英语引申意境的探析

英语中的引申是一种普遍现象。英译汉时不仅有时词义要引申。词组、分句或句子的含义有时也要引申,英语引申的意境,可以从褒与贬、抽象与具体、词义搭配、概念大小、逻辑修辞、引申层次和引申范围七个不同方面来探析。     

Parent‐Adolescent Communication About Sex: Retrospective Reports by Latino College Students

Latina female (n= 97) and Latino male (n= 69) college students (M age = 21.4 years) completed self‐report surveys regarding family of origin experiences, including sexual communication with parents while growing up. Latino parents of this comparatively highly educated sample tended to use direct rather than indirect strategies for communicating about sexuality with their children. Young women reported higher levels of sexual communication with mothers while growing up than did young men, and respondents reported less communication with fathers than mothers. Among young women, sexual communication with mother was positively associated with non‐Mexican origin and negatively associated with having older brothers living at home. In contrast, maternal education was positively associated with mother‐son communication about sex. Paternal education and the absence of older brothers positively predicted communication with both sons and daughters. The analyses provide novel information regarding sexual communication in Latino families and suggest directions for future research.     

Choice of the primary analysis in longitudinal clinical trials

Missing data, and the bias they can cause, are an almost ever‐present concern in clinical trials. The last observation carried forward (LOCF) approach has been frequently utilized to handle missing data in clinical trials, and is often specified in conjunction with analysis of variance (LOCF ANOVA) for the primary analysis. Considerable advances in statistical methodology, and in our ability to implement these methods, have been made in recent years. Likelihood‐based, mixed‐effects model approaches implemented under the missing at random (MAR) framework are now easy to implement, and are commonly used to analyse clinical trial data. Furthermore, such approaches are more robust to the biases from missing data, and provide better control of Type I and Type II errors than LOCF ANOVA. Empirical research and analytic proof have demonstrated that the behaviour of LOCF is uncertain, and in many situations it has not been conservative. Using LOCF as a composite measure of safety, tolerability and efficacy can lead to erroneous conclusions regarding the effectiveness of a drug. This approach also violates the fundamental basis of statistics as it involves testing an outcome that is not a physical parameter of the population, but rather a quantity that can be influenced by investigator behaviour, trial design, etc. Practice should shift away from using LOCF ANOVA as the primary analysis and focus on likelihood‐based, mixed‐effects model approaches developed under the MAR framework, with missing not at random methods used to assess robustness of the primary analysis.

统筹城乡发展与完善农村土地流转制度的思考

针对中国农村土地流转不畅阻碍统筹城乡发展的现状,政府应从城乡两个方面完善土地流转制度,即建立与土地流转制度相关的制度体系,包括土地使用权市场、培育土地流转中介组织、集中使用农业补贴和以土地换保险等制度。为确保土地流转促进统筹城乡发展,实现城镇政府和进城务工农民的双赢,政府应对自身行为加以规范。     

草原牧区生态移民及其对策

随着我国草原的日益退化，牧民的生存和发展形势严峻，牧区的生态移民问题已经提到议事日程，并在我国许多牧区开始实践。该文对牧区生态移民的成因和途径做了初步的探索。我国牧区人口已超出了生态环境的承受力，许多牧民已经丧失了基本生产生活资料——草原。草原封育需要牧区进行生态移民，要用科学的发展观指导牧区生态移民；政府要用宏观、开放的视野指导牧区生态移民，不能局限在一时一地解决这一问题；向牧区未利用草原移民；改革牧区的第一产业，发展牧区的第二、三产业，为牧民创造更多的就业岗位以减轻向系统外移民的压力；向农村和城镇转移，实现从草原生态经济系统向系统外移民。     

Marginal and association regression models for longitudinal binary data with drop‐outs: A likelihood‐based approach

Longitudinal data often contain missing observations, and it is in general difficult to justify particular missing data mechanisms, whether random or not, that may be hard to distinguish. The authors describe a likelihood‐based approach to estimating both the mean response and association parameters for longitudinal binary data with drop‐outs. They specify marginal and dependence structures as regression models which link the responses to the covariates. They illustrate their approach using a data set from the Waterloo Smoking Prevention Project They also report the results of simulation studies carried out to assess the performance of their technique under various circumstances.
