A New Technique For Modeling The Geomorphology Of A Slow Moving, Soft-Slope Landslide Using Terrestrial Lidar, Nathan Bradley Rohrbaugh

Masters Theses

"Soft slope movement is a big problem whether it involves an engineered slope, one that is near infrastructure, or both. Active landslides that fail slowly sometimes allow ample time to affect remedial works. In order to plan effective remedial works, there needs to be a model of the entire geometry of the slide. This thesis describes a new approach to evaluate the morphology of slope geometry using Light Detection and Ranging (LiDAR) data obtained from simple targets strategically positioned on a slide body. The data was gathered in three-month intervals over a period of one year to allow enough time …

Characteristics Of Social Media Stories, Yasmin Ainoamany, Michele C. Weigle, Michael L. Nelson

Computer Science Faculty Publications

An emerging trend in social media is for users to create and publish "stories", or curated lists of web resources with the purpose of creating a particular narrative of interest to the user. While some stories on the web are automatically generated, such as Facebook’s "Year in Review", one of the most popular storytelling services is "Storify", which provides users with curation tools to select, arrange, and annotate stories with content from social media and the web at large. We would like to use tools like Storify to present automatically created summaries of archival collections. To support automatic story creation, …

A Composite Spatial Model Incorporating Groundwater Vulnerability And Environmental Disturbance To Guide Land Management, Johanna L. Kovarik

USF Tampa Graduate Theses and Dissertations

Research has long recognized and studied the dynamics of groundwater processes. More recently, groundwater dependent ecosystems (GDEs) are being recognized for their diversity and vulnerability to anthropogenic impact. Groundwater in karst landscapes presents a distinctive situation where flow through the subsurface often moves rapidly on the scale of days and weeks as opposed to years or millennia in other systems. This distinctive situation of karst systems and their vulnerability to human impacts necessitate an integrated and multifaceted approach for the management of these important resources. However, development of such an approach is complicated by the difficulty of obtaining detailed data …

Glaciological Applications Of Terrestrial Radar Interferometry, Denis Voytenko

USF Tampa Graduate Theses and Dissertations

Terrestrial Radar Interferometry (TRI) is a relatively new ground-based technique that combines the precision and spatial resolution of satellite interferometry with the temporal resolution of GPS. Although TRI has been applied to a variety of fields including bridge and landslide monitoring, it is ideal for studies of the highly-dynamic terminal zones of marine-terminating glaciers, some of which are known to have variable velocities related to calving and/or ocean-forced melting. My TRI instrument is the Gamma Portable Radar Interferometer, which operates at 17.2 GHz (1.74 cm wavelength), has two receiving antennas for DEM (digital elevation model) generation, and images the scenes …

The Action Cycle/Structural Context Framework: A Fisheries Application, D. G. Webster

Dartmouth Scholarship

There is a growing consensus that environmental governance is a wicked problem that requires understanding of the many linkages and feedbacks between human and natural systems. Here, I propose an action cycle/structural context (AC/SC) framework that is based on the concept of responsive governance, in which individuals and decision makers respond to problems rather than working to prevent them. By linking agency and structure, the AC/SC framework points out two key problems in the realm of environmental governance: the profit disconnect, whereby economic signals of environmental harm are dampened by endogenous or exogenous forces, and the power disconnect, whereby those …

This study explores the potential risks associated with the 65 U.S.-based commercial nuclear power plants and the distribution of those risks among the populations of both their respective host communities and of the communities located in outlying areas. First, it starts by examining the racial/ethnic composition of the host community populations, as well as the disparities in socioeconomic status that exist, if any, between the host communities and communities located in outlying areas. Second, it utilizes two independent-sample T tests to identify any differences in the sociodemographic compositions of the two areas. Third, it explores regional demographic trends by looking …

Sparse Coding Based Dense Feature Representation Model For Hyperspectral Image Classification, Ender Oguslu, Guoqing Zhou, Zezhong Zheng, Khan Iftekharuddin, Jiang Li

Electrical & Computer Engineering Faculty Publications

We present a sparse coding based dense feature representation model (a preliminary version of the paper was presented at the SPIE Remote Sensing Conference, Dresden, Germany, 2013) for hyperspectral image (HSI) classification. The proposed method learns a new representation for each pixel in HSI through the following four steps: sub-band construction, dictionary learning, encoding, and feature selection. The new representation usually has a very high dimensionality requiring a large amount of computational resources. We applied the l₁/l_q regularized multiclass logistic regression technique to reduce the size of the new representation. We integrated the method with a linear …

Exploring How Social Media Can Be Used To Promote Space Awareness: A Case Study Of The Yuri's Night Web 2.0, Alan Steinberg, Jeffrey Alles, Ryan L. Kobrick

Publications

Despite the importance of social media as an inexpensive and efficient means of communication, it is not clear to what degree space advocacy groups are making a strong organized effort to use the resources available to them. Moreover, there is no previous literature that specifically examines the use of social media tools by space organizations. This study seeks to start a larger dialog regarding how the space advocacy community can make use of these tools to promote their mission. Using a case study approach, this article focuses specifically on the organization of Yuri’s Night to explore how this group is …

Participatory Conservation Of Coastal Habitats: The Importance Of Understanding Homeowner Decision Making To Mitigate Cascading Shoreline Degradation, Steven B. Scyphers, Steven J. Picou, Sean P. Powers

University Faculty and Staff Publications

Along densely populated coasts, the armoring of shorelines is a prevalent cause of natural habitat loss and degradation. This article explores the values and decision making of waterfront homeowners and identifies two interlinked and potentially reversible drivers of coastal degradation. We discovered that: (1) misperceptions regarding the environmental impacts and cost-effectiveness of different shoreline conditions was common and may promote armoring; and (2) many homeowners reported only altering their shorelines in response to damage caused by armoring on neighboring properties. Collectively, these findings suggest that a single homeowner’s decision may trigger cascading degradation along a shoreline, which highlights the necessity …

Metadata And Linked Data In Word Sense Disambiguation, Matthew Corsmeier

Library Philosophy and Practice (e-journal)

Word Sense Disambiguation (WSD) can be assisted by taking advantage of the metadata embedded in the various ontologies, lexica, databases, etc… that exist in the Semantic Web. Automated processes that exploit the links already present in the Semantic Web can strengthen parsing of word senses by using user-contributed and semantically-linked data. These processes are only possible because of a commitment to interoperability and the creation of shared standards. This paper will review some of the most heavily used Linguistic Linked Open Data (LLOD) tools and models which show the most promise for using metadata to alleviate problems caused by polysemous …

Human Behavior During Spaceflight - Evidence From An Analog Environment, Kenny M. Arnaldi, Guy Smith, Jennifer E. Thropp

Journal of Aviation/Aerospace Education & Research

Spaceflight offers a multitude of stressors to humans living and working in space, originating from the external space environment and the life-support system. Future space participants may be ordinary people with different medical and psychosocial backgrounds who may not receive the intense spaceflight preparation of astronauts. Consequently, during a mission, a space participant’s mood and behavior could differ from a trained astronaut. This study was an exploratory research project that used an artificial habitat to replicate an orbital environment and the activities performed by humans in space. The study evaluated whether the type of environment affects mood and temperament. Two …

Enhancing Workplace Productivity And Competitiveness In Trinidad And Tobago Through Ict Adoption, Kennedy Jerome Swaratsingh

Walden Dissertations and Doctoral Studies

The productivity of Trinidad and Tobago's public sector workplaces is related to their absorptive capacity for technological adoption. Guided by the technology acceptance model, which suggests that individuals' and institutions' use of technology increases in relation to perceived ease of use and apparent value, this case study explored how Trinidad and Tobago used information and communications technology from 2001 - 2010 to improve public sector workplace productivity. Study data were collected from 22 individual interviews with senior executives from the government of Trinidad and Tobago, members of the e-business roundtable, and local industry experts, and from reviewing the archives of …

Boundaries Of Governance: Social Responsibility In Mining In Western Australia, Gemma L. Broderick

Theses: Doctorates and Masters

This research investigated the boundaries of governance of social responsibility in three multinational mining organisations based in Perth, Western Australia. The mining industry has economic, environmental and social impacts, both positive and negative. While most of the attention of the media and supporters in government seems to focus on the positive impacts, a growing concern regarding the social implications of mining is clearly evident in public discourse and the academic literature. In response to public concern, the mining industry has adopted terms such as ‘sustainability’, ‘sustainable development’, ‘social licence to operate’ and ‘social responsibility’. Such phrases are widely used in …

An Appraisal Of Experiences Of Climate Change And Adaptive Response To Heat Stress By Farmers In Rural Ghana, Kwasi Frimpong

Theses: Doctorates and Masters

With the increase in average global temperatures, heat-related illnesses and deaths have unfolded as occupational and health issues. Periods of high to extreme temperatures are becoming more common and are a leading cause of weather-related deaths in many countries. In agricultural settings of African countries, heat stress is a major concern as many smallholder farmers work outdoors with limited access to cooling systems even in their resting and living environments. This study, conducted in the Bawku East part of Northern-East Ghana in 2013, examines, in the context of climate change, the trends and impacts of heat stress on smallholder farmers, …

Intensity Based Interrogation Of Optical Fibre Sensors For Industrial Automation And Intrusion Detection Systems, Gary Andrew Allwood

Theses: Doctorates and Masters

In this study, the use of optical fibre sensors for intrusion detection and industrial automation systems has been demonstrated, with a particular focus on low cost, intensity-based, interrogation techniques. The use of optical fibre sensors for intrusion detection systems to secure residential, commercial, and industrial premises against potential security breaches has been extensively reviewed in this thesis. Fibre Bragg grating (FBG) sensing is one form of optical fibre sensing that has been underutilised in applications such as in-ground, in-fence, and window and door monitoring, and addressing that opportunity has been a major goal of this thesis. Both security and industrial …

Judging Dread: A Quantitative Investigation Of Affect, Psychometric Dread And Risk Consequence, Melvyn Griffiths

Theses: Doctorates and Masters

Risk is generally understood as a product of the likelihood and consequence of an event. However, the way in which estimations of consequences are formed is unclear due to the complexities of human perception. In particular, the influence of Affect, defined as positive or negative qualities subjectively assigned to stimuli, may skew risk consequence judgements. Thus a clearer understanding of the role of Affect in risk consequence estimations has significant implications for risk management, risk communication and policy formulation.

In the Psychometric tradition of risk perception, Affect has become almost synonymous with the concept of Dread, despite Dread being measured …

Evaluating Success Factors In Implementing E-Maintenance In Maintenance, Repair, And Overhaul (Mro) Organizations, Peter Rocky Toves

Walden Dissertations and Doctoral Studies

Despite more than a decade-long process to transition aircraft maintenance practices from paper-to electronic-based systems, some organizations remain unable to complete this transition. Researchers have indicated that while organizations have invested resources in technology improvements, there remains a limited understanding of the factors that contribute to effectively managing technology-enabled change. The purpose of this case study was to identify and explore socio-technical (ST) factors that inhibit an effective transition from a paper-based system to an electronic-based system for aircraft maintenance. A conceptual model applying theories of change management, technology acceptance, systems thinking, and ST theory informed the research. Thirteen participants …

Communication Constructs That Influence Information Technology Project Failure, Vanessa Lajuan Ruth Mackey

Walden Dissertations and Doctoral Studies

Ineffective communication behavioral constructs in the workplace that lead to information technology (IT) project failure and in some cases organization failure are increasingly becoming a management concern. Despite this trend, there is little research on the communication behavioral constructs that contribute to IT project failure rates. The purpose of this phenomenological study was to explore the lived experiences of business analysts, programmers, and programmer analysts pertaining to the behavioral constructs associated with effective and ineffective communication. The research questions addressed these behaviors from a conceptual framework based on communication theory, organizational information processing theory, and critical social theory. This framework …

Regression Analysis Of Cloud Computing Adoption For U.S. Hospitals, Terence H. Lee

Walden Dissertations and Doctoral Studies

Industrial experts agree that cloud computing can significantly improve business and public access to low cost computing power and storage. Despite the benefits of cloud computing, recent research surveys indicated that its adoption in U.S. hospitals is slower than expected. The purpose of this study was to understand what factors influence cloud adoption in U.S. hospitals. The theoretical foundation of the research was the diffusion of innovations and technology-organization-environment framework. The research question was to examine the predictability of cloud computing adoption for U.S. hospitals as a function of 6 influential factors: relative advantage, compatibility, complexity, organizational size, structure, and …

The study specifically examined the experiences of these men in their efforts to access health care treatment, housing, education, and employment in Central Pennsylvania. An empirical, phenomenological research design was employed that used self-stigma, critical race, and self-determination theories for in-depth interviews with 8 men who spent 5 to 24 years in prison. A tiered coding method was used to generate 6 interconnected themes that tell the story of these men's lives: …

Engaging The Nonprofits In Louisville Housing Market For Low-Income Households, Joshua Omoniyi Odetunde

Walden Dissertations and Doctoral Studies

Nonprofit organizations often work in partnership with government agencies to empower low income people in the housing market through government subsidized mortgage loans. In spite of this assistance, homelessness and substandard housing is pervasive among low income households because this population primarily relies on the rental housing market, leaving a gap in practice and knowledge related to how nonprofits provide assistance to the overwhelming majority of low income consumers in need of housing. The purpose of this case study was to use social justice theory to explore how the nonprofit sector, as an economic force, provides assistance to and empowers …

Animas-La Plata Project Stakeholder Narratives: A Case Study Using Kingdon's Three Streams Theory, Denise Renee Rue-Pastin

Walden Dissertations and Doctoral Studies

Population growth, coupled with changing weather patterns, is straining water supplies, especially in the American Southwest. A multitude of tools, including additional storage, will be needed to meet water demand and supply gaps. The Animas-La Plata Project, a reservoir in southwest Colorado, provides a case study of how groups worked for nearly 70 years to solve a water problem: insufficient irrigation for agriculture. This qualitative case study addressed a lack of first-person narratives from those most involved. Its purpose was to gather stakeholder narratives and analyze them using Kingdon's three streams theory to address the extent to which the problem, …

County Demographic Influence On Toxic Chemical Activities Of Chemical-Related Industry In Michigan, Lisa Helen Perricane

Walden Dissertations and Doctoral Studies

There are a large number of chemical facilities that emit toxic chemicals in Michigan, and there is a concern regarding toxic chemical exposure to the residents of Michigan counties. However, it is uncertain whether chemical companies that emit toxic chemicals in Michigan are influenced by county demographic factors in deciding whether to engage in voluntary pollution prevention (P2) activities and whether this decision influences U.S. Environmental Protection Agency's (U.S. EPA) Risk-Screening Environmental Indicators (RSEI) scores. Using Bullard's theory of environmental justice, the purpose of this quantitative study was to determine if there was a correlation between chemical-related industry's voluntary P2 …

Information Operations Under International Law: A Delphi Study Into The Legal Standing Of Cyber Warfare, Kenneth Gualtier

Walden Dissertations and Doctoral Studies

The ever-growing interconnectivity of industry and infrastructure through cyberspace has increased their vulnerability to cyber attack. The lack of any formal codification of cyber warfare has led to the development of contradictory state practices and disagreement as to the legal standing of cyber warfare, resulting in an increased risk of damage to property and loss of life. Using the just war theory as a foundation, the research questions asked at the point at which cyber attacks meet the definition of use of force or armed attack under international law and what impediments currently exist in the development of legal limitations …

Correlations Between Childhood Obesity And Obesogenic Environmental Variables Within Durham County, North Carolina, Eureka Capri Daye
