Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.  相似文献

利用信号检测论的方法对130名大学生的国家科技成就刻板印象进行研究。结果发现,被试对中国近现代及当代科技成就判断标准的自然对数值显著高于对中国古代、美国近现代及当代科技成就判断标准的自然对数值(p<0.001),同时,被试对中国古代、美国近现代及当代科技成就的判断标准自然对数值没有显著差异(p>0.05),从而证明了大学生群体中明显存在着国家科技成就刻板印象。进一步的含义表明,大学生对中国古代科技成就依然保持绝对的自信,对中国近现代及当代科技成就的自卑并没有显著改变。在被试对2005年中国科技竞争力在全球的排名进行估计时,高估的人数显著多于低估的人数(p<0.001),从而表明,大学生对中国当前及未来科技成就的自信心开始建立。  相似文献

Implicit theories of creativity provide an understanding of attitude towards among different populations, including students. Insights on how students see and define creativity might help to adjust educational settings and thus make it possible to provide students with better conditions to support their creativity. Although many studies have been conducted on creativity in different cultural settings, little is known on individualism or collectivism is connected to implicit theories of creativity. This study was carried out among secondary school students in Estonia and Russia to identify possible differences in how students from different cultural backgrounds (and varying in individualism and collectivism) define creativity. The results indicated that there were differences in how students from Estonia and Russia defined creativity: Although students from Russia tend to identify creativity more with novel ideas, students from Estonia defined creativity more in terms of self-expression (students from schools with Estonian as the language of instruction) and uniqueness (students from schools with Russian as the language of instruction). Implications and further research suggestions are discussed.  相似文献

This paper is a contribution to the debate on the current mission model of the church in Southeast Asia. Scholars from St Elizabeth University in Bratislava, Slovakia, have performed qualitative research to examine the present mission model in Cambodia. Research was conducted on a sample of Catholic missionaries who have worked in Cambodia for a longer period of time. On the basis of this qualitative study, we have outlined and proposed some characteristics for today’s mission model in that country. Features included and emphasized dialogue with Buddhism, formation of spiritually mature people, social promotion and social inclusion, community development, the shift in inculturation regarding value systems, working in small groups, and reconciliation between ethnic communities.  相似文献

This study investigated a conceptual model with two pathways, altruism and perceived spiritual support, leading to resilience among student volunteers following Hurricanes Katrina and Rita (H‐KR). Both strengths share the sense of deep connections. Parallel pathways with the two major constructs were estimated using structural equation modeling, adjusting for demographics and peritraumatic emotional reactions. The two indicators may have served as a protective mechanism for all volunteers despite differing racial/cultural backgrounds. The potential protection of these strength factors was mediated through optimism and hope. Resilience among minority volunteers was associated more with faith‐related strengths, as indicated in the relevant pathway that also contributed to their altruistic actions. The resilience of white volunteers, however, was directly associated with altruism, a strength that does depend heavily on religious beliefs. Further, the modification index suggested a direct path from race to depression.  相似文献

This paper presents an analysis of the rowing parameters of differently skilled rowers. The study focuses on technique dependency on stroke rate. Five elite, five junior and five non-rowers participated, and the biomechanics of rowing on an ergometer was analyzed at stroke rates of 20, 26 and 34 str/min. The results show that elite rowers use a similar, consistent rowing technique at all stroke rates, the technique of junior rowers follows similar principles, while the technique of non-rowers varies. Elite rowers’ stroke length, handle motion and body posture do not change with stroke rate while the ratio of stroke phases, maximum forces, stroke work and joint loadings are constant at the same stroke rate but dependent on stroke rate. Junior rowers with stroke rate change also the stroke length. In non-rowers the differences can be observed in the handle motion and body posture during the stroke, their stroke length changes with stroke rate while the ratio of stroke phases stays constant. Although different movement execution is evident and variable with stroke rate, non-rowers demonstrate a consistent pattern at the same stroke rate. On the basis of the results, the crucial parameters that differentiate elite, junior, and non-rowers are identified.  相似文献
