Weaving the Feral – Cabinet of Feral Data Curiosities: Living - with Feral Ecologies festival

The installation presents our ongoing investigation of feral ways of knowing, being, and living-with diverse more-than-human ecologies. On display are feral data artifacts such as woven sashes, multispecies tattoos, short dérive films, and an eel trap, all which speak of environmental knowledge and cosmologies in various more-than-human habitats including Colombian chagras, Bohemian forest, Croatian wetlands, and the Gunditjmara Country. Participants are invited to spend time with the artifacts and delve into the stories – of feral relationships and care as well as power and structural inequalities – that they weave together.

Mixed Reality and the Theatre of the Future

The 6th issue of the Fresh Perspectives series takes you on a playful but serious journey along the issues at stake when designing a mixed reality experience in the context of theatre and performance. The publication features a selection of projects describing in detail the artistic design processes, as well as the challenges and opportunities brought about by the use of mixed reality technologies.Joris Weijdom, researcher and lecturer at the Professorship, wrote the key article and curated this publication.

The easier the better?

We often judge things as being more valuable if we have to invest a considerable amount of effort instead of acquiring things effortlessly. Sometimes we can only see the value of things when we lose them. Many studies show that fast scrolling does have a disruptive effect on our understanding. On the other hand, a disruption of our understanding itself is sometimes extremely instructive. For example, the study by Singer and Alexander showed that for very slow readers the learning from the screen was better than learning from paper. An reversed U-shape of optimal learning appears: too little effort results in superficial processing, too much trouble gives poor or no processing at all. An optimum is in the middle, at the top.

Oren voor zangeressen

People with voice problems can seek advice and therapy from a speech-language pathologist. Besides having problems with the speaking voice, a number of them are also amateur choristers. In addition to her standard examination, the speech-language pathologist has to specifically describe the use of the singing voice during choral singing and to assess the amount of mutual influence of speaking and singing voice. In therapy, a healthy phonation is learned. In today's practice, the therapist tends to confine herself to training the sepaking voice. It is known that pitch variation influences phonation. As pitch is a complicating factor in singing, the therapist could make the client aware of this influence by using exercises that alternate speaking and singing voice. Reference to and cooperation with singing teachers is essential. A network of speech-language pathologists 'with an ear for singers' and singing teachers should be built up.

Behavioral quantification of audiomotor transformations in improvising and score-dependent musicians

The historically developed practice of learning to play a music instrument from notes instead of by imitation or improvisation makes it possible to contrast two types of skilled musicians characterized not only by dissimilar performance practices, but also disparate methods of audiomotor learning. In a recent fMRI study comparing these two groups of musicians while they either imagined playing along with a recording or covertly assessed the quality of the performance, we observed activation of a right-hemisphere network of posterior superior parietal and dorsal premotor cortices in improvising musicians, indicating more efficient audiomotor transformation. In the present study, we investigated the detailed performance characteristics underlying the ability of both groups of musicians to replicate music on the basis of aural perception alone. Twenty-two classically trained improvising and score-dependent musicians listened to short, unfamiliar two-part excerpts presented with headphones. They played along or replicated the excerpts by ear on a digital piano, either with or without aural feedback. In addition, they were asked to harmonize or transpose some of the excerpts either to a different key or to the relative minor. MIDI recordings of their performances were compared with recordings of the aural model. Concordance was expressed in an audiomotor alignment score computed with the help of music information retrieval algorithms. Significantly higher alignment scores were found when contrasting groups, voices, and tasks. The present study demonstrates the superior ability of improvising musicians to replicate both the pitch and rhythm of aurally perceived music at the keyboard, not only in the original key, but also in other tonalities. Taken together with the enhanced activation of the right dorsal frontoparietal network found in our previous fMRI study, these results underscore the conclusion that the practice of improvising music can be associated with enhanced audiomotor transformation in response to aurally perceived music.

Met twee benen op de grond kom je geen stap verder (de Opleiding voor Opleiders)

Opleiden is een vak. Een vak waarin mensen en leren centraal staan. Een vak ook dat continu in ontwikkeling is. De opvattingen over opleiden zijn de afgelopen jaren sterk veranderd. Hans Jansen beschrijft in zijn boek Levend Leren (2005) het leerlandschap als alternatief voor het modulegestuurde curriculum. In een curriculum staan de doelen, middelen en inhouden meestal vast, zo ook de volgorde van de themas en de didactische aanpak. Daarmee komt het onderwijzen (de activiteit van de leraar) meer tot zijn recht dan het leren (de activiteit van de student).

A digitally supported home-based exercise training program and dietary protein intervention for community dwelling older adults: protocol of the cluster randomised controlled VITAMIN trial

BackgroundIncreased physical activity and dietary protein intake are promising interventions to prevent or treat the age-related decline in physical performance in older adults. There are well-controlled exercise as well as dietary intervention studies that show beneficial effects on physical performance in older adults. In practice, however, weekly group based exercise or nutritional programs may not be as effective. To optimise these exercise programs for community dwelling older adults, a digitally supported and personalised home-based exercise training program has been designed aiming to improve physical performance in older adults. In addition, a protein intervention in combination with the training program may further improve physical performance in older adults.MethodsThe VITAMIN study will be a cluster randomised controlled trial with three parallel arms. In total, 240 community dwelling older adults (≥ 55 years) participating in weekly group exercise are randomly allocated into: 1) regular weekly exercise program (Control group, n = 80), 2) digitally supported personalised home-based exercise training program group (VITA group, n = 80) and 3) digitally supported personalised home-based exercise training program group plus dietary protein counselling (VITA-Pro group, n = 80). The VITAMIN study aims to evaluate effectiveness of the digitally supported personalised home-based exercise training program as well as the additional value of dietary protein on physical performance after 6 months. In addition, a 12 month follow-up measurement will assess the retaining effect of the interventions. Primary outcome is physical performance measured by the Modified Physical Performance Test (M-PPT) and relevant secondary and observational outcomes include habitual physical activity and dietary intake, body composition, cognitive performance, quality of life, compliance and tablet usage. Data will be analysed by Linear Mixed Models.DiscussionTo our knowledge, the VITAMIN study is the first study that investigates the impact of home-based exercise, protein intake as well as use of persuasive technology in the population of community dwelling older adults.Trial registrationNL56094.029.16 / NTR (TC = 5888; registered 03–06-2016).
