称呼语选择的顺应性理论探讨

称呼语在人们的日常交往中起着非常重要的作用,它常是传递给对方的第一个信息。发话者可以通过称呼语的选择来引起受话者注意和保持与受话者之间的联系,对于日常交际和人际关系有着重要的影响。得体地使用称呼语是交际能力中很重要的一个方面。因此,对称呼语的研究具有重要的实践意义。文章尝试以Verschueren(1999)的语言顺应论为理论框架来阐释称呼语的正确选用,以期对此语言现象的进一步研究有所贡献。

基于普适计算的虚拟场景自适应网络发布研究

针对移动设备访问三维虚拟场景受到网络带宽和终端计算能力的制约,使得在线利用虚拟现实进行移动学习效率不高,基于此提出了基于普适计算的自适应优化选择技术.对三维实体进行本体语义描述,建立相应的优化模型.在此基础上通过WURFL对手持移动设备进行采样获取设备参数,对参数进行分析从而建立普适规则,利用普适计算进行自适应优化选择.测试结果表明,经过自适应选择后手持移动设备荻取三维虚拟场景资源的速度和效率得到明显提高.     

基于DSP的光栅分度盘及其光栅信号精细分

对提高光栅的细分准确度进行了研究,提出了一种正切与余切相结合的方法.针对实际光栅信号的不稳定性,利用光栅发讯头输出正切、余切信号峰峰值与直流电平的漂移,自动修正反正切与反余切的查找表格.该方法应用于精密倾光学分读盘测量系统,使细分误差仅与光栅信号第一个采样值和最后一个采样值的精度有关,与测量过程中的光栅信号采样值的误差无关,同时采用DSP处理采样数据,速度更快,并成功应用于光栅分读盘系统,精度为2″.     

Social desirability and the randomized response technique.

The randomized response technique (RRT) is designed to increase respondents' willingness to answer truthfully questions of a sensitive or socially undesirable nature. This study tested the hypothesis that the difference between the proportion of "yes" responses obtained under self-administered direct questioning and the proportion of "yes" responses obtained under an RRT procedure would be related to the social desirability of a "yes" response to the question. The hypothesis was confirmed by data from 404 undergraduates; the RRT may provide more valid responses to items of a socially desirable and undesirable nature. The RRT deserves more attention because it can circumvent biases due to untruthful responding, demand characteristics, and evaluation apprehension as well as assure the confidentiality of the data.

Social recovery of monkeys isolated for the first year of life: I. Rehabilitation and therapy.

Previous research demonstrated that 12 mo of total social isolation initiated at birth produced severe and seemingly permanent social deficits in rhesus monkeys. Such monkeys exhibited self-clasping, self-mouthing, and other stereotypic, self-directed responses. Recent research has indicated that 6-mo-isolated monkeys could develop social behaviors if exposed to younger, socially unsophisticated "therapist" monkeys. In the present experiment, 4 12-mo isolate-reared monkeys developed appropriate species-typical behavior through the use of adaptation, self-pacing of visual input, and exposure to 4 younger "therapist" monkeys. Adaptation enabled the isolate Ss to become familiar with their postisolation environment, while self-pacing facilitated their watching the therapist Ss' social interactions. The isolates showed a marked decrease in self-directed behaviors following extensive intimate contact with the therapists. Species-typical behaviors significantly increased during this period, so that the isolate behavioral repertoire did not differ substantially from the therapist behavioral repertoire by the end of the therapy period. Results clearly fail to support a critical period for socialization in the rhesus monkey, and an alternative environment-specific learning hypothesis is proposed.
