Het ontwerp van gezondheidsgamebeloningen voor preadolescenten

The design of health game rewards for preadolescents Videogames are a promising strategy for child health interventions, but their impact can vary depending on the game mechanics used. This study investigated achievement-based ‘rewards’ and their design among preadolescents (8-12 years) to assess their effect and explain how they work. In a 2 (game reward achievement system: social vs. personal) x 2 (game reward context: in-game vs. out-game) between-subjects design, 178 children were randomly assigned to one of four conditions. Findings indicated that a ‘personal’ achievement system (showing one’s own high scores) led to more attention and less frustration than a ‘social’ achievement system (showing also high scores of others) which, in turn, increased children’s motivation to make healthy food choices. Furthermore, ‘out’-game rewards (tangible stickers allocated outside the game environment) were liked more than ‘in’-game rewards (virtual stickers allocated in the game environment), leading to greater satisfaction and, in turn, a higher motivation to make healthy food choices.

De kloof overbruggen

Toen grote groepen vluchtelingen in ons land aanklopten, werd in tal van gemeenten naarstig gezocht naar verblijfsplaatsen. De inzet om vluchtelingen te herbergen stuitte op grote weerstand. Het meest flagrant was het verzet in Geldermalsen. Burgers kwamen in opstand tegen de gemeentelijke overheid. Trouw publiceerde op de voorpagina een iconische foto van dit volksoproer. Een vrouw met een van woede vertrokken gezicht, mond wijd open. Het was een variant op De Schreeuw van Munch, waarbij nu niet de angst maar vooral de woede in het oog sprong.

Analysing and visualising the trends in knowledge management

The purpose of this study was to analyse knowledge management research trends to understand the development of the field using a combination of scientometric, bibliometric, and visualisation techniques, subsequently developing a normative framework of knowledge management from the results.282 articles between the years 2010–2015 were retrieved, analysed, and visualised to produce the state of knowledge management during the selected timeframe. The results of this study provide a visualisation of the current research trends to understand the development of the knowledge management discipline. There are signals that the literature about knowledge management is progressing towards academic maturity. This study is one of the first studies to combine bibliometric and scientometric methods to assess productivity along with visualisation, and subsequently provide a knowledge management framework drawing from the results of these methods.

People Analytics

Hoofdstuk 10 in HRM Heden en Morgen. Dit hoofdstuk is geschreven vanuit de overtuiging dat een gemeenschappelijke taal en begrip van people analytics, evenals enkele basale wetenschappelijke principes waarop het gestoeld is, het jonge vakgebied in de praktijk naar een hoger niveau kunnen tillen. En daarmee de (toekomstige) HRM-professionals werkzaam op en rondom dit uitdagende thema in staat kunnen stellen (nog meer) impact te maken in hun organisatie. Het primaire doel van dit hoofdstuk is om de (toekomstige) professional die dit leest, aan het denken te zetten. Dit kan betekenen inspireren, verwarren, of duiden. Maar ook aanzetten tot het concreet aan de slag gaan met people analytics in de eigen organisatie, op de grens van wetenschap en praktijk, because that’s where the magic happens.

Evolutionary analysis of the carnitine- and choline acyltransferases suggests distinct evolution of CPT2 versus CPT1 and related variants

Carnitine/choline acyltransferases play diverse roles in energy metabolism and neuronal signalling. Our knowledge of their evolutionary relationships, important for functional understanding, is incomplete. Therefore, we aimed to determine the evolutionary relationships of these eukaryotic transferases. We performed extensivephylogenetic and intron position analyses. We found that mammalian intramitochondrial CPT2 is most closely related to cytosolic yeast carnitine transferases (Sc-YAT1 and 2), whereas the other members of the family are related to intraorganellar yeast Sc-CAT2. Therefore, the cytosolically active CPT1 more closely resembles intramitochondrial ancestors than CPT2. The choline acetyltransferase is closely related to carnitine acetyltransferase and shows lower evolutionary rates than long chain acyltransferases. In the CPT1 family several duplications occurred during animal radiation, leading to the isoforms CPT1A, CPT1B and CPT1C. In addition, we found five CPT1-like genes in Caenorhabditis elegans that strongly group to the CPT1 family. The long branch leading to mammalian brain isoform CPT1C suggests that either strong positive or relaxed evolution has taken place on this node. The presented evolutionary delineation of carnitine/choline acyltransferases adds to current knowledge on their functions and provides tangible leads for further experimental research.
