论动态新证据观——以民事再审新证据为分析对象

民事诉讼新证据问题特别是民事再审新证据问题,是目前理论界和实务界都没有完全弄清楚的一个问题,要解决这个问题应持一种动态新证据观,并用这种观点来审视界定民事再审新证据应考量的因素和民事再审新证据的审查判断。     

"自由时间"论:马克思主义美学在消费时代的新拓展

在人与人的社会关系中,艺术是一种意识形态;在人与物的自然关系中,艺术是一种独特的生产。艺术生产包括存在于"自由时间"中的生产与存在于"必要时间"中的生产;从接受的角度来看,存在于"必要时间"中的艺术就成为存在于"闲暇时间"的消费活动。剥夺艺术"自由生产的时间"而把艺术纳入"必要时间"、"自由消费时间",乃是资本主义生产内在对抗性在艺术活动中的体现。发展马克思"自由时间"论美学,在新的消费时代具有重大现实意义。     

一次交易中的讨价还价策略及其博弈分析

对于市场中的一次性交易,定义了买者的讨价还价策略—“得寸进尺”战略,分两种情况建立了该策略下卖者之间的博弈模型,分别给出了处在信息不对称状态下的买卖双方交易的均衡价,相应地探讨了该均衡价对买卖双方的利与弊。     

自由时差定理与k阶次关键路线的求法

针对项目进度计划管理中如何寻找CPM网络图中任意阶次关键路线等问题,在分析了自由时差概念和特性的基础上提出了k级标准工序、k级特征值和k级标准路线等新概念,推导出自由时差定理和特征值定理,进而利用这些概念和定理给出k阶次关键路线的求法--最小特征值法,分析了算法的正确性,并且得出该算法的计算复杂度为O(n2). 证明了该算法可以通过局部寻优实现全局寻优. 最后结合应用举例论述了该方法的应用范围及特点.     

Science for Policy: A Case Study of Scientific Polarization,Values, and the Framing of Risk and Uncertainty

It is well documented that more research can lead to hardened positions, particularly when dealing with complex, controversial, and value‐laden issues. This study is an attempt to unveil underlying values in a contemporary debate, where both sides use scientific evidence to support their argument. We analyze the problem framing, vocabulary, interpretation of evidence, and policy recommendations, with particular attention to the framing of nature and technology. We find clear differences between the two arguments. One side stress that there is no evidence that the present approach is causing harm to humans or the environment, does not ruminate on uncertainties to that end, references nature's ability to handle the problem, and indicates distrust in technological solutions. In contrast, the other side focuses on uncertainties, particularly the lack of knowledge about potential environmental effects and signals trust in technological development and human intervention as the solution. Our study suggests that the two sides’ diverging interpretations are tied to their perception of nature: vulnerable to human activities versus robust and able to handle human impacts. The two sides also seem to hold diverging views of technology, but there are indications that this might be rooted in their perception of governance and economy rather than about technology per se. We conclude that there is a need to further investigate how scientific arguments are related to worldviews, to see how (if at all) worldview typologies can help us to understand how value‐based judgments are embedded in science advice, and the impact these have on policy preferences.     

我国自贸区纠纷解决机制的建构与制度创新

在建构与国际投资贸易通行规则相衔接的中国自由贸易试验区纠纷解决机制过程中,结合美国在涉对外贸易区立法、涉自由贸易案件管辖权以及完善替代性纠纷解决机制等方面的成熟经验,从国内法与国际法逐步实现制度衔接以及国内自贸区纠纷解决机制中的协调与竞争两个层面加以探讨,以期为我国自贸区纠纷解决机制的建构和制度创新提供借鉴。     

A consistent estimator for logistic mixed effect models

We propose a consistent and locally efficient method of estimating the model parameters of a logistic mixed effect model with random slopes. Our approach relaxes two typical assumptions: the random effects being normally distributed, and the covariates and random effects being independent of each other. Adhering to these assumptions is particularly difficult in health studies where, in many cases, we have limited resources to design experiments and gather data in long‐term studies, while new findings from other fields might emerge, suggesting the violation of such assumptions. So it is crucial to have an estimator that is robust to such violations; then we could make better use of current data harvested using various valuable resources. Our method generalizes the framework presented in Garcia & Ma (2016) which also deals with a logistic mixed effect model but only considers a random intercept. A simulation study reveals that our proposed estimator remains consistent even when the independence and normality assumptions are violated. This contrasts favourably with the traditional maximum likelihood estimator which is likely to be inconsistent when there is dependence between the covariates and random effects. Application of this work to a study of Huntington's disease reveals that disease diagnosis can be enhanced using assessments of cognitive performance.

我国自贸区跨境电商研究现状综述及问题分析

我国自贸区的建立为正在飞速发展的跨境电商提供了新的机遇,同时自贸区跨境电商的发展也存在诸多问题。通过对我国自贸区跨境电商研究现状的分析,发现该课题研究潜力巨大,但存在指导性研究多于基础性研究,定性分析多于定量分析而且实证分析模型、数据不适合,缺乏理论分析等问题,并且对自贸区跨境电商存在的物流、平台、人才问题进行分析并提出建议。目的一是为以后学者的研究指明方向,二是为学者研究我国自贸区跨境电商的发展提供思路。     

陈瑸与雷阳书院

陈瑸生前所在的康熙时代雷阳书院已经被毁,尚未恢复。根据陈瑸本人的文本及后人的记述可以证明:民国二十七年之陈氏《族谱》所记陈瑸任教雷阳书院一事失实。陈瑸任教的是义学,今人所谓陈瑸曾秉铎雷阳书院一说,乃是对历史的误读误判。     

免费师范生角色认同研究

自2007年实行师范生免费教育政策开始,"免费师范生"作为一种特殊身份,倍受社会各界关注,褒贬不一,对于免费师范生角色认同的研究也各抒己见。如今,第一届免费师范毕业生已经走上工作岗位,对于免费师范生的角色认同又有了源于工作实践的诠释,对免费师范生角色认同的内涵、理论层次、影响因素有了进一步的研究和阐释。强化免费师范生角色的认同可以从两方面入手,一是以"研究+实践"的方式,创新教师教育的方式方法,提升免费师范生教育作为终身追求的热情;二是以"实践+反思"的方式,构建新的教师教育体系,提高免费师范生的教育教学能力。
