Catalogers often find it difficult to explain to other librarians what we do. This article offers some suggestions. Elizabeth J.

The data itself is meaningless without understanding of what the numbers mean. This fall 2009 ICAIA presentation examines 5 different vehicles across 5 different operating conditions measured with 5 different scan tools in an investigation of "normal" parameters. Matt Dixon http://opensiuc.lib.siu.edu/pn_wp/36 http://opensiuc.lib.siu.edu/pn_wp/36 Thu, 15 Oct 2009 10:13:20 PDT This paper uses the methods of social network analysis to discover the structural patterns of cooperation that arose in response to a global traditional security problem. It does this by mapping compulsory and institutional power relations (Barnett and Duvall 2005) among actors responding to the proliferation of nuclear weapons since the end of the Cold War. For the institutional power measure, I use treaty and international agreement membership; and for the compulsory power measure, I use contractual obligations for nuclear expertise, materials, and technology. By mapping the relationships at the system level of world politics, including individual states as well as intergovernmental organizations (IGOs), transnational nongovernmental organizations (NGOs), and transnational corporations (TNCs), this paper finds a third relation among these actors, namely, structural power. It also demonstrates how a network approach to the constitution of system level world politics can produce knowledge not available to traditional methods. Annelies Z.

Omar Trinidad http://opensiuc.lib.siu.edu/morris_articles/31 http://opensiuc.lib.siu.edu/morris_articles/31 Thu, 08 Oct 2009 14:10:47 PDT In this study, the researchers submitted a music score approval plan survey to all ARL libraries. Two surveys were created, one for libraries with music score approval plans, one for those without. Forty-four surveys were returned. The authors' purpose was to analyze and discuss the survey results, incorporating elements of the scholarly work preceding this study. Discussions, roundtables, and listservs participated in by music librarians over the years formed the basis of the topic at hand. The goal was to ascertain whether these discussions and underlying assumptions of approval plans held true to the real world. Elizabeth J. Cox http://opensiuc.lib.siu.edu/dissertations/2 http://opensiuc.lib.siu.edu/dissertations/2 Mon, 05 Oct 2009 08:33:01 PDT An organizational strategy to develop software has appeared in the market. Organizations release software source code open and hope to attract volunteers to improve their software, forming what we call an open source project. Examples of organizations that have used this strategy include IBM (Eclipse), SAP (Netweaver) and Mozilla (Thunderbird). Moreover, thousands of these projects have been created as a consequence of the growing amount of software source code released by individuals. This expressive phenomenon deserves attention for its sudden appearance, newness and usefulness to public and private organizations.To explain the dynamics of open source projects, this research theoretically identified and empirically analyzed a construct - attractiveness - found crucial to them due to its influence on how they are populated and operate, subsequently impacting the qualities of the software produced and of the support provided. Both attractiveness' causes and consequences were put under scrutiny, as well as its indicators.On the side of the consequences, it was theoretically proposed and empirically tested whether the attractiveness of these projects affects their levels of activeness, efficiency, likelihood of task completion, and time for task completion, though not linearly, as task complexity could moderate the relationships between them. Also, it was argued at the theoretical level that activeness, efficiency, likelihood of task completion, and time for task completion mediate the relationship between attractiveness and software/support quality.On the side of attractiveness' causes, it was proposed and tested that five open software projects' characteristics (license type, intended audience, type of project and project's life-cycle stage) impact attractiveness directly. Additionally, these projects' characteristics were argued to influence projects' levels of activeness, efficiency, likelihood of task completion, and time for task completion (and so an empirical evaluation of their associations was performed).The empirical tests of all these relationships between constructs were carried out using Structural Equation Modeling with Maximum Likelihood on three samples of over 4,600 projects each, collected from the largest repository of open source software, Sourceforge.net (a repeated cross-sectional approach). The results confirmed the importance of attractiveness, suggesting a direct influence on projects' dynamics, as opposed to the moderated-by-task complexity indirect paths first proposed. Furthermore, all four projects' characteristics studied were found to significantly influence projects' attractiveness, activeness, efficiency, likelihood of task completion, and time for task completion (with the exception of license type and time for task completion).Besides providing a statistical test of these propositions, this study discovered the direction of the influence of each project characteristic on projects' attractiveness, activeness, efficiency, likelihood of task completion and time for task completion. Lastly, conclusions, limitations, and future directions are discussed based on these findings. Carlos D. Santos Jr.
