基于Friedman检验对意式千层面质量的分析

为了研究不同风味意式千层面的特点,本实验主要从5种典型意式千层面着手,通过Friedman检验对不同风味意式千层面的口感风味、色泽、质地、气味及外形等品质进行分析,确定每种风味意式千层面的特点.结果表明,在口感上传统意式千层面最受欢迎,具有酸甜适口、富有满足感、微咸味和不黏牙等特性;在色泽上奶油风味意式千层面最受欢迎,...

农户对农业环境污染影响因素的认识程度实证分析

随着农村经济快速发展,农村环境污染也越来越严重,已经严重影响人民的身体健康.文章在分析国内外学者对农村环境污染问题研究的基础上,通过入户调查座谈,并运用Logistic模型实证检验了农户对农村环境污染影响因素的认知程度.农户环保意识不强,乡镇企业污染严重并是造成农村环境污染的最重要因素,农业生产污染是重要的原因之一.在此基础上提出了提高农民的环保意识、调整乡镇企业产业结构、增加农村环境保护的经费投入等政策建议.     

Just the Right Amount of Ethics Inspires Creativity: A Cross-Level Investigation of Ethical Leadership,Intrinsic Motivation,and Employee Creativity

Based on ideology-infused psychological contract theory and cognitive evaluation theory, this study investigated the curvilinear relationship between ethical leadership and employee creativity. A curvilinear mediation model was proposed to explain the impact of ethical leadership on creativity, using employee intrinsic motivation as the mediator. Applying a two wave sampling design that consist 258 employees and their leaders, we found that employee creativity improved as ethical leadership increased from low to moderate levels. However, the employee creativity improvement was attenuated when ethical leadership increased from moderate to high levels. Furthermore, the study also revealed that employee intrinsic motivation partially mediated this curvilinear relationship. The theoretical and managerial implications are discussed.     

一体化以太无源光网络网管系统的研究及实现

EPON作为宽带接入最有效的方式之一,因其本身具备的优良特性而成为光接入网的最优选择,为电网用电信息采集系统的通信信道建设提供了一种安全、高效的通信方式。但因其研究机构众多,各自网管软件在体系结构、兼容性等方面差异甚大,导致系统在监控、管理及维护上的繁杂。本文在分析了不同研究机构各自网管软件的技术原理,并提出建设EPON一体化网管系统,解决了管理者在使用过程中的信息孤岛问题,从而带来整个网络的安全、可靠运行。     

水文计量管理的基础:加强水文计量标准体系建设——《转子式流速仪》《浮子式水位计》《超声波测深仪》等水利行业计量检定规程出台

水文计量管理工作的最基础环节之一就是建立一套完善的水文计量标准体系,而其最重要的组成部分是水利计量检定规程,这是水文计量领域开展计量管理工作的最根本保障.本文重点对JJG(水利)01-2009<转子式流速仪>、JJG(水利)02-2009<浮子式水位计>、JJG(水利)03-2009<超声波测深仪>等三项水利行业计量检...

国际工程承包中的规模与效益问题

一切商业活动都应以效益为中心,国际工程承包也应如此.但在现实中,很多国内公司不惜以牺牲效益为代价,通过低价竞标而获取合同,企业规模扩大而效益下降,一些公司因为低价而亏损严重,不得不继续以低价拿项目以掩盖亏损,从而使得经营进入恶性循环.如果我们不能够清醒地认识到这一问题,一味追求规模,我们在国际上的处境将令人堪忧.     

Relationship between initiative risk management and firm value: evidence from Chinese financial listed companies

This study considers 189 Chinese financial listed companies between 2009 and 2013 as research samples to establish indicators for evaluating the initiative risk management behaviour of financial enterprises. This work further examines the relationship between initiative risk management and firm value. Results show that financial enterprises could effectively increase firm value by taking initiative risk management measures, such as setting up departments or positions that specialize in risk management, using financial derivative instruments or engaging popular international accounting firms as audit institutions. Moreover, results reveal that the permeability of initiative risk management has an unstable effect on firm value, that is, a nonlinear relationship exists between the permeability of initiative risk management and firm value.     

国家产业政策、地方政府行为与实际税率——理论分析和经验证据

本文从地方政府行为的角度研究国家产业政策对于企业实际税率的影响。理论分析表明,产业政策引致重点扶持行业资本回报率增加,使得地方政府面临降税引资和增税增收的权衡;此时,地方政府将会降低产业政策重点鼓励行业的实际税率。借助国家“五年规划”重点行业的划分度量国家产业政策,我们对理论假说进行了实证检验。研究发现,政策鼓励显著降低了相应行业的实际税率水平;并且地方政府财政收入水平越高,实际税率下降幅度越大;机制分析表明这可能是通过降低对鼓励行业的征税努力的方式实现的。分企业类型研究发现,实际税率的降低主要存在于私营企业而非地方国有企业和中央企业。上述发现对于理解地方政府行为在产业政策中的作用以及产业、财政政策协调有重要意义。
