    Le racisme a Ă©tĂ© un instrument essentiel du colonialisme europĂ©en. La prĂ©tention europĂ©enne Ă  la supĂ©rioritĂ© – fondĂ©e en partie sur la perception des rĂŽles de genre Ă  la fois dans les sociĂ©tĂ©s europĂ©ennes et dans les sociĂ©tĂ©s colonisĂ©es – a Ă©tĂ© nĂ©cessaire pour justifier l’exploitation coloniale. Des liaisons sexuelles entre des femmes colonisĂ©es et des EuropĂ©ens ont Ă©tĂ© utilisĂ©es Ă  la fois pour le profit commercial et pour exercer un contrĂŽle social. De maniĂšres variĂ©es, on a considĂ©rĂ© les enfants issus de ces liaisons comme des problĂšmes que les diffĂ©rentes puissances coloniales ont essayĂ© de rĂ©soudre par des moyens diffĂ©rents.Racism was an essential instrument of European imperialism. Europeans’ claim to superiority – based in part on perceptions of women’s gender roles in the societies of both imperialists and subjects – was necessary to justify imperial exploitation. Sexual liaisons between subject women and European men were used to promote commercial advantage and exercise various forms of social control. The children of these liaisons were considered, in various ways, a problem which different imperial powers attempted to resolve in different ways

    Transduction of fetal mice with a feline lentiviral vector induces liver tumors which exhibit an E2F activation signature

Copyright @ 2014 The American Society of Gene & Cell Therapy.Lentiviral vectors are widely used in basic research and clinical applications for gene transfer and long-term expression; however, safety issues have not yet been completely resolved. In this study, we characterized hepatocarcinomas that developed in mice 1 year after in utero administration of a feline-derived lentiviral vector. Mapped viral integration sites differed among tumors and did not coincide with the regions of chromosomal aberrations. Furthermore, gene expression profiling revealed that no known cancer-associated genes were deregulated in the vicinity of viral integrations. Nevertheless, five of the six tumors exhibited highly significant upregulation of E2F target genes, of which a majority are associated with oncogenesis, DNA damage response, and chromosomal instability. We further show in vivo and in vitro that E2F activation occurs early on following transduction of both fetal mice and cultured human hepatocytes. On the basis of the similarities in E2F target gene expression patterns among tumors and the lack of evidence implicating insertional mutagenesis, we propose that transduction of fetal mice with a feline lentiviral vector induces E2F-mediated major cellular processes that drive hepatocytes toward uncontrolled proliferation culminating in tumorigenesis.ISF, DFG, the Kamea Scientific Foundation, the European Research Council, the Lillyan & Alfy Nathan, Barbara Fox Miller, and Wolfson Foundations

    Eccentric Exercise Activates Novel Transcriptional Regulation of Hypertrophic Signaling Pathways Not Affected by Hormone Changes

    Unaccustomed eccentric exercise damages skeletal muscle tissue, activating mechanisms of recovery and remodeling that may be influenced by the female sex hormone 17ÎČ-estradiol (E2). Using high density oligonucleotide based microarrays, we screened for differences in mRNA expression caused by E2 and eccentric exercise. After random assignment to 8 days of either placebo (CON) or E2 (EXP), eighteen men performed 150 single-leg eccentric contractions. Muscle biopsies were collected at baseline (BL), following supplementation (PS), +3 hours (3H) and +48 hours (48H) after exercise. Serum E2 concentrations increased significantly with supplementation (P<0.001) but did not affect microarray results. Exercise led to early transcriptional changes in striated muscle activator of Rho signaling (STARS), Rho family GTPase 3 (RND3), mitogen activated protein kinase (MAPK) regulation and the downstream transcription factor FOS. Targeted RT-PCR analysis identified concurrent induction of negative regulators of calcineurin signaling RCAN (P<0.001) and HMOX1 (P = 0.009). Protein contents were elevated for RND3 at 3H (P = 0.02) and FOS at 48H (P<0.05). These findings indicate that early RhoA and NFAT signaling and regulation are altered following exercise for muscle remodeling and repair, but are not affected by E2

    The legacies of coercion and the challenges of contingency: Mozambican unions in difficult times

    Although insecure work may be found everywhere, the general lack of secure work in emerging economies is a particularly striking feature of the contemporary condition, undermining the continued viability of the labour movement in such countries. Yet, this topic is rarely tackled directly in African studies or business history journals. The two key questions addressed in this paper are, first, to what extent does the labour movement’s past define their present and future, and second, what are the challenges and opportunities affecting their ability to mobilise workers, influence government and effectively tackle employment security? This article details how in Mozambique, unions’ ability to mobilise has been affected by: the post-colonial, post-conflict and post-socialist historical context; the resulting legacies of regional and racial discrimination; international imperatives for liberalisation and privatisation; challenging relationships with the country’s African neighbours; and high levels of informal sector work. In order to remain viable, key imperatives include: effectively influencing national government, engaging internationally and working with organisations representing informal sector workers

    How Does Institutional Change Coincide with Changes in the Quality of Life? An Exemplary Case Study

    Full text link
    This paper provides a framework to assess correlations between the change of institutional functions (political centralization, plurality, rule of law, security of property, economic liberty, measured by 12 indicators) and improvements in human development (income, education, health) and violence limitations (conflict-related death tolls) to separate effective from ineffective institutional change. We apply this framework to a low-end institutional environment and provide a century case study of todays Democratic Republic of the Congo (DRC). Major results are threefold: first, we provide a thick description of institutional development in the Congo in a colonial and post-colonial and hence long-run setting; secondly, we identify periods of institutional change with distinctly different degrees of effectiveness; and thirdly, we are able to provide qualitative information on the questions of perspective (we follow a non-elitist approach), institutional connections, and timing of effects. Finally we propose extension of the framework, especially with respect to in-depth studies of critical transition periods, and its application to comparative case studies
