    Does the topology of space fluctuate?Arlen Anderson & Bryce DeWitt - 1986 - Foundations of Physics 16 (2):91-105.
    Evidence is presented that the singularities induced in causal Lorentzian spacetimes by changes in 3-space topology give rise to infinite particle and energy production under reasonable laws of quantum field propagation. In the case of the gravitational field, if 3-space is compact the total energy must vanish. A topological transition therefore induces a violent collapse that effectively aborts the transition, since the collapse mode is the only mode carrying the negative energy needed to compensate the associated infinite energy production. The (...)

    (1 other version)“Science and proven experience” : How should the epistemology of medicine inform the regulation of healthcare?Annika Wallin, Lena Wahlberg, Johannes Persson & Barry Dewitt - forthcoming - Health Policy.
    The Swedish medico-legal concept of “science and proven experience” is both legally important and ambiguous. The conceptual uncertainty associated with it can hamper effective assessment of medical evidence in legal proceedings and encourage medical professionals to distrust legal regulation. We examine normative criteria a functioning medico-legal notion should presumably meet, e.g. clarity, acceptability and consistency with existing laws. We also survey healthcare professionals to see how they understand science and proven experience and thus determine the extent to which their understanding (...)

    A secure procedure for early career scientists to report apparent misconduct. [REVIEW]Alex Davis, Nils-Eric Sahlin, Barry Dewitt & Baruch Fischhoff - 2021 - Life Sciences, Society and Policy 17 (1):1-5.
    Early career scientists sometimes observe senior scientists engage in apparent scientific misconduct, but feel powerless to intervene, lest they imperil their careers. We propose a Secure Reporting Procedure that both protects them, when pursuing those concerns, and treats the senior scientists fairly. The proposed procedure is, we argue, consistent with the ethical principles of the scientific community, as expressed in the codes of its professional organizations. However, its implementation will require changes in procedures and regulations. Those efforts will be a (...)
