Process Calibration For Elastically Scaled 3d Printed Models Using Fused Deposition Modeling, Edgar Bernardo Mares

Mechanical and Aerospace Engineering Theses - Archive

With the increase in additive manufacturing capabilities the use of 3D printed models characterize a critical point for evaluating aerodynamic and aeroelastic properties on aircraft configuration. An experimental and computational approach beginning with elastically scaled 3D printed models enables for a case to be defined, developed, and extracted to match aeroelastic test behavior. The basis of this work is supported by aeroelastic tailoring and scaling methods in the application of 3D printed models. To accomplish this, stiffened 3D printed plates are scaled from elastically scaled 3D printed models for stiffness through geometric configurations, different build orientations, and bead thickness as …

My Eyes Have Seen Your Consolation_ Παρακλησις In Luke-Acts, Alexandre Vieira

Doctor of Philosophy Dissertation

Vieira, Alexandre Teixeira. “My Eyes Have Seen Your Consolation: Παράκλησις in Luke-Acts.” Ph.D. diss., Concordia Seminary, 2018. 216 pp.

Luke describes Simeon as a faithful Jew who was “awaiting the consolation of Israel.” Many interpreters say that this description conveys Luke’s idea that there is a separate hope for the nation of Israel, which would be made manifest at some point in the future when the Messiah would bring about political deliverance for them. Others argue that, although Luke himself did not think that was the case, Simeon and other Jews in Luke’s narrative did, but the narrative Luke writes …

Levels Of Par-1 Kinase Determine The Localization Of Bruchpilot At The Drosophila Neuromuscular Junction Synapses., Kara R. Barber, Martin Hruska, Keegan M. Bush, Jade A. Martinez, Hong Fei, Irwin B. Levitan, Matthew B. Dalva, Yogesh P. Wairkar

Farber Institute for Neuroscience Faculty Papers

Functional synaptic networks are compromised in many neurodevelopmental and neurodegenerative diseases. While the mechanisms of axonal transport and localization of synaptic vesicles and mitochondria are relatively well studied, little is known about the mechanisms that regulate the localization of proteins that localize to active zones. Recent finding suggests that mechanisms involved in transporting proteins destined to active zones are distinct from those that transport synaptic vesicles or mitochondria. Here we report that localization of BRP-an essential active zone scaffolding protein in Drosophila, depends on the precise balance of neuronal Par-1 kinase. Disruption of Par-1 levels leads to excess accumulation of …

The Effects Of Priming Patriotism On Attitudes Toward Immigrants: Do All Americans Respond To Patriotic Images The Same Way?, Norma Elizabeth Garza Reyes

Psychology Theses - Archive

Although immigrants enrich the US culture and provide intellectual and economic stimulation, there has been a rise of anti-immigration movements, making the acculturation process more difficult for the immigrant. The purpose of this thesis was to investigate how patriotism influenced negative attitudes toward immigrants, especially among individuals who were higher on right-wing authoritarianism (RWA), national identity, and/or group narcissism. This thesis study addressed these issues by priming patriotism with unpatriotic and patriotic pictures and then examining attitudes toward immigrants/immigration. This data (N = 192) linked self-reported individual difference measures (e.g., right-wing authoritarianism (RWA)) of college students that was collected prior …

Peer Relationships, Gut Microbiota, And Health In Emerging Adulthood, Erin Quinn Austin

Psychology Dissertations - Archive

Research has consistently shown that chronic stress has negative effects on overall physical and psychological wellbeing across the lifespan. The biological mechanisms through which stress exerts its effects on the body and the mind includes the recently discovered microbiome-gut-brain axis, the bidirectional communication between the brain and the enteric nervous system that is modulated by the microorganisms residing within the gastrointestinal tract. This dissertation examined the impact chronic psychosocial stress (e.g., peer victimization, daily hassles) had on gut diversity and the relative abundance specific bacterial groups in a diverse sample of emerging adults (N = 126, Mean age = 20.07). …

The Response Of Ionosphere And Thermosphere To The High Latitude Energy Deposition, Yang Lu

Physics Dissertations - Archive

The ionosphere and thermosphere are the important regions in the Earth upper atmosphere. They represent the ionized and neutral particles, respectively. The main external energy sources in those regions are solar radiation and geomagnetic energy due to the solar wind-magnetosphere interaction. The neutral particles are ionized by solar radiation on the dayside. Meanwhile, the energy deposition from the magnetosphere is also critical at high latitudes. The energy source at high latitudes depends on whether the local magnetic field line is closed or not. In the polar cap region where it is connected to open magnetic field line, the main energy …

Observed Cooking Behaviors Of Families With And Without Childhood Cancer Survivors And The Development Of A Healthy Cooking Assessment Tool, Margaret Pleta Raber

Dissertations and Theses (Open Access)

Diet is a modifiable risk factor for several cancers and other chronic diseases. Cooking skills are a target for dietary intervention, with much of the general population reporting infrequent and inadequate home preparation of meals. Childhood cancer survivors (CCS) are a population at high risk of several chronic conditions including secondary cancers that may be influenced by home cooking behaviors. We conducted observations of food preparation practices in 29 parents of healthy school-aged children and 11 parents of CCS. Observations included an audio and video recording of one evening meal per family. Parents were asked to wear a small body …

Collateral Benefits Of Diabetes Self-Management Associated With Self-Administered Outpatient Parenteral Antimicrobial Therapy, Anisha P. Ganguly

Dissertations and Theses (Open Access)

Self-administered outpatient parenteral antimicrobial therapy (S-OPAT) is a self-care treatment modality in which patients requiring extended courses of intravenous antibiotics are trained to safely self-administer treatment via an indwelling catheter in their home. Many patients seen in the S-OPAT program have a diagnosis of diabetes and present with infections associated with poor glycemic control, including skin and soft-tissue infections and osteomyelitis. Given the degree of patient activation required to successfully complete the S-OPAT process, we hypothesized that participation in this self-care program may benefit patients in self-management of other chronic health conditions, such as diabetes. The study team included Anisha …

Does Space Matter? An Investigation Of The Spatial Variation In Gestational Weight Gain Associations With Country Of Birth Among Hispanic Women And Access To Care In Texas, Christopher R. Webb

Dissertations and Theses (Open Access)

Inadequate and excess gestational weight gain (GWG) are serious, but potentially preventable adverse pregnancy outcomes which affect as many as two-thirds of pregnant women in the United States. While location and space are associated with a variety of pregnancy outcomes, limited research has investigated potential spatial variation in GWG. The goal of this research is to improve the knowledge of how spatial geography is associated with GWG through secondary analyses of 70,000 to 160,000 birth certificate registry records for Texas mothers with a live birth delivery in 2014. Specifically, this research attempts to assess whether access to obstetrics and gynecologist …

Adverse Childhood Experiences, Depression, And Resilience In African-American Adolescents, Jamie C. Freeny

Dissertations and Theses (Open Access)

Research shows that exposure to adverse childhood experiences (ACEs) is common among adolescents; however, no studies have examined the prevalence of ACEs in a racially homogenous sample of African-American adolescents. Thus, the present study examined the cumulative and individual prevalence of ACEs in African-American adolescents. Data were collected from African-American adolescents (n = 241) who attended youth events hosted by churches in Houston, TX. An expanded ACEs tool was used to collect data. ACE scores were summed and dichotomized to 0-3 ACEs versus 4-19 ACEs because a score of four or more indicates a higher risk for adverse mental and …

Development And Usability Testing Of Quit4health, A Smoking Cessation Smartphone App For Young Adults, Katarzyna Czerniak

Dissertations and Theses (Open Access)

Tobacco use is the leading cause of death in the United States. As of 2016, 23.5% of American 18-25 year olds reported having used cigarettes in the last month compared to 20.2% of adults and only 3.4% of adolescents. Due to the efficacy and widespread general use of mobile technology today, mobile-phone health, or mHealth apps, have become increasingly popular methods of delivering smoking cessation programs. However, there is a lack of evidence in regards to the quality and the effectiveness of using mHealth to deliver smoking cessation interventions to young adults. This study aims to fill this gap to …

Dissecting The Role Of The Insulin Receptor Signaling Pathway On Regenerative Organ Growth In Snakes, Kyle Alyson Chi

2018 Fall Honors Capstone Projects - Archive

The genes and regulatory activity of the Insulin Receptor Signaling Pathway are highly controlled within tissues that undergo regenerative growth. Recently, the Insulin Receptor Signaling Pathway has been implicated in driving extreme post-feeding organ growth in snakes, but its precise role in this growth remains unknown. Here, we analyzed gene expression before and after feeding in three snake species using Ingenuity Pathway Analysis (IPA) to identify which specific components of the Insulin Receptor Signaling Pathway are likely involved in regenerative growth. Genes involved with cellular stress response, transcription, and protein synthesis, such as Serum/Glucocorticoid-Regulated Kinase (SGK), Eukaryotic Translation Initiation Factor …

Understanding The Connection Between Clinically Diagnosed Adhd (Attention Deficit Hyperactivity Disorder), And/Or Depression, With Childhood Abuse/Maltreatment: A Qualitative Interpretive Meta-Synthesis, Miriam Tepper

2018 Fall Honors Capstone Projects - Archive

Attention Deficit Hyperactive Disorder (ADHD) is a chronic, neurological disorder diagnosed in children who show symptoms of inattention, and/or hyperactive/impulsive behaviors. Considering that these symptoms overlap with some symptoms of abuse and neglect, it is necessary to further explore how to differentiate. A Qualitative Interpretive Meta-Synthesis (QIMS) was conducted to synthesize results from existing qualitative studies on students who were abused or neglected. Almost 150 school-aged students and 14 agencies were included in this paper. Six major themes emerged: 1) setting the stage, 2) the unexpected role of school, 3) how it started, 4) how it ended, 5) long term …

The Relationship Between Body Composition And Fitness Parameters, Rachel Agostino

2018 Fall Honors Capstone Projects - Archive

The purpose of this research study was to investigate the relationship between body composition and fitness parameters. Seven recreationally active males, age: 20.7 ± (1.1) years, height: 183.6 ± (9.2) cm, weight: 79.2 ± (9.9) kg, volunteered for this study. Body composition, aerobic and anaerobic measurements were taken and analyzed using correlational statistics. Results indicated strong inverse correlations between body fat percentage and peak power (-0.836) and body fat percentage and mean power (-0.841). There was a weak correlation between body fat percentage and total work (0.390). Overall, the lower the body fat percentage, the more muscle mass is available …

Towards Automated Domain-Oriented Lexicon Construction And Dimension Reduction For Arabic Sentiment Analysis, Hasan A. Alshahrani

Dissertations

Sentiment analysis is a type of text mining that uses Natural Language Processing (NLP) tools to identify and label opinionated text. There are two main approaches of sentiment analysis: lexicon-based, and statistical approach. In our research, we use the lexicon-based approach because the lexicon contains sentiment words and phrases which are the main linguistic units to express sentiments. More specifically, we work with domain-oriented lexicons as they are more efficient than general ones because the polarity is heavily driven by domains.

Arabic language has a degree of uniqueness that makes it hard to be processed with the available cross-language tools …

Color-Blind Racial Ideology, Social Justice Attitudes, And Cultural Competency In U.S. Medical Students And Resident Physicians, Jennifer G. Hahm

Dissertations

Health disparities disproportionately affect the lives of racial and ethnic minorities in the United States (Agency for Healthcare Research and Quality, 2015; U.S. Department of Health and Human Services NHQR, 2013). Social conditions, social determinants, and structural inequities have been acknowledged as influential forces on minority health (Link & Phelan, 1995; World Health Organization, 2011). Focusing on eliminating environmental and social conditions affecting the health status of racial and ethnic minorities should be a prerogative for healthcare professionals in reducing health disparities. The purpose of this study is to examine the relationship between color-blind racial ideology and social justice attitudes …

Counter-Revolution And Egypt’S Lower Middle Class, Keith Glenn Whitmire

Graduate Theses and Dissertations

The Egyptian lower middle class has been declining since the 1970s. Yet since the 2011 uprising and coup d’état the lower middle class has sat in the midst of an economic and political counter-revolution carried out by the police, the military, and Egypt’s intelligence services. In particular, President Abdel Fattah al-Sisi has responded to Egypt’s economic crisis in 2014 and onward by engaging in a program of austerity has sped the decline of the Egyptian lower middle class significantly. The Egyptian lower middle class is in increasing danger of becoming merely educated working poor. Therefore this dissertation will examine the …

Retrospective: A Historiographical Aesthetic In Contemporary Singapore And Malaysia, Kian Chow Kwok

Research Collection School of Social Sciences

In an interview published a month before his passing, Hayden Whitesuggested historical studies had finally arrived at an “era of the image,” givenhow long it took for historians to recognize the potentialities of photographyand subsequently cinema and post-cinema as not just historical objects butalso modes of doing history. White cited queer history as an example ofcomplicating the binary between the object and method of historical study,enabling new approaches to understanding history and historiography(Ethan Kleinberg and Hayden White on the Practical Past, Part 2, published onYouTube, February 5, 2018).
