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

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.     

民国初年梁启超拥袁与反袁的政治思想演化论析(下)

民国初期，梁启超由拥助袁世凯到反对袁世凯，乃是一个思想演进过程，梁袁思想的分歧主要体现在两个方面；一是立宪政治与独裁政治的分歧，二是爱国与卖国的分歧。梁氏的战斗檄文《异哉所谓国体问题者》的发表，是他高举反袁复辟帝制义旗的标志。     

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.     

论中国共产党的执政基础

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。     

初中物理二力平衡条件演示实验的改进

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     

有关电子文献著录情况的调查与建议

选取316种自然科学核心期刊为样本,就有关电子文献著录情况进行调查.结果显示,对GB/T 7714-2005《文后参考文献著录规则》的宣传力度不够,执行该标准的期刊很少,执行情况也很不好.建议期刊社多途径宣传这一国家标准,并尽快执行.     

Building a just world: the effects of service-learning on social justice beliefs of Chinese college students

This study aimed to examine the effects of different service experiences on the social justice beliefs of 60 Chinese college students with mixed methods. The quantitative results indicated that the participants in two service groups (i.e. for at-risk adolescents and adolescents with cerebral palsy) demonstrated a more significant promotion of social justice beliefs than their peers in non-service group. A qualitative analysis provided evidence of the mechanism underlying service-learning, as well as different service experiences affecting on students’ social justice beliefs. Finally, the implications for implementing service-learning and realizing social justice goals in China were discussed.
