双元合法性视角下环境信息披露研究评述
政府合法性 市场合法性 环境信息披露 整合框架
2018/5/9
研究环境信息披露可以从多个角度进行,选取双元合法性这一视角剖析企业披露行为的动机及引起的后果。通过梳理现有文献的环境信息测量方式与披露动因,构建基于政府合法性和市场合法性两个维度的环境信息披露2×2整合框架,并分析了四个象限的可能后果。在此基础上对环境信息披露的未来研究方向进行了展望。
The Voter Model in a Random Environment in Z^d
voter model random walk random environment duality
2016/1/25
We consider the voter model with flip rates determined by(μ e ,e ∈ E d ), where E d is the set of all non-oriented nearest-neighbour edges in the Euclidean lattice Z d . Suppose that (μ e ,e ∈ E d ) a...
A Bayesian localised conditional auto-regressive model for estimating the health effects of air pollution
Air pollution and health Conditional autoregressive models Spatial correlation
2013/6/14
Estimation of the long-term health effects of air pollution is a challenging task, especially when modelling small-area disease incidence data in an ecological study design. The challenge comes from t...

What is the response of the climate system to anthropogenic forcings? This question is addressed typically using projections from climate models. The uncertainty surrounding current climate projection...
Classification with Asymmetric Label Noise: Consistency and Maximal Denoising
Classification Asymmetric Label Noise Consistency Maximal Denoising
2013/4/27
In many real-world classification problems, the labels of training examples are randomly corrupted. Previous theoretical work on classification with label noise assumes that the two classes are separa...
在经济社会活动中,由于人口、资源与环境的非公平分配引发了区域内的矛盾与冲突,从而制约了区域可持续发展。如何化解区域的矛盾与冲突,实现人口、资源与环境的公平性,本文试图以博弈论来研究这一问题。首先本文对区域内代际公共资源与环境公平性作博弈分析,揭示了若没有制度安排与约束,区域内非公平性、非协调性是普遍存在的现象。其次本文对区域内公共资源与环境公平性作博弈分析,揭示了代内公共资源与环境利用的非公平性。...
环保意识调查问卷的Logistic模型
logistic模型 方差分析
2013/8/22
本文应用多元统计分析中的方差分析,logistic模型等方法对环保意识调查问卷反馈的信息进行统计分析,建立被调查企业对环境保护意识的logistic模型,进而可对企业家的环境保护意识的好坏进行判断。
对环境经济核算的总体认识
环境经济核算 经济 环境
2013/8/22
环境经济核算缘起于两个相互联系的事实。事实之一是环境问题越来越深入地介入了人类的社会经济生活,成为国家和国际社会管理中共同面临的问题。在国际社会所倡导的可持续发展战略中,最重要的方面就是处理好经济、社会与环境之间的相互关系,尤其是经济发展与环境保护之间的关系。与上述事实相联系的另一个事实是,为管理所必须的信息数据系统不能满足可持续发展管理之需要,尚没有一个数据系统能够较好地反映出经济与环境之间的相...
试论环境统计学的建立
社会经济 国民经济 环境统计
2013/8/22
随着社会经济的发展,社会与环境、经济与环境之间的问题日益严重,已影响到整个国民经济的均衡发展,因此,对环境统计理论、指标体系的研究已引起了中国统计学界的重视。建立独立的环境统计学不仅对建立有中国特色的统计理论、方法体系有着重要意义,而且对于完善中国宏观经济统计监测系统,保持经济的可持续发展战略的实现,建立大统计学科有着重要的现实意义。本文拟就建立环境统计学有关的几个主要问题作初步的研究与探讨。
On non-stationary threshold autoregressive models
explosive TAR(1) model least-squares estimator unit root TAR(1) model
2011/7/19
In this paper we study the limiting distributions of the least-squares estimators for the non-stationary first-order threshold autoregressive (TAR(1)) model. It is proved that the limiting behaviors o...

Performance period determination and bad definition for credit scorecard has been a mix of fortune for the typical data modeler.
Lipschitz Bandits without the Lipschitz Constant
Lipschitz Bandits Constant strategy environments
2011/6/20
We consider the setting of stochastic bandit problems with
a continuum of arms. We first point out that the strategies considered so
far in the literature only provided theoretical guarantees of the...
