高校教师创新能力培养的问题与对策

论文认为,高等教育的任务是为创新型国家建设和社会发展培养具有创新精神和实际能力的高级专业人才.在完成这项任务的过程中,教师是关键因素;因此,高校必须注重提高教师各方面的素质,特别是培养教师的创新能力.用建设创新型国家所需要的高标准来要求我们的高校教师队伍,仍然有不小差距和不少问题存在.这些问题有严重的危害性,必须下大力气去纠正.高校教师创新能力的培养和提高的对策与途径,可以归纳为几点:(1)采取措施创建学术自由的环境;(2)有计划地培养和提高教师的学术素养;(3)应建立客观公正的学术评价机制;(4)强化高校教师的教学责任;(5)做好教师的个人职业生涯规划;(6)提高教师的社会实践应用能力.     

以人为本理念下酒店管理实习生柔性人性化管理探析

论文认为酒店业未来可持续发展的关键因素是“人”的因素.酒店服务质量的提高有利于增强酒店的竞争能力和可持续发展,而服务质量的好坏取决于员工的服务态度以及酒店服务的全方位管理.高职酒店管理专业实习生是酒店人力资源重要组成部分.高职酒店大学生的实习是整个教学计划中的重要环节,实习过程对实习生、企业和学校都起着举足轻重的作用.如何留住实习生,充分发挥他们工作的积极性和主动性是酒店管理的一大难题.重新认识实习生的重要性,以人为本,将柔性人性化管理理念引入到实习生管理是酒店的当务之急.     

泛北部湾区域旅游形象研究

泛北部湾旅游合作成为广西北部湾经济区发展的重要内容,对区域内各国及广西的旅游发展具有重要影响.泛北部湾旅游区域作为一个整体尚不具有统一的旅游形象,这对泛北区域的旅游合作有不利影响.通过对泛北部湾地区旅游资源特点和旅游客源市场的深入分析,提出相应的旅游形象定位及主题口号,以期对泛北部湾区域旅游合作发挥一定作用.     

基于全寿命周期的建设项目环境成本研究

建筑业带来经济效益和使用价值的同时,却在透支环境资源.论文基于当前只重视经济效益而忽视环境成本的现实,通过分析建设项目全寿命周期各阶段对环境的影响,提出环境成本计量模型,并通过对某住宅小区建设项目全寿命周期内影响环境的因素进行分析,计量环境成本,得出原材料获取阶段和维护使用阶段的环境成本较高的结论,并对环境成本管理提出建议.     

水体类旅游资源可亲性评价因子分析

水体旅游资源的功能性是水体旅游资源评价体系当中的一项空白。论文提出以水体旅游资源可亲性作为衡量水体旅游资源功能性的标准。通过对水体旅游资源本底属性和旅游者对该水体资源的感知两方面进行分析,选择了水质等几项因素作为衡量水体类旅游资源可亲性的评价因子,并对各评价因子的具体选择原因及作用进行了分析。     

Investigation on the Orientation Transition of Oriented Magnetostrictive TbDyFe Crystals

<110> and <112> TbDyFe magnetostrictive oriented crystals were prepared by the zone-melting unidirectional solidification method at 240 mm/h and 720 mm/h respectively. <112> oriented crystals were also obtained with <110> oriented seeds with the same technique as for growing the <112> oriented crystals. It is confirmed that this technique is stable for growing the oriented crystals in the TbDyFe alloys. Meanwhile, the variation of orientation, the solidification morphology and the magnetostriction were studied during the transition from <110> oriented seeds to the <112> oriented crystal growth. As the growth speeds up, the preferred orientation changed from <110> to <112>, and its morphology develops from of initial cellular to dendritic gradually. When an axial compressive pre-stress of 10 MPa is applied, the magnetostriction at the bottom, the middle and the top are 972×10-6, 918×10-6 and 900×10-6 at 100 mT respec-tively. The middle sections with mixed orientations have the same high magnetostriction performance as those with a single preferred orientation, which may be due to its celluar-dendritic morphology.

影响强夯加固范围的主要因素有夯击能、夯锤面积、夯击次数、土体性质等,在分析这些影响因素的基础上,采取量纲分析的方法,建立了路基强夯加固的深度方程,并考虑土体的级配与含水量修正系数,建立了强夯加固深度的计算公式.最后和工程测试的有效加固深度进行对比,表明该公式与实际测试结果较为符合,证明该公式的有效性和可信性.     

渐变结构系统模糊可靠性灵敏度分析的矩方法(英文)

For a degradable structural system with fuzzy failure region, a moment method based on fuzzy reliability sensitivity algorithm is presented. According to the value assignment of performance function, the integral region for calculating the fuzzy failure probability is first split into a series of subregions in which the membership function values of the performance function within the fuzzy failure region can be approximated by a set of constants. The fuzzy failure probability is then transformed into a sum of products of the random failure probabilities and the approximate constants of the membership function in the subregions. Furthermore, the fuzzy reliability sensitivity analysis is transformed into a series of random reliability sensitivity analysis, and the random reliability sensitivity can be obtained by the constructed moment method. The primary advantages of the presented method include higher efficiency for implicit performance function with low and medium dimensionality and wide applicability to multiple failure modes and nonnormal basic random variables. The limitation is that the required computation effort grows exponentially with the increase of dimensionality of the basic random vari- able; hence, it is not suitable for high dimensionality problem. Compared with the available methods, the presented one is pretty competitive in the case that the dimensionality is lower than 10. The presented examples are used to verify the advantages and indicate the limitations.
