Question Author
The preamble reads (now):
As this is the international edition of The Actuary, this puzzle celebrates ACTUARIES 9 BORDERS which facilitates the provision of TEMPORARY SERVICES through the VOLUNTEER efforts of MEMBERS in areas with a lack of RESOURCES and contributes to AWARENESS of the profession and the spread of EDUCATION.
Number 9 is: "Lacking humour, call for beheading (7)" so it has to fit in that sentence neatly.
