Performance feedback and supervision are essential to the adoption of evidence-based interventions with high treatment integrity in child and youth care organizations. Little is known about the use of treatment integrity measurements in these organizations. For this study, 12 interventions for children and young people in the Netherlands with externalizing behavioral problems were selected. For each intervention, an expert, two supervisors, and two therapists were approached for an interview. In total, 54 semi-structured interviews were conducted. The results show that almost all interventions used treatment integrity instruments (N = 11, 91.7%). Only two used measurements for both QA procedures (certification and recertification) and supervision purposes. Therapists regard treatment integrity measurements as valuable when they are used for multiple purposes and feedback is provided. The results of this study suggest the feasibility of the use of measurements for multiple purposes. Collaborative action is required to develop instruments that effectively contribute to continuous improvement.
This study meta-analytically examined the effect of treatment integrity on client outcomes of evidence-based interventions for juveniles with antisocial behavior. A total of 17 studies, from which 91 effect sizes could be retrieved, were included in the present 3-level meta-analysis. All included studies, to a certain level, adequately implemented procedures to establish, assess, evaluate and report the level of treatment integrity. A moderator analysis revealed that a medium-to-large effect of evidence-based interventions was found when the level of treatment integrity was high (d = 0.633, p < 0.001), whereas no significant effect was found when integrity was low (d = 0.143, ns). Treatment integrity was significantly associated with effect size even when adjusted for other significant moderators, indicating the specific contribution of high levels of treatment integrity to positive client outcomes. This implies that delivering interventions with high treatment integrity to youth with antisocial behavior is vital.
‘Dieren in de dijk’ aims to address the issue of animal burrows in earthen levees, which compromise the integrity of flood protection systems in low-lying areas. Earthen levees attract animals that dig tunnels and cause damages, yet there is limited scientific knowledge on the extent of the problem and effective approaches to mitigate the risk. Recent experimental research has demonstrated the severe impact of animal burrows on levee safety, raising concerns among levee management authorities. The consortium's ambition is to provide levee managers with validated action perspectives for managing animal burrows, transitioning from a reactive to a proactive risk-based management approach. The objectives of the project include improving failure probability estimation in levee sections with animal burrows and enhancing risk mitigation capacity. This involves understanding animal behavior and failure processes, reviewing existing and testing new deterrence, detection, and monitoring approaches, and offering action perspectives for levee managers. Results will be integrated into an open-access wiki-platform for guidance of professionals and in education of the next generation. The project's methodology involves focus groups to review the state-of-the-art and set the scene for subsequent steps, fact-finding fieldwork to develop and evaluate risk reduction measures, modeling failure processes, and processing diverse quantitative and qualitative data. Progress workshops and collaboration with stakeholders will ensure relevant and supported solutions. By addressing the knowledge gaps and providing practical guidance, the project aims to enable levee managers to effectively manage animal burrows in levees, both during routine maintenance and high-water emergencies. With the increasing frequency of high river discharges and storm surges due to climate change, early detection and repair of animal burrows become even more crucial. The project's outcomes will contribute to a long-term vision of proactive risk-based management for levees, safeguarding the Netherlands and Belgium against flood risks.
Mycelium biocomposites (MBCs) are a fairly new group of materials. MBCs are non-toxic and carbon-neutral cutting-edge circular materials obtained from agricultural residues and fungal mycelium, the vegetative part of fungi. Growing within days without complex processes, they offer versatile and effective solutions for diverse applications thanks to their customizable textures and characteristics achieved through controlled environmental conditions. This project involves a collaboration between MNEXT and First Circular Insulation (FC-I) to tackle challenges in MBC manufacturing, particularly the extended time and energy-intensive nature of the fungal incubation and drying phases. FC-I proposes an innovative deactivation method involving electrical discharges to expedite these processes, currently awaiting patent approval. However, a critical gap in scientific validation prompts the partnership with MNEXT, leveraging their expertise in mycelium research and MBCs. The research project centers on evaluating the efficacy of the innovative mycelium growth deactivation strategy proposed by FC-I. This one-year endeavor permits a thorough investigation, implementation, and validation of potential solutions, specifically targeting issues related to fungal regrowth and the preservation of sustained material properties. The collaboration synergizes academic and industrial expertise, with the dual purpose of achieving immediate project objectives and establishing a foundation for future advancements in mycelium materials.
In recent years, frequent earthquakes have been reported in the Groningen region due to gas extraction. The building stock of the region mainly consists of brick masonry structures which were built without any seismic design taken into consideration. Therefore, these structures are extremely vulnerable to the loads coming from the earthquakes hitting the Groningen area on a regular basis. Numerous damage claims for damages on structures arise after every earthquake. In order to protect and reassure the structural integrity of the numerous brick masonry structures (more than 14.000 lay in the seismic zone), innovative solutions need to be developed. One of the approaches is to strengthen these houses extensively, up to a level that earthquake forces do not affect the original structure. This approach results in heavy and most of the times ugly strengthening solutions. A promising technology seems to be the installation of a vibration isolating concrete at the foundation level in order to decrease the vibration demands to the structures during the earthquake events. This latter method has been developed by the partner of this project, Nederboom, and will be investigated further for its advantages over the conventional techniques in terms of efficacy, applicability and cost. The aim of the proposed project is to carry out an experimental campaign to provide the essential experimental background to introduce and validate the effectiveness of this technology when repeated earthquake loads are applied several times on a brick masonry structural component. The experiments will be performed at the testing facilities of BuildinG, partner of the project, and will be supervised by members of the Earthquake Research Group of Hanze University of Applied Sciences.
