Gifted Black And Biracial Students At A Predominantly White Gifted School, Clair Elizabeth Pople

Dissertations and Theses

The underrepresentation of gifted Black and Biracial students is a pervasive problem in and of itself, and indicates a much larger struggle of disproportionality of Black and Biracial students who are not called upon or supported in efforts to meet their academic potential. Therefore, an evaluation of the inequity generated by gifted education is warranted. It is true that the majority of gifted programs are often predominantly White. Accordingly, Black and Biracial students who qualify for gifted programs may face unique challenges in their development of racial identity and their socio-emotional health.

Using ethnographic techniques, this case study explored the …

Identity And Investment In The Community Esl Classroom, Jennifer Marie Sacklin

Dissertations and Theses

After Norton Peirce's (1995, Norton, 2000) groundbreaking work in conceptualizing identity as "multiple, changing, and contradictory," many researchers have explored language learners' identities. However, few studies of identity have been conducted within the "overlooked and understudied" (Mathews-Aydinli, 2008) context of adult community ESL (English as a Second Language), and even fewer studies have focused on LESLLA (low-educated second language and literacy acquisition) learners in mainstream community ESL programs.

This thesis, based on a case study of an adult LESLLA learner in a community ESL class, analyzes how this student's identity, the social context of her life, and the classroom space …

Revealing Structural Organization With Liquid Crystal-Based Spectral Imaging Polarimetry, James Campbell Gladish

Dissertations and Theses

Structural organization refers to the particular ordering of scatterers. Probing structural organization by imaging polarized spectral scatter provides insight into the composition of a medium, and can aid in remote sensing, the identification of tissue pathologies, and material characterization and differentiation. The vector nature of polarized light enables it to interact with optical anisotropies within a medium, while the spectral aspect of polarization is sensitive to small-scale structure. However, many polarization studies have limitations, as they provide qualitative image analysis, incomplete anisotropy information, or both. The ability to image the effects of anisotropy and small-scale structure at multiple wavelengths is …

Intrapersonal And Interpersonal Consequences Of Loneliness: Health Behavior, Social Interactions, Self-Disclosure, And Perceived Responsiveness, Sarah Noel Arpin

Dissertations and Theses

As a social species, human beings are driven by an innate desire to belong and are thus motivated to develop and maintain meaningful social relationships. As such, perceiving a lack of belongingness strongly impacts psychological and physiological health and well-being. A common form of perceived relationship deficits is loneliness, a negative-affective experience detrimental to health and well-being over time. Through a series of three manuscripts, this dissertation applies the full-cycle model of social psychological research to explore various affective, behavioral, and cognitive consequences of loneliness. Whereas existing models of loneliness focus on long-lasting or chronic forms of loneliness, these studies …

The Cognitive Development Of Expertise In An Esl Teacher: A Case Study, Lyndsey Roos

Dissertations and Theses

This case study investigated how an English as a Second Language (ESL) teacher's cognition has both changed and stayed constant over a period of eight years and the factors to which the teacher attributes changes or lack of changes. The study followed the teacher over the course of a 10-week period and compared videos of the participant's teaching from eight years ago to her current teaching. Interviews, observations, and stimulated recall were used to investigate development over the eight year span. It was found that the teacher did indicate several areas in which she demonstrated change: Teaching with fluidity, automaticity, …

Training And Application Of Correct Information Unit Analysis To Structured And Unstructured Discourse, Audrey Bretthauer Cohen

Dissertations and Theses

Correct Information Units (CIU) analysis is one of the few measures of discourse that attempts to quantify discourse as a function of communicating information efficiently. Though this analysis is used reliably as a research tool, most studies' apply CIUs to structured discourse tasks and do not specifically describe how raters are trained. If certified clinical speech-language pathologists can likewise reliably apply CIU analysis within clinical settings to unstructured discourse, such as the discourse of people with aphasia (PWA), it may allow clinicians to quantify the information communicated efficiently in clinical populations with discourse deficits. Purpose: The purpose of this study …

Transformational Leadership, Diversity, And Creativity At Work: A Moderated Mediation Model, Aisha Smith Taylor

Dissertations and Theses

Organizational leaders often seek to hire and retain innovative employees as a source of competitive advantage. Both transformational leadership and effectively managed workplace diversity have been theorized and shown to lead to increased employee creative performance at work; however, a full model of the relationships between leadership and the multi-dimensional construct of workplace diversity has not yet been tested. Using a sample of 371 employees in three Chinese high-technology firms matched with 64 supervisors collected at three time points, this study theorized and tested a moderated mediation path model in which transformational leadership and diversity climate were predicted to significantly …

Use Of Role And Power In Parent-Teacher Relationships: Perceptions From The Parent Perspective, Sonja Taylor

Dissertations and Theses

Studies have increasingly shown that more parent involvement leads to higher academic achievement for kids. However, studies have also shown a difference in the ability of parents to effectively further their children's interest based on social class. Middle-class parents are described as being able to activate their cultural and social capital in order to further their interests, while working-class and low-income parents have been described as frustrated and marginalized- lacking the ability to activate their capital in a way that benefits themselves and their children.

The intent of this study is to explore how parents understand their role in the …

Post-Silicon Functional Validation With Virtual Prototypes, Kai Cong

Dissertations and Theses

Post-silicon validation has become a critical stage in the system-on-chip (SoC) development cycle, driven by increasing design complexity, higher level of integration and decreasing time-to-market. According to recent reports, post-silicon validation effort comprises more than 50% of the overall development effort of an 65nm SoC. Though post-silicon validation covers many aspects ranging from electronic properties of hardware to performance and power consumption of whole systems, a central task remains validating functional correctness of both hardware and its integration with software. There are several key challenges to achieving accelerated and low-cost post-silicon functional validation. First, there is only limited silicon observability …

Staying On Script: Sexual Scripts And Sex Education, Elizabeth Carol Hauck

Dissertations and Theses

Existing research suggests that men and women develop differing sexual scripts that influence their behavior, interactions and emotions regarding sex. The objective of this project is to examine the experiences of men and women with formal sex education programs, especially in regards to information about: anatomy and biology, sexual responsibility and risk taking, sexual desire, virginity and abstinence, as well as to explore sources of sex education outside of school. Several studies suggest masculine sexual scripts dictate that men generally construct a more body-focused approach to sex, with an emphasis on competition, aggression and achievement. Conversely, emphasized feminine sexual scripts …

These methods are provided in chapters about integrating state and national education standards in the STEM fields, core academic subject fields, and foreign language teaching, and finally in chapters about the most appropriate and effective pedagogies for successful …

Novel Methods For Learning And Adaptation In Chemical Reaction Networks, Peter Banda

Dissertations and Theses

State-of-the-art biochemical systems for medical applications and chemical computing are application-specific and cannot be re-programmed or trained once fabricated. The implementation of adaptive biochemical systems that would offer flexibility through programmability and autonomous adaptation faces major challenges because of the large number of required chemical species as well as the timing-sensitive feedback loops required for learning. Currently, biochemistry lacks a systems vision on how the user-level programming interface and abstraction with a subsequent translation to chemistry should look like. By developing adaptation in chemistry, we could replace multiple hard-wired systems with a single programmable template that can be (re)trained to …

An Investigation Of The Role Of Alternate Numeration Systems In Preservice Teacher Mathematics Content Courses, Jodi I. Fasteen

Dissertations and Theses

Alternate numeration systems are common in preservice teacher (PST) mathematics curricula, but there is limited research on how to leverage alternate systems to promote the development of mathematical knowledge for teaching. I analyzed the role of alternate numeration systems in three ways. I conducted a thematic analysis of current PST textbooks to consider the role of alternate numeration systems in written curricula. I conducted a teaching experiment to analyze PSTs' mathematical activity as they engaged with a base five task sequence to reinvent an algorithm for multiplication. And I introduced problematizing mathematical contexts as a design heuristic, situating this within …

Hardware/Software Interface Assurance With Conformance Checking, Li Lei

Dissertations and Theses

Hardware/Software (HW/SW) interfaces are pervasive in modern computer systems. Most of HW/SW interfaces are implemented by devices and their device drivers. Unfortunately, HW/SW interfaces are unreliable and insecure due to their intrinsic complexity and error-prone nature. Moreover, assuring HW/SW interface reliability and security is challenging. First, at the post-silicon validation stage, HW/SW integration validation is largely an ad-hoc and time-consuming process. Second, at the system deployment stage, transient hardware failures and malicious attacks make HW/SW interfaces vulnerable even after intensive testing and validation. In this dissertation, we present a comprehensive solution for HW/SW interface assurance over the system life cycle. …

Engineering Professional Development: Elementary Teachers' Self-Efficacy And Sources Of Self-Efficacy, Donna Louise Webb

Dissertations and Theses

Currently, STEM (science, technology, engineering, and mathematics) is a popular buzz word in P -12 education as it represents a means to advance American competitiveness in the global economy. Proponents of the engineering component of STEM advocate additional benefits in teaching engineering, such as its capacity to engage students in collaboration, and to apply critical thinking, systems thinking, negotiation, and communication skills to solve real-life contextual problems. Establishing a strong foundation of engineering knowledge at a young age will provide students with internal motivation as it taps into their curiosity toward how things work, and it also prepares them for …

The Floating Men: Portland And The Hobo Menace, 1890-1915, Marin Elizabeth Aurand

Dissertations and Theses

At the beginning of the twentieth century, transient laborers in Portland, Oregon faced marginalization and exploitation at the hands of the classes that relied on them for their own prosperity. Portland at this time was poised to flourish as a major population and industrial center of the American West. The industries that fueled the city's growth were dependent on cheap and mobile manual labor made available by the expansion of the nation's railroads. As the city prospered and grew, the elite of the city created and promoted an image of Portland as an Eden of material abundance where industriousness and …

Democratizing The City Through The Colonization Of Public Space: A Case Study Of Portland Food Not Bombs, Trent Adam Saari

Dissertations and Theses

The implementation of neoliberal economic and political policies is often touted as a way to increase overall individual well-being and freedom. While these policies may benefit those already wielding economic security and political power, marginalized populations often bear the negative cost associated with such policies. As deregulation and privatization increases, social safety nets and social spending are dramatically reduced. At the local level, liberalization has resulted in increased surveillance and regulation of public space. Organized resistance to global corporatization and increased economic and political marginalization has occurred across the globe. Resisting neoliberalism is complex as the adaptability of the state …

Dissertations and Theses

Shear strength of fiber reinforced concrete beams was studied in this research project. Three types of fibers were examined: hooked-end steel fiber, crimped-steel fiber, and crimped-monofilament polypropylene fibers. The experimental program included five beam specimens. Two of the beams were control specimens in which one was reinforced with minimum shear reinforcement according to ACI 318, while the other one did not have any shear reinforcement. Each one of the other three specimens was reinforced with one of the above mentioned fibers by 1% volumetric ratio. In addition to the beam specimens, three prisms were also made for each type fiber …

Reversible Circuits Synthesis Based On Exor-Sum Of Products Of Exor-Sums, Linh Hoang Tran

Dissertations and Theses

Power dissipation in modern technologies is an important matter and overheating is a severe concern for both manufacturer (impossibility of introducing new and smaller scale technologies and limited temperature range for operating the product) and customer (power supply, which is especially important for mobile systems). One of the main profits that reversible circuit carries is theoretically the zero power dissipation in the sense that it is independent of underlying technology; irreversibility means heat generation. In the other words, reversible circuits may offer a feasible solution in the future that will aid certain reduction of the power loss.

Reversible circuits are …

Assessing Unique Core Values With The Competing Values Framework: The Ccvi Technique For Guiding Organizational Culture Change, Anthony John Santoriello

Dissertations and Theses

Extensive research suggests organizations have unique guiding principles, called core values, which play a central role in strategic decision making, sustaining high-performance cultures, and guiding organizational culture change. Although the Competing Values Framework (CVF) has been widely used to identify a standardized set of core values, it has not been used to identify unique core values at a given organizations. Unique core values help to distinguish organizations and drive market success.

The present research focused on development of a technique to extend the application of the CVF to identify the core values unique to a given organization. The CVF-based Core …

The multi downscaled-scenario products allow us to better assess the uncertainty of the variations of precipitation and temperature in the current and future periods. Joint Probability distribution functions (PDFs), of both the climatic variables, might help better understand the interdependence of the two, and thus in-turn help in accessing the future with confidence. In the present study, we have used multi-modelled statistically downscaled ensemble of precipitation and temperature variables. The dataset used is multi-model ensemble of 10 Global Climate Models (GCMs) downscaled product from CMIP5 daily dataset, using the Bias Correction and Spatial Downscaling (BCSD) technique, generated at Portland State …

Building Social Sustainability From The Ground Up: The Contested Social Dimension Of Sustainability In Neighborhood-Scale Urban Regeneration In Portland, Copenhagen, And Nagoya, Jacklyn Nicole Kohon

Dissertations and Theses

In response to growing social inequality, environmental crises, and economic instability, sustainability discourse has become the dominant "master signifier" for many fields, particularly the field of urban planning. However, in practice many sustainability methods overemphasize technological and economic growth-oriented solutions while underemphasizing the social dimension. The social dimension of sustainability remains a "concept in chaos" drawing little agreement on definitions, domains, and indicators for addressing the social challenges of urban life. In contrast, while the field of public health, with its emphasis on social justice principles, has made significant strides in framing and developing interventions to target the social determinants …

Few studies to date have investigated associations among work, family, and sleep outcomes. The following dissertation includes three studies that attempt to further understanding of such relationships by utilizing data from information technology workers within the Work, Family, and Health Network study. In Study 1, which is published in the Journal of Occupational Health Psychology, associations between work-to-family conflict, family-to-work conflict, family-supportive supervisor behaviors, and sleep outcomes, measured both subjectively and objectively, are examined in a cross-sectional sample. Study 2 investigates associations among work-to-family conflict, family-supportive supervisor behaviors, and subjective sleep outcomes within a seven-day daily diary framework. Furthermore, workplace …

Discursive Security: F.B.I. Stings And The Nature Of Peace, Adam Testerman

Dissertations and Theses

The current study utilizes Critical Discourse Analysis and Thematic Analysis to study newspaper coverage of F.B.I. sting operations in The New York Times, Washington Post, and USA Today. F.B.I. sting operations are a modern counter-terrorism policy designed to preempt acts of terrorism. This study develops a theoretical approach to understanding F.B.I. sting operations by reviewing the critique of security. The critique of security suggests that nations construct threats in order to produce and maintain ideological and practical hegemony. Thematic categories of the newspaper discourse are formulated and analyzed in the context of security. The study employs aspects of grounded theory …

The Erosion Of Coastal Sediment And Regeneration Of Rhizophora Mangle Following Anthropogenic Disturbance On Turneffe Atoll, Belize, Heather Lyn Hayden

Dissertations and Theses

As communities and managers become aware of the long-term impacts of mangrove loss, estimated at 1-2% per year, interest in sediment erosion and mangrove rehabilitation has increased substantially. In this thesis project I 1) examine erosion rates within coastal fringing Rhizophora mangle ecosystems following mangrove clearing and compare these rates to accretion rates in intact mangroves; and 2) investigate the abiotic factors influencing mangrove seedling survival and regeneration of naturally colonizing R. mangle, in historic mangrove habitat after anthropogenic clearing.

Differences in erosion were compared between patches of open-coast intact and anthropogenically cleared R. mangle to quantify the sediment trapping …

The Role Of Emotional Support Consistency And Child Risk Factors In Predicting Pre-K Cognitive And Social-Emotional Development, Amy Lynn Cannell-Cordier

Dissertations and Theses

The quality of children's daily experiences in preschool classrooms is predictive of their school readiness and later achievement (Duncan et al., 2007; La Paro & Pianta, 2000). One particularly important aspect of these experiences is the quality of emotional support provided by teachers and peers in the classroom (Hamre & Pianta, 2005; Howes et al., 2008; Mashburn, 2008; National Center on Quality Teaching and Learning, 2012). Traditionally, emotional support quality has been calculated as the average of ratings taken across the school year and is meant to represent children's average daily experience, without regard to any variability which exists within …

Constant Interface Temperature Reliability Assessment Method: An Alternative Method For Testing Thermal Interface Material In Products, Christian Amoah-Kusi

Dissertations and Theses

As electronic packages and their thermal solutions become more complex the reliability margins in the thermal solutions diminish and become less tolerant to errors in reliability predictions. The current method of thermally stress testing thermal solutions can be over or under predicting end of life thermal performance. Benefits of accurate testing and modeling are improved silicon yield in manufacturing, improved performance, lower cost thermal solutions, and shortened test times.

The current method of thermally stress testing is to place the entire unit in an elevated isothermal temperature and periodically measure thermal performance. Isothermally aging is not an accurate representation of …

Got Hair That Flows In The Wind: The Complexity Of Hair And Identity Among African American Female Adolescents In Foster Care, Lakindra Michelle Mitchell Dove

Dissertations and Theses

African American children are disproportionately over-represented in the child welfare system. Many of these children linger in the system and experience disconnection from their biological families, communities, cultural beliefs, values, and practices. Familial socialization and cultural exposure are essential to developing a positive ethnic identity and self-concept. For African American female adolescents, hair and hair care are critical areas for such socialization and support. This qualitative study explored the hair and hair care perceptions and experiences of African American female adolescents in foster care. The goal was to examine hair and hair's connection to, and influence on, sense of self …

Study Of Prestige And Resource Control Using Fish Remains From Cathlapotle, A Plankhouse Village On The Lower Columbia River, J. Shoshana Rosenberg

Dissertations and Theses

Social inequality is a trademark of Northwest Coast native societies, and the relationship between social prestige and resource control, particularly resource ownership, is an important research issue on the Northwest Coast. Faunal remains are one potential but as yet underutilized path for examining this relationship. My thesis work takes on this approach through the analysis of fish remains from the Cathlapotle archaeological site (45CL1). Cathlapotle is a large Chinookan village site located on the Lower Columbia River that was extensively excavated in the 1990s. Previous work has established prestige distinctions between houses and house compartments, making it possible to examine …
