Participation, Remediation, Bricolage: Considering Principal Components of a Digital Culture

Within media theory the worldwide shift from a 19th-century print culture via a 20th-century electronic culture to a 21st-century digital culture is well documented. In this essay the emergence of a digital culture as amplified and accelerated by the popularity of networked computers, multiple-user software, and Internet is investigated in terms of its principal components. A digital culture as an underdetermined praxis is conceptualized as consisting of participation, remediation, and bricolage. Using the literature on presumably “typical” Internet phenomena such as the worldwide proliferation of independent media centers (indymedia) linked with (radical) online journalism practices and the popularity of (individual and group) weblogging, the various meanings and implications of this particular understanding of digital culture are explored. In the context of this essay, digital culture can be seen as an emerging set of values, practices, and expectations regarding the way people (should) act and interact within the contemporary network society. This digital culture has emergent properties with roots in both online and offline phenomena, with links to trends and developments predating the World Wide Web, yet having an immediate impact and particularly changing the ways in which we use and give meaning to living in an increasingly interconnected, always on(line) environment.     

屠格涅夫创作中的“激情”人物

在屠格涅夫的创作中,有两组人物形象:爱情故事中的"茨冈女人"与社会运动中的"激进分子",在内在精神上,他们都蕴藏着某种"激情"与"狂热"。屠格涅夫对这类"激情"人物的态度是"既怕又迷";而这种双重态度,又折射出屠格涅夫爱情观与政治观的一致性。     

浅谈《说文解字》中的“儿”部字

“儿”是《说文解字》五百四十个部首之一,统属着两个汉字,但许慎对其解释存在着一些问题。文章从古文字学的角度,以“儿”与“殳”之间的语音、字形联系为出发点,全面考察其能否构成部首、作为“殳”构件时的字形演变及许慎将其作为部首的原因。分析了许慎认为从“儿”部的字“儿”和“鳧”的构成及其归部问题。

Naphthalene decomposition in a DC corona radical shower discharge

The naphthalene decomposition in a corona radical shower discharge (CRS) was investigated, with attention paid to the influences of voltage and initial naphthalene density. The OH emission spectra were investigated so as to know the naphthalene decomposing process. The by-products were analyzed and a decomposing theory in discharge was proposed. The results showed that higher voltage and relative humidity were effective on decomposition. The initial concentration affected the decomposing efficiency of naphthalene. When the initial naphthalene density was 17 mg/m³, the decomposition rate was found to be 70% under 14 kV. The main by-products were carbon dioxide and water. However, a small amount of carbonic oxide, 1,2-ethanediol and acetaldehyde were found due to the incomplete oxidization.     

“学衡派”研究综述

“学衡派”研究的兴起与化界追溯自身的“人传统”的迫切愿望紧密相连。作为“新人主义”代表的“学衡派”在中国学化史上确实占有一席之地。但仔细探求其来龙去脉却发现中国并没有一个完整的、曾经确定存在的“人传统”可言。“人主义”更多地被用于指涉传统道德等因素。
