The exploration and examination of the construction of masculinity is increasingly emerging as an integrated part of the study of gender in society in general, and in the Caribbean in particular. We are constantly in search for new sources of material which tell us about the ways in which men construct their masculinity in Caribbean society. In this paper I draw on the imagery and ideas provided by the literary text. I interrogate the novel The Dragon Can't Dance, written by Trinidadian novelist Earl Lovelace. The writer uses the metaphor of the dragon, the costume donned by the main protagonist Aldrick in the yearly Carnival masquerade, as a mask which disguises the need for Aldrick to confront his own masculinity under poor, urban conditions in Trinidad. In the struggles and confrontations between urban working-class men and women in the community of Calvary in Trinidad, the novelist teases out the different constructions of masculinity in the various characters he portrays. I explore the novel, focusing particularly on the ways in which this construction is embedded in the struggles over issues of identity, ethnicity, reputation and honor. While the novelist is clearly able to read into the mind of the male in society, his renditions of the female are not so incisive. However, this is not a shortcoming as the women, though not as well-rounded characters in the novel, play key roles in the definition and shaping of masculinities. This reading of the novel illustrates that the literary text suggests itself as a critical site for further explorations of the illusive data on gender and especially that on masculinity.  相似文献

The effect of the shape of semiconductor nanocrystals on their performance for visualising latent fingermarks was investigated for the first time. Highly luminescent CdSe/CdS core/shell nanocrystals in rod and spherical shapes were synthesised in organic solvent and transferred to aqueous solution using ligand exchange. The 3-mercaptopropionic acid coated nanorods and nanospheres were characterised using electron microscopy and UV-visible absorbance and luminescence spectrophotometry. A simple and rapid development of fresh to less than a week-old natural fingermarks from 4 donors (male and female) on non-porous surfaces including glass slides, aluminium foil and germanium disks using both CdSe/CdS core/shell nanorods and spherical dots was achieved, wherein nanorods demonstrated an enhanced development of ridge details in comparison to the spherical dots.  相似文献

Condom residues may be encountered in forensic investigations as traces in sexual assault or rape cases. Casework studies have shown the value of distinguishing condom residues from other types of personal products used by women. However, up to now, there has been no investigation of their chemical variability within an international context. This work employed attenuated total reflectance Fourier transform infrared spectroscopy with chemometrics to provide objective characterisation of condom lubricants and personal hygiene products from the international market. 166 samples were obtained covering five major classes of products likely to be used by women. Principal component analysis distinguished most major classes based on their spectral profiles, with subsequent support vector machine models yielding discrimination accuracies over 90%. A two-step approach was subsequently developed and enabled both classification and a discrimination accuracy of 100%. This could provide greater confidence in chemical discrimination of residues from these products when conducting investigations and help assess the origin of the chemical profile obtained. Further testing using three validation sets produced an identification accuracy of 100% for generic classes, which may allow investigative leads to be more readily obtained from recovered evidence.  相似文献

Did the bombing of the federal building in Oklahoma City affect the public's perception of terrorism as a political issue and their perceptions of individual risk and personal vulnerability? The author finds that the bombing in Oklahoma City altered neither the public's assessment of personal risk nor its reported behavior. Public opinion on terrorism and crime share three patterns: (1) perceived risk of victimization and the likely consequences affect public apprehension; (2) the voiced sense of personal security bears a direct relationship to the relative familiarity of the setting; and (3) the public shows resistance to the media's portrayal of risk. Opinion data indicate that domestic terrorism is likely to be seen as important in general and in the abstract, but with low personal risk, little impact on individuals' routine behavior, and, consequently, low political salience. In light of terrorism's purpose of inducing fear and the public's generally placid response on a personal level, the author concludes that the bombing failed as an act of domestic terrorism.  相似文献

Ongoing work at the U.S. National Institute of Standards and Technology has focused on the characterization of 26 autosomal STR loci for human identity testing. These 26 loci are in addition to the existing 13 U.S. core loci and those found in PowerPlex16 and Identifiler commercial STR typing kits. The amplification of the 26 loci has been optimized for degraded extracts in unique miniplex panels and also for reference samples as a single reaction 26plex assay. A study has been performed comparing genotypes obtained with the 26plex primers to those with miniplex panels for allele drop out and concordance. The forensic utility of the 26plex assay was evaluated for situations where additional loci are beneficial. The utility of this large multiplex was also tested in a case involving DNA extracted from degraded bone samples. The 26plex can serve as a low-cost assay (compared to commercially available kits) useful for both sorting comingled remains and providing additional markers for increased statistical support for samples that require “non-trio” family references for human identification.  相似文献

Protests in Africa have a long history. Yet, for many years, western misconceptions in protest studies have hindered our understanding of the particularities and commonalities of African protests. In this study, we scrutinize the historical continuity and discontinuity of protests in Africa, using Ghana as a case. We situate a longitudinal analysis of protests in Ghana within the theoretical model of protest logics, using the institutional-analytical method. The study finds historical continuity largely in terms of proletarian (high cost of living, dispossession and inadequate infrastructure), republican (participatory governance and corruption) and corporatist (working conditions and unemployment) mobilisation themes in Ghana. These themes are underpinned by the processes of class struggle, accumulation by (urban) dispossession, neoliberalism, splintered urbanism, gentrification and corruption. The implication of this study is that contemporary protests in Africa would be influenced by issues such as high cost of living, participatory governance, erratic power supply, unemployment, poor road infrastructure and corruption. These issues should be prioritized in the agenda of African governments in order to avert spontaneous protests.  相似文献

Active research on a wide range of political contexts centers on ethnicity's role in collective action. Many theories posit that information flows more easily in ethnically homogeneous areas, facilitating collective action, because social networks among coethnics are denser. Although this characterization is ubiquitous, little empirical work assesses it. Through a novel field experiment in a matched pair of villages in rural Uganda, this article directly examines word‐of‐mouth information spread and its relationship to ethnic diversity and networks. As expected, information spread more widely in the homogeneous village. However, unexpectedly, the more diverse village's network is significantly denser. Using unusually detailed network data, we offer an explanation for why network density may hamper information dissemination in heterogeneous areas, showing why even slight hesitation to share information with people from other groups can have large aggregate effects.  相似文献

Why do local officials in an authoritarian bureaucracy experiment with policy, even when directed not to do so by central‐level officials? This study suggests that policy experimentation in this institutional environment can best be understood as an interaction between the structure in which local officials are embedded and individual‐level personality attributes. Leveraging a new data set from a series of original surveys with local policy makers in mainland China, conducted between 2016 and 2018, we discern three baseline personality types: authoritarian, consultative, and entrepreneurial. We thereafter examine the individual‐level characteristics of local officials who will innovate irrespective of a centralization of bureaucratic power and interests, as currently experienced under Chinese President Xi Jinping. We find that local policy makers engage in policy innovation when they are more focused on resolving governance problems and that increased risk reduces but does not eliminate their willingness to innovate. Based on these findings, we contend that future studies of policy innovation should use an evolutionary framework to examine the interaction between preferences and selection pressures.  相似文献
