    Systematic innovation in a world of uncertainty
    (2017) Laszlo, Alexander
    "Systemic Innovation is a field of praxis that is rapidly taking shape as a key driver in R&D initiatives focused on integral sustainability the world over. This field curates the exploration of socio-technical systems design, implementation and insertion in society in ways that foster planetary thrivability at local and global (aka ‘glocal’) levels. To do so, it adopts a transformative approach to characteristically “wicked” societal problems through the transdisciplinary study of ways in which pragmatic socio-technical systems innovation can dissolve VUCA challenges (i.e., those that are characteristically volatile, uncertain, complex and ambiguous). This paper explores how insights from the systems sciences can directly influence real-world socio-technical systems change. By considering both the systemic leverage points and systemic nurturance spaces that foster the emergence of innovations for thrivability, the field of systemic innovation is developing new methods, models and means of emerging ecosystems of R&D+i (research and development plus innovation). Results include the generation of socio-technical solutions that are synergetic with each other (thereby forming collective incubators or innovation greenhouses based on the application of collective intelligence). The emergence of such innovation ecosystems requires leadership and systemic innovation that incorporates social values, technological creativity, economic opportunity and environmental integrity. This paper considers themes of innovation, leadership, connective intelligence, collective intelligence, collective creativity, design thinking, systems practice, entrepreneurial experimentation and other considerations related to the emerging field of leadership and systemic innovation."

    User-centered road network traffic analysis with MobilityDB
    (2022) Sakr, Mahmoud; Zimányi, Esteban; Vaisman, Alejandro Ariel; Bakli, Mohamed
    "Performance indicators of road networks are a long-lasting topic of research. Existing schemes assess network properties such as the average speed on road segments and the queuing time at intersections. The increasing availability of user trajectories, collected mainly using mobile phones with a variety of applications, creates opportunities for developing user-centered performance indicators. Performing such an analysis on big trajectory data sets remains a challenge for the existing data management systems, because they lack support for spatiotemporal trajectory data. This article presents an end-to-end solution, based on MobilityDB, a novel moving object database system that extends PostgreSQL with spatiotemporal data types and functions. A new class of indicators is proposed, focused on the users' experience. The indicators address the network design, the traffic flow, and the driving comfort of the motorists. Furthermore, these indicators are expressed as analytical MobilityDB queries over a big set of real vehicle trajectories."

    Why nestedness in mutualistic networks?
    (2007) Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J.; Devoto, Mariano; Medan, Diego; Zimmermann, Martín; Delbue, Ana María
    "We investigate the relationship between the nested organization of mutualistic systems and their robustness against the extinction of species. We establish that a nested pattern of contacts is the best possible one as far as robustness is concerned, but only when the least linked species have the greater probability of becoming extinct. We introduce a coefficient that provides a quantitative measure of the robustness of a mutualistic system."
