个人健康医疗信息和隐私权保护

个人健康医疗信息是个人信息的组成部分,是可以用于识别主体的符号,个人健康医疗信息的控制权为生成者所拥有。个人健康医疗信息的综合性使其价值高于单一的个人信息。个人健康医疗信息控制权丧失后,具有不可回复性。个人健康医疗信息的控制权、管理权、使用权可适当分离。隐私权是一项独立的人格权。为了维护公共利益,个人隐私权应当适度克减;同时,政府具有保护个人健康医疗信息的义务。

构建面向新世纪的消费方式

目前 ,我国居民消费正处在新旧消费方式交替转换时期。在绿色消费、信贷消费、信息消费等新兴消费方式不断涌现 ,给人们生活带来极大便利的同时 ,一些传统、腐朽、落后的消费方式依然在社会上存在 ,并不断蔓延。因此为确保我国经济建设的顺利开展和人民生活水平的稳步提高 ,必须采取切实有效的措施 ,逐步建立与我国社会主义市场经济体制相适应的科学、文明、健康、节约的消费方式。     

论教育信息化背景下教师角色转变

Bayesian model selection for join point regression with application to age-adjusted cancer rates

Summary.  The method of Bayesian model selection for join point regression models is developed. Given a set of K +1 join point models M ₀,  M ₁, …,  M _K with 0, 1, …,  K join points respec-tively, the posterior distributions of the parameters and competing models M _k are computed by Markov chain Monte Carlo simulations. The Bayes information criterion BIC is used to select the model M _k with the smallest value of BIC as the best model. Another approach based on the Bayes factor selects the model M _k with the largest posterior probability as the best model when the prior distribution of M _k is discrete uniform. Both methods are applied to analyse the observed US cancer incidence rates for some selected cancer sites. The graphs of the join point models fitted to the data are produced by using the methods proposed and compared with the method of Kim and co-workers that is based on a series of permutation tests. The analyses show that the Bayes factor is sensitive to the prior specification of the variance σ ², and that the model which is selected by BIC fits the data as well as the model that is selected by the permutation test and has the advantage of producing the posterior distribution for the join points. The Bayesian join point model and model selection method that are presented here will be integrated in the National Cancer Institute's join point software ( http://www.srab.cancer.gov/joinpoint/ ) and will be available to the public.

Empirical likelihood inference for a common mean in the presence of heteroscedasticity

The authors develop empirical likelihood (EL) based methods of inference for a common mean using data from several independent but nonhomogeneous populations. For point estimation, they propose a maximum empirical likelihood (MEL) estimator and show that it is n‐consistent and asymptotically optimal. For confidence intervals, they consider two EL based methods and show that both intervals have approximately correct coverage probabilities under large samples. Finite‐sample performances of the MEL estimator and the EL based confidence intervals are evaluated through a simulation study. The results indicate that overall the MEL estimator and the weighted EL confidence interval are superior alternatives to the existing methods.
