Signatures of Quark-Gluon-Plasma formation in high energy heavy-ion collisions: A critical review

A critical review on signatures of Quark-Gluon-Plasma formation is given and the current (1998) experimental status is discussed. After giving an introduction to the properties of QCD matter in both, equilibrium- and non-equilibrium theories, we focus on observables which may yield experimental evidence for QGP formation. For each individual observable the discussion is divided into three sections: first the connection between the respective observable and QGP formation in terms of the underlying theoretical concepts is given, then the relevant experimental results are reviewed and finally the current status concerning the interpretation of both, theory and experiment, is discussed. A comprehensive summary including an outlook towards RHIC is given in the final section.Comment: Topical review, submitted to Journal of Physics G: 68 pages, including 39 figures (revised version: only minor modifications, some references added

Manuscript Architect: a Web application for scientific writing in virtual interdisciplinary groups

BACKGROUND: Although scientific writing plays a central role in the communication of clinical research findings and consumes a significant amount of time from clinical researchers, few Web applications have been designed to systematically improve the writing process. This application had as its main objective the separation of the multiple tasks associated with scientific writing into smaller components. It was also aimed at providing a mechanism where sections of the manuscript (text blocks) could be assigned to different specialists. Manuscript Architect was built using Java language in conjunction with the classic lifecycle development method. The interface was designed for simplicity and economy of movements. Manuscripts are divided into multiple text blocks that can be assigned to different co-authors by the first author. Each text block contains notes to guide co-authors regarding the central focus of each text block, previous examples, and an additional field for translation when the initial text is written in a language different from the one used by the target journal. Usability was evaluated using formal usability tests and field observations. RESULTS: The application presented excellent usability and integration with the regular writing habits of experienced researchers. Workshops were developed to train novice researchers, presenting an accelerated learning curve. The application has been used in over 20 different scientific articles and grant proposals. CONCLUSION: The current version of Manuscript Architect has proven to be very useful in the writing of multiple scientific texts, suggesting that virtual writing by interdisciplinary groups is an effective manner of scientific writing when interdisciplinary work is required

Mapping Diversity in Milan - Historical Approaches to Urban Immigration

An historical and spatial approach is crucial to the understanding of any city. Waves of immigration and population movements from different sources have constructed the cultural mix of this financial, industrial and market city over time. To focus just on the new foreign immigration into Milan over the last 25 years or so risks omitting the deep historical fissures created by previous (and bigger) waves of population movements the traces left by these populations in the urban fabric and their role in subjective experience. Moreover, the historical and spatial comparison of various types and moments of population movement can help us to understand the changes to this city at macro and micro-levels. This paper uses a mixture of approaches in order to understand and map diversity in Milan, its province and its region. It is intended as a discussion paper to be looked at in conjunction with the work and arguments laid out in other research projects and published work. Methodologies used in this paper range from straightforward historical research (using documents and archives) to photography, micro-history (the examination of one small area in this case one housing block) and oral historical interviews
