Over the past decade Identity Management has become a central theme in information technology, policy, and administration
in the public and private sectors. In these contexts the term ‘Identity Management’ is used primarily to refer to ways and
methods of dealing with registration and authorization issues regarding persons in organizational and service-oriented domains.
Especially due to the growing range of choices and options for, and the enhanced autonomy and rights of, employees, citizens,
and customers, there is a growing demand for systems that enable the regulation of rights, duties, responsibilities, entitlements
and access of innumerable people simultaneously. ‘Identity Management’ or ‘Identity Management Systems’ have become important
headings under which such systems are designed and implemented. But there is another meaning of the term ‘identity management’,
which is clearly related and which has gained currency. This second construal refers to the need to manage our moral identities
and our identity related information. This paper explores the relation between the management of our (moral) identities and
‘Identity Management’ as conceptualized in IT discourse. 相似文献

江泽民在领导中国人民进行现代化建设过程中十分重视反腐败工作,并作出了一系列重要论述,从而发展了邓小平的反腐败思想。具体体现在三个方面：（１）深刻地阐述了反腐败的重大意义;（２）科学地分析了腐败现象的成因;（３）果断地作出了反腐败的整体部署。这些对于指导现阶段的反腐败斗争无疑具有重大的指导意义。 相似文献

The study presented here will examine the connection between teaching and development, focusing in particular on how children solve “missing addend” story problems. Vygotsky’s theory of development will serve as the framework. Ordinarily, when second graders are forced to solve a problem of this type by choosing an arithmetic operation (+ or ?), half of them fail. The most frequent error is choosing addition. The subjects in the experiment presented here were second graders who had always been given the opportunity to use objects or drawings to “act out” (model) the actions expressed in the problem statament. They had never been in the above “forced-choice” situation. Moreover, they had been taught to use a “forward strategy” to solve subtraction problems like 42–36 (to get from 36 to 40, it takes 4; and then to get to 42, it takes 2 more) and a “backward strategy” for subtraction problems like 42–6. When given the following missing-addend problem: “Pierre has 63 pieces of candy and paul has 4. Paul wants to have the same number of pieces as Pierre. How many pieces of candy must Paul buy?” none of these children performed an addition, approximately half did a subtraction, and the others succeeded by using a breakdown strategy or a drawing. The overall success rate was 92%. The results obtained suggest a way of operationalizing the notion of “zone of proximal development” for problem solving of this type. 相似文献

集装箱堆场分配与自动化装载小车路径联合优化 总被引：1，自引：0，他引：1
为研究自动化装载小车(Automated Lifted Vehicle,ALV)在自动化集装箱码头的作业状况,首先考虑ALV自行装卸集装箱的能力,其次考虑卸船集装箱的堆场分配与ALV的路径联合优化问题,以每个集装箱在时间窗内完成装卸任务为目标建立混合整数规划模型.最后通过比较不同实验条件下求出的最优目标延迟时间和计算机运行时间,得出整个操作过程中ALV数、集装箱数和堆场子箱区数这三者之间的关系.数值实验表明:当集装箱数和ALV数一定时,随着装卸箱比例的增大,目标延迟时间和模型运算时间呈相同的变化趋势,即在既有装船箱又有卸船箱时应优先分配ALV满足装船箱的运输;当集装箱数一定时,随着ALV数的增加,目标延迟时间和模型运算时间逐步减少;当ALV数一定时,随集装箱数的增加,目标延迟时间和模型运算时间增加. 相似文献
