江泽民同志在庆祝中国共产党成立80周年大会上的讲话是马克思主义的纲领性文献。“七 一”讲话不仅充满着辩证唯物主义和历史唯物主义的基本观点,而且在继承马克思主义、毛泽东思 想、邓小平理论的基础上,丰富和发展了马克思主义理论,在许多重大问题上创造性地提出了新思 想、新观点、新论断,为我们树立了马克思主义理论创新的光辉典范。  相似文献

A pivotal claim in research on citizen competence is that the typical citizen knows very little about politics. Public opinion surveys provide a considerable body of evidence in support of this position. However, survey protocols with respect to factual questions about politics violate established norms in psychometric research on educational testing in that don't know answers are encouraged rather than discouraged. Because encouraging don't know responses potentially confounds efforts to identify substantive understanding, this practice may lead to the systematic understatement of political knowledge. We explore this possibility with data drawn from three split-ballot tests: one conducted as part of a survey in the Tallahassee, Florida, metropolitan area, one conducted as part of the 1998 NES Pilot, and one conducted as part of the 2000 NES. Results reveal that the mean level of political knowledge increases by approximately 15% when knowledge questions are asked in accordance with accepted practices in educational testing.  相似文献

用产毒素多杀巴氏杆菌单独接种到未作任何处理的仔猪鼻腔,细菌被迅速清除,鼻甲骨不发生明显萎缩。对仔猪鼻腔用1%醋酸预先处理2天后,再接种产毒素多杀巴氏杆菌,该菌则可在鼻腔长期定居,引起严重的鼻甲骨萎缩;如再混合感染支气管败血波氏杆菌时,猪萎缩性鼻炎的病理变化和临床指征明显加重。试验结果表明,与支气管败血波氏杆菌一样,某些非传染因素也可促进产毒素多杀巴氏杆菌在猪鼻腔定居,从而导致持续性萎缩性鼻炎的发生。  相似文献

The aftermath of the 2008 general election saw a series of upheavals occur in the Malaysian political landscape, not least of which was the emergence of a so-called “new politics.” Driven primarily by concerns over issues of public governance, this politics contained a set of interrelated questions involving changing notions of legitimate political authority. Although much has already been written about whether or not the post-2008 changes to Malaysia's socio-political terrain are genuine and enduring, I argue that many such analyses are too narrow in scope and fail to adequately recognise the complexity involved in such social realities. By distinguishing between the images and practices of the Malaysian state, this article aims to highlight the dynamic, contingent and contested nature of processes of legitimation. A detailed investigation of the consensus/dissensus surrounding Prime Minister Najib Razak's concept of 1Malaysia as the basis of a collective national identity reveals a more fundamental contestation occurring within contemporary Malaysian politics and society over the source(s) of political and moral legitimacy. While the opposition's challenge to Najib's administration remains formidable, of more pressing concern to Najib might be the objections arising from within his own party over the direction in which he is taking them. To define the present horizon of socio-political possibilities in Malaysia it is not enough, therefore, to simply explain how legitimation occurs; we must also be able to account for the way(s) in which it can occur.  相似文献

Slimming cactus (Hoodia), found only in southwestern Africa, is a well‐known herbal product for losing weight. Consequently, Hoodia extracts are sought‐after worldwide despite a CITES Appendix II status. The failure to eradicate illegal trade is due to problems with detecting and identifying Hoodia using morphological and chemical characters. Our aim was to evaluate the potential of molecular identification of Hoodia based on DNA barcoding. Screening of nrITS1 and psbAtrnH DNA sequences from 26 accessions of Ceropegieae resulted in successful identification, while conventional chemical profiling using DLI‐MS led to inaccurate detection and identification of Hoodia. The presence of Hoodia in herbal products was also successfully established using DNA sequences. A validation procedure of our DNA barcoding protocol demonstrated its robustness to changes in PCR conditions. We conclude that DNA barcoding is an effective tool for Hoodia detection and identification which can contribute to preventing illegal trade.  相似文献

The advocacy coalition framework (ACF), a unified framework for understanding the policy process, has been applied in various countries and regions; however, there are few contributions from Japan, despite seemingly favorable conditions for applying it. An exploration of what hinders ACF applications in Japan is worthwhile for developing the ACF as a framework for comparative policy process studies across various social and political settings. Therefore, this study aims to systematically review previous Japanese ACF studies. Our review found that Japanese ACF studies are fewer in number, have less coverage of policy fields, and have less methodological diversity and transparency than international trends. While most of the Japanese ACF studies supported the basic hypotheses of the ACF, we found a need to refine some hypotheses and research methods of the ACF studies. We also discuss the background factors in the inactivity of ACF studies in Japan and suggest solutions for it.  相似文献

目的研究日常活动中不明原因猝死(suddenunexpecteddeath,SUD)者NOSlAP基因的单核苷酸多态性。方法收集60例一般日常活动中SUD病例心血样本作为SUD组,另外随机抽取80例无关个体的外周血样本作为对照组,提取基因组DNA,用特异性引物对NOSlAP部分SNP位点(rsl0494366、rsl0918859、FSl2143842、rsl2742393、rs3751284、rs348624)进行PCR扩增和直接测序,计算等位基因频率和基因型频率.并分析各SNP位点在SUD组与对照组之间的差异性。结果NOSlAP第6外显子区域的rs3751284位点的等位基因频率和基因型频率在两组人群中的差异均有统计学意义(P〈0.05)。rs3751284位点的最小等位基因的频率在SUD组为0.325,在对照组为0.475。结论rs3751284位点可能是SUD的易感基因位点。  相似文献
