当代高校院系资料室的困境与发展走向

高校院系资料室在高校创新发展和计算机网络技术的挑战面前,反应迟钝,发展滞后。围绕着高校院系资料室的发展走向。大家提出了改革发展说、分馆说和撤销并入说三种观点,提出高校院系资料室发展走向是一个综合性的问题,只有实事求是,详细调查,深入研究,科学确定发展模式。才能走出困境,推动高校教学科研的发展。     

Ordinary least squares estimation of the functional errors-in-variables model with trended data:some monte carlo evidence

This note summarizes some Monte Carlo experiments that were designed to investigate the finite sample relevance of the asymptotic normality and efficiency of OLS in the errors-in-variables model with trended data. The experiments show that the normal approximation is not very satisfactory for sample size up to T=400, but that OLS is quite efficient relative to competing estimators when there is a trend in the exogenous variables of the model.     

A Method for Projecting Age-Specific Mortality Rates for Certain Causes of Death

A method is presented for projecting mortality rates for certain causes on the basis of observed rates during past years. This method arose from a study of trends in age-specific mortality rates for respiratory cancers, and for heuristic purposes it is shown how the method can be developed from certain theories of cancer induction. However, the method is applicable in the more common situation in which the underlying physical processes cannot be modeled with any confidence but the mortality rates are approximable over short time intervals by functions of the form a exp (bt) , where b may vary in a continuous, predictable fashion as the time interval is varied. It appears from applications to historical data that this projection method is in some cases a substantial improvement over conventional curve-fitting methods and often uncovers trends which are not apparent from observed data.     

科学发展之“科学性”探析

科学范畴所蕴含的工具理性和价值理性启示我们,作为对科学发展之根本特征的科学性的理解需要从真善美三个方面入手。真、善、美分别代表着科学发展的三大方面,它们是集科学发展的规律性或必然性、功利性或目的性、观赏性或情感性于一体的基本要素。一种发展,只有具备了真善美的要素或属性,才能属于科学的发展。
