Universal resilience patterns in complex networks

"Resilience, a system's ability to adjust its activity to retain its basic functionality when errors, failures and environmental changes occur, is a defining property of many complex systems. Despite widespread consequences for human health, the economy and the environment, events leading to loss of resilience—from cascading failures in technological systems to mass extinctions in ecological networks—are rarely predictable and are often irreversible. These limitations are rooted in a theoretical gap: the current analytical framework of resilience is designed to treat low-dimensional models with a few interacting components, and is unsuitable for multi-dimensional systems consisting of a large number of components that interact through a complex network. Here we bridge this theoretical gap by developing a set of analytical tools with which to identify the natural control and state parameters of a multi-dimensional complex system, helping us derive effective one-dimensional dynamics that accurately predict the system's resilience. The proposed analytical framework allows us systematically to separate the roles of the system's dynamics and topology, collapsing the behaviour of different networks onto a single universal resilience function. The analytical results unveil the network characteristics that can enhance or diminish resilience, offering ways to prevent the collapse of ecological, biological or economic systems, and guiding the design of technological systems resilient to both internal failures and environmental changes."

Design for Action: designing the immaterial artefact

"Throughout most of history, design was a process applied to physical objects. Raymond Loewy designed trains. Frank Lloyd Wright designed houses. Charles Eames designed furniture. Coco Chanel designed haute couture. Paul Rand designed logos. David Kelley designed products, including (most famously) the mouse for the Apple computer.

But as it became clear that smart, effective design was behind the success of many commercial goods, companies began employing it in more and more contexts. High-tech firms that hired designers to work on hardware (to, say, come up with the shape and layout of a smartphone) began asking them to create the look and feel of user-interface software. Then designers were asked to help improve user experiences. Soon firms were treating corporate strategy making as an exercise in design. Today design is even applied to helping multiple stakeholders and organizations work better as a system.

This is the classic path of intellectual progress. Each design process is more complicated and sophisticated than the one before it. Each was enabled by learning from the preceding stage. Designers could easily turn their minds to graphical user interfaces for software because they had experience designing the hardware on which the applications would run. Having crafted better experiences for computer users, designers could readily take on nondigital experiences, like patients' hospital visits. And once they learned how to redesign the user experience in a single organization, they were more prepared to tackle the holistic experience in a system of organizations."

Density Design: a Politecnico di Milano research lab

"DensityDesign is a Research Lab in the design department (INDACO) of the Politecnico di Milano. It focuses on the visual representation of complex social, organizational and urban phenomena. Although producing, collecting, and sharing information has become much easier, robust methods and effective visual tools are still needed to observe and explore the nature of complex issues.

Our research aim is to exploit the potential of information visualization and information design and provide innovative and engaging visual artifacts to enable researchers and scholars to build solid arguments. By rearranging numeric data, reinterpreting qualitative information, locating information geographically, and building visual taxonomies, we can develop a diagrammatic visualization – a sort of graphic shortcut – to describe and unveil the hidden connections of complex systems. Our visualizations are open, inclusive, and preserve multiple interpretations of complex phenomena.

DensityDesign is committed to collaborating with other researchers and organizations devoted to academic independence and rigor, open enquiry, and risk taking to enhance our understanding of the world."

reMap: visualcomplexity projects visualised interactively

"reMap is a Bestiario project based on visualcomplexity.com. Visual Complexity.com is the most complete and well organized collection of visualization projects related with complex systems. Manuel Lima's compilation is priceless for all of us working on the visualization fields. But also artists, scientists, humanists, educators… can find here inspiration and knowledge. VC is not only a compilation: each project is displayed with rich contextual information, including a text and visitors comments, and the whole project is enriched with stats, a book selection, external links, trend analysis on contents and depiction techniques, and a blog.

reMap displays visualcomplexity.com projects allowing navigation using a semantic approach and depicting relations among them. Images and texts belong to vc portal. Tags are assigned using a semantic engine created by Bestiario."
