Seven source-scoped profiles

18 September 2026 · Release 0.24

Seven submitted names now have entries linked to specific publications, institutional records, or practitioner accounts. Twelve new statements identify authorship, contributions, institutional roles, collaboration, or reported use of a method.

• Allenna Leonard: Allenna Leonard is a practitioner of organisational cybernetics. Her 2014 conference biography describes using the Viable System Model and Team Syntegrity and working with Stafford Beer. The American Society for Cybernetics records her presidency in 2002-2004. Submission and remaining claims.
• Judith Rosen: Judith Rosen contributed an introduction and a short story about Robert Rosen to the second edition of his Anticipatory Systems (2012). Springer identifies Robert Rosen as the book's author. Submission and remaining claims.
• Michael Lissack: Michael Lissack served as president of the American Society for Cybernetics from 2014 to 2020, according to the society's record of past presidents. Submission and remaining claims.
• Peter H. Jones: Peter Jones works in systemic design, healthcare design, and dialogic inquiry. OCAD University's sLab profile names him as a co-founder of the Systemic Design Association. Tecnológico de Monterrey announced his arrival in its Faculty of Excellence in March 2024. Submission and remaining claims.
• Timothy F. H. Allen: T. F. H. Allen co-authored Hierarchy Theory: A Vision, Vocabulary, and Epistemology with Valerie Ahl (1996). The contents of The Ecosystem Approach also credit Tim Allen with a chapter on scale and type. Submission and remaining claims.
• David L. Hawk: David L. Hawk wrote the 2020 proceedings paper Socio-technical-natural systems thinking. Its abstract revisits socio-technical concerns through industrial activity's environmental context and identifies Trist's work as a point of departure. Submission and remaining claims.
• James J. Kay: James J. Kay worked in environment and resource studies at the University of Waterloo. The Ecosystem Approach credits him with chapters on systems thinking, system description, and management, and a joint chapter with Michelle Boyle on self-organising, holarchic, open systems. Submission and remaining claims.

What this pass establishes

Judith Rosen's contributions are identified separately from Robert Rosen's authorship. Hawk's discussion of Ackoff and Trist does not establish a teacher-student relationship. Allen's co-authorship retains Valerie Ahl's credit. Institutional announcements are dated rather than treated as permanent appointments.

Prepared with AI assistance from the linked sources. Independent specialist review is not recorded. The full books and papers have not been read in this pass, and the wider submitted claims remain open. These entries provide documented starting points for that work.
