Nicholas Hobbs (1915–1983).

Presents an obituary for Nicholas Hobbs. Just at the end of his stellar career of public service through psychology, Nick Hobbs received very appropriate honors showing that psychologists and many others knew what a precious national resource his life had been. Only days before his death from cancer on January 23, 1983, he participated in the dedication of the Nicholas Hobbs Laboratory of Human Development of the Peabody College for Teachers of Vanderbilt University, part of the Kennedy Center for Research on Education and Human Development that he founded and directed at its beginning. Two years earlier, he had received two parallel American Psychological Association (APA) awards--one for Distinguished Contributions to Psychology in the Public Interest and another for Distinguished Professional Contributions "utilizing psychological knowledge in the public interest and social policy." As the citations and testimonials on these occasions variously noted, Nick gave creative, responsible, and effective service to the institutions that he helped administer, to the Southern region from which he sprang, to the APA, and to the profession of psychology, but above all to the nation's children and youth, especially those who grew up with disadvantage and difficulty.

全球移动增值业务发展现状

移动增值业务在全球的发展速度依然很快,非话音收入占电信总收入的比重越来越大.在移动增值业务的发展上,日本遥遥领先,韩国紧随其后.在中国,虽然短信业务收入开始下降,但无线应用协议(WAP)、交互式语音回应(lVR)等业务收入快速攀升,从而保证了移动增值业务在中国的发展速度.由于中国信息产业部整顿收费混乱的移动增值业务市场,使服务提供商/内容提供商(SP/CP)的暴利时代成为过去,增值业务市场进入精耕细作期.随着用户对移动增值业务新的需求的不断增长,整首音乐下载、移动E-mail以及手机电视等业务将成为未来全球最有前途的移动增值业务.

A review on queueing network models with finite capacity queues for software architectures performance prediction

A review is carried out on how queueing network models with blocking have been applied so far into the performance evaluation and prediction of Software Architectures (SA). Queueing network models with finite capacity queues and blocking have recently been introduced and applied as more realistic models of systems with finite capacity resources and population constraints. Queueing network models have been often adopted as models for the evaluation of software performance. Starting from our own experience, we observe the need of a more accurate definition of the performance models of SA to capture some features of the communication systems. We consider queueing networks with finite capacity and blocking after service (BAS) to represent some synchronization constraints that cannot be easily modeled with queueing network models with infinite capacity queues. We investigate the use of queueing networks with blocking as performance models of SA with concurrent components and synchronous communication. Queueing theoretic analysis is used to solve the queueing network model and study the synchronous communication and performance of concurrent software components. Our experience is supported by other approaches that also propose the use of queueing networks with blocking. Directions for future research work in the field are included.     

基于Parlay X的下一代电信增值业务模型研究

Parlay X是一套简单易懂、比之Parlay在更高层次抽象电信网络基本功能的应用编程接口(API),它以Web Service的形式供IT应用开发者在开发的应用中调用电信网络功能.下一代网络业务的发展是一个渐进过程,对运营商来说,如何以更小的成本快速开发和部署新业务成了当务之急.文中介绍了Parlay X体系结构模型,着重提出了基于Parlay X的电信增值业务过渡模型,并对短信业务的开发流程进行了分析.
