The emergence of the World Wide Web (WWW) has changed the scholarly publishing system. Today, Open Access (OA) scholarly publishing offers free access and wide dissemination for research findings anytime and anywhere as an additional value for scholarly content. Despite the potentials of OA publishing, its adoption and use is still low. This paper determines factors influencing the adoption and use of OA publishing by academic staff in universities in Nigeria using an adapted Unified Theory of Acceptance and Use Technology (UTAUT). The study applies methodological triangulation by combining quantitative and qualitative approaches. The empirical data were collected from 317 academic staff in universities in southwest Nigeria. The questionnaire forms were analyzed using the Statistical Package for Social Sciences (IBM-SPSS) 19.0 version to generate descriptive statistics, Analysis of Variance, and Hierarchical Multiple Regression. Thematically, analysis also applies to the interviews. The results show that awareness, attitude, performance expectancy, Internet self-efficacy, and facilitating conditions significantly influenced the adoption and use of OA publishing. The study also reveals that due to lack of OA policy, most of the respondents did not know about OA. The findings further establish that all predictors and moderating variables jointly contributed 64.4% total variance towards the adoption and use of OA publishing. One of the implications of this study is that there is a need for adequate facilities to support adoption and use of OA publishing. The findings inform the proposed framework for improving and evaluating the adoption and use of OA publishing. The findings also have theoretical, societal, and methodological significance to all stakeholders.

AbstractObjective -This study has the objective of establishing whether the undergraduate students of the Faculty of Natural Sciences, University of Jos, have access to and use Internet facilities in the University library.Methods -A survey research design was adopted for this study and questionnaires were used in gathering data. Statistical methods used in the analysis include percentages, frequencies, and Chi-Square test for measuring the association of library visit and use of the Internet.Results -The analysis of the data and findings indicated that there is Internet connectivity in the library. The findings also revealed that few students (15.5%) use the computer and the Internet on a daily basis. The problems of slow Internet connection at peak periods and unsteady power supply were clearly identified. Furthermore, the analysis revealed that there is no association Evidence Based Library and Information Practice 2015, 10.4 157 between the students' library visits and their use of the Internet for most academic purposes, except for downloading articles.Conclusion -The presence of Internet connectivity in the library, does not translate to meaningful academic behaviour among the students. Therefore, sensitising and training of the students on Internet usage were recommended for better academic performance and life-long learning.
