In 1992 neurophysiologists [20] found a new type of cells in areas V1 and V2 of the monkey primary visual cortex, which they called grating cells. These cells respond vigorously to a grating pattern of appropriate orientation and periodicity. Three years later a computational model inspired by these findings was published [9]. The study of this paper is to create a grating cell operator that ha...

Connor et al. (2008) mention “specifying textual requirements of genres” (p.12) as one of the reasons which have motivated researchers in the analysis of writing. Members of each genre should be able to produce and retrieve these textual requirements appropriately to be considered communicatively proficient. One of the textual requirements of genres is regularities of specific forms and content...

SUMMARY Within the mode of "biomythography" that owes its identification as a genre to Audre Lorde's ZAMI,Jewelle Gomez examines her own writing processes. Her explorations revolve around her work-in-process about her great grandmother's life. Issues of truth, memory, history, race, and community are considered. The author also discusses the embodied nature of writing.

Mandelbrot, The Fractal Geometry of Nature (1982). In his Masterpiece, Benoit provides both a mathematical model and a description for many of the seemingly complex forms and patterns in nature, showing that fractal patterns are extremely famili...

Writing is a rhythmic activity. The nature and frequency of the rhythms depend on, among other factors, the disposition of the writer, the type of text, the external representations, and the writer’s tools. The computer encourages new rhythms of writing. The easy ability to make lowlevel revisions with a word processor may lead a writer to oscillate rapidly between composing and revising, and t...

This article addresses the issue of student writing in higher education. It draws on the findings of an Economic and Social Research Council funded project which examined the contrasting expectations and interpretations of academic staff and students regarding undergraduate students' written assignments. It is suggested that the implicit models that have generally been used to understand studen...

This study examined the effects of an innovative comprehensive writing program in upper primary education on students’ writing performance and on teachers ́ classroom practices, beliefs and skills. The program focused on the communicative nature of writing, on writing as a process, and on explicit teaching of five genre-specific writing strategies. It was implemented by 43 teachers in their regu...
