Le Miraculé de Saint-Pierre : de Cyparis à Chocolat, ou le Noir comme « spectacle »
No full textDans Le miraculé de Saint-Pierre, Gaston-Paul Effa exhume une histoire antillaise mal connue : la survie et les tribulations du rescapé de l’éruption du Mont Pelée qui fit plus de 30 000 morts, en 1902. L’auteur afropéen restitue la vie tragique d’un des rares rescapés du drame, Cyparis.À travers son personnage, l’auteur donne à réfléchir sur l’étrange attraction qu’éprouve l’homme pour son semblable souffrant, démuni, mis en scène dans des kermesses, des cirques des zoos humains. Mêlant fiction et réalité historique, il campe une de ses lectrices qui lui reproche certaines imperfections dans son roman précédent. Dans Rendez-vous avec l’heure qui blesse, Gaston-Paul Effa s’était notamment penché sur un autre personnage fort inconnu jusqu’alors des lecteurs antillais et francophones : Raphaël Elizé, maire d’origine martiniquaise déporté et mort à Buchenwald. Ces reproches adressés par cette fan sont d’autant plus pris au sérieux qu’elle est l’arrière-petite-fille du prisonnier qui miraculeusement survit à l’incendie meurtrier qui raya la population de Saint-Pierre de la Martinique de la terre suite à l’éruption du volcan en 1902.In Le miraculé de Saint-Pierre, Gaston-Paul Effa exhumes an unfamiliar Antillean story: the survival and tribulations of the survivor of the eruption of Mont Pelée who killed more than 30,000 people in 1902. The author restores the tragic life of one of the few survivors of the drama, Cyparis. Through his character, the author reflects on the strange attraction that one feels for his fellow who is staged in carnivals, circuses and human zoos. Combining fiction and historical reality, Effa confronts his readers with his own readership as he narrates how one of his readers, Séraphine, blames him for certain imperfections in his earlier novel, Rendez-vous avec l’heure qui blesse (2016). Gaston-Paul Effa had particularly focused on another character, hitherto unknown to Antillean and French-speaking readers: Raphael Elizé, mayor of Martiniquan origin who was deported to the concentration camps and died in Buchenwald. Séraphine is, moreover, the great-granddaughter of the prisoner who miraculously survived the deadly fire that killed the population of St. Pierre, Martinique, in 1902
Continuous ambulatory peritoneal dialysis: perspectives on patient selection in low- to middle-income countries

The prevalence of chronic kidney disease has been predicted to grow the fastest in low- to middle-income countries (LMICs). There is evidence that people living in LMICs have the highest need for renal replacement therapy (RRT) despite the lowest access to various modalities of treatment. As continuous ambulatory peritoneal dialysis (CAPD) does not require advanced technologies, much infrastructure, or need for dialysis staff support, it should be an ideal form of RRT in LMICs, particularly for those living in remote areas. However, CAPD is scarcely available in many LMICs, and even where available, there are several hurdles to be confronted regarding patient selection for this modality. High cost of CAPD due to unavailability of fluids, low patient education and motivation, low remuneration for nephrologists, lack of expertise/experience for catheter insertion and management of complications, presence of associated comorbid diseases, and various socio-demographic factors contribute significantly toward reduced patient selection for CAPD. Cost of CAPD fluids seems to be a major constraint given that many countries do not have the capacity to manufacture fluids but instead rely heavily on fluids imported from developed countries. There is need to invest in fluid manufacturing (either nationally or regionally) in LMICs to improve uptake of patients treated with CAPD. Workforce training and retraining will be necessary to ensure that there is coordination of CAPD programs and increase the use of protocols designed to improve CAPD outcomes such as insertion of catheters, treatment of peritonitis, and treatment of complications associated with CAPD. Training of nephrology workforce in CAPD will increase workforce experience and make CAPD a more acceptable RRT modality with improved outcomes.

Hydraulic behaviour of higleig-portsudan pipeline at operation and shutdown conditions
No full textExperimental measurements were carried out to correlate rheological properties of Nile blend with temperature within temperature ranges at which Nile blend exhibits Newtonian, non-Newtonian, and solidification behaviours. The developed correlations were used to describe the hydraulic conditions within each kilometre length of the pipeline during operation and the pressure difference required for restarting and flushing every kilometre length of the pipeline after specified shutdown time. Pressure losses within every kilometre length of the pipeline at different flow behaviours during the pipeline operation have been studied and analysed. The required restarting pressure of every kilometre length has also been studied taking into consideration the possibility of crude solidification. The pressure head transverse between every two pump stations and the effect of flow rate on the pipeline overall pressure losses duringoperating conditions were studied. These results have been obtained using numerical software developed by the author
Review of theory and practice literature on Women Entrepreneurship in the Tanzanian Construction Industry: establishing the missing link
No full textThe paper presents a review of the theoretical and empirical literature on Tanzania women entrepreneurs in the construction industry. It also discusses and argues for the aspects that lead to the requirement for a study on women-specific issues. A systematic literature review approach was applied and the member check strategy was used to minimise the author\u27s bias. The literature involved three aspects: motivational factors for women\u27s entry into business, the current situation of women entrepreneurs and influencing factors for the under-representation of women in the industry. The under-representation of Women Entrepreneurs in the Construction Industry (WECI) in the construction industry is caused by various factors, such as cultural background, choice of business and level of confidence. Moreover, the social structures and cultural systems that reinforce the continued subordination and marginalisation of women have major implications in their motives and involvement in business. Given the barriers faced by WECI today, there is a pressing necessity to initiate gender-sensitive empowerment programmes to enable them to succeed in their endeavours. Based on the existing literature, this paper establishes the missing link and proposes a study to formulate a conceptual framework necessary to help the public and private sector initiatives in boosting women entrepreneurship in the Tanzanian construction industry
Priority setting for new systematic reviews : processes and lessons learned in three regions in Africa
No full textCITATION: Effa, E. E., et al. 2019. Priority setting for new systematic reviews : processes and lessons learned in three regions in Africa. BMJ Global Health, 4(4):e001615, doi:10.1136/bmjgh-2019-001615.The original publication is available at https://gh.bmj.comPriority setting to identify topical and context relevant questions for systematic reviews involves an explicit, iterative and inclusive process. In resource-constrained settings of low-income and middle-income countries, priority setting for health related research activities ensures efficient use of resources. In this paper, we critically reflect on the approaches and specific processes adopted across three regions of Africa, present some of the outcomes and share the lessons learnt while carrying out these activities. Priority setting for new systematic reviews was conducted between 2016 and 2018 across three regions in Africa. Different approaches were used: Multimodal approach (Central Africa), Modified Delphi approach (West Africa) and Multilevel stakeholder discussion (Southern-Eastern Africa). Several questions that can feed into systematic reviews have emerged from these activities. We have learnt that collaborative subregional efforts using an integrative approach can effectively lead to the identification of region specific priorities. Systematic review workshops including discussion about the role and value of reviews to inform policy and research agendas were a useful part of the engagements. This may also enable relevant stakeholders to contribute towards the priority setting process in meaningful ways. However, certain shared challenges were identified, including that emerging priorities may be overlooked due to differences in burden of disease data and differences in language can hinder effective participation by stakeholders. We found that face-to-face contact is crucial for success and follow-up engagement with stakeholders is critical in driving acceptance of the findings and planning future progress.https://gh.bmj.com/content/4/4/e001615Publisher's versio
Evolutionary Optimization of Kernel Weights Improves Protein Complex Comembership Prediction
No full textIn recent years, more and more high-throughput data sources useful for protein complex prediction have become available (e.g., gene sequence, mRNA expression, and interactions). The integration of these different data sources can be challenging. Recently, it has been recognized that kernel-based classifiers are well suited for this task. However, the different kernels (data sources) are often combined using equal weights. Although several methods have been developed to optimize kernel weights, no large-scale example of an improvement in classifier performance has been shown yet. In this work, we employ an evolutionary algorithm to determine weights for a larger set of kernels by optimizing a criterion based on the area under the ROC curve. We show that setting the right kernel weights can indeed improve performance. We compare this to the existing kernel weight optimization methods (i.e., (regularized) optimization of the SVM criterion or aligning the kernel with an ideal kernel) and find that these do not result in a significant performance improvement and can even cause a decrease in performance. Results also show that an expert approach of assigning high weights to features with high individual performance is not necessarily the best strategy.MediamaticsElectrical Engineering, Mathematics and Computer Scienc
