Abstract
Purpose
The purpose of this study is to investigate the relationship between dietary total antioxidant capacity (DTAC) and the dietary inflammatory index (DII) with inflammatory status in children recently diagnosed with Acute Lymphoblastic Leukemia (ALL). As the relationship between diet quality scores and inflammation remains uncertain in this population, the authors carried out a hospital-based cross-sectional study.
Design/methodology/approach
The study used a cross-sectional design involving 54 children recently diagnosed with ALL. Dietary data was collected using a 147-item semi-quantitative food frequency questionnaire developed for the Tehran Lipid and Glucose Study. Inflammatory status was evaluated using various indicators like C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Glasgow prognostic score (GPS) and Complete blood count-based inflammatory score.
Findings
The authors found no significant relationship between DII with inflammatory indices and length of hospitalization in patients. However, a significant inverse relationship was observed between the antioxidant indices ferric-reducing ability of plasma, total reactive antioxidant potential and Trolox equivalent antioxidant capacity with the inflammatory index MLR, respectively (ß: −0.19, p = 0.001), (ß: −0.42, p = 0.02), (ß: −0.53, p = 0.005). Also, a significant inverse relationship between FRAP and CRP was observed in the crude model (ß: −0.13, p = 0.05). FRAP was also inversely correlated with GPS and PLR, respectively (ß: −0.08, p = 0.02), (ß: −0.26, p = 0.03). No additional significant links were discovered between food scores and the outcomes studied.
Originality/value
This study found no link between DII with inflammatory markers or hospitalization duration in children with ALL. However, the authors did observe a noteworthy inverse relationship between DTAC and certain inflammatory markers like MLR. To achieve more dependable findings, further research in this area is necessary.

Abstract
Purpose
The aim of the paper is to explore and test gender differences in the authorship of Iranian journal articles.
Design/methodology/approach
A list of articles published by Iranian authors in ISI journals in 2003 was obtained from the Web of Science. The names of authors were searched in a specific database as well as the web to find their first names and hence their gender. The articles were then broken down by gender and subject category. International collaborations of the authors were also investigated.
Findings
The productivity of female authors at the individual level as measured by article per author share was lower than male authors. In total, females accounted for 6 per cent and males for 94 per cent of the articles published in 2003. A chi‐square test showed that female contribution was significantly lower than expected.
Originality/value
The study is the first to investigate gender participation in scientific productivity in Iran and most likely in a Muslim country. The article highlights the need for qualitative studies on the gender aspect of scientific productivity in Muslim countries.

Abstract
Purpose
This research paper aims to investigate the internationalization and visibility of Iranian scientific journals covered by the Institute for Scientific Information (ISI) between 2000 and 2006.
Design/methodology/approach
A total of 1,298 articles published in seven Iranian ISI journals and a random sample of 1,298 articles written by Iranians and published in non‐Iranian ISI journals between 2000 and 2006 were selected. Impact factor (IF), total citation (TC), citation rates, self‐citation, foreign citation, international citation (IC), international authorship, and subject distribution were analyzes for the collections.
Findings
Results indicated that: the visibility rate of Iranian journals is low compared to their international counterparts; the international visibility of Iranian journals differs among disciplines; the increasing citation rate is less than the increase in publication rate; and the majority of authors who published in these journals were Iranian.
Originality/value
Mere inclusion of scientific journals in the ISI does not necessarily lead to an increase in international visibility. The study highlights the need for more studies on the techniques to increase the visibility of scientific journals of the developing countries.

Abstract
Purpose
This study aims to apply some concepts of actuarial statistics to the authorship of Iranian ISI papers in the field of chemistry based on Price’s model. The study determines scientific birth rate, death rate, infant mortality rate, natural increase rate and life expectancy.
Design/methodology/approach
Price maintained that authors in each given period in any field fall into four categories including newcomers, transients, continuants and terminators. He suggested that actuarial statistics could be applied to authorship to calculate death rate and birth rate in scientific fields. A total 25,573 papers written by 59,661 Iranian chemistry authors between 1973 and 2012 were downloaded from Web of Science (WoS) and were subjected to statistical analysis.
Findings
The average birth rate was 66.7 per cent, the average death rate was 19.4 per cent, infant mortality rate was 51.2 per cent, average natural increase was 47.3 per cent, the average life expectancy was 1.98 years and the longest scientific age was 22 years. The results show that although a large number of people start their scientific activity, the number of those who terminate their activity in the same year as they start (infant mortality rate) is also large and little continuity exists in the publishing activities of Iranian chemists.
Research limitations/implications
The findings have implications for the planning of human resources in science. They could help maintain a stable scientific labor force and decide for instance whether a larger number of scientists should be trained and hired, or the barriers should be removed so the existing scientists can work for more years. The limitation is that the study is restricted to ISI articles, although they are not the only kind of scientific output.
Originality/value
This is the first study of its kind on Iranian scientific output. It shows that the overall labor force in the field of chemistry in Iran was not satisfactory, as the majority of authors in each period are transients. There is a need for better planning for the labor force.

Abstract
Purpose
This study aims to investigate the relationship between corporate governance characteristics and the financial performance of both Islamic and conventional banks in the context of an emerging market, i.e. Malaysia.
Design/methodology/approach
This study includes 300 bank-year observations from Islamic and conventional banks over the period 2010–2021. The dynamic panel model (generalized method of moments [GMM]) was considered the primary estimation model that solves simultaneity, endogeneity and omitted variable problems as most governance variables are endogenous by nature. Hence, static models are considered biased after conducting the DWH test of endogeneity, and considering dynamic panel GMM is valid proven by Sargan and Hensen and first-order (ARI) and second-order (ARII) tests.
Findings
Based on the regression results, the authors discovered that board size, female participation in the board and director remuneration have a significant positive impact on bank performance, whereas board meetings have a significant negative impact. Furthermore, the board governance structure of commercial banks is found to be more passive than that of Islamic banks.
Practical implications
The study’s findings added a new dimension to governance research, which could be a valuable source of knowledge for policymakers, investors and regulators looking to improve existing governance mechanisms for better performance of conventional and Islamic banks.
Originality/value
The goal of this study is to add to the existing literature by focusing on the impact of female board participation and other board governance mechanisms in both conventional and Islamic banks on bank performance.
