Extending, broadening and rethinking existing research on transfer of training
Research on transfer of training has a long history, with thousands of empirical studies since the 1950s investigating whether, and under which conditions, knowledge and skills acquired during training are subsequently used in the work environment (see reviews by Baldwin and Ford, 1988, Blume et al., 2010 and Burke and Hutchins, 2007). The generation of such an abundance of research can be linked to organisationsâ fundamental and ongoing concern to ensure that their employees possess the necessary knowledge and skills from their employer to maintain a competitive advantage and thrive economically. Training and development is, however, extremely costly to organisations, which has created the need to determine the effectiveness of training, and the conditions under which transfer of training is optimal. A recent overview of âwhat really mattersâ for successful transfer of training (Grossman & Salas, 2011), aimed at a training and development readership, summarized the most influential variables emerging from this vast body of research. Based on the expectation that the list of factors which may contribute to influence transfer could always be extended and that it would be impractical to incorporate every single factor in research designs, the authors recommended a shift in future research towards deeper investigations of the conditions under which selected variables are more or less influential in their relationship with training.
This Special Issue contributes to this important research agenda and extends it further through the inclusion of a diverse collection of conceptual contributions and reviews, from several scientific disciplines, a plurality of theoretical perspectives and a range of methodological approaches. Expanding the theoretical grounding underpinning empirical work on transfer of training and scrutinizing existing conceptualizations of the notion of transfer is timely in light of widespread concerns from organisations about minimal return on investment in training, and repeated evidence in the transfer of training literature of an enduring âtransfer problemâ.
The aim of this article is to explore the value of extending, broadening and rethinking existing research on transfer of training. The benefits of extending research on transfer of training is considered first, through examining how the contributions of this Special Issue add to the existing literature on transfer of training, and the implications of the new insights for addressing the âtransfer problemâ. How transfer of training research could be broadened, thus enriched, through incorporating ideas from recent literature on transfer of learning is considered next. Finally, proposals to rethink transfer as boundary crossing from an activity theory perspective are scrutinized for their potential to better understand the learning that takes place at the boundaries of training and work environments. The article concludes by elaborating on the conceptual value of a refocus on âtransfer of learning from trainingâ within a perspective of adaptive learning, and a call for cross-fertilisation with the extensive theory grounded literatures on transfer of learning and boundary crossing

Losing by Expanding: Corralling the Runaway Object
At the time of publication C. Spinuzzi was at the University of Texas at Austin.Third-generation activity theory (3GAT) has become a popular theoretical and methodological framework for writing studies, particularly in technical communication. 3GAT involves identifying an object, a material or problem that is cyclically transformed by collective activity. The object is the linchpin of analysis in the empirical case. Yet the notion of object has expanded methodologically and theoretically over time, making it difficult to reliably bound an empirical case. In response, this article outlines the expansion of the object, diagnoses this expansion, and proposes an alternate approach that constrains the object for case-study research in writing studies.Writin

Information systems: a cyborg discipline?
This paper argues for a model of information systems in terms of cyborgs â a boundary-crossing mixture of the technical and the social. The argument for this model is substantiated from the personal experience of the author, presented as examples of being a cyborg researcher within a disciplinary context. Lessons for information systems are drawn
Who do they think they are? The changing identities of professional administrators and managers in UK higher education
Contemporary universities, serving mass higher education markets, find themselves delivering complex, broadly based projects such as student support and welfare, human resource development, and business enterprise. Established concepts of academic administration and devolved management have been overlaid by more fluid institutional structures and cultures, with a softening of internal and external boundaries (Whitchurch 2004; 2005). These developments have caused major shifts in the identities of professional administrators and managers, as they adopt more projectoriented roles crossing functional and organisational boundaries. This paper considers the dynamics of these changes, in terms that move beyond conventional assumptions about âadministrationâ and âmanagementâ. While identities have been defined traditionally via structured domains such as professional knowledges, institutional boundaries, and the policy requirements of the higher education sector, an emergent âprojectâ domain has fostered the development of an increasingly multi-professional grouping of staff, with implications for career futures
Integrable approach to simple exclusion processes with boundaries. Review and progress
We study the matrix ansatz in the quantum group framework, applying
integrable systems techniques to statistical physics models. We start by
reviewing the two approaches, and then show how one can use the former to get
new insight on the latter. We illustrate our method by solving a model of
reaction-diffusion. An eigenvector for the transfer matrix for the XXZ spin
chain with non-diagonal boundary is also obtained using a matrix ansatz.Comment: 44 page
Traffic jams induced by rare switching events in two-lane transport
We investigate a model for driven exclusion processes where internal states are assigned to the particles. The latter account for diverse situations, ranging from spin states in spintronics to parallel lanes in intracellular or vehicular traffic. Introducing a coupling between the internal states by allowing particles to switch from one to another induces an intriguing polarization phenomenon. In a mesoscopic scaling, a rich stationary regime for the density profiles is discovered, with localized domain walls in the density profile of one of the internal states being feasible. We derive the shape of the density profiles as well as resulting phase diagrams analytically by a mean-field approximation and a continuum limit. Continuous as well as discontinuous lines of phase transition emerge, their intersections induce multi-critical behaviour
Synchronous Context-Free Grammars and Optimal Linear Parsing Strategies
Synchronous Context-Free Grammars (SCFGs), also known as syntax-directed
translation schemata, are unlike context-free grammars in that they do not have
a binary normal form. In general, parsing with SCFGs takes space and time
polynomial in the length of the input strings, but with the degree of the
polynomial depending on the permutations of the SCFG rules. We consider linear
parsing strategies, which add one nonterminal at a time. We show that for a
given input permutation, the problems of finding the linear parsing strategy
with the minimum space and time complexity are both NP-hard
Multi-cover skeins, quivers, and 3d
The relation between open topological strings and representation theory of symmetric quivers is explored beyond the original setting of the knot-quiver correspondence. Multiple cover generalizations of the skein relation for boundaries of holomorphic disks on a Lagrangian brane are observed to generate dual quiver descriptions of the geometry. Embedding into M-theory, a large class of dualities of 3
Multimedia search without visual analysis: the value of linguistic and contextual information
This paper addresses the focus of this special issue by analyzing the potential contribution of linguistic content and other non-image aspects to the processing of audiovisual data. It summarizes the various ways in which linguistic content analysis contributes to enhancing the semantic annotation of multimedia content, and, as a consequence, to improving the effectiveness of conceptual media access tools. A number of techniques are presented, including the time-alignment of textual resources, audio and speech processing, content reduction and reasoning tools, and the exploitation of surface features
