The Satchel system architecture: Mobile access to documents and services

Mobile professionals require access to documents and documentrelated services, such as printing, wherever they may be. They may also wish to give documents to colleagues electronically, as easily as with paper, facetoface, and with similar security characteristics. The Satchel system provides such capabilities in the form of a mobile browser, implemented on a device that professional people would be likely to carry anyway, such as a pager or mobile phone. Printing may be performed on any Satchelenabled printer, or any fax machine. Scanning, too, may be accomplished at any Satchelenabled scanner. Access rights to individual documents may be safely distributed, without regard to document formats. Access to document services is greatly simplified by the use of context sensitivity. The system has been extensively tested and evaluated. This paper describes the architecture of the Satchel system.     

Response Selection Difficulty and Asymmetrical Costs of Switching Between Tasks and Stimuli: No Evidence for an Exogenous Component of Task-Set Reconfiguration.

Four task-switching experiments examined the notion of an exogenous component of task-set reconfiguration (i.e., a process needed to shift task set that is not initiated in the absence of a task-associated figuration stimulus). The authors varied the complexity and familiarity of stimulus-response (SR) mapping rules to produce differentially time-consuming reconfiguration demands. Tasks with more complex or less familiar rules did not display increased switch costs, given that stimulus repetitions were excluded from the analysis. These results do not support the idea of exogenous reconfiguration. Moreover, stimulus repetitions inflated task-switch costs and did so disproportionately for tasks with increased response selection difficulty, thereby demonstrating that insufficient control of the sequence of stimuli may yield results that mimic those predicted by exogenous reconfiguration accounts.

Carmi Harari (1920-2003).

Obituary for psychologist Carmi Harari (1920-2003). Among other things the obituary notes that, Harari was a noted psychoanalyst, clinical and forensic psychologist, disability examiner, and prolific workshop leader worldwide on issues of peacemaking and political psychology. He was an active officer and member of many international psychology groups, including the Psychologists for Social Responsibility, the National Register of Health Service Providers in Psychology, the National Accreditation Association for Psychoanalysis, the Council of Representatives of the APA (1974-1994), and the Committee on International Relations in Psychology. He served as president of the International Association of Applied Psychology, president of the New York State Psychological Association, and president of the Rockland County Psychological Society. Harari was an APA fellow in eight divisions, including Clinical, Psychotherapy, and Independent Practice. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

电磁干扰滤波的半导体解决方案

如今,人们不仅希望电子产品小巧、美观,还需要它们在任何环境下都能可靠工作,而且不会干扰其它电子装置。为了达到这样的目标,产品产生或辐射的电磁干扰(EMI)必须得到控制,同时它们也必须能耐受干扰环境。我们以一只通过线缆与膝上电脑或耳机相连的手机为例进行分析,电缆的天线作用会接收周围RF噪声,并将其引入手机中。要防止这一现象,可以在紧靠手机连接器的位置接入一个EMI滤波器,同时彩色LCD显示器的数据总线、通用串行接口(USB)端图1 采用CSP封装、带有接地散热片或分立器件的滤波器频率响应特性对比口等部位也需要EMI滤波器,固…     

Some heuristics for the consensus ranking problem

In this paper, we propose a consensus ranking function and several heuristics to solve the consensus ranking problem. Empirical testing results of the solution strategies are presented to indicate their solution efficiency.     

跨越鸿沟,游刃有余-LabVIEW 7 Express兼具易用性和强大的编程功能

LabVIEW 7 Express是300多位工程师花费数年、进行了数百次可行性研究的跨领域工程的结晶。其重要创新——如无需编程的互动式测量与分析工具,增强的开发对象库,以及更多直观的图形化开发工具——使您能更方便地使用且拥有更强大的功能。以往的编程工具中,基于配置的工具便于使用,但其适应性、可测量性和功能都有不足,而传统的编程工具虽然功能强大且易于开发应用程序,但需要投入大量的时间和金钱;LabVIEW则通过Express VI、测量I/O助手和增强的配置对象,解决了以往编程工具中存在的鸿沟,为更多的用户—无论入门者还是专家——提高了…     

A network for digital data services

British Telecom is planning the introduction of an integrated services digital network, designed to carry data, text and voice. The Kilostream services will provide a dedicated data network that will support synchronous data transmission at datarates from 2 400 bit/s to 48 kbit/s, using both X.21 and X.21bis customer interfaces. The paper examines the planning of the system, equipment realization and the network applications being considered. Future developments of the Kilostream concept are also discussed.     

Suicide Intent and Accurate Expectations of Lethality: Predictors of Medical Lethality of Suicide Attempts.

The degree of intent to commit suicide and the severity of self-injury were examined in individuals (N = 180) who had recently attempted suicide. Although a minimal association was found between the degree of suicide intent and the degree of lethality of the attempt, the accuracy of expectations about the likelihood of dying was found to moderate the relationship between suicide intent and lethality. Specifically, higher levels of suicide intent were associated with more lethal attempts but only for those individuals who had more accurate expectations about the likelihood of dying from their attempts.
