21世纪大学转型初探

在过去的几个世纪里,美国的高等院校(colleges anduniversities)之所以具有巨大的弹性,能够适应新的社会需求,是因为美国的高等院校特别具有企业精神(entreprene-urial)。教学人员可以用十分灵活而又新颖的方式朝不同的目标迈进,他们不但有这样做的自由,而且这样做还受到鼓励和奖励。今天,在一个前所未有的变革时代,我们面临的挑战就在于利用这种能量和创造性,     

1918—1919年的德国革命

1918——1919年的德国革命是德国贵族地主和资产阶级的帝国主义的矛盾极端尖锐化的结果。它是在资本主义总危机时期,在伟大十月社会主义革命的求解放思想的巨大影响下,开展起来的。德国的政治危机在战争前几年本已成熟。因此,德国帝国主义者发动了世界大战,他们不仅妄想按照自己的利益来重新分割世界,而且还企图利用战争巩固自己的政权、预防革命的爆发。但是,发动战争的结果,使得帝国主义德国的社会经济发展起了变化,这就更促使了帝国主义德国内部矛盾进一步尖锐化。

教育科学与教师的创造

苏共二十七大和关于学校改革的文献明确地指出,必须发扬主动精神、创造精神,学习和推广先进经验,坚决克服因循守旧、故步自封的保守倾向。苏共中央的政治报告向党的代表大会指出,在对新事物漠不关心的状况还没有根本消除以前,应该特别重视具有创造性的主动精神、创造探索气氛、革新活动方式和方法。苏联学校和苏联教育学的出发点始终是列宁关于我们应该依据经过实践检验的成就,把事业推向前进,通过适当的检验,把地方的经验推广到全国去的著名论断。现在,为科学地总结教育创造成果创造了基本的新的有利条件,如对经验的实际方向进行有计划的研究,在统一的标准教学计划的基础上,对先进经验和各地教师的革新活动进行对比研究成为可能,并且有可能将先进经验加以大面积地推广。     

Genetic and environmental influences in adolescent peer socialization: evidence from two genetically sensitive designs

Harris argues that peer relationships are the chief determinants of personality development. Harris's thesis makes the behavioral genetic investigation of peer groups particularly timely. The present study examined genetic and environmental contribution to self-reported peer-group characteristics in two samples of adolescent siblings: 180 adoptive and nonadoptive sibling pairs from the Colorado Adoption Project, and 386 sibling pairs from the Nonshared Environment and Adolescent Development Study. Substantial genetic influence emerged for college orientation, with the remaining variance accounted for by nonshared environment. For delinquency, however, the majority of the variance was explained by nonshared environment. Although genetic influence was implicated for peer popularity in twin analyses, genetic factors were not important in explaining individual differences in nontwin siblings. These results suggest that although some dimensions of peers are somewhat mediated by genetic factors, nonshared environmental influence is substantial.
