Based on some longitudinal studies of private tutoring in twelve cities, towns, municipalities and provinces of China, the paper endeavours to depict demand intensity, articulate market parameters and reflect on policy responses towards the demand-supply mechanism of the vast shadowy educational phenomena at primary and secondary levels. Such educational phenomena are so hidden that there is a complete lack of official statistical figures in measuring the full scale of tutoring and identifying tutors in some cases. In Hong Kong and Macao, parents and their schooling children take up responsibilities to consume various types of tutoring without state intervention into quality assurance. In Mainland China, local ministries of education prohibit home tutoring delivered by daytime teachers to their daytime students whilst take a laissez-faire approach towards mass tutorials that run in private business sphere. Lastly, a multi-level societal movement framework is recommended with strategic action plans in school practitioners’ and policy-makers’ perspectives for effectively monitoring or hampering the growth of such shadowy educational phenomena in China.  相似文献

Objective: This study was designed to detect the changes of serum soluble Fas (sFas) levels in patients with locally advanced unresectable rectal cancer (LAURC),and to explore its prognostic value of response.Methods: Soluble samples were obtained from LAURC subjects,treated by concurrent chemoradiotherapy,before treatment and one month after treatment.Healthy donor serum samples were used as controls.sFas concentration was measured by enzyme-linked immunosorbent assay (ELISA).Results: The sFas levels before treatment and one month after treatment were both significantly higher in LAURC subjects than in healthy controls [(8.79±1.39) and (7.74±1.32) vs.(5.53±1.13) ng/L,P0.01].The sFas levels before treatment and one month after treatment were significantly lower in the response group (complete and partial responses) than in the non-response group (stable and progressive diseases) [(8.50±1.25) vs.(10.17±1.26) ng/L,P0.01 and (7.50±1.24) vs.(8.90±1.13) ng/L,P0.01,respectively].The one-year survival rate was 54.2% and 82.6% in those with sFas levels 8.79 ng/L and 8.79 ng/L before treatment (P0.02),respectively,50.0% and 87.0% in those with sFas levels 7.74 ng/L and 7.74 ng/L one month after treatment (P0.01),respectively.Conclusions: The sFas level is higher in LAURC subjects than in healthy controls.Concurrent chemoradiotherapy can reduce sFas levels in LAURC patients.The monitoring of sFas may provide prognostic information for LAURC patients.  相似文献

Research on work life and job satisfaction of university professors is becoming an important research issue in the field of higher education. This study used questionnaires administered to 1 770 teachers from different levels, types, and academic fields of Chinese universities to investigate job satisfaction among university professors and the relationship between job satisfaction of university professors and the organizational characteristics of the university. The job satisfaction of Chinese university professors includes six dimensions: career development and school management, teaching and research services, salary, benefits and logistical services, professional reputation, teaching and research facilities, and the work itself. The overall job satisfaction levels are close to average, with salary and benefits receiving the lowest level of satisfaction. The organizational characteristics of universities, such as school type, school level, academic field, organizational climate, evaluation orientation, and school management, all have significant effects on the overall job satisfaction of university professors. The organizational climate and school level affect all six dimensions of job satisfaction among university professors.  相似文献

IPv6通过EUI-64实现无状态地址自配置的同时也带来用户隐私问题。为此,IETF又引入RFC3041标准以产生有特定时效的无状态随机IPv6地址,提高用户的安全性,但这种无状态随机自配置地址也给IPV6包分类及网络扫描等算法的优化设计带来新的困扰。文章通过熵理论对真实IPv6地址进行随机性分析,并通过逾10万样本数据的随机测度计算后发现:RFC3041产生的IPv6地址具有固定比特恒为0的随机特性。  相似文献

Nowadays, online forums have become a useful tool for knowledge management in Web-based technology. This study proposes a social recommender system which generates discussion thread and expert recommendations based on semantic similarity, profession and reliability, social intimacy and popularity, and social network-based Markov Chain (SNMC) models for knowledge sharing in online forum communities. The advantage of the proposed mechanism is its relatively comprehensive consideration of the aspects of knowledge sharing. Accordingly, results of our experiments show that with the support of the proposed recommendation mechanism, requesters in forums can easily find similar discussion threads to avoid spamming the same discussion. In addition, if the requesters cannot find qualified discussion threads, this mechanism provides a relatively efficient and active way to find the appropriate experts.  相似文献
