AbstractPurpose -The purpose of this paper is to propose a comprehensive metric for customer engagement in Facebook, the top social networking site. Design/methodology/approach -The approach is conceptual and it makes operative customer engagement concept in the specific context that is Facebook. Findings -In the new dynamic business environment fostered by Internet, where customer value goes beyond what the customer spends on a brand or a firm, firms will be able to fine-tune their customer engagement strategy by means of the metric results and its evolution. Research limitations/implications -The paper, which provides insight and a metric for customer engagement in Facebook, is a starting point for future conceptual and empirical research that might be conducted to further refine the proposed metric. The assessment of engagement achieved as a result of actions on Facebook will allow marketers to evaluate the efficiency of the action and, through its longitudinal evaluation, the fluctuation according to different posting strategies used, so managers can see whether engagement or disengagement is happening and then make decisions about which type of content generates better engagement. Originality/value -The metric offered is unique, as it focuses on customer engagement on Facebook, and to the best of author's knowledge, there is not any previous attempt to measure it.

This research analyses residents' perceptions of the effects of tourism. Economic, cultural and environmental effects are identified as determinants of residents' attitudes towards tourism development and planning. Authors speculate that there are different patterns of resident's support depending on their differential benefits obtained from tourism. A conceptual model is developed and empirically tested in Santiponce, a small community in southern Spain. Our results support our basic hypothesis: resident's level of personal benefits obtained from tourism influence their perceptions regarding tourism impacts, and in consequence, their support for tourism development and for tourism planning.

The extent to which predatory journals can harm scientific practice increases as the numbers of such journals expand, in so far as they undermine scientific integrity, quality, and credibility, especially if those journals leak into prestigious databases. Journal Citation Reports (JCRs), a reference for the assessment of researchers and for grant-making decisions, is used as a standard whitelist, in so far as the selectivity of a JCR-indexed journal adds a legitimacy of sorts to the articles that the journal publishes. The Multidisciplinary Digital Publishing Institute (MDPI) once included on Beall’s list of potential, possible or probable predatory scholarly open-access publishers, had 53 journals ranked in the 2018 JCRs annual report. These journals are analysed, not only to contrast the formal criteria for the identification of predatory journals, but taking a step further, their background is also analysed with regard to self-citations and the source of those self-citations in 2018 and 2019. The results showed that the self-citation rates increased and was very much higher than those of the leading journals in the JCR category. Besides, an increasingly high rate of citations from other MDPI-journals was observed. The formal criteria together with the analysis of the citation patterns of the 53 journals under analysis all singled them out as predatory journals. Hence, specific recommendations are given to researchers, educational institutions and prestigious databases advising them to review their working relations with those sorts of journals.

Tourism represents one of the most important industries in the world and one of the sectors of fastest growth. An understanding of the relation between tourism and poverty is key for poverty reduction in developing countries. The impact of tourism on the reduction of both poverty and inequality in income distribution is analyzed in this paper in the Dominican Republic (within the Caribbean Community of Small Island Developing States). The Ng and Perron test for analyzing time series stationarity and the AutoRegressive Distributed Lag bounds test were used to determine the existence of long-term relationships. The shortrun dynamic models represented by the Error Correction Models were also estimated. The results showed that income from tourism has not alleviated poverty and has clearly failed to reduce inequality in the distribution of wealth. Finally, management implications are also provided for public and private bodies wishing to achieve sustainable tourism.

Tourist satisfaction is a key factor in tourism sustainability. A multiple mediation model is proposed to analyze the relationship between ecotourism knowledge and ecotourist satisfaction, assisting our understanding of the generative mechanism by which ecotourism knowledge influences ecotourist satisfaction. Ecotourists at the Natural Park Saltos de la Damajagua (Dominican Republic) were administered a questionnaire. The results (PLS-SEM) show that ecotourism site perceived value and attitudes towards ecotourism fully mediate the influence of ecotourism knowledge on ecotourist satisfaction. Ecotourism knowledge will therefore only have positive effects on ecotourist satisfaction when the ecotourism site is of high perceived value and there are positive attitudes towards ecotourism. 5000 bootstrap samples. 95% confidence interval. ***p < 0.001 (based on t(4999), one-tailed test) t(0.001, 4999) = 3.09. n.s: not significant. 210M.
