Straw Craft, imperial education and ethnographic exhibitions as tightly braided sites of gender production in Haiti and Curaçao

Woven straw work produced in the Caribbean in the early twentieth century represented a small but sustainable percentage of the region’s exports. Following the US occupation in Haiti (1915-1934) handicrafts were promoted as economic ‘development’: commodified folklore fashioned for the delight of visiting tourists. Up until 1946 in Curaçao, as a strategy of the Catholic church’s civilising mission, young women trained to plait the so-called ‘Panama hat’ at technical schools (Roemer, 1977); the products of their labour were often exhibited at international expositions and exported for sale in Europe and the United States. This article argues that missionary education that claimed to modernise, industrialise and revalue local handicraft skills to the benefit of local populations in Haiti and the Dutch Caribbean has instead perpetuated colonial gendered and racialised divisions of labour that prepare and discipline students for factory work in the global textile industries. I use straw artefacts and photographs from the collection of the Dutch National Museum of World Cultures as a starting point to trace the entanglements between imperial education and ethnographic exhibitions as sites of gender production. Drawing on Jean Casimir’s concept of contre-plantation (2001), I explore how histories of indigenous craft during specific periods of resistance in Haiti has nurtured disidentification with a gendered logic of labour exploitation and racial capitalism

A cross-dressed Kanaval

This is a response to images from British artist Leah Gordon’s Kanaval series. Gordon’s photographs feature cross-dressed performers in the carnival of Jacmel, a town on the southern coast of Haiti. This short piece imagines some of the narratives behind the images and reveals how these crossings perform and deform colonial history

O is for Orientalism: the dynamics of the sexual tourist gaze in Laurent Cantet’s Vers le sud/Heading South (2005)

This article explores the Orientalist dynamics of North/South sexual tourism in Laurent Cantet’s Vers le sud/Heading South (2005). The narrative of the film is structured around the self-interested motivations of three white middle-aged bourgeois Western women who travel from North America to Haiti in the late 1970s in order to explore their sexuality in what they perceive as an island paradise, effectively exiling themselves from the codified social behaviour expected of them in their homeland. The women avail themselves of the pleasures offered by young black Haitian men, often in exchange for money or goods, and fuel one-sided fantasies of romantic love with their local hosts, seemingly oblivious to the Orientalist nature of such an imbalance of social and economic power. The article explores the historical context of the political repression and violence of late-1970s Haiti under the Duvalier regime, as well as the manifestations of spatial politics represented in the film. In its Haitian setting, Vers le sud sheds light on a relatively unfamiliar cultural and social milieu for the Western/Northern audience, with the director keenly aware of the exoticism of the subject matter and the impossibility of the film to maintain its neutrality in a problematic engagement with the Orient/South. The article argues that the privileged position of the film’s protagonists is matched not only by Cantet’s directorial gaze, but also by the intellectual detachment of postcolonial scholars such as the article’s authors, who acknowledge that their engagement with the subject matter risks re-enacting the Orientalist dynamics they seek to expose

Investigating local population dynamics of bottlenose dolphins in the northern Bahamas and the impact of hurricanes on survival

This study was made possible with financial support from Earthwatch Institute, Atlantis Blue Project Foundation, with permission to conduct research granted by the Bahamas Department of Marine Resources.Little Bahama Bank in the northern Bahamas supports several populations of bottlenose dolphins (Tursiops truncatus). We provide the first estimates of birth rate and age-class-specific apparent survival rates for the local South Abaco population using data from a long-term (1997–2014) photo-identification (photo-ID) study and use the estimated life history parameters in a population viability analysis (PVA) to predict future population trends. Hurricane events are predicted to become more intense due to climate change but knowledge of how hurricanes may impact cetacean populations is limited. Little Bahama Bank is subject to hurricane activity, so we also investigate the potential impact of hurricanes on calf, juvenile and adult survival. Photo-ID data confirmed the existence of a core adult population with relatively high site fidelity in South Abaco, but also evidence of transient animals. Estimated annual birth rate was 0.278 (95% CI: 0.241–0.337). We found strong support for a decline in apparent survival for all age-classes. Estimated survival declined by 9% in adults (0.941 in 1998, to 0.855 in 2013), 5% in juveniles (0.820 in 2000, to 0.767 in 2013) and 36% in calves (0.970 in 1997, to 0.606 in 2013). Evidence that survival was influenced by repeated hurricane activity leading to increased mortality and/or emigration was stronger for calves and juveniles than for adults. PVA simulations of an assumed isolated South Abaco population showed that declines would lead to extinction within decades, even under the most optimistic scenario. Future work should focus on establishing if South Abaco is part of natural source–sink metapopulation dynamics on Little Bahama Bank by assessing trends in abundance in local populations and establishing how they interact; this will be important for assessing their conservation status in a potentially increasingly changing environment.Publisher PDFPeer reviewe

AIDS-related mycoses: the way forward.

The contribution of fungal infections to the morbidity and mortality of HIV-infected individuals is largely unrecognized. A recent meeting highlighted several priorities that need to be urgently addressed, including improved epidemiological surveillance, increased availability of existing diagnostics and drugs, more training in the field of medical mycology, and better funding for research and provision of treatment, particularly in developing countries

Atomic-accuracy prediction of protein loop structures through an RNA-inspired ansatz

Consistently predicting biopolymer structure at atomic resolution from sequence alone remains a difficult problem, even for small sub-segments of large proteins. Such loop prediction challenges, which arise frequently in comparative modeling and protein design, can become intractable as loop lengths exceed 10 residues and if surrounding side-chain conformations are erased. This article introduces a modeling strategy based on a 'stepwise ansatz', recently developed for RNA modeling, which posits that any realistic all-atom molecular conformation can be built up by residue-by-residue stepwise enumeration. When harnessed to a dynamic-programming-like recursion in the Rosetta framework, the resulting stepwise assembly (SWA) protocol enables enumerative sampling of a 12 residue loop at a significant but achievable cost of thousands of CPU-hours. In a previously established benchmark, SWA recovers crystallographic conformations with sub-Angstrom accuracy for 19 of 20 loops, compared to 14 of 20 by KIC modeling with a comparable expenditure of computational power. Furthermore, SWA gives high accuracy results on an additional set of 15 loops highlighted in the biological literature for their irregularity or unusual length. Successes include cis-Pro touch turns, loops that pass through tunnels of other side-chains, and loops of lengths up to 24 residues. Remaining problem cases are traced to inaccuracies in the Rosetta all-atom energy function. In five additional blind tests, SWA achieves sub-Angstrom accuracy models, including the first such success in a protein/RNA binding interface, the YbxF/kink-turn interaction in the fourth RNA-puzzle competition. These results establish all-atom enumeration as a systematic approach to protein structure that can leverage high performance computing and physically realistic energy functions to more consistently achieve atomic resolution.Comment: Identity of four-loop blind test protein and parts of figures 5 have been omitted in this preprint to ensure confidentiality of the protein structure prior to its public releas

In vivo MRI signatures of hippocampal subfield pathology in intractable epilepsy.

OBJECTIVES: Our aim is to assess the subfield-specific histopathological correlates of hippocampal volume and intensity changes (T1, T2) as well as diff!usion MRI markers in TLE, and investigate the efficacy of quantitative MRI measures in predicting histopathology in vivo. EXPERIMENTAL DESIGN: We correlated in vivo volumetry, T2 signal, quantitative T1 mapping, as well as diffusion MRI parameters with histological features of hippocampal sclerosis in a subfield-specific manner. We made use of on an advanced co-registration pipeline that provided a seamless integration of preoperative 3 T MRI with postoperative histopathological data, on which metrics of cell loss and gliosis were quantitatively assessed in CA1, CA2/3, and CA4/DG. PRINCIPAL OBSERVATIONS: MRI volumes across all subfields were positively correlated with neuronal density and size. Higher T2 intensity related to increased GFAP fraction in CA1, while quantitative T1 and diffusion MRI parameters showed negative correlations with neuronal density in CA4 and DG. Multiple linear regression analysis revealed that in vivo multiparametric MRI can predict neuronal loss in all the analyzed subfields with up to 90% accuracy. CONCLUSION: Our results, based on an accurate co-registration pipeline and a subfield-specific analysis of MRI and histology, demonstrate the potential of MRI volumetry, diffusion, and quantitative T1 as accurate in vivo biomarkers of hippocampal pathology
