Battles for technological dominance: an integrative framework 总被引:3,自引:0,他引:3
Fernando F. Suarez 《Research Policy》2004,33(2):271-286
This paper proposes an integrative framework for understanding the process by which a technology achieves dominance when “battling” against other technological designs. We focus on describing the different stages of a dominance battle and propose five battle milestones that in turn define five key phases in the process. We review the literature from several disciplines to identify the key firm- and environment-level factors that affect the outcome of a technology battle and posit that the relative importance of each factor will vary depending on the phase considered. Our framework complements and extends existing literature and has implications both for theory and for management practice. 相似文献

A number of studies have concluded that when students have greater confidence about their math skills and are aware of its
usefulness, they have a more positive perception of the subject. This article aims to examine whether this pseudo linear trend
in the relationship between affective and instrumental dimensions is also true of the university context. Special attention
is devoted to the articulation of these dimensions in structuring student perceptions of quantitative methods so as to identify
the various forms that this interaction can assume. Our second aim is to understand how the perceptions of these subjects
are constructed by students from degree courses in distinct scientific areas. Can we speak of group dynamics whereby socialization
within each degree course triggers the sharing of similar perceptions? We concluded that a certain linear trend can also be
identified in the university context in the relationship between the affective dimension and usefulness of quantitative methods
i.e., that the highest levels in the perception of the usefulness of these subjects corresponded to the highest levels of
self confidence and enjoyment of the subjects. However, in addition to this scenario there is another configuration in which
negative feelings coexist with the recognition of the usefulness of quantitative methods subjects. Namely, lower levels of
self confidence and enjoyment of these subjects can also be associated with high levels of perceived usefulness. We also concluded
that there is evidence of what we designated a certain course culture in the perceptions about quantitative methods. Nevertheless,
when our observation is extended to the scientific area the heterogeneity of the perceptions becomes evident. Another important
finding is the rejection of the thesis, at least in the university context, that defends the lack of self-confidence in quantitative
methods among females student. 相似文献

Mapping the importance of the real world: The validity of connectivity analysis of patent citations networks 总被引:1,自引:0,他引:1
Recent empirical findings have questioned the use of patent citations as a measure. This points to the need of validation of patent citations methodologies, which we address by testing a recent methodology for studying technological evolution, namely connectivity analysis of citation networks. We find connectivity analysis to be a valid tool to identify the reliable knowledge which opens the way to further technological evolution of a surgical prosthesis, the artificial spinal disc. We also illustrate how connectivity analysis represents how this reliable knowledge differs depending on the stage of technological evolution. The corroborated validity of connectivity analysis of patent citations may trigger a renaissance in the use of this kind of patent data. 相似文献

The core of the Senate Bill 2042 (1998) was designed to provide the guidelines needed to prepare teachers who can meet the needs of a diverse K-12 student population in California. Following the guidelines marked by this bill, faculty working in Teacher Credential Programs across California are designing activities to prepare candidates with a deep understanding of effective pedagogies applicable to a full range of students. A key component in this preparation is to provide teacher candidates with opportunities to critically read and reflect on theory and research. Understanding the importance of this component, I designed an assignment, Quadruple Entry Journals (QEJ), which asks teacher candidates to first, critically read texts on theory; secondly, to reflect and analyze those texts; thirdly, to reflect on the reflections of their classmates; and, finally, to connect these theoretical reflections with practice. In this article, I explain the pedagogy followed when implementing QEJ with teacher candidates. Their feedback showed that when theory and research are cooperatively analyzed by teacher candidates, they better understand the connection between theory and practice, thus creating a deep understanding of what to teach and how to teach. 相似文献
