就当下艺术现状,尤其是架上艺术危机的分析,展开对绘画思想性的深刻思索,并通过对绘画与现代视觉传播媒介相互转译实验探讨,求取两者的不同所在,进而反映笔者对艺术现状的感知焦虑,以期在艺术的纯粹思维与纯粹摹写之间划定一个合理的空间,亦即确立纯艺术领域,用以对抗艺术消亡论观点.  相似文献

文章以我国A股市场上市公司为研究对象,实证研究了债务融资对过度投资行为的抑制作用.研究发现:我国上市公司普遍存在着严重的过度投资现象,债务融资及其构成特征整体上并未对公司的过度投资行为起到抑制作用.通过进一步按最终控制人性质分组检验发现,债务融资比例与银行借款在国有控股公司不但没起到抑制过度投资行为的作用,反而还恶化了公司的过度投资行为,债务融资比例与银行借款在非国有控股公司中起到了制约过度投资的作用,商业信用和长短期债务在国有与非国有控股公司中仍没起到制约公司过度投资行为的作用.  相似文献

本文依据对江苏、浙江两省6个县343户三峡外迁农村移民的调查数据,分析了相对集中与完全分散这两种不同的安置方式,以及由此所形成的两种不同的人际交往状况对外迁移民社会适应的影响。研究发现,从总体上看,移民在安置地的人际交往状况对移民的社会适应的影响十分显著。无论是移民之间的交往、还是移民与当地居民之间的交往,都会大大增强移民融入当地社会的程度。  相似文献

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.  相似文献

Many organizational change projects fail — despite a well thought out concept, professional project management and a binding implementation timetable. The reason why the expected success doesn’t materialize often lies with the missing maintenance. Once the project is officially completed and the client and project manager withdraw, the manner in which the organization will take up these changes is seldom systematically dealt with. Difficulties often arise when no discrete stabilizing measures are planned. We have derived four central action areas which will be clarified by way of practical examples. It will also be shown what is important to pay attention to in the stabilization phase so that a lasting success of the organizational change project can be ensured.  相似文献

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.  相似文献

We examine the labor-cost savings associated with privatization by comparing earnings and employment trends of public and private sector refuse workers. Findings suggest that high union earnings for workers in the public sector are a source of labor-cost savings in the refuse industry. Evidence on job changers does not indicate that earnings for this group of workers are a compensating differential. Metropolitan area employment findings suggest that municipalities are less likely to use union refuse workers in the public sector when a relatively small percentage of area residents belong to a union. The authors thank Jacqueline Agesa, Keith Bender, Maria Crawford, and Richard Perlman for valuable suggestions. Research assistance from Eric Blackburn is greatly appreciated.  相似文献
