高等院校英语强化课程的评估体系与评估模式的构建

文章选取培正商学院的一年英语强化教改项目作为研究个案,根据(背景—输入—过程—输出CIPP)评估理论,利用质性评价和量性评价相结合的手段,对强化项目的背景和过程进行了评价。并由此构建出了一个针对高职高专院校公共外语教学的、具有自我约束并持续改进的课程评估体系。     

翻译理论新标准与语言学理论

语言学的发展一直在不断地影响着翻译理论的发展,只不过有时这种影响很间接,尼达的译学思想在中国翻译界一向占据着重要的地位,但这位大师最近宣布其观点已经发生根本变化,尼达学术观点的变化无疑会给目前译学建设带来一定的负面影响。本文着重从翻译理论的作用、翻译标准及语言学与翻译的关系三个角度对尼达翻译思想的转变加以分析;重新阐述理论在译学框架中的地位及作用,理论和实践的关系及翻译理论的意义。

西方国家反经济全球化理论述评

在当今经济全球化迅速发展的同时,反经济全球化的理论也风起云涌,主要观点有:(1)自由放任的经济全球化政策本身弊端凸显;(2)不平等的世界格局下经济全球化的发展加深了南北差距;(3)经济全球化给发达国家也带来了威胁;(4)经济全球化的实质是资本主义霸权的全球扩张。对这些观点作了系统评价。     

工业企业经济效益综合评价与分析

利用SPSS软件,对我国31个省、直辖市的大中型工业企业的总资产贡献率、成本费用利润率、资本保值增值率、流动资产周转次数、全员劳动生产率、产品销售率、资产负债率、总资产周转率、净资产收益率、销售利润率等十个经济效益指标进行了因子分析,并将这十个指标归结为盈利、销售、运营、发展等多个因子。最后,根据每个因子得分情况将所有地区归为六类,进而做出综合评价。     

Generalized additive models for location, scale and shape

Summary.  A general class of statistical models for a univariate response variable is presented which we call the generalized additive model for location, scale and shape (GAMLSS). The model assumes independent observations of the response variable y given the parameters, the explanatory variables and the values of the random effects. The distribution for the response variable in the GAMLSS can be selected from a very general family of distributions including highly skew or kurtotic continuous and discrete distributions. The systematic part of the model is expanded to allow modelling not only of the mean (or location) but also of the other parameters of the distribution of y , as parametric and/or additive nonparametric (smooth) functions of explanatory variables and/or random-effects terms. Maximum (penalized) likelihood estimation is used to fit the (non)parametric models. A Newton–Raphson or Fisher scoring algorithm is used to maximize the (penalized) likelihood. The additive terms in the model are fitted by using a backfitting algorithm. Censored data are easily incorporated into the framework. Five data sets from different fields of application are analysed to emphasize the generality of the GAMLSS class of models.     

文化生产力的崛起与发展

马克思提出的文化生产力概念包含着正确把握现代社会智能生产力的指导性原则。文化生产力的提出, 使文化知识从非独立因素变为独立因素,由潜在生产力变为现实生产力。文化生产力的高度发展对现代文明的影响是全方位的,将对旧有的生产生活方式、思维方式、价值观念、教育模式和经营管理及领导决策产生重大影响,从而改变财富的分配方式。改革开放以来,我国文化生产力有了突破性发展,但在总体水平上同发达国家的差距很大。应当强化全民的“文化生产力”意识,建立起国家的技术创新体系和知识创新体系,加大对教育和科技的投入。

Bayesian analysis of a marked point process: Application in seismic hazard assessment

Point processes are the stochastic models most suitable for describing physical phenomena that appear at irregularly spaced times, such as the earthquakes. These processes are uniquely characterized by their conditional intensity, that is, by the probability that an event will occur in the infinitesimal interval (t, t+Δt), given the history of the process up tot. The seismic phenomenon displays different behaviours on different time and size scales; in particular, the occurrence of destructive shocks over some centuries in a seismogenic region may be explained by the elastic rebound theory. This theory has inspired the so-called stress release models: their conditional intensity translates the idea that an earthquake produces a sudden decrease in the amount of strain accumulated gradually over time along a fault, and the subsequent event occurs when the stress exceeds the strength of the medium. This study has a double objective: the formulation of these models in the Bayesian framework, and the assignment to each event of a mark, that is its magnitude, modelled through a distribution that depends at timet on the stress level accumulated up to that instant. The resulting parameter space is constrained and dependent on the data, complicating Bayesian computation and analysis. We have resorted to Monte Carlo methods to solve these problems.     

信度函数在政府形象评价模型中的应用

在分析政府形象效能评价系统和信息置信度的基础上,建立了基于信度函数的政府形象评价模型。运用该函数建模分析了政府形象评估中的理念识别系统、行为识别系统、视觉识别系统、环境识别系统以及个人识别系统等五大不确定性评价问题。经过理论分析,该函数对政府形象的评估有较大的参考价值。此外,该函数也可以用于对其他类似复杂性系统的效能评估,具有普遍适用性。
