Building Resources At Home And At Work: Day-Level Relationships Between Job Crafting, Recovery Experiences, And Work Engagement, Allison Marie Ellis

Dissertations and Theses

Work engagement is an increasingly popular construct in organizational and occupational health psychology. However, despite substantial advances in our understanding of work engagement at the between-person level, scholars have argued for increased investigation into what drives engagement on a daily level for individual employees. In the current study, a within-person, day-level design was employed to examine the relationships between nonwork mastery experiences, job crafting behaviors, and daily work engagement. Drawing on Conservation of Resources (Hobfoll, 1989) theory, nonwork mastery experiences and job crafting were operationalized as employee-driven, resource-building strategies that assist employees in generating important psychological and job resources that …

Dynamic Job Satisfaction Shifts: Implications For Manager Behavior And Crossover To Employees, David Ellis Caughlin

Dissertations and Theses

In this dissertation, I investigated job satisfaction from a dynamic perspective. Specifically, I integrated the momentum model of job satisfaction with the affective shift model and crossover theory in an effort to move beyond traditional, static conceptions of job satisfaction and other constructs. Recent research and theoretical development has focused on the meaning of job satisfaction change for workers and how such change impacts their decisions to leave an organization. To extend this line of inquiry, I posited hypotheses pertaining to: (a) job satisfaction change with respect to positive work behavior (i.e., organizational citizenship behavior, family-supportive supervisor behavior); (b) the …

The Response Of Zooplankton Communities In Montane Lakes Of Different Fish Stocking Histories To Atmospheric Nitrogen Deposition Simulations, Jeffrey Thomas Brittain

Dissertations and Theses

Freshwater ecosystems are subject to a wide variety of stressors, which can have complex interactions and result in ecological surprises. Non-native fish introductions have drastically reduced the number of naturally fishless lakes and have resulted in cascading food web repercussions in aquatic and terrestrial habitats. Additional anthropogenic influences that result from increases in global airborne emissions also threaten wildlife habitat. Atmospheric nitrogen deposition has been recognized as an anthropogenic contributor to acidification and eutrophication of wilderness ecosystems. Planktonic communities have shown declines in response to predation and shifts in composition as a result of nutrient inputs and acidification, both of …

Behavior Of Reinforced Concrete Beams Retrofitted In Flexure Using Cfrp-Nsm Technique, Salam Al-Obaidi

Dissertations and Theses

A variety of retrofitting methods are used to upgrade existing structures. For example, steel plates and Fiber Reinforced Polymer (FRP) jackets are externally bonded to members to increase their capacity in flexure and shear. However, due to the issue of corrosion these strengthening systems may lose their efficiency with time. FRP materials have been used to strengthen many structural components of different shapes and types. FRP jackets, FRP Strips, and FRP rods have commonly been used to rehabilitate existing structural components. The many advantages of using FRP as strengthening materials have made this material an attractive alternative: advantages such as …

Challenges, Experiences, And Future Directions Of Senior Centers Serving The Portland Metropolitan Area, Melissa Lynn Cannon

Dissertations and Theses

A growing body of research emphasizes the development of an understanding of the relationship between older adults and their physical and social environments (Wahl & Weisman, 2003). Researchers, planners, policymakers, and community residents have been increasingly interested in shaping urban environments as places that foster active aging and independence among older adults. Senior centers have served a critical role in their communities as focal points for older adults, as individuals or in groups, to participate in services and activities that support their independence and encourage their involvement in and with the community (NCOA, 1979). The aging of the population and …

Sound Effects: Age, Gender, And Sound Symbolism In American English, Timothy Allen Krause

Dissertations and Theses

This mixed-method study investigated the correlation of sound symbolic associations with age and gender by analyzing data from a national survey of 292 American English speakers. Subjects used 10 semantic differential scales to rate six artificial brand names that targeted five phonemes. Subjects also described the potential products they imagined these artificial brand names to represent. Quantitative analysis alone provided insufficient evidence to conclude that age or gender affect sound symbolism in American English. While 26 out of 60 scales showed a monotonic shift among the means of the three age groups, only three were statistically significant. The evidence of …

Untitled, Alexander Scott Dannemiller

Dissertations and Theses

Deeply concerned with body politics, sexual slavery, identity, and technology, this work takes a serious and brutally honest route through the close perspectives of those living it moment by moment. With influences from science fiction, horror, weird, and literary fiction, the untitled novel blends genres for a disturbing account. This novel also plays with constraints in the spirit of many constraint-based writing movements, without the inclusion of names, few identifying markers, and in publication the removal of title, chapter numbers, page numbers, and author name.

Effects Of Selective Logging And Roads On Instream Fine Sediments And Macroinvertebrate Assemblages In The Clackamas Basin, Oregon, Paula Elizabeth Hood

Dissertations and Theses

Logging and associated skid trails, haul routes, and roads can have significant impacts on the magnitude and timing of sediments in streams in forested watersheds. Loss of vegetation, soil compaction, use of heavy logging equipment, and alteration of natural hydrologic patterns within the watershed can increase landslide rates, create erosion, and generate fine sediments. Selective logging, also called thinning, is a logging practice that leaves some trees within sale units unharvested. The ecological impacts of thinning on stream ecosystems are not fully understood and need further study. My hypothesis was that macroinvertebrate assemblages would be different in streams in non-reference …

The Scholarship Of Student Affairs Professionals: Effective Writing Strategies And Scholarly Identity Formation Explored Through A Coaching Model, Lisa Janie Hatfield

Dissertations and Theses

Student affairs professionals work directly with university students in various programs that provide services to these students. From these experiences, they collect daily valuable insights about how to serve students successfully. Yet, in general, they are not publishing about their work even though dissemination of such knowledge through publication could positively impact programs and services across many institutions. My dissertation explored what happens when mid-level student affairs professionals pursue scholarly writing during a structured program intended to help participants produce manuscripts for publication. In working with five professionals in student services at a large urban institution in the Pacific Northwest …

Dissertations and Theses

This thesis tells the stories of five Oregon women who transcended the customary roles of their era. Active during the waning years of the nineteenth century and the beginning of the twentieth century, each woman made a difference in the world around them. Their stories have either not been told or just given a passing glance. These tales are important because they inform us about our society on the cusp of the twentieth century.

Hattie Crawford Redmond was the daughter of a freed slave who devoted herself to the fight for women's suffrage. Minnie Mossman Hill was the first woman …

The Impact Of Communication Impairments On The Social Relationships Of Older Adults, Andrew Demetrius Palmer

Dissertations and Theses

Communication forms the foundation of social interaction. For older adults, however, there is known to be an increased risk of developing conditions that interfere with the ability to communicate. These conditions may occur for a variety of reasons, including age-related changes in physical or sensory functioning, injury, and disease. It is estimated that 55% of all Medicare beneficiaries have a communication impairment of some kind. Social contact is known to be vital for older adults' mental and physical health but, because communication impairments often co-occur with other types of disability, it is difficult to generalize about the relative impact of …

Evaluating The Effects Of A Congestion And Weather Responsive Advisory Variable Speed Limit System In Portland, Oregon, Matthew Blake Downey

Dissertations and Theses

Safety and congestion are ever present and increasingly severe transportation problems in urban areas throughout the nation and world. These phenomena can have wide-ranging consequences relating to safety, the economy, and the environment. Adverse weather conditions represent another significant challenge to safety and mobility on highways. Oregon is not immune from either of these global issues. Oregon Route (OR) 217, to the southwest of the downtown Portland, is one of the worst freeways for congestion in the state and is also subject to the Pacific Northwest's frequently inclement and unpredictable climate. High crash rates, severe recurrent bottlenecks and highly unreliable …

Combining Systems Methodologies To Reduce Allergen-Related Food Recalls, Jill Marie Sweney

Dissertations and Theses

The risk of poor food safety is a major focus for managers in the food manufacturing industry. Despite industry-led and regulatory efforts to improve the overall food safety of US packaged consumer foods, product recalls and market withdrawals are increasing. This is especially true for the most frequent cause for food recall: the undeclared allergen. With industry trends leaning toward adoption of third-party food safety management certifications, a popular food safety code from the Safe Quality Foods Institute is evaluated using Systems Analysis. Three changes to the food safety code are proposed to address three of the top causes for …

Findings from the study support that Socratic questioning can …

The Effects Of Urban Containment Policies On Commuting Patterns, Sung Moon Kwon

Dissertations and Theses

During the past several decades, most U.S. metropolitan areas have experienced strong suburbanization of housing and jobs (i.e., urban sprawl). The sprawl that arises from urban growth has become a big issue in many metropolitan areas in the U.S. In response, there has been increased interest in urban containment policies. There are contrasting views (planning-oriented vs. market-oriented) of urban sprawl and urban containment policies. Planning-oriented scholars asserted the problems of 'geographic sprawl (GS)' and the positive effects of urban containment polices, while market-oriented scholars asserted the problems of 'economic sprawl (ES)' and the negative or negligible effects of urban containment …

Developing Key Sustainability Competencies Through Real-World Learning Experiences: Evaluating Community Environmental Services, Erin Lorene Anderson

Dissertations and Theses

This study focuses on sustainability in higher education and the competencies essential to address sustainability issues. Because sustainability issues are complex, "wicked", and dynamic, sustainability education programs need to reflect the interdisciplinary and collaborative nature of the field. Graduates who are competent in sustainability research and problem solving will have the knowledge, skills, and attitude necessary to analyze a sustainability problem systemically and comprehensively, then will construct and implement interventions to reach optimal sustainability solutions. To prepare graduates, sustainability education programs should facilitate the development of key sustainability competencies (Wiek, Withycombe, & Redman, 2011). Such programs provide an interdisciplinary approach …

Measuring The Effect Of Vegetated Roofs On The Performance Of Photovoltaic Panels In Combined Systems, Hamid Hawi Kadham Ogaili

Dissertations and Theses

Recent studies suggest that integration of photovoltaic panels with green roofs may improve the performance of both. While vegetation may provide a benefit by reducing the net radiation load on the underside of the photovoltaic (PV) panels, it may also affect convective cooling of panels, and consequently, panel efficiency. Both effects likely diminish with the height of the PV panel above the roof, although placing PV panels too close to the vegetation increases the risk of the plants growing over the edges of, and shading the PV panel. There is a gap in the literature with respect to evaluating these …

Modeling The Optical Response To A Near-Field Probe Tip From A Generalized Multilayer Thin Film, A.J. Lawrence

Dissertations and Theses

The contrast mechanism in Kerr imaging is the apparent angle through which the plane of polarization is rotated upon reflection from a magnetic surface. This can be calculated for a well characterized surface given the polarization state of the incident light. As in traditional optical microscopy, the spatial resolution is limited by diffraction to roughly half the wavelength of the illumination light.

The diffraction limit can be circumvented through the use of near-field scanning optical microscopy, in which the illumination source is an evanescent field at the tip of a tapered optical fiber. A novel probe design for near-field optical …

Exploring The Developmental Dynamics Of Motivational Resilience Over The Transition To Middle School, Jennifer Rose Pitzer

Dissertations and Theses

In recent years students' academic engagement has gained increasing favor as a necessary component of authentic learning experiences. However, less research has focused on what students do when they run into everyday problems in school that allows them to return (or not) to a state of ongoing engagement. Expanding on these ideas, this project explores students' motivational resilience in school, that is, the dynamic interactions among their ongoing engagement, emotional reactivity, academic coping, and re-engagement after encounters with difficulties and setbacks in school. Grounded in an established motivational model based on Deci & Ryan's (1985) self-determination theory, and building on …

Dissertations and Theses

As the demand for microprocessors is increasing with more and more consumers using integrated circuits in their daily life, the demand on the industry is increasing to ramp up production.

In order to speed up the manufacturing processes, new and novel approaches are trying to change certain aspects of it. Microwaves have been tried as an alternative to conventional ovens in the curing of the polymers used as underfills and encapsulants in integrated circuits packages. Microwaves however being electromagnetic waves have non uniform energy distribution in different settings, causing burning or incomplete cure of polymers.

In this study, we compare …

Landforms Along The Lower Columbia River And The Influence Of Humans, Charles Matthew Cannon

Dissertations and Theses

River systems, such as the Columbia River in the Pacific Northwest, USA have been influenced by human activities, resulting in changes to the physical processes that drive landform evolution. This work describes an inventory of landforms along the Columbia River estuary between the Pacific Ocean and Bonneville Dam in Oregon and Washington. Groupings of landforms are assigned to formative process regimes that are used to assess historical changes to floodplain features. The estuary was historically a complex system of channels with a floodplain dominated by extensive tidal wetlands in the lower reaches and backswamp lakes and wetlands in upper reaches. …

A Metal-Free Approach To Biaryl Compounds: Carbon-Carbon Bond Formation From Diaryliodonium Salts And Aryl Triolborates, Kuruppu Lilanthi Jayatissa

Dissertations and Theses

Biaryl moieties are important structural motifs in many industries, including pharmaceutical, agrochemical, energy and technology. The development of novel and efficient methods to synthesize these carbon-carbon bonds is at the forefront of synthetic methodology. Since Ullmann’s first report of stoichiometric Cu-mediated homo-coupling of aryl halides, there has been a dramatic evolution in transition metal catalyzed biaryl cross-coupling reactions.

Our work focuses on the discovery and development of an unprecedented reagent combination for metal-free cross-coupling. It is hypothesized that direct carbon-carbon bond formation occurs via a triaryl-λ³-iodane and that electrophile/nucleophile pairing is critical for success in the reaction. Proof-of-concept …

Impact Of A State Evidence-Based Practice Legislative Mandate On County Practice Implementation Patterns And Inpatient Behavioral Health Discharge, Carl William Foreman

Dissertations and Theses

Evidence-based practices and comparative effectiveness research are salient topics in public policy. Empirical validation of agency operating processes provides agencies and policy-makers the opportunity to address uncertainty surrounding effectiveness. While this is an increasingly accepted rational approach to public policy, the exact mechanism for how this operates is less known. In order to evaluate several theoretical assumptions and normative rational expectations inherent in this approach, the implementation of a state legislative mandate stating policy expectations for behavioral health evidence-based practices is assessed. This study sought to assess whether implementation patterns and associated outcomes reflect "rational mechanism" policy expectations. While the …

Rethinking Autism, Communication, And Community Involvement: Exploring Involvement In Online Communities, Communication Preference, Autistic Identity, And Self-Determination, Colleen Anne Kidney

Dissertations and Theses

Autistic individuals experience marginalization and stigmatization, and are often not connected to mainstream services or organizations fostering peer relationships (Boundy, 2008; Jaarsma & Welin, 2012; Robertson, 2010). Therefore, the accomplishments of the online Autistic community in building a community for self-advocacy, peer-support, friendships, and identity development (Brownlow & O'Dell, 2006; Kidney, 2012) are important to recognize, empirically examine, and promote (Blume, 1997a; Davidson, 2008). Utilizing a community-based participatory research approach (CBPR; Israel, Schulz, Parker, & Becker, 1998) the Academic Autistic Spectrum Partnership in Research and Education (AASPIRE; www.aaspire.org) conducted the AASPIRE Internet Use, Community, and Well-Being Study, and collected …

Exploring Dietary Sacrifice In Intimate Relationships For Couples With Celiac Disease, Lindsey Marie Alley

Dissertations and Theses

Prior research on eating behaviors has shown that romantic partners actively merge their dietary preferences throughout the course of a relationship and find significant value in cooking and eating the same foods together at the same times. Yet, little is known regarding the impacts of specific dietary support processes involved in maintaining said communal diet when one partner drastically alters his or her eating patterns. The current study defined dietary sacrifice as a phenomenon within the context of Celiac Disease (CD): a chronic illness that requires strict adherence to the gluten-free diet (GFD). Drawing from existing research on sacrifice within …

Age Determination Of Modern And Archaeological Chinook Salmon (Oncorhynchus Tshawytcha) Using Vertebrae, Anthony Raymond Hofkamp

Dissertations and Theses

Incremental growth rings in X-rays of salmon vertebrae have been used since the 1980s to age Pacific salmon (Oncorhynchus spp.) remains from archaeological sites in the Pacific Northwest. These age estimates, paired with generalized life history patterns, have been used to determine salmon species, season of capture and in turn season of site occupation. This approach relies on a variety of assumptions, the most fundamental of which is that rings represent true years. Archaeologists using vertebral age determination techniques have failed to adequately test this assumption and present their methodologies. This thesis assesses the validity of using incremental …

Bicyclist Compliance At Signalized Intersections, Samson Ray Riley Thompson

Dissertations and Theses

This project examined cyclist red light running behavior using two data sets. Previous studies of cyclist compliance have investigated the tendencies of cyclists to run red lights on the whole by generalizing different maneuvers to their end outcome, running a red light. This project differentiates between the different types of red light running and focuses on the most egregious case, gap acceptance, which is when a cyclist runs a red light by accepting a gap in opposing traffic.

Using video data, a mathematical model of cyclist red light running was developed for gap acceptance. Similar to other studies, this analysis …

Vortex Identification In The Wake Of A Wind Turbine Array, Aleksandr Sergeyevich Aseyev

Dissertations and Theses

Vortex identification techniques are used to analyze the flow structure in a 4 x 3 array of scale model wind turbines. Q-criterion, Δ-criterion, and λ₂-criterion are applied to Particle Image Velocimetry data gathered fore and aft of the last row centerline turbine. Q-criterion and λ₂-criterion provide a clear indication of regions where vortical activity exists while the Δ-criterion does not. Galilean decomposition, Reynolds decomposition, vorticity, and swirling strength are used to further understand the location and behavior of the vortices. The techniques identify and display the high magnitude vortices in high shear zones resulting from the …

Impact Of A Psychology Of Masculinities Course On Women's Attitudes Toward Male Gender Roles, Sylvia Marie Ferguson Kidder

Dissertations and Theses

Individuals are involved in an ongoing construction of gender ideology from two opposite but intertwined directions: they experience pressure to follow gender role norms, and they also participate in the social construction of these norms. An individual's appraisal, positive or negative, of gender roles is called a "gender role attitude." These lie on a continuum from traditional to progressive. Traditional gender role attitudes have been linked to primarily negative outcomes.

This thesis examines attitudes toward--and beliefs about--male gender in women completing an elective course on the psychology of men and masculinities. Study 1 assessed how these students' (N = …
