Demographic Analysis Of The Healthcare, Manufacturing, And Skilled Trades Industries, Elizabeth Morehead, Sheila A. Martin

Institute of Metropolitan Studies Publications

While the American economy has been characterized by increasing labor-market polarization over the past decade, recent growth in mid-wage, mid-skill jobs holds promise for workers looking for an opportunity to earn a self-sufficient wage.

By July of this year, the economy had added over 900,000 middle-income positions, matching the pace of growth in high-wage fi elds, and outpacing growth in low-wage occupations. Many of these mid-wage and mid-skill jobs can be found in healthcare, production, and the skilled trades, specifi cally construction and extraction, and installation, maintenance, and repair.

Many of these jobs off er an opportunity to earn higher …

Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings

Geography Masters Research Papers

The purpose of this paper is to examine the literature from scientific and governmental entities that describes the problems with elevated stream temperatures in the Tualatin basin, the actions being taken to resolve those problems, and to assess whether these actions are meeting the goal of improving salmonid habitat in the basin. Elevated stream temperatures are considered a pollutant under the US Clean Water Act (Clean Water Act 1972, as amended) because increased stream temperatures can be harmful to native aquatic biota, particularly salmonid fish species that have evolved to use cold water (IMST 2004).

Development Of The Idaho Statewide Travel Demand Model Trip Matrices Using Cell Phone Od Data And Origin Destination Matrix Estimation, Ben Stabler

PSU Transportation Seminars

As part of the initial phase of development for the Idaho Statewide Travel Demand Model, Parsons Brinckerhoff developed a base year auto and truck trip matrix using AirSage cell phone OD data, a statewide network in Cube, traffic counts, and origin-destination matrix estimation (ODME) procedures. To begin, the 4000+ statewide zone system was aggregated into a 700 super zone system for collecting the cell phone OD data. Next, the cell phone data was collected for the month of September 2013 for the following market segments: Average weekday resident HBW, HBO, NHB, and visitor NHB trips. The cell phone trips were …

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 …

Afro-Ecuadorian Educational Movement: Racial Oppression, Its Origins And Oral Tradition, Ethan Johnson

Black Studies Faculty Publications and Presentations

In this paper, three objectives are presented, first, to describe the socio-historical context of Afro-Ecuadorians generally and specifically related to education. Here, it is demonstrated how colonial and nation building practices and processes have attempted to silence and make absent the contributions people of African descent have made to development of the nation. Second, the Afro-Ecuadorian social movement is considered within the local, regional and global socio-historical context, and it is argued that the Afro-Ecuadorian Etnoeducación is part of a continuous struggle for freedom and inclusion in the nation as full citizens. The third area of analysis focuses on one …

Regional Water Providers Consortium Population, Housing Unit, And Household Forecasts 2014 To 2045, Charles Rynerson, Kevin Christopher Rancik

Publications, Reports and Presentations

Water providers have an ongoing need for estimates and forecasts of the total population and the number of housing units and households within their service areas. While some of the water providers within Clackamas, Multnomah, and Washington counties have obtained this information periodically on an individual basis, a complete and systematic set of estimates and forecasts for all members of the Regional Water Providers Consortium has not been prepared for nearly 10 years. The Portland Water Bureau (PWB), on behalf of the Regional Water Providers Consortium, requested that the Portland State University Population Research Center (PRC) update service area boundaries …

Gps Constraints On The Mw = 7.5 Ometepec Earthquake Sequence, Southern Mexico: Coseismic And Post-Seismic Deformation, Shannon E. Graham, Charles Demets, Enrique Cabral-Cano, Vladimir Kostoglodov, Andrea Walpersdorf, Nathalie Cotte, Michael Brudzinski, Robert Mccaffrey, Luis Salazar-Tlaczani

Geology Faculty Publications and Presentations

We use continuous GPS measurements from 31 stations in southernMexico to model coseismic slip and post-seismic deformation from the 2012 March 20 Mw = 7.5 Ometepec earthquake, the first large thrust earthquake to occur below central Mexico during the modern GPS era. Coseismic offsets ranging from ∼280 mm near the epicentre to 5 mm or less at sites far from the epicentre are fit best by a rupture focused between ∼15 and 35 km depth, consistent with an independent seismological estimate. The corresponding geodetic moment of 1.4 × 10²⁰ N·m is within 10 per cent of two independent seismic …

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 …

Synthesis Before The Proto-Niger-Congo Inflectional Verb: Evidence From The Peripheral South Atlantic Languages, George Tucker Childs

Applied Linguistics Faculty Publications and Presentations

This paper contributes to the understanding of Proto-Niger-Congo (PNC) verb structure. It supports the contention in Nurse 2007 that PNC verbs were likely more analytical than synthetic in nature. It does so by illustrating several paths of grammaticalization (and cliticization), in a set of several far-west Atlantic languages, geographically distant from the Niger-Congo core.

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 …

Predicted Effects Of Gypsy Moth Defoliation And Climate Change On Forest Carbon Dynamics In The New Jersey Pine Barrens, Alec M. Kretchun, Robert M. Scheller, Melissa S. Lucash, Kenneth L. Clark, John Hom, Steve Van Tuyl

Environmental Science and Management Faculty Publications and Presentations

Disturbance regimes within temperate forests can significantly impact carbon cycling. Additionally, projected climate change in combination with multiple, interacting disturbance effects may disrupt the capacity of forests to act as carbon sinks at large spatial and temporal scales. We used a spatially explicit forest succession and disturbance model, LANDIS-II, to model the effects of climate change, gypsy moth (Lymantria dispar L.) defoliation, and wildfire on the C dynamics of the forests of the New Jersey Pine Barrens over the next century. Climate scenarios were simulated using current climate conditions (baseline), as well as a high emissions scenario (HadCM3 A2 …

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 …

Empiric Deworming And Cd4 Count Recovery In Hiv-Infected Ugandans Initiating Antiretroviral Therapy, Alexander J. Lankowski, Alexander C. Tsai, Michael Kanyesigye, Mwebesa B. Bwana, Jessica E. Haberer, Megan Wenger, Jeffrey N. Martin, David Bangsberg, Peter W. Hunt, Mark J. Siedner

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: There is conflicting evidence on the immunologic benefit of treating helminth co-infections (‘‘deworming’’) in HIV-infected individuals. Several studies have documented reduced viral load and increased CD4 count in antiretroviral therapy (ART) naive individuals after deworming. However, there are a lack of data on the effect of deworming therapy on CD4 count recovery among HIV-infected persons taking ART.

Methodology/Principal Findings: To estimate the association between empiric deworming therapy and CD4 count after ART initiation, we performed a retrospective observational study among HIV-infected adults on ART at a publicly operated HIV clinic in southwestern Uganda. Subjects were assigned as having received …

Regulations Of E-Bikes In North America, John Macarthur, Nicholas Kobel

TREC Final Reports

Throughout the world, the electric bicycle (e-bike) industry is growing very quickly. The North American market has been somewhat slow to adopt this technology, which is still considered to be in the “early adopter” phase (Rose & Dill, 2011; Rose, 2011), but in recent years, this has begun to change. But as e-bike numbers increase, so too will potential conflicts (actual or perceived) with other vehicles and non-motorized devices, bicycles and pedestrians, causing policy questions to arise. Indeed, conflicting user groups are petitioning state legislatures and local governments for permission to operate legally on roadways and paths or to ban …

How It Got Here: Teaching 'Format As Process' In An Era Of Web-Scale Discovery, Kevin Seeber

Library Instruction West 2014

What has the growth in web-scale discovery services meant for information literacy instruction? And what kind of threshold concepts do students need to grasp before they can use these tools effectively? This presentation addresses the concept of “format as process,” which emphasizes that evaluating information should focus on how it was produced, rather than how it is accessed. As students navigate discovery tools which combine a wide variety of source types into a single results list, their understanding of this concept is vital to evaluating resources and selecting those which are the most relevant. Learn about how “format as process” …

Business Owner Outreach: Creekside District Master Plan, Meg Merrick, Brenda Martin

Institute of Metropolitan Studies Publications

In April 2011, the City of Beaverton adopted its Civic Plan Central City Strategy (“the Civic Plan”). The Civic Plan provides a new understanding of the Central City. One of the Civic Plan’s most important strategic goals is the transformation of the Creekside District (an underutilized 50-acre site situated at the heart of the Central City) into a vibrant, sustainable, mixed-use community. The Creekside District master planning effort (that is supported by a HUD Community Challenge Grant) will produce a development program that integrates: suitable and affordable housing for existing and future populations; increased efficiency and connectivity of existing public …

Evidence-Based Decision Making In Coastal Oregon: Increasing The Effectiveness Of Policy And Management Decisions, Kaitlin Goldsmith

Environmental Science and Management Professional Master's Project Reports

Changing climatic conditions, demographics, and land uses are projected to alter the provisioning of ecosystem services in estuarine, coastal and nearshore marine ecosystems, necessitating mitigation and adaptation policies and management. The current paradigm of siloed research efforts occurring in parallel to, rather than in collaboration with, decision-makers will be insufficient for the rapid responses required to adapt to and mitigate for projected changing conditions in coastal areas. Here, I suggest a different paradigm: one where research begins by engaging decision-makers in the identification of priority research needs (biophysical, economic, and social), and in which researchers analyze and present data in …

Accessibility-Based Transportation Planning: Literature And Applications For Shrinking Cities, Joanna Ganning

TREC Final Reports

For 15 years, scholars have claimed that accessibility-based transportation planning was at the brink of becoming a new paradigm, and yet this hope remains unrealized. Its implementation may lag due to vague definitions when compared to mobility, or because those who would benefit from accessibility-based planning lack political power to rally its support. Possibly, the lag in implementation reflects the missing linkages between theory and application for many contexts. This literature review synthesizes knowledge regarding the applications for accessibility-based transportation planning for shrinking cities along the themes of environmental, social, and economic sustainability. While residents in shrinking cities might especially …

Assessing Transit Fare Equity In Utah Using A Geographic Information System, Steven Farber, Keith Batholomew, Xiao Li, Antonio Paez, Khandker M. Nurul Habib

TREC Final Reports

The goal of this study is to develop and apply a new method for assessing social equity impacts of distance-based public transit fares. Shifting to a distance-based fare structure can disproportionately favor or penalize different subgroups of a population based on variations in settlement patterns, travel needs, and most importantly, transit use. According to federal law, such disparities must be evaluated by the transit agency, but the area-based techniques identified by the Federal Transit Authority for assessing discrimination fail to account for disparities in distances travelled by transit users. This means that transit agencies currently lack guidelines for assessing the …

A Survey Of Urban Agriculture Organizations And Businesses In The Us And Canada: Preliminary Results, Nathan Mcclintock, Mike Simpson

Urban Studies and Planning Faculty Publications and Presentations

This report summarizes the results of an online survey, conducted during February and March 2013, of 251 groups involved with urban agriculture (UA) projects in approximately 84 cities in the US and Canada. This is only a preliminary report. As such, we present descriptive statistics rather than a interpretive analysis of the survey responses. Furthermore, it is important to recognize that these results are not necessarily representative of all urban agriculture businesses and organizations across North America. Nevertheless, these results point to certain trends and patterns that offer rich opportunities for further inquiry.

Our preliminary results reveal that the UA …
