民营企业诚信建设的博弈分析

根据博弈理论，民营企业信用缺失的根源在于信息不对称及违约成本过低。重复博弈是企业寻求合作的最佳对策，创建重复博弈的连径是建立中介机构、形成信息共享机制和增加违约成本。     

价格听证中提高会计信息质量的现实思考

会计信息在价格听证程序、政府定价和政府指导价决策中具有基础平台作用。然而，出于维护既得利益和攫取更多的私利等目的，一些经营者往往通过垄断信息优势，提供虚假会计信息等手段，人为扩大信息不对称。会计信息不透明已成为制约听证会公正、公开、客观和效率的重要因素。为了减少会计信息不对称造成的负面影响，更好地体现听证程序的公正性，应从会计信息的提交、政府部门初审、社会公告和中介机构评审等四个方面强化经营者会计信息的披露。     

论英汉两种语言交往活动的非对称性

英汉语言之间语言交往活动的非对称性是存在于两种语言之间语言的学习、教授以及语言之间的翻译活动的不平衡性.对于这种非对称性在政治经济文化几个方面所造成的有利于英语国家而不利于中国的后果,可以作出这样的解释:两种语言之间的语言交往活动的非对称性是由于相应的文化的不同特质决定的.由于语言的强势地位依赖于文化的繁荣,文明的昌盛,中华民族唯有发挥自己的创造性,汉文化与语言丰富发展并与英语取得平等的地位才会指日可待.     

融资融券交易对中国上市公司研发支出的影响研究

研发活动是一项高风险的长期投资,上市公司从事研发活动面临着股东与经理之间的委托代理问题。选择融资融券半自然实验,采用DID回归方法和PSM-DID方法检验融资融券交易对中国上市公司研发支出的影响,结果表明融资融券交易会提高研发支出。考虑融资融券交易规模的影响,结果依然稳健。最后检验融资融券对研发的影响渠道,结果表明融资融券会通过降低公司股票的信息不对称来提高公司的研发支出。     

基于不对称开发的快速路横断面优化设计

这篇文章首先介绍了快速路设计中几种常见的横断面型式,然后根据快速路两侧土地开发不对称的情况,结合政府对该地区的用地政策及开发计划,同时分析其两侧交通出行的特点,提出横断面优化设计方案。     

基于读者服务工作中的信息不对称及应对策略

在图书馆读者服务工作中,普遍存在着诸如读者信息素质教育的缺失或滞后;馆藏文献信息资源体系、标识的专业化或滞后;馆员缺乏主动性;流通部门与其他部门之间。机构、制度建设和宣传的缺失或滞后等与读者对图书馆文献信息资源利用的信息不对称现象。应对读者服务中的各种信息不对称现象的策略主要是提高图书馆的内涵竞争力,即馆员和读者的信息素养。     

关于食品安全问题的研究综述——一个经济学的视角

食品安全问题不仅仅是生物学、卫生检疫学方面的问题,更是经济学、管理学、社会学、心理学以及政治学所面临的问题。国内外学者运用信息不对称理论和供应链管理理论的逻辑和方法系统研究了食品安全的涵义和性质、政府规制的成本和收益以及安全食品的供给与消费等问题,大大增强了经济理论对食品安全问题的解释力。相比较国外研究,国内学者还需要在政府规制的逻辑、安全食品的供求机制、纵向协作的治理机制、产权制度等方面进行深入研究。     

Biomechanics of the ski cross start indoors on a customised training ramp and outdoors on snow

An effective start enhances an athlete's chances of success in ski cross competitions. Accordingly, this study was designed to investigate the biomechanics of start techniques used by elite athletes and assess the influence of different start environments. Seven elite ski cross athletes performed starts indoors on a custom-built ramp; six of these also performed starts on an outdoor slope. Horizontal and vertical forces were measured by force transducers located in the handles of the start gate and a 12-camera motion capture system allowed monitoring of the sagittal knee, hip, shoulder, and elbow kinematics. The starting movement involved Pre, Pull, and Push phases. Significant differences between body sides were observed for peak vertical and resultant forces, resultant impulse, and peak angular velocity of the shoulder joint. Significantly lower peak vertical forces (44 N), higher resultant impulse (0.114 Ns/kg), and knee joint range of motion (12°) were observed indoors. Although movement in the ski cross start is generally symmetrical, asymmetric patterns of force were observed among the athletes. Two different movement strategies, i.e. pronounced hip extension or more accentuated elbow flexion, were utilised in the Pull phase. The patterns of force and movement during the indoor and outdoor starts were similar.     

Resting Prefrontal Cortex Asymmetry and Communication Apprehension,Verbal Aggression,and Other Social Interaction Constructs: A Meta-Analytic Review

This study examined the effect of body piercing on perceptions of an employment seeker's credibility, hirability, and attractiveness. Participants (undergraduate students and managers) viewed a photograph of a job candidate who wore either no jewelry, an earring, or a nose ring, and then rated dimensions of the candidate's credibility, hirability, and attractiveness. Analysis indicated that although the candidate's attractiveness ratings were not affected by the type of jewelry he wore, his credibility ratings decreased when he was wearing jewelry, and his hirability ratings decreased when he was wearing a nose ring. These results and their implications are discussed.
