Culturally responsive computing as brokerage: toward asset building with education-based social movements

Bridging schools and communities has been a goal, if not hurdle, for reformers who aim to improve the education of low-income and underrepresented students from the bottom-up. Strategies to create these connections are often characterized as ‘brokerage’, where individuals or organizations bridge two or more social worlds. This paper details the design and implementation of educational technologies that support the brokering of school–community connections using a ‘culturally responsive computing’ (CRC) framework. Culturally responsive education is often limited to content and learning styles, which misses the opportunities it creates for a brokerage process that also connects to education-based social movements for economic access in underrepresented communities. This paper provides empirical support for the claim that the CRC framework is well suited for both purposes. It allows schools and communities to build assets together, translating the knowledge and skills of underrepresented communities into math and computing education, while illuminating the ways in which technologies can motivate education-based social movement building.     

专利权人引用网络中的媒介角色研究

对专利权人引用网络中的3种类型的媒介角色的概念、算法等进行梳理,根据媒介角色理论和知识交流理论对媒介角色是否影响专利权人技术创新能力做理论推导,并提出3个假设。通过实证分析发现,不同的角色影响程度各不相同:中介中心性对专利权人技术创新能力的影响力最大;5种桥系数小于中介中心性,影响最小的是结构洞约束。     

学术机构引证中的中介关系

本文研究学术机构引证网络中的中介关系,识别和分析以中间人作为纽带的中介路径以及中介模式。选取信息计量领域机构数据,依据P(Top 10%)指数将学术机构划分为“强”“中”“弱”三个学术实力等级,结合中间人中介关系分析,得出三条主要知识交流路径,按照显著程度,依次为“中→弱”“弱→弱”和“强→弱”。中介模式方面,“强”等级中间人机构发挥主导中介作用。显著路径末端的机构与对应的始端机构具有潜在的知识交流需求,双方可在重合的研究主题和研究方向上推进交流合作。图6。表8。参考文献26。     

A bridge over troubled waters: Bridging organisations and entrepreneurial opportunities in emerging sectors

Bridging institutions or organisations are regarded as having positive effects in the Sectoral Systems of Innovation (SSI) literature, particularly in compensating for weaknesses in these systems. Yet, we know little about the organisational practices that make their role effective, or the types of innovation paths that they may facilitate within a system. This paper shows how bridging organisations may promote neglected areas of creativity and potential disruptive innovation. These blocked opportunities tend to emerge at the boundaries of SSI: where old sectors overlap and new trajectories form. We draw on the social networks, entrepreneurship and disruptive innovation literature and analyse an intervention in the UK electronic games industry: the evaluation of business propositions exploiting new gaming platforms such as mobile telephones, DVD and film. Using an innovative co-productive research design, the study shows how the effectiveness of bridging organisation activity depends on key design choices and brokerage capabilities.     

Bridges or isolates? Investigating the social networks of academic inventors

We analyze the acquaintances of a sample of academic inventors and their paired controls to investigate the contribution of social networks to the generation of inventive ideas in academe. Prior to patenting, inventors work in networks of similar dimension and structure as those of their colleagues who do not invent. The ego-networks of the inventors are however more cohesive (denser), a circumstance that is often seen as associated to the exchange of more fine-grained information and to a greater climate of trust which facilitates long-term relationships and learning. Over time, both inventors and non-inventors extend their networks and become more central. In general, we found no evidence that after patenting inventors isolate or close their networks.

Vertical alliance networks: The case of university-biotechnology-pharmaceutical alliance chains

Many young biotechnology firms act as intermediaries in tripartite alliance chains. They enter upstream partnerships with public sector research institutions, and later form commercialization alliances with established, downstream firms. We examine the alliance activity in a large sample of biotechnology firms and find: (i) firms with multiple in-licensing agreements are more likely to attract revenue-generating alliances with downstream partners; however, (ii) the positive relationship between in-licenses and downstream alliances attenuates as firms mature, and (iii) the diversity and the quality of the academic connections of firms’ principals influences their chances of successfully acquiring commercialization rights to scientific discoveries in universities.
