Gendered Images Of Expertise, Leadership And Virture, Robin Lynn Larson Jan 2012

Gendered Images Of Expertise, Leadership And Virture, Robin Lynn Larson

Electronic Theses and Dissertations 2010 - 2019

In this dissertation, a theoretical framework is developed from Camilla Stivers' (2002) argument that images of expertise, leadership and virtue are used to defend public administration's legitimacy in the face of criticisms about the inefficiencies of government and the power wielded by bureaucrats. Stivers argues that these legitimizing and traditional images have historical and cultural roots in ideas associated with masculinity, and that this harms women in the public sector. The realm of policing faced similar criticisms and defended its legitimacy by altering practices, the day-to-day actions of police practitioners. The purpose of this dissertation is to explore the possibility …

Governance And Earnings Management Surrounding Dividend Initiation, Deborah Drummond Smith Jan 2012

Governance And Earnings Management Surrounding Dividend Initiation, Deborah Drummond Smith

Electronic Theses and Dissertations 2010 - 2019

Essay I: Governance surrounding dividend initiation. According to the free cash flow hypothesis, managers prefer to invest surplus cash, even in value reducing projects, rather than release it to shareholders. Yet, previous studies of dividend payout conclude that managers pay more in dividends when they are entrenched, supporting the substitute model... The results indicate that initiating firms have stronger shareholder rights, in contrast with much of the prior research on continuous divident payout. Firms with lower entrenchment index are more likely to initiate dividends... Essay II: Earnings management surrounding dividend initiation. Prior research tests earnings management surrounding changes in dividend …

Habitat Selection Among Fishes And Shrimp In The Pelagic Sargassum Community, Chelsea Bennice Jan 2012

Habitat Selection Among Fishes And Shrimp In The Pelagic Sargassum Community, Chelsea Bennice

Electronic Theses and Dissertations 2010 - 2019

Pelagic Sargassum was used to determine the effects of habitat architecture for one species of shrimp (Leander tenuicornis) and two species of fish (Stephanolepis hispidus and Histrio histrio). Inter-thallus spacing (low, medium, and high) and depth (shallow versus deep) were manipulated independently to test whether the spatial components of habitat architecture. Two differing habitats (Sargassum versus seagrass species) were tested for the structural component of habitat architecture. There were no significant results for inter-thallus spacing experiments for L. tenuicornis and S. hispidus. H histrio selected habitats with medium inter-thallus spacing in two treatments. Large individual H. histrio contributed mostly to …

Hypoxia-Regulated Glial Cell-Specific Gene Therapy To Treat Retinal Neovascularization, Manas Ranjan Biswal Jan 2012

Hypoxia-Regulated Glial Cell-Specific Gene Therapy To Treat Retinal Neovascularization, Manas Ranjan Biswal

Electronic Theses and Dissertations 2010 - 2019

Diabetic retinopathy is an ischemic retinal neovascular disease causing vision loss among adults. The studies presented involve the design and testing of a gene therapy vector to inhibit retinal revascularization, similar to that found in diabetic retinopathy. Gene therapy has proven to be an effective method to introduce therapeutic proteins to treat retinal diseases. Targeting a specific cell type and expression of therapeutic proteins according to the tissue microenvironment should have an advantage over traditional gene therapy by avoiding unwanted transgene expression. Hypoxia plays a significant role in the pathophysiology of many retinal ischemic diseases. Retinal Mèuller cells provide structural …

Inflammatory Response In Stress And The Role Of Autophagy In Breast Cancer, Lillian C. Onwuha-Ekpete

Electronic Theses and Dissertations 2010 - 2019

We attempted to understand the molecular regulators that impact inflammation using a rat model of human sensation-seeking/risk-taking trait for drug and stress vulnerability, based on their exploratory behavior displaying high rates (HRs) or low rates of locomotor reactivity (LRs) to environmental stress. We found that HRs have a pro-inflammatory phenotype as indicated by increased protein expression of the inflammatory cytokine TNF-(Sa(B. Furthermore, we found that HRs have a lower gene expression of the glucocorticoid receptor and histone deacetylase 2 which are known to play an immunosuppressive role. Autophagy (macroautophagy) is a homeostatic process needed for cell maintenance, growth and proliferation …

Phosphorus Limitation In Reef Macroalgae Of South Florida, Courtney. Kehler Jan 2012

Phosphorus Limitation In Reef Macroalgae Of South Florida, Courtney. Kehler

Electronic Theses and Dissertations 2010 - 2019

Nitrogen (N) has traditionally been regarded as the primary limiting nutrient to algal growth in marine coastal waters, but recent studies suggest that phosphorus (P) can be limiting in carbonate-rich environments. To better understand the importance of P. alkaline phosphatase activity (APA) was measured in reef macroalgae in seven counties of south Florida ; several significant trends emerged : 1) APA decreased geographically from the highest values in Dada>Monroe>Palm Beach>St. Lucie>Broward>Martin>Lee counties 2) APA varied temporally with increasing nutrient-rich runoff in the wet season 3) APA varied due to taxonomic division Phaeophyta>Rhodophyta>Chlorophyta …

Product Placement Within Violent Media, Johanna D. Berger Jan 2012

Product Placement Within Violent Media, Johanna D. Berger

Electronic Theses and Dissertations 2010 - 2019

Despite extensive research into memory and violence, relatively little is known about the relationship between violent media and memory of advertised products. Research has yielded contradictory evidence ; some scholars have found a negative relationship, others a nonexistent one... This research investigated the role of emotion in the relationship between violent media and product placement memory. This study creates insight into inconclusive previous findings by providing evidence that violence influences product memory. Specifically, participants were significantly worse at remembering products placed within violent clips (e.g., free recall, cued recall, recognition. Participants' emotional responses to the violent clips also appeared to …

Race And Representation In Friday Night Lights, Keisha. Johnson Jan 2012

Race And Representation In Friday Night Lights, Keisha. Johnson

Electronic Theses and Dissertations 2010 - 2019

This thesis will highlight the significance and representation of race in the film and television show Friday Night Lights. The core claim of my thesis will show that representation of race was different in the film as compared to the television show due to their various settings, one historical (1980s) and the other contemporary (2000s). While both the film and the television show were produced in the 2000s, their use of two different historical periods allows for contrasting representations of race even they both draw from the book Friday Night Lights. The film's representation of race is reflective of its …

Public Speaking As The Last Battlefield, Shaundi C. Newbolt Jan 2012

Public Speaking As The Last Battlefield, Shaundi C. Newbolt

Electronic Theses and Dissertations 2010 - 2019

Communication scholars are in disagreement over the presence of online public speaking courses in higher education. Despite limited research on the Online Public Speaking model, it is quickly replacing the traditional public speaking model in American colleges and universities. This study used Burkean Cluster-Agon Analysis to uncover core concepts from four contemporary public speaking textbooks used in various classroom models (traditional, online and hybrid). Concepts were then compared with traditional core concepts of early speech communication to determine if technology has influenced contemporary core concepts. Results determined that contemporary core concepts from three of the four public speaking textbooks reflected …

Religious Violence In Frank Herbert's Dune Series, Kenton Taylor Howard Jan 2012

Religious Violence In Frank Herbert's Dune Series, Kenton Taylor Howard

Electronic Theses and Dissertations 2010 - 2019

This thesis examines the first two novels of Frank Herbert's Dune series, Dune and Dune Messiah, in order to consider these two novels from the framework of postcolonial theory and analyze how religious violence becomes a source of subjugation, military power, and colonialism within the works. The three chapters of this thesis chart the creation of a colonial project through epistemic violence, physical power, and cultural control enabled by religion. This thesis argues that, in the Dune novels, religious violence functions as a colonial project that closely resembles the goals of real-world colonial enterprises, and the failure to manage this …

Assessing Environmental Inequality In Portland, Oregon: An Exploration Of Local Environmental Justice Struggles, Jordan Douglas Folks Jan 2012

Assessing Environmental Inequality In Portland, Oregon: An Exploration Of Local Environmental Justice Struggles, Jordan Douglas Folks

Dissertations and Theses

This thesis explores patterns of environmental inequality in Portland, Oregon; both the existence of spatial environmental inequalities and the structural and local forces which contribute to them. Research on environmental inequality, or inequitable exposure to toxins, has shown that minority and low-income populations experience the bulk of the exposure to environmental hazards. Although Portland is often cited as the archetype of a sustainable city, environmental inequality is a pervasive issue. This thesis examines the health inequalities that characterize underserved communities in Portland. Utilizing a mixed methods approach, the researcher uses 1) logistic regression to statistically assess the relationship between race, …

Understanding The Emission From Semiconductor Nanoparticles, Beth Ann Manhat Jan 2012

Understanding The Emission From Semiconductor Nanoparticles, Beth Ann Manhat

Dissertations and Theses

This dissertation describes the synthesis and characterization of fluorescent semiconductor nanoparticles (NPs) in order to optimize their biomedical utility for imaging and sensing applications. While both direct and indirect bandgap semiconductor NPs have been studied, control over their emission properties vary. Quantum confinement (QC), which primarily controls the emission wavelength of nanosized semiconductors, dictates that as the size of semiconductor NPs decrease, the magnitude of the bandgap increases, resulting in changes in the observed emission wavelength: smaller NPs have a larger bandgap, and thus a bluer emission. However, surface, interfacial, or shell defects can act as non-radiative or radiative recombination …

Is Canada The New Shangri-La Of Global Securities Class Actions?, Tanya J. Monestier Jan 2012

Is Canada The New Shangri-La Of Global Securities Class Actions?, Tanya J. Monestier

Journal Articles

There has been significant academic buzz about Silver v. Imax, an Ontario case certifying a global class of shareholders alleging statutory and common law misrepresentation in connection with a secondary market distribution of shares. Although global class actions on a more limited scale have been certified in Canada prior to Imax, it can now be said that global classes have “officially” arrived in Canada. Many predict that the Imax decision means that Ontario will become the new center for the resolution of global securities disputes. This is particularly so after the United States largely relinquished this role in Morrison v. …

Statins In Unconventional Secretion Of Insulin-Degrading Enzyme And Degradation Of The Amyloid-Β Peptide, K Glebov, J Walter Jan 2012

Statins In Unconventional Secretion Of Insulin-Degrading Enzyme And Degradation Of The Amyloid-Β Peptide, K Glebov, J Walter

Peninsula Medical School

Population-based studies demonstrated that statins might decrease the risk of developing Alzheimer’s disease (AD). Statins inhibit the 3-hydroxy-3-methyl-glutaryl-coenzyme-A reductase and thereby de novo synthesis of cholesterol. Cell culture and animal studies indicated that cholesterol affects the proteolytic processing of the amyloid precursor protein and the generation of amyloid-β (Aβ). Recently, we have demonstrated that statins can also stimulate the degradation of Aβ. The statin-induced clearance of Aβ could be attributed to increased release of the insulin-degrading enzyme (IDE) via an exosome-related unconventional secretory pathway. Interestingly, this statin-induced secretion of exosome-associated IDE was independent of cellular cholesterol concentrations, but rather caused …

Social And Environmental Effects Of Shrimp Mariculture, Mary C. Crider Jan 2012

Social And Environmental Effects Of Shrimp Mariculture, Mary C. Crider

Electronic Theses and Dissertations 2010 - 2019

Shrimp mariculture expansion in developing countries has been criticized for its ecological destruction and the resulting social conflicts. In Ecuador, shrimp pond development particularly affects rural, coastal communities. This study addresses the environmental and social effects of shrimp farming in two Ecuadorian villages, Muisne and Bunche. Interview and survey responses indicate that locals have an overall negative view of the industry. In some instances, such as increased class marginalization through reduced access to subsistence collection areas, shrimp farming directly results in conflict. However, the data also demonstrates that ponds are only one of various stressors on mangrove ecosystems. Furthermore, mariculture …

The Role Of Insulin-Like Growth Factors Signaling In Merlin-Deficient Human Schwannomas., Sylwia Ammoun, M. Caroline Schmid, Natalia Ristic, Lu Zhou, David Hilton, Emanuela Ercolano, Camille Carroll, C. Oliver Hanemann Jan 2012

The Role Of Insulin-Like Growth Factors Signaling In Merlin-Deficient Human Schwannomas., Sylwia Ammoun, M. Caroline Schmid, Natalia Ristic, Lu Zhou, David Hilton, Emanuela Ercolano, Camille Carroll, C. Oliver Hanemann

Peninsula Medical School

Loss of the tumor suppressor merlin causes development of the tumors of the nervous system, such as schwannomas, meningiomas, and ependymomas occurring spontaneously or as part of a hereditary disease Neurofibromatosis Type 2 (NF2). Current therapies, (radio) surgery, are not always effective. Therefore, there is a need for drug treatments for these tumors. Schwannomas are the most frequent of merlin-deficient tumors and are hallmark for NF2. Using our in vitro human schwannoma model, we demonstrated that merlin-deficiency leads to increased proliferation, cell-matrix adhesion, and survival. Increased proliferation due to strong activation of extracellular-signal-regulated kinase 1/2 (ERK1/2) is caused by overexpression/activation …

Measuring The Performance Of Partnerships: Why, What, How, When?, C Kelly Jan 2012

Measuring The Performance Of Partnerships: Why, What, How, When?, C Kelly

School of Geography, Earth and Environmental Sciences

Partnerships have become increasingly prevalent across a wide range of sectors for the delivery of services and implementation of policy. Partnerships are seen as a more effective way of delivering policy interventions than state-led or ‘top-down’ approaches. Evaluating partnership performance is therefore crucial in order to determine whether partnerships really are better than more traditional methods of policy implementation. To date, however, partnership effectiveness has often been conceptualised as cumulative; the result of a set of variables acting in a one dimensional, linear way which results in the ability (or not) of a partnership to achieve its goals. This paper …

Moon Vehicle: Reflections From An Artist-Led Children's Workshop On The Chandrayaan-1 Spacecraft's Mission To The Moon, J Griffin Jan 2012

Moon Vehicle: Reflections From An Artist-Led Children's Workshop On The Chandrayaan-1 Spacecraft's Mission To The Moon, J Griffin

School of Art, Design and Architecture

This article reflects on the journey to the Moon of the spacecraft Chandrayaan-1 as it was interpreted through an artist-led workshop. The workshop participants were a group of children who lived close to where Chandrayaan was built and some of the engineers and scientists responsible for creating the spacecraft. Insights from the workshop show how a mission to the Moon draws on both the technological and the imaginative; they also have bearing on the relative agency of these individuals to contribute to the Moon missions in ways that are personally meaningful to them.
