中国城市化进程效率估算及影响因素分析

本文基于2008—2012年中国285个地级市的数据,运用双边随机前沿模型测算了中国城市化进程的前沿水平以及实际水平相对前沿水平的偏离程度。结果发现,下偏效应大于上偏效应,即中国城市化进程整体表现为滞后,并且发现投资作用和政府作用在影响城市化进程中的表现为负向,另外城市化进程也表现出地区间的不平衡。最后根据本文的发现,提出相应的建议。     

县域经济竞争力的评价与分析

县域经济综合竞争力评价的对象是县域社会经济发展的整体状况,评价方法是综合性的,评价必须准确可靠,兼顾适用性和动态性.评价指标体系应遵循完备性、可比性、代表性、可行性等原则,选取能反映县域经济发展水平、发展活力和发展潜力的指标.采用综合因子分析方法,对安徽省2004年各县域经济27个指标进行评价分析,发现安徽省县域经济竞争力整体偏弱.     

中国旅游服务贸易竞争力的影响因素分析

改革开放以来,我国旅游服务贸易保持了快速、健康的发展,中国旅游服务贸易竞争力越来越强,但与世界旅游强国相比仍有很大差距.实证分析的结果表明:我国旅行社数量对提高旅游服务贸易竞争力有促进作用.旅游交通对我国旅游出口收入有显著影响,其影响力要大于旅游产业组织的影响.我国的旅游人力资源状况对于旅游服务贸易竞争力的影响不显著.

由情感因素看教师角色的转换

情感因素在现代教育特别是现代外语教育中的地位越来越突出.积极情感可显著提升教学质量,积极情感的养成需要教师对其角色进行调整.具体来讲,教师要通过尊重学生的个性化选择、以诚相待和培养学生自信心等方法,实现自身由"讲师"向"导师"的角色转换.     

Bayesian t-tests for correlations and partial correlations

In this paper, we develop Bayes factor based testing procedures for the presence of a correlation or a partial correlation. The proposed Bayesian tests are obtained by restricting the class of the alternative hypotheses to maximize the probability of rejecting the null hypothesis when the Bayes factor is larger than a specified threshold. It turns out that they depend simply on the frequentist t-statistics with the associated critical values and can thus be easily calculated by using a spreadsheet in Excel and in fact by just adding one more step after one has performed the frequentist correlation tests. In addition, they are able to yield an identical decision with the frequentist paradigm, provided that the evidence threshold of the Bayesian tests is determined by the significance level of the frequentist paradigm. We illustrate the performance of the proposed procedures through simulated and real-data examples.

Asymptotic Bias in Parameter Estimation of AR-Processes Using Recursive Least Squares with Exponential Forgetting

The recursive least squares technique is often extended with exponential forgetting as a tool for parameter estimation in time-varying systems. The distribution of the resulting parameter estimates is, however, unknown when the forgetting factor is less than one. In this paper an approximative expression for bias of the recursively obtained parameter estimates in a time-invariant AR( n_a ) process with arbitrary noise is given, showing that the bias is non-zero and giving bounds on the approximation errors. Simulations confirm the approximation expressions.     

Values and happiness among Asian adolescents: a cross-national study

Despite policy efforts to increase adolescent happiness, their impact has been unsatisfactory. Their limited impact may be rooted from a discrepancy between values that adolescents pursued and those that the policies were based on. To provide policy implications, our study aims to identify prevailing values for South Korean, Japanese, and Chinese adolescents and to examine the relationship between the values and self-rated happiness (SRH). A cross-sectional study was conducted using survey data collected on approximately 2000 middle and high school students (7th to 12th school grade) from each country in 2008. Firstly, an explanatory factor analysis was conducted to identify salient adolescent values from each country. Subsequently, a multiple logistic regression analysis was conducted for each population group to examine the relationship between the identified values and adolescent SRH after controlling for sociodemographic characteristics. We found that benevolence and altruism were positively associated with adolescent SRH in all three population groups. Patriarchy was associated with SRH positively in Chinese yet inversely in Japanese. Success pursuit was inversely associated with SRH in Korean. Policy efforts based on values of communities or social harmony may benefit adolescents’ SRH in these three countries.
