech constitute environmental injustice. The multiplicative and z-score threshold methods generated variables representing natech risk to compare to socioeconomic indicators, as well as statistically significant hotspots. …

A Gis-Based Risk Assessment For Fire Departments: Case Study Of Richland County, Sc, Tracy Whelen

Theses and Dissertations

Risk assessments enable fire departments to be better prepared for future incidents and to engage in more effective prevention activities. A combination of physical, demographic, and behavioral risk factors combined form a community’s level of risk. This research shows how spatial and nonspatial statistical methods can be used within a GIS framework to create such a risk assessment, with the Columbia-Richland Fire Department in Richland County, SC being used as a case study. Hot spot analysis and thematic mapping of incident rates were used to assess the first research question – what is the spatial variability of structure fires, carbon …

Village-Temple Consciousness In Two Jaffna Tamil Villages In Post-War Sri Lanka, Pathmanesan Sanmugeswaran

Theses and Dissertations--Anthropology

This dissertation investigates how community rebuilding is occurring in a gravely damaged, post-conflict society. Specifically, it looks at how people in two villages in Tamil, Hindu, Jaffna, Sri Lanka, are using their ‘sense of place’ and ‘place-making practices’ or what I call here their ‘village-temple consciousness’ or village consciousness, to maintain and rebuild their communities after war to make them, once again, places in which they feel a comfortable sense of belonging. This is a comparative study because Inuvil and Naguleswaram were affected differently by the Sri Lankan civil war. That is, while Inuvil, was physically damaged and socially disrupted …
