周恩来的现代科学技术革命思想论析

学术界对于周恩来的科学技术思想研究已经取得了一批成果 ,而对周恩来现代科学技术革命思想的研究则十分薄弱。周恩来是中共领袖中对现代科学技术革命认识最早、阐发最系统的一位杰出代表。对于现代科学技术革命的迅速崛起 ,周恩来不是漠然置之 ,而是积极主动的正视它、探讨它。周恩来关于现代科学技术革命的思想 ,具有鲜明的前瞻性、务实性和创造性 ,是中国共产党人顺应历史潮流、勇于迎接时代挑战的重要思想结晶。     

云南剑川海门口遗址饱水古木降解的微观构造分析

文中采用扫描电镜(SEM)和透射电镜(TEM)对海门口遗址饱水古木进行降解机理分析。结果表明:古木细胞次生壁收缩严重并与胞间层分离;胞间层保存较完好,呈连续网状。说明古木纤维素和半纤维素降解相对严重,木质素降解相对较轻。古木主要是受细菌降解,通过SEM和TEM均可见明显的细菌腐朽特征。细菌首先侵入细胞腔,再通过S3层侵入细胞壁内部。细胞壁内由于降解而产生的空隙在几十到几百纳米之间。饱水古木也受到了一定程度的真菌降解,但这类真菌主要降解古木内淀粉等物质,对细胞壁物质降解能力差,主要是使古木变色。     

草香时节

一个雨季冷不丁从山顶奔涌而来,让一切润湿和记忆的神志又得以恢复。春天的记忆有些零乱,就像一个瘪嘴的老太太回味往年的旧事,有些断断续续,陈年的记忆夹杂着近年的事     

Do EU funds crowd out other public expenditures? Evidence on the additionality principle from the detailed Czech municipalities’ data

European Union (EU) funds flowing into budgets of public sector organizations of its member states should be additional to their nationally funded expenditures. To investigate this additionality principle systematically, we develop a new empirical method. Our main hypothesis is that some of the EU-funded projects are crowding out national public expenditures. Not being able to reject the hypothesis would be consistent with violating the additionality principle. To test the hypothesis, we examine how EU funding translates into actual spending of relatively comparable municipalities of the Czech Republic. We innovatively match the municipal authorities’ budgetary data on EU-funded expenditure projects with their other, nationally funded, expenditures. We find no systemic crowding out of national public expenditures by EU funds at the level of operational programmes in the Czech municipalities’ data, which is consistent with no evidence of violating the additionality principle. Nonetheless, going down to the municipal level enables us to show how the results can pinpoint individual cases of EU fund’s potential mismanagement in Czech municipalities. Overall, we provide the first evaluation of the additionality principle at the level of individual recipients of EU funds and in doing so we develop a methodological approach potentially applicable to other fund recipients.

夏时期岳石文化的铜器补遗——东夷式青铜重器之推考

海岱地区岳石文化出土的种类繁多的铜质小工具,尤其是合范冶铸的青铜镞和新出现的一些东夷式青铜礼器如鼎、鬲、甗、戈等,不仅体现了岳石文化较高的青铜冶铸水平,也反映了夏、商、夷三族文化之间的交流和融合。
