Exponentially growing publication rates are increasingly problematic for interdisciplinary fields like Critical Zone (CZ) science. How does one “keep up” across different, but related fields with unique hypotheses, field techniques, and models? By surveying CZ academics in the Western US, a region with substantial CZ research, we document the challenge. While conventional knowledge synthesis products-particularly review papers clearly support knowledge transfer, they are static and limited in scope. More informal paths for knowledge transfer, including social networking at conferences and academic mentorship, are useful but are unstructured and problematic for young scientists or others who may not have access to these resources. While new machine-learning tools, including ChatGPT, offer new ways forward for knowledge synthesis, we argue that they do not necessarily solve the problem of information overload in CZ Science. Instead, we argue that what we need is a community driven, machine aided knowledge tool that evolves and connects, but preserves the richness of detail found in peer-reviewed papers. The platform would be designed by CZ scientists, machine-aided and built on the strengths of people-driven synthesis. By involving the scientist in the design of this tool, it will better reflect the practice of CZ science-including hypothesis generation, testing across different time and space scales and in different time periods and locations, and, importantly, the use and evaluation of multiple, often sophisticated methods including fieldwork, remote sensing, and modeling. We seek a platform design that increases the findability and accessibility of current working knowledge while communicating the CZ science practice.

Expanding the Spatial Reach and Human Impacts of Critical Zone Science
Two major barriers hinder the holistic understanding of subsurface critical zone (CZ) evolution and its impacts: (a) an inability to measure, define, and share information and (b) a societal structure that inhibits inclusivity and creativity. In contrast to the aboveground portion of the CZ, which is visible and measurable, the bottom boundary is difficult to access and quantify. In the context of these barriers, we aim to expand the spatial reach of the CZ by highlighting existing and effective tools for research as well as the “human reach” of CZ science by expanding who performs such science and who it benefits. We do so by exploring the diversity of vocabularies and techniques used in relevant disciplines, defining terminology, and prioritizing research questions that can be addressed. Specifically, we explore geochemical, geomorphological, geophysical, and ecological measurements and modeling tools to estimate CZ base and thickness. We also outline the importance of and approaches to developing a diverse CZ workforce that looks like and harnesses the creativity of the society it serves, addressing historical legacies of exclusion. Looking forward, we suggest that to grow CZ science, we must broaden the physical spaces studied and their relationships with inhabitants, measure the “deep” CZ and make data accessible, and address the bottlenecks of scaling and data‐model integration. What is needed—and what we have tried to outline—are common and fundamental structures that can be applied anywhere and used by the diversity of researchers involved in investigating and recording CZ processes from a myriad of perspectives.

Creativity has been shown to improve student learning and retention and is also one of the top skills wanted by employers in computing. However, it is seldom a clear component for most computing courses and is difficult to measure as a course outcome. This paper describes a course specifically designed for student retention with creativity as the central component, and a research study that investigated students’ perspectives on what creativity is, how it pertains to them based on a set of twelve traits, and how this course has impacted their creativity. Students indicated that this course was the most creative course that they have taken and our data shows that it influenced their self-reported creativity. Out of the traits we provided, open-minded and curious were the two selected by our students as top characteristics of creativity. We discuss our observations from this study and provide a qualitative analysis.more » « less

This research paper studies barriers to students continuing in undergraduate computing programs. On the journey to a computing profession, every course has the potential to be an off-ramp away from students’ goals. Every student who leaves a computing degree has a last class they took before not continuing, and a reason they didn’t continue. Based on qualitative analysis of open-ended questions in surveys of students in eight undergraduate computer science and engineering (CSE) courses, we identify common barriers students anticipate, and learn what encourages them to persist onto the next CSE course. For example, even for students within the major, a commonly reported barrier was the perceived inability to enroll in their next computing course due to unclear enrollment systems and requirements. We disaggregate the data by three demographic categories—race/ethnicity, gender, and admissions-type—to understand potential disparate impacts of CSE majors at our large, research- intensive university. Solutions to the reported barriers faced by students may include student-focused interventions, policy and programmatic changes at the department level, and broader institutional or external support.

The analysis of the gender dynamics in scientific research and respective outputs is crucial for ensuring that science policy is inclusive and equitable. Similar to other research outputs such as publications and patents, open source software (OSS) projects are also developed by contributors from universities, government research institutions, and nonprofits, in addition to businesses. Despite its reach and continued rapid growth, reliable and comprehensive survey data on OSS does not exist, limiting insights into contributions by gender and policy- makers’ ability to assess trends in gender representation. Like in scientific research, the inclusion of diverse perspectives in software development enhances creativity and problem-solving. Using GitHub data, researchers have found positive correlations between gender diversity of an OSS development team and its productivity (Vasilescu et al., 2015; Ortu et al., 2017). Yet there is evidence of gender bias, with women facing higher standards to have their contributions accepted (Terrell et al., 2017; Imtiaz et al., 2019). This exploratory study aims to quantify gender differences in development and use (impact) of OSS using publicly available information collected from GitHub. We focus on software packages developed for programming language R, with the majority of contributors from academia. The paper asks (1) what are gender differences in the volume of contributions? (2) has gender representation shifted over time? (3) is there a correlation between the gender of contributors and the impact of a package?more » « less

Abstract Critical Zone (CZ) scientists have advanced understanding of Earth's surface through process‐based research that quantifies water, energy, and mass fluxes in predominantly undisturbed systems. However, the CZ is being increasingly altered by humans through climate and land use change. Expanding the scope of CZ science to include both human‐ and non‐human controls on the CZ is important for understanding anthropogenic impacts to Earth's surface processes and ecosystem services. Here, we share perspectives from predominantly U.S.‐based, early career CZ scientists centered around broadening the scope of CZ science to focus on societally relevant science through a transdisciplinary science framework. We call for increased training on transdisciplinary methods and collaboration opportunities across disciplines and with stakeholders to foster a scientific community that values transdisciplinary science alongside physical science. Here, we build on existing transdisciplinary research frameworks by highlighting the need for institutional support to include and educate graduate students throughout the research processes. We also call for graduate‐student‐led initiatives to increase their own exposure to transdisciplinary science through activities such as transdisciplinary‐focused seminars and symposiums, volunteering with local conservation groups, and participating in internships outside academia.more » « less
