拟态狂欢:消费时代电视体育传播的范式

以"拟态环境"和"狂欢"视角提出和分析了"拟态狂欢"概念的内涵,解析了当下电视体育传播的机理及具体措施。研究认为:电视体育是基于现代生活与商业利益的被动型拟态狂欢;电视体育所遵循的传播理念是快乐原则;电视体育奇观化的音像表达的目的是感官刺激;为了拟态狂欢效果,电视体育制作流程并不轻松。最后在符号学和批判学派理论的观照下对电视体育传播的这一范式进行了反思。

Launching the Virtual Academic Center: Issues and Challenges in Innovation

In October 2010, the University of Southern California School of Social Work entered the online education environment with the launch of the first national web-based MSW program. After an initial enrollment of 80 students, in just 3 years this state-of-the-art MSW, offered in a technology-advanced synchronous and asynchronous format, has generated an enrollment of 2,000 students residing in 38 states. The development and rapid growth of the Virtual Academic Center has not been without significant challenges, the most substantial of which has been the creation of a national field education program. This paper describes the MSW courses taught in the online environment, and pedagogical hurdles faced in order to maintain the educational quality that is the hallmark of the School's campus-based MSW program.

基于Web的虚拟地景信息系统研究

基于Web的虚拟地景信息系统是对如何将3DGIS、WebGIS以及VRGIS有效结合起来的一次探索。该系统提供基于Web运行的三维可进人地图,用户通过网页浏览器即可在计算机实时生成的虚拟地景中随意漫游和与之交互。系统基于Java3D实现,在分析Java3D场景图数据结构的基础上,创造性地提出将场景数据保存到数据库中,场景对象按要素分类建表,并把场景对象的属性数据和空间数据保存到同一记录中,从而实现客户端对场景要素的显示控制和对场景对象属性信息的查询。     

Cultural differences in the perception of critical interaction behaviors in global virtual teams

We investigated whether members of virtual teams from the U.S., India, and Belgium perceived the same interaction behaviors to be critical for team functioning as Dutch members from an earlier study. Thirteen virtual team workers from the U.S., 11 from India, and 11 from Belgium were interviewed by means of the Critical Incident Technique Flanagan [Flanagan, J. C. (1954). The critical incident technique. Psychological Bulletin, 51, 327–358]. The total number of critical incidents from all countries was 493 and most incidents could be grouped into the same 13 categories as those found in the original Dutch study. However, the results showed that the distributions of the critical incidents from the American, Indian, and Belgian respondents differed from those of the Dutch. Indian and Belgian respondents also mentioned a new category of critical incidents: Respectfulness. The cultural differences were interpreted by means of Hofstede's [Hofstede, G. (2001). Cultures consequences: comparing values, behaviors, institutions, and organizations across nations (2nd ed.). Thousand Oaks, California, U.S.: SAGE Publications] dimensions.

虚拟现实中建筑建模的研究与实现

建筑是虚拟三维数字校园模型中的基本对象,已有的对建筑的表示局限于某一层次级别,连续层次级别这一概念对地理信息系统中的建筑进行表示和建模,而连续层次级别方法统一了虚拟三维数字校园模型中不同类型的建筑的表示。     

基于背景差分法的虚拟手术损伤区入刀点定位

在虚拟手术系统模型中,特别是脑外科手术中,由于背景图像色彩的非规则性和非均匀性,导致对脑部损伤区域的手术入刀切割点的定位不准,影响手术精度和效果。传统方法采用损伤区域差异特征信息提取方法实现入刀点定位,对脑部特征二维灰度图片缺陷边界的定位效果不佳。提出一种基于背景差分法的虚拟手术损伤区入刀点定位算法,构建了虚拟手术的总体结构模型,将背景图像和人体软组织目标图像划分为多个子块,基于直方图选择阈值对差分图像序列进行二值化,得到高斯虚拟人体器官解析模型。设计医学图像分割算法,采用背景差分技术确定手术器械与软组织发生碰撞的激励因子,快速获取碰撞点,实现对虚拟手术入刀点的准确定位。实验结果表明,采用该算法实现虚拟手术系统设计和图像重构,对手术过程中器官损伤区域切割入刀点定位准确,性能优越,视景效果较好,计算时间缩短,精度提高。
