Communication is essential for the success of a software project: Requirements need to be elicited, documented, and design decisions must be spread within a software development team. However, there are symptoms indicating weakening communication, inappropriate communication media, or unsatisfactory information flow. The TeamFLOW project is an interdisciplinary endeavor among software engineers and psychologists, investigating relationships between team spirit, communication behavior, and several aspects of success. By understanding those relationships better, we want to enable project leaders and teams to anticipate problems earlier, by observing key indicators. Prediction and warnings based on communication and team spirit can help keeping a project on track.
In this talk, the main assumptions and hypotheses of the TeamFLOW project are described; key findings are presented, and the research methodology is discussed. TeamFLOW unfolds in two phases: During the current phase, a rather large set of homogenous and comparable student projects is used. Due to the similarity of most variables, the impact of varying communication structures and behaviors can be recognized better. Research methods of software engineers and psychologists needed to be combined and adjusted to the specific situation. Some of the findings will be presented and discussed, such as the role of more or less indirect communication; for example, the concept of “FLOW distance” captures the idea that some teams seem to drift apart, with detrimental consequences for their projects. In the second phase, finding from the homogenous set of projects will be extended towards bigger, more distributed or agile projects with different communication structures.

Social media and online communities provide organizations with new opportunities to support their business-related functions. Despite their various benefits, social media technologies present two important challenges for sense-making. First, online discourse is plagued by incoherent, intertwined conversations that are often difficult to comprehend. Moreover, organizations are increasingly interested in understanding social media participants’ actions and intentions; however, existing text analytics tools mostly focus on the semantic dimension of language. The Language-Action Perspective (LAP) emphasizes pragmatics; not what people say, but rather, what they do with language. Adopting the design science paradigm, we propose a LAP-based text analytics framework to support sense-making in online discourse. The proposed framework is specifically intended to address the two aforementioned challenges associated with sense-making in online discourse: the need for greater coherence and better understanding of actions. We rigorously evaluate a system developed based on the framework in a series of experiments on a test bed encompassing social media data from multiple channels and industries. The results demonstrate the utility of each individual component of the system, and its underlying framework, in comparison with existing benchmark methods. Furthermore, the results of a user experiment involving hundreds of practitioners, and a four-month field experiment in a large organization, underscore the enhanced sense-making capabilities afforded by text analytics grounded in LAP principles. The results have important implications for online sense-making and social media analytics.

Andean textiles are products of one of the richest, oldest and continuous weaving traditions in the world. Understanding the knowledge and practice of textile production as a form of cultural heritage is particularly relevant in the Andean context due to erosion of clothing traditions, reuse of traditional textiles on commodities targeted at the tourism market, and loss of knowledge embedded in textile production. We modeled the knowledge of domain experts and represented information about the textile objects in the form of an OWL ontology. We also developed a suite of search facilities, making the digitized fabrics accessible to domain experts and researchers in the area.

The term "positive impact games" evokes many associations. It also implicates a seductive vision of games that are administered like medication to repair or mitigate an individual - or a society's - pain, damage or shortcomings. The talk includes a critical reflection on a number of projects we have worked on in recent years within the "positive impact games lab" at the Institute of Design and Assessment of Technology, TU Wien, as well as an attempt to indentify current scientific questions and perspectives in the field.
Prof. Dr. Peter Purgathofer majored in informatics in Vienna, and has since focused on the issue of design within informatics. In the course of his work he founded and led the UID-Lab, a cooperation with GP designpartners, where they worked on numerous national and international design projects between 1996 and 2004. Among the clients were Ars Electronica center, the CD-Labor für Software Research and the German Sparkassen-Informatikzentrum. UID-Lab has spun off into a design enterprise and is now part of GP designpartners. Prof. Purgathofer is a (co-)winner of an award of distinction at the Prix Ars Electronica 2000 in the category .net, together with Rich Bergerand, Volker Christian (and many others) for the project telezone. Since early 2005 he has been an associate professor for interactive systems, and his habilitation discusses history, theory and practice of design methodology, focused on the design of interactive software.

We present a market design for an open access wireless market. Open access means that in real time, network capacity cannot be withheld—network throughput is priced dynamically by the marginal demand during congestion. In unconstrained times and locations, a nominal fee is paid for network throughput. As in electricity markets, the real-time market provides the foundation for forward markets. Monthly forwards are auctioned before the start of each month; yearly forwards are auctioned before the start of each year. Market participants, both operators and traders, take positions in forward auctions to manage risk and optimize portfolios. Deviations from forward positions are settled at real-time prices based on actual use. The independent system operator runs the network and conducts the real-time, monthly, and yearly auctions of network throughput. An independent market monitor observes the market, identifies problems, and suggests solutions. A board—including affiliated directors representing important stakeholders together with independent directors with subject matter expertise—governs the market. A goal of the market is to provide a secure, robust, wide-coverage platform for mobile communications supporting public safety and universal service. Public safety has pre-emptive rights during emergencies and otherwise has economic use like wholesale operators. A complementary goal is competition. The open access provision brings vibrant competition through low-cost, non-discriminatory entry into the wireless market. The market provides a natural remedy for mergers, allowing operational efficiency gains while increasing competition. Critical funding is provided through efficient congestion pricing that balances supply and demand at every time and location. The market, enabled by flexible handsets and the LTE technology, radically reforms current spectrum policy. The
market coexists and complements the dedicated networks of incumbent carriers, promoting efficient spectrum use and essential innovation.
