In this study we examined the effects of 3 hypertext topologies—hierarchical, nonlinear, and mixed (hierarchical structure with cross referential links)—on the navigation performance of participants with high and low prior knowledge of the text topic. After reading the text, participants used the document to find the answers to 10 questions. After a filled distraction period, participants returned to the document to answer 10 more questions. The results showed that participants in the mixed condition performed better than those in the other 2 conditions and that the performance of knowledgeable participants was superior to that of nonknowledgeable participants. These results are discussed in relation to the ways in which text structure interacts with background knowledge of the user in enhancing or impeding performance. Actual or potential applications of this research include the design and implementation of hypertext systems for users with different levels of familiarity with the subject matter of the text.

It is important that modern IS decision making is accomplished using a systematic evaluation of research. A Model Driven Systematic Literature Review (MD-SLR) was used to examine the factors that influence e-commerce adoption readiness of Small and Medium Enterprises (SMEs) in developing countries. An initial review of commonly used theories of e-commerce adoption and e-readiness assessment theories was conducted to provide the model driving the MD-SLR. During the MD-SLR evidence was sought from all relevant empirical qualitative studies identified to refine the initial model based on evidence. The evidence supported the existence of internal SME factors (such as: awareness, commitment, technological resources, size of organisation, business resources, social relationship, relational complexities and human resources) and external factors (such as government readiness, market forces, supporting industries). New factors emerged: power supply instability, social and relationships, family support, political uncertainty, and cultural issues.
