  • AIRNET : a programme for generating intercity networks
  • Air traffic ; Air transport ; Airport ; Business travel ; Computing ; Leisure ; Network ; Origin-destination ; Route ; Transport ; United States of America
  • 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
  • , origin–destination, business and leisure—that can be used to explore distinct research questions and which can be customised using adjustable parameters that alter how the network is created. Secondly, it can produce each of these networks at multiple
  • time points beginning in 1993, thereby providing researchers access to one of the only sources of longitudinal, dynamic intercity networks.

  • Variability of the morphometric characteristics of valley networks caused by variations in a scale
  • Drainage network ; Fractals ; Geomorphometry ; Spatial scale ; Valley
  • This article indicates the quantitative tools, with assistance of which it is possible to characterize the morphology (shape) of the valley network and determine their variability caused by the scale change. The monitored morphometric
  • characteristics (quantitative tools) have been applied to the paradigmatic examples of the schematic valley networks and have been analyzed in three scales. In order to analyze the valley networks, the most suitable are “valley junction angles” and “homogeneity

  • Centrality ; Cluster ; Connectivity ; Creative industry ; Finland ; Helsinki ; Industry ; Music ; Network ; Spatial concentration
  • municipalities (in terms of population) with a fair number of metal bands. Still, the capital Helsinki is the most prominent cluster of metal music in Finland. A further social network analysis reveals that the metal music cluster of Helsinki has a network

  • Global pharmaceutical and biotechnology firms’ linkages in the world city network
  • Biotechnology ; Connectivity ; Core-periphery ; Head office ; Joint venture ; Multinational firm ; Network ; Pharmaceutical industry ; Producer services ; Production network ; Subsidiary company ; World city
  • This article examines the global pharmaceutical and biotechnology firms’ linkages in the world city network. A micro-scale analysis is presented of how the top ones connected cities across the world in 2010. Subsequently, the nodal centralities
  • of cities included in this sub-sector’s global network are compared with the findings of previous analyses that concentrate on the advanced producer ser-vices sector.

  • Network concepts to describe channel importance and change in multichannel systems : test results for the Jamuna River, Bangladesh
  • The AA. developed a semi-automatic method to derive a chain-like directional network from images that represent the multi-channel river and to connect individual network elements through time. The Jamuna River was taken as an example with a series
  • of Landsat TM and ETM+ images taken at irregular intervals between 1999 and 2004. They quantified the overall importance of individual channels in the entire network using a centrality property. Centrality showed that 3 reaches can be distinguished along
  • the Jamuna with a different network character. Based on the centrality they calculated a weighted braiding index that represents the number of important channels in the network, which is about two in the Jamuna River and which is larger immediately after
  • floods. It is concluded that the network measure centrality provides a novel characterization of river channel networks, highlighting properties and tendencies that have morphological significance.

  • In the paper the role of railway network of Transcarpathia (Zakarpattia) in the international transport connections of Ukraine is investigated. The geopolitical importance and favourable transit location of this region within Ukraine along
  • the international boundaries with Hungary, Romania and Slovakia, is well-known. The paper first focuses on the role of natural, political and transport factors in the development of railway network in the region from a historical perspective. Then the importance
  • of railway network in Transcarpathia for the development of international freight traffic in the USSR is highlighted. The role of geopolitical interests in the past and present is demonstrated. The analytical part of the paper focuses on the latest changes

  • Exploring spatiotemporal and social network factors in community response to a major flood disaster
  • This study examines how the structure of social networks is related to different types of volunteering behavior, including the intensity of volunteering and spatiotemporal aspects of volunteering and focuses on the severe flooding that affected
  • Fargo, North Dakota, in spring 2009. The investigations reveal that volunteers are willing to travel at least five miles and, in some cases, up to approximately eighteen miles to volunteer. The findings suggest that network density and diversity

  • Entrepreneurship within urban and rural areas : creative people and social networks
  • This article examines the role of individual creativity and social networks for both first-timeentrepreneurs and non-entrepreneurs in becoming an entrepreneur and surviving the critical first years in both Danish urban and rural areas. Creativity
  • is found to lead to start-ups in urban areas, where the environment is not only more supportive but also more competitive, but not in rural areas. However, creativity does not increase the chance of success. The particular importance of social networks

  • Temporary streams in a peatland catchment : pattern, timing, and controls on stream network expansion and contraction
  • Climatic change ; Drainage network ; Ecological restoration ; England ; Ephemeral stream ; Hydrology ; Model ; Peat bog ; Runoff ; Underground water ; United Kingdom ; Watershed
  • Electrical resistance (ER) technology has been used to create sensors capable of detecting the presence and absence of flow in ephemeral portions of the channel network, in the Upper North Grain research catchment, a small peatland headwater
  • in the South Pennines, UK. Networks of around 40 sensors were deployed in autumn 2007 and summer 2008. Water table depth was identified as the key factor determining the temporal pattern of streamflow at both the site- and catchment-wide scales. Spatially
  • , network expansion and contraction occurred in a disjointed manner, following a similar pattern between events, suggesting that localized controls are important for flow generation. Spatial controls on flow generation relate to local water table levels

  • The evolution of Taipei’s music industry : cluster and network dynamics in the innovation practices of the music industry
  • Cluster ; Creative industry ; Firm strategy ; Industry ; Innovation ; Music industry ; Network ; Path dependence ; Popular music ; Taipei ; Taiwan
  • 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

  • Drainage network ; Erodibility ; Model ; Mountain ; Numerical model ; Orogeny ; Tectonics ; Watershed
  • The AA. use a landscape evolution model, SIGNUM, to investigate the process of fluvial network organization and the evolution of regular ridge-and-valley patterns on simulated mountain ranges. In particular, they investigate the behavior
  • that is smaller than the original value. A detailed analysis of the simulations, through observations of surface snapshots at repeated time intervals, allows to gain some insight into the mechanisms governing this fluvial network reorganization process.
