    In 1952, Heinrich Scholz published a question in The Journal of Symbolic Logic asking for a characterization of spectra, i.e., sets of natural numbers that are the cardinalities of finite models of first order sentences. Günter Asser in turn asked whether the complement of a spectrum is always a spectrum. These innocent questions turned out to be seminal for the development of finite model theory and descriptive complexity. In this paper we survey developments over the last 50-odd years (...)

    Autism spectrum disorders (ASDs) are an issue of growing public health significance. This set of neurodevelopmental disorders, which includes autistic disorder, Asperger syndrome, and pervasive developmental disorder not otherwise specified (PDD-NOS), is characterized by abnormalities in one or more of the following domains: language use, reciprocal social interactions, and/or a pattern of restricted interests or stereotyped behaviors. Prevalence estimates for ASDs have been increasing over the past few decades, with estimates at ~5/10,000 in the 1960s, and current estimates as (...)

    Functionalism, a philosophical theory, has empirical consequences. Functionalism predicts that where systematic transformations of sensory input occur and are followed by behavioral accommodation in which normal function of the organism is restored such that the causes and effects of the subject's psychological states return to those of the period prior to the transformation, there will be a return of qualia or subjective experiences to those present prior to the transform. A transformation of this type that has long been of philosophical (...)

    We numerically solve the functional differential equations (FDEs) of 2-particle electrodynamics, using the full electrodynamic force obtained from the retarded Lienard–Wiechert potentials and the Lorentz force law. In contrast, the usual formulation uses only the Coulomb force (scalar potential), reducing the electrodynamic 2-body problem to a system of ordinary differential equations (ODEs). The ODE formulation is mathematically suspect since FDEs and ODEs are known to be incompatible; however, the Coulomb approximation to the full electrodynamic force has been believed to (...)

    I compare a ‘realist’ with a ‘social–relational’ perspective on our judgments of the moral status of artificial agents (AAs). I develop a realist position according to which the moral status of a being—particularly in relation to moral patiency attribution—is closely bound up with that being’s ability to experience states of conscious satisfaction or suffering (CSS). For a realist, both moral status and experiential capacity are objective properties of agents. A social relationist denies the existence of any such objective properties in (...)

    We present a solution to the ghost problem in fourth order derivative theories. In particular we study the Pais–Uhlenbeck fourth order oscillator model, a model which serves as a prototype for theories which are based on second plus fourth order derivative actions. Via a Dirac constraint method quantization we construct the appropriate quantum-mechanical Hamiltonian and Hilbert space for the system. We find that while the second-quantized Fock space of the general Pais–Uhlenbeck model does indeed contain the negative norm energy (...)

    Our account of the problem of the classical limit of quantum mechanics involves two elements. The first one is self-induced decoherence, conceived as a process that depends on the own dynamics of a closed quantum system governed by a Hamiltonian with continuous spectrum; the study of decoherence is addressed by means of a formalism used to give meaning to the van Hove states with diagonal singularities. The second element is macroscopicity represented by the limit $\hbar \rightarrow 0$ : (...)

    We investigate theories of initial segments of the standard models for arithmetics. It is easy to see that if the ordering relation is definable in the standard model then the decidability results can be transferred from the infinite model into the finite models. On the contrary we show that the Σ₂—theory of multiplication is undecidable in finite models. We show that this result is optimal by proving that the Σ₁—theory of multiplication and order is decidable in finite models as well (...)

    In this paper I discuss John Bickle�s attempt to provide a formal procedure to locate a certain reduction relation in the Hooker�s and Churchland�s New wave reductionist spectrum.

I suggest a way to put the generality problem to work by making full and explicit use of a sliding scale--a "narrow-broad spectrum of trait ascription"-- and by accounting (...)

Unfortunately, it is in conflict with some quite robust intuitions about the possibility of phenomenal spectrum inversion without misrepresentation.

A method of introducing fluctuations in a conformally flat Riemannian space-time metric due to ultrahigh energy particles is presented, from which a nonlinear dynamics of particles and equations for the electromagnetic field are obtained. The former admits the acceleration mechanism for cosmic-ray particles and the extreme energy increases during the evolution of the Universe. (...)

Both individual and environmental approaches necessarily include significant influences from social networks, but how and under what conditions social networks influence behavior change is often not clearly mapped out either in the obesity literature or in many intervention designs. In this paper, we provide an analysis of recent empirical work in obesity research that explicates (...)

    The classical two-body system with Lorentz-invariant Coulomb work function V = -k/ρ is solved in 3+1 dimensions using the manifestly covariant Hamiltonian mechanics of Stückelberg. Particular solutions for the reduced motion are obtained which correspond to bound attractive, unbound attractive, and repulsive scattering motion. A lack of perihelion precession is found in the bound attractive orbit, and the semiclassical hydrogen spectrum subsequently contains no fine structure corrections. It is argued that this prediction is indicative of the correct classical special (...)

  47. James Franklin, Australian Philosophy. Sydney Philosophy Forum.score: 24.0
    Greek, Latin and Ancient History. Instead, after a good result in mathematics, I decided to pursue that instead. That left me with an extra subject to choose to fill up first year. What was this "Philosophy" on offer? I couldn't understand where there was something in the spectrum of knowledge for philosophy to be about. Biology was about cats, English was about language and literature, mathematics was about numbers (I was not yet philosophically smart enough to realise there was (...)

  48. George Seli (2009). Fine-Grained Functionalism: Prospects for Defining Qualitative States. Philosophical Psychology 22 (6):765 – 783.score: 24.0
    Inverted spectrum and absent-qualia arguments have at least shown that giving the functional role of a qualitative state is challenging, as it is arguable that the same functional organization among one's inputs, outputs, and mental states can be preserved despite having one's qualia radically altered or eliminated. Sydney Shoemaker has proposed a promising strategy for the functionalist: defining a given qualitative state as being disposed to cause a belief that one is in such a state. Such beliefs would be (...)

    We derive the so-called Barbieri-Remiddi solution of the Bethe-Salpeter equation in QED in its general form and discuss its application to the bound-state energy spectrum.

    In recent papers the authors have discussed the dynamical properties of “large Poincaré systems” (LPS), that is, nonintegrable systems with a continuous spectrum (both classical and quantum). An interesting example of LPS is given by the Friedrichs model of field theory. As is well known, perturbation methods analytic in the coupling constant diverge because of resonant denominators. We show that this Poincaré “catastrophe” can be eliminated by a natural time ordering of the dynamical states. We obtain then a dynamical (...)
