This Work-In-Progress paper seeks to continue the development of a framework with which to organize engineering ethics instructional approaches. We build on a recent coding framework that was developed as part of a systematic review of US post-secondary engineering ethics education literature. We apply and iterate on the framework by analyzing the 2016 National Academy of Engineering report, “Infusing Ethics into the Development of Engineers: Exemplary Education Activities and Programs,” which includes two-page synopses of 25 exemplary ethics programs. By applying the framework to these exemplars, we aim to identify prominent instructional approaches utilized across NAE exemplars and the extentmore »

Over the past decade, the trade of counterfeit goods has increased. This has been enabled by advancements in low-cost digital printing methods (e.g., inkjet and laserjet) that are an asset for counterfeit production methods. However, each printing method produces characteristic printed features that can be used to identify not only the printing method, but also, uniquely identify the specific make and model of printer. This knowledge can be used for determination of whether or not the analyzed item is counterfeit. During the first phase of this research, chemical and physical analyses were performed on printed documents and ink samples formore »

Ethical becoming represents a novel framework for teaching engineering ethics. This framework insists on the complementarity of pragmatism, care, and virtue. The dispositional nature of the self is a central concern, as are relational considerations. However, unlike previous conceptual work, this paper introduces additional lenses for exploring ethical relationality by focusing on indebtedness, harmony, potency, and reflective thought. This paper first reviews relevant contributions in the engineering ethics literature. Then, the relational process ontology of Alfred North Whitehead is described and identified as the foundation of the ethical becoming concept. Following this, ethical becoming is imagined as comprising five components:more »

Quenching and partitioning (Q&P) processing of third-generation advanced high strength steels generates multiphase microstructures containing metastable retained austenite. Deformation-induced martensitic transformation of retained austenite improves strength and ductility by increasing instantaneous strain hardening rates. This paper explores the influence of martensitic transformation and strain hardening on tensile performance. Tensile tests were performed on steels with nominally similar compositions and microstructures (11.3 to 12.6 vol. pct retained austenite and 16.7 to 23.4 vol. pct ferrite) at 980 and 1180 MPa ultimate tensile strength levels. For each steel, tensile performance was generally consistent along different orientations in the sheet relative to themore »

Abstract Despite awareness of the mutations conferring insecticide resistance in the bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), within the United States few studies address the distribution and frequency of these. Within the United States, studies have focused on collections made along the East Coast and Midwest, documenting the occurrence of two mutations (V419L and L925I) within the voltage-gated sodium channel α-subunit gene shown to be associated with knockdown resistance (kdr) to pyrethroids. Here, the distribution and frequency of the V419L and L925I site variants is reported from infestations sampled within Oklahoma and its immediately adjacent states. Additionally, the presencemore »
