“社会教育”传入中国考略

“社会教育”是20世纪初由日本传入我国的一个全新的教育名词,中国近代社会教育观念的产生与发展是受日本与德国社会教育双重影响的结果,在晚清后10年中,社会教育已经形成了一种教育思潮,并直接影响了民国教育部社会教育育司的成立和后来的各种社会教育实践活动。     

关于马克思主义经济学在中国演进的几个重要问题的思考

马克思主义经济学自从19世纪中叶创立以来一直处在演进之中,在中国的演进是从党的十一届三中全会以来改革开放中进行的。它必将导致中国社会主义经济学的建立。由于受过去传统的“苏联范式”经济学教条化、片面化的影响,以及现代西方经济学的冲击,理论界已出现了怀疑,甚至否定马克思主义经济学基本范式的倾向。笔者在此仅就经济学基本范式的几个重要问题谈谈自己的看法。

Criminal justice outcomes of prosecution of child sexual abuse: A case flow analysis

This study examined the progress and disposition of child sexual abuse cases referred for prosecution in four urban jurisdictions. Most cases were accepted for prosecution. The vast majority of cases carried forward for prosecution resulted in guilty pleas. Only 9% of the total sample went to trial. A majority of the small number that went to trial were convicted. Over 3/4 of those convicted were incarcerated. The rate at which cases were carried forward for prosecution and convicted was comparable to that of a national sample of felony arrests overall, but child sexual abuse cases were more likely to go to trial (p < .005) and received more severe sentences (p < .005). Our results are strikingly consistent with those from previous studies of prosecution of child sexual abuse. A new understanding of prosecution of child sexual abuse is recommended that takes into account the large proportion of cases that do not go to trial.

高校教师学术创业对科研产出的影响——基于倾向值匹配的反事实估计

高校教师学术创业对科研产出的影响一直是国内外争论的焦点。通过收集我国四所“双一流”大学教师学术创业的数据,运用倾向值匹配法探究高校教师学术创业与科研产出之间的因果关系。研究得出如下结论：高校教师参与学术创业后,科研产出数量不会发生变化,但科研产出质量会有所下降;不同学科教师学术创业对科研产出的影响效应存在异质性,工科类教师学术创业对科研产出数量和质量均无显著影响,而理科类教师学术创业对科研产出质量存在显著的负向影响。基于此,为了减少冲突,实现“研创”共生,建议建立“支撑保障”与“边界限制”并行的学术创业管理体制,并根据不同学科的特点进行分类管理。     

Reputation disparity in teaching and research productivity and rewards in the context of consequences of institutionalization of Publish or Perish culture in academia

The reputation disparity between teaching and research has stirred up an unending debate. The age-long notion that teaching and research overlap has become a controversial issue in academia. Consequences of the institutionalization of Publish OR Perish (POP) abound in the literature. This paper investigates the reputations disparity between teaching and research productivity and the rewards for these academic activities. It explores which, out of teaching activities and research publications receive higher or less attention and rewards. Relevant existing literature was reviewed to establish the institutionalization of POP and its consequences of the reputations disparity between teaching and research and its adverse effects on these activities. Evidence from the literature reviewed reveals the existence of POP reputation disparity as part of its consequences. A key finding is that teaching activities are insignificant and unrewarded as research publications. Neither the effectiveness nor the number of teaching loads counts like the numbers of publications.
