ABSTRACT The initial mass and metallicity of stars both have a strong impact on their fate. Stellar axial rotation also has a strong impact on the structure and evolution of massive stars. In this study, we exploit the large grid of GENEC models, covering initial masses from 9 to 500 $${\rm M}_{\odot }$$ and metallicities ranging from $$Z=10^{-5}$$ (nearly zero) to 0.02 (supersolar), to determine the impact of rotation on their fate across cosmic times. Using the carbon–oxygen core mass and envelope composition as indicators of their fate, we predict stellar remnants, supernova engines, and spectroscopic supernova types for both rotating and non-rotating stars. We derive rates of the different supernova and remnant types considering two initial mass functions to help solve puzzles such as the absence of observed pair-instability supernovae. We find that rotation significantly alters the remnant type and supernova engine, with rotating stars favouring black hole formation at lower initial masses than their non-rotating counterparts. Additionally, we confirm the expected strong metallicity dependence of the fates with a maximum black hole mass predicted to be below 50 $${\rm M}_{\odot }$$ at SMC or higher metallicities. A pair-instability mass gap is predicted between about 90 and 150 $${\rm M}_{\odot }$$, with the most massive black holes below the gap found at the lowest metallicities. Considering the fate of massive single stars has far-reaching consequences across many different fields within astrophysics, and understanding the impact of rotation and metallicity will improve our understanding of how massive stars end their lives, and their impact on the Universe. 

In the College of Engineering, Design and Computing at the University of Colorado Denver, a faculty learning community (FLC) is exploring how to apply known pedagogical practices intended to foster equity and inclusion. Faculty come from all five departments of the college. For this three-year NSF-funded project, Year 1 was dedicated to deepening reflection as individuals and building trust as a cohort. Now, in Year 2, the FLC is focused on translating pedagogical practices from literature and other resources into particular courses. This cohort has experienced some adjustments as some faculty leave the FLC and new faculty choose to join the FLC. Since this cohort continues to grow, this paper presents key features that have supported the FLC’s formation and then transition to Year 2, as well as the design and implementation of a new faculty orientation, called the Welcome Academy, specific to new engineering faculty and practices related to diversity, equity, and inclusion. Finally, drawing on the principal investigator (PI) team’s reflections as well as feedback from external evaluators, we provide our insights with the intention of sharing useful experiences to other colleges planning to form such FLCs. 

The Urban STEM Collaboratory is a five-year project sponsored by the National Science Foundation (NSF) that addresses challenges to student success in STEM disciplines through a multi-institutional collaboration via the University of Memphis (UofM), University of Colorado Denver (CU Denver), and Indiana University--Purdue University Indianapolis (IUPUI). Study groups, tutoring, peer and faculty mentoring, and career exploration programs are being used across the three campuses to increase the participants’ commitment to a STEM field. Innovative features from Course Networking (CN) software are being deployed to provide scholars with evidence of their learning journey while expanding a meaningful academic cloud-based social network. This paper extends a previous introductory ASEE conference paper titled: “Launching the Urban STEM Collaboratory,” (Goodman et al., 2020), which outlined the initial efforts of the tri-campus collaboration. The purpose of the present paper is to summarize the impact of the project, including data analysis of effectiveness, for Year 1: 2019-2020 and Year 2: 2020-2021. Although still in progress, with the longitudinal efficacy of several of the project’s components undetermined, the project’s organizational structure, activities, and findings to date should be of value to others conducting or proposing projects with similar goals.

This Complete Evidence-Based Paper presents research about a layered peer mentorship program for undergraduate engineering students at a public urban research university and ways that students have made meaning from their mentorship experiences. This mentorship program began in Fall 2019 and has grown to include the following layers: (a) first-year students who receive mentorship, (b) sophomore- and junior-level students who serve as mentors (all of whom received mentorship during their first year), (c) junior- and senior-level students who serve as lead mentors who design the program for that academic year (including content, group meetings, service projects, meeting schedules, etc.), (d) a graduate student who mentors and supervises the lead mentors, and (e) a faculty member who oversees the overall program, provides general guidance, and advises all the students. We will describe ways in which the participating students have made meaning of their experience in the program, highlighting three key areas: (1) the web of relationships formed, which cohere into a community; (2) students’ transitions from receiving mentorship as first-year students to mentoring others in their sophomore and junior years; and (3) the feedback and iteration process by which the program has continuously developed, which forefronts student voice and agency. The paper will provide specific examples in each of the three key areas described, with a special focus on students’ own descriptions of the meaning they have made through their participation in the mentorship program. Recommendations will also be shared for those interested in implementing similar programs on their campuses.
