Last Mile Asset Monitoring: Low Cost Rapid Deployment Asset Monitoring, Zdenek Zumr

Dissertations and Theses

Installation and utilization of residential distribution transformers has not changed substantially over a long period of time. Utilities typically size their transformers based on a formula that takes into account broadly what types and how many dwellings will be connected.

Most new residential dwellings feature 200 Amp service per household with an anticipated energy demand of under 20,000 kWh per year. Average electrical energy consumption varies from state to state but averages to 11,280 kWh per year. Energy demand is expected to fall into a typical residential load curve that shows increased demand early in the morning, then decreasing during …

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 …

"Del Campo Ya Pasamos A Otras Cosas--From The Field We Move On To Other Things": Ethnic Mexican Narrators And Latino Community Histories In Washington County, Oregon, Luke Sprunger

Dissertations and Theses

This work examines the histories of the Latino population of Washington County, Oregon, and explores how and why ethnic Mexican and other Latino individuals and families relocated to the county. It relies heavily on oral history interviews conducted by the author with ethnic Mexican residents, and on archival newspaper sources. Beginning with the settlement of a small number of tejano families and the formation of an ethnic community in the 1960s, a number of factors encouraged an increasing number of migrant Latino families--from tejanos to Mexican nationals to Central and South Americans to indigenous migrants of various nationalities--to settle permanently …

Community Connections: Exploring The Constructive Potential Of Facebook For Civic Engagement, Sarah Ruth Martin

Dissertations and Theses

Recognizing the importance of civic engagement to the health of local communities and the overall success of a democracy, this research sought to better understand the relationship between online media use and civic engagement. Specifically, the constructive potential of the social networking site Facebook was explored using the theoretical framework of communication infrastructure theory (CIT; Ball-Rokeach, Kim, & Matei, 2001). Results of a cross-sectional survey with a national sample of 375 participants indicated that Facebook does hold potential for civic engagement. The two most important findings of the research were that Facebook facilitated connection to neighborhood storytelling and that connection …

Characterization Of Functional Domains Of Cul3, An E3 Ubiquitin Ligase, Using Chimeric Analysis, Jennifer Anne Mitchell

Dissertations and Theses

Modification of cellular proteins with molecules of ubiquitin is an important process that regulates the activity of cellular proteins. Cullin RING ligases (CRLs) are multi-subunit complexes that act in concert with E2 enzymes to attach molecules of ubiquitin to protein substrates. There are seven CRLs in mammalian cells (Cul1, Cul2, Cul3, Cul4A, Cul4B, Cul5, and Cul7) that are highly homologous in sequence and structure. CRLs possess a highly conserved C- terminal domain that interacts with E2 enzymes, and a more variable N- terminal domain which recruits substrates through distinct substrate adapter molecules. Despite the structural similarity, these CRLs recognize distinct …

The Relationship Between Mindfulness And Burnout Among Master Of Social Work Students, Jolanta Maria Piatkowska

Dissertations and Theses

Social work students frequently endure elevated levels of prolonged stress and psychological affliction that might result in serious consequences, such as development of burnout. Some experts suggest that burnout originates in the exposure to chronic interpersonal stressors in the work environment. Yet, there is emerging evidence suggesting that mindfulness practice might be beneficial in alleviating stress. Thus, the purpose of this exploratory study was to examine the relationship between mindfulness and burnout among Master of Social Work students. Burnout, mindfulness, religiosity, spirituality and their potential relationship were discussed and related to previous scholarly literature. Specifically, this study focused on testing …

Dissertations and Theses

The purpose of this thesis is to explore the experiences of single fathers and their roles as primary caregiver to their children as men in society adopting traditionally feminine roles. There was one primary research question explored: How do single father's experience parenthood? This is explored through four sub questions and discussions about daily life and childrearing alone; childcare and work and family conflicts; use of services and support networks; and of particular interest, gender and the influence of masculinity. Through an analysis of interviews with 14 fathers of varying class status, age, education, and time spent as a single …

The Role Of Diversity In Peer Influences On Students' Academic Engagement, Hyuny Clark-Shim

Dissertations and Theses

Children's classroom engagement is important for their learning and academic achievement. Extending Kindermann's (2007) study of peer influence on adolescents' engagement to an ethnically homogeneous sample, the current study examined how different aspects of diversity affect the peer influence process. Three types of diversity were considered: ethnic diversity existing at the school level, relational diversity at the peer network level, and motivational diversity at the group level. Ethnic diversity was observed in the student body as well as among school teachers and staff. Relational diversity was measured by z-scores resulting from binomial tests reflecting how closely two pair of individuals …

The Impact Of Wiki-Based Collaborative Writing On English L2 Learners' Individual Writing Development, Gina Christina Caruso

Dissertations and Theses

Although the benefits of group and pair work in the second language (L2) classroom have been extensively studied, most documented research has focused on the use of oral tasks and spoken interaction between learners. Recently however, researchers have begun to investigate the advantages of collaboration on written work. More specifically, with the advancements in computer technology and web-based collaborative platforms like wikis, there has been a growing awareness of the educational possibilities of wikis to enhance L2 writing instruction. This study followed a pretest/posttest repeated measures design to investigate the impact and students' perceptions of wiki-based collaborative writing activities on …

The Responsibility To Protect And International Law: Moral, Legal And Practical Perspectives On Kosovo, Libya, And Syria, William R. Blackford

Dissertations and Theses

Humanitarian intervention has long been a secondary or tertiary concern in a security driven international system. Since NATO's intervention during the Kosovo crisis in 1999 there have been significant developments in both the language and form of humanitarian intervention as a matter of international law. The events in Kosovo sparked debate about how to handle humanitarian crisis in the future and thus humanitarian intervention evolved into a redefinition of sovereignty as responsibility and the Responsibility to Protect. The Responsibility to Protect has had a number of opportunities to continue to evolve and assert itself in an international legal context throughout …

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

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 Music-Related Concepts To Teach High School Math, Vytas Nagisetty

Dissertations and Theses

The purpose of this research was to test a strategy which uses music-related concepts to teach math. A quasi-experimental study of two high school remedial geometry sections was conducted during a review lesson of ratio, proportion, and cross multiplication. A pretest was given to both groups. Then, Group A received normal textbook instruction while Group B received the treatment, Get the Math in Music, which is an online activity involving proportional reasoning in a music-related context. Afterwards, a posttest was given to both groups. Pretest and posttest scores were used to compare gains in subject knowledge between the groups. Then …

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 …

Designing The Plane While Flying It: A Case Study On Nursing Faculty Development During Academic Electronic Health Records Integration In A Small Liberal Arts College, Karen Elizabeth Maxwell

Dissertations and Theses

The expectation of graduating nurses today is to be knowledgeable and responsive to rapidly changing technology in the health care environment. Although federal mandates, Institute of Medicine (IOM) recommendations, and nursing program accreditation initiatives are pushing an "informatics" healthcare agenda by promoting the implementation of electronic health record (EHR) systems by 2014 in all healthcare facilities, very few US nursing schools provide students with access and training in, EHR systems. In addition, nursing faculty may not have a clear understanding of healthcare informatics; the use of information and technology to communicate, manage knowledge, mitigate error, and support decision-making. Nursing education …

Assessment Of Similarity In Chemically Complex Samples, Jessica Elise Brown

Dissertations and Theses

Concern within the public health community is mounting regarding what some deem as "candy-flavored tobacco". A recent study by King et al. (2014) found that >40% of middle and high school student smokers use flavored cigarettes or flavored little cigars. This study investigated the validity of the "candy-flavored tobacco" designation by comparing flavor profiles of 18 flavored tobacco products with 15 candy and Kool-Aid products using gas chromatography mass spectrometry (GC/MS). Significant compositional overlap was found; nearly 75% of the compounds detected were present in at least one flavored tobacco and one candy or Kool-Aid product. Benzaldehyde and or benzyl …

Gender And Prescription Painkiller Misuse: Findings From The 2011 National Survey On Drug Use And Health, Robin Jo Clough

Dissertations and Theses

This study examines the effects of gender and social bonds on the experience of prescription painkiller misuse for men and women. The theoretical framework for the project is Travis Hirschi's social control theory (1969), and the social bond elements of attachment, commitment, involvement, and belief, which emphasizes the importance of these bonds in creating a "stake in conformity" for the individual, leading to acceptance of social norms and desistence from deviance. This theory, however, is relatively silent with regard to gender differences and was developed to examine delinquency in an all male sample of adolescents. The elements of this theory …

Emerging Lexical Organization From Intentional Vocabulary Learning, Adam Jones

Dissertations and Theses

The role that vocabulary learning plays in second language acquisition has been receiving increased attention from both teachers and researchers. However, there is still much that is not known about the processes through which new words become functioning components of the mental lexicon. This study used a word association test (WAT) to investigate how new words are initially integrated into the lexicon immediately after being studied for the first time. This initial lexical organization of new words was compared with the existing lexical organization of well-known items. In addition, this study investigated how sentence writing, thought to encourage deeper levels …

Cross-Cutting Concerns: The Varying Effects Of Partisan Cues In The Context Of Social Networks, Benjamin King Smith

Dissertations and Theses

The theory of motivated reasoning predicts that partisan cues in the media will affect political attitudes, by encouraging individuals to align their views with those of their party's elites. The effect has primarily been tested by looking at issues which have pre-established partisan positions (e.g. immigration reform, gay rights, etc.). This study looks at the effects of partisan cues in the media on attitudes toward a non-partisan issue, the NSA's collection of American's meta-data. Additionally, the study extends research on partisan cues by exploring the moderating role of an individual's political communication network and, specifically, exposure to cross-cutting political communication. …

Investigating The Link Between Surface Water And Groundwater In The Tule Lake Subbasin, Oregon And California, Esther Maria Pischel

Dissertations and Theses

Water allocation in the upper Klamath Basin of Oregon and California has been challenging. Irrigators have increasingly turned to groundwater to make up for surface water shortages because of shifts in allocation toward in-stream flows for Endangered Species Act listed fishes. The largest increase in groundwater pumping has been in and around the Bureau of Reclamation's Klamath Irrigation Project, which includes the Tule Lake subbasin in the southern part of the upper Klamath Basin. Previous groundwater flow model simulations indicate that water level declines from pumping may result in decreased flow to agricultural drains in the Tule Lake subbasin. Agricultural …

Determinants Of Recent Mover Non-Work Travel Mode Choice, Arlie Steven Adkins

Dissertations and Theses

Active transportation modes of walking and bicycling have the potential to help mitigate environmental and health concerns ranging from growing greenhouse gas emissions to increasing rates of obesity. This dissertation investigates how new movers make decisions about active transportation, particularly non-work utilitarian walking, in the context of a new home and neighborhood. New movers are an important, yet often overlooked, population in travel behavior research because they provide an opportunity to observe behavior adoption in new contexts, but also because the roughly one-in-ten Americans who move each year are more likely to consider changes to daily routines, including travel behavior, …

Synthesizing The Vertical And The Horizontal: A World-Ecological Analysis Of 'The Industrial Revolution', Part I, Christopher R. Cox

Dissertations and Theses

'The Industrial Revolution' is simultaneously one of the most under-examined and overly-simplified concepts in all of social science. One of the ways it is highly under-examined is in the arena of the ecological, particularly through the lens of critical world-history. This paper attempts to analyze the phenomenon through the lens of the world-ecology synthesis, in three distinct phases: First, the history of the conceptualization of the Industrial Revolution is examined at length, paying special attention to the knowledge foundations that determine these conceptualizations. Secondly, I sift out what I believe is the dominant model throughout most of modern …

The Impact Of The Tax Revolt And School Reform On Oregon Schools During The 1990s, Beth Cookler

Dissertations and Theses

When Oregon voters passed the property tax limitation initiative, Measure 5, and the state legislature enacted school reform under the Oregon Educational Act for the 21st Century during the 1990-91 school year, the trajectory of public schooling in the state changed significantly. After Oregon's tax revolt, the state legislature also enacted legislation that equalized school funding throughout the state. The combination of equalization and the Measure 5 step-down to the $5 per $1000 tax limitation led to a decrease in statewide school funding over the decade. Many wealthy urban districts experienced years of budget cuts, while rural districts received additional …

Social Networks Of Intimate Partner Violence Perpetrators, Wendy Elaine Viola

Dissertations and Theses

Empirical research in the areas of substance abuse (Beattie & Longabaugh, 1997; Beattie & Longabaugh, 1999; Falkin & Strauss, 2002; Gordon & Zrull, 1991; Humphreys & Noke, 1997; Mohr et al., 2001; Zywiak, Longabaugh & Wirtz, 2002) and general antisocial behavior (Browning, 2002; Capaldi, Dishion, Stoolmiller & Yoerger, 2001; Dishion, Patterson & Griesler, 1994) and a theoretical model of sexual assault perpetration (DeKeseredy & Schwartz, 1993; DeKeseredy, 1990a; DeKeseredy, 1988; Schwartz & DeKeseredy, 1997) highlight the role of peer groups' attitudes and behaviors in shaping those of their members. Intimate partner violence (IPV) among men's parents (Arriaga & Foshee, 2004; …

Understanding Male Nursing Student Perceptions Of The Influence Of Gender: A Qualitative Case Study Approach Of Students, Faculty, And Administration In A Pacific Northwest Nursing Program, Jennifer Anne Anderson

Dissertations and Theses

In contemporary American society, the nursing profession is predominantly made up of white women. Currently, males make up only 6.8 percent of the three million nursing professionals in the U.S. and they are considered gender minorities within the nursing profession and within nursing education. As gender minorities, male students are identified as experiencing nursing programs and the practice of nursing differently than their female counterparts. The purpose of this single instrumental, within site case study was to explore the learning environment for male nursing students and to investigate the nature of the interactions between nursing faculty and male undergraduate students …

Racism, Heterosexism, Depression, And Hiv Risk Behaviors Of Native Men Who Have Sex With Men: Findings From The Honor Project, Matthew Alan Town

Dissertations and Theses

Racial minority men who have sex with men (MSM) experience greater levels of discrimination and higher rates of HIV infection. However, little is known about the associations between racial and heterosexist discrimination and HIV risk behavior. Further, little is known about the mechanisms of the association between racial and heterosexist discrimination and HIV risk behavior. There is some evidence to suggest that depression may be a mechanism that mediates the relationship between racial and heterosexist discrimination and HIV risk behavior. Thus, one purpose of this study was to investigate the extent to which discrimination based on both race and sexual …

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 …

Benevolent Racism? : The Impact Of Race And Sexual Subtype On Ambivalent Sexism, Jean Marie Mcmahon

Dissertations and Theses

How does a woman's race influence perceptions of her sexual behavior? This study investigated how race and sexual behavior intersect within an ambivalent sexism framework. Benevolent sexism characterizes women as pure and defenseless, which contrasts with the cultural stereotype of Black women as aggressive and hypersexual. Gender and racial stereotypes may combine to produce different outcomes for women who behave according to negative (promiscuous) or positive (chaste) sexual subtypes. According to shifting standards theory, evaluations and treatment of these women should vary depending on whether the measured behavior is non-zero sum (limitless) or zero sum (finite). To test this hypothesis, …

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, …

Predicting Bicyclist Comfort In Protected Bike Lanes, Nicholas Mark-Andrew Foster

Dissertations and Theses

Long popular in northern Europe, protected bike lanes, also known as "cycle tracks" or "separated bike lanes," are seeing increased interest in the United States. One of the primary benefits of protected bike lanes is that they may provide a higher level of comfort than a standard bike lane that is only delineated by an inches-wide painted stripe. Several methods exist for quantifying the quality of service provided by a roadway for a bicyclist; however, many of these models do not consider protected bike lanes and of those that do, none are based on empirical data from the US. This …

Optical Properties Of Nanostructured Dielectric Coatings, Brandon Giatti

Dissertations and Theses

Solar cells have extrinsic losses from a variety of sources which can be minimized by optimization of the design and fabrication processes. Reflection from the front surface is one such loss mechanism and has been managed in the past with the usage of planar antireflection coatings. While effective, these coatings are each limited to a single wavelength of light and do not account for varying incident angles of the incoming light source. Three-dimensional nanostructures have shown the ability to inhibit reflection for differing wavelengths and angles of incidence. Nanocones were modeled and show a broadband, multi-angled reflectance decrease due to …
