The Impact Of Predator-Prey Relationships On The Formation Of Harmful Algal Blooms In Heterosigma Akashiwo, Elizabeth L. Harvey

Open Access Dissertations

Heterotrophic protists are the primary grazers of phytoplankton in the marine environment, and changes in the rates of consumption will influence phytoplankton abundance, community composition, and ecological function. The objective of this research was to investigate the influence of predators on the formation and promotion of harmful algal blooms (HABs), specifically blooms of the toxic raphidophyte alga, Heterosigma akashiwo. To observe microscopic predator-prey interactions and their macroscopic distributions, video and image analysis were used to simultaneously quantify population distributions and individual 3D movements of both protistan predators and prey cells in laboratory tanks with realistic salinity structures. In behavioral experiments, …

Synthesis Of The Western Hemisphere Of Theonellamide C, Saroj Yadav

LSU Doctoral Dissertations

Theonellamides A-F were isolated from Theonella swinhoei by Fusetani and co-workers. Despite considerable synthetic effort to produce theonellamide F by the Shioiri group in the early 1990’s, the total synthesis of a theonellamide has yet to be reported. We report herein our efforts toward some of the required amino acid residues and construction of the western ring of theonellamide C. We describe the synthesis of an uncoded amino acid, (2S,4R)-ɣ-hydroxy-α-amino adipic acid (Ahad), a building block for theonellamide C. We initially investigated the Corey-Lygo method for the catalytic asymmetric generation of the Cα stereocenter. Unfortunately, the alkylation of glycine benzophenone …

Analysis Of Protein Aggregates And Synthetic Nanoparticles Using Capillary Electrophoresis With Light Scattering And Fluorescence Detection, Suresh Chandra Regmi

LSU Doctoral Dissertations

The goal of the research presented in this dissertation is to develop capillary electrophoresis (CE) based analysis techniques for the characterization of individual particles including amyloid beta (Aâ) peptide aggregates and to apply these methods to study the aggregation of Aâ peptides. Protein self-assembly into ordered aggregates is a common and important process in normal biological function, but this process is also involved in several diseases. Amyloid beta peptide aggregation is linked to Alzheimer’s disease. Thioflavin T (ThT) has been used as a fluorescent probe for the detection of Aâ aggregation. Based on previous observations of false positive fluorescent signals …

Fishable Waters, Catherine A. O'Neill

Faculty Articles

This article discusses the implications of tribes' treaty-secured rights to take fish for current efforts to set water quality standards in Washington and elsewhere in the Pacific Northwest. Among other things, this article considers the impact of ongoing treaty rights litigation, including the landmark ruling in the "culverts" case handed down by the Western District of Washington in March, 2013. Although this article focuses on agency decision making in the tribal context, it recounts a debate that has often been framed by arguments that are familiar from more general discussions of risk-based regulation. In fact, these generic arguments are often …

Procedural Due Process In The Expulsion Of Aliens Under International, United States, And European Union Law: A Comparative Analysis, Won Kidane

Faculty Articles

Liberal democracies aspire to respect minimum standards of individual liberty and due process to all. They structurally limit their powers with respect to how they treat all persons-including noncitizens, also known as "aliens." Nonetheless, the exact scope and nature of the limitations imposed by international and domestic legal regimes for the expulsion of noncitizens still remains uncertain and is in a constant state of evolution in multiple directions. Indeed, a mix of situational progression and regression characterizes these regimes. The proper balance between personal liberty, due process, and equal protection on the one hand-and security, economic and related governmental and …

Morally Injurious Symptomatology: A Qualitative Examination Of The Nvvrs, Douglas Stewart Kraus

Theses and Dissertations

As with all psychological constructs in their infancy, it is important to operationalize a definition as part of the construct validation process. As a phenomenon that continues to gain recognition amongst the psychological community, Moral Injury (MI) is no different. Although Litz et al. (2009) introduced and defined MI as the "psychological, biological, spiritual, behavioral, and social impact of perpetrating, failing to prevent, or bearing witness to acts that transgress deeply held more beliefs and expectations," Drescher et al. (2011) found that a similar working definition was "inadequate" and lacked clarity according to trauma experts' opinion. The following exploratory, qualitative …

Motivation Towards Learning Perceived In Socratic Seminar Versus Traditional Lecture, Benjamin N. Roberson

Theses and Dissertations

As discussed in past literature, high school students often lack motivation towards learning (Crow, 2007; Lumsden, 1995). This lack of motivation interferes with student learning (Lumsden,1995; Vansteenkiste, Simons, Lens, Soenens, & Matos, 2005). At the middle school and collegiate level, Socratic Seminar is seen to provide motivation towards learning in students (Copeland, 2005; Mee, 2000; Strong, 1996); however, there is a need for research on student motivation as a result of Socratic Seminar at the high school level. The purpose of this study is to identify the extent to which, if any, differences exist in student motivation towards learning among …

Comparative Analysis Of Corporate Culture In A Multinational Organization, Don G. Gilman

Theses and Dissertations

This study built upon the Project GLOBE (House, Hanges, Javidan, Dorfman, & Gupta, 2004) analysis by using a Web-based version of the GLOBE Questionnaire in order to examine the extent to which the cultural values and practices of middle managers in a multinational organization vary depending on (a) their cultural background and the region in which they work, (b) whether they were a member of a recently acquired company, and (c) the number of years employed by the multinational organization. Multinational organizations face the unique challenge of operating in societies that have different sets of cultural norms, expectations, beliefs, and …

New Site Administrators' Perceptions Of Their Role In School Community Partnerships, Denise Calvert-Bertrand

Theses and Dissertations

This study's purpose was to investigate new site administrators' perceptions of the term community involvement, of their role to engage the local community members as partners in their school, their preparation and support to work with their communities, and their challenges on-the-job with community engagement. This study also examined new site administrators' perceptions and needs to better understand what tools are necessary to help them create thriving community partnerships. Thirty new site administrators across 4 counties of Southern California participated in a semi-structured 45-minute interview. All were employed less than 4 years and represented the gender, age and ethnic diversity …

Signs And Symptoms Of Moral Injury In Female Vietnam Veterans: A Qualitative Examination Of The Nvvrs, Alison H. Conway

Theses and Dissertations

It is well-known that war veterans experience long-lasting physical and psychological injuries following their deployment, and recent studies have proposed the construct of moral injury (MI) to explain the moral and spiritual effects of war on individuals. Litz et al. (2009) defined MI as "perpetrating, failing to prevent, or bearing witness to acts that transgress deeply held moral beliefs and expectations" (p. 6), and Drescher et al. (2011) interviewed trauma experts to identify types of events that could create MI and the lasting sequelae of these events. Vargas et al. (2013) provided validation of MI by examining male Vietnam veterans' …

The Effects Of Public School Music Education Programs On Leadership In The Workplace, Lawrence Michael Jacobson

Theses and Dissertations

Throughout history, music has consistently played a large role in helping to define the social, historical, and cultural awareness in human society. For children and young adults who have actively studied music in public school music education programs, music has enhanced their self-discipline, self-esteem, and creativity. Over the past 20 years, there have been several examples of how the business world has been turning to the music world for leadership and inspiration. There are, however, few studies that compare the effects of public school music education programs on leadership in the workplace. Researchers have primarily focused their studies on the …

Green Harms Of Green Projects, John Copeland Nagle

Journal Articles

This article describes the recent development of renewable energy to examine environmental law’s three contrasting approaches to the green harms of green projects. Sometimes the law allows the green benefit regardless of the green harm. Sometimes the law prohibits the green harm regardless of the green benefit. And sometimes the law allows a balancing of all of the harms and benefits, green or not. Given these options, I argue that the law should not ignore or understate green harms even if they are caused by green projects. There are some types of green harms that no benefit can justify. But …

Optimal Network Topologies And Resource Mappings For Heterogeneous Networks-On-Chip, Haera Chung

Dissertations and Theses

Communication has become a bottleneck for modern microprocessors and multi-core chips because metal wires don't scale. The problem becomes worse as the number of components increases and chips become bigger. Traditional Systems-on-Chips (SoCs) interconnect architectures are based on shared-bus communication, which can carry only one communication transaction at a time. This limits the communication bandwidth and scalability. Networks-on-Chip (NoC) were proposed as a promising solution for designing large and complex SoCs. The NoC paradigm provides better scalability and reusability for future SoCs, however, long-distance multi-hop communication through traditional metal wires suffers from both high latency and power consumption. A radical …

Stability Of Large Flocks: An Example, J. J. P. Veerman, F. M. Tangerman

Mathematics and Statistics Faculty Publications and Presentations

The movement of a flock with a single leader (and a directed path from it to every agent) can be stabilized. Nonetheless for large flocks perturbations in the movement of the leader may grow to a considerable size as they propagate throughout the flock and before they die out over time. As an example we consider a string of N+1 oscillators moving in the line. Each one `observes' the relative velocity and position of only its nearest neighbors. This information is then used to determine its own acceleration. Now we fix all parameters except the number of oscillators. We then …

Putting A Price On Whales To Save Them: What Do Morals Have To Do With It?, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

The author explores the moral implication of a proposal to create an international market in whale shares as an alternative to the dysfunctional International Whaling Commission. She finds the proposal amoral because whales, like humans, have an intrinsic right to life. Since this leaves whales vulnerable to whale hunting nations, she suggests that international environmental organizations might help a whale preservation norm emerge in whaling nations by using education and interventionist activities that focus on whaling’s cruelty to ultimately encourage the citizens and governments of those nations to change their self-image as whale eating cultures.

Relationships Between Childhood Trauma And Eating Pathology, Lindsay Katherine Crosby

Graduate Student Theses, Dissertations, & Professional Papers

Past research has demonstrated that a correlation exists between trauma exposure and eating disorder pathology. Specifically, sexual abuse has been implicated in the development of eating disorders, with particular attention focused on bulimia nervosa. However, the relationship between other types of trauma exposure and eating pathology has yet to be delineated, particularly how different types of trauma exposure may be related to disordered eating behaviors. The current study explored this relationship. Results showed while some experiences of trauma history predicted a proportion of the variance associated with disordered eating behaviors, others showed a positive but not significant correlation. Clinical implications, …

Alliance And Outcomes In Counseling Canadian Aboriginal Peoples, Sidney Shaw

This study evaluated predictors of outcome in counseling with Canadian Aboriginal peoples. Participants in the study included 373 Canadian Aboriginal clients receiving outpatient counseling at Calgary Counselling Centre in Alberta, Canada between October 2004 and November 2011. Outcome in this study was measured using the Outcome Questionnaire 45 (OQ-45) and predictor variables consisted of client demographics, counselor training level, and client ratings of the therapeutic alliance. The alliance was measured using the Session Rating Scale (SRS). Outcome variables, as measured by the OQ-45, were most often analyzed categorically and consisted of four different possible categories of change as measured from …

Effective Single-Parent Training Group Program: Three System Studies, Harold E. Briggs, Keva M. Miller, Edwin Roberto Orellana, Adam C. Briggs, Wendell H. Cox

School of Social Work Faculty Publications and Presentations

Objective: This study highlights Dr. Elsie Pinkston and colleagues’ research on the effectiveness of behavior parent training and examines the application of single-parent training group (SPG) programs to three parent–child dyads exposed to distressed family circumstances. Methods: Single-system evaluation designs were conducted with two single birth parents, one single foster parent, and each parent’s three respective children, in an effort to appraise the results of a SPG program.

Results: Two of the three parent–child dyads benefited from the SPG. Results suggested that there were changes in parent reinforcement and attention behaviors and children’s noncompliance behaviors.

Conclusion: Behavioral improvements in …

National Security Pedagogy: The Role Of Simulations, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

This article challenges the dominant pedagogical assumptions in the legal academy. It begins by briefly considering the state of the field of national security, noting the rapid expansion in employment and the breadth of related positions that have been created post-9/11. It considers, in the process, how the legal academy has, as an institutional matter, responded to the demand.

Part III examines traditional legal pedagogy, grounding the discussion in studies initiated by the American Bar Association, the Carnegie Foundation, and others. It suggests that using the law-writ-large as a starting point for those interested in national security law is a …

Toward A Jurisprudence Of Law, Peace, Justice, And A Tilt Toward Non-Violent And Empathic Means Of Human Problem Solving, Carrie Menkel-Meadow

Georgetown Law Faculty Publications and Other Works

In this essay the author sets out some questions about whether law can be made a site of encouraging more positive, peace seeking, non-violent, and pro-social behaviors. These questions derive from my own family history, as well as from my experience as a social and political activist, and also as a practicing lawyer and legal scholar. She begins in the introduction by setting out these questions in light of current conditions of domestic and international violence and some past considerations of categories of law. In the second section of this essay the author explains where her questions come from—her personal …

Reflections On Sexual Liberty And Equality: "Through Seneca Falls And Selma And Stonewall", Nan D. Hunter

Georgetown Law Faculty Publications and Other Works

This Essay uses the opportunity to examine Roe v. Wade forty years after it was decided and Lawrence v. Texas ten years after it was decided as a platform from which to analyze the status of the civil rights paradigm in American law. A comparison of the two decisions illustrates an important and new point about how civil rights law is deployed to achieve very different goals.

A Comprehensive Research Framework For Geographic Parthenogenesis In Whiptail Lizards (Genus Aspidoscelis), Adam Leland

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the most compelling topics in biology has been the ubiquity of sexual reproduction in living organisms. Because the ecological and evolutionary advantages of sex are well founded, those organisms that reproduce asexually remain enigmatic. Parthenogenesis, the clonal reproduction of an all-female species without the need for males, is a relatively common form of asexual reproduction in vertebrates, and has been subject of numerous academic investigations. Many parthenogenic organisms also share aspects of their geographic distributions, such as inhabiting higher latitudes, higher altitudes, islands or island-like habitats, xeric environments, and marginal, disturbed or ecotonal habitats relative to their sexual …

What Is Parenthood?: Contemporary Debates About The Family Introduction, Linda C. Mcclain, Daniel Cere

Faculty Scholarship

Extraordinary changes in patterns of family life – and family law – have dramatically altered the boundaries of parenthood and opened up numerous questions about debates. What is parenthood and why does it matter? How should society define, regulate, and support it? Despite this uncertainty, the intense focus on the definition and future of marriage diverts attention from parenthood. Demographic reports suggesting a shift away from marriage and toward alternative family forms also keep marriage in constant public view, obscuring the fact that disagreements about marriage are often grounded in deeper, conflicting convictions about parenthood. This book (as the posted …

Digit Ratios And Social Preferences: A Comment On Buser (2012), Pablo Brañas-Garza, Jaromir Kovarik

ESI Working Papers

Buser (2012) reports an association between the second-to-fourth digit ratio, a biomarker of the exposure to prenatal sex hormones, and behavior in several classic experimental games designed to elicit prosocial attitudes. His subjects self-report whether they have shorter, equal, or larger ring than index nger. We argue that this elicitation method is inappropriate. It generates a poor proxy for the digit ratio as it su ers from measurement errors. As a result, using this variable in the regression analysis may lead to inconsistent estimates.

Improved Synthesis Of 3-Aryl-Isoxazoles As Intermediates For Novel G-Quadruplex Binding Anti-Tumor Agents, Matthew Jacob Weaver

Graduate Student Theses, Dissertations, & Professional Papers

As a promising new target for chemotherapy G-quadruplexes (G4) have drawn great interest from the scientific community. Current chemotherapeutic agents exhibit broad toxicity to patients; G4 has the potential to be selectively targeted by novel chemotherapeutic agents that exhibit toxicity specific towards cancer cells. Anthracenyl isoxazolyl amides (AIMs) have shown potent anti-tumor activity and have evidence to support them as G4 binding molecules. Studies of the AIMs’ unique mechanism of action require an efficient synthesis of target molecules. For our system, methods traditionally used to synthesize isoxazoles were inefficient and gave poor yields. A critical comparison of methods to prepare …

Comparison Of Wild-Domestic Sheep Interaction Policies In Bighorn Disease Outbreak Locations In The Continental U.S., 1990-2010, Tristan Howard

Graduate Student Theses, Dissertations, & Professional Papers

For over 100 years, disease has significantly limited bighorn sheep (Ovis canadensis) in the western U.S. Interaction with domestic sheep (Ovis aries) has been a primary cause of fatal bighorn disease (typically pneumonia), which has severely reduced or eliminated entire populations. Various wild-domestic sheep interaction policies exist to address the disease problem. In this analysis, six case study locations are compared and analyzed in an effort to evaluate policy efficacy. Locations examined and their bighorn die-off dates include: the Tobin Range, NV (1991); Aldrich Mountain, OR (1991); the Highland/Pioneer Mountains, MT (1994-1995); the Tarryall/Kenosha Mountains, CO (1997-2000); the Hays Canyon …

Two Conflicts In Context: Lessons From The Schiavo And Bland Cases And The Role Of Best Interests Analysis In The United Kingdom, Barbara A. Noah

Faculty Scholarship

This Essay considers the different approaches to end of life decision making for incapacitated patients in the United States and in the United Kingdom. In the United States, individual patient autonomy is the primary guidepost for making end of life decisions for incapacitated patients. In the United Kingdom, patient preference is openly and deliberately supplemented with a careful consideration of the patient’s best interest. To contrast the two approaches, the Essay focuses on two cases involving patients in permanent vegetative states (PVS) for whom little was known about their respective individual preferences, and it analyzes the differences in conceptualization and …

An Ice-Core Pollen Record Showing Vegetation Response To Late-Glacial And Holocene Climate Changes At Nevado Sajama, Bolivia, C. A. Reese, K. B. Liu, L. G. Thompson

Faculty Publications

We present the results of pollen analysis performed on an ice core recovered from Nevado Sajama, Bolivia, dated to 25 ka BP. Low pollen concentrations from 25 to 15 ka BP are consistent with the scenario of an expanded ice cap surrounded by sparse vegetation and cold conditions on the Altiplano during the Last Glacial Maximum. After 15 ka BP, more pollen is present and percentages show vegetation response to climate fluctuations during the late Pleistocene. Initially, high concentrations of Poaceae pollen are replaced by Asteraceae pollen, suggesting the occurrence of dry conditions towards the end of the Bolling-Allerod/Guantiva interstadial. …

Prometheus Rebound: Diagnostics, Nature, And Mathematical Algorithms, Rebecca S. Eisenberg

Articles

The Supreme Court’s decision last Term in Mayo v. Prometheus left considerable uncertainty as to the boundaries of patentable subject matter for molecular diagnostic inventions. First, the Court took an expansive approach to what counts as an unpatentable natural law by applying that term to the relationship set forth in the challenged patent between a patient’s levels of a drug metabolite and the indication of a need to adjust the patient’s drug dosage. And second, in evaluating whether the patent claims add enough to this unpatentable natural law to be patent eligible, the Court did not consult precedents concerning the …
