A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.     

Virtual Communities of Practice in Social Group Work Education

Virtual communities of practice are an international phenomenon in social work around the world. However, they are rare in social work in the United States. This article describes an online community, the Social Group Work Commons, designed to complement courses in social group work. Using Web 2.0 Internet tools, such as blogs, discussion boards, and chats, the developers employed group work skills to help students establish a vehicle for mutual support as students struggled to integrate course content in their field placements. Examples from course blogs indicate students became increasingly intimate in their online exchanges over time and readily provided each other support in applying course content in their practice.

浅谈数据挖掘与图书管理

随着数据库技术的不断发展及数据库管理系统的广泛应用,数据库中存储的数据量急剧增大,在大量的数据背后隐藏着许多重要的信息,如果能把这些信息从数据库中抽取出来,将为公司创造很多潜在的利润,而这种从海量数据库中挖掘信息的技术,就称之为数据挖掘.从网络技术角度来看,数字图书馆与其它WEB信息源没有两样,它们都是建立在INTERNET上的信息站点.数字图书馆是一个标准的电子信息基础设施,它采用分布式数据存储,用户可以通过各种链接和操作在一个较大的地域范围内搜索和检索出自己所需的信息,而且整个操作对用户是开放的.

New Media and Social Networks: Considerations from Clients in Addictions Treatment

Web-based (2.0) media will play an increasing role in substance abuse treatment. Two focus groups identified initial barriers and potential uses within a population living below the median income. Client suggestions included using different approaches to service delivery based on a person's access to web 2.0 media. Preliminary results indicated that contrary to the staff members' opinions, the majority of clients appeared to have sufficient Internet access and the requisite social networking skills in order to participate in online interventions. Future research should focus on using games as a potential mode of online service delivery, on the potential of the various forms of social networking, and whether classism exists between client and staff perceptions.     

人肉搜索现象探析

近年来,人肉搜索已成为网络上的一个热门话题.它的兴起首先是由于Web2.0技术的发展为网民的交流互动提供了技术支持,从而实现了网络信息的海量化发展;其次是由沉默的螺旋所形成的舆论氛围吸引了大量网民的参加.人肉搜索的特点在于它体现了一种庶民"狂欢",在道德面纱的遮掩下广大网民通过人肉搜索不仅满足了多种心理诉求,同时也找到了一种群体宣泄的路径.由于人肉搜索在发展过程中出现了一系列的问题,这就需要我们不断提高网民的媒介素养.
