Question: In 1949, Canadian news magazine Maclean's was the original publisher of "The Exiles," a science fiction story by which celebrated author?

full_context: Document 1: The Hazing: "The Hazing" is a science fiction short story by Isaac Asimov. It was first published in the October 1942 issue of "Thrilling Wonder Stories" and reprinted in the 1972 collection "The Early Asimov". Discussing the story in "The Early Asimov", the author noted that it is set in the same fictional universe as his earlier stories "Homo Sol" and "The Imaginary", but featured different characters. "The Hazing" was the thirtieth story written by Asimov, and the twenty-eighth to be published. Due to the peculiar workings of the science fiction magazine publishing industry, the story appeared a month before "The Imaginary".
Document 2: The Autumn People: The Autumn People is a mass-market paperback collection of comic adaptations of eight short horror and crime stories by Ray Bradbury, gathered from the pages of the EC Comics comic books of the 1950s. It is one of five EC collections published by Ballantine Books between 1964 and 1966 (the others are "Tales from the Crypt", "The Vault of Horror", "Tales of the Incredible" and "Tomorrow Midnight"), and one of two made up of comic adaptations of Bradbury's work (the other is "Tomorrow Midnight"). The presentation of the material is problematic at best, since the color comic book pages are represented in black and white and broken into horizontal strips to fit the mass-market paperback format. Still, the collections are historically important. They were the first attempt to resurrect the EC comics, only a decade after public outcry had driven them off the racks. They were the first introduction of those comics to a generation of readers too young to remember them in their first run.
Document 3: List of Ender's Game series short stories: There are various sources for short stories set in the Ender's Game series. One is the short story collection "First Meetings" by Orson Scott Card. This collection contains the original novelette "Ender's Game" plus three other stories. Another source is Card’s webzine "InterGalactic Medicine Show". The first four stories from Card's webzine: "Mazer in Prison," "Pretty Boy," "Cheater," and "A Young Man with Prospects," also appear in the paperback anthology "Orson Scott Card's InterGalactic Medicine Show". Reprints of short stories in the Ender's Game series can be found in other science fiction anthologies.
Document 4: McKinsey Quarterly: The McKinsey Quarterly is a business magazine for senior executives focused on management and organizational theory. It is written primarily by McKinsey consultants and alumni, with some guest authors. It also publishes research from the McKinsey Global Institute, which was founded in 1990 and conducts original research on economic issues. The magazine is published quarterly and has one special issue each year. McKinsey clients are given early access to upcoming issues. McKinsey & Company provides two awards each year for articles that had the greatest impact on management based on the assessment of a panel of judges from the business community. The magazine was founded in 1964. It was initially an internal document at McKinsey & Company shared with consultants and clients, until it was published more broadly in the 1990s. It is also indexed in "Business Periodicals Index."
Document 5: The Imaginary (short story): "The Imaginary" is a science fiction short story by Isaac Asimov. It first appeared in the November 1942 issue of "Super Science Stories" and was reprinted in the 1972 collection "The Early Asimov". Following the sale of "Half-Breeds on Venus", which was a sequel to "Half-Breed", Asimov suggested to "Astounding Science Fiction" editor John W. Campbell that he write a sequel to the story "Homo Sol". Campbell was unenthusiastic, but agreed. Since "The Imaginary" lacked the human-alien conflict that he had liked in the earlier story, Campbell ultimately rejected it. "The Imaginary" was the twenty-first story written by Asimov, and the twenty-ninth to be published. Due to the peculiar workings of the science fiction magazine publishing industry, "The Imaginary" appeared a month after the third story in the Homo Sol Trilogy, "The Hazing".
