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 …

Land – Atmosphere – Meteorological Coupling Associated With The 2015 Gorkha (M 7.8) And Dolakha (M 7.3) Nepal Earthquakes, Feng Jing, Ramesh P. Singh, Xuhui Shen

Mathematics, Physics, and Computer Science Faculty Articles and Research

Multiple parameters (brightness temperature, soil moisture, surface latent heat flux, surface air temperature and carbon monoxide) before and after the 2015 Nepal M7.8 Gorkha main earthquake and M7.3 Dolakha aftershock were analysed using satellite observation data. The thermal anomalies from optical and microwave data appear about two months prior to the 2015 Gorkha earthquake. Some of the parameters show anomalous changes at different altitudes about 20 days prior to the main earthquake event and 10 days prior to the strong aftershock. Our results show that pre-earthquake anomalous signals propagate from the in situ to the top of atmosphere, and the …

The Effects Of Constructed Wetlands On Metal Solubilization And Bioavailability In Passive Mine Remediation, Elizabeth Cochran

Electronic Theses and Dissertations

The legacy of coal mining in Appalachia has left many watersheds impacted by abandoned mine drainage. The drainage degrades streams, groundwater and habitats with acidity and toxic heavy metals. The Lowber Passive Remediation System has been in operation since 2004 to remediate high amounts of dissolved Fe, SO₄, Al, and Mn. The site consists of six settling ponds and an extensive wetlands at the finish. This study investigated the resolubilization of Fe and Mn in the wetlands and the role of bacteria in resolubilization. During three seasons, field measurements of water quality and lab analysis of Fe, Mn, …

Water Quality Assessment Of Deer Lakes County Park Before, During And After Unconventional Shale Gas Drilling, Daniel Robinson

Electronic Theses and Dissertations

Allegheny County, Pennsylvania, signed a lease to allow unconventional natural gas extraction from Marcellus Shale beneath Deer Lakes County Park in 2014. The park has three man-made lakes and four waterways that eventually flow into the Allegheny River. Drilling commenced in early 2016, and there are now five producing wells. The park has an extensive abandoned coal mine network and several abandoned oil and gas wells. Thus, an independent water quality study was undertaken beginning in July 2015. Samples from seven different sites in the park were used to establish a water quality baseline prior to the drilling. Monthly sampling …

Quest

Independent Research Paper

Research in progress for PHYS 2426: University Physics II

Faculty Mentor: Raji Kannampuzha, Ph.D.

The following paper represents research work done by students in a University Physics 2426 class, the second half of a two-semester introductory course in physics. It is a calculus-based physics course, intended primarily for physics, chemistry, math, and engineering majors. Students are introduced to the concept of academic research by learning to ask research-focused questions and then use the library resources to pursue outside research to find answers. For this assignment, students are asked to investigate a physical science, biological science, or technology …

Bias Reduction In Machine Learning Classifiers For Spatiotemporal Analysis Of Coral Reefs Using Remote Sensing Images, Justin J. Gapper

Computational and Data Sciences (PhD) Dissertations

This dissertation is an evaluation of the generalization characteristics of machine learning classifiers as applied to the detection of coral reefs using remote sensing images. Three scientific studies have been conducted as part of this research: 1) Evaluation of Spatial Generalization Characteristics of a Robust Classifier as Applied to Coral Reef Habitats in Remote Islands of the Pacific Ocean 2) Coral Reef Change Detection in Remote Pacific Islands using Support Vector Machine Classifiers 3) A Generalized Machine Learning Classifier for Spatiotemporal Analysis of Coral Reefs in the Red Sea. The aim of this dissertation is to propose and evaluate a …

Climate Change Governance And The Politics Of Scale: Evaluating Local Climate Protection Policies And Practices In The United States And Germany, Ayure-Inga Mark Anthony Agana

Graduate Theses and Dissertations

When it became evident that the issue of climate change needed to be acted upon, it was projected as a global scale problem. To make this rhetoric concrete, the international relations logic that ‘regimes’ of cooperating nation-states are the most feasible approach to solving problems that are global in nature was adopted. While the national level has performed poorly in climate change mitigation action, as exemplified by the United States’ refusal to ratify the Kyoto Protocol, Canada’s subsequent withdrawal from the Kyoto Protocol in 2011 after initial ratification and, more recently, the United States withdrawal from the Paris Accord, a …

The Potential Acidification Of The Mulberry River, Arkansas, Jason Richard Burgess-Conforti

Graduate Theses and Dissertations

The Mulberry River is a 110 km long tributary of the Arkansas River in northwest Arkansas and has been designated as a National Wild and Scenic River since 1992. In 2008, the Mulberry River was added to the 303(d) list of impaired water bodies due to the low pH of a 14.6 km segment of the river which has since increased to 68.7 km. To date, there has been little research performed on the Mulberry River and long-term routinely sampled water quality data is unavailable. The objectives of this dissertation were 1) to evaluate changes in water quality of the …

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)]. The overall infiltration rate …

Assessing The Roles Of Seabird Harvest And Non-Native Rats On Grenadine Seabird Nesting Performance, Wayne Anthoony Smart

Student Theses and Dissertations

Seabird populations are declining worldwide. Two major causes of decline are non-native predators and seabird (indirect or direct) overexploitation; these have been suspected but not assessed in the Caribbean region, including in the southern Grenadine islands. Using cameras, questionnaire surveys, and nest monitoring, I explored the potential of invasive predator presence and seabird harvest in affecting nesting productivity of five species in five uninhabited islands during 2014–2017. Overall, nesting productivity increased (n = 567 nests) despite the confirmed presence of non-native rats. However, my survey of Grenada residents (n = 32 responses) and physical evidence found on the islands (e.g., …
