Abstract

Purpose

Automated composition of semantic web services has become one of the recent critical issues in today's web environment. Despite the importance of artificial intelligence (AI)‐planning techniques for web service composition, previous works in that area do not address security issues, which is the focus of this paper. The purpose of this paper is to propose an approach to achieve security conscious composition of semantic web services.

Design/methodology/approach

The proposed approach called security conscious composition of semantic web services (SCAIMO) is based on the prior work, i.e. AIMO. The AIMO is an effective approach for web service discovery and composition based on AI‐planning, web service modeling ontology (WSMO), and description logic (DL). In this paper, definitions of secure matchmaking and web service composition are formalized based on DLs. Moreover, security capabilities and constraint types in the proposed SCAIMO framework are presented.

Findings

This paper proposes a secure task matchmaker which is responsible for matching security conscious tasks with operators and methods based on WSMO and DL to support the proposed SCAIMO framework. In addition, the paper implements and evaluates the SCAIMO using a test case and the result shows that the approach can provide an applicable solution.

Originality/value

The key contribution of this paper encompasses the new framework to support security capabilities and constraints during composition of semantic web services as well as the new secure task matchmaker.

Abstract

Purpose

The purpose of this study is to evaluate the potentials of nano-additives in enhancement of oxidation and thermal stability of biolubricants thereby, improving the resistance of dispersed nanolubricants to thermal degradation under elevated temperature.

Design/methodology/approach

This study evaluates the oxidation stability and tribological performance of nano-enhanced biolubricants. Graphene and maghemite nanoparticles at 0.1% volume concentration were dispersed into coconut oil. Oxidation stability was analysed using a thermal analyser to understand the effect of nano-additives on thermal degradation of lubricants under increasing temperature. In addition, tribological performance and viscosity of the tested lubricants were evaluated using a four-ball friction tester and viscometer according to American Society for Testing and Materials standards.

Findings

The results reveal that the oxidation stability of biolubricants dispersed with nano-additives improves due to delayed thermal degradation. The nano-enhanced biolubricants’ oxidation onset temperature was delayed by 18.75 °C and 37.5 °C, respectively, for maghemite (MGCO) and graphene (XGCO) nanolubricants. This improvement imparts the performance viscosity and tribological performance positively. For graphene-enhanced nanolubricant, 10.4% and 5.6% were reduced, respectively, in coefficient of friction (COF)and wear scar diameter (WSD), whereas 3.43% and 4.3% reduction in COF and WSD, respectively, for maghemite-enhanced nanolubricant compared with coconut oil. The viscosity index of nanolubricants was augmented by 7.36% and 13.85%, respectively, for maghemite and graphene nanolubricants.

Research limitations/implications

The excellent performance of nanolubricants makes them suitable candidate as sustainable lubricants for machining with regard to environmental benefits and energy saving.

Originality/value

The effect of graphene and maghemite nanoparticles on the oxidation stability and tribological performance of biolubricants has been investigated. It is an original work and yet to be published elsewhere.

Abstract

Purpose

This review paper seeks to enhance knowledge of how pre-loading affects reinforced concrete (RC) beams under fire. It investigates key factors like deflection and load capacity to understand pre-loading's role in replicating RC beams' actual responses to fire, aiming to improve fire testing protocols and structural fire engineering design.

Design/methodology/approach

This review systematically aggregates data from existing literature on the fire response of RC beams, comparing scenarios with (WP) and without pre-loading (WOP). Through statistical tools like the two-tailed t-test and Mann–Whitney U-test, it assesses deflection extremes. The study further examines structural responses, including flexural and shear behavior, ultimate load capacity, post-yield behavior, stiffness degradation and failure modes. The approach concludes with a statistical forecast of ideal pre-load levels to elevate experimental precision and enhance fire safety standards.

Findings

The review concludes that pre-loading profoundly affects the fire response of RC beams, suggesting a 35%–65% structural capacity range for realistic simulations. The review also recommended the initial crack load as an alternative metric for determining the pre-loading impact. Crucially, it highlights that pre-loading not only influences the fire response but also significantly alters the overall structural behavior of the RC beams.

Originality/value

The review advances structural fire engineering with an in-depth analysis of pre-loading's impact on RC beams during fire exposure, establishing a validated pre-load range through thorough statistical analysis and examination of previous research. It refines experimental methodologies and structural design accuracy, ultimately bolstering fire safety protocols.

Abstract

Purpose

This study aims to propose a temporary waqf model for family waqf by establishing its application parameters, which may facilitate the management of family waqf in Malaysia and encourage new donors to establish waqf.

Design/methodology/approach

A qualitative methodology was employed to analyse the data through deductive and field research methods. For field research, this study conducted semi-structured interviews with the Waqf Corporations and Mufti's Department in the selected states within Malaysia.

Findings

Results drawn from the interview's findings are that creating family waqf in Malaysia is hindered by several obstacles, including family waqfs not serving the public interest but rather their descendants, and family waqfs have been practised in perpetuity. Besides, inefficient management of family waqf and a lack of an effective mechanism and parameter exists. Therefore, this study presented a conceptual framework for a temporary cash waqf model for family waqf along with the parameters that can be used to implement it. The temporary waqf is a strategy to develop waqf property and the interests of creators, beneficiaries and trustees. Temporary waqf merged into the family waqf yields benefits to the family waqf.

Research limitations/implications

Because of Malaysia's Waqf Regulation and Administration, this study was confined to selected states. This study has broadened the scope of temporary family waqf, including moveable, immovable property and cash waqf.

Practical implications

This study presented a temporary waqf model for family waqf as a realistic mechanism and criterion for its practical implementation in Malaysia.

Social implications

This study could encourage new donors to establish waqf.

Originality/value

This study’s novelty lies in its attempt to highlight the importance of the temporary waqf model as a practical mechanism with holistic principles for its implementation in Malaysia to benefit the donors, their families and trustees. In addition to family waqf, numerous temporary waqfs may be established, in which the income or usufruct is shared proportionally, such as charitable waqf (waqf khairi), private waqf (waqf khas) and joint waqf (waqf mushtarak).

Abstract

Purpose

This paper aims to fill the noticeably fragmented zakat literature repertoire by empirically exploring stakeholders’ views toward zakat management performance issues based on a selected zakat institution (ZI) operating on a corporatized platform with corporate administrative style.

Design/methodology/approach

A quantitative approach using a questionnaire survey distributed to Muslims in the State which ZI is operating was adopted. A total of 448 usable responses are used in the analysis covering descriptive and mean difference.

Findings

The results indicate that managerial reform configuration in terms of corporatization has been viewed positively by stakeholders, translated into a comforting agreement score toward ZI’s improved management performance (collection, disbursement and reporting). Such perceptions are, however, observably sensitive to demographic factors of gender and employment type. The survey also document evidence that the corporatization exercise itself had improved respondents’ confidence toward ZI being the zakat administrator in the State.

Originality/value

The research contributes to the public policy debate with respect to corporatized ZI’s management performance from the stakeholders’ perspective. The results are arguably informative at various levels, forming a basis for reality check and policy inputs for various stakeholders, including (but not limited to) the ZI itself, zakat payers and asnafs, particularly in designing relevant and necessary administrative strategies and relevant policy formulation in addressing the performance and accountability issues in ZIs.

Abstract

Dynamism of digital economy requires innovation in the mobile payment system to provide for the free flow of information to facilitate electronic transactions. However, regulations and standards were introduced at the global and country levels to impose limitations on mobile payment system to protect consumers’ interests. The Malaysian government introduced the Anti-money Laundering, Anti-terrorism Financing and Proceeds of Unlawful Activities Act 2001 (Act 613) (AMLA) to protect the people from being involved in offences both locally and internationally and an unlawful activity carried out physically or by using virtual mechanisms. It is argued in this study that AMLA has hindered the innovation of the digital economic system that is promoted by the government in line with global developments. The research method adopted is personal interview with selected respondents to gather their views on the challenges posed by the restrictions imposed by AMLA that has had the impact of limiting innovations in the mobile payment system sector.

Abstract

Purpose – This study analyses the potential of cash waqf for the socio-economic development of Kelantan state. A cash waqf scheme was established by the Kelantan Islamic Religious Council (Majlis Agama Islam Kelantan or MAIK) in an effort to contribute to the socio-economic development of the Muslim community in that state.

Methodology/approach – A qualitative method of data acquisition through interviews. Among the informants interviewed were persons well versed with waqf and Islamic affairs, and several relevant public persons in Kelantan.

Findings – The results indicate that the people of Kelantan are optimistic about the success of cash waqf, although the implementation of this instrument is still in its infancy there. The socio-economic development factors of the economy, education, well-being, agriculture, health and religious affairs can be improved with the implementation of cash waqf.

Originality/value – This chapter is the first attempt to discuss the potential of cash waqf in Kelantan.

Abstract

Purpose

The aim of the paper is to identify the key factors that affect Guinean family business (FB) succession planning. The study also evaluates the impact of these factors on the succession planning process to ensure business continuity.

Design/methodology/approach

This descriptive quantitative research is based on a survey of 383 family businesses FBs in Conakry, the capital city of Guinea. The structural equation model (SEM) was used to analyze and validate the model featuring factors that influence family business FB succession planning (FBSP). The Theory of Stewardess and the Theory of FB Rivalry have been employed in the study.

Findings

While the incumbent attributes, firm attributes, and estate tax were revealed to have no significant influence on succession planning, the successor attributes and the family relationship significantly affected succession planning. Besides, undesirable domestic relationships among children of different mothers from polygamous families had an indirect impact on business succession planning.

Research limitations/implications

The limitations of the study include the population of the FBs being restricted only to those located in Conakry, the capital city. The study did not consider other regions and cities of Guinea. Besides, the grouping of attributes or characteristics was problematic, and studying each attribute separately as an independent variable would be much better. Finally, the limited literature and available data on Guinean FBs in general and succession planning generalize the findings to be done cautiously. Therefore, more studies are needed on FB succession in the country to further confirm these findings.

Social implications

The study may help ensure social solidarity based on the findings of factors associated to polygamous families in relation to businesses.

Originality/value

Few studies have been done on FBs in Conakry. Besides, putting attributes or characteristics into categories has been presented. Moreover, there is inadequate relevant literature and data on Guinean FBSP. Considering these limitations, the generalization of the findings should be done with caution. Therefore, this study touched on the issue of family business succession in Guinea which substantiates the findings.
