A historical review is presented of the Social Science Quarterlv from its inception in 1920 until 1970. Some of the signif events in the history of the Quarterly are related to the broader soc & academic contexts in which they occurred. Originally, the journal had only 114 subscribers (including libraries). In the first 3 yrs it was primarily a journal of pol'al sci. In 1923 the journal was renamed the Southwestern Political & Social Science Quarterly, but most articles were still by pol'al sci'ts. In 1926 the journal became more interdisciplinary when an economist became co-Ed. In 1929 articles were published by 5 econ'ts who were to become presidents of the Amer Econ Assoc. All contributed work of high quality & unusual interdisciplinary appeal. In 1930, sociol articles began to appear. But in Mar 1931 the Quarterly had only 302 subscribers & had fiscal troubles. In 1930 it was proposed that the soc sci's be given more space & the name of the journal be changed to The Southwestern Economic & Social Science Quarterly. There was conflict over this, the journal's name was not changed, but soc sci won. During the period 1931-1968 emphasis was given to res on southwestern subjects & throughout the 30's regional articles & authors dominated. In the 40's the focus was on war subjects, circulation declined, & an attempt to place the journal in a more secure status by offering the U of Texas co-publishership did not get off the ground. In the 50's membership began to reach pre-war levels again, but was no higher than 4 decades earlier. By 1970 U of Texas support helped to produce a technically superior journal. During the early 60's the outstanding content was substantively non-regional yet stimulated by southwestern scholars. By 1968, the Quarterly had 1,948 subscribers; by 1970, 2,600, & the opportunity to select from among more than 300 submitted manuscripts. M. Maxfield.

One important building block for future integrated nanophotonic devices is the scalable on-chip interfacing of single photon emitters and quantum memories with single optical modes. Here we present the deterministic integration of a single solid-state qubit, the nitrogen-vacancy (NV) center, with a photonic platform consisting exclusively of SiO2 grown thermally on a Si substrate. The platform stands out by its ultra-low fluorescence and the ability to produce various passive structures such as high-Q microresonators and mode-size converters. By numerical analysis an optimal structure for the efficient coupling of a dipole emitter to the guided mode could be determined. Experimentally, the integration of a preselected NV emitter was performed with an atomic force microscope and the on-chip excitation of the quantum emitter as well as the coupling of single photons to the guided mode of the integrated structure could be demonstrated. Our approach shows the potential of this platform as a robust nanoscale interface of on-chip photonic structures with solid-state qubits. ; European Fund for Regional Development of the European Union ; Bundesministerium für Bildung und Forschung https://doi.org/10.13039/501100002347 ; Peer Reviewed
