Abstract: This investigative analysis bases itself on an array of documentary material from the archives of the Imperial War Museum in its effort to recover the intricate story behind the two British volunteer nurses who made their name during the First World War with the first-aid station they set up in Pervyse, a mere stone's throw away from the Belgian firing line. The essay juxtaposes a variety of documentary sources—the unpublished diaries of the two women, Geraldine Mitton's reconstruction of the story out of the nurses' journals and letters in The Cellar-House of Pervyse (1916), and two photograph albums, ‘The Women of Pervyse’, bequeathed to the Imperial War Museum—in a quest to understand how the two nurses came to acquire their status of national heroines. Sifting through the source material, this investigation reveals the numerous inconsistencies and gaps that exist between the published and the unpublished accounts of the dressing station, whose true genesis is obscured by several competing narratives. A close reading of Mitton's account and the photographic portraitures discloses that neither of these documents ought to be taken at their face value. They need to be understood as valuable tools in the nurses' own battle for authority, public recognition and their opportunity to feature as genuine protagonists in the arena of war.  相似文献

A simple aqueous extraction method for the isolation and identification of psilocin from Psilocybe cubensis mushrooms is reported. This method employs a dephosphorylation of the phosphate ester to psilocin, which facilitates a greater product yield and simplifies identification. Psilocin extracted by this method is sufficiently concentrated and free of cocontaminants to allow identification by infrared spectroscopy and gas chromatography/mass spectrometry.  相似文献

In this article, we examine gang membership and gang activity in Dona Ana County, New Mexico. We collected the data through a self-administered questionnaire completed by 373 randomly selected 9th and 11th grade students attending two high schools and two junior high schools. By the self-report method, 56 indicated they were currently active in a gang; another 45 had been members of gangs but were no longer involved; and, “wannabes,” or students who at some time had considered joining a gang but did not or could not, totaled 68. The 169 students who indicated some interest in or involvement with gangs represented 45% of the total sample. A more restrictive definition of actual gang membership (i.e., the group must have initiation rites and employ some external symbols of membership, such as “colors,” tattoos, or handsigns) results in a different trichotomization. We employ both the self-definition and restrictive definition of gang membership in our analysis of their personal biographical characteristics and criminal behavior. Our findings suggest that self-definition demonstrates clearer ties to self-reported gang-related activities than does the more restrictive one. We discuss the policy implications of this finding in the article.  相似文献

A new method has been optimised to amplify five X chromosome short tandem repeat (STR) markers of interest in forensic medicine: human phosphoribosyl transferase (HPRTB), DXS101, androgen receptor (ARA), DXS7423 and DXS8377. Markers were conveniently amplified in a single PCR reaction with fluorochrome-labelled primers, which allowed the analysis of fragment sizes after injection into a capillary electrophoresis system. The most common alleles of each locus were sequenced and used in a control ladder to type unknown samples.  相似文献
