工作压力对职场网络偏差行为的影响：工作意义的调节效应

本文以447名员工为对象,采用问卷法研究了工作压力对职场网络偏差行为的影响,并考察了工作意义对上述影响的调节作用。结果表明：角色模糊对网络娱乐和商务交易具有显著的正向预测作用;角色冲突对网络娱乐正向影响显著;角色超载则能显著正向预测网络攻击;职业发展则对网络沟通和网络攻击的正向预测作用都显著。研究还发现,高水平的“使命”定位,不仅减弱了角色模糊对网络娱乐和商务交易的影响,而且减弱了角色超载对网络攻击的影响。     

基才AMESim的矿用汽车行驶动力学仿真研究

将AMESim仿真软件应用于矿用汽车行驶动力学仿真研究,利用AMESim软件的平面机构库建立了行驶系统的四自由度动态仿真模型,对该系统在台阶路面上的动力学响应进行了动态仿真,研究了轴距中心处及车身俯仰角的动态变化情况,为矿用汽车悬架系统的设计提供了依据。     

基于LabVIEW的货车复合材料超载预检系统设计

超载超限运输严重损害公路,影响公共安全。为了有效制止超载行为,设计了一种复合材料称重系统。系统利用LabVIEW软件和数据采集卡、传感器,在复合材料称重结构支持下,快速识别车牌号,能测量复合材料称重结构加载后的应力及变形,进而计算出货车的载重量,对于超载货车,系统即时发出超载警示。     

Reducing Patron Information Overload in Academic Libraries

Information overload interferes with our abilities to use information effectively. It represents a challenge in searching print as well as online collections. Academic librarians have developed strategies to help their patrons reduce the effects of information overload. This article provides best practices employed by academic librarians to reduce their users’ information overload. Five themes emerged in a review of the literature: information presentation, library instruction, user strategies, librarian roles, and software technologies. Information literacy instruction remains particularly important in combating information overload since the promotion of users’ research skills facilitates their search competencies. Research on information problem solving that focuses on metacognitive strategies may help decrease information overload among users searching digital libraries.
