Complete Genome Sequences of Pseudomonas fluorescens Bacteriophages Isolated from Freshwater Samples in Omaha, Nebraska

The complete genome sequences of four Pseudomonas fluorescens bacteriophages, UNO-SLW1 to UNO-SLW4, isolated from freshwater samples, are 39,092 to 39,215 bp long. The genomes are highly similar (identity, \u3e0.995) but dissimilar from that of Pseudomonas phage Pf-10 (the closest relative, 0.685 to 0.686 identity), with 48 to 49 protein-coding genes and 66 regulatory sites predicted

NE STEM 4U: an out-of-school time academic program to improve achievement of socioeconomically disadvantaged youth in STEM areas

Background The Nebraska Science, Technology, Engineering, and Mathematics 4U (NE STEM 4U) program was initiated at the University of Nebraska at Omaha (UNO) in 2013. NE STEM 4U is a student-run, faculty-led program facilitating problem-based learning (PBL) sessions in science, technology, engineering, and mathematics (STEM) for socioeconomically disadvantaged kindergarten through grade 8 (K-8) students. PBL sessions are provided throughout the academic year in a twice-weekly, after-school, informal education program. The instructional material provided after school builds upon the curricula of the school day. Importantly, this program is a partnership between faculty members and administrators in higher education at UNO with community partners of Omaha including Collective for Youth, Beyond School Bells, and Omaha Public Schools. We focus on engaging K-8 youth in after-school immersion experiences in STEM fields using undergraduate students as mentors and facilitators using a model of problem-based learning. Results This program fosters an educational pipeline for students with hands-on experience in problem-solving and critical thinking. The partnerships among the community provide the foundation for success for students across the K-16 pipeline. Conclusions Herein, we describe the model of this program as documented by demonstrated successes to date in an effort to guide others in developing such a model in their city or region. We also provide models for implementation of assessment instruments

NE STEM 4U afterschool intervention leads to gains in STEM content knowledge for middle school youth

Afterschool interventions in STEM are linked to learning gains during the school day. These opportunities engage and excite students about STEM concepts since they observe a more hands-on, project-oriented approach. Often these opportunities for afterschool interventions are infrequent in nature and leave gaps for students in their maturation and understanding. Herein we describe the first report of an afterschool intervention, named NE STEM 4U, targeting socioeconomically disadvantaged middle school youth via a twice weekly, year-long intervention, studied across two years. We assessed the impact of this program on i.) short-term, individual student gains in STEM content knowledge and ii.) delivery of the program in terms of appropriateness for age group and content using the DoS observation tool. We observed statistically significant gains in STEM content knowledge over short-term assessment using a multiple-group, pre-test post-test research design comparing scores in content before and after the intervention. In this report, we highlight the impact of this nascent program in Omaha Public Schools
