The Multiple Dimensions Of The Interfirm Network: The Critical Sources Of Product Innovation, Thongchai Srivardhana

LSU Doctoral Dissertations

This dissertation examines the impacts of interfirm variables on both invention and commercialization activities, following Greve’s (2003) suggestion that innovation research will be enriched if more studies integrate invention and commercialization activities to understand the entire innovation development process. Utilizing two established theoretical perspectives—organizational learning and institutional theory—six sets of hypotheses are developed containing the following interfirm variables: 1) direct and indirect ties, 2) strength of direct ties, 3) structural holes, 4) prominence of direct partners, 5) exploration and exploitation partners, and 6) horizontal and vertical networks. The dissertation also predicts that these interfirm variables would contribute to either invention …

A Comparison Of Dominance And Affiliation Ratings Based On Emotional State, Sex, And Status, Jennifer Bernardi

LSU Master's Theses

Perceptions of interpersonal dominance and affiliation have been extensively examined throughout past research. In the current study, the purpose was to fill in the some of the gaps of existing research well, specifically the gap created by current confusion in the literature regarding the effects of sex, status, and emotional display on ratings of dominance and affiliation. Also, interactions between the primary variables of interest (sex, status, and emotional display) were observed. Results revealed significant relationships within several of the dimensions addressed, specifically between emotional display and ratings of dominance and affiliation such that individuals displaying anger were viewed as …

Molecular Analysis Of Vibrio Vulnificus Phase Variants And Characterization Of A New Biofilm-Proficient Rugose Phenotype, Brenda L. Grau

LSU Doctoral Dissertations

Vibrio vulnificus is a marine bacterium capable of causing severe and fatal illness in susceptible people. The primary virulence factor is a capsular polysaccharide (CPS) that allows the bacteria to evade the host immune system. Two phenotypic forms were previously known to exist, opaque (virulent) and translucent (avirulent), and had been shown to undergo spontaneous phase variation, each switching to the other phenotype. Provided here is the first report of a third phenotype, rugose. The rugose variant is dry and wrinkled compared to the smooth colony morphology of the opaque and translucent forms. Both opaque and translucent strains produce rugose …

A New Method To Determine Radiative Properties Of Rough Solid Surfaces, Raghu Nandan Mutukulla

LSU Master's Theses

The radiative properties of the rough surfaces are important both from fundamental and practical standpoint. Thus, there is a need to determine the effect of roughness on radiative properties of materials accurately, as these properties effect the performance of electronic devices, communication devices, optical sensors, and furnaces, amongst others. The effects of roughness are assessed by measuring the reflection coefficients from the carbon rod surfaces and steel 1086 samples over the range of angles 25 to 75 in the visible range and near infrared region. Different levels of roughness are induced on the surfaces by utilizing different grid size sand-paper …

Media Framing Of Prescription Drug Coverage Following A Recall, Rebecca Ann Hotard

LSU Master's Theses

Direct-to-consumer advertising of prescription drugs receives significant attention from academic researchers. Advertising, however, is not the only way prescription drugs are discussed in the public sphere. Many Americans learn about science through mass media. Additionally, researchers believe readers place more trust in editorial content than in advertisements. This study took a quantitative and qualitative approach to content analysis of prescription drug coverage to examine the effects of the highly publicized and controversial Vioxx recall on the news. Significant changes in framing, drugs mentioned, and prominence of story placement were shown. There were no changes in sources used in prescription drug …

Investigation Of The Structure In Electrodeposited Nanostructured Co/Cu Alloys, Multilayers, And Cofe/Cu Multilayered Nanowires, Erick Jamal Lawson

LSU Master's Theses

Since the discovery of giant magnetoresistance (GMR) in electrodeposited nanostructured magnetic multilayers and multilayered nanowires, there has been interest throughout the scientific world in the fabrication and characterization of these materials. Magnetic multilayers in the form of thin films can be used as magnetoresistive sensors in the magnetic data storage industry. Arrays of nanowires have the potential for applications in perpendicular ultra-high density data storage and biosensors. Wire-shaped magnetic multilayered nanowires have been shown to exhibit GMR in the so called “current perpendicular-to plane” configuration (CPP-GMR). GMR of multilayers and multilayered nanowires have been investigated in several systems that include …

Characterization And Tribological Behavior Of Diamond-Like Carbon And Nitrogen-Doped Diamond-Like Carbon Thin Films, Krishna Chaitanya Kadiyala

LSU Master's Theses

Diamond-like carbon (DLC) films have been extensively studied for more than two decades due to their highly attractive properties. These films exhibit unique mechanical, electrical and tribological behavior and thus, possess great potential for applications in tribology. However, the high level of internal stress developed and low thermal stability are the main drawbacks. Synthesis of nitrogen-doped DLC (N-DLC) offers the possibility of overcoming these drawbacks. In the present study, DLC and N-DLC films (with low N content) were deposited on Si substrates using a hybrid plasma-assisted CVD/PVD process. Film characterization in terms of microstructure, composition and chemical state of components …

Target Audiences And Communication Channels Of Lighten Up Programs In The United States, Nancy Leah Borden

LSU Master's Theses

Several Lighten Up programs around the United States were qualitatively studied in efforts to determine their target audiences and the communication channels used to reach these audiences. To guide this study, principles from the social marketing framework and the diffusion of innovations theory were applied. Several Lighten Up program executive directors and other high-ranking individuals in charge of the programs were interviewed in-depth to answer questions pertaining to target audiences and communication channels. Inductive data analysis illustrated that programs did not segment their target audiences, that more programs depended on interpersonal and group communication than mass communication, and finally, that …

Phytoremediation Of A High Phosphorus Soil By Summer And Winter Hay Harvest, Veronica A. Ryan

LSU Master's Theses

Phosphorus (P) loading into surface water from runoff and subsurface flow leaving soils subjected to long-term applications of poultry litter (PL) will degrade water quality. A practical way to reduce such loading is to remove soil P through plant uptake and harvest removal. The primary field study presented here examined the effectiveness of hay harvest utilizing a double-cropped system - perennial warm-season forage grass, common bermudagrass (CB; Cynodon dactylon (L.) Pers.), overseeded with annual ryegrass (ARG; Lolium multiflorum Lam.), a cool-season forage, in reducing soil P from a Ruston fine-sandy loam impacted by PL amendments. A secondary field study similarly …

An Analysis Of The Relationship Between City Typology, Interactivity And Advertising Message Strategies Of American Municipal Web Sites, Jeremy John Starr

LSU Master's Theses

This study became to first to scientifically explore the relationship between city typology and the use of advertising message strategy and interactivity within municipal web sites. The study used Taylor’s six-segment strategy wheel to analyze message strategies and previous scales of interactivity to analyze structural interactivity. Medium-size cities and cities within the South and West geographic regions more likely used sensory strategies within their web sites. Cities with racially diverse populations more likely used sensory strategies within their web sites as well. Large cities and central cities, both with large populations, used the most interactive strategies within their sites compared …

“Peace Is More Than The End Of Bombing”: The Second Stage Of The Vieques Struggle, Sherrie Baver

Publications and Research

The nature of colonialism in Puerto Rico has caused most political issues to be viewed within the framework of status politics. In the first stage of the struggle to expel the U.S. Navy from the island (1999–2003), civil society in Puerto Rico united when the issues were reframed with links not to status politics but to human rights and social justice. Viequenses symbolized for Puerto Ricans in Puerto Rico, on the mainland, and in the world at large the costs of military colonialism. In the second stage of the struggle, since the military’s departure, Viequenses have struggled to control the …

Place, Sport And Globalization: Making Sense Of La Marca Barça, Hunter Shobe

Geography Faculty Publications and Presentations

The case of Football Club (FC) Barcelona provides a compelling case for
examining the impact of globalization on the place/identity role of football
clubs. FC Barcelona has deep historical connections to Barcelona and
Catalonia. These connections were de-emphasized by the clubs leadership
under Josep Lluís Núñez (1978-2000) and Joan Gaspart (2000-2003) and
promoted again by Joan Laporta and his directors (elected in 2003). At the
same time, under Laporta, FC Barcelona has developed into a successful
global brand. How are we to understand this renewed focus on the local and
national discourses of place while the team is simultaneously promoted …

Fact And Fiction: Writing The Difference Between Suicide And Death, John Carvalho

Contemporary Aesthetics (Journal Archive)

Did Michel Foucault die of AIDS or did he kill himself? Did he knowingly infect others in the bath houses in San Francisco or was he unaware that he was ill and of how less-than-safe sex could spread the same virus that infected him? What did he know about AIDS/HIV and what do we know about what he knew? Answers to these questions are ambiguous. This is due, in part, to the culture of homosexuality and the cultural response to AIDS/HIV at the time. It is also due to the conflicting reports about what Foucault knew, and when, in the …

Mathematical Model Of Arsenic Adsorption In A Modified Zeolite / Microfiltration System, Miles B. Beamguard

USF Tampa Graduate Theses and Dissertations

Carcinogenic health concerns over arsenic in drinking water caused the USEPA to reduce the maximum contaminant level (MCL) from 50 to 10 ppb, effective on January 23, 2006. This has forced many smaller utilities into expensive treatment or discontinuation of water distribution. Researchers throughout the world are working to develop an inexpensive method for arsenic removal to meet this MCL. Aluminum silicates, or zeolites, are naturally occurring ionic sorbents. Modification of a zeolite may enhance adsorption capacities and ion selectivity. This research investigates the arsenic adsorption capacities of a modified Chabazite. This adsorption, coupled with a hollow fiber, microfiltration membrane …

Arts In New Directions The Development And Application Of A Construct That Uses The Arts To Promote Transformation And Self-Actualization In Health Care And Education/Therapy, Alexxis Avalon

USF Tampa Graduate Theses and Dissertations

Artistic methods to evoke relaxation, spark creativity, and change self-perceptions are already being used by therapists, educators, and scientists. Interdisciplinary collaborations among researchers are developing to create new paradigms that incorporate the use of arts to empower individuals. By describing various connections between the arts and participants, researchers are looking at the expressive arts (including dance, music, drama, poetry, and visual arts) for transformation and self-actualization.The problem is that no construct is available to describe the transformation, "the conscious move from one deep structure of knowledge to another" (Wilber, 2004), that occurs when using the arts in health care and …

Adolescent Alcohol Use And Educational Outcomes, Wesley A. Austin

USF Tampa Graduate Theses and Dissertations

There is some controversy over whether adolescent alcohol use has deleterious causal effects on educational outcomes. In particular, does drinking reduce academic performance and school enrollment rates and increase truancy, or does the observed negative correlation between drinking and educational outcomes merely reflect common unobservable factors? This dissertation sheds further light on the issue by estimating the causal impacts of alcohol use on various educational outcomes. Specifically, an instrumental variables model is estimated to study the effects of several drinking measures on grades, school enrollment and absenteeism.
