论当代大学生活动道德教育模式的实施结构

道德的形成与发展有其自身的规律,要提高当代大学生德育的有效性,就必须结合并遵循当代大学生主体道德意识发展的特点和德育发展的规律,才能实现这一目标。本文从当代大学生主体德育发展的特点和规律出发,对活动道德教育模式的内涵、确立的依据、实施结构等诸方面对该模式进行剖析,致力于提高当代大学生德育的有效性研究。     

近代河南集市研究再思考

近代集市的发展不仅表现为数量方面的增加,也有集市数量不变而集市承载量增加的情况;考察集市分布密度以耕地面积为基础更有可比性,而且开市率的高低主要是人们传统习惯、人口规模、集市密度、商品化程度、经济发展状况等因素综合作用的结果,其中传统习惯对开市率的影响较大。     

面向基础教育课程改革的教师教育职前培养模式探析

在师范教育转型的过程中，师范院校应转变传统的人才培养观念。针对基础教育课程改革，积极进行教师教育职前培养模式创新探索，培养具有综合的学科知识和专业化教育水平的新型教师，适应基础教育课程改革的需要。     

养老保险体系的两种模式与社会经济因素关系比较分析

本文分析了现收现付和基金积累两种不同养老保险模式与人口老龄化、社会经济增长、通货膨胀、储蓄等社会经济因素之间的关系。经济的增长情况以不同的方式对现收现付模式和基金积累模式产生影响:对现收现付模式来说,如果经济增长缓慢,未来就业者的养老金负担就会增加,其效果与老龄人口在总人口中的比重增大一样;对于基金积累模式而言,如果经济的增长缓慢,那么在长时期内,利率就会处于一个相对较低的水平,这是不利于养老基金的有效增值,未来退休者的养老金收益就会减少。与现收现付模式相比,基金积累模式能带来一个更高的储蓄水平。

冠状动脉收缩期受压持续到舒张期的模拟实验分析

利用研制的心肌桥模拟装置,对冠状动脉受压迫状态建立了圆形收缩的实验模型,进行了冠状动脉受心肌桥压迫持续到舒张期情况下的血压和流量模拟实验.实验研究表明,冠状动脉面积收缩接近到原来的20%时,远段收缩压迅速与近段收缩压分离;当冠状动脉面积收缩到小于原来的20%时,近段收缩压迅速上升,远段压力从不稳定状态迅速过渡到收缩压呈反向分布状态.心率和近段血压范围不变时,流量随着收缩程度的增加而增加.     

BATHTUB-TYPE CURVES IN RELIABILITY AND BEYOND

Finding optimal, or at least good, maintenance and repair policies is crucial in reliability engineering. Likewise, describing life phases of human mortality is important when determining social policy or insurance premiums. In these tasks, one searches for distributions to fit data and then makes inferences about the population(s). In the present paper, we focus on bathtub‐type distributions and provide a view of certain problems, methods and solutions, and a few challenges, that can be encountered in reliability engineering, survival analysis, demography and actuarial science.     

Stochastic Modelling of Times to Temperature for Furnaces Supplying Titanium Blooms to a Rolling Mill at TIMET

In conjunction with TIMET at Waunarlwydd (Swansea, UK) a model has been developed that will optimise the scheduling of various blooms to their eight furnaces so as to minimise the time taken to roll these blooms into the finished mill products. This production scheduling model requires reliable data on times taken for the various furnaces that heat the slabs and blooms to reach the temperatures required for rolling. These times to temperature are stochastic in nature and this paper identifies the distributional form for these times using the generalised F distribution as a modelling framework. The times to temperature were found to be similarly distributed over all furnaces. The identified distributional forms were incorporated into the scheduling model to optimise a particular campaign that was run at TIMET Swansea. Amongst other conclusion it was found that, compared to the actual campaign, the model produced a schedule that reduced the makespan by some 35%.     

武汉市板块经济模式研究

根据武汉经济的地域分布特征,武汉板块经济发展模式分两级,第一级分三大板块(大汉口、大武昌、大汉阳),第二级在大板块内细分若干基础板块。武汉城市发展的过程和方向应为:通过基础板块质量和数量的增长,促进经济实力增强和城市空间扩张,三大板块鼎足而立,形成城市群。     

Loss functions for estimation of extrema with an application to disease mapping

It is often of interest to find the maximum or near maxima among a set of vector‐valued parameters in a statistical model; in the case of disease mapping, for example, these correspond to relative‐risk “hotspots” where public‐health intervention may be needed. The general problem is one of estimating nonlinear functions of the ensemble of relative risks, but biased estimates result if posterior means are simply substituted into these nonlinear functions. The authors obtain better estimates of extrema from a new, weighted ranks squared error loss function. The derivation of these Bayes estimators assumes a hidden‐Markov random‐field model for relative risks, and their behaviour is illustrated with real and simulated data.
