Permission To Play: A District's Initiative To Innovate Kindergarten And Promote Developmentally Appropriate Practices, Cristin Mcdonough

Dissertations and Theses

Kindergarten's original purpose was to promote socialization skills for young children using play. However, recent research has shown an increased focus on teaching literacy and math skills, combined with pronounced increases in more advanced academic tasks and activities. Given this shift in kindergarten, as well as a lack of professional development for teachers to assist them in promoting developmentally appropriate practices, the Kindergarten Innovation Cohort was created in the Portland School District to address these needs for both students and teachers. Using findings from interviews and field notes, the current study addresses the question: What does the implementation of the …

Varecia Rubra (Red Ruffed Lemur) Diel Activity And Calling At Andranobe, Masoala National Park, Madagascar, Hannah Elena Hilden-Reid

Dissertations and Theses

With respect to the natural variation in abiotic and biotic conditions present between daytime and nighttime periods, many animal species show evolutionary adaptations specialized for diurnality, nocturnality, or crepuscularity. Biologists have traditionally viewed categorizations of this kind as fixed within taxonomic groups, emphasizing how intricately species’ survival is contingent on the ability to adapt to low light, high light, or twilight conditions. However, movement away from such distinct temporal niche categories began within chronobiological studies following the discovery of more flexible patterns of activity in numerous taxa during the late 1970s. This shift generated increased interest in elucidating the complex …

The Wage Of Wellness: The Relationship Between Socioeconomic Status, Race, And Work Recovery, Emily Julia Ready

Dissertations and Theses

A substantial share of the workforce is made up of low-income workers. Many of these workers fall below the federal poverty line and are considered low socioeconomic status (SES) and are disproportionately more likely to be racial minorities. However, this population is often neglected in the industrial-organizational psychological literature. Specifically, work recovery research has not considered the unique life circumstances of this particular group in the development of the research questions, theoretical framework, or practical implications in relation to this phenomenon. The purpose of the current study is to understand the relationship between socioeconomic status, race, and work recovery experiences …

The Relationship Between Adverse Childhood Experiences And Juvenile Offender Typology, Aliza Beth Lipman

Dissertations and Theses

Approximately 1 in 5 girls and in 20 boys in the United States are victims of child sexual assault every year. Child sexual assault can lead to multiple negative short term and long-term impacts affecting general health, mental health, interpersonal relationships, socio-economic status, criminal behavior and more. Prevention research focuses on a thorough understanding of the perpetrators of assault and the context surrounding offenses in order to reduce and prevent assault. Within this research, juvenile offenders are perceived as a single homogenous group whereas adult offenders are consistently specified based on offender and offense characteristics. The exploration of the relationship …

Corporatizing Violence: Targeted Repression Of Indigenous Dissent In Democratic States, Laikaika Layne Rivera

Dissertations and Theses

This thesis explores state repression of disruptive protests against private development projects in democracies. Using a mixed methods approach, including logistic regression and case studies, the research identifies key factors influencing repression. Indigenous leadership, fragmented public opposition, and private elite influence increase the likelihood of violent repression. The findings suggest that when public resistance is insufficient against powerful private interests, coercive institutions resort to violent strategies to quell disruptions and signal increased costs for future dissent. State repression is more likely when the protest movement is comprised of Indigenous groups than compared to those of the general public. The study …

A Survey Of North American Electric Bicycle Owners, Cameron Steven Bennett

This thesis presents an investigation of e-bike owners in North America, complementing previous efforts in 2013 and 2017, and suggests implications for North American transportation planning.

An online survey was distributed to e-bike owners in the United States and Canada through email outreach, purchase incentive programs, and social media. The survey included questions on the respondents’ demographics, e-bikes, purchase decisions, travel behavior, perceptions of e-bikes, crash experience, maintenance needs, and receipt …

Faculty Mentors' Influence On Latino/A/X Stem Undergraduates' Stem Identity Development, Sandy Cerda-Lezama

Dissertations and Theses

Despite Latino/a/x college student attendance rising substantially over the past decades, their graduation rates do not match the increased admission rates. In addition, Latino/a/x students are considerably under-represented in STEM. However, research suggests that when these students are encouraged by social partners to have meaningful participation and given resources such as mentoring, this eases the barriers they experience. The current study utilized interviews with 11 Latino/a/x STEM undergraduates (aged 18-29) to understand how faculty mentors influence their STEM identity development. Students shared answers about how faculty promoted and inhibited their STEM identity development through conversations about their sense of competence, …

Understanding The Other: Mentor Ethnocultural Empathy And Relationship Quality And Duration In Youth Mentoring, Miriam Miranda-Diaz

Dissertations and Theses

Given the positive youth outcomes associated with participation in mentoring programs, there is growing interest to explore factors associated with mentoring relationship quality and duration in formal youth mentoring programs. In comparison to the majority of volunteer mentors, many young people participating in formal mentoring programs are of a racial-ethnic minority group and tend to be economically disadvantaged. This study investigates factors associated with these socio-cultural background differences between mentors and mentees. More specifically, this study investigates the association between a mentor's level of ethnocultural empathy, as reflected in empathic perspective-taking and acceptance of cultural differences, and the quality and …

The data reveal that social media use directly influences the lives and actions of Queer rural youth, who use the space to build social connections, shape their personal identities, and seek advice pertaining to their in-person lives and decisions. By using these spaces, Queer rural youth build both bonding and bridging social capital, learn to subvert restrictions to their Internet access, …

It Takes A Village: An Examination Of Social Relationships And Mental Health, Em Francis Trubits

Dissertations and Theses

Social relationships are impactful to mental health and well-being, both positively and negatively. Different sources of support vary in their ability to meet our needs and ultimately influence our well-being. While research has examined aspects of supportive and harmful social relationships and mental health, much of this work is cross-sectional or limited to a single source of support. This dissertation aimed to better elucidate the relationship between social relationships and mental health by integrating multiple theoretical perspectives and multiple sources of support, in a series of three empirical studies in order to inform theory and interventions targeting mental health of …

The Mirror Project: Reflections On The Experiences Of African-American Female Adolescents Experiencing Foster Care, Bahia Anise-Cross Degruy Overton

Dissertations and Theses

As the author Zora Neale Hurston says, "If you're silent about your pain, they'll kill you and say you enjoyed it." The Mirror Project (MP) aims to break this silence by giving voice to Black women who have experienced foster care in Portland, Oregon during their adolescence. In focus groups and interviews, participants shared their stories. Racial identity development theory, phenomenology and Afrocentric feminist epistemology provided lenses for gaining insight into their experiences in a predominantly white city. The MP revealed six themes: lack of youth engagement in foster care decisions, the need for a cultural lens in social work, …

Latine Dual Language Bilingual Education Teachers' Work Experiences, Nelly Noemi Patiño Cabrera

Dissertations and Theses

Given the increasing concern about the scarcity of Dual Language Bilingual Education (DLBE) teachers, it is crucial to understand the trends in teacher retention and attrition from the perspective of DLBE teachers themselves. DLBE teachers departing from their jobs imposes a significant burden on schools and students and affects the implementation of DLBE programs. To delve into this issue, this critical qualitative study focused on the work experiences of Latine K-5 Spanish/English DLBE teachers. Specifically, this study involved six participants divided into two groups of DLBE teachers in the teaching trajectory: three Latine K-5 Spanish/English DLBE teachers currently teaching in …

The Arab Spring Uprisings In Geopolitical Context, Jake Alan Rutledge

Dissertations and Theses

The question of why revolts, civil wars, and social unrest occur is central in the field of political science. This paper asks that question in the specific context of the 2011 Arab Spring uprisings as a revolutionary wave. Many theories of revolution and social unrest locate their causes in the internal characteristics of the country where they take place, such as the country's demographics or level of economic development. This paper examines the external situation of a country: its relationships with other states and the international community. This paper examines eighteen Arab countries in the Middle East and North Africa …

Understanding Quadrature Modulation By Designing A 7mhz Iq Test Bench To Encode The Polybius Square, William Lee Bradley

Dissertations and Theses

This thesis outlines the design of an IQ Test Bench that allows for experimentation of quadrature modulation techniques. Quadrature modulation utilizes two signals I and Q, 90° out of phase from each other, to greatly increase communication data rates. Using Desmos, a thorough mathematical analysis of waveform mixing is presented, and constellation diagrams are plotted from the results. From this an ancient fire signaling technique known as the Polybius Square is encoded into the system. The IQ Test Bench is built from fundamental components that would be contained within an RFFE: a local oscillator and two frequency mixers. The LO …

Individual And Structural Contributors To Implicit And Explicit Anti-Muslim Bias In The United States, Aeleah M. Granger

Dissertations and Theses

This dissertation consists of two manuscripts addressing the multifaceted nature of Islamophobia in the United States by examining explicit and implicit anti-Muslim bias on individual and structural levels. The first manuscript tests an ideology-threat-attitude-behavior model by estimating the simultaneous mediating effects of threat perceptions on the relationships between individual differences in ideology, Islamophobia (fear of Muslims), and support for an anti-Muslim police surveillance policy. This study (N = 603) finds that individuals who are higher in Social Dominance Orientation (SDO), Right-wing Authoritarianism (RWA), and Nationalism are more likely to perceive Muslims as realistic (power), symbolic (value), and terroristic (safety) …

Political Ideology As Determinative Of Higher Education Funding: Exploring The Distinctions Between Community College And University Funding Under Differing Political Regimes, Paul Brown

Dissertations and Theses

Adequacy of funding for public institutions of higher education in the United States is significantly important to an array of stakeholders, including, state legislative bodies, decision-makers in the arena of higher education, and notably, consumers of higher education. State allocation of resources for higher education demonstrates variability, complicating accurate programmatic planning and budgeting. To assist higher education officials in the task of budget forecasting and resource adequacy, this study will help fill the void in understanding the connections between the political composition of the states’ legislative bodies and funding levels for differing types of higher education institutions. While significant prior …

Exploring Spatial Operations Of Distractor Suppression In The Sense Of Touch, Nicole A. Serino

Dissertations and Theses

The ability to select sensory information in our environment is key to facilitating goal-directed actions. Sensory selection mechanisms are prevalent in all sensory modalities, and can be implemented by enhancing information at the relevant location and/or suppressing neural information outside the focus of attention (a mechanism known as distractor suppression). Although we have a decent understanding of how the brain enhances information within the focus of attention, less is known about the mechanisms that mediate suppression of distractors, especially in sensory modalities outside vision. In this study, we conducted a series of behavioral experiments to investigate the spatial flexibility of …

Brics Currency And Dollar Hegemony: Passing Of The Torch?, Sami Tomaihi

Dissertations and Theses

The dawn of the 21st century has brought with it tremendous uncertainty with regard to the nature of global dominance. As doubts concerning the United States’ viability as a hegemon emerge, questions about how new powers may come to prominence circle (Rapayane, 2020). The BRICS bloc -- consisting of Brazil, Russia, India, China, and South Africa, respectively -- is a collection of regional powers in the developing world that have engaged in a series of high-profile collaborations together in the ostensible interest of increasing global advocacy within the developing world (Kubayi, 2022). One radical means that has been proposed within …

Parasympathethic Nervous Activity And Social Exclusion In Borderline Personality Disorder, Rebecca E. Barnes

Dissertations and Theses

Abstract

The experience of being excluded is universally unpleasant. However, for individuals that suffer from Borderline Personality Disorder (BPD), the experience of social exclusion, or ostracism can be unbearable (Bortolla, et al., 2019). While there is a significant amount of research on physiological reactivity in BPD, no studies adequately connect the parasympathetic nervous system (PNS) responses of people with BPD to social exclusion which is critical to understand as the inability of the PNS of individuals with BPD to adapt to stressors may be a contributing factor to the elevated rate of suicide and suicide attempts in this clinical population …

Enforcement Through Voluntary Participation: The Impact Of Non-Binding Informal Groups On The International Nuclear Nonproliferation Regime, Claudia M. V. Hampton

Dissertations and Theses

The present thesis analyzes the policy impact of the informal group known as the Nuclear Suppliers Group (NSG), a non treaty-bound grouping of states organized to define mutually agreed upon nuclear export controls with the aim of advancing the nonproliferation of nuclear weapons, in line with the values of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). As informal groups or voluntary forms of interstate cooperation are often criticized for their lack of enforcement mechanisms, two case studies in this thesis review the implementation of amendments and changes in national laws for states participating in the NSG (The United …

Divorce As A Growth Process: Marital Separation And Separation-Individuation In Adulthood, Anna Egleson

Dissertations and Theses

Research has focused on the negative effects that divorce has on divorcees, on children of divorced parents, and on society. Research has also shown however that many individuals who go through a divorce emerge happier, more content and satisfied with their choice, even though the process was a painful one. Despite this evidence, there is a gap in the research looking at positive, and growth-related experiences of those who have recently gone through a divorce. Theoretical arguments and clinical observations provide a foundation to support the idea that there is a relationship between separation-individuation in adulthood and the internal shifts …

Identity-Focused Therapist Self-Disclosure In Matched Sexual/Gender Minority Dyads: A Longitudinal Therapy Process-Outcome Study, Brian Thomas Neff

Dissertations and Theses

Therapist self-disclosure (TSD) is a controversial clinical intervention whose benefits and drawbacks remain contested. Notably, no prior research has differentiated explicitly between self-disclosures related to the therapist’s core identities and those peripheral to identity, and qualitative studies suggest that identity-focused therapist self-disclosure (TSD-I) may be beneficial when therapist and patient share at least one marginalized identity. LGBTQ+ people, who experience significant health disparities and utilize psychotherapy more than their heterosexual and cisgender counterparts, could benefit particularly from TSD-I. The mental and physical health challenges facing LGBTQ+ individuals are predominantly explained through minority stress theory, which suggests that societal prejudice and …

Childhood Maltreatment And Posttraumatic Stress Symptom Clusters: The Mediating Role Of Early Maladaptive Schemas, Sydney Nichole Stamatovich

Dissertations and Theses

The current study tested a structural equation model to examine the associations between types of childhood maltreatment (i.e., neglect, punishment, and sexual abuse), Jeffrey Young’s early maladaptive schemas (EMSs), and posttraumatic stress disorder (PTSD) symptom clusters (i.e., avoidance, hyperarousal, intrusion, and negative alterations in cognitions and mood) in a sample of college students. Childhood maltreatment is a pervasive problem in the United States of America and has several short- and long-term physical and psychological consequences. Of note, victims of childhood maltreatment are at an elevated risk of developing PTSD. Further, childhood maltreatment and PTSD are associated with negative alterations in …

The Parentification Of Eldest Daughters, Isabella Loraina Ciarico

The purpose of this study was to understand the experience of eldest daughters and to research if parentification in childhood impacts eldest daughter identities. The goal was to dive deeper into what it means to be the eldest daughter and how being the eldest daughter aligns with parentification. Two research questions guided this study: (a) what is the experience of the eldest daughter, and (b) How does parentification in childhood impact eldest daughter identities? Findings showed the experiences of eldest daughters with parentification.

Online Perceived Social Support And Its Association With Psychopathology In Rural And Urban Youth, Ellen Alexandra Knowles

Dissertations and Theses

Social support is a fundamental aspect of development throughout adolescence. It has been found to buffer against the negative impacts of stress and provide general benefits to one’s well-being. Youth today are exposed to a range of opportunities for socialization with peers, both in-person and online, including interacting with others through texting, social media, video games, and other digital means. These online interactions have begun to be investigated as accessible methods through which adolescents can connect with others and maintain healthy relationships. Furthermore, digital social networks may be most critical for youth from isolated communities, including those from rural areas. …

Exploring Online Feminist Communities And The Male Allyship Experience, Josephine Saighoe

Dissertations and Theses

There has been a growing involvement of men in the feminist cause. Nonetheless, their own experiences as self-identified feminist allies have received inadequate attention within the academic research. Just like female activists, men who identify as feminist activists also make use of such digital platforms to support the activism and make significant contributions to the feminist discourse. In view of this, this study explores the experiences of Ghanaian male feminist allies in addition to delving into their experiences as feminist activists in the digital world and how they navigate the challenges that come with aligning themselves with this cause. Through …

A Pilot Study Exploring The Effectiveness And Feasibilty Of The Peers® Intervention In A Rural/Non-Metropolitan Setting, Blake Elvrum Warner

Dissertations and Theses

Autism Spectrum Disorder (ASD) is classified as a neurodevelopmental disorder characterized by deficits in social communication and restricted and repetitive patterns of behavior. Autistic adolescents often experience a myriad of mental health difficulties which are worsened by lower overall levels of social support. Higher rates of mental health difficulties are reported in rural and non-metropolitan areas where resources are less readily available. Interventions aimed at increasing social skills in autistic adolescents have proven to be an effective way to increase levels of social interaction and support. The Program for the Education and Enrichment of Relational Skills (PEERS®) intervention was developed …

Should I Stay Or Should I Go? A City Manager In Times Of Transition, Patrick William Antonen

Dissertations and Theses

The public administration literature provides many assertions as to what causes a city manager to consider when to remain in their position or relocate to a new position. This study identified variables that impact the decisions to change cities. This research surveyed current city managers in northern Midwest states to explore which variables make a difference. The variables were categorized to include considerations about personal concerns, career motivations, and organizational contexts. Simple analysis suggests that a decision to change cities is very much influenced by the perceived dysfunction of the city council and political or interest groups that influence the …

Impulsive Behavior In The Context Of A Substance Use Treatment Seeking Sample: A Conditional Process Analysis Of Childhood Maltreatment, Experiential Avoidance, And Cognitive Fusion, Emily Kalantar

Dissertations and Theses

Substance misuse is associated with high impulsive behavior and may represent one behavioral manifestation of impulsive behavior. One predictor of substance misuse is childhood maltreatment, which is, in turn, associated with difficulty regulating unwanted emotion. Accordingly, impulsive behavior is high among individuals exposed to maltreatment and likely functions as one behavioral strategy for coping with unwanted internal experiences. Consequently, identification of behavioral processes that may account for the childhood maltreatment and impulsive behavior relation in substance misusers appears warranted. One process-based behavioral model that may be useful in this endeavor is psychological flexibility, which includes the inflexible processes of experiential …
