During the recent years, one of the issues considered by the banks in the field of internet banking is the adoption of corporate internet banking (CIB) by corporate clients. The present article tried to examine the factors affecting adoption of CIB by corporate clients based on the perceived risk theory. The research hypotheses were tested using confirmatory factor analysis and the results showed that there was a significant relationship between all the risks and intent to adopt CIB by the corporate clients of the banks. The major factors decreasing the intent to adopt internet banking include performance, privacy, security, financial, time, and social risks respectively. Based on the findings of the present study and similar studies, a comparison was made between the importance of the dimensions of perceived risk in personal and CIB and suggestions were made for decreasing the effects of these significant risks for the corporate clients to adopt CIB. © 2017 Springer Science+Business Media New York

This article approaches scene classification problem by proposing an enhanced bag of features (BoF) model and a modified radial basis function neural network (RBFNN) classifier. The proposed BoF model integrates the image features extracted by histogram of oriented gradients, local binary pattern and wavelet coefficients. The extracted features are obtained in a hierarchical multi-resolution manner. The proposed approach is able to capture multi-level (the pixel-, patch-, and image-level) features. The histograms of features constructed by BoF model are then used for training a modified RBFNN classifier. As a modification, we propose using a new variant of particle swarm optimization, in which the parameters are updated adaptively, for determining the center of Gaussian functions in RBFNN. Experimental results demonstrate that our proposed approach significantly outperforms the state-of-the-art methods on scene classification of OT, FP, and LSP benchmark datasets. © 2017 Springer Science+Business Media New York

Theory of Digital Objects (TDO) can be considered as one of the important theories for explaining distinctive attributes and social practices of digital objects. The main aim of this study is to determine the role and position of digital identifiers and digital identifier systems in social practices of TDO. Results of applying comparative evaluation method demonstrated that the digital identifier systems can be considered as a third approach called identifiable Web, among memorable and navigable web in TDO. Moreover functions, technologically-induced tensions, challenges, counter mechanisms and emerging practices of the proposed approach had been investigated in contrast with the two existing social practices approaches. Results of this study could provide new ideas to administrators and researchers of these systems for promoting them from the sociotechnical aspect. © 2017 Elsevier Ltd

Title of an article can be descriptive, declarative or a question. It plays important role in both marketing and findability of article. We investigate the impact of the type of article titles on the number of citations and downloads articles receive. Number of downloads and citations for all articles published in six of PLoS (Public Library of Science) journals (2,172 articles) were obtained from PLoS and type of each article's title (including descriptive, indicative and question) was determined as well as the number of substantive words in title (title length). Statistical difference and correlation tests were carried out. The findings showed that differences exist between articles with different types of titles in terms of downloads and citations, especially articles with question titles tended to be downloaded more but cited less than the others. Articles with longer titles were downloaded slightly less than the articles with shorter titles. Titles with colon tended to be longer and receive fewer downloads and citations. As expected, number of downloads and citations were positively correlated. © 2011 Akadémiai Kiadó, Budapest, Hungary.

Although context has been identified as the key to the manifestation of information literacy (IL), little is known about the actual context of IL in disciplinary areas. This is because disciplinary studies of IL have focused mainly on people's conceptions of IL, not on their lived teaching and learning practices. Introducing university assignments as a contextual construct for disciplinary studies of IL, this study demonstrates how students' and educators' conceptions and experiences of real university assignments and their constructive participation in conceptualization of IL helped to uncover the actual nature of information need in the discipline of geographic information science/systems (GIS) and to gain a better understanding of the concept of, and requirements for, determining information need in this discipline. Adopting an embedded case study design and a participatory approach for fieldwork, the data were mainly gathered from 27 semistructured interviews focused on GIS students' and educators' lived experiences of university assignments and their reflections on various aspects of IL in a master's degree GIS program jointly delivered by universities in the UK and USA. Each learning and teaching experience was treated as a unit of analysis. GIS assignments were found to be geospatial, technology mediated, subject free, and unique in requirements. Each characteristic uncovered a new facet for the concept of information need in GIS. Findings indicate that unless students have understood the multi-faceted nature of information need, they may fail to distinguish the various ways in which gaps may be addressed when dealing with GIS assignments. The context-to-concept approach proposed in this study can be of value to both IL researchers and practitioners who seek deeper insights into the nature of IL, especially those interested in the customization of generic models of IL to the actual needs of university programs. © 2016 Elsevier Inc.

Achieving the ultimate goals of policy-making will not be possible by using methods such as surveys. Evidence-based policy-making is a new approach in the public policy which has increased in many countries. Evidence-based policy-making is based on the assumption that decisions should be based on available evidence and rational analysis in addition to the judgments and opinions. One of the important evidences is statistics. Accurate statistics can promote the accuracy, quality and capacity of policy. According to the importance of the statistics for the evidence-based policy-making, this paper is seeking to examine the importance of the statistics for evidence-based policy-making and trying to show that the correct and efficient use of statistics leads to better policy. This paper uses mixed method for this purpose. Mixed method approach used in this paper is the sequential exploratory design that qualitative data followed by the quantitative data is collected and analysed. First, the comprehensive process framework for evidence-based policy-making is developed in the qualitative part by using meta-synthesis. Second, in the quantitative part, binomial test is used to validation of the developed framework. Data collection tool is a questionnaire and has been completed by 15 experts in the field of policy-making. Finally, the paper examines the role of information and statistics in the steps of proposed framework. © 2016, Iranian Research Institute for Scientific Information and Documentation.

This study demonstrates how case study research can be used to do a contextual and inductive study of information literacy (IL) and develop robust models of IL. First, it identifies several key characteristics of case study research as a qualified research methodology for studies that aim to build theories. Second, it rationalizes a need for case study research in the field of IL research. Drawing on that, it demonstrates how Eisenhardt's case study process was adopted to conduct a contextual study of IL and discusses the researcher's activities and tasks in each phase of the process. It uses the researcher's experience of the research journey to justify the validity and robustness of the research. This article contributes to current IL research methodologies and can be of value for LIS researchers and practitioners who wish to holistically gain deep insight into phenomena through case study research. © 2010 Elsevier Inc.

The aim of this research is to investigate the interdisciplinary relations in selected high priority areas of science and technology based on ISI data. This is an applied study using scientometric, citation analysis and network analysis methods. After identifying and extracting data from WOS, all citations of these records have been analyzed in order to determine the interdisciplinary relations and the evolution of these relationships. In order to judge the interdisciplinary of data, the results of the two approaches have been considered including 1-To determine the subject areas of the journals 2- To determine the institutional affiliation of the authors. There is a positive correlation between co-authorship and interdisciplinary approach in all studied areas. There is no significant relation between the number of citations and interdisciplinary approach. Mapping of interdisciplinary relationships in nanotechnology showed this is a unique method to discover the structural patterns of a research area.

Purpose - The main purpose of this article is to provide a focal framework with the aim of making integrated digital libraries in technical and content level of syntactic interoperability between digital libraries. Design/methodology/approach - Literature review, library research method and analytical approach were used in the first step of this research in order to design IDL framework. Then a survey of 11 Iranian digital library applications was conducted for testing the proposed framework. Finally, based on the findings, conceptual integration architecture was proposed based on the framework. Findings - Based on the literature a framework for integration of digital library applications in syntax level is proposed which includes four core layers: models, protocols, metadata formats, and context-based layer. Based on the findings of the survey, integration architecture is proposed which includes all the mentioned layers in the IDL framework. So as to decrease cost of installing the architecture, cloud base technology architecture introduced to be used inverse. Originality/value - A gap exists between research and practice in the field of integrated digital libraries. In fact this article is an attempt to cover this gap by proposing a framework that can be implemented. © Emerald Group Publishing Limited.

Purpose: The purpose of this paper is to report findings from an investigation into the conceptions and characteristics of geo/spatial information (GI) to demonstrate how exploring academics and students' conceptions of GI facilitated illumination of information literacy (IL) in the Geographic Information Science/Systems (GIS) discipline. Design/methodology/approach: Adopting an embedded exploratory case study, the data were gathered from semi-structured interviews, an open-ended questionnaire and students' reflection in an online distance learning (ODL) GIS programme. The data were analysed in light of the Grounded Theory approach. Drawing on the conceptions of GI which emerged from the study, this paper highlights several characteristics of GI and discusses their implications for IL. In particular, it compares the emergent IL competencies in the GIS discipline with those in the SCONUL model. Findings: GI was identified as geo/spatial, temporal, geo/spatially contextualised, and geo/spatially technology-mediated. According to these conceptions, GI is a constructive concept; it has multiple components which need various operations and user inputs to become geo/spatially meaningful and usable. These characteristics uncovered new aspects of IL in the GIS discipline which influence the depth and breadth of the SCONUL model. Research limitations/implications: Unlike exploratory studies of IL which focus on the IL and IL competencies to explore this phenomenon, the methodological approach taken in this study provides IL researchers with a new approach whose primary focus is on the concept of information as a key contextual element of IL. This helps one to gain a deeper insight into IL in disciplinary areas. Practical implications: The emergent aspects to the SCONUL model can be taken into consideration when designing and delivering IL programmes in the GIS discipline. Likewise, the emergent picture of IL in this study can be used by GIS educators to develop information-literate GIS learners. Originality/value: This study is original in terms of both its methodological approach and its outcomes. These can be of value to IL researchers, educators and practitioners. © Emerald Group Publishing Limited.
