Climate change is intensifying the release and dispersion of various hazardous chemicals into marine ecosystems, such as algal biotoxins, heavy metals, persistent organic pollutants, and agricultural and industrial wastes. Eutrophication and global warming are responsible for the increase in known and emerging marine biotoxins, such as brevetoxins, palytoxins, pinnatoxins, and cyclic imines. Furthermore, tetrodotoxins and ciguatoxins, which are primarily found in tropical regions, have recently been identified in fish and bivalve molluscs from temperate areas where they had never been previously reported. These toxicants can accumulate in seafood and enter the human food chain, posing a public health concern. This review describes the interrelationship between climate change and its impact on marine organisms and human health, as well as the environment. It recommends integrating a broad range of scientific knowledge, reviewing regulatory policies, and proactively managing public health to counter these environmental threats. Full article

The 2008 financial crisis pushed policymakers around the world to rethink how banks could manage risk, leading to the implementation of stricter regulations, including capital buffers and bail-in mechanisms, aimed at making the financial system more resilient. This study examines how three key regulations under Basel III, namely, the Countercyclical Capital Buffer (CCyB), the Capital Conservation Buffer (CCB), and the Capital Surcharge (CS), shape lending patterns in Indonesian banks. The effectiveness of the bail-in policy in helping banks strengthen their capital base is also examined. This study uses difference-in-differences analysis on panel data from 97 banks between 2010 and 2024 to examine the impact of stricter capital regulations on banks’ ability to channel credit to the public and business sectors. Basel III aims to strengthen the resilience of banks; however, this policy could impact credit access and banking stability in Indonesia. This study found a positive impact on LDR of large banks after the treatment, which indicates the banks’ efforts to use the funds collected through credit distribution. This study empirically examines the impact of capital buffer regulation and the bail-in instrument in Indonesia as an emerging-market country with a segmented banking sector and banks’ classification by ownership and core capital value.

The worldwide move toward renewable energy indicates a fundamental change that is particularly important in the MENA region, which has abundant renewable resources and has depended on hydrocarbon economies. This study presents an empirical examination of key macroeconomic determinants—inflation, fiscal policy, and economic volatility—on renewable energy security in MENA countries from 2000 to 2023. Applying a Panel Autoregressive Distributed Lag (ARDL) model of 16 countries, we assess the short-run dynamic and long-run equilibrium relationships, where renewable energy security is measured using the share of renewable electricity in total generation. These results support the existence of a significant long-run cointegrating relationship. We find fiscal policy to have a positive effect on renewable energy security, while inflation and economic volatility have significant negative short- and long-term effects. The error-correction term of −0.421 signaled a relatively fast return to long-run equilibrium. We conclude that sound management of these macroeconomic variables—especially price stability and counter-cyclical fiscal policies—is an essential precondition for achieving renewable energy security in the MENA region. Our policy implications highlight the need to support stable investment inquiries led by coordinated monetary, fiscal, and energy policies aimed at creating the conditions for renewable energy security.

This study investigates the volatility dynamics of the Bahrain All Share Index (BAX) between 2010 and 2025, a period marked by COVID-19 and regional geopolitical shocks. Using ARMA (1,1) to model returns and four GARCH-family models (ARCH, GARCH, EGARCH, GJR-GARCH) to capture volatility, we provide new evidence from a bank-based frontier market that has received limited empirical attention. The results reveal that returns are stationary and exhibit volatility clustering. Among the competing models, EGARCH (1,1) provides the best fit—exhibiting the lowest AIC and SIC values and the highest log-likelihood—revealing a significant leverage effect whereby negative shocks generate stronger volatility than positive shocks. This asymmetric volatility pattern contradicts earlier findings for Bahrain but aligns with theoretical expectations for bank-based financial systems. The findings carry implications for investors in terms of portfolio risk management, derivative pricing, and asset allocation. They also have important implications for regulators and policymakers, suggesting that counter-cyclical buffers and interest rate adjustments could be applied to stabilize the market in anticipation of negative shocks. These insights enrich the scarce literature on volatility in small frontier markets and contribute to a more nuanced understanding of the volatility dynamics in the MENA region. Full article

This research determines the contribution of Corporate Social Responsibility (CSR) to reducing financial risks and, consequently, to the sustainable development of companies in different sectors of the economy and at different phases of the economic cycle (using Russia as an example). The informational and empirical base comprises data on the dynamics of stock prices of sectoral indices of the Moscow Exchange’s total return “gross” (in Russian rubles): oil and gas, electricity, telecommunications, metals and mining, finance, consumer sector (retail trade), chemicals and petrochemicals, and transportation, as well as the “Responsibility and Openness” index in 2019 (before the crises), in 2020 (COVID-19 crisis), 2022 (sanction crisis), and 2024 (Russia’s economic growth). Economic–mathematical models, compiled through regression analysis, showed that the contribution of CSR to reducing the financial risks of companies is highly differentiated among economic sectors and phases of the economic cycle. The research presents a new sectoral perspective on counter-cyclical management of the financial risks of companies through CSR, enabling a deeper study of the cause-and-effect relationships of such management for the sustainable development of companies from different economic sectors. This is the theoretical significance of this research, its novelty, and its contribution to the literature. The research has practical significance, revealing previously unknown best practices for the sustainable development of companies from different economic sectors of Russia across different phases of the economic cycle. The systematized experience will be useful for forecasting the financial risks of companies during future economic crises in Russia and improving the practice of planning and organizing the financial risk management of Russian companies through CSR. The authors’ conclusions have managerial significance because they will help enhance the flexibility and efficiency of corporate financial risk management by considering the sectoral specifics and cyclical nature of the economy when implementing CSR.

The recent global financial crisis (GFC) has put under scrutiny the sound remuneration policy and consequently the incentives design that influences risk-taking by managers in the banking industry to be a politically charged variable. In particular, this paper analyzes the new EU remuneration regulation of bank executive compensation and the role of corporate social responsibility (CSR) on this. Though all the EU efforts put into remuneration practices suggest commitment in aligning risk, performance, and compensation and aim at easing bank managers’ risk appetite for variable payments, the new regulation might drive unintended consequences, creating adverse selection problems in EU banks and hidden compensation habits that lower transparency, thus threatening financial system’s sustainability. Focusing on European Banking Authority (EBA) reports spanning from 2010 to 2017, the data reveals increasing values on the fixed component, less involvement in bank discipline by economic agents, and a potential for accounting-based incentives compensation that might reinforce attitudes towards building countercyclical buffers and smoothing earnings. As well, the new regulation might reduce the number of best-performing bank managers in the Eurozone, since “bad risks” are accepted to the detriment of “good risks,” which might stimulate their migration. In contrast, CSR investment is supposed to offset such practices and incentives that harm EU financial stability. As a result, policymakers, banks, and regulators should promote the transparency of CSR disclosure. Full article

Ischemic stroke is one of the most disabling diseases and a leading cause of death globally. Despite advances in medical care, the global burden of stroke continues to grow, as no effective treatments to limit or reverse ischemic injury to the brain are available. However, recent preclinical findings have revealed the potential role of transient receptor potential cation 6 (TRPC6) channels as endogenous protectors of neuronal tissue. Activating TRPC6 in various cerebral ischemia models has been found to prevent neuronal death, whereas blocking TRPC6 enhances sensitivity to ischemia. Evidence has shown that Ca²⁺ influx through TRPC6 activates the cAMP (adenosine 3’,5’-cyclic monophosphate) response element-binding protein (CREB), an important transcription factor linked to neuronal survival. Additionally, TRPC6 activation may counter excitotoxic damage resulting from glutamate release by attenuating the activity of N-methyl-d-aspartate (NMDA) receptors of neurons by posttranslational means. Unresolved though, are the roles of TRPC6 channels in non-neuronal cells, such as astrocytes and endothelial cells. Moreover, TRPC6 channels may have detrimental effects on the blood–brain barrier, although their exact role in neurovascular coupling requires further investigation. This review discusses evidence-based cell-specific aspects of TRPC6 in the brain to assess the potential targets for ischemic stroke management. Full article

We used a time-series cross-section dataset to test several hypotheses pertaining to the role of macroprudential policy instruments in the management of the financial cycle in advanced open economies. The short-run effects are most significant for caps on loan to value and income (LTV and LTI) and risk weights (RW). The long-run coefficients of credit growth with respect to the indicators of amortisation requirements (Amort) and RW are also significant. The estimation results when house price growth is the dependent variable are consistent with these results. Our findings do not support that Basel III type countercyclical buffer (CCyB) has affected credit growth, and we suggest that the variable is mainly a control in our dataset. In that interpretation, it is interesting that the estimated coefficients of the other instruments are robust with respect to exclusion of CCyB from the empirical models. The main results are also robust to controls in the form of impulse indicator saturation (IIS), which we employed as a novel estimation method for macro panels. Full article
