Although creativity is often seen as requiring spontaneity and flexibility, recent work suggests that there is creative potential in a structured and systematic approach as well. In a series of four experiments, we show that when Personal Need for Structure (PNS) is high, either chronic (Study 1) or situationally induced (Study 2), creative performance benefits from high task structure. Further, in line with earlier work on cognitive fixation effects, we show that when high task structure contains an example of noncreative task execution, creative performance is impaired, regardless of individuals' PNS. Nevertheless, participants high in PNS react relatively favorably to high task structure (Study 3) and are more likely to adopt a structured task approach when given the choice (Study 4). In sum, our results show that task structure can both stimulate and inhibit creative performance, particularly for people high in need for structure. © 2014 John Wiley & Sons, Ltd.
Collaborative learning tasks may represent an effective way to stimulate higher-order processes among high-ability students in regular classrooms. This study investigatedthe effects of task structure and group composition on the elaboration and metacognitive activities of 11th grade preuniversity students during a collaborative learning task: 102 students worked in small groups. On an ill-structured or moderately structured task. Differential effects forcognitive ability were investigated using a continuous measure. Likewise, the effects of group composition were examined using a continuous measure of the cognitiveheterogeneity of the group. The group dialogues were transcribed and coded. Analysis revealed an interaction effect between task structure and cognitive abilityon students’ elaboration and metacognitive activities. Task structure had a negative effect on the elaborative contributions of high-ability students. For students with lower abilities, task structure had a positive effect onelaboration and metacognitive activities. No effects were found of the cognitive heterogeneity of the group. Group composition seemed not to be related to group interactionamong 11th grade pre-university students. The results indicate that open-ended collaborative tasks with little guidance and directions on how to handle them, canstimulate higher-order processes among high-ability students and may offer them the challenge they need.

Het doel van dit proefschrift betrof het verkennen van attituden en afwegingen rond taakherschikking tussen tandartsen en mondhygiënisten. Daarnaast werd nagegaan welke sociale kenmerken studenten toeschrijven aan elkaar, zichzelf en beide beroepsgroepen. Vervolgens werd het effect van een psychologische interventie in een onderwijssetting onderzocht op interprofessionele communicatie en percepties ten aanzien van interprofessionele taakverdeling. Tandartsen en mondhygiënisten hebben verschillende attituden ten opzichte van taakherschikking, vooral wat betreft de vrijgevestigde praktijk van mondhygiënisten. Dit laatste wordt het minst gewenst door tandartsen. Tandartsen en mondhygiënisten hebben verschillende afwegingen wanneer men een voor- of tegenstander is van dit beleid. De interprofessionele relatie tussen tandartsen en mondhygiënisten komt tot uiting in de attributie van specifieke sociale kenmerken. Tandheelkunde en mondzorgkunde studenten zijn beide de mening toegedaan dat tandartsen meer dominant zijn dan mondhygiënisten. Het faciliteren van interprofessionele groepsvorming kan zowel interprofessionele hiërarchie als tandarts-gecentreerde taakverdeling reduceren. Tijdens het eerste onderzoek (Hoofdstuk 2) werden verschillen tussen tandartsen en mondhygiënisten ontdekt ten aanzien van de taakuitbreiding van de mondhygiënist. De helft van alle tandartsen en de meeste mondhygiënisten hebben hierover een positieve attitude. Een interprofessionele kloof werd gevonden ten aanzien van de zelfstandige praktijkvoering van mondhygiënisten. Een minderheid van alle tandartsen heeft hierover een positieve attitude vergeleken met een meerderheid van alle mondhygiënisten. Dit suggereert dat de acceptatie van een zelfstandige mondhygiënist een groot obstakel is wanneer men taakherschikking wil implementeren. Tandartsen willen controle over de mondhygiënist behouden, daarom is het waarschijnlijk dat taakdelegatie boven taaksubstitutie wordt verkozen. Dit laatste betreft taakherschikking met professionele autonomie.
Structural colour (SC) is created by light interacting with regular nanostructures in angle-dependent ways resulting in vivid hues. This form of intense colouration offers commercial and industrial benefits over dyes and other pigments. Advantages include durability, efficient use of light, anti-fade properties and the potential to be created from low cost materials (e.g. cellulose fibres). SC is widely found in nature, examples include butterflies, squid, beetles, plants and even bacteria. Flavobacterium IR1 is a Gram-negative, gliding bacterium isolated from Rotterdam harbour. IR1 is able to rapidly self-assemble into a 2D photonic crystal (a form of SC) on hydrated surfaces. Colonies of IR1 are able to display intense, angle-dependent colours when illuminated with white light. The process of assembly from a disordered structure to intense hues, that reflect the ordering of the cells, is possible within 10-20 minutes. This bacterium can be stored long-term by freeze drying and then rapidly activated by hydration. We see these properties as suiting a cellular reporter system quite distinct from those on the market, SC is intended to be “the new Green Fluorescent Protein”. The ability to understand the genomics and genetics of SC is the unique selling point to be exploited in product development. We propose exploiting SC in IR1 to create microbial biosensors to detect, in the first instance, volatile compounds that are damaging to health and the environment over the long term. Examples include petroleum or plastic derivatives that cause cancer, birth defects and allergies, indicate explosives or other insidious hazards. Hoekmine, working with staff and students within the Hogeschool Utrecht and iLab, has developed the tools to do these tasks. We intend to create a freeze-dried disposable product (disposables) that, when rehydrated, allow IR1 strains to sense and report multiple hazardous vapours alerting industries and individuals to threats. The data, visible as brightly coloured patches of bacteria, will be captured and quantified by mobile phone creating a system that can be used in any location by any user without prior training. Access to advice, assay results and other information will be via a custom designed APP. This work will be performed in parallel with the creation of a business plan and market/IP investigation to prepare the ground for seed investment. The vision is to make a widely usable series of tests to allow robust environmental monitoring for all to improve the quality of life. In the future, this technology will be applied to other areas of diagnostics.
The objective of DIGIREAL-XL is to build a Research, Development & Innovation (RD&I) Center (SPRONG GROUP, level 4) on Digital Realities (DR) for Societal-Economic Impact. DR are intelligent, interactive, and immersive digital environments that seamlessly integrate Data, Artificial Intelligence/Machine Learning, Modelling-Simulation, and Visualization by using Game and Media Technologies (Game platforms/VR/AR/MR). Examples of these DR disruptive innovations can be seen in many domains, such as in the entertainment and service industries (Digital Humans); in the entertainment, leisure, learning, and culture domain (Virtual Museums and Music festivals) and within the decision making and spatial planning domain (Digital Twins). There are many well-recognized innovations in each of the enabling technologies (Data, AI,V/AR). However, DIGIREAL-XL goes beyond these disconnected state-of-the-art developments and technologies in its focus on DR as an integrated socio-technical concept. This requires pre-commercial, interdisciplinary RD&I, in cross-sectoral and inter-organizational networks. There is a need for integrating theories, methodologies, smart tools, and cross-disciplinary field labs for the effective and efficient design and production of DR. In doing so, DIGIREAL-XL addresses the challenges formulated under the KIA-Enabling Technologies / Key Methodologies for sectoral and societal transformation. BUas (lead partner) and FONTYS built a SPRONG group level 4 based on four pillars: RD&I-Program, Field Labs, Lab-Infrastructure, and Organizational Excellence Program. This provides a solid foundation to initiate and execute challenging, externally funded RD&I projects with partners in SPRONG stage one ('21-'25) and beyond (until' 29). DIGIREAL-XL is organized in a coherent set of Work Packages with clear objectives, tasks, deliverables, and milestones. The SPRONG group is well-positioned within the emerging MINDLABS Interactive Technologies eco-system and strengthens the regional (North-Brabant) digitalization agenda. Field labs on DR work with support and co-funding by many network organizations such as Digishape and Chronosphere and public, private, and societal organizations.
