ABSTRACT
A Science, Technology, Engineering, Math, and Medicine (STEM+M) identity, a form of social identity, is the extent to which an individual feels accepted in the STEM+M career fields. The development of a strong STEM+M identity hinges largely on one's perceived self-efficacy in STEM+M and can be bolstered by associating STEM+M with other areas in which an individual already exhibits self-efficacy. In this study, a basketball camp served as a platform for STEM+M education in an effort to link participants' self-efficacy in basketball to STEM+M concepts where they may feel less self-efficacious. Over the first 2 years of the program, known as the Youth Sports Lab (YSL), two cohorts of underrepresented minority (URM) middle school students attended a 4-day long basketball camp hosted at Columbia University in partnership with Harlem- and Albany-based afterschool programs. The camp consisted of basketball training, jump plate fabrication, data collection, invited speakers, and group-based research projects. Our hypotheses were that participation in the program would lead to improved (1) familiarity, (2) perceived importance, and (3) interest in STEM+M. Participant responses, gathered from a 17-question Likert-scale survey administered before and after the camp, demonstrated 10 questions with significantly increased responses due to the program. The results support the conclusion that the sports-based engineering program increased STEM+M identity in the URM cohort. Future improvements to the program will include midyear student engagement and long-term follow-up.

Many challenges currently facing agriculture require long-term data on landscape-scale hydrologic responses to weather, such as from the Goodwater Creek Experimental Watershed (GCEW), located in northeastern Missouri, USA. This watershed is prone to surface runoff despite shallow slopes, as a result of a significant smectitic clay layer 30 to 50 cm deep that restricts downward flow of water and gives rise to a periodic perched water table. This paper is the first in a series that documents the database developed from GCEW. The objectives of this paper are to (i) establish the context of long-term data and the federal infrastructure that provides it, (ii) describe the GCEW/ Central Mississippi River Basin (CMRB) establishment and the geophysical and anthropogenic context, (iii) summarize in brief the collected research results published using data from within GCEW, (iv) describe the series of papers this work introduces, and (v) identify knowledge gaps and research needs. The rationale for the collection derives from converging trends in data from long-term research, integration of multiple disciplines, and increasing public awareness of increasingly larger problems. The outcome of those trends includes being selected as the CMRB site in the USDA-ARS Long-Term Agro-Ecosystem Research (LTAR) network. Research needs include quantifying watershed scale fluxes of N, P, K, sediment, and energy, accounting for fluxes involving forest, livestock, and anthropogenic sources, scaling from near-term point-scale results to increasingly long and broad scales, and considering whole-system interactions. This special section informs the scientific community about this database and provides support for its future use in research to solve natural resource problems important to US agricultural, environmental, and science policy.
