Biological Sciences Faculty Publications

BioUD is an arthropod repellent that contains the active ingredient 2-undecanone originally derived from wild tomato plants. Repellency of BioUD was compared with five commercially available arthropod repellents against the ticks Amblyomma americanum (L.) and Dermacentor variabilis Say in two-choice bioassays on treated versus untreated cotton cheesecloth. Overall mean percentage repellency against both species was greatest for and did not differ significantly between BioUD (7.75% 2-undecanone) and products containing 98.1% DEET, 19.6% IR3535, and 30% oil of lemon eucalyptus. Products containing 5% and 15% Picaridin and 0.5% permethrin were also repellent compared with untreated controls but to a lesser degree …

Market-Based Asset Management And Shareholder Value: Investigating The Roles Of Human Capital And Factor Markets In Maximizing Returns On Customer Relationships, Chad Milewicz Jan 2009

Market-Based Asset Management And Shareholder Value: Investigating The Roles Of Human Capital And Factor Markets In Maximizing Returns On Customer Relationships, Chad Milewicz

Electronic Theses and Dissertations

The accountability of marketing investments continues to be a key area of concern for researchers and practitioners (MSI Research Priorities, 2008). In particular, market-based assets, specifically customer relationships, and their potential impact on firm performance are a significant source of interest. Though research in this area continues to grow, little is understood about how investments in human capital and the acquisition of alliance partners through factor markets relate to customer relationship management and the impact of customer relationships on performance. This dissertation presents two studies which, together, investigate how investments in market-based assets influence on abnormal stock returns. In the …

An Analysis Of Silver Candlesticks From A Casting Point Of View: Originals, Copies, Forgeries, Jaromir Audy, Emil Evin Jan 2009

An Analysis Of Silver Candlesticks From A Casting Point Of View: Originals, Copies, Forgeries, Jaromir Audy, Emil Evin

Research outputs pre 2011

Collecting silver artefacts has traditionally been a very popular hobby. Silver is addictive, therefore the number of potential collectors and investors appears to grow each year. Unfortunately, increases in the interest and buying potentials resulted in a number of forgeries manufactured and introduced to the open antique market. The items such as early silver candlesticks dictate a very high price, for many high quality fakes show very good appearances and matching similarities with originals. Such copies are traditionally manufactured by casting using the original items as patterns. Small details and variances in design features, position and shape of hallmarks, including …

Youth Harvest: Exploring An Employment-Based, Service-Oriented, Therapeutic Program For “At-Risk Youth”, Rachel Christine O'Brien Jan 2009

Youth Harvest: Exploring An Employment-Based, Service-Oriented, Therapeutic Program For “At-Risk Youth”, Rachel Christine O'Brien

Graduate Student Theses, Dissertations, & Professional Papers

In the mid-1990s, juvenile courts began establishing youth drug courts that blended the principles of restorative justice and the philosophy of therapeutic jurisprudence in an attempt to process juvenile drug offenders in a way that emphasizes rehabilitation of the offenders and restoration to the community. Over recent decades, wilderness therapy programs and horticultural therapy programs have become popular as alternative approaches for treating adjudicated and/or “at-risk” youth. The Youth Harvest program, which operates in conjunction with the Missoula Youth Drug Court, is a unique, therapeutic program that blends the goals of National Drug Courts and the principles of restorative justice …

The Politics Of Sectional Servitude : The Construction Of American Abolitionist Discourse In Black And White, 1837-1847, Christopher M. Florio Jan 2009

The Politics Of Sectional Servitude : The Construction Of American Abolitionist Discourse In Black And White, 1837-1847, Christopher M. Florio

Honors Theses

I argue that American political discourse surrounding abolition and slavery, sectional politics and violent insurrection, coalesced in the 1840s. The merger of such ostensibly disconnected streams of thought began with the perception of a new political need, as abolitionists came to believe that southern plantation elites had constructed a hegemonic proslavery order. Their interpretation of northern consent to southern domination impelled a proliferation of abolitionist possibilities, possibilities that were intended to sever the connection between national politics and the peculiar institution. Initially disseminated by freed blacks but subsequently appropriated by northern whites, these possibilities crossed the color line and challenged …

The C1 And C2 Domains Target Human Type 6 Adenylyl Cyclase To Lipid Rafts And Caveolae, Muthusamy Thangavel, Xiaoqiu Liu, Shu Qiang Sun, Joseph Kaminsky, Rennolds S. Ostrom Jan 2009

The C1 And C2 Domains Target Human Type 6 Adenylyl Cyclase To Lipid Rafts And Caveolae, Muthusamy Thangavel, Xiaoqiu Liu, Shu Qiang Sun, Joseph Kaminsky, Rennolds S. Ostrom

Pharmacy Faculty Articles and Research

Previous data has shown that adenylyl cyclase type 6 (AC6) is expressed principally in lipid rafts or caveolae of cardiac myocytes and other cell types while certain other isoforms of AC are excluded from these microdomains. The mechanism by which AC6 is localized to lipid rafts or caveolae is unknown. In this study, we show AC6 is localized in lipid rafts of COS-7 cells (expressing caveolin-1) and in HEK-293 cells or cardiac fibroblasts isolated from caveolin-1 knock-out mice (both of which lack prototypical caveolins). To determine the region of AC6 that confers raft localization, we independently expressed each of the …

Carbon And Nitrogen Stable Isotope Turnover Rates And Diet-Tissue Discrimination In Florida Manatees (Trichechus Manatus Latirostris), Christy D. Alves-Stanley, Graham A. J. Worthy Jan 2009

Carbon And Nitrogen Stable Isotope Turnover Rates And Diet-Tissue Discrimination In Florida Manatees (Trichechus Manatus Latirostris), Christy D. Alves-Stanley, Graham A. J. Worthy

Faculty Bibliography 2000s

The Florida manatee (Trichechus manatus latirostris) is a herbivorous marine mammal that occupies freshwater, estuarine and marine habitats. Despite being considered endangered, relatively little is known about its feeding ecology. The present study expands on previous work on manatee feeding ecology by providing critical baseline parameters for accurate isotopic data interpretation. Stable carbon and nitrogen isotope ratios were examined over a period of more than 1 year in the epidermis of rescued Florida manatees that were transitioning from a diet of aquatic forage to terrestrial forage (lettuce). The mean half-life for (13)C turnover was 53 and 59 days for skin …

Thermo-Mechanical Characterization Of High-Temperature Shape Memory Ni-Ti-Pd Wires, Matthew Fox Jan 2009

Thermo-Mechanical Characterization Of High-Temperature Shape Memory Ni-Ti-Pd Wires, Matthew Fox

Electronic Theses and Dissertations

Actuator applications of shape memory alloys have typically been limited by their phase transformation temperatures to around 100 degrees C. However, recently with a focus on aerospace and turbomachinery applications there have been successful efforts to increase the phase transformation temperatures. Several of these alloy development efforts have involved ternary and quaternary elemental additions (e.g., Pt, Pd, etc.) to binary NiTi alloys. Experimentally assessing the effects of varying composition and thermo-mechanical processing parameters can be cost intensive, especially when expensive, high-purity elemental additions are involved. Thus, in order to save on development costs there is value in establishing a methodology …

Beliefs Of Graduate Students About Unstructured Computer Use In Face-To-Face Classes With Internet Access And Its Influence On Student Recall, Gregory Johnson Jan 2009

Beliefs Of Graduate Students About Unstructured Computer Use In Face-To-Face Classes With Internet Access And Its Influence On Student Recall, Gregory Johnson

Electronic Theses and Dissertations

The use of computers equipped with Internet access by students during face-toface (F2F) class sessions is perceived as academically beneficial by a growing number of students and faculty members in universities across the United States. Nevertheless, some researchers suggest unstructured computer use detached from the immediate class content may negatively influence student participation, increase distraction levels, minimize recall of recently presented information, and decrease student engagement. This study investigates graduate students’ beliefs about computer use with Internet access during graduate face-to-face lecture classes in which computer use is neither mandated nor integrated in the class and the effect of such …

The Clash Of Thoughts Within The Arab Discourse, Chadia Louai Jan 2009

The Clash Of Thoughts Within The Arab Discourse, Chadia Louai

Electronic Theses and Dissertations

The Clash of Civilization thesis by Samuel Huntington and the claims of other scholars such as Bernard Lewis reinforced the impression in the West that the Arab world is a homogeneous and rigid entity ready to clash with other civilizations. In fact, some in the West argue that world civilizations have religious characteristics, for that reason the fundamental source of conflict in this new world will be primarily cultural and religious. However, other scholars argue that there is no single Islamic culture but rather multiple types of political Islam and different perception of it. Therefore, the monolithic aspect of Islam …

Game Assessment For Miltary Application, Patricia Mcneese Jan 2009

Game Assessment For Miltary Application, Patricia Mcneese

Electronic Theses and Dissertations

The primary purpose of conducting this research was to establish game assessment guidelines and characteristics for integrating elected characteristics of games into ongoing instructional approaches. The cost of repurposing commercial-off-the-shelf (COTS) games could offer a considerably lower cost alternative than the cost of creating a new instructional game developed for a specific instructional goal. The McNeese Game Assessment Tool (MGAT), created for the assessment of games in this usability study, is currently in a beta stage and was found to have potential for future game assessment. The overall assessment indicated that the tool was effective in analyzing game products for …

Habitat-Specific Breeder Survival Of Florida Scrub-Jays: Inferences From Multistate Models, David R. Breininger, James D. Nichols, Geoffrey M. Carter, Donna M. Oddy

Faculty Bibliography 2000s

Quantifying habitat-specific survival and changes in habitat quality within disturbance-prone habitats is critical for understanding population dynamics and variation in fitness, and for managing degraded ecosystems. We used 18 years of color-banding data and multistate capture-recapture models to test whether habitat quality within territories influences survival and detection probability of breeding Florida Scrub-Jays (Aphelocoma coerulescens) and to estimate bird transition probabilities from one territory quality state to another. Our study sites were along central Florida's Atlantic coast and included two of the four largest metapopulations within the species range. We developed Markov models for habitat transitions and compared these to …

The Longin Domain Regulates The Steady-State Dynamics Of Sec22 In Plasmodium Falciparum, Lawrence Ayong, Avanthi Raghavan, Timothy G. Schneider, Theodore F. Taraschi, David A. Fidock, Debopam Chakrabarti Jan 2009

The Longin Domain Regulates The Steady-State Dynamics Of Sec22 In Plasmodium Falciparum, Lawrence Ayong, Avanthi Raghavan, Timothy G. Schneider, Theodore F. Taraschi, David A. Fidock, Debopam Chakrabarti

Faculty Bibliography 2000s

The specificity of vesicle-mediated transport is largely regulated by the membrane-specific distribution of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins. However, the signals and machineries involved in SNARE protein targeting to the respective intracellular locations are not fully understood. We have identified a Sec22 ortholog in Plasmodium falciparum (PfSec22) that contains an atypical insertion of the Plasmodium export element within the N-terminal longin domain. This Sec22 protein partially associates with membrane structures in the parasitized erythrocytes when expressed under the control of the endogenous promoter element. Our studies indicate that the atypical longin domain contains signals that are required …

Mcp-1 (Monocyte Chemotactic Protein-1)-Induced Protein, A Recently Identified Zinc Finger Protein, Induces Adipogenesis In 3t3-L1 Pre-Adipocytes Without Peroxisome Proliferator-Activated Receptor Gamma, Craig W. Younce, Asim Azfer, Pappachan E. Kolattukudy Jan 2009

Mcp-1 (Monocyte Chemotactic Protein-1)-Induced Protein, A Recently Identified Zinc Finger Protein, Induces Adipogenesis In 3t3-L1 Pre-Adipocytes Without Peroxisome Proliferator-Activated Receptor Gamma, Craig W. Younce, Asim Azfer, Pappachan E. Kolattukudy

Faculty Bibliography 2000s

Adipogenesis is a key differentiation process relevant to obesity and associated diseases such as type 2 diabetes. This process involves temporally regulated genes controlled by a set of transcription factors, CCAAT/enhancer-binding proteins (C/EBP) beta, C/EBP delta, and C/EBP alpha and peroxisome proliferator-activated receptor gamma (PPAR gamma). Currently, PPAR gamma is universally accepted as the master regulator that is necessary and sufficient to induce adipogenesis as no known factor can induce adipogenesis without PPAR gamma. We present evidence that a novel zinc finger protein, MCP-1-induced protein (MCPIP), can induce adipogenesis without PPAR gamma. Classical adipogenesis-inducing medium induces MCP-1 production and expression …

Polyamine Transport As A Target For Treatment Of Pneumocystis Pneumonia, Chung-Ping Liao, Otto Phanstiel Iv, Mark E. Lasbury, Chen Zhang, Shoujin Shao, Pamela J. Durant, Bi-Hua Cheng, Chao-Hung Lee Jan 2009

Polyamine Transport As A Target For Treatment Of Pneumocystis Pneumonia, Chung-Ping Liao, Otto Phanstiel Iv, Mark E. Lasbury, Chen Zhang, Shoujin Shao, Pamela J. Durant, Bi-Hua Cheng, Chao-Hung Lee

Faculty Bibliography 2000s

Polyamine levels are greatly increased in alveolar macrophages (AMs) during Pneumocystis pneumonia (PCP), leading to increased production of H(2)O(2), which causes AMs to undergo apoptosis. One of the mechanisms by which polyamine levels in AMs are elevated is enhanced uptake of exogenous polyamines. In this study, the possibility of targeting polyamine uptake as a treatment for PCP was examined. Four anthracene- and one benzene-polyamine conjugates that are potential polyamine transport inhibitors, including N1-anthracen-9-ylmethylbutane-1,4-diamine; N-(4-aminobutyl)-N-anthracen-9-ylmethylbutane-1,4-diamine; N-[4-(4-aminobutylamino)butyl]-N-anthracen-9-ylmethylbutane-1,4- diamine; N-(4-amino-butyl)-N'-(10-{[4-(4-aminobutylamino)butylamino]-methyl}anthracen-9-ylmethyl)butane-1,4-diamine (44-Ant-44); and benzene-polyamine conjugate N-(4-amino-butyl)-N'-(4-{[4-(4-amino-butylamino)butylamino]-methyl} benzyl)butane-1,4-diamine (44Bn-44), were tested. Compounds 44-Ant-44 and 44-Bn-44 were found to have a very low toxicity to AMs …

Iron In Arterial Plaque: A Modifiable Risk Factor For Atherosclerosis, Jerome L. Sullivan Jan 2009

Iron In Arterial Plaque: A Modifiable Risk Factor For Atherosclerosis, Jerome L. Sullivan

Faculty Bibliography 2000s

It has been proposed that iron depletion protects against cardiovascular disease. There is increasing evidence that one mechanism for this protection may involve a reduction in iron levels within atherosclerotic plaque. Large increases in iron concentration are seen in human atherosclerotic lesions in comparison to levels in healthy arterial tissue. In animal models, depletion of lesion iron levels in vivo by phlebotomy, systemic iron chelation treatment or dietary iron restriction reduces lesion size and/or increases plaque stability. A number of factors associated with increased arterial disease or increased cardiovascular events is also associated with increased plaque iron. In rats, infusion …
