In this paper, the effects of the recent global financial crisis on efficiency and profitability of financial institutions were analyzed. In a comparative study, the impacts of the global financial crisis on the performance of Islamic and commercial banks were examined. The fundamental difference between Islamic and conventional banking is that Islamic banking is founded upon the ethical principles of Islamic tradition and law (Sharia). By utilizing a sample of eight Islamic banks and eleven commercial banks, the impact of the global financial crisis on efficiency and profitability of the banking sector was evaluated. This study covered the period from 2006 to 2013. The results of this research were obtained from the Altman Z-score model, ratio analysis, the data envelopment analysis (DEA) method, and the seemingly unrelated regression (SUR) model. The results show that during the study period, Islamic banks (IBs) managed to maintain their efficiency while most commercial banks (CBs) suffered a loss in their efficiency. Furthermore, this study found that the financial crisis did not have a significant impact on the profitability of Islamic banks.

Fish oils (FOs) have anti-inflammatory effects and lower serum triglycerides. This study examined adipose and muscle inflammatory markers after treatment of humans with FOs and measured the effects of ω-3 fatty acids on adipocytes and macrophages in vitro. Insulin-resistant, nondiabetic subjects were treated with Omega-3-Acid Ethyl Esters (4 g/day) or placebo for 12 weeks. Plasma macrophage chemoattractant protein 1 (MCP-1) levels were reduced by FO, but the levels of other cytokines were unchanged. The adipose (but not muscle) of FO-treated subjects demonstrated a decrease in macrophages, a decrease in MCP-1, and an increase in capillaries, and subjects with the most macrophages demonstrated the greatest response to treatment. Adipose and muscle ω-3 fatty acid content increased after treatment; however, there was no change in insulin sensitivity or adiponectin. In vitro, M1-polarized macrophages expressed high levels of MCP-1. The addition of ω-3 fatty acids reduced MCP-1 expression with no effect on TNF-α. In addition, ω-3 fatty acids suppressed the upregulation of adipocyte MCP-1 that occurred when adipocytes were cocultured with macrophages. Thus, FO reduced adipose macrophages, increased capillaries, and reduced MCP-1 expression in insulin-resistant humans and in macrophages and adipocytes in vitro; however, there was no measureable effect on insulin sensitivity.

Human freedom, and therefore, quality of life in many countries of the world have been restricted and diminished. Economic freedom and a controversial issue of interrelationship between economic and political freedom are empirically examined here. In several empirical estimations, embodying 155 countries of the world, some tight as well as statistically significant relationships are detected between economic freedom, on the one hand, and civil liberties, political rights, and political freedom, on the other.

One major objective of epidemiological studies into the health effects of air pollution is to establish quantitative relationships between mortality and levels of pollution in the ambient air. These studies give researchers a basis upon which to calculate the economic benefits from reduced levels of air pollution. The approach taken in this paper will follow various epidemiological studies on air pollution and mortality in the US such as Chappie and Lave, Gregor, Lave and Seskin, and Lipfert. First, the theory and methodology used in this study will be explained and contrasted with previous studies. Next, the empirical results will be presented. Finally, the meaning and usefulness of dose-response functions will be examined in terms of estimating economic benefits from pollution abatement.
