Abstract

This paper proposes a diffusion model to measure the evolution of stakeholders' disaster perceptions by integrating a disaster message model, a stakeholder model, and a stakeholder memory model, which collectively describe the process of information flow. Simulation results show that the rate of forgetting has a significantly negative effect on stakeholders' perceptions and the incremental increase in the number of affected individuals has a positive effect on the maximum level of stakeholders' perceptions, but negative effect on the duration of stakeholders' perceptions. Additionally, a delay effect, a stagnation effect, and a cumulative effect exist in the evolution of stakeholders' perceptions. There is a spike at the beginning of the profile of stakeholders' perceptions in the Damped Exponential Model. An empirical test supports the validity of this model of stakeholders' disaster perceptions.

Abstract

Subject headings do not always adequately express the subject content of books and other library materials. Whether due to cataloguer error or inadequacy in the authority list, this deficiency makes it difficult for users to access information. In an attempt to solve this problem, the study evaluated the adequacy of the LoC Subject Headings assigned to the 23 books of Pierre Bourdieu, whose philosophical ideas were judged likely to form a good test of the ability of the subject headings to reflect the ideas proposed by the author. The study examined the subject headings given to 22 books, and their translations into English, Spanish, Portuguese, and German, comprising 88 records in OCLC as of Dec 91. It was found that most of the books received headings not corresponding to their content, as the headings were assigned from the functionalist paradigm. In general, LCSHs ignore the conceptual categories of other paradigms, do not match the current vocabulary used by social scientists, and are ideologically biased

Abstract

Successful subject searching depends upon the terminology of the search query. This paper compares the terminology of book titles with that of LCSH on a semantic level. Methods of analyzing titles into title phrases that serve as matching units are described. Guidelines used to choose LCSHs with the closest semantic matches to title phrases are set forth. The pairing of title phrases with semantically related LCSHs constitutes the data of the study. Categories representing the types of semantic relationships holding between pairs of terms are defined. Results of the study show that the most common semantic relationship holding between title phrases and LCSH is a hierarchical one where title phrases are more specific than LCSHs

Abstract

The proliferation of digital knowledge repositories (DKRs) used for distributed and collocated work raises important questions about how to manage these technologies. This study investigates why individuals contribute information to DKRs by applying and extending transactive memory theory. Data from knowledge workers (N = 208) nested in work groups (J = 17) located in Europe and the United States revealed, consistent with transactive memory theory, that perceptions of experts' retrieval of information were positively related to the likelihood of information provision to DKRs. The relationship between experts' perceptions of retrieval and information provision varied from group to group, and cross-level interactions indicated that trust in how the information would be used and the interdependence of tasks within groups could explain that variation. Furthermore, information provision to DKRs was related to communication networks in ways consistent with theorizing regarding the formation of transactive memory systems. Implications for theory and practice are discussed, emphasizing the utility of multilevel approaches for conceptualizing and modeling why individuals provide information to DKRs.

Abstract

Purpose - Uncovering faculty members' conceptions of Information Literacy (IL), as well as exploring their perceptions with regard to the importance given to a previously defined set of core IL competences grouped into four categories: searching, evaluation, processing and communication and dissemination. Ascertaining the possible differences among the five knowledge branches (arts and humanities, sciences, social and legal sciences, health sciences, and technical disciplines); and understanding the importance granted to a set of learning improvement initiatives by the faculty. The paper aims to discuss these issues. Design/methodology/approach - The survey was completed by a set of faculty members from the University of Granada (Spain). Data were collected using the IL-HUMASS survey. The research is based on subjective data, first approached from a descriptive point of view. Later, data correlation, analysis and non-parametric tests were used with the goal of finding significant differences of faculty perceptions among the relevant academic areas. Findings - Results suggest that more than half of the surveyed faculty have what the authors define as an Academic Concept of IL. The IL categories of communica\tion and dissemination and searching were graded in significance by the staff as being "very important," while those of evaluation and processing were assigned a slightly lesser rating of "important." Results suggest that IL awareness falls into two broad groups differentiated by subject discipline: those from health sciences, social and legal sciences and arts and humanities representing the first group, and sciences and technical disciplines the other. Research limitations/implications - This approach address the subjective status of faculty concepts in a single university, but also in all knowledge branches. Future research is needed. Originality/value - This is one of the few papers regarding faculty perceptions of IL.

Developments in information technology have led to changes in the mode of delivery of library services, and in the perceptions of the role of librarians in the information-seeking context. In particular, the proliferation of electronic resources has led to the emergence of new service paradigms and new roles for librarians. The Gateway Library at Penn State University (PSU) is an electronic library in transition, with new technology-based services evolving to address the ever growing and changing needs of the academic community. It facilitates access to and navigation of electronic resources in an integrated technology environment.

Abstract

Political sentiment analysis using social media, especially Twitter, has attracted wide interest in recent years. In such research, opinions about politicians are typically divided into positive, negative, or neutral. In our research, the goal is to mine political opinion from social media at a higher resolution by assessing statements of opinion related to the personality traits of politicians; this is an angle that has not yet been considered in social media research. A second goal is to contribute a novel retrieval-based approach for tracking public perception of personality using Gough and Heilbrun's Adjective Check List (ACL) of 110 terms describing key traits. This is in contrast to the typical lexical and machine-learning approaches used in sentiment analysis. High-precision search templates developed from the ACL were run on an 18-month span of Twitter posts mentioning Obama and Romney and these retrieved more than half a million tweets. For example, the results indicated that Romney was perceived as more of an achiever and Obama was perceived as somewhat more friendly. The traits were also aggregated into 14 broad personality dimensions. For example, Obama rated far higher than Romney on the Moderation dimension and lower on the Machiavellianism dimension. The temporal variability of such perceptions was explored.

Abstract

This investigation examines perceptions of normality emerging from two distinct studies of information behavior associated with life disrupting health symptoms and theorizes the search for normality in the context of sense making theory. Study I explored the experiences of women striving to make sense of symptoms associated with menopause; Study II examined posts from two online discussion groups for people with symptoms of obsessive compulsive disorder. Joint data analysis demonstrates that normality was initially perceived as the absence of illness. A breakdown in perceived normality because of disruptive symptoms created gaps and discontinuities in understanding. As participants interacted with information about the experiences of health-challenged peers, socially constructed notions of normality emerged. This was internalized as a "new normal." Findings demonstrate normality as an element of sense making that changes and develops over time, and experiential information and social contexts as central to health-related sense making. Re-establishing perceptions of normality, as experienced by health-challenged peers, was an important element of sense making. This investigation provides nuanced insight into notions of normality, extends understanding of social processes involved in sense making, and represents the first theorizing of and model development for normality within the information science and sense making literature.

Abstract

Reports results of a naturalistic study to examine the role of non verbal communication in academic libraries. Library users with information needs face the choice of trying to find the solution themselves or asking a librarian for assistance. This decision to approach or not approach a librarian and engage in interaction was studied through use of Mehrabian's immediacy metaphor. It was hypothesized that the non verbal behaviour of the librarian is related to the user's decision to approach. Data were collected through observation and interviews from 2 academic libraries: 1 college and 1 university. The investigator observed reference interactions for 37 hours, interviewing 155 users who approached 34 librarian volunteers during this observation period. Content analysis of data resulted in the identification of 5 categories indicated by users to have been critical in their choice to approach one librarian over another: initiation; availability; familiarity; proximity; and gender. Non verbal behaviours important in users' perceptions of approachability were identified. Eye contact was the most frequently mentioned behaviour that signalled to the user that the librarian was approachable

Abstract

Domain analysis reveals the contours of knowledge in diverse discourse communities. The Dublin Core Metadata Initiative (DCMI) conferences represent the cutting edge of research in metadata for the digital age. Beak and Smiraglia (2013) discovered a shared epistemology revealed by co-citation perceptions of the domain, a common ontological base, social semantics, and a limited but focused intent. User groups did not emerge from that analysis, raising an interesting question about the content of core thematic extension versus a highly granular intension. We analyzed keywords from the titles by year to identify core and granular topics as they arose over time. The results showed that only 36 core keywords, e.g. "Dublin Core," "Metadata," "Linked Data," "Applications," etc. represents the domain's extension. However, there was much rich terminology among the granularity, e.g., "development," "description," "interoperability," "analysis," "applications," and "classification" and even "domain" pointed to the domain's intension.

Abstract

Although the navigability of digital interfaces has been long discussed as a key determinant of media effects of web use, existing scholarship has not yielded a clear conceptual understanding of navigability, nor how to measure perceived navigability as an outcome. The present paper attempts to redress both and proposes that navigability be conceptually examined along three dimensions, namely, logic of structure, clarity of structure, and clarity of target. A 2?×?2?×?2 factorial between-subjects experiment (N?=?128) was conducted to examine distinct contributions of these dimensions to perceptions of a nonprofit website. The results showed significant effects for logic of structure and clarity on perceived navigability, while logic of structure and content domain involvement affected attitudes toward the website.

Abstract

By reference to the service management literature and by using the repertory grid technique, develops a set of service attributes which give a good indication of user perceptions of information systems success. Examines their relationship with the nature of the organisation, the level and involvement of users, and the kind of system to which they relate. There is no single overall set of attributes that relate to user perceptions of success, but it is possible to find subsets that do. The measurement and analysis of these attributes are helpful in setting management policies and guidelines for the improvement of perceptions of information systems success

Abstract

Investigates the effects of 2 hypermedia interface design strategies on learner efficiency, perceptions of usability, and performance. Compares these effects in relation to 2 tasks involved in reading to prepare for writing an essay - comprehending information and locating information. Findings support the use of manual and visual filtering tools in order to increase effiency and perceptions of usability
