My understanding is that a journal usually publishes one volume in a year.
So, why does JAL (The Journal of Advances in Linguistics) publishes 3 volumes in just 4 months?
That’s because as a new journal started in January of 2014, it tries to look more established than it really is.
And if you look at the articles published in this journal, you will find most papers are really of very poor, low quality.
