Slipping on stereotypes – Interactive gender effects in the erosion of ethical behavior
Get PDFWe investigate how gender affects ethical outcomes in repeated same- or mixed-gender interactions. In our first study (N = 681), we use an experimental slippery-slope audit setting (Gino and Bazerman, 2009), in which an “auditor” makes an approval decision about the emerging unethical behavior of an “estimator” whose gender has been made salient. Based on previous evidence, unethical behavior is more likely to be accepted when it emerges gradually compared to a situation where it occurs abruptly. While we do not find a general slippery-slope effect across the whole sample, a significant slippery-slope effect is detected when the estimator is male (d = 0.36) or when the auditor is female (d = 0.27). We observe no slippery-slope effects in same-gender estimator-auditor constellations. However, in mixed-gender constellations, we find opposite effects: when male estimators are audited by females, we observe a significant slippery-slope effect (d = 0.53), driven by a high approval rate in the slippery-slope treatment. Conversely, when female estimators are audited by males, the approval rate increases in the abrupt treatment (d = 0.33). To better understand the drivers of these findings, we asked a different sample of participants (N = 90) to indicate the level of competence or honesty they attribute to male and female estimators in the estimation task. Responses suggest that the detected slippery-slope effects may be driven by auditors (especially females), attributing more competence to male estimators (d = 0.62), which is particularly relevant in the slippery-slope treatment where unethical behavior is difficult to detect. Moreover, our finding that male auditors are particularly inclined to approve overvaluations by females in the abrupt treatment, where unethical behavior becomes salient, may be driven by a more ethical assessment of female estimators (d = 0.90)
Multi-Channel Operation for the Release 2 of ETSI Cooperative Intelligent Transport Systems
Get PDFVehicles and road infrastructure are starting to be equipped with vehicle-to-everything (V2X) communication solutions to increase road safety and provide new services to drivers and passengers. In Europe, the deployment is based on a set of Release 1 standards developed by ETSI to support basic use cases for cooperative intelligent transport systems (C-ITS). For them, the capacity of a single 10 MHz channel in the ITS band at 5.9 GHz is considered sufficient. At the same time, the ITS stakeholders are working toward several advanced use cases, which imply a significant increment of data traffic and the need for multiple channels. To address this issue, ETSI has recently standardized a new multi-channel operation (MCO) concept for flexible, efficient, and future-proof use of multiple channels. This new concept is defined in a set of new specifications that represent the foundation for the future releases of C-ITS standards. The present article provides a comprehensive review of the new set of specifications, describing the main entities that extend the C-ITS architecture at the different layers of the protocol stack. In addition, the article provides representative examples that describe how these MCO standards will be used in the future and discusses some of the main open issues arising. The review and analysis of this article facilitate the understanding and motivation of the new set of Release 2 ETSI specifications for MCO and the identification of new research opportunities
