How Can I Help You Today? How First-Generation Latinx/A/O Community College Students Perceive Counseling, Isaac Escoto

Dissertations

Latinx/a/o students make up almost half of the California Community College system’s population. However, Latinx/a/o students account for about 15% of three-year completion rates (certificate, degree, or transfer). In support of student success strategies, the literature describes the role of counselors and how they help students navigate the complexities of higher education. This mixed-methods study investigated how community college counseling practices and services are perceived by Latinx/a/o students; and which of those practices and services best supported the success of this student population. Key findings included the importance of counseling services, as well as preferred counseling appointment logistics and topics …

The findings in the study indicate that governing board members’ understandings of state and federal policy were not nuanced enough …

Voice Of The Inaudible: Well-Being Of Chinese American Young Adults, Chinese American Parents’ Parenting Competency, And The Correlation Of The Two, Diana Huang

Dissertations

Violence against Asian Americans since the beginning of the COVID-19 pandemic has become a national crisis in the United States. Racism against Asian Americans in the country, however, has been deep-rooted since the nineteenth century. Chinese American adolescents, who are susceptible to identity crisis as young adults and confront racial discrimination as a minority race, face distressing challenges. It is critical to inquire into their lived narratives and hear their voices. The author investigated the early life experiences of nine Chinese Americans and identified how racial identity is shaped at a young age with negative external inputs, as well as …

Influencers Of The Institution: Millennial Women Of Color On Leadership As Classified Professionals In California Community Colleges, Marisol Quevedo

Dissertations

This study centers Millennial Women of Color (MWOC) California Community College Professionals as institutional influencers by understanding how their leadership practices support the success of marginalized, minoritized, and historically underrepresented students and equity-advancing institutional change. In this study I use the term “influencer” to reflect the impact that MWOC, working as classified professionals at a CCC who are committed to serving as leaders beyond their job duties have on their students and within their institutions. The use of “influencer” in this study addresses three different areas that summarize the study’s findings. First, the theme “Key-Makers not Gatekeepers'' addresses the ways …

"A Raisin In A Box": The Experiences Of Racialized Black Males In Leadership Roles In The Non-Profit Sector In Toronto, Canada, Morris Anthony Beckford

Dissertations

Problem

The marginalization of Black and other racialized bodies (people of colour) has led to the position of a leader becoming so synonymous with Whiteness that it is normalized and naturalized; and worse, there has been limited analysis about why this is so. There is even less analysis of the experiences of the few people of colour who occupy leadership roles in organizations (Berkshire, 2008; Bradshaw et al., 2009; Mills et al., 2010; Nkomo, 2011; Ospina & Foldy, 2009). Astonishingly, organizations in diverse communities also have exiguous conversations about such salient issues like race and gender even though there is …

An Exploratory Study Of Entrepreneurial Intention Among Hispanic Entrepreneurs In Toronto, Jorge Perez Moreno

Dissertations

However, the entrepreneurial experience of Hispanic immigrants in Toronto has yet to be examined. This quantitative study examined the attitudes, norms, and perceptions influencing entrepreneurial intention and the factors that encourage self-employment continuation among immigrants in Canada.

Method

This study used a survey questionnaire of ninety-four Hispanic entrepreneurs in Toronto to comprehend their entrepreneurial intention. It examined their proficiencies, studied their business characteristics, and predicted their behavior toward self employment …

An Examination Of The Influence Of Ethnic Identity, Spirituality, And Social Support As Predictors Of Resilience Among Black Male College Graduates Born In The United States, Sandy Belizaire

Dissertations

Problem

This study aimed to assess the influence of ethnic identity, spirituality, and social support on resilience among Black males (BM) who were born in the United States of America and are recent college graduates. The achievement gap between BM and their counterparts is among education's most infuriating problems. Educators are more likely to dissuade Black men from going to college, and those who enroll drop out before they graduate (Noguera 2003; Wilborn 2013).

Method

This study employed a non-experimental, quantitative correlation research design using self-report questionnaires. The target population for this study was American-born Black males who were graduates …

Religiosity, Family Sexual Communication & Gender As Predictors Of Attitudes Toward Oral Sex Among College/University Students In The United States, Antoinette Napier

Method

Participants completed several surveys, which measured participants' personal religiosity, family sexual communication, and attitudes toward oral sex. A path analysis model was used to analyze the relationship between the proposed variables.

Results

The path analysis hypothesized model resulted in a poor fit for the data. The model was respecified by removing three items which showed weak beta weights. The respecified model produced a good fit for the data. The …

Teaching Shante Curtelia Dominique Ophelia Brown Johnson : An Autoethnography Of A Black Male, Seventh-Day Adventist, Jazz Avant-Garde Artist, Michael Gayle

Dissertations

Leadership is part and parcel of societies and cultures. Leadership research can provide understanding that in turn provides knowledge, resources and growth opportunities for leaders. Leadership may be understood from a personal perspective as being bound up with identity. As I examine myself as a person and as a leader, I realize that several identities are prominent: Black male identity, Christian identity, jazz avant-garde artistic identity. Each of those identities have features that contribute to leadership.

The purpose of this study is to describe and explore leadership experiences of a Black male, from the Seventh-day Adventist Christian tradition who is …

Predictors Of Bullying Behaviors Among Adolescents In Saudi Arabia: The Role Of Self-Esteem, Emotional Intelligence And Moral Disengagement, Ayat Hamzah

Dissertations

Problem

Bullying issues are increasing among school-age children worldwide. Children and adolescents involved in bullying as victims, perpetrators, or both are likely to experience negative consequences on their emotional, social, and academic levels (Espelage & Holt, 2001). In spite of the increasing research on bullying in Saudi Arabia, there exists gaps in the literature, especially in the role of individual traits (self-esteem, emotional intelligence) and cognitive processes (moral disengagement) on bullying behavior. Additionally, using modeling analysis to understand the predictive factors affecting bullying involvement processes also filled in some of the gaps in the literature. The current study investigated the …

Play On; Give Me Excess Of It: Intercorporeality And Musical Definitions, Abram Basil Soucy Capone

Dissertations

Philosophy of music, especially in the 20th and 21st centuries, presides over a relatively narrow range of field-specific ontological and metaphysical questions. I claim that a focus on classical music and a reliance on analogies to the plastic arts constitutes an unhelpful (but pervasive) methodology in philosophy of music, one that stands in tension with its purported aim of accurately accounting for “the ways we talk, think, and act” in relation to music and musical works (Rohrbaugh 2003, 179). While philosophers of music explicitly aim to describe praxis, a significant gap exists between existing theory and ordinary musical experiences. To …

Identification Of Conditions That Promote Biofilm Formation By Vibrio Fischeri And Elucidation Of The Underlying Signal Transduction Pathway, Courtney Noelle Dial

Dissertations

Biofilms are communities of microorganisms that have intrinsically antimicrobial properties and are difficult to treat in the clinical setting. The marine bacterium Vibrio fischeri efficiently colonizes its symbiotic squid host, Euprymna scolopes, by producing a transient biofilm dependent on the symbiosis polysaccharide (SYP), making it the perfect model system to study biofilm dynamics. In vitro, however, wild-type (WT) strain ES114 fails to form SYP – dependent biofilms. Instead, genetically engineered strains, such as those lacking the negative regulator BinK, have been developed to study SYP biofilms. Historically, V. fischeri has been grown using LBS, a complex medium containing tryptone and …

Between Script And Scripture: Performance Criticism And Mark's Character(Ization) Of The Disciples, Zechariah Eberhart

Dissertations

This project reimagines a first-century reception of the Gospel of Mark within a historically reconstructed (yet hypothetical) performance event. In particular, it considers the disciples' character and characterization through the lens of performance criticism. Questions concerning the characterization of the disciples have been relatively one-sided in New Testament scholarship, in favor of their negative characterization. This project demonstrates why such assumptions need not be necessary when we (re-)consider the oral/aural milieu in which the Gospel of Mark was first composed and received by its earliest audiences. In this project, I demonstrate that despite its "relative" newness, the primary tenets of …

Dungeons & Dragons & Dewey: Toward A Ludic Pedagogy Of Democratic Civic Life Through The Philosophy Of John Dewey And Tabletop Role-Playing Games, Susan Haarman

Dissertations

In this dissertation, which uses philosophical inquiry, I posit that tabletop role-playing games (RPGs) can provide an educative experience for democratic civic life in the Deweyan tradition. Tabletop RPGs present an invaluable resource for ongoing civic formation by encouraging deliberation and consensus building across shared goals and circumstances. Philosopher John Dewey emphasized that democracy is defined by the civic habits and collective action, not formal governance structures. The experience of playing tabletop RPGs can cultivate habitus and space for future and current citizens to practice democratic skills and commitments. Therefore, these games are a means that align with the ends …

Key Stakeholders' Perceptions Of Stem Education In Zambia: A Mixed Methods Inquiry, Choobe M. Maambo

The primary purpose of this study was to investigate key STEM stakeholders’ perceptions of STEM education in Zambia. To better understand STEM in the country, it was critical to explore the perceptions of STEM held by STEM teachers, STEM administrators, and STEM policymakers in the perception domains of STEM vision, STEM definition, STEM purpose, STEM relevance, and …

Past And Progress: Producing History At Chicago's 1933-34 World's Fair, Cate Liabraaten

Dissertations

During the country’s worst economic crisis, the Great Depression, Chicago hosted an event that presented a vision for the future. The 1933-34 Century of Progress Exposition was Chicago’s second world’s fair, important for revitalizing the local economy as well as encouraging optimism for a better future. While the fair’s theme officially focused on scientific and technological progress and was intended to be forward-looking, several exhibits dwelt on the past.

Study of these historic-themed exhibits reveals that by featuring Abraham Lincoln, Fort Dearborn, Jean Baptiste Point Du Sable, and a replica colonial village, Americans looked to their shared past to make …

None Of Us Are Safe: How Leaders Sustain Culturally Responsive Elementary And Middle School Improvement Planning, Jerry B. Michel

Dissertations

In the spring of 2020, school leaders, school boards, and teachers faced challenges beyond the COVID-19 pandemic in the United States, finding themselves under attack for the perceived applications of critical race theory in school curriculum. These conditions made active engagement in equity-focused school improvement planning more challenging. School leaders and leadership teams may benefit from using an established framework to identify strengths and areas for growth around culturally responsive pedagogy for effective school improvement planning. This article explores the use of Hammond’s (2015) Ready for Rigor Framework as a tool for identifying prioritizing which conditions for culturally responsive pedagogy …

Establishing A Health-Based Social Hierarchy, Akila Salaam Raoul

Dissertations

Social dominance theory (SDT) proposes a basic human nature to form social hierarchies based on social group membership with dominant and subordinate social groups. These social hierarchies are maintained through legitimizing myths, or beliefs that work to frame the existing social system as fair by suggesting that individuals receive the social status they deserve based on their actions and contributions to society as opposed to their group membership. The level at which an individual wants to maintain social hierarchies is indicated by their Social Dominance Orientation (SDO). SDT has been extensively studied in the context of race, gender, and age …

Characterization Of Mroq-Dependent Regulation Of Staphylococcus Aureus Quorum Sensing, Madison Ruth Stock

Dissertations

Gram-positive bacteria produce small autoinducing peptides (AIPs), which act to regulate expression of genes that promote adaptive traits including virulence. The Gram-positive pathogen Staphylococcus aureus generates a cyclic AIP that controls expression of virulence factors via the accessory gene regulatory (Agr) system. S. aureus strains belong to one of four Agr groups (I, II, III, and IV), and each group harbors allelic variants of AgrD, the precursor of AIP. In a prior screen for S. aureus virulence factors, the Alonzo lab identified MroQ, a putative peptidase. A ΔmroQ mutant closely resembled a Δagr mutant and had significant defects in AIP …

A Portrait Of The Leadership Of Women In Early Christianity: An Archaeological Study In Light Of The Historical And Socio-Cultural Contexts, Carina Prestes

Dissertations

Problem

The participation of women in the Early Christian communities is widely accepted. Nevertheless, there is no consensus on what was their role in these communities. Until now the study of women in the Early Christian communities has focused mostly in the writings of some ancient authors and a few biblical texts. These studies have been done mostly by theologians and historians. Such studies rarely take a deep look at the Greco-Roman background and at the historical, socio-cultural contexts. This contextualization can be quite fruitful and should be informed by recent archaeological discoveries of the first centuries of Christianity. Thus, …

A Comparison Of Virtual Vs. Traditional Cycling Exercise On Perceived Duration And Exercise Enjoyment, Kyle W. Reason

Dissertations

We compared perceived duration, ratings of enjoyment and RPE between virtual vs. standard cycling. Participants completed a VO2 peak test and four counterbalanced trials (two 20-min, two 40-min) one at each duration on the interactive Expresso bike (EXP) and a workload matched trial on a Velotron (VEL). Acute RPE were assessed every 5-min. Perceived duration (min) and exercise enjoyment were assessed 15-min post. No significant differences were found for perceived duration between trials (SDE 23.9 ± 8.4; SDV 27.1 ± 9.6; LDE 40.0 ± 12.1; LDV 38.9 ± 10.8). For long duration expresso (LDE) RPE-overall were significantly lower at 25, …

Improving The Stimulation Selectivity In The Human Cochlea By Strategic Selection Of The Current Return Electrode, Ozan Cakmak

Dissertations

The hearing quality provided by cochlear implants are poorly predicted by computer simulations. A realistic cochlear anatomy is crucial for the accuracy of predictions. In this study, the standard multipolar stimulation paradigms are revisited and Rattay’s Activating Function is evaluated in a finite element model of a realistic cochlear geometry that is based on µ-CT images and a commercial lead. The stimulation thresholds across the cochlear fibers were investigated for monopolar, bipolar, tripolar, and a novel (distant) bipolar electrode configuration using an active compartmental nerve model based on Schwartz-Eikhof-Frijns membrane dynamics. The results suggest that skipping of the stimulation point …
