  • User interface in Iranian children digital libraries: The expert's view and offering a proposed model
    Zeinab Sedighi, Abbas Gilvari, Fatemeh Nooshinfard Page 6
    Purpose

    This research aims to study the expert's view about the features and components of children digital libraries (DLs) user interface and propose a model in this respect.

    Methodology

    To do this descriptive survey, the related texts were reviewed and consulted. Then, criteria and components of children DLs user interface were extracted and designed in the form of a Likert’s five-point checklist. The checklist was sent for professionals, faculty members, and authors of DLs texts. The collected data were analyzed using SPSS software. To determine the threshold score for acceptance of each component in the model, T-score was used.

    Findings

    Among the criteria of the study, the experts rated ‘the error message’ with T scores 4.7 (94%) as the highest ranked component and ‘personalization of the text's with T-score 3.72 (74.4%) as the lowest ranked one. 'Personalization of resources retrieved from the library’ with a standard T-score of 4.55 (91%), and "variety of available resource formats in the library" with a T score of 4.53 (90.6%) got the second and third ranks, respectively. Finally, based on those criteria which achieved the accepted scores by the experts, a model (consisting of 15 criteria and 98 subcriteria) for children DL user interface in Iran was proposed.

    Conclusions

    It is concluded that despite the different opinions of experts regarding the components and criteria, it is possible to propose a unique and common set of criteria for children DLs in Iran.

  • Correlation between self-citation and impact factor of LIS journals indexed in Web of Science during 2006 to 2008
    Zahra Behzadi, Abdulrasool Jowkar Page 7
    Purpose

    This study investigates the correlation between journal self–citation and impact factor of journals in the field of Library and Information Science (LIS) indexed in the journal citation reports (JCR) of Web of Science (WoS) during 2006 to 2008.

    Methodology

    Citation analysis is used to conduct the research. It studies the LIS journals indexed by Thomson Reuter's database during years 2006 to 2008.

    Findings

    The results indicate a significant correlation between impact factor and journal self-citation in the level of 0.001 in LIS from 2006 to 2008. This means that with increasing self-citation, the impact factor of journals has also increased. The relation between the number of articles and impact factor in the three years showed several results; for example, in 2006 and 2008, this relationship is very weak. This reflects the influence of impact factor in the number of articles. Findings also show that synchronous self-citation rate has ascending process but diachronous self-citation has a descending process.

    Conclusion

    Self-citation is a natural phenomenon, but this factor affects the impact factor and thus the real stand of scientific journals. Hence, its role should be cautiously considered in the future evaluations.
