Availability of fresh water for crop irrigation is becoming scarce and rather expensive. In this context, the research about the potential reutilization of non-conventional water sources becomes highly relevant, principally in arid and semi-arid areas. On many occasions, these new water resources involve water with a moderate concentration of salt, making it necessary to improve plant growth under moderate saline conditions. Besides plant breeding techniques, the use of molecules able to improve plant adaptation to saline conditions has great interest. Between these molecules, humic substances (HS) have proven to be efficient as stress-protectors under specific conditions of stress intensity and moment of application. The HS are main components of the soil organic matter and dissolved organic matter resulting from the biotic and abiotic transformation of fresh organic matter in natural ecosystems. Although knowledge about their structure is still under open debate, HS contain aromatic and aliphatic domains presenting O-, N- and S- containing functional groups with high biological and chemical activities. The aim of this presentation is to summarize the main effects of humic acids (HA) applied either on the root or on the shoot, on the metabolism and hormonal balance of plants cultivated under normal and stressing conditions, from studies carried out for our group and collaborations during the last years. Summarizing, all these results show HA as a promising tool for improving crop adaptation to irrigation using moderate saline water sources.
Who’s asking? Social platform and research sponsors’ identity biases in guests’ hospitality experience-reviews: a case study of Spanish hotels
(Taylor and Francis, 2023) Woodside, A.G. (Arch G.); Mir-Bernal, P. (Pedro); Sadaba-Garraza, T. (Teresa); San-Miguel-Arregui, P. (Patricia)
The study here assesses the systematic variability of service performance assessments in customer reviews placed in alternative online social media platforms in the travel industry as well as responses to the firm’s requests for customer evaluations. The research includes an empirical study conducted by a national (Spanish) hotel chain of nine corporately-owned properties (hotels). Data-analyses were performed of data collected for the nine hotels from TripAdvisor and Booking.com, as well as internal data from the hotel chain’s customer data files. The findings support the general conclusion that hotel reviews on different social media platforms vary in systematic ways. TripAdvisor reviews consistently include the largest share of detractors across all social media platforms in this study, ranging from 11 to 51%. This study contributes useful benchmarks for the relative differences in performances in customer experience assessments across different social media platforms.
