陕西省地勘局地勘单位企业化经营的作法

本文介绍了陕西省地勘局、队两个层次企业化经营的作法.局级主要是实行"一院两公司",组建的公司按企业机制运作;队级主要实行模拟股份合作制改制、剥离后勤服务部门、精减机构等改革.同时介绍了相应的配套改革措施,如每年从地勘费中切出一块作为资本金注入,实行全员聘用制和按劳按资相结合的分配制度等.     

Using GIS tools to estimate CO2 emissions related to the accessibility of large retail stores in the Oulu region, Finland

Everyday traffic accounts for a significant share of overall greenhouse gas emissions, in particular carbon dioxide (CO₂). While several solutions have been proposed for decreasing the emissions, a new kind of land use planning is required in order to achieve long-term effects. This study focuses on the effect of large retail store locations in the urban structure on overall CO₂ emissions, by using the Oulu region, Finland, as a case study. The aim was to utilize GIS tools to assess store locations in terms of CO₂ emissions from private cars used for consumer traffic. In this case, not only are the locations of the existing and planned retail units investigated with respect to population distribution and car ownership, but the analysis is also carried out by regarding any location within the study area as a hypothetical site for a large retail unit. According to the applied method, CO₂ values are lowest near the centre of the studied region, the region with the highest population density, although the city centre itself did not turn out to be the most optimal location for a retail store in terms of CO₂ emissions. Nevertheless, by generally reducing trip length, a compact urban structure is an important way of achieving long-term cuts in CO₂ emissions.     

大型贯流式机组设计及运行问题浅析

贯流式机组以其优良的水力特性和显著的经济效益倍受广大水电开发者的青睐,贯流机组的单机容量不断增大,同时其应用水头范围向高水头和超低水头两边延伸,但是由于该类机组发展的时间较短,在发展过程中存在一些问题,究其原因包含设计、制造、安装、运行等各方面问题,有的问题已经严重影响到机组的稳定运行,文章通过对近十年来设计或考察过的贯流机组存在的一些普遍性问题进行探讨,希望能够对贯流机组的发展提供有益的参考。

我国机关事业单位养老保险制度改革探讨

在同一社会制度下并存不同的养老保险制度，这不利于社会的稳定，不利于机关事业单位用人制度的改革，不利于社会保障整体功能的发挥，也不利于市场经济的发展。因此，改革机关事业单位养老保险制度，建立统一的城镇职工养老保险制度，是完善社会主义市场经济体制的迫切要求。     

Estimation from two-stage unequal probability sampling with missing units

A formula is presented for an unbiased estimator for the variance of an unbiased estimator of a survey population total as well as for an unbiased estimator of its variance based on sampling in two-stages following Rao et al. J Roy Stat Soc B 24: 482–491 (1962) scheme in both stages when the originally selected units in both stages cannot be fully covered in the survey but are to be randomly sub-sampled. The development is helpful to tackle non-responses if assumed to have occurred at random in either or both the stages     

科技投入产出视角下山东省科研非企业科技活动单位创新能力分析

为了探索建立科研非企业科技活动单位创新能力评价方案，正确评价山东各地市的科技创新实力，对山东省科研非企业科技活动单位的创新能力进行评价，构建了包含科技创新资源和科研产出两个层次10个指标的创新水平评价指标体系。通过对山东省各地市科研非企业科技活动单位的科技创新资源和科研产出及总体数据分别进行因子分析，得出各地市创新水平的综合得分。根据评价得分，分析不足，提出加强山东省各地市科研非企业科技活动单位创新能力的对策建议。
