Abstract

Focusing on recent debates over the ways in which subaltern groups engage with the state in India, the article proposes that it is imperative to historicise our conceptions of subaltern politics in India. More specifically, the argument is made that it is imperative to recognise that subaltern appropriations of the institutions and discourses of the state have a longer historical lineage than what is often proposed in critical work on popular resistance in rural India. The article presents a detailed analysis of Adivasi rebellions in colonial western India and argues that these took the form of a contentious negotiation of the incorporation of tribal communities into an emergent “colonial state space.” The conclusion presents a sketch of a Gramscian approach to the study of how subaltern politics proceeds in and through determinate state–society relations.  相似文献

A number of N‐substituted piperazines have been described as drugs of abuse in recent years. This new drug category includes several series of aromatic ring substituted phenylpiperazines. The wide variety of available precursors makes regioisomerism a significant issue in these totally synthetic compounds. In this study, a complete series of regioisomeric dimethoxyphenylpiperazines were synthesized and evaluated using GC‐MS and FT‐IR. The EI mass spectra show fragments characteristic of both the dimethoxyphenyl and the piperazine portions of the molecules including the dimethoxyphenylaziridinium cation (m/z 180) and dimethoxyphenyl cation (m/z 137). The ion at m/z 56 for the C3H6N+ fragment is characteristic of the piperazine ring and was observed in all the spectra. The perfluoroacyl derivatives were resolved by GC, and their mass spectra showed some differences in relative abundance of ions. FTIR provides direct confirmatory data for differentiation between the regioisomeric dimethoxyphenylpiperazines, and GC separation was accomplished on an Rtx‐200 phase.  相似文献

Identification of osseous materials is generally established on gross anatomical features. However, highly fragmented or taphonomically altered materials may be problematic and may require chemical analysis. This research was designed to assess the use of scanning electron microscopy–energy-dispersive X-ray spectrometry (SEM/EDX), elemental analysis, and multivariate statistical analysis (principal component analysis) for discrimination of osseous and nonosseous materials of similar chemical composition. Sixty samples consisting of osseous (human and nonhuman bone and dental) and non-osseous samples were assessed. After outliers were removed a high overall correct classification of 97.97% was achieved, with 99.86% correct classification for osseous materials. In addition, a blind study was conducted using 20 samples to assess the applicability for using this method to classify unknown materials. All of the blind study samples were correctly classified resulting in 100% correct classification, further demonstrating the efficiency of SEM/EDX and statistical analysis for differentiation of osseous and nonosseous materials.  相似文献

超高效液相色谱-MS/MS法测定血中11种苯丙胺类物质   总被引:1,自引:1,他引:0  
目的应用超高效液相色谱-质谱法对全血中11种苯丙胺类毒品进行定量测定。方法全血样品经1%(v/v)甲酸-乙腈提取,采用Ostra磷脂过滤板净化处理,使用ACQUITY UPLC BEH Phenyl(100mm×2.1mm,1.7μm)色谱柱,以0.3%(v/v)甲酸溶液-乙腈为流动相进行梯度洗脱。在多反应监测模式下测定全血样本中苯丙胺、甲基苯丙胺、二亚甲基双氧苯丙胺、替苯丙胺、3,4-亚甲基二氧基乙基苯丙胺、N-甲基-1-(3,4-亚甲二氧基苯基)-2-丁胺、副甲氧基甲基苯丙胺、麻黄碱、甲基麻黄碱、卡西酮、甲卡西酮,并进行方法学考察。结果 11种苯丙胺类物质的检出限(S/N≥3)为0.01~0.4ng/m L,在0.5~50μg/L范围内线性关系良好(r0.999);回收率在75.8%~103.4%之间,相对标准偏差在1.6%~13.0%之间。结论本文建立的超高效液相色谱-质谱法快速、简便、灵敏,适用于中毒案件检验及吸毒人员排查。  相似文献

目的探讨硫化氢(H2S)中毒者血中H2S的检测及特征鉴别;方法取新鲜空白血液和5℃下保存1月、1年的血液各2m L,经微波低火加热1min后,吸取顶空气体100μL进行GC/PFPD-S、GC/MS检测;取相同样本进行酸化处理后进行检测;取疑似为H2S中毒者血液直接加热后进行检测。结果新鲜血液和5℃下保存1月、1年的血液均可检出H2S成分,但保存1个月以上的血液可同时检出二硫化碳(CS2)成分;酸化处理后的血液,H2S和CS2成分检出的含量明显比未加酸化的血液高;中毒者血液中除了检出H2S成分外,还检出甲硫醚成分。结论血液样本同时检出H2S和较大量的CS2时,不宜判定为H2S中毒,提示可能为腐败所致,而同时检出H2S和较大量的甲硫醚,则可做出H2S中毒的判断。  相似文献

This article argues that we should take more seriously the role of intermediaries in relationships between states and citizens in the global south. More specifically it holds that the practice of mediation, the third party representation of citizens to states and vice versa, is a widespread and important political practice in this context. Largely distinct from the contentious politics and popular mobilisation of social movements, mediation is more a politics of negotiation and bargaining by representatives. Developed as an emergent analysis from multiple case studies, mediation is a broad concept that includes practices that at other times might be described as lobbying, clientelism and coercion, but that we conceptualise in terms of claiming legitimacy to speak for the poor and marginalised, and theorise in terms of a democratic deficit between formal political institutions and these groups. In addition to identifying different kinds of mediators, the article categorises mediation in terms of the orientation and nature of various mediatory practices. Lastly, the article identifies at least three explanations for mediation including the endurance of pre-democratic political relations and practices, new forms of social exclusion in post-colonial democracies and the erosion of state authority brought about by neo-liberal policies and globalisation.  相似文献

Taking its point of departure in how specific regional organizations function and interact in the Mediterranean, this article attempts to show to what degree this institutional setup has influenced the developments in the Arab Mediterranean states after the Arab revolts. The analysis of the organizational and institutional setup in the Mediterranean is theoretically founded in the new institutionalism tradition. Furthermore, a regionalism perspective is applied, touching on discussions related to European normative ambitions. It is demonstrated that the regional organizations only to a limited degree have contributed to democratization processes or to democratic consolidation in a post–Arab Spring context, and it is argued that it seems unlikely that these organizations in the future will develop into tools for democratization in the Mediterranean region.  相似文献

This article aims to trace South–South cooperation political lineages connecting the Non-Aligned Movement and the IBSA (India, Brazil, South Africa) Forum. In order to determine whether IBSA could be considered the ‘heir’ to Bandung's principles, we analyse the concepts of ‘Third World’ and ‘Global South’ as well as their current applicability, the interpretations provided by existing literature on the IBSA grouping, and its member countries' shared views on different issues of the international agenda. The article also considers the historical evolution of ‘Southern’ diplomatic thought and actions. IBSA's actions and history, as well as its members, are studied to grasp how they are related to the Third World movement in the Cold War.  相似文献

Through an analysis of the relations between the state and the media in Burundi, this article aims to problematise these actors’ interactions within a context characterised by an asymmetry of power in favour of political authorities and some leeway enjoyed by the media. Through a review of a corpus constituted of scientific literature, reports documenting the situation of press freedom in the country, and newspaper articles, the present article shows that the legal framework governing media activity is rather protective of press freedom, despite some recent setbacks. Under this protective media context, the state uses a variety of devious means to strengthen its grip on the media sector and on journalists. The media, for their part, are obliged to manoeuvre in a post-traumatic context where issues of security have a strong public legitimacy. The article shows that in order to understand relations between the Burundian state and the media, it is necessary to place them in an asymmetrical power context where both face constraints and enjoy spaces of tactical intervention.  相似文献
