中国船级社在大连建设东北亚国际航运中心中的作用及自身发展

在大连建设东北亚国际航运中心的过程中 ,中国船级社应在大连的航运业、修造船业、港口基础设施建设、现代物流中心建设、软环境建设、腹地经济发展等方面发挥积极作用 ,同时应通过扩大新建船舶检验市场份额、大力发展海洋工程及与其相关的检验业务、积极开拓陆上产业等措施加快自身的发展。     

语调变体解构

正确把握语调变体是言语交际成败的关键;口语中不同语调的使用表述了说话人不同的思想感情和态度.也正是这种语用语调的变异导致了语义理解和思想表达的细微差别,差之毫厘,谬以千里.本文从语调功能,常规语调运用及语调变体三个角度,以翔实的例句分析,对英语语调变体进行解构.

Quadratic estimators of covariance components in a multivariate mixed linear model

It is known that the Henderson Method III (Biometrics 9:226–252, 1953) is of special interest for the mixed linear models because the estimators of the variance components are unaffected by the parameters of the fixed factor (or factors). This article deals with generalizations and minor extensions of the results obtained for the univariate linear models. A MANOVA mixed model is presented in a convenient form and the covariance components estimators are given on finite dimensional linear spaces. The results use both the usual parametric representations and the coordinate-free approach of Kruskal (Ann Math Statist 39:70–75, 1968) and Eaton (Ann Math Statist 41:528–538, 1970). The normal equations are generalized and it is given a necessary and sufficient condition for the existence of quadratic unbiased estimators for covariance components in the considered model.     

Modelling heterogeneous space–time occurrences of earthquakes and its residual analysis

Summary. Earthquake intensities are modelled as a function of previous activity whose specific form is based on established empirical laws in seismology, but whose parameter values can vary from place to place. This model is used for characterizing regional features of seismic activities in and around Japan, and also for exploring regions where the actual seismicity rate systematically deviates from that of the modelled rate.     

Consumption and Saving Behavior of Older and Younger Baby Boomers in Korea

The 1998 Korean Survey of Family Income and Expenditures was used to examine the overall consumption and saving behavior of Korean baby boomers and compared the differences in consumption and saving behavior between older and younger boomers. The t -test results indicated that the younger boomers allocated a significantly higher percentage of their expenditures on food away from home, household appliances, transportation and communication than did the older boomers, whereas the older boomers spent higher amounts and allocated larger budget shares on their children's education than did the younger boomers. The results of Ordinary Least-Squares (OLS) regression analysis showed that, holding other factors constant, older boomers not only spent significantly more in the total consumption expenditures and education expenditures, but older boomers also saved significantly less than did younger boomers.
