Emature: Intergenerational Networks In Digital Media Spaces, Andras Lukacs

Dissertations

While the literature on adolescent usage of the Internet and mobile communication technology is burgeoning, the technological affordance of increased intergenerational contacts and intergenerational friendships received less attention. This project documents how intergenerational virtual networks operate in one particular massively multiplayer online game (World of Warcraft) from the standpoint of adolescent players. Online social worlds are similar to offline settings in a lot of ways. Users must obey certain behavioral standards and follow established rules and moral codes to participate. Despite accounts of online democracy and networked individualism, control and authority is central to the functioning of these environments. Power-relationships …

Scribal Harmonization In Greek Manuscripts Of The Synoptic Gospels From The Second To The Fifth Century, Cambry Pardee

Dissertations

Harmonization in manuscripts of the Synoptic Gospels (Matthew, Mark, and Luke) has been recognized as a textual phenomenon since at least the late second century. This dissertation constitutes the first major catalogue of assimilated readings and provides evidence for the nature of harmonization in the earliest period of the development of the text of the New Testament.

Harmonization occurs whenever a scribe copying a Gospel by hand introduces a textual variant that reflects the influence of parallel material from another Gospel or gospel tradition. The body of this dissertation is a text-critical analysis of every harmonizing variant in the forty-four …

Development Of "Inside-Out" Pegylated Crosslinked Hemoglobin Polymers: Novel Hemoglobin-Based Oxygen Carriers (Hboc), Kyle Douglas Webster

Dissertations

The development of an effective blood substitute is urgent due to increasingly common blood shortages, the need to type-match donated blood, and communicable diseases (e.g. HIV) posing risks for blood transfusions around the world. There have been many attempts at creating hemoglobin-based oxygen carriers (HBOC) using a variety of techniques centered around the use of polyethylene glycol (PEG) conjugated to hemoglobin (Hb) tetramers. A novel method, “Inside-Out” PEGylation, has been developed by our lab to produce a polyethylene glycol crosslinked hemoglobin (PEG XL-Hb) polymer. This method utilizes a single PEG backbone that is surrounded by multiple proteins, instead of covering …

Expectations And Quality Of Life During The Antepartum And Postpartum Period, Mary Kathryn Adams

Dissertations

During pregnancy, women frequently anticipate birth and motherhood with unrealistic images and expectations which are formed by personal experience and society’s portrayal of motherhood (e.g., books and movies). How these expectations impact the postpartum period for women has not been well studied. However, research has identified a link between maternal expectations, reality, and negative emotional responses. When expectations are met, the experience of motherhood may be a positive one. However, when these expectations are not met, the potential for negative emotional responses may be greater. The postpartum period is a significant period of adjustment, and depression occurs in about 13%–19% …

Performance Of Individuals And Teams On Cryptographic Tasks: Factors That Affect The Consideration Of Alternative Strategies, Joseph Bihary

Dissertations

The two studies presented here examined factors that might affect teams’ and individuals’ tendency to follow outside advice when attempting to solve a complex problem known as letters-to-numbers. Past research on group dynamics suggests that a lack of group consensus or homogeneity reduces group members’ confidence in their group’s abilities, and may lead members both to seek and accept advice from outside the group. Study 1 experimentally manipulated group diversity in task performance strategies in order to investigate whether dyads whose members have divergent perspectives are more likely than homogeneous dyads to consider and use a problem-solving strategy presented from …

Cardiac Calcium Atpase Dimerization Measured By Fluorescence Resonance Energy Transfer And Chemical Cross-Linking, Daniel Blackwell

Dissertations

The cardiac sarco/endoplasmic reticulum calcium ATPase (SERCA) establishes the intracellular calcium gradient across the sarcoplasmic reticulum membrane. It has been proposed that SERCA forms homo-oligomers that increase the catalytic rate of calcium transport. We investigated SERCA oligomerization in rabbit left ventricular myocytes using a photoactivatable cross-linker. Western blotting of cross-linked SERCA revealed higher molecular weight species consistent with SERCA oligomerization. Fluorescence resonance energy transfer (FRET) measurements in cells transiently transfected with fluorescently-labeled SERCA2a revealed that SERCA readily forms homo-dimers. These dimers formed in the absence or presence of the SERCA regulatory partner, phospholamban (PLB) and were unaltered by PLB phosphorylation …

Earthly Destruction: Catholic Social Teaching, War, And The Environment, Daniel Cosacchi

Dissertations

For more than 1700 years in Christian theology, there has been a chasm between just war thinking and pacifism. Advocates of these two ideological positions have attempted to bridge this divide in a number of ways through the centuries. Some, such as Glen Stassen, have brought together thinkers on both sides of the divide to propose a just peacemaking theory. Others, such as Michael Schuck, Mark Allman, and Tobias Winright, have added new stages to just war thinking in order to make that existing tradition more robust. Some groups may identify as contingent pacifists. These would generally accept the criteria …

Kant, The Natural Law, And The Question Of Normativity In Catholic Ethics, John Robert Crowley-Buck

Dissertations

This dissertation explores the question of normativity in 21st century Catholic ethical reflection. While, today, the natural law tradition frames and founds the normative question in Catholic ethics in terms of the imago Dei, this project explores the moral philosophy of Immanuel Kant and the challenge it presents to the natural law's claim to normativity. Specifically, this dissertation argues that in Kant's ethics, the normative question is answered in terms of the dignity of humanity, rather than the imago Dei, and that the dignity of humanity is a more relevant, shareable, and normative grounding for ethical reflection. To this end, …

Dating Violence Prevention Through A Change In Gender Norms, Katie Doud

Dissertations

Gender norms that promote male dominance and control lead to greater violence against females and deleterious health effects for males (Reed, Raj, Miller & Silverman, 2010). A strict adherence to female gender roles is associated with a greater likelihood to be in an abusive relationship and a greater length of time to leave an abusive relationship (Molidar & Tollman, 1998). Adolescence is a developmental time where boys and girls rigidly follow gender stereotypes (Alfieri, Ruble, & Higgins, 1996). Three-fourths of adolescents have been in a dating relationship by their senior year in high school (Carver et al., 2003). The combination …

Evaluating The Impact Of Integrative Mental Health Treatment In Veterans With Post-Traumatic Stress Disorder, Bella Etingen

Dissertations

High numbers of US Veterans experience post-traumatic stress disorder (PTSD), but, many do not subsequently seek mental healthcare. Integrated mental health (IMH) models of treatment bring mental health professionals into the primary care setting, allowing Veterans to receive comprehensive treatment during primary care visits. The IMH treatment model may bridge the gap for Veterans with PTSD who need care and those who actually receive it. This study examined the impact that IMH has on Veterans with PTSD receiving care from VA. Using several methods of data collection (medical chart reviews, VA administrative databases, a mailed survey of patient perception of …

A Higher Law: Transatlantic Revolution And Antislavery Radicalism In Early America, 1760-1800, Anthony Di Lorenzo

Dissertations

During the Age of Revolution, abolitionist ideas interacted with notions of liberty, independence, and equality. Although slavery often served as a metaphor, in opposition to freedom, it also had tangible meanings for the enslaved. This study traces the development of revolutionary beliefs that connected reformers and abolitionists across the Atlantic world, as well as the rise of conservative ideologies that divided them. Democratic politics, religious enthusiasm, and abolitionism converged in the late eighteenth century, with significant implications for antislavery efforts. The French Revolution, in particular, represented the culmination of radical Enlightenment ideals and emboldened democrats in the United States, contributing …

Remains To Be Seen: Execution And Embodiment In The Early English Atlantic World, Erin M. Feichtinger

Dissertations

This dissertation explores the development of capitalism in the early English Atlantic World (1580 - 1752) and the manipulation of the legal system to criminalize the laboring body in order to more fully exploit the productive output of labor.

Dreamers And The College Dream: A Case Study Analysis Examining The Influences Of High Schools And High School Agents, Aliza Joy Gilbert

Dissertations

This dissertation study contributes to a nascent field of research on undocumented students and college access. Rooted in a conceptual framework of models of college choice, this study utilizes case study methodology to examine how a high school and its agents influence an undocumented student’s college choice process. The unit of analysis is a suburban public high school located in the Midwest.

Data collection included semi-structured interviews of students, teachers, counselors, and college counselors, observation of college counseling programs, and document review of college related materials. The constant comparative method was the primary system of data analysis. The coding process …

Social Skills In Youth With Spina Bifida: A Longitudinal Multimethod Investigation Of Bio-Neuropsychosocial Predictors, Christina Ehrman Holbein

Dissertations

Objective: Despite research documenting social dysfunction in youth with spina bifida (SB), little is known about the etiology of these social difficulties; most investigations identifying predictors of social deficits have concentrated exclusively on one domain. This longitudinal study examines the relative predictive power of neurocognitive (attention and executive function), family (cohesion and conflict), and health-related (body mass index, condition severity) variables on later social skills in youth with SB.

Methods: 112 youth with SB (T1 mean age = 11.19 years) and their families participated in study visits two years apart. Study variables were assessed by multiple methods (questionnaire, medical chart …

Development Of Folate Directed, Protein Based Photodynamic Therapy Agents, Rojenia Jones

Dissertations

To attack cancer cells in a specific manner, we have developed a folate-targeted, photodynamic therapy (PDT) agent. The folate (FA) and the chlorin e6 (Ce6) photosensitizer were attached to bovine serum albumin (BSA) using carbodiimide chemistry. Since over 50% of cancers overexpress folate receptors, FA-BSA-Ce6 can be taken up by them and is an effective PDT agent. Hela cells exposed to FA-BSA-Ce6 in the dark showed no cytotoxicity. Upon exposure to light, the conjugate was dose (time and concentration) dependent. Concentrations less than or equal to 2 µM were not effective at killing Hela cells but concentrations of at 5 …

You're Kind Of Just Conditioned: Women And Female College Students' Defiance Of Dominant Social Messages In The Development Of Leader Self-Efficacy, Shannon Darracott Howes

Dissertations

Researchers have consistently found that women have lower leader self-efficacy (LSE) than men, despite being equally capable as leaders. This is problematic because LSE is associated with many benefits that support the development and enactment of leadership. Despite the importance of LSE, there is a dearth of research on the construct, particularly in the higher education context. This grounded theory study utilized semi-structured interviews with 12 undergraduate students who identified as females or women to explore how they developed LSE. Findings were related with four core concepts that were woven throughout the various categories of themes that comprised the grounded …

Moral Distress And The Health Care Organization, Andy Kondrat

Dissertations

A health care professional may experience moral distress when she believes she knows the ethical course of action in a given situation, but is unable to enact that plan, or must do otherwise. This dissertation argues that health care organizations have an ethical obligation to address moral distress in their health care professionals, and that common responses to moral distress are ethically insufficient due to their reliance on hierarchical solutions when hierarchies are, in fact, often a cause of moral distress. Thus, health care organizations, as moral agents, have a responsibility to find a non-hierarchical response to moral distress.

In …

Cognitive And Neural Correlates Of Coping And Resilience In Depression, Catherine Lee

Dissertations

Depression is one of the most prevalent and devastating psychological disorders, often with a chronic or remitting/reoccurring course. The inability to effectively cope with stress and negative life events has been strongly linked to the development and maintenance of depression symptoms; yet, the cognitive and biological processes underlying the complex and multidimensional behavioral construct of coping are not well understood. Using a combination of self-report measures, computerized cognitive tasks, and scalp electroencephalography (EEG) methodologies, the present study investigated associations between specific executive function abilities (i.e., inhibition and set-shifting), underlying neural activity, coping strategy and flexibility, and depression symptoms. Results did …

Collaborative Community Prevention: An Ecological Approach To Mental Health Support For Children In Rural America, Adria Casey Mcpherson

Dissertations

There exists a dearth of research literature devoted to informing mental health practice in rural areas. However, what little research that does exist surrounding children’s mental wellness in rural places describes mental health programs as being smaller, under-served versions of their urban counterparts (National Association for Rural Mental Health, 2001). Mental health collaboration in rural areas is a clear need and an ongoing challenge. This study aims to address these concerns by reviewing relevant theories, analyzing one rural community’s mental health needs, and identifying next steps in mental health service delivery for this community.

Additional research surrounding the mental health …

The Best Poor Man's Country?: William Penn, Quakers, And Unfree Labor In Atlantic Pennsylvania, Peter B. Kotowski

Dissertations

William Penn’s writings famously emphasized notions of egalitarianism, just governance, and moderation in economic pursuits. Twentieth-century scholars took Penn’s rhetoric at his word and interpreted colonial Pennsylvania as nothing less than “the best poor man’s country,” as reflected in the title of one of the most popular histories of the colony. They also imagined a world where all men had access to economic opportunity and lived free from the barbarity endemic to Atlantic world colonies. Despite this halcyon vision of the Peaceable Kingdom, the reality was the opposite: a colony where religious convictions justified what we today (and radicals then) …

Community Violence Exposure Among Urban African American Males: Understanding The “Buffering Effect” Of Adaptive Social Support Coping On Psychosocial Outcomes, Cynthia L. Pierre

Dissertations

The current study explored the moderating roles of support coping and support

quality in the predictive relationship between community violence exposure (ECV) and a

variety of psychosocial outcomes. Participants were 119 African American males (9 th –

12 th grade; mean age at baseline = 15.33). Participants completed measures of exposure to

violence, support-seeking coping, quality of support from friends and family, and a range

of psychosocial outcomes, and completed these same measures approximately one year

after baseline. Regression analyses were conducted to examine the relationships between

ECV and psychosocial outcomes, as well as the relationships between support coping and …

Symbolic Centers In The Background Or Units At The Forefront Of Change? Race Specific Cultural Centers And Student Support Programs And Their Potential Impact On Students Of Color, William Rodriguez

Dissertations

This study examined the potential impact race specific cultural centers and student support programs (CCSSPs) have on the leadership development of students of color. Data from the Multi-Institutional Study of Leadership was used to answer two primary questions. The two primary questions focused on the potential impact of CCSSPs on leadership outcomes and the rates of participation in high-impact leadership practices. The analytic approach utilized “effect size” methodology while also conducting sample t-tests to compare means between CCSSP users and non-users and chi-square analysis for relationships between dependent categorical variables.

No findings emerged for leadership outcomes for the sample as …

Changing Medical Education: Early Efforts To Integrate Women's Health Into Education And Training, Mary Katherine Rojek

Dissertations

This is an historical study about the development of women’s health curricula in medical education across the U.S. between 1983 and 2004, a period of a great deal of innovation. At that time, some physicians, medical educators, policy makers, and government officials became aware that most U.S. medical school curricula did not address women’s health in a comprehensive manner and did not attend to many problems that were the primary causes of mortality and morbidity in women. In addition, medical research and medical education were based on a normative male model. Studies of medical education indicate that medical schools are …

Exploring The Relationships Between Spiritual Well-Being, Team Regard And Turnover Intention Of Hospice Social Workers: The Mediating Role Of Job Satisfaction, Kimberly Lynn Sangster

Dissertations

According to the US census bureau there are approximately 15,500,000 million Americans over the age of 65 years in 2015. As the population ages and prepares to die, people will need access to quality hospice and end-of-life care. Key to delivery of quality care is experienced hospice social workers. Multiple regression and mediation analysis were applied to explain the path relationships involving the variables of spiritual well-being, an innovative operationalization of the concept of team regard, job satisfaction and turnover intentions of hospice social workers in Medicare-certified hospice programs in the state of Illinois. Other variables in this study included …

Social Learning Of Employee Engagement, Swati Sharma Srivastava

Dissertations

The influence of coworkers on workplace attitudes and behaviors is a well-researched and established occurrence in organizational psychology. Given that many of these relationships may be bi-directional, Social Learning theory is a fitting lens to examine these connections. One construct that consistently surfaces as a prominent topic in organizational research is employee engagement. The aim of this research was to investigate how social learning theory may be applied to the relationship between engagement levels of role models and observing employees. Results revealed some truly validating insights, primarily confirming the influence of coworkers on employee engagement. Model type (i.e., manager vs. …

“I Am Because We Are”: A Portrait Of Trans* Postsecondary Educators’ Experiences In Higher Education, Symone L. Simmons

Dissertations

Within higher education, trans* students have become more visible and advocacy for them important. To support these claims, scholars have conducted research and produced literature on trans* college students’ identity development and experiences on campuses. However, the lived experiences of trans* educators working in colleges and universities are missing from the literature, consequently from the minds of scholars, practitioners, and administrators alike. Trans* educators experiences are important because they contribute to shifts in higher education conversations around supporting and affirming trans* people on campus. Trans* educators are mentors, advisors, and role-models, teachers, and advocates, and perhaps knowing their journey and …

Retrospective Pre/Posttest Design And Response-Shift Bias In An Urban After-School Program For Teens: A Mixed Methods Study, Jill Young

Dissertations

Evaluators need more design options to meet the challenges they face in detecting change or growth. Researchers have offered the retrospective pretest/posttest design as a remedy to curb response-shift bias and better estimate program effects, but few studies have used this approach with youth. After School Matters, a Chicago nonprofit that provides after-school programs to teens tested the retrospective pretest/posttest design using a mixed methods design to determine whether response-shift bias exists. My study provided several findings. First, though my quantitative analysis did not indicate response-shift bias was as prevalent as literature would indicate, my qualitative findings indicated that response-shift …

The Relation Of Exposure To Community Violence To Self- Efficacy Based On Neighborhood, Family, And School Effects In A Community Sample Of Latino-American Youth, Arie Zakaryan

Dissertations

Community violence is considered a “public health epidemic” in the US. Latino youth and families are a burgeoning population in the United States, and many of whom live in neighborhoods exposed to community violence. Multiple contexts should be assessed identifying developmental assets youth use to adjust positively when exposed to violence. This study examines how different environmental contexts, i.e., home, school, neighborhood and acculturation, influence the relationship between exposure to community violence and self-efficacy for Latino youth. The current study uses an archival dataset of a larger longitudinal study (Project on Human Development in Chicago Neighborhoods). A confirmatory factor analysis …

A Game Industry Beyond Diversity: Systemic Barriers To Participation In South Korea, Florence M. Chee

School of Communication: Faculty Publications and Other Works

Digital gaming has become a prominent part of mainstream culture. However, as one may observe in the public exhibitions of this form of play, the multitude of reasons for participation in the games industry are especially divided along gender lines. This paper is an analysis of themes emerging from the critical ethnographic examination of South Korea’s1 online game culture that, upon closer and iterative analyses, point to additional socioeconomic complications and systemic barriers to women’s equitable participation in the game development and production. Using South Korea’s national context as a point of reference, the findings from this case study offer …
