Sustainability Policy’S Inherent Dilemmas – Exemplified Via Critical Examination Of The Las Vegas Metropolitan Sustainability Campaign, Kathryn A. Zimmerman

All Master's Theses

In response to a dual problem of critical water scarcity and rapid population growth, leaders of metropolitan Las Vegas implemented a region-wide, internationally marketed sustainability campaign. Preliminary studies found that, while sustainability policy attains its rhetorical goals, solutions initiated not only perpetuate but also purposefully expand the original dual problem to justify continuous water resource acquisitions. To examine this sustainability conundrum constructed by leadership—problem-perpetuation rather than problem-resolution—a critical examination in resource management asked two basic questions: what is being sustained and by what means? Via this inquiry, specific processes by which leaders perpetuate problems can be identified; and, so-informed, new …

Gesture Sequence In Captive Orangutans (Pongo Pygmaeus), Amanda Leone Carner

All Master's Theses

The most flexible form of communication may be gestures used by large body apes. The current study focused on gesture sequence in five captive orangutans at Woodland Park Zoo. We observed 305 gestures with 185 gestures (60.65%) occurring in 61 sequences in 2,482 minutes of data. Overall, orangutans used 272 tactile gestures (89 .18% ), 29 visual gestures (9 .50%) and 4 facial expressions ( 1.31 % ). In sequence, orangutans used 176 tactile gestures (95.14%), 7 visual gestures (3.78%), and 2 facial expressions (1.08%). Overall, a two-way repeated measure ANOV A showed significantly more tactile (x=26.9) than visual (x=2.9) …

The Benefits Of Breastfeeding, Avery Kordus

Senior Honors Theses

Breastfeeding research is plentiful, and the majority of the literature shows that breast milk is the superior form of infant nutrition except in the rare circumstances of infant metabolic disorders, maternal drug use, or positive HIV status. In comparison to formula, breast milk provides improved cognition, development, behavior, bonding, nutrition, digestion, immunity, and long-term health with fewer diseases and conditions in infants. Mothers are benefited by breastfeeding through bonding, faster weight loss, and reduction in certain cancers and conditions. Breast milk contains the proper amount of carbohydrates, fats, proteins, vitamins, and minerals, and is also specialized for each infant and …

Fishery Co-Management Opportunities Between Tribal And State Agencies: Conflict To Collaboration, J. Marty Holtgren

Dissertations, Master's Theses and Master's Reports - Open

Over the past 40 years global recognition has occurred for indigenous groups to be represented and have input in how natural resources are managed. This has largely occurred because of how management decisions have consequences to indigenous groups that reach beyond natural resource issues but into cultural, spiritual, social and political elements including sovereignty, legitimacy, justice, equity and empowerment and using indigenous paradigms to meet indigenous needs. In the United States numerous legal agreements have been reached that pair state and tribal agencies into co-management. This project concerns a recent co-management agreement between the State of Michigan and five Native …

Illuminating Capacity-Building Strategies For Landscape-Scale Collaborative Forest Management Through Constructivist Grounded Theory, Marcelle Elise Dupraw

Department of Conflict Resolution Studies Theses and Dissertations

This dissertation uses the constructivist grounded theory methods of Charmaz (2011) to explore: 1) the unique characteristics of landscape-scale collaboration; 2) implications for collaborative capacity-building strategies; and 3) the relationship between conflict, landscape-scale collaboration, and conflict resolution. The study was conducted through the US Forest Service's Collaborative Forest Landscape Restoration Program (CFLRP). In the 1980s and 1990s, national forest management conflicts brought the forest industry to a standstill, with many jobs lost. In addition, historic fire suppression practices have made our national forests highly vulnerable to catastrophic wildfire. Many have strong opinions about what should be done and how. The …

Health Promotion In Multiple Domains: Capitalizing On The Spillover Effect, Gabrielle Maria D'Lima

Psychology Theses & Dissertations

Lifestyle behaviors, such as physical activity and food consumption choices, play a critical role in the development of chronic diseases and ultimately mortality. Optimally, multiple health-related behaviors are changed to reduce risk rather than targeting only one risk behavior. The purpose of the current research was to examine the potential utility of the spillover effect in the application of a multiple health behavior intervention. The online intervention developed in this study aimed primarily to foster self-regulation, bolstered by impulsivity control and self-efficacy, in one health-related behavior (i.e., physical activity) in order to potentially affect change in other health-related behaviors (e.g., …

Successes And Challenges From Formation To Implementation Of Eleven Broad-Extent Conservation Programs, Erik A. Beever, Brady J. Mattsson, Matthew J. Germino, Max Post Van Der Burg, John B. Bradford, Mark W. Brunson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Integration of conservation partnerships across geographic, biological, and administrative boundaries is increasingly relevant because drivers of change, such as climate shifts, transcend these boundaries. We explored successes and challenges of established conservation programs that span multiple watersheds and consider both social and ecological concerns. We asked representatives from a diverse set of 11 broadextent conservation partnerships in 29 countries 17 questions that pertained to launching and maintaining partnerships for broad-extent conservation, specifying ultimate management objectives, and implementation and learning. Partnerships invested more funds in implementing conservation actions than any other aspect of conservation, and a program’s context (geographic extent, United …

A Gray Wolf (Canis Lupus) Delivers Live Prey To A Pup, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

A two-year-old sibling Gray Wolf (Canis lupus) carefully captured an Arctic Hare (Lepus arcticus) leveret alive on Ellesmere Island, Nunavut, Canada, and delivered it alive to a pup 28–33 days old. This appears to be the first observation of a Gray Wolf delivering live prey to a pup.

Finding Them Before They Find Us: Informatics, Parasites, And Environments In Accelerating Climate Change, Daniel R. Brooks, Eric P. Hoberg, Walter A. Boeger, Scott Lyell Gardner, Kurt E. Galbreath, David Herczeg, Hugo H. Mejía-Madrid, S. Elizabeth Rácz, Altangerel Tsogtsaikhan Dursahinhan

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of the ecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and global public need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulate a cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology of parasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation–assessment–monitoring–action (DAMA), suggests an integrated proposal to build a proactive capacity to understand, anticipate, and respond …

Anthropogenics: Human Influence On Global And Genetic Homogenization Of Parasite Populations, Dante S. Zarlenga, Eric P. Hoberg, Benjamin Rosenthal, Simonetti Mattiucci, Giuseppe Nascetti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The distribution, abundance, and diversity of life on Earth have been greatly shaped by human activities. This includes the geographic expansion of parasites; however, measuring the extent to which humans have influenced the dissemination and population structure of parasites has been challenging. In-depth comparisons among parasite populations extending to landscape-level processes affecting disease emergence have remained elusive. New research methods have enhanced our capacity to discern human impact, where the tools of population genetics and molecular epidemiology have begun to shed light on our historical and ongoing influence. Only since the 1990s have parasitologists coupled morphological diagnosis, long considered the …

Modeling Black Bear Population Dynamics In A Human-Dominated Stochastic Environment, David L. Lewis, Stewart W. Breck, Kenneth R. Wilson, Colleen T. Webb

United States Department of Agriculture Wildlife Services: Staff Publications

Many large carnivore populations exist in human-influenced stochastic environments where availability of natural food sources vary annually and anthropogenic food sources can supplement energetic demands, but at a potential demographic cost due to human–wildlife conflict and subsequent conflict management. Understanding how these competing factors influence a population is complex and difficult to study, but here we demonstrate the utility of using a stochastic projection matrix model and perturbation analysis to gain insight into this problem. We modeled a black bear population subjected to stochastic failures of fruiting and masting species, but with access to garbage in urban environments.We parameratized our …

An Exploratory Examination Of Families Engaged In An Adventure Running Kids Program, Heather Isnor

Theses and Dissertations (Comprehensive)

Academics and practitioners have only just begun to delve into the health benefits of outdoor activities in the last few years. In general, the forested settings of these activities have been documented to decrease stress levels, increase recovery rates from disease, and lessen the symptoms of mental illnesses (Kuo & Faber Taylor, 2004). It is believed that the natural environment acts as a setting where humans can engage in physical activity, aesthetic experiences, and social interactions that, in turn, release stress and lead to improved well-being (Bird, 2012). Currently, however, children are experiencing limited exposure to nature and which has …

A Bittersweet Investigation Of Availability And Nutritive Value As Determinants Of Volitional Sucrose Consumption, Milan D. Valyear

Theses and Dissertations (Comprehensive)

Rats given ~24 h access to a 4% sucrose solution every 3^rd day (E3DA) consume about 100 g more solution than rats with continuous, everyday access (EDA). Under the same EDA-E3DA conditions rats will consume similar amounts of a more concentrated 8 or 16% sucrose solutions (Eikelboom, Hewitt, & Adams, Unpublished). It maybe that with these more concentrated solutions rats hit a satiety limit that prevents a difference between EDA and E3DA consumption from being evident. Experiment 1 was conducted to investigate the effect of adding quinine to 4% and 8% sucrose solutions with the intention of reducing consumption …

Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

An increasing concern in poultry nutrition is the effects of mycotoxins in contaminated grain. Several new products have come onto the market that chemically bind these toxins preventing mycotoxicosis. However, many of these products have not been tested for safety if accidently overfed to broiler breeders. In order to simulate a feed mixing error at a feed mill, Improved Milbond-TX® was overfed to broiler breeders to see if this would cause any negative effects on bird performance. A typical corn-soybean based diet supplemented with Milbond-TX mycotoxin binder at three different levels of inclusion (0%, 0.5%, and 1%) was fed to …

Unintended Outcomes Of Farmers' Adaptation To Climate Variability: Deforestation And Conservation In Calakmul And Maya Biosphere Reserves, Claudia Rodriguez-Solorzano

Dartmouth Scholarship

Minimizing the impact of climate change on farmer livelihoods is crucial, but adaptation efforts may have unintended consequences for ecosystems, with potential impacts on farmers’ welfare. Unintended outcomes of climate adaptation strategies have been widely discussed, however, empirical exploration has been neglected. Grounded in scholarship on climate adaptation, environmental governance, social–ecological systems, and land-use change, this paper studies whether farmers’ climate adaptation contributes to deforestation or forest conservation. The paper draws on interviews with 353 farmers from 46 communities in Calakmul Biosphere Reserve in Mexico and Maya Biosphere Reserve in Guatemala. Farmers in the area of study have implemented adaptation …

Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek

Dissertations, Master's Theses and Master's Reports - Open

Over 2 million Anterior Cruciate Ligament (ACL) injuries occur annually worldwide resulting in considerable economic and health burdens (e.g., suffering, surgery, loss of function, risk for re-injury, and osteoarthritis). Current screening methods are effective but they generally rely on expensive and time-consuming biomechanical movement analysis, and thus are impractical solutions. In this dissertation, I report on a series of studies that begins to investigate one potentially efficient alternative to biomechanical screening, namely skilled observational risk assessment (e.g., having experts estimate risk based on observations of athletes movements). Specifically, in Study 1 I discovered that ACL injury risk can be accurately …

Application Of An Imputation Method For Geospatial Inventory Of Forest Structural Attributes Across Multiple Spatial Scales In The Lake States, U.S.A., Ram K. Deo

Dissertations, Master's Theses and Master's Reports - Open

Credible spatial information characterizing the structure and site quality of forests is critical to sustainable forest management and planning, especially given the increasing demands and threats to forest products and services. Forest managers and planners are required to evaluate forest conditions over a broad range of scales, contingent on operational or reporting requirements. Traditionally, forest inventory estimates are generated via a design-based approach that involves generalizing sample plot measurements to characterize an unknown population across a larger area of interest. However, field plot measurements are costly and as a consequence spatial coverage is limited. Remote sensing technologies have shown remarkable …

Beyond Roots Alone: Novel Methodologies For Analyzing Complex Soil And Minirhizotron Imagery Using Image Processing And Gis Tools, Justina A. Silva

Dissertations, Master's Theses and Master's Reports - Open

Quantifying belowground dynamics is critical to our understanding of plant and ecosystem function and belowground carbon cycling, yet currently available tools for complex belowground image analyses are insufficient. We introduce novel techniques combining digital image processing tools and geographic information systems (GIS) analysis to permit semi-automated analysis of complex root and soil dynamics. We illustrate methodologies with imagery from microcosms, minirhizotrons, and a rhizotron, in upland and peatland soils. We provide guidelines for correct image capture, a method that automatically stitches together numerous minirhizotron images into one seamless image, and image analysis using image segmentation and classification in SPRING or …

Understanding Traditions And Practices Of Medicinal Plant Use In Carhuamayo, Junin, Peru, Anastasia Orkwiszewski

Graduate Student Theses, Dissertations, & Professional Papers

Understanding and preserving Traditional Ecological Knowledge and Practices (TEKP) are essential for the continued resilience and cultural diversity of humanity. TEKP faces a multitude of threats from habitat loss, growth of the market economy, globalization, and acculturation. Medicinal plant use in the high Andean town of Carhuamayo, Junín, was studied to assess the vibrancy of that particular branch of TEKP in that area, in what parts of the population it was held, and what factors influence its loss or growth. Gender, age, migrant status, and acculturation levels were not found to be statistically significant in predicting medicinal plant knowledge. Analysis …

Federal V. State Effectiveness: An Analysis Of The Endangered Species Act And Current Potential Attempts At Reform, Nicholas Primo

Pepperdine Policy Review

In November 2013, several Congressional leaders drafted a new bill to reform the Endangered Species Act of 1973 (ESA). While the Endangered Species Management Self-Determination Act (ESMSDA) was the first major attempt at updating the crucial U.S. environmental policy in decades, it also inflamed environmentalist defenders of the original bill. More importantly, it raised several questions as to whether state or federal-oriented approaches to endangered species protection and environmental policy more broadly is ultimately more effective. This article analyzes the original 1973 ESA, followed by an analysis of the ESMSDA currently being considered. It will discuss the various strengths and …

Message Matters: Application Of The Theory Of Planned Behavior To Increase Household Hazardous Waste Program Participation, Amy Dyer Cabaniss

Antioch University Dissertations & Theses

Removing household hazardous waste (HHW) from the municipal solid waste stream is important to protect health, safety and the environment. Communities across the U.S. separate HHW from regular trash for disposal with hazardous waste, however nationally, participation rates are low with only five to ten percent of households estimated to participate in any given collection. This two-part study used the Theory of Planned Behavior (TPB) to understand individuals’ beliefs and attitudes toward HHW collections, and to develop a print message intervention to increase participation. In Study 1, respondents (N = 983) completed a survey administered to homeowners in the Connecticut …
