Over the past few years, a growing attention has been paid to the publish/subscribe (pub/sub) communication paradigm which has become the best model for disseminating information (also called events) through distributed systems on wide-area networks. There are many ways to implement the publish/subscribe system architecture. A common way is publishers and subscribers interact through one or more agents called broker. Broker has to store and management subscriptions, match messages, and efficiently delivery messages to subscribers. It also provides reliability and fault tolerant controlling. Obviously, broker is the most important part of the publish/subscribe system. It is usually required to use a lot of resources such as CPU and memory. In this paper, our publish/subscribe service which implemented by ZeroMQ API could service 10,000 subscribers only cost 3% CPU and 5% memory usage. It is a high performance and low costs publish/subscribe service.

Electronic publishing has currently achieved varying degrees of success in different academic disciplines. This article briefly reviews the exercise of electronic publishing in archaeology and introduces some major efforts in its development. By looking at the challenges and opportunities of these digital projects, the article attempts to pinpoint potential directions of development. An involvement of e-print repositories in supporting archaeological scholarly communication is proposed.

These are the notes I used in my talk as panelist on the technical session/panel titled Competing Information Realities: Digital Libraries, Digital Repositories and the Commons, 2006 Annual Meeting of the American Society for Information Science & Technology, Monday, 6 Nov. 2006 (1:30 - 3:00 pm), Austin, Texas; available in three versions: html, Microsoft Word, and Microsoft Powerpoint (10 slides). I am a scholar, an academic, and the society's journal editor (JASIS&T). I also played agent provocateur in order to represent the publishers' viewpoint.

The publishing of youth-literature in China, which is defined as literature written by and for youths aged 14 to 20, emerged at the beginning of the twenty-first century and quickly became a large scale phenomenon. Over the last decade, it has continued to grow and expand. This study traces the publication of one particular book by drawing on the author???s first hand experience and, more importantly, reveals the inner mechanisms and external social and cultural elements that have shaped this trend in Chinese publishing through careful examination of the publishing histories of two leading youth writers. The author argues that several major elements worked together to make this phenonemon extraordinarily successful: state-owned and private publishers pursuing profit; rebellious or material-oriented youth writers pursuing success; and China???s first only-child generation craving for self-expression and entertainment. These elements were further enhanced by the flourishing of internet and youth popular culture in the new century. This study also reveals that the success of youth-literature publishing comes with consequences for the growth and welfare of Chinese youth. Not only does the pitfalls of commercialization work in publishing for children, but the result has much to do with the history of Chinese children???s literature and the roles that children play in it. By carefully examining controversies, scandals, and debates that have been common in the publishing phenomenon, the author also offers readers a glimpse of the Chinese publishing community and industry, as well as Chinese society during this transitional time.

Many academic decision makers rely on quantified ranking measures to estimate the quality of journal publications. The aim of this study was to map journals in Information Systems (IS) with regard to their topic and their rank and determine whether there is a relationship between the scope of a journal and its rank. The study used content analysis, applying both qualitative and quantitative methods. The results of the analysis show the existence of relationships between the journal rank, the research area, and the type as well as significant differences in ranking on the three lists. The findings illustrate that ranking measures, as indicators for the quality of research published in a journal ought to be considered only in the context of a particular research area and scientific community.
