<b>Adoption of Open Journal Systems (OJS) Among Nigerian Academics (TAM-Based)</b>

This study examined the adoption of Open Journal Systems (OJS) among Nigerian academics using the Technology Acceptance Model (TAM) as its theoretical framework. The specific objectives were to assess the extent of Open Journal Systems (OJS) adoption among Nigerian academics and identify key demographic and institutional factors influencing uptake, to examine the influence of perceived usefulness and perceived ease of use of core constructs of the Technology Acceptance Model (TAM) on Nigerian academics' intentions to adopt OJS, and to explore barriers and facilitators to OJS adoption in Nigerian universities and propose strategies for enhancing technology integration in scholarly publishing. A descriptive survey research design was adopted, and data were collected from 200 academic staff members across federal, state, and private universities in Nigeria using a structured questionnaire. Data were analyzed using descriptive statistics, One-Way ANOVA, and Multiple Linear Regression at a 0.05 level of significance. Findings indicate that the level of OJS adoption among Nigerian academics is moderate to low, with higher adoption observed in federal universities compared to state and private institutions. The results further show that both perceived usefulness and perceived ease of use significantly influence behavioral intention to adopt OJS, with perceived usefulness emerging as the stronger predictor. Regression results indicated that infrastructural and institutional barriers such as poor internet connectivity and inadequate technical support negatively affect adoption, while training opportunities and funding significantly enhance it. The study concludes that the adoption of OJS in Nigerian universities is shaped by both individual perceptions and institutional conditions. It recommends improved ICT infrastructure, continuous staff training, increased funding, and supportive institutional policies to enhance the effective adoption and utilization of OJS in Nigerian academia.
