The Improvement Of Financial Performance Evaluation System Of County Power Enterprises [PDF]

open access: yes, 2014
县级电网企业(以下简称“县公司”)作为电网运营的重要组成部分,是电力供应、销售的最后环节。县公司发展水平的高低和经营管理的好坏不仅关系到省公司的发展和国家电网公司“一强三优”现代公司发展目标的实现,而且直接关系着浙江地方经济的繁荣发展与社会的和谐稳定。 本文研究内容以浙江省电力公司(以下简称“浙江公司”)下属典型县公司为考察研究的主要对象,在比较研究国内外有关企业绩效评价理论基础上,结合电力行业自身行业特点和电网企业发展状况,在融合借鉴国资委对央企考核指标体系与国网公司对各省公司考核指标体系的基础上 ...

How much biotic nativeness matters across human demographic groups

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Design and Implementation of the Monitoring and Early Warning System for a City’s Real Estate Market [PDF]

open access: yes, 2015
自我国城镇房地产制度改革以来,商品房市场化进程加快。在商品房市场化进程加速背景下,房地产市场的繁荣成为国家经济快速增长的重要推动力量,也是我国国民经济的重要组成部分,从国民经济整体看,房地产开发投资占全社会固定资产投资比重较大是其要组成部分,从国民经济结构看,根据权威部门统计房地产行业对国民经济近四十个行业都有拉动影响。毫无疑问,房地产市场的波动对国民经济会产生较大影响。在这种情形下,如何把握房地产市场各个方面的运行态势,监测、预判市场运行异常态势,实现对房地产市场出现异常运行情况的预警就显得十分有必要。

基于综合赋权的电磁环网开环方案评价方法研究

open access: yesGaoya dianqi, 2023
针对目前电磁环网开环方案综合评价方法主观性过强,评估指标体系不完善问题。文中提出了一种基于综合赋权的电磁环网开环方案评价方法。首先,分析电磁环网开环原则及机理;在此基础上,综合考虑系统安全稳定性、限流效果等因素,构建开环方案综合评价指标体系;然后利用层次分析法与变异系数法求出主、客观权重系数,进而通过综合评价方法计算得到评估开环方案优劣的综合评价指标;最后通过39节点标准算例、湖南省某地区实际电网算例,结合电力系统分析综合程序(PSASP)仿真分析,验证了文中所提方法的有效性与在实际电网中应用的合理性。

Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.
ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.

The Research on designing performance evaluation indexes system for Fujian W Private hospital [PDF]

open access: yes, 2016
国内民营医院的发展一直面临着管理混乱、能力缺失、没有优势特色等一系列的问题,加上政策环境不利,使得民营医院难以得到长足发展。近几年,政府对社会办医越来越重视,并颁布了一系列政策,使得民营医院迎来了前所未有的机遇。找准战略定位,提升管理效率是民营医院抓住政策机遇寻求发展的两盏明灯,而其中符合医院战略定位的绩效评价体系是将战略落地并进行有效管理的重要手段。本文在分析福建W医院的内外部环境,已确定W医院发展战略的前提下,构建了基于平衡计分卡的绩效评价指标体系,从医院、科室、岗位三个层面分析了考核指标的建立 ...
