Immigration, asylum and citizenship in Germany: the impact of unification and the Berlin Republic

In recent years, there has been much debate over whether post-unification Germany, often termed the 'Berlin Republic', represents a substantive change from the 'Bonn Republic ', that is, West Germany. This article analyses Germany's immigration and citizenship policy against this background by examining various dimensions of immigration before and after unification. The article argues that both unification itself and Germany's changed international environment have resulted in far-reaching changes in policy, which have forced a reappraisal of Germany's traditional self-image as a 'non-immigration country'.

The debate on human automatism in mid-Victorian England

During the 1830s, Marshall Hall carried out innumerable experiments on a great variety of animals to establish the concept of a ‘reflex arc’. In France F.L.Goltz showed that decerebrate frogs were still capable of complex behaviours. Thomas Laycock in England and Ivan Sechenov in Russia sought to apply the reflex idea to the brain. This paper follows the debate in the periodical literature of mid-Victorian England and discusses the contributions of WB Carpenter, Herbert Spencer, TH Huxley, W Clifford and others. The previous outing of this issue in the post-Cartesian seventeenth century had been largely suppressed by ecclesiastical authority. In the nineteenth century ecclesiastical power had waned, at least in England, and the debate could take a more open form. As neurophysiology and behavioural science developed, with the widespread acceptance of Darwinian evolution, it became more and more difficult to deny that brain and mind were part of the natural world and subject to the usual laws of cause and effect. This, of course, had powerful implications for the human self-image and for jurisprudence. These implications are still with us and the work of neurophysiologists such as Benjamin Libet have only reinforced them. Should humans be regarded as ‘automata’ and, if so, what becomes of ‘free will’, ‘responsibility’, and the rule of law? The Victorian debate is still useful and relevant.

Professions, class and society:solicitors in 19th century Birmingham

The thesis provides an analysis of an occupation in the process of making itself a profession. The solicitors' profession in Birmingham underwent a great many changes during the 19th century against a background of industrialisation and urbanisation. The solicitors' conception of their status and role, in the face of these challenges, had implications for successful strategies of professionalisation. The increased prestige and power of the profession, and especially its elite, are examined in their social context rather than in terms of a technical process, or educational and organisational change. The thesis argues that -the profession's social relationships and broad concerns were significant in establishing solicitors as "professional men". In particular these are related to the profession's efforts to gain control of markets for legal services and increase social status. In the course of achieving these aims a concept of profession and a self-image were articulated by solicitors in order to persuade society and the state of the legitimacy of their claims. The concept of the gentlemanly professional was of critical importance in this instance. The successful creation of a provincial professional "community" by the end of the 19th century rested principally on a social and moral conception of professionalism rather than one which stressed specialised training and knowledge, professional organisations and credentials.

Current practice and opinion in special schools for the maladjusted in England and Wales

This study seeks to describe current practice and opinion in schools for the maladjusted in England and Wales and to exarnlne how far this coincides with earlier descriptions. A review of the literature provides an account of this earlier work, and data accrued from questionnaires completed by 114 schools describe current practice and opinion. The study represents the most extensive empirical enquiry into the work of these schools since 1955 and provides a wide data basis for future research and assessment of progress and change. The data suggest that there is much communality of practice and opinion within the schools, with most schools emphasising their therapeutic rather than their educational purpose. The work is characterised by the wide use and perceived efficacy of warm, caring adult to child relationships, improvement of pupil self-image through success, and individual counselling and discussion, which permeate a structure of routine, discipline and educational concern. Specialised treatments are not used widely and involve only a minority of pupils. Practice tends to be in reference to conduct disordered pupils who are now perceived as the largest single disorder group within the schools, whereas previously neurotic disorders formed the largest single group. The majority of pupils are perceived as underachieving on entry and requiring remedial help: consequently the educational programme has a remedial bias. For staff, qualities of personality are considered to be more valuable than professional skills. The schools differ in the emphasis they allocate to one or more of four identified areas of treatment described as concern for pupils' needs; degree of pupil participation; theoretical orientation: and the use of external controls. There is a diminished reference to psychoanalytical theory and an increased reference to behaviourist theory relative to previous practice. Similarly, the use and perceived importance and effectiveness of pupil participation and unconditional affection has diminished.

Self-contained encrypted image folding

The recently introduced approach for Encrypted Image Folding is generalized to make it self-contained. The goal is achieved by enlarging the folded image so as to embed all the necessary information for the image recovery. The need for extra size is somewhat compensated by considering a transformation with higher folding capacity. Numerical examples show that the size of the resulting cipher image may be significantly smaller than the plain text one. The implementation of the approach is further extended to deal also with color images.

Sparse image representation with encryption

In this thesis we present an overview of sparse approximations of grey level images. The sparse representations are realized by classic, Matching Pursuit (MP) based, greedy selection strategies. One such technique, termed Orthogonal Matching Pursuit (OMP), is shown to be suitable for producing sparse approximations of images, if they are processed in small blocks. When the blocks are enlarged, the proposed Self Projected Matching Pursuit (SPMP) algorithm, successfully renders equivalent results to OMP. A simple coding algorithm is then proposed to store these sparse approximations. This is shown, under certain conditions, to be competitive with JPEG2000 image compression standard. An application termed image folding, which partially secures the approximated images is then proposed. This is extended to produce a self contained folded image, containing all the information required to perform image recovery. Finally a modified OMP selection technique is applied to produce sparse approximations of Red Green Blue (RGB) images. These RGB approximations are then folded with the self contained approach.

Self-organising zooms for decentralised redundancy management in visual sensor networks

When visual sensor networks are composed of cameras which can adjust the zoom factor of their own lens, one must determine the optimal zoom levels for the cameras, for a given task. This gives rise to an important trade-off between the overlap of the different cameras’ fields of view, providing redundancy, and image quality. In an object tracking task, having multiple cameras observe the same area allows for quicker recovery, when a camera fails. In contrast having narrow zooms allow for a higher pixel count on regions of interest, leading to increased tracking confidence. In this paper we propose an approach for the self-organisation of redundancy in a distributed visual sensor network, based on decentralised multi-objective online learning using only local information to approximate the global state. We explore the impact of different zoom levels on these trade-offs, when tasking omnidirectional cameras, having perfect 360-degree view, with keeping track of a varying number of moving objects. We further show how employing decentralised reinforcement learning enables zoom configurations to be achieved dynamically at runtime according to an operator’s preference for maximising either the proportion of objects tracked, confidence associated with tracking, or redundancy in expectation of camera failure. We show that explicitly taking account of the level of overlap, even based only on local knowledge, improves resilience when cameras fail. Our results illustrate the trade-off between maintaining high confidence and object coverage, and maintaining redundancy, in anticipation of future failure. Our approach provides a fully tunable decentralised method for the self-organisation of redundancy in a changing environment, according to an operator’s preferences.

Self-aware and self-expressive camera networks

Smart cameras perform on-board image analysis, adapt their algorithms to changes in their environment, and collaborate with other networked cameras to analyze the dynamic behavior of objects. A proposed computational framework adopts the concepts of self-awareness and self-expression to more efficiently manage the complex tradeoffs among performance, flexibility, resources, and reliability. The Web extra at http://youtu.be/NKe31-OKLz4 is a video demonstrating CamSim, a smart camera simulation tool, enables users to test self-adaptive and self-organizing smart-camera techniques without deploying a smart-camera network.
