Online Synchronous Audio and Video Environments for Education,Training, and Human Service Delivery: A Review of Three Products

ABSTRACT

This application review describes the Internet Video Virtual Classroom (IVVC). The IVVC is a synchronous online environment where instructors can deliver course curriculum to students in real time and at a distance. Features of the IVVC that are described include video, audio, and text communication between participants, information sharing, facilitating participation, promoting group work, and documenting interactions. In addition, problems and limitations that can exist in the IVVC are discussed. Finally, to further illustrate the IVVC, three specific products (Adobe Acrobat Connect Professional, Elluminate, and Flashmeeting) are described.     

《诗小序》与诗歌“美刺”评价体系的确立

《毛诗小序》是《诗经》学史上的一座里程碑,它形成于战国孟子一派学者之手。《诗序》对后世最大的影响,是将诗政治化、历史化,并由此而建立起以"美刺"为核心的评价体系。其意义指向在于国家典礼、时世变迁、政治兴衰以及社会风习等方面。在诗的政治目的性意义指向的表述中,《诗序》实际汇集了诗人之意、典礼用诗之意、诗乐之意、采诗或编诗者之意等四方面的意思。故而引起了后人的种种误解。     

“过渡时代”的文学镜像——论早期《小说月报》(1910—1920)刊载的社会小说

1910—1920年的《小说月报》因曾经是鸳鸯蝴蝶派的阵地而被否定。实际上,恽铁樵接任主编后就进行改革,登载了大量有价值的社会小说,其社会小说对政治思潮与社会变迁的反映、对婚姻自由与男女平权理念的张扬、对侨民问题与工人生存状态的关注等,均引人注目。从语言层面看,其早期白话小说语言尝试也为五四新文学的发展提供了借鉴。

“兄弟作坊”与“夫妻档”：《小说月报》翻译行为解读

上个世纪20年代,鲁迅、沈雁冰、耿济之兄弟及郑振铎夫妇,开创了《小说月报》“兄弟作坊”与“夫妻档”的翻译模式。这种特有的家族式翻译行为所带来的西洋名家小说、世界文学潮流,孕育了中国新文学的萌芽,也使得《小说月报》迅速成为新文化运动中最有影响的刊物之一,对翻译文学的发展做出了特有的贡献。     

Mobile phones and core network growth in Kenya: Strengthening weak ties

In contrast to recent US studies showing a decrease in core network size, our Kenyan data reveals substantial network growth. We attribute this to the diffusion of mobile telephones. Results from pooled survey data from Nairobi professionals and entrepreneurs in 2002 and 2007 as well as qualitative interviews from 2007 to 2009 show virtual saturation in the diffusion of phones during this period, but no direct effect of technology use. What explains this puzzle is a network effect of mobile telephony: increased technological access to existing networks in a context of resource scarcity leads to a strengthening of weak ties and the enhancement of core networks among Kenyans. Video ethnographic data before and after the 2007 post-election unrest supports this interpretation, showing that mobile phones are a crucial resource in managing interpersonal networks for instrumental purposes.     

Eyes on the Block: Measuring Urban Physical Disorder Through In-Person Observation

In this paper, we present results from measuring physical disorder in Los Angeles neighborhoods. Disorder measures came from structured observations conducted by trained field interviewers. We examine inter-rater reliability of disorder measures in depth. We assess the effects of observation conditions on the reliability of reporting. Finally, we examine the relationships between disorder, other indicators of neighborhood status, and selected individual outcomes.Our results indicate that there is considerable variation in the level of agreement among independent observations across items, although overall agreement is moderate to high. Durable indicators of disorder provide the most reliable measures of neighborhood conditions. Circumstances of observation have statistically significant effects on the observers’ perceived level of disorder. Physical disorder is significantly related to other indicators of neighborhood status, and to children’s reading and behavior development.This result suggests a need for further research into the effects of neighborhood disorder on children.

Representing sex workers in video games: feminisms,fantasies of exceptionalism,and the value of erotic labor

This article critiques the representation of sex workers in “AAA” video games, with a focus on the devaluing of erotic labor. Existing feminist commentary has interpreted these representations as examples of the objectification of female game characters, perpetuating harmful misconceptions of sex work as fundamentally exploitative. By contrast, taking cues from feminist media studies, porn studies, and sex workers rights activism, I argue that what makes these representations of sex workers problematic is not their engagement in erotic labor but the ways that the games in which they appear devalue that labor, through both dialogue and interactive elements. Across their many appearances in AAA games, it is strikingly common for sex workers to offer their services to player-characters for free or at a discount, or for games to allow players to take their money back after erotic labor has been performed. This contributes to a gendered fantasy of exceptionalism in which a player-character’s masculinity is tied to being too attractive or too powerful to pay for sex. Critiquing these representations demonstrates how AAA video games prompt players to reenact widespread cultural biases against sex work. It also points toward the need for a diversity of feminisms within game studies.
