OA期刊出版模式下的版权平衡——Zwolle原则及其应用分析 总被引:8,自引:0,他引:8
开放存取运动其实质是寻求学术交流领域的利益平衡.Zwolle原则是一个支持学术界进行积极有效的版权管理的一般性原则,对于OA期刊出版中的版权平衡具有积极的指导意义.借鉴Zwolle原则,应从权利配置、版权管理和利益协调三方面着手以实现OA期刊出版模式下的版权平衡. 相似文献

Recognizing inconsistencies between the extant fear appeal theories and emotion literature, this research integrated cognitive appraisal theory and functional emotion theory into a fear appeal literature and proposed a model that describes a process through which both fear and anxiety can contribute to adaptive responses. Findings from an experiment (N = 927) supported the predictions. Fear and anxiety emerged as distinct constructs. Perceived susceptibility was a stronger predictor of anxiety than fear, while perceived severity was a stronger predictor of fear than anxiety. In addition, greater fear and anxiety led to greater response efficacy through increased motivation to obtain protection-related information and heightened attention to such information, thus mediating the threat and coping appraisal processes. The SEM model testing the predictions showed that perceived susceptibility had the strongest total effects on protection intention, followed by anxiety, perceived severity, and fear. 相似文献

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6~84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P<0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P<0.01). (3) Soil iodine value was 0.11~2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution. 相似文献

为了提高党的领导水平和执政水平,必须巩固党的执政基础。本文着重讨论了巩固党的执政基础的三个方面:深厚而广泛的群众基础是中国共产党永葆执政地位的力量源泉;严格而有力的组织基础是确保中国共产党执政地位的根本政治保证;与中国时代特征相结合的马克思主义理论基础是确保中国共产党执政地位的内在要求。 相似文献

在现行的初中物理二力平衡条件中,演示实验存在以下的不足:首先实验是在水平桌面上进行,不利于学生是观察实验现象;直接影响了实验的演示效果。其次是在水平桌面上的小车所受的力不是两个力,而是多个力,有重力、支持力、两个拉力、如果小车运动或有运动趋势,还必须考虑摩擦力。在教学中不好处理这个问题,只讲小车受到的两个拉力而不全面分析小车的受力,这不符合实际,对于具有一定思考 相似文献

语言性别歧视在现实中大量存在,它固化性别歧视观念,构建女性思维模式,束缚女性自身发展,也不利于两性关系和社会和谐发展。语言性别歧视并非能随社会的发展而自然消失,我们必须构建非性别歧视文化氛围,修改性别歧视语言。 相似文献

Pangolins are among the most critically endangered animals due to heavy poaching and worldwide trafficking. However, their demographic histories and the genomic consequences of their recent population declines remain unknown. We generated high-quality de novo reference genomes for critically endangered Malayan (Manis javanica, MJ) and Chinese (M. pentadactyla, MP) pangolins and re-sequencing population genomic data from 74 MJs and 23 MPs. We recovered the population identities of illegally traded pangolins and previously unrecognized genetic populations that should be protected as evolutionarily distinct conservation units. Demographic reconstruction suggested environmental changes have resulted in a population size fluctuation of pangolins. Additionally, recent population size declines due to human activities have resulted in an increase in inbreeding and genetic load. Deleterious mutations were enriched in genes related to cancer/diseases and cholesterol homeostasis, which may have increased their susceptibility to diseases and decreased their survival potential to adapt to environmental changes and high-cholesterol diets. This comprehensive study provides not only high-quality pangolin reference genomes, but also valuable information concerning the driving factors of long-term population size fluctuations and the genomic impact of recent population size declines due to human activities, which is essential for pangolin conservation management and global action planning. 相似文献
