Being the Ghost in the Machine: A Medical Ghostwriter's Personal View
Linda Logdberg, a medical ghostwriter for 11 years, provides a personal view of her former work and what she believes should be done about the problem of fraud in authorship
Bias in the journal impact factor
The ISI journal impact factor (JIF) is based on a sample that may represent
half the whole-of-life citations to some journals, but a small fraction (<10%)
of the citations accruing to other journals. This disproportionate sampling
means that the JIF provides a misleading indication of the true impact of
journals, biased in favour of journals that have a rapid rather than a
prolonged impact. Many journals exhibit a consistent pattern of citation
accrual from year to year, so it may be possible to adjust the JIF to provide a
more reliable indication of a journal's impact.Comment: 9 pages, 8 figures; one reference correcte
An examination of the reliability of prestigious scholarly journals: evidence and implications for decision-makers
In universities all over the world, hiring and promotion committees regularly hear the argument: âthis is important work because it is about to appear in prestigious journal Xâ. Moreover, those who allocate levels of research funding, such as in the multi-billion pound Research Assessment Exercise in UK universities, often come under pressure to assess research quality in a mechanical way by using journal prestige ratings. This paperâs results suggest that such tendencies are dangerous. It uses total citations over a quarter of a century as the criterion. The paper finds that it is far better to publish the best article in an issue of a medium-quality journal like the Oxford Bulletin of Economics and Statistics than to publish the worst article (or often the worst 4 articles) in an issue of a top journal like the American Economic Review. Implications are discussed
A system for success: BMC Systems Biology, a new open access journal
BMC Systems Biology is the first open access journal spanning the growing field of systems biology from molecules up to ecosystems. The journal has launched as more and more institutes are founded that are similarly dedicated to this new approach. BMC Systems Biology builds on the ongoing success of the BMC series, providing a venue for all sound research in the systems-level analysis of biology
Estimating geological CO2 storage security to deliver on climate mitigation
Carbon capture and storage (CCS) can help nations meet their Paris CO2 reduction commitments cost-effectively. However, lack of confidence in geologic CO2 storage security remains a barrier to CCS implementation. Here we present a numerical program that calculates CO2 storage security and leakage to the atmosphere over 10,000 years. This combines quantitative estimates of geological subsurface CO2 retention, and of surface CO2 leakage. We calculate that realistically well-regulated storage in regions with moderate well densities has a 50% probability that leakage remains below 0.0008% per year, with over 98% of the injected CO2 retained in the subsurface over 10,000 years. An unrealistic scenario, where CO2 storage is inadequately regulated, estimates that more than 78% will be retained over 10,000 years. Our modelling results suggest that geological storage of CO2 can be a secure climate change mitigation option, but we note that long-term behaviour of CO2 in the subsurface remains a key uncertainty

Constructing a Distant Future: Imaginaries in Geoengineering
We develop the concept of the distant future as a new way of seeing the future in collective efforts. While a near future is represented in practical terms and concerned with forming expectations and goals under conditions of uncertainty, a distant future is represented in stylized terms and concerned with imagining possibilities under conditions of ambiguity. Management research on future-oriented action has developed around problems of the near future. To explore distant futures, we analyze the case of geoengineering, a set of planetary-scale technologies that have been proposed as solutions to the threat of climate change. Geoengineering has increasingly been treated as if it were a reality, despite continued controversy and in the absence of any implementation. We find that societal-level imaginaries that were built on deeply-held moral bases and cosmologies underpinned the conception of geoengineering, and that a dialectic process of discursive attempts to reconcile oppositional imaginaries increased the concreteness and credibility of geoengineering so that it increasingly has been treated as an âas-ifâ reality. We suggest that distant futures orient collective efforts in distinctive ways, not as concrete guides for action but by expressing critiques and alternatives, that can become treated as âas-ifâ realities
Clues from joint inversion of tsunami and geodetic data of the 2011 Tohoku-oki earthquake
The 2011 Tohoku-oki (Mw 9.1) earthquake is so far the best-observed megathrust rupture, which allowed the collection of unprecedented offshore data. The joint inversion of tsunami waveforms (DART buoys, bottom pressure sensors, coastal wave gauges, and GPS-buoys) and static geodetic data (onshore GPS, seafloor displacements obtained by a GPS/acoustic combination technique), allows us to retrieve the slip distribution on a non-planar fault. We show that the inclusion of near-source data is necessary to image the details of slip pattern (maximum slip ~48â
m, up to ~35â
m close to the Japan trench), which generated the large and shallow seafloor coseismic deformations and the devastating inundation of the Japanese coast. We investigate the relation between the spatial distribution of previously inferred interseismic coupling and coseismic slip and we highlight the importance of seafloor geodetic measurements to constrain the interseismic coupling, which is one of the key-elements for long-term earthquake and tsunami hazard assessment
