    Performance over professional learning and the complexity puzzle: lesson observation in England’s further education sector

    Get PDF
    Attempts to measure the quality of teaching and learning have resulted in an overreliance on quantitative performance data and the normalisation of a set of reductionist practices in England’s further education sector in recent years. Focusing on lesson observation as an illustrative example and drawing on data from a national study, this article examines the application of observation and its impact on further education teachers’ practice. In viewing lesson observation through a complexity theory lens and contextualising it against the wider neoliberal backdrop of the marketisation of education, we seek to critique the inadequacies of current reductionist approaches to teacher evaluation, whilst simultaneously opening up a debate regarding the consequences of seeing classrooms as complex adaptive systems. In focusing on performative models of lesson observation in particular, the article exposes what we perceive as some of the epistemological and methodological shortcomings of neoliberalism in practice, but also offers an alternative way forward in dealing with the contested practice of evaluating the quality of teaching and learning

    Quadratic fermionic interactions yield effective Hamiltonians for adiabatic quantum computing

    Full text link
    Polynomially-large ground-state energy gaps are rare in many-body quantum systems, but useful for adiabatic quantum computing. We show analytically that the gap is generically polynomially-large for quadratic fermionic Hamiltonians. We then prove that adiabatic quantum computing can realize the ground states of Hamiltonians with certain random interactions, as well as the ground states of one, two, and three-dimensional fermionic interaction lattices, in polynomial time. Finally, we use the Jordan-Wigner transformation and a related transformation for spin-3/2 particles to show that our results can be restated using spin operators in a surprisingly simple manner. A direct consequence is that the one-dimensional cluster state can be found in polynomial time using adiabatic quantum computing.Comment: 14 page

    Reduction of low- and high-grade cervical abnormalities associated with high uptake of the HPV bivalent vaccine in Scotland

    In Scotland, a national HPV immunisation programme began in 2008 for 12-13 year olds, with a catch-up campaign from 2008-2011 for those under the age of 18. To monitor the impact of HPV immunisation on cervical disease at the population level, a programme of national surveillance was established.  We analysed colposcopy data from a cohort of women born between 1988-1992 who entered the Scottish Cervical Screening Programme (SCSP) and were aged 20-21 in 2008-2012.  By linking datasets from the SCSP and colposcopy services, we observed a significant reduction in diagnoses of cervical intraepithelial neoplasia 1 (CIN 1) (RR 0.71, 95% CI 0.58 to 0.87, p=0.0008), CIN 2 (RR 0.5, 95% CI 0.4, 0.63, p<0.0001) and CIN 3 (RR 0.45, 95% CI 0.35 to 0.58, p< 0.0001) for women who received 3 doses of vaccine compared with unvaccinated women.  To our knowledge, this is one of the first studies to show a reduction of low and high grade cervical intraepithelial neoplasia associated with high uptake of the HPV bivalent vaccine at the population level. These data are very encouraging for countries that have achieved high HPV vaccine uptake

    The Physics of Heavy Flavours at SuperB

    Full text link
    This is a review of the SuperB project, covering the accelerator, detector, and highlights of the broad physics programme. SuperB is a flavour factory capable of performing precision measurements and searches for rare and forbidden decays of Bu,d,sB_{u,d,s}, DD, τ\tau and Υ(nS)\Upsilon({\mathrm{nS}}) particles. These results can be used to test fundamental symmetries and expectations of the Standard Model, and to constrain many different hypothesised types of new physics. In some cases these measurements can be used to place constraints on the existence of light dark matter and light Higgs particles with masses below 10GeV/c210GeV/c^2. The potential impact of the measurements that will be made by SuperB on the field of high energy physics is also discussed in the context of data taken at both high energy in the region around the \Upsilon({\mathrm{4S}})$, and near charm threshold.Comment: 49 pages, topical review submitted to J.

    The state of professional practice and policy in the English further education system: a view from below

    Get PDF
    This paper addresses a recurring theme regarding the UK’s Vocational Education and Training (VET) policy in which Further Education (FE) and training are primarily driven by employer demand. It explores the tensions associated with this process on the everyday working practices of FE practitioners and institutions and its impact on FE’s contribution to the wider processes of social and economic inclusion. At a time when Ofsted and employer-led organisations have cast doubt on the contribution of FE, we explore pedagogies of practice that are often unacknowledged by the current audit demands of officialdom. We argue that such practice provides a more enlightened view of the sector and the challenges it faces in addressing wider issues of social justice, employability and civic regeneration. At the same time, the irony of introducing laissez-faire initiatives designed to remove statutory qualifications for FE teachers ignores the progress made over the past decade in raising the professional profile and status of teachers and trainers in the sector. In addressing such issues, the paper explores the limits and possibilities of constructing professional and vocational knowledge from networks and communities of practice, schools, universities, business, employers and local authorities, in which FE already operates

    Interprofessional communication with hospitalist and consultant physicians in general internal medicine : a qualitative study

    Get PDF
    This study helps to improve our understanding of the collaborative environment in GIM, comparing the communication styles and strategies of hospitalist and consultant physicians, as well as the experiences of providers working with them. The implications of this research are globally important for understanding how to create opportunities for physicians and their colleagues to meaningfully and consistently participate in interprofessional communication which has been shown to improve patient, provider, and organizational outcomes

    From littérature engagée to engaged translation : staging Jean-Paul Sartre’s theatre as a challenge to Franco’s rule in Spain

    Get PDF
    The practice of creating translations that ‘rouse, inspire, witness, mobilize, and incite to rebellion’ is described by Maria Tymoczko, following Jean-Paul Sartre's littérature engagée, as ‘engaged translation’. In Spain, under the Franco dictatorship (1939–1975), the theatre became a site of opposition to his rule and the creation of ‘engaged’ translations of foreign plays was one of the ways in which alternative social and political realities were transmitted to local audiences. This was particularly evident during the so-called apertura period (1962–1969), when Spain's political leaders embraced more liberal and outward-facing cultural policies as part of their efforts to ensure the regime's continuity. Drawing on archival evidence from the state censorship files held at Archivo General de la Administración (AGA) in Alcalá de Henares, this article considers how ‘engaged’ translations of Sartre's theatre were employed as instruments of cultural opposition to the Spanish dictatorship. It also argues that an analysis of the files both helps us to understand the role of censorship in shaping an official version of the past, and shines a light on the memory of a little-studied aspect of cultural activism in the Spanish theatre.PostprintPeer reviewe

    Bile acid–sensitive tuft cells regulate biliary neutrophil influx

    Full text link
    Inflammation and dysfunction of the extrahepatic biliary tree are common causes of human pathology, including gallstones and cholangiocarcinoma. Despite this, we know little about the local regulation of biliary inflammation. Tuft cells, rare sensory epithelial cells, are particularly prevalent in the mucosa of the gallbladder and extrahepatic bile ducts. Here, we show that biliary tuft cells express a core genetic tuft cell program in addition to a tissue-specific gene signature and, in contrast to small intestinal tuft cells, decreased postnatally, coincident with maturation of bile acid production. Manipulation of enterohepatic bile acid recirculation revealed that tuft cell abundance is negatively regulated by bile acids, including in a model of obstructive cholestasis in which inflammatory infiltration of the biliary tree correlated with loss of tuft cells. Unexpectedly, tuft cell–deficient mice spontaneously displayed an increased gallbladder epithelial inflammatory gene signature accompanied by neutrophil infiltration that was modulated by the microbiome. We propose that biliary tuft cells function as bile acid–sensitive negative regulators of inflammation in biliary tissues and serve to limit inflammation under homeostatic conditions
