TITLE: SCALE-FREE NETWORKS CAN BE LINEAR-WORLD (Article, English)

ABSTRACT: It was generally believed that scale-free networks would
be small-world. In this paper, two models, named Model A and Model B, are proposed to show that certain scale-free networks can be linear-world instead of small-world. By linear-world, it means that the average path length L of the network grows linearly with the total number of nodes N, i.e., L similar to N. Model A generates a deterministic scale-free network with high assortativity and numerical simulations demonstrate that the network is linear-world when it satisfies degree exponent lambda
> 1. Model B constructs a partially deterministic scale-free network,
which is connected by identical small scale-free networks following certain rules. Analytical arguments and numerical simulations both yield L similar to N which suggests that it is also linear-world. It is further discussed in this paper that the network generated by Model B could be either correlated or uncorrelated. This suggests that, inconsistent with the results in related works, uncorrelated scale-free networks can also be linear-world.

KEYWORDS+: ECONOMICS DEPARTMENTS; EUROPEAN ECONOMICS; QUALITY;
AMERICAN; RANKINGS; TRENDS; OUTPUT; US
ABSTRACT: The scientific community is just that a community and the
success/influence of any one individual likely reflects, at least in certain measure, the contributions made previously by others. This suggests that rather than merely ranking economists on the basis of raw citation counts, one might gain real insights about the giants laboring in relative obscurity by identifying who the authors of exceptionally influential papers drew their inspiration from. We identify the most- highly-cited (409) papers published in economics from 20012005, then examine who the authors of these high-impact papers drew from in terms of developing the ideas/arguments/applications presented in these papers. We find that a very small group of individuals had a comparatively large impact on the economics profession, in terms of influencing the subsequent work of authors of extraordinarily highly-cited papers.
Further, there is relatively little consistency between our list of giants and Nobel Prize winners in Economics.

ABSTRACT: Scholars widely acknowledge that university research is
critical to innovation and entrepreneurship. Much of the literature on university research, however, evokes a linear model from "science to products" and focuses, therefore, upon a limited set of indicators such as patents and licenses. Such a perspective runs the danger of missing the myriad ways in which science and commerce are intertwined and the myriad ways in which these activities might be assessed. In this paper, I address the question of how different measures reflect different perspectives and biases by investigating the production and diffusion of research associated with one of Stanford University's most prolific interdisciplinary centers, the Center for Computer Research in Music and Acoustics (CCRMA). I draw upon a unique data set that captures activities and engagement surrounding CCRMA for its 30-year history through a wide variety of measures, ranging from publication citations to industrial affiliates to personnel mobility. Employing the analytic categories of "description" and "enactment," and distinguishing between "indicators"
and "pathways," I show how different measures reflect different activities and learning processes, and how they dramatically alter perceptions of active individuals, organizational reach, and timing and sequencing of activities. Building on these findings, I present a more complete model of university research production and diffusion, I discuss how alternative measures challenge certain assumptions in the literature, and I suggest concrete policy initiatives to improve our measurement and assessment of university research.

ABSTRACT: We analyze the role of social capital in academic
careers. We distinguish between ties with reputed scientists and laboratories (scientific and technical human capital) and ties with influential actors with respect to recruitment/promotion decisions (political capital). We use institution-wise bibliometric indicators to measure separately the two types of capital for a large sample of French and Italian academic physicists between 2000 and 2003/2005. Controlling for scientific productivity, seniority and gender issues, career progress is explained by: the scientist's affiliation to important public research organizations (scientific and technical human capital - France); his/her social ties with senior members of the discipline, who exercise control over careers (political capital - Italy), and the commitment to work with senior colleagues in his/her own university (political capital - Italy).
Significant differences exist between the two countries also with respect to the importance of productivity, seniority, and gender. (C) 2011 Elsevier B.V. All rights reserved.

ABSTRACT: This study gives an overview of the process of clustering
scientific disciplines using hybrid methods, detecting and labelling emerging topics and analysing the results using bibliometrics methods.
The hybrid clustering techniques are based on biblographic coupling and text-mining and 'core documents', and cross-citation links are used to identify emerging fields. The collaboration network of those countries that proved to be most active in the underlying disciplines, in combination with a set of standard indicators, form the groundwork for the bibliometric analysis of the detected emerging research topics.

TITLE: Endorsement of the CONSORT Statement by High-Impact
Medical Journals in China: A Survey of Instructions for Authors and
Published Papers (Article, English)

KEYWORDS+: RANDOMIZED CONTROLLED-TRIALS; QUALITY; EDITORS
ABSTRACT: Background: The CONSORT Statement is a reporting
guideline for authors when reporting randomized controlled trials (RCTs).
It offers a standard way for authors to prepare RCT reports. It has been endorsed by many high-impact medical journals and by international editorial groups. This study was conducted to assess the endorsement of the CONSORT Statement by high-impact medical journals in China by reviewing their instructions for authors.
Methodology/Principal Findings: A total of 200 medical journals were selected according to the Chinese Science and Technology Journal Citation Reports, 195 of which publish clinical research papers. Their instructions for authors were reviewed and all texts mentioning the CONSORT Statement or CONSORT extension papers were extracted. Any mention of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (URM) developed by the International Committee of Medical Journal Editors (ICMJE) or 'clinical trial registration' was also extracted. For journals endorsing the CONSORT Statement, their most recently published RCT reports were retrieved and evaluated to assess whether the journals have followed what the CONSORT Statement required.
Out of the 195 medical journals publishing clinical research papers, only six (6/195, 3.08%) mentioned 'CONSORT' in their instructions for authors; out of the 200 medical journals surveyed, only 14 (14/200, 7.00%) mentioned 'ICMJE' or 'URM' in their instructions for authors, and another five journals stated in their instructions for authors that clinical trials should have trial registration numbers and that priority would be given to clinical trials which had been registered. Among the 62 RCT reports published in the six journals endorsing the CONSORT Statement, 20 (20/62, 32.26%) contained flow diagrams and only three (3/62, 4.84%) provided trial registration information.
Conclusions/Significance: Medical journals in China endorsing either the CONSORT Statement or the ICMJE's URM constituted a small percentage of the total; all of these journals used ambiguous language regarding what was expected of authors.
