She has undertaken a series of studies looking at community care services with a particular interest in services for older people with dementia and their carers and people from minority ethnic groups. Jill Manthorpe is Co-Director of SCWRU with a background in university social work and health professional training at pre- and post-qualifying levels. She has undertaken a range of research studies in areas of community care adult protection professional training and risk. She has published widely with recent books on social policy inquiries abuse and students’ mental health. Her particular interests are in social gerontology and she has undertaken a range of research into older people’s services for voluntary groups local providers and national bodies. Peter Huxley is a qualified social worker with practice experience in child and adult mental health settings. He also has management and Board-level experience in adult mental health and social care services. He is Professor of Social Work Head of the Section of Social Work and Social Care and Deputy Head of Department in the Health Services Research Department at the Institute of Psychiatry at Kings College and Director of SCWRU. He recently completed a national survey of the mental health social work workforce in England

There has been no large-scale study looking at the proportion of social work students in the UK who achieve the professional qualification, although there is some evidence that different groups experience different rates of progression. This article examines progression rates among students studying for the DipSW in England and analyses the factors that influence whether students achieve an award on time (defined as achieving an award without being referred, deferred, failing or withdrawing). The results show that male students, students from a black and minority ethnic group, and students with a self-reported disability have poorer progression rates. However, contrary to the picture in higher education as a whole, older students and students with previously lower levels of educational attainment do not have poorer progression rates. Social work education has important lessons to share with higher-education colleagues in terms of working with an increasingly diverse student group. However, work is needed to identify students at greater risk of non-progression than others and to develop more effective student support strategies.

It has been found that some huge overshoot in the sense of sup-norm may be observed when typical iterative learning control (ILC) algorithms are applied to LTI systems, even though monotone convergence in the sense of λ-norm is guaranteed. In this paper, a new ILC algorithm with adjustment of learning interval is proposed to resolve such an undesirable phenomenon, and it is shown that the output error can be monotonically converged to zero in the sense of sup-norm when the proposed ILC algorithm is applied. A numerical example is given to show the effectiveness of the proposed algorithm.

We consider a system of agents as a layer between services and the network hosts. We present a self-organizing system of agents able to offer services with an increase of the speed, and decrease of the network traffic. A coordination model defines how the agents interact, and how their interactions can be controlled;this includes dynamic creation and destruction of agents, control of communication flows among agents, control of spatial distribution of agents, as well as synchronization of actions over time. Various distances and topological relations are used to explain our self-organizing mechanism. We analyze the stability of the system, and provide a new result regarding a weak form of stability depending only on the moment of the first requests of agents by hosts. Finally we provide a visualization of the services evolution using self-organizing maps, and presenting a service clustering structure.

Software Verification: Infinite-State Model Checking and Static Program Analysis 2006

作者： Bouajjani, Ahmed Esparza, Javier Schwoon, Stefan Strejček, Jan LIAFA University of Paris 7 France Institute for Formal Methods in Computer Science University of Stuttgart Germany

We introduce asynchronous dynamic pushdown networks (ADPN), a new model for multithreaded programs in which pushdown systems communicate via shared memory. ADPN generalizes both CPS (concurrent pushdown systems) [QR05] and DPN (dynamic pushdown networks) [BMOT05]. We show that ADPN exhibit several advantages as a program model. Since the reachability problem for ADPN is undecidable even in the case without dynamic creation of processes, we address the bounded reachability problem [QR05], which considers only those computation sequences where the (index of the) thread accessing the shared memory is changed at most a fixed given number of times. We provide efficient algorithms for both forward and backward reachability analysis. The algorithms are based on automata techniques for symbolic representation of sets of configurations. © 2006 Dagstuhl Seminar Proceedings. All rights reserved.

30th Annual NASA/IEEE Software Engineering Workshop

Complex software systems typically involve-features like time, concurrency and probability, where probabilistic computations play an increasing role. It is challenging to formalize languages comprising all these features. In this paper we integrate probability, time and concurrency in one single model, where the concurrency-feature is modelled using shared-variable based communication. The probability feature is represented by a probabilistic nondeterministic choice, probabilistic guarded choice and a probabilistic version of parallel composition. We formalize an operational semantics for such an integration. Based on this model we define a bisimulation relation, from which an observational equivalence between probabilistic programs is investigated and a collection of algebraic laws are explored. We also implement a prototype of the operational semantics to animate the execution of probabilistic programs.

Current Wiki engines are mostly monolithic applications which intermingle parser, user interface and data management backend. In this paper we show how these three components can be realised as lightweight, REST-style web services. We explain why this separation is useful and how the wiki community benefits from such an approach. Additionally, the presented wiki allows semantic statements and queries over the model.

In the automotive field, software development methods and tools are used to cope with the high complexity of automotive software development. However, problems occur with the tracing of information, the assessment and monitoring of the development status, late and thus expensive changes, etc, which lead to increasing development costs and time as well as quality deficits. Our experience with recent projects have shown that the key to solving these problems lies in providing proper answers to the following questions: (1) How can development methods be assembled? (2) How can the use of a variety of development methods be supported by an appropriate tool? To answer these questions, we introduce a tool integration approach that is strongly based on the integration of development methods. The contribution of this paper is (a) a method integration approach that considers fine-grained method objects and their specific structure in addition to the usually considered artifacts, (b) an approach to tool integration that overcomes the deficits of heterogeneous tool environments and utilizes the results of the methodical understanding.

The electromagnetic (EM) measurements obtained by using one transmitter and one receiver antenna in a borehole environment are simulated. The measurements are used to assess electrical properties of rock formations. First, logging instruments as well as rock formation properties are assumed to exhibit axial symmetry around the axis of a vertical borehole. The optimal mesh for axially symmetric problem is obtained by a 2D self-adaptive goal-oriented hp-Finite Element Method (FEM) that delivers exponential convergence rates in terms of the quantity of interest against the CPU time. The 3D mesh is obtained by full revolution of the generated 2D mesh. The computations are then performed for angles of formation layers deviated by 30, 45 and 60 degrees. The concurrent engineering infrastructure that solves the problem automatically in parallel is presented. The 3D code has been verified by comparison of numerical results with the known exact solution of the problem of antenna radiating into a homogenous space, and by comparison of results of 2D and 3D code for the problem with axially symmetric layers in formation. © 2006 The authors.
