江苏省仪征市真州东园位置考证

东园是仪征历史上最著名的一座园林,也是中国宋代最著名的园林之一,在中国古代园林史上占有重要地位.梅尧臣、苏轼、王安石等人都曾经在园中游览,留下了优美的诗篇,欧阳修为它写了著名的散文《真州东园记》.虽然这座园林在清代已经消失,但是今天许多人士希望能够确定东园遗址的位置,重建这座园林,为仪征保留一份珍贵的历史文化遗产.由于年代久远,仪征当地的地形地貌发生了巨大变化,东园遗迹几乎完全消失;同时,文献中东园位置的记载也是十分简略的,因此,确定它的位置非常困难.在前人研究的基础上,通过查阅文献并结合实地调查,确定了东园遗址的准确位置和边界.东园遗址的位置在以今天文墩遗址为中心,真州城东翼城遗址的南侧,真州城东门遗址的东侧,清代儒学遗址的北侧,小教场遗址的西侧.     

推进《讲话》精神进大学生头脑的若干思考

胡锦涛总书记在庆祝中国共产党成立90周年大会上的重要讲话,以许多重要的新思想、新观点、新论断丰富和发展了中国特色社会主义理论体系,是一篇马克思主义的纲领性文献,也是当代大学生思想政治教育的鲜活教材。高校要从培养中国特色社会主义事业可靠接班人的政治高度,建构从课堂教学到第二课堂活动再到社会实践的教育模式,及时、主动、自觉地做好《讲话》精神进大学生头脑的工作。     

A robust automatic clustering algorithm for probability density functions with application to categorizing color images

This study develops a robust automatic algorithm for clustering probability density functions based on the previous research. Unlike other existing methods that often pre-determine the number of clusters, this method can self-organize data groups based on the original data structure. The proposed clustering method is also robust in regards to noise. Three examples of synthetic data and a real-world COREL dataset are utilized to illustrate the accurateness and effectiveness of the proposed approach.     

Development of predictive signatures for treatment selection in precision medicine with survival outcomes

For survival endpoints in subgroup selection, a score conversion model is often used to convert the set of biomarkers for each patient into a univariate score and using the median of the univariate scores to divide the patients into biomarker‐positive and biomarker‐negative subgroups. However, this may lead to bias in patient subgroup identification regarding the 2 issues: (1) treatment is equally effective for all patients and/or there is no subgroup difference; (2) the median value of the univariate scores as a cutoff may be inappropriate if the sizes of the 2 subgroups are differ substantially. We utilize a univariate composite score method to convert the set of patient's candidate biomarkers to a univariate response score. We propose applying the likelihood ratio test (LRT) to assess homogeneity of the sampled patients to address the first issue. In the context of identification of the subgroup of responders in adaptive design to demonstrate improvement of treatment efficacy (adaptive power), we suggest that subgroup selection is carried out if the LRT is significant. For the second issue, we utilize a likelihood‐based change‐point algorithm to find an optimal cutoff. Our simulation study shows that type I error generally is controlled, while the overall adaptive power to detect treatment effects sacrifices approximately 4.5% for the simulation designs considered by performing the LRT; furthermore, the change‐point algorithm outperforms the median cutoff considerably when the subgroup sizes differ substantially.

The disaster relief and social work after the Wenchuan earthquake in Mainland China

ABSTRACT

This paper mainly focuses on the development of disaster social work in Mainland China and the intervention of social work in disaster relief. Before the Wenchuan earthquake and in the initial stage of post-earthquake, disaster social work was mainly based on individual psychotherapy; from the earthquake to the year of 2012 in which post-earthquake recovery and reconstruction was completed, the disaster relief began to emphasise community building and integration, while the basic framework for disaster social work was also established. Social workers begin to explore the new mode of developmental and localised disaster social work. By combining with the practical experiences from disaster social work, this paper tries to highlight the dilemmas confronting disaster relief in Mainland China and put forward some corresponding countermeasures and suggestions, which could improve the future disaster relief system in Mainland China.

央行沟通对于货币政策实际干预的预测能力研究

信息沟通有助于公众理解和预测货币政策的实际干预,进而提高货币政策有效性。研究中国人民银行的信息沟通对实际政策干预的预测能力需要解决沟通文本的测度问题,同时考虑实际政策干预多工具并用的复杂性。基于此,本文通过文本分析方法提取《货币政策执行报告》的信息,进而考察央行沟通对于货币政策实际干预的预测能力。研究表明,整体而言,市场对中国人民银行“听其言”有助于“观其行”。具体来看,央行沟通对于直接可控的基准利率和存款准备金率具有持续的预测能力,但对于市场利率的预测能力较差,对于M2增长率的预测甚至存在方向不一致的情况。     

汉语网络语言影响内地藏生汉语习得的原因与对策

汉语网络语言影响藏生汉语习得的情感，影响藏生汉语习得中“可理解的语言输入”的数量和质量，影响藏生对汉语社会文化的适应和趋同程度。这些影响主要与汉语网络语言使用失范、内地藏生汉语习得与汉语网络环境脱节、汉藏文化障碍影响汉语网络语言的推介等因素相关。据此，文章从二语习得的角度提出解决对策：培养藏生对汉语网络语言的价值观和情感；引导和规范汉语网络语言，优化网络环境；寻求藏生汉语习得与网络社会生活的契合点，提高“可理解的语言输入”的数量和质量。
