An Experimental Study on the Effect of Domain Expertise on the Consistency of Relevance Judgements
Stacey Scholten,문성빈 한국정보관리학회 2021 정보관리학회지 Vol.38 No.3
An online experiment was conducted to test the subject-knowledge view of relevance theory in order to find evidence of a conceptual basis for relevance. Six experts in Library and Information Science (LIS), nine Master’s students of LIS, and twelve non-experts judged the relevance of 14 abstracts within and outside of the LIS domain. Consistency among the judges was calculated by joint-probability agreement (PA) and interclass correlation coefficients (ICC). When using PA to analyze the judgements, non-experts had a higher consensus regardless of the task or division of groups. However, ICC calculations found Master’s candidates had a higher level of consensus than non-experts within LIS, although the experts did not; and the agreement rates on the non-LIS task for all groups were only poor to moderate. It was only when the groups were analyzed as two groups (experts including Master’s candidates and non-experts) that the expected trend of higher consistency among experts in the LIS task was seen.
High-flux Cold Rubidium Atomic Beam for Strongly-coupled Cavity QED
Basudev Roy,Michael Scholten 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.61 No.3
This paper presents a setup capable of producing a high-flux continuous beam of cold rubidium atoms for cavity quantum electrodynamics experiments in the region of strong coupling. A 2D<sup>+</sup> magneto-optical trap (MOT), loaded with rubidium getters in a dry-film-coated vapor cell, fed a secondary moving-molasses MOT (MM-MOT) at a rate greater than 2 × 10<sup>10</sup> atoms/s. The MMMOT provided a continuous beam with a tunable velocity. This beam was then directed through the waist of a cavity with a length of 280 μm, resulting in a vacuum Rabi splitting of more than ±10 MHz. The presence of a sufficient number of atoms in the cavity mode also enabled splitting in the polarization perpendicular to the input. The cavity was in the strong coupling region, with an atom-photon dipole coupling coefficient g of 7 MHz, a cavity mode decay rate κ of 3 MHz, and a spontaneous emission decay rate Υ of 6 MHz.

Excitation functions of the reactions ^(55)Mn(p,n)^(55)Fe, ^(55)Mn(p,x)^(54)Mn and ^(55)Mn(p,x)^(51)Cr were measured from their respective thresholds up to 18 MeV in the first case and up to 45 MeV in the latter two cases, using the conventional stacked-foil technique. The radioactivity of ^(55)Fe was determined via high resolution X-ray spectrometry, both non-destructively and after radiochemical separation, and of the other radionuclides via high resolution γ-ray spectrometry. Nuclear model calculations were performed using the codes ALICE-IPPE, EMPIRE and TALYS. In some cases good agreement was found between the experimental and theoretical data while in others considerable deviations were observed. From the experimental data the integral yields of the three investigated radionuclides were calculated.
