background: radon is the second leading cause of lung cancer after smoking. in canada, the health authorities have no access to comprehensive profile of the communities built over uranium-rich micro-geological settings. the present indoor radon monitoring guideline is unable to provide an accurate identification of health hazards due to discounting several parameters of housing characteristics....

Site preparation plays a vital role in British Columbia’s regeneration program (Figure 1). Historically, prescribed fire has been the tool most commonly used to satisfy the needs of both hazard abatement and site preparation. Recently, the use of fire has decreased relative to other options (Figure 2), due to the increased cost of burning, the increased public concern in areas sensitive to smok...

the present nuclear leakage crisis from japan is a topic to be discussed in present public health. in radiology, the leaked radioactive elements are considered hazard. here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. based on previous similar nuclear crisis in russia, it is eviden...

We examine the performance of large credit markets subject to borrower moral hazard, when information on the past behavior of borrowers is subject to bounded memory constraints. Borrowers who default should be temporarily excluded in order to efficiently incentivize repayment. However, lenders have an incentive to lend to borrowers who are near the end of their exclusion period, undermining thi...

INTRODUCTION The radioactive isotopes of ruthenium with mass numbers 103 and 106 are common fission products and may represent a radiological hazard for the population in case of their release into the environment and transfer to the food chain. Ru, having a half-life of 39.26 d, decays by β emission onto Rh. Ru (T1/2=374 d) is a pure β emitter, and its daughter nuclide, Rh, is radioactive as w...

This paper presents a principal-agent model of IMF conditional lending, in the aftermath of a “capital-account” liquidity crisis. We show that traditional ex-post conditionality can be e¤ective in safeguarding the Fund’s resources, allowing for the provision of e¢cient emergency lending and reducing ine¢cient ex-ante credit rationing if the capital out‡ow which triggers the crisis is not excess...

Thunderstorm case studies and earlier observations are described which illuminate the relationship between cloud vertical development and the prevalence of intracloud (IC) and cloud-to-ground (CG) lightning. A consistent temporal evolution starting with peak IC activity changing to predominant CG activity and concluding with strong outflow (microburst) suggests that ice is responsible for both ...

This paper motivates a reduced form discrete-time series approach that models realized volatility by using its separated components, continuous variation and variation due to jumps. For this purpose, I combine Engle and Russell’s (1998) autoregressive conditional duration (ACD) model applied to the continuous and jump size variation with Hamilton and Jordà’s (2002) autoregressive conditional ha...
