Abstract
Purpose
The purpose of this paper is to study the effect of rotation and initial stress on magneto-thermoelastic material with voids heated by a laser pulse heating.
Design/methodology/approach
The analytical method used was the normal mode analysis technique.
Findings
Numerical results for the physical quantities were presented graphically and analyzed. The graphical results indicate that the effect of rotation, initial stress and magnetic fields are observable physical effects on the thermoelastic material with voids heated by a laser pulse. Comparisons are made with the results in the absence and the presence of the physical operators, also at various times.
Originality/value
In the present work, the authors shall investigate the effect of the rotation, initial stress, magnetic field and laser pulse on thermoelastic material with voids subjected to a laser pulse heating acting as a thermal shock. A comparison is also made between the two types (types II and III) of Green-Naghdi theory in the absence and the presence of the physical operators. Such problems are very important in many dynamical systems.

Numerical results for the temperature, the displacement components, the stress components and the volume fraction were presented graphically and analyzed the results. The graphical results indicate that the effect of gravity and magnetic fields are observable physical effects on the porous thermoelastic material heated by a laser pulse. Comparisons are made with the results in the absence and presence of the gravity and the magnetic fields, also at various times.
Originality/value
In the present work, the authors shall formulate a 2-D problem for the propagation of plane waves on the porous thermoelastic material influenced by the gravity and the magnetic fields subjected to a laser pulse heating act as a thermal shock. A comparison is also made between the two types II and III of Green-Naghdi theory in the absence and the presence of the gravity and the magnetic fields.

Abstract
Purpose
The purpose of this paper is to provide an extension of the Corporate Governance Reporting Initiative (CGI) 2004, which reports on Malaysia's first corporate governance ratings. Characteristics of firms with high and low scores in the corporate governance ratings are analysed by comparing companies based on their corporate governance ranking as reported in the CGI.
Design/methodology/approach
Firms are classified into those at the top 50 percent and the bottom 50 percent of the corporate governance ratings list to examine whether there are any differences in the characteristics of firms in both classified samples. The characteristics of firms that are being examined are firms' profitability, leverage, growth, market valuation, size, age, ownership structure and countries of operation based on the Logit analysis.
Findings
The result shows that firm size has a strong influence with corporate governance ratings, but not so for other variables tested.
Research limitations/implications
This study analyses only eight corporate characteristics. There are other measures that can represent firms' size such as market capitalization.
Practical implications
It is hoped that the traits found from the analysis will be able to provide additional information concerning corporate governance to interested parties. The characteristics revealed may probably be found to be essential elements in the development of effective and efficient corporate governance structure. The study could also help corporations in their short‐ and long‐term strategies.
Originality/value
This study bridges the gap of previous studies by using a complete set of governance standards on the analysis and directly identifies firms with certain scores of corporate governance and addresses issues related to these exceptional companies.

This research aimed to maximize the value of date exports for the Kingdom of Saudi Arabia.
Abstract
Purpose
This research aimed to maximize the value of date exports for the Kingdom of Saudi Arabia.
Design/methodology/approach
To achieve its objective, this study relied on secondary data and quantitative economic analysis represented by the Linear programming model.
Findings
This study showed that Saudi Arabia exports dates to the United Arab Emirates, Yemen, Kuwait, Turkey, Somalia, Jordan, Oman, India, Indonesia, Bangladesh Morocco, Lebanon, and others. The geographical concentration coefficient for the quantity and value of date exports was 35.05% and 34.74%, respectively, during the study period. Saudi Arabia exported a quantity of dates amounting to 83.08 thousand tons, representing 40.57% of the average total amount of Saudi dates exports during the study period, to Yemen, Somalia, India, Indonesia, Bangladesh, Egypt, China, Djibouti, Bahrain, and Ethiopia, at prices lower than the average export price of 1200.31 dollars/ton, and therefore the export policy needs to restructure the geographical distribution of date exports. Based on the models of geographical distribution, Saudi date exports value can be increased by 32.76–127.12 million dollars, meaning can be increased by 13.77% – 53.44%. In light of the results of the proposed models, this study recommends the need to restructure the geographical distribution of Saudi date exports so that the value of Saudi date exports can be increased by 127.12 million dollars from the current situation for the period 2017–2021.
Originality/value
The paper’s original contribution lies in its proposal to restructure the geographical distribution of Saudi date exports to increase the value of exports.

Abstract
Purpose
The purpose of this paper is to investigate the influences of fractional order, hydrostatic initial stress and gravity field on the plane waves in a linearly fiber-reinforced isotropic thermoelastic medium.
Design/methodology/approach
The problem has been solved analytically and numerically by using the normal mode analysis.
Findings
Numerical results for the temperature, the displacement components and the stress components are presented graphically and analyzed the results. The graphical results indicate that the effect of fractional order, hydrostatic initial stress and gravity field on the plane waves in the fiber-reinforced thermoelastic medium are very pronounced. Comparisons are made with the results in the absence and presence of hydrostatic initial stress and gravity field.
Originality/value
In the present work, the authors shall formulate a fiber-reinforced two-dimensional problem under the effect of fractional order, hydrostatic initial stress, and gravity field. The normal mode analysis is used to obtain the exact expression for the temperature, displacement components, and stress components. A comparison is also made between the three theories in the absence and presence of gravity field. Such problems are very important in many dynamical systems.

Abstract
Purpose
This paper aims to investigate the role of lean talent management (LTM) as a novel approach for optimising creativity in architectural design firms (ADFs) towards achieving divergent heritage sustainability (DHS).
Design/methodology/approach
To achieve the abovementioned aim, a mixed qualitative and quantitative methodology is designed to accomplish three objectives. First, investigating the relationship between heritage and urban development; types of heritage and the role of LTM in enhancing creativity in ADFs. Second, presenting and analysing six heritage-related case studies to assess the need for creative solutions based on extent of deterioration in three different places in Egypt. Third, outlining the results of a survey questionnaire conducted with a representative sample of ADFs in Egypt to investigate the role of LTM towards optimising creativity in ADFs for achieving DHS.
Findings
The extent of deterioration increased for modern heritage than old heritage. Conventional approaches adopted by ADFs failed to develop built environments that can bridge the gap between the diverse identities. Creativity was not optimised when talent management (TM) was integrated solely and architects failed to develop appropriate solutions. LTM use architects to allow expression of arts towards heritage sustainability through the built environment, in which they feel associated with physical heritage. Consequently, individuals’ intangible heritage is preserved in which they will less deteriorate the physical heritage. Hence, LTM is a paradigm shift that has a great potential for DHS.
Research limitations/implications
The survey questionnaire and case studies focused on the Egyptian context because the region is in critical need for effective creative solutions and for such research that is unprecedented in investigating this gap. However, findings are absolute and could be used at any country sharing the Egyptian context and wishing to achieve a DHS approach.
Originality/value
The research work presented in this paper is novel in approach as it integrates two divergent fields and highlights the concept of DHS with its threefold approach. In addition, the concept of LTM is proposed as a novel paradigm shift in which it has received scant attention especially relating to heritage sustainability. The proposed ideas represent a synthesis that is novel and creative in thought and adds to the existing body of knowledge for future research in LTM and DHS.

Abstract
Purpose
The purpose of this paper is to introduce the phase-lag models (Lord-Shulman, dual-phase-lag and three-phase-lag) to study the effect of memory-dependent derivative and the influence of thermal loading due to laser pulse on the wave propagation of generalized micropolar thermoelasticity. The bounding plane surface is heated by a non-Gaussian laser beam with a pulse duration of 10 nanoseconds.
Design/methodology/approach
The normal mode analysis technique is used to obtain the exact expressions for the displacement components, the force stresses, the temperature, the couple stresses and the micro-rotation. Comparisons are made with the results predicted by three theories of the authors’ interest. Excellent predictive capability is demonstrated at a different time also.
Findings
The effect of memory-dependent derivative and the heat laser pulse on the displacement, the temperature distribution, the components of stress, the couple stress and the microrotation vector have been depicted graphically.
Research limitations/implications
Some particular cases are also deduced from the present investigation.
Originality/value
The numerical results are presented graphically and are compared with different three theories for both in the presence and absence of memory-dependent effect and with the results predicted under three theories for two different values of the time.

Abstract
Purpose
The purpose of this paper is to draw a map of the general features of epistemological and critical concerns in contemporary Islamic philosophy. This study will not be confined to the domain of academic philosophy or to those who are professionals in the field of philosophy.
Design/methodology/approach
The paper adopted the critical rational approach in dealing with contemporary Islamic philosophy in the Arab world. The scope will include scholars from different fields of epistemology who tried to present a “vision” of the attitude that should be adopted in facing the challenges of the age and the problems of the nation on the epistemological level or the political, economic and social levels.
Findings
There is a need for a philosophy of action and progress rather than a philosophy that is based on abstract ideas and theories and of words/rhetoric. The ethics required to accomplish this ought to identify the attributes of the citizen who can reach self-actualization through legitimate means based on a progress agenda with theoretical and philosophical foundations.
Research limitations/implications
Because a critical rational approach can be dealt with from different perspectives, this paper will adopt the classification of the principal intellectual trends: the reformist, secular and liberal.
Practical implications
This paper covers a long time span to determine whether the philosophical projects have been effective.
Originality/value
This paper, which criticizes the philosophic projects that are theoretically unsound and that do not address real social problems (like poverty), argues the need for a philosophy of progress and action. This will lead to devising an agenda that addresses the challenges the society is facing and to finding alternative and creative solutions resulting in development.

The purpose of this study is to develop and thereafter validate a Sharīʿah-based FinTech Money Creation Free [SFMCF] model for Islamic banking.
Abstract
Purpose
The purpose of this study is to develop and thereafter validate a Sharīʿah-based FinTech Money Creation Free [SFMCF] model for Islamic banking.
Design/methodology/approach
The study has adopted a qualitative research methodology, using three approaches, namely, a survey of the literature to identify the research gap and the variables needed for developing the model, content analysis to construct the variables into a model and semi-structured interview with 10 experts in banking, Sharīʿah and Financial Technology (FinTech) to validate the SFMCF model.
Findings
The major findings of the study lie in developing the SFMCF model for Islamic banking, empirical validation of the model’s viability and acceptability and the implications for the main stakeholders of Islamic banks.
Research limitations/implications
The SFMCF model is specific to Islamic banking and its validation is based on the views of 10 experts.
Practical implications
The SFMCF would necessitate changes to the central bank regulatory framework, convince Islamic banks to forego their powers and advantages of creating money and enhance their abilities to fully adopt Sharīʿah-compliant FinTech.
Social implications
The proposed model if implemented would change positively the perception of the society particularly the stakeholders of Islamic banks and restore their trust and confidence about the direction of the institution toward achieving the Sharīʿah objectives.
Originality/value
The novelty of this work lies in developing and validating the viability and acceptability of the SFMCF model for Islamic banking.
