Titles in English-medium Astrophysics research articles

Abstract: In this study we analyse a corpus of 300 randomly selected research paper titles written in English and published between 1998 and 2012 in the most prestigious journals in the field of Astrophysics, an under-researched discipline from a linguistic standpoint. We specifically address issues related to the evolution of titles, their length, their lexical density, their type distribution and their semantic content. Our findings reveal a trend towards relatively long titles with a high lexical density, a preference for nominal and simple titles over verbal and compound ones, a very low occurrence of question constructions, and a prevalence of purpose and results over methods as key research concepts expressed in titles. We compare our findings with the results of previous studies on titles in other scientific disciplines and provide explanations for the differences and similarities observed.

Simultaneous and Comparable Numerical Indicators of International, National and Local Collaboration Practices in English-Medium Astrophysics Research Papers.

Abstract: Introduction We report an investigation on collaboration practices in research papers published in the most prestigious English-medium astrophysics journals Method We propose an evaluation method based on three numerical indicators to study and compare, in absolute terms, three different types of collaboration (international, national and local) and authors' mobility on the basis of co-authorship AnalysisWe analysed 300 randomly selected research papers in three different time periods and used the student's t-test to determine whether the paired two-sample differences observed were statistically significant or not Results International collaboration is more common than national and local collaboration International, national and local authors' mobility and intra-national collaboration do not seriously affect the indicators of the principal levels of collaboration International collaboration and authors' mobility are more relevant for authors publishing in European journals, whereas national and intra-national collaboration and national mobility are more important for authors publishing in US journals Conclusions We explain the observed differences and patterns in terms of the specific scope of each journal and the socio-economic and political situation in both geographic contexts (Europe and the USA) Our study provides a global picture of collaboration practices in astrophysics and its possible application to many other sciences and fields would undoubtedly help bring into focus the really big issues for overall research management and policy

The relationship between manuscript title structure and success: editorial decisions and citation performance for an ecological journal.

Abstract: A poorly chosen article title may make a paper difficult to discover or discourage readership when discovered, reducing an article's impact. Yet, it is unclear how the structure of a manuscript's title influences readership and impact. We used manuscript tracking data for all manuscripts submitted to the journal Functional Ecology from 2004 to 2013 and citation data for papers published in this journal from 1987 to 2011 to examine how title features changed and whether a manuscript's title structure was predictive of success during the manuscript review process and/or impact (citation) after publication. Titles of manuscripts submitted to Functional Ecology became marginally longer (after controlling for other variables), broader in focus (less frequent inclusion of genus and species names), and included more humor and subtitles over the period of the study. Papers with subtitles were less likely to be rejected by editors both pre- and post-peer review, although both effects were small and the presence of subtitles in published papers was not predictive of citations. Papers with specific names of study organisms in their titles fared poorly during editorial (but not peer) review and, if published, were less well cited than papers whose titles did not include specific names. Papers with intermediate length titles were more successful during editorial review, although the effect was small and title word count was not predictive of citations. No features of titles were predictive of reviewer willingness to review papers or the length of time a paper was in peer review. We conclude that titles have changed in structure over time, but features of title structure have only small or no relationship with success during editorial review and post-publication impact. The title feature that was most predictive of manuscript success: papers whose titles emphasize broader conceptual or comparative issues fare better both pre- and post-publication than do papers with organism-specific titles.
