Does currency smirk predict foreign exchange return?
This paper finds the predictive power of currency smirk to forecast foreign exchange (FX) return to be convincing. Although the steeper currency smirk appears in the middle of the trading day, the conclusive currency smirks' predictability lasts over the next trading day, as the FX market is highly adept at incorporating the information embedded in the currency smirk. The implication of these fmdings is that the currency smirk is distinctive for forecasting very short-term FX fluctuations, and that day- or overnight FX traders can apply its uniqueness to profit from quick price swings in the 24-hour globalFX market
Loan loss reserves and bank stock returns: Evidence from Asian banks
This study examines the effects of the loan-loss-reserves-to-gross-loans ratio, a proxy for credit risk, on bank stock returns for a sample of 42 listed Asian banks during the period 1999-2007. By applying a panel data analysis that includes a control for market returns, book-to-market ratio, size, and country-specific factors, the results show that the ratio has a negative and significant influence on bank stock returns. Overall, the results suggest that credit risk remains a major threat to Asian banks. In addition, while loan loss reserves are needed for mitigating credit risk, investors do not consider them as good news or a credible signal concerning bank intentions to resolve problem loans
Loan loss provisions and lending behaviour of banks: Asian evidence during 1992-2009
Effects of loan loss provisioning on lending behaviour of banks remain a major concern in policy circles in order to strengthen both bank stability and financial intermediation. A sample of 686 commercial banks in Asian countries over the 1992 - 2009 period is used to identify factors contributing to the occurrence of a procyclical effect of loan loss provisions on loan growth. Our empirical results highlight that non-discretionary provisions have a procyclical effect, as higher non-discretionary provisions reduce loan growth of banks. This procyclical effect holds for large banks but not small banks. A closer investigation shows that bank market structure, economic development and institutional quality also affect the link between non-discretionary provisions and loan growth of banks. More specifically, higher bank competition, higher per capita income and higher rule of law mitigate the procyclical effect of non-discretionary provisions on loan growth regardless of whether banks are large or small. These findings have policy implications concerning the adoption of the dynamic provisioning system for Asian banks
Sepsis and nosocomial infections: The role of medico-legal experts in Italy
Sepsis is a leading cause of morbidity and mortality worldwide. It is defined as the presence of a Systemic Inflammatory Response Syndrome, and it represents a significant burden for the healthcare system. This is particularly true when it is diagnosed in the setting of nosocomial infections, which are usually a matter of concern with regard to medical liability being correlated with increasing economic costs and peopleâs loss of trust in healthcare. Hence, the Italian governance promotes the clinical risk management with the aim of improving the quality and safety of healthcare services. In this context, the role of medico-legal experts working in a hospital setting is fundamental for performing autopsy to diagnose sepsis and link it with possible nosocomial infections. On the other hand, medico-legal experts are party to the clinical risk management assessment, and deal with malpractice cases and therefore contribute to formulating clinical guidelines and procedures for improving patient safety and healthcare providersâ work practices. Due to this scenario, the authors here discuss the role of medico-legal experts in Italy, focusing on sepsis and nosocomial infections

Linear Sigma EFT for Nearly Conformal Gauge Theories
We construct a generalized linear sigma model as an effective field theory
(EFT) to describe nearly conformal gauge theories at low energies. The work is
motivated by recent lattice studies of gauge theories near the conformal
window, which have shown that the lightest flavor-singlet scalar state in the
spectrum () can be much lighter than the vector state () and
nearly degenerate with the PNGBs () over a large range of quark masses.
The EFT incorporates this feature. We highlight the crucial role played by the
terms in the potential that explicitly break chiral symmetry. The explicit
breaking can be large enough so that a limited set of additional terms in the
potential can no longer be neglected, with the EFT still weakly coupled in this
new range. The additional terms contribute importantly to the scalar and pion
masses. In particular, they relax the inequality , allowing for consistency with current lattice data.Comment: 9 pages, 1 figure, published versio

Home-Based Exercise in Elderly Patients with Claudication and Chronic Kidney Disease Is Associated with Lower Progressive Renal Function Worsening: A 5-Year Retrospective Study
This observational study aimed to monitor the 5-year trends of kidney function in patients with peripheral artery disease (PAD) and concomitant chronic kidney disease (CKD) enrolled or not enrolled into a rehabilitative exercise program. Sixty-six patients (aged 72 ± 10, males n = 52) at KDOQI stages III-IV and PAD at Rutherfordâs stage I-III were included in the study, with a group (Exercise, EX; n = 32) receiving a 6-month structured pain-free home-based walking program and a group (Control, CO; n = 34) receiving walking advice and optimal nephrological care. Outcomes included kidney function measured through serum creatinine (sCr) and clinical outcomes, including the rate of advance of CKD stages and admission to dialysis, revascularizations, and hospitalizations. At baseline, the two groups were comparable for age, nephropathy, medications, comorbidities, and PAD severity. Patients in the EX group safely completed the exercise program. SCr values were slightly increased in EX (baseline: 2.35 ± 0.32; 5-year: 2.71 ± 0.39 mg/dL) and progressively worsened in CO (baseline: 2.30 ± 0.31; 5-year 4.22 ± 0.42 mg/dL), with a significant between-group difference (p = 0.002). The control group also showed a higher number of dialysis admissions (5 vs. 0, p = 0.025) and advancing CKD stage as well a higher risks for lower limb revascularization (hazard ratio: 2.59; 95%CI: 1.11â6.02; p = 0.027) and for all-cause hospitalization (hazard ratio: 1.77; 95%CI: 1.05â2.97; p = 0.031). PAD-CKD patients enrolled in a low-moderate intensity home-exercise program showed more favorable long-term trends in kidney function and clinical outcomes than patients with usual care. These preliminary observations need to be confirmed in randomized trials
