Eits is a work of fiction, a non-traditional novel whose structure is largely determined by an Oulipian-style constraint. The constraint in Eits is culled from the album names and song titles of the band Explosions in the Sky. Each album corresponds to a chapter in the novel, and the language of each album title must be used in some way as an introduction to each chapter. Within each chapter (album), song titles correspond to numbered sections where each title must appear as is in the first sentence of that section. This not only dictates, to some degree, the direction of the text that will follow, but, looking ahead, the title of the next section will dictate where this section must arrive. From this, a narrative naturally takes shape. Albums/chapters appear chronologically, according to each album's release date, and within each album/chapter, songs/sections appear in the order they do on the album. This is, perhaps, the most straightforward way of ordering the received language of the constraint, the possibilities beyond this exponential. Eits is a novel that shifts in form, providing a texture to the space and reading experience of the novel, all in hopes of creating a space in which content and form inform and push each other to new limits. Eits is never satisfied to settle on one form for too long, and it is in the movement between forms that the narrative develops in interesting ways. Eits demonstrates the combinatoric possibilities inherent in language, and this exploration of potential highlights the reciprocal relationship between writing and reading. As Eits builds upon a limited language set, it explores and exploits the combinatory possibilities that language allows for both writer and reader. It demonstrates that all combinatoric potentialities, visible or not, always co-exist in the same time and space, and in this infinite space, individuals are invited to be writers and readers in simultaneity.

Understanding spatial distributions and how environmental conditions influence catch-per-unit-effort (CPUE) is important for increased fishing efficiency and sustainable fisheries management. This study investigated the relationship between CPUE, spatial factors, temperature, and depth using generalized additive models. Combinations of factors, and not one single factor, were frequently included in the best model. Parameters which best described CPUE varied by geographic region. The amount of variance, or deviance, explained by the best models ranged from a low of 29% (halibut, Charlotte region) to a high of 94% (sablefish, Charlotte region). Depth, latitude, and longitude influenced most species in several regions. On the broad geographic scale, depth was associated with CPUE for every species, except dogfish. Latitude and longitude influenced most species, except halibut (Areas 4 A/D), sablefish, and cod. Temperature was important for describing distributions of halibut in Alaska, arrowtooth flounder in British Columbia, dogfish, Alaska skate, and Aleutian skate. The species-habitat relationships revealed in this study can be used to create improved fishing and management strategies.
