More morphostasis than morphogenesis? The ‘dual professionalism’ of English Further Education workshop tutors

An international repositioning of vocational teachers in relation to knowledge and the workplace is reflected in English Further Education through the terminology of ‘dual professionalism’. Particularly in settings most closely linked to specific occupations, this discourse privileges occupational expertise that vocational educators bring from their former employment alongside pedagogic expectations of the teaching role. In a qualitative study of recently qualified teachers employed substantially in workshop settings, using the analytical framework of Margaret Archer, workplace skills and generic attributes provided a basis for claims to expertise, extending to a custodianship of former occupations. Further augmentation of educator roles, however, appeared constrained by market approaches to development and employment insecurity in the sector and beyond. In Archer’s terms, the current environment appears to cast ‘dual professionalism’ as morphostasis, drawing on former practice at the expense of teacher identity in the face of insecurity. Morphogenesis into enhanced professional teacher identities, for example, developing coherent vocational pedagogies informed by research into advances in knowledge, appears the less likely outcome in the current and emerging sector.     

One Hundred Strong: A Colloquium on Transforming Natural History Museums in the Twenty‐first Century

In February 2012, the Smithsonian's National Museum of Natural History (NMNH) convened 100 colleagues from 43 organizations to initiate a collaborative learning research agenda focused on examining important areas for innovation to better serve twenty‐first‐century audiences. The conference organizers anticipated that scientists, educators, exhibit professionals, and other members of the natural history community would identify and prioritize research questions about what, how, why, when, and where people learn about natural history. We prepared to engage in a conversation about how natural history museums could change what they do. The participants' overwhelming passion for their work, and for natural history museums and their transformative potential for society, quickly turned the conversation toward how natural history museums should change what they are. The result was an emergent learning research agenda situated within a broader vision for natural history museums.     

Value Chain Adjustments in Educational Publishing

This paper looks at at the impacts and implications of new technology for educational publishing in the context of major growth in e-Learning. Although it acknowledges the continuing influence of textbooks both on how emerging technologies will drive changes to courses and the pace at which courses evolve, the major focus is upon the impact of technological and organisational change upon the value chains for e-Learning and educational publishing. It reviews relevant developments in technology, e-Learning and educational publishing and the connections between them, using recent examples. Fundamental to the nexus between technology, e-Learning and publishing is the search for value and for new means of creating and leveraging value in a turbulent higher education marketplace. The subjective nature of value is recognised in the context of different stakeholders. The paper then links changing perceptions of value to a perceived shift within educational publishing, which entails moving from the more or less homogeneous delivery of packaged content towards the provision of truly customised learning services combining use of the latest technologies with access to high quality content. The kinds of value, old and new, provided by educational publishers are compared in a table. This shift in value is then explained in the context of value chains for e-Learning and for educational publishing. So far as educational publishing is concern there are signs of both disintermediation and reintermediation in the value chain. Amidst these changes, the position of educational publishing appears set to improve through its potential to provide a new range of integrated technology and content services.     

Multiphysics extension to physically based analyses of pipes with emphasis on frost actions

Pipes, especially buried pipes, in cold regions generally experience a rash of failures during cold weather snaps. However, the existing heuristic models are unable to explain the basic processes involving frost actions. This is because the frost action is not a direct load but one that causes variations in pipe-soil interactions resulting from the coupled thermohydro-mechanical process in soils. This paper developed and implemented a holistic multiphysics simulation model for freezing soils and extended it to the analysis of pipe-soil systems. The theoretical framework was implemented to analyze both static and dynamic responses of buried pipes subjected to frost actions. The multiphysics simulations reproduced phenomena commonly observed during frost actions, e.g., ice fringe advancement and an increase in the internal stress of pipes. The influences of important design factors, i.e., buried depth and overburden pressure, on pipe responses were simulated. A fatigue cracking criterion was utilized to predict the crack initialization under the joint effects of frost and dynamic traffic loads. The frost effects were found to have detrimental effects for accelerating fatigue crack initialization in pipes.     

The Impact of Grey Literature in Advancing Global Karst Research: An Information Needs Assessment for a Globally Distributed Interdisciplinary Community

A survey of the global karst community was conducted in 2006. The survey was distributed via the World Wide Web to known karst researchers. The instrument was designed to generate an initial inventory of core grey information types, to assess levels of usage of grey information by the respondents, and to gauge the karst community’s willingness to participate in building and expanding both this collection and the associated controlled vocabularies.
