经济人的理性选择与社会人的流动渠道--对"考研热"的经济学与社会学分析

本文引用中华英才网近五年的薪资调查数据，运用成本一收益的净现值、内部收益率、明瑟收益率等多个指标，衡量继续接受硕士教育相对于本科毕业后直接就业的比较优势；并试图从社会学的角度分析“考研热”的形成不仅是大学生为了缓解就业压力、增加求职筹码而做出的理性选择，还可能是借助高等教育这样一种“信号机制”，实现“向上流动”的个人理想、获得更高的社会地位。     

Effects of light and temperature conditions on flowering in Mat Rush

The effects of photoperiod and light intensity on flowering in Mat Rush cv. Gangshan 3 were studied. The results showed that treatments with longer day length stimulated flowering significantly and increased stem flowering percentage (SFP). Plants treated with low light intensity at early stage had substantially reduced florets per cyme, SFP, tillers per plant and stem length. At middle and late stage, low light intensity significantly reduced SFP. The principal climatic factors affecting SFP were as follows: mean temperatures (MT) of the third ten-day period (TDP) in December and of the second TDP in February, actual sunlight hours (SH) of the third TDP in February and precipitation of the third TDP in March. A nonlinear simulation model for SFP was established with experimental results and corresponding climatic data (see Eq. (2)). Simulation by the above equation yielded values the same as those observed from 1992 to 2000, indicating its accuracy in describing the relationship between flowering and light and temperature conditions. The interaction between vernalization and SH is also discussed in this paper. Project (No. 981105) supported by the Ningbo City Science Foundation, China

高校本科毕业生就业率的区域经济影响因素分析

基于麦可思公司公布的中国2008届大学毕业生求职与工作能力调查的统计数据,在考虑省际空间效应影响的前提下,运用经典回归和空间自回归模型,实证分析了影响我国内地本科高校毕业生就业率的省域社会经济因素。结果发现,省域城镇化率、第三产业就业人数、人均地区生产总值和毕业生人数都对本省本科毕业生就业率产生积极影响;非211高校本科毕业生就业率在省域之间存在空间依赖性和空间溢出效应。     

高职院校实训设备资金投入对就业率影响的阻滞增长模型

高职院校每年新增实训设备生均值是影响毕业生就业率的重要因素,建立两者关系的阻滞增长模型,求出单位资金的利用效率最大时的新增实训设备生均值,对各高职院校实训设备投入资金的管理有一定参考价值。     

荀子礼的社会理想价值及其哲学论证
