Abstract

Purpose

The aim of this investigation is to make the Bessel beamformer fully automatic when it is combined with Root MUSIC (MUltiple SIgnal Classification) and is based on the array processing in the application of beamforming and Direction of Arrival (DOA) algorithm for source position. The concept is analyzed for modified Bessel beamformer with Root MUSIC to form a non-blind array processing technique which is then used to focus a beam towards a desired user and place nulls towards interferers for capacity improvement.

Design/methodology/approach

The idea is manipulated for modified Bessel beamformer with Root MUSIC relies on MATLAB software with the goal to obtain high efficiency in terms of signal recovery, directive gain by minimizing MSE and place nulls towards interferers.

Findings

The finding of the analysis is presented in adaptive environment and provided in the tables. The paper shows that the presented method leads to superior results and can be used as a better alternative in many practical applications to avoid operator involvement.

Research limitations/implications

The adaptive processes described in the paper are still limited to simulation due to non availability of real system for testing.

Practical implications

The paper can be extended to a next level by implementing the proposed algorithms in the real time environment using FPGA technology.

Originality/value

This is our original work that can offer scientific contribution to signal processing community and may provide better results as an automatic beamformer.

Abstract

Purpose

The purpose of this article is to assess the effect of religious fasting on the cognitive performance during the month of Ramadan among healthy fasting individuals.

Design/methodology/approach

30 students were recruited prior the month of Ramadan to compare their cognitive performance during and after fasting. The data on cognition score were collected in two phases during and after Ramadan on four occasions (two times in Ramadan and two times after Ramadan) using structured questionnaire. The level of cognition was assessed by using two approaches: mathematical problem solving and memory testing. Five questions of mathematical problem were given to the subjects and were different at each week. However, the level of difficulty was kept constant. The time and score were recorded for each respondent during and after fasting month. For the memory test, ten pictures of items of similar sizes were displayed for 30 seconds, and the subjects were asked to recall/list down the item shown in the pictures. The cognition scores were expressed as mean±SD, and repeated measures analysis test was used for differences in fasting and non‐fasting days.

Findings

As expected, during Ramadan meal frequency was lower and sleeping (nap) frequency was higher with shorter duration at night. The feeling of tiredness was higher compared to non‐fasting days. The level of cognition score for was not different during Ramadan compared to non‐fasting days. The result shows that the level of cognition is not affected in fasting.

Originality/value

The research shows that the cognition is not affected in Ramadan fasting.

Abstract

Purpose

This study aims to investigate the effectiveness of two types of social media videos used for destination image development: induced/commercial-oriented content and organic content (where content is made without commercial interest, such as vlogs classified as user-generated content).

Design/methodology/approach

Experimental research using “Emotive EEG” (electroencephalogram) in a controlled environment was conducted with 30 participants (20 males, 10 females), age range 18 to 26. Emotive EEG recording was performed while the participants watched both types of video clips. Test results for both groups indicate that induced content is preferred over organic content.

Findings

This study opens up future research avenues where neuromarketing’s “Marketer Friendly” EEG equipment can be applied to the customer selection process.

Originality/value

Marketing analysts can gauge the interest and response of customers on different types of social media video content for destination marketing based on the findings of this study.

Abstract

Purpose

This study aims to theoretically discuss and empirically test the mediating mechanism of psychological distress and the moderating effects of Islamic work ethics (IWE) in the relationship between despotic leadership and adaptive performance.

Design/methodology/approach

A three-wave survey was used to gather the data from middle managers and their supervisors of construction firms in Pakistan. The final sample consisted of 304 respondents and data analysis was performed through SEM analysis.

Findings

Despotic leadership enhances employees’ psychological distress which results in a negative impact on adaptive performance. In addition, IWE played a buffering role in mitigating the harmful impacts of despotic leadership on adaptive performance.

Originality/value

The study is among the pioneers that have investigated how despotic leadership impacts employees’ adaptive performance via the underlying mechanism of psychological distress through the conservation of resources and social exchange theory lens.

Abstract

Purpose

This paper seeks to explore the influence mechanism of differentiated empowering leadership on knowledge sharing and the moderating role of perceptions of organizational politics.

Design/methodology/approach

A paired-sample collection method is employed to conduct an empirical research study on 287 employees.

Findings

The results indicate that the direct effect of differentiated empowering leadership on knowledge sharing is not significant, but it has a significantly positive impact on their organizational cynicism. Moreover, organizational cynicism plays the sole mediating role between differentiated empowering leadership and knowledge sharing. Finally, the perceptions of organizational politics moderate the relationship between differentiated empowering leadership and organizational cynicism as well as that between organizational cynicism and knowledge sharing.

Originality/value

The research results demonstrate the specific mechanism by which differentiated empowering leadership influences knowledge sharing through the mediating role of organizational cynicism. In particular, the paper determines the distinct roles played by perceptions of organizational politics as boundary conditions within this mechanism.

Abstract

Purpose

Over time, there has been a rise in deviant behavior among hotel employees. This scenario motivates researchers and practitioners to address the issue. The study aims to examine the influence of socio-psychological factors (abusive supervision, workplace ostracism, work-family conflict and emotional exhaustion) on workplace deviance (interpersonal and organizational deviation) in the hotel industry with the moderating effect of interpersonal justice and perceived organizational support.

Design/methodology/approach

We gathered data from 416 employees in the hotel industry by employing a convenience sampling method and administered structured questionnaires. Subsequently, we conducted data analysis using structural equation modeling (SEM).

Findings

Results showed that abusive supervision had a direct impact on work-family conflict, emotional exhaustion and interpersonal and organizational deviation; similarly, workplace ostracism had a positive impact on work-family conflict, interpersonal and organizational deviation, but it did not significantly impact emotional exhaustion. Finally, interpersonal justice had significant moderators between abusive supervision and interpersonal and organizational deviation.

Originality/value

This study contributes to the extent of research on the antecedents of interpersonal and organizational deviance and the mediating roles of work-family conflict and emotional exhaustion. Secondly, this research developed an integrated conceptual framework for categorizing the causes of interpersonal and organizational deviance by checking the mediation effect of work-family conflict (WFC) and emotional exhaustion (EE). Perceived organizational support (POS) and interpersonal justice (IPJ) as moderators, which is an addition to earlier works in this field of research.

Abstract

Purpose

This study aims to determine the role of intellectual capital (IC) on financial performance (FP), the mediating effect of high-performance work practices (HPWPs) and the moderating role of big data analytics on the banking sector operating in Pakistan.

Design/methodology/approach

This study collected quantitative and cross-sectional data using structured questionnaire forms distributed to selected targeted respondents using a convenient sampling technique. The 518 useable questionnaires were analysed using the SmartPLS software through a structural equation modelling technique to test the proposed research hypotheses.

Findings

The study results revealed that IC has shown an impact on FP. The role of HPWP significantly mediates between IC and FP, while the moderating role of big data analytics remains insignificant.

Practical implications

This study highlights IC's role in enhancing FP in the Pakistani banking sector. It will bring a higher quality IC in the banking sector, and they will be better positioned to serve the community. Policymakers need to invest in IC and HPWP and utilise BDA, which will boost FP and uplift the quality of the banking sector.

Originality/value

This study extends the concept of IC and adds the theoretical role of HPWPs and big data analytics in the literature on IC, along with the contextual application. The study also develops a unique role of the integrated IC model theory with a relationship to the banking sector of Pakistan.
