Improved Peak Capacity For Ce Separations Of Enzyme Inhibitors With Activity-Based Detection Using Magnetic Bead Microreactors, Xiaoyan Yan, S. Douglass Gilman Jan 2010

Improved Peak Capacity For Ce Separations Of Enzyme Inhibitors With Activity-Based Detection Using Magnetic Bead Microreactors, Xiaoyan Yan, S. Douglass Gilman

Faculty Publications

A technique for separating and detecting enzyme inhibitors was developed using CE with an enzyme microreactor. The on-column enzyme microreactor was constructed using NdFeB magnet(s) to immobilize alkaline phosphatase-coated superparamagnetic beads (2.8 mm diameter) inside a capillary before the detection window. Enzyme inhibition assays were performed by injecting a plug of inhibitor into a capillary filled with the substrate, AttoPhos. Product generated in the enzyme microreactor was detected by LIF. Inhibitor zones electrophoresed through the capillary, passed through the enzyme microreactor, and were observed as negative peaks due to decreased product formation. The goal of this study was to improve …

The Torture Lawyers, Michael P. Scharf Jan 2010

The Torture Lawyers, Michael P. Scharf

Faculty Publications

This article recounts the story about how these four individuals intentionally cut off the government's primary experts on the Geneva Conventions, the Torture Convention, and customary international law from the decision making process. In doing so, they presented a one-sided and distorted view of U.S. obligations under international law that led to a widespread government policy and practice of torture. It also reveals how a trio of important Supreme Court precedents disrupted these plans, and ultimately swung the balance back in favor of compliance with international law.

Renegotiating Barbuda's Commons: Recent Changes In Barbudan Open-Range Cattle Herding, Andrew Sluyter, Amy E. Potter Jan 2010

Renegotiating Barbuda's Commons: Recent Changes In Barbudan Open-Range Cattle Herding, Andrew Sluyter, Amy E. Potter

Faculty Publications

Barbuda remains little developed and sparsely populated relative to its neighbors in the Leeward Lesser Antilles, a rather extraordinary and relatively unknown Caribbean place. Much of its distinctiveness derives from the communal land-tenure system, itself rooted in three centuries of open-range cattle herding. Yet, as revealed through interviews, newspaper archives, and landscape observations, openrange cattle herding has declined over the past three decades, with related changes in land tenure. As the new Barbuda Land Act came into effect in 2008, codifying the communal tenure system, the very landscape elements that manifest open-range herding have become obscure. In particular, the rock-walled …

The Hispanic Atlantic's Tasajo Trail, Andrew Sluyter Jan 2010

The Hispanic Atlantic's Tasajo Trail, Andrew Sluyter

Faculty Publications

Produced along the Río de la Plata during the nineteenth century, shipped to Havana, and consumed by African slaves, the salt-cured beef known as tasajo affected both of those places and, to some degree, the Atlantic world in general. Initial exploration of the tasajo trail that connected Buenos Aires and Cuba employs primary sources such as nineteenth-century descriptions and shipping records to characterize the landscapes, places, routes, and agents of the largely unexplored research territory of that anomalous commodity: one that, unlike others such as sugar, slaves not only produced but also consumed; one that underpinned more prominent, latitudinal transatlantic …

Brucella Species Survey In Polar Bears (Ursus Maritimus) Of Northern Alaska, Todd M. O'Hara, Darce Holcomb, Philip Elzer, Jessica Estepp, Quinesha Perry, Sue Hagius, Cassandra Kirk Jan 2010

Brucella Species Survey In Polar Bears (Ursus Maritimus) Of Northern Alaska, Todd M. O'Hara, Darce Holcomb, Philip Elzer, Jessica Estepp, Quinesha Perry, Sue Hagius, Cassandra Kirk

Faculty Publications

We report on the presence of specific antibodies to Brucella spp. and Yersinia enterocolitica in polar bears (Ursus maritimus) from northern Alaska (southern Beaufort Sea) during 2003-2006. Based on numerous known stressors (e.g., climate change and loss of sea ice habitat, contaminants), there is increased concern regarding the status of polar bears. Considering these changes, it is important to assess exposure to potentially pathogenic organisms and to improve understanding of transmission pathways. Brucella or specific antibodies to Brucella spp. has been reported in marine mammals. Various assays were used to elucidate the pathway or source of exposure (e.g., "marine" vs. …

Testing Protozoacidal Activity Of Ligand-Lytic Peptides Against Termite Gut Protozoa In Vitro (Protozoa Culture) And In Vivo (Microinjection Into Termite Hindgut), Claudia Husseneder, Amit Sethi, Lane Foil, Jennifer Delatte Jan 2010

Testing Protozoacidal Activity Of Ligand-Lytic Peptides Against Termite Gut Protozoa In Vitro (Protozoa Culture) And In Vivo (Microinjection Into Termite Hindgut), Claudia Husseneder, Amit Sethi, Lane Foil, Jennifer Delatte

Faculty Publications

We are developing a novel approach to subterranean termite control that would lead to reduced reliance on the use of chemical pesticides. Subterranean termites are dependent on protozoa in the hindguts of workers to efficiently digest wood. Lytic peptides have been shown to kill a variety of protozoan parasites (Mutwiri et al. 2000) and also protozoa in the gut of the Formosan subterranean termite, Coptotermes formosanus (Husseneder and Collier 2009). Lytic peptides are part of the nonspecific immune system of eukaryotes, and destroy the membranes of microorganisms (Leuschner and Hansel 2004). Most lytic peptides are not likely to harm higher …

A Phylogenetic Approach To Disentangling The Role Of Competition And Habitat Filtering In Community Assembly Of Neotropical Forest Birds, Juan Pablo Gómez, Gustavo A. Bravo, Robb T. Brumfield, José G. Tello, Carlos Daniel Cadena Jan 2010

A Phylogenetic Approach To Disentangling The Role Of Competition And Habitat Filtering In Community Assembly Of Neotropical Forest Birds, Juan Pablo Gómez, Gustavo A. Bravo, Robb T. Brumfield, José G. Tello, Carlos Daniel Cadena

Faculty Publications

Methods that assess patterns of phylogenetic relatedness, as well as character distribution and evolution, allow one to infer the ecological processes involved in community assembly. Assuming niche conservatism, assemblages should shift from phylogenetic clustering to evenness with decreasing geographic scale because the relative importance of mechanisms that shape assemblages is hypothesized to be scale-dependent. Whereas habitat filtering is more likely to act at regional scales because of increased habitat heterogeneity that allows sorting of ecologically similar species in contrasting environments, competition is more likely to act at local scales because low habitat heterogeneity provides few opportunities for niche partitioning. We …

Comparison Of Structure-Based And Threading-Based Approaches To Protein Functional Annotation, Michal Brylinski, Jeffrey Skolnick Jan 2010

Comparison Of Structure-Based And Threading-Based Approaches To Protein Functional Annotation, Michal Brylinski, Jeffrey Skolnick

Faculty Publications

To exploit the vast amount of sequence information provided by the Genomic revolution, the biological function of these sequences must be identified. As a practical matter, this is often accomplished by functional inference. Purely sequencebased approaches, particularly in the "twilight zone" of low sequence similarity levels, are complicated by many factors. For proteins, structure-based techniques aim to overcome these problems; however, most require high-quality crystal structures and suffer from complex and equivocal relations between protein fold and function. In this study, in extensive benchmarking, we consider a number of aspects of structure-based functional annotation: binding pocket detection, molecular function assignment …

The Impacts Of Land Use And Development Patterns On Water Quality Of The Belgrade Lakes, Ian M. Mccullough Jan 2010

The Impacts Of Land Use And Development Patterns On Water Quality Of The Belgrade Lakes, Ian M. Mccullough

Honors Theses

The purpose of this study was to assess the impacts of patterns of land use and development on water quality in the Belgrade Lakes on a regional scale. Regional research and cooperation could identify key areas in the watershed where development or changing land use could have the greatest negative influences on lake water quality. Past work has centered on water chemistry, nutrient dynamics, development and economic factors but there has been no comprehensive analysis of land use and development history for the entire Belgrade Lakes Region. The Belgrade Lakes are a chain of 7 lakes in central Maine connected …

Employee Free Choice Or Employee Forged Choice? Race In The Mirror Of Exclusionary Hierarchy, Harry G. Hutchinson Jan 2010

Employee Free Choice Or Employee Forged Choice? Race In The Mirror Of Exclusionary Hierarchy, Harry G. Hutchinson

Michigan Journal of Race and Law

The Employee Free Choice Act (EFCA) is arguably the most transformative piece of labor legislation to come before Congress since the enactment of the National Labor Relations Act of 1935 (NLRA). One of the newest attempts to transform labor relations is the EFCA. The first to disappear under the EFCA would be a system of union democracy whereby unions could only obtain the rights of exclusive representation for firms if they could prevail in a secret-ballot election. Second, the EFCA would eliminate tile necessity of a freely negotiated collective bargaining agreement between management and labor and instead substitute compulsory arbitration. …

Marketing Mothers' Milk: The Commodification Of Breastfeeding And The New Markets For Breast Milk And Infant Formula, Linda C. Fentiman Jan 2010

Marketing Mothers' Milk: The Commodification Of Breastfeeding And The New Markets For Breast Milk And Infant Formula, Linda C. Fentiman

Nevada Law Journal

Today, breastfeeding, human breast milk, and its substitute, infant formula, are commodities. "Mothers' milk" is marketed both literally and figuratively, as a good for sale, a normative behavior, and a cure for much of what ails twenty-first century America. Like previous exploitations of women's bodies, including their eggs and uteruses, the idea that human milk is a valuable good that can be given away, traded in a market, or subjected to scientific experimentation raises fundamental moral and legal questions. This Article examines the marketing of breastfeeding, the emerging markets in human milk, and the growing market in infant formula through …

Mindfulness, Emotions, And Mental Models: Theory That Leads To More Effective Dispute Resolution, Peter Reilly Jan 2010

Mindfulness, Emotions, And Mental Models: Theory That Leads To More Effective Dispute Resolution, Peter Reilly

Nevada Law Journal

This Article suggests that law students and lawyers can be introduced to, and even begin to master, some of the same transformational principles, skill sets, and behaviors that poured forth from FDR as a result of his intense physical and personal challenges. At the core of nearly all great negotiators, mediators, lawyers, and leaders is a person who has learned to connect with other people, that is, to build relationships of trust, cooperation, and collaboration. Additionally, this Article argues that where people first learn a sense of self and others through both theoretical and practical knowledge and understanding of mindfulness …

Mindfulness, Emotions, And Ethics: The Right Stuff?, Ellen Waldman Jan 2010

Mindfulness, Emotions, And Ethics: The Right Stuff?, Ellen Waldman

Nevada Law Journal

This essay celebrates Leonard Riskin's call to arms while suggesting some limits to what mindfulness can achieve in the ethical realm. I discuss recent developments in neuroethics that imply a prominent role for emotions in establishing ethical restraint. The Article also surveys a growing body of evidence that suggests the directive power of our emotions remains largely hidden from and impervious to the control of our “reasoning” selves. Lastly, the author examines what Riskin has, in an earlier work, described as the ethical hard case in light of recent explorations into the emotional wellsprings of deontological versus consequentialist thinking. Although …

Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor Jan 2010

Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor

Honors Theses

Environmentalism in the United States manifests itself in numerous ways. While American environmentalists have been grouped into broad camps over the years, observers have struggled to accurately classify the different components of the movement. Lately, environmentalists have been characterized based on their chosen modus operandi. Environmentalists who employ typical interest group tactics of policy advocacy and accept the notion of political compromise can generally be called 'mainstream.' Alternatively, those environmentalists who employ non-conventional strategies like direct action and take a no-compromise stance on environmental issues are typically described as 'radical.' Despite these distinctions, both radical and mainstream environmentalists are parts …

Assessing Genetic Differentiation Among Populations Of The Invasive Plant Impatiens Glandulifera In Maine, Jordan R. Schoonover Jan 2010

Assessing Genetic Differentiation Among Populations Of The Invasive Plant Impatiens Glandulifera In Maine, Jordan R. Schoonover

Honors Theses

The annual herbaceous plant Impatiens glandulifera Royle is native to the Himalayas and is a significant invasive species in Europe. In the past century, it was introduced to the United States, where it has become established in 12 states. This study evaluated genetic differentiation among four Maine populations, to address a theory that posits hybridization of distinct lineages as a trigger for invasiveness. Regions of microsatellite repeats were evaluated at two polymorphic loci for 41 plants sampled from the four populations. A striking finding was that the observed heterozygosity was substantially higher than the heterozygosity expected from random combination of …

Migration, Food And Cultural Production Across Changing Afro-Ecuadorian Geographies, Amelia J. Swinton Jan 2010

Migration, Food And Cultural Production Across Changing Afro-Ecuadorian Geographies, Amelia J. Swinton

Honors Theses

The human geography of Ecuador is changing. Urban Afro-Ecuadorians now outnumber those living in the two rural regions that have been the ancestral homelands of the population. This physical transformation assaults Ecuador's historically racialized geography, which conflated cities, modernity and white-mestizo identity. Though Afro-Ecuadorians living in the rural north had previously been physically and figuratively located outside of the national project, Ecuador’s new constitution has sought to reverse this institutionalized exclusion. National belonging has been reframed through the concept of interculturality, which recognizes diversity and equality at the same time. I conducted two periods of fieldwork in the north-central Chota …

On Perfect Friendship: An Outline And A Guide To Aristotle's Philosophy Of Friendship, Kristen Psaty Jan 2010

On Perfect Friendship: An Outline And A Guide To Aristotle's Philosophy Of Friendship, Kristen Psaty

Honors Theses

Providing insight into such timeless questions as: What is friendship? Are the best friends similar or dissimilar? and Does having friends make you a better person?, the paper addresses the importance of friendship for Aristotle, but also for the modern reader as well. A topic of special philosophical concern, Aristotle (384-322 B.C.) considered friendship to be necessary in achieving a virtuous and fulfilling life. Consequently, he wrote more about friendship than any other virtue he presented. This paper lays the foundation for understanding Aristotle’s philosophy of friendship as well as its position within his larger moral schema. The image of …

The Wheat Bzip Factor, Taabf1, Mediates Aba-Induced Gene Expression In Bombarded Barley Aleurone Layers, Benjamin R. Keyser Jan 2010

The Wheat Bzip Factor, Taabf1, Mediates Aba-Induced Gene Expression In Bombarded Barley Aleurone Layers, Benjamin R. Keyser

Honors Theses

The plant hormone Abscisic acid (ABA) plays a central role in maturation and germination in seeds, as well as mediating adaptive responses to abiotic environmental stresses. ABA induces the expression of many genes, including late-embryogenesis-abundant genes such as HVA1. To elucidate the ABA signaling pathway leading to HVA1 expression, we focus on the bZIP factor TaABF1. Analysis of the interplay between ABA and TaABF1 in the aleurone cells of imbibing cereal grains indicated that the two are not additive in their induction of the HVA1 promoter. A synthetic ABA analog, PBI-51, did not specifically inhibit the effect of exogenous ABA …

The Differential Roles Of D-Pax2 Variants In Regulating Drosophila Eye And Bristle Development, Colin J. O’Shea Jan 2010

The Differential Roles Of D-Pax2 Variants In Regulating Drosophila Eye And Bristle Development, Colin J. O’Shea

Honors Theses

The ability to appropriately interact with the environment is crucial to an organism’s survival. The establishment of functional sensory systems, such as the bristles and eyes in Drosophila, is a critical event during the development of the organism. The transcription factor D Pax2 is involved in the differentiation of the shaft and glial cells in the developing bristle (Kavaler et al., Dev, 126:2261-2272, 1999) and of the cone and primary pigment cells in the developing eye (Fu and Noll, Genes Dev, 11:389-405, 1997). How D-Pax2 contributes to distinct differentiative pathways in different cell types is not known. Recent work by …

The Role Of Taabf1 In Abscisic Acid-Mediated Suppression Of 𝒶-Amylase Gene Expression In Cereal Grains, Lauren J. Harris Jan 2010

The Role Of Taabf1 In Abscisic Acid-Mediated Suppression Of 𝒶-Amylase Gene Expression In Cereal Grains, Lauren J. Harris

Honors Theses

The phytohormones gibberellin (GA) and abscisic acid (ABA) regulate important developments events in germinating seeds. Specifically, GA induces the expression of hyrolase genes, like the α-amylase gene Amy32b, which mobilizes starch reserves to be used by the embryo, and ABA suppresses this induction. Recent advancements identified ABA and GA receptors and key components in the signaling pathways, however, the mechanism of crosstalk between the hormones remains largely unknown. To further elucidate the mechanism of ABA suppression of GA-induced genes, we focused on the transcription factor TaABF1, a member of the ABA response element binding factor family. TaABF1 has been shown …
