In this paper we critically review recent developments in policies, practices and philosophies pertaining to the mediation
between science and the public within the EU and the UK, focusing in particular on the current paradigm of Public Understanding
of Science and Technology (PEST) which seeks to depart from the science information-transmission associated with previous
paradigms, and enact a deliberative democracy model. We first outline the features of the current crisis in democracy and
discuss deliberative democracy as a response to this crisis. We then map out and critically review the broad outlines of recent
policy developments in public-science mediation in the EU and UK contexts, focusing on the shift towards the deliberative-democratic
model. We conclude with some critical thoughts on the complex interrelationships between democracy, equality, science and
informal pedagogies in public-science mediations. We argue that science and democracy operate within distinct value-spheres
that are not necessarily consonant with each other. We also problematize the now common dismissal of information-transmission
of science as inimical to democratic engagement, and argue for a reassessment of the role and importance of informal science
learning for the “lay” public, provided within the framework of a deliberative democracy that is not reducible to consensus
building or the mere expression of opinions rooted in social and cultural givens. This, we argue, can be delivered by a model
of PEST that is creative and experimental, with both educational and democratic functions. 相似文献

The focus of this paper is on the design of a H∞ decentralized observation and control approach for a class of nonlinear disturbed interconnected systems. The proposed scheme is formulated as an optimization problem in terms of linear matrix inequality (LMI) to compute the robust observation and control gain matrices simultaneously, to maximize the bounds on the nonlinearity which the system can tolerate without going unstable, to improve the performance of the proposed control strategy by minimizing the H∞ criterion and to ensure the stability of the closed loop system in the Lyapunov framework despite the exogenous disturbances applied to the subsystems. A simulation is provided on a 3-machine power system, which generators are strongly nonlinear interconnected, to show the efficiency of the designed approach. 相似文献

Museum professionalism remains an unexplored area in museum studies, particularly with regard to what is arguably the core generic question of a sui generis professional knowledge base, and its necessary and sufficient conditions. The need to examine this question becomes all the more important with the increasing expansion of the museum’s roles and functions. This paper starts by mapping out the policy and organizational context within which the roles of museums have expanded in the UK. It then situates the discussion of museum professional knowledge within a cross-disciplinary matrix bearing on the question of what is professional about occupations classified—or classifiable—as professions. Against the backdrop of the current organizational context of the museum as well as theories of professional knowledge, it highlights the ways in which museum work, more specifically museography, poses a distinctive set of questions compared to other ‘professional’ fields; the paper thus homes in on the question of what it is that constitutes the uniqueness of museum professional knowledge in relation to museographic practice and the type of professional knowledge and expertise that can sustain it and enact its creative and educational potentials and affordances. 相似文献

The aim of this article is to trace some lines of thinking towards a conceptualization of the uniqueness of the creative work of museums, the mode of creativeness that belongs exclusively to museums, or at least that museums are capable of by virtue of the types of materials and forms as well as activities unique to what will be referred to as museography. This is linked to the question of what it is that constitutes the uniqueness of museum work as a professional field. The article characterizes the uniqueness of museum professional knowledge primarily in terms of a mode of creativeness, or bricolage in Levi-Strauss’s sense, mediated through the museographic form, and applied to the chance assemblies of materials to generate museum-specific modes of engaging questions—across science, culture, and society—particularly through creating unique temporal arrangements, or durations, that provoke thought, learning, and engagement on museographic terms. Museography’s originality, it is argued, consists in a bricolage that works through the museum’s unique material and form to create learning resources and encounters, museographic assemblages that depart from a conception of linear time as the space of evolutionary narrative to facilitate the experience of Bergsonian durations. 相似文献

This study investigates the problem of robust tracking control for interconnected nonlinear systems affected by uncertainties and external disturbances. The designed H∞ dynamic output-feedback model reference tracking controller is parameterized in terms of linear matrix inequalities (LMIs), which is formulated within a convex optimization problem readily implementable. The resolution of such a problem, guarantying not only the quadratic stability but also a prescribed performance level of the resulting closed-loop system, enables to calculate concurrently the robust decentralized control and observation gain matrices. The established LMI conditions are computed in a single-step resolution to obtain all the controller/observer parameters and therefore to overcome the problem of iterative algorithm based on a multi-stage resolution leading in most cases to conservative and suboptimal solutions. Numerical simulations on diverse applications ranging from a numerical academic example to coupled inverted double pendulums and a 3-strongly interconnected machine power system are provided to corroborate the merit of the proposed control scheme. 相似文献
