荞麦中苯丙氨酸解氨酶活力与黄酮含量的关系

荞麦幼苗及幼苗不同器官中黄酮含量随着苯丙氨酸解氨酶（PAL）活力变化而变化。X射线处理可增强荞麦幼苗中苯丙烷类代谢途径,致使黄酮含量提高。由此推测,苯丙氨酸解氨酶活力与黄酮类次生物质的形成具有密切关系。

Bayesian adjustment for unidirectional misclassification in ordinal covariates

In this paper, we study the identification of Bayesian regression models, when an ordinal covariate is subject to unidirectional misclassification. Xia and Gustafson [Bayesian regression models adjusting for unidirectional covariate misclassification. Can J Stat. 2016;44(2):198–218] obtained model identifiability for non-binary regression models, when there is a binary covariate subject to unidirectional misclassification. In the current paper, we establish the moment identifiability of regression models for misclassified ordinal covariates with more than two categories, based on forms of observable moments. Computational studies are conducted that confirm the theoretical results. We apply the method to two datasets, one from the Medical Expenditure Panel Survey (MEPS), and the other from Translational Research Investigating Underlying Disparities in Acute Myocardial infarction Patients Health Status (TRIUMPH).     

在粤印度人状况初探

在粤印度人( 主要是生活在珠三角的印度人) 和整个在华的印度人一样,是一个非常独特的群体。他们以自己特有的方式生活、工作、学习或拓展自己的生意,一直保持着自己独特的生活方式和行为方式,坚持自己的文化特点,在各方面都显示出自己鲜明的特征。印度人在华的商业成功或在中国获得的机会吸引了更多的印度人来到中国。在华印度人,尤其是在粤印度人的人数将会不断增长,中、印通婚的人数也会不断地增加。这对中、印两国关系的方方面面均会产生重大的影响。     

唐国史中的史实遮蔽与形象建构——以玄宗先天二年政变书写为中心

先天二年政变是玄宗最终掌握最高权力的惊险一跃,而这一事件牵涉到玄宗与睿宗父子间激烈的权力争夺,因此唐代史官在国史中对这一事件进行了全面的讳饰。然而以张说所作的郭元振《行状》为切入点,结合相关文献记载,则可展示玄宗与睿宗及太平公主在政变之前激烈的政治较量、七月三日政变当天的整个过程,同时揭示政变后玄宗通过削弱政变功臣郭元振的权柄、最终掌握所有权力的真相。对于这场政变全方位的探索,显示唐代国史的书写通过遮蔽政治事件的关键性细节、重塑参与其中的政治人物,从而使史书记载最终符合其"政治正确"的逻辑。     

Diffusion Indexes With Sparse Loadings

The use of large-dimensional factor models in forecasting has received much attention in the literature with the consensus being that improvements on forecasts can be achieved when comparing with standard models. However, recent contributions in the literature have demonstrated that care needs to be taken when choosing which variables to include in the model. A number of different approaches to determining these variables have been put forward. These are, however, often based on ad hoc procedures or abandon the underlying theoretical factor model. In this article, we will take a different approach to the problem by using the least absolute shrinkage and selection operator (LASSO) as a variable selection method to choose between the possible variables and thus obtain sparse loadings from which factors or diffusion indexes can be formed. This allows us to build a more parsimonious factor model that is better suited for forecasting compared to the traditional principal components (PC) approach. We provide an asymptotic analysis of the estimator and illustrate its merits empirically in a forecasting experiment based on U.S. macroeconomic data. Overall we find that compared to PC we obtain improvements in forecasting accuracy and thus find it to be an important alternative to PC. Supplementary materials for this article are available online.
