关于Gelfer函数

我们称单位圆盘中的解析函数f(z)=1+(sum from n=1 to ∞)a_nZ~n为Gelfer函数,如果对一切Z,∈△,都有f(z)+f(C)≠0。文〔1〕中关于Gelfer函数提出了若干问题,我们解决了其中的两个。

Growth,development and performance of the Philippine and Brazilian telecommunications sectors: A contextual analysis

The direct determinants of an industrial sector's success is usually taken to be ownership, market structure, and the regulatory structure in place. However, Mody (1987) has noted that frequently the performance of communication technology has more to do with economic, political and cultural contextual factors than with technical efficiencies. In the light of this observation, this comparitive case study seeks to assess the importance of the contextual forces that have influenced the development of the telecommunication sectors in the Philippines and Brazil.     

Notes on Contributors

The study reported herein aimed to identify and discuss the nature and pattern of the uses of new media through a notable YouTube phenomenon. It analyzed 132 online videos centered on ‘Bus Uncle,’ a YouTube celebrity who rose into fame in Hong Kong during April 2006. Most of the videos drew references from local popular culture texts. They were mostly playful and sarcastic in their undertones. The collective behaviors in YouTube suggest that this hugely popular video-sharing site takes on the roles as public space, a playground and a cultural public sphere.

A Place to Protest

The national media converged on Baltimore, Charleston, and Ferguson, Missouri, in 2014 and 2015 to cover protests in response to police violence toward African American males. Although national and local media covered the events and the aftermath, alternative media sought to provide additional viewpoints and spur readers to respond. This study analyzed the practices, content, and public discourse connected to alternative weekly newspapers in Baltimore, Charleston, and St. Louis. The study examined whether the publications reflected ideal roles of alternative media, including representing different viewpoints, using non-traditional methods of content, and providing a space for the public to challenge systems of power and oppression. The authors also studied the online forums associated with all three publications, including each organization’s website and Facebook page, as potential spaces for alternative publics to emerge around a shared interest in collective action. The publications showed some characteristics of the ideal form of alternative media, but most lacked the diverse voices and critical calls to action needed to represent the normative standard. The discourse the news organizations spurred also fell short of the ideal. The forums lacked rational and critical engagement, and commenters largely failed to promote sincere attempts to engage in community conversation.

公权对私域的蔑视与僭越:对“有偿家教”及其行政处理方式的若干思考

“有偿家教”现象的存在并不完全是教育本身“问题”所致,“家教”之所以受欢迎,是因为它能够因材施教提供比较优质的教育。教师在日常工作之外从事“有偿”服务是无可厚非的,需理性看待“有偿家教”的现象。处理“有偿家教”问题的方式,不能无条件侵犯公民的私生活领域,需理性实施对“有偿家教”的管理。
