<p class="Pa2">This journal is now to be known as UIC Research Journal International Edition. Nothing is really changed except that the Editorial Board has tapped some international reviewers to help evaluate and determine the scholarly merits of the papers submitted for publications. Thus, aside from the Filipino scholar reviewers who edit the manuscripts, six foreign-based experts also appraised the papers. Since the articles have already been critiqued by Filipino scholars at the specific areas of expertise, what the international reviewers actually did was to judge mainly the over-all quality of the journal article. For this issue, the following criteria were observed by the international referees: Technical Soundness - 30 percent, for the presentation, organization, and over-all appearance of the research article as a piece of technical write up; Readability for International Setting - 30 percent, for the acceptability of the research articles to non-Filipino readers, in terms of language, practices, level of technology and methods, laws, and culture in general; and Scholarship Quality – 40 percent, for the substance, writing style, editing, and relevance and timeliness of the research article. We would like to thank all the international reviewers who took time in helping us evaluate the papers included in this particular issue. Your generosity is priceless! A million thanks!</p> <p class="Pa2">This journal presents the articles of faculty researchers not only from UIC but also of other universities and colleges in Davao City, Philippines.
