Some ethical and legal considerations in the use of Web 2.0

This chapter explores ethical and legal issues that need to be considered by health information professionals when using Web 2.0 technologies. It reviews how the Internet and the Web have affected standards of professional behaviour, and highlights the problems that result when legal frameworks lag behind a rapidly developing technology. It discusses the need for appropriate forms of risk assessment with particular reference to issues of defamation, data protection, and intellectual property rights. A bibliography of further reading is appended

Alive and kicking: a progress report on Open Access, institutional repositories, and health information

An updated version of a talk given at the CILIP HLG Annual Conference, Eastbourne, 11 July 2006.The Open Access movement has promoted two parallel strands of information dissemination - OA publishing, and self-archiving in OA repositories. But while the original focus was peer-reviewed scientific research papers, repositories have extended their role well beyond the original OA concept, generating a lively debate about the role of the OA movement. This paper reviews recent developments internationally, examining different OA strategies, and looking in particular at activities within the field of health information

Regularization by Test Function

Quantum fields are generally taken to be operator-valued distributions, linear functionals of test functions into an algebra of operators; here the effective dynamics of an interacting quantum field is taken to be nonlinearly modified by properties of test functions, in a way that preserves Poincar\'e invariance, microcausality, and the Fock-Hilbert space structure of the free field. The construction can be taken to be a physically comprehensible regularization because we can introduce a sequence that has a limit that is a conventional interacting quantum field, with the usual informal dependence of the effective dynamics on properties of the experimental apparatus made formally explicit as a dependence on the test functions that are used to model the experimental apparatus.Comment: 7 pages.
