Substrate-Borne Marking In The Parasitoid Wasp Urolepis Rufipes (Hymenoptera: Pteromalidae), J. L. Cooper, Bethia H. King

Faculty Articles, Papers, and Other Scholarship

Many animals use pheromone marking as a way to identify their territory or other resources. Among insects, substrate-borne marking is frequently reported for females, which in many species make marks containing oviposition deterring pheromone, which other females avoid. However, there are fewer reports of substrate-borne marking for males. Here marking in males of the parasitoid wasp Urolepis rufipes (Ashmead) is described. The conditions under which males mark and whether males and females respond to the males’ marks were examined using behavioral observations. Males marked by dragging the tips of their abdomens across a substrate. They marked much more after mating …

Key Aspects For Lrfd Implementation For Driven Pile Capacity By Dynamic Methods, Natalie R. Ehrlich

Civil and Environmental Engineering Master's Project Reports

Inputs and interpretation procedures for pile wave equation analysis, which correlates measured field dynamic driving response to axial pile static capacity, are highly dependent on site-specific soil conditions and field practices. The 6^th Edition of the AASHTO LRFD Bridge Design Specifications provide generalized guidelines for pile design, but do not account for variability in region-specific soils and field practices. A comprehensive literature review of region-specific resistance factor recalibration efforts across the U.S. has given insight into the range of implementation issues encountered, especially the key decisions around choosing a restrike (BOR), along with measures of efficiency and treatment of …

We used survey data conducted at the establishments regarding respondents' travel characteristics from a previous study, …

Three Year Assessment Of Nearshore Crude Oil Contamination In The Gulf Of Mexico Using Gulf Menhaden (Brevoortia Patronus) As An Indicator Species: Menhaden Watch, Gregory Michael Olson

LSU Doctoral Dissertations

Approximately 4.9 million barrels of crude oil along with natural gas were released into the Gulf of Mexico (GoM) from April to July 2010 (Deepwater Horizon, DWH, spill). Impacts of this magnitude seldom occur in the GoM (Ixtoc I was the last spill close to this magnitude occurring in 1979), and one cannot predict when they will happen. Major constituents of concern found in crude oil are Polycyclic Aromatic Hydrocarbons (PAHs), which often have low volatility that allows for prolonged existence in the environment. PAHs are compounds of concern according to the United States Environmental Protection Agency (USEPA), with one …

Stress, Anxiety Symptomology, And The Need For Student Support Services For University Freshmen Of First-Generation Status, Low-Ses Backgrounds, And Those Registered With Disabilities, Kelly Dale Allison

LSU Master's Theses

Three populations of concern for professional social workers in higher educational settings include first-generation college students (FGCSs), students from low socio-economic (low-SES) backgrounds, and students with disabilities. As the national demand for degrees in higher education rises both socially and economically, the push for young adults’ postsecondary success becomes increasingly crucial. In college and university settings, a significant portion of students may be classified as FGCSs, low-SES, or may be registered with a disability. Examining these vulnerable populations within higher education settings, particularly regarding stress and anxiety symptomology, can help social workers recognize the social, developmental, and academic inhibitions that …

The False Idealization Of Heteronormativity And The Repression Of Queerness, Catherine Lynn Thurmond

LSU Master's Theses

In this thesis, entitled “The False Idealization of Heteronormativity and the Repression of Queerness,” I examine heteronormativity as a social structure that is idealized over, and against, queerness. In the first chapter, I define heteronormativity and queerness. “Heteronormativity,” here, is simply a set of standards that dictate what one must do with their gender and sexuality, such as having sexual relations with the opposite sex, getting married, or having children. Heteronormativity is visible, validated, and normalized in society. Conversely, “queerness” refers to the social structures that dictate what one must not do with their gender and sexuality. Thus, queerness is …

Insights Into 5-Lipoxygenase Active Site And Catalysis, Sunayana Mitra

LSU Doctoral Dissertations

Leukotrienes are potent immune-modulatory compounds involved in the inflammatory response. 5-Lipoxygenase (5-LOX) is the enzyme that catalyzes the production of Leukotriene A4 (LTA4), which is further metabolized to pro- and anti-inflammatory compounds derived from the substrate Arachidonic Acid (AA), a polyunsaturated fatty acid. The crystal structure of a stabilized form of 5-LOX has been recently reported (Gilbert, Bartlett et al. 2011). However, the structure does not reveal the mode of substrate entry or recognition. The first step in the enzymatic reaction involves the removal of a hydrogen from the central carbon of a pentadiene present in the substrate. It is …

Challenges Towards Structural Integrity And Performance Improvement Of Welded Structures, Mohammad Washim Dewan

Welding is a fabrication process that joint materials, is extensively utilized in almost every field of metal constructions. Heterogeneity in mechanical properties, metallurgical and geometrical defects, post-weld residual stresses and distortion due to non-linear welding processes are prime concerns for performance reduction and failures of welded structures. Consequently, structural integrity analysis and performance improvement of weld joints are important issues that must be considered for structural safety and durability under loading. In this study, an extensive experimental program and analysis were undertaken on the challenges towards structural integrity analysis and performance improvement of different welded joints. Two widely used welding …

Non-Marital Families And (Or After?) Marriage Equality, Deborah A. Widiss

Articles by Maurer Faculty

If, as is widely expected, the Supreme Court soon holds that bans on same-sex marriage are unconstitutional, it is almost certain that the decision will rely heavily on the Court’s reasoning in United States v. Windsor. I strongly support marriage equality. However, a decision that amplifies Windsor’s conception of the harm caused by exclusionary marriage rules could set back efforts to secure legal recognition of, and respect for, non-marital families. That is, Windsor rectified a deep inequality in the law—that same-sex marriages were categorically denied federal recognition—but in so doing it embraced a traditional understanding of marriage as superior to …

Griggs At Midlife, Deborah A. Widiss

Articles by Maurer Faculty

Griggs v. Duke Power, the Supreme Court case that held that policies that disproportionately harm minority employees can violate federal employment discrimination law even without evidence of “intentional” discrimination, recently turned forty. Griggs is generally celebrated as a landmark decision, but disparate impact’s current relevance (and its constitutionality) is hotly debated. Robert Belton’s The Crusade for Equality in the Workplace offers a rich and detailed history of the strategic choices that led to the plaintiffs’ victory in Griggs. This Review uses Belton’s history as a jumping off point to consider the contemporary importance of disparate impact in efforts to challenge …

Book Review. Reviving Fiscal Citizenship, Ajay K. Mehrotra

Articles by Maurer Faculty

In recent years, numerous lawmakers, policy analysts, and scholars have been decrying the many defects of the present U.S. income tax system. Few have attempted to defend our return-based mass income tax. This essay reviews Learning to Love Form 1040, Lawrence Zelenak’s stirring and persuasive defense of a simplified version of our present federal income tax system. In contrast to the conventional economic critiques, Zelenak explores the underappreciated social, cultural, and political benefits of a return-based, mass income tax. Chief among these, he argues, is the existing regime’s potential to raise the tax consciousness of the average citizen and to …

The Viability Of Enterprise Jurisdiction: A Case Study Of The Big Four Accounting Firms, Hannah L. Buxbaum

Articles by Maurer Faculty

One of the boundaries that U.S. courts must observe as they adjudicate regulatory disputes is the limit on their own jurisdictional authority -authority that is measured at the level of the particular forum state. Confronting the expansion of U.S. business activity from the local to the national scale during the second half of the twentieth century, courts consciously broadened jurisdictional standards to address the expanded activities of nationwide corporate groups. Today, by contrast, as the economy continues to expand from the national to the transnational scale, the U.S. Supreme Court has begun a retrenchment. In cases decided during the past …

Interpretation Of Geochemical Signatures From Modern Carbonate Springs To The Rock Record, Benjamin Maas

LSU Doctoral Dissertations

Despite the importance of carbonate aquifers as reservoirs of oil, of water, and of carbon dioxide, questions remain about the diagenetic processes that enhance porosity and permeability. Some of the questions are: 1) what are the water-rock interactions that control the geochemistry of spring waters; 2) are the geochemical signatures of saline-fresh water mixing zones preserved in the carbonate rock record; and 3) how much carbon dioxide outgases along spring runs? To address these questions, two field sites, one in Oklahoma (the site of an active saline-fresh water mixing zone) and the other in Colorado, the location of a former …

Output Consensus Control For Heterogeneous Multi-Agent Systems, Abhishek Pandey

LSU Doctoral Dissertations

We study distributed output feedback control of a heterogeneous multi-agent system (MAS), consisting of N different continuous-time linear dynamical systems. For achieving output consensus, a virtual reference model is assumed to generate the desired trajectory for which the MAS is required to track and synchronize. A full information (FI) protocol is assumed for consensus control. This protocol includes information exchange with the feed-forward signals. In this dissertation we study two different kinds of consensus problems. First, we study the consensus control over the topology involving time delays and prove that consensus is independent of delay lengths. Second, we study the …

Thomas Davis, The Nation, And Songs Of Irish Nationalism, Timothy Mason Love

LSU Doctoral Dissertations

Thomas Davis was a significant figure in the flourishing movement of cultural nationalism in mid-nineteenth-century Ireland. A cofounder of _The Nation_, Davis used the journal’s pages as a medium through which to promote a nationalist vision for Ireland distinctive for its nonsectarian appeal. Along with impassioned editorial prose, Davis employed poetry and song to carry his message to the public. “Young Ireland,” as Davis and his colleagues became known, focused their efforts especially on the traditional Irish song, elevating it as a symbol for their cultural heritage while harnessing its emotional power to strengthen their political cause. The songs printed …

Study Of Factors Affecting Growth And Development Of Narrow Brown Leaf Spot Of Rice Caused By Cercospora Janseana (Racib.) O. Const., Kirandeep Kaur Mani

LSU Doctoral Dissertations

Studies evaluated the effects of planting date, cultivar susceptibility, fungicide application timing, nitrogen management, and tillage practices on the severity of narrow brown leaf spot of rice (NBLS) caused by Cercospora janseana. All factors evaluated affected NBLS severity. The mid-April planted rice had less NBLS as compared to mid-May, late planted rice. Propiconazole fungicide (Tilt) application at panicle initiation or early boot stage was found equally effective in terms of disease reduction in mid-April planting while panicle initiation stage was the best time to apply fungicide in the late planting (mid-May). Early onset and higher severity of NBLS was observed …

Saccharomyces Cerevisiae Tel1 & Tel2 Role In Dna Double-Strand Break Repairs, Tommy Nhan Trieu

LSU Master's Theses

Genomic DNA is constantly in danger of being damaged by endogenous cellular processes and exogenous agents. Eukaryotes have mechanisms, collectively termed the DNA damage response, that detect and repair DNA damage. After a double-stranded break occurs, protein complexes are recruited to the break site to promote resection. Two main protein kinases involved in DNA repair are the Tel1 and Mec1 proteins. Recent studies have found that the Tel2 protein binds to both the Tel1 and Mec1 proteins and a point mutation of TEL2 on the 129th amino acid disrupts this interaction. Since both of the Tel1 and Mec1 proteins are …

Labor Law 2.0: The Impact Of New Information Technology On The Employment Relationship And The Relevance Of The Nlra, Kenneth G. Dau-Schmidt

Articles by Maurer Faculty

The NLRA system of collective bargaining was born during the industrial age of the early twentieth century. As a result, key terms in the statute such as "employee," "employer," and "appropriate bargaining unit" were first interpreted in the context of long-term employment and large vertically integrated firms that dominated this era. Beginning in the late 1970s, the new information technology wrought a revolution in the organization of production increasing short-term contingent employment and the organization of firms horizontally in trading and subcontracting relationships across the globe. To maintain the relevance of collective bargaining to the modern workplace, the interpretation of …

From With-In The Black Diamond: (Black Diamond) autoethnographically explores the lived experiences of a Black male who navigates his way through a predominately white higher education institutions while existing within marginalized spaces related to his gender, ethnicity, and identity. Black Diamond uses epistolary writing techniques to explore question research question: 1. How has a Black Gay male graduate student studying Higher Education negotiated his way to and through predominately white higher education institutions? In order to support the answering of this question I will argue that the most influential reasons higher education literature rarely addresses controversial topics related to GLBTQ …

Juice Processing Effects On Small Scale Not From Concentrate Rabbiteye Blueberry Juice Production: The Evaluation Of Juice Recovery And Identification Of Anthocyanins And Anthocyanidins Through Processing Steps, Rebecca Elaine Stein-Chisholm

LSU Master's Theses

The order and combination of juicing steps can change a blueberry’s bioactive phytochemicals and effect juice recovery. In addition to physical treatments such as pressing, recovery is also affected by heat and enzymes steps. Not optimizing juicing methods affect juice quality and leave many bioactive components in the press cake. To evaluate pre-press treatments, southern highbush and rabbiteye blueberries were individually pressed in a bench top press at varying temperatures. The temperature treatments included fresh, thawed, frozen and heating to 95 °C. Two pectinase enzymes, Rohapect 10L and Pectinex BEXXL, were individually used to assess impact on juice extraction.
