In this paper, we examine young people's data literacy in terms of their awareness of data and the rhetoric that surrounds it, as well as their knowledge of data flows. This is the first phase of the Exploring Data Worlds at the Public Library research study research study, a two-year research study that explores the ways that libraries can address data literacy programming by helping teens understand, create and manage the digital traces of their data in meaningful, efficacious, and ethical ways. In this first phase of the study we explored the question What do young people understand about data within the context of their everyday lives and in relation to personal data management. We present here the findings from a series of semi-structured interviews with young people, ages 11 to 18, that examined teens' perceptions and general knowledge of data in their lives. Results suggest that the teens in this study had varying interpretations of the nature of data and a broad understanding of the lifecycle of data, but most found it difficult to connect with data at a concrete and personal level, with the notion of a personal data dossier either non-existent or abstract.

Purpose – Information encountering is the serendipitous acquisition of information that requires low or no involvement and expectation of users. The purpose of this paper is to model the explicit process and the implicit factors of online information encountering, i.e. how and why it occurs. Design/methodology/approach – The critical incident technique was adopted to collect qualitative data from 16 interview participants. They contributed 27 true incidents of online information encountering which were used to identify the key phases of the encountering process. They also commented on the factors that they thought had an influence on the chance of the occurrence of encountering. Findings – The macro-process of information encountering is composed of three phases. First, browsing, searching, or social interaction provides the context for encountering; second, the encountering occurrence consists of three steps – noticing the stimuli, examining the content, and acquiring interesting or useful content; and third, the information encountered will be explored further, saved, used, or shared. The 14 influencing factors of information encountering obtained divide into three clusters. User-related factors include sensitivity, emotions, expertise, attitudes, intentionality, curiosity, activity diversity; information-related factors include type, relevance, quality, visibility, and sources; and environment-related factors include time limits and interface usability. Originality/value – This study engenders useful implications for designing information encountering experience. The changeable nature of some influencing factors suggests that encountering can be elicited through the purposive design of encountering support features or even encountering systems, and the macro-process depicts the natural occurring mechanisms of encountering for the design to follow.

For laypeople, searching online health information resources can be challenging due to topic complexity and the large number of online sources with differing quality. The goal of this article is to examine, among all the available online sources, which online sources laypeople select to address their health‐related information needs, and whether or how much the severity of a health condition influences their selection. Twenty‐four participants were recruited individually, and each was asked (using a retrieval system called HIS) to search for information regarding a severe health condition and a mild health condition, respectively. The selected online health information sources were automatically captured by the HIS system and classified at both the website and webpage levels. Participants' selection behavior patterns were then plotted across the whole information‐seeking process. Our results demonstrate that laypeople's source selection fluctuates during the health information‐seeking process, and also varies by the severity of health conditions. This study reveals laypeople's real usage of different types of online health information sources, and engenders implications to the design of search engines, as well as the development of health literacy programs.

Objective: To explore UK public perceptions of children's sugar consumption, Public Health England's Change4Life Sugar Smart app and the Soft Drinks Industry Levy, using solicited and unsolicited digital data. Methods: Data from three digital spaces were used as follows: (1) an online questionnaire advertised on parenting forums; (2) posts to UK online parenting forums; and (3) English language Tweets from Twitter. Quantitative data were analysed using descriptive statistics and qualitative data using content and inductive thematic analysis.Results: Data were (study 1) 184 questionnaire participants; (study 2) 412 forum posts; and (study 3) 618 Tweets. In study 1, 94.0% (n = 173) agreed that children in the UK consumed too much sugar and this had a negative health effect (98.4%, n = 181). Environments (n = 135, 73.4%), media/advertising (n = 112, 60.9%) and parents (n = 107, 58.2%) were all reported as barriers to changing children's sugar intake. In study 2, more posts were negative towards the Soft Drinks Industry Levy (n = 189, 45.9%) than positive (n = 145, 35.2%), and themes about the inability of the Levy to affect sugar consumption in children and childhood obesity emerged. Other themes related to distrust of the government, food industry and retailers. In study 3, the Sugar Smart app was viewed positively (n = 474, 76.7%) with its function associated solely with identification of sugar content. Conclusions: Participants accepted the necessity of sugar reduction in children, but recognised the complexity of behaviour change. Public health activities were not always perceived as effective strategies for health promotion. There was some distrust in government, public health officials and the food industry. A less simplistic approach to sugar reduction and more credible sources of information may, therefore, be welcomed by the public.
