Knowledge and the Objection to Religious Belief from Cognitive Science
A large chorus of voices has grown around the claim that theistic belief is epistemically suspect since, as some cognitive scientists have hypothesized, such beliefs are a byproduct of cognitive mechanisms which evolved for rather different adaptive purposes. This paper begins with an overview of the pertinent cognitive science followed by a short discussion of some relevant epistemic concepts. Working from within a largely Williamsonian framework, we then present two different ways in which this research can be formulated into an argument against theistic belief. We argue that neither version work
Cross-Field Transport of Solar Energetic Particles in a Large-Scale Fluctuating Magnetic Field
The trajectories of Solar Energetic Particles (SEPs) in an Interplanetary
Magnetic Field (IMF) exhibiting large-scale fluctuations due to footpoint
motions originating in the photosphere, are simulated using a full-orbit
test-particle code. The cross-field transport experienced by the particles in
three propagation conditions (scatter-free, with scattering mean free path
lambda=0.3 AU and lambda=2 AU) is characterized in the Parker spiral geometry.
The role of expansion of the magnetic field with radial distance from the Sun
is taken into consideration in the calculation of particle displacements and
diffusion coefficients from the output of the simulations. It is found that
transport across the magnetic field is enhanced in the lambda=0.3 AU and
lambda=2 AU cases, compared to the scatter-free case. Values of the ratios of
perpendicular to parallel diffusion coefficients vary between 0.01 and 0.08.
The ratio of latitudinal to longitudinal diffusion coefficient perpendicular to
the magnetic field is typically 0.2, suggesting that transport in latitude may
be less efficient.Comment: 17 pages, 11 figure
Web Single Sign-On Authentication using SAML
Companies have increasingly turned to application service providers (ASPs) or Software as a Service (SaaS) vendors to offer specialized web-based services that will cut costs and provide specific and focused applications to users. The complexity of designing, installing, configuring, deploying, and supporting the system with internal resources can be eliminated with this type of methodology, providing great benefit to organizations. However, these models can present an authentication problem for corporations with a large number of external service providers. This paper describes the implementation of Security Assertion Markup Language (SAML) and its capabilities to provide secure single sign-on (SSO) solutions for externally hosted applications
