Understanding The Impact Of Adolescent Attachment On Academic Success, Cristina Cortesi

Dissertations

In recent years, studies are citing an increase in adolescent mental health diagnoses and symptomotology related to AD/HD, Bipolar Disorder, Depression, Anxiety, and Conduct Disorders. While the associated behaviors may be the result of several variables, recent neurobiological studies combined with Attachment Theory have pointed to a possible link to attachment issues. Because of the developmental stage of adolescents, these behaviors have been observed in both home and school environments. Schools, in general in the United States, have been experiencing significant struggles in terms of lack of adequate educational success which prompted the implementation of legislation commonly known as No …

Just Water: A Feminist Catholic Response To The Commodification Of Water, Rachel Noelle Hart Winter

Dissertations

Any Catholic ecological ethic today that does not focus sustained attention to our worldwide water crisis is inadequate, for it fails to engage one of today's core social justice violations and neglects to offer any moral guidance for one of the human family's most pressing challenges. A responsible Catholic approach to water justice that addresses the problems stemming from a commodified view of water must be informed by ecofeminist concerns and by the Catholic social justice tradition of moral reasoning. As populations grow and water sources run dry, access to water has become a pressing ethical issue. Today, nearly one …

Investigating The Biochemical And Catalytic Properties Of Nitrile Hydratases, Salette Martinez

Dissertations

Chemical and pharmaceutical industries make extensive use of amide compounds for the manufacture of commodity chemicals (e.g., acrylamide) and drug intermediates (e.g., nicotinamide). Production of amide compounds is typically achieved by the hydration of nitrile compounds under acidic or basic conditions, high temperatures, and copper catalysts. However, the use of such chemical methods leads to the generation of unwanted by-products and toxic wastes, in addition to low product yields and high production costs. An alternative route for amide production is the use of a natural catalyst, for example nitrile hydratases (NHase, E.C. 4.2.1.84). NHase is a metalloenzyme that efficiently converts …

Mutations In Phospholamban Alter The Structure And Function Of The Calcium Atpase Regulatory Complex, Neha Abrol

Dissertations

Phospholamban (PLB) is an integral membrane protein that plays an important role in regulation of cardiac calcium handling and contractility. PLB exists as a homopentamer in the membrane, which upon deoligomerization into active monomers reversibly inhibits sarco/endoplasmic reticulum calcium ATPase (SERCA). Mutations in PLB that change the PLB monomer-pentamer equilibrium result in dysregulation of SERCA. To determine the structural and regulatory role of the C-terminal residues of PLB in the membranes of living cells, we fused fluorescent protein tags to PLB and SERCA. We then studied the effect of C-terminal alanine substitutions and truncation mutations on PLB oligomerization and SERCA …

The Role Of Spirituality/Religion As A Coping Mechanism During Treatment For Disordered Eating, David Franczyk

Dissertations

The purpose of this study was to investigate the role of spirituality/religion used as a coping mechanism during treatment for disordered eating. Given the mixed outcome results of current therapeutic and pharmacological treatment methods for disordered eating, it is important to investigate other factors which may influence the treatment process. This study evaluated the role of spirituality/religion used as a coping mechanism among 61 patients who were admitted into an eating disorder treatment program and then discharged over a period of 15 months. In this quantitative study, the Brief RCOPE measure was self-administered at admission to determine the levels of …

Re-Thinking Anthropomorphism Through A Genetic Philosophy Of Time, Carolyn Jo Love

Dissertations

In the classical Christian theological understanding, God and time are tightly interwoven (e.g. time and eternity, the Incarnation, and liturgy) and inform how we comprehend the presence and absence of the Incomprehensible in our day-to-day lives. Yet the classical Christian understanding does not take into account scientific discoveries pertaining to time and how this influences our experience of time. It is within the fabric of God and time that this dissertation will argue that the concept of time contained within contemporary genetics provides a significant and innovative way of considering the Classical Christian theological notion of the presence and absence …

Functional Importance Of Oxidative Post-Translational Modifications Of Ryanodine Receptor In Cardiac Sarcoplasmic Reticulum Ca2+ Handling During Oxidative Stress, Stefan R. Mazurek

Dissertations

Free ionic calcium (Ca2+) plays an essential role as a second messenger that initiates muscle contraction in the heart. Ryanodine receptor (RyR2) acts as the primary Sarcoplasmic Reticulum (SR) Ca2+ release channel in the heart. In the event that intracellular SR Ca2+ handling is compromised, both the contractility and electrical excitability of the heart can be altered. As a consequence, heart function may not be able to maintain the necessary cardiac output to meet the metabolic demand of the body.

Increased oxidation of RyR2 has been implicated in abnormal Ca2+ handling that promotes the onset and progression of cardiovascular disease. …

Internalization Of Race Messages Among Mixed Race Individuals, Jennifer Moulton

Dissertations

The present study used grounded theory qualitative methodology to explore mixed race individuals' experiences within specific racial socialization contexts of family, friends, community, and society, to identify messages received within these contexts. How messages influence both their understandings of mixed race identity and how they racially identify themselves was also examined. Mixed race identity development was found to follow an ecological framework, in which racial socialization messages serve as a mechanism through which experiences within contexts may be interpreted, to then inform conceptions of racial identity and identification choices. Common themes of experiences emerged within contexts, including disownments/disapproval, sibling differences, …

The Dape-Encoded N-Succinyl-L,L-Diaminopimelic Acid Desuccinylase (Dape) From Haemophilus Influenzae As A Prospective Target For The Development Of Novel Antibiotics, Anna Starus

Dissertations

The rapid emergence of bacteria that are resistant to todayfs antibiotics makes them more and more ineffective. Consequently, the need for a novel class of antibacterial agents is rapidly increasing. The importance of this project is emphasized by the emergence of several pathogenic bacterial strains that are resistant to all currently available antibiotics on the market today. One way to approach this problem is to develop drugs that target essential bacterial biosynthetic pathways. Based on bacterial genetic information, the meso]diaminopimelate (mDAP)/lysine biosynthetic pathway offers several potential anti]bacterial targets that have not been yet explored. One of these, the dapE-encoded N-succinyl-L,L-diaminopimelic …

Neuroscience And Galen: Body, Selfhood And The Materiality Of Emotions On The Early Modern Stage, Devon Wallace

Dissertations

From antiquity until the turn of the nineteenth century, temperament, mood and personality were believed to exist within, be managed by, and interact with material substance. Before the medical revolution of the late seventeenth century, early modern theories of anatomy and medicine were primarily based on the writings of Galen, who lived in the second century but was him influenced by a much older medical and philosophical tradition. In this period, the playwrights raise the same central question that now appears in so many reactions to the increasingly accepted "neurocentric" world view: "to what extent do I have an emotional …

Profiles Of Neuropsychological Functioning In Children And Adolescents With Spina Bifda, Rachel Wasserman

Dissertations

The current study examined neuropsychological performance among children with spina bifida (SB) to determine if there are distinct subgroups or "profiles" of cognitive functioning. 96 children with SB myelomeningocele (ages 8-15) completed a brief assessment battery. Hierarchical and non-hierarchical cluster analyses were used to identify and confirm a cluster solution. Hypothesized predictors of cluster membership included lesion level, number of shunt surgeries, history of seizures, age, ethnicity, socio-economic status, family stress, and family environment. Outcomes included independence, academic success, expectations for the future, and quality of life.

Ward's cluster method indicated a 3-cluster solution, and was replicated with 2 other …

Understanding The Development Of Global Leadership Competencies, Andrea L. Mcmullen Phd

Dissertations

As businesses seek to gain a competitive advantage in a rapidly evolving global marketplace and in the midst of a global talent shortage, the demand is increasing for guidance surrounding the development of global leaders. Although competency model frameworks have existed since the 1970s, the process of how an organization develops Global Leadership Competencies (GLCs) has not been well documented, particularly in new and evolving industries such as the biosciences. Furthermore, despite the time, effort, and money spent on learning and development or training programs, there are no studies that investigate employer-learner perceptions regarding the alignment of these learning programs …

Dissertations

Large scale shark population declines have been documented worldwide due to overexploitation and the lack of adequate management frameworks to conserve shark stocks. This study aimed at gaining an understanding of the national shark fishery and the trade in shark products from the United Arab Emirates (UAE). Data were collected from June 2010 to October 2012 through interviews with local fishermen, market and landing site surveys, fishery independent surveys, and stomach content analysis. Interviews with local fishermen (n=126) provided information on the fishery characteristics and established that sharks were increasingly targeted due to their high value in the global fin …

Phospholipase D- And Phosphatidic Acid-Mediated Signaling In Plant Response To Abscisic Acid And Reactive Oxygen Species, Liang Guo

Dissertations

The Arabidopsis genome has 12 phospholipase D (PLD) genes that are classified into six types, PLDα, PLDβ, PLDγ, PLDδ, PLDε, and PLDζ, based on sequence similarities, domain structures, and biochemical properties. Phosphatidic acids (PA) produced by PLDs have been identified as important lipid signaling molecules in cell growth, development, and stress responses. This study was undertaken to determine the role of PLD and PA in plant response to abscisic acid (ABA) and reactive oxygen species (ROS). The lipid mediator PA was found to interact with sphingosine kinases (SPHKs) in Arabidopsis. Two unique SPHK cDNAs were cloned and expressed. Both SPHKs …

Glycosyl Thiocarbamates As New Building Blocks For Chemical Glycosylation, Sneha Chandrashekhar Ranade

Dissertations

Having multiple functions in biological systems e.g. fertilization, blood group determination, cell growth; carbohydrates have remained attractive subjects for the study. They are also involved in various life threatening biological processes, such as viral and bacterial infections, tumor development, etc. Understanding of these involvements/interactions of carbohydrates in such critical processes is essential for the development of carbohydrate based vaccines and therapeutics. Although carbohydrates are present abundantly in nature, their isolation is cumbersome and low yielding, which is why, the synthesis of carbohydrate units has been of interest to many scientists. Efforts have been made to make these synthetic methods more …

The Evolution Of Floral Symmetry Across The Plant Order Lamiales, Jinshun Zhong

Dissertations

Bilaterally symmetrical corollas have evolved independently numerous times from radially symmetrical ancestors and are thought to represent adaptation to specific pollinators. However, evolutionary losses of bilateral symmetry have occurred sporadically in different lineages. CYC2-like and RAD-like are genes needed for the normal development of bilateral symmetry in snapdragon corollas. However, exactly how changes in the floral symmetry patterning genes correlate with the origin and loss of floral bilateral remains poorly known. To address this question, a densely sampled phylogeny of CYC2-like genes across the order Lamiales was inferred and calibrated. The expression patterns of these genes in early diverging and …

Lightning Strikes Twice: An Examination Of The Political Factors Associated With State-Level Death Sentences And Executions In The United States, 1930-2012, Ethan Christopher Amidon

Dissertations

Over the course of the last 50 years, scholars have emphasized the role that political processes play in shaping the nature of capital punishment practices. Empirical studies that have examined the relationship between political factors and capital punishment have attributed variation in the imposition of death sentences and the execution of offenders across jurisdictions in the United States to the politicization of criminal justice policies and practices and the shift in public sentiment towards more punitive ideologies that began in the 1970s. Even though historians have argued that capital punishment practices have always been shaped by political considerations, empirical research …

Elucidating The Factors That Modulate The Distribution Of Avian Haemosporida Parasites Across A Community Of Hosts, Matthew Christopher Ikaika Medeiros

Dissertations

Parasites are heterogeneously distributed across host species, host populations, and host individuals within populations. A primary aim of infectious disease ecology seeks to uncover the factors that drive this heterogeneity. At a fundamental level, host infection is determined by exposure and susceptibility to a pathogen. My dissertation explores how evolutionary and ecological forces associated with these fundamental determinates of infection shape variation in parasite host breadth and host infection status. Here, I focus on a community of vector-borne avian Haemosporida parasites among suburban birds of Chicago, IL. These parasites exhibit strong variation in their distribution among available hosts, and provide …

Exploring The Local And Regional Effects Of Plant Diversity On Plant Herbivore Interactions, Diego Salazar

Dissertations

The study of biological diversity and its effects on ecosystem functioning and species interactions has always been a fundamental part of biology. The accelerating loss of species in conjunction with an increasing change in the natural environment has underlined the importance of the role that biodiversity has on the evolutionary and ecological dynamics of natural systems. In this dissertation I explore the effect of local and regional patterns of plant diversity in plant-herbivore interactions. Furthermore, this work goes beyond the classical concepts of taxonomical diversity and investigates the role of phylogenetic and chemical diversity on plant-herbivore interactions. In chapter one …

Investigating The Relation Between Moral Self-Enhancement And Self-Deception: A Cross-Cultural Study Of U.S. And Chinese College Students, Ying Liu

Dissertations

Testing an evolutionary framework, this study examined moral self-enhancement in relation to self-deception and self-construal in a cross-cultural context. The participants included 127 U.S. and 107 Chinese college students. The results demonstrated that moral self-enhancement is not a characteristic unique to individualistic ideology but rather a universal motivation. Regardless of their cultural groups and self-construal, participants tended to morally self-enhance, rating their own character and sense of responsibility significantly higher than those of other people. In addition, U.S. participants were more likely to morally self-enhance compared to their Chinese counterparts. At the individual level, strong independents demonstrated greater moral self-enhancement …

The Effects Of Standards-Based Grading On Student Performance In Algebra 2, Rachel Beth Rosales

Dissertations

The use of standards-based grading in American public schools is increasing, offering students, parents, and teachers a new way of measuring and communicating about student achievement and performance. Parents indicate an appreciation for this method of grading, and students at the elementary grades (K-6) have improved standardized test scores in reading and math as a result of its implementation. This study seeks to determine whether standards-based grading has the same effect on students at the high school level (grades 9-12) by comparing end-of-course test scores and posttest scores of Algebra 2 students enrolled in a standards-based graded classroom with to …

Connecting The Dots: Understanding Migration In The Context Of Other Periods Of The Annual Cycle, Kristina Lee Paxton

Dissertations

Migration is a fundamental characteristic of the life history of many organisms. Large-scale seasonal movements expose migratory species to an array of differing environmental conditions such that the ecology, behavior, and life history strategies of migratory species must balance selection pressures associated with each phase of the annual cycle. Therefore, scientists increasingly realize that to understand the ecology of a migratory species in any one phase of the annual cycle requires an understanding of how other phases may interact with and influence the period of interest. That said, following individuals throughout the year poses a serious challenge.

The focus of …

From Script To Screen To Syllabus: The Path To Curriculum Design For Undergraduate Film Production Programs, Peter J. Muir

Dissertations

Nothing has impacted western society more than media. Tibetan spiritual leader, the Dali Lama, wrote that “film and television, newspapers, books and radio together have an influence over individuals that was unimagined a hundred years ago.” The responsibility of creating these cultural artifacts, particularly within motion picture production, is a delicate balance between artistic vision and craft-oriented vocation; the contemplative mind skills of a wise citizen with the functional hand skills of a tradesperson. Undergraduate film production education provides the best avenue for development of this duality. However, within these programs, little is known regarding how curriculum is fashioned and …
