本研究使用2004-2014年间42个国家的数据,对保险影响撒哈拉以南非洲地区的收入不平等状况进行了考察。研究应用了三个反映不平等的变量--基尼系数、阿特金森指数和帕尔马比值。我们选取两种保险费进行考察,即人寿保险和非人寿保险,并根据广义矩估算法(GMM)获得实证数据。人寿保险能提高基尼系数,提升人寿保险对基尼系数和阿特金森指数具有净正效应。非人寿保险会降低基尼系数,提升非人寿保险对帕尔马比值具有净正效应。将该分析拓展,确定政策阈值--达至该阈值,增加保险费就会完全抵消净正效应。由此拓展分析可知,人寿险保费7.500(占GDP的百分比)即是人寿保险对不平等状况形成负效应的临界量,而非人寿险保费0.855(占GDP的百分比)则是非人寿保险对不平等状况产生负影响的阈值。本研究提出了政策阈值,在这些阈值内的保险深度可减轻撒哈拉以南非洲地区的收入不平等状况。

The aim of the present study was to evaluate the nutritional quality of green and purple eggplant, their antioxidant activity and their nutritional efficacy on Wistar rats. For nutritional quality, the parameters measured are dry matter, protein, lipid, ash, carbohydrate, iron, phosphorus, calcium, magnesium and energy content. For antioxidant activity, the parameters measured are 50% DDPH free radical inhibition concentration and total polyphenol content. Nutritional efficacy was evaluated in rats fed the control diet and in rats fed the three treated diets containing eggplant meal obtained by replacing 5%, 10%, and 15% of the control diet. The parameters measured are the amount consumed, the weight of the animal and target organs, and hematologic parameters. The results of the nutritional analysis show the following values: 13.31% protein, 2.66% lipids, 0.84% calcium, 0.12% magnesium, 0.43% phosphorus for the Solanum aethiopicum L. species and 13.47% protein, 3.66% lipids, 0.36% calcium, 0.22% magnesium, 0.35% phosphorus for the Solanum melongena L. species. In terms of antioxidant activity, we obtained DDPH inhibition percentages of 40.28 mg/ml for Solanum aethiopicum L. and 12.42 mg/ml for Solanum melongena L., respectively. Finally, hematologic and anthropometric tests showed that for the different diets used, weight loss and an increase in hematologic parameters were observed in the rats tested. This study showed that eggplant has interesting nutritional characteristics and antioxidant activity, contributing to an increase in weight and anthropometric parameters.
