The Effect Of Risk, Time Preference, And Poverty On The Impacts Of Forest Tenure Reform In China, Karen Anne Sullivan

Open Access Dissertations

Forest degradation has steadily increased throughout much of the world. The cause of this continued degradation is complex and multifaceted but there is a growing realization that a key cause, especially in developing countries, is insecure rights to ownership and use of forest resources. This realization coupled with a call for pro-poor forestry policy has stimulated the recent trend in forest policy toward strengthening property rights for forest resources by transferring property rights from the state to communities and individuals, giving them defined rights to manage and extract forest resources. However, a big puzzle remains unsolved—such reforms on property rights …

Community Engagement In Sustainable Design: A Case Study Of The Oberlin Project, Amanda L. Goldstein

Honors Papers

The Oberlin Project is an unprecedented opportunity for the city of Oberlin, Oberlin College, and other participating institutions to work together to achieve sustainable development and carbon neutrality. How might these institutions engage Oberlin citizens in some of the planning decisions that will shape Oberlin's future? Collaborating with citizens is important because in theory, encouraging participatory, collaborative planning contributes to just, equitable, and diverse cities. Study of sustainability initiatives in Chattanooga, Tennessee, for instance, reveal that it is possible for cities to make great leaps at sustainable urbanism while simultaneously building up a strong base of social capital aimed at …

Synthesis, Characterization, And Properties Of Homometallic Dinuclear Ruthenium Complex Containing Chloro-Phenanthroline And Bipyridine, A. A. Bhuiyan, S. Kudo

Journal of the Arkansas Academy of Science

This paper deals with the synthesis and spectroscopic investigation of homometallic dinuclear ruthenium(II) complex containing chlorophenanthroline and bipyridine ligands. This bimetallic ruthenium polypyridine complex may be useful for biological electron transfer studies. Heteroleptic ruthenium monomer complex Ru(bpy)2(Cl-phen) (where bpy = 2,2’-bipyridine and Cl-phen = 5-chloro- 1,10-phenanthroline) was prepared in a two step procedure previously developed in our laboratory. This monomer complex was used to prepare the ruthenium dimer complex, (bpy)2Ru(phen-phen)Ru(bpy)2, by utilizing the Ni-catalyzed coupling reaction. Both the complexes were purified by column chromatography. The identity and the integrity of the complexes were confirmed by elemental analysis as well as …

Determination And Assessment Of Potential Mobility Of Heavy Metals In Solid Samples By Sequential Extraction Procedures (Sep) / Keivan Nemati, Keivan Nemati

Student Works (2010-2019)

The use of sequential extraction schemes for fractionation of metals in different substrates has grown exponentially over the past two decades. Despite the popularity of these schemes, they have been criticized for metal redistribution and the reagents used. The work presented in this dissertation is aimed at addressing these problems by, (i) a Tessier sequential extraction (ii) a BCR sequential extraction schemes and modified BCR method, (iii) a comparison between Tessier and BCR method for shrimp aquaculture sludge. From the sequential extraction, Cd, Mn and Pb were mostly found in exchangeable/carbonate form, showed its susceptibility to be leached easily. Also …

Cultural Botany: Toward A Model Of Transdisciplinary, Embodied, And Poetic Research Into Plants, John C. Ryan

Research outputs 2011

Since the eighteenth century, the study of plants has reflected an increasingly mechanized and technological view of the natural world that divides the humanities and the natual sciences. In broad terms, this article proposes a context for research into flora through an interrogation of existing literature addressing a rapprochement between ways to knowledge. The natureculture dichotomy, and more specifically the plant-to-human sensory disjunction, follows a parallel course of resolution to the schism between objective (technical, scientific, reductionistic, visual) and subjective (emotive, artistic, relational, multi-sensory) forms of knowledge. The foundations of taxonomic botany, as well as the allied fields of environmental …

Microbial Community Analysis Of Lake Chillisquaque, A Small Water System In Central Pennsylvania, Allison Mayhew

Honors Theses

Cyanobacteria are photosynthetic organisms that require the absorption of light for the completion of photosynthesis. Cyanobacteria can use a variety of wavelengths of light within thevisible light spectrum in order to harvest energy for this process. Many species of cyanobacteria have light-harvesting proteins that specialize in the absorption of a small range of wavelengths oflight along the visual light spectrum; others can undergo complementary chromatic adaptation and alter these light-harvesting proteins in order to absorb the wavelengths of light that are mostavailable in a given environment. This variation in light-harvesting phenotype across cyanobacteria leads to the utilization of environmental niches …

A History Of Resilience Is A History Of Resistance, Melissa Ooten

Women, Gender and Sexuality Studies Faculty Publications

As an historian, I’m struck by the emphasis this documentary places on non-humans – be it animals, plants, soil, or mountains – although as a native of Appalachia, that doesn’t surprise me. The film is billed as “America’s first environmental history series: and as such, it gives us a bold, unique template of how to talk holistically about the concept of place and the specific place of Appalachia. While it may be particularly prescient to talk about the broader concept of place through ecology and other facets when analyzing the history of Appalachia, surely it is no less important when …

Estimating Industrial Building Energy Savings Using Inverse Simulation, Franc Server, J. Kelly Kissock, Dan Brown, Steve Mulqueen

Mechanical and Aerospace Engineering Faculty Publications

Estimating energy savings from retrofitting existing building systems is traditionally a time intensive process, accomplished by developing a detailed building simulation model, running the model with actual weather data, calibrating the model to actual energy use data, modifying the model to include the proposed changes, then running the base and proposed models with typical weather data to estimate typical energy savings. This paper describes a less time-intensive method of estimating energy savings in industrial buildings using actual monthly energy consumption and weather data. The method begins by developing a multivariate three-parameter changepoint regression model of facility energy use. Next, the …

"We Are The Owners": Autonomy And Natural Resources In Northeastern Nicaragua, Mary Finley-Brook

Geography and the Environment Faculty Publications

Although focused predominately on Miskitu politics, this chapter identifies various constraints to multi-ethnic self-determination, while noting barriers exist even among aid programs targeting political empowerment and community development. Nevertheless, I also explore examples of progress toward decentralization at regional and local levels regardless of an overall national context of political containment and economic exploitation.

The Environmental Impact Of The Retail Photoprocessing Industry In Santa Clara County: 1996 Vs. 2006, Benoit Delaveau

Master's Theses

Consumer digital cameras appeared on the market in 1994. Consequently, the photoprocessing industry experienced a downturn beginning in 2000, with a sudden drop in activity. This study focuses on the evolution of the retail photoprocessing industry between 1996 and 2006 and evaluates its four major environmental impacts: (1) energy use, (2) associated greenhouse gas emissions (GHG), (3) silver discharge, and (4) water consumption. The main method used for data analysis is based on the ISO 14040 standard for Life Cycle Assessment. The study utilizes data from: (a) impact quantification for two photoprocessing labs in Santa Clara County, and (b) a …

Dangerous Decor: Consumer Knowledge Of Health Risks Within Interior Spaces, Kaitlin Keith

Master's Theses

Interior décor is an ever-present part of people's daily lives. The furnishings and finishes with which people surround themselves are part of their personal expression, but these components in people's homes and work spaces can negatively affect their health. Products such as furniture and paints can contain harmful chemicals, including volatile organic compounds (VOCs) so toxic they are pollutants regulated by the U.S. Environmental Protection Agency. With the rise in the "green" movement, healthy and environmentally safe alternatives such as low or zero-VOC paints are becoming more available. This study assessed how aware consumers and design professionals are of environmentally …

Reducing Disturbances To Marine Mammals By Kayakers In The Monterey Bay, Megan Maye Gunvalson

Master's Theses

Team OCEAN is a kayaker-outreach program located in Monterey Bay National Marine Sanctuary under the direction of the National Oceanic and Atmospheric Administration, whose goal is to reduce disturbances to marine mammals by kayakers. This study documented the interactions between kayakers and resting harbor seals (Phoca vitulina) and southern sea otters (Enhydra lutris nereis) at Team OCEAN's two outreach sites, Cannery Row and Elkhorn Slough, to determine if outreach was effective in reducing disturbances to harbor seals and sea otters.

No difference was observed in the percentage of kayaks causing disturbances to resting harbor seals when comparing days Team OCEAN …

Post-Fire Analysis Of Sequoia Sempervirens Forests On The Central Coast Of California, Rachel Anne Lazzeri-Aerts

Master's Theses

The public perception of wildfire is that it destroys forests and that all fires should be quickly extinguished. However, fire plays a central role in determining structure, composition, and recruitment in many forest types. In coast redwood forests, the role of fire is not well understood, particularly in the southern part of the range. Observational data suggest that redwoods are relatively unaffected by fire. The sites of three 2008 and 2009 fires were sampled for this study: the Martin Fire in Bonny Doon, California, the Whitehurst Fire near Gilroy, California, and the Lockheed Fire near Swanton, California. Randomly selected ten-meter …

Optimizing Energy Savings From "Direct-Dc" In U.S. Residential Buildings, Evangelos Vossos

Master's Theses

An increasing number of energy-efficient appliances operate on direct current (DC) internally, offering the potential to use DC power from renewable energy systems directly and avoiding the losses inherent in converting power to alternating current (AC) and back. This paper investigates that potential for net-metered residences with on-site photovoltaics (PV) by modeling the net power draw of the "direct-DC house" with respect to today's typical configuration, assuming identical DC-internal loads. The power draws were modeled for houses in 14 U.S. cities using hourly simulated PV-system output and residential loads. The latter were adjusted to reflect a 35% load reduction representative …

Public Awareness About Global Warming In Hyderabad, India, Vani Sarraju Rao

Master's Theses

This study addressed public perceptions and awareness about global warming in India through a survey of 851 subjects in the city of Hyderabad in the year 2007. A stratified sample of nine segments of society showed that, although people consider global warming a serious problem, they do not clearly understand its causes, impacts, and solutions. The data analyses using paired T-tests indicated differences in levels of awareness about global warming, across age and education. ANOVA and regression analysis suggested that levels of awareness among respondents varied according to their occupation. The degree of seriousness with which subjects viewed global warming …

Developing Criteria And Metrics For Assessing Recycled Water Program Effectiveness, Michelle Arias

Master's Theses

Many U.S. states are currently experiencing or expect to experience water shortages in the next ten years. Recycling water is one strategy states are pursuing to minimize water shortages. Many states, however, have been unable to reach goals for volume of water recycled, and many regional and municipal programs have been ineffective in meeting production goals. Existing literature focuses primarily on how to implement a program and defines success as the ability to establish a program. After several decades of recycled water use in the United States, there is a lack of accepted metrics that allow for a cross comparison …

Riparian Wetland Response To Livestock Exclusion In The Lower Columbia River Basin, Sarah Ann Holmen

Dissertations and Theses

The purpose of this study was to examine the characteristics of riparian plant communities along a succession gradient of livestock exclusion in the Lower Columbia River Basin (LCRB). Livestock exclusion is an example of a passive restoration practice throughout the region. However, few studies have focused on the effects of livestock or livestock exclusion on riparian wetland ecosystems in this area. Two passive restoration sites, 3 and 13 years since livestock exclusion, and a control site with a continued livestock grazing presence were examined. It was hypothesized that native plant species richness would be lower in the excluded wetlands than …

Can Salmonids (Oncorhynchus Spp.) Be Identified To Species Using Vertebral Morphometrics?, Harriet R. Huber, Jeffery C. Jorgensen, Virginia L. Butler, Greg Baker, Rebecca Stevens

Anthropology Faculty Publications and Presentations

Remains of anadromous Pacific salmon and trout (genus Oncorhynchus) are common in archaeological sites from California to Alaska; however, morphological similarity generally precludes species identification, limiting the range of questions that salmonid remains can address in relation to past human use and ongoing efforts in conservation biology. We developed a relatively simple, rapid, and non-destructive way to classify salmon and trout vertebrae from archaeological contexts to species using length, height and the ratio of length to height. Modern reference material was obtained from all seven anadromous Oncorhynchus species native to the west coast of North America. A minimum of ten …

Analysis Of Three Types Of Sources To Determine The Existence Of Native Bees In Historical San Francisco, East Bay Area, Sharon Lee Ordeman

Master's Theses

The arrival of the missionaries in the late eighteenth century began the transformation of the San Francisco East Bay area from wetlands to orchards, grain fields, and grazing lands. This research considers the possibility that European and American newcomers enlarged native bee ranges in the East Bay cities of San Leandro, San Lorenzo, and Hayward when imported pollen and nectar-producing flora were planted. Three types of sources are analyzed: journals and diaries of explorers, missionaries, and botanists; native bee and plant specimens collected before the Gold Rush in 1848; and ethnographies of Ohlone Native Americans. Conclusive evidence for the presence …

Impact Of Embalming And Burial On Decomposition Rates And Diffusion Of Volatile Fatty Acids In Kentucky, Bonnie Charlana Mcquinn

LSU Master's Theses

Six still-born fetal pigs were divided into two groups (three were embalmed, and three non-embalmed) to determine a postmortem interval on decomposing remains in eastern Kentucky. One pig from each group was placed on the surface, one from each group was interred at a depth of two feet, and one from each group was buried at four feet. This study focused on observing necrophagous insect succession as well as how far on both a horizontal and a vertical plane volatile fatty acids leach from a body. Soil samples were taken from near all specimens at the time of respective termination …

Arctic Sea-Ice Melt In 2008 And The Role Of Solar Heating, Donald K. Perovich, Jacqueline A. Richter-Menge, Kathleen F. Jones, Bonnie Light

Dartmouth Scholarship

There has been a marked decline in the summer extent of Arctic sea ice over the past few decades. Data from autonomous ice mass-balance buoys can enhance our understanding of this decline. These buoys monitor changes in snow deposition and ablation, ice growth, and ice surface and bottom melt. Results from the summer of 2008 showed considerable large-scale spatial variability in the amount of surface and bottom melt. Small amounts of melting were observed north of Greenland, while melting in the southern Beaufort Sea was quite large. Comparison of net solar heat input to the ice and heat required for …

The Dirt On Prehispanic Water Management At Palmarejo, Honduras, Zaida Darley

USF Tampa Graduate Theses and Dissertations

Water is an essential resource for human life. Even in the tropical environment of the Maya Lowlands, water scarcity is a concern, because the region cycles between abundant rainfall and seasonal droughts. To understand how societies flourished during periods of water scarcity, archaeologists have studied prehispanic water management in the Maya Lowlands. Yet, water management research has tended to focus predominantly on large urban Maya populations, excluding smaller-scale societies that face the same challenges associated with water scarcity. This study investigates the neighboring non-Maya society of Late Classic (A.D.650-900) Palmarejo in northwestern Honduras to explore how water management was organized …
