The Spillover Effects of Environmental Regulations: A Perspective of Chinese Unregulated Firms' Tax Burden

Previous studies focus on the direct impacts of environmental regulations while paying less attention to spillover effects. Taking the Eleventh Five-year Plan in China as a quasi-natural experiment, our results show that environmental regulations significantly increase the tax burden of unregulated firms. Environmental regulations generate spillover effects on firms that should not be subjected to regulatory policies. Further channel analysis shows that the fiscal pressure of local governments caused by environmental regulations is a major channel for the increase in the tax burden of unregulated firms. Finally, according to the heterogeneity results, the spillover effects are more pronounced in small firms, non-state-owned enterprises, and provinces with stricter enforcement. Our findings emphasize the additional costs of environmental policies, and the government should consider these costs when formulating policies.     

How Does Corporate Social Responsibility Affect Corporate Continuous Innovation?

From the perspective of sustainable development, this paper analyzes the impact of corporate social responsibility (CSR) on the corporate continuous innovation based on the theory of innovation economics and the demand for innovationdriven development, and then conducts a series of empirical tests based on a sample of Chinese A-shared listed companies from 2008 to 2016. The results show that better CSR performance is conducive to the continuous innovation, and this positive relationship is more pronounced for firms with voluntary accounting information disclosure, for firms of non-high-technology industries, and when policy uncertainty is high. This paper not only enriches the literature on CSR but also provides theoretical references for the innovation practice of enterprises under the innovation-driven strategy.     

基于持续到达信号强度的辐射源定位方法

为了提高辐射源的定位精度，提出了一种基于持续到达信号强度的定位方法。通过在特定区域内随机分布5个以上观测点，在其观测点持续监测信号源频率的电磁波信号强度，根据监测到的每个观测点的信号强度和持续时间，以及电磁波在自由空间中传输的距离与损耗的关系，采用多元线性回归的方法推算出辐射源的三维坐标完成辐射源定位。结果表明，观测点位置误差和各观测点监测时间误差是降低发现目标的成功率和精度的主要因素；观测点的测量误差对定位成功率和定位精度的影响较小；增加监测点数量可明显提高定位成功率和定位精度，但会增加成本；增加持续监测的时间可在监测点数量较少的情况下，有效抵消位置误差、时间误差对定位成功率和定位精度产生的影响，达到比增加测点数更好的效果。所提辐射源定位方法可在不增加硬件成本的基础上，以降低实时性为代价，大幅度提高定位成功率和定位精度，可适用于对实时性要求较低的电磁辐射源定位场景。

Examining consumers' continuous usage of multichannel retailers' mobile applications

This paper examines the variables influencing a consumer's satisfaction and continuous use of a multichannel retailer's mobile application. Drawing upon the Expectation Confirmation Model for Information Technologies, post-adoption literature, and consumer behavior literature, we assess pertinent factors on the continuous usage of multichannel retailers' mobile apps. Through a sample of 1009 consumers who retained a retailer's mobile app for more than 6 months and conducting Structural Equation Modelling, the findings illustrate that utilitarian variables (perceived usefulness, ease of use, and personalization), hedonic variables (perceived enjoyment), and a brand-related variable (consumer loyalty intention toward the retailer's brand), play a significant role in influencing continuous usage of multichannel retailers' mobile apps. In contrast to e-commerce research, the study outlines that escapism plays a negative role in both consumer satisfaction and intention to continue to use a multichannel retailer's mobile app. Previous research points to the fact that consumers' retention of retailers' apps is low. This paper contributes to the emerging literature on consumers' continuous use of retailers' mobile apps through enhancing our understanding of technology and non-technology-related variables.     

RS码编码参数的盲识别

针对现有的RS（Reed-Solomon）码盲识别计算复杂度较大的问题，提出了一种新的识别方法。首先统计不同码长分组时的码重分布，并定义与理论码重分布之间的相似度系数，通过计算找出最相似的一组即对应正确的码长；然后建立二元假设，并确定判决门限对码根进行判定；通过遍历域内所有的本原多项式，找出完整的连续码根分布，进而完成生成多项式的识别。仿真结果表明，所提方法的计算量较其他方法明显减少，并能有效完成码长和生成多项式的识别，在误码率小于10－3时，对常用RS码的识别率能达到90%以上。

UNRAVELLED HOMES: Forced Evictions and Home Remaking in Jakarta

This article explores the contours of modernization in the unmaking and remaking of homes among evicted and resettled families in highrise housing. We examine the trajectories of forced eviction by drawing upon interviews with 17 individuals from nine evicted families who have transitioned from living in informal settlements to highrise social housing (rusunawa) in Jakarta. Drawing on two strands of literature—‘developmental idealism and the family’ from population studies and the critical geographies of ‘homemaking’—we argue that the demolition of houses is but an initial event in a long, quiet and subtle, yet profoundly defining, process of ‘upgrading’ families as part of ‘improving’ society, according to developmental logic. The disciplining of the urban poor does not end with the demolition of their houses, but rather continues as part of the fulfilment of shelter. This article attends to the slow unravelling of home hidden and embedded in post-eviction everyday lives, which are often overlooked because of the overt and violent brutality of forced eviction. While eviction can be seen as the violent visual expression of developmentalism, we argue that the relocation in rusunawa is where this ideal permeates into daily domestic life, making mundane activities a battleground for different ideals of ‘home’.
