coding of societal types

Replication of Pat Nolan's analyses with Ethnographic Atlas and Standard Cross-Cultural Sample. Based on description of coding of types of societies in Nolan, Patrick and Gerhard Lenski. 1999. Human Societies: An Introduction to Macrosociology. (8th edition.) New York: McGraw-Hill. Appendix pp. 419-421.

**Variables in the Ethnographic Atlas (EA) and the Standard Cross-Cultural Sample (SCCS) used to define societal types in Gerhard Lenski's typology**
EA	SCCS	Description
V1	V203	Gathering, Dependence on
V2	V204	Hunting, Dependence on
V3	V205	Fishing, Dependence on
V4	V206	Animal Husbandry, Dependence on
V5	V207	Agriculture, Dependence on
V44	V248	Sex Differences: Metal Working (Category 9 - Absent or unimportant activity, n=516)
V55	[V249] V254	Age or Occupational Specialization: Metal Working (Category 9 - Task absent or age/occupational specialization absent, n=533) Note: in the current version of SCCS this variable is V254 (V249 now concerns Weaving, not Metal Working); V254, Category 9 is described in the SCCS simply as "Activity absent", n=533
V39	V243	Animals and Plow Cultivation (Category 2 - Not aboriginal but well established at period of observations, n=18; Category 3 - Aboriginal prior to contact, n=141)
V40	V244	Predominant Type of Animal Husbandry (Category 4 - Equine animals (horses, donkeys), n=64)

Questions to Pat Nolan about definition of societal types in Appendix of Human Societies 8e (pp. 419-421):

Q1 - Steps 1 to 4 on pp. 419-420 discuss only cases in which the dependence score (on hunting and gathering, fishing, herding, or agriculture) is 6 or greater to classify societies into "hunting and gathering", "fishing", "herding", "simple horticultural" (plow absent and metals absent), "advanced horticultural" (plow absent and metals present), and "agrarian" (plow present). Then Steps 5 and 6 discuss how the dominant mode of subsistence is defined when dependence scores are 4 or 5; but there is no further discussion of how societies are then classified into "simple horticultural", "advanced horticultural", or "agrarian" according to the presence/absence of metals and the plow. My question is, should Steps 4 and 5 be performed first to determine the dominant mode of subsistence, and only then agriculture-dominant societies classified further into "simple horticultural", "advanced horticultural", or "agrarian" as described in Steps 2 and 3?
Q2 - Presence of metal working can be assessed with 2 variables (V44 and V55); V44 implies that metal working is absent in n=516 societies; V55 implies it is absent in n=533 societies. My question is, how did you reconcile information from these 2 variables in cases where it is contradictory?
Q3 - In using V39 to determine whether the plow is present, do you code both category 2 and 3 as "plow present", or only category 3?
Q4 - I wonder of you have kept a listing of the program used to create the societal types, in any language, as it would help a great deal in answering these questions and duplicating your coding successfully.
