休谟与启蒙运动——基于《人性论》引言的思想史考察

当前对休谟的研究常把他和启蒙运动相隔裂.通过对休谟代表性著作《人性论》引言的分析,可以发现他和法国启蒙思想家共享认识世界的“力学模式”和实验方法,都试图将当时在英格兰兴起的“自然哲学”应用于人类境况,都致力于用对人类生活有用的经验研究所产生的新理论代替传统形而上学.同时,休谟对经验主义方法自身的局限有着更为健全的认识,主张在经验和可观察现象范围内的实验方法.这一认识在我们反思启蒙时极富价值.     

The Chinese Road in the Light of Historical Continuity

The Chinese road has deep historical roots. Its most striking feature is that it is marked by historical continuity rather than rupture, and the main force behind this continuity is its intrinsic dynamism and vitality. Unlike the paradigm of Eurocentrism or “Discovering History in China,” the comparative analytical paradigm discovers China through long-term comparisons with corresponding countries in the same time and space in an effort to find positive elements in the history of the Chinese road and to refute the long prevalent theory of Chinese stagnation. Seen over the course of world history, the impetus for the creation of the world’s most brilliant agrarian civilization was endogenous. This impetus was not a momentary “explosive force” but a sustainable institutional drive whose main constituents were the independent farming household, endogenous government capacity and adaptive national governance. In addition to the main theme of “permanent change,” Chinese development had a secondary theme of “cyclical change” which cannot be ignored. The roots of Chinese development are buried deep in the genes of this agrarian nation in the form of sticky institutions, bureaucratic inertia, arbitrary power, etc. Historical continuity provided a foundation for China’s creative revolution and development in modern times, ultimately laying down a socialist development road with Chinese characteristics, although this remains an unfinished relay process.

Anger Expression and Persistence in Young Children

This study investigated anger expression during toy removal (TR) in 92 young Chinese children, two to five years of age, and its relations to their persistence in responding to obstacles during two challenging tasks with highly desirable goals [TR and locked box (LB)] and one challenging task with a less desirable goal [impossible perfect circles (IPC)]. Anger expression during TR was positively associated with persistence during TR and LB but not during IPC. The results highlighted the positive effects of anger in the development of persistence.     

伦理视角下农业的二重特性及农作“时”观念的省思

农业是人类生存和发展的基础和支撑,也是人类最早开始的有计划、有组织从事的社会活动。一方面,与其他人类活动不同,农业需要与大自然打交道,农业生产是在自然场所中显示和展开,自然亲自参与了农业生产的始终。另一方面,从对人类发展的推动来看,农业是人们最早为着满足自身生存需要而从事的一种社会活动。既然农业是作为人类的一种社会活动而存在,它必然体现了人的各方面社会特征和价值。与人参与其他社会活动涉及伦理一样,农业不但具有一般伦理的特性,而且因为它同时涉及人与自然的关系,于是决定了其伦理关注与其他人类活动不同,不只是关注人与人之间的伦理关系,更主要的是关注人与自然之间的伦理关系。农业关注的对象不是人,乃是有生命特性的农作物,这些农作物或者动物具备生命的类特征,而且这些生命特征出于自然,具有自然属性,这一点也决定了人在生产农作物的时候需要遵循自然的规范原则,由此亦决定了农业伦理需要在规范伦理学的框架中加以考察和认知。同时,农业是为着人类生存的需要而产生的,人对农业的判断又显示出功利性,使农业呈现功利性伦理的特征。因而,农业伦理具备了伦理学理论的各个层面,甚至将一些看似矛盾的伦理学理论恰如其分地整合在一起。农业伦理不只是单方面属于哪一个伦理理论,而是融合了伦理学中典型的两个流派即功利主义和义务论。在这种融合中,农业显明出一方面以支撑人的生存为目的,另一方面需要适应自然的客观性特征,于是农业伦理也随之在这两个层面反映出其独具特色的差异性。农业伦理的二重性不只是学理上的一种考量和认定,而且是具体地显明在农业实践之中,农业耕作中的"时"观念就是农业二重特性的实践显现,使农业伦理成为与具体实践相结合的实践理性。     

Adaptive modeling of the human-environment relationship applied to estimation of the population carrying capacity in an earthquake zone

Natural catastrophes such as earthquakes can, in addition to causing loss of life, disrupt the urbanization process through the need for forced population redistribution and the modification of resource and environmental carrying capacity. The population carrying capacity (PCC) of an altered environment following an earthquake is a crucial determinant in the relocation of displaced persons. We use data adaptive methods to model the correlation between the physical environment and human population density in estimating PCC in areas affected by the 2008 Wenchuan earthquake. Comparing actual population distributions with ideal population distributions allows for the identification of villages where population exceeds PCC, or conversely, areas where the environment can support a higher population. Such a comparison can provide the basis for a relocation plan, a critical element of post-catastrophe policy-making.     

被神经性毒剂染毒的蛋白IgG中有机磷加合物的研究

本文对IgG与神经性毒剂的加合物进行了研究。用过量的神经性毒剂(沙林、梭曼、VX、环沙林)对IgG(人、大鼠IgG)进行体外染毒,用胰蛋白酶进行酶解,所得样品用Q Exactive LC-MS/MS方法进行分析鉴定,发现了IgG与神经性毒剂的加合物肽段。其中,从人的IgG中发现了4个被标记的肽段,从大鼠的IgG中发现了1个被标记的肽段,另外,还从肽段的二级谱图中发现了酪氨酸加合物的特征离子碎片。本文首次发现了被神经性毒剂标记的IgG肽段,进而说明IgG是鉴定神经性毒剂中毒的一类重要的标记蛋白。     

Bayes shrinkage estimator for consistency assessment of treatment effects in multi-regional clinical trials

The primary objective of a multi-regional clinical trial is to investigate the overall efficacy of the drug across regions and evaluate the possibility of applying the overall trial result to some specific region. A challenge arises when there is not enough regional sample size. We focus on the problem of evaluating applicability of a drug to a specific region of interest under the criterion of preserving a certain proportion of the overall treatment effect in the region. We propose a variant of James-Stein shrinkage estimator in the empirical Bayes context for the region-specific treatment effect. The estimator has the features of accommodating the between-region variation and finiteness correction of bias. We also propose a truncated version of the proposed shrinkage estimator to further protect risk in the presence of extreme value of regional treatment effect. Based on the proposed estimator, we provide the consistency assessment criterion and sample size calculation for the region of interest. Simulations are conducted to demonstrate the performance of the proposed estimators in comparison with some existing methods. A hypothetical example is presented to illustrate the application of the proposed method.     

基于超总体模型的设计效应分解

本文基于超总体模型研究抽样调查中设计效应的计算问题。首先以随机效应模型为基础，明确了简单随机、二阶段、不等概率和分层抽样对应的超总体模型，进而通过所给模型推导出分层、类集、加权单因素设计效应的计算公式和多因素组合的设计效应计算公式并给出了对应估计量，公式表明：多因素同时存在的组合设计效应等于对应单因素设计效应的乘积。最后，对设计效应的理论值、估计值和真实值之间的关系进行了蒙特卡洛仿真，并利用相对偏倚、相对均方误进行了评价。本文的研究，对复杂抽样设计中正确计算、使用设计效应具有指导意义。
