Sharing and obtaining information over social media has enabled people to express their opinions regarding any event. Since the tweets regarding the Russia-Ukraine war were extensively publicized on social media, this study aims to analyse the temporal sentiments people express through tweets related to the war.

Relevant hashtag related to the Russia-Ukraine war was identified, and tweets were downloaded using Twitter API, which were later migrated to Orange Data mining software. Pre-processing techniques like transformation, tokenization, and filtering were applied to the extracted tweets. VADER (Valence Aware Dictionary for Sentiment Reasoning) sentiment analysis module of Orange software was used to categorize tweets into positive, negative and neutral ones based on the tweet polarity. For ascertaining the key and co-occurring terms and phrases in tweets and also to visualize the keyword clusters, VOSviewer, a data visualization software, was made use of.

An increase in the number of tweets is witnessed in the initial days, while a decline is observed over time. Most tweets are negative in nature, followed by positive and neutral ones. It is also ascertained that tweets from verified accounts are more impactful than unverified ones. russiaukrainewar, ukraine, russia, false, war, nato, zelensky and stoprussia are the dominant co-occurring keywords. Ukraine, Russia and Putin are the top hashtags for sentiment representation. India, the USA and the UK contribute the highest tweets.

The study tries to explore the public sentiments expressed over Twitter related to Russia-Ukraine war.

The study aims to showcase the developmental perspective of “grey literature” and its importance to different sectors of the society. Furthermore, issues, challenges and possibilities concerned with the existence of “grey literature” have also been discoursed.

The study is based on the existing literature published in the field of “grey literature” which was identified with the aid of three leading indexing and abstracting services, Web of Science, SciVerse Scopus, and Google Scholar. Keywords like grey literature, black literature, The Grey Journal, The International Journal on Grey Literature, International Conference on Grey Literature, non-conventional literature, semi-published literature, System for Information on Grey Literature in Europe (SIGLE), European Association for the Exploitation of Grey Literature (EAGLE), white literature, white papers, theses and dissertations, GreyNet, grey literature-electronic media, Grey market, open access, OpenNet, open access repositories, institutional repositories, open archives, electronic theses and dissertations, institutional libraries, scholarly communication, access to knowledge, metadata standards for grey literature, metadata heterogeneity, disciplinary grey literature, etc. were searched in the select databases. Simple as well as advanced search feature of the databases were made use of. Moreover, for more recent and updated information on the topic, the “citing articles” feature of the databases was also used. The “citing articles” were consulted on the basis of their relevance with the subject content.

The study helps to understand the definitive framework and developmental perspective of “grey literature”. “Grey Literature” has emerged as a promising content for enhancing the visibility of the ideas that were earlier unexplored and least made use of “Grey literature” has also overcome the problems and issues with its existence and adoption. Technology has played a catalytic role in eradicating the issues and problems pertinent to the “grey literature” to a greater extent.

The study is based on the published literature that is indexed by only three databases, i.e. Web of Science, SciVerse Scopus and Google Scholar. Furthermore, some limited aspects of “grey literature” have been covered.

The study will be of great help to various stakeholders and policymakers to showcase the value and importance of “grey literature” for better access and exploitation. It will also be of importance to those interested to know how the literature tagged as grey changed with the passing time and how it through its unseen characteristics has evolved as an important source of information at par with the “white literature”.

The study tries to provide a demarcated and segregated outlook of the “grey literature”. It also focuses on various issues, problems and possibilities pertinent to the adoption and existence of “grey literature”.

The study showcases the social impact (online attention) of funded research compared to nonfunded for the BRICS nations. The key themes achieving online attention across the funded and nonfunded publications have also been identified.

A total of 1,507,931 articles published across the BRICS nations for a period of three (03) years were downloaded from the Clarivate Analytics' InCites database of Web of Science (WoS). “Funding Acknowledgement Analysis (FAA)” was used to identify the funded and nonfunded publications. The altmetric score of the top highly cited (1%) publications was gauged from the largest altmetric data provider, “Altmetric.com”, using the DOI of each publication. One-way ANOVA test was used to know the impact of funding on the mentions (altmetrics) across different data sources covered by Altmetric.com. The highly predominant keywords (hotspots) have been mapped using bibliometric software, “VOSviewer”.

The mentions across all the altmetric sources for funded research are higher compared to nonfunded research for all nations. It indicates the altmetric advantage for funded research, as funded publications are more discussed, tweeted, shared and have more readers and citations; thus, acquiring more social impact/online attention compared to nonfunded publications. The difference in means for funded and nonfunded publications varies across various altmetric sources and nations. Further, the authors’ keyword analysis reveals the prominence of the respective nation names in publications of the BRICS.

The study showcases the utility of indexing the funding information and whether research funding increases social impact return (online attention). It presents altmetrics as an important impact assessment and evaluation framework indicator, adding one more dimension to the research performance. The linking of funding information with the altmetric score can be used to assess the online attention and multi-flavoured impact of a particular funding programme and source/agency of a nation so that necessary strategies would be framed to improve the reach and impact of funded research. It identifies countries that achieve significant online attention for their funded publications compared to nonfunded ones, along with the key themes that can be utilised to frame research and investment plans.

The study represents the social impact of funded research compared to nonfunded across the BRICS nations.

The purpose of this study is to identify factors instrumental in developing entrepreneurial intentions among youth. Although, numerous studies have been conducted focusing on entrepreneurship intention, however, this study attempts to provide an integrated model by means of analyzing the impact of internal (personal) and external (environmental) factors in developing entrepreneurial intentions.

This cross-sectional study is based on primary and secondary data. A sample of 358 respondents belonging to the age group of 21–25 years from various universities and colleges in Kashmir participated in the study. Primary data collection was done using self-administered questionnaires. A purposive sampling approach was used to identify respondents for the current study. Structural equation modeling has been used for testing hypotheses besides other statistical methods and techniques.

The study identifies three important antecedents of entrepreneurship intentions, namely, personal competencies, contextual factors and entrepreneurial exposure and tests the relationships using path analysis. It further suggests that there exists a significant relationship between personal competencies, entrepreneurial exposure, contextual elements and entrepreneurial intention.

The paper presents an integrated and comprehensive model of entrepreneurial intentions discussing important antecedents instrumental in developing entrepreneurship intentions among youth considering both personal and environmental factors. It is, therefore, an important contribution toward entrepreneurship literature and of interest to different policymakers and institutions related to entrepreneurship.

The prevailing overconsumption issue in the hotel industry is attributable mainly to the irresponsible consumption behaviour of hotel guests. In parallel with Islamic principles, which advocate abstinence from excess consumption and frugality, the “waste not, want not” notion can be considered as one of the effective solutions to this problem. However, little is known about the factors that drive frugality amongst Muslim tourists. In addressing this gap, this study aims to predict the effect of environmental advertising and green attitude on frugality in the context of the Malaysian hotel industry. The study also tests the mediating role of the green attitude between environmental advertising and frugality. Furthermore, it examines the role of price consciousness as a moderator of the green attitude-frugality link.

The stimulus-organism-response theory was used to develop the conceptual framework of this study. A cross-sectional method was used to collect 222 usable questionnaires from Muslim tourists in Malaysia. The hypothesised relationships were tested using the structural equation modelling, partial least squares approach.

The study found support for the direct effect of environmental advertising and green attitude on frugality. It also confirmed the mediating effect of the green attitude in the environmental advertising-frugality link. However, price consciousness did not moderate the relationship.

The findings of the study provide valuable insight for hoteliers in developing a green strategy that will foster frugality amongst Muslim hotel guests. It will also help them develop better strategies for the frugal segment, especially for the Muslim community.

The study is amongst the pioneers in investigating frugality in the tourism industry. It is also the first to introduce price consciousness as a moderator of the relationship between the green attitude and frugality. Furthermore, its examination of frugality amongst Muslim hotel guests is a new contribution to the literature.

The environmental impact of excessive use of natural resources such as energy and water in the tourism industry has increased significantly. Thus, it is crucial to investigate the notion of frugality in this industry. Particularly, this study aims to examine the effect of green marketing strategies (eco-labelling and environmental advertising) and hotel guests’ green attitude towards frugality in the context of the Malaysian hotel industry. Furthermore, the mediating effect of green attitude is also examined.

Stimulus-organism-response theory was used to develop the research framework. The data were collected via a self-administered survey questionnaire, which yielded 150 complete and usable responses. A partial least square-structural equation modelling approach was used to validate the proposed model.

The results of this study revealed that environmental advertising and eco-labelling, directly and indirectly, affect frugality. Moreover, the link between green attitude and frugality also was supported. Furthermore, data supported the mediating effect of green attitude in the relationship between green marketing strategies and frugality.

The findings from this study can benefit hoteliers who are targeting frugal and environmentally conscious consumers. Moreover, the hoteliers will be able to understand the drivers of frugality in the tourism industry. It can assist them to formulate better marketing strategies in attracting and retaining frugal consumers.

The findings from this study offer a number of important social implications for society, the local government and the city and tourism council. Particularly, understanding the strategies towards frugality can pave the way towards the formation of a “less consumption” community. Moreover, it will serve as the guideline for designing the green and sustainability campaign for the nation.

This study is among the pioneers to investigate the issue pertaining to frugality in the tourism industry context. This study examines new linkages such as the indirect effect of green marketing strategies towards frugality. Moreover, the mediating effect of green attitude in the relationship between green marketing strategies (eco-labelling and environmental advertising) and frugality is comparatively a new link.

The majority of the synthetic dyes have been found to be non-biodegradable, toxic and carcinogenic. As a result, there has been a growing trend toward the use of natural dyes as alternates to synthetic dyes. This shift calls for more research to come up with more sources of natural dyes to satisfy their increasing demand. Euclea divinorum plant has been used traditionally as a source of dye, however, its textile dyeing properties have not been studied. This study aims to determine the textile dyeing properties of E. divinorum extract.

Optimization of dyeing conditions of Euclea divinorum natural dye extract on the cotton fabric was done using response surface methodology (RSM). The combined effects of examined dyeing conditions on the relative color strength (K/S) were studied using a central composite experimental design. Analysis of variance (ANOVA) was used to determine the significance of the statistical model generated for the study. Mordanting effects were measured using standard ISO wash, rub and lightfastness tests.

The optimum dyeing conditions were found to be 68 min, pH 3.3 and 82°C with color strength 0.609. Temperature and pH showed some interaction effects during the dyeing experiments. The predicted optimum K/S value was validated experimentally using the optimum conditions and was found to be in agreement with the experimental values. All the metallic mordants used enhanced the color strength and provided a variety of brown shades, therefore, a suitable alternative for the toxic synthetic dyes.

Optimization of dyeing conditions of Euclea divinorum dye on cotton using RSM and mordanting at optimal conditions has not been done elsewhere.
