This article discusses the representation of gender and nationality in the historical fiction of Hilda Vaughan, a Welsh woman writing in English during the early twentieth century. It offers a detailed discussion of her second novel, Here are Lovers (1926), but also makes reference to other texts. These texts are located within the historical context of the interwar period when nationality was a key issue for both feminist campaigners and emerging Welsh nationalist politics. The article draws upon the theoretical work of Williams and Foucault and argues that Vaughan's fiction offers a particularly sustained exploration of the gendering and classing of national identity.  相似文献

Ammonium nitrate fuel oil is an explosive mixture found in most antipersonnel landmines (APL) buried throughout the Colombian territory. During more than 50 years of internal conflict, the Colombian government has found that trained dogs are the most effective method to detect APL. However, the olfactive signature in ANFO is unknown and also if there are differences in detection related to the explosive manufacturing origin. Therefore, this work begins with the analytical validation of the method used to determine ammonia, in its derivatized form as carbamate, released by home-made ANFO using HS-SPME-GC-FID. Once validated, the method was used to identify ammonia and other organic volatile compounds present in ANFO, under laboratory and simulated field conditions. The validation process includes the evaluation of the optimum conditions for the derivation and extraction of butylcarbamate, the determination of the working ranges with linear response in FID, the limits of detection and quantification, the sensitivity, and the precision. The results of the validation established linearity and sensitivity in a concentration between 20 and 120 mg/L, as well as low limits of detection and quantification of 6.4 and 21.4 mg/L, respectively. Also, an intermediate precision of 11% for butylcarbamate with a repeatability of 8%. The validated method showed in real samples of home-made ANFO besides ammonia, the presence of low molecular methylamines, and also exhibited differences in volatile compositions according to the origin. The objective of this work is to offer a reliable analytical methodology for the extraction and analysis of volatile compounds from ANFO.  相似文献

The Olsonian distinction between roving and stationary bandits outlines the rationale behind the transition from anarchy to the emergence of the predatory state. This two-bandit model may, however, be expanded to include more bandit types. In the case of Viking Age England, local English kings were unable to monopolize violence and defend their realms against competing Viking raiders. As the Vikings’ time horizon grew, so did the accumulated value of more formal taxation, and bandit types evolved in four steps. The first step is the Olsonian roving bandit, who executed Viking hit-and-run attacks and plunders during the second half of the tenth century. The second step is the gafol bandit; gafol is payment for leaving, paid to, among others, Swein Forkbeard. The third step is the heregeld bandit; heregeld is a tax to support an army for hire; most notably Thorkell the Tall’s. The fourth step is the Olsonian stationary bandit, i.e. the strongest military leader among the Vikings, Cnut the Great, settled down as the new king. Overall, the Olsonian two-bandit model can be expanded to a four-bandit staircase model, in which the new gafol and heregeld bandit types explain the steps from anarchy and short-run raiding to long-run formal taxation in a predatory state.

The review essay takes stock of the last decade of decentralisation and regionalisation research in Central and South Eastern Europe. Classifying the existing scholarship with regard to its focus of analysis, its explanatory programme, and methodological predilections, we suggest to distinguish three different agendas: system transformation, EU conditionality and subnational governance. We argue that scholarly interest in regionalisation and decentralisation issues from the perspective of state transformation or Europeanisation is vanishing. Instead, we witness the emergence of a subnational governance approach which is rooted in comparative politics and policy analysis. The debate about decentralisation and regionalisation in CEEC is thus in a process of “normalising” and converging with the Western European subnational political discourse.  相似文献

In this article my principal aims are to explain why the concept of social capital has proven so popular among policy makers and to develop a critical response to it. In order to do so I bring together macro- and micro-level analyses that focus, on the one hand, on broad structural changes associated with globalisation and, on the other, on specific attempts at increasing social capital within the everyday lives of communities. To develop my macro-level analysis I suggest that the conjunction of economic volatility and demographic mobility that has affected the West since the 1970s has made building social capital an attractive option within a more general experiment with new forms of power. My claim here is that building social capital is among a clutch of recent policy initiatives designed to repair the ideological resources of contemporary liberal states, where it is the tearing as well as the weakening of the social fabric that is at stake. I focus on the British case because building social capital has been explicitly highlighted by the UK government as a vehicle for civic renewal. The micro-analysis proceeds by analysing recent surveys and policies undertaken by Camden Council. Micro refers here to local symptoms of global change; to the micro-powers being developed in response and to the local authorities where social capital policies are being operationalised. I associate these with biopolitical and ideological interventions into the very building blocks of the social. Overall, the genealogy of social capital explores how the concept's discursive significance has shifted as it moves from the democratisation literature into the policy arena and becomes entangled in relations of power. In the latter context it examines the impact of concerns about segregation that justify intrusive policies associated with social capital building.  相似文献

There is limited research that has examined experimentally the effects of muscular images on adolescent boys’ body image, with no research specifically examining the effects of music television. The aim of the current study was to examine the effects of viewing muscular and attractive singers in music video clips on early, mid, and late adolescent boys’ body image, mood, and schema activation. Participants were 180 boys in grade 7 (mean age = 12.73 years), grade 9 (mean age = 14.40 years) or grade 11 (mean age = 16.15 years) who completed pre- and post-test measures of mood and body satisfaction after viewing music videos containing male singers of muscular or average appearance. They also completed measures of schema activation and social comparison after viewing the clips. The results showed that the boys who viewed the muscular clips reported poorer upper body satisfaction, lower appearance satisfaction, lower happiness, and more depressive feelings compared to boys who viewed the clips depicting singers of average appearance. There was no evidence of increased appearance schema activation but the boys who viewed the muscular clips did report higher levels of social comparison to the singers. The results suggest that music video clips are a powerful form of media in conveying information about the male ideal body shape and that negative effects are found in boys as young as 12 years.  相似文献

The aim of the present study was to examine a model positing that association with deviant peers mediates the relation between adolescent perceived parenting behaviors (maternal monitoring and involvement), the interaction of these parenting behaviors, and delinquency in a sample of 135 urban African American adolescents (13–19 years of age). Regression analyses revealed a monitoring by involvement interaction among African American females, suggesting that maternal monitoring may effectively reduce delinquency among African American female adolescents, and that this reduction may be enhanced by increased maternal involvement. Among African American males, only the relation between association with deviant peers and delinquency was supported, suggesting that maternal parenting behaviors may, in isolation, be insufficient in the prevention of delinquent behaviors in African American male adolescents. The results suggest that the pathways from parenting to association with deviant peers and delinquency may differ in males and females, and the salience of certain parenting behaviors may differ across gender.
