This work explores engineering ethics empirically in a "developing world" context through a framework of care ethics. Care ethics, a.k.a., the ethic(s) of care, is particularly suitable for the "developing world" context because it helps draw attention to imbalances of power (e.g., inequality, differential opportunity, and limitations on autonomy) that are often neglected by other ethical frameworks. In this work, we selected one element of care ethics (responsibility) and operationalized it in several ways: the language of responsibility; notions of paternalism; and awareness of key, influencing stakeholders. These lenses were developed and refined iteratively by employing them in case study analyses of two design project reports written by teams of senior undergraduate engineering students. Our interpretive analysis of this data outlined significant differences in care-ethical responsibility as viewed through each lens. For example, one group demonstrated little paternalism and considered several key, influencing stakeholders in their report, while the other group employed a more paternalistic approach and considered fewer key influencing stakeholders. In the interest of broadening ethical awareness in engineering, the findings and outcomes of this work can be used by educators to inform the design of course materials, exercises, and evaluation/grading criteria, such as by adapting these lenses for use in self-and/or peer-assessment. This work can also be used by researchers interested in care ethics and/or engineering student responses to issues of humanitarian or social justice nature to inform interview question and survey item design. Finally, this work contributes to the discourse of engineering ethics by developing and applying an ethical framework from the wider literature that has not received much attention in engineering ethics to date.
