Optimal Prediction in Stochastic Regression Models with Application to the Analysis of Repeated Surveys

Several results relating to the optimal prediction of regression coefficients and random variables under a general linear model with stochastic coefficients are presented. These results are then applied to the analysis of repeated sample surveys over time. In particular, if the finite population can be modelled by a superpopulation model, a fully efficient method for the analysis of repeated surveys is proposed.

从关联翻译理论看儿童文学的翻译——《夏洛的网》汉译本个案研究

运用关联翻译理论,比较了儿童文学作品《夏洛的网》的两个汉译本,探索了翻译理论对儿童文学翻译的指导作用。关联翻译理论带给儿童文学翻译很多启示。首先,译者需要寻求最佳关联性,生成符合译语规范的、通顺的译文;其次,要考虑译语读者与原语读者认知环境不同,进行创造性叛逆;最后,译者需要忠实传递作者的意图,使译文读者获得与原文读者一样多的语境效果。     

Combining information from multiple surveys for assessing health disparities

Despite advances in public health practice and medical technology, the disparities in health among the various racial/ethnic and socioeconomic groups remain a concern which has prompted the Department of Human and Health Services to designate the elimination of disparities in health as an overarching goal of Healthy People 2010. To assess the progress towards this goal, suitable measures are needed at the population level that can be tracked over time; Statistical inferential procedures have to be developed for these population level measures; and the data sources have to be identified to allow for such inferences to be conducted. Popular data sources for health disparities research are large surveys such the National Health and Interview Survey (NHIS) or the Behavior Risk Factor Surveillance System (BRFSS). The self-report disease status collected in these surveys may be inaccurate and the errors may be correlated with variables used in defining the groups. This article uses the National Health and Nutritional Examination Survey (NHANES) 99-00 to assess the extent of error in the self-report disease status; uses a Bayesian framework develop corrections for the self-report disease status in the National Health Interview Survey (NHIS) 99-00; and compares inferences about various measures of health disparities, with and without correcting for measurement error. The methodology is illustrated using the disease outcome hypertension, a common risk factor for cardiovascular disease. JEL classification C1 (C11, C13, C15), C4 (C42) and I3 (I31, I38)     

E.B.怀特《夏洛的网》中的生态幻想世界

美国作家E.B.怀特在小说《夏洛的网》中以生动幽默的笔触构筑了人类世界与自然世界。在两者的双峰对峙中,怀特呈现了人类世界的人类中心主义、对自然的破坏以及自然世界的清新美好、动物的友爱互助,从而表达了对人与自然的关系、爱、友谊等问题的思考,传达了深刻的思想内涵。在《夏洛的网》所呈现的幻想世界中,夏洛、坦普尔顿等动物有深刻的寓意,并形成对比映衬关系。     

碎片·场景·沉浸——由互联网+短视频看未来电影制作的发展趋势

互联网2.0时代的媒介特性要求传播内容应具有碎片化、场景式与沉浸式的特点。短视频又短又快的传播形式,恰是互联网对传播内容碎片化要求的体现;以趣缘聚类组织的垂直内容,暗合场景式传播的要求;视频制作技术的进步,成为沉浸式的视听体验的技术支持。由此可以窥见未来电影的发展图景,即更短的电影时长和镜头长度、依大数据算法决策的电影制作以及仿真的沉浸式的视听体验。     

Some Results on Modeling Biological Sequences and Web Navigation with a Semi Markov Chain

In the article, the entrance probabilities and the probability distribution of the number of transitions to a state are studied to provide some answers to questions related to state occupancies for the semi Markov model. Biological sequences and Web navigation are two cases that initially seem to be different but to a certain extent they do have similarities. Two main aspects of word occurrences in biological sequences are: (a) where do they occur and (b) how many times do they occur. In Web navigation the similar questions are (a) when a node is visited and (b) how many times a node is visited. So, the theoretical results of this study are applied to model these two cases and derive distributions of word location or node occurrence and frequency of occurrences. Rewards/costs are included in the Web navigation model and analytic forms for the means, variances, and moments of total interval rewards/costs are provided.
