the present paper aimed at studying the current models of credit portfolio management. there are currently three types of models which consider the risk of credit portfolio: the structural models (moody's kmv model, and credit- metrics model), the intensity models (the actuarial models) and the econometric models (the macro-factors model). the development of these three types of models is based...

conclusions the prevalence of msds among the nurses was high, and the occurrence of such disorders was found to be related to the scores of mapo and ptai indices. based on the results, these two indices can be used as appropriate tools to assess the risk of msds in patient handling by nursing staff. the risk of developing msds can be lowered through interventional programs, such as providing an...

The growing importance of enterprise risk management and the resulting integration efforts put the need for separate IT risk management frameworks in question. In this research we analyse common and distinct elements of the COSO enterprise risk management and ISACA Risk IT frameworks. The analysis affirms the hypothesis that separate IT risk management frameworks are redundant.

Tail risk refers to the risk associated with extreme values and is often affected by extremal dependence among multivariate extremes. Multivariate tail risk, as measured by a coherent risk measure of tail conditional expectation, is analyzed for multivariate regularly varying distributions. Asymptotic expressions for tail risk are established in terms of the intensity measure that characterizes...

The effect of ulcérationof the urinary bladder on bladder carcinogenesis induced by W-[4-(5-nitro-2-furyl)-2-thiazolyl]formamide (FANFT) or sodium saccharin was evaluated in 5week-old F344 rats which were all killed 2 years after the start of the experiment. The results indicate that long-term feeding of sodium saccharin, a nonmutagen, appears to be capable of inducing bladder tumors if admini...

background: the area of contaminated lands exposed to the health risk of environmental pollutants is a matter of argument. in this study, a new method was developed to estimate the amount of area that is exposed to higher than normal levels of cr, mn, and v. methods: overall, 170 soil samples were collected from the upper 10 cm of soil in an arid area in central part of iran in semnan province....

BACKGROUND The objective of the study was to investigate the effects of in vitro zinc sulphate additive to semen extender on sperm parameters (progressive motility, viability, membrane integrity and DNA stability) after cryopreservation. MATERIALS AND METHODS In this Prospective longitudinal laboratory study, semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occa...
