Agenda Preference Deliberations, David Pulliam

LSU Master's Theses

Currently the public is relegated to the electoral process, surveys and polls, and group participation in order to voice their agenda preferences. Various literatures describe the decreasing influence of the general public within the agenda setting portion of the policymaking process. This thesis assesses the agenda setting and public policy literatures in order to determine how issues become part of the policy agenda, looks to the public opinion literature to determine how capable the public is in being part of the policymaking process, and utilizes the deliberative democracy literature to construct deliberations that make it possible to get the public …

The Rise Of The Surgical Age In The Treatment Of Pulmonary Tuberculosis: A Case Study Of The Mississippi State Sanatorium, Ashley Baggett

LSU Master's Theses

The historiography of tuberculosis, “TB,” covers four periods in the United States. During the Victorian Age, TB was classified as consumption. After Robert Koch’s discovery of the tubercle bacillus in the 1882, the germ theory took precedence. The early 1900s saw the rise of the Sanatorium Age, and finally, the antibiotic revolution of the 1940s and 1950s began the current understanding of the disease. Missing from this periodization is an era in which surgery took precedence as the preferred treatment for tuberculosis. This study corrects the historiography by arguing for a recognizable Surgical Age in the 1930s and 1940s. With …

Cooking Times And Temperatures For Safe Consumption Of Louisiana Blue Crabs (Callinectes Sapidus), Nicole Watson Hazard

LSU Master's Theses

While all seafood has the potential of being associated with foodborne illness, Louisiana blue crabs (Callinectes sapidus) are exposed to Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vulnificus, Listeria monocytogenes and Salmonella species in the estuarine habitat. This study was designed to determine the least amount of time and temperature needed to reduce or eliminate each of the aforementioned bacteria from a single Louisiana blue crab with either boiling or steaming heat treatments. Once the single crab heat treatment studies were completed, the bacteria that showed the greatest thermal resistance, Listeria monocytogenes, and the bacteria most associated with foodborne illness in Louisiana …

Framing Jewell: A Discourse Analysis Of Newspaper Coverage In The Aftermath Of The Atlanta Olympics Bombing And Discussion Of Legal And Ethical Standards For Such Practices, Anne L. Songy

LSU Master's Theses

This study examines the newspaper coverage of Richard Jewell during the weeks after the 1996 Atlanta Olympics bombing. Jewell, a security guard working in the Olympic Park on July 27, 1996, was initially hailed as a hero due to his discovery of a bomb minutes before the explosion. After Jewell’s name was leaked to the press as an FBI person of interest in the case, many reporters began to frame Jewell in a negative light and, in some instances, even implied his guilt. Through a discourse analysis of news stories published between the date of the bombing and the date …

Evaluating Different Health Communicatioin Theories To Deter College Binge Drinking: A Look At Promising Directions For Future Research, Kristen Meyer Sunde

LSU Master's Theses

ABSTRACT

For more than 30 years, college administrators and health communicators have used binge drinking prevention campaigns on university campuses to deter students from this dangerous and life-threatening habit.

Despite the prevalence of such campaigns (Wechsler, Seibring, Liu & Ahl, 2004), binge drinking remains the top public health threat for this population (Wechsler, Dowdall, Davenport, & Castillo, 1995).

In this study, the researcher conducted an experiment using fear appeals to see if these messages were more effective than social norms messages, which are often used in college binge drinking prevention campaigns (Real & Rimal, 2007), at prompting higher message credibility …

Desegregation And Multiculturalism In The Portland Public Schools, Ethan Johnson, Felicia Williams

Black Studies Faculty Publications and Presentations

Helen Marie Casey’s booklet Portland’s Compromise: the Colored School, 1867–1872 recounts the story of William Brown, an African-American resident of Portland, Oregon, and his role in the first and only case of official segregation of African-American children in Portland Public Schools (PPS) in 1867. After unsuccessfully trying to enroll his children in one of Portland’s only two public elementary schools, Brown appealed to the school board, including directors Josiah Failing, W.S. Ladd, and E.D. Shattuck. Again, his children were denied access. The board of directors explained their resistance to integrated schools by saying: “If we admit them [African-American children], then …

Audio Watermarking Using Transformation Techniques, Rajkiran Ravula

LSU Master's Theses

Watermarking is a technique, which is used in protecting digital information like images, videos and audio as it provides copyrights and ownership. Audio watermarking is more challenging than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. This thesis attempts to solve the quantization based audio watermarking technique based on both the Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). The underlying system involves the statistical characteristics of the signal. This study considers different wavelet filters and quantization techniques. A comparison is performed on diverge algorithms and audio signals to help examine the performance …

Burkholderia glumae is the bacterial pathogen causing bacterial panicle blight disease of rice (BPB). The pathogen, whose growth and pathogenicity is favored by high temperatures, has become a serious threat to rice production around the world possibly due to the current global climate changes. In this study, previously reported avirulent B. glumae strains were characterized in respect to the production of known virulence factors, toxoflavin, lipase and motility, and potential virulence factors, including polygalacturnase and type III secretion system (hypersensitive response). Considerable phenotypic variation was observed among the strains tested. Virulence of the B. glumae strains was closely related to …

Communication Deficits In Babies With Autism And Pervasive Developmental Disorder - Not Otherwise Specified (Pdd-Nos), Max Horovitz

LSU Master's Theses

Autism Spectrum Disorders (ASDs) are characterized by pervasive impairments in communication, socialization, and repetitive behaviors or interests. While there is a growing interest in early ASDs, very few studies have looked at the nature of these impairments before age 3. In order to better strengthen early assessment and intervention for ASDs, more knowledge is needed in this area. The current studies aimed to determine if, and in what ways, communication impairments are present in infants and toddlers (17-37 months) diagnosed with autism and Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS). In the first study, infants with autism and PDD-NOS …

Public Perception Of Wildfire Risk And Prescribed Burning In The Wildland/Urban Interface Of The Louisiana Florida Parishes, Charlotte Ann Gerald

LSU Master's Theses

Wildfire has been suppressed in the nation’s forests for over a hundred years. The accumulation of forest fuels over time has created an urgent need to reduce fuel loads to prevent catastrophic wildfires from occurring, not only in our wildlands, but also in our Wildland/Urban Interfaces (WUI’s). The residents who live within the WUI are particularly vulnerable to extreme wildfire events. As cities become more densely populated, increasing numbers of people are moving beyond the suburbs into the WUI. A complex matrix of structures and forested land, developing communities, and impinging forests exists within the WUI. This study utilized a …

It's The Principal Of The Thing: Guiding A Rural School Has Its Own Trials, Susan Wilson, Tim France

Metroscape

The difficulties of K-12 education have become familiar to citizens of the metroscape, but they are usually viewed through the lens of urban and suburban schools, with their problems of multi-ethnic populations, crowded classrooms, strained budgets, and the like. Metroscape® was curious about the struggles and triumphs of the schools in the rural areas of the region, so we sent our interviewer, Susan Wilson, a Portland freelance writer, to Willamina to talk to a small town education leader in hopes of glimpsing the realities of schooling kids in that often overlooked setting.

A small-town principal is a versatile member of …

The Role Of Old-Fashioned Racism: Disaggregating Symbolic Racism In The United States, Leslie Curtis Cox

LSU Master's Theses

Old-fashioned, biological, or "Jim Crow" racism is viewed by many in the political science and psychology literature to be largely a relic of the past. In the post-segregation era it has been replaced as a political force by symbolic racism, although its residual effect still operates within symbolic racism as negative racial affect. Symbolic racism is thought of as a coherent belief system that describes whites‘ attitudes not only in the United States, but in some European democracies as well. This conceptualization of symbolic racism ignores the differences in the historical legacy of racism across different regional and demographic contexts. …

Solid-Liquid Separation Technologies In The Conversion Of Bagasse To Liquid Fuel, Keith Miller

LSU Master's Theses

Development of liquid biofuels has entered a new phase of large scale pilot demonstrations. A number of plants in operation or under construction face the engineering challenges of creating a viable plant design, scaling up, and optimizing various unit operations. It is well-known that separation technologies account for 50-70% of both capital and operating costs. Processes vary in terms of selection of unit operations; however, solid-liquid separations are likely to be a major contributor to the overall project costs. A typical process for ethanol production from biomass includes several solid-liquid separation steps. The nature of biomass derived materials makes it …

The Blame Is In The Frame: Inter-Reality Comparisons Of Crime Reports And Local News Crime Coverage On The Internet, Dana Marie Tumblin

LSU Master's Theses

Research of crime news suggests that Blacks are over represented as criminals when compared to crime reports; study of race and crime judgments reveals that viewers with heavy amounts of television news viewing associate Blacks with crime more often than viewers who watch lower amounts of television news. Further complicating the perception of Blacks is their lack of diversified coverage in the news. Most coverage of Blacks frames them as liabilities to their communities, while offering few positive depictions to counter the Black criminality frame. The Internet may aid in exacerbating stereotypes of Blacks by allowing users to selectively expose …

Caged Morpholino Oligonucleotide For Control Of Gene Expression In Zebrafish, Chad Michael Jarreau

LSU Master's Theses

To control gene expression in vivo with spatial and temporal precision remains a significant hurdle in laboratory studies of development as well as clinical genetic therapies. Here we demonstrate such control over gene expression by use of photochemistry to reversibly inactivate the hybridization of a nucleic acid analog used for specific protein knockdown. A morpholino oligonucleotide, commonly used for knockdown of protein expression in developmental studies, was “caged” using carbodiimide conjugate chemistry which yielded photocleavable adducts that can be removed with light exposure. Photochemical inactivation approaches to produce caged molecules have been used to control the spatiotemporal activity of biomolecules …

Communicating Conservation: Public Relations Practitioners' Communication Efforts To Inform The Public Of The Detriments Of Coastal Erosion And Wetlands Loss, Stephanie Ellene Shaddock

LSU Master's Theses

Coastal erosion is a serious problem that directly affects Louisiana and indirectly affects the entire United States. Between 1990 and 2000, Louisiana lost 24 square miles of land per year, which equals an approximate football field lost every 38 minutes (Barras, Bourgeois, & Handley, 1994). Hurricanes Katrina and Rita in 2005 accelerated this land loss by transforming 217 square miles of marsh into open water (United States Geological Survey, 2006). As a leader in seafood, oil, and gas production, and shipping state, Louisiana and the nation have much at stake with continued land loss. To inform Louisiana’s citizens and a …

"Unspottyd Lambs Of The Lord": Presbyterianism And The People In Elizabethan London, Katherine E. Sawyer

LSU Master's Theses

The official English church in the mid-sixteenth century vacillated back and forth between Catholicism and Protestantism, the two rivals of European Christianity. As these changes engendered a broad array of disagreements over issues such as liturgical practices, clerical attire, and church ornamentation, this thesis focuses on the most provocative of these debates-presbyterianism-and its proliferation among the men and women of Elizabethan London. Despite the propagation of presbyterian-style nonconformity in several regions of Elizabeth's realm, London functioned as the epicenter of this challenge to religious orthodoxy. From their location at the economic, religious, and cultural heart of the nation, Elizabethan Londoners …

The Role Of Race In Television News Coverage Of Shortcomings In U.S. Secondary Education, Jasmine Elise Haynes

LSU Master's Theses

Scholars and news media alike acknowledge that one of the main problems in education today is the minority achievement gaps in national testing. Although many education scholars have compiled several in-depth reasons as to why minorities, particularly African-American students, seem to generally lag behind their white counterparts, television news fails to give it’s audiences a comprehensive view of why minority achievement gaps are so prevalent in United States secondary public education. The purpose of this study was to examine where news consumers perceive television news places blame for problems in public education with regards to race. Studying how people perceive …

14-3-3 Sigma Interacts With Liver X Receptor Beta, Emily Ann Jackson

LSU Master's Theses

Atherosclerosis is the leading cause of mortality in developed countries accounting for 50% of all deaths. Atherosclerosis develops when macrophages in the artery wall accumulate large amounts of cholesterol via uptake of oxidized low density lipoproteins (LDL), causing a negative effect on cholesterol metabolism. Thus, the development of atherosclerosis can be inhibited by increasing cholesterol efflux, which can be achieved by activating ATP binding cassette (ABC) transporters in macrophages. In particular, ABCA1 mediates reverse cholesterol transport to the liver via high density lipoproteins (HDL) and therefore is an attractive molecular target for raising HDL levels and protecting against atherosclerosis. ABCA1 …

"Everybody Goes Down": Metaphors, Stories, And Simulations In Conversations, L. David Ritchie

Communication Faculty Publications and Presentations

Recent work has shown that many problematic aspects of metaphor use and comprehension can be resolved through an account that includes both relevance and perceptual simulation. It has also been shown that metaphors often imply stories, and that stories are often metaphorical. Previous research on narratives has focused primarily on stories that appear either in formal literature or in structured interviews; this essay focuses on stories that occur as an integral part of conversation. It extends recent work on metaphor comprehension to show how use and comprehension of stories in natural, informal conversations can be usefully analyzed in terms of …

Democratic Triumph, Scholarly Pessimism, Bruce Gilley

Political Science Faculty Publications and Presentations

This article discusses how the democratic form of government has gone from an oddity to the most common form of government in the world. The written works on democracy in the past twenty years have dealt primarily with the writers' growing sense of insecurity, the belief that history runs in cycles, and the belief that democracy will run its course and the world will find itself returned to an authoritarian existence. Samuel P. Huntington expressed his pessimism with democracy in his book "The Third Wave." Huntington believes that only countries with a substantial Western influence will be able to sustain …
