Retrieving and recontextualising VET theory

To what extent can we speak of theory specific to vocational education and training (VET) and what is its relevance today? This Special Issue 19 of bwp@ aims to (re)ignite academic discourse on VET theory, retrieving earlier theorisation specific to this field, mainly from Germany, Austria, and Switzerland (the DACH countries) and connecting it both with international perspectives and contemporary debates. We invite papers in English or German that engage with these debates. From an international perspective, the DACH countries are extraordinary both in their proposition of theories of VET sui generis and especially in their influence on the field of policy and practice. By contrast, for example in English-speaking countries, influential theories that address the question of vocational study, whilst drawing extensively on philosophical and social science concepts, developed largely in opposition to policy and practices that positioned vocational learning as an inferior pathway and narrowed its educational scope. The dual apprenticeship model has been widely imitated internationally but without regard to the social partnerships, labour markets and education workforce developed in Germany, and the theories that shaped this system are neither translated nor widely discussed in other languages. While there are several approaches to VET theory, the core of all these approaches is a framework of normative goals of education, a characterisation of how these goals can be reached through vocational education in particular and the formulation of (education) policy implications that are necessary for successful implementation. For example, Kerschensteiner (1901, 1966/1904) in his emphasis on civic virtues as a central aim of education, drew attention to the possibility of attaining such virtues through work, but acknowledged the necessity of a foundation in general education. In contrast, post-war critical approaches, which regularly draw on critical theory (see Habermas 1968; Horkheimer & Adorno 1947), and can be dated to the 1960s and 1970s, identify autonomy and emancipation as central objectives of education (e.g. Lempert 1971; Blankertz 1974, 1979, 1982). The main challenge of VET theory was to explain how these goals also can be reached through vocational education. Blankertz’s answer lay in emphasizing the role of the VET school in widening and deepening knowledge associated with the workspace. The value of these approaches for contemporary VET is dependent on their adaptation to contemporary problems that VET and society are experiencing: migration and integration; climate change and resource consumption, digitisation and globalisation. The tertiarisation of both the economy and of education, as the service sector employs a greater proportion of the population and a growing number of young people enter higher education, even in Germany, also calls into question the relevance of established VET theories. As the structures and forms of organisation that have sustained VET since the 1970s have given way to new social formations and new forms of precarity, the relevance of theories developed during the long period of post-war growth is called into question. Correspondingly, whether a critical standpoint can still be clearly located after the “fall of metaphysics” (Adorno 1998/1965) has also been deemed as questionable (cf. Schäfer 2005). Furthermore, a succession of de-centring approaches including post-structuralist, postmodernist and post-anthropocentric paradigms has suggested the erosion of earlier ‘grand narratives’, the supersession of the ‘enlightenment project’ and even questioned the progressive potential of human labour that explicitly VET theories tend to take for granted. Call for Papers bwp@ Spezial 19 2 Against this background, the bwp@ Special invites contributions that address both VET theory and its application to contemporary issues. The aim is to stimulate a discussion on the continuing significance of VET theory. The aim is to provide space for ideas on how the discipline and its subject could position itself, both nationally and beyond national borders, in its normative-theoretical contours and/or in relation to VET policy and VET practice

Collaborative, academic-industry research approach for advancing systems engineering

In contrast to many technology-based research programmes on which industry and academia may collaborate, a programme in systems engineering – a discipline which is practitioner-focused – requires a different approach to enabling exploitation of research outputs. Those outputs tend to be process, approach and methodological in nature rather than specifically tools and technologies. The NECTISE* research programme is a multi-year, industrially-led research activity focused on developing the systems of systems (SoS) techniques required for Network Enabled Capability. The research consortium includes ten UK universities working in a multi- and cross-disciplinary manner to create more agile approaches to SoS Engineering. This paper will report the integration approaches taken in this research programme and the ways in which exploitation of the research may be achieved and demonstrated. NECTISE is composed of four topic groups investigating Systems Architectures, Through Life Systems Management, Decision Support, and Control and Monitoring, together with a number of cross-cutting themes. It has been driven by industry-derived requirements, and the industry-academic interface is enabled by the transformation of the requirements into a set of research questions. The formulation of such questions will be discussed. A major integrating activity is a set of four demonstrations that take place at regular intervals through the five-year programme. The TTCP** GUIDEx*** was found to be a helpful framework in which to integrate the various component researches for demonstration. The use of scenarios as a means of experimentation and demonstration is long-established; in NECTISE, a scenario approach is taken that embraces not only the military field of operation in which NEC is realised, but also the acquisition and support enterprise that delivers capability components to the military. In this paper, the development of the scenario, its use as a demonstration vehicle, and its role in integration across the research programme will be described, together with an assessment of the extent to which such an approach may aid exploitation of research outputs. Systems approaches have been both the focus of this research programme and the mechanisms through which it is being delivered. We shall assert that a systems approach can be a significant enabler of effective industry-academic collaborative research and we shall identify the important learning that has taken place in NECTISE in this regard. * Network Enabled Capability Through Innovative Systems Engineering ** The Technical Cooperation Program *** Guide for Understanding and Implementing Defense Experimentation (GUIDEx

Through-life NEC scenario development

Scenarios are an important planning tool used by individuals, businesses and governments (especially in the military domain), but many of the currently used approaches focus solely on acute probabilistic timeframes and specific metricated instances of possible future states. Using a mixed method research methodology, we develop a scenario approach in which multiple timeframes are accommodated by fitting vignettes within each other to represent different time levels. This has the advantage of presenting the end-to-end process of capability development and instantiation. We describe the methodology employed to generate such a scenario as a demonstration aid for a large, multidisciplinary research program in systems of systems engineering. The process of scenario generation was an effective integration tool within this program (that included twelve distributed research groups). The resultant scenario enabled engagement of multiple stakeholders in an integrated demonstration of systems related research outputs. We recommend a new class of scenario (a “research scenario”) for incorporation within the standard classifications of scenario types

{\it Ab initio} nuclear structure - the large sparse matrix eigenvalue problem

The structure and reactions of light nuclei represent fundamental and formidable challenges for microscopic theory based on realistic strong interaction potentials. Several {\it ab initio} methods have now emerged that provide nearly exact solutions for some nuclear properties. The {\it ab initio} no core shell model (NCSM) and the no core full configuration (NCFC) method, frame this quantum many-particle problem as a large sparse matrix eigenvalue problem where one evaluates the Hamiltonian matrix in a basis space consisting of many-fermion Slater determinants and then solves for a set of the lowest eigenvalues and their associated eigenvectors. The resulting eigenvectors are employed to evaluate a set of experimental quantities to test the underlying potential. For fundamental problems of interest, the matrix dimension often exceeds $10^{10}$ and the number of nonzero matrix elements may saturate available storage on present-day leadership class facilities. We survey recent results and advances in solving this large sparse matrix eigenvalue problem. W also outline the challenges that lie ahead for achieving further breakthroughs in fundamental nuclear theory using these {\it ab initio} approaches.Comment: SciDAC2009 invited paper; 10 pages and 10 figure

Scenario-based design and evaluation for capability

Scenarios are frequently used within techniques for planning and designing systems. They are an especially helpful means of visualizing and understanding the incorporation of new systems within systems of systems. If used as the basis for decisions about candidate designs, then it is important that such decisions can be rationalized and quantitative assessment is particularly important. In this paper, an approach for developing complex scenarios, which incorporates the phases of systems development and deployment, is presented and a quantitative method of comparison is described. This approach is based on the development of measures of merit and measures of performance. The techniques are illustrated using cases that are relevant to Network Enabled Capability

An evaluation of metal removal during wastewater treatment: The potential to achieve more stringent final effluent standards

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2011 Taylor & Francis.Metals are of particular importance in relation to water quality, and concern regarding the impact of these contaminants on biodiversity is being encapsulated within the latest water-related legislation such as the Water Framework Directive in Europe and criteria revisions to the Clean Water Act in the United States. This review undertakes an evaluation of the potential of 2-stage wastewater treatment consisting of primary sedimentation and biological treatment in the form of activated sludge processes, to meet more stringent discharge consents that are likely to be introduced as a consequence. The legislation, sources of metals, and mechanisms responsible for their removal are discussed, to elucidate possible pathways by which the performance of conventional processes may be optimized or enhanced. Improvements in effluent quality, achievable by reducing concentrations of suspended solids or biochemical oxygen demand, may also reduce metal concentrations although meeting possible requirements for the removal of copper my be challenging
