This research is motivated by the development of dialogue and debate regarding company reporting in the form of sustainability reporting (SR) – which is separate from the annual report (AR) – or integrated reporting (IR). Research into SR and IR is still fascinating, and this study addresses the debate about them. This study aims to examine which of the two reports is more valuable for investors, and also examine whether IR has value relevance because the information in the IR could reinforce the importance of the accounting information.

As with previous studies, we adopted a valuation approach – the Ohlson model – to assess the value relevance of non-financial information (in the form of SR/IR) and financial information. As a preliminary study, we used non-financial information as a binary variable, i.e. a group of companies that issue sustainability reports and a group of companies that issue integrated reports. Therefore, they complement and interact with the financial statements’ information. This paper used panel data consisting of 931 firm-years of SR issuers and 922 firm-years of IR issuers in Europe and Africa in the period from 2005 to 2019.

The results showed that SR had a higher value relevance than IR. However, when the authors interact the corporate reporting form with the accounting information, IR had value relevance because the information contained in the IR could reinforce the importance of the accounting information.

This study will support regulators in various countries to monitor the reporting practices of companies in those countries. The results of this study provide evidence that sustainability reports get a higher response than integrated reports. However, when interacted with the accounting variables, information in the IR is considered to be more relevant than that found in the SR. Therefore, it is hoped that the results of this study will help the International Integrated Reporting Council (IIRC) in reviewing IR practices around the world so that the implementation of IR practices can be realized in accordance with the mission that the IIRC wants to achieve.

Research into the value relevance of SR and IR has been carried out by several previous researchers separately, but to the best of the author’s knowledge, there are no studies comparing the value relevance of the two.

This paper aims to conduct a systematic review of the literature on the quality of integrated reports (IR) and highlight the gaps in the existing research to provide directions and suggestions for future research.

This study was conducted through a systematic literature review using content analysis based on 40 papers from the Scopus, Web of Science and EBSCOhost databases on IR quality. While reading the full-text papers, the authors found six additional papers referenced by the literature being reviewed that were relevant to IR quality. Thus, there were 46 papers in the final review. The analysis begins with the definition and dimension of IR quality and theoretical lenses. Furthermore, this study outlines constructs or variables used in the previous literature.

The authors found that most studies used the quantitative method (41 papers or 89%). Five papers in the literature used qualitative methods (11%). Most researchers (34 papers or 72%) defined IR quality as consistent with the International Integrated Reporting Council framework, specifically the eight content elements. In particular, with the constructs that make up the quality of the IR, variations between researchers were found. Furthermore, there were some gaps that could be the directions for future research.

The literature that provides academic knowledge about IR quality is still limited, and research on IR is still growing. The literature review conducted by this study can provide an overview of the current research positions on the quality of IR and directions for future research in this area.

This study intends to show corporate executives a framework demonstrating the quality of corporate reporting. It can impact not only investors as a specific stakeholder group but also other stakeholder groups.

To the best of the authors’ knowledge, this study is the first literature review to examine the quality of IR, thus providing a map of current research to suggest directions for future research. Most of the previous literature reviews have been focused on integrated reporting (IR) in general and not quality.

The purpose of this study is to examine the relationship between corporate governance and risk management of Indonesian banks.

Implementation of good corporate governance is measured by good corporate governance composite rating, which is the result of bank's self-assessment. Bank risk managements are measured by market risk, credit risk, liquidity risk and operational risk.

The study results showed that good corporate governance implementation in Indonesia was able to influence bank risk. There were differences in credit risk, liquidity risk and operational risk in banks with different governance ratings, but not at market risk.

The effectiveness of risk management and good corporate governance implementation is needed to enable banks to identify problems early, to follow up on rapid improvements and to be more resilient to crises. This study is an analysis of the relationship between corporate governance and banks' risk management in Indonesia. In particular, risk management is measured by four risks: market risk, credit risk, liquidity risk and operation risk.

This paper aims to study the effect of green lemon zest combined with sardine proteins in diabetic hypertensive rats (DHRs).

Male Wistar rats (n = 30) weighing 250 ± 10 g were divided into five groups. The first group consumed a diet containing 20 per cent casein (C). The other four groups are rendered diabetic by intraperitoneal injection of streptozotocin (40 mg/kg body weight), then hypertensive by subcutaneous implantation controlled time-release pellet containing ouabain (0.25 mg/pellet). One untreated group (DHR) consumed 20 per cent casein and the three other groups consumed the same diet supplemented with 2 per cent green lemon zest (DHR-lz), or with 20 per cent of sardine protein (group DHR-sp) or with the combination of both sardine proteins and green lemon zest (group DHR-sp + lz).

DHRs feeding on the combination of both sardine protein (sp) and lemon zest (lz) induced a significant decrease of diastolic blood pressure and heart rates values compared with DHR (p < 0.05). The HDLC values were increased by +55 per cent in DHR-sp + lz compared with DHR group. Moreover, plasma non-HDLC concentrations were decreased significantly compared to DHR, DHR-lz, DHR-sp and C groups. In DHR-sp + lzvs DHR group, TBARS values were decreased by −25 per cent in the liver. Moreover, kidney TBARS were significantly reduced by −66, −51, −65 and −67 per cent compared with C, DHR, DHR-lz and DHR-sp, respectively.

These results suggest that consumption of green lemon zest combined with sardine proteins can reduce blood pressure and tissue oxidative damage and, therefore, help to prevent cardiovascular complications in hypertensive diabetic patients.

The aim of this paper has twofold: (1) to explain and compare the financial evolution of Islamic and conventional banking sector in the Gulf Cooperative Council (GCC) countries before and during the COVID-19 pandemic and (2) to explore the key success factors that might affect Islamic and conventional banks performance before and mainly during COVID-19 pandemic period.

Orbis Bank Focus database and annual financial reports are used to collect financial information of Islamic and conventional banks in GCC countries over four years: 2017, 2018, 2019 and 2020. Descriptive statistics, T-test, multiple regression, and 2SLS and GMM models are employed to analyze the financial structure and performance of Islamic and conventional banks before and during the COVID-19 pandemic period.

Results of this study reveal that (1) there is a significant difference between Islamic banks and conventional banks during the crisis of COVID-19, where the conventional banks have presented a higher level of financial performance and financial liquidity than their Islamic counterparts, (2) conventional banks have revealed higher capacity to manage their financial risk during the crisis period, and (3) a high level of non-performing loan, high inflation rate and high percentage of non-important cost have a negative impact on the financial performance of Islamic banks mainly during the pandemic period of COVID-19. However, the result indicates that a high level of liquidity risk increased the performance of Islamic banks but this impact falls sharply during the pandemic period.

This study provides information that supports investors, regulators and executive managers in GCC countries. A well-structured balance sheet would improve the financial performance and risk management of the banking sector in GCC countries, especially in times of crisis and pandemics.
