The assessment of tumour response to treatment

Summary.  A parsimonious model for treated tumours is developed as a continuation of our previous work on regrowth curve theory. The statistical model belongs to the family of marginal non-linear models since the only linear parameters of the model are tumour specific and random facilitating parameter estimation. An important feature of the model is that it enables the estimation of the fraction of cancer cells surviving the treatment in vivo having easy-to-obtain longitudinal measurements of tumour volume. We compare several methods of estimation, including Lindstrom–Bates, iterated reweighted least squares and maximum likelihood. The last two methods are computed via the total estimating equations approach and variance least squares. The theory is illustrated with a photodynamic tumour therapy example.     

家庭式迁移女性农民工劳动供给行为研究

随着城市化的不断推进,家庭式迁移已经成为农民工流动的重要模式。家庭式迁移的女性农民工需要同时扮演雇佣劳动者和家务主要承担者的双重角色,这种迁移模式对女性的劳动供给行为会造成重大的影响。利用浙江省农民工的调查数据,试图考察家庭式迁移女性农民工劳动供给的影响因素。分析结果表明:工作经验、培训经历、本地生活时间、工资对女性农民工的劳动供给具有显著影响;家庭结构的影响不显著,但子女或老人随迁会显著降低女性的劳动参与率和工作时间;分位数回归结果表明,各因素对女性工作时间不同分位数上的影响具有明显变化。     

An alternative to the analysis of covariance for comparing randomized treatments

The problem of comparing mean responses for several treatments applied to a common population is considered. The analysis of co-variance ‘ANCOVA’ is frequently used to take advantage of covariate information in this setting, but in many cases ANCOVA's assumption of parallel regression functions precludes the use of ANCOVA. In this paper, an alternative method is developed which does not make this assumption     

Partitioning with Respect to a Control: Unequal Sample Sizes Case

This article describes a method for partitioning with respect to a control for the situation in which the treatment sample sizes are unequal and also for the situation where the treatment sample sizes are equal except for a few missing values. Calculation of the critical values required for finding confidence limits is discussed and tables are presented for the “almost equal” sample size case. An application of this method to length of stay data for congestive heart failure patients is also provided.     

An asymptotic distribution-free selection procedure for a two-way layout problem

This paper deals with an asymptotic distribution-free subset selection procedure for a two-way layout problem. The treatment effect with the largest unknown value is of interest to us. The block effect is a nuisance parameter in this problem. The proposed procedure is based on the Hodges-Lehmann estimators of location parameters. The asymptotic relative efficiency of the proposed procedure with the normal means procedure is evaluated. It is shown that the proposed procedure has a high efficiency.     

江苏省农村高血压防治知识知晓及治疗依从性分析

目的：分析江苏省农村地区高血压患者防治知识知晓和依从性情况及其影响因素,为探索农村高血压县乡村协作管理策略提供依据。方法：采用率等描述性分析防治知识知晓和治疗依从性,通过χ2检验和Logistic回归等推断性分析影响因素。结果：高血压防治知识知晓率为75.6%（苏南64.8%,苏中74.6%和苏北84.0%）,婚姻状况、文化程度和地区是影响因素;88.2%患者的服药依从性较好（苏南92.9%,苏中92.6%和苏北79.0%）,地区和防治知识知晓情况是影响因素。结论：不同地区需结合自身特点,组建县乡村高血压纵向协作团队,提高患者防治知识知晓和治疗依从性。     

基于按排计费费用核算的城市生活垃圾付费模式研究

当前中国城市生活垃圾收费还是以人为单位进行核算,存在着征费率低、费用被占用、挪用现象严重等问题.为了彻底改变这种状况,必须要借鉴发达国家的城市生活垃圾按排付费模式,从经济刺激视角出发,运用边际成本理论,系统地分析按排计费费用核算中的固定费用和变动费用具体构成.同时,根据管理区域,基础设施状况、人口数量和人均收入的差别,设计出适合中国城市复杂多样性特点的按箱付费模式、按袋付费模式、按量付费模式和混合付费模式四种具体城市生活垃圾按排付费模式,并对这四种具体付费模式的实施维度进行比较分析.
