癌症如何被呈现？——基于优酷网肺癌视频的内容分析

网络视频已成为重要的内容传播方式,但现有研究少有关注其对疾病的呈现方式与呈现特征。通过确定入选标准和内容编码,对优酷网跨度10年的220个肺癌视频进行分析。研究表明,视频普遍存在信息不权威、不科学与不充分现象。自媒体和非专业的个体是视频发布主体,科学的筛查建议、社会支持、患者实际生存状态等内容极少出现,不同发布来源在健康信念模式要素呈现上存在显著差异。为此,建议加强对媒介平台的融合使用,强化信息呈现形态与内容设计,加强网络平台的内容审核等。     

20 years of Bologna - a story of success,a story of failure

The Bologna Process is a unique harmonisation process taking place outside the policy-making framework of the European Union. It aims at enhancing the comparability and compatibility of higher education structures and degrees across Europe, as well as to institutionalise quality assurance mechanisms. The aim of this article is to provide a condensed, up-to-date overview of the Bologna Process with regard to structural characteristics, before embedding it into a discussion on processes on voluntary policy convergence and to which extent we should be able to find this kind of policy harmonisation in the realm of the Bologna Process. Related to this are questions why this, in principle, completely voluntary process of policy harmonisation, has appealed to so many countries and why they might or might not feel committed to the implementation of its policies and tools.     

The Conversation of Scholarship

Abstract

At its core, scholarship is a long, threaded, multiparticipant conversation. Scholars, students, librarians, and publishers all are engaged. There are side conversations addressing specific fields and larger conversations asking probing questions about the nature of scholarship as a whole. Librarians’ contributions to the broader conversation have not always accounted for our side conversations, among ourselves or with other participants. Our choices in acquisitions, our choices in services, even our choices in library job titles and responsibilities signal and shape the scholarly conversation in ways that are often opaque. It is imperative that we openly acknowledge the influence and impact of our side conversations to ensure our full participation in the conversation of scholarship.

Alike but different: the understanding of rituals among Sri Lankan Tamil Hindus in Denmark

ABSTRACT

This article will discuss the meaning(s) of rituals among Sri Lankan Tamil Hindus in Denmark with special focus on the second generation. It will use Roy A. Rappaport's theory on ritual both as communication and as a basic social act, but it will also, in line with Jan Assmann and Hervieu Legér, understand the ritual as a storing place of collective memory. It will give a short outline of what can be called the institutionalisation but also the placemaking of the Sri Lankan Tamil Hindu tradition in Denmark, but the empirical focus will be on the chariot procession (Tēr), which attracts thousands of participants every year. The Tēr procession is an example of continuity and change. Continuity because the participants try to reproduce the ritual as they know it from Sri Lanka, however, changed so it fits into or communicates with the new setting.     

跨文化情景下的文化认同与和谐相处——以在美国阿肯色大学的学习生活经历为例

以美国阿肯色大学跨文化交流的经历为背景,以具体文化情景下的不同感受和体验为基础,揭示了在跨文化交流的情景下文化认同的两种表现:既表现为因语言相同或相近、宗教信仰相同、地域相近或相邻而产生的亲近感和归属感;也表现为因文化差异而产生的吸引或冲突。而在这种跨文化交流的情景下要实现和谐相处,就要做到"我"与"他者"之间文化上的"欣赏"与"分享",即"文化的互为主体性",而这种和谐的实现源于人类本性的相通,即"人类心灵的共同点"。     

数字营销传播背景下的新型社会形态研究

随着数字营销传播的发展,社会形态发生了巨大的改变.数字营销传播的载体改变了传统的生活方式,让消费和传播变得更加精准,各种各样私人化的定制服务满足了人们个性化的需求.这种新型的营销传播方式让消费者在市场中占据了主导位置.数字技术在改变生活方式的同时,也改变着人们的认知系统和价值观念.经过数字营销传播的洗礼,社会结构重新部落化,沟通变得更加平等.行业之间开始融合,不同领域的行业边界变得模糊不清.以往的营销传播理念已无法满足当今大变革时代的需求,新型社会形态需要全新的营销传播理论与之相对应.     

媒介演化与社会性格的变迁——基于大卫·理斯曼社会性格理论的媒介学解释

媒介与社会性格形塑之间存在着密切的对应性关系,社会学家大卫·理斯曼在其著作《孤独的人群》中探讨了历史文化变迁中社会性格所存在的深刻复杂性,其中就已经涉及到了媒介变迁与社会性格转化之间的关系问题。本文尝试在理斯曼的研究基础上,结合新近发展出的媒介研究理论,将媒介技术特性与社会性格转化之间的关系加以主题化,使之成为一个具有相对独立性的学术问题,并试图对理斯曼提出的所谓“传统导向性格”、“他人导向性格”与“内在导向性格”等社会性格的媒介形塑原因作出解释。     

3D打印中CAD文件的定性与复制问题研究

3D打印技术的发展使著作权法上的复制变得更为高效便捷,由此产生了一系列亟待梳理和解决的问题。基于3D打印技术原理,可将其分为输入和输出两个环节。在输入环节,对CAD文件的作品类型进行规制,采用视觉标准界定立体作品,并以“美术作品+模型作品”的思路进行综合保护;在输出环节,3D打印属于复制,且可以实现从平面到立体和从立体到立体的复制形态,复制权的控制范围应不限于现行法律所列举的方式。针对3D打印技术在网络传播中的侵权风险,应对合理使用中的私人复制予以限制,灵活运用“三步检验标准”对合理性进行审查。3D打印在著作权法方面并未引发新的法律问题,现行制度已存在包容空间,不必为其特设著作权新规,通过对现有规则的解释和借助已有案例的适用经验便能解决可预见的著作权法争端。
