Arab Islamic oppositions have proven largely ineffectual in molding regime outcomes since the liberalizations of the 1980s and 1990s, although many continue to overestimate their potential for propelling reform. This article argues that a keen sense of the past is necessary when evaluating whether or not an opposition matters for political reform. Section I introduces noted scholar Juan Linz's notion of “semi‐opposition”—limited and “semi‐free” opposition groups that may sustain authoritarian regimes as much as repression. Using interviews and English and Arabic sources, Section II demonstrates historical correspondences between semi‐opposition and the Jordanian and Egyptian Muslim Brotherhood (MB) organizations concerning origins and support, ideology and approach to politics, regime tolerance and political environment, and political behavior. Section III develops Linz's hypothesis on the links between semi‐opposition and authoritarian persistence by examining how the MB marginalizes and raises the costs of dissent for other opposition groups and actors. The MB is briefly contrasted with the Algerian Front Islamique du Salut (FIS) opposition party of 1989–1992 in Section IV . Decidedly not a semi‐opposition, the FIS proved far more transformative than either the Jordanian or Egyptian MB, inducing centrifugal politics and the collapse of the Front de Libération Nationale (FLN) state that governed Algeria from 1962.  相似文献

Analytical investigations through phytochemical screening, scanning electron microscope (SEM) and light microscopic observation of the earthen plaster of Karla Caves of western India identified the presence of antifungal, antibacterial and insect repellent Careya arborea stem fibres as a vegetal additive. The scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDX) study also revealed the inclusion of rice (Oryza sativa) husk as a plant additive in the plaster. In the high rain-fed coastal regions of western India, the antimicrobial, antioxidant and termite-resistance properties of C. arborea helped the survival of the plaster in unfavourable climatic conditions. Besides, the C. arborea and rice husk together played a role in reducing cracks, decreasing the density, and imparting a plasticity and a durability to the plaster. The liquid Fourier-transform infrared spectrometer (FTIR) of organic extracts revealed carboxylic acid (fatty acids)-based additives in the earthen plaster. From the gas chromatography-mass spectrometry (GC-MS) analysis of the plaster, the presence of animal milk fat, animal and vegetable fat, and vegetable oil was identified, and probably used to strengthen the earthen plaster for their resistance to tensile stress. The analysis also diagnoses the inclusion of methyl commate B, a resinous material obtained from the Burseraceae plant family, which has antimicrobial properties, through GC-MS analysis.  相似文献

Abstract

We reflect on our relationship to the Feminist Freedom Warriors (FFW) online archive of transnational scholar-activist genealogies. From our respective locations at a PWI and an HBCU, we explore what it might mean to conceive of these new media narratives as archives of mentorship. For us, the archive is a significant resource of useful feminism–those modes of feminist thought, action, and history that meet our mentorship needs, stitching together practices of self-mentorship and co-mentorship. Our engagement with the narratives sharpen an understanding of how intertwined structures of gender, race, sexuality, caste and class operate at both the local and global level, and are facilitated by and through US academia. Moreover, the larger constellation of FFW inspire our own practice of ‘queer of color feminist co-mentorship’. We generate a collaborative analysis detailing our expanding perspectives on identity, difference, and the US graduate school experience. Our collective journey informs us that innovative conceptions and practices of feminist mentorship can radically challenge and enhance traditional mentorship, creating novel possibilities for learning and connection.  相似文献

Abstract

This paper uses a framework of ‘ontological security’ to discuss the psychosocial strategies of self-securitisation employed by ethnic and religious minority young people in Scotland. We argue that broad discourses of securitisation are present in the everyday risks and threats that young people encounter. In response and as resistance young people employ pre-emptive and pro-active strategies to preserve ontological security. Yet, these strategies are fraught with ambivalence and contradiction as young people withdraw from social worlds or revert to essentialist positions when negotiating complex fears and anxieties. Drawing on feminist geographies of security the paper presents a multi-scalar empirical analysis of young people’s everyday securities, connecting debates on youth and intimacy-geopolitics with the social and cultural geographies of young people, specifically work that focuses upon young people’s negotiations of racialised, gendered and religious landscapes.  相似文献
