Factors Affecting Developing Planning In Africa: The Need For Local Input, Ismael Sow

Dissertations and Theses

Africa has become synonymous with poverty, diseases, and despair. The continent is home to the highest number of extremely poor people in the world. Throughout the world, especially in the last few decades, many countries in the so-called South have succeeded in lifting their people out of poverty. The continent, with the exception of a few African countries, has failed to design and implement sound economic plans to bring prosperity to a billion Africans. This thesis proposes that for African countries to develop, ways should be found to include indigenous input into development planning. This assumption is based on both …

The Objective Vs. The Perceived Environment: What Matters For Active Travel, Liang Ma

Dissertations and Theses

This study aims to explore the relationship between the objective (actual) environment and people's perceptions of the environment, and their relative effects on active travel behavior, particularly bicycling behavior. This is an important research gap in the current literature linking the built environment and active travel. Better understanding this relationship will help to explore the mechanism underlying the built environment- behavior relationship and identify potential interventions to promote active travel.

Relying on the data from Portland, OR, this study investigated the following four research questions: (1) How does the objectively measured environment correspond to the perceived environment? And what factors …

Changing The Face Of The Earth: The Morrison-­Knudsen Corporation As Partner To The U.S. Federal Government, Christopher S. Blanchard

Dissertations and Theses

Beginning with reclamation projects in the western U.S., the heavy construction industry helped the federal government grow in size and sophistication in the twentieth century. The Morrison-­Knudsen Corporation throughout the twentieth century represented one of the federal government's favored contractors. Following western reclamation projects, the U.S. federal government then used contractors to help move the U.S. economy out of the Depression, prepare for World War II, wage the Cold War at home and abroad, and win the space race. Thus, at key stages in United States history we observe the necessity of the U.S. federal government partnering with the heavy …

Using Art To Teach Students Science Outdoors: How Creative Science Instruction Influences Observation, Question Formation, And Involvement, Christina Schull Cone

Dissertations and Theses

Elementary education has become increasingly divided into subjects and focused on the demand for high math and reading scores. Consequently, teachers spend less time devoted to science and art instruction. However, teaching art and science is crucial to developing creative and rational thinking, especially for observation and questioning skills. In this study, third grade students attending an urban school in Portland, Oregon received instruction of an art strategy using observational and quantifying drawing techniques. This study examines, "Will an art strategy observing the local environment help students make observations and ask questions?" and "In what ways are student learning and …

Agricultural Classification Of Multi-Temporal Modis Imagery In Northwest Argentina Using Kansas Crop Phenologies, Jarrett Alexander Keifer

Dissertations and Theses

Subtropical deforestation in Latin America is thought to be driven by demand for agricultural land, particularly to grow soybeans. However, existing remote sensing methods that can differentiate crop types to verify this hypothesis require high spatial or spectral resolution data, or extensive ground truth information to develop training sites, none of which are freely available for much of the world. I developed a new method of crop classification based on the phenological signatures of crops extracted from multi-temporal MODIS vegetation indices. I tested and refined this method using the USDA Cropland Data Layer from Kansas, USA as a reference. I …

The Effect Of Social Media On Public Awareness And Extra-Judicial Effects: The Gay Marriage Cases And Litigating For New Rights, Sarahfina Aubrey Peterson

Dissertations and Theses

When the Supreme Court grants new rights, public awareness is a crucial part of enforcement. Gerald N. Rosenberg and Michael J. Klarman famously criticized minority rights organizations for attempting to gain new rights through the judiciary. The crux of their argument relied heavily on the American media's scanty coverage of Court issues and subsequent low public awareness of Court cases. Using the 2013 United States v. Windsor and Hollingsworth v. Perry rulings as a case study, I suggest that the media environment has changed so much since Rosenberg and Klarman were writing that their theories warrant reconsideration. Minority rights groups …

"But There's A Black History Month": A Content Analysis Of Ideological Framing And Presentation In White Nationalist Publications, Dylan Tomas Waite

Dissertations and Theses

The political climate in America continues to become more polarized each year. The "left" and "right" political parties are locked in near-constant struggle and it is often the people whom they are meant to serve that suffer the harshest effects of this struggle. This mainstream political posturing and hostile behavior has allowed for the continued presence, and some say resurgence, of racially motivated right-wing nationalist groups. Groups such as the Ku Klux Klan, the Aryan Nations and racist Skinheads have seen periods of strength and decline throughout American history. In the late 20th and early 21st Centuries they have begun …

The Ground Slate Transition On The Northwest Coast: Establishing A Chronological Framework, Joshua Daniel Dinwiddie

Dissertations and Theses

This thesis establishes the earliest appearance of ground slate points at 50 locations throughout the Northwest Coast of North America. Ground slate points are a tool common among maritime hunter-gatherers, but rare among hunter-gatherers who utilize terrestrial subsistence strategies; ground slate points are considered one of the archaeological hallmarks of mid-to-late Holocene Northwest Coast peoples. The appearance of ground slate points in the archaeological record is frequently marked by a concurrent decline in the prevalence of flaked stone points, a phenomenon often referred to as "the ground slate transition." Until now, the specific timing of the appearance of these tools …

Controlling The Empire: Measuring Ethnic Residential Segregation In London, 2001-2011, Lindsay Joella Spell

Dissertations and Theses

This research presents an overview of ethnic residential segregation in London, England, from 2001 to 2011 using four different methods of measurement. The purpose of the study was to both examine changes in the level of segregation among different ethnic groups between census dates and to compare various methods of measurement. Using the Index of Dissimilarity, Poulsen et al.'s (2001) typology classification and two different local statistics (Getis-Ord G* and Anselin Local Moran's I), the levels of concentration of the five main ethnic minority groups in London were measured for data from the 2001 and 2011 censuses. The five ethnic …

Socio-Spatial Transformation And Contested Space At The Street Level In Latin America: The Case Of Cali, Colombia, Maria Janeth Mosquera Becerra

Dissertations and Theses

Since 2008, more than 50% of the world's population has lived in cities and it is projected that by 2050 around 87% will do so. Designing infrastructure in urban spaces has become increasingly critical for achieving human well-being. This dissertation examines socio-spatial transformation processes related to urbanization, economic development and the marginalization of utilitarian cycling in Cali, Colombia, as a particular expression of the struggle for transportation space occurring in urban areas. The research analyzes (a) the socio-spatial processes that have restricted the use of bicycles as a means of transportation in the city of Cali, Colombia; and (b) the …

Using Gist Features To Constrain Search In Object Detection, Joanna Browne Solmon

Dissertations and Theses

This thesis investigates the application of GIST features [13] to the problem of object detection in images. Object detection refers to locating instances of a given object category in an image. It is contrasted with object recognition, which simply decides whether an image contains an object, regardless of the object's location in the image.

In much of computer vision literature, object detection uses a "sliding window" approach to finding objects in an image. This requires moving various sizes of windows across an image and running a trained classifier on the visual features of each window. This brute force method can …

It's Complicated: The Role Of Facebook In Romantic Relationships Concerning Relational Certainty, Attachment, And Self-Esteem, Jenna Rae Tucker

Dissertations and Theses

Facebook is among the top used websites in the world, and research has shown that Facebook use is related to individual personality characteristics such as well-being and self-esteem. This study builds on previous research, expanding to investigate attachment-related anxiety and avoidance and relational certainty. The current study examined relationships between Facebook use (both general and for surveillance) and relational certainty, attachment-related anxiety and avoidance, and self-esteem in undergraduate students (N = 261). Online methods were used for data collection, and individuals with their relationship displayed on Facebook reported more relational certainty; however, the more time they spent on the site, …

An Analysis Of Vegetation Recovery Following Dam Removal At Hemlock Recreation Site, Washington, Greer Stewart Ramsey

Dissertations and Theses

Dam removals are becoming increasingly common as dams reach their life expectancy and face costly upgrades associated with relicensing. Though removal is often viewed as a success in terms of ecological restoration, it also represents a major disturbance to an area. Previous research has shown that native species do not survive as well at these disturbed sites, and invasive species often dominate. This study examines the vegetation response in the drained reservoir area after the removal of Hemlock Dam on Trout Creek, a tributary to the Wind River in southern Washington. Transects were established and quadrats were sampled to determine …

Implications Of Local And Regional Food Systems: Toward A New Food Economy In Portland, Oregon, Michael Mercer Mertens

Dissertations and Theses

The local food movement in the Portland Metro Region of Oregon is as prevalent as anywhere in the Country. To a large degree this is driven by the Portland Metro area food culture and the diverse agricultural landscape present in the Willamette Valley and throughout the State. Portlanders demand local food and thus far the rural periphery has been able to provide it; driving a new food economy that has economic implications throughout the region. As this regional food economy emerges much attention has been focused on harnessing its power for economic development perpetuated by the belief that there exists …

Does Voluntary Reading Matter? The Influences Of Voluntary Reading On Student Achievement, Maika J. Yeigh

Dissertations and Theses

Does voluntary reading matter? While there is much known about the benefits to children who engage in sustained silent reading, commercial reading programs implemented as a result of No Child Left Behind often displace time for children to silently read (NCLB, 2002). An increase in the amount of time children spend with a commercial reading program has meant a decrease in time provided for in-school voluntary reading during the elementary literacy block (Brenner & Hiebert, 2010). This quantitative study used the 2011 restricted-use National Assessment of Educational Progress (NAEP) data to determine whether opportunities provided to children for in-school voluntary …

Exploring Connections Between Efforts To Restrict Same-Sex Marriage And Surging Public Opinion Support For Same-Sex Marriage Rights: Could Efforts To Restrict Gay Rights Help To Explain Increases In Public Opinion Support For Same-Sex Marriage?, Samuel Everett Christian Dunlop

Dissertations and Theses

Scholarly research on the subject of the swift pace of change in support for same-sex marriage has evolved significantly over the last ten years. The shift has gone beyond the scholarship's initial description amongst demographic groups on how opinion has changed on gay rights issues, like same-sex marriage, to an examination of why the change has occurred. A great deal of the initial research on the topic seemed to focus on demographic traits that suggested a greater propensity toward support for same-sex marriage as time went on. Is the existent literature sufficient to explain why such a dramatic change in …

"Dangerous Subjects": James D. Saules And The Enforcement Of The Color Line In Oregon, Kenneth Robert Coleman

Dissertations and Theses

In June of 1844, James D. Saules, a black sailor turned farmer living in Oregon's Willamette Valley, was arrested and convicted for allegedly inciting Indians to violence against a settler named Charles E. Pickett. Three years earlier, Saules had deserted the United States Exploring Expedition, married a Chinookan woman, and started a freight business on the Columbia River. Less than two months following Saules' arrest, Oregon's Provisional Government passed its infamous "Lash Law," banning the immigration of free black people to the region. While the government repealed the law in 1845, Oregon passed a territorial black exclusion law in 1849 …

Assessing Hydrologic And Water Quality Sensitivities To Precipitation Changes, Urban Growth And Land Management Using Swat, Alexander Michael Psaris

Dissertations and Theses

Precipitation changes and urban growth are two factors altering the state of water quality. Changes in precipitation will alter the amount and timing of flows, and the corresponding sediment and nutrient dynamics. Meanwhile, densification associated with urban growth will create more impervious surfaces which will alter sediment and nutrient loadings. Land and water managers often rely on models to develop possible future scenarios and devise management responses to these projected changes. We use the Soil and Water Assessment Tool (SWAT) to assess the sensitivities of stream flow, sediment, and nutrient loads in two urbanizing watersheds in Northwest Oregon, USA to …

Ariège’S Development Conundrum, Alan Thomas Devenish

Dissertations and Theses

Since the latter half of the nineteenth century, industrialization and modernization have strongly shaped the development of the French department Ariège. Over the last roughly 150 years, Ariège has seen its population decline from a quarter million to 150,00. Its traditional agrarian economy has been remade for competition on global markets, and the department has relied on tourism to bring in revenue where other traditional industries have failed to do so. In this thesis I identify the European Union and French policies that continue to guide Ariège's development through subsidies and regulation. I explain the origins and effects of modernization …

Safety In Maize: Subsistence Agriculture In A Zapotec Migrant Town, Fiona Joy Gladstone

Dissertations and Theses

Subsistence maize production has long been a dominant economic activity of households in Santiago Apóstol, a Zapotec community in the Central Valley of Oaxaca, Mexico. A baseline study from 1973 documents a regionally pervasive form of household level agriculture whereby cultivators prioritize land for subsistence maize above commercial crops. Since then, much has transformed the face of rural Mexico, including migration to the United States. Migration accelerated beginning in the 1970s as a response to government disinvestment in maize, but it may also be a new force of cultural and economic change impacting agriculture. The question arises, has migration modified …

Household Water Demand And Land Use Context: A Multilevel Approach, Elizabeth Yancey Breyer

Dissertations and Theses

Urban water use arises from a mix of scale-dependent biophysical and socioeconomic factors. In Portland, Oregon, single-family residential water use exhibits a tightly coupled relationship with summertime weather, although this relationship varies with land use patterns across households and neighborhoods. This thesis developed a multilevel regression model to evaluate the relative importance of weather variability, parcel land use characteristics, and neighborhood geographic context in explaining single-family residential water demand patterns in the Portland metropolitan area. The model drew on a high-resolution panel dataset of weekly mean summer water use over five years (2001-2005) for a sample of 460 single-family households …

Code Switching Between Tamazight And Arabic In The First Libyan Berber News Broadcast: An Application Of Myers-Scotton's Mlf And 4m Models, Ashour S. Abdulaziz

Dissertations and Theses

The purpose of this study is to investigate the nature of code switching between Tamazight and Arabic in light of Myers-Scotton's Matrix Frame Model (MLF) (Myers- Scotton, 1993), and the 4-M model of code switching (Myers-Scotton & Jake, 2000). Data come from the very first Libyan Tamazight news broadcast in Libya on May 2, 2011, during the uprising against the Gaddafi regime. I analyzed the broadcast in an attempt to understand the nature and implications of the switching between the two languages in the utterances of the speakers in the video. I also argued that in many ways what many …

A Global Investigation Of Stakeholder And Contextual Influences On Firm Engagement In Sustainability, Annette M. Nemetz

Dissertations and Theses

Global sustainability issues cross all sectors of society, including businesses, governments, and communities and come with substantial costs. Business organizations are increasingly expected to address sustainability issues in a responsible manner and to disclose socially responsible behaviors accurately and transparently, showing that they are effective at managing and being proactive about sustainability challenges. In light of these pressures and expectations for business organizations, the fundamental research question for this study was whether variation existed in the levels of engagement in sustainability efforts across firms globally, and, more importantly, why such variation existed.

The level of strategic firm engagement in sustainability …

On Thin Ice? Domestic Violence Advocacy And Law Enforcement-Immigration Collaborations, Diana Rempe

Dissertations and Theses

The public focus on domestic violence has been one of the most successful campaigns of the modern women's movement. This success was achieved in part through the creation of strategic alliances among agencies and organizations responding to partner violence. One of the most contested of these alliances involved partnering with the criminal justice system. While representing an advance in holding police accountable in protecting all citizens (Coker, 2006), this alliance has had problematic consequences, particularly as it has extended state power into the lives of women of color (e.g. Richie, 2005). This problem is exacerbated by new collaborations between law …

Mapping Sociocultural Values Of Visitors On The Olympic Peninsula, Washington, Alexa North Todd

Dissertations and Theses

Contested land-management plans make spatial data about values that people attach to the landscape necessary for federal land management. The study area for this project is the Olympic Peninsula, Washington, an area that is divided by a complex mosaic of land jurisdictions, including public lands administered by the National Park Service, National Forest Service, and Washington State, as well as interspersed tribal and private landholdings surrounding the perimeter. During the summer of 2012, I collected map and survey data from visitors at fourteen popular destinations around the Olympic Peninsula, including visitor centers, campgrounds, trail access points, and a ferry. Three …
