新形势下突发重大疫情网络舆论不仅给疫情防控带来了严峻挑战,而且给维护国家意识形态安全带来了较大压力。厘清网络舆论的生成逻辑,把握网络舆论发展的演进特征,对做好网络舆论引导与谣言治理意义重大。在现代网络社会,随着交往实践的普遍进行,从现实逻辑、实践逻辑与理论逻辑来看,突发重大疫情网络舆论的生成,是网络议题、网络交往和网络传播相互作用的结果。受网络社会交往实践主体、客体、环体和介体等多种因素影响,突发重大疫情网络舆论又呈现为非线性的发展演进趋势,极易引发“蝴蝶效应”造成舆论秩序失范,甚至导致“塔西佗陷阱”的舆论信任危机,给疫情防控带来复杂变数。必须建立健全网络舆论治理机制,有效管控舆情,提高疫情防控治理水平。 相似文献

This article discusses a form of lifestyle blogging where women blog about their homes and everyday lives. In these homing blogs, self-representations are characteristically spatially demarcated within the private sphere of the home. As these repeated representations of women in their homes take place in the public space of the internet, homing blogs work towards naturalizing the home as a women’s sphere. Written and commented on mostly by other women, homing blogs represent a feminine form of self-expression and communication that functions as a discursive expression of ongoing social, economic, and cultural changes in affluent Western societies. In this article, Finnish versions of these homing blogs are analysed in the cultural and political context of contemporary Finland, and discussed as a form of intimate publics that reverses the gender politics of other historical, semi-public spaces for the exercise of women’s agency, such as the salon. 相似文献

政府公信力是政府凭籍自身信用赢得公众信任的能力,十六大以来,党在施政理念上强调"以人为本",在执政行为上关注"民生";在绩效上彰显公平正义,施政方略渗透着人文关怀因素,政府公信力得到了有效提升。但由于腐败现象没有得到有效控制,党风廉政与制度化建设相对滞后,政府公信力也受到了冲击。在新一代领导集体治国理政中,"改革"成为新的常态,防腐败斗争与党风廉政建设取得了伟大成就,政府公信力的重振业已开启。 相似文献

This article examines the under-explored demand-side of active labour market policies (ALMPs). Based on interview data from a comparative study of the UK and Denmark, the paper analyses employers' perspectives and experiences of ALMPs. In both countries, employers were favourably disposed towards employing unemployed jobseekers but held negative views on conditionality. First, benefit conditionality led to employers receiving large numbers of unsuitable and unfiltered job applications, with associated negative resource impacts. Second, employers perceived this as a product of ‘box ticking' and compliance targets. Finally, employers criticised policy and media rhetoric for focusing solely on the supply-side and for problematizing unemployed candidates. The paper argues that these crucial, but neglected, employer perspectives demonstrate that the current benefit conditionality regime in the UK risks irrevocably ‘tarnishing' candidates, which undermines, rather than enhances, their chances of securing employment through ALMPs. This unique dataset provides further evidence that the current direction of policy requires urgent and radical re-thinking. 相似文献

AbstractThe problem of testing equality of two multivariate normal covariance matrices is considered. Assuming that the incomplete data are of monotone pattern, a quantity similar to the Likelihood Ratio Test Statistic is proposed. A satisfactory approximation to the distribution of the quantity is derived. Hypothesis testing based on the approximate distribution is outlined. The merits of the test are investigated using Monte Carlo simulation. Monte Carlo studies indicate that the test is very satisfactory even for moderately small samples. The proposed methods are illustrated using an example. 相似文献

Drawing from the theory of policy voting, this study examines the impact of opinions about gay rights on voting for presidential candidates. Qualitative analysis of the major party platforms and candidate campaign rhetoric from the six presidential elections held between 1988 and 2008 indicates that Democratic and Republican presidential candidates began openly expressing opposing positions on gay rights issues in 1992. Quantitative analysis of public opinion shows that, starting in 1992 and continuing through 2008, gay rights issues became more salient to the public, and opinions about gay rights began to exert a significant effect on vote choice. The study concludes with a discussion of the partisan forces that shaped the electoral significance of gay rights issues during the period from 1988 to 2008 and speculation about the role of gay rights issues in shaping future partisan electoral strategy. 相似文献

This paper proposes a new hysteretic vector autoregressive (HVAR) model in which the regime switching may be delayed when the hysteresis variable lies in a hysteresis zone. We integrate an adapted multivariate Student-t distribution from amending the scale mixtures of normal distributions. This HVAR model allows for a higher degree of flexibility in the degrees of freedom for each time series. We use the proposed model to test for a causal relationship between any two target time series. Using posterior odds ratios, we overcome the limitations of the classical approach to multiple testing. Both simulated and real examples herein help illustrate the suggested methods. We apply the proposed HVAR model to investigate the causal relationship between the quarterly growth rates of gross domestic product of United Kingdom and United States. Moreover, we check the pairwise lagged dependence of daily PM2.5 levels in three districts of Taipei. 相似文献

针对我国政府、企业和银行等金融机构共同关注的债转股问题,基于债务协商谈判思想,建立部分债务股权互换模型,计算公司证券价格,探讨了债转股对公司价值、破产概率、破产损失成本和资本结构的影响,给出了银行等债权人愿意债转股的充分条件。结果表明:在事先破产清算协议贷款下,事后全部债转股总能提高公司股权价值,但并不一定能提高债券价值。只有其协商谈判能力满足一定条件,公司债权人才愿意事后选择债转股,实现帕累托改进、提高社会福利水平。其次,在公司股东协商谈判能力的一定范围内,部分债转股能提高公司价值,其最优转股债息比例随着公司资产风险的增大而增加。再次,债转股能降低公司破产风险和破产损失成本,但同时也提高了债券风险溢价。最后,随着股东谈判能力增强,最优协商转股债务比例、杠杆率都减少,而债券风险溢价增大。本文所得结果对我国政府、企业和银行如何实施债转股提供理论参考和实践指导。 相似文献

基于2004—2017年中国省级面板数据,运用面板向量自回归(PVAR)模型,使用系统GMM估计、脉冲响应函数、方差分解以及格兰杰因果关系检验等方法分析了影子银行、地方政府债务及金融发展之间的动态关系.结果表明:影子银行、地方政府债务与金融发展水平三者之间存在动态耦合关系.在地方政府融资能力受到约束的情况下,影子银行为地方政府提供了多元的融资方式,在增加政府融资能力的同时提升了政府债务水平;而地方政府债务需求显著推动了影子银行规模的快速发展.同时,影子银行过度扩张危害了金融市场的健康发展,降低金融发展水平,继而使地方政府的融资渠道受到约束.但金融发展并不能有效约束影子银行规模,原因在于,政府融资需求是影子银行的主要动力,若不能控制地方政府的借贷行为则无法从源头解决问题.监管机构在去杠杆的过程中,应该综合考虑影子银行与地方政府债务、金融发展之间的动态关系,如此才能够实现预期的政策效果. 相似文献

Random effects regression mixture models are a way to classify longitudinal data (or trajectories) having possibly varying lengths. The mixture structure of the traditional random effects regression mixture model arises through the distribution of the random regression coefficients, which is assumed to be a mixture of multivariate normals. An extension of this standard model is presented that accounts for various levels of heterogeneity among the trajectories, depending on their assumed error structure. A standard likelihood ratio test is presented for testing this error structure assumption. Full details of an expectation-conditional maximization algorithm for maximum likelihood estimation are also presented. This model is used to analyze data from an infant habituation experiment, where it is desirable to assess whether infants comprise different populations in terms of their habituation time. 相似文献
