Background: Despite the increasing attention for the positive effects of physical activity (PA), nearly half of the Dutch citizens do not meet the national PA guidelines. A promising method for increasing PA are mobile exercise applications (apps), especially if they are embedded with theoretically supported persuasive strategies (e.g., goal setting and feedback) that align with the needs and wishes of the user. In addition, it is argued that the operationalization of the persuasive strategies could increase the effectiveness of the app, such as the actual content or visualization of feedback. Although much research has been done to examine the preferences for persuasive strategies, little is known about the needs, wishes, and preferences for the design and operationalization of persuasive strategies.Objective: The purpose of this study was to get insight in the needs, wishes, and preferences regarding the practical operationalization of persuasive strategies in a mobile application aimed at promoting PA in healthy inactive adults.Methods: Five semistructured focus groups were performed. During the focus groups, the participants were led into a discussion about the design and operationalization of six predefined theory-based persuasive strategies (e.g., self-monitoring, feedback, goal setting, reminders, rewards, and social support) directed by two moderators. The audio-recorded focus groups were transcribed verbatim and analyzed following the framework approach.Results: Eight men and 17 women between 35 and 55 years (mean age, 49.2) participated in the study. Outcomes demonstrated diverse preferences for implementation types and design characteristics of persuasive strategies in mobile applications. Basic statistics (such as distance, time and calories), positive feedback based on easy-to-achieve goals that relate to health guidelines, and motivating reminders on a relevant moment were preferred. Participants had mixed preferences regarding rewards and a social platform to invite other users to join PA.Conclusions: Findings indicated that in mHealth applications for healthy but inactive adults, persuasive strategies should be designed and implemented in a way that they relate to health guidelines. Moreover, there is a need for an app that can be adapted or can learn based on personal preferences as, for example, preferences with regard to timing of feedback and reminders differed between people.
Public transgressions by group members threaten the public image of a group when outside observers perceive them as representative of the group in general. In three studies, we tested the effectiveness of rejection of a deviant group member who made a racist comment in public, and compared this to several other strategies the group could employ to protect their image. In Study 1 (N¼75) and Study 2 (N¼51), the group was judged less racist after rejecting the deviant than after claiming a non-racist position or not responding to the transgression. Perceived typicality of the deviant partially mediated this effect in Study 2. In Study 3 (N¼81), the group was judged least racist after forcing the deviant to apologize and as most racist after denying the severity of the transgression. Results also showed a negative side-effect of rejection. Perceived exclusion of the deviant contributed to a perception of the group as disloyal to its members, which resulted in a less favorable overall group evaluation. Potential benefits and risks of rejection, denial, and apologies are further discussed in the General Discussion.
AbstractThis study assessed the efficacy of a co-designed, school-based intervention meant to promote physical activityand fitness among Dutch prevocational secondary students. In a two-year clustered randomized controlled trial,students’ physical activity and fitness was measured by indirect and direct methods. In the intervention group,we used the triple-I procedure, a participatory action research method, to co-design the intervention together withthe students and schools. This procedure involved focus group discussions by interviewing and imagingtechniques, followed by a co-design process to align the intervention content and implementation processes withstudents’ preferences. The study involved 22 Dutch schools, with a total of 2685 13-to-14-year-old prevocationalsecondary students. Schools were randomly assigned to either intervention (11 schools, 1446 students) or controlgroup (11 schools, 1239 students).There were no significant intervention differences between students’ overallphysical activity behavior on intervention versus control schools. However, with regards to various specificphysical fitness indicators, such as the long jump, handgrip strength, shuttle run test, and the sum of skinfolds,intervention school students performed significantly better than the control group students. Furthermore, whentaking into account student participation, i.e. the success of the co-design process, schools with higher levels ofstudent participation showed higher shuttle run scores. However, such graded effects were not similarly apparentwith regards to students’ physical fitness indicators. This study showed that co-designing a comprehensivephysical activity intervention on numerous Dutch high schools via the Triple-I Interactive Method was feasible.Moreover, results showed that certain aspects of physical fitness were improved after two years of intervention,although taken together with the lack of effects on physical activity, results were mixed.
In this project we utilize the conversational model of delivering destination information as an experimental intervention to provide tips to a sub-group of visitor participants in one specific destination, Overijssel. By contrasting the experience of this group to a randomly assigned control group will be able to test the effectiveness of hyper-personalized information. Furthermore, we will investigate the effectiveness of integrating, in the tips provided, the policy of the DMO to direct visitors to certain places while reducing the pressure on others. For this variable as well––policy-driven vs. demand-driven information sources––random assignment to test and control groups will allow us to draw conclusions about causes of differences in tourist behavior and experience.The main question is: Does the conversational information model, as exemplified by Travel with Zoey, create the possibility to direct people to the places destination managers would like them to go, while assuring they benefit equally––or even more–from their travel experience?

Het Hanze Innovation Traineeship Pilot project is geïnitieerd op de Hanzehogeschool Groningen door drie onderzoeksgroepen (lectoraten) die zijn ingebed in het Marian van Os Centre of Expertise Ondernemen (CoEO). De trainees worden gecoacht in een Community of Learners en begeleid door een diverse groep van onderzoekers van de volgende onderzoeksgroepen van de Hanzehogeschool Groningen: (1) International Business, (2) Marketing/Marktgericht Ondernemen en (3) User-Centered Design. Het doel van het programma is om regionale MKBs in Noord-Nederland te ondersteunen om duurzaam te innoveren met de hulp en ondersteuning van trainees en onderzoekers van de drie onderzoeksgroepen. De trainees worden begeleid bij het ontwikkelen en implementeren van een door onderzoek ondersteunde innovatie tijdens een afstudeerproject en een 12-maanden durende traineeship bij het bedrijf. Bij de start van het programma ondergaan de MKBs een innovatie-gezondheids-check die wordt herhaald nadat de traineeship is afgerond. Over het algemeen zouden de bedrijven hun bedrijfsprestaties en innovatiecapaciteit moeten kunnen verbeteren door middel van het programma. Verder zal de onderzoekssamenwerking tussen de onderzoeksgroepen van de Hanzehogeschool en de MKBs leiden tot een beter inzicht in innovatiebarrières en succesfactoren. De opgedane kennis over regionale MKB-innovatie zal in alle sectoren en industrieën worden geprojecteerd. De uiteindelijke projectresultaten zullen dienen voor het besluitvormingsproces van toekomstige innovatie traineeship programma's
Introduction The research group Biobased Resources & Energy (BRE) of Avans focusses on recovery of valuable building blocks from low-value solid and liquid residual streams from agriculture, households and industries. For the valorisation of these residual streams, BRE looks into different biological, chemical and mechanical processes. One of the main issues in the utilisation of residual streams is economic feasibility and the recovery of multiple resources from one residual stream. Using membrane technologies in combination with biological, chemical and/or mechanical processes could offer great opportunities. Central Research Question What is the applicability of membrane technologies for valorisation of different residual streams and is it possible to integrate membrane technology in current and new biorefining projects of research group BRE: Set-up In order to reach the goal of this postdoc, 4 research questions will be answered using literature search, experimentation and modelling: 1) What membrane methods are currently (commercially) available to enhance the results of current projects in research group BRE? 2) What are the essential technical parameters for membrane separation and how can these be optimized? 3) What is the economic impact of using membrane technology in recovery of valuable building blocks from residual streams? 4) What are the effects of using membranes instead of or complementary to currently used methods on the sustainability of valorisation of residual streams? Cooperation The postdoc and the research group BRE want to extend the contact and research cooperation with (regional) businesses and (applied) universities and support and facilitate the introduction and further development of membrane technologies in the curriculum of different Avans study programmes. This will be done via internships, minor projects (together with businesses) and development of study material for courses and trainings.
