Improving technology transfer through national systems of innovation: climate relevant innovation-system builders (CRIBs)
The Technology Executive Committee (TEC) of the United Nations Framework Convention on Climate Change (UNFCCC) recently convened a workshop seeking to understand how strengthening national systems of innovation (NSIs) might help to foster the transfer of climate technologies to developing countries. This article reviews insights from the literatures on Innovation Studies and Socio-Technical Transitions to demonstrate why this focus on fostering innovation systems has potential to be more transformative as an international policy mechanism for climate technology transfer than anything the UNFCCC has considered to date. Based on insights from empirical research, the article also articulates how the existing architecture of the UNFCCC Technology Mechanism could be usefully extended by supporting the establishment of CRIBs (climate relevant innovation-system builders) in developing countries – key institutions focused on nurturing the climate-relevant innovation systems and building technological capabilities that form the bedrock of transformative, climate-compatible technological change and development

The Open Navigation Surface Project
Many hydrographic and oceanographic agencies have moved or are moving towards gridded bathymetric products. However, there is no accepted format to allow these grids to be exchanged while maintaining data and metadata integrity. This paper describes the Open Navigation Surface (ONS) Project, which aims to fill this gap. The ONS Project is an open-source software project designed to provide a freely available, portable source-code library to encapsulate gridded bathymetric surfaces with associated uncertainty values. The data file format is called a Bathymetric Attributed Grid (BAG). The BAG is developed and maintained by the ONS Working Group (ONSWG), and the source code is available via the ONS websit
Genomic analysis of clostridioides difficile recovered from horses in Western Australia
Clostridioides difficile poses an ongoing threat as a cause of gastrointestinal disease in humans and animals. Traditionally considered a human healthcare-related disease, increases in community-associated C. difficile infection (CDI) and growing evidence of inter-species transmission suggest a wider perspective is required for CDI control. In horses, C. difficile is a major cause of diarrhoea and life-threatening colitis. This study aimed to better understand the epidemiology of CDI in Australian horses and provide insights into the relationships between horse, human and environmental strains. A total of 752 faecal samples from 387 Western Australian horses were collected. C. difficile was isolated from 104 (30.9%) horses without gastrointestinal signs and 19 (37.8%) with gastrointestinal signs. Of these, 68 (55.3%) harboured one or more toxigenic strains, including C. difficile PCR ribotypes (RTs) 012 (n = 14), 014/020 (n = 10) and 087 (n = 7), all prominent in human infection. Whole-genome analysis of 45 strains identified a phylogenetic cluster of 10 closely related C. difficile RT 012 strains of equine, human and environmental origin (0–62 SNP differences; average 23), indicating recent shared ancestry. Evidence of possible clonal inter-species transmission or common-source exposure was identified for a subgroup of three horse and one human isolates, highlighting the need for a One Health approach to C. difficile surveillance
The interconnection between galaxy mergers, AGN activity and rapid quenching of star formation in simulated post-merger galaxies
We investigate the role of galaxy mergers on supermassive black hole (SMBH)
accretion and star formation quenching in three state-of-the-art cosmological
simulations with contrasting physics models: EAGLE, Illustris and IllustrisTNG.
We find that recently coalesced 'post-mergers' in all three simulations have
elevated SMBH accretion rates by factors of ~2-5. However, rapid (within 500
Myr of coalescence) quenching of star formation is rare, with incidence rates
of 0.4% in Illustris, 4.5% in EAGLE and 10% in IllustrisTNG. The rarity of
quenching in post-mergers results from substantial gas reservoirs that remain
intact after the merger. The post-mergers that do successfully quench tend to
be those that had both low pre-merger gas fractions as well as those that
experience the largest gas losses. Although rare, the recently quenched
fraction of post-mergers is still elevated compared to a control sample of
non-mergers by factors of two in IllustrisTNG and 11 in EAGLE. Conversely,
quenching is rarer in Illustris post-mergers than in their control. Recent
observational results by Ellison et al. have found rapid quenching to be at
least 30 times more common in post-mergers, a significantly higher excess than
found in any of the simulations. Our results, therefore, indicate that whilst
merger-induced SMBH accretion is a widespread prediction of the simulations,
its link to quenching depends sensitively on the physics models, and that none
of the subgrid models of the simulations studied here can fully capture the
connection between mergers and rapid quenching seen in observations.Comment: This article has been accepted for publication in Monthly Notices of

The Sustained Effects of CBT Training on Therapist Competence and Patient Outcomes
The continued effectiveness of in-service psychological therapy training requires evaluation. This study assessed therapist competence and patient clinical outcome during cognitive behaviour therapy training and 12+ months post-training. Trainee competence was assessed using audio-recorded sessions rated on the Cognitive Therapy Scale Revised at the beginning (n = 33) and end of training (n = 45), and at least 12 months post-training (n = 45). Pre-to-posttreatment clinical outcome for trainees’ patients during the course (n = 360) and post-training (n = 360) was evaluated using standardised self-report measures. The relationship between therapist competence and patient outcomes was explored. Trainees achieved competence during training (100%, n = 45) and largely maintained competence post-training (84%, n = 38). Patients demonstrated pre-to-posttreatment effect sizes between 1.38 and 1.89 and reliable improvement exceeding 80% during and after training. Competence was not significantly associated with patient outcome. Trainees predominantly maintained competence and achieved good clinical outcomes post-training. Structured training and continued use of regular supervision possibly supported retention of competence
