dc, I suspect you are just arguing for the sake of arguing again. Because this is not a controversial issue. The editor of a magazine isn't listed among the authors of every article published in his magazine.
Whats the point of your argument? Marschark is the Editor of the Journal of Deaf Studies ... Not the editor of a department. He is editor of every issue that comes out with his name as editor on the masthead. The editor's name is on that magazine, every issue, and doesn't go on the individual articles: you see the authors' names there. The editor doesn't write the piece or conduct the research. He solicits content, selects what gets published, approves the content for publication, and edits the content to whatever degree necessary for it to meet the standards of the publication.
