Background Anxiety and challenging behaviour (CB) often occur simultaneously in people with intellectual disabilities (ID). Understanding the associations between anxiety and CB may contribute to more accurate diagnoses and management of both anxiety and CB in this population. Aims To examine the relationship between anxiety and CB. Methods A literature review covering the period from January 2000 to January 2012. Results Seven studies about the relationship between psychiatric disorders, including anxiety, and CB were identified. These studies confirm the relationship between anxiety and CB in people with ID, although the precise nature of this relationship remains unclear. Conclusions The study points toward the existence of a moderate association between anxiety and CB. Further research is needed to clarify the complex nature of the association between anxiety and CB.

Aim. This study aims to identify ways that allow studying how intellectually impaired persons showing challenging behaviour interact with space, without impacting their daily lives. Back-ground. Research about space that better suits these persons’ needs is challenging to conduct, since they may have difficulties expressing themselves verbally and are extremely sensitive to-wards sensory stimuli. Therefore, researchers collecting data may be disturbing and intrusive, and requires great caution. Tapping into existing data may be a promising alternative. Residential care organisations routinely collect data about residents during their regular work processes, such as personal information and incident registration. Also useful may be routinely collected spatial data, such as drawings and repair reports. This study explores how routinely collected data (RCD) can provide insight into how residents interact with space, without impacting their daily lives. Methods. We reflect on the possibilities of using RCD (related to resident or space) based on explorations in the context of a case study at a Dutch very-intensive-care facility. The data were analysed to identify general patterns, such as locations with a high density of incidents/repairs and verified initial findings by member checking with staff. Results. The RCD analysed provide a basic and relevant insight into incidents and repairs connected to challenging behaviour. However, most data were neither complete or relevant for analysis. Therefore, we dis-cussed the RCD were with staff and only then it was possible to draw conclusions regarding relevance of RCD and the residents-space interactions. Conclusions. Only in conjunction with an ex-tended approach on member checking the use of RCD seems relevant. RCD have little meaning of their own. But the combination of RCD with member checking seems to provide insight into the interaction between residents and space, without interfering with the residents’ daily lives.

BACKGROUND: The care sector for persons with disabilities considers the physical environment relevant for the quality of life of people with intellectual disabilities. However, scientific evidence is limited. OBJECTIVE: To obtain evidence regarding comforting and encouraging environments and to develop an overview of studies addressing the effect of the physical environment on people with intellectual disabilities. METHODS: A scoping review, accompanied by expert panels and case findings combining scientific evidence and knowledge from practice, was performed to investigate the interaction between challenging behaviour and the physical environment. Between January and March 2020, several scientific databases were searched in the English, Dutch, and German language for relevant studies. Social media, care professionals, and experts in building physics were consulted. RESULTS: Studies on building-related factors as passive interventions and care- or therapy-related interventions could be distinguished. The majority of the studies report on building-related factors such as sound, acoustics, light, and colours and their influence on behaviour. Specific guidelines are lacking on how to adjust the indoor environment to an environment that is safe, comforting and encouraging for people displaying challenging behaviour. Proposed solutions are case-based. CONCLUSION: In future studies individual cases could be studied in a more in-depth manner, aligned and categorised to the building-related factors and to the expressions of challenging behaviour.

This PD project aims to gather new knowledge through artistic and participatory design research within neighbourhoods for possible ways of addressing and understanding the avoidance and numbness caused by feelings of vulnerability, discomfort and pain associated with eco-anxiety and chronic fear of environmental doom. The project will include artistic production and suitable forms of fieldwork. The objectives of the PD are to find answers to the practice problem of society which call for art that sensitises, makes aware and helps initiate behavioural change around the consequences of climate change. Rather than visualize future sea levels directly, it will seek to engage with climate change in a metaphorical and poetic way. Neither a doom nor an overly techno-optimistic scenario seem useful to understand the complexity of flood risk management or the dangers of flooding. By challenging both perspectives with artistic means, this research hopes to counter eco-anxiety and create a sense of open thought and susceptibility to new ideas, feelings and chains of thought. Animation and humour, are possible ingredients. The objective is to find and create multiple Dutch water stories, not just one. To achieve this, it is necessary to develop new methods for selecting and repurposing existing impactful stories and strong images. Citizens and students will be included to do so via fieldwork. In addition, archival materials will be used. Archives serve as a repository for memory recollection and reuse, selecting material from the audiovisual archive of the Institute of Sound & Vision will be a crucial part of the creative work which will include two films and accompanying music.
The consistent demand for improving products working in a real-time environment is increasing, given the rise in system complexity and urge to constantly optimize the system. One such problem faced by the component supplier is to ensure their product viability under various conditions. Suppliers are at times dependent on the client’s hardware to perform full system level testing and verify own product behaviour under real circumstances. This slows down the development cycle due to dependency on client’s hardware, complexity and safety risks involved with real hardware. Moreover, in the expanding market serving multiple clients with different requirements can be challenging. This is also one of the challenges faced by HyMove, who are the manufacturer of Hydrogen fuel cells module (https://www.hymove.nl/). To match this expectation, it starts with understanding the component behaviour. Hardware in the loop (HIL) is a technique used in development and testing of the real-time systems across various engineering domain. It is a virtual simulation testing method, where a virtual simulation environment, that mimics real-world scenarios, around the physical hardware component is created, allowing for a detailed evaluation of the system’s behaviour. These methods play a vital role in assessing the functionality, robustness and reliability of systems before their deployment. Testing in a controlled environment helps understand system’s behaviour, identify potential issues, reduce risk, refine controls and accelerate the development cycle. The goal is to incorporate the fuel cell system in HIL environment to understand it’s potential in various real-time scenarios for hybrid drivelines and suggest secondary power source sizing, to consolidate appropriate hybridization ratio, along with optimizing the driveline controls. As this is a concept with wider application, this proposal is seen as the starting point for more follow-up research. To this end, a student project is already carried out on steering column as HIL
Environmental nano- and micro-plastics (NMPs) are highly diverse [2]. Accounting for this diversity is one of the main challenges to develop a comprehensive understanding of NMPs detection, quantification, fate, and risks [3]. Two major issues currently limit progresses within this field: (a) validation and broadening the current analytical tools (b) uncertainty with respect to NMPs occurrence and behaviour at small scales (< 20 micron). Tracking NMPs in environmental systems is currently limited to micron size plastics due to the size detection limit of the available analytical techniques. There are currently many uncertainties regarding detecting nanoplastics in real environmental systems, e.g. the inexistence of commercially available NMPs and incompatibility between them and those generated from plastic fragments degradation in the environment. Trying to tackle these problems some research groups synthesized NMPs dopped with metals inside [16]. However, even though elemental analysis techniques (ICP-MS) are rather sensitive, the low volume of these metals encapsulated in the nanoparticles make their detection rather challenging. At the same time, due to Sars-Cov-19 pandemic, nucleic acid identification technologies (LAMP, PCR) experienced a fast evolution and are able to provide detection at very low levels with very compact and reliable equipment. Nuclepar proposes the use of Electrohydrodynamic Atomization (EHDA) to generate NMPs coated with nucleic acids of different polymer types, sizes, and shapes, which can be used as support for detection of such particles using PCR-LAMP technology. If proven possible, Nuclepar might become a first step towards an easy NMPs detection tool. This knowledge will certainly impact current risk assessment tools, efficient interventions to limit emissions and adequate regulations related to NMPs.
