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.

Sharing platforms gained importance in recent years. Little is known about whether and why novel means to digitally share meals are incorporated into people’s everyday portfolios of everyday food provisioning. The objective of this paper is accordingly to explore why digitally mediated meal sharing is incorporated (or not) into an array of everyday food provisioning practices. We use observations of and interviews with users of the Dutch platform Thuisgekookt, on which home cooks offer meals to be picked up by neighbors. Three teleoaffective episodes - anticipating, actualizing and assessing - assist in explaining why meal sharing recruits practitioners (or not).

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate.

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.

Met de opkomst van massacommunicatie in de twintigste eeuw en de toenemende reikwijdte van commerciële reclameboodschappen, is onze samenleving jarenlang collectief opgevoed met ideeën over consumptie van goederen en diensten. Oorspronkelijk ging commerciële communicatie vooral over het garanderen van de kwaliteit van merkproducten.

This paper proposes and showcases a methodology to develop an observational behavior assessment instrument to assess psychological competencies of police officers. We outline a step-by-step methodology for police organizations to measure and evaluate behavior in a meaningful way to assess these competencies. We illustrate the proposed methodology with a practical example. We posit that direct behavioral observation can be key in measuring the expression of psychological competence in practice, and that psychological competence in practice is what police organizations should care about. We hope this paper offers police organizations a methodology to perform scientifically informed observational behavior assessment of their police officers’ psychological competencies and inspires additional research efforts into this important area.

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.

This paper presents the results of a business – university collaborative research project on defining lower management competencies in the year 2025. The purpose of the research was to help a large local airport to define and understand what competencies lower management will need in order to function effectively in the renewed organization portrayed in an internal strategic document called “Chief Plan 2025”. At the same time the research was needed as input for developing new business curricula. Field research was done by a team of five researchers using focus groups and interviews with 43 employees from 15 different business units. Three general types of critical competencies emerged from the data; professional, interpersonal and personal. Management implications are that the airport will need to adapt its HRM policies. New business curricula will need to help graduates to work in roles, rather than functions. Limitations are linked to the generalizability of the results and the fact that the research was organization-centric, meaning broad societal changes that might affect individuals’ attitudes and in turn their attitude towards work were not considered.

Change is endemic in modern society, and the educational systems that operate in it. In Higher Education societal trends such as globalization and economic rationalism are impacting on teachers. Changes in the student population, new educational methods derived from shifting perspectives on the role of knowledge and re-structuring of the organizations within which teachers work have also led to transformation of the professional context. At European level policy initiatives such as the Bologna Declaration (1999) have necessitated an overhaul of educational provision. This research project attempts to focus on these wideranging changes through the lens of teacher autonomy in order to establish what is changing in the working lives of teachers in a Dutch university, how they are responding to these changes and how they can be helped to respond to change effectively and discriminatingly. This is an insider research project, using case study and semi-structured interviewing to yield data that is subjected to thematic linguistic analysis. It was piloted in 2006, and interviewing was resumed in February 2007. Findings indicate the contested nature of teacher autonomy, and suggest that professional autonomy can impede as well as facilitate teachers in processes of engaging with change. The team - operating as a community of practice - is identified as the location where change agency can operate most effectively. Distributed leadership - specifically perceived in the activities of team leaders and teacher change agents - is seen as crucial to processes of embedding change in educational practice.
