Abstract

Purpose

The purpose of this paper is to identify and analyse the fermentative properties of a strain of indigenous Wickerhamomyces anomalus (W. anomalus) from Rosa roxburghii Tratt (R. roxburghii).

Design/methodology/approach

Morphological and molecular methods were used to determine the species of the selected strain W. anomalus C11. The physiological tolerances to glucose, ethanol, citric acid and sulphur dioxide (SO2) were further assessed by checking the growth of cells, and the oenological performances were proved to measure the related fermentative properties of R. roxburghii wines.

Findings

The W. anomalus C11 strain could be grown faster than commercial S. cerevisiae X16 in its logarithmic growth period and had preferable tolerances to glucose, ethanol, citric acid and SO2. Moreover, this strain of native R. roxburghii yeast W. anomalus C11 produced less sulphuretted hydrogen and had a higher β-glucosidase activity. Furthermore, W. anomalus C11 could reduce the volatile acids, reduce the sourness and enhance volatile aroma richness and complexity of R. roxburghii wines including types of aroma and content thereof. Taken together, the R. roxburghii native yeast W. anomalus C11 may have potential for use in R. roxburghii winemaking.

Originality/value

(1) The fermentative properties of a strain of indigenous W. anomalus (named as C11) from R. roxburghii was evaluated. (2) The strain of W. anomalus C11 had preferable tolerances to glucose, ethanol, citric acid and SO2. (3) This strain of native R. roxburghii yeast W. anomalus C11 produced less sulphuretted hydrogen and had a higher ß-glucosidase activity. (4) W. anomalus C11 could reduce the volatile acids, reduce the sourness and enhance volatile aroma richness and complexity of R. roxburghii wines including types of aroma and content thereof.

Abstract

Purpose

Increased ethanol accumulation during ethanol fermentation generates stress in yeast cells, which finally reduces the fermentation performance and efficiency. Trehalose, a potential stress protectant, has been reported to regulate the response of yeast to diverse environmental stresses. This study aimed to explore how exogenous trehalose application affects the survival, transcriptome and antioxidant enzymes of Wickerhamomyces anomalus grown under ethanol stress conditions.

Design/methodology/approach

Exogenous trehalose was applied to the growth condition of W. anomalus, and optical densitometric method was used to detect contents of intracellular trehalose and MDA and activities of CAT and SOD. The survival was evaluated using spot analysis. Differentially expressed genes (DEGs) were identified through transcriptomics analysis.

Findings

The results showed that ethanol stress induced the accumulation of intracellular trehalose, with further exogenous trehalose application improving the survival and alleviating oxidative stress in ethanol-stressed W. anomalus. Transcriptomic results showed that trehalose has pleiotropic regulating effects on ethanol-stressed W. anomalus since most DEGs annotated to energy metabolism, amino acid metabolism, translation, folding, sorting and transport were affected post trehalose addition. Therefore, it is found that trehalose protected W. anomalus against ethanol stress, and these findings provide interesting insights into the mechanistic role of trehalose in improving ethanol stress tolerance of W. anomalus.

Originality/value

(1) Protective effect of exogenous trehalose addition on the survival of ethanol-stressed W. anomalus was proved. (2) Exogenous trehalose addition could partly alleviate oxidative stress induced by ethanol stress and affect transcriptome in W. anomalus.

Abstract

Purpose

This study aims to investigate the hierarchical relationship between industry-specific attributes of supply chain (SC) strategies and information technology (IT) to improve the performance of firms in textile industry in Pakistan.

Design/methodology/approach

This study presents a mix of enablers through literature review and experts’ opinions. Next, the driving and dependence powers of enablers were identified, using the interpretive structural modeling (ISM) approach.

Findings

The ISM model suggests eight levels, with customer satisfaction at the top of the model. Process automation and TQM are placed at second and third level, respectively, whereas flexible sourcing and flexible capacity are positioned at fourth level. The key enablers of IT have high driving power, hence positioned at the bottom of ISM model.

Originality/value

This study has value for firms in garment manufacturing and exporting industry to invest into IT and sustainable SC design for competitive performance. The theoretical and managerial implications are provided.

Abstract

Purpose

The purpose of this paper is to analyze the effects of data-driven capabilities on supply chain integration (SCI) and competitive performance of firms in the food and beverages (F & B) industry in Pakistan.

Design/methodology/approach

The authors adopt the structural equation modeling approach to test the proposed hypotheses using AMOS 23. Survey data were collected from 240 firms in the F & B industry in Pakistan.

Findings

The results revealed that SCI (i.e. internal integration (II) and external integration (EI)) significantly mediates the effect of data-driven capabilities (i.e. flexible information technology resources and data assimilation) on a firm’s competitive performance. In addition to the direct effects, II also has an indirect effect on competitive performance through EI.

Practical implications

The study has several implications for managers in the context of big data application in food supply chain management (FSCM) in a developing country context. The study posits that firms can achieve excellence in performance by governing data-driven supply chain operations. The study also has implications for distributors and importers in the F & B industry. The cloud-based sharing of data can improve the operational performance of channel members while reducing their overall cost of operations. In practice, food franchises largely get the advantage of shared resources of their suppliers in managing orders, payments, inventory and after-sales services.

Originality/value

The study is novel and deepens the understanding about the use of big data in FSCM keeping in view the industry trends and stakeholder’s priorities in a developing country context.

Abstract

Purpose

This research seeks to examine the mitigating effect of religiosity on the relationship between abusive supervision and unethical behavior in employees, with moral disengagement serving as a mediating factor. Drawing on social cognitive theory, the study proposes an overarching moderated mediation framework to analyze this complex dynamic.

Design/methodology/approach

The testing of the model was based on hierarchical data obtained from 70 work units in services sector. Within this framework, 70 supervisors evaluated the unethical conduct of employees, while 700 employees assessed the abusive supervision they experienced and reported on their own moral disengagement and religiosity. For the analysis of both the measurement and the hypothesized models, multilevel modeling techniques in the Mplus software were utilized.

Findings

The study's findings indicate a direct positive link between abusive supervision and employees' unethical behavior, with moral disengagement mediating this relationship. Furthermore, the research discovered that abusive supervision leads to unethical behavior in employees through moral disengagement only in instances where their religiosity is low.

Originality/value

This research delves deeper by elucidating the role of moral disengagement in the dynamic between abusive supervision and unethical behavior. Diverging from prior research, this study uniquely highlights the moderating role of religiosity, showing its potential to weaken the impact of abusive supervision on unethical behavior in employees through moral disengagement.

Abstract

Purpose

Humility as an important factor for leaders was identified by Collins (2001) and his colleagues in an extensive research project about the leadership qualities of the leaders of companies that transitioned from “good” to “great.” This paper is an empirical study of six factors closely associated with humility and leadership and the purpose of this paper is to identify how Chinese business students and Chinese employees perceive the importance of six factors associated with humility as enlightened leadership.

Design/methodology/approach

This paper summarizes recent research about humility and leadership and suggests seven hypotheses about the importance of six factors associated with humility as enlightened leadership.

Findings

This study confirms that Chinese respondents affirmed the value of all six factors and identified the statistical significance of three of the factors studied.

Research limitations/implications

A limitation of this study is that it is exploratory in nature and contained many factors that made conducting factor analysis indeterminable. The practical implications of this study are that it provides confirming information about understanding the value system and priorities of Chinese employees and future workers when multi-national companies interact with Chinese partners.

Originality/value

This study provides valuable information about the six factors associated with humility as enlightened leadership. This study is the first of its kind that empirically tests Chinese attitudes associated with humility and leadership.

Abstract

Purpose

Using the theoretical lens of appraisal theory, this research aims to investigate the interrelationship between employees' organizational justice perceptions and counterproductive work behaviours (CWBs) through the mediation of negative emotions.

Design/methodology/approach

To this end, a sample comprised of 207 banking sector employees of Pakistan was utilized to test hypothesized relationships. The collected data were analyzed through the partial least structural equation modelling technique.

Findings

Results show that counterwork behaviours are influenced by distributive and procedural justice perceptions. The mediating effects of negative emotions were also statistically significant between procedural, interpersonal and informational justice perceptions and counterwork behaviours. No gender differences were found between distributive, interpersonal and informational justice perceptions and counterwork behaviours. However, the authors found that procedural justice perceptions of female employees are strongly related to CWBs as compared to male employees.

Originality/value

This research contributes to the existing organizational behaviour literature by empirically testing the hypothesized relationships using the theoretical lens of appraisal theory with advanced quantitative data analysis techniques.
