The innovation research of financial early-warning index measurement

The period economic fluctuation is vital for an enterprise to exist and further develop,it directly affect the enterprise financial health.So,it is significant to build up financial early-warning index and measure the warning condition that the enterprise faces and take the effective measures to eliminate. We criticize Altman's Z calculating model and build up some new indexes for enterprise financial early-warning condition measuring and making sound decision.

试论效用价值论的价值判断和客观基础

效用价值论作为一种价值理论,必然包含有价值判断,这种判断就是认为资本主义生产方式是合理的和永恒的.这决定了它不可能是科学的理论,但却并不能因此而否认它所包含的科学成分,它的客观基础在于效用与价值之间存在的联系.

动态等值论在文学翻译中的应用

美国的尤金·奈达博士(Dr.Eugene A. Nida)的动态等值论(Dynamic Equivalence)被许多学者推崇为评判译文质量优劣的标准以及翻译所追求的最终目标.在运用奈达的"动态等值"论来指导文学翻译时,应注意的问题是,译文如果要准确传递原文信息就要充分体现原作者的美学意图,这样才能使译文受众获得和原文受众基本一致的感觉.

Fecundity of the blood-feeding insectRhodnius prolixus increases in successive periods of egg production

The fecundity of the blood-feeding insect,Rhodnius prolixus, was observed to increase in successive periods of egg production, each period being triggered by a single large blood meal. As previously published, the fecundity of mated animals was significantly higher than that of unmated animals for the first period of egg production. For a second period of egg production, fecundity increased significantly in both mated and unmated animals. By the fourth period, fecundity had returned to first-feed values for mated animals, but remained high for unmated animals, and the fecundity of mated and unmated animals was not significantly different. Thus, during successive periods of egg production, the processes which maintain fecundity of unmated animals below that of mated animals are overcome.
