Nonparametric regression with cross‐classified responses

In this article, we develop regression models with cross‐classified responses. Conditional independence structures can be explored/exploited through the selective inclusion/exclusion of terms in a certain functional ANOVA decomposition, and the estimation is done nonparametrically via the penalized likelihood method. A cohort of computational and data analytical tools are presented, which include cross‐validation for smoothing parameter selection, Kullback–Leibler projection for model selection, and Bayesian confidence intervals for odds ratios. Random effects are introduced to model possible correlations such as those found in longitudinal and clustered data. Empirical performances of the methods are explored in simulation studies of limited scales, and a real data example is presented using some eyetracking data from linguistic studies. The techniques are implemented in a suite of R functions, whose usage is briefly described in the appendix.

Dependence Estimation Over a Finite Bivariate Failure Time Region

This articleconcerns nonparametric estimation of association between bivariatefailure times. In the presence of independent right censoring,the support for failure time variates may be restricted and measuresof dependence over a finite failure time region may be of particularinterest. To this end, the reciprocal cross ratio function, weightedby the bivariate failure time density, is proposed as a summarymeasure of dependence over a failure time region. This `relativerisk' estimator is shown to be consistent and asymptoticallynormally distributed, with consistent bootstrap variance estimator.A finite-region version of Kendall's tau, which is suitable forcensored failure time data, is also proposed, and correspondingasymptotic distribution theory is noted. The accuracy of theseasymptotic approximations is studied in simulations and an illustrationis provided.     

Using Epidemiological Studies to Check the Consistency of the Cancer Risks Predicted by High-Dose Animal Experiments: A Methodological Review

Epidemiological studies have been cited in the literature as evidence both for and against the human cancer risks predicted by high-exposure rodent studies. However, there has been little overall consistency in the ways that these animal-to-human comparisons have been made. This review examines some examples of these types of comparisons and describes the methods and techniques used by different investigators. Eleven "key decision areas" that need to be addressed are identified and recommendations for consistent, logical, and statistically appropriate approaches that might be taken to standardize the process are provided. In general, it is suggested that investigators provide the most useful information when they use logical, transparent, and statistically valid comparisons to pursue limited and focused objectives, such as directly testing the validity of an existing regulatory guidance value. Other recommendations include selecting biologically plausible extrapolative models that fit the data and drawing conclusions that are consistent with the study results and objectives.

跨文化交际视阈下的旅游宣传资料英译研究

旅游宣传资料的英译是译者、作者和国外游客之间的一种跨时空、跨文化交际活动.旅游宣传资料的翻译者必须增强自身的跨文化敏感性,既精通两种语言又熟谙两种文化,最大限度地兼容交际双方的语言习惯、文化心理、交际规约和价值标准差异.本文试以比较中英旅游宣传资料在遣字用词、句式结构、谋篇布局、文本内容等方面的差异为路径,揭示中英两种语言体系所承载的语言习惯、价值观念、思维模式、民族心理、审美情趣等跨文化交际要素的差异,并提出跨文化交际视阈下的旅游宣传资料英译的原则和方法.     

Widowhood and Well‐being in Europe: The Role of National and Regional Context

Researchers have documented that widows have lower levels of subjective well‐being than married individuals, but we still know little about how the regional and national contexts affect the impact of widowhood on well‐being. Building on social capital theory and using data from 5 rounds of the European Social Survey (N= 119,292 people, 206 regions, 23 countries), the authors tested how marital status composition at the national and regional levels affects the well‐being of widows. Widows fare worse in countries with high proportions of married people and in regions and countries with high proportions of widowed persons. The proportion of married individuals at the regional level does not affect their well‐being. These results are in line with the greedy marriage hypothesis, but varying effects at regional and national levels suggest that the standard explanation for this phenomenon, lack of individual social support, is not valid. This study demonstrates the importance of multiple contextual embeddedness.     

论史学方法体系的重建

中西学术思想及其史学观念的新进展 ,为我国史学方法体系的重建提供了理论前提。以罗荣渠的现代化研究、白寿彝总主编的《中国通史》、李学勤等人的“夏商周断代工程”为典型的具体历史研究 ,既为重建史学方法体系奠定了现实基础 ,又启发我们必须把跨学科方法作为史学方法新体系的中心内容。在跨学科方法中 ,除了自然科学和社会科学方法之外 ,还应对人文学科的方法给予特别的重视。     

Investigating Differences in How the News Media Views Homosexuality Across Nations: An Analysis of the United States,South Africa,and Uganda

While there is a wealth of information about the extent to which people across the world disapprove of homosexuality, we know a lot less about the lenses through which they view same‐sex relations. The aim of this study is to understand better how homosexuality is framed in the public press, and how religion and economic development may combine to shape this discourse. Through an analysis of almost 400 newspaper articles, this study compares how homosexuality is framed in Uganda, South Africa, and the United States. Because these nations have high levels of religious belief, but differ in their level of economic development and democracy, we can assess how these factors interact to shape portrayals. Drawing on work from cultural sociology and the sociology of religion, this study shows that the United States is much more likely than Uganda to frame homosexuality as a civil rights issue and use entertainers as claimsmakers. Conversely, articles from Uganda are more likely than those from the United States or South Africa to frame homosexuality as a religious issue and draw on religious claimsmakers. Likewise, Uganda is much more likely than South Africa to discuss homosexuality in the context of Western influences.

Estimation in an empirical bayes model for longitudinal and cross‐sectionally clustered binary data

Some studies generate data that can be grouped into clusters in more than one way. Consider for instance a smoking prevention study in which responses on smoking status are collected over several years in a cohort of students from a number of different schools. This yields longitudinal data, also cross‐sectionaliy clustered in schools. The authors present a model for analyzing binary data of this type, combining generalized estimating equations and estimation of random effects to address the longitudinal and cross‐sectional dependence, respectively. The estimation procedure for this model is discussed, as are the results of a simulation study used to investigate the properties of its estimates. An illustration using data from a smoking prevention trial is given.
