《金色笔记》与莱辛的女权主义思想

《金色笔记》中的女主人公们具有强烈的女性意识,渴望独立与自由,但处于以男权文化为中心的社会中,她们会不可避免地陷入某种生存困境;男女间的世界其实不应对立,而应是相辅相成的;妇女解放是全世界进步中的一个问题,只能随着其它问题的解决而逐步解决。作者多丽丝.莱辛不能说是旗帜鲜明的女权主义者,但确是一位有着独特的女权主义思想和明确的女性意识的作家。     

Oxidative stress increases continuously with BMI and age with unfavourable profiles in males

Oxidative stress is a risk factor for chronic diseases and was previously shown to be independently associated with obesity. The authors investigated the relationship between body mass index (BMI), age and oxidative stress on 2190 subjects undergoing a health care examination. Total antioxidant status (TAS), total peroxides (TOC) and autoantibodies against oxidized LDL (oLAb) were used as oxidative stress biomarkers in addition to serum lipoproteins, bilirubin and uric acid. Gender-specific differences were observed for age, BMI, serum concentrations of bilirubin, low-density lipoprotein (LDL), uric acid and TAS, all of which were higher in males (p < 0.001), while high-density lipoprotein (HDL), HDL/LDL ratio and TOC were higher in females (p < 0.001). Total cholesterol (p < 0.05) and LDL were increased (p < 0.05), while HDL was decreased (p < 0.05) in overweight and obese subjects. This was accompanied by increased uric acid and TAS concentrations. Lowest oLAb titers were detected in obese subjects. In extremely obese subjects, increased TOC and decreased TAS were observed in spite of high uric acid levels. These results demonstrate that oxidative stress increases with increasing BMI and age, as a sequel to an impaired antioxidant status, the consumption of oLAbs, an increase of peroxides and uric acid and a disadvantaged lipid profile.     

The price-quality relationship: A heuristic model

An on-the-shop-floor experiment is carried out to determine the price-quality relationship for a number of toiletries. Three different and distinct demand curves are obtained. A heuristic model to describe these curves is constructed. The implications of this model for the profit-orientated businessman are then analysed.
