Extending insights from Cox's interactional model of cultural diversity [Cox, T. H., Jr. 1994. Cultural Diversity in Organizations: Theory, Research and Practice. Berett-Koehler, San Francisco], we examine the influence of diversity climate on customer satisfaction, a key business-unit outcome. In addition, we explore service climate and minority and female representations as boundary conditions of the diversity climate–customer satisfaction relationship. Utilizing longitudinal data from 59,592 employees and 1.2 million customers of 769 store units of a large U.S. national retail organization, the results reveal that, as hypothesized, diversity climate is positively and significantly related to customer satisfaction measured a year later. Moreover, the diversity climate–customer satisfaction relationship is most strongly positive in predominately minority, highly pro-service store units, whereas female representation exhibits null moderating effects. These findings have important research and practical implications.

We used 4-yr baseline Hubble Space Telescope/Wide Field Camera 3 IR observations of the Galactic Centre in the F153M band (1.53 μm) to identify variable stars in the central ~2.3 arcmin × 2.3 arcmin field.We classified 3845 long-term (periods from months to years) and 76 short-term (periods of a few days or less) variables among a total sample of 33 070 stars. For 36 of the latter ones, we also derived their periods (< 3 d). Our catalogue not only confirms bright long period variables and massive eclipsing binaries identified in previous works but also contains many newly recognized dim variable stars. For example, we found δ Scuti and RR Lyrae stars towards the Galactic Centre for the first time, as well as one BL Her star (period < 1.3 d). We cross-correlated our catalogue with previous spectroscopic studies and found that 319 variables have well-defined stellar types, such as Wolf-Rayet, OB main sequence, supergiants and asymptotic giant branch stars. We used colours and magnitudes to infer the probable variable types for those stars without accurately measured periods or spectroscopic information. We conclude that the majority of unclassified variables could potentially be eclipsing/ellipsoidal binaries and Type II Cepheids. Our source catalogue will be valuable for future studies aimed at constraining the distance, star formation history and massive binary fraction of the Milky Way nuclear star cluster. © 2017 The Authors. ; The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP7/2007-2013) / ERC grant agreement no [614922].
