Dune And Coastal Evolution In Isla Salamanca National Park, Colombia, Juan Felipe Gómez

Theses and Dissertations (Comprehensive)

This project analyzes natural variables influencing the coastal and dune evolution in Isla Salamanca National Park (ISNP), a biosphere reserve and Ramsar site located in Colombia, on the Caribbean coast. Since at least the early 1950s, the park has been affected by eroding trends along most of the shoreline. Particularly, most modern dunes are located close to the coastline, forming scarped dunes regularly affected by storm wave-action.

The trends through time of rain, bathymetry and coastline changes during the last six decades were studied through statistical analysis, mapping of landscape features, and satellite images and historical aerial photograph …

Exploring Daily Dietary Behaviour Through Examination Of The Food Choice Process, Ivy Dam

Theses and Dissertations (Comprehensive)

As obesity rates continue to rise, the negative health impacts associated with unhealthy food choice behaviour remain an issue of concern. Observing the connection between food consumption and weight gain alone is likely not sufficient to understanding people’s construction of food choices. More detailed examination of a novel concept, the overall food choice process (FCP), including food thoughts, plans, purchases, and preparation, leading up to food intake/consumption may contribute to an improved understanding of food choice behaviour.

This thesis explored the wider FCP that gives rise to observed food consumption by testing passive video recording technologies, …

Exploring The Moments And Memory Of Tourist Experiences In Peru, Sarah Quinlan Cutler

Theses and Dissertations (Comprehensive)

Tourist experiences offer anomalous and complex interactions between tourists and tourism places. The study of these experiences is the focus of this doctoral dissertation, which aims to explore subjective aspects of the tourist experience. This exploration involves the conceptualisation of tourist experiences and the development of a multi-phased research design that captures the perceptions of momentary in situ experiences and examines how these perceptions change over time.

The dissertation addresses under studied areas in tourism and answers calls for research into immediate conscious experiences and tourist centred methodology. This investigation into tourist experiences involves 21 participants who took an educational …

The study of ecological services (ESs) is fast becoming a cornerstone of mainstream ecology, largely because they provide a useful means of linking functioning to societal benefits in complex systems by connecting different organizational levels. In order to identify the main challenges facing current and future ES research, we analyzed the effects of the publication of the Millennium Ecosystem Assessment (MEA, 2005) on different disciplines. Within a set of topics framed around concepts embedded within the MEA, each co-author identified five key research challenges and, where feasible, suggested possible solutions. Concepts included those related to specific service types (i.e. provisioning, …

On The Uncertainty Of Sea-Ice Isostasy, Cathleen Geiger, Peter Wadhams, Hans-Reinhard Müller, Jacqueline Richter-Menge

Dartmouth Scholarship

During late winter 2007, coincident measurements of sea ice were collected using various sensors at an ice camp in the Beaufort Sea, Canadian Arctic. Analysis of the archived data provides new insight into sea-ice isostasy and its related R-factor through case studies at three scales using different combinations of snow and ice thickness components. At the smallest scale (<1 m; point scale), isostasy is not expected, so we calculate a residual and define this as �� (‘zjey’) to describe vertical displacement due to deformation. From 1 to 10 m length scales, we explore traditional isostasy and identify a specific sequence of thickness calculations which minimize freeboard and elevation uncertainty. An effective solution exists when the R-factor is allowed to vary: ranging from 2 to 12, with mean of 5.17, mode of 5.88 and skewed distribution. At regional scales, underwater, airborne and spaceborne platforms are always missing thickness variables from either above or below sea level. For such situations, realistic agreement is found by applying small-scale skewed ranges for the R-factor. These findings encourage a broader isostasy solution as a function of potential energy and length scale. Overall, results add insight to data collection strategies and metadata characteristics of different thickness products.

The State Of Sachets: Ghana’S Private Sector Solution To A Public Infrastructure Problem, Robert J. Little

Pitzer Senior Theses

Known colloquially as “purewater”, sachet water has outcompeted all alternatives to Ghana’s unreliable government water infrastructure and serves as the cheap, portable, omnipresent solution for narrowing the safe water access gap. Each single-use sachet holds 500 ml of filtered potable water and is heat-sealed in a high-density polyethylene bag. Insufficient and often skeptical scholarship exists surrounding the state of sachet water in Ghana, and almost no research incorporates qualitative data into analysis and future recommendations. In the face of incomplete and decontextualized research on sachet water, this study aims to use qualitative data concerning Ghanaian viewpoints to showcase the …

Roots Versus Wells: Grassroots Activism Against Fracking In New York And California, Shannon J. Leap

Pitzer Senior Theses

The reliance upon and depletion of fossil fuels as an energy source puts pressure on individuals, communities, energy companies, and policy-makers. Hydraulic fracturing – known colloquially as fracking – as a method of drilling for oil and natural gas temporarily alleviates this pressure since it allows for the extraction previously inaccessible fossil fuels in shale rock deposits deep beneath the Earth’s surface. This has resulted in a nationwide “fracking boom,” which has come with its share of economic benefits. However, the process of fracking can be detrimental to human and environmental health. In reaction to the increasing development of this …

Electronic Theses and Dissertations

The purpose of this mixed-method phenomenological study is to understand the beliefs and attitudes that mid-career secondary school teachers have regarding the teacher evaluation process and its effect on their professional practice. Mid-career secondary school teachers (defined as having between 14-21 years of classroom experience) from Bayview Public Schools were selected to participate. A total of 152 mid-career secondary school teachers completed an electronic survey. Additionally, a total of 9 participants took part in one-on-one semi-structured interviews. The theoretical framework used to guide the study was the theory of planned behavior (TPB) (Ajzen, 1988; 1991) and Bandura*s theory of self-efficacy …

A Physiocratic Systems Framework For Open Source Agricultural Research And Development, Dorn Cox

Doctoral Dissertations

This dissertation presents a new participatory approach to agricultural research and development. It surveys the biological, sociological, economic, and technical landscape and proposes a framework for adaptive management based on the 18th century Physiocratic school of land-based economics. Industrial specialization and heavy emphasis on deductive approaches to science have contributed to the disconnection of large portions of the population from natural systems. Conventional agriculture and agricultural research methods following this pattern have created expensive social, environmental, and economic external costs, while adaptive management and resilient agricultural systems have been hindered by the cost and complexity of quantifying environmental services. However, …

Silvopasture In The Northeastern United States, Joseph Nathan Orefice

Doctoral Dissertations

Silvopasture, the sustainable integration of livestock and trees on the same unit of land, may have the potential to contribute to agricultural productivity in the Northeastern United States and concurrently encourage the ecosystems services which trees provide. Extremely little is known regarding the ecological characteristics of silvopastures being utilized, their social and economic drivers, or their agricultural productivity. Silvopasture characteristics, management, and reasons for use were documented through a purposeful sample of silvopasture practitioners in New York and New England. Results document the functional role of silvopastures on regional farms. This research also investigated the ecological and production dynamics of …

Hybrid Zone Dynamics Between Saltmarsh (Ammodramus Caudacutus) And Nelson's (Ammodramus Nelsoni) Sparrows, Jennifer Walsh

Doctoral Dissertations

Hybrid zones in nature have long been equated to “windows on the evolutionary process” providing unique environments to understand patterns of gene flow and introgression and the role of these mechanisms in maintaining biodiversity. Ongoing hybridization and introgression can lead to a number of conservation and evolutionary outcomes; as such, identifying the role of introgression in natural populations can provide new insights into species interactions while contributing to our understanding of evolutionary theory.

The research presented below characterizes hybrid zone dynamics between two tidal marsh endemics – the Saltmarsh (Ammodramus caudacutus) and Nelson’s (Ammodramus nelsoni) sparrow. Both species co-inhabit salt …

Catch Share Management In The Northeast Multispecies Fishery: Implications For The Commercial Groundfish Fishery In New Hampshire, Rachel G. Feeney

Doctoral Dissertations

This dissertation tests theories about catch share approaches to fishery management, examining their validity and limits relative to the Northeast groundfish sector program, and potentially modifies them in light of research outcomes. Participants of the groundfish fishery based in New Hampshire are the particular focus of research, but broader impacts are considered. Studies of this catch share program have been limited to date, and studies of catch share programs generally have focused on a particular dimension (e.g., biological, social, economic) rather than integrate across dimensions, despite increasing needs to do so for management. Here, six key aspects of fishing are …

Developing Microbial Biomarkers To Non-Invasively Assess Health In Wild Elk (Cervus Canadensis) Populations, Samuel B. Pannoni

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The composition of the intestinal bacterial community (intestinal microbiome) of mammals is associated with changes in diet, stress, disease and physical condition of the animal. The relationship between health and the microbiome has been extensively demonstrated in studies of humans and mice; this provides strong support for its potential utility in wildlife. When managing elk (Cervus canadensis), federal and state agencies currently must rely on invasive sampling and coarse demographic data on which to base their decisions. By developing microbiome-based biomarkers that vary as a function of elk body condition and disease (i.e. microbial biomarkers), we hope to …

Rediscovery Of A Native American Cultural Landscape: The Chickasaw Homeland At Removal, Michael D. Walls

Theses and Dissertations--Geography

Little information beyond generalities exists regarding the cultural landscape of the Chickasaw Indians in their ancestral homelands prior to Removal in the late 1830s. This dissertation evaluates one possible archival source for specifics of Chickasaw land use, the field notes and survey plats compiled as part of the Public Land Survey System (PLSS). The process of original survey following land cession treaty divided the ceded area up into the familiar square-mile rectangular system of townships and ranges that extends from the Mississippi Territory westwards, in the so-called public land states.

The research compiles all cultural observations made by the surveyors …

Insights Into Perspectives On Environmental Sustainability, Amber R. Shobe

Theses and Dissertations--Community & Leadership Development

As scientists become more aware of the imposing threats associated with climate change, university leaders are encouraged to become familiar with the principles of sustainability. Abundant research already supports the relevance of environmental sustainability in higher education; however, there exists a gap in the literature which investigates an understanding of environmental sustainability and the implementation of its practices. By examining colleges at the University of Kentucky, this study identifies organizational barriers to recognizing a thorough understanding of environmental sustainability at the departmental level. The results indicate that out of the eight colleges selected, two have no existing environmental sustainability programs …

The Use Of Improved Technology And Market-Based Incentives To Increase Forest Resource And Biodiversity Conservation In Rwanda, Kelly M. Rayens

Theses and Dissertations--Forestry and Natural Resources

This study evaluated the effectiveness of two distinct approaches to ecosystem conservation in Rwanda’s Nyungwe National Park: cookstove technology adoption and market-based policy instruments. A June 2014 survey of 250 households revealed that use of improved cookstove technology dramatically decreased fuelwood consumption for households in rural Rwanda, but that design, engineering and conflicting policy issues can hamper the widespread use of energy-efficient cooking technology. The second component of this research used the analytic hierarchy process (AHP) within a multi-criteria analysis (MCA) framework to explore the options for designing and implementing market-based instruments around the country’s conservation targets, particularly the highly …

Significance Evaluation Of The Forgotten Creek Site, Joy D. Ferry

All Master's Theses

Archaeological research has recognized the importance of montane environments in the subsistence and settlement strategies of pre-contact peoples. Yet little is understood about variation in the manner in which pre-contact peoples were using upland environments. In order to ascertain whether there is functional and/or technological variation between montane sites in comparable environmental settings, four lithic assemblages (45PI406, 45PI408, 45PI429, and 45PI438) from sites in the upper maritime forest and subalpine zone of Mount Rainier were compared. An evolutionary archaeology model was applied to define and measure variables relevant to stone tool manufacture and use. Statistically significant non-random associations were contextualized …

Land Use And Climate Change Bubbles: Resilience, Retreat, And Due Diligence, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

This Article examines events on the ground in several localities where climate change is lowering property values and analyzes how those changes in value can be reckoned with by regulators. It merges practices and principles of real estate transactions and finance with those of land use and environmental regulation.

Climate change is a planetary phenomenon whose environmental implications are far-reaching. Reports on climate change consequences increasingly focus on what is happening locally and presently, while speculation continues about long-term global consequences. In numerous communities, property values are declining because of repeated flooding, continued threats of storm surges, sustained high temperatures, …
