The objectives of the present study are to investigate the activity of Iranian scholars in the medical sciences in ResearchGate and to explore the effect of each of the four ResearchGate metrics on the RG score. Moreover, the citation metrics of the faculty members in Scopus and the relationship between these metrics and the RG score were explored. Methods: The study population included all SBMU faculty members who have profiles in ResearchGate (N=950). The data were collected through ResearchGate and Scopus in January 2021. The Spearman correlation coefficient was applied to examine the relationship between ResearchGate metrics and Scopus indicators as well as to determine the effect of each ResearchGate metric on the RG score.

Methods: The term "MERS" was searched in Google, Yahoo, and Bing search engines. The readability of the first 30 results for each search engine was evaluated by using the five readability scales, including Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease (FRE), Simple Measure of Gobbledygook (SMOG), Coleman-Liau Index (CLI) and Gunning Fog. Moreover, the official HONcode toolbar was used to identify websites that had been officially certified by the HON foundation. Results: Almost half of the retrieved websites were governmental (44.2%). All the surveyed websites were written above the recommended level and so, their readability is suitable for those with a high school or a college degree. The mean grade level for the MERS related websites was in a similar range across the five readability scales. Furthermore, there was no associatio...

Considering the lack of research on the accessibility of Iranian medical libraries’ websites, the aim of the present study is to evaluate the compliance of the central library websites of Iranian universities of medical sciences using the latest WCAG2.1 guideline. The research includes all the 51 homepages of the central libraries of Iranian medical universities. The accessibility evaluation of each homepage performed using “Webaccessibility” automated testing tool. The Kruskal–Wallis one-way analysis of variance was performed to explore the association of the compliance score of libraries’ websites among the three categories of medical universities. The findings of the present study revealed that none of the central library websites of the Iranian medical sciences universities are fully compliant with WCAG2.1, and the mean compliance score of accessibility was 77.26 ± 5.862 percent.

To promote international and cross-cultural bingewatching research, the present article reports on the validation of these questionnaires in nine languages (English, French, Spanish, Italian, German, Hungarian, Persian, Arabic, Chinese). Both questionnaires were disseminated, together with additional self-report measures of happiness, psychopathological symptoms, impulsivity and problematic internet use among TV series viewers from a college/university student population (N ¼ 12,616) in 17 countries. Confirmatory factor, measurement invariance and correlational analyses were conducted to establish structural and construct validity. The two questionnaires had good psychometric properties and fit in each language. Equivalence across languages and gender was supported, while construct validity was evidenced by similar patterns of associations with complementary measures of happiness, psychopathological symptoms, impulsivity and problematic internet use. The results support the psychometric validity and utility of the BWESQ and WTSMQ for conducting cross-cultural research on binge-watching. Viewers of television (TV) series are currently enjoying unprecedented levels of choice and convenience. No longer dependent on linear TV programming, they can now access as many TV series episodes as they want, regardless of time and place, due to the expansion of ondemand viewing services (e.g., Netflix, Hulu, Amazon Prime) widely available on internet-connected devices. In this context, online TV series watching is increasingly becoming a major part of many individuals' daily lives (Deloitte's digital media trends survey, 2018, 2019). However, this major shift in TV series viewing patterns has also led to the emergence of binge-watching which, in the absence of a consensual definition, may be referred to as watching multiple episodes of TV series in a single sitting (Exelmans

A wide range of information with varying qualities and by authors with varying degrees of credibility has thus become accessible by the public. Most people believe that the health information available on the internet is reliable. This issue reveals the need for having a critical view of the health information available online that is directly related to people's life. The Ebola epidemic is an emergency situation in the international public health domain and the internet is regarded as an important source for obtaining information on this disease. Given the absence of studies on the trustworthiness of health websites on Ebola, the present study was conducted to assess the trustworthiness of websites which are focused on this disease.Methods: The term "Ebola" was searched in Google, Yahoo and Bing sear...

In order to use digital resources, they need the capabilities of digital technology utilizing, which is referred to as "digital literacy. However, how much effectively students can use these facilities is a subject that needs to be addressed. So, the present study intended to investigate the digital literacy level of students of the Allied medical sciences of Shahid Beheshti University of Medical Sciences. Materials and methods: This cross-sectional study was performed at the Faculty of Allied medical sciences of Shahid Beheshti University of Medical Sciences in academic year of 2016-2017 using a researcher-made questionnaire containing 23 closed questions in four sections. A total of 115 students in three educational grades: bachelor, master and the PhD grade were included in this study. Z-test was used to evaluate the relationship between internet skills and students' academic achievements if any exist. Results: Almost half of the students (51.3%) have not completed any computer courses regarding basic ICT skills. The findings showed that 41.2% of PhD students are aware of digital literacy concept; meanwhile, only 11% of bachelor students and 20.6% of master ones knew the actual meaning of this concept. The use of public search engines was a favorite alternative for finding specialized terminologies at all grades. Furthermore, there was a significant difference between the level of familiarity with the Internet and the students' grade (p≤0.05). Conclusion: Digital literacy training courses can enhance digital literacy skills significantly. Most students agreed with the inclusion of digital literacy courses in their curriculum. Therefore, they should be supported by educators and librarians in order to effectively use the Internet and information technology as well as to overcome the problems of finding and using information to gain academic achievement.

To accomplish this aim, identifying the information seeking behavior of users seems necessary. The aim of the present study was to evaluate the methods and motives of information seeking by students of allied medical sciences. The population of the study included the postgraduate students of Faculty of Allied Medical Sciences of Shahid Beheshti University of Medical Sciences accepted to the university in 2015 to 2016. The results indicated that the main motivations of students for the information seeking is first to update their professional knowledge and then to do research activities. Among the information channels used, formal channels have been given more attention. In rating the difficulties ahead in the searching for information, the lack of or unavailability of resources was identified as the most important factor. Providing more and better information on the electronic resources of the university for the graduate students could lead to the more efficient use of the existing resources and would have much success in achieving the educational and research goals. In addition, librarians need to have detailed and scientific knowledge about the information seeking behaviors of their users so that they can meet the information needs of them through providing the necessary facilities and resources using minimum time and the lowest cost.
