Concentration functions and Bayesian robustness

The concentration function, extending the classical notion of Lorenz curve, is well suited for comparing probability measures. Such a feature can be useful in different issues in Bayesian robustness, when a probability measure is deemed a baseline to be compared with other measures by means of their functional forms. Neighbourhood classes Γ of probability measures, including well-known ones, can be defined through the concentration function and both prior and posterior expectations of given functions of the unknown parameter are studied. The ranges of such expectations over Γ can be found, restricting the search among the extremal measures in Γ. The concentration function can be also used as a criterion to assess posterior robustness, when considering sensitivity to changes in the likelihood and the prior.     

试论《学生伤害事故处理办法》

学生人身安全是社会各界普遍关注的热点问题，近年来，由于有关学生人身伤害事故处理缺少具体法律规范，给其妥善处理带来很大难处，更影响到素质教育的深入发展。教育部经过多年调查研究及借鉴有关经验于2002年6月25日颁布了《学生伤害事故处理办法》，该办法具有较强的针对性、实用性和可操作性。本文从学生伤害事故的范畴；学生伤害事故责任的归属和认定；学生伤害事故损害的赔偿三个方面予以论述。     

发展信用评估业的障碍及其措施

Addressing the Dependency Problem in Access Security System Architecture Design

The objective of this research is to present a method for evaluating the performance of access control security systems, such as airport security operations. This requires the examination of security system architectures, which involve security technology devices and the algorithms that coordinate their operations. Dependence between device responses in multiple-device systems is a critical practical issue in assessing the performance of such architectures, though no results on this problem have appeared in the literature. This paper presents a method for evaluating when multipledevice security systems with overlapping capabilities are cost-effective. This is achieved using a dependency structure for security system devices to quantify how various technologies interact and to measure the impact of device dependence on system error probabilities. A measure of device response dependence for a two-device system is defined and its properties are explored, including bounds on the dependency measure. The effect of dependence on the system Type I and Type II error probabilities is examined for the two-device system. System performance is compared for independent vs. dependent device responses and desirable dependence relationships are identified. Results are also presented for a cascading sequence of devices. An example is presented to illustrate the results for the two-device system. Implications of these results are discussed, such as how they can be used to identify the optimal use of security devices and to determine whether new technologies warrant investment.     

传统思维定势：管理创新的内阻及应对

管理作为一种文化活动 ,既是实践者个体意识的展现 ,也是过去和现在文化力量的产物。过去的文化通过传承总是以特定的方式影响人们对当今管理现象的客观判断。为摆脱这种成见 ,获得思维上的自觉 ,就必须进行主动诘问 ,并从特定的文化背景中探究管理现象的具体条件 ,为思维活动确定基准。     

利用非价格手段摆脱价格竞争

价格竞争是把双刃剑,尽管它会带来竞争者期望的高市场占有率或潜在利益,也会使竞争双方两败俱伤,但价格竞争依然频频发生。价格竞争的产生有自身原因,也有竞争对手的原因,要正确看待并应对价格竞争。企业理智的做法不是从价格上做文章,而要从产品创新、加快技术研发速度及价格创新等非价格手段这一战术角度出发,依靠提高竞争力来摆脱价格竞争,以期进入竞争的良性循环,战胜竞争对手。     

辽宁现代物流业发展战略研究

辽宁物流业有良好的发展基础,也存在许多困难和制约因素。为了更好地适应全面建设小康社会的需要,把握机遇、迎接挑战,必须确立正确的战略发展目标,采取有效的战略保障措施。     

内部控制、信息不对称及控制对策

企业内部控制制度设置的目的是保障财务报告的可靠性、业务活动的效果与效率、对适用法律法规的遵从等,但由于非对称信息的存在,致使内部控制难以完全发挥其功能,影响内部控制目的的实现。通过对内部控制中不对称信息的分析,缺乏真正的委托人是问题严重性存在的根源,因此建立起拥有完全产权的委托人体制,是解决问题的根本。     

推动农业科技制度创新的财税措施

我国农业科技制度正面临着全面创新的新形势,而农业科技制度的创新必须依靠国家强有力的财税措施来推动。为此,必须改革各类农业科研院所的财政关系,大力培育农业科技企业,推动农业科技机构创新;立足学科前沿、产业化和区域特色,拨付必要的财政资金,加强农业科技基础设施建设,推动农业科技基地创新;改革财政经费的拨付方式,引入竞争,强化激励,推动农业科技机制创新;加大财政投入和税收优惠力度,充分发挥市场作用,多渠道筹集农科资金,保证农业科技人才、资金和信息的最大供给,推动农业科技资源创新。     

受保护的技术措施范围的探讨

我国《著作权法》对受保护的技术措施的范围规定的不很明确。文章从技术措施的自身特点出发 ,围绕着“权利人和社会利益之间的平衡”这一原则 ,探讨受保护的技术措施的范围。一方面 ,攻击性的技术措施和其他不利于社会公共利益的技术措施不在保护之列 ;另一方面 ,制造、销售、进口规避技术措施的装置的行为 ,由于威胁到权利人的私力救济 ,也应受到限制 ,这是技术措施保护外延的扩大。
