新中国战争电影是和新中国的成立、发展与变化密切联系在一起的,回眸上世纪半个多世纪中国战争电影所走过的历程,可以清晰地看到中国社会政治、经济、化发展变化的轨迹。从五六十年代的信念神话,到八九十年代的战争史诗,再到90年代中后期的战争传奇,中国战争电影始终与时代脉搏一起跳动,从而完成了自己的历史使命与艺术构建。  相似文献

Feelings of self-efficacy have been the object of several studies that have confirmed its ability to predict performance in different contexts. Yet few studies have been conducted using cognitive or academic tasks in which it is more difficult to clearly distinguish self-efficacy from competence. The present study aims to study the moderating role of cognitive capacity in determining the relationship between self-efficacy and on-line self-regulation observed while solving a verbal concept formation task. In order to distinguish self-efficacy from competence, 44 subjects were selected based on the results of their SSPI; these results of which are related to comprehension ability. Analyses of results allow us to observe that, when compared to subjects who consider themselves less efficacious, subjects who have strong feelings of self-efficacy have a higher success rate, are more certain of these successes and reject fewer correct hypotheses, no matter what their cognitive ability. These results once again bring to light the relative independance of cognitive ability and motivational determinants of a person’s actual accomplishments.  相似文献

新民主主义革命时期的学生运动是中国革命史的一个重要组成部分,它对中国革命起了先锋、桥梁作用,舆论宣传作用,支持配合推动作用。所以如此,是因为青年学生从爱国主义情感出发,顺应历史发展的潮流,听从党的召唤,服从党的领导,自觉担负起了救国救民的重任,自觉走上了与工农相结合的道路。  相似文献

Inhibitory control, the ability to restrain a prepotent but ineffective response in a given context, is thought to be indicative of a species’ cognitive abilities. This ability ranges from “basic” motoric self-regulation to more complex abilities such as self-control. During the current study, we investigated the motoric self-regulatory abilities of 30 pet dogs using four well-established cognitive tasks – the A-not-B Bucket task, the Cylinder task, the Detour task, and the A-not-B Barrier task – administered in a consistent context. One main goal of the study was to determine whether the individual-level performance would correlate across tasks, supporting that these tasks measure similar components of motoric self-regulation. Dogs in our study were quite successful during tasks requiring them to detour around transparent barriers (i.e., the Cylinder and Detour tasks), but were less successful with tasks requiring the production of a new response (i.e., A-not-B Bucket and A-not-B Barrier tasks). However, individual dog performance did not correlate across tasks, suggesting these well-established tasks likely measure different inhibitory control abilities, or are strongly influenced by differential task demands. Our results also suggest other aspects such as perseveration or properties of the apparatus may need to be carefully examined in order to better understand canine motoric self-regulation or inhibitory control more generally.  相似文献

At the end of Grade 4, 481 children on the Danish island of Bornholm were screened using group tests for sentence reading. For 205 of these children, language and speech data from the speech therapist's screening at age 3 were available, as well as language comprehension and linguistic awareness data from the kindergarten year (age 6) and word decoding measures in Grades 2 and 3. A path analysis revealed significant paths from early language abilities at age 3 through expressive and receptive language in kindergarten via language awareness in kindergarten and word decoding in Grade 2 to sentence reading in Grades 3 and 4. The subgroup of children with parents who had reported a history of reading problems at school entry scored significantly below average on sentence reading in Grade 4. The subgroup of children that were reported to show a very low interest in books and story reading before age 5 also scored low on sentence reading in Grade 4. Statistically significant but weak relationships were also found between parents' educational background, parents' library visits, and number of books at home and the child's reading ability in Grade 4.  相似文献

以IDSs和人工调查技术组合为例,通过构建博弈模型,分析了风险偏好对信息系统安全技术选择与配置的影响,认为组织风险偏好不仅影响着自身的策略也将影响对方的策略。研究结论显示风险厌恶型组织配置IDS数量并不总是高于风险中立型组织,组织风险偏好对其部署单IDS还是多IDSs甚至无直接影响。同时组织在黑客期望收益很低时对风险厌恶型黑客的人工调查率更高,而在黑客期望收益很高时其对风险中立型黑客的调查率更高。此外,黑客在组织人工调查成本较低时更倾向于入侵风险中立型组织,在人工调查成本很高时更愿意入侵风险厌恶型组织。  相似文献
