Nanotechnology research in Turkey: A university-driven achievement

We deal with nanotechnology research activities in Turkey. Based on publication data retrieved from ISI Web of SSCI database, the main actors and the main characteristics of nanotechnology research in Turkey are identified. Following a brief introduction to nanoscience and nanotechnology research, it goes on with a discussion on nanotechnology related science and technology policy efforts in developing countries and particularly in Turkey. Then using bibliometric methods and social network analysis techniques, this paper aims to understand the main actors of the nanoscale research in Turkey and how they collaborate across institutes and disciplines. The research indicates that there has been an exponential growth in the number of research articles published by Turkish nanoscience and nanotechnology (NST) scholars for the last ten years. However, the analysis of the main characteristics of nanotechnology research carried out at Turkish universities indicates some drawbacks and barriers to the future development of nanotechnology research in Turkey. These barriers are (i) a high concentration of nanoscale research at certain universities; (ii) low level of interdisciplinarity; (iii) a large number of universities which are not well connected to other universities in the field, and finally (iv) low level of international collaborations. Finally, science and technology policy implications of this research are discussed in the conclusion.Emerging technologies nanotechnology, nanoscience, scientific publications, SSCI, bibliometric data, social network analysis, collaborations, interdisciplinarity, science and technology policies, emerging economies, Turkey.

The Local Emergence and Global Diffusion of Research Technologies: An Exploration of Patterns of Network Formation

Grasping the fruits of "emerging technologies" is an objective of many government priority programs in a knowledge-based and globalizing economy. We use the publication records (in the Science Citation Index) of two emerging technologies to study the mechanisms of diffusion in the case of two innovation trajectories: small interference RNA (siRNA) and nano-crystalline solar cells (NCSC). Methods for analyzing and visualizing geographical and cognitive diffusion are specified as indicators of different dynamics. Geographical diffusion is illustrated with overlays to Google Maps; cognitive diffusion is mapped using an overlay to a map based on the ISI Subject Categories. The evolving geographical networks show both preferential attachment and small-world characteristics. The strength of preferential attachment decreases over time, while the network evolves into an oligopolistic control structure with small-world characteristics. The transition from disciplinary-oriented ("mode-1") to transfer-oriented ("mode-2") research is suggested as the crucial difference in explaining the different rates of diffusion between siRNA and NCSC

A Map of the Nanoworld: Sizing up the Science, Politics, and Business of the Infinitesimal

Mapping out the eight main nodes of nanotechnology discourse that have emerged in the past decade, we explore how various scientific, social, and ethical islands of discussion have developed, been recognized, and are being continually renegotiated. We do so by (1) identifying the ways in which scientists, policy makers, entrepreneurs, educators, and environmental groups have drawn boundaries on issues relating to nanotechnology; (2) describing concisely the perspectives from which these boundaries are drawn; and (3) exploring how boundaries on nanotechnology are marked and negotiated by various nodes of nanotechnology discourse.Comment: 25 page

Organising the socio-economic relevance of university research: the case of nanomaterials research in Taiwan

This thesis is concerned with academics’ behaviour when organising research aimed at being relevant. More specifically, this study combines a sociological approach and an extensive bibliometric analysis, investigating the relationships between scientists’ perceptions of relevance, their research behaviours and their publishing activities in terms of organising nanomaterials research in Taiwan. By introducing a resource-based concept of the notion of relevance from a scientist’s perspective, it contributes to intellectual debates on changes to knowledge production and the relationship between scientific excellence and socio-economic relevance. The study finds that the ways nanomaterials scientists perceive and organise their research, specifically in terms of research orientation, industry involvement and interdisciplinary collaboration, are not entirely oriented towards socio-economic concerns. Scientists tend to adapt to the demand for relevance by demonstrating potential research applications and forming interdisciplinary collaborations. Nevertheless, they are more persistent in terms of not having industry involved in the research process. Balancing adaptation and persistence reflects scientists’ concerns with securing financial, intellectual and symbolic resources in order to establish their academic credibility. The bibliometric analysis broadly confirms the qualitative results findings, showing an increasing trend towards publishing in applied and targeted basic journals, and towards interdisciplinary collaboration. Yet, the proportion of university-industry papers has been rather stable over time. While our interviews suggest that senior scientists tend to consider interdisciplinary collaboration as a way to facilitate application, the bibliometric analysis shows that interdisciplinary co-authored papers tend to be more basic and receive more citations. The analysis also finds that junior scientists tend to feel more pressure to achieve a strong academic performance, thereby pushing them away from activities concerning achieving the envisioned socio-economic relevance of their research. Given the ambiguous notion of relevance and the inconsistency of policy practices, this thesis suggests that the real pressure is more to do with the demand for excellence than for relevance

Diversity and network coherence as indicators of interdisciplinarity: Case studies in bionanoscience

The multidimensional character and inherent conflict with categorisation of interdisciplinarity makes its mapping and evaluation a challenging task. We propose a conceptual framework that aims to capture interdisciplinarity in the wider sense of knowledge integration, by exploring the concepts of diversity and coherence. Disciplinary diversity indicators are developed to describe the heterogeneity of a bibliometric set viewed from predefined categories, i.e. using a top-down approach that locates the set on the global map of science. Network coherence indicators are constructed to measure the intensity of similarity relations within a bibliometric set, i.e. using a bottom-up approach, which reveals the structural consistency of the publications network. We carry out case studies on individual articles in bionanoscience to illustrate how these two perspectives identify different aspects of interdisciplinarity: disciplinary diversity indicates the large-scale breadth of the knowledge base of a publication; network coherence reflects the novelty of its knowledge integration. We suggest that the combination of these two approaches may be useful for comparative studies of emergent scientific and technological fields, where new and controversial categorisations are accompanied by equally contested claims of novelty and interdisciplinarity.Comment: 28 pages, 8 figure

Betweenness and Diversity in Journal Citation Networks as Measures of Interdisciplinarity -- A Tribute to Eugene Garfield --

Journals were central to Eugene Garfield's research interests. Among other things, journals are considered as units of analysis for bibliographic databases such as the Web of Science (WoS) and Scopus. In addition to disciplinary classifications of journals, journal citation patterns span networks across boundaries to variable extents. Using betweenness centrality (BC) and diversity, we elaborate on the question of how to distinguish and rank journals in terms of interdisciplinarity. Interdisciplinarity, however, is difficult to operationalize in the absence of an operational definition of disciplines, the diversity of a unit of analysis is sample-dependent. BC can be considered as a measure of multi-disciplinarity. Diversity of co-citation in a citing document has been considered as an indicator of knowledge integration, but an author can also generate trans-disciplinary--that is, non-disciplined--variation by citing sources from other disciplines. Diversity in the bibliographic coupling among citing documents can analogously be considered as diffusion of knowledge across disciplines. Because the citation networks in the cited direction reflect both structure and variation, diversity in this direction is perhaps the best available measure of interdisciplinarity at the journal level. Furthermore, diversity is based on a summation and can therefore be decomposed, differences among (sub)sets can be tested for statistical significance. In an appendix, a general-purpose routine for measuring diversity in networks is provided
