爱国主义歌曲作为对祖国抒发赞颂之情的歌曲,是“光荣颂”“欢乐颂”“祝福颂”的有机统一,是培育和践行社会主义核心价值观的重要载体。从精神价值而言,爱国主义歌曲具有社会公共性、历史恒久性、无比崇高性。高校开展咏唱爱国主义歌曲活动,能增进学生对祖国的自豪之情,提升其民族自信,激发其报国之志。高校开展咏唱爱国主义歌曲活动,即要精选优异的爱国主义歌曲音乐本体,又要注重发挥高校教师的带头作用,还要加强学校各级组织机构和辅导员队伍的引领作用。高校党政领导对这类歌咏活动要进一步提高认识站位、增强重视程度、加强条件支持。  相似文献

宋代共设有三等閤职,最初供职于閤门,后閤职官员出外任职情况变得普遍,直接推动了外任武官兼带閤职制度的发展,此后閤职作为武官兼带的一种职名,成为奖励军功以及控制武官的一种有效手段。而閤职制度的发展也使閤职作为武臣清选的地位逐渐确立,表现之一就是在磨勘叙迁上较一般武官而言具有一定的优越性。同时,内外不同的閤职在磨勘制度上也有一定的差异,这些差异的产生也加深了閤职作为武臣清选的内涵。  相似文献

We review theorizations of gendered anti-Blackness and the scholarship on the politics of belonging. Bridging together this literature, we propose gendered anti-Black non-belonging as an alternative framework for addressing African descendant women's expressions and realities of belonging in the United States and Portugal. We select these two cases for their remarkably distinct—yet related—racial ideologies of the state. In the United States, colorblindness is the main ideology of the state whereas in Portugal anti-racial ideology pervades. As we will highlight, the experiences of belonging among African descendant women in the United States and Portugal challenge the veracity of these racial ideologies which work to render gendered anti-Black oppression invisible. In both cases, anti-Black non-belonging means that African descendant women are vulnerable to gendered state violence and racist practices impacting their individual and group belonging; as a result, the right for Black bodies to be in a particular place and space is constantly contested, and, often, violently regulated and disciplined. Yet, anti-Black belonging is both a matter of oppression and resistance. African-descendant women draw from their everyday knowledge of domination to employ resistance. In doing so, as we will argue, they rewrite the national narrative of race, gender and belonging in Portugal and the United States.  相似文献

For many environmental processes, recent studies have shown that the dependence strength is decreasing when quantile levels increase. This implies that the popular max‐stable models are inadequate to capture the rate of joint tail decay, and to estimate joint extremal probabilities beyond observed levels. We here develop a more flexible modeling framework based on the class of max‐infinitely divisible processes, which extend max‐stable processes while retaining dependence properties that are natural for maxima. We propose two parametric constructions for max‐infinitely divisible models, which relax the max‐stability property but remain close to some popular max‐stable models obtained as special cases. The first model considers maxima over a finite, random number of independent observations, while the second model generalizes the spectral representation of max‐stable processes. Inference is performed using a pairwise likelihood. We illustrate the benefits of our new modeling framework on Dutch wind gust maxima calculated over different time units. Results strongly suggest that our proposed models outperform other natural models, such as the Student‐t copula process and its max‐stable limit, even for large block sizes.  相似文献

历史照亮过去,历史启迪未来。以党史、新中国史、改革开放史、社会主义发展史为核心内容的“四史”教育,是以历史为基础的思想政治教育。从党史、新中国史、改革开放史、社会主义发展史中挖掘思想政治理论课教育资源,对高校传承红色基因、落实立德树人根本任务具有重要的指导意义。以庆祝中国共产党成立100周年为契机,将“四史”教育融入高校思想政治理论课教学,必须遵循相应的逻辑理路:树立正确党史观、坚定理想信念的价值追求是融入的逻辑立场;强化大历史观、理解党的伟大贡献是融入的逻辑方法;坚持内在统一性、把握“四史”教育的整体性逻辑是融入的基本前提;抓住侧重点、精准对接各门大学生思想政治理论课程是融入的逻辑核心;坚持实践逻辑、引导大学生从“四史”中汲取智慧和力量是融入的根本遵循。  相似文献

随着电子商务的蓬勃发展,“通知—删除”规则在有效制止电子商务专利侵权中具有重要作用。我国在21世纪初引进“通知—删除”规则,逐步构建了适用于电子商务领域专利侵权的“通知—删除”规则。《民法典》正式施行以来,“通知—删除”规则在适用于电子商务专利侵权中暴露出诸多问题:存在规则滥用隐患,权利人与商家利益失衡,通知与反通知的审核标准难以一致,因错误通知造成商家损失难以恢复,等等。解决好这些问题,需从专利侵权的特殊性出发,贴合《民法典》第1195条的规定,遵循“通知—删除”规则的立法目的进行解释适用;应重视和探索电子商务平台的自治能力,推动“通知—删除”规则在电子商务专利侵权中的解释适用。  相似文献

墓志作为一种重要的出土文献,是研究当时社会、历史、文化、语言文字等的宝贵语料。目前,由于各种原因,现行墓志在校点方面仍存在诸多的问题。选取元代墓志为例,通过比照拓片,运用语言学、校勘学、文献学等方法,对其中的校点可商之处进行考辨,以还原墓志之原貌,促进墓志文献的研读。  相似文献

The socio-economic literature has focused much on how overall inequality in income distribution (frequently measured by the Gini coefficient) undermines the “trickle down” effect. In other words, the higher the inequality in the income distribution, the lower is the growth elasticity of poverty. However, with the publication of Piketty’s magnum opus (2014), and a subsequent study by Chancel and Piketty (2017) of evolution of income inequality in India since 1922, the focus has shifted to the income disparity between the richest 1% (or 0.01%) and the bottom 50%. Their central argument is that the rapid growth of income at the top end of millionaires and billionaires is a by-product of growth. The present study extends this argument by linking it to poverty indices in India. Based on the India Human Development Survey 2005–12 – a nationwide panel survey-we examine the links between poverty and income inequality, especially in the upper tail relative to the bottom 50%, state affluence (measured in per capita income) and their interaction or their joint effect. Another feature of our research is that we analyse their effects on the FGT class of poverty indices. The results are similar in as much as direction of association is concerned but the elasticities vary with the poverty index. The growth elasticities are negative and significant for all poverty indices. In all three cases, the disparity between the income share of the top 1% and share of the bottom 50% is associated with greater poverty. These elasticities are much higher than the (absolute) income elasticities except in the case of the poverty gap. The largest increase occurs in the poverty gap squared – a 1% greater income disparity is associated with a 1.24% higher value of this index. Thus the consequences of even a small increase in the income disparity are alarming for the poorest.  相似文献

The COVID-19 pandemic is impacting health systems worldwide. Maternity care providers must continue their core business in caring and supporting women, newborns and their families whilst also adapting to a rapidly changing health system environment. This article provides an overview of important considerations for supporting the emotional, mental and physical health needs of maternity care providers in the context of the unprecedented crisis that COVID-19 presents. Cooperation, planning ahead and adequate availability of PPE is critical. Thinking about the needs of maternity providers to prevent stress and burnout is essential. Emotional and psychological support needs to be available throughout the response. Prioritising food, rest and exercise are important. Healthcare workers are every country’s most valuable resource and maternity providers need to be supported to provide the best quality care they can to women and newborns in exceptionally trying circumstances.  相似文献

近代巴蜀诗人李士棻曾被曾国藩誉为“太白醉魂”,为曾府门下“四川三李”之一,其诗作有浓郁的巴蜀文化特色。然李氏仕宦不显,长期以来学界对其关注不足,学界近年不多的相关研究,多围绕国内所存的文献,对其诗歌创作进行艺术分析,对诗人的生平介绍多简单略过,没有严谨的考证,目前仍然很有争议。通过搜罗国内外现存典籍,综合目前所见李士棻本人著述,辅以晚清近代重要报刊《申报》和与李氏有交往的朝鲜文人文献,考证其生卒年及别号,冀为今后的相关研究解决基础问题。  相似文献
