关于旅游管理本科实践教学改革的几点思考

本文重新界定了实践教学的概念,在此基础上指出应科学设计并不断优化实践教学体系,提出系统的实践教学设计应包括课内实践、课外实践、校内实践、校外实践、业内实践与业外实践等多个相互关联的环节,确保实践教学子系统有机整合于教学系统中,同时指出,规范科学、因实践性质而异的全程管理是实践教学达到预期目标的有力保障。     

Functional forms of the satisfaction–loyalty relationship

The linear functional form of the effect of customer satisfaction on repurchase intentions may not be adequate under all circumstances; however, we lack a clear understanding of the factors that may drive variation in the functional forms of the satisfaction-loyalty relationship. Building on existing research, the authors consider how the functional form of the effect of satisfaction on repurchase intentions varies across segments formed at the intersection of product categories and customer economic and demographic variables. A comprehensive data set obtained from the sponsors of the Chinese Customer Satisfaction Index provides the input for a flexible cubic regression configuration to model the functional forms. The linear functional form emerges as the most prominent across 972 product-customer segments (51%), followed in frequency by the S-shaped and convex forms and, finally, the inverse S-shape and concave forms. Different product category characteristics, customer economic and demographic variables, and market characteristics moderate the effect of satisfaction on repurchase intentions differently for the linear, quadratic, and cubic terms. This research reveals key resource allocation implications based on the functional forms of the effect of satisfaction on repurchase intentions, as well as strategic segmentation implications related to the varying influence of product category characteristics, customer economic and demographic variables, and market characteristics.     

Entrepreneurship,Innovation and Economic Growth: Evidence from GEM data

Studies on the impact of technological innovation on growth have been largely mute on the role ofnew firm formation. Using cross-sectional data on the 37 countries participating in GEM 2002, this paper uses an augmented Cobb–Douglas production to explore firm formation and technological innovation as separate determinants of growth. One area of interest is the contrast between different types of entrepreneurial activities as measured using GEM Total Entrepreneurial Activity (TEA) rates – high growth potential TEA, necessity TEA, opportunity TEA and overall TEA. Of the four types of entrepreneurship, only high growth potential entrepreneurship is found to have a significant impact on economic growth. This finding is consistent with extant findings in the literature that it is fast growing new firms, not new firms in general, that accounted for most of the new job creation by small and medium enterprises in advanced countries.

The effects of merchandise coordination and juxtaposition on consumers’ product evaluation and purchase intention in store-based retailing

Many retailers attempt to juxtapose and coordinate complementary products in their stores on the basis of key attributes because good coordination of complementary items can provide consumers with relevant information for their evaluation of individual products. In addition, the aesthetic appeal and the social impression that good coordination offers can be transferred to the products themselves. On the basis of these theories, the authors test the effects of merchandise coordination and juxtaposition (vs. separation) on consumer behavior using actual clothing items as stimuli in a laboratory setting. The authors find that coordination affects consumers’ evaluation of and purchase intention toward a target item only when the item is juxtaposed with a complementary item. This effect can be explained by the aesthetic response of consumers to and their social impression of a grouping of the items. Furthermore, in comparison with displaying the two items separately, juxtaposing them in a poorly coordinated manner appears to depress the target item's evaluation, though juxtaposing them in a well-coordinated manner does not seem to improve the evaluation.     

基于BSC和AHP的高校学生资助专项资金绩效评价指标体系构建

强化高校学生资助专项资金绩效评价既是国家资助政策的内在需求,也是优化财政资源配置、提高财政资金使用效益的有益举措。在全面实施预算绩效管理的背景下,依据平衡计分卡理论（BSC）,确定资金管理水平、满意度水平、内部管理水平和学习与成长水平等四个一级指标,在此基础上,通过借鉴学术研究成果、访谈和实地调研等方式筛选二级指标并应用层次分析法（AHP）进行赋值,最终构建出一套符合学生资助项目特点的绩效评价指标体系。结合指标体系构建结果,提出深入把握学生受助实际效果、注重培养大学生反哺社会的意愿并提升其能力、提高资助工作信息化水平、强化资助资金管理、加强学工队伍建设以提升资助工作专业化水平等建议。     

出生前混配农药暴露对雄性大鼠早期生殖发育的影响

[目的]探讨出生前暴露于氯氰菊酯和甲基对硫磷混配农药对雄性大鼠早期生殖发育的影响.[方法]Wistar孕鼠随机分为4组,从受孕1天至15天连续经口染毒(两种农药以相当于1/300、1/95、1/30LD50剂量等毒混配),对照组采用菜籽色拉油.雄性仔代出生第一天测量肛殖距离、体重、身长和尾长;10周龄每组处死10只,测定睾丸、附睾、前列腺重量,并计数睾丸每日生精量和附睾尾精子数,取血进行生殖激素促黄体生成激素(LH)、促卵泡成熟激素(FSH)、雌二醇(E2)、睾酮(T)测定.[结果]未观察到混配农药对新生雄性仔鼠肛殖距离、身长、尾长和体重的影响,各剂量组睾丸、附睾和前列腺脏器系数以及睾丸每日精子生成量和附睾尾精子数也无差异.血清睾酮(T)低剂量组高于组对照组(P＜0.05).[结论]雄性大鼠出生前暴露于甲基对硫磷和氯氰菊酯混配农药可以对血清生殖激素睾酮的水平产生干扰作用.
