Learning Disability Status And Gender As Predictors Of Self-Efficacy., Irene Ekohamen Aikhomu

Walden Dissertations and Doctoral Studies

In the school district under study, students with learning disabilities were

underperforming when compared to students without disabilities. Research has indicated that improved self-efficacy can promote improved student outcomes and that self- efficacy can be taught. Despite this known association, the school district under study has not provided students with such support. The current study addressed ways in which that gap may be attenuated. Guided by the framework of Bandura's theory of self-efficacy and social cognitive theory, the purpose of this study was to explore (a) whether students' perceptions of self-efficacy differed depending on whether or not they had diagnosed …

Assessing Student Leadership Competencies And Adequacy Of Preparation In Seminary Training, Valerie Miles-Tribble

Walden Dissertations and Doctoral Studies

As more seminary student-practitioners seek non-pastoral leadership roles in faith-based

and secular organizations, the complexities of the roles demand leadership competencies beyond traditional religious study. Limited research assessing leadership competencies in seminary contexts raises uncertainty about whether leadership preparation needs are addressed adequately in seminary. This quantitative study focused on whether or not student self-assessed adequacy of preparation is related to, affected by, or influenced by self-assessed leadership competencies, individually or in the aggregate. The theoretical foundation joined Evers, Rush, and Berdrow's learner-centered theory that urges student input on competency development needs and Boyatzis's leadership competency theory that frames a …

A Knowledge-Driven Distributed Architecture For Context-Aware Systems, Dennis Lupiana

Doctoral

As the number of devices increases, it becomes a challenge for the users to use them effectively. This is more challenging when the majority of these devices are mobile. The users and their devices enter and leave different environments where different settings and computing needs may be required. To effectively use these devices in such environments means to constantly be aware of their whereabouts, functionalities and desirable working conditions. This is impractical and hence it is imperative to increase seamless interactions between the users and devices,and to make these devices less intrusive. To address these problems, various responsive computing systems, …

Building A Scalable Global Data Processing Pipeline For Large Astronomical Photometric Datasets, Paul F. Doyle

Doctoral

Astronomical photometry is the science of measuring the flux of a celestial object. Since its introduction in the 1970s the CCD has been the principle method of measuring flux to calculate the apparent magnitude of an object. Each CCD image taken must go through a process of cleaning and calibration prior to its use. As the number of research telescopes increases the overall computing resources required for image processing also increases. As data archives increase in size to Petabytes, the data processing challenge requires image processing approaches to evolve to continue to exceed the growing data capture rate. Existing processing …

Reference Material Development For Paralytic Shellfish Poisoning Toxins And Associated Analytical Applications, Stephen Burrell

Doctoral

Food poisoning incidences relating to marine biotoxins are a global phenomenon and have the potential to severely impact the aquaculture industry. As a result, and as a legislative requirement in the European Union (EU), many countries have implemented monitoring programmes for these compounds but their success relies on the availability of certain quality assurance tools, two of which are reference materials (RMs) and proficiency testing. The limited amounts of RMs, in particular matrix certified reference materials (CRMs) for paralytic shellfish poisoning (PSP) toxins has been a limiting factor in the implementation of alternatives to the mouse bioassay for routine monitoring …

Applying The Analytic Hierarchy Process To Oil Sands Environmental Compliance Risk Management, Izak Johannes Roux

Walden Dissertations and Doctoral Studies

Oil companies in Alberta, Canada, invested $32 billion on new oil sands projects in 2013. Despite the size of this investment, there is a demonstrable deficiency in the uniformity and understanding of environmental legislation requirements that manifest into increased project compliance risks. This descriptive study developed 2 prioritized lists of environmental regulatory compliance risks and mitigation strategies and used multi-criteria decision theory for its theoretical framework. Information from compiled lists of environmental compliance risks and mitigation strategies was used to generate a specialized pairwise survey, which was piloted by 5 subject matter experts (SMEs). The survey was validated by a …

Images Of Harassment: Copyright Law And Revenge Porn, Ari Ezra Waldman

Other Publications

Nonconsensual pornography, commonly known as “revenge porn,” usually occurs when an individual (usually a man) publicly posts online sexually explicit images of his former partner (usually a woman). Although normally the stuff of tort law, revenge porn offers copyright attorneys opportunities to help victims, as well: the offending images are often selfies taken by the victim and thus covered by the victim’s copyright. There is, to date, no Second Circuit case law on the subject, making this area uniquely suited to creative social impact litigation. Until state legislatures or Congress pass well-drafted criminal revenge porn statutes, copyright law remains a …

Patent Stewardship, Choice Of Law, And Weighing Competing Interests, David O. Taylor

Faculty Journal Articles and Book Chapters

Xuan-Thao Nguyen’s recent article, "In the Name of Patent Stewardship: The Federal Circuit’s Overreach into Commercial Law", is important for at least two potential reasons that Nguyen herself highlights. First, to the extent that the Federal Circuit’s decisions related to commercial law differ from state courts’ decisions related to commercial law, it might call into question the Federal Circuit’s competency with respect to commercial law. And, second, it certainly highlights something that practitioners might need to know to adapt their advice and strategies for reaching their clients’ desired ends. But Nguyen’s critique is important for a third reason. Assuming the …

Legislative Responses To Patent Assertion Entities, David O. Taylor

Faculty Journal Articles and Book Chapters

While the existence of patent assertion entities is not new, in recent years they have proliferated, spawning debate concerning their impact on the patent system and, more broadly, on technological innovation. Despite the fear that they instill in their targets — or perhaps because of it — patent assertion entities arguably serve a beneficial purpose in the patent system. Theoretically they should be able to help individual inventors and small businesses, in particular, obtain a return on their investment in research and development. To the extent patent assertion entities assert patent claims that should be held invalid, not infringed, or …

Walden Dissertations and Doctoral Studies

Highly qualified individuals are leaving the Caribbean and relocating to the United States and other developed countries. Researchers describe this resulting flight of human capital, or brain drain, from the Caribbean as a problem which has no clear definition or immediate solution. This phenomenological study explored perceptions of government senior executives in the United States Virgin Islands (USVI) of the cause and impact of brain drain. Burns' and Bass's transformational and transactional leadership theories were used as the framework for this study. Data were collected through a demographic questionnaire and semistructured interviews with a snowball sample of 10 participants. Data …

Beyond Elections: Ghana's Democracy From The Perspective Of The Citizenry, Ransford Osafo-Danso

Walden Dissertations and Doctoral Studies

Ghana's democracy has been hailed by scholars, practitioners, and the international community in recent years as a shining example in the West African subregion as a result of the country's record of organizing successive elections with minimal or no violence. However, the evaluation of Ghana's democracy has predominantly focused on the elections and disproportionately captures the views of the political elite; conspicuously missing is the perspective of the ordinary Ghanaian. This presents an incomplete picture of Ghana's democracy, given the relevance of citizens' participation in democratic societies. To address this gap in knowledge, this qualitative case study explored the practice …
