Belau Olatunde  Gbadamosi 《美中教育评论》2011,(5):711-717

The paper examines the level of library automation and virtual library development in four academic libraries. A validated questionnaire was used to capture the responses from academic librarians of the libraries under study. The paper discovers that none of the four academic libraries is fully automated. The libraries make use of librarians with background training in computer applications coupled with in-house and sponsored conferences and workshops. Again, none of the automation and internet equipments in these four institutions is assessed to be adequate. The paper recommends that parent institutions should give priority to the development of library automation and virtual library development through internet connectivity by voting adequate fund to this project.  相似文献

The effectiveness of post-16 pathways for gaining employment associated with undergraduate degree study     

Katy Joy 《Journal of Further & Higher Education》2018,42(7):953-968

This article sets out to examine the effectiveness of five different post-16 study pathways and the impact that spending time away from education has on gaining employment associated with an undergraduate degree. It also explores advice and guidance for students looking at post-16 study options, higher education and employment. An initial online survey was used, followed by case studies to form a mixed-method approach. The findings suggest that a vocational pathway better prepares students for making decisions around employment and study in comparison to the more traditional A Level pathway. They also highlight that a period of one to four years after finishing post-16 study and starting undergraduate degree study is the most effective for students to gain employment associated with their undergraduate degree. Finally, it was found that most participants did not have positive experiences with advice and guidance regardless of their pathway.  相似文献
