萧红与20世纪中国女性文学   总被引:1,自引:0,他引:1  
萧红是20世纪中国女性文学最杰出的代表性作家之一,与冰心、丁玲、张爱玲等作家相比,其独特性和不可替代性主要表现为三点第一,没有局限于知识女性的狭窄视野,避免陷入女性文学的精英主义误区,自觉为中国最广大下层女性代言,执著关注中国下层妇女的生存状态和人生悲剧;第二,始终如一地坚持以女性视角和女性生命体验来描绘普通女性生存真相并对她们寄寓着深切悲悯,体现出独立、清醒、深刻的现代女性意识;第三,拓展、丰富、深化了20世纪中国女性文学的表现内涵,提高了其审美品格.  相似文献

李清照的词作 ,无论是就其思想还是就其内容而言 ,都处于当时的主流文学之内 ,为时代所限 ,她本人也不具备当代女性那样强烈的自我意识。但在男性作者占绝大多数的宋代词坛上 ,李清照的女性身份及其词作的女性视角和话语 ,使她的作品具有了独特的历史价值 ,在真实地展现女性生命体验这一点上 ,又具有了不可替代的作用和另一境界。  相似文献

当下,中国的女性主义发展到了一定的阶段,在很多方面消解男权,甚至有超过男性的趋势。在文学上,女性主义文本很多,作家的女性主义意识也十分明显。在这样的情况下,我们通过几个文本并借鉴原型批评和女性主义批评的方法来研究中国女性反叛的发展脉络。  相似文献

The last observation carried forward (LOCF) approach is commonly utilized to handle missing values in the primary analysis of clinical trials. However, recent evidence suggests that likelihood‐based analyses developed under the missing at random (MAR) framework are sensible alternatives. The objective of this study was to assess the Type I error rates from a likelihood‐based MAR approach – mixed‐model repeated measures (MMRM) – compared with LOCF when estimating treatment contrasts for mean change from baseline to endpoint (Δ). Data emulating neuropsychiatric clinical trials were simulated in a 4 × 4 factorial arrangement of scenarios, using four patterns of mean changes over time and four strategies for deleting data to generate subject dropout via an MAR mechanism. In data with no dropout, estimates of Δ and SEΔ from MMRM and LOCF were identical. In data with dropout, the Type I error rates (averaged across all scenarios) for MMRM and LOCF were 5.49% and 16.76%, respectively. In 11 of the 16 scenarios, the Type I error rate from MMRM was at least 1.00% closer to the expected rate of 5.00% than the corresponding rate from LOCF. In no scenario did LOCF yield a Type I error rate that was at least 1.00% closer to the expected rate than the corresponding rate from MMRM. The average estimate of SEΔ from MMRM was greater in data with dropout than in complete data, whereas the average estimate of SEΔ from LOCF was smaller in data with dropout than in complete data, suggesting that standard errors from MMRM better reflected the uncertainty in the data. The results from this investigation support those from previous studies, which found that MMRM provided reasonable control of Type I error even in the presence of MNAR missingness. No universally best approach to analysis of longitudinal data exists. However, likelihood‐based MAR approaches have been shown to perform well in a variety of situations and are a sensible alternative to the LOCF approach. MNAR methods can be used within a sensitivity analysis framework to test the potential presence and impact of MNAR data, thereby assessing robustness of results from an MAR method.

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing  相似文献

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.  相似文献

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.

汉末男性诗人以女性为情感载体来抒写自我生命痛苦的写作用意,应与他们的处境和心态密切相关。在混乱的政局中经历了期盼、失望、绝望的心路历程之后,他们的心态发生了很大变化,具有与女性心理同构的新特点。这恰恰彰显了汉末男性诗人摆脱心灵困境时的自我突围意识。  相似文献
