"This issue of 'Communication Research Trends' provides a survey of the field of sustainable social change and communication in a global context. It starts with a review of introductory works and general overviews and lists some manuals, resource books, journals, and organizations, which are relevant to the field. The second section continues with definitions that circulate in the field and provides entries to materials discussing the history of development communication and related policy and rights issues. Section three reviews approaches and is structured according to dominant paradigms, such as modernization, dependency, globalization and localization, multiplicity, and participation. The final section takes a look at practices and methodologies." (Introduction, page 4)
