Everyone is extremely concerned about environmental protection and health safety due to the rise in living standards. Plant-derived natural dyes have garnered much industrial attention in food, pharmaceutical, textile, cosmetics, etc. owing to their health and environmental benefits. The present study aims to focus on the elimination of the use of synthetic dyes and provides brief information about natural dyes, their sources, extraction procedures with characterization and various advantages and disadvantages.

In producing natural colors, extraction and purification are essential steps. Various conventional methods used till date have a low yield, as these consume a lot of solvent volume, time, labor and energy or may destroy the coloring behavior of the actual molecules. The establishment of proper characterization and certification protocols for natural dyes would improve the yielding of natural dyes and benefit both producers and users.

However, scientists have found modern extraction methods to obtain maximum color yield. They are also modifying the fabric surface to appraise its uptake behavior of color. Various extraction techniques such as solvent, aqueous, enzymatic and fermentation and extraction with microwave or ultrasonic energy, supercritical fluid extraction and alkaline or acid extraction are currently available for these natural dyes and are summarized in the present review article.

If natural dye availability can be increased by the different extraction measures and the cost of purified dyes can be brought down with a proper certification mechanism, there is a wide scope for the adoption of these dyes by small-scale dyeing units.

This study aims to explore the use of gamification elements by micro and small e-tailers to enhance customer loyalty. Additionally, this research seeks to identify the most promising gamification elements that can be utilised for this purpose.

The authors adopt a qualitative approach to examine the impact of gamification on online customer loyalty to micro and small e-tailers. Data were gathered using a combination of two types of expert interviews. Semi-structured interviews were held with micro and small e-tailers while large e-tailers served as the control group. Structured interviews based on multi-criteria decision analysis (MCDA) models were conducted to determine the most promising gamification elements.

The content analysis reveals that gamification has significant potential for fostering customer loyalty and offering various other benefits. However, small e-tailers often refrain from implementing gamification solutions due to the resource requirements in terms of finances, time, information technology and human capital. By assigning weights as an essential step in MCDA models, the authors determined that badges, medals, quests, avatars and competitions are the most promising gamification options for small e-tailers’ efforts to enhance customer loyalty.

The study makes a unique contribution to the understanding of the usefulness of gamification in augmenting customer loyalty and identifying essential gamification elements for micro and small e-tailers.

Grounded in the conservation of resources theory, this study proposes the mechanisms and conditions under which customer mistreatment affects employee proactive behavior. This study focuses on insomnia as a mediating mechanism and resilience as a boundary condition for the indirect effect of customer mistreatment on employee proactive behavior via insomnia.

We conducted a single survey in two phases, with a time lag of three weeks, among 302 frontline South Korean employees. The data collected from these two points were then analyzed using hierarchical regression analysis and the PROCESS macro.

The findings demonstrated that there was a significant negative relationship between customer mistreatment and employee proactive behavior, and this relationship was mediated by insomnia. Furthermore, the results revealed that resilience moderates both the effect of customer mistreatment on insomnia and the indirect effect of customer mistreatment on employee proactive behavior through insomnia.

This research primarily focuses on Korean frontline workers, potentially limiting cultural generalizability. The reliance on self-reported data may introduce common method bias. Future studies should diversify participant demographics and utilize multi-source feedback to validate findings. Grounded in the Conservation of Resource Theory, this study underscores the neglected linkage between customer mistreatment and proactive behavior, especially in frontline employees. We introduce insomnia as a pivotal mediator, deepening our understanding of why mistreatment dampens proactivity. Additionally, we spotlight the role of resilience, revealing its buffering effect against mistreatment’s adverse outcomes.

Organizations should be aware of the detrimental effects of customer mistreatment on frontline employees, as it can hamper proactive behavior, primarily through the exacerbation of insomnia. Implementing resilience-training programs can be a proactive step, offering frontline staff tools to buffer against such negative outcomes. Managers are encouraged to recognize and address instances of customer mistreatment and prioritize employee well-being, which in turn can foster a more proactive and resilient workforce, enhancing organizational performance and customer satisfaction.

This study underscores the broader societal challenge of customer mistreatment in the service sector, highlighting its ripple effects on employee well-being and proactive behavior. It sheds light on the importance of fostering respectful interactions in public and private spaces, emphasizing mutual respect between customers and service providers. Recognizing the adverse impacts of mistreatment can prompt societal discourse on workplace ethics and encourage organizations to advocate for their employees' rights. Ultimately, nurturing a culture that condemns customer mistreatment can lead to healthier work environments, benefitting both employees and society at large.

This study presents a novel approach by investigating the impact of customer mistreatment on employee proactive behavior, considering insomnia as a mediator, a perspective that has received limited attention in existing literature. Additionally, it introduces the concept of resilience as a moderator, offering fresh insights into how individual resilience levels can affect the relationship between customer mistreatment and proactive behavior. The research goes beyond traditional analyses of workplace dynamics to explore the broader implications of these interactions on personal well-being and sleep patterns. Through the application of a moderated-mediation framework, this study enhances understanding of complex organizational behavior dynamics, particularly in the service sector, and provides valuable implications for both theoretical understanding and practical application.

Drawing upon the social network theory (SNT), the aim of this study is to examine the impact of value co-creation (VCC) on retailer loyalty (RL) and omni-channel shopping frequency (OCF) from the consumer perspective.

Grounded on SNT, the research focuses on VCC in omni-channel retailing. A paper-based questionnaire was used to examine the role of VCC on OCF and RL, and hypotheses were tested using structural equation modeling (SEM).

The findings supported the impact of VCC on RL, and in turn, the impact of RL on OCF. However, the results of the analysis reveal that RL has no mediator role between VCC and OCF.

The study shows the increasing role of VCC on RL, and the important role of RL on OCF. The findings reveal that RL has a significant role for VCC and OCF separately but does not have a mediator role between VCC and OCF. Moreover, the study extends the knowledge on VCC in omni-channel retailing.

The new research model, which was hypothesized from SNT, was validated. In the omni-channel retailing context, the study revealed the consumer perspective on VCC, and also the linkages between VCC, RL and OCF.

This research is an empirical study that addresses whether knowledge resources impact on, or do not impact on, innovation development and if this impact is mediated by dynamic capabilities in the medical tourism sector in Mashhad city, Iran.

A quantitative research methodology was applied and questionnaires were used for data collection in this study. A total of 108 questionnaires were collected of which 102 questionnaires were valid. Data were analyzed using structural equation modelling technique.

Empirical evidence obtained from the study reveals that the dynamic capability of learning plays a significant role in transforming knowledge resources into innovation in the medical tourism sector. The mediating role of coordinating capability in the relationship between explicit and tacit knowledge and innovation is considerable and it influences human capital, as well. Sensing capability also exhibits some degree of a mediating role; however, integrating capability is not influential and its role in transforming explicit knowledge to innovation is rejected.

Most studies on innovation in medical tourism focused on market and its typology, and neglected the role of knowledge resources and dynamic capabilities. The current study bridges this gap and thus contributes to the scientific literature.

Grounded on brand equity theory and theory of patronage behavior, this study aims to investigate the moderating effect of consumer involvement and shopping situations in the relationship between consumer-based retailer equity (CBRE) and retail patronage behavior.

The data is collected through a self-administered survey of 338 shoppers in the three biggest shopping centers in Pakistan. Moreover, the data is analyzed through multi-nominal (multiple) regression and interactions analysis.

Results revealed a significant effect of CBRE on patronage behavior and confirmed shopping purpose as a boundary condition in the CBRE-retail patronage behavior relationship. However, the study surprisingly reported that this relationship is not moderated by consumers’ involvement.

Considering our focus on CBRE-based retail patronage behavior, the authors contribute to extant marketing/retailing literature that also yields ample openings for further research. The study offers valuable implications for retailers, especially for evaluating consumers’ behaviors.

This study assists retail-brand managers in best comprehending the CBRE-based patronage behavior paves the way for managers to increase retail patronage behavior.

Regardless of the growing comprehension of consumer-based brand equity and patronage behavior in marketing, more needs to be acknowledged about the relationship between CBRE/retail patronage behavior and related variables, as thus examined in this research.

Basado en la teoría del valor de marca y la teoría del comportamiento de patrocinio, este estudio investiga el efecto moderador de la implicación del consumidor y las situaciones de compra en la relación entre el valor del minorista basado en el consumidor (CBRE) y el comportamiento de patrocinio minorista.

Los datos se recogen mediante una encuesta autoadministrada a 338 compradores en los tres mayores centros comerciales de Pakistán. Además, los datos se analizan mediante regresión multinominal (múltiple) y análisis de interacciones.

Los resultados revelaron un efecto significativo del CBRE en el comportamiento de patrocinio y confirmaron el propósito de compra como una condición límite en la relación CBRE-comportamiento de patrocinio minorista. Sin embargo, el estudio informó sorprendentemente de que esta relación no está moderada por la implicación de los consumidores.

Teniendo en cuenta que nos centramos en el comportamiento de patrocinio minorista basado en el CBRE, contribuimos a la literatura existente sobre marketing/minoristas que también ofrece amplias posibilidades para futuras investigaciones. El estudio ofrece valiosas implicaciones para los minoristas, especialmente para evaluar los comportamientos de los consumidores.

El presente estudio ayuda a los gestores de marcas minoristas a comprender mejor el comportamiento de patrocinio basado en la CBRE y allana el camino para que los gestores aumenten el comportamiento de patrocinio minorista.

A pesar de la creciente comprensión de la equidad de marca basada en el consumidor y el comportamiento de patrocinio en marketing, es necesario reconocer más sobre la relación entre el comportamiento de patrocinio basado en la CBRE y las variables relacionadas, como se examinó en esta investigación.

本研究以品牌资产理论和顾客行为理论为基础, 探讨了消费者参与和购物情境在基于消费者的零售商资产（CBRE）与零售顾客行为之间关系中的调节作用。

数据是通过对巴基斯坦三大购物中心的 338 名购物者进行自填式调查收集的。此外, 还通过多项式（多元）回归和交互分析对数据进行了分析。

结果表明, CBRE 对顾客光顾行为有显著影响, 并证实购物目的是 CBRE 与零售顾客光顾行为关系的边界条件。然而, 令人惊讶的是, 研究报告称这种关系并没有受到消费者参与度的调节。

考虑到我们对基于 CBRE 的零售顾客行为的关注, 我们为现有的市场营销/零售文献做出了贡献, 同时也为进一步研究提供了广阔的空间。本研究为零售商提供了宝贵的启示, 尤其是在评估消费者行为方面。

本研究有助于零售品牌管理者更好地理解基于 CBRE 的顾客行为, 为管理者提高零售顾客行为铺平了道路。

尽管市场营销中对基于消费者的品牌资产和顾客行为的理解不断加深, 但仍需进一步认识 CBRE/零售顾客行为与相关变量之间的关系, 正如本研究中所探讨的那样。
