Adaptive Appointment Systems With Patient Preferences, Wen-Ya Wang, D. Gupta

Faculty Publications

Patients' satisfaction with an appointment system when they attempt to book a nonurgent appointment is affected by their ability to book with a doctor of choice and to book an appointment at a convenient time of day. For medical conditions requiring urgent attention, patients want quick access to a familiar physician. For such instances, it is important for clinics to have open slots that allow same-day (urgent) access. A major challenge when designing outpatient appointment systems is the difficulty of matching randomly arriving patients' booking requests with physicians' available slots in a manner that maximizes patients' satisfaction as well as …

The Effect Of Vitamin E, Selenomethionine And Sodium Selenite Supplementation In Laying Hens, Alia Aljamal

Department of Animal Science: Dissertations, Theses, and Student Research

In trial 1, 3 levels of dl-α-tocopheryl acetate (0, 50, 100 IU/kg), and 3 levels of supplemental sodium selenite (SS) (0, 0.25, 0.50 ppm), were added to a corn-soybean meal basal diet to evaluate their effects on egg quality variables, and deposition in egg yolk.  Adding 50 IU/kg dl- α-tocopheryl acetate in the diet lowered aged yolk pH.  Alpha-tocopherol in yolks increased with increasing vitamin E.  As Se level increased in the diet, yolk Se content increased.  There was a vitamin E by Se interaction affecting yolk Se content, but the highest level of Se in the yolk achieved when …

The Color(S) Of Perfection: The Feminine Body, Beauty Ideals, And Identity In Postwar America, 1945-1970, Elizabeth M. Matelski

Dissertations

Throughout the nineteenth and twentieth centuries, a number of models have existed offering women a spectrum of ideal body types and varying opinions about the role of fitness and diet in achieving these forms. In the years following World War II, prescriptive literature, Hollywood, and popular culture in general created and perpetuated the postwar feminine ideal of "the Sweater girl" - a busty, curvaceous figure more sexual than maternal. Yet, this ideal gave way in little more than a decade. In the late 1960s, youth culture placed a cult-like status on Twiggy, a model with a 31-inch bust and 32-inch …

Alternations In The Splenic Marginal Zone With Age, Shirin Z. Birjandi

Dissertations

Splenic marginal zones are architecturally organized to generate a rapid response against blood- borne antigens entering the spleen. The marginal zone is a distinct anatomical micro-environment whose main components include the marginal zone macrophages, the marginal zone B cells, the marginal zone sinus, and the metallophilic macrophages. Marginal zone macrophages, in partnership with marginal zone B cells, are particularly important in host defense against T-independent pathogens and are crucial for the prevention of diseases such as Streptococcus pneumonia. It has been widely reported that with the advancement of age there is a higher rate of mortality as a result of …

The Seduction Of Feminist Theory, Erin Amann Holliday-Karre

Dissertations

My dissertation, "The Seduction of Feminist Theory," comes out of my research on South African fiction and the Truth and Reconciliation Commission, and focuses broadly on feminist theory and the question of female power. Traditionally feminist theory has sought to empower women by insisting on their equality to men and by allowing their voices to be heard. But in trying to understand why women did not speak about their personal victimization at the TRC hearings, and why so many women characters in South African fiction are unable or unwilling to speak, I have come to see that women do not …

Education Language Policy Process In Multilingual Societies: Global Visions And Local Agendas In India, Nigeria And Unesco, Desmond I. Odugu

Dissertations

In linguistically heterogeneous societies, language planning constitutes core institutional practice for maintaining social cohesion as well as unique cultural identities. This critical sociolinguistic and comparative analysis examines education language policy process in India, Nigeria and UNESCO to understand the entrenchment of marginalizational language policies in spite of recent paradigm shifts in relevant scholarship. These include the shift from monolingualism to multilingualism as ideal for individuals and societies, perception of multilingualism no longer as a problem but a resource, heightened interrogation of ideological and political dimensionalities of language decisions in society, and an intensification of commitment to language policy and planning …

Depression In Freshmen College Students, Julie Marie Brandy

Dissertations

Adjustment to college life and attending a university for the first time can be a stressful experience for college students. Because of the challenges faced when adapting to these life changes, college students are at risk of developing depressive symptomology. The development of depressive symptoms can lead to negative life events in the lives of college students, the most significant of which is suicide. This study examined whether stress and other factors (social support and spirituality) predicted depressive symptoms and high risk behaviors in college freshmen students. In addition, the mediating role of coping on the relationship between stress and …

The Specific Role Of The Mll Cxxc Domain In Mll Fusion Protein Function, Laurie Ellen Risner

Dissertations

The MLL gene was first identified because it is involved in chromosome translocations which produce novel fusion proteins that cause leukemia. The CXXC domain of MLL is a cysteine rich DNA binding domain with specificity for binding unmethylated CpG-containing DNA. The CXXC domain is retained in oncogenic MLL fusions, and is absolutely required for the fusions to cause leukemia. This project explored the role of the CXXC domain by introducing structure-informed point mutations within the MLL CXXC domain that disrupt DNA binding, and by performing domain swap experiments in which different CXXC domains from other proteins, including DNMT1, CGBP and …

Collecting Culture In The 'Imaginary Musical Museum': General Music Textbooks 1971 - 2005, Corinne Ness

Dissertations

This study utilizes a museum lens to examine general music textbooks as a "musical museum." Through an analysis of twelve general music textbooks published between 1971 and 2005, this study examines general music textbooks as purposeful collections that reflect embedded values and assumptions that privilege Western ways of musicing. Utilizing a museum studies lens, this study examines the collection practices, collection poetics, and collection politics of the general music textbook in both a longitudinal study across historical epochs as well as a latitudinal study across grade levels and publishers. Despite a growing abundance of multicultural content in general music textbooks, …

The Role Of Nogo-A In Memory And Neuronal Plasticity In The Aged Rodent Brain, Rebecca Lynn Gillani

Dissertations

The long-term effects of stroke often include cognitive impairments, but other than cognitive rehabilitation, which is often not fully successful, there is no intervention to treat cognitive impairments in stroke survivors. Our laboratory has previously shown that immunotherapy directed against the Nogo-A protein, which is enriched on oligodendrocytes, improves recovery of skilled forelimb sensorimotor function in adult and aged rats after an ischemic stroke lesion to the sensorimotor cortex. Furthermore, this recovery was correlated with axonal sprouting from intact pathways to denervated areas, as well as dendritic sprouting and increased dendritic spine density in the contralateral sensorimotor cortex. In the …

Effects Of Neuronal Nogo-A On Properties Of Excitatory Synapses Of The Sensorimotor Cortex, Alicia Marie Case

Dissertations

Recovery after central nervous system (CNS) injury has long been a challenge for clinical investigators. Blockade of the oligodendrocyte-associated inhibitor Nogo-A has shown great promise in promoting neuronal regeneration, sprouting, and plasticity, as well as functional recovery in rodent and primate models of CNS injury. The high expression of Nogo-A in neurons of the postnatal CNS led us to look for potential roles of this protein in this stage of development. We hypothesized that postnatal, neuronal NogoA influences the density and morphology of dendritic spines in the developing CNS, in part, by regulating the maturation and stability of glutamatergic synaptic …

Effects Of Electrical Stimulation And Testosterone In Translational Models Of Facial Nerve Injury, Nijee Sharma

Dissertations

Among the various peripheral nervous system injuries seen clinically, facial nerve lesions are prevalent and have significant functional and emotional impact on patients. As injuries can occur in different segments of the facial nerve and lead to different pathophysiological outcomes, animal models that mimic the common sites of injury need to be developed so that potential therapies can be appropriately investigated. The extratemporal facial nerve axotomy model, in which the nerve is crushed at its exit from the skull, has been well established in the past and used to study the regeneration program of motoneurons. The present study uses this …

Being And Becoming A U.S. Iraq War Veteran: An Exploration Of The Social Construction Of An Emerging Identity, Anna Stachyra

Dissertations

Background: Traditional perspectives of veteran mental health are grounded in physiological and psychological principles of trauma response and recovery. An alternative perspective is needed for the provision of culturally relevant healthcare to our nation's newest veterans. Research Question: Based on the premise that each veteran cohort has a characteristically identifiable cultural form and process of cultural identification and negotiated development, the research question guiding this study was, "What is the culture of the Iraq War veteran?" Study Aim: The purpose of this study was to describe, from social constructivist perspective, Operation Iraqi Freedom [OIF] veteran cultural identity development. Study Design …

Community Assessment Of Cardiovascular Health And Risk Among People Of Mexican Descent In Berwyn, Illinois, Karen Ann Larimer

Dissertations

Background: Cardiovascular disease (CVD) is the number one cause of death in the United States and affects persons of all races and ethnicities. The number of persons of Mexican ethnicity has increased significantly in the United States, notably in the community of Berwyn, a suburb of Chicago, IL where according to the U.S. 2010 census 60% of the community is now of Mexican descent. The factors that contribute to CVD risk in persons of Mexican decent within this community must be understood before culturally appropriate risk reduction strategies are designed and implemented.

Purpose: The purpose of this community-based study is …

Study Of Stress, Housing Program Use, And Nursing Usage Among Homeless In Chicago, Henry Christian Cheung

Dissertations

Homelessness places people at risk of stressors that translate into stress and subsequently affect their health. Using Neuman Systems Model as a framework to identify modalities for nursing intervention among stressors and health problems of homeless people, this study compared stress levels among homeless people from three different homeless housing program types, investigated variables that predict the presence of stress among homeless, identified the degree of self-reported contact homeless people had with nurses, and measured to what extent nurses are preferred as health care providers by homeless people. This was accomplished through a cross-sectional, secondary data analysis of data from …

Spiritual Care In Advanced Practice Nursing, Barbara Baele Vincensi

Dissertations

Spiritual care has the potential to improve clients' health and quality of life. Since clients desire spiritual care from their health care providers as they age or as their health worsens, geriatric nurse practitioners (GNPs) were chosen to participate in this study. This cross-sectional, descriptive, survey design investigates the relationships and differences between practicing GNPs spiritual perspectives and their ability to assess clients' spiritual care needs (SCN) and provide specific spiritual care interventions (SCI). Differences and relationships were also investigated based on demographic variables of the GNPs. In addition, participants were asked to define spirituality in an open ended question. …

Marx's Concept Of The Transcendence Of Value Production, Peter Hudis

Dissertations

Although the literature produced on Marx's philosophic contribution over the past 100 years is immense, most of it has focused on his analysis of the economic and political structure of capitalism, the "materialist conception of history," and his critique of value production. There has been very little discussion or analysis, however, of his conception of what constitutes an alternative to capitalism. One reason for this is that it has long been assumed that Marx's disdain for utopian socialists and his strictures against inventing "blueprints about the future" meant that his work does not address the possible content of a postcapitalist …

Restoring The Balance: Setting Aside Naturalism In Favor Of Personhood In Extreme Cases, Brian Joseph Buckley

Dissertations

This dissertation addresses a simple question: Is an anencephalic child a person? These children are born with only a brain stem, and, as such, cannot experience any type of consciousness. If personhood is understood as an articulable moral category, particularly distinct from DNA membership, reasonable evidence would be required to attribute any such moral category in these cases. That is, to claim that children who may never think or feel are persons carries a philosophical burden that extends beyond mere Homo Sapiens membership. This dissertation accepts that burden and answers that anencephalic children are persons. To do this, I first …

Expression And Regulation Of Osteopontin In The Diabetic Heart, Abigail Goodman

Dissertations

Diabetes leads to several alterations in cardiac structure, one of which is fibrosis of the ventricular myocardium. Myocardial fibrosis is a common underlying factor in most cardiac pathologies. Osteopontin (OPN) is a small phospho-protein that has been implicated in fibrotic tissue remodeling. In the heart, the expression of OPN protein is increased after acute and chronic pathologies. Upregulation of OPN coincides with a transition to heart failure and a direct role for OPN in the progression of diabetic cardiomyopathy to heart failure has been reported.

The overall objective of this project is to determine if OPN is upregulated in the …

Challenging Client Behaviors, Coping And Burnout Among Professional Psychologists, Sasha R. Berger

Dissertations

Data from 195 psychologists who responded to the first wave of a two-wave longitudinal survey on work and family lives were used to investigate the relationship between challenging client behaviors, coping and burnout among professional psychologists. The study had four main aims: (1) defining and identifying different types of challenging client behaviors, (2) examining the link between these behaviors to the three dimensions of burnout as defined by Maslach and Jackson (1996), (3) examining the effects of coping on burnout, and (4) examining the moderating effects of coping on the relationship between challenging client behaviors and burnout.

These aims were …

Family Satisfaction, Ethnic Identity, And Subjective Well-Being Among Urban Youth, Kenia Loiret Gomez

Dissertations

Youth is a period of discovery, exploration, and instability that occurs between middle childhood and late adolescence. In the United States, a diverse society, urban youth have to clarify not only their self concept, but also their ethnic identity, which becomes part of their self-concept. Unfortunately, most researchers have ignored early adolescence (i.e., ages 12-15) and have limited their research to either childhood or later adolescence. The purpose of this study is twofold. The first part of this study examined the relationship between family satisfaction and subjective well-being (SWB) among urban youth. The second part of the study examined ethnic …

Spirituality And Physical Health: Identifying Possible Mediators Utilizing The Quadripartite Framework Of Spirituality, Meghanne Reilly Sennott

Dissertations

The purpose of this study was to further understand the relationship between spirituality and physical health. Contrary to popular assumption, spirituality and religion do not relate to physical health in the same manner. In this investigation, although religious attendance was significantly related to physical health, spirituality was not significantly associated with physical health. In fact, religious affiliation was found to moderate the relationship between spirituality and physical health. The interaction suggests that there is a positive relationship between spirituality and ill physical health for those with no religious affiliation, but no relationship between spirituality and physical health for those with …

The Effect Of Participation In Experiential Learning Programs On Personal And Civic Attitudes, Christine Inez Celio

Dissertations

Experiential learning is a general term that includes service-learning courses and academic internships. Students involved in experiential learning leave the classroom to solidify their knowledge with real-world experience. Service-learning, i.e. community service integrated into academic coursework, has become an important part of many universities' curricula. Research indicates benefits to service-learning students in self-efficacy, civic responsibility, attitudes about diversity, and attitudes about school and learning. Less is known about another type of experiential learning, academic internships, in terms of these outcomes. Experts in the experiential learning field have commented on the need for better, more frequent evaluation of experiential learning programs. …

Religion, Science, And The Conscious Self: Bio-Psychological Explanation And The Debate Between Dualism And Naturalism, Paul J. Voelker

Dissertations

This dissertation approaches metaphysical and metaethical questions concerning the nature of the human person, the existence and nature of God, and the nature of moral judgment through contemporary neuroscience, cognitive science, scientific moral psychology, and analytic philosophy of mind. Contrary to proposals that seek a harmonious integration of "religion and science" this dissertation argues that contemporary bio-psychological sciences give one ample reason to be skeptical of many of the metaphysical and metaethical claims embedded in religious traditions like Christianity and Buddhism. The first three chapters of the dissertation focus on the metaphysical issue of mind-body dualism while the fourth chapter …

Justice Across Group Boundaries: Extending Empathy-Motivated Helping To Out-Groups, Elizabeth K. Jacobs

Dissertations

This research integrates the theoretical perspectives of three separate but related areas of social-psychological research to hypothesize about relationships between the emotion of empathy and an individual's effort to extend helping behaviors to out-groups. The literatures on social justice, prosocial behavior, and group stereotypes are reviewed. An experimental study manipulated empathic concern for an out-group by varying the perspective through which participants interpret an experience that is had by a fictional immigrant group to America. In addition, the study manipulated the stereotypes that characterized the immigrant group. The effects of these independent variable manipulations on psychometric measures of empathic concern, …

Personal Beliefs And Public Print: The Influence Of Pre-Existing Attitudes And Pretrial Publicity Information On Final Verdicts, Sara Marie Locatelli

Dissertations

Pretrial publicity (PTP), defined as any news story about a case not yet in trial, has been shown to affect trial outcomes. Results, however, are mixed, with studies finding strong effects, others weaker effects, and some no effects. These differences are sometimes attributed to methodology and study stimuli. In the present research, the effect of participant attitudes was explored. Participant attitudes can have a strong influence on perceptions about a piece of information, and could explain differences in use of PTP as well as findings that judicial remedies to alleviate PTP effects are ineffective. Participants were exposed to one of …

A Systematic Review And Meta-Analysis Of The Effectiveness Of Child-Parent Interventions For Children And Adolescents With Anxiety Disorders, Kristen Brendel

Dissertations

Anxiety disorders are the most prevalent psychiatric disorders in childhood (Walkup & Ginsburg, 2002; Hirshfeld-Becker & Biederman, 2002), occuring in approximately twenty percent of the population (APA, 2000; Langley Lindsey, Bergaman & Piacentini, 2002). Children and adolescents with anxiety disorders often experience many detrimental effects such as low-self esteem, issues with social and family relationships, and a decrease in overall functioning, including academic performance. In addition, if left untreated or unrecognized, anxiety disorders in childhood often lead to more severe symptoms in adulthood including depression, substance abuse, suicidal ideation, and other comorbid anxiety disorders. Evidence suggests that anxiety disorders are …

Minority Stress Predictors Of Substance Use And Sexual Risk Behavior Among A Cohort Sample Of Men Who Have Sex With Men, Michael P. Dentato

Dissertations

This study examined the impact of factors associated with minority stress theory, including experiences of external prejudice, expectations of rejection and internalized homophobia, upon a cohort sample of men who have sex with men (MSM). Resultant associations with substance use, defined as one time use of a club drug prior to baseline; and sexual risk behavior, defined as unprotected insertive and receptive anal intercourse with primary and non-primary partners, was examined. In addition, this study compared whether each individual aspect of minority stress (external prejudice, expectations of rejection and internalized homophobia) independently or collectively predicted substance use and sexual risk …

Hope Is The Ticket To Life: Insights From Disadvantaged African American Youth, Deanna D'Amico Guthrie

Dissertations

It is important to look at strengths in populations, especially those termed "at-risk" or "disadvantaged." Hope and compassion are positive qualities inner-city African American youth can possess, and further research on these constructs with this population is needed. This exploratory, mixed methods study included both quantitative measures of hope and compassion and qualitative interviews with inner-city African American youth who are participating in an after school program. The following research questions were addressed: (1) How do the youth describe hope?, (2) How do the youth's relationships develop and maintain hope?, (3) How do the youth describe goal definition and pursuit …
