    Evolution Without Species: The Case of Mosaic Bacteriophages.Gregory J. Morgan & W. Brad Pitts - 2008 - British Journal for the Philosophy of Science 59 (4):745-765.

Given these findings, we argue that each of the most plausible attempts to properly classify bacteriophages into distinct species fail. Mayr's biological species concept fails because there is (...)

  2. Evolution Without Species: The Case of Mosaic Bacteriophages: Articles.Gregory J. Morgan & W. Brad Pitts - 2008 - British Journal for the Philosophy of Science 59 (4):745-765.
    Recent work in viral genomics has shown that bacteriophages exhibit a high degree of mosaicism, which is most likely due to a long history of prolific horizontal gene transfer. Given these findings, we argue that each of the most plausible attempts to properly classify bacteriophages into distinct species fail. Mayr's biological species concept fails because there is no useful viral analog to sexual reproduction. Phenetic species concepts fail because they obscure the mosaicism and the rich reticulated viral histories. Phylogenetic species (...)

    Nonsingularity of Flat Robertson–Walker Models in the Special Relativistic Approach to Einstein's Equations.J. Brian Pitts & W. C. Schieve - 2003 - Foundations of Physics 33 (9):1315-1321.
    Recently the neglected issue of the causal structure in the flat space-time approach to Einstein's theory of gravity has been substantially resolved. Consistency requires that the flat metric's null cone be respected by the null cone of the effective curved metric. While consistency is not automatic, thoughtful use of the naive gauge freedom resolves the problem. After briefly recapitulating how consistent causality is achieved, we consider the flat Robertson–Walker Big Bang model. The Big Bang singularity in the spatially flat Robertson–Walker (...)

    Flat Spacetime Gravitation with a Preferred Foliation.J. B. Pitts & W. C. Schieve - 2001 - Foundations of Physics 31 (7):1083-1104.
    Paralleling the formal derivation of general relativity as a flat spacetime theory, we introduce in addition a preferred temporal foliation. The physical interpretation of the formalism is considered in the context of 5-dimensional “parametrized” and 4-dimensional preferred frame contexts. In the former case, we suggest that our earlier proposal of unconcatenated parametrized physics requires that the dependence on τ be rather slow. In the 4-dimensional case, we consider and tentatively reject several areas of physics that might require a preferred foliation, (...)

    On the Form of Parametrized Gravitation in Flat Spacetime.J. Brian Pitts & W. C. Schieve - 1999 - Foundations of Physics 29 (12):1977-1985.
    In a framework describing manifestly covariant relativistic evolution using a scalar time τ, consistency demands that τ-dependent fields be used. In recent work by the authors, general features of a classical parametrized theory of gravitation, paralleling general relativity where possible, were outlined. The existence of a preferred “time” coordinate τ changes the theory significantly. In particular, the Hamiltonian constraint for τ is removed From the Euler-Lagrange equations. Instead of the 5-dimensional stress-energy tensor, a tensor comprised of 4-momentum density mid flux (...)

    On Parametrized General Relativity.J. Brian Pitts & W. C. Schieve - 1998 - Foundations of Physics 28 (9):1417-1424.
    A physical framework has been proposed which describes manifestly covariant relativistic evolution using a scalar time τ. Studies in electromagnetism, measurement, and the nature of time have demonstrated that in this framework, electromagnetism must be formulated in terms of τ-dependent fields. Such an electromagnetic theory has been developed. Gravitation must also use of τ-dependent fields, but many references do not take the metric's dependence on τ fully into account. Others differ markedly from general relativity in their formulation. In contrast, this (...)

    Null Cones in Lorentz-Covariant General Relativity.J. Brian Pitts & W. C. Schieve - unknown
    The oft-neglected issue of the causal structure in the flat spacetime approach to Einstein's theory of gravity is considered. Consistency requires that the flat metric's null cone be respected, but this does not automatically happen. After reviewing the history of this problem, we introduce a generalized eigenvector formalism to give a kinematic description of the relation between the two null cones, based on the Segre' classification of symmetric rank 2 tensors with respect to a Lorentzian metric. Then we propose a (...)

    Despite its significance in neuroscience and computation, McCulloch and Pitts's celebrated 1943 paper has received little historical and philosophical attention. In 1943 there already existed a lively community of biophysicists doing mathematical work on neural networks. What was novel in McCulloch and Pitts's paper was their use of logic and computation to understand neural, and thus mental, activity. McCulloch and Pitts's contributions included (i) a formalism whose refinement and generalization led to the notion of finite automata (an (...)

    Religion and spirituality are important aspects of the lives of most psychotherapy clients. Unfortunately, many psychotherapists lack the training to effectively and ethically address these issues with their clients. At times, religious or spiritual concerns may be relevant to the reasons clients seek treatment, either as areas of conflict or distress for clients or as sources of strength and support that the psychotherapist may access to enhance the benefit of psychotherapy.
