AbstractWhile it was traditionally accepted that Hongkongers shared a form of pan-Chinese cultural identification that did not contradict their local distinctiveness, over the last decade Hong Kong has seen the rise of new types of local identity discourses. Most recently, “localists” have been a vocal presence. Hong Kong has – quite unexpectedly – developed a strong claim for self-determination. But how new is “localism” with respect to the more traditional “Hong Kong identity” that appeared in the 1970s? The present study takes a two-dimensional approach to study these discourses, examining not only their framework of identification (local versus pan-Chinese) but also their mode of identification (ethno-cultural versus civic). Using three case studies, the June Fourth vigil, the 2012 anti-National Education protest and the 2014 Umbrella movement, it distinguishes between groups advocating civic identification with the local community (Scholarism, HKFS) and others highlighting ethnic identification (Chin Wan). It argues that while local and national identification were traditionally not incompatible, the civic-based identification with a local democratic community, as advocated by most participants in recent movements, is becoming increasingly incompatible with the ethnic and cultural definition of the Chinese nation that is now being promoted by the Beijing government.

The overview of the current status of quantum cryptography is given in regard to quantum key distribution (QKD) protocols, implemented both on nonentangled and entangled flying qubits. Two commercial R&D platforms of QKD systems are described (the Clavis II platform by idQuantique implemented on nonentangled photons and the EPR S405 Quelle platform by AIT based on entangled photons) and tested for feasibility of their usage in commercial TELECOM fiber metropolitan networks. The comparison of systems efficiency, stability and resistivity against noise and hacker attacks is given with some suggestion toward system improvement, along with assessment of two models of QKD.

Cities and their transportation systems become increasingly complex and multimodal as they grow, and it is natural to wonder whether it is possible to quantitatively characterize our difficulty navigating in them and whether such navigation exceeds our cognitive limits. A transition between different search strategies for navigating in metropolitan maps has been observed for large, complex metropolitan networks. This evidence suggests the existence of a limit associated with cognitive overload and caused by a large amount of information that needs to be processed. In this light, we analyzed the world’s 15 largest metropolitan networks and estimated the information limit for determining a trip in a transportation system to be on the order of 8 bits. Similar to the “Dunbar number,” which represents a limit to the size of an individual’s friendship circle, our cognitive limit suggests that maps should not consist of more than 250 connection points to be easily readable. We also show that including connections with other transportation modes dramatically increases the information needed to navigate in multilayer transportation networks. In large cities such as New York, Paris, and Tokyo, more than 80% of the trips are above the 8-bit limit. Multimodal transportation systems in large cities have thus already exceeded human cognitive limits and, consequently, the traditional view of navigation in cities has to be revised substantially.
