Not that it makes a difference on the outcome.
The writers, photographers, etc... would be paid on a per story, picture etc... price. Most of them would be freelancers or regular folks. They may have had a few writers that they had on contract, although they would also be paid per article. The per article price is not that much. Sometimes 50.00 and I have seen up to 500.00. 500.00 per article would be in a high subscription magazine, with the writer providing all pics, and the article is edited beforehand.
Photos for magazines (periodicals ) are usually provided with the article by the writer. If the writer does not provide photos they are paid much less per article as the periodical has to go source the photos. There are professionals that can/will supply photos although their photos are provided at a premium.
Subscriptions and mailings are outsourced. I am sure there are some mom/pop magazines that do all of this without outsourcing. I believe that the percentage is so small that it is irrelevant. It is to cumbersome for a publishing group to handle on their own, so they outsource it.
With it being a new title, they would not have audited numbers to show their potential advertisers. In other words they are unable to verify how many paid subscribers they have. Since they dont have audited numbers their ad rates would need to reflect that. Meaning the advertiser revenue would be lower vs a magazine that has audited numbers.
I would imagine that their ad revenue did not cover their expenses, and like so many other magazines, the publisher closed that title, and has already moved on to the next.
There should be a number of extra copies of the magazine available at the publishing house. They would keep boxes of them to include with their "media kit" that they would send to potential advertisers. So if you contact the publishing house, and were to find someone willing to help, I would think they could send you copies of the back issues that have already been printed. Or they could have thrown them in the garbage to make room for the next title.
