Climate Change And Forest Diseases, R. N. Sturrock, S. J. Frankel, A. V. Brown, P. E. Hennon, J. T. Kliejunas, K. J. Lewis, J. J. Worrall, A. J. Woods Jan 2011

Climate Change And Forest Diseases, R. N. Sturrock, S. J. Frankel, A. V. Brown, P. E. Hennon, J. T. Kliejunas, K. J. Lewis, J. J. Worrall, A. J. Woods

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

As climate changes, the effects of forest diseases on forest ecosystems will change. We review knowledge of relationships between climate variables and several forest diseases, as well as current evidence of how climate, host and pathogen interactions are responding or might respond to climate change. Many forests can be managed to both adapt to climate change and minimize the undesirable effects of expected increases in tree mortality. We discuss four types of forest and disease management tactics – monitoring, forecasting, planning and mitigation – and provide case studies of yellow-cedar decline and sudden aspen decline to illustrate how forest diseases …

End-User Programmers And Their Communities: An Artifact-Based Analysis, Kathryn T. Stolee, Sebastian Elbaum, Anita Sarma Jan 2011

End-User Programmers And Their Communities: An Artifact-Based Analysis, Kathryn T. Stolee, Sebastian Elbaum, Anita Sarma

School of Computing: Conference and Workshop Papers

End-user programmers outnumber professionals programmers, write software that matters to an increasingly large number of users, and face software engineering challenges that are similar to their professionals counterparts. Yet, we know little about how these end-user programmers create and share artifacts as part of a community. To gain a better understanding of these issues, we perform an artifact-based community analysis of 32,000 mashups from the Yahoo! Pipes repository. We observed that, like with other online communities, there is great deal of attrition but authors that persevere tend to improve over time, creating pipes that are more configurable, diverse, complex, and …

Design And Synthesis Of Novel Agrofungicides Based On Naturally Occurring Pbdes, Robert Alexander Smith Jan 2011

Design And Synthesis Of Novel Agrofungicides Based On Naturally Occurring Pbdes, Robert Alexander Smith

Electronic Theses and Dissertations

Cyanobacterial symbionts of Indo Pacific marine sponges, e.g. Dysidea sp., produce hydroxylated (OH-) polybrominated diphenyl ethers (PDBEs) which likely function as chemical deterrents owing to their antifungal and antibacterial properties. Limiting the therapeutic potential and agricultural use of these antimicrobial natural products are the negative connotations associated with non hydroxylated anthropogenic PBDEs. Anthropogenic PBDEs are pervasive global pollutants used as flame retardant additives in many household goods, e.g. furniture, textiles, and electronics. These molecules have a propensity to bioaccumulate in living organisms, they easily traverse the trophic food chains, they are readily passed from mother to offspring, and many of …

A "Desperate Vitality": Tableaux Vivants In The Work Of Pasolini And Ontani (1963–1974), Anna Mecugni Jan 2011

A "Desperate Vitality": Tableaux Vivants In The Work Of Pasolini And Ontani (1963–1974), Anna Mecugni

Fine Arts Faculty Publications

This essay focuses on four key works by Pier Paolo Pasolini (1922-75) and Luigi Ontani (b. 1943) that involve tableaux vivants after sixteenth- and seventeenth-century paintings held in Italian churches and museums: Pasolini’s short film La ricotta (1963), and Ontani’s video Favola impropriata (1970-71) and two photographic works – La caduta dei ciechi d’après Brueghel and San Sebastiano nel bosco di Calvenzano (d’après Guido Reni) – also from circa 1970. In the 1960s and 1970s, several other Italian filmmakers and artists referenced past art in their work. Indeed, quotations and allusions to past art are characteristic of an idiosyncratic strain …

Those Wonderful People Across The Sea: Positive Out-Group Bias By Caucasians Toward Asians, Wing Sze Leung, Shue Ying Ting Jan 2011

Those Wonderful People Across The Sea: Positive Out-Group Bias By Caucasians Toward Asians, Wing Sze Leung, Shue Ying Ting

Papers from the International Association for Cross-Cultural Psychology Conferences

While individuals often favor their in-group, they sometimes favor an out-group, such as when Caucasians positively stereotype Asians' quantitative abilities. It is unclear, however, whether positive stereotypes of Asians extend into other domains and create a generalized halo effect that influences judgments on other attributes. To examine this, three studies were performed. In Study 1, Asians and Caucasians were equally biased toward an Asian's response to a calculus problem. In Study 2, Asians, but not Caucasians, gave lower grades to essay writers they guessed were Asian. In Study 3, Caucasians rated their ethnic group with fewer positive terms and more …

In Vitro And In Vivo Pharmacodynamic Characterization Of The Novel Plasma Kallikrein Inhibitor Pf-04886847, Dhaval Sanjeev Kolte Jan 2011

In Vitro And In Vivo Pharmacodynamic Characterization Of The Novel Plasma Kallikrein Inhibitor Pf-04886847, Dhaval Sanjeev Kolte

Electronic Theses and Dissertations

Plasma kallikrein plays an important role in the pathogenesis of inflammation and thrombosis. Kallikrein cleaves high molecular weight kininogen (HK) to liberate the potent pro-inflammatory peptide bradykinin (BK). BK upon activation of its constitutive B2 receptors on endothelial cells leads to an increase in intracellular Ca2+ level and subsequent production of nitric oxide (NO) and prostacyclin (PGI2), ultimately leading to vasodilation, hypotension, increased vascular permeability and vascular leakage. Further, kallikrein activates the complement system and stimulates neutrophil chemotaxis, aggregation and elastase release. Furthermore, kallikrein mediates the conversion of factor XII (FXII) to activated factor XII (FXIIa) thereby potentiating the intrinsic …

The Gay Of The Land: Queer Ecology And The Literature Of The 1960s, Jill Elizabeth Anderson Jan 2011

The Gay Of The Land: Queer Ecology And The Literature Of The 1960s, Jill Elizabeth Anderson

Electronic Theses and Dissertations

In this dissertation I argue not only that queer ecology is a legitimate and important next step for ecocritics and queer theorists but also that its literary application does a great amount of good in exploring and dismantling the natural/unnatural binary and exposing the ecological impact of the choices humans make everyday. I take as my method a combination of queer and environmental theory and literary criticism, as well as the foundational queer ecocritical works and include important historical and political perspectives influencing the emergence of the environmental and gay and lesbian movements. Through this dissertation, I legitimize more recent …

Food And Identity: A Case Study Of Roman Soldiers And Native Civilians In Roman Britain, Aaron Michael Bobik Jan 2011

Food And Identity: A Case Study Of Roman Soldiers And Native Civilians In Roman Britain, Aaron Michael Bobik

Electronic Theses and Dissertations

Food is a universal medium through which identity is expressed. In cultures both past and present, food represents a direct way to communicate many aspects of identity such as ethnicity, nationality, status, age, and gender. In archaeology, while the nutritional and economic roles of food have been a topic of study for decades, the relationship between food and identity is a research area largely in its infancy. In my thesis, I explore general aspects of identity in the past, and in particular, I utilize a case study of four archaeological sites (Segontium (Caernarfon), Portchester Castle, Wavendon Gate, and Dragonby) to …

Starved: Food Deserts In The Mississippi Delta, Novelette L. Brown Jan 2011

Starved: Food Deserts In The Mississippi Delta, Novelette L. Brown

Electronic Theses and Dissertations

This thesis examines the impact of food deserts on obesity, and builds a case for additional research on rural food deserts independent from urban ones. The Mississippi Delta consistently presents the highest obesity rates within the state, yet both the third unhealthiest county (Quitman) and the healthiest (DeSoto) are located in that region. One of the reasons there is such a large discrepancy between the health rankings of DeSoto and Quitman counties is that DeSoto is contained within the Greater Memphis Metropolitan Area, but Quitman is entirely rural. Previous research has focused on the prevalence of urban food deserts and …

A Field Validation Of Dam Indexing Methods In Mississippi, Steven Thomas Fox Jan 2011

A Field Validation Of Dam Indexing Methods In Mississippi, Steven Thomas Fox

Electronic Theses and Dissertations

Indexing methods are applied to dam inventories throughout the United States to assist in prioritizing resources to maintain aging dam structures. Three published indexing methods and one proposed method were applied to 24 dams through Mississippi. The majority of dams in Mississippi have little to no information concerning the performance records or design specifics of a given dam. Field assessments were conducted to determine the physical condition of each dam, identify potentially deficiencies at dams, and calculate a consequence in the event of a dam failure. The results of the four indexing methods will be compared and advantages and disadvantages …

The French Chef And The Cold War: Julia Child And The Mask Of Contained Domesticity, Hillary Ann Hamblen Jan 2011

The French Chef And The Cold War: Julia Child And The Mask Of Contained Domesticity, Hillary Ann Hamblen

Electronic Theses and Dissertations

Most scholarly studies and even general personal reflections about Julia Child portray her as a figure that changed the face of cooking, cookbooks, and cooking television for audiences of the late twentieth and twenty first centuries. While this is true, many of these studies and reflections do not acknowledge Child's ability to change mainstream ideas by conforming to some of them. While Child radicalized perceptions toward food and those who cook, she also represented a domestic woman and a wife. While Child's politics were indeed liberal, for the most part, her lifestyle was actually quite moderate. This project is an …

Pharmacokinetic Evaluation Of A Novel Compound, Sn79, A Putative Sigma-2 Receptor Antagonist, By Intravenous And Oral Administration In Rats, Harsha Vinnakota Jan 2011

Pharmacokinetic Evaluation Of A Novel Compound, Sn79, A Putative Sigma-2 Receptor Antagonist, By Intravenous And Oral Administration In Rats, Harsha Vinnakota

Electronic Theses and Dissertations

Considering the alarming rates at which substance drug abuse, especially cocaine, is increasing in today's society, there is a lot of impetus on the development of medications that can effectively help alleviate its toxicity and addiction. The affinity of cocaine to sigma receptors (sigma-1 and sigma-2) rendered the hypothesis that blocking sigma receptors could be a possible mechanism to attenuate cocaine-induced toxicity and addiction. In this view, SN79, a synthetic compound with selectivity to both sigma-1 and sigma-2 receptors garnered our attraction for its use as an antagonist. This dissertation encompasses detailed investigation of SN79 from drug discovery and development …

Reforming Tastes: Taste As A Print Aesthetic In American Cookery Writing, Sarah Wurgler Walden Jan 2011

Reforming Tastes: Taste As A Print Aesthetic In American Cookery Writing, Sarah Wurgler Walden

Electronic Theses and Dissertations

Many eighteenth-century philosophers such as Kant and Hume worked to develop discourses of taste as a means of standardizing cultural behaviors. Using physical taste as a metaphor for aesthetic perception and judgment, these writers could both define and abstract group boundaries. As American writers worked to distinguish their nation from their British forebears, many recognized the utility of taste-based discourse and worked to develop cultural tastes around shared principles of egalitarianism and democracy. Cookbooks and domestic writing soon engaged these discourses, as it was the task of women to cultivate a virtuous citizenry, and—through domestic print culture—to demonstrate the deleterious …

Integration Of Cognitive And Physical Factors To Model Human Performance In Fluid Power Systems, Khaliah K. Hughes Jan 2011

Integration Of Cognitive And Physical Factors To Model Human Performance In Fluid Power Systems, Khaliah K. Hughes

Dissertations

Fluid power technology is constantly evolving as a result of the interaction between the human and the system. Systems such as the hydraulic excavator utilize this technology in order to deliver safe, efficient, and effective performance. However, traditional research has placed much emphasis on technical performance rather than on human components. Imbalances of this nature demonstrate inadequate understanding, lack of knowledge, and limited research on the factors affecting performance. This research aims to address these shortcomings by using an integrated approach to better model human performance in fluid power systems. Through the development of an integrative framework considering cognitive and …

Heller's Gridlock Economy In Perspective: Why There Is Too Little, Not Too Much Private Property, Richard A. Epstein Jan 2011

Heller's Gridlock Economy In Perspective: Why There Is Too Little, Not Too Much Private Property, Richard A. Epstein

Faculty Articles

This Article critiques Michael Heller's important contribution in The Gridlock Economy. At no point does this Article take the position that gridlock, or the associated anticommons, is not a serious issue in the design of a legal system. But gridlock is not the major source of social dislocation; nor is private ownership the major source of gridlock. More concretely, this Article examines the other important sources of economic distortion that are unrelated to economic gridlock from private action. These include the use of excessive government subsidies (as with health care); misguided government licenses (as with broadcast licenses); the unwise use …

‘The Mystic Drum’: Critical Commentary On Gabriel Okara’S Love Lyrics, Chukwuma Azuonye Jan 2011

‘The Mystic Drum’: Critical Commentary On Gabriel Okara’S Love Lyrics, Chukwuma Azuonye

Africana Studies Faculty Publication Series

Structurally, Okara’s love lyric, “The Mystic Drum,” evinces a tripartite ritual pattern of initiation from innocence through intimacy to experience. By comparison to the way of Zen as manifested in the experience of Zen Master, Ch’ing Yuän Wei-hsin, this pattern resolves itself into an emotional and epistemological journey from conventional knowledge (born of innocence) through more intimate knowledge (born of closer apperception of reality) to substantial knowledge (born of experience). The substantial knowledge born of experience empowers the lover to understand that beneath the surface attractiveness of what we know very well (such as the women we love) may lie …

'The White Man Laughs': Commentary On The Satiric Dramatic Monologues Of Gabriel Okara, Chukwuma Azuonye Jan 2011

'The White Man Laughs': Commentary On The Satiric Dramatic Monologues Of Gabriel Okara, Chukwuma Azuonye

Africana Studies Faculty Publication Series

Examined in the present article are two early satiric lyrics of Gabriel Okara—“Once Upon a Time” and “He Laughed and Laughed and Laughed”—which are the products of the postcolonial cultural war environment in which the issues of modernity, alterity (otherness or difference) and afro-authenticity implicated in Achebe’s ripostes on the bigotry of the colonialist critic were central. The tone of this discourse amongst leading African intelligentsia was set in the 1930’s and 1940’s by four fellow south-eastern Nigerian writers in their semi-autobiographical blueprints for African cultural emancipation—Renascent Africa ((1937)) by Nnamdi Azikiwe (1904–1996); British and Axis Aims in Africa (1942) …

Use Of Mushroom Extract To Enhance Quality And Health Benefits Of Dairy Products, Osman A. Hassan Jan 2011

Use Of Mushroom Extract To Enhance Quality And Health Benefits Of Dairy Products, Osman A. Hassan

Dissertations

Bifidobacteria and Lactobacilli are purportedly beneficial to human health and are called probiotics which are live microorganisms, when administered in adequate amounts conferring a health benefit on the host. It is believed that the maximum probiotics effect can be achieved if the organisms adhere to intestinal mucosal cells. Probiotics, perhaps in combination with prebiotics, may become an important means of preventing and treating disease. In fact, several types of diarrhea have been successfully treated with probiotics. The mechanisms behind favorable clinical outcome are still largely unknown, however, the potential benefits of probiotic therapy promise to be almost limitless. Organic acids …

Use Of A Bacteriophage Cocktail In Combination With Modified Atmosphere Packaging To Control Escherichia Coli O157:H7 Contamination On Fresh-Cut Green Leafy Vegetables, Olcay Boyacioglu

Dissertations

The 2006 multi-state Escherichia coli O157:H7 (EHEC) outbreak linked to bagged spinach raised concerns about the safety of fresh produce. One novel approach to control foodborne pathogens is lytic bacteriophages, which does not affect the produce microflora. The objectives of this study were; 1) to test and verify the efficacy of a phage cocktail against EHEC in a laboratory medium, 2) to determine the effectiveness of the phage cocktail on fresh-cut leafy greens, and 3) to test and compare the effectiveness of the phage cocktail against EHEC on fresh-cut green leafy vegetables stored under air and modified air (low O2/high …

Quantification Of An Ultrasound Test Apparatus And Its Potential Use To Control Nuisance Species In Commercial Aquaculture Settings, Bradley T. Goodwiller Jan 2011

Quantification Of An Ultrasound Test Apparatus And Its Potential Use To Control Nuisance Species In Commercial Aquaculture Settings, Bradley T. Goodwiller

Electronic Theses and Dissertations

As one step in the investigation of using acoustics to improve aquaculture production, work was pursued on the possible use of ultrasound to control the Bolbophorus trematode in commercial catfish ponds. The trematode population can be controlled by eliminating the host ram's horn snail via exposure to high amplitude ultrasound. Initial laboratory tests indicated that a commercially available sonicator (operating at 20 kHz) is capable of killing individual snails in fish tanks. More thorough testing indicated efficiency rates of approximately 35% on batches of 10 snails. In addition to the snails killed immediately, there was evidence that the sonication technique …

Exploring Patterns Of Genetic Diversity Of A Malagasy Ant Species: Anochetus Madagascarensis, Nicole Annette Lewis Jan 2011

Exploring Patterns Of Genetic Diversity Of A Malagasy Ant Species: Anochetus Madagascarensis, Nicole Annette Lewis

Electronic Theses and Dissertations

Madagascar is extremely diverse and imperiled. Close to 90% of all land dwelling species are endemic to Madagascar (plants, reptiles, mammals and amphibians). Understanding patterns of genetic diversity for species can aid in better conservation efforts. In this study, I focus on the endemic Malagasy ant species, Anochetus madagascarensis. By employing a broad geographic sample of this species from throughout its distribution and a multilocus genetic data set, I explored population structure and historical factors that affected these patterns. I tested hypotheses proposed to be responsible for generating population structure, and by extension the process of speciation in Madagascar, including …

The Present Past - A Middle Swabian Dialect In The 21st Century, Stefanie Hirscher Jan 2011

The Present Past - A Middle Swabian Dialect In The 21st Century, Stefanie Hirscher

Electronic Theses and Dissertations

Dialects throughout the Federal Republic of Germany not only vary greatly among themselves, but also tend to show internal variations with regard to dialect speaker groups, due to the influence of Standard German along with other regional factors. Medium-sized towns seem to be at the center of this dialect-standard continuum, as speakers from both rural and more urban areas come together in these towns. This study sought to investigate the state of the Middle Swabian dialect as spoken in Schwäbisch Gmünd, a medium-sized town in Southwestern Germany. Previous studies of this dialect have focused on rural areas and found only …

Expression And Characterization Of The Bacterial Mechanosensitive Channel Mscs In Xenopus Laevis Oocytes., Elizabeth S. Haswell, Grigory Maksaev Jan 2011

Expression And Characterization Of The Bacterial Mechanosensitive Channel Mscs In Xenopus Laevis Oocytes., Elizabeth S. Haswell, Grigory Maksaev

Biology Faculty Research

We have successfully expressed and characterized mechanosensitive channel of small conductance (MscS) from Escherichia coli in oocytes of the African clawed frog, Xenopus laevis. MscS expressed in oocytes has the same single-channel conductance and voltage dependence as the channel in its native environment. Two hallmarks of MscS activity, the presence of conducting substates at high potentials and reversible adaptation to a sustained stimulus, are also exhibited by oocyte-expressed MscS. In addition to its ease of use, the oocyte system allows the user to work with relatively large patches, which could be an advantage for the visualization of membrane deformation. …
