以人为本的政府管理的价值回归及其模式选择   总被引：6，自引：0，他引：6  

汪大海  唐德龙 《教学与研究》2005,4(3):20-26

以人为本的政府管理思想及其价值取向源于人类对经济、政治、社会、自然以及自身发展的认识,这些认识主要表现在以神为本、以君为本、以官为本、以民为本、以物为本、人本主义、个人本位主义、人类中心主义等思想及其价值演变之中。而在“由官到民”与“由物到人”双重转变过程的交汇点,现代政府管理的价值终于回归于“以人为本”,并在此基础上形成了一种可持续与可治理的现代政府管理模式。这是一种崭新的政府管理的价值观、方法论和模式选择,也是渐进式改革的新动力。  相似文献

Bayesian Quantile Structural Equation Models     

Yifan Wang  Xiang-Nan Feng 《Structural equation modeling》2016,23(2):246-258

Structural equation modeling is a common multivariate technique for the assessment of the interrelationships among latent variables. Structural equation models have been extensively applied to behavioral, medical, and social sciences. Basic structural equation models consist of a measurement equation for characterizing latent variables through multiple observed variables and a mean regression-type structural equation for investigating how explanatory latent variables influence outcomes of interest. However, the conventional structural equation does not provide a comprehensive analysis of the relationship between latent variables. In this article, we introduce the quantile regression method into structural equation models to assess the conditional quantile of the outcome latent variable given the explanatory latent variables and covariates. The estimation is conducted in a Bayesian framework with Markov Chain Monte Carlo algorithm. The posterior inference is performed with the help of asymmetric Laplace distribution. A simulation shows that the proposed method performs satisfactorily. An application to a study of chronic kidney disease is presented.  相似文献   

Data-driven facial animation based on manifold Bayesian regression   总被引：1，自引：0，他引：1  

WANG Yu-shun ZHUANG Yue-ting WU Fei 《浙江大学学报(A卷英文版)》2006,7(4):556-563

INTRODUCTION Realistic facial animation is highly important in the computer graphics field as it is an essential facility for human-computer interface and virtual reality and is also a difficult task because there are so many non-rigid motions besides rigid motion of heads as expression changes. Instead of modelling all the complicated facial motions, data-driven facial ani- mation just exploits facial motion data captured in real scenes. Most motion capture systems rely upon the placement…  相似文献   

The truth,but not yet: avoiding naïve skepticism via explicit communication of metadisciplinary aims     

Jake Wright 《Teaching in Higher Education》2019,24(3):361-377

ABSTRACT

Introductory students regularly endorse naïve skepticism – unsupported or uncritical doubt about the existence and universality of truth – for a variety of reasons. Though some of the reasons for students’ skepticism can be traced back to the student – for example, a desire to avoid engaging with controversial material or a desire to avoid offense – naïve skepticism is also the result of how introductory courses are taught, deemphasizing truth to promote students’ abilities to develop basic disciplinary skills. While this strategy has a number of pedagogical benefits, it prevents students in early stages of intellectual development from understanding truth as a threshold concept. I argue that we can make progress against naïve skepticism by clearly discussing how metadisciplinary aims differ at the disciplinary and course levels in a way that is meaningful, reinforced, and accessible.  相似文献   

Nearing world-class: Singapore’s two universities in QSWUR 2015/16     

Kaycheng Soh 《Journal of Higher Education Policy & Management》2016,38(1):78-87

Many universities strive to become world-class and two of Singapore’s universities are almost there, being ranked 12th and 13th in the QSWUR 2015/16. This study looked into the details of indicator rankings and found that the two universities are comparable to those in the top 10 universities in the same ranking in practically all indicators with the exception of Citations. Further analysis of the data of the 58 highest ranking universities with complete data revealed discrepancies in the assigned and attained indicator weights. Moreover, the Academic and Citations categories were not able to be used in stepwise regression calculations. These indicate that the computed Overall result is not what the ranker intended it to be and needs re-interpretation. If rankings are not anchored in statistical ground, discussions on rankings are at the abstract and verbal level, similar to discourses on alchemy (faith) vis-a-vis chemistry (facts).  相似文献

认知研究的回归－从行为主义到认知心理学     

廖全明 《涪陵师范学院学报》2002,18(5):57-59

全部心理学研究方向发展的线索都可以从行为主义到认知心理学的发展历程中找到，这个研究方向发展的线索就是认知研究的回归。从研究对象、理论基础、研究方法和理论观点等四个方面进行分析，可以看出认知研究的回归反映了心理学研究方向的发展。  相似文献
