Environmental Analysis Of Goes-R Proving Ground Convection Initiation Forecasting Algorithms, Jason M. Apke

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The enhanced temporal and spatial resolution of the GOES-R series will allow for the use of cloud top cooling based convection initiation (CI) forecasting algorithms. Two such algorithms have been created on the current generation of GOES satellites: theUniversityofWisconsincloud top cooling algorithm (UWCTC) and the University of Alabama-Huntsville’s satellite convection analysis and tracking algorithm (SATCAST). Preliminary analysis of algorithm products has led to speculation over pre-convective environmental effects on algorithm performance, which this study aims to examine. CI indications are used with objective segmentation tools to identify and cluster radar objects over theGreat Plainsbased on reflectivity quantitative and spatial thresholds. …

Methylmercury Fate In The Hypersaline Environment Of The Great Salt Lake: A Critical Review Of Current Knowledge, Danielle Barandiaran

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Methylmercury (MeHg) is a highly potent neurotoxic form of the environmental pollutant Mercury (Hg). The processes that are responsible for the conversion of Hg to MeHg are known to be both biotic and abiotic in freshwater systems. Although MeHg contamination is well documented in Great Salt Lake (GSL), the conversion of Hg into MeHg is not well-understood in saline environments much less in hypersaline waters such as GSL. The GSL is a broad, shallow high altitude (1280 m above sea level) lake that is exposed to large amounts of ultraviolet radiation and evaporation, which lead to great volatilization losses of …

The City In Mind: Environmental Literacy And Adaptation In Nineteenth-Century British Literature, Adam Edward Watkins

Open Access Dissertations

This dissertation argues that a new paradigm of selfhood emerged in nineteenth-century British literature, one that recognized the individual will and environmental influence not as antithetical but as dialectical forces in the formation of the self. The concept of an externally negotiated subject challenges both the inward and socially determined conceptions of self that have dominated the relevant criticism. Informed by empiricist, associationist, and evolutionary theories of the mind, the portrayals of subject-formation in this study highlight the radical changes occurring in the human environment in nineteenth-century, which catalyzed the conception of a malleable yet self-forming subject. Along with the …

Further Development Of A Model Of Environmental Commitment, Shane Boyd

Theses and Dissertations

Environmental commitment is a concept based on the investment model and interdependence theory literature. Interdependence theory and the investment model were originally geared towards the study of relationship commitment as function of relationship satisfaction and alternatives to being in that relationship. It has since been applied to areas outside of relationship commitment such as environmental commitment. Previous research has demonstrated that environmental commitment can be predictive of environmental behavior, above and beyond several different control variables that captured different aspects of the person-environment relationship (Davis, Le, & Coy, 2011; Davis, Green, & Reed, 2009). This project will strengthen the existing …

Engaging With The (Un)Familiar: Field Teaching In A Multi-Campus Teaching Environment, Nicholas Gill, Michael Adams, Christine Eriksen

Nicholas J Gill

Field trips have long been central to geography, but have been subject to assessment of the role of the 'field' in teaching. At the same time, academics face barriers to running field trips. Distance education and enhanced educational access for non-metropolitan students represented such an obstacle at an Australian university. These obstacles were taken as an opportunity to draw on the regional nature of the students and staff to enhance teaching goals, run critically informed field trips by and manage academic workloads. We evaluate the field trips by conducting surveys and interviews with students and tutors, and as an example …

Bird Mortality In The Human Built Environment, Stacie Schwartz

Honors Theses

Human development is having a detrimental effect on bird populations around the world. One hundred million to one billion birds are killed every year from colliding with human-built structures. I explored factors influencing the inability of birds to avoid man-made structures. If we can better understand these reasons, we can find solutions to this problem. After a known bird avoidance method, fritted glass, was installed in the Wold building, I investigated whether this glass actually deters birds from striking windows. Strikes on windows were noted daily through observation of specific windows on campus. Results show that vegetation outside of windows …

Energy Independence In The Usa, Janice Ringler

Student Papers in Public Policy

During President Barack Obama’s first term and throughout the recent presidential campaign, there was much discussion about becoming energy-independent as a nation. Indeed, one of the most pressing issues facing the country today is our energy future. This is especially a concern in areas where mainstream energy sources (coal, gas, oil) do not exist, and thus must be imported. Many believe that this is a problem that communities and states are better suited to tackle than the federal government due to the flexibility and knowledge of state policy initiatives. In this brief I will propose a variety of measures that …

The Consciousness Of Water: Narrative Flows, Environmental Change, And The Voice Of Yemen, Tricia Nellessen

Graduate Theses and Dissertations

Icebergs are melting in the Arctic. The Gulf of Mexico is warming and producing hurricanes such as Katrina. The delta of the southern United States is drying. And, Yemen will be the first country in modern history to experience a lack of accessible ground water, as soon as 2017 possibly. Yemen's situation has been tracked by scholars and governments since the 1960s. Despite this fact, cities have expanded in Yemen and the population has increased its use of water while little has been invested in desalination or infrastructure to offset growth. Climate change has affected humans for thousands of years; …

As teachers, writers, activists, and members of the progressive retirement community Pilgrim Place, they’ve had a significant influence on the global environmental movement. The photographs and small essays in this project highlight who they are and what they’ve done, and how they continue to shape contemporary intellectual discourse. An analysis of how portrait photographers use images to tell stories and how they incorporate text in their photographic collections to create fuller, more robust pictures …

Extending A Geographic Lens Towards Climate Justice, Part 1: Climate Change Characterization And Impacts, Morey Burnham, Claudia Radel, Zhao Ma, Ann Laudati

Environment and Society Faculty Publications

There has been a recent increase of interest within the academic literature on the justice issues posed by climate change and the human responses to its present and forecasted effects. This literature is partially shaped by debates from environmental justice scholarship, but also has roots in various subfields of geography. In two parts (here and in a subsequent article), we review and synthesize the recent literature by asking what climate justice concerns have been identified within three related realms: 1) the characterization of climate change itself and the assignment of responsibility for that change; 2) the differential or uneven impacts …

Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model And Stpa Tool, Karim Hardy, Franck Guarnieri

Publications

The goal of this article is dual: first, introducing a new model of accident named STAMP (systems-theoretic accident modeling and processes); then applying the model to an innovative process for the treatment of contaminated substances and the re-use of treated substances. This article is a demonstration for a need of a new tool to take into account hazards and safety within socio-technical systems.

Spatial Statistics In The Presence Of Location Error With An Application To Remote Sensing Of The Environment, Noel A. Cressie, John Kornak

Professor Noel Cressie

Techniques for the analysis of spatial data have, to date, tended to ignore any effect caused by error in specifying the spatial locations at which measurements are recorded. This paper reviews the methods for adjusting spatial inference in the presence of data-location error, particularly for data that. have a continuous spatial index (geostatistical data). New kriging equations are developed and evaluated based on a simulation experiment. They are also applied to remote-sensing data from the Total Ozone Mapping Spectrometer instrument on the Nimbus-7 satellite, where the location error is caused by assignment of the data to their nearest grid-cell centers. …

Becoming Multiliterate: Digital Video News Construction Within A Technology-Supported Learning Environment, Lori Lockyer, Ian M. Brown, David Blackall, Barry M. Harper, Phillip J. Mckerrow

David Blackall

Twenty-first century literacies imply multiliteracies – going beyond language literacy and numeracy to, among others, information, visual, media and technological literacies. An education that develops capabilities across a range of literacies equips young people with the skills necessary to participate in a complex, globalized workplace and community. A key step toward realizing such national and state education agendas is specific curriculum interventions that are translated to the classroom level. This paper reports on a case study that explored both the process and outcomes of the implementation of an education program which was designed to incorporate multiliteracies.

A Profile Of Travelers Who Are Willing To Stay In Environmentally Friendly Hotel, Michelle Millar, Karl J. Mayer

Hospitality Review

The purpose of this study is to describe travelers that have indicated they are willing to stay in green hotel in order to better understand the market segment. There is very little knowledge about these types of travelers, thus making it difficult for hoteliers to know how to create marketing campaigns that target them. Data were collected via an online survey company. Behavior characteristics provided a more distinguishing profile of the traveler than did demographics or psychographics. Most travelers were willing to pay the same amount for a green hotel as a traditional hotel. Implications, future research, and limitations are …

Mapping Light Pollution At Utah State University, Rachel K. Nydegger, Shane L. Larson Ph.D.

Rachel Nydegger Rozum

One of the beauties of modern civilization is seeing the city lighting at night. It provides a feeling of security and is indicative of the power and endeavors of humanity, but over-lighting is a form of pollution. Many outdoor light fixtures spread light in all directions, sending a majority of the light into the sky, away from where we want the light to be on the ground. This light spreading upward is not only wasted light, but it is wasted energy and money, destroys our ability to view the night sky, and has profound effects on nocturnal creatures. The direct …

Leadership Development For Pro-Environmental Behavior Utilizing Peer To Peer Communication And Learning: An Academic Pilot Project, Mark Wayne Carrera Ma

All Student Scholarship

There is a cultural perception that the onus of responsibility for shark conservation falls on the shoulders of environmental and scientific communities’ leaders. Given the diminutive size of these two communities when compared to the vastness of American society, responsibilities should be shared by leaders of educational organizations who can communicate with greater populations. The general public must be encouraged to act pro-environmentally for effective shark conservation to ever take place in the world.

Dinosolve: A Protein Disulfide Bonding Prediction Server Using Context-Based Features To Enhance Prediction Accuracy, Ashraf Yaseen, Yaohang Li

Computer Science Faculty Publications

Background: Disulfide bonds play an important role in protein folding and structure stability. Accurately predicting disulfide bonds from protein sequences is important for modeling the structural and functional characteristics of many proteins.

Methods: In this work, we introduce an approach of enhancing disulfide bonding prediction accuracy by taking advantage of context-based features. We firstly derive the first-order and second-order mean-force potentials according to the amino acid environment around the cysteine residues from large number of cysteine samples. The mean-force potentials are integrated as context-based scores to estimate the favorability of a cysteine residue in disulfide bonding state as well as …

The Feasibility Of Using Vanadium And Nickel To Track Oil Spills In Coastal Environments, Sean Patrick Kenny

LSU Master's Theses

Crude oil has been increasing in world demand over the past century. It is known that oil is resistant to weathering processes and if spilled, can cause serious environmental damage to an area, on land or sea. A complementary approach to current methods of tracking oil and identifying spill-impacted sediments may be to measure trace metals associated with crude oil. Trace metals, such a vanadium (V) and nickel (Ni) are known to be elevated in concentration in some oil sources, but little work has been done on this topic. This research explored less expensive and time-consuming methods to track or …
