    Scholarly journal access in academic libraries:issues for future development

    As academia progresses towards the 21st century, increases in student numbers, distance learning, changes in copyright licensing and lack of funding means that academic institutions have to look more closely at the use of electronic resources in order to meet these challenges. The "wired campus" and "virtual university" mean more users looking for electronic resources and increased pressure on libraries to provide these services. The development of electronic journals in the early 1990s and the onset of electronic publishing appeared to be a solution to the problem. Journals could be stored electronically thereby saving space, the risk of lose, theft or damage is lessened and costs where significantly reduced. Electronic journals have become an increasingly important part of academic library collections, however they have not proved to be the panacea the profession hoped for. Electronic journal useage has created a new set of issues such as archiving, copyright, cataloguing, site licensing, remote access, hardware requirements and journal design. There are many stakeholders involved in the selection of electronic journals within academic libraries from librarians, to users and publishers. This paper attempts to raise awareness of some of the issues which will have to be considered if scholarly electronic journal publishing is to develop over the next decade. The content and ideas presented in the paper are derived from research undertaken in the area for a student Masters dissertation

    Comment on 'A generalized Helmholtz theorem for time-varying vector fields by A. M. Davis, [Am. J. Phys. 74, 72-76 (2006)]'

    Full text link
    In a recent paper Davis formulated a generalized Helmholtz theorem for a time-varying vector field in terms of the Lorenz gauge retarded potentials. The purposes of this comment are to point out that Davis's generalization of the theorem is a version of the extension of the Helmholtz theorem formulated some years ago by McQuistan and also by Jefimenko and more recently by the present author and to show that Davis's expression for the time-dependent vector field is also valid for potentials in gauges other than the Lorenz gau

    Can Maxwell's equations be obtained from the continuity equation?

    Full text link
    We formulate an existence theorem that states that given localized scalar and vector time-dependent sources satisfying the continuity equation, there exist two retarded fields that satisfy a set of four field equations. If the theorem is applied to the usual electromagnetic charge and current densities, the retarded fields are identified with the electric and magnetic fields and the associated field equations with Maxwell's equations. This application of the theorem suggests that charge conservation can be considered to be the fundamental assumption underlying Maxwell's equations.Comment: 14 pages. See the comment: "O. D. Jefimenko, Causal equations for electric and magnetic fields and Maxwell's equations: comment on a paper by Heras [Am. J. Phys. 76, 101 (2008)].

    Multiple resilience dividends at the community level: a comparative study on disaster risk reduction interventions in different countries

    Get PDF
    The costs of disasters have been increasing in many parts of the world as a result of an increase in exposed and vulnerable assets as well as the effects of climate change. However, investments in disaster risk reduction (DRR)remain insufficient to manage these growing risks. To make investments in DRR more attractive and to shift investments from post-event response and recovery to pre-event resilience, there has been a push to account for the full range of benefits of those investments including economic, ecological and social ‘resilience dividends’. While the concept of ‘multiple resilience dividends’ is now frequently used to strengthen the DRR narrative, it has not yet been widely applied in practice when appraising DRR interventions. The paper analyses the knowledge gaps and challenges that arise from applying the ‘multiple resilience dividends’ in planning, implementation and evaluation of disaster risk reduction interventions on the community level. A newly developed framework is used to analyse empirical survey data on community level DRR interventions as well as five in-depth community case studies in Vietnam, Nepal, Indonesia, Afghanistan and the UK. The analysis reveals a disconnect between the available planning tools and the evidence on materialized multiple resilience dividends, which pose a key obstacle in successfully applying the concept on the community level. The paper concludes that a structured consideration of multiple dividends of resilience from the planning to the monitoring stage is important to secure local buy-in and to ensure that the full range of benefits can materialize

    Closing the gaps. A framework for understanding policies and actions to address losses and damages

    Get PDF
    Global failures to mitigate and adapt to the climate crisis are causing massive losses and costly damages to the lives, livelihoods, and futures of communities around the world. Efforts to address the issue have been highly insufficient, and national and international humanitarian response systems are already overstretched and underfunded. There is a moral imperative to act in solidarity with those who are suffering now, and to develop an approach that will protect generations to come. This policy brief from the Zurich Flood Resilience Alliances explains how we got to this point, and makes urgent recommendations outlining how the international community can to scale up action, and resource a comprehensive approach to averting, minimizing, and addressing losses and damages
