The Impact Of The Model Of Black Femininity And Maternal Anxious Mother Attachment To Adolescent Black Girls' Self-Esteem, Mechell R. Guy

Doctoral Dissertations and Projects

This research was designed to explore how the traditional Model of Black Femininity stereotypes portrayal of Mammy, Sapphire, Jezebel, and Strong Black Women and maternal anxious mother attachment potentially impacts adolescent Black girls’ self-esteem. These constructs are relevant to increasing concerns regarding developing a high level of self-esteem and psychological well-being amongst adolescent Black girls. Two central questions are guided by this study. First, is the self-esteem of adolescent Black girls influenced by negative stereotypes of African American women? Secondly, would the self-esteem of adolescent Black girls correlate with maternal anxious attachment theory? Participants were twelve adolescent Black females ranging …

The Rise Of Corporate Individualism In Twenty-First Century Worship, Russell Allen Robbins

Doctoral Dissertations and Projects

Western society has experienced a monumental paradigm shift which has influenced the way in which the church worships in the twenty-first century. Postmodernism has led to an increasingly self-focused individualism in corporate worship which overvalues personal experience and undervalues the communal aspect of corporate worship. Despite much discussion concerning postmodern generations, the influence of postmodern thought upon the rise of corporate individualism in worship has yet to be examined. The purpose of this qualitative, historical study is to examine the factors that have led to the rise of corporate individualism in worship, the indications of corporate individualism in worship, and …

The Predictive Relationship Between School Climate And Self-Perceived Stress Levels Among Fourth- And Fifth-Grade Teachers, Andrea Wood Eason

Educational research continues to show that teachers are leaving the field of education in large numbers for a variety of reasons. One documented reason for teacher attrition is job-related stress. This correlational, predictive study examined the relationships between the predictor variables of school climate (collaboration, decision-making, instructional innovation, school resources, and student relations) with the criterion variable of teacher stress among fourth- and fifth-grade public school teachers from across the United States. A convenience sample of 68 teachers participated in the study by completing the Revised School Level Environment Questionnaire (R-SLEQ), which measured school climate, and the Teacher Stress Inventory …

Emotional Regulation And Treatment Progress Of Male Child And Adolescent Therapeutic Campers, Stephen Edward Talley

Doctoral Dissertations and Projects

For the past 75, years Therapeutic Camping (ThC) has been utilized as a therapeutic modality, although it has been largely unknown or unrecognized by the traditional treatment community. ThC bears similarities to wilderness therapy and was initially developed for children and youth suffering from behavioral and emotional problems. Mental and behavioral health issues are frequent in youth which can cause personal, familial, social, and economic problems. Another core underlying issues emotion dysregulation, which involves the inability to regulate emotion across multiple domains. Mental health providers have recognized the need to reduce the effects associated with emotion dysregulation and limited treatment …

The Lived Experience Of Evangelical Christian Homeschooling Fathers In Fulfilling The Biblical Role Of Disciple-Maker: A Transcendental Phenomenological Study, William Robert Farrington

Doctoral Dissertations and Projects

The purpose of this transcendental phenomenological study was to describe the lived experience of Evangelical Christian homeschooling fathers in discipling their children. The theological framework that guided this study was that of the biblical call to discipleship by Jesus Christ in Matthew 28:18-20, and how that calling applies to parenting. The theoretical framework that guided this study was the responsible fathering theory, as it focuses on the complex relationships between the father, the mother, the children, and contextual or outside influences. The central research question of the study was: How do Evangelical Christian homeschooling fathers describe the lived experience of …

Menu-Dependent Food Choices And Food Waste, Hongxing Liu, Joaquín Gómez-Miñambres, Danyi Qi

ESI Working Papers

We use a combination of randomized field experiments and online surveys to test how the menu design affects food choices and food waste. In our field experiment, participants face one of two menus: a narrow menu that only displays a small portion of food, or a broad menu that also contains bigger portions. While all options are equally available in both menus, they differ in how easy and fast the different choices can be made. Our results show that, compared to the broad menu, participants in the narrow menu ordered smaller portions of food. Importantly, food intake was similar across …

Characterization Of A Variable Diameter Bioreactor (Vdb), Zhe Su

Master's Theses and Capstones

Bioreactors for cell culture or fermentation are widely used for the production of proteins and other value-added products. Operation of bioreactors at large scale involves progressively increasing the culture volume in 4 to 10 folds increments to inoculate the culture and scale it up stepwise. To initiate the cell growth in a typical bioreactor of 20,000L, it often requires a train from benchtop scale at 1L to 10L, 100L, 1000L, 4000L and finally the 20,000L bioreactor. The transfer of cells from one bioreactor to the next one inevitably involves “lag phase” at the beginning of each culture, during which cells …

Nutrient Management Strategies For Organic Vegetable Production, Emma Jones, Daniela Barrera, Jennifer R. Reeve, Dan Drost

All Current Publications

Organic vegetable production can be profitable for growers in Utah looking to supply local markets. Much of Utah has short growing seasons (<150 days frost-free) with hot, dry summers and cold winters. Organic growers must work within these constraints to generate sufficient soil fertility using cover crops, composts, and targeted use of commercial organic fertilizers. This fact sheet explores nutrient management techniques used at the Utah State University (USU) Student Organic Farm (Student Farm) located in Cache County. In operation since 2008, the Student Farm was certified organic in 2011.

Masculinized Second-To-Fourth Digit Ratio (2d:4d Ratio) Is Associated With Lower Cortisol Response In Infant Female Rhesus Monkeys (Macaca Mulatta), Elizabeth K. Wood, Parker Jarman, Elysha Cash, Alexander Baxter, John P. Capitanio, James Dee Higley

Faculty Publications

The second-to-fourth digit ratio (2D:4D ratio) is considered a postnatal proxy measure for the degree of prenatal androgen exposure (PAE), which is the primary factor responsible for masculinizing the brain of a developing fetus. Some studies suggest that the organizational effects of PAE may extend to the hypothalamic-pituitary-adrenal (HPA) axis response to stress. This study investigates the relationship between 2D:4D ratio and HPA axis functioning using a rhesus monkey (Macaca mulatta) model. Subjects were N = 268 (180 females, 88 males) rhesus monkey infants (3–4 months of age). Plasma cortisol concentrations were assayed from two blood samples obtained …

Complex Assessment Of Relationship Quality Within Dyads, Wendy C. Birmingham, Maija Reblin, Allison A. Vaughn, Timothy W. Smith, Bert N. Uchino, Chandler M. Spahr

Faculty Publications

Higher quality relationships have been linked to improved outcomes; however, the measurement of relationship quality often ignores its complexity and the possibility of co-occurring positivity and negativity across different contexts. The goal of this study is to test the added benefit of including multiple dimensions, contexts, and perspectives of relationship quality from both individuals in predicting marital functioning. The Social Relationships Index assessed positive and negative dimensions of relationship quality under neutral, positive, and support-seeking contexts for 183 heterosexual married couples. Models showed that the inclusion of multiple dimensions of relationship quality across all three contexts improved prediction of marital …

Characterising Life In Settlements And Structures: Incorporating Faecal Lipid Biomarkers Within A Multiproxy Case Study Of A Wetland Village, H Mackay, Kl Davies, J Robertson, L Roy, Et Al

School of Geography, Earth and Environmental Sciences

Roundhouses are ubiquitous features of Iron Age landscapes across North West Europe, yet the way they were used internally is not well understood. We demonstrate how spatial analyses of steroid lipid biomarkers advances our understanding of household activities, living conditions and animal management associated with a well-preserved 5th century BCE roundhouse from Scotland's first Iron Age wetland village, Black Loch of Myrton, especially when combined with more traditional archaeological approaches. Faecal steroids (5ß-stanols and bile acids) are well preserved within the wetland roundhouse floor deposits. Diffuse faecal inputs are identified within these deposits, limiting the resolution of faecal source discrimination …

How Does Ethnicity Influence Entrepreneurship Opportunity Formation Amongst Immigrant Entrepreneurs In Dublin?, Kingsley C. Njoku

School of Medicine Publications

In recent years, replicability of neuroscientific findings, specifically those concerning correlates of morphological properties of gray matter (GM), have been subject of major scrutiny. Use of different processing pipelines and differences in their estimates of the macroscale GM may play an important role in this context. To address this issue, here, we investigated the cortical thickness estimates of three widely used pipelines. Based on analyses in two independent large-scale cohorts, we report high levels of within-pipeline reliability of the absolute cortical thickness-estimates and comparable spatial patterns of cortical thickness-estimates across all pipelines. Within each individual, absolute regional thickness differed between …

A New Era In Asthma Management: Assessment Of Asthma Control, Kevin R. Murphy, Joel Solis

School of Medicine Publications

Asthma is recognized as a chronic, heterogenous disease characterized by airway inflammation and a history of respiratory symptoms (eg, wheeze, shortness of breath, chest tightness, or cough) that vary over time and in intensity.1 Variations are often triggered by factors such as exercise, allergen or irritant exposure, change in weather, or viral respiratory tract infections. Asthma symptoms and airflow limitation may resolve spontaneously or in response to treatment. Symptoms may be absent for weeks or months, yet airway hyperresponsiveness related to chronic airway inflammation usually persists.

Faculty, Staff and Students Publications

SIGNIFICANCE: The retina is critical for vision, and several diseases may alter its biomechanical properties. However, assessing the biomechanical properties of the retina nondestructively is a challenge due to its fragile nature and location within the eye globe. Advancements in Brillouin spectroscopy have provided the means for nondestructive investigations of retina biomechanical properties.

AIM: We assessed the biomechanical properties of mouse retinas using Brillouin microscopy noninvasively and showed the potential of Brillouin microscopy to differentiate the type and layers of retinas based on stiffness.

APPROACH: We used Brillouin microscopy to quantify stiffness of fresh and paraformaldehyde (PFA)-fixed retinas. As further …

Dynamic Incorporation Of Multiple In Silico Functional Annotations Empowers Rare Variant Association Analysis Of Large Whole-Genome Sequencing Studies At Scale, Xihao Li, Zilin Li, Hufeng Zhou, Sheila M. Gaynor, Yaowu Liu, Han Chen, John Blangero, Joanne E. Curran, Michael Mahaney, Juan M. Peralta

School of Medicine Publications

Large-scale whole-genome sequencing studies have enabled the analysis of rare variants (RVs) associated with complex phenotypes. Commonly used RV association tests have limited scope to leverage variant functions. We propose STAAR (variant-set test for association using annotation information), a scalable and powerful RV association test method that effectively incorporates both variant categories and multiple complementary annotations using a dynamic weighting scheme. For the latter, we introduce 'annotation principal components', multidimensional summaries of in silico variant annotations. STAAR accounts for population structure and relatedness and is scalable for analyzing very large cohort and biobank whole-genome sequencing studies of continuous and dichotomous …

Improvement Of Cryo-Em Maps By Density Modification, Thomas C Terwilliger, Steven J Ludtke, Randy J Read, Paul D Adams, Pavel V Afonine

Faculty, Staff and Students Publications

A density-modification procedure for improving maps from single-particle electron cryogenic microscopy (cryo-EM) is presented. The theoretical basis of the method is identical to that of maximum-likelihood density modification, previously used to improve maps from macromolecular X-ray crystallography. Key differences from applications in crystallography are that the errors in Fourier coefficients are largely in the phases in crystallography but in both phases and amplitudes in cryo-EM, and that half-maps with independent errors are available in cryo-EM. These differences lead to a distinct approach for combination of information from starting maps with information obtained in the density-modification process. The density-modification procedure was …
