面对迅速发展的铁路运输事业,中国铁路安全法律制度还存在一些不足,亟需完善。美国联邦铁路安全法律制度在改善其铁路安全状况方面发挥了重要作用。它的主要特点是:明确安全为最高优先事项、重视铁路安全规制机构的建设、运用多元的规制工具和执行手段、设置必要的行政程序。美国经验对我国完善铁路安全立法、加强铁路安全行政组织建设、优化行政行为形式和改进行政程序具有借鉴价值。 相似文献

中央银行实施货币政策的过程就是运用操作工具实现政策目标的过程,为更好地实现既定的货币政策目标,中央银行应该依据一定的基准选择操作工具。中央银行选择操作工具的基准包括理论基准和实证基准,其中,前者包括外在性基准和内在性基准。内在性基准是其日常操作中最重要的选择基准,它又有主动性基准、微调性基准、信号功能基准、时效性基准和可操作性基准等内容。 相似文献

There is little documentation in the literature of how to conduct a data audit of laboratory research. The purpose of such an audit is to verify the extent to which the published data agree with the corresponding laboratory notebook data and whether the data thus examined appear to be sufficient to justify the published conclusions. A case study is presented, which demonstrates a step by step approach towards conducting a data audit of a published research study. 相似文献

In this paper, we study the M-estimators in the case that λF:(β)=EF:(φ(Z,β))=0 has more than one solution, We show that the numerical iterative procedures converge and that the resulting estimators are consistent and asymptotically normal. We apply them to the non-linear regression models, and then, we find an optimal M-estimate among those that have bounded gross error sensitivity. 相似文献

We describe a method of computing the cumulative distribution function of the maximum and minimum cell frequencies in sampling distributions commonly encountered in the analysis of categorical data.The procedure is efficient for exact or approximate calculation in both homogeneous and non-homogeneous cases, is non-recursive, and does not require Dirichlet integrals.Some related statistical problems are also discussed. 相似文献

Siting Noxious Facilities: A Test of the Facility Siting Credo 总被引:2,自引:0,他引:2
Over the past decade it has become increasingly difficult to site noxious facilities, despite the fact that there is a growing need to do so. To address this problem, a set of guidelines for a fairer, wiser, and more workable siting process—the Facility Siting Credo—was developed during a National Facility Siting Workshop in 1990. This paper presents an empirical test of these guidelines. A questionnaire based on the Credo was completed by stakeholders in 29 waste facility siting cases, both successful and unsuccessful, across the United States and Canada. Using an independent determination of outcome (success), a preliminary ranking of the importance of various Credo principles was obtained. The data reveal that establishing trust between the developer and host community is an important factor in facilitating the siting process. The siting process is most likely to be successful when the community perceives the facility design to be appropriate and to satisfy its needs. Public participation also is seen to be an important process variable, particularly if it encourages a view that the facility best meets community needs. Moreover, a siting process where communities volunteer to host facilities is an approach that holds promise for meeting many of these key success criteria. 相似文献

This paper reviews global and multiple tests for the combination ofn hypotheses using the orderedp-values of then individual tests. In 1987, Röhmel and Streitberg presented a general method to construct global level α tests based on orderedp-values when there exists no prior knowledge regarding the joint distribution of the corresponding test statistics. In the case of independent test statistics, construction of global tests is available by means of recursive formulae presented by Bicher (1989), Kornatz (1994) and Finner and Roters (1994). Multiple test procedures can be developed by applying the closed test principle using these global tests as building blocks. Liu (1996) proposed representing closed tests by means of “critical matrices” which contain the critical values of the global tests. Within the framework of these theoretical concepts, well-known global tests and multiple test procedures are classified and the relationships between the different tests are characterised. 相似文献

《不动产登记暂行条例》按照《物权法》的规定,实行不动产统一登记制度,改变我国当前不动产“多头登记”的现状,有利于界定不动产归属,维护交易安全。总则部分关于登记范围的规定遗漏了探矿权、采矿权、取水权这三种重要的权利,且没有在全国范围内确定唯一的不动产登记机构,故没有真正实现完全意义上的不动产统一登记;暂行条例首次规定了不动产登记薄的设置、保管、查阅等内容,但是依然欠缺登记簿法律效力的规定,没有彻底地贯彻物权公示公信原则;登记程序亦没有和《物权法》的程序性规定实现有效整合。登记机构对于登记申请的审查义务的规定明确、具体,在明晰审查义务的基础上,援引《物权法》的规定确定登记错误时登记机构的赔偿责任,较为合理。 相似文献
