The First Great Awakening: Revival and the Birth of a Nation

The First Great Awakening left an indelible mark on the development of America. With roots stretching back to the Christian Reformation of the 1500’s, the Great Awakening swept the young colonies with the fires of evangelical fervor. The revival shook the very foundations of colonial society. Following in its wake was a rebirth of reformed philosophy and theology that planted the seeds of self-government and political autonomy in the fertile soil of the Americas. By 1776, that seed had blossomed into a vibrant revolutionary movement that questioned the very fabric of Old World society. This article explores the rich Christian heritage of our nation by looking at the movement the inspired the American Revolution; the First Great Awakening. It explores at its theological foundations and its philosophical and social repercussions on the birth of the nation. Furthermore, this article examines the distinctly reformed character of the Awakening and the influence this had on the Founding generation

Neural signals encoding shifts in beliefs

Dopamine is implicated in a diverse range of cognitive functions including cognitive flexibility, task switching, signalling novel or unexpected stimuli as well as advance information. There is also longstanding line of thought that links dopamine with belief formation and, crucially, aberrant belief formation in psychosis. Integrating these strands of evidence would suggest that dopamine plays a central role in belief updating and more specifically in encoding of meaningful information content in observations. The precise nature of this relationship has remained unclear. To directly address this question we developed a paradigm that allowed us to decompose two distinct types of information content, information-theoretic surprise that reflects the unexpectedness of an observation, and epistemic value that induces shifts in beliefs or, more formally, Bayesian surprise. Using functional magnetic-resonance imaging in humans we show that dopamine-rich midbrain regions encode shifts in beliefs whereas surprise is encoded in prefrontal regions, including the pre-supplementary motor area and dorsal cingulate cortex. By linking putative dopaminergic activity to belief updating these data provide a link to false belief formation that characterises hyperdopaminergic states associated with idiopathic and drug induced psychosis

Enhancement of the quadrupole interaction of an atom with guided light of an ultrathin optical fiber

We investigate the electric quadrupole interaction of an alkali-metal atom with guided light in the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber. We calculate the quadrupole Rabi frequency, the quadrupole oscillator strength, and their enhancement factors. In the example of a rubidium-87 atom, we study the dependencies of the quadrupole Rabi frequency on the quantum numbers of the transition, the mode type, the phase circulation direction, the propagation direction, the orientation of the quantization axis, the position of the atom, and the fiber radius. We find that the root-mean-square (rms) quadrupole Rabi frequency reduces quickly but the quadrupole oscillator strength varies slowly with increasing radial distance. We show that the enhancement factors of the rms Rabi frequency and the oscillator strength do not depend on any characteristics of the internal atomic states except for the atomic transition frequency. The enhancement factor of the oscillator strength can be significant even when the atom is far away from the fiber. We show that, in the case where the atom is positioned on the fiber surface, the oscillator strength for the quasicircularly polarized fundamental mode HE$_{11}$ has a local minimum at the fiber radius $a\simeq 107$ nm, and is larger than that for quasicircularly polarized higher-order hybrid modes, TE modes, and TM modes in the region $a<498.2$ nm

Phase Space Reconstruction and Nonlinear Equilibrium Dynamics in the United States Beef Market

This paper investigates dynamic interactions in the US beef market using phase space reconstruction, which has been developed to analyze nonlinear dynamical systems. This approach provides important and unique empirical insights into consumers behavior in the beef market. Our results from a phase space reconstruction analysis demonstrate distinct differences between intertemporal short run impacts from food safety outbreaks (e.g., E. Coli) and longer run health effects (e.g., cholesterol). Adjustments due to factors such as cholesterol are permanent changes and do not affect the manner by which people consume, while consumers react to food safety scares by adjusting consumption for a short period of time and then returning to their normal steady state cycle of consumption.nonlinear time series, phase space reconstruction, food safety, health effects, Livestock Production/Industries, Marketing,

Molecular recognition on acoustic wave devices

Microporous thin films composed either of zeolite crystals embedded in sol-gel derived glass or of a molecular coupling layer, zeolite crystals and a porous silica overlayer, were formed on the gold electrodes of Quartz Crystal Microbalances (QCM). The microporosity of the thin films was characterized by in situ nitrogen and vapor sorption isotherms. Both preparation methods result in thin films with substantial microporosity. Selective adsorption based on molecular size exclusion from the microporous films could be achieved

The effect of rapid growth with fattening upon lactation in cattle and rats

A number of investigations have been made concerning the plane of nutrition just prior to parturition and during lactation and its effect on milk production, but very little work has been done to determine the effect of rapid growth with fattening on milk production in subsequent lactations. Such information is particularly pertinent for determining the most economical means of raising dairy heifers. Fattening or very rapid growth of dairy cattle would be a wasteful practice unless it resulted in lactation benefits. Common observation of dairy husbandmen has been that fat heifers seldom develop into high milk producers. This failure to milk well has often been blamed on inheritance rather than environmentor rearing intensity. It was considered important to determine the relative Importance of environment (feeding intensity) and heredity (inherent milking potential) as they affect fattening during growth and lactation development. Identical twin heifers were selected for experimental animals because of their identical inheritance, Littermate white rats were also used to determine the effect of rapid growth and fattening from weaning to parturition upon lactation in a second animal species
