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.

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.
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
The purpose of this study is to determine how project governance influences project success. According to the authors, such an effect is mediated by organizational support and project team cohesion. The direct and indirect effects of organizational support and project team cohesion provided helpful information. The authors’ objective is to contribute to the project management knowledge of how project team cohesion plays a significant role in project success.
Design/methodology/approach
Data were collected from 350 employees working in Pakistan’s oil and gas industry. Four prime oil and gas exploration companies were selected as samples based on their contribution to the revenue. SPSS v23 and AMOS v23 were used for constructing structural equation modeling and path analysis to examine the direct and indirect effects.
Findings
The results revealed that project governance is positively related to project success. Furthermore, organizational support and project team cohesion mediated the relationship between project governance and project success.
Originality/value
Team cohesion has been primarily a topic of interest in sports psychology literature, education and medical sciences. There is an expressed need to investigate team cohesion issues in the broad domain of organizational development, specifically the project management literature. This study contributed by discussing team cohesion in the project context. Second, project governance was investigated using the conservation of resources theory. The lens of intellectual capital was applied to examine intangible resources of project governance like rules, regulations and directives for project success.

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 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.
