We review the most relevant contributions to the abandonment option since the late 1960s. We begin by approaching the contributions to the literature before the emergence of the real options approach to capital investment decisions, and thereafter, under a consistent real options approach, highlighting the interactions between the option to abandon and other types of options. We then identify the methodologies adopted, and the business sectors/ types of investment projects where the abandonment option is more frequently studied. We also debate the strategic role of the abandonment solution in corporate divestitures and under a game-theoretical approach. Finally, we present some concluding remarks and identify how certain gaps found in the literature may constitute opportunities for future research.

Purpose
The purpose of this work is to validate and test for measurement invariance of the Motivation Scale for Sport Consumption (MSSC) across two samples of football fans from different countries (Turkey and Spain).

Methods
A confirmatory factorial analysis (CFA) was carried out on a sample of 668 respondents from Turkey and Spain, and on the two samples separately, followed by a measurement invariance of the MSSC across countries. Convergent validity was calculated by composite reliability and average variance extracted (AVE) values and discriminant validity by the square roots of the AVE values and its comparison with MSSC and SSIS dimensions’ cross-correlations.

Findings
The CFAs showed a good fit. The progressive country invariance test stated that configural, metric and scalar invariance across country produced a good model fit. CFI change between configural and metric invariance tests and between metric and scalar invariance tests is within the threshold of 0.01.

Practical Implications
This scale proves a robust instrument to measure the motivation to consume sport in the two studied samples.

Research Contribution
The article provides validated instruments for assessing fans’ motivations in the Turkish and Spanish populations. Further investigations based on more heterogeneous samples are necessary to confirm the models found.

Tourism has been fundamental for countries’ economic development, and Africa is the destination with the biggest tourism growth potential. Using 1414 travelers’ online reviews collected from TripAdvisor, the present work aims to understand which variables predict the satisfaction of Cape Verde’s hotel clients. Satisfaction was analyzed using sentiment analysis and ANOVA to predict the effect of the gathered variables on clients’ satisfaction. Results indicate that 90% of the clients revealed positive satisfaction and that nationality, date of stay, and previous traveler experiences affect satisfaction. Contrarily to our predictions, there is no statistically significant evidence that gender influences satisfaction. The findings of this study will help hotel marketing managers to align their strategies accordingly and meet their clients’ expectations.

Numerous valuable clients can be lost to competitors in the telecommunication industry, leading to profit loss. Thus, understanding the reasons for client churn is vital for telecommunication companies. This study aimed to develop a churn prediction model to predict telecom client churn through customer segmentation. Data were collected from three major Chinese telecom companies, and Fisher discriminant equations and logistic regression analysis were used to build a telecom customer churn prediction model. According to the results, it can be concluded that the telecom customer churn model constructed by regression analysis had higher prediction accuracy (93.94%) and better results. This study will help telecom companies efficiently predict the possibility of and take targeted measures to avoid customer churn, thereby increasing their profits.

Several studies explored the effect of Corporate Social Responsibility (CSR) on marketing. However, bibliometric research that organizes this production is scarce. Thus, this study aims to provide a bibliometric view of marketing-related CSR research, identifying this field’s state-of-the-art literature. Two thousand and forty-two articles were collected through the Web of Science (WoS) platform. Data were analyzed using VOSviewer software to map the data graphically. The results show that: (a) the literature on CSR in the marketing area is growing; (b) five articles alone accounted for 9940 citations, and there are several prolific authors; (c) the prominent journals identified in this research published 42.16% of the total; (d) The “Journal of Business Ethics” is the leader in the number of publications, followed by “Sustainability,” which has shown strong growth in recent years, and; (e) The US is the leading country, according to the number of articles and citations. The keyword trending network analysis revealed that CSR is becoming a strategic marketing approach for companies. This study offers an insight into the state-of-the-art and trends identification in CSR and marketing.
