Eating rate is a basic determinant of appetite regulation, as people who eat more slowly feel sated earlier and eat less. Without assistance, eating rate is difficult to modify due to its automatic nature. In the current study, participants used an augmented fork that aimed to decelerate their rate of eating. A total of 114 participants were randomly assigned to the Feedback Condition (FC), in which they received vibrotactile feedback from their fork when eating too fast (i.e., taking more than one bite per 10 s), or a Non-Feedback Condition (NFC). Participants in the FC took fewer bites per minute than did those in the NFC. Participants in the FC also had a higher success ratio, indicating that they had significantly more bites outside the designated time interval of 10 s than did participants in the NFC. A slower eating rate, however, did not lead to a significant reduction in the amount of food consumed or level of satiation.These findings indicate that real-time vibrotactile feedback delivered through an augmented fork is capable of reducing eating rate, but there is no evidence from this study that this reduction in eating rate is translated into an increase in satiation or reduction in food consumption. Overall, this study shows that real-time vibrotactile feedback may be a viable tool in interventions that aim to reduce eating rate. The long-term effectiveness of this form of feedback on satiation and food consumption, however, awaits further investigation.

Fontys, met name de lerarenopleidingen in Tilburg en Eindhoven, voert sinds 1999 een duale opleiding uit ten behoeve van onderwijspersoneel voor het Bve. Bij de ontwikkeling van deze opleiding zijn tien Regionale Opleidingscentra (ROC s) betrokken uit Brabant en Limburg. Studenten beginnen doorgaans niet blanco aan de duale trajecten. Als ze op wat oudere leeftijd instromen, hebben ze vaak al een diversiteit aan scholing en werkervaring achter de rug. Dat verhoogt de noodzaak om vooraf via een intake assessment te onderzoeken over welke relevante eerder verworven competenties de betrokkenen beschikken. Goede intake-assessments leiden uiteindelijk tot flexibilisering in de uitvoering. Bij de invulling van de opleiding wordt met de resultaten rekening gehouden. Diverse medewerkers van Fontys hebben zich met de constructie van een betrouwbaar en valide instrumentarium voor intake-assessment in de duale opleiding beziggehouden. In dit rapport zijn de ervaringen gebundeld en in een breder kader geplaatst.

Habitual behavior is often hard to change because of a lack of self-monitoring skills. Digital technologies offer an unprecedented chance to facilitate self-monitoring by delivering feedback on undesired habitual behavior. This review analyzed the results of 72 studies in which feedback from digital technology attempted to disrupt and change undesired habits. A vast majority of these studies found that feedback through digital technology is an effective way to disrupt habits, regardless of target behavior or feedback technology used.

In het Instituut Archimedes, de tweedegraads lerarenopleiding van de Faculteit Educatie van de Hogeschool Utrecht, neemt de instroom van allochtone studenten toe en daarmee ook de diversiteit van eerder verworven competenties van studenten. Signalen van decanen, docenten, studieloopbaanbegeleiders en onderzoek (Crul &Wolff 2002, Beijer 2005) duiden er op dat relatief veel allochtone studenten problemen ondervinden in hun studieloopbaan. De huidige instrumenten voor intake en studieloopbaanbegeleiding blijken lang niet altijd toereikend te zijn om adequaat de beginsituatie van allochtone studenten vast te stellen en hun studieloopbaan te begeleiden. Er is behoefte aan bijstelling van de bestaande instrumenten en materialen ten behoeve van de veranderende studentenpopulatie. Het Expertisecentrum Diversiteitsbeleid (ECHO) en Sectorbestuur Onderwijs Arbeidsmarkt (SBO) beogen de door- en uitstroom van allochtone studenten in het hoger onderwijs, i.c. de lerarenopleidingen, te verbeteren. Beide organisaties initiëren in samenwerking met hogescholen projecten die een bijdrage leveren aan de verbetering van het onderwijs voor multiculturele studentengroepen. In dit kader hebben ECHO en SBO het Instituut Archimedes het project Intake-assessment en studieloopbaanbegeleiding van allochtone studenten toegekend. Gedurende het studiejaar 2004-2005 hebben studieloopbaanbegeleiders van de opleidingen Frans en Spaans van Instituut Archimedes in samenwerking met een medewerker van de Kenniskring Lesgeven in de Multiculturele School hun ervaringen met de intake en de studieloopbaan van een aantal allochtone studenten in kaart gebracht. De resultaten en aanbevelingen naar aanleiding van de werkzaamheden van de projectgroep staan bij elkaar in dit verslag.

Higher educational institutions incorporate projects into their curricula, in which students, together with educators, researchers and professionals from practice, try to find solutions for real, societal problems, to develop relevant skills. Because such solutions are increasingly digital with high impact on society, ethical responsibility is an important part of these skills. In this study, we analyze two cases of digital innovation projects in higher education in which the concept of the Ethical Matrix is adapted and integrated in a Value Sensitive Design approach and applied by educators (case 1) and by students (case 2). We find that an adapted version of the Ethical Matrix supports educators and students in taking values of different types of stakeholders into account which leads to different design choices.

Summary Purpose The purpose of this study was to investigate the adoption and actual use of a digital dietary monitoring system (DDMS) and its impact on patient satisfaction with the provided hospital care, body weight changes and health-related quality of life (HRQoL) in patients with potentially curable esophageal cancer planned for surgery. The DDMS enables patients and dietitians to monitor patients' nutritional intake and body weight during the preoperative period. Methods In this prospective observational study, the first 47 included patients received usual nutritional care, and were followed from diagnosis until surgery. After implementation of the DDMS 37 patients were followed, again from diagnosis until surgery. Main outcomes were actual use of the DDMS, by means of adoption and usage measures, overall patient satisfaction (EORTC-INPATSAT32), weight change and HRQoL (EORTC QLQ-C30 and EORTC-OG25). Outcomes were assessed immediately after diagnosis, and 6 and 12 weeks later. Results The system had an adoption rate of 64% and a usage rate of 78%. No significant effects on patient satisfaction were found at 12 weeks after diagnosis between the intervention and the usual care group. The implementation of the DDMS also had no significant effect on body weight and HRQoL over time. Conclusions Patients with potentially curable esophageal cancer planned for surgery were able to use the DDMS. However, no significant effects on patient satisfaction, body weight changes and HRQoL were observed. Further research should focus on the specific needs of patients regarding information and support to preoperatively optimize nutritional intake and nutritional status.

Purpose: For prevention of sarcopenia and functional decline in community dwelling older adults, a higher daily protein intake is needed in addition to increased exercise. A new e-health strategy for dietary counseling was usedwith the aim to increase total daily protein intake to optimal levels (minimal 1.2 g/kg/day, optimal 1.5 g/kg/day) through use of regular food products.Methods: The VITAMIN (VITal AMsterdam older adults IN the city) RCT included 245 community dwelling older adults (age ≥ 55y): control, exercise, and exercise plus dietary counseling (protein) group. The dietary counselingintervention was based on behavior change and personalization was offered by a dietitian coach, by use of face-to-face contacts and videoconferencing during a 6-month intervention. Dietary intake was measured by a 3d dietaryrecord at baseline, after 6-month intervention and 12-month follow-up. The primary outcome was average daily protein intake (g/kg/day). Sub-group analysis and secondary outcomes included daily protein distribution, sources,product groups. A Linear Mixed Models (LMM) of repeated measures was performed with STATA v13.Results: Mean age of the 224 subjects was 72.0(6.5) years, a BMI of 26.0(4.2) and 71% were female. The LMM showed a significant effect of time and time*group (p<0.001). The dietary counseling group showed higher protein intakethan either control (1.41 vs 1.13 g/kg/day; β +0.32; p<0.001) or exercise group (1.41 vs 1.11 g/kg/day; β +0.33; p<0.001) after 6-month intervention and 12-month follow-up (1.24 vs 1.05; β +0.23; p<0.001 | 1.24 vs 1.07 β +0.19;p<0.001). Additional analysis revealed the higher protein intake was fully accounted for by animal protein intake.Conclusions: This study shows digitally supported dietary counseling improves protein intake sufficiently incommunity dwelling older adults with use of regular food products. Protein intake increase by personalizedcounseling with e-health is a promising strategy for dietitians with the upcoming rising ageing population.Keywords: Ageing, Behavior change, Nutrition, Physical Functioning, Sarcopenia

Rationale In order to prevent sarcopenia in community dwelling older adults a higher daily protein intake is needed. A new m-health strategy for dietary counseling was used with the aim to increase total daily protein intake to optimal levels (minimal 1.2 g/kg/d, optimal 1.5 g/kg/d) through use of regular food products.Methods The VITAMIN (VITal AMsterdam older adults IN the city) RCT included 245 community dwelling older adults (age ≥ 55y): control, exercise, and exercise plus dietary counseling (protein) group. Dietary intake was measured by a 3d dietary record at baseline and after 6 months intervention. In total 173 subjects were eligible for analysis. A two-way mixed ANOVA with time, group, and time*group interaction was performed. Post-hoc Bonferroni was performed with significance level at p<0.05.Results Mean age of the subjects was 72.1±6.3, with a BMI of 25.7±4.2 of which 68% were females. ANOVA revealed significant effect of time, group and time*group (p<0.001). Table 1 shows higher protein intake over time in the dietary counseling group than either control (p=0.038) or exercise (p=0.008) group. Additional analyses revealed no change in vegetable protein intake. The higher protein intake was fully accounted for by animal protein intake. In the dietary counseling group 72% of subjects increased protein intake above the minimum intake level.Conclusions This study shows digitally supported dietary counseling improves protein intake sufficiently in community dwelling older adults. Protein intake increase by counseling with m-health is a promising strategy for dieticians with the upcoming rising ageing population.Keywords: Aging, Sarcopenia, Functioning, Nutrition, Technology
