The purpose of this paper is to empirically examine the effect of royal family members on firm performance of publicly listed companies in Saudi Arabia.

Using 491 firm-year observations of non-financial publicly listed firms in Saudi Arabia’s stock market between 2009 and 2013, the study employs, besides others, the advanced econometric technique GMM-system estimator. This allows the dynamic nature and control of the endogeneity problem to be accounted for in corporate governance and firm performance.

The main result is that the attendance of royal family members at board meetings negatively influences firm performance but does not have an influence on firm value. The results also show that firms with many independent royal family members on the board of directors have better firm performance and firm value. In addition, firms with a high number of royal family members presenting on the board have better firm performance.

This study offers guidance to assist the further investigation of the SA Royal Family’s BoD membership either in SA or in other monarchy countries. It is interesting to compare these results in order to further understand the different effects that the Royal Family’s BoD membership have in such countries. This study’s results suggest that independent members of SA’s Royal Family on the BoD have some influence on firm performance in both the short and long term. Thus, policymakers should encourage the members of SA’s Royal Family to become more involved in firms’ BoDs.

This study offers guidance for further investigation of royal family members in the region or in other monarchy countries. It will be interesting to compare these results. The study suggests that royal family members on the board have a partial influence on firm performance, especially the independent ones. Thus, the policymakers should encourage more involvement of independent royal family members on the board.

Foreign and minority investors, who invest in SA’s publicly listed firms, should note that when independent members of SA’s Royal Family are on the BoD their investment will benefit from the reduced risks and uncertainty.

To the best of the author’s knowledge, this is the first study undertaken to investigate empirically the influence a royal family’s presence on the board of directors has on firm performance. This study is based on both theories, namely the agency theory and resource dependence theory.

Research has shown that information and communication technologies (ICT) are crucial for economic growth. The purpose of this paper is to develop a framework that would depict and examine the nature of the relationship between ICT use and organizational performance in the Lebanese market, taking into consideration the impact that innovation and corporate entrepreneurship may have on this relationship.

To investigate the proposed model a survey targeting employees, and managers who adopted ICT applications in SMEs located in Lebanon was conducted.

The results indicate that ICT and innovation are strategic resources. However, their contribution to sustainable competitive advantage vitally depends on the implicitness and entrepreneurial behaviors of those involved. It is through this capability that ICT and ICT-based innovations could make a difference in organization’s performance – both present and future.

First, the respondents were selected using the convenience sampling technique. Second, the data were collected through self-report questionnaires. Finally, the use of perceptual data related to performance may have a bias effect on the study results.

At the practical level, the study results have repercussions for managers, technology suppliers, and innovation adopters and managers, as this may contribute to better understanding of the factors that could influence the adoption, management, and use of ICT resources for enhancing the competitiveness level of the firm.

The results of this study have implications for ICT adoption in Lebanese SMEs. More importantly, they suggest a framework which depicts the relationship between ICT and the organization’s innovation level on one hand, and a company’s performance on the other, taking entrepreneurship as a mediator in this relationship.

The purpose of this paper is to investigate the performance of Islamic banks in developing countries from 2007 to 2010 which includes the period of the financial crisis by empirically examining the way in which the macroeconomy affected Islamic banking performance (IBP) in developing countries. The empirical examination involves two approaches of measuring performance: Sharia-based and conventional-based performance measurement.

For this paper, the authors have utilized a Data Stream/Bank Scope database and data from the Bank Negara Malaysia (Malaysian Central Bank) to collect a panel set of annual financial information for Islamic banking from the year 2007-2010. The initial sample covers 34 Islamic banks from developing countries that are listed on the International Islamic Service Board. Furthermore, the authors adopted only those listed Islamic banks to tackle the data availability issue. The authors’ final sample comprised 136 observations with complete data as the numbers of Islamic banks in developing countries are low in comparison to their conventional peers. The financial crisis dummy follows America’s commonly used National Bureau of Economic Research timeline for the financial crisis. The authors also used the method of a generalized least square (GLS) method of pooled panel data analysis regression model. The rationale for employing the GLS technique was made on the basis of the ability of GLS to give less weight to the error term that is closely clustered around the mean, to improve the goodness of fit and to remove autocorrelation compared with normal, random, and fixed effect models.

The authors of this paper found that the macroeconomic factors reflected in gross domestic product, gross domestic product growth, and inflation rate have a significant positive relationship with the return on assets. In addition, a significant negative relationship was found between the financial dummy and IBP in developing countries. On the other hand, it failed to find evidence of a relationship between the macroeconomic factors and performance including the legal system and the financial crisis dummy, when the performance is reflected by the Zakat ratio. The result embedded that the financial crisis had an impact on the performance of Islamic banks in developing countries when viewed from the conventional banking perspective. The financial crisis played a role in reducing the profitability of Islamic banks which is consistent with a previous study by Hasan and Dridi (2011). However, in the view of Sharia, the financial crisis did not have any effect on IBP; even the macro factors did not have any effect on the level of performance.

There are possible explanations for these contradictory coefficient signs. First, the contradictory signs of the coefficient for the same independent variable that was regressed with different dependent variables show that researchers would need to take caution in using the right indicators when measuring IBP. Conventional indicators bring different results in comparison to Islamic indicators (Badreldin, 2009; Mudiarasan. Kuppusamy, 2010; Zahra and Pearce, 1989). Second, Richard et al. (2009), having reviewed performance measurement-related publications in five of the leading management journals (722 articles between 2005 and 2007), suggested that the past studies reveal a multidimensional conceptualization of organizational performance with limited effectiveness of commonly accepted measurement practices. Accordingly, these studies call for more theoretically grounded research and debate for establishing which measures are appropriate in a given research context. Today, there is a general consensus that the old financial measures are still valid and relevant (Yip et al., 2009). However, these need to be balanced with more contemporary, intangible, and externally oriented measures. It has been argued that various researchers working in their own disciplines using functional performance measures (such as market share in marketing, schedule adherence in operations and so on) ought to link their discipline to focused performance measures of overall organizational performance.

Islamic banking has unique characteristics in comparison to conventional banking and this paper examines the differences between the two and also investigates the resilience of Islamic banks during a period of economic turbulence. Furthermore, due to these unique characteristics, a comparison cannot be made by using the conventional performance measures alone. In addition, amid the in-depth studies examining the resilience of Islamic banks during periods of economic crises, there are instances of theoretical disagreement in the extant empirical literature examining finance and economics. In that regard, the majority of the existing literature is either based on advanced markets or countries where the majority of the population practices the faith of Islam, and little is known about the performance of Islamic banking from the pooled emerging markets; particularly in developing countries.

Introducing Zakat as a performance measurement in Islamic banking context relating it to macroeconomic factors enhances the thinking of new research in Islamic theory about bank performance.

This study aims to examine the influence of the three dimensions of travel agents’ manager competencies – ability, motivation and opportunity seeking – on knowledge transfer and travel agents’ performance. In addition, the study investigates how employee’s absorptive capacity moderates the effects of managers’ competencies on knowledge received by the employees and moderates the effects of knowledge received by the employees on travel agents’ performance.

A positivist research philosophy was adopted with a quantitative approach, in which quantitative data were gathered based on questionnaires to tackle different stages of the study. To test the hypotheses, a self-administrated face-to-face survey of about 42 questions, launched on November 7, 2016, was used to compile response from top and medium management Category A travel agents operating in Egypt.

Based on a sample of 577 travel agents’ frontline employees, the results showed that the three dimensions of travel agents’ competencies have a positive effect on knowledge received by the employee. Findings further indicated that knowledge received by employee mediates the link between these three competencies and travel agents’ performance. The link between the competencies and knowledge received by the employee was found to be positively moderated by employee absorptive capacity. Moreover, these findings suggested that the relationship between knowledge received and travel agents’ performance is stronger when employees’ absorptive capacity is greater.

This study is bound by certain limitations that also provide fertile grounds for further research. First, the study examined how an employee’s absorptive capacity moderates the effects of managers’ competencies on knowledge received by the employees and moderates the effects of knowledge received by the employees on travel agents’ performance. However, innovation as a dependent variable can be investigated. Second, one limitation is that the study is restricted to Category A travel agents only in Greater Cairo. Third, examining the antecedents of ability, motivation and opportunity seeking to transfer knowledge is also important.

It is important for travel agents, owners, managers and employees to acknowledge absorptive capacity as a critical component for organizations to sustain, grow and compete. Travel agents can also take steps to develop their employees’ absorptive capacity. Doing so would further enhance the success of knowledge, employees and travel agents’ performance. Also, travel agents’ top management has to ensure their employees’ absorbing knowledge, identifying and recognizing external knowledge, processing and understanding it, combining it with existing knowledge and applying the new knowledge to commercial ends. Hence, the development of absorptive capacity contributes to a travel agent’s achievement of competitive advantage.

This study contributes to the literature by expanding the extant literature on knowledge transfer and absorptive capacity by investigating the influence of travel agents’ manager competencies – ability, motivation and opportunity seeking – for knowledge transfer in the Egyptian context. In addition, it investigates the direct effects of the three dimensions of travel agents’ manager competencies – ability, motivation and opportunity seeking – for knowledge transfer. Finally, the paper investigates how employee’s absorptive capacity moderates the effects of managers’ competencies on knowledge received by the employees and moderates the effects of knowledge received by the employees on travel agents’ performance

This study aims to propose an unsupervised learning model to evaluate the credibility of disaster-related Twitter data and present a performance comparison with commonly used supervised machine learning models.

First historical tweets on two recent hurricane events are collected via Twitter API. Then a credibility scoring system is implemented in which the tweet features are analyzed to give a credibility score and credibility label to the tweet. After that, supervised machine learning classification is implemented using various classification algorithms and their performances are compared.

The proposed unsupervised learning model could enhance the emergency response by providing a fast way to determine the credibility of disaster-related tweets. Additionally, the comparison of the supervised classification models reveals that the Random Forest classifier performs significantly better than the SVM and Logistic Regression classifiers in classifying the credibility of disaster-related tweets.

In this paper, an unsupervised 10-point scoring model is proposed to evaluate the tweets’ credibility based on the user-based and content-based features. This technique could be used to evaluate the credibility of disaster-related tweets on future hurricanes and would have the potential to enhance emergency response during critical events. The comparative study of different supervised learning methods has revealed effective supervised learning methods for evaluating the credibility of Tweeter data.

The purpose of this study is to explore the current state of knowledge of sustainable entrepreneurship (SE) and to gain more insights from the articles originated from the emerging economies. This paper also sets an agenda for future research in this knowledge domain.

The authors perform a systematic literature review by analyzing the primary studies related to SE originating from emerging economies from Asia, Africa and the Middle East. This review scrutinizes a total number of 45 studies to explore the current state of research in this knowledge domain from such economies.

Overall, this review finds that SE research is still at the nascent stage, especially in the context of emerging economies. The authors elicit a few sub-themes, within the SE research, such as individual-level factors, organizational-level factors, institutional-level factors and cultural and social factors.

The authors present a few limitations of this study. Firstly, this study uses articles from the Scopus and Web of Science only. Secondly, this systematic review is limited to the articles originated from emerging economies of Asia, Africa and the Middle East. Thirdly, this review gives overall picture of the SE research in emerging economies and the same in other economies is not in the scope of this study.

The findings of this study will be helpful to the researchers to locate avenues for future course of research in SE field. This study helps the policymakers and educational institutions of emerging economies understand and ingrain sustainability element in entrepreneurship, and thereby helps them to fulfill sustainable economy and sustainable development goals.

To the best of the authors’ knowledge, this study is the first of its kind in the field of SE in emerging economies. This review gives more insights on the state of SE in the emerging economies, as these economies can significantly contribute to the realization of Sustainable Development Goals.

The purpose of this paper is to examine the moderating effect of media pressure on external directors in relation to disclosure of information on corporate social responsibility (CSR).

The paper adopts a multilevel approach, integrating the institutional, organisational and individual levels of analysis in a whole model that explains corporate transparency. The paper uses a sample composed of 98 non-financial listed Spanish companies for the period 2004-2010,

The results show heterogeneity between external board members. Proprietary directors, representing shareholders, tend to promote adoption of the Global Reporting Initiative guidelines in order to increase value for shareholders. On the contrary, independent directors are risk adverse in relation to the effect that CSR information disclosure could have on their professional reputations.

The sample could be improved, including companies from different countries and more years for the analysis, since the period studied comprises a particular economic setting (2008-2010), a global financial crisis.

Although these results from the Spanish context, the authors recommend that regulatory bodies incorporate provisions into good governance codes that guarantee the existence of quality and comparable CSR information that favours stakeholders’ decision taking.

The image that society has about a company comes from the opinions created from the mass media. The arguments proposed by agenda-setting theory can be managed by companies as a strategic mechanism to respond to society expectations. At present, two of the most studied aspects are the ethical and sustainable behaviours of organisations. These aspects are related to the characteristics of boards of directors, especially to external directors. Independent directors may disagree with disclosing information about CSR practices because they fear that this information would affect their professional reputations, since they are not specialised in these topics. However, proprietary directors favour the disclosure of this information in an attempt to reduce the cost of capital and risk perceived by investors, especially in more sustainable companies.

The difference between developed and less developed countries resides to a great extent in the effectiveness of their administrative systems. The objective of this study is to identify and analyse the organisational constraints acting upon and within the Egyptian Ministry of Education that deter its capacity for administrative reform. Critical management processes are examined, such as policy formation, promotion procedures, planning, resource distribution, and local level decision making. Field visits to several regional school systems, as well as interviews with most of the senior ministry officials, were carried out by a team of American and Egyptian researchers. The research is significant because it provides a close examination of a system closed to most Western researchers. The administrative structure of the Ministry will be of interest to scholars because, even though it is highly bureaucratic, it operates with relative efficiency. However, what it cannot do with any degree of effectiveness is change the educational system from its long‐established patterns.

Driven by the development of the global digital economy, knowledge management in industrial enterprises offers more possibilities for green innovation. Based on the perspective of external knowledge sources, this study aims to construct a panel regression model to explore the relationship between digital economy and industrial green innovation efficiency.

Panel data from 30 regions in China from 2011 to 2020 were selected as research samples. All data are obtained from national and provincial statistical yearbooks. Coupling coordination degree analysis, entropy method, panel regression analysis, robustness test and threshold effect test by Stata 16.0 were used to test the hypotheses.

The empirical results demonstrate the hypotheses and reveal the following findings: the digital economy is positively related to industrial green innovation efficiency and external knowledge sources, and external knowledge sources mediate the relationship between them. Moreover, based on the threshold test results, the digital economy has a double-threshold effect on industrial green innovation efficiency.

Based on the perspective of external knowledge sources, the proposed mediating mechanism between the digital economy and industrial green innovation efficiency has not been established previously, further enriching the research on the antecedents and outcomes of external knowledge sources. Moreover, this study estimated the direct influence mechanism and double-threshold effect of the digital economy on industrial green innovation efficiency from theoretical and empirical analysis, thus responding to the call of scholars and adding to existing research on how the digital economy affects the green transformation of industrial enterprises.
