‘The mapping of an initiation of activities of a group that perform… and return…’

[Tamara]

Hi

The mapping of a parallel initiation of Activities of an Integral Activity Group that perform a distinct function and return to the initiating Activity.

Could you say:

1. Which noun the verbs ‘perform’ and ‘return’ relate to? ‘mapping’ or ‘group’?

2. Why ‘perform’ not ‘performs’ (in my view it’s only possible if the verb/the that-clause relates to the noun group ('an Activity Group') that is taken as a set (of whatever it can consist of – people, processes, activities…). As 'plural'.

?

Hi Tamara,

1.A quick look at your sentence makes me think that your verbs refer to ' (Activities )of an Integral Activity Group '
2. I think perform is used to emphasize the idea of plurality.

Hi,

The very use of the relative 'that' shows its relationship with the preceding noun 'Group'.

That isn't a complete sentence, Tamara. Is it some kind of definition or lengthy title?

To me, perform and relate both seem to refer to "Activities".

Maybe but you can't have 'that' referring back to a noun other than the one coming immediately before, I respectfully submit.

Yes, Amy, it’s a definition. The full one.

3.1.7 Invocation: The mapping of a parallel initiation of Activities of an Integral Activity Group that perform a distinct function and return to the initiating Activity. Contrast with: Instance; Iteration. See also: mapping.

This moment and from the point of basic understanding, for me it’s only important to know that it (the clause) does not relate to ‘mapping’ (the 'subject'), in any case.

Hi Alan

I didn't say I liked Tamara's latest techie "sentence". I simply gave my opinion about what I thought the author was trying to refer to.
