"Proventing" Intimate Partner Violence-Related Attitudes Through Arts-Based Peace Education: A Sequential Explanatory Study Of Dancing Classrooms Alumni, Cody Wehlan

Doctor of International Conflict Management Dissertations

Research links intimate partner violence (IPV) to socialized, and often gendered, power-over attitudes that view abuse, control, and physical violence against, or by, an intimate partner as acceptable and appropriate in various contexts. While many IPV prevention programs emphasize education for reducing intimate partner violence-related attitudes (IPVA), most programs respond after violence has occurred and are often ineffective. Presenting an innovative form of proactive prevention, or “provention”, this dissertation combines arts-based peace education, youth IPV prevention, and intergroup contact theory (ICT) to outline how youth-focused social dance may effectively provent IPVA risk factors by teaching young people collaborative, power-with social …

Study On Applicability Of Flexible Gabion Revetment In Soft Soil Subgrade In Lake District, Su Weiwei, Lei Mingxuan, Liu Guotian, Zhang Liujun, Liu Junyong

Journal of China & Foreign Highway

Based on FLAC3D finite difference software, this paper conducts numerical simulations of both flexible gabion revetment structures and rigid revetment structures to compare their deformation and stress characteristics.

Therefore, we want to investigate the relationship between the spectral data and environmental differences in these lakes. …

Fight To Ignite: The Impacts Of Climate Change On Prescribed Burning In Pine Forests, Chloe Anderson

Celebrating Scholarship and Creativity Day (2018-)

Prescribed burning is a strategy that has been used to manage the health of forest ecosystems for thousands of years. While these practices have certainly evolved over time, recent impacts of climate change are threatening the future feasibility of implementing fire in forest management altogether. This ecological process is essential to restoring and maintaining a healthy forest ecosystem as fire acts as a catalyst by returning nutrients to soil and promoting healthy regrowth. Prescribed burning prepares forestlands for reforestation by destroying weeds and other competitive species so that native and fire-dependent species can reproduce. This process also lessens the fuel …

Meqtl Mapping In The Genoa Study Reveals Genetic Determinants Of Dna Methylation In African Americans, Lulu Shang, Wei Zhao, Yi Zhe Wang, Zheng Li, Jerome J Choi, Minjung Kho, Thomas H Mosley, Sharon L R Kardia, Jennifer A Smith, Xiang Zhou

Faculty, Staff and Student Publications

Identifying genetic variants that are associated with variation in DNA methylation, an analysis commonly referred to as methylation quantitative trait locus (meQTL) mapping, is an important first step towards understanding the genetic architecture underlying epigenetic variation. Most existing meQTL mapping studies have focused on individuals of European ancestry and are underrepresented in other populations, with a particular absence of large studies in populations with African ancestry. We fill this critical knowledge gap by performing a large-scale cis-meQTL mapping study in 961 African Americans from the Genetic Epidemiology Network of Arteriopathy (GENOA) study. We identify a total of 4,565,687 cis-acting meQTLs …
