工作流系统中采用组织结构图实现角色层次

基于角色的存储控制(RBAC)模型在企业级应用环境中非常成功。在大型企业里,怎样进行有效的RBAC管理是一个越来越重要的问题。众所周知,ARBAC97是集中RBAC管理的模型。ARBAC97通过“角色层次”和“约束条件”来管理角色,虽然在某些方面进行得不错,但是这种机制有明显的缺陷。提出在工作流系统中根据需要引入组织结构图来进行角色层次管理。     

Conflict Urbanism,Aleppo: Mapping Urban Damage

One of the oldest continuously inhabited cities on the planet, Aleppo now lies in tatters. This devastation of a designated World Heritage Site is a poignant example of the human and cultural cost of armed conflict – in this case the Syrian Civil War. A project run by the Center for Spatial Research at the Graduate School of Architecture, Planning and Preservation of New York's Columbia University is analysing satellite imagery and reports from the ground to assess the damage and casualties caused there by barrel bombs. Associate Professor Laura Kurgan describes the initiative and its sometimes puzzling findings.     

如何充分发挥党员的先锋模范作用

开展"一转双创"是扎实开展"共建美丽幸福油田"活动的助推器。广大党员只有在实践党的宗旨上发挥共产党员的先锋模范作用,在提高专业技能上发挥共产党员的先锋模范作用,在争创一流业绩上发挥共产党员的先锋模范作用,在道德情操上发挥共产党员的先锋模范作用,才能在工作岗位中建功立业,起到中流砥柱和先锋模范作用,为实现企业内涵式发展,共建和谐企业做出贡献。     

党员分类教育管理的实践与思考

党员分类教育管理,就是正视党员的个体差异,积极探索党员共性要求与个性需要的有机融合,调动和发挥党员的先锋模范作用,进一步增强基层党组织的凝聚力、战斗力。中国石化股份胜利油田分公司清河采油厂南区工作站在这方面进行了有益的尝试,取得了很好的效果,具有一定的推广价值。     

基于企业生命周期的人力资源经理角色分析

文章从企业生命周期的角度,探讨了人力资源经理在不同阶段主要扮演的角色,为企业选拔和培训人力资源经理提供新的视角。将企业生命周期分为创业期、成长期、成熟期和衰退期四个阶段,依据企业生命周期不同阶段的特点及人力资源管理的策略,得出人力资源经理在不同阶段分别主要扮演战略合作伙伴、HRM专家、员工激励者、变革推动者的角色。

如何进一步发挥女工组织在和谐企业建设中的职能作用

在当代社会体系中,女性是维系家庭、企业、社会和谐的重要力量,构建和谐企业,同样离不开广大女职工的全力参与。她们具有不可替代的职能优势、不可低估的组织优势,还有传统的阵地优势。这些优势有利于她们在企业中,强化职能意识,健全维权机制;树立品牌意识,提升服务品质;丰富活动内涵,展示时代风采,为企业和谐有效发展做出应有贡献。     

可集成制造执行系统(I-MES)冲突消解研究

首先构造了基于多Agent的I—MES体系结构，并针对I—MES中最常见的资源冲突问题，建立了多Agent合作的冲突消解模型，同时将PERT／CPM方法引入到I—MES系统的冲突消解过程，对所发生的冲突进行分类，并以非关键路径冲突为例，讨论多代理合作的冲突消解策略，并给出基于KQML—BDI的协商协议。最后开发了该原型系统，以验证冲突消解策略和协商协议。     

Quantifying Whitewater Recreation Opportunities in Cataract Canyon of the Colorado River,Utah: Aggregating Acceptable Flows and Hydrologic Data to Identify Boatable Days

The structural norm approach was combined with the Potential for Conflict Index to define recreation streamflow needs for the Colorado River in Utah and Colorado. An online survey was completed by 128 commercial and non‐commercial boaters, who evaluated a range of flows for whitewater boating. For the Cataract Canyon reach, respondents rated the quality of their recreation experience of specific flows, describing the quality of boating opportunities across the full range of historical streamflows. Ranges for both acceptable and optimum flows were defined, as well as thresholds for unacceptable flows. These ranges were then evaluated against historical hydrologic records to quantify the timing, frequency, and duration of days when defined whitewater flows exist across different year types (i.e. average boatable days). Results indicated that on average, a total of 257 boatable days existed in dry years, and 353 total boatable days occurred in dry‐typical years. In wet and wet‐typical years, 362 and 365 total boatable days respectively, occurred on average. Results of the boatable days' analysis indicated that over the 23‐year period of record, whitewater boating opportunities occurred nearly every day of the year in all but the driest year types. Results from this study provide resource managers with information which can be used in the development of annual operating plans for the Colorado River Basin and help managers understand how changes in flow impact the quality of recreational opportunities. This application demonstrates the value of analysing boatable days on any river where recreation management is a priority. Copyright © 2016 John Wiley & Sons, Ltd.     

主题图融合技术研究综述

主题图在信息资源上层构建了一个结构化的语义网,提供了一个良好的语义模型,可以弥补web 2.0在应用上存在的语义缺陷,而主题图融合作为主题图的重要研究内容,是将分布式环境下同一领域内分散的局部主题图合并为一个全局主题图,实现Web信息的有效组织和管理以及信息的集成与共享.归纳总结了主题图融合的处理过程,分析评价了主题图融合中的难点--主题图的相似性算法,并对融合的原则和算法进行了分析总结,明确了高相似度主题融合的过程.此外,在分析主题图融合冲突的基础上,提出了主题图融合冲突检测与消除的整体设计方案,并将主题图的动态更新进行了阶段划分,最后指出了主题图融合未来的研究方向.
