All-Inclusive List of Electronic Theses and Dissertations

The purpose of this study is to firmly establish the facet scales of the Personality Psychopathology Five (PSY-5) Psychoticism scale of the Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2). Arnau, Handel, and Archer (2005) recently developed facet scales for the MMPI-2 PSY-5 scales using principal component analyses. The results of this study and the original published study were compared to determine if similar facet scales are found for the MMPI-2 PSY-5 Psychoticism scale. Participants were drawn from three different samples: the MMPI-2 normative sample, an inpatient sample from a mid-Atlantic region, and a college sample from a Midwestern university. Item-level principal …

Internal Magnetic Structure Of Magnetite Nanoparticles At Low Temperature, Kathryn L. Krycka, Julie A. Borchers, R.A. Booth, C.R. Hogg, Yumi Ijiri, W.C. Chen, S.M. Watson, M. Laver, T.R. Gentile, S. Harris

Faculty & Staff Scholarship

Small-angle neutron scattering with polarization analysis reveals that Fe3O4 nanoparticles with 90 Å diameters have ferrimagnetic moments significantly reduced from that of bulk Fe3O4 at 10 K, nominal saturation. Combined with previous results for an equivalent applied field at 200 K, a core-disordered shell picture of a spatially reduced ferrimagnetic core emerges, even well below the bulk blocking temperature. Zero-field cooling suggests that this magnetic morphology may be intrinsic to the nanoparticle, rather than field induced, at 10 K.

Design And Analysis Of An Fpga-Based, Multi-Processor Hw-Sw System For Scc Applications, Andrew Fitzgerald

Theses

The last 30 years have seen an increase in the complexity of embedded systems from a collection of simple circuits to systems consisting of multiple processors managing a wide variety of devices. This ever increasing complexity frequently requires that high assurance, fail-safe and secure design techniques be applied to protect against possible failures and breaches. To facilitate the implementation of these embedded systems in an efficient way, the FPGA industry recently created new families of devices. New features added to these devices include anti-tamper monitoring, bit stream encryption, and optimized routing architectures for physical and functional logic partition isolation. These …

Scalable Event Tracking On High-End Parallel Systems, Kathryn Marie Mohror

Dissertations and Theses

Accurate performance analysis of high end systems requires event-based traces to correctly identify the root cause of a number of the complex performance problems that arise on these highly parallel systems. These high-end architectures contain tens to hundreds of thousands of processors, pushing application scalability challenges to new heights. Unfortunately, the collection of event-based data presents scalability challenges itself: the large volume of collected data increases tool overhead, and results in data files that are difficult to store and analyze. Our solution to these problems is a new measurement technique called trace profiling that collects the information needed to diagnose …

An Econometric Analysis Of Australian Domestic Tourism Demand, Ghialy C. Yap

Theses: Doctorates and Masters

In 2007, the total spending by domestic visitors was AUD 43 billion, which was 1.5 times higher than the aggregate expenditure by international tourists in Australia. Moreover, domestic visitors consumed 73.7% of the Australian produced tourism goods and services whereas international tourists consumed 26.3%. Hence, this shows that domestic tourism is an important sector for the overall tourism industry in Australia. This present research determines the factors that influence domestic tourism demand in Australia and examines how changes in the economic environment in Australia could influence this demand. The main aim of this research is to achieve sustainability of domestic …

Numerical Simulation Of Capsule Dissolution In The Usp Apparatus Ii, Jasmine Han

Master's Theses

The capsule is the second most common type of drug dosage form, yet detailed research of capsule dissolution in the USP Apparatus II (a paddle dissolution apparatus that mimics the drug dissolution process in an in vivo environment) is not well reported. In this work, a mathematical model was developed that incorporates both the dissolution of the capsule shell and the slug within the capsule shell. Capsule shell dissolution was modeled with the assumption that the shell undergoes an erosion process only. The capsule slug dissolution model incorporated mass transfer principles, Markov chain theory, and the influence of hydrodynamics on …

From Medical Images To Individualized Cardiac Mechanics: A Physiome Approach, Chun Wong

Theses

Cardiac mechanics is a branch of science that deals with forces, kinematics, and material properties of the heart, which is valuable for clinical applications and physiological studies. Although anatomical and biomechanical experiments are necessary to provide the fundamental knowledge of cardiac mechanics, the invasive nature of the procedures limits their further applicability. In consequence, noninvasive alternatives are required, and cardiac images provide an excellent source of subject-specific and in vivo information. Noninvasive and individualized cardiac mechanical studies can be achieved through coupling general physiological models derived from invasive experiments with subject-specific information extracted from medical images. Nevertheless, as data extracted …

Tax Fraud In The Sales Tax: Zappers — What Are They? How Can Puerto Rico Block Them?, Richard Thompson Ainsworth

Faculty Scholarship

The Sales and Use Tax is an essential part of Puerto Rico’s revenue profile. Effective only recently (November 15, 2006) the Impuesto a las Ventas y Uso (IVU) was expected to raise between $2.3 and $1.05 billion annually, and has already become the Commonwealth’s fourth largest revenue source. Actual revenue results for 2007-2008 came in at $1.1 billion, which admittedly is closer to the low end than the high end of what is possible, but now that the tax is in place the next pressing question is how can its performance be improved?

This paper generally proposes that Puerto Rico …

Complimentary And Complementary Discrimination In Faculty Hiring, Angela Onwuachi-Willig

Faculty Scholarship

This Article focuses on one form of discrimination in faculty hiring. Specifically, this Article concentrates on discrimination against the "overqualified" minority faculty candidate, the candidate who is presumed to have too many opportunities and thus gets excluded from faculty interview lists and consideration. In so doing, this Article poses and answers the question: "Can exclusion from interviewing pools and selection based upon the notion that one is just 'too good' to recruit to a particular department constitute an actionable form of discrimination?" Part I of this Article begins by briefly reviewing the changes in faculty diversity and inclusion at colleges …

Retributivism Refined - Or Run Amok?, Kenneth Simons

Faculty Scholarship

What would the criminal law look like if we took retributivist principles very seriously? In their book, Crime and Culpability: A Theory of Criminal Law, the authors - Larry Alexander and Kimberly Kessler Ferzan, with contributions by Stephen J. Morse - provide a controversial set of answers. Whether a criminal act does ordoes not result in harm should not affect the actor’s punishment. Only the last act of risk creation should suffice for liability. Conscious awareness of risk should always be necessary. And all of criminal law, each and every category of mens rea and actus reus, should be reduced …

Local And Traditional Knowledge And The Historical Ecology Of Pacific Herring In Alaska, Thomas F. Thornton, Madonna L. Moss, Virginia L. Butler, Jamie Hebert, Fritz Funk

Anthropology Faculty Publications and Presentations

The article focuses on the historical ecology of the Pacific herring, a marine food web resource, in the Gulf of Alaska. It states the hearing conducted by the Alaska Legislature's House special committee on fisheries on the status and management of herring in Southeast Alaska during which Tlingit fisherman Clarence Jackson of Kake notes the disappearance of herring in his lifetime. Information on herring ecology based from Native and non-Native individuals from Southeast communities and archaeological site reports reveal that non-Natives in Southeast Alaska have exploited herring with the development of a herring reduction plant. It underscores the need for …

Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler

Anthropology Faculty Publications and Presentations

Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the …

The Psychology Of Good Character, Alice Woolley, Jocelyn Stacey

All Faculty Publications

This paper explores the significance of the changing nature of the good character requirement for law society admission in Canada. It posits that good character has shifted from a philosophical concept into a psychological concept, with evidence of past bad acts claimed to be relevant for whether an applicant represents a future risk to the public. This shifting conception of character has, however, been only partial, and the decision-making processes of Canadian law societies have not kept pace with it. Instead, the decision-making process defines character generally and generically, with only occasional emphasis on character as a relevant predictor of …

Power Series Expansions For Waves In High-Contrast Plasmonic Crystals, Santiago Prado Parentes Fortes

LSU Doctoral Dissertations

In this thesis, a method is developed for obtaining convergent power series expansions for dispersion relations in two-dimensional periodic media with frequency dependent constitutive relations. The method is based on high-contrast expansions in the parameter _x0011_ = 2_x0019_d=_x0015_, where d is the period of the crystal cell and _x0015_ is the wavelength. The radii of convergence obtained are not too small, on the order of _x0011_ _x0019_ 10􀀀2. That the method applies to frequency dependent media is an important fact, since the majority of the methods available in the literature are restricted to frequency independent constitutive relations. The convergent series …

Athens And Byzantium: Platonic Political Philosophy In Religious Empire, Jeremiah Heath Russell

LSU Doctoral Dissertations

It is traditionally understood that there is a gap, which spans well over one thousand years, between Plato’s own political philosophy and its successor in medieval Islamic philosophy. A most likely bridge between Plato and these later philosophers is Neoplatonism. However, scholars argue that this philosophic school abandoned its predecessor’s emphasis on political philosophy. This dissertation challenges the traditional interpretation by reconstructing a political philosophy based on a Neoplatonic commentary on Plato’s Gorgias. The first two chapters place this commentary within its historical context, as well as its place within the larger Neoplatonic pedagogy. The remainder of the dissertation reconstructs …

Positron Autoradiography For Intravascular Vulnerable Plaque Imaging, Peter Petrek

LSU Master's Theses

Purpose: To develop and investigate an intravascular storage phosphor detector for imaging and detection of vulnerable coronary artery plaques. Methods: The concept of the detection of vulnerable plaques (i.e., plaques with inflammation) is based on accumulation of fluorodeoxyglucose (FDG) in inflammation sites. The FDG is labeled with a radioactive isotope 18F (positron source), injected to patient, and accumulated in vulnerable plaques of coronary arteries. The radiation detector is then inserted into coronary artery, records positrons from FDG accumulated in vulnerable plaque, which allows for imaging and detection of the vulnerable plaque. A prototype detector was developed and tested. The detector …

Although this thesis focuses on one state’s court system’s response to two natural disasters, the research, conclusions and recommendations are transferable to other states. Hurricanes Katrina and Rita struck the Gulf Coast in 2005 devastating large areas in Louisiana, Texas, Mississippi and Alabama. Millions of people, including judges and attorneys, were forced to evacuate their homes, courts and law offices. The Hurricanes caused interruptions to both federal …

Modeling Thermal Phenomena And Searching For New Thermally Induced Monitor Signals In Large Sale Gravitational Wave Detectors, Rupal Shashikant Amin

LSU Doctoral Dissertations

The Laser Interferometer Gravitational-wave Observatory (LIGO) array’s 4 km detectors have transitioned from an initial configuration (iLIGO) to an enhanced configuration (eLIGO) [1]. Both configurations relied on high circulating laser powers to achieve sensitivity goals between 150 Hz and 8 kHz. These power levels were sufficient to induce thermally driven focal affects in the primary optics. Since the detectors were designed to achieve maximum sensitivity when laser light was optimally coupled (mode matched) into the antenna, small deviations in focal parameters influenced performance. A laser based thermal compensation system (TCS) was installed for use in both configurations to counteract excessive …

Optimal Control And Nonlinear Programming, Qingxia Li

LSU Doctoral Dissertations

In this thesis, we have two distinct but related subjects: optimal control and nonlinear programming. In the first part of this thesis, we prove that the value function, propagated from initial or terminal costs, and constraints, in the form of a differential equation, satisfy a subgradient form of the Hamilton-Jacobi equation in which the Hamiltonian is measurable with respect to time. In the second part of this thesis, we first construct a concrete example to demonstrate conjugate duality theory in vector optimization as developed by Tanino. We also define the normal cones corresponding to Tanino's concept of the subgradient of …

Spatial Analyses Of Pedosphere Carbon Stock And Sequestration Potential In Louisiana's Watersheds, Biao Zhong

LSU Doctoral Dissertations

This dissertation research aimed to quantify current soil organic carbon (SOC) stocks across Louisiana’s landscape, examine the spatial relationships between SOC and terrain factors at the watershed and river basin scales, and predict SOC changes in surface soils during future climate change. Using Louisiana as an example, a spatially-explicit modeling framework was developed that is conducive to watershed-scale prediction of soil carbon stock and change. SOC densities at the watershed scale were estimated using the USDA NRCS Soil Geographic Database (STATSGO). Louisiana watersheds and National Land Cover Database (NLCD) were used to aggregate total soil carbon and estimate average soil …
