失去脚后跟:荒诞的生存感

多和田叶子在《失去脚后跟》中以一种奇特的表现方式,抒写了现代人在异域文化冲突中荒诞的生存感受与生存处境,以及人与人之间的扭曲关系。通过对人物心理体验的挖掘和表现手法的分析,以及“失去脚后跟”诸意象隐喻意义的探寻,揭示了现代人的精神困境。     

"信访权"之宪法定位

我国宪法并无信访权的规定,但一般认为,信访制度的宪法依据是宪法第41条,是公民宪法赋予的建议权、申诉权的具体体现。然而从实践和宪法权利理论出发,有必要对信访权加以分解,分为政治性权利和非政治性权利,从代议机构监督和制衡行政权的高度加强信访制度建设,推进我国宪政制度的完善。

Statistics for weighing benefits and harms in a proposed genetic substudy of a randomized cancer prevention trial

Summary.  When evaluating potential interventions for cancer prevention, it is necessary to compare benefits and harms. With new study designs, new statistical approaches may be needed to facilitate this comparison. A case in point arose in a proposed genetic substudy of a randomized trial of tamoxifen versus placebo in asymptomatic women who were at high risk for breast cancer. Although the randomized trial showed that tamoxifen substantially reduced the risk of breast cancer, the harms from tamoxifen were serious and some were life threaten-ing. In hopes of finding a subset of women with inherited risk genes who derive greater bene-fits from tamoxifen, we proposed a nested case–control study to test some trial subjects for various genes and new statistical methods to extrapolate benefits and harms to the general population. An important design question is whether or not the study should target common low penetrance genes. Our calculations show that useful results are only likely with rare high penetrance genes.     

被遮蔽的"文革"叙事--从《玫瑰门》评论小史谈起

<玫瑰门>是铁凝20世纪80年代后期一部以"文革"为背景的重要作品,但从<玫瑰门>的评论小史可以看到,80年代后半期以来,评论界对"文革"主题的忽略与遮蔽是普遍的.其中对抽象人性的偏爱,导致评论界对铁凝等一些小说家揭开"文革"政治对人性阴暗面的催生和放大,与人性固有之丑陋的合谋真相这一努力,大多视而不见.这一情形与80年代中期开始形成的当代文学观密不可分,也与"瞻前"而非"顾后"的社会文化心理有着内在的联系.     

Factor analysis for ranked data with application to a job selection attitude survey

Summary.  Factor analysis is a powerful tool to identify the common characteristics among a set of variables that are measured on a continuous scale. In the context of factor analysis for non-continuous-type data, most applications are restricted to item response data only. We extend the factor model to accommodate ranked data. The Monte Carlo expectation–maximization algorithm is used for parameter estimation at which the E-step is implemented via the Gibbs sampler. An analysis based on both complete and incomplete ranked data (e.g. rank the top q out of k items) is considered. Estimation of the factor scores is also discussed. The method proposed is applied to analyse a set of incomplete ranked data that were obtained from a survey that was carried out in GuangZhou, a major city in mainland China, to investigate the factors affecting people's attitude towards choosing jobs.     

基于移动代理的新型IDS维护更新机制设计

提出了一种基于移动代理的新型分布式入侵检测系统。该系统是针对广域网环境专门设计的,数据的处理通过各节点所设置的代理来进行分布式计算,不仅能实现全网络范围内的入侵检测功能,具有良好的可移植性;而且对网络系统和主机的资源占用较低,减少了出现网络瓶颈的可能。还建立了移动代理的新型分布式入侵检测系统的体系结构和理论分析模型,并讨论了该系统的维护更新机制。     

《历代微型小说选》词语札记

导致古代文学作品译注“望文生训”的原因之一,是在选择与确定词的语义时脱离了交际的语言环境,所以,《列异传》中的“生人气”、“略无”和《列女传》中的“便利”不应是“陌生人的气息”、“略微没有”和“方便”之义,而应该是“活人的气息”、“全无”和“有利可图”之义。     

心灵的失落与追寻——简论汉末男性诗人的女性同构心理

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。     

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.
