Turkish Journal of Chemistry

The aim of this study was to determine natural radioactive and heavy element concentrations in Mersin drinking water samples before the commissioning of the Akkuyu nuclear power plant and to collect data for possible environmental contaminations in the future. Drinking water samples were taken from the provincial center, districts, and populated villages. The annual effective dose of natural radionuclides and cancer risks were calculated for each person living in the city. Hazard index and cancer risk were calculated, which were caused by heavy elements. Mean gross alpha and beta radioactivity concentrations in drinking water were 0.059 Bq/L and 0.120 Bq/L, …

An Independent Review Of Forest Practices In Nova Scotia: Executive Summary Conclusions And Recommendations, William Lahey Prof.

Reports & Public Policy Documents

My mandate was to make recommendations on forest practices that would, if implemented, balance environmental, social, and economic objectives, which I have interpreted to include values. My conclusion is that environmental, social, and economic values should be balanced by using forest practices that give priority to protecting and enhancing ecosystems and biodiversity.

In other words, I have concluded that protecting ecosystems and biodiversity should not be balanced against other objectives and values as if they were of equal weight or importance to those other objectives or values. Instead, protecting and enhancing ecosystems should be the objective (the outcome) of how …

Administrative Guidance And Genetically Modified Food, Edward L. Rubin, Joanna K. Sax

Faculty Scholarship

One of the most controversial issues in administrative law, the use of guidance, is exemplified by the regulation of one of the most controversial areas in modern society: genetically modified (GM) food. The appropriate use of guidance versus notice and comment rulemaking is a much-debated issue in administrative law. While agency officials generally assert that they are using guidance to express an agency’s thoughts about how to comply with a specific statutory provision or agency rule, the practical consequence is that the regulated party will hesitate to disobey, even if it believes that the guidance goes beyond the requirements of …

Environmental Law—How It Got There Matters: Trail Smelter Evades Cercla Responsibility For The Aerial Deposition Of Hazardous Waste, Ryan K. Sullivan

Western New England Law Review

The Trail Smelter, operated by Teck Cominco Metals, Ltd., is an integrated smelting and refining complex in Trail, British Columbia. It is situated approximately ten miles north of the United States-Canadian border. In the early 1900s, the smelter was at the center of an international lawsuit that led to a landmark decision of international environmental law. Now, almost a century later, the smelter, still in operation, is responsible for widespread contamination on tribal lands located within Washington State. Once again, the smelter is embroiled in a protracted legal battle, this time facing liability under the Comprehensive Environmental Response, Compensation, and …

Laudato Si' - Establishing Local Approaches For Global Ecological Conversion, Anne Jennings

Arts Papers and Journal Articles

In 2017 the Aotearoa Community Development Association (ACDA) and the International Association for Community Development (IACD) held a conference, Sustainably yours: Community development and a sustainably just future, in Auckland where I presented a paper titled “Community development – The ‘missing ingredient’ in striving for sustainability”. That paper examined the United Nations Agenda 2030 (2015) and, in particular, the associated Sustainable Development Goals (SDGs).

This paper will explore a further significant document, also released in 2015, the encyclical (letter) by Pope Francis, Laudato si’: On care for our common home. The paper starts with some history of the Pope’s work, …

Machine-Learning-Based Quantitative Estimation Of Soil Organic Carbon Content By Vis/Nir Spectroscopy, Jianli Ding, Aixia Yang, Jingzhe Wang, Vasit Sagan, Danlin Yu

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Soil organic carbon (SOC) is an important soil property that has profound impact on soil quality and plant growth. With 140 soil samples collected from Ebinur Lake Wetland National Nature Reserve, Xinjiang Uyghur Autonomous Region of China, this research evaluated the feasibility of visible/near infrared (VIS/NIR) spectroscopy data (350-2,500 nm) and simulated EO-1 Hyperion data to estimate SOC in arid wetland regions. Three machine learning algorithms including Ant Colony Optimization-interval Partial Least Squares (ACO-iPLS), Recursive Feature Elimination-Support Vector Machine (RF-SVM), and Random Forest (RF) were employed to select spectral features and further estimate SOC. Results indicated that the feature wavelengths …

Environmental Forensics Study Of Crude Oil And Petroleum Product Spills In Coastal And Oilfield Settings: Combined Insights From Conventional Gc-Ms, Thermodesorption-Gc-Ms And Pyrolysis-Gc-Ms, Michael A. Kruge, José Luis Gallego, Azucena Lara-Gonzalo, Noemi Esquinas

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

A representative set of five oil spill samples from four different regions displayed different product characteristics and different levels of weathering. Three of them were taken along shorelines affected by marine oil spill events, viz., Aboño and Prestige (Spain) and Deepwater Horizon (USA) and the other two were taken at inland oil spill sites (Angola and Kuwait). A multi-faceted environmental forensics approach revealed key molecular features. In addition to the conventional GC/MS analysis of saturated and aromatic fractions, the polar fractions also were analyzed, revealing a complex series of linear alkanones in those oil samples particularly enriched in aliphatics. Thermodesorption-GC-MS …

A Western Interconnection Regional System Operator: Benefits And Barriers, Siena Hacker

Scripps Senior Theses

A Regional System Operator in the Western Interconnection would create significant environmental and economic benefits. California alone could realize annual savings of up to 1.5 billion dollars while cutting the state’s greenhouse gas emissions by eight to ten percent in 2030. However, many stakeholders have rejected development of a Regional System Operator both historically and in recent California Legislative sessions. Ultimately, key stakeholders’ fears of repeating the California Electricity Crisis, relinquishing state authority, allowing greater interference from the Federal Energy Regulatory Commission, and sacrificing legislative environmental progress in California have created political opposition and legislative failures blocking efforts to develop …

Mortgage Finance Market And Housing Affordability In Urban Areas In Rwanda: A Case Of Kigali City, Samuel Iyandemye, Jonas Barayandema, Faustin Gasheja

Journal for the Advancement of Developing Economies

Rapid urbanization in Rwanda has considerably increased housing demand and the need for a dependable mortgage market. Unfortunately, the capacity of most people to afford to own homes from their own incomes is still a challenge as mortgages products are available at outrageous conditions making mortgage finance unaffordable. For better market readjustment, the effects or mortgage market factors on housing affordability in any locality should be properly evaluated. The objective of this study is to determine how mortgage finance market affects the affordability of housing in Kigali, the capital city of Rwanda. To attain this objective, data was obtained from …

From Bison To Cattle: The Ecology Of The Southern Plains 1500-1750, Jenni Tifft-Ochoa

Calvert Undergraduate Research Awards

Bison made their home on the Southern Plains for millennia. However, their migratory patterns began to shift in the 17^th and 18^th centuries. My research investigated what caused this drastic shift and how it had far reaching effects on the ecology of the Southern Plains. Using archives from two prominent Catholic priests, I began to piece together why the bison left the Southern Plains. Rather than focus on the Europeans as the main players, I instead focused on the Indigenous peoples, the animals, and the land as the centralized actors in this project. I discovered that the introduction …

Honors In Chile: New Engagements In The Higher Education System, Juan Carlos Skewes, Carlos Alberto Cioce Sampaio, Frederick J. Conway

Honors in Practice Online Archive

Honors programs are rare in Latin America, and in Chile they were unknown before 2003. At the Universidad Austral de Chile, an interdisciplinary group of scholars linked to environmental studies put forward a pilot project for implementing a new experience in higher education. Challenged by an educational environment where (i) apathy and mediocrity have taken over the classrooms, (ii) monodisciplinary training rules the university campus, and (iii) authoritarian teaching persists, this has been an experiment in new ways of approaching the classroom. Stimulated by experiences in the USA, a project proposal was written, finding support in the Chilean Ministry of …

“In Landlessness Alone Resides The Highest Truth”; Or, At Sea With Honors, Don Dingledine

Honors in Practice Online Archive

The recent explosion on an oil rig in the Gulf of Mexico was a grim reminder of the BP disaster in 2010, from which Gulf Coast residents and workers are still trying to recover. We all must have responded to that disaster with a similar sense of outrage as we watched the live underwater video feed of millions of gallons of oil spewing into the ocean and saw images of oil-soaked wildlife, coastlines, and marshlands. Shared memories of Hurricane Katrina heighten our collective sympathy for the people whose livelihoods this disaster still threatens. At the same time, our individual responses …

Determining Potential Uptake Pathways Of Persistent Organic Pollutants And Heavy Metals In Jobos Bay National Estuarine Research Reserve, Puerto Rico, Ashley Huber

USF St. Petersburg campus Master's Theses (Graduate)

Fiddler Crab (U. rapax) tissue, mangrove tissue and sediment from crab burrows were collected in Jobos Bay National Estuarine Research Reserve, Puerto Rico, to quantitate Persistent Organic Pollutants (OCs, PCBs, PBDEs) and selected heavy metals (cadmium, barium, mercury, lead, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic and selenium). Once quantified, the concentrations were applied to a bioconcentration factor equation to determine potential uptake pathways of the target analytes. Bioconcentration factors determined that fiddler crabs were the most efficient at concentrating OC pesticides, while mangroves were the most efficient at concentrating PCBs and heavy metals.

Impacts Of 40 Years Of Land Cover Change On Water Quality In Tampa Bay, Florida, Matthew J. Mccarthy, Frank E. Muller-Karger, Daniel Otis, Pablo Méndez-Lázaro

Marine Science Faculty Publications

Land cover changes in the Tampa Bay watershed (Florida) over the past four decades were examined along with precipitation and wind observations to help understand causes of long-term changes in turbidity and chlorophyll concentration within the Tampa Bay estuary. Water quality showed a statistically significant relationship to land cover fraction in the watershed compared to long-term precipitation or wind stress. Redundancy Analyses with Akaike’s Information Criterion and non-parametric multiple regressions determined that turbidity and chlorophyll concentration decreased bay-wide from 1974–2012 with increased developed land fraction (R2 > 0.75, p-value < 0.05). Various segments of the estuary showed different significant responses to developed land (R2 > 0.75, p-value < 0.05), agricultural land (R2 > 0.93, p-value < 0.02), bare land (R2 = 0.77, p-value = 0.001), and wind stress (R2 = 0.91, p-value = 0.04) at different times of year.

Stormwater Capture In The Built Watershed: Fostering Public Awareness Of Water Conservation Through A Parcel-Level Approach To Stormwater Management, Benjamin Rigby

Pitzer Senior Theses

As California contends with climate change and more extreme cycles of drought and deluge, water management agencies and conservation groups are looking towards solutions to the decreasing reliability of imported water supplies. Stormwater has historically been perceived as a threat to development but when captured properly, it presents a resource that can augment local water supplies. Solutions to water supply issues in California have traditionally employed technical and centrally controlled methods for importing water, but there is a growing understanding that parcel-level capture through vegetated swales presents an opportunity for reducing the impact that development has on California’s hydrology. Vegetated …

“It’S Not Easy Being Green”: Predictors Of Pro-Environmental Behaviors Among College Students, Morgan Laner

Honors Program Theses

This study looks at the different predictors of the pro-environmental behaviors of undergraduate college students at a small, urban, private liberal arts college in Florida. A total of 437 students reported their environmental attitudes, subjective norms, intentions, perceived behavioral control, and pro-environmental behaviors. Results shows that the sample population replicates the relationships of the theory of planned behavior framework. Attitudes were the strongest predictors of intentions, which in turn had a positive, moderately strong relationship with pro-environmental behavior. Men were found to have higher means for intentions and attitudes than women. Understanding the perceptions and behaviors of students can help …

Morphology, Taxonomy And Mating‑Type Loci In Natural Populations Of Volvox Carteri In Taiwan, Hisayoshi Nozaki, Noriko Ueki, Mari Takusagawa, Shota Yamashita, Osami Misumi, Ryo Matsuzaki, Masanobu Kawachi, Yin-Ru Chiang, Jiunn-Tzong Wu

Publications and Research

Background: Volvox carteri f. nagariensis is a model taxon that has been studied extensively at the cellular and molecular level. The most distinctive morphological attribute of V. carteri f. nagariensis within V. carteri is the production of sexual male spheroids with only a 1:1 ratio of somatic cells to sperm packets or androgonidia (sperm packet initials). However, the morphology of male spheroids of V. carteri f. nagariensis has been examined only in Japanese strains. In addition, V. carteri f. nagariensis has heterothallic sexuality; male and female sexes are determined by the sex-determining chromosomal region or mating-type locus composed of a …

Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter

Ecology, Evolution, and Behavior

Information, energy, and materials are flowing over greater distances than in the past, changing the structure and feedbacks within and across coupled human and natural systems worldwide. The telecoupling framework was recently developed to understand the feedbacks and multidirectional flows characterizing social and environmental interactions between distant systems. We extend the application of the telecoupling framework to illustrate how flows in beef affect and are affected by social-ecological processes occurring between distant systems in Africa, and how those dynamics will likely change over the next few decades because of climate-induced shifts in a major bovine disease, trypanosomosis. The disease is …

Conceptual Framework For A Curriculum In Social Change, Iris M. Yob

Walden Faculty and Staff Publications

Colleges, universities, and many high schools are expressing their mission in terms of creating social change or contributing to the common good. Such a mission suggests that if they are going to graduate students who will fulfill this mission, they will need to consider how they will best prepare students to do this. The conceptual framework for a curriculum in social change in this article offers a holistic approach, taking into account what a student should know, be able to do, and what values and attitudes should be nurtured. To that end, the article identifies three competencies in the knowledge …
