Analyst coverage and lawsuit risk

In this study, we use a unique, hand-collected dataset of employee lawsuits and study the impact of analyst coverage on labour relations. We find that an increase in analyst coverage lowers the work-related litigations. In addition, we show that an increased number of analysts lowers the litigation cost, measured by settlement fees and attorney fees. Our results suggest analysts have an important impact on employee relations. Our research enriches the literature on employment practices and analyst coverage.

我国消费信用存在的问题与对策探讨

消费信用是我国经济发展的内在动力。然而,目前我国消费信用存在着诸如消费信用品种及其提供者缺乏、风险控制能力不足、法律法规不健全等问题。今后,我们应该转变消费观念,倡导居民消费信用,健全个人消费信用体系,建立和完善相关配套法律法规等,从而使我国的消费信用更加科学有序地发展。     

USING LEGISLATION TO REDUCE ONE‐TIME PLASTIC BAG USAGE

Plastic bag litter generates serious environmental concerns and poses a risk to wildlife. As this does not seem to be a problem which can be resolved by the private sector alone, or by ‘Coasean’ negotiation, legislation is proposed, particularly focusing on ‘one‐use’ bags. This article surveys legislation worldwide, while concentrating on lessons from the United States and the United Kingdom. The issues are more complex than is often assumed. While environmentalists argue for restriction and ultimate elimination of one‐use bags, manufacturers, especially those that have reformulated the composition of their bags, see legislation as an overreaction to a problem that is already being addressed within the industry. They cite evidence that, when used within a comprehensive recycling programme, plastic bags are not only cost‐effective but a sound use of our limited resources. Bans or restrictions can have knock‐on effects which can create new problems.     

农业技术扩散的时间过程及空间特征分析——以陕西省苹果种植技术为例

农业科学技术只有被广大农民掌握和应用,才能转化为现实生产力,促进农业生产的发展。以陕西省苹果种植技术为例,借助"S型曲线模型"及"重力学模型"对陕西省苹果种植的时空规律进行了研究,发现陕西省苹果种植在时间序列上,其种植面积呈现在波动中上升的趋势,而在空间上,存在等级扩散与渐进扩散相结合的扩散模式,即随着空间尺度的缩减,技术扩散由明显的规模等级扩散向随距离增加扩散强度减弱的渐进式扩散转化。     

电火花线切割机床加工工艺参数的研究

本文阐述了电火花线切割机床的加工机理,利用正交试验的方法,对高速走丝电火花线切割机床加工中的峰值电流、脉冲宽度、脉间比等工艺条件进行了试验的优化设计,减少了试验的次数,缩短了实验周期,提高了效率和效益;从而优化了电火花线切割机床加工工艺参数,提高了加工件的质量;得出了电参数与加工速度和表面粗糙度之间的联系,为进一步研究电火花线切割加工工艺规律提供了基础。     

我国征信管理及制度建设探析

近些年来,我国的经济实践表明,市场经济与金融的发展离不开征信管理;征信管理制度建设,更是确保征信管理工作科学、规范、有效运行的保证。对起步较晚的中国征信管理而言,应通过颁布《征信管理条例》等信用法规,修订现行的有关法律法规,完善征信管理制度。
