B—SLIM课堂教学模式与大学英语教学

B—SLIM课堂教学模式是建立在认知论、结构主义与发展主义基础上的成功语言教学模式,并通过大量实证得出学生语言学习需要语言建构与自主学习,因而实现语言习得。文章通过对B—SLIM教学模式的主要内容介绍,结合我国大学英语教学现状分析,建议大学英语课堂教学设计应注重发挥学生的认知建构,突出学生学习的自主性;让学生参与教学过程,培养其研究性学习;转变师生角色;教学评价由终结性过渡到形成性评价,最终达到语言教学成功的目的。     

抗战时期基督教夏令儿童会初探

夏令儿童会是近代在华诸差会为养成儿童“基督化人格”。为教会造就生力军而开展的一项涉及儿童的教会工作。随着抗日战争的到来，由中华全国基督教协进会发起倡导的夏令儿童会，在中华基督教宗教教育促进会的领导推动之下，迎难而上．除每年七八两月按时照例开办之外．并在一定程度上服务于战时难童救济工作。本文以中华全国基督教协进会月刊《中华归主》为主要资料来源，通过对其中有关夏令儿童会资料的梳理，探求国难时期协进会系统下夏令儿童会的历史真相。     

基于索洛模型的区域经济增长驱动因素实证研究

在供给侧改革背景下,区域经济增长的驱动因素显著影响着区域经济的高质量和可持续发展。以索洛增长模型为基本框架,利用2003～2017年安徽省经济发展相关数据开展实证研究,测算资金投入、劳动力投入、技术进步各因素对经济增长的贡献率;同时对模型进行扩展,研究安徽省经济增长的长期驱动力量,对现期和远期的动能转换加以阐述。研究认为,现阶段资金投入仍然是安徽省经济产出的主要驱动因素,劳动力投入的经济推动效应相对较小,技术进步的驱动力量逐步提升,安徽省远期经济发展将主要依赖于技术创新驱动。安徽省应注重科技创新,进行产业结构优化调整,将技术因素融于资金、劳动供给侧,全面深化以技术为主的供给侧改革,加快经济增长动力转型。     

新农村建设“三点一面”工作体系的构建

一些发达国家的发展历程表明,在工业化、城市化进程中,都有一个新农村建设的过程,也正是这个过程推动了其经济发展的再次跨越。我国提出的社会主义新农村建设这一历史性课题,是一项长期而又复杂的系统工程。县域作为承载农村发展的前沿,是实验者,更是直接推动者。近年来,胶州市始终坚持以城乡统筹为基本思路、以城乡一体化为目标方向,探索形成了健全工作推进面、找准突破切入点、夯实经济支撑点、强化城乡统筹点的“三点一面”新农村建设工作体系,创新性地确立了新农村建设百项评价指标体系,全面推进了新农村建设,并获得了许多宝贵经验。     

论中国扩大消费需求的供给侧支撑

以消费供给来促进消费需求的上扬有着深厚的理论与实践基础,仅从需求侧探求消费需求的增长无法对现实问题给出全面解释,秉承需求侧与供给侧对接的理念才能共同拉动经济进步,从根本上推动消费需求的上涨。中国目前的消费供给面临着有效供给的不足,主要体现在高质量供给不足、高端消费供给不足、个性化消费供给不足三个方面。要提振中国消费需求,需要重视供给侧的重要作用,从提升产品质量、提高消费层次、增加个性化供给等方面进行努力。     

Case–control genome-wide joint association study using semiparametric empirical model and approximate Bayes factor

We propose a semiparametric approach for the analysis of case–control genome-wide association study. Parametric components are used to model both the conditional distribution of the case status given the covariates and the distribution of genotype counts, whereas the distribution of the covariates are modelled nonparametrically. This yields a direct and joint modelling of the case status, covariates and genotype counts, and gives a better understanding of the disease mechanism and results in more reliable conclusions. Side information, such as the disease prevalence, can be conveniently incorporated into the model by an empirical likelihood approach and leads to more efficient estimates and a powerful test in the detection of disease-associated SNPs. Profiling is used to eliminate a nuisance nonparametric component, and the resulting profile empirical likelihood estimates are shown to be consistent and asymptotically normal. For the hypothesis test on disease association, we apply the approximate Bayes factor (ABF) which is computationally simple and most desirable in genome-wide association studies where hundreds of thousands to a million genetic markers are tested. We treat the approximate Bayes factor as a hybrid Bayes factor which replaces the full data by the maximum likelihood estimates of the parameters of interest in the full model and derive it under a general setting. The deviation from Hardy–Weinberg Equilibrium (HWE) is also taken into account and the ABF for HWE using cases is shown to provide evidence of association between a disease and a genetic marker. Simulation studies and an application are further provided to illustrate the utility of the proposed methodology.     

Methods for calculating stationary distribution in linear models of time series

The article deals with methods for computing the stationary marginal distribution in linear models of time series. Two approaches are described. First, an algorithm based on approximation of solution of the corresponding integral equation is briefly reviewed. Then, we study the limit behaviour of the partial sums c ₁ η₁+c ₂ η₂+···+c _n η _n where η _i are i.i.d. random variables and c _i real constants. We generalize procedure of Haiman (1998) [Haiman, G., 1998, Upper and lower bounds for the tail of the invariant distribution of some AR(1) processes. Asymptotic Methods in Probability and Statistics, 45, 723–730.] to an arbitrary causal linear process and relax the assumptions of his result significantly. This is achieved by investigating the properties of convolution of densities.
