[EN]This paper examines a corpus of 150 titles of research articles published between 2010 and 2013 in Anglo-American natural sciences journals (physics, chemistry and biology) in order to determine their lexical density and grammatical and morphosyntactic features. Towards that end, the frequency of present and past participles, prepositions, coordinating and subordinate conjunctions, and the frequency and length of compound words was recorded in each title. The total number of content and function words was also recorded so as to determine title lexical density. ANOVA tests were applied in order to assess whether statistically significant differences in the frequency of the above mentioned variables were detected within and across disciplines and in the whole corpus.

[EN]This paper proposes an alternative bibliometric indicator for evaluating scholarly journals based on the percentage of highly cited articles in a journal. It compares such an index with the impact factor and the h-index by using different time windows and levels of citation that can determine when a document can be considered as highly cited compared to others of the same year and discipline. The main outcome of this comparison suggests that the best index for obtaining data distributions that are comparable between scientific fields is by taking the 20% citation percentile over a three-year time frame for considering citations.
