Diadema sea-urchins play a vital role in maintaining a balanced coral reef ecosystem by grazing away algae and creating bare substrate for coral recruitment. The RAAKPRO Diadema project aims to develop interventions to improve larval recruitment and juvenile survival to increase local Diadema populations. To do this, researchers are investigating the larval and settlement stage of Diadema populations around the islands of Saba and St. Eustatius. First results show that some locations have a high suitability for “assisted natural recovery”.

Met deze paper willen we recht doen aan deze omissie. Na een uiteen-zetting van wat te verstaan onder vakmanschap van re-integratie-dienstverlening besteden we aandacht aan drie generieke vaardigheden die we in onze onderzoeken zijn tegengekomen. We illustreren dit aan de hand van onderzoek naar dienstverlening aan werkzoekenden en aan werkgevers. We ronden de paper af met een uiteenzetting over hoe de generieke vaardigheden een plek kunnen krijgen in scholing en professionalisering.

This document consists of the research report of Work Package 3 of ProMiMiC's locations Groningen and The Hague. Through the implementation of MiMiC-projects in the form of ‘living labs’, research data was generated leading to insights into (1) concepts of interprofessionality between musicians and healthcare professionals, (2) effects of the MiMiC-practice on nurses’ compassionate skills in contact with patients and (3) the influence of the various contexts on the MiMiC-practice. Given the fact that hospitals are the site of study in ProMiMiC, the research activities of Work Package 3 got highly affected by the COVID-19 pandemic. It led to additional questions and expansion of the MiMiC practice to directions that the consortium hadnot foreseen.--- Update September 2025: Chapter 5 - episodes added as a separate file for open access.

Introduction: Sensor-feedback systems can be used to support people after stroke during independent practice of gait. The main aim of the study was to describe the user-centred approach to (re)design the user interface of the sensor feedback system “Stappy” for people after stroke, and share the deliverables and key observations from this process. Methods: The user-centred approach was structured around four phases (the discovery, definition, development and delivery phase) which were fundamental to the design process. Fifteen participants with cognitive and/or physical limitations participated (10 women, 2/3 older than 65). Prototypes were evaluated in multiple test rounds, consisting of 2–7 individual test sessions. Results: Seven deliverables were created: a list of design requirements, a personae, a user flow, a low-, medium- and high-fidelity prototype and the character “Stappy”. The first six deliverables were necessary tools to design the user interface, whereas the character was a solution resulting from this design process. Key observations related to “readability and contrast of visual information”, “understanding and remembering information”, “physical limitations” were confirmed by and “empathy” was additionally derived from the design process. Conclusions: The study offers a structured methodology resulting in deliverables and key observations, which can be used to (re)design meaningful user interfaces for people after stroke. Additionally, the study provides a technique that may promote “empathy” through the creation of the character Stappy. The description may provide guidance for health care professionals, researchers or designers in future user interface design projects in which existing products are redesigned for people after stroke.

Objectives: To investigate immediate changes in walking performance associated with three implicit motor learning strategies and to explore patient experiences of each strategy. Design: Participants were randomly allocated to one of three implicit motor learning strategies. Within-group comparisons of spatiotemporal parameters at baseline and post strategy were performed. Setting: Laboratory setting. Subjects: A total of 56 community-dwelling post-stroke individuals. Interventions: Implicit learning strategies were analogy instructions, environmental constraints and action observation. Different analogy instructions and environmental constraints were used to facilitate specific gait parameters. Within action observation, only videotaped gait was shown. Main measures: Spatiotemporal measures (speed, step length, step width, step height) were recorded using Vicon 3D motion analysis. Patient experiences were assessed by questionnaire. Results: At a group level, three of the four analogy instructions (n=19) led to small but significant changes in speed (d=0.088m/s), step height (affected side d=0.006m) and step width (d=–0.019m), and one environmental constraint (n=17) led to significant changes in step width (d=–0.040m). At an individual level, results showed wide variation in the magnitude of changes. Within action observation (n=20), no significant changes were found. Overall, participants found it easy to use the different strategies and experienced some changes in their walking performance. Conclusion: Analogy instructions and environmental constraints can lead to specific, immediate changes in the walking performance and were in general experienced as feasible by the participants. However, the response of an individual patient may vary quite considerably.

Objective. Clinicians may use implicit or explicit motor learning approaches to facilitatemotor learning of patients with stroke. Implicit motor learning approaches have shown promising results in healthy populations. The purpose of this study was to assess whether an implicit motor learning walking intervention is more effective compared with an explicit motor learning walking intervention delivered at home regarding walking speed in people after stroke in the chronic phase of recovery. Methods. This randomized, controlled, single-blind trial was conducted in the home environment. The 79 participants, who were in the chronic phase after stroke (age = 66.4 [SD = 11.0] years; time poststroke = 70.1 [SD = 64.3] months; walking speed = 0.7 [SD = 0.3] m/s; Berg Balance Scale score = 44.5 [SD = 9.5]), were randomly assigned to an implicit (n = 38) or explicit (n = 41) group. Analogy learning was used as the implicit motor learning walking intervention, whereas the explicit motor learning walking intervention consisted of detailed verbal instructions. Both groups received 9 training sessions (30 minutes each), for a period of 3 weeks, targeted at improving quality of walking. The primary outcome was walking speed measured by the 10-MeterWalk Test at a comfortable walking pace. Outcomes were assessed at baseline, immediately after intervention, and 1 month postintervention. Results. No statistically or clinically relevant differences between groups were obtained postintervention (between-group difference was estimated at 0.02 m/s [95% CI = −0.04 to 0.08] and at follow-up (between-group difference estimated at −0.02 m/s [95% CI = −0.09 to 0.05]). Conclusion. Implicit motor learning was not superior to explicit motor learning to improve walking speed in people after stroke in the chronic phase of recovery. Impact. To our knowledge, this is the first study to examine the effects of implicit compared with explicit motor learning on a functional task in people after stroke. Results indicate that physical therapists can use (tailored) implicit and explicit motor learning strategies to improve walking speed in people after stroke who are in the chronic phase of recovery.

Het lectoraat Energietransitie van EnTranCe, het Centre of Expertise Energyvan de Hanzehogeschool Groningen, richt zich op de systeemverandering dienodig is om de Energietransitie vorm te geven. Een systeemverandering, wantde energietransitie is meer dan het vervangen van centrales door windmolens enzonnepanelen. Het vraagt, naast technologische veranderingen, ook veranderingen binnen het sociaal-economische stelsel.Onze maatschappij is verslaafd aan energie en aan het gegeven dat het altijdonbeperkt beschikbaar is. Willen wij onze standaard van leven kunnen handhaven, dan moeten we bereid zijn om zaken aan te passen. Na de tweede wereldoorlog heeft onze energievoorziening zich sterk gecentraliseerd ontwikkeld, met grote partijen en infrastructuur (macro) die daar de regie op hebben. De groeiende wens vanuit de samenleving om zelf keuzes te kunnen maken in het gebied dat mensen zelf kunnen beïnvloeden (micro) zorgt voor een sterke ‘bottom up’ beweging rondom verduurzaming. In onze visie zullen de belangrijkste doorbraken rond de transitie nodig zijn daar waar de macro- en micro ontwikkelingen elkaar raken: het meso niveau. Hier is het dat het transitieproces zich het sterkst zal manifesteren. De onderzoekslijn ‘De rol van waterstof binnen de energietransitie’ binnen dit lectoraat richt zich dan ook op mogelijke productie en toepassingen van duurzame waterstof op dit mesoniveau. Het niveau van een dorp, een wijk , een blok huizen of een bedrijf. Ook hier kijken we naar de verandering van het gehele systeem: optechnologieniveau, de integratie met het macrosysteem, de mens, economie ende juridische praktijk. Samenwerking met andere lectoraten is dan ook van grootbelang.

Control of plant growth is an important aspect of crop productivity and yield in agriculture. Overexpression of the At CHR12/ 23 genes in Arabidopsis thaliana reduced growth habit without other morphological changes. These two genes encode Snf2 chromatin remodelling ATPases. Here, we translate this approach to the horticultural crop tomato ( Solanum lycopersicum). We identified and cloned the single tomato ortholog of the two Arabidopsis Snf2 genes, designated Sl CHR1. Transgenic tomato plants (cv. Micro-Tom) that constitutively overexpress the coding sequence of Sl CHR1 show reduced growth in all developmental stages of tomato. This confirms that Sl CHR1 combines the functions of both Arabidopsis genes in tomato. Compared to the wild type, the transgenic seedlings of tomato have significantly shorter roots, hypocotyls and reduced cotyledon size. Transgenic plants have a much more compact growth habit with markedly reduced plant height, severely compacted reproductive structures with smaller flowers and smaller fruits. The results indicate that either GMO-based or non- GMO-based approaches to modulate the expression of chromatin remodelling ATPase genes could develop into methods to control plant growth, for example to replace the use of chemical growth retardants. This approach is likely to be applicable and attractive for any crop for which growth habit reduction has added value.
