Do Corporate Owned Adaptive Learning Platforms Perpetuate Banking Style Learning? Integrating Technology For Activism Into Transformational Sustainability Education, Tina M. Garner

Leadership for Sustainability Education Comprehensive Papers

We live in a world that tends to be controlled by corporations. The public school system should be wary of the problems that corporate control has on education. Even though public schools should not have corporate influence, the fact remains that they do, and this perpetuates Freire's banking style learning. Through time, the corporate influence in education was through educational materials such as book sales. Since the decline of the use of books and the growth of the use of technologies, corporations have followed suit through the sales of Adaptive Learning Platforms. Through leveraging the technology which students enjoy using, …

Social Interactions Do Not Drive Territory Aggregation In A Grassland Songbird, S.K. Winnicki, S.M. Munguia, E.J. Williams, W.A. Boyle

United States National Park Service: Publications

Understanding the drivers of animal distributions is a fundamental goal of ecology and informs habitat management. The costs and benefits of colonial aggregations in animals are well established, but the factors leading to aggregation in territorial animals remain unclear. Territorial animals might aggregate to facilitate social behavior such as (1) group defense from predators and/or parasites, (2) cooperative care of offspring, (3) extra-pair mating, and/or (4) mitigating costs of extra-pair mating through kin selection. Using experimental and observational methods, we tested predictions of all four hypotheses in a tallgrass prairie in northeast Kansas, United States. Grasshopper Sparrow (Ammodramus savannarum) males …

Vegetation Monitoring At Homestead National Monument Of America, Nebraska, 1998–2017, Sherry A. Leis

How Pennsylvanians Define Environmental Justice, Kayla Hofmann

Sociology Summer Fellows

The Pennsylvania Department of Environmental Protection (DEP) defines an environmental justice area as any census tract that partially or wholly includes a 30 percent or greater minority population or 20 percent or more of a population living in poverty. However, little is known about how the average Pennsylvanian defines environmental justice, hindering our ability to determine whether the current definition is adequate. Using transcripts from nine listening sessions on the DEP’s tour of affected counties, I address 3 questions: (1) How do people define environmental justice? (2) What do people think are the most pressing issues in each county? And …

Like Father, Like Son: Modelling Masculinity For The Ethical Leadership Of President Theodore Roosevelt, Elizabeth Summerfield

The Journal of Values-Based Leadership

President Theodore Roosevelt is frequently portrayed as a rugged, hypermasculine cowboy. But this depiction ignores the powerful modelling for masculine leadership provided by his father, Theodore Roosevelt senior. A closer examination of the private and public spheres that framed the latter’s life offers another route into understanding the ethical and rational motivations that characterised his progressive Presidency, not least in the area of natural resource management, where his policy innovations were both unprecedented and sustained over time. What emerges is a more complex portrait than the above stereotype, a leader who used his heart, head and experience to think and …

Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood

Journal of Ocean and Coastal Economics

Disease and overfishing have led to a dramatic decline in wild populations and subsequent harvests of the eastern oyster Crassostrea virginica over the past few decades in Delaware and other states along the Atlantic Coast. However, in addition to their value as food to consumers, oysters, whether wild populations or cultured stocks, can provide ecosystem services such as nutrient removal, which may result in localized water quality improvements. Consequently, recent policies in Delaware have sought to establish and grow an oyster aquaculture industry. However, a key challenge to achieving efficient levels of industry growth and water quality improvements is that …

Engaged Communication Scholarship For Environmental Justice: A Research Agenda, Chad Raphael

Communication

As a discipline of crisis and care, environmental communication needs to address questions of environmental justice. This article argues that the most appropriate approach to studying environmental justice communication is engaged scholarship, in which academics collaborate with community partners, advocates, and others to conduct research. The article reviews prior engaged communication scholarship on environmental justice, and proposes four streams of future research, focused on news and information, deliberation and participation, campaigns and movements, and education and literacy.

Teacher Perceptions Of Environmental Science In Rural Northwestern New Mexico Public Schools, Marie Quiahuitl Julienne

Organization, Information and Learning Sciences ETDs

In this study, I explored what teachers perceive as the factors that impact their teaching of environmental science in rural secondary level schools in northwestern New Mexico. I adapted Bronfenbrenner’s (1994) ecological systems model, based on four environmental subsystem levels (microsystem, mesosystem, exosystem, and macrosystem), as the conceptual framework to address the major research question of this study, and developed 18 interview questions to explore teachers’ perceptions of factors that influence their teaching of environmental science. I investigated the perspectives science teachers have about environmental science topics and the influences they perceive that affect how they teach environmental science, and …

Understanding Ngos And Their Effectiveness Through A Comparative Study Of Their Role In Redd+, Jessica Russo

Political Science Student Scholarship

This thesis explores the following question: what roles do NGOs play and how effective may they be in efforts at global governance? Through a comparative case study analysis of NGOs advocating for Reducing Emissions for Deforestation and forest Degradation (REDD+) and NGOs implementing REDD+ projects, specifically the Surui Forest Carbon Project located in the state of Rondônia, Brazil, I examine whether NGOs are more effective taking on the role as advocates or policy implementers. For this work, I will argue that independent of the multiplicity of roles that NGOs play, their effectiveness is a function of the level of their …

I will watch the water begin to drown the state, taking Florida’s many little known histories along with it. This thesis serves as a document of Floridian life during the Anthropocene.

Within this thesis, I tell the story of …

Assessing The Impacts Of Gold Mining Deforestation On The Giant Otter (Pteronura Brasiliensis) In Madre De Dios, Peru, Erica Carcelen

Sustainability and Social Justice

Gold mining activity is highly prevalent in the Madre de Dios region, Peru. This activity poses large environmental impacts including deforestation, sedimentation of rivers, and pollution from mercury used during extraction. Mining activity is a major threat to the endangered giant otter as it destroys its preferred riverine habitat. Moreover, mercury used during gold extraction bio-accumulates in fish, which constitutes the entirety of their diet. In order to conserve the giant otter, it is necessary to identify conservation priority areas. In a reactive conservation planning approach, the objective of this work was to prioritize areas suitable as giant otter habitat …

A Systematic Assessment Of Socio-Economic Impacts Of Prolonged Episodic Volcano Crises, Justin Peers

Electronic Theses and Dissertations

Uncertainty surrounding volcanic activity can lead to socio-economic crises with or without an eruption as demonstrated by the post-1978 response to unrest of Long Valley Caldera (LVC), CA. Extensive research in physical sciences provides a foundation on which to assess direct impacts of hazards, but fewer resources have been dedicated towards understanding human responses to volcanic risk. To evaluate natural hazard risk issues at LVC, a multi-hazard, mail-based, household survey was conducted to compare perceptions of volcanic, seismic, and wildfire hazards. Impacts of volcanic activity on housing prices and businesses were examined at the county-level for three volcanoes with a …

Landuse And Soil Property Effects On Infiltration And Soil Aggregate Stability In The Lower Mississippi River Valley, Rebecca Lynn Anderson

Graduate Theses and Dissertations

Following European settlement of the Lower Mississippi River Valley (LMRV), agricultural expansion and unsustainable, agriculturally related practices have caused groundwater depletion, soil erosion, and surface water contamination by eroded sediments and sediment-bound nutrients to become major environmental threats to the region. The objective of this study was to evaluate the effects of common landuses [i.e., native prairie, deciduous forest, coniferous forest, Conservation Reserve Program (CRP) grassland, and conventional-tillage (CT) and no-tillage (NT) agriculture] on surface water infiltration and aggregate-stability-related properties [i.e., water-stable macroaggregate (WSA) size distribution, total water-stable macroaggregate (TWSA) concentration, and mean weight diameter (MWD)].
