There are so many studies which evaluated the maternal quality of life based on their delivery type with different results. The purpose of this paper is to evaluate the effect of type of delivery on the maternal QOL systematically.

In this systematic review, which was conducted for 15 years (2000-2016), the international databases including PubMed, Scopes and ISI and the Persian databases were searched using the following words: quality of life or health-related quality of life, vaginal delivery, cesarean delivery or cesarean section. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was adopted for this study. The quality of articles was assessed by a checklist that has been used in previous studies. All of the data analysis was performed using STATA ver.12.

In total, 13 articles were included in the present systematic review and meta-analysis. The overall sample included 8,136 women (3,990 cesareans vs 4,146 vaginal). The results of the random effect model for eight QOL dimensions based on SF-36 questionnaire showed that there was no significant difference between two groups in terms of QOL. But this model for four QOL dimensions of WHOQOL showed that the maternal in two groups had a significant difference in two dimensions of QOL (mental health and total health) and insignificant difference in other dimensions.

The results of the study may have been affected by the selection of few databases. Therefore, researchers are encouraged to test the proposed propositions in further databases.

The study results could be helpful to design appropriate policies for maternal based on their type of delivery.

This systematic review showed that despite the insignificant difference between women with vaginal delivery vs women with cesarean delivery in some aspects of QOL, it can be concluded that health status of women with vaginal delivery is better than women with cesarean delivery, so it should be considered in the setting of appropriate policies and implementation framework to encourage women for choosing the appropriate delivery type.

The purpose of this paper (systematic review and meta-analysis) is to synthesize and analyze studies that assessed Iranian hospital efficiency.

A systematic literature search was conducted using both international (the Institute for Scientific Information, Scopus and PubMed) and Iranian scientific (Magiran, IranMedex and Scientific Information Database) databases. The review included original studies that used the Pabon Lasso Model to examine Iranian hospital performance, published in Persian or English. A self-administered checklist was used to collect data. In total, 12 questions were used for quality assessment.

In total, 34 studies met our inclusion criteria. The fixed-effects meta-analysis indicated that 19.2 percent (95% confidence interval (CI): 15.6–23.2 percent) of hospitals were in Zone 1 (poor performance: low bed turnover rate (BTR) and bed occupancy rate (BOR) and high average hospital stay (ALoS)), 23.7 percent (95% CI: 20.1–27.8 percent) were in Zone 2, 31.7 percent (95% CI: 27.7–36 percent) in Zone 3 (good performance: high BTR and BOR and low ALoS) and 25.4 percent (95% CI: 21.7–29.5 percent) in Zone 4.

Results help Iranian health policymakers to understand hospital performance, which, in turn, may lead to promoting greater awareness and policy attention to improve Iranian hospital efficiency.

This study indicated that most Iranian hospitals had sub-optimal performance. Further studies are required to understand factors that explain the country’s hospital inefficiency.

The purpose of this study is to investigate the determinants and the intention to use information technology (IT) audit technologies.

The research model explores the external and internal factors that influence IT audit usage in Saudi Arabia. The external factors include IT audit education, professional support provided by professional accounting and auditing bodies, external pressure and social factors. The internal factors include the firm’s organizational support, complexity of accounting information systems, IT audit competency, adoption risk, ease of use and readiness. These factors affect the intention to use IT audits, represented by the perceived benefits and intention to use IT audits, which in turn affect IT audit usage. The study uses structural equation modelling to estimate a sample size of 261 respondents.

The findings suggest that internal factors significantly influence both IT audit usage and intention to use IT audits. However, the external factors exhibit insignificant associations with IT audit usage. The findings also indicate that IT auditors in Saudi Arabia heavily rely on Microsoft Excel, Microsoft Word and email/Outlook as essential IT audit tools. However, the findings reveal that there is still a role for specialized IT audit tools such as generalized audit software and Audit Command Language but this usage is marginal.

The present study provides significant insights for auditors, companies’ boards, professional bodies and policymakers to enhance the development and usage of IT audits. The study revealed the absence of supportive external factors that policymakers and professional bodies should exercise in this regard. The findings also indicate that IT audit education and capacity programmes are required to promote competency and adoption of IT audit technologies.

The study contributes to IT auditing by identifying significant factors influencing IT audit adoption. It underlines the relevance of internal and external determinants and perceived benefits as drivers of IT audit adoption. The current study provides an original piece of research that highlights a comprehensive investigation of the determinates of IT audit usage in a developing country that is shifting towards artificial intelligence and IT advancements.

This paper aims to explore the mechanism of the slip phenomenon at macro/micro scales, and analyze the effect of slip on fluid flow and heat transfer, to reduce drag and enhance heat transfer.

The improved tangential momentum accommodation coefficient scheme incorporated with Navier’s slip model is introduced to the discrete unified gas kinetic scheme as a slip boundary condition. Numerical tests are simulated using the D2Q9 model with a code written in C++.

Velocity contour with slip at high Re is similar to that without slip at low Re. For flow around a square cylinder, the drag is reduced effectively and the vortex shedding frequency is reduced. For flow around a delta wing, drag is reduced and lift is increased significantly. For Cu/water nanofluid in a channel with surface mounted blocks, drag can be reduced greatly by slip and the highest value of drag reduction (DR) (67.63%) can be obtained. The highest value of the increase in averaged Nu (11.78%) is obtained by slip at Re = 40 with volume fraction φ=0.01, which shows that super-hydrophobic surface can enhance heat transfer by slip.

The present study introduces and proposes an effective and superior method for the numerical simulation of fluid/nanofluid slip flow, which has active guidance meaning and applied value to the engineering practice of DR, heat transfer, flow control and performance improvement.

Coronavirus Disease 2019 (COVID-19) pandemic has affected many different aspects of people’s lives around the world, including household food security. This study aims to investigate the food security status and its determinants, with emphasis on perceived social support among the Iranian population during the epidemic..

This cross-sectional study was conducted among 2,871 Iranian adults by social media in all provinces of the country. Demographic and socioeconomic information, household food security status and perceived social support status were assessed by the validated questionnaires. Data was analyzed by statistical package for the social sciences version 22.0, with one-way ANOVA, Chi-square and multinomial logistic regression tests.

The prevalence of food security among the studied population was 55.2%. The results indicated that perceived social support plays a protective role on food security [odds ratio (OR) = 1.07, confidence interval (CI) = 1.06, 1.09, P-value < 0.001]. Reduced income during the epidemic [OR = 0.29, CI = 0.17, 0.47, P-value < 0.001] and presence of an old person (>65 years old) in the household [OR = 1.72, CI = 1.14, 2.60, P-value < 0.05], were significantly higher among moderate to severe food insecure group than food-secure group. More monthly income [OR = 0.28, CI = 0.13, 0.57, P-value < 0.001] and homeownership [OR = 1.83, CI = 1.22, 2.75, P-value < 0.05] were also predictors of food security status.

The development of supportive strategies which act immediately can protect vulnerable people against the consequences of the epidemic, including food insecurity. Long-term planning should also be considered to improve society’s resistance against such disasters.

Most available studies focus mainly on Islamic economics and finance with none conducted on Islamic marketing bibliometrics. The purpose of this paper is to commemorate the 11th anniversary of the Journal of Islamic Marketing (JIMA) in 2020 by evaluating the publication pattern and scientific advancement of JIMA between 2010 and 2020.

The paper used bibliometric analysis and visualization of similarities viewer software for the graphical conception of the bibliographic data, including bibliographic coupling, co-citation and co-occurrence of keywords.

There was an increase in the number of journal documents and this depicts a rising interest in the submission of articles. Moreover, the number of conceptual papers received has also increased and this shows JIMA’s support for knowledge development in Islamic marketing. Meanwhile, Halal is one of the currently trending topics, therefore, there is an opportunity for more exploration and research on the concept.

The bibliographical material applied in this study was only retrieved from the Scopus database. Therefore, more studies need to be conducted by incorporating other indexing and database in the scientific field of Islamic marketing.

The research is useful to understand queries related to scientific products such as the number of publications, contributors, keywords, countries and institutions often used in the articles of the journal.

It presented an exclusive bibliometrics analysis and identified the main trend of the publications in the journal from 2010 when it was established until the second issue of volume 11 in 2020.
