With a growing ageing population and the advent of interactive TV (iTV), understanding how older people use iTV services is a timely and important task. Working towards this end, this paper reports on in situ conversations of, and observations with, almost 400 older people, with different levels of educational attainment and experience with ICTs, while talking about and using online video portals and similar interactive systems in Spain, Brazil and Denmark. The results show more similarities than differences in their reasons for adopting online video portals and patterns of use. All our participants used these portals for keeping or remaining in touch with people they trusted. The results also show that privacy online was a common concern to all the participants. Differences in the acceptance of e-government services and the type of content that drove most of their interactions were also found. Implications for designing more accessible and meaningful iTV services are discussed. [ABSTRACT FROM AUTHOR]

This paper aims to examine whether cultural differences have an impact on Behavioral Information Security. For this purpose, the authors used ANOVA to investigate if individuals act securely through a survey among three dimensions defined by Hofstede, which are Individualism versus Collectivism (IDV), Uncertainty Avoidance Index (UAI) and Indulgence versus Restraint (IND). It was found that individuals with collectivism, high UAI and restraint cultural features act more securely than those without these cultural features. The results also revealed that the main effects of IDV and IND, the interaction of IDV and UAI, IDV, UAI and IND, have a significant impact on behavioral information security. [ABSTRACT FROM AUTHOR]
