积极探索和研究产业援疆模式,有助于实现东西部经济合作,促进产业结构调整,推动新疆自我发展能力的提高。该文基于对口支援政策,总结和借鉴了内地省份飞地经济发展的经验和启示,结合新疆区情,根据产业援疆中的政府作用和资金特点,认为江苏模式、中石化模式、广东模式、山东模式四种较为成功、典型的产业援疆模式及其适用领域,可作为产业援疆借鉴与选择的路径模式,并从产业援疆的市场主体、转移动力、政策体系、运行机制、园区开放等方面就提升产业援疆模式的效率提出了相应的措施和建议。 相似文献

汉代民间的鬼神祭祀并非单纯地以祈福禳灾为目的,它还包含有以祝诅等巫术伤害他人,被伤害者甚至有可能是最高统治阶层。祭祀中害人巫术的存在,无疑会对社会治安、统治阶层本身乃至统治秩序的正常运行造成影响。面对这样的挑战,汉代的统治阶层设立严刑峻法、设置祠祝官进行抵御;而统治阶层中的知识分子将先秦以来限制祭祀规模的传统理念用于现实政治,致力于革新鬼神观念、宣扬"淫祀无福",试图在思想上对民众进行引导。 相似文献

In this paper, we introduce a generalization of the Bilal distribution, where a new two-parameter distribution is presented. We show that its failure rate function can be upside-down bathtub shaped. The failure rate can also be decreasing or increasing. A comprehensive mathematical treatment of the new distribution is provided. The estimation by maximum likelihood is discussed, and a closed-form expression for Fisher’s information matrix is obtained. Asymptotic interval estimators for both of the two unknown parameters are also given. A simulation study is conducted and applications to real data sets are presented. 相似文献

Empirical Bayes estimates of the local false discovery rate can reflect uncertainty about the estimated prior by supplementing their Bayesian posterior probabilities with confidence levels as posterior probabilities. This use of coherent fiducial inference with hierarchical models generates set estimators that propagate uncertainty to varying degrees. Some of the set estimates approach estimates from plug-in empirical Bayes methods for high numbers of comparisons and can come close to the usual confidence sets given a sufficiently low number of comparisons. 相似文献

Conditional value-at-risk (CVaR) model is a kind of financial risk measure that is extensively supported and accepted by international financial community. Its optimized form can be regarded as an optimized certainty equivalent (OCE) risk measurement. In this paper, we mainly discuss and analyze the strong laws of large numbers and the convergence rate of OCE's estimator under α-mixing sequences. The result shows that the almost sure convergence rate of CVaR estimator is given by the results of OCE estimator. Its convergence rate is inversely proportional to the square root of the sample size under certain conditions. Its effectiveness is verified by simulation experiments for two classical α-mixing sequences. 相似文献

Qiu and Sheng has proposed a powerful and robust two-stage procedure to compare two hazard rate functions. In this paper we improve their method by using the Fisher test to combine the asymptotically independent p-values obtained from the two stages of their procedure. In addition, we extend the procedure to situations with multiple hazard rate functions. Our comprehensive simulation study shows that the proposed method has a good performance in terms of controlling the type I error rate and of detecting power. Three real data applications are considered for illustrating the use of the new method. 相似文献

"资源稀释模型"认为,在家庭经济资源一定的情况下,家庭里的孩子数量越多,每个孩子分到的经济资源就会相应减少;而且家庭的经济资源对孩子是否有机会接受高等教育的影响非常重要。笔者从"资源稀释模型(Resource Dilution Model)"这一视角来分析和探讨,上世纪末我国"高等教育规模扩张"政策何以得以顺利实施。 相似文献

Lack of data on daily inhalation rate and activity of children has been an issue in health risk assessment of air pollutants. This study aimed to obtain the daily inhalation rate and intensity and frequency of physical activity in relation to the environment in Japanese preschool children. Children aged four–six years (n= 138) in the suburbs of Tokyo participated in this study, which involved three days' continuous monitoring of physical activity using a tri‐axial accelerometer and parent's completion of a time/location diary during daily life. The estimated three‐day mean daily inhalation rate (body temperature, pressure, saturated with water vapor) was 9.9 ± 1.6 m3/day (0.52 ± 0.09 m3/kg/day). The current daily inhalation rate value of 0.580 m3/kg/day proposed for use in health risk assessment in Japan is confirmed to be valid to calculate central value of inhaled dose of air pollutants in five‐ to six‐year‐old children. However, the 95th percentile daily inhalation rate of 0.83 m3/kg/day based on measurement for five‐year‐old children is recommended to be used to provide an upper bound estimate of exposure that ensure the protection of all five‐ to six‐year‐old children from the health risk of air pollutants. Children spent the majority of their time in sedentary and light level of physical activity (LPA) when indoors, while 85% of their time when outdoors was spent in LPA and moderate‐to‐vigorous physical activity. The results suggest the need to consider variability of minute respiratory ventilation rate according to the environment for more refined short‐term health risk assessment. 相似文献
