In this study, we investigated the effect of transcranial alternating current stimulation (tACS) on voluntary risky decision making and executive control in humans. Stimulation was delivered online at 5 Hz (θ), 10 Hz (α), 20 Hz (β), and 40 Hz (γ) on the left and right frontal area while participants performed a modified risky decision-making task. This task allowed participants to voluntarily s...

background: intravenous drug users (ivdus) who share needles/syringes and practice sexual behaviors, are the most important group in the transmission of blood-borne infection diseases such as hepatitis c virus (hcv). therefore identification of prevalent high-risky behaviors among ivdus to detect the most route of transmission among them is essential to develop harm reduction programs among ivd...

conclusions our findings suggest the importance of high-risk behaviors in terms of etiological pathways, maintenance process and treatment interventions. results the results suggested that the model had good fit (root mean square of approximation = 0.07, comparative fit index = 0.95, normed fit index = 0.91, goodness of fit index =0.93) with the data. accordingly, the indirect effect of resilie...

In a continuous-time economy, we investigate the asset allocation problem among a risk-free asset and two risky assets with an ambiguous correlation between the two risky assets. The portfolio selection that is robust to the uncertain correlation is formulated as the utility maximization problem over the worst-case scenario with respect to the possible choice of correlation. Thus, it becomes a ...

PURPOSE While there is research indicating that many factors influence the young novice driver's increased risk of road crash injury during the earliest stages of their independent driving, there is a need to further understand the relationship between the perceived risky driving behaviour of parents and friends and the risky behaviour of drivers with a Provisional (intermediate) licence. MET...
