Mainstream security analyses and security models are discussed. The central argument is that the multi-dimensional conditions, which are considered by analysts as central to the security of all collectives, are not representative of all cultures. Therefore, mainstream models are not suitable for every security collective's cultural security requirements.

Looking mainly at the changing nature of the U.S.-Japan security alliance since 11 September 2001, this thesis argues that the recent emergence of a more assertive Japanese security policy has led to a more robust Chinese response to perceived security challenges from Tokyo and Washington.

Australia has developed sophisticated national security policies and physical security agencies to protect against current and future security threats associated with critical infrastructure protection and cyber warfare protection. This paper will discuss some of the common security risks that face Australia and how their government policies and strategies have been developed and changed over time, for example, the proposed Australian Homeland Security department. This paper will discuss the different steps that Australia has undertaken in relation to developing national policies to deal with critical infrastructure protection.

 This article draws on fourth generation strategic culture debates to show the gap between the rhetoric of Australian defence and the more modest reality. Our analysis shows that these limits derive from tensions between national strategic culture and organizational strategic subcultures. There are serious debates in the nation regarding the preferred course of the Australian military and security policy. This article frames these debates by examining the ‘keepers’ of Australia's national strategic culture, the existence of several competing strategic subcultures, and the importance of norm entrepreneurs in changing defence and national security thinking. Strategic subcultures foster compartmentalization, constraints, and bureaucratic silos that narrow national conceptions of security threats and opportunities, and impinge on the formation of coherent foreign and defence policy in relation to the Asia-Pacific region. This analysis shows that a distinct national strategic culture and organizational strategic subcultures endure beyond individual governments, placing potential limits on Australia's interface with other Asia-Pacific strategic cultures in the future.

Development of PCB-integrateable microsensors for monitoring chemical species is a goal in areas such as lab-on-a-chip analytical devices, diagnostics medicine and electronics for hand-held instruments where the device size is a major issue. Cellular phones have pervaded the world inhabitants and their usefulness has dramatically increased with the introduction of smartphones due to a combination of amazing processing power in a confined space, geolocalization and manifold telecommunication features. Therefore, a number of physical and chemical sensors that add value to the terminal for health monitoring, personal safety (at home, at work) and, eventually, national security have started to be developed, capitalizing also on the huge number of circulating cell phones. The chemical sensor-enabled “super” smartphone provides a unique (bio)sensing platform for monitoring airborne or waterborne hazardous chemicals or microorganisms for both single user and crowdsourcing security applications. Some of the latest ones are illustrated by a few examples. Moreover, we have recently achieved for the first time (covalent) functionalization of p- and n-GaN semiconductor surfaces with tuneable luminescent indicator dyes of the Ru-polypyridyl family, as a key step in the development of innovative microsensors for smartphone applications. Chemical “sensoring” of GaN-based blue LED chips with those indicators has also been achieved by plasma treatment of their surface, and the micrometer-sized devices have been tested to monitor O2 in the gas phase to show their full functionality. Novel strategies to enhance the sensor sensitivity such as changing the length and nature of the siloxane buffer layer are discussed in this paper.

The United Sates was founded on the principles of freedom. Events in recent history have threatened the freedoms we as individuals enjoy. Notably, changes to government legislation and policies regarding access to environmentally sensitive information following September 11, 2001, are troubling. The government has struggled with a difficult balancing act. The public has the right of access to information, yet, information some view as sensitive or dangerous must be kept out of the hands of terrorists. This project examines and discusses the information access debate within the United States and how to best provide the public environmentally sensitive information.

In the wake of the disclosures surrounding PRISM and other US surveillance programmes, this paper assesses the large-scale surveillance practices by a selection of EU member states: the UK, Sweden, France, Germany and the Netherlands. Given the large-scale nature of these practices, which represent a reconfiguration of traditional intelligence gathering, the paper contends that an analysis of European surveillance programmes cannot be reduced to a question of the balance between data protection versus national security, but has to be framed in terms of collective freedoms and democracy. It finds that four of the five EU member states selected for in-depth examination are engaging in some form of large-scale interception and surveillance of communication data, and identifies parallels and discrepancies between these programmes and the NSA-run operations. The paper argues that these programmes do not stand outside the realm of EU intervention but can be analysed from an EU law perspective via i) an understanding of national security in a democratic rule of law framework where fundamental human rights and judicial oversight constitute key norms; ii) the risks posed to the internal security of the Union as a whole as well as the privacy of EU citizens as data owners and iii) the potential spillover into the activities and responsibilities of EU agencies. The paper then presents a set of policy recommendations to the European Parliament.
