Background Children with speech sound disorders (SSD) are at higher risk of communication breakdown, but the impact of having an SSD may vary from child to child. Determining the severity of SSD helps speech-language therapists (SLTs) to recognise the extent of the problem and to identify and prioritise children who require intervention. Aims This study aimed to identify severity factors for SSD in order to develop a multifactorial Speech Sound Disorder Severity Construct (SSDSC) using SLTs’ views and the International Classification of Functioning, Disability and Health (ICF). Method In an explorative five-staged qualitative study, the research question was answered: ‘How do SLTs determine the severity of SSD in children?’. A total of 91 SLTs from The Netherlands participated in data collection and analysis. The iterative process included three different qualitative research methodologies (thematic analysis [TA], constructivist grounded theory [CGT] and content analysis [CA]) to ensure validation of the results by means of method triangulation. Results SLTs considered nine themes: intelligibility, speech accuracy, persistence, the child's perception, impact, communicative participation, concomitant factors, professional point of view, and environmental factors. The themes were summarised in three main severity factors: (I) Speech accuracy, (II) The child's perception of the impact of their speech, and (III) Intelligibility in communication. Other severity factors were concomitant factors and impact. Expertise and support were identified as facilitators or barriers that may worsen or relieve the severity of SSD. Conclusions This study highlights the need for SLTs to rethink how they think about severity as a simplistic construct reflecting only speech accuracy. It is recommended that a broader holistic approach to measuring severity is adopted.

The interplay between sound and vision is a key determinant of human perception. With the development of Virtual Reality (VR) technologies and their commercial applications, there is emergent need to better understand how audio-visual signals manipulated in virtual environments influence perception and human behaviour. The current study addresses this challenge in simulated VR environments mirroring real life scenarios. In particular, we investigated the parameters that might enhance perception, and thus VR experiences when sound and vision are manipulated. A VR museum was created mimicking a real art gallery featuring Japanese paintings. Participants were exposed to the gallery via Samsung Gear VR, head mounted display, and could freely walk in. To half of the participants newly composed music clips were played, during the VR gallery visit. The other participants were exposed to the same environment, but no music was played (control condition). The results showed that music played altered the way people are engaged in, perceive and experience the VR art gallery. Opposite to our expectation, the VR experience was liked more when no music was played. The naturalness and presence were perceived to be relatively high, and did not differ significantly depending on whether music was played or not. Regression modelling further explored the relationship between the parameters hypothesised to influence the VR experiences. The findings are summarised in a theoretical model. The study outcomes could be implemented to successfully develop efficient VR applications for art and entertainment.

A substantial amount of studies have addressed the influence of sound on human performance. In many of these, however, the large acoustic differences between experimental conditions prevent a direct translation of the results to realistic effects of room acoustic interventions. This review identifies those studies which can be, in principle, translated to (changes in) room acoustic parameters and adds to the knowledge about the influence of the indoor sound environment on people. The review procedure is based on the effect room acoustics can have on the relevant quantifiers of the sound environment in a room or space. 272 papers containing empirical findings on the influence of sound or noise on some measure of human performance were found. Of these, only 12 papers complied with this review's criteria. A conceptual framework is suggested based on the analysis of results, positioning the role of room acoustics in the influence of sound on task performance. Furthermore, valuable insights are pre- sented that can be used in future studies on this topic. Whi le the influence of the sound environment on performance is clearly an issue in many situations, evidence regarding the effectiveness of strategies to control the sound environment by room acoustic design is lacking and should be a focus area in future studies.

Denim Democracy from the Alliance for Responsible Denim (ARD) is an interactive exhibition that celebrates the journey and learning of ARD members, educates visitors about sustainable denim and highlights how companies collaborate together to achieve results. Through sight, sound and tactile sensations, the visitor experiences and fully engages sustainable denim production. The exhibition launches in October 2018 in Amsterdam and travels to key venues and locations in the Netherlands until April 2019. As consumers, we love denim but the denim industry, like other sub-sectors in the textile, apparel and footwear industries, faces many complex sustainability challenges and has been criticized for its polluting and hazardous production practices. The Alliance for Responsible Denim project brought leading denim brands, suppliers and stakeholders together to collectively address these issues and take initial steps towards improving the ecological sustainability impact of denim production. Sustainability challenges are considered very complex and economically undesirable for individual companies to address alone. In denim, small and medium sized denim firms face specific challenges, such as lower economies of scale and lower buying power to affect change in practices. There is great benefit in combining denim companies' resources and knowledge so that collective experimentation and learning can lift the sustainability standards of the industry and lead to the development of common standards and benchmarks on a scale that matters. If meaningful, transformative industrial change is to be made, then it calls for collaboration between denim industry stakeholders that goes beyond supplier-buyer relations and includes horizontal value chain collaboration of competing large and small denim brands. However collaboration between organizations, and especially between competitors, is highly complex and prone to failure. The research behind the Alliance for Responsible Denim project asked a central research question: how do competitors effectively collaborate together to create common, industry standards on resource use and benchmarks for improved ecological sustainability? To answer this question, we used a mixed-method, action research approach. The Alliance for Responsible Denim project mobilized and facilitated denim brands to collectively identify ways to reduce the use of water and chemicals in denim production and then aided them to implement these practices individually in their respective firms.
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.
Het project ‘Data Resonantie’ is een artistiek onderzoeksproject bedoeld om met behulp van moderne technologieën en persoonlijke data nieuwe manieren te ontdekken om in coronatijd veilige, gedeelde openbare ruimtes te creëren. Het onderzoek wil bijdragen aan de ontwikkeling van zowel praktische toepassingen als vernieuwende artistieke methodes in het veld van Mens Machine Interactie op het gebied van veiligheid en privacy in openbare ruimtes waar veel mensen komen en waardoor afstand houden ingewikkeld is. Dat gebeurt in de setting van een aantal labs waarin met persoonlijke data via real-time surveillance een audiovisuele ervaring wordt gegenereerd die participanten een veilige afstand toont, ze laat bijdragen aan de soundscape en ze tegelijkertijd mogelijk bewuster maakt van kwesties rondom het gebruik van persoonlijke data. In de respectievelijke labs zal gebruik worden gemaakt van de expertise van de betrokken partners op het gebied van artistiek onderzoek (Artistic Research Community/Frank Mohr Instituut), experimenteel artistieke settings (Re:Search:Gallery), geluidsresonantie (STEIN) en het gebruik van drones (Omnidones). De centrale vraagstelling is: Hoe kan een artistieke-technisch systeem, dat met behulp van een drone persoonlijke data vertaalt in sensorische ervaringen, individuen in staat stellen om door afstand te houden van elkaar een veilig gedeelde omgeving te co-creëren? Het project is een kruisbestuiving en interdisciplinaire samenwerking tussen een aantal verschillende organisaties in Noord-Nederland; Het is een voorbeeld van de wijze waarop artistiek onderzoekers met een hybride methodologie en met gebruikmaking van verschillende disciplines en expertises ingewikkelde maatschappelijke problemen ter hand kunnen nemen. Daarnaast resulteert het in nieuwe publieke toepassingen voor drone en audio technologieën met de potentie een uitweg te bieden aan sectoren die te lijden hebben onder de corona maatregelen, met in het bijzonder de evenementen industrie en de ermee verbonden horeca en retail.
