The multi-scalar nature of urban security and public safety: Crime prevention from local policy to policing in Lisbon (Portugal) and Memphis (the United States)

The article contributes to recent discussions on convergence/divergence of local policies for urban security and public safety amid globalization, exploring comparatively local approaches to crime prevention and explaining differences/similarities through multilevel connections. I analyze situational prevention, social policy and proximity/community policing in two “not-so-global” metropolises: Lisbon, where security is the goal of a wide set of policies in many fields; and Memphis, where social problems have become security issues and policing the only game in town. Differing approaches are explained on the grounds of political traditions, neoliberalization of policy and multilevel relations among polities. I discuss implications for the relation between policy and policing: police attempts at social outreach amid coupling/decoupling of security with/from urban policy; and the “mission creep” of policing when it is expected to lead prevention. Conclusions advocate that policy reform is necessary at many levels to deal with the intersection of crime, retrenching welfare and aggressive policing in US cities such as Memphis.This research was supported by the Fundação para a Ciència e Tecnologia (Grants SFRH/BPD/86394/2012 and UID/SOC/50013/2013), a Fulbright Visiting Scholar grant (U.S.–Italy Commission) sponsored by the U.S. Department of State and the Italian Ministry of Foreign Affairs, and The Benjamin L.

History-sensitive versus future-sensitive approaches to security in distributed systems

We consider the use of aspect-oriented techniques as a flexible way to deal with security policies in distributed systems. Recent work suggests to use aspects for analysing the future behaviour of programs and to make access control decisions based on this; this gives the flavour of dealing with information flow rather than mere access control. We show in this paper that it is beneficial to augment this approach with history-based components as is the traditional approach in reference monitor-based approaches to mandatory access control. Our developments are performed in an aspect-oriented coordination language aiming to describe the Bell-LaPadula policy as elegantly as possible. Furthermore, the resulting language has the capability of combining both history- and future-sensitive policies, providing even more flexibility and power.Comment: In Proceedings ICE 2010, arXiv:1010.530

Rising Powers and State Transformation: The Case of China

This article draws attention to the transformation of statehood under globalisation as a crucial dynamic shaping the emergence and conduct of ‘rising powers’. That states are becoming increasingly fragmented, decentralised and internationalised is noted by some international political economy and global governance scholars, but is neglected in International Relations treatments of rising powers. This article critiques this neglect, demonstrating the importance of state transformation in understanding emerging powers’ foreign and security policies, and their attempts to manage their increasingly transnational interests by promoting state transformation elsewhere, particularly in their near-abroad. It demonstrates the argument using the case of China, typically understood as a classical ‘Westphalian’ state. In reality, the Chinese state’s substantial disaggregation profoundly shapes its external conduct in overseas development assistance and conflict zones like the South China Sea, and in its promotion of extraterritorial governance arrangements in spaces like the Greater Mekong Subregion

The future of sovereignty in multilevel governance Europe: a constructivist reading

Multilevel governance presents a depiction of contemporary structures in EU Europe as consisting of overlapping authorities and competing competencies. By focusing on emerging non-anarchical structures in the international system, hence moving beyond the conventional hierarchy/anarchy dichotomy to distinguish domestic and international arenas, this seems a radical transformation of the familiar Westphalian system and to undermine state sovereignty. Paradoxically, however, the principle of sovereignty proves to be resilient despite its alleged empirical decline. This article argues that social constructivism can explain the paradox, by considering sovereign statehood as a process-dependent institutional fact, and by showing that multilevel governance can feed into this process

A conditional role-involved purpose-based access control model

This paper presents a role-involved conditional purpose-based access control (RCPBAC) model, where a purpose is defined as the intension of data accesses or usages. RCPBAC allows users using some data for certain purpose with conditions. The structure of RCPBAC model is defined and investigated. An algorithm is developed to achieve the compliance computation between access purposes (related to data access) and intended purposes (related to data objects) and is illustrated with role-based access control (RBAC) to support RCPBAC. According to this model, more information from data providers can be extracted while at the same time assuring privacy that maximizes the usability of consumers' data. It extends traditional access control models to a further coverage of privacy preserving in data mining environment as RBAC is one of the most popular approach towards access control to achieve database security and available in database management systems. The structure helps enterprises to circulate clear privacy promise, to collect and manage user preferences and consent
