The social construction of the personal past and its implications for adult development.

This article examines conversational recounting about experiences as a potential mechanism by which people socially construct themselves and their worlds over the life span and the resulting implications for understanding adult development. Two principles governing conversational recounting of past events are proposed: coconstruction (the joint influences of speakers and contexts on conversational reconstructions of past events) and consistency (the influence of a conversational reconstruction on subsequent memory). Operating together, the principles provide an account for how autobiographical memory is socially constructed. In addition, the principles may illuminate how conversations about the past can influence the development of identity in adulthood. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

CDMA800与多系统基站共址的干扰保护研究

目前电信业已完成重组和3G牌照的颁发,进入全业务竞争时代,应推动网络节约、高效、环保地运营,然而重组后的3大运营商共拥有6张网络,重复性建设与资源浪费问题日趋严重。为探讨电信运营商共建共享中的技术问题,本文研究了CDMA800与多系统基站共址所需要的干扰保护隔离度,并根据广泛使用的天线型号,研究实际的干扰保护距离及工程实施可行性的措施。

Steps Across the Border – Cooperation, Knowledge Production and Systems Design

The computer support of cooperation andknowledge production across sociallydistributed activity systems has become animportant topic in the context of the discourseon ``knowledge management'. The present articlewill draw on concepts of cultural-historicalactivity theory to discuss the problem of howthe notion of ``knowledge' is conceptualized andimplicitly implemented in computer systems tosupport knowledge management, often neglectingthe social embeddedness of knowledge productionin everyday work practices. From the point ofview of cultural-historical activity theory wewould propose to look upon the generation ofknowledge as a process embedded in sociallydistributed activities that are constantlybeing reproduced and transformed in and betweenspecific communities of practice. We willpresent a model of cooperation that relatesprocessual and structural aspects of jointactivity. Methodologically, it draws on theanalysis of unexpected events in the course ofjoint activity. Our model also proposes to useforums for co-construction to make visibledifferent perspectives in the process ofsoftware design. The concept of cooperativemodel production is highlighted as a means tomediate, not to eliminate, differences ofperspectives involved in the course of systemsdesign. An empirical example will be given inwhich the repertory-grid technique is used tovisualize similarities and differences ofpotential users' viewpoints and requirements inearly stages of systems design.
