Present Perfect of Past Simple?

Mo I think they're both okay, with maybe only a subtle diff in meaning. Maybe with 1) some of the publishing had come later

I hope some of our experts--and we do have some real talent here in a2k--will discuss the grammatical implications

#1 is as correct but is a bit stilted.

The present perfect is used to show that a past event still has some relevance or influence on the present, and perhaps the future.

Your sample sentences have two clauses, each with a different subject/verb. The event in the first clause, "During my career..." is still relevant to the present, as it's showing your work history/level of expertise, so the present perfect is the correct choice.

I don't think the event in which the papers were published is very relevant to the present. I would use the simple past for that clause.

I think 2) is the sentence I'd write, but I wouldn't raise an issue with anyone who thinks that the publishing of the papers is still relevant and prefers 1), either.

Thanks FBM, I'm continually impressed by youse guys

Well, in my day job I pretend to teach English, after all...

Well hell FBM I spent 60 years in the field of journ in one capacity or'nother, and I never did catch onto all those technicalities

On my first trip to Boston I was told to try fresh scrod as soon as I got there. Picked up at the airport by a cab, I asked the driver if he knew "where I could get scrod". He replied that while he'd been asked that many, many times, he'd "never been asked in the past pluperfect tense before."
