Catholicity in the Lutheran ministry

The second of two articles (for the first article see Consensus 5,23-28 o 79) dealing with the history and tradition of the Lutheran ministry, this article demonstrates that the centrality of the doctrine of justification, as understood by the Reformers, does not interrupt but undergirds the historic continuity of a Lutheran understanding of the ministry. Support for this view is found in the self-understanding of the Augsburg Confession, which links its articulation of the Christian faith to the great consensus expressed in the classic Christian creeds and affirmed in the centrality of the Pauline doctrine of justification

Job Separations, Job Loss and Informality in the Russian Labor Market

Having unique data we investigate the link between job separations (displacement and quits) and informal employment, which we define in several ways posing the general question whether the burden of informality falls disproportionately on job separators in the Russian labor market. After we have established positive causal effects of displacement and quits on informal employment we analyze whether displaced workers experience more involuntary informal employment than their non-displaced counterparts. Our main results confirm our contention that displacement entraps some of the workers in involuntary informal employment. Those who quit, in turn, experience voluntary informality for the most part, but there seems a minority of quitting workers who end up in involuntary informal jobs. This scenario does not fall on all the workers who separate but predominantly on workers with low human capital. We also pursue the issue of informality persistence and find that informal employment is indeed persistent as some workers churn from one informal job to the next. Our study contributes to the debate in the informality literature regarding segmented versus integrated labor markets. It also contributes to the literature on displacement by establishing informal employment as an important cost of displacement. We also look at the share of undeclared wages in formal jobs and find that these shares are larger for separators than for incumbents, with displaced workers bearing the brunt of this manifestation of informality.

Two-photon transport through a waveguide coupling to a whispering gallery resonator containing an atom and photon-blockade effect

We investigate the two-photon transport through a waveguide side-coupling to a whispering-gallery-atom system. Using the Lehmann-Symanzik-Zimmermann (LSZ) reduction approach, we present the general formula for the two-photon processes including the two-photon scattering matrices, the wavefunctions and the second order correlation functions of the out-going photons. Based on the exact results of the second order correlation functions, we analyze the quantum statistics behaviors of the out-going photons for two different cases: (a) the ideal case without the inter-modal coupling in the whispering gallery resonator; (b) the case in the presence of the inter-modal coupling which leads to more complex nonlinear behavior. In the ideal case, we show that the system consists of two independent scattering pathways, a free pathway by a cavity mode without atomic excitation, and a "Jaynes-Cummings" pathway described by the Jaynes-Cummings Hamiltonian of a single-mode cavity coupling to an atom. The free pathway does not contribution to correlated two-photon processes. In the presence of intermodal mixing, the system no longer exhibit a free resonant pathway. Instead, both the single-photon and the two photon transport properties depend on the position of the atom. Thus, in the presence of intermodal mixing one can in fact tune the photon correlation properties by changing the position of the atom. Our formalism can be used to treat resonator and cavity dissipation as well.Comment: 9 pages, 7 figure
