  1. Ontology-Based Error Detection in SNOMED-CT.Werner Ceusters, Barry Smith, Anand Kumar & Christoffel Dhaen - 2004 - Proceedings of Medinfo 2004:482-6.
    Quality assurance in large terminologies is a difficult issue. We present two algorithms that can help terminology developers and users to identify potential mistakes. We demon­strate the methodology by outlining the different types of mistakes that are found when the algorithms are applied to SNOMED-CT. On the basis of the results, we argue that both formal logical and linguistic tools should be used in the development and quality-assurance process of large terminologies.

  2. Mistakes in Medical Ontologies: Where Do They Come From and How Can They Be Detected?Werner Ceusters, Barry Smith, Anand Kumar & Christoffel Dhaen - 2004 - Studies in Health and Technology Informatics 102:145-164.
    We present the details of a methodology for quality assurance in large medical terminologies and describe three algorithms that can help terminology developers and users to identify potential mistakes. The methodology is based in part on linguistic criteria and in part on logical and ontological principles governing sound classifications. We conclude by outlining the results of applying the methodology in the form of a taxonomy different types of errors and potential errors detected in SNOMED-CT.

    The Forgotten Tradition: How the Logical Empiricists Missed the Philosophical Significance of the Work of Riemann, Christoffel and Ricci.Marco Giovanelli - 2013 - Erkenntnis 78 (6):1219-1257.
    This paper attempts to show how the logical empiricists’ interpretation of the relation between geometry and reality emerges from a “collision” of mathematical traditions. Considering Riemann’s work as the initiator of a 19th century geometrical tradition, whose main protagonists were Helmholtz and Poincaré, the logical empiricists neglected the fact that Riemann’s revolutionary insight flourished instead in a non-geometrical tradition dominated by the works of Christoffel and Ricci-Curbastro roughly in the same years. I will argue that, in the attempt to (...)

    The Making of the Bear: Further Thoughts on the Printing of the Second Edition of Leviathan.Noel Malcolm - 2007 - Hobbes Studies 20 (1):2-39.
    In a previous study the author proposed that the second edition of Leviathan arose from an abortive attempt to print the text in London in 1670, and consisted partly of sheets salvaged from that attempt, and partly of new sheets printed in Amsterdam later in the 1670s. This article defends and amplifies that account of the printing. It responds to the alternative account presented by the late Karl Schuhmann, noting some problematic features of his theory; it considers the evidence of (...)

    Seeking Feasible Reconciliation: A Transdisciplinary Contextual Approach to Reconciliation.Christoffel H. Thesnaar - 2014 - Hts Theological Studies 70 (2):01-08.
    In South Africa scholars in the broad field of practical theology are currently faced with a daunting challenge: to rethink the reconciling role of the institutional church in the light of continued challenges facing reconciliation within post-apartheid and post-Truth and Reconciliation Commission (TRC) South Africa. This contribution investigates whether the transdisciplinary, region-centred scientific research approach with a focus on the Hölderlin perspective on reconciliation could assist scholars in practical theology to address reconciliation in a post-apartheid and post-TRC society. The article (...)

    An Alternative to the Schwarzschild Solution of GTR.Andrew Thomas Holster - manuscript
    The Schwarzschild solution (Schwarzschild, 1915/16) to Einstein’s General Theory of Relativity (GTR) is accepted in theoretical physics as the unique solution to GTR for a central-mass system. In this paper I propose an alternative solution to GTR, and argue it is both logically consistent and empirically realistic as a theory of gravity. This solution is here called K-gravity. The introduction explains the basic concept. The central sections go through the technical detail, defining the basic solution for the geometric tensor, the (...)

    Farmers' Definitions, Goals, and Bottlenecks of Sustainable Agriculture in the North-Central Region.Christoffel den Biggelaar & Murari Suvedi - 2000 - Agriculture and Human Values 17 (4):347-358.
    Since its inception in 1988, the SAREprogram has sponsored hundreds of projects to exploreand apply economically viable, environmentally sound,and socially acceptable farming systems. Recognizingthat researchers often collaborated with producers andthat producer interest in sustainable agriculture wasincreasing, SARE's North-Central Region began directlyfunding farmers and ranchers in 1992 to test their ownideas on sustainable agriculture. The present articleis based on data from the formative evaluation of thefirst five years (1992 to 1996) of the NCR-SAREProducer Grant Program. The evaluation used acombination of mail (...)

    Farming Systems Development: Synthesizing Indigenous and Scientific Knowledge Systems. [REVIEW]Christoffel den Biggelaar - 1991 - Agriculture and Human Values 8 (1-2):25-36.
    Agricultural development strategies to date were chiefly based on Western technological solutions, with mixed success rates. Farming Systems Research (FSR) was advanced as a way to increase the use of indigenous knowledge of farming to make new technologies more adaptable and appropriate to farming conditions. FSR has enabled researchers to focus attention on people and their knowledge by increasing people's participation in problem identification and new technology validation. In practice, though, FSR continues to be a top-down approach: technologies continue to (...)

    Aberration and the Fundamental Speed of Gravity in the Jovian Deflection Experiment.Sergei M. Kopeikin & Edward B. Fomalont - 2006 - Foundations of Physics 36 (8):1244-1285.
    We describe our explicit Lorentz-invariant solution of the Einstein and null geodesic equations for the deflection experiment of 2002 September 8 when a massive moving body, Jupiter, passed within 3.7’ of a line-of-sight to a distant quasar. We develop a general relativistic framework which shows that our measurement of the retarded position of a moving light-ray deflecting body (Jupiter) by making use of the gravitational time delay of quasar’s radio wave is equivalent to comparison of the relativistic laws of the (...)

    A Strictly Geometric Interpretation of Gravitation in General Relativity.J. P. Kobus - 1973 - Foundations of Physics 3 (1):45-51.
    A geometric interpretation of gravitation is given using general relativity. The law of gravitation is taken in the formR 44=0, whereR 44is the component of the contracted Riemann-Christoffel (Ricci) tensor representing the curvature of time. The remaining curvature components of the contracted Riemann-Christoffel tensor may or may not vanish. All that is required in addition toR 44=0 is that the Gaussian curvatureR be nowhere infinite. The conditionR 44=0 yields a nonlinear wave equation. One of the static degenerate solutions (...)

    The Weight of Extended Bodies in a Gravitational Field with Flat Spacetime.Ø Grøn - 1979 - Foundations of Physics 9 (7-8):501-514.
    Einstein's gravitational field equations in empty space outside a massive plane with infinite extension give a class of solutions describing a field with flat spacetime giving neutral, freely moving particles an acceleration. This points to the necessity of defining the concept “gravitational field” not simply by the nonvanishing of the Riemann curvature tensor, but by the nonvanishing of certain elements of the Christoffel symbols, called the physical elements, or the nonvanishing of the Riemann curvature tensor. The tidal component of (...)

    Gravitation and Universal Fermi Coupling in General Relativity.Hans-Jürgen Treder - 1976 - Foundations of Physics 6 (5):527-538.
    The generally covariant Lagrangian densityG = ℛ + 2K ℒmatter of the Hamiltonian principle in general relativity, formulated by Einstein and Hilbert, can be interpreted as a functional of the potentialsg ikand φ of the gravitational and matter fields. In this general relativistic interpretation, the Riemann-Christoffel form Γ kl i = kl i for the coefficients г kl i of the affine connections is postulated a priori. Alternatively, we can interpret the LagrangianG as a functional of φ, gik, and (...)

    Mystifying Moments in Bible Interpretation: An Exploration of Some Implied Backgrounds to Three Kinds of Unusual Bible Readings.Christoffel Lombaard - 2017 - Hts Theological Studies 73 (3).
    This contribution is part of a series on Methodology and Biblical Spirituality. In this, the fourth contribution, the scope is widened; more practical-analytically oriented, three thoroughly different but nevertheless all unusual kinds of interpretations of the Bible are described, characterised and contextualised. Namely:• In order to explain what are perceived as textual anomalies, some Old Testament authors have been described by US-based medical practitioners as having suffered psychiatric dysfunctions.• The Garden of Eden from Genesis 2 and further has been located (...)

    Collision of Traditions. The Emergence of Logical Empiricism Between the Riemannian and Helmholtzian Traditions.Marco Giovanelli - 2013 - .
    This paper attempts to explain the emergence of the logical empiricist philosophy of space and time as a collision of mathematical traditions. The historical development of the ``Riemannian'' and ``Helmholtzian'' traditions in 19th century mathematics is investigated. Whereas Helmholtz's insistence on rigid bodies in geometry was developed group theoretically by Lie and philosophically by Poincaré, Riemann's Habilitationsvotrag triggered Christoffel's and Lipschitz's work on quadratic differential forms, paving the way to Ricci's absolute differential calculus. The transition from special to general (...)

    Felice Casorati’s Work on Finite Differences and its Influence on Salvatore Pincherle.Riccardo Rosso - 2015 - Archive for History of Exact Sciences 69 (2):153-215.
    This paper, which is mainly based on unpublished material, focuses on the scientific influence that Felice Casorati exerted on Salvatore Pincherle. This influence can be traced, in particular, in Casorati’s work on the finite-difference calculus as conceived and published between 1879 and 1880 when Pincherle was living in Pavia. Casorati’s work has an interesting back story related to his entry to the 1880 Grand Prix of the French Académie des Sciences that helps us in understanding Casorati’s personality. Moreover, the correspondence (...)
