论文学     

杨矗 《山西大学师范学院学报》2011,(4):1-10

文学是个非常古老的精神活动、精神形式,但人们对它既熟悉又陌生,熟知却未必真知。加上西方20世纪80年代发生了文学的＂文化转向＂后,文学的疆界变得无限开阔,而其自身的界定也面临空前的危机。因此,对＂文学是什么＂的回答就成了一个迫切的学术问题。而此前的＂形象论＂、＂表现论＂和＂审美意识形态论＂文学观都存在着严重不足,故而需要另辟蹊径,再进行新的界定。新的结论是：从其本源上看,文学是一种高级的魅态文化形式;从其历史面貌上看,文学是个历史性的家族,表现为文学观、特征论、形式定位、流派形态,同时还呈现为杂化和纯化的周期性变奏;从本质的抽象定义看,文学则是象征性的语言艺术,它不以科学和实用为目的,而以想象性超越和诗性的解放为旨归。中国当代文学的致命危机就是＂象征性＂传统谱系的断裂。  相似文献

现代汉语二合复句中分句语气异类组配的倾向性研究     

万光荣  储泽祥 《暨南大学华文学院学报》2011,(4):64-71

现代汉语二合复句内分句语气同类组配是主体,异类组配是次要的。前后分句语气异类组配的使用频率具有一定的倾向性：陈述与疑问／祈使／感叹的组配〉疑问／祈使／感叹之间的两两组配;陈述＋疑问／祈使／感叹〉疑问／祈使／感叹＋陈述。陈述语气与疑问／祈使／感叹共享特征的数量都多于疑问、祈使、感叹两两语气之间共享特征的数量,因此前者是优势组配。疑问／祈使／感叹居前时通常要满足三个条件,居后时不受此限制,因此疑问／祈使／感叹居后是优势组配。  相似文献   

Convergent genomic signatures of high-altitude adaptation among domestic mammals

Abundant and diverse domestic mammals living on the Tibetan Plateau provide useful materials for investigating adaptive evolution and genetic convergence. Here, we used 327 genomes from horses, sheep, goats, cattle, pigs and dogs living at both high and low altitudes, including 73 genomes generated for this study, to disentangle the genetic mechanisms underlying local adaptation of domestic mammals. Although molecular convergence is comparatively rare at the DNA sequence level, we found convergent signature of positive selection at the gene level, particularly the EPAS1 gene in these Tibetan domestic mammals. We also reported a potential function in response to hypoxia for the gene C10orf67, which underwent positive selection in three of the domestic mammals. Our data provide an insight into adaptive evolution of high-altitude domestic mammals, and should facilitate the search for additional novel genes involved in the hypoxia response pathway.  相似文献

Application of network meta-analysis in the field of physical activity and health promotion     

Xiwen Su  Daniel J. McDonough  Haitao Chu  Minghui Quan  Zan Gao 《运动与健康科学(英文)》2020,9(6):511-520

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献

论排球裁判员的“裁判意识”     

褚斌 《福建体育科技》2008,27(3):17-19

排球裁判员的“裁判意识”表现为：当在排球比赛过程中出现犯规情况时,裁判员是否进行判罚的一种感知、分析、判断、思维等心理和生理机能的综合反映过程。它的形成有一定的规律,需经历原始意识、运用意识、应变意识、控制意识等四个阶段,由低向高逐级发展,最终形成优秀的“裁判意识”。  相似文献
