高新技术园区自主创新能力与可持续发展问题研究

建设创新型园区是当前和今后一个时期落实建设创新型国家战略目标的一个重要内容。推进创新型园区建设应以园区社会可持续发展为前提，力求在“全面、协调、可持续”发展的基础上，加快提高自主创新能力。     

内部审计在公司治理中的作用

公司治理是伴随着现代企业而产生发展的,它通过一套制度的安排对企业的权、责、利进行约束。而内部审计正是对这套制度的再监督。本文从公司治理的角度,根据内部审计的涵义和职能,在分析内部审计与公司治理联系的基础上,论述内部审计在公司治理中的作用。同时,结合我国公司治理的现状,揭示内部审计工作存在的问题和相应的解决措施。     

独立的环境法益的刑法保护

本文随着独立的环境法益的提出 ,首先 ,从法哲学的角度对我国的环境刑法未充分重视独立的环境法益的保护进行了价值分析 ,并认为应当赋予自然环境以人格的权利。其次 ,从犯罪学和刑法学的角度对独立的环境法益的刑法保护密切相关的行政从属性理论进行了评判 ,认为只有突破功利的价值观和绝对的行政从属性 ,才能反映环境要素的固有存在 ,才是公正的环境刑法。最后 ,在以上前提下对我国环境刑法在独立的环境法益的刑法保护方面进行了新的论证。     

On an adaptive version of the Metropolis–Hastings algorithm with independent proposal distribution

In this paper, we present a general formulation of an algorithm, the adaptive independent chain (AIC), that was introduced in a special context in Gåsemyr et al . [ Methodol. Comput. Appl. Probab. 3 (2001)]. The algorithm aims at producing samples from a specific target distribution Π, and is an adaptive, non-Markovian version of the Metropolis–Hastings independent chain. A certain parametric class of possible proposal distributions is fixed, and the parameters of the proposal distribution are updated periodically on the basis of the recent history of the chain, thereby obtaining proposals that get ever closer to Π. We show that under certain conditions, the algorithm produces an exact sample from Π in a finite number of iterations, and hence that it converges to Π. We also present another adaptive algorithm, the componentwise adaptive independent chain (CAIC), which may be an alternative in particular in high dimensions. The CAIC may be regarded as an adaptive approximation to the Gibbs sampler updating parametric approximations to the conditionals of Π.     

论中国婚姻法在法律体系中地位研究之误区——兼与婚姻法私法论商榷

国内有关婚姻法在法律体系中地位的主要论述,主要散见于各种教科书和婚姻法修改论争中。主流观点可称为婚姻法私法论,其主张婚姻法属于私法应“回归民法”,并适用私法自治原则,在婚姻法中建立全面的权利体系。然而,有关论述普遍存在论证过程简单、论证逻辑错误、缺乏论证、研究视角单一等问题,而难以具有说服力。有关婚姻法在法律体系中的地位问题,应改变从理论到理论的研究思路,应扎根于社会生活本身,从实际出发,从有利于解决中国婚姻家庭的实际问题出发作扎实的研究。     

从盈余管理角度对独立董事制度有效性的实证分析

文章通过选取上市公司样本,运用均值检验和相关分析等方法从盈余管理角度对我国独立董事制度的有效性进行了实证分析,得出以下结论:独立董事制度的设立对公司盈余管理没有显著影响;独立董事占董事总数的比例与盈余管理之间也没有显著的相关性;自愿设立独立董事的公司与政策规定设立独立董事的公司两者的盈余管理有显著差异,前者的平均值小于后者的平均值。总体上讲我国独立董事制度没能有效监督公司盈余管理行为,其发挥作用还需以公司自身良好素质做平台。     

新时代成人高等教育考试招生改革路径思考

成人高等教育是继续教育、高等教育和终身学习的重要组成部分。新中国成立以来,我国成人高等教育经历了创建、停滞、恢复、改革与调整和跨越式发展五个时期。当前,成人高等教育考试招生工作主要存在招考制度不完全适应和满足社会需求、生源规模和质量有所下降、考务组织和管理能力不足等问题。站在新的历史起点上,成人高等教育考试招生工作应坚持以习近平新时代中国特色社会主义思想为指导,全面贯彻党的教育方针,积极思考和探索改革发展的新路径：以促进教育公平为根本,把牢前进方向;以终身学习理念为指导,重构发展定位;以服务经济社会发展为目标,明晰招生思路;以构建高质量教育体系为主线,深化改革创新,从而实现我国成人高等教育考试招生健康有序发展。     

A Population Approach to Analysis of Variance Models

Several authors have contributed to what can now be considered a rather complete theory for analysis of variance in cases with orthogonal factors. By using this theory on an assumed basic reference population, the orthogonality concept gives a natural definition of independence between factors in the population. By looking upon the treated units in designed experiments as a formal sample from a future population about which we want to make inference, a natural parametrization of expectations and variances connected to such experiments arises. This approach seems to throw light upon several controversial questions in the theory of mixed models. Also, it gives a framework for discussing the choice of conditioning in models     

Inapproximability and approximability of maximal tree routing and coloring

Let G be a undirected connected graph. Given g groups each being a subset of V(G) and a number of colors, we consider how to find a subgroup of subsets such that there exists a tree interconnecting all vertices in each subset and all trees can be colored properly with given colors (no two trees sharing a common edge receive the same color); the objective is to maximize the number of subsets in the subgroup. This problem arises from the application of multicast communication in all optical networks. In this paper, we first obtain an explicit lower bound on the approximability of this problem and prove Ω(g^1−ε)-inapproximability even when G is a mesh. We then propose a simple greedy algorithm that achieves performance ratio O√|E(G)|, which matches the theoretical bounds.

Moment‐Independent Sensitivity Analysis Using Copula

In risk assessment, the moment‐independent sensitivity analysis (SA) technique for reducing the model uncertainty has attracted a great deal of attention from analysts and practitioners. It aims at measuring the relative importance of an individual input, or a set of inputs, in determining the uncertainty of model output by looking at the entire distribution range of model output. In this article, along the lines of Plischke et al., we point out that the original moment‐independent SA index (also called delta index) can also be interpreted as the dependence measure between model output and input variables, and introduce another moment‐independent SA index (called extended delta index) based on copula. Then, nonparametric methods for estimating the delta and extended delta indices are proposed. Both methods need only a set of samples to compute all the indices; thus, they conquer the problem of the “curse of dimensionality.” At last, an analytical test example, a risk assessment model, and the levelE model are employed for comparing the delta and the extended delta indices and testing the two calculation methods. Results show that the delta and the extended delta indices produce the same importance ranking in these three test examples. It is also shown that these two proposed calculation methods dramatically reduce the computational burden.
