Background Calls for culture change as key to systemic reform in engineering education implicitly assume the existence of common elements of a distinctive culture. The landscape for engineering education studies that invoke the concept of culture is complex and multi‐faceted, yet still ill‐defined and incomplete. Purpose (Hypothesis) The aim of this study is to develop a conceptual framework of cultural dimensions that has the potential to guide the understanding of culture in the context of engineering education to demonstrate “where we are” and “how to get where we want to go.” Design/Method Ethnographic methods within an overarching interpretivist research paradigm were used to investigate the culture of engineering education as manifested in one institution. Adapting Schein's cultural framework, the data were collected and analyzed to distil from observable behaviors and practices the essence of the culture in the form of tacitly known cultural norms, shared assumptions, and understandings that underpinned the lived experience of staff and students. Results The findings are discussed within six cultural dimensions which emerged from the data as: An Engineering Way of Thinking, An Engineering Way of Doing, Being an Engineer, Acceptance of Difference, Relationships, and Relationship to the Environment. Conclusions The detailed findings from this study, combined with evidence from other studies, support the view that the proposed six dimensions have the potential to be transferred to other institutions as a practical tool for evaluating and positioning the culture of engineering education.

We present here the first quantum mechanical/molecular mechanics (QM/MM) studies of taurine/alpha-ketoglutarate dioxygenase (TauD) enzymes. Our studies are focused on the chemical properties of the oxo-iron species and the effect of the protein environment on its structural and electronic behavior. Although the active site region of TauD is very polar with many key hydrogen bonding interactions and salt bridges, the actual effect of the protein environment on the ordering and relative energies of the possible spin state structures is found to be quite small. Optimized geometries are very close to ones observed with density functional theory models that did not take the protein environment into consideration. The calculations show that protonation of the histidine ligands of iron is essential to reproduce the correct electronic representations of the enzyme. Hydroxylation studies of taurine by the oxo-iron active species predict that it is a very efficient catalyst that reacts with substrates via low reaction barriers.

This article aims to contribute (1) new data on verbal -s by systematically examining its behavior in Devon English (DE), a variety spoken in southwest England, and (2) a broader historical and cross-dialectal perspective for understanding the origin and function of verbal -s in nonstandard varieties of English in North America. We focus on the linguistic contexts of its occurrence from the diachronic and synchronic literature. The results show that verbal -s is conditioned by phonological, syntactic, semantic, and lexical factors. These include the few variable constraints on verbal -s attested throughout the evolution of verbal -s in the history of the English language. Moreover, DE exhibits patterns of verbal -s variability that have previously been associated with African American Vernacular English (AAVE). The detailed nature of these linguistic correspondences—not only in frequency of the features examined, but most importantly in the details of an entire set of internal linguistic factors conditioning them—reveal that verbal -s is a linguistic feature of AAVE that originated in British dialects.
