采用问卷调查的方法,以新疆大学国际文化交流学院中亚留学生为调查样本,对其汉语学习需求进行了探索性实证研究,得出以下主要结论:中亚留学生汉语水平的目标主要分为初级和中高级两个层次,应细化学生需求,提供区别性教学对策。中亚留学生汉语学习时间较短,应采用速成强化教学模式。汉字占用了过多的学习资源,应采用“语文分开、集中识字”的教学模式。中亚留学生汉语学习符合二语习得一般规律,应加强泛读课型和习得性教学活动的研究。新疆对外汉语教学与中亚留学生的目标需求之间存在着差距,应加强教学资源的建设。 相似文献

中部崛起战略将是继东部大发展、西部大开发、东北大振兴之后的又一个重要发展战略,将对促进区域经济协调发展起重要的作用。但是目前,中部各省纷纷表示要主导中部的发展,要起“中部龙头”的作用,要率先崛起。本文用计量经济学有关的知识,分析了中部六省的经济梯度格局发展概况,认为中部六省应作为一个整体板块来崛起,应该加强合作与协调发展,并提出了相应的合作战略。 相似文献

目前,我国中部地区在全国经济发展格局中呈现出发展水平低于东部,发展速度慢于西部的“塌陷”态势。针对这一情况,中央把中部崛起作为一个国家经济发展的重大战略提出来。中部地区要发展必须彻底改变传统经济的发展模式,而采用循环经济发展模式。通过对中部地区的经济社会现状进行分析,指出其发展循环经济的迫切性;得出其发展循环经济的相应对策。 相似文献

On distribution-weighted partial least squares with diverging number of highly correlated predictors
Li-Ping Zhu Li-Xing Zhu 《Journal of the Royal Statistical Society. Series B, Statistical methodology》2009,71(2):525-548
Summary. Because highly correlated data arise from many scientific fields, we investigate parameter estimation in a semiparametric regression model with diverging number of predictors that are highly correlated. For this, we first develop a distribution-weighted least squares estimator that can recover directions in the central subspace, then use the distribution-weighted least squares estimator as a seed vector and project it onto a Krylov space by partial least squares to avoid computing the inverse of the covariance of predictors. Thus, distrbution-weighted partial least squares can handle the cases with high dimensional and highly correlated predictors. Furthermore, we also suggest an iterative algorithm for obtaining a better initial value before implementing partial least squares. For theoretical investigation, we obtain strong consistency and asymptotic normality when the dimension p of predictors is of convergence rate O { n 1/2 / log ( n )} and o ( n 1/3 ) respectively where n is the sample size. When there are no other constraints on the covariance of predictors, the rates n 1/2 and n 1/3 are optimal. We also propose a Bayesian information criterion type of criterion to estimate the dimension of the Krylov space in the partial least squares procedure. Illustrative examples with a real data set and comprehensive simulations demonstrate that the method is robust to non-ellipticity and works well even in 'small n –large p ' problems. 相似文献

The responses obtained from response surface designs that are run sequentially often exhibit serial correlation or time trends. The order in which the runs of the design are performed then has an impact on the precision of the parameter estimators. This article proposes the use of a variable-neighbourhood search algorithm to compute run orders that guarantee a precise estimation of the effects of the experimental factors. The importance of using good run orders is demonstrated by seeking D-optimal run orders for a central composite design in the presence of an AR(1) autocorrelation pattern. 相似文献

Conflicts in urban fringe in the transformation era: An examination of performance of the metropolitan growth management in Beijing 总被引:3,自引:1,他引:2
The performances of urban growth management are often criticized because their original objectives are frequently inconsistent with local development facts. Underlying the many reasons for this are the political and institutional contexts that influence policy-making and development activities. The urban fringe, a zone is managed to against urban sprawl in many countries, represents the conflicts between urban management system and local development resulting from political transformation. This study examines the case of decentralised-concentration strategy, one of the most important metropolitan growth management in Beijing since the 1990s, and sheds some lights on the performance of the growth management in the transformation context. The results suggest that the aims of municipal growth management to concentrate developments in urban fringe have partly been achieved through actual local developments; however, some unexpected and illegal local developments outside the planned areas are counterproductive from the perspective of municipal growth management. The performance of the present growth management is being challenged by new trends towards political decentralisation and locally fiscal responsibilities. In the interest of future policymaking, the dominant central planning system in Beijing should take these decentralisation trends into growth management account, compared with the great progress in decentralisation in economy system. The urban policy needs to shift from the dictatorial manner and put more efforts into creating a harmonious relationship between municipal growth management and actual local demands on development. 相似文献

Ferenc Miszlivetz 《Transition Studies Review》2009,15(4):623-635
The economic, political and social transition processes of the last two decades, far from being in harmony, clearly have a
detrimental rather than an enriching influence on each other. These processes will never become harmonised just by themselves
in a natural fashion. The worst obstacle of a successful transformation is that the chief actors, such as the government,
the market and the representatives of the society. The Prince, the Merchant and the Citizen do not show the necessary commitment,
competence and determination to create a new, effective type of partnership. This is a challenge which urgently demands answers
on all levels of governance, economic and social life. This must be done in the frames of local communities, and on the regional,
the European and the global levels. Nearly twenty years after the political turnabout, Hungary now needs a new social contract
and must lay down the ethical, political, institutional and intellectual foundations for its twenty-first century democracy.

In the 2006 French housing survey, information is collected on many aspects of housing to describe the housing stock in France and the housing conditions of French households. The basic national sample results from a multistage sampling design. Complementary samples were selected to perform accurate estimations for socio-demographic domains. Some French regions proceeded to a regional and local extension of the national sample. The variance is estimated for a region with a regional and local extension of the basic national sample. 相似文献

There are times when entire populations of certain countries have had to readjust their lives and economic strategies as all of society is under transition. Post-Soviet Central Asia underwent this period after 1991. During times of transition, there are always people that tend to be able to make use of the new uncertainties, even at the risk of entering legal grey areas. Here new social groups emerge, ethnic origin becomes relevant and new kinship ties are made. These transformation periods are often short and provide limited opportunities for analysing the strategies of those pioneers that I call Kairos economists. They often act only in cooperation with residents of the border and with duty customs and security personnel. This article analyses this special economy with the help of case studies that have been observed during the transformation period from the Soviet to an independent Central Asia. 相似文献
