Abstract

Purpose

This paper aims to estimate the performance of protective clothing used to resist puncture (anti-stab property).

Design/methodology/approach

Seven single-layer (one layer) samples were investigated in this research. The first three samples were already used for the purpose of (anti-stab property), manufactured from Du-Pont product (commercial samples). The rest of the samples were locally designed and manufactured for the same purpose. These seven samples have then been examined after been added in conjunction with WL Kevlar XP (S 104) witness multilayers (eight layers) panel to create which are called multilayer samples.

Findings

The results of the statistical analysis for one-way ANOVA illustrated significant effect for single layer samples for all properties. While for multi-layer samples, the results showed a significant difference for all variables except displacement. The Tukey post hoc test observed a significant effect for some samples; also, other samples show a non-significant effect between samples.

Originality/value

It was observed that the locally manufactured samples serve the purpose as (anti-stab samples) compared with the commercial samples. The radar chart shows that for single-layer sample, the fifth sample fulfill the highest radar chart area, whereas for multi-layer samples, the sixth sample achieved the highest radar chart area.

Abstract

Purpose

SOX Section 404 requires that public companies evaluate and have their auditors attest to the effectiveness of their internal control over financial reporting (ICFR). These companies compare their ICFR effectiveness to the Internal Control Frameworks issued by Committee of the Sponsoring Organizations of the Treadway Commission (COSO). This paper aims to examine whether the implementation of the 2013 Control Framework has a positive impact on the information environment of U.S. public companies.

Design/methodology/approach

The study sample comprises firms from the S&P 1500 index and the Russell 2000 index firms that filed their annual reports after December 15, 2014. This paper uses bid-ask spread as a primary measure of information asymmetry, while controlling for the simultaneous effects of the new COSO framework on trading volumes and price volatility.

Findings

This paper finds a significant reduction in bid-ask spreads – a proxy for an improved information environment – among our sample firms following the adoption of the 2013 Control Framework, leading us to conclude that the 2013 Control Framework represents a substantial improvement.

Research limitations/implications

This study specifically examines the impact of control frameworks on the information environment under SOX 404. Future research could explore other economic consequences associated with the adoption of the new COSO Framework. Additionally, it would be valuable to investigate whether the Cadbury model, which also qualifies as a “suitable” control framework under the SEC rules for ICFR assessments, produces similar or different outcomes. Future studies could also analyze the implementation details across all five components concerning the three types of objectives.

Practical implications

The findings will provide valuable insights for policymakers on the effectiveness of the COSO 2013 Framework in enhancing internal control reporting.

Social implications

The findings will also contribute to improving the information environment in the capital markets by guiding policymakers and regulators in assessing the effectiveness of the new COSO framework.

Originality/value

While extensive research has focused on the consequences of accounting and related internal control disclosures, there has been limited examination of how the underlying internal control benchmarks affect the quality and reliability of ICFR assessments and disclosures. This research aims to address this gap.

Abstract

Purpose

This paper aims to propose an optimized type-1 Sugeno fuzzy logic backstepping sliding mode controller (T1-SFL-BSMC) to control the altitude and rotational behaviour of a quadcopter. The proposed controller improves the performance of the system by overcoming the limitations of conventional trial-and-error techniques for BSMC gain design.

Design/methodology/approach

In this study, the type-1 Sugeno fuzzy logic controller (T1-SFLC) technique is proposed which dynamically modifies the BSMC gains. In addition, the parameters of T1-SFLC are further tuned by five different optimization techniques, namely, genetic algorithm, particle swarm optimization (PSO), pattern search (PS), simulated annealing (SA) and adaptive neural network (ANN).

Findings

The effectiveness of these optimization techniques in tuning the T1-SFLCs for the gain scheduled BSMC is evaluated in terms of time response metrics; rising time, settling time and root mean square error (RMSE) for altitude and rotational behaviour. The results demonstrated that PSO-optimized T1-SFL-BSMC provides better responses in terms of time response metrices with reduced rise and settling times and minimized RMSE when compared to other optimized T1-SFL-BSMC.

Originality/value

This paper proposes a novel approach for controlling quadcopters by combining fuzzy logic with a BSMC. It is then improved by using many optimization strategies. A more dependable and effective approach to controller design is provided by the suggested method, which is essential for unmanned aerial vehicle applications.

Abstract

Purpose

Even though it is widely used, reinforced concrete (RC) is susceptible to damage from various environmental factors. The hazard of a fire attack is particularly severe because it may cause the whole structure to collapse. Furthermore, repairing and strengthening existing structures with high-performance concrete (HPC) has become essential from both technical and financial points of view. In particular, studying the postfire behavior of HPC with normal strength concrete substrate requires experimental and numerical investigations. Accordingly, this study aims to numerically investigate the post-fire behavior of reinforced composite RC slabs.

Design/methodology/approach

Consequently, in this study, a numerical analysis was carried out to ascertain the flexural behavior of simply supported RC slabs strengthened with HPC and exposed to a particularly high temperature of 600°C for 2 h. This behavior was investigated and analyzed in the presence of a number of parameters, such as HPC types (fiber-reinforced, 0.5% steel, polypropylene fibers [PPF], hybrid fibers), strengthening side (tension or compression), strengthening layer thickness, slab thickness, boundary conditions, reinforcement ratio and yield strength of reinforcement.

Findings

The results showed that traction-separation and full-bond models can achieve accuracy compared with experimental results. Also, the fiber type significantly affects the postfire performance of RC slab strengthened with HPC, where the inclusion of hybrid fiber recorded the highest ultimate load. While adding PPF to HPC showed a rapid decrease in the load-deflection curve after reaching the ultimate load.

Originality/value

The proposed model accurately predicted the thermomechanical behavior of RC slabs strengthened with HPC after being exposed to the fire regarding load-deflection response, crack pattern and failure mode. Moreover, the considered independent parametric variables significantly affect the composite slabs’ behavior.

Abstract

Purpose

In the present era, the achievement of employee Islamic performance has become a significant challenge for organizations. The purpose of the study is to examine the effect of Islamic leadership on employee Islamic performance directly and indirectly by bridging the connections between employees’ Islamic organizational values, Islamic organizational culture, and Islamic work motivation among the employees of Egyptian banks.

Design/methodology/approach

The authors used quantitative methods in this study and based its findings on the data received from 312 respondents in response to a questionnaire.

Findings

By using SmartPLS 4, this study’s findings demonstrate that Islamic leadership has a positive and significant effect on Islamic organizational values, culture, employee Islamic performance and work motivation. While Islamic organizational values and Islamic organizational culture do not significantly impact employee Islamic performance, Islamic work motivation is a significant predictor of employee Islamic performance. On the one hand, Islamic organizational values and Islamic organizational culture do not mediate the relationship between Islamic leadership and employee Islamic performance. On the other hand, Islamic work motivation is a mediating variable that significantly develops the relationship between Islamic leadership and employee Islamic performance.

Practical implications

The study’s findings support policymakers and human resource management practitioners to develop plans and strategies which enhance the Islamic performance of organizations’ employees. In addition, this study’s findings provide insights for researchers and academicians in developing Islamic leadership within their organizations so that they operate by Islamic values and codes.

Originality/value

Finally, by offering an integrated model of Islamic leadership, Islamic organizational values, Islamic organizational culture and employee Islamic performance, this study’s findings fill the gaps in the context of bank employees in a developing country, namely, Egypt.

Abstract

Purpose

Message stream advertising (MSA) has become an increasingly popular option for advertising on mobile social media. However, MSA is often avoided by consumers, and this avoidance deserves more research attention. The purpose of this study is therefore to identify the underlying mechanism and key variables that affect consumer avoidance of MSA in the context of mobile social media.

Design/methodology/approach

A face-to-face survey was administered to current mobile users of WeChat (N = 438). Structural equation modeling was conducted to test the relationships in the research model.

Findings

Results revealed that mobile consumers employ mechanical avoidance methods (i.e. zipping, muting and zapping) against MSA. The findings also demonstrated that advertising intrusiveness (stimulus) is directly linked to negative emotions, perceived entertainment and sense of control (organism), which, in turn, relate to MSA avoidance (response).

Originality/value

The study contributes to the MSA avoidance literature by using the stimulus-organism-response model to deepen the understanding of consumers' MSA avoidance on mobile social media, and it suggests important managerial implications for advertising practitioners and platform operators.

Abstract

Purpose

This study aims to assess the effectiveness of the Shari’ah supervisory board (SSB) and its impact on risk-taking in the presence of a strong and effective board of directors (BoD) among Islamic financial institutions (IFIs) in Bangladesh.

Design/methodology/approach

This study is conducted as a sample and extracted data from bank annual reports of 16 IFIs in Bangladesh from 2011 to 2020. To overcome the endogeneity, the research has applied the two-step systems generalized method of moments model with Arellano−Bover and Blundell−Bond estimators.

Findings

The results indicated that the indices of BoD and SSB negatively influence each other’s credit risk, particularly in the Southeast Asian context, focusing on IFIs in Bangladesh. In addition, the SSB mediated risk-taking positively when coupled with a strong BoD.

Practical implications

This paper emphasizes how the multiple board systems and their impact on risk-taking make the unique governance structure. Risk-sharing, avoiding fixed-up interest rates and ethical investing are controlled by the dual board’s contributions to financial stability. SSB contributes significantly to improve the regulatory coordination and product innovation in the global financial system to combat unethical profits from society.

Originality/value

This study contributes to the literature gap of the dual board’s role of governance. It is believed to be one of the first studies that provide empirical evidence and theories on SSB’s mediating role in the context of socio-economic, cultural and policy with other similar contexts of subcontinent particularly in Bangladeshi’s IFIs.

Abstract

Purpose

This paper aimed at investigating the relationship between organizational climate for initiative, job autonomy, climate for innovation and innovative work behavior (IWB) in a developing economy context.

Design/methodology/approach

The study surveyed 444 manufacturing businesses in Morocco, collecting data from three sources: CEOs, middle managers and non-managerial employees in the production department. The data were analyzed using structural equation modelling, the Bayesian estimation approach and the bootstrapped moderated mediation technique.

Findings

This study revealed that middle managers’ job autonomy mediates the positive link between climate for initiative and middle managers’ IWB when climate for innovation is strong.

Practical implications

This study provides practical information for organizations intending to make their middle managers willing to be innovative in their job by granting them job autonomy and building favorable climates for initiative and innovation.

Originality/value

This research expands the human resource management and innovation literature by examining features of the work context (i.e. climates for initiative and for innovation, and job autonomy) as previous research has mainly focused on the context approach to work design (i.e. social environment of work design). The study highlights the role of middle managers as essential contributors to fostering innovations within their firms.

Abstract

Purpose

The effects of gendered views on employee voice are of great importance for knowledge sharing within public universities. Yet, they are still neglected by current human resource management and entrepreneurship literature. While strengthening themselves by reinforcing the strengths and opportunities, public universities can generate entrepreneurial opportunities through various knowledge-sharing mechanisms, including social networks and employee voice. This became a crucial lever for public universities to leverage competitive advantages and to support entrepreneurial activities through network knowledge-based sharing. For this purpose, this study aims to examine the various aspects of entrepreneurship via the voice of employees, emphasizing the moderating effect of gender and the mediating role of social networks on the link between employee voice and the entrepreneurial atmosphere of universities.

Design/methodology/approach

The authors collected survey data from a cross-sectional sample of 335 employees engaged in entrepreneurship activities within public universities in an emerging economy context and analyzed the data using partial least squares structural equation modeling (PLS-SEM) with the Smart-PLS software.

Findings

The PLS-SEM analysis found that different dimensions of the university entrepreneurial climate (communication, knowledge sharing and innovative climate) positively impact members’ voices within public universities. This effect is amplified by social networks, which are crucial for spreading knowledge among faculty, thereby fostering a more open and collaborative academic environment.

Research limitations/implications

When acting, the university top management team should encourage the generation and dissemination of entrepreneurial ideas to nurture a dynamic entrepreneurial atmosphere and social involvement, ultimately supporting sustainable competitive advantages through a culture of strategic knowledge sharing. The results have practical implications for university managers, entrepreneurship education actors, administrators, policymakers and entrepreneurial ecosystem actors, by demonstrating how social networks can amplify the dissemination of ideas and entrepreneurial spirit.

Originality/value

This research explores how entrepreneurship and social networks can help faculty members have a stronger influence in academic settings. It also fills in the gaps in knowledge about how human resource management and entrepreneurship can work together to create a more communicative and innovative academic environment. Additionally, this study brings new ideas to existing literature by looking at how gender differences can affect employee voice, particularly emphasizing the importance of women in leadership roles at universities. This study is also the first to delve into how entrepreneurship and social networks, along with gender perceptions, play a role in shaping the voice of employees in a public university.

Abstract

Purpose

This study aimed to investigate the impact of benevolent leadership on proactive customer service performance by creating a moderated mediation model. The model focuses on the role of harmonious passion as a mediator in the relationship between benevolent leadership and proactive customer service performance as well as the moderating influence of proactive personality on this mediation.

Design/methodology/approach

The model was tested using data from 339 immediate supervisor-subordinate pairs in eight five-star hotels in Egypt. Frontline service employees and their immediate supervisors completed separate questionnaires, and the responses were matched using identification numbers.

Findings

The results indicate that harmonious passion fully mediates the positive relationship between benevolent leadership and proactive customer service performance. Additionally, proactive personality was found to moderate the mediated relationship between benevolent leadership and proactive customer service performance through harmonious passion, such that the mediation was stronger for employees with higher proactive personalities.

Research limitations/implications

By testing the moderated mediation model, this study contributes to our theoretical understanding of the motivational mechanism through which benevolent leadership influences proactive customer service performance.

Originality/value

This research offers initial evidence of the mediating role of harmonious passion in the positive relationship between benevolent leadership and proactive customer service performance. The moderated mediation model extends existing findings by incorporating proactive personality as a significant moderator in explaining the impact of benevolent leadership on proactive customer service performance.
