跨区域大气污染协同治理研究—以京津冀地区为例

我国大气污染治理从1973年大气环境保护正式启动至今,已有40余年的历程。但区域性、复合型大气污染问题愈发严重,说明现有的大气污染联防联控机制难以彻底解决大气污染治理的“盲点”和“死角”。而网格化管理以数字化、信息化技术为支撑,致力于实现基层资源整合和多元联动管理,可以有效突破大气污染治理的现实困顿。为此,从大气污染协同治理模式的结构出发,探讨了该模式的应用历程,并指出现有治理模式下也面临着责任归属不明、信息建设滞后、公众行动乏力和各主体联动与协调不足的应用困境,最后从责任机制、信息机制、公众参与机制和合作机制四个方面对推进大气污染网格化协同治理模式的应用进行了探讨。     

A Risk Analysis Framework for Cyber Security and Critical Infrastructure Protection of the U.S. Electric Power Grid

The purpose of this article is to introduce a risk analysis framework to enhance the cyber security of and to protect the critical infrastructure of the electric power grid of the United States. Building on the fundamental questions of risk assessment and management, this framework aims to advance the current risk analysis discussions pertaining to the electric power grid. Most of the previous risk-related studies on the electric power grid focus mainly on the recovery of the network from hurricanes and other natural disasters. In contrast, a disproportionately small number of studies explicitly investigate the vulnerability of the electric power grid to cyber-attack scenarios, and how they could be prevented or mitigated. Such a limited approach leaves the United States vulnerable to foreign and domestic threats (both state-sponsored and “lone wolf”) to infiltrate a network that lacks a comprehensive security environment or coordinated government response. By conducting a review of the literature and presenting a risk-based framework, this article underscores the need for a coordinated U.S. cyber security effort toward formulating strategies and responses conducive to protecting the nation against attacks on the electric power grid.     

基于用户电器分类的智能电网实时定价研究

目前，电力运行环境日趋复杂，电力体制改革也在不断进行。针对电力行业逐渐向信息化转变、能源利用率较低以及用户与电力公司交互性不高的现状，提出了一种电器分类实时定价模型。该模型根据不同类型用户的用电器进行分类，电力公司根据不同类型电器的用电情况实时制定出不同种类电器的用电价格，以便引导用户在不同时段根据不同类型电器的电价来使用电器，控制居民的用电行为。智能电表的使用，可使用户了解到不同电器的实时电价，并以此调整使用电器，电力公司也随时得到用户的用电量来调整电价和供电量，达到削峰填谷的作用。此模型既有时效性也能使供需双方用电效用最大化。最后通过数值实验对比分析，结果验证了所提出的模型的有效性。     

Evaluating paired categorical data when the pairing is lost

We encountered a problem in which a study's experimental design called for the use of paired data, but the pairing between subjects had been lost during the data collection procedure. Thus we were presented with a data set consisting of pre and post responses but with no way of determining the dependencies between our observed pre and post values. The aim of the study was to assess whether an intervention called Self-Revelatory Performance had an impact on participant's perceptions of Alzheimer's disease. The participant's responses were measured on an Affect grid before the intervention and on a separate grid after. To address the underlying question in light of the lost pairing we utilized a modified bootstrap approach to create a null hypothesized distribution for our test statistic, which was the distance between the two Affect Grids' Centers of Mass. Using this approach we were able to reject our null hypothesis and conclude that there was evidence the intervention influenced perceptions about the disease.     

One‐Dimensional Inference in Autoregressive Models With the Potential Presence of a Unit Root

This paper examines the problem of testing and confidence set construction for one‐dimensional functions of the coefficients in autoregressive (AR(p)) models with potentially persistent time series. The primary example concerns inference on impulse responses. A new asymptotic framework is suggested and some new theoretical properties of known procedures are demonstrated. I show that the likelihood ratio (LR) and LR^± statistics for a linear hypothesis in an AR(p) can be uniformly approximated by a weighted average of local‐to‐unity and normal distributions. The corresponding weights depend on the weight placed on the largest root in the null hypothesis. The suggested approximation is uniform over the set of all linear hypotheses. The same family of distributions approximates the LR and LR^± statistics for tests about impulse responses, and the approximation is uniform over the horizon of the impulse response. I establish the size properties of tests about impulse responses proposed by Inoue and Kilian (2002) and Gospodinov (2004), and theoretically explain some of the empirical findings of Pesavento and Rossi (2007). An adaptation of the grid bootstrap for impulse response functions is suggested and its properties are examined.
