赛博民族志下虚拟集体记忆的构建与生活空间文化的生产——以微信构建的“微文化”为例

随着自媒体时代蓬勃发展,多元化的集体记忆以及空间文化正在被无节制、无边界的塑造,正基于此,网络式的赛博空间为现代人类提供了一个与时代契机的舞台。本文试着运用人类学的视角,以微信形成“微文化”圈为例子,同时结合对赛博文化的探讨与分析路径,来阐释在虚拟网络空间中人们是如何来构建回到现实中会被社会化的集体记忆,探析网络信息碎片化的特点下,生活空间文化生产如何与形成的虚拟整体性互动,这种互动性是怎么从网络空间中转移到现实具体的生活文化圈中。

自我概念对两类怀旧广告诉求有效性的影响

在怀旧风潮盛行的大背景下,怀旧广告日益受到了广告主的青睐。然而,由于怀旧诉求未能正确匹配目标受众,导致一些怀旧广告的无效甚至是起反面效果。基于此,通过区分个人怀旧诉求和虚拟集体怀旧诉求,并将其联结于消费者的两种自我概念形态(独立自我与互依自我),经由两个实验探查了受众的自我概念形态对不同怀旧广告诉求的反应。实验一采用2(怀旧诉求:个人怀旧与虚拟集体怀旧)×2(自我概念:独立自我与互依自我)组间因子设计,检验自我概念形态是否对个人怀旧诉求广告、虚拟集体怀旧诉求广告的效果起调节作用;实验二通过对自我概念采用不一样的操控方式,对认知反应进行更加有效的测量,对同一被试接触到怀旧广告信息前后的品牌态度进行对比等,重复检验了实验一的研究结果。实验结果显示:独立自我程度高的消费者往往偏好于个人怀旧诉求,而互依自我程度高的消费者往往偏好于虚拟集体怀旧诉求。研究结果表明:怀旧虽是一项很好的广告题材,但在具体应用时,需要注意怀旧诉求与目标受众的匹配性。本研究拓展了自我概念这一重要心理变量在怀旧广告领域的应用;同时,论文研究结果对于怀旧营销、跨文化营销也有一定的启示意义。

网络化的远程教育班级管理平台的设计

远程教育中,很多学生由于缺少交流产生孤独感,从而导致辍学。网络化班级管理系统主要是为远程教育学生提供感情归属的目的而设计的。系统分前台和后台两部分,前台为学生提供温馨的网上班级环境和协同学习环境,并提供人性化的管理和服务功能;后台为班主任提供班级事务管理平台,使班主任工作从手工化转向信息化、自动化。

基于WEB平台的高校班级网站的设计与实现

大学时代的同学之情真挚异常,但大学环境不同于初、高中,班级活动匮乏,日常习惯昼伏夜出,使得同学之间的接触越来越少,交流难度也趋于增大。尽管有QQ,微信,但这些方式趋于娱乐化。因此,一个全新正式的交流渠道是必要的。结合大学情况,开发设计了一个校园班级网站,旨在学生可以更加正式的交流。网站具备基于班级进行交流的功能,可以把大家集中起来,进行班级事务的交流和信息的传达,极大简化了信息传播的流程,增强班级凝聚力。记录大学生活的点滴,为班级资源的积累提供了新的方式和空间。

中小学多功能测训与实验平台的开发

近年来计算机已然成为教与学不可或缺的工具，然而借助计算机的学习目前还存在诸多问题，尤其是缺少与中小学对接的实验平台。实验学校及其他的教育研究工作者急需简便易行的多功能测训与实验平台。

Empirical Analysis on Influence Mechanism of Cohesiveness and Collective Efficacy of Virtual Community Based on Triadic Reciprocal Determinism

The virtual community has become a new life style as for human,but the public's acceptance is relatively low at present.So the research about the mechanism of the influence on the cohesiveness and the collective efficiency in virtual community has an important theoretical value and practical value.In the paper,the key variables that affect virtual community cohesiveness are extracted from two aspects—self-perception of community members and community environment,and the influence mechanism model of virtual community cohesiveness and community collective efficiency is established based on Triadic Reciprocal Determinism.By means of the questionnaire on the community members and the empirical analysis,the key factors influencing cohesiveness of virtual community are brought up,as well as the mechanism that the four dimensions of cohesiveness work,on collective efficiency.According to the results,it is practically meaningful that the problems and insufficiency in the operation of existing virtual community are discovered,which guides the operating managers of the virtual community to formulate operation policy of the virtual community for operating managers to develop strategies.

Parameter Identification of Rubber Isolators Using Frequency-Dependent Spring and Damper Coefficients

A model to describe the hysteresis damper character of rubber material is presented in this paper. It consists of a parallel spring and damper, whose coefficients change with vibration frequencies. In order to acquire these relations, the force decomposition is carried out according to some sine vibration measurement data about nonlinear forces changing with deformations of the rubber material. The nonlinear force is decomposed into a spring force and a damper force, which are represented by a frcquency-dependent spring and damper coefficient, respectively. Repeating this step for different measurements will give different coefficients corresponding to different frequencies. Then, application of a parameter identification method will provide the requested functions over frequency. Using those formulae, as an example, the dynamic character of a hollow shaft system supported by rubber rings is analyzed and the acceleration response curve in the centroid position is calculated. Comparisons with sine vibration experiments of the real system show a maximal inaccuracy of 8. 8 %. Application of this model and procedure can simplify the modeling and analysis of mechanical systems including rubber materials.

Precise perception of virtual object position in real world

There is a deviation between actual and theoretical perceived positions of virtual object in stereoscop-ic display.Therefore,methods for precise position perception in real world are proposed in this paper.The causes for the deviation are analyzed on the basis of geometrical optics .Then deviation correctionsare performed by error compensation with mathematic method and by remodeling virtual viewpoint dynami-cally with the movement of physical viewpoint.Experimental results show that these methods can reducethe position deviation to less than 10 millimeter,meeting the requirements for direct manipulation in mul-ti-sensory virtual environment.
