Description
The rise in the number of students found to have autism has been staggering over the past ten years. Accommodating these students effectively and appropriately in a public school is a challenge many teachers are deemed with, sometimes without adequate training. This study was aimed at affecting the underlying social misunderstandings inherent to students with Autism Spectrum Disorder and an at-risk general education peer through a comprehensive intervention consisting of peer mentoring, interactive social stories and video modeling strategies. Observations, student interviews, vignettes and student and researcher journals served as data sources. Three fourth grade boys, including a student with autism, a peer with behavioral concerns and a model peer, participated in an intervention designed using a multiple baseline across behaviors. The target students, including the student with autism and the peer with behavioral concerns increased their ability to demonstrate three distinctive skills, attending to task, raising hand and academic responding. Analysis of the data also showed an overall increase in levels of engagement and motivation. Strong friendships developed among all three participants. Implications suggest that a comprehensive approach is effective in reducing unwanted social behaviors and promoting positive social skills and gives further insight into the target students' motivation.

Description
Arcadia Elementary School is an urban Title 1 school that serves 800 students in kindergarten through eighth grade. The school uses a commercial program called Make Your Day to manage student behavior. This program, aligned to the tenets of Positive Behavior Interventions and Supports (PBIS), meets the needs of most students but not the most frequent classroom disruptors. This mixed methods participatory action research study explores the how an understanding of a frequently disruptive student's ecology can lead to more effective support and improved behavioral outcomes. The Behavior Intervention Team process consists of effective data tracking tools and practices and a team-based, data-driven approach to student behavior analysis and is a model for how urban schools can leverage existing resources to better support disruptive students.

Description
Effectively educating students with autism is a necessary element in providing all students with a free and appropriate public education, and as the number of students diagnosed with an autism spectrum disorder continues to increase in both public and private educational settings, providing successful and satisfactory professional development opportunities in the area of autism is becoming increasingly essential. This study explored the experiences of twenty-three educators in a suburban southwest K-12 public school district, as they participated in a fifteen-hour professional development course in an online or face-to-face format, and collaboratively problem-solved their challenges in educating students with autism. Qualitative data was collected from participants' weekly written reflections and comments from a pre- and post-survey on attitudes, to determine quality of and satisfaction with collaboration in relation to course format. Results indicated that the online format produced higher-quality collaboration when it came to presenting one's own situation(s) to the group, finding group discussions helpful, having enough time to collaborate, providing feedback/suggestions to group members, and perceiving suggestions for one's own situation as helpful (as evidenced by the number of suggestions that participants said they would likely implement). The face-to-face format produced higher-quality collaboration when it came to in-depth problem-solving regarding a situation, implementing suggestions for one's own situation, and relating course content to collaborative activities. Participants' attitudes about using technology as a means of collaboration showed little change overall from pre- to post-survey. Though slight increases in positive attitudes concerning technology were found in various areas, many participants still thought highly of a face-to-face format for collaborative purposes, even after participating in the online professional development course. Findings may be of use to educational institutions developing online or face-to-face professional development opportunities in the area of autism.

Description
Traditionally when the topic of secondary traumatic stress (STS) is discussed, it is often in regard to medical professionals and first responders. People who have STS or compassion fatigue, as it has been renamed, have been defined as people who are dealing with traumatic stress and/or emotional burdens via their “patients.” This study, conducted at a major university in the southwest, measured educators’ perceptions of the extent of their compassion fatigue using the Professional Quality of Life Scale (ProQOL) before and after a voluntary online support training during last four weeks of the semester. Educators who were full time scored better than the educators who worked part time on the three components of the Compassion Fatigue Scale. Results from this study suggest that additional training surrounding compassion fatigue may be needed in the future.

Description
Nursing school can be challenging for undergraduate students, largely because they do not know what to expect in terms of the demands of the rigorous academic program. Students who enter the program with unrealistic expectations of the demands, such as underestimated time needed for studying for exams or preparing for clinical and class time, as well as the emotional toll of time away from family and friends are often challenged with being adequately prepared for the day-to-day experience of nursing school. Once students have been in the program a few semesters, they begin to get the flow of the expectation as well as an understanding of how to manage their time. Unfortunately, if their adjustment period is not quick enough, they can academically or voluntarily withdraw due to the pressures of the demanding curriculum. In order to combat this phenomenon and give students a perspective that can assist them in their adjustment period, a Student Navigator Program (SNP) was implemented at a local community college. Data was collected from experimental and control groups using a mixed methods research design - comparing final grade percentage, performance on a standardized exam, and use of support services. The quantitative data suggest there is no statistical significance in participation in the SNP with the exception of a few select cohorts. The qualitative data suggest the SNP program is helpful at the beginning of the first semester of nursing school. Taken together, the data suggest the SNP can be helpful in the beginning of the semester for willing participants to assist with managing the unknown. Data from this study guides nursing programs as they aim to retain current nursing students through the first semester and progress through the program.

Description
Social-emotional learning (SEL) methods are beginning to receive global attention in primary school education, yet the dominant emphasis on implementing these curricula is in high-income, urbanized areas. Consequently, the unique features of developing and integrating such methods in middle- or low-income rural areas are unclear. Past studies suggest that students exposed to SEL programs show an increase in academic performance, improved ability to cope with stress, and better attitudes about themselves, others, and school, but these curricula are designed with an urban focus. The purpose of this study was to conduct a needs-based analysis to investigate components specific to a SEL curriculum contextualized to rural primary schools. A promising organization committed to rural educational development is Barefoot College, located in Tilonia, Rajasthan, India. In partnership with Barefoot, we designed an ethnographic study to identify and describe what teachers and school leaders consider the highest needs related to their students' social and emotional education. To do so, we interviewed 14 teachers and school leaders individually or in a focus group to explore their present understanding of “social-emotional learning” and the perception of their students’ social and emotional intelligence. Analysis of this data uncovered common themes among classroom behaviors and prevalent opportunities to address social and emotional well-being among students. These themes translated into the three overarching topics and eight sub-topics explored throughout the curriculum, and these opportunities guided the creation of the 21 modules within it. Through a design-based research methodology, we developed a 40-hour curriculum by implementing its various modules within seven Barefoot classrooms alongside continuous reiteration based on teacher feedback and participant observation. Through this process, we found that student engagement increased during contextualized SEL lessons as opposed to traditional methods. In addition, we found that teachers and students preferred and performed better with an activities-based approach. These findings suggest that rural educators must employ particular teaching strategies when addressing SEL, including localized content and an experiential-learning approach. Teachers reported that as their approach to SEL shifted, they began to unlock the potential to build self-aware, globally-minded students. This study concludes that social and emotional education cannot be treated in a generalized manner, as curriculum development is central to the teaching-learning process.

Description
This study focused on the connection between the EnvZ/OmpR two-component regulatory system and the iron homeostasis system in Escherichia coli, specifically how a mutant form of EnvZ11/OmpR is able to reduce the expression of fepA::lacZ, a reporter gene fusion in E. coli. FepA is one of several outer membrane siderophore receptors that allow extracellular siderophores bound to iron to enter the cells to power various biological processes. Previous studies have shown that in E. coli cells that expressed a mutant allele of envZ, called envZ11, which led to altered expression of various iron genes including down regulation of fepA::lacZ. The wild type EnvZ/OmpR system is not considered to regulate iron genes, but because these envz11 strains had downregulated fepA::lacZ, this study was undertaken to understand the connection and mechanisms of this downregulation. A large number of Lac+ revertants were obtained from the B32-2483 strain (envz11 and fepA::lacZ) and 7 Lac+ revertants that had reversion mutations not directly correcting the envZ11 allele were further characterized. With P1 phage transduction genetic mapping that involved moving a kanamycin resistance marker linked to fepA::lacZ, two Lac+ revertants were found to have their reversion mutations in the fepA promoter region, while the other five revertants had their mutations mapping outside the fepA region. These two revertants underwent DNA sequencing and found to carry two different single base pair mutations in two different locations of the fepA promoter region. Each one is in the Fur repressor binding region, but one also may have affected the Shine-Dalgarno region involved in translation initiation. All 7 reveratants underwent beta-galactosidase assays to measure fepA::lacZ expression. The two revertants that had mutations in the fepA promoter region had significantly increased fepA activity, with the revertant with the Shine-Dalgarno mutation having the most elevated fepA expression. The other 5 revertants that did not map in the fepA region had fepA expression elevated to the same level as that found in the wild type EnvZ/OmpR background. The data suggest that the negative effect of envZ11 can be overcome by multiple mechanisms, including directly correcting the envZ11 allele or changing the fepA promoter region.

Description
As part of a group project, myself and four teammates created an interactive children's storybook based off of the "Young Lady's Illustrated Primer" in Neal Stephenson's novel The Diamond Age. This electronic book is meant to be read aloud by a caregiver with their child, and is designed for reading over long distances through the use of real-time voice and video calling. While one part of the team focused on building the electronic book itself and writing the program, myself and two others wrote the story and I provided illustrations. Our Primer tells the story of a young princess named Charname (short for character name) who escapes from a tower and goes on a mission to save four companions to help her on her quest. The book is meant for reader-insertion, and teaches children problem-solving, teamwork, and critical thinking skills by presenting challenges for Princess Charname to solve. The Primer borrows techniques from modern video game design, focusing heavily on interactivity and feelings of agency through offering the child choices of how to proceed, similar to choose-your-own-adventure books. If brought to market, the medium lends itself well to expanded quests and storylines for the child to explore as they learn and grow. Additionally, resources are provided for the narrator to help create an engaging experience for the child, based off of research on parent-child cooperative reading and cooperative gameplay. The final version of the Primer included a website to run the program, a book-like computer to access the program online, and three complete story segments for the child and narrator to read together.

Description
Mammary gland development in humans during puberty involves the enlargement of breast tissue, but this is not true in non-human primates. To identify potential causes of this difference, I examined variation in substitution rates across genes related to mammary development. Genes undergoing purifying selection show slower-than-average substitution rates, while genes undergoing positive selection show faster rates. These may be related to the difference between humans and other primates. Three genes were found to be accelerated were FOXF1, IGFBP5, and ATP2B2, but only the latter one was found in humans and it seems unlikely that it would be related to the differences between mammary gland development at puberty between humans and non-human primates.

Description
Alternative polyadenylation (APA) is the biological mechanism in which the same gene can have multiple 3'untranslated region (3'UTR) isoforms due to the presence of multiple polyadenylation signal (PAS) elements within the pre mRNAs. Because APA produces mRNA transcripts that have different 3'UTR isoforms, certain transcripts may be subject to post-transcriptional regulation by regulatory non-coding RNAs, such as microRNAs or RNA binding proteins defects of which have been implicated in diseases such as cancer. Despite the increasing level of information, functional understanding of the molecular mechanisms involved in transcription is still poorly understood, nor is it clear why APA is necessary at a cell or tissue-specific level. To address these questions I wanted to develop a set of sensor strain plasmids capable of detecting cleavage and polyadenylation in vivo, inject the complete sensor strain plasmid into C. elegans and prepare stable transgenic lines, and perform proof-of-principle RNAi feeding experiments targeting genes associated with the cleavage and polyadenylation complex machinery. I demonstrated that it was possible to create a plasmid capable of detecting cleavage and polyadenylation in C. elegans; however, issues arose during the RNAi assays indicating the sensor strain plasmid was not sensitive enough to the RNAi to effectively detect in the worms. Once the problems involved with sensitivity and variability in the RNAi effects are resolved, the plasmid would be able to better address questions regarding the functional understanding of molecular mechanisms involved in transcription termination.
