Abstract
Purpose
Dietary patterns have been used to explore the association between dietary factors and risk of pancreatic cancer (PC) and renal cancer (RC); however, the association remains unclear. The purpose of this paper is to comprehensively review these associations.
Design/methodology/approach
Pertinent studies published prior to March 2016 were systematically searched and retrieved through PubMed and Scopus databases. Adjusted risk estimates were derived by comparing the highest with the lowest categories of dietary pattern scores and were combined by using the fixed-effects model when no substantial heterogeneity was observed; otherwise, the random-effects model was used.
Findings
A total of nine studies, five for PC (including 2,059 cases and 41,774 participants/controls) and four for RC (with 1,327 cases and 53,007 participants/controls), were included in this meta-analysis. A decreased risk of PC was shown for the highest compared with the lowest categories of the healthy dietary pattern (OR = 0.72, 95 per cent CI = 0.51-0.94, random effects (p-value for heterogeneity = 0.004)), whereas no significant association with Western dietary was observed (OR = 1.16, 95 per cent CI = 0.87-1.44, fixed effects). In the overall analysis, a significant association was found between the healthy dietary pattern and reduced risk of RC (OR = 0.59, 95 per cent CI = 0.48-0.71, fixed effects (p-value for heterogeneity = 0.459)), whereas the Western pattern was positively associated with risk of RC (OR = 1.42, 95 per cent CI = 1.14-1.69, fixed effects). For both cancers, the reduced risk associated with the healthy pattern was restricted to case-control, but not cohort, studies. Furthermore, drinking pattern was significantly related to reduced risk of RC (OR = 0.68, 95 per cent CI = 0.42-0.94).
Originality/value
To the authors’ knowledge, the present study is the first English document to summarize systematically the findings from observational studies in response to this question whether a posteriori dietary patterns are associated with susceptibility to the risk of renal and ovarian cancers.

This study aims to develop a price policy for fossil fuel consumption, as it is an effective instrument to manage the demand-side of energy economics.
Abstract
Purpose
This study aims to develop a price policy for fossil fuel consumption, as it is an effective instrument to manage the demand-side of energy economics.
Design/methodology/approach
This research estimates the demand elasticities of diesel, gasoline, fuel oil and kerosene by using static, dynamic and error-correction models in log-linear form.
Findings
The findings show that fossil fuel demand responds to price changes less than income changes, as fuel price is inelastic, but income is elastic. In that respect, the impact of price change decreases constantly with increasing energy price, followed by subsidy reform. Subsidy removal and price policy reformation is the UN recommendation for subsidizing countries, including Iran, to reduce fossil fuel consumption, whose intensity depends on the price elasticities.
Practical implications
As a result of this price policy, diesel, gasoline and liquefied petroleum gas prices should increase at least 1.8%–7.3%, 4.4%–6.4% and 7%–8.6%, respectively, and gradually within 2018–2030. The price policy improves all the pillars of sustainable development, including economy, environment and social (health). Overall, such a target can potentially save 3%–29% of diesel, 34%–56% of gasoline and 15%–20% of liquefied petroleum gas, as well as reduce 15%–40% of CO2 emissions annually, and can save potentially more than 510,000 lives annually. Thus, the energy price policy can fundamentally improve sustainability.
Originality/value
The estimated elasticities outline the required prices to decrease the fossil fuels, according to the UN mitigation targets, as price policy recommendation.

Abstract
Purpose
Content analysis was used to measure corporate social responsibility (CSR) reporting. The ordinary least squares (OLS) regressions with robust standard errors are used to examine the relationships for a sample of 168 firm-year observations listed on the Palestine Exchange during 2018–2021. A logistic regression is also utilized as an alternative measurement for CSR quantity disclosure and to ensure the robustness of the author’s main findings.
Design/methodology/approach
Based on 168 observations listed on the Palestine Exchange (PEX) between 2018 and 2021, this study examines the impact of women's representation on the CSR reporting of Palestinian firms' boards. Moreover, the moderating effect of ownership concentration on the relationship between BGD and CSR reporting is examined. In order to test the hypotheses, the author’s employ OLS regressions with robust standard errors. A logistic regression is also utilized as an alternative measurement for CSR quantity disclosure and to ensure the robustness of the author’s main findings.
Findings
The results reveal that Palestinian companies with more women on their boards have higher CSR practices and disclosure levels. In addition to the validity of agency, stakeholder and legitimacy theories, the findings show the relevance of gender socialization and critical mass theories in explaining the favorable influence of women's presentation on boards in promoting best practices among Palestinian firms, such as CSR disclosure.
Research limitations/implications
The study contributes to the limited literature in the MENA and Arab region countries by examining the influence of BGD on CSR reporting in Palestine, an emerging economy characterized by highly political and economic instability. The study offers a novel contribution by examining the impact of BGD, on not only the CSR reporting quantity but also the reporting quality. However, the generalizability of the study is limited due to the small sample size.
Practical implications
The findings of the study may bring the issues of CSR disclosure and female representation on board of directors to the attention of Palestinian firms' board of directors and managers, investors, professional associations, policymakers and regulators. While listed firms are only required to provide general information that falls under the scope of CSR in their annual reports under the Palestinian code of corporate governance, women representation on boards of directors is not addressed.
Originality/value
This study adds to the very limited literature on the role of the BGD in promoting CSR reporting in the Middle Eastern and Arabic markets in general, and in the Palestinian context in particular. This paper not only investigates but also seeks to theorize this role.

Abstract
Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.
