Phenotypic Plasticity May Facilitate Invasion By Aegilops Triuncialis, Andrew R. Dyer

Faculty Publications

One great obstacle to understanding the invasion of nonnative species into native ecosystems is the lack of information on the population biology of the invading species. In particular, morphological and physiological adaptations and potential for phenotypic plasticity will strongly influence a species’ ability to persist and spread in newly invaded ecosystems. Phenotypic plasticity can buffer populations from selection thereby allowing them to survive the establishment phase of the invasion. The annual grass Aegilops triuncialis (Poaceae, Triticeae) has become highly invasive in California (USA) and provides an opportunity to investigate the importance of phenotypic plasticity to persistence and spread in new …

Jonas Kamlet (1914-1960) Chemist/Entrepreneur, Dean F. Martin, Barbara B. Martin

Chemistry Faculty Publications

Jonas Kamlet, Ph.D., as a chemist, inventor, and a significant entrepreneur who founded Kamlet Laboratories in New York City that became the model of a successful consulting firm. Among his hundreds of patents and inventions were a tablet that could be used to measure glucose in urine, a treated strip that could detect pregnancy, a fodder for ruminants that used newsprint, and biuret (a self-condensation product of urea) that could be used as a non-protein component of fodder. Following his death in an airplane collision on December 16, 1960, his wife and collaborator (and later a resident of Florida) carried …

Introductory Lectures On Turbulence: Physics, Mathematics And Modeling, James M. Mcdonough

Mechanical Engineering Textbook Gallery

From Chapter 1:

The understanding of turbulent behavior in flowing fluids is one of the most intriguing, frustrating— and important—problems in all of classical physics.

The problem of turbulence has been studied by many of the greatest physicists and engineers of the 19th and 20th Centuries, and yet we do not understand in complete detail how or why turbulence occurs, nor can we predict turbulent behavior with any degree of reliability, even in very simple (from an engineering perspective) flow situations. Thus, study of turbulence is motivated both by its inherent intellectual challenge and by the practical utility of a …

A Role For The Cytoskeleton In Heart Looping, Kersti K. Linask, Michael Vanauker

Chemical, Biological and Materials Engineering Faculty Publications

Over the past 10 years, key genes involved in specification of left-right laterality pathways in the embryo have been defined. The read-out for misexpression of laterality genes is usually the direction of heart looping. The question of how dextral looping direction occurred mechanistically and how the heart tube bends remains unknown. It is becoming clear from our experiments and those of others that left-right differences in cell proliferation in the second heart field (anterior heart field) drives the dextral direction. Evidence is accumulating that the cytoskeleton is at the center of laterality, and the bending and rotational forces associated with …

Secondary Special Education: A Comparative Study Of Teachers Of "High Incidence Disabilities", Leah Wasburn-Moses, Emily C. Bouck

Mid-Western Educational Researcher

Although state education agencies, teacher preparation institutions, and public schools often combine high incidence disabilities into one category and one placement, the students grouped under this label often have diverse educational needs. This study compares two samples of secondary special education teachers working at the same schools to examine programming across disability category. One sample consists of teachers of students with learning disabilities (LD) and the other, teachers of students with mild mental impairments (MMI). The paper compares the similarities and differences.

The Importance And Influence Of Groundwater Fluctuations In Phytoremediation, Jeff A. Weishaar

Masters Theses

"The primary purpose of this research is to study the relationship between microbial degradation and plant uptake of volatile hydrocarbons, such as benzene, toluene, ethylbenzene and xylene. While these compounds are known to biodegrade and are capable of transport into plant tissue, any relationship between the two removal mechanisms remains largely unknown. The goal of this work is to better understand the interactions of these multiple biological processes within a phtytoremediation effort"--Introduction, page 3.

Medical Futility Statutes: No Safe Harbor To Unilaterally Refuse Life-Sustaining Treatment, Thaddeus Mason Pope

Faculty Scholarship

Over the past fifteen years, a majority of states have enacted medical futility statutes that permit a health care provider to refuse a patient's request for life-sustaining medical treatment. These statutes typically permit the provider to unilaterally stop LSMT where it would not provide significant benefit or would be contrary to generally accepted health care standards. But these safe harbors are vague and imprecise. Consequently, providers have been reluctant to utilize these medical futility statutes.

This uncertainty probably cannot be reduced. Consensus on substantive measures of medical inappropriateness has proven unachievable. Only a purely process-based approach like that outlined in …

Consumers And Citizens In The Global Agrifood System: The Cases Of New Zealand And South Africa In The Global Red Meat Chain, Keiko Tanaka, Elizabeth Ransom

Sociology and Anthropology Faculty Publications

This chapter aims to show that the process of changing rules within the capitalist market system, specifically meat safety governance reform in New Zealand and South Africa, raises profound obstacles for human agency, yet opens new spaces for conceptualizing who participates in promoting change. Agency and structure are complex concepts with dueling tensions that alter the form and substance (as Wright and Middendorf argue in their Introduction to this volume) of individual and collective action in the red meat commodity chains of these two countries. We show that, far from being monolithic, the ways in which capitalism and a changing …

A Tale Of Two Priests And Two Struggles: Liberation Theology From Dictatorship To Democracy In The Brazilian Northeast, Jan Hoffman French

Sociology and Anthropology Faculty Publications

Land for the landless, food for the hungry, literacy for the uneducated— not through charitable works, but by forcing the state to take seriously its responsibilities to its poorest citizens. This was integral to the theology of liberation as it was practiced by bishops, priests, and nuns in Brazil beginning shortly after the close of the Second Vatican Council in 1965. Important sectors of the Brazilian Catholic Church were “opting for the poor” at a time when economic development, modernization, and democracy were not considered appropriate or meaningful partners in the repressive environment characterized by the Brazilian military dictatorship (1964-1985).

Novelty, Arousal, And Love: The Mediating Role Of Self -Expansion, Amy Deloyski

All-Inclusive List of Electronic Theses and Dissertations

There is a substantial amount of evidence for a decline in feelings of passionate love across the course of intimate relationships (Aron, Norman, & Aron, 2001). Self-expansion theory (Aron & Aron, 1986) posits that individuals enter into relationships to expand their sense of self and suggests that declines in feelings of passionate love are due to diminished opportunities for expansion with one's partner over time. Previous researchers have been able to create increases in relationship quality by having partners engage in joint participation in novel and arousing activities, which are considered a basis for self-expansion (Aron, et al., 2000). The …

Perceived Stress Among First -Year Students At A Private, Faith-Based College, Ron L. Coffey

All-Inclusive List of Electronic Theses and Dissertations

This study examines stress in first-year college students at a faith-based institution and to determine whether social support, gender, involvement in intercollegiate athletics, academic achievement, or religiosity were factors that affect or buffer the negative effects of stress. Using data collected from approximately 200 first-year students at a Midwestern faith-based institution, the study investigated particular student and social support factors that may be associated with the kind of stress that can prevent students from achieving to their potential. Internal-reliability tests and factor analyses revealed two distinct forms of stress, one labeled internally-sourced stressors and the other externally-sourced stressors. Regressing the …

The Fourth R: How Indiana Public School Superintendents Make Decisions About Religious Issues, Esselona Jane Larson

All-Inclusive List of Electronic Theses and Dissertations

The purpose of this qualitative study was to understand how Indiana public school superintendents make decisions about religious issues. Although laws are written specifically to address religion and its relationship in public schools, the interpretation of these laws is affected by different factors in the public school arena. The participants in this study were nine Indiana public school superintendents, male and female from all regions of the state, representing different locale, gender, ethnicity, age and years of experience. During the literature review, six categories emerged: religion and curriculum, equal access to school facilities, prayer in schools, religious accommodations, free speech …

The African Lungfish (Protopterus Dolloi): Ionoregulation And Osmoregulation In A Fish Out Of Water, Michael P. Wilkie, Tammie P. Morgan, Fernando Galvez, Richard W. Smith, Makiko Kajimura, Yuen K. Ip, Chris M. Wood

Faculty Publications

Although urea production and metabolism in lungfish have been thoroughly studied, we have little knowledge of how internal osmotic and electrolyte balance are controlled during estivation or in water. We tested the hypothesis that, compared with the body surface of teleosts, the slender African lungfish (Protopterus dolloi) body surface was relatively impermeable to water, Na +, and Cl- due to its greatly reduced gills. Accordingly, we measured the tritiated water (3H-H2O) flux in P. dolloi in water and during air exposure. In water, 3H-H2O efflux was comparable with the lowest measurements reported in freshwater teleosts, with a rate constant (K) …

Sex, Seasonal, And Stress-Related Variations In Elasmobranch Corticosterone Concentrations, Charles A. Manire, L. E.L. Rasmussen, Karen P. Maruska, Timothy C. Tricas

Faculty Publications

Serum corticosterone was previously studied in numerous elasmobranch fishes (sharks, skates and rays), but the role of this steroid, widespread throughout many taxa, has yet to be defined. The goal of this study was to test whether corticosterone varied in response to acute and chronic capture stress, and across the reproductive cycle in the bonnethead shark, Sphyrna tiburo, and Atlantic stingray, Dasyatis sabina. Serum corticosterone in S. tiburo increased following capture and again 24 h post-capture, possibly caused by interference with 1α-hydroxycorticosterone, the primary stress hormone in elasmobranchs. Higher serum concentrations in males compared to females were observed in both …

Sex And Seasonal Co-Variation Of Arginine Vasotocin (Avt) And Gonadotropin-Releasing Hormone (Gnrh) Neurons In The Brain Of The Halfspotted Goby, Karen P. Maruska, Mindy H. Mizobe, Timothy C. Tricas

Faculty Publications

Gonadotropin-releasing hormone (GnRH) and arginine vasotocin (AVT) are critical regulators of reproductive behaviors that exhibit tremendous plasticity, but co-variation in discrete GnRH and AVT neuron populations among sex and season are only partially described in fishes. We used immunocytochemistry to examine sexual and temporal variations in neuron number and size in three GnRH and AVT cell groups in relation to reproductive activities in the halfspotted goby (Asterropteryx semipunctata). GnRH-immunoreactive (-ir) somata occur in the terminal nerve, preoptic area, and midbrain tegmentum, and AVT-ir somata within parvocellular, magnocellular, and gigantocellular regions of the preoptic area. Sex differences were found among all …

Decoupling Natural And Anthropogenic Fire Regimes: A Case Study In Everglades National Park, Florida, Matthew G. Slocum, William J. Platt, Brian Beckage, Bob Panko, James B. Lushine

Faculty Publications

Anthropogenic fire regimes obscure natural fire regimes, reducing the ability to manage fire-frequented habitats ecologically. To address this problem, we attempted to decouple natural and anthropogenic fire regimes by comparing them to seasonal climatic patterns and landscape characteristics in Everglades National Park (1948-1999). Of the total area burned by lightning fires, 57% resulted from ignitions seven days within onset of the wet season, 11% from ignitions starting 7-21 days before onset, and 36% from ignitions > 7 days after onset. In contrast, of the total area burned by incendiary fires, 89% resulted from ignitions > 7 days before onset, and 40% resulted …

Outside Inside Out: Perspectives On Social Anxiety, Kevin Andrew Hagan

LSU Master's Theses

“Outside Inside Out” is a study of how the visual perspective of an installation design can be used to create interaction, animation, and multiple messages. Traditionally, graphic designers have tended to present their messages either as flat printed materials, such as newspapers and billboards, or as videos/animations on television and the Internet. While both of these mediums provide an adequate means to convey a message, they fall short in presenting information to the audience in a non-obtrusive, interactive form. By using a technique I developed called “Passive Interactivity,” designers can use a viewer’s visual perspective to create interaction, animation, and …

Descriptions Of Soronia Complex (Coleoptera: Nitidulidae: Nitidulinae) Larvae Of New Zealand With Comments On Life History And Taxonomy, Chris Carlton, Richard A.B. Leschen

Faculty Publications

We provide the first descriptions of larvae of the nitidulid beetles Soronia oculata Reitter and Hisparonia hystrix (Sharp), compare them with similar larvae of other nitidulids, and comment on the utility of larval data in phylogenetic studies. Soronia oculata larvae are quite similar to many other larvae within the Soronia genus complex, but those of H. hystrix are distinctly different, namely by having an unfringed, spinose mandibular prostheca, striations of mola obscured by blunt teeth, and malar setae that are course and restricted to the distal half. This supports the recent transfer of the species to a monotypic genus. Larvae …

Conservation Of The Brca1 Gene, Matthew Gary Wronkowski

Theses

Most research has been conducted on the structure and function of many individual genes as well as complementary proteins. Many of these studies look at specific population groups' country of origin, geographic location, or ethnicity but do not correlate findings between these groups. In this project I attempted to associate the structural and functional consequences of individual mutations in Human BRCA1 to other organisms. My findings suggest a strong correlation between human geographical isolation and mutation exclusivity. Furthermore strong sequence and mutation conservation as well as structural homology exist between many species.
