细节决定的法律风险

一、人身触电伤亡事件的相关资料保管和事故处理程序中应注意的问题随着供电企业外部环境日趋复杂,触电事故已成为供电企业的一个重大经营风险。2000年至今,宜宾电业局共发生涉电民事案件18起,涉及标的541.84万元。其中,人身触电损害赔偿案件14起,标的453.14万元。2002年11月,宜宾电业局江北供电局发生一名六岁儿童触电伤残案件,索赔标的高达201.5万元。就近几年涉及供电企业的人身触电伤亡赔偿案件看,发案率和索赔金额都呈直线上升趋势。在电力设施上发生触电伤亡事件后,如何采取措施,减少或免除供电企业不应承担的责任,已经成为供电企业必…     

资产评估报告是评估准则制订中的重要内容

资产评估报告是资产评估工作的总结.在具体的评估过程中,由于评估的对象、评估内容和评估时效的不同,评估报告也呈现不同的类型,不可能用单一的报告格式反映不同的报告内容.因此,在各类准则制订过程中应对不同类型的评估报告分别予以规范.     

海南岛休闲农业布局现状的实证分析

[目的]全面分析海南岛休闲农业布局现状,为海南岛休闲农业科学合理规划和均衡协调发展提供决策参考。[方法]文章利用海南岛259家休闲农业企业的地理数据,采用比较、缓冲、密度分析工具,从数量、类型、密度、距离衰减方面实证分析海南岛休闲农业的布局特征,并提出相应的优化对策。[结果](1)海南岛东部、中部和西部休闲农业数量分布比重分别为51%、29%和20%,其中国家级示范点数量分布比重分别为83%、17%和0%;(2)休闲农业主要类型有休闲农庄、观光农园、市民农园和农家乐,除休闲农庄在东部、中部、西部分布较均匀外,其他类型分布较不均衡;(3)距离市县中心越远,休闲农业分布密度越小,95%的休闲农业分布在距离市县中心30km以内,距离市县中心10~15km是休闲农业的高峰集聚区;(4)海南岛休闲农业已在海口、保亭、三亚、澄迈、琼中、琼海、定安、儋州形成8个高度集聚带。[结论]海南岛休闲农业无论在数量、类型和密度上都是东部地区最多,中部次之,西部最少。应积极推进具有农业发展优势的地区,因地制宜拓展产业休闲功能;休闲农业产品类型单一的地区,深度挖掘特色资源和文化内涵;加强休闲农业点与旅游景区、生活服务中心之间的跨区域联系,形成和谐发展的有机旅游整体,使休闲农业真正成为农业转型、农民增收的引擎。     

农户生物菌肥购买意愿及行为的影响因素研究*——基于山东省设施菜农的调研数据

[目的]生物菌肥对于土壤改良、环境改善、食品安全具有重要意义,但目前生物菌肥在整个肥料产业中所占份额较小,迫切需要探讨如何从农户角度提高生物菌肥的施用比例。[方法]基于设施蔬菜农户的数据,构建Bivariate Probit模型,对农户生物菌肥的购买意愿和行为的影响因素进行比较研究。[结果]农户的生物菌肥购买意愿和行为总体上呈现一致性,愿意购买的农户中有97. 77%的农户具有实际的购买行为;但两者的影响因素有所差异,从差异因素来看,质量安全检测对购买意愿具有显著的正向影响,但对购买行为的影响并不显著;农户文化程度、种植年限、对无公害、绿色、有机蔬菜的了解程度,经销商推荐,施肥指导对购买行为具有显著的正向影响。从共同因素来看,生态环境认知变量对购买意愿和购买行为影响不显著。[结论]要推广生物菌肥,需要进一步加强质量安全检测体系对农业行为的约束性,提升经销商的规范经营意识,采用集中招标等灵活的价格政策,提升农户的生态技能,并在保护生态环境方面出台更完善的农业绿色发展政策。

汇率制度选择理论的回顾与展望

汇率制度选择一直是国际金融领域备受关注的一个问题.文章对汇率制度选择的研究方法及视角进行了总结,并对传统的汇率制度选择理论和汇率制度的新进展进行了论述,进而对未来汇率制度选择的研究进行了展望.认为:由于存在"恐浮",应该依据实际实行的汇率制度而不是官方宣布的汇率制度进行研究;从动态角度进行汇率制度转换的研究也是很重要的发展方向;应该对中间与两极汇率制度进行统一的界定,建立支持或反对"中空论"的严格理论框架.     

A Primer on Using Behavioral Data for Testing Theories in Advertising Research

Interactions with and between customers in digital, social, and mobile environments are commonly recorded, producing behavioral data that have the potential to advance advertising research. This article provides an accessible guide on how to leverage such data for advertising researchers who may have thus far relied mostly on lab experiment or survey data. Specifically, we suggest potential sources for behavioral data and present a process for analyzing and interpreting behavioral data. Each step of the process is discussed: exploring, understanding and preparing data; specifying and estimating models; and interpreting and presenting the results. Some fundamental issues with using multiple regression to analyze such data are covered, including standardization, outliers, transformations, multicollinearity, and the omitted variable bias. We also discuss issues that are especially problematic with using behavioral data in advertising research, including endogeneity, count data, data with many zeros, and grouped data. More advanced versions of regression that address these issues are surveyed, including instrumental variables, propensity scoring, generalized linear models, and mixed models. General advice for thinking about behavioral data is provided.     

Debt Covenant Restriction,Financial Misreporting,and Auditor Monitoring*

Theory suggests that financial report-based debt covenants engender incentives for the manager to relax covenant constraints through accounting choices in order to avoid costly covenant violations. Prior studies directly testing this hypothesis in the context of financial misreporting fail to find consistent evidence. Using a more refined measure of debt covenant restriction, we find that debt covenant restriction is positively associated with the probability of financial statement misstatements. This positive association is driven by performance covenants rather than capital covenants and is more consistent with the manager striving to avoid a “false-positive” violation than to delay the violation. Our results also imply that managers resort to both income-increasing and non–income-increasing misreporting to relieve covenant constraints and rely more on the latter when faced with greater earnings management constraints. Additionally, the auditor charges higher audit fees to firms with more binding covenants even outside the violation state, and audit fees increase with constraints relative to both performance and capital covenants, reflecting greater financial reporting risk and bankruptcy risk, respectively. Within capital covenants, we find some evidence of even higher audit fees for tighter intangible-inclusive versus intangible-exclusive capital covenants. Lastly, our evidence suggests that the positive association between covenant constraints and misreporting is attenuated when the auditor has more experience with debt covenants, has greater bargaining power over the client, or faces greater litigation risk.
