Abstract
Purpose
This study aims to prepare some disperse dyes based on pyrazole derivatives and fully evaluate their use as azo-disperse dyes linked with pyrazolo[1,5-a] pyrimidine. This study aims to prepare dye polyester fabric at different conditions (pH and time) at a depth of 4% using a high-temperature pressure process in water.
Design/methodology/approach
The disperse dyes were created by dissolving enaminone and pyrazole derivatives in glacial acetic acid and fusing sodium acetate at reflux for 6 h. The chemical structure of the produced dye was studied using elemental analysis, Fourier-transform infrared spectroscopy, 1H NMR and 13C NMR spectroscopic analytical methods. The dyeing of Dispersed dyes 14–16 on polyester under diverse conditions was comprehensively investigated in this work.
Findings
The prepared Organic dyes 14–16 were found to be highly functional and suitable for this type of dyeing technique. High color strength is possessed by the materials dyed with Disperse dyes 14–16. Even in low alkaline conditions, these dyes exhibited a strong affinity for polyester fabric, changing just little in response to pH changes. The hue of the dyed polyester samples varied from beige to reddish brown and yellowish brown because of the coupler moieties.
Originality/value
This study is important because it offers novel dyes that may be used to dye polyethylene terephthalate fibers that exhibit remarkable brightness and levelness. It also offers a viable solution for creating a variety of colors in polyester fabrics.

Abstract
Purpose
This study aims to assess consumers’ beliefs in three Middle Eastern Arab countries regarding attitudinal and behavioural responses towards permission-based direct email marketing (hereafter DEM) and the moderating role of gender in the hypothesised path model.
Design/methodology/approach
Structural equation modelling was used to test the hypothesised path model by using data collected from 829 respondents.
Findings
The findings show that attitude was found to fully mediate the relationship between beliefs and behavioural responses towards permission-based DEM. Gender moderates the relationship between beliefs and attitudes and responses to permission-based DEM. Notably, female respondents were found to react more actively when exposed to permission-based DEM.
Research limitations/implications
Further qualitative research is needed to learn more about how and why individuals develop behavioural intentions in certain ways towards opt-in DEM. In addition, neuropsychology approaches such as eye-tracking are endorsed for future research to gain more insights and conquer biases associated with self-reporting procedures in countries where such technologies are deemed as legal and ethical to be used with human subjects.
Practical implications
Advertisers promoting products and services in the Middle Eastern Arab context should take further steps to enhance the quality of information (including cultural sensitiveness) and the perceived entertainment value that could be delivered to consumers through permission-based DEM, especially for female internet users. Additionally, this study highly recommends the double opt-in approach to permission-based DEM.
Originality/value
To the best of the authors’ knowledge, this is the first attempt to address the gender role as a moderator of the path depicting the effectiveness of permission-based DEM approach in the Middle East (Arab counties) from beliefs to behavioural responses via attitudes.

Abstract
Purpose
The Metaverse is rapidly reshaping the understanding of tourism, yet the public perception of this new domain remains largely uncharted empirically. This paper aims to build on the technology acceptance model (TAM) and diffusion of innovations theory (DIT) to fill this gap, offering crucial insights that could inform scholars and practitioners in both the tourism and technology sectors.
Design/methodology/approach
Using a big-data approach, the authors applied machine learning to scrape comments made by social media users on recent popular posts or videos related to tourism in the Metaverse from three prominent social media platforms. The cleaning process narrowed down 15,461 comments to 2,650, which were then analysed using thematic, emotion and sentiment analysis techniques.
Findings
The thematic analysis revealed that virtual tourism evokes a complex range of public beliefs. While many express awe and excitement toward its immersive capabilities, others remain sceptical about authenticity compared to physical travel. Additional themes show people draw comparisons to real-world tourism, discuss technology’s role and note educational value and novelty. However, some comments raise concerns about potential societal harms, exploitation and mental health impacts. Sentiment analysis found over half of the comments positive, though some were negative. Emotion analysis showed contentment, happiness and excitement as most frequent, though sadness, worry and loneliness also featured. Overall, perceptions of Metaverse tourism encompass enthusiasm yet substantial ambivalence.
Originality/value
To the best of the authors’ knowledge, this study is one of the first to comprehensively analyse public discussions on Metaverse tourism. It takes TAM and Rogers’s DIT a step further and provides fresh insights into how these theories can be employed in the emerging field of Metaverse tourism. The themes revealed new conceptual insights into multidimensional factors shaping public beliefs about Metaverse tourism and thus informing scholarly research on virtual interaction and technology acceptance regarding Metaverse tourism. In addition, the results can help tourism providers, platforms and marketers address salient public beliefs and sentiments/attitudes in developing marketing offerings, experiences and communications. Over time, this analysis methodology can be used to track the evolving public perceptions of Metaverse tourism.

Abstract
Purpose
The purpose of this research is to shed light on the chain of psychological and behavioral effects that precipitates from a materialistic state of mind. Specifically, this study examines the psychological impact of materialism on younger consumers and in turn, their compulsive buying (CB) habits. This study also proposes possible interventions that may enhance consumer resistance to materialism and buying impulses and, ultimately, protect consumers’ mental and financial well-being.
Design/methodology/approach
An online survey was assembled in Qualtrics using reputable scales from extant marketing and psychology literature. The survey was completed by 193 young adults. Structural equation modeling was used to evaluate the proposed model of psychological drivers of CB.
Findings
The results suggest that young, materialistic consumers are at high risk of developing depression. Moreover, obsessive-compulsive (OC) tendencies and impaired self-esteem (SE) resulting from this depression may facilitate and fuel CB addiction. Despite no evidence for a direct link between depression and CB, the results indicate that this particular relationship is fully mediated by OC behavior and low SE.
Social implications
The discussion provides a detailed list of various behavioral modifications to help reduce consumer susceptibility to materialistic values and CB addiction.
Originality/value
This study contributes to consumer research by proposing an alternative conceptualization of the traditionally direct relationship assumed between materialism and CB in the literature. The facilitating roles of depression and its psychological byproducts (i.e. impaired SE and OC disorder) are examined as precursors of CB. Implications and suggestions for consumers battling CB addiction are provided.

Abstract
Purpose
This study aims to explore blockchain potential for digital marketing (BlkChn-Mk-KAP) by developing and validating a measurement model for assessing the constructs of knowledge, attitude and practice (KAP) related to blockchain technology in digital marketing.
Design/methodology/approach
A four-study process was used. The first study reviewed the literature to develop a pool of possible measurement items. Using exploratory factor analysis and reliability assessments, Study 2 (n = 162) investigated the dimensionality of the items developed in Study 1. The factorial structure from Study 2 was validated in Study 3 (n = 204), and the measurement model invariance was assessed using covariance-based structural equation modelling (CB-SEM). Finally, in Study 4 (n = 203), the predictive validity of the BlkChn-Mk-KAP was tested using a CB-SEM approach, testing its constructs correlations with the perceived usefulness of blockchain for digital marketing.
Findings
The findings indicate that the BlkChn-Mk-KAP measurement model comprises three-dimensional multi-item scales: knowledge, attitude and practice.
Research limitations/implications
This study introduces a promising BlkChn-Mk-KAP model to examine blockchain’s role in digital marketing. The authors acknowledge the sampling limitation in this research. To enhance the generalisability of the findings, future research should expand to different groups, including generation, gender and age. In addition, further exploration of the explicit links between blockchain knowledge, attitudes and subsequent digital marketing performance is warranted.
Practical implications
Educating employees about blockchain technology’s unique features can shape favourable attitudes and stimulate the utilisation of blockchain-enabled technologies in digital marketing practice. BlkChn-Mk-KAP can offer a reliable and valid instrument to benchmark marketers’ KAP of blockchain-powered digital marketing as they implement blockchain technology to gain a competitive advantage.
Social implications
This study helps to adopt sustainable practices ensuring the wellbeing of the key stakeholders.
Originality/value
This research introduces the first validated conceptualisation and measurement model, BlkChn-Mk-KAP, to evaluate blockchain KAPs among digital marketing professionals.

Abstract
Purpose
The purpose of this study is to determine the nature of archaeological papyrus damage and monitoring the mechanics of damage caused by black inks to the chemical properties of ancient papyrus.
Design/methodology/approach
This study the papyrus surface with a digital microscopy “USB,” examination and analyzing by “Scanning Electron Microscope,” characterization of black ink used in writing the ancient papyrus using “Scanning Electron Microscopy” with (EDX). Detection of changes in the chemical bonds of ancient papyrus samples by “Fourier transform infrared” FTIR.
Findings
The result confirmed that SEM examination showed the organization of the parenchyma cells that make up papyrus tissue. Characteristic waveform appears, it indicates the ancient Egyptian manufacturer’s use of the (Strips Method) in the process of manufacturing the archaeological papyrus. Also, the appearance of (Over Lapping) stacking of papyrus slides. EDX analysis showed that the black ink used to write the papyrus was (Carbon Ink). High oxygen content in the papyrus sample analysis indicates deterioration of the cellulose fibers. FTIR spectrum showed that Arabic gum is the bonding material for carbon ink particles, it also showed that archaeological papyrus suffers from hydrolysis due to exposure of papyrus fibers to high moisture content or direct water, resulting in smudge, bleeding and fading of carbon ink on the archaeological papyrus support.
Originality/value
The study is archaeological papyrus with black ink scripts from the excavation of the Qasr I brim.

Abstract
Purpose
This paper focusses on demonstrating the role of social media engagement and considering emotional intelligence (hereafter EI) as a critical concept to successful employment, mainly when individuals fail to reach the desired employment despite “meeting” the role requirements.
Design/methodology/approach
The authors adopted a qualitative approach through semi-structured in-depth interviews of some randomly selected university students in the UK, young adults aged 19–32. The participants were selected based on different demographics to provide a broader and less biased representation of young adults in the UK.
Findings
This research suggests that recruitment organisations should introduce the latest requirements and trends of employers to ensure that the expectations of employers and potential candidates are aligned to improve the employment rate in young adults.
Originality/value
This research extends the literature regarding EI in social media engagement and successful employment. It also brings new perspectives on successful employment in young adults by demonstrating the role of social media engagement and EI traits leading to a conceptual framework exploring successful employment based on the role of social media engagement and EI.

Abstract
Purpose
This study aims to explore the intermediate role of self-differentiation in anger management and neurotic perfectionism for a sample of high achievers at some public universities in Egypt and Saudi Arabia. This increases the chances of these students obtaining their rights.
Design/methodology/approach
The researcher used the microcopy of Drake, Murdock, Marszalek and [(the Differentiation of Self Inventory—Short Form (DSI-SF)] scale, differentiation of self child-adolescent perfectionism scale and Davidson and Munro (2000) scale of neurotic perfectionism in addition to the anger management scale of the current study. The researcher used the appropriate statistical methods and the descriptive design to find the results.
Findings
The results showed that there is no statistically significant difference among male and female students in the positive anger management while three was a statistically significant difference among them in the negative anger management favoring male students. Further, there were no statistically significant differences among the study sample according to the country (Egypt and Saudi Arabia) in anger management (positive and negative). Moreover, there was a correlation matrix between the study variables as shown in the study; The statistical analysis was conducted to identify the suggested constructive model and variables of the study, anger management (positive-negative) as an independent variable, self-differentiation as an intermediate variable and neurotic perfectionism as a dependent variable among high achievers, This explains the necessity of preparing the environment for these students to become more healthy, through which they can enjoy all their rights as a category of special education, where most of the focus is on the handicapped groups from special education more than the high achievers’ students.
Originality/value
The study recommended that higher education courses should focus on anger management skills and the development of self-differentiation and the positive part of perfectionism. Also, the current study provided the educators of higher education with some suggestions to promote it and develop high achievers, which may lead to positive mental and physical health for high achievers and raising awareness of society and obtaining their rights in education and life.

Abstract
Purpose
This article critically synthesizes the literature on sustainable fashion, the movement behind it and plausible fashion adoption theories. Then, to build on those studies, developing a new theory about adopting sustainable fashion – mainly among millennials and Generation Z who are behind forwarding and adopting this fashion trend – is sought after.
Design/methodology/approach
This is a theory-synthesized conceptual article that presents a literature-informed new theoretical structure pronouncing sustainable fashion adoption and its rise as a new luxury trend. That included explicating and unraveling the conceptual foundations and construction elements that different viewpoints use to articulate the trend under investigation and the searches for a common basis to construct a new and improved conceptual framework.
Findings
This study introduces the triple-trickle theory that incorporates the role of media and technology to organize and understand the diffusion of sustainable fashion and identify paths for future trickle-effects on fashion research.
Research limitations/implications
Even though this has the benefit of offering a vast array of views and evidence that offers an adequate problem inspection, further studies providing empirical evidence are needed to establish the external validity of the theory derived from this research.
Practical implications
This theory can be applied to develop targeted practices to understand the diffusion and adoption of sustainable fashion and further practitioners’ understanding of product positioning, target marketing, marketing strategy and luxury opportunities in general.
Originality/value
Though interest in sustainable fashion has increased among consumers, no theory or model exists to explain its adoption. Therefore, the triple-trickle theory is proposed and aimed to be a more relevant framework to offer a theoretical premise for future empirical investigations of sustainable fashion adoption.
