Abstract
Purpose
Snack industry is one of the fastest growing food sectors globally, and people are nowadays conscious about intake of healthy snacks on regular basis. There is enormous variety of ready-to-snacks available in the market. Brown rice though highly nutritious in comparison to polished rice is consumed meagerly by masses. Each raw material/ingredient used in extrusion cooking requires specific control of processing variables to meet acceptable product characteristics and consumer demands, which in turn necessitates the need to optimize the conditions for development of brown-rice-based snacks. The aim of this study was to optimize the extrusion cooking conditions for development of brown-rice-based extrudates.
Design/methodology/approach
Extrusion conditions were optimized through design expert using central composite rotatable design (CCRD) experimental design. The effect of feed moisture (10–22%), screw speed (215–385 rpm) and barrel temperature (95–160 °C) on specific mechanical energy (SME), bulk density (BD), water absorption index (WAI), water solubility index (WSI), expansion ratio (ER), breaking strength (BS) and instrumental color (L*, a*, b*) was evaluated.
Findings
All the system and product responses were significantly (p < 0.01) affected by independent variables. Regression models obtained were highly significant with high coefficient of determination (R2 = 0.992). The optimum extrusion conditions obtained by numerical optimization for development of snacks were moisture content of 12%, screw speed of 350 rpm and temperature of 133 °C. The vitamin B1 content of brown-rice-based snacks was 0.45 mg/100 (50% of RDA) whereas no vitamin B1 was detected in white-rice-based snacks used as control.
Practical implications
The developed snacks contain 0.45 mg/100 g of vitamin B1. If a person on an average consumes 150 g of snacks in a day, 50% of RDA (1.2 mg/day) for vitamin B1 can be sufficed. Therefore, developed snacks can prove to be a viable vehicle to reduce the vitamin B1 deficiency burden among the target population. Large-scale production and consumption of such type of snacks could improve the nutritional status of vitamin B1 deficient people. Furthermore, it can also provide a good opportunity for snack industry to develop nutritious snacks through utilization of brown rice.
Originality/value
Brown rice flour contains nutrients such as iron, calcium, zinc, sodium and vitamin B1 in appreciable portions and was thus explored for development of nutritious snacks. Moreover, developed snacks recorded an overall acceptability of 4.70 out of 5, which depicts it is acceptable for mass production and consumption.

Abstract
Purpose
Drawing on the dual process model of ideology and prejudice, the purpose of this paper is to examine whether, how and when a supervisor's Machiavellianism leads to subordinates' perceptions of abusive supervision. In doing so, the authors also explore the mediating role of the supervisor's competitive world views and the moderating role of subordinates' performance on this relationship.
Design/methodology/approach
The theoretical model was tested using three sources of data from supervisors, their subordinates and the organization. Hierarchical linear model analysis was run on supervisor and subordinate dyadic data for testing whether subordinates' performance moderated the mediated relationships or not.
Findings
The results suggest that the supervisors' competitive worldviews explain the positive link between their Machiavellianism and subordinates' perceptions of abusive supervision. The results highlight that the mediation effect of supervisors' competitive worldviews on the link between their Machiavellianism and their subordinates' perceptions of abusive supervision is more pronounced when subordinates' performance is low than when it is high.
Research limitations/implications
This research contributes to the authors’ knowledge of the link between supervisors' Machiavellianism and abusive supervision, and how the toxic influence of their Machiavellianism is mediated by supervisors' competitive worldviews.
Originality/value
The study contributes to the literature on abusive supervision and personality by studying the role of personality as an antecedent of abusive supervision. Further, this study used subordinates' performance as a contextual variable for understanding abusive supervision.

Abstract
Purpose
This study aims to investigate the impact of enterprise social media (ESM) usage on employee agility through communication quality and visibility. Theory of communication visibility is used to explore the moderating role of ESM-related strain in the relationship among communication quality, visibility and employee agility.
Design/methodology/approach
The research model is analyzed using data from 240 Chinese employees of different companies. The proposed hypotheses are tested using structural equation modeling, hierarchical regression and mediation analysis.
Findings
Findings suggest that ESM usage is positively related to communication quality and visibility. Communication visibility mediates the relationship between ESM usage and employee agility. ESM-related strain reduces the relationship between communication visibility and employee agility. However, ESM-related strain has an insignificant moderating effect on the relationship between communication quality and employee agility.
Originality/value
The present study examines how employee agility is associated with ESM usage in the workplace. The mediating effects of communication quality and visibility are explored using a theoretical foundation. This study provides empirical evidence on how the impact of ESM on employee agility is transmitted through communication visibility. Lastly, the current study quantifies the advantages of ESM for organizations and may motivate managers to confidently deploy ESM in the workplace.

This paper aims to investigate the impact of Hofstede’s cultural factors on customers’ attitudes toward Facebook advertising through the moderating role of gender.
Abstract
Purpose
This paper aims to investigate the impact of Hofstede’s cultural factors on customers’ attitudes toward Facebook advertising through the moderating role of gender.
Design/methodology/approach
This study used the quantitative method and the research tool was a questionnaire, comprising 38 items, which was distributed in Jordan. A total of 404 correctly completed questionnaires were returned. In total, 187 of the respondents were women and 217 men. Multiple regression analysis was conducted to test the research hypotheses.
Findings
The results of the current study revealed that differences in each dimension have varied impacts on consumers’ attitudes. From the perspective of individualism, it appears that individualistic customers tend to make their own decisions and are less susceptible to influence from others. Also, uncertainty avoidance can negatively impact attitudes toward Facebook advertising due to a lack of trust. In addition, this study investigates differences in attitudes toward Facebook advertising based on gender. The null hypothesis test is statistically rejected and the alternate hypothesis test is statistically accepted for gender role as the moderating variable.
Originality/value
This is the first study that examines the impact of Hofstede’s cultural factors on customers’ attitudes toward Facebook advertising through the moderating role of gender in Jordan. Also, the study clarifies the importance of culture and gender differences as important factors affecting marketing strategy. Moreover, the study’s result can add more value to international companies to understand culture differences among customers with an international scope.

Abstract
Purpose
The findings of this study have lightened the focal research areas in maintenance planning and scheduling. These also served as effective guidelines for future studies in this area. This research, therefore, contributes in fulfilling the gap by carrying out an SLR of contemporary research studies in the area of models for maintenance planning and scheduling. At present, SLR rooted in BA has not been carried focusing on a survey over models for maintenance planning and scheduling. SLR uses advanced scientific methodologies from BA tools to unveil thematic structures.
Design/methodology/approach
We have systematically reviewed over 1,021 peer-reviewed journal articles. Advanced contemporary tools from Bibliometric Analysis (BA) are used to perform a Systematic Literature Review (SLR). First, exploratory analysis is presented, highlighting the influential authors, sources and region amongst other key indices. Second, the large bibliographical data is visualized using co-citation network analyses, and research clusters (themes) are identified. The co-citation network is extended into a dynamic co-citation network and unveils the evolution of the research clusters. Last, cluster-based content analysis and historiographical analysis is carried out to predict the prospect of future research studies.
Findings
BA tools first outlined an exploratory analysis that noted influential authors, production countries, top-cited papers and frequent keywords. Later, the bibliometric data of over 1,021 documents is visualized using co-citation network analyses. Later, a dynamic co-citation analysis identified the evolution of research clusters over time. A historiographical direct citation analysis also unveils potential research directions. We have clearly observed that there are two main streams of maintenance planning and scheduling applications. The first has focused on joint maintenance and operations on machines. The second focused on integrated production and maintenance models in an echelon setting for unrealizable production facilities.
Originality/value
There are many literature review-based research studies that have contributed to maintenance scheduling research surveys. However, most studies have adopted traditional approaches, which often fall short in handling large bibliometric data and therefore suffer from selection biases from the authors. As a result, in this area, the existing reviews could be non-comprehensive. This study bridges the research gap by conducting an SLR of maintenance models, which to the best of our knowledge, has not been carried out before this study.

Abstract
Purpose
Drawing on social learning and social cognitive theories, this study aims to examine a multi-level moderated mediation model that tests the mediating effect of moral disengagement (MD: Level 1) between perceived organisational politics (POP: Level 1) and employee knowledge hiding from coworkers (EKHC: Level 1). The authors further propose that supervisor knowledge hiding from employees (SKHE: Level 2) moderates this mediation effect.
Design/methodology/approach
The authors obtained multi-sourced, multi-timed and multi-level data regarding 294 employees, working under 80 supervisors, from multiple organisations operating in Pakistan. The authors analysed these data using multi-level structural equation modelling via Mplus.
Findings
The results show that employee MD significantly mediates the direct relationship between POP and EKHC. The mediation effect is further positively moderated by SKHE, which amplifies the mediation effect.
Originality/value
To the best of the authors’ knowledge, this is the first empirical study that examines both EKHC and SKHE together in a single research model and provides a thorough understanding of why, how and when POP leads to EKHC.

Abstract
Purpose
This study aims to examine the negative effects of excessive product packaging (EPP), greenwashing and green confusion on green brand equity (GBE). Furthermore, the moderating role of brand credibility in mitigating the negative effects of green marketing was investigated.
Design/methodology/approach
A within-subject experiment was conducted to evaluate excessive versus minimal product packaging to test the proposed hypotheses. Data analysis was performed with SmartPLS 3.3.3, which analyzed data from 206 consumers.
Findings
The results showed that EPP positively predicts greenwashing and green confusion. However, greenwashing has a negative impact on GBE. Brand credibility was also discovered to moderate the negative relationship between greenwashing and GBE, thereby reducing the negative effect of greenwashing.
Research limitations/implications
The findings imply that marketing managers should understand the consumers’ concerns for the environment, making product and brand strategies that promote environmental protection and sustainability.
Originality/value
This study contributes to the green marketing literature by empirically validating the positive impacts of EPP on greenwashing and green confusion, as well as the negative influence of greenwashing on GBE. Furthermore, it reveals how brand credibility can reduce the harmful effects of greenwashing on GBE.
Objetivo

Abstract
Purpose
The purpose of this paper is to determine the need of Islamic Accounting Standards – a review of the literature – for Islamic financial institutions (IFIs).
Design/methodology/approach
The basis of the paper was stakeholder theory to analyse the need of accounting standards and to design the conceptual framework as evidenced from Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI). The evidence reviewed suggests the need for Islamic accounting standards to fill the gap in accounting practice among Islamic financial institutions.
Findings
The AAOIFI accounting standards serve as a guideline that may reflect the unique characteristics of IFIs and become a useful tool to meet the various needs of IFIs. Currently, one of the major challenges facing IFIs lies in the preparation of the financial statements under different accounting standards and which may lead to problems of comparability, reliability and compliance level measurement. This has resulted in a heated debate among scholars which has hitherto translated to the evolving existing literature surrounding the interpretation of the level of compliance with the Islamic accounting standards. The paper concludes with various recommendations for future research, the most important of which is the need for future studies on how AAOIFI accounting standards can be made mandatory in all Muslim countries.
Originality/value
This paper contributes towards a better understanding and acceptability of the need of Islamic Accounting Standards.

Abstract
Purpose
This paper aims to examine the effect of capital structure on Islamic banks’ (IBs) performance to provide guidance to finance managers for raising capital funds. As newcomers to the markets, IBs are facing a trade-off. They can either use high capital ratios which increase the soundness and safety of the bank and lower the required return by investors, or depend on deposits and Islamic bonds which are considered cheaper sources of funds due to their tax rebate. An IB’s management must carefully decide the appropriate mix of debt and equity, i.e. capital structure, to maximize the value of the bank.
Design/methodology/approach
Using a sample of 85 IBs covering banking systems in 19 countries, the study uses a two-stage least squares method to examine the performance determinants of IBs to control the reverse causality from performance to capital structure.
Findings
After control of the macroeconomic environment, financial market structure and taxation, results indicate that IBs’ performance (profitability) responds positively to an increase in equity (capital ratio). The result is consistent with the signaling theory which predicts that banks expected to have better performance credibly transmit this information through higher capital. Optimal capital structure results of the IBs found a non-monotonic U-shaped relationship between the capital-asset ratio and profitability, supporting the efficiency risk and franchise value hypotheses.
Research limitations/implications
Due to limitations for market data, the study uses book accounting ratios. Future research where market data are available could use performance measures, such as Tobin’s Q in performance determinants models.
Practical implications
The non-monotonic relationship found between IBs’ return on equity and capital ratios suggests that equity issuances for IBs’ with low capital ratios (lower than the turning point of 37.41 per cent) are expensive and have a negative effect on their profitability. On the other hand, managers of well-capitalized IBs (banks with capital ratios beyond 37.41 per cent) are advised to rely on equity when faced by a decision to raise capital, as the capital ratio starts to affect their profitability positively.
Originality/value
Islamic banking literature has been silent on IBs’ capital structure and its relevance; this study will try to fill in the existent gap.

Abstract
Purpose
This study aims to examine process improvement strategy (PIS) (proxied by remote work, workforce training, and technological innovation), and employee productivity amid the COVID-19 pandemic among bank employees.
Design/methodology/approach
The study employed cross-sectional and descriptive design by applying multistage sampling techniques using convenience sampling to select the study organization and stratified and simple random sampling to select 900 respondents for the study. Data were collected by using validated measures of the study variables designed into a questionnaire. Pearson’s correlation and simple regression analysis were employed to establish relationships and causal effects among variables respectively.
Findings
Results showed significant relationships between the PIS (work-from-home, workplace training, and technological innovation) and the outcome variable (employee productivity); and predictive capabilities between the PIS and the outcome variables (employee productivity). The study revealed that remote work accounted for the highest variability (R2 = 0.775) in employee productivity, followed by workplace training (R2 = 0.499), and finally investment in technological innovation (R2 = 0.486)] and as such PIS fosters employee productivity and may, therefore, be applied when faced with a similar pandemic in the future.
Originality/value
The study was recognized for its significance in examining how PIS supports enhancing employee productivity in banks and, by extension, other organizations during a pandemic. The research has proven to be crucial in providing insights into bank management in emerging economies and other organizations worldwide that have previously gone unnoticed during a pandemic. It has aided in the extension of existing literature on PIS and employee productivity by carefully developing a framework, thus covering practical knowledge gaps.
