Positional Effects Of Trna Genes: Transfer Rna Genes As Chromatin Boundaries In Saccharomyces Cerevisiae, Tiffany Anne Simms Jan 2006

Positional Effects Of Trna Genes: Transfer Rna Genes As Chromatin Boundaries In Saccharomyces Cerevisiae, Tiffany Anne Simms

LSU Master's Theses

Recently, much evidence has been brought forth into the scientific community supporting the idea that RNA Polymerase III transcribed regions of DNA may serve as chromosomal landmarks for silencing. Transfer RNA genes are known to involve themselves in several extra-transcriptional functions within the chromosome, including the pausing of replication forks, Ty element integration, tRNA position effects (repression of neighboring genes), acting as a barrier to the spread of heterochromatin, and over-riding nuclosome positioning sequences. Our results suggest that many tRNA genes may serve these functions as well as exhibiting behavior similar to metazoan insulators. Also, ETC (Extra TFIIIC) sites within …

Media Use, Hiv/Aids Knowledge, And Sexual Beliefs: An Exploration Of Differences Between Races, Tarana Hammond Jan 2006

Media Use, Hiv/Aids Knowledge, And Sexual Beliefs: An Exploration Of Differences Between Races, Tarana Hammond

LSU Master's Theses

As the numbers rise among African Americans who are contracting HIV/AIDS, it becomes evident that research is needed to examine where African Americans obtain HIV/AIDS information. This study identified where African Americans obtain HIV/AIDS information and examined how that information affects African Americans’ sexual beliefs about HIV/AIDS. The theoretical foundation for this study was the Health Belief Model (HBM). This study used a survey method. The data analysis demonstrated that race does influence the type of media an individual uses. Race does not impact an individual’s access to health information. Knowledge about HIV/AIDS impacts an individual’s sexual beliefs about HIV/AIDS. …

The Scent Of A New World Novel: Translating The Olfactory Language Of Faulkner And García Márquez, Terri Smith Ruckel Jan 2006

The Scent Of A New World Novel: Translating The Olfactory Language Of Faulkner And García Márquez, Terri Smith Ruckel

LSU Doctoral Dissertations

Both William Faulkner and Gabriel García Márquez introduce the olfactory as a focal element in their writing, producing works that challenge the singular primacy of sight as the unrivaled means by which the New World might be understood. As they translate experiences of the New World into language, both writers record the power of olfactory perception to reflect memory and history, to shape identity, to mark unmistakably certain crisis moments of ethical action, and to delineate a form of knowledge crucial to their New World poetics of the novel. Observing and analyzing the olfactory language particular to the cultural spaces …

Once Proud Princes: Planters And Plantation Culture In Louisiana's Northeast Delta, From The First World War Through The Great Depression, James Matthew Reonas Jan 2006

Once Proud Princes: Planters And Plantation Culture In Louisiana's Northeast Delta, From The First World War Through The Great Depression, James Matthew Reonas

LSU Doctoral Dissertations

The Delta country of northeast Louisiana is a richly productive alluvial region stretching south from the Arkansas line to the confluence of the Red and Mississippi Rivers below Natchez. As the source of great cotton fortunes made during antebellum times, it reflected the Old South ideal and, for several decades after the end of the Civil War, remained firmly grounded in this old plantation culture. The economic depression of the 1890s and the coming of the boll weevil in the early 1900s, however, signaled a gradual decline that turned into full-blown dissolution in the years following the First World War. …

The Effectiveness Of Virtual Facilitation In Supporting Gdss Appropriation And Structured Group Decision Making, Harold Joseph Lagroue Jan 2006

The Effectiveness Of Virtual Facilitation In Supporting Gdss Appropriation And Structured Group Decision Making, Harold Joseph Lagroue

LSU Doctoral Dissertations

Since their introduction a quarter of a century ago, group decision support systems (GDSS) have evolved from applications designed primarily to support decision making for groups in face-to-face settings, to their growing use for “web conferencing,” online collaboration, and distributed group decision-making. Indeed, it is only recently that such groupware applications for conducting face-to-face, as well as “virtual meetings” among dispersed workgroups have achieved mainstream status, as evidenced by Microsoft’s ubiquitous advertising campaign promoting its “Live Meeting” electronic meeting systems (EMS) software. As these applications become more widely adopted, issues relating to their effective utilization are becoming increasingly relevant. This …

Evaluating Preference For Reinforcers Under Varying Schedule Requirements In Children With Developmental Disabilities, Tiffany Michelle Kodak Jan 2006

Evaluating Preference For Reinforcers Under Varying Schedule Requirements In Children With Developmental Disabilities, Tiffany Michelle Kodak

LSU Doctoral Dissertations

Previous research has shown that preference for concurrently available reinforcers can be influenced by the reinforcement schedule (DeLeon, Neidert, Anders, & Rodriguez-Catter, 2001; Tustin, 1994). However, limited research has been conducted on specific variables that may influence preference under various schedule requirements. The present study evaluated the influence of task preference, schedule, and quality of reinforcement on choice between either an arbitrary reinforcer or a functional reinforcer. Five participants diagnosed with Autism participated in the study. In the first phase, we evaluated the effects of task preference and schedule of reinforcement on choice between a 30-s break and a high …

Validity Of The Reflux Symptoms Index For Post-Pubescent Female Vocalists, Natalie Herpin Overall Jan 2006

Validity Of The Reflux Symptoms Index For Post-Pubescent Female Vocalists, Natalie Herpin Overall

LSU Master's Theses

The Reflux Symptoms Index (RSI), a nine-item self-rated questionnaire, has been suggested as a way of monitoring severity of laryngopharyngeal reflux (LPR) symptoms during treatment. However, limited research has been conducted to assess the validity of the RSI as a way of identifying severity of laryngopharyngeal reflux (LPR) symptoms as differentiated from gastroesophageal reflux (GER) symptoms. Twenty-five post-pubescent female vocalists participated by completing a one-hour voice evaluation, including a Voice Handicap Index (VHI), an RSI, a Reflux Finding Score (RFS) completed with videostroboscopy for visualization of the laryngeal cavity, and analysis of an acoustic sample with the Multi-Dimensional Voice Profile …

Computer-Aided Diagnostic Systems For Digital Mammograms, Nicholas Jabari Lee Jan 2006

Computer-Aided Diagnostic Systems For Digital Mammograms, Nicholas Jabari Lee

LSU Master's Theses

A computer-aided diagnostic (CAD) system that uses a unique shape-based classification scheme, the Ellipse-Closed Curve Fitting (ECCF) algorithm, is developed for digital mammogram image analysis. The system is developed to work as a post-processing extension to a previously developed CAD system that locates and segments mass lesions, or tumors, found in digital mammograms into separate images. The ECCF system is implemented in the MATLAB mathematical scripting language and is thus capable of running on multiple platforms. The ECCF algorithm detects edges in tumor images and casts them into closed curve functions. Parameters for an ellipse of best fit for a …

"To Integrate Or To Differentiate?" - Towards Resolving A Multi-Channel Dilemma Investigation Of The Effects Of Channel Integration Strategies On Consumers' Evaluations Of Multi-Channel Utility And Their Adoption Of Multi-Channel Shopping, Elena Kiryanova Bernard Jan 2006

"To Integrate Or To Differentiate?" - Towards Resolving A Multi-Channel Dilemma Investigation Of The Effects Of Channel Integration Strategies On Consumers' Evaluations Of Multi-Channel Utility And Their Adoption Of Multi-Channel Shopping, Elena Kiryanova Bernard

LSU Doctoral Dissertations

Multi-channel retailers have been adopting different multi-channel formats that range from complete channel separation (e.g., Victoria's Secret) to close integration (e.g., Bed, Bath and Beyond). The purpose of this dissertation is to determine which multi-channel strategy offers the most value to multi-channel shoppers. The success of a multi-channel retailing strategy is believed to depend on the degree of channel complementarity as perceived by the retailer's customers. Channel complementarity is defined as the degree to which multiple retail channels work synergistically to create value. Complementary channels give customers integrated solutions that create more value than the sum of the parts. It …

Do Accruals Exacerbate Information Asymmetry In The Market?, Sonia Wasan Jan 2006

Do Accruals Exacerbate Information Asymmetry In The Market?, Sonia Wasan

LSU Doctoral Dissertations

A considerable body of evidence, both archival and experimental, suggests that accounting accruals are heterogeneously interpreted by investors. In this study, I examine whether the information asymmetry among investors arising from this heterogeneous interpretation, implied in these empirical results, affects transactions costs in the form of the bid-ask spread and its adverse selection component. I examine this impact both, in general, for all trading activity occurring for a firm over a continuous flow of information during the year and around the first release of accrual information for each quarter. The results of the study provide empirical evidence of a positive …

A Mixed Methods Study Of The Implications Of Academic Change Related Managerial Decisions On University Faculty Teaching Effectiveness And Student Success, Kelly Mulkey Mcfatter Jan 2006

A Mixed Methods Study Of The Implications Of Academic Change Related Managerial Decisions On University Faculty Teaching Effectiveness And Student Success, Kelly Mulkey Mcfatter

LSU Doctoral Dissertations

Determining why and what motivates students to succeed is a prominent question in today’s educational arena. Often accountability measures cycle around the classroom teacher, their preparation, and perceived effectiveness. To assure that teachers have adequate knowledge, minimum grade point averages are required from accredited institutions. Teacher preparation is carefully monitored by NCATE (National Council for Accreditation of Teacher Education). Each state uses a similar process for awarding initial teaching certificates. Teaching certificates are issued after candidates have completed a rigorous curriculum and proven that they possess the qualities and dispositions of effective teaching. Unfortunately, very few assessments exist to measure …

The Relationship Between Parent-Adolescent Conflict And Academic Achievement, Marie S. Nebel-Schwalm Jan 2006

The Relationship Between Parent-Adolescent Conflict And Academic Achievement, Marie S. Nebel-Schwalm

LSU Master's Theses

Previous research has shown family conflict to have a detrimental effect on the academic functioning of children and adolescents. Most research conceptualizes family conflict as marital distress or divorce. Additional factors that have been shown to effect academic functioning include cognitive ability (i.e., intelligence), academic skills (e.g., homework behaviors), and amount of resources (i.e., socioeconomic status, SES). The present study investigated whether parent-adolescent conflict is related to adolescent academic achievement after accounting for cognitive ability and homework behaviors. Participants include 74 middle school students attending public school in a low-SES urban environment. Prior to conducting analyses, parent and adolescent reports …

Writing As A Cultural Negotiation: A Study Of Mariama Bâ, Marie Ndiaye And Ama Ata Aidoo, Catherine Afua Kapi Jan 2006

Writing As A Cultural Negotiation: A Study Of Mariama Bâ, Marie Ndiaye And Ama Ata Aidoo, Catherine Afua Kapi

LSU Doctoral Dissertations

Critical review of the existing literature on African women writers clearly shows that nowhere is the question of writing as a cultural negotiation posed, discussed or much less addressed. This is a lacuna that this dissertation addresses for the first time by proposing a re-reading of the selected works of Ama Ata Aidoo, Mariama Bâ and Marie NDiaye through the new prism of writing as part of cultural negotiation. In doing so, the dissertation goes beyond the paradigm of binary oppositions that undergirds the critical literature on writing by Sub-Saharan women in favor of the innovative concept of negotiation.

A Multivariate Analysis Of Economic Reform In Latin America, 1980-1995, Ashley Dyan Ross Jan 2006

A Multivariate Analysis Of Economic Reform In Latin America, 1980-1995, Ashley Dyan Ross

LSU Master's Theses

The current literature on economic reform is fragmented and lacks a cohesive theoretical framework to fully explain the politics of neoliberal reform adoption. The multiple perspectives presented in the literature, including institutional, pluralist, macroeconomic, international pressures, and policy networks, create an incoherent explanation of economic liberalization. In an effort to more completely account for the political dynamics of the economic reform process, my analysis incorporates the primary variables supported by the literature on neoliberal reform within an informal institutions framework. My primary variable of interest is policy networks, and I support this with the theory of informal institutions while considering …

Communicating The Modern Entrepreneurial University In The 21st Century: A Case Study Of Academic Capitalism And Media Messaging In The Pursuit Of Revenues And National Prominence At Louisiana State University, Charles F. Zewe

LSU Doctoral Dissertations

American public universities have passed through three stages of development: the religious, the philanthropic/land-grant, and the federal research university. Squeezed by government budget cuts and demands for more money to pay for research and faculty raises, U.S. higher education has entered a fourth phase, the entrepreneurial university. Public universities are increasingly capitalizing on the intellectual property of their faculty and students to sustain themselves and expand. Administrators spout free-market rhetoric as faculty attempt to commercialize research by creating spin-off companies. Using Louisiana State University as a case study, this dissertation, applies a combination of organizational knowledge creation and resource dependence …

Stage(D) Mothers: Mother-Daughter Tropes In Twentieth-Century American Drama, Kristin Hanson Jan 2006

Stage(D) Mothers: Mother-Daughter Tropes In Twentieth-Century American Drama, Kristin Hanson

LSU Doctoral Dissertations

The relationship between mother and daughter is an important one for many women. In learning how to best become a successful member of society, daughters look to their mothers to demonstrate the behaviors and beliefs appropriate to a female. Such explicit and implicit instruction makes the mother-daughter relationship a central one in the socialization of women. Because it is such a powerful site, the mother-daughter relationship has received attention in the world of representation. Of particular import to this study is the representation of the mother-daughter relationship in Twentieth-Century American drama. Recent scholarship has shown that such representations can, however, …
