2005年农民增收面临的困难

20 0 4年 ,各级党委和政府认真贯彻落实“一号文件”精神 ,极大地调动起了农民农业生产积极性 ,加上市场粮价回升、农业生产气候条件适宜等多方面有利因素 ,农民增收呈现近年来少有的好形势。据统计 ,全年农民人均纯收入 2 936元 ,增加 314元 ,实际增长 6 8% ,是 1997年以来收入增加最多和增长最快的一年。但是 ,制约农民增收的深层次矛盾还没有得到有效化解 ,2 0 0 5年实现农民收入较快增长的任务还很艰巨。　　一、2 0 0 4年农民增收的特点(一 )农业收入创历史新高农业收入在农民收入中具有举足轻重的地位 ,是农民收入的最大来源。近年来…     

创新办学模式 激活办学潜力——关于福建省侨兴轻工学校教育改革的探索和实践

中职教育,由于受计划经济体制的制约和传统教育思想的束缚,长期以来,存在着重书本知识轻实践技能的弊端,是一种以教师为中心的典型模式。我校围绕“以服务为宗旨,以就业为导向,面向市场和社会办学”的指导思想,顺应形势的发展进行了积极的探索和实践,加快了中职教育教学的改革步伐,促进了学校发展。     

文化生产力的崛起与发展

马克思提出的文化生产力概念包含着正确把握现代社会智能生产力的指导性原则。文化生产力的提出, 使文化知识从非独立因素变为独立因素,由潜在生产力变为现实生产力。文化生产力的高度发展对现代文明的影响是全方位的,将对旧有的生产生活方式、思维方式、价值观念、教育模式和经营管理及领导决策产生重大影响,从而改变财富的分配方式。改革开放以来,我国文化生产力有了突破性发展,但在总体水平上同发达国家的差距很大。应当强化全民的“文化生产力”意识,建立起国家的技术创新体系和知识创新体系,加大对教育和科技的投入。

Bayesian analysis of a marked point process: Application in seismic hazard assessment

Point processes are the stochastic models most suitable for describing physical phenomena that appear at irregularly spaced times, such as the earthquakes. These processes are uniquely characterized by their conditional intensity, that is, by the probability that an event will occur in the infinitesimal interval (t, t+Δt), given the history of the process up tot. The seismic phenomenon displays different behaviours on different time and size scales; in particular, the occurrence of destructive shocks over some centuries in a seismogenic region may be explained by the elastic rebound theory. This theory has inspired the so-called stress release models: their conditional intensity translates the idea that an earthquake produces a sudden decrease in the amount of strain accumulated gradually over time along a fault, and the subsequent event occurs when the stress exceeds the strength of the medium. This study has a double objective: the formulation of these models in the Bayesian framework, and the assignment to each event of a mark, that is its magnitude, modelled through a distribution that depends at timet on the stress level accumulated up to that instant. The resulting parameter space is constrained and dependent on the data, complicating Bayesian computation and analysis. We have resorted to Monte Carlo methods to solve these problems.     

健美操锻炼对高校女生体型的影响

通过对180名健美操选项课的女生进行为期一学年的健美操训练,探索健美操对高校女生体形和姿态的影响.实验前测验显示:多数学生的三围比例不合理,胸围、臀围较小,腹部脂肪堆积较多.通过健美操锻炼可使皮下脂肪的含量减少,去脂体重占的比例增大,三围更接近标准,肢体的柔韧性得到增强.说明健美操锻炼能够有效塑造女性的身材,使女性显得健美,更具有女性的魅力.     

Population constraints on pooled surveys in demographic hazard modeling

In non-experimental research, data on the same population process may be collected simultaneously by more than one instrument. For example, in the present application, two sample surveys and a population birth registration system all collect observations on first births by age and year, while the two surveys additionally collect information on women’s education. To make maximum use of the three data sources, the survey data are pooled and the population data introduced as constraints in a logistic regression equation. Reductions in standard errors about the age and birth-cohort parameters of the regression equation in the order of three-quarters are obtained by introducing the population data as constraints. A halving of the standard errors about the education parameters is achieved by pooling observations from the larger survey dataset with those from the smaller survey. The percentage reduction in the standard errors through imposing population constraints is independent of the total survey sample size.
