LCHC. The role of digital technologies in settings for education, work, and play has and continues to influence the LCHC's research and intervention agenda, as evidenced by the Fifth Dimension and UCLinks projects. LCHC researchers also use digital audio- and video-recording technology for data collection, recording real-time interaction that can be analyzed later at multiple levels. Scientific communication activities The LCHC has been directly and indirectly involved with many kinds of publication projects. It created LCHC Newsletter (1976 to 1993) to initiate an international discussion about culture in development, followed by the refereed academic journal MCA (1994 to present). It began sponsoring a listserv in the early 1980s (formerly XLCHC, now called XMCA) where scholars from all over the world discuss the issue of culture and development in a broad, interdisciplinary manner, communicating about topics such as cultural psychology, Vygotsky, cultural-historical activity theory, and more. Collaboration Owing to its basic philosophy of research, the LCHC is notable for collaboration with a wide range of researchers in different disciplines and parts of the world. Of special note is the close collaboration between the LCHC and the Center for Research on Activity, Development and Learning (CRADLE) (was Center for Activity Theory and Developmental Work Research), and its long-term support of ISCAR (International Society for Cultural and Activity Research). Hundreds of researchers have been associated with LCHC over the years and remain associated through its networking system.
