Journal of Risk Research (from journals menu ESI) Social Science, General

Baseline data (from ESI) Article from 2003 in Social Science, general: Average: 7.04 citations,

10%: 18 citations, 1%: 56 citations RI= 57 / 7.04 = 8.1

Advanced bibliometric indicators

Follow van Raan (1996) as closely as possible; but..... Web of Science is used for citation data

We can’t make corrections for self citations Essential Science Indicators for baseline data (World

average, Top 10% and Top 1%) Limited number of research fields (22) Same baseline data used for selected document types

• (articles, reviews, notes and letters (and selected proceedings))

We can determine the representativeness of the citation analysis

Final word on Journal quality

It is better to publish one paper in a quality journal than multiple papers in lesser journals. [...]. Try to publish in journals that have high impact factors; chances are your paper will have high impact, too, if accepted.

Wuchty, S., B. F. Jones, et al. (2007). The increasing dominance of teams in production of knowledge. Science 316(5827): 1036-1039.

Teams increasingly dominate solo authors in the production of knowledge. Research is increasingly done in teams across nearly all fields.

Teams typically produce more frequently cited research than individuals do, and this advantage has been increasing over time.

Teams now also produce the exceptionally high-impact research, even where that distinction was once the domain of solo authors.

Self citations

Self citations

The model [...] implies that external citations are enhanced by self-citations, so that we have the “chain reaction:” Larger size leads to more self-citations, which lead to more external citations.
