为探讨褪黑素对内毒素血症山羊肝线粒体自由基代谢的影响,将48只山羊随机分为4组,生理盐水组(NS组)、内毒素组(LPS组,1 mg/kg)、褪黑素组(MT组,1 mg/kg)和褪黑素保护组(MT LPS组),每组分别在处理后第3和6 h各宰杀6只羊,取肝组织,提取肝线粒体,检测肝线粒体中超氧化物歧化酶(T-SOD)、总抗氧化能力(T-AOC)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GSH-Px)和谷胱甘肽还原酶(GR)活性及丙二醛(MDA)含量的变化。结果显示,内毒素血症时山羊肝线粒体中抗氧化酶的SOD、GSH-Px、GR和CAT活性降低,T-AOC活力下降,MDA含量明显增加,而褪黑素保护组肝线粒体抗氧化酶活性普遍回升,MDA含量明显下降。提示,褪黑素能减轻内毒素血症山羊因脂质过氧化造成的肝线粒体损伤,保护肝线粒体功能。 相似文献

大学英语评估系统的现状及改革建议 总被引:2,自引:0,他引:2
当前的大学英语教学评估系统包括三个子系统:基础阶段结束时的四、六级英语考试;各学期期末的学业考试;社会对大学生英语综合能力的需求和评价。但是,由于许多学校和用人单位都把四、六级考试作为考核的终极标准,导致现在的大学英语教学整个只是围绕四、六级考试进行,而四、六级考试本身又存在许多问题,造成了一种恶性循环;各学期期末的学业考试失去了其本身的意义,只是一种四、六级考试的模拟;学生也缺乏适当的途径去了解社会对英语运用能力的实际需求。这三个子系统对大学英语的教学产生了严重的负面反拨效应,要想对大学英语进行改革,首先就要从评估系统着手。 相似文献

This article is about civil society and state-centred struggles in contemporary Zimbabwe. I first identify and outline three current understandings of civil society. Two understandings (one Liberal, one Radical) are state-centric and exist firmly within the logic of state discourses and state politics. A third understanding, also Radical, is society-centric and speaks about politics existing at a distance from the state and possibly beyond the boundaries of civil society. This civil society-state discussion frames the second section of the article, which looks specifically at Zimbabwe. It details civil society as contested terrain (from the late 1990s onwards) within the context of a scholarly debate about agrarian transformation and political change. This debate, which reproduces (in theoretical garb) the key political society (or party) fault-lines within Zimbabwean society, has taken place primarily within the restricted confines of state-centred discourses. 相似文献

Political scientists generally agree that all individuals structure their cultural attitudes in the same unidimensional fashion. However, various populist radical right parties remarkably combine moral progressiveness with conservatism regarding immigration-related issues. This suggests that the structuring of cultural attitudes among the electorate may also be more complex than typically assumed. Applying Correlational Class Analysis to representative survey data, the study uncovers three cultural belief systems. For individuals adhering to an integrated one, all cultural attitudes are interdependent, as typically assumed. However, two alternative belief systems are also uncovered: intermediate and partitioned. In the latter, positions on one cultural attitude (e.g. ethnocentrism) are barely related to positions on others (e.g. rejecting Islam or opposing homosexuality). The existence of multiple cultural belief systems challenges the widely held assumption that all people organise their cultural attitudes similarly. Both political party agendas and individuals’ education level and religion appear key to understanding variation in belief systems. 相似文献

Since the 1980s, Western Europe has experienced the surge of populist radical right parties. In an attempt to ward off these electoral newcomers, established parties have pursued strategies of disengagement, such as exclusion and de-legitimisation. This study examines the electoral effects of an excessive form of de-legitimisation, which we label ‘demonisation’. We estimate the effects of demonisation on electoral support for the Dutch Freedom Party (PVV) and its predecessor Groep Wilders. Time series analyses show that demonisation has a negative effect on electoral support, but only for Groep Wilders. Once the populist radical right party has made a successful entry into the party system, demonisation does not have its intended consequences. 相似文献

Empirical studies have demonstrated that compared to almost all other parties, populist radical right (PRR) parties draw more votes from men than from women. However, the two dominant explanations that are generally advanced to explain this disparity – gender differences regarding socio-economic position and lower perceptions regarding the threat of immigrants – cannot fully explain the difference. The article contends that it might actually be gender differences regarding the conceptualisation of society and politics – populist attitudes – that explain the gender gap. Thus, the gap may be due, in part, to differences in socialisation. The article analyses EES 2014 data on voting for the populist radical right and the populist radical left in nine European countries. Across countries, the gender gap in voting for the PRR is indeed partly explained by populist attitudes. For populist radical left parties, the results are less clear, suggesting that populism has different meanings to voters on the left and on the right. 相似文献

The purpose of this paper is to discuss how fascism may be identified by its actions, the stages through which a fascist rule takes power, and how to recognize it before it does so. The thesis is that a fascist takeover of a democratic government is rapid and unexpected. Its goal is a revolutionary reversal of representative government in the name of the people, while it accomplishes the opposite: a single-party corporate regime that replaces individual liberty with subtle, bureaucratic, and overt types of coercion. Rather than generate a generic definition of the many types of fascism, it is more useful to study how it affects the lives of ordinary people, the milieu out of which it develops, and what its precursors look like. Understanding fascism entails studying it from the point of view of those who lived under it and recorded their experiences, as well as from the analytic perspectives of social scientists. As Robert O. Paxton observes: “The fascist phenomenon was poorly understood at the beginning in part because it was unexpected.”1 We are facing the question again in 2017 with the surprise election of Donald Trump as the forty-fifth president of the United States by a minority of the popular vote and the evident support of the white nationalist milieu. Paxton proposes a five-stage theory for understanding fascism in its many varieties. A developmental sequence is proposed against which current events in the United States may be assessed. 相似文献
