evidence of adverse selection in irans health insurance market
در این تحقیق به مطالعه وجود انتخاب نامساعد(کژ گزینی) در بازار بیمه درمان تکمیلی ایران پرداخته شده است. داده های مورد نیاز توسط پرسشنامه و به روش نمونه گیری خوشه ای جمع آوری شده است. پرسشنامه ها در میان افراد شاغل ساکن شهر تهران توریع شد. در این تحقیق با استفاده از تخمین دو مدل لجستیک و به دست آوردن ضریب همبستگی میان تقاضای بیمه درمان تکمیلی و رخداد خسارت به بررسی موضوع مورد نظر پرداخته شده است....
15 صفحه اولWeighing in on Whole Grains: A Review of Evidence Linking Whole Grains to Body Weight1
Currently, an estimated 32.9% of American adults are overweight, 34.3% are obese, and 5.9% are extremely obese (38). In fact, adults defined as being normal weight, i.e., those whose body mass index (BMI) falls in the range of 18.5 to 24.9 kg/m2, are a minority within the U.S. population. Coupled with declines in physical activity, overconsumption of calorie-rich, nutrient-poor foods is contrib...
متن کاملNutrient Composition of Unprocessed Grains and Processed Grains
Nutrient composition of commercial corn grain appears to have changed little in the last 10 to 15 years. Although the data for sorghum grain and barley are more limited, no dramatic changes in nutrient composition were apparent. Flaking corn appears to reduce the crude protein concentrations, perhaps because water used for starch gelatinization is not released during drying. Harvesting and stor...
متن کاملDynamics of Vibrated Grains
We study number density distribution and the behavior of time correlation functions in the density of grains for a quasi-two dimensional system of vibrated grains. We study the system at various packing fractions, from low to high. At low densities we recover usual gas like behavior, reflected in a Poissonian statistics for the number density distribution. At higher densities we notice effects ...
متن کاملInterstellar Grains
Overview Submicron solid particles are dispersed through interstellar gas. These interstellar grains absorb and scatter light, thus shielding some regions from ultraviolet radiation, but also limiting our ability to detect photons which have been emitted by astronomical objects. Dust grains reradiate absorbed energy in the in-frared, thus contributing to the overall emission spectrum of astrono...
