悬垂话题句的线性化研究

根据关系化测试法，悬垂话题句可以分为移位生成和基础生成两大类型。话题移位的激发机制来源于移位成分不可解释的[-Topic]特征；线性化理论决定拼读时复制成分的删除模式。移位生成的话题句中，只有删除除了句首所有的话题复本才是最优的选择；基础生成的话题句在循环线性化的理论下可以直接生成。     

新时期大学生不良行为的成因与矫正

在高等教育大众化时代，大学生的不良行为逐渐增多，影响了他们的健康成长。其不良行为的表现是多方面的，成因也是复杂的，必须从多个角度加以分析。高校应当采取有效对策，妥善解决这些问题，努力提高人才的培养质量。

Conditional moving linear regression: Modeling the recruitment process for ALLHAT

Effective recruitment is a prerequisite for successful execution of a clinical trial. ALLHAT, a large hypertension treatment trial (N = 42,418), provided an opportunity to evaluate adaptive modeling of recruitment processes using conditional moving linear regression. Our statistical modeling of recruitment, comparing Brownian and fractional Brownian motion, indicates that fractional Brownian motion combined with moving linear regression is better than classic Brownian motion in terms of higher conditional probability of achieving a global recruitment goal in 4-week ahead projections. Further research is needed to evaluate how recruitment modeling can assist clinical trialists in planning and executing clinical trials.     

如何追求文学的精神高度——毕淑敏小说创作论

毕淑敏是一个不断开辟新的人生体验和文学描写的有追求的作家。她的创作给文坛带来新的界面，也提出新的命题。这突出体现在四个方面：作家气质：“白衣天使”与“天才病友”的路径选择；面对疾病：隐喻与治疗的相互矛盾；审视心灵：揭示痛苦与展现隐私的暧昧立场；伦理难题：医学一社会学一文学的彼此纠缠。对毕淑敏创作的深度分析，也同时揭示出当代文学如何追求精神高度的困难所在。     

浅析西部民族区域法律文化的培植

当前中国正处在由落后的传统农业社会向先进的现代化工业社会转型的关键时期。改革开放三十年来,我国西部地区经济生活和社会结构发生了巨大的变化,同时,与此相应的法律文化观念也有了一定的提高。但西部地区复杂的民族成分,多样的宗教信仰,保守落后的传统文化等客观或主观方面的不足之处也成为制约区域法律文化成长的障碍。本文针对西部区域民族法律文化的现状、特点,分析其中培植现代法律文化存在的不利因素,并试图找到在西部地区培植区域法律文化的合适路径。     

老年药品广告、消费市场与有限效果

随着我国社会老龄化进程的加速，老年人健康问题日益受到关注。老年群体的庞大基数、高发病率带来的药品市场的巨大需求刺激了老年常用药品广告的迅速繁荣。老年人作为消费主体的特殊性及药品作为消费品的特殊性，使老年常用药品广告具有独特的研究价值。以南京市有交流能力的老年人为样本总体，采用问卷为主、访谈为辅的研究方式进行实证性抽样调查。研究发现，老年常用药品广告承受着老年群体特质所导致的权威崇拜与经验强势的双重阻力，在其有限效果的背后，蕴含源自老年受众群体特质的深层原因。     

Species richness,phylogenetic and functional structure of bird communities in Chinese university campuses are associated with divergent variables

University campus is an important component of urban landscapes for biodiversity conservation. However, to our knowledge no study has quantitatively assessed the diversity and structure of bird communities in Chinese university campuses, especially from phylogenetic and functional perspectives. Here, for the first time we linked species richness, phylogenetic structure and body mass structure of campus bird communities with contemporary climate, glacial-interglacial climate change, altitudinal range, population density around campus, area and age of campus to test their associations. We found 393 bird species in 38 university campuses (29% of all Chinese bird species, two species are endangered, four species are vulnerable, and 33 species are near threatened). The variables significantly correlated with campus bird species richness, phylogenetic structure and body mass structure were altitudinal range and mean annual precipitation, glacial-interglacial anomaly in temperature, and altitudinal range, respectively. In particular, there were more species in steeper and wetter campuses, more young species clustered in campuses with stable glacial-interglacial climate, and more species with smaller body size in steeper campuses. Our study highlights the importance of considering both phylogenetic and functional information for biodiversity conservation in urban ecosystems.     

关于检验抗病毒药物有效性样本量的比较

文章基于链式二项式模型,运用符号秩和检验法,将检验抗病毒药物的有效性及所需样本容量与Alexander-Govern检验进行了比较研究,并分析了抗病毒药物的不同控制策略对检验抗病毒药物有效性所需样本容量的影响.研究表明,符号秩和检验所需样本量比becker和wang所用的Alexander-Govern检验所需样本量更少,并且采用治疗加预防策略且尽早发放药物可有效减少样本容量.
