Abstract
Illicium griffithii (local name - Lissi) belongs to the family Illiaceae. It produces yellow colored natural dye from its stem and leaves, which has been used to dye textiles for the first time here. In the present study, innovative dyeing with Illicium griffithii has been shown to give good dyeing results. Pre-mordanting with 1-2% metal mordants viz. alum, copper sulphate, ferrous sulphate, potassium dichromate, stannous chloride and stannic chloride, and using 5% (o.w.f.) of plant aqueous solution of the extract, is found to be satisfactory and shows very good fastness properties for cotton, wool and silk fabrics. The innovative solvent extraction of the dry stem-leaves of Illicium griffithii is an easy process; the solvent is removed/recovered and the aqueous extract is used for dyeing. The CIELab and color strength (K/S) of the dyed fabrics are also evaluated. The superiority of solvent extraction over conventional extraction has been established through this study.

Abstract
Purpose
The purpose of this paper is to evaluate the efficiency of ultrasonication on new natural dye obtained from leaves and stem extracts of Daphne papyraceae using metal mordant for good cotton, silk and wool dyeing prospects. It also proposes to effect the characterisation of the colorant.
Design/methodology/approach
For effective natural dyeing with leaves and stem extracts of D. papyraceae, both conventional and sonication methods for cotton, silk and wool dyeing were carried out using metal mordants. The purpose of using sonication was for betterment of dye uptake, improved dye adherence and good wash and light fastnesses. Results show marked improvement by the chosen dyeing method. Simultaneously, chemical characterisation of the colorant was carried out by first column chromatographic separation of the crude extract, followed by spectral analysis of the isolated products.
Findings
The superiority of sonicator dyeing over conventional dyeing in terms of enhanced resource productivity and, as a result, reduced wastes makes it the established best available technique in the natural dyeing industry. This fact has been examined for several natural dyes. Use of sonicator shows marked enhancement for cotton‐, silk‐ and wool‐dyed fabrics. Typical bath liquor to fabric ratio for conventional dyeing varies from 20:1 to 15:1 and for sonicator dyeing from only 12:1 to 10:1, thereby reducing specific water and energy consumption by 30 and 50 per cent, respectively. The cycle time for dyeing was also reduced by 50 per cent and this would benefit the dyeing process with more tonnage of fabric per unit time and with lower waste generation. This would also result in improved capacity utilization leading to enhanced productivity levels in the dyeing houses.
Research limitations/implications
Although metal mordanting with copper sulphate and potassium dichromate is not ecofriendly, only 2 per cent of these metal salts has been used to prepare different shades with leaves and stem extracts of D. papyraceae for cotton, silk and wool fabrics.
Practical implications
The method developed for natural dyeing of cotton, silk and wool fabrics using sonication in conjunction with metal mordanting has shown marked improvement. The chemical composition of the crude extract shows the presence of flavonoids and other specific natural pigments.
Originality/value
The method developed for natural dyeing of cotton, silk and wool fabrics using stem and leaves extracts of D. papyraceae under sonication in conjunction with metal mordanting has shown marked improvement in terms of dye adherence and fastness properties and can thus be recommended for industrial application. This is a new source of natural dye.

Abstract
Purpose
Using the person-organization (P-O) fit perspective, the present study explores the interlinkages between workplace spirituality (WPS) and organizational citizenship behavior (OCB). It further attempts to understand the mediating effects of psychological ownership and innovative work behavior (IWB) for the association.
Design/methodology/approach
Data was collected in three waves from 283 frontline hotel employees in the Delhi NCR region of India. Partial least square (PLS-structural equation modeling) was used to test the hypothesized model.
Findings
A significant association was found between WPS and OCB. Psychological ownership and IWB had a significant serial mediation effect on WPS and OCB relationship.
Practical implications
The involvement of spirituality in the workplace is one of the significant factors contributing to positive organizational performance from the perspective of perishable services. Hence, understanding and implementing best practices to encourage WPS and strengthening psychological ownership for favorable behavioral outcomes must be one of the significant priorities for human resource managers in the hospitality industry.
Originality/value
WPS is an under-explored area in the hospitality industry. The present study will be novel and critical in bridging the research gap wherein psychological ownership and IWBs mediate the relationship between WPS and OCB in the hospitality sector. Furthermore, the present study notably contributes to using person organizational fit theory for the hypothesized relationships between study variables for the hospitality sector employees in India.

Abstract
Purpose
The study proposes to determine the impending challenges to lean integration with Industry 4.0 (I4.0) in manufacturing that aims at achieving desired operational performance. Integrating lean and Industry 4.0 as the two industrial approaches is synergetic in providing operational benefits such as increasing flexibility, improving productivity, reducing cost, reducing delivery time, improving quality and value stream mapping (VSM). There is an urgent need to understand the integrated potential of OPEX strategies like lean manufacturing and also to determine the challenges for manufacturing SMEs and further suggest a strategic roadmap for the future.
Design/methodology/approach
The current work has used a combined approach on interpretative structural modeling (ISM) and fuzzy Matrice d'impacts croisés multiplication appliquée á un classment (MICMAC) approach to structure the multiple level analysis for the implementation challenges to integrate OPEX strategies with Industry 4.0.
Findings
The research has found that the indulgence of various implementation issues like lack of standardization, lack of vision and lack of trained support, all are the major challenges that inhibit the integration of OPEX strategies with I4.0 technologies in manufacturing.
Research limitations/implications
The research has investigated the internal factors acting as a roadblock to lean and Industry 4.0 adoption. Further studies may consider external factors to lean and Industry 4.0 implementation. Also, further research may consider other operational excellence approaches and extend further to relevant sectors.
Practical implications
This study provides the analysis of barriers that is useful for the managers to take strategic actions for implementing OPEX strategies with I4.0 in smart manufacturing.
Originality/value
The research determines the adoption challenges towards the integrated framework. This is the first study to explore challenges in integrating OPEX strategies with I4.0 technologies in manufacturing SMEs.

Abstract
Purpose
Using the extant literature review, this paper aims to explore the relationship between gender, entrepreneurial education (EE) and entrepreneurial intention (EI) in the Indian context, which the authors believe is a novel approach to this research stream. The authors also use career preparedness as a control variable to examine this relationship.
Design/methodology/approach
Data were collected from 368 undergraduate students across four Indian universities (one exclusively for female students) through a standard structured questionnaire. Additionally, rather than examining, EI has been treated as a monolithic construct; however, the authors conceptualize it as comprising three different dimensions that include grand vision and risk-taking ability; opportunity exploitation; and ability to persevere. An additional analysis was conducted for the students who reported higher scores for “being well prepared for their careers” through their institutes’ academic programs and communities of entrepreneurs. The authors also interviewed some entrepreneurship instructors, who confirmed the present findings through their observations.
Findings
The findings indicate that, essentially, there is a positive relationship between EE and EI. The authors find that male students scored higher for the first two dimensions of EI but not the third. Additionally, the authors used career preparedness as a control variable for additional analysis. The authors observed that students with higher “career preparedness” reported a positive relationship between EE and EI, independent of gender, for all three dimensions of EI. Thus, it may be assumed that if a community of entrepreneurs needs to be developed in India, a focus on career preparedness is critical.
Research limitations/implications
First, given that the present survey reflected a single moment in linking EE to EI (which may be considered a limitation of the study), future researchers might focus on a longitudinal approach. Second, all the respondents are attending urban universities (and, as such, very likely belong to the upper middle class of Indian society). The financial divide between urban and rural India is well known; as such, the results might be different if the sample was drawn from rural and poor India.
Originality/value
The salience/value of this study lies in the conceptualization of EI comprising three sub-constructs to understand the impact of formal EE (with three sub-constructs) on EI. The focus on career preparedness for a female student is a new direction of inquiry with respect to entrepreneurial intention.

Abstract
Purpose
The present paper intends to study the relationship between Machiavellianism and effectiveness. It investigates the parallel mediating effects of self-esteem and ethical leadership on Machiavellianism and leader effectiveness.
Design/methodology/approach
The study was administered to 260 managers from the banking sector. Statistical tools, like descriptive statistics, Pearson product moment correlation, reliability analysis, validity analysis and parallel-mediated regression analysis, were used to analyze the data. Drawing from the conservation of resource (COR) theory, a parallel mediation model was empirically tested.
Findings
The study found a negative association between Machiavellianism and leader effectiveness, and the parallel mediating impact of self-esteem and ethical leadership reduced the impact of Machiavellianism on leader effectiveness.
Practical implications
The work suggests that the banking sector leaders can adapt ethical behaviors to create positive leader–member relations contributing to increased organizational efficiency and productivity.
Originality/value
The unique contribution of the study includes determining the mediating roles of self-esteem and ethical leadership, especially in the Indian context. Despite the availability of past studies on the constructs, the studies on the parallel mediating relationship between Machiavellianism and effectiveness was limited.

Abstract
Purpose
This study aims to analyze the stock market reaction of the small and medium sectors in the Southeast Asian countries (SEACs), including China, to the Russia–Ukraine war.
Design/methodology/approach
This study uses the event study methodology to quantify the magnitude and direction of the impact of the Russia–Ukraine war on the performance of small and medium indices of SEACs. Assuming market efficiency, this study uses the market model to capture abnormal returns on the event date and across the event window.
Findings
The Russia–Ukraine war adversely affected most of the sample countries, with a prolonged impact over the 50-day post-event window. In most cases, the study has failed to establish statistical significance for the results. One major reason for the low impact is the proactive role of the governments of the SEACs in mitigating the war’s impact on their respective economies by providing subsidies, exercising price controls and stockpiling.
Originality/value
To the best of the authors’ knowledge, this study is the first to analyze the impact of the Russia–Ukraine war on the small and medium sectors of SEACs, including China. It highlights the importance of geographic proximity and the proportion of bilateral trade in understanding how war and geopolitical tensions affect the stock market performance in other countries in the current global scenario. In addition, this study uses a range of parametric and nonparametric tests that adjust for the cross-country dependence and event-induced volatility to substantiate the statistical significance of the results and this supports the robustness of the results.
