防止公职人员利益冲突的路径选择——以人性为视角

公职人员的利益冲突问题是一个新的廉政建设研究领域。国（境）内外实践证明,利益冲突是腐败发生的重要根源,是导致政府行政行为非法性、政府信任危机的必然逻辑结果,其产生根源于人性趋利的本质特性。因此,防止公职人员利益冲突,须以人性趋利的本质特性为基点,以利益阻隔为路径,以制度的针对性、操作性与实效性为目标。基于此须设立防止利益冲突三道防线：建立良好的公职人员职业保障体系,让其不想;加大利益冲突的个人成本,让其不敢;创新权力约束与监督机制,让其不易。     

Using choice experiments to value catchment and estuary health in Tasmania with individual preference heterogeneity*

Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of estuary values. The CE study described in this paper aims to analyse community preferences for NRM options in the George catchment, Tasmania. Catchment health attributes were: the length of native riverside vegetation; the number of rare native animal and plant species in the George catchment; and area of healthy seagrass beds in the Georges Bay, which was used as a measure of estuary condition. Mixed logit models with interactions between socio‐economic variables and the choice attributes were estimated to account for systematic and random taste heterogeneity across respondents. Results reveal considerable variation in preferences towards the attributes and show that value estimates are significantly impacted by the way in which we account for preference heterogeneity. Preference heterogeneity thus needs to be considered when estimating community willingness‐to‐pay for environmental changes. This study further shows little responsiveness to the presented changes in estuary seagrass area.     

Foot‐and‐mouth disease and the Mexican cattle industry

The objective of this article is to analyze the domestic and international effects of a hypothetical foot‐and‐mouth disease (FMD) outbreak in the Mexican cattle industry. A discrete time dynamic optimization model of the Mexican cattle sector is specified, and linked to domestic and international markets. Economic consequences of FMD outbreaks are simulated over time and under different scenarios. Specific findings and general policy recommendations are provided. The study reports a range of outbreaks from localized to large scale and suggests that changes in economic surplus due to FMD range from a positive net gain of $0.89 to $1.6 billion to a net loss of about $67 billion, depending on the specific mitigation strategy and outbreak scenario.     

进城农民工需要满足的行为选择模型

进城农民工能否实现城市化,取决于其行为选择,而这又与进城农民工的需要满足直接相关.本研究以量表测试进城农民工需要状况,再通过因素分析分别从量表中提取因子,用相关分析法找出相关因子,最后用多元回归分析的逐步进入法算出因子间的相关系数和回归系数,根据回归方程建立了模型.

一种带辅助译码比特的Polar码译码方法

在传统的Polar码译码的基础上,引入辅助译码比特,构造了一个辅助的Polar码字以提高译码性能。辅助比特由信道选择辅助窗口内的信息位决定。接收端如译码失败,将进行二次译码尝试。译码方案分两阶段进行：基于相同结构的扩展生成矩阵,将辅助译码比特译出;结合译出的辅助比特,对原码字进行译码,提高译码成功率。仿真结果显示,使用所提方法进行译码,其译码性能明显优于普通串行抵消译码方法;与两种传统的自动重传请求方案相比,能分别获得1 dB和1.9 dB的性能增益。     

Local integration and co‐evolution of internationalizing Chinese firms

This study investigates the integration of internationalizing Chinese firms into local host markets. We explore the market‐driven investment of a new wave of Chinese private and local state‐owned firms in Australia since 2012, which has replaced the initial large‐scale investment in resources by central state‐owned enterprises. Using an in‐depth analysis of nine Chinese firms operating in various sectors of the Australian market, we argue that market integration, adaptation, and bilateral institution‐building through co‐evolution and empowerment of local subsidiaries of Chinese multinational enterprises results in entrepreneurial autonomy and characterizes a new generation of Chinese investors. We propose that Chinese multinational subsidiaries have transferred domestic practices to the Australian market and have reconfigured domestic and host market resources to gain a competitive advantage in their original investment industry and new industries. Our study advances middle‐range theory building and provides a practical understanding of the strengths and weaknesses of Chinese investors, their potential to disrupt local markets, and their responsiveness to market‐oriented institutional guidance. The results of this study suggest that the bilateral institution‐building and resource reconfiguration capabilities of Chinese enterprises can be transferred to other developed and developing markets, including Belt and Road Initiative countries.
