On the value of Digital Traces for commercial strategy and public policy: Telecommunications data as a case study
No full textJust as information and communication technologies (ICT) and the digital economy are transforming everyday life, so they are transforming our ways of knowing about everyday life. The breadth of social practices that are mediated by digital infrastructure, and thus recorded by digital traces, has not gone unnoticed in the social sciences.1 Coupled with technological and methodologi- cal advances in large-scale data capture, storage, and analysis, transactional data on communication, con- sumption, leisure, health, work, and education are now routinely collected and can, in principle, be employed for a wide range of analyses. Clearly, the increased traceability of social networks can enhance our ability to extract actionable insight by analyzing their form, distribution, and structure through digital media. Consequently, an enormous potential to generate important insights and innovation exists within the social sciences through an improved understand- ing of spatialized social networks (i.e., place-based analyses of social network structures over time). As we will show, these networks have applications in—at the very least—regional development, market research, and infrastructure planning because the structure and spatial distribution of social networks underpins demand (and, consequently, supply or provisioning) as well as provides indicators of well-being, integration, and cohesion
Introduction
No full textThe growth of a research field depends on the quality of the research it produces. The Emerging Adulthood Series, collecting books about flourishing and floundering in emerging adulthood, has already done an excellent job of communicating and disseminating the latest findings in the emerging adulthood research field. It also provides support for researchers in expanding their knowledge of the field and producing new research on emerging adulthood. However, in addition to deepening the understanding of the central themes in emerging adulthood research, such as marriage, spirituality, identity, and personality, this positive trend can be further strengthened by offering information about the “how” of the research process (i.e., the means by which the findings in this field are produced). While we recognize that the likely readers of this book already have sufficient skills in some particular methodologies, we also see that the methods used in emerging adulthood research are especially diverse and often involve quantitative cross-sectional, quantitative longitudinal, quantitative multi-informant, intensive longitudinal, qualitative, and mixed methods investigations. More so, studying emerging adults often presents specific challenges. For example, given the high demographic instability, obtaining a diverse and representative sample of emerging adults is more difficult than in other areas of human research. Considering these and other issues in emerging adulthood research, we believe a research methods book tailored to the study of emerging adulthood offers a set of advantages over other books on more general research methodology
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
