Thinking About Work At Home: Implications For Safety At Work, Frankie Guros

Dissertations and Theses

Safety at work is of the utmost importance to employees and the organizations they work for, and as such, it is a central issue for occupational health psychology. Although dramatic decreases in the number of worker injuries and fatalities have been observed over the last several decades, safety remains a principal concern for organizations. This is especially true in occupations in which employees face serious threats to their personal safety, such as correctional officers (COs). While a number of studies have identified workplace factors that contribute to worker safety, few have attempted to draw a link between employee nonwork experiences …

Exploring Relationships Between Entrepreneurship Education And Students’ Entrepreneurial Intentions: A Mixed Method Study Of Entrepreneurial Pedagogies At Chilean Universities, Paulina Andrea Gutierrez Zepeda

Dissertations and Theses

Entrepreneurs play a major role in the 21^st century economy, especially in developing countries such as Chile. Entrepreneurial individuals generate innovative ideas, create jobs, and push older businesses to improve competitiveness. To encourage entrepreneurial skills and mindset among the next generation of students, different public and private initiatives have started to include entrepreneurship education (EE) in all levels of education, especially in higher education.

Nowadays, EE is not only about business creation, it is about educating individuals to be capable of creating opportunities using entrepreneurial skills to deal with complex and uncertain environments. Yet, while much is known about …

The Development Of Personal Resources In The Academic Domain: Age Differences In The Evolution Of Coping And Perceived Control And The Process Structures That Facilitate Academic Engagement, Teresa Marie Greene

Dissertations and Theses

Studies investigating the development of perceived control and coping in the academic domain generally adopt an individual differences approach, reporting mean-level changes in these and associated constructs. Very few studies attempt to chart the process by which these personal resources exert individual and combined influences on academic outcomes, such as motivation and achievement, in light of normative developmental changes. Further, a consideration of reciprocal influences of these constructs on developmental changes and the contribution of social partners to these processes is not common.

Conceptualized from a systems perspective, this study integrates these different approaches in a longitudinal inquiry into the …

Insights Into The Mental Imagery And Gestural Awareness Of Representational Gestures Produced In Everyday Talk: An Exploratory Study Of Using Participants' Comments As Data, Sue M. Wendel

Dissertations and Theses

To better understand representational gestures used in everyday talk, this study explores the ways participants talk about their own mental imagery and gestural awareness, and how their comments affect analysis. Literature pertaining to representational gestures, mental imagery, gestural awareness, and self-report data provide the theoretical framework for the study's design and implementation. Data is drawn from observations of two video recorded dyads engaged in everyday conversation, and four audio recorded interviews with each participant individually as they viewed and commented on selected video segments in which they had produced a representational gesture. Findings indicate that participants talked about mental imagery …

Fathers Caring For Children With Special Health Care Needs: Experiences Of Work-Life Fit, Claudia Sellmaier

Dissertations and Theses

Research about employed fathers of children with special health care needs (SHCN) is still limited, leaving fathers without the necessary workplace and community supports to better integrate work and life. Caregivers with exceptional caregiving responsibilities report greater levels of work-family conflict and considerable caregiver strain, as well as negative employment and financial consequences related to their caregiving responsibilities. These caregivers often struggle to access community supports such as childcare, after-school care, and support from friends and neighbors.

This study provides insights into the types of job, home, and community resources that are relevant for fathers of children with SHCN in …

Beyond Fruit: Examining Community In A Community Orchard, Emily Jane Becker

Dissertations and Theses

The Fruits of Diversity Community Orchard, located in Portland, Oregon in an affordable housing neighborhood, is a site of alternative food provisioning in which a group of people, organized by two nonprofits, work together to manage fruit and nut producing plants. Through conversations with volunteers who participate regularly and participant observation, this study explores the questions: What does community mean in the context of a community orchard? In what ways does partnering with a nonprofit from outside the neighborhood influence community and the way the project is operationalized?

This thesis situates community orchards within the literature on alternative food networks …

Principal Leadership Practices In High Poverty K-5 Model Schools In Oregon, Janice Marie Adams

Dissertations and Theses

Children living in poverty in the United States face some of life's greatest challenges, including achieving academic success in school. Evidence is also emerging of a growing income disparity in America that affects families, communities and local labor markets in ways that can undermine the effectiveness of schools serving disadvantaged populations (Duncan & Murnane, 2011). Evidence exists, however, that high academic performance is within the reach of all children in high poverty schools, and that principal leadership is a contributing factor.

This study examined principal leadership practices in three high poverty K-5 elementary schools in Oregon identified as Model schools …

Metaphorical Framing Of Obesity, Ryan Paul Hofer

Dissertations and Theses

The study of metaphor has moved from abstraction and poetics into the realms of cognitive science and cultural studies. Rather than being seen as purely figurative and secondary to literal meaning, investigation of metaphors reveals a close relationship to our processes of reasoning, a capacity to both reveal and cover, and a plasticity that forms within surrounding cultural values. I reviewed current metaphor theory, including its concerns and justifications, and designed a simple survey experiment through the Qualtrix webpage. The survey was distributed via the Amazon Mechanical TURK system. The experiment, in two different versions, briefly described obesity and then …

An Exploration Of Bicyclist Comfort Levels Utilizing Crowdsourced Data, Bryan Philip Blanc

Dissertations and Theses

Bicycle transportation has become a central priority of urban areas invested in improving sustainability, livability, and public health outcomes. Transportation agencies are striving to increase the comfort of their bicycle networks to improve the experience of existing cyclists and to attract new cyclists. The Oregon Department of Transportation sponsored the development of ORcycle, a smartphone application designed to collect cyclist travel, comfort, and safety information throughout Oregon. The sample resulting from the initial deployment of the application between November 2014 and March 2015 is described and analyzed within this thesis. 616 bicycle trips from 148 unique users were geo-matched to …

Supervisor-Specific Outcomes Of A Work-Family Intervention: Evidence From The Work, Family, & Health Study, Mackenna Laine Perry

Dissertations and Theses

Workplace interventions provide a practical and important means of providing support for employees' work-family needs. However, work-family interventions are rare and are generally not thoroughly evaluated. The current study seeks to better understand the impacts of STAR ("Support. Transform. Achieve. Results."), the large-scale work-family intervention developed and implemented by the Work, Family, & Health Network (see Bray et al., 2013). Drawing on Conservation of Resources theory (Hobfoll, 1989), this study examines supervisors' participation in STAR through assessment of three primary supervisor-specific outcomes: training-related views and behaviors, well-being, and the work-family interface. The sample, consisting of 184 supervisors from 30 extended-care …

Inspiring Action: Measuring The Effect Of Motivational Frames On Social Movement Mobilization, Rebecca Louise Smith

Dissertations and Theses

In order to probe how social movement messages foster participant mobilization, this study utilized an experimental design to investigate collective action frames, core messaging tasks that define problems, assign blame, convey a plan of action, and inspire participation. The study compared the effects of climate change messages that contain motivational frames with those that do not, incorporating the influence of resonance, and exposure to competing and counter frames. Results revealed that motivational frames contributed to mobilization, especially intention to act, under conditions of resonance and with exposure to counter frames. Salience primed participants to respond to motivational frames, however for …

Perspectives On The College Readiness And Outcome Achievement Of Former Intensive English Language Program (Ielp) Students, Meghan Oswalt

Dissertations and Theses

Program evaluation (PE) is important for ESL programs but also difficult. As the scope of PE has grown, student voices have increasingly been included. Alumni provide unique perspectives, but Portland State University's (PSU) Intensive English Language Program (IELP) currently has no exit survey. Furthermore, little research uses alumni data, so this constructivist, mixed-methods study used data triangulation to compare the perceptions of former IELP students with those of three other stakeholder groups -- the topic: IELP student preparedness for PSU. Both online surveys and interviews were conducted, and participants included 63 former and 33 current IELP students, 27 IELP faculty …

Training "In A Good Way": Evaluating The Effect Of A Culturally Responsive Pre-Training Intervention On Learning And Motivation, Adam Thomas Murry

Dissertations and Theses

Employee Training and Development (T&D) is a crucial component to an organization’s success and its ability to remain competitive. Although researchers in the field have discovered ways to enhance the effectiveness of training programs through the design, delivery, and evaluation process, research has not provided empirically-based recommendations for how to best train individuals whose cultural backgrounds may influence receptiveness of training curriculum. This is particularly relevant for employees whose cultural groups have been historically discriminated against, where cultural norms implicit in the training design may be met with resistance on behalf of the trainees. In the field of multicultural education, …

Expressionist Art And Drama Before, During, And After The Weimar Republic, Shane Michael Kennedy

Dissertations and Theses

Expressionism was the major literary and art form in Germany beginning in the early 20th century. It flourished before and during World War I and continued to be the dominant art for of the Early Weimar Republic. By 1924, Neue Sachlichkeit replaced Expressionism as the dominant art form in Germany. Many Expressionists claimed they were never truly apart of Expressionism. However, in the periodization and canonization many of these young artists are labeled as Expressionist.

This thesis examines the periodization and canonization of Expression in art, drama, and film and proves that Expressionism began much earlier than scholars believe and …

Assessing The Impact Of Restrictiveness And Placement Type On Transition-Related Outcomes For Youth With And Without Disabilities Aging Out Of Foster Care, Jessica Danielle Schmidt

Dissertations and Theses

Nearly 23,000 youth age out of the foster care system between the ages of 18 and 21 each year in a transition fraught with challenges and barriers. These young people often lack developmentally appropriate experiences and exposure to necessary knowledge, role modeling, skill building, and long-term social support to promote positive transitions to adulthood while in foster care. As a result, young people who exit care face an array of poor adult outcomes. Nearly 60% of transition-aged foster youth experience a disability, and as such, face compounded challenges exiting foster care. While the examination of young adult outcomes for youth …

A Queer Liberation Movement? A Qualitative Content Analysis Of Queer Liberation Organizations, Investigating Whether They Are Building A Separate Social Movement, Joseph Nicholas Defilippis

Dissertations and Theses

In the last forty years, U.S. national and statewide LGBT organizations, in pursuit of "equality" through a limited and focused agenda, have made remarkably swift progress moving that agenda forward. However, their agenda has been frequently criticized as prioritizing the interests of White, middle-class gay men and lesbians and ignoring the needs of other LGBT people. In their shadows have emerged numerous grassroots organizations led by queer people of color, transgender people, and low-income LGBT people. These "queer liberation" groups have often been viewed as the left wing of the GRM, but have not been extensively studied. My research investigated …

Mistrust: An Exploration Of African Americans' Attitudes And Perspectives Toward Healthcare, Adolfo Gabriel Cuevas

Dissertations and Theses

This dissertation explored mistrust through focus group discussions (study 1), responses to standardized laboratory vignettes (study 2), and survey questionnaires (study 3). In the first study, I found that African American community members (N=60) experienced perceived discrimination, medical mistrust, and poor communication in numerous and interrelated ways. For example, medical mistrust occurred when clinicians did not convey respect to patients, leaving patients to wonder whether their clinician's treatment was discriminatory or not. Based on these findings, I wanted to see whether these experiences of perceived discrimination and mistrust were related to other dimensions of Black experience, such as racial identity. …

Investigating The Impact Of Sibling Foster Care On Placement Stability, Jeffrey David Waid

Dissertations and Theses

Sibling relationships are an important, yet under investigated aspect of foster care research. Despite the fact that between 65-85% of children in care have brothers and sisters, only recently have child welfare researchers begun to explore the complex and dynamic nature of sibling relationships in substitute care settings. Although cross-sectional and longitudinal studies suggest differences in placement stability and permanency outcomes for siblings placed together versus those placed separately, the conditions under which sibling relationships influence placement stability, permanency, and well-being in foster care settings remain unknown.

This dissertation investigated how family dynamics and home setting characteristics influenced the likelihood …

Ninth Grade Student Responses To Authentic Science Instruction, Michael Steven Ellison

Dissertations and Theses

This mixed methods case study documents an effort to implement authentic science and engineering instruction in one teacher's ninth grade science classrooms in a science-focused public school. The research framework and methodology is a derivative of work developed and reported by Newmann and others (Newmann & Associates, 1996). Based on a working definition of authenticity, data were collected for eight months on the authenticity in the experienced teacher's pedagogy and in student performance. Authenticity was defined as the degree to which a classroom lesson, an assessment task, or an example of student performance demonstrates construction of knowledge through use of …

A Spline Framework For Optimal Representation Of Semiperiodic Signals, Farzin G. Guilak

Dissertations and Theses

Semiperiodic signals possess an underlying periodicity, but their constituent spectral components include stochastic elements which make it impossible to analytically determine locations of the signal's critical points. Mathematically, a signal's critical points are those at which it is not differentiable or where its derivative is zero. In some domains they represent characteristic points, which are locations indicating important changes in the underlying process reflected by the signal.

For many applications in healthcare, knowledge of precise locations of these points provides key insight for analytic, diagnostic, and therapeutic purposes. For example, given an appropriate signal they might indicate the start or …

A Critical Race Analysis Of Travel For Transformation: Pedagogy For The Privileged Or Vehicle For Socio-Cultural Transformation?, James Arthur Gambrell

Dissertations and Theses

Transformative learning theory (TLT) describes the process of reframing discriminative, untenable worldviews with a more inclusive, permeable, and reflective epistemology. Although TLT has been around for more than 50 years, few studies empirically engage critical theoretical frameworks to move beyond personal learning to identify the impacts of transformation on society. Through a critical race theory (CRT) framework, this study analyzed how the participants' socio-cultural identities (race, class, gender, sexuality, and heritage language) impacted the transformative learning of eight study-abroad students from a medium-sized, rural Midwestern university. Focusing on the extent to which the participants experienced the elements of transformative …

Therapy And The Nontraditional Transgender Narrative, Dylan Ellingson Waller

Dissertations and Theses

The history of transgender identity is inextricable from the mental health industry. Since the late 1970's transgender people have required permission from mental health professionals to make medical modifications to their sex characteristics. During the time of this research, it was difficult for transgender individuals to receive the hormones or surgeries they desire without first being diagnosed with Gender Identity Disorder (GID).

This study applies labeling theory to the label of GID. Labeling theory poses that if an individual is labeled with a mental illness, they will either reject or accept the label. Acceptance of the mentally ill label will …

The Multilevel Effects Of Supervisor Adaptability On Training Effectiveness And Employee Job Satisfaction, Joseph Alvin Sherwood

Dissertations and Theses

The present study explored the multilevel effects of supervisor learning adaptability on training effectiveness, and post-training employee job satisfaction in a work-family and safety-based intervention aimed at increasing family supportive supervisor behaviors (FSSB) and safety behaviors. Using a sample of 291 municipal public works field workers from two independent organizations, it was hypothesized that supervisor adaptability positively relates to post-training FSSB and employee job satisfaction. Specifically, it was hypothesized that learning adaptability prepares those supervisors to be more inclined to engage actively in training, thereby increasing employee reported FSSBs more significantly for those supervisors and leading to intervention target results, …

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 …

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 …

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 …

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 …

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 …

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 …
