Abstract

Purpose

The purpose of this paper is to examine how residents in Qatar, the host country of the 2022 World Cup, interact, socialize and acculturate in order to create a more harmonic society, a critical factor for the event delivery and preparations.

Design/methodology/approach

Data were collected from Qatari nationals and expatriates residing in the country of Qatar using a survey. A stratified random sampling approach was applied using as sampling framework all households having a mailing address with the country’s electric company. In total, 2,398 Qataris were contacted and 1,020 completed the survey. From the expatriate population, 1,852 were contacted and 1,134 completed the survey.

Findings

The results showed Qatari nationals were favorable toward Arab and Asian expatriates but not as favorable as Arab and Asian expatriates were toward them. Both groups of residents showed high quality of life (QOL) perceptions, with the locals having slightly higher QOL. Finally, Asian expatriates were more open to socializing with the locals and Arab expatriates.

Research limitations/implications

The results of the study shed light into the acculturation process in host societies of mega sport events such as the 2022 World Cup in Qatar.

Originality/value

This is the first study that examined a mega event’s host country resident’s cultural interactions to identify potential issues that can arise and interfere with the event experience of the 2022 World Cup in a very diverse society.

Abstract

Purpose

The purpose of this study is to present a new methodology of selective harmonics elimination (SHE) technique suitable for single-phase photovoltaic (PV) tied pulse width modulated (PWM) inverter.

Design/methodology/approach

In the proposed SHE, switching angles for inverter control are determined offline through numerical techniques and stored in a microcontroller memory as a function of modulation index (md). The methodology uses the solution that leads to a lower change of switching angles from the previous modulation index (md) for storing in the processor memory for multiple solutions. This leads to a smaller number of sections when a piecewise mixed model is considered for storing the entire switching angle curve for the online inverter control. The proposed idea is simulated and experimentally validated on a laboratory prototype of PV (500 W) grid-tied PWM inverter. The control environment is then realized in NI c-RIO 9082.

Findings

This proposed technique is suitable for limiting voltage total harmonics distortion (THD) in single-phase PV tied grid connected voltage source inverter (VSI). Moreover, it is found that filter (L-C) size requirement is less.

Originality/value

The proposed SHE with piecewise mixed model technique effectively reduces voltage THD with less filter size (L-C) in a single-phase PV-tied system.

Abstract

Purpose

The aim of this paper is to study pharmacy service impact on patient satisfaction and to determine what factors saliently link with pharmaceutical service performance at Hamad General Hospital.

Design/methodology/approach

A patient satisfaction questionnaire was designed using the literature and consultation with Hamad General Hospital medical experts. The questionnaire contained 22 items that focused on five influencing factors: promptness; attitude; supply; location; medication education; and respondent demographic aspects. A total of 220 respondents completed the questionnaire. An exploratory factor analysis was used to group items and a structural equation model was developed to test causality between five factors along with their influence on patient satisfaction.

Findings

The study establishes statistical evidence that patient satisfaction is positively influenced by service promptness, pharmacist attitude, medication counseling, pharmacy location and waiting area. Several socio‐demographic characteristics have statistically different effect on satisfaction, notably: gender; marital status; health status; age; educational level; and ethnicity. However, medication supply did not influence patient satisfaction.

Practical implications

Pharmaceutical services are recognized as an essential healthcare‐system component. Their impact on customer satisfaction has been investigated in many countries; however, there is no such study in Qatar.

Originality/value

The findings identify pharmaceutical service performance indicators and provide guidelines to improve Qatari pharmaceutical services.

This study aims to present a modified interleaved boost converter (MIBC) topology for improving the reliability and efficiency of power electronic systems.

Abstract

Purpose

This study aims to present a modified interleaved boost converter (MIBC) topology for improving the reliability and efficiency of power electronic systems.

Design/methodology/approach

The MIBC topology was implemented with two parallel converters, operated with a −180 degree phase shift. Using this methodology, ripples are reduced. The state-space model was analysed with a two-switch MIBC for different modes of operation. The simulation was carried out and validated using a hardware prototype.

Findings

The performance of the proposed MIBC shows better output voltage, current and power than the interleaved boost converter (IBC) for the solar PV array. The output power of the proposed converter is 1.353 times higher than that of existing converters, such as boost converter (BC) and IBC. The output power of the four-phase IBC is 30 kW, whereas that of the proposed two-phase MIBC is 40.59 kW. The efficiency of MIBC was better than that of IBC (87.01%). By incorporating interleaved techniques, the total inductor current is reduced by 29.60% compared with the existing converter.

Practical implications

The proposed MIBC can be used in a grid-connected system with an inverter circuit for DC-to-AC conversion, electric vehicle speed control, power factor correction circuit, high-efficiency converters and battery chargers.

Originality/value

The work presented in this paper is a modified version of IBC. This modified MIBC was modelled using the state-space approach. Furthermore, the state-space model of a two-phase MIBC was implemented using a Simulink model, and the same was validated using a hardware setup.

Abstract

Purpose

Because of the importance of having enough sleep in life and health, this study aims to determine the effect of vitamin D supplementation on sleep quality and pregnancy symptoms (primary outcomes) and side effects (secondary outcome).

Design/methodology/approach

In this triple-blind randomized controlled clinical trial, 88 pregnant women with gestational age of 8–10 weeks and serum vitamin D concentration less than 30 ng/ml were allocated into vitamin D (n = 44) and control (n = 44) groups by blocked randomization method. The vitamin D group received a 4,000 IU vitamin D pill, and the control group received a placebo pill daily for 18 weeks. Independent t-, Mann–Whitney U and ANCOVA tests were used to analyze the data.

Findings

The post-intervention mean (SD: standard deviation) of total sleep quality score in the vitamin D and placebo group were 1.94 (2.1) and 4.62 (1.71), respectively. According to the Mann–Whitney U test, this difference between the two groups was statistically significant (p < 0.001). The mean (SD) of pregnancy symptoms in the vitamin D and placebo groups was 23.95 (16.07) and 26.62 (13.84), respectively, and there was no significant difference between the two groups based on ANCOVA test (p = 0.56). Considerable side effects were not observed in any groups.

Originality/value

This study was conducted due to the contradictory results of the effect of vitamin D on sleep quality and the high prevalence of sleep disorders and pregnancy symptoms.

Abstract

Purpose

The purpose of this study was to examine the indirect effects of strategic leadership for learning between sales employees’ perceived learning opportunities and organizational commitment and job performance.

Design/methodology/approach

A total of 204 responses from sales employees in a South Korean company were analyzed using path analysis to test the hypothesized model and hypotheses.

Findings

Results of the analysis showed that strategic leadership has a significant indirect effect on the relationship between perceived learning opportunities and job performance and organizational commitment.

Originality/value

The results of this study challenge the belief that providing learning opportunities improves salesperson performance and organizational commitment. The results indicate that the relationship between continuous learning opportunities and performance, as well as between opportunities and organizational commitment, is statistically nonsignificant. However, the authors did find that providing continuous learning opportunities via strategic leadership because learning increases performance and organizational commitment.

Abstract

Purpose

The crude oil market plays a key role in addressing the issue of energy economics. This paper aims to detect the causality relationship between the crude oil market and economy based on the financial system.

Design/methodology/approach

This paper used the static and dynamic Hatemi-J Bootstrap Toda–Yamamoto and Diebold–Yilmaz connectedness index. The Hatemi-J Bootstrap Toda-Yamamoto approach allows researchers to use nonstationary data and that method is robust to nonnormal distribution and heteroscedasticity. The Diebold–Yilmaz connectedness index model provides researchers to detect the power of connectedness besides linkage direction. The analyzed period is the span from January 3, 2005 to October 3, 2022.

Findings

The results show bidirectional causality in the full sample but unidirectional causality before and after the 2008 financial crisis. During the 2008 financial crisis period and the COVID-19 period, there was a bidirectional and unidirectional causality, respectively. The connectedness approach indicates that the crude oil market affects financial stress through investors’ risk preferences.

Research limitations/implications

The Diebold–Yilmaz spillover index model is based on vector autoregression methods with a stationarity precondition. However, some of the five dimensions that constitute the financial stress index (FSI) are nonstationary in level. Therefore, the authors takes the first difference of the nonstationary data.

Practical implications

The linkage between the crude oil market and the FSI provides useful information for investors and policymakers. For instance, this paper indicates that an investor wanted to forecast future value of the crude oil (financial stress) should consider the current and past values of financial stress (crude oil). Moreover, policymaker should consider the crude oil market (FSI) to make a policy proposal for financial system (crude oil market).

Originality/value

Recently, indicators of economic activity levels (economic policy uncertainty, implied volatility index) have begun to be considered to analyze the relationship between energy and the economy but very little is known in the literature about the leading and lagging roles of data in subsample periods and the linkage channel. The other originality of this research is using the new econometric approaches.
