*Abstract*
Information systems (IS) studies regularly assume linearity of the
variables and often disregard the potential non-linear theoretical
interrelationships among the variables. The application of polynomial
regression and response surface methodology can observe such non-linear
theoretical assumptions among variables. This methodology enables to
examine the extent to which two predictor variables relate to an outcome
variable simultaneously. This paper utilizes the expectation confirmation
theory as an example and provides a methodological commentary that
illustrates a step-wise process for conducting a polynomial regression and
response surface methodology.

AJIS publishes high quality contributions to the global Information Systems
(IS) discipline with an emphasis on theory and practice on the Australasian
context.

Topics cover core IS theory development and application (the nature of
data, information and knowledge; formal representations of the world, the
interaction of people, organisations and information technologies; the
analysis, design and deployment of information systems; the impacts of
information systems on individuals, organisations and society), IS domains
(e-business, e-government, e-learning, e-law, etc) and IS research
approaches.

Research and conceptual development based in a very wide range of
epistemological methods are welcomed.

All manuscripts undergo double blind reviewing by at least 2 well qualified
reviewers. Their task is to provide constructive, fair, and timely advice
to authors and editor.

AJIS welcomes research and conceptual development of the IS discipline
based
in a very wide range of epistemologies. Different types of research paper
need to be judged by different criteria. Here are some assessment criteria
that may be applied:

•       Relevance - topic or focus is part of the IS discipline.
•       Effectiveness - paper makes a significant contribution to the IS
body of knowledge.
•       Impact - paper will be used for further research and/or practice.
•       Uniqueness - paper is innovative, original & unique.
•       Conceptual soundness - theory, model or framework made explicit.
•       Argument - design of the research or investigation is sound;
methods appropriate.
•       Clarity - Topic is clearly stated; illustrations, charts & examples
support content.
•       Reliability - data available; replication possible.
•       References - sound, used appropriately, and sufficient –
appropriate AJIS articles referenced
•       Style - appropriate language, manuscript flows.

This journal provides immediate open access to its content on the principle
that making research freely available to the public supports a greater
global exchange of knowledge.

AJIS has been published since 1993 and appears in the Index of Information
Systems Journals, is ranked "A" by both the Australian Council of
Professors and Heads of Information Systems and the Australian Business
Deans' Council.

In addition to web distribution, AJIS is distributed by EBSCO, it is listed
in Cabell's International Directory and is indexed by EBSCO, Elsevier,
Scopus and the Directory of Open Access Journals.

Thanks for the continuing interest in our work,

Cheers
