Krieghoff et les ceintures fléchées

Une observation scrupuleuse de toiles de Krieghoff où apparaissent des ceintures fléchées, à travers une longue expérience du tissage de la ceinture fléchée et des recherches poussées sur son histoire, m’ont amenée par ce détour à accorder à Krieghoff plus de bénéfice pour ses observations des moeurs et coutumes des Canadiens français durant ses années de résidence au Québec, 1846 et 1853, que l’ont fait certains critiques d’art. La consultation d’écrits par des visiteurs au Québec à la même époque décrivant ce qu’ils ont vu, comme H. D. Thoreau, m’a permis d’appuyer la vie du Canadien dépeinte par Krieghoff. Cela permet de considérer son oeuvre presque comme une page de notre histoire.Based on my long experience as a weaver of Assomption sashes and following extensive research into their history, my close scrutiny of paintings by Krieghoff depicting the sashes have brought me to look favourably upon his observations of French Canadian folk customs at the time of his residence in Québec in 1846 and 1853. This contrasts with the views expressed by certain art critics. Written accounts describing life in Québec by Krieghoff’s contemporaries such as H. D. Thoreau support his vision of French Canadian life. His work can thus be seen as representing a page in our history

Family violence exposure and family relationship skills in adolescents exposed to community violence

Community violence exposure has been associated with a plethora of adverse aftereffects; therefore, greater understanding of compensatory and potentiating factors associated with exposure is essential for effective intervention and prevention. The purpose of this study was to investigate the relations among school violence exposure, neighborhood violence exposure, family violence exposure, parent-adolescent relationship skills, and outcomes. Participants consisted of 100 adolescents, aged 13 to 20 years. Adolescents completed the Screen for Adolescent Violence Exposure, the Behavior Assessment System for Children- Self Report of Personality, the Child Health and Illness Profile- Adolescent Edition, and the Parent-Adolescent Relationship Questionnaire. Parents/guardians completed the Behavior Assessment System for Children- Parent Report, the Parent-Adolescent Relationship Questionnaire, and a demographic questionnaire. Hierarchical regression analyses were conducted to determine if family violence and family relationship skills in adolescents exposed to school and neighborhood violence were moderator variables in the prediction of personal adjustment, adaptive skills, psychological distress, and conduct. Results revealed that family violence exposure moderated the association between school and neighborhood violence exposure and conduct. For neighborhood violence exposure, there was no relation between exposure and conduct at low levels of family violence exposure. However, there was an inverse association between neighborhood violence exposure and conduct, including delinquent and health risk behaviors and association with deviant peers, at high levels of family violence exposure. These results indicated that family violence exposure was a potentiating factor within the environments of adolescents exposed to neighborhood violence. For school violence exposure, there was no relation between school violence exposure and conduct at low levels of family violence exposure. At high levels of family violence exposure, there was a positive link between school violence exposure and conduct, such that increased school violence exposure was related to less delinquent behavior and fewer negative peer influences. Lastly, adolescent-rated communication/problem solving skills moderated the association between school violence exposure and psychological distress, including anxiety, depression, and social stress. At more positive levels of adolescent-rated skills, the adverse impact of school violence exposure was negated. At negative levels of adolescent-rated family skills, adolescents reported more anxiety, depression, and social stress as school violence exposure increased

Effects of Exposure to Community Violence and Family Violence on School Functioning Problems among Urban Youth: The Potential Mediating Role of Posttraumatic Stress Symptoms

Adolescents who are exposed to violence during childhood are at an increased risk for developing posttraumatic stress (PTS) symptoms. The literature suggests that violence exposure might also have negative effects on school functioning, and that PTS might serve as a potential mediator in this association. The purpose of the current study was to replicate and extend prior research by examining PTS symptoms as a mediator of the relationship between two types of violence exposure and school functioning problems among ado- lescent youth from an urban setting. Participants included a sample of 121 junior high and high school students (M = 15 years; range = 13–16 years; 60 males, 61 females) within high-crime neighborhoods. Consistent with our hypotheses, community violence and fam- ily violence were associated with PTS symptoms and school functioning problems. Our data suggest that community and family violence were indirectly related to school func- tioning problems through PTS symptoms. Findings from this study demonstrate that PTS symptoms potentially mediate the relationship between violence exposure and school functioning problems across two settings (community and home). Future research should further examine protective factors that can prevent youth violence exposure as well as negative outcomes related to violence

Mechanics of the IL2RA Gene Activation Revealed by Modeling and Atomic Force Microscopy

Transcription implies recruitment of RNA polymerase II and transcription factors (TFs) by DNA melting near transcription start site (TSS). Combining atomic force microscopy and computer modeling, we investigate the structural and dynamical properties of the IL2RA promoter and identify an intrinsically negative supercoil in the PRRII region (containing Elf-1 and HMGA1 binding sites), located upstream of a curved DNA region encompassing TSS. Conformational changes, evidenced by time-lapse studies, result in the progressive positioning of curvature apex towards the TSS, likely facilitating local DNA melting. In vitro assays confirm specific binding of the General Transcription Factors (GTFs) TBP and TFIIB over TATA-TSS position, where an inhibitory nucleosome prevented preinitiation complex (PIC) formation and uncontrolled DNA melting. These findings represent a substantial advance showing, first, that the structural properties of the IL2RA promoter are encoded in the DNA sequence and second, that during the initiation process DNA conformation is dynamic and not static

Ceintures fléchées : l’envers du décor

Faut-il révéler l’envers du décor qui corrige certains mythes et légendes, et faire connaître la vérité ? Ce que nous faisons dans notre étude de quelques cas. Érasme écrit en 1509 : « Les hommes ne veulent pas être dérangés dans leurs légendes et n’aiment pas qu’on change leur vérité. » Le jugement d’Érasme reste-t-il d’actualité ? Nous traitons ici des légendes écrites par Pierre Poulin en 1897 sur l’origine des ceintures fléchées ; de la ceinture d’Isaac Brock censée lui avoir été donnée par Tecumseh ; de la toile de Thielke, en 1838, des chefs hurons portant ceinture fléchée, laissant l’impression qu’ils en sont les auteurs ; d’une ceinture au Musée Pitt-Rivers en Angleterre rapportée du Canada et censée amérindienne des plaines de l’Ouest ; de l’écrit de Cécile Barot qui a porté à confusion en notant qu’on « tresse » les ceintures plutôt que les tisser. Nous constatons qu’on ne veut pas toujours accepter l’envers du décor.Is it proper to reveal facts that correct certain myths and legends, and to uncover the truth ? This is what we are doing by examining a few particular cases. Érasmus wrote in 1509 : « Men do not want to be disturbed in their legends and do not like their truths to be challenged. » Does the judgment of Érasmus remain relevant today ? We are dealing here with legends written down by Pierre Poulin in 1897 on the origin of the Assumption sash ; with Isaac Brock’s belt supposedly given to him by Tecumseh ; with the painting by Thielke, in 1838, of Huron chiefs wearing Assumption sashes, giving the impression that they were their creators ; with a belt brought from Canada to the Pitt-Rivers Museum in England and considered to have originated among the Amerindian population of the western plains ; with Cécile Barot’s writings that cause confusion by stating that belts were « braided » rather than to woven. We conclude that the hidden side of the truth is not always easily accepted

Ceintures fléchées : iconographie 1778-1928

Cet article souligne l’importance, la popularité qu’eut une ceinture de laine colorée apparue vers 1776 éventuellement nommée ceinture fléchée. Nous avons relevé les noms de 29 artistes qui entre 1778 et 1928 ont inclus dans leurs oeuvres des personnages portant cette ceinture. Ceci confirmant ce que nous ont livré dans leurs récits de voyage ou journaux personnels des visiteurs étrangers, britanniques et allemands, décrivant la ceinture de l’habitant du Canada. Plusieurs oeuvres sont citées, titres, endroits où on peut les voir. Quelques-unes sont reproduites attestant de sa présence et de son rayonnement vers l’ouest du pays et parfois outre frontière. Ces témoignages appuient la valeur patrimoniale de cet accessoire du costume du Canadien qui eut une grande importance au pays durant de nombreuses années.This article highlights the importance and popularity of the colourful woolen sash that appeared around 1776, and was eventually named ceinture fléchée or « Assomption sash » in translation. We have been able to identify 29 artists who have included in their works characters wearing the sash between 1778 and 1928. This confirms the accounts contained in the travel logs and personal diaries of German, British and other foreign visitors regarding the sashes worn by rural Canadians. Several works are cited, along with their titles and their places of exhibition. Some reproductions of these works show how the wearing of the sash had spread to Western Canada and even across the border. These are a testimony to the long standing importance of the sash as an aspect of Canadian textile heritage

Effects of age on short-term memory for time in rats.

Working memory (WM) for event duration was investigated in four different age groups of rats (6, 12, 18, and 24 months), using a delayed, symbolic-matching-to-sample procedure. In an initial experiment, all age groups responded as though a long sample duration were a short one when retention intervals (RI) were applied. This effect is called the choose-short effect. In a second experiment, in order to test whether, in compliance with the subjective-shortening model, there would be a "shortening" of the sample duration according to the length of the RI, the psychophysical function relating the probability of choosing the long comparison stimulus to sample duration and the point of subjective equality (PSE) were determined across successive RIs in two age groups (6 and 18 months). A significant shift of the psychophysical function towards a longer duration and a significant increase of the PSE appeared as a function of the RI in 6-month-old, but not in 18-month-old rats. These results support the idea that the choose-short effect is due to a shortening of the event duration in the WM in young animals, whereas there is no evidence that the sample forgetting occurred on a time dimension in older rats

Désirs d'enfance (le corps et ses avatars chez Lewis Carroll et James Matthew Barrie)

Dans les Alice et Peter Pan, Lewis Carroll et James Matthew Barrie reconstituent leur objet de désir, étudient le corps en métamorphose, le développement du monstrueux, jusqu à l altération des enveloppes corporelles de leurs enfants rêvés qui se fragmentent et créent des doubles. Les auteurs, mus par leur désir de soumission, imposent au lecteur une vision unique de leurs œuvres, manipulent le héros en tentant de diriger la progression de sa vie et en mettant inlassablement en scène sa mort. Alice et Peter s évertuent à accéder à l incorporel pour oublier matérialité et mortalité, et leurs créateurs les dotent de traits androgynes pour nier leur sexualité et retrouver le reflet d eux-mêmes dans ces êtres. Leur corps apparaît malgré tout comme le siège de sensations charnelles et s expose au regard d un observateur amoureux et voyeur qui s interroge sur la limite qu il doit s imposer dans son fantasme de fusion avec son objet de désir.In the Alices and Peter Pan, Lewis Carroll and James Matthew Barrie form their object of desire, study the body being metamorphosed, the development of monstrosity, up to the distortion of the frames of their dream children who fragment and create doubles. The authors, driven by their will to subject someone, force a unique vision of their works on the reader, manipulate the main protagonist by attempting to direct the progress of his life and to ceaselessly stage his death. Alice and Peter try to become incorporeal in order to forget materiality and mortality; and their creators endow them with androgynous features to deny their sexuality and to find in these beings their own reflection. Nevertheless, their bodies appear as the centre of carnal sensations and expose themselves to the gaze of a loving and voyeuristic observer who wonders about the limit he has to set himself while fantasizing about his fusion with his object of desire.NANTERRE-BU PARIS10 (920502102) / SudocSudocFranceF
