New Polyanion-Based Cathode Materials For Alkali-Ion Batteries, Hooman Yaghoobnejad Asl

Doctoral Dissertations

"A number of new materials have been discovered through exploratory synthesis with the aim to be studied as the positive electrode (cathode) in Li-ion and Na-ion batteries. The focus has been set on the ease of synthesis, cost and availability of active ingredients in the battery, and decent cycle-life performance through a combination of iron and several polyanionic ligands. An emphasis has been placed also on phosphite (HPO₃^2-) as a polyanionic ligand, mainly due to the fact that it has not been studied seriously before as a polyanion for cathode materials. The concept of mixed polyanions, for …

Efficient Time-Dependent System Reliability Analysis, Zhifu Zhu

Doctoral Dissertations

"Engineering systems are usually subjected to time-variant loads and operate under time-dependent uncertainty; system performances are therefore time-dependent. Accurate and efficient estimate of system reliability is crucial for decision makings on system design, lifetime cost estimate, maintenance strategy, etc. Although significant progresses have been made in time-independent reliability analysis for components and systems, time-dependent system reliability methodologies are still limited. This dissertation is motivated by the need of accurate and effective reliability prediction for engineering systems under time-dependent uncertainty. Based on the classic First and Second Order Reliability Method (FORM and SORM), a system reliability method is developed for multidisciplinary …

Identifying Shallow Subsurface Stratigraphy And Voids Using Dispersive Characteristics Of Electromagnetic And Surface Waves, Payman Hajiani

Doctoral Dissertations

"This dissertation presents the results of three manuscripts on spectral analysis of electromagnetic and seismic surface waves to detect subsurface stratigraphy and voids. In the first manuscript, a new technique was developed by utilizing spectral analysis of surface waves to detect subsurface openings. This technique applied the concept of group delay to evaluate the effects of subsurface voids on the phase shift domain. Seismic data sets were acquired at different sites where the shape, size, and depth of the void varied. In all surveys, the time delay technique precisely identified the locations of the subsurface openings. The second manuscript presents …

Utah Air Quality: Pm 2.5, Randy Martin, Roger Coulombe, Roslynn Brain

All Current Publications

Particulate matter two-point-five (PM_2.5) is a tiny suspended particle of air pollution that can penetrate deeply into our lungs and potentially enter the bloodstream. The 2.5 unit means that the particles are smaller than 2.5 micrometers (a micrometer is one millionth of a meter). In Cache Valley and along the Wasatch Front, these tiny particles form and accumulate to unhealthy levels when air is trapped in the bottom of the valley during cold winter days.

Innovative Techniques For Seismic-Resistant Bridge Columns Under Ground Motion Excitations, Ayman A. Moustafa

Doctoral Dissertations

“This dissertation provides innovative alternative solutions for replacing conventional reinforced concrete columns. The proposed columns displayed enhanced seismic resistance and properties compared to their counterpart conventional columns. Two main techniques were followed and proposed to develop seismic-resistant columns. The first technique utilized rubberized concrete to internally enhance energy dissipation and damping. Materials testing of rubberized concrete with scrap tire replacement of fine aggregates were performed to evaluate its dynamic properties. Shaking table testing of a rubberized concrete column was performed and the behavior was compared to that of the conventional one. The rubberized column showed an increase of 16% in …

The Impact Of Writing Intensive Courses On Writing Apprehension And Academic Motivation, Jacqueline Suzanne Byrket

Graduate Theses/Dissertations

Current research in writing apprehension lacks evaluation of psychology course effectiveness in reducing this trepidation. The present study focused on three psychology courses and utilized Self-Determination Theory (SDT; Deci & Ryan, 1985, 2002) and student instructor rapport to assess changes in writing apprehension. Participants (N = 78) from three upperclass level courses completed the Basic Psychological Needs Scale (BPNS), Academic Motivation Scale (AMS), Daly-Miller Writing Apprehension Test-Revised (WAT-R), and Student Instructor Rapport Scale (SIRS-9) at the beginning and end of the semester. Even though pre-/post-test differences were non-significant for all three courses, the Experimental Psychology class exhibited the greatest decrease …

Using Relevance To Inspire Engagement In Disengaged Secondary Mathematics Students, Cherie Lynn Burkett

Graduate Theses/Dissertations

With the advances being made in technology, our nation is in dire need of a work force degreed with mathematics and science. In the past few decades, the United States has seen a decline in the proportion of college graduates who majored in mathematics-intensive subjects. If our demand is high, why is our supply decreasing? Research suggests that traditional teaching methods using skills-based curricula make it difficult for students to take an interest in a confusing topic like mathematics in which they see no immediate relevance. I have spent a semester engaged in action research taking steps to increase student …

Us Government Antitrust Intervention In Standard-Setting Activities And The Competitive Process, Alden F. Abbott

Vanderbilt Journal of Entertainment & Technology Law

The private sector historically has driven the setting of technical standards in the United States, with the federal government only intervening in response to perceived violations of specific statutes, such as antitrust laws. This concern is reflected in case law and in advice proffered by US antitrust enforcers. Recently, however, US enforcers have turned their attention primarily to the alleged misuse of monopoly power over patents that cover technologies embodied in standards. This new focus threatens to undermine innovation and departs from sound antitrust enforcement policy. American antitrust enforcers should redirect their priorities away from alleged single-firm, patent-related abuses associated …

Innovation Rewards: Towards Solving The Twin Market Failures Of Public Goods, Gregory N. Mandel

Vanderbilt Journal of Entertainment & Technology Law

The challenge of achieving socially optimal incentives for innovation in public goods faces twin market failures: a market failure to adequately promote public goods invention and a market failure to implement innovative public goods once developed. Though innovation in private goods sometimes faces the former hurdle, often ameliorated by intellectual property law, the interaction of both market failures for public goods innovation raises unique difficulties.

Environmentally beneficial technology presents an illustration of the innovation problem for public goods. Private actors lack sufficient incentives both to engage in environmentally beneficial innovation and to implement such innovation. While traditional intellectual property law …

Alternatives To March-In Rights, David S. Bloch

Vanderbilt Journal of Entertainment & Technology Law

The Bayh-Dole Act is an inspired piece of legislation. But its "march-in" provisions are too often a source of confusion and fear for private-sector companies that want to do business with the US government--despite the fact that the government has never exercised its march-in rights. Are there alternatives to march-in rights that would effectively serve the government's public policy needs while eliminating this perceived threat to private intellectual property rights? This Article describes march-in rights in theory and practice, and then weighs several alternatives to traditional Bayh-Dole march-in rights.

Publication Of Government-Funded Research, Open Access, And The Public Interest, Julie L. Kimbrough, Laura N. Gasaway

Vanderbilt Journal of Entertainment & Technology Law

Public access to government-funded research is an issue of tremendous importance to researchers, librarians, and ordinary citizens around the world. Based on the notion that taxpayers finance research through their tax dollars, research data should be available to them. Rapid, unfettered access to research publications provides access to medical research to patients, encourages further exploration and inquiry by other researchers, informs citizens, and advances scientific research.

Scientists typically write articles that divulge the results of their government-funded research. Prior to the open access movement, these articles were published in commercially produced journals. Subscriptions to these journals are expensive, and cost …

Government As Owner Of Intellectual Property? Considerations For Public Welfare In The Era Of Big Data, Ruth L. Okediji

Vanderbilt Journal of Entertainment & Technology Law

Open government data policies have become a significant part of innovation strategies in many countries, allowing access, use and re-use of government data to improve government transparency, foster civic engagement, and expand opportunities for the creation of new products and services. Rarely, however, do open data policies address intellectual property rights that may arise from free access to government data. Ownership of knowledge goods created from big data is governed by the default rules of intellectual property laws which typically vest ownership in the creator/inventor. By allowing, and in some cases actively encouraging, private capture of the downstream goods created …

The Shaky Ground Of The Right To Be Delisted, Miquel Peguera

Vanderbilt Journal of Entertainment & Technology Law

It has long been discussed whether individuals should have a "right to be forgotten" online to suppress old information that could seriously interfere with their privacy and data protection rights. In the landmark case of Google Spain v. Agencia Espafiola de Proteccion de Datos, the Court of Justice of the European Union (CJEU) addressed the particular question of whether, under EU Data Protection Law, individuals have a right to have links delisted from the list of search results in searches made on the basis of their name. It found that they do have this right--which can be best described as …

Lenz V. Universal: A Call To Reform Section 512(F) Of The Dmca And To Strengthen Fair Use, Marc J. Randazza

Vanderbilt Journal of Entertainment & Technology Law

Under 17 U.S.C. § 512(f) of the Digital Millennium Copyright Act (DMCA), those who issue materially false takedown notices are liable for damages. However, Section 512(f) has not effectively protected fair use. Currently, the DMCA issuer only has to prove he considered fair use before issuing a takedown notice, but faces no liability for actually taking action against fair use. The outcome of the recent Ninth Circuit Court of Appeals case Lenz v. Universal shows the flaws in the language of the DMCA. This Article calls for a mild adjustment to Section 512(f) for the purpose of protecting fair use …

How Smart Is Too Smart?: How Privacy Concerns Threaten Modern Energy Infrastructure, Megan Mclean

Vanderbilt Journal of Entertainment & Technology Law

Smart meters are integral to the health of our electric grid and are critical to a reliable, affordable, and efficient energy economy. Yet, collection of smart meter data is raising privacy concerns that are inspiring pockets of resistance to smart meter installation around the country. The fact that these data, like many other kinds of personal information, can and often do flow to the government should not prevent their collection and use. It is critical for environmental and energy regulators to have access to this data to maximize the potential of our energy system. On the state level, several legislatures …

On Climate Change And Cyber Attacks: Leveraging Polycentric Governance To Mitigate Global Collective Action Problems, Scott J. Shackelford

Vanderbilt Journal of Entertainment & Technology Law

Although cyberspace and the atmosphere are distinct arenas, they share similar problems of overuse, difficulties of enforcement, and challenges of collective inaction and free riders. With weather patterns changing, global sea levels rising, and temperatures set to exceed 1.5 degrees Celsius by 2100, climate change is a problem that affects the entire world. Yet its benefits are dispersed, and its harms are often concentrated. Similarly, much of the cost of cyber attacks is focused in a few nations even as others are becoming havens for cybercriminals. Yet it is also true that actions taken by a multiplicity of actors on …

Instrumental And Transformative Medical Technology, Nicole Huberfeld Professor Of Law

Vanderbilt Journal of Entertainment & Technology Law

This Article considers how medical technologies impact universality in health care. The universality principle, as embodied in the Patient Protection and Affordable Care Act (ACA), eliminated widespread discriminatory practices and provided financial assistance to those otherwise unable to become insured--a democratizing federal act that was intended to stabilize health care policy nationwide. This Article posits that medical technology, as with all of medicine, can be universalizing or exclusionary and that this status roughly correlates to its being "instrumental technology" or "transformative technology." Instrumental technology acts as a tool of medicine and often serves an existing aspect of health care; in …

Will The Internet Of Things Transform Healthcare?, Nicolas P. Terry, Professor Of Law,

Vanderbilt Journal of Entertainment & Technology Law

Emerging technologies like health apps on mobile computing platforms and wearable devices are believed to have the potential to improve individual and population health. Increasingly, however, attention should extend to a far larger cohort of connected devices known as the Internet of Things (IoT), an environment in which devices communicate with each other, health apps, and wearables. The resulting Internet of Health Things promises to do things conventional health providers either cannot do or do them faster and cheaper. First, services are "always on, "providing twenty-four/seven monitoring of the patient or pre-patient. Second, the multiple sensors contained in smartphones or …

Customized Medicine And The Limits Of Federal Regulatory Power, Anna B. Laakmann

Vanderbilt Journal of Entertainment & Technology Law

The Food and Drug Administration (FDA) plays a dominant role in setting national policy and standards for the biomedical industry. Yet there are significant statutory constraints on the agency's power. The FDA's main implementing statute, the Federal Food, Drug, and Cosmetic Act (FDCA), bounds the scope of the FDA's regulatory authority. The FDCA cabins FDA power in two important ways: (1) with a few notable exceptions, the FDA lacks power to regulate local activities that are not directly connected to interstate commerce, and (2) the agency may regulate product manufacturers, but not service providers. The FDA has long grappled with …

The Role Of Empathy In Hindsight Bias, Malindi Jeri Gowen

Graduate Theses/Dissertations

Hindsight bias has been operationally defined as "…the tendency for people with outcome knowledge (hindsight) to believe falsely that they would have predicted the reported outcome of an event" (Hawkins and Hastie, 1990, pg. 311). The role of empathy in hindsight bias has not received systematic attention. Previous research has shown that giving participants prevention information increased hindsight bias (Kubany, 2005). Thus, the current study hypothesized that hindsight participants placed in empathic situations should show greater probability judgments for the outcome than hindsight participants in no empathic conditions, and both should be greater than participants in foresight conditions. Participants were …

Complexity In Modern War: Examining Hybrid War And Future U.S. Security Challenges, Joseph Dvorak

Graduate Theses/Dissertations

Hybrid warfare is a recently formed concept that focuses on the complexity of modern conflicts and those in the future. After the Russian Federation annexed the Crimean Peninsula in 2014, US and Western analysts started using the term hybrid warfare to describe Moscow's strategy. Analysts and policymakers are starting to consider the approach and direction in Ukraine to be a new and unique type of warfare. This study discusses the usefulness of the term hybrid warfare and examines two case studies that reflect the characteristics of hybrid war, the conflicts in Syria and Ukraine, to determine if hybrid warfare is …

Analysis And Impact Of Selected Compositions That Endured Criticism, Grant Tyler Simms

Graduate Theses/Dissertations

Throughout the history of Western art music there have been composers who were remarkably successful at creating works that stayed within the guidelines of what was viewed as "acceptable". These composers often were greeted with praise from critics and the general public for these works because they were understood and did not stray outside the boundaries of the expected. While these composers were vital to the development of music, they will not be discussed in this paper. Instead the composers who will be discussed are those who stepped outside the lines of what was viewed as customary. Works ranging from …
