Title: EXPLORING THE INFLUENCE OF DRAMATIC ARTS ON UNDEREXAMINED LITERACIES: EXPERIENCES OF BLACK GIRLS IN AN URBAN MIDDLE SCHOOL

Location: Virtual
Abstract:

This study examined the influence of drama participation on foundational, digital, and Black Girls’ literacies of Black girls in an urban middle school. This case study used the Culturally Relevant Arts Education framework with Black Feminist Thought epistemology to address the following research questions: What are the experiences of middle school Black girls who participate in drama classes in relation to language, identity, and social media engagement? What perceptions do drama teachers have of urban middle school Black girls who participate in drama classes as they address language, identity, and social media engagement? Purposive criterion sampling was used to recruit participants for this study. Semi-structured interviews and a focus group were conducted with five Black females; four participants were middle school students who attended Stonybrook School (pseudonym), and one participant was a teacher who taught at the school. The findings of the study suggest that Black girls who participated in drama 1) Experienced enhanced foundational language, 2) Acquired a more positive racial identity, and 3) Demonstrated effective management of social media engagement. Additional findings suggest that the Black female drama teacher perceives Black middle school girls as mature enough to successfully navigate academics, identity, and social media engagement through practicing drama activities, despite the race and gender challenges they face. The findings from this study help inform educational practices, policies, and research aimed at improving outcomes for Black girls in urban middle schools.

Title: Comparative Analysis of Repeat Landscapes in Avena (Oat)

Abstract:

Avena sativa, or common oat, is a staple crop and member of the Poaceae or Grasses family. Following behind wheat, maize and rice, oats account for 10.5 million hectares of the world’s produced crops as of 2017. Phytocompounds such as β-glucan and other phytochemicals such as avenanthramides, vanillic, syringic, ferric, and caffeic acids are noted to benefit cardiovascular health or represent prospective benefactors to human health, however further investigation into these potential benefiting factors requires research that surpasses past works in breadth and scope. Much has been done to bridge the gap in resources for oats, such as the development of high throughput markers, consensus linkage maps and most recently genome sequencing efforts, however the relative complexity of cultivated oat, an allohexaploid with high similarity subgenomes, provides additional challenges to the development of these resources. A final layer of complexity is the genome size of hexaploid oats, believed to be approximately 12.8 gigabases, of which a significant portion is composed of complex repetitive elements. Characterization of these highly complex repetitive regions is difficult as repetitive regions contained within reads are characteristically difficult to map, thereby complicating assembly efforts and resulting in misassembly and gaps. Through investigation of repetitive elements by utilization of a novel pipeline capable of offering enhanced resolution and detection of repetitive elements, use of this novel information of all repetitive elements in a given genome were further examined within well-characterized Avena genomes, concluding with phylogenetic analyses examine evolutionary relationships between elements in efforts to gain insight into the of the role transposable elements across Avena, and bolster overall knowledge of the Avena family.
