反垄断法视野中的买断式销售行为     

陈智能  蔡新艺 《宜宾学院学报》2006,6(3):15-17

买断式销售以生产商和销售商达成买断销售协议为基础。买断销售协议属于反垄断法中的纵向限制竞争行为。我国对买断销售行为应加以立法规制,建立以合理分析为原则,以市场结构标准为主要考察目标的规制买断式销售行为的法律制度。具体市场结构标准的确定,依赖于我国政策和经济发展不同阶段的需要,并由反垄断法执法机关在实践中不断地作出调整。  相似文献

Exploring revictimization process among Turkish women: The role of early maladaptive schemas on the link between child abuse and partner violence     

《Child abuse & neglect》2016

The purpose of the current study is to explore the revictimization process between child abuse and neglect (CAN), and intimate partner violence (IPV) based on the schema theory perspective. For this aim, 222 married women recruited in four central cities of Turkey participated in the study. Results indicated that early negative CAN experiences increased the risk of being exposed to later IPV. Specifically, emotional abuse and sexual abuse in the childhood predicted the four subtypes of IPV, which are physical, psychological, and sexual violence, and injury, while physical abuse only associated with physical violence. To explore the mediational role of early maladaptive schemas (EMSs) on this association, first, five schema domains were tested via Parallel Multiple Mediation Model. Results indicated that only Disconnection/Rejection (D/R) schema domains mediated the association between CAN and IPV. Second, to determine the particular mediational roles of each schema, eighteen EMS were tested as mediators, and results showed that Emotional Deprivation Schema and Vulnerability to Harm or Illness Schema mediated the association between CAN and IPV. These findings provided an empirical support for the crucial roles of EMSs on the effect of revictimization process. Clinical implications were discussed.  相似文献

三峡大老岭植物区系的垂直梯度分析     

沈泽昊  张新时  金义兴 《中国科学院研究生院学报》2001,39(3):260-268

为探讨山地植物区系构成特征及其垂直梯度的生态意义，根据对三峡大老岭地区植被垂直样带 调查获得的植物区系资料，分析了该地区植物区系成分构成的基本特征及其随海拔梯度的变化趋势，寻找了区系平衡点的位置；并利用聚类方法分析了山地气候垂直分异对区系成分构成的影响。结果表明：①大老岭植物区系具有温带性质，但仍反映了与热带区系的历史联系，有强烈的区域性；②属的分布区类型可归为热带分布、温带分布、地中海—中亚中心和东亚中心4组，各组区系成分的垂直梯度特征不同；热带、亚热带成分与温带成分的平衡点大致位于海拔650m；③区系成分构成和属的物种数量构成的聚类分析结果一致显示了植物区系构成与山地气候和植被垂直带相对应的格局。  相似文献   

科学技术——人类社会文明进化的基因组图谱   总被引：4，自引：1，他引：4  

沈律 《科学学研究》1999,17(4):20-30

人类社会就象生物和人类自身一样同样具有生命现象,同样具有新陈代谢,生殖发育,遗传变异,进化分化等生命现象,我们把这种生命现象称之谓类生命现象。本文就是从人类社会的类生命现象入手,对人类社会文明发展的遗传基因组———“科学技术体系”进行全面系统地研究,并根据生物遗传学原理和生物类比方法发现并提出了“科学技术遗传信息传递的中心法则”以及“科技规范因子（ 基因） 的自由分离组合规律”和“科技遗传信息的矩阵分布规律”。据此对人类社会文明的遗传与变异、进化与分化的本质性问题进行了初步分析  相似文献   

The effect of event repetition on the production of story grammar in children's event narratives     

Feltis BB  Powell MB  Roberts KP 《Child abuse & neglect》2011,35(3):180-187

Objective

This study examined the effect of event repetition on the amount and nature of story-grammar produced by children when recalling the event.

Method

Children aged 4 years (N = 50) and 7 years (N = 56) participated in either 1 or 6 occurrences of a highly similar event where details varied across the occurrences. Half the children in each age and event group recalled the last/single occurrence 5-6 days later and the other half recalled the last/single occurrence after 5-6 weeks (the final and single occurrence was the same). Children's free recall responses were classified according to the number and proportion of story-grammar elements (Stein &; Glenn, 1979—setting, initiating event, internal response, plan, attempt, direct consequence, and resolution) as well as the prevalence of causal links between the individual story-grammar elements.

Results

More story-grammar detail and more links between individual story-grammar elements were reported about the final compared to single occurrence. The amount of story-grammar increased with age and decreased over time. Further, an interaction was revealed such that the effect of retention interval on the production of story-grammar was negligible for older children who experienced the repeated event.

Conclusions

Event repetition has a beneficial effect on the production of children's story-grammar content in situations where event details varied from occasion to occasion. This study highlights the importance of eliciting free recall when conducting evidential interviews with child witnesses about repeated events.  相似文献

Enhanced monitoring accuracy and test performance: Incremental effects of judgment training over and above repeated testing     

《Learning and Instruction》2020

From a self-regulated learning perspective, adequate monitoring of own learning processes and outcomes is crucial to regulate one's own learning effectively. Research on metacognitive judgments, however, clearly indicates that students frequently overestimate their actual performance. Therefore, the present study with N = 209 undergraduate students aimed to support students in developing accurate judgments in order to improve learning processes and, eventually, performance. A quasi-experimental design with three conditions (metacognitive training, testing, and control) and five testing sessions was implemented. In addition to repeated testing plus individual feedback in the testing group, students in the metacognitive training group received psychoeducation, made item-specific judgments, and were given feedback. Over and above the positive effects of repeated testing, metacognitive training positively influenced several monitoring accuracy scores (bias, absolute accuracy, and specificity) and students' performance. Moreover, the metacognitive training group exhibited a nonlinear interindividual decrease in overconfidence. Overall, the study provided considerable evidence that monitoring accuracy and performance can be improved by means of judgment training.  相似文献
