The Influence Of An Active Postvention On The Length Of Time Elapsed Before Survivors Of Suicide Seek Treatment., Frank Ray Campbell

LSU Historical Dissertations and Theses

Those who are significantly impacted by the death of someone to suicide are known as survivors of suicide. This study examined two groups of suicide survivors, one group received an active postvention model (APM), and the other group received no active postvention model. The study utilized both t-test and chi-square to compare the groups based on key demographic characteristics. The study compared model of postvention (active versus passive) for the time elapsed between the suicide and the survivors seeking treatment. The two groups studied were survivors who sought treatment at a well established metropolitan crisis intervention center in the southern …

Navigating Knowing/Complicating Truth: African American Learners Experiencing Oral History As Real Education., Lavada Taylor Brandon Jan 2001

Navigating Knowing/Complicating Truth: African American Learners Experiencing Oral History As Real Education., Lavada Taylor Brandon

LSU Historical Dissertations and Theses

Dominant explanations for why urban African American learners dropout is that these students are "at-risk" (Swanson, 1991; Sartain,1989; Levine, 1988; Macchiarola, 1988). Such explanations blame the victim while exonerating the role schooling plays in shaping students' "at-risk" conditions (Woodson, 1933/1998; Tatum, 1997; Freire, 1970/1997; Shujaa, 1994; Gordon, 1993). This research contests these explanations for why African American learners dropout by centering 10 African American students' voices to highlight the role curriculum plays at casting them at-risk. Consequently, this work shifts reproach from individual students' home environments to the larger structural dimensions of curricula (what we know) and instruction (how we …

An Economic Analysis Of The Allocation Of Research Funding At The National Institutes Of Health., Janet B. Daniel Jan 2001

An Economic Analysis Of The Allocation Of Research Funding At The National Institutes Of Health., Janet B. Daniel

LSU Historical Dissertations and Theses

Our model examines the allocation of medical research funds at the National Institutes of Health using public interest theory, incremental budgeting theory, and special interest group theory. We use the allocation of research funds among various diseases and measures of the burden of disease on the population to test the hypothesis that the N.I.H. is allocating funds on a pure public interest basis, to test for incremental budgeting effects, and to test for the influence of lobbying and other political variables representing special interest groups. We use pooled cross-sectional, time-series data in a one-way fixed effects model, and also use …

Physiology And Lateralization Of Swallowing: A Comparison Between Young And Old Adults., Stephanie Kay Daniels Jan 2001

Physiology And Lateralization Of Swallowing: A Comparison Between Young And Old Adults., Stephanie Kay Daniels

LSU Historical Dissertations and Theses

Age-related changes in discrete swallows have been well researched, but few studies have investigated sequential swallowing with little emphasis on age-related changes. It is also unclear whether the cortical representation of swallowing is lateralized to one hemisphere or is bilaterally represented. As such, the aims of this research were to examine deglutitive biomechanics of sequential straw swallowing (Experiment I), and study swallowing lateralization using a dual task paradigm in healthy, young and old adults (Experiment II). Thirty-eight right-handed men (young = 20, old = 18) were studied. Experiment I: Videofluoroscopic swallow samples of two 10-second straw drinking trials were obtained. …

T -Cell Cytokines And Equine Nematode Infections., Jenifer Dee Edmonds

LSU Historical Dissertations and Theses

To address the role of parasites on subsequent antigenic challenge, humoral, lymphoproliferative and cytokine responses to a single intramuscular injection of keyhole limpet haemocyanin (KLH) were compared between groups of ponies with high, medium or low gastrointestinal parasite burdens. Heavy and moderately parasitised animals showed a trend towards reduced KLH-specific lymphoproliferation and reduced antigen specific total immunoglobulin, IgG(T) and IgA compared to lightly parasitised ponies. The peripheral blood mononuclear cells (PBMC) from medium and heavily parasitised ponies also had significantly lower levels of IL-4. These data indicate that heavily parasitised animals have uniformly decreased cellular and humoral immune responses to …

Performativity And Performance: Representing The Tattooed Body., Mindy Elaine Fenske Jan 2001

Performativity And Performance: Representing The Tattooed Body., Mindy Elaine Fenske

LSU Historical Dissertations and Theses

In this study I examine visual representations of tattooed bodies in three arenas of cultural production: tattoo conventions, advertising, and neo-tribal books. Through the methodological lens of genealogies of performance, I analyze these texts' construction of the tattooed body as classed, gendered, and exotic. I argue that contemporary representations of the tattooed body resist and reproduce discursive power regimes by surrogating prior cultural performances and representations of performance. I argue that contemporary visual representations of the tattooed body succeed in resisting discursive authority when they performatively cite multiple and transgressive authorities. I additionally indicate that the body in representation transgresses …

Body Condition, Leptin, And Reproductive Characteristics In Horses., Laura Roland Gentry Jan 2001

Body Condition, Leptin, And Reproductive Characteristics In Horses., Laura Roland Gentry

LSU Historical Dissertations and Theses

A series of experiments was conducted to gain a better understanding of the effects of nutrition and hormonal manipulation on the reproductive processes of the horse. In Experiment 1, body condition score (BCS) and ultrasonic backfat measurements were highly correlated in mares, especially over the tailhead area. In Experiment 2, high BCS (HBCS) mares continued to ovulate during the winter anestrous period, whereas low BCS (LBCS) mares went deeply anestrous. Daily hormone concentrations were not affected by BCS, however, responses to hormonal challenges indicated cyclicity in HBCS mares and reproductive quiescence in LBCS mares. In Experiment 3, treatment of average …

Statistical And Simulation Modeling Of Brown Shrimp Population Dynamics In The Northern Gulf Of Mexico., Heather Lynn Haas Jan 2001

Statistical And Simulation Modeling Of Brown Shrimp Population Dynamics In The Northern Gulf Of Mexico., Heather Lynn Haas

LSU Historical Dissertations and Theses

This dissertation used statistical and simulation modeling to examine population dynamics of brown shrimp, Penaeus (Farfantepenaeus ) aztecus. Brown shrimp are ideal to use in examining recruitment because shrimp represent a common life history strategy, because they are commercially important, and because there are extensive data available. In the first section of this dissertation, I used long-term monitoring data to examine correlative relationships between annual, stage-specific abundance estimates and environmental factors. Criticisms of traditional correlative studies were addressed by using a spatially and temporally-extensive dataset, by comparing stepwise multiple regression to Bayesian model averaging, and by investigating nonlinear relationships with …

Factors Associated With Research Anxiety Of Human Resource Education Faculty In Higher Education., Chadwick Charles Higgins Jan 2001

Factors Associated With Research Anxiety Of Human Resource Education Faculty In Higher Education., Chadwick Charles Higgins

LSU Historical Dissertations and Theses

The dissertation examined factors associated with research anxiety of university faculty members. Faculty at research universities have, in the past and at the present, had to deal with pressures associated with roles as researchers, teachers, and service initiators (Miller, 1994). The "publish or perish" atmosphere that accompanies most research university faculty positions often generates questions regarding confidence in one's ability to not only conduct meaningful research, but also to develop a solid and statistically sound research study. The purpose of the study was to determine if certain factors explain possible causes of research anxiety in higher education. These factors included …

Treatment Outcome Of Childhood Obesity: The Effect Of Children's Psychological Distress And Problematic Behavior., Tana Louise Hope Jan 2001

Treatment Outcome Of Childhood Obesity: The Effect Of Children's Psychological Distress And Problematic Behavior., Tana Louise Hope

LSU Historical Dissertations and Theses

The number of children and adolescents effected by obesity has been increasing over the past 30 years. Current treatment of childhood obesity focuses primarily on increasing physical activity, modifying diet, providing nutritional education and teaching self-monitoring and stimulus control procedures. Although children have been shown to lose weight by participating in these treatment programs, the amount of weight children lose during treatment is often small, and long-term maintenance of weightloss continues to be challenging for many. Given the relatively weak outcome of childhood obesity treatment programs, research into factors that effect treatment outcome is needed. Psychological distress and problematic behavior …

Examination Of A Method For Increasing Adjustment To And Compliance With Nasal Continuous Positive Airway Pressure (Cpap) In Persons With Obstructive Sleep Apnea Syndrome., Jack Allen Johnson Jr

LSU Historical Dissertations and Theses

Obstructive sleep apnea syndrome (OSAS) is a serious medical condition that occurs during sleep and consists of episodes of complete (respiratory pauses) or partial obstruction (hypoventilation) of the upper airway. Approximately 80% of persons diagnosed with OSAS are prescribed nasal Continuous Positive Airway Pressure (CPAP) treatment, which has proven to be the treatment of choice for OSAS. However, noncompliance with CPAP treatment in OSAS patients is a widely recognized problem, and many persons refuse CPAP as a treatment option or fail to use it reliably. Investigations of CPAP use in OSAS patients have generally found that nightly use averages less …

English Immersion Program In Korea: Student Progress After Four Months Of Implementation., Jaiwon Jung

LSU Historical Dissertations and Theses

In Korea, efforts to teach a non-native language, such as English, to Korean students usually result in native speakers acquiring limited language abilities. As a result, the teaching of English has little effect upon making native speakers fluent in a non-native language. Many foreign language instructors in Korea attempt to find new teaching methods to improve the performance of students in foreign language proficiency. Among the various innovative approaches of the 20th century, research has shown that the immersion approach may be one of the most effective means. Thus this dissertation introduces the innovative immersion teaching methods for Korean school …

Parenting Practices As A Moderator Of Exposure To Community Violence., Nicole Francingues Lanclos Jan 2001

Parenting Practices As A Moderator Of Exposure To Community Violence., Nicole Francingues Lanclos

LSU Historical Dissertations and Theses

Numerous studies evidence that urban youth are exposed to epidemic proportions of community violence. Exposure to community violence has been associated with significant levels of distress including aggression, academic difficulties, anxiety, depression, and posttraumatic stress disorder. Although it is clear that children who experience chronic levels of violence exposure are at increased risk for poor developmental outcome, the consequences of exposure are not the same for all children. Parenting factors found to buffer the effects of community violence exposure include family size, parental presence in the home, family support, parenting resources, family cohesion, and strong parental monitoring. It is less …

Biodegradation Of Desorption -Resistant Organic Contaminants In Wetland Soils., Sangjin Lee Jan 2001

Biodegradation Of Desorption -Resistant Organic Contaminants In Wetland Soils., Sangjin Lee

LSU Historical Dissertations and Theses

Contaminant bioavailability depends on physicochemical processes such as adsorption/desorption, diffusion, and dissolution. The rates of sorption and desorption of trichloroethylene (TCE) and 1,3-Dichlororbenzene (1,3-DCB) were studied. Desorption kinetics of 3-month and 5-month old contaminated soils showed that progressively less amount of contaminant was available for facile desorption compared to freshly contaminated soil in an empirical non-linear model. Microcosm batch studies were conducted to study the biodegradation of 1,3-DCB in the aqueous and soil phase containing a freshly contaminated soil and a soil containing only the desorption resistant fraction. The presence of the soil reduced the rates of biodegradation. It is …

Show Me The Money: An Analysis Of The Impact Of Voter Recognition On The Campaign Spending Effects Of House And Senate Candidates., Nicholas Chad Long Jan 2001

Show Me The Money: An Analysis Of The Impact Of Voter Recognition On The Campaign Spending Effects Of House And Senate Candidates., Nicholas Chad Long

LSU Historical Dissertations and Theses

The focus of this dissertation is campaign spending in congressional elections. I examine the benefits that candidates receive from campaign expenditures. I think that challengers receive greater benefits from spending than incumbents, but that the extent of these benefits depends on the type of challenger. High-quality challengers are those that have previous experience in an important elective office, while low-quality challengers lack this experience. Because of this experience, high-quality challengers enjoy a higher level of recognition among the electorate than low-quality challengers. I think that the benefits that challengers receive from expenditures are inversely related to the level of recognition …

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire Jan 2001

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire

LSU Historical Dissertations and Theses

The Great White Heron was originally described as a distinct species (Ardea occidentalis), but is currently considered to be the white morph of a polymorphic Great Blue Heron subspecies (A. herodias occidentalis). Great White and Great Blue heron breeding ranges overlap in the Florida Keys (USA), providing an opportunity to evaluate the degree to which these two taxa are reproductively isolated. The current classification leads to predictions of no significant size difference (H01), random mate choice (H02), and no genetic divergence (H03) between sympatric white and blue herons. Sympatric Great White and Great Blue herons did not differ significantly in …

Systematics Of Neotropical Satyrine Butterflies (Nymphalidae: Satyrinae: Euptychiina) Based On Larval Morphology And Dna Sequence Data And The Evolution Of Life History Traits., Debra Lynne Murray

LSU Historical Dissertations and Theses

Although satyrine butterflies (Lepidoptera: Nymphalidae: Satyrinae) are highly diverse and found worldwide in most terrestrial habitats, they have received little attention from systematists. This research focuses on one of the largest satyrine groups, the euptychiines, found from central United States to Argentina, with the greatest diversity in the Amazon. The subtribe Euptychiina has a troubled taxonomic history. Most genera were erected without diagnoses and placed within the subtribe without being examined. Before this project was initiated, little was known of their basic biology and morphology. Therefore, considerable attention was given to this area in my research. I describe the larvae …
