    User Studies zur digitalen Forschungsinfrastruktur von CLARIAH-DE: Konzept, Umsetzung, Erkenntnisse

    No full text
    Für den Erfolg digitaler Forschungsinfrastrukturen wie CLARIAH-DE gilt es sicherzustellen, dass die Bedarfe der unterschiedlichen Ziel- und Nutzendengruppen erkannt und bestmöglich adressiert werden. Hier bietet sich die Vorbereitung von User Studies, also der Untersuchung der Bedürfnisse, der Motivationen und des Verhaltens der Nutzenden an: Sie tragen wesentlich dazu bei, (Wissenschafts )Communitys in ihrer Komplexität kennenzulernen und auf ihre Bedarfe hin zu analysieren. Die geistes- und kulturwissenschaftliche Community von CLARIAH-DE kennzeichnet sich durch das steigende Interesse an digitalen Methoden und Angeboten und gleichzeitig durch große Unterschiede bezüglich der Vertrautheit mit diesen. Wir haben diese Herausforderung zum Anlass genommen, die vielfältigen Bedarfe und Nutzungsszenarien der verschiedenen Gruppen näher zu beleuchten. Hierfür wurden drei Methoden erprobt: qualitative Interviews mit verschiedenen Zielgruppen, ein Workshop für Einsteiger innen in das digitale Forschungsdatenmanagement und eine Usability- und User Experience-Studie zur CLARIAH-DE-Website. Das zugrundeliegende Konzept der User Studies, ihre Umsetzung und die daraus gewonnenen Erkenntnisse werden in dem vorliegenden Paper beschrieben und kritisch reflektiert. Es schließt mit einem Ausblick und Best-Practice-Empfehlungen für die Einbeziehung der Community hinsichtlich breiterer Kontexte zum Aufbau und Betrieb von Forschungsdateninfrastruktur wie in der NFDI

    Fibrous Cap Thickness and Smooth Muscle Cell Apoptosis in High-grade Carotid Artery Stenosis

    AbstractObjectiveThere is growing evidence that, in high-grade internal carotid artery (ICA) stenosis, continuous fibrous cap thinning is not mandatory for plaque rupture and symptom development. The possibility that smooth muscle cell (SMC) apoptosis is involved in loss of fibrous cap volume has only been examined in a limited number of patients with high grade carotid artery stenosis.MethodsEndarterectomy specimens from n=38 consecutive patients undergoing surgery for high-grade ICA stenosis (≥70%) were transversely sectioned at 2mm intervals. Plaque instability was defined clinically, by a history of recent ischemic symptoms (<60 days before surgery; n=19) attributable to the stenosis, or histopathologically by the presence of plaque rupture (n=14). Detailed morphometric analyses of the fibrous cap was based on routine stains; for DNA in situ end labeling the TUNEL technique was used. SMCs were identified by immunostaining for SMC actin.ResultsWe found no significant difference between symptomatic/asymptomatic or ruptured/unruptured plaque with respect to various morphometric measures of the fibrous cap (i.e. mean area, number of plaque sections with fibrous cap, necrotic core-to-lumen distance at its thinnest or thickest part). The mean (±SD) apoptotic SMCs per thousand within the fibrous cap was significantly higher in symptomatic vs. asymptomatic (64.53±77.3 vs. 6.71±11.9; P<0.001) but not in ruptured plaques (43.3±64.4 vs. 30.1±60.9; P=0.117).ConclusionsThese data suggest that continuous thinning of the fibrous cap is not an essential prerequisite for plaque rupture in ICA stenosis. Symptomatic, but not ruptured plaque, were associated with the highest number of apoptotic SMC. Thus, it seems unlikely that SMC apoptosis promotes plaque rupture by fibrous cap thinning

    The Altitudinal Niche-Breadth Hypothesis in Insect-Plant Interactions

    Studies aiming at explaining specialization along latitudinal gradients of plant-herbivore interactions have, to date, yielded inconclusive results. Here we propose the use of steep altitudinal gradients for dissecting factors driving evolution of polyphagy in insect herbivores. First, we test whether colonization of high elevation environment favours increased niche-breadth in two disparate insect groups - the wood-boring beetles and the pollinator group of bees - and show increased polyphagy at higher altitudes in both groups. We then assess classic assumptions transferred from the 'latitude-niche-breadth hypothesis', particularly the increase in environmental variability at high, compared to low, altitude. Finally, we discuss alternative mechanisms shaping the observed pattern of increased polyphagy in altitude, including variation in plant quality and predator pressure at different altitudes. We thus suggest evidence for the 'altitude niche-breadth hypothesis', in which both abiotic and biotic conditions, including increased variability and an increase of the potential feeding niche-breadth, promote evolution for increased insect polyphagy in altitude
