In Communities and Networks, Katherine Giuffre takes the science of social network analysis and applies it to key issues of living in communities, especially in urban areas, exploring questions such as: How do communities shape our lives and identities? How do they foster either conformity or innovation? What holds communities together and what happens when they fragment or fall apart? How is community life changing in response to technological advances?
Refreshingly accessible and built on fascinating case examples, this unique book provides not only the theoretical grounding necessary to understand how and why the burgeoning area of social network analysis can be useful in studying communities, but also clear technical explanations of the tools of network analysis and how to gather and analyze real-world network data. Network analysis allows us to see community life in a new perspective, with sometimes surprising results and insights, and this book enables readers to gain a deeper understanding of social life and the relationships that build (and break) communities.
This engaging text will be an exciting new resource for upper-level undergraduate and beginning graduate students in a wide range of courses including social network analysis, community studies, urban studies, organizational studies, and quantitative methods.
To what extent does community experience differ between low‐context and high‐context societies? Prior literature theorizes that community experience consists of two separate, yet highly related concepts: community attachment, an individual’s general rootedness to a place, and community satisfaction, how well an individual’s community meets their societal needs. We test this conceptualization of community experience across communities in the United States and two Southeast Asian nations: Thailand and Vietnam. We argue that Southeast Asian nations constitute “high‐context” societies with relatively high social integration and solidarity while the United States is more individualized and less socially integrated and thus constitutes a “low‐context” society. Our results provide empirical evidence that individuals’ experience of community varies between low‐ and high‐context societies. These results demonstrate that cultural context continues to matter in regards to the lived experience of community and researchers need to remain vigilant in accounting for such differences as they seek to examine the concept of community more broadly.
What makes mobility complex is that it is full of interactions. Interactions between pedestrians, between cars, between buses, between trains, between vehicles and infrastructure. In any mobility system, each component cannot be studied in isolation, as its future is partly but strongly determined by its interactions with other components and its environment. These interactions make it difficult to separate the components of a complex system. Traditional scientific and engineering methods rely on separability, and thus we need to use novel approaches. If we cannot study components individually, we need to model at the same time two levels of abstraction: the component level and the system level. We must understand how interactions between components give rise to system properties, and also how system properties constrain and promote behaviors and states of the components. Computer simulations have been the ideal tool for this, to the point that they have been compared with microscopes or telescopes which allow us to explore the microworld and the macroworld. Computer simulations allow us to explore the complex world.
Urban transportation is a complex phenomenon. Since many agents are constantly interacting in parallel, it is difficult to predict the future state of a transportation system. Because of this, optimization techniques tend to give obsolete solutions, as the problem changes before it can be optimized. An alternative lies in seeking adaptive solutions. This adaptation can be achieved with self-organization. In a self-organizing transportation system, the elements of the system follow local rules to achieve a global solution. Like this, when the problem changes the system can adapt by itself to the new configuration.
In this chapter, I will review recent, current, and future work on self-organizing transportation systems. Self-organizing traffic lights have proven to improve traffic flow considerably over traditional methods. In public transportation systems, simple rules are being explored to prevent the \equal headway instability” phenomenon. The methods we have used can be also applied to other urban transportation systems and their generality is discussed.
Cities are changing constantly. All urban systems face different conditions from day to day. Even when averaged regularities can be found, urban systems will be more client if they can adapt to changes at the same speeds at which these occur. Technology can assist humans in achieving this adaptation. Inspired by cybernetics, we propose a description of cities as adaptive systems. We identify three main components: information, algorithms, and agents, which we illustrate with current and future examples. The implications of adaptive cities are manifold, with direct impacts on mobility, sustainability, resilience, governance, and society. Still, the potential of adaptive cities will not depend so much on technology as on how we use it.
The Creative City describes a new method of strategic urban planning and examines how people can think, plan and act creatively in the city. It explores how we can make our cities more liveable and vital by harnessing people’s imagination and talent. It does not provide definite answers, but seeks to open out an ‘ideas bank’ of possibilities from which innovations will emerge. Most of us sense that where we live could be a better place. Many of us know of places that show how cities can be made more human and more productive. Yet cities balance on a cusp – decision-makers can repeat past policies in a climate of slow decline, or they can seek to reinvent their city as a vibrant hub of creativity, potential and improving quality of life. Undoubtably, for the most part, old approaches do not work. We cannot solve 21st-century problems with 19th-century mindsets: the dynamics of cities and the world urban system have changed too dramatically.
The documentary ‘Thinking Cities’ deals with one of the most dramatic societal trends happening today: urbanization. The world population is expected to soar to more than 9 billion people by 2050, with roughly 70 percent living in cities. At the same time, Information Communications Technology (ICT) is extending its reach.
These parallel trends are intersecting at a time in which the world faces serious economic, environmental, and social challenges in achieving a more sustainable development. Thinking Cities explores the challenges and opportunities of urbanization in the Networked Society.

Today’s Resilient Community letter is from Marcus Wynne. He’s been on the road, looking at fiercely independent, rural communities across the US, to divine what makes them tick. In this dispatch, he digs into how an informal local economy gets started. It’s important to understand how these economies work. Why?There’s been an explosion in the use of community time banks, local currencies, and barter networks all across the US and EU. In some cases, like depression ravaged Spain and Greece, informal local economies are starting to displace the global financial economy. So, this dispatch is well worth the read. Hope you find it as useful as I did.
