物理光学实验仿真平台的开发

为了提高学习者的学习兴趣和积极性,打破传统物理光学实验受时间和场地的限制,利用Matlab图形用户界面的设计与开发功能,制作了简洁美观、可拓展性强的物理光学实验仿真平台,实现了对多个经典光学实验的计算机仿真,包括光学拍、球面波干涉、杨氏干涉、等倾干涉、等厚干涉、夫琅和费衍射、菲涅耳衍射、光栅衍射、空间滤波、光的偏振和全息照相等.实验结果表明,该平台具有实验参数可灵活设置和良好的人机交换功能,并且通过mcc编译可以脱离Matlab环境使用.     

国际视野下的数字人文教育--基础设施视角的社区驱动型数字人文课程登记中心

数字人文以其新实践、新途径和新方法丰富了传统的人文学科领域。进入21世纪以来,暑期学校、研讨会和其他类似形式的教育活动普及了一系列与之相关的必备技能,以保证学生、学者们能够把握数字时代的新机会,同时世界各地推出了越来越多相关的学士和硕士项目。本文论述的焦点--数字人文课程登记中心(Digital Humanities Course Registry,DHCR)的创建就是为了展现全球日益兴盛的数字人文教育状况,其使命是广泛收集同类课程的资料,提供数字人文领域教学和培训的最新动态。文章探讨了数字人文这一新兴领域,并对CLARIN和DARIAH这两个欧洲基础设施进行介绍--它们是DHCR的共同运营者。文中还具体描述了DHCR的数据模型和数据管护流程,简要介绍其历史。利用DHCR实时数据,以定量方式描绘了数字人文教学的国际格局。     

偶是偶爸的小师爷

从东北老家来到南方上大学，学了个时髦的“电子商务”。当初爸妈一看到这名字就一个劲地点头叫好说肯定有前途．于是．我连这玩意到底学的是啥都不知道．就晕头晕脑地撞了进来。     

做那个最动听的音符

我家附近的徐师傅三四岁时得了麻疹,家里请师傅给他打灯火,他怕,乱动,结果打错了穴位.从那以后,他不幸得了面瘫,成了个面容丑陋的人.因为长相丑陋,他受到过很多人的歧视,上小学时被看不惯他的同学打落了牙齿;因为长相丑陋,他遭遇过很多不公平的待遇,有过几次失败的婚姻.长得丑陋不是他的错,因为丑陋而发生的很多痛苦他却不得不承受.     

小魔女韩冰在多哈神采飞扬

北京时间2006年12月3日21时，第15届（多哈）亚运会体操女子团体比赛开始角逐0最终，中国女队以239．400分卫冕成功，再度获得团体冠军。朝鲜、日本和韩’国女队分别位列第二、第三和第’四。在平衡木比赛过程中，一位身轻如燕的小女孩凌空一跃，以优美而标准的动作赢来观众的喝彩，获得该项比赛个人亚军。这个始终笑容可掬的“小魔女”就是中国体操运动员韩冰。     

高水平乒乓球运动员有力臂最大等长收缩力的评估

乒乓球是使用单侧上肢的一项运动,其特征是要进行重复多次高速且具爆发力的动作,无氧乳酸酵解代谢能力占有重要作用.研究对象与方法男女高水平乒乓球运动员(n=31).采用Takei5101握力计测量单侧上肢有力型和非单侧上肢有力型运动员的上肢最大等长收缩力.18名男运动员(平均年龄23.5±5.4岁)和13名女运动员(平均年龄21.3±3.3岁)均为西班牙乒乓球协会的国家联盟成员.采用SPSS v12.0 for windows和Excel v10.2软件包进行数据统计分析.研究结果发现无论男女运动员单侧上肢有力型的最大等长收缩力均高于非单侧上肢有力型,而左势手女运动员与右势手女运动员相比、右势手男运动员与左势手男运动员相比,单侧上肢有力型的最大等长收缩力均高于非单侧上肢有力型.研究还发现进攻型运动员与防守型运动员相比,单侧上肢有力型的最大等长收缩力高于非单侧上肢有力型.分析与讨论无论男女,单侧上肢有力型运动员手握力高于非单侧上肢有力型运动员.男性运动员比女性运动员的等长收缩力高,一个可以解释的事实是男性有更高的睾酮水平.肌肉力量不平衡可能发展成为脊柱侧弯姿态,这应该通过适当的力量和柔韧性训练来避免,以防止将来的运动损伤和运动成绩的下降.     

Maternal experiences of childhood abuse and intimate partner violence: Psychopathology and functional impairment in clinical children and adolescents

Objectives

The current study examined the independent effects of mothers’ childhood abuse (CA) and intimate partner violence (IPV) on psychopathology and functional impairment in children; and the potential moderating and mediating role of individual and family factors in these relationships. Additionally, this study explored the potential cumulative effects of both maternal CA and IPV on children's outcomes.

Method

The sample included 547 Spanish children and adolescents aged between 8 and 17 years, and their parents, who had accessed mental health services. The assessment was based on structured interviews with the children and their parents. Statistical analyses were carried out through hierarchical multiple, negative-binomial and logistic regressions, and Structural Equation Models.

Results

Children whose mothers experienced CA and those whose mothers suffered physical IPV showed increased DSM-IV disruptive disorders and externalizing behavior problems, respectively. Children who directly observed physical IPV and also suffered physical punishment by parents showed increased internalizing problems. IPV had effects, either direct or indirect by physical punishment, on children's externalizing problems. Cumulative effect analyses indicated that the prevalence of disruptive disorders was highest in children whose mothers had suffered both CA and IPV.

Conclusion

Spanish children whose mothers have suffered CA, IPV or both, are at high risk of serious conduct problems, whereas children exposed to IPV and who were also physically abused are at greater risk of internalizing problems. Physical punishment of children contributes in part to explain externalizing problems of IPV-exposed children. These findings indicate potential targets of assessment and intervention for families seeking help in mental health services.
