Breeding Waterbird Use Of Rice Fields In Southwestern Louisiana, Sergio Pierluissi

LSU Master's Theses

Rice fields are agricultural wetlands concentrated in several areas in the U.S., including southwestern Louisiana. Rice fields are flooded for much of the year and support thick emergent vegetation, potentially providing high-quality habitat for several species of breeding waterbirds. The objectives of this study were to (1) determine relative nest density, nest success, and habitat associations of breeding waterbirds in southwestern Louisiana rice fields and (2) determine the effectiveness of callback surveys as a monitoring tool. In the summers of 2004 and 2005, marsh bird surveys and nest searches were conducted in Cameron, Jefferson Davis, Vermilion, and Acadia Parishes in …

Effects Of Insectivorous Birds On Tree Growth In The Maurepas Swamp, David M. Fox

LSU Master's Theses

Coastal forests in Louisiana are in decline due to natural and human caused changes in the hydrology of the region. Baldcypress and water tupelo trees have been further stressed by caterpillar herbivory in recent decades. Regeneration of water tupelo is crucial for cavity creation for nesting habitat for secondary cavity nesting bird populations. Insectivorous birds have been shown to decrease insect-caused leaf damage on trees in other ecosystems. Two experiments examining effects of insectivorous birds on tree growth were conducted in degraded areas of the Maurepas Swamp in southeastern Louisiana. In the first experiment, nest boxes were added to study …

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 …

Escape To Utopia: Mental Illness, Veterans, And Gowanda State Hospital (1946-1952), Ursula Irene Anna Goldsmith

LSU Master's Theses

This study will cover the history from 1946 to 1952 of a state hospital located in Helmuth, New York, known as Gowanda State Homeopathic Hospital (GSH). It describes the community, physical campus and the surrounding area where it is located. The experience of treating military personnel suffering from combat-related mental illness during the 1940s led many psychiatrists to emphasize the social dimensions of mental disorder and to hypothesize that mentally ill civilians and veterans may best be treated outside of traditional mental institutions in their hometowns. This theory was implemented with the discovery of psychotropic drugs in the mid 1950s. …

Rice Processing: Milling And Value-Added Effects, Rebecca C. Schramm

LSU Master's Theses

The ultimate goal of this research is to characterize data from the laboratory, pilot, and industrial scale rice mills. Pilot and laboratory scale data are presented in this research. Two long grain rice cultivars were milled with two different scale mills. Cheniere and Cypress were milled with a McGill No. 2 mill and a pilot scale mill (Satake). Both material streams, rice kernels and bran, were collected and weighed. Measurements of Degree of milling, transparency, and whiteness were made with a milling meter (Satake). Yield and bran fraction were calculated. Samples of the bran were heat stabilized and prepared for …

River, Tidal And Wind Interactions In A Deltaic Estuarine System, Gregg Snedden

LSU Doctoral Dissertations

The balance between river and marine influences is important in governing landscape sustainability in river deltas. River- and atmospherically driven sea level variability, sediment loading, and estuary-ocean exchange in the Mississippi River delta are examined in this study. Subtidal estuarine sea level variability in the Breton Sound estuary was driven by a combination of remote atmospheric forcing outside the estuary over the continental shelf and controlled river inputs through a gated diversion structure at the estuary head. The highly-frictional deltaic landscape acted as a low-pass filter to coastal fluctuations near the estuary mouth. When substantial quantities river water were discharged …

Retention And Transport Of Arsenic In Soils, Hua Zhang

LSU Doctoral Dissertations

Arsenic transport in soils and aquifers is highly dependent on the adsorption-desorption reactions in the solid phase. Results from our kinetic batch experiments indicated that adsorption of arsenate [As(V)] was highly nonlinear and strongly kinetic. Desorption of As(V) were hysteretic in nature and a significant amount of As(V) was irreversibly adsorbed on all soils. Results from column experiments indicated strong As(V) retardation followed by slow release or extensive tailing of the breakthrough curves (BTCs). Sharp decrease in As(V) concentration during flow interruption verified the extensive non-equilibrium condition which was likely due to the dominance of kinetic retention processes. We evaluated …

Synthesis, Characterization And Properties Of Cooper(Ii) Beta-Diketonate Macrocycles, Sylvester Burton

LSU Doctoral Dissertations

This dissertation deals with the synthesis and properties of multidentate β-diketone ligands and their transition-metal complexes. (1) We prepared two bis(β-diketones), C₁BAH₂ and p-XBAH₂ (see sketch below), determined their crystal structures, and studied their reactions with copper(II). We envisioned that they would form macrocyclic complexes with 3-6 metal atoms. In both cases, although the initial products are soluble, as expected for the desired molecular products, we were unable to isolate well-behaved molecular solids. In the case of C₁BAH₂, this may be because the cyclic product requires an unusual combination of conformations of …

Antimicrobial Activity Of Cpc And Asc Against Foodborne Pathogens And The Physiological Effect On Fresh-Cut Cantaloupe Cubes At Refrigerator Temperatures, Allison Marie Dumas

LSU Master's Theses

In the last few decades, fresh-cut fruit products have gained popularity with consumers. They require little to no further processing prior to consumption. Fresh-cut products also make fruits and vegetables more conveniently available to consumers year-round. There are limitations, however, to fresh-cut fruit and vegetables in the marketplace. These products are very perishable and could become contaminated with foodborne pathogens. Most fresh-cut fruits and vegetables will only last a short period of time at refrigerator temperatures. There are many possible routes of bacterial contamination in the fresh-cut produce industry. There is a need for antimicrobial compounds that can be applied …

Genetic Effects Influencing Salinity And Cold Tolerance In Tilapia, Alvaro M. Armas-Rosales

LSU Master's Theses

Genetic effects influencing salinity tolerance (ST) and cold tolerance (CT) were evaluated in two full diallel mating designs using six tilapia varieties: Oreochromis aureus (BL), O. mossambicus (MO), O. niloticus (NI), O. niloticus crossbreds (RE), Mississippi commercial strain (MC) and Florida red tilapia (FL). Statistical analyses provided estimates of direct heterosis (h_i), cross heterosis (h_ij), maternal effects (m_i), line effects (l_i), reciprocal and specific reciprocal effects (r_ij and r**_ij), and general and specific combining abilities (GCA and S_ij). Analysis of genetic effects for ST indicated that FL …

Gamete And Cell Technologies For Use In Biological Resource Banking, Liesl Nel-Themaat

LSU Doctoral Dissertations

Biological resource banking is becoming important for endangered species conservation. A series of experiments were conducted to address issues concerning collection and utilization of biomaterials from Gulf Coast Native (GCN) sheep (model species) (Ovis aries) and Eland antelope (Taurotragus oryx). In the first experiment, two ejaculates were collected 10 minutes apart from each of five rams three times a week for three weeks to maximize output and minimize handling time. Semen volume, concentration and total number of spermatozoa were significantly greater in first ejaculates, whereas pre-cooled, cooled and post-thaw motility, as well as sperm survival, were greater in second ejaculates. …

Determinants Of Local Calcium Signaling In Retinal Amacrine Cells, Madhumita Sen

LSU Doctoral Dissertations

Amacrine cells mediate complex lateral signaling in the inner plexiform layer of the vertebrate retina. Glutamate is the primary excitatory neurotransmitter that shapes the retinal circuitry by activating ionotropic glutamate receptors (iGluRs)and metabotropic glutamate receptors (mGluRs). One step in understanding the signaling in the inner retina is to understand the role and expression patterns of these glutamate receptors. The expression of iGluRs in amacrine cells is well documented in the literature. This study addresses the localization of Group I mGluRs in the retina. Pre-embedding immunocytochemistry combined with electron microscopy was used to study the expression of Group I mGluRs in …

Using The Rod: Education, Punishment, And The New Woman In Fin De Siã¨Cle British Literature, Kristin C. Ross

LSU Doctoral Dissertations

This study examines the relationship between female education and punishment in the British novel of the fin de siécle. It considers the “New Woman” (the emancipated, intellectualized, and unmarried prototypical feminist appearing in late nineteenth-century culture) in light of how female education affects fictional characterizations of her. Female education in the “New Woman” and her fictional counterparts worked to destabilize class and gender hierarchies for Victorian Society, producing anxiety in its culture and texts. To defuse this anxiety, authors frequently demonstrated the consequences of espousing the feminism driving the “New Woman” and the education producing her. The education she desired/received …

Contextualizing The Losses Of Allotment Through Literature, Kristen A. Carpenter

Publications

In this article, the Author undertakes a law and literature approach to a major Indian law problem: understanding the losses of allotment. Allotment was a mid 19th - early 20th century federal legislative program to take large tracts of land owned by Indian tribes, allocate smaller parcels to individual Indians, and sell off the rest to non-Indians. The idea was that Indians would abandon traditional patterns of subsistence to become American-style farmers, and great tracts of land would be freed up for the advance of white settlement. A key component of the federal government's larger project of assimilating Indians into …

Rethinking The Great Lakes Compact, Mark Squillace

Publications

On December 13, 2005, the Governors and Premiers of the Great Lakes states and provinces signed a Compact and Agreement that commits the parties to a rigorous program to regulate individual water uses, with citizen suits to enforce the requirements. While the Great Lakes-St. Lawrence River Basin Water Resources Compact and companion Agreement are commendable in many respects, this Article argues that people who care about the future of the Great Lakes should urge policymakers to reject the current proposals and rethink the entire approach. The proposed compact is fundamentally flawed and will not achieve the ultimate stated goal of …

Comparative Toxicosis Of Sodium Selenite And Selenomethionine In Lambs, A. K. Tiwary, B. L. Stegelmeier, K. E. Panter, L. F. James, Jeffery O. Hall

Animal, Dairy, and Veterinary Science Faculty Publications

Excess consumption of selenium (Se) accumulator plants can result in selenium intoxication. The objective of the study reported here was to compare the acute toxicosis caused by organic selenium (selenomethionine) found in plants with that caused by the supplemental, inorganic form of selenium (sodium selenite). Lambs were orally administered a single dose of selenium as either sodium selenite or selenomethionine and were monitored for 7 days, after which they were euthanized and necropsied. Twelve randomly assigned treatment groups consisted of animals given 0, 1, 2, 3, or 4 mg of Se/kg of body weight as sodium selenite, or 0, 1, …

Detection Of Early Stages Of Myxobolus Cerebralis In Fin Clips From Rainbow Trout (Onchorynchus Mykiss), Ramona T. Skirpstunas, J. Hergert, Thomas J. Baldwin

Animal, Dairy, and Veterinary Science Faculty Publications

A nested polymerase chain reaction (PCR) assay was used to detect early stages of Myxobolus cerebralis in caudal and adipose fin samples from rainbow trout (RT). To determine sensitivity, groups of 10 RT were exposed to 2,000 M. cerebralis triactinomyxons/fish for 1 hour at 15 degrees C and subsequently moved to clean recirculating water. Fish were held for 2 and 6 hours and 1, 2, 3, 5, 7, 10, 30, and 60 days before sampling by nonlethal fin biopsy. Nested PCR performed on fin clips showed that M. cerebralis DNA was detected in caudal fin tissue in 100% of fish …

Defining (Multiple) Selves: Reflections On Fieldwork In Jakarta, Chang Yau Hoon

Research Collection School of Social Sciences

The 'Self' in late-modernity is never singular but multiplies across different discourses, practices and positions. It is constructed through difference. It is only through a relation to the 'Other' that the 'Self' can be defined. This paper endeavours to map the endless negotiations of my 'Self' as male Australian academic of Chinese descent, a Malaysian citizen, a Bruneian resident, and an Indonesian specialist, over a period of fieldwork in Jakarta in 2004. It discusses how I defined my multiple 'Selves' to different individuals and communities, how they in turn defined me, and how these constructions were always shifting. Depending on …

Secure Digital Communication Using Chaotic Symbolic Dynamics, Ajeesh P. Kurian, Sadasivan Puthusserypady

Turkish Journal of Electrical Engineering and Computer Sciences

One of the major hurdles in implementing chaotic communication schemes is the synchronization of chaotic systems. For the last two decades, numerous contributions of varying successes have been made by researchers from different disciplines for the synchronization of chaotic systems. Symbolic dynamics based synchronization method is shown to be capable of providing high quality synchronization (HQS), which is essential for reliable communication. In this work, using this method, a secure digital communication system is proposed. The well known piece-wise linear 1-D map such as tent map and Bernoulli shift map are used for this study. Since the information is dynamically …

Penalty Defaults In Family Law: The Case Of Child Custody, Margaret F. Brinig

Journal Articles

This paper considers whether an amendment to state divorce laws that strengthens its joint custody preference operates as a traditional default rule, specifying what most divorcing couples would choose or as a penalty default rule the parties will attempt to contract around.

While the Oregon statutes that frame our discussion here, like most state laws, do not state an explicit preference for joint custody, shared custody is certainly encouraged by Section 107.179, which refers cases in which the parties cannot agree on joint custody to mediation and by Section 107.105, which requires the court to consider awarding custody jointly. In …

Rules Of Evidence For The Use Of Force In International Law's New Era, Mary Ellen O'Connell

Journal Articles

International law is ready for a period of renewal in this post-post-modern era. I predict this renewal will come from reviving classical doctrines, such as the positive-law doctrine of sources, and from revisiting formalism. Such renewal will not be possible for the international law of evidence because there is no classical doctrine. Perhaps, as Charles Brower suggests, this is because of the differing civil and common law attitudes toward the rules of evidence, especially with respect to the burden of proof. It seems to me, however, that we need a law of evidence in international law, especially for the international …
