汉源县城迁复建项目管理的启示

汉源县城建设项目是移民迁复建项目,在迁建过程中存在规划调整、设计成果不衔接、擅自提高设计标准、实施与规划不一致、实施组织混乱、施工质量低劣等问题,其原因是主要领导的频繁更替使安置思路的连续性受到影响,缺乏有效的设计协调和项目管理计划,前期选择的施工队伍能力低下,监理机构工作不力等.基于上述情况,提出采用设计总承包协调各设计单位工作、提高设计质量,加强项目前期策划工作,制定切实可行的项目管理计划和实施组织计划,促进施工管理的科学化、规范化,实行施工总承包模式,简化地方政府管理难度,保证施工质量的建议.这些建议对于移民迁建中的重大项目具有普遍的借鉴意义.

Asymptotic properties of a generalized regression-type predictor of a finite population variance in probability sampling

A system of predictors for estimating a finite population variance is defined and shown to be asymptotically design-unbiased (ADU) and asymptotically design-consistent (ADC) under probability sampling. An asymptotic mean squared error (MSE) of a generalized regression-type predictor, generated from the system, is obtained. The suggested predictor attains the minimum expected variance of any design-unbiased estimator when the superpopulation model is correct. The generalized regression-type predictor and the predictor suggested by Mukhopadhyay (1990) are compared.     

和谐发展教学理念下体育实践课教案的设计

:通过对1958年以来有代表性的40份体育实践课教案的分析,发现几十年以来教案的格式、结构、教学方案设计基本不变,针对这种现象,提出了应重视开发"教案资源",把单一化、公式化、封闭性的教案设计向多样化、个性化、智力化的教案设计转变,以高效利用"教案资源"。     

Calculating the density and distribution function for the singly and doubly noncentral F

Simple, closed form saddlepoint approximations for the distribution and density of the singly and doubly noncentral F distributions are presented. Their overwhelming accuracy is demonstrated numerically using a variety of parameter values. The approximations are shown to be uniform in the right tail and the associated limitating relative error is derived. Difficulties associated with some algorithms used for exact computation of the singly noncentral F are noted.     

Sequential experimental design and response optimisation

We consider the situation where one wants to maximise a functionf(θ,x) with respect tox, with θ unknown and estimated from observationsy _k . This may correspond to the case of a regression model, where one observesy _k =f(θ,x _k )+ε _k , with ε _k some random error, or to the Bernoulli case wherey _k ∈{0, 1}, with Pr[y _k =1|θ,x _k |=f(θ,x _k ). Special attention is given to sequences given by , with an estimated value of θ obtained from (x₁, y₁),...,(x _k ,y _k ) andd _k (x) a penalty for poor estimation. Approximately optimal rules are suggested in the linear regression case with a finite horizon, where one wants to maximize ∑ _i=1 ^N w _i f(θ, x _i ) with {w _i } a weighting sequence. Various examples are presented, with a comparison with a Polya urn design and an up-and-down method for a binary response problem.

Demand and supply network design scope for personalized manufacturing

This paper first presents personalizing and personalized manufacturing as a means for firms to meet the rising challenge, faced by a large variety of manufacturers, to offer innovative highly personalized products with short and reliable delivery delays in a digital and global economy that is highly turbulent and competitive. It positions personalizing versus the current trend of mass customising. It characterizes complementary types of personalizing and highlights the key elements for their successful implementation from a demand and supply network perspective. Finally, it illustrates the scope and addresses how personalizing affects the design of the demand and supply network, emphasizing the scope of this design influence, the variety of options for each element of the network, and the interrelationships between the design decisions.
