Beyond Batterers: A Primary Prevention And Adult Learning Approach To Engage Well-Meaning Men To Prevent Violence Against Women, Lorett Sturgill Swank Jan 2015

Beyond Batterers: A Primary Prevention And Adult Learning Approach To Engage Well-Meaning Men To Prevent Violence Against Women, Lorett Sturgill Swank

LSU Doctoral Dissertations

This purpose of this research is to examine the critical issue of intimate partner violence and to explore a how non-battering “well-meaning men” can help to end this violence against women. Domestic violence has been primarily considered a women’s issue, and current efforts to prevent this violence have been led mostly by women. In spite of these efforts, violence against women still persists and “well-meaning men” have not been part of a proactive solution. This growing movement to engage men in preventing violence against women, empowers men to learn about and identify the issues that support a culture that tolerates …

A Quantitative Study Using Constructist Learning Activities To Connect Biology Concepts To Local Environmental Issues In A Non-Major Introductory College Biology Course, Michaelyn Broussard

LSU Doctoral Dissertations

Among the general population, there has continued to be a struggle to improve environmental literacy with the knowledge, attitude, and awareness of basic environmental issues locally and nationally. Despite efforts through many formal and informal programs, the result nationally has indicated little to no understanding of basic environmental issues (Coyle, 2005). Many educators such as Sobel (1996, 2004) and Louv (2005) have documented the lack of positive outdoor experiences or environmental behaviors. The purpose of this study was to incorporate local environmental examples through constructivist learning techniques within a general biology non-major course to promote an increase in environmental literacy …

Multiscale Modeling Of Particle Transport In Petroleum Reservoirs, Layne Bryan French Jan 2015

Multiscale Modeling Of Particle Transport In Petroleum Reservoirs, Layne Bryan French

LSU Master's Theses

Modeling subsurface particle transport and retention is important for many processes, including sand production, fines migration, and nanoparticle injection. In this study, a pore-scale particle plugging simulator is concurrently coupled with a streamline reservoir simulator to predict the behavior of particles in the subsurface. The coupled simulators march forward in time together. The automated communication between the two models enables the prediction of spatially and time dependent parameters that control the particle transport process. At each time step, the reservoir simulator provides the inlet velocity and particle concentration of the fluid suspension to the pore-scale model which outputs the permeability, …

Transmembrane Signaling And Conformational Regulation Of Integrin, Ping Hu Jan 2015

Transmembrane Signaling And Conformational Regulation Of Integrin, Ping Hu

LSU Doctoral Dissertations

Integrins are heterodimeric cell adhesion molecules that play an essential role in hemostasis, thrombosis, cell migration, and can transmit bidirectional signals. The inside-out activating signal triggers integrin conformational change, leading to high affinity for extracellular ligands. Binding of extracellular matrix ligands to integrins results in outside-in signaling that leads to formation of focal adhesion (FA) complex at the integrin cytoplasmic tails and activation of downstream signal pathways. Transmembrane/cytoplasmic domains are hypothesized to associate in resting integrins, whereas ligand binding and intracellular activating signals induce transmembrane domain separation. However, how this conformational change affects integrin outside-in signaling and whether the á …

The Stratal Architecture Of The False River Point Bar (Lower Mississippi River, La), Alexandra Lechnowskyj Jan 2015

The Stratal Architecture Of The False River Point Bar (Lower Mississippi River, La), Alexandra Lechnowskyj

LSU Master's Theses

The False River point bar system is located roughly thirty miles north of Baton Rouge, LA. It is an oxbow lake cut off from the Mississippi River, and represents a large-scale modern analogue to the ancient systems of northeastern Alberta, Canada, specifically those of the Athabasca Oils Sands. While previous work has been done regarding the general architecture of a point bar, there is still omplexity associated with larger scale systems, as studies have been mostly based on small and medium-scale examples. Examination of the point bar was done through a combination of coring and geophysical logging, followed by software …

Analysis Of Nonlinear Dispersive Model Equations, Jacob Grey Jan 2015

Analysis Of Nonlinear Dispersive Model Equations, Jacob Grey

LSU Doctoral Dissertations

In this work we begin with a brief survey of the classical fluid dynamics problem of water waves, and then proceed to derive well known evolution equations via a Hamiltonian Variational approach. This method was first introduced in the seminal work of Walter Craig, et al. \cite{CG}. The distinguishing feature of this scheme is that the Dirichlet-Neumann operator of the fluid domain appears explicitly in the Hamiltonian. In the second and third chapters, we utilize the Hamiltonian perturbation theory introduced in \cite{CG} to derive the Benjamin-Bona-Mahony (BBM) and Benjamin-Bona-Mahony-Kadomtsev-Petviashvili (BBM-KP)equations. Finally, we briefly review the existence theory for their corresponding …

Extreme Tolerance And Developmental Buffering Of Uv-C Induced Dna Damage In Embryos Of The Annual Killifish Austrofundulus Limnaeus, Josiah Tad Wagner, Jason E. Podrabsky Jan 2015

Extreme Tolerance And Developmental Buffering Of Uv-C Induced Dna Damage In Embryos Of The Annual Killifish Austrofundulus Limnaeus, Josiah Tad Wagner, Jason E. Podrabsky

Biology Faculty Publications and Presentations

Free-living aquatic embryos are often at risk of exposure to ultraviolet radiation (UV-R). Successful completion of embryonic development depends on efficient removal of DNA lesions, and thus many aquatic embryos have mechanisms to reverse DNA lesions induced by UV-R. However, little is known of how embryos that are able to enter embryonic dormancy may respond to UV-R exposure and subsequent DNA damage. Embryos of the annual killifish Austrofundulus limnaeus are unique among vertebrates because their normal embryonic development includes (1) a complete dispersion of embryonic blastomeres prior to formation of the definitive embryonic axis, and (2) entry into a state …

Catalysts For The Positional Isomerization Of Internal, Long-Chain Olefins, James Edward Bruno

LSU Doctoral Dissertations

Double-bond isomerization of internal C16-C18 olefins is a necessary step in the production of paper sizing agents. In this work, the properties that enable long-lasting solid acid catalysts (both commercial and lab-synthesized) were identified, the efficacy of regenerated solid acid catalysts was tested, and the feasibility of organometallic chain-walking catalysts (both homogeneous and polymer-supported) for olefin isomerization was evaluated. Hexadecene isomerization was investigated using perfluorinated ion exchange resins (Nafion®) supported on SiO2 or Al2O3, sulfonated poly(styrene-co-divinylbenzene) resins (PS-DVBs), tungstated zirconias, and acidic zeolites. Selected catalysts underwent lifetime studies. Oversulfonated PS-DVBs (e.g., Amberlyst 35) were reasonably selective with long lifetimes, only …

On An Effective Submodeling Procedure For Stresses Determined With Finite Element Analysis, Ajay Ashok Kardak Jan 2015

On An Effective Submodeling Procedure For Stresses Determined With Finite Element Analysis, Ajay Ashok Kardak

LSU Doctoral Dissertations

Submodeling can enable stress analysts using finite elements to focus analysis on a subregion containing the stress concentration of interest, with consequent computational savings. Such benefits are only truly realized if the boundary conditions on the edges of the subregion that were originally contained within the global region are sufficiently accurate. These boundary conditions are drawn from initial global finite element analysis (FEA), and consequently themselves have errors that in turn lead to errors in the stresses sought. When these last boundary-condition errors are controlled, and the discretization errors incurred by the FEA of ensuing submodels are also controlled, submodeling …

Classification In The Presence Of Ordered Classes And Weighted Evaluative Attributes, Forrest Justin Osterman Jan 2015

Classification In The Presence Of Ordered Classes And Weighted Evaluative Attributes, Forrest Justin Osterman

LSU Doctoral Dissertations

We are interested in an important family of problems in the interface of the Multi-Attribute Decision-Making and Data Mining fields. This is a special case of the general classification problem, in which records describing entities of interest have been expressed in terms of a number of evaluative attributes. These attributes are associated with weights of importance, and both the data and the classes are ordinal. Our goal is to use historical records and the corresponding decisions to best estimate the class values of new data points in a way consistent with prior classification decisions, without knowledge of the weights of …

Does The Pcaob Inspection Have An Effect On Audit Fees And Audit Quality?, Elizabeth Schwartzhoff Johnson Jan 2015

Does The Pcaob Inspection Have An Effect On Audit Fees And Audit Quality?, Elizabeth Schwartzhoff Johnson

LSU Doctoral Dissertations

I investigate the effects of the issuance of the PCAOB Part II report on audit fees and audit quality. The PCAOB replaced the peer review auditor program with an independent inspection of audit firms. Upon completion of each inspection, the PCAOB issues inspection reports that include a public portion (Part I) of identified audit deficiencies, and most include a nonpublic portion (Part II) of identified quality control weaknesses which is not disclosed publicly unless the audit firm does not sufficiently complete remediation during the next 12 months. Upon issuance of the Part II report, I find that audit firms experience …

Engagement Levels During Implementation Of Co-Teaching Models, Cathy Lee Eschete Jan 2015

Engagement Levels During Implementation Of Co-Teaching Models, Cathy Lee Eschete

LSU Doctoral Dissertations

Student engagement in the classroom is a priority for educators and policy makers because disengaged students are more likely to perform poorly in school. Students with disabilities, particularly those with high-incidence disabilities, are a subset of that population of potentially disengaged and definitely poor-performing students. When attending school, they are served increasingly in inclusive, co-taught settings, allowing for inquiry into engagement practices in these instructional arrangements. One purpose of this study was document levels of student engagement for six commonly described co-teaching models implemented in a teacher education course for both special education and general education preservice teacher candidates and …

Selective Enrichment Through Capture (Sec): A Technology For Retrieving Specific Dna Sequences From Complex Mixtures, Kelley Gwin Nunez Jan 2015

Selective Enrichment Through Capture (Sec): A Technology For Retrieving Specific Dna Sequences From Complex Mixtures, Kelley Gwin Nunez

LSU Doctoral Dissertations

The capacity to selectively target DNA sequences within a complex mixture is a useful feature for genomic studies. Several methods aimed at undertaking this feat have utilized biotinylated oligonucleotides and streptavidin beads to capture DNA but have low efficiencies, require PCR, or cannot be combined with high-throughput sequencing. The work presented here developed a protocol referred to as selected enrichment through capture (SEC) that uses a biotinylated “capture primer” to target and concentrate specific DNA sequences at high efficiencies, eliminates the use of PCR, and can be combined with high-throughput sequencing. The effectiveness of SEC was evaluated in a series …
