    Abstract
    Evaluating the quality of online health information (OHI) is a major challenge facing consumers. We designed PageGraph, an interface that displays quality indicators and associated values for a webpage, based on credibility evaluation models, the nudge theory, and existing empirical research concerning professionals' and consumers' evaluation of OHI quality. A qualitative evaluation of the interface with 16 participants revealed that PageGraph rendered the information and presentation nudges as intended. It provided the participants with easier access to quality indicators, encouraged fresh angles to assess information credibility, provided an evaluation framework, and encouraged validation of initial judgments. We then conducted a quantitative evaluation of the interface involving 60 participants using a between-subject experimental design. The control group used a regular web browser and evaluated the credibility of 12 preselected webpages, whereas the experimental group evaluated the same webpages with the assistance of PageGraph. PageGraph did not significantly influence participants' evaluation results. The results may be attributed to the insufficiency of the saliency and structure of the nudges implemented and the webpage stimuli's lack of sensitivity to the intervention. Future directions for applying nudges to support OHI evaluation were discussed.

    Abstract
    In a digital library, book search is one of the most important information services. However, with the rapid development of network technologies such as cloud computing, the server-side of a digital library is becoming more and more untrusted; thus, how to prevent the disclosure of users' book query privacy is causing people's increasingly extensive concern. In this article, we propose to construct a group of plausible fake queries for each user book query to cover up the sensitive subjects behind users' queries. First, we propose a basic framework for the privacy protection in book search, which requires no change to the book search algorithm running on the server-side, and no compromise to the accuracy of book search. Second, we present a privacy protection model for book search to formulate the constraints that ideal fake queries should satisfy, that is, (i) the feature similarity, which measures the confusion effect of fake queries on users' queries, and (ii) the privacy exposure, which measures the cover-up effect of fake queries on users' sensitive subjects. Third, we discuss the algorithm implementation for the privacy model. Finally, the effectiveness of our approach is demonstrated by theoretical analysis and experimental evaluation.

    Abstract
    Purpose This study aims to develop an in-depth understanding of the underlying dynamics of an emergent shared information practice within a Facebook group, and the resources the group develops to sustain this practice. Design/methodology/approach In-depth semi-structured interviews were carried out with twenty members from the group. The findings are based on comparative analysis combined with narrative analysis and were interpreted using theories of situated learning and Community of Practice. Findings The study shows that although members of this multicultural mothers group endorsed different, sometimes opposing parenting practices, the group had to find common ground when sharing information. Managing these challenges was key to maintaining the group as an open information resource for all members. The group produced a shared repertoire of resources to maintain its activities, including norms, rules, shared understandings, and various monitoring activities. The shared online practice developed by the community is conceptualised in this article as an information practice requiring shared, community-specific understandings of what, when, and how information can or should be sought or shared in ways that are valued in this specific community. The findings show that this shared information practice is not static but continually evolves as members negotiate what is, or not, important for the group. Originality/value The research provides novel insights into the underlying dynamics of the emergence, management, and sustainability of a shared information practice within a contemporary mothers group on Facebook.

    Abstract
    In 2015, the PCC Task Group on URIs in MARC was tasked to identify and address linked data identifiers deployment in the current MARC format. By way of a pilot test, a survey, MARC Discussion papers, Proposals, etc., the Task Group initiated and introduced changes to MARC encoding. The Task Group succeeded in laying the ground work for preparing library data transition from MARC data to a linked data, RDF environment.

    Abstract
    Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here we use change-point analysis to estimate the timing of changes in the rate of hominin brain evolution. We find that hominin brains experienced positive rate changes at 2.1 and 1.5 million years ago, coincident with the early evolution of Homo and technological innovations evident in the archeological record. But we also find that human brain size reduction was surprisingly recent, occurring in the last 3,000 years. Our dating does not support hypotheses concerning brain size reduction as a by-product of body size reduction, a result of a shift to an agricultural diet, or a consequence of self-domestication. We suggest our analysis supports the hypothesis that the recent decrease in brain size may instead result from the externalization of knowledge and advantages of group-level decision-making due in part to the advent of social systems of distributed cognition and the storage and sharing of information. Humans live in social groups in which multiple brains contribute to the emergence of collective intelligence. Although difficult to study in the deep history of Homo, the impacts of group size, social organization, collective intelligence and other potential selective forces on brain evolution can be elucidated using ants as models. The remarkable ecological diversity of ants and their species richness encompasses forms convergent in aspects of human sociality, including large group size, agrarian life histories, division of labor, and collective cognition. Ants provide a wide range of social systems to generate and test hypotheses concerning brain size enlargement or reduction and aid in interpreting patterns of brain evolution identified in humans. Although humans and ants represent very different routes in social and cognitive evolution, the insights ants offer can broadly inform us of the selective forces that influence brain size.

    Abstract
    Rarely does any empirical investigation show how administrators routinely control information in online communities and alleviate misinformation, hate speech, and information overload supported by profit-driven algorithms. Thematic analysis of in-depth phone interviews with members and administrators of a "Vaginal Birth After Cesarean" (VBAC) group with over 500 new mothers on Facebook shows that the administrators make 19 choices for recurring, authoritative but evolving 19 information-related activities when (a) forming the VBAC group over Facebook for local new mothers, (b) actively recruiting women who had a VBAC or have related competencies, (c) removing doctors and solicitors from the group, (d) setting up and revising guidelines for interactions in the group, (e) maintaining the focus of the group, (f) initiating distinct threads of conversations on the group, (g) tagging experts during conversations in the group, and (h) correcting misinformation. Thirty-eight information practices of the administrators indicate their nine gatekeeping roles, seven of these roles help administrators alleviate misinformation, hate speech, and information overload. Findings also show that the management of members and their interactions is a prerequisite to controlling information in online communities. Prescriptions to social networking companies and guidelines for administrators of online communities are discussed at the end.

    Abstract
    Purpose The purpose of this paper is to lay a theoretical foundation for identifying operational information units for library and information professional activities in the context of scholarly communication. Design/methodology/approach The study adopts a deduction-verification approach to formulate a typology of units for scholarly information. It first deduces possible units from an existing conceptualization of information, which defines information as the combined product of data and meaning, and then tests the usefulness of these units via two empirical investigations, one with a group of scholarly papers and the other with a sample of scholarly information users. Findings The results show that, on defining an information unit as a piece of information that is complete in both data and meaning, to such an extent that it remains meaningful to its target audience when retrieved and displayed independently in a database, it is then possible to formulate a hierarchical typology of units for scholarly information. The typology proposed in this study consists of three levels, which in turn, consists of 1, 5 and 44 units, respectively. Research limitations/implications The result of this study has theoretical implications on both the philosophical and conceptual levels: on the philosophical level, it hinges on, and reinforces the objective view of information; on the conceptual level, it challenges the conceptualization of work by IFLA's Functional Requirements for Bibliographic Records and Library Reference Model but endorses that by Library of Congress's BIBFRAME 2.0 model. Practical implications It calls for reconsideration of existing operational units in a variety of library and information activities. Originality/value The study strengthens the conceptual foundation of operational information units and brings to light the primacy of "one work" as an information unit and the possibility for it to be supplemented by smaller units.

    Abstract
    In 2015, the PCC Task Group on URIs in MARC was tasked to identify and address linked data identifiers deployment in the current MARC format. By way of a pilot test, a survey, MARC Discussion papers, Proposals, etc., the Task Group initiated and introduced changes to MARC encoding. The Task Group succeeded in laying the ground work for preparing library data transition from MARC data to a linked data, RDF environment.

    Abstract
    The popularity of location-based features in social networks has been increasing over the past few years. Location information gathered from social networks can threaten users' information privacy through granular tracking and exposure of their preferences, behaviors, and identity. In this 6-week study (N = 35), we investigate the effect of "audience-group"-based interventions on Facebook check-in behavior of participants. These "audience-group"-based nudges help close the gap between the users' perceived audiences and those that are permitted to view their check-ins. The nudges remind users that their real-time location information may be visible to a larger group of friends than they expect. Based on both quantitative and qualitative data analyses, we report that reminding users of the unexpected audiences that have access to their location check-ins could be a promising way to help users manage their privacy in online location sharing. These findings motivate several recommendations for app designers as well as information privacy researchers to better design and evaluate location sharing in online social networks.

    Abstract
    Information and communication technology for development (ICT4D) research sporadically leverages information science scholarship. Our qualitative study employs the "information grounds" (IG) lens to investigate the consequences of information exchanges by pregnant women on Facebook, who are vulnerable in the doctor-centric birth culture in rural America. The thematic analysis of in-depth interviews with members and administrators of the Vaginal Birth After Cesarean (VBAC) group shows that positive consequences outweigh negative consequences of information exchanges and lead to the following progression of outcomes: (a) VBAC group as an information ground, (b) social capital (e.g., cognitive, structural, and relational capital) built on the information ground, (c) seven emergent properties of the information ground, and (d) value co-created (e.g., local, affordable, timely, enduring, and reliable support) by VBAC group members. The IG lens reveals the following roles of Facebook, an ICT, in development: (a) a linker that lets people with similar needs and interests convene and shapes their interactions, (b) a prerequisite to building an online, "third place" for social interactions, and (c) an apparatus for ubiquitously seeking, searching, sharing, and storing information in multiple formats and controlling its flow on the VBAC group. This paper fills in six gaps in the ICT4D research.

    Abstract
    Although there have been several studies of people's information behaviors during the COVID-19 epidemic, the information practices of a specific group of people-those with depression-have been neglected. This study reports on qualitative interviews with 24 participants to explore the information practices of people living with depression during the pandemic lockdown. We use the theory of information worlds and the concept of transition to understand the phases of chaos, expansion, and contraction that the information worlds of this group present during the lockdown, and examine the interrelationship between the information worlds and the individual's transition experiences during specific periods. Our results show that, first, emotion, body, and embodiment play key roles in the individual's information worlds, while individuals' information practices are regulated by the economic environment, group norms, and other social circumstances. Second, government-level information, the volunteer community, social media, and nonhuman objects further impact participants' information practices. We suggest that health management strategies need to have different priorities at different stages of the transition, and attention should be paid to the provision of emotional information support systems during the pandemic lockdown.

    Abstract
    Information grounds emerge as people share information with others in a common place. Many studies have investigated the emergence of information grounds in public places. This study pays attention to the emergence, peak, and abeyance of an online information ground. It investigates a Facebook group used by youth for sharing information when misinformation spread wildly during the 2011 violence in Ambon, Indonesia. The findings demonstrate change and continuity in an online information ground; it became an information hub when reaching a peak cycle, and an information repository when entering into abeyance. Despite this period of nonactivity, the friendships and collective memories resulting from information ground interactions last over time and can be used for reactivating the online information ground when new needs emerge. Illuminating the lifecycles of an online information ground, the findings have potential to explain the dynamic of users' interactions with others and with information in quotidian spaces.

    Abstract
    Although collective trolling is an integral part of online communities, it has received little scholarly attention. Research on collective trolling, which involves an organized group trolling effort, is in its infancy perhaps because early works on online trolling depicted it as the deviant behavior of individuals who acted in isolation and under hidden identity. Thus, it is still unclear what collective trolling is and how it evolves. To address this gap, we collected 12,840 posts and comments pertinent to a brief, controversial, and very visible collective trolling event. The event, which surrounded Chinese rapper PG One on the Chinese microblogging platform Sina Weibo , received 40 million reads in 1 day and a lot of media attention. Based on a thematic content analysis of 480 posts, we describe the collective trolling lifecycle through five distinct stages defined by posting frequency and content of posts. We also explain the transformation of participants' roles, tactics, motives, behavioral tone, and the variations in their thematic content, stakeholder group affiliation, and roles over time. The major contributions of the study are the characterization of collective trolling, and the addition of a lifecycle model to the understanding of trolling as sociotechnical, context-dependent, and multidimensional phenomenon.

    There is currently a paucity of evidence-based strategies that have been shown to increase citations of peer-reviewed articles following their publication. We conducted a 12-month randomized controlled trial to examine whether the promotion of article links in an online cross-publisher distribution platform (TrendMD) affects citations. In all, 3,200 articles published in 64 peer-reviewed journals across eight subject areas were block randomized at the subject level to either the TrendMD group (n = 1,600) or the control group (n = 1,600) of the study. Our primary outcome compares the mean citations of articles randomized to TrendMD versus control after 12 months. Articles randomized to TrendMD showed a 50% increase in mean citations relative to control at 12 months. The difference in mean citations at 12 months for articles randomized to TrendMD versus control was 5.06, 95% confidence interval [2.87, 7.25], was statistically significant (p?<?.001) and found in three of eight subject areas. At 6 months following publication, articles randomized to TrendMD showed a smaller, yet statistically significant (p = .005), 21% increase in mean citations, relative to control. To our knowledge, this is the first randomized controlled trial to demonstrate how an intervention can be used to increase citations of peer-reviewed articles after they have been published.
