Service-Dominant Logic: Premises, Perspectives, Possibilities

Abstract: In 2004, Robert F. Lusch and Stephen L. Vargo published their groundbreaking article on the evolution of marketing theory and practice toward 'service-dominant (S-D) logic', describing the shift from a product-centred view of markets to a service-led model. Now, in this keenly anticipated book, the authors present a thorough primer on the principles and applications of S-D logic. They describe a clear alternative to the dominant worldview of the heavily planned, production-oriented, profit-maximizing firm, presenting a coherent, organizing framework based on ten foundational premises. The foundational premises of S-D logic have much wider implications beyond marketing for the future of the firm, transcending different industries and contexts, and will provide readers with a deeper sense of why the exchange of service is the fundamental basis of all social and economic exchange. This accessible book will appeal to students, as well as to researchers and practitioners.

Tau neutrinos favored over sterile neutrinos in atmospheric muon neutrino oscillations.

Abstract: The previously published atmospheric neutrino data did not distinguish whether muon neutrinos were oscillating into tau neutrinos or sterile neutrinos, as both hypotheses fit the data. Using data recorded in 1100 live days of the Super-Kamiokande detector, we use three complementary data samples to study the difference in zenith angle distribution due to neutral currents and matter effects. We find no evidence favoring sterile neutrinos, and reject the hypothesis at the $99%$ confidence level. On the other hand, we find that oscillation between muon and tau neutrinos suffices to explain all the results in hand.

Constraints on Cosmological Models from Hubble Space Telescope Observations of High-z Supernovae

Abstract: We have coordinated Hubble Space Telescope (HST) photometry with ground-based discovery for three supernovae: Type Ia supernovae near z ≈ 0.5 (SN 1997ce, SN 1997cj) and a third event at z = 0.97 (SN 1997ck). The superb spatial resolution of HST separates each supernova from its host galaxy and leads to good precision in the light curves. We use these light curves and relations between luminosity, light-curve shape, and color calibrated from low-z samples to derive relative luminosity distances that are accurate to 10% at z ≈ 0.5 and 20% at z = 1. When the HST sample is combined with the distance to SN 1995K (z = 0.48), analyzed by the same precepts, we find that matter alone is insufficient to produce a flat universe. Specifically, for Ωm+ΩΛ = 1, Ωm is less than 1 with more than 95% confidence, and our best estimate of Ωm is -0.1±0.5 if ΩΛ = 0. Although this result is based on a very small sample whose systematics remain to be explored, it demonstrates the power of HST measurements for high-redshift supernovae.
