Proposed New Military Live Load for Highway Bridges in the United States
Get PDFThis thesis presents the results of a mathematical analysis of various live load combinations on highway bridge spans up to 304.8 meters (1,000 feet) total lengths. The analysis included continuous beams, but only the results for simple beams is presented. The analysis was performed using an independently developed Microsoft EXCEL spreadsheet computation, based on superposition and classical mechanics.
In this thesis, several actual bridge live loadings and several hypothetical live loadings were analyzed and compared to the American Association of State Highway and Transportation Officials Load and Resistance Factor Design method. Also considered was the new bridge design method adopted by the Louisiana Department of Transportation in March 2015. The evolution of bridge design loads is discussed, and the concept of the Military Load Classification is introduced and adapted to the bridge design analysis. The results of the analysis are presented, compared and interpreted for use in future bridge design
The Role of Temperamental Fear and Parenting Quality on Emerging Internalizing and Externalizing Problems During Early Childhood
Get PDFTemperamental characteristics may distinguish which children are at greater risk for later psychopathology. In addition, parenting quality may interact with the association between temperament and behavior problems to increase or decrease externalizing or internalizing behaviors in children. This study examined whether mothers’ parenting quality moderated the associations between children’s temperamental fear and children’s behavior problems. The sample consisted of 143 low-income mother-child dyads who participated in various interactional tasks designed to measure mothers’ parenting and children’s temperamental fear. While children’s fearless and fearful temperament were not significantly associated with externalizing and internalizing behaviors, respectively, some significant associations emerged. Positive and negative parenting were negatively associated, negative parenting and fearful temperament were positively associated, fearful and fearless temperament were negatively associated, and internalizing and externalizing behaviors were positively associated. Finally, results from moderation analyses indicated no significant interaction effects of parenting quality and children’s temperamental fear on children’s problem behavior
Amalgamations
Get PDFI explore time, memory, and the artist’s ability to convey experience through autobiographical photographs and drawings. In my compositions, I provide an intimate look into my life, while making wider observations about how my mind processes the world. My work is concerned with circumventing the objective, static qualities of photography. I attempt to create images that convey how experiences feel, instead of how they look through the lens of an optical apparatus. With my work, I do not wish to take from the world around me, but rather to create from the world within me. By utilizing multiple exposures and collage techniques, as well as drawings, I investigate how I experience and remember my life, and the people most important to me

Enlarged hind wings of the Neotropical butterfly Pierella helvina (Nymphalidae) enhance gliding flight performance in ground effect.
Get PDFFlight is a vital component of butterfly natural history, and flight-associated morphology is thought to be under strong selection for the performance of critical behaviors such as patrolling, courtship and oviposition. However, while different behaviors require different proportions of flapping versus gliding flight, few studies actually quantify butterfly flight behavior. Moreover, as butterfly flight is anteromotoric, no prior study has measured the role of hind wing allometry in flight. Using high-speed videography, this study compares the flight of two species of Haeterini (Nymphalidae) that regularly employ gliding flight. We also employ stereo videography and experimental hind wing area reduction to measure the effects of hind wing allometry on flight. Results suggest that although the forewings are reliable predictors of flight in these two species, relative hind wing area can significantly affect gliding flight performance, and should be considered as a factor in future investigations on flight-associated morphology in butterflies
Associations Between Community Violence Exposure, Emotional Desensitization, and Internalizing and Externalizing Symptoms: The Influence of Route of Exposure and Interpersonal Proximity to the Victims of Violence
Get PDFThe current study examines associations between community violence exposure (CVE) and internalizing and externalizing symptoms. The emotional desensitization hypothesis states that moderate levels of CVE will be associated with increased internalizing symptoms, whereas high levels of CVE will be associated with decreases in internalizing distress. The current study extends prior research by examining whether patterns of emotional desensitization differ based on the route of exposure – either being personally victimized or witnessing community violence. Further, associations examined the influence of interpersonal proximity to the victims of violence – that is, whether individuals are victims themselves (most proximal), witness violence against known individuals, or witness violence against strangers (least proximal). Participants include 714 undergraduate students (Mage = 20.5 years, SD = 3.9) who completed an online survey of CVE, internalizing and externalizing outcomes, and cognitions supporting aggression. Results revealed significant moderation by interpersonal proximity. Specifically, curvilinear associations between CVE and internalizing symptoms, reflecting emotional desensitization, were stronger at lower levels of proximity, whereas positive linear associations emerged at higher levels of proximity. Associations between CVE and more externalizing behaviors were stronger at low, compared to high, levels of proximity. Internalizing symptoms and cognitions supporting aggression partially mediated the association between CVE and externalizing behaviors. Further, latent profile analysis revealed that distinct groups of individuals were classified based on cumulative frequency of CVE and types of violent experiences. Thus, route of exposure, relationship to the victims of violence, and type of violence are each salient characteristics of CVE that may relate differentially to adjustment

How to Get a Job in Book Publishing
Get PDFThere are many different doorways into the world of book publishing and it can be challenging, but there are choices that can make it easier. Aspiring publishers often have a hard time breaking into this world because they have no guide. This thesis will be a guide to traversing the different avenues into the world of publishing. Prospective publishers, editors, and writers will be provided with a landscape of what it’s like to work in book publishing. It will also cover the two different ways that people become publishers, an overview of the basic requirements that publishing houses look for in potential employees, and the basic process of what publishers do
