Out-of-plane (OOP) wall collapse is one of the most common failure mechanismsin unreinforced masonry (URM) structures. Insufficient connections at wall-to-wall, wall-to-floor or wall-to-roof levels are one of the main reasons for OOP failures. The seismic assessment of URM buildings with insufficient connections became of high relevance. In particular, cavity walls are widely used in many regions, such as Central and Northern Europe, Australia, New Zealand, China, and Groningen in the Netherlands. Defining thus the behaviour of such connections is of prime importance to understand the overall response of URM buildings.This paper is about an experimental campaign conducted at the BuildinG laboratory of Hanze University of Applied Sciences on timber joist-masonry connections, reproducing cavity walls with timber joists in as-built condition. A total of six URM tests were performed, with varying configurations as: two different tie distributions, two precompression levels and two different as-built connections. The tests aim at providing a complete characterization of the behaviour of the timber-joist cavity-wall connections under axial cyclic loading with special attention on the developed failure mechanism and the definition of force-displacement curves for each group of tests performed. The experimental results show that cohesion and friction between joist and masonry are important parameters in terms of the governing failure mechanism, whether it is a joist-sliding or rocking failure.

Amsterdam is known to be a cosmopolitan and multicultural city where newly arrived migrants find opportunities to test business ideas. Behind every business idea, there are people supporting the entrepreneurs’ initiatives and providing feedback. This chapter examines the role of those people in the process of refining business ideas being implemented in the city. The literature about the role of connections in business highlights the value of networks’ diversity for creativity and innovation. I argue that both diverse and similar business connections have their specific role in the adaptation of a business idea to Amsterdam’s context. The specific role was analyzed from 509 business connections in 41 businesses. Qualitative information and ego network maps were collected to measure similarity indexes in: place of residence, nationality, and level of education of entrepreneurs. The results show that migrant businesses in the multicultural market of Amsterdam rely on diverse and similar connections acting together: similar ones as a safety net where ideas develop and diverse ones where ideas are quickly tested. Migrant entrepreneurs actively use their business connections to carve a niche, whether strengthening relations with migrant-based markets or moving toward the high-end segments of the local market.

Post-earthquake structural damage shows that out-of-plane (OOP) wall collapse is one of the most common failure mechanisms in unreinforced masonry (URM) buildings. This issue is particularly critical in Groningen, a province located in the northern part of the Netherlands, where low-intensity induced earthquakes have become an uprising problem in recent years. The majority of buildings in this area are constructed using URM and were not designed to withstand earthquakes, as the area had never been affected by tectonic seismic activity before. OOP failure in URM structures often stems from poor connections between structural elements, resulting in insufficient restraint to the URM walls. Therefore, investigating the mechanical behaviour of these connections is of prime importance for mitigating damages and collapses in URM structures. This paper presents the results of an experimental campaign conducted on timber joist-masonry cavity wall connections. The specimens consisted of timber joists pocketed into masonry wallets. The campaign aimed at providing a better understanding and characterisation of the cyclic axial behaviour of these connections. Both as-built and strengthened conditions were considered, with different variations, including two tie distributions, two pre-compression levels, two different as-built connections, and one strengthening solution. The experimental findings underscored that incorporating retrofitting bars not only restores the system's initial capacity but also guarantees deformation compatibility between the wall and the joist. This effectively enhances the overall deformation capacity and ductility of the timber joist-cavity wall system.

As the Dutch population is aging, the field of music-in-healthcare keeps expanding. Healthcare, institutionally and at home, is multiprofessional and demands interprofessional collaboration. Musicians are sought-after collaborators in social and healthcare fields, yet lesser-known agents of this multiprofessional group. Although live music supports social-emotional wellbeing and vitality, and nurtures compassionate care delivery, interprofessional collaboration between musicians, social work, and healthcare professionals remains marginal. This limits optimising and integrating music-making in the care. A significant part of this problem is a lack of collaborative transdisciplinary education for music, social, and healthcare students that deep-dives into the development of interprofessional skills. To meet the growing demand for musical collaborations by particularly elderly care organisations, and to innovate musical contributions to the quality of social and healthcare in Northern Netherlands, a transdisciplinary education for music, physiotherapy, and social work studies is needed. This project aims to equip multiprofessional student groups of Hanze with interprofessional skills through co-creative transdisciplinary learning aimed at innovating and improving musical collaborative approaches for working with vulnerable, often older people. The education builds upon experiential learning in Learning LABs, and collaborative project work in real-life care settings, supported by transdisciplinary community forming.The expected outcomes include a new concept of a transdisciplinary education for HBO-curricula, concrete building blocks for a transdisciplinary arts-in-health minor study, innovative student-led approaches for supporting the care and wellbeing of (older) vulnerable people, enhanced integration of musicians in interprofessional care teams, and new interprofessional structures for educational collaboration between music, social work and healthcare faculties.
In recent years, ArtEZ has worked on a broadly supported strategic research agenda on the themes New Ecologies of Matter (ecological challenges), Social Equity (social-societal issues), (Un)Learning Practices (educational innovations) and (Non)CybernEtic Fabric (technological developments). Building on these strategic themes, the ArtEZ Research Collective as developed an international research strategy to become a valuable partner in the relevant Horizon Europe (HEU) areas of Environment, Industry and Social science and humanities. With its specific knowledge position and approach from arts and creativity, ArtEZ is convinced that it can play a distinctive role in European consortia to tackle various challenges in these areas, in particular from the perspective and research topics of the professorships Fashion and Tactical Design. To achieve its ambitions and goals in its targeted research topics, ArtEZ is convinced that a combination of international connections and local applications is key for successful impact. Building upon existing relations and extending the international research position requires extra efforts, e.g., by developing a strong international framework of state-of-the-art research results, impacts and ambitions. Therefore ArtEZ needs to (further) build on both its international network and its supportive infrastructure. With this proposal ArtEZ is presenting its goals and efforts to work on its international recognition as a valuable research partner, and to broaden its international network in cutting-edge research and other stakeholders. With regards to its supporting infrastructure, ArtEZ has the ambition to expand the impact of the Subsidy Desk to become a professional partner to the professorships. This approach requires a further professionalization and extension of both the Subsidy Desk organization and its services, and developing and complementing skills, expertise and competences to comply to the European requirements.
The anterior cruciate ligament (ACL) is a strong rope-like tissue which connects the femur to the tibia in the knee joint. Its function is to provide structural stability to the knee while preventing unnatural forward movement of the tibia relative to the femur. Acute complete ACL ruptures during movements like knee hyperextension or sudden changes of direction (pivoting) damage two entities: the ligament itself and its nerve connections to the posterior tibial nerve (PTN). PTN innervation in the ACL is essential for: a) proprioception (e.g. perception of position and movement/acceleration experienced by the ligament), and b) stability of the knee joint. Upon ACL rupture, the orthopedic surgeon reconstructs the ACL with a graft from the hamstring, patellar or quadriceps tendon. After the surgery, the goal is to regain neuromuscular control and dynamic stabilization during rehabilitation as soon as possible for a quick return to sports and daily activities. However, surgeons are not able to reconstruct the nerve gap between the PTN and the grafted ligament due to the microscopic size of the innervation in the ACL. Not linking the PTN to the graft creates a disconnection between the knee joint and the spinal cord. To mitigate these disadvantages in ACL surgery, this study focuses on activating the growth of proprioception nerve endings using a ligament loaded with growth factors (neurotrophins). We hypothesize that neurotrophins will activate proprioceptive fibers of neurons close to the ACL. We describe graft fabrication steps and in vitro experiments to expand on the regeneration capacity of a commercially available ACL-like synthetic ligament called LARS. The results will bring the ACL regeneration field closer to having a graft that can aid patients in regaining mobility and stability during locomotion and running, confidence in the strength of the knee joint, and quick return to sports.
