Project description:Setting students on a path to success in careers in science is a challenge in poor rural Appalachian public schools. Students face many socioeconomic obstacles. Their teachers are also limited by many factors including inadequate facilities, under-funding, geographical isolation of the schools, and state-testing constraints. Additionally, students and teachers lack the availability of outside science educational opportunities. In an effort to address this situation, 24 academically strong high school junior girls and their teachers from the Carter County School System in rural east Tennessee were invited for a laboratory day at Milligan College, a small liberal arts college in the heart of the county. Science faculty, female science majors, and admissions staff volunteered in service to the project. The event included three laboratory sessions, lunch in the college cafeteria, and campus tours. This successful example, as evidenced by positive evaluations by the invited girls and their teachers, of educational outreach by a local, small liberal arts college to a rural county school system provides a model for establishing a relationship between higher education institutions and these underprivileged schools, with the intention of drawing more of these poor, rural Appalachian students, particularly girls, into a science, technology, engineering, and mathematics (STEM) career path.

Project description:Biostatisticians with advanced degrees are highly sought after. Employment opportunities in the fields of mathematics and statistics are expected to increase dramatically by 2028. Underrepresentation of minorities in biostatistics has been a persistent problem, yielding a demographic landscape that differs substantially from the general US population. In some instances, students may have the appropriate quantitative skills, but are unaware of biostatistics and in other instances, students may not yet have the appropriate quantitative background, but are intellectually capable and willing to shore up those skills once they learn about biostatistics as a viable, exciting career option. Therefore, in order to ensure robust scientific advancement, there must be a concerted effort to increase the pipeline of intellectually talented persons available with exposure to the appropriate quantitative skills who are interested in careers in biostatistics. The overarching goal of this paper is to discuss the development, implementation, and impact of a federally funded pipeline initiative aimed at increasing the number of underrepresented minorities successful in graduate training and professional careers in biostatistics as well as establishing effective mentoring and networking relationships. Our findings provide a roadmap for the development of sustainable initiatives to promote diversity in biostatistics and STEM fields more broadly.
Project description:STEM education has been considered foundational to economic growth by many countries. It has received great attention from various educational systems, but the actual implementation has triggered several problems, especially in developing countries in Asia. This qualitative study investigated the challenges to STEM education in public high schools in Vietnam. The participants were ten experienced teachers from ten different schools in a Vietnamese central province. The data were collected from in-depth semi-structured interviews. Analysis of the transcripts of the interview recordings showed that the teachers faced many challenges regarding their interdisciplinary knowledge and teaching methods, curriculum, practical constraints, and beliefs about effective STEM education. Notably, the findings concerning the teachers' beliefs about effective STEM education and the tension between their beliefs and the teaching goals were closely related to the local cultural values and the expectations of the schooling system. The findings of the study were discussed in relation to the local contextual factors and cultural values. Implications for teacher pedagogy and professional development regarding STEM education for Vietnamese high school contexts, and beyond, are discussed.
Project description:The United States has experienced a tragic increase in school shootings in recent years. Despite substantial media attention being paid to such incidents and widespread support for stricter gun control measures, substantial legislative action remains absent, however. To make sense of this puzzle, this paper focuses on the mobilizing responses of gun rights supporters in the aftermath of such events. Using granular data from 225,000 donations to the NRA's political action committee in a difference-in-differences design, this study provides causal estimates showing substantial increases in both donation amounts and donor numbers after school shootings. These results provide insight into the counter-mobilizing responses of the pro-gun political right after shootings. In contrast to the typically transient nature of gun control movements, these counter-mobilizing responses are notably durable. The results of this study have important implications for our understanding of the complexities of, and obstacles to, gun regulation in the United States.
Project description:MotivationHigh-throughput sequencing technologies are used increasingly not only in viral genomics research but also in clinical surveillance and diagnostics. These technologies facilitate the assessment of the genetic diversity in intra-host virus populations, which affects transmission, virulence and pathogenesis of viral infections. However, there are two major challenges in analysing viral diversity. First, amplification and sequencing errors confound the identification of true biological variants, and second, the large data volumes represent computational limitations.ResultsTo support viral high-throughput sequencing studies, we developed V-pipe, a bioinformatics pipeline combining various state-of-the-art statistical models and computational tools for automated end-to-end analyses of raw sequencing reads. V-pipe supports quality control, read mapping and alignment, low-frequency mutation calling, and inference of viral haplotypes. For generating high-quality read alignments, we developed a novel method, called ngshmmalign, based on profile hidden Markov models and tailored to small and highly diverse viral genomes. V-pipe also includes benchmarking functionality providing a standardized environment for comparative evaluations of different pipeline configurations. We demonstrate this capability by assessing the impact of three different read aligners (Bowtie 2, BWA MEM, ngshmmalign) and two different variant callers (LoFreq, ShoRAH) on the performance of calling single-nucleotide variants in intra-host virus populations. V-pipe supports various pipeline configurations and is implemented in a modular fashion to facilitate adaptations to the continuously changing technology landscape.Availabilityand implementationV-pipe is freely available at https://github.com/cbg-ethz/V-pipe.Supplementary informationSupplementary data are available at Bioinformatics online.
Project description:Shortage of school psychologists in the USA jeopardizes the capacity of schools to meet the needs of struggling students. The aim of the study was to evaluate the progression of school psychologists through the professional preparation—to practice pipeline for attracting, preparing, and retaining school psychologists. Descriptive research methods were used to retrospectively track three annual cohorts of graduate students from eight school psychology programs as they progressed through key milestones in their preparation and early professional practice. The results indicate that a large percentage of students completed their graduate program and continued to work in the field 1-, 3-, and 5-year post-internship for a sample that was predominately White and female. The implications of the study reinforce previous calls for graduate programs to engage in targeted, personalized efforts for recruiting graduate students with minoritized cultural identities to better meet the needs of students from culturally and linguistically diverse backgrounds.
Project description:With a rising demand for a college degree and an increasingly complicated college search, application, and selection process, there are a number of interventions designed to ease the college-going process for adolescents and their families. One such intervention, the College Ambition Program (CAP), is specifically designed to be a whole-school intervention that comprehensively connects several important aspects of the college-going process and specifically is focused on increasing interest in science, technology, engineering, and math (STEM). With many adolescents having interest in STEM careers but lacking knowledge of how to transform these interests into plans, CAP supports students in developing and pursuing their educational and occupational goals. CAP offers students tutoring and mentoring, course-counseling and advising, assistance through the financial aid process, and college experiences through visits to college campuses. In addition to these four core components, CAP is also pursuing how to integrate mobile technology and texting to further provide students with tailored resources and information about the college-going process. This chapter describes the complexities of the college-going process, the components of the CAP intervention, and presents findings that demonstrate that these strategies can increase college-going rates and interest in STEM. The authors highlight the importance of developing a college-going culture within high schools that support the alignment of postsecondary and career goals.
