Halal markets are rapidly growing in terms of market size and global coverage; therefore, there is a critical demand to have a deeper understanding of the consumption behavior of Muslim consumers. This study aims to explore the influence of using the Halal logo on Muslim consumers’ attitudes toward food products using the neuroscience technology of functional magnetic resonance imaging (fMRI).

The theory of planned behavior represents the foundation of this research, where consumer attitudes during an fMRI experiment were evaluated based on two different groups of images: images of just the Halal logo and images of meat labeled with the Halal logo. The study used the blocked design approach to track brain responses produced from displaying the two groups of images to study participants, where brain activity represents participants’ attitudes toward selecting the products.

There were no significant variations in brain activity when participants viewed Halal and non-Halal logos; in contrast, there were significant brain changes in the ventromedial prefrontal cortex region when meat images were labeled with Halal and non-Halal logos. This suggests that the Halal logo only has an influence on perception when it co-occurs with a product.

Tracking Muslim consumption patterns is important for managers to be able to establish strategies to target Muslim consumers. This study uses a unique technique to study the behavioral attitude of a rapidly growing market segment, which can help marketing managers tailor their advertisement strategies to be more effective.

Previous research on the consumption of Halal products uses conventional approaches to study the influence of the Halal logo; however, to the best of the authors’ knowledge, this study is the first to explore the influence of the Halal logo on Muslim consumers’ attitudes using fMRI technology.

The importance of innovation has attracted growing attention due to the complex and rapidly changing business environment. This study aimed, first, to examine the joint effect of servant and authentic leadership (AUL) styles on employee creativity (EC), second, to examine the direct and mediated effect of servant leadership (SL) on employees' innovative work behaviour (IWB), third, to examine the effect of EC on IWB and finally, to investigate the moderating effect of creative self-efficacy (CSE) on the relationship between AUL and EC.

A quantitative approach was used, and the data were collected from 446 employees in the Qatari public sector. The data were then analysed by employing partial least squares structural equation modelling (PLS-SEM) using SmartPLS software to validate the measures before testing the proposed model.

The results of this study emphasized the strong hypothesized link between EC and IWB. It also endorsed the mediating role of EC between SL and IWB and the moderating role of CSE in the AUL-EC relationship.

The originality of this study comes from various aspects. First, it is unique in separately examining EC and innovation and the link between them. Second, it investigates the joint impact of servant and AUL styles on EC. Third, it explores the mediating role of EC between SL and IWB. Fourth, the moderating effect of CSE on the AUL-EC link also was examined to gain a full understanding of the relation effect. Finally, the value of the current study also comes from the integration of the triangular theory of creativity, SL and AUL theories and self-efficacy theory to explain the proposed model of the study. Moreover, this study serves as a guideline for decision-makers on how to enhance IWB among employees by focusing on leadership programmes and the creative and innovative culture.

This study examines the influences of personality traits on the employees' commitment to change that moderated by the organizational culture. The employee's commitment to change is important for the large companies to sustain in the global economy.

The quantitative data were collected from the employees in the large companies that are listed in Bursa Saham Kuala Lumpur (BSKL) Malaysia. The research used a simple random sampling and a cross-sectional survey.

The results showed there is a relationship between the personality traits and the employees' commitment to change, moderated by the organizational culture.

This study implies that both practitioners and leaders need to review how they could increase the employees' commitment to change in the companies based on the various personalities.

The originality of the study is the establishment of the instruments and theoretical building on the personality traits, organizational change and employees' commitment to change.

The purpose of this research is to investigate how the negative effect of litigation risk on firm performance could be controlled through the channel of voluntary disclosure and under the condition of institutional ownership.

To get the objectives, the study analyzed an unbalanced panel of 918 non-financial listed Chinese firms from 2010 to 18. To capture any expected unobserved heteroscedasticity and autocorrelation in the unbalanced sample, the authors have applied fixed effect regression with robust standard errors clustered at the firms' levels as suggested by Newey and West (1987).

The research provides that the good disclosure practices and presence of institutional ownership in corporations raise the trust of the investors by making the corporate operation clear in the eyes of the stakeholders. This increases the corporate credibility and as consequence corporations are protected against litigation risk. Thus, in the light of the information asymmetry and signaling theories, voluntary disclosure practices, and financial institutions' ownership, bridges the information gap and transmit a positive signal in the market regarding the better financial performance of the corporations.

These findings are helpful for the corporate managers for effective strategic decisions, regulatory authorities for policy formulation, and individual investors for developing a diversified investment portfolio.

By applying the mediation and moderation effects, the research enhances the understanding of the underlying causes of the association between a firm's litigation risk and its performance. The current research contributes to the literature, that agency issues which create litigation risk could be settled internally with voluntary disclosure practices and externally with institutional ownership.

This study examines the effects of perceived leadership styles on the perceived creativity and innovation of public servants working in a rapidly developing country while shedding light on the internal causal dynamics of these effects.

Survey data are collected from 568 Qatari public servants working in a variety of public sector organizations. Data are analysed using structural equation modelling (SEM) employing SmartPLS.

A significant relationship between perceived leadership styles and public servants' self-perceived creativity is found, with psychological empowerment as a mediating variable. Public servants that perceive their leaders as conveying transformational, transactional and servant leadership styles are found to have significantly higher self-perceived creativity, whereas authentic leadership does not have a significant positive effect. This finding indicates that transformational, transactional and servant leadership styles appear to impact public servants' creativity. This impact corresponds with findings from research on the relationship between leadership styles and creativity in the private sector. The results of this study confirmed the mediating effect of psychological empowerment, apart from authentic leadership.

The findings shed light on the relationship between perceived leadership styles and the self-perceived creativity of public servants working in a rapidly developing country, its causal dynamics and how these effects relate to corresponding findings in the private sector. The ensuing practical implications offer guidelines on how to organize leadership to maximize creativity and innovation in the public sector, especially in rapidly developing countries.

The purpose of this paper is to empirically examine the effects of relational support, educational support and self-confidence on entrepreneurial intentions of undergraduate business students in a university.

To empirically validate the conceptual model and test the hypothesised relationships, the authors collected data from 227 business students at an AACSB-accredited university in Malaysia through random sampling.

The results were based on analyses from structural equation modelling using the SmartPLS software. The findings show that entrepreneurial intention of business students is significantly influenced by educational and relational support; however, the moderating effects of self-confidence in the relationship between educational support, relational support and entrepreneurial intention are not significant. The paper clearly shows that relational and educational supports are two important factors that can influence the entrepreneurial intention of university students.

This research contributes to literature on entrepreneurial motivations and intentions through its empirical findings of the hypothesised relationships. It theoretically contributes to existing knowledge by integrating relevant themes from entrepreneurial motivations theory and the theory of planned behaviour. Finally, it offers alternative recommendations to university authorities and policymakers about business students’ entrepreneurship intention.

The study examines employee perceptions of CSR relating to stakeholders in the telecommunication industry of Ghana. It also analyses the variations in CSR practices among the sampled telecommunication firms.

By means of a survey, the study explored from the perspective of employees the CSR practices of their firms highlighting the stakeholder group they perceive their firms to be focussing on. A self-administered questionnaire was used to gather data from employees working with leading telecommunication firms in Ghana. A total of 177 valid responses were used for the study analysis. Data was analysed by means of descriptive statistics, and differences in respondent views across the different firms were ascertained using analysis of variance test (ANOVA).

The study results demonstrate that although telecommunication firms engage in CSR activities in some respect, generally these activities are directed more at the stakeholder group “society” distantly followed by shareholder group. The authors also find from their target respondents that not so much attention is given to issues relating to the stakeholder group “the environment”. The results also suggest variations exist in the direction of CSR practices by these firms.

Managers of telecommunication firms in Ghana seem to balance the interest of stakeholders by focussing on society rather than prioritizing these stakeholders.

This study contributes to CSR studies highlighting the perception of employees on their companies' CSR practices while comparing practices amongst telecommunications firms. This would help management of these firms to map out strategies to direct their CSR activities based on stakeholder prioritization.

The study was designed to examine the predictors of information literacy self-efficacy skills (IL skills) of medical students.

The study was quantitative in nature and was carried out by using survey research method. Wong and Law Emotional Intelligence Scale (WLEIS) and Information Literacy Self-Efficacy Scale for medical students (ILSES-M) were used to collect the data. Data was collected randomly from 223 out of 526 undergraduate medical students on proportionally random basis according to the number of students available in each year. PLS-SEM analysis was run with the help of SmartPLS 3.2.

The findings of the study revealed that three subconstructs for emotional intelligence (EI), that is, self-emotions appraisal, others-emotion appraisal, use of emotions, had a statistically significant positive impact (p < 0.05) on information literacy (IL) self-efficacy of the medical students. The findings further confirm that English language proficiency and frequency of attended IL instruction sessions also have a significant positive impact on IL self-efficacy of medical students.

The exploration of EI in relation to IL is comparatively a novel area. The study observed the influence of EI level on IL self-efficacy of medical students. The study will be a significant contribution to the IL literature. The results may help the information professionals/librarians, particularly those who are engaged in teaching and designing IL programs.

The purpose of this paper is to present a new system frequency response model with participation of wind-hydro-thermal units to overcome frequency deviations.

The extracted minimum frequency equation is considered as a constraint in security-constrained unit commitment calculations. Because of high-order polynomials in the frequency transfer function and high degree of nonlinearity of minimum frequency constraint, Routh stability criterion method and piecewise linearization technique are used to reduce system order and linearize the system frequency response model, respectively.

The results of this paper indicate that by using this model, the hourly minimum frequency is improved and is kept within defined range.

This combined model can be used to evaluate the frequency of the power system following unexpected load increase or generation disturbances. It also can be used to investigate the system frequency performance and ensure power system security which are caused by peak load or loss of generation in presence of renewable energies.

This paper aims to design an adaptive nonlinear strategy capable of timely detection and reconstruction of faults in the attitude’s sensors of an autonomous aerial vehicle with greater accuracy concerning other conventional approaches in the literature.

The proposed scheme integrates a baseline nonlinear controller with an improved radial basis function neural network (IRBFNN) to detect different kinds of anomalies and failures that may occur in the attitude’s sensors of an autonomous aerial vehicle. An integral sliding mode concept is used as auto-tune weight update law in the IRBFNN instead of conventional weight update laws to optimize its learning capability without computational complexities. The simulations results and stability analysis validate the promising contributions of the suggested methodology over the other conventional approaches.

The performance of the proposed control algorithm is compared with the conventional radial basis function neural network (RBFNN), multi-layer perceptron neural network (MLPNN) and high gain observer (HGO) for a quadrotor vehicle suffering from various kinds of faults, e.g. abrupt, incipient and intermittent. From the simulation results obtained, it is found that the proposed algorithm’s performance in faults detection and estimation is relatively better than the rest of the methodologies.

For the improvement in the stability and safety of an autonomous aerial vehicle during flight operations, quick identification and reconstruction of attitude’s sensor faults and failures always play a crucial role. Efficient fault detection and estimation scheme are considered indispensable for an error-free and safe flight mission of an autonomous aerial vehicle.

The proposed scheme introduces RBFNN techniques to detect and estimate the quadrotor attitude’s sensor faults and failures efficiently. An integral sliding mode effect is used as the network’s backpropagation law to automatically modify its learning parameters accordingly, thereby speeding up the learning capabilities as compared to the conventional neural network backpropagation laws. Compared with the other investigated techniques, the proposed strategy achieve remarkable results in the detection and estimation of various faults.
