建设海峡西岸社会主义新农村的价值选择

建设社会主义新农村,本质是要缩小城乡差距,使农村在加速工业化、城市化的过程中能够与城市共同协调发展,使农民与城市居民一样享受等值不同质的现代生活。以等值不同质为取向增进农民福祉,是海峡西岸社会主义新农村建设的出发点和落脚点。建设海峡西岸社会主义新农村,要树立大资源观,以增量资源为杠杆激活存量资源,构建平等、互动、共福的新型城乡关系。     

Sexual behavior among HIV-positive men who have sex with men: what's in a label?

Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self-labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV-seropositive men who have sex with men. The majority of participants (88%) identified as a top, a bottom, or versatile. Tops were more likely to engage in insertive anal intercourse than bottoms, and bottoms were more likely to engage in receptive anal intercourse than tops, with versatiles reporting intermediate rates of both behaviors. Although the results suggest preliminary evidence regarding the predictive utility of self-labels, sexual behaviors of self-label groups were greatly overlapping. Differences were found among self-label groups in gay self-identification, internalized homophobia, sexual sensation seeking, and anxiety. Results suggest an added value in assessing self-labels in addition to asking about sexual behavior.     

A Quantitative Risk Assessment of Waterborne Cryptosporidiosis in France Using Second-Order Monte Carlo Simulation

A pragmatic quantitative risk assessment (QRA) of the risks of waterborne Cryptosporidium parvum infection and cryptosporidiosis in immunocompetent and immunodeficient French populations is proposed. The model takes into account French specificities such as the French technique for oocyst enumeration performance and tap water consumption. The proportion of infective oocysts is based on literature review and expert knowledge. The probability of infection for a given number of ingested viable oocysts is modeled using the exponential dose-response model applied on published data from experimental infections in immunocompetent human volunteers challenged with the IOWA strain. Second-order Monte Carlo simulations are used to characterize the uncertainty and variability of the risk estimates. Daily risk of infection and illness for the immunocompetent and the immunodeficient populations are estimated according to the number of oocysts observed in a single storage reservoir water sample. As an example, the mean daily risk of infection in the immunocompetent population is estimated to be 1.08 x 10(-4) (95% confidence interval: [0.20 x 10(-4); 6.83 x 10(-4)]) when five oocysts are observed in a 100 L storage reservoir water sample. Annual risks of infection and disease are estimated from a set of oocyst enumeration results from distributed water samples, assuming a negative binomial distribution of day-to-day contamination variation. The model and various assumptions used in the model are fully explained and discussed. While caveats of this model are well recognized, this pragmatic QRA could represent a useful tool for the French Food Safety Agency (AFSSA) to define recommendations in case of water resource contamination by C. parvum whose infectivity is comparable to the IOWA strain.     

A joint-modeling approach to assess the impact of biomarker variability on the risk of developing clinical outcome

In some clinical trials and epidemiologic studies, investigators are interested in knowing whether the variability of a biomarker is independently predictive of clinical outcomes. This question is often addressed via a naïve approach where a sample-based estimate (e.g., standard deviation) is calculated as a surrogate for the “true” variability and then used in regression models as a covariate assumed to be free of measurement error. However, it is well known that the measurement error in covariates causes underestimation of the true association. The issue of underestimation can be substantial when the precision is low because of limited number of measures per subject. The joint analysis of survival data and longitudinal data enables one to account for the measurement error in longitudinal data and has received substantial attention in recent years. In this paper we propose a joint model to assess the predictive effect of biomarker variability. The joint model consists of two linked sub-models, a linear mixed model with patient-specific variance for longitudinal data and a full parametric Weibull distribution for survival data, and the association between two models is induced by a latent Gaussian process. Parameters in the joint model are estimated under Bayesian framework and implemented using Markov chain Monte Carlo (MCMC) methods with WinBUGS software. The method is illustrated in the Ocular Hypertension Treatment Study to assess whether the variability of intraocular pressure is an independent risk of primary open-angle glaucoma. The performance of the method is also assessed by simulation studies.

关于我国科技投入的研究

在我国的社会管理体系中,科学技术日益受到重视。科学技术的发展需要依靠众多的科技人才和巨额的经费支持,需要有明确的任务、目标。但是,在现代社会里,只可能将有限的资源投入到科技发展中去,从而需要在政策上确定合理的投入量、合理的任务目标和合理的投入结构,这就需要对科学技术的投入进行统计研究。     

设立国家综合配套改革试验区推进海峡西岸经济区建设——厦门设立国家综合配套改革试验区的可行性研究

厦门市是我国最早的四个经济特区之一.经过二三十年的建设,厦门特区的经济社会全面发展,人民生活蒸蒸日上;同时也发挥了排头兵的作用,为全国的改革开放进行了先行的探索.然而,随着改革开放的深入以及原有特区政策的普适化,特区发展面临巨大的竞争压力,体制创新任重道远,迫切需要注入新的活力,形成新的发展思路和战略.争取成为国家综合配套改革试验区,无疑是厦门乃至整个海峡西岸经济区未来发展的一次难得机会.因此,厦门必须把握自身优势,发挥特区发展的先行优势和特色,把建立国家综合配套改革试验区作为一项重大的发展战略来看待.

海峡西岸产业投资基金运作机制研究

从筹资、投资、退出以及监管等方面对海西产业投资基金的运作机制进行研究。在筹资机制上,海西产业投资基金规模估计为175～200亿元人民币,首期募集35～40亿元人民币,中期募集90～100亿元人民币,后期募集45～60亿元人民币,基金的存续期为10-15年,基金的组织形式设计为契约型。在投资机制上,海西产业投资基金将突出对台政策,并以推动海西重点产业、支柱产业、特色产业发展和产业结构优化为着眼点,承接台湾科技业转移。在退出机制上,海西产业投资基金将主要倾向于通过即将推出的创业板市场以及海西产权交易市场来实现退出。在监管机制上,海西产业投资基金的监管将实行由上层政府集中统一监管和中层产业投资基金行业协会自律监管相结合,再加基层市场化监督的监管模式。
