Investigations Into The Role Of Natural Organic Matter As An Interface Between Aquatic Organisms And Environmental Pollutants, Caroline Lillian Schneider Jan 2012

Investigations Into The Role Of Natural Organic Matter As An Interface Between Aquatic Organisms And Environmental Pollutants, Caroline Lillian Schneider

LSU Doctoral Dissertations

The impact of the continuous pollution of freshwater environments by multiple pollutants has not been well-studied. The goal of this research was to evaluate the toxicity of several modern pollutants in a model environment. The prokaryotic, unicellular blue-green algae Synechocystis WT6803 and the eukaryotic, multicellular Utterbackia imbecillis mussel larvae were studied along with Suwannee River natural organic matter (NOM). The toxicity response of the blue-green algae Synechocystis sp. was measured through changes in growth rates. The inorganic pollutant silver nanoparticles (0.044 μM) were toxic. Gold nanoparticles did not affect the growth rate. The addition of 15 mg/L NOM partially inhibited …

Mathematical Modeling In The High School Classroom, Selena Oswalt Jan 2012

Mathematical Modeling In The High School Classroom, Selena Oswalt

LSU Master's Theses

Mathematical modeling is the procedure whereby students apply mathematical concepts learned in class to new and unfamiliar situations. A modeling task is a mathematically-rich problem that engages students in mathematical thinking, drawing upon their previously learned knowledge and supporting their understanding of the mathematical concepts currently being covered. Modeling requires students to assign meaning to the mathematical concepts and to extend the concepts beyond rote learning. In order for students to be successful in a classroom that is centered around the idea of mathematical modeling, the students must be taught how to collaborate with other students, persevere through challenging problems, …

Design And Analysis Of Peer 2 Peer Operating System, Anudeep Meka Jan 2012

Design And Analysis Of Peer 2 Peer Operating System, Anudeep Meka

LSU Master's Theses

The peer to peer computing paradigm has become a popular paradigm for deploying distributed applications. Examples: Kadmelia, Chord, Skype, Kazaa, Big Table. Multiagent systems have become a dominant paradigm within AI for deploying reasoning and analytics applications. Such applications are compute-intensive. In disadvantaged networks the ad-hoc architecture is the most suitable one. Examples: military scenarios, disaster scenarios. We combine the paradigms of peer-to-peer computing, multiagent systems, cloud computing, and ad-hoc networks to create the new paradigm of ad-hoc peer-to-peer mobile agent cloud (APMA cloud) that can provide the computing power of a cloud in “disadvantaged” regions (e.g., through RF using …

An Alternative To Intellectual Property Theories Of Locke And Utilitarian Economics, Michael Morrissey Jan 2012

An Alternative To Intellectual Property Theories Of Locke And Utilitarian Economics, Michael Morrissey

LSU Master's Theses

In this paper, I examine two standard theories of intellectual property, voice criticisms of each theory from within their own perspectives, and offer an alternative approach to intellectual property. In the first chapter, I explicate Locke’s original property theory and provide a modern account of Lockean intellectual property as an extension of the original theory. I argue this extension is not compatible with Locke’s original thought on property rights. In the second chapter, I dissect the mainstream economic approach to intellectual property, an approach which employs utilitarianism to justify the intellectual property regime of first world, western nations. I argue …

Palladio's Religious Architecture In Venice, Katherine Fresina Jan 2012

Palladio's Religious Architecture In Venice, Katherine Fresina

LSU Master's Theses

This thesis focuses on the three churches designed by the Renaissance architect Andrea Palladio in Venice: San Francesco della Vigna, San Giorgio Maggiore, and Il Redentore. Separate chapters devoted to each of these buildings explore multiple issues, among them Palladio’s awareness of the city, its civic rituals, and architectural traditions; his sources of inspiration in the buildings of classical antiquity, especially ancient Roman baths and temple façades; his relationship to the architecture of the recent past, especially in Venice but also on the terraferma; and his ability to adapt his style to suit the requirements of private, public, and monastic …

Direction Of Mistuning, Magnitude Of Cent Deviation, And Timbre As Factors In Musicians' Pitch Discrimination In Simultaneous And Sequential Listening Conditions, Norman Alan Clark Jan 2012

Direction Of Mistuning, Magnitude Of Cent Deviation, And Timbre As Factors In Musicians' Pitch Discrimination In Simultaneous And Sequential Listening Conditions, Norman Alan Clark

LSU Doctoral Dissertations

The main purpose of this study was to investigate high school and college wind instrumentalists’ pitch discrimination when judging pitch pairs separated by 0, 5, 7.5, and 10 cents. Participants listened via headphones to a pre-recorded two section perception test; each section (one sequential and one simultaneous) containing 56 tone pairs. Each pair consisted of an in-tune reference tone followed by a test tone of the same pitch (B-flat4 or E4), which was either identical in tuning or altered to one of six mistunings. Tones also varied in timbre (square or sawtooth wave) with the reference and test tones being …

All Illnesses Are (Not) Created Equal: Reforming Federal Mental Health Insurance Law, Stacey A. Tovino Jan 2012

All Illnesses Are (Not) Created Equal: Reforming Federal Mental Health Insurance Law, Stacey A. Tovino

Scholarly Works

This Article is the second, and most important, installment in a three-part series that presents a comprehensive challenge to lingering legal distinctions between physical and mental illness. The basic impetus for this historical, medical, and legal project is a belief that there exists no rational or consistent method of distinguishing physical and mental illness in the context of health insurance law. The first installment in this series narrowly inquired as to whether a particular set of disorders, the postpartum mood disorders, are or should be classified as physical or mental illnesses in a range of health law contexts.* This second …

The “Ethical” Surplus Of The War On Illegal Immigration, Francis J. Mootz Iii, Leticia M. Saucedo Jan 2012

The “Ethical” Surplus Of The War On Illegal Immigration, Francis J. Mootz Iii, Leticia M. Saucedo

Scholarly Works

The Aristotelian philosopher, Gene Garver, suggests that rhetorical claims have an "ethical surplus" that extends beyond the specific claim being advanced at the moment. This follows from the fact that rhetoric includes not only logos, but also pathos and ethos. We adopt the thesis of "ethical surplus," but in a negative context. The "war on illegal immigration" has generated an ethical surplus that leads its promoters beyond the specific claim of securing borders against unlawful entry. After demonstrating that there is an express rhetoric of "war" used in connection with Arizona's adoption of recent anti-immigrant legislation, we explore …

Design Of An Automated Sensor Platform For The Calibration Of Aerial Liquid Dispersal Systems, Yin-Lin Chiu Jan 2012

Design Of An Automated Sensor Platform For The Calibration Of Aerial Liquid Dispersal Systems, Yin-Lin Chiu

LSU Master's Theses

Operation S.A.F.E workshops, commonly known as “fly-ins” help agricultural pilots “fine tune” their aircraft for aerial application work. During the fly-in several ancillary measurements are recorded; aircraft speed, aircraft spray release height, air temperature and relative humidity, wind speed and direction. These measurements are recorded by personnel operating the flight line with manually operated sensors. Some of the difficulties arise when the lack of personnel and or experience level hinders the ancillary measurement, or when equipment becomes difficult to repair and/or replace. The objectives of this project are to design two automated sensor platforms to aid data collection and analysis …

The Effects Of Oyster Harvest On Resident Oyster Reef Communities And Reef Structure In Coastal Louisiana Proper, Steven Lee Beck Jan 2012

The Effects Of Oyster Harvest On Resident Oyster Reef Communities And Reef Structure In Coastal Louisiana Proper, Steven Lee Beck

LSU Master's Theses

Harvest of the eastern oyster (Crassostrea virginica) is a primary contributor to oyster reef habitat disturbance in the northern Gulf of Mexico. The impacts of oyster dredging on reef substrate and resident fauna have not been thoroughly examined on the extensive sub-tidal oyster reefs of Louisiana. Several reef structure and resident community metrics were compared on unharvested and harvested reefs during the spring, summer, and fall of 2010. Unharvested reefs had higher amounts of oyster clusters, solid reef substrate, and more large oysters, while harvested reefs had higher amounts of loose shell, mixed shell/mud substrate, and elevated chlorophyll-a levels. Overall, …

Law, Politics, And Cost-Benefit Analysis, Daniel H. Cole Jan 2012

Law, Politics, And Cost-Benefit Analysis, Daniel H. Cole

Articles by Maurer Faculty

This Article explores the significant role cost–benefit analysis (CBA) plays in facilitating or impeding legislative and regulatory policy decisions. The Article centers around three case studies of CBAs the EPA prepared under three different presidents: (1) Clinton Administration changes to Clean Air Act air quality standards for ozone and particulate matter; (2) President Obama’s recent decision to suspend the EPA’s reconsideration of the Bush Administration’s air quality standard for ozone; and (3) the George W. Bush Administration’s “Clear Skies” legislative initiative. The first two case studies demonstrate, between them, how well-constructed CBAs can facilitate social-welfare-enhancing and impede welfare-reducing rules, even …

The Obama Administration’S Decision To Defend Constitutional Equality Rather Than The Defense Of Marriage Act, Dawn E. Johnsen Jan 2012

The Obama Administration’S Decision To Defend Constitutional Equality Rather Than The Defense Of Marriage Act, Dawn E. Johnsen

Articles by Maurer Faculty

When President Barack Obama announced his view that the Defense of Marriage Act1 (DOMA) violated the Fifth Amendment’s guarantee of equal protection,2 he joined a storied line of Presidents who have acted upon their own constitutional determinations in the absence of, and on rare occasion contrary to, those of the U.S. Supreme Court. How best to proceed in the face of a federal statute the President considers unconstitutional can involve complex judgments, as was true of the difficult decision to enforce but not defend DOMA. Ordinarily the Department of Justice should adhere to its tradition of defending statutes against constitutional …

Do Vcs Use Inside Rounds To Dilute Founders? Some Evidence From Silicon Valley, Brian Broughman, Jesse Fried Jan 2012

Do Vcs Use Inside Rounds To Dilute Founders? Some Evidence From Silicon Valley, Brian Broughman, Jesse Fried

Articles by Maurer Faculty

In the bank-borrower setting, a firm's existing lender may exploit its positional advantage to extract rents from the firm in subsequent financings. Analogously, a startup's existing venture capital investors (VCs) may dilute the founder through a follow-on financing from these same VCs (an “inside” round) at an artificially low valuation. Using a hand-collected dataset of Silicon Valley startup firms, we find little evidence that VCs use inside rounds to dilute founders. Instead, our findings suggest that inside rounds are generally used as “backstop financing” for startups that cannot attract new money, and these rounds are conducted at relatively high valuations …

Examining The Relationship Between The Exchange Rate, Foreign Direct Investment And Trade, Shanta Parajuli Jan 2012

Examining The Relationship Between The Exchange Rate, Foreign Direct Investment And Trade, Shanta Parajuli

LSU Doctoral Dissertations

Extensive research has been carried out on the relationships among foreign direct investment (FDI), exports, the exchange rate, and economic growth. However, these research findings are mixed and inconclusive. Therefore, further research and discussion are needed on this topic. This study focused on Mexico, since it is one of the major FDI recipient countries in Latin America and much of its trade is a result of its free trade agreements. This study examines the relationship between FDI, exports, and economic growth in the context of FDI from developed to developing countries (Mexico). The second chapter analyzes the relationship of FDI …

Reconfiguring Sex, Gender, And The Law Of Marriage, Deborah Widiss Jan 2012

Reconfiguring Sex, Gender, And The Law Of Marriage, Deborah Widiss

Articles by Maurer Faculty

This article brings together legal, historical, and social science research to analyze how couples allocate income-producing and domestic responsibilities. It develops a framework—what I call the marriage equation—that shows how sex-based classifications, (non-sex-specific) substantive marriage law, and gender norms interrelate to shape these choices. Constitutional decisions in the 1970s ended legal distinctions between the duties of husbands and wives but left largely in place both gender norms and substantive rights within marriage, tax, and benefits law that encourage specialization into breadwinning and caregiving roles. By permitting disaggregation of the marriage equation, the new reality of same-sex marriage can serve as …

Queer Utopian Geographies And Cold War Poetry, Brigitte Natalie Mccray Jan 2012

Queer Utopian Geographies And Cold War Poetry, Brigitte Natalie Mccray

LSU Doctoral Dissertations

Queer Utopian Geographies and Cold War Poetry intervenes in the general narrative about Cold War culture, made even more famous by such recent popular shows like Mad Men and Pan Am, that describes the era as a repressed society in desperate need of liberation. While indeed Cold War America was a time of paranoia and loyalty oaths, even before the Stonewall Riots of 1969 gay men and lesbians found subtle ways to resist popular media and government discourse that perpetuated the myth that the homosexual was the anti-citizen. A number of gay men and lesbians traveled extensively to escape this …

The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones Jan 2012

The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones

LSU Master's Theses

Spinosad is a relatively new insecticide with a unique mode of action that is being evaluated for control of larval mosquitoes. Whereas a number of toxicological studies have measured effects of spinosad on various mammals, fish, birds, and terrestrial arthropods, fewer studies have been conducted on the effects of spinosad on non-target aquatic insect species. Such studies are important as these species might be found in the same environments as mosquito larvae targeted for control. A neighborhood pond was surveyed to find a representative species of mosquito as well as other common aquatic insects with which to examine susceptibility to …

Law Student Knowledge Of Legal Interviewing: A Case Study Of Self-Evaluation Using Video Annotation, William Taggart Monroe Jan 2012

Law Student Knowledge Of Legal Interviewing: A Case Study Of Self-Evaluation Using Video Annotation, William Taggart Monroe

LSU Doctoral Dissertations

Video has long been used to support learner reflection in professional education programs in law, health, and education. Emerging video analysis tools offer learners the ability to highlight segments of video and focus their attention to specific moments or aspects of performance. These emerging tools afford opportunities for more systematic observation, analysis, and deliberate reflection on learner performance than was available previously. Expertise research has found that representative, rigorous tasks followed by immediate feedback and error correction constitute deliberate practice. Training environments that incorporate deliberate practice and emerging video annotation and analysis tools provide opportunities for learners pinpoint strengths and …

Using A Collaborative Inquiry Process And Data To Affect Curriculum In An Independent School, Sheri Lyn Pastor Goings Jan 2012

Using A Collaborative Inquiry Process And Data To Affect Curriculum In An Independent School, Sheri Lyn Pastor Goings

LSU Master's Theses

Literature clearly supports the use of data to support and drive school policy. Data can be immensely informative; however test scores are not the sole indicator of school effectiveness. To successfully implement a plan for data use, it is imperative to a provide climate of teacher buy-in and collaboration. Multiple sources of data should be considered collectively prior to making any judgment(s) about students, teachers, curriculum, or schools. Data use for effective decision-making is an on-going process that requires strategic planning and a long-term commitment. Over the past year, I have led the math department through a modified version of …

The Impact Of An Informal Science Learning Environment On The Environmentally Responsible Behavior Of Adults: A Case Study, Kathryn Ann March Jan 2012

The Impact Of An Informal Science Learning Environment On The Environmentally Responsible Behavior Of Adults: A Case Study, Kathryn Ann March

LSU Doctoral Dissertations

Since environmental education’s emergence in America, the field has been primarily focused on increasing environmental awareness, attitudes, knowledge, skills, and behavior. Yet the nation’s overall level of environmental literacy, especially with regard to the performance of environmentally responsible behaviors, continues to be low (Coyle, 2005). Unlike school-based education programs, which only reach a segment of the population, informal sites have the potential to influence learners of many ages and diverse backgrounds (NRC, 2009). Informal science learning environments (ISLEs) have been shown to provide personally meaningful learning experiences and have the potential to impact environmentally responsible decisions and actions (Falk, 2005). …

Educational Looping And Retention In The Middle School Setting, Mary Elizabeth Feighery Jan 2012

Educational Looping And Retention In The Middle School Setting, Mary Elizabeth Feighery

LSU Master's Theses

Educational looping is an educational method where teachers remain with the same core group of students over multiple academic years. The current research on this topic shows a strong positive correlation between the effects of looping and the growth of personal relationships between students and teachers, but neglects to examine the connection between looping and student educational growth. This paper explores the relationship between looping and academic gains, as well as between looping and retention of content material over time. This paper explores both the relationship between looping and academic gains and between looping and retention of content material, and …

Chemistry Faculty Publications and Presentations

The biosynthesis of GTP derived metabolites such as tetrahydrofolate (THF), biopterin (BH4), and the modified tRNA nucleosides queuosine (Q) and archaeosine (G+) relies on several enzymes of the Tunnel-fold superfamily. A subset of these proteins include the 6-pyruvoyl-tetrahydropterin (PTPS-II), PTPS-III, and PTPS-I homologs, all members of the COG0720 family, that have been previously shown to transform 7,8-dihydroneopterin triphosphate (H2NTP) into different products. PTPS-II catalyzes the formation of 6-pyruvoyltetrahydropterin in the BH4 pathway. PTPS-III catalyzes the formation of 6-hydroxylmethyl-7,8-dihydropterin in the THF pathway. PTPS-I catalyzes the formation of 6-carboxy-5,6,7,8-tetrahydropterin in the Q pathway. Genes of these …

Opportunistic Lookahead Routing Procedure For Delay Tolerant Networks, Priyanka Rotti Jan 2012

Opportunistic Lookahead Routing Procedure For Delay Tolerant Networks, Priyanka Rotti

LSU Master's Theses

Delay Tolerant Networks are wireless networks that have sporadic network connectivity, thus rendering the existence of instantaneous end-to-end paths from a source to a destination difficult or impossible. Hence, in such networks, message delivery relies heavily on the store-and-forward paradigm to route messages. However, limited knowledge of the contact times between the nodes poses a big challenge to effective forwarding of messages. In this thesis, we discuss several aspects of routing in DTNs and present one algorithm and three variants for addressing the routing problem in DTNs: (i) the Look-ahead Protocol, in which the forwarding decision at each node to …

Advising Terrorism: Material Support, Safe Harbors, And Freedom Of Speech, Peter Margulies Jan 2012

Advising Terrorism: Material Support, Safe Harbors, And Freedom Of Speech, Peter Margulies

UC Law Journal

Ever since Brandenburg v. Ohio, departures from content neutrality under the First Amendment have received strict scrutiny. However, in Holder v. Humanitarian Law Project (“HLP”), the Supreme Court decided that the perils of content regulation were less pressing than was the need to curb the human capital of groups, such as Hamas, designated as foreign terrorist organizations (“DFTOs”). As a result, the Court upheld a statute that bars “material support” of terrorist organizations, ruling that the statute bars speech coordinated with DFTOs, including training in negotiation or the use of international law. Some commentators have labeled HLP as heralding a …

Role Of Herpes Simplex Type I Glycoproteins In Entry And Cell-Cell Fusion, Sona Chowdhury Jan 2012

Role Of Herpes Simplex Type I Glycoproteins In Entry And Cell-Cell Fusion, Sona Chowdhury

LSU Doctoral Dissertations

Herpes simplex virus type I (HSV-1) is a neurotropic virus that infects primarily mucocutaneous epithelial cells and nervous tissue. Membrane fusion is an important aspect of the HSV-1 lifecycle, that occurs during viral entry (virus-cell fusion), viral spread (cell-to-cell fusion), as well as, during virion morphogenesis (assembly and egress). These membrane fusion steps involve complex interactions between multiple viral glycoproteins and cellular receptors. HSV-1 glycoprotein B (gB) is necessary but not sufficient for membrane fusion events. Despite the fact, that the majority of known hypermorphic mutations which cause extensive virus-induced cell fusion occur within glycoprotein K (gK); yet the role …

Note – Playing Hot Potato In The Market: The Ninth Circuit’S Better Approach To Calculating Loss For Securities Fraud Sentencing, Erica Connolly Jan 2012

Note – Playing Hot Potato In The Market: The Ninth Circuit’S Better Approach To Calculating Loss For Securities Fraud Sentencing, Erica Connolly

UC Law Journal

In United States v. Berger, the Court of Appeals for the Ninth Circuit departed from the Second and Fifth Circuits regarding the standard required to determine loss for securities fraud under the Federal Sentencing Guidelines. Unlike its sister circuits, the Ninth Circuit held that the Supreme Court’s reasoning in Dura Pharmaceuticals, Inc. v. Broudo for loss causation in civil securities fraud actions did not apply to the criminal sentencing context. Instead, the Ninth Circuit endorsed price inflation, which was rejected in Dura Pharmaceuticals, as a method of determining loss under the Guidelines. This Note examines the circuits’ decisions in light …

Regional Effects Of Monetary Policy, Taehee Han Jan 2012

Regional Effects Of Monetary Policy, Taehee Han

LSU Doctoral Dissertations

A key element of this dissertation is the examination of the regional and state level effects of monetary policy. The first essay compares two broad approaches to identifying the monetary policy shocks that are used to estimate the regional effects of monetary policy. One approach that has been used in the previous literature assumes that monetary policymakers respond to shocks to regional personal income but do not respond directly to shocks to national income. A second general approach assumes that monetary policymakers respond to shocks to national income but do not respond directly to region-specific income shocks. This assumption is …
