An exploratory interview study of university teacher resilience
Although teacher resilience research has blossomed in the last 5â10 years, the resilience of schoolteachers and principals has been the main focus of research. There is little research exploring the resilience of university teachers. This chapter presents findings from an exploratory study regarding university teacher resilience. Participants were 26 university teachers, 17 from Germany and 9 from Australia. Semi-structured interviews were conducted to explore the challenges, coping strategies and work-related emotions of participants and how they view resilience in the context of their work. Findings revealed challenges such as heavy workload, interpersonal relationships, time management and finding the right balance between teaching and research activities. Strategies include social support, time management and consciously maintaining a healthy work-life balance. The findings are discussed in light of a model of university teacher resilience, which is adapted to take into account specific aspects of university work
In vivo systemic toxicity assessment of an oxidized dextrin-based hydrogel and its effectiveness as a carrier and stabilizer of granular synthetic bone substitutes
The worldwide incidence of bone disorders is raising, mainly due to ageing population. The lack of effective treatments is pushing the development of synthetic bone substitutes (SBSs). Most ceramic-based SBSs commercially available display limited handling properties. Attempting to solve these issues and achieve wider acceptance by the clinicians, granular ceramics have been associated with hydrogels to produce injectable/moldable SBSs. Dextrin, a low-molecular-weight carbohydrate, was used to develop a fully resorbable and injectable hydrogel. It was firstly oxidized with sodium periodate and then cross-linked with adipic acid dihydrazide. The in vivo biocompatibility and safety of the dextrin-based hydrogel (HG) was assessed by subacute systemic toxicity and skin sensitization tests, using rodent models. The results showed that the HG did not induce any systemic toxic effect, skin reaction or genotoxicity, neither impaired the bone repair/regeneration process. Then, the HG was successfully combined with granular bone substitute, registered as BonelikeÂź (250-500 ?m) to obtain a mouldable/injectable SBS, which was implanted in tibial fractures in goats for 3 and 6 weeks. The obtained results showed that HG allowed the stabilization of the granules into the defect, ensuring effective handling and moulding properties of the formulation, as well as an efficient cohesion of the granules.

Search for new resonances decaying to a or boson and a Higgs boson in the , , and channels with collisions at TeV with the ATLAS detector
See paper for full list of authors, 18 pages (plus author list + cover pages: 36 pages total), 13 figures, 1 table. Submitted to PLB. All figures including auxiliary figures are available at https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/EXOT-2015-18/International audienceA search is presented for new resonances decaying to a or boson and a Higgs boson in the , , and channels in collisions at TeV with the ATLAS detector at the Large Hadron Collider using a total integrated luminosity of 3.2 fb. The search is conducted by looking for a localized excess in the / invariant or transverse mass distribution. No significant excess is observed, and the results are interpreted in terms of constraints on a simplified model based on a phenomenological Lagrangian of heavy vector triplets
