Expressive Motion Synthesis For Robot Actors In Robot Theatre, Mathias I. Sunardi

Dissertations and Theses

Lately, personal and entertainment robotics are becoming more and more common. In this thesis, the application of entertainment robots in the context of a Robot Theatre is studied. Specifically, the thesis focuses on the synthesis of expressive movements or animations for the robot performers (Robot Actors). The novel paradigm emerged from computer animation is to represent the motion data as a set of signals. Thus, preprogrammed motion data can be quickly modified using common signal processing techniques such as multiresolution filtering and spectral analysis. However, manual adjustments of the filtering and spectral methods parameters, and good artistic skills are still …

Spousal Crossover Effects Of Job Demands On Health, Rachel Jane Daniels

Dissertations and Theses

The primary goal of this dissertation was to examine the crossover effects of an individual's job demands on the perceived health of the spouse. Using a sample of grocery store employees and their partners, crossover relationships were examined for 90 dyads using Structural Equation Modeling. Although the models had good fit, the proposed direct crossover relationships of job demands on health were not supported. Job demands of one partner did not significantly predict health outcomes in the other partner; although follow-up analyses found significant crossover of women's job satisfaction on men's mental health scores. An additional crossover relationship was supported …

Juvenile Sex Offenders: A Consideration Of Attachment Deficits In The Etiology Of Offending, Lee Anna Knox

Dissertations and Theses

Child sexual abuse is a serious and widespread problem that has been associated with a variety of short and long term consequences to victims, offenders, families, communities and society at large. In recent years, it has been recognized that up to 40% of sexual offenses occur at the hands of adolescent offenders (between 12-18 years of age). The literature suggests that early childhood familial experiences, specifically attachment deficits and experiencing abuse in childhood may be associated with offending behavior in adolescents. Important developments in attachment theory are reviewed and discussed as they relate to the etiology of offending behavior and …

City Management Theory And Practice: A Foundation For Educating The Next Generation Of Local Government Administrators, Scott Douglas Lazenby

Dissertations and Theses

Due to the retirement of the baby boom generation, many individuals, in a relatively short period of time, will need to be trained and educated to step into local government senior leadership positions. Ideally, the education and training of this new leadership cadre should be guided by a well known and proven body of theory that helps us understand the competencies the next generation of public service need to possess in order to be effective in their work. The purpose of this research is to assess whether such a body of work exists and, if so, whether it is successfully …

Hardiness, Well-Being, And Health: A Meta-Analytic Summary Of Three Decades Of Research, Celina Marie Oliver

Dissertations and Theses

In recent decades, as scientific understanding regarding the effects of stress on health and well-being has grown, researchers have shown increasing interest in personal factors such as hardiness that may enhance one's ability to remain resilient under stressful conditions. Hardiness is a complex trait composed of three components (commitment, control, and challenge) that combine synergistically to increase stress tolerance. Over time, a large and complex body of research has accumulated, and while many qualitative reviews have been conducted, quantitative summaries remain rare. This study provides an empirical synthesis of research findings examining the relationships between hardiness and correlates related to …

The study's purposes included: investigating professional developers' experience and practice in inquiry groups; amplifying professional developers' voices in the professional development field; and suggesting recommendations for educational leadership.

A literature review developed a framework grounded in social, situated learning theory. It revealed that professional development needed to provide teachers with opportunities to collaborate in inquiry groups to solve problems …

Operationalizing The Antecedents Of Work-Family Positive Spillover: A Longitudinal Study, Kristi Lynn Zimmerman

Dissertations and Theses

The primary goal of the current study was to examine the antecedents of work-to-family and family-to-work positive spillover. This dissertation examined the relationship between work, family, and personal domain resources with the outcomes of work-to-family and family-to-work positive spillover. Specifically, five types of resources were tested as predictors of positive spillover as proposed by Greenhaus and Powell's (2006) theory of work-family enrichment. To test these relationships, constructs from the work and family domains were used to operationalize each of the proposed resources, and a longitudinal research design was applied in order to establish these resources as predictors of positive spillover. …

Primary Care, Males, Masculinity, And Suicide : A Grounded Theory Study, John Thomas Casey

Dissertations and Theses

Suicide completion in the United States is a public health problem that claims over 30,000 lives annually. Most of these suicide victims are white males who die by firearm, and who typically are not taking antidepressant medication and are not involved in mental health treatment at the time of death. Depression is closely linked to suicide death, and treatment for depression is provided mainly within primary health care settings where most suicide decedents have been seen at some point in the year prior to their death. The rate of male depression is likely under-reported, partly due to gender-bias within primary …

A Positive Development View Of Risk-Taking : Attachment, Mental Health, Internal Control, And Life Engagement, Lauren Michelle Denneson

Dissertations and Theses

Previous research has primarily focused on potential negative outcomes of risk-taking (e.g., Byrnes, Miller, & Schafer, 1999). However, risk-taking may be beneficial for our mental health. Currently, the United States (U.S.) is seeing an increase in the prevalence and incidence of anxiety and depressive symptoms (N1MH, 2002, 2003, 2006; WHO, 2001). At the same time, individuals in the U.S. spend a large percentage of time in low-energy, "time wasting" activities, such as watching television (United States Department of Labor, 2007), which is in discord with how our stress response functions optimally (Sapolsky, 1998; Dhabhar, 2002). Furthermore, attachment theory posits a …

Developing One's Self: Adoption And Identity Formation Through The Eyes Of Transracially Adopted Native American Adults, Jody Becker-Green

Dissertations and Theses

Life story methods were used to explore the contextual factors that influenced the experiences and identity formation of seven Native American adults who were transracially adopted prior to the passage of the Indian Child Welfare Act of 1978. These methods provided a deeper understanding of how these individuals have integrated their adoption experiences into their evolving sense of self. The life story methodology offered a way to acknowledge and validate participants' life experiences and allowed for the collection of rich information from the perspectives of the adoptees.

The life story interviews were structured to gather information on the influence of …

Dependent Care And Work-Life Outcomes : Comparing Exceptional Care And Typical Care Responsibilities, Lisa Maureen Stewart

Dissertations and Theses

Exceptional care responsibilities describe the experiences of caring for a dependent with a chronic illness or disability (Roundtree & Lynch, 2006). To date research on exceptional care responsibilities has occurred outside of the traditional work-life field. This study positions exceptional care responsibilities as a type of dependent care that goes beyond that of typical care responsibilities and argues efforts are needed both within the workplace and the community to address the challenges faced by employees with disability-related dependent care responsibilities.

The influence of supports within the workplace on the work-life barriers and related outcomes of employees with typical care and …

Quaternions, Octonions, And The Quantization Of Games, Aden Omar Ahmed

Dissertations and Theses

We present an effect on classical games that is obtained by replacing the notion of probability distribution with the notions of quantum superposition and measurement. Our particular focus will be on two and three player games where each player has precisely two pure strategic choices. Games in normal form are represented as "payoff" functions.

Game quantization requires the extension of these functions to much larger domains. The main result of this work is the co-ordinatization of these extended functions by either the quaternions or octonions in order to obtain computationally friendly versions of these functions. This computational capability is then …

'Conflict Analysis:' Exploring The Role Of Kuwait In Mediation In The Middle East, Abdullah R. Al Saleh

Dissertations and Theses

The Middle East is a large geographical area, and while people think of it as a homogeneous area in terms of language and culture, the region IS actually more of a melting pot of ethnic, religious, racial and linguistic groups. Understanding the distinctions between these groups is of paramount importance to understanding the region. Historical rivalries between some groups, for example, Sunni and Shia Muslims, go back hundreds, perhaps thousands, of years. Yet, people continue with life. How do countries continue to deal with each other when there are open, unsettled questions, such as boundaries or control of islands? Is …

Students Who Are Moms: How Do They Do It?, Rhianna Marie Derscheid

Dissertations and Theses

Women with children are the fastest growing population of students within higher education. Women with children attempt to obtain a college degree for varied reasons, including self-development, social mobility, and to be a good role model for their children. Student moms face several obstacles in their attempts to obtain a college degree including financial constraints, childcare issues, marginalization, time constraints, and isolation. There is a paucity of research on student moms and the factors that contribute to their successful completion of a college degree. More research is needed to understand student moms’ experiences and to develop effective support programs within …

Japanese International Graduate Students In U.S. Higher Education Classrooms: An Investigation Of Their Pedagogical And Epistemological Challenges And Supports, Miki Yamashita

Dissertations and Theses

International students have long been an important part of the U.S. higher education community, but generally they have received inadequate attention in the classroom. Also, American teaching and learning strategies have not taken full advantage of international diversity. The purpose of this narrative study was to qualitatively understand the experiences of Japanese graduate students in U.S. higher education classrooms. The study highlights the challenges that Japanese graduate students faced due to cultural differences, pedagogical differences, and language problems and provides a number of suggestions for faculty, domestic students, and institutions to help create a more welcoming environment for Japanese graduate …

Peer Network Emergence And Change In The Classroom: A Multiple Systems Perspective, Nicole Ann Sage

Dissertations and Theses

This study examined peer group processes in the classroom that can potentially explain how motivationally "rich" children get "richer" whereas motivationally "poor" children get "poorer." In contrast to research on group processes which focuses on socialization from group to individual, this study focuses on contributions from the individual to his/her group. The viewpoint taken for this study is that children actively choose group members based on their own self-system state, thereby creating their own peer environments in which they develop.Viewed as open complex systems, children's natural peer groups were examined using data collected from students and their teachers at five …

The Nature Of People's Perceptions Of Wolves, Laura Briana Nobel

Dissertations and Theses

European immigrants once regarded wolves as the "devil in disguise" (Lopez, 1978, p.40). With our growing awareness of other cultural perspectives and flourishing body of scientific knowledge with regard to wolves' behavior, our perceptions of wolves have become more complicated and nuanced. Our collective awareness of the environment in which we live also gathers complexity. I examine these issues in this study. Wolves are returning to Oregon. The arrival of wolf B-45 in 1999 heralded the beginning of the return of wild wolves to Oregon. More wolves are expected to cross the border as young sub-adults disperse from the growing …

Sex Work And Moral Conflict: Enhancing The Quality Of Public Discourse Using Photovoice Method, Crystal Renee Tenty

Dissertations and Theses

This thesis uses an advocacy/participatory framework and moral conflict theory to examine the opposing ideas: and interests of parties involved in the issue of prostitution on 82^nd Avenue in Portland, Oregon. It locates areas of contention within the larger dominant feminist discourse, which views sex work as either a form of violence and exploitation or as a form of legitimate free-contract labor. The thesis shows how the intractable moral conflict between these differing feminist theories and values can be mediated using participatory data collection techniques.

Ethnographic data was collected and analyzed from 11 women working in the sex industry …

The Relationship Of Group Support, Majority Status, And Interpersonal Dependency In Predicting Intimate Partner Violence, Mary Elisabeth Gray

Dissertations and Theses

One of the most common community responses to intimate partner violence is batterer intervention programs (BIPs), which are aimed at ending perpetrators' violent behavior. Unfortunately, however, the success rates of BIPs are questionable (Aldarondo, 2002; Gondolf, 2002) and we do not know what factors of the program facilitate decreases in abusive behavior when this does occur. Specifically, it is unknown whether and how individual characteristics interact with intervention group dynamics to facilitate change. To better understand this gap in the literature, this study investigated the relationship between social support, group majority-minority status, and interpersonal dependency in predicting intimate partner violence. …

Literacy Leadership In Secondary Schools: A Case Study Of Teaching And Learning In Two School Districts, Gregory Berry

Dissertations and Theses

Improvement in literacy learning in secondary schools requires a dual focus: a district and school organizational leadership approach, and a classroom- and instruction-focused approach. To help close the achievement gap and improve learning for all students, whole school reform efforts must be focused on literacy. Elements of whole school reform may include professional development programs such as professional learning communities, peer coaching, and literacy coaching. The sociocultural contexts that these approaches incorporate can help improve the learning of both teachers and students and can bring about significant secondary school reform and academic improvement.

This dissertation study is a qualitative, collective, …

Factors Associated With Inclusion Of Spirituality In Secular Social Work Education, Leslie Grace Wuest

Dissertations and Theses

In a diverse society, social work practitioners must be able to work with and respect people from a wide variety of cultures and ethnicities and with different value systems and ideological perspectives, including spiritual or religious beliefs. Accordingly, social work education has begun to incorporate the topic of spirituality. This study builds upon previous studies by Dudley and Helfgott (1990) and Sheridan et al. (1994) which focused on views of faculty members regarding spirituality in social work education and support for a course on spirituality in the social work curriculum. This study goes on to examine inclusion of spirituality in …

The Institutionalization Of Diversity And Gender Equity Norms And Values In Higher Education Settings, Rowanna Lynn Carpenter

Dissertations and Theses

Universities in the United States increasingly experience demographic, business, and community pressure to hire, retain, and educate women and ethnic minority faculty, staff, and students. Responses to this pressure have changed over time from isolated open-door initiatives to comprehensive diversity initiatives designed to create welcoming campus environments for people of all backgrounds. Current literature on the assessment of diversity initiatives in higher education suggests the need to use approaches that include attention to the entire university, and to institutionalize the norms and values associated with diversity initiatives as part of the change process. Despite this shift toward a comprehensive understanding …

More Than Screening Tools? : An Examination Of Preliminary Applicant Evaluation Methods, Matthew Eric Paronto

Dissertations and Theses

The increased prevalence of technology in organizations has had significant impacts on the recruiting, screening, and hiring processes. However, little is known regarding whether preliminary applicant evaluation methods provide meaningful candidate information beyond possession of minimum qualifications. To address this gap in the literature, two preliminary applicant evaluation procedures used at a major utility company were examined across two separate studies.

Study 1 examined online applicant prescreening protocols across three positions. Archival prescreening data from 5,619 applicants were analyzed in terms of item characteristics that distinguished candidates at different points in the score distribution (high vs. low; highest vs. high), …

Traumatic Experience Scale For Jurors (Tesj), Michael James Krummel

Dissertations and Theses

This comprehensive dissertation describes research that involved the development of a paper-and-pencil tool to inventory juror stress level(s) resulting from common types of Washington criminal and civil trials. It includes a general explanation of its rationale and development, and provides norms as well as evidence of its reliability and validity. Untreated stress can lead to several well-documented mental health conditions, the most serious two being part of this research: Acute Stress Disorder and Post-traumatic Stress Disorder. The research on stress, trauma, the assessment of stress and trauma, and related therapeutic interventions have not been well correlated to the vicarious stress …

Las Pioneras : New Immigrant Destinations And The Gendered Experiences Of Latina Immigrants, Angie Pamela Mejia

Dissertations and Theses

Are experiences with migration affecting culturally specific gendered practices, roles, attitudes, and ideologies of Mexican women and men? Which experiences reinforce patriarchy? Which experiences transform patriarchy? This thesis proposes that Mexican immigrant women will subscribe to and enact different gendered behaviors depending upon their perception of gendered gains. Various factors, such as time of arrival, previous experiences with negative machismos, and workforce participation affect how they construct gendered identities. The context where bargaining occurs-whether itwas the home, the community, or the workplace - inform women of what strategies they need implement in order to negotiate with patriarchy. This study employs …

Role Of Food Neophobia, Food Attitudes And Written Information On The Acceptance Of Novel Fish Products : A Cross-Cultural Study, Koei Kudo

Dissertations and Theses

The present research used an integrative and multi-disciplinary approach to investigate the relations among food attitudes, food neophobia and acceptance of novel and familiar albacore tuna dishes for Japanese and U.S. consumers.

A pilot study selected seasonings and cooking methods that were familiar or novel to each culture, and identified the most relevant health benefits of omega-3 fatty acids (FA).

The main study employed a self-reported, web-based questionnaire where back-translation maximized the cross-cultural equivalency of US and Japanese versions. Scales of food neophobia (Crystallized Neophobia Scale, or CNS) and attitudes towards foods (Health-, Pleasure- and Convenience-Oriented Food Attitudes Scale, or …

"Do I Really Belong Here?" The Effects Of Difference In Paths Through Higher Education On Graduate Student Perception On Legitimacy, Tina Dawn Lillian Burdsall

Dissertations and Theses

Why do some master's level students feel confident in completing their programs and some do not? Why do some feel connected to their department and some do not? Why do some feel legitimate as graduate students and some do not? This research proposes that there may be differences in how master's students understand the graduate student role based on whether they went directly from high-school through their bachelor's to their master's, or if they took time off between their bachelor's and master's program. This thesis used in-depth interviews with twelve second-year master's students at Portland State University to explore these …

Developing A Sense Of Academic Ownership : A Longitudinal Analysis, Gwen Catherine Marchand

Dissertations and Theses

Student responsibility has emerged as a key developmental task, particularly during the transition to middle school. A developmental and motivational perspective was taken for the present study that emphasized agency, ownership, and engagement as key parts of the development of student responsibility. Self-determination Theory (SDT) was selected as the overarching framework for the present investigation due to the theory's emphasis on autonomy, which refers to the experience of oneself as the authentic origin of one's own actions (Deci & Ryan, 1985). In SDT, the construct of autonomy is used to integrate views of intrinsic and extrinsic motivation and to differentiate …

The Impact Of The Swingshift Options School Alternative Educational Pathway On At-Risk Middle School Students' Transition To High School, Carol Rutan Smith

Dissertations and Theses

The purpose of this qualitative and quantitative study was to understand the perspectives of so-called at-risk middle school students who participated in an alternative mid-level program and the support that program might have provided in their transition into high school. The study gives voice to such students and sheds light on the type of programs and practices that reduce their risk for dropping out of school. Dynarski and Gleason (2002) reported that early adolescence is a period of both enormous opportunity and enormous risk for dropping out of school.

Participants were former students in the Swingshift Options School (SOS) program …
