This study investigated access and use of information in the health-care of home-based elderly people (EPs) in Nakuru District, Kenya. The literature review revealed a gap with respect to information behaviour in health-care of EPs in a development context. The researcher used qualitative methods; with exploratory and descriptive research design because the focus of the study was on the littleknown and socially disadvantaged community of EPs in Nakuru District. Respondents were sampled by using the snowball technique. At the end of an interview session, each respondent was encouraged to nominate someone who either shared the same or had different experiences, views, socio-economic levels and gender. The researcher collected data through face-to-face interviews with EPs, informal care providers (ICPs) and formal health-care providers (FHCPs), in order to gain insight of information behaviour in health-care of EPs, by focusing on aspects of information needs; sources; use of information and factors that influence the respective groups of respondents to access and use health-care information health-care of EPs. The findings showed that the respective groups of respondents had similar as well as diversified needs for information for health-care. The groups used both formal and informal sources of information and channels of communication to access information for health-care, with FHCPs using authoritative sources more than the EPs and ICPs. Factors such as being a professional or a lay person, cost, ease of accessibility, availability of sources and channels of communication, time and trustworthiness of a source or channel of communication determined preference for use of information. The major contribution of the study is to the theory about information behaviour: some EPs and ICPs used CAM services without informing FHCPs, thereby revealing a form of concealed information use behaviour (CIUB). / Information Science / D.

Modeling the "thick description" of photographs began at the intersection of personal and institutional descriptions. Comparing institutional descriptions of particular photos that were also used in personal online conversations was the initial phase. Analyzing conversations that started with a photographic image from the collection of the Library of Congress (LC) or the collection of the Manchester Historic Association (MHA) provided insights into how cultural heritage institutions could enrich the description of photographs by using informal descriptions such as those applied by Facebook users. Taking photos of family members, friends, places, and interesting objects is something people do often in their daily lives. Some photographic images are stored, and some are shared with others in gatherings, occasions, and holidays. Face-to-face conversations about remembering some of the details of photographs and the event they record are themselves rarely recorded. Digital cameras make it easy to share personal photos in Web conversations and to duplicate old photos and share them on the Internet. The World Wide Web even makes it simple to insert images from cultural heritage institutions in order to enhance conversations. Images have been used as tokens within conversations along with the sharing of information and background knowledge about them. The recorded knowledge from conversations using photographic images on Social Media (SM) has resulted in a repository of rich descriptions of photographs that often include information of a type that does not result from standard archival practices. Closed group conversations on Facebook among members of a community of interest/practice often involve the use of photographs to start conversations, convey details, and initiate story-telling about objets, events, and people. Modeling of the conversational use of photographic images on SM developed from the exploratory analyses of the historical photographic images of the Manchester, NH group on Facebook. The model was influenced by the typical model of Representation by Agency from O'Connor in O'Connor, Kearns, and Anderson Doing Things with Information: Beyond Indexing and Abstracting, by considerations of how people make and use photographs, and by the notion of functionality from Patrick Wilson's Public Knowledge, Private Ignorance: Toward a Library and Information Policy. The model offers paths for thickening the descriptions of photographs in archives and for enriching the use of photographs on social media.
