The Collusion of Feminist and Postmodernist Impulses in E.L. Doctorow’s "Ragtime"

Many critics of Doctorow have classified him as a postmodernist writer, acknowledging that a wide number of thematic and stylistic features of his early fiction emanate from the postmodern context in which he took his first steps as a writer. Yet, these novels have an eminently social and ethical scope that may be best perceived in their intellectual engagement and support of feminist concerns. This is certainly the case of Doctorow’s fourth and most successful novel, Ragtime. The purpose of this paper will be two-fold. I will explore Ragtime’s indebtedness to postmodern aesthetics and themes, but also its feminist elements. Thus, on the one hand, I will focus on issues of uncertainty, indeterminacy of meaning, plurality and decentering of subjectivity; on the other hand, I will examine the novel’s attitude towards gender oppression, violence and objectification, its denunciation of hegemonic gender configurations and its voicing of certain feminist demands. This analysis will lead to an examination of the problematic collusion of the mostly white, male, patriarchal aesthetics of postmodernism and feminist politics in the novel. I will attempt to establish how these two traditionally conflicting modes coexist and interact in Ragtime.

Benthic assemblages associated with native and non-native oysters are similar

Invasive species can impact native species and alter assemblage structure, which affects associated ecosystem functioning. The pervasive Pacific oyster, Crassostrea gigas, has been shown to affect the diversity and composition of many host ecosystems. We tested for effects of the presence of the invasive C. gigas on native assemblages by comparing them directly to assemblages associated with the declining native European oyster, Ostrea edulis. The presence of both oyster species was manipulated in intertidal and subtidal habitats and reefs were constructed at horizontal and vertical orientation to the substratum. After 12 months, species diversity and benthic assemblage structure between assemblages with C. gigas and O. edulis were similar, but differed between habitats and orientation, suggesting that both oyster species were functionally similar in terms of biodiversity facilitation. These findings support evidence, that non-native species could play an important role in maintaining biodiversity in systems with declining populations of native species.

Diferenças no Funcionamento Emocional, Comportamental e Social (Roberts Apperception Test for Children) e na Autoestima (Rosenberg Self Esteem Scale) entre Jovens Institucionalizados e Não Institucionalizados

Objetivos: A institucionalização é, habitualmente, um momento gerador de sentimentos negativos, tais como a perda e o abandono, fragilizando os jovens envolvidos neste processo e, eventualmente, condicionando o seu funcionamento emocional, comportamental e social. O nosso estudo tem como objetivos: 1) verificar a existência de diferenças entre uma amostra de jovens institucionalizados e uma amostra de jovens não institucionalizados nas dimensões de um instrumento que avalia o funcionamento social, comportamental e emocional (Roberts Apperception Test for Children/RATC) e na autoestima (Rosenberg Self Esteem Scale/RSES); 2) explorar se existem diferenças entre as duas amostras ao nível de diferentes variáveis sociodemográficas, familiares e clínicas (e.g. história de sintomas depressivos em toda a vida e atual). Método: A amostra é composta por 60 jovens, 30 não institucionalizados (subamostra de controlo) e 30 institucionalizados (entre os 10 e os 15 anos de idade). A amostra de controlo respondeu a um questionário sociodemográfico e à Rosenberg Self Esteem Scale (RSES). Os jovens institucionalizados responderam a esta escala e a algumas perguntas do questionário sociodemográfico, tendo outras sido completadas com base nos processos da instituição. O autor administrou, junto das duas subamostras, o Roberts Apperception Test for Children (RATC). Resultados: Não foram encontradas diferenças estatisticamente significativas entre as duas amostras, no que diz respeito à RSES. Quanto ao RATC, foram encontradas diferenças estatisticamente significativas no que diz respeito apenas a quatro dimensões: Suporte aos outros, Identificação de problemas, Resolução 2 e Problema não resolvido. Verificaram-se associações significativas entre a pertença a uma ou outra subamostra e algumas variáveis sociodemográficas e clínicas, por exemplo, a escolaridade do pai e da mãe e a vivência de sintomatologia depressiva em toda a vida. Conclusões: No geral, o funcionamento emocional, social e comportamental, assim como a autoestima de jovens institucionalizados parece não se diferenciar grandemente dos de jovens não institucionalizados. Ainda assim, os jovens institucionalizados parecem apresentar resultados menos adaptativos em algumas dimensões, por comparação com os jovens institucionalizados.

The Effect of Mark Enhancement Techniques on the Subsequent Detection of Saliva

There appears to be a limited but growing body of research on the sequential analysis/treatment of multiple types of evidence. The development of an integrated forensic approach is necessary to maximise evidence recovery and to ensure that a particular treatment is not detrimental to other types of evidence. This study aims to assess the effect of latent and blood mark enhancement techniques (e.g. fluorescence, ninhydrin, acid violet 17, black iron-oxide powder suspension) on the subsequent detection of saliva. Saliva detection was performed by means of a presumptive test (Phadebas®) in addition to analysis by a rapid stain identification (RSID) kit test and confirmatory DNA testing. Additional variables included a saliva depletion series and a number of different substrates with varying porosities as well as different ageing periods. Examination and photography under white light and fluorescence was carried out prior to and after chemical enhancement All enhancement techniques (except Bluestar® Forensic Magnum luminol) employed in this study resulted in an improved visualisation of the saliva stains, although the inherent fluorescence of saliva was sometimes blocked after chemical treatment. The use of protein stains was, in general, detrimental to the detection of saliva. Positive results were less pronounced after the use of black iron-oxide powder suspension, cyanoacrylate fuming followed by BY40 and ninhydrin when compared to the respective positive controls. The application of Bluestar® Forensic Magnum luminol and black magnetic powder proved to be the least detrimental, with no significant difference between the test results and the positive controls. The use of non-destructive fluorescence examination provided good visualisation; however, only the first few marks in the depletion were observed. Of the samples selected for DNA analysis only depletion 1 samples contained sufficient DNA quantity for further processing using standard methodology. The 28 day delay between sample deposition and collection resulted in a 5-fold reduction in the amount of useable DNA. When sufficient DNA quantities were recovered, enhancement techniques did not have a detrimental effect on the ability to generate DNA profiles. This study aims to contribute to a strategy for maximising evidence recovery and efficiency for the detection of latent marks and saliva. The results demonstrate that most of the enhancement techniques employed in this study were not detrimental to the subsequent detection of saliva by means of presumptive, confirmative and DNA tests.
