The citation network of the International Journal of Research in Marketing (IJRM) is examined from 1981 to 1995. We propose a model that contains log-linear and logmultiplicative terms to estimate simultaneously the importance, cohesion, and structural equivalence of journals in the network across time. Our findings show that the overall importance of IJRM in its network is low but growing. The...

Although in rough agreement on the rating of two-thirds of the journals, the deans and directors differ significantly on the ratings of the remaining one-third. The subset of ARL directors in institutions where librarians have ...

Retraction notices appear regularly in many scholarly journals, especially top-tier journals of science and engineering. One disconcerting feature of this emergent genre is evasion of authorship, that is, the deliberate obscuring of who has authored a particular retraction notice. This communication illustrates and discusses problems of evaded authorship of retraction notices. To address these ...

Neurosurgery journals have played an active role in improving the quality of the neurosurgical literature. This role has expanded to improve the quality of care by incorporating an evidence-based view of neurosurgery practice. Neurosurgery journals have facilitated the organization of knowledge into clinically useful forms via the publication of meta-analyses and dissemination of clinical pract...
