Cultural and individual differences in self‐rating behavior: an extension and refinement of the cultural relativity hypothesis

This study examined the relationships between culture, individual attributes, and self‐rating behavior among 1,786 university students in Canada, Hong Kong, Taiwan, mainland China, and Japan, and in doing so extended and refined the cultural relativity hypothesis. It explored the difference between vertical and horizontal individualists in self‐rating behavior, and examined the mediating effects of two individual attributes, self‐enhancement propensity and general self‐efficacy in the relationship between individualism and self‐rating behavior. The results confirmed that individualism is the cultural driver for self‐rating leniency, and that the individual‐level assessment of individualism is a stronger predictor of self‐rating leniency than are culture‐level differences. Vertical individualism was found to be positively related to self‐enhancement propensity, which in turn was positively related to self‐rating. Whereas, horizontal individualism was positively related to general self‐efficacy, which in turn had a positive relationship with self‐rating. We discuss the implications of the results for academic research and practical management. Copyright © 2006 John Wiley & Sons, Ltd.

学分制在企业培训中的应用

学分制是在普通高等院校中应用比较普遍的一种教学制度，它的基本做法是：对每个专业的学生设定公共学位课、专业必修课和选修课，每修完、考过一门课程可获得2～4个学分，累积够一定学分，便可获得毕业证书，而不强制规定什么时间必须修什么课。与传统教学方式相比，学分制具有一些优势，如较大的灵活性、较强的激励性等，但同时也增加了管理的复杂性。

走科技办学之路

苏州市第三中学地震监测站始建于1976年唐山大地震后，至今29年如一日，监测设备从土变洋，房屋面积从小变大，工作人员从业余到专职，功能从单一的监测发展到多内容结合的防震减灾知识普及教育，三代老师一棒接一棒，使地震监测和防灾减灾宣传工作不断与时俱进。目前，学校的防震减灾科普教育基地已成为全国中学系统唯一规模较大、设备先进、成绩突出的，集地震监测、学生科技活动和面向社会宣传防震减灾知识三大功能于一体的科普教育基地。     

树脂相分光光度法测定水中痕量苦味酸

建立了树脂相分光光度法测定水中痕量苦味酸的新方法。该法灵敏度高,表观摩尔吸光系数为1.08×105L/(mol·cm);精密度理想(测定苦味酸质量浓度为5μg/mL的实验5次,相对标准偏差为1.0%);线性范围为0～7.0μg/mL;以3σ衡量,检出限为0.14μg/mL;加标回收率为97%～103%。采用该法直接测定水样中的苦味酸、间接测定烟草中的烟碱,结果令人满意。     

Quantification of intrinsic water use efficiency along a moisture gradient in Northeastern China

Water use efficiency (WUE) is an important ecophysiological characteristic of plants, especially in semiarid and arid regions. At the scale of community or ecosystem, WUE is difficult to quantify because the amount of water used per unit dry mass production is a function of microclimatic variables and species composition. In this study, we analyzed corrected intrinsic water use efficiency (IWUE(s)) of grass and shrub species along the western segment of the Northeast China Transect (NECT) and the relationship between IWUE(s) and mean annual rainfall, habitat degradation status, vegetation type, and plant functional type (C3 versus C4) at 22 survey sites. Site intrinsic water use efficiency (IWUE(v)) and its relationship with the aforementioned site variables were analyzed based on species frequencies at each site. First, it was concluded that photosynthetic pathway played a very important role in determining species IWUE(s). Mean IWUE(s) for C4 species was approximately double that of C3 species. Second, mean annual rainfall, vegetation type, and site degradation status significantly affected IWUE(s) (p < 0.01). Mean IWUE(s) at degraded sites was twice as high as that at nondegraded sites. The mean IWUE(s) for meadows was significantly higher than those for other vegetation types (p < 0.05). Third, the frequency of occurrence of C4 plants explained 36% of the variance in IWUE(v) across the survey sites. The mean frequency of C4 occurrence at degraded sites was more than double that at nondegraded sites. Consequently, mean IWUE(v) at degraded sites was more than double that at nondegraded sites. Dominant C4 species in saline-alkaline areas tended to have higher intrinsic WUE than dominant C4 species in sandy shrub communities.
