王明、周恩来关于武汉保卫战的认识既有共同点，又存在根本的差别。二人都认为必须保卫武汉，但对保卫武汉重要性的认识程度和保卫态度上有不同；都认为国民党军队抗战极为重要，但在联合的策略以及发动人民、发动敌后抗日游击战的认识上有异；都认为坚持统一战线不可动摇，但在如何利用身份具体开展工作的方式方法上有别。周恩来、王明关于武汉保卫战认识的差异，是二人能否及时、准确、全面有效理解党中央方针政策的反映。 相似文献

云南护国运动在中国民主革命进程中所产生的巨大作用及其光荣的历史地位,中外历史学家早有定论.但对护国运动的若干史实,以及主要领导人物唐继尧的评价等问题,至今仍众说不一.经考证认为:护国运动并非蔡锷到滇才开始;护国运动选择云南是历史的必然;唐继尧与蔡锷在护国运动中均发挥了非常重要的历史作用. 相似文献

篮球比赛中防守假动作的应用 总被引：5，自引：0，他引：5
徐宏侠 《辽宁科技学院学报》2005,7(2):61-62
防守中的假动作,就是运用智慧,埋设陷井,巧妙的运用防守假动作、引诱对手达到完成防守的目的,加强防守的攻击性.防守假动作的出现弥补了防守技术上的不足,但在临场运用时要注意协防中假动作的运用.只要合理的运用防守的假动作就能摆脱防守的被动局面,提高防守的主动性. 相似文献

目的:通过探讨当今世界高水平足球比赛中后腰技战术的运用和规律,分析双后腰打法的技战术特点及影响因素,为今后在后腰技战术引用上提供一定的理论依据.方法:采用文献资料、录像观察等方法,主要以南非联合会杯四强球队的后腰队员技战术打法特点为研究对象.结论:1)进攻型后腰技术特点:在中场控球时间明显多于在前、后场,作为球队进攻的策划者其主要责任在于梳理球队中场,明确进攻方向;必须具备准确的传球率、较强的耐力素质;跑动范围主要集中在中场,而攻击力强的队伍,其位置偏向于中前场;跑位意识、补射意识以及大范围转移意识至关重要.2)防守型后腰技术特点:有效的抢断、铲球、破坏球、良好的耐力素质是防守型后腰最应具备的要素;应具有突出的补位、协防意识. 相似文献

Bullying is a form of interpersonal trauma that impacts all parties involved, including the youth who witness the bullying. Some bystanders choose to intervene and defend the child being bullied. Defending may be positively associated with psychosocial difficulties because youth are becoming more involved in a traumatic event, or because youth may be actively coping with the distress elicited from witnessing bullying; however, the link between defending and psychosocial difficulties has not yet been examined. The current study investigated the age-related differences and psychosocial difficulties associated with defending behaviour in school bullying. Data were collected from 5071 Canadian youth from Grades 4–12. Participants completed an online survey at school, which assessed demographic information, recent defending behaviour, location and frequency of witnessing bullying, and psychosocial difficulties (internalizing, anger, psychosomatic, academic, and relationship difficulties). A subsample of 1443 pure bystanders (no current bullying involvement) was used for regression analyses. Defending behaviour was more common among girls and among younger students. For boys, defending behaviour was associated with more psychosocial difficulties compared to boys who only witnessed the bullying. This relationship was less consistent for girls. Defending behaviour was also associated with more psychosocial difficulties at high levels of bullying exposure. These associations suggest that defending may come at a cost for youth, or that youth are defending their peers to cope with negative emotions associated with witnessing interpersonal trauma. More longitudinal research is needed to clarify these associations. 相似文献

In the present study, we tested the mediating role of moral disengagement in the effect of childhood maltreatment on bullying and defending. We also examined whether the mediating effect of moral disengagement differed between girls and boys, early and middle adolescents, as well as only and non-only children. Five hundred and fifty-two Chinese adolescents participated in this study. The results indicated that the prevalence rates of physical abuse, physical neglect, emotional abuse, and emotional neglect were 4.0%, 40.0%, 10.5%, and 27.9%, respectively. Path analysis showed that moral disengagement partially mediated the relation between childhood maltreatment and bullying, but did not mediate the relation between childhood maltreatment and defending. Moreover, multi-group analyses indicated that no significant path in the final model differed by gender. However, early adolescents exposed to high levels of childhood maltreatment were more likely to engage in bullying and less likely to engage in defending than middle adolescents, and early adolescents with high levels of moral disengagement were more likely to engage in bullying than middle adolescents. Compared to non-only children, only children exposed to high levels of childhood maltreatment were more likely to score higher on moral disengagement and less likely to engage in defending. 相似文献

高水平足球赛形成射门的防守过程模型研究 总被引：6，自引：0，他引：6
运用标记法、因子分析法对第16届世界杯足球赛和第10届欧洲杯足球赛形成射门过程的62项防守指标进行统计和分析，从而建立了形成射门的防守过程模型。结果发现高水平足球赛形成射门的防守过程模型主要有：“中场后撤防守盯人不紧被射门”、“中前场逼压、反抢被射门”、“角球、底传中抢点失利被射门”、“逐步防守被射门”和“被任意球射门”等因子模型。为我国足球训练提供理论参考依据。 相似文献
