Book Review: The Road Back to You: An Enneagram Journey to Self-Discovery
Over the last few years, the self-assessment tool known as the Enneagram has blossomed among the college student leaders at our Christian college. One of its values has been to encourage greater self-understanding and awareness as well as a growing sense of empathy for others. The Enneagram has been particularly valuable in helping students discern how they work and play with others
Analysing the SML97 Definition: Lexicalisation
The specification of the syntax and semantics for Standard ML have been designed to support the generation of a compiler front end, but actual implementations have required significant modification to the specification. Since the specification was written there have been major advances in the development of language analysis systems that can handle general syntax specifications. We are revisiting the SML specification to consider to what extent, using modern tooling, it can be implemented exactly as originally written. In this short paper we focus on the lexical specification
Beyond iron: non-classical biological functions of bacterial siderophores
Bacteria secrete small molecules known as siderophores to acquire iron from their surroundings. For over 60 years, investigations into the bioinorganic chemistry of these molecules, including fundamental coordination chemistry studies, have provided insight into the crucial role that siderophores play in bacterial iron homeostasis. The importance of understanding the fundamental chemistry underlying bacterial life has been highlighted evermore in recent years because of the emergence of antibiotic-resistant bacteria and the need to prevent the global rise of these superbugs. Increasing reports of siderophores functioning in capacities other than iron transport have appeared recently, but reports of ânon-classicalâ siderophore functions have long paralleled those of iron transport. One particular non-classical function of these iron chelators, namely antibiotic activity, was documented before the role of siderophores in iron transport was established. In this Perspective, we present an exposition of past and current work into non-classical functions of siderophores and highlight the directions in which we anticipate that this research is headed. Examples include the ability of siderophores to function as zincophores, chalkophores, and metallophores for a variety of other metals, sequester heavy metal toxins, transport boron, act as signalling molecules, regulate oxidative stress, and provide antibacterial activity.National Institutes of Health (U.S.) (R21 A1101784
Public pedagogy and representations of higher education in popular film: New ground for the scholarship of teaching and learning
Constructions of teaching, learning, and the university within popular culture can exert an important influence on public understandings of higher education, including those held by faculty and students. As such, they constitute a rich site of inquiry for the scholarship of teaching and learning. Drawing on the notion of film as âpublic pedagogy,â this article analyses representations of higher education within 11 top grossing and/or critically acclaimed films released in 2014. We identify three broad themes across these textsâthe purpose of higher education, relationships between students and professors, and the creation of academic identitiesâand consider the implications and functions of these representational patterns for teaching, learning, and SoTL. Particular attention is given to the difference between the framing of science and arts and humanities disciplines, and to how this might resonate with the contemporary âcrisis of the humanities.
Modular grammar specification
We establish a semantics for building grammars from a modularised specification in which modules are able to delete productions from imported nonterminals. Modules have import lists of nonterminals; some or all of an imported nonterminal's productions may be suppressed at import time. There are two basic import mechanisms which (a) reference or (b) clone an imported nonterminal's productions. One of our goals is to allow a precise answer to the question: âwhat character level language does this grammar generateâ in the face of difficult issues such as the mutual embedding of languages that have different whitespace and commenting conventions. Our technique is to automatically generate a character level grammar from grammars written at token level in the conventional way; the grammar is constructed from modules each of which may have its own whitespace convention.
