This study evaluates bibliometric analysis of sustainable tourism in the open innovation realm, depicts emerging themes, and offers critical discussion for theory development and further research. Through the use of bibliometrix, this paper investigates the amount of studies conducted in this area and verifies if such studies have represented a contribution to the evolving research in the field of sustainable tourism. Specifically, the paper identifies whether and to what extent scholars have explored these interconnections and maps to get to a conceptual structure of the field under investigation. The results identify the development status and the leading trends in terms of impact, main journals, papers, topics, authors, and countries. The analysis and the graphical presentations are crucial, as they can help both researchers and practitioners to better understand the state of the art of sustainable tourism in the experiential and digital era.

Purpose This study aims to examine the factors influencing tourists to share their travel experiences on social media (SM). Design/methodology/approach An online questionnaire was administered to 1,280 American travelers, and the data were analyzed using partial least squares structural equation modeling (PLS-SEM). Findings The PLS-SEM results indicated that non-participant sharing had a direct and positive effect on tourists’ tendencies to share their travel experiences on SM. Environmental, relational and security concerns had direct and negative effects on actual travel-experience sharing, whereas altruism, personal fulfillment and self-actualization had direct and positive effects on actual travel-experience sharing. Practical implications Travelers were found to attach importance to content shared on SM when they believed the content to be objective and reliable and were more likely to share such content on their own SM accounts. This finding suggests that tourist-created content is crucial. Tourism businesses, therefore, should reduce or eliminate inhibitory factors to increase content sharing. This research provides guidance for tourism businesses’ SM initiatives. Originality/value The study, first, contributes to an understanding of the factors affecting the sharing of travel experiences on SM. Second, this study develops a holistic approach that integrates the factors that might affect tourists’ SM content-sharing behavior into a single model.

This paper investigates the main elements that can influence customer satisfaction in tourist services, with specific reference to tourism industry. The importance of this topic resides in the fact that tourists' positive experiences of service, products, and other resources provided by tourism destinations can produce customer retention as well as positive word-of-mouth. Indeed, satisfaction with travel experiences contributes to destination loyalty. The degree of tourists' loyalty to a destination is reflected in their intentions to revisit the destination and in their recommendations to others. Thus, information about tourists' loyalty is important to destination marketers and managers in order to sustain destination attractiveness. Although predominant literature has adopted a demand-side perspective, this paper analyses tourist satisfaction according to an overlapping perspective that contemplates both the demand and the offer side where this latter, in the wider meaning, also includes the systemic perspective. More precisely, this paper aims to identify the principle competitive strategies that the variety of stakeholders, cooperating together in a destination, has to implement in order to increase tourist satisfaction and loyalty. Indeed, the point of view of this paper is to understand how destination attributes and services affect the tourist satisfaction. In order to study the link between destination attributes and tourist satisfaction, the paper collects cross-sectional data via questionnaire, from May 2012 to May 2013. The adopted approach allows to individuate the factors that can influence tourist satisfaction, their (positive or negative) direction and their magnitude. This paper uses 14 tourist satisfaction indicators in order to measure the global satisfaction. Furthermore, this study allows to identify the current strengths and weaknesses of the tourist offer. In particular, the study paid attention to the phase of service delivery since it is the time when customer satisfaction is generated. From this study, it comes out that tourist satisfaction depends on a complex process where the role of each actor is fundamental and it must be in tune with all the other ones. Findings show that tourists visiting Naples are not completely satisfied, supporting that Naples has not a clear destination image.

Purpose Over the past few years, several scholars have focused on innovation strategies with specific regard to family food firms. In line with this research stream, the purpose of this paper is to understand how family food firms with long-standing traditions can implement innovative productions while remaining anchored to the past. Design/methodology/approach By adopting a qualitative research methodology, mainly based on a multiple case study, this paper seeks to cover some unexplored areas regarding the opportunity of combining tradition and innovation to achieve success in the highly competitive international arena in which family food firms operate. The authors analyze the cases of “La Torrente,” “Cioccolatitaliani” and “La Fabbrica della Pasta di Gragnano.” Findings Successful family food firms leverage their deep-rooted knowledge of both family and local traditions to innovate. At same time, they establish continuous info exchange flows with all of the firm’s stakeholders by adopting an open innovation approach. Research limitations/implications From a theoretical perspective, there is a need for an in-depth study of how an effective blend of tradition and innovation is formalized, above all, in family firms. As for the practical implications, all the three case studies represent a best practice, especially for family firms with a long-standing history and strong local connections. Practical implications The paper shows how important it is to keep traditional factors in food industry and offers hints and suggestions to decision makers of family firms on how to valorize, in terms of competitiveness, their traditional resources – almost bound to their territory with innovation tools and processes. Social implications The paper is interesting because it offers an analysis of a specific group of firms – family firms – that characterize many industries in Italy and in Europe. Although often small, these firms can show dynamism and creativity. The paper offers hints on how to approach innovation in the sector while keeping the value of tradition. Originality/value The originality of the proposed conceptual model stems from the need to overcome the previous theoretical models, which deal separately with sources of past knowledge and sources of new and/or external knowledge.

Tackling hunger is a challenge for many African governments because of its endemic nature on the continent. Many African countries have found it difficult to achieve significant reductions in hunger and malnutrition since 1990. In this paper, we review the progress of African countries in the fight against hunger over the past three decades, using the Global Hunger Index (GHI) scores. Ghana had the best GHI improvement (-53.1%) while Zimbabwe and Central African Republic had slightly increased GHI scores (+1.6%). Within this time period, few countries had significant reductions in their GHI scores, while some suffered increases. Furthermore, in assessing the three indicators of GHI: (i) prevalence of undernourishment (percent population), (ii) prevalence of stunting in children (%) and (iii) prevalence of wasting in children (%), we found that no country in Africa was able to achieve all three targets. Six countries (Tunisia, Ghana, South Africa, Morocco, Mauritius and Algeria) were able to achieve targets for two of these while the majority achieved only one. We present country-level evidence of clear links between GHI scores with score for human development, social protection and terrorism. Some challenges that made the zero hunger target a difficult task in Africa are reviewed while opportunities for moving the continent towards the zero-hunger target by 2030 are also explored.
