Considered superficially, the women in the Torquemada novels conform to the negative gender stereotypes imposed upon them by their male counterparts. On further examination, however, we discover that the male viewpoints are both undermined and questioned, and a number of female characters are used to pose questions that are even more ambitious than those raised in Galdosian novels where the eponymous characters are women. Aiming to enhance our understanding of the significance of the female characters in Galdós’s novels, as well as unearthing their complexity, this article highlights the presence of ambiguity in the Torquemada novels and argues that these works question traditional perceptions of women. Boundaries are revealed to be hazy and the male characters (who sometimes have effeminate qualities) are essentially puppets or “fronts” in what is effectively a domain controlled by the women. Displaying a level of resourcefulness, creativity, and resilience that surpasses that of their male counterparts, the female characters (particularly Cruz) are sometimes influential catalysts for change. Hence, rather than being misconstrued as “a problem” or “al borde de un naufragio,” they could be regarded as potential redeemers in a Spain that was in need of regeneration.  相似文献

When Abusive Head Trauma (AHT) is suspected in a child, a dilated eye examination by an ophthalmologist is an essential part of the medical workup, as the presence and pattern of retinal hemorrhages can have a high positive predictive rate for abusive head injury. This article proposes to review the clinical presentation, pathophysiology, natural history, sequelae, and differential diagnosis of retinal hemorrhages and other ocular lesions associated with AHT.  相似文献

Abstract

In Stevie Smith's debut novel Novel on Yellow Paper, set in 1936, the narrator Pompey Casmilus recalls several trips to Germany she made in the years shortly before the rise of the Hitler regime. The memories of these German travels are linked to Pompey's love affair with a Swiss-German student named Karl with whom she has spent time in both England and Germany. The essay explores the significance of the German theme in the novel. This theme emerges in Pompey's memories of Germany and Karl, which at first glance appear to be random moments of recollection. However, the German theme also asserts itself in what I call Pompey's German voice, a distinct narrative voice that uses a specific German vocabulary and mimics German speech patterns, which appears at different points throughout the novel and is not exclusively linked to Pompey's memories of Germany. The essay argues that this narrative voice, the Karl-Pompey romance plot and the narrator's obsessive concern with Jewishness combine into an exploration of the Anglo-German relationship in the inter-war years and the attraction which Germany held for some British visitors during the 1920s and early 1930s, an attraction which is linked to previous literary explorations of the country by British writers such as D. H. Lawrence and which by 1936 has taken on an ominous significance as Pompey observes from afar the atrocities being committed within Germany in the name of the Hitler regime.  相似文献

This article examines the post‐war dismantling of the Special Operations Executive (SOE) and amalgamation with the Secret Intelligence Service (SIS). It is argued that the existing literature has been unclear on this matter, confusing two very different SIS departments, the Special Operations Branch and the Special Political Action Section. The article then examines how the assets and personnel of SOE were dispersed to three different divisions of the SIS; the Directorates of Production, Training and Development and War Planning, and then examines the separate origins and function of the Special Political Action Section.  相似文献

This article argues that there is an inherent tension in legislative intelligence oversight bodies between their responsibility to the voters who elect them and their political parties who select them to run for office. At a time of acute political crisis, the partisan interests of the legislators who sit on oversight bodies may override their other responsibilities. This can result in distorted and misleading investigations and reports. This hypothesis is examined against the evidence of precisely such a mode of failure in both the British and American legislative inquiries into intelligence on Iraqi ‘weapons of mass destruction’. The authors conclude that any effective oversight must include a range of parallel legislative, judicial, executive and independent mechanisms to try and minimize the inherent weaknesses in each oversight model.  相似文献

Indian snakeroot (Rauvolfia serpentina) is a valuable forest product, root extracts of which are used as an antihypertensive drug. Increasing demand led to overharvesting in the wild. Control of international trade is hampered by the inability to identify root samples to the species level. We therefore evaluated the potential of molecular identification by searching for species‐specific DNA polymorphisms. We found two species‐specific indels in the rps16 intron region for R. serpentina. Our DNA barcoding method was tested for its specificity, reproducibility, sensitivity and stability. We included samples of various tissues and ages, which had been treated differently for preservation. DNA extractions were tested in a range of amplification settings and dilutions. Species‐specific rps16 intron sequences were obtained from 79 herbarium accessions and one confiscated root, encompassing 39 different species. Our results demonstrate that molecular analysis provides new perspectives for forensic identification of Indian snakeroot.  相似文献
