基于Serv-U的FTP权限管理

分析目前FTP用户管理中由系统管理员集中分配权限产生的弊端：用户权限较少；当用户较多、权限变更频繁时难于管理。提出在FTP用户管理中分配权限的受限再分配机制，从而达到分级管理用户权限、减轻系统管理员工作量的目的。实现一个基于Serv-U扩展接口的FTP用户管理应用系统。

统一用户管理和身份认证服务的设计与实现

用户管理、身份认证和权限控制在每个应用系统中都占有很重要的地位。但是，各个应用系统使用各自的用户管理，会带来使用上的不便、管理上的复杂、资源上的浪费以及安全上的隐患。因此，我们在对现有的技术进行分析、研究后，设计了北京大学统一用户系统。该系统采用Java 2 Platform，Enterprise Edition(J2EE)技术，能够提供统一、集中、有效的基于角色的用户管理、权限管理、资源管理，并且能够提供支持单点登录的用户身份认证服务。文中对系统的整体设计思想、体系结构以及实现策略做了论述。

轻松管理Moodle用户

Moodle的用户管理一直是个令教师比较头疼的问题。在实际操作中，有的教师甚至让学生直接以访客身份登录课程，避开用户管理这一问题，但这种方法没有针对性，教师无法了解学生的情况。此外，系统存在运行速度慢，并发率低的问题。访客越多，速度越慢，所以把用户管理起来是十分必要的。在从Moodle1．53版本到1．83版本的实践过程中，笔者积累了这方面的一些经验，愿与大家分享（本文以1．83版本为例）。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead.

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
