企业绿色创新驱动因素研究——基于资源型企业的实证

侧重于外部商业环境对企业绿色创新的影响,提出了企业绿色创新的5个驱动因素。以资源型企业为样本,在137份有效问卷的基础上,运用SPSS17.0软件及逐步多元回归方法实证检验了驱动效果。结果表明利益相关者的压力、外部网络支撑、创新的不确定性、政策预期和管理者的机会感知会渐次影响到企业的绿色创新,共解释了绿色创新变动的58.1%。将绿色创新划分为产品、过程和管理3种表现,按照驱动难度由小到大依次为管理、产品和过程。     

Blood zinc protoporphyrin, serum total protein, and total cholesterol levels in automobile workshop workers in relation to lead toxicity: Our experience

Blood zinc protoporphyrin (ZPP), serum total protein (TP), and total cholesterol (TC) levels in automobile workshop workers in relation to lead toxicity were analysed. In the present study, automobile workshop workers (healthy male workers at an age between 28 and 35 from four major automobile workshops in Kottayam, Kerala State, India) and the control (male healthy adults at an age between 28 and 35 residing at Aymanam, a distant village at Kottayam District, Kerala having reduced or no chance of lead exposure) displayed significant difference in blood lead (BPb) and blood ZZP (BZPP) level. The mean value of BPb in automobile workshop workers was 15.76±0.33 μg/dl, while in the control it was 8.20±0.15 μg/dl. In automobile workshop workers, the mean value of BZPP was 34.2±0.62 μg/dl. The control group exhibited a mean of 11.5±0.22 μg/dl. Automobile workshop workers exhibited significant increase in BZPP was corresponding to the increase in BPb level. The total protein levels estimated in automobile workshop workers showed significant decrease compared to control individuals, but was within the reference range of healthy individuals. The mean value of TP level in automobile workshop workers and control was 6.9±0.13 g/dl and 7.71±0.18 g/dl, respectively. There was no significant difference in blood haemoglobin (BHb) level among the automobile workshop workers and control. The serum TC level in automobile workshop workers showed significant decrease compared to the control individuals, but was with in the reference range of healthy individuals. The mean level of serum TC in automobile workshop workers was 162.00±3.44 mg/dl and the same in control was 172.86±4.32 mg/dl. The present study affirms occupational lead toxicity in automobile workshop workers and its effect on serum protein and cholesterol levels.     

饱和土体中半封闭压力隧洞的应力和位移场

基于Biot固结理论，研究分析了饱和土体中半封闭压力隧洞问题，建立了压力隧洞的半封闭边界条件．通过对控制方程的解耦，得到了孔隙水压力的消散方程．在Laplace变换域中得到隧洞边界上作用轴对称荷载和流体压力条件下的应力、位移和孔隙水压力解答，考虑了土体和孔隙流体的压缩性，运用Laplace数值逆变换得到时域中的解．文末给出了算例，分析了隧洞的半封闭特性对应力、位移和孔隙水压力的影响。
