A man on the inside: Unlocking communities as complementary assets     

Linus Dahlander 《Research Policy》2006,35(8):1243-1259

Since Teece's seminal paper explaining who were the gainers from technological innovation, increased globalization and the information and communication technology revolution have brought new ways for firms to organize and appropriate from innovation. A new more open model of innovation suggests that firms can benefit from sources of innovation that stem from outside the firm. The central theme of this paper is how firms try to unlock communities as complementary assets. These communities exist outside firm boundaries beyond ownership or hierarchical control. Because of practices developed by communities to protect their work, firms need to assign individuals to work in these communities in order to gain access to developments and, to an extent, influence the direction of the community. Using network analysis we show that some software firms sponsor individuals to act strategically within a free and open source software (FOSS) community. Firm sponsored individuals interact with more individuals than interact with them, and also they seek to interact with central individuals in the community. However, we can see differences in how individuals interact, depending on whether their affiliation is with a dedicated FOSS firm or an incumbent in the software industry. Apparently, some firm managers believe they need ‘a man on the inside’ to be able to gain access to communities.  相似文献

Copyright or copyleft?: An analysis of property regimes for software development   总被引：3，自引：0，他引：3  

Paul B. de Laat   《Research Policy》2005,34(10):1511-1532

Two property regimes for software development may be distinguished. Within corporations, on the one hand, a Private Regime obtains which excludes all outsiders from access to a firm's software assets. It is shown how the protective instruments of secrecy and both copyright and patent have been strengthened considerably during the last two decades. On the other, a Public Regime among hackers may be distinguished, initiated by individuals, organizations or firms, in which source code is freely exchanged. It is argued that copyright is put to novel use here: claiming their rights, authors write ‘open source licenses’ that allow public usage of the code, while at the same time regulating the inclusion of users. A ‘regulated commons’ is created. The analysis focuses successively on the most important open source licenses to emerge, the problem of possible incompatibility between them (especially as far as the dominant General Public License is concerned), and the fragmentation into several user communities that may result.  相似文献   

Overview of Preventive Conservation Research Work on Seismic Mitigation and Subway Vibration Control in Chengdu Museum of China     

Sheng Yang  Jiaqi Ge  Mingbin Li  Ling Zhang  Chen Min 《文物保护研究》2020,65(4):212-220

ABSTRACT

The 2008 Wenchuan earthquake brought numerous issues to the attention of researchers of seismic mitigation in Chinese museums. After the Wenchuan earthquake, the structural design team of Chengdu Museum conducted a series of research projects on seismic mitigation and subway vibration control design of buildings. These projects included the following topics: optimization of design, numerical simulation of seismic performance, analysis of key technologies for the base isolation structure, in-depth studies on structural vibrations caused by the nearby subway, and proposals for reducing structural vibrations. In 2015, after the superstructure of Chengdu Museum was completed, conservators evaluated the safety of permanent exhibitions under earthquake conditions. Seismic protection devices were installed on the showcases according to the preventive conservation requirements for museum collections. Reinforced measures were used for museum collections according to the methods suggested in the document ‘Specification for seismic protection of museum collection’ (WW/T 0069-2015). The conservators also built a systematic platform for earthquake monitoring for museum collections. Preventive conservation studies on seismic protection and subway vibration control in Chengdu Museum are summarized and forecasted.  相似文献   

城乡全科医生信息源与互联网信息障碍比较     

谢娟  张媛  成颖  柯青 《图书馆论坛》2020,(2):90-98

文章旨在探讨城乡全科医生信息源以及互联网信息障碍的差异,以推进有针对性地为城乡全科医生提供优质的医疗信息服务,提高其医疗水平和服务能力。文章采用问卷调查法,通过便利采样在城市和农村的基层医疗机构回收有效问卷150份,并对采集到的数据进行统计分析。结果显示,城市和农村全科医生信息源的多样性及偏好并无显著差异,其对大部分信息源的感知有用性也趋同;但他们对同行信息源和非正式文件的感知有用性存在显著差异。互联网的使用频率、自我感知使用能力、接受互联网培训以及通过医疗网站为病人诊断等情况在城乡全科医生之间也无显著差异。在互联网信息障碍方面,城市和农村的全科医生都遇到了网络连接太慢以及软件问题;此外,农村全科医生还面临着语言障碍、缺乏熟悉度或经验以及信息过载等障碍。据此,文章提出,要重点提高农村全科医生的信息素养;大力发展全科医生的医学教育;进行城乡全科医生互联网技能培训,但由于城乡中基础设施和全科医生教育背景的差异,培训的内容和形式也要因地制宜、因人而异;加强互联网医疗信息资源建设;合理进行农村基层医疗机构的软硬件配置。  相似文献   

南北朝隋唐时期画家的创作心态与文化支持     

孙兆俊 《滨州学院学报》2007,23(4):39-41

南北朝隋唐时期的绘画理论,对冠绝当代、后世宗承的画家及其创作多有评述,这为探视古代画家的创作心态提供了有利的依据。古代画家"守其神,专其一"的心态修持,是儒释道文化集中影响的结果。魏晋南北朝及隋唐时期,古代画家在儒释道文化相互融合的环境下,广泛汲取儒释道文化中有关心态修持的思想成果,从而为绘画心态的修持以及理想境界的探索提供了丰富的途径和方法。  相似文献
