Introduction to DIASS (Disciplines and Ideas in the Applied Social Sciences) The subject “Disciplines and Ideas in the Applied Social Sciences (DIASS)” introduces students to how social science theories and concepts are used in real life to address human, social, and community issues. It bridges the gap between academic knowledge and practical application — showing how ideas from fields like sociology, psychology, and anthropology help professionals make positive changes in society. Through this subject, students learn how the applied social sciences —such as social work, counseling, and communication —use the methods and insights of the social sciences to solve real-world problems and improve human relationships .
