Though the basic purpose of MPAs is marine ecosystem conservation, the question of their influence on the local economy is often critical since it governs their social acceptability. This paper addresses the
problem of measuring the local economic impact of MPAs, on the basis of a comparative analysis of socio-economic...
Though the basic purpose of MPAs is marine ecosystem conservation, the
question of their influence on the local economy is often critical since it
governs their social acceptability. This paper addresses the problem of
measuring the consequences of creating a marine protected area (MPA) on
recreational extractive and non-extractive uses...
Since the early 1980s, satellite imagery has been commonly used to detect change
in wetlands. The overall objective of this study is to utilize remote sensing and
Geographic Information Systems (GIS) technology to determine the extent of change of
the wetland area and of other land use and land cover...
Antarctic Ice Sheet mass balance and, hence, sea level change is affected by the floating extensions of outlet glaciers and ice streams that take up about 44% of the coastline (Drewry et al., 1982) and are referred to as "ice shelves". Ice sheet mass loss accelerates when these ice shelves...
The mangrove ecosystem has served as a life-support system to large populations of coastal dwellers in Ecuador for many generations. Diverse communities comprised of multi-racial and multi-ethnic groups have formed along the edge of the mangrove forests throughout the Ecuadorian coast. These groups self-identify as being part of an “ancestral”...
Small-scale land acquisitions are transforming long-standing human-land relations in West Africa. In particular, high rates of urban population growth lead to the transfer of land from non-market customary tenure systems to market-based, formal land tenure regimes on the edges of cities. The literature suggests that the conversion process from inalienable...

This paper discusses a new approach to the design of operating systems. We view the jobs or tasks in this system as a number of small independent steps or functions which are sequenced together to produce a desired result. The concepts upon which this operating system is based are drawn...
Dimensional stability of wood-based composites with changing moisture content remains an important challenge in the industry for many applications. Wood modification technologies have shown significant improvement in dimensional stability by altering the chemistry of the wood substrate, or by filling the available space in the wood microstructure that otherwise would...
Flax fibers are frequently used as a sustainable and recyclable reinforcement for composite materials in aesthetic applications (ex. car interiors). Flax fibers are biodegradable and can be sustainably harvested. Furthermore, the question of how to dispose of flax reinforced materials after the end of their lifetime can be solved in...
Both conflicts and new identities result when indigenous' traditional values of landscape and resource management are superimposed with federal governments' management of archaeological and forest resources in federally designated protected areas. This thesis examines the relationship and discourse between two Cuicatec towns in Oaxaca, Mexico and three Mexican government agencies...
This study examines the impact of two decades of neoliberal policy reform on food production and household livelihood security in three West African countries. The rice sectors in The Gambia, Côte d’Ivoire, and Mali are scrutinized as well as cotton and its relationship to sorghum production in Mali. Although market...
International development programs are often implemented with the goal of building community resilience, but without a clear articulation of how this goal will be met, or any consideration of if or why the effort was successful after it has concluded. This thesis considers three different activities implemented by the U....
In this era of free trade and globalization, food is traveling greater and greater distances to its consumers. This is causing small farms and small farmers all over the world to protest as their livelihood is being undercut by cheap agricultural commodities from outside their communities. In the Ecuadorian Andes,...
Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...
The frontlines of climate change adaptation will occur in rural, impoverished regions of the world where households engage in climatically dependent livelihoods, such as peasant agriculture or pastoralism. As changing climate and changing markets affect the suite of household livelihood assets (environmental, social, and economic) which enable a household to...
High performance dielectric materials are needed for high power SiC- or GaN-based electronics which combine the best features of high energy density, low dielectric loss and high reliability and for advanced high-speed and high-voltage energy storage where temperature stability plays an important role in material properties. An ideal capacitor for...
Although dam construction has been an integral tool in development initiatives for nearly a century, dams can have significant negative impacts on local residents, particularly those who are permanently displaced from their homes and must be resettled elsewhere. Dams have unique impacts on indigenous peoples. As a result, many dam...

Sea surface temperature (SST) fronts are determined for the 2001–2004 time period
from Geostationary Operational Environmental Satellites (GOES) data in the California
Current System (CCS). The probability of detecting a SST front at an individual pixel
location in the CCS is presented as a bi-monthly climatology. Fronts clearly indicate the...
Several crops have recently been identified as potential dedicated bioenergy feedstocks for the production of power, fuels, and bioproducts. Despite being identified as early as the 1980s, no systematic work has been undertaken to characterize the spatial distribution of their long-term production potentials in the United states. Such information is...
Community colleges in the United States have become an important educational destination for international students. According to the Institute of International Education (IIE, 2006), international students who enrolled for the first time at a U.S. campus increased by 8 per cent, from 131,946 students in 2004/2005 to 142,923 in 2005/2006....
This dissertation investigates livelihood and land use change dynamics in a community at the farm-forest periphery in highland Ethiopia. I use interviews and livelihood assessment data to compare the strategies used by members of different wealth groups to negotiate and maintain access to forest resources, and integrate socioeconomic, bio-physical and...
Forest plantations in the Pacific Northwest are highly productive and have been intensively managed to maximize tree growth with practices such as Forest Vegetation Management (FVM). Different FVM regimes have been shown to enhance forest establishment by reducing the competition between the planted seedlings and early-seral vegetation. To better understand...
A fundamental objective of ecology and population biology is to identify factors that drive population dynamics and determine the population-level consequences of their interaction with the environment. Studies of reproductive performance can illuminate population dynamic processes, including the links between organismal biology, the environment, and life history theory. A central...
Using plant fibers as a potential renewable material to substitute for glass fibers in fiber-reinforced polymer composites has been growing since the late 1990s. Due to high demand, there has been a shift towards ‘green concept’ material in many applications. Numerous secondary plant fibers have been explored as a source...
The use of clonal varieties in forestry offers great potential to improve growth traits (quantity) and wood properties (quality) of loblolly pine (Pinus taeda L.). Loblolly pine trees established via somatic embryogenesis (clones), full-sib zygotic crosses, and half-sib zygotic open-pollinated families were sampled to identify variation in growth and wood...
Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate:coenzyme A ligase (4CL) has been reported as a
means for reducing lignin content in cell walls and increasing overall growth rates, thereby improving feedstock quality for
paper and bioethanol production. Using hybrid poplar (Populus tremula 3 Populus alba), we applied this...
Endoxifen has recently been identified as the predominant active metabolite of tamoxifen and is currently being developed as a novel hormonal therapy for the treatment of endocrine sensitive breast cancer. Based on past studies in breast cancer cells and model systems, endoxifen classically functions as an anti-estrogenic compound. Since estrogen...
Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic...
The ecologically and socio-economically important marine ecosystems of Europe are facing severe threats from a variety of human impacts. To mitigate and potentially reverse some of these impacts, the European Union (EU) has mandated the implementation of the Marine Strategy Framework Directive (MSFD) in order to achieve Good Environmental Status...
Since 1935, France has introduced a set of strict national wine rules and regulations, the Appellation d’Origine Contrôlée (AOC). The AOC limits fraud and oversees quality control by basing the rules on terroir. High quality from terroir comes has both physical and cultural factors. Before 1935, France produced a variety...
Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
Meta-analyses of field studies have shown that biomass, density, species richness, and size of organisms protected by no-take marine reserves generally increase over time. The magnitude and timing of changes in these response variables, however, vary greatly and depend upon the taxonomic groups protected, size and type of reserve, oceanographic...
Of the major players in the birth and growth of nuclear technology, France and the United States are two of the biggest. Their glaring differences in culture and political regimes, therefore, have resulted in two very different attitudes toward adoption and implementation of nuclear power. Through extensive literary research, cultural...
