==============
|
|
UC employee title classification engine: sorts every employee into one of
|
|
8 analytical categories based on job title (and, for non-academic staff,
|
|
gross pay). Independent of any particular data source — feed it a raw
|
|
title string and (optionally) a gross pay figure.
|
|
|
|
CATEGORIES (8 total)
|
|
---------------------
|
|
Categories are organised around the UC Academic Senate membership rules
|
|
(Regents Standing Order 105.1), as listed at senate.ucla.edu/senate-membership
|
|
|
|
SENATE_FACULTY
|
|
All titles that carry Academic Senate membership (excluding administrative
|
|
officers such as Chancellor, Dean etc. which are kept in SENIOR_MANAGEMENT):
|
|
- Professor series (all ranks: Full/Assoc/Asst, all pay plans: AY/FY/HCOMP/
|
|
B/E/E/SFT-VM/Law/1-9 etc.)
|
|
- Professor of Teaching / SOE / PSOE (Senate members)
|
|
- Professor of Clinical X (all ranks) -- Senate per SO 105.1
|
|
- Professor-in-Residence (all ranks) -- Senate per SO 105.1
|
|
- Acting Professor and Acting Professor of Teaching (all ranks) -- Senate
|
|
- Instructor and Instructor-in-Residence -- Senate
|
|
- Emeritus/Recall faculty (retired from Senate title)
|
|
- AES Agronomists and Astronomers (tenure series)
|
|
|
|
NON_SENATE_ACADEMIC
|
|
Academic titles that do NOT carry Senate membership:
|
|
- Health Sciences Clinical Professor series (HS CLIN PROF) -- explicitly
|
|
listed as non-Senate; kept visible because their HCOMP supplements make
|
|
total pay structurally different from regular faculty
|
|
- Adjunct Professor series
|
|
- Visiting Professor series (including Vis Asst/Assoc Prof)
|
|
- Assistant Acting Professor (different from Acting Assistant Professor,
|
|
which IS Senate)
|
|
- Clinical Associate series
|
|
- Non-Senate Instructional / Lecturers (all variants including LECT-AY,
|
|
LECT-FY, LECT-AY-1/9, Summer Session, Continuing etc.)
|
|
- Professional Research series
|
|
- Project Scientist series
|
|
- Specialist / Cooperative Extension series
|
|
- Visiting Professional Research / Visiting Scholars
|
|
- Volunteer Clinical Professor
|
|
- Librarians, Academic Coordinators, Academic Administrators
|
|
- Postdoctoral Scholars (non-student, non-Senate)
|
|
|
|
SENIOR_MANAGEMENT -- kept as-is (anchored patterns to avoid false positives)
|
|
ATHLETICS -- kept as-is (separated to avoid inflating SMG totals)
|
|
STUDENT_TRAINEE -- TAs, GSRs, Readers, Residents, Interns, Student workers
|
|
SENIOR_PROF_STAFF -- non-academic staff, gross pay >= $100k
|
|
PROF_STAFF -- non-academic staff, $40k <= gross pay < $100k
|
|
SUPPORT_STAFF -- non-academic staff, gross pay < $40k
|
|
|
|
Pay thresholds for SENIOR_PROF_STAFF vs PROF_STAFF vs SUPPORT_STAFF are
|
|
applied to gross_pay and can be overridden per-call via classify_title()'s
|
|
senior_threshold / support_threshold arguments.
