Chemical Weapons And Other Atrocities: Contrasting Responses To The Syrian Crisis, Tim Mccormack

International Law Studies

Why has the use of chemical weapons in Syria engendered such a substantive multilateral response in stark contrast to almost every other egregious international law violation perpetrated against the civilian population? Various theories have been offered but the explanation has little to do with humanitarian concerns for Syrian victims and is more readily explicable by unusual (in the Syrian context) alignment of U.S. and Russian national interests. Bashar al-Assad was convinced to accede to the Chemical Weapons Convention, to surrender his stockpiles of chemical weapons and to co-operate with international investigators deployed under UN Security Council auspices amid a cacophony …

A Comparative Study Of Three Approaches For Enhancing Teaching Knowledge Of Dyslexia, Kayla Steltenkamp

Graduate Theses, Dissertations, and Capstones

Teachers are the foundational component of the education system. Annually, they are required to engage in professional development opportunities to expand their knowledge. Since 1985 there has been a profusion of legislative attention to the reading disability dyslexia. Included in legislation is the mandate for teacher training, but there is a lack of research on effective professional development to increase teacher knowledge of dyslexia. This study compared three models of professional development to assess their efficacy in increasing declarative knowledge of dyslexia for elementary general education teachers. The results indicated that the use of simulation training alone was less effective …

A Binding Energy Study Of The Atomic Mass Evaluation 2012 And An Updated Beta-Decay Study Of Neutron-Rich 74cu, James L. Tracy Jr

Theses and Dissertations

A study of ground state binding energy values listed in the Atomic Mass Evaluation 2012 (AME2012) using an interpretive approach, as opposed to the exploratory methods of previous models, is presented. This model is based on a postulate requiring all protons to pair with available neutrons to form bound alpha clusters as the ground state for anN = Z core upon which excess neutrons are added. For each core, the trend of the binding energy as a function of excess neutrons in the isotopic chain can be fit with a three-term quadratic function. The quadratic parameter reveals a smooth decaying …

A Detailed Look Into The Aerodynamic Forces Due To The Drag-Reducing Aerospike, Philip Douglas

Theses and Dissertations

This thesis aims to simulate previous wind tunnel experiments on the drag-reducing aerospike in order to help validate the accuracy of CFD analysis. Multiple grids were created with the Pointwise grid generation software. The CFD analysis software used was Ansys Fluent, with both planar and axisymmetric cases being tested for the primary rocket in order to compare the differences. The tests with the primary rocket followed how a spike of set length reacted at various speeds. Two additional experiments were duplicated. These helped confirm that the results obtained via Fluent were accurate. One case was a simple transonic spike model, …

Members enlist to serve schools and communities for 1 year, possibly 2. Upon completion of a member’s year(s) of service an education award is given which can be used to attend a community college, university or repay student loans. This study showed how AmeriCorps/America Reads programs partnered with community colleges and universities which recruited members to volunteer at school sites and community centers tutoring students in classrooms to improve reading, grades, engage in community service activities, use education …

An Analysis Of The Relationship Between College Football Fans And Their Rival Teams, Morgan Young

Theses and Dissertations

The current study explored how fan identification and negative rival perception affect the decision to blast or support the rival in indirect competition in college football. 258 participants (M age=24.15, 51.16% female) responded after being targeted via social media, email, and in person. Fans higher in identification had a more negative rival perception, were more likely to blast the rival, and were less likely to support the rival in indirect competition. A negative rival perception increased blasting and decreased rival support. The results contribute to current literature on rivalry and fan identification and aid marketers in marketing segmentation and targeting …

Gaskinetic Modeling On Dilute Gaseous Plume Impingement Flows, Chunpei Cai

This paper briefly reviews recent work on gaseous plume impingement flows. As the major part of this paper, also included are new comprehensive studies on high-speed, collisionless, gaseous, circular jet impinging on a three-dimensional, inclined, diffuse or specular flat plate. Gaskinetic theories are adopted to study the problems, and several crucial geometry-location and velocity-direction relations are used. The final complete results include impingement surface properties such as pressure, shear stress, and heat flux. From these surface properties, averaged coefficients of pressure, friction, heat flux, moment over the entire flat plate, and the distance from the moment center to the flat …

Canine Pure Platelet-Rich Plasma For Regenerative Medicine And Platelet Research: Protocol Optimization, Marina Mitie Monobe

Theses and Dissertations

Platelet-rich plasma (PRP) can be widely used in veterinary medicine in different areas. Studies using PRP frequently use different methodologies making for difficult comparison. The objective of this study was to evaluate the purity and platelet activation of a PRP protocol. A total of 18 blood samples were drawn from six dogs, collected once per week over a total of three weeks. Blood samples were centrifuged six times at 300g for 5 min. Ultra-pure PRP (OP) was obtained by adding PRP a Optiprep 1.063g/mL density barrier and centrifuged at 350g for 15 min. Mean platelet recovery from whole blood was …

Carbon Emissions Embodied In International Trade And Carbon Sequestration Of Harvested Wood Products, Prativa Shrestha

Theses and Dissertations

After timber harvesting, carbon in wood is transferred to products pool and remains entrapped for a considerable time. It is necessary to estimate this carbon flux in the harvested wood products (HWP); otherwise, carbon emission estimates of a country will be overestimated at the time of harvest. Furthermore, carbon estimates of the HWP must be assessed for uncertainties which need to be reduced as far as possible. Environmental implications might be associated with the HWP traded in the national and international markets. In the current context, there is a lack of economic-environmental studies that relate to the trade of HWP. …

Droplet Impact On Dry, Superhydrophobic Surfaces With Micro-Scale Roughness Elements, Nadine Boufous

Theses and Dissertations

Most aircraft accidents are caused by technical problems or weather-related issues. One cause of weather-related incidents is inlight icing, which can induce negative performance characteristics and endanger the operation of an airplane. Various researchers investigating the problem of inlight icing have proposed ice-phobic coatings as one viable solution. For this purpose, it is critical to study the behavior of a droplet impact on different types of surfaces. As an alternative to physical testing, three-dimensional numerical simulation using computational fluid dynamics offers a promising strategy for evaluating the effects of surface characteristics. Using the volume of fluid method, three simulations of …

Effect Of Small Steps On The Receptivity And Transition In High Speed Boundary Layer, Sofia Yassir

Theses and Dissertations

The research on transition in supersonic and hypersonic boundary layers has been reinvigorated in the last decades because of the increased interest in high-speed flight. The receptivity to environmental disturbances of high-speed boundary layers developing over flat plates or curved surfaces is a very important problem because the transition process is directly impacted by it. The main objective of the research is to determine the effect of small steps on laminar high-speed boundary-layers that are excited by freestream disturbances in the form of vorticity and acoustic waves. Both supesonic and hypersonic regimes are analyzed using a high-order compressible Navier-Stokes numerical …

Internal State Variable Plasticity-Damage Modeling Of Aisi 4140 Steel Including Microstructure-Property Relations: Temperature And Strain Rate Effects, Reda Nacif El Alaoui

Theses and Dissertations

Mechanical structure-property relations have been quantified for AISI 4140 steel under different strain rates and temperatures. The structure-property relations were used to calibrate a microstructure-based internal state variable plasticity-damage model for monotonic tension, compression and torsion plasticity, as well as damage evolution. Strong stress state and temperature dependences were observed for the AISI 4140 steel. Tension tests on three different notched Bridgman specimens were undertaken to study the damage-triaxiality dependence for model validation purposes. Fracture surface analysis was performed using Scanning Electron Microscopy (SEM) to quantify the void nucleation and void sizes in the different specimens. The stress-strain behavior exhibited …

Copper Coordination With Protein, Peptides, And Small Molecules, Whitnee Leigh Nettles

Theses and Dissertations

Copper is an essential element for all living organisms. However, due to its low redox potential it can be involved in the production of reactive oxygen species; where excess amounts of copper can be exceptionally toxic.1 In humans, malfunctions in copper metabolism are linked to diseases such as Menkes syndrome, Wilson’s disease, prion disease, and Alzheimer’s disease.2 Maintenance of copper homeostasis requires a number of proteins, such as copper transporters and chaperones to deliver copper to the correct protein while limiting free copper in the cell.3 Therefore, understanding the thermodynamics of copper(II) coordination in proteins is critical to our understanding …

Coupled And Uncoupled Earth Pressure Profiles In Unsaturated Soils Under Transient Flow, Syed Gous Andrabi

Theses and Dissertations

The main goal of this research is to evaluate the behavior of earth pressure profiles in unsaturated soils under transient flow. In the first part, an empirical correlation is proposed to obtain the fitting parameters of Brooks and Corey’s soil-water retention model from Fredlund and Xing’s model. The retention models and the proposed equivalency between the models were assessed for 601 soil samples from the unsaturated soils hydraulic database (UNSODA). In the second part, a coupled one-dimensional hydro-mechanical model is introduced and is implemented into Rankine’s earth-pressure model to represent active and passive earth pressure profiles in unsaturated soils under …

Novel And Lost Forests In The Upper Midwestern United States, From New Estimates Of Settlement-Era Composition, Stem Density, And Biomass, Simon J. Goring, David J. Mladenoff, Charles V. Cogbill, Sydne Record, Christopher J. Paciorek, Stephen T. Jackson, Michael C. Dietze, Andria Dawson, Jaclyn Hatala Matthes, Jason S. Mclachlan, John W. Williams

Dartmouth Scholarship

EuroAmerican land-use and its legacies have transformed forest structure and composition across the United States (US). More accurate reconstructions of historical states are critical to understanding the processes governing past, current, and future forest dynamics. Here we present new gridded (8x8km) reconstructions of pre-settlement (1800s) forest composition and structure from the upper Midwestern US (Minnesota, Wisconsin, and most of Michigan), using 19th Century Public Land Survey System (PLSS), with estimates of relative composition, above-ground biomass, stem density, and basal area for 28 tree types. This mapping is more robust than past efforts, using spatially varying correction factors to accommodate sampling …

James D. Cox: The Shareholders’ Best Advocate, Randall S. Thomas, Harwell Wells

Duke Law Journal

This Article explores the historical development of the academic analysis of corporate law over the past forty years through the scholarship of one of its most influential commentators, Professor James D. Cox of the Duke University School of Law. It traces the ways in which corporate law scholarship changed from the 1970s to the present, including the rise of economic theory and empirical work in the study of corporate law. It shows how Professor Cox’s early scholarship shaped and challenged economic orthodoxy, while his later work used empirical analysis to help corporate law become a more dynamic and richer field. …

The Role Of Blue Sky Laws After Nsmia And The Jobs Act, Rutheford B. Campbell Jr.

Duke Law Journal

State securities laws—in particular, state laws requiring that securities offered by issuers be registered with the states—have been an impediment to the efficient movement of capital to its highest and best use. The pernicious effects of these laws—generally referred to as “blue sky laws”—have been felt most acutely by small businesses, a vital component of our national economy.

It has been difficult to remedy this problem. States and state regulators have been tenacious in protecting their registration authority from federal preemption. The Securities and Exchange Commission, on the other hand, has been reluctant to advocate for preemption and unwilling to …

The Knowledge Gap In Workplace Retirement Investing And The Role Of Professional Advisors, Jill E. Fisch, Tess Wilkinson-Ryan, Kristin Firth

Duke Law Journal

The dramatic shift from traditional pension plans to participant-directed 401(k) plans has increased the obligation of individual investors to take responsibility for their own retirement planning. With this shift comes increasing evidence that investors are making poor investment decisions.

This Article seeks to uncover the reasons for poor investment decisions. We use a simulated retirement investing task and a new financial literacy index to evaluate the role of financial literacy in retirement investment decisionmaking in a group of nonexpert participants. Our results suggest that individual employees often lack the skills necessary to support the current model of participant-directed investing. We …

Regulating Public Offerings Of Truly New Securities: First Principles, Merritt B. Fox

Duke Law Journal

The public offering of truly new securities involves purchases by investors in sufficient number and in small enough blocks that each purchaser’s shares can reasonably be expected to be freely tradable in a secondary market that did not exist before the offering. Increasing the ability of small and medium-sized enterprises (SMEs) to make such offerings has been the subject of much recent discussion.

At the time that a firm initially contemplates such an offering, unusually large information asymmetries exist between its insiders and potential investors. These can lead to severe adverse-selection problems that prevent a substantial portion of worthy offerings …

How Understanding The Nature Of Corporate Norms Can Prevent Their Destruction By Settlements, James D. Cox

Duke Law Journal

Scholars have long celebrated the importance of norms in corporate law. Indeed, norms likely guide corporate actors more than the omnipresent threat of shareholder suits. This Article divides corporate norms into two distinct groups: aspirational norms and arbiter norms. Aspirational norms announce socially desirable objectives for corporate managers and encourage certain disclosure practices; arbiter norms identify distinct transactions for closer scrutiny by an independent body, the court. This Article shows that even though aspirational norms and arbiter norms serve different objectives, they share a common characteristic—overbreadth. This feature exists whether the norm is set forth by statute or found in …

Using The False Claims Act To Remedy Tax-Expenditure Fraud, Ian Ayres, Robert Mcguire

Duke Law Journal

The federal False Claims Act (FCA) may be a tool for combating fraudulent claims regarding tax expenditures. The FCA has been used to protect the public fisc by imposing liability upon anyone who makes a false or fraudulent claim relating to an expenditure of federal funds. A substantial share of government spending is implemented through tax credits and deductions granted to individuals and entities for taking particular actions promoted by the tax code—so-called “tax expenditures.” Funds subsidized by such tax expenditures can themselves be the objects of fraud. For example, a taxpayer could be defrauded of retirement funds that the …

Detecting Good Public Policy Rationales For The American Rule: A Response To The Ill-Conceived Calls For “Loser Pays” Rules, Peter Karsten, Oliver Bateman

Duke Law Journal

Several critiques have been leveled at the American Rule—that is, the rule that each party to a lawsuit should pay for its attorneys. Some claim that there were no principled justifications offered by the nineteenth-century jurists who authored the opinions marking the rule’s origins. Instead, these jurists only cited their states’ “taxable costs” statutes. Others claim that the American Rule—as well as its close relative, the contingency-fee contract—contributed to a “liability explosion” in that century. This Article offers a comprehensive examination of the origins of, rationales given for, and impact of the American Rule; then it evaluates instances in which …

“We Believe”: Omnicare, Legal Risk Disclosure And Corporate Governance, Hillary A. Sale, Donald C. Langevoort

Duke Law Journal

The Supreme Court’s decision in Omnicare Inc. v. Laborers District Council Construction Industry Pension Fund presents new challenges for boards of directors. The opinion speaks to whether and when an issuer’s statement of belief can be false or misleading other than by proof that the issuer’s genuine opinion was different from what it stated. Statements of opinion imply something about how the belief was formed, and that process implicates the role of directors as fiduciaries.

This Article uses Omnicare as a starting point for exploring and developing the interplay between disclosure, discourse, and fiduciary duties. Using the lens of corporate-discourse …

Adaptive Financial Regulation And Regtech: A Concept Article On Realistic Protection For Victims Of Bank Failures, Lawrence G. Baxter

Duke Law Journal

Frustrated by the seeming inability of regulators and prosecutors to hold bank executives to account for losses inflicted by their companies before, during, and since the financial crisis of 2008, some scholars have suggested that private-attorney-general suits such as class action and shareholder derivative suits might achieve better results. While a few isolated suits might be successful in cases where there is provable fraud, such remedies are no general panacea for preventing large-scale bank-inflicted losses. Large losses are nearly always the result of unforeseeable or suddenly changing economic conditions, poor business judgment, or inadequate regulatory supervision—usually a combination of all …

The Impact Of Metacomprehension Accuracy On Control Processes During Comprehension, Elaine Wei-Ling Tan

Theses and Dissertations

The aim of this dissertation was to investigate whether improving metacomprehension accuracy via the monitoring process impacted learning strategy selection implemented by the control process so that comprehension was also improved. A new paradigm—the multi trial metacomprehension paradigm—was introduced to investigate this aim. Participants studied a text using an effective or ineffective learning strategy, made metacomprehension predictions about their future comprehension, and took a comprehension test; there were three trials of this procedure. The goal was to determine whether metacomprehension accuracy improved—leading to improved comprehension accuracy—for the third trial. Experiment 1 tested whether metacomprehension accuracy improved across multiple trials when …

The Influence Of A Graphing Calculator Program Policy Change On The Algebra I High Stakes Assessment In Mississippi, Elizabeth Anderson Repsher

Theses and Dissertations

Graphing calculator programs have been used on high-stakes tests and teacher-created assessments at the secondary and college level for many years. These programs- are even used on college-placement tests such as the ACT. Beginning with the 2011-2012 school year, the Mississippi Department of Education (MDE) made the decision to no longer allow the use of graphing calculator applications and/or programs on the Subject Area Testing Program (SATP2) for Algebra I. Currently, limited research exists to address the influence of graphing calculator program use on high-stakes assessments. The programming capabilities of graphing calculators should not be ignored. Because of the 2011-2012 …

Relationships Between Information Technology Skills And Performance Evaluation Scores Of Mississippi State University Extension Service Agents, James R. Loper

Theses and Dissertations

A study was conducted to see if the level of use, expertise, and problem solving abilities using information technology among Mississippi State University Extension agents was positively correlated with the performance quality of the agent as measured in the Mississippi State University Extension Service agent evaluation system. A second purpose was to examine how well agents self-assess their technology skills. Lastly, the study attempted to determine if there was a set of factors (including information technology skills) that explained a substantial portion of the variation in performance evaluation scores. The results showed that the Mississippi State University Extension agent evaluation …

Role Of Selenium In Age-Related Degeneration: Selenotranscriptome Hierarchy And Characterization Of Selenoprotein H, Lei Cao

Theses and Dissertations

Selenium (Se) is an essential trace element exerting its biological functions mainly through selenoproteins. Our lab has recently shown a paradoxical role of dietary Se at nutritional levels of intake in the delay of age-related degeneration while reducing longevity in mice carrying humanized telomeres. The first aim of this dissertation was to evaluate the effects of long-term dietary Se deficiency, aging, and sex on selenotranscriptome hierarchy in tissues. Four unique patterns in selenotranscriptomic changes were summarized. First, the responses of selenotranscriptomes to dietary Se deprivation and aging were sexually dimorphic. Second, a few selenoproteins responded to dietary Se deficiency and …
