What are the motifs in The Eskimo Connection by Hisaye Yamamoto?

There is an undercurrent of violence in the story, beginning with the fact that Alden is in a federal penitentiary. Emiko does not know why he is there, but a particularly dark and bloody short story he has written gives her the idea that he has murdered two relatives. As well, Emiko reports being "pummeled by a dear friend" who did not appreciate Emiko's response to her poem; and Emiko's daughters are seen in a brief scene in which one drags the other around the house by her hair, "rebelling at last against her sister's authoritarianism."
