Nearly all software built today impinges upon end-user privacy and needs to comply with relevant regulations. Therefore, there have been increasing calls for integrating considerations of compliance with privacy regulations throughout the software engineering lifecycle. However, software engineers are typically trained in the technical fields and lack sufficient knowledge and support for sociotechnical considerations of privacy. Privacy ideation cards attempt to address this issue by making privacy compliance understandable and actionable for software developers. However, the application of privacy ideation cards in real-world software projects has not yet been systemically investigated. The effectiveness of ideation cards as a pedagogical tool has not yet been examined either. We address these gaps by studying how teams of undergraduate students applied privacy ideation cards in capstone projects that involved building real-world software for industry sponsors. We found that privacy ideation cards fostered greater consideration and understanding of the extent to which the projects aligned with privacy regulations. We identified three main themes from student discussions of privacy compliance: (i) defining personal data; (ii) assigning responsibility for privacy compliance; and (iii) determining and exercising autonomy. The results suggest that application of the cards for real-world projects requires careful consideration of intersecting factors such as the stage at which the cards are used and the autonomy available to the developers. Pedagogically, ideation cards can facilitate low-level cognitive engagement (especially the cognitive processes of meaning construction and interpretation) for specific components within a project. Higher-level cognitive processes were comparatively rare in ideation sessions. These findings provide important insight to help enhance capstone instruction and to improve privacy ideation cards to increase their impact on the privacy properties of the developed software. 

This study used radar observations and a high‐resolution numerical simulation to explore the interactions between an mesoscale convective system (MCS), cold pool outflows, and atmospheric bores in a non‐uniform baroclinic environment. The bores were generated by a nocturnal MCS that occurred on 2–3 June 2017 over the southern North China Plain. The goal of this investigation is to determine how the structure of bores varied within this non‐uniform environment and whether and how the bores would maintain the MCS and alter its structure. To the southwest of the MCS, where there was large CAPE and a well‐mixed boundary layer, discrete convection initiation occurred behind a single radar fine line (RFL) maintaining the propagation of the MCS. To the southeast of the MCS, multiple RFLs were found suggesting the generation of an undular bore in an environment containing an intense nocturnal stable boundary layer with dry upper layers and little CAPE. Hydraulic and nonlinear theory were applied to the simulation of the MCS revealing that the differences in the bore evolution depended on both the characteristics of the cold pool and the variations in the ambient environment. Thus, the characteristics of the ambient environment and the associated differences in bore structure impacted the maintenance and organization of the MCS. This study implies the importance of an accurate representation of the low‐level ambient environment and the microphysics and kinematics within the MCS to accurately simulate and forecast cold pools, the generation and evolution of bores, and their impact on nocturnal MCSs.
