论实践对质的确定

实践确定质的依据是:第一、事物作为客体是主体实践活动的对象;第二、事物及其质都是主客体相互作用的结果。质兼有主观性和客观性,体现着主客观的统一。质由实践确定,其机理是:第一,事物的存在状态同人的实践需要相契合,事物的某些潜在功能和属性显化出来,被主体确定为该事物的质;第二,在实践中人通过思维把某一时间内事物的相对稳定状态确定为系统质的某个方面;第三,事物被实践改造或重塑而形成新的系统质。

Regularization through variable selection and conditional MLE with application to classification in high dimensions

It is often the case that high-dimensional data consist of only a few informative components. Standard statistical modeling and estimation in such a situation is prone to inaccuracies due to overfitting, unless regularization methods are practiced. In the context of classification, we propose a class of regularization methods through shrinkage estimators. The shrinkage is based on variable selection coupled with conditional maximum likelihood. Using Stein's unbiased estimator of the risk, we derive an estimator for the optimal shrinkage method within a certain class. A comparison of the optimal shrinkage methods in a classification context, with the optimal shrinkage method when estimating a mean vector under a squared loss, is given. The latter problem is extensively studied, but it seems that the results of those studies are not completely relevant for classification. We demonstrate and examine our method on simulated data and compare it to feature annealed independence rule and Fisher's rule.

从释义到推论——余英时《朱熹的历史世界》史料解读献疑

余英时先生《朱熹的历史世界》一书重构两宋（尤其是南宋）政坛面貌,旁征博引,新见迭出,深得学界好评。然而通读全书,作者对若干史料的运用,似不无令人生疑之处。书中史料处理的疑点。主要可分为：字词含义、语段脉络、史料性质、推论程序四类。     

工业结构转型与工业增长质量——以中国浙江省为例

文章基于工业结构演进的一般理论和结构转型分析模型,实证分析了浙江省11区域的工业行业特化度、结构转型方向和工业增长质量的差异情况。分析结果表明:属于特化-普化增长型的杭州、嘉兴等区域的工业比较劳动生产率呈不断上升趋势,而这些区域的工业发展主要是由技术水平高或生产效率高的行业带动的,正是这些行业的增长推动了工业结构优化或升级,从而提高了工业发展层次;而属于特化增长型的宁波、温州等区域的工业比较劳动生产率却呈下降趋势,其原因在于这些区域的工业增长主要是由技术水平低或生产效率较低行业实现的,这些低技术低效率行业的增长导致其工业结构劣化,影响了这些区域的工业发展层次和工业增长质量。     

Long and happy living: Trends and patterns of happy life expectancy in the U.S., 1970–2000

This study assesses the trends and differentials in length of quality life in the U.S. population as measured by happy life expectancy in 1970, 1980, 1990, and 2000. The analysis combines age-specific prevalence rates of subjective well-being from a large nationally representative survey and life table estimates of mortality in decennial Census years. Employing the period prevalence-rate life table method—Sullivan method, the analysis finds evidence for improvement in quality of life in the U.S. Happy life expectancy largely increased in both absolute terms (number of years) and relative terms (proportion of life) over time at all adult ages examined. And increases in total life expectancy were mainly contributed by increases in expectancy in happy years rather than unhappy years. Happy life expectancy is longer than active life expectancy. And there has been greater compression of unhappiness than compression of morbidity. There are substantial differentials in happy life expectancy by sex and race because of differential prevalence rates of happiness. Women and whites had longer years of total and happy life expectancies at most ages and dates, while men and blacks had greater proportions of happy life expectancies across the three decades. Although race differentials generally decreased at older ages and with time, relative disadvantages of blacks persisted.     

Education,Happiness and Wellbeing

Answers to the questions ‘Does education influence happiness and if so, how and how much?’ depend on how one defines and operationalizes ‘education’, ‘influences’ and ‘happiness’. A great variety of research scenarios may be constructed from our three essential variables. What public policies one ought to adopt and implement regarding the influence of education on happiness depends minimally on which of the great variety of research scenarios one adopts and maximally on lots of other things as well. My personal preference is for a robust definition of the three terms. Because human beings are complex organisms, an adequate construction of the idea of human wellbeing must also be complex. Therefore, any discipline-driven, reductionist definition that pyschologizes, medicalizes, economizes, geneticizes, socializes or politicizes the idea should be avoided.     

The Relative Importance of Health

This article seeks to extend Michalos’ [Social indicators research and health-related quality of life (QoL) research. Social Indicators Research, 65, 27–72, 2004] discussion on bridging social indicators research and health-related QoL (HRQoL) research through an examination of (1) the relative importance of satisfaction with one’s own health to another common measure of QoL—Life satisfaction, and (2) the relative importance of health in relation to other major life domains. Using data from two surveys, this article found that individuals may perceive health as most important in relation to other major life domains but satisfaction with one’s own health may not necessarily be the most important determining factor (in relation to satisfaction with other major life domains) of QoL as measured by life satisfaction. These findings support Michalos’ (Social indicators research and HRQoL research. Social Indicators Research, 65, 27–72, 2004) call for caution regarding the interpretation of research results on HRQoL since many HRQoL measures are measures of satisfaction with one’s own health and should not be considered as measures of QoL.
