mediate the relationship between CSE and PU (CSE [right arrow] PEOU

is defined as "the degree to which a person believes that using a particular system would be free of effort" (Davis 1989).
can have impact on a user's belief about PU when using a system .
Nevertheless, there are some criticisms of the current TAM research, for instance, still few studies have been conducted to examine relevant factors influencing PU and PEOU

, ATTI, and BI to continue SNSs-based travel knowledge sharing).
TAM has been utilized in many studies and found that PEOU
and PU were significantly related to computer usage (Adams 2002; Igbaria et al.
The relationship between CSE and PEOU
has attracted a considerable attention, especially in systems acceptance and adoption research.
They showed that both training and project communication influence the shared beliefs, and shared beliefs influence the PU and PEOU
of the technology.
Examining the antecedents to PEOU
is important not only because PEOU
may affect BI both directly and indirectly, but also because it relates to users' perceptions in the early stage of using a system.
Among the studies that focused on TAM, most have followed Davis's (1989) assumption that external variables (such as gender, experience, and other demographic variables) influence technology adoption/usage through beliefs about PEOU
In summary, this paper addresses the following research questions: (1) what is the relative importance of the suggested exogenous factors on PEOU
According to the descriptive statistics results in Table8, PEOU
was the most significant variable.
