Uncontrollable And Unpredictable Stress With A Reminder Experience Induces Long-Lasting Effects On Physiology And Behavior: A Novel Approach To Modeling Post-Traumatic Stress Disorder In Rats, Phillip R. Zoladz

USF Tampa Graduate Theses and Dissertations

People who endure horrific, life-threatening experiences are at risk for developing post-traumatic stress disorder (PTSD). However, only about 25% of all individuals who experience trauma develop PTSD. Recent research indicates that the presence of certain physiological conditions, such as reduced cortisol and parasympathetic inhibition, during trauma may increase one's susceptibility to developing PTSD. Thus, I attempted to develop a novel animal model of PTSD and test the hypothesis that reduced adrenal and parasympathetic activity during stress would exacerbate its long-term effects on behavior.

In Experiment One, adult male rats were exposed to two stress sessions, each involving one hour of …

Chronic-Alcohol Exposure Alters Igf1 Signaling In H9c2 Cells Via Changes In Pkc Delta, Richard Ila, Michele Solem

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Previously, we have demonstrated that chronic-alcohol exposure alters insulin-like growth factor 1 (IGF1) signaling in adult rat heart cells. This report examines the effects of alcohol in vitro on the expression of protein kinase C (PKC) alpha, delta, and epsilon using the embryonic heart cell line, H9c2, and how this may be linked to changes in IGF1 signal transduction. Western blot analyses of H9c2 protein preparations demonstrate that there are significant increases in the total protein levels of PKC delta and epsilon after 4 days exposure to alcohol, and similar increases were found after 2 and 6 days exposure. In …

Official Representations Of The Nation: Comparing The Postage Stamps Of Sudan And Burkina Faso, Michael Kevane

Economics

An analysis of the imagery on postage stamps suggests that regimes in Burkina Faso and Sudan have pursued very different strategies in representing the nation. Sudan's stamps focus on the political center and dominant elite (current regime, Khartoum politicians, and Arab and Islamic identity) while Burkina Faso's stamps focus on society (artists, multiple ethnic groups, and development). Sudan's stamps build an image of the nation as being about the northern-dominated regime in Khartoum (whether military or parliamentary); Burkina Faso's stamps project an image of the nation as multi-ethnic and development-oriented.

The Eastern Lowland Gorilla: Saving The Victims Of Coltan, Amy Costanzo

ExpressO

This article addresses the demand for coltan and the effects of this demand on the Eastern Lowland Gorilla, a species of great ape residing largely in the Democratic Republic of the Congo, home to greatest coltan reserves in the world. The growing demand for coltan has had a devastating effect on this animal, which includes habitat destruction, gorillas being killed for bushmeat, and baby gorillas being orphaned or sold as pets.

It addresses the international agreements, including CITES and the Convention on Biological Diversity, that have already been passed in an effort to help save the Eastern Lowland Gorilla, among …

Reassessing Damages In Securities Fraud Class Actions, Elizabeth C. Burch

ExpressO

No coherent doctrinal statement exists for calculating open-market damages for securities fraud class actions. Instead, courts have tried in vain to fashion common-law deceit and misrepresentation remedies to fit open-market fraud. The result is a relatively ineffective system with a hallmark feature: unpredictable damage awards. This poses a significant fraud deterrence problem from both a practical and a theoretical standpoint.

In 2005, the Supreme Court had the opportunity to clarify open-market damage principles and to facilitate earlier dismissal of cases without compensable economic losses. Instead, in Dura Pharmaceuticals v. Broudo, it further confused the damage issue by (1) perpetuating the …

A Tragic Farce: Revolutionary Women In Elizabeth Inchbald’S The Massacre And European Drama, Wendy Nielsen

Department of English Faculty Scholarship and Creative Works

This essay examines Elizabeth Inchbald’s treatment of French Revolutionary women and relationship to European drama in order to appreciate the implications of tragic writing for British women playwrights. Focusing on Inchbald’s connections to French culture and English theater in late 1792 and early 1793 elucidates the self‐censoring and generic conventions of her only tragedy, The Massacre. Events in France like the September Massacres unsettled Burkean notions of femininity and raised the possibility of female violence. This mixing of traditional gender characteristics resembles discourse about Inchbald’s dramas as neither tragic, comic, nor tragicomic. The genre of tragic farce describes Inchbald’s revisions …

Closure Of Earthern Manure Structures (Including Basins, Holding Ponds And Lagoons), Don D. Jones, Richard K. Koelsch, Saqib Mukhtar, Ronald Sheffield, John W. Worley

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

This paper is a summary of what is known scientifically about the closure of earthen manure structures without artificial liners, including lagoons, storage basins, and runoff holding ponds, and what needs to be examined further to increase our understanding of the dynamics of closing them in an environmentally safe manner. This information should be useful as a guide for state regulatory agencies considering rules for closure and for academicians and consultants who work with livestock production facilities.

The Story Of Me: The Underprotection Of Autobiographical Speech, Sonja R. West

ExpressO

This article begins the debate over the constitutional underprotection of autobiographical speech. While receiving significant historical, scientific, religious and philosophical respect for centuries, the time-honored practice of talking about yourself has been ignored by legal scholars. A consequence of this oversight is that current free speech principles protect the autobiographies of the powerful but leave the stories of “ordinary” people vulnerable to challenge. Shifting attitudes about privacy combined with advanced technologies, meanwhile, have led to more people than ever before having both the desire and the means to tell their stories to a widespread audience. This article argues that truthful …

The Capabilities Approach As A Solution To The Need For A More Encompassing Definition Of Poverty, Sarah L. Harrington

ExpressO

This Comment addresses the historical and present manifestations that result from the lack of values reflected in the federal poverty line. An alternative to this measure may be based on the capabilities approach. This approach looks further than simply the means to equality, and instead focuses on the ends--that is achieving well-being, and the freedom to pursue well-being. The capabilities approach is further described through an example of an effort to operationalize the theory by the United National Development Programme. Ultimately, this Comment proposes that renewed attention be focused on reforming the federal poverty line in light of the philosophical …

Standing For Extraterritoriality: Defining The Empagran Exception, Max Huffman

ExpressO

Efforts by private plaintiffs to enforce the U.S. antitrust laws extraterritorially have become an enormous industry. A reflection of the challenges facing federal courts in this global age, F. Hoffman-LaRoche Ltd. v. Empagran S.A. (Empagran) held the Foreign Trade Antitrust Improvements Act of 1982 (FTAIA) precluded the assertion by U.S. courts of jurisdiction over claims by foreign plaintiffs alleging harm felt in wholly foreign commerce.

Empagran left an exception that undermines its general rule. Plaintiffs able sufficiently to show “the anticompetitive conduct’s domestic effects were linked to their foreign harm” are excepted from the preclusion. This is the “Empagran exception.” …

The Pocahontas Exception: The Exemption Of American Indian Ancestry From Racial Purity Law, Kevin Noble Maillard

ExpressO

“The Pocahontas Exception” confronts the legal existence and cultural fascination with the eponymous “Indian Grandmother.” Laws existed in many states that prohibited marriage between whites and nonwhites to prevent the “quagmire of mongrelization.” Yet, this racial protectionism, as ingrained in law, blatantly exempted Indian blood from the threat to white racial purity. In Virginia, the Racial Integrity Act of 1924 made exceptions for whites of mixed descent who proudly claimed Native American ancestry from Pocahontas. This paper questions the juridical exceptions made for Native American ancestry in antimiscegenation statues, and analyzes the concomitant exemptions in contemporary social practice. With increasing …

The deminer stated that the two mines that he had found earlier that day had only been 5cm deep, and that he did not expect to find another mine so close to the last one [even though the previous three had been with 2 metres of each other], or so deep; he therefore assumed that the signal was not a mine. He thinks that the mine was deeper than 10cm below the surface. He accepts that he may have exerted too much pressure whilst excavating.

Remotely Accessible Hardware-In-The-Loop Robot Simulator, Ali Turan

Engineering

In this thesis, a novel and remotely accessible hardware-in-the-loop simulator (HILS) is developed for the real-time simulation of a variety of robotic systems for on-site and remote education and research. In that sense, the thesis contributes to the first known application of the HILS concept in the field of robotics and mechatronics that is remotely accessible. The HILS set-up incorporates most of the crucial hardware that takes part in the actual mechatronics/robotics system, thus enabling a more realistic simulation of the dynamics and control than would be possible with computer simulations. Any given robotic configuration can be simulated by using …

Acacia Constricta Gains Novel Benefits From Ants While Minimizing Potential Conflicts, E. Fleur Nicklen

Biological Sciences

The sum of costs and benefits in an interspecific interaction determines whether the relationship is mutualistic, neutral, or antagonistic. We investigate novel benefits Acacia constricta may gain from ant visitors and how A. constricta may minimize potential costs of ant visitation. A. constricta attracts ants onto its foliage and encourages nesting at its base with extrafloral nectaries. Plants with basal nests have significantly greater soil nutrients and produce twice as many seeds as plants lacking basal nests (Wagner 1997). Along side these benefits, however, ants can interfere with plant reproduction. This study tests whether augmented soil nutrients increase A. constricta's …

Seasonal Changes In The Rumen Microbial Ecology Of Muskoxen, Annie R. Crater

Biological Sciences

Ruminal fermentation must respond to seasonal changes in the behavior and digestive function of muskoxen (Ovibos moschatus) as intakes of food and water rise in autumn (August - October) and decline from winter to spring (November - May). Rumen temperatures were not static but instead were punctuated by decreases of as much as 13°C below the average of 39°C. Declines in rumen temperature were associated with water ingestion while gains in rumen temperature were associated with feeding. Food intake and water turnover rates were positively correlated. Direct microscopic counts of bacteria in rumen fluid decreased from 1.8 to 0.9 X …

Population Genetic Structure And Phylogeography Of Common Eiders (Somateria Mollissima), Sarah A. Sonsthagen

Biological Sciences

Population genetic structure of Common Eiders (Somateria mollissima) was assessed at increasing spatial scales (microgeographic [<1 km] to throughout their circumpolar distribution), using molecular markers with varying modes of inheritance and rates of evolution. Population genetic subdivision was observed at all spatial scales; however, the degree of structure differed among marker types. Relatively lower levels of spatial genetic structuring were observed at bi-parentally inherited markers, and high levels of structuring were observed at a maternally inherited locus. Differences in the degree of subdivision between marker types may be attributable to the breeding biology of eiders. Pair formation occurs on the wintering grounds; where several populations of eiders interact. Female eiders exhibit high natal and breeding philopatry; whereas, males accompany females back to breeding sites and may disperse long distances between breeding seasons. Significant structuring observed at microgeographic scales indicates that eiders may nest in kin groups. Though the underlying mechanism enabling female eiders to discriminate kin is unknown, waterfowl may achieve kin recognition indirectly through association during brood rearing. Genetic signatures of philopatry among Common Eider populations do vary among Alaskan populations. No genetic structuring at mitochondrial DNA (mtDNA) was observed among islands in the Beaufort Sea in close geographic proximity (1-49 km apart). However, high structuring was observed among island groups, suggesting females are philopatric to island groups rather than individual islands. In contrast, moderate levels of genetic partitioning for mtDNA were observed among Yukon-Kuskokwim Delta (YKD) colonies (9-63 km apart); therefore, female eiders may be philopatric to individual colonies. MtDNA haplotypes representing Aleutian and YKD populations are more genetically similar to Canadian and Scandinavian populations than northern Alaska populations, indicating that southern Alaskan populations were colonized from central Canadian refugia. Data indicate that the North Slope may have been a refugium for eiders but contributed little to the post-glacial colonization of North America and Scandinavia. Finally, philopatry and winter site fidelity observed in waterfowl have predictable effects on population genetic structure. Researchers characterizing populations using molecular techniques could under- or over-estimate the degree of population genetic differentiation if estimates are based on a single marker type.

The Illusion Of Knowledge: The Evolution Of Early Cartographic Conceptions Of Alaska, Neva Sherman

Arctic and Northern Studies

The evolution of early cartographic conceptions of Alaska is marked by rises and falls in the advancement of knowledge, due to factors including the power of cartographers to perpetuate geographic speculation, unsuccessful expeditions of exploration, bureaucratic policies of secrecy, and purposeful deceit. This thesis examines that evolution, from the first appearance of western North America on world maps in the sixteenth century, through Russian expeditions to the region, to Captain James Cook's accurate mapping of the extent of Alaska in the eighteenth century, analyzing the factors that influenced Alaska's cartographic depictions and the real-life implications of those depictions. The maps …

A Model-Based Design Tool For Systems-Level Spacecraft Design , Brandon Eames, Allan Mcinnes, Jared Crace, Joe Graham

Small Satellite Conference

It is standard practice to mathematically model and analyze the various subsystems that make up a spacecraft, to ensure that they will function correctly when built. However, the system-level behavior of the spacecraft is generally understood in much less rigorous terms. This leaves the spacecraft system far more vulnerable than the subsystems to unforeseen design errors which may not manifest themselves until the integration and test phase, when design changes are most expensive in terms of cost and schedule. In this paper, we present Spacecraft Design Workbench, an extensible graphical design tool built upon the Generic Modeling Environment (GME) tool …

Attitude Control Strategy For Hausat-2 With Pitch Bias Momentum System, Young-Keun Chang, Seok-Jin Kang, Byung-Hoon Lee, Jung-Won Choi, Mi-Yeon Yun, Byoung-Young Moon

Small Satellite Conference

The HAUSAT-2 is a 25kg class micro/nanosatellite which is being developed by graduate students at the Space System Research Laboratory(SSRL). This paper addresses a newly proposed strategy for detumbling the HAUSAT-2 and starting up a momentum wheel, and also studies performance validation and application ranges of such method through simulation. B-dot logic is generally used for controlling the initial tip-off rate. However, it has the disadvantage of taking a relatively long time to control the initial tip-off rate. To solve this problem, this paper suggests a new detumbling control method to be able to adapt to micro/nanosatellite with the pitch …

Fpga Based Attitude Control System Architecture For Increased Performance, Georg Grillmayer, Marc Hirth, Felix Huber, Viola Wolter

Small Satellite Conference

For micro-satellites the required attitude accuracy, agility and autonomy along with desired parallel processing of payload images in real-time needs to be achieved within limited power and computational resources. Providing fast, parallel execution while still small in hardware size and modest in power consumption field programmable gate array (FPGA) based on-board computers (OBC) have the potential to highly increase system performance. The Flying Laptop is a micro-satellite currently under development at the Institute of Space Systems, Universität Stuttgart. The attitude control system together with the on-board navigation system is implemented as hardware in an FPGA. The architecture including the sensors, …

British National Parks For North Americans: What We Can Learn From A More Crowded Nation Proud Of Its Countryside, Federico Cheever

ExpressO

England and Wales contain twelve national parks coverings more than 10 percent of their landscape. Although these parks are managed as national resources, the vast majority of the land within their borders is privately owned. Although they are managed to preserve their natural qualities, they contain farms, towns and roughly 300,000 people. They contain nothing North Americans would consider wilderness. Although recognized national assets, nationally funded, they are administered by boards made up largely of local representatives. Since passage of the National Parks and Access to Countryside Act of 1949, the British have managed to develop a national park system …

The Right To Roam, Jerry L. Anderson

ExpressO

In 2000, Britain enacted a “right to roam” in the Countryside and Rights of Way Act (CRoW). At first glance, CRoW appears to be a dramatic curtailment of the landowner’s traditional right to exclude: it opens up all private land classified as “mountain, moor, heath, or down” to the public for hiking and picnicking. Yet, when viewed in the light of history, CRoW may be seen as partially restoring to the commoner rights lost during the enclosure period, when the commons system ended. CRoW also represents a return to a functional rather than spatial form of land ownership, allowing more …
