Reexamining Fear Appeal Models from Cognitive Appraisal Theory and Functional Emotion Theory Perspectives     

Jiyeon So  Kai Kuang  Hyunyi Cho 《Communication monographs》2016,83(1):120-144

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   

Investigation of iodine concentration in salt,water and soil along the coast of Zhejiang,China

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   

论中国共产党的执政基础     

旷为荣 《康定民族师范高等专科学校学报》2005,14(1):65-68

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   

初中物理二力平衡条件演示实验的改进     

邝昆武 《物理教学探讨》2002,20(1):25-25

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   

Genomic consequences of population decline in critically endangered pangolins and their demographic histories     

Jing-Yang Hu  Zi-Qian Hao  Laurent Frantz  Shi-Fang Wu  Wu Chen  Yun-Fang Jiang  Hong Wu  Wei-Min Kuang  Haipeng Li  Ya-Ping Zhang  Li Yu 《国家科学评论(英文版)》2020,7(4):798

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

高温用捆带冷轧原料使用性能评价     

黄菲  陶军晖  柳俊  匡伟  张兆丽  张建国 《黄冈职业技术学院学报》2015,(3):88-90

某客户外购了一卷冷轧原料,尝试进行高温用捆带的试制,委托对其进行性能评估,以确认该原料钢卷能否满足实际生产的需要,为后续是否批量采购提供科学依据。通过对该冷轧原料进行化学成分、微观组织、力学性能、表面质量和板形进行分析,可以确认其尽管还存在一些不足,但总体上仍能满足使用要求。同时,建议客户在批量采购前最好对产品的捆扎方式、应用对象、生产工艺和性价比进行全面考虑。  相似文献
