政府能力高低程度决定了行政组织产出的质量和数量,政府能力绩效评估就是根据行政组织的管理效率、效益、能力、服务质量、公共责任和顾客满意程度等方面的评价,对行政组织在管理过程中的投入、产出、政策或规定执行、中长期目标完成的... 政府能力高低程度决定了行政组织产出的质量和数量,政府能力绩效评估就是根据行政组织的管理效率、效益、能力、服务质量、公共责任和顾客满意程度等方面的评价,对行政组织在管理过程中的投入、产出、政策或规定执行、中长期目标完成的结果等能力绩效进行评定和划分等级。对政府能力开展绩效评估有着三方面的理论依据,而在实践中需要建构一种基于绩效评估过程的有利于政府能力提升的组织运行模式,这种模式的运行能推动政府以绩效评估为核心的行政绩效的变革。 展开更多

Some methods employed have many shortcomings. For example, they cannot make the reliability adequately explicable. Therefore, a mathematical tool, the unascertained measure, was introduced. First, the basic knowledge of the unascertained sets was introduced briefly. Second, the unascertained measure was defined and credible identification was set up. The method has been introduced into the fields for safety assessment of a jacket loadout procedure. Engineering practices showed that it can complete the safety assessment systematically and scientifically without any assumption. The work should have significance in theory and practice for offshore engineering. 展开更多

Based on 18 global climate models' simulations of the 20th century climate, a set of experiments within phase five of the Coupled Model Inter-comparison Project (CMIP5), the performances of simulating the present climate over China are assessed. Compared with observations, models can capture the dominant features of the geographic distributions of temperature and precipitation during 1961-2005. For the temporal changes of temperature, models appear to have a good performance on reproducing the warming tendency but show limited skills for precipitation. For the regional mean temperature and precipitation over the whole of China, most models underestimate the actual temperature and overestimate precipitation. Concerning the standard deviations of simulations by the 18 models, they are larger for temperature in the western part of China, while the standard deviations are larger for precipitation in the South. 展开更多

The MBC mode is for new generation block cipher algorithms. Its speed is about 13% faster than that of the authentication modes in common use (for example, cipher block chaining-message authentication code mode). The dependence test results meet the requirement. The MBC mode is complete; its degree of ava-lanche effect is about 0.9993; its degree of strict avalanche criterion is 0.992 or so. The frequency test results indicate that the output generated by the MBC mode has uniformity. The binary matrix rank test results imply that it is linear independent among disjoint sub-matrices of the output. Maurer’s universal statistical test results show that the output could be significantly compressed without loss of information. Run test, spectral test, non-overlapping template matching test, overlapping template matching test, Lempel-Ziv compression test, linear complexity test, serial test, approximate entropy test, cumulative sums test, random excursions test and random excursions variant test results fulfill the requirements of all. Therefore the MBC mode has good pseudo-randomness. Thus the security of MBC mode is verified by the way of statistical evaluation. 展开更多
