不忘初心：基于央视宣传片百年政党多模态形象建构研究

央视形象宣传片《我是谁》是中国共产党建党95周年以来的首部公益广告,具有重要的时代意义和研究价值.结合视觉设计语法、评价理论和“宣传片”的图像、文本和声音语料建立“宣传片”多模态形象诠释框架,探索“宣传片”建构党的形象的过程与范式.研究发现:一是“宣传片”图像的再现意义体现接地气的创意理念,互动意义展现与受众间的平等权势关系,构图意义揭示青年群体是目标受众的精准定位;二是“宣传片”文本重点建构人际意义的协商语义,从客观视角而不是主观情感刻画党员群体爱岗敬业的务实作风和百年政党一心为民的赤子之心;三是“宣传片”音乐、旁白等声音能够有效增强受众全方位了解党的形象塑造,从而尽快接受党为人民服务的不变“初心”.     

Whitewashing the nation: racist jokes and the construction of the African ‘other’ in Greek popular cinema

This article explores representations of race in three Greek popular films of the 1970s and 1980s. The portrayal of African characters in these films is antagonistically positioned in relation to the dominant, ‘whitewashed’ Greek national narrative which relies on the nineteenth century idea that Greece is the progenitor of European civilization. Often masquerading itself as ‘just a joke’, the discourse of these films narrates the African Other as lacking in terms of culture, intelligence and beauty – the three central categories upon which the idea of the ‘white supremacy’, according to Cornell West, is historically constructed in modernity. Tightly woven with this idea (largely introduced in Greece by the leading European powers), these films enunciate explicitly colonial viewpoints in a country that was neither a colonial power nor at the geopolitical center of the European project. The article argues that the racialized representations of these films are an effect of appropriating the Eurocentric idea of historicism, where the ‘progress’ and ‘backwardness’ of groups and nations are measured according to how effectively they perform the values of modernity.     

From peaceful marches to violent clashes: a micro-situational analysis

Recent studies point to the relevance of situational factors in the emergence of violence. This paper applies these insights to a systematic analysis of how and why peaceful protest marches transform into violent clashes. It focuses on the micro-situational patterns and emotional dynamics during protests. The exploratory study compares 20 peaceful and violent protests of the Global Justice Movement in the United States and Germany. It employs a triangulation of visual data with document data. The study relies on in-depth qualitative analysis, based on the principles of process tracing. Findings suggest that in those protests where violence emerges, a prior micro-situational pattern is systematically visible. The discussion of exemplary cases shows that two emotional phases precede the outbreak of violence. These phases emerge in a specific temporal danger zone of 1–3 h after the start of a protest. Further, specific triggering moments seem to prompt the outbreak of violence, like the breaking-up of police–protester lines, actors being outnumbered, or falling down. The emotional dynamic between protesters and officers during a protest likewise influences the intensity of violence and how violent situations end. Consequently, the paper suggests that actors need to go through a confrontational micro-situation in a demonstration in order to be able to use violence.     

‘It’s better if someone can see me for who I am’: stories of (in)visibility for students with a visual impairment within South African Universities

Issues of visibility, invisibility and the non-disabled gaze are very relevant to the lives of many disabled persons. With this article we tentatively show that, despite the physical ‘over’-visibility of disabled bodies, many intricate parts of their personhood remain obscured and invisible. Interviews with 23 students with a visual impairment revealed that they sometimes experienced stares and averted gazes from their sighted counterparts. In response, they often hid their entire impairment, or parts thereof, in an effort to conform and gain acceptance and to earn membership to a non-disabled peer group. Acceptance was often found in companionship with fellow disabled peers. Since these stories told of continuing exclusion for disabled students on tertiary grounds, further participatory research is recommended.     

Accessibility of European museums to visitors with visual impairments

People who have visual impairments exceed 250 million persons worldwide and represent an important cohort of museum visitors. However, they experience many constraints to participation in daily life. Few studies analyse the accessibility of museums to visitors with visual impairments, and many are confined to a single museum and to a small set of strategies for improving accessibility. This article aims to identify a broad set of strategies to increase the accessibility of museums to visitors with visual impairments and analyse the accessibility of museums in four European cities. Conclusions and implications for policy-makers and museum managers, designed to promote the creation of inclusive museums, are presented.

Phase I monitoring and change point estimation of autocorrelated poisson regression profiles

The objective of this paper is to study the Phase I monitoring and change point estimation of autocorrelated Poisson profiles where the response values within each profile are autocorrelated. Two charts, the SLRT and the Hotelling's T², are proposed along with an algorithm for parameter estimation. The detecting power of the proposed charts is compared using simulations in terms of the signal probability criterion. The performance of the SLRT method in estimating the change point in the regression parameters is also evaluated. Moreover, a real data example is presented to illustrate the application of the methods.     

Evaluating Probabilistic Forecasts with Bayesian Signal Detection Models

We propose the use of signal detection theory (SDT) to evaluate the performance of both probabilistic forecasting systems and individual forecasters. The main advantage of SDT is that it provides a principled way to distinguish the response from system diagnosticity, which is defined as the ability to distinguish events that occur from those that do not. There are two challenges in applying SDT to probabilistic forecasts. First, the SDT model must handle judged probabilities rather than the conventional binary decisions. Second, the model must be able to operate in the presence of sparse data generated within the context of human forecasting systems. Our approach is to specify a model of how individual forecasts are generated from underlying representations and use Bayesian inference to estimate the underlying latent parameters. Given our estimate of the underlying representations, features of the classic SDT model, such as the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC), follow immediately. We show how our approach allows ROC curves and AUCs to be applied to individuals within a group of forecasters, estimated as a function of time, and extended to measure differences in forecastability across different domains. Among the advantages of this method is that it depends only on the ordinal properties of the probabilistic forecasts. We conclude with a brief discussion of how this approach might facilitate decision making.     

唯美与现实: 荷兰画派对《意中人》的文学化用

本文旨在分析哈代如何在《意中人》中借鉴17世纪荷兰画派进行文学创作。首先，看似“低俗生厌”的荷兰画派启发了小说的形式创造。哈代借用荷兰画派的手法和内涵融通了绘画与小说这两种不同艺术形式在再现现实主义思想上的一致性。其次，荷兰画派是《意中人》的想象来源之一。荷兰画派的意象、主题和类别被创造性地整合进《意中人》中，哈代借此表达了艺术取代上帝，以审美的态度应对人生的文学思想。     

Assessing direct and indirect seasonal decomposition in state space

The problem of whether seasonal decomposition should be used prior to or after aggregation of time series is quite old. We tackle the problem by using a state-space representation and the variance/covariance structure of a simplified one-component model. The variances of the estimated components in a two-series system are compared for direct and indirect approaches and also to a multivariate method. The covariance structure between the two time series is important for the relative efficiency. Indirect estimation is always best when the series are independent, but when the series or the measurement errors are negatively correlated, direct estimation may be much better in the above sense. Some covariance structures indicate that direct estimation should be used while others indicate that an indirect approach is more efficient. Signal-to-noise ratios and relative variances are used for inference.
