大学"行政化"的形成有着复杂的历史因素和现实因素,是必须要克服的倾向。大学"去行政化"有着特定的内涵,必须严格区分两种不同的含义。大学"去行政化"不是弱化"行政",而是要加强、改进行政,实现科学行政,高效行政。

不事教育的教育学——论现代教育学的使命

四川师范大学学报（社会科学版） 2012年第3期39卷 75-77页

作者：荣司平泰州师范高等专科学校江苏泰州225300

作为学问形态的教育学并不"教人为师",而是探索教育中的真理。现代教育学中的工具主义、实用主义、功利主义只能导致教育学真实使命的遮蔽。以真理为志向的教育学是一项艰苦卓绝的智识活动,对研习者具有较高的要求。

　　Raltitrexed (8), a new quinazoline-based inhibitor of thymidylate synthase (TS), has been registered widely for the first-line treatment of advanced colorectal cancer. [1,2] As reported in the literature, [3,4] it can be prepared from 2-thiophenecarboxylic acid via 7 steps in 3% overall yield, but n-BuLi and the low temperature at - 78 ℃ was needed for the introduction of 5-carboxyl group into thiophene ring through lithiation of 2-(N-Boc-N-methylamino) thiophene followed by the addition of CO2. Here we wish to report a new route for the synthesis of Raltitrexed which was obtained from 2,5-thiophenedicarboxylic acid via 6 steps in 18.2% overall yield (Scheme 1). The mild conditions utilized in the synthetic route avoid the use of n-BuLi, NaH and the experimental conditions of low temperature at - 78 ℃ and strictly free of water, and are suitable for the large-scale preparation.……

吕梁山花岗岩风化土与长江以南的花岗岩风化土具有较大差异。为了全面认识花岗岩风化土的力学性状,并为合理评价山区路基填料的工程性质提供依据,通过常规物理力学试验和大三轴试验,评价了吕梁山压实花岗岩风化土的基本物理特性和强度特性,发现所研究风化土在较低围压下即表现出颗粒破碎特性。参照既有研究成果,修正了花岗岩风化土峰值应力比M_f和状态应力比M_c的关系,确定了吕梁山压实花岗岩风化土的弹塑性本构模型。基于等向压缩-卸载试验与初始剪切的连续性假定,结合邓肯-张模型,最终获得了修正强度条件下风化土本构关系的所有模型参数。通过比较计算和试验结果,验证了峰值应力比与状态应力比的乘积为平均主应力的幂函数关系的合理性。

新一轮的集体林权改革已经开展了6年,对这一轮改革及时进行评价,不但对于认识改革的效果有积极的作用,而且对于有效地推进改革也是必不可少的。本文通过分成地租模型预测,集体林权改革对林产品生产效率会产生正向的影响,这些正向的影响主要包括林户劳动积极性的提高和林产品产量的增加,同时也可能会对林产品全要素生产率产生积极影响。利用此次林权改革的主要省份之一——福建2县11乡(镇)29村320林户调查数据,本文的研究结论证实了前者,林户劳动投入由改革前146.53工日增加到改革后的180.76工日,增长了23%;竹产品的产量也由改革前的1 312.33 kg增长到改革后的1 815.09 kg,增加了38%。另外,基于肯德里克方法,本文计算了集体林权改革前后林产品全要素生产率,对比二者发现,改革对林产品全要素生产率并没有产生正向的影响,相反而是负向的影响。据此本文提出,下一步的林业改革在做好相关配套改革的基础上,还要注重提高林产品全要素生产率。
