    The impact of National Qualifications Frameworks: by which yardstick do we measure dreams?

    National Qualifications Frameworks (NQFs) are a global phenomenon. This is evidenced by their scale, coverage and intrinsic link with education policy across Europe and beyond. Research into their impact has encompassed a number of perspectives; theoretical, practical and evaluative. Yet, despite the existence of critical literature related to the development, design and impact of NQFs, little research has questioned the actual feasibility of researching the ‘impact’ of NQFs per se. The arguments in this paper position such research as both unfeasible and futile: a dream for which it is impossible to identify a suitable yardstick to measure. We base our argument around three broad themes: linguistics and semantics; homogeneity; and methodological complexity. Around these themes, we aim to show why such research has proved problematic and, in doing so, contribute to the field as it explores the impact of NQFs in the future

    Aligning the times: Exploring the convergence of researchers, policy makers and research evidence in higher education policy making

    The complexity of contemporary higher education policy making and the multitude of evidences and actors in policy networks mean that relationships between higher education researchers, policy makers and research evidence are not straightforward. In this article, we use a theoretical lens of time, Adams’ Timescapes, to explore this relationship and better understand why the research and policy worlds are frequently described as divided. Drawing on in-depth interviews with higher education researchers, policy makers and research funders, we show how research and policy have different interpretations of time. We discuss the Timeframes, or lengths, of work and career, the Temporality, or complexity, of ‘evidence’, of networks and relationships, and the importance of elements such as Timing, or synchronisation, and Tempo, or pace. We conclude that policy makers and higher education researchers may be better able to make sense of the problematic nature of aligning their concerns, interests and actions through understanding different Timescapes

    BSE infectivity survives burial for five years with only limited spread

    © 2019, The Author(s). The carcasses of animals infected with bovine spongiform encephalopathy (BSE), scrapie or chronic wasting disease (CWD) that remain in the environment (exposed or buried) may continue to act as reservoirs of infectivity. We conducted two experiments under near-field conditions to investigate the survival and dissemination of BSE infectivity after burial in a clay or sandy soil. BSE infectivity was either contained within a bovine skull or buried as an uncontained bolus of BSE-infected brain. Throughout the five-year period of the experiment, BSE infectivity was recovered in similar amounts from heads exhumed annually from both types of soil. Very low levels of infectivity were detected in the soil immediately surrounding the heads, but not in samples remote from them. Similarly, there was no evidence of significant lateral movement of infectivity from the buried bolus over 4 years although there was a little vertical movement in both directions. However, bioassay analysis of limited numbers of samples of rain water that had drained through the bolus clay lysimeter indicated that infectivity was present in filtrates. sPMCA analysis also detected low levels of PrP Sc in the filtrates up to 25 months following burial, raising the concern that leakage of infectivity into ground water could occur. We conclude that transmissible spongiform encephalopathy infectivity is likely to survive burial for long periods of time, but not to migrate far from the site of burial unless a vector or rain water drainage transports it. Risk assessments of contaminated sites should take these findings into account

    Phytochromes control metabolic flux, and their action at the seedling stage determines adult plant biomass

    Phytochrome (phy) photoreceptors are known to regulate plastic growth responses to vegetation shade. However, recent reports also suggest an important role for phys in carbon resource management, metabolism, and growth. Here, we use 13CO2 labelling patterns in multi-allele phy mutants to investigate the role of phy in the control of metabolic fluxes. We also combine quantitative data of 13C incorporation into protein and cell wall polymers, gas exchange measurements and system modelling to investigate why biomass is decreased in adult multi-allele phy mutants. Phy influences the synthesis of stress metabolites like raffinose and proline, and the accumulation of sugars, possibly through regulating vacuolar sugar transport. Remarkably, despite their modified metabolism and vastly altered architecture, growth rates in adult phy mutants resemble those of wild-type plants. Our results point to delayed seedling growth and smaller cotyledon size as the cause of the adult-stage phy mutant biomass defect. Our data signify a role for phy in metabolic stress physiology, carbon partitioning and illustrate that phy action at the seedling stage sets the trajectory for adult biomass production
