    LabKey Server: An open source platform for scientific data integration, analysis and collaboration

    <p>Abstract</p> <p>Background</p> <p>Broad-based collaborations are becoming increasingly common among disease researchers. For example, the Global HIV Enterprise has united cross-disciplinary consortia to speed progress towards HIV vaccines through coordinated research across the boundaries of institutions, continents and specialties. New, end-to-end software tools for data and specimen management are necessary to achieve the ambitious goals of such alliances. These tools must enable researchers to organize and integrate heterogeneous data early in the discovery process, standardize processes, gain new insights into pooled data and collaborate securely.</p> <p>Results</p> <p>To meet these needs, we enhanced the LabKey Server platform, formerly known as CPAS. This freely available, open source software is maintained by professional engineers who use commercially proven practices for software development and maintenance. Recent enhancements support: (i) Submitting specimens requests across collaborating organizations (ii) Graphically defining new experimental data types, metadata and wizards for data collection (iii) Transitioning experimental results from a multiplicity of spreadsheets to custom tables in a shared database (iv) Securely organizing, integrating, analyzing, visualizing and sharing diverse data types, from clinical records to specimens to complex assays (v) Interacting dynamically with external data sources (vi) Tracking study participants and cohorts over time (vii) Developing custom interfaces using client libraries (viii) Authoring custom visualizations in a built-in R scripting environment.</p> <p>Diverse research organizations have adopted and adapted LabKey Server, including consortia within the Global HIV Enterprise. Atlas is an installation of LabKey Server that has been tailored to serve these consortia. It is in production use and demonstrates the core capabilities of LabKey Server. Atlas now has over 2,800 active user accounts originating from approximately 36 countries and 350 organizations. It tracks roughly 27,000 assay runs, 860,000 specimen vials and 1,300,000 vial transfers.</p> <p>Conclusions</p> <p>Sharing data, analysis tools and infrastructure can speed the efforts of large research consortia by enhancing efficiency and enabling new insights. The Atlas installation of LabKey Server demonstrates the utility of the LabKey platform for collaborative research. Stable, supported builds of LabKey Server are freely available for download at <url>http://www.labkey.org</url>. Documentation and source code are available under the Apache License 2.0.</p

    Competing Forces Framework of Technology Assimilation: An Investigation into a Group of Mobile Device Users

    Despite evidence that competing forces shape adoption and assimilation of technologies, there is currently no comprehensive model available that explains how such forces impact individually and socially oriented usage of technology. We distinguish between exploration versus exploitation forces and individual versus social forces and posit that these play key roles in shaping assimilation behaviors and usage outcomes. On this basis, we develop the Competing Forces Framework (CFF) of technology assimilation and validate it by analyzing how a group of fifteen iPhone users assimilated mobile services over a period of seven months. In doing so, we draw on data about the antecedent conditions at the time of iPhone adoption, about interactions within the group and its wider social network, and about how individual usage patterns developed over the considered time period. Based on the analysis, we describe and explain how the iPhone was assimilated into the group. As a result, we offer two distinct contributions to the literature. First, we present the CFF to support further investigation of how assimilation behaviors and usage outcomes are shaped as social groups adopt new technologies. Second, we offer new insight into the forces that shape assimilation of mobile devices into a social group of users. At present the analysis is forthcoming
