从"唐人选唐诗"看王昌龄在唐代诗坛地位的变迁

“唐人选唐诗”录王昌龄诗歌作品的情况反映出唐代不同时期人们对王昌龄诗歌接受态度及其在唐代诗坛地位的升降变迁。总体而言 ,昌龄因其五言古诗对盛唐诗风的开拓之功而受到当时选家普遍重视 ,有“诗家夫子”之称 ,中唐以后选家则独重昌龄七言绝句 ,虽以“七绝圣手”誉之 ,但其诗歌地位已非显著。文章同时指出 ,作为古代诗歌批评的一种特殊形态 ,唐诗选本所蕴含的诗学价值应受到重视 ,成为唐诗学研究的一个方向

Methods to assess measurement error in questionnaires of sedentary behavior

Sedentary behavior has already been associated with mortality, cardiovascular disease, and cancer. Questionnaires are an affordable tool for measuring sedentary behavior in large epidemiological studies. Here, we introduce and evaluate two statistical methods for quantifying measurement error in questionnaires. Accurate estimates are needed for assessing questionnaire quality. The two methods would be applied to validation studies that measure a sedentary behavior by both questionnaire and accelerometer on multiple days. The first method fits a reduced model by assuming the accelerometer is without error, while the second method fits a more complete model that allows both measures to have error. Because accelerometers tend to be highly accurate, we show that ignoring the accelerometer's measurement error, can result in more accurate estimates of measurement error in some scenarios. In this article, we derive asymptotic approximations for the mean-squared error of the estimated parameters from both methods, evaluate their dependence on study design and behavior characteristics, and offer an R package so investigators can make an informed choice between the two methods. We demonstrate the difference between the two methods in a recent validation study comparing previous day recalls to an accelerometer-based ActivPal.

Pollution disclosures,pollution performance and economic performance

This study examines the association between pollution disclosures and pollution performance and between pollution disclosures and economic performance for firms in highly polluting industries. An index of pollution disclosures is developed and correlated with indices of pollution performance and economic performance. The results confirm earlier findings that there is no association between pollution disclosures and pollution performance. As far as the association between economic performance and pollution disclosures is concerned, the results show that the subgroup of large firms with poor economic performance provides the most detailed pollution information. For smaller firms there is no association between economic performance and pollution disclosures.     

Correlation bias in U.S. census adjustment

One form of error that can affect census adjustments is correlation bias, reflecting people who are doubly missing--from the census and from the adjusted counts as well. This article presents a method for estimating the total national number of doubly-missing people and their distribution by race and sex. Application to the 1990 U.S. census adjustment leads to an estimate of 3 million doubly-missing people. Correlation bias is likely to be a serious problem for census adjustment in 2000. The methods of this article are well suited for measuring its magnitude.     

中国的东北和日本的东北——对中日构筑“大东北经济圈”的思考与建议

2006年10月安倍首相上任伊始，便决定访问中国，展开了“破冰之旅”，结束了中日之间自2001年小泉上台由于参拜靖国神社引发的对立和矛盾，此后“融冰之旅”、“迎春之旅”使中日战略互惠关系不断向前推进。胡锦涛总书记的“暖春之旅”使两国战略互惠关系进入全面升级阶段。在上述氛围推动下，两国的经贸也不断取得突破，中日贸易超过美日贸易，中国成为日本第一大贸易伙伴。随着两国在各个领域的相互依赖不断加深，以区域合作为纽带、以友好城市发展为拉动，两国的地方交流也出现蓬勃发展势头。尤其是我们的东北振兴战略持续深化，使两国在东北地区的各种合作不断增加，学术、经济和企业界甚至发出了打造“中日大东北经济圈”的热切呼声。从中日经贸互动和地方国际合作背景来看，随着两国在东北地区合作的不断深入，中日构筑“东北经济圈”不但具有可能性而且时机日渐成熟。     

A new class of measurement-error models,with applications to dietary data

Measurement-error modelling occurs when one cannot observe a covariate, but instead has possibly replicated surrogate versions of this covariate measured with error. The vast majority of the literature in measurement-error modelling assumes (typically with good reason) that given the value of the true but unobserved (latent) covariate, the replicated surrogates are unbiased for latent covariate and conditionally independent. In the area of nutritional epidemiology, there is some evidence from biomarker studies that this simple conditional independence model may break down due to two causes: (a) systematic biases depending on a person's body mass index, and (b) an additional random component of bias, so that the error structure is the same as a one-way random-effects model. We investigate this problem in the context of (1) estimating distribution of usual nutrient intake, (2) estimating the correlation between a nutrient instrument and usual nutrient intake, and (3) estimating the true relative risk from an estimated relative risk using the error-prone covariate. While systematic bias due to body mass index appears to have little effect, the additional random effect in the variance structure is shown to have a potentially important effect on overall results, both on corrections for relative risk estimates and in estimating the distribution of usual nutrient intake. However, the effect of dietary measurement error on both factors is shown via examples to depend strongly on the data set being used. Indeed, one of our data sets suggests that dietary measurement error may be masking a strong risk of fat on breast cancer, while for a second data set this masking is not so clear. Until further understanding of dietary measurement is available, measurement-error corrections must be done on a study-specific basis, sensitivity analyses should be conducted, and even then results of nutritional epidemiology studies relating diet to disease risk should be interpreted cautiously.
