Ecosystems provide vital services that improve and support livelihoods and human well-being. Consequently, scientific research on ecosystem services (ES) has increased, over the past two decades globally, as well as in Africa. This study provides an overview of existing economic ES valuation methods in Africa using the Web of Science databases. The results highlighted that South Africa recorded the high number of ES valuation publications. The most evaluated ES category was provisioning then regulating services. In terms of economic valuation methods, the market price was the most popular, followed by the contingent valuation and the choice experiment methods. Recommendations are provided for future research in this filed.

This paper aims at examining how overtourism and tourismphobia are being approached as emergent research topics in current tourism literature. It conducts an analysis of 154 documents, indexed in the Web of Science (WoS) Core Collection and Scopus databases. The study follows a quantitative and qualitative approach, with the support of VOSviewer and HistCite softwares for a descriptive content analysis. The analysis focuses on highlighting important aspects in terms of the most frequent publication sources (authors and journals); co-citation, as well as dimensions and research streams; methodologies used; results obtained; and implications for future research. The literature review unveiled that the concepts of overtourism and tourismphobia are usually related to destinations’ development, negative impacts, and tourism policies and regulation. Results show that, although tourism excesses and conflicts have been studied for long, ‘overtourism’ and ‘tourismphobia’ have become usual terms, mainly within the past three years. Even though the adoption of the terms can be considered by some as a ‘trend’, the in-depth analysis of the topics shed light on how ‘old’ concepts can evolve to adapt to contemporary tourism issues. Further studies are needed in tracking the evolution of these topics and their implications on the future of tourism.

Although humans need ecosystems and ecosystem services for their survival and well-being, most of the global ecosystems and the services that they provide have declined and/or degraded rapidly over the past few decades. In order to find the ways to sustainably use natural resources, substantial efforts have been made to measure and value the ecosystem services. The term ‘ecosystem service’ was interpreted in different ways in the literature. For making correct decisions in natural resource management, a consistent way of defining and classifying ecosystem services is needed for valuation purposes. This paper argued for the need to divide ecosystem services into intermediate and final services.

Soil Ecosystem Services

Soil ecosystem services (ES) provide multiple benefits to human well-being, but the failure to appreciate them has led to soil degradation issues across the globe. Despite an increasing interest in the threats to soil resources, economic valuation in this context is limited. Importantly, most of the existing valuation studies do not account for the spatial distribution of benefits that soil ES provide to the population. In this study, we present the results of a choice experiment (CE) aimed at investigating spatial heterogeneity of attitudes and preferences towards soil conservation and soil ES. We explored spatial heterogeneity of both attitudes and welfare measures via GIS techniques. We found that citizens of the Veneto Region (Northeast Italy) generally have positive attitudes towards soil conservation. We also find positive willingness-to-pay (WTP) values for soil ES in most of the study area and a considerable degree of heterogeneity in the spatial taste distribution. Finally, our results suggest that respondents with pro-environmental attitudes display a higher WTP based on the geographic pattern of the distribution of WTP values and attitudinal scores across the area.

The COVID-19 pandemic has affected all aspects of society. Researchers worldwide have been working to provide new solutions to and better understanding of this coronavirus. In this research, our goal was to perform a Bibliometric Network Analysis (BNA) to investigate the strategic themes, thematic evolution structure and trends of coronavirus during the first eight months of COVID-19 in the Web of Science (WoS) database in 2020. To do this, 14,802 articles were analyzed, with the support of the SciMAT software. This analysis highlights 24 themes, of which 11 of the more important ones were discussed in-depth. The thematic evolution structure shows how the themes are evolving over time, and the most developed and future trends of coronavirus with focus on COVID-19 were visually depicted. The results of the strategic diagram highlight ‘CHLOROQUINE’, ‘ANXIETY’, ‘PREGNANCY’ and ‘ACUTE-RESPIRATORY-SYNDROME’, among others, as the clusters with the highest number of associated citations. The thematic evolution. structure presented two thematic areas: “Damage prevention and containment of COVID-19” and “Comorbidities and diseases caused by COVID-19”, which provides new perspectives and futures trends of the field. These results will form the basis for future research and guide decision-making in coronavirus focused on COVID-19 research and treatments.

Since the 21st century, the concept of green building has been gradually popularized and implemented in more countries, which has become a popular direction in the area of sustainability in the building industry. Over the past few decades, many scholars and experts have done extensive research on green building. The purpose of this paper is to systematically analyze and visualize the status quo of green building. Therefore, based on Web of Science (WoS), this paper analyzed the existing knowledge system of green building using CiteSpace, identified keywords related to green building and their frequency of occurrence using the function of keyword co-occurrence analysis, recognized five clusters using the function of cluster analysis, and explored the knowledge evolution pattern of green building using citation bursts analysis in order to reveal how research related to green building has evolved over time. On the basis of aforementioned keywords, clusters, and citation bursts analysis, this paper has built a knowledge graph for green building. This paper can help readers to better understand the status quo and development trend of green building and to easier recognize the shortcomings in the development of green building, so as to provide a promising direction for future research.

AbstractThis literature review deals with the understanding of ecosystem services related to the question of their applicability and appropriate methods for their valuation. We distinguish between ecological valuation methods that aim to assess the significance of landscape characteristics, conventional economic, i.e. monetary valuation and non-monetizing valuation or assessment. Ecological evaluation methods derive values by following a cost of production approach which neglects consumer preferences. Economic valuation methods focus on the exchange value of ecosystem services, i.e. they are based on consumer preferences, but do not adequately take into account the complex internal structure of ecosystems. We conclude that – from the view of implementation of ecosystem services for policy support and consulting – successful valuation approaches should particularly consider the relationships between economic, ecological and social aspects of ecosystem services’ provision.

Psychotherapy Interventions

The strong association between hope and optimal psychological functioning has been empirically demonstrated repeatedly over the past two decades. In an effort to capitalize on these associations, researchers have developed and tested hope interventions aimed to increase hopeful thinking and optimal psychological functioning. Results are promising, suggesting that hope is malleable and that hope therapy reduces symptoms of distress and increases in well-being. Further, hope has been examined as a predictor of treatment success and data suggest that those with higher hope may do better in various treatments than their low-hope counterparts and that changes in hope across the course of therapy are associated with simultaneous improvements in psychological functioning. In future research, it will be important to identify specific therapeutic interventions that predict increases in hope and to determine whether or not hopeful thought is a mechanism of change in psychotherapy interventions.
