Abstract:
A large number of papers related to oral and maxillofacial surgery are published in many specialist journals. With the ever-increasing use of the internet it is easy to download them as part of a journal subscription on a fee per paper basis, or in some cases for free. Online access to the British Journal of Oral and Maxillofacial Surgery (BJOMS) is free to British Association (BAOMS) members with a $30 fee per paper down:toad for non-members. Many colleagues use the online version of the journal, and this provides valuable information about downloading trends. Other data on articles that have been cited in subsequent publications are also readily available, and they form the basis for the calculation of a journal's *impact factor*.
We evaluated the top 50 downloaded papers from the BJOMS website in 2010 to ascertain which articles were being read online. We also obtained data on the number of citations for papers published in 2009-2010 to see whether these papers were similar to the articles being downloaded. In 2010 there were over 360 000 downloaded articles. The most popular papers were leading articles, reviews, and full length articles; only one short communication featured in the top 50 downloads. The papers most cited in subsequent publications were full length articles and leading articles or reviews, which represent 80% of the total citations of the 50 papers. Ten papers were in both the top 50 downloaded and most cited lists. We discuss the implications of this study for the journal and our readers.

Abstract:
Citation distributions are crucial for the analysis and modeling of the activity of scientists. We investigated bibliometric data of papers published in journals of the American Physical Society, searching for the type of function which best describes the observed citation distributions. We used the goodness of fit with Kolmogorov-Smirnov statistics for three classes of functions: log-normal, simple power law and shifted power law. The shifted power law turns out to be the most reliable hypothesis for all citation networks we derived, which correspond to different time spans. We find that citation dynamics is characterized by bursts, usually occurring within a few years since publication of a paper, and the burst size spans several orders of magnitude. We also investigated the microscopic mechanisms for the evolution of citation networks, by proposing a linear preferential attachment with time dependent initial attractiveness. The model successfully reproduces the empirical !
 citation distributions and accounts for the presence of citation bursts as well.

Abstract:
The authors collected the numbers of citations and downloads from 2005 to 2009 of papers in five Chinese general ophthalmological journals: Recent Advances in Ophthalmology, Chinese Ophthalmic Research, Ophthalmology in China, Journal of Clinical Ophthalmology and Chinese Journal of Practical Ophthalmology, published in 2005 from the Chinese Academic Journals Full-text Database and the Chinese Citation Database in Chinese National Knowledge Infrastructure (CNKI) to determine the correlation between download and citation and the peak time of download frequency (OF). The citations from 2000 to 2009 of papers published in 2000 were collected to determine the peak time of citation frequency (CF) of medical papers. There is a highly positive correlation between OF and CF (r = 4.91, P = 0.000). Serials Review 2011; 37:157-161. (C) 2011 Elsevier Inc. All rights reserved.

Abstract:
This study investigates self-citation rates of 222 Chinese journals within seven groups including 76 journals of agronomy (34.2 percent), 57 of biology (25.7 percent), 28 of environmental science and technology (12.6 percent), 15 of forestry (6.8 percent), 24 of academic journals of agricultural university (10.8 percent), 9 of aquatic sciences (4.1 percent), and 13 of animal husbandry and veterinary medicine (5.9 percent). The average self-citation rates range from 2 percent to 67 percent in 2006, 1 percent to 68 percent in 2007 and 0 percent to 67 percent in 2008. There is a significant difference in self-citation rate between most groups of journals. The self-citation rate is positively and significantly correlated with the self-citation rate in 2006 for all 222 journals (N = 222, R(2) = 0.194, P = 0.004) (P<0.05). However, the self-citation rate is not significantly correlated with the journal's *impact factor* in 2007 (N = 222, R(2) = 0.114, P = 0.091) and 2008 (N = 222,!
  R(2) = 0.112, P = 0.096) (P<0.05) for the 222 journals. The relationship between self-citation rate and journal *impact factor* is discussed. Serials Review 2011; 37:171-173. (C) 2011 Elsevier Inc. All rights reserved.

Abstract:
Scientific journals must deal with the following questions concerning the predictive validity of editorial decisions. Is the best scientific work selected from submitted manuscripts? Does selection of the best manuscripts also mean selecting papers that after publication show top citation performance within their fields? Taking the journal Angewandte Chemie International Edition as an example, this study proposes a new methodology for investigating whether manuscripts that are most worthy of publication are in fact selected validly. First, the influence on citation of the accepted and rejected but then published elsewhere manuscripts was appraised on the basis of percentile impact classes scaled in a subfield of chemistry and, second, the association between the decisions on selection and the influence on citation of the manuscripts was determined by using a multilevel logistic regression for ordinal categories. This approach has many advantages over methodologies that were !
 used in previous research studies on the predictive validity of editorial selection decisions.
