Abstract
Purpose
Heavy hex structural bolts have been used in a wide range of steel structures for many years. However, these structures remain susceptible to fire damage. Conducting fire experiments on full-scale steel structures is costly and requires specialized equipment. The main purpose of this research is to test, analyze and predict the behavior of ASTM A325 bolts under tension loading in simulated fire conditions and develop a reliable finite element model that can predict the response of similar bolts without the need for repeated testing.
Design/methodology/approach
The experimental work was conducted at the University of Wisconsin-Milwaukee, where an electric furnace was custom-built to test a bolted specimen in tension under elevated temperatures. A transient-state testing method was adopted to perform a group of tests on 12.7 mm (½”) – diameter A325 bolts. The tests were divided into two groups: the first one was used to calibrate the equipment and choose a final testing arrangement and the second group, consisting of four identical tests, was used to validate a finite element model.
Findings
The temperature-displacement and load-displacement response was recorded. The tested bolts exhibited a ductile fracture in which a cup-and-cone shaped failure surface was formed in the threaded section at the root of the nut. ASTM A325 bolts are widely used by engineers in building and bridge construction, the results of this research enable engineers to determine the behavior and strength of ASTM A325 bolts when such bolts when exposed to fire event.
Research limitations/implications
Structural bolts are used to connect structural members, and they are part of structural assembly. To study the behavior of the bolts, the bolts only were investigated in a fire simulated in a furnace. The bolts studied were not part of a structural assembly.
Practical implications
The results of this study enable engineers to evaluate the condition of ASTM A325 bolts when subjected to fire loading.
Originality value
Tests were conducted at the University of Wisconsin – Milwaukee’s structures laboratory to study the effect of fire on an ASTM A325 bolts. Many tests under fire loading have been performed by researchers on different components of steel structures, this study focuses on studying the behavior of ASTM A325 bolts which are widely used in the USA.

Abstract
Purpose
Nuts and bolts have been used as fasteners of steel structures for many years. However, these structures remain susceptible to fire damage. While conducting fire experiments on steel structures is sometimes necessary, to better understand their behavior, such experiments remain costly and require specialized equipment and testing facilities. This paper aims to present a highly accurate three-dimensional (3D) finite element (FE) model of ASTM A325 bolt subjected to tension loading under simulated fire conditions. The FE model is compared to the results of experimental testing for verification purposes and is proven to predict the response of similar bolts up to certain temperatures without the need for repeated testing.
Design/methodology/approach
A parametric 3D FE model simulating tested specimens was constructed in the ANSYS Workbench environment. The model included the intricate details of the bolt and nut threads, as well as all the other components of the specimens. A pretension load, a tension force and a heat profile were applied to the model, and a nonlinear analysis was performed to simulate the experiments.
Findings
The results of the FE model were in good agreement with the experimental results, deviations of results between experimental and FE results were within acceptable range. This should allow studying the behavior of structural bolts without the need for expensive testing.
Originality/value
Detailed 3D FE models have been created by the authors have been created to study the behavior of structural bolts and compared with experiments conducted by the authors.

This paper aims to propose a model for democratization of Islamic home financing to tackle the issue of sustainability of homeownership affordability.
Abstract
Purpose
This paper aims to propose a model for democratization of Islamic home financing to tackle the issue of sustainability of homeownership affordability.
Design/methodology/approach
A conceptual framework and fractional equity model (FEM) are developed to incorporate big data analytics, artificial intelligence and blockchain technology in an ecosystem for affordability and sustainability of homeownership via the proposed financing model. In addition, the FEM adopts the simulation approach to show its validity in terms of liquidity when compared with traditional home financing. In this regard, this paper is focused on developing and demonstrating the feasibility of a new financing model, rather than testing specific hypotheses or relationships. This is to propose the democratization model for Islamic Home Financing that will not benefit the prospective home buyers without compromising the profitability of the financial institutions.
Findings
The findings indicate that the proposed end-to-end solution within the financing ecosystem can lead to more efficient matching market between the buyers and sellers of houses, reduced transaction costs, greater transparency and enhanced efficiency which in the end could lead to lower costs of owning homes and sustained financial resilience among house owners. The findings indicate that the FEM model is able to increase homeownership with more elements of liquidity, marketability and sustainability for homebuyers.
Research limitations/implications
This research highlights the potential of big data and blockchain technology in democratizing Islamic home financing and evidence that the transfer of ownership is possible through tokenization. However, this will require a mature financing environment to adapt the technology for practical application.
Practical implications
The model proposes a solution to propagate shared prosperity among stakeholders such as the house buyers/owners, sellers, investors as well the government agencies. The proposed FEM model provides alternative home financing that is more marketable, flexible and sustainable for households/buyers and financiers.
Social implications
It is hoped that with the proposed financing ecosystem to promote affordability and sustainability of homeownership via big data analytics, artificial intelligence and blockchain technology can lead to greater financial resilience for homeowners which can then be translated to enhanced well-being, increased productivity and can further promote economic growth.
Originality/value
This research is a concept paper based on academic research and industry collaboration with a technology provider.

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.

Abstract
Pakistan had never been a place of serious and nuanced debate and contestation of politics of postcolonial critique, that is, the continuity of economic, political, and cultural dependency of newly independent countries (NICs) on ex-colonizers as pointed out by neocolonialism, dependency theory, and postcolonial theory, respectively. Instead, Pakistan is presented by extant liberal academic literature as a “failed nation” and a state dominated by the military and plagued by religious extremism. As opposed to this, through the literary and activists writings of Aziz-ul-Haq, this chapter will try to illustrate how cultural contestation of the nation-building project postindependence from British rule was a lot more complex and interesting in Pakistan. This was so because the nation-building project of Pakistan was, on the one hand, an amalgamation of Indo-Persian, Arab, Indian, and Western colonial and civilizational influences and, on the other hand, entailed suppression of resilient local and national cultures of its constituent nationalities developed over centuries. This was later expressed in ethno-nationalist politics. However, when it came to the politics of the marginalized in the late 1960s, there were important political, theoretical, and literary insights which caused a change in the direction of political practice in Pakistan, which paralleled the politics expressed by writers like Fanon and early Subaltern Studies influenced by the Naxal Movement in India. The contestation and confusion arising from this dialectic also entered Pakistan's literary and cultural sphere. This chapter not only tries to give a different postcolonial critique of the failure of nation-building project in Pakistan but, though at a preliminary level, is an attempt to separate the original postcolonial theory in its radical tradition from contemporary postmodern/poststructuralist postcolonial theory marked with pessimism and resignation.

To learn about the relationship between mental alertness and self-competence among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University.
Design/methodology/approach
The researchers used the experimental method by following the experimental design with two measurements, tribal and posterior, for two groups, one experimental and the other control, due to its suitability to the nature of this research. Research sample: the research community included female students stumbling in the scientific path of Rayyan, the second semester of the academic year 2020–2021 AD, where the researchers selected the research sample in a deliberate manner from the stalled students of 25 students and a random sample of 10 female students was withdrawn to conduct the exploratory study. The number of the basic research sample is 15 female students. Reasons for selecting the search sample: all of the sample members are female students stumbling in the scientific path of Al-Rayyan for the academic year 2020–2021 and all sample members agree to apply the research.
Findings
The researchers refer to this to the virtual psychological guidance program-specific objectives, as well as the follow-up of the scientific principles and principles and the legalization of the measurement tools used in the research and the diversity of the program within the parts of the program and the training sought to develop the ability to manage pressures and emotions and training in social skills, awareness and self-awareness and the use of exercises relaxation, breathing and modern self-help, as well as the use of different methods and techniques such as the method of dialogue, discussion, awareness of feelings and problem-solving, which led to a change in behavior and personal characteristics, which led to a change in behavior and personal characteristics, leading to the development of behavior and personal characteristics.
Originality/value
The study aims to design a hypothetical psychological counseling program as a method of health care and its effect on the level of mental alertness and the level of self-efficacy of students who have struggled to study at the Deanship of the preparatory year – Imam Abdul Rahman bin Faisal University. The researchers used the experimental approach and applied this study on a sample of 25 students from the students who failed to study at the Deanship of the preparatory year for the second semester of the academic year 2020–2021 AD and the most important results were that the psychological counseling program as a method of health care had a positive effect on improving the level of mental alertness and the level of self-efficacy among the students who had failed to study. There is a positive correlation between the level of mental alertness and self-efficacy of struggling students as a way of health care.

Abstract
Purpose
The purpose of this paper is to empirically investigate the effects of knowledge management (KM) enablers on KM processes in research universities and testing the direct relation between KM processes and OP. This study also proposes to examine the mediating role of intellectual capital (IC) and innovation in the relationship between KM processes and performance of universities.
Design/methodology/approach
Using a sample of 217 academic and administrative personnel from research universities of Pakistan, the hypothesized relationships were tested through partial least squares structural equation modeling technique.
Findings
The results reveal that KM enablers have a significant impact on KM processes. The results also indicate that KM processes influence organizational performance (OP) directly and indirectly through innovation and IC.
Practical implications
Findings of this study reinforce the corporate experience of KM and suggest how administrators of research universities and higher educational institutions can promote innovation and IC, which in turn enhance OP.
Originality/value
Despite the augmented importance of KM in higher education institutions or research universities, there is a dearth of studies that investigate the interplay of KM, innovation, IC and OP. This is one of the earliest studies that not only empirically investigate the interaction of KM enablers, KM processes and performance of research universities but also shed insights into the existing literature by simultaneously investigating mediating role of IC and innovation in the underlying relationship.

Abstract
Purpose
The purpose of this research is to investigate the effect of knowledge-oriented leadership on organizational performance of higher education institutions (HEIs) and examine the neglected mediating role of knowledge management (KM) processes and innovation.
Design/methodology/approach
Following the quantitative and cross-sectional research design, data were collected through self-administered questionnaire from 312 faculty members of HEIs of Pakistan. The partial least squares structural equation modelling data analysis technique was applied to test the hypothesized relationships.
Findings
The results indicate that knowledge-oriented leadership has direct and positive effect on organizational performance. Moreover, the findings reveal that KM processes and innovation partially mediate the effect of knowledge-oriented leadership on organizational performance.
Practical implications
This study underscores the imrportant role of knowledge-oriented leadership in HEIs. Findings of this research suggest that by exhibiting knowledge-oriented behaviours, managers of HEIs can effectively manage their knowledge assets, ensure successful implementation of KM processes and augment product and process innovation leading towards superior organizational performance.
Originality/value
This is amongst one of the first studies that proposes an integrated research model and examines interrelationships amongst knowledge-oriented leadership, KM processes, innovation and organizational performance in the context of HEIs.

Abstract
Purpose
The purpose of this research is to compare the board quality's (BQ) impacts on the financial performance (FP) of conventional and Islamic banks (IBs) after the Subprime financial crisis. The main reason is to help financial stakeholders choose the best performing and most appropriate bank type with its engagement based on the BQ index.
Design/methodology/approach
Based on the existing gap in previous researches and by using the GLS method (Generalized Least Squares method), the author compared the BQ's impacts on the FP of conventional and IBs. Settings of the FP and BQ were collected from 30 countries located on 4 continents. Two equal samples were tested; each of them is composed of 112 banks. The author concentrated only on the banks that have published regularly the banks' annual reports over the period 2010–2018.
Findings
Cylindrical panel results revealed that in conventional banks (CBs), the BQ has negatively affected banks' FP, while in IBs the BQ's impacts on the banks’' FP is ambiguous. Nevertheless, the positive impacts are more significant on the IBs' FP than the negative impacts on the IBs' FP.
Practical implications
The main practical contribution is the identification and distinction between the impacts of board determinants' quality on the shareholders' profits in the case of conventional and IBs. Hence, conventional or IBs which have a bad BQ will generate less FP and will be classified as a lender of bankruptcy danger for the bank customer. Besides, whatever the bank type, in a financial stable period, good BQ positively influences FP and provides a good impression to stakeholders. Otherwise, FP indicates that the banks suffer from the weaknesses of the board quality determinants.
Originality/value
Returning to the finance and banking governance literature, the author's article provides the first conditional and demonstrative analysis that detailed a logical comparative process to analyze the correlation between the board determinants' quality and the financial performance of conventional and IBs. However, previous research has always discussed the main role of the board as an internal governance mechanism on the FP separately in each bank type.
