Abstract:
Objective: To examine whether perceived information gain (IG) drives the publication of randomized trials in high-impact factor (IF) journals.
Study Design and Setting: We estimated IG as the Kullback-Leibler divergence, quantifying how much a new finding changes established knowledge. We used 67 meta-analyses (964 randomized trials) that include one or more trials from any of the three highest IF general medical journals (NEJM, JAMA, and Lancet). We calculated IG for the presence of a non-null effect (IG(1)) and IG for the effect size magnitude (IG(2)).
Results: Across meta-analyses, the summary correlation coefficient of IF was 0.23 (95% confidence interval [CI]: 0.14, 0.31) for IG(1) and 0.35 (95% CI: 0.25, 0.46) for IG(2). IF also correlated with the P-value of the results (r = 0.18), order of publication (r = -0.13), and number of events in the trial (r = 0.36). Multivariate regression including IG, order of publication, P-value, and the number of events showed that IG is an independent correlate of IF. IG(2) explained a substantially larger proportion of the variance in IF than IG(1).
Conclusion: Publication in journals with high IF is driven by how extensively the results of a study change prior perceptions of the evidence, independently of the statistical significance and size of the study. (c) 2012 Published by Elsevier Inc.

Abstract:
Introduction: Reporting of ethical committee (EC) approval and patient consent in publications involving human subjects may be lower than recommended. In this paper this ethical issue was analysed in the Portuguese Journal of Pulmonology and in the other two Portuguese medical journals with impact factor indexed in the ISI Web of Knowledge.
Methods: Reporting of EC approval and patient consent was searched in all publications involving human subjects published in the Acta Medica Portuguesa, Acta Reumatologica Portuguesa and Portuguese Journal of Pulmonology, from the 1st July 2010 until the 30th June 2011. The search also looked for the involvement of vulnerable and potentially identifiable subjects.
Results: Most of the analysed publications, which included a considerable proportion of vulnerable (23%) and of potentially identifiable case reports (14%), were case reports (49%). Overall EC approval ranged from 0% to 28%, in case reports and prospective studies, respectively, whereas overall patient consent ranged from 0% to 26%. There were not statistically significant differences in results among the selected journals.
Conclusions: Reporting of EC approval and patient consent in the three leading Portuguese medical journals has been lower than in their leading world counterparts. This should be taken into account and further audited in future, not only for the protection of the research subjects but also to maintain public trust in the process.

Abstract:
OBJECTIVE: To identify global research trends in neuroimaging diagnosis for cerebral infarction using a bibliometric analysis of the Web of Science.
DATA RETRIEVAL: We performed a bibliometric analysis of data retrieval for neuroimaging diagnosis for cerebral infarction containing the key words "CT, magnetic resonance imaging, MRI, transcranial Doppler, transvaginal color Doppler, digital subtraction angiography, and cerebral infarction" using the Web of Science.
SELECTION CRITERIA: Inclusion criteria were: (a) peer-reviewed articles on neuroimaging diagnosis for cerebral infarction which were published and indexed in the Web of Science; (b) original research articles and reviews; and (c) publication between 2004-2011. Exclusion criteria were: (a) articles that required manual searching or telephone access; and (b) corrected papers or book chapters.
MAIN OUTCOME MEASURES: (1) Annual publication output; (2) distribution according to country; (3) distribution according to institution; (4) top cited publications; (5) distribution according to journals; and (6) comparison of study results on neuroimaging diagnosis for cerebral infarction.
RESULTS: Imaging has become the predominant method used in diagnosing cerebral infarction. The most frequently used clinical imaging methods were digital subtraction angiography, CT, MRI, and transcranial color Doppler examination. Digital subtraction angiography is used as the gold standard. However, it is a costly and time-consuming invasive diagnosis that requires some radiation exposure, and is poorly accepted by patients. As such, it is mostly adopted in interventional therapy in the clinic. CT is now accepted as a rapid, simple, and reliable non-invasive method for use in diagnosis of cerebrovascular disease and preoperative appraisal. Ultrasonic Doppler can be used to reflect the hardness of the vascular wall and the nature of the plaque more clearly than CT and MRI.
CONCLUSION: At present, there is no unified standard of classification of cerebral infarction imaging. Detection of clinical super-acute cerebral infarction remains controversial due to its changes on imaging, lack of specificity, and its similarity to a space-occupying lesion. Neuroimaging diagnosis for cerebral infarction remains a highly active area of research and development.

Abstract:
A review of literature related to the existence of an invisible college community among coauthors of articles in top-rated social work journals indicated that an invisible college could promote quality scholarship but that coauthoring might be inadequately studied or valued in social work education. Social network analysis revealed a skeletal piece of the top-rated social work journal coauthor network, visualized it, documented its growth between the overlapping periods 2001-2005 and 2004-2008, and associated that growth with increasing citations of networked coauthors. Possible continued growth of the invisible college suggests the need to examine coauthoring, the means of evaluating coauthor contributions, and the content of social work scholarship.

Abstract:
Background: Citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. Journal Citation Reports (JCR) from Thomson Reuters provides annual report in the form of impact factor (IF) for each journal.
Objectives: We aimed to evaluate the citation parameters of Hepatitis Monthly by JCR in 2010 and compare them with GS and Sc.
Materials and Methods: All articles of Hepat Mon published in 2009 and 2008 which had been cited in 2010 in three databases including WoS, Sc and GS gathered in a spread-sheet. The IFs were manually calculated.
Results: Among the 104 total published articles the accuracy rates of GS and Sc in recording the total number of articles was 96% and 87.5%. There was a difference between IFs among the three databases (0.793 in ISI [Institute for Scientific Information], 0.945 in Sc and 0.85 GS). The missing rate of citations in ISI was 4% totally. Original articles were the main cited types, whereas, guidelines and clinical challenges were the least ones.
Conclusions: None of the three databases succeed to record all articles published in the journal. Despite high sensitivity of GS comparing to Sc, it cannot be a reliable source for indexing since GS has lack of screening in the data collection and low specificity. Using an average of three IFs is suggested to find the correct IF. Editors should be more aware on the role of original articles in increasing IF and the potential efficacy of review articles in long term impact factor. Published by Kowsar Corp, 2012. cc 3.0.

ABSTRACT: Using co-citation analysis, the present study attempts to
rationalize and organize the combined alliance and innovation literature
in order to determine its intellectual structure (i.e. its shared
attributes such as models, theories, methods, findings, and
implications), as well as to gain a deeper understanding of the most
important research trends. More specifically, our goals are: (1) to
delineate the intellectual structure of research on alliance and
innovation, as represented in the academic literature; (2) to determine
the subfields that constitute the intellectual structure and the
relationships, if any, between these subfields; (3) to identify
contributions that play a pivotal role in bridging two or more conceptual
domains of research; and finally, (4) to map the intellectual structure
in a two-dimensional space in order to visualize spatial distances
between intellectual themes. Implications for future studies are then
drawn.

ABSTRACT: Proposed by Hirsch as a quantitative measure of the total
output of a researcher, the h index does not work well in the field of
life sciences, where an author's position on a paper typically depends on
the author's contribution. We revise the h index by weighing first and
last authorship papers four times heavier than middle authorship papers.
The revised index (r) signifies a shift in how we evaluate the research
output in biology and medicine: it places more value on conducting and
directing original, independent investigations as compared with
contributing to projects conducted and directed by others.

ABSTRACT: The authors wished to evaluate whether their collection
housed the resources that their humanities faculty needed (and actually
used) for their research, with the hope of providing additional
illumination about general resource use by humanities scholars. This
study asks not whether anyone used what was already owned, but instead
whether the library owned what was needed. The answer to this question
might have implications for storage or weeding decisions, approval plans
for collections, and interlibrary loan. A citation analysis of 28
monographs published by their institution's humanities faculty between
2004 and 2009 was used to assess how many of their cited sources were
owned, how they were acquired (approval or firm order), their average
age, and interdisciplinary usage as evidenced by LC classification.
Subject areas assessed were History, Philosophy, Classics, and English.
Findings include that one quarter of sources cited were over 25 years
old, and that over the last fifteen years, the approval plan has provided
more than three quarters of the sources cited that were owned.

ABSTRACT: This paper reports the results of a citation analysis of
the scholarly literature of LGBT Studies. EBSCO's LGBT Life database was
used to gather a sample of 4,321 citations from core scholarly journals
in the field of LGBT Studies, covering the time period 1974 to 2010. The
analysis reveals that, although LGBT Studies as an area of scholarship
emerged from the gay rights activist movement of the 1960s and 1970s, the
field's literature appears to be firmly rooted in the mainstream academic
literature rather than in popular publications or community and activist
periodicals. However, the field has a very high rate of cross-
disciplinary citation and cites particularly heavily from medical
journals and books. In addition to illuminating the citation
characteristics of LGBT Studies, this paper presents lists of highly
cited books and journals that should prove useful for subject librarians
supporting LGBT Studies programs.
