反射技术与软件的适应性

介绍了反射技术的发展历史，并分析了反射的概念。以Adapter Pattern为例，讨论了如何用反射技术实现设计模式。在此基础上给出了具有反射结构的适配器模式，通过引进角色对象和协作对象，进一步提出了具有并发控制功能和适应性的反射软件结构。     

A database model for object dynamics

To effectively model complex applications in which constantly changing situations can be represented, a database system must be able to support the runtime specification of structural and behavioral nuances for objects on an individual or group basis. This paper introduces the role mechanism as an extension of object-oriented databases to support unanticipated behavioral oscillations for objects that may attain many types and share a single object identity. A role refers to the ability to represent object dynamics by seamlessly integrating idiosyncratic behavior, possibly in response to external events, with pre-existing object behavior specified at instance creation time. In this manner, the same object can simultaneously be an instance of different classes which symbolize the different roles that this object assumes. The role concept and its underlying linguistic scheme simplify the design requirements of complex applications that need to create and manipulate dynamic objects. Edited by D.

一种面向信息系统的通用角色集成管理方法研究

角色的概念普遍存在于信息系统中,本文从业务管理、用户个性化信息管理、知识管理和角色关系管理等四个方面对角色进行综合集成和管理,并给出相应的形式化描述.对角色理论、建模和实际应用进行了较充分的研究,这些研究对普遍采用角色概念的信息系统的设计和实现都具有一定的指导意义和现实意义.     

一种电子商务安全解决方案的研究与实现

随着计算机技术的发展，电子商务逐渐显示出其相对于传统商秀活动的巨大优势，诸如电子支付、电子交易等类型的商务活动形式给人们带来的便利足以体现电子商务对人们生活的巨大影响。但是由于lnternet是一个、开放的系统、昕以重要数据在网上传输的安全性成为发展电子商务的重要环节．这个环节出错，将会使电子商务失去意义，文中挖掘丁电子商务中应该解决的若干重要问题，设计了公开密钥基础设施、JavaBean、基于角色的访问控制三者结合的整体解决方案，加强了电子商务的安全性。该方法已经在笔者参加的福建省卫生厅药品招标采购系统的开发中得到应用，并取得了较好的效果。     

基于角色的权限分配和管理中的方法

对当前权限系统设计过程中的主要权限分配方法进行介绍和比较，发现它们各自的灵活性和适用性不一样，并着重讨论了基于角色的访问控制模块，分析了RBAC模型中用户、角色与操作权限之间的关系。在此基础上，提出了一种应用于办公自动化系统中较安全的操作权限的实现思想，通过分析提出了五种可行的操作权限分配过程中的解决方法，并评价了各自的优点与不足。

Intra-BLA or Intra-NAc Infusions of the Dopamine D? Receptor Partial Agonist, BP 897, Block Intra-NAc Amphetamine Conditioned Activity.

Recent studies have shown that both systemic and intra-nucleus accumbens (NAc) or intra-amygdala administration of dopamine D? receptor ligands modulate reward-related learning. A previous study (H. Aujla, H. Sokoloff, & R. J. Beninger. 2002) showed that systemic administration of the partial dopamine D? receptor agonist BP 897 selectively blocked the expression, but not the acquisition, of amphetamine-conditioned activity. This suggested the hypothesis that intra-NAc or intra-basolateral amygdala (BLA) BP 897 would attenuate the expression, but not the acquisition, of amphetamine-conditioned activity. Rats were habituated to activity-monitoring chambers for 5 days, for 1 hr each day. Conditioning occurred on the next 3 days, followed by a single 1-hr test session. Intra-NAc or intra-BLA infusions of BP 897 during test, but not during conditioning, attenuated intra-NAc amphetamine conditioned activity. Results indicate that the ability of BP 897 to attenuate the expression of conditioned activity is mediated in part by the NAc and BLA.

Links Between Sex-Typed Time Use in Middle Childhood and Gender Development in Early Adolescence.

The authors studied sex-typing in the kinds (e.g., sports, handicrafts) and social contexts (same- vs. other-sex companions) of children's free time activities, and the links between sex-typed activities and gender development over 2 years. Participants were 200 White, working- and middle-class children (103 girls, 97 boys; mean age = 10.86 years). In annual home interviews, children rated their self-esteem, gender role attitudes and sex-typed personality qualities, academic interests, and school grades. During 7 nightly phone interviews each year, children reported on their activities. Boys were more sex-typed than girls in their peer activities, and children were least sex-typed in their activities with siblings. Sex-typed activities in middle childhood predicted individual differences in gender development in early adolescence (PsycINFO Database Record (c) 2010 APA, all rights reserved)
