Is the iPhone and a whole new generation of mobiles and PDAs eclipsing the physical city? Whereas once the metropolis alone brought together people, markets, goods, transport and information, the iPhone and similar handheld devices are changing spatial interaction. From Los Angeles, Benjamin H Bratton ruminates on the full impact of this technological shift. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Through an innovative trade-in-task case study, we explore how Nokia, which is historically one of the most important mobile phone manufacturers in the world, offshored the development and production of three distinct mobile phones at three different points in time. Adjacent to these processes, we find that the value creation in areas such as design and manufacturing knowledge has rapidly shifted away from advanced economies to emerging economies. Moreover, we find that the value added captured by Nokia decreased dramatically over the studied time period. Based on our results, we uss more generally the challenge of multinational corporations to preserve value and how the realisation of the benefits of offshoring must be assessed with respect to the altered requirements for controlling value-adding activities. 相似文献

Valentina Croci profiles the work of entertainment design office Area/Code which foregrounds urban locations in its games. As Croci explains the approach of this NewYork-based partnership, which delivers sat nav-inspired gaming to the mobile phone, demonstrates an inherent understanding of the importance of the physical in enhancing the imaginary.
