Defending the 'Negro Race': Lamine Senghor and Black Internationalism in Interwar France

This article examines the career of Lamine Senghor, a Senegalese veteran of the First World War, who emerged in the mid 1920s as the most influential black anti-colonial activist of the period. Senghor combined a communist-inspired critique of empire with an attempt to forge a transnational sense of black identity. Many of the questions facing Senghor remain relevant today: should the black community seek equality through its own independent pressure groups or through strategic alliances with mainstream political parties? And how does one engage with issues of racial (or religious) equality within the terms of the purportedly colour-blind and secular Republic

Genome wide linkage study, using a 250K SNP map, of Plasmodium falciparum infection and mild malaria attack in a Senegalese population

Multiple factors are involved in the variability of host's response to P. falciparum infection, like the intensity and seasonality of malaria transmission, the virulence of parasite and host characteristics like age or genetic make-up. Although admitted nowadays, the involvement of host genetic factors remains unclear. Discordant results exist, even concerning the best-known malaria resistance genes that determine the structure or function of red blood cells. Here we report on a genomewide linkage and association study for P. falciparum infection intensity and mild malaria attack among a Senegalese population of children and young adults from 2 to 18 years old. A high density single nucleotide polymorphisms (SNP) genome scan (Affimetrix GeneChip Human Mapping 250K-nsp) was performed for 626 individuals: i.e. 249 parents and 377 children out of the 504 ones included in the follow-up. The population belongs to a unique ethnic group and was closely followed-up during 3 years. Genome-wide linkage analyses were performed on four clinical and parasitological phenotypes and association analyses using the family based association tests (FBAT) method were carried out in regions previously linked to malaria phenotypes in literature and in the regions for which we identified a linkage peak. Analyses revealed three strongly suggestive evidences for linkage: between mild malaria attack and both the 6p25.1 and the 12q22 regions (empirical p-value = 5 x 10(-5) and 96 x 10(-5) respectively), and between the 20p11q11 region and the prevalence of parasite density in asymptomatic children (empirical p-value = 1.5 x 10(-4)). Family based association analysis pointed out one significant association between the intensity of plasmodial infection and a polymorphism located in ARHGAP26 gene in the 5q31-q33 region (p-value = 3.7 x 10(-5)). This study identified three candidate regions, two of them containing genes that could point out new pathways implicated in the response to malaria infection. Furthermore, we detected one gene associated with malaria infection in the 5q31-q33 region

First Detection of Leishmania major DNA in Sergentomyia (Spelaeomyia) darlingi from Cutaneous Leishmaniasis Foci in Mali

Leishmania major complex is the main causative agent of zoonotic cutaneous leishmaniasis (ZCL) in the Old World. Phlebotomus papatasi and Phlebotomus duboscqi are recognized vectors of L. major complex in Northern and Southern Sahara, respectively. In Mali, ZCL due to L. major is an emerging public health problem, with several cases reported from different parts of the country. The main objective of the present study was to identify the vectors of Leishmania major in the Bandiagara area, in Mali. Methodology/Principal Findings: An entomological survey was carried out in the ZCL foci of Bandiagara area. Sandflies were collected using CDC miniature light traps and sticky papers. In the field, live female Phlebotomine sandflies were identified and examined for the presence of promastigotes. The remaining sandflies were identified morphologically and tested for Leishmania by PCR in the ITS2 gene. The source of blood meal of the engorged females was determined using the cyt-b sequence. Out of the 3,259 collected sandflies, 1,324 were identified morphologically, and consisted of 20 species, of which four belonged to the genus Phlebotomus and 16 to the genus Sergentomyia. Leishmania major DNA was detected by PCR in 7 of the 446 females (1.6%), specifically 2 out of 115 Phlebotomus duboscqi specimens, and 5 from 198 Sergentomyia darlingi specimens. Human DNA was detected in one blood-fed female S. darlingi positive for L. major DNA. Conclusion: Our data suggest the possible involvement of P. duboscqi and potentially S. darlingi in the transmission of ZCL in Mali

Race and the Legacy of the First World War in French Anti-Colonial Politics of the 1920s

There has been relatively little historical research on the small number of African veterans who stayed on in France after the First World War and became militants in the radical anti-colonial movements created in the 1920s. From his entry onto the political stage in late 1924 until his early death three years later, the most celebrated and feared of these anti-colonial militants was Lamine Senghor, a decorated war veteran from Senegal. This chapter will chart Senghor’s brief career as an activist, focusing primarily on the ways in which he projected his identity as a veteran in his speeches and writings, as well as exploring, more generally, how France’s “blood debt” to its colonial subjects became a key theme of anti-colonial discourse in the interwar period

Rhythm Returns: Movement and Cultural Theory

This introduction charts several of rhythm's various returns as a way of laying out the theoretical and methodological field in which the articles of this special issue find their place. While Henri Lefebvre’s rhythmanalysis is perhaps familiar to many, rhythm has appeared in a wide repertoire of guises, in many disciplines over the decades and indeed the centuries. This introduction attends to the particular roles of rhythm in the formation of modernity ranging from the processes of industrialization and the proliferation of new media technologies to film and literary aesthetics as well as conceptualizations of human psychology, social behaviour and physiology. These are some of the historical antecedents to the contemporary understandings of rhythm within body studies to which most of the contributions to this issue are devoted. In this respect, the introduction outlines recent approaches to rhythm as vibration, a force of the virtual, and an intensive excess outside consciousness

Student politics, teaching politics, black politics: an interview with Ansel Wong

Ansel Wong is the quiet man of British black politics, rarely in the limelight and never seeking political office. And yet his ‘career’ here – from Black Power firebrand to managing a multimillion budget as head of the Greater London Council’s Ethnic Minority Unit in the 1980s – spells out some of the most important developments in black educational and cultural projects. In this interview, he discusses his identification with Pan-Africanism, his involvement in student politics, his role in the establishment of youth projects and supplementary schools in the late 1960s and 1970s, and his involvement in black radical politics in London in the same period, all of which took place against the background of revolutionary ferment in the Third World and the world of ideas, and were not without their own internal class and ethnic conflicts
