  • AIRNET : a programme for generating intercity networks
  • This paper introduces and demonstrates a new programme, AIRNET, which processes airline traffic data from the US Bureau of Transportation Statistics to produce networks among US cities and airports. First, AIRNET produces four types of network—route
  • time points beginning in 1993, thereby providing researchers access to one of the only sources of longitudinal, dynamic intercity networks.

  • of the emergent landscapes of smart growth. In the new morphology of smart growth landscapes, density, (de)segregation, class, race, land recycling, regional-scale compactness, and other key dynamics appear to be combining in complex and at times surprising ways.

  • ). Information derived from satellite data supports the characterization of geomorphologically dynamic coasts at regional scales. With a rich and open access archive of imagery, a commitment to continuity, and compatibility with the Earth observation missions
  • of other space programs, the Landsat mission offers useful and otherwise unavailable data for monitoring of coastal areas.

  • Protracted active surge phase in the high arctic (Svalbard) : dynamic development and morphological impact
  • Arctic Region ; Cold area ; Geomorphology ; Glacial surge ; Glacier ; Glacier dynamics ; Impact ; Model ; Moraine ; Svalbard
  • Glacial surges in Svalbard are protracted and characterized by individual dynamic evolution, in contrast to many other areas, which calls for a subdivision of the classic two-phased surge cycle. A dominating part of the ice masses seem to have

  • This paper explores the existence of different types of static and dynamic externalities and shows the relationship between externalities, interregional trade, and cluster policy. First, it contributes to a better characterization of dynamic
  • externalities by extending the “advantages of backwardness” approach, formerly developed to explain the catching-up of national economies, to the regional conecontext. Second, it presents a new model that relates static and dynamic externalities
  • regions. The major conclusion is that policy must pursue a combination of the comparative advantage principle with one type of dynamic externalities un-covered in this paper: the “related variety benefits” of agglomeration.

  • Value chain dynamics, settlement trajectories and regional development
  • This article examines value chain dynamics, settlement trajectories and regional development. Through the examples of storable perennial crops (cocoa in Ghana and coffee in Vietnam), it argues that livelihood diversification – or lack thereof
  • – indicates particular settlement trajectories that constitute regional development pathways. It is also suggested that the understanding of how regions are shaped by value chain dynamics will improve by adding elements from global production network theory

  • Can δ13C abundance, water-soluble carbon, and light fraction carbon be potential indicators of soil organic carbon dynamics in Zoigê wetland?
  • In this study, four wetland sites and one degraded wetland site in the Zoigê alpine wetland, located at the Qinghai-Tibet Plateau, were selected to investigate the relationships of stable isotope and labile organic carbon dynamics with groundwater
  • elevation or water table level. The AA.also examine if the δ13C abundance, soil water soluble organic carbon (WSOC), light fraction organic carbon (LFOC), can be used as potential indicators of soil organic carbon (SOC) dynamics in these wetland sites
  • . The results showed that the plant dominant species in the degraded wetland site were different from those in the non-degraded wetland sites. The regression analysis showed that LFOC was the best potential indicator of SOC dynamics with WSOC and soil δ13C being

  • The evolution of Taipei’s music industry : cluster and network dynamics in the innovation practices of the music industry
  • This paper explores the spatial and organisational dynamics of innovation activities using Taipei’s music industry as a case study. It illustrates how the cluster and network elements of the music industry are intertwined in innovation practices
  • . It argues that the innovation dynamics of Taipei’s music industry are a hybrid feature of Taipei’s cluster environment and the strategic competencies of music project networks rather than the local cluster effect. In conclusion, a different trajectory
  • for the evolution of Taipei’s music industry is presented. Additionally, this dynamic process between cluster and network makes Taipei a hybrid creative platform that is an active element in the cultivation of the innovative competencies of Taipei’s music producers

  • Michel Foucault and the smart city: power dynamics inherent in contemporary governing through code
  • Drawing upon Michel Foucault’s approach to power and governmentality, this paper explores the internal logics and dynamics of software-mediated techniques used to regulate and manage urban systems. Empirically, it investigates two high-profile pilot
