论高职院校思政教师的教学底气与社会实践

高职院校思想政治理论课教师的"教学底气"十足与否,关系到能否充分发挥思政课在高职院校大学生思想政治教育中的主渠道和主阵地作用,关系到能否实现中国特色社会主义高等职业教育人才培养的思想政治目标,关系到能否育成为实现中华民族伟大复兴"中国梦"而奋斗接力、忠诚效力的职业生力军。高职院校思政课教师教学的十足底气离不开社会实践,只有通过社会实践思政课教学才能接地气,思政课教师才能做到论实结合、以实证论地讲真、讲实,思政课教师教学才能有底气,有了底气的思政课教学才对高职院校的大学生产生说服力、吸引力、感召力,突显思想政治理论育人塑魂的重要作用。     

应用DNA彗星电泳法检测辐照食品

通过彗星电泳法检测样品单细胞DNA损伤从而鉴别辐照食品。[方法]选取12种食品基质,经1KGy、3KGy、5KGy、7KGy、10KGy剂量辐照后,进行彗星电泳检测,并对检测时效性进行研究。[结果]除熟制鸡肉外,其他样品均可通过彗星电泳法检测到辐照状况,检测灵敏度达lKGy辐照剂量;辐照产生的DNA损伤具有明显的剂量-效应关系,以TL、TDNA％指标分析存在平台期,以TM、OTM指标分析则不存在平台期：辐照后6h-5d均可检测到明显的彗星图像。[结论]彗星电泳法适用于除熟制食品外的含DNA食品的辐照检测,方法稳定性好,检测灵敏度高。

Analysis of the major drivers of the ecological footprint using the STIRPAT model and the PLS method—A case study in Henan Province, China

Taking Henan Province of China as an example, we computed and analyzed the ecological footprint (EF) in 1983–2006. The results showed that the EF in Henan Province quadrupled in the 23 years, but its ecological carrying capacity (EC) was rather low and was in a state of slow decline, indicating that Henan's ecological deficit (ED) had become a remarkable social problem. Therefore, the major drivers of the EF's change were analyzed. According to the simulations with STIRPAT model, the major drivers of Henan's EF were human population (P), GDP per capita (A₁), quadratic term of GDP per capita (A₂), percent of economy excluded in the service sector (Ta₁) and percent of urban population (Tb₁). However, these drivers themselves had strong collinearity, which might produce some uncertain impact to the final results. In order to avoid the impact of collinearity, the method of partial least squares (PLS) was used. The results showed that the major drivers of EF were P, A₁, A₂ and Tb₁. Ta₁ was excluded. Compared with the results by the STIRPAT model, which showed that P is the most dominant driver and the effect of the other drivers could almost be ignored, the results by PLS method were considered as more reasonable and acceptable because the impacts of the A (Affluence) and T (Technology) conditions to the regional EF were still too important to be ignored. In addition, the results acquired by both methods showed that the curvilinear relationship between economic development and ecological impact (EF) or the classical EKC hypothesis didn't exist in Henan Province.
