A Causal Model for Integrating Workplace Spirituality into Hospitality Organizational Transformation

The purpose of this article is to explore the emerging construct of workplace spirituality and its application in hospitality organizational transformation. After a review of the literature, a causal model for workplace spirituality in organizational transformation is proposed. The goal of the research was to investigate linkages between dimensions of workplace spirituality, organizational transformation (defined as transformational leadership, organizational climate, and organizational learning capability), and work attitudes. The topic of workplace spirituality remains largely uncharted in the hospitality literature, offering researchers opportunities for new discoveries and hospitality organizations opportunities to improve their effectiveness

Searching for Anisotropic Cosmic Birefringence with Polarization Data from SPTpol

International audienceWe present a search for anisotropic cosmic birefringence in 500  deg2 of southern sky observed at 150 GHz with the SPTpol camera on the South Pole Telescope. We reconstruct a map of cosmic polarization rotation anisotropies using higher-order correlations between the observed cosmic microwave background (CMB) E and B fields. We then measure the angular power spectrum of this map, which is found to be consistent with zero. The nondetection is translated into an upper limit on the amplitude of the scale-invariant cosmic rotation power spectrum, L(L+1)CLαα/2π<0.10×10-4  rad2 (0.033  deg2, 95% C.L.). This upper limit can be used to place constraints on the strength of primordial magnetic fields, B1  Mpc<17  nG (95% C.L.), and on the coupling constant of the Chern-Simons electromagnetic term gaγ<4.0×10-2/HI (95% C.L.), where HI is the inflationary Hubble scale. For the first time, we also cross-correlate the CMB temperature fluctuations with the reconstructed rotation angle map, a signal expected to be nonvanishing in certain theoretical scenarios, and find no detectable signal. We perform a suite of systematics and consistency checks and find no evidence for contamination
