1Greyson, D.L. ; Johnson, J.L.: ¬The role of information in health behavior : a scoping study and discussion of major public health models.
In: Journal of the Association for Information Science and Technology. 67(2016) no.12, S.2831-2841.
Abstract: Information interventions that influence health behavior are a major element of the public health toolkit and an area of potential interest and investigation for library and information science (LIS) researchers. To explore the use of information as a concept within dominant public health behavior models and the manner in which information practices are handled therein, we undertook a scoping study. We scoped the use of "information" within core English-language health behavior textbooks and examined dominant models of health behavior for information practices. Index terms within these texts indicated a lack of common language around information-related concepts. Nine models/theories were discussed in a majority of the texts. These were grouped by model type and examined for information-related concepts/constructs. Information was framed as a "thing" or resource, and information practices were commonly included or implied. However, lack of specificity regarding the definition of information, how it differs from knowledge, and how context affects information practices make the exact role of information within health behavior models unclear. Although health information interventions may be grounded in behavioral theory, a limited understanding of the ways information works within people's lives hinders our ability to effectively use information to improve health. By the same token, information scientists should explore public health's interventionist approach.

2Godfrey, B. ; Johnson, J.: ¬The geospatial metadata manager's toolbox : three techniques for maintaining records.
In: Code4Lib journal. Issue 29(2015), [http://journal.code4lib.org/issues/issues/issue29].
Abstract: Managing geospatial metadata records requires a range of techniques. At the University of Idaho Library, we have tens of thousands of records which need to be maintained as well as the addition of new records which need to be normalized and added to the collections. We show a graphical user interface (GUI) tool that was developed to make simple modifications, a simple XSLT that operates on complex metadata, and a Python script with enables parallel processing to make maintenance tasks more efficient. Throughout, we compare these techniques and discuss when they may be useful.

3Johnson, J.D.: Controlling the flood : when more of a dose is less.
In: Journal of documentation. 70(2014) no.3, S.330-345.
Abstract: Purpose - The purpose of this paper is to explore the flood of information that is inundating us. This flood makes it increasingly difficult to make sense of the world and arrive at the correct interpretation of events. Design/methodology/approach - Classic narrative literature review applying the dosage metaphor to the growing problem of information overload. Findings - The seven elements of dosage - amount, frequency, sequencing, delivery systems, contraindications, interactions, and dysfunctions - are used to discuss four major coping mechanisms - escape, attention, delegation, and creative destruction - for dealing with the flood. Each of the coping mechanisms has different entailments for the dosage elements. Originality/value - This essay develops a guiding principle for thinking about how we should cope with this central problem of the information age: suggesting a minimalist approach that offers the hope of clarity in acting in an age that increasingly overwhelms us.

4Johnson, J.D.: ¬An impressionistic mapping of information behavior with special attention to contexts, rationality, and ignorance.
In: Information processing and management. 45(2009) no.5, S.593-604.
Abstract: Recent years have seen an explosion of interest in human information behavior in part attributable to the rapid development of the Internet and associated information technologies. Concomitantly there has been substantial growth in theoretic frames, research, and substantive models. However, these approaches have often been fragmentary, dependent on the goals of disparate disciplines that are interested in differing aspects of information behavior. They often have been rooted in the most rational of contexts, libraries, where individuals come with a defined problem, or information technology systems, that have their own inherent logic. Attempts to extend this work to everyday life contexts often run into disquieting findings related to the benefits of ignorance and the seeming irrationality of human information behavior. A broader view of our social world leads us to richer policy implications for our work. We live in exciting times, in an increasingly flattened world, where the ability for people to assimilate information they find into coherent personal strategies is perhaps the critical modern survival skill.

5Johnson, J.D.E. ; Case, D.O. ; Andrews, J. ; Allard, S.L. ; Johnson, N.E.: Fields and pathways : contrasting or complementary views of information seeking.
In: Information processing and management. 42(2006) no.2, S.583-592.
Abstract: This research contrasts two different conceptions, fields and pathways, of individual information behavior in context. These different approaches imply different relationships between actors and their information environments and, thus, encapsulate different views of the relationship between individual actions and contexts. We discuss these different theoretical views, then empirically compare and contrast them. The operationalization of these conceptions is based on different analytic treatments of the same raw data: a battery of three questions based on respondent's unaided recall of the sources they would consult for information on inherited cancers, a particularly rich information seeking problem. These operationalizations are then analyzed in a nomological network of related concepts drawn from an omnibus survey of 882 adults. The results indicated four clusters for fields and 16 different pathways, indicating increased fragmentation of information environments, with different underlying logics and active ingredients, although the use of the Internet appears to be an emerging common theme. The analysis of the nomological network suggests that both approaches may have applications for particular problems. In the implications, we compare and contrast these approaches, discussing their significance for future methodological, analytical, and theoretical developments.

7Johnson, J.D.: On contexts of information seeking.
In: Information processing and management. 39(2003) no.5, S.735-760.
Abstract: While surprisingly little has been written about context at a meaningful level, context is central to most theoretical approaches to information seeking. In this essay I explore in more detail three senses of context. First, I look at context as equivalent to the situation in which a process is immersed. Second, I discuss contingency approaches that detail active ingredients of the situation that have specific, predictable effects. Third, I examine major frameworks for meaning systems. Then, I discuss how a deeper appreciation of context can enhance our understanding of the process of information seeking by examining two vastly different contexts in which it occurs: organizational and cancer-related, an exemplar of everyday life information seeking. This essay concludes with a discussion of the value that can be added to information seeking research and theory as a result of a deeper appreciation of context, particularly in terms of our current multi-contextual environment and individuals taking an active role in contextualizing.

8Johnson, J.L. ; Marmion, D.: Editing OPAC informational screens using a word processor and Windows.
In: Library software review. 13(1994) no.1, S.18-28.
Abstract: Describes the work carried out at Oklahoma State University to develop a means of editing and customizing the information screens provided with the NOTIS Library Management System, employing the WordPerfect word processing package and the Windows operating system. The capture capability of Windows was used to copy blocks of text screens from the NOTIS Library Management System into WordPerfect, where they could be easily edited and spell checked. Once each screen was ready, it was again captured using Windows and loaded into the NOTIS system at the appropriate location. The procedure was found to enhance greatly the editorial capability for the information screens available with the Library Online Catalog

9Hecht, M.L. ; Larkey, L.K. ; Johnson, J.N.: African-American and European-American perceptions of problematic issues in interethnic communication effectiveness.
In: Human communication research. 19(1992) no.2, S.209-236.
Abstract: African American and European American perceptions of interethnic communication effectiveness were compared. Interethnic communication was conceptualized as a problematic event (perceptually organized into communication issues). Hypotheses proposed that ethnic identity would predict conversational issues which, in turn, would predict satisfaction. 9 issues salient to communication were derived from previuos research: powerlessness, stereotyping, acceptance, goal attainment, authenticity, understanding, expressiveness, shared worldview, relational solidarity, and relaxation. The hypotheses were tested for differences between African Americans and European Americans with additional tests for relationship closeness. Confirmatory factor analysis, supported the factorial validity of the issues and indicated that identity had both political and social dimensions for African Americans but only a single dimension for European Americans. Path analysis did not support the causal ordering. However, when the causal link between identity and issues was eliminated and satisfaction was regressed on the entire set of predictor variables the multiple Rs were above 91% for both ehtnis groups. Different issues were associated with satisfaction for each group and for close and distant relationships for each ethnic group
