Abstract

Background and Aim: This paper seeks to explore the concepts of the information commons (IC). The paper provides a look at the models and characteristics of the IC. A number of projects of the IC are presented. We will discuss the situation of an existing traditional library. It makes recommendations for converting an existing library space into an IC. A number of Challenges of implementation of the IC are explored

Methods: This is a conceptual paper, so a library study approach was chosen.

Results: Academic libraries have undergone considerable massive changes over the past decade. These changes have faced the directors of libraries with difficulties and challenges in planning of the library activities. It seems that the emergence of the IC is adaptation to the changing role of the academic libraries. The IC is a relatively new concept in the Information and Knowledge Science. The IC is described as a portal through which students and faculty will access the vast amount of information resources in the world and less a place where information is kept, as focus shifts from ownership of information to access to and management of information and smart services. There are centralized access to services and technologies, contact with the users and collaborative learning play an important role.

Conclusion. No one knows what will the academic library of the future look like? Needless to say, it will be a constantly evolving information resource with knowledgeable and skilled staff that provides fast, flexible access to digital and print information resources, fosters scholarly research in a comfortable and supportive environment, and promotes cooperative learning. The IC is a first step in that direction.

Abstract

Background and Aim: The socio-cognitive theory introduced in information science by Horland and Alberchtsen. The socio-cognitive view turns the traditional cognitive program upside down. The socio-cognitive theory emphasizes on different cultural and social structures of users. Hence, the aim of the article is to explain the role of socio - cognitive theory in information retrieval (IR).

Method: The role of the socio - cognitive theory in information retrieval was determined by reviewing of relevant literature and identifying its concepts. The current research methodology is descriptive, analytical and theoretical. The research paradigm is qualitative.

Results: The results revealed that the socio - cognitive theory can affect the information retrieval (IR), information behavior and relevancy. The socio - cognitive helps classification of a particular topic in information retrieval. It can change a thesaurus to ontology. Also, it can contribute to non-linguistic factors in understanding the meaning in ontologies and it can take account into the mediating factors in information-seeking behavior.

Conclusion. The result of this study showed that we can not only examine issues related to information retrieval, relevancy and information behavior through the traditional cognitive views. We have to sure that all the cultures and social factors are examined in our studies about IR.

Abstract

Background and Aim: The current research aims to develop a literature-dependent and expert-modified model related to credibility evaluation of web information.

Methods: Regarding the approach, mixed method would be utilized. The research method then is mixed-heuristic using both qualitative and quantitative methodologies. In the first stage of the research, meta- synthesis was used as a qualitative research method. Secondly, exploring experts’ points of view was conducted by a Delphi method to develop the conceptual model identified in the first stage.

Results: Using the seven stage mode of meta-synthesis, a model was designed in four layers including concepts, categories, codes and indicators. A set of 68 indicators were incorporated into the different layers of the model. For reliability testing of the conceptual mopdel, a Delphi study was conducted in two rounds after which the comments of the experst were included into the model. Regarding the high degree of Kendall’s coeficinet of concordance about %.65 and the agreement perecentage of the most dimensions of the model higher than %90 the conceptual model was confirmed by the sample experts.

Conclusion: The conceptual model derived from the meta-synthesis and Delphi studies is a model accepted by experts and a base for future research to design some tools for related studies. The findings showed that the credibility evaluation is a concept whith different and multiple dimensions and components suitable for users, designers and policymakers to take them into consideration in design and evaluation of web resources.

Abstract

Background and Aim: Information literacy is a contextual concept that needs to be studied in different contexts like schools. Promoting reading literacy is a core instructional objectives of Persian literature curriculum and also a part of information literacy. Understanding Concept of information literacy helps us to understand information literacy in elementary schools and can implement it in information literacy Instruction and Assessment of schools.

Methods: This research is a phenomenological research that used Qualitative Content Analysis technique for analyzing Semi structured interviews and Observations. Theoretical sampling was used and three schools were selected. We interview with four Teachers and observed four classes in Fourth Grade.

Findings: based on data analyzing we can describe information literacy for language in  Fourth Grade in this phrases: “Set the scene: Make a space for thinking, reflecting and planning”, “ emerging of determining information need”, “locating and searching of information”, “information engagement”, “information Processing”, “record, organize and ethical use of information”, “Communication”, “Presentation”.

Result: based on findings, teachers highly focused on developing skills of information engagement(reading, listening, viewing), Information Processing(supplying Infrastructures of text understandings; Practice textual, audio, visual comprehension; practicing information processing in action), presenting information(in written and Unwritten format and learning how to do them). Integrating information literacy with language curriculum seems that can help to achieve language instructional objectives. The findings can be used for designing instrument of information literacy assessment and also can be used for teacher training.

Abstract

Background and Aim: The current study aimed to investigate the state of health information supply and demand on prostate cancer among Iranian medical researchers and Iranian web users during 2011 to 2015. The purpose of this study, based on infodemiology indicators, was to investigate the alignment of health information supply and demand on prostate cancer among Iranian medical researchers and Iranian web users.
Methods: A mixed method research was conducted. In qualitative part, a focus group interview was applied to the users to identify their selected keywords searched for prostate cancer in Google. The collected data were analyzed using Open Code software. In quantitative part, data were synthesized using R software in two parts. First, users’ internet information-seeking behavior was analyzed using Google Trends outputs during 2011 to 2015. Second, the scientific publication of Iranian prostate cancer specialists was surveyed using PubMed during the period of the study.
Results: The results showed that the search volume index of preferred keywords on prostate cancer have decreased from 2191 in 2011 to 1798 in 2015. Also, the findings revealed that Iranian scholars had 161 scientific papers on prostate cancer in PubMed during 2011 to 2015. Among these 161 papers, 20 records related to 2011 and 44 records related to 2015. There was no significant relationship between users’ information seeking behavior in Google Trends and the scientific publication behavior of Iranian prostate cancer specialists (p>0.05).
Conclusion: According to the results, when the search volume index of Iranian web users decreased or increased during the period of the study, the number of scientific publications had not been affected by users’ search volume. Thus, it can be mentioned that Iranian scholars had not pay enough attention to the concerns of people toward prostate cancer.

Abstract

Background and Aim: Usually, researchers who have different levels of academic degrees, are different in terms of specialized knowledge. Also, academic degree may affect the information seeking behavior of researchers. Therefore, in this study, the difference of information seeking behavior of researchers with different academic degree for “conducting the research” and “updating scientific information” was investigated.
Methods: Survey method was used to conduct the research. In order to gather data, self made questionnaire was used. We have not sampled. In total, 140 researchers (70%), out of the 200, completed the questionnaires. Data were analyzed with descriptive and analytical statistics methods and were performed using IBM SPSS 22. In order to analysis the data, Kruskal-Wallis and Friedman's tests were used.
Results: Findings showed that the use of “journal articles” (high and very high more than 90%) was a top priority of “PhD and master students” and “PhDs”. In order to access scientific information, “PhD and master students" and “masters/professional doctors” mostly used “communication and consultation with Iranian experts and researchers” (high and very high with 75%) and “personal experiences” (high and very high with 65%). While minimal use of “communication and consultation with foreign experts and researchers” (low and never with 56%) and “participating in foreign congresses” (low and never with 69%) was used by “masters/professional doctors”.
Conclusion: Just in using the "journal articles" was significant difference in order to "update scientific information" and "research" (p<0.05). “PhD and master students”, compared to other levels of education, used “journal articles” more. While, in using the “communication and consultation with foreign experts and researchers”, “participating in foreign congresses”, and “personal experiences”, there was significant differences; So that, PhDs used them more than the others.

Abstract

Background and Aim: The purpose of this research is investigating the structure of research articles in the Iranian knowledge and information science journals (peer reviewed journals). In the next step, the writing guidelines in the scientific journals websites that designed to introduce desired structure of a scientific paper are studied.
Methods: The research was survey with analytical approach. The population of the research were articles published in the Persian scientific journals of knowledge and information science field in 2013-2015 and their writing guidelines. Stratified random sampling was used and, accordingly, 245 scientific articles were examined using a research checklist.
Results: Research findings showed that the structure of the research articles reviewed are in a good condition and only in three sub-structural components i.e "theoretical foundations", "research application" and "research limitations", consistent with the desired structure is weak. About the writing guidelines, the findings showed that they are in the unfavorable condition. Some structural components i.e "brief review of the scientific literature," "rationale to the study," "aim and motivation of the research", "advantages and importance of the research", "the research time", "space of the research", "credibility (reliability) of the research tools", "reliability of the study" did not appear in any writing guidelines. The first hypothesis showed a significant difference between research journals about their matching with the desired structure of the research article. However, the overall average ratings of the articles structure in this journals are in the good condition. Also in the second hypothesis was found a significant difference between the compliance rate of writing guides and articles published in the scientific journals with the desired research article structure.
Conclusion: Due to structural weakness in the writing guidelines of Persian peer-reviewed journals studied, can be such a conclude that authors of these articles shape the article structure based on what they have been trained and not attend to the writing guidelines of the journals. From the other side, one of the reasons of the structural weakness in the structure of the articles is disregarding editors and the other practitioners of journals to offering needed help contents.

Abstract

Background and Aim: Due to recent attention to health promotion and self-care as one of the prerequisites of health services and intervention programs, health information seeking behavior research has gain increasing importance. Factors such as attention to user centered studies, context and self-care require using of methods and tools that help study people in their natural environment. However, review studies have shown the dominance of quantitative and positivist approaches in health information seeking behavior studies. This study aims at introducing episodic interview as a tool for gathering unique data from peoples’ natural lives and its application in health information seeking studies.
Method: This review article has been conducted by library method. It addresses health information seeking behavior concept and its affecting factors. It also introduces episodic interview and its underlying concepts including narration and narrative interviewing. Further, it investigates implications of applying episodic interview in health information behavior studies and eventually it discusses steps of conducting episodic interview with examples of narrations.
Findings: The strength point of episodic interview is its focus on narration of people about their lived experiences as research data which help researchers study and analyze people in a different way from conventional approaches. Implications of applying episodic interview are: 1.concentration of health information behavior studies on pattern of behavior, 2. health information seeking behavior being interwoven in everyday life, and 3. health information seeking behavior being intentional and purposeful.
Results: Episodic interview help researchers listen to the voices of different groups of people, especially whom their voice is not heard due to sickness and social and cultural conditions, a point which should be considered in designing any information and intervention services.

Abstract

Background and Aim: Health Information Prescription (HIP) means delivering right information to the right person at the right time. The present study was performed to determine the effect of HIP on caregivers' self-care ability.
Materials and methods: In order to evaluate the effect of HIP on caregivers' self-care ability the quasi-experimental study was carried out on 37 caregivers. Data collection was conducted using a checklist for evaluation of self-care ability. According to the checklist, the caregivers' information including four main domains (total knowledge about JHMS, attention to the effects of JHMS, the effective treatment activities and the quest of medical services) was scored based on a 5-point Likert scale. HIP services were then delivered. The caregivers' information was evaluated once again through the checklist and the pre and post intervention results were compared.
Finding: This study showed that the mean score of self-care ability in each of four domains including total knowledge about JHMS (p=0.001), attention to the effects of JHMS (p=0.001), the effective treatment activities (p=0.001) and the quest of medical services (p=0.001) increased significantly after HIPS.
Conclusion: Results of this study indicated that HIP can increasingly improve the caregivers' self-care ability.

Abstract

Background and Aim: Since anyone can freely share any kinds of information in the cyberspace almost without authenticity, validation information seems important. This paper examines the concept of credibility and describes and analyzes some well-known models for the evaluation of the Web credibility.
Methods: This research is a review in terms of research methodology and theoretical in terms of the goal. Data collection was using documentary method.
Results: The assessment of known models of Web Credibility including prominence-interpretation theory of Fogg, Wathen and Burkell’s model for how users judge the credibility of on-line information, Hilligoss and Rieh’s unifying framework of credibility, Sundar’s MAIN model, Metzger’s dual processing model of credibility assessment, Lucassen et al.’s revised 3S-model of credibility, and Choi new framework for web credibility showed that the systematic concept of the connection between credit key dimensions and criteria that can be used to assess the credibility of the Web exists in none of these models other than Choi and thus the templates and the theories have limited explanatory power for a comprehensive interpretation of findings of experimental studies.
Conclusion: Due to lack of imperical testing of these theoretical frameworks through standard tools on a large scale, no one was empirically supported. Thus, it is necessary to examine these frameworks empirically to improve their validity with an experimental basis.

Abstract

Background and Aim: The aim of this study was to measure the overlap of 4 local Persian search engines of Parsijoo, Yooz, Parseek, and Rismoun and to compare the capabilities of these engines in covering indexable web.
Methods: This was an applied and evaluative research. To collect data, a keyword-based method was used. First, the selected keywords were entered into the search engines and then a sample was extracted of the retrieved records. Finally, based on the existence or absence of these records in the search engines, the necessary data were gathered. Accordingly to analyze the data, inferential statistical methods were used.
Results: The relative overlap of the Parseek compared to that of Parsijoo and Parsijoo's one compared to Yooz was 26 percent on average and Parseek had the most recall. Rismoun had not any common records with the other investigated search engines. Three search engines (Parseekc, Parsijoo and Yooz retrieved 27 common records out of 225 recalled records; there was a significant difference between the relative overlap of the 4 search engines. Also, on average, Parseel, Parsigoo, Yooz and Rismoun covered respectively 38, 31, 26, and 6 percent of the indexable web. There was a significant difference between the coverage of the 4 search engines.
Conclusion: It seems that each search engine has a different indexing policy, and users need to search for more than one search engine to get comprehensive information about an issue. It can be predicted that by foraging in two search engines, Parseek and Parsijoo, one may access 70 percent of the indexable web.
