Innovation: A Guide to the Literature

Innovation is not a new phenomenon. Arguably, it is as old as mankind itself. However, in spite of its obvious importance, innovation has not always got the scholarly attention it deserves. This is now rapidly changing, however. As shown in the paper, research on the role of innovation economic and social change has proliferated in recent years, particularly within the social sciences, and often with a bent towards cross-disciplinarity. It is argued that this reflects the fact that no single discipline deals with all aspects of innovation, and that in order to get a comprehensive overview of the role played by innovation in social and economic change, a cross-disciplinary perspective is a must. The purpose of the paper is to provide the reader with a guide to this rapidly expanding literature. In doing so it draws on larger collective effort financed by the European Commission (the TEARI project), one of the outputs of which will emerge as Oxford Handbook of Innovation, edited by Jan Fagerberg, David Mowery and Richard R. Nelson.

Weak Instruments: A Guide to the Literature

Weak instruments have become an issue in many contexts in which econometric methods have been used. Some progress has been made into how one diagnoses the problem and how one makes an allowance for it. The present paper gives a partial survey of this literature, focussing upon some of the major contributions and trying to provide a relatively simple exposition of the proposed solutions.

Using open access literature to guide full-text query formulation

*Background*
Much scientific knowledge is contained in the details of the full-text biomedical literature. Most research in automated retrieval presupposes that the target literature can be downloaded and preprocessed prior to query. Unfortunately, this is not a practical or maintainable option for most users due to licensing restrictions, website terms of use, and sheer volume. Scientific article full-text is increasingly queriable through portals such as PubMed Central, Highwire Press, Scirus, and Google Scholar. However, because these portals only support very basic Boolean queries and full text is so expressive, formulating an effective query is a difficult task for users. We propose improving the formulation of full-text queries by using the open access literature as a proxy for the literature to be searched. We evaluated the feasibility of this approach by building a high-precision query for identifying studies that perform gene expression microarray experiments.

*Methodology and Results*
We built decision rules from unigram and bigram features of the open access literature. Minor syntax modifications were needed to translate the decision rules into the query languages of PubMed Central, Highwire Press, and Google Scholar. We mapped all retrieval results to PubMed identifiers and considered our query results as the union of retrieved articles across all portals. Compared to our reference standard, the derived full-text query found 56% (95% confidence interval, 52% to 61%) of intended studies, and 90% (86% to 93%) of studies identified by the full-text search met the reference standard criteria. Due to this relatively high precision, the derived query was better suited to the intended application than alternative baseline MeSH queries.

*Significance*
Using open access literature to develop queries for full-text portals is an open, flexible, and effective method for retrieval of biomedical literature articles based on article full-text. We hope our approach will raise awareness of the constraints and opportunities in mainstream full-text information retrieval and provide a useful tool for today’s researchers.

[Review of] Julio A. Martinez and Francisco A. Lomeli. Chicano Literature: A Reference Guide

The editors in attempting to cover Chicano literature written since 1848 by Americans of Mexican descent have done a fine service for all students of American literature whether they are specialists or generalists, tyros or scholars. The work in more than one way provides a comprehensive reference guide
