Media Ownership And Objectivity, Xinkun Wang

LSU Master's Theses

The purpose of this study is to examine whether the different type of ownership will affect the degree of objectivity of newspaper coverage of 2000 presidential election. It is predicted by Shoemaker’s news content theory that publicly-owned newspaper is more objective than privately-owned newspaper. The findings of this study support this theory. A content analysis of 238 news stories and eight editorials from publicly-owned the Boston Globe and privately-owned the Boston Herald showed that not only does the ownership affect the objectivity of the coverage of these two newspapers on 2000 presidential election, the endorsements also affect the degree of …

Generalized D-Sequences And Their Applications To Cdma Systems, Radhika Vaddiraja

LSU Master's Theses

Code Division Multiple Access (CDMA), a form of spread spectrum communications is used widely in cellular telephony. CDMA systems employ Walsh-Hadamard orthogonal codes, jointly with Pseudo-Noise (PN) sequences, Gold sequences and Kasami sequences to achieve spreading. This thesis investigates properties of generalized d-sequences and their applications as spreading sequences in CDMA systems. The correlation properties of these sequences are studied. The autocorrelation function of these sequences is not exactly two-valued but the cross correlation values are zero for certain class of these sequences. The zero cross correlation property can be useful in solving the near-far problem in CDMA communication systems, …

The study focused on four research issues: 1) child care directors’ definitions of continuity of care, 2) directors’ implementations of continuity of care, 3) if the directors’ practices violate their definitions what is the directors’ perceptions of the reason(s), and 4) if the directors’ practices violate their definition what is the reasons for the violations as perceived by an outside observer. The sample consisted of 4 child care directors who direct highquality, …

Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar

LSU Master's Theses

Numerical calculations of the aqueous humor dynamics in the anterior chamber of both the rabbit and the human eye are presented to delineate the basic flow and transport mechanisms. The calculations are based on a geometrical model of the eye, which represents the Trabecular mesh (TM) as a multi-layered porous zone of specified pore sizes and void fraction. Buoyancy is observed to be the dominant driving mechanism for the convective motion in both orientations (horizontal and vertical) of the eye. Reducing the TM pore size does not appear to have a significant influence on the intra-ocular pressure (IOP) until the …

Heavy Smokers Choose Large, Immediate Rewards With Large Penalties On A Simulated Task Of Gambling, Michael Shawn Businelle

LSU Master's Theses

The Gambling Task is a complex neuropsychological test (in the form of a card game) that examines the ability of individuals to assess potential immediate gains over long-term losses. Gambling Task performance has been examined in previous studies with individuals who are dependent on alcohol, cocaine, heroin, and amphetamine. These studies have shown that those who are dependent on the aforementioned substances perform more poorly on the Gambling Task than controls. Specifically, in relation to controls, drug/alcohol dependent individuals show impairment by tending to pick more cards that have large immediate gains and very large delayed punishers. The delayed punisher …

Development Of A Performance-Based Design Approach And Related Loads For Facilities Designated As Essential During A Hurricane Event, Joffrey Elliott Easley

LSU Master's Theses

Historically, shelters and other facilities designated as "essential" during hurricanes have experienced unacceptable damage during recent hurricanes, exposing the occupants to uncomfortable and dangerous conditions. One of the reasons for this is the lack of standards or design guidelines addressing the special considerations required for such facilities. A new approach to the design of essential facilities in hurricane regions is proposed. The goal of this work is to create a tool for improving the safety and serviceability of evacuation shelters and other critical facilities utilized during hurricane events. This is achieved by developing a new philosophy based on selection of …

Evaluation Of Static Low Density Media Filters For Use In Domestic Wastewater Treatment, Cynthia Wagener

LSU Master's Theses

Static Low Density Media (SLDM) filters are submerged granular medium filters that contain a static matrix of floating media. These filters provide concurrent biological and physical treatment, and are therefore classified as bioclarifiers. Through different design and operation strategies, SLDM filters may be used for a variety of functions such as: solid-liquid separation alone, organic conversion and solids capture, nitrification and solids capture, and denitrification and solids capture. For operation as an aerobic unit, an external aeration strategy was developed to preserve the static nature of the bed. In this study, SLDM filters treated a highly variable flow domestic wastewater …

The Effect Of High Frequency Amplification On Subjective And Objective Benefit With Digital Hearing Instruments, Erica Lynn Fleck

LSU Master's Theses

The purpose of the present study was to determine whether amplifying beyond 3 kHz was beneficial to the user, whether the benefit was dependent on degree of loss, and whether subjective data reflected the benefit. Seventeen hearing impaired subjects were binaurally fitted with digital hearing instruments. Qualified subjects were divided into two groups, A and B. Group A had a pure tone average (3,4, and 6 kHz), of 55 dBHL or better. Group B had a pure tone average (3,4, and 6 kHz) greater than 55 dBHL but not exceeding 75 dBHL.

Dialogic Dogs And Phatic Felines: Speaking To And Through Our Pets, Nicole M. Dufour

LSU Master's Theses

While many pet owners acknowledge that they speak to their pet, Pet Communication has remained mostly overlooked by researchers. Through discourse analysis, this thesis is an attempt to analyze Pet Communication, which deals with human speech to a pet, about a pet, or through a pet. I analyze data which I transcribed in the waiting room of the Louisiana State University School of Veterinary Medicine Small Animal Clinic. Data were collected from conversations that took place between pet owners, between pet owners and the Clinic's staff, pet owners and their pets, and between staff and pets. These data were then …

Sensory Characteristics Of Flavored Milk Candies, Noemi Raquel Pavon

LSU Master's Theses

A natural milk candy, composed mainly of milk powder, has not been commercially sold in the U. S. market. The milk candy we developed contains calcium and other essential nutrients, which make it a potential food supplement for adults and children. This thesis research was designed to characterize sensory properties of flavored milk candies and to determine the consumer sensory profile driving product acceptance and purchase intent. A descriptive trained panel (n=12) developed a lexicon and evaluated 3 milk candies (plain, chocolate, and coffee) in triplicate using a 15-cm line scale. 335 adult consumers evaluated acceptability of appearance, size/shape, texture, …

Evaluation Of Repeated Removal Of Mammalian Predators On Waterfowl Nest Success And Density, Kristen Dawn Chodachek

LSU Master's Theses

Low levels of nest success in the prairie pothole region are mainly attributed to changes in predator community and abundance. Removal of predators from large sites (≥ 4144 ha) has been an effective strategy for increasing nest success; however, trapping small sites (< 301 ha) is considered ineffective. I examined the effects of removing predators from 10, 259 ha sites in northeastern North Dakota during 2001-2002. Overall nest success for both years was greater on trapped sites (53.4%) than non-trapped sites (28.7%). Furthermore, daily survival rate was greater on removal sites, and was positively correlated with total predators removed. Differences in nest density were apparent between treatments with an increased nest density on trapped sites, however year had no effect. Pair densities did not differ between treatments, but a 2-fold increase for both trapped and non-trapped sites was found in spring 2002. Cost to produce one fledged duckling, combining all species ranged from $16-20. Overall, the results of this study indicate that repeated removal of predators on small sites is an effective strategy for increasing waterfowl production; however, feasibility will ultimately depend on the user group, budget limitations, landowner objectives, and public acceptance.

How Should Sports Organizations Handle A Crisis?: A Focus On Collegiate Institutions, Jamie Mabile Delatte

LSU Master's Theses

The sports industry is big business just like any other big business. Sports organizations face various crises just as corporate America does. A survey of 345 professional and college level sports organizations revealed that 70% of them experienced a crisis in 1997, while the Los Angeles Times reported that 220 college athletes were the focus of criminal charges in 1995. "Sports crises are clearly more frequent today than ever before," said Kathleen Hessert. Mike Paul agrees with that trend based on his research, attributing the trend to poor life choices away from the sport. What is a crisis? A crisis …

Do Terraces And Coconut Mats Affect Seeds And Submerged Aquatic Vegetation At Sabine National Wildlife Refuge?, Aaron Bailey Caldwell

LSU Master's Theses

Terraces are a widely used wetland restoration tools in coastal Louisiana, yet the benefits of terraces are poorly documented. Like terraces, coconut mats also may increase abundance of submerged aquatic vegetation (SAV), but their benefits are undocumented. I compared SAV and seed abundance in a marsh pond among three treatments: terrace, coconut mat, and marsh.

I evaluated terraces constructed in 1999 and coconut mats installed in 2001 in portions of unit 7 of Sabine National Wildlife Refuge that converted from emergent marsh to open water between 1956 and 1978. I randomly selected 3 terrace, marsh, and coconut mat stations. I …

An Ecopath/Ecosim Analysis Of An Estuarine Food Web: Seasonal Energy Flow And Response To River-Flow Related Perturbations, Laura Lynette Althauser

LSU Master's Theses

Estuaries are often the receiving basins for major river systems which makes them vulnerable to anthropogenic influences. I used Ecopath and Ecosim to investigate the structure of the Weeks Bay, Alabama, USA food web, and the responses of the food web to bottom-up perturbations. Four season-specific steady-state Ecopath models were developed and used to compare the production, biomass, consumption, biomass flows, and higher order indices of ecosystem functioning of the Weeks Bay food web under winter, spring, summer, and fall conditions. The season-specific Ecopath snapshots indicated that the structure of the Weeks Bay food web was resilient. Winter had the …

Five Films Of Steven Soderbergh, Donald Beale

LSU Master's Theses

This study examines five films of Steven Soderbergh: sex, lies, and videotape (1989), The Underneath (1995), Out of Sight (1998), The Limey (1999), and Traffic (2000). For each film, themes and cinematic form and technique are analyzed with the intent of demonstrating a consistent authorial voice of the director. The investigation reveals that common themes include the protagonist at odds with the world about him, journey, ambiguities and uncertainties in the characters' worlds, and the nondichotomous nature of reality, especially in regard to morality. The study also argues that Soderbergh has evolved a style that favors a nonlinear narrative and …

Adaptive Image Filtering Using Run-Time Reconfiguration, Nitin Srivastava

LSU Master's Theses

This thesis implements an adaptive linear smoothing image filtering algorithm, on a Virtex™-E FPGA using run-time reconfiguration (RTR). An adaptive filter uses a filtering window that runs over the entire image pixel-by-pixel, generating new (filtered) values of the pixels. As the name suggests, an adaptive filter can adapt to the varying nature of an image by adjusting the coefficients of the filtering window depending upon the local variance in the intensity values of pixels. It filters an image in a non-uniform fashion providing greater smoothing in largely uniform areas of the image and lesser smoothing when it encounters edges and …

Nekton Utilization Of Restored Habitat In A Louisiana Marsh, Christina Samantha Bush

LSU Master's Theses

Marsh terracing and coconut fiber mats are two restoration techniques currently being implemented at Sabine National Wildlife Refuge. We tested two hypotheses related to these restoration techniques: (1) marsh terracing enhances nekton assemblages, so that nekton use is similar to those at natural marsh edges, and (2) coconut matted marsh edges enhance SAV recruitment, so that nekton use is similar to those found at natural marsh edges. Samples from terraces and coconut matted marsh were compared to samples from the natural marsh and open water habitats. We measured the following variables at each habitat: (1) nekton density and abundance, (2) …

Relative Efficacy Of School-Home Notes With And Without Response Cost In Impoverished Elementary School Students With Attention-Deficit/Hyperactivity Disorder, Andrea Nichole Jurbergs

LSU Master's Theses

Daily report cards and punishment have proven to be effective methods of classroom behavior management. However, treatment effectiveness studies have not been designed to adequately compare the effects of rewarding and punishing consequences on behavior through a school-home note. The study of school-home note treatment effectiveness has focused on middle-class students with behavior problems; both ADHD and disadvantaged populations have been underresearched. Using a reversal, alternating treatments design, the present study will examine the effectiveness of a response-cost system added to school-home notes for increasing classwork completion and appropriate classroom behavior in several disadvantaged elementary school children with ADHD.

Behind The Scenes: Uncovering The Structures And Manipulations Of Tabloid Talk Show Workers, Guests And Audiences, Kelly Thompson Losch Deshotel

LSU Master's Theses

How talk show workers, guests and audiences behave behind-the-scenes is largely a mystery to the public. This research focuses on the behind-the-scenes workings of a daytime syndicated talk show to better understand the motivations of talk show guests and how talk show workers manipulate guests and audiences. While researchers have conducted studies of talk show guests using formal interviews and questionnaires, no researchers have posed as covert observers to study talk shows. The researcher conducted participant observation to study the behaviors of those involved with the on and offstage talk show structure. The researcher interned for the show without revealing …

Re-Evaluating The Mausoleum Of Galla Placidia, Lisa Onontiyoh West

LSU Master's Theses

The Mausoleum of Galla Placidia has generated a lengthy bibliography over the centuries but, in spite of repeated investigations, the north and south arm barrel vaults have received almost no attention. Commentary on these areas of the mosaic program is usually brief and limited to a comparison between the appearance of the barrel vaults and patterns found in various textiles, such as carpets. This thesis seeks to fill the void in the body of scholarly research pertaining to the north and south arm barrel vaults by viewing their decorative motifs through the eyes of a fifth-century Christian. When seen from …

Scalable Parallel Molecular Dynamics Algorithms For Organic Systems, Satyavani Vemparala

LSU Master's Theses

A scalable parallel algorithm, Macro-Molecular Dynamics (MMD), has been developed for large-scale molecular dynamics simulations of organic macromolecules, based on space-time multi-resolution techniques and dynamic management of distributed lists. The algorithm also includes the calculation of long range forces using Fast Multipole Method (FMM). FMM is based on the octree data structure, in which each parent cell is divided into 8 child cells and this division continues until the cell size is equal to the non-bonded interaction cutoff length. Due to constant number of operations performed at each stage of the octree, the FMM algorithm scales as O(N). Design and …
