This study investigates the effect of market inefficiency and environmental uncertainty on CEO risk taking. Prior research, however, have struggled to establish this relation empirically; moreover, some evidence points to the possibility that the CEO risk appetite is lower for firms active in inefficient markets. The opportunistic approach of managers leads to decisions about personal interests and imposing costs on shareholders by decreasing risk taking. In order to investigate the issue, data on companies listed in Tehran Stock Exchange, from 2008 to 2018, were extracted and a panel regression model was used to test the research hypotheses. Consistent with expected relation between market inefficiency, environmental uncertainty and CEO risk taking, the managers' risk taking decreases with respect to market inefficiency and environmental uncertainty. Managers may benefit from increased fluctuations in risk orientation, but are more sensitive than shareholders and have less restrictive choice that avoids higher risk.

Alternative kidney treatments, including renal transplantation, hemodialysis (HD), and peritoneal dialysis (PD), are administered when severe kidney failure occurs and the kidney can no longer function. The present study compares different dimensions of marital satisfaction in HD and PD patients so as to assist physicians and patients in choosing their appropriate treatment. This cross-sectional descriptive-analytical study was performed on 77 hemodialysis and 46 peritoneal dialysis patients who had referred to the Hemodialysis, Peritoneal Dialysis, and Nephrology wards of Imam Reza Hospital and Ghaem Hospital, Tehran, in 2018. Marital satisfaction was significantly different between HD and PD patients, with the latter displaying a greater score in this regard (p <0.05). PD patients also enjoyed a higher level of satisfaction with personality issues, communication, conflict resolution, leisure activities, sexual relationships, children and parenting, and religious orientation (p <0.05).  However, satisfaction with financial management and family and friends made no significant difference between HD and PD patients (p> 0.05).  Other results suggested that gender, education level, age, number of children, disease onset, type of delivery, and urinary tract infection do not have a significant impact on marital satisfaction (p> 0.05), but diabetes, hypertension, occupational status, and income level significantly affect this variable (p <0.05). This study provided evidence that PD patients, compared with HD patients, experience a higher satisfaction with marital life, especially in terms of personality issues, communication, conflict resolution, leisure activities, sexual relationships, children and parenting, and religious orientation

This article lays the groundwork for a defense of rational intuitions by first arguing against a prevalent view according to which intuition is a distinctive psychological state, an “intellectual seeming” that p, that then constitutes evidence that p. An alternative account is then offered, according to which an intuition that p constitutes non-inferential a priori knowledge that p in virtue of the concepts exercised in judging that p. This account of rational intuition as the exercise of conceptual capacities in a priori judgment is then distinguished from the dogmatic, entitlement and reliabilist accounts of intuition’s justificatory force. The article concludes by considering three implications of the proposed view for the Experimental Philosophy movement.
