    Management education holds promise for addressing deficiencies in interuniversity science, technology, engineering, and mathematics (STEM), as well as sustainability curricula. Accordingly, we designed, developed, implemented, and longitudinally evaluated interdisciplinary STEM-based curricula in the United States. Students in five sections of business management courses and two sections of STEM courses received a STEM-based sustainability intervention (i.e., an interdisciplinary STEM and sustainability module). To assess student outcomes following the intervention and examine the feasibility of cognitive mapping as a student learning assessment tool, we implemented a pre- and post-course modified cognitive mapping assessment in treatment and comparison courses. To interpret the results, we ran descriptives, correlations, paired sample t tests, and principal component analysis. The t tests suggest that when all coding categories are considered, those participating in curricular interventions listed significantly more sustainability terms. The principal component analysis results demonstrate that treatment courses improved variability explained by 7.23% between pre- and post-tests but declined by 8.22% for comparison courses. Overall, linkages became stronger between parent code categories for treatment courses and weaker for comparison courses. These findings add to existing research related to cognitive mapping and demonstrate the ability of the method to capture changes in student outcomes after exposure to STEM-based sustainability curriculum.

    Understanding public media channel preferences can inform preparedness plans, response strategies, and long-term recovery. However, questions remain about how media consumption changes across pre-crisis, crisis, and post-crisis phases. Past theories argue that media use may change for several reasons, including during times of societal conflict and challenge. These theories point to the belief that, during a crisis, we expect media channel use to change because media preferences during a crisis will be fundamentally different compared to everyday routines. This paper takes advantage of a survey fielded to Texas residents soon after Hurricane Harvey. Here we ask: (1) What media channels are most prominent in each crisis phase? and (2) Do media channel preferences change across crisis phases? We use simple descriptive statistics and chi-squares tests to describe media channel preferences across the three crisis phases by demographics. Additionally, we use alluvial diagrams to visualize media channel preferences over time. In total, 62% (n=174) of respondents reported no changes in channel preferences. However, chi-square tests identified significant differences in media use changes related to a handful of demographic characteristics. These findings are explored alongside theories that would hypothesize likely media use changes across pre-crisis, crisis, and post-crisis phases.
