The citation style for Acta series is APA. If necessary you can use IEEE citation style in the C series. Also other citation styles can be used (B series) but agree on the matter with a series editor.
The Acta editors recommend that doctoral candidates use Mendeley for reference management, as for example use of Microsoft Word’s built-in bibliography builder causes technical and compatibility problems and unnecessary work.
You can transfer your references in RefWorks to another reference management program, such as Zotero and Mendeley.
Note that references in Word or another word processor can not be automatically converted to another reference manager.
