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.     

Factors that influence elementary school teachers’ attitudes towards inclusion of visually impaired children in Turkey

There is a scarcity of research on inclusion of visually impaired children in Turkey. Specifically, a gap exists concerning the attitudes of elementary school teachers towards the inclusion of visually impaired children in mainstream schools. This article uses data from two questionnaires, leveraging the responses of 253 teachers from rural and urban areas. The results demonstrate that elementary school teachers commonly hold positive attitudes towards the inclusion of visually impaired children and that teachers’ initial and in-service training about inclusion positively influenced their attitudes. Our findings are in contrast with earlier research which argues that teachers do not hold positive attitudes to inclusion, and highlights that a key barrier to inclusion stems from elementary school teachers feeling unprepared to teach visually impaired children. We conclude that greater post-qualification training is required to enable teachers to operationalise different approaches that facilitate the inclusion of visually impaired children.     

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.     

Young people's orientations to the future: navigating the present and imagining the future

This article discusses the findings of the Imagine Sheppey project (2013–2014) which studied how young people are ‘oriented’ towards the future. The aim and approach of the project were to explore future imaginaries in a participatory, experimental, and performative way. Working with young people in a series of arts-based workshops, we intervened in different environments to alter the space as an experience of change – temporal, material, and symbolic. We documented this process visually and made use of the images produced as the basis for elicitation in focus groups with a wider group of young people. In this article we discuss young people's future orientations through the themes of reach, resources, shape, and value. In so doing, we reflect on the paths that our young respondents traced to connect their presents to what is next, what we call their modes of present–future navigation. We explore the qualities and characteristics of their stances within a wider reflection about how young people approach, imagine, and account for the future.     

视觉权力反抗下的艾米丽

《献给艾米丽的一朵玫瑰花》引起了很多研究者的兴趣，但是，是谁以及为什么献给艾米丽一朵玫瑰花却没有定论。从视觉权力的角度分析这一问题，指出艾米丽作为个体的“被看者”在面对“看”所代表的集体权力时，表面采取了顺从，实际运用了最强烈的反抗，扭转了“看”与“被看者”的不平等关系，从而赢得福克纳的一朵代表敬意的玫瑰花。     

社会化网络3维用户界面设计分析与研究

为了寻找三维用户界面设计策略，在归纳2维（2D）与2．5维（2．5D）用户界面包含的内容与设计策略的基础上，从3维（3D）用户界面的交互任务、信息呈现和用户搜索行为三方面进行了分析，整合了用户需求、空间行为、空间任务，创新性地构建了面向真3D空间的“需求-任务-层次模型”，为3D用户界面的构建提供了新的思路。此外，从细节层面对3D用户界面具体设计原则进行分析，提出了“信息呈现设计矩阵”，对3D用户界面设计具有一定的指导意义。     

法律解释学的主观主义批评与哲学解释学的回应

认为哲学解释学把法律解释学引向主观主义陷阱并严重破坏了法律的确定性,这个批评是从制度之维和认识论之维展开的。制度之维的批评从中国司法制度不够完善反推法律解释学决不能借鉴带有主观主义色彩的哲学解释学;认识论之维的批评主张哲学解释学所说的事情本身不足以区分合理与不合理的前见,因而不能使法律认识有效地避开主观主义陷阱。然而,哲学解释学的经典文献《真理与方法》的相关内容证明了事情表现构成了前见合理与否的判准和法律认识的“证实”标准,从而对主观主义的批评构成了有力的回应。据此,法律解释学未来的发展方向应是一门以哲学解释学的本体论为基地的、隶属于法律认识论的法律解释学,而不是返回到以传统认识论为基础的法律解释方法学。     

摄影中的“新纪实”与“超现实”话语——以塞巴斯提奥·萨尔加多和杰瑞·尤斯曼为例

摄影是“自然之笔”与现实相对应。塞巴斯提奥·萨尔加多用镜头记录了真实的社会生活,其作品所表现的个体与群像在纪实品格外凸显出强烈的视觉美感和深刻性,形成了“新纪实摄影”风格;而杰瑞·尤斯曼的“超现实摄影”与前者相异,他用纯熟的后期暗房合成技术,通过底片叠加创造出现实中不存在的幻景,在具体与抽象之间拓展了作品的精神内涵和时空维度。文章以两位摄影大师为例,从三个维度来比较“新纪实摄影”与“超现实主义摄影”：“标记符”与“象似符”;“视觉寓言”;审美欲求。
