Publication and patent behaviour of academic researchers: conflicting, reinforcing or merely co-existing?.

Increasing entrepreneurial activity within academia has raised concerns that the amount of publications added to the scientific commons might become reduced or that academic research would become directed exclusively towards the application-oriented needs of industry. In the case of academic inventions, the potential conflict between public and private oriented considerations seems most salient. With this contribution, we examine whether the publication behaviour of academic inventors (at K.U.Leuven) differs from their colleagues (non-inventors) working within similar fields of research. Our analysis reveals that inventors publish significantly more. Moreover, no empirical evidence was found for the 'skewing problem'. These findings not only suggest the co-existence of both activities; they may actually reinforce one another.Academic investors; Field; Industry; Knowledge; Knowlegde interactions; Research; University-industry relations; Working;

Combining the production and the valorization of academic research: A qualitative investigation of enacted mechanisms.

The emergence of knowledge-based societies over the past decades has spurred research on the specific role of universities in innovation systems. The notion of academic entrepreneurship has gained acceptance among communities of researchers, practitioners and policy makers (Etzkowitz et al., 1998). At the same time, this acceptance seems impregnated by a constant alertness for the tensions that may arise. Concerns are uttered about shifts of the academic research agenda towards industry needs, resulting in fewer investments in basic research. Furthermore, the conflicting nature of the normative principles that guide academia and business has been warned for: competitive considerations and secrecy practices would stand in direct opposition to the principle of free dissemination of scientific knowledge (Dasgupta and David, 1987; Florida and Cohen, 1999; Geuna, 1999; Noble, 1977).Agency; Applicant; Assignee; Assignment; Business; Companies; Country; Data; EPO; Indicators; Information; Innovation; Institutional; Inventors; Methods; Order; Patent; Patent statistics; Patentee; Performance; Policy; Regions; Research; Researchers; Sector; Sector assignment; Technology; Time; University; USPTO; Innovation systems; Systems; Academic entrepreneurship; Community; Research agenda; Industry; Industries; Investments; Investment; Basic research; Principles; Dissemination; Knowledge;

Patent related indicators for assessing knowledge-generating institutions: towards a contextualised approach.

This contribution aims at examining the extent to which patent related indicators are relevant for shedding light on the notion of excellence within knowledge generating institutions. Traditionally, excellence has been looked upon as the ability to create interesting and valuable new scientific concepts, theories and data. From such a perspective, scientific excellence can be assessed through scientometric measures of publication output and impact. The recent interest in the 'entrepreneurial' phenomenon within knowledge generating institutes justifies efforts to examine the relevancy of broadening the set of indicators used to assess such institutions into the direction of entrepreneurial excellence. In this paper we will examine the relevancy of using patent data in order to delineate such additional, more entrepreneurial oriented, indicators. The arguments and findings presented in this respect will lead us to a plea for the use of these indicators in a contextualized manner.Science; Effectiveness; Patents; Country; Performance; Variance analysis;

On exponential ergodicity and spectral structure for birth-death processes, II

AbstractIn Part I, Feller's boundary theory was described with simple conditions for process classification. The implications of this boundary classification scheme for spectral structure and exponential ergodicity are examined in Part II. Conditions under which the spectral span is finite or infinite are established. A time-dependent norm is exhibited describing the exponentiality of the convergence and its uniformity. Specific systems are discussed in detail: Contents:1.7. Spectral structure for the M/M/I process2.8. Exponential ergodicity for processes with entrance, exit, and regular boundaries3.9. Exponential ergodicity for processes with natural boundaries4.10. Uniformity of exponential convergence5.11. Finite and Infinite spectral span6.12. Skip-free processes on the full lattic

Traces of prior art. An analysis of non-patent references found in patent documents.

Research in the area of innovation has pointed out the relevance of conceiving innovation as processes in which a multitude of actors and a variety of interactions play a role. Integrative notions like (national) innovations systems, (techno-scientific) networks, or the triple helix metaphor, have been widely accepted as relevant to grasp the complexities entailed. This development highlights the need for indicators that mirror the dynamics involved. This contribution presents an in-depth examination of the role of 'Non-Patent references', found in patents. After examining the occurrence of these references in the USPTO and EPO patent systems, the precise nature of these references is delineated by means of a systematic content analysis of two samples of non-patent references (n=10.000). Our observations reveal the relevance of 'non-patent references' for developing indicators to depict the proximity of technological and scientific developments. Application areas, limitations and directions for future research are discussed.Academic investors; Field; Industry; Knowledge; Knowlegde interactions; Research; University-industry relations; Working; Area; Innovation; Processes; Innovations; Systems; Networks; Triple-helix; Complexity; Indicators; Dynamics; Patents;

Combining entrepreneurial and scientific performance in academia: towards a compounded and reciprocal Matthew effect.

The increase of entrepreneurial activity within academia has raised concerns that the research orientation of universities might become 'contaminated' by the application-oriented needs of industry. Empirical evidence on this concern is scarce and ambiguous. We examine whether entrepreneurial and scientific performance in academia can be reconciled. Our empirical findings (K.U.Leuven, Belgium) suggest that both activities do not hamper each other; engagement in entrepreneurial activities coincides with increased publication outputs, without affecting the nature of the publications involved. As resources increase, this interaction becomes more significant, pointing towards a Matthew-effect. We finally suggest that balancing both activities further depends on the institutional policies deployed.Belgium; Industry; Innovation systems; Knowledge interactions; Performance; Policy; University;

National scientific capabilities and technological performance: An exploration of emerging industrial relevant research domains.

Today's theories and models on innovation stress the importance of scientific capabilities and science-technology proximity, especially in new emerging fields of economic activity. In this contribution we examine the relationship between national scientific capabilities, the science intensity of technology and technological performance within six promising industrial fields. Our findings reveal that national technological performance is positively associated with scientific capabilities. Countries performing better on a technological level are characterized both by larger numbers of publications and by numbers of involved institutions that exceed average expected values. The latter observation holds for both companies and knowledge generating institutes actively involved in scientific activities. As such, our findings seem to suggest beneficial effects of scientific capabilities shouldered by a multitude of organizations. In addition, higher numbers of patent activity coincide with higher levels of science intensity pointing out the relevance of science 'proximity' when developing technology in newer, emerging fields. Limitations and directions for further research are discussed.Performance; Research; Theory; Models; Model; Innovation; Field; Science; Intensity; Technology; Country; Expected; Value; Companies; Knowledge; Effects;

Passagem Retrógrada Percutânea De Uma Lesão Estenosante Crítica Do Tronco Celíaco Via Artéria Mesentérica Superior Como Manobra Adjuvante Na Abordagem Anterógrada

We describe the case of a 63-year-old woman with chronic mesenteric ischemia, persistent postprandial upper abdominal pain and progressive weight loss. Retrograde recanalization was performed via the superior mesenteric artery in order to achieve the goal of crossing the near-occlusion, showing that retrograde catheterization of the celiac trunk can be a feasible approach in challenging cases in which an antegrade approach fails as a single maneuver. © 2016, Sociedade Brasileira de Angiologia e Cirurgia Vascular.
