Aqueous alteration processes in Jezero crater, Mars—implications for organic geochemistry

The Perseverance rover landed in Jezero crater, Mars, in February 2021. We used the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument to perform deep-ultraviolet Raman and fluorescence spectroscopy of three rocks within the crater. We identify evidence for two distinct ancient aqueous environments at different times. Reactions with liquid water formed carbonates in an olivine-rich igneous rock. A sulfate-perchlorate mixture is present in the rocks, which probably formed by later modifications of the rocks by brine. Fluorescence signatures consistent with aromatic organic compounds occur throughout these rocks and are preserved in minerals related to both aqueous environments

Three-Dimensional Point Cloud Modeling of an Intersection

Since 2010, as Service-Learning activities, students working at the Georgia Southern Built Environment and Modeling (BEaM) laboratory have generated accurate 3D models of buildings and other objects for multiple practical applications. In all cases, they used state-of-the-art, laser-based scanners and robotic total stations. In fall 2016, Civil Engineering students attending their Senior Project course completed a pro-bono project for the city of Statesboro. The successfully attained objective was a 3D virtual model of a complex street/rail-road intersection (South Main St./Fair Rd./Brannen St./two rail roads). The resulting model assists the city in redesigning the referred intersection to improve its overall safety conditions

Measuring professional identity formation early in medical school

<p><b>Aim:</b> To assess the feasibility and utility of measuring baseline professional identity formation (PIF) in a theory-based professionalism curriculum for early medical students.</p> <p><b>Methods:</b> All 132 entering students completed the professional identity essay (PIE) and the defining issues test (DIT2). Students received score reports with individualized narrative feedback and wrote a structured reflection after a large-group session in which the PIF construct was reviewed. Analysis of PIEs resulted in assignment of a full or transitional PIF stage (1–5). The DIT2 score reflects the proportion of the time students used universal ethical principles to justify a response to 6 moral dilemma cases. Students’ reflections were content analyzed.</p> <p><b>Results:</b> PIF scores were distributed across stage 2/3, stage 3, stage 3/4, and stage 4. No student scores were in stages 1, 2, 4/5, or 5. The mean DIT2 score was 53% (range 9.7?76.5%); the correlation between PIF stage and DIT score was ρ =  0.18 (<i>p</i> = 0.03). Students who took an analytic approach to the data and demonstrated both awareness that they are novices and anticipation of continued PIF tended to respond more positively to the feedback.</p> <p><b>Conclusions:</b> These PIF scores distributed similarly to novice students in other professions. Developmental-theory based PIF and moral reasoning measures are related. Students reflected on these measures in meaningful ways suggesting utility of measuring PIF scores in medical education.</p
