Examining Consumers’ Selective Information Privacy Disclosure Behaviors In An Organization’S Secure E-Commerce Systems, Patrick I. Offor

CCE Theses and Dissertations

The study is an examination of the antecedents to the paradoxical changes in the consumers’ intended and actual personal information disclosure behaviors in online transactions or in e-commerce environments. The argument is that a consumer’s information privacy paradox is based on the consumer’s cognitive predisposition. The study adopted the conceptual underpinning inherent in the Privacy Regulation Theory (PRT) and translated them into information privacy context, as the consumer’s desired state of information privacy, information privacy self-interest, information privacy permeability, and information privacy equipoise constructs, to examine the causal relationship among the constructs and between a consumer’s selective personal information disclosure …

Using Mobile Phones For Teaching And Learning In Chinese Traditional Undergraduate Education, Guchun Huang

CCE Theses and Dissertations

Mobile learning is the new global trend of educational innovation with information and communication technologies. Mobile phones are one major type of mobile technology that can be used for mobile learning. As a highly popular possession among Chinese undergraduate students, as well as among general population, mobile phone usage for learning purposes in the context of Chinese traditional undergraduate education warrants attention from both the education practitioners and researchers. However, very few institutional efforts of promoting mobile phone integrated learning have been reported within the scope of Chinese traditional undergraduate education. A qualitative phenomenological research study was conducted with the …

Assistive Technology Instruction In Teacher Professional Development, David N. Schaaf

CCE Theses and Dissertations

Teachers who work with exceptional students have a critical responsibility to ensure these students receive the best possible education. A major part of the students’ education is the implementation of assistive technology in the classroom. Unfortunately, many teachers begin their career with limited knowledge of assistive technology. Therefore, they are dependent on building their knowledge base from other sources. The results of an assessment of one source, professional development courses, are reported. To assess the effectiveness of the professional development program, a comprehensive prescription was developed to identify gaps in the course objectives and make recommendations to improve the program. …

The Design And Implementation Of Online Radiology Modules Using The Addie Process And Rapid Prototyping, Leslie Bofill

CCE Theses and Dissertations

Medical schools in the United States have begun the process of changing the teaching methodologies used in the classroom. The traditional, teacher-centered environment is shifting toward a more student-centered, active learning environment. Part of this shift is the integration of online learning to deliver a continuously expanding medical curriculum by moving content learning outside the classroom and creating active learning activities for the classroom. As more medical schools adopt online learning as a supplemental teaching tool, medical education faculty are taking on the role of instructional designers without having any theoretical knowledge on adult learning theory or online learning practices. …

Assessing The Effectiveness Of A Fingerprint Biometric And A Biometric Personal Identification Number (Bio-Pin™) When Used As A Multi-Factor Authentication Mechanism, Robert B. Batie

CCE Theses and Dissertations

The issue of traditional user authentication methods, such as username/passwords, when accessing information systems, the Internet, and Web-based applications still pose significant vulnerabilities. The problem of user authentication including physical and logical access appears to have limited, if any, coverage in research from the perspective of biometric as ‘something the user knows.’ Previous methods of establishing ones’ identity by using a password, or presenting a token or identification (ID) card are vulnerable to circumvention by misplacement or unauthorized sharing. The need for reliable user authentication techniques has increased in the wake of heightened concerns about information security and rapid advancements …

Environmentally Sound Energy For The Future, Genevra E L Harker-Klimes

Salish Sea Ecosystem Conference

One of the growing industries in coastal and ocean waters is marine renewable energy. To date, there have been very few deployments in US waters, but the Pacific Northwest National Laboratory’s Marine Sciences Laboratory is conducting research into the environmental impacts of such developments in order to enable the industry to grow. At one time, there were nine tidal projects being investigated within Puget Sound, and none of these has been taken forward. There were several reasons why these projects did not progress but one of the key factors was the cost of the environmental studies. Consequently, there is a …

From The Ivory Tower Through The Black Box: Engaging Effectively With Government To Turn Ideas Into Action, Gabriel Mastico

Salish Sea Ecosystem Conference

When researchers, communities, and/or environmental organizations propose new approaches to address ecological challenges, responsibility for implementing them often falls (in part) to practitioners working within government. Government employees face considerable challenges in synthesizing the available knowledge to support a recommendation for decision-makers to adopt a new approach. This presentation draws on an insider’s experience to help conservation researchers and practitioners understand the key challenges and opportunities that government employees face in navigating their organizations’ decision-making processes. It also suggests best practices to help proponents of new approaches frame conservation finance ideas in ways that resonate with local governments and their …

An Inventory Of Environmental Governance In The Salish Sea, Laurie D. Trautman

Salish Sea Ecosystem Conference

How is the natural environment of the Salish Sea governed? The fact that the Salish Sea is bifurcated by a national border has inhibited our ability to answer this question. Indeed, the Salish Sea involves not only two national governments, but also a multitude of both state and non-state actors, which exist across scales, and interact in different frameworks (i.e. First Nations/tribes often seek only to negotiate with federal, rather than state/provincial governments). Environmental governance in the Salish Sea also encompasses informal modes of interaction involving public and private interest groups, social movements and community stakeholders, in addition to traditional …

Mapping On The Edge: Shoreline Mapping For Regulation And Voluntary Stewardship, Kate E. Emmings

Salish Sea Ecosystem Conference

Nothing generates conversations between landowners and local government like a map! Shoreline mapping is a crucial decision making tool for local governments and regulators. It provides information about appropriate location of shoreline infrastructure, such as docks, and informs landowners about the location of important natural transition areas between the land and the sea. Maps can also provide information that limits the activities of private landowners and as such can cause community conflict if they are inaccurate or unclear. Because mapping can be used to inform regulation, local governments often have different needs than scientists and NGOs, but there is no …

Variable Marsh Resilience To Stress Offers Clues To Climate Change Adaptive Management, Roger Nathan Fuller, Katrina L. Poppe, John M. Rybczyk, Eric Grossman, Chad Stellern

Salish Sea Ecosystem Conference

In Puget Sound’s Stillaguamish estuary, tidal marshes exhibit evidence of multiple stressors that affect their vulnerability and provide insight into adaptive management opportunities to enhance their resilience. Despite high accretion rates, some marsh areas have receded by 10m/yr since 1964. Sources of stress include overgrazing by snow geese, high soil salinities, insect attacks, and changes in flow and inundation patterns. These interact with winter vegetation structure, sediment composition, and wave exposure to result in spatially variable marsh resilience. Some marshes are receding quickly, some slowly, and others are minimally affected. In the context of climate change, with potentially substantial near-term …

Drinking Water And Autism: Using Spatial Cluster Detection To Explore Patterns Of Autism Cases In Lane County, Oregon, Sherry Sandreth

Walden Dissertations and Doctoral Studies

Autism Spectrum Disorders (ASD) are a complex array of neurological disorders with a diverse presentation, multiple etiologies, and long-term ramifications. Prevalence of ASD in the United States is about 1 in 50 children as of 2013, making it a significant public health problem. The etiology is not understood, and it is widely accepted that it is multicausal, with genetic and environmental influences. Prior research suggests an association between water source and ASD. Contaminants such as lead, arsenic, mercury, pharmaceuticals and pesticides found in water are associated with developmental disorders suggesting that a systematic review focused on water source was warranted. …

The Successful Implementation Of Electronic Health Records At Small Rural Hospitals, Daniel Richardson

Walden Dissertations and Doctoral Studies

Electronic health records (EHRs) have been in use since the 1960s. U.S. rural hospital leaders and administrators face significant pressure to implement health information technology because of the American Recovery and Reinvestment Act of 2009. However, some leaders and managers of small rural hospital lack strategies to develop and implement EHRs. The focus of this descriptive phenomenological study was to explore lived experiences of hospital leaders and administrators who have used successful strategies to implement EHRs in small rural hospitals. Diffusion of innovation theory shaped the theoretical framework of this study. Data were collected through telephone interviews conducted with participants …

A Lightweight Security Protocol For Nfc-Based Mobile Payments, Mohamad Badra, Rouba Borghol Badra

All Works

© 2016 Published by Elsevier B.V. In this work, we describe a security solution that can be used to securely establish mobile payment transactions over the Near-Field Communication (NFC) radio interface. The proposed solution is very lightweight one; it uses symmetric cryptographic primitives on devices having memory and CPU resources limitations. We show that our approach maintains the security of NFC communications and we further demonstrate that our solution is simple, scalable, cost-effective, and incurs minimal computational processing overheads.

A Mof-Based Social Web Services Description Metamodel, Amel Benna, Zakaria Maamar, Mohamed Ahmed Nacer

All Works

© Copyright 2016 by SCITEPRESS - Science and Technology Publications, Lda. All rights reserved. To promote and support the development and use of social Web services by the IT community on the Web, both social Web service-based applications and their support platforms should evolve independently from each other while sharing a common model that represents the characteristics of these social Web services. To achieve this duality, this paper proposes a model-driven approach. First, the approach identifies a social Web service's properties. Then a Meta-Object-Facility (MOF)-based social Web services description metamodel is developed. Finally, a prototype illustrates how the MOF-based metamodel …

An Elastic Hybrid Sensing Platform: Architecture And Research Challenges, Sleiman Rabah, Fatna Belqasmi, Rabeb Mizouni, Rachida Dssouli

All Works

© 2016 Published by Elsevier B.V. The dynamic provisioning of hybrid sensing services that integrates both WSN and MPS is a promising, yet challenging concept. It does not only widen the spatial sensing coverage, but it also enables different types of sensing nodes to collaboratively perform sensing tasks and complement each other. Furthermore, it allows for the provisioning of a new category of services that was not possible to implement in pure WSN or MPS networks. Offering a hybrid sensing platform as a service results in several benefits including, but no limited to, efficient sharing and dynamic management of sensing …

Synthesis Of Dmap Tethered Polymer Chains For Reversible Micelle Formation, Richard Arthur Fredricks

Master's Theses and Doctoral Dissertations

Dimethylaminopyridine (DMAP) can act to catalyze numerous organic reactions. To increase its recovery and reuse, it has been tethered to dendrimers and to micellar systems, creating nano-scale catalytic pockets for reactions to proceed. Previously developed systems show diminished reactivity over time as the products of the reaction fill up the nano-scale reactor. Thus, the goal of my research is to use RAFT polymerization methods to synthesize a hydrophobic polymer chain bearing 4-methylaminopyridine units and to attach it to a hydrophilic polymer chain to create a polymer system capable of micelle formation in solution. These functionalized micelles are designed to be …

Construction Of An Optical Fiber Strian Gauge, Najwa Sulaiman

Master's Theses and Doctoral Dissertations

This project is focused on the construction of an optical fiber strain gauge that is based on a strain gauge described by Butter and Hocker. Our gauge is designed to generate an interference pattern from the signals carried on two bare single-mode fibers that are fastened to an aluminum cantilever. When the cantilever experiences flexural stress, the interference pattern should change. By observing this change, it is possible to determine the strain experienced by the cantilever. I describe the design and construction of our optical fiber strain gauge as well as the characterization of different parts of the apparatus.

An Empirical Estimate Of Post-Lgm Grounding-Event Duration In Eastern Ross Sea: Implications From A Comparison With Constraints From New Radiocarbon Dates, Benjamin Krogmeier

LSU Master's Theses

The West Antarctic Ice Sheet (WAIS) advanced to the outer shelf during the Last Glacial Maximum (LGM) before beginning a rapid retreat to the inner shelf. In the Whales Deep paleo-ice-stream trough, subsurface and geomorphologic evidence shows that grounding-line retreat was interrupted by at least five pauses in the area between the shelf edge and the middle shelf. During the pauses, an overlapping cluster of backstepped grounding zone wedges (GZWs) was deposited. Each GZW represents a grounding event, i.e., a time interval during which the grounding-line position was relatively stable. Seismic correlation and isopach mapping show that the cluster has …

Spatiotemporal Distribution Of The Himalayan Leucogranite: Implications For Mountain-Building As A Function Of Indian Slab Dynamics, Hongcheng Guo

LSU Master's Theses

The Himalayan orogen, as a natural laboratory for continental collision, has attracted intense research attention for decades. However, the question of how the orogen was built is still debated, and potential answers are few when considering how and why along-strike variations of the mountain-building processes occurred. Various tectonic models have been proposed to explain the kinematics of the mountain-building. These models include two dimensional models, such as wedge extrusion (Burchfiel and Royden, 1985; Grujic et al., 1996; Kohn, 2008), channel flow coupled to focused denudation (Beaumont et al., 2001; Hodges et al., 2001), tectonic wedging (Yin, 2006; Webb et al., …

Living On The Edge: An Assessment Of The Habitat Use Of Waterbirds In Estuarine Wetlands Of Barataria Basin, La, Brett Ashley Patton

LSU Master's Theses

The wetlands of Louisiana are losing area at the rapid rate of 42.9 km2 yr-1 and the trend is expected to continue. This combined with expected sea-level rise will likely cause large shifts in vegetation and salinity regimes that will affect the wildlife species reliant on these ecosystems. Waterbirds serve as indicator species of ecosystem health in estuarine wetland habitats; therefore, these species are often the targets of wetland management goals in Louisiana. However, many proposed wetland restoration projects are focused primarily on social impacts with only a few specific waterbird species designated for management. The majority of these waterbird …

Interactions Among Hydrology, Sediment And Vegetation In Accreting Wax Lake Delta: Physical And Biogeochemical Implications For Coastal Louisiana Restoration, Courtney Erin Elliton

LSU Master's Theses

River discharge pulses, wind, waves, tides, and the presence of dense vegetation are factors that interact and regulate the transport and retention of sediment in coastal regions. In particular, vegetation structural and physiognomic traits promote fine sediment trapping during tidal and river flow, maintaining the balance between soil elevation and relative sea level rise on coastline stability and land building. Mike Island, located within Wax Lake Delta, Louisiana, USA, is part of a deltaic system created by a man-made freshwater diversion (1941) and one of few coastal areas where land is expanding in coastal Louisiana as result of pulsing river …

Influences On The Successful Implementation Of The Convention On Wetlands Of International Importance (Ramsar) Among Member Countries, Aziza Saud Al Adhoobi

LSU Master's Theses

Wetlands are very dynamic ecosystems and are featured all over the world’s landscape. Recent studies suggested that wetlands are in continuous decline, both and quantity and quality and between 64-71% is the estimated global wetland loss in the 20th century (Davidson 2014; Gardner et al., 2015). Therefore, as wetland loss increases around the world, more effort to protect and restore wetland habitat, values, and services become crucial. For this reason, the Ramsar Convention was established four decades ago to highlight the severity of wetland loss and to produce guidelines that aim to guide Contracting Parties toward sustainable and efficient management …

Computational Progress Towards Maximum Distinguishability Of Bell States By Linear Evolution And Local Measurement, Victor Shang

HMC Senior Theses

Many quantum information protocols rely on the ability to distinguish between entangled quantum states known as Bell states. However, theoretical limits exist on the maximal distinguishability of these entangled states using linear evolution and local measurement (LELM) devices. In the case of two particles entangled in multiple qubit variables, the maximum number of distinguishable Bell states is known. However, in the more general case of two particles entangled in multiple qudit variables, only an upper bound is known under additional assumptions. I have written software in Matlab and Mathematica to explore computationally the maximum number of Bell states that can …

An Interactive Tool For The Computational Exploration Of Integrodifference Population Models, Kennedy Agwamba

HMC Senior Theses

Mathematical modeling of population dynamics can provide novel insight to the growth and dispersal patterns for a variety of species populations, and has become vital to the preservation of biodiversity on a global-scale. These growth and dispersal stages can be modeled using integrodifference equations that are discrete in time and continuous in space. Previous studies have identified metrics that can determine whether a given species will persist or go extinct under certain model parameters. However, a need for computational tools to compute these metrics has limited the scope and analysis within many of these studies. We aim to create computational …

Mathematical Modeling Of Blood Coagulation, Joana L. Perdomo

HMC Senior Theses

Blood coagulation is a series of biochemical reactions that take place to form a blood clot. Abnormalities in coagulation, such as under-clotting or over- clotting, can lead to significant blood loss, cardiac arrest, damage to vital organs, or even death. Thus, understanding quantitatively how blood coagulation works is important in informing clinical decisions about treating deficiencies and disorders. Quantifying blood coagulation is possible through mathematical modeling. This review presents different mathematical models that have been developed in the past 30 years to describe the biochemistry, biophysics, and clinical applications of blood coagulation research. This review includes the strengths and limitations …

The Global Stability Of The Solution To The Morse Potential In A Catastrophic Regime, Weerapat Pittayakanchit

HMC Senior Theses

Swarms of animals exhibit aggregations whose behavior is a challenge for mathematicians to understand. We analyze this behavior numerically and analytically by using the pairwise interaction model known as the Morse potential. Our goal is to prove the global stability of the candidate local minimizer in 1D found in A Primer of Swarm Equilibria. Using the calculus of variations and eigenvalues analysis, we conclude that the candidate local minimizer is a global minimum with respect to all solution smaller than its support. In addition, we manage to extend the global stability condition to any solutions whose support has a single …

A Bound On The Number Of Spanning Trees In Bipartite Graphs, Cheng Wai Koo

HMC Senior Theses

Richard Ehrenborg conjectured that in a bipartite graph G with parts X and Y, the number of spanning trees is at most the product of the vertex degrees divided by |X|⋅|Y|. We make two main contributions. First, using techniques from spectral graph theory, we show that the conjecture holds for sufficiently dense graphs containing a cut vertex of degree 2. Second, using electrical network analysis, we show that the conjecture holds under the operation of removing an edge whose endpoints have sufficiently large degrees.

Our other results are combinatorial proofs that the conjecture holds for …
