Towards an international understanding of the power of celebrity persuasions: a review and a research agenda
Research into advertising using celebrity has been undertaken for nearly 40 years. It has
principally used surveys and experiments to explore how consumers respond to celebrity
advertisements. A recent meta-study of 32 papers has demonstrated that different
populations respond in different ways to celebrity endorsements. Specifically, both US
subjects and college students are more likely to respond in a significant way to the
presence of celebrity than subjects who are not from the US, or who are not studying at
college. Given that the nationality and student status of subjects matter, this article
explores the make up of the samples that have been used to examine celebrity advertising.
The article finds that these samples are not representative of US populations
(because so many are students), nor of populations outside the US (because so few
live beyond it). Furthermore, the history of dominance of US-based student samples, and
the citation practices which keep them circulating in academia, suggests that theories of
celebrity advertising have for a long time been excessively influenced by ideas tested on
this unrepresentative group. This fact will limit the applicability of research into celebrity
advertising to the wider world. I explore whether this matters, and how deficiencies
might be addressed in further research

Not AvailableBacterial metabolites are one of the primary sources of drugs that we currently use to treat several diseases. However, bacterial drug discovery and development is a challenging and time-consuming process, and the emergence of new diseases and the development of resistance to currently available drugs demand the discovery of new metabolites with better biological activities. The new advancements in microbial technology, omics, genome and metabolic engineering, synthetic biology and the interdisciplinary approach of these fields overcome the hurdles in drug discovery and heterologous synthesis from bacteria. The gut microbiome performs a vital role in sustaining human health and aids in tackling various diseases. The metabolites produced by the gut microbiome act as an energy source for colon epithelium, maintain pH, help in cell differentiation and induces apoptosis in abnormal cells. The review discusses about the bacterial derived bioactive compounds, advancements and technologies in bacterial synthesis of bioactive sources and genomic and synthetic biology methods for the bioprospecting of bacterial metabolites. Since the gut microbiome relates to colon health, we have also discussed the techniques comprising probiotics, prebiotics, microbiome transplantation, toxins, and bacteriocins capable of preventing and managing colon associated health condition. Future directions in bacterial bioactive metabolite production are also discussed.Not Availabl
