    Change management and relocation: a moving experience

    Organisational change brings with it a need for facilities changes. Merging, splitting, downsizing, upsizing, adaptations, are all physical manifestations of the need for change. Along with these changes are innumerable human and organizational changes that are often unintended and poorly understood. The purpose of this paper is to explore what the wider literature has to say about these secondary effects. Specifically, we consider the displacement and fracturing of established modes of operation embedded in previously occupied buildings and the formation of new modes of operation. The paper considers the application of ‘griefwork’ initially proposed by Kubler-Ross in the 1950s. Such an approach provides a means to understand physical change. Furthermore, in the following analysis we consider research currently being undertaken at MediacityUK to trace the transition experiences of those impacted by a major facility change across a split-site. The research findings will provide insights concerning architectural and facilities management interventions that can significantly reduce the human and organizational cost of change, which though difficult to measure, have a profound effect on the sustainability of an organization

    The D(D3)D(D_{3})-anyon chain: integrable boundary conditions and excitation spectra

    Get PDF
    Chains of interacting non-Abelian anyons with local interactions invariant under the action of the Drinfeld double of the dihedral group D3D_3 are constructed. Formulated as a spin chain the Hamiltonians are generated from commuting transfer matrices of an integrable vertex model for periodic and braided as well as open boundaries. A different anyonic model with the same local Hamiltonian is obtained within the fusion path formulation. This model is shown to be related to an integrable fusion interaction round the face model. Bulk and surface properties of the anyon chain are computed from the Bethe equations for the spin chain. The low energy effective theories and operator content of the models (in both the spin chain and fusion path formulation) are identified from analytical and numerical studies of the finite size spectra. For all boundary conditions considered the continuum theory is found to be a product of two conformal field theories. Depending on the coupling constants the factors can be a Z4Z_4 parafermion or a M(5,6)\mathcal{M}_{(5,6)} minimal model.Comment: Major revisions have been mad

    Integrable anyon chains: from fusion rules to face models to effective field theories

    Get PDF
    Starting from the fusion rules for the algebra SO(5)2SO(5)_2 we construct one-dimensional lattice models of interacting anyons with commuting transfer matrices of `interactions round the face' (IRF) type. The conserved topological charges of the anyon chain are recovered from the transfer matrices in the limit of large spectral parameter. The properties of the models in the thermodynamic limit and the low energy excitations are studied using Bethe ansatz methods. Two of the anyon models are critical at zero temperature. From the analysis of the finite size spectrum we find that they are effectively described by rational conformal field theories invariant under extensions of the Virasoro algebra, namely WB2\mathcal{W}B_2 and WD5\mathcal{W}D_5, respectively. The latter contains primaries with half and quarter spin. The modular partition function and fusion rules are derived and found to be consistent with the results for the lattice model.Comment: 43 pages, published versio

    Taking A Stand: The Effects Of Standing Desks On Task Performance And Engagement

    Time spent sitting is associated with negative health outcomes, motivating some individuals to adopt standing desk workstations. This study represents the first investigation of the effects of standing desk use on reading comprehension and creativity. In a counterbalanced, within-subjects design, 96 participants completed reading comprehension and creativity tasks while both sitting and standing. Participants self-reported their mood during the tasks and also responded to measures of expended effort and task difficulty. In addition, participants indicated whether they expected that they would perform better on work-relevant tasks while sitting or standing. Despite participants’ beliefs that they would perform worse on most tasks while standing, body position did not affect reading comprehension or creativity performance, nor did it affect perceptions of effort or difficulty. Mood was also unaffected by position, with a few exceptions: Participants exhibited greater task engagement (i.e., interest, enthusiasm, and alertness) and less comfort while standing rather than sitting. In sum, performance and psychological experience as related to task completion were nearly entirely uninfluenced by acute (~30-min) standing desk use. View Full-Tex

    To germinate or not to germinate : a question of dormancy relief not germination stimulation

    Get PDF
    A common understanding of the control of germination through dormancy is essential for effective communication between seed scientists whether they are ecologists, physiologists or molecular biologists. Vleeshouwers et al. (1995) realized that barriers between disciplines limited progress and through insightful conclusions in their paper ‘Redefining seed dormancy: an attempt to integrate physiology and ecology’, they did much to overcome these barriers at that time. However, times move on, understanding develops, and now there is a case for ‘Redefining seed dormancy as an integration of physiology, ecology and molecular biology’. Finch-Savage and Leubner-Metzger (2006) had this in mind when they extended and re-interpreted the definition of dormancy proposed by Vleeshouwers et al. (1995), by considering dormancy as a having a number of layers that must be removed, with the final layer of dormancy being synonymous with the stimulation/induction of germination
