爱因斯坦传奇

[1]一个多世纪前,艾伯特·爱因斯坦最初在瑞士伯尔尼专利局工作。他在瑞士联邦技术学院的入学考试中不及格,便接受了评估发明创造的工作,因为有稳定的收入。[2]然而在1905年,他的发明令任何在专利局登记的专利都相形见绌。从3月到9月,他发表了5篇论文,其中任何一篇都能荣获诺贝尔奖。它们使我们对宇宙的理解发生了革命性变化。那年他26岁。[3]今年被命名为爱因斯坦年,以纪念这位物理学家取得这伟大成就100周年。没有人在如此短暂的时间内创造出如此重要和富有创意的著作。他论证了宇宙并不像它看上去那样。     

如何开展家长培训

残障儿童的父母．是孩子一生最好的教育者，因为他们在孩子成长的过程中无私奉献，恪尽责任。对那些有残障儿童的家庭而言．“知识就是力量”这句话就是真理。这些家长需要掌握关于残障症状的特点、教育治疗方案和策略等信息，以提升日常生活质量。家长们也想知道什么样的服务最适合孩子．如何获得这些服务．如何定位家长角色以确保孩子的进步．[第一段]

The influence of support and stress on maternal attitudes

OBJECTIVES: This study examines an expanded version of Belsky's (1984) multi-dimensional process model of parenting to determine whether changes in stress and support influence maternal attitudes during the first year of a child's life. METHOD: Data were collected from mothers of newborns eligible for Hawaii's Healthy Start program who had been randomly assigned to home visitation (n=108) or control (n=104) status. Multiple regression analyses were used to test hypotheses regarding the influence of change in contextual sources of support and stress on parenting attitudes as measured by the Child Abuse Potential Inventory (CAPI) Abuse Scale. A post hoc analysis of variance was conducted to explore interactions among the predictor variables and home visitation. RESULTS: Stress in the form of change in public assistance status led to more punitive parenting attitudes while increased support from the partner and from close associates emerged as significant predictors of less punitive parental attitudes. The exploratory analyses suggest that home visitation may moderate the impacts of stress and support on maternal attitudes. CONCLUSIONS: In line with Belsky's (1984) process model of parenting, increased stress adversely impacted maternal attitudes regarding physical punishment while increased support exerted favorable effects. The results also support further elaboration of Belsky's model including the expansion of marital support to include unmarried partners and the need to consider the impact of formal support sources on parenting.     

鳥类的干制

在生物学課堂教学中,直观教具的演示,是教学和教育工作中不可缺少的一部分。但生物教师却不能每一堂都能安排好必要的教具。这是由于教师不会自己制备教具的緣故。我从事各种直观教具,特别是对爬行类、鳥类与哺乳类动物的干制标本,已有十余年的經驗。本文將介紹应用40%的福尔馬林溶液注射于动物屍体的方法干制鳥类标本的经验。剥制法虽比干制法效果好一些,但时間需要较长;此外,剥制时所用的砒霜或砷酸钠这些毒物,往往有危險,而且这些毒物又不易买到。干制只需用福尔馬林,危險性少,而每个藥房也都可买到。干制不同于剝制,以后会干縮变小,但形狀颜色不变。在一定的保存条件(玻璃柜中)下和适当的保养(每一年撒上一层萘粉、六六六药剂等),干制标     

对医预科学校学习目标的建议

最近，美国医学院校协会（ＡＡＭＣ）发表了医学院校学习目标报告（ＭＳＯＰ）以协助各院校培养“能够满足社会需求”的新一代医生。两份ＭＳＯＰ报告总体上是鼓励开发医预科学校的学习目标，建立这种学习目标能确保这些未来的医学生较好地面对医学院校的课程，这些课程已经限定了他们在四年中所学的内容。那些不能在标准医学课程中扩展的教育要素能在本科生教育中予以提供，医预科教育也能包含这些内容，例如：通讯技能，写作和演讲；医学的心理社会方面内容，从伦理学到医患关系的延伸；统计学，包括介绍以证据为基础的医学的概论；信息学…

Developmental links of very early phonological and language skills to second grade reading outcomes: strong to accuracy but only minor to fluency

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.     

Recognition of facial emotions among maltreated children with high rates of post-traumatic stress disorder

OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis.
