The purpose of this paper is to examine the effects of Darcian drag force and radiation-conduction on unsteady two-dimensional magnetohydrodynamic flow of viscous, electrically conducting and Newtonian fluid over a vertical plate adjacent to a Darcian regime in presence of thermal radiation and transversal magnetic field. A well-tested, numerically stable Crank-Nicolson finite-difference procedure is employed for the conservation equations. Excellent agreement is obtained for numerical solutions with previously published work.

In this investigation, an efficient, accurate, extensively validated and unconditionally stable finite-difference scheme based on the Crank-Nicolson model is developed to solve the governing coupled, non-linear partial differential equations. The accuracy and effectiveness of the method are demonstrated.

Different numerical results are obtained and presented graphically to explain the effect of various physical parameters on the velocity and temperature profiles, local, as well as average, skin friction and Nusselt number. It is found that, with a rise in Darcian drag force, flow velocity and temperature are reduced, but increased for all times. Both average and local skin frictions are reduced considerably with an increase in Darcian drag force, but reversed behavior is observed for the local Nusselt number. Increasing the thermal radiation effects accelerated the flow velocity as well as the fluid temperature and wall local skin friction in a saturated porous medium, but effectively reduced the local Nusselt number and average Nusselt number at the wall. Comparison with previously published works in the limits shows excellent agreement.

The analysis is valid for unsteady, two-dimensional laminar flow of an optically thick no-gray gas, electrically conducting, and Newtonian fluid past an isothermal vertical surface adjacent to the Darcian regime with variable surface temperature. An extension to three-dimensional flow case is left for future work.

Practical interest of such study includes applications in electromagnetic lubrication, boundary cooling, bio-physical systems and in many branches of engineering and science. It is well known that the effect of thermal radiation is important in space technology and high temperature processes. Thermal radiation also plays an important role in controlling heat transfer process in polymer processing industry.

This paper aims to investigate how do Muslims, Christians and Kaharingan adherents conduct interreligious relations among them in their everyday lives in Central Kalimantan; why do these religious communities observe interreligious relations as such; and what makes this model of interreligious relations.

The corpus for analysis comes from in-depth interviews with 20 persons, which took place between August and October in 2016 in Palangka Raya city and Kotawaringin Timur Regency in Central Kalimantan Province, Indonesia. The informants were selected from groups believed to be lay members and elites of Muslim, Christian and Kaharingan communities using snowball sampling technique facilitated by local research assistants. These informants are mainly mainstream Muslims, Christians and Kaharingan adherents.

The way to peaceful and co-existence life lived by religious communities in Indonesia is closely related to its rich treasures and precious tradition of cultural heritage: Indonesian communalism, Indonesian community spirit as seen in terms such as “tradisi hidup bersama,” “semangat kebersamaan” and “satu keluarga.” Instead of emphasizing the divisive differences among communities with various religious backgrounds, Muslims, Christians and Kaharingan adherents in Central Kalimantan create “third spaces,” common grounds shared by these religious communities at individual, institutional and societal levels.

Based on empirical findings, this research argues that the practices of peaceful and co-existence life lived by diverse religious communities in Indonesia relate to their particular social-cultural contexts of rich treasures and precious tradition of cultural heritage in the forms of Indonesian communalism and community spirit. Instead of emphasizing the divisive differences among themselves, various religious communities in Central Kalimantan create third spaces, common grounds between them and are shared by them at individual, institutional and societal levels.

This study explores central questions related to the connection between intellectual capital (IC) and the innovative performance of organizations through the mediating role of management control systems (MCS) and business strategies, as well as the moderating role of innovation capabilities.

The data was collected from the managers of small and medium enterprises (SMEs) through a structured questionnaire. Out of 1,152 questionnaires distributed, only 415 were used for analysis purposes. Structural equation modelling (SEM) was used to test the study hypotheses.

Intellectual capital significantly influences MCS, business strategies and innovative performance. Moreover, MCS, business strategies and innovative capabilities significantly improve innovative performance. MCS and business strategies significantly mediate the relationship between intellectual capital and innovative performance. Finally, innovative capabilities significantly moderate that between intellectual capital and innovative performance.

The current research examines how management should use MCS, business strategies, and innovative capabilities to take maximum benefit from intellectual capital in order to improve innovative performance.

This is pioneering research that develops a theoretical model to incorporate intellectual capital, MCS, business strategies, innovative capabilities and innovative performance. Even though the influence of various kinds of intangible assets/resources on innovative performance has been widely examined in the literature, scant attention has been paid to the role of MCS, business strategies, and innovative capabilities in leveraging the firm's intellectual capital.

This study aims to examine the institutional investors’ preferences for internal governance mechanisms (internal audit function and audit committee effectiveness) in an emerging country like Malaysia.

A sample of 2,020 yearly firm observations in Bursa Malaysia over the period 2009-2012 is used. The two-stage least squares using instrumental variables (IV-2SLS) analysis is used to examine the relationships. To corroborate the findings of this study, a regression based on a one-year lag of the independent variables is used. Furthermore, ordinary least square regression and Generalized Method of Moments using instrumental variables (IV-GMM) are used.

Positive associations are found between the internal audit function and audit committee effectiveness and the institutional ownership.

These findings imply that institutional investors gravitate to firms that have high investment in internal audit function and effective audit committee. These findings are consistent with the conjecture that institutional investors try to minimize monitoring and exit costs and meet their fiduciary responsibility by investing in better internal audit firms.

This study offers insights to policymakers interested in enhancing internal governance mechanisms to attract institutional investors.

Limited empirical studies have examined the relation between internal governance mechanisms (internal audit function and audit committee effectiveness) and institutional ownership. This study adds to the existing literature on the importance of internal governance mechanisms by documenting an association between internal audit function and audit committee effectiveness and institutional ownership in an emerging country like Malaysia.

This study aims to explore the interaction of strategic knowledge management (SKM) and innovation on the performance of large manufacturing firms (LMFs) in Malaysia.

This study used a quantitative approach in investigating this interaction. Smart partial least-squares analysis was performed to test the hypotheses.

It was observed that administrative innovation, process innovation and product innovation were effective drivers of LMF performance. It was also ascertained that SKM has no moderating effect on the product innovation relationship with performance, although it does moderate the relationships between LMF performance and administrative innovation and process innovation, respectively.

The main limitation of this study is its focus on Malaysian LMFs. It nevertheless contributes to the literature by extending understanding of SKM and innovation dimensions from multi-faceted perspectives. As this is largely ignored in the literature, the study paves the way for additional research.

The findings may be used as guidelines for chief executive officers, particularly on the way SKM and innovation can be developed for enhanced LMF performance, in the context of South Asian countries.

To the best of the authors’ knowledge, this is the first empirical work to confirm the main drivers of SKM, including in the analysis the effect of administrative innovation, process innovation and product innovation and performance, in the context of the manufacturing sector. In support of an original conceptual model, the insights contribute to the literature on innovation, LMFs, SKM and emerging economies.

This study argues that in order to address the problems associated with the modern market economy at their core, such as persistent poverty, growing inequality and environmental degradation, it is imperative to re-assess the well-being and moral philosophy underpinning economic thinking. The author attempts to offer a preliminary way forward with reference to the Islamic intellectual tradition.

This study employs content analysis of classical and contemporary Islamic texts on human well-being and economic ethics to derive a conceptual well-being model. The paper is structured in four sections: section one provides an overview of relevant secondary literature on moral economic approaches; section two outlines the main well-being frameworks; section three discusses the concept of human well-being in Islam informed by the Islamic worldview of tawḥīd, the Islamic philosophy of saʿādah, and the higher objectives of Islamic Law (maqās_.id al-Sharīʿah); and finally, section four discusses policy implications and next steps forward.

A conceptual model of human well-being from an Islamic perspective is developed by integrating philosophical insights of happiness (saʿādah) with an objective list of five essential goods: religion (Dīn), self (Nafs), intellect ('Aql), progeny (Nasl) and wealth (Māl) that correspond to spiritual, physical and psychological, intellectual, familial and social, and material well-being, respectively.

Further research is needed to translate this conceptual model into a composite well-being index to inform policy and practice.

This model can be used to review the performance of the Islamic finance sector, not solely in terms of growth and profitability, but in terms of realising human necessities, needs and refinements. It can also provide the basis for the Organisation of Islamic Co-operation (OIC) countries to jointly develop a well-being index to guide national and regional co-operation. More generally, this study highlights the need for research in Islamic economics to be more firmly rooted within Islamic ontology and epistemology, while simultaneously engaging in productive dialogue with other moral schools of economic thought to offer practical solutions to contemporary challenges.

This study offers three aspects of originality. First, by outlining well-being frameworks, it highlights key differences between the utilitarian understanding of well-being underpinning modern economic theory and virtue-based understandings, such as the Aristotelian, Christian and Islamic approaches. Second, it provides a well-being model from an Islamic perspective by integrating the Islamic worldview of tawḥīd, the Islamic philosophy of saʿādah, and the higher objectives of Islamic Law (maqāṣid al-Sharīʿah). Third, it proposes an ethical framework for informing economic policy and practice.

This study aimed to determine the relationship between calorie and macronutrients intake and the growth status of Aboriginal children based on gender and age group.

This was a cross-sectional study participated by 85 school-aged Aboriginal children at Labu, Negeri Sembilan. The dietary intake and socioeconomic status data were collected from the parents using an interviewer administrated structured-questionnaire and 24-hour dietary recall. WHO AnthroPlus software was used to determine the z-score of weight for age (WAZ), height for age (HAZ) and body mass index (BMI) for age (BAZ).

The mean fat intake was significantly higher among younger children (i.e. 7–9 years old) as compared to elder children (i.e. 10–12 years old) (40.7 ± 17.3 g vs 32.0 ± 13.8 g; t = 2.496, p = 0.015) but not for the mean intake of calorie (1816.1 ± 979.9 kcal vs 1566.3 ± 808.7 kcal; t = 1.248, p = 0.216), protein (50.13 ± 20.08 g vs 44.94 ± 16.45 g; t = 1.269, p = 0.208) and carbohydrates (198.0 ± 63.0 g vs 190.8 ± 66.1 g; t = 0.513, p = 0.609). The majority of the respondents did not meet recommended nutrient intake (RNI) for the calorie (65.9%) and fat (75.3%). A significantly higher proportion of elder children did not meet RNI for fat as compared to younger children (88.8% vs 65.3%; X² = 6.21, p = 0.021). The HAZ showed that 28.2% (n = 24) of the Aboriginal children were stunted, while WAZ showed that 14.8% (n = 9) of the Aboriginal students were underweight, and 8.2% of them were overweight. Based on BAZ classification, 15.4% (n = 6) of boys and 2.2% (n = 1) of girls were overweight. There is no significant correlation between calories and macronutrients and growth status of the children.

Although the under-nutrition status among Aboriginal children is still a highlighted issue, the few over-nutrition statuses among Aborigines should be taken into count, especially in term of energy and macronutrient intake.

This study aims to investigate the daily performance of the proposed microgrid (MG) that comprises photovoltaic, wind turbines and is connected to the main grid. The load demand is a residential area that includes 20 houses.

The daily operational strategy of the proposed MG allows to vend and procure utterly between the main grid and MG. The smart metre of every consumer provides the supplier with the daily consumption pattern which is amended by demand side management (DSM). The daily operational cost (DOC) CO2 emission and other measures are utilized to evaluate the system performance. A grey wolf optimizer was employed to minimize DOC including the cost of procuring energy from the main grid, the emission cost and the revenue of sold energy to the main grid.

The obtained results of winter and summer days revealed that DSM significantly improved the system performance from the economic and environmental perspectives. With DSM, DOC on winter day was −26.93 ($/kWh) and on summer day, DOC was 10.59 ($/kWh). While without considering DSM, DOC on winter day was −25.42 ($/kWh) and on summer day DOC was 14.95 ($/kWh).

As opposed to previous research that predominantly addressed the long-term operation, the value of the proposed research is to investigate the short-term operation (24-hour) of MG that copes with vital contingencies associated with selling and procuring energy with the main grid considering the environmental cost. Outstandingly, the proposed research engaged the consumers by smart meters to apply demand-sideDSM, while the previous studies largely focused on supply side management.

This study aims to elucidate the machining properties of low-cost expanded clay-reinforced syntactic foams by using different neural network models for the first time in the literature. The main goal of this endeavor is to create a casting machining-neural network modeling flow-line for real-time foam manufacturing in the industry.

Samples were manufactured via an industry-based die-casting technology. For the slot milling tests performed with different cutting speeds, depth of cut and lubrication conditions, a 3-axis computer numerical control (CNC) machine was used and the force data were collected through a digital dynamometer. These signals were used as input parameters in neural network modelings.

Among the algorithms, the scaled-conjugated-gradient (SCG) methodology was the weakest average results, whereas the Levenberg–Marquard (LM) approach was highly successful in foreseeing the cutting forces. As for the input variables, an increase in the depth of cut entailed the cutting forces, and this circumstance was more obvious at the higher cutting speeds.

The effect of milling parameters on the cutting forces of low-cost clay-filled metallic syntactics was examined, and the correct detection of these impacts is considerably prominent in this paper. On the other side, tool life and wear analyses can be studied in future investigations.

It was indicated that the milling forces of the clay-added AA7075 syntactic foams, depending on the cutting parameters, can be anticipated through artificial neural network modeling.

It is hoped that analyzing the influence of the cutting parameters using neural network models on the slot milling forces of metallic syntactic foams (MSFs) will be notably useful for research and development (R&D) researchers and design engineers.

This work is the first investigation that focuses on the estimation of slot milling forces of the expanded clay-added AA7075 syntactic foams by using different artificial neural network modeling approaches.
