به‌کارگیری نظریه لاندبرگ و هالتن در استفاده از پایگاه اطلاعات علمی جهاد دانشگاهی (مورد مطالعه: دانشجویان تحصیلات تکمیلی دانشگاه شهید چمران اهواز)

This study aimed to investigate postgraduate students’ behavior in using Scientific Information Database (SID) through Lundberg and Halton theory. The research was done using survey and descriptive method. The population included 3491 postgraduate students at Shahid Chamran University in 2014 using Krejcie and Morgan table and stratified random sampling based on the population proportion at different faculties. Finally, 346 postgraduate students were selected as the sample. The results revealed a meaningful correlation between postgraduate students’ use behaviour and targeted use of SID. There was also a meaningful correlation between their use behaviour and the informed selection of SID. The findings indicated a meaningful correlation between postgraduate students’ use behaviour and the competition of SID with other databases. This confirms the strong correlation between the two variables and also simultaneous changes of the two variables, i.e. students’ use behaviour and the competition for the accountability of databases. Moreover, it was found that there was a significant relationship between use behaviour and meeting the information needs of postgraduate students through SID. In addition, use behaviour and value judgments of cultural intentions of SID had a significant correlation. Among the variables, the highest correlation coefficient was between informed selection and user’s behaviour (r = 0.867) and the lowest correlation coefficient was between purposeful behaviour and competition (r = 0.578).
