胡尖山地区长 6、长 4+5 储层有利区预测

摘要：以胡尖山油田长 6、长 4+5 油藏为例，综合应用地质资料、岩芯分析资料、测井资料以及试油资料，开展了长 6和长 4+5 油藏小层划分和对比、单井相分析，建立测井相识别模式，编制小层沉积相平面展布图，进而分析沉积相演化规律；探讨储层砂体展布以及物性分布规律，从而深入认识研究区的储层特征。在此基础上对储层进行流动单元的划分，然后结合试油资料对胡尖山油田长 6、长 4+5 油藏的储层进行有利区域的预测，为油田待开发区域的合理建产开发提供了理论指导     

农村校车安全事故背后的教育公平问题

近年来农村校车事故频发,使得校车安全问题浮出了水面。其实,校车不够规范只是校车事故频发的表层原因,而更深层次的原因却在于城乡教育资源配置的不公平。所以要解决校车安全问题,不仅在于规范校车、提高校车的质量,还在于合理配置教育资源,实现城乡教育公平。     

Generating synthetic data to produce public-use microdata for small geographic areas based on complex sample survey data with application to the National Health Interview Survey

Small area statistics obtained from sample survey data provide a critical source of information used to study health, economic, and sociological trends. However, most large-scale sample surveys are not designed for the purpose of producing small area statistics. Moreover, data disseminators are prevented from releasing public-use microdata for small geographic areas for disclosure reasons; thus, limiting the utility of the data they collect. This research evaluates a synthetic data method, intended for data disseminators, for releasing public-use microdata for small geographic areas based on complex sample survey data. The method replaces all observed survey values with synthetic (or imputed) values generated from a hierarchical Bayesian model that explicitly accounts for complex sample design features, including stratification, clustering, and sampling weights. The method is applied to restricted microdata from the National Health Interview Survey and synthetic data are generated for both sampled and non-sampled small areas. The analytic validity of the resulting small area inferences is assessed by direct comparison with the actual data, a simulation study, and a cross-validation study.     

试论民族地区建立“环境侵权责任社会分担机制”的必要性

环境侵权责任社会分担是一种将因环境侵权行为所造成的损失转移到社会,由侵权行为人以外的主体完全或部分分担损失金额的侵权赔偿责任机制。社会连带理论为其提供了正当性基础。从伦理学、经济学、政治学和社会学角度均能证明民族地区建立环境侵权责任社会分担机制的必要性。     

道路与桥梁专业校企合作共建实践教学基地模式探析

高职院校应培养有较强实践能力的实用型人才。然而,我国高职院校专业教学中的理论教学与实践教学往往难以融为一体,培养出的学生很难达到企业的要求。校企合作共建实践教学基地,是破解此弊端的一剂良方。文章就江西交通职业技术学院校企合作共建实践教学基地做了探析。     

四川民族地区旅游资源开发与生态安全保障机制研究

旅游资源开发一直被认为是促进四川、云南、贵州等西部民族地区地方脱贫致富的重要路径,然而过度的资源开发必将直接危及当地生态安全。四川地处长江上游,其民族地区的生态安全状况关系着长江流域以及整个国家的安全。本文从人与自然、人与社会关系的视角,探寻四川民族地区旅游资源开发过程中自然生态环境、民族文化生态环境的生态安全保障机制,以期切实有效地维护社会和谐稳定发展。

Empirical Uncertain Bayes Methods in Area‐level Models

Random effects model can account for the lack of fitting a regression model and increase precision of estimating area‐level means. However, in case that the synthetic mean provides accurate estimates, the prior distribution may inflate an estimation error. Thus, it is desirable to consider the uncertain prior distribution, which is expressed as the mixture of a one‐point distribution and a proper prior distribution. In this paper, we develop an empirical Bayes approach for estimating area‐level means, using the uncertain prior distribution in the context of a natural exponential family, which we call the empirical uncertain Bayes (EUB) method. The regression model considered in this paper includes the Poisson‐gamma and the binomial‐beta, and the normal‐normal (Fay–Herriot) model, which are typically used in small area estimation. We obtain the estimators of hyperparameters based on the marginal likelihood by using a well‐known expectation‐maximization algorithm and propose the EUB estimators of area means. For risk evaluation of the EUB estimator, we derive a second‐order unbiased estimator of a conditional mean squared error by using some techniques of numerical calculation. Through simulation studies and real data applications, we evaluate a performance of the EUB estimator and compare it with the usual empirical Bayes estimator.     

高校服务农村经济建设的路径研究

晋冀鲁豫边区1942年～1943年抗旱减灾述论

1942年～1943年,晋冀鲁豫边区遭受了百年罕见的大旱灾.旱灾造成边区农业生产下降,人民生活极端困难,社会秩序紊乱.在中国共产党领导下,除了动员各种社会力量互助互济来救灾民之急以外,边区军民主要通过组织群众兴修水利,抢种、补种和大种,植树造林等方式来进行抗旱减灾与生产重建.这些抗旱减灾措施的实施为当时晋冀鲁豫边区最终战胜旱灾和坚持华北敌后抗战发挥了重要作用,也为以后的抗旱救灾提供了可以借鉴的经验.
