Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Beneath Raven Moon by D. Bouchard
No full textBouchard, David. (2012). Beneath Raven Moon. North Vancouver, BC: More Than Words Publishers. Print and CD. Trickster Raven is at it again in Beneath Raven Moon, a creation myth taken from the tradition of the Kwakwaka’wakw people of British Columbia. Metis author David Bouchard weaves together the enchanting tale of how keen-eyed Eagle and whimsical Raven conspire to create a love match between two young people with the story of how the Earth was given Grandmother Moon. Each page is beautifully illustrated with West Coast First Nation’s designs in the dark golds, silvers, blues and oranges of nighttime. Bouchard sets a quiet, ethereal tone for the text through carefully-paced repetition and descriptions of night time scenes. The use of playful dialogue, traditional terms such as Grandmother Moon or Grandfather Cedar and Bouchard’s placement of Trickster as a force in many aboriginal cultures enhances the timeless feeling of the text. Beneath Raven Moon derives its authenticity from its Metis author and K’omoks First Nations illustrator. Source notes are background information that places this myth in the tradition of the Kwakwaka’wakw people from BC’s Inside Passage. Each page contains both English and Kwakwala text, with the Kwakwala translation attributed to Pauline and Pewi Alfred. In keeping with First Nations\u27 oral traditions, a CD of the story read aloud in English, Kwakwala and French is included with the book. The CD also features the haunting First Nations flute music of Mary Youngblood. Students aged eight to twelve will enjoy the visual and auditory experience of Beneath Raven Moon. Recommended: 3 out of 4 stars Reviewer: Kristie Oxley Kristie Oxley is an elementary Montessori teacher at Richard McBride Elementary School in New Westminster, BC
Toxicokinetic model of the pyrethroid pesticide lambda-cyhalothrin, main exposure route and dose reconstruction predictions in agricultural workers
No full textA toxicokinetic model of the pyrethroid insecticide lambda-cyhalothrin (LCT) was developed to relate absorbed doses to urinary cis-3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropanecarboxylic acid (CFMP) metabolite levels used as a biomarker of exposure. The model then served to reconstruct absorbed doses in agricultural workers and their probability of exceeding the EFSA Acceptable occupational Exposure Level (AOEL). The toxicokinetic model was able to reproduce the temporal profiles of CFMP in the urine of operators spraying pesticides using the optimized model parameters (adjusted to human volunteer data). Modeling also showed that simulation of an inadvertent oral exposure mainly was the exposure scenario giving the best fit to CFMP urinary time-course data in applicators. With the dermal model parameters optimized from data in volunteers, simulation of a dermal exposure in applicators did not allow to reproduce the observed peak excretions and urinary metabolite levels; extremely high applied dermal doses would be required but still simulated dermal penetration rate would remain too slow. Simulation of an inhalation exposure allowed to reproduce the observed time-courses, but with unrealistic air concentrations. For applicators with the highest urinary concentrations, there was a probability of exceeding the AOEL at some points during the biomonitoring period [\u3e50% probability of exceeding for 27% of 24-h samples]; for non-applicator workers the probability of exceeding the AOEL value was very low [corresponding value of 5%]. Furthermore, the median [95% CI] estimates of 10 000 Monte Carlo simulations led to a biological reference value corresponding to the AOEL of 116 [113–119] ng/kg bw/d and 7.5 [7.3–7.7] μg/L. Overall, 7% of applicators and 1% of workers performing weeding and strawberry picking had a probability of exceeding this biological reference value. As a next step, it would be interesting to apply these methods to multiple exposure to various contaminants. Copyright: © 2024 Côté, Bouchard.

Réflexions sur la collaboration
No full textIl faut d'abord souligner que ce mémoire a été produit dans le cadre d'une collaboration entre Amélie Côté, étudiante à la maîtrise en design graphique à l'Université Laval, et moi-même, Marie-Michèle Roy, étudiante en études littéraires. Ce mémoire est divisé en quatre volets. La première partie du mémoire présente le roman dans sa version originale, sans illustration. La deuxième partie consiste en une étude du dialogue entre le texte et l'image au sein du livre illustré dans La Saveur de vide du peintre et auteur Lino, et dans Harvey. Comment je suis devenu invisible, collaboration d'Hervey Bouchard et de Janice Nadeau. Deux notions dialogiques sont développées : le dialogue de la troisième dimension et celui de la continuité. La troisième partie constitue un essai réflexif sur le travail de collaboration entre Amélie Côté et moi-même. La quatrième partie, mise en annexe, présente le résultat final : le roman illustré Sans elles

Dorsal surface of carapace and appendages white-cream scattered with brownish patches (Figs. 1 b, c). Coloration acts as camouflage, and the crabs were hardly noticeable on the substrate, when collected. Distribution. So far known only from the island of Mayotte, western Indian Ocean. Potentially also in neighbouring islands with similar biotopes (Madagascar, Comoros, Glorieuses, Seychelles) where the small size of the species may have made individuals difficult to detect. Habitat. Macrophthalmus lisae sp. nov. digs burrows on sandy mudflats. Entrances of burrows are located on the upper part of the intertidal area (Fig. 1 a); they are only few millimetres in diameter and can remained unnoticed during sampling. Etymology. This new species is named after Lisa, ten-year old daughter of the second author, for enthusiastically participating in the collections.Published as part of Poupin, Joseph & Bouchard, Jean-Marie, 2010, A new dwarf sentinel crab from Mayotte Island, western Indian Ocean (Decapoda: Brachyura: Macrophthalmidae), pp. 61-67 in Zootaxa 2501 on pages 62-65, DOI: 10.5281/zenodo.29410
