Spatial And Seasonal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot Jan 2022

Spatial And Seasonal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot

Dissertations and Theses

Microplastics are a pollutant of growing concern and are ubiquitous in a variety of environmental compartments. The majority of microplastics research to date has been conducted in marine waters, and less is known regarding the sources and delivery pathways of microplastics in urban rivers. The first chapter is comprised of a review of the scientific literature regarding the spatial and temporal factors affecting global freshwater microplastic distributions and abundances. Microplastic spatial distributions are heavily influenced by anthropogenic factors, with higher concentrations reported in regions characterized by urban land cover, high population density, and wastewater treatment plant effluent. Temporal variables of …

Tibetan Dust Accumulation Linked To Ecological And Landscape Response To Global Climate Change, Xianmei Huang, Xiaodong Miao, Qiufang Chang, Jiemei Zhong, Joseph A. Mason, Paul R. Hanson, Xianjiao Ou, Liubing Xu, Zhongping Lai

School of Natural Resources: Faculty Publications

The Tibetan Plateau (TP) is a hotspot of earth system research, and understanding its landscape and ecosystem evolution has been hampered by the lack of time-constrained geological records. Geochronological data from 14 loess sites covering a large region in the Tibetan interior show that the TP loess, rather than accumulating during glacial periods, began aggrading at either 13.4 ± 0.4 or 9.9 ± 0.2 ka. An ecological threshold was crossed, when warmer and wetter conditions resulted in increased vegetation cover enabling dust trapping. This dust accumulation model is out of phase with that of the Chinese Loess Plateau (CLP) where …


Unmanned Aerial Remote Sensing Of Coastal Vegetation: A Review, Grayson R. Morgan, Michael E. Hodgson, Cuizhen Wang, Steven R. Schill Jan 2022

Unmanned Aerial Remote Sensing Of Coastal Vegetation: A Review, Grayson R. Morgan, Michael E. Hodgson, Cuizhen Wang, Steven R. Schill

Faculty Publications

Coastal wetlands contribute greatly to our coasts economically and ecologically. The utility of coastal wetland vegetation, along with the multitude of dynamic forces they encounter, suggests the need of regular monitoring for sustainable management. While traditional in situ survey methods and remote sensing from space and manned platforms have provided means to monitor and study the coastal zone thus far, the recent developments of small unmanned aerial systems (sUAS) fill a small void between traditional in situ survey methods and the high spatial resolution of manned aircraft imagery. As an on-demand personal remote sensing device, an sUAS can be deployed …

A Review Of Environmental Vulnerabilities Related To Nepal’S Graduation Process From Least Developed To A Developing Country Status, Ambika P. Adhikari, Keshav Bhattarai, Basu Sharma

Himalayan Research Papers Archive

Nepal has long aspired to graduate from the Least Development Country (LDC) to Developing Country category as defined by the United Nations system. Nepal had met two of the three graduating criteria and could have technically graduated from the LDC status in 2015. However, based on the Nepal government’s request to defer the review, the new 2021 assessment by the United Nations Committee for Development Policy (CDP) recommended that the country should graduate from the LDC status by 2026. The graduation requires not only meeting pre-defined development-related thresholds, but also maintaining sustained improvements in at least two consecutive assessments in …

A catastrophic flood occurred on 7 February 2021 around 10:30 AM (local time) in the Rishiganga River, which has been attributed to a rockslide in the upper reach of the Raunthi River. The Resourcesat 2 LISS IV (8 February 2021) and CNES Airbus satellite imagery (9 February 2021) clearly show the location of displaced materials. The solar radiation observed was higher than normal by 10% and 25% on 6 and 7 February 2021, respectively, however, the temperature shows up to 34% changes. These conditions are responsible for the sudden change in instability in glacier blocks causing deadly rock-ice slides that …


Detecting And Visualizing Observation Hot-Spots In Massive Volunteer-Contributed Geographic Data Across Spatial Scales Using Gpu-Accelerated Kernel Density Estimation, Guiming Zhang Jan 2022

Detecting And Visualizing Observation Hot-Spots In Massive Volunteer-Contributed Geographic Data Across Spatial Scales Using Gpu-Accelerated Kernel Density Estimation, Guiming Zhang

Geography and the Environment: Faculty Scholarship

Volunteer-contributed geographic data (VGI) is an important source of geospatial big data that support research and applications. A major concern on VGI data quality is that the underlying observation processes are inherently biased. Detecting observation hot-spots thus helps better understand the bias. Enabled by the parallel kernel density estimation (KDE) computational tool that can run on multiple GPUs (graphics processing units), this study conducted point pattern analyses on tens of millions of iNaturalist observations to detect and visualize volunteers’ observation hot-spots across spatial scales. It was achieved by setting varying KDE bandwidths in accordance with the spatial scales at which …

Exploring Perspectives Of The Validity, Legitimacy And Acceptability Of Environmental Valuation Using Q Methodology, Rob Tinch, Isaac Ankamah-Yeboah, Claire Armstrong

Journal of Ocean and Coastal Economics

The extension of market systems and economic appraisal methods to the natural world and allocation of scarce resources is highly controversial and viewed by some as unethical. This has resulted in questions about the appropriate role of valuation and appraisal methods in informing policy and decision-making. We address this issue by assessing the different points of view that exist in marine research, management and policy communities regarding the estimation of monetary values for marine ecosystems and services and their use in appraisal and policy settings. The principal perspectives emerging from a Q-sort survey of x respondents reveal a clear distinction …

Blue Growth: A Transitions Approach To Developing Sustainable Pathways, Christina Kelly, Ben Mcateer, Frances Fahy, Liam Carr, Daniel Norton, Desiree Farrell, Rebecca Corless, Stephen Hynes, Zacharoula Kyriazi, Agnès Marhadour, Regis Kalaydjian, Wesley Flannery

Journal of Ocean and Coastal Economics

The sustainable management of Blue Growth is an urgent issue for coastal states. Marine industries have rapidly expanded over the last two decades and this is projected to continue with the European Green Deal and post-COVID economic recovery policies. The intensification of Blue Growth could have adverse socio-ecological implications and must, therefore, be managed in terms of sustainability, natural resource boundaries, and coastal community well-being. Managing Blue Growth in a sustainable manner however, is challenging due to the longstanding inefficiencies and inertia of existing marine governance regimes. Adopting a transitions approach has been advanced as a way of steering regime …


In The Middle Of Appalachia: Balancing Teacher Talk With Student Discourse, Ronald V. Morris, Denise Shockley, Sonya Davis Jan 2022

In The Middle Of Appalachia: Balancing Teacher Talk With Student Discourse, Ronald V. Morris, Denise Shockley, Sonya Davis

The Councilor: A National Journal of the Social Studies

Appalachian students co-constructed knowledge with their teacher while examining a non-fiction book about Thanksgiving. Fifth grade students used an informational trade book to promote student discourse while using text-based evidence. Students learned about Native Americans and Pilgrims as they engaged in student discourse balanced with teacher talk. Students used an inquiry arc that involved questioning texts and examining sources, and inquiry helped students to investigate narrative text as a source of data. Students used inquiry to enhance their metacognition about historical events. Students exercised agency as they recounted family history and their heritage as part of their memory. Remembering was …


Formative Assessment To Help Students Decode, Process, And Evaluate Social Studies Information, Cory Callahan Jan 2022

Formative Assessment To Help Students Decode, Process, And Evaluate Social Studies Information, Cory Callahan

The Councilor: A National Journal of the Social Studies

Here the author explores formative assessment within a context of research-based social studies instructional approaches. While the notions of inquiry, alternative assessment, disciplinary thinking and interpretation, and using visual documents as powerful resources each provide an important element of conceptual structure, this article purposefully concentrates on the process of constructive evaluation. The author posits a wise-practice routine for developing formative assessment practices that cohere with criteria-based assessment and its tendency to describe what students did well, what they could have done differently to improve their recent academic performance, and, importantly, how they can improve subsequent academic performance. The article also …


History Or Heritage? An Analysis Of Ghana’S Primary School History Curriculum, Charles Adabo Oppong Jan 2022

History Or Heritage? An Analysis Of Ghana’S Primary School History Curriculum, Charles Adabo Oppong

The Councilor: A National Journal of the Social Studies

Abstract

At a time that history has gained its place in Ghana’s basic school curriculum, considerable differences of opinion arise, not about the subject’s significance in the school curriculum but concerning the legitimacy of the subject title - that is, whether or not the subject should be referenced ‘History of Ghana’ or ‘Heritage of Ghana’. The different opinions reflect Lowenthal’s (1998) observation that history and heritage are separate disciplines. However, the two subjects are often used interchangeably (Mermion, 2012) and “are habitually confused with each other” (Lowenthal 1998, p. x). While expert academics may be at ease with the distinctions …


Educational Inequality In The Kebribeyah Somali Refugee Camp In Ethiopia: An Autoethnography, Ahmed Muhumed, Saleh Ahmed Jan 2022

Educational Inequality In The Kebribeyah Somali Refugee Camp In Ethiopia: An Autoethnography, Ahmed Muhumed, Saleh Ahmed

Global Studies Faculty Publications and Presentations

Due to the Somali Civil War of 1991, more than 10,000 Somali refugees resettled in Kebribeyah, a town in the Somali region of Ethiopia. For nearly three decades, the local and resettled refugee communities shared the resources the region had to offer, adopted a new common cultural norm, and fostered some levels of social cohesions. It is the education sector, however, that caused social conflicts and hatred between resettled Somalis and the native Somali-Ethiopians. Currently, the education of Somali refugee children is funded by various international organizations, such as the United Nations. On the contrary, the local Somali-Ethiopian children pay …


Pronounced Increases In Nitrogen Emissions And Deposition Due To The Historic 2020 Wildfires In The Western U.S., Patrick C. Campbell, Daniel Tong, Rick Saylor, Yunyao Lii, Siqi Ma, Xiaoyang Zhang, Shoba Kondragunta, Fangjun Li Jan 2022

Pronounced Increases In Nitrogen Emissions And Deposition Due To The Historic 2020 Wildfires In The Western U.S., Patrick C. Campbell, Daniel Tong, Rick Saylor, Yunyao Lii, Siqi Ma, Xiaoyang Zhang, Shoba Kondragunta, Fangjun Li

GSCE Faculty Publications

Wildfire outbreaks can lead to extreme biomass burning (BB) emissions of both oxidized (e.g., nitrogen oxides; NOx= NO+NO2) and reduced form(e.g., ammonia; NH3) nitrogen (N) compounds. High N emissions aremajor concerns for air quality, atmospheric deposition, and consequential human and ecosystemhealth impacts. In this study, we use both satellite-based observations and modeling results to quantify the contribution of BB to the total emissions, and approximate the impact on total N deposition in the western U.S. Our results show that during the 2020 wildfire season of August–October, BB contributes significantly to the total emissions, with a satellite-derived fraction of NH3 to …


Festivals And The City: The Contested Geographies Of Urban Events, Andrew Smith, Guy Osborn, Bernadette Quinn Jan 2022

Festivals And The City: The Contested Geographies Of Urban Events, Andrew Smith, Guy Osborn, Bernadette Quinn

Books / Book chapters

This book explores how festivals and events affect urban places and public spaces, with a particular focus on their role in fostering inclusion. The ‘festivalisation’ of culture, politics and space in cities is often regarded as problematic, but this book examines the positive and negative ways that festivals affect cities by examining festive spaces as contested spaces. The book focuses on Western European cities, a particularly interesting context given the social and cultural pressures associated with high levels of in-migration and concerns over the commercialisation and privatisation of public spaces.

The key themes of this book are the quest for …

Event Tourism, Public Policy And Socio-Cultural Development In Dublin, Bernadette Quinn, Ana Maria Fernandes Dr, Theresa Ryan Dr Jan 2022

Event Tourism, Public Policy And Socio-Cultural Development In Dublin, Bernadette Quinn, Ana Maria Fernandes Dr, Theresa Ryan Dr

Articles

In a highly globalised, competitive world, urban strategies often highlight festivals and events as activities which can attract tourists and investors, extend the tourism season and boost the economy. Event tourism as a term is now well established in the tourism lexicon, however, it is usually employed in quite a limited way that offers only partial insights into a complex phenomenon. To redress this deficit, this paper examines the case of Dublin, where for the last twenty-five years, policy-makers have been using festivals and events to boost the city’s international standing. The aim is to investigate whether policy-makers can strategically …

Guidebook For Omaha's Urban Geology And Anthropocene Nebraska Well Drillers 2022 Field Trip, Harmon Maher, Ashlee L. Dere, Melina Luethje

Geography and Geology Faculty Books and Monographs

This geologic field trip focus is somewhat atypical but arguably reflects an ongoing evolution within the geosciences. Instead of traveling out into rural settings to look at outcrops and the stratigraphy exposed, or rural landforms and their geologic history, this field trip is focused on built and engineered environments in the Omaha area and the ‘modified’ associated geologic processes such as surface and groundwater flow, weathering, and soil formation. The ongoing evolution includes an increase in a multidisciplinary system science approach and is driven by a need to address environmental and resource management challenges using new tools and conceptual frameworks. …


“It’S Real”: Experiences Of Family Homelessness In Fort Worth, Texas, Bernd Scheffler, Dale Brooker Phd. Jan 2022

“It’S Real”: Experiences Of Family Homelessness In Fort Worth, Texas, Bernd Scheffler, Dale Brooker Phd.

Pursue: Undergraduate Research Journal

Introduction: Despite the common public image of homelessness (read: a single “vagrant” person), families with children represent one-third of the homeless population—an especially-serious social problem since family homelessness has long-term negative impacts on two generations simultaneously. This interdisciplinary study examined the complexities of family homelessness in Fort Worth, Texas.

Methods: A literature review outlined pathways into family homelessness, shared experiences, and common intervention strategies. An original qualitative study followed, employing a phenomenological approach to interview families in a local rapid-rehousing program. Open-ended questions allowed free descriptions of personal realities. Audio-recorded responses were analyzed for relevant themes, commonalities, and variations.

Understanding The Impacts Of Urban Agriculture In Gentrifying Neighborhoods In Denver, Kate Johnson

Electronic Theses and Dissertations

Urban Agriculture is prominent in cities across the United States and has been studied in relation to food security, sustainability, and gentrification. Urban agriculture is context specific and can include individual gardens, community gardens, guerilla gardening, and urban farms. Urban agriculture is a product of the community it is based in, depending on politics, history, and social environments. For these reasons, the relationship between urban agriculture and the community is an area where more research is needed. This thesis explores the role visible gardens play in community building, sustainability, and food security in gentrifying neighborhoods in Denver. Through qualitative methods …


Exploring Youth Relationships With Nature Using Qualitative Gis, Corey J. Martz Jan 2022

Exploring Youth Relationships With Nature Using Qualitative Gis, Corey J. Martz

Electronic Theses and Dissertations

Understanding youth relationships with nature—what nature is, where nature is located, and why nature is meaningful—is important for a range of contemporary issues, from promoting health and well-being to advancing a sustainable future. Relationships with nature are profoundly influenced by the lived experiences of youth, as they form social connections, have fun, learn, and go about their lives across an array of places—residences, schools, trip destinations, and places in between. One key to exploring youth relationships with nature, therefore, is engaging youth to document their experiences of nature in relation to specific places and developing methods that support them to …

Care Infrastructure Accessibility And The Gender Wage Gap – A Way To Improve Women’S Ability To Equitably Engage In The Paid Labor Market?, Julia Schinnenburg

Electronic Theses and Dissertations

World-wide, women are less integrated into the labor force than men and if they are, they earn considerably less on average. This unequal treatment of women results in negative consequences for all members of society, as it harms women’s financial realities and also affects women’s care receivers due to a lack of resources that women can spend on their care giving. The research presented analyses how much the institution of better accessible care infrastructure could improve women’s ability to work for pay and decrease their daily workloads. The extent to which improved care infrastructure accessibility affects women’s lives is determined …

Geovisualization And Open-Source Web Mapping Of Big Origin-Destination Data, A Test Case, Joseph Hiebert Jan 2022

Geovisualization And Open-Source Web Mapping Of Big Origin-Destination Data, A Test Case, Joseph Hiebert

Electronic Theses and Dissertations

Migration plays a key role in determining the health and success of cities, counties, and countries. It also plays a key role in determining the health and wellbeing of the individuals and families that undergo a migration event. This has led many scholars to map and study global migration patterns to understand how and why people move. While migration data are powerful, the origin-destination (O-D), tabular format of the data can be hard to interpret. To make O-D data more powerful, geographers can lean on computer cartography and new geovisualization techniques to help decision makers make sense of large, complex …
