Local, National and Global Citizenship

DOI: 10.1080/03004270385200361This paper puts local, national and global citizenship into context post 11.9.01 and pre Johannesburg Earth Summit 2002. It contextulises the strands of the Crick report (1998) and how these integrate with the national curriculum. It argues for a school ethos of citizenship which permeates the whole curriculum rather than a taught citizenship curriculum. The whole notion of citizenship is related to Agenda 21 and Local Agenda 21 and strong bonds are made with Education for Sustainability and Environmental Education.Peer reviewe

Tracking Eudaimonia

A basic challenge to naturalistic moral realism is that, even if moral properties existed, there would be no way to naturalistically represent or track them. Here, the basic structure for a tracking account of moral epistemology is given in empirically respectable terms, based on a eudaimonist conception of morality. The goal is to show how this form of moral realism can be seen as consistent with the details of evolutionary biology as well as being amenable to the most current understanding of representationalist or correspondence theories of truth

In-situ laser retorting of oil shale

Oil shale formations are retorted in situ and gaseous hydrocarbon products are recovered by drilling two or more wells into an oil shale formation underneath the surface of the ground. A high energy laser beam is directed into the well and fractures the region of the shale formation. A compressed gas is forced into the well that supports combustion in the flame front ignited by the laser beam, thereby retorting the oil shale. Gaseous hydrocarbon products which permeate through the fractured region are recovered from one of the wells that were not exposed to the laser system

How secure is ERTMS?

This paper reports on the results of a security analysis of the European Railway Traffic Management System (ERTMS) specifications. ERTMS is designed to be fail-safe and the general philosophy of ‘if in doubt, stop the train’ makes it difficult to engineer a train accident. However, it is possible to exploit the fail-safe behaviour of ERTMS and create a situation that causes a train to halt. Thus, denial of service attacks are possible, and could be launched at a time and place of the attacker’s choosing, perhaps designed to cause maximum disruption or passenger discomfort. Causing an accident is more difficult but not impossible

The curse of Frankenstein: visions of technology and society in the debate over new reproductive technologies

At each successive moment in their development new reproductive technologies have provided the occasion for virulent argument about the role of technology in human affairs. And more generally, technoscientific knowledge has long been held both in awe and suspicion, with the latter acting as a kind of counterbalance to the continuing cultural investment in the image of scientific knowledge as empowerment, as the motive force of beneficial change. Given this cultural ambivalence the paper focuses on media representations of cloning and the 'designer baby' (with the latter enveloping a debate that has run for almost a decade now) and explores the ways utopian images of a world rendered ever more amenable to human desires have been closely shadowed by just as compelling dystopian visions which are nevertheless constructed from the same cultural material. Figures of occidental folklore such as Frankenstein (or Jeckyll or Brave New World), thus function as something of a convenient shorthand for articulating unease with the direction and pace of technological development, or even voicing loss of confidence in the modernist technoscientific project of instrumental control. In these circumstances, the chimeric notions of the 'designer baby' or the human 'clone' appear Janus-faced, concurrently representing the powers of human creativity as well as the monstrous progeny of an excessive epistemophilia. They are in this sense potent metaphors for the biotechnological revolution's declared power to re-shape both nature and society - for 'good' or 'ill'

Magnetism and Magnetic Isomers in Free Chromium Clusters

We have used the Stern-Gerlach deflection technique to study magnetism in chromium clusters of 20-133 atoms. Between 60 K and 100 K, we observe that these clusters have large magnetic moments and respond superparamagnetically to applied magnetic fields. Using superparamagnetic theory, we have determined the moment per atom for each cluster size and find that it often far exceeds the moment per atom present anywhere in the bulk antiferromagnetic lattice. Remarkably, our cluster beam contains two magnetically distinguishable forms of each cluster size with >= 34 atoms. We attribute this observation to structural isomers
