The current study examines the effects of a bottom-up CSR approach, as compared to a top-down CSR approach, on consumer publics' evaluation of CSR practices. By applying dialogic communication as a theoretical lens, this study also investigates the mediating effects of perceived dialogic organizational – employee communication in such relationships. Through a between-subject online experiment, the results showed that when a CSR program was implemented with a bottom-up approach (vs. a top-down approach), consumer publics perceived a higher level of organization – employee dialogic communication. Such perception, in turn, results in consumer publics' favorable attitude toward the company, purchase intentions, and supportive behavioral intentions of CSR practices. In addition, the positive effects of the bottom-up CSR approach on consumer publics' corporate evaluations via the mediation of perceived dialogic organization – employee communication were greater for individuals with higher levels of corporate distrust than those with lower levels of corporate distrust. The study extends our understanding of the value of dialogic communication in public relations and CSR communication. [ABSTRACT FROM AUTHOR]

Purpose: Whether and how the oral microbiome and its changes in allogeneic hematopoietic cell transplantation (alloHCT) recipients may contribute to oral chronic GVHD (cGVHD) pathogenesis is unknown. In addition, although the oral and colonic microbiota are distinct in healthy adults, whether oral microbes may ectopically colonize the gut in alloHCT patients is unknown., Experimental Design: To address these knowledge gaps, longitudinal oral and fecal samples were collected prospectively in the multicenter Close Assessment and Testing for Chronic GVHD study (NCT04188912). Through shotgun metagenomic sequencing of the samples collected at baseline, oral cGVHD onset, first post-cGVHD onset visit, and 1-year post-HCT time points in patients with oral cGVHD (cases; N = 29) or without any cGVHD (controls; N = 51), we examined whether (i) oral and/or gut microbiomes and their longitudinal trajectories differ between cases and controls and (ii) oral and gut microbiomes overlap in alloHCT recipients, especially those developing cGVHD., Results: A total of 195 samples were analyzed. The onset of oral cGVHD was characterized by an expansion of Streptococcus salivarius and Veillonella parvula in the oral microbiome. High levels of oral/gut microbiota overlap were observed, particularly in patients with oral cGVHD, suggesting ectopic colonization of the gut by oral bacteria., Conclusions: The unusual coalescence of two distant niches in these patients may result in short- or long-term consequences for the host, a novel avenue for future research. In addition, this study suggests a contribution of the oral microbiome to oral cGVHD pathogenesis., (©2024 American Association for Cancer Research.)
