A Study Of The Collisional Evolution Of Orbital Debris In Geopotential Wells And Geo Disposal Orbits, Christina R. Diaz

Master's Theses

This thesis will present the effects of the orbital debris evolution in two key areas: the geosynchronous disposal orbit regime known as “graveyard” and the two geopotential wells found in 105◦ W and 75◦ E longitude bins. After developing a GEO specific orbit propagator for NASA Johnson Space Center’s Orbital Debris Of- fice, collisions were simulated throughout these regimes using a low velocity breakup model. This model considered the effects of perturbations particularly non-spherical Earth effects (specifically sectorial and zonal harmonics), lunar effects, third body effects and solar radiation pressure effects. The results show that CDPROP does well in simulating …

Ecology And Structure Of Black Bear (Ursus Americanus) Populations In The Interior Highlands Of Arkansas, Thea Vandervelde Kristensen

Graduate Theses and Dissertations

In the Interior Highlands of Arkansas, Missouri, and Oklahoma, over-harvest, extensive logging, and reductions of habitat availability by other means contributed to the decline of black bears (Ursus americanus). Bears were extirpated from the majority of the region by the 1940's Oklahoma by 1915 and from Missouri by 1931. From 1958-1968, the Arkansas Game and Fish Commission undertook a reintroduction to the Ouachita and the Ozark National Forests in Arkansas. The successful growth and expansion of the released population caused these efforts to be considered one of the most successful reintroductions of carnivores. In this dissertation, I sought to examine …

Evaluation Of Broiler Litter Heat Production During Windrowing & Nitrogen Based Gas Emission Mitigation Using Biofilter, Min Lei

Graduate Theses and Dissertations

Ammonia emission from animal feeding operations (AFOs) has negative effects on environment and animals' health. Thus measuring and mitigating ammonia emission from AFOs is important for environmental protection. In chapter I, different ammonia measurements were discussed and a mitigation technology- biofilter was represented.

In-house windrowing of built-up litter has been used by broiler producers to reduce pathogen loads and rejuvenate litter for the next flock. When litter is piled up for an extended period during downtime, heat generated by the litter pile can become a substantial heat source due to the metabolism of microorganisms. In chapter II, heat production rates …

Updated Pressure And Temperature Determinations For The Metapelites Of The Western Hudson Highlands, Ny, Eric W. Sonnenwald

Theses, Dissertations and Culminating Projects

Pelitic sedimentary material was deposited along the eastern margin of North America in the Mesoproterozoic (~1300-1200 Ma) in an active continental arc basin setting and was subsequently metamorphosed during the Ottawan Orogeny (~1080-1030 Ma) as a part of a closing ocean basin between two continents (Volkert and Drake, 1999). The resulting metapelitic gneisses now exposed in the western Hudson Highlands in Harriman State Park, New York were analyzed to determine the sedimentary protolith and the peak metamorphic pressure-temperature (P-T) conditions during the Ottawan Orogeny that affected this region during the final assembly of Rodinia. The protolith, a clay-bearing arkosic sandstone, …

Natural Resource Management Knows No Bounds: A Case Study Of The Cache River Joint Venture Partnership, Jennifer Ann Behnken

Theses

In southern Illinois, multiple state, federal, and private ownerships are implementing various management tactics in the Cache River watershed. Although some aspects are coordinated under the Cache River Joint Venture Partnership (CRJVP), individual agencies and entities retain specific ownership priorities and approaches to management. This case study explores how agency/organizational characteristics and interrelations affect land management decision-making among land managers employed by federal agencies, state agencies, and non-governmental organizations. Semi-structured interviews were conducted with twenty-five participants, including land managers, staff members who maintain active participation with on-the-ground activities, and individuals who have worked closely with CRJVP. Triangulation of interview transcriptions, …

The View From The Table: An Analysis Of Participant Reactions To Community-Based Dialogues On Food And Justice, Jennifer Turner

Dissertations and Theses

While Portland, Oregon's sustainable food movement wins accolades for explicitly situating itself in opposition to the industrialized global food system, it often fails to address systems of oppression that are reproduced within the alternative agri-food movement itself. This demonstrated aversion towards the messy, complex, contingent nature of the social world reflects larger processes of "de-politicization" of the overall sustainability agenda, which leads to the favoring of technological and/or spatial solutions that may undermine the social equity and justice dimensions of the "triple bottom line." This thesis focuses on an action research project involving a series of community dialogues that provided …

The Role Of Gender In Scholarly Authorship, Jevin D. West, Jennifer Jacquet, Molly M. King, Shelley J. Correll, Carl T. Bergstrom

Sociology

Gender disparities appear to be decreasing in academia according to a number of metrics, such as grant funding, hiring, acceptance at scholarly journals, and productivity, and it might be tempting to think that gender inequity will soon be a problem of the past. However, a large-scale analysis based on over eight million papers across the natural sciences, social sciences, and humanities reveals a number of understated and persistent ways in which gender inequities remain. For instance, even where raw publication counts seem to be equal between genders, close inspection reveals that, in certain fields, men predominate in the prestigious first …

Elk (Cervus Elaphus) Seasonal Habitat Selection In A Heterogeneous Forest Structure, Jesse N. Popp, David N.C. Mcgeachy, Josef Hamr

Aspen Bibliography

Seasonal habitat selection by the reintroduced Burwash elk population, approximately 30 km south of Sudbury, Ontario, has been analysed in order to assist in the development of future management. Twenty-five adult females were radio-collared and tracked 1–3 times a week for 3 years. The most prominent patterns included selection of intolerant hardwood forests (trembling aspen, white birch, and balsam poplar) during all seasons, while Great Lakes-St. Lawrence pines (white and red pine dominated stands) were used less than expected based on availability for all seasons. The selection patterns are likely associated with seasonal climatic conditions and forage preferences. Because the …

Transient Simulation Of Orbital-Scale Precipitation Variation In Monsoonal East Asia And Arid Central Asia During The Last 150 Ka, Xinzhou Li, Xiaodong Liu, Linjing Qiu, Zhisheng An, Zhi-Yong Yin

Environmental and Ocean Sciences: Faculty Scholarship

A long-term transient simulation is conducted using the Community Climate System Model version 3 and the orbital acceleration technique to analyze the impact of insolation change caused by the Earth's orbital forcing on precipitation in the monsoonal East Asia (EA) and arid central Asia (CA) over the past 150 ka. Our results show that annual precipitation in both EA and CA has strong signals of the 20 ka precessional cycles and varies in phase with the Northern Hemisphere (NH) summer insolation. Similar characteristics can also be observed from previously published oxygen isotope records of stalagmites near EA and CA. Composite …

Physiological Mechanisms Of Shrub Encroachment: Linking Enhanced Hydraulic Capacity To Efficient Light Capture And Processing, Sheri Shiflett

Theses and Dissertations

Woody plant expansion has been documented for decades in many different ecosystems, often due to anthropogenic disturbances to the environment and yielding vast changes in ecosystem functioning. While causes and consequences of woody expansion have been well documented, few studies have investigated functional traits of woody species that promote rapid expansion in range. My objective was to determine if hydraulic efficiency confers enhanced photosynthetic efficiency so that functional traits representing light and water use may be possible mechanisms facilitating woody encroachment into grasslands and forest understories. I quantified leaf-level light environment, photosynthetic activity, and hydraulic characteristics of three sympatric broadleaf …

The Effect Of Geography And Personal Experience On Attitudes And Perceptions Of The Mexican Gray Wolf Reintroduction, Erin Marchand

Geography ETDs

This research examines the attitudes and perceptions of residents in Catron County and Harding County, New Mexico regarding the Mexican gray wolf reintroduction program under the Endangered Species Act. Catron County is within the wolf recovery zone and residents must deal with consequences of having wolves in the area. Harding County is located on the opposite side of the state and is removed from the wolf reintroduction area. Understanding the perceived concerns and benefits of the wolf reintroduction program and if those concerns change based on geographic proximity to the reintroduction can reveal whether cultural biases or personal experience with …

Non-Federal/Federal Collaborators In Endangered Species Driven River Restoration: How Risk And Incentive Mobilize Institutional Supply In The Middle Rio Grand Endangered Species Collaborative Program, Mark Lawler

Geography ETDs

The Middle Rio Grande Endangered Species Collaborative Program is an interagency, multiple-stakeholder organization, which works to enable cooperative solutions to endangered species issues on New Mexicos Middle Rio Grande. The Program is a product of what some authors describe as a 'new age' of environmental management. This study focuses on how local stakeholders interact with federal and state agencies within the Program to cooperatively invest in institutional changes to solve problems with tools of the 'new age' environmental management paradigm. It evaluates these tools in the context of pitfalls presented by dynamic interactions and an imbedded 'rule of law' regulatory …

Stochastic Dea With A Perfect Object And Its Application To Analysis Of Environmental Efficiency, Alexander Vaninsky

Publications and Research

The paper introduces stochastic DEA with a Perfect Object (SDEA PO). The Perfect Object (PO) is a virtual Decision Making Unit (DMU) that has the smallest inputs and greatest outputs. Including the PO in a collection of actual objects yields an explicit formula of the efficiency index. Given the distributions of DEA inputs and outputs, this formula allows us to derive the probability distribution of the efficiency score, to find its mathematical expectation, and to deliver common (group–related) and partial (object-related) efficiency components. We apply this approach to a prospective analysis of environmental efficiency of the major national and regional …

The Politics Of The "New North": Putting History And Geography At Stake In Arctic Futures, Andrew T. Stuhl

Faculty Journal Articles

References to a “New North” have snowballed across popular media in the past

10 years. By invoking the phrase, scientists, policy analysts, journalists and others

draw attention to the collision of global warming and global investment in

the Arctic today and project a variety of futures for the region and the planet.

While changes are apparent, the trope of a “New North” is not new. Discourses

that appraised unfamiliar situations at the top of the world have recurred

throughout the twentieth century. They have also accompanied attempts to

cajole, conquer, civilize, consume, conserve and capitalize upon the far north.

An Approximation Method To Calculate Complicated Expectations, Mohammad Moradi, Jennifer Brown

Journal of Statistics Applications & Probability

In some adaptive sampling designs, expectations need to be calculated as sampling progresses. For situations when these calculations need to be done in the field where there is no access to computers, or for very complicated and computer intensive calculations, we introduce an approximation method. The method to approximate the expectation is based on conditioning on small set of points. An application of the approximation method is described for a sample design with a complicated estimator.

Effectively Engaging Diasporas Under The New Canadian Department Of Foreign Affairs, Trade And Development, Manuelle Chanoine, Meredith Giel, Tâmara Simão

International Migration Research Centre

• With the amalgamation of the Canadian International Development Agency (CIDA) and the Department of Foreign Affairs and International Trade (DFAIT) into a new Department of Foreign Affairs, Trade and Development (DFATD), new opportunities will emerge for a coherent approach to diaspora engagement initiatives that combine the existing policy directions under a single umbrella.
• DFATD should work with diasporas in Canada to facilitate and improve engagement with the sending regions. This engagement can occur through current programs, as well as the creation of a new pilot project requiring cooperation between the different policy approaches.
• Engagement should vary according to the different …

Role Of Environment And Sex Differences In The Development Of Autoimmune Diseases: A Roundtable Meeting Project, Monica P. Mallampalli, Erika Davies, Debra Wood, Hillary Robinson, Federica Polato, Christine L. Carter

Prevention and Community Health Faculty Publications

Autoimmune diseases (ADs) impose substantial health and financial burdens in the United States and in many parts of the world. Women are disproportionately affected by many of these disorders, which often contribute to lifelong disabilities. While the number of patients with some ADs appears to be rising, the complexities of conducting epidemiological studies prevent a thorough understanding of the prevalence and incidence of these various conditions. Research on environmental influences of these illnesses is limited, although they are generally hypothesized to result from the interaction of environmental agents in genetically susceptible individuals. Further, there is little known regarding the role …

Minor Fitness Benefits For Edge Avoidance In Nesting Grassland Birds In The Northeastern United States, David G. Perkins, Noah G. Perlut, Allan M. Strong

Environmental Studies Faculty Publications

Grassland birds are often affected negatively by habitat fragmentation. Outcomes include greater nest predation and brood parasitism, decreased colonization rates of small, isolated patches, and greater nest density in remnant core habitats. These effects have been well documented in the Midwest, but little is known about fragmentation and edge effects on grassland birds in the fragmented agricultural fields within the forested landscapes of the northeastern United States. From 2002 to 2010, we assessed how edges and edge types affected nest-site location and daily nest survival (DNS) of Savannah Sparrows (Passerculus sandwichensis) and Bobolinks (Dolichonyx oryzivorus) breeding …
