入世后西部地区如何抑制第二次人才快速外流

加入WTO后，跨国公司和东部企业为争夺人才竞相出台了优惠的政策，导致了西部地区继改革开放之后第二次人才快速外流。西部地区必须从政府宏观和企业微观两个层面着手，采取一系列积极有效的政策措施，来抑制人才的快速外流。     

关于身体权的法律思考

身体权作为一种独立的人格权,包括了维护身体形式上和实质上的完整性和有限制自由支配身体的排他性权利。对于胎儿已戚人形的身体,应由其出生后获得权利能力的自然人来追溯行使身体权;对‘于尸体则认为是身体权客体的延续利益,不应再尊有身体权。对于侵害身体权的赔偿应以精神损害赔偿为主,财产损害赔偿为辅,以达到维护民亨主体人格尊严,保障其人格利益的终极目的。

Ring‐opening grafting polymerization of cyclic monomers onto human hair

Natural human hair was successfully modified by the graft polymerization of trimethylene carbonate, β‐propiolactone, ε‐caprolactone, glycidol, ε‐caprolactam, and 5,5‐dimethyl‐1,3‐dioxane‐2‐thione. In contrast, we could not modify natural human hair by the graft polymerization of oxetane under similar conditions. The model reaction suggested that the main initiating species in these polymerizations were the amino, thiol, and hydroxyl groups in hair, which could induce ring‐opening polymerization. Among the tested monomers, β‐propiolactone was most effective for hair modification with its graft polymer, whose concentration was as high as 0.5 g/g of hair though polymerization under mild conditions. The effects of the hair pretreatment and polymerization temperature on the weight ratio of the grafted polymers were also investigated. Hair modified by grafted polymers was characterized with scanning electron microscopy and Fourier transform infrared measurements. © 2007 Wiley Periodicals, Inc.

Interpretation of inorganic arsenic metabolism in humans in the light of observations made in vitro and in vivo in the rat

The toxicity of inorganic trivalent arsenic for living organisms is reduced by in vivo methylation of the element. In man, this biotransformation leads to the synthesis of monomethylarsonic (MMA) and dimethylarsinic (DMA) acids, which are efficiently eliminated in urine along with the unchanged form (As_i). In order to document the methylation process in humans, the kinetics of As_i, MMA and DMA elimination were studied in volunteers given a single dose of one of these three arsenicals or repeated doses of As_i. The arsenic methylation efficiency was also assessed in subjects acutely intoxicated with arsenic trioxide (As₂O₃) and in patients with liver diseases. Several observations in humans can be explained by the properties of the enzymic systems involved in the methylation process which we have characterized in vitro and in vivo in rats as follows: (1) production of As_i metabolites is catalyzed by an enzymic system whose activity is highest in liver cytosol; (2) different enzymic activities, using the same methyl group donor (S-adenosylmethionine), lead to the production of mono- and di-methylated derivatives which are excreted in urine as MMA and DMA; (3) dimethylating activity is highly sensitive to inhibition by excess of inorganic arsenic; (4) reduced glutathione concentration in liver moderates the arsenic methylation process through several mechanisms, e.g. stimulation of the first methylation reaction leading to MMA, facilitation of As_i uptake by hepatocytes, stimulation of the biliary excretion of the element, reduction of pentavalent forms before methylation, and protection of a reducing environment in the cells necessary to maintain the activity of the enzymic systems.

运动员人力资本的不确定性与足球职业俱乐部治理特征

人力资本是分析职业足球俱乐部的治理结构的起点,人力资本的各种特征所内含的不确定性将在足球俱乐部治理和俱乐部的持续发展中起核心作用.通过分析运动员的人力资本特征,主要包括:运动员是其人力资本的“自然”所有者和承担者,具有不可分性,走运动员的主动资产;运动员人力资本具有不完全替代性,并通过团队活动获得不同程度的垄断权力,有获取报酬递增的趋势;以及运动员人力资本的不确定性.俱乐部最重要的资产是运动员的人力资本资产,因此,俱乐部必须充分考虑运动员行为的不确定性,其治理结构必须符合人力资本的特征,激励合约必须面向未来.
