The purpose of this study is to develop a novel general mathematical model to find the optimal product mix of commercial graphite products, which has a complex production process with alternative sub-processes in the graphite mining production process.

The network optimization was adopted to model the complex graphite mining production process through the optimal allocation of raw graphite, byproducts, and saleable products with comparable sub-processes, which has different processing capacities and costs. The model was tested on a selected graphite manufacturing company, and the optimal graphite product mix was determined through the selection of the optimal production process. In addition, sensitivity and scenario analyses were carried out to accommodate uncertainties and to facilitate further managerial decisions.

The selected graphite mining company mines approximately 400 metric tons of raw graphite per month to produce ten types of graphite products. According to the optimum solution obtained, the company should produce only six graphite products to maximize its total profit. In addition, the study demonstrated how to reveal optimum managerial decisions based on optimum solutions.

This study has made a significant contribution to the graphite manufacturing industry by modeling the complex graphite mining production process with a network optimization technique that has yet to be addressed at this level of detail. The sensitivity and scenario analyses support for further managerial decisions.

Predatory publishing is a growing and global issue infecting all scientific domains. Predatory publishers create counterfeit, not (properly) peer-reviewed journals to exploit the open access (OA) model in which the author pays. The plethora of predatory marketing journals along with the sophisticated deceptive practices of their publishers may create total confusion. One of the many highly likely risks of that bewilderment is when peer-reviewed, prestigious marketing journals cite these pseudo-marketing journals. This phenomenon is called citation contamination. This study aims to investigate the extent of citation contamination in the peer-reviewed marketing literature.

Using Google Scholar as a citation gathering tool, this study investigates references to four predatory marketing journals in 68 peer-reviewed marketing journals listed in the 2018 version of the Academic Journal Guide by the Chartered Association of Business Schools (CABSs).

Results indicate that 59 of the 68 CABS-ranked peer-reviewed marketing journals were, up to late January 2021, contaminated by at least one of the four sampled predatory journals. Together, these four pseudo-journals received (at least) 605 citations. Findings from nonparametric statistical procedures show that citation contamination occurred irrespective of the age of a journal or its 2019 Journal Impact Factor (JIF). They also point out that citation contamination happened independently from the fact that a journal is recognized by Clarivate Analytics or not.

This study investigated citations to only four predatory marketing journals in only 68 CABS-listed peer-reviewed marketing journals.

These findings should sound an alarm to the entire marketing community (including academics and practitioners). To counteract citation contamination, recommendations are provided for researchers, practitioners, journal editors and academic and professional associations.

This study is the first to offer a systematic assessment of references to predatory journals in the peer-reviewed marketing literature.

The purpose of this paper is to investigate the link between Islamic finance for entrepreneurship activities and economic growth in Malaysia within the model of endogenous growth.

This study applied a parametric analysis represented by vector autoregression (VAR) Granger causality and a non-parametric analysis represented in the bootstrapped quantile regression to examine the effect of Islamic finance for entrepreneurship activities on economic growth within the model of endogenous growth. This paper used a sample of all Islamic banks working in Malaysia covering a period from 2014 first quarter until 2019 third quarter (2014Q1–2019Q3).

The findings demonstrated that Islamic finance for entrepreneurship activities are promoting economic growth in Malaysia which indicates that Islamic finance is a vital contributor to economic growth through financing entrepreneurial domains small and medium-sized enterprises.

The analysis in this paper would fill the literature gap by investigating the link between Islamic finance for entrepreneurship activities and economic growth within the model of endogenous growth in Malaysia as this study serves as a guide for the researchers and decision-makers to the necessity of merging Islamic finance as a major player in the economy to finance the entrepreneurial domain which contributes to economic growth.

This study is the first that investigates the relationship between Islamic finance for entrepreneurship activities and economic growth empirically using the causality and quantile regression within a new theoretical approach over the model of endogenous growth to provide a proven valuable experiment from Malaysia concerning Islamic finance for the entrepreneurial domain which promotes economic growth.

This study aims to enhance our understanding of employee emotional competence (EEC) in the context of service failure and recovery. Accordingly, the present study investigates the relationship between perceived EEC and customer emotional attachment (CEA) through the mediating role of service recovery satisfaction (RES). Furthermore, the study examines the moderating impact of service failure severity (SFS) on the relationship between perceived EEC and RES.

A self-administered online survey was carried out to collect data. Using a convenience sampling technique, 195 US consumers were recruited from Prolific Academic. To test the hypotheses, this study employed partial least squares structural equation modeling (PLS-SEM).

According to the analysis, perceived EEC impacts CEA directly and indirectly via RES. Additionally, the study finds that consumers reported feeling more emotionally connected to the restaurant when they were satisfied with service recovery. Finally, the study identified that the connection between perceived EEC and RES increases with service failure severity.

This study emphasizes enhancing EEC through organization-wide training to increase customer satisfaction and emotional attachment to the service organization. Furthermore, it underscores the need for comprehensive employee training to categorize service failure severity and formulate appropriate recovery strategies.

The authors believe this is the first RES study to examine perceived EEC’s effect on CEA. By combining the affect infusion and cognitive appraisal theories to examine recovery satisfaction, this study contributes to the existing body of research on service recovery by shedding light on the relationship between perceived EEC and CEA. Furthermore, the study offers preliminary findings indicating an increase in the impact of perceived EEC on RES during high failure severity (SFS).

The purpose of this paper is to investigate the relationship between board gender equality and environmental, social and governance (ESG) performance in the European banking sector. The study examines whether and how the presence of women on the board of directors (BoD) influences ESG dimensions.

The authors analyzed a sample of 72 European Union banks for the period 2015–2021 and developed an econometric model applying unbalanced panel data regression with firm fixed effects and controls per year. To test the research hypotheses, the authors considered gender equality in terms of female participation on the BoD and measured ESG dimensions by using the ESG score provided by Refinitiv.

The findings suggest a significant positive relationship between the number of women on BoD and the ESG performance of European banks only up to a certain threshold of female directors (at least three women). The study also explores how the proportion of women on BoD influences the individual ESG pillars. The results show that the percentage of female directors has a positive and statistically significant impact on the social dimension of the ESG framework.

The investigation is highly relevant to investors considering ESG issues in their decision-making process. The overall findings support policymakers and regulators on how to improve ESG performance through the design and the application of corporate governance (CG) mechanisms. From a managerial perspective, the study suggests that managers and CEOs should focus their efforts on establishing the right gender combination of directors on bank BoDs.

This paper offers an in-depth examination of the CG practices of banks, and it attempts to bridge the gap in prior literature on the determinants of ESG issues in the European banking industry. To the best of the authors’ knowledge, this study is the first that investigates the relationship between the representation of women on BoDs and the ESG dimensions measured by the Refinitiv Eikon score. The use of critical mass theory adds a fresh perspective to the literature on ESG in Europe since the influence of board gender diversity on ESG performance of the European banks is still unaccounted for. This study addresses this pressing research issue drawing on resource dependence, agency and legitimacy theories.

With the growing need for employees to be innovative, public-sector organizations are investing in employee training. This study aims to examine the effects of a combined Lean Six Sigma and innovation training, using action learning, on public-sector employees’ creative role identity and innovative work behavior.

The authors studied a public service agency in Singapore in which a five-day Lean Innovation Training was implemented, using a combination of Lean Six Sigma and Creative Problem-Solving tools, with a simulation on day one and subsequent team-based project coaching, spread over six months. The authors administered pre- and postintervention surveys among all the employees, and initiated group interviews and observations before, during and after the intervention.

Creative role identity and innovative work behavior had significantly improved six months after the intervention, enabled through senior management’s transformational leadership. The training induced managers to role-model innovative work behaviors while cocreating, with their employees, a renewal of their agency’s core processes. The three completed improvement projects contributed to an innovative work culture and reduced service turnaround time.

Starting with a role-playing simulation on the first day, during which leaders and followers swapped roles, the action-learning type training taught all the organizational members to use various Lean Six Sigma and Creative Problem-Solving tools. This nimble Lean Innovation Training, and subsequent team-based project coaching, exemplifies how advancing the staff’s creative role identity can have a positive impact.

Based on the agency and resource dependence theories, this study aims to investigate whether nomination committee (NC) characteristics could serve as key attributes for reducing environmental, social and governance (ESG) disputes and whether NC composition affects the appointment of ESG-friendly directors to the board.

This study focuses on a sample of 30 global systemically important banks from 2015 to 2021. The authors estimate panel data models with fixed effects, clustering heteroskedastic standard errors at the bank level to account for the serial correlation of the dependent variables for each bank.

Banks’ exposure to ESG controversies can be reduced when NC members have specific skills, in particular when at least one member of this committee also belongs to the sustainability committee and is a foreign director. Moreover, banks’ ESG disputes decrease when the NC members are younger, while the share of independent NC members has a negative impact. Finally, a positive influence of NC composition and its members’ features as well as the appointment of ESG-friendly directors on the board is found.

The findings are particularly useful during periods such as the current one, when there is growing attention to both banks’ corporate governance, the subcommittees’ role and functioning and social and environmental issues. This study shows that the NC is important in reducing the likelihood of banks incurring ESG disputes and in appointing more ESG-friendly directors. NC effective functioning and its members’ qualities serve as a key attribute for fulfilling objective assessment and improving board effectiveness.

The study aims to examine the impact of corporate governance in terms of certain board characteristics on the level of universities’ voluntary sustainability disclosure.

A content analysis based on a comprehensive disclosure index – that also accounts for the impact that COVID-19 exerted on the social dimension of university activities – is performed on a sample of Italian public universities’ websites for the year 2020. An ordinary least squares regression model is estimated to test the association between universities’ board characteristics, namely, board size, board independence and board gender diversity (including the presence of a female rector), and online sustainability disclosure.

This study provides evidence that websites represent a valid tool used by universities to highlight their social performance and demonstrate their commitment to dealing with the pandemic’s social and economic disruption by supporting their stakeholders. Board gender diversity and female Rector’s presence are crucial factors that positively impact voluntary sustainability disclosure levels.

Policymakers and regulators can benefit from the study’s findings. Using the results of this study, they may reflect on the need to regulate sustainability reporting in universities. In addition, findings may offer policymakers inspiration for regulating the presence of women on university boards.

This study offers novel contributions to existing literature analysing the university’s voluntary sustainability disclosure practices through alternative communication tools such as websites. Moreover, it provides novel insight into the role of the board gender diversity in university sustainability disclosure practices.
