A new dimension in urban planning: the Big Data as a source for shared indicators of discomfort.
No full textThe web has been used for years as a means of expression for the local communities in highlighting their problems, needs and hopes, often in the form of organized group discussions and fora. The enormous amount of information currently available, Big Data, is already used for business purposes in the private sector, but has never been truly available to decision makers who operate in urban planning and would represent an invaluable help for those communities that undertake the path of selfconstruction of their Community Strategic Frameworks. This paper elaborates methodological and operational proposals to identify sequences of words and common occurrences in sets of documents that would help understanding the problems of the communities on a geographicallylocated basis, creating the search engine “Social Debate” and devising new indicators for indices of disadvantage. Such tool could drastically change the perspective of public participation and planning practice and improve the quality of local public policies and decision making processes

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.
