The host–guest molecules are often used in various fields and applications. This paper aims to discuss the role of host–guest complexes in the textile industry, focusing on calixarenes as a potential adsorbent for hazardous dyes. The paper begins with an introduction to nanotechnology and its many uses, including textiles.

The risks associated with the utilisation of dyes and its adverse effects on the environment are then also highlighted. This paper also discusses the structure and characteristics of calixarenes and their potential use as an adsorbent to extract toxic metals from aqueous solutions. The paper also explains the molecular structure of calixarenes, especially the ability of its upper and lower rims, which can be altered to yield derivatives with various selectivities for diverse guest ions and small molecules. In addition, the application of various host–guest molecules in the textiles industry to extract dyes also had been discussed.

In conclusion, the paper highlights the essential in establishing a systematic review on the significance of selective adsorbents, such as calixarenes, to isolate particular targets from diverse matrices in the textile industry.

Only discussing several applications for several host–guest molecules.

The paper concisely describes various host–guest molecule applications in the textile industry, with each molecule being elaborated upon in detail.

Focusing on critical discourse analysis, this paper aims to propose a framework for analysing the way activist anti-tourism groups construct their social action of protest. The authors argue that activist groups use different narrative strategies to construct and legitimise their discourse of protest to convey social meanings for social action practices. This study represents an attempt to explain how anti-tourism activist groups have the agency to build different paradigms of protest rooted in particular views of tourism.

As a result of the lack of research in this area, this study used a comparative case study methodology drawn on four case studies in the field of anti-tourism protest. Case study is deemed adequate to explore a complex social phenomenon, how activist groups differ from each other, in a specific socio-economic context. A critical discourse analysis method is used to study primary (interviews) and secondary sources (reports, websites and online campaigns documents) of information, which express the activist group motivations and objectives to protest against tourism.

This study’s findings provide evidence in how discourse differs among the protest groups. Three narrative paradigms of protest are identified, which guide their agency: scepticism, based on a global and ecological approach; non-interventionist transformation, rooted in local community issues; and direct transformation, based on a sectoral problem-solving approach. These differences are interpreted as the consequences of the emergence and the development of different paths of protest according to specific social contexts and power relations in which anti-tourism groups are embedded.

This paper provides a contemporary approach to anti-tourism activism within the context of social movements. This case study may be of interest to practitioners and international destination managers interested in gaining a better understanding of anti-tourism protest strategies, new anti-tourism narratives following COVID-19 and the opportunities and challenges for opening a dialogue with those involved in activism and social urban movements as part of sustainable tourism governance. Our results can also help activists to rethink how they integrate differences and particular strategic positions to avoid hindering collective action. This knowledge is especially useful for managers and authorities seeking to develop more accurate collaborative governance practices with local activists, and especially those interested in fostering participative action without marginalising the diverse range of local community perspectives.
