OBJECTIVES: To make practical recommendations for improving oral hygiene behavior (OHB) potential predictors based on the Theory of Planned Behavior (TPB) were assessed. Measurements of oral health knowledge (OHK) and the expected social effect for having healthy teeth were included.METHODS: 216 recruits in the Dutch Army ground forces completed a questionnaire about oral hygiene behavior, attitudes, social norms, perceived behavioral control (PBC), intention to perform optimal OHB, OHK, and expected social outcomes.RESULTS: The multivariate regression analysis revealed that attitude and PBC explained 37.2% of the variance in intention to perform optimal oral hygiene behavior, which is a substantial proportion. Furthermore, actual oral hygiene behavior was only predicted by attitude, explaining 7.1% of the variance.CONCLUSION: The present findings suggest that recruits' oral hygiene behavior may be improved by promoting a more positive attitude and especially by enhancing perceived behavior control.

The massive die-off of the sea urchin Diadema antillarum in 1983–1984 is one the main reasons for low coral recruitment and little coral recovery in the Caribbean. As the natural recovery of D. antillarum is slow to non-existent, multiple restoration studies have been attempted. There are currently three different approaches to obtain individuals for restocking: the translocation of wild-collected juveniles or adults, lab-reared juveniles cultured from wild-collected settlers, or lab-reared juveniles cultured from gametes. All three methods are costly and can only be applied on a relatively small scale. We here propose a fourth, new, approach, which we term assisted natural recovery (ANR) of D. antillarum populations. ANR, a concept already applied in terrestrial restoration to restore forests and grasslands, can accelerate succession by removing barriers to natural recovery. In this study, performed on the Dutch Caribbean island of Saba, suitable settlement substrate was provided in the form of bio ball streamers that were attached to the reef shortly before the settlement season. At the end of the experiment, reefs with streamers had significantly higher D. antillarum recruit densities than control reefs without additional settlement substrate, indicating that the lack of settlement substrate is an important factor constraining natural recovery. However, D. antillarum recruit abundance was low compared to the measured settlement rates, possibly due to low post-settlement survival. The size distribution of recruits showed that recruits almost never became larger than 20 mm, which is likely due to predation. We conclude that, next to low settlement availability, low post-settlement survival and high predation on recruits also constrain the natural recovery of D. antillarum populations on Saba. To improve the survival of settlers till adults, we propose to 1) reduce predation on settlers by using bio balls or other substrates that can provide shelter to larger individuals and 2) optimize the reef habitat by removing macroalgae, either manually or by facilitating other herbivores. To improve the survival of recruits, we suggest to 1) choose sites with a known lower predation density or 2) protect recruits with a corral around the reef underneath the streamers. The combination of these measures could improve prospects for ANR, and we expect this new approach can contribute to the recovery of D. antillarum populations in the future.

Background: This paper presents the researchers’ experiences with recruiting people living with dementia for a field study aimed to test or develop non-pharmacological interventions. Performing this kind of research is necessary to be able to provide appropriate and effective interventions for people with dementia. Research aim/questions: The aim is to find out the pros and cons of recruiting PwD for field studies comprising technological innovations. Methods: This short paper is based on the experiences of researchers during their studies, combined with a rapid literature search. Results: Incorporating technological innovations as a non-pharmacological intervention poses a challenge to recruitment success. Several influencing factors influence the success of the recruitment process. For example, personal contact or recruitment via welfare and care organizations can be helpful. Conclusion: Collaboration and different strategies can be helpful for the recruitment process.

Doelstellingen De mate van betrokkenheid van jonge gebruikers bij wervingsadvertenties voor geldezels op Instagram onderzoeken. Methoden Drie advertenties die de belangrijkste mechanismen voor betrokkenheid bij cybercriminaliteit weerspiegelen en gericht waren op Nederlandse gebruikersclusters werden op twee Instagram-plaatsingen geplaatst. Door middel van dit quasi-experimentele 3 × 2 factorial design konden we het bereik en de weergaven van de advertenties, de doorklikratio's, het geslacht van de deelnemers en de temporele verdelingen van de gebruikersbetrokkenheid analyseren. Resultaten De analyse toont aan dat tot 3% van de jonge gebruikers zich bezighield met de advertenties, vooral met advertenties die een luxe levensstijl promoten en neutralisatietechnieken gebruiken. Mannen waren vaker betrokken en 's nachts werd er meer geklikt. Conclusies Sommige jonge Instagram-gebruikers lijken geneigd om geld te verdienen via hun bankpas en lopen het risico om online betrokken te raken bij cybercriminaliteit. We moedigen toekomstig onderzoek aan om het gebruik van sociale media in criminologische studies verder te onderzoeken. ENGLISH Objectives Examine the level of engagement of young users with money mule recruitment ads on Instagram. Methods Three ads reflecting key cybercrime involvement mechanisms and targeting Dutch user clusters were run on two Instagram placements. By means of this quasi-experimental 3 × 2 factorial design, we were able to analyze the reach and views of the ads, click-through rates, gender of the participants, and temporal distributions of user engagement. Results Mimicking actual recruitment environments, analysis shows that up to 3% of young users engaged with the ads, especially those promoting a luxury lifestyle and using neutralization techniques. Men were more likely to engage, and click-through rates were higher at night. Conclusions Some young Instagram users seem prone to making money through their bank cards and risk becoming involved in cybercrime online. We encourage future research to explore further the use of social media in criminological studies.

In a rapidly developing labor market, in which some parts of jobs disappear and new parts appear due to technological developments, companies are struggling with defining future-proof job qualifications and describing job profiles that fit the organization’s needs. This is even more applicable to smaller companies with new types of work because they often grow rapidly and cannot hire graduates from existing study programs. In this research project, we undertook in-depth, qualitative research into the five roles of a new profession: social media architect. It has become clear which 21st century skills and motivations are important per role and, above all, how they differ in subcategory and are interpreted by a full-service team in their working methods, in a labor market context, and in the talents of the professional themselves. In a workshop, these “skills” were supplemented through a design-based approach and visualized per team role in flexibly applicable recruitment cards. This research project serves as an example of how to co-create innovative job profiles for the changing labor market.

Objective: Many physical activity interventions do not reach those people who would benefit the most from them. The Groningen Active Living Model (GALM) was successful in recruiting sedentary and underactive older adults. Method: In the fall of 2000 older adults in three municipalities in the Netherlands received written information, were visited at home and, if eligible according to the GALM recruitment criteria, filled in the Stages of Change questionnaire and the Voorrips physical activity questionnaire. Results: By using the strategy we succeeded in including 12.3% of the older adults (315 of the 2551 qualifying participants), 79.4% of whom could be indeed regarded as sedentary or underactive. These results can be considered in line with results described in the literature. The cost of successfully recruiting an older adult was estimated at $84. Conclusions: The GALM recruitment strategy is a potentially useful and effective method for reaching community-dwelling sedentary and underactive older adults. © 2008 Elsevier Inc.

Fish assemblages of different types of artificial reefs can differ greatly in abundance, biomass and composition, with some reef types harboring over five times more herbivores than others. It is assumed that higher herbivorous fish abundance results in a higher grazing intensity, affecting the benthic community by means of enhanced coral recruitment, survival and growth. Territorial fish species might affect this process by chasing away other fish, especially herbivores. In this study we compared the fish assemblage, territorial behavior and grazing intensity by fish on two artificial reef types: reef balls and layered cakes, differing greatly in their fish assemblage during early colonization. In addition, the effect of artificial reef type on benthic development and coral recruitment, survival and growth, was investigated. Although layered cakes initially harbored higher herbivorous fish biomass, this effect was lost during consecutive monitoring events. This seems to be the result of the higher territorial fish abundance around the layered cakes where almost four times more chasing behavior was recorded compared to the reef balls. This resulted in a more than five times lower fish grazing intensity compared to the reef-ball plots. Although macroalgae were effectively controlled at both reefs, the grazing intensity did not differ enough to cause large enough structural changes in benthic cover for higher coral recruitment, survival or growth. The high turf algae cover, combined with increasing crustose coralline algae and sponge cover likely explained reduced coral development. We recommend further research on how to achieve higher grazing rates for improved coral development on artificial reefs, for example by facilitating invertebrate herbivores.

The Confederation of European Probation detects a clear need for a central record of training and qualification requirements, standards or curricula for probation and community supervision practitioners in EU Member States. Hogeschool Utrecht (UAS) has been commissioned to conduct a survey to collect an overview of qualification requirements and training of probation workers in order to set up a network to share knowledge, competencies and expertise among members’ states. The research question is: What kind of formation precedes the start of a career of a probation worker in the various EU Member states and how does it develop throughout his or her career? In order to answer this question, an online survey with closed and open questions has been send out among CEP members that provide or are responsible for probation services. Twenty of them filled out the questionnaire covering 18 different countries.

This ‘cohort profile’ aims to provide a description of the study design, methodology, and baseline characteristics of the participants in the Corona Behavioral Unit cohort. This cohort was established in response to the COVID-19 pandemic by the Dutch National Institute for Public Health and the Environment (RIVM) and the regional public health services. The aim was to investigate adherence of and support for COVID-19 prevention measures, psychosocial determinants of COVID-19 behaviors, well-being, COVID-19 vaccination, and media use. The cohort also examined specific motivations and beliefs, such as for vaccination, which were collected through either closed-ended items or open text responses. In April 2020, 89,943 participants aged 16 years and older were recruited from existing nation-wide panels. Between May 2020 and September 2022, 99,676 additional participants were recruited through online social media platforms and mailing lists of higher education organizations. Participants who consented were initially invited every three weeks (5 rounds), then every six weeks (13 rounds), and since the summer of 2022 every 12 weeks (3 rounds). To date, 66% of participants were female, 30% were 39 years and younger, and 54% completed two or more questionnaires, with an average of 9.2 (SD = 5.7) questionnaires. The Corona Behavioral Unit COVID-19 cohort has published detailed insights into longitudinal patterns of COVID-19 related behaviors, support of COVID-19 preventive measures, as well as peoples’ mental wellbeing in relation to the stringency of these measures. The results have informed COVID-19 policy making and pandemic communication in the Netherlands throughout the COVID-19 pandemic. The cohort data will continuously be used to examine COVID-19 related outcomes for scientific analyses, as well as to inform future pandemic preparedness plans.
