Exact inference for exponential distribution with multiply Type-I censored data

In this paper, we focus on exact inference for exponential distribution under multiple Type-I censoring, which is a general form of Type-I censoring and represents that the units are terminated at different times. The maximum likelihood estimate of mean parameter is calculated. Further, the distribution of maximum likelihood estimate is derived and it yields an exact lower confidence limit for the mean parameter. Based on a simulation study, we conclude that the exact limit outperforms the bootstrap limit in terms of the coverage probability and average limit. Finally, a real dataset is analyzed for illustration.     

Covariate‐adjusted borrowing of historical control data in randomized clinical trials

The borrowing of historical control data can be an efficient way to improve the treatment effect estimate of the current control group in a randomized clinical trial. When the historical and current control data are consistent, the borrowing of historical data can increase power and reduce Type I error rate. However, when these 2 sources of data are inconsistent, it may result in a combination of biased estimates, reduced power, and inflation of Type I error rate. In some situations, inconsistency between historical and current control data may be caused by a systematic variation in the measured baseline prognostic factors, which can be appropriately addressed through statistical modeling. In this paper, we propose a Bayesian hierarchical model that can incorporate patient‐level baseline covariates to enhance the appropriateness of the exchangeability assumption between current and historical control data. The performance of the proposed method is shown through simulation studies, and its application to a clinical trial design for amyotrophic lateral sclerosis is described. The proposed method is developed for scenarios involving multiple imbalanced prognostic factors and thus has meaningful implications for clinical trials evaluating new treatments for heterogeneous diseases such as amyotrophic lateral sclerosis.     

信仰消费与阶层分化研究——以"佛纸"为例

"世俗化"是现代社会的潮流,然而浙东农村地区的民间佛教却呈现表象繁荣之景象,以"佛纸"为代表的信仰消费兴盛是其主要表现形式."佛纸"是经过念佛这一赋灵过程的纸钱,是民间佛教的重要宗教产品.目前,"佛纸"呈现出多样化、 等级化、 货币化、 市场化的特征.随着经济阶层分化的出现,社会上层成为信仰消费的推动者和主力军,社会中层成为信仰消费的跟随者,社会下层则扮演着生产者角色,由此形成固定的需求方和供给方.在消费社会背景下,宗教信仰发生异化,赋灵过程可以通过金钱买卖.正是由于佛纸在阶层间流通和买卖,建构出一个表面繁荣的宗教市场,展示出宗教表象上的兴盛状态.     

Optimal RSUs placement with delay bounded message dissemination in vehicular networks

In order to transfer emergency messages from the accident site to the control center as soon as possible, the Roadside Units (RSUs) act as the most important roles in vehicular ad hoc networks (VANETs). However, we always hope to deploy the minimum number of RSUs because of the low market penetration of VANET-enabled vehicles and the deployment cost of RSUs. This paper presents a transmission delay analysis in urban areas with IID vehicles, and then reveal the relationship between the transmission time and message dissemination distance. According to the analysis, the optimal RSUs deployment problem is formulated. We propose three heuristic greedy strategies as code methods of genetic algorithms to solve the optimal RSUs placement problem with delay bound. Simulation results show that the solutions are efficient and the time complexity is lower than those existing algorithms.     

论孙中山民权思想对中国传统民本思想的继承和展开

作者通过对中国传统民本思想与孙中山民权思想在追求的目标、人群划分的理论及君子与先知先觉者的社会义务三大方面的具体对比,认为孙中山的民权思想在价值法则上继承了中国传统的民本思想资源,是民本思想在当时社会背景下的自然展开,从而厘清了孙中山民权思想的渊源。     

情境因素对学习迁移的影响初探

关于学习迁移的机制、范围等研究至今没有一个较为统一的观点。基于学校教育中学习迁移存在的问题,从有关迁移的理论研究出发,从情境学习理论的视角重新审视学习迁移的影响因素,探讨情境因素对迁移的作用机制,可以看到情境因素通过支撑和诱导其他因素促进迁移。     

全面建设小康社会与财政改革刨新——纪念邓小平同志提出“小康社会”目标30年

财政作为国家政权“以政控财,以财行政”的分配体系,在建设小康社会中,通过制度创新、管理创新和技术创新,逐步构建起和市场经济体制相适应的公共财政框架,促进了我国经济社会的全面进步。分税制财政管理体制和新型复合税制奠定了财政服务小康社会建设的体制基础;预算的编制、执行、管理和评价等流程的革新提升了财政服务小康社会建设和助推科学发展的能力;多环节的技术创新则增强了财政服务小康社会建设的科学性、规范性。     

中国对北非阿拉伯国家直接投资动因分析及策略选择

本文以北非阿拉伯国家为例,首先描述了中国对其投资概况,进而运用国际经济学的基本原理对其投资动因进行了分析,最后提出我国对其直接投资应采取的类型及产业选择。本文认为,国内产业结构调整、国家的能源、资源战略多元化及规避贸易摩擦和贸易壁垒是中国对非洲直接投资的中国因素。而稳步的经济发展、相对良好的商业环境及较强的国家竞争力使得北非阿拉伯国家成为中国对非直接投资主要流入地区的根本原因。我国应对北非进行资源导向型投资、出口导向和市场导向型投资和产业导向型投资。投资产业应主要集中于能源、农业、机械制造业及通信产业。     

以"双提升"战略打造知识经济高地——广州开发区转变经济发展方式的实践与探索

国际金融危机的冲击使世界经济进入重大结构性调整时期？中央、国务院明确提出要加快经济发展方式的转变,这是当前和今后我国面临的重大战略任务。本文以广州开发区的实践为基础,对实施“双提升”战略在转变经济发展方式的作用进行了探索和研究。     

社会主义核心价值体系研究的三维视角

本文认为:深度挖掘社会主义核心价值体系对其自身的丰富与发展,对促进党的理论创新,对推动社会的和谐发展,对促进中国特色社会主义的长远发展,都具有重要的理论意义与实践价值.本文从几个方面对社会主义核心价值体系进行了新的阐述:从未来学角度关照社会主义核心价值体系,能为人类提供稳定的预期;在信任学层面阐述社会主义核心价值体系,加强了人类风险的防范;借符号学界定社会主义核心价值体系,人类社会的有序建构将不期而至.
