Abstract

Objective: Data as a strategic asset in any organization requires proper and effective management to provide transformational opportunities for the organization. In this regard, data governance is seeking strategic value creation from the organization's data by identifying the policies, processes, and responsibilities related to data. Effective data governance requires evaluation, and the purpose of this research is to provide a method for evaluating data governance in organizations.
Methodology: In this research, first, a model for evaluating data governance is proposed in the form of a hierarchical structure, using the results of previous researches. Then, the evaluation method is established using the proposed structure and a hybrid approach based on Analytic Hierarchy Process and TOPSIS. The proposed approach is used in a case study in the food industry.
Findings: According to the results of this research, data governance can be evaluated from three different dimensions, including data quality, internal organizational effects, and external organizational effects. Data quality evaluation criteria include accuracy, completeness, consistency, availability, robustness and uniqueness of data. The data governance effectiveness, data governance productivity and business cost savings criteria refer to the internal organizational effects. The obtaining and improving customer satisfaction, compliance with laws and creating business opportunities criteria are also related to external organizational effects.
Conclusion: Data governance, by monitoring data quality and aligning it with business goals, is one of the causes of intra-organizational changes, such as increased productivity, in one hand and on the other hand has external impacts like increasing customer satisfaction and creating new business opportunities. Therefore, organizations need to use, implement, and evaluate data governance in their business to maintain competitive advantage and compliance with laws and regulations. This study tried to provide an applicable approach to evaluate data governance in organizations

Abstract

Background and Aim: The present investigation intends to compare and review various user interfaces from user standpoint and to ascertain its linkage with user satisfaction.

Method: The research incorporated a descriptive survey of University of Tehran graduate student body. Using a targeted sampling, graduate students from the faculties of chemistry and Biology were selected. The instruments used were: A researcher-constructed questionnaire based on Nielsen’s 10 component model; and QUIS user satisfaction questionnaire.  Each database UI were evaluated based on five indicators of general features, search features, retrieval features, display features and user-friendliness.

Results: Findings indicated that with an average of 3.88 the Elsevier database had the highest score. Users surveyed believed that the quality of user interface was in better shape than other UI. One should note that this advantage is not indicative of overall database quality and the relatively better interaction on the part of users could be ascribed to their familiarity with the said database and its resource location process.

Conclusion:  The main purpose of designing and developing a database is to accruing user satisfaction in search and retrieval process. Hence User satisfaction directly connected to user interface

Abstract

Background and Aim: The present paper discusses results of a study which aimed to explore the knowledge and use of Online social networking by MLIS students in Iran and to explore their perceptions of using that technology for academic and professional purposes, and challenges they face for using them.

Method: The research method was explorative and empirical. Data was collected through a web-based survey questionnaire containing both open and close ended question. The link of questionnaire was emailed to MLIS students in Tehran. 113 students completed the questionnaire.

Results: The results show that 35 percent of respondents were not users of SNS. Internet filtering in Iran was identified as the major barrier on using SNS by MLIS students. Negative perceptions toward SNSs were identified as another big barrier for using SNSs by MLIS students. 22% of respondents felt that social networking would waste their time and some 14% saw on benefit on online social networking. 36% of respondents trusted very little to information released in SNSs. MLIS students were not sophisticated users of social networking sites. They have good level of skills on basic features of social networking sites. However, in more advanced features of SNSs such as privacy settings their skills seemed limited. Respondents to the questionnaire showed positive feedback on using SNS for academic and professional purposes.

Conclusion: There are several advantages for integrating SNS in LIS education. Preparing students for employing those technologies on their work places upon their graduation; increasing the employability of LIS students; reaping the educational benefits that SNSs offer and preparing students to teach social networking literacy competencies to others are some of the advantages of incorporating SNSs into LIS education. Authors suggest that skills to master online social networking must be taught in LIS education

Abstract

Background and Aim: The present study aims to explore the coverage and reflection of Knowledge and Information Science news in the Iranian press. Iran Newspaper which is one of the main public newspapers in the country has been selected as the case for this study.

Method: This study used content analysis as its research methodology and adopted an inductive approach in data analysis. All the pages of this newspaper during a year (from March 2011 to March 2012), were downloaded from the newspaper website and their contents were inductively analyzed to identify Knowledge and Information Science related news.

Results: Iran Newspaper, as one of the most well-known and public press in the country, has covered the Knowledge and Information Science news with a reasonable coverage and comprehensiveness. However, the reports are mainly descriptive with less analytic perspective and there is a gap for more analytical news. The collected data were categorized into seven categories and all the concepts and subcategories were presented in the tables. The main identified categories in this study include: Tehran International Book events, other book exhibitions and cultural events, meetings and book awards, reflection of the news related to book and publication industry, scientometrics, reading and its promotion and hinders.

Conclusion: There is a gap of the news from ILISA (Iranian Library and Information Science Association) and also popular notes written by Knowledge and Information Science scholars, librarians and Knowledge and Information Science students. As a result it seems ILISA could be more active in publishing its news and use popular press to introduce this area to the public and promotes its activities in the public domains.

Abstract

Background and Aim: The purpose of this study was to investigate the extent of observing the standards of indexing (ISO 999-1996, BS 3700) of Library and Information Sciences books.

Method: The study used descriptive-analytical methodology and the population consisted of all the Persian books, written and translated, in the field of Library and Information Sciences published from 2006 to 2012 with the back-of-book index. To collect the data, a checklist based on the indexing standards of ISO 1996-999 and B.S. 3700 was used.

Results: The findings indicated that among the 424 books studied, 26% had index, while 71% lacks it. Overall, the extent of observing the evaluation criteria in the book indices in the field of Library and Information Sciences was 56%.

Conclusion: The results suggest that the extent of providing the index for the books in the field of Library and Information Sciences has a relatively optimal condition compared with those in other fields. However, considering the purposes and applications of the field of Library and Information Sciences, the standards in the indices have been poorly observed. Time-consuming nature of indexing, lack of time and accelerating pace of publishing and offering books, economic issues, lack of expert human resources, and lack of enough knowledge about the significance of index are some of the obstacles for preparing the index for the books.

Abstract

Background and Aim: Collaborative information behavior (CIB) is strongly affected by contextual factors and in different contexts we can see various aspects of collaborative information behavior. In this study, we investigate the triggers and barriers of collaborative information behavior in an educational-medical context in Iran.
Method: This qualitative research uses grounded theory as research method. Semi-structured interviews were conducted with twenty physicians (in Fellowship and Residency stages) in Shahid Beheshti University of Medical Science.
Results: the findings indicated that five main factors trigger collaborative information behavior, including lack of domain expertise, lack of time, information scatter, complexity of information needs and lack of immediately accessible information. The barriers that hinder collaborative information behavior in this context fell under five categories, technological, individual, team, educational structure and cultural barriers. Some of these triggers and barriers have identified in previous researches in different contexts.
Conclusion: the results of this study showed that Lack of time was strongest trigger of CIB in physicians (in fellowship and residency stages). Then complexity of information needs, lack of domain expertise, information scatter and lack of immediately accessible information were the triggers that identified in this study. Also barriers that identified in this context are so important. In order to promoting CIB in this context the barriers should be analysed and resolved.

Abstract

Background and Aim: The present investigation was carried out in order to study the self-archiving behavior displayed by Knowledge and Information Sciences (KIS) faculty members in Iran. It intended to discover the incentives and barriers impacting on this behavior as well as arriving at a baseline for predicting the extent of self-archiving.
Method: A descriptive survey method was deployed. The population investigated, included all KIS faculty members affiliated with universities and research centers supervised by the Ministry of Science, Research and Technology in Iran.
Results: Based on self-reporting by the population studied, the extent of self-archiving is above average.  Self-archiving in personal and corporate websites were more prevalent than institutional and subject repositories. Recognition component was the most important incentive and copyright consideration was the most important barrier to self-archiving by KIS faculty members. Among the 10 factors studied, only the professional recognition component was capable of predicting self-archiving of scientific output in open access websites.
Conclusion: KIS faculty members in Iran welcome open access of their scientific works but there is some obstacles such as copyright that removing it could help to improve current conditions.

Abstract

Background and Aim: Collaborative information seeking is an interaction among members of a group who purposefully try to access and share joint information. Although collaboration is a key component of information seeking behavior, but most of the studies in this area are focused on individual information seeking behavior and collaborative aspects are considered much less. As a result, there is a need for understanding conceptual features as well as supportive technical methods of information behavior in collaborative activities. Method: The present review article has studied concepts and theories of collaborative information behavior using library method. Results: In this research, firstly, the concept of collaboration is explained and differences with other concepts like communication, coordination and cooperation are explained. Moreover, the concept of collaborative information behavior and collaborative information seeking behavior are discussed from different viewpoints and suggestions are offered for future research. Conclusion: collaborative information behavior is one of the most important concepts in human information interaction studies and it can be known as dynamic activities in a group including searching, combining, publishing and producing information.

Abstract

Background and Aim: People refer to virtual information resources for answering their medical questions. One of these resources includes question and answering (Q&A) sites in medicine. This study aims to analyze health  questions posted on the Yahoo Answers to identify health information needs, the motivations for asking questions, evaluation of information user satisfaction resulted from received answer, the reason of using answers, the using aspects of given information and the types of selection criteria people employ when they select best answers in Yahoo! Answers. Method: A survey was conducted using an online questionnaire. Email invitations were sent to 1015 users of Yahoo! Answers and 100 users filled the questionnaire. Moreover, 500 questions, 50 from each health subject category, were subject to content analysis using MAXQDA.  Having no cost, having fun and social connection in Yahoo! Answers constitute the most important motivations for using the health group of Yahoo! Answers. The findings show that “concise answers” is considered as users’ satisfaction factor. Results: The findings showed that the concern about themselves, family, people who they care about, the lack of information and the knowledge gap, validating information from other people, the lack of social support, particularly insurance and income are among  the main reasons for users to ask questions. Prevention and health promotion, turning the guesses to certainty, consultation before treatment, surgery, or taking certain medications constitute most of the cases users use from the received answers of the questions. The Socio- emotional value was particularly a prominent criteria from User-Perspective in this study for selecting the best answer. Conclusion: According to this research, it was found that natural cure and remedies, orthodontics, losing weight methods, loosing fats, skin diseases and how to treat them, foot pain and the related problems, male genitalia, the use of eye lenses, menstruation and the problems related to the sleeping constitutes the most categories of subjects in the health part of Yahoo! Answers. The results show that most of the questions are related to a particular disorder or disease like general information, the symptoms, causes, diagnoses, treatments, prognoses of the disease.

Abstract

Background and Aim: There seems to be a conceptual link between some theories of human information behavior. These links exist because some of these theories have been derived from same theories in similar fields or have a same approach in theorizing.
Method: In this paper 3 theories of information behavior (information poverty, information overload and social capital) have been discussed and compared.
Results: Chatman’s information poverty theory pays attention to the cultural/behavioural aspect of the phenomenon and clarifies that membership within a social group contributes to information poverty. Information overload describes the situation in which one feels anxious and stressed due to encountering to too much information. Social capital is rooted in social network analysis and explains how the social resources inside one’s network influence the success of achieving desired information. Both information poverty and information overload point out information avoidance, where there exists information but access to it is restricted. Social capital and information poverty both focus on the role of social structure in information seeking and the importance of trust in society.
Conclusion: Libraries can generate social capital by presenting some social programs to help users overcome their information overload and poverty.

Abstract

Background and Aim: Image, as a kind of information vehicle which can convey a large volume of information, is important especially in medicine field. Existence of different attributes of image features and various search algorithms in medical image retrieval systems and lack of an authority to evaluate the quality of retrieval systems, make a systematic review in medical image retrieval systems field necessary. The objective of this study was to conduct a systematic review of papers on medical image retrieval systems appeared between 2000 and 2011.
Method: The major scientific databases (Medline, Scopus, Webof Knowledge (ISI), and Google Scholar) were searched, using standard keywords in English between 2000 and 2011. All papers reviewed using standard critical assessment and grading and papers with more than half of the quality scores were considered as qualified to enter to the next stage. Then, the data in selected studies were extracted and classified.
Results: Eighty sixreviewed papers were classified into 3 categories. The first category introduced new medical image retrieval systems (40%) and the second category presented a new framework for the major medical image retrieval systems (45%) and the last category was about medical image retrieval systems evaluation (15%). However, the growth rate was increasing during the period and the most papers published in 2009. The CBIR systems were used more (66%) and then hybrid systems (20%) respectively.  
Conclusion: Applying medical image retrieval systems with Decision Support Systems (DSS) and other information and computer technologies can help clinicians to present a better service and can help them in diagnosis as well. Meanwhile, these systems can be very useful in education and research, the medical image retrieval systems can be more successful if they are designed for a specific field and based on new and modern image features.
