Using Physiology To Predict The Responses Of Ants To Climatic Warming, Sarah E. Diamond, Clint A. Penick, Shannon L. Pelini, Aaron M. Ellison, Nicholas J. Gotelli, Nathan J. Sanders, Robert R. Dunn Dec 2013

Using Physiology To Predict The Responses Of Ants To Climatic Warming, Sarah E. Diamond, Clint A. Penick, Shannon L. Pelini, Aaron M. Ellison, Nicholas J. Gotelli, Nathan J. Sanders, Robert R. Dunn

College of Arts and Sciences Faculty Publications

Physiological intolerance of high temperatures places limits on organismal responses to the temperature increases associated with global climatic change. Because ants are geographically widespread, ecologically diverse, and thermophilic, they are an ideal system for exploring the extent to which physiological tolerance can predict responses to environmental change. Here, we expand on simple models that use thermal tolerance to predict the responses of ants to climatic warming. We investigated the degree to which changes in the abundance of ants under warming reflect reductions in the thermal niche space for their foraging. In an eastern deciduous forest system in the United States …

College of Agriculture and Life Sciences Faculty Publications

Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in …


Coupling Self-Organizing Maps With A Naïve Bayesian Classifier: Stream Classification Studies Using Multiple Assessment Data, Nikolaos Fytilis, Donna M. Rizzo Nov 2013

Coupling Self-Organizing Maps With A Naïve Bayesian Classifier: Stream Classification Studies Using Multiple Assessment Data, Nikolaos Fytilis, Donna M. Rizzo

College of Engineering and Mathematical Sciences Faculty Publications

Organizing or clustering data into natural groups is one of the most fundamental aspects of understanding and mining information. The recent explosion in sensor networks and data storage associated with hydrological monitoring has created a huge potential for automating data analysis and classification of large, high-dimensional data sets. In this work, we develop a new classification tool that couples a Naïve Bayesian classifier with a neural network clustering algorithm (i.e., Kohonen Self-Organizing Map (SOM)). The combined Bayesian-SOM algorithm reduces classification error by leveraging the Bayesian's ability to accommodate parameter uncertainty with the SOM's ability to reduce high-dimensional data to lower …


Strategic Planning For The Vermont Apple Industry: Planning For Success In The 21st Century, Terence L. Bradshaw Nov 2013

Strategic Planning For The Vermont Apple Industry: Planning For Success In The 21st Century, Terence L. Bradshaw

College of Agriculture and Life Sciences Faculty Publications

For over a century, large-scale agriculture in Vermont has been identified with three primary crops: milk, maple, and apples. Today, apples are grown on about 3200 acres in Vermont, and contribute $20 million annually to the state’s agricultural economy. Through the 1980s, Vermont apples were sold largely to wholesale, out-of-state markets, and were packed and shipped by in-state and out-of-state firms. By the 1990s, changes in world and national markets signaled a downturn in the Vermont apple industry, and by the end of the decade, many operations had closed or were facing significant difficulties. In 1998, the Vermont Tree Fruit …


Why Some Students Continue To Value Individual, Face-To-Face Research Consultations In A Technology-Rich World, Trina J. Magi, Patricia E. Mardeusz Nov 2013

Why Some Students Continue To Value Individual, Face-To-Face Research Consultations In A Technology-Rich World, Trina J. Magi, Patricia E. Mardeusz

University Libraries Faculty and Staff Publications

For decades, academic librarians have provided individual research consultations for students. There is little information, however, about why students schedule consultations, the kinds of assistance students feel are provided by librarians during consultations, and what students find valuable about face-to-face consultations, even with the availability of online research help. This exploratory, qualitative study of individual research consultations at the University of Vermont gathered students’ views on these questions. The findings will help librarians better understand how individual consultations serve students and what role consultations should play in the mix of reference services offered.

Evaluation Of National Park Service 21st Century Relevancy Initiatives: Case Studies Addressing Racial And Ethnic Diversity In The National Park Service, Rebecca Stanfield Mccown Sep 2013

Evaluation Of National Park Service 21st Century Relevancy Initiatives: Case Studies Addressing Racial And Ethnic Diversity In The National Park Service, Rebecca Stanfield Mccown

Graduate College Dissertations and Theses

A long standing program of research has found consistent and substantial evidence of the underrepresentation of people of color in national parks and has identified potential reasons for this underrepresentation and barriers to participation. However, little research has examined cases where the National Park Service (NPS) has begun to successfully address diversity issues and engage diverse audiences. Through exploration of programs that successfully engage diverse youth, this study identifies promising practices that can be incorporated into NPS diversity programs across the national park system. The study was conducted in two phases. Phase one examined the current state of knowledge and …


The Role Of Ciliary Neurotrophic Factor And Trkb Signaling In Neuroblastoma, John Dewitt Sep 2013

The Role Of Ciliary Neurotrophic Factor And Trkb Signaling In Neuroblastoma, John Dewitt

Graduate College Dissertations and Theses

Neuroblastoma is the most common pediatric cancer in infants, arising from the sympathoadrenal lineage of the neural crest. Despite recent advances in other pediatric cancers, long term survival in high risk cases of neuroblastoma remains below 40%. Therefore, to develop successful therapeutics targeting high risk tumors, further research into the mechanisms involved in high risk tumor formation is necessary. Prognosis in neuroblastoma is determined by a number of factors, including certain genetic and biological variables. The genetic variable correlated most with high risk disease is amplification of the MYCN gene, which is present in ~25% of tumors. Additionally, ~70% of …


Identification Of The Regions In Factor V Mediating Its Edocytosis By Megakaryocytes To Form The Unique Platelet-Derived Cofactor Molecule, Sarah Abdalla Sep 2013

Identification Of The Regions In Factor V Mediating Its Edocytosis By Megakaryocytes To Form The Unique Platelet-Derived Cofactor Molecule, Sarah Abdalla

Graduate College Dissertations and Theses

Factor Va is a plasma protein that plays an important role in the regulation of blood coagulation by serving as the essential cofactor in thrombin generation via the prothrombinase complex. The procofactor, factor V, exists in two whole blood pools with 75-80% found in plasma, and 20-25% stored in the α-granules of platelets. As compared to the plasma procofactor, platelet-derived factor V is physically and functionally distinct, and displays a more procoagulant phenotype. Despite these profound differences, platelet-derived factor V originates via endocytosis of the plasma-derived procofactor by megakaryocytes. Endocytosis is mediated by two receptors: an unidentified, specific factor V …


Naughty In The Aughties, 21st Century British Adolescent Culture And Alienation In Skins Seasons 1-2, Megan Griffith Sep 2013

Naughty In The Aughties, 21st Century British Adolescent Culture And Alienation In Skins Seasons 1-2, Megan Griffith

Graduate College Dissertations and Theses

This thesis explores representations of British youth culture and adolescent identity formation in the ‘first generation’ (seasons 1-2) of the British television teen drama Skins (2007-8). Like its peers in the Teen TV genre, Skins focuses on normative teenage angst and rebellion that results in ‘naughty behavior’: sex, drug and alcohol use, and conflict with and alienation from parents. Skins sets itself apart from genre standards by heightening and glamorizing the way these behaviors are visually depicted. Furthermore, the characters experience very few substantial consequences or repercussions from parents or other authority figures, but rather repercussions come from within their …


Synthetic Feedback Loop For Increasing Microbial Biofuel Production Using A Biosensor, Mary Harrison Sep 2013

Synthetic Feedback Loop For Increasing Microbial Biofuel Production Using A Biosensor, Mary Harrison

Graduate College Dissertations and Theses

Current biofuel production methods use engineered bacteria to break down cellulose and convert it to biofuel. However, this production is limited by the toxicity of the biofuel to the organism that is producing it. Therefore, to increase yields, microbial biofuel tolerance must be increased. Tolerant strains of bacteria use a wide range of mechanisms to counteract the detrimental effects of toxic solvents. Previous research demonstrates that efflux pumps are effective at increasing tolerance to various biofuels. However, when overexpressed, efflux pumps burden cells, which hinders growth and slows biofuel production. Therefore, the toxicity of the biofuel must be balanced with …


Effects Of Methylmercury On Notch Targets And Motor Nerve Development In Drosophila, Gregory Engel Sep 2013

Effects Of Methylmercury On Notch Targets And Motor Nerve Development In Drosophila, Gregory Engel

Graduate College Dissertations and Theses

Methylmercury (MeHg) is a ubiquitous environmental toxin. Exposure to MeHg in humans occurs primarily through the consumption of contaminated seafood. MeHg has been shown to act most strongly during neural development. Epidemiological data on the effect MeHg exposure through seafood has on children and fetuses is conflicted, with large cohort studies showing both presence and absence of MeHg-induced deficits in achieving developmental milestones. Because of this uncertainty in the literature it is important that we come to understand the mechanisms of MeHg toxicity so that we might advise the public more accurately on the risks of MeHg exposure. Research into …


Analysis Of Stochastic Methods For Predicting Particle Dispersion In Turbulent Flows, Kyle Sala Sep 2013

Analysis Of Stochastic Methods For Predicting Particle Dispersion In Turbulent Flows, Kyle Sala

Graduate College Dissertations and Theses

The current research seeks to develop a computational model that accurately describes particle dispersion in turbulent ow. Current particle dispersion models do not accurately predict the small-scale clumping of particles in turbulent ow that occurs due to interaction with turbulent eddies. A new stochastic vortex structure (SVS) model was developed and compared with current stochastic Lagrangian models (SLM) for turbulent ows. To examine what characteristics of the uid ow eld that lead to dispersion of particles, a number of non trivial measures were used. A discrete-element model is used to transport particle locations for cases with and without adhesive forces. …


Growing Up With Vertigo: British Writers, Dc, And The Maturation Of American Comic Books, Derek Salisbury Sep 2013

Growing Up With Vertigo: British Writers, Dc, And The Maturation Of American Comic Books, Derek Salisbury

Graduate College Dissertations and Theses

At just under thirty years the serious academic study of American comic books is relatively young. Over the course of three decades most historians familiar with the medium have recognized that American comics, since becoming a mass-cultural product in 1939, have matured beyond their humble beginnings as a monthly publication for children. However, historians are not yet in agreement as to when the medium became mature. This thesis proposes that the medium’s maturity was cemented between 1985 and 2000, a much later point in time than existing texts postulate. The project involves the analysis of how an American mass medium, …


Behavioral Ecology And Genetics Of Potential Natural Enemies Of Hemlock Woolly Adelgid, Arielle Arsenault Sep 2013

Behavioral Ecology And Genetics Of Potential Natural Enemies Of Hemlock Woolly Adelgid, Arielle Arsenault

Graduate College Dissertations and Theses

Eastern and Carolina hemlock in the eastern United States are experiencing high mortality due to the invasive non-native hemlock woolly adelgid (HWA). The most promising means of control of HWA is the importation of natural enemies from the native range of HWA for classical biological control. Prior to release, natural enemies must be tested for suitability as a control agent, including the ability to locate the target prey. Coleopteran predators, including Scymnus coniferarum and Laricobius osakensis are under consideration as a means of biological control of HWA. Laricobius nigrinus was released in hemlock forests in 2003. It was recently discovered …


Development And Characterization Of Microfabricated Device For Real-Time Measurement Of The Size And Number Of Airborne Ultrafine Particles, Terence Barrett Sep 2013

Development And Characterization Of Microfabricated Device For Real-Time Measurement Of The Size And Number Of Airborne Ultrafine Particles, Terence Barrett

Graduate College Dissertations and Theses

Ultrafine particle emissions in motor-vehicle exhaust are associated with cardiopulmonary health impacts and increased mortality. The emission, evolution, and exposure-uptake of these particles, one hundred nanometers and smaller in diameter, are fundamentally quantified by the number concentration as a function of particle size. Ultrafine particle number distributions are widely varying and fast changing as they are strongly influenced by local environmental conditions and variation in vehicle operation and maintenance. Research and regulation to quantify and control such emissions rely on measurement of the number distribution of ultrafine particles in vehicle exhaust and by the roadside. Instruments to make such measurements …


Learning Starts With Design: Higher Education Faculty Explore The Use Of Universal Design For Learning (Udl) To Address The Needs Of All Students, Holly Buckland Parker Sep 2013

Learning Starts With Design: Higher Education Faculty Explore The Use Of Universal Design For Learning (Udl) To Address The Needs Of All Students, Holly Buckland Parker

Graduate College Dissertations and Theses

Today‘s college students, who are often referred to as ―Millennials‖, are entering college with different expectations for learning than students born before 1982 (Howe & Strauss, 2000). They expect to be able to access information instantly with their smart phones or laptop computers. At the same time, increasing numbers of students entering higher education have a disability of some kind. Some of these are observable disabilities that require specific accommodations to learning materials and the learning environment, such as ramps for students using wheelchairs and interpreters for students with hearing impairment. Students with learning disabilities represent a kind of ―invisible‖ …


The Spirituality Of Conciousness: From Mindfulness To Faith To The Awakening Of Self, Monique Swaby Sep 2013

The Spirituality Of Conciousness: From Mindfulness To Faith To The Awakening Of Self, Monique Swaby

Graduate College Dissertations and Theses

This thesis is an exploration of the concepts of what the spirituality of consciousness means in several key areas of the intellectual, emotional, and spiritual self. Many students and professionals walk through their educational and professional careers filled with confusion, lack of self-understanding, a yearning for something more but never discovering it in the places we find ourselves for most of our day-to-day interactions. My hope is that this thesis will give insight to how students can overcome obstacles and fears in their lives in order to move forward, and, when necessary, to move past themselves. As a young, Black, …


Investigation Of Subsonic And Supersonic Flow Characteristics Of An Inductively Coupled Plasma Facility, Silas Smith Sep 2013

Investigation Of Subsonic And Supersonic Flow Characteristics Of An Inductively Coupled Plasma Facility, Silas Smith

Graduate College Dissertations and Theses

Inductively Coupled Plasma (ICP) facilities create high enthalpy ows to recreate atmospheric entry conditions. Although no condition has been duplicated exactly in a ground test facility, it is important to characterize the condition to understand how close a facility can come to doing so. An ICP facility was constructed at the University of Vermont for aerospace material testing in 2010. The current setup can operate using air, carbon dioxide, nitrogen, and argon to test samples in a chamber. In this work we investigate di erent ways to increase measured heat ux and expand our facility to operate supersonically. To do …


Rejection Sensitivity As Mediator Between Stigma And Romantic Relationship Satisfaction, Jennifer Zangl Sep 2013

Rejection Sensitivity As Mediator Between Stigma And Romantic Relationship Satisfaction, Jennifer Zangl

Graduate College Dissertations and Theses

HIV/AIDS is a highly stigmatizing condition that dramatically influences the social relations of those infected with the disease (Herek & Glunt, 1988; Kalichman, 2000). Stigmatized individuals experience interpersonal rejection because of their stigma and this rejection can heighten dispositional sensitivity to rejection (Downey & Feldman, 1996). Increased sensitivity to interpersonal rejection has been shown to decrease relationship satisfaction and lead to relationship dissolution (Downey, Freitas, Michaelis, & Khouri, 1998). Few studies have examined the influence of stigmatization on romantic relationships and little is known about the romantic relationships of people living with HIV/AIDS. The current study examined the role of …


Happiness And The Patterns Of Life: A Study Of Geolocated Tweets, Morgan R. Frank, Lewis Mitchell, Peter Sheridan Dodds, Christopher M. Danforth Sep 2013

Happiness And The Patterns Of Life: A Study Of Geolocated Tweets, Morgan R. Frank, Lewis Mitchell, Peter Sheridan Dodds, Christopher M. Danforth

College of Engineering and Mathematical Sciences Faculty Publications

The patterns of life exhibited by large populations have been described and modeled both as a basic science exercise and for a range of applied goals such as reducing automotive congestion, improving disaster response, and even predicting the location of individuals. However, these studies have had limited access to conversation content, rendering changes in expression as a function of movement invisible. In addition, they typically use the communication between a mobile phone and its nearest antenna tower to infer position, limiting the spatial resolution of the data to the geographical region serviced by each cellphone tower. We use a collection …


Further Discussion On The Treatment Of Hypertension, Jessica Kim Md Sep 2013

Further Discussion On The Treatment Of Hypertension, Jessica Kim Md

Family Medicine Scholarly Works

Hypertension is a common primary care problem with guidelines to help with management, however recent studies have shown there may be important considerations in blood pressure management. Blood pressure varies during different times of day, and one summarized study showed significant benefits to taking blood pressure medications at bedtime on major cardiovascular events. In addition, individual variation in blood pressure may also pose a difference in stroke risk and certain medications address this variation better than others. A systematic review and meta-analysis are summarized that address these issues.


Secretin-Modulated Potassium Channel Trafficking As A Novel Mechanism For Regulating Cerebellar Synapses , Michael Williams Sep 2013

Secretin-Modulated Potassium Channel Trafficking As A Novel Mechanism For Regulating Cerebellar Synapses , Michael Williams

Graduate College Dissertations and Theses

The voltage-gated potassium channel Kv1.2 is a critical modulator of neuronal physiology, including dendritic excitability, action potential propagation, and neurotransmitter release. However, mechanisms by which Kv1.2 may be regulated in the brain are poorly understood. In heterologous expression systems Kv1.2 is regulated by endocytosis of the channel from the plasma membrane, and this trafficking can be modulated by adenylate cyclase (AC). The goal of this dissertation was to determine whether AC modulated endocytic trafficking of endogenous Kv1.2 occurred in the mammalian nervous system. Within the brain, Kv1.2 is expressed at its highest levels in the cerebellar cortex. Specifically, Kv1.2 is …


Parental Environments And Interactions With Conspecifics Alter Salinity Tolerance Of Offspring In The Annual Medicago Truncatula, Brenna M. Castro, Ken S. Moriuchi, Maren L. Friesen, Mounawer Badri, Sergey V. Nuzhdin, Sharon Y. Strauss, Douglas R. Cook, Eric Von Wettberg Sep 2013

Parental Environments And Interactions With Conspecifics Alter Salinity Tolerance Of Offspring In The Annual Medicago Truncatula, Brenna M. Castro, Ken S. Moriuchi, Maren L. Friesen, Mounawer Badri, Sergey V. Nuzhdin, Sharon Y. Strauss, Douglas R. Cook, Eric Von Wettberg

College of Agriculture and Life Sciences Faculty Publications

Summary: Based on expectations of the stress-gradient hypothesis for conspecific interactions, stress-sensitive genotypes may be able to persist in stressful environments when positive interactions between individuals occur under stressful environments. Additionally, we test how parental environmental effects alter responses to stress and outcomes of conspecific interactions in stress. While the stress-gradient hypothesis focuses on plant growth, earlier flowering may provide stress avoidance in short-lived organisms. We studied responses to soil salinity and conspecific neighbour using genotypes of Medicago truncatula (Fabaceae) originating from saline or non-saline environments, utilizing seeds from parental plants grown in saline or non-saline environments. During the early …

Rubenstein School of Environment and Natural Resources Faculty Publications

Agriculture is considered to be "climate-smart" when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development because of its capacity to unite the agendas of the agriculture, development and climate change communities under one brand. In this opinion piece authored by scientists from a variety of international agricultural and climate research communities, we argue that the concept needs to be evaluated critically because the relationship between the three dimensions is poorly understood, such that practically any improved agricultural practice can be considered climate-smart. This lack of …
