Abstract

Purpose

The purpose of this paper is to provide an improved genetic algorithm to solve 0/1 multidimensional knapsack problem (0/1 MKP), by proposing new selection and crossover operators that cooperate to explore the search space.

Design/methodology/approach

The authors first present a new sexual selection strategy that significantly improves the one proposed by (Varnamkhasti and Lee, 2012), while working in phenotype space. Then they propose two variants of the two-stage recombination operator of (Aghezzaf and Naimi, 2009), while they adapt the latter in the context of 0/1 MKP. The authors evaluate the efficiency of both proposed operators on a large set of 0/1 MKP benchmark instances. The obtained results are compared against that of conventional selection and crossover operators, in terms of solution quality and computing time.

Findings

The paper shows that the proposed selection respects the two major factors of any metaheuristic: exploration and exploitation aspects. Furthermore, the first variant of the two-stage recombination operator pushes the search space towards exploitation, while the second variant increases the genetic diversity. The paper then demonstrates that the improved genetic algorithm combining the two proposed operators is a competitive method for solving the 0/1 MKP.

Practical implications

Although only 0/1 MKP standard instances were tested in the empirical experiments in this paper, the improved genetic algorithm can be used as a powerful tool to solve many real-world applications of 0/1 MKP, as the latter models several industrial and investment issues. Moreover, the proposed selection and crossover operators can be incorporated into other bio-inspired algorithms to improve their performance. Furthermore, the two proposed operators can be adapted to solve other binary combinatorial optimization problems.

Originality/value

This research study provides an effective solution for a well-known non-deterministic polynomial-time (NP)-hard combinatorial optimization problem; that is 0/1 MKP, by tackling it with an improved genetic algorithm. The proposed evolutionary mechanism is based on two new genetic operators. The first proposed operator is a new and deeply different variant of the so-called sexual selection that has been rarely addressed in the literature. The second proposed operator is an adaptation of the two-stage recombination operator in the 0/1 MKP context. This adaptation results in two variants of the two-stage recombination operator that aim to improve the quality of encountered solutions, while taking advantage of the sexual selection criteria to prevent the classical issue of genetic algorithm that is premature convergence.

Abstract

Purpose

Sustainable development is an attempt to achieve three competing aims: economic development, social justice and environmental conservation. Localising sustainable development in the Arabian city might require a framework that originates from its reality manifested in the region’s history, culture and religion. Ibn Khaldun’s model seems suitable for planning a sustainable city in the Arab world. The purpose of this paper is to discuss suitability of Ibn Khaldun’s writing to localising sustainable development in the Arabian cities.

Design/methodology/approach

The paper used a qualitative research methodology. The researcher investigated the writings of Ibn Khaldun and other scholars who studied his work to derive lessons for planning the sustainable Arab city.

Findings

Many of Ibn Khaldun’s concepts lost their accuracy, meanings and intentions in the course of translating his work. Ibn Khaldun’s writings can be the source from which scholars, planners and city administrators derive lessons to assure the sustainable development of human settlements, particularly in the Arab region. The writings of Ibn Khaldun are relevant to the Arab countries. His writings are sensitive to the realities of the Arab world, including geography, environment, history, religion and culture. His writings can support efforts for localising sustinable development in the Arabian cities.

Originality/value

Interrogating Ibn Khaldun’s writings can enable scholars, planners, architects and city administrators to elaborate and implement plans for the sustainable Arabian city. The findings of the paper assure that Ibn Khaldun’s analysis is suitable for addressing the urban ills of the contemporary Arabian metropolis as they were in his time.

Abstract

Purpose

The authors empirically investigate the association between acquisition, ownership structure and accrual earnings management (AEM) on real earnings management (REM) using Gulf Cooperation Council (GCC)-listed firms' context.

Design/methodology/approach

The authors' sample consists of 1,892 firm-year observations for the period from 2007–2017, and the authors adopt a panel data approach in investigating the interrelationships in this study. The authors employ different econometrics approach to test the authors' hypotheses.

Findings

The findings reveal that acquiring companies engage more in AEM if compared to REM. In terms of ownership structure, institutional ownership and state ownership mitigate the engagement in REM, whereas foreign ownership is found to be an ineffective mechanism in reducing engagement in REM. The authors report similar findings on ownership structure for AEM. The authors also find that the GCC firms engage more in REM when the firms engage in AEM, suggesting a complementary relation between these two earnings management techniques. These findings are robust after controlling for different aspects including any endogeneity issue in the authors' models.

Originality/value

The authors' research highlights the importance of understanding REM and AEM dynamics in GCC context. Also, the authors' findings on ownership structure suggest that GCC-listed firms can gain from institutional and state ownership which restricts earnings management, improving firm transparency and subsequently impacting firm performance.

Abstract

Purpose

The purpose of this paper is to analyse the citations of scientific research on the concept of corporate social responsibility (CSR) from 1970 to 2014. In particular, several interconnected research questions were investigated: How did the conceptualisation of CSR change from 1970 to 2014? What is the general direction of the change? How does Islamic CSR emerge?

Design/methodology/approach

An in-depth analysis was performed with the use of the data analysis tool available in the Web of Science. The study categorises CSR into four areas: business ethics and corporate governance; management; marketing; and others. The first three categories were based on the Chartered Association of Business Schools’ Academic Journal Guide 2010 and 2015 (UK).

Findings

The findings reveal that 67.19 per cent articles have been published based on the ranked journals of Academic Journal Guide 2010 and 2015. The findings of the study will help to inform future areas of CSR. The top journals which published most articles from Academic Journal Guide 2015 are Journal of Business Ethics and Corporate Social Responsibility and Environmental Management.

Practical implications

The findings suggest that the remit of sustainability from Islamic perspective is wider. Islamic marketing, as an area, remains largely in need of empirical research. The business communities should successfully integrate Muslim communities into their marketing strategies.

Originality/value

To the best of the knowledge, this is the first study to explore citation analysis of general CSR literature and Islamic CSR. The study finds that there has been an increase in interest in this subject of CSR and Islam in the recent years. Future research is needed on theory and methodological analysis of general CSR field and Islamic CSR field.

Abstract

Purpose

The main issue is whether customers prefer convenience over Shariah compliance or the opposite when they decide their Islamic banking needs. The purpose of this paper is to explore why customers adopt Islamic banking products and services: Shariah compliance or convenience?

Design/methodology/approach

Using convenience sampling, 310 respondents’ data were collected through online survey. For testing the fit and hypotheses of the proposed model, AMOS 25 software and Smart-PLS 4.0 software have been used.

Findings

Attitude, Islamic value and convenience have significant determinants of Islamic banking products and services. Shariah compliance has no direct or indirect influence on neither intention nor actual behaviour to adopt Islamic banking services. Furthermore, gender has no such differential effect on the adoption.

Practical implications

Managers and marketers of Islamic banks may benefit from the findings of this study, which demonstrate fresh insights regarding the factors which help in strategy formulations to promote Islamic banking services.

Originality/value

The growth of Islamic banks, branches and windows is remarkable in both Muslim-majority and Muslim-minority countries in the world. This paper postulates the behavioural finance studies in Islamic banking and finance research stream by extending the theory of planned behaviour of Ajzen (1985) as all the three new constructs (Islamic value, convenienc and Shariah compliance) are statistically fit for further studies. However, only Islamic value and convenience are the two significant factors which drive customers to take decision in the proposed model. This study gives insights to the bankers and authority about the consumer behaviour.

Abstract

Purpose

This study contributes to examining the factors that drive the adoption of cryptocurrencies for financial transactions in the tourism and hospitality industries. This is crucial to develop tourism and hospitality and stimulate financial inclusion in developing and developed countries.

Design/methodology/approach

This research paper employs the SEM model and bootstrapping method on a sample of 417 French participants involved in tourism and hospitality industries to reveal the causal pathway between a set of independent factors and the willingness to adopt cryptocurrencies for financial transactions.

Findings

The empirical findings reveal that ease of use, perceived usefulness, social influence, and financial literacy increase the willingness to use cryptocurrencies. French hotels need to have a strategic orientation, to deal with customers, competitors and changing technological environment. The study also reveals that social influence and financial literacy reduce the level of perceived financial risk and thus, leads to increase the intention to adopt the new type of decentralized currencies.

Originality/value

In contrast to previous studies that focused on the volatility and risk of cryptocurrencies, this research employs a human-centric approach covering different factors that could lead to the adoption of the new type of currency for financial transactions in tourism and hospitality industries.

Abstract

Purpose

This study aims to investigate the relationship between financial inclusion and sustainable economic development in Indonesia by exploring the potential impact of Takaful. Specifically, the study seeks to examine the feasibility of leveraging Takaful as a means to foster financial inclusion and drive economic growth in Indonesia.

Design/methodology/approach

This study uses a qualitative analysis methodology, specifically using content analysis techniques, to investigate the relationship between financial inclusion and sustainable economic growth in Indonesia, focussing on the role of Takaful. The content analysis enables a systematic study of the data to identify trends and topics pertinent to Takaful and its potential to advance financial inclusion.

Findings

The study’s results reveal a direct causal link between economic growth and achieving financial inclusion through the use of Takaful. The findings also indicate a positive correlation between the increased presence of Takaful markets and accelerated economic growth.

Research limitations/implications

The study examines only the use of Takaful in achieving financial inclusion and sustainable economic growth in Indonesia. Nonetheless, the practical implications of this research are substantial, as they highlight the potential of Takaful to foster financial inclusion and stimulate economic growth in Indonesia.

Practical implications

This study contributes to the limited body of research on the relationship between financial inclusion and economic growth in Indonesia, specifically in the context of Takaful.

Originality/value

This study’s value lies in its exploration of an under-researched area, providing crucial insights into the potential of Takaful to promote financial inclusion and drive economic growth in Indonesia. The social implications of this study are also noteworthy, as increased financial inclusion and economic growth can positively affect poverty reduction, job creation and overall societal well-being in Indonesia.

Abstract

Purpose

This study aims to investigate the interplay between renewable energy development, unemployment and GDP growth within Bangladesh, India, Pakistan and Sri Lanka. The research underscores the significant role of renewable energy plays in stimulating economic growth and mitigating unemployment, offering crucial policy insights for sustainable growth in South Asia.

Design/methodology/approach

Utilizing the autoregressive distributive lag (ARDL) framework and Toda Yamamoto causality through the vector autoregressive (VAR) approach, the study analyzes the long-term and short-term impacts of these variables from 1990 to 2019.

Findings

This study reveals a significant co-integration among renewable energy consumption, unemployment and GDP growth in selected South Asian countries. The long-term estimation shows renewable energy consumption influences negatively economic progression in Bangladesh, with no notable correlation with unemployment. In contrast, Sri Lanka demonstrates an optimal relationship among all the variables. Short-run assessments reveal a significant positive relationship between renewable energy consumption and economic growth in India, while an inverse relationship is evident in Pakistan. Moreover, the relationship between unemployment and economic progression, the result shows a negative and significant relationship in India and Sri Lanka.

Research limitations/implications

The study emphasizes the need for policy development concerning renewable energy development, unemployment reduction and sustainable economic growth in South Asia. While limitations exist, future research can expand upon this work by incorporating varied data, additional countries or alternative modeling techniques.

Originality/value

This research offers a unique exploration into the multidimensional impacts of renewable energy consumption, unemployment and economic growth in the South Asian context, an area previously unexplored in such depth.
