近年来,专利引文越来越多地被用于技术路径研究、技术会聚、技术扩散等技术领域间的知识活动研究,但并未有效区分申请人引用和审查员引用,现有技术领域层面对申请人和审查员引用差异的对比研究还停留在较为浅显的统计层面。将技术类别间的差异性引入到申请人引用和审查员引用的对比研究中,在技术类别分布基础上,探究专利技术类别多样性视角下申请人引用和审查员引用的知识来源差异,并对其开展相关性分析。研究结果表明:专利申请人引用涉及的技术类别范围更广,而审查员引用则更集中于本技术类别;对大部分技术类别,申请人引用的技术类别多样性要高于审查员引用,但两者呈现出显著的正相关性。  相似文献

知识转移是企业保存知识、提升创新能力的重要途径,中介机构在转移过程中发挥了重要作用。本文以联盟企业间知识转移为研究对象,考虑了企业的不同心理压力,首先建立了联盟企业双方的讨价还价博弈模型;其次构建了考虑中介机构参与知识转移的博弈模型,分析和讨论三方收益变化的影响因素及策略选择。结果表明,在直接知识转移博弈中,转移主体的收益大小与自身的心理压力呈负相关,而与对方的心理压力呈正相关,同等心理压力下知识转出方占优;中介机构参与博弈情形下,中介机构作为协作角色的博弈收益仅受博弈双方心理压力影响,且与知识接收方协作可获得更大收益,而主导角色博弈情形下收益受到三方主体心理压力的综合影响,并在主导知识接收博弈时获得收益更大;中介机构的角色选择与知识转出方心理压力变化相关性不明显,主要受到知识接收方及自身心理压力影响。  相似文献

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation.  相似文献

以知识流动为研究视角,将集群创新过程中的知识溢出、吸收能力内生化,构建包含三种创新模式下的产业集群演化模型,重点分析集群知识分布和知识衰减程度与集群创新模式的内在机制及其对创新产出的影响,并进行仿真实验。研究表明:不同知识分布下,混合创新模式的创新产出表现最好,外部吸收创新模式与内部自主创新模式呈现出不同的创新产出演化路径;在外部吸收创新和混合创新模式下,均匀分布型产业集群的创新产出表现最好,集中分布型表现次之,异质分布型表现最差,而在内部自主创新模式下,集中分布型则表现最好;不同创新模式对知识衰减的敏感程度呈现阶段性差异特征。这些结论对产业集群创新和可持续发展具有很好的理论和实践指导意义。  相似文献

实习教师隐性知识显性化能有效促进实习教师个体教学经验的积累和理论知识的增长,增加教育实习的价值。当下,我国学者对教师隐性知识的研究对象更多集中于资深教师团体。由于实习教师隐性知识外显化缺少必要的机制与条件,所以学者们往往忽略了对实习教师隐性知识显性化的挖掘。SECI模型指知识转化的四种模式,即社会化、外部化、组合化和内部化。与之相对应的有四种场所,分别是创始场、对话场、系统化场和练习场。在此基础上,提出SECI知识转换扩展模型,并从知识创生的四个不同阶段探究实习教师对SECI模型的应用情况。据此,提出相应的教育实习策略,如建立学习共同体、引导实习教师深入反思教学实践、建立有效的学校ICT环境、形成高效且自主的实习教师授课模式等,以促进隐性知识的共享与应用。  相似文献

This paper examines the relationship between professional work and standardization. There has been an increase in the use of standardized programmes in child welfare services (CWS) in Western society. Some researchers have criticized standardized programmes suggesting that they undermine professionals expertise and threaten their position, whereas others argue that such programmes strengthen professional practice. In this paper, we examine how standardized tools, in this case, a standardized parenting programme and a standardized Norwegian assessment tool, influence professional roles as experienced by child welfare workers (CWS professionals) in Norway. Semistructured individual and group interviews were conducted with 31 frontline workers in two CWS agencies. Our findings suggest that standardized tools increase the social workers experienced professional competence but challenge their professional knowledge base, reflective practice, and professional accountability. Professional and practical implications for CWS work are discussed in the light of these findings.  相似文献

布鲁尔强纲领中所反对的目的论模型来源于巴恩斯提出的目的论模式,他们都拒绝将科学的发展看作真理进化过程,认为作为一种信念的科学知识应当纳入知识社会学的研究领域。布鲁尔进一步提出了与目的论模型相对立的因果性模型,并构建出科学知识社会学应当遵守的四条“强纲领”,力图促使知识社会学成为一门普遍性的学科。布鲁尔声称强纲领的因果性模型与目的论模型是两种相互排斥的形而上学立场,但实际上因果性模型与目的论模型并不完全排斥,甚至还有所交融;同时,他关于因果性模型的论证与辩护也存在诸多问题,是一种不彻底的“强纲领”。  相似文献

Abstract

Objective: This study examines the prevalence and risk factors associated with risky sexual behaviors in community college students. Participants: A diverse sample of 18–19-year-old community college students (N?=?264). Methods: Baseline data from an online prevention program administered in 2015. Results: Community college students in this sample disproportionately experienced sexual assault and were unlikely to test for STIs. Higher intentions to engage in risky sexual behaviors were associated with gender and sexual experience, but also with having lower intentions to communicate with a sexual partner about pregnancy and STIs, and having higher gender norm endorsement. Conclusions: Older adolescents attending community colleges may be at high risk for poor sexual health outcomes, and appropriate theory-based education should be tailored to meet the needs of these underserved students.  相似文献

ABSTRACT

One overarching question in scholarly methodological discussions on qualitative comparative approaches concerns how it is possible to compare and generalise deep insider knowledge across (nationally) specific contexts. The aim of this article is to propose a research strategy that both facilitates the comparison and theorisation of such knowledge across nations and limits the risks of reproducing naturalised national ‘truths’. The strategy is developed within a feminist, cross-national, qualitative comparative analysis of how European countries addressed military deaths in connection with the ISAF mission in Afghanistan. The article underlines the importance of collective analytical work and of strategies that allow continuous movement between insider and outsider positions throughout the research process. A number of analytical strategies are presented: collective project design, alternating between analytical closeness and distance, and de-familiarising writing practices.  相似文献

ABSTRACT

This paper is about the changing imaginations of social work in an increasingly entangled world. It is also about the ways in which literatures shared across time and space encourage us to identify with larger collectivities. My central argument is that if social work is to find a larger vision in the wake of the failure of a range of modern progress narratives, we must engage differently with the challenge posed by multiplying and sometimes conflicting knowledge communities. Thinking with contemporary debates in transdisciplinary critical social theory, I nominate and explore a number of alternative heuristics—‘generational problematic,’ ‘translational space,’ and ‘imagined communities’—in support of future work on the uneven temporal and spatial communities of affiliation that reproduce and change what social work is, or could be, about. I conclude with theoretical suggestions, and some thoughts toward how social work education might better support incoming generations to locate themselves within the broader life-course of the discipline and profession.  相似文献
