高职教育“123543”人才培养范式的研究与实践

高职教育到底培养什么样的人,怎样培养人,是值得我们深思的问题.人才培养模式的改革要解决这些问题,要全面提高人才培养质量,必须从校企合作、工学结合、课程改革等方面进行实践.西安航空职业技术学院在总结人才培养工作的基础上,形成了"123543"人才培养范式.该范式的经验可以对其他高职院校教学改革起到积极的引导和借鉴作用.     

优势视角的学校社会工作辅导策略探析

优势视角理论是20世纪八九十年代兴起于西方社会工作领域的一个新的实践取向。文章介绍了优势视角理论的基本观点:建构主义的哲学基础、多元取向的分析原则、弹性灵活的操作步骤和平等合作的辅导关系。在此基础上,文章结合两年来在中学开展的现场研究,提出了优势视角的学校社会工作辅导策略:此时此地、外化提问、积极回应、寻求代替、亲身体验和回归日常,并对此进行了反思与讨论。     

Effective extraction of elastase from Bacillus sp. fermentation broth using aqueous two-phase system

INTRODUCTION Aqueous two-phase system (ATPS) is widely used in biochemistry and biotechnology for purifica- tion of proteins (Diamond and Hsu, 1992; Balasubramaniam et al., 2003), enzymes (Pan et al., 2001; Bim and Franco, 2000), amino acids (Li et al., 2002), antibiotics (Yang et al., 1994; Guan et al., 1994), nucleic acids (Ohlsson et al., 1978; Kimura, 2000), aroma compounds (Marco et al., 2000) and lactic acid (Planas et al., 1998). ATPS is mainly composed of two-incompatible p…

三角形packing问题中零自由度动作的分类

三角形packing问题中三角形可以进行连续平移和旋转,如果不对三角形放置动作进行限制,则计算将无法实现。本文提出了零自由度动作概念,并对它进行了详细的分类,为求解三角形Packing问题建立了一个接近客观情况的模型。     

微孔膜内大分子有效扩散系数的计算

报道一种计算分子尺寸与构型对微孔内大分子有效扩散系数影响的理论方法。基于刚性圆球分子在圆柱型孔内的扩散理论，定义分子平均投影半径和水力学球半径，分别用于估算孔内外浓度分配系数和孔内水力学拖曳力。对不同构型的大分子，使用该法计算的有效扩散系数与已发表的实验数据吻合良好。     

走向校本的素质教育——天津市中小学实施素质教育的研究

一、走向校本———素质教育深化发展的必然从20世纪80年代开始,我国就在不同层面出现了素质教育的实践探索,而且涌现了一批成功的素质教育模式,如“成功教育”、“和谐教育”、“愉快教育”等,并且在不同层面进行了宣传和推介。从1996年起,原国家教委还从区域性层面对实施素质     

Allograftic bone marrow-derived mesenchymal stem cells transplanted into heart infarcted model of rabbit to renovate infarcted heart

Objective: To investigate the directed transplantation of allograftic bone marrow-derived mesenchymal stem cells (MSCs) in myocardial infarcted (MI) model rabbits. Materials and Methods: Rabbits were divided into 3 groups, heart infarcted model with MSCs transplanted treatment (MSCs group, n=12), heart infarcted model with PBS injection (control group, n=20), sham operation with PBS injection (sham group, n=l 7). MSCs labelled by BrdUrd were injected into the MI area of the MSCs group. The same volume of PBS was injected into the MI area of the control group and sham group. The mortality, LVIDd, LVIDs and LVEF Of the two groups were compared 4 weeks later. Tropomyosin inhibitory component (Tn I) and BrdUrd immunohistochemistry identified the engrafted cells 4 weeks after transplantation. Result: The mortality of the MSCs group was 16.7% (2/12), and remarkably lower than the control group's mortality [35% (7/20) (P＜0.05)].Among the animals that survived for 4 weeks, the LVIDd and LVIDs of the MSCs group after operation were 1.17±0.21 cm and 0.74±0.13 cm, and remarkably lower than those of the model group, which were 1.64±0.14 cm and 1.19±0.12 cm (P＜0.05); the LVEF of the MSCs group after operation was 63±6%, and remarkably higher than that of the model group,which was 53±6% (P＜0.05). Among the 10 cases of animals that survived for 4 weeks in the MSCs group, in 8 cases (80%),the transplanted cells survived in the non MI, MI region and its periphery, and even farther away; part of them differentiated into cardiomyocytes; in 7 cases (70%), the transplanted cells participated in the formation of blood vessel tissue in the MI region. Conclusion: Transplanted allograftic MSCs can survive and differentiate into cardiomyocytes, form the blood vessels in the MI region. MSCs transplantation could improve the heart function after MI.

用改进的元胞自动化模型模拟不同信号灯控制策略下的交通流

Traffic flows controlled by traffic light strategies were investigated via a cellular automaton model with anticipation, which is suitable for describing urban traffic. Three kinds of strategies, i. e., synchronized, green-wave and random switching lights, were designed, simulated and compared with each other. It is shown that the green-wave strategy is only valid at lower density and there is not an effective way with the three strategies to improve the efficiency of traffic flow at high density.
