This paper introduces the Internet-of-Things (IoT) and describes its evolution from a concept proposed by Kevin Ashton in 1999 through its public emergence in 2005 in a United Nations ITU report entitled “The Internet of Things”, to the present day where IoT devices are available as off-the-shelf products from major manufacturers. Using a systematic study of public literature, the paper presents a five-phase categorisation of the development of the Internet-of-Things from its beginnings to the present day. Four mini case studies are included to illustrate some of the issues involved. Finally, the paper discusses some of the big issues facing future developers and marketers of Internet-of-Things based products ranging from artificial intelligence (AI) through to customer privacy and acceptance finishing with an optimistic assessment of the future of the Internet-of-Things.
OBJECTIVES: This systematic and meta-analytic review aimed to quantify the association of psychosocial correlates with oral hygiene behaviour among 9- to 19-year olds. METHODS: A systematic search up to August 2015 was carried out using the following databases: PubMed, PsycInfo, Embase, CINAHL and Web of Science. If necessary, authors of studies were contacted to obtain unpublished statistical information. A study was eligible for inclusion when it evaluated the association between the psychosocial correlates and oral hygiene behaviour varying from self-reports to clinical measurements, including plaque and bleeding scores. A modified New Castle Ottawa Scale was applied to examine the quality of the included studies. RESULTS: Twenty-seven data sets (k) presented in 22 publications, addressing nine psychosocial correlates, were found to be eligible for the meta-analysis. For both tooth brushing and oral hygiene behaviour, random effect models revealed significant weighted average correlation (r+ ) for the psychosocial factors: 'intention', 'self-efficacy', 'attitude' (not significant for tooth brushing), 'social influence', 'coping planning' and 'action planning' (r+ ranging from 0.18 to 0.57). Little or no associations were found for 'locus of control', 'self-esteem' and 'sense of coherence' (r+ ranges from 0.01 to 0.08). CONCLUSIONS: The data at present indicates that 'self-efficacy', 'intention', 'social influences', 'coping planning' and 'action planning' are potential psychosocial determinants of oral health behaviour. Future studies should consider a range of psychological factors that have not been studied, but have shown to be important psychosocial determinants of health behaviours, such as 'self-determination', 'anticipated regret', 'action control' and 'self-identity'. Effectiveness of addressing these potential determinants to induce behaviour change should be further examined by intervention trials.
MULTIFILE
Het ontwikkelen van een goede multichannel strategie is één van de belangrijkste uitdagingen waar retailers vandaag de dag voor staan. Een toenemend aantal ‘traditionele’ retailers ziet het opzetten van een webshop als een belangrijke aanvulling op hun fysieke winkels en probeert te profiteren van de groeiende e-commerce markt. Om retailers te helpen bij de uitdagingen die het combineren van een webshop met fysieke winkels met zich mee brengen, hebben PwC en de Hogeschool van Amsterdam een verkennend onderzoek uitgevoerd. Het doel van het onderzoek is om in kaart te brengen hoe multichannel retailers hun bedrijf optimaliseren. In het bijzonder wordt gekeken naar de strategische en operationele uitdagingen waar multichannel retailers voor staan en de manieren waarop zij deze aanpakken. De resultaten zijn gebaseerd op interviews en een online enquête onder 41 multichannel retailers in Nederland.
