烟草硫氧还蛋白基因NtTRX-hl的克隆和功能分析

从烟草中克隆了硫氧还蛋白基因NtTRX-hl并推导出其氨基酸序列,系统进化关系分析表明,NtTRX-hl与小麦、大麦、拟南芥等多种植物的TRX蛋白有很高的同源性.构建高效表达载体,诱导表达重组菌得到分子大小为22.26 kD的融合蛋白,与推测的分子量一致.用胰岛素和二硫苏糖醇作底物进行酶活性测定表明,Nt-TRX-hl具有活性.采用生物信息学的方法和工具分析了NtTRX-hl蛋白的生化参数和亚细胞定位,预测了该蛋白的高级结构.

发展政府与政府的科学发展

在中央提出科学发展观之后，各个领域都面临一个科学发展的问题。政府作为社会治理的主体，在推进科学发展上具有更为重要的作用，因此科学发展观要求政府自身必须首先科学发展。政府的科学发展必然包括政府自身的发展和面向社会治理能力的发展。果有善治则必有善政，因此必须大力发展政府，构建中国特色的发展政府学，借鉴全球发展政府的理论成果，研究中国政府发展的规律，为中国各级政府的改革和全面履行科学发展观职能提供理论及实践指导。     

Implied Preference for Seismic Design Level and Earthquake Insurance

Seismic risk can be reduced by implementing newly developed seismic provisions in design codes. Furthermore, financial protection or enhanced utility and happiness for stakeholders could be gained through the purchase of earthquake insurance. If this is not so, there would be no market for such insurance. However, perceived benefit associated with insurance is not universally shared by stakeholders partly due to their diverse risk attitudes. This study investigates the implied seismic design preference with insurance options for decisionmakers of bounded rationality whose preferences could be adequately represented by the cumulative prospect theory (CPT). The investigation is focused on assessing the sensitivity of the implied seismic design preference with insurance options to model parameters of the CPT and to fair and unfair insurance arrangements. Numerical results suggest that human cognitive limitation and risk perception can affect the implied seismic design preference by the CPT significantly. The mandatory purchase of fair insurance will lead the implied seismic design preference to the optimum design level that is dictated by the minimum expected lifecycle cost rule. Unfair insurance decreases the expected gain as well as its associated variability, which is preferred by risk-averse decisionmakers. The obtained results of the implied preference for the combination of the seismic design level and insurance option suggest that property owners, financial institutions, and municipalities can take advantage of affordable insurance to establish successful seismic risk management strategies.     

市场竞争条件下成人高等教育发展的困境与突破

改革开放以来，我国经济体制从计划走向市场，并逐步趋于完善。经济体制的转变带来了成人高等教育活动的变革。市场竞争条件下成人高等教育发展呈现出竞争性、合作性、品牌化、多样性和适应性等特征。然而，我国成人高等教育却存在着地位不明、竞争力弱、质量偏低、单一化、趋同化等问题。我们只有对成人高等教育进行系统改革，才能建立与现代市场经济体系相适应的成人高等教育体系。

Effects of Marriage and Children on Financial Risk Tolerance: A Synthesis of Family Development and Prospect Theory

Family development and prospect theory were used as a framework to predict variability in individuals' subjective financial risk tolerance within distinct family structures. Gender, age, and income were expected to interact with the main effects of family structure (marital status and children). Theory-generated hypotheses were examined in Study 1 (data from university housing respondents, n = 76) and Study 2 (the 1998 Survey of Consumer Finances, n = 4,305). One family structure main effect (child presence) was significant for investment risk tolerance in both studies. Family structure interactions (marital status × age and child × income) were significant for employment risk (Study 1), and child × age was significant for investment risk in Study 2.
