Dependence on plasma shape and plasma fueling for small edge-localized mode regimes in TCV and ASDEX Upgrade
Within the EUROfusion MST1 work package, a series of experiments has been conducted on AUG and TCV devices to disentangle the role of plasma fueling and plasma shape for the onset of small ELM regimes. On both devices, small ELM regimes with high confinement are achieved if and only if two conditions are fulfilled at the same time. Firstly, the plasma density at the separatrix must be large enough (n e,sep/n G ∼ 0.3), leading to a pressure profile flattening at the separatrix, which stabilizes type-I ELMs. Secondly, the magnetic configuration has to be close to a double null (DN), leading to a reduction of the magnetic shear in the extreme vicinity of the separatrix. As a consequence, its stabilizing effect on ballooning modes is weakened
Sex matters: retrospective data collection on the date of commencement of ART for HIV-positive women and men in the German KompNet cohort (1991-2009)
HIV Activates the Tyrosine Kinase Hck to Secrete ADAM Protease-Containing Extracellular Vesicles
HIV-Nef activates the myeloid cell-typical tyrosine kinase Hck, but its molecular role in the viral life cycle is not entirely understood. We found that HIV plasma extracellular vesicles (HIV pEV) containing/10 proteases and Nef also harbor Hck, and analyzed its role in the context of HIV pEV secretion. Myeloid cells required Hck for the vesicle-associated release of ADAM17. This could be induced by the introduction of Nef and implied that HIV targeted Hck for vesicle-associated ADAM17 secretion from a myeloid compartment. The other contents of HIV-pEV, however, including miRNA and effector protein profiles, as well as the presence of haptoglobin suggested hepatocytes as a possible cellular source. HIV liver tissue analysis supported this assumption, revealing induction of Hck translation, evidence for ADAMprotease activation and HIV infection. Our findings suggest that HIV targets Hck to induce pro-inflammatory vesicles release and identifies hepatocytes as a possible host cell compartment. (c) 2018 The Authors. Published by Elsevier B.V.

Specifying computer-supported collaboration scripts
Collaboration scripts are activity programs which aim to foster collaborative learning by structuring interaction between learners. Computer-supported collaboration scripts generally suffer from the problem of being restrained to a specific learning platform and learning context. A standardization of collaboration scripts first requires a specification of collaboration scripts that integrates multiple perspectives from computer science, education and psychology. So far, only few and limited attempts at such specifications have been made. This paper aims to consolidate and expand these approaches in light of recent findings and to propose a generic framework for the specification of collaboration scripts. The framework enables a description of collaboration scripts using a small number of components (participants, activities, roles, resources and groups) and mechanisms (task distribution, group formation and sequencing)

Redefining SME Productivity Measurement and Assessment for a Low Carbon Economy
YesThe UK faces the joint economic policy challenges of raising productivity and tackling climate
change. This report challenges prevailing narrow market-based views of productivity, by
examining the £4bn UK early stage Cleantech innovation finance market. We find that Cleantech
innovation is frequently capital intensive and long horizon (5-10+ years), measured by shorterterm technology readiness level (TRL) and intellectual property (IP) progression. Longer-term
sustainable productivity impacts remain little understood and, where applied, narrowly relate to
customer adoption. This leads to Cleantech environmental impact investor logics that primarily
relate to end user financial value (customer sales). There is little consideration for non-market
values from, for example, circular economy (CE) and wider environmental spillover impacts (e.g.
supply chains). Whilst few Cleantechs currently successfully commercialise, a small proportion
exhibit high employment and sales growth and global environmental impact. Improved
understanding of the broader environmental impacts of Cleantechs, through the adoption of
environmental impact metrics (EIMs) can (i) add to a more holistic notion of productivity and (ii)
improve the efficiency of the finance escalator, enabling more Cleantechs to contribute
significantly to establishing the UK as a globally leading low carbon economy.ESR
A Foucauldian look at the design jury
There can be little argument that the design jury features as a key symbolic event in the education of the architect. However, whilst the centrality of the design jury is widely acknowledged there continues to be considerable disagreement about exactly what students learn and how. This paper, inspired by Michel Foucault's genealogical studies of relationship between knowledge, power and the formation of the modern subject, reports on the findings of a year-long ethnographic study carried out in a British school of architecture that sought to explicate the workings of the design jury as specific form of pedagogic practice. The study uncovered a considerable misalignment between the espoused aims of the design jury and the effects of the jury in practice. Given the widespread use of the design jury these findings suggest that it is time for schools to review, modify or even abandon the design jury
Efficacy, safety, tolerability and pharmacokinetics of a novel human immune globulin subcutaneous, 20%: a Phase 2/3 study in Europe in patients with primary immunodeficiencies
A highly concentrated (20%) immunoglobulin (Ig)G preparation for subcutaneous administration (IGSC 20%), would offer a new option for antibody replacement therapy in patients with primary immunodeficiency diseases (PIDD). The efficacy, safety, tolerability and pharmacokinetics of IGSC 20% were evaluated in a prospective trial in Europe in 49 patients with PIDD aged 2-67 years. Over a median of 358 days, patients received 2349 IGSC 20% infusions at monthly doses equivalent to those administered for previous intravenous or subcutaneous IgG treatment. The rate of validated acute bacterial infections (VASBIs) was significantly lower than 1 per year (0.022/patient-year, P /= 8 g/l. There was no serious adverse event (AE) deemed related to IGSC 20% treatment; related non-serious AEs occurred at a rate of 0.101 event/infusion. The incidence of local related AEs was 0.069 event/infusion (0.036 event/infusion, when excluding a 13-year-old patient who reported 79 of 162 total related local AEs). The incidence of related systemic AEs was 0.032 event/infusion. Most related AEs were mild, none were severe. For 64.6% of patients and in 94.8% of IGSC 20% infusions, no local related AE occurred. The median infusion duration was 0.95 (range = 0.3-4.1) h using mainly one to two administration sites [median = 2 sites (range = 1-5)]. Almost all infusions (99.8%) were administered without interruption/stopping or rate reduction. These results demonstrate that IGSC 20% provides an effective and well-tolerated therapy for patients previously on intravenous or subcutaneous treatment, without the need for dose adjustment
Embodied Discourses of Literacy in the Lives of Two Preservice Teachers
This study examines the emerging teacher literacy identities of Ian and A.J., two preservice teachers in a graduate teacher education program in the United States. Using a poststructural feminisms theoretical framework, the study illustrates the embodiment of literacy pedagogy discourses in relation to the literacy courses’ discourse of comprehensive literacy and the literacy biographical discourses of Ian and A.J. The results of this study indicate the need to deconstruct how the discourse of comprehensive literacy limits how we, as literacy teacher educators, position, hear and respond to our preservice teachers and suggests the need for differentiation in our teacher education literacy courses
