Statistics of extremes under random censoring

We investigate the estimation of the extreme value index when the data are subject to random censorship. We prove, in a unified way, detailed asymptotic normality results for various estimators of the extreme value index and use these estimators as the main building block for estimators of extreme quantiles. We illustrate the quality of these methods by a small simulation study and apply the estimators to medical data.Comment: Published in at http://dx.doi.org/10.3150/07-BEJ104 the Bernoulli (http://isi.cbs.nl/bernoulli/) by the International Statistical Institute/Bernoulli Society (http://isi.cbs.nl/BS/bshome.htm

Transcriptional regulation of Banana EIN3-like genes: correlation with ethylene fruit responsiveness and ripening processes

Ethylene signal transduction initiates with ethylene binding at receptor proteins and terminates in a transcription cascade involving the EIN3/EIL transcription factors. In order to get more insights into the ethylene responsiveness process of banana fruit, we have isolated from banana fruit four cDNA homologs of the Arabidopsis EIN3/EIN3-Like gene, MaEILs (Musa acuminata ethylene insensitive 3-like). Sequence comparison with other banana EIL genes already registered in the database led us to conclude that, at this day, at least 5 different genes namely MaEIL1, MaEIL2/AB266318, MaEIL3/AB266319, MaEIL4/AB266320 and AB266321 exist in banana. Expression of these genes were further analysed in peel and pulp tissues, in relationship with changes of fruit ethylene responsiveness and ripening processes. MaEIL mRNAs were detected in all examined tissues but at lower level in peel than in pulp. According to tissues, MaEIL genes were differentially regulated by ripening and ethylene in mature green fruit. MaEIL2/AB266318 was the unique ripening- and ethylene-induced gene, MaEIL1, MaEIL4/AB266320 and AB266321 genes were down-regulated while MAEIL3/ AB266319 presented an unusual pattern of expression. Interestingly, a marked change was observed mainly on MaEIL1 and MaEIL3/AB266319 mRNA accumulation, concomitantly with changes in ethylene responsiveness of fruit. Data presented in this study suggest the importance of a transcriptionally step control in the regulation of EIL genes during banana fruit ripening. (Résumé d'auteur

Sciunits: Reusable Research Objects

Science is conducted collaboratively, often requiring knowledge sharing about computational experiments. When experiments include only datasets, they can be shared using Uniform Resource Identifiers (URIs) or Digital Object Identifiers (DOIs). An experiment, however, seldom includes only datasets, but more often includes software, its past execution, provenance, and associated documentation. The Research Object has recently emerged as a comprehensive and systematic method for aggregation and identification of diverse elements of computational experiments. While a necessary method, mere aggregation is not sufficient for the sharing of computational experiments. Other users must be able to easily recompute on these shared research objects. In this paper, we present the sciunit, a reusable research object in which aggregated content is recomputable. We describe a Git-like client that efficiently creates, stores, and repeats sciunits. We show through analysis that sciunits repeat computational experiments with minimal storage and processing overhead. Finally, we provide an overview of sharing and reproducible cyberinfrastructure based on sciunits gaining adoption in the domain of geosciences

Socioeconomic inequalities in child and maternal health care in Cameroon

http://onlineresearchjournals.org/JSS/pdf/2012/nov/Nkwenkeu%20et%20al..pdfInternational audienceIn developing economies, a number of investigations have highlighted the fact that the increase in health expenditure will only contribute to poverty reduction if such expenditure is efficient and if access to health services becomes more equitable. This paper measured inequality trends in maternal and child health services access and use in Cameroon where health policies were redirected in the 90s. Using data from Demographic and Health Surveys (1991, 1998 and 2004), the relationship between socio-economic status and health inequalities was assessed. Concentration Index and an accurate estimate built from the capability theory were used to measure inequality trends in socio-economic status. The results show that the policies and interventions have been more effective in reaching the better-off than the worst-off. Increase in total health care access and use were detected for both variables (DPT3 and assistance at delivery) with concentration Index showing improved movements through equal distribution. This observation was contradicted by Lorenz curve for assistance at delivery. Trend differentials observed from health index reveal a significant correlation between health outcomes, deprivation and geographic affiliation. Health services access and use are determined by both socio-economic status and a number of factors including resource allocation and contextual factors. In such context, improvements in the monitoring of healthcare distribution is important to be carry out at both national and sub-national levels, especially in countries that have undergone decentralization and where socio-cultural factors may greatly differ from one region to another

Promoting universal access to health services in post-conflict situations : what role can large scale cash transfer programmes play for better outcomes ?

11 p.Making well-informed decisions about how best to achieve MDGs depends on the ability of public policy makers in accessing the best available evidence about what is known to work and what could be potential benefits, and ways to integrate solutions into complex and often under-resourced health systems. Conditional cash transfer programmes have been largely explored as a policy for improving the education and health outcomes of poor children in developing countries as well as a tool for long-term poverty alleviation; but needs to be appropriate to the context and both fiscally and politically affordable. In DRC, the crisis and conflicts of the past decades severely affected the health status of the population and degraded the health system. Consequently, efforts in reducing infant and under-five morbidity and mortality are seriously hampered by widespread poverty and economic deregulation. The aim of this paper is to question the feasibility and affordability of cash transfer compared to 2 alternatives: an outreach health and nutrition programme with a behavioral change communication component and the elimination of basic health care user fees. The results show that children health outcomes may instead be driven by the equal distribution of quality services through outreach health and nutrition programmes (20% to real GDP) than a large scale health-oriented conditional cash transfer (25.9% to real GDP). A number of issues is outlined with regard to the country's socio-economic and political context : (i) health-oriented conditional cash transfer cannot operate in DRC due to supply-side constraints and lack of health supply strategy, logistics and engineering ; (ii) targeting is somewhat time consuming and irrelevant in such context with a headcount averaging 77% ; (iii) outcomes of a geographic focused cash transfer programme could be expected on improvement of nutritional status, but less on the rise of health demand and would be difficult to scale-up
