论市场机制在提高高等教育资源利用效率中的作用

良好的运行机制是提高高等教育资源利用效率的必要条件。普通高等教育的非营利性、外在性等特点决定了市场机制不能在高等教育领域发挥基础性调节作用，高等教育不能市场化。但高等教育领域可以引入市场机制，在生源市场、资金市场、劳动力市场等引入市场机制，有利于提高高等教育资源利用效率。     

The Current State of China's Freshwater Resources and Related Suggestions

China has many lakes, marshlands and rivers. Due to their uneven geographical distribution and varied degrees of salinity, their exploitable freshwater resources are limited. In the wake of the highspeed growth of national economy in recent years, human infringement upon their natural settings has been increasingly intense, leading to the degeneration of China's lacustrine ecosystems and the degradation of their surrounding environments. Lakes are shrinking and becoming more saline. In arid and semi-arid inland areas, some of them have even disappeared. In addition, lake water pollution and eutrophication in densely populated areas are getting worse, resulting in serious water shortages in some places. Silt deposition in lake basins, water surface shrinkage caused by hectic and irrational reclamation for farmland, the prevalence of flooding and water-logging calamities and ecosystem depletion caused by predatory exploitation of fishery resources, all of these have become restrictive factors in regional sustainable development. The author of this article suggests measures for the protection and sustainable exploitation of limnetic settings in China.     

基于上证30及深圳成指的我国股票市场“羊群行为”的实证研究

本文采用CSAD（横截面收益绝对差）方法，对我国股票市场是否存在“羊群行为”进行了实证检验。结果发现：在上涨行情中，我国深圳证券市场与上海证券市场均不存在“羊群行为”；但在下跌行情中，深圳证券市场与上海证券市场均存在“羊群行为”，且深圳证券市场比上海证券市场具有更多的“羊群行为”。对产生“羊群行为”的原因，作者进行了简要分析。     

基于CRM的企业间的客户竞争研究

传统客户竞争模型存在不足,不能用于客户关系管理CRM下的客户竞争。为从理论上深入研究CRM下的客户竞争,建立了CRM下的企业间客户竞争的理论模型。在这个模型中,首次包含了CRM中客户对不同企业品牌的偏好因素、客户关系周期长度和产品定价模式对客户竞争的影响。通过对竞争模型的分析,得到了CRM下竞争企业的定价下限、发生转移的客户的偏好特征模式和企业的市场份额函数等客户竞争结果。     

针刀松解法治疗膝骨关节炎临床对照研究

目的：通过与电针治疗膝骨关节炎的疗效进行对比，观察针刀对膝骨关节炎患者各项指标的影响以及总体疗效如何。方法：采用随机、对照的方法，试验组24例，采用针刀治疗；对照组24例，采用电针治疗。对比两组临床疗效。结果：（1）经过3周的治疗，电针组和针刀组均取得了一定的近期效果，与治疗前相比各项指标均有显著改善，两组的有效率比较无显著差异。（2）疗效的趋向性与治疗方法有关，针刀组更加趋向于临床治愈（P=0.04）。（3）两组患者治疗前后自身指标分值比较：疼痛、关节僵硬、生理功能、压痛、肿胀、关节活动度均有下降，具有统计学意义；针刀组与电针组治疗后各指标分值比较，疼痛、关节僵硬、生理功能、压痛、肿胀均无统计学意义。针刀组患者治疗后关节活动度显著优于电针组。结论：通过上述研究认为针刀治疗膝骨关节炎近期疗效良好，值得进一步深入研究。

Building a just world: the effects of service-learning on social justice beliefs of Chinese college students

This study aimed to examine the effects of different service experiences on the social justice beliefs of 60 Chinese college students with mixed methods. The quantitative results indicated that the participants in two service groups (i.e. for at-risk adolescents and adolescents with cerebral palsy) demonstrated a more significant promotion of social justice beliefs than their peers in non-service group. A qualitative analysis provided evidence of the mechanism underlying service-learning, as well as different service experiences affecting on students’ social justice beliefs. Finally, the implications for implementing service-learning and realizing social justice goals in China were discussed.
