Security Applications for Converging Technologies - Impact on the Constitutional State and the Legal order

In this study we investigate the impact of converging technologies on legal practice and criminology in a forward looking study intended for practitioners and policy makers in the field of legislation, crime prevention, and law enforcement. We look at a 15 years timeframe and discuss the scientific and technical progress in various domains as well as the ethical, legal, and policy dilemmas involved.

Microorganisms in the Deterioration and Preservation of Cultural Heritage

This open access book offers a comprehensive overview of the role and potential of microorganisms in the degradation and preservation of cultural materials (e.g. stone, metals, graphic documents, textiles, paintings, glass, etc.). Microorganisms are a major cause of deterioration in cultural artefacts, both in the case of outdoor monuments and archaeological finds. This book covers the microorganisms involved in biodeterioration and control methods used to reduce their impact on cultural artefacts. Additionally, the reader will learn more about how microorganisms can be used for the preservation and protection of cultural artefacts through bio-based and eco-friendly materials. New avenues for developing methods and materials for the conservation of cultural artefacts are discussed, together with concrete advances in terms of sustainability, effectiveness and toxicity, making the book essential reading for anyone interested in microbiology and the preservation of cultural heritage

Evolution of fuzzy animats in a competitive environment

Collective behaviour is a fascinating field that studies coordinated motion of large groups of similar entities. Probably the most common hypothesis about the origins of collective animal behaviour suggests that it might function as a defensive mechanism against predation. In this thesis we used various computational techniques to study this hypothesis. We started by expanding an existing fuzzy model for the computer simulation of bird flocking with predators and visual perception. We implemented three target selection tactics that take into account the visual perspective of the predator (attack the nearest visible individual, attack the most visually isolated individual, and attack the centre of the visible group). Our results suggest that for prey individuals social behaviour (governed by the separation, alignment and cohesion drives) as opposed to individualistic (governed exclusively by the separation drive) is the most beneficial (predators take longer to capture their target). Predators, on the other hand, capture social prey individuals quicker when they attack the most visually isolated individual, but capture individualistic prey faster if they focus on the nearest prey individual. In the next stage we developed an evolutionary model for tuning hand-crafted composite predator attack/target selection tactics. For reasons of computational simplicity we here expanded on a known mathematical model of prey collective behaviour. This allowed us to concentrate on predator target selection tactics. We investigated the evolution of the optimal tactic with respect to prey behaving collectively and prey that performed a delayed response. With the latter prey individuals instead of responding immediately at the first sight of the predator delay the response to a later point in time and then try to outsmart the predator by performing rapid twists and turns. This might be an advantageous defensive manoeuvre because prey can remain in a compact group for as long as possible and because prey individuals are usually smaller than predators and as such have a higher turn rate. Our results suggest that a composite tactic termed dispersing tactic, where the predator first dives deep into the group of prey and then targets the most peripheral individual, is the best tactic. Experiments with prey's delayed response suggest that prey individuals can indeed increase their survivability by using this defensive manoeuvre and the dispersing tactics seems to be the only tactic capable of at least partially diminishing the effectiveness of the preys' delayed response. This was a clear indication of potential interplay between target selection tactics and prey behaviour. Armed with this knowledge, we developed an artificial life-like open-ended evolutionary model, where the behaviour of prey and predator individuals is governed by fuzzy logic. In this model we focused on the evolution of prey behaviour when prey individuals face different predation tactics. We demonstrated that in this model prey individuals evolve different types of collective behaviour (swarm, milling, polarized, dynamic). Interestingly, the analysis of the evolved rule bases showed a statistically significant difference between different types of behaviour in the proportion of rules that take into account predator related information. This suggested that the predation pressures the prey are subject to during evolution might have an influence on the behaviour that evolves. Our last step of research was thus a controlled experiment where prey evolve under various predation tactics. Here we let prey evolve under four predation tactics, two of which according to previous research pressure prey to evolve dispersing and two pressure prey to evolve grouping. Our results suggest that antagonism in predation pressures, where prey are exposed to predation pressures for which the best response is both grouping and dispersing simultaneously, might be necessary for prey to evolve polarized movement

The role of information technology in supporting the development of science linked technology education

This study builds on my earlier 1983 Masters research at Cranfield, which was an investigation of early technology education in the UK and USA and a pilot evaluation of the introduction of technology education into the curriculum of Stantonbury Campus in Milton Keynes, England. This gave an indication of the international trends in technology education and showed some of the potential of a problem-oriented approach to learning in schools based around a new integration of subjects and skills. It also showed the challenge to existing school teaching staff who often had to learn new skills themselves, often had to teach in new ways, and had to broaden their orientation after being single subject specialists most of their careers. Teaching materials had to be developed from scratch. IT had to be got to grips with. In September 1984, I took the post of Co-ordinator of the Schools Science and Technology Centre at the University of Oxford and had to implement a policy for sciencelinked technology education through a fast-changing period. During 1987 the pace of change accelerated rapidly being driven by the demands of the emerging new National Curriculum. By that time technology education, including IT, seemed to have become accepted as an important theme in the school curriculum in its own right. The Oxford Centre was there to offer in-service support in the development of training and teaching materials. It was, therefore, a good base for a study which could document the challenge of implementing technology education on a wide scale. In the end the sheer pace of change enacted by the government between 1987 and 1992, and shifts of position over the place of technology education, made the study a harder task than I expected. I was aiming at a fast moving target. But I hope the work is of value in exploring the link between the aspirations of those who advocate "technological capability and literacy" in our school population and what is currently being achieved. This thesis tries to explore the key areas of progress we need to make if technology education is to become a reality in our schools
